INTRODUCTION: To verify the value of the pathological criteria for additional treatment in locally resected pT1 colorectal carcinoma (CRC) which have been used in the Japanese Society for Cancer of the Colon and Rectum (JSCCR) guidelines since 2009. METHODS: We enrolled 4,667 patients with pT1 CRC treated at 27 institutions between July 2009 and December 2016 (1,257 patients with local resection alone [group A], 1,512 patients with additional surgery after local resection [group B], and 1,898 patients with surgery alone [group C]). All 5 factors of the JSCCR guidelines (submucosal resection margin, tumor histologic grade, submucosal invasion depth, lymphovascular invasion, and tumor budding) for lymph node metastasis (LNM) had been diagnosed prospectively. RESULTS: Any of the risk factors were present in 3,751 patients. The LNM incidence was 10.4% (95% confidence interval 9.4-11.5) in group B/C patients with risk factors, whereas it was 1.8% (95% confidence interval 0.4-5.3) in those without risk factors (P < 0.01). In group A, the incidence of recurrence was 3.6% in patients with risk factors, but it was only 0.4% in patients without risk factors (P < 0.01). The disease-free survival rate of group A patients classified as risk positive was significantly worse than those of groups B and C patients. However, the 5-year disease-free survival rate in group A patients with no risk was 99.6%. DISCUSSION: Our large-scale real-world multicenter study demonstrated the validity of the JSCCR criteria for pT1CRC after local resection, especially regarding favorable outcomes in patients with low risk of LNM.

IMPACT: This article will be of value to the digital governance policy-makers and particularly to those suffering from digital red tape across the public sector. It identifies Covid 19 digital pandemic prevention regulations as a counter-example, demonstrating the existence of digital red tape and revealing its impact on non-compliance. The more citizens viewed the regulations as digital red tape, the more dissatisfied they felt and the more they violated the regulations. The authors advise policy-makers to simplify burdensome, ineffective and non-necessary procedures when designing digital regulations to avoid citizen dissatisfaction. When perceived infection risk was high, dissatisfied citizens tended to comply with digital regulations. Conversely, non-compliance due to dissatisfaction with digital regulations increased significantly when citizens perceived the infection risk as low. To ensure compliance, eliminating dysfunctional rules and regulations was particularly important when the infection risk declined. Prior studies have viewed digital governance as a powerful tool for eliminating red tape. However, based on a survey of 1,080 participants, digital pandemic prevention regulations were found to be perceived as burdensome, ineffective and unnecessary. Citizen dissatisfaction with digital red tape led to non-compliant behaviours. The perception of a low infection risk was an important moderating factor exacerbating non-compliant behaviours. This study contributes to the assessment of the negative impacts of digital red tape on citizens, providing insights for studying the dark side of digital governance. [ABSTRACT FROM AUTHOR]

Background/objectiveGuidelines recommend less intensive glycemic treatment and less frequent glucose monitoring for nursing home (NH) residents. However, little is known about the frequency of fingerstick (FS) glucose monitoring in this population. Our objective was to examine the frequency of FS glucose monitoring in Veterans Affairs (VA) NH residents with diabetes mellitus, type II (T2DM).Design and settingNational retrospective cohort study in 140 VA NHs.ParticipantsNH residents with T2DM and older than 65 years admitted to VA NHs between 2013 and 2015 following discharge from a VA hospital.MeasurementsNH residents were classified into five groups based on their highest hypoglycemia risk glucose-lowering medication (GLM) each day: no GLMs; metformin only; sulfonylureas; long-acting insulin; and any short-acting insulin. Our outcome was a daily count of FS measurements.ResultsAmong 17,474 VA NH residents, mean age was 76 (standard deviation (SD) = 8) years and mean hemoglobin A1c was 7.6% (SD = 1.5%). On day 1 after NH admission, 49% of NH residents were on short-acting insulin, decreasing slightly to 43% at day 90. Overall, NH residents had an average of 1.9 (95% confidence interval (CI) = 1.8-1.9) FS measurements on NH day 1, decreasing to 1.4 (95% CI = 1.3-1.4) by day 90. NH residents on short-acting insulin had the most frequent FS measurements, with 3.0 measurements (95% CI = 2.9-3.0) on day 1, decreasing to 2.6 measurements (95% CI = 2.5-2.7) by day 90. Less frequent FS measurements were seen for NH residents receiving long-acting insulin (2.1 (95% CI = 2.0-2.2) on day 1) and sulfonylureas (1.7 (95% CI = 1.5-1.8) on day 1). Even NH residents on metformin monotherapy had 1.1 (95% CI = 1.1-1.2) measurements on day 1, decreasing to 0.5 (95% CI = 0.4-0.6) measurements on day 90.ConclusionAlthough guidelines recommend less frequent glucose monitoring for NH residents, we found that many VA NH residents receive frequent FS monitoring. Given the uncertain benefits and potential for substantial patient burdens and harms, our results suggest decreasing FS monitoring may be warranted for many low hypoglycemia risk NH residents.

OBJECTIVE: Patients who have undergone breast-conserving surgery may experience fear of recurrence. Post-operative granulation tissue and fat necrosis are common issues for these patients. As a result, additional examinations may increase, which can entail increased costs and stress for patients. In this study, if oncoplastic breast-conserving surgery causes additional imaging and unnecessary additional evaluations. PATIENTS AND METHODS: We retrospectively analyzed data from 432 patients who had undergone breast-conserving surgery in the same surgical unit between 2013 and 2017. We separated the patients into two main groups: Group 1 were those operated with conservative breast-conserving surgery, while Group 2 had operations using oncoplastic breast-conserving surgery techniques. The two groups were compared in terms of post-operative radiological examinations, suspected radiological findings, and biopsy needs. RESULTS: There were 203 patients in Group 1 and 229 in Group 2. The median follow-up time was 66 months (range 12-109). Additional mammography use was higher in the second group (p=0.003). However, the two groups had no statistical differences for additional imaging and biopsy needs in general (p=0.138). Sixty-two patients (14.3%) had biopsies with suspicious radiological findings (15.8% vs. 13.1%). Eight (12.8%) of these patients had malignant results. There were local recurrences in six patients, one in the first group and five in the second group (p=0.084). CONCLUSIONS: Oncoplastic breast-conserving surgery may increase post-operative mammography use. However, there is no statistical difference between the two groups for either additional imaging in total or in biopsy needs. [ABSTRACT FROM AUTHOR]

BackgroundDetection of cystic lesions of the pancreas has outpaced our ability to stratify low-grade cystic lesions from those at greater risk for pancreatic cancer, raising a concern for overtreatment.MethodsWe developed a Markov decision model to determine the cost-effectiveness of guideline-based management for asymptomatic pancreatic cysts. Incremental costs per quality-adjusted life year gained and survival were calculated for current management guidelines. A sensitivity analysis estimated the effect on cost-effectiveness and mortality if overtreatment of low-grade cysts is avoided, and the sensitivity and specificity thresholds required of methods of cyst stratification to improve costs expended.Results"Surveillance" using current management guidelines had an incremental cost-effectiveness ratio of $171,143/quality adjusted life year compared with no surveillance or operative treatment ("do nothing"). An incremental cost-effectiveness ratio for surveillance decreases to $80,707/quality adjusted life year if the operative overtreatment of low-grade cysts was avoided. Assuming a societal willingness-to-pay of $100,000/quality adjusted life year, the diagnostic specificity for high-risk cysts must be >67% for surveillance to be preferred over surgery and "do nothing." Changes in sensitivity alone cannot make surveillance cost-effective. Most importantly, survival in surveillance is worse than "do nothing" for 3 years after cyst diagnosis, although long-term survival is improved. The disadvantage is eliminated when overtreatment of low-grade cysts is avoided.ConclusionCurrent management of pancreatic cystic lesions is not cost-effective and may increase mortality owing to overtreatment of low-grade cysts. The specificity for risk stratification for high-risk cysts must be greater than 67% to make surveillance cost-effective.

BackgroundThe number of trauma patients on prehospital novel oral anticoagulants (NOACs) is increasing. After an initial negative computed tomography of the head (CTH), practice patterns are variable for obtaining repeat CTH to evaluate for delayed intracranial hemorrhage (ICH-d). However, the risks and outcomes of ICH-d for patients on NOACs are unclear. We hypothesized that, for these patients, the incidence of ICH-d is low, similar to that of warfarin, and when it occurs, it does not result in clinically significant worse outcomes.MethodsFive level 1 trauma centers in Northern California participated in a retrospective review of anticoagulated trauma patients. Patients were included if their initial CTH was negative. Primary outcomes were incidence of ICH-d, neurosurgical intervention, and death. Patient factors associated with the outcome of ICH-d were determined by multivariable regression.ResultsFrom 2016 to 2018, 777 patients met the inclusion criteria (NOAC, n = 346; warfarin, n = 431), 54% of whom received a repeat CTH. Delayed intracranial hemorrhage incidence was 2.3% in the NOAC group and 4% in the warfarin group (p = 0.31). No NOAC patient with ICH-d required neurosurgical intervention or died because of their head injury. Two warfarin patients received neurosurgical intervention, and three died from their head injury. Head Abbreviated Injury Scale ≥3 was associated with increased odds of developing ICH-d (adjusted odds ratio, 32.70; p < 0.01).ConclusionThe incidence of ICH-d in patients taking NOAC is low. In this study, patients on NOACs who developed ICH-d after an initial negative CTH did not need neurosurgical intervention or die from their head injury. Repeat CTH in this patient population does not appear necessary.Level of evidencePrognostic/epidemiologic study, level III.Therapeutic, level IV.

Rationale: Medical interventions that prolong life without achieving an effect that the patient can appreciate as a benefit are often considered futile or inappropriate by healthcare providers. In recent years, a multicenter guideline has been released with recommendations on how to resolve conflicts between families and clinicians in these situations and to increase public engagement. Although laypeople are acknowledged as important stakeholders, their perceptions and understanding of the terms "potentially inappropriate" or "futile" treatment have received little formal evaluation.Objectives: To evaluate the community perspective about the meaning of futile treatment.Methods: Six focus groups (two groups each of ages 75 yr) were convened to explore what constitutes futile treatment and who should decide in situations of conflict between doctors and families. Focus group discussions were analyzed using grounded theory.Results: There were 39 participants aged 18 or older with at least one previous hospitalization (personal or by immediate relative). When asked to describe futile or inappropriate treatment, community members found the concept difficult to understand and the terminology inadequate, though when presented with a case describing inappropriate treatment, most participants recognized it as the provision of inappropriate treatment. Several themes emerged regarding participant difficulty with the concept, including inadequate physician-patient communication, lack of public emphasis on end-of-life issues, skepticism that medical treatment can be completely inappropriate, and doubts and fears that medical futility could undermine patient and/or family autonomy. Participants also firmly believed that in situations of conflict families should be the ultimate decision-makers.Conclusions: Public engagement in policy development and discourse around medical futility will first require intense education to familiarize the lay public about use of inappropriate treatment at the end of life.

Osteoporosis is a chronic condition that reflects reduced bone strength and an associated increased risk for fracture. As a chronic condition, osteoporosis generally requires sustained medical intervention(s) to limit the risks for additional bone loss, compromise of skeletal integrity, and fracture occurrence. Further complicating this issue is the fact that the abrupt cessation of some therapies can be associated with an increased risk for harm. It is in this context that the COVID-19 pandemic has brought unprecedented disruption to the provision of health care globally, including near universal requirements for social distancing. In this Perspective, we provide evidence, where available, regarding the general care of patients with osteoporosis in the COVID-19 era and provide clinical recommendations based primarily on expert opinion when data are absent. Particular emphasis is placed on the transition from parenteral osteoporosis therapies. It is hoped that these recommendations can be used to safely guide care for patients with osteoporosis until a return to routine clinical care standards is available. © 2020 American Society for Bone and Mineral Research.

INTRODUCTION: Medical pluralism, or concurrent utilisation of multiple therapeutic modalities, is common in various international contexts, and has been characterised as a factor contributing to poor health outcomes in low-resource settings. Traditional healers are ubiquitous providers in most regions, including the study site of southwestern Uganda. Where both informal and formal healthcare services are both available, patients do not engage with both options equally. It is not well understood why patients choose to engage with one healthcare modality over the other. The goal of this study was to explain therapeutic itineraries and create a conceptual framework of pluralistic health behaviour. METHODS: In-depth interviews were conducted from September 2017 to February 2018 with patients seeking care at traditional healers (n=30) and at an outpatient medicine clinic (n=30) in Mbarara, Uganda; the study is nested within a longitudinal project examining HIV testing engagement among traditional healer-using communities. Inclusion criteria included age ≥18 years, and ability to provide informed consent. Participants were recruited from practices representing the range of healer specialties. Following an inductive approach, interview transcripts were reviewed and coded to identify conceptual categories explaining healthcare utilisation. RESULTS: We identified three broad categories relevant to healthcare utilisation: (1) traditional healers treat patients with care; (2) biomedicine uses modern technologies and (3) peer testimony influences healthcare engagement. These categories describe variables at the healthcare provider, healthcare system and peer levels that interrelate to motivate individual engagement in pluralistic health resources. CONCLUSIONS: Patients perceive clear advantages and disadvantages to biomedical and traditional care in medically pluralistic settings. We identified factors at the healthcare provider, healthcare system and peer levels which influence patients therapeutic itineraries. Our findings provide a basis to improve health outcomes in medically pluralistic settings, and underscore the importance of recognising traditional healers as important stakeholders in community health.

BackgroundCoronary artery calcification is a marker of underlying atherosclerotic vascular disease. The absence of coronary artery calcification is associated with a low prevalence of obstructive coronary artery disease (CAD), but it cannot be ruled out completely. We sought to develop a clinical tool that can be added to Agatston score of zero to rule out obstructive CAD with high accuracy.MethodsWe developed a clinical score retrospectively from a cohort of 4903 consecutive patients with an Agatston score of zero. Patients with prior diagnosis of CAD, coronary percutaneous coronary intervention, or surgical revascularization were excluded. Obstructive CAD was defined as any epicardial vessel diameter narrowing of ≥50%. The score was validated using an external cohort of 4290 patients with an Agatston score of zero from a multinational registry.ResultsThe score consisted of 7 variables: age, sex, typical chest pain, dyslipidemia, hypertension, family history, and diabetes mellitus. The model was robust with an area under the curve of 0.70 (95% CI, 0.65-0.76) in the derivation cohort and 0.69 (95% CI, 0.65-0.72) in the validation cohort. Patients were divided into 3 risk groups based on the score: low (≤6), intermediate (7-13), and high (≥14). Patients who score ≤6 have a negative likelihood ratio of 0.42 for obstructive CAD, whereas those who score ≥14 have a positive likelihood ratio of >5.5 for obstructive CAD. The outcome was ruled out in >98% of patients with a score ≤6 in the validation cohort.ConclusionsWe developed a score that may be used to identify the likelihood of obstructive CAD in patients with an Agatston score of zero, which may be used to direct the need for additional testing. However, the results of this retrospective analysis are hypothesis generating and before clinical implementation should be validated in a trial with a prospectively collected data.

ObjectiveIn preparation for a multisite antibiotic stewardship intervention, we assessed knowledge and attitudes toward management of asymptomatic bacteriuria (ASB) plus teamwork and safety climate among providers, nurses, and clinical nurse assistants (CNAs).DesignProspective surveys during January-June 2018.SettingAll acute and long-term care units of 4 Veterans' Affairs facilities.MethodsThe survey instrument included 2 previously tested subcomponents: the Kicking CAUTI survey (ASB knowledge and attitudes) and the Safety Attitudes Questionnaire (SAQ).ResultsA total of 534 surveys were completed, with an overall response rate of 65%. Cognitive biases impacting management of ASB were identified. For example, providers presented with a case scenario of an asymptomatic patient with a positive urine culture were more likely to give antibiotics if the organism was resistant to antibiotics. Additionally, more than 80% of both nurses and CNAs indicated that foul smell is an appropriate indication for a urine culture. We found significant interprofessional differences in teamwork and safety climate (defined as attitudes about issues relevant to patient safety), with CNAs having highest scores and resident physicians having the lowest scores on self-reported perceptions of teamwork and safety climates (P < .001). Among providers, higher safety-climate scores were significantly associated with appropriate risk perceptions related to ASB, whereas social norms concerning ASB management were correlated with higher teamwork climate ratings.ConclusionsOur survey revealed substantial misunderstanding regarding management of ASB among providers, nurses, and CNAs. Educating and empowering these professionals to discourage unnecessary urine culturing and inappropriate antibiotic use will be key components of antibiotic stewardship efforts.

BackgroundThe necessity for rapid evaluation and treatment of acute ischemic stroke with intravenous tPA (tissue-type plasminogen activator) may increase the risk of administrating tPA to patients presenting with noncerebrovascular conditions that closely resemble stroke (stroke mimics). However, there are limited data on thrombolysis safety in stroke mimics.Methods and resultsUsing data from the Get With The Guidelines-Stroke Registry, we identified 72 582 patients with suspected ischemic stroke treated with tPA from 485 US hospitals between January 2010 and December 2017. We documented the use of tPA in stroke mimics, defined as patients who present with stroke-like symptoms, but after workup are determined not to have suffered from a stroke or transient ischemic attack, and compared characteristics and outcomes in stroke mimics versus those with ischemic stroke. Overall, 3.5% of tPA treatments were given to stroke mimics. Among them, 38.2% had a final nonstroke diagnoses of migraine, functional disorder, seizure, and electrolyte or metabolic imbalance. Compared with tPA-treated true ischemic strokes, tPA-treated mimics were younger (median 54 versus 71 years), had a less severe National Institute of Health Stroke Scale (median 6 versus 8), and a lower prevalence of cardiovascular risk factors, except for a higher prevalence of prior stroke/transient ischemic attack (31.3% versus 26.1%, all P

Background Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that affects the upper and lower motor neurons. The correct diagnosis at the onset of the disease is sometimes very difficult, due to the symptoms being very similar to those of other neurological syndromes. Objective This study aimed to analyze the initial manifestations, the specialty of the first physician visited due the initial complaint, the misdiagnoses, as well as the unnecessary surgical interventions in a new ALS Brazilian population. Methods The medical records of 173 patients with typical ALS were reviewed. Results The present study demonstrated that other symptoms, besides weakness, were very frequent as initial presentation of ALS, and orthopedics was the medical specialty most sought by patients at the onset of symptoms. Our frequency of misdiagnoses was 69.7%, and in 7.1% of them, an unnecessary surgical intervention was performed. Conclusions Amyotrophic lateral sclerosis presents a very large pool of signs and symptoms; therefore, there is an urgent need of increasing the disease awareness to other specialties due to the high frequency of misdiagnoses observed in clinical practice.

ObjectiveTo evaluate whether conducting a bimanual examination prior to medication abortion (MAB) provision results in meaningful changes in gestational age (GA) assessment after patient-reported last menstrual period (LMP) in Nepal.Study designWomen ages 16-45 (n=660) seeking MAB at twelve participating pharmacies and government health facilities, between October 2014 and September 2015, self-reported LMP. Trained auxiliary nurse midwives assessed GA using a bimanual exam after recording LMP. We compared GA assessments as measured via patient-reported LMP alone versus via LMP plus bimanual exam.ResultsOverall, 660 women (326 at pharmacies, 334 at health facilities) presented for MAB, and 95% were able to provide an LMP. Overall agreement between LMP alone and LMP with bimanual exam was 99.3%. If LMP alone had been used without bimanual exam, fewer than one in 200 women would have been given MAB beyond the legal gestational limit. Among the three women who were ≤63 days by LMP but >63 days by bimanual exam, only one would have received MAB beyond 70 days gestation. Fewer than one in 600 women would not have received MAB care when eligible by adding a bimanual exam.ConclusionThere was high agreement between LMP alone and LMP plus bimanual exam. Routine bimanual exam may not be essential for safe and effective MAB care for women who are able to report an LMP. Removing the bimanual exam requirement could decrease barriers to provision outside of currently approved clinical settings and allow for expanded abortion access through provision by providers without bimanual exam training or facilities.ImplicationsRoutine bimanual exams may not be essential for safe medication abortion provision by trained clinicians in pharmacies and health facilities in low resource settings like Nepal.

Introduction: The diagnostic evaluation of men with suspected prostate cancer (PCa) yet inconclusive MRI (PI-RADS ≤ 3) presents a common clinical challenge. [ 68 Ga]Ga-labelled prostate-specific membrane antigen ([ 68 Ga]Ga-PSMA) positron emission tomography/computed tomography (PET/CT) has shown promise in identifying clinically significant PCa (csPCa). We aim to establish a diagnostic model incorporating PSMA-PET to enhance the diagnostic process of csPCa in PI-RADS ≤ 3 men., Materials and Methods: This study retrospective included 151 men with clinical suspicion of PCa and PI-RADS ≤ 3 MRI. All men underwent [ 68 Ga]Ga-PSMA PET/CT scans and ultrasound/MRI/PET fusion-guided biopsies. csPCa was defined as Grade Group ≥ 2. PRIMARY-scores from PSMA-PET scans were evaluated. A diagnostic model incorporating PSMA-PET and prostate-specific antigen (PSA)-derived parameters was developed. The discriminative performance and clinical utility were compared with conventional methods. Internal validation was conducted using a fivefold cross-validation with 1000 iterations., Results: In this PI-RADS ≤ 3 cohort, areas-under-the-curve (AUCs) for detecting csPCa were 0.796 (95%CI, 0.738-0.853), 0.851 (95%CI, 0.783-0.918) and 0.806 (95%CI, 0.742-0.870) for PRIMARY-score, SUVmax and routine clinical PSMA-PET assessment, respectively. The diagnostic model comprising PRIMARY-score, SUVmax and serum free PSA/total PSA (fPSA/tPSA) achieved a significantly higher AUC of 0.906 (95%CI, 0.851-0.961) compared to strategies based on PRIMARY-score or SUVmax (P < 0.05) and markedly superior to conventional strategies typically based on PSA density (P < 0.001). The average fivefold cross-validated AUC with 1000 iterations was 0.878 (95%CI, 0.820-0.954). Theoretically, using a threshold of 21.6%, the model could have prevented 78% of unnecessary biopsies while missing only 7.8% of csPCa cases in this cohort., Conclusions: A novel diagnostic model incorporating PSMA-PET derived metrics-PRIMARY-score and SUVmax-along with serum fPSA/tPSA, has been developed and validated. The integrated model may assist clinical decision-making with enhanced diagnostic accuracy over the individual conventional metrics. It has great potential to reduce unnecessary biopsies for men with PI-RADS ≤ 3 MRI results and warrants further prospective and external evaluations., Competing Interests: Declarations.

Background: Endoscopic retrograde cholangiopancreatography (ERCP) is the first-line procedure for choledocholithiasis treatment. However, it is associated with a 10 % rate of adverse events. Spontaneous migration of common bile duct (CBD) stones occurs in 6-33 % of choledocholithiasis cases, making ERCP avoidable. This study aimed to identify predictors of spontaneous CBD stones' migration., Methods: Retrospective study including patients diagnosed with choledocholithiasis and submitted to ERCP. Patients were divided into 2 groups considering spontaneous stone migration (i.e.: the absence of CBD stones on ERCP). Data on patients' characteristics, imaging findings, biochemical analysis, and ERCP procedure were analyzed to identify predictors of spontaneous migration of CBD stones., Results: 334 patients with a mean age of 71.7 years were included in the study: 76.6 % without and 23.4 % with spontaneous migration of CBD stones. Although some patients' features (gender and clinical presentation), imaging findings (diameters of the largest stone and CBD), biochemical analysis (bilirubin levels at diagnosis and pre-ERCP), and ERCP procedure characteristics (time from diagnosis to ERCP) were different between groups, only three variables were defined as predictors: the absence of acute cholangitis, the largest stone diameter ≤5 mm, and the bilirubin levels pre-ERCP ≤ 2mg/dL. When using those variables together there was a chance of 81-86 % to correctly distinguishing patients with and without spontaneous CBD stone migration., Conclusion: The size of the largest stone at diagnosis was validated as a predictor of CBD stones' spontaneous migration. Furthermore, two new predictors were identified: bilirubin levels pre-ERCP ≤ 2 mg/dL, and no acute cholangitis at the clinical presentation of choledocholithiasis. EUS and ERCP in the same session should be considered in patients with factors predictive of stone migration, especially when combined, to minimize unnecessary ERCP and possible complications., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Jorge Canena reports a relationship with Boston Scientific Corporation that includes: consulting or advisory.

Background: We hypothesised that the implementation of an electronic medical record (EMR) embedded perioperative clinical decision support (CDS) application, Anesthesia Testing Guidelines (ATG), would result in at least a 10% reduction of unnecessary perioperative testing in patients undergoing elective surgeries., Methods: The development and implementation of ATG occurred in several phases: 1) team development, 2) development of an embedded EMR application, 3) creation of ATG training and education toolkit, and 4) implementation involving promoting ATG through training and education, addressing challenges, and monitoring compliance. The proportions of patients with any overutilisation across 19 perioperative tests were compared between the baseline cohort and the ATG implementation cohort., Findings: The overutilisation of perioperative tests was observed in 77.6% of the baseline cohort (n = 59,799) and 68.1% in the ATG cohort (n = 132,131), with a significant 12.2% reduction over two years of implementation (p < 0.0001). The two tests with the greatest amount of associated cost were reduced by 46% for chest X-rays and 39% for complete metabolic panels. The health system was able to reduce overall costs by 22% from baseline. Interrupted time series analysis estimated an immediate 7.5% decrease in monthly overutilisation when ATG initially launched, and it continued to decrease by 0.24% per month., Interpretation: Our findings suggest CDS ATG is a successful tactic to reduce unnecessary preoperative testing while maintaining quality of care and improving cost avoidance. This type of CDS implementation approach transforms organisational behaviour and medical practices to follow defined guidelines, thereby improving the value of care., Funding: CDS ATG was supported by UPMC Department of Anesthesiology and Perioperative Medicine and UPMC Department of Finance., Competing Interests: Declaration of interests The authors declare no relevant conflicts of interests for this manuscript at any time in the present or in the past 36 months, nor do the authors have any relavant competing interests, including support, grants or contracts from entities, consulting fees, royalties or licenses, payment or honoraria for lectures, presentations, speakers bureaus, manuscript writing, or educational events, payment for expert testimony, support for attending meetings and/or travel, patents planned, issued or pending, participation on data safety monitoring board or advisory boards, leadership or fiduciary role in other board, society, committee, or advocacy group, paid or unpaid, stock or stock options, receipt of equipment, materials, drugs, medical writing, gifts, or other services, or other financial or non-financial interests., (Copyright © 2024 The Authors.

Context: Reducing unnecessary imaging in emergency departments (EDs) for children with minor traumatic brain injuries (mTBIs) has been encouraged., Objective: Our objective was to systematically review the effectiveness of interventions to decrease imaging in this population., Data Sources: Eight electronic databases and the gray literature were searched., Study Selection: Comparative studies assessing ED interventions to reduce imaging in children with mTBIs were eligible., Data Extraction: Two independent reviewers screened studies, completed a quality assessment, and extracted data. The median of relative risks with interquartile range (IQR) are reported. A multivariable metaregression identified predictors of relative change in imaging., Results: Twenty-eight studies were included, and most (79%) used before-after designs. The Pediatric Emergency Care Applied Research Network (PECARN) rule was the most common intervention (71%); most studies (75%) used multifaceted interventions (median components: 3; IQR: 1.75 to 4). Before-after studies assessing multi-faceted PECARN interventions reported decreased computed tomography (CT) head imaging (relative risk = 0.73; IQR: 0.60 to 0.89). Higher baseline imagine (P < .001) and additional intervention components (P = .008) were associated with larger imaging decreases., Limitations: The limitations of this study include the inconsistent reporting of important outcomes and that the results are based on non-randomized studies., Conclusions: Implementing interventions in EDs with high baseline CT ordering using complex interventions was more likely to reduce head imaging in children with mTBIs. Including the PECARN decision rule in the intervention strategy decreased orders by a median of 27%. Further research could provide insight into which specific factors influence successful implementation and sustained effects., (Copyright © 2024 by the American Academy of Pediatrics.)

Background We aim to validate the diagnostic performance of thyroid core needle biopsy (CNB) for diagnosing malignancy in clinical settings to align with the changes made in recently updated thyroid CNB guidelines. Methods We retrospectively analyzed 1,381 thyroid CNB and 2,223 fine needle aspiration (FNA) samples. The FNA and CNB slides were interpreted according to the Bethesda System for Reporting Thyroid Cytopathology and updated practice guidelines for thyroid CNB, respectively. Results Compared to FNA, CNB showed lower rates of inconclusive results: categories I (2.8% vs. 11.2%) and III (1.2% vs. 6.2%), and higher rates of categories II (60.9% vs. 50.4%) and IV (17.5% vs. 2.0%). The upper and lower bounds of the risk of malignancy (ROM) for category IV of CNB were 43.2% and 26.6%, respectively. The CNB subcategory IVb with nuclear atypia had a higher ROM than the subcategory without nuclear atypia (40%–62% vs. 23%–36%). In histologically confirmed cases, there was no significant difference in the diagnostic performance between CNB and FNA for malignancy. However, neoplastic diseases were more frequently detected by CNB than by FNA (88.8% vs. 77.6%, P=0.046). In category IV, there was no difference in unnecessary surgery rate between CNB and FNA (4.7% vs. 6.9%, P=0.6361). Conclusion Thyroid CNB decreased the rate of inconclusive results and showed a higher category IV diagnostic rate than FNA. The revised guidelines for thyroid CNB proved to be an excellent reporting system for assessing thyroid nodules.

BackgroundFactors leading to inappropriate critical care, that is treatment that should not be provided because it does not offer the patient meaningful benefit, have not been rigorously characterized.ObjectiveWe explored medical record documentation about patients who received inappropriate critical care and those who received appropriate critical care to examine factors associated with the provision of inappropriate treatment.DesignMedical records were abstracted from 123 patients who were assessed as receiving inappropriate treatment and 66 patients who were assessed as receiving appropriate treatment but died within six months of intensive care unit (ICU) admission. We used mixed methods combining qualitative analysis of medical record documentation with multivariable analysis to examine the relationship between patient and communication factors and the receipt of inappropriate treatment, and present these within a conceptual model.SettingOne academic health system.ResultsMedical records revealed 21 themes pertaining to prognosis and factors influencing treatment aggressiveness. Four themes were independently associated with patients receiving inappropriate treatment according to physicians. When decision making was not guided by physicians (odds ratio [OR] 3.76, confidence interval [95% CI] 1.21-11.70) or was delayed by patient/family (OR 4.52, 95% CI 1.69-12.04), patients were more likely to receive inappropriate treatment. Documented communication about goals of care (OR 0.29, 95% CI 0.10-0.84) and patient's preferences driving decision making (OR 0.02, 95% CI 0.00-0.27) were associated with lower odds of receiving inappropriate treatment.ConclusionsMedical record documentation suggests that inappropriate treatment occurs in the setting of communication and decision-making patterns that may be amenable to intervention.

The US Preventive Services Task Force has issued a new draft guideline, with a "C" recommendation that men aged 55-69 yr should be informed about the benefits and harms of screening for prostate cancer, and offered prostate-specific antigen testing if they choose it. For men aged ≥70 yr, the recommendation remains "D", or "do not screen." This draft represents substantial progress in the right direction towards offering men a fair opportunity to discuss the risks and benefits of screening with their primary care providers. However, the evidence review underlying the draft remains fundamentally inadequate, leading to biased presentations of both benefits and harms of screening. The final guideline and future revisions should reflect formal engagement with subject matter experts to optimize the advise given to men and their physicians.

AimTo determine the prevalence of gastrointestinal neoplasia among dermatomyositis patients who underwent an esophagogastroduodenoscopy and/or colonoscopy.MethodsA cross-sectional study examining the results of upper endoscopy and colonoscopy in adults with dermatomyositis at an urban, university hospital over a ten year period was performed. Chart review was performed to confirm the diagnosis of dermatomyositis. Findings on endoscopy were collected and statistical analyses stratified by age and presence of symptoms were performed.ResultsAmong 373 adult patients identified through a code based search strategy, only 163 patients had dermatomyositis confirmed by chart review. Of the 47 patients who underwent upper endoscopy, two cases of Barrett's esophagus without dysplasia were identified and there were no cases of malignancy. Of the 67 patients who underwent colonoscopy, no cases of malignancy were identified and an adenoma was identified in 15% of cases. No significant differences were identified in the yield of endoscopy when stratified by age or presence of symptoms.ConclusionThe yield of endoscopy is low in patients with dermatomyositis and is likely similar to the general population; we identified no cases of malignancy. A code based search strategy is inaccurate for the diagnosis of dermatomyositis, calling into question the results of prior population-based studies. Larger studies with rigorously validated search strategies are necessary to understand the risk of gastrointestinal malignancy in patients with dermatomyositis.

ObjectiveThe Kidney Disease Outcome Quality Initiative and Fistula First Breakthrough Initiative call for the indiscriminate creation of arteriovenous fistulas (AVFs) over arteriovenous grafts (AVGs) without providing patient-specific criteria for vascular access selection. Although the U.S. AVF rate has increased dramatically, several reports have found that this singular focus on increasing AVFs has resulted in increased AVF nonmaturation/early failure and a high prevalence of catheter dependence. The objective of this study was to determine the appropriateness of vascular access procedures in clinical scenarios constructed with combinations of relevant factors potentially influencing outcomes.MethodsThe RAND/UCLA Appropriateness Method was used. Accordingly, a comprehensive literature search was performed and a synthesis of results compiled. The RAND/UCLA Appropriateness Method was applied to 2088 AVF and 1728 AVG clinical scenarios with varying patient characteristics. Eleven international vascular access experts rated the appropriateness of each scenario in two rounds. On the basis of the distribution of the panelists' scores, each scenario was determined to be appropriate, inappropriate, or indeterminate.ResultsPanelists achieved agreement in 2964 (77.7%) scenarios; 860 (41%) AVF and 588 (34%) AVG scenarios were scored appropriate, 686 (33%) AVF and 480 (28%) AVG scenarios were scored inappropriate, and 542 (26%) AVF and 660 (38%) AVG scenarios were indeterminate. Younger age, larger outflow vein diameter, normal or obese body mass index (vs morbidly obese), larger inflow artery diameter, and higher patient functional status were associated with appropriateness of AVF creation. Older age, dialysis dependence, and smaller vein size were associated with appropriateness of AVG creation. Gender, diabetes, and coronary artery disease were not associated with AVF or AVG appropriateness. Dialysis status was not associated with AVF appropriateness. Body mass index and functional status were not associated with AVG appropriateness. To simulate the surgeon's decision-making, scenarios were combined to create situations with the same patient characteristics and both AVF and AVG options for access. Of these 864 clinical situations, 311 (36%) were rated appropriate for AVG but inappropriate or indeterminate for AVF.ConclusionsThe results of this study indicate that patient-specific situations exist wherein AVG is as appropriate as or more appropriate than AVF. These results provide patient-specific recommendations for clinicians to optimize vascular access selection criteria, to standardize care, and to inform payers and policy. Indeterminate scenarios will guide future research.

Lung cancer screening with annual low-dose computed tomography reduces lung cancer death by 20-26%. However, potential harms of screening include false-positive results, procedures from false positives, procedural complications and failure to adhere to follow-up recommendations. In diverse, underserved populations, it is unknown if benefits of early lung cancer detection outweigh harms. We conducted a prospective observational study of lung cancer screening participants in an urban, safety-net institution from September 2014 to June 2020. We measured benefits of screening in terms of cancer diagnosis, stage, and treatment. We measured harms of screening by calculating false-positive rate, procedures as a result of false positive screens, procedural complications, and failure to follow-up with recommended care. Of patients with 3-year follow up, we measured these same outcomes in addition to compliance with annual screening. Of 1509 participants, 55.6% were African American, 35.2% White, 8.1% Hispanic, and 0.5% Asian. Screening resulted in cancer detection and treatment in 2.8%. False positive and procedure as a result of a false positive occurred in 9.2% and 0.8% of participants, respectively with no major complications from diagnostic procedures or treatment. Adherence to annual screening was low, 18.7%, 3.7%, and 0.4% at 1, 2, and 3 years after baseline screening respectively. Multidisciplinary lung cancer screening in a safety-net institution can successfully detect and treat lung cancer with few harms of false-positive screens, procedure after false-positive screens and major complications. However, adherence to annual screening is poor. [ABSTRACT FROM AUTHOR]

Abstract Background Inappropriate prescriptions can lead to adverse consequences for patients. It also imposes excessive cost on the patients, payers and health systems. The current study aimed at estimating the rate of inappropriate brain Magnetic Resonance Imaging (MRI) prescriptions and their financial burden in Iran. Methods Using systematic stratified sampling method, this cross-sectional study recruited 385 participants from three public teaching hospitals in Shiraz, Iran. Demographic information, questions related to brain MRI prescription and its indications checklist were collected using study-specific data collection tools. The completed indications checklist was compared to the appropriateness status table of indications and scenarios to detect the percent of the appropriateness of prescriptions. Results About 21 percentage of total brain MRI prescriptions are inappropriate. Previous treatment, number of referrals to physician, having other diagnostic tests and the applicant of MRI (P

Introduction: The use of multiparametric magnetic resonance imaging (MRI) to guide prostate biopsies has improved cancer detection rates, particularly for high-grade tumors. However, despite guidelines recommending biopsies for lesions with a Prostate Imaging-Reporting and Data System (PI-RADS) score ≥ 3, the clinical significance of PI-RADS 3 lesions remains uncertain. This uncertainty, coupled with the cost and potential complications of biopsies, underscores the need for more accurate risk stratification strategies to avoid unnecessary procedures. Prostate-specific antigen density (PSAD) and index lesion volume are emerging as potential contributors to improve risk assessment., Materials and Methods: This was a retrospective analysis of patients who had undergone an MRI-guided transrectal ultrasound (TRUS) prostate biopsy at a tertiary care institution. Patients with PI-RADS 3 lesions were included, and data on demographics, prostate-specific antigens (PSA), PSAD, lesion diameter, and pathology results were collected. The relationships between PSAD, lesion volume, and pathology outcomes were statistically analyzed., Results: Of the 213 patients included, 40 were diagnosed with prostate cancer. PSAD and PSAD x lesion diameter were significantly higher in the patients diagnosed with prostate cancer than those with benign lesions. Among the prostate cancer patients, clinically significant prostate cancer (csPCa) had a higher mean PSAD value than clinically insignificant prostate cancer (cisPCa). ROC analysis found PSAD x lesion diameter to have the highest discriminatory power for detecting csPCa., Discussion: MRI-guided biopsies offer targeted sampling but the clinical significance of PI-RADS 3 lesions remains uncertain. Index lesion volume and PSAD are promising adjunctive markers for risk assessment. Combining these factors could facilitate the avoidance of unnecessary biopsies and improve the detection of csPCa., Conclusion: Incorporating PSAD and index lesion volume into biopsy decision-making may enhance risk stratification, particularly for PI-RADS 3 lesions. Further research is needed to validate these findings and enhance the risk assessment strategies used in making decisions regarding prostate biopsy., (© 2024 Wiley Periodicals LLC.)

Study objective: Reduce inappropriate transthoracic echocardiograms (TTEs) using a series of Plan-Do-Study-Act (PDSA) quality improvement cycles. Design: Three PDSA cycles were designed with the first integrating a previously published decision support tool (DST) into the electronic TTE order, the second tailoring the DST to reflect the most common inappropriately ordered TTEs at our institution, and the third integrating direct clinician education. Setting: Malcom Randall Veterans Administration Medical Center, Gainesville, Florida, USA. Participants: Consecutive patients were studied using the database of all TTEs performed at our institution without regard for specific patient characteristics. Interventions: Three PDSA Cycles as described above. Main outcome measure: Reduction in inappropriate TTEs at our institution. Results: After implementing our DST during the first cycle, no difference in inappropriate TTEs was observed (relative risk [RR] 0.71, p = 0.12, 95 % confidence interval [CI] 0.46–1.09). After the second cycle, we observed a reduction in the proportion of inappropriate TTEs (RR = 0.69, p = 0.014, 95 % CI 0.5–0.94), however two of the four inappropriate TTEs targeted by the DST increased. Feedback gathered from clinicians in the third cycle showed significant knowledge gaps regarding appropriate use criteria for TTE. Conclusion(s): At our facility, implementation of a DST failed to substantially reduce inappropriate TTEs, even when adapted to facility-specific ordering patterns. Gaps in clinician knowledge about TTEs may have contributed to the inefficacy of our DST.

BACKGROUND: Overtreatment is a cause of preventable harm and waste in health care. Little is known about clinician perspectives on the problem. In this study, physicians were surveyed on the prevalence, causes, and implications of overtreatment. METHODS: 2,106 physicians from an online community composed of doctors from the American Medical Association (AMA) masterfile participated in a survey. The survey inquired about the extent of overutilization, as well as causes, solutions, and implications for health care. Main outcome measures included: percentage of unnecessary medical care, most commonly cited reasons of overtreatment, potential solutions, and responses regarding association of profit and overtreatment. FINDINGS: The response rate was 70.1%. Physicians reported that an interpolated median of 20.6% of overall medical care was unnecessary, including 22.0% of prescription medications, 24.9% of tests, and 11.1% of procedures. The most common cited reasons for overtreatment were fear of malpractice (84.7%), patient pressure/request (59.0%), and difficulty accessing medical records (38.2%). Potential solutions identified were training residents on appropriateness criteria (55.2%), easy access to outside health records (52.0%), and more practice guidelines (51.5%). Most respondents (70.8%) believed that physicians are more likely to perform unnecessary procedures when they profit from them. Most respondents believed that de-emphasizing fee-for-service physician compensation would reduce health care utilization and costs. CONCLUSION: From the physician perspective, overtreatment is common. Efforts to address the problem should consider the causes and solutions offered by physicians.

BackgroundOveruse of clinical laboratory testing in the inpatient setting is a common problem. The objective of this project was to develop an inexpensive and easily implemented intervention to promote rational laboratory use without compromising resident education or patient care.MethodsThe study comprised of a cluster-randomized, controlled trial to assess the impact of a multifaceted intervention of education, guideline development, elimination of recurring laboratory orders, unbundling of laboratory panels, and redesign of the daily progress note on laboratory test ordering. The population included all patients hospitalized "general medicine" was duplicated during 2 consecutive months on a general medicine teaching service within a 999-bed tertiary care hospital in Boston, Massachusetts. The primary outcome was the total number of commonly used laboratory tests per patient day during 2 months in 2008. Secondary outcomes included a subgroup analysis of each individual test per patient day, adverse events, and resident and nursing satisfaction.ResultsA total of 5392 patient days were captured. The intervention produced a 9% decrease in aggregate laboratory use (rate ratio, 0.91; P = .021; 95% confidence interval, 0.84-0.98). Six instances of delayed diagnosis of acute kidney injury and 11 near misses were reported in the intervention arm.ConclusionsA bundled educational and administrative intervention promoting rational ordering of laboratory tests on a single academic general medicine service led to a modest but significant decrease in laboratory use. To our knowledge, this was the first study to examine the daily progress note as a tool to limit excessive test ordering. Unadjudicated near misses and possible harm were reported with this intervention. This finding warrants further study.

BACKGROUND: Overutilization of advanced diagnostic imaging modalities strains health care systems, especially in resource limited setups. The aim of this study is to identify magnitude of inappropriate Head Computed Tomography scans at Tikur Anbessa Specialized Hospital. METHODS: Retrospective cross-sectional study was conducted at Tikur Anbessa Specialized Hospital, Radiology department, among patients getting Head Computed Tomography examinations in the period of August 2018-November 2018. Appropriateness of each scan was assessed using the American College of Radiology Appropriateness Criteria. RESULT: Of the 443 Head Computed Tomography scans assessed, 61.6% were done for male patients and the mean age of patients scanned is 35. Children younger than 14yrs of age constituted 17.2%. No contrast was used in 63.9% of the scans and 64.3% were initial imaging with no prior study for similar indication. Out of the scans evaluated, 11.7% were inappropriate. Headache (38.5%), Seizure (23.1%) and Head trauma (23.1%) were the commonest indications for inappropriate scan. Scans done for cerebrovascular disease were 240 times more likely to be appropriate. Large number of inappropriate scans were requested from central triage (33.3%) and adult emergency (26.2%). Pediatric department requested inapproprieate scans in 11.9% of the cases. Residents requested majority of inappropriate scans (82.3%). Inappropriateness was associated with use of contrast agent and having only incidental outcomes. CONCLUSION: A large number of inappropriate Head Computed Tomography scans are being done. Mechanisms such as preauthorization by radiologists, increasing awareness by medical students, physicians, radiology residents and radiologists and preparing customized imaging appropriateness guidelines should be implemented.

Objective: Central nervous system (CNS) infection poses a diagnostic challenge especially in elderly patients who frequently exhibit atypical symptoms. Our study aimed to identify patients with a low risk of CNS infection, in whom lumbar puncture (LP) could be avoided., Methods: Observational study of consecutive adult patients who underwent a LP in the emergency room (ER) of Hospital Universitari Vall d'Hebron between January 2017 and December 2021. We performed a univariate and multivariate analysis to identify factors associated with non-CNS infection. These factors were used to create a combined variable, and its diagnostic positive predictive value and specificity to detect patients without CNS infections were calculated., Results: We included 489 patients of which 77 (15.7%) were diagnosed with CNS infection. Median age was 62 years (IQR 41-78) and 240 (49.1%) were male. In the multivariate analysis, variables associated with non-CNS infection were female sex (OR 1.89; 95% CI 1.12-3.20), age older than 80 years (OR 3.14; 95% CI 1.20-8.19), previous cognitive impairment (OR 3.91; 95% CI 1.18-13.01), and clinical presentation without meningitis triad (fever, headache and neck stiffness) (OR 4.12; 95% CI 1.72-9.85). A composite variable encompassing age older than 80, cognitive impairment, and the absence of the meningitis triad was used as a diagnostic tool to identify patients with non-CNS infection, exhibiting a 98% positive predictive value and 99% specificity., Conclusions: This study identifies factors associated with a low risk of CNS infection. Thus, a more precise clinical approach could help clinicians to detect patients who would not benefit from a LP., (Copyright © 2024 Elsevier España, S.L.U. All rights reserved.)

Background: A limited transthoracic echocardiogram (TTE) can be an appropriate, lower-cost substitute for a full TTE. We assessed the impact of an electronic health record alternative alert promoting the adoption of limited TTEs on the ordering practices of cardiology clinicians and primary care providers and captured their perspectives on the initiative., Methods: The alert was deployed in a cardiology clinic and 4 primary care clinics at an academic medical center. The alert provided clinical guidance on the appropriate use of limited TTEs when a clinician selected a full TTE order. We used logistic regression to estimate the change in the proportion of limited versus full TTEs ordered between the baseline and intervention periods in clinics with and without the alert. We also conducted interviews with 24 clinicians (5 cardiologists and 19 primary care providers) to identify implementation barriers and facilitators., Results: Cardiology clinicians ordered 10 654 and 3761 TTEs during the baseline and intervention periods, respectively, for 9100 patients. Primary care providers ordered 723 and 617 TTEs during the baseline and intervention periods for 1273 patients. The model estimated that the percentage of limited TTEs ordered increased by 16.1±2.3 percentage points ( P <0.0001) in the cardiology clinic with the alert and by 13.2±1.5 percentage points ( P <0.0001) in the primary care clinics with the alert from baseline to post-intervention. Ordering practices did not change in the cardiology (0.7±0.6 percentage points; P =0.24) or primary care (0.7±1.0 percentage points; P =0.52) clinics without the alert. Clinicians viewed the alert as acceptable. Cardiologists appreciated that the alert was concise, whereas primary care providers wanted more information from the alert., Conclusions: An alternative alert providing clinical guidance on the use of limited TTEs at the point of care increased the selection of this lower-cost test in cardiology and primary care clinics. Perspectives on the alert differed between specialists and nonspecialists, highlighting the importance of tailoring intervention design to clinical expertise., Competing Interests: Dr Levin reports consulting fees from AliveCor.

Background: Physicians' choice of appropriate tests in the diagnostic process is crucial for patient safety. The increased use of medical imaging has raised concerns about its potential overuse. How appropriately medical students order diagnostic tests is unknown. We explored their ordering behavior of diagnostic imaging during a simulated first day of residency., Methods: In total, 492 undergraduate medical students participated in the simulation. After history taking with simulated patients, the students used an electronic system for requesting diagnostic tests. The analysis focused on 16 patient cases, each managed by at least 50 students. We calculated the total number of ordered images and unnecessary radiation exposure in millisievert per patient and performed one sample t-tests (one tailed) with an expected mean of zero on a Bonferroni-corrected alpha level of 0.003 for the independent variable of unnecessary radiation exposure., Results: Unnecessary diagnostic imaging was ordered across all patient cases. Ultrasound, especially abdominal ultrasound, X-rays of the thorax, and abdominal CTs were notably overused in 90.9%, 80.0%, and 69.2% of all patient cases, respectively. Unnecessary requests of imaging related to radiation resulted in radiation over-exposure for nearly all patients, with 37.5% of all patients being exposed to a significant radiation overdose on average., Conclusion: Medical students' overuse of diagnostic imaging can be explained by patient-related factors like anxiety and medical factors like missing clinical information leading to cognitive biases in patient workup. This suggests the need for interventions to improve students' clinical decision-making and reduce cognitive biases. Investigating student-specific factors being associated with overuse of diagnostic imaging would be of additional interest., (© 2024. The Author(s).)

Introduction: With increasing healthcare costs, it is important to quantify the number of total knee arthroplasty (TKA) patients who have MRIs that are not considered clinically necessary. The purpose of this study was to determine the number of unnecessary preconsultation MRIs done among TKA patients at our institution., Methods: Eight hundred and sixty-nine patients who underwent a primary TKA were identified. Review of medical records and imaging results was conducted to determine which patients had received preconsult MRIs and whether they were necessary or unnecessary., Results: Of the 869 TKA, 177 (20.4%) presented with a preconsultation MRI, of which, 112 met the study inclusion criteria. Of the 112 MRIs, 18 (20.7%) were done without radiographic imaging, and 69 (79.3%) were completed after radiographically evident moderate-to-severe arthritis. Overall, 87 MRIs (10.0%) were deemed clinically unnecessary., Conclusions: Referring physicians are overusing MRIs before consultation with an orthopaedic surgeon. The 87 patients who had unnecessary MRIs at our institution over a one-year period represented a cost of $20,706. Extrapolating that number to the scale of patients affected by arthritis each year is potentially a staggering amount of money. Evidence-based guidelines should be put into place to optimize healthcare utilization., (Copyright © 2024 The Authors.

Background: Several concerns have been raised over the past several years about the potential for overuse of vascular interventions for peripheral artery disease. These interventions can have serious complications, including limb loss. Given that the natural history of intermittent claudication rarely includes limb loss, it is critically important that interventions to treat it have appropriate indications., Methods: To address this matter, the Society for Vascular Surgery published an appropriate use criteria (AUC) document for the management of intermittent claudication in 2022. Using the rigorously studied University of California Los Angeles RAND Appropriateness Method, the rating panel assessed the appropriateness of 2,280 scenarios for [1] the initial management and [2] the management after a failed trial of exercise therapy., Results: The findings of the rating panel included that medical management and exercise therapy are appropriate initial management in all scenarios. There were several scenarios in which revascularization was also considered appropriate, mainly influenced by severity of physical limitations and favorable lesion characteristics. When considering management after a failed trial of exercise, guiding principles cited by the rating panel included durability of intervention, smoking cessation, and evidence of prior good-faith effort at exercise therapy. There were many scenarios which were indeterminate. With respect to the infrapopliteal segment, the rating panelists unanimously agreed to forgo individual scenario ratings, since they deemed the risks outweigh the benefits in all cases., Conclusions: The Society for Vascular Surgery (SVS) AUC for intermittent claudication represents an important effort to identify and reduce overuse. There are several considerations for how they should be used. The simplest application is by practicing clinicians, at the bedside, as they engage in shared decision-making with patients. The matter of their use by payors is more complex. Ideally, decisions on how to best use AUC require additional study of their performance before they are used by payors for anything. Finally, these AUC have identified a myriad of areas where evidence is lacking. The AUC provide important targets for future research to improve the care of patients with intermittent claudication., (Copyright © 2023 Elsevier Inc. All rights reserved.)

Introduction: Wearable cardioverter-defibrillators (WCD) have emerged as a valuable tool in the management of patients at risk for life-threatening arrhythmias. These devices offer a non-invasive and temporary solution, providing continuous monitoring and the potential for prompt defibrillation when needed. In this study, we explore the use of WCD and evaluate arrhythmic events through comprehensive monitoring., Methods: From November 2022 to May 2024, we conducted an outpatient follow-up of 41 patients receiving WCD. Regular check-ups, remote monitoring and comprehensive echocardiography were performed to optimise a tailored therapy., Results: The average age of the patients was 59.2.4±16.5 years, with 78% being male. Among the cohort, 54% had hypertension, 41% were smokers and 66% had dyslipidaemia, while 27% were diabetic. WCD was assigned according to the Italian Association of Hospital Cardiologists position paper focussing on the appropriate use of WCD and European Society of Cardiology guidelines on ventricular arrhythmias and the prevention of sudden cardiac death: 24 (58%) patients had a de novo diagnosis of heart failure with reduced ejection fraction, 11 (27%) patients had a recent acute coronary syndrome and ejection fraction <35%, 3 (7%) patients had a cardiac electronic device extraction and 3 (7%) patients had myocarditis with features of electrical instability. The average follow-up was 62±38 days according to specific aetiology, with a daily wearing time of 22.7±1.3 hours. No device interventions were recorded. At the end of the follow-up period, 15 patients still required an implantable cardioverter-defibrillator (ICD). Among these, 12 patients (29%) underwent ICD implantation. Two patients (5%) declined the procedure., Conclusions: The use of WCD for patients at high risk of arrhythmias allowed to optimise therapy and limit the indications for ICD. Inappropriate implantation of ICD was avoided in 69% of patients who received WCD. The device showed a good safety profile, low incidence of device interventions and adequate patients' adherence to WCD use., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background: Brain magnetic resonance imaging (MRI) is mandatory or highly recommended in many pediatric endocrinological conditions to detect causative anatomic anomalies and rule out neoplastic lesions. However, MRI can also show findings associated with the underlying clinical condition, as well as unrelated "incidentalomas". These latter findings are often abnormalities with a high incidence in the general population for which there is no clear literature regarding their management, especially in pediatric patients. The present study aimed to evaluate the number of unnecessary performed MRIs in pediatric endocrinology., Methods: Retrospective analysis on 584 MRI scans performed in 414 patients (254 growth hormone deficiency, 41 other causes of short stature, 116 central precocious puberty)., Results: The MRI scans were completely normal in 67% of the individuals, and the prevalence of individuals who underwent more than one MRI was 18%, with no significant differences among the groups. The overall prevalence of incidentalomas was 17%. Among 170 repeated MRI scans, 147 (86%) were not required according to a dedicated protocol. Only five patients (four GHD, one Noonan) correctly repeated the MRI. All the repeated MRI scans did not reveal any progression in the findings. If we include the MRIs performed in cases of OCSS other than Noonan syndrome (n=32) and girls with CPP older than 6 years (n=89), an additional 121 MRIs could have been avoided, leading to a total number of unnecessary MRIs to 268 (46%)., Conclusions: Only a few specific neuroimaging findings in endocrinologic pediatric patients warrant further investigation, while too often repeated imaging is carried out unnecessarily. We advocate the importance of guidelines to reduce costs for both the healthcare system and patients' families, as well as to alleviate physical and psychological distress for patients and caregivers., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

UnlabelledWe investigated the value of routine laboratory testing for identifying underlying causes in older men diagnosed with osteoporosis. Most osteoporotic and nonosteoporotic men had ≥1 laboratory abnormality. Few individual laboratory abnormalities were more common in osteoporotic men. The benefit of routine laboratory testing in older osteoporotic men may be low.IntroductionTo evaluate the utility of recommended laboratory testing to identify secondary causes in older men with osteoporosis, we examined prevalence of laboratory abnormalities in older men with and without osteoporosis.MethodsOne thousand five hundred seventy-two men aged ≥65 years in the Osteoporotic Fractures in Men study completed bone mineral density (BMD) testing and a battery of laboratory measures, including serum calcium, phosphorus, alkaline phosphatase, parathyroid hormone (PTH), thyroid-stimulating hormone (TSH), 25-OH vitamin D, total testosterone, spot urine calcium/creatinine ratio, spot urine albumin/creatinine ratio, creatinine-derived estimated glomerular filtration rate, 24-h urine calcium, and 24-h urine free cortisol. Using cross-sectional analyses, we calculated prevalence ratios (PRs) and 95 % confidence intervals (CI) for the association of any and specific laboratory abnormalities with osteoporosis and the number of men with osteoporosis needed to test to identify one additional laboratory abnormality compared to testing men without osteoporosis.ResultsApproximately 60 % of men had ≥1 laboratory abnormality in both men with and without osteoporosis. Among individual tests, only vitamin D insufficiency (PR, 1.13; 95 % CI, 1.05-1.22) and high alkaline phosphatase (PR, 3.05; 95 % CI, 1.52-6.11) were more likely in men with osteoporosis. Hypercortisolism and hyperthyroidism were uncommon and not significantly more frequent in men with osteoporosis. No osteoporotic men had hypercalciuria.ConclusionsThough most of these older men had ≥1 laboratory abnormality, few routinely recommended individual tests were more common in men with osteoporosis than in those without osteoporosis. Possibly excepting vitamin D and alkaline phosphatase, benefit of routine laboratory testing to identify possible secondary causes in older osteoporotic men appears low. Results may not be generalizable to younger men or to older men in whom history and exam findings raise clinical suspicion for a secondary cause of osteoporosis.
