Outpatient total hip arthroplasty (THA) is a safe option for select patients. The purpose of this study was to analyze a national database and understand risk factors that lead to unplanned early readmission and reoperation after outpatient THA. The National Surgical Quality Improvement Program database was used to collect outpatient THAs performed from 2013 to 2020. The outpatient setting was defined as a reported hospital length of stay of 23 hours or less. Data variables collected included patient demographics, medical comorbidities, American Society of Anesthesiologists classification, functional status, preoperative laboratory values, National Surgical Quality Improvement Program morbidity probability, and 30-day readmissions and reoperations. A total of 15,055 patients underwent out-patient THA. Mean age was 62.6 years, and 52.1% of patients were men. Mean body mass index was 29.3 kg/m 2 . The overall rate of readmission was 1.8%, and the reoperation rate was 1.0%. Patients with a 30-day re-admission were older ( P P P P =.01). Patients with a 30-day reoperation had higher body mass index ( P P P P P P P Orthopedics . 202x;4x(x):xx–xx.]

The purpose of this study was to evaluate the impact of opioid-limiting legislation on perioperative opioid prescriptions in total knee arthroplasty. The hypothesis was that opioid legislation has reduced opioid prescription filling above levels anticipated by national trends. This study retrospectively evaluated opioid prescription filling for all patients undergoing total knee arthroplasty in a commercially available insurance database between 2010 and 2018 (n=1,068,764). Initial discharge and 90-day cumulative oxycodone 5-mg equivalents filled were tabulated. Opioid prescription filling was evaluated over time and between states with and without opioid-limiting legislation using analysis of variance and multivariable linear and logistic regression. States with and without opioid legislation had significant reductions in initial and cumulative opioid prescription filling volume (all P Orthopedics. 2023;46(3):142–150.]

Perioperative advancements have made outpatient primary total hip arthroplasty (THA) a viable option for patients. This study evaluated the feasibility of expedited discharge after revision THA and compared 30-day outcomes to patients who had prolonged inpatient hospitalizations. The authors hypothesized that expedited discharge would not result in inferior 30-day outcomes.Aseptic revision THAs in a national database were reviewed from 2013 to 2020. THAs were stratified by hospital length of stay (LOS) more or less than 24 hours. Demographics, comorbidities, preoperative laboratory values, American Society of Anesthesiology (ASA) scores, operative times, components revised, 30-day readmissions, and reoperations were compared. Multivariable analyses evaluated predictors of discharge prior to 24 hours, 30-day readmissions, and reoperations. Of 17,044 aseptic revision THAs, 211 were discharged within 24 hours.Accelerated discharge patients were younger, mean age 63 years (range, 20-92) versus 66 years (range, 18-94) (P.01) had lower body mass index, mean 28.7 (range, 18.3-46.4) versus 29.9 (range, 17.3-52.5) (P = .01), and ASA scores (ASA, 1-2; 40.4-57.8%) (P.01). Components revised had no association with LOS (P = .39); however, operative times were shorter and mean 100 minutes (range, 35-369) versus 139 minutes (range, 24-962) (P.01) in accelerated discharge patients. Accelerated discharge patients had lower readmission rates (P.01) but no difference in reoperation rates (P = .06).Discharge less than 24 hours after revision THA is a feasible option for the correct patient and further efforts to decrease LOS should be evaluated.

The current gold standard for treating chronic Periprosthetic Joint Infection (PJI) is a 2-stage revision arthroplasty. There has been little investigation into what specific patient and operative factors may be able to predict higher costs of this treatment.An institutional electronic health record database was retrospectively queried for patients who developed a PJI after a total hip arthroplasty, and underwent removal of the prosthesis and implantation of an antibiotic-impregnated articulating hip cement spacer. Patient demographics, surgical variables, hospital readmissions, emergency department visits, and post-operative complications were collected. Total costs were captured through an internal accounting database through 2 years post-operatively. Negative binomial regressions were utilized for multivariable analyses. A total of 55 hips with PJI were available for cost analyses.A comorbidity index score was associated with a 70% increase (Odds Ratio (OR): 1.7 [1.18-2.5], P = .003) in total costs at 2-years. Illicit drug use was associated with a 70% increase in costs at 1-year post-operatively (OR 1.7 [1.18-2.5], P = .003). Metal-on-poly liners were associated with a 22% decrease in cost at 2-years post-operatively when compared to Cement-on-Bone articulating spacers, and Metal-on-poly -constrained liners accounted for 38% lower costs at 1-year (OR 0.62 [0.44-0.87], P = .004). Use of an intraoperative extended trochanteric osteotomy was associated with a 46 and 61% increase in cost at 1-year (OR 1.46 [1.14-1.89]) and 2-years (OR 1.61 [1.26-2.07], P.001) post-operatively.Age, comorbidity index score, drug use, and extended trochanteric osteotomy were associated with increased costs of PJI treatment. This may be used to improve reimbursement models and target areas of cost savings.

Cutibacterium spp. is an emerging pathogen in total hip arthroplasty (THA) that is not well evaluated in the literature. This study reported on the presentation and management of THA complicated by positive intraoperative Cutibacterium cultures.This is a retrospective review of 27 revision THAs with positive monomicrobial intraoperative Cutibacterium cultures from 2014 to 2020 at one academic center. These patients were divided into two cohorts based on meeting Musculoskeletal Infection Society (MSIS) criteria for prosthetic joint infections (PJI). Patient demographics, preoperative labs, and hip aspirate results were collected. Procedure performed, postoperative antibiotic regimens, and repeat infections were recorded. Data were compared with univariate analysis.Nine of the 27 patients preoperatively met MSIS criteria for PJI. Patients with positive MSIS criteria had significantly higher median synovial cell count (P = .048) and neutrophil percentage in a preoperative aspirate (P = .050). Eight patients with positive MSIS criteria received six weeks of postoperative antibiotics compared to two patients with negative criteria. Two patients with positive MSIS criteria had a postoperative infection that required further surgical intervention. Four patients with negative criteria who required further surgical intervention did not receive postoperative antibiotics after initial revision.While often categorized as a contaminant, Cutibacterium is an increasingly recognized pathogen in THA. Cutibacterium can often present with normal serology, which may result in misdiagnosis as aseptic THA failure. Without the administration of postoperative antibiotics after positive cultures, there is a risk for persistent infection requiring further surgical intervention.

The volume of outpatient total knee arthroplasty (TKA) has increased with advances in perioperative protocols, patient selection, and recent policy changes regarding insurance authorization. This study analyzed 30-day outcomes from a national database to better understand risk factors for delayed discharge (length of stay [LOS] ≥1), readmission, and reoperation after outpatient TKA.The National Surgical Quality Improvement Program (NSQIP) database was utilized to collect TKA (CPT 27447) billed as outpatient surgery performed from 2013 to 2018. Patient demographics, comorbidities, and short-term outcomes were collected and compared in LOS 0 versus LOS ≥1 cohorts. Subgroup analysis was completed for TKA performed in 2018, after the Center for Medicare Services removal of TKA from the inpatient-only list.A total of 13,669 patients had outpatient TKA performed from 2013 to 2018. Most patients had LOS ≥1 day (77.1%). The LOS 0 cohort demonstrated a lower 30-day readmission rate (1.8%) compared to LOS ≥1 (2.8%), P.01. Both groups demonstrated a low 30-day reoperation rate, LOS 0 (0.7%) and LOS ≥1 (1.1%), P = .05. Regression analysis demonstrated risk factors for LOS ≥1 day included COPD, ASA ≥3, age75, and BMI35 kg/mRisk factors for LOS ≥1 day include age75, ASA ≥3, BMI35 kg/m

The current American Association of Hip and Knee Surgeons (AAHKS) guidelines recommend preoperative weight loss before total knee arthroplasty (TKA) in patients with body mass index (BMI) ≥40 kg/mThis is a retrospective review of 3058 primary TKAs at an academic institution from 2015 to 2019. BMI was collected on the day of surgery. Preoperative and postoperative BMI at 6 months and 1 year were also obtained. BMI change of ≥5% was considered clinically significant. Mean follow-up was 3.2 years. Patient demographics, acute postoperative outcomes, and all-cause revisions were compared between patients who gained, lost, or maintained weight using univariate and multivariable analyses.Preoperative weight loss was predictive of postoperative weight gain (P.001), and preoperative weight gain was predictive of postoperative weight loss (P.001). Cox regression analysis revealed that ≥5% BMI loss preoperatively increased risk for all-cause revisions (P = .030), while ≥5% BMI gain postoperatively increased risk for prosthetic joint infections (P = .016). Patients who lost significant weight both before and after surgery had the highest risk for all-cause revisions (P = .022).Weight gain postoperatively was associated with inferior outcomes. Significant weight loss before surgery led to a "rebound" in weight gain, and independently increased risk for all-cause revision. Therefore, current recommendations for weight loss before TKA in morbidly obese patients should be re-evaluated.

Aims In the last decade, perioperative advancements have expanded the use of outpatient primary total knee arthroplasty (TKA). Despite this, there remains limited data on expedited discharge after revision TKA. This study compared 30-day readmissions and reoperations in patients undergoing revision TKA with a hospital stay greater or less than 24 hours. The authors hypothesized that expedited discharge in select patients would not be associated with increased 30-day readmissions and reoperations. Methods Aseptic revision TKAs in the National Surgical Quality Improvement Program database were reviewed from 2013 to 2020. TKAs were stratified by length of hospital stay (greater or less than 24 hours). Patient demographic details, medical comorbidities, American Society of Anesthesiologists (ASA) grade, operating time, components revised, 30-day readmissions, and reoperations were compared. Multivariate analysis evaluated predictors of discharge prior to 24 hours, 30-day readmission, and reoperation. Results Of 21,610 aseptic revision TKAs evaluated, 530 were discharged within 24 hours. Short-stay patients were younger (63.1 years (49 to 78) vs 65.1 years (18 to 94)), with lower BMI (32.3 kg/m2 (17 to 47) vs 33.6 kg/m2 (19 to 54) and lower ASA grades. Diabetes, chronic obstructive pulmonary disease, hypertension, and cancer were all associated with a hospital stay over 24 hours. Single component revisions (56.8% (n = 301) vs 32.4% (n = 6,823)), and shorter mean operating time (89.7 minutes (25 to 275) vs 130.2 minutes (30 to 517)) were associated with accelerated discharge. Accelerated discharge was not associated with 30-day readmission and reoperation. Conclusion Accelerated discharge after revision TKA did not increase short-term complications, readmissions, or reoperations. Further efforts to decrease hospital stays in this setting should be evaluated. Cite this article: Bone Joint J 2022;104-B(12):1323–1328.

Total hip arthroplasty (THA) in young patients has varying results, and some reports show inferior results when compared with those of older patients. This study evaluated the outcomes of contemporary uncemented THA in patients 45 years or younger. This was a retrospective review from 2003 to 2015 at an academic institution. Three hundred one uncemented THAs in 232 patients 45 years or younger were evaluated. All patients had a minimum follow-up of 5 years. Ninety-day complications, survivorship free of revision, and dislocations were evaluated. Mean age was 35.7 years, 43.1% of patients were women, and mean follow-up was 9.3 years. Ninety-day complications included 26 emergency department visits, 11 readmissions, 3 revisions, and 3 dislocations. The rate of 10-year survivorship free of revision was 85.5%, and the rate of 10-year survivorship free of aseptic revision was 87.7%. Excluding metal-on-metal (MOM) THAs, 10-year aseptic survivorship was 93.3%. The most common reasons for revision were adverse local tissue reaction after MOM THA (16 hips) and periprosthetic joint infection (6 hips). In a multivariable logistic regression model, sickle cell disease (SCD) and conversion THA were associated with 90-day readmissions. Both MOM THA and SCD were associated with revision ( P Orthopedics . 2023;46(1):e45–e51.]

Girdlestone resection arthroplasty is a salvage procedure for hip periprosthetic joint infection (PJI) that controls infection and reduces chronic pain, but may result in limited post-operative joint function. The aim of this study was to assess physical function and mental health after Girdlestone.This was a multicenter, prospective study evaluating patients with Girdlestone. The Prosthesis Evaluation Questionnaire (PEQ) and PROMIS Global Physical Health and Mental Health surveys were administered post-operatively via telephone. The PEQ consists of four scales (i.e., ambulation, frustration, perceived response, social burden) with scores ranging from 0 to 10. The PROMIS measures generated T scores (mean: 50, Standard Deviation (SD): 10) that enable comparison to the general population.Thirty-five patients completed all surveys. The average time from procedure to survey completion was 6 years (range, 1 to 20). The median scores for the ambulation, frustration, perceived response, and social burden scales of the PEQ were 0.0 [IQR: 0-4.1], 6.0 [3.0-9.3], 9.0 [7.2-10.0], and 7.5 [4.3-9.5]. The median raw scores of the PROMIS Global Physical Health and Mental Health were 11.91 [IQR: 9-14] and 14.0 [10.0-16.0]. These corresponded to average T-scores of 39.7 (Standard Error (SE): 4.3) for physical health and 46.1 (SE: 3.8) for mental health, which were 10.3 points and 3.9 points below the average score in the United States general population, respectively.Girdlestone can have a substantial negative impact on physical function; however, mental health and social interaction may be only moderately affected. These outcomes can be used to guide patient expectations, as this procedure may be necessary in certain salvage scenarios.

Aims Periprosthetic joint infections (PJIs) are among the most devastating complications after joint arthroplasty. There is limited evidence on the efficacy of different antiseptic solutions on reducing biofilm burden. The purpose of the present study was to test the efficacy of different antiseptic solutions against clinically relevant microorganisms in biofilm. Methods We conducted an in vitro study examining the efficacy of several antiseptic solutions against clinically relevant microorganisms. We tested antiseptic irrigants against nascent (four-hour) and mature (three-day) single-species biofilm created in vitro using a drip-flow reactor model. Results With regard to irrigant efficacy against biofilms, Povidone-iodine treatment resulted in greater reductions in nascent MRSA biofilms (logarithmic reduction (LR) = 3.12; p < 0.001) compared to other solutions. Bactisure treatment had the greatest reduction of mature Pseudomonas aeruginosa biofilms (LR = 1.94; p = 0.032) and a larger reduction than Vashe or Irrisept for mature Staphylococcus epidermidis biofilms (LR = 2.12; p = 0.025). Pooled data for all biofilms tested resulted in Bactisure and Povidone-iodine with significantly greater reductions compared to Vashe, Prontosan, and Irrisept solutions (p < 0.001). Conclusion Treatment failure in PJI is often due to failure to clear the biofilm; antiseptics are often used as an adjunct to biofilm clearance. We tested irrigants against clinically relevant microorganisms in biofilm in vitro and showed significant differences in efficacy among the different solutions. Further clinical outcome data is necessary to determine whether these solutions can impact PJI outcome in vivo. Cite this article: Bone Joint J 2021;103-B(5):908–915.

INTRODUCTION Outpatient total knee arthroplasty (TKA) is increasingly common in the setting of early-recovery protocols, value-based care, and removal from the inpatient-only list by the Centers for Medicare & Medicaid Services. Given the established racial disparities that exist in different aspects of total joint arthroplasty, we aimed to investigate whether racial and ethnic disparities exist in outpatient compared with inpatient TKA. METHODS This was a retrospective cohort study using the American College of Surgeons National Surgical Quality Improvement Program. We queried TKAs done in 2018. Demographics, inpatient (≥2 midnights) versus outpatient (≤1 midnight) status, comorbidities, and perioperative events/complications were recorded. We analyzed differences between racial/ethnic groups and predictors of inpatient versus outpatient surgery, and outcomes. RESULTS A total of 54,582 patients were included (83.2% Caucasian, 9.2% African American [AA], 4.5% Hispanic, 2.4% Asian, and 0.6% Native American). AA had the highest mean body mass index, American Society of Anesthesiologists score, and comorbidity burden. AA had the lowest rate of outpatient TKA (18.3%) and Asians the highest rate of outpatient TKA (31.4%, P < 0.0001). AA had the highest postoperative transfusion rate (1.8%, P < 0.0001) and highest rate of discharge to acute rehab (8.4%). Asians had the highest rate of postoperative cardiac arrest and urinary tract infection. AA had the highest rate of acute kidney injury within 30 days. Regression analyses revealed that AAs were more likely to undergo inpatient surgery (odds ratio [OR], 2.58; confidence interval [CI], 1.57-4.23; P = 0.001) and discharge to rehab/skilled nursing facility [SNF] (OR, 2.86; CI, 1.66-4.92; P = 0.001). Asian patients were more likely to undergo outpatient surgery (OR, 2.48, CI, 1.47-4.18, P = 0.001) and discharged to rehab/SNF (OR, 2.41, CI, 1.36-4.25, P = 0.001). Caucasians were more likely to undergo outpatient surgery (OR, 1.62, CI, 1.34-1.97, P = 0.001) and less likely discharged to rehab/SNF (OR, 0.73, CI, 0.60-0.88, P = 0.001). When controlling for comorbidities, race was not an independent risk factor for 30-day complications or inpatient versus outpatient surgery. DISCUSSION Differences in indications for outpatient TKA between races/ethnicities seem to be highly associated with comorbidity burden and preoperative baseline differences, not race alone. Appropriate patient optimization for either outpatient or inpatient TKA may reduce disparities between groups in either care setting.

Prosthetic joint infections (PJIs) are among the most devastating complications after joint replacement. There is limited evidence regarding the efficacy of different antiseptic solutions in reducing planktonic microorganism burden. The purpose of this study was to test the efficacy of different antiseptic solutions against clinically relevant planktonic microorganisms. We designed an experiment examining the efficacy of several antiseptic solutions against clinically relevant planktonic microorganisms in vitro. Regarding planktonic microorganisms, povidone-iodine had 99.9% or greater reduction for all microorganisms tested except for methicillin-resistant Staphylococcus aureus, which was reduced by 60.44%. Irrisept (Irrimax Corp) had 99.9% or greater reduction for all microorganisms except Staphylococcus epidermidis (98.31%) and Enterococcus faecalis (48.61%). Bactisure (Zimmer Surgical Inc) had 99.9% or greater reduction for all microorganisms tested. Various measures exist for PJI prevention, one of which is intraoperative irrigation. We tested irrigants against clinically relevant planktonic microorganisms in vitro and found significant differences in efficacy among them. Further clinical outcome data are necessary to determine whether these solutions can impact PJI in vivo. [ Orthopedics . 2022;45(2):122–127.]

Robotic-assisted knee arthroplasty has become increasingly commercially available as both technology developers and surgeons attempt to address specific limitations of conventional jig-based alignment techniques in order to improve resection accuracy and precision. Semi-active and passive systems predominate in the North American and European markets and can provide surgeons additional instruments for intraoperative calibration and balance assessment or directly assist in performing personalized resections. Recently published and ongoing clinical investigations seek to determine if robotic assistance may result in improved radiographic or clinical outcomes for patients undergoing either unicompartmental or total knee arthroplasty. A number of studies evaluating conventional and robotic-assisted knee arthroplasty did not identify significant radiographic or clinical outcome differences, though heterogeneity in robotic system design and application may limit the generalization of focused studies. Conversely, some studies that identified significant differences noted that robotic-assisted knee arthroplasty may be associated with fewer alignment outliers as well as increased surgical time—at least initially for unfamiliar surgeons. Further limitations include limited follow-up for newer systems on the market as well as the associated variety of arthroplasty implants and authors’ surgical techniques. Future studies will help surgeons and patients determine if intraoperative robotic assistance may be beneficial in total knee arthroplasty.

There is limited evidence on sociodemographic differences in osteoarthritis management, particularly in non-African American (AA) minorities. We sought to identify differences in imaging modalities, administration of intra-articular injections, and total joint arthroplasty (TJA) between racial/ethnic groups.We retrospectively reviewed patients presenting to outpatient clinics with a diagnosis of hip or knee osteoarthritis from January 2013 to March 2020 at a tertiary center. Univariate analyses compared differences between groups. Multivariate logistic regression analyses determined sociodemographic predictors of imaging workup and treatment.In total, 105,873 patients were included. There were 74,769 (70.6%) Caucasian, 27,117 (25.6%) AA, 1,878 (1.8%) Hispanic, 1,479 (1.4%) Asian, and 630 (0.6%) Native American patients. Multivariate analyses demonstrated that AAs had decreased odds of undergoing a knee magnetic resonance imaging (odds ratio [OR] 0.77, P.001) or injection (OR 0.94, P = .006). Asian patients had lower odds of receiving any hip X-ray (OR 0.72, P = .047) or knee injection (OR 0.83, P = .017). AA (total knee arthroplasty [TKA]: OR 0.51, P.001; total hip arthroplasty [THA]: OR 0.57, P.001), Hispanic (TKA: OR 0.69, P = .003; THA: OR 0.60, P = .006), and Asian (TKA: OR 0.73, P = .010; THA: OR 0.56, P = .010) patients had lower odds of undergoing TJA compared to Caucasians. We found that higher income quartiles had greater odds of receiving a magnetic resonance imaging and TJA, males had lower odds of receiving injections and greater odds of undergoing TJA, and Medicaid and self-pay patients had lower odds of undergoing TJA (P.05).After adjusting for sociodemographic factors, we found disparities in the imaging, administration of injections, and/or arthroplasty for AA, Asian, and Hispanic patients. Insurance status, income, and gender were also associated with imaging and treatments performed in managing hip and knee osteoarthritis.

This study aimed to better understand body mass index (BMI) change patterns and factors associated with BMI change before and after total hip arthroplasty (THA) in Class 2 and 3 obese patients, and assess if preoperative or postoperative BMI change affects postoperative clinical outcomes.We retrospectively reviewed World Health Organization Class 2 and 3 obese patients (BMI35.0 at surgery) who underwent THA at a tertiary medical center from 2010 to 2020. BMI was recorded at 1 year preoperatively (mean 11.6 months), and at most recent postoperative visit (mean 29.0 months). Baseline demographics and postoperative clinical outcomes were recorded.We reviewed 436 THAs with a mean age of 59.9 (11.5) years. Leading up to surgery 55.5% had unchanged BMI, and postoperatively 48.2% had unchanged BMI. Multivariate logistic regression revealed that those who lost BMI preoperatively were more likely to gain BMI postoperatively (odds ratio [OR] 3.28, confidence interval [CI] 1.83-5.97, P = .005), but those who gained5% BMI preoperatively had no association with BMI change postoperatively. Those in a higher BMI class preoperatively were less likely to gain BMI preoperatively (Class 3 obese patients: OR 0.001, CI 0.0002-0.004, P.001). African American patients were more likely to gain BMI preoperatively (OR 2.32, CI 1.16-4.66, P = .017). We did not detect an association between BMI change and postoperative clinical outcomes.In World Health Organization Class 2 or 3 obese patients, most maintained BMI between their first preoperative and final postoperative visit. Preoperatively, Class 3 obese patients were less likely to gain weight than Class 2 obese patients. The primary predictor of postoperative weight gain was preoperative weight loss. Weight change preoperatively and postoperatively were not associated with worse clinical outcomes.

Although patient factors have been associated with prosthetic joint infection (PJI) after primary total knee arthroplasty, there are insufficient data on the relationship of patient and technical factors with early PJI after aseptic revision.This is a retrospective study of 157 aseptic revisions performed by 2 surgeons at 1 academic center. A negative intraoperative culture during revision surgery was required for inclusion. Mean follow-up time was 3.8 years (standard deviation 2.8). PJI was defined by positive aspiration or draining wound, and an additional operation within 1 year of aseptic revision. Patient demographics, medical comorbidities, and technical factors were reviewed. Data points were evaluated with univariate and adjusted multivariate regression analyses.The prevalence of PJI after aseptic revision was 9% (14/157). The most common organism was Staphylococcus aureus. Initial treatment included debridement and liner exchange (11) and antibiotic spacer (3). Two patients ultimately had an above-knee amputation. Univariate analysis showed a significant difference in preoperative anemia (P.01), transfusion (P.01), and diabetes (P = .05) between cohorts. There was no association among the length of surgery, use of a metaphyseal cone, or the number of components revised and PJI. Adjusted logistic regression demonstrated that preoperative anemia (P.01) was a significant risk factor for PJI.The prevalence of early PJI was similar to other studies in the literature. Anemia was an independent predictor of PJI, while technical factors did not have an association. Medical optimization of patients should be considered prior to revision surgery.

OBJECTIVE To determine what factors increase the risk of early wound complications in patients undergoing direct anterior total hip arthroplasty whose wounds were closed with 2-octyl cyanoacrylate with mesh. METHODS This study was a retrospective review of 75 consecutive patients who underwent direct anterior total hip arthroplasty closed with 2-octyl cyanoacrylate with mesh. MAIN RESULTS Of 29 patients who were smokers, five patients (17.2%) developed a wound complication, whereas out of 46 nonsmokers, only one patient (2.2%) developed a wound complication (P = .029). CONCLUSIONS The authors recommend a closure technique that sufficiently protects the wound during healing, as well as preoperative patient optimization and smoking cessation.

Objectives Effective leadership and teamwork are imperative during pediatric cardiopulmonary resuscitations (CPR). The initial phase of pediatric CPR, termed the "first 5 minutes," has significant care delivery gaps in both leadership and team performance. The aim of the study was to describe the performance data of emergency department (ED) teams who performed CPR in a pediatric ED. Methods We conducted a retrospective video review of resuscitations involving pediatric patients younger than 21 years who presented in cardiac arrest to a tertiary pediatric ED. Descriptive statistics were used for data analysis. Results Twenty events met study inclusion criteria. Prearrival task completion included the following: estimated weight (90%), airway set-up (85%), epinephrine dose prepared (84%), defibrillator ready (75%), and intraosseous kit ready (50%). Median prearrival notification time was 5 minutes 34 seconds (interquartile range = 4:44-7:13) with no significant relationship between prearrival time and task completion. Within the first 5 minutes, the team leader provided a care summary in 84%, prioritized tasks in 95%, and assigned roles for airway management (90%), intravenous/intravenous access (63%), and CPR/pulse check (63%). Most critical tasks were completed within 1 minute; however, only 25% had defibrillator pads placed within the 5-minute window. Conclusions Our study of leadership and teamwork during the first 5 minutes of pediatric CPR care noted wide variation in team performance. Opportunities for improvements in CPR readiness can be incorporated into education and quality programs to drive improvements in the care of future pediatric patients experiencing cardiac arrest.

Minimizing pauses in chest compressions during cardiopulmonary resuscitation (CPR) is recommended by the American Heart Association (AHA) and is associated with improved patient outcomes. We studied the quality of pediatric CPR performed in a tertiary pediatric emergency department (ED) with a focus on pauses in chest compressions.We conducted an observational study of CPR quality in two pediatric EDs using video review during pediatric cardiac arrest. Events were reviewed for AHA guideline adherence. Parameters of CPR performance were described according to individual compressor segment. Pauses in compressions were analyzed for duration and pause activities.From a 30-month period, 81 cardiac arrests were analyzed, including 1003 individual compressor segments and 900 pauses. Median chest compression fraction was 91%, with a median pause duration of 4 s (IQR 2, 10); 22% of pauses were prolonged (10 s). Pulse checks occurred in 23% of pauses; 62% were prolonged. Checking a single pulse site (p 0.001) and having fingers ready pre-pause (p = 0. 001) were associated with significantly shorter pause duration. Pause duration was correlated with the number of pause tasks (r = 0.559, p 0.001). "Coordinated pauses" (pulse check, rhythm check and compressor change) were rare (6%) and long in duration (19 s; IQR 11, 30).Prolonged pauses in chest compressions occurred frequently during CPR and were associated with pulse checks and multiple simultaneous tasks. Checking a single pulse site with fingers ready on the pulse site pre-pause could decrease pause duration and improve CPR quality.

BackgroundIntubation is an essential, life-saving skill but associated with a high risk for adverse outcomes. Intubation protocols have been implemented to increase success and reduce complications, but the impact of protocol conformance is not known. Our study aimed to determine association between conformance with an intubation process model and outcomes.MethodsAn interdisciplinary expert panel developed a process model of tasks and sequencing deemed necessary for successful intubation. The model was then retrospectively used to review videos of intubations from 1 February, 2014, to 31 January, 2016, in a paediatric emergency department at a time when no process model or protocol was in existence.ResultsWe evaluated 113 patients, 77 (68%) were successfully intubated on first attempt. Model conformance was associated with a higher likelihood of first attempt success when using direct laryngoscopy (OR 1.09, 95% CI 1.01 to 1.18). The use of video laryngoscopy was associated with an overall higher likelihood of success on first attempt (OR 2.54, 95% CI 1.10 to 5.88). Thirty-seven patients (33%) experienced adverse events. Model conformance was the only factor associated with a lower odds of adverse events (OR 0.94, 95% CI 0.88 to 0.99).ConclusionsConformance with a task-based expert-derived process model for emergency intubation was associated with a higher rate of success on first intubation attempt when using direct laryngoscopy and a lower odds of associated adverse events. Further evaluation of the impact of human factors, such as teamwork and decision-making, on intubation process conformance and success and outcomes is needed.

Background Orthopaedic oncology patients are particularly susceptible to increased readmission rates and poor surgical outcomes, yet little is known about readmission rates. The goal of this study was to identify factors independently associated with 90-day readmission for patients undergoing oncologic resection and subsequent prosthetic reconstruction for metastatic disease of the hip and knee. Methods This was a retrospective comparative cohort study of all patients treated from 2013-2019 at a single tertiary care referral institution who underwent endoprosthetic reconstruction by an Orthopaedic Oncologist for metastatic disease of the extremities. The primary outcome measure was unplanned 90-day readmission. Results We identified 112 patients undergoing 127 endoprosthetic reconstruction surgeries. Metastatic disease was most commonly from renal (26.8%), lung (23.6%), breast (13.4%). The most common type of skeletal reconstruction performed was simple arthroplasty (54%). There were 43 readmissions overall (33.9%). When controlling for confounding factors, BMI >40, insurance status, peripheral vascular disease and longer hospital length of stay were independently associated with risk of readmission (p Conclusions Readmission rates for endoprosthetic reconstructions for metastatic disease are high. While predicting readmission remains challenging, risk stratification presents a viable option for helping minimize unplanned readmissions.

Objective Investigating patients’ perceptions regarding need for antibiotic prophylaxis during dental procedures after undergoing joint arthroplasty. Methods Questionnaire was administered to patients presenting at: 1)an orthopaedic office; 2)a dental office; regarding perceptions of antibiotic prophylaxis. Results 36 orthopaedic patients responded “Yes” to always taking prophylaxis; 36 patients responded “No” (36/72, 50.0% compliance). Five dental patients responded “Yes” to always taking prophylaxis; 19 patients responded “No” (5/24, 20.8% compliance) (p = 0.017). 67/135 orthopaedic patients (49.6%) endorsed some form of dental prophylaxis, versus 34/58 dental patients (58.6%) (p = 0.27). Conclusion Patient perceptions of the need for dental prophylaxis vary within orthopaedic and dental practices.

OBJECTIVE: To investigate patient factors influencing length-of-stay (LOS) after revision metal-on-metal (MoM) total hip arthroplasty (THA). METHODS: We reviewed 23 hips undergoing revision of a MoM THA with minimum 2-year follow-up. A multiple linear regression was calculated to predict LOS using multiple variables. RESULTS: Average length of stay (LOS) was 2.1 days. Multiple linear regression analysis identified a significant correlation between presence of an abductor injury (beta = 0.8886; p

The National Association of Emergency Medical Services (EMS) Physicians emphasizes the importance of high quality communication between EMS providers and emergency department (ED) staff for providing safe, effective care. The Joint Commission has identified ineffective handoff communication as a contributing factor in 80% of serious medical errors. The quality of handoff communication from EMS to ED teams for critically ill pediatric patients needs further exploration.This study assessed the quality of handoff communication between EMS and ED staff during pediatric medical resuscitations.We conducted a retrospective review of video recordings of pediatric patients who required critical care ("resuscitation") in the ED between January 2014 and February 2016 at a Level 1 pediatric trauma center. Handoff quality between EMS and emergency department teams was assessed for completeness, timeliness, and efficiency. Institutional review board approval was obtained.Sixty-eight resuscitations were reviewed; 28% presented in cardiac arrest, requiring cardiopulmonary resuscitation (CPR). Completeness of information communicated was variable and included chief complaint (88%), prehospital interventions (81%), physical exam findings (63%), medical history (59%), age (56%), and weight (20%). Completeness of specific vital sign reporting included: respiratory rate (53%), heart rate (43%), oxygen saturation (39%), and blood pressure (31%). Timeliness of communication included median patient handoff and report times of 50 seconds [IQR 30,74] and 108 seconds [IQR 62,252], respectively. Inefficient communication occurred in 87% of handoffs, including interruptions by ED staff (51%), questions from the ED physician team leader asking for information already communicated (40%), and questions by ED physician team leader requesting information not yet communicated (65%). When comparing non-CPR to CPR cases, only timeliness of patient handoff was significantly different for those patients receiving prehospital CPR.Handoff communication between EMS and ED teams during pediatric resuscitation was frequently incomplete and inefficient. Future educational and quality improvement interventions could aim to improve the quality of handoff communication for this patient population.

Objectives High-quality clinical research of resuscitations in a pediatric emergency department is challenging because of the limitations of traditional methods of data collection (chart review, self-report) and the low frequency of cases in a single center. To facilitate valid and reliable research for resuscitations in the pediatric emergency department, investigators from 3 pediatric centers, each with experience completing successful single-center, video-based studies, formed the Videography In Pediatric Emergency Research (VIPER) collaborative. Methods Our initial effort was the development of a multicenter, video-based registry and simulation-based testing of the feasibility and reliability of the VIPER registry. Feasibility of data collection was assessed by the frequency of an indeterminate response for all data elements in the registry. Reliability was assessed by the calculation of Cohen κ for dichotomous data elements and intraclass correlation coefficients for continuous data elements. Results Video-based data collection was completed for 8 simulated pediatric resuscitations, with at least 2 reviewers per case. Data were labeled as indeterminate by at least 1 reviewer for 18 (3%) of 524 relevant data fields. The Cohen κ for all dichotomous data fields together was 0.81 (95% confidence interval, 0.61-1.0). For all continuous (time-based) variables combined, the intraclass correlation coefficient was 0.88 (95% confidence interval, 0.70-0.96). Conclusions Initial simulation-based testing suggests video-based data collection using the VIPER registry is feasible and reliable. Our next step is to assess feasibility and reliability for actual pediatric resuscitations and to complete several prospective, hypothesis-based studies of specific aspects of resuscitative care, including of cardiopulmonary resuscitation, tracheal intubation, and teamwork and communication.

Study objective Guideline committees recommend postresuscitation debriefings to improve performance. "Hot" postresuscitation debriefings occur immediately after the event and rely on team recall. We assessed the ability of resuscitation teams to recall their performance in team-based, hot debriefings in a pediatric emergency department (ED), using video review as the criterion standard. We hypothesized that debriefing accuracy will improve during the course of the study. Methods Resuscitation physician and nurse leaders cofacilitated debriefings after ED resuscitations involving cardiopulmonary resuscitation (CPR) or intubation. Debriefing teams recorded their self-assessments of clinical performance measures with standardized debriefing forms. The debriefing form data were compared with actual performance measured by video review at 2 pediatric EDs over 22 months. CPR performance measures included time to automated external defibrillator pad placement, epinephrine administration timing, and compression pause timing. Intubation measures included occurrences of oxygen desaturation, number of intubation attempts, and use of end-tidal carbon dioxide monitoring. Results We analyzed 100 resuscitations (14 cardiac arrests, 22 cardiac arrests with intubation, and 64 intubations). The accuracy of debriefing answers was 87%, increasing from 83% to 91% between the first and second halves of the study period (7.7% difference; 95% confidence interval 0.2% to 15%). Debriefings that acknowledged an error in certain performance measures (ie, automated external defibrillator pad placement delay, multiple intubation attempts, and occurrence of oxygen desaturation) had significantly worse performance in those specific measures on video review. Conclusion Teams in postresuscitation debriefings had a higher degree of debriefing answer accuracy in the final 50 debriefings than in the first 50. Teams also distinguished various degrees of resuscitation performance.
