- Abstract
Introduction: Known as the "pinnacle of patient-centered care," shared decision-making (SDM) is the process that enables and encourages the health care provider, the patient, and/or their caregiver (parent or guardian) to participate collaboratively in medical decisions. Prior research indicates that children with emotional, developmental, or behavioral health conditions (EDB) are less likely to attain SDM than children with other special health care needs (SHCNs). This study investigates whether the presence of a medical home reduces disparities in SDM among children with EDB when compared to children with other SHCNs and the general pediatric population., Methods: Using the 2016 National Survey of Children's Health, we conducted weighted descriptive statistics to investigate the prevalence of medical home and SDM for children with (1) EDB, (2) other SHCNs, and (3) no SHCNs. We then employed a nested multivariate logistic regression model to examine whether the presence of a medical home reduced the disparity between children with EDB and their counterparts., Results: Nationally, 21% of children with EDB (n = 647,274), 14.0% of children with other SHCNs (n = 1,086,068), and 13% of children with no SHCNs (n = 883,969) did not attain caregiver-reported SDM in medical care. In each of the health condition groups, the presence of a medical home significantly improved the odds of SDM (p < 0.001). Presence of a medical home also reduced the disparities observed in caregiver-reported SDM among children with EDB as compared to those with other SHCNs and no SHCNs., Discussion: Ongoing investment in medical homes may reduce disparities in SDM experienced by children with EDB., (© 2021.

- Abstract
Hospitals have invested heavily in health information technology (HIT) which has been promoted as an integral component of quality, safe, and efficient health-care delivery. Research on the expanding use of such technology, however, has shown that user/technology interactions are shaped through practices of use that can yield far from normative, even unexpected outcomes. Drawing upon focus group and interview data from an inpatient, two-hospital health system in the United States, this paper considers the perceived impact of HIT implementation on work practices and roles for nurse managers and unit clerks. We find that HIT implementation generated significant reconfigurations of work practices at the expense of nurse/patient interaction. Following such changes, nursing leadership described re-prioritizing patient care and interaction - perceived to them as essential to the patient experience and unit functioning - through realignments in staffing that prioritized more versatile staff and task delegation of largely invisible, articulation work to unit clerks. Despite maintaining an integral role as "gatekeeper" and the "face on the floor," unit clerks experienced significant reconfigurations of their work and some concomitant uncertainty about their role. We consider the implications of our findings for literature on the socio-materiality of HIT, with particular attention to literature on work practices, roles, and the visibility of work within organizational power hierarchies., (Copyright © 2019 Elsevier Ltd.

- Abstract
Objective: The aim of this study is to describe the impact of the introduction of health information technology (HIT) on the utilization and payroll costs of nurse extenders and unit clerks in medicine and surgery units in a large regional health system., Background: Long-term policy goals of HIT implementation are reported to include system-level reductions in labor costs, achieved through improved efficiency., Methods: Using a retrospective cohort model, we analyzed how hours worked per patient day and staffing costs per patient day varied with the implementation of HIT over time at 2 different hospitals within a health system., Results: Implementation of electronic medication administration records was not associated with significant changes in staffing or labor costs. Both labor hours and costs associated with nurse extenders and unit clerks were significantly reduced after the subsequent addition of computerized provider order entry. Simultaneously, units that did not implement any HIT experienced a significant increase in both labor hours and costs., Conclusion: Health information technology implementation in the inpatient setting is associated with significant savings in labor hours and costs in non-registered nursing roles.

- Abstract
Attention Deficit Hyperactivity Disorder (ADHD) has been medicalized in the United States since the 1960s. Primarily used in North America until the 1990s, ADHD diagnosis and treatment have increasingly been applied internationally. After documenting the expansion of ADHD in a global context, this paper presents five brief international examples examining ADHD usage and expansion: the United Kingdom, Germany, France, Italy and Brazil. We then identify and describe several vehicles that facilitate the migration of the ADHD diagnosis: the transnational pharmaceutical industry; the influence of western psychiatry; moving from ICD to DSM diagnostic criteria; the role of the Internet including the related advent of easily accessible online screening checklists; and advocacy groups. Finally, we discuss what this globalization of a diagnosis reflects about the potential global medicalization of other conditions., (Copyright © 2014 Elsevier Ltd. All rights reserved.)

- Abstract
Introduction: Tube thoracostomy is a common procedure used to treat traumatic chest injuries. Although the mechanism of injury traditionally does not alter chest tube management, complication rates may vary depending on the severity of injury. The purpose of this study was to investigate the incidence of and risk factors associated with chest tube complications (CTCs) following thoracic trauma., Methods: A retrospective chart review of all trauma patients (≥16 years old) admitted to an urban level 1 trauma centre (1/2007-12/2007) was conducted. Patients who required chest tube (CT) therapy for thoracic injuries within 24 h of admission and survived until CT removal were included. CTCs were defined as a recurrent pneumothorax or residual haemothorax requiring CT reinsertion within 24 h after initial tube removal or addition of new CT >24 h after initial placement. Variables including demographic data, mechanism, associated injuries, initial vital signs, chest abbreviated injury score (AIS), injury severity score (ISS), Glasgow coma score (GCS) and length of stay (LOS) and CT-specific variables (e.g. indication, timing of insertion, and duration of therapy) were compared using the chi square test, Mann-Whitney test, and multivariate analysis., Results: 154 patients were included with 22.1% (n=34) developing a CTC. On univariate analysis, CTCs were associated with longer ICU and hospital LOS (p=0.02 and p<0.001), increased chest AIS (p=0.01), and the presence of an extrathoracic injury (p=0.047). Results of the multivariate analysis indicated that only increased chest AIS (OR 2.49; p=0.03) was a significantly independent predictor of CTCs., Conclusions: CTCs following chest trauma are common and are associated with increased morbidity. The severity of the thoracic injury, as measured by chest AIS, should be incorporated into the development of CT management guidelines in order to decrease the incidence of CTCs., (Copyright © 2011 Elsevier Ltd.

- Abstract
Objectives: The effects of perceptions and behaviors related to culturally patterned socioeconomic obligations on catecholamine excretion rates were studied in a cross-sectional sample of Samoan adults., Methods: A total of 378 participants, ages 29-62 years, from 9 villages throughout Samoa, provided timed overnight urine specimens, and self-reported perceptions and behaviors associated with contributions to one's family, aiga, and chief, matai, and communal gift exchanges, fa'alavelave. Urinary norepinephrine and epinephrine excretion rates were measured by high performance liquid chromatography with electrochemical detection. Age (≤40 vs. >40 years) and gender-specific regression models were estimated to detect associations with catecholamine excretion., Results: Young women who contribute more to their matai, who consider fa'alavelave to be a financial strain, and who view their contribution to their matai to be "just right," had significantly higher residence-adjusted norepinephrine excretion. Young women who contribute more to their matai, who consider fa'alavelave to be a financial strain, and who consider their contribution to their aiga not to be a burden, had higher epinephrine excretion. Older men who contribute more to their aiga and who perceive their contribution to their aiga to be "just right" had increased residence-adjusted epinephrine excretion., Conclusions: Individual-level perceptions and behaviors related to traditional socioeconomic obligations are a significant correlate of increased overnight catecholamine excretion rates. Higher excretion rates may be attributed to psychosocial stress arousal associated with a discordance between personal desires for upward social mobility, and family and community-based socioeconomic obligations. Changes in patterns of individual-level psychosocial stress arousal may contribute to cardiovascular disease risk in modernizing Samoans., (Copyright © 2011 Wiley-Liss, Inc.)

- Abstract
This study compared the use of barbed suture to a traditional skin closure method for incision closure in free flap breast reconstruction. A retrospective study compared the two closure methods in consecutive series of patients undergoing autologous breast reconstruction between January 2007 and January 2009. Outcomes included total duration of operation and wound complications. We also performed a cost analysis. Use of the barbed suture significantly decreased operative time for unilateral cases by an average of 45 minutes (405 versus 360 minutes, P = 0.02). For bilateral cases, the mean operative time was decreased by an average of 10 minutes (510 versus 500 minutes, P = 0.44). There were more episodes of delayed wound healing in the bilateral barbed suture group (33/46 [72%] versus 15/31 [48%], P = 0.04). No statistical difference was noted between the two groups with regard to dehiscence, infection, or suture extrusion. Use of the barbed suture was, however, more cost-effective. The use of a barbed suture in the closure of abdominal and breast incisions in free flap breast reconstruction may expedite wound closure and reduce the cost of the procedure but may increase wound complications., (© Thieme Medical Publishers.)

- Abstract
Background: Intimate partner violence (IPV) is an underappreciated cause of morbidity and mortality in female trauma patients. We investigated the impact of a domestic violence education program for trauma residents on the detection of IPV., Study Design: In January 2008, an educational IPV program was implemented for all trauma residents. A retrospective review of all female patients evaluated by the trauma service before and after institution of the IPV program was performed. Medical records were reviewed for demographic data, injury mechanism, social habits, and IPV documentation. Chi-square and Fisher's exact tests were used to compare patients before and after institution of the educational IPV program., Results: The records of 645 female trauma patients evaluated in 2007 and 2008 were reviewed. Patients were not routinely asked about IPV, despite implementation of the educational program; 39.9% were asked about IPV in 2007 versus 46.1% in 2008 (p = 0.11). The positive disclosure of IPV did not increase from 2007 to 2008 (20.1% versus 21.2%; p = 0.83). Documentation about social habits increased considerably. In 2008, patients were asked more regularly about alcohol (71.8% versus 80.8%; p = 0.01), drugs (64.1% versus 73.7%; p = 0.01), and tobacco use (67.0% versus 78.1%; p = 0.002). Importantly, patients with documented IPV (n = 57) frequently presented to the trauma team with nonviolent mechanisms of injury (n = 30, 52.6%)., Conclusions: IPV is a frequent finding in female trauma patients. Despite increased education, questions about IPV are not documented routinely. In addition, screening at-risk patients by mechanism will underestimate the prevalence of IPV. Universal screening should be mandated to increase IPV detection and enhance opportunities for intervention., (Copyright © 2011 American College of Surgeons. Published by Elsevier Inc.

- Abstract
Background: Bilateral mastectomy in women diagnosed with unilateral breast cancer is on the rise in the USA. One contributing factor is increased awareness of contralateral breast cancer risk. Positive testing for deleterious mutation in BRCA1/2 is a concrete measure of this contributing factor. We hypothesize that breast cancer surgery trend change is temporally associated with the introduction of BRCA1/2 genetic testing around 1996., Methods: Our study cohort included 158 BRCA1 or BRCA2 mutation carriers diagnosed with unilateral breast cancer between 1963 and 2009. Mutation carriers with ovarian cancer or bilateral breast cancer were excluded. Breast surgery and breast reconstruction surgery trends were analyzed according to year of breast cancer diagnosis or when bilateral mastectomy was performed, respectively., Results: Surgery trends changed significantly over time. We observed a significant drop in the rate of unilateral mastectomy (P < 0.001) after the period 1996-2000, and the rate of bilateral mastectomy appears to be on the rise, up to 30.3% between 2006 and 2009. Breast reconstruction trends also changed significantly over time, with a significant rise in the rate of free flap reconstruction to 58.8% between 2006 and 2009., Conclusions: Our results demonstrated a significant decrease in unilateral mastectomy with a rise in bilateral mastectomy after the period 1996-2000, a period which encompassed the year when genetic testing of the two BRCA1/2 genes became commercially available, hence supporting our hypothesis.

- Abstract
Background: Ecological and sociodemographic correlates of stress may contribute to cardiovascular disease risk in modernizing Samoans., Aim: The effects of peri-urban vs rural residence, education, occupation, caffeine intake and cigarette consumption on urinary catecholamine excretion were studied in Samoan adults., Subjects and Methods: Five hundred and seven participants, aged 29-69 years, were randomly selected from nine villages throughout Samoa. Sociodemographic and lifestyle factors were assessed by questionnaire. Epinephrine and norepinephrine excretion rates were measured by high performance liquid chromatography with electrochemical detection in overnight urine samples. Age ( ≤ 40 vs >40 years) and gender-specific regression models were estimated to detect associations with BMI-adjusted catecholamine excretion., Results: Norepinephrine was significantly higher in peri-urban young men and older women. Epinephrine was significantly higher in peri-urban older men. Adjustment for caffeine attenuated the relationship between residence and norepinephrine in young women., Conclusion: General residential exposure to modernization in urban villages is a significant correlate of increased overnight catecholamine excretion rates and is consistent with past studies. Caffeine consumption in younger women plays a complex role in stress-related catecholamine excretion. Further studies of individual level attitudinal and behavioural factors in Samoans are needed to understand psychosocial stress, physiologic arousal and health.

- Abstract
Background and Purpose: Postoperative incontinence is multifactorial after radical prostatectomy. Using endorectal coil MRI, we examined features of the male urethra and accompanying muscular sphincter to predict continence after robot-assisted radical prostatectomy (RARP)., Patients and Methods: 80 patients underwent preoperative 1.5 Tesla endorectal coil MRI. Urethral length was measured in the coronal plane. All patients underwent RARP. Questionnaires were completed by patients at monthly intervals. The primary end point was time to continence defined as necessitating 0 to 1 pad per day (PPD). Statistical analysis was performed using Cox regression models to create both univariate and multivariate survival models., Results: Mean age was 59.7 (standard deviation [SD] 7.1); 98% had bilateral nerve sparing. Mean urethral length was 17.1 mm (SD 4.5 mm). Mean prostate size was 34.7 g (SD 17.8). By 3 months, 60 patients achieved 1 PPD (mean 8.1 weeks, SD 9.4) and 34 patients achieved 0 PPD (mean 10.5 weeks, SD 8.0). Time to social continence was significantly related to prostate size both as a continuous variable (P=0.01), and as a dichotomized variable of ≥ 50 vs<50 g (P=0.02). Increased urethral length was related to decreased time to continence both as a continuous variable (P=0.06), and when dichotomized to ≥ 20 vs<20 mm (P=0.08). In addition to larger prostate size (hazard ratio [HR] 0.97, P<0.04), older age (0.95 P<0.025) was also associated with a longer time to achieve 0 PPD. Multivariate analysis revealed that longer urethral length was associated with a faster recovery of continence (HR 1.11, P<0.01). After controlling for age and urethral length, patients with a prostate size ≥ 50 g had 75% lower likelihood of achieving continence at all time points when compared with patients with prostate size <50 g (HR 0.25; 95% confidence interval: 0.06, 1.06; P=0.06)., Conclusions: Longer urethral length increased the likelihood of achieving continence at all time points postoperatively. Advanced age and larger prostate size were negatively associated with continence outcomes.

- Abstract
Purpose: 2-Deoxy-2-[F-18]fluoro-D-glucose (FDG) uptake may be a useful surrogate marker for proliferation index, but the correlation has not always been clear-cut. Previous research by our group suggests that FDG-positron emission tomography (PET) is sensitive in detecting triple negative breast cancer. We therefore performed a pilot study to test if FDG uptake correlated with proliferation index in women with triple negative cancer., Procedures: To determine whether proliferation index correlates with metabolic uptake of FDG in women with triple negative breast cancer, we performed a retrospective analysis correlating %Ki67 nuclear stain with tumor maximum standardized uptake values (SUVmax) in a group of 41 women, 22 with triple negative and 19 with non-triple negative breast cancer., Results: As expected, [18F]-PET imaging was significantly more sensitive in detecting triple negative breast cancer than non-triple negative breast cancer, 95.5% vs 68.4% (p = 0.036). In general, SUVmax and %Ki67 nuclear stain values rise as histologic grade worsens. Histologic grade of triple negative breast cancer was more often poorly differentiated than non-triple negative cancer (p = 0.001). SUVmax correlated with %Ki67 nuclear staining in our entire cohort (spearman correlation = 0.485, p = 0.002). Moreover, this significant correlation appeared to be driven primarily by a subset of women with triple negative cancer (spearman correlation = 0.497, p = 0.019)., Conclusions: Degree of tumor FDG uptake correlated significantly with proliferation index in women with triple negative breast cancer suggesting a potential role of FDG-PET in treatment response monitoring for this group of women. Future studies are necessary to define the role of PET imaging as a non-invasive means to monitor breast cancer treatment response in the neoadjuvant setting.

- Abstract
Introduction: Radical cystectomy (RC) remains the gold standard treatment for patients with muscle-invasive bladder cancer. Unfortunately, a significant proportion of patients will have lymph node involvement at the time of RC. We set out to determine the impact of adjuvant cisplatin-based chemotherapy (AC) in a cohort of lymph node positive patients following RC., Patients and Methods: We reviewed our RC database and isolated patients with lymph node positive disease at the time of RC. Univariate and multivariable analysis was performed to identify predictors of poor outcome in patients receiving AC. Overall survival (OS), disease specific survival (DSS) and recurrence free survival (RFS) were calculated for those patients who received AC compared to those who did not., Results: Of the 316 patients, we identified 85 patients with metastatic lymph node involvement at the time of RC. Fifty-five (65%) of these patients received AC. Median follow up was 46 months. On multivariable analysis lymph node positive patients receiving AC had significantly improved OS, DSS and RFS compared to patients who did not receive AC (p = 0.031, p = 0.028, p = 0.004). The delivery of AC conferred the greatest recurrence-free, disease-specific, and overall survival advantages to those with lymph node densities (LND) of < 20% with (p = 0.016, p = 0.011, p = 0.007, respectively)., Conclusion: AC administered to patients with known lymph node metastasis conferred a significant survival advantage compared to observation. Furthermore, a LND of < 20% predicts of a more favorable response to AC. Further studies in larger patient populations are warranted to reveal the exact impact of AC in this subset of patients.

- Abstract
Objective: To evaluate the utility of estimated tumour volume, number of positive surgical margins (PSMs), and margin location for predicting biochemical failure in patients with PSM, in an attempt to better risk-stratify the heterogeneous group of patients at high risk of biochemical failure after radical prostatectomy (RP) for prostate cancer., Patients and Methods: We reviewed our database of 2410 patients who had RP, and isolated 423 with PSMs who had a prostate-specific antigen (PSA) nadir at undetectable levels. Kaplan-Meier curves were used for univariate survival analysis, with the log-rank test used to examine differences between survival curves. Multivariate Cox regression analysis was used to assess the independent main effect of estimated tumour volume, number of PSMs and margin location on biochemical-free survival., Results: Increasing estimated tumour volume was directly associated with increasing risk of biochemical failure in patients with PSMs (P = 0.041). Patients with more than one PSM were at greater risk of biochemical failure than those with one PSM (P = 0.001). Margin location had no effect on biochemical-free survival in patients with PSMs. When incorporated into a multivariate Cox regression model including age, preoperative PSA level and pathological Gleason score, estimated tumour volume and number of PSMs remained independent predictors of biochemical recurrence., Conclusions: Coupled with other variables before and after RP, both estimated tumour volume and number of PSMs might serve to further discriminate those patients most likely to benefit from immediate adjuvant radiotherapy after RP.

- Abstract
Background: The goal of this study was to determine the self-reported breast cancer screening practices of American plastic surgeons and the degree to which those practices adhere to the American Cancer Society guidelines. An independent analysis of subgroups divided by gender, years in practice, and practice setting was performed and the implications of the results are discussed., Methods: The authors conducted an online survey of the members of the American Society of Plastic Surgeons. Questions assessed practice composition, American Cancer Society guideline familiarity, and preoperative breast cancer screening in patients seeking aesthetic breast surgery. Responses were summarized, subgroup comparisons were made, and logistic regression was used to determine predictors of physician practices., Results: The 1066 respondents were predominantly male (82 percent) and consisted largely of private practitioners (73 percent). In total, 47 percent appeared to follow the American Cancer Society guidelines, while 64 percent claimed familiarity. Being male predicted more accurate guideline knowledge, but being female resulted in more aggressive screening and possibly more diagnoses. Number of years in practice and familiarity with the American Cancer Society guidelines also resulted in more perioperative diagnoses., Conclusions: Knowledge of the American Cancer Society guidelines is an essential component of effective cancer screening, but only two-thirds of plastic surgeons claim familiarity with them, and fewer than half report concordant practices. As plastic surgeons who often perform surgical procedures on the breast in women with no history of breast disease, we have an obligation to understand and apply consistent, reliable breast cancer screening practices to ensure the well-being of our patients.

- Abstract
Objectives: To evaluate the effect of positive surgical margins in patients with muscle-invasive transitional cell carcinoma of the bladder on survival., Methods: A retrospective evaluation of a prospectively maintained radical cystectomy database consisting of the data from 344 patients was performed. Cox regression analysis was done, and Kaplan-Meier tables were developed to evaluate the contribution of this finding to clinical outcomes., Results: A total of 304 (88.4%) patients had negative surgical margins in the radical cystectomy specimen, and 40 (11.6%) had positive surgical margins. On univariate analysis, positive surgical margins conferred a significant risk of poorer clinical outcomes. The 5-year overall (OS) and disease-specific survival (DSS) rate was 9% and 18% for patients with positive margins compared with 48% and 65% for patients with negative margins, respectively. The multivariate analysis demonstrated a significant independent risk of decreased recurrence-free survival, DSS, and OS for patients with positive surgical margins. The corresponding hazard ratios were 2.29 (95% confidence interval 1.54-3.41, P < .001), 1.71 (95% confidence interval 1.15-2.56, P < .009), and 1.70 (95% confidence interval 1.23-2.34, P < .001). Despite these findings, patients with positive margins and node-negative disease experienced improved DSS and recurrence-free survival (P = .001 P and = .009, respectively) if >15 lymph nodes were removed during surgery., Conclusions: The presence of positive surgical margins in the pathologic specimen confers a significant independent risk of reduced recurrence-free survival, DSS, and overall survival. Nevertheless, patients with positive surgical margins will still benefit from a meticulous pelvic lymph node dissection.

- Abstract
Background: Recent studies have shown that breast cancer detected by screening has a more favorable prognosis than interval breast cancer. To further understand the biologic significance of this finding, we investigated the association of disease recurrence, local and distant, with the method of detection of the primary breast cancer in a cohort of 1686 women treated with breast conservation., Patients and Methods: The charts of 1686 women with primarily stage I or II invasive breast cancer treated by breast conservation between 1977 and 2002 were reviewed. The median length of follow-up was 6 years. Univariate and multivariate analyses using binary logistic regression were performed for 2 subgroups: (1) those with local recurrence versus those without; and (2) those with distant metastasis versus those without distant metastasis., Results: Our data confirmed several of the well-known risk factors for local and distant recurrence. In addition, we found that individuals with breast cancer detected on physical examination alone have a significantly higher risk for local recurrence compared with patients with cancer detected on mammogram alone, independent of tumor size (odds ratio [OR], 2.369; 95% CI, 1.235-4.547; P = .01). We also found a similar correlation for risk of distant metastasis in these 2 groups of women (OR, 2.201; 95% CI, 1.211-3.998; P = .01)., Conclusion: Breast cancers that are palpable might represent an aggressive biologic subtype with an increased risk of local and distant recurrence. Risk stratification might need to include this clinical feature in addition to conventional prognostic factors.
