Patient Perception of Medical Student Professionalism: Does Attire Matter?

INTRODUCTION: Patient compliance and outcomes have been shown to be influenced by the quality of the doctor-patient relationship. In addition, the effect of physician attire on the patient's perception of the physician has been long appreciated. Data shows that professional attire is preferred by patients. Whereas treating physicians are the backbone of patient management, medical students are often a patient's first encounter in a teaching clinic. Patient perception of the student may impact their rating of the attending physician. Despite this, medical students are often dressed wearing scrubs in surgery clinic. The purpose of this study was to determine if patient perception of medical students would be affected by the students' attire. METHODS: A 7-item, validated professionalism scale was used to survey surgery clinic patients whose initial examinations were performed by a medical student. Students were blinded and randomly assigned to wear professional attire versus scrubs. Patients' responses of 'strongly agree' were compared to lower ratings for each item. RESULTS: One hundred twenty-three patients completed our survey, 63 (51.2%) wearing scrubs and 60 (48.8%) in professional attire. The average age was 49.7 ± 15.8 years. In the professional attire group, there was no significant association for any of the 7 items. However, in the scrubs group, all 7 items were significant such that a higher proportion of patients under the age of 60 rated medical students wearing scrubs higher than did patients aged 60 and above. CONCLUSION: Students in scrubs were perceived to be less knowledgeable, competent, and professional by older patients. In contrast, younger patients seemed unaffected by the dress of medical students in clinic. Older patients may judge the medical community's growing acceptance of more casual attire in the workplace as less professional, potentially affecting patient satisfaction. Surgical educators should require a standard of professional attire for students in clinic.

The health literacy of hospitalized trauma patients: We should be screening for deficiencies.

BACKGROUND: Although the impact of health literacy (HL) on trauma patient outcomes remains unclear, recent studies have demonstrated that trauma patients with deficient HL have poor understanding of their injuries, are less likely to comply with follow-up, and are relatively less satisfied with physician communication. In this study, we sought to determine if HL deficiency was associated with comprehension of discharge instructions. METHODS: In this prospective study, hospitalized trauma patients underwent evaluation of HL prior to discharge. Newest Vital Sign (NVS) instrument was used to score HL as deficient, marginal, or proficient. Three days postdischarge, patients were telephonically administered a six-point scored questionnaire regarding comprehension of discharge instructions. A general linear model was used to determine the association between HL and comprehension of discharge instructions. RESULTS: Sixty-three patients were administered both NVS and discharge instruction questionnaire. Ten (15.9%) patients scored as deficient in HL on the NVS screen, 16 (25.4%) as marginally proficient, and 37 (58.7%) as proficient. The HL proficiency significantly predicted follow-up score with increasing proficiency associated with higher scores on the discharge comprehension assessment (p < 0.001). Adjusted mean scores (± SE) for deficient, marginal, and proficient patients were 2.8 ± 0.5, 3.2 ± 0.4, and 4.7 ± 0.2. Post hoc comparisons demonstrated significant differences between proficient with marginal proficiency (p = 0.002) and deficient proficiency (p = 0.001). CONCLUSION: Performance on bedside test of HL among trauma inpatients predicted ability to comprehend instructions following hospital discharge. This study supports the value of HL screening prior to discharge. The HL-deficient patients may benefit from a transitional care program to improve comprehension of discharge instructions after leaving the hospital.

Google Street View assessment of environmental safety features at the scene of pedestrian automobile injury.

BACKGROUND: Pedestrians struck by automobiles are at significant risk for mortality. Multiple environmental features have been developed to promote separation of pedestrians from motor vehicles. However, data on the effectiveness of these pedestrian traffic safety features are lacking. The purpose of this study was to use Google Street View to assess the locations of pedestrian-automobile injury and evaluate the relationship of environmental pedestrian safety features to pedestrian involved crashes. METHODS: Our trauma registry was queried for pedestrians injured by automobile collision. Google Street View was used to identify safety features present at each injury location. A composite safety score was created by summing the number of safety features at each crash location. A logistic regression model was performed to evaluate the impact of safety features on mortality. RESULTS: Our sample consisted of 631 patients (69.3% male) with an average age of 40.4 ± 17.0 years and median Injury Severity Score of 10 (5-22). A multivariate logistic regression revealed safety score (range, 0-6) significantly predicted mortality with each one-unit increment associated with a 27.8% decrease in risk of mortality. CONCLUSION: Increasing number of safety features as represented in a composite score may decrease risk of pedestrian mortality. Google Street View appears to be a viable tool to study the presence and effectiveness of these pedestrian safety features. LEVEL OF EVIDENCE: Epidemiological, level III.

Community Need Index (CNI): a simple tool to predict emergency department utilization after hospital discharge from the trauma service.

BACKGROUND: Emergency department (ED) visits after hospital discharge may reflect failure of transition of care to the outpatient setting. Reduction of postdischarge ED utilization represents an opportunity for quality improvement and cost reduction. The Community Need Index (CNI) is a Zip code-based score that accounts for a community's unmet needs with respect to healthcare and is publicly accessible via the internet. The purpose of this study was to determine if patient CNI score is associated with postdischarge ED utilization among hospitalized trauma patients. METHODS: Level 1 trauma patient admitted between January 2014 and June 2016 were stratified by 30-day postdischarge ED utilization (yes/no). CNI is a nationwide Zip code-based score (1.0-5.0) and was determined per patient from the CNI website. Higher scores indicate greater barriers to healthcare per aggregate socioeconomic factors. Patients with 30-day postdischarge ED visits were compared with those without, evaluating for differences in CNI score and clinical and demographic characteristics. RESULTS: 309 of 3245 patients (9.5%) used the ED. The ED utilization group was older (38.3±15.7 vs. 36.3±16.4 years, p=0.034), more injured (Injury Severity Score 10.4±8.7 vs. 7.7±8.0, p<0.001), and more likely to have had in-hospital complications (17.5% vs. 5.4%, p<0.001). Adjusted for patient age, injury severity, gender, race/ethnicity, penetrating versus blunt injury, alcohol above the legal limit, illicit drug use, the presence of one or more complications and comorbidities, hospital length of stay, and insurance category, CNI score ≥4 was associated with increased utilization (OR 2.0 [95% CI 1.4 to 2.9, p<0.001]). DISCUSSION: CNI is an easily accessible score that independently predicts postdischarge ED utilization in trauma patients. Patients with CNI score ≥4 are at significantly increased risk. Targeted intervention concerning discharge planning for these patients represents an opportunity to decrease postdischarge ED utilization. LEVEL OF EVIDENCE: III, Prognostic and Epidemiological.

Pneumomediastinum in blunt trauma: If aerodigestive injury is not seen on CT, invasive workup is not indicated.

BACKGROUND: Pneumomediastinum following blunt trauma is often observed on CT imaging, and concern for associated aerodigestive injury often prompts endoscopy and/or fluoroscopy. In recent years, adoption of multi-detector CT technology has resulted in high resolution images that may clearly identify aerodigestive injuries. The purpose of this study was to evaluate the utility of multi-detector CT in the identification of blunt aerodigestive injuries. METHODS: Over five years, patients with pneumomediastinum following blunt trauma were identified from the registry of a level 1 trauma center. All CT imaging of trauma patients during this time period was accomplished with 64-slice scanners. RESULTS: 127 patients with blunt traumatic pneumomediastinum were identified. Five airway injuries were identified, and all injuries were evident on CT imaging. No patient was found to have airway injury by endoscopy that was not evident on CT. No patient had an esophageal injury. CONCLUSION: Multi-detector CT imaging identifies aerodigestive injuries associated with pneumomediastinum following blunt trauma. The absence of a recognizable aerodigestive injury by CT effectively rules out the presence of such injury.

Letting the Numbers Speak for Themselves: A Simple Approach to Cost Reduction for Laparoscopic Appendectomy.

Instrument choices are influenced primarily by a surgeon's training and individual preference. Cost is often of secondary interest, particularly in the absence of any contracted fiscal obligation to the hospital. The purpose of this study was to evaluate how a simple intervention involving dissemination of cost data among a surgeon peer group influenced behavior with respect to surgical instrument choice. Cost data for laparoscopic appendectomies between July-December 2016 were disseminated to surgeons belonging to the same department of a teaching hospital. Each surgeon was provided his or her own cost data along with blinded data for his or her peers for comparison. Cost for each disposable instrument used among the group was provided for reference. Costs of laparoscopic appendectomy performed after the intervention (June-December 2017) were compared with costs before the intervention, for both individual surgeons and the group as a whole. A random effects linear regression model clustered on surgeon was then used to assess the average cost saving of the intervention while accounting for the intracorrelation of surgeon costs. One outlier was removed from the analysis, resulting in a cohort of 89 cases before the intervention and 74 postintervention. After outlier removal, data were normally distributed. The mean cost per case decreased for 10 of the 11 surgeons analyzed (minimum decrease of $7 to maximum decrease of $725). The remaining surgeon increased from an average of $985 ± 235 pre-intervention to $1003 ± 227 postintervention. The average cost saving for the group was $238 ± 226 and was associated with an average reduction in cost of 21 per cent. A linear regression analysis clustered on surgeon suggested the intervention was associated with an average saving of $260 (ß = -260, SE = 39, P < 0.001). After dissemination of cost data among surgeon peers, a reduction in costs was observed. Most notably, significant savings occurred in the absence of any mandate or incentive to reduce costs. Providing cost data to surgeons to facilitate natural competition among peers is a simple and effective tool for reducing operating room costs.

Crisis under the radar: Illicit amphetamine use is reaching epidemic proportions and contributing to resource overutilization at a Level I trauma center.

INTRODUCTION: Trauma centers reported illicit amphetamine use in approximately 10% of trauma admissions in the previous decade. From experience at a trauma center located in a southwestern metropolis, our perception is that illicit amphetamine use is on the rise and that these patients utilize in-hospital resources beyond what would be expected for their injuries. The purposes of this study were to document the incidence of illicit amphetamine use among our trauma patients and to evaluate its impact on resource utilization. METHODS: We conducted a retrospective cohort study using 7 consecutive years of data (starting July 2010) from our institution's trauma registry. Toxicology screenings were used to categorize patients into one of three groups: illicit amphetamine, other drugs, or drug-free. Adjusted linear and logistic regression models were used to predict hospital cost, length of stay, intensive care unit admission, and ventilation between drug groups. Models were conducted with combined injury severity (Injury Severity Score [ISS]) and then repeated for ISS of less than 9, ISS 9 to 15, and ISS 16 or greater. RESULTS: Eight thousand five hundred eighty-nine patients were categorized into the following three toxicology groups: 1,255 (14.6%) illicit amphetamine, 2,214 (25.8%) other drugs, and 5,120 (59.6%) drug-free. Illicit amphetamine use increased threefold over the course of the study (from 7.85% to 25.0% of annual trauma admissions). Adjusted linear models demonstrated that illicit amphetamine among patients with ISS of less than 9 was associated with 4.6% increase in hospital cost (p = 0.019) and 7.4% increase in length of stay (p = 0.043). Logistic models revealed significantly increased odds of ventilation across all ISS groups and increased odds of intensive care unit admission when all ISS groups were combined (p = 0.001) and within the group with ISS of less than 9 (p = 0.002). CONCLUSIONS: Hospital resource utilization of amphetamine patients with minor injuries is significant. Trauma centers with similar epidemic growth in proportion of amphetamine patients face a potentially significant resource strain relative to other centers. LEVEL OF EVIDENCE: Prognostic/Epidemiological, level II; Therapeutic, level III.

Early Clinical Outcomes of Transcatheter Aortic Valve Replacement in Left Ventricular Outflow Tract Calcification: New-Generation Device vs Early-Generation Device.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) in cases with left ventricular outflow tract calcification (LVOT-CA) remains a challenging procedure. The aim of this study was to compare the early outcomes of patients undergoing TAVR in LVOT-CA with new-generation devices vs early-generation devices. METHODS: Between January 2014 and December 2016, a total of 433 patients with severe aortic stenosis who had a preprocedural multidetector computed tomography underwent TAVR in a LVOT-CA. After propensity matching, data from 119 patients in each group were analyzed. TAVR endpoints and adverse events were defined according to the Valve Academic Research Consortium-2. RESULTS: Compared with early-generation devices (Edwards Sapien/Sapien XT/CoreValve), new-generation devices (Sapien 3/Evolut R) had significantly lower incidence of mild-moderate paravalvular leak (PVL) (1.7% new vs 7.6% early; P=.03), tended to have lower incidence of moderate or severe PVL (5.0% new vs 11.8% early; P=.06), had no significant difference in device success (89.1% new vs 83.2% early; P=.19), and had a significantly higher early safety rate at 30 days (93.3% new vs 84.9% early; P=.04). For cardiac conduction disturbances, new-generation and early-generation devices had similarly high rates of new permanent pacemaker implantation (16.8% new vs 15.1% early; P=.72), whereas the number of patients who developed new-onset left bundle-branch block (LBBB) were significantly higher in those with new-generation devices (16.0% new vs 6.7% early; P=.03). CONCLUSION: In the setting of LVOT-CA, patients with new-generation devices compared to those with early-generation devices had acceptable clinical outcomes except for cardiac conduction disturbances, especially in new-onset LBBB.

Management of Biliary Stricture Following Emergent Pancreaticoduodenectomy for Trauma: Report of Two Cases.

Stricturing of the biliary-enteric anastomosis is a known complication of emergent pancreaticoduodenectomy (PD) performed for trauma. Percutaneous techniques have become the first-line option for the management of these strictures. In cases where percutaneous intervention fails, surgical revision of the biliary enteric anastomosis is necessary. We present two cases of young males with penetrating injuries to the pancreatic head managed with PD and subsequently developed post-operative biliary strictures. The biliary stricture was managed successfully with percutaneous intervention for one of the patients. The other patient required surgical revision of the biliary anastomosis. Pancreaticoduodenectomy is typically performed in patients with malignant or benign biliary obstruction with associated ductal dilatation. In the setting of trauma, the bile duct is typically non-dilated, creating greater susceptibility for anastomotic stricture. Although such strictures may be amenable to percutaneous cholangioplasty, strictures involving distal anastomoses may require operative revision. Thus, we suggest creating the more proximal hepaticojejunostomy during the initial operation, as this may benefit the success of percutaneous management should a stricture develop. Operative revision is the definitive management of post-PD biliary stricture.

Health literacy and quality of physician-trauma patient communication: Opportunity for improvement.

BACKGROUND: Although physician-patient communication and health literacy (HL) have been studied in diverse patient groups, there has been little focus on trauma patients. A quality improvement project was undertaken at our Level I trauma center to improve patient perception of physician-patient communication, with consideration of the effect of HL. We report the first phase of this project, namely the reference level of satisfaction with physician-patient communication as measured by levels of interpersonal care among patients at an urban Level I trauma center. METHODS: Level I trauma center patients were interviewed during hospitalization (August 2016 to January 2017). Short Assessment of Health Literacy tool was used to stratify subjects by deficient versus adequate HL. Interpersonal Processes of Care survey was administered to assess perception of physician-patient communication. This survey allowed patients to rate physician-patient interaction across six domains: "clarity," "elicited concerns," "explained results," "worked together (on decision making)," "compassion and respect," and "lack of discrimination by race/ethnicity." Each is scored on a five-point scale. Frequencies of "top-box" (5/5) scores were compared for significance (p < 0.05) between HL-deficient and HL-adequate patients. RESULTS: One hundred ninety-nine patients participated. Average age was 42 years, 33% female. Forty-nine (25%) patients had deficient HL. The majority of patients in both groups rated communication below 5/5 across all domains except "compassion and respect" and "lack of discrimination by race/ethnicity." Health literacy-deficient patients were consistently less likely to give physicians top-box scores, most notably in the "elicited concerns" domain (35% vs. 54%, p = 0.012). CONCLUSION: Health literacy-deficient patients appear relatively less satisfied with physician communication, particularly with respect to perceiving that their concerns are being heard. Overall, however, the majority of patients in both groups were unlikely to score physician communication in the "top box." Efforts to improve physician-trauma patient communication are warranted, with attention directed toward meeting the needs of HL-deficient patients. LEVEL OF EVIDENCE: Prognostic/Epidemiologic, level I.

Clinical outcomes and prognostic factors of transcatheter aortic valve implantation in bicuspid aortic valve patients.

BACKGROUND: The purpose of this study was to evaluate the outcomes of transcatheter aortic valve replacement (TAVR) in patients with bicuspid aortic valve stenosis (AS). METHODS: From April 2012 and December 2016, 108 patients with bicuspid AS underwent TAVR using the Sapien XT (34 patients) and Sapien 3 (74 patients) valves. Procedural and clinical outcomes were assessed according to VARC-2 criteria and compared between the two devices. RESULTS: In the overall cohort, the majority of patients were male (71.3%) with an intermediate surgical risk and a mean Society of Thoracic Surgeons (STS) score of 5.2%. Compared to the Sapien XT group, the Sapien 3 group had a significantly lower STS score (3.3%±2.0% vs. 6.7%±3.6%; P=0.001). Compared to the Sapien XT group, the Sapien 3 group had a significantly lower rate of moderate or severe paravalvular leak (2.7% vs. 14.7%; P=0.03) and higher device success (97.3% vs. 82.4%; P=0.006). There were no significant differences between the two groups in terms of 30-day all-cause mortality, stroke, life-threatening bleeding, major vascular complication and acute kidney injury (stage 2 or 3). Cumulative all-cause mortality at 1-year follow-up was 6.9%. There were no significant differences in cumulative event rates for all-cause mortality at 1-year follow-up between the two groups (9.4% vs. 4.6%; log-rank P=0.47). By univariate analysis, major vascular complication was significantly associated with overall all-cause mortality [hazard ratios (HR): 7.57; 95% confidence interval (CI): 1.51-37.86; P=0.014]. CONCLUSIONS: TAVR using the balloon-expandable valves provided acceptable procedural and clinical outcomes in patients with bicuspid AS. The new-generation Sapien 3 valves showed improved procedural outcomes compared to the early-generation Sapien XT valves.

Relation Between Left Ventricular Outflow Tract Calcium and Mortality Following Transcatheter Aortic Valve Implantation.

Left ventricular outflow tract (LVOT) calcium is known to be associated with adverse procedural outcomes after transcatheter aortic valve implantation (TAVI), yet its effect on midterm outcomes has not been previously investigated. The aim of this study was to determine the influence of LVOT calcium on 2-year mortality after TAVI. A total of 537 consecutive patients underwent TAVI and 2 groups were established, stratified based on the severity of the LVOT calcium. The primary outcome was 2-year overall survival rate. The ≥moderate LVOT calcium group included 107 patients (19.9%) and the remaining 430 patients (80.1%) were included in the ≤mild LVOT calcium group. After a median follow-up of 717 days (interquartile range 484 to 828), the Kaplan-Meier analysis revealed that the 2-year overall survival probability was significantly lower in the ≥moderate LVOT calcium group than in the ≤mild LVOT calcium group (log-rank p = 0.001). On a Cox hazard model, ≥moderate LVOT calcium was associated with increased all-cause mortality after TAVI (hazard ratio 1.74, p = 0.009). In the subgroup analysis, based on valve designs, SAPIEN 3-TAVI done in the setting of ≥moderate LVOT calcium had a relatively similar survival probability as those of ≤mild LVOT calcium (log-rank p = 0.18), which is in contrast with older generation valves (log-rank p = 0.001). In conclusion, patients with ≥moderate LVOT calcium were shown to have a lower survival probability in the midterm follow-up after TAVI, compared with those with ≤mild LVOT calcium. Patients with high-grade LVOT calcium should be monitored with longer-term follow-ups after TAVI.

Optimal sizing for SAPIEN 3 transcatheter aortic valve replacement in patients with or without left ventricular outflow tract calcification.

AIMS: The impact of left ventricular outflow tract calcification (LVOT-CA) on SAPIEN 3 transcatheter aortic valve replacement (S3-TAVR) is not well understood. The aims of the present study were to determine optimal device sizing for S3-TAVR in patients with or without LVOT-CA and to evaluate the influence of residual paravalvular leak (PVL) on survival after S3-TAVR in these patients. METHODS AND RESULTS: This study analysed 280 patients (LVOT-CA=144, no LVOT-CA=136) undergoing S3-TAVR. Optimal annular area sizing was defined as % annular area sizing related to lower rates of ≥mild PVL. Annular area sizing was determined as follows: (prosthesis area/CT annulus area-1)×100. Overall, ≥mild PVL was present in 25.7%. Receiver operating characteristic curve analysis for prediction of ≥mild PVL in patients with LVOT-CA showed that 7.2% annular area sizing was identified as the optimal threshold (area under the curve [AUC] 0.71). Conversely, annular area sizing for no LVOT-CA appeared unrelated to PVL (AUC 0.58). Aortic annular injury was seen in four patients (average 15.5% annular area oversizing), three of whom had LVOT-CA. Although there was no difference in one-year survival between patients with ≥mild PVL and without PVL (log-rank p=0.91), subgroup analysis demonstrated that patients with ≥moderate LVOT-CA who had ≥mild PVL had lower survival compared to patients with ≥mild PVL and none or mild LVOT-CA (log-rank p=0.010). CONCLUSIONS: In the setting of LVOT-CA, an optimally sized S3 valve is required to reduce PVL and to increase survival following TAVR.
