Assessing the 16 hour intern shift limit: Results of a multi-center, mixed-methods study of residents and faculty in general surgery.

BACKGROUND: The study explores how residents and faculty assess the ACGME's 16-h limit on intern shifts. METHODS: Questionnaire response rates were 76% for residents (N = 291) and 71% for faculty (N = 279) in 13 general surgery residency programs. Results include means, percentage in agreement, and statistical tests for 15 questionnaire items. Semi-structured interviews conducted with 39 residents and 43 faculty were analyzed for main themes. RESULTS: Few view the intern shift limit as a positive change. Views differ (P < 0.01) for residents and faculty on 12 of 15 item means and across PGY levels on all 15 items. Interviews indicate concerns about losses with respect to education and professional development, difficulties when interns transition to their second year, and how intern shifts may be more fatiguing than expected. CONCLUSIONS: The 16-h limit on intern shifts has remained a source of concern and an educational challenge for residents and faculty.

The promise and problems of non-physician practitioners in general surgery education: Results of a multi-center, mixed-methods study of faculty.

BACKGROUND: Nurse Practitioners and Physician Assistants - called non-physician practitioners or NPPs - are common, but little is known about their educational promise and problems. METHODS: General surgery faculty in 13 residency programs were surveyed (N = 279 with a 71% response rate) and interviewed (N = 43) about experiences with NPPs. The survey documents overall patterns and differences by program type and primary service; interviews point to deeper rationales and concerns. RESULTS: NPPs reduce faculty and resident workloads and teach residents. NPPs also reduce resident exposure to educationally valuable activities, and faculty sometimes round, make decisions, and operate with NPPs instead of residents. Interviews indicate that NPPs can overly reduce resident involvement in patient care, diminish resident responsibility and decision making, disrupt team dynamics, and compete for procedures. CONCLUSIONS: NPPs both enhance and hinder surgical education and highlight the need to more clearly articulate learning outcomes for residents and activities necessary to achieve those outcomes.

Do international rotations make surgical residents more resource-efficient? A preliminary study.

OBJECTIVE: Interest in international surgery among general surgery residents in the United States has been shown in several publications. Several general surgery residency programs have reported their experiences with international surgery rotations (ISRs). Learning to use limited resources more efficiently is often cited as a benefit of such rotations. We hypothesized that general surgery residents become more resource efficient after they have completed an ISR. STUDY DESIGN: Laboratory, radiologic, and diagnostic studies ordered on 2900 patients by 21 general surgery residents over 65 months at a single institution were analyzed retrospectively. The patient populations they wrote orders on were assessed for similarity in age, gender, and diagnoses. The outcomes in those patient populations were assessed by duration of stay and in-hospital mortality. Six (29%) of these residents (ISR residents) completed a 1-month ISR during their third year of residency. Their orders were compared with their classmates who did not participate in an ISR (NISR residents). The results were compared between the 2 cohorts from both before and after their international rotations. An analysis focused on comparing the changes from pre-ISR to post-ISR. A survey was also sent after objective data were collected to all residents and alumni involved in the study to assess their subjective perception of changes in their resource efficiency and to characterize their ISRs. RESULTS: Patient populations were similar in terms of demographics and diagnoses. ISR residents generated an average of $122 less in orders per patient per month after their ISR compared with before. NISR residents generated an average of $338 more in orders per patient per month after the ISRs compared with before (p = 0.04). Pre-ISR order charges were statistically similar. Similar results were observed when radiologic/diagnostic study orders were analyzed independently. Differences in outcomes were statistically insignificant. The survey revealed that most of the ISR residents perceived that their attitude toward ordering tests and laboratories was influenced greatly by their ISR, and all the ISR residents perceived that they became more resource efficient than their peers after their ISRs. CONCLUSION: These preliminary findings seem to indicate increased resource efficiency among general surgery residents who completed an ISR. However, the sample size of residents was small, and we could not establish conclusively a causal relationship to their ISRs. A more extensive study is needed if reliable conclusions are to be drawn regarding the effect of ISRs on the resource efficiency of residents.

Mammographic distance as a predictor of nipple-areola complex involvement in breast cancer.

BACKGROUND: Although involvement of the nipple-areola complex (NAC) occurs in a minority of patients with breast cancer, standard skin-sparing mastectomy requires its removal. To assist in patient selection for NAC preservation we evaluated NAC involvement and correlated this with preoperatively available clinical data. METHODS: Patients with invasive breast cancer or ductal carcinoma in situ undergoing mastectomy from 1998 to 2005 were reviewed retrospectively. The NAC had been evaluated with multiple thin sections. Pathologic data including NAC involvement were analyzed. The mammographic tumor distance from the nipple was measured in 2 standard views. RESULTS: There were 302 patients enrolled, of which 10% were noted to have NAC involvement. This correlated negatively with tumor distance from the nipple (P < .05). A logistic regression equation was derived from the data, with NAC involvement as the dependent variable and distance from the nipple as the independent variable. The equation predicted involvement of the NAC when the distance was less than 4.96 cm with a sensitivity of 82% and a negative predictive value of 97%. CONCLUSIONS: A majority of patients are candidates for NAC preservation. The mammographic distance between the tumor and the nipple is independently predictive of NAC involvement and is useful as an equation variable.
