The effects of preoperative cardiology consultation prior to elective abdominal aortic aneurysm repair on patient morbidity.

Objectives The relationship between preoperative medical consultations and postoperative complications has not been extensively studied. Thus, we investigated the impact of preoperative consultation on postoperative morbidity following elective abdominal aortic aneurysm repair. Methods A retrospective review was conducted on 469 patients (mean age 72 years, 20% female) who underwent elective abdominal aortic aneurysm repair from June 2007 to July 2014. Data elements included detailed medical history, preoperative cardiology consultation, and postoperative complications. Primary outcomes included 30-day morbidity, consult-specific morbidity, and mortality. A bivariate probit regression model accounting for the endogeneity of binary preoperative medical consult and patient variability was estimated with a maximum likelihood function. Results Eighty patients had preoperative medical consults (85% cardiology); thus, our analysis focuses on the effect of cardiac-related preoperative consults. Hyperlipidemia, increased aneurysm size, and increased revised cardiac risk index increased likelihood of referral to cardiology preoperatively. Surgery type (endovascular versus open repair) was not significant in development of postoperative complications when controlling for revised cardiac risk index ( p = 0.295). After controlling for patient comorbidities, there was no difference in postoperative cardiac-related complications between patients who did and did not undergo cardiology consultation preoperatively ( p = 0.386). Conclusions When controlling for patient disease severity using revised cardiac risk index risk stratification, preoperative cardiology consultation is not associated with postoperative cardiac morbidity.

Velopharyngeal Dysfunction and Sleep Apnea-A Survey to Ascertain Surgical Practice Patterns.

OBJECTIVE: To determine if all cleft surgeons uniformly and adequately evaluate patients with cleft for obstructive sleep apnea (OSA) and consider OSA in treatment of velopharyngeal dysfunction (VPD). DESIGN: A 22-question survey was administered via e-mail to 1117 surgeons who were members of the American Cleft Palate-Craniofacial Association. Logistic regression was used to determine if management was affected by years in practice, clinical volume, field of training, and region of practice. MAIN OUTCOME MEASURES: We sought to determine if years in practice, clinical volume, region of practice, and surgical specialty affected surgeons' evaluation of OSA and their approaches to VPD. RESULTS: A total of 231 surgeons responded (21% response rate), and 67% stated that they had trained in plastic surgery. With increasing years of practice, surgeons were less likely to refer patients for preoperative and postoperative sleep studies (P = .00 and P = .001, respectively), screen patients for sleep apnea (P = .008), or change their management based on a sleep study (P = .001). There were no significant differences in screening or testing for OSA based upon clinical volume. Among those surveyed, otolaryngologists were more likely to refer patients for postoperative sleep studies (P = .028). Surgeons in the Southeast were more likely to change their management based upon a sleep study (P = .038). CONCLUSIONS: Statistically significant trends in screening and testing for OSA in the setting of VPD were identified by this survey. Notably, older surgeons were less likely to investigate OSA in their patients, and not all specialties equally refer for postoperative sleep studies.

Progressive Entrustment to Achieve Resident Autonomy in the Operating Room: A National Qualitative Study With General Surgery Faculty and Residents.

OBJECTIVE: The purpose of this study was to identify behaviors that faculty and residents exhibit during intraoperative interactions, which support or inhibit progressive entrustment leading to operative autonomy. BACKGROUND: In the operating room, a critical balance is sought between direct faculty supervision and appropriate increase in resident autonomy with indirect faculty supervision. Little is known regarding perspectives of faculty and residents about how attendings increasingly step back and safely delegate autonomy to trainees. Understanding the context in which these decisions are made is critical to achieving a safe strategy for imparting progressive responsibility. METHODS: A qualitative study was undertaken from January 2014 to February 2015. Semistructured interviews were conducted with 37 faculty and 59 residents from 14 and 41 institutions, respectively. Participants were selected using stratified random sampling from general surgery residency programs across the United States to represent a range of university, university-affiliated, and community programs, and geographic regions. Audio recordings of interviews were transcribed, iteratively analyzed, and emergent themes identified. RESULTS: Six themes were identified as influencing progressive entrustment in the operating room: optimizing faculty intraoperative feedback; policies and regulations affecting role of resident in the operating room; flexible faculty teaching strategies; context-specific variables; leadership opportunities for resident in the case; and safe struggle for resident when appropriate. CONCLUSIONS: Perspectives of faculty and residents while overlapping were different in emphasis. Better understanding faculty-resident interactions, individual behaviors, contextual influences, and national regulations that influence intraoperative education have the potential to significantly affect progressive entrustment in training paradigms.

Maxillomandibular Advancement Surgery for Patients Who Are Refractory to Continuous Positive Airway Pressure: Are There Predictors of Success?

PURPOSE: This pilot study was conducted to determine the effectiveness of maxillomandibular advancement (MMA) in the treatment of patients with moderate to severe obstructive sleep apnea (OSA). The predictive value of clinical, radiographic, and treatment-related variables also was investigated in relation to the success or failure of MMA as treatment for OSA. MATERIALS AND METHODS: A retrospective study design was used to assess the outcomes of MMA in patients with moderate to severe OSA (apnea hypopnea index [AHI] >15 events per hour) at the University of Michigan (Ann Arbor, MI). Data collected included clinical, radiographic, and polysomnographic findings. Primary outcomes of interest included the AHI, minimal oxygen saturation, and percentage of time spent with oxygen saturation lower than 88% as measured by polysomnography. RESULTS: Twenty patients met the inclusion criteria for the study (mean age, 48.8 ± 12.3 yr). Mean body mass index decreased from 32.03 ± 5.13 kg/m2 at baseline to 29.75 ± 5.23 kg/m2 at follow-up (P = .001). Mean advancements were 13.5 ± 2.7 mm at point B and 16.1 ± 4.5 mm at the pogonion. A 4.5-fold increase in minimal cross-sectional area and a 2.2-fold increase in airway volume were achieved on average. Patients showed a 68.5% decrease in mean AHI from 49.4 to 15.6 events per hour (P < .001). The percentage of time with oxygen saturation lower than 88% was significantly decreased from 15.4% at baseline to 1.4% after surgery (P = .014). The overall surgical success rate was 55% (11 of 20) based on an AHI of fewer than 15 events per hour. CONCLUSIONS: These preliminary results indicate that MMA surgery might be highly effective for select patients with moderate to severe OSA. Despite large increases in airway dimensions, a surgical success rate of 55% was achieved in the overall sample. Assessment of predictive variables for success and failure are discussed.

Teaching across the continuum: variations in rankings and valued teaching components between surgery residents and medical students.

BACKGROUND: Surgical faculty teach medical students and residents within the same environment; however, each group may require different teaching methods. The aim of this study was to identify teaching components valued by these sets of learners. METHODS: Teaching evaluations for 43 surgical faculty members who received yearly evaluations from students and residents were analyzed. Highest and lowest ranked educators in medical student evaluations were traced to corresponding rankings in resident evaluations. Thematic analysis was conducted on written comments. RESULTS: Educators rated the highest in the medical student group were spread out among the residents' rankings, with several educators being rated the lowest. Similar patterns were observed in reverse for faculty rated highly by residents. CONCLUSIONS: Residents and medical students value faculty teaching using different criteria, with residents more focused on operative autonomy and medical students focused on approachability. Using one group to define best teaching methods is insufficient as learners value different optimal attributes.

Metopic Craniosynostosis: A Demographic Analysis Outside an Urban Environment.

BACKGROUND: Metopic craniosynostosis has traditionally been cited as the third most common type of isolated synostosis, after sagittal and coronal craniosynostosis. Recently, several urban institutions have observed an increase in the incidence of metopic synostosis. The authors sought to determine if similar demographic changes have occurred in a more suburban setting and if so, what specific variables were associated with this change. METHODS: Patients who underwent operative correction of craniosynostosis between 1989 and 2014 were retrospectively reviewed. The type of craniosynostosis as well as sex, family history, birth history, and other demographic data were recorded. Kendall-Mann trend tests and multinomial logistic regressions were conducted, and marginal effects were calculated for all variables included in the model. RESULTS: Records of 493 patients were reviewed. Using Kendall-Mann trend tests, it was determined that metopic, sagittal, and lambdoid craniosynostoses all demonstrated an increase in incidence. Based on raw data, metopic synostosis was found to be the second most common type of craniosynostosis between 2004 and 2014. Male sex and multiple gestations were both associated with metopic craniosynostosis. CONCLUSIONS: This study demonstrated an increasing incidence of metopic craniosynostosis over time, which ascended to the second most common type of synostosis in an analysis outside of an urban environment. In our study, male sex and multiple gestation were positively associated with an increased risk of metopic craniosynostosis. Prospective studies are needed to further delineate the evolving characteristics of this patient population.
