Guidelines for Maintaining a Professional Compass in the Era of Social Networking

Matthew P. Landman; Julia Shelton; Rondi M. Kauffmann; Jeffery B. Dattilo

OBJECTIVES The use of social networking (SN) sites, such as Facebook and Twitter, has skyrocketed during the past 5 years, with more than 400 million current users. What was once isolated to high schools or college campuses has become increasingly ubiquitous in everyday life and across a multitude of industries. Medical centers and residency programs are not immune to this invasion. These sites present opportunities for the rapid dissemination of information from status updates, to tweets, to medical support groups, and even clinical communication between patients and providers. Although powerful, this technology also opens the door for misuse and policies for use will be necessary. We strive to begin a discourse in the surgical community in regard to maintaining professionalism while using SN sites. RESULTS The use of SN sites among surgical house staff and faculty has not been addressed previously. To that end, we sought to ascertain the use of the SN site Facebook at our residency program. Of 88 residents and 127 faculty, 56 (64%) and 28 (22%), respectively, have pages on Facebook. Of these, 50% are publicly accessible. Thirty-one percent of the publicly accessible pages had work-related comments posted, and of these comments, 14% referenced specific patient situations or were related to patient care. CONCLUSIONS Given the widespread use of SN websites in our surgical community and in society as a whole, every effort should be made to guard against professional truancy. We offer a set of guidelines consistent with the Accreditation Council for Graduate Medical Education and the American College of Surgeons professionalism mandates in regard to usage of these websites. By acknowledging this need and by following these guidelines, surgeons will continue to define and uphold ethical boundaries and thus demonstrate a commitment to patient privacy and the highest levels of professionalism.

Reduction in Corticosteroids Is Associated with Better Health-Related Quality of Life after Liver Transplantation

BACKGROUND Corticosteroid use during post-transplant immunosuppression contributes to documented long-term complications in liver transplant recipients. However, the effects of steroids on post-transplant physical and mental health-related quality of life (HRQOL) have not been established. We aimed to test the association between steroid-based immunosuppression and post-transplant HRQOL in liver transplant recipients. STUDY DESIGN We performed a retrospective analysis of prospective, longitudinal HRQOL measured using the Short Form 36 Health Survey physical and mental component summary scores, Beck Anxiety Inventory, and Center for Epidemiologic Studies Depression Scale. Steroid use (none, low [<10 mg/d], high [≥10 mg/d]) and temporally associated acute rejection (within previous 6 weeks, previous 7 to 12 weeks, and never or >12 weeks before HRQOL measurement) were determined at every post-transplant HRQOL data point. Linear mixed-effects models tested the effects of contemporaneous steroid use and dosing on post-transplant HRQOL. RESULTS The sample included 186 adult liver transplant recipients (mean age 54 ± 8 years, 70% male) with pre- and at least 1 post-transplant HRQOL data point. Individual follow-up post-transplant averaged 21 ± 18 months (range 1 to 74 months). After controlling for pre-transplant HRQOL, time post-transplant, pre-transplant diagnosis group, and temporally associated episodes of rejection, post-transplant high-dose steroid use (≥10 mg/d) was associated with lower physical component summary (p < 0.001) and mental component summary (p = 0.049) scores and increased Beck Anxiety Inventory (p = 0.015) scores. Low-dose steroid use (<10 mg/d) was not associated with post-transplant HRQOL in any model (all p ≥ 0.28). CONCLUSIONS High-dose steroid use for post-transplant immunosuppression in liver transplant recipients was associated with reduced physical and mental HRQOL, and increased symptoms of anxiety. There was an association between better HRQOL and steroid reduction to <10 mg/d in liver transplant recipients during a broad follow-up period.

A Cost-Effectiveness Analysis of Early vs Late Reconstruction of Iatrogenic Bile Duct Injuries

BACKGROUND Controversy exists regarding the optimal timing of repair after iatrogenic bile duct injuries (BDI). Several studies advocate late repair (≥6 weeks after injury) with mandatory drainage and resolution of inflammation. Others indicate that early repair (<6 weeks after injury) produces comparable or superior clinical outcomes. Additionally, although most studies have reported inferior outcomes with primary surgeon repair, this practice continues. With disparate published recommendations and rising health care costs, decision analysis was used to examine the cost-effectiveness of BDI repair. STUDY DESIGN A Markov model was developed to evaluate primary surgeon repair (PSR), late repair by a hepatobiliary surgeon (LHBS), and early repair by a hepatobiliary surgeon (EHBS). Baseline values and ranges were collected from the literature. Sensitivity analsyses were conducted to test the strength of the model and variability of parameters. RESULTS The model demonstrated that EHBS was associated with lower costs, earlier return to normal activity, and better quality of life. Specifically, 1 year after repair, PSR yielded 0.53 quality adjusted life years (QALYs) (

48,000/QALY). Sensitivity analyses supported these findings at clinically meaningful probabilities. CONCLUSIONS This cost-effectiveness model demonstrates that early repair by a hepatobiliary surgeon is the superior strategy for the treatment of BDI in properly selected patients. Although there is little clinical difference between early and late repair, there is a great difference in cost and quality of life. Ideally, costs and quality of life should be considered in decisions regarding strategies of repair of injured bile ducts.

The long-term effect of bile duct injuries on health-related quality of life: a meta-analysis

BACKGROUND Live donor kidney transplantation is the treatment of choice for end-stage renal disease. Open donor nephrectomy (ODN) was the standard until the introduction of the laparoscopic donor nephrectomy (LDN) in 1995. Hand-assisted laparoscopic donor nephrectomy (HALDN) was added shortly thereafter. The laparoscopic techniques are associated with increased operating room times and equipment costs; however, these techniques speed patient return to normal activity. The aim of this study is to evaluate the cost of these techniques. MATERIALS AND METHODS A decision analysis model was developed to simulate outcomes for donors undergoing ODN, LDN, and HALDN. Outcomes were simulated from both the institutional perspective (IP) and the societal perspective (SP). Baseline values and ranges were determined from a systematic review of the literature. Sensitivity analyses were conducted to test model strength. RESULTS From the IP, ODN is the least costly strategy with a cost of
