PURPOSE

In addition to excellent patient care, the focus of academic medicine has traditionally been resident training. The changing landscape of health care has placed increased focus on objective outcomes. As a result, the surgical training process has come under scrutiny for its influence on patient care. We elucidated the effect of resident involvement on patient outcomes.

MATERIALS AND METHODS

We retrospectively analyzed data from the 2005 to 2011 NSQIP® participant use database. Patients were separated into 2 cohorts by resident participation vs no participation. The cohorts were compared based on preoperative comorbidities, demographic characteristics and intraoperative factors. Confounders were adjusted for by propensity score modification and complications were analyzed using perioperative variables as predictors.

RESULTS

A total of 40,001 patients met study inclusion criteria. Raw data analysis revealed that cases with resident participation had a higher rate of overall complications. However, after propensity score modification there was no significant difference in overall, medical or surgical complications in cases with resident participation. Resident participation was associated with decreased odds of overall complications (0.85). Operative time was significantly longer in cases with resident participation (159 vs 98 minutes).

CONCLUSIONS

Urology resident involvement is not associated with increased overall and surgical complications. It may even be protective when adjusted for appropriate factors such as case mix, complexity and operative time.

BACKGROUND

Knowledge of nasal carriage is important in predicting staphylococcal infection, and no information exists regarding the endemicity of Staphylococcus aureus in Haiti.

METHODS

We performed a cross-sectional analysis of S. aureus nasal screening in an acute care, a subacute rehabilitation, and a community setting, with a brief medical and epidemiological history. PCR-positive S. aureus screening nasal cultures underwent molecular analysis for spa type, SCCmec type, and virulence genes (Panton-Valentine leukocidin (PVL), toxic shock syndrome toxin (TSST), and arginine catabolic mobile element (ACME)), and were evaluated for antibiotic susceptibility using commercial tests.

RESULTS

Overall carriage rates of 8.4% methicillin-susceptible S. aureus (MSSA) and 2.8% methicillin-resistant S. aureus (MRSA) were identified, with a high rate of tetracycline resistance. TSST and PVL genes were identified in MSSA. MRSA isolates contained no virulence markers. Unique MSSA phenotypes (i.e., linezolid-resistant, vancomycin-sensitive/daptomycin non-susceptible) were identified, as were two PVL-positive ST152 MSSA colonization isolates, previously geographically limited to Africa.

CONCLUSIONS

We found a low S. aureus carriage rate with complete vancomycin susceptibility and high tetracycline resistance, which has important public health implications with regard to treatment. Additionally, the finding of PVL-positive MSSA isolates, including the expansion of a previously described limited 'divergent' clone, ST152, warrants further evaluation.

Children whose mothers are victims of intimate partner violence (IPV) are at increased risk of adverse health and psychosocial consequences, including becoming victims or perpetrators of violence in their own relationships. This study aimed to understand the role mothers may play in preventing the perpetuation of violence in their children's lives. We performed semistructured interviews with 18 IPV victims who are mothers and were living at the Women's Center & Shelter of Greater Pittsburgh from July through November 2011. We sought to understand how they communicate with their children about IPV and relationships. These mothers described a desire to explain their IPV experience and offer advice about avoiding violence in relationships. As foundations for these discussions, they emphasized the importance of close relationships and open communication with their children. Although mothers are interested in talking about IPV and relationships and identify communication strategies for doing so, many have never discussed these topics with their children. These mothers need and want an intervention to help them learn how to communicate with their children to promote healthy relationships. Development of a program to facilitate communication between IPV victims and their children could create an important tool to empower mothers to break the cross-generational cycle of domestic violence.

CONTEXT

The burden of injuries to college ultimate players has never been fully described.

OBJECTIVE

To quantify the injury rate in ultimate players and describe the diagnoses, anatomic locations, and mechanisms of injuries.

DESIGN

Descriptive epidemiology study.

SETTING

College ultimate teams in the United States during the 2012 season.

MAIN OUTCOME MEASURE(S)

Initial injury rate per 1000 athlete-exposures.

RESULTS

The initial injury rate in college ultimate players was 12.64 per 1000 athlete-exposures; the rate did not differ between men and women (P = .5). Bivariate analysis indicated that injuries occurred twice as often during games as during practices, men were more likely than women to be injured when laying out for the disc, and men were more likely to incur strains and sprains than women.

CONCLUSIONS

Injury patterns to college ultimate players were similar to those for athletes in other National Collegiate Athletic Association sports. This is the first study to systematically describe injuries to ultimate players.

PURPOSE

Previous studies analyzing the relationship between Body Mass Index (BMI) and complications after partial nephrectomy have been underpowered. We use a national surgical database to explore the association of BMI with postoperative outcomes for Open Partial Nephrectomy (OPN) and Minimally Invasive Partial Nephrectomy (MIPN).

PATIENTS AND METHODS

Years 2005-2012 of the National Surgical Quality Improvement Program (NSQIP) were queried for OPN and MIPN. Postoperative complications were organized according to Clavien Grades and compared across normal weight (BMI kg/m(2)=18.5-<25.0), overweight (BMI=25.0-<30.0), and obese (BMI≥30.0) patients using standard descriptive statistics and multivariate regression modeling.

RESULTS

Of 1667 OPNs and 2018 MIPNs, 46.2% of patients were obese. Operative time was 16.91 minutes longer on average for obese patients (p<0.001). The overall complication rate after OPN was 17.9%, 17.2%, and 17.9% (p=0.945) for normal weight, overweight, and obese patients, respectively; while the overall complication rate after MIPN was 6.9%, 6.3%, and 8.7% (p=0.147). Multivariate regression analysis demonstrated that overweight and obese patients were not at increased risk for any complication grade after OPN and MIPN compared to normal weight patients. When comparing procedures, MIPN had a lower complication rate compared to OPN for obese (8.7% vs 17.9%, p<0.001) and morbidly obese patients (9.2% vs 22.2%, p=0.001).

CONCLUSIONS

Although surgery in obese patients is longer compared to normal weight patients, it does not appear to increase the likelihood of 30-day postoperative complications for OPN or MIPN. However, obese patients undergoing MIPN had lower complication rates than those undergoing OPN.
