Epidural catheters are associated with an increased risk of venous thromboembolism in trauma

Journal of Thrombosis and Thrombolysis - Little is known about the association between epidural catheters (EC) and venous thromboembolism (VTE) in trauma. We sought to study this association and...     

Gender Matters: Condom Use and Nonuse Among Behaviorally Bisexual Men

Although frequently cited as being at high risk for HIV/STI transmission, little is known about behaviorally bisexual men’s patterns and experiences of condom use and nonuse with male and female sexual partners. Using a variety of recruitment techniques informed by a Community Advisory Committee, a total of 77 behaviorally bisexual men were recruited from Indianapolis, Indiana to participate in semi-structured interviews focused on sexual health. Qualitative data were collected containing detailed information on their patterns and experiences of condom use and nonuse with both male and female partners. Participants described numerous commonly reported barriers for consistent condom use, as well as distinct bisexual-specific barriers. The majority reported consistent condom use with male and female casual partners, but many who did not use condoms described doing so in the context of ongoing relationships. In addition, participants provided reasons for condom use and nonuse that varied based on the gender of the partner and the type of relationship with the partner. Future interventions focused on increasing condom use among behaviorally bisexual men should take into account the unique complexities of gender and relationship configurations in this distinct population.     

Physician Practice Participation in Accountable Care Organizations: The Emergence of the Unicorn

Objective

To provide the first nationally based information on physician practice involvement in ACOs.

Data Sources/Study Setting

Primary data from the third National Survey of Physician Organizations (January 2012–May 2013).

Study Design

We conducted a 40-minute phone survey in a sample of physician practices. A nationally representative sample of practices was surveyed in order to provide estimates of organizational characteristics, care management processes, ACO participation, and related variables for four major chronic illnesses.

Data Collection/Extraction Methods

We evaluated the associations between ACO participation, organizational characteristics, and a 25-point index of patient-centered medical home processes.

Principal Findings

We found that 23.7 percent of physician practices (n = 280) reported joining an ACO; 15.7 percent (n = 186) were planning to become involved within the next 12 months and 60.6 percent (n = 717) reported no involvement and no plans to become involved. Larger practices, those receiving patients from an IPA and/or PHO, those that were physician-owned versus hospital/health system-owned, those located in New England, and those with greater patient-centered medical home (PCMH) care management processes were more likely to have joined an ACO.

Conclusions

Physician practices that are currently participating in ACOs appear to be relatively large, or to be members of an IPA or PHO, are less likely to be hospital-owned and are more likely to use more care management processes than nonparticipating practices.     

Does Winning a Pay-for-Performance Bonus Improve Subsequent Quality Performance? Evidence from the Hospital Quality Incentive Demonstration

Objective

To test whether receiving a financial bonus for quality in the Premier Hospital Quality Incentive Demonstration (HQID) stimulated subsequent quality improvement.

Data

Hospital-level data on process-of-care quality from Hospital Compare for the treatment of acute myocardial infarction (AMI), heart failure, and pneumonia for 260 hospitals participating in the HQID from 2004 to 2006; receipt of quality bonuses in the first 3 years of HQID from the Premier Inc. website; and hospital characteristics from the 2005 American Hospital Association Annual Survey.

Study Design

Under the HQID, hospitals received a 1 percent bonus on Medicare payments for scoring between the 80th and 90th percentiles on a composite quality measure, and a 2 percent bonus for scoring at the 90th percentile or above. We used a regression discontinuity design to evaluate whether hospitals with quality scores just above these payment thresholds improved more in the subsequent year than hospitals with quality scores just below the thresholds. In alternative specifications, we examined samples of hospitals scoring within 3, 5, and 10 percentage point “bandwidths” of the thresholds. We used a Generalized Linear Model to estimate whether the relationship between quality and lagged quality was discontinuous at the lagged thresholds required for quality bonuses.

Principal Findings

There were no statistically significant associations between receipt of a bonus and subsequent quality performance, with the exception of the 2 percent bonus for AMI in 2006 using the 5 percentage point bandwidth (0.8 percentage point increase, p < .01), and the 1 percent bonus for pneumonia in 2005 using all bandwidths (3.7 percentage point increase using the 3 percentage point bandwidth, p < .05).

Conclusions

We found little evidence that hospitals'' receipt of quality bonuses was associated with subsequent improvement in performance. This raises questions about whether winning in pay-for-performance programs, such as Hospital Value-Based Purchasing, will lead to subsequent quality improvement.     

Risk Selection into Consumer‐Directed Health Plans: An Analysis of Family Choices within Large Employers

Objective

To identify the degree of selection into consumer-directed health plans (CDHPs) versus traditional plans over time, and factors that influence choice and temper risk selection.

Data Sources/Study Setting

Sixteen large employers offering both CDHP and traditional plans during the 2004–2007 period, more than 200,000 families.

Study Design

We model CDHP choice with logistic regression; predictors include risk scores, in addition to family, choice setting, and plan characteristics. Additional models stratify by account type or single enrollee versus family.

Data Collection/Extraction Methods

Risk scores, family characteristics, and enrollment decisions are derived from medical claims and enrollment files. Interviews with human resources executives provide additional data.

Principal Findings

CDHP risk scores were 74 percent of traditional plan scores in the first year, and this difference declined over time. Employer contributions to accounts and employee premium savings fostered CDHP enrollment and reduced risk selection. Having to make an active choice of plan increased CDHP enrollment but also increased risk selection. Risk selection was greater for singles than families and did not differ between HRA and HSA-based CDHPs.

Conclusions

Risk selection was not severe and it was well managed. Employers have effective methods to encourage CDHP enrollment and temper selection against traditional plans.     

Youth Development Through Mentorship: A Los Angeles School-Based Mentorship Program Among Latino Children

Despite higher risk for school failure, few school-based mentoring (SBM) studies have focused on low-income at-risk Latino children. We describe the development and evaluation of the Youth Empowerment Program (YEP), a sustainable, high-quality, SBM program among urban Latino students. Based on evidence from work in other communities, YEP was created as a partnership between the 4th and 5th grades at a Los Angeles Title I elementary school and university undergraduates. We tested the feasibility of applying a previously validated relationship quality assessment tool in this population. Since 2008, 61 mentor and mentee pairs have participated in YEP, with an average relationship length of 1.5 years. Through 2010, over 95 % of pairs had relationships lasting at least 1 year, while 47 % lasted 2 or more years. Seventy-percent of mentees and 85 % of mentors were female, and an increased trend for early relationship termination was observed among male mentees. Through 2011, relationships lasted under 1 year among 29 % of male mentees compared to 7 % of female mentees (p = 0.15). A previously validated relationship quality assessment tool was easily incorporated into YEP, with relationships exhibiting youth-centeredness, emotional engagement and low dissatisfaction. After 5 years, YEP has become a feasible and sustainable SBM program providing long-term relationships for low-income Latino children. These relationships may improve youth health through fewer risky behaviors and attitude improvements. Future work should focus on supporting male mentors and mentees.     

Modifying attitudes to mental health using comedy as a delivery medium

Purpose

Beliefs about other people’s potential views or reactions may be powerful determinants of mental health help-seeking behaviours. United Kingdom Armed Forces (UK AF) have made considerable efforts to promote appropriate help seeking though it is often suggested that military personnel remain reluctant to seek help. This study evaluated a novel stigma-reduction method, stand-up comedy, in service personnel.

Method

Personnel viewed a regular comedy show or a show containing mental health information. Pre, immediately post-show and 3 months later, military stigmatisation, potential discrimination, mental health knowledge, help-seeking and coping behaviour, talking about mental health, current mental health and alcohol use were measured.

Results

Response rates were 81.3 % pre-show, 67.6 % post-show and 18.9 % at follow-up. Inclusion of mental health material did not appear to detract from show satisfaction. Post-show, intervention group (IG) participants reported significantly less stigmatisation and accurately answered mental health-related questions; in the small numbers followed up, neither difference was maintained, however, IG personnel were statistically significantly more likely to discuss mental health and to advise others about mental health; adjusted analyses suggested that this was related to factors other than the show.

Conclusion

In UK AF personnel, embedding mental health awareness within a comedy show format had a short-term positive effect upon military stigmatisation regarding mental health. The low rate of follow-up limited our ability to assess whether this effect was durable. If the longevity of change can be adequately assessed and demonstrated in further research, comedy could potentially form a component of a comprehensive stigma-reduction strategy.     

Regionally specific increased volume of the amygdala in Williams syndrome: Evidence from surface‐based modeling

Williams syndrome (WS) is a condition caused by a contiguous deletion of approximately 26–28 genes from chromosome 7, and is characterized by abnormal social and emotional processing and abnormal structure and function of the amygdala. Prior studies show that the amygdala is relatively enlarged in WS, but very little is known regarding the regional specificity of increased amygdalar volume in this condition. Here we investigated the regional specificity of structural alterations of the amygdala in WS, compared to a typically developing (TD) control group. We acquired high resolution brain MRI data from 79 participants (39 WS, 40 TD) and used a surface‐based analytical modeling approach. The WS group exhibited several areas of increased radial expansion of the amygdalar surface and no areas of decreased radial expansion of the amygdalar surface compared to TD controls. The areas found to exhibit particularly increased radial expansion in WS included the bilateral posterior cortical nucleus, lateral nucleus, and the central nucleus. This greater regional and anatomical specificity of altered amygdala structure in WS contributes to a model relating genetic risk in WS to the development of key brain regions for social and emotional functioning.
