Quadrimodal Distribution of Death after Trauma: Predictors of Death in the Fourth Peak

Introduction: Patterns of death after trauma are changing due to diagnostic and treatment advances. We examined mortality in critically injured patients at risk of death after discharge. Methods: We reviewed all critically injured (Injury Severity Score≥25 AND death in Emergency Room , death within 24hrs, OR ICU admission\u3e24hrs) adults (age≥18) admitted to a Level 1 trauma center (01/01/2000-12/31/2010) and determined death post-discharge (Social Security Death Index) of patients discharged alive. We compared demographics, injury data, and critical care resource utilization between those who died during follow-up and survivors using univariate tests and Cox proportional hazards models. Results: Of 1,695 critically injured patients, 1135 (67%) were discharged alive. As of 05/1/2012, 977 (58%) index survivors were alive (median follow-up 62mos (IQR35,96)). Of 158 deaths post-discharge, 75 (47%) occurred within the first year. Patients who died post-discharge had longer hospital (24dys (IQR13,38) vs. 17dys (IQR10,27)) and ICU LOS (17dys (IQR6,29) vs. 8dys (IQR4,19)) and were more likely to undergo tracheostomies (36.1% vs. 15.6%, p16dys increased risk of death at one year (HR1.94 (1.22,3.06)) and by the end of follow-up (HR2.19 (1.58,3.04)) compared to shorter ICU stays. Conclusion: We propose the first year after discharge as the fourth peak of trauma related mortality. Duration of ICU LOS during index hospitalization is associated with post-discharge mortality

Microvascular response to transfusion in elective spine surgery

AIM: To investigate the microvascular (skeletal muscle tissue oxygenation; SmO2) response to transfusion in patients undergoing elective complex spine surgery. METHODS: After IRB approval and written informed consent, 20 patients aged 18 to 85 years of age undergoing \u3e 3 level anterior and posterior spine fusion surgery were enrolled in the study. Patients were followed throughout the operative procedure, and for 12 h postoperatively. In addition to standard American Society of Anesthesiologists monitors, invasive measurements including central venous pressure, continual analysis of stroke volume (SV), cardiac output (CO), cardiac index (CI), and stroke volume variability (SVV) was performed. To measure skeletal muscle oxygen saturation (SmO2) during the study period, a non-invasive adhesive skin sensor based on Near Infrared Spectroscopy was placed over the deltoid muscle for continuous recording of optical spectra. All administration of fluids and blood products followed standard procedures at the Hospital for Special Surgery, without deviation from usual standards of care at the discretion of the Attending Anesthesiologist based on individual patient comorbidities, hemodynamic status, and laboratory data. Time stamps were collected for administration of colloids and blood products, to allow for analysis of SmO2 immediately before, during, and after administration of these fluids, and to allow for analysis of hemodynamic data around the same time points. Hemodynamic and oxygenation variables were collected continuously throughout the surgery, including heart rate, blood pressure, mean arterial pressure, SV, CO, CI, SVV, and SmO2. Bivariate analyses were conducted to examine the potential associations between the outcome of interest, SmO2, and each hemodynamic parameter measured using Pearson\u27s correlation coefficient, both for the overall cohort and within-patients individually. The association between receipt of packed red blood cells and SmO2 was performed by running an interrupted time series model, with SmO2 as our outcome, controlling for the amount of time spent in surgery before and after receipt of PRBC and for the inherent correlation between observations. Our model was fit using PROC AUTOREG in SAS version 9.2. All other analyses were also conducted in SAS version 9.2 (SAS Institute Inc., Cary, NC, United States). RESULTS: Pearson correlation coefficients varied widely between SmO2 and each hemodynamic parameter examined. The strongest positive correlations existed between ScvO2 (P = 0.41) and SV (P = 0.31) and SmO2; the strongest negative correlations were seen between albumin (P = -0.43) and cell saver (P = -0.37) and SmO2. Correlations for other laboratory parameters studied were weak and only based on a few observations. In the final model we found a small, but significant increase in SmO2 at the time of PRBC administration by 1.29 units (P = 0.0002). SmO2 values did not change over time prior to PRBC administration (P = 0.6658) but following PRBC administration, SmO2 values declined significantly by 0.015 units (P \u3c 0.0001). CONCLUSION: Intra-operative measurement of SmO2 during large volume, yet controlled hemorrhage, does not show a statistically significant correlation with either invasive hemodynamic, or laboratory parameters in patients undergoing elective complex spine surgery

Understanding the Experience and Evaluating the Occurrence of Depression in a Sample of Pregnant Veterans

Background: The Veterans Health Administration (VHA) encourages depression screening and treatment for pregnant veterans; however, rates of depression symptoms and treatment utilization during pregnancy have not been well-studied. Methods: We used data from the Maternity Care Coordination for Women Veterans cohort study. Specifically, our aims were to: 1) examine rates and correlates of depression symptoms in a sample of pregnant veterans; 2) understand mental health care treatment utilization and explore the experiences of veterans accessing mental health care at the VHA during pregnancy; and 3) examine VHA mental health provider\u27s perspectives on depression screening and treatment in the perinatal period. Findings: Depression symptoms were present in 28% of pregnant veterans in our sample. Social support and employment decreased odds of symptoms; history of anxiety, antidepressant use, and active duty service resulted in increased odds of symptoms. Nearly 70% of women veterans with prenatal depression symptoms received at least one mental health visit or antidepressant prescription during pregnancy. However, symptomatic pregnant women without a history of depression were less likely to receive care. Mental health providers identified absence of screening protocols and referral procedures and variability in risk/benefit conversations surrounding antidepressant use as areas of weakness for VHA mental health care during the perinatal period. Conclusions: Depression symptoms were present in nearly one in every three pregnant veterans. Depression treatment during pregnancy is complex, requiring individualized care. Policies for depression screening, referrals to providers, and medication review could be better encouraged to improve standardized care across the VHA

Venous thromboembolism in patients with prior stroke

Patients with prior stroke are susceptible to venous thromboembolism (VTE). We studied patients with stroke in the Worcester VTE study of 2488 consecutive patients hospitalized with VTE. In all, 288 (11.6%) had a clinical history of stroke and 2200 (88.4%) did not. Patients with stroke were more likely to die inhospital (9.2% vs 4%) and within 30 days of VTE diagnosis (16.7% vs 6.9%) compared with patients without stroke (all P \u3c .001). Recent immobilization (adjusted odds ratio [OR] 2.15; 95% confidence interval [CI] 1.15-4.09) and inferior vena cava (IVC) filter insertion (adjusted OR 2.1; 95% CI 1.15-3.83) were associated with a doubling of inhospital death. Recent immobilization (adjusted OR 1.84; 95% CI 1.19-2.83) and IVC filter insertion (adjusted OR 1.94; 95% CI 1.2-3.14) were associated with an increased risk of death within 30 days of VTE. In conclusion, patients with VTE and prior stroke were more than twice as likely to die while hospitalized and within 30 days of VTE diagnosis

Understanding VA\u27s Use of and Relationships With Community Care Providers Under the MISSION Act

BACKGROUND: Congress has enacted 2 major pieces of legislation to improve access to care for Veterans within the Department of Veterans Affairs (VA). As a result, the VA has undergone a major transformation in the way that care is delivered to Veterans with an increased reliance on community-based provider networks. No studies have examined the relationship between VA and contracted community providers. This study examines VA facility directors\u27 perspectives on their successes and challenges building relationships with community providers within the VA Community Care Network (CCN). OBJECTIVES: To understand who VA facilities partner with for community care, highlight areas of greatest need for partnerships in various regions, and identify challenges of working with community providers in the new CCN contract. RESEARCH DESIGN: We conducted a national survey with VA facility directors to explore needs, challenges, and expectations with the CCN. RESULTS: The most common care referred to community providers included physical therapy, chiropractic, orthopedic, ophthalmology, and acupuncture. Open-ended responses focused on 3 topics: (1) Challenges in working with community providers, (2) Strategies to maintain strong relationships with community providers, and (3) Re-engagement with community providers who no longer provide care for Veterans. CONCLUSIONS: VA faces challenges engaging with community providers given problems with timely reimbursement of community providers, low (Medicare) reimbursement rates, and confusing VA rules related to prior authorizations and bundled services. It will be critical to identify strategies to successfully initiate and sustain relationships with community providers

Bridging the Gap for Perinatal Veterans: Care by Mental Health Providers at the Veterans Health Administration

BACKGROUND: Pregnant women veterans receive maternity care from community obstetricians but continue to receive mental health care within the Veterans Health Administration (VHA). Our objective was to explore the experiences of VHA mental health providers with pregnant and postpartum veterans. METHODS: Mental health providers (n = 33) were identified at 14 VHA facilities across the United States. Semistructured interviews were conducted over the phone to learn about provider experiences with perinatal women veterans and their perceptions of depression screening and mental health treatment management for pregnant and postpartum veterans receiving mental health care within the VHA system. FINDINGS: Providers identified an absence of screening protocols and referral procedures and variability in risk/benefit conversations surrounding psychotropic medication use as important areas of weakness for VHA mental health care during the perinatal period. Care coordination within facilities, primarily through Primary Care-Mental Health Integration teams, was identified as a main facilitator to promoting better mental health care for perinatal veterans. CONCLUSIONS: Mental health providers caring for veterans during the perinatal period identified several areas where care could be improved, notably in screening and referral processes. A refinement to current guidelines to specify standard screening tools, screening schedules, and referral processes could potentially engage a greater number of pregnant women in VHA mental health care

Improving Pregnancy Outcomes through Maternity Care Coordination: A Systematic Review

BACKGROUND: Care during pregnancy is multifaceted and often goes beyond traditional prenatal care from an obstetrical care provider. Coordinating care between multiple providers can be challenging, but is beneficial for providers and patients. Care coordination is associated with decreased costs, greater patient satisfaction, and a reduction in medical errors. To our knowledge, no previous review has examined maternity care coordination (MCC) programs and their association with pregnancy outcomes. METHODS: Using a search algorithm comprised of relevant MCC terminology, studies were identified through a systematic search of PubMed, Scopus, ClinicalTrials.gov, and Google Scholar. Studies meeting eligibility criteria (e.g., defining the care coordination components and examining at least one quantitative outcome) were fully abstracted and quality rated using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist. MAIN FINDINGS: Thirty-three observational studies of MCC were included in this review. Quality scores ranged from 27% to 100%. Most studies included strategies with a team approach to decision making and/or individual case management. Social service referrals to outside organizations were also common. Twenty-seven studies reported infant birth weight as a main outcome; 12 found a significant improvement in birth weights among care coordination participants. CONCLUSIONS: Roughly one-third of the included studies reported improved birth weights among care coordination participants. However, it remains unknown what effect care coordination strategies have on patient and provider satisfaction in the prenatal care setting, two aspects of maternity care that may advance the quality and utilization of prenatal health services

Semen Quality Parameters Among U.S. Veterans of Operation Enduring Freedom, Operation Iraqi Freedom, and Operation New Dawn

BACKGROUND: There is little research investigating exposures that occurred during war or conflict and the resulting influence on semen quality. We examined the associations between military service and semen quality among U.S. Veterans of Operation Enduring Freedom, Operation Iraqi Freedom, and Operational New Dawn. METHODS: U.S. Veterans (n = 714), who sought fertility treatment and were participants of the Department of Veterans Affairs Women Veterans Cohort Study were included in the current study. Semen quality parameters (semen volume, total sperm count, sperm concentration, and percentage of total motile sperm) measured at fertility clinics in Veterans Affairs Healthcare System were analyzed. FINDINGS: The median values of Veterans were 2.7 mL for semen volume, 55.3 x 10(6) for total sperm count, 22.0 x 10(6)/mL for sperm concentration, and 55% for total motile sperm. No significant differences among Veterans were found between military-specific variables evaluated and sperm quality. In multivariate models, Veterans \u3e /=46 years of age had lower semen volume (beta = -0.10 +/- 0.05; p \u3c 0.05) and lower percent total motile sperm (beta = -18.45 +/- 7.0; p = 0.009) than Veterans 18 to 25 years of age. Black and Hispanic Veterans had lower sperm concentrations as compared to White Veterans (beta = -0.17 +/- 0.07; p = 0.01 and beta = -0.20 +/- 0.06; p \u3c 0.001, respectively). Finally, Veterans diagnosed with post-traumatic stress disorder or major depression had lower total sperm motility (beta = -0.10 +/- 0.03; p = 0.004 and beta = -0.09 +/- 0.04; p \u3c 0.05, respectively). DISCUSSION: Veterans who were older, Hispanic or Black, or diagnosed with post-traumatic stress disorder or major depression were more likely to have lower sperm quality. Longitudinal studies are needed to better characterize the influence of military-specific exposures on semen quality parameters

Are Members of Long-Lived Families Healthier Than Their Equally Long-Lived Peers? Evidence From the Long Life Family Study

BACKGROUND: The Long Life Family Study (LLFS) is a multicenter longitudinal study of exceptional survival among members of long-lived sibships (probands), their offspring, and spouses of either group. For these four roles , we asked: Does membership in a long-lived family protect against disease? METHODS: We used 2008-2010 Beneficiary Annual Summary Files from the Centers for Medicare and Medicaid Services (CMS) to compare prevalences of 17 conditions among 781 LLFS participants in Medicare with those of 3,227 non-LLFS matches from the general Medicare population. Analyses accounted for nesting within LLFS families. RESULTS: Seven conditions were significantly less common among LLFS probands than their matches: Alzheimer\u27s, hip fracture, diabetes, depression, prostate cancer, heart failure, and chronic kidney disease. Four diseases not strongly linked to mortality (arthritis, cataract, osteoporosis, glaucoma) were significantly more common for LLFS probands. Despite fewer people and less disease in those roles, LLFS offspring and LLFS spouses of either generation also had significantly lower risk for Alzheimer\u27s, diabetes, and heart failure. CONCLUSIONS: Common, severe mortality-associated diseases are less prevalent among LLFS probands and their offspring than in the general population of aging Americans. Quality-of-life-limiting diseases such as arthritis and cataract are more prevalent, potentially through more diagnosing of milder forms in otherwise healthy and active individuals. LLFS spouses are also relatively healthy. As the younger cohorts age into Medicare and develop more conditions, it will be important to see whether these tentative findings strengthen

The impact of sleep, stress, and depression on postpartum weight retention: A systematic review

OBJECTIVE: To review the impact of sleep, stress, and/or depression on postpartum weight retention. METHODS: We searched three electronic databases, PubMed, ISI Web of Science, and PsycInfo. Studies were included if they were published between January 1990 and September 2013 in English, measured sleep, stress, and/or depression in the postpartum period, and assessed the association of these factors with postpartum weight retention. Two reviewers reviewed included articles and rated study quality using a modified version of the Downs and Black scale. RESULTS: Thirteen studies met our pre-defined eligibility criteria, reporting on 9 study samples. Two were cross-sectional studies and eleven were longitudinal studies. The study sample size ranged from 74 to 37,127. All four studies examining short sleep duration and postpartum weight retention reported a positive association. The four studies examining postpartum stress and weight retention reported non-significant associations only. Of 7 studies examining postpartum depression and weight retention, 3 reported non-significant associations, and 4 reported positive associations. CONCLUSION: Research investigating the impact of postpartum sleep, stress, depression on weight retention is limited. Future longitudinal studies are needed
