A prospective cohort study of treatment decision-making for prostate cancer following participation in a multidisciplinary clinic.

Study

Abstract

BACKGROUND: Patients diagnosed with prostate cancer (PCa) are presented with several treatment options of similar efficacy but varying side effects. Understanding how and why patients make their treatment decisions, as well as the effect of treatment choice on long-term outcomes, is critical to ensuring effective, patient-centered care. This study examined treatment decision-making in a racially diverse, equal-access, contemporary cohort of patients with PCa counseled on treatment options at a multidisciplinary clinic. METHODS: A prospective cohort study was initiated at the Walter Reed National Military Medical Center (formerly Walter Reed Army Medical Center) in 2006. Newly diagnosed patients with PCa were enrolled before attending a multidisciplinary clinic. Patients completed surveys preclinic and postclinic to assess treatment preferences, reasons for treatment choice, and decisional regret. RESULTS: As of January 2014, 925 patients with PCa enrolled in this study. Surgery (54%), external radiation (20%), and active surveillance (12%) were the most common primary treatments for patients with low- and intermediate-risk PCa, whereas patients with high-risk PCa chose surgery (34%) or external radiation with neoadjuvant hormones (57%). Treatment choice differed by age at diagnosis, race, comorbidity status, and calendar year in both univariable and multivariable analyses. Patients preferred to play an active role in the decision-making process and cited doctors at the clinic as the most helpful source of treatment-related information. Almost all patients reported satisfaction with their decision. CONCLUSIONS: This is one of the first prospective cohort studies to examine treatment decision-making in an equal-access, multidisciplinary clinic setting. Studies of this cohort would aid in understanding and improving the PCa decision-making process.

Anger and Posttraumatic Stress Disorder Symptom Severity in a Trauma-Exposed Military Population: Differences by Trauma Context and Gender.

Study

Abstract

Studies have found a stronger association between anger and posttraumatic stress disorder (PTSD) severity in military populations than in nonmilitary populations. Two hypotheses have been proposed to explain this difference: Military populations are more prone to anger than nonmilitary populations, and traumas experienced on deployment create more anger than nondeployment traumas. To examine these hypotheses, we evaluated the association between anger and PTSD severity among never-deployed military service members with nondeployment traumas (n = 226) and deployed service members with deployment traumas (n = 594) using linear regression. We further examined these associations stratified by gender. Bivariate associations between anger and PTSD severity were similar for nondeployment and deployment events; however, gender modified this association. For men, the association for deployment events was stronger than for nondeployment events (β = .18, r = .53 vs. β = .16, r = .37, respectively), whereas the reverse was true for women (deployment: β = .20, r = .42 vs. nondeployment: β = .25, r = .65). Among men, findings supported the hypothesis that deployment traumas produce stronger associations between PTSD and anger and are inconsistent with hypothesized population differences. In women, however, there was not a clear fit with either hypothesis.

A Prognostic Model to Predict Mortality among Non-Small-Cell Lung Cancer Patients in the U.S. Military Health System.

Study

Abstract

INTRODUCTION: Accurate prognosis assessment after non-small-cell lung cancer (NSCLC) diagnosis is an essential step for making effective clinical decisions. This study is aimed to develop a prediction model with routinely available variables to assess prognosis in patients with NSCLC in the U.S. Military Health System. METHODS: We used the linked database from the Department of Defense's Central Cancer Registry and the Military Health System Data Repository. The data set was randomly and equally split into a training set to guide model development and a testing set to validate the model prediction. Stepwise Cox regression was used to identify predictors of survival. Model performance was assessed by calculating area under the receiver operating curves and construction of calibration plots. A simple risk scoring system was developed to aid quick risk score calculation and risk estimation for NSCLC clinical management. RESULTS: The study subjects were 5054 patients diagnosed with NSCLC between 1998 and 2007. Age, sex, tobacco use, tumor stage, histology, surgery, chemotherapy, peripheral vascular disease, cerebrovascular disease, and diabetes mellitus were identified as significant predictors of survival. Calibration showed high agreement between predicted and observed event rates. The area under the receiver operating curves reached 0.841, 0.849, 0.848, and 0.838 during 1, 2, 3, and 5 years, respectively. CONCLUSIONS: This is the first NSCLC prognosis model for quick risk assessment within the Military Health System. After external validation, the model can be translated into clinical use both as a web-based tool and through mobile applications easily accessible to physicians, patients, and researchers.

Unintended pregnancy among active-duty women in the United States military, 2011.

Study

Abstract

OBJECTIVES: Unintended pregnancy among active-duty women in the United States military, 2011. STUDY DESIGN: Cross-sectional data came from the 2011 Department of Defense Health Related Behaviors Survey of Active Duty Military Personnel; 9038 women provided data on unintended pregnancy. Unintended pregnancy rates were calculated for all women and by available background characteristics, including military branch, marital status (married versus unmarried), pay grade (enlisted versus officer) and deployment in the previous 12months. Multivariable logistic regression testing for associations between unintended pregnancy and subgroups was also performed. RESULTS: The unintended pregnancy rate was 72/1000 women. Married women (odds ratio (OR) 1.30, 95% confidence interval (CI) 1.11-1.54) and enlisted women (OR 2.71, 95% CI 1.99-3.69) had higher odds of reporting unintended pregnancy compared to their counterparts, as did women in the Navy (OR 1.51, 95% CI 1.19-1.91) and Marine Corps (OR 2.38, 95% CI 1.92-2.95) compared to women in the Air Force. Unintended pregnancy rates did not differ between women who were deployed in the previous 12months and nondeployed women. Additionally, 10% of women who were deployed for 11-12months in 2011 reported an unintended pregnancy in the previous year, suggesting that their pregnancies occurred during deployment. CONCLUSION: Unintended pregnancy is higher in the military, including during deployment, compared to the general U.S. population (52/1000 women). All branches need to address the issue in a comprehensive manner including evidence-based provision of contraception and education among servicemembers. IMPLICATIONS: Unintended pregnancy is high in the military, including during deployment; further efforts to improve evidence-based provision of contraception and education are needed.

Retrospective Analysis of Long-Term Outcomes After Combat Injury: A Hidden Cost of War.

Study

Abstract

BACKGROUND: During the conflicts in Iraq and Afghanistan, 52 087 service members have been wounded in combat. The long-term sequelae of these injuries have not been carefully examined. We sought to determine the relation between markers of injury severity and the subsequent development of hypertension, coronary artery disease, diabetes mellitus, and chronic kidney disease. METHODS AND RESULTS: Retrospective cohort study of critically injured US military personnel wounded in Iraq or Afghanistan from February 1, 2002 to February 1, 2011. Patients were then followed until January 18, 2013. Chronic disease outcomes were assessed by International Classification of Diseases, 9th edition codes and causes of death were confirmed by autopsy. From 6011 admissions, records were excluded because of missing data or if they were for an individual's second admission. Patients with a disease diagnosis of interest before the injury date were also excluded, yielding a cohort of 3846 subjects for analysis. After adjustment for other factors, each 5-point increment in the injury severity score was associated with a 6%, 13%, 13%, and 15% increase in incidence rates of hypertension, coronary artery disease, diabetes mellitus, and chronic kidney disease, respectively. Acute kidney injury was associated with a 66% increase in rates of hypertension and nearly 5-fold increase in rates of chronic kidney disease. CONCLUSIONS: In Iraq and Afghanistan veterans, the severity of combat injury was associated with the subsequent development of hypertension, coronary artery disease, diabetes mellitus, and chronic kidney disease.

Vaccine-associated reduction in symptom severity among patients with influenza A/H3N2 disease.

Study

Abstract

BACKGROUND: The moderate level of protection conferred by influenza vaccines is well-known, but the vaccine's ability to attenuate symptom severity among vaccinated individuals (i.e., vaccine failures) has not been established. METHODS: We enrolled otherwise healthy adults who presented with influenza-like illness (ILI) at five US military hospitals between 2009 and 2014. Influenza was diagnosed and subtyped by PCR. Individual and composite severity scores were compared between those who had vs. had not received the seasonal influenza vaccine >14 days prior to enrollment. RESULTS: A total of 155 cases of influenza (A/H1N1, n=69; A/H3N2, n=66; A/untyped, n=3; B, n=17) were identified, of whom 111 (72%; A/H1N1, n=44; A/H3N2, n=52; A/untyped, n=3; B, n=12) had been vaccinated. Women were significantly less likely to be vaccinated than men (49% vs. 89%; p<0.01). In multivariate analysis, vaccinated individuals were significantly less likely to report a fever >101°F (OR 0.24; 95% CI [0.10, 0.62]) and more likely to report myalgias (OR 3.31; 95% CI [1.22, 8.97]) than vaccinated individuals. Among patients with A/H3N2 infection, upper respiratory and total symptom severity scores were significantly lower for vaccinated patients during the first 2 days of illness, and differences in total symptom severity persisted over 7 days (p<0.05 for all comparisons). Differences across additional symptom categories (lower respiratory and systemic) were also observed throughout 7 days of illness in bivariate analyses. Differences in symptom severity were not observed between vaccinated and unvaccinated participants with A/H1N1 infection. CONCLUSIONS: Among patients with A/H3N2 infection, receipt of seasonal influenza vaccine was associated with reduced symptom severity. Patient-centered discussion about the benefits of influenza vaccination should be expanded to include the possibility that the vaccine could attenuate symptoms.

Risk factors for severe outcomes among members of the United States military hospitalized with pneumonia and influenza, 2000-2012.

Study

Abstract

BACKGROUND: The progression from hospitalization for a respiratory infection to requiring substantial supportive therapy is a key stage of the influenza severity pyramid. Respiratory infections are responsible for 300,000-400,000 medical encounters each year among US military personnel, some of which progress to severe acute respiratory infections. METHODS: We obtained data on 11,086 hospitalizations for pneumonia and influenza (P&I) among non-recruit US military service members during the period of 1 January 2000 through 31 December 2012. From these, we identified 512 P&I hospitalizations that progressed to severe episodes using standard case definitions. We evaluated the effect of demographic and occupational characteristics, co-morbid conditions, and history of influenza vaccination on the risk of a hospitalized P&I case becoming a severe case. We also evaluated the risk of a severe outcome and the length of time since influenza vaccination (within 180, 60, and 30 days). RESULTS: The median age of subjects at the time of the P&I episode was 32 years (range, 28-40) and subjects were predominantly male (89.5%). In a univariate analysis, demographic risk factors for a severe episode included service in the US Air Force (RR=1.6 relative to US Army, 95%CI 1.3-2.1), US Coast Guard (RR=2.1, 1.2-3.7) or US Navy (RR=1.4, 1.1-1.8). Being born in the US and recent influenza vaccination (within 180 days of episode) were protective against developing severe disease. Among co-morbid conditions, univariate risk factors for severe disease included chronic renal or liver disease (RR=4.98, 95%CI 4.1-6.1), diseases of the circulatory system (RR=3.1, 95%CI 2.6-3.7), diabetes mellitus (RR=2.3, 95%CI 1.5-3.6), obesity (RR=1.6, 95%CI 1.2-2.1), cancer (RR=1.6, 95%CI 1.3-2.0), and chronic obstructive pulmonary disease (RR=1.4, 95%CI 1.1-1.7). Although many of the risk factors found to be significant in univariate analysis were no longer significant under a multivariate analysis, receipt of any influenza vaccine within 180 days of episode remained protective (RR=0.81, 95%CI 0.67-0.99), while serving in the US Coast Guard (RR=1.9, 95%CI 1.1-3.4) or US Air Force (RR=1. 5, 95%CI 1.2-2.0), presence of renal or liver disease (RR=3.6, 95%CI 2.9-4.6), and diseases of the circulatory system (RR=2.2, 95%CI 1.8-2.8), remained significantly associated with a higher risk of developing severe disease. CONCLUSIONS: In a large cohort, after adjusting for many possible risk factors, influenza vaccination was protective against severe episodes among P&I hospitalizations. The service-specific (US Coast Guard or US Air Force) increased risk may represent some differences in data (e.g., coding or reporting practices) as opposed to genuine differences in physiological outcome. Our findings suggest that renal and liver disease as well as diseases of the circulatory system may contribute to influenza severity in this population independently of age and other potential comorbidities. These findings provide additional evidence for the prioritization of specific risk groups within the US military for influenza vaccination.

Treatment of active duty military with PTSD in primary care: A follow-up report.

Study

Abstract

First-line trauma-focused therapies offered in specialty mental health clinics do not reach many veterans and active duty service members with posttraumatic stress disorder (PTSD). Primary care is an ideal environment to expand access to mental health care. Several promising clinical case series reports of brief PTSD therapies adapted for primary care have shown positive results, but the long-term effectiveness with military members is unknown. The purpose of this study was to determine the long-term outcome of an open trial of a brief cognitive-behavioral primary care-delivered protocol developed specifically for deployment-related PTSD in a sample of 24 active duty military (15 men, 9 women). Measures of PTSD symptom severity showed statistically and clinically significant reductions from baseline to posttreatment that were maintained at the 6-month and 1-year follow-up assessments. Similar reductions were maintained in depressive symptoms and ratings of global mental health functioning.

Deployment, combat, and risk of multiple physical symptoms in the US military: A prospective cohort study.

Study

Abstract

PURPOSE: Multiple physical symptoms (MPS) have historically been observed after deployment to a combat zone and are often disabling in nature. This study examined longitudinal trends in MPS status and its relationship to deployment in U.S. military service members. METHODS: Using longitudinal data from panel 1 participants in the Millennium Cohort Study (n = 76,924), MPS status was assessed at three time points (2001-2008) using the 15-item Patient Health Questionnaire. Probability of reporting MPS was analyzed using mixed-effects multinomial logit regression, with time and deployment experience as main explanatory variables. RESULTS: After adjustment for demographic, military, and health characteristics, service members who deployed with combat were significantly more likely to report MPS at each time point compared with those not deployed (odds ratio [OR] and 95% confidence interval [CI] for wave 1 = 1.49 [1.47-1.52], wave 2 = 1.73 [1.69-1.78], wave 3 = 2.08 [2.03-2.12]), and those who deployed without combat (OR and CI for wave 1 = 2.66 [2.59-2.74], wave 2 = 1.81 [1.75-1.87]; wave 3 = 1.68 [1.63-1.74]). CONCLUSIONS: Longitudinal trends indicate that the probability of reporting MPS has increased consistently over time only for those deployed, regardless of combat experience.

Postdischarge Cause-of-Death Analysis of Combat-Related Burn Patients.

Study

Abstract

Combat operations in Iraq and Afghanistan have resulted in up to 8.8% of combat-related casualties suffering burns. From World War I through Desert Storm, burns have been associated with approximately 4% of the combat-related deaths. Experiencing a blast injury and exposure to killing and death while deployed has been shown to increase suicide risk. Although several studies of military populations have investigated risk factors for death among burn patients during the acute phase, no studies have reported mortality rates, cause-of-death, or the prevalence of suicide after hospital discharge. This study examined the case fatality rate, causes of death, and the prevalence of suicide among 830 combat burn patients discharged from the sole burn center in the U.S. Department of Defense, between March 7, 2003 and March 6, 2013. Cause-of-death was determined through the Armed Forces Medical Examiner's Office and the Office of the Secretary of Defense's National Death Index. A total of 11 deaths occurred among the 830 burn survivors, for an overall case fatality rate of 1.3%. Of the 11 who died, five deaths were related to accidental poisoning by exposure to drugs; three were related to operations of war (two after returning to the war zone), and the remaining three died from other accidental causes (one explosion and two vehicle crashes). There was no indication of suicide or suspicion of suicide as a cause-of-death for the former patients included in this study, suggesting that combat burn injury did not appear to increase the risk of death by suicide in our study population. Further research is needed to understand the factors that contribute to the apparent resilience of combat burn survivors.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

Prescription Stimulants and PTSD Among U. S. Military Service Members.

Study

Abstract

Posttraumatic stress disorder (PTSD) is a prevalent condition among military service members and civilians who have experienced traumatic events. Stimulant use has been postulated to increase the risk of incident PTSD; however, research in this area is lacking. In this study, the association between receipt of prescription stimulants and PTSD was examined in a secondary analysis among active duty U.S. military members (n = 25,971), participating in the Millennium Cohort Study, who completed a baseline (2001-2003) and two follow-up surveys (between 2004-2008). Prescription stimulant data were obtained from the military Pharmacy Data Transaction Service. PTSD was assessed using the PTSD Checklist-Civilian Version and incident PTSD was defined as meeting the criteria at follow-up among those who did not have a history of PTSD at baseline. Overall, 1,215 (4.7%) persons developed new-onset PTSD during follow-up. Receipt of prescription stimulants were significantly associated with incident PTSD, hazard ratio = 5.09, 95% confidence interval [3.05, 8.50], after adjusting for sociodemographic factors, military characteristics, attention-deficit/hyperactivity disorder, baseline mental and physical health status, deployment experiences, and physical/sexual trauma. Findings suggested that prescription stimulants are associated with incident PTSD among military personnel; these data may inform the underlying pathogenesis of and preventive strategies for PTSD.

Prevalence of mental health conditions after military blast exposure, their co-occurrence, and their relation to mild traumatic brain injury.

Study

Abstract

PRIMARY OBJECTIVES: To measure common psychiatric conditions after military deployment with blast exposure and test relationships to post-concussion syndrome (PCS) symptoms and mild traumatic brain injury (mTBI) history. RESEARCH DESIGN: Cross-sectional. METHODS AND PROCEDURES: Service members or Veterans (n = 107) within 2 years of blast exposure underwent structured interviews for mTBI, post-traumatic stress disorder (PTSD) and multiple mood and anxiety diagnoses. MAIN OUTCOMES AND RESULTS: MTBI history and active PTSD were both common, additionally 61% had at least one post-deployment mood or anxiety disorder episode. Psychiatric diagnoses had a high degree of comorbidity. Most dramatically, depression was 43-times (95% CI = 11-165) more likely if an individual had PTSD. PCS symptoms were greater in those with post-deployment PTSD or mood diagnosis. However, neither mTBI nor blast exposure history had an effect on the odds of having PTSD, mood or anxiety condition. CONCLUSIONS: These findings support that psychiatric conditions beyond PTSD are common after military combat deployment with blast exposure. They also highlight the non-specificity of post-concussion type symptoms. While some researchers have implicated mTBI history as a contributor to post-deployment mental health conditions, no clear association was found. This may partly be due to the more rigorous method of retrospective mTBI diagnosis determination.

Military-to-civilian translation of battlefield innovations in operative trauma care.

Study

Abstract

BACKGROUND: Historic improvements in operative trauma care have been driven by war. It is unknown whether recent battlefield innovations stemming from conflicts in Iraq/Afghanistan will follow a similar trend. The objective of this study was to survey trauma medical directors (TMDs) at level 1-3 trauma centers across the United States and gauge the extent to which battlefield innovations have shaped civilian practice in 4 key domains of trauma care. METHODS: Domains were determined by the use of a modified Delphi method based on multiple consultations with an expert physician/surgeon panel: (1) damage control resuscitation (DCR), (2) tourniquet use, (3) use of hemostatic agents, and (4) prehospital interventions, including intraosseous catheter access and needle thoracostomy. A corresponding 47-item electronic anonymous survey was developed/pilot tested before dissemination to all identifiable TMD at level 1-3 trauma centers across the US. RESULTS: A total of 245 TMDs, representing nearly 40% of trauma centers in the United States, completed and returned the survey. More than half (n = 127; 51.8%) were verified by the American College of Surgeons. TMDs reported high civilian use of DCR: 95.1% of trauma centers had implemented massive transfusion protocols and the majority (67.7%) tended toward 1:1:1 packed red blood cell/fresh-frozen plasma/platelets ratios. For the other 3, mixed adoption corresponded to expressed concerns regarding the extent of concomitant civilian research to support military research and experience. In centers in which policies reflecting battlefield innovations were in use, previous military experience frequently was acknowledged. CONCLUSION: This national survey of TMDs suggests that military data supporting DCR has altered civilian practice. Perceived relevance in other domains was less clear. Civilian academic efforts are needed to further research and enhance understandings that foster improved trauma surgeon awareness of military-to-civilian translation.

Challenges in Obtaining Estimates of the Risk of Tuberculosis Infection During Overseas Deployment.

Study

Abstract

Estimates of the risk of tuberculosis (TB) infection resulting from overseas deployment among U.S. military service members have varied widely, and have been plagued by methodological problems. The purpose of this study was to estimate the incidence of TB infection in the U.S. military resulting from deployment. Three populations were examined: 1) a unit of 2,228 soldiers redeploying from Iraq in 2008, 2) a cohort of 1,978 soldiers followed up over 5 years after basic training at Fort Jackson in 2009, and 3) 6,062 participants in the 2011-2012 National Health and Nutrition Examination Survey (NHANES). The risk of TB infection in the deployed population was low-0.6% (95% confidence interval [CI]: 0.1-2.3%)-and was similar to the non-deployed population. The prevalence of latent TB infection (LTBI) in the U.S. population was not significantly different among deployed and non-deployed veterans and those with no military service. The limitations of these retrospective studies highlight the challenge in obtaining valid estimates of risk using retrospective data and the need for a more definitive study. Similar to civilian long-term travelers, risks for TB infection during deployment are focal in nature, and testing should be targeted to only those at increased risk.

Follow-up analysis of the incidence of acute respiratory infections among enlisted service members during their first year of military service before and after the 2011 resumption of adenovirus vaccination of basic trainees.

Study

Abstract

This analysis estimated the incidence rates of acute respiratory infections (ARIs) during the first year of military service for service members in 16 cohorts (designated 1999 through 2014) based on the years in which they began their service. That first year of service was divided into two separate follow-up periods: the first 3 months of service (corresponding to the period of initial entry training) and the next 9 months of service (months 4-12). The surveillance period covered service members whose first years of service were before and after the 2011 resumption of the administration of adenovirus vaccines, types 4 and 7, to enlisted trainees at the beginning of their initial training periods. In general, the findings were that incidence rates of ARIs were relatively high for the cohorts who did not receive the vaccines, and that the rates were dramatically lower in the cohorts (2012-2014) who did receive the vaccines. These observations pertained to both the first 3 months of service and the next 9 months of service. Possible interpretations of these findings and the limitations of the study methods are discussed.
