Differences in healthcare costs over 10 years following discharge from military service by weight trajectory.

The prevalence of overweight and obesity among military personnel has increased substantially in the past two decades. Following military discharge many personnel can receive integrated health care from the Veterans Health Administration. Prior research related to the economic impacts of obesity has not examined health care costs following the transition into civilian life following military discharge. To address this evidence gap, this study sought to compare longitudinal costs over 10 years across weight categories among VA enrollees recently discharged from the military.

Comparing internal and external validation in the discovery of qualitative treatment-subgroup effects using two small clinical trials.

In a two-arm randomized trial where both arms receive active treatment (i.e., treatments A and B), often the primary goal is to determine which of the treatments, on average, is more effective. A supplementary objective is to understand possible heterogeneity in the treatment effect by identifying multivariable subgroups of patients for whom A is more effective than B and, conversely, patients for whom B is more effective than A, known as a qualitative interaction. This is the objective of the qualitative interaction trees (QUINT) algorithm developed by Dusseldorp et al (Statistics in Medicine, 2014). We apply QUINT to a small randomized trial comparing facilitated relaxation meditation to facilitated life completion and preparation among patients with life-limiting illness (n = 135). We then conduct an internal validation of the QUINT solution using bootstrap resampling and compare it to an external validation with another, similarly conducted small randomized trial. Internal and external validation showed the apparent range in effect sizes was over-estimated, and subgroups identified were not consistent between the two trials. While the qualitative interaction trees algorithm is a promising area of data-driven multivariable subgroup discovery, our analyses illustrate the importance of validating the solution, particularly for trials with smaller numbers of participants.

Addressing Patient Emotional and Existential Needs During Serious Illness: Results of the Outlook Randomized Controlled Trial.

CONTEXT: Few interventions exist to address patients' existential needs. OBJECTIVES: Determine whether an intervention to address seriously ill patients' existential concerns improves preparation, completion (elements of quality of life [QOL] at end of life), and reduces anxiety and depression. METHODS: A randomized controlled trial comparing outlook intervention, relaxation meditation (RM), and usual care (UC). Measures included primary-a validated measure of QOL at the end of life and secondary-Functional Assessment of Cancer Therapy-General, anxiety (Profile of Mood States), depression (Center for Epidemiological Studies-Depression Scale), and spiritual well-being (Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being). Qualitative interviews assessed outlook intervention acceptability. Enrolled patients were nonhospice eligible veterans with advanced cancer, congestive heart failure, chronic obstructive pulmonary disease, end-stage renal disease, or end-stage liver disease. RESULTS: Patients (n = 221) were randomly assigned 1:1:1 to outlook, RM, and UC. Patients were 96% males, 46% with cancer, 58.4% married, and 43.9% of African American origin. Compared with UC, outlook participants had higher preparation (a validated measure of QOL at the end of life) (mean difference 1.1; 95% CI 0.2, 2.0; P = 0.02) and mean completion (1.6; 95% CI 0.05, 3.1; P = 0.04) at the first but not second postassessment. Compared with RM, outlook participants did not show significant differences over time. Exploratory analyses indicated that in subgroups with cancer and low sense of peace, outlook participants had improved preparation at first and not second postassessment, as compared with UC (mean difference 1.4; 95% CI 0.03, 2.7; P = 0.04) (mean difference = 1.8; 95% CI 0.3, 3.3; P = 0.02), respectively. CONCLUSION: Outlook had an impact on social well-being and preparation compared with UC. The lack of impact on anxiety and depression differs from previous results among hospice patients. Results suggest that outlook is not demonstratively effective in populations not experiencing existential or emotional distress.

Longitudinal adherence to fecal occult blood testing impacts colorectal cancer screening quality.

OBJECTIVES: Existing cross-sectional quality measures for colorectal cancer (CRC) screening do not assess longitudinal adherence and thus may overestimate the quality of care. Our goal was to evaluate the adherence to repeated yearly fecal occult blood tests (FOBTs) in order to better understand the extent to which longitudinal adherence may impact screening quality. METHODS: This was a retrospective cohort analysis of 1,122,645 patients aged 50-75 years seen at any of the 136 Department of Veterans Affairs medical centers across the United States in 2000 and followed through 2005. The primary outcome was receipt of adequate CRC screening as defined by receipt of FOBTs in at least 4 out of 5 years or receipt of any number of FOBTs in addition to at least one colonoscopy, flexible sigmoidoscopy, or double-contrast barium enema. In a predefined subset of patients receiving exclusively FOBT, adherence with repeated testing was determined over the 5-year study period. RESULTS: Only 41.1% of men and 43.6% of women received adequate screening. Of the 384,527 men who received exclusively FOBT, 42.1% received a single FOBT, 26.0% received 2 tests, 17.8% received 3 tests, and only 14.1% were documented to have received at least 4 tests during the study period. Among the 10,469 female veterans receiving FOBT alone, rates were similar with only 13.7% completing at least 4 FOBTs in the 5-year study period. CONCLUSIONS: Adherence to repeated FOBT is low, suggesting that cross-sectional measurements of quality may overestimate the programmatic success of CRC screening.
