A Regional Analysis of Low Back Pain Treatments in the Military Health System.

STUDY DESIGN: Claims-based analysis of cohorts of TRICARE Prime beneficiaries. OBJECTIVE: To compare rates of utilization of 5 low back pain (LBP) treatments (physical therapy (PT), manual therapy, behavioral therapies, opioid, and benzodiazepine prescription) across catchment areas and assess their association with the resolution of LBP. SUMMARY OF BACKGROUND: Guidelines support focusing on nonpharmacologic management for LBP and reducing opioid use. Little is known about patterns of care for LBP across the Military Health System. PATIENTS AND METHODS: Incident LBP diagnoses were identified data using the International Classification of Diseases ninth revision before October 2015 and 10th revision after October 2015; beneficiaries with "red flag" diagnoses and those stationed overseas, eligible for Medicare, or having other health insurance were excluded. After exclusions, there were 159,027 patients remained in the final analytic cohort across 73 catchment areas. Treatment was defined by catchment-level rates of treatment to avoid confounding by indication at the individual level; the primary outcome was the resolution of LBP defined as an absence of administrative claims for LBP during a 6 to 12-month period after the index diagnosis. RESULTS: Adjusted rates of opioid prescribing across catchment areas ranged from 15% to 28%, physical therapy from 17% to 39%, and manual therapy from 5% to 26%. Multivariate logistic regression models showed a negative and marginally significant association between opioid prescriptions and LBP resolution (odds ratio: 0.97, 95% CI: 0.93-1.00; P = 0.051) but no significant association with physical therapy, manual therapy, benzodiazepine prescription, or behavioral therapies. When the analysis was restricted to the subset of only active-duty beneficiaries, there was a stronger negative association between opioid prescription and LBP resolution (odds ratio: 0.93, 95% CI: 0.89-0.97). CONCLUSIONS: We found substantial variability across catchment areas within TRICARE for the treatment of LBP. Higher rates of opioid prescription were associated with worse outcomes.

Public versus Private Care in the Military Health System: Evidence From Low Back Pain Patients.

INTRODUCTION: There is a longstanding debate about whether health care is more efficiently provided by the public or private sector. The debate is particularly relevant to the Military Health System (MHS), which delivers care through a combination of publicly funded federal facilities and privately contracted providers. This study compares outcomes, treatments, and costs for MHS patients obtaining care for low back pain (LBP) from public versus private providers. MATERIALS AND METHODS: A retrospective cohort study was completed using TRICARE Prime claims data from April 2015 to December 2018. The cohort was identified using International Classification of Diseases Ninth Revision and Tenth Revision diagnostic codes and then followed for 12 months after the index diagnosis to assess treatments, outcomes, and costs. Claims were classified as originating from either public or private providers. The primary outcome measure was resolution of LBP, defined as an absence of LBP diagnoses during the 6-to-12-month window following the index event. Instrumental variable models were used to assess the impact of care setting (i.e., private versus public), conditioning on the covariates. A regional measure of the fraction of private care was used as an instrument. RESULTS: Resolution of LBP was achieved for 79.7% of 144,866 patients in the cohort. No significant association was found between resolution of LBP and fraction of privately provided care. Higher fraction of private care was associated with a greater likelihood of opioid treatments (odds ratio, 1.22; 95% CI, 1.02-1.46) and a lower likelihood of benzodiazepine (odds ratio, 0.56; 95% CI, 0.45-0.70) and physical therapy (odds ratio 0.55; 95% CI, 0.42-0.74) treatments; manual therapy was not significantly associated with the fraction of private care. There was a significant negative association between the fraction of private care and cost (coefficient -0.27; 95% CI, -0.44, -0.10). CONCLUSION: This study found that privately provided care was associated with significantly higher opioid prescribing, less use of benzodiazepines and physical therapy, and lower costs. No systematic differences in outcomes (as measured by resolved cases) were identified. The findings suggest that publicly funded health care within the MHS context can attain quality comparable to privately provided care, although differences in treatment choices and costs point to possibilities for improved care within both systems.

A Methodology for Estimating the Cost of Educating Military Physicians at the Uniformed Services University.

INTRODUCTION: The Department of Defense (DoD) operates a large, multi-channeled physician accession pipeline to maintain a professional workforce of over 10,000 active duty physicians. The Uniformed Services University (USU) operates the nation's only federal medical school providing trained doctors to the Army, Navy, Air Force, and Public Health Service. Although the school serves an essential purpose, policymakers question the cost of operating the University's medical school. One challenge is to develop reproducible and transparent costing methods that can be used to evaluate the University's value and efficiency. METHODS: This work proposes a replicable methodology for estimating the cost per student-year at USU. Using detailed data from USU encompassing facility use, budgeting and expenditures, and faculty and student rosters, we break out and attribute costs to the University's component schools. Using faculty and staff time-use surveys, we further break out education-related personnel costs from other University activities such as research and service. We can then calculate the School of Medicine's annual cost to educate a uniformed physician. RESULTS: In Fiscal Year 2017, it cost the DoD approximately $253,000 per year (more than $1 million dollars total over a 4-year curriculum) to directly educate a physician though the USU School of Medicine. Data from the following Fiscal Year show that education costs grew a modest 2.1% per student-year. CONCLUSIONS: This work provides a foundational framework and approach to estimate the costs of accessioning a physician at USU. This methodology can be replicated for subsequent value analyses of physician accession and retention as budgetary pressures change to match the DoD operating environment. Uniformed Services University's costs should be periodically reassessed against those of alternative accession sources.

Variation in Bariatric Surgery Costs and Complication Rates in the Military Health System.

INTRODUCTION: Within the Military Health System (MHS), facilities have struggled to meet minimum recommended volume thresholds for certain procedures. Understanding variations in complication rates and cost can help policymakers tailor policy to target improvement. Our objective was to quantify the variation in bariatric surgery complication rates and costs across a sample of military hospitals. MATERIALS AND METHODS: We study a retrospective cohort of 38 military surgeons practicing in 21 military treatment facilities from 2007 to 2014 who performed 1,277 bariatric surgeries. Data from the Centralized Credentials and Quality Assurance System, which provides education and training characteristics of physicians, were linked to patient encounter data from the MHS Data Repository. Physicians were included if they performed at least five bariatric surgeries over the study period. Patients were included if they had a diagnosis of obesity (body mass index > 30) and underwent a bariatric weight loss surgery. We calculated and summarized inpatient costs and complication rates across both surgeons and facilities using multivariable mixed-effects linear or logistic models. We used these models to calculate adjusted complication rates and average costs across both providers and hospitals to characterize variation in bariatric outcomes within the MHS. This study was considered exempt by the Uniformed Services University Institutional Review Board. RESULTS: We find evidence of large variations in both complication rates and costs per admission. Overall, we found a 15.5% complication rate across the sample. When comparing averages across facilities, we find large variation in complications (49.4% coefficient of variation [CV]) and procedure costs (25.9% CV). Controlling for patient comorbidities, BMI, and year attenuates much of the variation (12.6% CV complications, 4.4% CV cost), but cannot completely explain differences across facilities. Our model suggests that complications cost 32% more than complication-free surgeries on average suggesting that quality improvement efforts could potentially yield large savings. CONCLUSIONS: We find large variations in complication rates even after controlling for patient health. Furthermore, surgical complications are a significant determinant of cost. Policymakers should target efforts to improve surgical quality across facilities and physicians. Surgical quality improvement initiatives could produce savings to the MHS through reduced complications and improved surgical readiness.

La Palabre: A New Schema for Global Health.

The Ebola virus epidemic in West Africa has led to a paradigm shift in the way the global community responds to outbreaks of disease. This new paradigm places even greater emphasis on collaboration in global health. The palabre, the traditional African practice of mediation and decision-making in the public sphere, offers a schema from which to view current and future global health engagement. This process of dialogue and exchange has many applications to global health exemplified recently by the West African Disaster Preparedness Initiative (WADPI), a follow-on activity to the Operation United Assistance (OUA) Ebola Response effort. WADPI, utilizing the structure of a palabre, seeks to catalyze and synergize constructive collaboration to set a foundation for disaster response in West Africa for years to come.

Experimental approaches for the treatment of malignant gliomas.

Malignant gliomas, which include glioblastomas and anaplastic astrocytomas, are the most common primary tumors of the brain. Over the past 30 years, the standard treatment for these tumors has evolved to include maximal safe surgical resection, radiation therapy and temozolomide chemotherapy. While the median survival of patients with glioblastomas has improved from 6 months to 14.6 months, these tumors continue to be lethal for the vast majority of patients. There has, however, been recent substantial progress in our mechanistic understanding of tumor development and growth. The translation of these genetic, epigenetic and biochemical findings into therapies that have been tested in clinical trials is the subject of this review.
