Clinical Care Quality Among Veterans Health Administration Patients With Mental Illness Following Medical Home Implementation.

OBJECTIVE: This study sought to compare quality of care following medical home implementation among Veterans Health Administration (VHA) primary care patients with and without mental illness. METHODS: VHA primary care patients seen between April 2010 and March 2013 whose medical records were reviewed by the VHA External Peer Review Program were identified. The proportion of patients meeting quality indicators in each mental illness group (depression, posttraumatic stress disorder, anxiety disorder, substance use disorder, serious mental illness, and any mental illness) was compared with the proportion of patients without mental illness. Sample sizes ranged from 210,864 to 236,421. Differences of 5.0% or greater were deemed clinically important, and higher proportions indicated higher quality of care across 33 clinical indicators. RESULTS: The proportion of veterans meeting clinical quality indicators ranged from 64.7% to 99.6%. Differences of ≥5.0% between veterans with and without mental illness were detected in six of 33 indicators. A greater proportion of veterans with mental illness received influenza immunizations (age 50-64) and had documented left ventricular functioning (among veterans with chronic heart failure) compared with veterans without mental illness. A lower proportion of veterans with substance use disorders or severe mental illness received colorectal cancer screening or met indicators related to recommended medications if diagnosed as having diabetes or ischemic heart disease. CONCLUSIONS: Contrary to earlier reports of lower-quality care, patients with and without mental illness had similar preventive and chronic disease management care quality following medical home implementation.

Comparing Preventable Hospitalizations Among Veterans With and Without Mental Illnesses Before and After Implementation of PACT.

OBJECTIVES: The authors examined whether the rate of preventable hospitalizations among veterans with mental illness changed after implementation of the Department of Veterans Affairs (VA) primary care medical home-Patient Aligned Care Teams (PACT). METHODS: A 12-year retrospective cohort analysis was conducted of data from 9,206,017 veterans seen in 942 VA primary care clinics between October 2003 and March 2015. Preventable hospitalizations were those related to ambulatory care-sensitive conditions (ACSCs), identified with ICD-9 codes. Changes in rates of ACSC-related hospitalizations were compared between patients with and without mental illness in two age groups (<65, ≥65). Patients with mental illness diagnoses were grouped as follows: depression, posttraumatic stress disorder, anxiety, substance use disorder, and serious mental illness. Interrupted time-series analysis was used to model long-term trends and detect deviations after PACT implementation. RESULTS: There was an overall increase in mental illness diagnoses across both age groups. Among older veterans (≥65) with any mental illness, the rate (per 1,000 patients) of ACSC-related hospitalizations was five fewer in the post-PACT period, compared with the pre-PACT period. Among younger veterans (<65), there was a slight increase in ACSC-related hospitalizations in years 3-5 post-PACT if they had any mental illness (.6 per 1,000 patients), depression (.3), anxiety (1.4), or a substance use disorder (.6). CONCLUSIONS: In this retrospective, observational study examining large systemwide changes in clinical practice, mental illness was more likely to be diagnosed after PACT implementation, compared with before, and results suggested a benefit of PACT implementation among older veterans in terms of a reduction in ACSC-related hospitalizations.

The Vietnam Era Twin Registry: a quarter century of progress.

Now celebrating its 26th year of existence, the Vietnam Era Twin Registry continues to be one of the largest national samples of adult twins in the United States. The Registry twin member population is composed of 7,369 US male-male twin pair Veterans (14,738 total individuals) who served on active duty in the military during the Vietnam conflict (1964-1975). The Registry also maintains a register, data repository, and a biospecimen repository. Details on the operations of the Registry are described, as well as an overview of specific studies. Registry maintenance activities are also described, including the updating of contact information and vital status. Future plans include expanding the biospecimen repository and obtaining input from twins about study methods and diseases and conditions they would like to see investigated.
