The Primary Care Analytics Team: Integrating research and clinical care within the Veterans Health Administration Office of Primary Care.

By designing and evaluating health system improvements and providing evidence to clinical decision-makers, embedded researchers are a critical part of a Learning Health System (LHS). In this article, we describe the evolution and mission of the Primary Care Analytics Team (PCAT), an integrated research team within the Veterans Health Administration Office of Primary Care. We discuss challenges and strategies for success in working with clinical operations partners and provide recommendations for other Learning Health Systems units embedded in large integrated health care organizations.

The impact of survey nonresponse on estimates of healthcare employee burnout.

Accurate estimates of burnout prevalence are critical for workforce planning. We assessed survey nonresponse bias and its impact on burnout estimates by linking 27,226 primary care employees to administrative data, categorized by whether they responded to a 2016 workforce survey (19.2% response). We adjusted burnout prevalence by response propensity using mixed-effects logistic regression. Thirty-six percent of respondents screened positive for burnout. There were significant differences between respondents and non-respondents (e.g.,gender, tenure), but no difference between unadjusted (i.e., respondents only) and propensity-adjusted estimates of burnout among the workforce. This provides support that workforce surveys may yield valid burnout estimates despite low response.

Characteristics and Injury Mechanisms of Veteran Primary Care Suicide Decedents with and without Diagnosed Mental Illness.

BACKGROUND: In the United States, suicide rates are increasing among nearly all age groups. Primary care is a critical setting for suicide prevention, where interventions often rely on identifying mental health conditions as indicators of elevated suicide risk. OBJECTIVE: Quantify the proportion of suicide decedents within primary care who had no antecedent mental health or substance use diagnosis. DESIGN: Retrospective cohort study. PARTICIPANTS: Veterans who received Veterans Health Administration (VHA) primary care any time from 2000 to 2014 and died by suicide before 2015 (n = 27,741). MAIN MEASURES: We categorized decedents by whether they had any mental health or substance use diagnosis (yes/no) using ICD-9 codes available from VHA records. We compared sociodemographic, clinical, and suicide mechanism characteristics between groups using chi-square, Student's T, or Wilcoxon tests. RESULTS: Forty-five percent of decedents had no mental health or substance use diagnosis. Decedents without such a diagnosis were older (68 vs. 57 years, p < 0.001), and more likely to be male (98.3% vs. 95.8%, p < 0.001), non-Hispanic White (90.6% vs. 87.9%, p < 0.001), married/partnered (50.4% vs. 36.6%, p < 0.001), and without military service-connected disability benefits (72.6% vs. 56.9%, p < 0.001). They were also more likely to die from firearm injury (78.9% vs. 60.7%, p < 0.001). There were statistically significant differences in physical health between groups, but the magnitudes of those differences were small. Decedents without a mental health or substance use diagnosis had significantly shorter durations of enrollment in VHA healthcare, less healthcare utilization in their last year of life, and had little utilization aside from primary care visits. CONCLUSIONS AND RELEVANCE: From 2000 to 2014, of nearly thirty thousand VHA primary care patients who died by suicide, almost half had no antecedent mental health or substance use diagnosis. Within VHA primary care settings, suicide risk screening for those with and without such a diagnosis is indicated.

Mortality Among Veterans with Major Mental Illnesses Seen in Primary Care: Results of a National Study of Veteran Deaths.

BACKGROUND: Premature mortality observed among the mentally ill is largely attributable to chronic illnesses. Veterans seen within Veterans Affairs (VA) have a higher prevalence of mental illness than the general population but there is limited investigation into the common causes of death of Veterans with mental illnesses. OBJECTIVE: To characterize the life expectancy of mentally ill Veterans seen in VA primary care, and to determine the most death rates of combinations of mental illnesses. DESIGN: Retrospective cohort study of decedents. SETTING/PARTICIPANTS: Veterans seen in VA primary care clinics between 2000 and 2011 were included. Records from the VA Corporate Data Warehouse (CDW) were merged with death information from the National Death Index. MAIN MEASURES: Mental illnesses were determined using ICD9 codes. Direct standardization methods were used to calculate age-adjusted gender and cause-specific death rates per 1000 deaths for patients with and without depression, anxiety, post-traumatic stress disorder (PTSD), substance use disorder (SUD), serious mental illness (SMI), and combinations of those diagnoses. KEY RESULTS: Of the 1,763,982 death records for Veterans with 1 + primary care visit, 556,489 had at least one mental illness. Heart disease and cancer were the two leading causes of death among Veterans with or without a mental illness, accounting for approximately 1 in 4 deaths. Those with SUD (n = 204,950) had the lowest mean age at time of death (64 ± 12 years). Among men, the death rates were as follows: SUD (55.9/1000); anxiety (49.1/1000); depression (45.1/1000); SMI (40.3/1000); and PTSD (26.2/1000). Among women, death rates were as follows: SUD (55.8/1000); anxiety (36.7/1000); depression (45.1/1000); SMI (32.6/1000); and PTSD (23.1/1000 deaths). Compared to men (10.8/1000) and women (8.7/1000) without a mental illness, these rates were multiple-fold higher in men and in women with a mental illness. A greater number of mental illness diagnoses was associated with higher death rates among men and women (p < 0.0001). CONCLUSIONS: Veterans with mental illnesses, particularly those with SUD, and those with multiple diagnoses, had shorter life expectancy than those without a mental illness. Future studies should examine both patient and systemic sources of disparities in providing chronic illness care to Veterans with a mental illness.

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.
