Identifying Patterns of Primary Care In-Person and Telemedicine Use in the Veterans Health Administration: A Latent Class Analysis.

BACKGROUND: The Veterans Health Administration increased synchronous telemedicine (video and telephone visits) in primary care in response to the COVID-19 pandemic. OBJECTIVE: Our objective was to determine veteran use patterns of in-person and telemedicine primary care when all modalities were available. DESIGN: A retrospective cohort analysis. We performed a latent class analysis of primary care visits over a 1-year period to identify veteran subgroup (i.e., class) membership based on amount of primary care use and modality used. Then, we used multinomial logistic regression with a categorical outcome to identify patient characteristics associated with class identification. PARTICIPANTS: A random national sample consisting of 564,580 primary care empaneled veterans in June 2021. MAIN MEASURES: Latent class membership. KEY RESULTS: We identified three latent classes: those with few primary care visits that were predominantly telephone-based (45%), intermediate number of visits of all modalities (50%), and many visits of all modalities (5%). In an adjusted model, characteristics associated with the "few" visits class, compared to the intermediate class, were older age, male sex, White race, further driving distance to primary care, higher Gagne, optimal internet speed, and unmarried status (OR 1.002, 1.52, 1.13, 1.004, 1.04, 1.05, 1.06, respectively; p < .05). Characteristics associated with membership in the "many" visits class, compared to the intermediate class, were Hispanic race, higher JEN Frailty Index and Gagne (OR 1.12, 1.11, 1.02, respectively; p < .05), and higher comorbidity by Care Assessment Need score quartile (Q2 1.73, Q3 2.80, Q4 4.12; p < 0.05). CONCLUSIONS: Veterans accessing primary care in-person or via telemedicine do so primarily in three ways: (1) few visits, predominantly telephone; (2) intermediate visits, all modalities, (3) many visits, all modalities. We found no groups of veterans receiving a majority of primary care through video.

Automated Reminders Enhance Mailed Fecal Immunochemical Test Completion Among Veterans: a Randomized Controlled Trial.

BACKGROUND: The Veterans Affairs (VHA) is working to establish a population-based colorectal cancer screening program for average-risk patients using mailed fecal immunochemical testing (FIT). However, low response rates to mailed FIT may hinder success. Key features of mailed FIT programs, including the use of reminders, differ among various national programs, with limited evidence among veterans. OBJECTIVE: We sought to test whether using reminders, either via telephone call or text message, was effective in improving mailed FIT response rates. DESIGN: We conducted a prospective, randomized quality improvement trial ( ClinicalTrials.gov NCT05012007). Veterans who had not returned a FIT within 2 weeks of receiving the kit were randomized to one of three groups: (1) control (no reminder); (2) an automated telephone call reminder; or (3) an automated text message reminder. PARTICIPANTS: A total of 2658 veterans enrolled at VA Puget Sound Health Care System who were aged 45-75 and had an average risk of colorectal cancer. INTERVENTIONS: A single automated telephone call or text message reminder prompting veterans to return the FIT kit. MAIN MEASURES: Our primary outcome was FIT return at 90 days and our secondary outcome was FIT return at 180 days. KEY RESULTS: Participant average age was 62 years, 88% were men, and 66% White. At 90 days, both the phone and text reminder interventions had higher FIT return rates compared to control (intention-to-treat results (ITT): control 28%, phone 39%, text 38%; p<0.001). At 180 days, FIT kit return remained higher in the reminder interventions (ITT: control 32%, phone 42%, text 40%; p<0.001). CONCLUSIONS: Automated reminders increased colorectal cancer screening completion among average-risk veterans. An automated phone call or text message was equally effective. VHA facilities seeking to implement a mailed FIT program should consider using phone or text reminders, depending on available resources.

A Postcard Primer Prior to Mailed Fecal Immunochemical Test Among Veterans: a Randomized Controlled Trial.

BACKGROUND: Mailed fecal immunochemical testing (FIT) programs are increasingly utilized for population-based colorectal cancer (CRC) screening. Advanced notifications (primers) are one behavioral designed feature of many mailed FIT programs, but few have tested this feature among Veterans. OBJECTIVE: To determine if an advanced notification, a primer postcard, increases completion of FIT among Veterans. DESIGN: This is a prospective, randomized quality improvement trial to evaluate a postcard primer prior to a mailed FIT versus mailed FIT alone. PARTICIPANTS: A total of 2404 Veterans enrolled for care at a large VA site that were due for average-risk CRC screening. INTERVENTION: A written postcard sent 2 weeks in advance of a mailed FIT kit that contained information on CRC screening and completing a FIT. MAIN MEASURES: Our primary outcome was FIT completion at 90 days, and our secondary outcome was FIT completion at 180 days. KEY RESULTS: Overall, unadjusted mailed FIT return rates were similar among control vs. primer arms at 90 days (27% vs. 29%, p = 0.11). Our adjusted analysis found a primer postcard did not increase FIT completion compared to mailed FIT alone (OR 1.14 (0.94, 1.37)). CONCLUSIONS: Though primers are often a standard part of mailed FIT programs, we did not find an increase in FIT completion with mailed postcard primers among Veterans. Given the overall low mailed FIT return rates, testing different ways to improve return rates is essential to improving CRC screening.

Home Telehealth in the Veterans Health Administration: Trends and Correlates of Length of Enrollment from 2010 to 2017.

BACKGROUND: Home telehealth (HT) programs enable communication and remote monitoring of patient health data between clinician visits, with the goal of improving chronic disease self-management and outcomes. The Veterans Health Administration (VHA) established one of the earliest HT programs in the country in 2003; however, little is known about how these services have been utilized and expanded over the last decade. OBJECTIVE: To describe trends in use of VHA's HT program from 2010 through 2017 and correlates of length of enrollment in HT services. DESIGN: Retrospective observational cohort study. PARTICIPANTS: Patients enrolled in HT between January 1, 2010 and December 31, 2017. MAIN MEASURES: We described the number and characteristics of patients enrolled in HT, including the chronic conditions managed. We also identified length of HT enrollment and examined patient and facility characteristics associated with longer enrollment. KEY RESULTS: The total number of patients enrolled in HT was 402,263. At time of enrollment, half were >65 years old, 91% were male, and 59.3% lived in urban residences. The most common conditions addressed by HT were hypertension (28.8%), obesity (23.9%), and diabetes (17.0%). The median time to disenrollment in HT was 261 days (8.6 months) but varied by chronic condition. In a multivariable Cox proportional hazards model, covariates associated with higher likelihood of staying enrolled were older age, male gender, non-Hispanic Black race/ethnicity, lower neighborhood socioeconomic status, living in a more rural setting, and a greater burden of comorbidities per the Gagne index. CONCLUSIONS: Across 8 years, over 400,000 veterans engaged in HT services for chronic disease management and over half remained in the program for longer than 8 months. Our work provides a real-world evaluation of HT service expansion in the VHA. Additional studies are necessary to identify optimal enrollment duration and patients most likely to benefit from HT services.

Events Associated With Changes in Reliance on the Veterans Health Administration Among Medicare-eligible Veterans.

OBJECTIVES: We can learn something about how Veterans value the Veterans Health Administration (VHA) versus community providers by observing Veterans' choices between VHA and Medicare providers after they turn 65. For a cohort of Veterans who were newly age-eligible for Medicare, we estimated the change in VHA reliance (VHA outpatient visits divided by total VHA and Medicare visits) associated with specific events: receiving a life-threatening diagnosis, having a Medicare-paid hospitalization, or moving further from the VHA. RESEARCH DESIGN: A longitudinal cohort study of VHA and Medicare administrative data. SUBJECTS: A total of 5932 VHA users who completed a health survey in 1999 and became age-eligible for Medicare from 1998 to 2000 were followed through 2016. PRINCIPAL FINDINGS: More Veterans chose to rely on the VHA than Medicare (64% vs. 36.%). For a VHA-reliant Veteran, a Medicare-paid hospital stay was associated with a decrease of 7.8 percentage points (pps) (P<0.001) in VHA reliance in the subsequent 12 months, but by 36 months reliance increased to near prehospitalization levels (-1.5 pps; P=0.138). Moving further from the VHA, or receiving a diagnosis of cancer, heart failure, or renal failure had no significant association with subsequent VHA reliance; however, a diagnosis of dementia was associated with a decrease in VHA reliance (-8.6 pps; P=0.026). CONCLUSIONS: A significant majority of newly Medicare-eligible VHA users voted with their feet in favor of sustaining the VHA as a provider of comprehensive medical care for Veterans. These VHA-reliant Veterans maintained their reliance even after receiving a life-threatening diagnosis, and after experiencing Medicare-provided hospital care.

Components of the Patient-Centered Medical Home Associated with Perceived Access to Primary Care.

BACKGROUND: Following implementation of the patient-centered medical home (PCMH) within the Department of Veterans Affairs (VA), access to primary care improved. However, understanding of how this occurred is lacking. OBJECTIVE: To examine the association between organizational aspects of the PCMH model and access-related initiatives with patient perception of access to urgent, same-day, and routine care within the VA. DESIGN: Cross-sectional PARTICIPANTS: Veterans who responded to the annual Survey of Healthcare Experiences of Patients in 2016 (N = 241,122 patients) and primary staff who responded to VA National Primary Care Provider and Staff Survey (N = 4815 staff). MAIN MEASURES: Three outcomes of perception of access: percentage of patients responding in the highest category for same-day care (waiting ≤ 1 day), urgent care (always receiving care when needed), and routine care (always receiving checkups when desired). Predictors were staff-level report of access-related initiatives and organizational factors in the clinic. We used generalized estimating equations to model associations, adjusting for characteristics of patients and their respective clinics. KEY RESULTS: Access was significantly better in clinics where staff reviewed performance reports (+ 0.9% in the highest perception of access for urgent care, P < 0.01; + 1.2% for routine care, P < 0.001), leadership was supportive of the PCMH (+ 1.6% for urgent care, P < 0.01), and initiatives to improve access included open access (+ 0.8% to + 1.7% across all outcomes, P < 0.01) and telehealth visits (+ 1.2% to + 1.4%, P < 0.001). Perceived access was worse in clinics with moderate staff burnout (- 1.1% to - 1.4%, P < 0.001), primary care provider turnover during the past year (- 1.0% to - 1.6%, P < 0.001), or medical support assistant turnover in the past year (- 0.9% to - 1.4%, P < 0.001). CONCLUSIONS: Perception of access was strongly associated with identifiable organizational factors and access-related initiatives within VA primary care clinics that could be adopted by other health systems.

Evaluating equity in a national virtual care management intervention: Delivery and outcomes by race/ethnicity among Veterans with hypertension and diabetes.

OBJECTIVE: To evaluate whether the Preventive Health Inventory (PHI)-a virtual care management intervention addressing hypertension and diabetes management implemented nationally in the Veterans Health Administration (VHA)-was delivered equitably among racial/ethnic groups and if existing inequities in hypertension and diabetes outcomes changed following PHI receipt. DATA SOURCES AND STUDY SETTING: We used data from the VHA Corporate Data Warehouse among Veterans enrolled in primary care nationally from February 28, 2021 to March 31, 2022. STUDY DESIGN: We used logistic regression to evaluate PHI receipt and hypertension and diabetes outcomes after PHI implementation among Veterans with hypertension and/or diabetes. We conducted unadjusted analyses and analyses adjusting for clinic fixed effects using dummy variables. DATA COLLECTION/EXTRACTION METHODS: We identified Veterans engaged in primary care with documented race/ethnicity and hypertension and/or diabetes diagnoses in all months during the study period. PRINCIPLE FINDINGS: Prior to PHI, Non-Hispanic Black (NHB) (42.2%) and Hispanic (39.5%) Veterans were less likely to have controlled hypertension vs. Non-Hispanic White (NHW) Veterans (47.5%); NHB Veterans (32.9%) were more likely to have uncontrolled diabetes vs. NHW Veterans (25.1%). Among 1,805,658 Veterans, 5.7% NHW (N = 68,744), 5.6% NHB (N = 22,580), 10.2% Hispanic (N = 13,313), 6.2% Asian/Pacific Islander/Native Hawaiian (N = 1868), 5.1% American Indian/Native Alaskan (N = 744), and 5.6% multiple races or other race (N = 1647) Veterans received PHI. We found no significant racial inequities in PHI receipt in unadjusted and adjusted models. Hypertension and diabetes measures improved more in the intervention group compared with the group who did not receive the intervention. There were no new or worsened inequities after PHI, and in pre-/post-intervention analysis, among NHB Veterans, the inequity in uncontrolled diabetes improved by 1.9 percentage points (95% CI 0.2, 3.6). CONCLUSIONS: Our findings suggest the PHI intervention was equitably deployed across race/ethnicity groups without significantly impacting most existing inequities in diabetes and hypertension.

Automated Opt-Out vs Opt-In Patient Outreach Strategies for Breast Cancer Screening: A Randomized Clinical Trial.

Importance: Optimal strategies for population-based outreach for breast cancer screening remain unknown. Objective: To evaluate the effect on breast cancer screening of an opt-out automatic mammography referral strategy compared with an opt-in automated telephone message strategy. Design, Setting, and Participants: This pragmatic randomized clinical trial was conducted from April 2022 to January 2023 at a single Veterans Affairs (VA) medical center. Participants were female veterans aged 45 to 75 years who were eligible for breast cancer screening and enrolled in VA primary care. Intervention: Veterans were randomized 1:1 to receive either an automatic mammography referral (opt-out arm) or an automated telephone call with an option for mammography referral (opt-in arm). Main Outcomes and Measures: The primary outcome was completed mammography 100 days after outreach. Secondary outcomes were scheduled or completed mammography by 100 days after outreach and referrals canceled if mammography was not scheduled within 90 days. Both intention-to-treat analyses and a restricted analysis were conducted. The restricted analysis excluded veterans who were unable to be reached by telephone (eg, a nonworking number) or who were found to be ineligible after randomization (eg, medical record documentation of recent mammography). Results: Of 883 veterans due for mammography (mean [SD] age, 59.13 [8.24] years; 656 [74.3%] had received prior mammography), 442 were randomized to the opt-in group and 441 to the opt-out group. In the intention-to-treat analysis, there was no significant difference in the primary outcome of completed mammography at 100 days between the opt-out and opt-in groups (67 [15.2%] vs 66 [14.9%]; P = .90) or the secondary outcome of completed or scheduled mammography (84 [19%] vs 106 [24.0%]; P = .07). A higher number of referrals were canceled in the opt-out group compared with the opt-in group (104 [23.6%] vs 24 [5.4%]; P < .001). The restricted analysis demonstrated similar results except more veterans completed or scheduled mammography within 100 days in the opt-out group compared with the opt-in group (102 of 388 [26.3%] vs 80 of 415 [19.3%]; P = .02). Conclusions and Relevance: In this randomized clinical trial, an opt-out population-based breast cancer screening outreach approach compared with an opt-in approach did not result in a significant difference in mammography completion but did lead to substantially more canceled mammography referrals, increasing staff burden. Trial Registration: ClinicalTrials.gov Identifier: NCT05313737.

Changes in Primary Care Quality Associated With Implementation of the Veterans Health Administration Preventive Health Inventory.

Importance: The COVID-19 pandemic caused significant disruptions in primary care delivery. The Veterans Health Administration (VHA) launched the Preventive Health Inventory (PHI) program-a multicomponent care management intervention, including a clinical dashboard and templated electronic health record note-to support primary care in delivering chronic disease care and preventive care that had been delayed by the pandemic. Objectives: To describe patient, clinician, and clinic correlates of PHI use in primary care clinics and to examine associations between PHI adoption and clinical quality measures. Design, Setting, and Participants: This quality improvement study used VHA administrative data from February 1, 2021, through February 28, 2022, from a national cohort of 216 VHA primary care clinics that have implemented the PHI. Participants comprised 829 527 veterans enrolled in primary care in clinics with the highest and lowest decile of PHI use as of February 2021. Exposure: Templated electronic health record note documenting use of the PHI. Main Outcomes and Measures: Diabetes and blood pressure clinical quality measures were the primary outcomes. Interrupted time series models were applied to estimate changes in diabetes and hypertension quality measures associated with PHI implementation. Low vs high PHI use was stratified at the facility level to measure whether systematic differences in uptake were associated with quality. Results: A total of 216 primary clinics caring for 829 527 unique veterans (mean [SD] age, 64.1 [16.9] years; 755 158 of 829 527 [91%] were men) formed the study cohort. Use of the PHI varied considerably across clinics. The clinics in the highest decile of PHI use completed a mean (SD) of 32 997.4 (14 019.3) notes in the electronic health record per 100 000 veterans compared with 56.5 (35.3) notes per 100 000 veterans at the clinics in the lowest decile of use (P < .001). Compared with the clinics with the lowest use of the PHI, clinics with the highest use had a larger mean (SD) clinic size (12 072 [7895] patients vs 5713 [5825] patients; P < .001), were more likely to be urban (91% vs 57%; P < .001), and served more non-Hispanic Black veterans (16% vs 5%; P < .001) and Hispanic veterans (14% vs 4%; P < .001). Staffing did not differ meaningfully between high- and low-use clinics (mean [SD] ratio of full-time equivalent staff to clinician, 3.4 [1.2] vs 3.4 [0.8], respectively; P < .001). After PHI implementation, compared with the clinics with the lowest use, those with the highest use had fewer veterans with a hemoglobin A1c greater than 9% or missing (mean [SD], 6577 [3216] per 100 000 veterans at low-use clinics; 9928 [4236] per 100 000 veterans at high-use clinics), more veterans with an annual hemoglobin A1c measurement (mean [SD], 13 181 [5625] per 100 000 veterans at high-use clinics; 8307 [3539] per 100 000 veterans at low-use clinics), and more veterans with adequate blood pressure control (mean [SD], 20 582 [12 201] per 100 000 veterans at high-use clinics; 12 276 [6850] per 100 000 veterans at low-use clinics). Conclusions and Relevance: This quality improvement study of the implementation of the VHA PHI suggests that higher use of a multicomponent care management intervention was associated with improved quality-of-care metrics. The study also found significant variation in PHI uptake, with higher uptake associated with clinics with more racial and ethnic diversity and larger, urban clinic sites.

Implementation of a mailed faecal immunochemical test programme for colorectal cancer screening among Veterans.

BACKGROUND: Screening for colorectal cancer (CRC) with faecal immunochemical test (FIT) is effective at reducing CRC mortality. Unfortunately, the COVID-19 pandemic has been associated with deferred care, especially screening for CRC. AIM: We sought to develop a mailed FIT programme (MFP) to increase CRC screening and make recommendations for adoption across the Veterans Health Administration (VHA) and for other large healthcare systems. SETTING: 2 regional VA medical centres in California and Washington state. PARTICIPANTS: 5667 average risk veterans aged 50-75 overdue or due within 90 days for CRC screening. PROGRAMME DESCRIPTION: A multidisciplinary implementation team collaborated to mail an FIT kit to eligible veterans. Both sites mailed a primer postcard, and one site added an automated reminder call. PROGRAMME EVALUATION: We monitored FIT return and positivity rate, as well as impact of the programme on clinical staff. 34% of FIT kits were returned within 90 days and 7.8% were abnormal. DISCUSSION: We successfully implemented a population-based MFP at multiple regional VA sites and recommend that these efforts be spread across VA. Our model of regional leadership, facility champions and using centralised resources can be adaptable to other large healthcare systems. MFPs support catch-up from disrupted care by addressing access to CRC screening, unburden primary care visits and conserve limited procedural resources.

Association of High-Cost Health Care Utilization With Longitudinal Changes in Patient-Centered Medical Home Implementation.

Importance: In 2010, the US Veterans Health Administration (VHA) implemented one of the largest patient-centered medical home (PCMH) models in the United States, the Patient Aligned Care Team initiative. Early evaluations demonstrated promising associations with improved patient outcomes, but limited evidence exists on the longitudinal association of PCMH implementation with changes in health care utilization. Objective: To determine whether a change in PCMH implementation is associated with changes in emergency department (ED) visits, hospitalizations for ambulatory care-sensitive conditions (ACSCs), or all-cause hospitalizations. Design, Setting, and Participants: This cohort study used national patient-level data from the VHA and Centers for Medicare & Medicaid Services between October 1, 2012, and September 30, 2015. A total of 1 650 976 patients from 897 included clinics were divided into 2 cohorts: patients younger than 65 years who received primary care at VHA sites affiliated with a VHA ED and patients 65 years or older who were enrolled in both VHA and Medicare services. Exposures: Clinics were categorized on improvement or decline in PCMH implementation based on their Patient Aligned Care Team implementation progress index (Pi2) score. Main Outcomes and Measures: Change in the number of ED visits, ACSC hospitalizations, and all-cause hospitalizations among patients at each clinic site. Results: The study included a total of 1 650 976 patients, of whom 581 167 (35.20%) were younger than 65 years (mean [SD] age, 49.03 [10.28] years; 495 247 [85.22%] men) and 1 069 809 (64.80%) were 65 years or older (mean [SD] age, 74.64 [7.41] years; 1 050 110 [98.16%] men). Among patients younger than 65 years, there were fewer ED visits among patients seen at clinics that had improved PCMH implementation (110.8 fewer visits per 1000 patients; P < .001) and clinics that had somewhat worse implementation (69.0 fewer visits per 1000 patients; P < .001) compared with clinics that had no change in Pi2 score. There were no associations of change in Pi2 scores with all-cause hospitalizations or ACSC hospitalizations among patients younger than 65 years. In patients 65 years or older, those seen at clinics that had somewhat worse PCMH implementation experienced fewer ED visits (20.1 fewer visits per 1000 patients; P = .002) and all-cause hospitalizations (12.4 fewer hospitalizations per 1000 patients; P = .007) compared with clinics with no change in Pi2 score. There was no association between change in Pi2 score with ACSC hospitalizations among patients 65 years or older. Conclusions and Relevance: There were no consistent associations of change in Pi2 score with high-cost health care utilization. This finding highlights the key differences in measuring PCMH implementation longitudinally compared with cross-sectional study designs.

Reliance on Medicare Providers by Veterans after Becoming Age-Eligible for Medicare is Associated with the Use of More Outpatient Services.

OBJECTIVE: To estimate the effect of Medicare use on the receipt of outpatient services from 2001 through 2015 for a cohort of Veterans Administration (VA) users who became age-eligible for Medicare in 1998-2000. DATA SOURCES/STUDY SETTING: VA administrative data linked with Medicare claims for veterans who participated in the 1999 Large Health Survey of Enrolled Veterans. STUDY DESIGN: We coded each veteran as VA-reliant or Medicare-reliant based on the number of visits in each system and compared the health and social risk factors between VA-reliant and Medicare-reliant veterans. We used bivariate probit and instrumental variables models to estimate the association between a veteran's reliance on Medicare and the receipt of outpatient procedures in Medicare and the VA. PRINCIPAL FINDINGS: Veterans who chose to rely on the VA (n = 4,317) had substantially worse social and health risk factors than Medicare-reliant veterans (n = 2,567). Medicare reliance was associated with greater use of outpatient services for 24 of the 28 types of services considered. Instrumental variable estimates found significant effects of Medicare reliance on receipt of advanced imaging and cardiovascular testing. CONCLUSIONS: Expanded access to fee-for-service care in the community may be expensive, while the VA will likely continue to care for the most vulnerable veterans.

The long term impact of an end-of-life communication intervention among veterans with COPD.

OBJECTIVE: To assess if an end-of-life communication intervention with patients with COPD led to higher long-term documentation of advance care planning discussions at the end-of-life. BACKGROUND: We previously demonstrated that providing clinicians a patient-specific feedback form about patients' communication preferences improved the occurrence and quality of clinician communication about end-of-life care. METHODS: Among those individuals enrolled in the intervention study (2004-2007) who had died during the follow-up period (up to 2013), we assessed if patients in the intervention arm had more goals of care discussions and formal advance directives completed as compared to controls. We conducted logistic models accounting for provider level clustering, adjusting for age, FEV1, and race. RESULTS: Among the 376 patients in the study, 157 died (76 in the intervention arm, 81 in the control arm). Over an average duration of 3.6 years (from the time of the first study appointment to death), 115 (73%) patients engaged in 451 unique end-of-life care discussions. The intervention was not associated with a higher percentage of patients with documented end-of-life conversations (I:C 75% vs 72%, p = 0.63) or completion of advance care directives (26% vs 29%, p = 0.55). CONCLUSIONS: Despite initially improving the occurrence of end-of-life conversations, the intervention did not increase the documentation of subsequent conversations about end-of-life care, nor did it improve documentation of advance directives. Future research should focus on testing multi-faceted, longitudinal, system-level interventions to enhance conversations about goals of care that promote goal-concurrent care.
