Home and Community-Based Service Use Varies by Health Care Team and Comorbidity Level of Veterans with Dementia

Home and community-based services (HCBSs) such as home care and adult day centers are vital to supporting adults with dementia in community settings. We investigated whether HCBS use (use of both home care and adult day, use of one service, and use of neither service) varied between adults receiving care from three types of health-care teams with case management from social workers and nurses, and by comorbidity level, using 2019 data of 143,281 patients with dementia in the Veterans Health Administration. We compared HCBS use by patients' type of case-managed team (Home-Based Primary Care, geriatrics-based primary care, and dementia-focused specialty care) to patients in none of these teams, stratified by patients' non-dementia comorbidities (<4 or ≥4). Each type of health-care team was associated with both home care and adult day services, at each level of comorbidity. Home-Based Primary Care was most consistently associated with other forms of HCBS use, followed by Dementia Clinics and geriatrics-based primary care, for patients with ≥4 non-dementia comorbidities. Our findings suggest that case management in primary and specialty care settings is a contributor to the use of critical community supports by patients with the most complex needs.

Trajectories of care and outcomes of Veterans receiving home-based primary care

BACKGROUND

Veterans Affairs (VA) home-based primary care (HBPC) provides comprehensive longitudinal care to patients with complex, chronic disabling disease. While enrollment is associated with lower hospitalization rates and costs, detailed trajectories have not been well described.

METHODS

We performed a longitudinal descriptive study of patients newly enrolled in VA HBPC in fiscal year (FY) 2015. We extracted demographics, comorbidities, functional status, and social supports from VA and Medicare data and examined patterns of care and clinical outcomes, including hospital, nursing home (NH), hospice use and mortality from FY2015-2017. We present results using descriptive statistics, alluvial plots, and heat maps.

RESULTS

We identified 10,571 HBPC enrollees in FY2015; mean age was 77.7. HBPC patients commonly had chronic medical conditions with high self-management burden (e.g., diabetes 48.2%) and disabling conditions such as dementia (39.3%). Over half had ≥2 deficits in activities of daily living, 46% had caregivers with functional limitations or no caregiver, and 25% resided in a socially deprived area. Patients experienced variable care trajectories. Mean time enrolled in HBPC was 331 days, 8.3% of patients were discharged after 3 months, and 22.8% stayed enrolled for over 2 years. Institutional health care use declined in the 6 months after initial enrollment: (e.g., hospital: 41%-25%, NH: 34%-11%). At 2 years, 36% of patients had died; among decedents, 58% received hospice and 72% died in a non-institutional setting. In the last 180 days of life, 84% of time was spent at home, and once enrolled in hospice, 97% of time was spent outside of institutional care.

CONCLUSIONS

HBPC patients experience highly variable care trajectories but on average have reductions in acute care use and spend a majority of time in non-institutional settings. These data allow for a nuanced understanding of HBPC, providing a platform for monitoring, evaluating, and improving program function.

National Cohort Study of Homebound Persons Living With Dementia: Antibiotic Prescribing Trends and Opportunities for Antibiotic Stewardship

Background

Over 7 million older Americans are homebound. Managing infections in homebound persons presents unique challenges that are magnified among persons living with dementia (PLWD). This work sought to characterize antibiotic use in a national cohort of PLWD who received home-based primary care (HBPC) through the Veterans Health Administration.

Methods

Administrative data identified veterans aged ≥65 years with ≥2 physician home visits in a year between 2014 and 2018 and a dementia diagnosis 3 years before through 1 year after their initial HBPC visit. Antibiotics prescribed orally, intravenously, intramuscularly, or by enema within 3 days of an HBPC visit were assessed from the initial HBPC visit to death or December 31, 2018. Prescription fills and days of therapy (DOT) per 1000 days of home care (DOHC) were calculated.

Results

Among 39 861 PLWD, the median age (interquartile range [IQR]) was 85 (78-90) years, and 15.0% were Black. Overall, 16 956 (42.5%) PLWD received 45 122 prescription fills. The antibiotic use rate was 20.7 DOT per 1000 DOHC. Telephone visits and advanced practice provider visits were associated with 30.9% and 42.0% of fills, respectively. Sixty-seven percent of fills were associated with diagnoses for conditions where antibiotics are not indicated. Quinolones were the most prescribed class (24.3% of fills). The overall median length of therapy (IQR) was 7 (7-10) days. Antibiotic use rates varied across regions. Within regions, the median annual antibiotic use rate decreased from 2014 to 2018.

Conclusions

Antibiotic prescriptions were prevalent in HBPC. The scope, appropriateness, and harms of antibiotic use in homebound PLWD need further investigation.

Impact of a clinical pharmacist on medication safety in mental health Hospital-in-the-Home: a retrospective analysis

BACKGROUND

Integration of clinical pharmacists into multidisciplinary Mental Health Hospital-in-the-Home teams is increasing but little is known about the medication safety contribution these pharmacists make.

AIM

To evaluate whether clinical pharmacist involvement in a Mental Health Hospital-in-the-Home service improved medication safety key performance indicators.

METHOD

Medical records were retrospectively reviewed of all patients admitted to 2 Western Australian Mental Health Hospital-in-the-Home services from September to November 2015. SITE 1: was a 16-bed service incorporating a clinical pharmacist as part of its multidisciplinary team. SITE 2: was a similarly structured 18-bed service but without clinical pharmacist involvement. The primary outcome measure was completion of medication safety key performance indicators obtained from the Western Australian Government Pharmaceutical Review Policy and mental health-specific best practice guidelines.

RESULTS

Key performance indicators from Site 1 (n = 75 records), which incorporated a clinical pharmacist, demonstrated significantly (p < 0.001) higher rates of completion of medication reconciliation [65 (87%) versus 17 (29%)], accurate adverse drug reaction list [73 (97%) versus 34 (58%)], accurate discharge medication list [51 (74%) versus 18 (45%)], accurate medication profile [74 (99%) versus 40 (68%)] and medication chart review [74 (99%) versus 0 (0%)] than Site 2 (n = 59).

CONCLUSION

Integrating a clinical pharmacist into a Mental Health Hospital-in-the-Home program significantly improved achievement of medication safety key performance indicators.
