Analyses of Nursing Home Residents With HIV and Dementia Using the Minimum Data Set:

Understanding the Relationship Between Nursing Home Experience With Human Immunodeficiency Virus and Patient Outcomes

BACKGROUND

As the population with human immunodeficiency virus (HIV) continues to age, the need for nursing home (NH) care is increasing.

OBJECTIVES

To assess whether NH's experience in treating HIV is related to outcomes.

RESEARCH DESIGN

We used claims and assessment data to identify individuals with and without HIV who were admitted to NHs in 9 high HIV prevalent states. We classified NHs into HIV experience categories and estimate the effects of NH HIV experience on patient's outcomes. We applied an instrumental variable using distances between each individual's residence and NHs with different HIV experience.

SUBJECTS

In all, 5,929,376 admissions for those without HIV and 53,476 admissions for residents with HIV.

MEASURES

Our primary outcomes were 30-day hospital readmissions, likelihood of becoming a long stay resident, and 180-day mortality posthospital discharge.

RESULTS

Residents with HIV tended to have poorer outcomes than residents without HIV, regardless of the NH they were admitted to. Residents with HIV admitted to high HIV experience NHs were more likely to be readmitted to the hospital than those admitted to NHs with lower HIV experience (19.6% in 0% HIV NHs, 18.7% in 05% HIV NHs and 22.9% in 5%-50% HIV NHs).

CONCLUSIONS

Residents with HIV experience worse outcomes in NHs than residents without HIV. Increased HIV experience was not related to improved outcomes.

The Quality of Nursing Homes That Serve Patients With Human Immunodeficiency Virus

BACKGROUND/OBJECTIVES

As the national population of persons living with human immunodeficiency virus (HIV) ages, they will require greater postacute and long-term care use. Little is known about the quality of nursing homes (NHs) to which patients with HIV are admitted. In this study, we assess the association between the number of persons with HIV admitted annually to a given NH (HIV concentration) and that NH's quality outcomes.

DESIGN

A cross-sectional comparative study.

SETTING

NHs in nine states, from 2001 to 2012.

PARTICIPANTS

A total of 46 918 NH-years accounting for 67 301 admissions by patients with HIV.

MEASUREMENTS

We used 100% Medicaid Analytic Extract, Minimum Dataset 2.0 and 3.0, and Medicare claims from 2001 to 2012 from nine states to examine the association between HIV concentration and NH quality. Persons were classified as HIV positive on the basis of all available data sources, and a NH's percentage of new admissions with HIV was calculated (HIV concentration). We then compared differences in star ratings, rehospitalization rates, NH survey deficiencies, and restraint use by a NH's percentage of admissions with HIV, using linear random effects models.

RESULTS

After adjusting for NH characteristics, zip code characteristics, and state and year fixed effects, NHs with greater than 0% to 5% of admissions with HIV had a 0.6 lower star rating (P < .001), and a 0.4% percentage point higher 30-day rehospitalization rate (P < .01), compared to those with no HIV admissions. NHs with 5% to 50% of admissions with HIV had 7.0 more deficiencies (P < .001), a 0.1 lower star rating (P < .001), and a 1.5 percentage point higher rehospitalization rate (P < .001).

CONCLUSION

Persons with HIV were generally admitted to lower-quality NHs compared to persons without HIV. More efforts are needed to ensure that persons with HIV have access to high-quality NHs. J Am Geriatr Soc 67:2615-2621, 2019.

Nursing Home Residents by Human Immunodeficiency Virus Status: Characteristics, Dementia Diagnoses, and Antipsychotic Use

OBJECTIVES

Given an aging human immunodeficiency virus (HIV) population, we aimed to determine the prevalence of HIV for long-stay residents in US nursing homes (NHs) between 2001 and 2010 and to compare characteristics and diagnoses of HIV-positive (HIV+) and negative (HIV-) residents. Also, for residents with dementia diagnoses, we compared antipsychotic (APS) medication receipt by HIV status.

DESIGN

A cross-sectional comparative study.

SETTING

NHs in the 14 states accounting for 75% of persons living with HIV.

PARTICIPANTS

A total of 9 245 009 long-stay NH residents.

MEASUREMENTS

Using Medicaid fee-for-service claims data in the years 2001 to 2010, together with Medicare resident assessment and Chronic Condition Warehouse data, we identified long-stay (more than 89 days) NH residents by HIV status and dementia presence. We examined dementia presence by age groups and APS medication receipt by younger (aged younger than 65 years) vs older (aged 65 years or older) residents, using logistic regression.

RESULTS

Between 2001 and 2010, the prevalence of long-stay residents with HIV in NHs increased from 0.7% to 1.2%, a 71% increase. Long-stay residents with HIV were younger and less often female or white. For younger NH residents, rates of dementia were 20% and 16% for HIV+ and HIV- residents, respectively; they were 53% and 57%, respectively, for older residents. In adjusted analyses, younger HIV+ residents with dementia had greater odds of APS medication receipt than did HIV- residents (AOR = 1.3; 95% confidence interval [CI] = 1.2-1.4), but older HIV residents had lower odds (AOR = 0.9; 95% CI = 0.8-0.9).

CONCLUSION

The prevalence of long-stay HIV+ NH residents has increased over time, and given the rapid aging of the HIV population, this increase is likely to have continued. This study raises concern about potential differential quality of care for (younger) residents with HIV in NHs, but not for those aged 65 years and older. These findings contribute to the evidence base needed to ensure high-quality care for younger and older HIV+ residents in NHs.

Trajectory of Physical Functioning Among Persons Living With HIV in Nursing Homes

OBJECTIVE(S)

To examine the change in physical functional status among persons living with HIV (PLWH) in nursing homes (NHs) and how change varies with age and dementia.

DESIGN

Retrospective cohort study.

SETTING

NHs in 14 states in the United States.

PARTICIPANTS

PLWH who were admitted to NHs between 2001 and 2010 and had stays of ≥90 days (N = 3550).

MEASUREMENTS

We linked Medicaid Analytic eXtract (MAX) and Minimum Data Set (MDS) data for NH residents in the sampled states and years and used them to determine HIV infection. The main outcome was improvement in physical functional status, defined as a decrease of at least 4 points in the activities of daily living (ADL) score within 90 days of NH admission. Independent variables of interest were age and dementia (Alzheimer's disease or other dementia). Multivariate logistic regression was used, adjusting for individual-level covariates.

RESULTS

The average age on NH admission of PLWH was 58. Dementia prevalence ranged from 14.5% in the youngest age group (age <40 years) to 38.9% in the oldest group (age ≥70 years). Overall, 44% of the PLWH experienced ADL improvement in NHs. Controlling for covariates, dementia was related to a significantly lower likelihood of ADL improvement among PLWH in the oldest age group only: the adjusted probability of improvement was 40.6% among those without dementia and 29.3% among those with dementia (P < .01).

CONCLUSIONS/RELEVANCE

PLWH, especially younger persons, may be able to improve their ADL function after being admitted into NHs. However, with older age, PLWH with dementia are more physically dependent and vulnerable to deterioration of physical functioning in NHs. More and/or specialized care may be needed to maintain physical functioning among this population. Findings from this study provide NHs with information on care needs of PLWH and inform future research on developing interventions to improve care for PLWH in NHs.
