Geriatric conditions and healthcare utilization among older adults living in subsidized housing.

BACKGROUND: Nearly 2.9 million older Americans with lower incomes live in subsidized housing. While regional and single-site studies show that this group has higher rates of healthcare utilization compared to older adults in the general community, little is known about healthcare utilization nationally nor associated risk factors. METHODS: We conducted a retrospective cohort study of Medicare beneficiaries aged ≥65 enrolled in the National Health and Aging Trends Study in 2011, linked to Medicare claims data, including individuals living in subsidized housing and the general community. Participants were followed annually through 2020. Outcomes were hospitalization, short-term skilled nursing facility (SNF) utilization, long-term care utilization, and death. Fine-Gray competing risks regression analysis was used to assess the association of subsidized housing residence with hospitalization and nursing facility utilization, and Cox proportional hazards regression analysis was used to assess the association with death. RESULTS: Among 6294 participants (3600 women, 2694 men; mean age, 75.5 years [SD, 7.0]), 295 lived in subsidized housing at baseline and 5999 in the general community. Compared to older adults in the general community, those in subsidized housing had a higher adjusted subdistribution hazard ratio [sHR] of hospitalization (sHR 1.21; 95% CI, 1.03-1.43), short-term SNF utilization (sHR 1.49; 95% CI, 1.15-1.92), and long-term care utilization (sHR 2.72; 95% CI, 1.67-4.43), but similar hazard of death (HR, 0.86; 95% CI, 0.69-1.08). Individuals with functional impairment had a higher adjusted subdistribution hazard of hospitalization and short-term SNF utilization and individuals with dementia and functional impairment had a higher hazard of long-term care utilization. CONCLUSIONS: Older adults living in subsidized housing have higher hazards of hospitalization and nursing facility utilization compared to those in the general community. Housing-based interventions to optimize aging in place and mitigate risk of nursing facility utilization should consider risk factors including functional impairment and dementia.

State scope of practice restrictions and nurse practitioner practice in nursing homes: 2012-2019.

Increased engagement of nurse practitioners (NPs) has been recommended as a way to address care delivery challenges in settings that struggle to attract physicians, such as primary care and rural areas. Nursing homes also face such physician shortages. We evaluated the role of state scope of practice regulations on NP practice in nursing homes in 2012-2019. Using linear probability models, we estimated the proportion of NP-delivered visits to patients in nursing homes as a function of state scope of practice regulations. Control variables included county demographic, socioeconomic, and health care workforce characteristics; state fixed effects; and year indicators. The proportion of nursing home visits conducted by NPs increased from 24% in 2012 to 42% in 2019. Expanded scope of practice regulation was associated with a greater proportion and total volume of nursing home visits conducted by NPs in counties with at least 1 NP visit. These relationships were concentrated among short-stay patients in urban counties. Removing scope of practice restrictions on NPs may address clinician shortages in nursing homes in urban areas where NPs already practice in nursing homes. However, improving access to advanced clinician care for long-term care residents and for patients in rural locations may require additional interventions and resources.

Emergency department visits by older adults receiving postacute care in skilled nursing facilities.

Skilled nursing facilities (SNF) represent a common postdischarge destination for hospitalized older adults. The goals of SNF care include the completion of extended skilled nursing care and physical rehabilitation to enable patients to safely return home. However, nearly one in four older adults discharged to SNF are rehospitalized and one in five seek care in the emergency department (ED) but are discharged back to SNF. Our aim was to measure the national prevalence and costs to Medicare of ED visits by SNF patients. Of the 1,551,703 Medicare beneficiaries discharged to SNF in 2019, 16.3% had an ED visit within 14 days (n = 253,104). Of those ED visits, 25.5% resulted in a same-day discharge back to SNF (n = 64,472), costing Medicare $24.6 million. Novel care models that can leverage SNF staff and resources while providing rapid diagnostic services are urgently needed.

Association between Timing of Clinical Evaluation by a Physician or Advanced Practitioner and Risk of Rehospitalization in Older Adults Admitted to a Skilled Nursing Facility Following Hospitalization: A Cohort Study.

OBJECTIVES: How transitional care services are provided to patients receiving post-acute care in skilled nursing facilities (SNFs) is not well understood. We aimed to determine the association of timing of physician or advanced practice provider (APP) visit after SNF admission with rehospitalization risk in a national cohort of older adults. DESIGN: Retrospective cohort study. SETTING AND PARTICIPANTS: 2,482,616 Medicare fee-for-service beneficiaries aged ≥66 years who entered an SNF for post-acute care following hospitalization. METHODS: We measured the relative risk of being rehospitalized within 14 days of SNF admission as a function of time to the first PAP visit, using time to follow-up as a time-dependent covariate, adjusted for patient demographics and clinical characteristics. We also evaluated whether findings extended across groups with different SNF prognosis on admission. RESULTS: Patients seen sooner after admission to an SNF (0-1 days) were less likely to be rehospitalized compared to patients seen later (≥2 days). The relative difference was similar across different risk groups. CONCLUSIONS AND IMPLICATIONS: Timely evaluation by a physician or APP after SNF admission may protect against rehospitalization. Investment in the workforce such as training programs, practice innovations, and equitable reimbursement for SNF visits after hospital discharge may mitigate labor shortages that were exacerbated by the COVID pandemic.

Use of Clinicians Who Focus on Nursing Home Care Among US Nursing Homes and Unplanned Rehospitalization.

Importance: The number of physicians and advanced practitioners who focus their practice in nursing homes (NHs), often referred to as "SNFists" (ie, physicians, nurse practitioners, and physician assistants concentrating their practice in the nursing home or skilled nursing facility [SNF] setting) has increased dramatically. Little is known about the association of the NH medical care delivery models that use SNFists with the quality of postacute care. Objective: To quantify the association between NH use of SNFists and facility-level, unplanned 30-day rehospitalization rates for patients receiving postacute care. Design, Setting, and Participants: This cohort study used Medicare fee-for-service claims for all hospitalized beneficiaries discharged to 4482 NHs from January 1, 2012, through December 31, 2019. The study sample comprised NHs that did not have patients under the care of SNFists as of 2012. The treatment group included NHs that adopted at least 1 SNFist by the end of the study period. The control group included NHs that did not have patients under the care of a SNFist during the study period. SNFists were defined as generalist physicians and advanced practitioners with 80% or more of their Medicare Part B services delivered in NHs. Statistical analysis was conducted from January 2022 to April 2023. Exposure: Nursing home adoption of 1 or more SNFists. Main Outcomes and Measures: The main outcome was the NH 30-day unplanned rehospitalization rate. A facility-level analysis was conducted using an event study approach to estimate the association of an NH adopting 1 or more SNFists with its unplanned 30-day rehospitalization rate, adjusting for patient case mix, facility, and market characteristics. Changes in patient case mix were examined in secondary analyses. Results: In this study of 4482 NHs, adoption of SNFists increased from 13.5% of facilities (550 of 4063) in 2013 to 52.9% (1935 of 3656) in 2018. Adjusted rehospitalization rates were not statistically different after SNFist adoption compared with before, with an estimated mean treatment effect of 0.05 percentage points (95% CI, -0.43 to 0.53 percentage points; P = .84). The share of Medicare-covered patients increased by 0.60 percentage points (95% CI, 0.21-0.99 percentage points; P = .003) in the year of SNFist adoption and by 0.54 percentage points (95% CI, 0.12-0.95 percentage points; P = .01) 1 year after adoption compared with NHs that did not adopt SNFists. The number of postacute admissions increased by 13.6 (95% CI, 9.7-17.5; P < .001) after SNFist adoption, but there was no statistically significant change in the acuity index. Conclusions and Relevance: This cohort study suggests that NH adoption of SNFists was associated with an increase in the number of admissions for postacute care but was not associated with a change in rehospitalization rates. This may represent a strategy by NHs to maintain rehospitalization rates while increasing the volume of patients receiving postacute care, which typically results in higher profit margins.

Potentially avoidable emergency department use by patients discharged to skilled nursing facilities.

One-third of patients discharged from hospitals to skilled nursing facilities (SNF) are sent back to the Emergency Department (ED) within 30 days. Little is known about those patients who are discharged from the ED directly back to SNF. We considered these ED visits as potentially avoidable since they did not result in observation or hospitalization stay. Using a retrospective chart review of 1010 patients with ED visits within 14-days of discharge to SNF from University of Pennsylvania health system (UPHS) in 2020-2021, we identified 202 patients with potentially avoidable ED visits among medical and surgical patients. The most common reasons for these ED visits were mechanical falls (17.3%), postoperative problems (16.8%), and cardiac or pulmonary complaints (11.4%). Future interventions to decrease avoidable ED visits from SNFs should aim to provide access for SNF patients to receive timely outpatient lab and imaging services and postoperative follow-ups.

Potentially Harmful Medication Prescribing by the Degree of Physician Specialization in Nursing Home Practice: An Observational Study.

OBJECTIVES: The use of anticholinergics, antipsychotics, benzodiazepines, and other potentially harmful medications (PHMs) is associated with particularly poor outcomes in nursing home (NH) residents with Alzheimer's disease and related dementias (ADRD). Our objective was to compare PHM prescribing by NH physicians and advanced practitioners who focus their practice on NH residents (NH specialists) vs non-NH specialists. DESIGN: Retrospective cohort study. SETTING AND PARTICIPANTS: We included a 20% random sample of Medicare beneficiaries with ADRD who resided in 12,278 US NHs in 2017. Long-stay NH residents with ADRD were identified using MDS, Medicare Parts A and B claims. Residents <65 years old or without continuous Part D coverage were excluded. METHODS: Physicians in generalist specialties and advanced practitioners with ≥90% of Part B claims for NH care were considered NH specialists. Residents were assigned to NH specialists vs non-NH specialists based on plurality of Part D claims submitted for that resident. Any PHM use (defined using the Beers Criteria) and the proportion of NH days on a PHM were modeled using generalized estimating equations. Models included resident demographics, clinical characteristics, cognitive and functional status, behavioral assessments, and facility characteristics. RESULTS: Of the 54,713 residents in the sample, 27.9% were managed by an NH specialist and 72.1% by a non-NH specialist. There was no statistically significant difference in any PHM use [odds ratio (OR) 0.97, 95% CI 0.93-1.02, P = .23]. There were lower odds of prolonged PHM use (OR 0.87, 95% CI 0.81-0.94, P < .001, for PHM use on >75% vs >0%-<25% of NH days) for NH specialists vs non-NH specialists. CONCLUSIONS AND IMPLICATIONS: Although the use of PHMs among NH residents with ADRD managed by NH specialists was not lower, they were less likely to receive PHMs over longer periods of time. Future work should evaluate the underlying causes of these differences to inform interventions to improve prescribing for NH residents.

Disparities in access to specialty care and emergency department use after hospital discharge to a skilled nursing facility.

BACKGROUND: Patterns in access to specialists among patients in skilled nursing facilities (SNFs) have not been previously described. OBJECTIVE: To measure access to outpatient specialty follow-up and subsequent emergency department (ED) visits by patient characteristics, including race/ethnicity and those who received specialty care during the hospitalization that preceded the SNF stay. DESIGN, SETTINGS, AND PARTICIPANTS: This retrospective cohort study used the minimum data set and 100% Medicare fee-for-service claims for beneficiaries admitted to an SNF between 2012 and 2014. Hospital stays for surgical procedures were excluded. MAIN OUTCOME AND MEASURES: The associations between ED visits, follow-up, and race/ethnicity were measured using logistic and linear regression, adjusting for patient demographic and clinical characteristics. RESULTS: The sample included 1,117,632 hospitalizations by Medicare beneficiaries ≥65 with a consult by a medical subspecialist followed by discharge to SNF. Of the sample, 85.4% were non-Hispanic White (NHW) and 14.6% were Black, indigenous, and people of color (BIPOC), according to Medicare beneficiary records. During the SNF stay, BIPOC patients had lower odds of specialty follow-up compared to NHW patients (odds ratio [OR]: 0.96, 95% confidence intervals [CI]: 0.94-0.99, p = .004). BIPOC patients had higher rates of ED visits compared to NHW patients (with follow-up: 24.1% vs. 23.4%, and without follow-up: 27.4% vs. 25.9%, p < .001). Lack of follow-up was associated with a 0.8 percentage point difference in ED visits between BIPOC and NHW patients (95% CI: 0.3-1.3, p = .003). CONCLUSIONS: There is a racial/ethnic disparity in subspecialty follow-up after hospital discharge to SNF that is associated with a higher rate of subsequent ED visits by BIPOC patients.

US Generalist Physicians and Groups That Focused Practice in a Single Care Setting: 2014-2017.

BACKGROUND: Some generalist physicians whose training prepared them for primary care practice increasingly practice in a facility (eg, hospitals, nursing homes); however, whether this trend was accompanied by a complimentary rise in generalist physicians who focused their practice on office-based care is unknown. OBJECTIVES: Our objective in this study was to examine trends in the prevalence of generalist physicians and physician groups that practice in a single setting. RESEARCH DESIGN: This was a retrospective cross-sectional study of generalist physicians trained in family medicine, internal medicine, or geriatrics. We used 2014-2017 billing data for Medicare fee-for-service beneficiaries to measure the proportion of all patient visits made by physicians in the following care settings: office, outpatient hospital department, inpatient hospital, and other sites. RESULTS: From 2014 to 2017, the proportion of generalist physicians who narrowed their practice to a single setting increased by 6.69% (from 62.80% to 67.00%, p for trend <0.001). In 2017, 4.63% of physician groups included more than 1 type of setting-based physicians. CONCLUSIONS: Generalist physicians treating older adults increasingly narrowed their practice focus to a single type of health care setting. This trend was not accompanied by growth among physician groups that included different types of setting-based physicians. Further evaluation of the consequences of these trends on the fragmentation of primary care delivery across different health care settings and primary care outcomes is needed.

Transitional care innovation for Medicaid-insured individuals: early findings.

BACKGROUND: Chronically ill adults insured by Medicaid experience health inequities following hospitalisation. LOCAL PROBLEM: Postacute outcomes, including rates of 30-day readmissions and postacute emergency department (ED), were higher among Medicaid-insured individuals compared with commercially insured individuals and social needs were inconsistently addressed. METHODS: An interdisciplinary team introduced a clinical pathway called 'THRIVE' to provide postacute wrap-around services for individuals insured by Medicaid. INTERVENTION: Enrolment into the THRIVE clinical pathway occurred during hospitalisation and multidisciplinary services were deployed into homes within 48 hours of discharge to address clinical and social needs. RESULTS: Compared with those not enrolled in THRIVE (n=437), individuals who participated in the THRIVE clinical pathway (n=42) experienced fewer readmissions (14.3% vs 28.4%) and ED visits (14.3% vs 28.8 %). CONCLUSION: THRIVE is a promising clinical pathway that increases access to ambulatory care after discharge and may reduce readmissions and ED visits.

Factors Associated with Potentially Harmful Medication Prescribing in Nursing Homes: A Scoping Review.

OBJECTIVES: To summarize current evidence regarding facility and prescriber characteristics associated with potentially harmful medication (PHM) use by residents in nursing homes (NHs), which could inform the development of interventions to reduce this potentially harmful practice. DESIGN: Scoping review. SETTING AND PARTICIPANTS: Studies conducted in the United States that described facility and prescriber factors associated with PHM use in NHs. METHODS: Electronic searches of PubMed/MEDLINE were conducted for articles published in English between April 2011 and November 2021. PHMs were defined based on the Beers List criteria. Studies testing focused interventions targeting PHM prescribing or deprescribing were excluded. Studies were characterized by the strengths and weaknesses of the analytic approach and generalizability. RESULTS: Systematic search yielded 1253 articles. Of these, 29 were assessed in full text and 20 met inclusion criteria. Sixteen examined antipsychotic medication (APM) use, 2 anticholinergic medications, 1 sedative-hypnotics, and 2 overall PHM use. APM use was most commonly associated with facilities with a higher proportion of male patients, younger patients, and patients with severe cognitive impairment, anxiety, depression, and aggressive behavior. The use of APM and anticholinergic medications was associated with low registered nurse staffing ratios and for-profit facility status. No studies evaluated prescriber characteristics. CONCLUSIONS AND IMPLICATIONS: Included studies primarily examined APM use. The most commonly reported facility characteristics were consistent with previously reported indicators of poor NH quality and NHs with patient case mix more likely to use PHMs.

Benzodiazepine and antipsychotic use among hospitalized older adults before versus after restricting visitation: March to May 2020.

BACKGROUND: Hospital visitation restrictions during the COVID-19 pandemic prompted concerns about unintended consequences for older patients, including an increased incidence of delirium and agitation. While first-line interventions for these conditions are non-pharmacologic, a lack of family support could result in increased use of benzodiazepines and antipsychotics, which are associated with poor outcomes in older adults. Little is known about the association of visitation policies with use of these medications among older adults. METHODS: We conducted a retrospective cross-sectional study among adults aged ≥65 hospitalized from March 1 through May 31, 2020 at four hospitals in the Mid-Atlantic. The dates of onset of visitation restrictions (i.e., hospital-wide guidelines barring visitors) were collected from hospital administrators. Outcomes were use of benzodiazepines and antipsychotics, assessed using patient-level electronic health record data. Using multivariable logistic regression with hospital and study-day fixed effects, the quasi-experimental study design leveraged the staggered onset of visitation restrictions across the hospitals to measure the odds of receiving each medication when visitors were versus were not allowed. RESULTS: Among 2931 patients, mean age was 76.6 years (SD, 8.3), 51.6% were female, 58.6% white, 32.5% black, and 2.6% Hispanic. Overall, 924 (31.5%) patients received a benzodiazepine and 298 (10.2%) an antipsychotic. The adjusted odds of benzodiazepine use was lower on days when visitors were versus were not allowed (adjusted odds ratio [AOR], 0.62; 95% CI, 0.39, 0.99). Antipsychotic use did not significantly differ between days when visitors were versus were not allowed (AOR, 0.98; 95% CI, 0.43, 2.21). CONCLUSIONS: Among older patients hospitalized during the first wave of the pandemic, benzodiazepine use was lower on days when visitors were allowed. These findings suggest that the presence of caregivers impacts use of potentially inappropriate medications among hospitalized older adults, supporting efforts to recognize caregivers as essential members of the care team.

Older adults' access to primary care: Gender, racial, and ethnic disparities in telemedicine.

BACKGROUND: In 2020, primary care practices adopted telemedicine as an alternative to in-person visits. Little is known about whether access to telemedicine was equitable, especially among older patients. Our objectives were to (1) examine older adults' use of telemedicine versus in-person primary care visits and (2) compare hospitalization for ambulatory care sensitive conditions (ACSCs) between the groups. METHODS: In this retrospective cross-sectional study of 17,103 patients aged ≥65 years seen at 32 clinics in the Mid-Atlantic, primary care patients were classified into two groups-telemedicine versus in person-based on the first visit between March and May 2020 and followed up for 14 days. Using multivariable logistic regression, we measured the odds of being seen via telemedicine versus in person as a function of patient demographics, comorbidities, and week of study period. We then measured the odds of ACSC hospitalization by visit modality. RESULTS: Mean age was 75.1 years (SD, 7.5), 60.6% of patients were female, 64.6% white, 28.1% black, and 2.0% Hispanic. Overall, 60.3% of patients accessed primary care via telemedicine. Black (vs. white) patients had higher odds of using telemedicine (adjusted odds ratio [aOR], 1.30; 95% CI, 1.14-1.47) and Hispanic (vs. not Hispanic) patients had lower odds (aOR, 0.63; 95% CI, 0.42-0.92). Compared with the in-person group, patients in the telemedicine group had lower odds of ACSC hospitalization (aOR, 0.78; 95% CI, 0.61-1.00). Among patients who used telemedicine, black patients had 1.43 higher odds of ACSC hospitalization (95% CI, 1.02-2.01) compared with white patients. Patients aged 85 or older seen via telemedicine had higher odds of an ACSC hospitalization (aOR, 1.60; 95% CI, 1.03-2.47) compared with patients aged 65-74. CONCLUSIONS: These findings support the use of telemedicine for primary care access for older adults. However, the observed disparities highlight the need to improve care quality and equity regardless of visit modality.

Characteristics of Nursing Homes by COVID-19 Cases Among Staff: March to August 2020.

OBJECTIVE: To measure the association between nursing home (NH) characteristics and Coronavirus Disease 2019 (COVID-19) prevalence among NH staff. DESIGN: Retrospective cross-sectional study. SETTING AND PARTICIPANTS: Centers for Disease Control and Prevention COVID-19 database for US NHs between March and August 2020, linked to NH facility characteristics (LTCFocus database) and local COVID-19 prevalence (USA Facts). METHODS: We estimated the associations between NH characteristics, local infection rates, and other regional characteristics and COVID-19 cases among NH staff (nursing staff, clinical staff, aides, and other facility personnel) measured per 100 beds, controlling for the hospital referral regions in which NHs were located to account for local infection control practices and other unobserved characteristics. RESULTS: Of the 11,858 NHs in our sample, 78.6% reported at least 1 staff case of COVID-19. After accounting for local COVID-19 prevalence, NHs in the highest quartile of confirmed resident cases (413.5 to 920.0 cases per 1000 residents) reported 18.9 more staff cases per 100 beds compared with NHs that had no resident cases. Large NHs (150 or more beds) reported 2.6 fewer staff cases per 100 beds compared with small NHs (<50 beds) and for-profit NHs reported 0.8 fewer staff cases per 100 beds compared with nonprofit NHs. Higher occupancy and more direct-care hours per day were associated with more staff cases (0.4 more cases per 100 beds for a 10% increase in occupancy, and 0.7 more cases per 100 beds for an increase in direct-care staffing of 1 hour per resident day, respectively). Estimates associated with resident demographics, payer mix, or regional socioeconomic characteristics were not statistically significant. CONCLUSIONS AND IMPLICATIONS: These findings highlight the urgent need to support facilities with emergency resources such as back-up staff and protocols to reduce resident density within the facility, which may help stem outbreaks.

Practice Trends and Characteristics of US Hospitalists From 2012 to 2018.

This cohort study uses Medicare data to assess trends and characteristics among hospitalists who shift practice to settings outside of the hospital.

Characterizing Physician Practice in Nursing Homes Using Claims-Based Measures: Correlation With Nursing Home Administrators' Perceptions.

Heterogeneity in physician practice within nursing homes (NHs) may explain variations in quality. However, data on physician practice organization in NHs are hard to obtain. We characterized NH physician practice using two claims-based measures: (a) concentration of NH care among physicians (measured by Herfindahl-Hirschman index of visits); and (b) physician NH practice specialization (measured by the proportion of a physician's visits to NHs). We examined the relationship between the measures and NH administrator perceptions of physician practice reported in the Shaping Long-Term Care in America (SLTCA) Survey. All 2011 Part B claims from 13,718 physicians who treated Medicare fee-for-service patients in 2,095 NHs in the SLTCA survey were analyzed. The median Herfindahl-Hirschman index was 0.44 (interquartile range [IQR] 0.28-0.70), and the median specialization was 38.1% (IQR 19.9% to 60.9%). NHs with higher physician specialization reported more frequent physician participation in care coordination activities. Claims-based measures could inform the study of NH physician practice.

Medical Care Delivery in U.S. Nursing Homes: Current and Future Practice.

The delivery of medical care services in U.S. nursing homes (NHs) is dependent on a workforce that comprises physicians, nurse practitioners, and physician assistants. Each of these disciplines operates under a unique regulatory framework while adhering to common standards of care. NH provider characteristics and their roles in NH care can illuminate potential links to clinical outcomes and overall quality of care with important policy and cost implications. This perspective provides an overview of what is currently known about medical provider practice in NH and organizational models of practice. Links to quality, both conceptual and established, are presented as is a research and policy agenda that addresses the gaps in the evidence base within the context of our ever-changing health care landscape.
