Key Points

Question

Is private equity acquisition of nursing homes associated with the quality or cost of care for long-stay nursing home residents?

Findings

In this cohort study with difference-in-differences analysis of 9864 US nursing homes, including 9632 residents in 302 nursing homes acquired by private equity firms and 249 771 residents in 9562 other for-profit nursing homes without private equity ownership, private equity acquisition of nursing homes was associated with higher costs and increases in emergency department visits and hospitalizations for ambulatory sensitive conditions.

Meaning

This study suggests that more stringent oversight and reporting on private equity ownership of nursing homes may be warranted.

Abstract

Importance

Private equity firms have been acquiring US nursing homes; an estimated 5% of US nursing homes are owned by private equity firms.

Objective

To examine the association of private equity acquisition of nursing homes with the quality and cost of care for long-stay residents.

Design, Setting, and Participants

In this cohort study of 302 private equity nursing homes with 9632 residents and 9562 other for-profit homes with 249 771 residents, a novel national database of private equity nursing home acquisitions was merged with Medicare claims and Minimum Data Set assessments for the period from 2012 to 2018. Changes in outcomes for residents in private equity–acquired nursing homes were compared with changes for residents in other for-profit nursing homes. Analyses were performed from March 25 to June 23, 2021.

Exposure

Private equity acquisitions of 302 nursing homes between 2013 and 2017.

Main Outcomes and Measures

This study used difference-in-differences analysis to examine the association of private equity acquisition of nursing homes with outcomes. Primary outcomes were quarterly measures of emergency department visits and hospitalizations for ambulatory care–sensitive (ACS) conditions and total quarterly Medicare costs. Antipsychotic use, pressure ulcers, and severe pain were examined in secondary analyses.

Results

Of the 259 403 residents in the study (170 687 women [65.8%]; 211 154 White residents [81.4%]; 204 928 residents [79.0%] dually eligible for Medicare and Medicaid; mean [SD] age, 79.3 [5.6] years), 9632 residents were in 302 private equity–acquired nursing homes and 249 771 residents were in 9562 other for-profit homes. The mean quarterly rate of ACS emergency department visits was 14.1% (336 072 of 2 383 491), and the mean quarterly rate of ACS hospitalizations was 17.3% (412 344 of 2 383 491); mean (SD) total quarterly costs were $8050.00 ($9.90). Residents of private equity nursing homes experienced relative increases in ACS emergency department visits of 11.1% (1.7 of 15.3; 1.7 percentage points; 95% CI, 0.3-3.0 percentage points; P = .02) and in ACS hospitalizations of 8.7% (1.0 of 11.5; 1.0 percentage point; 95% CI, 0.2-1.1 percentage points; P = .003) compared with residents in other for-profit homes; quarterly costs increased 3.9% (270.37 of 6972.04; $270.37; 95% CI, $41.53-$499.20; P = .02) or $1081 annually per resident. Private equity acquisition was not significantly associated with antipsychotic use (−0.2 percentage points; 95% CI, −1.7 to 1.4 percentage points; P = .83), severe pain (0.2 percentage points; 95% CI, −1.1 to 1.4 percentage points; P = .79), or pressure ulcers (0.5 percentage points; 95% CI, −0.4 to 1.3 percentage points; P = .30).

Conclusions and Relevance

This cohort study with difference-in-differences analysis found that private equity acquisition of nursing homes was associated with increases in ACS emergency department visits and hospitalizations and higher Medicare costs.

This cohort study uses a national database of private equity nursing home acquisitions as well as Medicare data to examine the association of private equity acquisition of nursing homes with the quality and cost of care for long-stay residents.

Introduction

Private equity (PE) investment in US health care has grown dramatically, with $750 billion in deals from 2010 to 2019.¹ These investments have concerned policy makers because PE firms often create complicated asset, management, and operating structures that may avoid transparency and accountability in patient care. A major target of PE firms has been nursing homes²: an estimated 5% of US nursing homes have PE ownership.³ For-profit companies are the predominant operators of nursing homes. A large body of research has indicated that for-profit ownership of nursing homes is associated with lower-quality long-term care compared with nonprofit ownership of nursing homes,^4,5 but little is known about differences in the quality of long-term care provided by PE-owned nursing homes compared with other for-profit nursing homes.

Over half of older adults will eventually stay in a nursing home for postacute or long-term care,⁶ and 12.5% of physicians provide at least some care in these facilities.⁷ There are 1.3 million long-stay nursing home residents in the US, with 90% being 65 years of age or older.⁸ Annual Medicaid expenditures on long-term care total $57 billion⁹ and include the cost of nursing home care for 60% of residents nationally.⁸ High rates of emergency department (ED) visits and hospitalization among residents, which often reflect poor quality long-term care, are associated with a disproportionate share of Medicare spending on this population.^10,11,12 For these reasons, policy makers have expressed concern about PE acquisitions of nursing homes,^13,14 concern that has been heightened by the toll of the COVID-19 pandemic on residents of these facilities.¹⁵

Private equity firm–owned nursing homes may operate differently than other for-profit homes, potentially improving or worsening the quality of care. Private equity firms seek high annual returns of 20% or more.¹⁶ The pressure to generate high short-term profits could lead to PE firm–owned nursing homes reducing staffing, services, supplies, or equipment, which may have an adverse association with quality of care,^3,17 whereas non-PE for-profit nursing homes may have business strategies with longer time horizons. Nursing homes purchased by PE firms may be responsible for the debt used by the PE firm as part of a leveraged buyout to acquire the facilities, thereby reducing their financial resources.¹⁸ Opponents of PE ownership are also concerned that PE firms may not be experienced in nursing home care,² or that they will focus more attention on postacute care and less on long-term care because Medicare reimbursements for patients receiving postacute care are much higher compared with Medicaid payments for long-stay residents.

Conversely, PE acquisitions of nursing homes may lead to higher-quality care through better management and improvements in health information technology capabilities.¹⁹ Private equity firms may also provide financial and legal resources to improve regulatory compliance, an area in which many nursing homes persistently underperform.²⁰

The results of prior studies of PE firm ownership and nursing home quality have been inconsistent.^{2,3,21,22,23,24,25,26} To our knowledge, there have been no national studies of the association between PE firm nursing home ownership and the quality and cost of care for long-stay residents. We used a national sample of long-stay nursing home residents from 2012 through 2018 to compare changes in the quality and cost of care for those in PE firm–acquired nursing homes with residents in for-profit nursing homes without PE investment.

Methods

Data Sources

In this cohort study, we identified PE firm nursing home acquisitions using a previously established method (eAppendix in the Supplement).³ Acquisitions occurring from 2010 to 2020 were identified using the S&P Capital IQ, Irving Levin Associates Health Care M&A, and Centers for Medicare & Medicaid Services (CMS) Nursing Home Compare Ownership databases, followed by web-based searches. These databases report transactions, including the acquisition announcement date, the name of the acquired nursing home, and the platform nursing home that acquired the facility or the PE firm that owned it. The Nursing Home Compare database provides the CMS Certification Number, nursing home name, address, owner name, and the date that ownership began. This study was approved by the institutional review board of Weill Cornell Medical College, waiving informed consent. The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) reporting guideline was followed.

We used Medicare fee-for-services claims and Minimum Data Set (MDS) assessments for a nationally representative 20% random sample of beneficiaries from 2012 through 2018. The claims came from the Medicare Provider Analysis and Review File for inpatient stays, the Medicare Carrier File for professional claims, the Medicare Outpatient File for institutional outpatient claims, and the Medicare Hospice File. The Medicare Master Beneficiary Summary File provided information on enrollment, demographics, reason for Medicare entitlement, and chronic and disabling conditions. Minimum Data Set assessments were used to identify long-stay residents (see definition below). These assessments are completed on nursing home admission and at least quarterly thereafter. Medicare claims and MDS assessments were merged using beneficiary identifiers. Measures of nursing home characteristics from Brown University’s LTCFocus²⁷ were then merged using nursing home CMS Certification Numbers.

Study Population

Study participants were long-stay residents, defined as Medicare beneficiaries enrolled in Parts A and B with stays in the same nursing home of 100 days or more, with 10 days or fewer outside the nursing home during this period. Residents aged 65 years or younger were excluded because they have conditions that differ from the broader long-stay population.^{28,29,30,31,32} Similarly, residents of hospital-based nursing homes were excluded (eFigure in the Supplement).^33,34

Study Variables

Outcome Measures

Outcome measures for the quality and total cost of care were chosen a priori. For our primary analyses, quality outcomes included binary measures for any ambulatory care–sensitive (ACS) ED visit in a given quarter and any ACS hospitalization in a given quarter.³⁵ These events should be largely, although not completely, preventable with appropriate care. Our measure of total quarterly costs was constructed by summing Medicare spending on inpatient, outpatient, postacute, hospice, and professional services in addition to laboratory tests. Although Medicaid covers long-term care in nursing homes for many residents, these costs are generally fixed daily payments, and poorer quality long-term care is likely reflected in increased spending for Medicare-covered services rather than in Medicaid spending because Medicare pays for ED visits and hospitalizations.¹²

In secondary analyses, we examined additional quality outcomes, including dichotomous measures for any antipsychotic medication use, presence of a pressure ulcer, and self-reported severe pain (values >6 on a 10-point pain scale, where 0 indicates no pain and 10 indicates the worst pain). We examined these outcomes owing to their relevance for long-stay residents, as indicated in the literature,^36,37,38,39 but include them in secondary analyses because they are self-reported by nursing homes and may therefore be biased.

Resident and Nursing Home Characteristics

Resident characteristics included age, race and ethnicity, sex, dual eligibility for Medicare and Medicaid, indicators for 66 chronic and potentially disabling conditions used for risk adjustment (eTable 2 in the Supplement), activities of daily living score at initial assessment (range, 1-28, where a higher score indicates a greater need for assistance with activities of daily living), and severe cognitive impairment (score >3 on the 4-point Cognitive Function Scale, where 1 indicates mild impairment and 4 indicates severe impairment).⁴⁰ Information on race and ethnicity in Medicare claims is generally collected from the Social Security Administration. We included measures for White and Black individuals. A third category for all other race and ethnicity categories (Asian, Hispanic, North American Native, and other) in Medicare claims was also included; we did not use separate measures for these groups because they are not accurately identified in Medicare claims.⁴¹ Nursing home characteristics included occupancy rate, multifacility chain affiliation, total number of beds, and terciles of the distributions of the percentage of patients covered by Medicare and the percentage covered by Medicaid.

Statistical Analysis

Statistical analyses were conducted using Stata MP, version 16.1 (StataCorp LLC). Analyses were performed from March 25 to June 23, 2021. Our treatment group included residents of nursing homes acquired by PE firms between 2013 and 2017. The control group included residents of for-profit nursing homes without PE ownership and located in a Hospital Referral Region with at least 1 PE firm–owned nursing home. We excluded nursing homes acquired by PE firms prior to 2013 and after 2017 so that all facilities in the treatment group had at least 1 year of data before (2012) and after acquisition (2018). If a nursing home was reacquired by a PE firm during our study period, we considered only the first acquisition in the treatment group. Nursing homes reacquired in 2013 or later after being acquired prior to 2013 were excluded.

We conducted 4 analyses. First, we examined the prevalence and geographical distribution of PE firm nursing home acquisitions between 2013 and 2017. Second, we compared resident and facility characteristics of PE and non-PE facilities in 2012 (before acquisition) to assess whether acquired nursing homes were different than nonacquired homes. Third, we compared the resident and facility characteristics of preacquisition nursing homes with postacquisition nursing homes using t tests for continuous variables and proportion tests for categorical variables. Fourth, we used a difference-in-differences approach to examine changes in outcomes associated with PE firm acquisition. Our variable of interest was an interaction between an indicator identifying PE firm–acquired nursing homes and an indicator for the postacquisition period; the corresponding estimate represents the association of PE acquisition with the outcome. Other covariates included resident and nursing home characteristics in addition to fixed effects for quarter, year, nursing home, Hospital Referral Region, and Hospital Referral Region interaction with year.

We used linear regression models for all outcomes, with SEs clustered at the nursing home level. The unit of analysis was the resident quarter for ACS ED visits, ACS hospitalizations, and total costs. In the secondary analyses, antipsychotic use, presence of a pressure ulcer, and severe pain occurring between nursing home admission and the first quarterly MDS assessment were examined. For unadjusted and adjusted results, relative differences were calculated by dividing each estimate by the unadjusted mean of the outcome in the preacquisition period.

We conducted 3 sensitivity analyses. The first addressed potential measurement error in the acquisition date. In some cases, we captured the date on which an acquisition was publicly announced, which may not be the exact date a nursing home was acquired. We addressed this issue by excluding the calendar year of the announced acquisition as a washout period. The second analysis included only nursing homes present in all years of the study period to mitigate the possibility of results being associated with facilities entering and leaving the sample. The third analysis compared differences in preacquisition outcome trends between residents of PE firm–owned and non-PE firm–owned nursing homes to test the parallel trends assumption for our difference-in-differences approach. All P values were from 2-sided tests and results were deemed statistically significant at P < .05.

Results

PE Investment in Nursing Homes

The Figure presents the geographical distribution of PE firm nursing home acquisitions between 2013 and 2017. We identified 79 PE transactions (eTable 1 in the Supplement), representing 302 nursing homes and 37 states, concentrated mostly in California, Kentucky, Massachusetts, Ohio, Tennessee, Texas, and Washington.

Characteristics of Residents and Nursing Homes

Table 1 presents resident and nursing home characteristics for the entire sample (pooled sample, 2012-2018) and for PE firm–owned and non-PE firm–owned for-profit nursing homes both before acquisition (2012) and after acquisition (2018). Of the 259 403 residents in the study, 170 687 (65.8%) were women, 211 154 (81.4%) were White, and 204 928 (79.0%) were dually eligible for Medicare and Medicaid; the mean (SD) age was 79.3 (5.6) years. In 2012, there were 289 nursing homes that were later acquired by PE firms and 7954 for-profit homes that were never acquired. In 2018, there were 295 PE firm–owned nursing homes and 8323 for-profit homes that were never acquired by PE firms. During the study period (2012-2018), there was a total of 9632 long-stay residents in 302 PE firm–owned nursing homes and 249 771 residents in 9562 non-PE firm–owned nursing homes.

In the pooled sample, nursing homes had a mean (SD) of 130.5 (63.7) beds and a mean (SD) occupancy rate of 82.7% (12.3%); 59.7% of facilities (5889 of 9864) were part of a chain (Table 1). Residents had a mean (SD) baseline activities of daily living score of 15.9 (6.7); 259 residents (0.1%) had severe cognitive impairment, and 108 690 (41.9%) were 85 years of age or older. Prior to acquisition, 75.8% of PE firm–owned nursing homes (219 of 289) and 57.4% of non-PE firm–owned nursing homes (4566 of 7954) were part of a chain. Private equity firm–owned nursing homes had a mean (SD) total bed count of 135.4 (69.5), and non-PE firm–owned nursing homes had a mean total bed count of 132.4 (62.6). A larger percentage of PE nursing homes was in the highest tercile of the percentage of residents covered by Medicare (41.2% vs 34.3%). Resident mean (SD) baseline activities of daily living scores for PE firm–owned and non-PE firm–owned nursing homes were 16.3 (7.2) and 15.7 (7.3), respectively. The mean percentage of Black residents, female residents, and residents aged 85 years or older were 12.4% (274 of 2209), 65.4% (1445 of 2209), and 36.2% (800 of 2209), respectively, for PE firm–owned nursing homes and 15.7% (9963 of 63 461), 67.8% (43 027 of 63 461), and 39.0% (24 750 of 63 461), respectively, for non-PE firm–owned nursing homes.

After acquisition, PE firm–owned nursing homes had a 1.5% higher mean occupancy rate and 6.4% more facilities affiliated with chains compared with non-PE firm–owned homes (Table 1). The mean number of beds of PE firm–owned nursing homes was 11.9 beds lower after acquisition. Following acquisition, PE firm–owned nursing homes had a 7.6% decrease in the lowest tercile for the percentage of residents covered by Medicaid and a 7.3% increase in the highest tercile for the percentage of residents covered by Medicaid.

Changes in Outcomes After Acquisition

Table 2 presents unadjusted and adjusted difference-in-differences results. Among all residents, mean quarterly rates of ACS ED visits and ACS hospitalizations, respectively, were 14.1% (336 072 of 2 383 491) and 17.3% (412 344 of 2 383 491); mean (SD) total quarterly Medicare costs were $8050.00 ($9.90). Preacquisition, there were no statistically significant differences in unadjusted outcomes. In the unadjusted difference-in-differences results, PE firm–owned nursing homes had a 13.1% relative increase in ACS ED visits (2.0 of 15.3; 2.0 percentage points; 95% CI, 1.0-4.0 percentage points; P = .01) and a 10.4% relative increase in ACS hospitalizations (1.2 of 11.5; 1.2 percentage point; 95% CI, 0.01-2.3; P = .04) compared with changes during the same time period in non-PE firm–owned nursing homes. There was no statistically significant difference in the unadjusted comparison of total costs ($94.02; 95% CI, −$392.42 to $580.50; P = .85).

Linear regressions were used for estimation. All models included the following covariates: age group (65-69, 70-74, 75-79, 80-84, and ≥85 years), race and ethnicity (Black, White, other non-White race [Asian, Hispanic, North American Native, and other]), sex, dual eligibility for Medicare and Medicaid, indicators for 66 chronic and disabling conditions used for risk adjustment (see eTable 2 in the Supplement for a list of the chronic conditions), activities of daily living score at initial assessment (range, 1-28, where a higher score indicates a greater need for assistance with activities of daily living)), and severe cognitive impairment (scores >3 on the 4-point Cognitive Function Scale). Nursing home characteristics included occupancy rate, an indicator for multifacility affiliation, total number of beds, and terciles of the distributions of the percentage of patients covered by Medicare and the percentage covered by Medicaid. Other covariates included fixed effects for quarter, year, nursing home, Hospital Referral Region, and Hospital Referral Region interaction with year. The unit of analysis is at the resident-quarter level. Standard errors were adjusted for clustering at the level of the nursing home.

^{^b}

The pooled sample consists of all resident observations from 2012 to 2018.

^{^c}

Relative changes were derived from the sample by dividing the adjusted estimates for all outcomes by the unadjusted mean of the outcomes in the preacquisition period (2012).

In adjusted differences-in-differences comparisons, PE firm acquisition was associated with an 11.1% relative increase in ACS ED visits (1.7 of 15.3; 1.7 percentage points; 95% CI, 0.3-3.0 percentage points; P = .02), an 8.7% relative increase in ACS hospitalizations (1.0 of 11.5; 1.0 percentage point; 95% CI, 0.2-1.1 percentage points; P = .003), and a 3.9% relative increase in total quarterly costs ($270.37 of $6972.04; $270.37; 95% CI, $41.53-$499.20; P = .02) (Table 2).

In the secondary analyses, there were no statistically significant adjusted estimates associated with PE firm acquisition of nursing homes in the use of antipsychotics (−0.2 percentage points; 95% CI, −1.7 to 1.4 percentage points; P = .83), pressure ulcers (0.5 percentage points; 95% CI, −0.4 to 1.3; P = .30), or severe pain (0.2 percentage points; 95% CI, −1.1 to 1.4 percentage points; P = .79) (Table 3).

Sensitivity Analyses

When a washout period for the year of PE firm acquisition was used, the results remained mainly consistent with our primary analyses, although the estimate for total costs was no longer statistically significant (eTable 3 in the Supplement). After limiting the sample to nursing homes present in all years of the study period (275 PE firm–owned nursing homes and 8407 for-profit, non-PE firm–owned homes), the results remained consistent with the primary analyses (eTable 4 in the Supplement). Tests to assess differences in preacquisition trends did not show any meaningful differences (eTable 5 in the Supplement).

Discussion

In this national cohort study with adjusted difference-in-differences analysis, long-stay residents of PE firm–owned nursing homes were 11.1% more likely to have an ACS ED visit and 8.7% more likely to experience an ACS hospitalization after acquisition compared with residents of non-PE firm–owned, for-profit nursing homes and had total Medicare costs that were 3.9% higher (approximately $1080 annually per resident). There were no differences between PE firm–owned nursing homes and non-PE firm–owned nursing homes in the likelihood of residents receiving antipsychotics, developing a pressure ulcer, or experiencing severe pain.

Prior studies of PE firm ownership and nursing home quality have had mixed results. Two studies that included samples of nursing homes from more than 1 decade ago did not find an association between PE firm ownership and quality based on MDS measures and the results of state inspections, but they did not assess ACS ED visits or hospitalizations or costs.^2,24 One of the studies did not distinguish between postacute and long-stay residents,² and the other study was limited to long-stay residents in Ohio.²⁴ Three studies found little evidence of an association between PE firm ownership and staffing,^2,21,22 while another study found reduced staffing at PE firm–owned nursing homes.²³ One recent working paper found increased registered nurse staffing and improved five-star ratings in PE firm–owned facilities in more competitive markets compared with non-PE firm–owned nursing homes.²⁶ A second working paper found PE firm ownership to be associated with increased mortality rates and higher costs for postacute patients, declines in five-star ratings, and slightly lower levels of direct care staffing, with the exception of an increase in registered nurse staffing.²⁵ A recent study during the COVID-19 pandemic found that PE firm–owned facilities performed similarly to those with other types of ownership in the number of COVID-19 cases and deaths, but PE firm–owned nursing homes had lower supplies of personal protective equipment.³

Public funds from the Medicare and Medicaid programs are the largest sources of nursing home revenue, but lack of transparency in ownership makes it very difficult to identify PE firm acquisitions of nursing homes and difficult to compare types of homes. The CMS requires that ownership stakes of 5% or more be reported in the Provider Enrollment, Chain, and Ownership System (PECOS). However, PECOS is not publicly available, even generally speaking, to researchers, and the information reported in PECOS is not regularly audited. Private equity firms frequently use complex corporate structures that make it difficult to identify related third parties.⁴² Tracking the amount of revenue for staffing, services, and supplies that goes to multiple related or co-owned entities that appear in PECOS as having ownership stakes in a nursing home is often not possible. Our findings suggest that more stringent oversight and reporting of related entities may be warranted. Policy makers might consider making more detailed ownership information available in outlets that provide consumers with information on nursing home quality, such as Nursing Home Compare.

Limitations

Our study has some limitations. First, we identified PE firm nursing home ownership using the S&P Capital IQ and Irving Levin Associates Health Care M&A databases, which rely on public announcements of acquisitions and may not include smaller acquisitions. Second, the CMS Nursing Home Ownership file may not always identify the parent company of a platform nursing home. In this case, nursing homes acquired on behalf of a PE firm by these platform nursing homes may appear to be for-profit nursing homes without PE firm ownership; this factor would bias our results toward the null. Third, we were unable to track PE firm exits from nursing homes, which also would bias our estimates toward no association of ownership with outcomes. However, PE firms usually sell acquired organizations within 3 to 7 years, so there were likely few exits during the 2013-2017 period used for our analyses.⁴³ Fourth, our study population included only residents participating in Medicare fee-for-service. As of 2018, 39% of all Medicare beneficiaries participated in Medicare Advantage,⁴⁴ although the participation rate of nursing home patients is estimated to be just over half the rate of the broader Medicare population.⁴⁵ Medicare Advantage claims are incomplete and therefore not ideal for measuring quality or costs.⁴⁶ Fifth, we did not compare PE firm–owned nursing homes with nonprofit nursing homes. However, previous research indicates that nonprofit nursing homes have better quality than for-profit nursing homes.^4,5

Conclusions

This cohort study suggests that PE firm–owned nursing homes provided somewhat lower-quality long-term care than other for-profit homes based on 2 widely used quality measures and were associated with higher total per-beneficiary Medicare costs.
