Effect of hospital-SNF referral linkages on rehospitalization

POST-ACUTE CARE SERVICES AFTER MAJOR ABDOMINAL CANCER SURGERY IN RURAL POPULATIONS: GUIDANCE INTO FUTURE INTERVENTION

INTRODUCTION

Post-Acute Care Services (PACS) are a costly and growing disposition. Yet, little is known about PACS patterns following major cancer surgery, particularly among rural populations given their complex payor mix, medical, and social determinants of health. This study aims to robustly examine the within rural population factors associated with PACS after major abdominal surgery.

METHODS

Hospitalizations of rural patients who underwent major abdominal cancer surgery were identified in the 2016-2021 National Inpatient Sample. Patient- and hospital-level factors were compared by patterns of PACS utilization. Adjusting for these factors, multivariable logistic regression analyses were performed to identify predictors of PACS.

RESULTS

Nearly half of the 35,570 hospitalizations among rural patients received PACS. Medicare and Medicaid accounted for nearly 70% of the payors' mix. Longer length of stay (LOS) was associated with increased likelihood of PACS (p<0.0001), as was every one-day increase in LOS (HHC: aOR,1.09, p<0.0001, transfers: aOR,1.15, p<0.0001). Significant drivers of PACS were older age (vs.<65 years, aOR,1.47, p<0.0001), Medicare insurance (vs. Private, aOR,1.77, p<0.0001), and Medicaid insurance (vs. private, aOR,1.23, p=0.0445). In contrast, non-white race (vs. white, aOR,0.81, p=0.0132) and no insurance (vs. private aOR,0.63, p=0.0011) were associated with fewer PACS.

CONCLUSIONS

Nearly half of rural patients received PACS after major abdominal cancer surgery. PACS were largely driven by older age, Medicare or Medicaid insurance, and prolonged LOS. Further work to investigate additional sociodemographic factors influencing PACS would be beneficial for government, payor, and hospital system planning, and will assist in providing high quality care to rural patients.

Implementing INTERACT in Veterans Health Administration Community Living Centers: A pragmatic randomized trial

BACKGROUND

Hospital transfers from VA Community Living Centers (CLCs) are common. The objective of this study was to evaluate the effect of introducing the Intervention to Reduce Acute Care Transfers (INTERACT) program into VA CLCs.

METHODS

Cluster randomized trial involving 16 pair-matched VA CLCs.

INTERVENTIONS

Intervention CLC nursing staff were trained in the use of INTERACT tools designed to identify early signs of a clinical change in condition and improve communication and documentation. One tool was embedded into the VA Electronic Medical Record. Intervention staff were supported by bi-weekly calls over 18 months to reinforce INTERACT tool use.

MEASUREMENTS

The primary outcome for intent-to-treat analyses was the rate of all-cause hospitalizations per 1000 person days. Secondary outcomes, assessed through structured record reviews and algorithms, were intervention CLCs change in 1) potentially inappropriate transfer decisions and 2) potentially preventable transfers. CLC staff implementation and engagement in INTERACT were documented.

RESULTS

Only five of the eight intervention CLCs substantially engaged in the intervention. Using a negative-binomial regression with random effects, adjusting for month, intervention, and the interaction of time and the intervention, we observed no statistically significant difference between intervention and control facilities in all-cause hospitalizations. This was confirmed with matched resident-level, as-treated, analyses among residents in the five engaged CLCs and their matched controls. Structured implicit review of intervention CLC's medical records revealed low rates of inappropriate transfer decisions both before and after the intervention.

CONCLUSIONS

Introducing INTERACT into volunteer VA CLCs did not reduce the rates of all-cause hospitalizations. In both the pre- and post-intervention periods, all-cause hospitalization rates were relatively higher, and inappropriate transfers lower in VA CLCs than commonly observed in community NHs. Low rates of potentially inappropriate transfers and higher nurse and physician staffing in CLCs may explain why INTERACT was not implemented as fully as planned.

Bundled payments lead to quality improvements in hospitals' skilled nursing facility referral networks

OBJECTIVES

To assess whether hospitals participating in Medicare's Bundled Payments for Care Improvement (BPCI) program for joint replacement changed their referral patterns to favor higher-quality skilled nursing facilities (SNFs).

STUDY DESIGN

Retrospective observational study using 2009-2015 inpatient and outpatient claims from a 20% sample of Medicare beneficiaries undergoing joint replacement in US hospitals (N = 146,074) linked with data from Medicare's BPCI program and Nursing Home Compare.

METHODS

We ran fixed effect regression models regressing BPCI participation on hospital-SNF referral patterns (number of SNF discharges, number of SNF partners, and SNF referral concentration) and SNF quality (facility inspection survey rating, patient outcome rating, staffing rating, and registered nurse staffing rating).

RESULTS

We found that BPCI participation was associated with a decrease in the number of SNF referrals and no significant change in the number of SNF partners or concentration of SNF partners. BPCI participation was associated with discharge to SNFs with a higher patient outcome rating by 0.04 stars (95% CI, 0.04-0.26). BPCI participation was not associated with improvements in discharge to SNFs with a higher facility survey rating (95% CI, -0.03 to 0.11), staffing rating (95% CI, -0.07 to 0.04), or registered nurse staffing rating (95% CI, -0.09 to 0.02).

CONCLUSIONS

BPCI participation was associated with lower volume of SNF referrals and small increases in the quality of SNFs to which patients were discharged, without narrowing hospital-SNF referral networks.

Access to preferred skilled nursing facilities: Transitional care pathways for patients with Alzheimer's disease and related dementias

OBJECTIVE

The study aimed to assess whether individuals with Alzheimer's disease and related dementias (ADRD) experience restricted access to hospitals' high-volume preferred skilled nursing facility (SNF) partners.

DATA SOURCES

The data source includes acute care hospital to SNF transitions identified using 100% Medicare Provider Analysis and Review files, 2017-2019.

STUDY DESIGN

We model and compare the estimated effect of facility "preferredness" on SNF choice for patients with and without ADRD. We use conditional logistic regression with a 1:1 patient sample otherwise matched on demographic and encounter characteristics.

DATA COLLECTION

Our matched sample included 58,190 patients, selected from a total observed population of 3,019,260 Medicare hospitalizations that resulted in an SNF transfer between 2017 and 2019.

PRINCIPAL FINDINGS

Overall, patients with ADRD have a lower probability of being discharged to a preferred SNF (52.0% vs. 54.4%, p < 0.001). Choice model estimation using our matched sample suggests similarly that the marginal effect of preferredness on a patient choosing a proximate SNF is 2.4 percentage points lower for patients with ADRD compared with those without (p < 0.001). The differential effect of preferredness based on ADRD status increases when considering (a) the cumulative effect of multiple SNFs in close geographic proximity, (b) the magnitude of the strength of hospital-SNF relationship, and (c) comparing patients with more versus less advanced ADRD.

CONCLUSIONS

Preferred relationships are significantly predictive of where a patient receives SNF care, but this effect is weaker for patients with ADRD. To the extent that these high-volume relationships are indicative of more targeted transitional care improvements from hospitals, ADRD patients may not be fully benefiting from these investments. Hospital leaders can leverage integrated care relationships to reduce SNFs' perceived need to engage in selection behavior (i.e., enhanced resource sharing and transparency in placement practices). Policy intervention may be needed to address selection behavior and to support hospitals in making systemic improvements that can better benefit all SNF partners (i.e., more robust information sharing systems).

Effects of a Rehabilitation-at-Home Program Compared to Post-acute Skilled Nursing Facility Care on Safety, Readmission, and Community Dwelling Status: A Matched Cohort Analysis

OBJECTIVES

To evaluate the effectiveness and safety of Rehabilitation-at-Home (RaH), which provides high-frequency, multidisciplinary post-acute rehabilitative services in patients' homes.

DESIGN

Comparative effectiveness analysis.

SETTING AND PARTICIPANTS

Medicare Fee-For-Service patients who received RaH in a Center for Medicare and Medicaid Innovation Center Demonstration during 2016-2017 (N=173) or who received Medicare Skilled Nursing Facility (SNF) care in 2016-2017 within the same geographic service area with similar inclusion and exclusion criteria (N=5535).

METHODS

We propensity-matched RaH participants to a cohort of SNF patients using clinical and demographic characteristics with exact match on surgical and non-surgical hospitalizations. Outcomes included hospitalization within 30 days of post-acute admission, death within 30 days of post-acute discharge, length of stay, falls, use of antipsychotic medication, and discharge to community.

RESULTS

The majority of RaH participants were older than or equal to 85 years (57.8%) and non-Hispanic white (72.2%) with mean hospital length of stay of 8.1 (SD 7.6) days. In propensity-matched analyses, 10.1% (95% CI: 0.5%, 19.8) and 4.2% (95% CI: 0.1%, 8.5%) fewer RaH participants experienced hospital readmission and death, respectively. RaH participants had, on average, 2.8 fewer days (95% CI 1.4, 4.3) of post-acute care; 11.4% (95% CI: 5.2%, 17.7%) fewer RaH participants experienced fall; and 25.8% (95% CI: 17.8%, 33.9%) more were discharged to the community. Use of antipsychotic medications was no different.

CONCLUSIONS AND IMPLICATIONS

RaH is a promising alternative to delivering SNF-level post-acute RaH. The program seems to be safe, readmissions are lower, and transition back to the community is improved.

The Impact of Nurse Practitioner Care and Accountable Care Organization Assignment on Skilled Nursing Services and Hospital Readmissions

BACKGROUND

Accountable care organizations (ACOs) and the employment of nurse practitioners (NP) in place of physicians are strategies that aim to reduce the cost and improve the quality of routine care delivered in skilled nursing facilities (SNF). The recent expansion of ACOs and nurse practitioners into SNF settings in the United States may be associated with improved health outcomes for patients.

OBJECTIVES

To determine the relationship between ACO attribution and NP care delivery during SNF visits and the relationship between NP care delivery during SNF visits and unplanned hospital readmissions.

METHODS

We obtained a sample of 527,329 fee-for-service Medicare beneficiaries with 1 or more SNF stays between 2012 and 2017. We used logistic regression to measure the association between patient ACO attribution and evaluation and management care delivered by NPs in addition to the relationship between evaluation and management services delivered by NPs and hospital readmissions.

RESULTS

ACO beneficiaries were 1.26% points more likely to receive 1 or more E&M services delivered by an NP during their SNF visits [Marginal Effect (ME): 0.0126; 95% CI: (0.009, 0.0160)]. ACO-attributed beneficiaries receiving most of their E&M services from NPs during their SNF visits were at a lower risk of readmission than ACO-attributed beneficiaries receiving no NP E&M care (5.9% vs. 7.1%; P <0.001).

CONCLUSIONS

Greater participation by the NPs in care delivery in SNFs was associated with a reduced risk of patient readmission to hospitals. ACOs attributed beneficiaries were more likely to obtain the benefits of greater nurse practitioner involvement in their care.

Quality of Nursing Homes Among ADRD Residents Newly Admitted From the Community: Does Race Matter?

OBJECTIVE

To examine racial differences in admissions to high-quality nursing homes (NHs) among residents with Alzheimer disease and related dementias (ADRD), and whether such racial differences can be influenced by dementia-related state Medicaid add-on policies.

DESIGN

Retrospective cross-sectional study.

SETTING AND PARTICIPANTS

The study included 786,096 Medicare beneficiaries with ADRD newly admitted from the community to NHs between January 1, 2011 and December 31, 2017.

METHODS

2010-2017 Minimum Data Set 3.0, Medicare Beneficiary Summary File, Medicare Provider Analysis and Review, and Nursing Home Compare data were linked. For each individual, we constructed a "choice" set of NHs based on the distance between the NH and an individual residential zip code. McFadden's choice models were estimated to examine the relationship between admission into a high-quality (4- or 5-star) NH and individual characteristics, specifically race, and state Medicaid dementia-related add-on policies.

RESULTS

Among the identified residents, 89% were White, and 11% were Black. Overall, 50% of White and 35% of Black individuals were admitted to high-quality NHs. Black individuals were more likely to be Medicare-Medicaid dually eligible. Results from McFadden's model suggested that Black individuals were less likely to be admitted to a high-quality NH than White individuals (OR = 0.615, P < .01), and such differences were partially explained by some individual characteristics. Furthermore, we found that the racial difference was reduced in states with dementia-related add-on policies, compared with states without these policies (OR = 1.16, P < .01).

CONCLUSIONS AND IMPLICATIONS

Black individuals with ADRD were less likely to be admitted to high-quality NHs than White individuals. Such difference was partially related to individuals' health conditions, social-economic status, and state Medicaid add-on policies. Policies to reduce barriers to high-quality NHs among Black individuals are necessary to mitigate health inequity in this vulnerable population.

Effects of Skilled Nursing Facility Partnerships on Outcomes Following Total Joint Arthroplasty

INTRODUCTION

Post-total joint arthroplasty (TJA) discharge to a skilled nursing facility (SNF) is associated with higher costs and more complications than home discharge; however, some patients still require postoperative SNF care. To improve outcomes for patients requiring postoperative SNF care, this article analyzed the effect of SNF-surgeon partnerships on TJA postoperative costs and patient outcomes.

METHODS

This was a retrospective study of primary TJA patients who were part of Medicare's Comprehensive Care for Joint Replacement (CJR) pilot program at our urban, academic medical center. We identified all patients discharged to SNF and designated SNFs as "preferred" if they maintained a partnership with our surgical team. SNF costs, total 90-day postoperative costs, average length of stay in SNF, 90-day readmission rates, and readmission diagnoses were recorded. Data were compared using Student t-tests. Readmission rates and the presence of a readmission diagnosis were analyzed using z-scores.

RESULTS

Our search identified 189 patients (22.9%) discharged to SNFs, with 128 (67.8%) discharged to preferred and 61 (32.2%) discharged to nonpreferred facilities. Over the 4-year CJR pilot program, SNF costs ($10,981.23 versus $7,343.34; P < 0.005) and overall postdischarge costs ($23,952.52 versus $18,339.26; P = 0.07) were higher for patients discharged to nonpreferred SNFs versus preferred SNFs. Patients discharged to nonpreferred SNFs also had increased length of stay (14.8 versus 10.1 days; P < 0.005) and increased readmission rates (19.7% versus 3.9%; P < 0.005). These differences became more pronounced across the study period.

CONCLUSION

For patients undergoing primary TJA, hospital partnership with SNFs can improve CJR performance by cost reduction and overall outcomes for TJA patients.

Effect of Race/ethnicity, Insurance Status, and Area Deprivation on Hip Fracture Outcomes Among Older Adults in the United States

This retrospective cohort study used electronic health records to explore the effect of race/ethnicity, insurance status, and area deprivation on post-discharge outcomes in older patients undergoing hip fracture surgery between 2015 and 2018 (N = 1,150). Inverse probability of treatment weight-adjusted regression analysis was used to identify the effects of the predictors on outcomes. White patients had higher 90- and 365-day readmission risks than Black patients and higher all-period readmissions than the Other racial/ethnic (Hispanic, Asian, American Indian, and Multicultural) group (p < .000). Black patients had a higher risk of 30- and 90-day readmission than the Other racial/ethnic group (p < .000). Readmission risk across 1-year follow-up was generally higher among patients from less deprived areas than more deprived areas (p < .05). The 90- and 365-day mortality risk was lower for patients from less deprived areas (vs. more deprived areas) and patients with Medicare Advantage (vs. Medicare), respectively (p < .05). Our findings can guide efforts to identify patients for additional post-discharge support. Nevertheless, the findings regarding readmission risks contrast with previous knowledge and thus require more validation studies.

The effects of vertically integrated care on health care use and outcomes in inpatient rehabilitation facilities

OBJECTIVE

To understand the effects of receiving vertically integrated care in inpatient rehabilitation facilities (IRFs) on health care use and outcomes.

DATA SOURCES

Medicare enrollment, claims, and IRF patient assessment data from 2012 to 2014.

STUDY DESIGN

We estimated within-IRF differences in health care use and outcomes between IRF patients admitted from hospitals vertically integrated with the IRF (parent hospital) vs patients admitted from other hospitals. For hospital-based IRFs, the parent hospital was defined as the hospital that owned the IRF and co-located with the IRF. For freestanding IRFs, the parent hospital(s) was defined as the hospital(s) that was in the same health system. We estimated models for freestanding and hospital-based IRFs and for fee-for-service (FFS) and Medicare Advantage (MA) patients. Dependent variables included hospital and IRF length of stay, functional status, discharged to home, and hospital readmissions.

DATA EXTRACTION METHODS

We identified Medicare beneficiaries discharged from a hospital to IRF.

PRINCIPAL FINDINGS

In adjusted models with hospital fixed effects, our results indicate that FFS patients in hospital-based IRFs discharged from the parent hospital had shorter hospital (-0.7 days, 95% CI: -0.9 to -0.6) and IRF (-0.7 days, 95% CI: -0.9 to -0.6) length of stay were less likely to be readmitted (-1.6%, 95% CI: -2.7% to -0.5%) and more likely to be discharged to home care (1.4%, 95% CI: 0.7% to 2.0%), without worse patient clinical outcomes, compared to patients discharged from other hospitals and treated in the same IRFs. We found similar results for MA patients. However, for patients in freestanding IRFs, we found little differences in health care use or patient outcomes between patients discharged from a parent hospital compared to patients from other hospitals.

CONCLUSIONS

Our results indicate that receiving vertically integrated care in hospital-based IRFs shortens institutional length of stay while maintaining or improving health outcomes.

Variability in skilled nursing facility screening and admission processes: Implications for value-based purchasing

BACKGROUND

Hospitalized older adults are increasingly admitted to skilled nursing facilities (SNFs) for posthospital care. However, little is known about how SNFs screen and evaluate potential new admissions. In an era of increasing emphasis on postacute care outcomes, these processes may represent an important target for interventions to improve the value of SNF care.

PURPOSE

The aim of this study was to understand (a) how SNF clinicians evaluate hospitalized older adults and make decisions to admit patients to an SNF and (b) the limitations and benefits of current practices in the context of value-based payment reforms.

METHODS

We used semistructured interviews to understand the perspective of 18 clinicians at three unique SNFs-including physicians, nurses, therapists, and liaisons. All transcripts were analyzed using a general inductive theme-based approach.

RESULTS

We found that the screening and admission processes varied by SNF and that variability was influenced by three key external pressures: (a) inconsistent and inadequate transfer of medical documentation, (b) lack of understanding among hospital staff of SNF processes and capabilities, and (c) hospital payment models that encouraged hospitals to discharge patients rapidly. Responses to these pressures varied across SNFs. For example, screening and evaluation processes to respond to these pressures included gaining access to electronic medical records, providing inpatient physician consultations prior to SNF acceptance, and turning away more complex patients for those perceived to be more straightforward rehabilitation patients.

CONCLUSIONS

We found facility behavior was driven by internal and external factors with implications for equitable access to care in the era of value-based purchasing.

PRACTICE IMPLICATIONS

SNFs can most effectively respond to these pressures by increasing their agency within hospital-SNF relationships and prioritizing more careful patient screening to match patient needs and facility capabilities.

Postacute care outcomes in home health or skilled nursing facilities in patients with a diagnosis of dementia

OBJECTIVE

To compare the outcomes of postacute care between home health (HH) and skilled nursing facilities (SNFs) following hospitalization among Medicare beneficiaries with a diagnosis of dementia.

DATA SOURCES

100% MedPAR data, Minimum Data Set, and Outcome and Assessment Information Set assessment data from January 1, 2015 to December 31, 2016.

STUDY DESIGN

Retrospective cohort analysis using an instrumental variable design to compare outcomes (30-day readmission and mortality, 100-day mortality) of HH versus SNF following acute hospitalization. We used the differential distance between patients' home and the closest HH agency and SNF to instrument for nonrandom allocation of patients.

DATA COLLECTION/EXTRACTION METHODS

We identified hospital discharges followed by SNF and HH stays for Medicare fee-for-service beneficiaries with dementia. We excluded beneficiaries younger than age 65, admitted to the hospital from a nursing home, or enrolled in hospice. We identified dementia using validated diagnostic codes with a 3-year look-back.

PRINCIPAL FINDINGS

Our sample included 977,946 beneficiaries with a diagnosis of dementia; 297,732 (30.4%) received HH, while 680,214 (69.6%) went to SNF. Overall, 16.8% were readmitted to the hospital and 6.1% died within 30 days, while 15.4% died within 100 days of hospital discharge. In the instrumental variable analysis, there were no differences in any outcome between the two postacute care settings.

CONCLUSIONS

Medicare beneficiaries with a diagnosis of dementia receiving postacute care in HH or SNF experienced similar rates of readmission and mortality across settings. This finding raises important questions about current postacute care referral patterns, given 7 in 10 patients with a diagnosis of dementia in our sample were discharged to SNF.

Comparing Receipt of Prescribed Post-acute Home Health Care Between Medicare Advantage and Traditional Medicare Beneficiaries: an Observational Study

BACKGROUND

Medicare Advantage (MA) covers more than 1/3rd of all Medicare beneficiaries. MA plans are required to provide the same benefits as Traditional Medicare (TM), but can impose utilization management tools to control costs.

OBJECTIVE

To assess differences between TM and MA enrollees in the probability of receiving prescribed post-acute home health (HH) care and to describe MA plan characteristics associated with HH receipt.

DESIGN

Retrospective cross-sectional analysis of claims data, HH patient assessment data, and MA plan data from 2011 to 2017.

PARTICIPANTS

Medicare beneficiaries aged 66 and older with an incident hospitalization for joint replacement, pneumonia, chronic obstructive pulmonary disease, stroke, urinary tract infection, septicemia, acute renal failure, or congestive heart failure.

MAIN MEASURES

Receipt of prescribed HH as indicated by a HH discharge code and corresponding HH patient assessment within 14 days of hospital discharge.

KEY RESULTS

There were 2,723,245 beneficiaries prescribed HH at discharge (68% TM, 32% MA). About 75% of TM enrollees and 62% of MA enrollees received prescribed post-acute HH. In adjusted analyses, MA enrollees had an -11.7 percentage point (pp) (95% confidence interval (CI): -16.8, -6.5) lower probability of receiving HH compared with TM enrollees. In adjusted analyses, HMO enrollees in plans with cost sharing (- 8.4 pp; 95% CI: - 14.3, - 2.5), referrals (- 3.7 pp; 95% CI: - 6.1, - 1.2), and pre-authorization (- 5.1 pp; 95% CI: - 8.3, - 2.0) were less likely to receive prescribed HH. In adjusted analyses, PPO enrollees in plans with cost sharing were -7.0 pp (95% CI: - 12.7, - 1.4) less likely to receive HH, but there was no difference for those with referrals (1.1 pp; 95% CI, - 1.5, 3.7) or pre-authorization (1.6 pp; 95% CI: - 0.6, - 3.9).

CONCLUSIONS

Among Medicare beneficiaries, MA enrollees were less likely to receive prescribed post-acute HH compared with TM. As enrollment in MA continues to grow, it is important to examine how differences in utilization relate to outcomes.

Strategy and risk sharing in hospital-postacute care integration

ISSUE/TREND

Postacute care has been identified as a primary area for cost containment. The continued shift of payment structures from volume to value has often put hospitals at the forefront of addressing postacute care cost containment. However, hospitals continue to struggle with models to manage patients in postacute care institutions, such as skilled nursing facilities or in home health agencies. Recent research has identified postacute care network development as one mechanism to improve outcomes for patients sent to postacute care providers. Many hospitals, though, have not utilized this strategy for fear of not adhering to Centers for Medicare & Medicaid Services requirements that patients are given choice when discharged to postacute care.

MANAGERIAL APPROACH

A hospital's approach to postacute care integration will be dictated by environmental uncertainty and the level of embeddedness hospitals have with potential postacute care partners. Hospitals, though, must also consider how and when to extend shared savings to postacute care partners, which will be based on the complexity of the risk-sharing calculation, the ability to maintain network flexibility, and the potential benefits of preserving competition and innovation among the network members. For hospital leaders, postacute care network development should include a robust and transparent data management process, start with an embedded network that maintains network design flexibility, and include a care management approach that includes patient-level coordination.

CONCLUSION

The design of care management models could benefit from elevating the role of postacute care providers in the current array of risk-based payment models, and these providers should consider developing deeper relationships with select postacute care providers to achieve cost containment.

Integration Activities Between Hospitals and Skilled Nursing Facilities: A National Survey

OBJECTIVES

Increasing recognition of the adverse events older adults experience in post-acute care in skilled nursing facilities (SNFs) has led to multiple efforts to improve care integration between hospitals and SNFs. We sought to measure current care integration activities between hospitals and SNFs.

DESIGN

Cross-sectional survey.

SETTING AND PARTICIPANTS

A total of 500 randomly selected Medicare-certified SNFs in the United States in 2019. The survey inquired about 12 care integration activities with the 2 highest volume referring hospitals for each SNF.

METHODS

We collapsed survey responses into 5 categories of integration based on high correlations between the individual measures. These were: (1) formal integration (co-location or co-ownership); (2) informal integration (eg, formal affiliation, participation in SNF collaborative, shared pay for performance, or clinical leadership meetings between hospital and SNF); (3) shared quality/safety activities (eg, initiatives to improve medication safety or reduce hospital admission); (4) shared care coordinators; and/or (5) shared supervising clinicians. We then conducted multivariate regressions to examine associations between different care integration activities and hospital/SNF characteristics.

RESULTS

Our overall response rate was 53.0%, including 265 SNFs that represented 487 SNF-hospital pairs. Informal integration was most common (in 53.3% of pairs), whereas shared clinicians (43.0%), care coordinators (36.5%), shared quality/safety activities (35.1%), and formal integration (7.4%) were present in a minority. Hospital-SNF pairs had lower odds of being formally integrated if the SNF was for-profit compared with not-for-profit [odds ratio (OR) 0.11, 95% confidence interval (CI) 0.03-0.42, adjusted P = .04)] and higher odds of sharing quality improvement activities in metropolitan rather than rural areas (OR 4.06, 95% CI 1.80-9.17, adjusted P = .02) and in the Midwest compared with West (OR 2.95, 95% CI 1.44-6.06, adjusted P = .049).

CONCLUSIONS AND IMPLICATIONS

These findings raise important questions about what is driving variability in hospital-SNF integration activities, and which activities may be most effective for improving transitional care outcomes.

The Effects of Accountable Care Organizations Forming Preferred Skilled Nursing Facility Networks on Market Share, Patient Composition, and Outcomes

BACKGROUND

Through participation in payment reforms such as bundled payment and accountable care organizations (ACOs), hospitals are increasingly financially responsible for health care use and adverse health events occurring after hospital discharge. To improve management and coordination of postdischarge care, ACO hospitals are establishing a closer relationship with skilled nursing facilities (SNFs) through the formation of preferred SNF networks.

RESEARCH DESIGN

We evaluated the effects of preferred SNF network formation on care patterns and outcomes. We included 10 ACOs that established preferred SNF networks between 2014 and 2015 in the sample. We first investigated whether hospitals "steer" patients to preferred SNFs by examining the percentage of patients sent to preferred SNFs within each hospital before and after network formation. We then used a difference-in-difference model with SNF fixed effects to evaluate the changes in patient composition and outcomes of preferred SNF patients from ACO hospitals after network formation relative to patients from other hospitals.

RESULTS

We found that preferred network formation was not associated with higher market share or better outcomes for preferred SNF patients from ACO hospitals. However, we found a small increase in the average number of Elixhauser comorbidities for patients from ACO hospitals after network formation, relative to patients from non-ACO hospitals.

CONCLUSIONS

After preferred SNF network formation, there is some evidence that ACO hospitals sent more complex patients to preferred SNFs, but there was no change in the volume of patients received by these SNFs. Furthermore, preferred network formation was not associated with improvement in patient outcomes.

Higher hospital referral concentration associated with lower-risk patients in skilled nursing facilities

OBJECTIVE

To examine whether stronger referral relationships between hospitals and skilled nursing facilities (SNF) are associated with lower-risk patients being admitted to SNF.

DATA SOURCES/COLLECTION

We used MedPAR data to estimate referral relationship strength and nursing home survey data (OSCAR and CASPER) to determine the risk of patient admissions at nearly 14 000 SNFs from 2008 to 2014.

STUDY DESIGN

We examined the association of hospital referral concentration with the percentage of higher-risk patients admitted to non-hospital-based (freestanding) SNFs using an instrumental variables approach. We used the distance between patients and SNFs and hospitals and SNFs as the instrument.

DATA COLLECTION/EXTRACTION METHODS

We used previously collected MedPAR and OSCAR/CASPER survey data.

PRINCIPAL FINDINGS

We find greater observed referral concentration among freestanding SNFs is associated with lower percentages of patients with pressure sores (coefficient, -2.64; 95% CI, [-2.82 to -2.46]), catheters (-0.55; [-0.74 to -0.36]), and physical restraints (-0.16; [-0.29 to -0.03]) at admission to a skilled nursing facility.

CONCLUSIONS

We find evidence that freestanding SNFs with stronger hospital referral relationships may be admitting less risky patients, possibly contributing to disparities across SNFs.

The association of vertically integrated care with health care use and outcomes

OBJECTIVE

To determine whether vertically integrated hospital and skilled nursing facility (SNF) care is associated with more efficient use of postdischarge care and better outcomes.

DATA SOURCES

Medicare provider, beneficiary, and claims data from 2012 to 2014.

STUDY DESIGN

We compared facility characteristics, quality of care, and health care use for hospital-based SNFs and "virtually integrated" SNFs (defined as freestanding SNFs with close referral relationships with a single hospital) relative to nonintegrated freestanding SNFs. Among patients admitted to integrated SNFs, we estimated differences in health care use and outcomes for patients originating from the parent hospital (ie, receiving vertically integrated care) versus other hospitals using linear regressions that included SNF fixed effects. We estimated bounds for our main estimates that incorporated potential omitted variables bias.

DATA EXTRACTION METHODS

We identified hospital-based SNFs based on provider data. We defined virtually integrated SNFs based on patient flows between hospitals and SNFs. We identified SNF episodes, preceding hospital stays, patient characteristics, health care use, and patient outcomes using Medicare data.

PRINCIPAL FINDINGS

Consistent with prior research, integrated SNFs performed better on quality measures and health care use relative to nonintegrated SNFs (eg, hospital-based SNFs had 11-day shorter stays compared with nonintegrated SNFs adjusting for patient characteristics, P < .001). Stroke patients admitted to hospital-based SNFs from the parent hospital had shorter preceding hospital stays (adjusted difference: -1.2 days, P = .001) and shorter initial SNF stays (adjusted difference: -2.7 days, P = .049); estimates were attenuated but still robust accounting for potential omitted variables bias. For stroke patients, associations between vertically integrated care and other outcomes were either statistically insignificant or not robust to accounting for potential omitted variables bias.

CONCLUSIONS

Vertically integrated hospital and SNF care was associated with shorter hospital and SNF stays. However, there were few beneficial associations with other outcomes, suggesting limited coordination benefits from vertical integration.

Impact of the Iranian Health Sector Evolution Plan on Rehospitalization: An Analysis of 158000 Hospitalizations

Background:

In May 2014, Iran launched the most far-reaching reform for the health sector, so-called Health Sector Evolution Plan (HSEP), since introduction of the primary health care network, with a systematic plan to bring about Universal Health Coverage. We aimed to analyze the time to first all-caused rehospitalization and all-caused 30-day readmission rate in the biggest referral hospital of Northwest of Iran before and after the reform.

Methods:

We retrospectively analyzed discharge data for all hospitalization occurred in the six-year period of 2011–2017. The primary endpoints were readmission-free survival, and overall 30-day readmission rate. Using multivariate cox proportional hazards regression and logistic regression, we assessed between-period differences for readmission-free survival time and overall 30-day rehospitalization, respectively.

Results:

Overall, 157969 admissions were included. After adjusting for available confounders including age; sex; ward of admission; length of stay; and admission in first/second half of year, the risk of being readmitted within 30 days after the reform was significantly higher (worse) compared to pre-reform hospitalization (odd ratio 1.22, P<0.001, 95% CI, 1.15–1.30). Adjusting for the same covariates, after-reform period also was slightly significantly associated with decreased (deteriorated) readmission-free time compared with pre-HSEP period (HR 1.06, P=0.005, 95% CI 1.01–1.11).

Conclusion:

HSEP seems insufficient to improve neither readmission rate, nor readmission-free time. It is advisable some complementary strategies to be incorporated in the HSEP, such as continuity of care promotion, self-care enhancement, effective information flow, and post-discharge follow up programs.

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.

Readmission Reduction Strategies for Patients Discharged to Skilled Nursing Facilities: A Case Study From 2 Hospital Systems in 1 City

BACKGROUND

Some hospitals seek integration with skilled nursing facilities (SNFs) to reduce readmissions while others focus more on patients discharged home.

PURPOSE

Our objective was to understand different approaches for readmission reduction for patients discharged to SNFs based on contrasting strategies from 2 competing hospital systems.

METHODS

Employing a case study methodology, we compared 1 hospital system that integrated with SNFs to a competing system that did not. We compared interview data from clinical and administrative staff and publicly reported rehospitalization rate changes from the 2 systems.

RESULTS

Analysis of integrating hospital system interviews noted providing patients detailed discharge information and educating SNF staff regarding care protocols. Integrated hospital system all-cause readmission rates declined by nearly 1 percentage point more than the nonintegrated hospital system (coefficient, -0.008; 95% confidence interval, -0.003 to -0.012) between 2014 and 2017.

CONCLUSION

As hospitals explore care transition improvements to SNFs, developing more embedded relationships highlights one approach to improve value.

Impact of Self-Care and Mobility on One or More Post-Acute Care Transitions

Objective: To investigate the association between functional status and post-acute care (PAC) transition(s). Methods: Secondary analysis of 2013-2014 Medicare data for individuals aged ≥66 years with stroke, lower extremity joint replacements, and hip/femur fracture discharged to one of three PAC settings (inpatient rehabilitation facilities, skilled nursing facilities, and home health agencies). Functional scores were co-calibrated into a 0-100 scale across settings. Multilevel logistic regression was used to test the partition of variance (%) and the probability of PAC transition attributed to the functional score in the initial PAC setting. Results: Patients discharged to inpatient rehabilitation facilities with higher function were less likely to use additional PAC. Function level in an inpatient rehabilitation facility explained more of the variance in PAC transitions than function level while in a skilled nursing facility. Discussion: The function level affected PAC transitions more for those discharged to an inpatient rehabilitation facility than to a skilled nursing facility.

Trends In Hospitals And Skilled Nursing Facilities Sharing Medical Providers, 2008-16

Hospitals and skilled nursing facilities (SNFs) face increasing pressure to improve care coordination and reduce unnecessary readmissions. One strategy to accomplish this is to share physicians and advanced practice clinicians, so that the same providers see patients in both settings. Using 2008-16 Medicare claims, we found that as SNFs moved increasingly toward using SNF specialists, there was a steady decline in the number of facilities sharing medical providers and in the proportion of SNF primary care delivered by provider practices with both hospital and SNF clinicians (hospital-SNF practices). In SNF fixed effects analyses, we found that SNFs that increased primary care visits by hospital-SNF practices had slightly fewer readmissions, shorter lengths-of-stay, and increased successful community discharges. These findings suggest that SNFs that share medical providers with hospitals may see some benefit from that linkage, although the magnitude of the benefit may be small.

Postacute Management of Older Adults Suffering an Osteoporotic Hip Fracture: A Consensus Statement From the International Geriatric Fracture Society

BACKGROUND

The majority of patients require postacute care (PAC) after a hip fracture. Despite its importance, there is no established consensus regarding the standards of care provided to hip fracture patients in PAC facilities.

METHODOLOGY

A writing group was created by professionals from the International Geriatric Fracture Society (IGFS) with representation from other organizations. The focus of the statements included in this article is toward PAC providers located in nursing facilities. Contributions were integrated in a single document that underwent several reviews by each author and then underwent a final review by the lead and senior authors. After this process was completed, the document was appraised by reviewers from IGFS.

RESULTS/CONCLUSION

A total of 15 statements were crafted. These statements summarize the best available evidence and is intended to help PAC facilities managing older adults with hip fractures more efficiently, aiming toward overall better outcomes in the areas of function, quality of life, and with less complications that could interfere with their optimal recovery.

Variability in Transitional Care Outcomes Across Hospitals Discharging Veterans to Skilled Nursing Facilities

BACKGROUND

The period after transition from hospital to skilled nursing facility (SNF) is high-risk, but variability in outcomes related to transitions across hospitals is not well-known.

OBJECTIVES

Evaluate variability in transitional care outcomes across Veterans Health Administration (VHA) and non-VHA hospitals for Veterans, and identify characteristics of high-performing and low-performing hospitals.

RESEARCH DESIGN

Retrospective observational study using the 2012-2014 Residential History File, which concatenates VHA, Medicare, and Medicaid data into longitudinal episodes of care for Veterans.

SUBJECTS

Veterans aged 65 or older who were acutely hospitalized in a VHA or non-VHA hospital and discharged to SNF; 1 transition was randomly selected per patient.

MEASURES

Adverse "transitional care" outcomes were a composite of hospital readmission, emergency department visit, or mortality within 7 days of hospital discharge.

RESULTS

Among the 365,942 Veteran transitions from hospital to SNF across 1310 hospitals, the composite outcome rate ranged from 3.3% to 23.2%. In multivariable analysis adjusting for patient characteristics, hospital discharge diagnosis and SNF category, no single hospital characteristic was significantly associated with the 7-day adverse outcomes in either VHA or non-VHA hospitals. Very few high or low-performing hospitals remained in this category across all 3 years. The increased odds of having a 7-day event due to being treated in a low versus high-performing hospital was similar to the odds carried by having an intensive care unit stay during the index admission.

CONCLUSIONS

While variability in hospital outcomes is significant, unmeasured care processes may play a larger role than currently measured hospital characteristics in explaining outcomes.

"They Don't Trust Us": The Influence of Perceptions of Inadequate Nursing Home Care on Emergency Department Transfers and the Potential Role for Telehealth

In this descriptive, qualitative study, we conducted eight focus groups with diverse informal and formal caregivers to explore their experiences/challenges with nursing home (NH) to emergency department (ED) transfers and whether telehealth might be able to mitigate some of those concerns. Interviews were transcribed and analyzed using a grounded theory approach. Transfers were commonly viewed as being influenced by a perceived lack of trust in NH care/capabilities and driven by four main factors: questioning the quality of NH nurses' assessments, perceptions that physicians were absent from the NH, misunderstandings of the capabilities of NHs and EDs, and perceptions that responses to medical needs were inadequate. Participants believed technology could provide "the power of the visual" permitting virtual assessment for the off-site physician, validation of nursing assessment, "real time" assurance to residents and families, better goals of care discussions with multiple parties in different locations, and family ability to say goodbye.

Changes in Hospital Referral Patterns to Skilled Nursing Facilities Under the Hospital Readmissions Reduction Program

BACKGROUND

The Hospital Readmissions Reduction Program (HRRP) penalizes hospitals for higher-than-expected readmission rates. Almost 20% of Medicare fee-for-service (FFS) patients receive postacute care in skilled nursing facilities (SNFs) after hospitalization. SNF patients have high readmission rates.

OBJECTIVE

The objective of this study was to investigate the association between changes in hospital referral patterns to SNFs and HRRP penalty pressure.

DESIGN

We examined changes in the relationship between penalty pressure and outcomes before versus after HRRP announcement among 2698 hospitals serving 6,936,393 Medicare FFS patients admitted for target conditions: acute myocardial infarction, heart failure, or pneumonia. Hospital-level penalty pressure was the expected penalty rate in the first year of the HRRP multiplied by Medicare discharge share.

OUTCOMES

Informal integration measured by the percentage of referrals to hospitals' most referred SNF; formal integration measured by SNF acquisition; readmission-based quality index of the SNFs to which a hospital referred discharged patients; referral rate to any SNF.

RESULTS

Hospitals facing the median level of penalty pressure had modest differential increases of 0.3 percentage points in the proportion of referrals to the most referred SNF and a 0.006 SD increase in the average quality index of SNFs referred to. There were no statistically significant differential increases in formal acquisition of SNFs or referral rate to SNF.

CONCLUSIONS

HRRP did not prompt substantial changes in hospital referral patterns to SNFs, although readmissions for patients referred to SNF differentially decreased more than for other patients, warranting investigation of other mechanisms underlying readmissions reduction.

Health information exchange between hospital and skilled nursing facilities not associated with lower readmissions

OBJECTIVE

To assess whether an electronic health record (EHR) portal to enable health information exchange (HIE) between a hospital and three skilled nursing facilities (SNFs) reduced likelihood of patient readmission.

SETTING/DATA

Secondary data; all discharges from a large academic medical center to SNFs between July 2013 and March 2017, combined with portal usage records from SNFs with HIE access.

DESIGN

We use difference-in-differences to determine whether portal implementation reduced likelihood of readmission over time for patients discharged to HIE-enabled SNFs, relative to those discharged to nonenabled facilities. Additional descriptive analyses of audit log data characterize portal use within enabled facilities.

DATA COLLECTION

Encounter-level clinical EHR data were merged with EHR audit log data that captured portal usage in the timeframe associated with a patient transition from hospital to SNF.

PRINCIPAL FINDINGS

Declines in likelihood of 30-day readmission were not significantly different for patients in HIE-enabled vs control SNFs (diff-in-diff = 0.022; P = .431). We observe similar null effects with shorter readmission windows. The portal was used for 46 percent of discharges, with significant usage pattern variation within/across facilities.

CONCLUSIONS

Implementation of a hospital-SNF EHR portal did not reduce readmissions from enabled SNFs. Emergent HIE use cases need to be better defined and leveraged for design and implementation that generates value in the context of postacute transitions.

Post-acute care referral in United States of America: a multiregional study of factors associated with referral destination in a cohort of patients with coronary artery bypass graft or valve replacement

Background

The use of post-acute care (PAC) for cardiovascular conditions is highly variable across geographical regions. Although PAC benefits include lower readmission rates, better clinical outcomes, and lower mortality, referral patterns vary widely, raising concerns about substandard care and inflated costs. The objective of this study is to identify factors associated with PAC referral decisions at acute care discharge.

Methods

This study is a retrospective Electronic Health Records (EHR) based review of a cohort of patients with coronary artery bypass graft (CABG) and valve replacement (VR). EHR records were extracted from the Cerner Health-Facts Data warehouse and covered 49 hospitals in the United States of America (U.S.) from January 2010 to December 2015. Multinomial logistic regression was used to identify associations of 29 variables comprising patient characteristics, hospital profiles, and patient conditions at discharge.

Results

The cohort had 14,224 patients with mean age 63.5 years, with 10,234 (71.9%) male and 11,946 (84%) Caucasian, with 5827 (40.96%) being discharged to home without additional care (Home), 5226 (36.74%) to home health care (HHC), 1721 (12.10%) to skilled nursing facilities (SNF), 1168 (8.22%) to inpatient rehabilitation facilities (IRF), 164 (1.15%) to long term care hospitals (LTCH), and 118 (0.83%) to other locations. Census division, hospital size, teaching hospital status, gender, age, marital status, length of stay, and Charlson comorbidity index were identified as highly significant variables (p- values < 0.001) that influence the PAC referral decision. Overall model accuracy was 62.6%, and multiclass Area Under the Curve (AUC) values were for Home: 0.72; HHC: 0.72; SNF: 0.58; IRF: 0.53; LTCH: 0.52, and others: 0.46.

Conclusions

Census location of the acute care hospital was highly associated with PAC referral practices, as was hospital capacity, with larger hospitals referring patients to PAC at a greater rate than smaller hospitals. Race and gender were also statistically significant, with Asians, Hispanics, and Native Americans being less likely to be referred to PAC compared to Caucasians, and female patients being more likely to be referred than males. Additional analysis indicated that PAC referral practices are also influenced by the mix of PAC services offered in each region.

Medicare's bundled payment model did not change skilled nursing facility discharge patterns

OBJECTIVES

To evaluate whether participation in Medicare's voluntary Bundled Payments for Care Improvement (BPCI) model was associated with changes in discharge referral patterns to skilled nursing facilities (SNFs), specifically number of SNF partners and discharge concentration.

STUDY DESIGN

Retrospective observational study using difference-in-differences analysis.

METHODS

We used Medicare claims data from 2010 to 2015 to identify admissions for lower joint replacement surgery and the following medical conditions: congestive heart failure, renal failure, sepsis, pneumonia, urinary tract and kidney infections, chronic obstructive pulmonary disease, and stroke. We used difference-in-differences analyses to assess changes in discharge patterns among BPCI-participating hospitals compared with matched control hospitals.

RESULTS

Our analytic sample included 3078 acute care hospitals and 14,866 Medicare-certified SNFs in the United States, encompassing more than 47 million hospital discharges. Of these hospitals, 416 participated in BPCI, with the majority selecting into joint replacement episodes (n = 295). BPCI participation was not associated with any change in number of SNF partners (increase by 0.8 SNFs among BPCI hospitals relative to non-BPCI hospitals; 95% CI, -0.2 to 1.9; P = .11) or in discharge concentration (increase in Herfindahl-Hirschman Index of 0.2 among BPCI hospitals relative to non-BPCI hospitals; 95% CI, -68.7 to 69.1; P = .36). Results did not vary across clinical conditions and were robust across duration of BPCI participation and with different comparison groups.

CONCLUSIONS

Hospital participation in BPCI was not associated with changes in the number of SNF partners or in discharge concentration relative to non-BPCI hospitals. More research is needed to understand how hospitals are responding to bundled payment incentives and specific practices that contribute to improvements in cost and quality.

Transitional Care Outcomes in Veterans Receiving Post-Acute Care in a Skilled Nursing Facility

BACKGROUND

As the veteran population ages, more veterans are receiving post-acute care in skilled nursing facilities (SNFs). However, the outcomes of these transitions across Veterans Affairs (VA) and non-VA settings are unclear.

OBJECTIVE

To measure adverse outcomes in veterans transitioning from hospital to SNF in VA and non-VA hospitals and SNFs.

DESIGN

Retrospective observational study using the 2012 to 2014 Residential History File, which concatenates VA, Medicare, and Medicaid data into longitudinal episodes of care for veterans.

SETTING

VA and non-VA hospitals and SNFs in four categories: non-VA SNFs, VA-contracted SNFs, VA Community Living Centers (CLCs), and State Veterans Homes.

PARTICIPANTS

Veterans, aged 65 years or older, who were acutely hospitalized and discharged to an SNF; one transition was randomly selected per patient.

MEASUREMENTS

Adverse "transitional care" outcomes were a composite of hospital readmission, emergency department visit, or mortality within 7 days of hospital discharge.

RESULTS

More than four in five veteran transitions (81.7%) occurred entirely outside the VA system. The overall 7-day outcome rate was 10.7% in the 388 339 veterans included. Adverse outcomes were lowest in VA hospital-CLC transitions (7.5%; 95% confidence interval [CI] = 7.1%-7.8%) and highest in non-VA hospital to VA-contracted nursing home transitions (17.5%; 95% CI = 16.0%-18.9%) in unadjusted analysis. In multivariate analyses adjusted for patient and hospital characteristics, VA hospitals had lower adverse outcome rates than non-VA hospitals (odds ratio [OR] = 0.80; 95% CI = 0.74-0.86). In comparison to VA hospital-VA CLC transitions, non-VA hospital to VA-contracted nursing homes (OR = 2.51; 95% CI = 2.09-3.02) and non-VA hospital to CLC (OR = 2.25; 95% CI = 1.81-2.79) had the highest overall adverse outcome rates.

CONCLUSION

Most veteran hospital-SNF transitions occur outside the VA, although adverse transitional care outcomes are lowest inside the VA. These findings raise important questions about the VA's role as a provider and payer of post-acute care in SNFs. J Am Geriatr Soc 67:1820-1826, 2019.

Hospitals Using Bundled Payment Report Reducing Skilled Nursing Facility Use And Improving Care Integration

A goal of Medicare's bundled payment models is to improve quality and control costs after hospital discharge. Little is known about how participating hospitals are focusing their efforts to achieve these objectives, particularly around the use of skilled nursing facilities (SNFs). To understand hospitals' approaches, we conducted semistructured interviews with an executive or administrator in each of twenty-two hospitals and health systems participating in Medicare's Comprehensive Care for Joint Replacement model or its Bundled Payments for Care Improvement initiative for lower extremity joint replacement episodes. We identified two major organizational responses. One principal strategy was to reduce SNF referrals, using risk-stratification tools, patient education, home care supports, and linkages with home health agencies to facilitate discharges to home. Another was to enhance integration with SNFs: fifteen hospitals or health systems in our sample had formed networks of preferred SNFs to exert influence over SNF quality and costs. Common coordination strategies included sharing access to electronic medical records, embedding providers across facilities, hiring dedicated care coordination staff, and creating platforms for data sharing. As hospitals presumably move toward home-based care and more selective SNF referrals, more evidence is needed to understand how these discharge practices affect the quality of care and patient outcomes.

Use of instrumental variables for endogenous treatment at the provider level

Health economists are often interested in the effects of provider-level attributes (e.g., nonprofit status or quality rating) on patient outcomes, but estimation is subject to selection bias due to correlation with other omitted provider-level attributes that also affect patient outcomes. Recently, researchers have attempted to use patient-level instrumental variables, such as differential distance, to solve this problem of a provider-level endogenous treatment variable in settings where patients are nested within providers. However, to satisfy validity assumptions, an instrumental variable for a provider attribute must be at the provider level or a larger unit of aggregation, not at the patient level. A patient-level instrument cannot predict variation in a provider attribute separately from other, potentially unmeasured, provider attributes. In this paper, we explain this misapplication, review the extent of this problem in recent literature, and offer alternative approaches to avoid this misapplication of patient-level instrumental variables.

Productivity growth of skilled nursing facilities in the treatment of post-acute-care-intensive conditions

BACKGROUND

Health care is believed to be suffered from a "cost disease," in which a heavy reliance on labor limits opportunities for efficiencies stemming from technological improvement. Although recent evidence shows that U.S. hospitals have experienced a positive trend of productivity growth, skilled nursing facilities are relatively "low-tech" compared to hospitals, leading some to worry that productivity at skilled nursing facilities will lag behind the rest of the economy.

OBJECTIVE

To assess productivity growth among skilled nursing facilities (SNFs) in the treatment of conditions which frequently involve substantial post-acute care after hospital discharge.

METHODS

We constructed an analytic file with the records of Medicare beneficiaries that were discharged from acute-care hospitals to SNFs with stroke, hip fracture, or lower extremity joint replacement (LEJR) between 2006 and 2014. We populated each record for 90 days starting at the time of SNF admission, detailing for each day the treatment site and all associated costs. We used ordinary least square regression to estimate growth in SNF productivity, measured by the ratio of "high-quality SNF stays" to total treatment costs. The primary definition of a high-quality stay was a stay that ended with the return of the patient to the community within 90 days after SNF admission. We controlled for patient demographics and comorbidities in the regression analyses.

RESULTS

Our sample included 1,076,066 patient stays at 14,394 SNFs with LEJR, 315,546 patient stays at 14,154 SNFs with stroke, and 739,608 patient stays at 14,588 SNFs with hip fracture. SNFs improved their productivity in the treatment of patients with LEJR, stroke, and hip fracture by 1.1%, 2.2%, and 2.0% per year, respectively. That pattern was robust to a number of alternative specifications. Regressions on year dummies showed that the productivity first decreased and then increased, with a lowest point in 2011. Over the study period, quality continued to rise, but dominated by higher costs at first. Costs then started to decrease, driving productivity to grow.

CONCLUSION

There has been substantial productivity growth in recent years among SNFs in the U.S. in the treatment of post-acute-care-intensive conditions.

What Characteristics Influence Whether Rural Beneficiaries Receiving Care From Urban Hospitals Return Home for Skilled Nursing Care?

PURPOSE

Skilled nursing care (SNC) provides Medicare beneficiaries short-term rehabilitation from an acute event. The purpose of this study is to assess beneficiary, market, and hospital factors associated with beneficiaries receiving care near home.

METHODS

The population includes Medicare beneficiaries who live in a rural area and received acute care from an urban facility in 2013. "Near home" was defined 3 different ways based on distances from the beneficiary's home to the nearest source of SNC. Results include unadjusted means and odds ratios from logistic regression.

FINDINGS

About 69% of rural beneficiaries receiving acute care in an urban location returned near home for SNC. Beneficiaries returning home were white (odds ratio [OR] black: 0.69; other race: 0.79); male (OR: 1.07); older (OR age 85+ [vs 65-69]: 1.14); farther from SNC (OR: 1.01 per mile); closer to acute care (OR: 0.28, logged miles); and received acute care from hospitals that did not own a skilled nursing facility (owned OR: 0.77) and hospitals with: no swing bed (swing bed OR: 0.47), high case mix (OR: 3.04), and nonprofit status (for-profit OR: 0.85). Results varied somewhat across definitions of "near home."

CONCLUSIONS

Rural Medicare beneficiaries who received acute care far from home were more likely to receive SNC far from home. Because Medicare beneficiaries have the choice of where to receive SNC, policy makers may consider ensuring that new payment models do not incentivize provision of SNC away from home.

Choosing the Best and Scrambling for the Rest: Hospital-Nursing Home Relationships and Admissions to Post-Acute Care

OBJECTIVE

We explored post-Affordable Care Act hospital and skilled nursing facility (SNF) perspectives in discharge and admission practices.

METHOD

Interviews were conducted with 138 administrative personnel in 16 hospitals and 25 SNFs in eight U.S. markets and qualitatively analyzed.

RESULTS

Hospitals may use prior referral rates and patients' geographic proximity to SNFs to guide discharges. SNFs with higher hospital referral rates often use licensed nurses to screen patients to admit more preferred patients. While SNFs with lower hospital referral rates use marketing strategies to increase admissions, these patients are often less preferred due to lower reimbursement or complex care needs.

CONCLUSION

An unintended consequence of increased hospital-SNF integration may be greater disparity. SNFs with high hospital referral rates may admit well-reimbursed or less medically complex patients than SNFs with lower referral rates. Without policy remediation, SNFs with lower referral rates may thus care for more medically complex long-term care patients.

The Impact of Comprehensive Care for Joint Replacement Bundled Payment Program on Care Delivery

BACKGROUND

Comprehensive Care for Joint Replacement (CJR) is a Medicare initiative to test the impact of holding a hospital accountable for services provided during an episode of care for a lower extremity joint arthroplasty on costs and quality. This study examines whether hospital participation in CJR is associated with having programs focused on improving posthospitalization care or reducing costs using a survey of orthopedic surgeons.

METHODS

Seventy-three (of 104) orthopedic surgeon members of the Hip Society, a national professional organization of hip surgeons, completed the survey.

RESULTS

Surgeons practicing in CJR hospitals were more likely to report that their hospital had implemented programs focused on improving posthospitalization care or reducing costs. Surgeons in CJR hospitals were significantly more likely to report that the hospital had a narrow network of skilled nursing facilities to enhance care and limit length of stay in skilled nursing facilities (83% vs 47%, P < .01). Surgeons in CJR hospitals were also more likely to report the hospital provides incentives or some type of gainsharing. There were no statistically significant differences in implementation of having programs to reduce costs or improve care during hospitalization.

CONCLUSION

Participation in CJR is associated with higher utilization of hospital practices aimed at improving postdischarge care and higher utilization of linking surgeon compensation to cost and quality.

Reduction in Hospitals' Readmission Rates: Role of Hospital-Based Skilled Nursing Facilities

Hospital readmission within 30 days of discharge is an important quality measure given that it represents a potentially preventable adverse outcome. Approximately, 20% of Medicare beneficiaries are readmitted within 30 days of discharge. Many strategies such as the hospital readmission reduction program have been proposed and implemented to reduce readmission rates. Prior research has shown that coordination of care could play a significant role in lowering readmissions. Although having a hospital-based skilled nursing facility (HBSNF) in a hospital could help in improving care for patients needing short-term skilled nursing or rehabilitation services, little is known about HBSNFs' association with hospitals' readmission rates. This study seeks to examine the association between HBSNFs and hospitals' readmission rates. Data sources included 2007-2012 American Hospital Association Annual Survey, Area Health Resources Files, the Centers for Medicare and Medicaid Services (CMS) Medicare cost reports, and CMS Hospital Compare. The dependent variables were 30-day risk-adjusted readmission rates for acute myocardial infarction (AMI), congestive heart failure, and pneumonia. The independent variable was the presence of HBSNF in a hospital (1 = yes, 0 = no). Control variables included organizational and market factors that could affect hospitals' readmission rates. Data were analyzed using generalized estimating equation (GEE) models with state and year fixed effects and standard errors corrected for clustering of hospitals over time. Propensity score weights were used to control for potential selection bias of hospitals having a skilled nursing facility (SNF). GEE models showed that the presence of HBSNFs was associated with lower readmission rates for AMI and pneumonia. Moreover, higher SNFs to hospitals ratio in the county were associated with lower readmission rates. These findings can inform policy makers and hospital administrators in evaluating HBSNFs as a potential strategy to lower hospitals' readmission rates.

Lost in Transition: a Qualitative Study of Patients Discharged from Hospital to Skilled Nursing Facility

OBJECTIVE

This research aimed to understand the experiences of patients transitioning from hospitals to skilled nursing facilities (SNFs) by eliciting views from patients and hospital and skilled nursing facility staff.

DESIGN

We conducted semi-structured interviews with hospital and skilled nursing facility staff and skilled nursing facility patients and their family members in an attempt to understand transitions between hospital and SNF. These interviews focused on all aspects of the discharge planning and nursing facility placement processes including who is involved, how decisions are made, patients' experiences, hospital-SNF communication, and the presence of programs to improve the transition process.

PARTICIPANTS

Participants were 138 staff in 16 hospitals and 25 SNFs in 8 markets across the country, and 98 newly admitted, previously community-dwelling SNF patients and/or their family members in five of those markets.

APPROACH

Interviews were qualitatively analyzed to identify overarching themes.

KEY RESULTS

Patients reported they felt rushed in making their SNF decisions, did not feel they were appropriately prepared for the hospital-SNF transition or educated about their post-acute needs, and experienced transitions that felt chaotic, with complications they associated with timing and medications. Hospital and SNF staff expressed similar opinions, stating that transitions were rushed, there were problems with the timing of the discharge, with information transfer and medication reconciliation, and that patients were not appropriately prepared for the transition. Staff at some facilities reported programs designed to address these problems, but the efficacy of these programs is unknown.

CONCLUSIONS

Results indicate problematic transitions stemming from insufficient care coordination and failure to appropriately prepare patients and their family members. Previous research suggests that problematic or hurried transitions from hospital to SNF are associated with medication errors and unnecessary rehospitalizations. Interventions to improve transitions from hospital to SNF that include a focus on patients and families are needed.

Post-acute Transitional Journey: Caring for Orthopedic Surgery Patients in the United States

As the geriatric population in the United States continues to age, there will be an increased demand for total hip and total knee arthroplasties (THAs and TKAs). Older patients tend to have more comorbidities and poorer health, and will require post-acute care (PAC) following discharge. The most utilized PAC facilities following THA and TKA are skilled nursing facilities (SNFs), in-patient rehabilitation facilities (IRFs), and home with home health care (HHC). Coordination of care between hospitals and PACs, including the complete transfer of patient information, continues to be a challenge which impacts the quality of care provided by the PACs. The increased demand of hospital resources and PACs by the geriatric population necessitates an improvement in this transition of care process. This review aims to examine the transition of care process currently utilized in the United States for orthopedic surgery patients, and discuss methods for improvement. Employing these approaches will play a key role in improving patient outcomes, decreasing preventable hospital readmissions, and reducing mortality following THA and TKA. The extensive nature of this topic and the ramification of different types of healthcare systems in different countries were the determinant factors limiting our work.

Do Skilled Nursing Facilities Selected to Participate in Preferred Provider Networks Have Higher Quality and Lower Costs?

OBJECTIVE

To determine whether skilled nursing facilities (SNFs) chosen by health systems to participate in preferred provider networks exhibited differences in quality, costs, and patient outcomes relative to other SNFs after accounting for differences in case mix.

DATA SOURCES

Medicare provider and claims data, 2012 and 2013.

STUDY DESIGN

We compared SNFs included in preferred networks relative to other SNFs in the same market, prior to the establishment of preferred provider networks.

DATA EXTRACTION METHODS

We linked the SNFs in our sample to facility characteristics and quality data. We identified SNF admissions and hospitalizations in claims data and limited the analysis to patients discharged from the hospitals in our sample. We obtained patient characteristics from Medicare summary files and the preceding hospital stay.

PRINCIPAL FINDINGS

Preferred SNFs exhibited better performance across publicly reported quality measures. Patients admitted to preferred SNFs exhibited shorter stays, lower Medicare payments, and lower probability of SNF readmission relative to nonpreferred SNFs.

CONCLUSIONS

Our results imply that health systems selected SNFs with lower resource use and better performance on quality measures. Thus, the trend toward preferred provider networks could have implications for Medicare spending and patient health.

The Effects of Medicare Advantage Contract Concentration on Patients' Nursing Home Outcomes

OBJECTIVE

The Medicare Modernization Act of 2004 allowed Medicare Advantage (MA) contracts to form provider networks in order to concentrate their patients among preferred providers. We focus on the skilled nursing facility (SNF) industry to assess patients' health when treating SNFs concentrate more patients from the same MA contract.

DATA SOURCES/STUDY SETTING

We use Medicare Beneficiary Summary File and Health, HEDIS, and the Minimum Data Set for patient attributes and OSCAR, LTCfocus.org, and Nursing Home Compare for SNF attributes. We include 1,069,436 MA enrollees newly admitted to SNF between 2012 and 2014.

STUDY DESIGN

Using a MA contract fixed-effect model, we examine the effect of prevalence of a patient's MA contract in the treating SNF on patient's health outcomes including 180-day survival, 30-day hospital readmission, 30-day home discharge, and nursing home length of stay. We use an Instrumental Variable (IV), the expected share of admissions in a SNF from patient's MA contract calculated using a McFadden choice model.

PRINCIPAL FINDINGS

We find no relationship between SNF contract concentration and patients' outcomes after applying the IV.

CONCLUSIONS

While MA plans appear to steer patients to specific SNFs, we do not observe significant returns to patient outcomes related to concentration.

Implementation of a skilled nursing facility readmission review process

30-day readmissions for patients at skilled nursing facilities (SNF) are common and preventable. We implemented a readmission review process for patients readmitted from two SNFs, involving an electronic review tool and monthly conferences. The electronic review tool captures information related to preventability and factors contributing to readmission. The study included 128 patients, readmitted within 30 days from 1 October 2015 through 1 May 2017, at a tertiary care academic medical centre in Boston, MA, and two partnering SNFs. There was a discrepancy in preventability rating between SNF and hospital reviewers, with 79.7% of cases rated not preventable by the SNF, and 58.6% by the hospital. There was moderate positive correlation between the hospital's and SNFs' preventability ratings (r_s=0.652, p<0.001). In most cases, the SNF reviewers felt that no factors contributed (57.8%), and hospital reviewers felt that issues with end-of-life planning (14.1%) and medical complexity (12.5%) were major factors. Despite the lack of strong correlation between SNF and hospital responses, several cross-continuum quality improvement projects were developed. We found that implementation of a SNF readmission review process employing bidirectional review by SNF and hospital was feasible, and facilitated systems-based improvement in the transition from hospital to postacute care.

Hospital-Skilled Nursing Facility Collaboration: A Mixed-Methods Approach to Understanding the Effect of Linkage Strategies

OBJECTIVE

To characterize the nature and degree of hospitals' efforts to collaborate with skilled nursing facilities (SNFs) and associated patient outcomes.

DATA SOURCES/STUDY SETTING

Qualitative data were collected through 138 interviews with staff in 16 hospitals and 25 SNFs in eight markets across the United States in 2015. Quantitative data include Medicare claims data for the 290,603 patients discharged from those 16 hospitals between 2008 and 2015.

STUDY DESIGN/DATA COLLECTION

Semi-structured interviews with hospital and SNF staff were coded and used to classify hospitals' collaboration efforts with SNFs into high versus low collaboration hospitals, and risk-adjusted, claims-based hospital readmission rates from SNF were compared.

PRINCIPAL FINDINGS

Hospital collaboration efforts were defined as establishing SNF partners, transition management initiatives, and hospital staff visits to SNFs. High collaboration hospitals were more likely to send patients to SNFs (as opposed to home, home with home health, or other PAC settings), sent a higher share of patients to high quality SNFs, and had fewer hospital readmissions from SNF sooner than did low collaboration hospitals.

CONCLUSIONS

Although collaboration with SNF requires significant administrative and clinical time investment, it is associated with positive patient outcomes.

Medicare Advantage enrollees' use of nursing homes: trends and nursing home characteristics

OBJECTIVES

To examine temporal trends in the prevalence of nursing home (NH) patients participating in Medicare Advantage (MA) and to identify the characteristics of both these patients and the NHs that provide care for them.

STUDY DESIGN

Retrospective cohort study.

METHODS

Data sources included the Medicare enrollment file, Minimum Data Set, and facility-level data from the Certification and Survey Provider Enhanced Reporting system. Longitudinal trends of NH use by MA enrollees were examined over the period 2000 to 2013 and logistic regression models were used to identify facility characteristics associated with having a high proportion of MA patients.

RESULTS

The proportion of MA enrollees in NHs more than doubled between 2000 and 2013, increasing 125% during this period. Notable differences in facility characteristics were found between NHs that serve high proportions of MA enrollees and other NHs. High-MA NHs tended to be larger facilities affiliated with chains. These NHs also had better quality indicators, such as higher staffing levels, lower use of antipsychotics, and lower odds of rehospitalization. Additionally, high-MA NHs were more likely to be in counties with higher Medicare managed care penetration and less market concentration.

CONCLUSIONS

MA plans may be selectively contracting with NHs, as evidenced by the larger shares of MA patients who have been placed in facilities with better performance on quality measures. This may reflect MA plans concentrating enrollees in specific facilities and building "networks" of postacute and long-term care providers that provide better and more efficient care.

Accountable Care Organizations and Post-Acute Care: A Focus on Preferred SNF Networks

Due to high magnitude and variation in spending on post-acute care, accountable care organizations (ACOs) are focusing on transforming management of hospital discharge through relationships with preferred skilled nursing facilities (SNFs). Using a mixed-methods design, we examined survey data from 366 respondents to the National Survey of ACOs along with 16 semi-structured interviews with ACOs who performed well on cost and quality measures. Survey data revealed that over half of ACOs had no formal relationship with SNFs; however, the majority of ACO interviewees had formed preferred SNF networks. Common elements of networks included a comprehensive focus on care transitions beginning at hospital admission, embedded ACO staff across settings, solutions to support information sharing, and jointly established care protocols. Misaligned incentives, unclear regulations, and a lack of integrated health records remained challenges, yet preferred networks are beginning to transform the ACO post-acute care landscape.

Comparing post-acute rehabilitation use, length of stay, and outcomes experienced by Medicare fee-for-service and Medicare Advantage beneficiaries with hip fracture in the United States: A secondary analysis of administrative data

BACKGROUND

Medicare Advantage (MA) and Medicare fee-for-service (FFS) plans have different financial incentives. Medicare pays predetermined rates per beneficiary to MA plans for providing care throughout the year, while providers serving FFS patients are reimbursed per utilization event. It is unknown how these incentives affect post-acute care in skilled nursing facilities (SNFs). The objective of this study was to examine differences in rehabilitation service use, length of stay, and outcomes for patients following hip fracture between FFS and MA enrollees.

METHODS AND FINDINGS

This was a retrospective cohort study to examine differences in health service utilization and outcomes between FFS and MA patients in SNFs following hip fracture hospitalization during the period January 1, 2011, to June 30, 2015, and followed up until December 31, 2015. We linked the Master Beneficiary Summary File, Medicare Provider and Analysis Review data, Healthcare Effectiveness Data and Information Set data, the Minimum Data Set, and the American Community Survey. The 6 primary outcomes of interest in this study included 2 process measures and 4 patient-centered outcomes. Process measures included length of stay in the SNF and average rehabilitation therapy minutes (physical and occupational therapy) received per day. Patient-centered outcomes included 30-day hospital readmission, changes in functional status as measured by the 28-point late loss MDS-ADL scale, likelihood of becoming a long-term resident, and successful discharge to the community. Successful discharge from a SNF was defined as being discharged to the community within 100 days of SNF admission and remaining alive in the community without being institutionalized in any acute or post-acute setting for at least 30 days. We analyzed 211,296 FFS and 75,554 MA patients with hip fracture admitted directly to a SNF following an index hospitalization who had not been in a nursing facility or hospital in the preceding year. We used inverse probability of treatment weighting (IPTW) and nursing facility fixed effects regression models to compare treatments and outcomes between MA and FFS patients. MA patients were younger and less cognitively impaired upon SNF admission than FFS patients. After applying IPTW, demographic and clinical characteristics of MA patients were comparable with those of FFS patients. After adjusting for risk factors using IPTW-weighted fixed effects regression models, MA patients spent 5.1 (95% CI -5.4 to -4.8) fewer days in the SNF and received 463 (95% CI to -483.2 to -442.4) fewer minutes of total rehabilitation therapy during the first 40 days following SNF admission, i.e., 12.1 (95% CI -12.7 to -11.4) fewer minutes of rehabilitation therapy per day compared to FFS patients. In addition, MA patients had a 1.2 percentage point (95% CI -1.5 to -1.1) lower 30-day readmission rate, 0.6 percentage point (95% CI -0.8 to -0.3) lower rate of becoming a long-stay resident, and a 3.2 percentage point (95% CI 2.7 to 3.7) higher rate of successful discharge to the community compared to FFS patients. The major limitation of this study was that we only adjusted for observed differences to address selection bias between FFS and MA patients with hip fracture. Therefore, results may not be generalizable to other conditions requiring extensive rehabilitation.

CONCLUSIONS

Compared to FFS patients, MA patients had a shorter course of rehabilitation but were more likely to be discharged to the community successfully and were less likely to experience a 30-day hospital readmission. Longer lengths of stay may not translate into better outcomes in the case of hip fracture patients in SNFs.

Less Intense Postacute Care, Better Outcomes For Enrollees In Medicare Advantage Than Those In Fee-For-Service

Traditional fee-for-service (FFS) Medicare's prospective payment systems for postacute care provide little incentive to coordinate care or control costs. In contrast, Medicare Advantage plans pay for postacute care out of monthly capitated payments and thus have stronger incentives to use it efficiently. We compared the use of postacute care in skilled nursing and inpatient rehabilitation facilities by enrollees in Medicare Advantage and FFS Medicare after hospital discharge for three high-volume conditions: lower extremity joint replacement, stroke, and heart failure. After accounting for differences in patient characteristics at discharge, we found lower intensity of postacute care for Medicare Advantage patients compared to FFS Medicare patients discharged from the same hospital, across all three conditions. Medicare Advantage patients also exhibited better outcomes than their FFS Medicare counterparts, including lower rates of hospital readmission and higher rates of return to the community. These findings suggest that payment reforms such as bundling in FFS Medicare may reduce the intensity of postacute care without adversely affecting patient health.
