Evaluation of post-acute care and one-year outcomes among Medicare beneficiaries with hip fractures: a retrospective cohort study. BMC Med 2023; 21:232. [PMID: 37400841 DOI: 10.1186/s12916-023-02958-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2023] [Accepted: 06/22/2023] [Indexed: 07/05/2023] Open
Abstract
BACKGROUND Post-acute care (PAC) services after hospitalization for hip fracture are typically provided in skilled nursing facilities (SNFs), inpatient rehabilitation facilities (IRFs), or at home via home health care (HHC). Little is known about the clinical course following PAC for hip fracture. We examined the nationwide burden of adverse outcomes by PAC setting in the year following discharge from PAC for hip fracture. METHODS This retrospective cohort included Medicare Fee-for-Service beneficiaries > 65 years who received PAC services in U.S. SNFs, IRFs, or HHC following hip fracture hospitalization between 2012 and 2018. Individuals who had a fall-related injury (FRI) during PAC or received PAC services in multiple settings were excluded. Primary outcomes included FRIs, all-cause hospital readmissions, and death in the year following discharge from PAC. Cumulative incidences and incidence rates for adverse outcomes were reported by PAC setting. Exploratory analyses examined risk ratios and hazard ratios between settings before and after inverse-probability-of-treatment-weighting, which accounted for 43 covariates. RESULTS Among 624,631 participants (SNF, 67.78%; IRF, 16.08%; HHC, 16.15%), the mean (standard deviation) age was 82.70 (8.26) years, 74.96% were female, and 91.30% were non-Hispanic White. Crude incidence rates (95%CLs) per 1000 person-years were highest among individuals receiving SNF care for FRIs (SNF, 123 [121, 123]; IRF, 105 [102, 107]; HHC, 89 [87, 91]), hospital readmission (SNF, 623 [619, 626]; IRF, 538 [532, 544]; HHC, 418 [414, 423]), and death (SNF, 167 [165, 169]; IRF, 47 [46, 49]; HHC, 55 [53, 56]). Overall, rates of adverse outcomes generally remained higher among SNF care recipients after covariate adjustment. However, inferences about the group with greater adverse outcomes differed for FRIs and hospital readmissions based on risk ratio or hazard ratio estimates. CONCLUSIONS In this retrospective cohort study of individuals hospitalized for hip fracture, rates of adverse outcomes in the year following PAC were common, especially among SNF care recipients. Understanding risks and rates of adverse events can inform future efforts to improve outcomes for older adults receiving PAC for hip fracture. Future work should consider calculating risk and rate measures to assess the influence of differential time under observation across PAC groups.

Chatterjee P, Qi M, Werner R. Relative contributions of hospital versus skilled nursing facility quality on patient outcomes. BMJ Qual Saf 2021; 30:195-201. [PMID: 32229627 PMCID: PMC7770560 DOI: 10.1136/bmjqs-2019-010660] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2019] [Revised: 03/04/2020] [Accepted: 03/17/2020] [Indexed: 11/03/2022]
Abstract
BACKGROUND Hospitals and health systems worldwide have adopted value-based payment to improve quality and reduce costs. In the USA, skilled nursing facilities (SNFs) are now financially penalised for higher-than-expected readmission rates. However, the extent to which SNFs contribute to, and should thus be held accountable for, readmission rates is unknown. To compare the relative contributions of hospital and SNF quality on readmission rates while controlling for unobserved patient characteristics. METHODS Retrospective cohort study of Medicare beneficiaries, 2010-2016. Acute care hospitals and SNFs in the USA. Medicare beneficiaries with two hospitalisations followed by SNF admissions, divided into two groups: (1) patients who went to different hospitals but were discharged to the same SNF after both hospitalisations and (2) patients who went to the same hospital but were discharged to different SNFs. Hospital-level and SNF-level quality, using a lagged measure of 30-day risk-standardised readmission rates (RSRRs). Readmission within 30 days of hospital discharge. RESULTS There were 140 583 patients who changed hospitals but not SNFs, and 183 232 who changed SNFs but not hospitals. Patients who went to the lowest-performing hospitals (highest RSRR) had a 0.9% higher likelihood of readmission (p=0.005) compared with patients who went to the highest-performing hospitals (lowest RSRR). In contrast, patients who went to the lowest-performing SNFs had a 2% higher likelihood of readmission (p<0.001) compared with patients to went to the highest-performing SNFs. CONCLUSIONS The association between SNF quality and patient outcomes was larger than the association between hospital quality and patient outcomes among postacute care patients. Holding postacute care providers accountable for their quality may be an effective strategy to improve SNF quality.

Comparing the Contributions of Acute and Postacute Care Facility Characteristics to Outcomes After Hospitalization for Hip Fracture. Med Care 2017; 55:411-420.

Abstract
OBJECTIVE To quantify the contribution of acute versus postacute care factors to survival and functional outcomes after hip fracture. DESIGN, SETTING, AND PARTICIPANTS Retrospective cohort study using Medicare data; subjects included previously ambulatory nursing home residents hospitalized for hip fracture between 2005 and 2009. METHODS We used logistic regression to measure the associations of hospital and nursing home factors with functional and survival outcomes at 30 and 180 days among patients discharged to a nursing facility; we quantified the contribution of hospital versus nursing home factors to outcomes by the ω statistic. RESULTS Among 45,996 hospitalized patients, 1814 (3.9%) died during hospitalization. A total of 42,781 (93%) were discharged alive to a nursing home. Of these, 12,126 (28%) died within 180 days and 20,479 (48%) died or were newly unable to walk within 180 days. Hospital characteristics were not consistently associated with outcomes. Multiple nursing home characteristics predicted 30- and 180-day outcomes, including bed count, chain membership, and performance on selected quality measures. Nursing home factors explained 3 times more variation in the odds of 30-day mortality than did hospital factors [ω, hospital vs. nursing home: 0.32; 95% confidence interval (CI), 0.11, 0.96], 7 times more variation in the odds of 180-day mortality (ω: 0.15; 95% CI, 0.04, 0.61), and 8 times more variation in the odds of 180-day death or new dependence in locomotion (ω: 0.12; 95% CI, 0.05, 0.31). CONCLUSIONS Nursing home factors explain a larger proportion of the variation in clinical outcomes following hip fracture than do hospital factors.

Abstract
OBJECTIVES To determine hospital-level predictors of readmission after hip fracture or potentially related inpatient care processes. DESIGN Retrospective cohort study. SETTING U.S. acute care hospitals. PARTICIPANTS Fee-for-service Medicare beneficiaries who underwent hip fracture surgery between 2007 and 2009 (N = 458,526). MEASUREMENTS Information was obtained on hospital case volumes, teaching status, bed count, nurse staffing, and technological capabilities from Medicare files, and multivariable logistic regression was used to measure the association between these factors and an endpoint of readmission or death at 30 days and between these factors and the timing of surgery. RESULTS Participants treated in the highest-volume hospitals (>175 cases for the study period) had lower odds of readmission or death at 30 days than those treated in low-volume hospitals (≤12; adjusted odds ratio (aOR) = 0.87, 95% confidence interval (CI) = 0.83-0.92, P < .001). Higher nurse skill mix (aOR = 0.88, 95% CI = 0.8-0.96; P = .007) and higher ratio of nurses to beds (aOR = 0.98; 95% CI = 0.97-0.99; P < .001) were also associated with better 30-day outcomes. Greater hospital case volume was associated with lower odds of surgical delay beyond 48 hours. CONCLUSION Better nurse staffing and higher case volumes are associated with lower rates of readmission and mortality after hip fracture surgery; individuals treated at high-volume centers experienced fewer delays in treatment, potentially indicating better inpatient care processes.
