Hospital Variation in Skilled Nursing Facility Use After Coronary Artery Bypass Graft Surgery.

Over 20% of patients are discharged to a skilled nursing facility (SNF) after coronary artery bypass graft surgery, but little is known about specific drivers for postdischarge SNF use. The purpose of this study was to evaluate hospital variation in SNF use and its association with postoperative outcomes after coronary artery bypass graft. A retrospective study design utilizing Medicare Provider Analysis and Review files was used to evaluate SNF use among 70 509 beneficiaries undergoing coronary artery bypass graft, with or without valve procedures, between 2016 and 2018. A total of 17 328 (24.6%) were discharged to a SNF, ranging from 0% to 88% across 871 hospitals. Multilevel logistic regression models identified significant patient-level predictors of discharge to SNF including increasing age, comorbidities, female sex, Black race, dual eligibility, and postoperative complications. After adjusting for patient and hospital factors, 15.6% of the variation in hospital SNF use was attributed to the discharging hospital. Compared with the lower quartile of hospital SNF use, hospitals in the top quartile of SNF use had lower risk-adjusted 1-year mortality (12.5% versus 8.6%, P<0.001) and readmission (59.9% versus 49.8%, P<0.001) rates for patients discharged to a SNF. There is high variability in SNF use among hospitals that is only partially explained by patient characteristics. Hospitals with higher SNF utilization had lower risk-adjusted 1-year mortality and readmission rates for patients discharged to a SNF. More work is needed to better understand underlying provider and hospital-level factors contributing to SNF use variability.

Bundled Payments for Care Improvement and Quality of Care and Outcomes in Heart Failure

The Centers for Medicare & Medicaid Services (CMS) Bundled Payments for Care Improvement (BPCI) program was launched in 2013 with a goal to improve care quality while lowering costs to Medicare. To compare changes in the quality and outcomes of care for patients hospitalized with heart failure according to hospital participation in the BPCI program. This cross-sectional study used a difference-in-difference approach to evaluate the BPCI program in 18 BPCI hospitals vs 211 same-state non-BPCI hospitals for various process-of-care measures and outcomes using American Heart Association Get With The Guidelines-Heart Failure registry and CMS Medicare claims data from November 1, 2008, to August 31, 2018. Data were analyzed from May 2022 to May 2023. Hospital participation in CMS BPCI Model 2 Heart Failure, which paid hospitals in a fee-for-service process and then shared savings or required reimbursement depending on how the total cost of an episode of care compared with a target price. Primary end points included 7 quality-of-care measures. Secondary end points included 9 outcome measures, including in-hospital mortality and hospital-level risk-adjusted 30-day and 90-day all-cause readmission rate and mortality rate. During the study period, 8721 patients were hospitalized in the 23 BPCI hospitals and 94 530 patients were hospitalized in the 224 same-state non-BPCI hospitals. Less than a third of patients (30 723 patients, 29.8%) were 75 years or younger; 54 629 (52.9%) were female, and 48 622 (47.1%) were male. Hospital participation in BPCI Model 2 was not associated with significant differential changes in the odds of various process-of-care measures, except for a decreased odds of evidence-based β-blocker at discharge (adjusted odds ratio [aOR], 0.63; 95% CI, 0.41-0.98; P = .04). Participation in the BPCI was not associated with a significant differential change in the odds of receiving angiotensin-converting enzyme inhibitors/angiotensin receptor blockers or angiotensin receptor-neprilysin inhibitors at discharge, receiving an aldosterone antagonist at discharge, having a cardiac resynchronization therapy (CRT)-defibrillator or CRT pacemaker placed or prescribed at discharge, having implantable cardioverter-defibrillator (ICD) counseling or an ICD placed or prescribed at discharge, heart failure education being provided among eligible patients, or having a follow-up visit within 7 days or less. Participation in the BPCI was associated with a significant decrease in odds of in-hospital mortality (aOR, 0.67; 95% CI, 0.51-0.86; P = .002). Participation was not associated with a significant differential change in hospital-level risk-adjusted 30-day or 90-day all-cause readmission rate and 30-day or 90-day all-cause mortality rate. In this study, hospital participation in the BPCI Model 2 Heart Failure program was not associated with improvement in process-of-care quality measures or 30-day or 90-day risk-adjusted all-cause mortality and readmission rates.

Age-Based Trends in the Outcomes of Percutaneous Left Atrial Appendage Occlusion: Insights from a Real-World Database

The age-based trends in-hospital outcomes in patients with percutaneous left atrial appendage occlusion (LAAO) are unknown. Using the National Readmission Database from 2016 to 2019, patients who underwent LAAO were divided into 2 age groups: 60 to 79 and ≥80 years. The primary objective was to evaluate the age-based trends in the outcomes related to LAAO. The secondary objectives were to evaluate the mean cost and total cumulative cost of readmissions in both age groups in 2019. We identified 58,818 patients who underwent LAAO, of whom 36,964 (63%) were aged 60 to 79 years, and 21,854 (37%) were ≥80 years. The hospital mortality, pericardial complications, acute kidney injury, and in-hospital cardiac arrest did not change over time. The risk-adjusted postoperative stroke and bleeding requiring blood transfusion decreased in patients aged ≥80 years (p trend 0.03 for both outcomes). The length of stay decreased, and early discharge rates increased over time in both the unadjusted and risk-adjusted models in both age groups. The risk-adjusted 90-day readmission rates also decreased in patients aged ≥80 years. The inflation-adjusted cost did not change over time on the unadjusted and adjusted analyses. The total cumulative all-cause 90-readmission cost for both groups in 2019 was $31.7 million. Most outcomes after LAAO either improved or did not change from 2016 to 2019. Hospital mortality has remained <0.5% consistently since 2016. The risk-adjusted postoperative stroke, bleeding, and 90-day readmission rates improved in elderly vulnerable patients aged ≥80 years. The inflation-adjusted cost did not improve despite the decreasing length of stay and improving early discharge rates.

Annual Variation in 30-Day Risk-Adjusted Readmission Rates in U.S. Children's Hospitals.

Reducing pediatric readmissions has become a national priority; however, the use of readmission rates as a quality metric remains controversial. The goal of this study was to examine short-term stability and long-term changes in hospital readmission rates. Data from the Pediatric Health Information System were used to compare annual 30-day risk-adjusted readmission rates (RARRs) in 47 US children's hospitals from 2016 to 2017 (short-term) and 2016 to 2019 (long-term). Pearson correlation coefficients and weighted Cohen's Kappa statistics were used to measure correlation and agreement across years for hospital-level RARRs and performance quartiles. Median (IQR) 30-day RARRs remained stable from 7.7% (7.0-8.3) in 2016 to 7.6% (7.0-8.1) in 2019. Individual hospital RARRs in 2016 were strongly correlated with the same hospital's 2017 rate (R2=0.89 [95% confidence interval (CI) 0.80-0.94]) and moderately correlated with those in 2019 (R2=0.49 [95%CI 0.23-0.68]). Short-term RARRs (2016 vs 2017) were more highly correlated for medical conditions than surgical conditions, but correlations between long-term medical and surgical RARRs (2016 vs 2019) were similar. Agreement between RARRs was higher when comparing short-term changes (0.73 [95%CI 0.59-0.86]) than long-term changes (0.45 [95%CI 0.27-0.63]). From 2016 to 2019, RARRs increased by ≥1% in 7 (15%) hospitals and decreased by ≥1% in 6 (13%) hospitals. Only 7 (15%) hospitals experienced reductions in RARRs over the short and long-term. Hospital-level performance on RARRs remained stable with high agreement over the short-term suggesting stability of readmission measures. There was little evidence of sustained improvement in hospital-level performance over multiple years.

Trends and Outcomes for Percutaneous Coronary Intervention and Coronary Artery Bypass Graft Surgery in New South Wales from 2008 to 2019

Risk profiles are changing for patients who undergo percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG). In Australia, little is known of the nature of these changes in contemporary practice and of the impact on patient outcomes. We identified all CABG (n=40,805) and PCI (n=142,399) procedures in patients aged ≥18 years in New South Wales, Australia, during 2008 to 2019. Between 2008 and 2019, the age- and gender-standardized revascularization rate increased by 20% (from 267/100,000 to 320/100,000 population) for all revascularizations. The increase in revascularization was particularly driven by a 35% increase (from 194/100,000 to 261/100,000) in PCI, whereas the rate of CABG decreased by 20% (from 73/100,000 to 59/100,000). Mean age and the prevalence of co-morbidities (especially diabetes and atrial fibrillation) increased for patients with PCI in more recent years but remained consistently lower than for patients with CABG. CABGs performed in patients presenting with a non-ST-segment-elevation acute coronary syndrome halved from 34.3% to 18.7% during the study period, whereas PCIs in this group decreased from 36.5% to 29.6%. Risk-adjusted in-hospital mortality decreased by 7.5 deaths/1,000 procedures per month for CABG but remained unchanged for PCI. Risk-adjusted readmission rates were consistently higher for CABG than for PCI and did not change significantly over time. In conclusion, we observed a dramatic shift over time from CABG to PCI as the revascularization procedure of choice, with the patient base for PCI extending to older and sicker patients. There was a large decrease in mortality after CABG, whereas mortality after PCI remained unchanged.

Association of Health Professional Shortage Area Hospital Designation With Surgical Outcomes and Expenditures Among Medicare Beneficiaries.

To compare surgical outcomes and expenditures at hospitals located in Health Professional Shortage Areas to nonshortage area designated hospitals among Medicare beneficiaries. More than a quarter of Americans live in federally designated Health Professional Shortage Areas. Although there is growing concern that medical outcomes may be worse, far less is known about hospitals providing surgical care in these areas. Cross-sectional retrospective study from 2014 to 2018 of 842,787 Medicare beneficiary patient admissions to hospitals with and without Health Professional Shortage Area designations for common operations including appendectomy, cholecystectomy, colectomy, and hernia repair. We assessed risk-adjusted outcomes using multivariable logistic regression accounting for patient factors, admission type, and year were compared for each of the 4 operations. Hospital expenditures were price-standardized, risk-adjusted 30-day surgical episode payments. Primary outcome measures included 30-day mortality, hospital readmissions, and 30-day surgical episode payments. Patients (mean age=75.6 years, males=44.4%) undergoing common surgical procedures in shortage area hospitals were less likely to be White (84.6% vs 88.4%, P <0.001) and less likely to have≥2 Elixhauser comorbidities (75.5% vs 78.2%, P <0.001). Patients undergoing surgery at Health Professional Shortage Area hospitals had lower risk-adjusted rates of 30-day mortality (6.05% vs 6.69%, odds ratio=0.90, CI, 0.90-0.91, P <0.001) and readmission (14.99% vs 15.74%, odds ratio=0.94, CI, 0.94-0.95, P <0.001). Medicare expenditures at Health Professional Shortage Area hospitals were also lower than nonshortage designated hospitals ($28,517 vs $29,685, difference= -$1168, P <0.001). Patients presenting to Health Professional Shortage Area hospitals obtain safe care for common surgical procedures without evidence of higher expenditures among Medicare beneficiaries. These findings should be taken into account as current legislative proposals to increase funding for care in these underserved communities are considered.

Skilled Nursing Facility Quality Rating and Surgical Outcomes Following Coronary Artery Bypass Grafting

Centers for Medicare and Medicaid Services created a 5-star quality rating system to evaluate skilled nursing facilities (SNFs). Patient discharge to lower-star quality SNFs has been shown to adversely impact surgical outcomes. Recent data has shown that over 20% of patients are discharged to an SNF after CABG, but the link between SNF quality and CABG outcomes has not been established. The purpose of this study is to evaluate the impact of SNF quality ratings on postoperative outcomes after CABG. Retrospective cohort review of Medicare patients undergoing CABG and discharged to an SNF between the years 2016-2017. Patients were categorized into 3 groups according to the star rating of the SNF with receipt of care after discharge (ie, below average, average, above average). Risk-adjusted 30-day to 1-year outcomes of mortality, readmission, and SNF length of stay were calculated and compared using multivariable logistic regression and Poisson models across SNF quality categories. Of the 73,164 Medicare patients in our sample, 15,522 (21.2%) were discharged to an SNF. Patients in below average SNFs were more likely to be younger, Black, Medicare/Medicaid dual eligible, and have more comorbidities. Compared to above average SNFs, patients discharged to below average SNFs experienced higher risk-adjusted 30-day mortality (2.1% vs 1.6%, P<0.02), readmission (21.6% vs 19.3%, P<0.01) and SNF length of stay (17.3d vs 16.5d, P<0.0001). Within 90-days, below average SNFs experienced higher risk-adjusted readmission rates (31.7% vs 30.0%, P<0.004). Outcomes at 1-year were not statistically significant. Medicare beneficiaries discharged to lower quality SNFs experienced worse postoperative outcomes after CABG. Identifying best practices at high performing SNFs, to potentially implement at low performing facilities, may improve equitable care for patients.

Coronary Artery Bypass Surgery Among Medicare Beneficiaries in Health Professional Shortage Areas.

Health professional shortage areas (HPSAs) were created by the Health Resources and Services Administration to identify communities with a shortage of clinical providers. For medical conditions, these designations are associated with worse outcomes. However, far less is known about patients undergoing high-complexity surgical procedures, such as coronary artery bypass grafting (CABG). The aim was to compare postoperative surgical outcomes of high-complexity surgery in beneficiaries living in HPSA versus non-HPSA designated areas. This study is a retrospective cohort review of Medicare beneficiaries who underwent CABG between 2014 and 2018. The authors compared risk-adjusted 30-day mortality, complication, reoperation, and readmission rates for beneficiaries living in a designated HPSA versus non-HPSA using a multivariable logistic regression model accounting for patient (eg, age, sex, comorbidities, surgery year) and hospital characteristics (eg, patient-to-nurse ratio, teaching status). Patient travel burden was measured based on the time and distance required to travel from the beneficiary's home zip code to the hospital zip code. Of the 370,532 Medicare beneficiaries who underwent CABG, 30,881 (8.3%) lived in a HPSA. Beneficiaries in HPSAs were found to experience comparable 30-day mortality (3.50% vs. 3.65%, P <0.001), complication (32.67% vs. 33.54%, P <0.001), reoperation (1.58% vs. 1.66%, P <0.001), and readmission (14.72% vs. 14.86%, P <0.001) rates. Beneficiaries experienced greater mean travel times (91.2 vs. 64.0 minutes, P <0.001) and mean travel distances (85.0 vs. 59.3 miles, P <0.001). Medicare beneficiaries living in designated HPSA experienced comparable surgical outcomes after CABG surgery but a significantly greater travel burden. The greater travel burden experienced by patients living in designated shortage areas to obtain comparable surgical care for complex procedures demonstrates important tradeoffs between access and quality.

Evaluating the Hospital Standardized Home-Transition Ratios for Cerebral Infarction in Japan: A Retrospective Observational Study from 2016 through 2020.

Discharge to home is considered appropriate as a treatment goal for diseases that often leave disabilities such as cerebral infarction. Previous studies showed differences in risk-adjusted in-hospital mortality and readmission rates; however, studies assessing the rate of hospital-to-home transition are limited. We developed and calculated the hospital standardized home-transition ratio (HSHR) using Japanese administrative claims data from 2016–2020 to measure the quality of in-hospital care for cerebral infarction. Overall, 24,529 inpatients at 35 hospitals were included. All variables used in the analyses were associated with transition to another hospital or facility for inpatients, and evaluation of the HSHR model showed good predictive ability with c-statistics (area under curve, 0.73 standard deviation; 95% confidence interval, 0.72–0.73). All HSHRs of each consecutive year were significantly correlated. HSHRs for cerebral infarction can be calculated using Japanese administrative claims data. It was found that there is a need for support for low HSHR hospitals because hospitals with high/low HSHR were likely to produce the same results in the following year. HSHRs can be used as a new quality indicator of in-hospital care and may contribute to assessing and improving the quality of care.

Looking Outwards and Inwards to Improve Patient Care Quality and Clinical Outcomes in U.S. Hospitals

Keeping a typical U.S. hospital in mind, we draw support from quality management and lean systems theory to empirically test a framework that links variables looking outwards (supplier relationship management), and inwards (internal lean orientation) to patient care quality and two important hospital clinical outcomes—mortality rate and readmission rate. This integrated framework can help U.S. hospitals identify and solve issues—both internal and external, some of which lie outside their current boundaries, with their supply chain partners. Contrary to our expectations, we do not find support for a link between patient care quality and readmission rate; and instead, internal lean orientation is positively associated with the mortality rate for a hospital. We offer plausible explanations and conclude with broader implications of our research for both health care research and practice. KEYWORDS: Supplier relationship management; internal lean orientation; patient care quality; 30-day risk-adjusted mortality rate (RAMR); 30-day risk-adjusted readmission rate (RARR); hospital clinical outcomes

Variation in Condition-Specific Readmission Rates Across US Children's Hospitals.

Despite extensive efforts, overall readmission rates at US children's hospitals have not materially declined over the past decade, raising questions about how to direct future efforts. Using measures of prevalence and performance variation we describe readmission rates by condition and identify priority conditions for future intervention. Retrospective cohort study of 49 US children's hospitals in the Pediatric Health Information System in 2017. Conditions were classified using All Patients Refined Diagnosis Related Groups. 30-day unadjusted and risk-adjusted readmission rates were calculated for each hospital/condition using the Pediatric All Cause Readmission measure. We ranked the highest volume conditions by rate variation (RV, interquartile range divided by the median) for each condition across hospitals. The sample included 811,434 index hospitalizations with 50,196 (6.2%) 30-day readmissions. The RV across hospitals/conditions was between 0 and 2.8 (median=0.7). Common reasons for admission had low RVs across hospitals, for example, bronchiolitis (readmission rate=5.6%, RV=0.4), seizure (readmission rate=6.6%, RV=0.3), and asthma (readmission rate=3.1%, RV=0.4). We identified 33 conditions with high variation in readmission rates across hospitals, which accounted for 18% of all discharges and 11% of all pediatric readmissions. These conditions may serve as candidates for future readmission reduction activities. Many common childhood conditions have little variation in readmission rates across children's hospitals, suggesting limited future improvement opportunities. Conditions with high rate variation may provide opportunities for quality improvement; however, these conditions account for a relatively small share of total discharges suggesting modest potential impacts on national rates.

Is Skilled Nursing Facility Financial Status Related to Readmission Rate Improvement?

We examined whether higher skilled nursing facility (SNF) lagged profitability is associated with a lower 30-day all-cause all-payer risk-adjusted hospital readmission rate. Our aim was to provide insight into whether SNFs with limited financial resources are able to respond to incentives to lower their readmission rates to hospitals. We used data from 2012-2016 to estimate a fixed effects (FE) model with a time trend. Our data included financial data from the Centers for Medicare & Medicaid Services Healthcare Cost Report Information System SNF cost reports, facility characteristics including the all-cause all-payer risk-adjusted unplanned 30-day readmission rate from the LTCFocus (Long-Term Care Focus) project at Brown University, and county-level market variables from the Area Health Resource File. We also examined the relationship for a shorter time frame (2012-2015) after stratifying the sample by system membership or ownership. SNFs with an increase in the lagged operating margin showed a statistically significant, small decrease (<.01 percentage point) in the risk-adjusted readmission rate. The results were robust for different time periods and model specifications. Fixed effects model estimates for SNFs in the highest quartile of percentage of Medicaid patients (≥73.9%) had a lagged operating margin coefficient that is almost four times as large as the coefficient of the FE model with all SNFs. SNFs have an important role in achieving the national priority of reducing hospital readmissions. The study findings suggest that managers of SNFs should not see low profitability as an obstacle to reducing readmission rates, which is good news given the low average profitability of SNFs. Further, reductions in profitability due to penalties incurred from the recently implemented Medicare Skilled Nursing Facility Value-Based Purchasing Program may not limit SNFs' ability to lower hospital readmission rates, at least initially. However, policymakers may need to determine whether additional resources to high Medicaid SNFs can lower readmission rates for these SNFs.

Factors Associated With Disparities in Hospital Readmission Rates Among US Adults Dually Eligible for Medicare and Medicaid

Low-income older adults who are dually eligible (DE) for Medicare and Medicaid often experience worse outcomes following hospitalization. Among other federal policies aimed at improving health for DE patients, Medicare has recently begun reporting disparities in within-hospital readmissions. The degree to which disparities for DE patients are owing to differences in community-level factors or, conversely, are amenable to hospital quality improvement, remains heavily debated. To examine the extent to which within-hospital disparities in 30-day readmission rates for DE patients are ameliorated by state- and community-level factors. In this retrospective cohort study, Centers for Medicare & Medicaid Services (CMS) Disparity Methods were used to calculate within-hospital disparities in 30-day risk-adjusted readmission rates for DE vs non-DE patients in US hospitals participating in Medicare. All analyses were performed in February and March 2019. The study included Medicare patients (aged ≥65 years) hospitalized for acute myocardial infarction (AMI), heart failure (HF), or pneumonia in 2014 to 2017. Within-hospital disparities, as measured by the rate difference (RD) in 30-day readmission between DE vs non-DE patients following admission for AMI, HF, or pneumonia; variance across hospitals; and correlation of hospital RDs with and without adjustment for state Medicaid eligibility policies and community-level factors. The final sample included 475 444 patients admitted for AMI, 898 395 for HF, and 1 214 282 for pneumonia, of whom 13.2%, 17.4%, and 23.0% were DE patients, respectively. Dually eligible patients had higher 30-day readmission rates relative to non-DE patients (RD >0) in 99.0% (AMI), 99.4% (HF), and 97.5% (pneumonia) of US hospitals. Across hospitals, the mean (IQR) RD between DE vs non-DE was 1.00% (0.87%-1.10%) for AMI, 0.82% (0.73%-0.96%) for HF, and 0.53% (0.37%-0.71%) for pneumonia. The mean (IQR) RD after adjustment for community-level factors was 0.87% (0.73%-0.97%) for AMI, 0.67% (0.57%-0.80%) for HF, and 0.42% (0.29%-0.57%) for pneumonia. Relative hospital rankings of corresponding within-hospital disparities before and after community-level adjustment were highly correlated (Pearson coefficient, 0.98). In this cohort study, within-hospital disparities in 30-day readmission for DE patients were modestly associated with differences in state Medicaid policies and community-level factors. This suggests that remaining variation in these disparities should be the focus of hospital efforts to improve the quality of care transitions at discharge for DE patients in efforts to advance equity.

Risk-Adjusted, 30-Day Home Time After Transcatheter Aortic Valve Replacement as a Hospital-Level Performance Metric

BackgroundPatient-centric measures of hospital performance for transcatheter aortic valve replacement (TAVR) are needed. ObjectivesThis study evaluated 30-day, risk-adjusted home time as a hospital performance metric for patients who underwent TAVR. MethodsThis study identified 160,792 Medicare beneficiaries who underwent elective TAVR from 2015 to 2019. Home time was calculated for each patient as the number of days alive and spent outside the hospital, skilled nursing facility (SNF), and long-term acute care facility for 30 days after the TAVR procedure date. Correlations between risk-adjusted, 30-day home time and other metrics (30-day, risk-adjusted readmission rate [RSRR], 30-day, risk-adjusted mortality rate [RSMR], and annual TAVR volume) were estimated using Pearson’s correlation. Meaningful upward or downward reclassification (≥2 quartile ranks) in hospital performance based on quartiles of risk-adjusted, 30-day home time compared with quartiles of other measures were assessed. ResultsMedian risk-adjusted, 30-day home time was 27.4 days (interquartile range [IQR]: 26.3-28.5 days). The largest proportion of days lost from 30-day home time was hospital stay after TAVR and SNF stay. An inverse correlation was observed between hospital-level, risk-adjusted, 30-day home time and 30-day RSRR (r = −0.465; P < 0.001) and 30-day RSMR (r = −0.3996; P < 0.001). The use of the 30-day, risk-adjusted home time was associated with reclassification in hospital performance rank hospitals compared with other metrics (9.1% up-classified, 11.2% down-classified vs RSRR; 9.1% up-classified, 10.3% down-classified vs RSMR; and 20.1% up-classified, 19.3% down-classified vs annual TAVR volume). ConclusionsRisk-adjusted, 30-day home time represents a novel patient-centered performance metric for TAVR hospitals that may provide a complimentary assessment to currently used metrics.

Reducing Readmissions for Chronic Obstructive Pulmonary Disease in Response to the Hospital Readmissions Reduction Program.

Rationale: In August 2013, the Hospital Readmission Reduction Program announced financial penalties on hospitals with higher than expected risk-adjusted 30-day readmission rates for Medicare beneficiaries hospitalized for chronic obstructive pulmonary disease (COPD) exacerbation. In October 2014, penalties were imposed. We hypothesized that penalties would be associated with decreased readmissions after COPD hospitalizations. Objectives: To determine whether the announcement and enactment of financial penalties for COPD were associated with decreases in hospital readmissions for COPD. Methods: We used data from California's Office of Statewide Health Planning and Development to examine unplanned 30-day all-cause and COPD-related readmissions after COPD hospitalization. The preannouncement period was January 2010 to July 2013. The postannouncement period was August 2013 to September 2014. The postenactment period was October 2014 to December 2017. Using interrupted time series, we investigated the immediate change after the intervention (level change) and differences in the preintervention and postintervention trends (slope change). Results: We identified 333,429 index hospitalizations for COPD from 449 California hospitals. Overall, 69% of patients had Medicare insurance. For all-cause readmissions, the level change at announcement was 0.16% (95% confidence interval [CI], -1.07 to 1.38; P = 0.80); the change in slope between preannouncement and postannouncement periods was -0.01% (95% CI, -0.15 to 0.13; P = 0.92). The level change at enactment was 0.29% (95% CI, -1.11 to 1.69; P = 0.68); the change in slope between postannouncement and postenactment was 0.04% (95% CI, -0.10 to 0.18; P = 0.57). For patients with COPD-related readmissions, the level change at the time of the announcement was 0.09% (95% CI, -0.68 to 0.85; P = 0.83); the change in slope was 0.003% (95% CI, -0.08 to 0.09; P = 0.94). The level change at the time of the enactment was 0.22% (95% CI, -0.69 to 1.12; P = 0.64); the change in slope was -0.02% (95% CI, -0.10 to 0.07; P = 0.72). Conclusions: We did not detect decreases in either all-cause or COPD-related readmission rates at either time point. Although this would suggest that the Hospital Readmission Reduction Program penalty was ineffective for COPD, COPD readmissions had decreased at an earlier time point (October 2012) when penalties were announced for conditions other than COPD. Based on this, we believe early, broad interventions decreased readmissions, such that no difference was seen at this later time points despite institution of COPD-specific penalties.

Incomplete Home Health Care Referral After Hospitalization Among Medicare Beneficiaries

ObjectivesPatients who are referred to home health care after an acute care hospitalization may not receive home health care, resulting in incomplete home health referrals. This study examines the prevalence of incomplete referrals to home health, defined as not receiving home health care within 7 days after an initial hospital discharge, and investigates the relationship between home health referral completion and patient outcomes. DesignRetrospective cohort study. Setting and ParticipantsMedicare beneficiaries who are discharged from short-term acute care hospitals between October 2015 and December 2016 with a discharge status code on the hospital claim indicating home health care. MethodsPatient characteristics and outcomes were compared between Medicare beneficiaries with complete and incomplete home health referrals after hospital discharge. The outcomes included mortality, readmission rate, and total spending over a 1-year episode following hospitalization. These outcomes were risk-adjusted using patient demographic, socioeconomic, clinical characteristic, hospital characteristic, and state fixed effects. ResultsApproximately 29% of the 724,700 hospitalizations in the analytic dataset had incomplete home health referrals after discharge. The rate of incomplete home health referrals varied among clinical conditions, ranging from 17% among joint/musculoskeletal patients and 38% among digestive/endocrine patients. Risk-adjusted 1-year mortality and readmission rates were 1.4 and 2.4 percentage points lower and total spending was $1053 higher among patients with complete home health referrals as compared with those with incomplete home health referrals after hospital discharge. Conclusions and ImplicationsThe analysis revealed that almost 1 in 3 patients discharged from a hospital with a discharge status of home health does not receive home health care. In addition, complete home health referrals are associated with lower mortality and readmission rates and higher spending. As home health care utilization increases, policymakers should pay attention to the tradeoff between quality and cost when implementing alternative policies and payment models.

Reducing Length of Stay is not Associated with Increased Readmission Rates Following Lower Extremity Arterial Bypass

Objective: &#x0D; Traditional fee-for-service reimbursement models for medical services have been increasingly replaced with the merit-based and efficiency-driven pay-for-performance initiatives. Financial incentives to decrease expenditures have added pressure on hospitals and providers to reduce length of stay (LOS). Concern has been raised that this strategy may unwittingly increase readmission rates. We sought to better understand potential trade-offs between these two outcome measures for hospitals performing lower extremity arterial bypass (LEAB). &#x0D; Methods: &#x0D; We performed a retrospective observational cohort study of 479,366 Medicare beneficiaries undergoing LEAB in 1,708 hospitals from 2005-2009. Using LOS quintiles and a multiple logistic regression model, we generated risk-adjusted readmission rates (RARR) accounting for age, gender, pre-existing comorbidities, non-elective admission status, post-operative complications, and discharge destination. We then compared RARRs across LOS quintiles. Finally, we evaluated the association between hospital LOS on readmissions performance after adjusting for hospital volume, location, teaching status, bed size, and non-home discharges. &#x0D; Results: &#x0D; The mean hospital 30-day RARR was 14.5% (SD 3.5%) and the median LOS 4 days (range 3-6 days). Hospitals with the shortest median LOS (2.3 days) had slightly lower readmission rates compared to those with the highest median LOS (9.2 days) (13.3% vs 15.8%, p &lt;0.001). The Spearman correlation coefficient was 0.15 (p &lt; 0.001), indicating a very weak correlation between LOS and RARR. &#x0D; Conclusion and Potential Implications: &#x0D; At the hospital-level, there appears to be little tradeoff between LOS and RARR, implying these outcomes measure different domains of hospital quality and can be used as indicators of care quality and the likelihood for post-discharge adverse events. As it is possible for hospitals to perform well on both measures, pay-for-performance initiatives may consider incentivizing reducing LOS and readmissions. 

Variation in Surgical Spending Among the Highest Quality Hospitals for Cancer Surgery.

This study evaluates the variation in spending by the highest-quality hospitals performing complex cancer surgery in the United States. As mortality rates for high-risk cancer surgery have improved, increased attention has focused on other elements of quality, such as complications. However, high-value surgical care requires both high-quality care and cost savings. Therefore, understanding any residual cost variation among high-quality hospitals is essential to better direct efforts to achieve efficient, high-value care. Medicare beneficiaries age 65 to 99 who underwent surgery for pancreas, esophageal, lung, rectal, and colon cancer from 2014 to 2016 were identified. The highest-quality hospitals were identified as those in the quintile with the lowest risk- and reliability-adjusted serious complication rates for each operation. Within this cohort of high-quality hospitals, 30-day total episode, index hospitalization, physician, postacute care, and readmis-sion spending were analyzed. Logistic regression models were utilized to estimate the probability of postoperative outcomes and post-discharge resource utilization. A total of 43,007 Medicare patients underwent either pancreas, esophageal, lung, rectal, or colon resection for cancer at a hospital within the highest-quality quintile. Among the highest quality hospitals, total episode spending ranged from $18,712 for colectomy to $38,054 for esophagectomy. Spending between the lowest- and highest spending hospitals varied from $1207 [confidence intervals (CI 95% ) $1195-$1220] or 6.6% of total episode spending in the lowest tertile for colectomy to $5706 (CI 95% $5,506-$5906) or 16.1% of total episode spending in the lowest tertile for esophagectomy. The largest component of variation was from postacute care spending followed by readmission. For all operations, the risk-adjusted rate of postacute care facility utilization was lower among the lowest spending hospitals compared to the highest spending hospitals. For example, for pancreas the lowest-spending hospitals on average discharged patients to a postacute care facility at a rate of 18,6% (CI 95% 16.2-20.9) compared to 31.0% (CI 95% 28.2-33.9) in the highest-spending hospitals. In all operations, the risk-adjusted readmission rate was lower among the lowest-spending hospitals compared to the highest-spending hospitals. For instance, within the esophagus cohort, the lowest-spending hospitals had an average risk-adjusted readmission rate of 17.3% compared to 29.4% in the highest spending hospitals ( P < .001). Even among the highest-quality hospitals, significant cost variation persists among cancer operations. Postacute care variation, rather than residual variation in complication rates, explains the majority of this variation and represents an immediately actionable target for increased cost-efficiency.

Effects of post-discharge telemonitoring on 30-day chronic obstructive pulmonary disease readmissions and mortality

Introduction Much attention has been focused on decreasing chronic obstructive pulmonary disease (COPD) hospital readmissions. The US health system has struggled to meet this goal. The objective of this study was to assess the efficacy of telehealth services on the reduction of hospital readmission and mortality rates for COPD. Methods We used a cross-sectional design to examine the association between hospital risk-adjusted readmission and mortality rates for COPD and hospital use of post-discharge telemonitoring (TM). Data for 777 hospitals were sourced from the Centers for Medicare & Medicaid Services and the American Hospital Association annual surveys. Propensity score matching using the kennel weights method was applied to calculate the weighted probability of being a hospital that offers post-discharge TM services. Results Hospitals with post-discharge TM had about 34% significantly higher odds (adjusted odds ratio (AOR) = 1.34; 95% confidence interval (CI) 1.06–1.70) of 30-day COPD readmission and 33% significantly lower odds (AOR = 0.67; 95% CI 0.50–0.90) of 30-day COPD mortality compared to hospitals without post-discharge TM services. Discussion Overall, hospitals that offer post-discharge TM services have seen an improvement in 30-day COPD mortality rates. However, those same hospitals have also experienced a significant increase in 30-day COPD readmissions. TM can potentially decrease mortality in patients recently admitted for acute exacerbation of COPD. The results provide further evidence that readmissions present a problematic assessment of health-care quality, as the need for readmission may or may not be directly related to the quality of care received while in hospital.

Trends in 30-Day Readmission for Medicaid and Privately Insured Pediatric Patients: 2010-2017.

Children insured by Medicaid have higher readmission rates than privately insured children. However, little is known about whether this disparity has changed over time. Data from the 2010 to 2017 Healthcare Cost and Utilization Project Nationwide Readmissions Database were used to compare trends in 30-day readmission rates for children insured by Medicaid and private insurers. Patient-level crude and risk-adjusted readmission rates were compared by using Poisson regression. Hospital-level risk-adjusted readmission rates were compared between Medicaid- and privately insured patients within a hospital by using linear regression. Approximately 60% of pediatric admissions were covered by Medicaid. From 2010 to 2017, the percentage of children with a complex or chronic condition increased for both Medicaid- and privately insured patients. Readmission rates were consistently higher for Medicaid beneficiaries from 2010 to 2017. Readmission rates declined slightly for both Medicaid- and privately insured patients; however, they declined faster for privately insured patients (rate ratio: 0.988 [95% confidence interval: 0.986-0.989] vs 0.995 [95% confidence interval: 0.994-0.996], P for interaction <.001]). After adjustment, readmission rates for Medicaid- and privately insured patients declined at a similar rate (P for interaction = .87). Risk-adjusted hospital readmission rates were also consistently higher for Medicaid beneficiaries. The within-hospital difference in readmission rates for Medicaid versus privately insured patients remained stable over time (slope for difference: 0.015 [SE 0.011], P = .019). Readmission rates for Medicaid- and privately insured pediatric patients declined slightly from 2010 to 2017 but remained substantially higher among Medicaid beneficiaries suggesting a persistence of the disparity by insurance status.
