Long-term outcomes among Medicare patients readmitted in the first year of hemodialysis: a retrospective cohort study.

ABSTRACT:

Background

Readmission within 30?days of hospital discharge is common and costly among end-stage renal disease (ESRD) patients. Little is known about long-term outcomes after readmission. We estimated the association between hospital admissions and readmissions in the first year of dialysis and outcomes in the second year.

Methods

Data on incident dialysis patients with Medicare coverage were obtained from the United States Renal Data System (USRDS). Readmission patterns were summarized as no admissions in the first year of dialysis (Admit-), at least one admission but no readmissions within 30?days (Admit+/Readmit-), and admissions with at least one readmission within 30?days (Admit+/Readmit+).We used Cox proportional hazards models to estimate the association between readmission pattern and mortality, hospitalization, and kidney transplantation, accounting for demographic and clinical covariates.

Results

Among the 128,593 Medicare ESRD patients included in the study, 18.5% were Admit+/Readmit+, 30.5% were Admit+/Readmit-, and 51.0% were Admit-. Readmit+/Admit+ patients had substantially higher long-term risk of mortality (HR?=?3.32 (95% CI, 3.21-3.44)), hospitalization (HR?=?4.46 (95% CI, 4.36-4.56)), and lower likelihood of kidney transplantation (HR?=?0.52 (95% CI, 0.44-0.62)) compared to Admit- patients; these associations were stronger than those among Admit+/Readmit- patients.

Conclusions

Patients with readmissions in the first year of dialysis were at substantially higher risk of poor outcomes than either patients who had no admissions or patients who had hospital admissions but no readmissions. Identifying strategies to both prevent readmission and mitigate risk among patients who had a readmission may improve outcomes among this substantial, high-risk group of ESRD patients.

Project description:To assess the clinical outcomes of patients who received direct percutaneous endoscopic jejunostomy (DPEJ) for enteral feeding.This is a 10-year cohort study in a single tertiary center. Main outcome measurements were technical success, and short- and long-term outcomes. DPEJ was attempted in 83 patients (51 men; 55 ± 2 years) for dysphagia (n = 35), gastroparesis with recurrent aspiration (n = 30), and levodopa drug infusion for severe Parkinson's disease (n = 18).DPEJ was successful in 75 (90 %) patients. All technical failures were related to the inability to find adequate trans-illumination, and were not influenced by BMI, age, gender, or indication. Peri-operative (30-day) adverse events occurred in 11 (13 %) patients, including wound infection (3), leakage around the stoma (4), minor bleeding requiring no intervention (2), and aspiration (1). There was one case (1.2 %) of gastric perforation after PEJ insertion for levodopa drug infusion trial. This 60-year-old woman required an emergency laparotomy with nil complications, and levodopa drug infusion recommenced successfully. One case of intestinal perforation (1.2 %) occurred after jejunostomy tube replacement at 6 months of insertion, which was successfully managed with surgery. There were no peri-operative deaths. Adequate delivery of enteral feeding or Duodopa drug was achieved in 66/73 (90 %) patients, with evidence of weight gain or improvement in Parkinson's disease. Seven (8 %) continued to have clinical regurgitation but not aspiration. After a median follow-up of 84 months, 27 (33 %) patients died of their underlying diseases. Seven (8 %) had marked improvement in their underlying disease and had PEJ removed after 5 months (range 1 - 8 months).Single center study.DPEJ is associated with a high technical success rate (90 %), a relatively low rate of peri-operative adverse events (13 %) and an improvement in long-term nutritional support in the majority of patients (90 %). DPEJ should be the procedure of choice to gain enteral access for feeding or drug delivery prior to considering surgery.

Project description:BackgroundPost-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.MethodsThis 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.ResultsAmong 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.ConclusionsIn 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.
