Trends in unplanned readmissions over 15 years: a regional Australian perspective

Causes for 30-day readmissions and accuracy of the LACE index in regional Victoria, Australia

BACKGROUND

Clinicians and funders continue to search for ways to reduce costs without sacrificing quality of care. Ongoing research should focus on innovative care models that identify patients at high-risk for hospitalisation and thereby reduce healthcare costs.

AIMS AND OBJECTIVES

This study examined readmission rates, comorbidity profiles and the performance of the LACEi (Length of stay, Acuity of admission, Charlson Comorbidity Index, ED admissions in the previous 6 months index) to predict the risk of 30-day readmissions in a regional population. Furthermore, we tested a novel clinician-orientated classification for the causes of 30-day readmissions.

DESIGN

Using a nested case-control design, data were extracted from administrative health records using 30-day readmission status as the outcome. We defined cases as discharges within 30 days before readmission and controls without a discharge within 30 days before admission between 1 July 2020 and 30 June 2022.

SETTING

The study was conducted at South West Healthcare in Victoria, Australia.

PARTICIPANTS

All adult medical patients were discharged alive from the facility. We excluded planned readmissions, surgical and obstetric admissions, dialysis, transfers to alternative facilities and discharges against medical advice.

MAIN OUTCOME MEASURES

Thirty-day readmission rate, comorbidity profile for all admissions, LACEi for all admissions, the performance of the LACEi in our setting and the causes leading to readmission using a clinician-orientated classification tool.

RESULTS

Comorbidity burden, male sex and age > 65 years were associated with increased readmission risk but not length of stay. The LACEi demonstrated modest predictive ability to identify high-risk patients for readmissions (area under the receiver operating characteristic curve = 0.59). Additional variables were needed to increase accuracy. The novel classification identified 42% of readmissions as potentially avoidable.

CONCLUSION

Our study identified comorbidity burden, male sex and age ≥ 65 years as critical indicators for readmission risk. Although the LACEi showed moderate predictive ability, additional variables were needed for increased accuracy. Over 40% of readmissions were potentially avoidable, and nearly two thirds occurred within 14 days of discharge from the hospital.

Effectiveness of Hospital-Based Interventions by Occupational Therapy Practitioners on Reducing Readmissions: A Systematic Review With Meta-Analyses

IMPORTANCE

Readmission to the hospital can lead to poorer patient outcomes and increased health care costs. The effect of occupational therapy interventions for adult hospitalized patients on readmission rates has not been previously evaluated.

OBJECTIVE

To systematically examine the published literature to determine the effects of occupational therapy interventions for adult hospitalized patients on readmission rates.

DATA SOURCES

Systematic search of five electronic databases was performed from database inception until May 2020, supplemented by citation and reference list searches. Study Selection and Data Collection: This review is reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and was registered prospectively; methodological quality of the included studies was assessed using the Downs and Black checklist. Meta-analyses were conducted with clinically homogeneous data; the overall body of evidence was graded for quality.

FINDINGS

Meta-analysis of 7 studies with 16,718 participants provided low-quality evidence that 1-mo readmission rates were reduced when adult patients hospitalized for general medical and surgical care received additional occupational therapy interventions compared with standard care. Subgroup analysis of 4 studies provided moderate-quality evidence that interventions focusing on the transition from hospital to the community were effective in reducing 1-mo readmissions to hospitals compared with standard care.

CONCLUSIONS AND RELEVANCE

Occupational therapy interventions can be effective in reducing readmissions among some adult hospitalized patient populations, including those admitted for surgery or management of acute medical conditions, with stronger evidence to support transitional care interventions. What This Article Adds: Occupational therapy interventions can be effective in reducing readmissions among adult hospitalized patients. There is a continued need for occupational therapy practitioners to understand their value and contribution to reducing avoidable readmissions to hospitals.
