Insights
Surgical readmissions show that patients readmitted multiple times utilize more hospital resources and face higher mortality risks. Identifying readmission factors can optimize outpatient services and reduce future inpatient costs.
Area of Science:
- Surgical outcomes research
- Healthcare resource utilization analysis
Background:
- Hospital readmissions represent a significant challenge in surgical patient care.
- Understanding patterns of surgical readmissions is crucial for improving patient outcomes and managing healthcare costs.
Purpose of the Study:
- To analyze surgical readmission rates and resource utilization in adult patients.
- To identify factors associated with increased likelihood of surgical readmission.
- To explore potential strategies for reducing future inpatient costs through outpatient services.
Main Methods:
- Retrospective analysis of adult surgical patients requiring readmission.
- Stratification of readmissions based on the number of readmissions per patient (1-5 times).
- Evaluation of hospital resource utilization, financial risk (DRG payment), and mortality across readmission strata.
Main Results:
- 41.1% of surgical readmissions involved patients readmitted more than once; 4.4% were readmitted five or more times.
- Patients with three or more admissions exhibited the highest hospital resource utilization, financial risk, and mortality.
- Specific factors correlating with a higher likelihood of surgical readmission were identified.
Conclusions:
- Resource utilization and outcomes in surgical readmissions vary significantly based on the number of readmissions per patient.
- Identifying high-risk readmission factors can inform targeted interventions.
- Focusing on outpatient services for at-risk patients may reduce future hospital inpatient costs.
Abstract:
We analyzed all adult surgical patients requiring readmission to the surgical service of an acute care academic hospital for a four-year period (1/1/85-12/31/88). We stratified surgical readmissions by the number of times the patient was readmitted to surgery (from one to five times). For surgical patients 41.1 per cent of the readmission population was readmitted more than once, only 4.4 per cent were readmitted five or more times. Patients requiring three or more admissions generally had the greatest hospital resource utilization, financial risk under DRG payment, and mortality, compared with other surgical readmissions. This analysis suggests that within the surgical readmission population resource parameters may differ by the number of readmissions per patient. Factors were identified which corresponded to a greater likelihood of surgical readmission, and possibly allow the focus of outpatient services which may reduce hospital inpatient costs in the future.
