Insights
Readmissions after knee and hip arthroplasty occur for various reasons, with surgical complications being a major factor. Identifying readmission types is crucial for effective preventative strategies.
Area of Science:
- Orthopedic Surgery
- Arthroplasty Research
- Patient Outcomes
Background:
- Readmissions after joint replacement surgery impact patient recovery and healthcare costs.
- Understanding readmission patterns is essential for improving post-operative care.
Purpose of the Study:
- To investigate the causes and rates of 90-day readmissions following primary and revision knee and hip arthroplasties.
- To categorize readmissions by type and relation to the index admission.
Main Methods:
- Retrospective analysis of 1,516 patients undergoing primary or revision total hip arthroplasty (THA) or total knee arthroplasty (TKA).
- Analysis of all readmissions within 90 days, categorized by planned/unplanned and related/unrelated to the index admission.
Main Results:
- Overall 90-day readmission rate was 5.61%, varying by procedure (2.35-6.74%).
- Unplanned, index-related readmissions constituted 60% of total readmissions, with 82% due to surgical reasons.
- Planned, unrelated readmissions were also common (31.76%); 48.23% of all readmissions occurred within 30 days.
Conclusions:
- Readmissions after knee and hip arthroplasty stem from diverse causes.
- Differentiating readmission types is vital for developing targeted interventions and enhancing preventative measures.
Objectives:
The aim of the study was to investigate the causes and rates of readmissions within 90 days after primary and revision knee and hip arthroplasties.
Patients And Methods:
A total of 1,516 patients (290 males, 1,226 females; mean age 64.7±10.5 years; range, 21 to 91 years) who underwent primary total hip arthroplasty (THA), primary total knee arthroplasty (TKA), revision THA, and revision TKA between January 2013 and December 2014 were retrospectively analyzed. All readmissions within 90 days as of discharge dates of patients were analyzed and were categorized as planned readmissions related to the index admission, unplanned readmissions related to the index admission, planned readmissions unrelated to the index admission and unplanned readmissions unrelated to the index admission.
Results:
Readmission rate in the overall of study group was found to be 5.61%. This rate varied depending on the procedure applied, ranging between 2.35 and 6.74%. Unplanned readmissions related to the index admission within 90 days consisted of 60.0% of total readmissions. A total of 82.0% of readmissions within 90 days was due to surgical reasons. Planned readmissions unrelated to the index admission within 90 days were also frequently seen (31.76%). Totally 48.23% of total readmissions within 90 days occurred within the first 30 days. A total of 48.23% of the total readmissions and 58.82% of the readmissions which were unplanned and related to the index admission occurred within the first 30 days.
Conclusion:
After knee and hip arthroplasties, readmissions occur due to various reasons. Therefore, it is of utmost importance to identify the readmission type in the evaluation of readmissions which may increase the effectiveness of precautions to be taken.
