No difference in readmission risk seen for one- vs two-midnight length of stay for TKA
No difference was seen between one-midnight and two-midnight length of stay for primary total knee arthroplasty regarding 90-day readmission risk, according to recently published results.
Researchers performed a retrospective review of the Michigan Arthroplasty Registry Collaborative Quality Initiative database and identified 46,709 TKA procedures during a 5-year period for patients who had either a one-midnight or two-midnight length of stay (LOS). Inpatient readmission within 90 days postoperatively was the study endpoint. The odds of 90-day readmission between one-midnight and two-midnight LOS were compared with a multiple logistic regression model and propensity score matching. Other endpoints included 90-day complications.
Results showed no difference in the odds of 90-day readmission between patients who had a one-midnight LOS and those who had a two-midnight LOS for primary TKA. Investigators noted increased odds of 90-day readmission were linked to male sex, single marital status, age of 80 years or older, type I diabetes, previous smoking, narcotic use prior to surgery and a higher American Society of Anesthesiologists scores. Decreased odds of readmission were seen in patients between the ages of 50 and 64 years, those with a higher preoperative hemoglobin level and those with a positive social history of alcohol abuse. –by Monica Jaramillo
