A study which looked at the safety of same-day discharge after total knee arthroplasty (TKA) or total hip arthroplasty (THA) has found it is associated with higher odds of cardiac/pulmonary complications compared with a one-day length of stay.
The population-based observational study included 226,481 TKA and 140,557 THA patients who underwent surgery between 2011 and 2017. Researchers compared 30-day complications and readmission rate and risk in patients discharged on the day of surgery (LOS 0) to those with a LOS of 1 day (LOS 1) and a standard practice group with LOS 2-3 days (reference group).
The study did not find statistically significant differences in unplanned readmission between LOS 0 and LOS 1 group in TKA or THA patients. However, the LOS 0 group showed higher odds of cardiac/pulmonary complications in both TKA (OR 1.95; 95% CI 1.20-3.16) and THA (OR 1.96; 95% CI 1.05-3.64) when compared with the LOS 1 group. TKA patients in the LOS 0 group also had higher odds of major complications than LOS 1 patients.
Presenting the findings in the BMJ Open, the authors said the trend towards increasing discharges on the same day of surgery after TKA and THA should be approached with caution.
