Rapid-recovery protocol for minimally invasive mitral valve repair

Abstract

Background

Minimally invasive mitral valve repair (MIMVR), often performed within specialized care pathways, has been shown to reduce hospital length of stay and improve patient recovery. The relative value of rapid-recovery protocols as a component of care pathways, including enhanced recovery programs (ERPs), has not been well described. This study compared clinical outcomes following implementation of a new, comprehensive rapid-recovery protocol within a previously established, mature ERP for patients undergoing MIMVR.

Methods

The rapid-recovery protocol was developed and implemented by a multidisciplinary team to further optimize patient recovery within an existing ERP. The protocol was applied to 75 consecutive patients undergoing MIMVR between September 2022 and December 2023. Outcomes were compared retrospectively to 75 ERP control patients who did not receive the rapid-recovery protocol but experienced the ERP. The primary outcome was a composite of discharge from the intensive care unit (ICU) by postoperative day (POD) 1, discharge to home by POD 4, and no all-cause hospital readmission by 30 days.

Results

Baseline characteristics were similar in the 2 groups. Patients in the rapid-recovery group achieved the primary composite outcome significantly more often compared to the control group (60% vs 40%, respectively). There was no between-group difference in postoperative complications. Multivariable logistic regression showed that age ≤60 years was significantly associated with rapid-recovery protocol success. Clinical barriers to achieving individual components of the primary outcome were described.

Conclusions

A rapid-recovery protocol for MIMVR was associated with early ICU and hospital discharge. These benefits were safely achieved without any increase in hospital readmission, morbidity, or mortality up to 30 days postoperatively.
