Evaluation of the relationship between the Obstetric Comorbidity Index (Ob-CMI) and the Obstetric Quality Of Recovery Score (ObsQoR-11): a prospective observational study.

BACKGROUND

Caesarean delivery is a common surgical procedure associated with significant maternal morbidity and mortality. Delayed postoperative recovery is a critical concern influenced by various factors. This study evaluates whether the Obstetric Comorbidity Index (OB-CMI) predicts postoperative recovery quality, hypothesizing a correlation with the Obstetric Quality of Recovery score (ObsQoR-11).

METHODS

In our prospective observational study, patients' demographic data, medical history, ASA score, gravida, parity, gestational age, caesarean delivery category and indication if emergency, OB-CMI, anaesthesia method, intraoperative bleeding and transfusion of blood products, complications, postoperative analgesia use, the duration of hospitalization, the need for admission to intensive care unit and duration (if applicable) and the discharge status were recorded. The primary outcome was the correlation between OB-CMI and ObsQoR-11 scores on postoperative days 1 and 2. Secondary outcomes included comparisons of ObsQoR-11 scores across caesarean categories and anaesthesia techniques.

RESULTS

There were 214 patients included in this study. A negative significant correlation was found between the OB-CMI and the ObsQoR-11 score on day 1 (R: -0.286, P <0.001) and day 2 (R: -0.225, P =0.001). The OB-CMI was found to be significantly lower in patients who received neuraxial anaesthesia compared to those who received general anesthesia (P =0.009). The ObsQoR-11 score was found to be significantly lower in patients who received general anaesthesia compared to patients who received neuraxial anaesthesia.

CONCLUSION

A negative correlation between preoperative OB-CMI and postoperative ObsQoR-11 scores suggests that OB-CMI may serve as a valuable preoperative tool for predicting recovery quality in caesarean delivery cases.
