Validation of the Thai version of the obstetric quality of recovery score (obsqor-10-Thai) after elective cesarean delivery

A narrative review of the literature relevant to obstetric anesthesiologists: the 2023 Gerard W. Ostheimer lecture

This narrative review of the 2023 Gerard W. Ostheimer lecture presented at the Society for Obstetric Anesthesia and Perinatology 2023 annual meeting summarizes 2022 literature relevant to obstetric anesthesiologists.

ANTENATAL STUDIES

Neonatal morbidity is reduced with antenatal maternal buprenorphine compared with methadone for treatment of opioid use disorder. Antenatal pregnancy allergy testing is safe and feasible.

ANALGESIA AND ANESTHESIA STUDIES

Intrathecal (IT) 3% chloroprocaine for cervical cerclage results in faster sensory block resolution and discharge readiness compared with bupivacaine. The ED90 of 3% chloroprocaine (with IT fentanyl 10 µg) is 49.5 mg. Dural puncture epidural technique does not improve the quality of labor analgesia in obese parturients compared with epidural analgesia. Low- (>0.08 to ≤0.1%) and ultra-low (<0.08%) concentrations of bupivacaine for epidural analgesia maintenance result in similar maternal and neonatal outcomes. Lower doses of first line uterotonic agents are non-inferior to higher doses (oxytocin 0.5 IU vs. 5 IU and carbetocin 20 vs. 100 µg) in patients at low risk for postpartum hemorrhage. Supplemental analgesia or conversion to general anesthesia is necessary in approximately 15% of elective cesarean deliveries. Intravenous dexamethasone improves analgesia outcomes, however optimal dosing and timing remain unclear; it may induce neonatal hypoglycemia in the setting of gestational diabetes.

POSTPARTUM STUDIES

A core outcome set may help evaluate enhanced recovery protocol implementation. History of migraine and accidental dural puncture (ADP) above the L3 level are associated with epidural blood patch (EBP) failure and ADP at or below L3 and >48 h interval between ADP and EBP are associated with success.

Validation of Hindi version of the obstetric quality of recovery score-11 (ObsQoR-11 H) following elective caesarean section

Background and Aims

Obstetric quality of recovery score-11 (ObsQoR-11) was developed in English to evaluate the quality of recovery in the caesarean section. We aimed to validate the Hindi version of ObsQoR-11 (ObsQoR-11H) for Hindi-speaking patients to evaluate the quality of recovery following the elective caesarean section.

Methods

The ObsQoR-11 was translated into Hindi and assessed for validity, acceptability and feasibility. The questionnaire was administered postoperatively at 24 and 48 hours, and the Global Health Numeric Rating Scale (NRS) was used to evaluate recovery.

Results

The mean (standard deviation [SD]) (95% confidence interval [CI]) ObsQoR-11 H was 75.94 (4.09)(95% CI 75.1, 76.7) and 80.25 (4.08)(95% CI 79.5, 81) at 24 and 48 hours, respectively. The mean (SD) (95%CI) Global Health NRS scores were 71.22 (5.97)(95% CI 70, 72.4) and 77.37 (5.79)(95% CI 76.2, 78.5) at 24 and 48 hours, respectively. Convergent validity showed a strong correlation between ObsQoR-11H and Global Health NRS (Spearman's correlation coefficient [rs] >0.8 and 0.78) scores at 24 and 48 hours, respectively. Discriminant validity was significant in appreciating the difference between good and poor recovery (P < 0.001). Split-half coefficient of 0.69 and 0.65 and Cronbach's alpha (α) of 0.91 and 0.82 at 24 and 48 hours suggested good score reliability. The acceptability and feasibility of the score were also good.

Conclusion

The ObsQoR-11H discriminated well between 'good' and 'poor' recovery and correlated strongly with Global Health NRS scores. It was found to be a valid, reliable, acceptable and feasible tool for psychometric recovery evaluation after elective caesarean section in Hindi-speaking women.

Translation and validation of the French version of the ObsQoR-10 questionnaire for the evaluation of recovery after delivery: the ObsQoR-10-French

Background

The Obstetric Quality of Recovery-10 (ObsQoR-10) is a validated tool for assessing the quality of postpartum recovery. This study aimed to validate the French version of the ObsQoR-10 scale (ObsQoR-10-French).

Methods

After translating the ObsQoR-10 into French, we conducted a psychometric validation involving internal consistency, convergent validity, construct validity, reliability, responsiveness, scaling properties, acceptability, and feasibility. French women who underwent either a vaginal delivery (spontaneous or induced labour), or an emergency or elective Caesarean section (C-section) were prospectively included. They completed the ObsQoR-10-French before delivery and at 24 h (H24) and 48 h (H48) after delivery.

Results

Of the 500 women included, 431 (86%) completed the questionnaire at all three timepoints. A total of 352 women (82%) underwent vaginal delivery (with 228 [53%] experiencing spontaneous labour and 124 [29%] had labour induced), whereas 53 (12%) women underwent an emergency C-section and 26 (6%) an elective C-section. The ObsQoR-10-French demonstrated excellent internal consistency with a Cronbach's coefficient of 0.81, 95% confidence interval 0.78-0.84 at H24. The tool was correlated with an 11-item global health score (P<0.001). Of the list of hypotheses for evaluating the construct validity, 81% were confirmed (negative associations between ObsQoR-10-French and length of labour, hospital stay, the need for a C-section, and the emergency level of the C-section). The Cohen effect size at H24 was 0.58. The intra-class coefficient was 0.90, 95% confidence interval 0.86-0.93 at H24.

Conclusion

The ObsQoR-10-French is a valid and reliable psychometric questionnaire, capable of assessing the quality of postpartum recovery in French-speaking populations.
