Background: The effect of dolutegravir (DTG)-based regimens on reducing attrition from care among women enrolled in the prevention of mother-to-child transmission (PMTCT) care program is unknown. Therefore, this study aimed to compare the incidence of attrition among women exposed to DTG-based with those exposed to efavirenz (EFV)-based first-line antiretroviral therapy (ART) in Ethiopia. Methods: An uncontrolled before-and-after study was conducted involving 932 women (with 466 on EFV-based and 466 on DTG-based regimens) who were enrolled in the PMTCT care program from September 2015 to February 2023. The outcome variable was attrition (i.e., maternal death or loss to follow-up before their infants' final HIV status was determined). A Kaplan-Meier estimator was employed to estimate the probability of attrition. The Cox proportional hazards regression model was fitted to identify predictor variables. The adjusted hazard ratio (aHR) with the corresponding 95% confidence interval (CI) was calculated to examine the risk difference in the comparison groups. Results: The cumulative incidence of attrition among women was 5.2% (3.0% for those placed in the DTG-based regimen arm and 7.3% for those placed in the EFV-based regimen arm). Women on DTG-based regimens had a 57% (aHR: 0.43; 95% CI: 0.23-0.80) lower risk of attrition from care compared to those on EFV-based regimens. Women who delivered their infants at home (aHR: 2.35; 95% CI: 1.14-4.85), had poor/fair adherence (aHR: 3.23; 95% CI: 1.62-6.45), had unsuppressed/unknown viral load status (aHR: 2.61; 95% CI: 1.42-4.79), and did not disclose their status to partners (aHR: 2.56; 95% CI: 1.34-4.92) had a higher risk of attrition from PMTCT care compared to their counterparts. Conclusion: The cumulative incidence of attrition among women receiving PMTCT care is optimal. In addition, the risk of attrition among women receiving DTG-based regimens is lower than that among women receiving EFV-based regimens. Thus, DTG-based first-line ART regimen supplementation should be sustained to achieve a national retention target of 95% and above
