IntroductionRespectful maternity care is an approach that involves respecting women’s belief, choices, emotions, and dignity during the childbirth process. As the workload among maternity care workforce affects intrapartum quality care, respectful maternity care might have also been affected, particularly during the pandemic. Thus, this study was conducted to examine the association between workload among healthcare providers and their practice of respectful maternity care, before and during the early phase of pandemic.MethodsA cross-sectional study was conducted in South Western Nepal. A total of 267 healthcare providers from 78 birthing centers were included. Data collection was done through telephone interviews. The exposure variable was workload among the healthcare providers, and the outcome variable was respectful maternity care practice before and during the COVID-19 pandemic. Multilevel mixed-effect linear regression was used to examine the association.ResultsThe median client-provider ratio before and during the pandemic was 21.7 and 13.0, respectively. The mean score of respectful maternity care practice was 44.5 (SD 3.8) before the pandemic, which was decreased to 43.6 (SD 4.5) during the pandemic. Client-provider ratio was negatively associated with respectful maternity care practice for both times; before (Coef. -5.16; 95% CI -8.41 to -1.91) and during (Coef. -7.47; 95% CI -12.72 to -2.23) the pandemic.ConclusionsWhile a higher client-provider was associated with a lower respectful maternity care practice score both before and during the COVID-19 pandemic, the coefficient was larger during the pandemic. Therefore, workload among the healthcare providers should be considered before the implementation of respectful maternity care, and more attention should be given during the pandemic.Supplementary InformationThe online version contains supplementary material available at 10.1186/s12913-023-09561-x.
