Introduction Women experiencing substance use disorders (SUD) have often reported challenges in their relationships with health care providers during the perinatal period that served as a barrier to care. Establishing trust is an important aspect in forming positive relationships. The purpose of this study was to identify provider characteristics associated with the development of trust when caring for women experiencing SUD during the perinatal period. Methods A systematic search was conducted using the databases of CINAHL, APA PsychINFO, and PubMed along with a manual search of Google Scholar between the years of 2000-2021. Studies were included if they were (1) original qualitative research; (2) published in English; (3) peer reviewed; (4) from the perspective of women experiencing SUD; (5) included descriptions of positive health care interactions between women experiencing SUD in the perinatal period and their health care providers; and (6) conducted in the United States or Canada. The studies were assessed for quality and validity using 10 criteria from the Joanne Briggs Institute critical appraisal checklist for qualitative research. Results Findings from 21 qualitative studies were synthesized using a thematic synthesis approach and revealed 3 overarching themes that included 7 descriptive subthemes which identified provider characteristics associated with trust. The 7 descriptive subthemes included: developing rapport with women, demonstrating caring behaviors, including women in care, understanding women's SUD treatment efforts, reassuring women, delivering competent care, and educating women. Discussion Participants' accounts of trusting interactions with health care providers occurred when providers viewed women approvingly, affirmed their treatment efforts and maternal abilities, and delivered competent care that was knowledgeable of issues associated with SUD. The findings suggest the importance of confronting implicit biases, integrated care, and fostering a stigma-free and trauma-informed working environment.
