ABSTRACT   BACKGROUND፡ Timely entry to an antenatal care with a healthcare provider who follows a set of national guidelines is assumed to ensure higher levels of client satisfaction. It is also expected to improve perinatal outcomes.  Little is known about the level of adherence of Ethiopian providers to these guidelines. Therefore, this study aims to assess the proportion of clients who received complete (100%) provider adherence to antenatal care guidelines at the first visit and client associated factors in Gondar Town. METHODS: A cross-sectional study of 834 study participants was conducted in public health facilities of Gondar Town in Ethiopia. An 18 point checklist was used to observe provider adherence to the first antenatal care visit guidelines. Descriptive statistics and multivariable binary logistic regression model were done by using STATA 14 software. RESULT: The proportion of clients who received the complete provider’s adherence to the first antenatal care guideline was 32.25% (95% CI: 29.1-35.5). The mean adherence score was 16.78%. Women who had prior history of pregnancy and/or birth-related complications (AOR = 1.58; 95%CI: 1.04-2.04) and late antenatal care booking at gestational week 16 or greater (AOR = 1.45; 95%CI: 1.03-2.03) were significantly associated with clients receiving complete providers’ adherence to the first antenatal guideline. CONCLUSIONS: We found the level of adherence to national antenatal care guidelines during first visit as surprisingly low. When considering to upgrade the guidelines to the actual WHO guideline of eight visits, we recommend that refresher training be provided regularly to help staff understand the importance of following the guidelines as closely as possible. Perhaps, we need to learn more from the health care providers themselves about their reasons for not following the guidelines. KEYWORDS: Complete provider adherence, first ANC visit, Ethiopia
