Background: Health workers adherence to health care facility standards are complicatedrnprocesses. So when health professionals comply with standards, they must first become aware ofrnthe standards, then intellectually agree with them, and then decide to adopt them in the care theyrnprovide, then regularly adhere to them at appropriate times.. Health workers can simply not be familiar rnwith standards because they have not been communicated clearly. Commonly, providers are aware ofrnstandards but may hold beliefs or attitudes that inhibit them from adhering to standards.Nevertheless,rnevidence on awareness and adherence to healthcare facility standards among health workers working inrnprivate health facility in low income countries is poor. rnObjectives:The aim of this study was to assess level of awareness and adherence to healthcare facilityrnstandards among health workers in selected private medium clinics in Addis Ababa. rnMethods:A Facility based cross-sectional descriptive study design was used to conduct the study and thernstudy units were selected using simple random sampling technique. Descriptive statistics includingrnfrequencies and percent were used in order to summarize variables. To determine the association betweenrneach variable binary logistic regression model was used and variables with p-value less than 0.05 werernconsidered as statistically significant. OR and CI was used to see the strength of the association betweenrnthe independent variables and awareness and adherence. rnResult; A total of 250 participants were included in the study which makes the response rate 89.6%rnwith mean age of 26.82 years. The majority which 62.8% of them were female, 67.2 % were heardrnabout Ethiopian medium clinic standards, even though 98.4% of them had no on job trainings onrnit. Further, 22.4% and 44.8% of the study participants had good level of awareness and adherencernrespectively. Factors such as being the age interval of 21-25 years (AOR 0.19, 95%CI (0.06, 0.60))rnand 26-30 years of old (AOR 0.06, 95% CI (0.01, 0.32)) had statistical significance associationrnwith level of adherence as compared to 20 years and below age group. But not participated inrninforming about Ethiopian medium clinic standard (AOR 1017.49, 95% CI (35.99, 28768.10)) wasrnthe only variable which had statistically significant association with level of awareness.rnConclusion and recommendation; the current study result indicated that almost more than halfrnof participants had poor level of awareness and adherence toward Ethiopian medium clinic standards.Therefore, providing continuous pre-recruitment and on job educational training onrnEthiopian medium clinic standared by the health institutions is essential.
