In today’s world, delivery of health care is under immense pressure and this may result in low quality of medical consultation. As a consequence, there is a need to regularly evaluate medical consultations to improve efficiency and competitive advantages regarding cost-effectiveness and quality of care. However, few studies have evaluated medical consultation, especially on non-communicable conditions. Thus, this study assessed the knowledge and satisfaction of diabetic outpatient clients on medical consultations. A descriptive cross-sectional study was conducted at a diabetic clinic within Bungoma county referral hospital. The purposive sampling method was used to recruit 137 participants; data was collected using both qualitative and quantitative approaches using a Semi-structured questionnaire. Key informant interviews were conducted with technical staff, the structured part of the questionnaire was based on demographic characteristics, Patient knowledge, and level of Satisfaction. The questionnaire was translated into Kiswahili and Luhya and pretested for better understanding. The descriptive data analysis was carried out using a statistical package for the social sciences (SPSS) version 23.0. For qualitative data, thematic content analysis was used. Data was presented using tables with frequencies and percentages. There was an equal representation between males and females with a majority of the respondents being elderly persons between 40 – 50 years representing 52 (43.3%), with 72 (60%) respondents have gone past secondary school education, and 40 (33.3%) of the respondents were farmers. All respondents indicated that diabetes glycemic control is the most available service with 106 (88.3%) agreeing that diabetes screening is offered while 97 (80.8%) indicating that management of diabetic complications is the least available service. The majority of the respondents, 104 (86.6%) knew about diabetes while 12, (10%) were not sure and 4, (3.3%) did not. A total of 72 (60%) were satisfied, 40 (33.4%) were somehow satisfied, 4(3.3%) were not satisfied. The study concluded that the majority of diabetic medical consultation services are available, the majority of clients/patients knew about diabetes and patients were largely satisfied with the medical consultant services. The ministry of health and the county department of health should ensure all the necessary diabetic medical consultation services meet the expected standards, improve diabetes awareness through radio and television, and attitude change among health providers to improve quality of care and satisfaction rates.
