Mental health and well-being are crucial for a fulfilling life. Work related stress negatively impacts health care providers' professionalism, quality of care delivery, efficiency, and overall quality of life. It is important to identify and mitigate these work-related risk factors to protect the mental health well-being of healthcare workers. The aim of this study was to assess the provision, demand and awareness of need for mental health care services amongst nursing care staff stationed in dispensaries within Mombasa County, Kenya. This is a cross-sectional study that targeted nurses at the dispensary level, facility in-charges, and County health personnel. Quantitative data was collected using GAD-7 to measure anxiety, PHQ 9 to measure depression and PCL 5 to measure PTSD. Qualitative data was collected through IDI and key informant interviews with the facility in charges and the Sub-County County nurse officials. Quantitative data was analyzed descriptively while qualitative data was analyzed following Creswell six steps. The research discovered the proportion of nurses in Mombasa County affected by PTSD severe anxiety and severe depression as 12.6%, 22.6% and 3.2% respectively. These conditions have their origin in work and personal matters with work-related matters being the main contributors. Fear of stigmatization from colleagues and the community negatively affected care seeking behavior. Nine county facilities offered mental health services although understaffed with only 9 specialized staff. The county has made some investment in mental health service provision, this investment is however focused on service provision to the general public as opposed to health care workers.
