Utilizers' satisfaction is a multifaceted and a very challenging outcome to define. Patient expectations of care and attitudes greatly contribute to satisfaction. Other psychosocial factors, including pain and depression, are also known to contribute to utilizer's satisfaction scores. Objectives: Were to assess the utilizers' satisfaction with health care services provided by New Damietta Health Center and to determine health care providers' opinions about the causes of the users satisfaction from their points of view and how to improve it. Methods: A cross sectional study was conducted on the attendants of New Damietta General Health Center. The study included 130 health care utilizers and 49 health care providers from first of April to end of June 2014. Data collection was performed by an interview questionnaire. Results: The results showed that out of 130 health care utilizers, 96 (73.8%) were females, 91 (70.0%) were in the age group 19-45 years, and the overall rating of services as reported by the users was 62.46%. About half (46.2%) of the respondents reported that they had a good care at the center. While, a minority (3.8%) recorded that the center's services were poor. The users illustrated that the health care services and health care providers were the best items in the center, 53.9% and 46.0%, respectively. The cheap services were considered the commonest cause of satisfaction as reported by 47.9% of females and 53.0% of males. While, drug deficiency was the commonest cause of dissatisfaction as mentioned by 73.0% of females and 55.9% of males. Conclusion: The majority of our respondents were relatively satisfied regarding different aspects of care. However, still there are many efforts (e.g. drug adequacy) needed for improvement of patient satisfaction. Recommendation: Health authorities should paid attention to overcome causes related to utilizers' dissatisfaction as drug unavailability.
