The aim of this study was to identify the most important factors associated with undergraduate students' decisions to enroll in the health informatics program at Hail University in Saudi Arabia. A cross-sectional survey was conducted among the population of 73 students (second to fourth year; 52 females, 21 males; age range 19-25 years). A hierarchy of perceived sources of influence was identified. Counselors, teachers and other professionals, and promotional materials, including information in the media, as well as the high quality characteristics of the institution, had the strongest influence. Other students, friends and family, the academic reputation of the University and the health informatics department faculty, together with interactions in the academic environment (e.g. segregation by gender) and financial, job, career, and postgraduate opportunities, were perceived to be weaker sources of influence. The strengths of the sources of influence varied significantly with respect to the socio-demographic characteristics of the students, as well as the categories associated with the decision-making process. Strong sources of influence were particularly important for the increasing number of female students who often made the final decision to enroll. These findings will support policy and decision makers to make better plans for health informatics education by understanding the influential sources that attract students into the health informatics profession, and will also assist the health care sector's attempts to avoid a deficiency in this rapidly expanding professional field.
