Reporting Inpatients' Experiences and Satisfaction in a National Psychiatric Facility: A Study Based on the Random Forest Algorithm.

Understanding psychiatric inpatients' experiences is important to establish a culture of patient-centric care and promote trust in healthcare. This study aimed to evaluate nine dimensions of patients' experiences and investigate their association with patient satisfaction, revisit intention, and positive word-of-mouth (WoM) recommendation. Cross-sectional questionnaire data from five years of surveying (2016-2020) in the main psychiatric hospital in Bahrain were statistically analyzed, involving 763 psychiatric inpatients with an overall 65.6 ± 17.2 length of stay (days). The findings show that across the five years 2016-2020, the overall reported satisfaction was "very high" (4.75 ± 0.44) with no significant differences between these five years (F [4, 758] = 0.66,  = 0.620). The experience of confidentiality received the highest rating (4.72 ± 0.45). The experiences of ease of access, hospitality quality, and quality of responsiveness to one's needs significantly correlated with revisit intention ( ˂ 0.05). Patients with high satisfaction had greater potential for revisit intention (r [761] = 0.08,  = 0.027), which was associated with WoM recommendation (r [761] = 0.08,  = 0.033). Overall, men were less likely than women to experience convenient access to psychiatric wards. The findings of the Random Forest algorithm indicate the tendency of female patients with short-term stays to demonstrate lower satisfaction rates, and thus innovative approaches are needed when managing these groups' psychiatric problems.
