Abstract The objective of the research is to determine the incidence of waiting time for consultation and appointment scheduling on the satisfaction of users of the facilities of the Ministry of Health (MINSA) and Social Health Insurance (ESSALUD). The research methodology is quantitative of causal type, using the Ordered Logit model, with a sample of 3,644 users of the Ministry of Health and 1,211 users of the Social Health Insurance from the National Household Survey (ENAHO). The probability of satisfaction among MINSA users is 82% with an average waiting time of 41 minutes and 0.7 days to schedule an appointment, while for ESSALUD satisfaction is 75% with 56 minutes of waiting time for a consultation and 6.8 days to obtain a medical appointment. The probability of satisfaction in both facilities decreases for every 10 minutes of waiting time for consultation and for every additional day of waiting time to obtain a medical appointment. Dissatisfaction is even worse after 60 minutes, and it is also observed that patients in the extreme poor and non-extreme poor groups reveal greater satisfaction than those in the non-poor groups. Patients spend more time waiting to be attended in the doctor's office and to obtain a medical appointment than consulting with health professionals. Keywords: Scheduled appointment; medical consultation; health facilities and probability of satisfaction. Introduction Waiting time for appointment scheduling or consultation care is a frequent problem in health facilities in the Ministry of Health (MINSA) and Social Health Insurance (ESSALUD), which can trigger user complaints and dissatisfaction. Long patient waits have attracted increasing public attention due to the negative effects of waiting time on patients' satisfaction with medical care (Xie & Or, 2017). Waiting time is considered an important factor in determining quality of care, which may represent a valuable tool for assessing patient satisfaction (Harajin et al., 2019). Patient satisfaction is a performance indicator that measures the extent to which the patient is happy and satisfied with the level of care provided by healthcare institutions and providers (Alrasheedi et al., 2019). It is also based on individuals' experiences and needs with respect to
