Results: Of 120 respondents, 27.5% reported satisfaction. Female sex (RPa: 0.57, IC95%: 0.32-0.99), young (RPa: 0.33, IC95%: 0.19-0.60), adult (RPa: 0.33, IC95%: 0.19-0.60), older adult (RPa: 0.46, 95% CI: 0.28-0.76) and having SIS insurance (RPa: 0.68, 95% CI: 0.57-0.81) were negatively associated to satisfaction. Being treated in gynecology-obstetrics (RPa: 2.15, IC95%: 1.06-4.35), general medicine-specialties (RP: 1.58, IC95%: 1.38-1.81), and being a user (PR: 2.11, IC95%: 1.34-3.33) was positively associated with satisfaction.
