“…For our research purpose though, only hospitalized patients from 13 clinics were included in our study: Internal medicine (two clinics), Cardiology, Neurology, Nephrology, Oncology, General surgery (two clinics), Gynecology, Ophthalmology, Orthopedics, Plastic surgery and Urology). The study was designed to recruit a representative cross section of each one of the 13 clinics with equal numbers of subjects recruited in each one of six design cells that were defined by age (18-40, 41-60, 61-80 years old) and gender, in order to avoid sampling bias, given that these two demographic factors have been repeatedly associated with patient-centered attitudes in previous studies [5][6][7]9]. To ensure sufficient representation, target numbers for each clinic were identified by reviewing the distribution of patients across the clinics within one typical month.…”
