Results
A total of 926 patients were screened for participation in the study; 546 did not meet the inclusion criteria. Of those eligible to take part in the study, 228 refused to participate while the rest (152 patients) were enrolled in the study and randomized equally into control and intervention groups. No significant differences were initially observed between the two groups in their sociodemographic/clinical characteristics. After three months 103 patients (67%) returned for follow-up and their data included in the final analysis; 52 (50.5%) were in the control group (verbal TTG), 51 (49.5%) in the intervention group (video-based TTG). No significant differences were observed in the sociodemographic/clinical characteristics between the patients included in the final analysis (patients followed up, N = 103) and those that dropped out from the study (N = 49).
