Barriers to participation in these strategies is also described. Results: In the 2021-2023 period, 23 trainings were conducted with 384 participants, as well as two workshops with 134 participants, six rounds of awareness-raising with 242 professionals, 2 486 rounds of active searches twice a week in both sentinel hospitals, and an instant messaging system with 157 participants. The questionnaire obtained 154 responses from health workers. The main barriers were not realizing the questionnaire existed, limited availability of time, and no staff to replace them in the wards.
