Primary Health Care (PHC) service management is one of the most important job opportunities for Public Health (PH) specialists. Despite this, according to a previous needs assessment survey, the topic of PHC is not included in the educational programs of 70% of specialization schools in PH in Italy and more than 80% of PH residents declare to have very little acquaintance with PHC. In march 2022, an online series of eight lectures was organized to standardize the level of knowledge and increase awareness of this field. This study aimed to evaluate the impact of these lectures. More than 900 PH residents attended the lessons. After the lectures, a questionnaire was administered. It consisted of 4 sections: general organization, speakers’ competence, acquired knowledge and overall opinion. In each question participants had to indicate a score from 1 to 5 (likert scale) based on their satisfaction. Chi-square tests were performed to compare results from different groups. A total of 410 PH residents from each Italian region (north 51%, center 21%, south 28%) answered the questionnaire. 92% of participants assigned a high global score (≥ 4), 68% assigned a score ≥ 4 to the acquired knowledge. Residents in their iii or iv years of school, compared with those in their i or ii, considered the competencies acquired transferrable in their working context (p=0.040). Residents in their i and ii years were more interested in additional lessons (p=0.041). Overall opinion was not different between those who followed the lessons voluntarily or mandatorily (p>0.05). This series of conferences has increased perceived knowledge and awareness of PHC issues. These results suggest that it is possible to think of homogeneous and standardized training courses that PH residents can attend in synchrony from all over the country.
