[Prescription of antidepressants in primary care: a descriptive study on medical professionals' confidence]

Antidepressants are the third most prescribed drug class, and most prescriptions are not performed by specialists. This study aimed to evaluate primary health care (PHC) physicians' self-perceived confidence in prescribing antidepressants. This is a cross-sectional study with PHC physicians in the municipality of Salvador, Bahia State, Brazil. Psychiatrists or psychiatry residents were excluded. The self-assessment of confidence and the collection of participants' characteristics was carried out by an online questionnaire. Categorical variables were presented in absolute and relative frequencies. Continuous variables were described as means or medians according to their normality distribution. Of 447 physicians, the sample consisted of 55 participants. Their mean age was 37.2 ± 12.8 years. Most physicians (75%) claimed confidence in prescribing antidepressants. Self-perceived confidence remained predominant in scenarios with older adults (69.2%) and patients with general comorbidities (65.4%). A minority showed confidence to prescribe antidepressants to children/adolescents (19.2%) and pregnant women (26.9%). For 80.4% of participants, selective serotonin reuptake inhibitors were the most trusted pharmacological class. Referral to the Psychosocial Care Center was the most reported strategy in cases of insecure prescription (32%). To the best of our knowledge, this is the first study to address such an issue. Thus, it can contribute to more assertive health education actions for PHC physicians.
