Aim: To explore the way in which Latin American psychiatrists approach the screening of vascular risk factors in patients receiving antipsychotic medication.
Methods: This was a descriptive, cross sectional study that surveyed Latin-American physicians to evaluate differences between groups divided in three main sections. The first section included demographic and professional data. The second section asked about the available medical resources: weighing scales, sphygmomanometer and measuring tape. Finally, the third section aimed at looking into the attitudes towards cardiovascular prevention. The latter was also divided into two subsections. In the first one, the questions were about weight, blood pressure and waist perimeter. In the second subsection the questions asked about the proportion of patients: (1) that suffered from overweight and/or obesity; (2) whose lipids and glycemia were controlled by the physician; (3) that were questioned by, and received information from the physician about smoking; and (4) that received recommendations from the physician to engage in regular physical activity. The participants were physicians, users of the medical website Intramed. The visitors were recruited by a banner that invited them to voluntarily access an online self-reported structured questionnaire with multiple options.
Results: We surveyed 1185 general physicians and 792 psychiatrists. Regarding basic medical resources, a significantly higher proportion of general physicians claimed to have weighing scales (χ(2) = 404.9; P < 0.001), sphygmomanometers (χ(2) = 419.3; P < 0.001), and measuring tapes (χ(2) = 336.5; P < 0.001). While general physicians measured overweight and metabolic indexes in the general population in a higher proportion than in patients treated with antipsychotics (Z = -11.91; P < 0.001), psychiatrists claimed to measure them in patients medicated with antipsychotics in a higher proportion than in the general population (Z = -3.26; P < 0.001). Also general physicians tended to evaluate smoking habits in the general population more than psychiatrists (Z = -7.02; P < 0.001), but psychiatrists evaluated smoking habits in patients medicated with antipsychotics more than general physicians did (Z = -2.25; P = 0.024). General physicians showed a significantly higher tendency to control blood pressure (χ(2) = 334.987; P < 0.001), weight (χ(2) = 435.636; P < 0.001) and waist perimeter (χ(2) = 96.52; P < 0.001) themselves and they did so in all patients. General physicians suggested physical activity to all patients more frequently (Z = -2.23; P = 0.026), but psychiatrists recommended physical activity to patients medicated with antipsychotics more frequently (Z = -7.53; P < 0.001).
Conclusion: Psychiatrists usually check vascular risk factors in their patients, especially in those taking antipsychotics. General practitioners check them routinely without paying special attention to this population.
