[Healthcare professionals' knowledge of blood pressure measurement].

This study investigated the theoretical and technical knowledge of blood pressure measurement from 110 nursing assistants, 44 physicians and 25 nurses by answering to a questionnaire and practical knowledge through the observation of the blood pressure measurement procedure. In the theoretical knowledge the three categories showed statistically significant differences (p<0,05), the nursing assistants showed a lower indicator of the correctness (32%+/-12%) followed by nurses (44%+/-14%) and physicians (56%+/-13%). In the practical knowledge the physicians showed higher percentage of correctness (50%+/-12%) (p<0.05);followed by nurses (44%+/-10%) and nursing assistants (41%+/-6%). In conclusion, the knowledge of blood pressure measurement was not satisfactory.
