Evidence-Based Practice: a survey regarding behavior, knowledge, skills, resources, opinions and perceived barriers of Brazilian physical therapists from São Paulo state

BACKGROUND Evidence-Based Practice (EBP) has been widely used by health professionals. However, no study in Brazil has investigated the data regarding the knowledge and difficulties related to EBP from a representative sample of physical therapists. OBJECTIVE To identify behavior, knowledge, skills, resources, opinions and perceived barriers of Brazilian physical therapists from the state of São Paulo regarding EBP. METHOD A customized questionnaire about behavior, knowledge, skills, resources, opinions and perceived barriers regarding EBP was sent by email to a sample of 490 physical therapists registered by the Registration Board of São Paulo, Brazil. Physical therapists who did not respond to the questionnaire were contacted by telephone and/or letter. The data were analyzed descriptively. RESULTS The final response rate was 64.4% (316/490). Because 60 physical therapists were no longer practicing, 256 answers were analyzed. The physical therapists reported that they routinely read scientific papers (89.5%) as a resource for professional development, followed by continuing education courses (88.3%) and books (86.3%). Approximately 35% of the respondents reported a clear understanding of the implementation of research findings in their practice; approximately 37% reported no difficulties in critically appraising scientific papers; and 67.2% strongly agreed that EBP is important for their practice. The most commonly reported barriers were related to difficulties in obtaining full-text papers (80.1%), using EBP may represent higher cost (80.1%) and the language of publication of the papers (70.3%). CONCLUSION Physical therapists from São Paulo state believe that they have knowledge and skills to use EBP. Although they have favorable opinions regarding its implementation, they still encounter difficulties in implementing EBP successfully.
