Rationale, aims and objectives

Several health information sources are available to assist physical therapists in the clinical decision-making process, with a notable increase in the importance of using evidence-based practice (EBP). The aim of this study is to investigate the health information sources most used by Brazilian physical therapists to guide their clinical decision making for knee osteoarthritis (OA) management, use of Physiotherapy Evidence Database (PEDro), knowledge about the existence of clinical practice guidelines (CPGs), and associated factors.

Methods

A cross-sectional study using an electronic survey was conducted. Physical therapists registered in a Regional Physical Therapy Council in Brazil were invited to participate. Sociodemographic data, professional training, health information sources, frequency of use of PEDro, and knowledge about CPGs were collected. Descriptive analysis of the data was performed, and the chi square test and multinomial and binary logistic regression were used to verify association between the variables.

Results

The survey was completed by 370 professionals. The three health information sources most used by Brazilian physical therapists were clinical experience, courses, and books. Among these professionals, only 12.1% use PEDro frequently, and 60.5% know that CPGs for knee OA management exist. Level of education was associated with PEDro use and knowledge about the existence of CPGs (P < .05).

Conclusions

The study results indicated a significant deficiency in engagement with research evidence by Brazilian physical therapists to guide their clinical decision making for knee OA. Further investigations on educational needs and the development of new strategies to narrow the gap between research evidence and clinical practice should be performed.
