Knowledge among nephrologists about the importance of exercise in the intradialytic period

[Purpose] To assess knowledge among nephrologists at hemodialysis services about routine intradialytic therapeutic exercise, in the city of Recife. [Subjects and Methods] A cross-sectional study, consisting of 49 nephrologists working in public and/or private hemodialysis services, who responded to a semi-structured questionnaire about their academic background, medical residency, and knowledge about exercise during the intradialytic period. [Results] About 56.3% practiced for more than 10 years as nephrologists, 69.4% did not receive information about intradialytic physical exercise while in residency, 81.6% considered intradialytic exercise to be important, and 53.0% did not prescribe exercise during hemodialysis. About 61.2% consider the level of physical activity among their patients to be poor. Nephrologists graduating within 2 years were 10 times more likely to prescribe exercise, compared to those with more than 2 years since graduation. [Conclusion] Our study found that the nephrologists interviewed do not usually prescribe intradialytic therapeutic exercise, despite understanding its importance as part of the treatment process. It is necessary to update doctors about the importance of exercise for patients during the intradialytic period, as well as to incorporate this knowledge at the undergraduate level.
