A survey on the performance of the six-minute walk test

Objective.- To ascertain, through a national survey, whether the performance of the six-minute walk test (MW6) is in accordance with the recommendations of the American thoracic society (ATS). Methods.- An anonymous questionnaire was sent electronically to 206 departments of respiratory medicine (39 teaching hospitals and 167 general hospitals) and to respiratory rehabilitation departments provided by the Alveolar group of the SLPF (French language respiratory society), and then distributed on a discussion site specialising in respiratory physiotherapy and a professional information site for physiotherapists. Results.- One hundred and eleven questionnaires were returned between October 2009 and April 2010, 105 from France. The response rate from hospitals was 30%. The MW6 was performed mainly by physiotherapists and nurses. In 48% there was no precise time for its performance. The site used was a corridor longer than 30 metres in 52% of cases. In 60% the patient was accompanied by the observer. In 35% a familiarisation test was performed, with a delay of 30 minutes or less between the two tests in 62% of these. In 40% encouragement was given. SpO(2) was monitored during the MW6 in 95%. Conclusion.- For many items the recommendations of the ATS are not followed. The differences found were mainly due to constraints on the services (availability of operators and/or patients). (C) 2011 SPLF. Published by Elsevier Masson SAS. All rights reserved.
