Pulmonary rehabilitation in private practice: trial supports feasibility, but not yet comparative effectiveness

A trial focused on whether participants could complete the programme

The study included 55 participants, of whom 52 were randomly assigned to either a pulmonary rehabilitation programme or usual care. The programme involved two sessions per week for eight weeks, delivered in private practices.

The primary outcome was not an improvement in breathing or walking, but the proportion of participants who completed the intervention. Among those assigned to the programme, 75% completed it. The researchers also assessed exercise capacity, health status and quality of life at baseline and after eight weeks.

Improvements observed, without a clear comparison between groups

Among participants who undertook the programme, incremental shuttle walk test distance increased by an average of 53.7 metres, with a 95% confidence interval of 37.8 to 69.6 metres. The number of sit-to-stand repetitions completed in one minute increased by an average of 4.7, with an interval of 3.3 to 6.0 repetitions.

Respiratory health questionnaire scores also improved. According to the authors, the observed changes exceeded the minimum thresholds for improvement considered important for these measures.

The key distinction is that these results describe before-and-after changes in people who undertook the intervention. The abstract does not report a numerical difference between groups. In addition, some participants assigned to usual care ultimately undertook the programme for logistical reasons, blurring the planned comparison.

A potential approach to care delivery, not a do-it-yourself protocol

Only one minor study-related adverse event was reported. This is a reassuring signal in this sample, but a trial of this size and duration is not sufficient to rule out rare adverse effects.

The main contribution therefore concerns care delivery: these practices could provide an additional setting for supervised pulmonary rehabilitation. However, the study does not demonstrate that this approach actually increases access at a population level, or that the improvements persist beyond eight weeks.

What we can take away

This trial supports the feasibility of delivering pulmonary rehabilitation in private practice. The observed improvements are encouraging, but their magnitude relative to usual care remains to be clarified.
