Abstract

Background: Patients experience substantial morbidity following discharge from hospital and during recovery from community-acquired pneumonia (CAP). Inspiratory muscle training (IMT) has demonstrated improved functional capacity and reduced patient-reported symptoms. To date the safety and tolerability of these methods have not been determined in CAP patients recovering following hospitalization. Accordingly, this study aimed to assess the safety and tolerability of IMT in adults discharged from hospital with CAP.

Methods: Participants received an IMT device (POWERbreathe KHP2) and completed 9-weeks IMT training with weekly follow-up. Frequency (twice daily) and load (50% PImax) were fixed throughout, but training volume increased incrementally (2-week habituation phase, 7-week training phase). Primary outcomes of interest included IMT safety and tolerability.

Results: Twenty-two participants were recruited; 16 were male, mean age 55.2years (range 27.9-77.3). From 1183 possible training days, side effects were reported on 15 occasions by 10 individual participants. All reported side-effects were assessed as grade 1 and did not prevent further training. Participant-reported IMT acceptability was 99.4%.

Conclusion: Inspiratory Muscle Training is safe and tolerable in patients following hospitalisation for CAP. Patient satisfaction with IMT is high and it is viewed by patients as being helpful in their recovery. Distinguishing CAP-related symptoms and device-related side effects is challenging. Symptom prevalence declined during follow-up with concurrent improvements in spirometry observed. Further research is required to determine the efficacy of IMT interventions following CAP and other acute respiratory infections.?
