BACKGROUND: Conventional chest physical therapy (CPT) has become the standard to which all other bronchial hygiene techniques are compared. The objective of this investigation was to compare the clinical outcomes of hospitalized patients treated with The Vest® Airway Clearance System (the Vest®) vs. CPT. METHODS: Hospitalized patients prescribed CPT were randomized to receive therapy consisting of the Vest® or conventional CPT. The Vest® facilitates removal of secretions from the lungs utilizing an air pulse generator and an inflatable vest to create high frequency chest wall oscillation (HFCWO). The primary outcome measure was the number of hospital free days. Hospital free days are defined as the number of days free from hospitalization during the study enrollment period [30 days]. A patient satisfaction rating, as measured by using a comfort scale, was a secondary outcome measure. RESULTS: This is an interim analysis of an ongoing study. Ninety-eight patients completed the study so far. The Vest® group (n = 46) and the CPT group (n = 52) had no significant differences in their baseline characteristics at the time of entry into the study. There was no significant difference in the number of hospital free days between the Vest® group and the CPT group (18.7 ± 8.8 days vs. 19.8 ± 7.6 days, respectively; p = 0.50). There was also no significant difference in patient satisfaction ratings (2.1 ± 0.7 vs. 2.2 ± 0.7, respectively; p = 0.66). CONCLUSIONS: This interim analysis shows no statistical difference between the Vest® and CPT group when comparing primary outcomes of hospital free days and patient satisfaction.
