Effectiveness of a telenursing intervention program in reducing exacerbations in patients with chronic respiratory failure receiving noninvasive positive pressure ventilation: A randomized controlled trial.

Telenursing for patients with chronic respiratory failure receiving noninvasive positive pressure ventilation (NPPV) is an important aid in reducing exacerbations; however, there is insufficient evidence. This randomized controlled trial investigated the effectiveness of a telenursing intervention program in reducing exacerbations in patients with chronic respiratory failure receiving NPPV at home. We included patients receiving NPPV at home who could handle a tablet device. The intervention group (n = 15) underwent an information and communications technology-based telenursing intervention program in addition to usual care; the control group (n = 16) received the usual care only. The telenursing intervention program comprised telemonitoring and health counseling sessions via videophone. The intervention was evaluated once at enrollment and after 3 months. The primary endpoints were the number of unscheduled outpatient visits, hospitalizations, and hospital days. The secondary endpoints included the St. George's Respiratory Questionnaire (SGRQ) score, Euro QOL 5 Dimension score, Self-Care Agency Questionnaire (SCAQ) score, pulmonary function tests, and 6-min walking distance. We used the Mann-Whitney U test for our analysis. We found no significant differences between the intervention and control groups at enrollment. Then, the differences between the endpoints at baseline and 3 months after enrollment were calculated and used to compare both groups. At follow-up, the number of routine outpatient visits for acute exacerbations (p = .045), the number of hospitalizations (p = .037), the number of hospital days (p = .031), SGRQ (p = .039) score, and SCAQ (p = .034) score were significantly different. The increase in the number of unscheduled outpatient visits in the intervention group during follow-up was attributed to acute exacerbations and a significant decrease in the number of hospitalizations and hospital days. Hence, the telenursing intervention program may be effective in reducing exacerbations in patients with chronic respiratory failure receiving NPPV at home.
