Impacts of a health literacy-informed intervention in people with chronic obstructive pulmonary disease (COPD) on hospitalization, health literacy, self-management, quality of life, and health costs - A randomized controlled trial.

OBJECTIVE: To compare the effect of motivational interviewing (MI) and tailored health literacy (HL) follow-up with usual care on hospitalization, costs, HL, self-management, Quality of life (QOL), and psychological stress in people with chronic obstructive pulmonary disease (COPD). METHODS: A RCT was undertaken in Norway between March 2018-December 2020 (n = 127). The control group (CG, n = 63) received usual care. The intervention group (IG, n = 64) received tailored HL follow-up from MI-trained COPD nurses with home visits for eight weeks and phone calls for four months after hospitalization. Primary outcomes were hospitalization at eight weeks, six months, and one year from baseline. The trial was registered with ClinicalTrials.gov (NCT03216603) and analysed per protocol. RESULTS: Compared with the IG, the CG had 2.8 higher odds (95% CI [1.3 to 5.8]) of hospitalization and higher hospital health costs (MD=€ -6230, 95% CI [-6510 to -5951]) and lower QALYs (MD=0.1, 95% CI [0.10 to 0.11]) that gives an ICER = - 62,300. The IG reported higher QOL, self-management, and HL (p = 0.02- to <0.01). CONCLUSION: MI-trained COPD nurses using tailored HL follow-up is cost-effective, reduces hospitalization, and increases QOL, HL, and self-care in COPD. PRACTICE IMPLICATION: Tailored HL follow-up is beneficial for individuals with COPD and the healthcare system.

Effects of guided deep breathing on breathlessness and the breathing pattern in chronic obstructive pulmonary disease: a double-blind randomized control study.

OBJECTIVE: To investigate whether guided deep breathing using a device improves breathlessness, quality of life, and breathing pattern in moderate and severe stage of chronic obstructive pulmonary disease (COPD). METHODS: In total, 150 patients participated in a double-blind randomized controlled trial in a four-week intervention and a four-month follow-up. Participants were randomized into a guided deep breathing group (GDBG), music listening group (MLG), or sitting still group (SSG). The patients' symptom score using the St George's Respiratory Questionnaire (SGRQ), and a Global Rating Change scale (GRC) was applied to measure breathlessness as primary outcome. The activity score and impact score of SRGQ, and breathing pattern were secondary outcomes. RESULTS: Positive effects of the GDBG were detected in GRC scale in breathlessness at four weeks (p=0.03) with remaining effect compared to MLG (p=0.04), but not to SSG at four months follow-up. GDBG showed positive effect for respiratory rate (p<0.001) at four weeks follow-up. A positive significant change (p<0.05-0.01) was found in all groups of SGRQ symptom score. CONCLUSION: GDBG had a beneficial effect on respiratory pattern and breathlessness. MLG and SSG also yielded significant improvements. PRACTICE IMPLICATIONS: Guided deep breathing may be used as a self-management procedure.
