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.

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). 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. 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). MI-trained COPD nurses using tailored HL follow-up is cost-effective, reduces hospitalization, and increases QOL, HL, and self-care in COPD. Tailored HL follow-up is beneficial for individuals with COPD and the healthcare system. • People with COPD have higher rates of hospitalizations and health literacy (HL) challenges. • They need follow-up in HL, understanding, accessing, using and remembering health information. • The specialists- and community healthcare should collaborate, and HL be tailored to the individual. • Healthcare professionals need strategies such as motivational interviewing to use in follow-up to improve HL. • Tailored HL follow-up affects hospitalization rate, cost, HL, self-management, and quality of life.
