Gender differences in the impact of health literacy on hospital readmission among older heart failure patients: A prospective cohort study

초록

Aims To investigate the impact of limited health literacy on 1-year hospital readmission among both older men and women with heart failure. Design Prospective cohort study. Methods A total of 286 patients with heart failure (men = 144, women = 142) aged 65 years or older at baseline from two tertiary hospitals were enrolled from June-November 2017. Patients were followed up until November 2018. The Brief Health Literacy Screening Tool was used to assess baseline health literacy. One-year readmission after discharge was assessed via medical records or telephone interview. A hierarchical logistic regression was performed. Results The prevalence rates of limited health literacy and 1-year hospital readmission among older women were 74.7% and 35.9%, respectively, compared with 48.6% and 27.1% in older men. Limited health literacy significantly increased the risk of 1-year hospital readmission in both older men and women with heart failure. More importantly, older women with limited health literacy had a much higher risk of hospital readmission (odds ratio: 10.17, 95% confidence interval: 2.19-47.14) than did older men with limited health literacy (odds ratio: 5.27, 95% confidence interval: 2.04-13.59). Conclusions Our findings highlight that a baseline assessment of health literacy would help prevent unplanned hospital readmissions after discharge in both older men and women with heart failure. Health professionals should recognize that women with limited health literacy are more vulnerable to re-hospitalization than are men with limited health literacy. Impact Few studies have addressed gender differences in the link between health literacy and hospital readmission among patients with heart failure. We found that older women with limited health literacy had a much higher risk of hospital readmission than did their male counterparts. Health professionals should be aware of gender differences in health literacy in discharge planning, including self-management counselling for older patients with heart failure.
