Effects of enhanced education for patients with the Helicobacter pylori infection: A systematic review and meta-analysis.

BACKGROUND

Helicobacter pylori (H. pylori) infections are of serious concern due to the associated risk of gastric cancer. However, many patients have poor medication and therapy compliance, which makes it difficult to eradicate their infections. This points to the need for stronger educational interventions aimed at enhancing compliance, thus increasing the potential for treatment success. As such, this study conducted a meta-analysis to clarify the effects of enhanced patient education (EPE) programs for H. pylori.

MATERIALS AND

METHODS

We searched electronic databases (PubMed, EMBASE, Web of Science, and Cochrane Library) for randomized controlled trials (RCTs) on health education for patients infected with H. pylori from inception to June 2021. The primary outcome was the eradication rate of H. pylori, while the secondary outcomes included the incidence of individual adverse symptoms, treatment compliance, clinical symptom remission after treatment, and patient satisfaction. We used the fixed or random-effects model to pool the risk ratio (RR), with 95% confidence interval. We also conducted sensitivity and subgroup analyses.

RESULTS

Our search returned seven relevant studies across a total of 1,433 patients. Compared with controls, EPE was significantly associated with improved H. pylori eradication rates (RR = 1.16, 95%CI: 1.04-1.29, p = 0.006) and patient compliance (RR = 1.48, 95%CI: 1.14-1.93, p = 0.003). A subgroup analysis also showed that EPE benefits were consistent across patients with different eradication programs, WeChat intervention plans, and intervention frequencies (p < 0.05). However, there were no significant differences in the total adverse effects, common side effects (diarrhea, nausea, abdominal pain, taste disorder, and skin rash), or discontinuation rate (p > 0.05).

CONCLUSIONS

Patient education is inexpensive, safe, and convenient. In this context, our findings suggest that enhanced educational interventions have positive effects on both the H. pylori eradication rate and adherence among infected patients, and thus constitute promising complements to clinical treatment regimens.
