Improved Patient Adherence to Family‐Based Helicobacter pylori Infection Control and Management Strategy in Central China and Its Influencing Factors

ABSTRACT Background Patient adherence status to the newly introduced family‐based Helicobacter pylori ( H. pylori ) infection control and management strategy remains unclear, so are its influencing factors. We aim to investigate family members' adherence and its influencing factors during the family‐based H. pylori infection management practice for related disease prevention. Materials and Methods Based on our previously family‐based H. pylori survey in 2021, 282 families including 772 individuals were followed up 2 years after the initial survey to compare if the investigation and education might improve family member's adherence. The participant's adherence to H. pylori infection awareness, retest, treatment, publicity, gastroscopy, and hygiene habits were followed up, and their influencing factors were also analyzed. Results The overall participant's adherence to recommendations on H. pylori awareness, retest, treatment, publicity, gastroscopy, and hygiene habits were 77% (187/243), 67.3% (138/205), 60.1% (211/351), 46.5% (107/230), 45.6% (159/349), and 39.1% (213/545), respectively; and all showed improvements compared with their prior survey stages. The top reasons for rejection to treatment, retest, and gastroscopy were forgetting or unaware of H. pylori infection (30.3%), busy (32.8%), and asymptomatic (67.9%), respectively. Independent risk factor for low adherence to treatment was occupation (e.g., staff: OR 4.49, 95% CI 1.34–15.10). Independent favorable factors for treatment adherence were individuals at the ages of 18–44 years (OR 0.19, 95% CI 0.04–0.89) and had a large family size (e.g., four family members: OR 0.15, 95% CI 0.06–0.41); for retest adherence, it was individuals at the ages of 60–69 years (OR 0.23, 95% CI 0.06–0.97); for gastroscopy adherence, it was individuals at the age of 60–69 years (OR 0.46, 95% CI 0.28–0.75), and with gastrointestinal symptoms (OR 0.57, 95% CI 0.36–0.90). Conclusions Family‐based H. pylori management increases individual adherence to treatment, retest, and awareness, and there are also improved adherence to gastroscopy, publicity, and personal hygiene recommendations; further efforts are required to enhance the individual adherence rate for related disease prevention.
