ObjectiveThis study aimed to determine the level of adherence to foot care recommendations and associated factors among people with diabetes on follow-up in public hospitals in Eastern Ethiopia.SettingAn institutional-based cross-sectional study was conducted in public hospitals found in Eastern Ethiopia from 25 February to 25 March 2022.ParticipantsA total of 419 patients with chronic diabetes who visited diabetic clinics in public hospitals in Eastern Ethiopia for follow-up were included.Main outcome measureThe level of adherence to diabetic foot care recommendations and associated factors.ResultsThe findings indicated that 44.3% (95% CI: 39.3, 49.0) of people with diabetes had inadequate adherence to diabetic foot care recommendations. Age between 28–37 (adjusted OR (AOR)=1.10; 95% CI: 1.27, 5.63) and 38–47 years (AOR=2.19; 95% CI: 2.74, 8.89), rural residence (AOR=1.71; 95% CI: 1.15, 2.57), absence of comorbidity (AOR=2.22; 95% CI:1.34, 5.14), obesity (AOR=1.43; 95% CI: 1.10, 5.05) and inadequate foot care knowledge (AOR=2.10; 95% CI: 1.52, 4.35) were factors significantly associated with inadequate adherence to diabetic foot care recommendations.ConclusionMore than two-fifths of people with diabetes had inadequate adherence to diabetic foot care recommendations. Younger age, rural residence, absence of comorbidity, obesity and inadequate foot care knowledge were significantly associated with inadequate adherence to diabetic foot care recommendations. It is very essential to educate people with diabetes about the importance of foot care recommendations in preventing and delaying the risks of foot-related problems and complications.
