Anemia and its predictors among patients on hemodialysis, at Felege Hiote Referral Hospital, Northwest Ethiopia, 2022: a retrospective cohort study.

BACKGROUND

Anemia is a critical complication among hemodialysis patients, often leading to poor outcomes. This study aimed to assess anemia prevalence and identify predictors among hemodialysis patients at Felege Hiote Referral Hospital, Northwest Ethiopia, in 2022.

RESEARCH DESIGN AND

METHODS

A retrospective cohort study analyzed 410 hemodialysis patients from January 2018 to February 2022. Data was collected from medical records, entered using Epi-data Version 4.1, and analyzed with STATA Version 14. Kaplan-Meier survival curves assessed survival time, while Cox regression identified anemia predictors.

RESULTS

Of 410 patients, 66 (16.1%) developed anemia, with an incidence rate of 7.9 per 100 person-years (95% CI: 3.1-13.5). Significant predictors included female sex (IRR: 1.5, p = 0.04), rural residence (IRR: 2.5, p = 0.01), low body mass index (IRR: 1.6, p = 0.02), and congestive heart failure (IRR: 6.9, p = 0.02).

CONCLUSIONS

Anemia prevalence among hemodialysis patients is high, with key predictors including gender, residence, body mass index, and comorbidities. Interventions targeting these factors, especially in rural areas, could reduce anemia incidence. Study limitations include single-center data, incomplete variables, and lack of causality.
