Fatores preditivos para a cicatrização de úlceras da perna em pessoas com doença falciforme: coorte retrospectivo

Abstract

Objective: to identify the healing rate and predictive factors for healing of leg ulcers in people with sickle cell disease. Method: retrospective cohort, carried out from June to August 2020, in a specialized service for the treatment of people with wounds, covering a period of nine years, with a sample of 52 ulcers that met the eligibility criteria. Research protocol approved by the ethics committee. Results: healing rate was 76.9%. The factors that contributed to cure in a shorter time were non-recurrence (HR= 3.03; 95% CI: 1.07-8.60) and extension below the median 7.25 cm2 (HR= 2.25; CI 95%: 1.19-4.27). Factors for non-healing were: calcium alginate dressings (HR=0.29; 95% CI: 0.13-0.62), charcoal with silver (HR=0.06; 95% CI: 0.02- 0.21) and others (HR=0.35; 95% CI: 0.15-0.80). Conclusion: the ulcer healing rate was high. Recurrence, ulcer area and certain dressings can influence the healing process.
