OBJECTIVE: To examine whether simple interventions in a sickle cell clinic improve survival in sickle cell disease. DESIGN: Survival curve analysis and hazard ratios in a cohort study followed from birth. SETTING: MRC Laboratories (Jamaica) at the University of the West Indies, and Victoria Jubilee Hospital, Kingston, Jamaica. SUBJECTS: 315 patients with homozygous sickle cell disease detected during the screening of 100,000 consecutive non-operative deliveries between June 1973 and December 1981 at the main government maternity hospital, Kingston, Jamaica. INTERVENTIONS: Prophylactic penicillin to prevent pneumococcal septicaemia, parental education in early diagnosis of acute splenic sequestration, close monitoring in sickle cell clinic. MAIN OUTCOME MEASURES: Survival. RESULTS: Survival appeared to improve, the log rank test for trend comparing the first, second, and last third of the study reaching borderline significance (P = 0.05). Combined deaths from acute splenic sequestration and pneumococcal septicaemia-meningitis declined significantly (test for trend, P = 0.02). CONCLUSION: Early diagnosis and simple prophylactic measures significantly reduce deaths associated with homozygous sickle cell disease.
