The development of sickle cell clinics in Jamaica over a 30-year period is reviewed. The clinics are expanding almost exponentially, new cases of SS disease being recruited at approximately 150 per year and new cases of SC disease at approximately 60 per year. In the first 20 years, the median age of clinic attenders increased markedly but has remained stable since 1970. This stable age structure in the presence of an almost exponential rate of clinic expansion implies that the influx of young cases is balanced by the increasing age of existing clinic attenders. The pattern of new referrals has also changed to that of predominantly young patients, suggesting that the bulk of symptomatic older patients in the community have already been recruited into the clinic population.
回顾了牙买加30年来镰状细胞诊所的发展情况。诊所几乎呈指数级扩张，每年新增SS病病例约150例，新增SC病病例约60例。在最初的20年里，诊所就诊者的年龄中位数显著增加，但自1970年以来一直保持稳定。在诊所几乎呈指数级扩张的情况下，这种稳定的年龄结构意味着年轻病例的流入与现有诊所就诊者年龄的增加相平衡。新转诊病例的模式也已转变为以年轻患者为主，这表明社区中有症状的老年患者大多已被纳入诊所就诊人群。
