The authors have conducted a series of pressure sore prevalence surveys within one health district over a 4-year period. Additional surveys of the availability and deployment of pressure redistributing (PR) bed mattresses have also been made within the same district. The prevalence of pressure sores increased from 6.8% (1986) to 14.2% (1989) while the available stocks of PR mattresses increased from 69 (1987) to 186 (1989). Our results appear to question the common assumption that successful pressure sore prevention can be achieved through expanding the stocks of PR mattresses. Five possible reasons why the increase in mattress provision was matched with an increased prevalence of pressure sores are forwarded. The use of measures of prevalence rather than incidence rates to monitor the effects of clinical initiatives is discussed.
作者在一个健康区进行了为期4年的一系列压疮患病率调查。同时还在同一地区对减压床垫的供应和使用情况进行了额外调查。压疮患病率从1986年的6.8%上升到1989年的14.2%，而减压床垫的可用库存从1987年的69个增加到1989年的186个。我们的结果似乎对通过增加减压床垫库存就能成功预防压疮这一普遍假设提出了质疑。文中提出了床垫供应增加却伴随着压疮患病率上升的五个可能原因。还讨论了使用患病率指标而非发病率指标来监测临床举措效果的问题。
