The objectives of this survey were to examine the effectiveness of a static magnet device--4UlcerCare--in preventing recurrence of leg ulcers after healing. Two hundred and eighty-nine randomly selected purchasers of 4UlcerCare were telephoned and asked to complete a short questionnaire. Our focus was on the 211 respondents who had ulcers that had already healed. The average age of subjects was 70.6 years and sex distribution was 55% female to 45% male. Mean duration of leg ulcers before using 4UlcerCare was 4.4 years. Sixty-five per cent of those surveyed had had ulcer recurrence before using 4UlcerCare, with a mean of 2.41 episodes of ulceration. This was close to the expected recurrence rate in the population of 67%. Using 4UlcerCare daily, these respondents' ulcers had healed within an average of 3.57 months. The survey took place an average of 19.94 months after healing. The manufacturers advise wearing 4UlcerCare daily post-healing, and of those respondents that had, none had suffered any recurrence. Extrapolating these results across the health economy, an estimate has been made of a potential pound153.7 million per year saving on leg ulcer care to the NHS.
本次调查的目的是检验一种静态磁疗设备——4UlcerCare——在预防腿部溃疡愈合后复发方面的效果。我们随机致电了289位4UlcerCare的购买者，要求他们填写一份简短的问卷。我们关注的是211位溃疡已经愈合的受访者。受试者的平均年龄为70.6岁，性别分布为女性55%，男性45%。在使用4UlcerCare之前，腿部溃疡的平均病程为4.4年。65%的受访者在使用4UlcerCare之前有过溃疡复发，平均溃疡发作次数为2.41次。这与该人群67%的预期复发率相近。这些受访者每天使用4UlcerCare，其溃疡平均在3.57个月内愈合。调查在愈合后平均19.94个月进行。制造商建议愈合后每天佩戴4UlcerCare，在那些遵循此建议的受访者中，无人出现复发情况。将这些结果推广至整个医疗经济领域，据估计，每年可为英国国家医疗服务体系（NHS）节省1.537亿英镑的腿部溃疡护理费用。
