To assess pre-hospital patient delay and its associated variables in patients with diabetic foot problems.
We classified 270 patients with diabetic foot problems retrospectively based on the distribution of pre-hospital delay. Clinical, demographic and socio-economic data were collected. Logistic regression analysis was performed to examine independent associations with patient delay.
The median pre-hospital delay time was 46.49 days. Patients reported short (≤ 1 week; 77 patients, 28.5%), moderate (> 1 week and ≤ 1 month; 106 patients, 39.3%) and long delays (> 1 month; 87 patients, 32.2%). In a univariate analysis, nine variables were associated with a longer delay (P < 0.05): (1) no previous ulcer; (2) no health insurance; (3) poor housing conditions; (4) low income level; (5) low educational level; (6) infrequent foot inspection; (7) few follow-up medical visits; (8) absence of diabetic foot education; (9) lack of knowledge of foot lesion warning signals. A multivariate analysis showed that absence of diabetic foot education (odds ratio 2.70, 95% CI 1.03-7.06, P = 0.043) and lack of knowledge of foot lesion warning signals (odds ratio 2.14, 95% CI 1.16-3.94, P = 0.015) were independent predictors of long patient delay. Long delay increased the risk of amputation (odds ratio 2.22, 95% CI 1.36-3.64, P = 0.002) and mortality (odds ratio 2.69, 95% CI 1.35-5.33, P = 0.005).
A number of factors were involved in pre-hospital delay among patients with diabetic foot problems and contributed to poor outcomes. We recommend developing a community intervention programme that targets at-risk communities to encourage earlier multidisciplinary team assessment to reduce disparities and improve foot outcomes in patients with diabetes.
评估糖尿病足患者的院前患者延迟及其相关变量。
我们根据院前延迟分布将 270 例糖尿病足患者回顾性分类。收集临床、人口统计学和社会经济数据。进行逻辑回归分析以检查与患者延迟相关的独立关联。
中位院前延迟时间为 46.49 天。患者报告了短(≤1 周;77 例,28.5%)、中(>1 周和≤1 个月;106 例,39.3%)和长延迟(>1 个月;87 例,32.2%)。在单因素分析中,有九个变量与较长的延迟相关(P<0.05):(1)无既往溃疡;(2)无健康保险;(3)住房条件差;(4)收入水平低;(5)教育水平低;(6)足部检查不频繁;(7)随访医疗就诊次数少;(8)缺乏糖尿病足教育;(9)缺乏足部病变预警信号知识。多因素分析显示,缺乏糖尿病足教育(比值比 2.70,95%可信区间 1.03-7.06,P=0.043)和缺乏足部病变预警信号知识(比值比 2.14,95%可信区间 1.16-3.94,P=0.015)是患者延迟的独立预测因素。长时间的延迟增加了截肢(比值比 2.22,95%可信区间 1.36-3.64,P=0.002)和死亡(比值比 2.69,95%可信区间 1.35-5.33,P=0.005)的风险。
糖尿病足患者的院前延迟涉及多个因素,并导致不良结局。我们建议制定社区干预计划,针对高危社区,鼓励尽早进行多学科团队评估,以减少差异并改善糖尿病患者的足部结局。
