The aim of this study is to: (a) develop an evidence-based multidisciplinary educational intervention for patients with a venous leg ulcer; and (b) conduct a pilot study to assess the feasibility of the intervention in the clinical setting.
A two-stage study design was used: (a) an multidisciplinary expert committee designed an educational intervention including support materials; and (b) a pilot randomized controlled trial was conducted to assess the feasibility of the intervention in one wound care outpatient clinic in Western Switzerland.
A multidisciplinary expert committee identified evidence for effective care interventions to improve venous leg ulcer patients' wound healing and recurrences rates. They subsequently designed the educational intervention and support materials. In this pilot study venous leg ulcer patients were then randomly assigned to receive multidisciplinary education or standard care from March-July 2018. The objective was to evaluate the feasibility of the intervention in the clinical setting. Allocation to groups was achieved to concealed, simple randomization. Participants and study nurses were not blinded, data analyst was blinded.
The intervention, including support material was developed. Twelve of 16 invited venous leg ulcer patients were recruited and randomized (control group N = 6; intervention group N = 6). Participation rate was 75%. The implementation of the intervention was feasible in the clinical setting. The performance of the Venous Leg Ulcer Self Efficacy Tool for measuring adherence to therapy and the Mini Nutritional Assessment and Frequent Food Questionnaire for the assessment of the nutritional intake was satisfactory. However, Fitbit smartwatch for measuring activity was not a suitable device in this study population.
The implementation of the designed multidisciplinary educational program was feasible. The pilot study identified weaknesses in the study protocol, which will be amended for the full-size clinical trial.
Findings of the pilot study informed the improvement of the design of the main study.
本研究旨在:(a) 为静脉溃疡患者制定一项基于循证的多学科教育干预措施;(b) 开展一项试点研究,评估该干预措施在临床环境中的可行性。
采用两阶段研究设计:(a) 多学科专家委员会设计了一项教育干预措施,包括支持材料;(b) 进行了一项试点随机对照试验,以评估该干预措施在瑞士西部一家伤口护理门诊中的可行性。
多学科专家委员会确定了改善静脉溃疡患者伤口愈合和复发率的有效护理干预措施的证据。他们随后设计了教育干预措施和支持材料。在这项试点研究中,静脉溃疡患者于 2018 年 3 月至 7 月被随机分配接受多学科教育或标准护理。目的是评估该干预措施在临床环境中的可行性。分组采用隐藏的简单随机化。参与者和研究护士未设盲,数据分析员设盲。
开发了包括支持材料在内的干预措施。16 名受邀静脉溃疡患者中有 12 名(对照组 N=6;干预组 N=6)接受了随机分组。参与率为 75%。该干预措施在临床环境中是可行的。实施该干预措施的过程中,对治疗依从性的测量采用静脉溃疡自我效能工具、营养摄入的评估采用微型营养评估和频繁食物问卷,表现良好。然而,Fitbit 智能手表在该研究人群中并不适合作为测量活动的设备。
设计的多学科教育计划的实施是可行的。试点研究发现研究方案存在弱点,将在全尺寸临床试验中进行修订。
试点研究的结果为主要研究设计的改进提供了信息。
