Self-monitoring by heart failure (HF) patients of worsening symptoms caused by fluid overload is a cornerstone of HF care. Disease management has improved outcomes in HF; however, these resource-intensive programs are limited to urban centers and are generally unavailable in rural or limited health care access areas. This pilot study sought to determine whether a simplified education program focused on a single component of disease management (symptom recognition and management of fluid weight) could improve knowledge, patient-reported self-care behavior, and HF severity in a rural setting.
This randomized clinical trial enrolled 36 rural HF patients into an intervention or control group. The intervention group received a simplified education program with a follow-up phone call focusing on symptom management delivered by a non-cardiac-trained nurse. Patient knowledge, self-care behaviors, and HF severity (B-natriuretic peptide [BNP]) were measured at enrollment and at 3 months.
The sample was primarily white men and married with a mean age of 71 years and ejection fraction of 47%. There were no differences between groups in knowledge, self-care behaviors and BNP at baseline; however, knowledge and self-care behavior related to daily weights improved significantly at 3 months in the intervention group (P = .01 and .03, respectively). Although the changes in mean BNP at 3 months were in the hypothesized direction, the difference between the 2 groups was not significant.
A simplified education program designed for use in resource scarce settings improves knowledge and patient-reported self-care behaviors. These findings are important in providing care to patients with HF in limited access settings but should be studied for longer periods in more heterogeneous populations.
心力衰竭(HF)患者自我监测液体过载引起的症状恶化是HF护理的基石。疾病管理改善了HF的治疗结果;然而,这些资源密集型项目仅限于城市中心,在农村或医疗保健服务有限的地区通常无法获得。这项试点研究旨在确定一个侧重于疾病管理单一组成部分(症状识别和液体体重管理)的简化教育项目是否能改善农村地区患者的知识水平、患者报告的自我护理行为和HF严重程度。
这项随机临床试验将36名农村HF患者纳入干预组或对照组。干预组接受了一个简化的教育项目,并由一名未经心脏专业培训的护士通过后续电话进行症状管理指导。在入组时和3个月时测量患者的知识水平、自我护理行为和HF严重程度(B型利钠肽[BNP])。
样本主要是白人男性,已婚,平均年龄71岁,射血分数为47%。两组在基线时的知识水平、自我护理行为和BNP方面没有差异;然而,干预组在3个月时与每日体重相关的知识和自我护理行为有显著改善(P分别为.01和.03)。尽管3个月时平均BNP的变化方向符合假设,但两组之间的差异不显著。
一个为资源匮乏环境设计的简化教育项目可提高知识水平和患者报告的自我护理行为。这些发现对于在医疗服务有限的环境中为HF患者提供护理很重要,但应在更多样化的人群中进行更长时间的研究。
