We evaluated a structured pharmaceutical care program for elderly patients (> 65 yrs) with congestive heart failure (CHF) based on objective measures of disease control, quality of life, and use of health care facilities in a randomized, controlled, longitudinal, prospective clinical trial. The 42 patients in group A received education from a pharmacist on the disease and its treatment, and lifestyle changes that could help control symptoms. Patients also were encouraged to monitor their symptoms and comply with prescribed drug therapy. If necessary, dosage regimens were simplified in liaison with hospital physicians. The 41 control patients (group B) received standard care. The following outcome measures were assessed in all patients at baseline (before the start of the trial) and at 3, 6, 9, and 12 months: 2-minute walk test, blood pressure, body weight, pulse, forced vital capacity, quality of life [disease-specific (Minnesota Living with Heart Failure questionnaire) and generic (SF-36)], knowledge of symptoms and drugs, compliance with therapy, and use of health care facilities (hospital admissions, visits to emergency room, emergency calls). Patients in group A showed improved compliance with drug therapy, which in turn improved their exercise capacity compared with those in group B; education on management of symptoms, lifestyle changes, and dietary recommendations were also of benefit. Group A patients significantly improved knowledge of their drug therapy over the 12-month study and had fewer hospital admissions compared with group B patients. They also had improved outcomes compared with group B, despite the small samples. An extension of this trial to other sites with pooling of results would provide additional evidence of the value of this structured program in elderly patients with CHF.
在一项随机、对照、纵向、前瞻性临床试验中,我们基于疾病控制、生活质量和医疗保健设施使用情况的客观指标,对老年(>65岁)充血性心力衰竭(CHF)患者的结构化药物治疗方案进行了评估。A组的42名患者接受了药剂师关于疾病及其治疗的教育,以及有助于控制症状的生活方式改变方面的教育。患者还被鼓励监测自身症状并遵守规定的药物治疗。如有必要,与医院医生联系简化给药方案。41名对照患者(B组)接受标准护理。在基线(试验开始前)以及3、6、9和12个月时,对所有患者评估以下结局指标:2分钟步行试验、血压、体重、脉搏、用力肺活量、生活质量[疾病特异性(明尼苏达心力衰竭生活问卷)和通用型(SF-36)]、症状和药物知识、治疗依从性以及医疗保健设施的使用情况(住院、急诊室就诊、紧急呼叫)。与B组患者相比,A组患者的药物治疗依从性有所提高,这反过来又改善了他们的运动能力;关于症状管理、生活方式改变和饮食建议的教育也有益处。在为期12个月的研究中,A组患者对药物治疗的知识显著提高,与B组患者相比,住院次数更少。尽管样本量较小,但与B组相比,他们的结局也有所改善。将该试验扩展到其他地点并汇总结果,将为这种结构化方案对老年CHF患者的价值提供更多证据。
