Hospice and palliative care programs to relieve suffering and optimize management of terminally ill patients have grown rapidly in the United States. However, there are no data on the need for these services among patients with end-stage heart failure receiving intermittent infusion of intravenous inotropes.
The need for hospice and palliative care programs among patients in end-stage heart failure who receive intermittent infusion of inotropes is investigated.
The study included all stable patients with refractory heart failure symptoms treated with inotropes in our outpatient unit. A total of 73 patients (65 +/- 12 years; left ventricular ejection fraction 22 +/- 9%; New York Heart Association class 3.6 +/- 0.4) were seen during a 49-month period. Of these, 35 patients (48%) met hospice or palliative care evaluation criteria upon referral but were offered, and accepted, the alternative of parenteral inotropes. In all, 1,737 individual outpatient treatment sessions were given, with a mean of 24 +/- 19 sessions per patient (range 5 to 118 sessions), representing a minimum of 9,948 h of inotrope therapy.
A total of 18 (25%) patients died, 6 (8%) patients were withdrawn from the program (3 by their primary physicians and 3 because of significant travel limitations); 4 (5%) patients required continuous intravenous home therapy; and 44 (61%) patients were discharged with significant improvement in their heart failure symptoms. Only 7 of the 18 patients who died had received hospice or palliative care intervention, mainly for the sake of comfort and to ease the transition among family members. The rest of the patients were comfortable and had accepted the natural evolution of their disease; they were not interested in or did not require hospice or palliative care intervention. Of the patients discharged from the outpatient cardiac infusion unit, the interval free of heart failure symptoms after the final infusion treatment ranged from 201 to 489 days, with no need for hospitalization or emergency room visits.
Our results demonstrate that intermittent infusion of intravenous inotropes can be safely administered and can improve symptoms in a significant number of patients, probably by slowing the natural progression of heart failure. Although the full clinical impact of inotrope therapy in an outpatient setting has not been fully defined, other nonhemodynamic-related benefits should be sought and investigated. Our results suggest that intermittent infusion of intravenous inotropes is one of the prominent variables that requires particular attention. In our experience, the institution of intermittent infusions of intravenous inotropes can, in fact, modify end-stage heart failure symptoms that, in most patients, are currently perceived to lead to a terminal event. Thus, appropriate use of intermittent infusion of intravenous inotropes may not only improve functional class and symptoms in a significant number of patients identified as terminal by their poor response to conventional therapy, but it may also facilitate better utilization of hospice and palliative care resources among patients with end-stage heart failure. Furthermore, the need for hospice and palliative care in patients with heart failure should be revisited in view of adjuvant treatment options such as intermittent infusion of intravenous inotropes.
在美国,旨在减轻临终患者痛苦并优化其管理的临终关怀和姑息治疗项目发展迅速。然而,对于接受间歇性静脉注射强心剂治疗的终末期心力衰竭患者,尚无关于这些服务需求的数据。
对接受间歇性强心剂注射的终末期心力衰竭患者的临终关怀和姑息治疗项目需求进行调查。
本研究纳入了在我们门诊接受强心剂治疗的所有难治性心力衰竭症状稳定的患者。在49个月期间共观察了73例患者(年龄65±12岁;左心室射血分数22±9%;纽约心脏病协会心功能分级3.6±0.4)。其中,35例患者(48%)在转诊时符合临终关怀或姑息治疗评估标准,但被提供并接受了静脉注射强心剂的替代方案。总共进行了1737次个体门诊治疗,每位患者平均接受24±19次治疗(范围为5至118次),相当于至少9948小时的强心剂治疗。
共有18例(25%)患者死亡,6例(8%)患者退出该项目(3例由其初级医生决定,3例因出行严重受限);4例(5%)患者需要持续静脉家庭治疗;44例(61%)患者出院时心力衰竭症状有显著改善。18例死亡患者中只有7例接受了临终关怀或姑息治疗干预,主要是为了缓解痛苦并促进家庭成员间的过渡。其余患者情况良好,接受了疾病的自然发展过程;他们对临终关怀或姑息治疗干预不感兴趣或不需要。从门诊心脏输液单元出院的患者中,最后一次输液治疗后无心力衰竭症状的间隔时间为201至489天,无需住院或急诊就诊。
我们的结果表明,间歇性静脉注射强心剂可以安全给药,并且可以使大量患者的症状得到改善,可能是通过减缓心力衰竭的自然进展。尽管强心剂治疗在门诊环境中的全面临床影响尚未完全明确,但应寻求并研究其他与非血流动力学相关的益处。我们的结果表明,间歇性静脉注射强心剂是一个需要特别关注的突出变量。根据我们的经验,间歇性静脉注射强心剂的应用实际上可以改善终末期心力衰竭症状,而目前大多数患者认为这些症状会导致终末事件。因此,适当使用间歇性静脉注射强心剂不仅可以改善大量被传统治疗反应不佳判定为终末期患者的功能分级和症状,还可能促进终末期心力衰竭患者更好地利用临终关怀和姑息治疗资源。此外,鉴于间歇性静脉注射强心剂等辅助治疗选择,应重新审视心力衰竭患者对临终关怀和姑息治疗的需求。
