The Centers for Medicare & Medicaid Services' National Partnership to Improve Dementia Care in Nursing Homes (hereafter referred to as the partnership) was established to improve the quality of care for patients with dementia, measured by the rate of antipsychotic prescribing.
To determine the association of the partnership with trends in prescribing of antipsychotic and other psychotropic medication among older adults in long-term care.
DESIGN, SETTING, AND PARTICIPANTS: This interrupted time-series analysis of a 20% Medicare sample from January 1, 2009, to December 31, 2014, was conducted among 637 426 fee-for-service Medicare beneficiaries in long-term care with Part D coverage. Data analysis was conducted from May 1, 2017, to January 9, 2018.
Quarterly prevalence of use of antipsychotic and nonantipsychotic psychotropic medications (antidepressants, mood stabilizers [eg, valproic acid and carbamazepine], benzodiazepines, and other anxiolytics or sedative-hypnotics).
Among the 637 426 individuals in the study (446 538 women and 190 888 men; mean [SD] age at entering nursing home, 79.3 [12.1] years), psychotropic use was declining before initiation of the partnership with the exception of mood stabilizers. In the first quarter of 2009, a total of 31 056 of 145 841 patients (21.3%) were prescribed antipsychotics, which declined at a quarterly rate of -0.53% (95% CI, -0.63% to -0.44%; P < .001) until the start of the partnership. At that point, the quarterly rate of decline decreased to -0.29% (95% CI, -0.39% to -0.20%; P < .001), a postpartnership slowing of 0.24% per quarter (95% CI, 0.09%-0.39%; P = .003). The use of mood stabilizers was growing before initiation of the partnership and then accelerated after initiation of the partnership (rate, 0.22%; 95% CI, 0.18%-0.25%; P < .001; rate change, 0.14%; 95% CI, 0.10%-0.18%; P < .001), reaching 71 492 of 355 716 patients (20.1%) by the final quarter of 2014. Antidepressants were the most commonly prescribed medication overall: in the beginning of 2009, a total of 75 841 of 145 841 patients (52.0%) were prescribed antidepressants. As with antipsychotics, antidepressant use declined both before and after initiation of the partnership, but the decrease slowed (rate change, 0.34%; 95% CI, 0.18%-0.50%; P < .001). Findings were similar when limited to patients with dementia.
Prescribing of psychotropic medications to patients in long-term care has declined, although the partnership did not accelerate this decrease. However, the use of mood stabilizers, possibly as a substitute for antipsychotics, increased and accelerated after initiation of the partnership in both long-term care residents overall and in those with dementia. Measuring use of antipsychotics alone may be an inadequate proxy for quality of care and may have contributed to a shift in prescribing to alternative medications with a poorer risk-benefit balance.
重要性:医疗保险和医疗补助服务中心的国家改善疗养院痴呆症护理伙伴关系(以下简称伙伴关系)的成立旨在通过抗精神病药物处方率来提高痴呆症患者的护理质量。
目的:确定伙伴关系与长期护理中老年人抗精神病药物和其他精神药物处方趋势之间的关联。
设计、设置和参与者:本研究采用 2009 年 1 月 1 日至 2014 年 12 月 31 日期间 Medicare 样本的 20%进行了一项中断时间序列分析,涉及 637426 名在长期护理中接受 Part D 覆盖的 Medicare 受益人的自费服务。数据分析于 2017 年 5 月 1 日至 2018 年 1 月 9 日进行。
主要结果和测量:抗精神病药物和非抗精神病精神药物(抗抑郁药、情绪稳定剂[如丙戊酸和卡马西平]、苯二氮䓬类药物和其他抗焦虑药或镇静催眠药)的季度使用率。
结果:在这项研究中的 637426 名个体中(446538 名女性和 190888 名男性;进入疗养院时的平均[标准差]年龄为 79.3[12.1]岁),除了情绪稳定剂之外,精神药物的使用在伙伴关系开始之前一直在下降。在 2009 年第一季度,共有 145841 名患者中的 31056 人(21.3%)被开了抗精神病药物,这一比例以每季度-0.53%的速度下降(95%置信区间,-0.63%至-0.44%;P<.001),直到伙伴关系开始。从那时起,季度下降速度降至-0.29%(95%置信区间,-0.39%至-0.20%;P<.001),每季度下降速度减慢 0.24%(95%置信区间,0.09%-0.39%;P=.003)。情绪稳定剂的使用在伙伴关系开始之前呈上升趋势,然后在伙伴关系开始后加速(速度为 0.22%;95%置信区间,0.18%-0.25%;P<.001;速度变化为 0.14%;95%置信区间,0.10%-0.18%;P<.001),到 2014 年最后一个季度,共有 355716 名患者中的 71492 名(20.1%)使用了情绪稳定剂。抗抑郁药是最常用的药物:在 2009 年初,共有 145841 名患者中的 75841 人(52.0%)开了抗抑郁药。与抗精神病药物一样,抗抑郁药的使用在伙伴关系开始之前和之后都有所下降,但下降速度放缓(速度变化为 0.34%;95%置信区间,0.18%-0.50%;P<.001)。当仅限于痴呆症患者时,结果也相似。
结论和相关性:尽管伙伴关系没有加速这种下降,但长期护理中患者的精神药物处方数量已经下降。然而,在整个长期护理居民中,以及在痴呆症患者中,情绪稳定剂的使用增加且加速,这可能是抗精神病药物的替代品。单独测量抗精神病药物的使用可能不足以作为护理质量的替代指标,并且可能导致了替代药物的处方转变,这些药物的风险-效益平衡较差。
