In the United States, 20% or more of nursing home residents receive antipsychotic drugs, primarily for the behavioral manifestations of dementia. This high level of use of drugs with substantial toxicity has engendered a strong and persistent controversy and recently has led to explicit regulatory measures to curtail use (Omnibus Budget Reconciliation Act of 1987). We developed and tested a comprehensive program to reduce antipsychotic use through education of physicians, nurses, and other nursing home staff. The primary elements of the program were instruction in use of behavioral techniques to manage behavior problems and encouragement of a trial of gradual antipsychotic withdrawal.
In a nonrandomized controlled trial, the program was implemented (beginning in August 1990) in two rural Tennessee community nursing homes with elevated antipsychotic use; two other comparable homes were selected as concurrent controls.
Throughout the study 194 residents were in the education homes and 184 were in the control homes. Residents in both groups of homes had comparable demographic characteristics and functional status, and each group had a baseline rate of 29 days of antipsychotic use per 100 days of nursing home residence.
The primary end points were postintervention changes in administration of antipsychotics and other psychotropic drugs, use of physical restraints, and frequency of behavior problems.
Days of antipsychotic use decreased by 72% in the education homes vs 13% in the control homes (P < .001). No significant changes were noted in the use of other psychotropic drugs in either group. Days of physical restraint use decreased 36% in the education homes vs 5% in the control homes (P < .001). Behavior problem frequency did not increase in either group, even among the 48% of baseline antipsychotic users in the education homes who had antipsychotic drug regimens discontinued for 3 or more months.
The educational program led to a substantial reduction in antipsychotic use with no increase in the frequency of behavior problems. This suggests that for many antipsychotic drug users benefits may be marginal and that programs to reduce such drug use among the 250,000 US nursing home residents receiving these drugs should have high priority.
在美国,20%或更多的养老院居民接受抗精神病药物治疗,主要用于治疗痴呆症的行为表现。这种大量使用具有显著毒性药物的情况引发了强烈且持久的争议,最近还导致了明确的监管措施以减少使用(1987年《综合预算协调法案》)。我们制定并测试了一项综合计划,通过对医生、护士和其他养老院工作人员进行教育来减少抗精神病药物的使用。该计划的主要内容包括指导使用行为技术来管理行为问题,并鼓励尝试逐步停用抗精神病药物。
在一项非随机对照试验中,该计划于1990年8月开始在田纳西州农村地区两家抗精神病药物使用量较高的社区养老院实施;另外两家类似的养老院被选为同期对照。
在整个研究过程中,194名居民在接受教育的养老院,184名居民在对照养老院。两组养老院的居民在人口统计学特征和功能状态方面具有可比性,每组每100天养老院居住时间的抗精神病药物使用基线率均为29天。
主要终点是干预后抗精神病药物和其他精神药物的使用变化、身体约束的使用情况以及行为问题的发生频率。
接受教育的养老院抗精神病药物使用天数减少了72%,而对照养老院减少了13%(P <.001)。两组中其他精神药物的使用均未出现显著变化。接受教育的养老院身体约束使用天数减少了36%,对照养老院减少了5%(P <.001)。两组中行为问题的发生频率均未增加,即使在接受教育的养老院中48%的基线抗精神病药物使用者中,其抗精神病药物治疗方案停用3个月或更长时间的情况下也是如此。
该教育计划导致抗精神病药物使用大幅减少,且行为问题发生频率未增加。这表明对于许多抗精神病药物使用者来说,益处可能微乎其微,并且在美国25万接受这些药物治疗的养老院居民中减少此类药物使用的计划应具有高度优先性。
