The purpose of this study was to determine the prevalence of antipsychotic use among nonaggressive patients with newly diagnosed dementia and to examine indications for antipsychotic use.
Patients had to be veterans older than 60 years, newly diagnosed with dementia (ICD-9-CM criteria) from 2001 to 2004 at the Michael A. DeBakey Veterans Affairs Medical Center in Houston, Tex. Patients diagnosed more than 1 year before telephone screening, living in a nursing home or having a caregiver less than 8 hours a week, and/or having aggression, determined by caregiver response on the Ryden Aggression Scale, were excluded. Medical records of eligible participants were then evaluated on the basis of 5 questions: (1) Was the patient taking an antipsychotic? (2) Were neuropsychiatric symptoms documented, with or without antipsychotics? (3) Did the patient have comorbid psychiatric diagnoses? (4) Did the physician attempt to decrease or discontinue the antipsychotic? and (5) Did the physician attempt non-pharmacologic interventions?
A total of 173 patients were eligible for medical record evaluation. Of these, 29 (17%) had been prescribed antipsychotics. Depression, nighttime disturbance, and irritability were the most often documented neuropsychiatric symptoms; however, 31% of patients had no documented symptoms. Mood disorder was documented in 36% of patient records; however, 94 patients (54%) had no comorbid psychiatric disorder. Twelve nonpharmacologic interventions were documented for dementia symptoms. Only 2 attempts to discontinue or decrease antipsychotics for the 29 patients using them were documented.
A sizable minority of newly diagnosed, nonaggressive dementia patients are taking antipsychotics. Physicians need greater education and awareness of the benefits of nonpharmacologic interventions.
本研究旨在确定新诊断的非攻击性痴呆患者中抗精神病药物的使用情况,并探讨使用抗精神病药物的指征。
患者必须为60岁以上的退伍军人,于2001年至2004年在德克萨斯州休斯顿的迈克尔·A·德贝基退伍军人事务医疗中心新诊断为痴呆(根据ICD-9-CM标准)。在电话筛查前1年以上被诊断、居住在疗养院或每周有不到8小时护理人员,和/或根据赖登攻击量表上护理人员的回答判断有攻击性的患者被排除。然后根据5个问题对符合条件的参与者的病历进行评估:(1)患者是否正在服用抗精神病药物?(2)是否记录了神经精神症状,无论是否使用抗精神病药物?(3)患者是否有合并的精神疾病诊断?(4)医生是否尝试减少或停用抗精神病药物?(5)医生是否尝试了非药物干预措施?
共有173名患者符合病历评估条件。其中,29名(17%)患者曾被开具抗精神病药物。抑郁、夜间干扰和易怒是最常记录的神经精神症状;然而,31%的患者没有记录症状。36%的患者病历中有情绪障碍记录;然而,94名患者(54%)没有合并精神疾病。记录了12项针对痴呆症状的非药物干预措施。在使用抗精神病药物的29名患者中,仅有2次尝试减少或停用抗精神病药物的记录。
相当一部分新诊断的、非攻击性痴呆患者正在服用抗精神病药物。医生需要更多关于非药物干预措施益处的教育和认识。
