The recent surge in methamphetamine use highlights the need for timely data on its health effects and healthcare service use impact. However, there is no ICD code for methamphetamine use. This study quantifies the positive predictive value of ICD-9-CM and ICD-10-CM psychostimulant codes for methamphetamine use.
A retrospective chart review of 220 adults aged 18 and older who had an inpatient admission with a psychostimulant-associated billing diagnosis at an urban safety-net hospital. Diagnoses were categorized as either methamphetamine-related or involving another specific psychostimulant. The positive predictive value of both ICD-9-CM or ICD-10-CM psychostimulant diagnosis codes for methamphetamine use was calculated.
ICD-9-CM and ICD-10-CM psychostimulant codes had high positive predictive values of 78.2% (95% CI 70.3%-86.0%) and 85.5% (95% CI 78.8%-92.1%), respectively, for methamphetamine use. The most common non-methamphetamine psychostimulant in our cohort was khat, a cathinone-containing plant native to East Africa, accounting for psychostimulant-related diagnosis in 16 of the 220 hospitalizations.
The high predictive values of psychostimulant codes for methamphetamine use support the application of administrative data in measuring methamphetamine-related healthcare use, as well as co-morbid health conditions and treatment patterns.
冰毒使用的近期激增凸显了及时了解其健康影响和医疗服务使用影响的数据的必要性。然而，目前还没有冰毒使用的 ICD 代码。本研究定量评估了 ICD-9-CM 和 ICD-10-CM 兴奋剂代码对冰毒使用的阳性预测值。
对一家城市保障网医院的 220 名年龄在 18 岁及以上的因与兴奋剂相关的计费诊断而住院的成年人进行回顾性图表审查。诊断分为与冰毒相关或涉及其他特定兴奋剂的诊断。计算了 ICD-9-CM 和 ICD-10-CM 兴奋剂诊断代码对冰毒使用的阳性预测值。
ICD-9-CM 和 ICD-10-CM 兴奋剂代码对冰毒使用的阳性预测值分别为 78.2%（95%CI 70.3%-86.0%）和 85.5%（95%CI 78.8%-92.1%），均较高。在我们的队列中，最常见的非冰毒兴奋剂是阿拉伯茶，一种原产于东非的含有卡西酮的植物，在 220 次住院中有 16 次被诊断为与兴奋剂相关。
兴奋剂代码对冰毒使用的高预测值支持在衡量与冰毒相关的医疗保健使用、合并健康状况和治疗模式方面应用行政数据。
