Treatment Episode Data Set -- Admissions (TEDS-A), 2009

The Treatment Episode Data Set -- Admissions (TEDS-A) is a national census data system of annual admissions to substance abuse treatment facilities. TEDS-A provides annual data on the number and characteristics of persons admitted to public and private substance abuse treatment programs that receive public funding. The unit of analysis is a treatment admission. TEDS consists of data reported to state substance abuse agencies by the treatment programs, which in turn report it to SAMHSA.
A sister data system, called the Treatment Episode Data Set -- Discharges (TEDS-D), collects data on discharges from substance abuse treatment facilities. The first year of TEDS-A data is 1992, while the first year of TEDS-D is 2006.
TEDS variables that are required to be reported are called the "Minimum Data Set (MDS)", while those that are optional are called the "Supplemental Data Set (SuDS)".
Variables in the MDS include: information on service setting, number of prior treatments, primary source of referral, gender, race, ethnicity, education, employment status, substance(s) abused, route of administration, frequency of use, age at first use, and whether methadone was prescribed in treatment. Supplemental variables include: diagnosis codes, presence of psychiatric problems, living arrangements, source of income, health insurance, expected source of payment, pregnancy and veteran status, marital status, detailed not in labor force codes, detailed criminal justice referral codes, days waiting to enter treatment, and the number of arrests in the 30 days prior to admissions (starting in 2008) .
Substances abused include alcohol, cocaine and crack, marijuana and hashish, heroin, nonprescription methadone, other opiates and synthetics, PCP, other hallucinogens, methamphetamine, other amphetamines, other stimulants, benzodiazepines, other non-benzodiazepine tranquilizers, barbiturates, other non-barbiturate sedatives or hypnotics, inhalants, over-the-counter medications, and other substances.
Created variables include total number of substances reported, intravenous drug use (IDU), and flags for any mention of specific substances.

治疗事件数据集——入院版（Treatment Episode Data Set -- Admissions, TEDS-A）是一套针对物质滥用治疗机构年度入院情况的全国普查数据系统。TEDS-A 会提供接受公共资助的公立与私立物质滥用治疗项目的入院人数及人群特征的年度数据，其分析单位为治疗入院记录。TEDS 的数据由各治疗项目上报至各州物质滥用管理机构，再由这些机构汇总上报至物质滥用与精神健康服务管理局（Substance Abuse and Mental Health Services Administration, SAMHSA）。
其姊妹数据系统为治疗事件数据集——出院版（Treatment Episode Data Set -- Discharges, TEDS-D），负责收集物质滥用治疗机构的出院数据。TEDS-A 的首个数据年份为1992年，而TEDS-D 的首个数据年份则为2006年。
TEDS 中要求强制上报的变量被称为"最小数据集（Minimum Data Set, MDS）"，可选上报的变量则被称为"补充数据集（Supplemental Data Set, SuDS）"。
最小数据集包含的变量有：服务环境信息、既往治疗次数、主要转诊来源、性别、种族、族裔、受教育程度、就业状况、滥用物质种类、给药途径、使用频率、首次使用年龄，以及治疗中是否开具美沙酮处方。补充变量则包括：诊断编码、精神疾病共病情况、居住安排、收入来源、健康保险、预计支付来源、妊娠与退伍军人身份、婚姻状况、详细的非劳动力编码、详细的刑事司法转诊编码、等待入院的天数，以及入院前30天内的逮捕次数（2008年起新增该项）。
滥用物质涵盖酒精、可卡因与快克可卡因、大麻与哈希什、海洛因、非处方美沙酮、其他阿片类与合成阿片类物质、苯环己哌啶（PCP）、其他致幻剂、甲基苯丙胺、其他苯丙胺类物质、其他兴奋剂、苯二氮䓬类药物、其他非苯二氮䓬类镇静催眠药、巴比妥类药物、其他非巴比妥类镇静剂或催眠药、吸入剂、非处方药物，以及其他物质。
衍生变量包括上报的物质总数量、静脉注射药物使用（intravenous drug use, IDU），以及提及特定物质的标识字段。
