In 2018, an estimated 19.1 percent of adults in the U.S. civilian noninstitutionalized population experienced any mental illness in the past year, while an estimated 4.6 percent suffered from serious mental illness in the past year. In addition, an estimated 14.4 percent of youths aged 12–17 and 7.2 percent of adults experienced at least one major depressive episode in the past year in 2018. Prescription antidepressants and antipsychotics are two types of drug therapies sometimes prescribed to treat mental illness. As more people use prescription antidepressants and antipsychotics, it is important for policymakers and researchers to understand changes in the utilization of these drugs as well as changes in expenditures for these drugs. This Statistical Brief presents a comparison of prescription antidepressant and antipsychotic utilization and expenditures in the U.S. civilian noninstitutionalized population between the years 2013 and 2018. Estimates are based on the 2013 Medical Expenditure Panel Survey Household Component (MEPS-HC) and the 2018 MEPS-HC. This Brief compares the number of people obtaining at least one prescription for an antidepressant or antipsychotic medication, total prescription fills, and total expenditures for those medications, as well as the average total, out-of-pocket, and third-party payer expenditures per fill. Estimates are presented separately for antidepressants and antipsychotics. Only prescriptions obtained in an outpatient setting (retail and mail-order prescribed medicines) are included in these estimates. Prescription medicines administered in an inpatient setting or in a clinic or physician’s office are excluded. Expenditure estimates are presented in real dollars; estimates for 2013 are inflated to 2018 dollars based on the Gross Domestic Product (GDP) price index (http://www.meps.ahrq.gov/mepsweb/about_meps/Price_Index.shtml). All differences between estimates discussed in the text are statistically significant at the 0.05 level unless otherwise noted.
2018年，估计美国非机构化平民人口中有19.1%的成年人在过去一年中经历过任何精神疾病，而估计有4.6%的人在过去一年中患有严重精神疾病。此外，2018年估计有14.4%的12至17岁青少年和7.2%的成年人在过去一年中至少经历过一次重度抑郁发作。处方抗抑郁药和抗精神病药是有时用于治疗精神疾病的两种药物疗法。随着越来越多的人使用处方抗抑郁药和抗精神病药，政策制定者和研究人员了解这些药物的使用变化以及这些药物的支出变化非常重要。本统计简报比较了2013年至2018年期间美国非机构化平民人口中处方抗抑郁药和抗精神病药的使用情况及支出。估计数基于2013年医疗支出面板调查家庭成分（MEPS-HC）和2018年MEPS-HC。本简报比较了至少获得一张抗抑郁药或抗精神病药处方的人数、这些药物的总处方配药量和总支出，以及每次配药的平均总支出、自付支出和第三方支付者支出。抗抑郁药和抗精神病药的估计数分别列出。这些估计数仅包括在门诊环境（零售和邮购处方药）中获得的处方。住院环境或诊所或医生办公室开具的处方药不包括在内。支出估计数以实际美元表示；2013年的估计数根据国内生产总值（GDP）价格指数（http://www.meps.ahrq.gov/mepsweb/about_meps/Price_Index.shtml）调整为2018年美元。除非另有说明，文本中讨论的估计数之间的所有差异在0.05水平上具有统计学意义。
