背景：中风后失语的估计发生率为 18% 至 38%。尽管有几项研究计算了中风幸存者的失语率，但还没有具体的研究描述美国 (US) 急症护理医院出院的中风患者中风后失语率。目的：估计美国急症护理医院出院的中风患者失语症的出院率 (HDR)。方法和程序：医疗保健成本和利用项目 (HCUP) 数据 (2011-2012) 来自八个州的便利样本对（俄勒冈州、亚利桑那州、科罗拉多州、佛罗里达州、肯塔基州、北卡罗来纳州、南卡罗来纳州、阿肯色州）进行分析以计算失语症发生率。 结果与结果：2011-2012 年，在这八个代表性州的 152,972 名因中风住院的成年人中，28,086 人（18.4%）因失语症出院。两年期间，八个州的失语症 HDR 范围为 14.3% 至 24.9%。与黑人、西班牙裔和其他人相比，白人失语症的发生率最高。 77% 的样本年龄在 65 岁及以上，56% 是女性，医疗保险是主要保险类型。 36% 的样本患有四种或更多合并症，超过一半 (52%) 出院到熟练护理、中级护理或其他类型的机构。 结论：本研究中观察到的失语症 HDR 处于其他国家先前报告的比率的较低端。在解释这些发现时，应考虑中风发生率的下降、失语症的主要原因以及本研究中用于计算失语症 HDR 的方法。
Background: Estimated rates of post-stroke aphasia range from 18% to 38%. Despite the existence of several studies that have calculated rates of aphasia among stroke survivors, no specific study has emerged that describes the rate of post-stroke aphasia among stroke patients discharged from acute care hospitals in the United States (US).Aim: To estimate the hospital discharge rate (HDR) of aphasia in stroke patients discharged from acute care hospitals in the US.Methods & Procedures: Healthcare Cost and Utilization Project (HCUP) data (2011-2012) derived from a convenience sample of eight states (Oregon, Arizona, Colorado, Florida, Kentucky, North Carolina, South Carolina, Arkansas) were analyzed to calculate rate of aphasia.Outcomes & Results: In 2011-2012, among 152,972 adults who were hospitalized for a stroke in the eight representative states, 28,086 (18.4%) were discharged with aphasia. The HDR of aphasia ranged from 14.3% to 24.9% across the eight states over the two-year period. The rate of aphasia was highest among Whites compared to Blacks, Hispanics and Other. Seventy-seven percent of the sample was age 65 and older, 56% was female and Medicare was the primary insurance type. Thirty-six percent of the sample had four or more comorbid conditions and more than half (52%) were discharged to skilled nursing, intermediate care or another type of facility.Conclusions: The HDR of aphasia observed in this study is on the lower end of rates previously reported in other countries. The declining rate of stroke, the primary underlying cause of aphasia and the methodological approach used to calculate HDR of aphasia in this study, should be taken into consideration in the interpretation of these findings.
