Missed diagnosis of stroke in the emergency department: a cross-sectional analysis of a large population-based sample.

ABSTRACT: BACKGROUND:Some cerebrovascular events are not diagnosed promptly, potentially resulting in death or disability from missed treatments. We sought to estimate the frequency of missed stroke and examine associations with patient, emergency department (ED), and hospital characteristics. METHODS:Cross-sectional analysis using linked inpatient discharge and ED visit records from the 2009 Healthcare Cost and Utilization Project State Inpatient Databases and 2008-2009 State ED Databases across nine US states. We identified adult patients admitted for stroke with a treat-and-release ED visit in the prior 30 days, considering those given a non-cerebrovascular diagnosis as probable (benign headache or dizziness diagnosis) or potential (any other diagnosis) missed strokes. RESULTS:There were 23,809 potential and 2243 probable missed strokes representing 12.7% and 1.2% of stroke admissions, respectively. Missed hemorrhages (n = 406) were linked to headache while missed ischemic strokes (n = 1435) and transient ischemic attacks (n = 402) were linked to headache or dizziness. Odds of a probable misdiagnosis were lower among men (OR 0.75), older individuals (18-44 years [base]; 45-64:OR 0.43; 65-74:OR 0.28; ? 75:OR 0.19), and Medicare (OR 0.66) or Medicaid (OR 0.70) recipients compared to privately insured patients. Odds were higher among Blacks (OR 1.18), Asian/Pacific Islanders (OR 1.29), and Hispanics (OR 1.30). Odds were higher in non-teaching hospitals (OR 1.45) and low-volume hospitals (OR 1.57). CONCLUSIONS:We estimate 15,000-165,000 misdiagnosed cerebrovascular events annually in US EDs, disproportionately presenting with headache or dizziness. Physicians evaluating these symptoms should be particularly attuned to the possibility of stroke in younger, female, and non-White patients.

Project description:ObjectiveMissed diagnoses of acute ischemic stroke (AIS) in the ED may result in lost opportunities to treat AIS. Our objectives were to describe the rate and clinical characteristics of missed AIS in the ED, to determine clinical predictors of missed AIS, and to report tissue plasminogen (tPA) eligibility among those with missed strokes.MethodsAmong a population of 1.3 million in a five-county region of southwest Ohio and northern Kentucky, cases of AIS that presented to 16 EDs during 2010 were identified using ICD-9 codes followed by physician verification of cases. Missed ED diagnoses were physician-verified strokes that did not receive a diagnosis indicative of stroke in the ED. Bivariate analyses were used to compare clinical characteristics between patients with and without an ED diagnosis of AIS. Logistic regression was used to evaluate predictors of missed AIS diagnoses. Alternative diagnoses given to those with missed AIS were codified. Eligibility for tPA was reported between those with and without a missed stroke diagnosis.ResultsOf 2,027 AIS cases, 14.0% (n = 283) were missed in the ED. Race, sex, and stroke subtypes were similar between those with missed AIS diagnoses and those identified in the ED. Hospital length of stay was longer in those with a missed diagnosis (5 days vs. 3 days, p < 0.0001). Younger age (adjusted odds ratio [aOR] = 0.94, 95% confidence interval [CI] = 0.89 to 0.98) and decreased level of consciousness (LOC) (aOR = 3.58, 95% CI = 2.63 to 4.87) were associated with higher odds of missed AIS. Altered mental status was the most common diagnosis among those with missed AIS. Only 1.1% of those with a missed stroke diagnosis were eligible for tPA.ConclusionIn a large population-based sample of AIS cases, one in seven cases were not diagnosed as AIS in the ED, but the impact on acute treatment rates is likely small. Missed diagnosis was more common among those with decreased LOC, suggesting the need for improved diagnostic approaches in these patients.

Project description:IntroductionUnintended pregnancy disproportionately affects marginalized populations and has significant negative health and financial impacts on women, their families, and society. The emergency department (ED) is a promising alternative setting to increase access to sexual and reproductive health (SRH) services including contraception, especially among marginalized populations. The primary objective of this study was to determine the extent to which adult women of childbearing age who present to the ED would be receptive to receiving contraception and/or information about contraception in the ED. As a secondary objective, we sought to identify the barriers faced in attempting to obtain SRH care in the past.MethodsWe conducted a quantitative, cross-sectional, assisted, in-person survey of women aged 18-50 in the ED setting at two large, urban, academic EDs between June 2018-September 2019. The survey was approved by the institutional review board. Survey items included demographics, interest in contraception initiation and/or receiving information about contraception in the ED, desire to conceive, prior SRH care utilization, and barriers to SRH.ResultsA total of 505 patients participated in the survey. Participants were predominantly single and Black, with a mean age of 31 years, and reporting not wanting to become pregnant in the next year. Of those participants, 55.2% (n = 279) stated they would be interested in receiving information about birth control AND receiving birth control in the ED if it were available. Of those who reported the ability to get pregnant, and not desiring pregnancy in the next year (n = 279, 55.2%), 32.6% were not currently using anything to prevent pregnancy (n = 91). Only 10.5% of participants stated they had experienced barriers to SRH care in the past (n = 53). Participants who experienced barriers to SRH reported higher interest in receiving information and birth control in the ED (74%, n = 39) compared to those who had not experienced barriers (53%, n = 240); (P = 0.004, 95% confidence interval, 1.30-4.66).ConclusionThe majority of women of childbearing age indicated the desire to access contraception services in the ED setting. This finding suggests favorable patient acceptability for an implementation study of contraception services in emergency care.
