Patient Factors Associated with Failure to Diagnose Tuberculosis in the Emergency Department

Individual and public health consequences associated with a missed diagnosis of pulmonary tuberculosis in the emergency department: A retrospective cohort study

“…The most responsible ED discharge diagnosis was PTB in 92 (10.9%), pulmonary 'other' in 273 (32%) and non-pulmonary in 480 (56.8%). ED attendees had a median (IQR) health system delay of 27 (7,180) days and, compared to non-ED attendees were more likely to die a TB-related death 5.9% vs 1.2%, p = 0.001.

“…Previous studies have shown that ED use by patients with TB (all forms) was substantial; use, however, likely varies by hospital, location, country, and other factors [2][3][4][5][6][7][8][9]. In the present study, we sought to confirm the extent of use over a large jurisdiction (>100 EDs) in adult patients with PTB.…”

“…In 2016, a Commonwealth Fund survey found Canadians were more likely to seek care in an ED than citizens of ten comparator countries [1]. Emergency department use by patients with tuberculosis (TB) in highincome, low-incidence countries, like Canada, is well-documented [2][3][4][5][6][7][8][9]. Relatively rare conditions like TB are challenging to diagnose when patients present with non-specific complaints and/or in high throughput settings; missed diagnoses generate individual consequences, or, as with a missed diagnosis of pulmonary TB (PTB), the communicable form of TB, both individual and public health consequences.…”

Misdiagnosis of Chikungunya Virus Infection: Comparison of Old and Younger Adults

“…Our finding here that there is a higher rate of misdiagnosis in older adults underscores the need for specific instruments for this age group. Other authors have previously studied the rate of diagnostic errors in the ED in individuals with pulmonary tuberculosis and identified atypical presentation and unresponsiveness as factors associated with greater rate of misdiagnosis. It was previously reported that there is a higher rate of atypical presentations of CVI in individuals aged 65 and older .…”

Screening for tuberculosis among high-risk groups attending London emergency departments: a prospective observational study

“…Previous studies have retrospectively reviewed ED presentations among notified TB cases in lowincidence settings, [4,[9][10][11][12] and examined the yield of TB screening in high-incidence countries. [13,14].…”
