Emergency department medication history taking: current inefficiency and potential for a self-administered form.

Background: Emergency Departments (EDs) struggle with obtaining accurate medication information from patients.

Objective: Our aim was to estimate the proportion of urban ED patients who are able to complete a self-administered medication form and record patient observations of the medication information process.

Methods: In this cross-sectional study, we consecutively sampled ED patients during various shifts between 8 AM and 10 PM. We created a one-page medication questionnaire that included a list of 49 common medications, categorized by general indications. We asked patients to circle any medications they took and write the names of those not on the form in a dedicated area on the bottom of the page. After their visit, we asked patients to recall which providers had asked them about their medications.

Results: Research staff approached 354 patients; median age was 45 years (interquartile range 29-53 years). Two hundred and forty-nine (70%) completed a form, 61 (17%) were too ill, 19 (5%) could not read it, and 25 (7%) refused to participate. Excluding refusals, 249 of 329 (76%; 95% confidence interval 70-80%) were able to complete the form. Of 209 patients recalling their visit, 180 (86%) indicated that multiple providers took a history, including 103 in which every provider did so, and 9 (4%) indicated that no provider took a medication history.

Conclusions: The process of ED medication information transfer often involves redundant efforts by the health care team. More than 70% of patients presenting for Emergency care were able to complete a self-administered medication information form.
