BACKGROUND: @entity341 ( @entity341 ) medication lists (ML) are considered inaccurate based on previous comparisons of @entity341 ML with @entity1 ' self-reporting of medications and reviews of @entity1 ' pharmacy and medical records. OBJECTIVE: To determine the accuracy of @entity341 ML using mass spectrometry analysis of urine samples. METHODS: This was a prospective observational study conducted at an urban tertiary care university hospital. Convenience sampling of @entity1 who underwent @entity341 triage was done. Included were @entity1 18  years or older who were capable of providing informed consent and who reported use of at least one medication. Excluded were @entity1 unable to consent, prisoners, non-English-speaking @entity1 , and @entity1 unwilling or unable to provide a urine sample. Mass spectrometry analysis was performed on enrolled @entity1 ' urine, and their @entity341 triage ML were recorded. Urinalysis results were compared to @entity341 triage ML. Concordance between respective @entity341 triage ML and urinalysis results was determined. Medications were grouped by medication class. The top five discrepant medication classes were identified. RESULTS: There were 100 @entity1 enrolled; 21 @entity1 , although eligible, did not provide a urine sample and were excluded, and one @entity1 withdrew. Mean age was 51  years, and 54 @entity1 were male. Twenty-two medication classes were identified. No @entity1 had 100% concordance of @entity341 triage ML and urinalysis results. Opioid analgesic, sedative hypnotics, cardiac, @entity146 , and nonopioid analgesic medications were the top discrepant medication classes. CONCLUSIONS: @entity341 triage ML obtained by @entity1 recall are inaccurate when compared to medications detected in urine using mass spectrometry analysis.
