Key result
Psychiatric comorbidity identified via outpatient codes was associated with higher 30-day mortality after AMI (OR 1.19; 95% CI 1.09-1.30), whereas inpatient secondary codes showed no association.

Outpatient codes may better identify psychiatric comorbidity tied to post-AMI mortality; leaves open optimal ascertainment for risk models and interventions.

Does the method of identifying psychiatric comorbidity (outpatient vs inpatient codes) affect its association with mortality and revascularization outcomes in patients with acute myocardial infarction?
Odds Ratio: 1.19 (95% CI 1.09–1.3)
Relying on inpatient secondary diagnosis codes underestimates the prevalence of psychiatric comorbidity and its association with adverse outcomes after AMI compared to using prior outpatient codes.
Abrams et al. (2009) conducted a cohort in Acute myocardial infarction (AMI) (n=21,745). Psychiatric comorbidity (identified via outpatient codes) vs. No psychiatric comorbidity was evaluated on 30-day mortality (OR 1.19, 95% CI 1.09 to 1.30). Psychiatric comorbidity identified via outpatient codes was associated with higher 30-day mortality after AMI (OR 1.19; 95% CI 1.09-1.30), whereas inpatient secondary codes showed no association.
