Purpose: Primary care physicians (PCPs) often do not respond to prompts based upon criteria-based depression screens, perhaps because these prompts do not account for depression severity. We conducted this pilot study to determine the feasibility of prompting for both diagnostic criteria and severity and to assess whether depression would be more attended to with positive "dual prompts" than prompts based on either criteria or symptom severity alone.
Methods: Immediately prior to a routine care appointment, 87 adults from three primary care practices completed the PRIME-MD Clinician Evaluation Guide Mood Module (PRIME-MD; assesses depression criteria) and the Brief Depression Rating (BDR; assesses depressive symptom severity), and their results were issued in a salient PCP prompt on the chart. Immediately afterwards, patients reported the impact of the screening results upon treatment decisions during the encounter. Data were analyzed by X2, analysis of variance, and binomial regression.
Results: Compared to subjects screening positive on either depression criteria or severity alone (n = 10), those patients on both (n = 17) were more likely to report discussing depression, and agreement that the physician and patient decided treatment was needed and initiated or continued. There were no differences in patient satisfaction based on screening results. After accounting for PRIME-MD results, BDR scores predicted agreement with the physician and patient decided treatment was needed (OR = 22.03; 95% CI: 2.05-236.46).
Conclusions: Supplementary severity-based depression screening is feasible, and might overcome the limitations of criteria-based screening alone. Future research could test this hypothesis in a large randomized trial.
