Implementing standardized depression screening for adults in a rural setting: a quality initiative

Abstract

Background: Major depressive disorder (MDD) imposes a significant burden, affecting 15-17% of the population. Early detection and intervention are crucial to mitigate adverse health outcomes associated with untreated depression. Clinical guidelines recommend regularly screening patients for depression within the primary care setting. The Patient Health Questionnaire (PHQ) is a widely recognized and validated tool used for depression screening. Local Problem: A rural clinic in Eastern Montana elected to implement a standardized process for administering PHQ-2 and PHQ-9 assessments to their adult primary care population. Methods: The Iowa Model guided the implementation process over eight weeks. Intervention: Nursing staff administered a PHQ-2 to eligible adult patients during primary care appointments. A PHQ-2 score of > or = 3 triggered the nursing staff to administer the PHQ-9. Positive PHQ-9 scores (> or = 5) prompted provider notification and subsequent evaluation for depression. Patients diagnosed with depression or other mental health concerns received appropriate interventions and treatments based on clinical expertise. Data was collected and deidentified before entry into a spreadsheet for further analysis. Results: Nursing staff administered a PHQ-2 to 71.8% (n=326) of eligible patients over the eight weeks. Of those screened, 46 had a positive PHQ-2 result, and 30 had a positive PHQ-9 result. Providers evaluated 100% of patients with a positive PHQ-9, and all were determined to have varying severities of depression. Conclusion: The findings supported the efficacy of the PHQ in identifying depression within a primary care setting. Moreover, these measures promise to enhance mental health care delivery and outcomes in the rural primary care setting.
