A two-stage strategy using the Patient Health Questionnaire (PHQ-9) effectively screens for depression in primary care. This approach identifies severe cases while ensuring less severe ones receive necessary treatment.

Area of Science:

  • Primary Care Medicine
  • Psychiatry
  • Clinical Diagnostics

Background:

  • Depression screening in primary care is crucial for early intervention.
  • Accurate and efficient screening tools are needed to manage patient caseloads.
  • A balance is required to identify severe cases without overlooking milder forms.

Purpose of the Study:

  • To evaluate a two-stage depression screening strategy.
  • To determine the utility of the Patient Health Questionnaire (PHQ-9) in primary care settings.
  • To assess the cost-effectiveness of one-time depression screening.

Main Methods:

  • Implementation of a two-stage strategy combining severity assessment and depression criteria.
  • Utilizing the PRIME-MD Patient Health Questionnaire (PHQ-9) for screening.

    • Main Results:

    • The two-stage strategy allows physicians to focus on severe cases while identifying less severe ones.
    • The PHQ-9 demonstrates brevity and high positive predictive value for depression.
    • One-time screening is identified as a cost-effective measure.

    Conclusions:

    • A two-stage screening approach enhances depression case identification in primary care.
    • The PHQ-9 is a highly suitable depression screening tool for primary care physicians.
    • Periodic screening may be considered based on individual patient risk factors.
