The Problem-Analysis-Solution (PAS) system helps pharmacists code patient questions. While it aids in structuring consultations, its reliability for research is limited due to inconsistent coding across pharmacists.

Area of Science:

  • Pharmacy Practice
  • Communication Studies
  • Health Informatics

Background:

  • Effective patient-pharmacist communication is crucial for medication adherence and outcomes.
  • Quantifying and analyzing patient-reported drug information needs can improve pharmacy services.
  • Existing methods for categorizing patient queries may lack structure and consistency.

Purpose of the Study:

  • To develop and evaluate the Problem-Analysis-Solution (PAS) system for quantifying oral communication in pharmacy practice.
  • To assess the reliability and utility of the PAS system for pharmacists in understanding patient drug-related questions.
  • To determine if the PAS system can aid pharmacists in structuring patient consultations.

Main Methods:

  • Development of the PAS system, involving coding patient questions into Problem (P), Analysis (A), and Solution (S) codes.

  • Validation of the PAS system through external and internal assessments involving 41 pharmacists.
  • Calculation of Kappa values to measure inter-rater and intra-rater agreement for the P, A, and S codes.

    • Main Results:

    • External validation showed moderate to poor agreement for P, A, and S codes, indicating varied categorization by pharmacists.
    • Internal validation revealed good reproducibility for P-codes (0.42-0.91) but poor reproducibility for A-codes (0.07-0.35) and S-codes (0-0.68).
    • The PAS system demonstrates potential for pharmacists to register patient questions (P-codes) and structure consultations.

    Conclusions:

    • The PAS system's reliability for research purposes is limited due to inconsistent coding, particularly for A and S codes.
    • Pharmacists can effectively use the P-code component of the PAS system for registering patient queries within their practice.
    • The PAS system shows promise in helping pharmacists structure their communication during patient consultations.
