An interdisciplinary comparison of consultation outcomes. Psychiatry vs cardiology
Insights
Cardiologists achieved higher concordance with recommendations than psychiatrists. This study compared outcomes for drug and diagnostic actions, finding differences related to consultation timing and specialty.
Area of Science:
- Medical Consultation
- Healthcare Outcomes
- Comparative Effectiveness
Background:
- Comparing physician recommendations is crucial for optimizing patient care.
- Understanding concordance rates between different medical specialties can reveal systemic issues.
Purpose of the Study:
- To compare the concordance rates of recommendations made by cardiologists and psychiatrists.
- To identify factors influencing the outcomes of drug and diagnostic recommendations from these two specialties.
Main Methods:
- Retrospective study analyzing 788 consultations.
- Comparison of concordance rates for drug and diagnostic recommendations.
- Identification of variables associated with recommendation outcomes.
Main Results:
- Cardiologists demonstrated higher concordance rates than psychiatrists for both drug and diagnostic recommendations.
- Discrepancies in drug recommendation concordance were linked to consultation timing and initiation of medication.
- Differences in diagnostic recommendation concordance were primarily associated with the consulting service.
Conclusions:
- Psychiatrists' diagnostic recommendations had less favorable outcomes, potentially due to reasons for consultation, patient expectations, and psychiatrist skill.
- Specialty differences significantly impact recommendation concordance, highlighting areas for targeted improvement in medical consultations.
Abstract:
Responses to cardiologists' and psychiatrists' recommendations for drugs and diagnostic actions were compared in a retrospective study of 788 consultations. Variables significantly related to outcome achieved by cardiologists and psychiatrists were identified; similarities among these variables were evident only for the drug recommendations. Cardiologists' recommendations achieved a higher rate of concordance than psychiatrists' for both drugs and diagnostic actions. For drug recommendations, the interservice discrepancy in concordance was directly related to differences in timing of the consultations and incidence of recommendations to start a drug. For diagnostic recommendations, however, the difference was directly related to the consultants' service. The following factors may explain the less favorable outcome for psychiatrists' diagnostic recommendations: (1) the reasons for seeking psychiatric consultation, (2) the consultees' expectations, and (3) the skill of the psychiatrists in offering these recommendations.
