Which is more important for outcome: the physician's or the patient's understanding of a health problem? A 2-year follow-up study in primary care

Abstract

Objective: We sought to examine (1) whether the patients' and the family physicians' (FPs') beliefs about the nature of a health problem predict health outcomes and (2) whether the FPs were aware of their patients' beliefs.

Methods: A 2-year follow-up study of 38 FPs and 1131 patients presenting with well-defined physical disease (n=922) or medically unexplained symptoms (MUS) (n=209) according to the FPs was conducted. Before the consultation, patients categorized their health problem as being either physical or both physical and psychological. After the consultation, the FPs judged their patients' understanding of the health problem. Outcome measures were (1) patient satisfaction (seven-item Patient Satisfaction Consultation Questionnaire), (2) self-perceived mental and physical health (component summaries of the Medical Outcome Study's Short Form: SF-36) and (3) health care use extracted from patient registers.

Main results: Patients with MUS according to the FPs and patients who believed that the nature of their health problem was both physical and psychological had higher health care use and worse self-rated health than patients in cases where both the FP and the patient had a physical understanding. Patients presenting MUS were more dissatisfied with the consultation than patients with well-defined physical disease. Overall, the FPs' perceptions of their patients' understanding were accurate in 82% of the consultations, but when the patients had a both physical and psychological understanding of their health problem, the FPs were right in only 26% of the consultations.

Conclusions: Both FPs' diagnoses and patients' beliefs predict important health outcomes such as patient satisfaction, use of health care and self-rated health.
