  • Title: Voluntary physician switching by human immunodeficiency virus-infected individuals: a national study of patient, physician, and organizational factors.
    Author: Rodriguez HP, Wilson IB, Landon BE, Marsden PV, Cleary PD.
    Journal: Med Care; 2007 Mar; 45(3):189-98. PubMed ID: 17304075.
    Abstract:
    OBJECTIVE: We sought to assess which patient, physician, and organizational factors are related to voluntary physician switching among human immunodeficiency virus (HIV)-infected patients. DESIGN: We analyzed the results from a 3-wave survey of patients conducted by the HIV Cost and Services Utilization Study (HCSUS), a longitudinal study of a nationally representative sample of noninstitutionalized HIV-infected individuals receiving care in the contiguous United States. Physicians providing care and care site directors were surveyed once. Relationships of interpersonal aspects of care, access and continuity, technical quality of care, and physician and site characteristics to voluntary switching were analyzed using multilevel logistic regression models that nested repeated observations within patients, patients within clinicians, and clinicians within region. RESULTS: Approximately 15% of patients voluntarily changed their usual clinicians during the 2-year study period. In a multivariate model, lower voluntary switching was predicted by patient trust (odds ratio [OR]=0.74; 95% confidence interval [95% CI]=0.61-0.90), physician antiretroviral knowledge (OR=0.26; 95% CI 0.13-0.53), moderate (rather than low or high) HIV patient volume at a care site (OR=0.09; 95% CI=0.03-0.31), and Ryan White Care Act funding (OR=0.27, 95% CI=0.14-0.52). CONCLUSIONS: Patients with chronic illnesses may use several markers of specialization and technical quality to make decisions about their care. These results challenge the notion that patients cannot assess the quality of care they receive.
