Background: For patients with chronic illnesses, it is hypothesized that effective patient-provider collaboration contributes to improved patient self-care by promoting greater agreement on patient-specific treatment goals and strategies. However, this hypothesis has not been tested in actual encounters of patients with their own physicians.Objective: To assess the extent to which patients with type 2 diabetes agree with their primary care providers (PCPs) on diabetes treatment goals and strategies, the factors that predict agreement, and whether greater agreement is associated with better patient self-management of diabetes.Design: One hundred twenty-seven pairs of patients and their PCPs in two health systems were surveyed about their top 3 diabetes treatment goals (desired outcomes) and strategies to meet those goals. Using several measures to evaluate agreement, we explored whether patient characteristics, such as education and attitudes toward treatment, and patient-provider interaction styles, such as shared decision making, were associated with greater agreement on treatment goals and strategies. We then examined whether agreement was associated with higher patient assessments of their diabetes care self-efficacy and self-management.Results: Overall, agreement on top treatment goals and strategies was low (all kappa were less than 0.40). In multivariable analyses, however, patients with more education, greater belief in the efficacy of their diabetes treatment, and who shared in treatment decision making with their providers were more likely to agree with their providers on treatment goals or strategies. Similarly, physician reports of having discussed more content areas of diabetes self-care were associated with greater agreement on treatment strategies. In turn, greater agreement on treatment goals and strategies was associated both with higher patient diabetes care self-efficacy and assessments of their diabetes self-management.Conclusion: Although patients and their PCPs in general had poor agreement on goals and strategies for managing diabetes, agreement was associated with higher patient self-efficacy and assessments of their diabetes self-management. This supports the hypothesis that enhancing patient-provider agreement on both overall treatment goals and specific strategies to meet these goals may lead to improved patient outcomes.

Objective: The American Heart Association (AHA) recommends an automated external defibrillator (AED) be considered for a specific location if there is at least a 20% annual probability the device will be used. We sought to evaluate the cost-effectiveness of the AHA recommendation and of AED deployment in selected public locations with known cardiac arrest rates.Design: Markov Decision Model employing a societal perspective.Setting: Selected public locations in the United States.Patients: A simulated cohort of the American public.Intervention: Strategy 1: individuals experiencing cardiac arrest were treated by emergency medical services equipped with AEDs (EMS-D). Strategy 2: individuals were treated with AEDs deployed as part of a public access defibrillation program. Strategies differed only in the initial availability of an AED and its impact on cardiac arrest survival.Results: Under the base-case assumption that a deployed AED will be used on 1 cardiac arrest every 5 years (20% annual probability of AED use), the cost per quality-adjusted life year (QALY) gained is $30,000 for AED deployment compared with EMS-D care. AED deployment costs less than $50,000 per QALY gained provided that the annual probability of AED use is 12% or greater. Monte Carlo simulation conducted while holding the annual probability of AED use at 20% demonstrated that 87% of the trials had a cost-effectiveness ratio of less than $50,000 per QALY.Conclusions: AED deployment is likely to be cost-effective across a range of public locations. The current AHA guidelines are overly restrictive. Limited expansion of these programs can be justified on clinical and economic grounds. [ABSTRACT FROM AUTHOR]
