 Q In vulnerable patients with poorly controlled type 2 diabetes mellitus, does a pharmacist led, primary care-based, disease management programme reduce cardiovascular risk factors and improve glycaemic control?

    METHODS

    Embedded ImageDesign:

    randomised controlled trial.

    Embedded ImageAllocation:

    {concealed*}.

    Embedded ImageBlinding:

    blinded (outcome assessors {and data collectors}†).

    Embedded ImageFollow up period:

    1 year.

    Embedded ImageSetting:

    University of North Carolina General Internal Medicine Practice, Chapel Hill, North Carolina, USA.

    Embedded ImagePatients:

    217 English speaking patients who were ⩾18 years of age, had a clinical diagnosis of type 2 diabetes, had poor glucose control (glycated haemoglobin [HbA1C] concentration ⩾8.0%), and had a life expectancy >6 months.

    Embedded ImageIntervention:

    primary care disease management programme (n = 112) or usual care (n = 110). The intervention consisted of usual care supplemented with intensive diabetes management; 3 clinical pharmacists who had training in outpatient disease management delivered intensive educational sessions and used evidence-based algorithms and proactive management of clinical parameters. See www.evidence-basedmedicine.com.

    Embedded ImageOutcomes:

    blood pressure (BP), HbA1C concentrations, aspirin use, and lipid concentrations.

    Embedded ImagePatient follow up:

    89% at 1 year (intention to treat analysis).

    MAIN RESULTS

    Systolic and diastolic BP, HbA1c concentrations, and aspirin use for cardiovascular risk prevention were more improved in patients who received the primary management programme than in those who received usual care (table). Cholesterol concentrations did not differ significantly between groups.

    CONCLUSION

    In vulnerable patients with poorly controlled type 2 diabetes mellitus, a pharmacist led, primary care-based, disease management programme reduced cardiovascular risk factors and improved glycaemic control.

    Commentary

    Rothman et al add to the literature on models of disease care management that empower health professionals other than primary care physicians with standardised guidelines and procedures. These professionals (pharmacists in this intervention) are responsible for tracking, coordinating, and implementing individualised patient care.

    What could limit adoption of these models? Firstly, as in other guideline implementation efforts,1,2 these models yield modest improvements. Secondly, if protocols are not sufficiently explicit and unambiguous, non-physician professionals may be challenged for extending their “scope of practice.” Thirdly, successful translation requires system redesign to support new roles and detailed protocols to ensure adequate implementation.

    Also, a wider scope of intervention, beyond monitoring and medication adjustment, may be more effective. Notably, supporting patient self efficacy and problem solving by using family and peer counselling and other psychosocial interventions can lead to healthier behaviours3 that may enhance patient outcomes.
