Background: Approximately 1.9 million Canadians are living with diabetes and this is estimated to increase by 75% over the next few decades. Pharmacists are front line primary healthcare professionals who see patients with diabetes frequently and in Alberta, they have been allowed to prescribe medications and order laboratory tests. As such, pharmacists could systematically identify poorly controlled diabetes patients and provide greater access to diabetes interventions to improve blood sugar control.

Objective: The aim of this study is to determine the effect of a community pharmacist intervention on blood sugar control in individuals with poorly controlled diabetes.

Project description:

100 adults with type 2 diabetes and uncontrolled blood sugar will be defined by the participating pharmacists. Blood sugar control is going to assessed using hemoglobin A1c test (a blood test to measure individual's blood sugar control over the last 3 months). This test requires obtaining a blood spot from the patient which will be obtained by pricking his/her fingertip. Based on the hemoglobin A1c test result the pharmacist will assess the patient's need for insulin glargine, if the patient needs insulin glargine the pharmacist is going to prescribe it for him/her and educate him/her on its use. Patients are going to be followed up closely by the pharmacists for 6 months with regular updates to the patients' family physicians. This multi-centre study should demonstrate pharmacists' ability to improve glycemic control and improve access to care.

Primary Outcome Measures:
  • The change in HbA1c from baseline to week 26 [ Time Frame: 6 months ]
    The change of the patients' HbA1c between the baseline and the 26 week visits

Secondary Outcome Measures:
  • Quality of life and patient satisfaction. [ Time Frame: 6 months ]
    Quality of life and patient satisfaction is going to be measured through using the questionnaires Audit of Diabetes-Dependent Quality of Life (ADDQoL), Diabetes Treatment Satisfaction Questionnaire and Diabetes Treatment Satisfaction Questionnaire change (DTSQ and DTSQc)

  • Proportion of patients achieving the target HbA1c [ Time Frame: 6 months ]
    Proportion of patients achieving HbA1c of ≤7.0% during follow-up

  • Type and degree of dosage changes in oral hypoglycemic agents [ Time Frame: 6 months ]
    The type and the degree of changes in the oral hypoglycemic dosing regimen

  • Persistence on insulin glargine [ Time Frame: 6 months ]
    Percentage of patients still taking insulin at the end of follow-up

  • Safety [ Time Frame: 6 months ]
    Number of hypoglycemic episodes; symptomatic confirmed and severe (i.e., Requiring the help from a third party), as defined by the CDA guidelines

  • Health economic evaluation [ Time Frame: 6 months ]
    Cost-effectiveness analyses from a healthcare payor (government) perspective. Costs will include pharmacist training, time spent with patients, pharmaceutical care processes (includes number of face-to-face meetings, time spent with the patient, number and duration of phone calls, number and type of testing per patient, equipment and testing costs, medication costs and out of pocket costs for patients). Clinical benefits will be estimated by modeling the A1C reduction with clinical trials estimates of event reductions

Arms Assigned Interventions
Insulin glargine
10 units at bedtime of insulin glargine will be prescribed to the patients who has HbA1c levels of 7.5-11%. Insulin glargine dose is going to be titrated by increments of 1 unit daily by the patient to achieve a morning fasting glucose of <=5.5mmol/L
