Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Approximately 1.9 million Canadians are living with diabetes. Estimates are that this number will increase by 75% over the next few decades. Glycemic control in patients with type 2 diabetes mellitus is poor, and poorly controlled patients contribute significantly to the cost of primary health care in Canada. 10% of all acute care hospital admissions in 2006 were attributed to diabetes and its complications.
As type 2 diabetes is a progressive disease, most patients with type 2 diabetes will eventually require insulin. In patients who present with type 2 diabetes and a HbA1C over 9%, insulin can be started immediately, however, historically physicians generally perceive their to be patient difficulties in starting insulin therapy.
INSIGHT demonstrated improved glycemic control with addition of insulin glargine to oral hypoglycemic agents in patients with type 2 diabetes. However, physicians are often reluctant to initiate insulin in these patients. In addition, physicians do not have a system to systematically identify potential candidates for insulin add-on therapy
Pharmacists are front line primary care professionals who see patients with diabetes more frequently than family physicians and as such, could systematically and proactively identify patients with type 2 diabetes with poor glycemic control as a public health approach to chronic disease management. This approach has been used successfully by our group in the past with dyslipidemia and hypertension management involving patients with diabetes.
The scope of practice for pharmacists is changing, with legislation in Alberta (and soon other provinces) allowing pharmacists to prescribe Schedule I medications and order laboratory tests. As such, there is an opportunity to provide greater access, convenience and improved glycemic control by engaging community pharmacists and their patients.
PRIMARY OBJECTIVE: To determine the effect of a community pharmacist prescribing intervention on glycemic control in patients with poorly controlled type 2 diabetes.
SECONDARY OBJECTIVES:
* To determine the effects of pharmacist-directed diabetes care focusing on glycemic control on:
* patient satisfaction
* quality of life
* dosage changes of oral agents
* persistence on insulin glargine and the end of follow-up
* hypoglycemic episodes
* To conduct a health economic assessment of the costs and benefits of the intervention
METHODS:
Design: multicentre pragmatic before-after design trial
Setting: Ten community pharmacies in Alberta for recruitment and follow-up, engaging both patients and family physicians
• participating pharmacists will have additional prescribing authorization. For pharmacists not having additional prescribing authorization, we will facilitate their application as done in the rural RxACTION study.
Recruitment: Pharmacists will systematically identify potential candidates by inviting all patients with type 2 diabetes receiving oral hypoglycemic medications to check their HbA1c using a point of care test. HbA1c is going to be measured in the pharmacy. The patient has to sign the first stage consent form in order to get his/her HbA1c measured. After signing the consent form, the patient's HbA1c will be measured using a digital meter which requires a blood spot which will be gained by pricking the patient's fingertip. If the result of HbA1c test is normal the patient will be given his/her result and told to keep up the good work. If the result of HbA1c test is high (7.5-11 %) and the patient meets the other inclusion criteria for the study the patient will be asked if he/she wants to participate in the study. If the patient agrees on participating in the study he/she will be asked to sign the second stage consent form. After signing the consent form the patient will be started on insulin glargine at bedtime and will be taught how to use the insulin pen. If HbA1c is \> 11% the patient will be assessed by the study investigators, treatment recommendations will be checked and will be referred to his/her family physician.
Follow-up: Patients will be followed at 2, 4, 8, 14, 20, and 26 weeks to capture adverse events, adherence to the insulin regimen, fasting blood sugars (measured by the patient), insulin dose and titration. HbA1c will be measured at baseline and then at week 14 visit and week 26. Interim telephone follow-up may be performed at the discretion of the pharmacist investigator, however telephone follow-up cannot be used for 2 consecutive visits, nor for week 14 or 26 visits. Fasting glucose will be measured at the discretion of the pharmacist and patients will monitor their blood glucose at home and record in a standard patient diary.
After each follow up study the pharmacists is going to inform the patient's family physician if there were any changes in the patient's treatment regimen and also about the results of any tests conducted.
One year after the final follow up visit, the pharmacy is going to receive a phone call from the study investigators to check if the patient is still taking insulin.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
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
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
