Background and study aims
Diabetes is one of the common chronic health problems that affects many people in Singapore. Uncontrolled diabetes, where patients have persistently high levels of sugar in the blood, can harm important organs such as heart and the kidneys, and the management of diabetes-related complications is costly. People with diabetes, however, can still live a long and healthy life if their diabetes is well-controlled. Well-controlled diabetes requires healthy diet and active lifestyle, and optimal use of medications is also essential in ensuring timely control of diabetes. The purpose of this study is to find out the value of a new care approach which involves pharmacists, in addition to nurses, dieticians and other healthcare professionals, to support physicians in caring for patients with uncontrolled diabetes.
Who can participate?
Patients aged at least 21 years with uncontrolled type 2 diabetes, and other uncontrolled co-morbidities (other health conditions).
What does the study involve?
Patients are randomly allocated to one of two groups. Those in group 1 receive the active involvement of the pharmacist in drug optimization. Referrals to nurses and dieticians are actively made by the pharmacist and vice versa as required. Patients in group 2 (the control group) receive their usual or conventional care from the physician with as needed referral at the discretion of the physician to the nurses and dieticians. These patients are seen by different physicians at each visit, and pharmacists are not involved in drug optimization except for dispensing.
What are the possible benefits and risks of participating?
Patients who participate in this study may reasonably expect to benefit from the pharmacist-involved healthcare model in that the pharmacists will be able to assist patients in reviewing and explaining their blood glucose results, optimize medications, provide a cost-effective medication regimen, assist in setting goals to improve patients' conditions, answer questions related to medications and empower patients' knowledge on medications. There will not be any possible risks or side effects for participating in this study. Because the involvement of pharmacist is to provide an added value, patients' standard of care or routine care is still being preserved.

| Scientific title | The effectiveness of pharmacist-involved collaborative care model in the management of patients with diabetes mellitus in Singapore |
| Study objectives | The hypothesis of this study is that patients with diabetes under pharmacist-involved collaborative care will have greater improvements in all the clinical, humanistic and economic outcomes assessed than those under the conventional care. |
| Ethics approval(s) | National University of Singapore Institutional Review Board and National Healthcare Group Domain Specific Review Board, 20/12/2012, 2012/01037 |
| Health condition(s) or problem(s) studied | Type 2 diabetes and other chronic comorbidities such as hypertension and dyslipidemia |
| Intervention | Eligible patients will be randomized into the intervention or control arms: 1. Patients assigned to the intervention arm will receive active involvement of the pharmacist in drug optimization. The clinical interventions carried out by the pharmacist include but are not limited to counseling patients about drug therapy, performing simple physical assessments, ordering pertinent follow-up visits and laboratory tests on behalf of the physicians, and initiating, titrating, and terminating medications per clinical protocol and under the supervision of the physicians as appropriate. As needed, referrals to nurses and dieticians will also be actively made by the pharmacist and vice versa. The pharmacist will schedule clinic appointments approximately every six weeks, with a total of 4 pharmacist visits in the 6-month follow-up period. If the patient’s diabetes is well-controlled, i.e. with stable improvements in clinical measures, the pharmacist may replace one or two clinic visits with telephone counseling at his/her discretion. 2. Patients assigned to the control arm will receive the usual or conventional care from the physician with as needed referral at the discretion of the physician to the nurses for soft skill-related diabetes counseling and dietitians for diet control. These patients may be seen by different physicians at each visit, and pharmacists will not be involved in drug optimization except for dispensing. |
