Trial summary

Background: Good blood pressure (BP) control among patients with diabetes is essential in preventing diabetes complications and has been found to be not only cost-effective but cost-saving. Nonetheless, over 25% of VA patients with diabetes do not have adequate BP control. Read more about this study

About this study

Official title: Adherence and Intensification of Medications: A Population-Based Clinical Pharmacists Implementation Study Among Hypertensive Diabetes Patients

Background: Good blood pressure (BP) control among patients with diabetes is essential in preventing diabetes complications and has been found to be not only cost-effective but cost-saving. Nonetheless, over 25% of VA patients with diabetes do not have adequate BP control. Among these poorly controlled patients, over 65% have problems with medication adherence or inadequate intensification of medications. We therefore propose a partnership with the VA Pharmacy Benefits Management (PBM) Office and VISN 11 to evaluate a tailored clinical pharmacist-based intervention to improve medication management, adherence and BP control.

Objectives: The specific objectives of this implementation study are: 1) To evaluate the effects of the intervention on blood pressure (primary outcome) and glycemic and lipid control (secondary outcomes); 2) To assess the impact of the intervention on patients' adherence to blood pressure, anti-hyperglycemic, and lipid-lowering regimens, and intensity of these regimens; 3) To evaluate the cost-effectiveness of the intervention compared to usual care; 4) To evaluate the level of attainment of intervention implementation, examine the process of intervention implementation, and determine the potential for sustainability.

Background: Good blood pressure (BP) control among patients with diabetes is essential in preventing diabetes complications and has been found to be not only cost-effective but cost-saving. Nonetheless, over 25% of VA patients with diabetes do not have adequate BP control. Among these poorly controlled patients, over 65% have problems with medication adherence or inadequate intensification of medications. We therefore propose a partnership with the VA Pharmacy Benefits Management (PBM) Office and VISN 11 to evaluate a tailored clinical pharmacist-based intervention to improve medication management, adherence and BP control.

Objectives: The specific objectives of this implementation study are: 1) To evaluate the effects of the intervention on blood pressure (primary outcome) and glycemic and lipid control (secondary outcomes); 2) To assess the impact of the intervention on patients' adherence to blood pressure, anti-hyperglycemic, and lipid-lowering regimens, and intensity of these regimens; 3) To evaluate the cost-effectiveness of the intervention compared to usual care; 4) To evaluate the level of attainment of intervention implementation, examine the process of intervention implementation, and determine the potential for sustainability.

Methods: In this cluster randomized implementation trial, we will proactively identify, using clinical automated data, all diabetes patients within 3 VA sites who have poor blood pressure control and either poor refill adherence or insufficient medication intensification. (NIDDK R18 funds 2 non-VA sites.) Adherence and treatment intensification patterns will also be evaluated for glycemia and lipids if either of these risk factors is poorly controlled. Clinical pharmacists, trained in motivational interviewing techniques and guided by computerized adherence modules, will identify barriers to medication adherence and provide adherence counseling. They will also be authorized to change and titrate medications following site-specific algorithms. Patients in the non-intervention (control) teams will receive usual care. Blood pressure control and refill adherence will be assessed 6-months after the end of the intervention period. We will also conduct a formative evaluation during the course of the study and assess implementation attainment and potential for dissemination.

Status: Data analysis complete. (Enrollment numbers are for VA and non-VA sites [control and intervention].)

The record says: finished, as of the sponsor's last update on 28 Apr 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Systolic Blood Pressure (time frame: 6 months prior to 6 months after the intervention period). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00495794, which also lists 6 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Apr 2015.
