TDM: Titrated Disease Management for Patients With Hypertension
Study Details
Study Description
Brief Summary
This randomized clinical trial examines whether programs aimed at matching resources to patient hypertension (i.e. high blood pressure) control lead to greater reduction in systolic blood pressure (top number of blood pressure reading) than simply having maintenance phone calls in addition to usual care. Answering this question will provide important evidence concerning the overall goal of sustained long-term implementation of the disease management programs as part of patient aligned care teams in the Veterans Affairs and other healthcare systems.

Detailed Description
Project Objectives: The investigators are conducting a two-arm 18-month randomized clinical trial for patients with pharmaceutically treated hypertension for which systolic BP is not controlled (>/=140 mmHg for non-diabetic or >/=130 mmHg for diabetic patients). The primary aim will be to compare two treatment arms/strategies in terms of impact on systolic BP control: Arm 1 - An intervention arm using titrated disease management in which patients' hypertension control, assessed at baseline, 6 and 12 months, will be used to decide the resource intensity of strategies: 1) Medium/level 1 resource intensity strategy: a registered nurse will provide monthly tailored behavioral support telephone calls + home BP monitoring; 2) High/level 2 resource intensity strategy: a pharmacist will provide monthly tailored behavioral support telephone calls + home BP monitoring + pharmacist-directed medication management; and 3) Booster (low) resource intensity strategy: a license practice nurse (LPN) will provide bi-monthly, non-tailored behavioral support telephone calls to patients whose systolic BP comes under control. Arm 2 - A control arm, in which an LPN will provide bi-monthly non-tailored behavioral support telephone calls (same procedures as the booster (low) resource intensity strategy component of the titrated intervention).
Study Design
Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Titration Intervention The intervention arm includes three levels of resource intensity targeted to improve patients' systolic blood pressure (SBP) [top number of blood pressure measurement]. Medium/level 1 resource intensity: a registered nurse (RN) will provide monthly tailored behavioral support telephone calls + home BP monitoring. High/level 2 resource intensity: a pharmacist will provide monthly tailored behavioral support telephone calls + home BP monitoring + pharmacist-directed medication management. Booster (low) resource intensity: a licensed practical nurse (LPN) will provide non-tailored behavioral support telephone calls every two months to patients whose SBP comes under control. |
Behavioral: Booster/ low resource
A LPN will provide behavioral support telephone calls that do not include goal setting and directed problem solving every two months.
Other Names:
Behavioral: Medium/Level 1 resource intensity
Monthly tailored RN delivered calls + home BP monitoring.
Other Names:
Behavioral: High/Level 2 resource intensity
Pharmacist delivered telephone behavioral self-management support + Home BP monitoring with feedback to pharmacist + Algorithmic medication changes directed by pharmacist (with physician backup).
Other Names:

Outcome Measures
Primary Outcome Measures
- Systolic Blood Pressure [Baseline]
Continuous change in systolic blood pressure was measured as the primary outcome. Mean systolic blood pressure was calculated by the average of 3 blood pressure measurements collected at the baseline study visits.
- Systolic Blood Pressure [6 months]
Continuous change in systolic blood pressure was measured as the primary outcome. Mean systolic blood pressure was calculated by the average of 3 blood pressure measurements collected at the 6- month study visits.
- Systolic Blood Pressure [12 months]
Continuous change in systolic blood pressure was measured as the primary outcome. Mean systolic blood pressure was calculated by the average of 3 blood pressure measurements collected at the12-month study visits.
- Systolic Blood Pressure [18 months]
Continuous change in systolic blood pressure was measured as the primary outcome. Mean systolic blood pressure was calculated by the average of 3 blood pressure measurements collected at the18- month study visits.
Secondary Outcome Measures
- Number of Participants With Hypertension Control [Baseline]
The investigators examined the difference in the degree of systolic BP control over the 18 months of the study between the intervention and control arms. Control was defined as SBP < 130mmHg for hypertensive patients with diabetes and < 140mmHg for patients without diabetes. Mean systolic blood pressure was calculated by the average of 3 blood pressure measurements collected at the baseline study visit.
- Number of Participants With Hypertension Control [6 months]
The investigators examined the difference in the degree of systolic BP control over the 18 months of the study between the intervention and control arms. Control was defined as SBP < 130mmHg for hypertensive patients with diabetes and < 140mmHg for patients without diabetes. Mean systolic blood pressure was calculated by the average of 3 blood pressure measurements collected at the 6-month study visit.
- Number of Participants With Hypertension Control [12 months]
The investigators examined the difference in the degree of systolic BP control over the 18 months of the study between the intervention and control arms. Control was defined as SBP < 130mmHg for hypertensive patients with diabetes and < 140mmHg for patients without diabetes. Mean systolic blood pressure was calculated by the average of 3 blood pressure measurements collected at the 12-study visit.
- Number of Participants With Hypertension Control [18 months]
The investigators examined the difference in the degree of systolic BP control over the 18 months of the study between the intervention and control arms. Control was defined as SBP < 130mmHg for hypertensive patients with diabetes and < 140mmHg for patients without diabetes. Mean systolic blood pressure was calculated by the average of 3 blood pressure measurements collected at the18- month study visit.
- Cost Effectiveness [Over 18 months of study intervention]
One of our secondary research questions was: "If the intervention results in greater reduction in SBP than the control group, is it cost effective?" Intervention results did not show statistically significant differences between arms, therefore cost effectiveness analysis was not appropriate. While cost effectiveness was not analyzed because it was a null trial, the investigators would have used resource utilization and cost data from VA data sets to measure VA outpatient and inpatient utilization and costs by arms over 18 months. The investigators would have examined hypertension-related outpatient pharmacy prescription counts and costs in order to compare them to total outpatient pharmacy costs and the investigators would have examined inpatient utilization and costs.
- Number of Participants Who Did Not Achieve Medication Adherence [Baseline]
The investigators assessed adherence using patient self-report on a modified Morisky scale using 4 items: Do you ever forget to take your blood pressure medicine? Are you careless at times about taking your blood pressure medicine? When you feel better do you sometimes stop taking you blood pressure medicine? Sometimes if you feel worse when you take your blood pressure medicine, do you stop taking it? The scale is a Yes(0) or No (1) answer. A response of YES to any one of the 4 items indicated non-adherence, and responses of all no indicated adherence. The numbers in the descriptive tables reflect number non-adherent.

Title | Number of Participants With Hypertension Control |
---|---|
Description | The investigators examined the difference in the degree of systolic BP control over the 18 months of the study between the intervention and control arms. Control was defined as SBP < 130mmHg for hypertensive patients with diabetes and < 140mmHg for patients without diabetes. Mean systolic blood pressure was calculated by the average of 3 blood pressure measurements collected at the18- month study visit. |
Time Frame | 18 months |
Outcome Measure Data
Analysis Population Description |
---|
37 out of the 192 participants in the Titration Intervention group and 33 out of the 193 in the LPN control group had missing blood pressure measurement at 18 months due to not completing the assessment. |

Arm/Group Description | The intervention arm includes three levels of resource intensity targeted to improve patients' systolic blood pressure (SBP) [top number of blood pressure measurement]. Medium/level 1 resource intensity: a registered nurse (RN) will provide monthly tailored behavioral support telephone calls + home BP monitoring. High/level 2 resource intensity: a pharmacist will provide monthly tailored behavioral support telephone calls + home BP monitoring + pharmacist-directed medication management. Booster (low) resource intensity: a licensed practical nurse (LPN) will provide non-tailored behavioral support telephone calls every two months to patients whose SBP comes under control. Booster/ low resource: A LPN will provide behavioral support telephone calls that do not include goal setting and directed problem solving every two months. | A LPN will provide behavioral support telephone calls that do not include goal setting and directed problem solving every two months (identical to booster (low) resource intensity component of the titrated intervention).

Title | Cost Effectiveness |
---|---|
Description | One of our secondary research questions was: "If the intervention results in greater reduction in SBP than the control group, is it cost effective?" Intervention results did not show statistically significant differences between arms, therefore cost effectiveness analysis was not appropriate. While cost effectiveness was not analyzed because it was a null trial, the investigators would have used resource utilization and cost data from VA data sets to measure VA outpatient and inpatient utilization and costs by arms over 18 months. The investigators would have examined hypertension-related outpatient pharmacy prescription counts and costs in order to compare them to total outpatient pharmacy costs and the investigators would have examined inpatient utilization and costs. |

Description | The investigators assessed adherence using patient self-report on a modified Morisky scale using 4 items: Do you ever forget to take your blood pressure medicine? Are you careless at times about taking your blood pressure medicine? When you feel better do you sometimes stop taking you blood pressure medicine? Sometimes if you feel worse when you take your blood pressure medicine, do you stop taking it? The scale is a Yes(0) or No (1) answer.
