Brief summary

The central objective of this proposal is to rigorously compare two strategies designed to improve BP control in primary care practices serving rural Southeastern African Americans with low socioeconomic status (SES) living in the Black Belt. In year 1, we're engaging community members (community members who have experience being community peer advisors or have high blood pressure) to develop the study interventions and protocols. In years 2-5, the investigators will test the interventions. Year 2-5, Aim 3: Enroll 80 practices and 25 African American patients with uncontrolled HTN at each practice (total n=2000) in a cluster-randomized, controlled, 4-arm pragmatic implementation trial to evaluate the three multi- component, multi-level functional interventions finalized in the UH2 phase compared with enhanced usual care. The study's 4 arms are: 1. Enhanced Usual Care: Practices are provided with educational materials and tools to enhance patient care 2. Peer Coaching: Patients enrolled in these practices will be matched with a peer coach. The peer coach helps the patient to set goals around self-management, including medications, home monitoring, and diet and exercise, and she helps the patient to strategize how to accomplish the goals, using motivational interviewing techniques 3. Practice Facilitation: Practices randomized to this arm will work with a practice facilitator. Practice facilitation is a highly customized, staged approach to helping a practice to implement process and structural changes to enhance the quality of care and improve patient and staff satisfaction 4. Peer coaching and practice facilitation: Practices randomized to this arm will receive both the peer coach intervention and the practice facilitation intervention. Practice facilitators and peer coaches will receive the same training for this hybrid intervention, but the practice facilitator change packet will add examples of activities that integrate peer coaches.

Interventions

ractices that are randomized to the practice facilitation arm will work with a practice facilitator that will help practice staff for 15 months to make practice level changes to improve hypertension control. Practice facilitation is a highly customized, staged approach to helping a practice to implement process and structural changes to enhance the quality of care and improve patient and staff satisfaction

BEHAVIORALPeer Coach

Participants enrolled from practices that are randomized to the peer coach arm will be matched with peer advisors who will work with the participants for 12 months.

BEHAVIORALEnhanced usual care

Practices in the usual enhanced care arm will receive a blood pressure medication algorithm developed using national guidelines and content experts on our study team. Practices will be provided the Joint National Committee (JNC) recommended protocol to measuring blood pressures. Practices will receive a laptop workstation that has access to the Patient Activated Learning System - an online education video system.

MeasureTime frameDescription
Change in the Mental Component Summary Score (MCS) From the Short Form 12 (SF12)12 monthsChange in health related quality of life measured using self report scale Short form-12. Six questions comprise the MCS. Of the six questions, two questions are dichotomous as yes or no. One question ranges on a 5 point Likert scale from all of the time to none of the time. Three questions range on a 6 point Likert scale from all of the time to none of the time. Different weights are applied to each item to result in a score ranging from 0-100 with higher scores indicating higher mental functioning.
Self-reported ED Visit or Evidence of an ED Visit in Chart Review Between 6 Months and 12 Monthsbetween 6 months to 12 monthOutcome was defined by self-reported question (yes/no) or chart review. Those who reported yes to the question, In the past 6 months have you been seen in an ER/ED but not admitted overnight were considered having the outcome. Data collectors looked for ED visits in patient's charts between their 6 month and 12 month follow-up. The outcome measure timeframe is between 6 months and 12 month follow-up.
Self-reported Hospitalization or Evidence of Hospitalization in Chart Review Between Baseline and 6 Monthsbetween baseline to 6 monthsOutcome was defined by self-reported question (yes/no) or chart review. Those who reported yes to the question, In the past 6 months have you been hospitalized overnight? were considered having the outcome. Data collectors looked for hospitalization in patient's charts between baseline and 6 month visit. The outcome measure timeframe is between baseline and 6 months.
Self-Reported Hospitalization or Evidence of Hospitalization in Chart Review Between 6 Month and 12 Monthbetween 6 month to 12 monthOutcome was defined by self-reported question (yes/no) or chart review. Those who reported yes to the question, In the past 6 months have you been hospitalized overnight? were considered having the outcome. Data collectors looked for hospitalizations in patient's charts between their 6 month and 12 month follow-up. The outcome measure timeframe is between 6 months and 12 month follow-up.
Change in Perceived Stress12 monthsThe 4-item Cohen perceived stress scale that are measured on a 5-point scale (0 = never, 1= almost never, 2 = sometimes, 3 = fairly often and 4- very often). Items 2 and 3 are reverse coded and then all for items are summed to created a total score that ranges from 0 -16. A higher score is negative indicating greater perceived stress.
Change in Systolic Blood Pressure Between Baseline and 12 Months12 monthsChange in systolic blood pressure between baseline and 12 months, which is analyzed by subtracting the baseline systolic BP from the 12 month systolic BP.
Change in Satisfaction With Chronic Illness Care Between Baseline and 12 Months12 monthsPatient Assessment of Care for Chronic Conditions (PACIC) measures how patients perceive their chronic condition(s) are being managed by their health care team. Patients fill out a survey of 20 questions regarding the care of their chronic condition(s) over the last 12 months. Used a Likert scale from 1-5, where 1 signifies None of the time and 5 signifying Always. PACIC was scored by summing participants' responses across all 20 items then dividing by 20. This score was calculated at baseline and 12 months follow-up. A change in score for each participant was created by subtracting the 12 months follow-up PACIC score from the baseline PACIC score.
Change in Physical Component Summary Score (PCS) of the Short Form 12 (SF12)12 monthsChange in health related quality of life measured using self report scale Short form-12. Six questions comprise the PCS. Of the six questions, one question ranges on a 5 point Likert scale from excellent to poor. Two questions range on a 3 point Likert scale from a lot to not at all. Two questions are dichotomous as yes or no. One question ranges on a 5 point Likert scale from extremely to not at all. Different weights are applied to each item to results in scores ranging from 0-100 with higher scores indicating higher functioning.
Self-reported ED Visit or Evidence of an ED Visit at Chart Review Between Baseline and 6 Monthsbetween baseline and 6 monthsOutcome was defined by self-reported question (yes/no) or chart review. Those who reported yes to the question, In the past 6 months have you been seen in an ER/ED but not admitted overnight were considered having the outcome. Data collectors looked for ED visits in patient's charts between baseline and 6 month visit. The outcome measure timeframe is between baseline and 6 months.

MeasureTime frameDescription
Change in Perceived Emotional Support12 monthsWe measured change perceived emotional support between baseline and 12 months using the Patient Reported Outcomes Measurement Information System (PROMIS) short-form social functioning scale. To each question subjects were asked to respond with never, rarely, sometimes, usually, or always. A numerical value was attached to each of these answers, ranging from 1 (never) to 5 (always). The T-score rescales the raw score into a standardized score with a mean of 50 and a standard deviation (SD) of 10. Raw scores were translated to standardized t-scores to allow comparison of our sample to the U.S population. Raw scores ranged from 4-20 and scale scores ranged from 25.7-62 with higher scores indicating greater emotional support.
Change in Social Isolation12 monthsWe measured change in isolation between baseline and 12 months using the Social Isolation Patient Reported Outcomes Measurement Information System (PROMIS) short-form social functioning scale. To each question subjects were asked to respond with never, rarely, sometimes, usually, or always. A numerical value was attached to each of these answers, ranging from 1 (never) to 5 (always). Raw scores were translated to standardized t-scores to allow comparison of our sample to the U.S population. The T-score rescales the raw score into a standardized score with a mean of 50 and a standard deviation (SD) of 10. The scale is comprised of 4 items. Raw scores range from 0-20 and scale scores range from 34.8-74.2. Higher scores indicate greater isolation.
Change in Instrumental Support12 monthsWe measured change in perceived instrumental support between baseline and 12 months using the Patient Reported Outcomes Measurement Information System (PROMIS) short-form social functioning scale. To each question subjects were asked to respond with never, rarely, sometimes, usually, or always. A numerical value was attached to each of these answers, ranging from 1 (never) to 5 (always). Raw scores were translated to standardized t-scores to allow comparison of our sample to the U.S population. ). The T-score rescales the raw score into a standardized score with a mean of 50 and a standard deviation (SD) of 10. Raw scores ranged from 4-20. Scale scores ranged from 29.3-69.3 with a higher score indicating greater instrumental support.

Change in Satisfaction With Chronic Illness Care Between Baseline and 12 Months

Patient Assessment of Care for Chronic Conditions (PACIC) measures how patients perceive their chronic condition(s) are being managed by their health care team. Patients fill out a survey of 20 questions regarding the care of their chronic condition(s) over the last 12 months. Used a Likert scale from 1-5, where 1 signifies None of the time and 5 signifying Always. PACIC was scored by summing participants' responses across all 20 items then dividing by 20. This score was calculated at baseline and 12 months follow-up. A change in score for each participant was created by subtracting the 12 months follow-up PACIC score from the baseline PACIC score.

Outcome was defined by self-reported question (yes/no) or chart review. Those who reported yes to the question, In the past 6 months have you been hospitalized overnight? were considered having the outcome. Data collectors looked for hospitalization in patient's charts between baseline and 6 month visit. The outcome measure timeframe is between baseline and 6 months.

Time frame: between baseline to 6 months

Population: There are 4 arms in this study. Arm one is enhanced usual care. Arm 2 is practice facilitation. Arm 3 is peer coaching. In arm 4 practices received practice facilitation and participants received peer coaching.

Change in Instrumental Support

We measured change in perceived instrumental support between baseline and 12 months using the Patient Reported Outcomes Measurement Information System (PROMIS) short-form social functioning scale. To each question subjects were asked to respond with never, rarely, sometimes, usually, or always. A numerical value was attached to each of these answers, ranging from 1 (never) to 5 (always). Raw scores were translated to standardized t-scores to allow comparison of our sample to the U.S population. ). The T-score rescales the raw score into a standardized score with a mean of 50 and a standard deviation (SD) of 10. Raw scores ranged from 4-20. Scale scores ranged from 29.3-69.3 with a higher score indicating greater instrumental support.

Time frame: 12 months

Population: There are 4 arms in this study. Arm one is enhanced usual care. Arm 2 is practice facilitation. Arm 3 is peer coaching. In arm 4 practices received practice facilitation and participants received peer coaching.

Change in Social Isolation

We measured change in isolation between baseline and 12 months using the Social Isolation Patient Reported Outcomes Measurement Information System (PROMIS) short-form social functioning scale. To each question subjects were asked to respond with never, rarely, sometimes, usually, or always. A numerical value was attached to each of these answers, ranging from 1 (never) to 5 (always). Raw scores were translated to standardized t-scores to allow comparison of our sample to the U.S population. The T-score rescales the raw score into a standardized score with a mean of 50 and a standard deviation (SD) of 10. The scale is comprised of 4 items. Raw scores range from 0-20 and scale scores range from 34.8-74.2. Higher scores indicate greater isolation.

Time frame: 12 months

Population: There are 4 arms in this study. Arm one is enhanced usual care. Arm 2 is practice facilitation. Arm 3 is peer coaching. In arm 4 practices received practice facilitation and participants received peer coaching.
