    A Remote Program for Navigator‐ and Pharmacist‐Led Management of Obesity Medications in Adults: Rationale, Design, and Implementation

    by Bryn Falahee, John W. Ostrominski, Kavishwar B. Wagholikar, Ozan Unlu, David Zelle, Sanjay Kumar, Daniel Gabovitch, Michela Tucci, Austen Smith, Hunter Nichols, et al.

    Objective: Remote interventions leveraging team‐based care may ameliorate persistent gaps in obesity medication implementation, but prospective studies are lacking. In this paper, the design, enrollment, and implementation of a remote intervention for obesity medications are described. Methods: The Supplementary Anti‐Obesity Medication Integration into a Longitudinal Obesity (SAIL) study is a fully remote program with pharmacist‐ and navigator‐led obesity medication implementation. Individuals with body mass index (BMI)‐defined overweight or obesity receiving a digital lifestyle intervention were recruited for participation in SAIL via a survey. Effectiveness outcomes included obesity medication prescription and body weight change at 6 months. Focus groups were conducted with study staff after program completion to identify implementation barriers and solutions. Results: Between June 2023 and September 2024, 200 patients responded to the survey, of which 99 were eligible. Of these, 75 enrolled in SAIL (mean age, 50 ± 12 years; 83% women; mean BMI 36 ± 6 kg/m 2 ). Focus groups identified multiple implementation challenges and opportunities, including medication access, insurance coverage, and patient education. Addressing misinformation, frequent patient engagement, and program flexibility emerged as unique strengths of SAIL. Conclusions: The final results of SAIL will inform the effectiveness of remote, algorithm‐driven, navigator‐ and pharmacist‐led programs for obesity medication prescription and management.

  • The Long-Term Blood Pressure Trends Following a Remote Hypertension Intervention: A Secondary Analysis of the Digital Care Transformation - Remotely Delivered Hypertension Management Program

    BACKGROUND: Hypertension is a major cardiovascular risk factor, yet traditional care often results in suboptimal blood pressure (BP) control at the population level. We implemented a remote hypertension management program that monitored home BP and titrated medications per algorithm. This study assessed the program’s long-term effects by examining participants’ office BP up to 42 months post-enrollment. METHODS: Participants of the remote hypertension program were categorized into 4 groups: (1) enrolled-maintenance (achieved goal home BP of ≤130/80 mm Hg), (2) enrolled–early exit (left before achieving goal BP), (3) education-only (lifestyle modifications and medications compliance), and (4) white coat hypertension group (high office BP but normal home BP). Office BP readings of participants were collected up to 42 months post-enrollment. A linear mixed-effects regression model estimated mean BP levels and studied factors associated with above-goal systolic BP in the maintenance group. RESULTS: Office BP readings from 3601 participants (mean age, 61±11 years; 57% female; 60% white; 52% atherosclerotic cardiovascular disease) were extracted from electronic health records and analyzed. All groups sustained office BP below their qualifying values ( P 50 years was associated with above-goal systolic BP in the maintenance group. CONCLUSIONS: Participants who achieved BP control through the remote hypertension program maintained goal systolic BP in 90% of cases up to 42 months post-enrollment. These findings highlight the long-term benefits of remote, intensive management programs for effective hypertension control.


  • Randomized Evaluation of a Remote Management Program to Improve Guideline-Directed Medical Therapy: The DRIVE Trial

    by Alexander J. Blood, Lee-Shing Chang, Shahzad Hassan, Jacqueline Chasse, Gretchen Stern, Daniel Gabovitch, David Zelle, Caitlin Colling, Samuel J. Aronson, Christian Figueroa, et al.

    BACKGROUND: Several SGLT2i (sodium-glucose transport protein 2 inhibitors) and GLP1-RA (glucagon-like peptide-1 receptor agonists) reduce cardiovascular events and improve kidney outcomes in patients with type 2 diabetes; however, utilization remains low despite guideline recommendations. METHODS: A randomized, remote implementation trial in the Mass General Brigham network enrolled patients with type 2 diabetes with increased cardiovascular or kidney risk. Patients eligible for, but not prescribed, SGLT2i or GLP1-RA were randomly assigned to simultaneous virtual patient education with concurrent prescription of SGLT2i or GLP1-RA (ie, Simultaneous) or 2 months of virtual education followed by medication prescription (ie, Education-First) delivered by a multidisciplinary team driven by nonlicensed navigators and clinical pharmacists who prescribed SGLT2i or GLP1-RA using a standardized treatment algorithm. The primary outcome was the proportion of patients with prescriptions for either SGLT2i or GLP1-RA by 6 months. RESULTS: Between March 2021 and December 2022, 200 patients were randomized. The mean age was 66.5 years; 36.5% were female, and 22.0% were non-White. Overall, 30.0% had cardiovascular disease, 5.0% had cerebrovascular disease, and 1.5% had both. Mean estimated glomerular filtration rate was 77.9 mL/(min‧1.73 m 2 ), and mean urine/albumin creatinine ratio was 88.6 mg/g. After 2 months, 69 of 200 (34.5%) patients received a new prescription for either SGLT2i or GLP1-RA: 53.4% of patients in the Simultaneous arm and 8.3% of patients in the Education-First arm ( P P P P <0.001). CONCLUSIONS: In this randomized trial, a remote, team-based program identifies patients with type 2 diabetes and high cardiovascular or kidney risk, provides virtual education, prescribes SGLT2i or GLP1-RA, and improves guideline-directed medical therapy. These findings support greater utilization of virtual team-based approaches to optimize chronic disease management.

    Remote Cardiovascular Hypertension Program Enhanced Blood Pressure Control During the COVID‐19 Pandemic

    by Simin Gharib Lee, Alexander J. Blood, Christopher P. Cannon, William J. Gordon, Hunter Nichols, David Zelle, Benjamin M. Scirica, Naomi D. L. Fisher

    Background: The COVID‐19 pandemic disrupted traditional health care; one fallout was a drastic decrease in blood pressure (BP) assessment. We analyzed the pandemic's impact on our existing remote hypertension management program's effectiveness and adaptability. Methods and Results: This retrospective observational analysis evaluated BP control in an entirely remote management program before and during the pandemic. A team of pharmacists, nurse practitioners, physicians, and nonlicensed navigators used an evidence‐based clinical algorithm to optimize hypertensive treatment. The algorithm was adapted during the pandemic to simplify BP control. Overall, 1256 patients (605 enrolled in the 6 months before the pandemic shutdown in March 2020 and 651 in the 6 months after) were a median age of 63 years old, 57% female, and 38.2% non‐White. Among enrolled patients with sustained hypertension, 51.1% reached BP goals. Within this group, rates of achieving goal BP improved to 94.6% during the pandemic from 75.8% prepandemic ( P P P P P <0.0001), compared with the prepandemic period. Conclusions: A remote clinical management program was successfully adapted and delivered significant improvements in BP control and increased home BP monitoring despite a nationally observed disruption of traditional hypertension care. Such programs have the potential to transform hypertension management and care delivery.
