Addressing Diffusion of Responsibility and Prescribing Burden to Improve Use of Diabetes Medications

Study Overview
=================
Brief Summary
-----------------
This study will test the impact of addressing diffusion of responsibility with and without additional reduction of prescribing burden on SGLT-2i and GLP-1RAs prescribing compared to usual care. Population: MGH primary care physicians caring for at least 2 eligible patients. Eligible patients are individuals age18 years or older with type 2 diabetes and HbA1c >7.5% and a compelling indication for an SGLT-2i or GLP-1RA (including cardiovascular disease, kidney disease, heart failure, or obesity), who are not already prescribed one of these therapies. Intervention: PCPs will be randomized to one of three arms: 1) intervention to address diffusion of responsibility, 2) Intervention to address diffusion of responsibility with additional simplification of prescribing, 3) usual care.

Detailed Description
-----------------
This study will be conducted within MGH primary care. As with prior work, the investigators will use the hospital's EHR database, the Epic Enterprise Data Warehouse, to identify patients. Patients will be eligible if they are: adults 18-84 years of age with poorly controlled type 2 diabetes (defined as HbA1c >7.5% for ages 18-69 and >8.5% for ages 70-84) and a compelling indication for an SGLT-2i or GLP-1RA (including cardiovascular disease, kidney disease, heart failure, or obesity), who are not already prescribed one of these therapies. The investigators will exclude individuals with end stage renal disease, dementia, type I diabetes, or an EHR indicator of hospice care. The investigators will also exclude patients who are not on the MGH diabetes registry, because patients who are excluded from the registry typically have a clinical reason for alternative diabetes goals or care plans. PCPs caring for at least one eligible patient will be included in the trial. Eligible PCPs will be randomized to one of three arms: (1) intervention to address diffusion of responsibility, (2) intervention to address diffusion of responsibility plus additional simplification of the prescribing process, and (3) usual care. Providers randomized to arm 1, the intervention to address diffusion of responsibility will receive an email from a peer offering encouragement and support in prescribing SGLT-2is and GLP-1RAs that includes specific components designed to reduce diffusion of responsibility. The email will also contain a link to clinical and administrative information to support prescribing and an offer for direct support from the peer. Providers randomized to arm 2, the intervention addressing diffusion of responsibility and simplifying the prescribing process will receive the same contact addressing diffusion of responsibility as in arm 1, but they will additionally have access to an experienced administrative team for diabetes medication insurance authorization support. The primary outcome will be the rate of prescriptions for SGLT-2is and GLP-1RAs among eligible patients.

Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Patients: We will use EHR data to identify patients 18-84 years of age Diagnosed with type 2 diabetes Has poorly controlled diabetes (defined as HbA1c >7.5% for ages 18-69 and >8.5% for ages 70-84) Have a compelling indication for an SGLT-2i or GLP-1RA who are not already prescribed one of these therapies. A compelling indication includes individuals with cardiovascular disease, kidney disease, heart failure, or obesity. Physicians: Physicians will be included if they are Practicing in primary care at Massachusetts General Hospital Caring for at least 1 patient: (1) age 18-84, (2) diagnosed with type 2 diabetes, (3) has poorly controlled diabetes (defined as HbA1c >7.5% for ages 18-69 and >8.5% for ages 70-84) (4) has a compelling indication for an SGLT-2i or GLP-1RA (including cardiovascular disease, kidney disease, heart failure, or obesity), who are not already prescribed one of these therapies. Exclusion Criteria: Patients: We will exclude individuals with end stage renal disease, dementia, type I diabetes, or an EHR indicator of hospice care. We will also exclude patients who are not on the MGH diabetes registry, because patients who are excluded from the registry typically have a clinical reason for alternative diabetes goals or care plans. Physicians: - Providers will be excluded if they are involved in the design or conduct of this study (e.g. Drs. Haff and Horn, and the peer PCPs delivering the study intervention).

Arms and Interventions

| Experimental: Intervention to address diffusion of responsibility<br>PCPs will receive an email from a peer offering encouragement and support in prescribing SGLT-2is and GLP-1RAs that includes specific components designed to reduce diffusion of responsibility. Specifically, these elements will be adapted from interventions that mitigate diffusion of responsibility in other contexts, including: (1) assigning responsibility to individuals or smaller groups, (2) increased perceived harm of the situation to be addressed (3) highlighting competence to act, and (4) modeling the desired behavior. The email will also contain a link to clinical and administrative information to support prescribing and an offer for direct support from the peer. | Behavioral: Intervention to address diffusion of responsibility<br>* PCPs will receive an email from a peer offering encouragement and support in prescribing SGLT-2is and GLP-1RAs that includes specific components designed to reduce diffusion of responsibility.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Rate of prescriptions for SGLT-2i or GLP-1RA among eligible patients in each arm, compared across study arms | The study team will use electronic health record (EHR) prescribing data to identify prescriptions for SGLT-2i and GLP-1RA medications during the 6 month study intervention period among eligible patients. Rates of prescribing of these medications will be compared across study arms. | 6 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Rate of prescriptions for SGLT-2i or GLP-1RA medications among all patients with diabetes, compared across study arms | The study team will use EHR prescribing data to identify prescriptions for SGLT-2i and GLP-1RA medications during the 6 month study intervention period among all patients with diabetes cared for by study PCPs. Rates of prescribing of these medications will be compared across study arms. | 6 months | 
| Change in Hemoglobin A1c (A1c) over the 6-month intervention period among eligible patients, compared across study arms | The study team will use EHR data to calculate a change in A1c among eligible patients. The baseline A1c will be the last A1c measured within the 6-months prior to intervention start, and the follow-up A1c will be the last A1c measured in the 6-month intervention period. This change in A1c will be compared across study arms. | 6 months |
