Clinical Trial Summary

This is a single site, pre-post pilot study. The objective is to evaluate the acceptability and feasibility of a primary care hypoglycemia prevention program for patients taking hypoglycemia-causing medications. The study will also evaluate relevant process outcomes and clinical outcomes for refining the intervention and planning for a larger efficacy trial.

Related Conditions & MeSH terms

• Diabetes Mellitus
• Hypoglycemia

Intervention

Other:
• Patient Group (Hypoglycemia Prevention Program)
The Hypoglycemia Prevention Program: The patient hypoglycemia profile - this is a set of survey questions about hypoglycemia and related aspects of diabetes care. The questions will be administered as an Epic MyChart message sent to the patient in the week prior to the clinic visit, and in the clinic waiting room on a tablet immediately prior to the patient's primary care provider visit.
• Primary Care Physician Group
The provider hypoglycemia toolkit - this is the report from the patient hypoglycemia profile, which triggers a set of hypoglycemia prevention tools and patient education materials as appropriate. Primary Care Providers will not be exposed to the intervention until all of their patients have completed the Baseline Clinic Visit.
• Clinic Staff Group
Clinic staff will provide the tablet to the participant immediately prior to the patient's primary care provider visit.
