Summary
Brief summary (as posted)
Primary care visits are a key aspect of clinical care focused on helping patients to close care gaps related to preventive care such as vaccination, diabetes testing, statin therapy and cancer screening. However, less than 50% of care gaps are closed during these visits and new approaches are needed to prime patients for a discussion during these visits. In this study, the study team will evaluate a health system initiative that uses text messaging to patients in days preceding a primary care visit to prime patients to be amenable to ordering of vaccination, diabetes testing, cancer screening, and statin prescribing.
