RESUMEN
PURPOSE: The purpose of the study was to assess the use of geofence technology to raise awareness of a dental clinic in rural North Carolina. METHODS: The catchment area of the dental clinic was defined by ZIP Codes. A geofence was identified, and cell phones within the perimeter were targeted for oral health message drops to occur over 3 months from April to June 2017. Surveys conducted twice, pre- and postintervention (message drop), evaluated change in community awareness of services available at the dental clinic. A cross-sectional analysis was used to measure the effect of the exposure to the geofence technology in survey respondents. FINDINGS: The survey included 200 participants (100 pre- and 100 postintervention). There were no significant differences in race or age for pre- and postintervention survey groups. The majority of respondents were American Indians (47.0% pre, 58.6% post) or black (28.8% pre, 25.5% post). There was a statistically significant improvement in awareness of the dental clinic (P = .045) from pre- to postintervention. A significant increase was also observed in the question related to dental visits by the respondent or family member of the respondent (from 6.5% to 15.0%, P = .04). A more modest improvement was found in questions related to the cost of dental care, type of insurance accepted, and services provided. CONCLUSION: Geofencing has the potential to increase awareness of health care services and ultimately increase the number of patients receiving care.
