A Spanish-language educational intervention to enhance diabetes outcomes among existing continuous glucose monitor users in a federally qualified health care center

ABSTRACT: Latinx adults with type 2 diabetes (T2D) experience worse glycemic outcomes. Although continuous glucose monitors (CGMs) improve glycemic control, benefits often plateau after early adoption, and evidence is limited regarding post-initiation CGM-focused interventions. We conducted a single-arm pilot study among Spanish-speaking adults with T2D who were established CGM users at a federally qualified health center. Participants completed a one-time, culturally tailored CGM-focused educational session delivered in Spanish, with brief post-session follow-up support. Primary outcomes included glycemic control at 3 months. Secondary outcomes included CGM-derived metrics and patient-reported measures of glucose monitoring satisfaction, diabetes distress, and empowerment. Twenty participants (mean CGM use 16.5 months) completed the intervention. HbA1c declined but not significantly (-0.33%, p = .17). Significant improvements were observed in time in range (+11.4%, p = .03) and time in hyperglycemia (-8.7%, p < .001), without increases in hypoglycemia. Participants reported improved glucose monitoring satisfaction and reduced diabetes distress. Empowerment improved immediately post-intervention but was not sustained at 3 months. In conclusion, a culturally informed CGM-focused educational intervention was associated with clinically meaningful improvements in glycemic patterns and psychosocial outcomes among Spanish-speaking Latinx adults with long-standing CGM use, supporting its potential role in enhancing post-initiation CGM engagement and addressing disparities in diabetes.
