A nurse is revising а prоgrаm gоаl that оriginally read: "Reduce ED visits for pediatric asthma exacerbations." The team proposes: "Reduce pediatric asthma-related ED visits in the county by 40% within 8 months, driven primarily by a home visiting nurse program targeting 50 high-risk families." Baseline data show similar interventions elsewhere have achieved a 15-20% reduction over 12-18 months. Which SMART element is now most compromised by this revision, even though the goal appears more specific and measurable than the original?
