  10. CDC Grant Objectives (1) • 90% of VPD investigations are sent to CDC within 30 days of receiving report • Texas reality: <80% within 30 days • Why timeliness is important • Many interventions have time restrictions • Detect state-wide or national trends/outbreaks • Improvement Plan • Provide semi-annual feedback to locals/regions on timeliness • Improve turn around time at Central Office

  11. CDC Grant Objectives (2) • Known vaccination status for at least 90% of cases • Texas reality • 100% HIB <5 years • 36% meningococcal • 75% in <18 age group • 70% mumps • 93% in <18 age group • 79% pertussis • 92% in <18 age group

  12. CDC Grant Objectives (2) • Capturing vaccination status is important to assess control measures, vaccine efficacy/schedule, vaccination policies, etc • Giving feedback to local and regional health departments on semi-annual basis • Include reminders about all possible ways to capture vaccine information • Exploring ways to streamline data capture (can Immtrac talk to our database?)
