How do we improve the links between
Primary Care and Public Health/Prevention
• Pay for Prevention Services
• Add Physician Extenders to Practice
– NP, PA, H.Ed., MH Counsellor
• Use of Computerized Records that
– Remind need of Immunizations
– Remind Need for Routine Management
– Provide Health Ed. Material
– Computer links to patieints.
PC – PH Prevention Links
• Closer Health Department – Practicing
physician ties.
– Weekly or monthly surveillance reports
– Databases of Community Health Status
– Prevention talks at Hospital meetings
– Epidemiologic Surveys of patient records
• CAS
– Periodic review of death records with Rx for
prevention activities
