22 U.S.-bound Refugees: Medical Evaluation Panel physicians (DoS) Required overseas medical examination ~2-6 mos State health dept ~1-3 mos Recommended domestic examination in US (DIFFERENT from overseas exam)

23 Current status of medical evaluation for U.S. bound refugees Overseas Pre-departure responses Medical Assessment Required for all refugees (and immigrants) Must be performed by designated Panel Physician Technical Instructions for medical exam published by CDC. Pre-departure presumptive treatment Increasing vaccination Post-arrival medical screening and evaluation New guidelines under development beginning in Post-arrival responses

43 BEFORE paper paper If no CDC presence at port of entry, CBP couriers to assigned CDC Quarantine EDN Medical forms are complete Immigrant arrives with paper forms CBP manually identifies and pulls record, reviews and transfers to CDC Add 1-7 Days CDC quarantine couriers paper forms to CDC HQ Forms manually entered into EDN, record is available to health department 1-6 months prior to arrival Day 1: Arrival Day 1 CBP misses some, which never get to CDC Day 2-5 (or 3-12) Day 5-7 (or 7-14) AFTER emedical & Pre-EDN database Medical forms are complete Immigrant arrives Pre-EDN Database CBP records arrival, record automatically transferred EDN Record is crossed referenced, automatically loaded into EDN and available to health departments 1-6 months prior to arrival Day 1: Arrival Day 1 Day 2

44 Domestic medical screening and evaluation

45 Areas being addressed in current guidelines Preventive Health Interventions History and physical examination Routine immunizations TB testing Counseling & Mental Health Nutrition Growth and Development Female Genital excision Mental Health Screening

46 Areas being addressed in current guidelines Laboratory Testing & Disease Specific Sections Overseas & domestic malaria Overseas & domestic Intestinal Parasites Hepatitis A-E General HIV Lead STI/syphilis Vitamin D

47 Future directions and Challenges Increase post-arrival surveillance Increase in population specific guidelines Flexibility--from reactive to pro-active. Shift from domestic to more predeparture screening and treatment Increased communication across systems (e.g. from overseas to postarrival clinicians). Begin to work with non-refugee immigrant populations.

48 Initiatives Increased pre-departure interventions Centers of Excellence Dissemination of best practices Guideline development/improvement Increased surveillance Improved medical education Train persons from communities to serve communities

49 Centers of Excellence in Refugee Health ( ) q Surveillance/epidemiology of refugee populations Building a data repository for refugee health data from post-arrival screens Conducting clinical quality improvement evaluations on Hep B, LTBI, and chronic conditions in pediatric patients q Guideline Development and Revisions New Guidelines: Preventative Medicine, Women s Health, Pediatrics Revisions to Current CDC Guidelines: Mental Health, General, Hepatitis, Parasitics

50 Strengthening Surveillance for Diseases Among Newly-Arrived Immigrants and Refugees ( ) Enhancing state or local refugee health surveillance systems by Automating processes Linking to other surveillance systems within a state Providing large dataset to describe refugee populations

51 Mobility: time for health interventions? Refugee Camps Urban Centers Prevention, surveillance & Intervention opportunities Overseas Medical Exam Sites Quarantine Stations Resettlement Communities

54 Where do the real public health threats come from?

55 With 1 billion people crossing international borders each year, there is no where in the world from which we are remote and no one from whom we are disconnected.
