  1. Module 4:Evaluate Health Impacts • HHRS Module 4 developed by • Erica Forrest, Supervisor, Training and Education • Center for Environmental Health • Division of Allergy/Asthma/Immunology • Children’s Mercy Hospitals and Clinics

  2. Page 4.1 Learning objectives

  3. Page 4.1 The HHRS Process

  4. Page 4.2 Review of Key Principles

  5. Page 4.2 Categories of hazards

  6. Page 4.3 Categories of Hazards

  7. Page 4.3 The HHRS Formula

  8. Page 4.3 Two Judgments by Assessor

  9. Page 4.4 First Judgment: Likelihood

  10. Page 4.4 Judging Likelihood

  11. Page 4.5 Judging Likelihood

  12. Page 4.5 Likelihood Numbers • Hazard Profiles give national UK average likelihoods for vulnerable age group. • Only assess hazards that presently cause, or are likely to cause harm, over next 12 months. • The UK likelihoods are only a reference.

  13. Page 4.5 Likelihood for Mold & Moisture

  14. Page 4.6 Determining Likelihoods

  15. Page 4.7 Second Judgment: Outcomes

  16. Page 4.7 Second Judgment: Outcomes

  17. Page 4.8 Classes of Harm (Harm Outcomes)

  18. Page 4.8 Classes of Harm (Harm Outcomes)

  19. Page 4.8 Assessing the Outcomes • When assessing spread of harm, consider: • Average spread of harm outcomes for the particular type/age of dwelling • Dwelling characteristics and conditions identified may increase or decrease the severity of those outcomes

  20. Page 4.8 Outcomes for Excess Heat

  21. Page 4.9 Outcomes for Excess Heat • When scoring, you are considering how the deficiencies contribute to harm in each Class. • Unless the conditions call for adjusting the outcomes, they should be accepted as-is. • The sum of the classes will total 100%. 31.6 10 36.9 21.5

  22. Page 4.10 The Numerical Score • The hazard score is determined by adding up the individual scores from each class of harm using the standard formula. • The likelihood remains constant but the weight of each class alters the score for that class.

  23. Page 4.10 The Result – Hazard Bands

  24. Page 4.11 Band Hazard Score Range

  25. Page 4.11 Practice: Determining likelihoods, outcomes, hazard scores and bands

  26. Page 4.11 Scoring a Hazard: the Complete Process

  27. Page 4.12 Falling on level surfaces

  28. Page 4.12 Mold and Moisture

  29. Page 4.12 Falling on stairs and falling between levels

  30. Page 4.13 Exercise

  31. Page 4.14 Review • Describe the purpose of using the HHRS rating system to rate hazards • Explain how to determine the likelihood and spread of harm outcomes of a hazard • Use the HHRS formula to determine the hazard score • Evaluate the severity of the hazard score to prioritize appropriate interventions

  32. Train-the-trainer teachback • Take 5 minutes to review the assessment your trainer sent you. • Using slides 13, 20, 21 – 24, put yourself in the role of the teacher and teach this class how to score your assessment. • Each student will have 5 – 7 minutes to do this. • We will give you control of the slides. • Please open up the Excel scoring tool to show students how you do the calculation.
