  • 1. QALY loss in patients and carers - family impact of meningitis and septicaemia Acknowledgements: (UK) Medical Research Council, Meningitis Research Foundation members, volunteers and staff, Jo Coast, Job Van Exel, Werner Brouwer, Caroline Trotter, Linda Glennie, Shirley Gieron and Laurie Hannigan. Hareth Al-Janabi, University of Birmingham Meningitis Research Foundation Conference, November 2013

  • 5. Economic evaluation using QALYs (quality adjusted life years) Family impact of meningitis: Hareth Al-Janabi Validating the ICECAP-A: Hareth Al-Janabi
  • 6. Measuring QALY changes – Total QALY change comprises:  Impacts on QoL and survival and  ...impacts on patients and anyone else effected – Family QALYs important to capture to minimise bias. – Family QALYs recommended in prominent guidelines: "to calculate the total health effect of an intervention, analysts sum all QALYs" (Gold et al, 1996) “...all direct health effects, whether for patients or, when relevant, carers” (NICE, 2013) Family impact of meningitis: Hareth Al-Janabi Validating the ICECAP-A: Hareth Al-Janabi

  • 10. Research questions  Do the after-effects of meningitis affect family members’ health?  What is the total additional impact on family health? Al-Janabi H, Van Exel J, Brouwer W, Trotter C, Glennie L, Hannigan L, Coast J. Is meningitis associated with adverse health outcomes for survivors’ family network? (under review) Family impact of meningitis: Hareth Al-Janabi Validating the ICECAP-A: Hareth Al-Janabi

  • 12. ‘Family impact of meningitis’ survey  Posted to 3417 members of the MRF: – Likely to be network members of PA – Two questionnaire packs per member – Few exclusions  Questionnaire focused on: – Health of PA – The caring situation (if applicable) – Health of the NM Family impact of meningitis: Hareth Al-Janabi Validating the ICECAP-A: Hareth Al-Janabi

  • 15. Survey response  Total responses: 1600 (for 1226 PA)  Family members mostly (76%) females and mostly (76%) parents – Few (16%) see themselves as carers. – Mean EQ-5D-5L: 0.88  Person affected – 12 years post-infection (average) – Mean EQ-5D-5L: 0.84 – At least one after-effect (67%):  More common: Behaviour – 28%; Mild/mod learning difficulties – 16%; Scarring – 15%  Less common: Incontinence 5%, sight loss 5%, amputation 4% Family impact of meningitis: Hareth Al-Janabi Validating the ICECAP-A: Hareth Al-Janabi

  • 17. Each additional after-effect is bad for the health of the person affected Family impact of meningitis: Hareth Al-Janabi Validating the ICECAP-A: Hareth Al-Janabi
  • 18. ...and bad for the health of family members too Family impact of meningitis: Hareth Al-Janabi Validating the ICECAP-A: Hareth Al-Janabi
  • 19. Providing informal care may harm health  Caring for him is pleasant but often exhausting.  I work full time, so I find caring very tiring and stressful. Family impact of meningitis: Hareth Al-Janabi Validating the ICECAP-A: Hareth Al-Janabi
  • 20. Moods, attitudes and behaviours may change  The impact of the illness on my life was devastating. We all have anxiety and her moods can be very volatile.  [I] mistrust doctors.  It has affected our lives massively. We were a very active couple, running and walking a lot. This no longer happens.

  • 24. Key messages  Meningitis affects family members’ health.  Preventing (and treating) meningitis is likely to generate health gains for family networks.  These impacts should be taken account of in valuefor-money assessments and funding decisions.
