‘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 findings summary
 Family members of people with after-effects have:
– Worse overall health
– Higher levels of depression/anxiety.
 Additional after-effects erode the health of both people affected
and family members.
 Certain after-effects are particularly bad for family members’
health (learning disability, behavioural problems, pain, seizures
and hypotonia).
 Partners’ health is affected more than parents’ health.

Caring can be physically and emotionally
draining
 Caring for him is pleasant but often exhausting.
 I work full time, so I find caring very tiring and
stressful.
 It changed my life. I worry so much that my daughter
could get it again. I get very anxious when she gets ill.
Validating the ICECAP-A: Hareth Al-JanabiHealth externalities: Hareth Al-Janabi
Having a loved one in poor health can affect
moods, attitudes and behaviour
 Carefree life ...no longer available ...worry, stress,
anxiety and isolation.
 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.

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

Editor's Notes

  • #4 READ Happy for interruptions and questions
  • #5 READ Happy for interruptions and questions
  • #9 1. As a precusor to econ eval work in this area – we examined HEX from meningitis 2. contagious and deadly illness – strikes children/babies – often described as parents biggest fear. Vaccines for some strains. Mortality rate. Many survivors live with psych/phys problems eg… Impact of these on family/network. 3. Why this area. Honest - chance. Case study- interesting from a scientific POV: parents, range of after-effects 4. From a policy perspective – Bexsero vaccination for main remaining cause of men – meningo Gp B just been approved by the EM agency and Uk and other countries due to make funding decision this year.
  • #12 1) Following focus group & formal pilot.....READ....In May 2012 iii) Key reasons – PA, not close to someone with men, bereaved...excluded if possible before posting, but if not after not excluded at this stage if person had made a full recovery – nice control group 2) i)READ inc detailed Q on after-effects ii) time, role, experiences iii) Often parent, could be spouse, sibling, grandparent any self-defining person close to PA…+ various measures, socio-demographic, contextual data
  • #16 DESCRITPIVE STUFF Top – 3417 packs mailed out
  • #17 ...following two reminders, we heard back from 37% of the households (most of whom eligible) ... 69% sent back one questionnaire and 31% generated two (not necessarily from same household) Total of 1600 NM – PA dyads.
  • #18 Characteristics… … for PA mostly children and young adults (although a couple in 80s) … mostly pretty good health .., average of 12 years since infection … For NM mostly female, somewhat older, and in better health state (but not much!) … context mostly child-parent dyads (although smaller numbers of lots of other relats), mostly living together (but substantial minority not), only 1/6 NMs described themselves as carers
  • #20 … but what about confounding? Tried to control for possible external influences (i) S-D, e.g. age/sex/educ that may influence both (ii) time since diag (iii) common genes (iv) common environment We also allowed for (i) clustering – i.e. two response for PA health (ii) explored functional forms for IVs and investigated potential MS of reg mod (iii) carried out a number of robustness/validity checks – go into a bit more detail if interested.

  • #23 READ Happy for interruptions and questions
  • #24 Applied messages for CEA/hpolicy in Men – bad for MH, 17%, …depending on assumption about additional Method messages about HEX for econ eval in general – carers/non-carers, beyond closest, decay
  • #25 Just to finish – acknowledge the contributions of the orgs and people who have also played a big part in this research
