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)

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’ 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

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%):
