Tools overview and purpose

	Stated aim(s) of tool	Approach and theoretical foundations	Adaptability to extend (eg, custom interventions)
CAPACITI	Support evaluation of immunisation options incorporating values and programme context	MCDA embedded in broader problem-structuring framework	Focus on immunisation programmes but can extend to other
PriorityVax	Support vaccine prioritisation; clarify data uncertainty impact; facilitate discussion; clarify stakeholder views	MCDA embedded in broader problem-structuring framework	Focus on immunisation programmes but can extend to toher
HIPtool	Support health intervention prioritisation at country level	Evidence-synthesis	Yes
Optima	Analyse and project HIV and TB epidemics; determine optimal resource allocations	Impact model: dynamic compartmental models; Costing: logistic cost function model; Global optimisation to minimise outcome (eg, DALYs) or costs to achieve defined outcomes	No
OneHealth (spectrum suite)	Support to inform national healthcare planning and resource needs at country level, strengthening health system analysis, costing and finance	Impact model: module specific (eg, LiST for child and maternal health interventions, or TIME, a dynamic compartmental model for TB); Costing: ingredients-based costing	Custom interventions can be added
LiST	Estimate the impact of scaling up MNCH&N interventions in LMICs	Impact model: static equation-based model; costing: ingredient-based costing	Focus on MNCH&N; Custom interventions can be added; only LMICs
EQUIST	Estimate the impact of scaling up MNCH&N interventions in LMICs	Bottleneck analysis and statistical analysis of changes to effective coverage; Impact analysis: based on LiST; costing: based on LiST and OneHealth	Focus on MNCH&N; only LMICs

*Adaptability to extend to new diseases and interventions.
