World Health Survey - WHS Basic Messages
WHO’s World Health Survey WHS programme announced by DG
Complements the data for Health Information Systems
Responds to the need for cross-culturally comparable data
Surveys are useful, practical and affordable
WHS instruments
Modular structure for health, responsiveness, financing ...
Health module based on selected domains of ICF
Based on review of various existing assessment instruments
Developed through:
Cognitive interviews & cultural applicability tests
Reliability - stability of application
Cross-population comparability - HOPIT
WHO in collaboration with Member States is committed:
Capacity building & sharing experience
Integration of WHS surveys into routine Health Information Systems

3. The World Health Survey Objectives
04/06/2018
The World Health Survey Objectives
develop a means of providing:
valid, relevant, reliable and comparable information
at low cost
on outcomes, functions and inputs to health systems
to supplement the information provided by routine HIS
build the evidence base necessary for policy-makers:
to routinely monitor if health systems are achieving the desired goals
and in some countries, to assess if the increase in health resources is having the desired effect
.Develop valid, reliable and comparable instruments to describe individual health states and responsiveness on a core set of domains and to field these in household surveys.
.Test the validity of multiple modes of survey implementation including long-form household, short-form household, self- administered and computer-assisted telephone interview.
Develop WHO and Member States capacity to field surveys with quality control, appropriate sampling, and data management strategies as well as to build capacity to analyse data from complex surveys.
