Health statistics: time to get serious.

Health statistics, including both empirical data and estimates related to health such as mortality, morbidity, risk factors, health service coverage, and health systems, are the basis for every aspect of health planning. The demand for better health statistics is rapidly growing. More money is being spent on global health than ever, and donors are keen to know their return on investment. In the financial sector, credibility and accountability are everything. Why not in the health sector? Tracking progress towards the Millennium Development Goals and performance-based funding, are promoting greater demand. We cannot afford to continue “stumbling around in the dark” any longer (1). The supply side is not sitting still either. The Health Metrics Network, launched in May 2005, is a new international partnership that aims to improve health information at all levels primarily by strengthening health information systems in countries.

There is now a great opportunity to improve both the quality and quantity of health statistics. The next key step for WHO is to better define its role among the rapidly proliferating health statistics constituency. First and foremost, WHO’s comparative advantage must be reconsidered. The Organization’s work in health statistics needs to build upon its constitutional and legitimate links with Member States and its convening power to reach consensus and facilitate harmonization at the country and regional levels with lead partners in the health field. The flip side of this comparative advantage is the intense political pressure to which WHO figures are subject and the often poor quality of countrylevel data provided by its Member States upon which estimates are based. Recently, the appropriateness of WHO as a global health monitoring body has been questioned due to its multiple roles in advocacy, technical assistance to
