Poorly functioning health systems are a central challenge to realizing the benefits of UHC. Health systems in LMICs commonly suffer from a variety of weaknesses, including absenteeism and insufficienttraining among health care workers, mistreatment of patients by health care workers, corruption, poorly functioning inventory systems and supply chains, electricity cuts and outages, and lack of clean water. These shortcomings in health care delivery often reflect higher-level problems in governance and market failures. Achieving UHC will therefore require innovations in the structure and operation of health systems to ensure that rapid expansion in coverage is not undermined by shortcomings in delivery and quality of careThis is the statement I have picked up as a key message in an excellent article about universal health care (UHC) in Science. The issue goes beyond appropriate financing, and unless countries take decisions for better organization and governance, more promises (on financing) may get more perils (unexpected outcomes).
PS. By the way, the paper is written by US scholars, that forget that US doesn't have UHC! They only talk about low and middle income countries.
PS. Check the latest change of universal health care in Spain, the weirdest health financing system of the world, neither social security, nor national health system, both at the same time (!)
