Recent data indicate that about 96% of Colombians are now covered by health insurance arrangements. Progress in formal coverage has been accompanied by remarkable improvements over the last 20 years in access to services by disadvantaged populations and increased health sector funding, while reducing the participation of out-of-pocket payments as a source of health care financing, with likely positive implications for overall levels of financial protection. Some of these challenges are common to countries at similar stages of economic development as Colombia, including a rapidly ageing population and declining workforce.
