Improvements in health coverage as measured by access to services is demonstrated in some key metrics, such as reductions in unmet health care needs, reductions in waiting times for an appointment, and increased perceptions of quality by service users (Figures 1.12, 2.2 and 1.13 respectively). As with extension of financial protection, improved access to services has mostly benefited the poorest Colombians: reported unmet health care needs in the past month fell from 33.2% surveyed in 1993 to 2.0% in 2013 (compared to 7.3% and 0.9% respectively amongst the richest quintile) and preventive health care consultations (in the 12 months prior to being surveyed) rose from 30.1% of the population surveyed in 1993 to 62.8% in 2010 (compared to 50.2% and 78.9% respectively amongst the richest quintile). The vast majority of these health system contacts (85%) were in the ambulatory care sector (MSPS, 2013a). Reassuringly, only 15% of health system contacts involved complex emergency care and/or hospital admissions, which suggests that the system as a whole is not adversely biased tow'ard hospital care.
