PHC is the first level of care at which most patients access the health system. In addition to these treatment guidelines aimed at healthcare workers at PHC facilities, the Essential Medicines List Clinical Guide mobile application encourages improved access to Standard Treatment Guidelines at all levels of care. Healthcare services can then be accessed at primary level of care dependant on the level of skills and resources available at each individual facility. The STGs and EML provide clear guidance to support equitable access to essential health care services at the primary level of care to enable the prevention and treatment of a wide range of acute and chronic conditions, with appropriate referral to higher levels of care.
