The provision of primary healthcare services in developing countries remains a significant challenge, particularly in low and middle-income countries. According to the World Health Organization (WHO), scaling up primary healthcare interventions across these countries could save 60 million lives and increase average life expectancy by 3.7 years by 2030. The concept of primary healthcare developed during the 1970s as part of the basic needs of social development. WHO and UNICEF elaborated the strategy of primary health care as the means to achieve Health for ALL.
