The COVID-19 pandemic has exposed the fragmentation of the healthcare delivery systems and highlighted the role of resilient primary healthcare systems for a robust public health response during health emergencies. Primary care while being the first point of contact between the citizens and the health systems has received scant attention or targeted investments over the past several decades. Through this narrative review, we aim to outline the potential role of telehealth in augmenting health systems capacity. While teleconsultations have increased exponentially during the pandemic, evidence suggests that utilisation of primary care for non-emergency and non-COVID-19 conditions such as chronic medical conditions has significantly decreased, suggesting that most telemedicine utilisation has been to address an immediate crisis. In countries with pre-existing national digital health framework and enabling regulatory environments, telehealth interventions while strengthening the public health response to COVID-19 also supported the continuum of care at the primary care level. Even after COVID-19 is controlled, telemedicine has the potential to address persistent obstacles to primary care in the South East Asia region, including scarcity of trained healthcare workers, access challenges and costs associated with in-person care. Telemedicine holds promise in strengthening primary care and has the potential to catalyse achieving universal health coverage. © Author(s) (or their employer(s)) 2021. No commercial re-use.
