Which of the following is one of the main roles of secondary care?

Secondary care primarily involves specialized medical services that patients receive after referral from a primary care provider. One of its main roles is conducting surgical procedures, which require advanced medical training and specialized facilities. This level of care addresses specific health issues requiring expertise and technology not typically available in primary care settings.

In contrast, preventive measures, routine health check-ups, and long-term patient care are generally associated with primary care or tertiary care. Preventive measures focus on avoiding diseases, while routine health check-ups emphasize regular monitoring of health status to catch any potential problems early. Long-term patient care usually involves ongoing management of chronic conditions and is often associated with both primary and palliative care settings. Each of these functions is essential in the healthcare continuum but differ in scope and specialization, emphasizing the unique position of secondary care in providing more sophisticated medical interventions such as surgical procedures.
