public-private partnership: an effective solution for providing health services to the elderly

population aging has become a significant phenomenon in the 21st century due to rising life expectancy and declining fertility rates. the global elderly population, estimated at 727 million in 2020, is projected to double by 2050, with developing countries facing a greater proportion of elderly residents. this demographic shift will impact various sectors of society, including healthcare, leading to increased demand for medical services and higher costs. public-private partnerships (ppp) are an effective mechanism to improve access to health services for the elderly, enhance service quality, and manage costs. it is crucial for policymakers to explore global experiences with ppp to develop strategies that address the unique economic and social conditions in iran, ensuring an effective response to the rapid changes in healthcare needs for the aging population.
