The rapid technological and medical advancements of the 21st century, particularly the widespread administration of combination antiretroviral therapy (ART), have fundamentally transformed the global trajectory of the HIV/AIDS epidemic. What was once universally considered a rapidly fatal infectious disease has transitioned into a manageable chronic condition. Consequently, the life expectancy of persons living with HIV (PLWH) has increased dramatically, shifting the demographic landscape toward a rapidly aging population. The primary aim of this extensive literature study is to critically analyze the multidimensional complexity of aging with HIV and to establish a robust, expansive conceptual framework for integrating geriatric principles into the existing healthcare system. Utilizing a qualitative literature study and content analysis approach, this paper synthesizes the profound clinical, psychological, and systemic challenges faced by Older People Living with HIV (OPLH). The analysis evaluates these intertwined challenges under the global mandates of the 2030 Sustainable Development Goals (SDGs) and the UNAIDS 95-95-95 targets. By rigorously applying the Health Policy Triangle (evaluating Context, Content, Process, and Actors), this paper provides a detailed, actionable implementation pathway for a national healthcare provider training program centered entirely on the Geriatric 5Ms framework (What Matters Most, The Mind, Mobility, Medications, Multi-complexity). The findings unequivocally assert that integrating this framework into routine HIV care is not only highly feasible but absolutely critical for delivering sustainable, evidence-based, and non-discriminatory care at the grassroots and community levels, ultimately preventing unnecessary complications and reducing systemic healthcare burdens.
