What are the 4 levels of patient care?
Healthcare delivery systems typically categorize medical treatment into four distinct tiers based on clinical complexity and acuity. The first tier is primary care, encompassing routine health maintenance, preventative screenings, and general wellness managed by family physicians. The second tier is secondary care, involving specialized medical services provided by physicians like cardiologists or dermatologists upon patient referral. The third tier is tertiary care, representing advanced diagnostic and surgical procedures performed in specialized medical centers for complex conditions. The fourth tier is quaternary care, serving as an even more specialized extension of tertiary care for rare experimental treatments, advanced clinical trials, and highly complex surgical interventions.
