預防醫學分為三級：初級預防（Primary Prevention）旨在預防疾病發生；次級預防（Secondary Prevention）針對早期發現與篩檢；三級預防（Tertiary Prevention）則是針對已確診的疾病，重點在於限制疾病惡化、預防併發症並促進復健。糖尿病足部照護屬於三級預防，因為其目的是避免因周邊神經病變或循環障礙導致的潰瘍、感染與截肢。
Preventive medicine is divided into three levels: primary prevention aims to prevent the onset of disease; secondary prevention focuses on early detection and screening; tertiary prevention is directed at clients with an established diagnosis and emphasizes limiting disease progression, preventing complications, and promoting rehabilitation. Diabetic foot care is considered tertiary prevention because its purpose is to avoid ulcers, infection, and amputation caused by peripheral neuropathy or impaired circulation.
