Abstract： The "three preventions" concept of Chinese medicine in preventive treatment—preventing disease before it occurs， preventing deterioration once it occurs， and preventing relapse after recovery—has demonstrated remarkable effects in disease prevention and prognosis regulation. As frontline medical units directly serving the broad masses of the people， the significance and necessity of establishing preventive treatment centers in communities are self-evident. This study first reviews the obstacles currently faced by these centers in terms of internal construction. It then introduces and applies the operational mechanism of the Body-Qi-Spirit diagnosis and treatment model， which encompasses "one concept， two ways of thinking， three pathways， and four steps." Finally， it concludes that this model can provide standardized service processes for current preventive treatment centers in communities，improve their operational mechanisms， integrate their internal medical resources， cultivate professional backbone staff， enhance their benefits，and reflect the value of medical personnel engaged in preventive treatment.
