The difficulty in diagnosis rate of HAP/VAP pathogens in China are largely different and treatment of HAP/VAP leads to high mortality. In from the data reported in other countries. Therefore, it is China, it has been nearly two decades since the initial necessary to amend the initial guideline in 1999 accordingly “Guideline for the Diagnosis and Treatment of Hospital-acquired in order to better guide clinical practice. Pneumonia (draft)” was published in 1999 (1). Afterwards, The initial HAP guideline was updated by the Infection a number of guidelines for HAP/VAP have been published Study Group of Chinese Thoracic Society, Chinese Medical or updated at home and abroad (2-10). The definitions of Association (CMA). The overall framework and main HAP/VAP have been changing as more and more relevant contents of the updated HAP/VAP guideline were finalized researches available highlighting greater details. Moreover, after multiple rounds of face-to-face workshops. After there are growing evidence in the epidemiology, etiology, repeated discussions among all the members of the Infection clinical diagnosis and treatment of HAP/VAP, especially Study Group and extensive consultations from domestic and © Journal of Thoracic Disease.

Decisions should be made with consideration of the specific condition of the patient to reflect his/her values and willingness C (weak) Insufficient evidence; decisions must be made via mutual discussions involving the patients, physicians, and policy makers foreign experts in related fields, the draft was revised several of hospital admission and occurring 48 hours or more after times. Finally, the consensus was reached on the basis of admission in patients not receiving invasive mechanical evidence-based medicine. The level of evidence and grading ventilation during hospitalization. VAP is defined as a of recommendation are defined the same way as in “Diagnosis pneumonia occurring >48 hours after endotracheal intubation and treatment of community-acquired pneumonia in adults: or tracheotomy to receive mechanical ventilation. A 2016 clinical practice guidelines by the Chinese Thoracic Society, pneumonia occurring within 48 h after removing mechanical Chinese Medical Association (2016 Edition)” (11). The grading ventilation and extubation is also considered as VAP (2,3). system classifies recommendations according to the balance At early times, HAP was defined as any parenchymal of the benefits and downsides (harms, burden, and cost) on lung infection occurring in hospital due to the pathogens the basis of the quality of evidence. The quality of evidence existing in the hospital environment. In the Chinese reflects the confidence in estimates of the true effects of “Guideline for the Diagnosis and Treatment of Hospital-acquired an intervention (Table 1). In general, the higher the quality Pneumonia (draft)” published in 1999, the definition of of evidence is, the stronger the grade of recommendation. HAP covered the pneumonia occurring after establishing However, they do not fully correspond to each other. The artificial airway and mechanical ventilation (1). There source of evidence, willingness and values of patients, as are various confounding factors in the numerous HAP well as resource consumption should also be considered clinical studies previously conducted at home and abroad, when making a recommendation. We emphasize that under including some patients undergoing mechanical ventilation. the premise of the same level of evidence, the evidence and However, it is generally agreed that VAP is a special type research results in China should be adopted preferentially. of HAP. Considering the significant difference between This guideline applies to the immunocompetent HAP/ HAP and VAP in terms of clinical features, empiric VAP patients aged 18 years or older. The main body of treatment, and prevention strategy, the Guidelines for this document is composed of 8 sections and 1 annex. It the management of adults with hospital-acquired, ventilator- is expected that the revision and popularization of this associated, and healthcare-associated pneumonia issued by the HAP/VAP guideline will further standardize the diagnosis and Infectious Diseases Society of America/American Thoracic treatment of HAP/VAP in China. Society (IDSA/ATS) in 2005 (2005 IDSA/ATS HAP/VAP guideline) have classified HAP into HAP in narrow sense and VAP (2). The evidence in recent years further confirms Definitions that HAP is considerably different from VAP in empiric HAP is defined as a pneumonia not incubating at the time treatment and clinical prognosis.

The all-cause HAP only refers to the pneumonia occurring after hospital mortality of HAP is 22.3% and 34.5% for VAP. HAP is admission in the patients without endotracheal intubation associated with 23.8±20.5 days of hospital stay on average, and not associated with mechanical ventilation, while VAP 10 days longer than that of non-HAP patients.
