Objective To determine the causes and risk factors of antimicrobial treatment failure in patients with community-acquired pneumonia(CAP). Methods Hospitalized adults with CAP from January 2006 to December 2006 were analyzed retrospectively. Treatment failure was defined as appearance of nonresponding pneumonia and progressive pneumonia. Patient's clinical features were analyzed. Results All of 378 patients were involved in this study. Total antimicrobial treatment failure was happened in 50 patients(32 patients with non-responding pneumonia and 18 patients with progressive pneumonia). The causes were infectious (35 patients,70% ), non-infectious (11 patients,22% ) and undetermined (4 patients,8% ).Mortality of antimicrobial treatment failure was 18%(9/50, 8 patients died of infectious cause, 1 patient had no clear cause of death). Stepwise Logistic regression analysis showed that C-reactive protein, multilobar pneumonia,albumin < 30 g/L,renal function lesion,liver function lesion were related with antimicrobial treatment failure. Independent factors of treatment failure were multilobar pneumonia (P= 0.002) ,albumin <30 g/L(P = 0.001 ) and renal function lesion (P = 0.000). Conclusion The major challenge associated with antimicrobial treatment failure in hospitalized patients with CAP is infection, most of which is infection of drug resistant strain.

Objective:To analyze the changes in the number and workload of pediatricians, for evidences in further optimizing the allocation of pediatrician resources and formulating relevant policies in China.Methods:According to data from the National Bureau of Statistics and the " China Health and Health Statistics Yearbook", descriptive analysis was made to investigate the changes in the number and workload of pediatricians in China from 2010 to 2019.Results:During 2010 and 2019, the number of pediatric practitioners(assistants) increased from 115 800 to 158 500, and the growth rate was faster than that of the children aged 0-14 years, but slower than that of overall medical practitioners(assistants). The number of pediatric practitioners(assistants) per thousand children in China had grown steadily from 0.52 to 0.67, compared with the burden and the workload of medical practitioners nationwide, the workload of pediatricians was still relatively heavy.Conclusions:The number of pediatricians had increased gradually between 2010 and 2019, and the effects of various policies began to work, while the workload was still heavy. It is recommended to further develop a salary system and supporting policies in line with the characteristics of pediatrics sector, and focus on such problems as unbalanced and inadequate distribution of pediatricians.
