Abstract: Objective To understand the situation to the family doctors' knowledge of chronic kidney disease (CKD) in the outer suburbs of Shanghai, and to provide basis for carrying out the CKD training in family doctor system and promoting the service ability of community team. Methods A questionnaire survey through the mobile WeChat was used to investigate 694 medical staff in family doctor team from ten community health service centers in Qingpu District. The survey included the basic situation of the research objects and the questions about CKD, 694 valid questionnaires were finished with the effective rate of 100%. The quantitative data were shown as x±s, and t-test and ANOVA were used among the two groups, and the quantitative data were expressed as percentage or rate(%) in a descriptive statistical way. Results The average score of CKD knowledge among the 694 objects was 52.31±15.83, with a pass rate of 32.71%. As a result, the CKD scores didn't show any significant difference (P>0.05) in members with different gender and different working years. Among others with different age, occupation and titles, however, the CKD scores were significantly different (P<0.01). Interestingly, the scores were lower in staff less than 30 years old, and the scores of GP were significantly higher compared with other types of medical staff, and the scores from intermediate title and above were also higher than junior titles. Conclusion The CKD knowledge is very poor and need to be further improved in community family team. We should improve the propaganda of CKD basic knowledge, and move forward the disease prevention and control, and decrease the disease harm to human health, and also cut down the medical cost in CKD patients at the same time.
