Objective　To investigate the information ability of medical personnel from a large general hospital that integrates medical care

teaching and research under the network environment for providing evidence to improve targeted information service in library. Method　A self-designed and self-administered questionnaire was distributed through the questionnaire system on hospital office net-work. Information ability involved in the questionnaire mainly included the ability to precisely retrieve literature in Chinese and foreign language

commonly used retrieval strategies

and screening

evalua-tion and English full-text access methods. A total of 1 094 medical personnel voluntarily participated and completed the questionnaire

and complete responses were obtained from 1 065 individuals (effec-tive response rate 97.35%). χ2 and trend χ2 tests were used for data analysis. Results　The overall accuracy of precise retrieval information was only 6.1%

and the accuracies of precise retrieval literature in Chinese and foreign language databases were 14.6% and 14.6%

respectively. Duty

education and working years of the medical personnel had significantly effects on the ability to precisely retrieve literature and the strategies and methods of information retrieval

screening

evaluation and full-text access. Conclusion　Medical personnel had certain information ability

but library should carry out relevant training program to improve the medical personnel’s information quality and ability further.
