| 目的：探讨光电阅读机在大样本现场调查项目质量控制和数据录入中的作用。方法：使用光电阅读机读入《子宫颈癌危险因
素调查表》信息并进行表格质量评估，核查调查表中调查对象编码缺失、重复及进行读入信息一致性比对。结果：在录入的70160
份数据中，调查对象编码缺失率为0.87%，调查对象编码重复率为0.79%，信息一致率为99.47%。3 个项目点连续三个月质量控
制，表格不合格率略有下降。结论：在大人群现场调查项目中通过光电阅读机进行质量控制及数据录入，能快速准确的将纸质信
息转化为电子信息，并对电子信息进行核查，能迅速将调查表评估结果和建议反馈给调查表填写人员，及时指导调查员改进调查
项目的编写方法和调查表内容的填写方法，从而提高了调查表信息采集质量，促进项目科研数据真实可信。 |

| Objective: To approach the role of the Optical Mark Reader (OMR) in quality control of site interviewing and data
entry in a large sample project of field work. Methods: The OMR was used to data entry of the questionnaires of risk factors for cervical
cancer, several indexes were checked such as the code missing, the code repetition and the consistency of data information. Results：In
the total number of 70160 data entry, the rate of code missing was 0.87%, the code repetition rate was 0.79% , and the information
consistency was 99.47%. The percent of disqualified questionnaires was declined after quality control for three months. Conclusion：It
was fast and accurate to transform paper-based to electronic information by using OMR for data entry in large sample project. After
verifying electronic information according to the paper-based information, the results and feedback suggestions were given to the site
interviewers, to guide the interviewers to improve the compilation of survey items and the questionnaire content. These improved the
quality of survey information and promoted the research data authentic. |
