Abstract
"Objective: To systematically review the research issues related to evidence quality grading methods for public health decision making, and to provide a reference basis for the selection of key issues for evidence quality grading in public health decision making.
Methods: A computer search of PubMed, EMbase, Web of Science, CNKI, WanFang Data, CBM and VIP databases was conducted to collect studies related to the application of evidence quality grading methods for public health decision making, with the search period from the establishment of the database to December 2022. The questions were constructed according to the SPIDER model and the inclusion and exclusion criteria were formulated. The quality of the included literature was evaluated by using the CASP checklist, and a three-level interpretation analysis of the questions on the application of quality rating methods for public health decision making was conducted using the thematic synthesis method to establish a pool of question entries.
Results: A total of 14 papers were included, covering seven countries. GRADE was the commonly used method for grading the quality of evidence. CASP evaluation results showed eight high quality studies, four medium quality studies and two low quality studies. The thematic synthesis method summarised 13 question entries in 7 categories.
Conclusion: The existing methodology for grading the quality of evidence for public health policymaking suffers from the diversity of evidence sources and the underestimation of the level of evidence from complex intervention studies. Therefore, there is a need to collate the key questions for the method of grading the quality of evidence for public health decision making, so as to provide a reference basis for the optimization and development of the method of grading the quality of evidence for public health decision making.
