Objectives As part of the National Institute for Health and Clinical Excellence (NICE) Single Technology Appraisal (STA) process, manufacturers present submissions outlining the clinical and cost-effectiveness of new technologies. These submissions are critically appraised by Evidence Review Groups (ERGs), who produce a report, which forms part of the evidence considered by the NICE Appraisal Committees. The purpose of this research was first to identify common issues and concerns identified by the ERGs in their analyses of manufacturers' submissions (MS). The aim was then to use these as a basis to develop feedback for manufacturers.
Design A qualitative study using a content analysis approach to examine two sources of evidence, the first 30 ERG reports and 21 clarification letters associated with these STAs.
Setting UK HTA programme.
Primary and secondary outcome measures Common issues and concerns in MS.
Results There were positive comments regarding the quality of the MS, many of which were clearly written. The majority, however, were generally of poor quality and issues and concerns identified across the ERG reports and clarification letters included: criticisms related to the data being used especially data employed in the cost-effectiveness model, failure to perform a necessary analysis and poor reporting of processes used in the MS. Aspects of the decision problem were also often poorly or inadequately addressed by manufacturers. The majority of points raised for clarification related to the economic data analysis. Internal inconsistencies between the clinical and economic sections of the submission were frequently highlighted. These were used as the basis for the development of 12 suggestions for manufacturers.
Conclusions Much can be done to improve the quality of MS in the NICE STA process. Suggestions include the need for clear and transparent reporting of methods and analyses.
