Authors' objectives:

- To describe systematically studies that directly assessed the learning curve effect of health technologies. - Systematically to identify novel statistical techniques applied to learning curve data in other fields, such as psychology and manufacturing. - To test these statistical techniques in data sets from studies of varying designs to assess health technologies in which learning curve effects are known to exist.

Authors' recommendations: Health technology assessment literature review The statistical methods used for assessing learning effects in health technology assessment have been crude and the reporting of studies poor. Non-health technology assessment literature search A number of statistical methods for assessing learning effects were identified that had not hitherto been used in health technology assessment. There was a hierarchy of methods for the identification and measurement of learning, and the more sophisticated methods for both have had little if any use in health technology assessment. This demonstrated the value of considering fields outside clinical research when addressing methodological issues in health technology assessment. Testing of statistical methods It has been demonstrated that the portfolio of techniques identified can enhance investigations of learning curve effects.
