We explore this via two studies (from which we confirm the central role of logbooks) and propose three modes of mediation: facilitating cognition and creation, gathering and collation of information, and staging and transformation of information.
Furthermore, most population-based studies use administrative data from registries and therefore miss detailed clinical information and stage-specific analysis.
For these three models, the approximately optimal sample size for the next stage as a function of the current Fisher information and the stage cost is determined.
The authors assume availability of job history information, and the staging area imposes additional costs that have to be met by either the IPs or end users.
Information on grade and stage of cancers was not made available.
The retrieved information about comorbidity and stage of the disease made an extensive preoperative risk and tumor load comparison possible.
Analysis was limited to this period because detailed and reliable information on histology and stage is not available for patients diagnosed before 1993.
Demographic characteristics and information about stage, tumour size and grade, oestrogen receptor (ER) status, progesteron receptor (PR) status, surgery status, and chemotherapy and hormone therapy for first course of treatment was also obtained.
Cancer registry data included cancer diagnosed, diagnosis date, morphology code, grade, and stage information.
To reveal issues amenable to quality improvement we examined how interventions used to deliver LN staging information, and the characteristics of LN staging practice, physicians, and their environment contributed to changes in practice.
