Disease management necessarily draws upon information about the safety, effectiveness, and appropriateness of the set of alternative or complementary health care interventions that may be involved in the management of a particular condition. Further, disease management emphasizes programmatic implementation, monitoring, and capitation arrangements. There are multiple reasons for this. For any assessment effort, there are resource limitations that weigh against the diminishing returns of seeking every potentially useful citation. Authors have many ways of writing about various types of evaluation studies.
Indexers attempt to reflect the subject content of the article as it is written.
Although bibliographic database managers such as NLM continue to work to narrow this gap, they have more control over the time between publication and citation entry than the time between assessment completion and publication. NLM continues to improve the efficiency of its indexing and related citation management processes. Further, NLM has taken steps to provide information about certain projects whose findings are not yet published. The new HSRProj database provides descriptions of ongoing projects in the related field of health services research, including certain health technology assessment efforts. Tradeoffs are inherent in the process of gathering evidence for health technology assessments.
