Summary
Identifying health economic evaluation studies requires a combined search of the National Health Service Economic Evaluation Database (NHS EED) and PubMed. This strategy ensures comprehensive retrieval for health technology assessment projects.
Area of Science:
- Health Economics
- Health Technology Assessment
- Bibliometrics
Background:
- The number of published health economic evaluation studies has grown significantly.
- Health technology assessment (HTA) projects frequently encounter a lack of relevant studies.
- Efficient identification strategies are crucial for HTA and policy-making.
Purpose of the Study:
- To determine the optimal method for identifying all relevant published health economic evaluation studies.
- To address the challenge of study scarcity in HTA projects.
Main Methods:
- Conducted a systematic search across six bibliographic databases.
- Developed and applied individually adapted search strategies.
- Utilized inclusion and exclusion criteria, exemplified by cost-effectiveness of gastroesophageal reflux disease diagnosis.
Main Results:
- After screening and deduplication, 68 abstracts were reviewed.
- 41 studies were selected for full-text review, identifying 14 relevant papers.
- The National Health Service Economic Evaluation Database (NHS EED) and PubMed yielded the most relevant studies.
Conclusions:
- A combined search of NHS EED (via Cochrane Library or CRD) and PubMed is an effective and cost-efficient strategy.
- Supplementary PubMed searches are necessary due to inconsistent indexing of 'cost-effectiveness' as a Medical Subject Heading (MeSH).
- Utilizing all relevant economic search terms in PubMed is essential for complete identification.

01:15Nursing Evaluation
The evaluation stage signals the end of the nursing process. The nurse gathers evaluative data to assess whether or not the patient has attained the expected results. Whereas the nurse collects data in the nursing assessment to identify the patient's health concerns, the evaluation stage data determines if the indicated health issues are resolved. Evaluative data collection includes two sections: the data acquired to evaluate patient outcomes and the time criteria for data collection.

01:23Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast, controlled...

01:12Hazard Ratio
The hazard ratio (HR) is a widely used measure in clinical trials to compare the risk of events, such as death or disease recurrence, between two groups over time. It reflects the ratio of hazard rates—the instantaneous risk of the event occurring—between a treatment group and a control group. This measure provides valuable insights into the relative effectiveness of a treatment by assessing how the risk of an event differs between the two groups.
For example, in a clinical trial evaluating a...

01:26Introduction to Epidemiology
Epidemiology, known as the cornerstone of public health, involves studying the distribution and determinants of health-related events in defined populations and applying these insights to control health issues. This is essential for understanding how diseases spread, identifying populations at greater risk, and implementing measures to control or prevent outbreaks. Epidemiology addresses not only infectious diseases but also non-communicable conditions like cancer and cardiovascular disease,...
01:30Methods of Documentation VII: EMR
Electronic Medical Records (EMRs) primarily center around electronically documenting patients' health information within a single healthcare organization or practice. They contain essential clinical data related to a patient's medical history, diagnoses, medications, treatment plans, lab results, and other pertinent information relevant to the specific encounter or episode of care. EMRs are designed to streamline documentation and workflow processes within individual healthcare settings,...
