Summary
Health technology assessment (HTA) extensively uses graphics, but lacks standardization. This study proposes a structured approach to improve information graphic design in HTA reports for better decision-making.
Area of Science:
- Health Technology Assessment (HTA)
- Information Visualization
- Decision Science
Background:
- Health technology assessment (HTA) reports in the UK utilize graphical tools, though less frequently than tables.
- Current use of information graphics in HTA literature shows wide variation across report sections and research centers.
Purpose of the Study:
- To investigate the current use of information graphics in UK Health Technology Assessment (HTA) outputs.
- To propose a structured approach for designing effective information graphics in HTA, considering stakeholder decision-making needs.
Main Methods:
- A scoping review of HTA reports was performed.
- Content analysis of graphical figures in 50 recent UK National Health Service HTA reports using a classification framework (report section, graphical type, research center).
Main Results:
- Information graphics are widely used in HTA reports, but their application is conventional with little innovation.
- Significant variance exists in the quantity of graphics used by different research centers authoring HTA reports.
Conclusions:
- While HTA extensively uses graphics, a systematic or standardized approach is lacking.
- There is substantial potential for innovation in information graphics for HTA, alongside existing research challenges.
- A contextually based, structured design approach for HTA information graphics is proposed to guide application and innovation.

01:29Nursing Assessment
The two sources for collecting information are primary and secondary. After gathering information, interpretation and validation help to complete the data. The purpose of assessment is to establish data with the initial information, to interpret data about the patient's perceived needs and health problems, and to respond to these problems identified.
The nurse collects all aspects of the patient's health in the initial assessment, establishing priorities for ongoing focused assessments and...

01:19Overview of Biostatistics in Health Sciences
Biostatistics involves the application of statistical techniques to scientific research in health-related fields, including biology and public health. These techniques are essential for designing studies, collecting data, and analyzing it to draw meaningful conclusions. Given the complexity of biological processes, particularly in studies involving human subjects, biostatistical methods are crucial for effectively organizing and interpreting data that might otherwise obscure underlying patterns...
01:11Purpose of Health Records I
The vital purpose of health records is to provide a complete and accurate account of a patient's medical history, including communication, diagnostic and therapeutic orders, care planning, research, and quality review.

The case management model is a multidisciplinary approach that involves healthcare professionals from diverse disciplines, such as physicians, nurses, therapists, social workers, and pharmacists, working collaboratively to address the various needs of patients. Each healthcare professional brings unique expertise and perspectives, contributing to a more comprehensive understanding of the patient's condition and tailoring treatment plans accordingly.
