Design Example: Analyzing Capacity Contours for Flood Risk Assessment01:17

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...
Guidelines and Strategies for Safe Computer Charting01:18

Guidelines and Strategies for Safe Computer Charting

The guidelines and strategies provided by the American Nurses Association (ANA) and the Canadian Nurses Association (CNA) offer essential principles for ensuring safe and secure computer charting systems in healthcare settings. Let's break down each recommendation:

Types 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...
Relative Risk01:12

Relative Risk

Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...
SBAR II: Application of SBAR01:14

SBAR II: Application of SBAR

SBAR is an effective communication tool used by healthcare professionals to communicate patient information accurately. SBAR stands for Situation, Background, Assessment, and Recommendation. For a better understanding, an example is given below.
SBAR Report from a Nurse to a Health Care Provider

Area of Science:

  • Medical Informatics
  • Information Systems Security
  • Risk Management

Background:

  • Effective risk management in medical information systems requires adherence to international standards.
  • Current challenges include a lack of intuitive tools to bridge regulatory frameworks and daily practice.

Purpose of the Study:

  • To design, implement, and evaluate a browser-based tool for visual risk modeling and assessment in medical informatics.
  • To address the need for accessible tools connecting regulatory requirements with operational workflows.

Main Methods:

  • The study employed the Design Science Research framework across three phases: requirements/design, implementation, and evaluation.
  • A browser-based tool was developed enabling process modeling, hazard list management, and structured risk assessments.
  • Expert evaluation involved four medical informatics professionals assessing usability via the System Usability Scale.

Main Results:

  • The developed tool facilitates process modeling with simplified notation and structured risk assessments.
  • Expert evaluation yielded high usability ratings (83.75) on the System Usability Scale.
  • The tool effectively supports process-oriented risk assessment in medical informatics.

Conclusions:

  • Browser-based, interactive tools can significantly improve risk management in medical informatics.
  • The developed tool offers a systematic and collaborative approach to managing risks in healthcare information systems.
