Methods of Documentation III: PIE01:21

Methods of Documentation III: PIE

1.8K
Problem-intervention-evaluation (PIE) is a systematic approach to documentation used in healthcare settings for clinical decision-making and patient care planning. It is a structured approach to organizing patient data based on problems, interventions, and evaluations. Here's a breakdown of its key features and considerations:

Methods of Documentation II: POMR

1.2K
The Problem-Oriented Medical Record (POMR) revolutionized medical record-keeping by introducing a systematic approach focusing on the patient's problems rather than merely listing symptoms. Dr. Lawrence Weed's introduction of this method in the 1960s marked a significant advancement in medical documentation. The POMR framework consists of four key components: the database, problem list, plan of care, and progress notes.

Design Example: Resistive Touchscreen

561
A device engineer plays a crucial role in designing user interfaces for mobile devices. One such interface is the resistive touchscreen, which fundamentally consists of two metallic layers: a flexible upper layer and a rigid lower layer, separated by a narrow gap. The high resistance between these two layers is a key characteristic of this design.
When a user touches the screen, the two layers make contact at a specific point known as the touchpoint. This contact reduces the resistance between...

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

Glaucoma: Overview01:25

Glaucoma: Overview

1.1K
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Area of Science:

  • Human-Computer Interaction
  • Web Accessibility
  • Assistive Technology

Background:

  • Sighted users easily navigate web content using visual cues and pointing devices.
  • Blind users rely on screen readers, making interaction with lengthy documents tedious due to serial navigation.
  • A usability gap exists in web document interaction for blind users.

Purpose of the Study:

  • To introduce iTOC, a browser extension designed to enhance web accessibility for blind users.
  • To provide blind users with instant, on-demand access to Tables of Contents (TOCs) within web documents.
  • To bridge the interaction divide between sighted and blind users of web content.

Main Methods:

  • Developed iTOC, a browser extension that automatically extracts TOC hyperlinks from web documents.
  • Implemented a feature for instant screen-reader access to the extracted TOC from any point on a webpage.
  • Conducted a user study with 15 blind participants to evaluate iTOC's effectiveness.

Main Results:

  • iTOC significantly reduced content access time for blind users by up to 42.73%.
  • User effort, measured by input actions, was lowered by as much as 57.9% compared to existing solutions.
  • The study demonstrated iTOC's effectiveness in improving web usability for screen reader users.

Conclusions:

  • iTOC offers a substantial improvement in web navigation efficiency and user experience for blind individuals.
  • The browser extension effectively addresses the challenges faced by screen reader users with long web documents.
  • iTOC represents a significant advancement in assistive technology for web accessibility.
