Usability: deals with specific issues of human performance during computer interactions for specific tasks within a particular contest.
- refers to how well the information system product was designed for users to learn as well as to use.
- refers to how the system allows users to carry out their tasks safely, effectively, and pleasantly.
- is related to the human-centered design that is characterized by the active involvement of users and the clear understanding of user and task requirements
Usability testing: creating realistic clinical scenarios to which end users are asked to apply configured electronic tools, using the hardware that will be used in production.
The usability of a system can be measured by:
- Effectiveness (can users successfully achieve their objectives?)
- Efficiency (how much effort and resource are expended in achieving those objectives?)
- Satisfaction (was the experience considered satisfactory?)

Ergonomics is the science of designing a work environment so that it is convenient to use and does not prove injurious to health. It is used in the United States to describe the design and implementation of equipment, tools, and machines related to human safety, comfort, and convenience.
- It is the study and design of a work environment that maximizes productivity by reducing operator fatigue and discomfort.
- It considers physical stresses placed on joints, muscles, nerves, and tendons as well as environmental factors that can affect hearing and vision.
- Poor setup of computer equipment leads to somatic complaints that include headaches, eyestrain, irritation, stress, fatigue, and neck and back pain.

What is mHealth?
The National Institutes of Health (NIH) Consensus Group defined mHealth as “the use of mobile wireless communication devices to improve health outcomes, health care services, and health research”. It is a recent term used to encompass the use of mobile devices, such as mobile phones, patient-monitoring devices, PDAs, and other wireless devices, to support medical and public health practice.
mHEalth applications, include the use of mobile devices in collecting community and clinical health data, delivery of healthcare information to practitioners, researchers, and patients; real-time monitoring of patient vital signs; and direct provision of care (via mobile telemedicine). It can enhance diagnosis, help prevent diseases, improve treatments, improve accessibility to health care, and advance health-related research.

Temporal arteritis is a condition in which the temporal arteries supplying blood to the head and brain become inflamed or damaged. Temporal arteritis is also known as cranial arteritis or giant cell arteritis. Giant cell arteritis (GCA) is a segmental systemic granulomatous arteritis affecting medium and large arteries in individuals >50 yr. The inflammation primarily targets branches of the extracranial head and neck blood vessels (external carotids, temporal arteries, ciliary and ophthalmic arteries). The aorta and subclavian and brachial arteries can also be affected. Intracranial arteritis is rare (Ferri, 2018).
There are approximately 20 new cases of temporal arteritis for every 100,000 people over 50 years of age. Incidence increases with age with the highest rate being among those 70-79 years old, is more common in women than in men by 3:1 and is more often seen in Caucasians than any other race (Petri, Nevitt, Sarsour, Napalkov, and Collinson, 2015). There are no estimates of the prevalence of GCA in the United States population in the current millennium. Most cases are paired with a diagnosis of polymyalgia rheumatic (PMR).
