Telemedicine provides healthcare at a distance using telecommunications technology. It has grown from focusing on increasing access to now emphasizing convenience and cost reduction. Store-and-forward and home-based telemedicine have evidence for treating chronic diseases, while office/hospital telemedicine is effective for verbal interactions in specialties like neurology and psychiatry. Current trends include expanding telemedicine to more chronic conditions and migrating services from clinical settings to homes and mobile devices. However, reimbursement remains limited and fragmented while quality of remote care compared to in-person visits requires more evidence. Proper guidelines, standards, training and balancing innovation with risk-based regulation can maximize telemedicine's benefits while minimizing harms.
This document discusses digital health transformation and the role of health information technology. It begins by exploring concepts like artificial intelligence, blockchain, cloud computing and big data. It then examines the potential for "smart" machines in healthcare while acknowledging the complexities of digitizing such a system. The document emphasizes that clinical judgment is still necessary given variations in patients. It outlines components of healthcare systems and forms of health IT both within and beyond hospitals. Finally, it discusses using health IT to support clinical decision making and reduce errors.
Presented at The Thai Medical Informatics Association Annual Conference and The National Conference on Medical Informatics (TMI-NCMedInfo) 2021, Bangkok, Thailand on November 26, 2021
The document discusses the field of health informatics and provides definitions and examples. It defines health informatics as the application of information science to healthcare and biomedical research. It describes the relationships between health informatics and other fields like computer science, engineering, and the medical sciences. The document also discusses different areas of health informatics like clinical informatics, public health informatics, and consumer health informatics. It provides examples of common health information technologies used in healthcare settings like electronic health records, computerized physician order entry, and picture archiving systems.
This document provides an introduction to research ethics and ethics for health informaticians. It begins with definitions of ethics, morals, and norms. It then discusses the role of law, professional codes of conduct, and ethics in establishing standards of acceptable behavior. Key topics in research ethics are introduced through discussions of historic cases like the Nazi human experiments, Beecher's research ethics violations, and the Tuskegee Syphilis Study. The document outlines the Belmont Report's three ethical principles of respect for persons, beneficence, and justice. Ethical issues in health informatics like alerts fatigue from clinical decision support systems and unintended consequences of health IT are also discussed.

23. Need for Strong Password Policy
So, two informaticians
walk into a bar...
The bouncer says,
"What's the password."
One says, "Password?"
The bouncer lets them
in.

Access control based on the person’s role
(rather than identity)
Audit trails

sequence of activities

Identifying who you are
Usually done by user IDs or some other unique codes
Authentication
Confirming that you truly are who you identify
Usually done by keys, PIN, passwords or biometrics

Determined based on system owner’s policy & system
configurations
“Principle of Least Privilege”

28. Recommended Password Policy
Length
8 characters or more (to slow down brute-force attacks)
Complexity (to slow down brute-force attacks)
Consists of 3 of 4 categories of characters
Uppercase letters
Lowercase letters
Numbers
Symbols (except symbols that have special uses by the
system or that can be used to hack system, e.g. SQL Injection)
No meaning (“Dictionary Attacks”)
Not simple patterns (12345678, 11111111) (to slow down brute-
force attacks & prevent dictionary attacks)
Not easy to guess (birthday, family names, etc.) (to prevent
unknown & known persons from guessing)
Personal opinion. No legal responsibility assumed.
29. Recommended Password Policy
Expiration (to make brute-force attacks not possible)
6-8 months
Decreasing over time because of increasing computer’s
speed
But be careful! Too short duration will force users to write
passwords down
Secure password storage in database or system
(encrypted or store only password hashes)
Secure password confirmation
Secure “forget password” policy
Different password for each account. Create variations
to help remember. If not possible, have different sets of
accounts for differing security needs (e.g., bank
accounts vs. social media sites) Personal opinion. No legal responsibility assumed.
32. Techniques to Remember Passwords
http://www.wikihow.com/Create-a-Password-You-Can-
Remember
Note that some of the techniques are less secure!
One easy & secure way: password mnemonic
Think of a full sentence that you can remember
Ideally the sentence should have 8 or more words, with
numbers and symbols
Use first character of each word as password
Sentence: I love reading all 7 Harry Potter books!
Password: Ilra7HPb!
Voila!
Personal opinion. No legal responsibility assumed.
