Health information on the Internet

Health information on the Internet refers to all health-related information communicated through or available on the Internet.

Description

The Internet is widely used by the general public as a tool for finding health information.^[1] In the late 1990s, researchers noted an increase in Internet users' access to health-related content despite the variation in the quality of information, level of accessibility, and overall health literacy.^[2] Access to health information does not guarantee understanding, as health literacy of individuals vary.

It is believed patients who know their medical history may learn and interpret this information in a way that benefits them.^[3] This, however, is not always the case because online health information is not always peer reviewed.^[2] Physicians worry that patients who conduct Internet research on their medical history are at a risk of being misinformed.^[4][5] In 2013, the opinions about the relationship between health care providers and online health information were still being established.^[6] According to a 2014 study, "The flow of information has fundamentally changed, and physicians have less control over health information relayed to patients. Not surprisingly, this paradigm shift has elicited varied and sometimes conflicting views about the value of the Internet as a tool to improve health care."^[7]

Importance of the physician-patient relationship

In cases in which a physician has difficulty explaining complicated medical concepts to a patient, that patient may be inclined to seek information on the internet.

Social forums in which anyone can have conversations about health with their peers exist; these are especially popular among patients who want to talk about shared medical concerns with others.^[14] Those who participate in online communities that discuss health issues report feeling relieved about their health worries, perceiving they have more control over their health and medical condition, gaining more medical knowledge, and having more personal agency overall.^[15]

Some research studies have failed to find evidence to validate the physicians' concerns about patients receiving misinformation online or using online health information to conduct self-diagnosis.^[14][16][17] Patients with chronic diseases who use the Internet to get health-related information often acquire good skills to judge the quality of information that they find.^[18]

Social media platforms are considered channels physicians can use to acquire insight on their patients' thoughts.^[19] Patients have increasingly turned to social media for health information, sometimes of dubious quality.^{[20][21][22][23]} Several studies have used social media to gather data on patients' adverse drug reactions (ADRs) with generally promising results.^[24]

Some commercial organizations use health information gathered from the Internet, raising serious ethical and privacy concerns,^[25][26] including the risk of accidental violations of the patient privacy by healthcare providers.^[27][28]

Academic medical literature

The written record of peer-reviewed medical consensus is stored in scientific journals. There has been an academic journal publishing reform since the advent of electronic publishing. Although some journals have adopted an open access template for online users,^[29][30] other journals are opposed to a widening of open access publishing.^[31] The open-access policy has significantly increased the accessibility of professional health information to researchers, physicians, and the public through the Internet. Some of the academic medical literature, however, may not be peer-reviewed^[32][33] and users are advised to exercise caution when reading health-related articles from such websites.^{[citation needed]}

Quality

The nature of health-related information available on the Internet is complex and its quality varies greatly by source.^{[34][35][36][37]} The standards for ensuring quality control on the Internet have been criticized^{[citation needed]} and no single standard is universally accepted.^[38] Many researchers have investigated this issue in detail, resulting in a wide range of theories from different disciplines.^{[citation needed]}

One study found that a correct diagnosis given by the average online symptom checker happened only 34% of the time.^[39] Triage recommendations (i.e., whether immediate, normal, or self-type of care is needed) were also assessed and found to be correct 50% of the time.^[40] Quality of health information on the internet becomes important in this context as both misdiagnosis and inaccurate recommendations for triage are possible. Additionally, most online diagnostic tools fail to account for the user's familial and personal medical history, including current diagnoses and conditions they possess.^{[citation needed]}

Personal health information

For many applications, people wish to use health information on the Internet to gain further insight about a personal health concern. Because of this, the goal is often to use the Internet to find information as it is described in a person's medical record.

As of 2000[update], there is a broad international debate about ways to balance patient and commercial medicine demands for personal health information with an individual's needs for safety and respect.^[44][45]

Electronic medical records

An electronic medical record is a medical record stored on electronic media,^[46] for example, computer servers or hard-drives.

De-identification

De-identification is an attempt to remove patients' identifiable information from their medical records with the intent of making the information transferable without compromising patients' identities ^[
