I wasn’t too surprised reading the other day that health-related matters take up 2% of all queries on internet search engines. In fact, I thought the figure would be higher, judging from day-to-day conversations with patients.
The big question of course is: how reliable are the facts dished out on the Internet? Obviously, its important that these websites are reliable and churn out accurate information. Even so, healthcare information is complicated by a few other factors not related to the reliability of these websites, as explained later.
How do you identify reliable websites? First of all, as a yardstick, websites sponsored by the governments, not-for-profit health or medical organizations, and university medical centers are the most reliable resources on the Internet. Sites supported by for-profit drug companies, for instance, who may be trying to sell you their products, are usually not your best option. Also note that medical info changes rapidly with time and a look at the dateline of the article is important. Here are a few such sites:
Medlineplus.gov – sponsored by the National Institutes of Health and managed by the U.S. National Library of Medicine, MedlinePlus provides information on more than 900 diseases and conditions in their “Health Topics” section, and links to other trusted resources.
WebMD provides a wealth of health information and tools for managing your health from an award-winning website, which is continuously reviewed for accuracy and timeliness.
MayoClinic.com – owned by the Mayo Foundation for Medical Education and Research, this site is produced by more than 3,300 physicians, scientists and researchers from Mayo Clinic, and provides in-depth, easy-to-understand information on hundreds of diseases and conditions, drugs and supplements, tests and procedures.
Sometimes,even with reliable trustworthy information, its rather difficult for the untrained public to give due weightage to the complex info that is being bombarded onto them. For instance, when reading the side-effects of a particular medication, it is difficult to appreciate that not all the listed side-effects will invariably occur when one consumes the drug.
This is why its better to consult a doctor to obtain clarification. It takes years of medical training to adequately decipher fully what’s found on web health-sites and to fully appreciate its implications.
In fact, the over-reliance of info on the internet has given rise to a new condition called cyberchondria (aka internet self-diagnosis) – this refers to the practice of leaping to dire conclusions while researching health matters online. If that severe headache haunting you in the morning led you to the Web search-engine and a search on ‘headaches’ led to ‘brain tumours’ or ‘meningitis’, people tend to look at the first few results in the search-engine which forms the basis for them to probe further till they are convinced that they have a brain tumour. The likely diagnosis is probably cyberchondria than anything else! The phenomenon has become so pervasive that Microsoft did its own study on the causes of cyberchondria way back in 2008.
The cost of healthcare delivery continues to rise unabated due to many factors, estimated to be at least 10% year-on-year. Some of the reasons are pretty obvious, such as newer medications where extensive research has been undertaken and new technology.
Costs aside, one can forsee that, in the near future, some trends in the way healthcare is provided, are emerging.
Take a look, for instance, at electronic health records – storing a patient’s medical history, medications, lab work and recent tests in the computer so that there is record sharing to improve safety and for convenience for patients. Throw away the thick patient folders and time-wasting in deciphering doctors’ handwriting!
Telehealth has also made great inroads, especially in rural or remote areas. Telecommunications technology (read ‘internet’) is used to provide and support in-home health care for those not easily reached.
Quite a new concept is that of the medical home, not a name for a building but more of a concept of medical care, where a primary care provider, like a GP,takes the lead on coordinating all aspects of a patient’s care, be it surgical wound dressings, flu shots, blood tests or emotional health. This avoids duplication of medications when a patient is seeing multiple doctors for various ailments.
Integrative medicine — The combining of conventional Western medicine with alternative treatments like acupuncture,homeopathic medicine have already entrenched themselves into some societies When conventional medicine doesn’t bring relief, more people are trying acupuncture, botanical remedies, dietary supplements or stress reduction techniques for help, thus addressing the patient as a whole person, not a person suffering from just one disease.
Of all recent trends I’ve noticed, the one that has the greatest potential, to my mind, is individualised medicine – the tailoring of treatment for a disease to each patient’s specific needs based on that patient’s gene profiling. After all, it does make sense – one pill does not fit all – that individual variations make it necessary to tailor doses and type of medications to one’s genetic makeup. By identifying the genetic makeup of an individual, doctors and reduce or increase doses of a particular medicine to give maximum effect minus the side-effects. In some leading medical centres, like Mayo Clinic, there are even Centres for Individualized Medicine. See here.
