Johns Hopkins Research Finds that Data Mining of Health Records useful to Reduce Physician and Treatment Mistakes Diagnostic errors are one of the biggest patient safety issues we face in healthcare and these very often lead to medical errors. It is often caused by a diagnosis that is missed, wrong or delayed, as detected by some later definitive test or finding. These costly errors can result in delay or failure to treat a condition, or to provide treatment for a condition that doesn’t actually exist. On evaluating 25 years of U.S. malpractice claim payouts, Johns Hopkins University researchers found that diagnostic errors are the reason for death or permanent damage for around 160,000 patients every year. These errors are also the leading reason for malpractice claims that are paid to physicians. The notable thing is that diagnostic errors are more easily preventable than any other medical mistakes. Automation is a practical solution that can address this problem. Computers can be used to check medical records and identify possible errors, and also to prompt doctors to follow up on risky test results. Helpful online services that can assist doctors with diagnoses and tests/devices that can help them identify conditions/illnesses more accurately are other solutions. Doctors are being made aware of the risk involved in holding on to one diagnosis and not looking further. They need to keep an open mind in cases that appear confusing with conflicting evidence. The new healthcare law that lays emphasis on coordinated care is expected to improve diagnosis while also ensuring that patients consult specialists when they are required to do so. Effort is on to develop techniques that can identify and measure diagnostic errors. Data mining from electronic records can help identify information such as lab results that may have escaped notice. Data mining is one of the powerful techniques available for accurate disease diagnosis. When a large amount of medical data is available, more powerful data analysis tools can be used to mine useful information. For example, researchers are employing statistical and data mining tools to assist healthcare providers diagnose heart disease accurately. Data mining techniques are also employed for the prevention of diseases such as cancer, stroke, cardiac arrest, and diabetes. It helps in the prevention of hospital errors, in early detection and prevention of diseases, and in the detection of fraudulent insurance claims.
