He has also served on the board of directors of two public companies, Columbia Bank, and Lifeco, a holding company which owned a life insurance company & a broker-dealer. .

Dr. Hendler developed two tests to control workers compensation, and auto accident costs for self insured companies, TPAs, reinsurance companies, nurse case managers, plaintiff & defense attorneys., for B2B tests in English & Spanish for B2C, for website in English, Spanish, Italian, Russian, German, Portuguese, Arabic, & French.

One Internet test identifies claimants who are faking their workers compensation or auto accident claims, with 85% accuracy. The other test provides proper diagnosis for chronic pain patients, who are misdiagnosed 40%-67% of the time. Using the tests have resulted in documented cost savings between $20,000 to $175,000, with 90% reduction in narcotic use, 45% reduction in doctor visits, and increase return to work rates.The test is now used by the largest pre-employment testing company in the US, which does 100,000 tests a year.



Maryland Clinical Diagnositcs

March 2006 - Present

Our company has a number of Internet based "expert systems," developed by former staff members from Johns Hopkins Hospital, using pattern recognition, Bayesian analysis, and predictive analytic techniques, These artificial intelligence (AI) products replicate and improve upon physician diagnostic techniques. For the 40%-80% of chronic pain patients who are misdiagnosed, we have an expert system which gives diagnoses with a 96% correlation with diagnoses of Johns Hopkins Hospital doctors. We have documented cost saving of 54% on workers compensation cases ($20,000 to $175,000 a case). To combat the current opioid crisis, we have the Pain Validity Test which can predict with 95% accuracy who will have abnormalities on medical testing (a valid complaint of pain) and predict with 93% accuracy who will not have abnormalities (drug seeking behavior, fakers, malingerers). This test has been admitted as evidence in 8 states. We have duplicated the Ottawa Ankle and Knee Rules, which saved $50,000,000 a year on unnecessary X-rays in just the city of Ottawa alone, and we have a system for neck, back and limb pain which can predict which medical test will be abnormal, when compared to our benchmark population. As an example, the MRI, CT and X-ray can detect abnormalities only at the 12%-32% level compared to facet blocks, root blocks and provocative discograms which detect pathology at the 57%-87% level. Companies can eliminate costly and inaccurate medical tests, while improving patient care, as documented by our outcome studies. We have just completed a diagnostic test for headache, since 35%-70% of people told they have "migraine" do not have it, and "chronic daily headache" is not a diagnosis, but a useless and worthless description of a patient's complaints.
