Measurement of Corneal Hysteresis for the Diagnosis and Management of Glaucoma

December 6, 2018 Medical Technology Directory

Health Problem: Glaucoma is a group of ocular disorders that causes progressive damage to the optic nerve, which results in loss of vision. Glaucoma is the second leading cause of blindness worldwide, with as many as 6 million people blind in both eyes due to this condition. In the United States, more than 3 million people have glaucoma, among whom up to half are unaware that they have the disease. Technology Description: Glaucoma causes changes in the physical properties of the eye that tend to make the cornea less flexible, which reduces corneal hysteresis (elasticity) and increases corneal stiffness. Corneal hysteresis...

Comparative Effectiveness Review of Endoscopic Surgery for Carpal Tunnel Release: A Review of Reviews

November 30, 2018 Medical Technology Directory

Health Problem: Carpal tunnel syndrome (CTS) is a compression neuropathy of the median nerve at the wrist. It is characterized by increased pressure within the carpal tunnel and decreased function of the nerve. The estimated prevalence of CTS is 3.1% to 7.8% among adult workers, with higher prevalence among female and older-age workers. Technology Description: Surgery for CTS is referred to as carpal tunnel release, which involves decompression of the carpal tunnel by cutting through the ligament pressing down on the carpal tunnel. The primary approaches to carpal tunnel release are conventional open carpal tunnel release (OCTR) or endoscopic carpal tunnel...

Comparative Effectiveness Review of Patellofemoral Arthroplasty for Isolated Osteoarthritis of the Knee

November 27, 2018 Medical Technology Directory

Health Problem: Osteoarthritis (OA) refers to the destruction of cartilage, the protective covering overlying bones at joints such as the knee or hip. Isolated patellofemoral OA (PFOA) involves only the junction between the kneecap (patella) and the distal thighbone (femur). PFOA is caused by trauma, malalignment of the joint, age-related degeneration, congenital trochlear dysplasia, and other factors. Symptoms of PFOA may include pain, swelling, inflammation, muscle weakness, impaired quality of life, and reduced function. In a symptom-based cohort, the prevalence of isolated PFOA was 8% compared with 27% of individuals with combined PFOA and tibiofemoral OA. Technology Description: Patellofemoral arthroplasty (PFA)...

Pneumatic Compression for Prevention of Deep Vein Thrombosis Following Knee Arthroplasty

November 20, 2018 Medical Technology Directory

Health Problem: A venous thromboembolism (VTE) is a blood clot resulting from slowed circulation, which includes both deep vein thrombosis (DVT) and pulmonary embolism (PE). A DVT forms in a deep vein, usually the leg or pelvis, increasing the risk of morbidity and mortality after orthopedic surgery. Following total knee arthroplasty (TKA), 40% to 84% of patients develop a DVT, which poses a risk for PE. There is a 1-month mortality rate of 6% for DVT and 12% for PE. Technology Description: Pneumatic compression (PC) devices are comprised of an inflatable garment for the leg and an electrical or battery-powered pneumatic...

Electronic Monitoring Versus Direct Observation of Hand Hygiene Compliance in Healthcare Settings

November 15, 2018 Medical Technology Directory

Health Problem: Healthcare-associated infections (HAIs) are infections that patients acquire in a healthcare setting and are largely preventable, chiefly through adequate hand hygiene (HH). Compliance with HH guidelines can remain lax. Hospitals often assess HH compliance via direct observation (DO) by trained observers. DO has limitations in that it is costly and time consuming, requires training, measures only a small portion of HH opportunities, and has interrater variability issues. Technology Description: Electronic HH monitoring systems monitor potential HH opportunities and/or events and vary in their degree of sophistication. The simplest are straightforward counters that record the number of times an antiseptic...
