Patients who had undergone elective total hip or total knee replacement at hospitals with small surgical volume are likely to run into venous thromboembolism and may die following the procedure, Science Daily says. Complainants claiming they were impaired by faulty hip replacement implants are being heard in U.S. courts. However, the judge’s orders pave way for next phase in DePuy Pinnacle MDL hearings.
Venous thromboembolism (VTE) is a disease that includes both deep vein thrombosis (DVT) and pulmonary embolism (PE). It is a communal, lethal disorder that affects hospitalized and non-hospitalized patients, persists regularly, is often unnoticed, and results in long-term complications, including chronic thromboembolic pulmonary hypertension (CTPH) and the post-thrombotic syndrome (PTS), according to the Cleveland Clinic website.
Venous thromboembolism results from a amalgamation of hereditary and acquired risk factors, also known as thrombophilia or hypercoagulable states. In addition, vessel wall damage, venous stasis, and increased activation of clotting factors first described by Rudolf Virchow more than a century ago still remain the fundamental basis for our understanding of thrombosis, the Science Daily suggests.
The impediments following joint replacement surgery at low-volume sites may be reduced by modifying systems and procedures used before and after surgery, according to the findings published in Arthritis and Rheumatism, a peer-reviewed journal of the American College of Rheumatology (ACR).
The ACR estimations that about 27 million Americans over the age of 25 have doctor-diagnosed osteoarthritis and another 1.3 million US adults suffer with rheumatoid arthritis. For patients with end-stage hip and knee arthritis, total hip and knee arthroplasty are highly successful surgical interventions that offer patients significant improvement in pain, function and health-related quality of life. Based on the Centers for Disease Control and Prevention (CDC) National Hospital Discharge Appraisal, roughly 230,000 total hip replacements and 543,000 total knee replacements were done in the U.S. in 2007.
The present study explored the relationship between hospital procedure volume and surgical outcomes resulting primary total hip or total knee replacements. ”With the big sum of elective arthroplasty in the U.S, it is important to understand the impact of pre- and post-operative medical complications on the success of joint replacement surgery," said lead author Jasvinder Singh, MD, MPH of the University of Alabama.
Researchers found that for total knee arthroplasty, patients age 65 and older have had significantly higher odds for one-year mortality when surgeries were performed at low-volume hospitals compared to higher volume hospitals.
The authors’ hypothesis is that the reason of the complications at low-volume hospitals could be allied to hospital procedures and pre- and post-operative care processes. Conversely, it is best to be extra cautious to prevent any complications which may lead to the filing of Pinnacle lawsuit.
