Impact of Hospital-based Multidisciplinary Anticoagulation Stewardship Programs.

Antithrombotic therapies, especially anticoagulants, are high-risk medications with increased potential for adverse events. The development and implementation of a well-functioning, designated, multidisciplinary anticoagulation stewardship program (MASP), tailored to each hospital-center's needs, has the primary objectives of improving patient-centered outcomes, minimizing undesirable anticoagulation-related adverse events and minimizing hospital length of stay (LOS) and other patient-related costs. Such stewardship programs are pivotal in supporting busy clinicians with consultation on challenging clinical case scenarios, ensuring appropriate use of valuable healthcare resources, achieving compliance with anticoagulant-associated accreditation standards, and positively impacting patient-specific morbidity/mortality outcomes.

The burned patient in times of COVID-19: proposal derived from lessons learned.

COVID-19 is a public health problem, so any burn patient who is managed as an outpatient or requires hospital management is a potential carrier of SARS-CoV-2. Burn patients are susceptible to COVID-19 due to the burn and its immunosuppressive effect, the procedures they undergo and other factors related to the burn, which makes them at high risk of contracting the disease and transmitting it, especially to the healthcare team involved in its management. Therefore, it is important to organize strategies in the services that care for burn patients during the COVID-19 pandemic.
