Necrotizing fasciitis associated with malignancy

Chen, L. L., Tayban, K., Caravanos, C., Shaz, D., & Halpern, N. A. (2020). Journal of the American Association of Nurse Practitioners, 32(2), 109-112. 10.1097/JXX.0000000000000251
Necrotizing fasciitis (NF) is a rare soft-tissue condition with a high mortality rate even with treatment. Diagnosis is challenging due to an absence of specific symptoms at the early stages of clinical presentation. NF is typically associated with traumatic injuries, superficial skin breakdown, and surgical procedures. Diabetes mellitus and immunosuppression also increase the risk of developing NF. NF predominantly occurs in the lower extremities, the peritoneum, and the perineum. Treatments include antimicrobials, supportive care, and surgical source control. It is important for clinicians to recognize the association of spontaneous atraumatic NF caused by Clostridium septicum with malignancy, so they can maintain a high index of suspicion and provide timely interventions to optimize patient outcomes.

Necrotizing fasciitis: A comprehensive review

Necrotizing soft-tissue infections (NSTIs) are rare but rapidly progressive, life-threatening bacterial infections with high morbidity and mortality. NSTIs include necrotizing forms of fasciitis, myositis, and cellulitis. This article focuses on necrotizing fasciitis (NF) and discusses NF classifications, clinical features, diagnostic approaches, evidence-based treatments, and nursing interventions.

Standardized adult-gerontology acute care nurse practitioner point-of-care ultrasound training: A new perspective in the age of a pandemic

Chen, L. L. (2020). Journal of the American Association of Nurse Practitioners, 32(6), 416-418. 10.1097/JXX.0000000000000448
Our health care landscape is rapidly changing. With the aging population and seemingly increasing outbreak of communicable diseases, it is expected that there will be a continued demand for inpatient/critical care providers. The current COVID-19 pandemic provides a glimpse of a health care system in severe provider shortage. Adult-gerontology acute nurse practitioners (GACNPs) can play a vital part in relieving that shortage. But with the increased role, there is an increased responsibility and need for expansion of AGACNP skill set. This includes the training and utilization of point-of-care ultrasound (POCUS). The case reports and data available from countries that have already combated COVID-19 outbreak show POCUS can play a key part in managing critically ill patients on isolation precautions. This article provides my perspective on POCUS training and competency achievement for AGACNPPs.
