Intensive Care Unit Nurses' Beliefs About Delirium Assessment and Management.

Delirium, the most frequent complication of hospitalized older adults, particularly in intensive care units (ICUs), can result in increased mortality rates and length of stay. Nurses are neither consistently identifying nor managing delirium in these patients. The purpose of this study was to explore ICU nurses' identification of delirium, actions they would take for patients with signs or symptoms of delirium, and beliefs about delirium assessment and management. In this cross-sectional study using qualitative descriptive methods guided by the theory of planned behavior, 30 ICU nurses' responses to patient vignettes depicting different delirium subtypes were explored. Descriptive and content analyses revealed that nurses did not consistently identify delirium; their actions varied in different vignettes. Nurses believed that they needed adequate staffing, balanced workload, interprofessional collaboration, and established policy and protocols to identify and manage delirium successfully. Research is needed to determine if implementing these changes increases recognition and decreases consequences of delirium.

The evolution of Clostridium difficile infection in cancer patients: epidemiology, pathophysiology, and guidelines for prevention and management.

Clostridium difficile infection (CDI) has emerged as a significant challenge to the healthcare system. The availability of anti-cancer chemotherapeutic regimens has contemporaneously resulted in a larger population of patients who are susceptible to CDI. The outbreak of a novel, hypervirulent, resistant strain, NAP-1/027 as well as resistance to antibiotic therapy have further contributed to an increase in prevalence as well as in disease severity. Recent data show high fatality rates in cancer patients with CDI. In this review, we have discussed the incidence, epidemiology, pathophysiology, clinical signs and symptoms and therapeutic guidelines for patients who are on chemotherapy and present with CDI and highlighted clinical reports documenting severe CDI associated with chemotherapeutic agents such as methotrexate, 5FU, cisplatin, carboplatin, paclitaxel, vinorelbine and cyclophosphamide. The review article also has the discussion of patents pertaining to infections caused by Clostridium difficile in cancer patients. We underscore the urgent need for early recognition and diagnosis of CDI in cancer patients and for the design and implementation of randomized clinical trials of new treatment modalities in the management of chemotherapy- associated CDI.
