Eye-tracking to observe compliance with hand hygiene in the intensive care unit: a randomized feasibility study.

BACKGROUND: Healthcare-associated infections are associated with increased patient mortality. Hand hygiene is the most effective method to reduce these infections. Despite simplification of this easy intervention, compliance with hand disinfection remains low. Current assessment of hand hygiene is mainly based on observation by hygiene specialists. The aim of this study was to investigate additional benefits of eye-tracking during the analysis of hand hygiene compliance of healthcare professionals in the intensive care unit. METHODS: In a simulated, randomized crossover study conducted at the interdisciplinary intensive care unit at University Hospital Zurich, Switzerland, doctors and nurses underwent eye-tracking and completed two everyday tasks (injection of 10 µg norepinephrine via a central venous line, blood removal from the central line) in two scenarios where the locations of alcoholic dispensers differed ('in-sight' and 'out-of-sight'). The primary outcomes were dwell time, revisits, first fixation duration and average fixation duration on three areas of interest (central venous line, alcohol dispenser, protective glove box) for both scenarios. Compliance with hand hygiene guidelines was analysed. FINDINGS: Forty-nine participants (35 nurses, 14 doctors) were included in this study. Eye-tracking provided additional useful information compared with conventional observations. Dwell time, revisits, first fixation duration and average fixation duration did not differ between the two scenarios for all areas of interest. Overall compliance with recommended hand hygiene measures was low in both doctors (mean 20%) and nurses (mean 42.9%). CONCLUSION: Compared with conventional observations, eye-tracking offered additional helpful insights and provided an in-depth analysis of gaze patterns during the recording of hand hygiene compliance in the intensive care unit.

[Acidosis without marked hyperglycemia : Euglycemic diabetic ketoacidosis associated with SGLT2-Inhibitors]. / Wenn der Patient sauer aber nicht süß ist : Die euglykämische diabetische Ketoacidose unter SGLT2-Inhibitoren.

Sodium-glucose cotransporter 2 (SGLT2) inhibitors are new antidiabetic drugs that regulate blood glucose levels by increasing urinary glucose excretion. In May 2015, the U.S. Food and Drug Administration (FDA) issued a warning that SGLT2 inhibitors may lead to ketoacidosis. In this report, we describe a case of life-threatening euglycemic ketoacidosis associated with SGLT2 inhibition and evaluate possible mechanisms and triggers.

Pulse intravenous cyclophosphamide therapy in pemphigus.

BACKGROUND: Adjuvant therapy is commonly used in pemphigus to mitigate the high morbidity and mortality associated with the use of corticosteroids and improve disease control. However, these adjuvant agents are not without adverse effects of their own, including an increased risk of malignancy with the use of oral immunosuppressives. Intravenous pulse cyclophosphamide, which may be more efficacious and less toxic than oral immunosuppressives, has been used successfully in the treatment of pemphigus. OBJECTIVE: To review 9 patients with severe or previously recalcitrant pemphigus who were treated with intravenous pulse cyclophosphamide therapy. RESULTS: Six of the 9 patients responded to therapy, with 2 patients achieving remission from skin lesions. Five patients were able to decrease their daily dose of prednisone, and 1 was able to discontinue the use of prednisone completely. Most patients experienced minimal or no adverse effects. CONCLUSIONS: Intravenous pulse cyclophosphamide may be an alternative treatment option in patients with pemphigus recalcitrant to standard therapy. The decreased cumulative dose of cyclophosphamide observed with monthly pulse doses may reduce the incidence of secondary malignancies when compared with continuous oral therapy. Controlled trials are needed to further evaluate the efficacy of this mode of therapy.
