Preoperative anxiety after face-to-face patient assessment versus preanaesthesia telemedicine (PANTEM) in adults: a randomised clinical trial.

Preanaesthesia consultation is performed to assess and optimise patient-specific risk factors before surgery, to inform patients about anaesthesia techniques and to obtain consent. Aside from face-to-face visits, telephone consultation is increasingly being used clinically. Concentration on the content and avoidance of confounding factors could lead to improved patient preparation. We hypothesised that patients receiving a telemedical intervention have less anxiety. Patients scheduled for elective surgery were randomised into two groups according to the consultation performed face-to-face (FTF) or via telephone (TEL). Before consultation (< 48 h) and 1-2 h prior to surgery, both groups had to fill in the State-Trait Anxiety Inventory (STAI). A total of 271 patients were randomised and 130 were analysed. There were no significant intergroup differences in mean state anxiety (STAI-S) before and after the intervention. Patients' positive feedback on telemedical consultation urges future studies on its effect on satisfaction and quality of life.

[Preoperative risk clarification and anesthesia disclosure by telephone conversation]. / Präoperative Risikoabklärung und Anästhesieaufklärung mittels Telefonvisite.

BACKGROUND: Preoperative risk stratification, patient optimization and anesthesia disclosure are mostly carried out in the preanesthesia outpatient department in a direct conversation between physician and patient. The aim of this article is a description of the preanesthesia telephone contact as an alternative disclosure and clarification option for the clinical practice. METHODS: After clarification of data protection and medicolegal aspects, experiences with providing information via telephone in a single center were gathered. RESULTS: Initially, before spinal operations pain patients with unreasonably long access routes to the preanesthesia outpatient department received clarification and disclosure via the telephone. Due to the effectiveness and the lack of medical and processual complications, after 1 year the offer of a telephone conversation was extended to all patients. In the meantime, 47% of preanesthesia conversations are now carried out by telephone. Factors relevant for success are the consent of the patient to a telephone conversation, a multimedia patient education before the telephone conversation, competence of the anesthetist in communication, documentation and a clearly defined description of the process including changeover to the direct conversation. CONCLUSION: The preanesthesia telephone conversation is suitable as an alternative to the preanesthesia conversation in the outpatient department. High patient satisfaction results from the patient-oriented process, avoidance of transportation routes and the participative communication.

Renin-angiotensin system inhibitor discontinuation in COVID-19 did not modify systemic ACE2 in a randomized controlled trial.

Despite the similar clinical outcomes after renin-angiotensin system (RAS) inhibitor (RASi) continuation or withdrawal in COVID-19, the effects on angiotensin-converting enzyme 2 (ACE2) and RAS metabolites remain unclear. In a substudy of the randomized controlled Austrian Corona Virus Adaptive Clinical Trial (ACOVACT), patients with hypertension and COVID-19 were randomized 1:1 to either RASi continuation (n = 30) or switch to a non-RASi medication (n = 29). RAS metabolites were analyzed using a mixed linear regression model (n = 30). Time to a sustained clinical improvement was equal and ACE2 did not differ between the groups but increased over time in both. Overall ACE2 was higher with severe COVID-19. ACE-S and Ang II levels increased as expected with ACE inhibitor discontinuation. These data support the safety of RASi continuation in COVID-19, although RASi were frequently discontinued in our post hoc analysis. The study was not powered to draw definite conclusions on clinical outcomes using small sample sizes.

Rapid Detection of Bacterial and Fungal Pathogens Using the T2MR versus Blood Culture in Patients with Severe COVID-19.

A high rate of bacterial and fungal superinfections was reported in critically ill patients with COVID-19. However, diagnosis can be challenging. The aim of this study is to evaluate the sensitivity and the clinical utility of the point-of-care method T2 magnetic resonance (T2MR) with the gold standard: the blood culture. T2MR can potentially detect five different Candida species and six common bacteria (so-called "ESKAPE" pathogens including Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Acinet`obacter baumanii, Pseudomonas aeruginosa, and Enterococcus faecium). If superinfection was suspected in patients with COVID-19 admitted to the intensive care unit, blood culture and two panels of T2MR were performed. Eighty-five diagnostic bundles were performed in 60 patients in total. T2MR detected an ESKAPE pathogen in 9 out of 85 (10.6%) samples, compared to BC in 3 out of 85 (3.5%). A Candida species was detected in 7 of 85 (8.2%) samples of T2MR compared to 1 out of 85(1.2%) in blood culture. The mean time to positive test result in samples with concordant positive results was 4.5 h with T2MR and 52.5 h with blood culture. The additional use of T2MR enables a highly sensitive and rapid detection of ESKAPE and Candida pathogens. IMPORTANCE Coronavirus disease 2019 (COVID-19) has led to a high number of deaths since the beginning of the pandemic worldwide. One of the reasons is the high number of bacterial and fungal superinfections in patients suffering from critical disease. However, diagnosis is often challenging. In this study we could show that the additional use of the culture-independent method T2MR did not only show a much higher detection rate of bacterial and fungal pathogens but also a significantly shorter time until detection and therapy change compared to the gold standard: the blood culture. The implementation of T2MRin the care of patients with severe course of COVID-19 might lead to an earlier sufficient antimicrobial therapy and as a result lower mortality and less use of broad-spectrum unnecessary therapy reducing the risk of resistance development.

The Role of Bacterial and Fungal Superinfection in Critical COVID-19.

BACKGROUND: The range of reported rates of bacterial and fungal superinfections in patients with a severe course of COVID-19 is wide, suggesting a lack of standardised reporting. METHODS: The rates of bacterial and fungal superinfection were assessed using predefined criteria to differentiate between infection and contamination. RESULTS: Overall, 117 patients admitted to the Intensive Care Unit due to severe COVID-19 were included. Overall, 55% of patients developed a superinfection and 13.6% developed a fungal superinfection (5.9% candidemia and 7.7% CAPA). The rate of ventilator-associated pneumonia was 65.2%. If superinfection was detected, the length of hospital stay was significantly longer and the mortality was especially increased if candidemia was detected. An increased risk of superinfection was observed in patients with pre-existing diabetes mellitus or chronic heart failure. The presence of immunomodulating therapy did not seem to have an impact on the frequency of superinfections. CONCLUSION: Increased awareness of high superinfection rates, fungal infections in particular, in patients suffering from severe COVID-19 is necessary.
