Secondary outcome measures were the proportion of (i) catheter days without appropriate indication and (ii) patients discharged with a catheter.There was a reduction in the proportion of inpatient days with a catheter, from 44% to 41% (P = 0.006). There was also a reduction in the proportion of catheter days without appropriate indication (P < 0.001) and patients discharged with a catheter (P = 0.029). The majority of catheters were inserted outside the study wards.A short educational intervention was feasible and resulted in significant practice improvements in catheter usage but no reduction of CAUTIs. Other measures than CAUTI may be more sensitive to detecting important practice changes.Icelandic Nurses' Association Research Fund

The challenge of caring for patients in pain: from the nurse's perspective
To access publisher full text version of this article. Please click on the hyperlink in Additional Links fieldAIM: To increase understanding of what it is like for nurses to care for patients in pain. BACKGROUND: Hospitalised patients are still suffering from pain despite increased knowledge, new technology and a wealth of research. Since nurses are key figures in successful pain management and research findings indicate that caring for suffering patients is a stressful and demanding experience where conflict often arises in nurses' relations with patients and doctors, it may be fruitful to study nurses' experience of caring for patients in pain to increase understanding of the above problem. DESIGN: A phenomenological study involved 20 dialogues with 10 experienced nurses. RESULTS: The findings indicate that caring for a patient in pain is a 'challenging journey' for the nurse. The nurse seems to have a 'strong motivation to ease the pain' through moral obligation, knowledge, personal experience and conviction. The main challenges that face the nurse are 'reading the patient', 'dealing with inner conflict of moral dilemmas', 'dealing with gatekeepers' (physicians) and 'organisational hindrances'. Depending upon the outcome, pain management can have positive or negative effects on the patient and the nurse. CONCLUSIONS: Nurses need various coexisting patterns of knowledge, as well as a favourable organisational environment, if they are to be capable of performing in accord with their moral and professional obligations regarding pain relief. Nurses' knowledge in this respect may hitherto have been too narrowly defined. RELEVANCE TO CLINICAL PRACTICE: The findings can stimulate nurses to reflect critically on their current pain management practice. By identifying their strengths as well as their limitations, they can improve their knowledge and performance on their own, or else request more education, training and support. Since nurses' clinical decisions are constantly moulded and stimulated by multiple patterns of knowledge, educators in pain management should focus not only on theoretical but also on personal and ethical knowledge
Perceptions about traditional and novel methods to learn about post-operative pain management : - a qualitative study.
Aim: To explore the perceptions of surgical patients about traditional and novel methods to learn about post-operative pain management.Background: Patient education is an important part of post-operative care. Contemporary technology offers new ways for patients to learn about self-care, although face-to-face discussions and brochures are the most common methods of delivering education in nursing practice.Design: A qualitative design with a vignette and semi-structured interviews used for data collection.Methods: A purposeful sample of 13 post-surgical patients, who had been discharged from hospital, was recruited during 2013 - 2014. The patients were given a vignette about anticipated hospital discharge after surgery with four different options for communication (face-to-face, brochure, website, serious game) to learn about post-operative pain management. They were asked to rank their preferred method of learning and thereafter to reflect on their choices. Data were analysed using an inductive content analysis approach.Findings: Patients preferred face-to-face education with a nurse, followed by brochures and websites, while games were least preferred. Two categories, each with two sub-categories, emerged from the data. These conceptualised the factors affecting patients' perceptions: 1) 'Trusting the source', sub-categorised into 'Being familiar with the method' and 'Having own prejudgments'; and 2) 'Being motivated to learn' sub-categorised into 'Managing an impaired cognition' and 'Aspiring for increased knowledge'.Conclusion: In order to implement successfully novel educational methods into post-operative care, healthcare professionals need to be aware of the factors influencing patients' perceptions abouthow to learn, such as trust and motivation.Funding agencies: Landspitali University Hospital Research Fund; Icelandic Nurses Association Research Fund</p

Automated Mechanism Generation Using Linear Scaling Relationships and Sensitivity Analyses Applied to Catalytic Partial Oxidation of Methane
Kinetic parameters for surface reactions can be predicted using a combination of DFT calculations, scaling relations, and machine learning algorithms; however, construction of microkinetic models still requires a knowledge of all the possible, or at least reasonable, reaction pathways. The recently developed Reaction Mechanism Generator (RMG) for heterogeneous catalysis, now included in RMG version 3.0, is built upon well-established, open-source software that can provide detailed reaction mechanisms from user-supplied initial conditions without making a priori assumptions. RMG is now able to estimate adsorbate thermochemistry and construct detailed microkinetic models on a range of hypothetical metal surfaces using linear scaling relationships. These relationships are a simple, computationally efficient way to estimate adsorption energies by scaling the energy of a calculated surface species on one metal to any other metal. By conducting simulations with sensitivity analyses, users can not only determine the rate limiting step on each surface by plotting a "volcano surface" for the degree of rate control of each reaction as a function of elemental binding energies, but also screen novel catalysts for desirable properties. We investigated the catalytic partial oxidation of methane to demonstrate the utility of this new tool and determined that an inlet gas C/O ratio of 0.8 on a catalyst with carbon and oxygen binding energies of -6.75 eV and -5.0 eV, respectively, yields the highest amount of synthesis gas. Sensitivity analyses show that while the dissociative adsorption of O2 has the highest degree of rate control, the interactions between individual reactions and reactor conditions are complex, which result in a dynamic rate-limiting step across differing metals.</div
Development, usability, and efficacy of a serious game to help patients learn about pain management after surgery: an evaluation study
Background: Postoperative pain is a persistent problem after surgery and can delay recovery and develop into chronic pain. Better patient education has been proposed to improve pain management of patients. Serious games have not been previously developed to help patients to learn how to manage their postoperative pain. Objective: The aim of this study was to describe the development of a computer-based game for surgical patients to learn about postoperative pain management and to evaluate the usability, user experience, and efficacy of the game. Methods: A computer game was developed by an interdisciplinary team following a structured approach. The usability, user experience, and efficacy of the game were evaluated using self-reported questionnaires (AttrakDiff2, Postoperative Pain Management Game Survey, Patient Knowledge About Postoperative Pain Management questionnaire), semi-structured interviews, and direct observation in one session with 20 participants recruited from the general public via Facebook (mean age 48 [SD 14]; 11 women). Adjusted Barriers Questionnaire II and 3 questions on health literacy were used to collect background information. Results: Theories of self-care and adult learning, evidence for the educational needs of patients about pain management, and principles of gamification were used to develop the computer game. Ease of use and usefulness received a median score between 2.00 (IQR 1.00) and 5.00 (IQR 2.00) (possible scores 0-5; IQR, interquartile range), and ease of use was further confirmed by observation. Participants expressed satisfaction with this novel method of learning, despite some technological challenges. The attributes of the game, measured with AttrakDiff2, received a median score above 0 in all dimensions; highest for attraction (median 1.43, IQR 0.93) followed by pragmatic quality (median 1.31, IQR 1.04), hedonic quality interaction (median 1.00, IQR 1.04), and hedonic quality stimulation (median 0.57, IQR 0.68). Knowledge of pain medication and pain management strategies improved after playing the game (P=.001). Conclusions: A computer game can be an efficient method of learning about pain management; it has the potential to improve knowledge and is appreciated by users. To assess the game’s usability and efficacy in the context of preparation for surgery, an evaluation with a larger sample, including surgical patients and older people, is required
Quantifying the Impact of Parametric Uncertainty on Automatic Mechanism Generation for CO2 Hydrogenation on Ni(111)
Automatic mechanism generation is used to determine mechanisms for the CO2
hydrogenation on Ni(111) in a two-stage process, while considering the uncertainty
in energetic parameters systematically. In a coarse stage, all the possible chemistry is
explored with gas-phase products down to the ppb level, while a refined stage discovers
the core methanation submechanism. 5,000 unique mechanisms were generated, which
contain minor perturbations in all parameters. Global uncertainty assessment, global
sensitivity analysis, and degree of rate control analysis are performed to study the effect
1
of this parametric uncertainty on the microkinetic model predictions. Comparison of
the model predictions with experimental data on a Ni/SiO2
catalyst find a feasible set
of microkinetic mechanisms that are in quantitative agreement with the measured data,
without relying on explicit parameter optimization. Global uncertainty and sensitivity
analyses provide tools to determine the pathways and key factors that control the
methanation activity within the parameter space. Together, these methods reveal that
the degree of rate control approach can be misleading if parametric uncertainty is not
considered. The procedure of considering uncertainties in the automated mechanism
generation is not unique to CO2 methanation and can be easily extended to other
challenging heterogeneously catalyzed reactions<br /
Nationwide Incidence and Outcomes of Patients With Coronavirus Disease 2019 Requiring Intensive Care in Iceland.
To access publisher's full text version of this article click on the hyperlink belowObjectives: To determine the nationwide demographics and hospital mortality of patients with severe acute respiratory syndrome coronavirus 2 infection requiring admission to the ICU for coronavirus disease 2019 in Iceland.
Design: Prospective observational study.
Setting: All ICUs in Iceland (Landspitali University Hospital and Akureyri Regional Hospital).
Patients: All patients admitted to the ICU for management of coronavirus disease 2019 between March 14, 2020, and April 13, 2020, with follow-up through May 5, 2020.
Interventions: None.
Measurements and main results: A total of 27 patients were admitted to the ICU for coronavirus disease 2019 out of 1,788 severe acute respiratory syndrome coronavirus 2 positive cases, rendering an overall admission ratio of 1.5% (95% CI, 1.0-2.2%). The population rate of ICU admission for coronavirus disease 2019 was 7.4 (95% CI, 4.9-10.8) admissions per 100,000 individuals. The hospital mortality of patients admitted to the ICU was 15% (95% CI, 4-34%), and the mortality of patients receiving mechanical ventilation was 19% (95% CI, 4-46%).
Conclusions: We report a lower overall ratio of ICU admissions for coronavirus disease 2019 among severe acute respiratory syndrome coronavirus 2 positive patients and a lower hospital mortality for patients treated in the ICU for coronavirus disease 2019 compared with initial reports from Italy and China. Our results could be explained by the early adoption of widespread testing and a successful national response to the pandemic
