[Bedside-teaching on dementia and delirium: Development, implementation, and evaluation in an acute care hospital]. / Bedside-Teaching zum Thema Demenz und Delir.

Bedside-teaching on dementia and delirium: Development, implementation, and evaluation in an acute care hospital Abstract: Background: Demographic change and the accompanying increase in people with dementia and delirium in acute care hospitals pose growing challenges for nurses in acute care wards. Objective: Pilot implementation and evaluation of knowledge gain and implementation of previously defined critical behaviors. Method: Implementation of the training by APNs. Parallel evaluation of the training along the New World Kirkpatrick model using questionnaires and non-participant observation. Analysis of the data using descriptive statistics. Results: The training itself was well evaluated by the participants. It showed an increase in knowledge of the participants in the main topic categories. The targeted critical behaviors were implemented for the most part. There are deficiencies in the mapping of interventions in the nursing care process. Conclusion: The training concept is suitable to give nurses confidence in dealing with people with dementia and delirium. Continuous support in practice is needed to maintain the interventions in the long term and sustainably in everyday life.

[Experience of nurses using the COVID-19 Early Warning Score in the care of COVID-19 patients: A qualitative study]. / Erfahrungen von Pflegekräften mit dem COVID-19 Early Warning Score in der akutstationären Versorgung.

Experience of nurses using the COVID-19 Early Warning Score in the care of COVID-19 patients: A qualitative study Abstract: Background: In all phases of the COVID-19 disease, patients are at risk of acute deterioration. In order to identify patients at risk at an early stage, the COVID-19-EWS Salzburg was implemented in April 2020 at the University Hospital Salzburg. So far, the applicability, practicability and relevance of the EWS for acute inpatient COVID-19 care are unknown. Aim: The aim of this qualitative study was to describe the relevance and practicability of the COVID-19-EWS Salzburg as a risk assessment tool for acute inpatient COVID-19 care, based on the experiences of the nursing staff. Methods: Nine semi-structured expert interviews were conducted with the nursing staff of the COVID-19 acute care unit. The data were analysed by qualitative content analysis. Results: Nurses described the EWS as relevant to practice because the score facilitates decision-making, increases patient safety, and enhances interprofessional communication. Both the Early Warning Score (EWS) and experience in caring for COVID-19 patients were found to be relevant for decision-making in the context of managing clinical deterioration. The score provided a sense of security in the care of COVID-19 patients, particularly to new and inexperienced nurses. Conclusion: The participating nurses describe the COVID-19-EWS Salzburg as a useful and practical risk assessment instrument, complementing clinical judgment. A need for adaptation concerning the parameters oxygen saturation and oxygen requirement was identified.

[Clinical study PEPCA : The effect of standardized preoperative patient education for patient-controlled regional analgesia on postoperative pain]. / Klinische Studie PEPCA : Der Effekt standardisierter präoperativer Patientenedukation zu patientenkontrollierter Regionalanästhesie auf postoperative Schmerzen.

BACKGROUND: Patient-controlled analgesia (PCA) is a well-established form of postoperative pain management. One form of administration is patient-controlled regional analgesia (PCRA), where local anesthetics are administered via peripheral regional catheters; however, a prerequisite is that the patients are instructed on its use. A multitude of sources recommend that these instructions are given before surgery as preoperative training on pain management procedures has been shown to significantly reduce patients' postoperative pain and increase their well-being. OBJECTIVE: The aim was to assess the effect of guideline-assisted preoperative patient education for PCRA on postoperative pain in patients undergoing orthopedic surgery compared to unstructured postoperative standard instructions. MATERIAL AND METHODS: A controlled study with two randomized samples and a postinterventional survey was conducted. Overall, 73 patients with PCRA catheters for orthopedic surgery were enrolled in the study. The 37 participants in the interventional group (IG) received guideline-based structured instructions on PCRA use as well as a handout immediately before the surgical intervention. The 36 patients in the control group (CG) received postoperative instructions in the anesthesia recovery room. Pain was documented according to the numerical rating scale (NRS) at 2h (t1), 6h (t2), and 24h (t3) after surgery. RESULTS: There were no statistically significant differences in the average pain scores between the two groups; however, there were lower mean pain scores in the IG at t1 and t3. CONCLUSION: A significant reduction of pain in the IG could not be shown. Further studies concerning this topic with larger samples and adapted points in time are recommended.

The Influence of Human Factors Training in Air Rescue Service on Patient Safety in Hospitals: Results of an Online Survey.

Background: Air rescue crew members work equally in aviation and medicine, and thus occupy an important interface between the two work environments of aviation and medicine. The aim of this study was to obtain responses from participants to a validated online-based questionnaire regarding whether hospitals may benefit from the commitment of a medical hospital staff which is also professionally involved in the aviation system as emergency physicians and Helicopter Emergency Medical Services Technical Crew Members (HEMS TC). Furthermore, it focused on the question of whether the skills acquired through Crew Resource Management (CRM) training in the air rescue service might also be used in the ground-based rescue service and, if so, whether they may have a positive effect. Methods: Medical air rescue staff of 37 German air rescue stations was included. Between 27 November 2020 and 03 March 2021, 253 out of 621 employees (response rate: 40.7%) participated voluntarily in a validated anonymized online survey. A quantitative test procedure was performed using the modified questionnaire on teamwork and patient safety (German version). Results: The examination and interpretation of the internal consistency (Cronbach's alpha) resulted in the following reliabilities: Factor I (Cooperation): α = 0.707 (good); Factor II (Human factors): α = 0.853 (very good); Factor III (Communication): α = 0.657 (acceptable); and Factor IV (Safety): α = 0.620 (acceptable). Factor analysis explained 53.1% of the variance. Conclusions: The medical clinicians participating in this online survey believed that the skills they learned in human factors training such as CRM are helpful in their daily routine work in hospitals or other medical facilities, as well as in their ground-based rescue service activities. These findings may result in the recommendation to make CRM available on a regular to the medical staff in all medical facilities and also to ground-based rescue service staff aiming to increase patient safety and employee satisfaction.

Prevalence for delirium in stroke patients: A prospective controlled study.

BACKGROUND AND PURPOSE: This study investigates the prevalence of delirium in acute stroke patients on a primary stroke unit (SU) analyzing associated risk factors and clinical outcomes. METHOD: Prospective, 4-month observational study from 2015 to 2016 on patients aged ≥18 years with stroke at a German university hospital's SU. The presence of delirium as first outcome was rated at three times daily using the Confusion Assessment Method (CAM). Secondary outcome measures were duration of delirium, rehabilitation in SU, length of stay in SU and hospital, complications, and mortality. Significant risk factors were used to conduct a confounder-matched case-control analysis. RESULTS: 309 patients were included. The overall prevalence of delirium was 10.7% (33 patients) mostly on the first and second hospital day. Duration of delirium on SU was in median 1.0 day (Interquartile range: 0.3-2 days). In 39.4% of patients delirium was present in a short time interval (≤8 hr) and in 24% of patients delirium was diagnosed during nightshifts exclusively. Significant risk factors for delirium were dementia, age ≥72 years, severe neurological disability on admission, and increased C-reactive protein on admission. The case-control analysis showed that delirious patients had more complications and a trend toward a worse rehabilitation. CONCLUSIONS: These results underline the importance of delirium screening in stroke patients specifically during the night. Since even short delirious episodes are associated with more complications and increased disability, future studies are needed to find delirium prevention strategies.

Complications related to early mobilization of mechanically ventilated patients on Intensive Care Units.

AIMS AND OBJECTIVES: To compare international literature on the detection of complications associated with early mobilization of mechanically ventilated patients in intensive care units (ICUs). BACKGROUND: Early mobilization of mechanically ventilated ICU patients is considered to be a more beneficial approach to treatment in intensive care; however, it remains unclear how safe this approach is and what complications to expect. SEARCH STRATEGIES: A systematic literature research in English and German was conducted in June 2013 in the databases Pubmed, CINAHL, Cochrane library and MedPilot without limiting by year of publication. References of the included studies were screened and supplemented by manual search. INCLUSION AND EXCLUSION CRITERIA: Inclusion criteria were studies about mechanically ventilated adult patients on ICU, who were mobilized and reported complications. Excluded were studies that (a) did not differentiate between non-ventilated and ventilated patients, (b) did not report complications and (c) focused on in-bed mobilization. CONCLUSIONS: Of 952 titles, 16 articles fit the criteria including 3 reviews and 13 clinical trials. The percentage of complications in clinical trials ranged between 0% and 16%. In total, 453 patients were mobilized 3613 times (up to walking with ventilation) with a complication mean rate of 3·9% (n = 144) using the inherent safety limits. No fall, cardiac arrest, or death was reported. Most complications were pulmonary, followed by haemodynamic ones. Serious complications that led to further consequences were observed in 0·3% (n = 10) of all mobilizations. The clinical studies have been carried out in trained, interdisciplinary teams with most of them using adapted algorithms for safety. RELEVANCE TO CLINICAL PRACTICE: Despite a low complication rate, a frame for safety during early mobilization including team training and adapted criteria is recommended.

The occurrence of acute postoperative confusion in patients after cardiac surgery.

This study quantified the occurrence of acute confusion in cardiac surgery patients at three German hospitals. A total of 867 patients, 22-91 years old, were examined each nursing shift postoperatively for 5 days for the presence of acute confusion using a modified version of the Glasgow Coma Scale and Confusion Rating Scale. The night shifts and the third postoperative day showed the most frequent periods of occurrence. Confusional state was noted in patients ranging from 10.5% for patients aged <70, to 40.7% for patients >80 years of age. Those found at increased risk were patients of increasing age and coexisting disease. Targeted nursing interventions for patients at increased risk of acute confusion may decrease this complication.

[Acute postoperative confusion in heart surgery patients]. / Akute postoperative Verwirrtheit kardiochirurgischer Patienten.

Unlike other countries, Germany does not have data about the incidence of acute confusion following heart surgery. However, the occurrence of acute confusion does extend the hospitalization length by up to 13 days. Thus, this phenomenon is of high relevance for the health profession. This incidence study was performed with the goal to obtain exact information on the incidence rate of acute postoperative confusion after heart surgery (bypass and valve operations) through a multi-center evaluation. The data evaluation took place in the form of a convenient sample survey in three different German clinics specialized in heart surgery. The observation period lasted from the day of surgery up to the fifth postoperative day. In the context of this prospective cohort study, suitable study participants were all patients aged 18 or older who underwent heart surgery between February 1st and April 30th, 2000. At the end, 860 patients were included in the study. A total of 152 patients showed symptoms of acute confusion, meaning a total incidence of 17.4% (confidence interval 14-20%). The occurrence of this phenomenon was not symmetrical. A wide-spread occurrence could be observed particularly at night. Patients aged 81-91 were mainly affected, with an incidence of confusion of 43.5% in this group. The results confirm the clinical importance of this issue and require interdisciplinary approaches for solution.
