[Development and content validity of a questionnaire to assess knowledge about delirium]. / Weiterentwicklung und Inhaltsvalidierung eines Fragebogens zur Erfassung des Wissens über das Delir.

BACKGROUND: Delirium is a neuropsychiatric syndrome that can have serious consequences and is often overlooked by healthcare professionals. The level of knowledge about delirium is often insufficient among nursing and medical staff. At the current time there is no suitable questionnaire to record the level of knowledge in German-speaking countries. AIM: Development of a questionnaire and evaluation of content validity. METHODS: Following a literature search to identify current best practice, several questionnaires were identified. An already published questionnaire with the dimensions of basic knowledge of delirium and risk factors has been translated, adapted and extended by the dimension of nonpharmacological delirium prevention. Delirium experts assessed the relevance of the questionnaire items in two rounds of reviews. Content validity was calculated using the Content Validity Index (CVI) at item (I-CVI) and scale (S-CVI) level. Additionally, the modified Kappa (k*) was calculated using a lower 95% confidence interval (CI). RESULTS: The original 30-item questionnaire was expanded to include 18 delirium prevention items. After the first round of scoring 30 out of 48 items showed good to excellent I­CVI scores. Considering the comments, 6 items were discarded and 12 were adapted in terms of language and content. In the final version of the questionnaire 41 items with excellent scores remained. The total scale score increased from 0.88 in the first version to 1.0 in the final version. Nurses were identified as the target group, potentially also therapists and medical personnel. CONCLUSION: The delirium knowledge questionnaire is content-valid.

Delirium on stroke units: a prospective, multicentric quality-improvement project.

BACKGROUND: Post-stroke delirium (POD) in patients on stroke units (SU) is associated with an increased risk for complications and poorer clinical outcome. The objective was to reduce the severity of POD by implementing an interprofessional delirium-management. METHODS: Multicentric quality-improvement project on five SU implementing a delirium-management with pre/post-comparison. Primary outcome was severity of POD, assessed with the Nursing Delirium Screening Scale (Nu-DESC). Secondary outcome parameters were POD incidence, duration, modified Rankin Scale (mRS), length of stay in SU and hospital, mortality, and others. RESULTS: Out of a total of 799 patients, 59.4% (n = 475) could be included with 9.5% (n = 45) being delirious. Implementation of a delirium-management led to reduced POD severity; Nu-DESC median: pre: 3.5 (interquartile range 2.6-4.7) vs. post 3.0 (2.2-4.0), albeit not significant (p = 0.154). Other outcome parameters were not meaningful different. In the post-period, delirium-management could be delivered to 75% (n = 18) of delirious patients, and only 24 (53.3%) of delirious patients required pharmacological treatments. Patients with a more severe stroke and POD remained on their disability levels, compared to similar affected, non-delirious patients who improved. CONCLUSIONS: Implementation of delirium-management on SU is feasible and can be delivered to most patients, but with limited effects. Nursing interventions as first choice could be delivered to the majority of patients, and only the half required pharmacological treatments. Delirium-management may lead to reduced severity of POD but had only partial effects on duration of POD or length of stay. POD hampers rehabilitation, especially in patients with more severe stroke.

[Integrating academic nurses in German university hospitals: a follow-up survey]. / Einbindung von Pflegefachpersonen mit Hochschulabschlüssen an deutschen Universitätskliniken: ein Follow-up-Survey.

INTRODUCTION: The effective integration of professional nursing staff with university training into care processes is associated internationally with better patient outcomes. In Germany, there is a current lack of reliable figures on graduates and their areas of responsibility. Therefore, the aim of this follow-up survey, designed as a repetition of a previous one, was to ascertain the number of nurses with a Bachelor's or Master's degree involved in direct patient care at university medical centers. METHOD: In a cross-sectional study, chief nursing officers in university medical centers were asked to quote the number of professional nurses with a university degree (Bachelor, Master, Doctorate). Additional questions focused on their tasks and responsibilities and the measures undertaken to facilitate their integration into the organization. The data were analyzed using descriptive statistics. RESULTS: In total, n=29 valid questionnaires from 35 university medical centers were included in the analysis, resulting in a response rate of 82.85%. For a total of 18 centers, the number of university-qualified nurses had increased by n=786 between 2015 (n=593) and 2018 (n=1,379). The overall percentage of nurses with a university degree working at a university medical center in the study was 3.16% (SD=1.66; min - max=1.09 - 6.69; Q1 - Q3=1.49 - 4.04; 95% CI 2.30 to 3.95). In direct patient care, the quota was 2.11% (SD=1.40; min - max=0.47 - 5.42; Q1 - Q3=0.87 - 3.16; 95% CI 1.36 to 2.76). The main focus of their duties was on standard care and patient education (graduates with a Bachelor's degree), evidence-based nursing practice development (Master's degree) and research activities (doctoral degree). DISCUSSION: Compared to 2015, the proportion of professional nursing staff with university training has increased but remains at a very low level. These nurses perform relevant clinical tasks and are involved in the development of good practice. However, there is a need for better competence-based differentiation.

[Evidence-based non-pharmacological delirium prevention on general wards - A systematic literature review]. / Evidenzbasierte nicht-pharmakologische Delirprävention im allgemeinstationären Bereich ­ Eine systematische Übersichtsarbeit.

BACKGROUND: Delirium is a disturbance of attention and consciousness and a serious complication, especially in older hospitalized patients. For non-pharmacological delirium prevention, mainly so-called multicomponent programmes are described, which have to be adapted to the individual risk profile. The aim of this systematic review was to summarize the current status of the available evidence on non-pharmacological delirium prevention in general wards. METHOD: The databases MEDLINE via Pubmed, CINAHL, EMBASE, PsycINFO and Cochrane Library were searched for the period from 1990 to November 2018; the methodological quality of the systematic reviews and meta-analyses was evaluated with AMSTAR 2. In order to reflect the broad spectrum of delirium prevention, international guidelines were included in the systematic review. RESULTS: A total of 77 titles were read in full text, nine reviews and six guidelines were included in the analysis. Eight meta-analyses demonstrated that non-pharmacological multicomponent programmes for delirium prevention reduce the incidence of delirium compared to standard care (RR 0.65 to 0.73; OR 0.47 to 0.64, with varying methodological quality). The effect size was similar in the surgical (RR 0.63 to 0.71; OR 0.64) and non-surgical (RR 0.65 to 0.73; OR 0.47) general ward setting. The multicomponent programmes for delirium prevention each consisted of a different number of interventions. In addition to twelve person-related interventions, e. g. promotion of orientation, mobility, day-night rhythm, environmental adjustments and staff training programmes, were considered. CONCLUSION: Non-pharmacological multicomponent programmes for the prevention of delirium in general wards effectively reduce the incidence of delirium and must be adapted to the individual risk factors of each patient.

Validation of two nurse-based screening tools for delirium in elderly patients in general medical wards.

BACKGROUND: Delirium is an acute disturbance characterized by fluctuating symptoms related to attention, awareness and recognition. Especially for elderly patients, delirium is frequently associated with high hospital costs and resource consumption, worse functional deterioration and increased mortality rates. Early recognition of risk factors and delirium symptoms enables medical staff to prevent or treat negative effects. Most studies examining screening instruments for delirium were conducted in intensive care units and surgical wards, and rarely in general medical wards. The aim of the study is to validate the Nursing Delirium Screening Scale (Nu-DESC) and the Delirium Observation Screening Scale (DOS) in general medical wards in a German tertiary care hospital, considering predisposing delirium risk factors in patients aged 65 and older. METHODS: The prospective observational study including 698 patients was conducted between May and August 2018 in two neurological and one cardiology ward. During their shifts, trained nurses assessed all patients aged 65 or older for delirium symptoms using the Nu-DESC and the DOS. Delirium was diagnosed according to the DSM-5 criteria by neurologists. Patient characteristics and predisposing risk factors were obtained from the digital patient management system. Descriptive and bivariate statistics were computed. RESULTS: The study determined an overall delirium occurrence rate of 9.0%. Regarding the DOS, sensitivity was 0.94, specificity 0.86, PPV 0.40 NPV 0.99 and regarding the Nu-DESC, sensitivity was 0.98, specificity 0.87, PPV 0.43, NPV 1.00. Several predisposing risk factors increased the probability of delirium: pressure ulcer risk OR: 17.3; falls risk OR: 14.0; immobility OR: 12.7; dementia OR: 5.38. CONCLUSIONS: Both screening instruments provided high accuracy for delirium detection in general medical wards. The Nu-DESC proved to be an efficient delirium screening tool that can be integrated into routine patient care. According to the study results, pressure ulcer risk, falls risk, and immobility were risk factors triggering delirium in most cases. Impaired mobility, as common risk factor of the before mentioned risks, is well known to be preventable through physical activity programmes.

Educational strategies and challenges in peritoneal dialysis: a qualitative study of renal nurses' experiences.

AIMS AND OBJECTIVES: The aim of the study was to explore renal nurses' experiences, strategies and challenges with regard to the patient education process in peritoneal dialysis. BACKGROUND: Patient education in peritoneal dialysis is essential to developing a successful home-based peritoneal dialysis program. In this area research is scarce and there is a particular lack of focus on the perspective of the renal nurse. DESIGN: Qualitative design formed by thematic qualitative text analysis. METHODS: Five group interviews (n = 20) were used to explore the challenges peritoneal dialysis nurses face and the training strategies they use. The interviews were analyzed with thematic qualitative content analysis using deductive and inductive subcategory application. RESULTS: The findings revealed the education barriers perceived by nurses that patients may face. They also showed that using assessment tools is important in peritoneal dialysis patient education, as is developing strategies to promote patient self-management. There is a need for a deeper understanding of affective learning objectives, and existing teaching activities and materials should be revised to incorporate the patient's perspective. Patients usually begin having questions about peritoneal dialysis when they return home and are described as feeling overwhelmed. Adapting existing conditions is considered a major challenge for patients and nurses. CONCLUSIONS: The results provided useful insights into the best approaches to educating peritoneal dialysis patients and served to raise awareness of challenges experienced by renal nurses. Findings underline the need for nosogogy - an approach of teaching adults (andragogy) with a chronic disease. Flexibility and cooperation are competencies that renal nurses must possess. RELEVANCE TO CLINICAL PRACTICE: Still psychomotor skills dominate peritoneal dialysis patient training, there is a need of both a deeper understanding of affective learning objectives and the accurate use of (self-)assessment tools, particularly for health literacy.

Educational interventions in peritoneal dialysis: a narrative review of the literature.

OBJECTIVES: To review the current literature on educational interventions used in peritoneal dialysis (PD). Educational interventions have become increasingly relevant because they play a key role in helping individuals to actively participate in their therapy and to manage their chronic condition. The paper will focus on two areas: (a) educational interventions for individuals living with PD and (b) educational interventions for PD nurses. DESIGN: A narrative review of primary research. DATA SOURCES: Electronic searches of the MEDLINE, CINAHL, EMBASE, ERIC and Cochrane Library (2006-2013) databases were undertaken using terms such as peritoneal dialysis, insertive training, curriculum, nursing education, train the trainer, coach the coach, tutor the tutor, and patient education were used. All studies were reviewed by two researchers. REVIEW METHODS: Titles and abstracts of 555 studies were screened and read. Full text articles retrieved were further screened against the inclusion and exclusion criteria. Relevant data on the educational interventions for people receiving PD and nurse training programs were extracted and synthesized narratively. RESULTS: Eighteen articles met the inclusion criteria. Most of them focused on educational intervention programs for people undergoing PD. Findings on the link between the PD trainer's background and peritonitis rates among individuals undergoing PD are inconsistent. PD learners should be taught self-management skills as well as technical skills. They might also benefit from receiving decision-making aids. Older people, people with co-morbidities and people with low educational status need more time to acquire self-care skills and are more likely to develop peritonitis. Home visits have the potential to improve learning outcomes. Re-training needs should be assessed and fulfilled as appropriate. Case and disease management programs have been shown to have positive outcomes for individuals receiving PD. CONCLUSIONS: Educational interventions for PD remain an under-researched area, despite the potential they have to make this type of therapy more successful. Further research on education and training for people receiving PD and for PD nurses is needed. In the meantime, educational interventions used for other chronic conditions could provide guidance.

Evaluating students' perception of their clinical placements - testing the clinical learning environment and supervision and nurse teacher scale (CLES + T scale) in Germany.

Clinical nursing education in Germany has not received attention in nursing science and practice for a long time, as it often seems to be a more or less "formalized appendix" of nursing education. Several development projects of clinical education taking place are mainly focused on the qualification of clinical preceptors. However, the clinical context and its influence on learning processes have still not been sufficiently investigated. The aim of this study was the testing of a German version of the clinical learning environment and supervision and nurse teacher scale (CLES + T scale). The sample of the pilot study consists of first-, second- and third-year student nurses (n=240) of a university nursing school from January to March 2011. Psychometric testing of the instrument is carried out by selected methods of classical testing theories using SPPS 19. The results show transferability of all subcategories of the CLES + T scale in the non-academic nursing education system of a university hospital in Germany, without the teacher scale. The strongest factor is "supervisory relationship". The German version of the CLES + T scale may help to evaluate and compare traditional and new models in clinical nursing education.
