Prediction Models for Prolonged Intensive Care Unit Stay After Cardiac Surgery Systematic Review and Validation Study

Background— Several models have been developed to predict prolonged stay in the intensive care unit (ICU) after cardiac surgery. However, no extensive quantitative validation of these models has yet been conducted. This study sought to identify and validate existing prediction models for prolonged ICU length of stay after cardiac surgery. Methods and Results— After a systematic review of the literature, the identified models were applied on a large registry database comprising 11 395 cardiac surgical interventions. The probabilities of prolonged ICU length of stay based on the models were compared with the actual outcome to assess the discrimination and calibration performance of the models. Literature review identified 20 models, of which 14 could be included. Of the 6 models for the general cardiac surgery population, the Parsonnet model showed the best discrimination (area under the receiver operating characteristic curve=0.75 [95% confidence interval, 0.73 to 0.76]), followed by the European system for cardiac operative risk evaluation (EuroSCORE) (0.71 [0.70 to 0.72]) and a model by Huijskes and colleagues (0.71 [0.70 to 0.73]). Most of the models showed good calibration. Conclusions— In this validation of prediction models for prolonged ICU length of stay, 2 widely implemented models (Parsonnet, EuroSCORE), although originally designed for prediction of mortality, were superior in identifying patients with prolonged ICU length of stay.

In-Hospital Risk Prediction for Post-stroke Depression Development and Validation of the Post-stroke Depression Prediction Scale

Background and Purpose— The timely detection of post-stroke depression is complicated by a decreasing length of hospital stay. Therefore, the Post-stroke Depression Prediction Scale was developed and validated. The Post-stroke Depression Prediction Scale is a clinical prediction model for the early identification of stroke patients at increased risk for post-stroke depression. Methods— The study included 410 consecutive stroke patients who were able to communicate adequately. Predictors were collected within the first week after stroke. Between 6 to 8 weeks after stroke, major depressive disorder was diagnosed using the Composite International Diagnostic Interview. Multivariable logistic regression models were fitted. A bootstrap-backward selection process resulted in a reduced model. Performance of the model was expressed by discrimination, calibration, and accuracy. Results— The model included a medical history of depression or other psychiatric disorders, hypertension, angina pectoris, and the Barthel Index item dressing. The model had acceptable discrimination, based on an area under the receiver operating characteristic curve of 0.78 (0.72–0.85), and calibration (P value of the U-statistic, 0.96). Transforming the model to an easy-to-use risk-assessment table, the lowest risk category (sum score, <−10) showed a 2% risk of depression, which increased to 82% in the highest category (sum score, >21). Conclusions— The clinical prediction model enables clinicians to estimate the degree of the depression risk for an individual patient within the first week after stroke.

Competencies required for nursing telehealth activities: A Delphi-study

BACKGROUND Telehealth is viewed as a major strategy to address the increasing demand for care and a shrinking care professional population. However, most nurses are not trained or are insufficiently trained to use these technologies effectively. Therefore, the potential of telehealth fails to reach full utilization. A better understanding of nursing telehealth entrustable professional activities (NT-EPAs) and the required competencies can contribute to the development of nursing telehealth education. METHOD In a four-round Delphi-study, a panel of experts discussed which NT-EPAs are relevant for nurses and which competencies nurses need to possess to execute these activities effectively. The 51 experts, including nurses, nursing faculty, clients and technicians all familiar with telehealth, were asked to select items from a list of 52 competencies based on the literature and on a previous study. Additionally, the panelists could add competencies based on their experience in practice. The threshold used for consensus was set at 80%. RESULTS Consensus was achieved on the importance of fourteen NT-EPAs, requiring one or more of the following core competencies; coaching skills, the ability to combine clinical experience with telehealth, communication skills, clinical knowledge, ethical awareness, and a supportive attitude. Each NT-EPA requires a specific set of competencies (at least ten). In total, 52 competencies were identified as essential in telehealth. DISCUSSION/CONCLUSION Many competencies for telehealth, including clinical knowledge and communication skills, are not novel competencies. They are fundamental to nursing care as a whole and therefore are also indispensable for telehealth. Additionally, the fourteen NT-EPAs appeared to require additional subject specific competencies, such as the ability to put patients at ease when they feel insecure about using technology. The NT-EPAs and related competencies presented in this study can be used by nursing schools that are considering including or expanding telehealth education in their curriculum.

Preadmission interventions to prevent postoperative complications in older cardiac surgery patients: A systematic review

OBJECTIVE(S) The literature on postoperative complications in cardiac surgery patients shows high incidences of postoperative complications such as delirium, depression, pressure ulcer, infection, pulmonary complications and atrial fibrillation. These complications are associated with functional and cognitive decline and a decrease in the quality of life after discharge. Several studies attempted to prevent one or more postoperative complications by preoperative interventions. Here we provide a comprehensive overview of both single and multiple component preadmission interventions designed to prevent postoperative complications. METHODS We systematically reviewed the literature following the PRISMA statement guidelines. RESULTS Of 1335 initial citations, 31 were subjected to critical appraisal. Finally, 23 studies were included, of which we derived a list of interventions that can be applied in the preadmission period to effectively reduce postoperative depression, infection, pulmonary complications, atrial fibrillation, prolonged intensive care unit stay and hospital stay in older elective cardiac surgery patients. No high quality studies were found describing effective interventions to prevent postoperative delirium. We did not find studies specifically targeting the prevention of pressure ulcers in this patient population. CONCLUSIONS Multi-component approaches that include different single interventions have the strongest effect in preventing postoperative depression, pulmonary complications, prolonged intensive care unit stay and hospital stay. Postoperative infection can be best prevented by disinfection with chlorhexidine combined with immune-enhancing nutritional supplements. Atrial fibrillation might be prevented by ingestion of N-3 polyunsaturated fatty acids. High quality studies are urgently needed to evaluate preadmission preventive strategies to reduce postoperative delirium or pressure ulcers in older elective cardiac surgery patients.

Development of a nursing intervention to prepare frail older patients for cardiac surgery (the PREDOCS programme), following phase one of the guidelines of the Medical Research Council

Background: In older patients undergoing elective cardiac surgery, the timely identification and preparation of patients at risk for frequent postoperative hospital complications provide opportunities to reduce the risk of these complications. Aims: We developed an evidence-based, multi-component nursing intervention (Prevention of Decline in Older Cardiac Surgery Patients; the PREDOCS programme) for application in the preadmission period to improve patients’ physical and psychosocial condition to reduce their risk of postoperative complications. This paper describes in detail the process used to design and develop this multi-component intervention. Methods: In a team of researchers, experts, cardiac surgeons, registered cardiac surgery nurses, and patients, the revised guidelines for developing and evaluating complex interventions of the Medical Research Council (MRC) were followed, including identifying existing evidence, identifying and developing theory and modelling the process and outcomes. Additionally, the criteria for reporting the development of complex interventions in healthcare (CReDECI) were followed. Results: The intervention is administered during a consultation by the nurse two to four weeks before the surgery procedure. The consultation includes three parts: a general part for all patients, a second part in which patients with an increased risk are identified, and a third part in which selected patients are informed about how to prepare themselves for the hospital admission to reduce their risk. Conclusions: Following the MRC guidelines, an extended, stepwise, multi-method procedure was used to develop the multi-component nursing intervention to prepare older patients for cardiac surgery, creating transparency in the assumed working mechanisms. Additionally, a detailed description of the intervention is provided.

HELP! Problems in executing a pragmatic, randomized, stepped wedge trial on the Hospital Elder Life Program to prevent delirium in older patients

BackgroundA pragmatic, stepped wedge trial design can be an appealing design to evaluate complex interventions in real-life settings. However, there are certain pitfalls that need to be considered. This paper reports on the experiences and lessons learned from the conduct of a cluster randomized, stepped wedge trial evaluating the effect of the Hospital Elder Life Program (HELP) in a Dutch hospital setting to prevent older patients from developing delirium.MethodsWe evaluated our trial which was conducted in eight departments in two hospitals in hospitalized patients aged 70 years or older who were at risk for delirium by reflecting on the assumptions that we had and on what we intended to accomplish when we started, as compared to what we actually realized in the different phases of our study. Lessons learned on the design, the timeline, the enrollment of eligible patients and the use of routinely collected data are provided accompanied by recommendations to address challenges.ResultsThe start of the trial was delayed which caused subsequent time schedule problems. The requirement for individual informed consent for a quality improvement project made the inclusion more prone to selection bias. Most units experienced major difficulties in including patients, leading to excluding two of the eight units from participation. This resulted in failing to include a similar number of patients in the control condition versus the intervention condition. Data on outcomes routinely collected in the electronic patient records were not accessible during the study, and appeared to be often missing during analyses.ConclusionsThe stepped wedge, cluster randomized trial poses specific risks in the design and execution of research in real-life settings of which researchers should be aware to prevent negative consequences impacting the validity of their results. Valid conclusions on the effectiveness of the HELP in the Dutch hospital setting are hampered by the limited quantity and quality of routine clinical data in our pragmatic trial. Executing a stepped wedge design in a daily practice setting using routinely collected data requires specific attention to ethical review, flexibility, a spacious time schedule, the availability of substantial capacity in the research team and early checks on the data availability and quality.Trial registrationNetherlands Trial Register, identifier: NTR3842.

Interventions to prevent malnutrition in older community-dwelling patients : a systematic review

Background: Cancer is considered as chronic condition, especially in the older people. Prevalence of cancer is especially high in the Nordic countries and Mediterranean countries. People with cance ...Background: To measure the attitudes towards older people and perceptions of working with older people of undergraduate health and social care students in 5 European countries. Questionnaires are one of the most widely used data collection methods. The use of questionnaires constructed and validated in a setting to other setting is an essential aspect in international studies, which have as main objective to compare and deduce similarities and differences within different contexts. There are three main aspects in validation, the linguistic, the cultural and statistic validation,all these three aspects are essential during theprocess. Materials: Two questionnaires were used: Attitudes towards Older People Scale (Kogan1966) and Students’ Perception of Working with Older People Scale (Nolan et al, 2006). Methods: Five Countries were involved in the study namely Ireland, Finland, Germany, Latvia, and Italy. Back translation methodology was used in order to translate questionnaire (Linguistic and cultural validation) while a Cronbach was calculate to assess internal validity (statistic validation). Results: Students (n = 955) completed the two questionnaires. Students’ Perception of Working with Older People Scale, shows a 0.81 a Cronbach for all sample, for Ireland 0.84, Germany, 0.79, Italy 0.79, Finland 0.84 and Latvia 0.59, Attitudes towards Older People Scale shows a 0.83 a Cronbach for all sample,for Ireland 0.85, Germany, 0.83, Italy 0.62, Finland 0.86 and Latvia 0.74. Respondents were generally positive towards older people with few differences between countries. Those with least experience with older people displayed more negative attitudes. Significant relationships were found between positive 50

Feasibility of a nursing intervention to prepare frail older patients for cardiac surgery: A mixed-methods study

Background: Given the growing number of vulnerable, older cardiac surgery patients, the preadmission PREvention Decline in Older Cardiac Surgery patients (PREDOCS) programme was developed to reduce the incidence of postoperative complications. Before the clinical effects of such a complex multicomponent intervention can be evaluated, the feasibility needs to be determined to detect possible problems with the acceptability, compliance and delivery. Aim: The purpose of this study was to test the PREDOCS programme on its feasibility and estimate theoretical cost savings. Methods: In a mixed-methods multicentre study, the Medical Research Council (MRC) guidelines concerning testing feasibility were followed, and theoretical cost savings were calculated. We used data from interviews and the continuous data registry at three hospitals. The results were reported following the criteria for reporting the feasibility of complex interventions (CReDECI). Results: Twenty-one females and 49 males out of 114 eligible patients completed the intervention and provided full data. Patients were equally satisfied with the usual care and the PREDOCS programme (satisfaction rate respectively standard deviation (SD): 7.5 (95% confidence interval (CI): 6.4–8.7) and 7.6 (6.6–8.6)). The involved nurses were satisfied with the tools for guiding patients to reduce their risk of postoperative complications and considered the PREDOCS programme as complementary to usual care. Integrating PREDOCS into current hospital structures appeared to be difficult. Both patients and nurses indicated that the additional consult was tiresome for the patient. The PREDOCS programme will be cost-effective when postoperative complications are prevented in six to sixteen of 1000 cardiac surgery patients. Conclusions: The PREDOCS programme is acceptable for patients and nurses but should be built into the hospital’s cardiac surgery pathway or applied in home care.

Understanding Older People’s Readiness for Receiving Telehealth: Mixed-Method Study

Background The Dutch Ministry of Health has formulated ambitious goals concerning the use of telehealth, leading to subsequent changes compared with the current health care situation, in which 93% of care is delivered face-to-face. Since most care is delivered to older people, the prospect of telehealth raises the question of whether this population is ready for this new way of receiving care. To study this, we created a theoretical framework consisting of 6 factors associated with older people’s intention to use technology. Objective The objective of this study was to understand community-dwelling older people’s readiness for receiving telehealth by studying their intention to use videoconferencing and capacities for using digital technology in daily life as indicators. Methods A mixed-method triangulation design was used. First, a cross-sectional survey study was performed to investigate older people’s intention to use videoconferencing, by testing our theoretical framework with a multilevel path analysis (phase 1). Second, for deeper understanding of older people’s actual use of digital technology, qualitative observations of older people executing technological tasks (eg, on a computer, cell phone) were conducted at their homes (phase 2). Results In phase 1, a total of 256 people aged 65 years or older participated in the survey study (50.0% male; median age, 70 years; Q1-Q3: 67-76). Using a significance level of .05, we found seven significant associations regarding older people’s perception of videoconferencing. Older people’s (1) intention to use videoconferencing was predicted by their performance expectancy (odds ratio [OR] 1.26, 95% CI 1.13-1.39), effort expectancy (OR 1.23, 95% CI 1.07-1.39), and perceived privacy and security (OR 1.30, 95% CI 1.17-1.43); (2) their performance expectancy was predicted by their effort expectancy (OR 1.38, 95% CI 1.24-1.52); and (3) their effort expectancy was predicted by their self-efficacy (OR 1.55, 95% CI 1.42-1.68). In phase 2, a total of 6 men and 9 women aged between 65 and 87 years participated in the qualitative observation study. Of the primary themes, 5 themes were identified that could provide greater understanding of older people’s capacities and incapacities in using digital technology: (1) “self-efficacy and digital literacy,” (2) “obstacles to using technology,” (3) “prior experience and frequency of use,” (4) “sources of support and facilitating conditions,” and (5) “performance expectancy.” These 5 themes recurred in all 15 observations. Conclusions Performance expectancy, effort expectancy, and perceived privacy and security are direct predictors of older people’s intention to use videoconferencing. Self-efficacy appeared to play a role in both older people’s intention to use, as well as their actual use of technology. The path analysis revealed that self-efficacy was significantly associated with older people’s effort expectancy. Furthermore, self-efficacy and digital literacy appeared to play a major role in older people’s capacities to make use of digital technology.

Outpatient preoperative oral nutritional support for undernourished surgical patients: A systematic review

AIMS AND OBJECTIVES To evaluate the effects of preoperative nutritional support using a regular diet for undernourished surgical patients at the outpatient clinic. BACKGROUND Undernutrition (or malnutrition) in surgical patients has severe consequences, that is, more complications, longer hospital stay and decreased quality of life. While systematic reviews show the effects of oral nutritional supplements (ONS), enteral and parenteral nutrition in surgical patients, the effects of normal foods and regular diets remain unclear. DESIGN A systematic review. METHODS PubMed, CINAHL, Web of Science, PsycINFO, Cochrane Library and EMBASE were searched up to July 24, 2017. Studies on undernourished patients receiving nutritional support using regular or therapeutic diet, performed preoperatively at the outpatient clinic, were considered eligible. Risk of bias was assessed using the Cochrane Risk of Bias tool. Two reviewers independently performed study selection, quality assessment and data extraction. RESULTS Six studies with moderate risk of bias were included. Interventions were preoperatively performed in mainly oncological outpatients by dieticians and aimed to reach nutrient requirements. Interventions included consults for counselling and advice, follow-up meetings and encouragements, and ONS. Nutritional status, nutrient intake and quality of life improved in supported patients. Improvements were better in counselled patients compared to patients using supplements. Unsupported patients experienced worse outcomes. CONCLUSION Frequent consults with counselling and advice as nutritional support for undernourished patients before surgery result in improvements to nutritional status, intake and quality of life. This statement is supported by weak evidence due to few studies and inadequate methods. RELEVANCE TO CLINICAL PRACTICE Nutritional support should be provided to all undernourished surgical patients during preoperative course. Nurses are in key position to provide nutritional support during outpatient preoperative evaluations.
