Accountability in healthcare in the Netherlands: A scoping review.

For better serving people's complex needs the subsequent movement to person-centred integrated care, requires inter-organisational cooperation and service provision by domain-overarching networks and alliances. In the development to these networks, it is relevant to explore which accountability approaches are appropriate for local inter-organisational healthcare governance. Therefore, in a scoping review we studied the current state of knowledge and practice of accountability in healthcare in the Netherlands. We found that two of the included 41 studies show characteristics of accountability towards healthcare with characteristics of integration care components, such as integration of services with accompanying accountability arrangements and development of networked accountability. The first studies are found in the literature which report on accountability in integrated care. With this we add to the international discussion about accountability as an aspect of integrated care governance, by providing insight into the current state of art of accountability in Dutch healthcare.

Development of a microlearning intervention regarding nursing nutritional care for older adults: A multi-methods study.

BACKGROUND: Nutritional care for older adults provided by hospital and home care nurses and nursing assistants is suboptimal. This is due to several factors including professionals' lack of knowledge and low prioritisation. Affecting these factors may promote nurses' and nursing assistants' behavioral change and eventually improve nutritional care. To increase the likelihood of successfully targeting these factors, an evidence-based educational intervention is needed. OBJECTIVES: To develop an educational intervention for hospital and home care nurses and nursing assistants to promote behaviour change by affecting factors that influence current behaviour in nutritional care for older adults. In this paper, we describe the intervention development process. DESIGN: A multi-methods approach using literature and expert input. SETTINGS: Hospital and home care. PARTICIPANTS: Older adults, nurses, nursing assistants, experts, and other professionals involved in nutritional care. METHODS: The educational intervention was based on five principles: 1) interaction between intervention and users, 2) targeting users on both individual and team level, 3) supporting direct and easy transfer to the workplace, and continuous learning, 4) facilitating learning within an appropriate period, and 5) fitting with the context. Consistent with these principles, the research team focussed on developing a microlearning intervention and they established consensus on seven features of the intervention: content, provider, mode of delivery, setting, recipient, intensity, and duration. RESULTS: The intervention consisted of 30 statements about nursing nutritional care for older adults, which nurses and nursing assistants were asked to confirm or reject, followed by corresponding explanations. These can be presented in a snack-sized way, this means one statement per day, five times a week over a period of six weeks through an online platform. CONCLUSIONS: Based on a well-founded and comprehensive procedure, the microlearning intervention was developed. This intervention has the potential to contribute to nursing nutritional care for older adults.

Factors Influencing Nurses' Behavior in Nutritional Care for Community-Dwelling Older Adults Before, During, and After Hospitalization: A Delphi Study.

Background To improve nutritional care for community-dwelling older adults before, during, and after hospitalization, factors influencing nurses' current behavior should be targeted. The aim of this study was to obtain expert consensus on which factors influencing the behavior of hospital and home care nurses are most relevant, modifiable, and feasible to influence. Method In a two-round Delphi study, nine pre-selected factors were rated by 26 experts. Results Eight factors were rated as relevant, modifiable, and feasible to influence: (1) lack of sufficient knowledge, (2) mainly neutral attitude, (3) low prioritization, (4) ambiguous motivation to routinely use guidelines and screening tools, (5) moderate awareness about risk factors, (6) lack of sense of involving informal caregivers, (7) ambiguous motivation to follow education and training, and (8) strong focus on medical nutrition. Conclusion The expert panel reached consensus on eight factors influencing nurses' current behavior. To enhance nutritional care to prevent malnutrition in older adults, strategies are needed for targeting these factors in nursing practice, education, and research.

Older Adults' and Their Informal Caregivers' Experiences and Needs regarding Nutritional Care Provided in the Periods before, during and after Hospitalization: A Qualitative Study.

To enhance prevention and treatment of malnutrition in older adults before, during and after hospitalization, deeper understanding of older adults' and informal caregivers' perspective on nutritional care is important. One-time in-depth interviews were conducted with 15 older adults who had been discharged from hospital, and seven informal caregivers. We explored their experiences and needs regarding nutritional care provided in the periods before, during and after hospitalization. Five themes emerged from the data: (1) dietary intake, (2) food service during hospitalization, (3) nutrition-related activities, (4) whose job it is to give nutritional care, and (5) competing care priorities. Further, several opinions about nutritional issues were identified. Older adults and informal caregivers did not always experience optimal nutritional care. When discussing nutritional care, they mainly focused on the in-hospital period. When providing nutritional care and developing guidelines, older adults' and informal caregivers' perspective on nutritional care should be incorporated. Here, the periods before, during and after hospitalization should be taken into account equally.

Hospital and home care nurses' experiences and perceptions regarding nutritional care for older adults to prevent and treat malnutrition: A cross-sectional study.

AIMS AND OBJECTIVES: To gain insight into the experiences and perceptions of hospital and home care nurses regarding nutritional care for older adults to prevent and treat malnutrition. BACKGROUND: In-depth knowledge about hospital and home care nurses' experiences and perceptions can contribute to optimise nutritional care for older adults across the care continuum between hospital and home to prevent and treat malnutrition. DESIGN: Multicentre cross-sectional descriptive study. METHOD: A validated questionnaire addressing malnutrition was used. A total of 1,135 questionnaires were sent to hospital and home care nurses. The STROBE statement was followed for reporting. RESULTS: The response rate was 49% (n = 556). Of all the nurses, 37% perceived the prevalence of malnutrition among their care recipients between 10% and 25%. Almost 22% of the nurses neither agreed nor disagreed or disagreed with the statement that prevention of malnutrition is possible. More than 28% of the nurses reported that malnutrition is a small or no problem. Over 95% of the hospital nurses and 52.5% of the home care nurses stated they screened routinely for malnutrition. The nurses considered several interventions for treating malnutrition important. Over 81% of the nurses indicated they wanted to follow further training. CONCLUSION: Most hospital and home care nurses perceived that nutritional care for older adults to prevent and treat malnutrition was important. A fair group of nurses, however, had the opposite perception. RELEVANCE TO CLINICAL PRACTICE: Raising the awareness of all hospital and home care nurses about the importance of nutritional care for older adults is pivotal to increase the chance of successfully providing nursing nutritional care. Nurses should follow training for consolidation of nutritional care. Nurses are well-positioned to take a leadership role to improve continuity and quality of nutritional care across the care continuum between hospital and home.

Educational intervention to increase nurses' knowledge, self-efficacy and usage of telehealth: A multi-setting pretest-posttest study.

The widespread use of telehealth, providing healthcare remotely, is hampered by various barriers. Dutch nurses currently working in practice never received education in this new way of healthcare delivery. Education is frequently suggested as a strategy to overcome barriers in telehealth use. However, the nature and effectiveness of such education has not yet been specified and tested in practice. In a previous study, we identified 14 nursing telehealth activities and accompanying competencies. In the current study, we established the effectiveness of training in these competencies on nurses' subjective knowledge, self-efficacy and usage of telehealth. A two-day tailored training program in nursing telehealth activities was evaluated in a Dutch context among 37 participants across three settings: (a) twelve primary care (PC), (b) fourteen homecare (HC) and (c) eleven hospital (H) nurses. In each team, telehealth knowledge significantly increased during the training sessions. In each team, nurses' telehealth self-efficacy also significantly increased 6-10 weeks after the training. After the training, the number of remote consultations increased from 2 to 12 in primary care, 12 to 35 in homecare and decreased from 28 to 17 in the hospital setting. We conclude that training nurses in telehealth activities contributes to their knowledge and self-efficacy.

Using intervention mapping to develop an outpatient nursing nutritional intervention to improve nutritional status in undernourished patients planned for surgery.

BACKGROUND: Undernutrition in surgical patients leads to a higher risk of postoperative complications like infections and delayed recovery of gastrointestinal functions, often resulting in a longer hospital stay and lower quality of life. Nurses at outpatient clinics can deliver nutritional care during outpatient preoperative evaluation of health status to ensure that patients are properly fed in preparation for hospital admission for surgery. However, nutritional nursing care was not determined in research yet. This paper describes the structural development of an Outpatient Nursing Nutritional Intervention (ONNI). METHODS: A project group followed the steps of the Intervention Mapping. The needs assessment included assessment of delivery of nutritional care and nutritional care needs at two anaesthesia outpatient clinics of an academic and a teaching hospital. Also, outpatient clinic nurses and patients at risk for undernutrition were interviewed. Determinants resulted from these methods were matched with theories on behaviour change and nutritional support. RESULTS: Both patients and nurses were unaware of the consequences of undernutrition, and nurses were also unaware of their roles with regard to nutritional support. The intervention goals were: 1) enabling surgical patients to improve or maintain their nutritional status before hospital admission for surgery, and 2) enabling nurses to deliver nutritional support. The ONNI was developed for outpatients at risk for or with undernutrition. A training was developed for nurses. The ONNI included the five following components: 1) identification of the causes of undernutrition; 2) provision of a nutritional care plan including general and individually tailored advice; 3) self-monitoring of nutrient intake; 4) counselling and encouragement; and 5) support during a telephone follow-up meeting. The intervention and training were tested. A multifaceted implementation strategy was used to deliver the intervention in daily practice. CONCLUSIONS: Despite the unique position of the nurses at outpatient clinics, nurses were unaware of their role with regard to nutritional care. The ONNI was developed and implemented along with a training program for nurses. The test confirmed that the training can improve nurses' knowledge, skills, and sense of responsibility for nutritional support. The intervention may empower patients to actively improve their nutritional status.

Interventions to prevent and treat malnutrition in older adults to be carried out by nurses: A systematic review.

AIMS AND OBJECTIVES: To identify interventions to prevent and treat malnutrition in older adults, which can be integrated in nursing care, and to evaluate the effects of these interventions on outcomes related to malnutrition. BACKGROUND: Older adults are at great risk for malnutrition, which can lead to a number of serious health problems. Nurses have an essential role in nutritional care for older adults. Due to a lack of evidence for nursing interventions, adequate nursing nutritional care still lags behind. DESIGN: Systematic review. METHOD: We searched for and included randomised controlled trials on interventions, which can be integrated in nursing care for older adults, to prevent and treat malnutrition. We assessed the risk of bias with the Cochrane tool and evidence for outcomes with the GRADE. The PRISMA statement was followed for reporting. RESULTS: We included 21 studies of which 14 studies had a high risk of bias. Identified interventions were oral nutritional supplements, food/fluid fortification or enrichment, dietary counselling and educational interventions. In evaluating the effects of these interventions on 11 outcomes related to malnutrition, significant and nonsignificant effects were found. We graded the certainty of evidence as very low to moderate. CONCLUSION: Although slight effects were found in protein intake and body mass index, there is no convincing evidence about the effectiveness of the four identified interventions. There seems no harm in using these interventions, although it should be kept in mind that the evidence is sparse. Therefore, there is a need for high-quality research in building evidence for interventions in nursing nutritional care. RELEVANCE TO CLINICAL PRACTICE: Nurses can safely provide oral nutritional supplements and food/fluid fortification or enrichment, and give dietary counselling and education to older adults, as they are well placed to lead the essential processes of nutritional care to older adults.

Implementation, Mechanisms of Effect and Context of an Integrated Care Intervention for Vulnerable Families in Central Sydney Australia: A Research and Evaluation Protocol.

INTRODUCTION: In March 2014, the New South Wales (NSW) Government (Australia) announced the NSW Integrated Care Strategy. In response, a family-centred, population-based, integrated care initiative for vulnerable families and their children in Sydney, Australia was developed. The initiative was called Healthy Homes and Neighbourhoods. A realist translational social epidemiology programme of research and collaborative design is at the foundation of its evaluation. THEORY AND METHOD: The UK Medical Research Council (MRC) Framework for evaluating complex health interventions was adapted. This has four components, namely 1) development, 2) feasibility/piloting, 3) evaluation and 4) implementation. We adapted the Framework to include: critical realist, theory driven, and continuous improvement approaches. The modified Framework underpins this research and evaluation protocol for Healthy Homes and Neighbourhoods. DISCUSSION: The NSW Health Monitoring and Evaluation Framework did not make provisions for assessment of the programme layers of context, or the effect of programme mechanism at each level. We therefore developed a multilevel approach that uses mixed-method research to examine not only outcomes, but also what is working for whom and why.

Hospital Nurses' Self-Reported Confidence in Their Telehealth Competencies.

BACKGROUND: The diffusion of telehealth into hospital care is still low, partially because of a lack of telehealth competence among nurses. In an earlier study, we reported on the knowledge, skills, and attitudes (KSAs) nurses require for the use of telehealth. The current study describes hospital nurses' confidence in possessing these telehealth KSAs. METHOD: In a cross-sectional study, we invited 3,543 nurses from three hospitals in the Netherlands to rate their self-confidence in 31 telehealth KSAs on a 5-point Likert scale, using an online questionnaire. RESULTS: A total of 1,017 nurses responded to the survey. Nine KSAs were scored with a median value of 4.0, 19 KSAs with a median value of 3.0, and three KSAs with a median value of 2.0. CONCLUSION: Given that hospital nurses have self-confidence in only nine of the 31 essential telehealth KSAs, continuing education in additional KSAs is recommended to support nurses in gaining confidence in using telehealth.

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.

Increasing value and reducing waste by optimizing the development of complex interventions: Enriching the development phase of the Medical Research Council (MRC) Framework.

BACKGROUND: In recent years there has been much emphasis on 'research waste' caused by poor question selection, insufficient attention to previous research results, and avoidable weakness in research design, conduct and analysis. Little attention has been paid to the effect of inadequate development of interventions before proceeding to a full clinical trial. OBJECTIVE: We therefore propose to enrich the development phase of the MRC Framework by adding crucial elements to improve the likelihood of success and enhance the fit with clinical practice METHODS: Based on existing intervention development guidance and synthesis, a comprehensive iterative intervention development approach is proposed. Examples from published reports are presented to illustrate the methodology that can be applied within each element to enhance the intervention design. RESULTS: A comprehensive iterative approach is presented by combining the elements of the MRC Framework development phase with essential elements from existing guidance including: problem identification, the systematic identification of evidence, identification or development of theory, determination of needs, the examination of current practice and context, modelling the process and expected outcomes leading to final element: the intervention design. All elements are drawn from existing models to provide intervention developers with a greater chance of producing an intervention that is well adopted, effective and fitted to the context. CONCLUSION: This comprehensive approach of developing interventions will strengthen the internal and external validity, minimize research waste and add value to health care research. In complex interventions in health care research, flaws in the development process immediately impact the chances of success. Knowledge regarding the causal mechanisms and interactions within the intended clinical context is needed to develop interventions that fit daily practice and are beneficial for the end-user.

Internet-Generation Nursing Students' View of Technology-Based Health Care.

BACKGROUND: Today's nursing school applicants are considered "digital natives." This study investigated students' views of new health care technologies. METHOD: In a cross-sectional survey among first-year nursing students, 23 common nursing activities and five telehealth nursing activities were presented along with three statements: "I consider this a core task of nursing," "I look forward to becoming trained in this task," and "I think I will do very well in performing this task." RESULTS: Internet-generation nursing students (n = 1,113) reported a significantly (p ⩽ .001) less positive view of telehealth activities than of common nursing activities. Median differences were 0.7 (effect size [ES], -0.54), 0.4 (ES, -0.48), and 0.3 (ES, -0.39), measured on a 7-point scale. CONCLUSION: Internet-generation nursing students do not naturally have a positive view of technology-based health care provision. The results emphasize that adequate technology and telehealth education is still needed for nursing students. [J Nurs Educ. 2017;56(12):717-724.].

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.

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.

Predicting prolonged intensive care unit stays in older cardiac surgery patients: a validation study.

PURPOSE: In cardiac surgery prediction models identifying patients at risk of prolonged stay at the Intensive Care Unit (ICU) are used to optimize treatment and use of ICU resources. A recent systematic validation study of 14 of these models identified three models with a good predictive performance across patients of all ages. It is however unclear how these models perform in older patients, who nowadays form a considerable part of this patient population. The current study specifically validates the performance of these three models in older cardiac surgery patients and quantifies how their performance changes with increasing age of patients. METHODS: The Parsonnet model, the EuroSCORE, and a model by Huijskes and colleagues were validated using prospectively collected data of 11,395 cardiac surgery patients. Performance of the models was described by discrimination (area under the ROC curve, AUC) and calibration. RESULTS: For the Parsonnet model, the EuroSCORE and the Huijskes model discrimination clearly decreased with increasing age (AUCs of 0.76, 0.71 and 0.72 for ages 70-75 and 0.72, 0.70 and 0.72, respectively, for ages 75-80 and 0.68, 0.64 and 0.69, respectively, above 80 years). The models showed poor calibration in patients aged >70 (p values for fit of the models <0.006). CONCLUSIONS: To optimize treatment and ICU resources, risk prediction for prolonged ICU stay after cardiac surgery using the existing models should be done with great care for older patients.

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.
