RESUMO

Laboratory e-learning support tools can assist students' learning while preparing for laboratory classes. To successfully work in such virtual experimental environments (VEEs) outside class, students require self-regulated learning (SRL) skills. A deeper understanding of the continuous reciprocal interactions between SRL, satisfaction, and online engagement is needed to develop more effective online learning experiences. This study therefore aimed to explore the interconnection between students' satisfaction with, effort/importance and engagement in an exemplary VEE, and to relate this to their perceived SRL and learning outcomes. Based on surveys in 79 university students, SRL was related to VEE engagement, effort/importance, and satisfaction. VEE engagement and satisfaction were not related to learning outcomes, while SRL and effort were. Students with different SRL also tended to interact differently with the VEE and experienced differing degrees of procedural and feedback support by the e-environment. We conclude that, for optimal learning experience and outcomes, students' effort regulation and SRL need to be supported while interacting with the VEE, preferably by interventions that integrate personalized and adaptive features. This study has implications for designing and optimizing VEEs and indicates that future research should focus on VEEs taking students' SRL and effort regulation into account to support individual learners effectively.

RESUMO

Introduction: In pediatric education, caregivers are increasingly involved to share their perspective. Yet, an in-depth understanding of the perspective-taking process between medical students and caregivers is lacking. This study explored: 1) Which strategies do medical students use to take a caregiver's perspective and which facilitators and constraints do they perceive? 2) Which strategies do caregivers use to share their perspective with students? and 3) How do students' perspective-taking strategies relate to caregivers' perspective-sharing strategies? Methods: In an online lesson: two caregivers of pediatric patients, shared their story with 27 fourth-year Dutch medical students. After the session, students undertook an assignment where they individually reflected on how they took perspective. Students' reflections were collected via audio recordings. Caregivers were individually interviewed. Data were analyzed through thematic and cross-case analysis. Results: Students used eight perspective-taking strategies, in various combinations. Students used inferential strategies, where they made inferences from available information, and cultivating strategies, where they attempted to elicit more information about the caregiver. Students perceived individual-, contextual- and caregiver-related facilitators and constraints for taking perspective. Caregivers shared their perspective by adopting multiple strategies to share their story and create a trusting learning environment. We visualized connections between students' perspective-taking strategies, facilitators/constraints, and caregivers' perspective-sharing strategies. Discussion: By combining data from both perspective-takers (students) and perspective-sharers (caregivers), this study provides a foundation for future research to study perspective-taking between students and patients in an educational context. On a practical level, our findings provide tools for students, patients, and educators to enhance perspective-taking processes.

RESUMO

BACKGROUND: Earlier work within the physical domain showed that acute inflammation changes motivational prioritization and effort allocation rather than physical abilities. It is currently unclear whether a similar motivational framework accounts for the mental fatigue and cognitive symptoms of acute sickness. Accordingly, this study aimed to assess the relationship between fatigue, cytokines and mental effort-based decision making during acute systemic inflammation. METHODS: Eighty-five participants (41 males; 18-30 years (M = 23.0, SD = 2.4)) performed a mental effort-based decision-making task before, 2 h after, and 5 h after intravenous administration of 1 ng/kg bacterial lipopolysaccharide (LPS) to induce systemic inflammation. Plasma concentrations of cytokines (interleukin (IL)-6, IL-8 and tumor necrosis factor (TNF)) and fatigue levels were assessed at similar timepoints. In the task, participants decided whether they wanted to perform (i.e., 'accepted') arithmetic calculations of varying difficulty (3 levels: easy, medium, hard) in order to obtain rewards (3 levels: 5, 6 or 7 points). Acceptance rates were analyzed using a binomial generalized estimated equation (GEE) approach with effort, reward and time as independent variables. Arithmetic performance was measured per effort level prior to the decisions and included as a covariate. Associations between acceptance rates, fatigue (self-reported) and cytokine concentration levels were analyzed using partial correlation analyses. RESULTS: Plasma cytokine concentrations and fatigue were increased at 2 h post-LPS compared to baseline and 5 h post-LPS administration. Acceptance rates decreased for medium, but not for easy or hard effort levels at 2 h post-LPS versus baseline and 5 h post-LPS administration, irrespective of reward level. These reductions in acceptance rates occurred despite improved accuracy on the arithmetic calculations itself. Reduced acceptance rates for medium effort were associated with increased fatigue, but not with increased cytokine concentrations. CONCLUSION: Fatigue during acute systemic inflammation is associated with alterations in mental effort allocation, similarly as observed previously for physical effort-based choice. Specifically, willingness to exert mental effort depended on effort and not reward information, while task accuracy was preserved. These results extend the motivational account of inflammation to the mental domain and suggest that inflammation may not necessarily affect domain-specific mental abilities, but rather affects domain-general effort-allocation processes.

RESUMO

Introduction: Patient feedback is becoming ever more important in medical education. Whether students engage with feedback is partly determined by how credible they think the feedback provider is. Despite its importance for feedback engagement, little is known about how medical students judge the credibility of patients. The purpose of this study was therefore to explore how medical students make credibility judgments regarding patients as feedback providers. Methods: This qualitative study builds upon McCroskey's conceptualization of credibility as a three-dimensional construct comprising: competence, trustworthiness, and goodwill. Since credibility judgments are shaped by the context, we studied students' credibility judgments in both a clinical and non-clinical context. Medical students were interviewed after receiving feedback from patients. Interviews were analyzed through template and causal network analysis. Results: Students based their credibility judgments of patients on multiple interacting arguments comprising all three dimensions of credibility. In estimating a patient's credibility, students reasoned about aspects of the patient's competence, trustworthiness, and goodwill. In both contexts students perceived elements of an educational alliance between themselves and patients, which could increase credibility. Yet, in the clinical context students reasoned that therapeutic goals of the relationship with patients might impede educational goals of the feedback interaction, which lowered credibility. Discussion: Students' credibility judgments of patients were a weighing of multiple sometimes conflicting factors, within the context of relationships and their associated goals. Future research should explore how goals and roles can be discussed between students and patients to set the stage for open feedback conversations.

RESUMO

Clinical measurements on breast cancer patients were performed with a three-dimensional tomographic photoacoustic prototype imager (PAM 2). Patients with a suspicious lesion, visiting the center for breast care of a local hospital, were included in the study. The acquired photoacoustic images were compared to conventional clinical images. Of 30 scanned patients, 19 were diagnosed with one or more malignancies, of which a subset of four patients was selected for detailed analysis. Reconstructed images were processed to enhance image quality and the visibility of blood vessels. Processed photoacoustic images were compared to contrast-enhanced magnetic resonance images where available, which aided in localizing the expected tumoral region. In two cases, spotty high-intensity photoacoustic signals could be seen in the tumoral region, attributable to the tumor. One of these cases also displayed a relatively high image entropy at the tumor site, likely related to the chaotic vascular networks associated with malignancies. For the other two cases, it was not possible to identify features indicative of malignancy, because of limitations in the illumination scheme and difficulties in locating the region of interest in the photoacoustic image.

RESUMO

A key component of the Enhanced Recovery After Surgery pathway for esophagectomy is early mobilization. Evidence on a specific protocol of early and structured mobilization is scarce, which explains variation in clinical practice. This study aims to describe and evaluate the early mobilization practice after esophagectomy for cancer in a tertiary referral center in the Netherlands. This retrospective cohort study included data from a prospectively maintained database of patients who underwent an esophagectomy between 1 January 2015 and 1 January 2020. Early mobilization entailed increase in activity with the first target of ambulating 100 meters. Primary outcomes were the number of postoperative days (PODs) until achieving this target and reasons for not achieving this target. Secondary outcomes were the relationship between preoperative factors (e.g. sex, BMI) and achieving the target on POD1, and the relationship between achieving the target on POD1 and postoperative outcomes (i.e. length of stay, readmissions). In total, 384 patients were included. The median POD of achieving the target was 2 (IQR 1-3), with 173 (45.1%) patients achieving this on POD1. Main reason for not achieving this target was due to hemodynamic instability (22.7%). Male sex was associated with achieving the target on POD1 (OR = 1.997, 95%CI 1.172-3.403, P = 0.011); achieving this target was not associated with postoperative outcomes. Ambulation up to 100 m on POD1 is achievable in patients after esophagectomy, with higher odds for men to achieve this target. ERAS pathways for post esophagectomy care are encouraged to incorporate 100 m ambulation on POD1 in their guideline as the first postoperative target.

RESUMO

BACKGROUND: The new Dutch training plan for psychiatrists puts more emphasis on life course psychiatry. Subsequently, adjustments in the educational program regarding child and adolescent psychiatric knowledge, skills and attitudes are needed. AIM: A broadly supported agreement and consensus on Dutch national learning objectives of education in child and adolescent psychiatry. METHOD: With a modified Delphi method, a set of preliminary learning objectives formulated by a working group of experts was presented to trainees (n = 9), adult psychiatrists (n = 12), child and adolescent psychiatrists (n = 17) and adult patients and their relatives (n = 15). In two rounds, the learning objectives were commented on, supplemented, scored for relevance and prioritized. RESULTS: Out of 27 original learning objectives, 20 were assessed as important or necessary by over 80% of the respondents (knowledge 7/9, skills 8/10, attitudes 5/8). Two learning objectives were rejected (less than 60% considered these to be important or necessary). Seven learning objectives were re-assessed in a second round as these were modified (5) or added (2). Four of them were rated as important or necessary by over 80% of participants. The following goals were most often prioritized: knowledge about healthy development and intergenerational issues; ability to make contact with children and families and to integrate protective and risk factors of the child and environment; and knowing one’s own limitations of child psychiatric themes. CONCLUSION: A Delphi study helped gain support from stakeholders for adjustments in training and education by creating consensus about child psychiatric learning goals for general psychiatric training.

RESUMO

OBJECTIVE: To prepare medical students for a rapidly changing healthcare landscape, where new means of communication emerge, innovative teaching methods are needed. We developed a project-based learning course in which medical students design audiovisual patient information in collaboration with patients and with students in Communication and Information Sciences (CIS). We studied what learning mechanisms are triggered in medical students by elements of a project-based-learning course. METHODS: In this qualitative study, twelve sixth year medical students that participated in the course were individually interviewed. Data were analyzed according to the principles of qualitative template analysis. RESULTS: We identified four learning mechanisms: Challenging assumptions about patients' information needs; Becoming aware of the origin of patients' information needs; Taking a patient's perspective; Analyzing language to adapt to patients' needs. These learning mechanisms were activated by making a knowledge clip, collaborating with patients, and collaborating with CIS students. CONCLUSION: Collaborating with patients helped students to recognize and understand patients' perspectives. Working on a tangible product in partnership with patients and CIS students, triggered students to apply their understanding in conveying information back to patients. PRACTICE IMPLICATION: Based on our findings we encourage educators to involve patients as collaborators in authentic assignments for students so they can apply what they learned from taking patients' perspectives.

RESUMO

BACKGROUND: Serum TGF-ß1 concentrations are reported to be elevated in chronic fatigue syndrome (CFS). However, measurement of circulating cytokines is a complex procedure and control of pre-analytical procedures is essential. The objective of the current study was to measure circulating TGF-ß1 concentrations in CFS patients compared to healthy controls, taking into account differences in pre-analytical procedures. METHODS: Two cohorts of female CFS patients were included. In both studies patients were asked to bring a healthy, age-matched control. At baseline, TGF-ß1 levels were measured in plasma and additionally P-selectin, a marker of platelet activity, was determined in a subgroup of participants. RESULTS: 50 patients and 48 controls were included in cohort I, and 90 patients and 29 controls in cohort II. Within the cohorts there were no differences in TGF-ß1 concentrations. However, between the cohorts there was a large discrepancy, which appeared to be caused by differences in g-force of the centrifuges used. The lower g-force used in cohort II (1361 g) caused more platelet activation, reflected by higher p-selectin concentrations, compared to cohort I (p < 0.0001), which was confirmed in a second independent experiment. There was a correlation between TGF-ß1 and p-selectin concentrations (r 0.79, p < 0.0001). CONCLUSION: These results demonstrate that control of pre-analytical procedures is an essential aspect when measuring circulating cytokines. No evidence for enhanced TGF-ß1 in patients with CFS was found.

RESUMO

BACKGROUND: Over the last few years, telerehabilitation services have developed rapidly, and patients value benefits such as reduced travelling barriers, flexible exercise hours, and the possibility to better integrate skills into daily life. However, the effects of physiotherapy with telerehabilitation on postoperative functional outcomes compared with usual care in surgical populations are still inconclusive. OBJECTIVES: To study the effectiveness of physiotherapy with telerehabilitation on postoperative functional outcomes and quality of life in surgical patients. DATA SOURCES: Relevant studies were obtained from MEDLINE, EMBASE, CINAHL, the Cochrane Library, PEDro, Google Scholar and the World Health Organization International Clinical Trials Registry Platform. STUDY SELECTION: Randomised controlled trials, controlled clinical trials, quasi-randomised studies and quasi-experimental studies with comparative controls were included with no restrictions in terms of language or date of publication. DATA EXTRACTION AND SYNTHESIS: Methodological quality was assessed using the Cochrane risk of bias tool. Twenty-three records were included for qualitative synthesis. Seven studies were eligible for quantitative synthesis on quality of life, and the overall pooled standardised mean difference was 1.01 (95% confidence interval 0.18 to 1.84), indicating an increase in favour of telerehabilitation in surgical patients. LIMITATIONS: The variety in contents of intervention and outcome measures restricted the performance of a meta-analysis on all clinical outcome measures. CONCLUSIONS: Physiotherapy with telerehabilitation has the potential to increase quality of life, is feasible, and is at least equally effective as usual care in surgical populations. This may be sufficient reason to choose physiotherapy with telerehabilitation for surgical populations, although the overall effectiveness on physical outcomes remains unclear. PROSPERO registration number: CRD42015017744.

RESUMO

BACKGROUND: Hip fracture in older patients often lead to permanent disabilities and can result in mortality. OBJECTIVE: To identify distinct disability trajectories from admission to one-year post-discharge in acutely hospitalized older patients after hip fracture. DESIGN: Prospective cohort study, with assessments at admission, three-months and one-year post-discharge. SETTING AND PARTICIPANTS: Patients ≥ 65 years admitted to a 1024-bed tertiary teaching hospital in the Netherlands. METHODS: Disability was the primary outcome and measured with the modified Katz ADL-index score. A secondary outcome was mortality. Latent class growth analysis was performed to detect distinct disability trajectories from admission and Cox regression was used to analyze the effect of the deceased patients to one-year after discharge. RESULTS: The mean (SD) age of the 267 patients was 84.0 (6.9) years. We identified 3 disability trajectories based on the Katz ADL-index score from admission to one-year post-discharge: 'mild'- (n=54 (20.2%)), 'moderate'- (n=110 (41.2%)) and 'severe' disability (n=103 (38.6%)). Patients in all three trajectories showed an increase of disabilities at three months, in relation to baseline and 80% did not return to baseline one-year post-discharge. Seventy-three patients (27.3%) deceased within one-year post-discharge, particularly in the 'moderate'- (n=22 (8.2%)) and 'severe' disability trajectory (n=47 (17.6%)). CONCLUSIONS: Three disability trajectories were identified from hospital admission until one-year follow-up in acutely hospitalized older patients after hip fracture. Most patients had substantial functional decline and 27% of the patient's deceased one-year post-discharge, mainly patients in the 'moderate'- 'and severe' disability trajectories.

RESUMO

BACKGROUND: Depression is one of the most common and debilitating non-motor symptoms of Parkinson's disease (PD). The neurocognitive mechanisms underlying depression in PD are unclear and treatment is often suboptimal. METHODS: We investigated the role of striatal dopamine in reversal learning from reward and punishment by combining a controlled medication withdrawal procedure with functional magnetic resonance imaging in 22 non-depressed PD patients and 19 PD patients with past or present depression. RESULTS: PD patients with a depression (history) exhibited impaired reward v. punishment reversal learning as well as reduced reward v. punishment-related BOLD signal in the striatum (putamen) compared with non-depressed PD patients. No effects of dopaminergic medication were observed. CONCLUSIONS: The present findings demonstrate that impairments in reversal learning from reward v. punishment and associated striatal signalling depend on the presence of (a history of) depression in PD.

RESUMO

Preoperative functional status is a risk factor for developing postoperative complications (POC) in major abdominal and thoracic surgery, but this has hardly been evaluated in esophageal cancer patients undergoing esophagectomy. The aim of this prospective cohort study was to determine if preoperative functional status in esophageal cancer patients is associated with POC. From March 2012 to October 2014, esophageal cancer patients scheduled for esophagectomy at the outpatient clinic of a large tertiary referral center were eligible for the study. We measured inspiratory muscle strength, hand grip strength, physical activities, and health related quality of life as indicators of functional status one day before surgery. POC were scored according to the Clavien-Dindo Classification. We used univariate and multivariate backward regression analysis to determine the association between functional status and POC. We included 94 patients in the study and esophagectomy was performed in 90 patients from which 55 developed POC (61.1%). After multivariate analysis, none of the indicators of preoperative functional status were independently associated with POC (inspiratory muscle strength [OR 1.00; P = 0.779], hand grip strength [OR 0.99; P = 0.250], physical activities [OR 1.00; P = 0.174], and health related quality of life [OR 1.02; P = 0.222]). We concluded that preoperative functional status in our study cohort is not associated with POC after esophagectomy.

RESUMO

Eye tracking research has been conducted for decades to gain understanding of visual diagnosis such as in radiology. For educational purposes, it is important to identify visual search patterns that are related to high perceptual performance and to identify effective teaching strategies. This review of eye-tracking literature in the radiology domain aims to identify visual search patterns associated with high perceptual performance. Databases PubMed, EMBASE, ERIC, PsycINFO, Scopus and Web of Science were searched using 'visual perception' OR 'eye tracking' AND 'radiology' and synonyms. Two authors independently screened search results and included eye tracking studies concerning visual skills in radiology published between January 1, 1994 and July 31, 2015. Two authors independently assessed study quality with the Medical Education Research Study Quality Instrument, and extracted study data with respect to design, participant and task characteristics, and variables. A thematic analysis was conducted to extract and arrange study results, and a textual narrative synthesis was applied for data integration and interpretation. The search resulted in 22 relevant full-text articles. Thematic analysis resulted in six themes that informed the relation between visual search and level of expertise: (1) time on task, (2) eye movement characteristics of experts, (3) differences in visual attention, (4) visual search patterns, (5) search patterns in cross sectional stack imaging, and (6) teaching visual search strategies. Expert search was found to be characterized by a global-focal search pattern, which represents an initial global impression, followed by a detailed, focal search-to-find mode. Specific task-related search patterns, like drilling through CT scans and systematic search in chest X-rays, were found to be related to high expert levels. One study investigated teaching of visual search strategies, and did not find a significant effect on perceptual performance. Eye tracking literature in radiology indicates several search patterns are related to high levels of expertise, but teaching novices to search as an expert may not be effective. Experimental research is needed to find out which search strategies can improve image perception in learners.

RESUMO

BACKGROUND: The study objective was to obtain consensus on physical therapy (PT) in the rehabilitation of critical illness survivors after hospital discharge. Research questions were: what are PT goals, what are recommended measurement tools, and what constitutes an optimal PT intervention for survivors of critical illness? METHODS: A Delphi consensus study was conducted. Panelists were included based on relevant fields of expertise, years of clinical experience, and publication record. A literature review determined five themes, forming the basis for Delphi round one, which was aimed at generating ideas. Statements were drafted and ranked on a 5-point Likert scale in two additional rounds with the objective to reach consensus. Results were expressed as median and semi-interquartile range, with the consensus threshold set at ≤0.5. RESULTS: Ten internationally established researchers and clinicians participated in this Delphi panel, with a response rate of 80 %, 100 %, and 100 % across three rounds. Consensus was reached on 88.5 % of the statements, resulting in a framework for PT after hospital discharge. Essential handover information should include information on 15 parameters. A core set of outcomes should test exercise capacity, skeletal muscle strength, function in activities of daily living, mobility, quality of life, and pain. PT interventions should include functional exercises, circuit and endurance training, strengthening exercises for limb and respiratory muscles, education on recovery, and a nutritional component. Screening tools to identify impairments in other health domains and referral to specialists are proposed. CONCLUSIONS: A consensus-based framework for optimal PT after hospital discharge is proposed. Future research should focus on feasibility testing of this framework, developing risk stratification tools and validating core outcome measures for ICU survivors.

RESUMO

Photoacoustic (optoacoustic) imaging can visualize vasculature deep in tissue using the high contrast of hemoglobin to light, with the high-resolution possible with ultrasound detection. Since angiogenesis, one of the hallmarks of cancer, leads to increased vascularity, photoacoustics holds promise in imaging breast cancer as shown in proof-of-principle studies. Here for the first time, we investigate if there are specific photoacoustic appearances of breast malignancies which can be related to the tumor vascularity, using an upgraded research imaging system, the Twente Photoacoustic Mammoscope. In addition to comparisons with x-ray and ultrasound images, in subsets of cases the photoacoustic images were compared with MR images, and with vascular staining in histopathology. We were able to identify lesions in suspect breasts at the expected locations in 28 of 29 cases. We discovered generally three types of photoacoustic appearances reminiscent of contrast enhancement types reported in MR imaging of breast malignancies, and first insights were gained into the relationship with tumor vascularity.

RESUMO

Formula scoring (FS) is the use of a don't know option (DKO) with subtraction of points for wrong answers. Its effect on construct validity and reliability of progress test scores, is subject of discussion. Choosing a DKO may not only be affected by knowledge level, but also by risk taking tendency, and may thus introduce construct-irrelevant variance into the knowledge measurement. On the other hand, FS may result in more reliable test scores. To evaluate the impact of FS on construct validity and reliability of progress test scores, a progress test for radiology residents was divided into two tests of 100 parallel items (A and B). Each test had a FS and a number-right (NR) version, A-FS, B-FS, A-NR, and B-NR. Participants (337) were randomly divided into two groups. One group took test A-FS followed by B-NR, and the second group test B-FS followed by A-NR. Evidence for impaired construct validity was sought in a hierarchical regression analysis by investigating how much of the participants' FS-score variance was explained by the DKO-score, compared to the contribution of the knowledge level (NR-score), while controlling for Group, Gender, and Training length. Cronbach's alpha was used to estimate NR and FS-score reliability per year group. NR score was found to explain 27 % of the variance of FS [F(1,332) = 219.2, p < 0.0005], DKO-score, and the interaction of DKO and Gender were found to explain 8 % [F(2,330) = 41.5, p < 0.0005], and the interaction of DKO and NR 1.6 % [F(1,329) = 16.6, p < 0.0005], supporting our hypothesis that FS introduces construct-irrelevant variance into the knowledge measurement. However, NR-scores showed considerably lower reliabilities than FS-scores (mean year-test group Cronbach's alphas were 0.62 and 0.74, respectively). Decisions about FS with progress tests should be a careful trade-off between systematic and random measurement error.

RESUMO

BACKGROUND: Post-ICU clinics have been advocated to reduce long-term physical and psychological impairments among ICU survivors. A format for optimal structure, timing, and care content has not yet been established. We developed and implemented two post-ICU clinics in different hospital settings and evaluated the feasibility. METHODS: In this prospective cohort study ICU-survivors of a university hospital (AMC) and a general hospital (TG), who were mechanically ventilated ≥ 2 days and discharged to their homes, were invited to the post-ICU clinic one month after hospital discharge (AMC) or three months after ICU discharge (TG). Feasibility was evaluated as 1) the number of eligible ICU-survivors and the proportion that attended; 2) the prevalence of ICU-related abnormalities, that required referral for further treatment; and 3) patient satisfaction. RESULTS: Forty-five of 629 AMC-patients and 70 of 142 TG-patients were eligible for the post-ICU clinic. Of these, 49% and 67% respectively, visited the outpatient clinic (P=0.026). The majority of all screened patients had functional restrictions, and 68% required referral for further diagnosis and treatment. Patient satisfaction was high. CONCLUSION: This study provides valuable information to support the implementation of post-ICU clinics. The use of validated screening instruments facilitates the identification of patients with need for further treatment. Early in-hospital screening and recruiting patients at highest risk for adverse outcome could be a more targeted approach to achieve greater benefit.

RESUMO

BACKGROUND: With the increasing awareness of postintensive care syndrome and the unbridled development of post-ICU clinics in the Netherlands, guidelines for ICU after care are needed. The purpose of this study was to develop recommendations for the set-up of post-ICU clinics. METHODS: Recommendations regarding the design of post-ICU clinics were formulated based on a survey among Dutch ICUs and the available literature. Subsequently, in a round table conference stakeholders discussed and voted on a final approval of the recommendations. RESULTS: The response rate of our survey was 70% (57 of 82), 40% of the respondents provided ICU after care. Twenty-one people from 16 ICUs participated in the round table conference. Only two studies are available with information on organization and effectiveness of post-ICU clinics. It is recommended to invite patients who are mechanically ventilated for more than 2 days at a post-ICU clinic between 6 and 12 weeks after hospital discharge and screen for physical, psychological and cognitive impairments by using validated electronic patient-reported questionnaires. The set-up of a national registry for benchmarking and research purposes is suggested. CONCLUSION: This study recommends how to organize post-ICU clinics based on literature and expert opinion. The implementation of the recommendations will facilitate the set-up of post-ICU clinics, research on effectiveness of post-ICU clinics and benchmarking of quality of ICU care.
