RESUMO

Cellular stress has been associated with inflammation, yet precise underlying mechanisms remain elusive. In this study, various unrelated stress inducers were employed to screen for sensors linking altered cellular homeostasis and inflammation. We identified the intracellular pattern recognition receptors NOD1/2, which sense bacterial peptidoglycans, as general stress sensors detecting perturbations of cellular homeostasis. NOD1/2 activation upon such perturbations required generation of the endogenous metabolite sphingosine-1-phosphate (S1P). Unlike peptidoglycan sensing via the leucine-rich repeats domain, cytosolic S1P directly bound to the nucleotide binding domains of NOD1/2, triggering NF-κB activation and inflammatory responses. In sum, we unveiled a hitherto unknown role of NOD1/2 in surveillance of cellular homeostasis through sensing of the cytosolic metabolite S1P. We propose S1P, an endogenous metabolite, as a novel NOD1/2 activator and NOD1/2 as molecular hubs integrating bacterial and metabolic cues.

RESUMO

BACKGROUND: Parent and infant separation in the neonatal unit is associated with adverse health outcomes. Family-integrated care has several advantages and the potential to reduce these adverse outcomes but requires parental presence. This study aimed to explore the views of parents and neonatal healthcare professionals (nHCPs) on barriers and facilitators to parental presence in a Swiss neonatal unit and to identify possible differences between nHCPs and parents, and between mothers and fathers. METHODS: Data were collected through semi-structured interviews with parents and focus group discussions with nHCPs. Inductive content analysis was used to identify barriers and facilitators to parental presence in the neonatal unit. RESULTS: Twenty parents (10 mothers and 10 fathers) and 21 nHCPs (10 nurses and 11 physicians) participated in the study. Parents and nHCPs experienced barriers and facilitators related to: (1) Structural factors of the institution, such as infrastructure or travel and distance to the neonatal unit. (2) Organization and time management of parental presence, daily activities, and work. (3) Resources, which include factors related to the legal situation, support services, family, and friends. (4) Physical and psychological aspects, such as pain, which mainly affected mothers, and aspects of emotional distress, which affected both parents. Self-care was an important physical and psychological facilitator. (5) Parent-professional interaction. Parental presence was influenced by communication, relationship, and interaction in infant care; and (6) Cultural aspects and language. Some perspectives differed between mothers and fathers, while the overall views of parents and nHCPs provided complementary rather than conflicting insights. Using visit plans to support the organization, educating nHCPs in knowledge skills and available resources to improve encouragement and information to parents, strengthening parent self-care, and improving nHCPs' attitudes towards parental presence were seen as possible improvements. CONCLUSIONS: Multifactorial barriers and facilitators determine parental presence and experience in the neonatal unit. Parents and nHCPs made specific recommendations to improve parental presence.

RESUMO

AIM: To explore how expectant mothers at risk for preterm birth would like to be involved in decision-making at the margin of viability and what they would base their decisions on. METHODS: This cross-sectional observational study included a mixed-methods post-hoc analysis alongside a previously reported randomised clinical trial. Expectant mothers between 280/7 and 366/7 weeks' gestation who were hospitalised for risk of preterm birth responded to written case vignettes of an impending preterm birth at the margin of viability. Participants responded to closed and open-ended questions that were theoretically coded for attitudes and values towards shared decision-making. RESULTS: Sixty-four expectant mothers were included in the analysis, 36 provided written perspectives. Decision-making was perceived as an enormous burden and a potential source of guilt and regret. Weighing personal values in terms of 'fighting for the baby' and 'quality of life' were used to inform the decision-making process. Explicitly stating that any decision is a good decision, empowerment through co-constructing shared decisions rather than simply presenting choices, sharing the clinicians' personal views, and honest, and empathetic counselling were perceived as supportive. CONCLUSION: Mothers at risk for preterm birth provided specific insights into their decision-making patterns that may be helpful to clinicians.

RESUMO

BACKGROUND: Delirium is a common condition in elderly inpatients. Health care professionals play a crucial role in recognizing delirium, initiating preventive measures and implementing a multicomponent treatment strategy. Yet, delirium often goes unrecognized in clinical routine. Nurses take an important role in preventing and managing delirium. This study assesses clinical reasoning of nurses using case vignettes to explore their competences in recognizing, preventing and managing delirium. METHODS: The study was conducted as an online survey. The questionnaire was based on five case vignettes presenting cases of acutely ill older patients with different subtypes of delirium or diseases with overlapping symptoms. In a first step, case vignettes were developed and validated through a multidisciplinary expert panel. Scoring of response options were summed up to a Geriatric Delirium Competence Questionnaire (GDCQ) score including recognition and management tasks The questionnaire was made available online. Descriptive analyses and group comparisons explores differences between nurses from different settings. Factors explaining variance in participants' score were evaluated using correlations and linear regression models. RESULTS: The questionnaire demonstrated good content validity and high reliability (kappa = 0.79). The final sample consisted of 115 nurses. Five hundred seventy-five case vignettes with an accuracy of 0.71 for the correct recognition of delirium presence or absence were solved. Nurses recognized delirium best in cases describing hyperactive delirium (79%) while hypoactive delirium was recognized least (44%). Nurses from geriatric and internal medicine departments had significantly higher GDCQ-score than the other subgroups. Management tasks were correctly identified by most participants. CONCLUSIONS: Overall, nurses' competence regarding hypoactive delirium should be strengthened. The online questionnaire might facilitate targeting training opportunities to nurses' competence.

RESUMO

BACKGROUND: Chronic cardiovascular diseases demand continuous care from general practitioners and medical specialists. Especially in fragmented healthcare systems, such as in Germany, a large body of research is devoted to the improvement of care continuity. Meanwhile, measuring continuity of care itself has been a challenge due to the absence of validated instruments. In 2011, the Dutch Nijmegen Continuity Questionnaire (NCQ) was developed and validated to measure continuity of care across care settings from the patients' perspectives in the Netherlands. Its applicability in other countries and health systems, however, has rarely been tested. We therefore aimed at assessing the applicability of the Nijmegen Continuity Questionnaire to the German health care context.  METHODS: We translated and applied the original NCQ to an ambulatory cardiovascular care setting in Germany. Qualitative interview data and quantitative survey data on our adaptation were collected from patients in 27 general practices within the German states of Baden-Wuerttemberg and Rhineland-Palatinate. Qualitative data on understandability and clearness of the questionnaire was obtained using semi-structured telephone interviews and think aloud-protocols. Quantitative data was obtained through an anonymous written questionnaire containing the translated NCQ items to assess applicability of our translation. We performed confirmatory and exploratory factor analyses based on the original NCQ-structure mapped to general practitioners and an aggregated analysis of general practitioners and cardiologists combined. RESULTS: A total of 6 patients participated in the interviews and a total of 435 patients participated in the written survey. The interviews showed that, overall, patients had little difficulties comprehending and answering to our translation of the NCQ. The confirmatory factor analyses then showed that the structure of the original NCQ with 12 items and 3 latent factors can also be found in the German context. However, a simpler 2-factor-structure would also fit well with the data. CONCLUSION: A German translation of the NCQ yielded a factor structure comparable to the original version and proved to be understandable for patients. TRIAL REGISTRATION: The project underlying the study was registered on November 7, 2019 in the German Clinical Trials Register ( www.drks.de ) under ID: DRKS00019219.

RESUMO

BACKGROUND: Antimicrobial resistance is a worldwide challenge for health services and systems alike. To reduce the overuse of antibiotics, multifaceted interventions are often used to achieve sustainable effects. It can be assumed that these effects are influenced by contextual factors. Embedded in the cluster randomized trial ARena (Sustainable reduction of antibiotic-induced antimicrobial resistance), the aim of this present study was to identify contextual factors associated with practitioners' perceptions of antibiotic prescribing in German primary health care. METHODS: In a prospective observational study, data were generated in a three-wave survey study between January 2018 and July 2019. Analysis was performed using logistic regression models. The outcome of interest was the physician perceived impact of participating in the ARena project on decision-making regarding antibiotic prescribing, the independent variables of interest included individual characteristics, intervention arm allocation, primary care network (PCN) environment and characteristics of the medical practice. RESULTS: Forty Six point eight percent (n = 126) of participants indicated to have perceived an impact on their decision-making regarding antibiotic prescribing by participating in the ARena project. Bivariate logistic regression analyses indicated that work experience (odds ratio (OR) 1.05, 95% confidence interval (CI) 1.006-1.103), PCN environment (OR 2.06, 95% CI 1.256-3.363), structural conditions (OR 1.66, 95% CI 1.161-2.371), environment of existing processes (OR 1.46, 95% CI 1.011-2.094), and externally defined general conditions (OR 1.57, 95% CI 1.035-2.378) were associated with physicians' perceived impact of participating in the ARena project on decision-making regarding antibiotic prescribing. In the multivariable logistic regression analysis, only work experience OR 1.05 (95% CI 1.001-1.104) continuously showed a significant influence. CONCLUSIONS: This study indicates that contextual factors at individual, practice, and system level influence physicians' perceptions of antibiotic prescribing. Longer work experience appeared to be a significant influencing factor to be considered in antimicrobial stewardship programs. TRIAL REGISTRATION: ISRCTN, ISRCTN58150046 (registered 13.09.2017).

RESUMO

BACKGROUND: Healthcare providers' inclination to seek or lead other providers' opinions on clinical topics may influence healthcare practices, particularly regarding their alignment across different providers in controversial domains. This study aimed to explore opinion-seeking behaviours of general practitioners and their impacts on clinical opinions in ambulatory cardiovascular care in Germany. METHODS: Between 2019 and 2021, we performed a written survey in two samples of general practitioners and one sample of self-employed cardiologists in three German states. The general practitioners were asked to identify a person they deemed influential on their views on cardiovascular conditions. Their self-perceived opinion leadership and opinion seeking behaviours were then measured, using a validated 12-item-questionnaire. General practitioners and cardiologists were requested to indicate their agreement with three potentially controversial aspects of cardiovascular ambulatory care. Potential impacts on the general practitioners' views, including local cardiologists' opinions, were examined using multi-level linear regression models. RESULTS: A total of 129 general practitioners and 113 cardiologists returned the questionnaire. 68.50% of general practitioners named an opinion leader, mainly cardiologists outside of their practice. General practitioners perceived themselves as opinion seeking and as opinion leading at the same time. Views on the presented controversial topics were mixed among both general practitioners and cardiologists. Self-reported opinion leadership behaviour of general practitioners was associated with their views on one of the three topics. No such associations were found for opinion seeking behaviours and the views of local cardiologists. CONCLUSION: While most general practitioners named a cardiovascular opinion leader and saw themselves as opinion seeking regarding cardiovascular issues, they simultaneously perceived themselves as opinion leading, suggesting that opinion leadership and opinion seeking are not mutually exclusive concepts. The views of local cardiologists were not associated with the general practitioners' view, suggesting that local medical specialists do not necessarily influence the surrounding opinion seekers' views per se. TRIAL REGISTRATION: We registered the study prospectively on 7 November 2019 at the German Clinical Trials Register (DRKS, www.drks.de ) under ID no. DRKS00019219.

RESUMO

BACKGROUND: Participation of general practitioners is crucial for health care studies. However, recruiting them is an ongoing challenge and participation rates of general practitioners around the globe are often low. One feasible and cost-efficient approach to potentially enhance participation rates among general practitioners are personalized invitation letters, since they may increase one's attention to and appreciation of a study. Still, evidence whether this method actually affects participation is scarce and ambiguous in relation to physicians. METHODS: We undertook a randomized trial in a sample of general practitioners from three German states in the context of a large, observational study on physicians' coordination and uptake of recommended cardiovascular ambulatory care. An intervention group (n = 757 general practitioners) received a personalized invitation to participate in the observational study, the control group (n = 754 general practitioners) received a generic invitation. Both groups were blinded to group assignment. Eventual participation rates as well as the number and types of responses overall were compared between arms. Besides the main intervention, sociodemographic and geographical context factors were considered as well. RESULTS: The overall participation rate among physicians was 2.6% (2.8% in the intervention group and 2.4% in the control group). No statistically significant effect of personalization on participation of physicians was found (relative risk to participate when receiving a personalized invitation of 1.17 [95%-CI: 0.62, 2.21]). However, the number of responses to the invitation varied significantly between the geographical regions. CONCLUSIONS: Personalization of first written contact alone did not improve research participation among general practitioners, which was overall very low. TRIAL REGISTRATION: The study in which the trial was embedded has been registered prospectively at the German Clinical Trials Register (DRKS) under registration number DRKS00019219 .

RESUMO

Kaposi's sarcoma-associated herpesvirus (KSHV) is one of the few oncogenic human viruses known to date. Its large genome encodes more than 85 proteins and includes both unique viral proteins as well as proteins conserved amongst herpesviruses. KSHV ORF20 is a member of the herpesviral core UL24 family, but the function of ORF20 and its role in the viral life cycle is not well understood. ORF20 encodes three largely uncharacterized isoforms, which we found were localized predominantly in the nuclei and nucleoli. Quantitative affinity purification coupled to mass spectrometry (q-AP-MS) identified numerous specific interacting partners of ORF20, including ribosomal proteins and the interferon-stimulated gene product (ISG) oligoadenylate synthetase-like protein (OASL). Both endogenous and transiently transfected OASL co-immunoprecipitated with ORF20, and this interaction was conserved among all ORF20 isoforms and multiple ORF20 homologs of the UL24 family in other herpesviruses. Characterization of OASL interacting partners by q-AP-MS identified a very similar interactome to that of ORF20. Both ORF20 and OASL copurified with 40S and 60S ribosomal subunits, and when they were co-expressed, they associated with polysomes. Although ORF20 did not have a global effect on translation, ORF20 enhanced RIG-I induced expression of endogenous OASL in an IRF3-dependent but IFNAR-independent manner. OASL has been characterized as an ISG with antiviral activity against some viruses, but its role for gammaherpesviruses was unknown. We show that OASL and ORF20 mRNA expression were induced early after reactivation of latently infected HuARLT-rKSHV.219 cells. Intriguingly, we found that OASL enhanced infection of KSHV. During infection with a KSHV ORF20stop mutant, however, OASL-dependent enhancement of infectivity was lost. Our data have characterized the interaction of ORF20 with OASL and suggest ORF20 usurps the function of OASL to benefit KSHV infection.

RESUMO

BACKGROUND: As the number of elderly and multimorbid patients increases, healthcare has become more complex. This requires good coordination of treatment and care given the various  health care professionals involved (e.g. general practitioners, medical specialists, physicians' assistants). Lack of coordination jeopardizes seamless, evidence-based treatment and care, and eventually reduces clinical effectiveness. The aim of the study is a) to describe and explore information transfer and interprofessional collaboration in ambulatory cardiac care, b) to describe and explore the role of provider networks from the perspective of patients and providers, focusing on healthcare coordination and the uptake of recommended practices. METHODS: Two related studies are planned: a) an observational study of healthcare provider networks, involving 600 patients with chronic (atherosclerosis-related) cardiovascular disease from 40 general practices and up to 320 healthcare providers (general practitioners, medical specialist, physicians' assistants), and b) a qualitative interview study with up to 80 healthcare professionals and patients. Furthermore, we will analyse claims data of a large German health insurer to explore provider networks in ambulatory cardiac care. DISCUSSION: The project aims to provide insight into factors, processes and mechanisms of information transfer and interprofessional collaboration, which affect seamless, evidence-based healthcare practice. This will contribute to the design of strategies for improving health care practice and to the development of measures of coordination for future research. TRIAL REGISTRATION: We registered the study prospectively on 7 November 2019 at the German Clinical Trials Register (DRKS, www.drks.de) under ID no. DRKS00019219 .

RESUMO

Traditional hierarchies and structures in healthcare, as well as traditional professional socialization practices, continue to create barriers to effective interprofessional collaboration. Nevertheless, some studies indicate that early socialization with other health professionals can build bridges and improve understanding of each other's roles and contributions to patient care. This pilot study aimed to gain insights into the nursing and medical students' experiences of interprofessional medical history taking during a collective learning activity. A descriptive case study was conducted using modified interviews based on the speed-dating (SD) technique to explore participants' reasons for the choice of profession (SD1) and experiences of interprofessional history taking (SD2). Data were digitally captured using audio-recordings. An inductive-deductive approach to qualitative content analysis of transcribed responses was undertaken. Eighteen students (medicine n = 6; nursing n = 12) participated. Two main categories with sub-themes emerged from the inductive SD1 analysis: (a) reasons for choosing a career and (b) knowledge about professions. The SD2 deductive analysis identified three major categories with sub-themes: (a) breaking down barriers, (b) interprofessional role learning - interprofessional collaboration and (c) dual-identity development. Our findings showed that early interprofessional socialization of students supported their learning about the complementary roles of doctors and nurses and enabled them to gain early experiences of interprofessional teamwork.

RESUMO

OBJECTIVE: To compare rates of detectability of circulating Rh(D)-immunoglobulin (anti-D) at delivery with single and two-dose antenatal anti-D prophylaxis (RAADP) regimens; to compare compliance with the two regimens. DESIGN: Open label, randomised controlled trial between May 2013 and November 2015. SETTING, PARTICIPANTS: 277 women who attended a tertiary obstetric referral hospital in Perth for antenatal care and were at least 18 years of age, less than 30 weeks pregnant and yet to receive RAADP, Rh(D)-negative (negative antibody screen), and who intended to deliver their baby at the hospital. Exclusion criteria were prior anti-D sensitisation, any contraindication of anti-D administration, and a history of isolated IgA deficiency. INTERVENTIONS: One 1500 IU anti-D dose at 28 weeks of pregnancy (single dose regimen); two doses of 625 IU each at 28 and 34 weeks of pregnancy (two-dose regimen). MAIN OUTCOME MEASURES: The primary outcome was the proportion of women with detectable anti-D levels at delivery; the secondary outcome was compliance with the allocated RAADP regimen. RESULTS: Circulating anti-D was detectable at delivery in a greater proportion of women in the two-dose group (111 of 129, 86%) than in the single dose group (70 of 125, 56%; P < 0.001). Compliance was not significantly different between the single dose (86 of 138, 61%) and two-dose groups (70 of 139, 50%; P = 0.06). CONCLUSIONS: The two-dose RAADP schedule currently recommended in Australia provides better protection against Rh(D) sensitisation than a one-dose regimen. TRIAL REGISTRATION: Australian and New Zealand Clinical Trials Registry (ACTRN12613000661774).

RESUMO

Objective In the past decade, a number of trials have been conducted to determine the optimal strategy of weaning premature infants from nasal continuous airway pressure (nCPAP). However, a paucity of information exists on how weaning is actually performed in clinical routine. Aim of this study was to investigate the current practice of weaning premature infants from nCPAP in Germany. Methods An online survey was performed in German tertiary care neonatal units. Results All 160 German tertiary care units were contacted. Replies were retrieved from 85/160 (53%) units, of which 83/160 (52%) completed the questionnaire. 66/83 (80%) respondents indicated to wean without the use of formal written policies. In 44/83 (53%) units weaning decisions are made jointly between physicians and nurses, whereas physicians are the sole decision makers in 33/83 (40%) as are nurses in 6/83 (7%) units. Many units use more than one weaning strategy. 81/83 units (98%) gradually reduce nCPAP pressure as the initial step in the weaning process. 9/83 (11%) units stop nCPAP at standard criteria [CICADA (CeasIng nCpap At standarD criteriA) method] and 58/83 (70%) units use a cycling nCPAP on/off strategy. 52/83 (63%) of the responding units use nasal high flow at least at some point during the weaning process, either as a gradual weaning method or during nCPAP breaks. Conclusion Weaning strategies from nCPAP vary widely in German tertiary care neonatal units. It appears that evidence is still insufficient to promote a distinct weaning strategy which in turn highlights the urgent need for further adequately powered clinical trials.

RESUMO

Excitatory and inhibitory balance of neuronal network activity is essential for normal brain function and may be of particular importance to memory. Apolipoprotein (apo) E4 and amyloid-ß (Aß) peptides, two major players in Alzheimer's disease (AD), cause inhibitory interneuron impairments and aberrant neuronal activity in the hippocampal dentate gyrus in AD-related mouse models and humans, leading to learning and memory deficits. To determine whether replacing the lost or impaired interneurons rescues neuronal signaling and behavioral deficits, we transplanted embryonic interneuron progenitors into the hippocampal hilus of aged apoE4 knock-in mice without or with Aß accumulation. In both conditions, the transplanted cells developed into mature interneurons, functionally integrated into the hippocampal circuitry, and restored normal learning and memory. Thus, restricted hilar transplantation of inhibitory interneurons restores normal cognitive function in two widely used AD-related mouse models, highlighting the importance of interneuron impairments in AD pathogenesis and the potential of cell replacement therapy for AD. More broadly, it demonstrates that excitatory and inhibitory balance are crucial for learning and memory, and suggests an avenue for investigating the processes of learning and memory and their alterations in healthy aging and diseases.

RESUMO

The prescribing of antibiotics for uncomplicated skin abscesses and diverticulitis has no benefit. Some antibiotics are more at risk of causing a Clostridium difficile infection. The tests used to exclude a history of a penicillin allergy are safe. A threshold of D-dimer adjusted for the age significantly improves the specificity of the test without affecting the sensitivity. The prescription of paraclinics tests is not an effective "treatment" for the patient's anxiety. In the sleep apnea syndrome, treatment with CPAP (Continuous positive airway pressure) appears to have more benefits compared to the mandibular advancement prosthesis. The work of primary care physicians can be supported by the work of advanced practice nurses. The limitation placed on the working hours of doctors in hospitals seems to affect their ability to spend time with their patients.

RESUMO

BACKGROUND: Due to the nature of their work, general practitioners (GPs) need to be up to date with evidence in various medical domains. While much synthesised research evidence is easily accessible nowadays, in practice, the time to search for and review this evidence proposes a challenge. In German primary care, the knowledge infrastructure is rather fragmented, leaving GPs with relatively few primary care specific resources of information and many resources from other medical fields. This study aimed to explore GPs information-seeking behaviour regarding evidence-based recommendations in cardiovascular care in Germany. METHODS: To explore views of GPs a qualitative research design was chosen. Data was collected through semi-structured interviews. In total, 27 telephone interviews with GPs were conducted between June and November 2021.Verbatim transcript interviews were then analysed using thematic analysis, deriving at themes inductively. RESULTS: Two broad strategies of information-seeking behaviour in GP could be distinguished: (a) generic information-seeking behaviour and (b) casuistic information-seeking. The first referring to strategies GPs apply to keep up with medical developments such as new medication and the second referring to purposeful information exchange regarding individual patients, such as referral letters. The second strategy was also used to keep up with medical developments in general. CONCLUSION: In a fragmented information landscape, GPs used information exchange on individual patients to remain informed about medical developments in general. Initiatives to implement recommended practices need to take this into account, either by using these sources of influence or by making GPs aware of possible bias and risks. The findings also emphasize the importance of systematic evidence-based sources of information for GPs. TRAIL REGISTRATION: We registered the study prospectively on 07/11/2019 at the German Clinical Trials Register (DRKS, www.drks.de ) under ID no. DRKS00019219.

RESUMO

Introduction: A wide range of factors influence coordination and continuity of care. The aim of this study was to explore how management continuity of cardiovascular-related ambulatory care is influenced by the following network characteristics: presence of a case coordinator, network reciprocity, network composition and team climate. Methods: This cross-sectional observational study included three written surveys. The primary outcome management continuity of cardiovascular care was measured with the team/cross-boundary scale in the Nijmegen Continuity Questionnaire. The final analysis comprised a multivariate linear multilevel model with the predictors: presence of a case coordinator, network reciprocity, network composition and team climate. Results: Eighteen general practices with 83 health workers and 340 patients participated. The linear multilevel regression analysis showed a positive influence of team climate on cross-boundary continuity of care (b-coefficient 0.44, 95% confidence interval 0.09-0.78, p = 0.02). No statistically significant influence was measured for the other predictors. Discussion: To improve integrated care, therefore, emphasis should also be placed on promoting the team climate within individual practices. Regarding network characteristics, further research is needed, especially in larger practices. Conclusion: This study showed that team climate had an independent, relevant and statistically significant association with cross-boundary continuity of cardiovascular ambulatory care.

RESUMO

Background: Hospital readmission rates are very high in patients with chronic obstructive pulmonary disease (COPD). Continuity of care (CoC) with general practitioners (GPs) and ambulatory specialists can impact readmission rates. This study aimed to identify shared patient networks of ambulatory care physicians and to examine the effect of provider connectedness on CoC and hospital readmissions. Methods: A retrospective observational study was conducted in claims data from the years 2016 to 2018 in patients with COPD (aged 40 years or older; hospital stay in 2017). Linkages between GPs, pneumologists, and cardiologists were determined on the basis of shared patients. Multilevel regression models were used to analyze the impact of provider connectedness, operationalized by several social network characteristics, on continuity of care (sequential continuity [SECON] index) and hospital readmission rates. Results: A total of 7294 patients linked to 3673 GPs were available for analysis. Closeness centrality (ß=- 0.029) and the external-internal (EI)-index (ß =0.037) impacted on the SECON index. The EI-index (odds ratio [OR]=1.25) and degree centrality (OR=1.257) impacted 30-day readmission. Network density (OR=0.811) and the SECON index (OR=1.121) affected the likelihood of a 90-day readmission. None of the predictors had a significant impact on 180-day and 365-day readmissions. Conclusions: Ambulatory care providers' connectedness showed some effects on hospital readmissions and CoC in patients with COPD up to 90 days after hospital discharge, but the additional predictive power is limited.

RESUMO

Background and objective: Obtaining informed consent in neonatal emergency research is challenging. The aim of this study was to assess parental perceptions of informed consent following participation in a clinical trial in neonatal emergency care. Methods: This was a supplementary analysis of a randomised controlled trial comparing video and direct laryngoscopy for neonatal endotracheal intubation in the delivery room and neonatal intensive care unit. After obtaining informed consent for the clinical trial, parents were asked to answer a series of self-administered questions about their perceptions of clinical trial participation and the consent process. Informed consent had been given either before birth, after birth but before inclusion in the trial, or after inclusion in the trial. Results: We received responses from 33 mothers and 27 fathers (n = 60) of the 63 preterm and term infants who participated in the study. Fifty-three (89.8%, n = 59) parents agreed that infants should participate in clinical trials, and 51 (85%, n = 60) parents agreed that parents should be asked for informed consent. Fifty-three (89.8%, n = 59) parents felt that their infant's participation in this particular trial would be beneficial. Fifty-two (86.7%, n = 60) parents felt that the informed consent process was satisfactory. One parent (100%, n = 1) approached before birth, 23 parents (82.1%, n = 28) approached after birth but before enrolment and 26 (83.9%, n = 31) parents approached after enrolment were satisfied with the timing of the consent process. Eight (13.3%, n = 60) parents felt some pressure to provide informed consent. Of these, two (25%) were approached before enrolment and six (75%) were approached after enrolment. Conclusion: Parents valued their infant's participation in an emergency neonatal clinical trial and considered it important to be asked for consent. In this study, it seemed less important whether consent was obtained before or after the intervention. Future studies may need to investigate which form of consent is most acceptable to parents for the individual study in question.

RESUMO

BACKGROUND: Interprofessional training wards (IPTW) can contribute to the development of interprofessional competencies. In order to evaluate the acquisition of competencies, instruments are needed that record both team performance and individual competencies in the clinical teaching setting in third-party assessment. This paper describes the Interprofessional Ward Round Individual and Team Assessment-Tool, IP-VITA ("Interprofessionelle Visiten Individual und Team Assessment Tool") and its development. METHOD: Based on the empirical exploration of the three observation instruments "Teamwork Assessment Scale" (TAS), "McMaster-Ottawa Scale" and "Individual Teamwork Observation and Feedback Tool" (iTOFT) in at least four rounds each at the HIPSTA (with n=8 students and trainees each), a preliminary version of the IP-VITA was created. This preliminary version was then refined in subsequent empirical steps: a consensual validation in the research team was followed by a "member check" with the clinical colleagues of the HIPSTA, the input from external experts and an empirical test in an alternative setting. RESULTS: The IP-VITA is an empirically developed multimodal instrument to assess the interprofessional competencies of trainees and students as well as their team performance in clinical settings with patient interaction. It comprises three parts. In part A, structural data, the persons involved and the essential patient characteristics are recorded. Part B consists of 12 items and a free-text field for recording behaviour at the individual level. Part C also consists of 12 items and evaluates behaviour at team level. DISCUSSION: The IP-VITA instrument was developed specifically for the context of evaluating interprofessional ward rounds in a clinical educational setting. The instrument takes into account the ambiguous position of the assessment of interprofessional collaboration between individual competence and team performance. Beyond the HIPSTA, it can be used as a formative assessment instrument, and it may also be useful for summative assessments.
