Revised European Association for Palliative Care (EAPC) recommended framework on palliative sedation: An international Delphi study.

BACKGROUND: The European Association for Palliative Care (EAPC) acknowledges palliative sedation as an important, broadly accepted intervention for patients with life-limiting disease experiencing refractory symptoms. The EAPC therefore developed 2009 a framework on palliative sedation. A revision was needed due to new evidence from literature, ongoing debate and criticism of methodology, terminology and applicability. AIM: To provide evidence- and consensus-based guidance on palliative sedation for healthcare professionals involved in end-of-life care, for medical associations and health policy decision-makers. DESIGN: Revision between June 2020 and September 2022 of the 2009 framework using a literature update and a Delphi procedure. SETTING: European. PARTICIPANTS: International experts on palliative sedation (identified through literature search and nomination by national palliative care associations) and a European patient organisation. RESULTS: A framework with 42 statements for which high or very high level of consensus was reached. Terminology is defined more precisely with the terms suffering used to encompass distressing physical and psychological symptoms as well as existential suffering and refractory to describe the untreatable (healthcare professionals) and intolerable (patient) nature of the suffering. The principle of proportionality is introduced in the definition of palliative sedation. No specific period of remaining life expectancy is defined, based on the principles of refractoriness of suffering, proportionality and independent decision-making for hydration. Patient autonomy is emphasised. A stepwise pharmacological approach and a guidance on hydration decision-making are provided. CONCLUSIONS: This is the first framework on palliative sedation using a strict consensus methodology. It should serve as comprehensive and soundly developed information for healthcare professionals.

Depressive-Like Effects of Foreclosing: A Cross-Sectional Study of Hair Cortisol Concentration.

INTRODUCTION: Foreclosing and home eviction have been associated with various negative health outcomes, probably due to exposure to such stressful circumstance, but there is no evidence about foreclosure and home eviction to elicit cortisol responses. METHODS: Participants who recently had received a court eviction notice were compared to subjects suffering a depressive disorder and to healthy controls in terms of hair cortisol concentrations. RESULTS: Subjects under the stressful circumstance of foreclosure and patients with depression showed comparable concentrations in most of the hair segments while healthy subjects displayed the lowest levels of cortisol. CONCLUSION: The findings show that foreclosure and home eviction are associated with increased cumulative hair cortisol and with depressive-like symptoms. Foreclosing procedures yielded to maintain high levels of cortisol which may increase the risk to develop major depression.

Soft Tissue Contours at Pontic Sites With or Without Soft Tissue Grafting-A 15-Year Follow-Up of a Controlled Clinical Study.

OBJECTIVES: To report on soft tissue contour changes at pontic sites with or without soft tissue grafting over an observation period of 15 years. METHODS: Fourteen patients received a fixed dental prosthesis (FDP) in the posterior zone in a controlled clinical study and were available at the 15-year follow-up. Eight patients received a subepithelial connective tissue graft in the pontic area (test) while six received the FDP without soft tissue grafting (control). Impressions were taken after FDP cementation and at 15 years. Casts were digitized and a profilometric analysis was performed (mean distance) and the pontic height (PH) and ridge width (RW) were analyzed at the mid-buccal area. A descriptive analysis and Wilcoxon-Mann-Whitney test was performed (level of significance: 5%). RESULTS: Profilometric changes (mean distance) from baseline to 15 years amounted to -0.68 mm (test) and to -0.33 mm (control) (p = 0.208), 95% CI for group difference (0.290; -0.750). PH measured -0.47 mm (test) and 0.0 mm (control) (p = 0.079) and RW amounted to -1.05 mm (test) and -0.38 mm (control) (p = 0.138). CONCLUSION: Remodeling of the soft tissue contour at pontic sites of FDPs was evident in both groups, but slightly more accentuated following soft tissue grafting. CLINICAL SIGNIFICANCE: This study is the first to report on soft tissue changes at pontic sites over more than 10 years. It investigates whether tissue contour changes with and without soft tissue grafting before the insertion of FDPs. Remodeling of the soft tissue contour at pontic sites was observed over 15 years, with more pronounced changes when soft tissues were augmented with SCTGs before FDP insertion. The volume loss at the augmented site must be considered in relation to the overall tissue changes over long periods. Connective tissue grafts reliably improve shape and esthetics around the pontic unit. Further long-term studies with more patients are needed to evaluate the initial gains and long-term performance of these augmentations.

Evaluation and assessment of the survival of tooth implant supported prosthesis in tooth and implant supported rehabilitation cases with metal frameworks.

INTRODUCTION: Over the years, implant therapy has been a commonly used treatment option for individuals who are partially or totally edentulous, with a long-term success rate of over 90%. With significant advancements in biomaterials and technology, implant dentistry can now conduct prosthetic rehabilitations in the majority of patients catering to all types of needs. However, in order to meet the demands of a patient base that is always growing, new trends in implantology are emerging in recent years that are focused on minimally invasive surgery and financial sustainability. In certain clinical scenarios, connecting teeth and implants to support fixed partial prosthesis (FPPs) may be a predictable and workable course of treatment. MATERIALS AND METHODS: 22 patients were selected for this study who had tooth and implant supported prosthesis placed as a final restoration. Out of these 22 patients; 12 were male and 10 were female patients. Implants were placed following proper protocol and if grafting procedures were required they were carried out. A second stage surgical procedure was carried out and delayed loading protocols were followed. The statistical analysis was done using the IBM SPSS 24.0, Chicago, USA. The survival of the implants and teeth were measured by the Kaplan Meier survival scale. Bone loss was assessed at baseline(upon loading), 12 months and 24 months. RESULTS: The implant survival rate was measured at 6 months, 12 months, 18 months and 24 months. At 24 months, one implant showed failure, so the survival rate of the implants were 95.4%. Bone loss of 1 mm was seen around one implant at 12 months. Bone loss of 1 and 2 mm was present around two implants and one implant respectively at 24 months. CONCLUSION: From the results of this study, we can conclude that tooth implant supported prosthesis show very good survival when used in rehabilitation cases.

Switch-maintenance avelumab immunotherapy following first-line chemotherapy for patients with advanced, unresectable or metastatic urothelial carcinoma: the first Japanese real-world evidence from a multicenter study.

OBJECTIVE: To develop the first Japanese real-world evidence of switch-maintenance avelumab in advanced, unresectable or metastatic urothelial carcinoma (aUC). METHODS: A multicenter-derived database registered 505 patients diagnosed with aUC between 2008 and 2021. Of these, 204 patients (40%) were selected and stratified according to the type of therapy used: maintenance avelumab group (27 [5.3%]), second-line (2 L) pembrolizumab group (103 [20%]) and 2 L cytotoxic chemotherapy group (74 [15%]). The progression-free survival and overall survival from the initiation of following therapy were compared. Tumor response was evaluated based on the Response Evaluation Criteria in Solid Tumors guideline v1.1 during the treatment period. A detailed analysis was performed in the maintenance avelumab group to investigate possible factors associated with response to avelumab therapy. RESULTS: The maintenance avelumab group had a longer overall survival, not progression-free survival, compared with the other two treatment groups. The median treatment-free interval between the last dose of first-line (1 L) chemotherapy and the initiation of avelumab therapy was 6 weeks (range, 3-22). Disease control rate of maintenance avelumab therapy in patients with a treatment-free interval of ≤6 weeks was higher than that in patients with a treatment-free interval of >6 weeks (77 vs 40%, P = 0.029). The patients showing objective response to 1 L chemotherapy were less likely to experience tumor relapse (4 of 19) after the initiation of avelumab therapy compared with those showing stable disease (7 of 8). CONCLUSIONS: Objective response to 1 L chemotherapy and early induction of maintenance avelumab therapy may be associated with increased benefit from maintenance avelumab therapy.

Heart rate variability behavior in athletes after a sports concussion: A systematic review.

OBJECTIVE: This systematic review aims to investigate the adaptations of the autonomic nervous system (ANS) after a concussion by measuring HRV in athletes over the age of 16 after injury. METHODS: This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). Web of Science, Pubmed, SCOPUS, and Sport Discus were searched using predefined search terms to identify relevant original cross-sectional, longitudinal, and cohort epidemiological studies published before December 2021. RESULTS: After screening 1737 potential articles, four studies met the inclusion criteria. Studies included participants with concussion (n = 63) and healthy control athletes (n = 140) who practised different sports. Two studies describe a decrease in HRV following a sports concussion, and one proposed that the resolution of symptoms does not necessarily reflect ANS recovery. Lastly, one study concluded that submaximal exercise induces alteration in ANS, not seen in rest after an injury. CONCLUSIONS: In the frequency domain, a decrease in high frequency power and an increase of low frequency/high frequency ratio is expected, as the activity of the sympathetic nervous system increases, and the parasympathetic nervous system decreases after injury. In the frequency domain, heart rate variability (HRV) may help monitor the activity of ANS evaluating signals of somatic tissue distress and early identification of other types of musculoskeletal injuries. Further research should investigate the relationship between HRV and other musculoskeletal injuries.

Effects of remote ear-nose-and-throat specialist assessment screening on self-reported hearing aid benefit and satisfaction.

OBJECTIVE: To explore the impact of remote versus in-person ear-nose-and-throat (ENT) specialist screening before hearing treatment on self-reported hearing aid (HA) benefit and satisfaction among adult first-time HA users. DESIGN: Participants were randomised to either remote or in-person ENT assessment before treatment initiation. Hearing ability, hearing quality, and treatment satisfaction were assessed pre- and post-HA treatment using the SSQ12, IOI-HA, and selected items from the 2021 Danish national Patient-Reported Experience Measures. Average daily HA usage was also recorded. STUDY SAMPLE: 751 adult potential first-time HA users with self-reported hearing impairment were included; 501 participants were remotely assessed in private or public audiological clinics, and 250 control group participants were assessed in-person by private ENT specialists. Of the 658 participants who completed the entire trial, 454 received HAs. RESULTS: No significant post-treatment HA benefit differences were found between groups. Remotely assessed HA recipients in private clinics expressed slightly higher staff and waiting time satisfaction. Participants with normal hearing and mild/moderate hearing loss reported higher pre-treatment hearing ability and quality. No significant difference in average daily HA usage was observed between groups. CONCLUSIONS: Findings suggest that remote screening does not compromise patient-reported HA benefit and satisfaction when compared to in-person screening.

Rebleeding in peptic ulcer bleeding - a nationwide cohort study of 19,537 patients.

BACKGROUND: Rebleeding is a frequent complication of peptic ulcer bleeding (PUB). The associated prognosis remains rather unclear because previous studies generally also included non-ulcer lesions. OBJECTIVE: We aimed to identify predictors for rebleeding; clarify the prognostic consequence of rebleeding; and develop a score for predicting rebleeding. METHODS: Nationwide cohort study of consecutive patients presenting to hospital with PUB in Denmark from 2006-2014. Logistic regression analyses were used to identify predictors for rebleeding, evaluate the association between rebleeding and 30-day mortality, and develop a score to predict rebleeding. Patients with persistent bleeding were excluded. RESULTS: Among 19,258 patients (mean age 74 years, mean ASA-score 2.4), 10.8% rebled, and 10.2% died. Strongest predictors for rebleeding were endoscopic high-risk stigmata of bleeding (Odds Ratio (OR): 2.12 [95% Confidence Interval (CI): 1.91-2.36]), bleeding from duodenal ulcers (OR: 1.87 [95% CI: 1.69-2.08]), and presentation with hemodynamic instability (OR: 1.55 [95% CI: 1.38-1.73]). Among patients with all three factors (7.9% of total), 24% rebled, 50% with rebleeding failed endoscopic therapy, and 23% died. Rebleeding was associated with increased mortality (OR: 2.04 [95% CI: 1.78-2.32]). We were unable to develop an accurate score to predict rebleeding. CONCLUSION: Rebleeding occurs in ∼10% of patients with PUB and is overall associated with a two-fold increase in 30-day mortality. Patients with hemodynamic instability, duodenal ulcers, and high-risk endoscopic stigmata are at highest risk of rebleeding. When rebleeding occurs in such patients, consultation with surgery and/or interventional radiology should be obtained prior to repeat endoscopy.

A probabilistic model for co-occurrence analysis in bibliometrics.

The co-occurrence analysis of Medical Subject Heading (MeSH) terms extracted from the PubMed database is popularly used in bibliometrics. Practically for making the result interpretable, it is necessary to apply a certain filter procedure of co-occurrence matrix for removing the low-frequency items due to their low representativeness. Unfortunately, there is rare research referring to determine a critical threshold to remove the noise of co-occurrence matrix. Here, we proposed a probabilistic model for co-occurrence analysis that can provide statistical inferences about whether the paired items co-occur randomly. With help of this model, the dimensionality of co-occurrence matrix could be reduced according to the selected threshold. The conceptual model framework, simulation and practical applications are illustrated in the manuscript. Further details (including all reproducible codes) can be downloaded from the project website: https://github.com/xizhou/co-occurrence-analysis.git.

Hypotension develops one to two hours before other symptoms in peptic ulcer rebleeding; a matched cohort study.

BACKGROUND: Rebleeding is a frequent complication of peptic ulcer bleeding (PUB) and is associated with increased mortality. Blood pressure and heart rate are two easy non-invasive measurements to evaluate the hemodynamics and therefore a standard observation during hospitalization. OBJECTIVE: We aimed to investigate the dynamics of systolic blood pressure and heart rate up to time of peptic ulcer rebleeding. DESIGN: Retrospective matched cohort study. Hemodynamics in patients with peptic ulcer rebleeding was compared to hemodynamics in a matched control group consisting of patients with PUB without rebleeding. Blood pressure and heart rate in the six hours up to diagnosis of rebleeding was compared with baseline in the case cohort as well as with the matched control group. RESULTS: Thirty-eight patients with peptic ulcer rebleeding and 66 controls were included. Mean age was 75 years, 62% were males and 30-day mortality was 23%. Baseline systolic blood pressure in cases was 114 mmHg. Compared to baseline, we found significant decrease in systolic blood pressure two hours before rebleeding (4 mmHg; p = 0.041) and one hour before rebleeding (14 mmHg; p = 0.0002). Mean systolic blood pressure 30 min before rebleeding was 89 mmHg. No significant change was found in heart rate (p = 0.99). In the control group no change was found in systolic blood pressure or heart rate. CONCLUSION: In patients with peptic ulcer rebleeding, hypotension develops 1-2 h before other symptoms of rebleeding. Thus, close monitoring of blood pressure is needed in order to ensure early identification of rebleeding in high-risk patients.

Insights into the social context of living with a dual diagnosis of HIV and cancer: a qualitative, thematic analysis of popular discourse in London newspapers.

As growing numbers of people living with HIV also develop cancer, a holistic understanding of their experiences is essential to the provision of patient centred care. Both conditions are linked to powerful beliefs in our society that may affect experiences. This study explored how HIV and cancer were represented in UK newspapers to gain insight into the social context of living with a dual diagnosis. We performed an initial content analysis of HIV articles and of cancer articles published in the free London newspapers, The Metro and The Evening Standard between 2012 and 2017, followed by qualitative thematic analysis and in-depth analysis of selected articles of exemplar cases. Both conditions were presented very differently. The underlying subtext was that cancer could happen to any of us. HIV was framed as a potentially dangerous, stigmatising phenomenon affecting "others". Popular discourse about HIV within news media remains largely negative and stigmatising. People living with a dual diagnosis of HIV and cancer may choose to prioritise the sharing of the more socially acceptable condition, cancer, in order to access support. The negotiation of cancer healthcare services is likely to be adversely influenced by the social burden of HIV related stigma.

Opening the door: midwives' perceptions of two models of psychosocial assessment in pregnancy- a mixed methods study.

BACKGROUND: One in five women experience psychological distress in the perinatal period. To support women appropriately, Australian guidelines recommend routine depression screening and psychosocial risk assessment by midwives in pregnancy. However, there is some evidence that current screening processes results in higher rates of false positives. The Perinatal Integrated Psychosocial Assessment (PIPA) Project compared two models of psychosocial assessment and referral - Usual Care and the PIPA model - with a view to improving referral decisions. This paper describes midwives' perspectives on psychosocial assessment, depression screening and referral at the antenatal booking appointment and compares midwives' experiences with, and perspectives on, the two models of care under investigation. METHODS: A two-phase, convergent mixed methods design was used. Midwives providing antenatal care completed a self-report survey in phase one prior to implementation of the new model of psychosocial assessment (n = 26) and again in phase two, following implementation (n = 27). Sixteen midwives also participated in two focus groups in phase two. Quantitative and qualitative data were compared and integrated in the presentation of results and interpretation of findings. RESULTS: Midwives supported psychosocial assessment believing it was a catalyst for 'Opening the door" to conversations with women. Midwives were comfortable asking the questions and tailored their approach to build rapport and trust. Overall. midwives expressed favourable views towards the PIPA model. A greater proportion of midwives relied mostly or entirely on the suggested wording for the psychosocial questions in the PIPA model compared to Usual Care (44.4% vs 12.0%, χ2=5.17, p=.023, φ =-.36). All midwives reported finding the referral or action message displayed at the end of the PIPA psychosocial assessment to be 'somewhat' or 'very' helpful, compared to 42.3% in Usual Care (χ2 = 18.36, p < .001, φ = -.64). Midwives were also more likely to act on or implement the message often or all of the time) in the PIPA model (PIPA = 69.2% vs Usual Care = 32.0%, (χ2 = 5.66, p < .017, φ = -.37). CONCLUSION: The study identified benefits of the new model and can inform improvements in psychosocial screening, referral and related care processes within maternity settings. The study demonstrates that psychosocial assessment can, over time, become normalised and embedded in practice.

Unchanged mortality in patients with acute cholangitis despite an increase in malignant etiologies - a 25-year epidemiological study.

Background and aims: Acute cholangitis (AC) is a rare but serious condition, with an incidence of 7.0 per 10,000 people and mortality rates up to 10%. The aim of this study was to describe changes in obstruction etiology, comorbidities, clinical factors, and mortality among AC patients during a 25-year period. Methods: Using a database of 11,563 consecutive ERCP-procedures performed from 1990-2015 at Odense University Hospital, we identified all AC cases during that period. Clinical and epidemiological data were collected from the database and the Danish Patient Registry. Association with 30-day mortality was investigated using multiple logistic regression analysis with adjustment for confounding factors. Results: In total, 775 consecutive and individual cases of AC were included. Among cases, 42% (n = 326) were of malignant etiology, with an increasing incidence over time (regression coefficient [95% CI]: 0.03 [0.01-0.04] per year; p = .01). Mean Charlson Comorbidity Index was 1.4, with an increase over time (regression coefficient [95% CI]: 0.04 [0.03-0.05] per year; p < .01). Malignant obstruction etiology was associated with 30-day mortality (OR [95% CI]: 1.11 [1.04-1.18]; p < .01). Overall 30-day mortality was 12% (n = 91). After adjustment for confounding factors, no significant changes in 30-day mortality were observed over time (OR [95% CI]: 1 [1-1.00]; p = .91 per year). Conclusion: Significant increases in the incidence of malignant obstruction etiology and severity of comorbidities among AC patients were observed during the study period. Despite those findings, 30-day mortality remained unchanged, potentially reflecting a general improvement in the management of AC.

Potentially inappropriate medications with risk of cardiovascular adverse events in the elderly: A systematic review of tools addressing inappropriate prescribing.

WHAT IS KNOWN AND OBJECTIVE: In the last decades, many lists have been developed to screen for inappropriate prescribing. However, information on which potentially inappropriate medications (PIMs) could increase the cardiovascular risk in the elderly is not objectively presented. This review aimed to identify and quantify those PIMs by extracting information from published PIM-lists. METHODS: In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement (PRISMA), a systematic review of PIM-lists was conducted. The search strategy was run in PubMed, MEDLINE and Google Scholar (1991-09/2017). All PIMs described in those lists were extracted and stratified by their potential cardiovascular risk (including major adverse cardiovascular events-MACE). The number of times each PIM was reported on those lists was also assessed. RESULTS AND DISCUSSION: We identified 724 papers, and 24 were retained. From those, a total of 17 PIMs to be avoided by the elderly and 21 drug-disease interactions were retrieved. The reporting of PIMs with risk of cardiovascular adverse events was 15.3%, whereas the reporting of those with MACE risk was 7.2%. PIMs most frequently described were tricyclic antidepressants (TCAs; 12/24), centrally acting antiadrenergic agents (11/24), NSAIDs (7/24), antiarrhythmics (Class I and III; 6/24), peripherally acting antiadrenergic agents (6/24) and antithrombotic agents (5/24). Most frequently described PIMs with MACE risk were NSAIDs (7/24), antiarrhythmics (Class I and III) (7/24), selective calcium channel blockers with vascular effects (6/24) and antipsychotics (4/24). WHAT IS NEW AND CONCLUSION: Data suggest that PIM-lists focus mainly on common adverse events and often poorly describe the potential consequence for MACE occurrence. This systematic review could help healthcare professionals in the identification and deprescribing of these medicines in older patients with high cardiovascular risk during medication review.

Esophageal endoscopic submucosal dissection using sodium hyaluronate is safe and effective.

BACKGROUND/AIMS: A submucosal cushion of sodium hyaluronate facilitates gastric and colorectal endoscopic submucosal dissection (ESD). However, few studies have evaluated the utility of sodium hyaluronate for ESD of esophageal lesions. The aim of this study is to evaluate the utility and safety of sodium hyaluronate for ESD of superficial esophageal squamous cell neoplasms (ESCN). MATERIAL AND METHODS: We retrospectively reviewed 111 ESCN in 86 patients treated by ESD between September 2007 and April 2013. There were four double cancers, with 107 ESD procedures analyzed. RESULTS: The en bloc resection rate was 99% (106/107). The R0 resection rate was 93% (99/107). Of 106 specimens resected en bloc, four specimens had a positive horizontal margin, two specimens had non-assessable horizontal margins and one specimen had non-assessable horizontal and vertical margins. One patient with a non-assessable horizontal margin developed local recurrence seven months later, treated by repeat ESD. Delayed bleeding occurred in two procedures (2%), and intra-procedural perforation occurred in four (4%). None required operative repair. Endoscopy trainees performed 33 of 107 (31%) ESD procedures. Post-ESD stenosis requiring dilation occurred following five procedures (5%). CONCLUSIONS: Sodium hyaluronate for ESD of ESCN achieves a high R0 resection rate with a low rate of adverse events.

Salmon Bias and Preterm Birth Among Western Immigrants in China.

Introduction Immigrants from Western industrialized countries are rarely found in immigrant studies. Our primary objective was to calculate the rate of cesarean delivery, 5-min Apgar score <7, and preterm birth among Chinese and Western women. Our secondary objective was to examine whether there are significant differences in terms of risk factors between Western immigrants who chose to deliver in their country of citizenship compared to those who chose to deliver in China. Methods Single-center retrospective cohort study in Shanghai, China. Multivariate logistic regression models used delivery outcome, and place of delivery (China vs. country of citizenship) as outcome variables. Results Preterm birth occurred at a rate of 3.82% among Chinese citizens, 4.12% among Chinese-born Western citizens, and 6.54% among non-Chinese-born Western citizens. After adjustment, preterm birth <37 weeks was more frequent among non-Chinese-born Western citizens compared with Chinese citizens, with an odds ratio of 1.82 (Confidence Interval 1.20-2.78), p = 0.005. Variables statistically associated with giving birth in China were maternal age ≥35 years and being Chinese-born Western, as well as the absence of medical or obstetrical conditions. Discussion Western immigrants have overall good obstetrical outcomes in China, and this could be partly explained by selective immigration, but also by the Salmon bias, as women with risk factors tend to return to their country of citizenship for the delivery. However, the preterm birth rate was higher among Western women than in their Chinese counterparts, and further research is needed.

Use of a structured functional evaluation process for independent medical evaluations of claimants presenting with disabling mental illness: rationale and design for a multi-center reliability study.

BACKGROUND: Work capacity evaluations by independent medical experts are widely used to inform insurers whether injured or ill workers are capable of engaging in competitive employment. In many countries, evaluation processes lack a clearly structured approach, standardized instruments, and an explicit focus on claimants' functional abilities. Evaluation of subjective complaints, such as mental illness, present additional challenges in the determination of work capacity. We have therefore developed a process for functional evaluation of claimants with mental disorders which complements usual psychiatric evaluation. Here we report the design of a study to measure the reliability of our approach in determining work capacity among patients with mental illness applying for disability benefits. METHODS/DESIGN: We will conduct a multi-center reliability study, in which 20 psychiatrists trained in our functional evaluation process will assess 30 claimants presenting with mental illness for eligibility to receive disability benefits [Reliability of Functional Evaluation in Psychiatry, RELY-study]. The functional evaluation process entails a five-step structured interview and a reporting instrument (Instrument of Functional Assessment in Psychiatry [IFAP]) to document the severity of work-related functional limitations. We will videotape all evaluations which will be viewed by three psychiatrists who will independently rate claimants' functional limitations. Our primary outcome measure is the evaluation of claimant's work capacity as a percentage (0 to 100 %), and our secondary outcomes are the 12 mental functions and 13 functional capacities assessed by the IFAP-instrument. Inter-rater reliability of four psychiatric experts will be explored using multilevel models to estimate the intraclass correlation coefficient (ICC). Additional analyses include subgroups according to mental disorder, the typicality of claimants, and claimant perceived fairness of the assessment process. DISCUSSION: We hypothesize that a structured functional approach will show moderate reliability (ICC ≥ 0.6) of psychiatric evaluation of work capacity. Enrollment of actual claimants with mental disorders referred for evaluation by disability/accident insurers will increase the external validity of our findings. Finding moderate levels of reliability, we will continue with a randomized trial to test the reliability of a structured functional approach versus evaluation-as-usual.

Antimicrobial surface coating in the emergency department as protective technology for infection control (ASEPTIC): a pilot randomized controlled trial.

STUDY OBJECTIVE: We examined the effectiveness of an antimicrobial surface coating for continual disinfection of high touch-frequency surfaces in the emergency department (ED). METHODS: Following a preliminary observation identifying stretcher rails as the surface with highest touch-frequency in the ED, we conducted a pilot randomized controlled trial involving 96 stretcher rails. The stretchers were randomized to receive an antimicrobial surface coating or placebo coating. Routine cleaning of stretchers subsequently continued as per hospital protocol in both arms. Sampling for total aerobic, gram-positive halophilic, gram-negative and methicillin-resistant Staphylococcus aureus bacteria was performed pre- and post-treatment at 24 h, 7 days and 180 days. Individuals who applied the coating and outcome assessors were blinded to the allocated arms. The primary outcome is contamination of antimicrobial versus placebo rails measured as colony forming units per cm2(CFU/cm2). RESULTS: Baseline total aerobic bacteria was comparable between placebo and intervention arms (0.84 versus 1.32 CFU/cm2, P = 0.235). Total aerobic bacteria contamination was significantly lower on antimicrobial versus placebo rails at 24 h (0.61 versus 1.01 CFU/cm2, median difference 0.40 CFU/cm2, 95% confidence interval [CI] 0.01 to 1.01 CFU/cm2). There was a non-statistically significant tendency for contamination to be lower on antimicrobial versus placebo rails at 7 days (1.15 versus 1.50 CFU/cm2, median difference 0.35 CFU/cm2, 95% CI -0.64 to 1.28 CFU/cm2), but higher at 180 days (2.06 versus 1.84 CFU/cm2, median difference - 0.22 CFU/cm2, 95% CI -1.19 to 0.78 CFU/cm2). CONCLUSION: This is the first double-blinded, placebo-controlled, randomized trial to evaluate an antimicrobial surface coating on high touch-frequency surfaces in the emergency department. Total aerobic bacteria found on antimicrobial-coated patient transport stretcher rails was significantly lower than placebo rails at 24 h.
