A Most Significant Change evaluation of a new co-designed tool to measure holistic well-being in consumers of community aged care services.

OBJECTIVES: To evaluate a Wellbeing Check-in tool and process for use with BlueCare's home care package (HCP) clients by care and well-being practitioners. The tool had been co-designed with HCP clients and trialled with 15 clients. METHODS: The Most Significant Change (MSC) methodology was used to gather stories from five practitioners, five HCP staff and seven clients. A workshop with senior staff was held to determine themes and whether the tool met its aims. RESULTS: Out of 22 MSC stories, 18 were judged in scope by workshop participants. Eight themes were then identified. Four themes reflected the content of the narratives (i.e. what was discussed): Isolation and connection; Grief; Faith/explicit spirituality; and Client preference. The other four themes reflected the process (i.e. what the discussions meant to participants): Being there/Meaningful conversations; Impact on significant others; New insight; and Purpose of the check-in. These eight themes largely reflected the aims of the Wellbeing Check-in tool in terms of providing a means to optimise connectedness, well-being and spiritual care in accordance with the client's needs, goals and preferences. Unanticipated findings included its benefits for family members and uncertainty about the aim or value of the tool, which highlighted the need for BlueCare to be clear about the purpose of the tool in promoting it to clients and their informal carers. CONCLUSIONS: The Wellbeing Check-in tool was found to be fit for purpose. A tool used flexibly to prompt discussion about well-being can be helpful to clients and pastoral care staff.

Leveraging Machine Learning to Develop Digital Engagement Phenotypes of Users in a Digital Diabetes Prevention Program: Evaluation Study.

BACKGROUND: Digital diabetes prevention programs (dDPPs) are effective "digital prescriptions" but have high attrition rates and program noncompletion. To address this, we developed a personalized automatic messaging system (PAMS) that leverages SMS text messaging and data integration into clinical workflows to increase dDPP engagement via enhanced patient-provider communication. Preliminary data showed positive results. However, further investigation is needed to determine how to optimize the tailoring of support technology such as PAMS based on a user's preferences to boost their dDPP engagement. OBJECTIVE: This study evaluates leveraging machine learning (ML) to develop digital engagement phenotypes of dDPP users and assess ML's accuracy in predicting engagement with dDPP activities. This research will be used in a PAMS optimization process to improve PAMS personalization by incorporating engagement prediction and digital phenotyping. This study aims (1) to prove the feasibility of using dDPP user-collected data to build an ML model that predicts engagement and contributes to identifying digital engagement phenotypes, (2) to describe methods for developing ML models with dDPP data sets and present preliminary results, and (3) to present preliminary data on user profiling based on ML model outputs. METHODS: Using the gradient-boosted forest model, we predicted engagement in 4 dDPP individual activities (physical activity, lessons, social activity, and weigh-ins) and general activity (engagement in any activity) based on previous short- and long-term activity in the app. The area under the receiver operating characteristic curve, the area under the precision-recall curve, and the Brier score metrics determined the performance of the model. Shapley values reflected the feature importance of the models and determined what variables informed user profiling through latent profile analysis. RESULTS: We developed 2 models using weekly and daily DPP data sets (328,821 and 704,242 records, respectively), which yielded predictive accuracies above 90%. Although both models were highly accurate, the daily model better fitted our research plan because it predicted daily changes in individual activities, which was crucial for creating the "digital phenotypes." To better understand the variables contributing to the model predictor, we calculated the Shapley values for both models to identify the features with the highest contribution to model fit; engagement with any activity in the dDPP in the last 7 days had the most predictive power. We profiled users with latent profile analysis after 2 weeks of engagement (Bayesian information criterion=-3222.46) with the dDPP and identified 6 profiles of users, including those with high engagement, minimal engagement, and attrition. CONCLUSIONS: Preliminary results demonstrate that applying ML methods with predicting power is an acceptable mechanism to tailor and optimize messaging interventions to support patient engagement and adherence to digital prescriptions. The results enable future optimization of our existing messaging platform and expansion of this methodology to other clinical domains.

The prevention school diary: Evaluability assessment of a widely adopted intervention in Ile-de-France.

OBJECTIVES: The prevention school diary is distributed each year to children aged between 10 and 11 years old by La Ligue contre le cancer, a French association promoting prevention and research against cancer. While they write their homework in the diary, children can learn about a range of health determinants. This diary promotes health in a fun and educational way, as it integrates drawings made by children about the different themes covered by the diary. This paper aims to present the evaluability assessment of this intervention in Ile-de-France (Paris area), where it is already widely deployed. MATERIAL AND METHODS: We have traced the history of the prevention school diary and assessed how it is currently used in Ile-de-France by leading interviews with county committees of La Ligue contre le cancer. Successive versions of the diary and results of teacher satisfaction surveys were examined. All information collected was integrated into a logic model, which characterizes the main components, actors, and effects of the intervention. RESULTS: The prevention school diary was created in the West of France in the late 90s. It was then implemented in Paris and extended to other counties of Ile-de-France. Currently, six counties collaborate on the production of a common diary. Whereas it only dealt with tobacco consumption at the beginning, the prevention school diary now covers nutrition, physical activity, sun exposure, sleep and screen use, addiction, as well as safety in some counties. Three levels of intervention have been identified, depending on whether or not the distribution of the diary is followed by the production of drawings for the next edition or health education sessions. The expected effects of the prevention school diary have been integrated into a logic model emphasizing children, school, and family level. Outcomes include Capabilities (knowledge and skills), Opportunities, and Motivation to adopt healthy Behaviours, according to the theoretical model of behaviour change COM-B. CONCLUSION: The evaluability assessment phase enabled us to gain a better understanding of the conditions under which the intervention is deployed, and thus to identify the factors to be considered for a broad assessment of its effectiveness. It is especially important since the intervention is already well established in Ile-de-France.

Feasibility and Acceptability of a Health App Platform Providing Individuals With a Budget to Purchase Preselected Apps to Work on Their Health and Well-Being: Quantitative Evaluation Study.

BACKGROUND: The potential of health apps for health promotion and disease prevention is widely recognized. However, uptake is limited due to barriers individuals face in finding suitable and trustworthy apps, such as the overwhelming amount of available health apps. Therefore, the health app platform "FitKnip" was developed, enabling individuals to purchase preselected, trustworthy health apps with a budget of 100 euros (a currency exchange rate of EUR €1=US $1.0831 is applicable). The platform aimed to empower individuals to improve their health and vitality, ultimately supporting a more healthy society. OBJECTIVE: The primary aim of this study was to evaluate the health app platform in terms of feasibility and acceptability. Potential effects on health empowerment and health outcomes were secondarily explored. METHODS: This quantitative study was part of a mixed methods study with a prospective pre-post interventional design. We collected web-based user data, and self-reported web-based questionnaires were collected over 5 measurements over an 8-month period. Use statistics were tracked on the platform, including the number of purchased apps and euros spent per user registered within the health app platform. We measured the user-friendliness of the health app platform using the System Usability Scale (SUS) and satisfaction using the Client Satisfaction Questionnaire-8 (CSQ-8) and several 10-point Likert items. We asked participants to indicate, on a scale from 1 (not at all) to 10 (completely), how much the health app platform contributed to various areas related to health empowerment. We assessed health-related quality of life by the 12-item Short-Form Health Survey (SF-12) and one's perceived level of stress by the 10-item Perceived Stress Scale (PSS-10). RESULTS: A total of 1650 participants were included, of whom 42% (685/1650) bought at least 1 app. The majority of those purchased one app (244/685, 35.6%). The health app platform was rated as user-friendly (SUS mean 66.5, SD 20.7; range 66.5-70.0), and the acceptability of the health app platform was moderate (CSQ-8 mean 20.0, SD 1.5; range 19.6-20.0). Results furthermore showed that participants were generally satisfied to highly satisfied with the ease of the payment system to purchase apps on the platform (median 8, IQR 7-10), the look and feel of the platform (median 7, IQR 6-8), as well as the provided budget of 100 euros (median 9, IQR 7-10). Participants were less satisfied with the amount (median 6, IQR 4-7) and diversity (median 6, IQR 4-7) of apps offered on the platform. CONCLUSIONS: A health app platform is a promising initiative to enhance public health. Feasibility and acceptability are critical for success, as they ensure that such a platform is accessible, user-friendly, and meets end users' needs and preferences. This can help to increase uptake, engagement, and ultimately the platform's adoption and effectiveness.

Patient and Public Involvement and Engagement in the Development of a Platform Clinical Trial for Parkinson's Disease: An Evaluation Protocol.

Background: Patient and public involvement and engagement (PPIE) in the design of trials is important, as participant experience critically impacts delivery. The Edmond J Safra Accelerating Clinical Trials in PD (EJS ACT-PD) initiative is a UK consortium designing a platform trial for disease modifying therapies in PD. Objective: The integration of PPIE in all aspects of trial design and its evaluation throughout the project. Methods: PwP and care partners were recruited to a PPIE working group (WG) via UK Parkinson's charities, investigator patient groups and participants of a Delphi study on trial design. They are supported by charity representatives, trial delivery experts, researchers and core project team members. PPIE is fully embedded within the consortium's five other WGs and steering group. The group's terms of reference, processes for effective working and PPIE evaluation were co-developed with PPIE contributors. Results: 11 PwP and 4 care partners have supported the PPIE WG and contributed to the development of processes for effective working. A mixed methods research-in-action study is ongoing to evaluate PPIE within the consortium. This includes the Patient Engagement in Research Scale -a quantitative PPIE quality measure; semi-structured interviews -identifying areas for improvement and overall impressions of involvement; process fidelity- recording adherence; project documentation review - identifying impact of PPIE on project outputs. Conclusions: We provide a practical example of PPIE in complex projects. Evaluating feasibility, experiences and impact of PPIE involvement in EJS ACT-PD will inform similar programs on effective strategies. This will help enable future patient-centered research.

Evaluating a Future-Oriented Positive Youth Development Intervention to Reduce Sexual Risk Among Highly Mobile Youth: Results and Challenges.

PURPOSE: Youth experiencing or at risk of experiencing homelessness need tailored prevention programming to prevent unplanned pregnancy and sexually transmitted infections. This study evaluated the efficacy of a small-group, future-oriented positive youth development (PYD) intervention to reduce sexual risk behaviors. METHOD: Youth aged 14-19 (n = 483) experiencing or at risk of experiencing homelessness were recruited at youth-serving agencies and in alternative schools. Each cohort enrolled was randomized either to a 10-session, 5-week group future-oriented intervention to support them in adopting health-promoting behaviors such as using contraception, including condom use (n = 244) or to a no-treatment condition where they received usual services/schooling (n = 239). We assessed at baseline and 3-month and 9-month follow-up (1) vaginal intercourse without consistent contraception use, (2) vaginal and anal intercourse without consistent condom use, and (3) sexual risk behaviors, including current (last 3 months) effective contraception use by females who did not report current use at baseline. RESULTS: There was no significant difference between treatment and control conditions for most outcomes. However, among females not currently using contraception at baseline, 34% in the treatment condition compared to 12.9% in the control condition reported using contraception in the 3 months before the 9-month survey, a statistically significant difference. DISCUSSION: This sexual risk reduction intervention, grounded in PYD theory and tailored to address the needs of marginalized groups of youth, demonstrated efficacy at increasing contraceptive uptake among females. The need for PYD interventions that can be delivered in a variety of nontraditional school and service settings are discussed.

[Dementia Care Nurses in the networked care of people with dementia: a qualitative evaluation study]. / Dementia Care Nurses in der vernetzten Versorgung von Menschen mit Demenz.

Dementia Care Nurses in the networked care of people with dementia: A qualitative evaluation study Abstract: Background: To coordinate networked dementia care counselling concepts with case management (CM) structures are recommended. This approach has been explored and evaluated within the Dementia Care Nurse project in Saxony-Anhalt. Studies on the implementation of CM are mostly limited to cooperation between case managers and medical and nursing professional groups. Networking processes with all stakeholders involved in dementia care have hardly been described so far. Objective: The aim was to describe the experienced collaboration with Dementia Care Nurses (DCNs) from the perspective of the participating cooperation partners and to derive approaches for the continuation of the DCNs in routine care. Method: Eight semi-structured interviews were conducted with cooperation partners from the health and social care sector who participated in the DCN project. The interviews were analysed for content. Results: The interviews were evaluated by content analysis. Results: Overall, the interviewed cooperation partners rated the collaboration with the DCNs in the project as positive, especially the proactive approach and the continuous support of people with dementia. The continuation in routine care depends on the institutional location and the qualification of the DCNs. Conclusion: The commitment of DCNs enables a more demand-oriented involvement of relevant stakeholders in the individual planning of dementia care.

Public Dental Service Access Policies for People with Autism Spectrum Disorder (ASD) in Salvador, Bahia, Brazil: A Pre-Evaluation Study.

This study sought to carry out a systematic and preliminary evaluation of the policies on access to public dental services for people with ASD in a Brazilian city. The study, conducted between November/2019 and February/2020, was developed through document analysis, the design of the theoretical logical model of the policies, and seven semi-structured interviews with key informants. The sample was intentionally selected. We also considered the answers to 108 questionnaires from a pilot study on the access of people with ASD to dental services applied to caregivers, dentists, and non-dental professionals. No refusals were recorded. The availability study showed that the policies' objectives were not being achieved in terms of care network organization: there were no institutional flows, personal contacts were used between professionals to guarantee access to secondary attention, there was no specific training for the dentists about ASD, and the oral health care network was unknown to non-dentist professionals and caregivers. Most people with ASD have visited the dentist at least once in their lives, but a large percentage of those within this study did not do so in the last year. This study identified difficulties in implementing policies and suggested possible strategies for overcoming them as dimensions and subdimensions for evaluation.

[Bedside-teaching on dementia and delirium: Development, implementation, and evaluation in an acute care hospital]. / Bedside-Teaching zum Thema Demenz und Delir.

Bedside-teaching on dementia and delirium: Development, implementation, and evaluation in an acute care hospital Abstract: Background: Demographic change and the accompanying increase in people with dementia and delirium in acute care hospitals pose growing challenges for nurses in acute care wards. Objective: Pilot implementation and evaluation of knowledge gain and implementation of previously defined critical behaviors. Method: Implementation of the training by APNs. Parallel evaluation of the training along the New World Kirkpatrick model using questionnaires and non-participant observation. Analysis of the data using descriptive statistics. Results: The training itself was well evaluated by the participants. It showed an increase in knowledge of the participants in the main topic categories. The targeted critical behaviors were implemented for the most part. There are deficiencies in the mapping of interventions in the nursing care process. Conclusion: The training concept is suitable to give nurses confidence in dealing with people with dementia and delirium. Continuous support in practice is needed to maintain the interventions in the long term and sustainably in everyday life.

Acceptance of Telepresence Robotics, Telecare and Teletherapy Among Stroke Patients, Relatives and Therapy Staff.

BACKGROUND: Stroke as a cause of disability in adulthood causes an increasing demand for therapy and care services, including telecare and teletherapy. OBJECTIVES: Aim of the study is to analyse the acceptance of telepresence robotics and digital therapy applications. METHODS: Longitudinal study with a before and after survey of patients, relatives and care and therapy staff. RESULTS: Acceptance of the technology analysed is high in all three groups. Although acceptance among patients declined in parts of the cases in the second survey after having used telerobotics, all in all approval ratings remained high. With regard to patients no significant correlation was found between the general technology acceptance and the acceptance of use of telerobotics. CONCLUSION: Accepted new telecare and teletherapies can be offered with the help of telepresence robotics. This requires knowledge of and experience with the technology.

Novel Approach for Detecting Respiratory Syncytial Virus in Pediatric Patients Using Machine Learning Models Based on Patient-Reported Symptoms: Model Development and Validation Study.

BACKGROUND: Respiratory syncytial virus (RSV) affects children, causing serious infections, particularly in high-risk groups. Given the seasonality of RSV and the importance of rapid isolation of infected individuals, there is an urgent need for more efficient diagnostic methods to expedite this process. OBJECTIVE: This study aimed to investigate the performance of a machine learning model that leverages the temporal diversity of symptom onset for detecting RSV infections and elucidate its discriminatory ability. METHODS: The study was conducted in pediatric and emergency outpatient settings in Japan. We developed a detection model that remotely confirms RSV infection based on patient-reported symptom information obtained using a structured electronic template incorporating the differential points of skilled pediatricians. An extreme gradient boosting-based machine learning model was developed using the data of 4174 patients aged ≤24 months who underwent RSV rapid antigen testing. These patients visited either the pediatric or emergency department of Yokohama City Municipal Hospital between January 1, 2009, and December 31, 2015. The primary outcome was the diagnostic accuracy of the machine learning model for RSV infection, as determined by rapid antigen testing, measured using the area under the receiver operating characteristic curve. The clinical efficacy was evaluated by calculating the discriminative performance based on the number of days elapsed since the onset of the first symptom and exclusion rates based on thresholds of reasonable sensitivity and specificity. RESULTS: Our model demonstrated an area under the receiver operating characteristic curve of 0.811 (95% CI 0.784-0.833) with good calibration and 0.746 (95% CI 0.694-0.794) for patients within 3 days of onset. It accurately captured the temporal evolution of symptoms; based on adjusted thresholds equivalent to those of a rapid antigen test, our model predicted that 6.9% (95% CI 5.4%-8.5%) of patients in the entire cohort would be positive and 68.7% (95% CI 65.4%-71.9%) would be negative. Our model could eliminate the need for additional testing in approximately three-quarters of all patients. CONCLUSIONS: Our model may facilitate the immediate detection of RSV infection in outpatient settings and, potentially, in home environments. This approach could streamline the diagnostic process, reduce discomfort caused by invasive tests in children, and allow rapid implementation of appropriate treatments and isolation at home. The findings underscore the potential of machine learning in augmenting clinical decision-making in the early detection of RSV infection.

The Purpose of Internet Use and Face-To-Face Communication With Friends and Acquaintances Among Older Adults: A JAGES Longitudinal Study.

Internet use influences social interactions in society. However, there is no consensus on whether and what kind of Internet use increases face-to-face communication (FFC). This study investigated the mode of Internet use that increases FFC among older adults after three years. Participants were 8734 adults aged 65 or older who responded to the Japan Gerontological Evaluation Study (JAGES) surveys in 2016 and 2019. The exposures were the purposes of Internet use in 2016. The outcome was the frequency of FFC with friends or acquaintances in 2019. The confounders included 13 demographic, socioeconomic, and psychological variables. We performed modified Poisson regression analyses and found that Internet use for communication in 2016 increased FFC in 2019, especially for low-frequency FFC in 2016. Internet-based non-FFC may help promote FFC and prevent social isolation among older adults who are less likely to interact with others.

Psychometric Evaluation of a Tablet-Based Tool to Detect Mild Cognitive Impairment in Older Adults: Mixed Methods Study.

BACKGROUND: With the rapid aging of the global population, the prevalence of mild cognitive impairment (MCI) and dementia is anticipated to surge worldwide. MCI serves as an intermediary stage between normal aging and dementia, necessitating more sensitive and effective screening tools for early identification and intervention. The BrainFx SCREEN is a novel digital tool designed to assess cognitive impairment. This study evaluated its efficacy as a screening tool for MCI in primary care settings, particularly in the context of an aging population and the growing integration of digital health solutions. OBJECTIVE: The primary objective was to assess the validity, reliability, and applicability of the BrainFx SCREEN (hereafter, the SCREEN) for MCI screening in a primary care context. We conducted an exploratory study comparing the SCREEN with an established screening tool, the Quick Mild Cognitive Impairment (Qmci) screen. METHODS: A concurrent mixed methods, prospective study using a quasi-experimental design was conducted with 147 participants from 5 primary care Family Health Teams (FHTs; characterized by multidisciplinary practice and capitated funding) across southwestern Ontario, Canada. Participants included health care practitioners, patients, and FHT administrative executives. Individuals aged ≥55 years with no history of MCI or diagnosis of dementia rostered in a participating FHT were eligible to participate. Participants were screened using both the SCREEN and Qmci. The study also incorporated the Geriatric Anxiety Scale-10 to assess general anxiety levels at each cognitive screening. The SCREEN's scoring was compared against that of the Qmci and the clinical judgment of health care professionals. Statistical analyses included sensitivity, specificity, internal consistency, and test-retest reliability assessments. RESULTS: The study found that the SCREEN's longer administration time and complex scoring algorithm, which is proprietary and unavailable for independent analysis, presented challenges. Its internal consistency, indicated by a Cronbach α of 0.63, was below the acceptable threshold. The test-retest reliability also showed limitations, with moderate intraclass correlation coefficient (0.54) and inadequate κ (0.15) values. Sensitivity and specificity were consistent (63.25% and 74.07%, respectively) between cross-tabulation and discrepant analysis. In addition, the study faced limitations due to its demographic skew (96/147, 65.3% female, well-educated participants), the absence of a comprehensive gold standard for MCI diagnosis, and financial constraints limiting the inclusion of confirmatory neuropsychological testing. CONCLUSIONS: The SCREEN, in its current form, does not meet the necessary criteria for an optimal MCI screening tool in primary care settings, primarily due to its longer administration time and lower reliability. As the number of digital health technologies increases and evolves, further testing and refinement of tools such as the SCREEN are essential to ensure their efficacy and reliability in real-world clinical settings. This study advocates for continued research in this rapidly advancing field to better serve the aging population. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): RR2-10.2196/25520.

Association between social support and ambulance use among older people in Japan: an empirical cross-sectional study.

BACKGROUND: Ambulance service demand and utilization are increasing worldwide. To address this issue, the factors that affect ambulance use must be identified. Few studies have examined factors that can intervene and thus reduce the frequency of ambulance use. This study aimed to examine the association between social support and ambulance use among older adults in Japan. We hypothesize that social support is associated with reduced ambulance use. METHODS: This cross-sectional study was conducted as part of the Japan Gerontological Evaluation Study. In December 2019 and January 2020, we collaborated with individuals aged 65 years or above with no long-term care needs. A total of 24,581 participants were included in the analysis. The objective and explanatory variables were ambulance use and social support, respectively. Binomial regression analysis was used to calculate the odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: Social support was associated with ambulance use. People who had no one to listen to their complaints or worries were significantly more likely to use ambulance services than those who did (OR [95% CI] = 1.26 [1.03-1.53]). People with no one to take care of them when they were ill were also significantly more likely to use ambulance services than those who had someone to provide care (1.15 [1.01-1.31]). Moreover, the results of binomial logistic regression analysis indicated that individuals who called an ambulance but were not hospitalized had significantly lower social support compared to those who did not call an ambulance. CONCLUSIONS: The results suggest that the presence and quality of social support play a significant role in ambulance use among older adults in Japan. Our findings can help policymakers to plan and implement strategies for reducing the burden on emergency medical care.

Protocol for identifying and characterising critical physical tasks in the military: Development and validation.

BACKGROUND: When establishing Physical Employment Standards, validity is dependent on the correct identification and characterisation of critical job tasks. OBJECTIVE: To develop and validate a standardised protocol for the identification, characterisation, and documentation of critical physical job tasks in military occupational specialities in the Swedish Armed Forces (SwAF), and propose a definition of critical physical job tasks for use in the SwAF. METHODS: A protocol was drafted with three content domains, including a preliminary definition. Protocol content validity was iteratively assessed in two consecutive stages where ten subject experts rated relevance and simplicity. A consensus panel revised the protocol after each stage. Content validity index (CVI) was calculated as item-CVI (I-CVI) per each feature and as scale average (S-CVI/Ave) per content domain. Acceptable content validity thresholds were 0.78 and 0.90, respectively. RESULTS: The validated protocol consisted of 35 items with an I-CVI≥0.90 and≥0.80 for relevance and simplicity, respectively. The S-CVI/Ave was 0.97 for relevance and 0.98 for simplicity. The protocol was language reviewed, reorganised for easy use, and approved by the consensus panel. The final protocol includes: background and aim of the protocol, the accepted generic and critical physical job task definitions, protocol instructions, subject expert-qualifications, job task source and characteristics. CONCLUSION: A standardised protocol for identification and characterisation of critical job tasks in SwAF military occupational specialties was developed. The protocol content was rated relevant and simple by experts and will be of importance in future work establishing physical requirements in the SwAF.

Affordable blood culture systems from China: in vitro evaluation for use in resource-limited settings.

BACKGROUND: Bloodstream infections (BSI) pose a significant threat due to high mortality rates and the challenges posed by antimicrobial resistance (AMR). In 2019, an estimated 4.95 million deaths were linked to bacterial AMR. The highest impact was seen in resource-limited settings (RLS). For diagnosis of BSI, performant continuously-monitoring blood culture systems (CMBCS) have been optimized. However, in RLS, the implementation of CMBCS is hindered by budget constraints and unsuitable environmental conditions. Manufacturers from growing economies are currently producing affordable in vitro diagnostics, which could fill the gap in capacity, but so far these are not established outside their domestic markets. METHODS: This study evaluated the performance, usability, and interchangeability of Chinese CMBCS in a laboratory setting using simulated blood cultures with a panel of 20 BSI-associated strains. Four systems were selected for the assessment: Autobio BC60, Mindray TDR60, Scenker Labstar50, and DL-biotech DL-60. FINDINGS: Overall, all evaluated CMBCS demonstrated good performance with high yield (96.7-100%) and specificity (97.5-100%), comparable to the reference system (bioMérieux 3D). In addition, when used as "manual" blood cultures in a conventional incubator with visual growth detection, performance was also satisfactory: yield was between 90 and 100% and specificity was 100% for all BCBs. Both the CMBCS and the BCBs were easy to use and lot-to-lot variability in BCBs was minimal. The interchangeability testing indicated that the BCBs from different brands (all except Scenker) were compatible with the various automates, further highlighting the potential for a harmonized "universal BCB." INTERPRETATION: Based on this in vitro study, we recommend the use of these systems in settings with challenging environments and limited resources. The Autobio system performed best for automatic detection and DL-Biotech BCBs for manual cultures respectively (combination of performance, price, usability). The appropriateness for use in RLS should still be confirmed in a field study. FUNDING: The study was funded by FIND.

The development and evaluation of a medication diary to report problems with medication use.

Purpose: The study aimed to develop and evaluate a medication diary for patients to report problems with medication use to enable shared-decision making and improve medication adherence. Methods: Based on a search for existing diaries, a review of the content, and a list of medication self-management problems compiled from previous research, a paper and pencil version of a medication diary was developed. The diary was reviewed for clarity and overall presentation by five healthcare providers and nine patients. Afterwards, user-friendliness was evaluated by 69 patients with polypharmacy discharged from hospital during a quantitative prospective study. Results: The medication diary consists of several parts: (1) a medication schedule allowing patients to list their medicines, (2) information sheets allowing patients to write down specific medication-related information, (3) a monthly overview to indicate daily whether medication-related problems were experienced, (4) problem sheets elaborating on the problems encountered, (5) space for specific medication-related questions for healthcare providers to facilitate shared-decision making. The review phase resulted in minor textual adjustments and one extra problem in the problem sheet. Most participants, who tested the medication diary for two months, found the diary user-friendly (80%) and easy to fill in (89%). About 40% of participants reported problems with medication use. Half of the patients indicated that the diary can facilitate discussing problems with healthcare providers. Conclusion: The medication diary offers patients the opportunity to report problems regarding their medication use in a proven user-friendly manner and to discuss these problems with healthcare providers. Reporting and discussing problems with medication use can serve as a first step towards making shared decisions on how to address the problems encountered.

Intraoperative Laparoscopic Hyperspectral Imaging during Esophagectomy-A Pilot Study Evaluating Esophagogastric Perfusion at the Anastomotic Sites.

Hyperspectral imaging (HSI) is a non-invasive and contactless technique that enables the real-time acquisition of comprehensive information on tissue within the surgical field. In this pilot study, we investigated whether a new HSI system for minimally-invasive surgery, TIVITA® Mini (HSI-MIS), provides reliable insights into tissue perfusion of the proximal and distal esophagogastric anastomotic sites during 21 laparoscopic/thoracoscopic or robotic Ivor Lewis esophagectomies of patients with cancer to minimize the risk of dreaded anastomotic insufficiency. In this pioneering investigation, physiological tissue parameters were derived from HSI measurements of the proximal site of the anastomosis (esophageal stump) and the distal site of the anastomosis (tip of the gastric conduit) during the thoracic phase of the procedure. Tissue oxygenation (StO2), Near Infrared Perfusion Index (NIR-PI), and Tissue Water Index (TWI) showed similar median values at both anastomotic sites. Significant differences were observed only for NIR-PI (median: 76.5 vs. 63.9; p = 0.012) at the distal site (gastric conduit) compared to our previous study using an HSI system for open surgery. For all 21 patients, reliable and informative measurements were attainable, confirming the feasibility of HSI-MIS to assess anastomotic viability. Further studies on the added benefit of this new technique aiming to reduce anastomotic insufficiency are warranted.

Meta-research: How many diagnostic or prognostic models published in radiological journals are evaluated externally?

OBJECTIVES: Prognostic and diagnostic models must work in their intended clinical setting, proven via "external evaluation", preferably by authors uninvolved with model development. By systematic review, we determined the proportion of models published in high-impact radiological journals that are evaluated subsequently. METHODS: We hand-searched three radiological journals for multivariable diagnostic/prognostic models 2013-2015 inclusive, developed using regression. We assessed completeness of data presentation to allow subsequent external evaluation. We then searched literature to August 2022 to identify external evaluations of these index models. RESULTS: We identified 98 index studies (73 prognostic; 25 diagnostic) describing 145 models. Only 15 (15%) index studies presented an evaluation (two external). No model was updated. Only 20 (20%) studies presented a model equation. Just 7 (15%) studies developing Cox models presented a risk table, and just 4 (9%) presented the baseline hazard. Two (4%) studies developing non-Cox models presented the intercept. Just 20 (20%) articles presented a Kaplan-Meier curve of the final model. The 98 index studies attracted 4224 citations (including 559 self-citations), median 28 per study. We identified just six (6%) subsequent external evaluations of an index model, five of which were external evaluations by researchers uninvolved with model development, and from a different institution. CONCLUSIONS: Very few prognostic or diagnostic models published in radiological literature are evaluated externally, suggesting wasted research effort and resources. Authors' published models should present data sufficient to allow external evaluation by others. To achieve clinical utility, researchers should concentrate on model evaluation and updating rather than continual redevelopment. CLINICAL RELEVANCE STATEMENT: The large majority of prognostic and diagnostic models published in high-impact radiological journals are never evaluated. It would be more efficient for researchers to evaluate existing models rather than practice continual redevelopment. KEY POINTS: • Systematic review of highly cited radiological literature identified few diagnostic or prognostic models that were evaluated subsequently by researchers uninvolved with the original model. • Published radiological models frequently omit important information necessary for others to perform an external evaluation: Only 20% of studies presented a model equation or nomogram. • A large proportion of research citing published models focuses on redevelopment and ignores evaluation and updating, which would be a more efficient use of research resources.

Changes in pain, daily occupations, lifestyle, and health following an occupational therapy lifestyle intervention: a secondary analysis from a feasibility study in patients with chronic high-impact pain.

OBJECTIVES: This study explored changes in pain-related parameters, occupational function, occupational balance, lifestyle factors, and self-perceived health status in adults with chronic high-impact pain participating in an occupational therapy lifestyle intervention. METHODS: This one-group longitudinal feasibility study was performed in three continuous feasibility rounds. The occupational therapists-led intervention targeted meaningful occupations, regular physical activity, and a healthy diet. The intervention contained individual and group sessions and was added to the standard multidisciplinary chronic pain treatment. Outpatients (n=40, 85 % females, 46.6 ± 10.9 years old) participated in the study between April 2019 and December 2021. The analysis includes data for 31 participants. Analysis of pre-post changes assessed after each feasibility round were performed for the outcomes: pain intensity, pain sensitivity and pain modulation (pressure pain threshold and tolerance, temporal summation of pain and conditioned pain modulation), pain self-efficacy, pain catastrophizing, motor and process skills, occupational balance, daily wake-time movement, daily walking steps, body mass index, waist circumference, blood pressure, and self-perceived health status. RESULTS: Improvements in motor skills (assessment of motor and process skills score=0.20 (1.37; 1.57), 95 % CI 0.01; 0.38) and temporal summation of pain (-1.19 (2.86; -1.67), 95 % CI -2.16; -0.22), but a decrease in pain tolerance (-7.110 (54.42; 47.32), 95 % CI -13.99; -0.22) were observed. Correlation analysis suggested moderate-to-very strong statistically significant relationships in several outcomes related to pain, health, pain coping, occupational balance, occupational functioning, body anthropometrics, and pain sensitivity. CONCLUSIONS: This study suggested that the lifestyle intervention would benefit motor skills while effects on other outcomes were unclear in adults with chronic pain. To confirm the findings, a randomized trial evaluating effectiveness is needed. Ethical committee number: SJ-307 Reg. Clinicaltrials.gov: NCT03903900.
