ABSTRACT
In silico clinical trials (ISCTs) are an emerging method in modeling and simulation where medical interventions are evaluated using computational models of patients. ISCTs have the potential to provide cost-effective, time-efficient, and ethically favorable alternatives for evaluating the safety and effectiveness of medical devices. However, ensuring the credibility of ISCT results is a significant challenge. This paper aims to identify unique considerations for assessing the credibility of ISCTs and proposes an ISCT credibility assessment workflow based on recently published model assessment frameworks. First, we review various ISCTs described in the literature, carefully selected to showcase the range of methodological options available. These studies cover a wide variety of devices, reasons for conducting ISCTs, patient model generation approaches including subject-specific versus 'synthetic' virtual patients, complexity levels of devices and patient models, incorporation of clinician or clinical outcome models, and methods for integrating ISCT results with real-world clinical trials. We next discuss how verification, validation, and uncertainty quantification apply to ISCTs, considering the range of ISCT approaches identified. Based on our analysis, we then present a hierarchical workflow for assessing ISCT credibility, using a general credibility assessment framework recently published by the FDA's Center for Devices and Radiological Health. Overall, this work aims to promote standardization in ISCTs and contribute to the wider adoption and acceptance of ISCTs as a reliable tool for evaluating medical devices.

Manufacturers of medical devices are legally required to carry out post-market surveillance and respond to any on-market complaints they receive about their device. When it comes to addressing use issues experienced on market, manufacturers often focus on revising the instructions for use (IFU) and labeling. One of the challenges with this approach is the potential need to re-validate via a human factors validation study, without knowing whether the changes made will be effective in addressing the identified issues. With populations becoming increasingly technically literate, there is now great potential to rethink the way we can support self-injection through digital and web-based tools. This paper introduces the potential of digital instructions to improve the user experience of self-injection and address known use issues, as well as the challenges of incorporating them in medical device design.

BACKGROUND: The reporting of adverse events (AEs) relating to medical devices is a long-standing area of concern, with suboptimal reporting due to a range of factors including a failure to recognize the association of AEs with medical devices, lack of knowledge of how to report AEs, and a general culture of nonreporting. The introduction of artificial intelligence as a medical device (AIaMD) requires a robust safety monitoring environment that recognizes both generic risks of a medical device and some of the increasingly recognized risks of AIaMD (such as algorithmic bias). There is an urgent need to understand the limitations of current AE reporting systems and explore potential mechanisms for how AEs could be detected, attributed, and reported with a view to improving the early detection of safety signals. OBJECTIVE: The systematic review outlined in this protocol aims to yield insights into the frequency and severity of AEs while characterizing the events using existing regulatory guidance. METHODS: Publicly accessible AE databases will be searched to identify AE reports for AIaMD. Scoping searches have identified 3 regulatory territories for which public access to AE reports is provided: the United States, the United Kingdom, and Australia. AEs will be included for analysis if an artificial intelligence (AI) medical device is involved. Software as a medical device without AI is not within the scope of this review. Data extraction will be conducted using a data extraction tool designed for this review and will be done independently by AUK and a second reviewer. Descriptive analysis will be conducted to identify the types of AEs being reported, and their frequency, for different types of AIaMD. AEs will be analyzed and characterized according to existing regulatory guidance. RESULTS: Scoping searches are being conducted with screening to begin in April 2024. Data extraction and synthesis will commence in May 2024, with planned completion by August 2024. The review will highlight the types of AEs being reported for different types of AI medical devices and where the gaps are. It is anticipated that there will be particularly low rates of reporting for indirect harms associated with AIaMD. CONCLUSIONS: To our knowledge, this will be the first systematic review of 3 different regulatory sources reporting AEs associated with AIaMD. The review will focus on real-world evidence, which brings certain limitations, compounded by the opacity of regulatory databases generally. The review will outline the characteristics and frequency of AEs reported for AIaMD and help regulators and policy makers to continue developing robust safety monitoring processes.

It is well accepted that medical devices (MDs) and procedures have several unique characteristics compared with pharmaceuticals, such as learning curve (LC), incremental innovation (II), dynamic pricing (DP), and organizational impact (OI). The objective of this study was to determine the extent to which these MD characteristics are routinely assessed by health technology assessment (HTA) agencies and incorporated in their guidelines and reports. Three approaches were taken. First, a review of the most recent HTA methods guidelines from 14 selected HTA agencies and 5 HTA networks was undertaken. Next, HTA reports from these agencies were reviewed for inclusion of MD-specific characteristics for 16 selected MDs. Finally, a narrative literature review on this topic was conducted. A total of 13 of the included HTA organizations, and some HTA networks (2/5), have published either general or MD-specific method guidelines, whilst several addressed MD-specific characteristics. NICE included all four MD characteristics in their guidelines, but this did not equate to their inclusion in published HTA evaluations. European Network HTA (EUnetHTA) described the inclusion of LC (within patient safety) and OI within their guidance. The results highlight a lack of consistency. For the narrative review, 10/149 articles identified were reviewed. Most provided recommendations on challenges faced by HTAs, proposed steps to address uncertainties around MD characteristics and reported a lack of methodological guidance for evaluating MDs. A lack of inclusion of MD characteristics in HTA is a complex interplay of several important factors. For these characteristics to become a formal part of HTA of MDs in the future, clear guidance and frameworks are required to enable manufacturers to develop appropriate evidence, and HTA practitioners to assess their impact more broadly.

BACKGROUND: Artificial intelligence (AI) medical devices have the potential to transform existing clinical workflows and ultimately improve patient outcomes. AI medical devices have shown potential for a range of clinical tasks such as diagnostics, prognostics, and therapeutic decision-making such as drug dosing. There is, however, an urgent need to ensure that these technologies remain safe for all populations. Recent literature demonstrates the need for rigorous performance error analysis to identify issues such as algorithmic encoding of spurious correlations (eg, protected characteristics) or specific failure modes that may lead to patient harm. Guidelines for reporting on studies that evaluate AI medical devices require the mention of performance error analysis; however, there is still a lack of understanding around how performance errors should be analyzed in clinical studies, and what harms authors should aim to detect and report. OBJECTIVE: This systematic review will assess the frequency and severity of AI errors and adverse events (AEs) in randomized controlled trials (RCTs) investigating AI medical devices as interventions in clinical settings. The review will also explore how performance errors are analyzed including whether the analysis includes the investigation of subgroup-level outcomes. METHODS: This systematic review will identify and select RCTs assessing AI medical devices. Search strategies will be deployed in MEDLINE (Ovid), Embase (Ovid), Cochrane CENTRAL, and clinical trial registries to identify relevant papers. RCTs identified in bibliographic databases will be cross-referenced with clinical trial registries. The primary outcomes of interest are the frequency and severity of AI errors, patient harms, and reported AEs. Quality assessment of RCTs will be based on version 2 of the Cochrane risk-of-bias tool (RoB2). Data analysis will include a comparison of error rates and patient harms between study arms, and a meta-analysis of the rates of patient harm in control versus intervention arms will be conducted if appropriate. RESULTS: The project was registered on PROSPERO in February 2023. Preliminary searches have been completed and the search strategy has been designed in consultation with an information specialist and methodologist. Title and abstract screening started in September 2023. Full-text screening is ongoing and data collection and analysis began in April 2024. CONCLUSIONS: Evaluations of AI medical devices have shown promising results; however, reporting of studies has been variable. Detection, analysis, and reporting of performance errors and patient harms is vital to robustly assess the safety of AI medical devices in RCTs. Scoping searches have illustrated that the reporting of harms is variable, often with no mention of AEs. The findings of this systematic review will identify the frequency and severity of AI performance errors and patient harms and generate insights into how errors should be analyzed to account for both overall and subgroup performance.

The regulation of medical devices and In Vitro Diagnostic (IVD) medical devices have lagged significantly, especially in low- and middle-income countries. Disparities in regulating medical and IVD medical devices in Africa are below the global average. This may translate to poor access to quality-assured medical and IVD devices, resulting in undesirable health outcomes. Operational readiness to regulate medical and IVD devices at the Medicines Control Authority of Zimbabwe (MCAZ) was assessed. The aim was to determine the strengths and gaps and propose an action plan that can be monitored and evaluated to assess progress over time. We used the World Health Organization (WHO) Global Benchmarking Tool for medical devices and IVDs methodology to evaluate regulatory oversight of these products. Purposive sampling was used for data collection using researcher-administered global benchmarking tool factsheets and document reviews to evaluate the implementation of the regulatory functions. The regulatory functions assessed were the National Regulatory System, Registration and Market Authorization, Vigilance, Market Surveillance and Control, Licensing Establishment, Regulatory Inspection, Laboratory Testing, and Clinical Trials Oversight. The MCAZ attained maturity level 1, with a regulatory system score of 79%, registration and market authorization 44%, vigilance 27%, market surveillance and control 40%, licensing establishment 62%, regulatory inspection 68%, laboratory testing 88%, and clinical trials 18%. Condoms and gloves were the only regulated medical devices in Zimbabwe. IVDs were not regulated by the MCAZ. This review showed that the regulatory system is not robust, fit for purpose, responsive, transparent, or proportionate to the risk classification of medical devices and IVDs. It is crucial to amend the Medicines and Allied Substance Control Act to incorporate the definition and classification of medical devices and IVDs, regulatory authority establishment, licensing and registration, quality management system, conformity assessment, post-market surveillance, labeling and instructions for use, capacity building and training, and international harmonization.

Medical devices and In Vitro Diagnostics (IVDs) are vital for public health and accessible healthcare. Still, there is an imbalance in high-quality products in Low and Middle-Income Countries (LMICs). Zimbabwe's regulatory framework for medical devices and IVDs is unclear, leading to ineffective compliance and surveillance. As a result, there are knowledge gaps regarding pre-market and post-market regulatory elements to ensure the safety, quality and performance of medical devices and IVDs used in Zimbabwe. Our study aimed to explore the current status of medical devices and IVD regulations in Zimbabwe. Semi-structured interviews were conducted with 12 regulators from the Medicines Control Authority of Zimbabwe (MCAZ) National Microbiology Reference Laboratory (NMRL), Medical Laboratory and Clinical Scientists Council (MLCScCZ) to understand the current status of medical devices and IVD regulations in Zimbabwe. Three participants completed a questionnaire to understand the regulatory landscape in Zimbabwe. Three key informant interviews were conducted with three regulators from the South African Health Products Regulatory Authority (SAHPRA), Tanzanian Medicines and Medical Devices Authority (TMDA), and World Health Organization Regulatory Systems Strengthening (WHO RSS) to learn best practices to create a roadmap for Zimbabwe. We analyzed qualitative data using a thematic analysis. The findings reveal significant deficiencies and gaps in the legal framework for regulating medical devices and IVDs, highlighting the need for a legal framework and the absence of more comprehensive regulations. Regulatory entities face capacity limitations, especially in regulating medical devices and IVDs. Conformity assessment processes, medical devices, IVD classification criteria, and post-market surveillance also represent challenges, highlighting the need for a well-defined framework and regulatory procedures. The Zimbabwean regulatory system pathway is reactive, prompting several regulatory initiatives to address needs. Despite facing challenges, there is recognition of the importance of collaboration among regulatory authorities, emphasizing a shared commitment to improving and strengthening medical devices and IVD regulations for improved patient safety. By advocating for a proactive, comprehensive, and legally sound approach, indicating the potential for collaboration and synergy, this study provides a foundation for well-informed policy recommendations to guide enhancements and build a framework for a resilient, efficient, and transparent regulatory environment in the Zimbabwe and African regions as a whole.

INTRODUCTION: Half of the hospital-acquired pressure ulcers are associated with the use of medical devices. Nursing students provide care services to patients in clinical settings and intensive care units who have or are at risk for medical device-related pressure ulcers (MDRPUs). In the prevention and care of MDRPUs, the attitudes of nursing students towards preventing of pressure ulcers are as crucial as their knowledge level and clinical skills. AIM: The aim of this descriptive study is to assess the attitudes of final-year nursing undergraduate students towards preventing MDRPUs across cognitive, affective, and behavioral dimensions of ABC model. MATERIALS AND METHODS: Data of the study was handed between April 1 and December 31, 2021, with 147 final-year nursing students. Data were collected using the Student Information Form and the Attitude Towards Preventing Medical Device-Related Pressure Ulcers Questionnaire (ATP-MDRPUsQ). RESULTS: The mean attitude score towards preventing MDRPUs was 3.98 ± 0.45 on a 5-point Likert scale. The mean scores for the cognitive, affective, and behavioral sub-dimensions were 3.88 ± 0.57, 4.15 ± 0.51, and 4.00 ± 0.672, respectively. A moderate positive relationship was found between the cognitive sub-dimension and both the affective and behavioral sub-dimensions (r = 0.451; r = 0.302; p < 0.01, respectively). Based on cluster analysis, the mean attitude scores of students towards MDRPU prevention were grouped into two clusters. The students in Cluster-2 and female students had higher mean attitude scores (p < 0.01). The item with the lowest mean score in the questionnaire pertained to the item, "I believe that I need training on the etiology and prevention of medical device-related pressure ulcers." CONCLUSION: The general attitudes of final-year nursing students towards prevention MDRPU were satisfactory. However, their cognitive attitudes were less positive compared to their affective and behavioral attitudes. It is recommended to incorporate theoretical and practical courses focusing on the prevention of these injuries into nursing curricula to enhance students' knowledge and attitudes.

BACKGROUND: Artificial intelligence (AI)-based medical devices have garnered attention due to their ability to revolutionize medicine. Their health technology assessment framework is lacking. OBJECTIVE: This study aims to analyze the suitability of each health technology assessment (HTA) domain for the assessment of AI-based medical devices. METHODS: We conducted a scoping literature review following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) methodology. We searched databases (PubMed, Embase, and Cochrane Library), gray literature, and HTA agency websites. RESULTS: A total of 10.1% (78/775) of the references were included. Data quality and integration are vital aspects to consider when describing and assessing the technical characteristics of AI-based medical devices during an HTA process. When it comes to implementing specialized HTA for AI-based medical devices, several practical challenges and potential barriers could be highlighted and should be taken into account (AI technological evolution timeline, data requirements, complexity and transparency, clinical validation and safety requirements, regulatory and ethical considerations, and economic evaluation). CONCLUSIONS: The adaptation of the HTA process through a methodological framework for AI-based medical devices enhances the comparability of results across different evaluations and jurisdictions. By defining the necessary expertise, the framework supports the development of a skilled workforce capable of conducting robust and reliable HTAs of AI-based medical devices. A comprehensive adapted HTA framework for AI-based medical devices can provide valuable insights into the effectiveness, cost-effectiveness, and societal impact of AI-based medical devices, guiding their responsible implementation and maximizing their benefits for patients and health care systems.

Chemical equivalence testing can be used to assess the biocompatibility implications of a materials or manufacturing change for a medical device. This testing can provide a relatively facile means to evaluate whether the change may result in additional or different toxicological concerns. However, one of the major challenges in the interpretation of chemical equivalence data is the lack established criteria for determining if two sets of extractables data are effectively equivalent. To address this gap, we propose a two-part approach based upon a relatively simple statistical model. First, the probability of a false positive conclusion, wherein there is an incorrectly perceived increase for a given analyte in the comparator relative to the baseline device, can be reduced to a prescribed level by establishing an appropriate acceptance criterion for the ratio of the observed means. Second, the probability of a false negative conclusion, where an actual increase in a given analyte cannot be discerned from the test results, can be minimized by specifying a limiting value of applicability based on the margin of safety (MoS) of the analyte. This approach provides a quantitative, statistically motivated method to interpret chemical equivalence data, despite the relatively high intrinsic variability and small number of replicates typically associated with a chemical characterization evaluation.

Novel medical devices must conform to medical device regulation (MDR) for European market entry. Likewise, chemicals must comply with the Registration, Evaluation, Authorization and Restriction of Chemicals (REACh) regulation. Both pose regulatory challenges for manufacturers, but concordantly provide an approach for transferring data from an already registered device or compound to the one undergoing accreditation. This is called equivalence for medical devices and read-across for chemicals. Although read-across is not explicitly prohibited in the process of medical device accreditation, it is usually not performed due to a lack of guidance and acceptance criteria from the authorities. Nonetheless, a scientifically justified read-across of material-based endpoints, as well as toxicological assessment of chemical aspects, such as extractables and leachables, can prevent failure of MDR device equivalence if data is lacking. Further, read-across, if applied correctly can facilitate the standard MDR conformity assessment. The need for read-across within medical device registration should let authorities to reconsider device accreditation and the formulation of respective guidance documents. Acceptance criteria like in the European Chemicals Agency (ECHA) read-across assessment framework (RAAF) are needed. This can reduce the impact of the MDR and help with keeping high European innovation device rate, beneficial for medical device patients.

OBJECTIVES: Our objective was to explore procedures and methods used at health technology assessment (HTA) agencies for assessing medical devices and the underlying views of HTA practitioners about appropriate methodology to identify challenges in adopting new methodologies for assessing devices. We focused on the role of normative commitments of HTA practitioners in the adoption of new methods. METHODS: An online survey, including questions on procedures, scoping, and assessments of medical devices, was sent to members of the International Network of Agencies for Health Technology Assessment. Interviews were conducted with survey respondents and HTA practitioners involved in assessments of transcatheter aortic valve implantation to gain an in-depth understanding of choices made and views about assessing medical devices. Survey and interview questions were inspired by the "values in doing assessments of health technologies" approach towards HTA, which states that HTA addresses value-laden questions and information. RESULTS: The current practice of assessing medical devices at HTA agencies is predominantly based on procedures, methods, and epistemological principles developed for assessments of drugs. Both practical factors (available time, demands of decision-makers, existing legal frameworks, and HTA guidelines), as well as commitments of HTA practitioners to principles of evidence-based medicine, make the adoption of a new methodology difficult. CONCLUSIONS: There is a broad recognition that assessments of medical devices may need changes in HTA methodology. In order to realize this, the HTA community may require both a discussion on the role, responsibility, and goals of HTA, and resulting changes in institutional context to adopt new methodologies.

The aim of this integrative review was to explore the effect of care bundles in the prevention of Medical Device Related Pressure Ulcers (MDRPU). An MDRPU is a wound that occurs on the skin or mucosal membranes because of pressure or pressure in combination with shear. Like other types of pressure ulcers, they will have negative consequences for patients and healthcare organisations alike. Many MDRPU's are preventable. A literature search was undertaken from computerised databases using key search terms, Pressure Ulcer* Pressure Injur* and Medical Device*. Databases included CINAHL; Medline and SocIndex. A total of seven studies were found that met the criteria for inclusion in this review. When compared to the widely recognised and trusted international guidelines there was variation found between the individual interventions selected within each study for inclusion within the bundle. Skin assessment and device repositioning were the most frequently included interventions in the bundles, followed by use of prophylactic dressings, appropriate device selection and fitting. The least common intervention was monitoring the tension of the device and/or its securements. All studies reported a reduction in the number of MDRPU's when care bundles were used in clinical practice. However, there is variation in bundle designs and study methodologies employed. This review has demonstrated the potential benefit of care bundles in reducing MDRPU. However, due to heterogeneity in the study methods employed and the interventions within the care bundles, further, more robust research is required to establish which interventions show the most clinical and patient benefit.

BACKGROUND: Treatment and care of patients in intensive care units require the use of many medical and technological instruments. Pressure injuries occur when medical devices, which are used more in intensive care patients and are in direct or indirect contact with the skin, cause focal and localized forces on the superficial or deep tissues. OBJECTIVE: In this study, it was aimed to examine the risk factors, incidence and characteristics of medical device-related pressure injuries in intensive care patients. METHODS: This study has a prospective and descriptive design. The study was carried out in the adult intensive care unit of a healthcare institution located in the western Turkey. 138 intensive care patients treated in the level 3 adult intensive care unit were enrolled in the study. The first observations and evaluations of intensive care patients in terms of pressure injuries were made within the first 24 h after admission to the clinic. Observations continued daily during the hospitalization period of the patient. Data were collected with the Intensive Care Patient Information Form, Glasgow Coma Scale, Braden Pressure Ulcer Risk Assessment Scale and Identification Form for Medical device-related Pressure Ulcers. Analysis of data was performed with descriptive statistical methods, Shapiro-Wilk Test, Mann-Whitney U Test and Chi-Square analysis. RESULTS: Medical device-related pressure injury developed in 11.6% (n = 16) of intensive care patients. Anatomically, pressure injury occurred most frequently on the lip (37.5%) and most frequently due to the intubation tube (37.5%). Most of the developed wounds (75.0%) were found to be stage 2. Multinominal logistic regression analysis, which was performed to determine the effect of independent variables on medical device-related pressure injuries in intensive care patients, was found to be statistically significant (X2 = 37.098, p < 0.001). When the regression coefficients were examined, it was found that total hospitalization time in the intensive care unit (ß = 0.948, p < 0.01) and PaCO2 level (ß = 0.923, p < 0.01) had a positive, and duration of aerobic respiration with nasal cannula or mask (ß = -0.920, p < 0.01) and Braden score (ß = -0.948, p < 0.01) had a negative and significant effect on medical device-related pressure injuries. CONCLUSIONS: In this study found that the MDRPIs development rate was lower than other studies. It was observed that pressure injuries due to medical devices developed more frequently in patients with longer hospitalization days, higher PaCO2 levels, shorter duration of oxygenated breathing with nasal cannula or mask, and lower Braden scores.
