Defining the clinician's role in early health technology assessment during medical device innovation - a systematic review

A study on the formative usability testing for modular powered wheelchair

The increasing prevalence of mobility impairments underscores the urgent need for accessible and affordable mobility aids. To overcome the mobility limitations of people with disabilities, there is an increasing need for the development of lightweight and portable powered wheelchairs that can be easily loaded. This study aimed to perform an early health technology assessment and a formative usability evaluation on a modular (detachable) powered wheelchair. It aimed to gauge device satisfaction among users, pinpoint areas for improvement, and detect any unforeseen errors to inform future development. Engaging 16 participants, including powered wheelchair users, healthcare professionals, and caregivers, the research evaluated the wheelchair's functionality in various scenarios, emphasizing safety, effectiveness, and convenience. Statistical analyses of task performance and satisfaction surveys highlighted that, while powered wheelchair users successfully completed tasks focusing on driving and power control, healthcare professionals and caregivers encountered difficulties with the wheelchair's assembly and disassembly. Despite general positivity, the surveys indicated mixed satisfaction levels regarding safety, validity, and convenience, with specific issues related to frame durability, seat comfort, and control mechanisms. These findings suggest that refining the wheelchair's design and addressing user concerns could significantly enhance satisfaction and mobility services. Future efforts will include a thorough review of an advanced prototype and further satisfaction assessments.

Comparison of Elicitation Approaches in Early Stage HTA Applied on Artificial Thymus for Patients with DiGeorge Syndrome

This paper focuses on research in expert elicitation as a part of the early stage health technology assessment (eHTA). The current state of affairs is analysed and two elicitation approaches are compared-the four fixed intervals method and the histogram method-as applied to an example of early assessment of clinical effectiveness of artificial thymus for patients with DiGeorge syndrome. A survey was carried out consisting of four questions concerning the topic, with the aim to apply the elicitation methods. Eight experts answered the questions using both elicitation methods. Based on their answers, the methods were compared visually and by means of statistical tests. In order to compare the perception of the two elicitation methods, the survey also included questions regarding the experts' subjective preferences. The results of the comparison of the two elicitation approaches did not clearly confirm which method was more beneficial and better; however, it was possible to indicate which of the two methods is better suited for different types of experts. Before selecting an elicitation method as a part of eHTA, it is advisable to effectively consider the technology to be assessed and the type of experts to be invited to share their opinion.

Clarifying the unmet clinical need during medical device innovation in women's health - A narrative review

Medical technologies are pervasive across women's health, spanning across obstetric and gynecological care. FemTech, the sector responsible for developing these technologies, is growing at 15.6% per annum. However, there are concerns of disconnects between new product development (NPD) and the care afforded to women in consequence of implementing these innovations. The most crucial stage of NPD involves understanding the clinical need. Without a clear need and clinical use case, innovators risk developing solutions which do not address the issues women and caregivers experience. Thus, the product will miss the market and experience limited uptake. Tools for performing clinical needs assessments and defining the use case are being developed. This review provides an analysis of their strengths and weaknesses to inform FemTech innovators of the available resources. We further discuss concepts for creating a unified approach to assessing unmet needs such that technologies have a higher chance of improving women's healthcare.

Chest Drainage Therapy: What Comes out of Pandora's Box Can Affect Patient Outcomes

Background: Over the last 100 years, the original three-bottle chest drainage system has been variously engineered into compact disposables and electronic units. Clinicians are now surrounded by a plethora of different types of systems, but little is known about the way that they work and perform. Thus, we sought to test the performance of the most commonly used chest drainage units under conditions that are relevant to clinical practice. Methods: A pleural space environment simulator was built. Thirty-two units were tested under four clinical scenarios: air leak interpretation during quiet breathing and after obstructed inspiration (−5 to −150 cmH2O), a buildup of negative pressure (−100 cmH2O), a bronchopleural fistula (10 L/min) and the need for effective external suction in the presence of air leakage. Twenty-five units were “traditional” thoracic drainages, five were “digital” low-flow/low-vacuum pumps and two were hybrids (a combination of the two). According to the design of the seal and of the suction control, the units were classified as wet-wet, wet-dry and dry-dry. Results: All wet units showed reverse air flow, with the potential to mimic an air leak when there was none. Ten wet units showed no automatic negative pressure relief features, while five dry-dry did but were slow to react. Ten wet and five dry-dry units showed no capability to handle a 10 L/min leak, as they were restrictive to flow (peak pressure up to 55 cmH2O). Only seven dry-suction units were able to maintain the set suction at high airflow rates (>20 L/min). Conclusions: Different chest drainage unit designs lead to different performances, some of which may negatively impact patient outcomes. This sounds the call to tailor our clinical practice for the individual patient. A paradigm shift to better understand all components of pleural physiology post-surgical intervention on this relatively neglected topic is needed to improve our daily practice.

Medtech innovation guide: an empiric model to support medical technology innovation

Innovation has become increasingly important for most industries to cope with rapid technological changes as well as changing societal needs. Even though there are many sectors with specific needs when it comes to supporting innovation, the medical technology sector is facing several unique challenges that both increases the lead-time from idea to finished product and decreases the number of innovations that are developed. This paper presents a proposed innovation guide that has been developed and evaluated as a support for the innovation process within medical technology research. The guide takes the unique characteristics of the medical technology sector into account and serves as a usable guide for the innovator. The complete guide contains both a structure for the process and a usable web application to support the journey from idea to finished products and services. The paper also includes a new readiness level, Sect. 4.2 to provide support both when developing and determining the readiness for clinical implementation of a medical technology innovation.

Methods for Early Assessment of the Societal Value of Health Technologies: A Scoping Review and Proposal for Classification

OBJECTIVES

Early assessments of health technologies help to better align and integrate their development and assessment. Such assessments can take many forms and serve different purposes, hampering users in their selection of the most appropriate method for a specific goal. The aim of this scoping review was to structure the large set of methods according to their specific goal.

METHODS

A scoping review was conducted using PubMed and reference lists of retrieved articles, to identify review studies with a methodological focus. From the included reviews, all individual methods were listed. Based on additional literature and examples, we extracted the specific goal of each method. All goals were clustered to derive a set of subclasses and methods were grouped into these subclasses.

RESULTS

Of the 404 screened, 5 reviews were included, and 1 was added when searching reference lists. The reviews described 56 methods, of which 43 (77%) were included and classified as methods to (1) explore the nature and magnitude of the problem, (2) estimate the nature and magnitude of the expected (societal) value, (3) identify conditions for the potential value to materialize, and (4) help develop and design the type of research that is needed.

CONCLUSIONS

The wide range of methods for exploring the societal value of health technologies at an early stage of development can be subdivided into a limited number of classes, distinguishing methods according to their specific objective. This facilitates selection of appropriate methods, depending on the specific needs and aims.

Technology readiness of medical students and the association of technology readiness with specialty interest

BACKGROUND

Technology readiness (TR) is a construct which characterizes an individual's propensity to utilize new technology. Despite increased technology use in healthcare, limited data exists on medical student TR and the relation of TR with specialty interest. This study assesses the TR of 2nd year medical students and its association with specialty interest.

METHODS

Respondents completed a survey assessing their most preferred specialty, specialty interests, and technology readiness using a 5-point Likert scale. Using Chi-square analysis, we examined the relation between demographics, TR, and specialty interest.

RESULTS

This study obtained a 45.7% (n = 53/116) response rate demonstrating that 79.2% (n = 42/53) of students were "technology ready." Male students were more likely to be technology ready (95.2%, n = 20/21, vs 68.8%, n = 22/32, p = 0.02) when compared to female students. Technology ready students were associated with being more interested in "Technology-Focused" specialties compared to students who were not technology ready (88.5%, n = 23/26 vs 70.4%, n = 19/27, p = 0.104).

CONCLUSIONS

As a cohort, most medical students were technology ready. It is inconclusive if technology ready students are more likely to be interested in technology-focused specialties due to the limited sample size of this study, although with an increased sample size, an improved understanding on technology readiness and its potential impact on student specialty interest may be obtained. Furthermore, knowledge of TR may aid in developing targeted technology-based education programs and in improving remedial approaches for students who are less comfortable with new technology.

Impact of entrepreneurship training on clinician engagement in innovation creation: an evaluation of the Johns Hopkins Hexcite programme

Background

Academic health science centres are an ideal location to translate innovative discoveries into clinical practice. However, increased cost, decreased time and encroaching technology are few of the challenges that academic clinicians face in an increasingly digitised healthcare industry. Academic health science centres have begun creating training to involve clinicians in developing and deploying innovative solutions. Few of these programmes engage clinicians in interactive and interdisciplinary activities.

Approach

Hexcite is a 16-week entrepreneurship training programme at Johns Hopkins. During the programme, clinicians with innovative clinical software ideas learn how to launch start-ups. Clinicians accepted into the programme team up with a business expert, design expert and technical expert. Teams participate in 15 expert-led interactive 3-hour workshops, interview potential customers, regularly pitch their ideas to industry experts and iteratively refine their products.

Methods

This report examined anonymous participant feedback, quantitative data from team productivity reports, and interview responses between 2015 and 2019. Outcomes were assessed using the Kirkpatrick Model.

Results and conclusion

Many clinicians reported improved understanding of team building, design thinking and marketing communications as well as increased involvement in innovation. Many teams received funding after Hexcite. Outcomes from previous cohorts will guide more robust evaluation measures for future cohorts.

[Dementia prevention and primary care: Estimation of the target population]

BACKGROUND

The prevention of dementia, especially the cardiovascular prevention of cognitive disorders, is increasingly coming into the focus of health services research. The aim of this study is to determine the possible target population for dementia prevention approaches as well as frequency of health examinations (HE) in individual general practitioner offices (GP).

METHOD

987 GP practices, which are covered by the nationwide IMS Disease Analyzer database (IQVIA) have been investigated for the prevalence of the following diagnoses, which are considered risk factors for the development of dementia Hypertension, obesity, hearing loss in each age group 45-65 and diabetes and depression in the age group 65 and older. In addition, it was recorded how many of these patients received a HE).

RESULTS

In a sample of 2,398,405 patients receiving primary care, the target population relevant for dementia prevention measures in 2018 consisted of 191,883 patients with hypertension, 23,308 with obesity, 5,059 with hearing loss, 120,200 with diabetes and 43,233 with depression. More than a quarter of these patients have already had a HE. In 2018, patients with hypertension (N=51), diabetes (N=30.5) and depression (N=11.3) were the most frequently treated patients, less frequently patients with obesity (N=8.2) and hearing loss (N=1.6).

CONCLUSION

On the basis of defined diagnoses in certain phases of life, a manageable group of patients can be identified who are eligible for specific dementia preventive interventions. The implementation of dementia preventive interventions in practices will be more difficult for the less frequent treatment diagnoses obesity and hearing loss than for the much more frequent treatment diagnoses hypertension, diabetes and depression.

Overcoming Challenges with the Adoption of Point-of-Care Testing: From Technology Push and Clinical Needs to Value Propositions

Major technical challenges often prevent developers from producing new point-of-care technologies that deliver the required clinical performance in the intended settings of use. But even when devices meet clinical requirements, they can fail to be adopted and successfully implemented. Adoption barriers occur when decision makers do not understand the "value proposition" of new technologies. Current discussions of value in the context of point-of-care testing focus predominantly on the intended use and performance of the device from the manufacturer's point-of-view. However, the perspective of potential adopters in determining whether new devices provide value is also important, as is the opinion of all stakeholders who will be impacted. Incorporating value concepts into decisions made across the full development-to-adoption continuum can increase the likelihood that point-of-care testing will have the desired impact on health care delivery and patient outcomes. This article discusses how various approaches to technology development impact adoption and compares the characteristics of these approaches to emerging value concepts. It also provides an overview of value initiatives and tools that are being developed to support the evaluation of value propositions. These are presented for a range of technology adoption decision contexts, with particular applicability to point-of-care testing. Expanding the focus of research to address gaps in both the creation and evaluation of value propositions is imperative in order for value concepts to positively influence the adoption of point-of-care testing.

A randomised controlled trial to assess the feasibility of utilising virtual reality to facilitate analgesia during external cephalic version

External cephalic version (ECV) is associated with a moderate degree of pain. Virtual reality (VR) is a technology that has shown promise in offering procedural analgesia. We undertook a clinical pilot to assess the viability of VR to reduce pain during ECV. In an open randomised controlled trial (RCT), we randomised 50 women to either VR or standard care each (25 per group). Women receiving VR were administered VR content (Skylights) via a headset. Pre- and post-procedural measures of pain, anxiety, device experience and vital signs were measured. There were no significant differences between groups (VR/no VR) in pain scores (60.68 vs 49.76; p = 0.2), ECV success rates (80% vs 76%; p = 0.7) or anxiety levels. The women receiving VR had a significantly higher anticipation of pain pre-procedurally (70.0 vs 50.0; p = 0.03). 20 (80%) of the VR women indicated that they would use VR again and 22 (88%) indicated they would recommend it to a friend having ECV. There were no significant differences between groups for side effects encountered or changes in vital signs. We have shown that using VR during ECV is feasible and appears safe. Our results inform the design of future RCTs.
