- ItemAdherence to referral criteria at admission and patient management at a specialized burns centre : the case of the red cross War Memorial Children’s Hospital in Cape Town, South Africa(MDPI, 2017-07-06) Boissin, Constance; Hasselberg, Marie; Kronblad, Emil; Kim, So-Mang; Wallis, Lee; Rode, Heinz; Laflamme, LucieENGLISH ABSTRACT: Referral guidelines for burn care are meant to assist in decision-making as regards patient transfer and admissions to specialized units. Little is known, however, concerning how closely they are followed and whether they are linked to patient care. This is the object of the current study, focused on the paediatric burns centre of the Red Cross War Memorial Children’s Hospital in Cape Town, South Africa. All patients admitted to the centre during the winters of 2011–2015 (n = 1165) were included. The patient files were scrutinized to clarify whether the referral criteria in place were identified (seven in total) and to compile data on patient and injury characteristics. A case was defined as adherent to the criteria when at least one criterion was fulfilled and adherence was expressed as a percentage with 95% confidence intervals, for all years aggregated as well as by year and by patient or injury characteristics. The association between adherence to any individual criterion and hospital care (surgery or longer length of stay) was measured using logistic regressions. The overall adherence was 93.4% (100% among children under 2 years of age and 86% among the others) and it did not vary remarkably over time. The two criteria of “injury sustained at a specific anatomical site” (85.2%) and “young age” (51.9%) were those most often identified. Children aged 2 years or older were more likely to undergo surgery or to stay longer than those of young age (although a referral criterion) and so were those with higher injury severity (a referral criterion). In this specialized paediatric burns centre, children are admitted mainly according to the guidelines. However, given the high prevalence of paediatric burns in the region and the limited resources at the burns centre, adherence to the guidelines need to be further studied at all healthcare levels in the province.
- ItemImage-based medical expert teleconsultation in acute care of injuries : a systematic review of effects on information accuracy, diagnostic validity, clinical outcome, and user satisfaction(PLoS, 2014-06) Hasselberg, Marie; Beer, Netta; Blom, Lisa; Wallis, Lee A.; Laflamme, LucieObjective: To systematically review the literature on image-based telemedicine for medical expert consultation in acute care of injuries, considering system, user, and clinical aspects. Design: Systematic review of peer-reviewed journal articles. Data sources: Searches of five databases and in eligible articles, relevant reviews, and specialized peer-reviewed journals. Eligibility criteria: Studies were included that covered teleconsultation systems based on image capture and transfer with the objective of seeking medical expertise for the diagnostic and treatment of acute injury care and that presented the evaluation of one or several aspects of the system based on empirical data. Studies of systems not under routine practice or including real-time interactive video conferencing were excluded. Method: The procedures used in this review followed the PRISMA Statement. Predefined criteria were used for the assessment of the risk of bias. The DeLone and McLean Information System Success Model was used as a framework to synthesise the results according to system quality, user satisfaction, information quality and net benefits. All data extractions were done by at least two reviewers independently. Results: Out of 331 articles, 24 were found eligible. Diagnostic validity and management outcomes were often studied; fewer studies focused on system quality and user satisfaction. Most systems were evaluated at a feasibility stage or during small-scale pilot testing. Although the results of the evaluations were generally positive, biases in the methodology of evaluation were concerning selection, performance and exclusion. Gold standards and statistical tests were not always used when assessing diagnostic validity and patient management. Conclusions: Image-based telemedicine systems for injury emergency care tend to support valid diagnosis and influence patient management. The evidence relates to a few clinical fields, and has substantial methodological shortcomings. As in the case of telemedicine in general, user and system quality aspects are poorly documented, both of which affect scale up of such programs.
- ItemA roadmap for the implementation of mHealth innovations for image-based diagnostic support in clinical and public-health settings : a focus on front-line health workers and health-system organizations(Taylor & Francis Open, 2017) Wallis, Lee; Hasselberg, Marie; Barkman, Catharina; Bogoch, Isaac; Broomhead, Sean; Dumont, Guy; Groenewald, Johann; Lundin, Johan; Bergendahl, Johan Norell; Nyasulu, Peter; Olofsson, Maud; Weinehall, Lars; Laflamme, LucieBackground: Diagnostic support for clinicians is a domain of application of mHealth technologies with a slow uptake despite promising opportunities, such as image-based clinical support. The absence of a roadmap for the adoption and implementation of these types of applications is a further obstacle. Objectives: This article provides the groundwork for a roadmap to implement image-based support for clinicians, focusing on how to overcome potential barriers affecting front-line users, the health-care organization and the technical system. Methods: A consensual approach was used during a two-day roundtable meeting gathering a convenience sample of stakeholders (n = 50) from clinical, research, policymaking and business fields and from different countries. A series of sessions was held including small group discussions followed by reports to the plenary. Session moderators synthesized the reports in a number of theme-specific strategies that were presented to the participants again at the end of the meeting for them to determine their individual priority. Results: There were four to seven strategies derived from the thematic sessions. Once reviewed and prioritized by the participants some received greater priorities than others. As an example, of the seven strategies related to the front-line users, three received greater priority: the need for any system to significantly add value to the users; the usability of mHealth apps; and the goodness-of-fit into the work flow. Further, three aspects cut across the themes: ease of integration of the mHealth applications; solid ICT infrastructure and support network; and interoperability. Conclusions: Research and development in image-based diagnostic pave the way to making health care more accessible and more equitable. The successful implementation of those solutions will necessitate a seamless introduction into routines, adequate technical support and significant added value.
- ItemA smartphone app and cloud-based consultation system for burn injury emergency care(PLoS, 2016-02-16) Wallis, Lee A.; Fleming, Julian; Hasselberg, Marie; Laflamme, Lucie; Lundin, JohanBackground Each year more than 10 million people worldwide are burned severely enough to require medical attention, with clinical outcomes noticeably worse in resource poor settings. Expert clinical advice on acute injuries can play a determinant role and there is a need for novel approaches that allow for timely access to advice. We developed an interactive mobile phone application that enables transfer of both patient data and pictures of a wound from the point-of-care to a remote burns expert who, in turn, provides advice back. Methods and Results The application is an integrated clinical decision support system that includes a mobile phone application and server software running in a cloud environment. The client application is installed on a smartphone and structured patient data and photographs can be captured in a protocol driven manner. The user can indicate the specific injured body surface(s) through a touchscreen interface and an integrated calculator estimates the total body surface area that the burn injury affects. Predefined standardised care advice including total fluid requirement is provided immediately by the software and the case data are relayed to a cloud server. A text message is automatically sent to a burn expert on call who then can access the cloud server with the smartphone app or a web browser, review the case and pictures, and respond with both structured and personalized advice to the health care professional at the point-of-care. Conclusions In this article, we present the design of the smartphone and the server application alongside the type of structured patient data collected together with the pictures taken at point-of-care. We report on how the application will be introduced at point-of-care and how its clinical impact will be evaluated prior to roll out. Challenges, strengths and limitations of the system are identified that may help materialising or hinder the expected outcome to provide a solution for remote consultation on burns that can be integrated into routine acute clinical care and thereby promote equity in injury emergency care, a growing public health burden.
- ItemA smartphone-based consultation system for acute burns – methodological challenges related to follow-up of the system(Taylor & Francis Open, 2017) Hasselberg, Marie; Wallis, Lee; Blessing, Paul; Laflamme, LucieBackground: A smartphone-based consultation system for acute burns is currently being implemented in the Western Cape, South Africa. Even though studies indicate that similar systems for burns tend to support valid diagnosis and influence patient management, the evidence is still sparse. There is a need for more in-depth evaluations, not least in resource-constrained settings where mHealth projects are increasing. Objective: This article describes the consultation system and assessments in relation to its implementation with a special focus on methodological challenges. Methods: A number of evaluations and assessments have been conducted, are ongoing or planned for in relation to the implementation of the teleconsultation system. Initial assessments showed that size and depth of burns could be assessed at least as well using photographs as at bedside and that the image quality of handheld devices can be used as well as computers. Studies on system usability are currently being done with a mixed-methods approach. A historical cohort design will be applied to assess the potential health impact of the system. Patients with burn injuries where the doctor at point of care has used the app to receive diagnostic support from a burns expert will be considered as exposed and patients with burn injuries where the app has not been used will be considered as non-exposed. Conclusions: Smartphone-based consultation systems have the potential to strengthen the assessment of burn injury in many settings. However, ethically and methodologically sound evaluations are needed to find the best systems and solutions. This article identifies challenges and suggests potential assessments in relation to the implementation of such a system.
