Mapping Factors That Affect the Uptake of Digital Therapeutics Within Health Systems: Scoping Review.

BACKGROUND: Digital therapeutics are patient-facing digital health interventions that can significantly alter the health care landscape. Despite digital therapeutics being used to successfully treat a range of conditions, their uptake in health systems remains limited. Understanding the full spectrum of uptake factors is essential to identify ways in which policy makers and providers can facilitate the adoption of effective digital therapeutics within a health system, as well as the steps developers can take to assist in the deployment of products. OBJECTIVE: In this review, we aimed to map the most frequently discussed factors that determine the integration of digital therapeutics into health systems and practical use of digital therapeutics by patients and professionals. METHODS: A scoping review was conducted in MEDLINE, Web of Science, Cochrane Database of Systematic Reviews, and Google Scholar. Relevant data were extracted and synthesized using a thematic analysis. RESULTS: We identified 35,541 academic and 221 gray literature reports, with 244 (0.69%) included in the review, covering 35 countries. Overall, 85 factors that can impact the uptake of digital therapeutics were extracted and pooled into 5 categories: policy and system, patient characteristics, properties of digital therapeutics, characteristics of health professionals, and outcomes. The need for a regulatory framework for digital therapeutics was the most stated factor at the policy level. Demographic characteristics formed the most iterated patient-related factor, whereas digital literacy was considered the most important factor for health professionals. Among the properties of digital therapeutics, their interoperability across the broader health system was most emphasized. Finally, the ability to expand access to health care was the most frequently stated outcome measure. CONCLUSIONS: The map of factors developed in this review offers a multistakeholder approach to recognizing the uptake factors of digital therapeutics in the health care pathway and provides an analytical tool for policy makers to assess their health system's readiness for digital therapeutics.

Using team-based revision to prepare medical students for the prescribing safety assessment.

BACKGROUND: The Prescribing Safety Assessment (PSA) is an online assessment of safe and effective prescribing, taken by final-year UK medical students. To prepare students for the PSA, we used a modified form of team-based learning, team-based revision (TBR), in which students consolidate previously learned prescribing knowledge and skills across a broad range of topics. We evaluated students' response to TBR and their perceptions of team working. METHODS: Eight TBR sessions based on the PSA blueprint were conducted over two days by three faculty members for final year medical students. During TBR sessions, students worked in small groups answering individual multiple-choice questions, followed by group multiple-choice questions. They subsequently answered open-ended questions in their groups, with answers written on a drug chart to increase authenticity. Students completed surveys using Likert-type items to determine views on TBR and their confidence in prescribing. RESULTS: The majority of respondents agreed that the sessions were useful for preparation both for the PSA (82%) and Foundation Year 1 (78%). 92% agreed that using drug-charts aided learning. Prescribing confidence increased significantly after TBR (median pre-TBR: 2, post-TBR: 5, p<0.0001). TBR significantly improved attitudes towards "team experience" (p<0.001), "team impact on quality of learning" (p<0.01) and "team impact on clinical reasoning ability" (p<0.001). CONCLUSIONS: Team-based revision is a resource-efficient addition to undergraduate prescribing teaching and can help with preparation for the PSA. A short course of TBR was effective in influencing students' attitudes towards teamwork.

Very-short-answer questions: reliability, discrimination and acceptability.

CONTEXT: Single-best-answer questions (SBAQs) have been widely used to test knowledge because they are easy to mark and demonstrate high reliability. However, SBAQs have been criticised for being subject to cueing. OBJECTIVES: We used a novel assessment tool that facilitates efficient marking of open-ended very-short-answer questions (VSAQs). We compared VSAQs with SBAQs with regard to reliability, discrimination and student performance, and evaluated the acceptability of VSAQs. METHODS: Medical students were randomised to sit a 60-question assessment administered in either VSAQ and then SBAQ format (Group 1, n = 155) or the reverse (Group 2, n = 144). The VSAQs were delivered on a tablet; responses were computer-marked and subsequently reviewed by two examiners. The standard error of measurement (SEM) across the ability spectrum was estimated using item response theory. RESULTS: The review of machine-marked questions took an average of 1 minute, 36 seconds per question for all students. The VSAQs had high reliability (alpha: 0.91), a significantly lower SEM than the SBAQs (p < 0.001) and higher mean item-total point biserial correlations (p < 0.001). The VSAQ scores were significantly lower than the SBAQ scores (p < 0.001). The difference in scores between VSAQs and SBAQs was attenuated in Group 2. Although 80.4% of students found the VSAQs more difficult, 69.2% found them more authentic. CONCLUSIONS: The VSAQ format demonstrated high reliability and discrimination and items were perceived as more authentic. The SBAQ format was associated with significant cueing. The present results suggest the VSAQ format has a higher degree of validity.

Delayed Diagnosis of Pharyngeal Perforation following Exploding Tyre Blast Barotrauma.

Introduction. Pharyngoesophageal perforation secondary to barotrauma is a rare phenomenon that can have serious complications if identified late. It is challenging to detect due to nonspecific symptoms. We present a case in which detection proved difficult leading to delayed diagnosis. Case Report. A 27-year-old mechanic presented with haemoptysis, dysphonia, and odynophagia after a car tyre exploded in his face. Flexible nasoendoscopy (FNE) revealed blood in the pharynx, thought to represent mucosal haemorrhage. Initial treatment consisted of IV dexamethasone and antibiotics. After 3 days, odynophagia persisted prompting a CT scan. This revealed a defect in the posterior hypopharynx and surgical emphysema in the deep neck tissues. Contrast swallow confirmed posterior hypopharyngeal leak. NG feeding was commenced until repeated contrast swallow confirmed resolution of the defect. Discussion. Prompt nonsurgical management of pharyngoesophageal perforation has good outcomes but untreated perforation can have serious complications. FNE should be performed routinely, but only a contrast swallow can diagnose a functional perforation. Clinicians should have a high index of clinical suspicion when patients present with barotrauma and odynophagia. Patients should be kept nil by mouth until perforation has been excluded. Conclusion. When faced with cases of facial barotrauma, clinicians should have a low threshold for further imaging to exclude pharyngoesophageal perforation.
