Non-acute Settings Research Articles

Utilising co-design to develop a lived experience informed personal safety tool within a mental health community rehabilitation setting.

Mental health personal safety tools aim to promote a recovery focus and empower an individualised approach to consumer care. These clinical tools are predominantly utilised in acute mental health settings with a person during or straight after a crisis. There is currently a gap in the literature regarding the preparation of personal safety tools in non-acute mental health settings. This descriptive article discusses the learnings and outcomes from a co-designed project that aimed to develop a personal safety tool suitable for a community mental health rehabilitation setting. Seven people with lived experience engaging within a mental health community-based rehabilitation service were recruited through convenience sampling to participate in the co-design project. A focus group approach was utilised during four group meetings to develop a personal safety tool template. Experiences and ideas about safety planning were transcribed during meetings and thematic analysis extracted key themes. Five steps underpinned the co-design process that included identifying the need, establishing the co-design group, planning, design and development, and review and closure. Consumer involvement commenced at step two of the co-design process. The completed personal safety tool was designed with consumer input and review. The personal safety tool consisted of nine intervention components. Four key themes emerged from focus group meetings that informed the content of the tool: (i) ensuring the personal safety tool is individualised and meaningful, (ii) promoting exploration of personal strengths and interests, (iii) enabling opportunities to learn self-management skills, and (iv) treating the personal safety tool as a dynamic and adaptable tool. Findings suggest that a personal safety tool targeted to a mental health community-based rehabilitation setting should have an individualised and preventative focus to mental health care. Embedding co-design principles can support opportunities for meaningful consumer engagement and establishing consumer and clinician partnerships.

Technology-Related Safety Events in Primary and Community Care Settings: A Scoping Review.

This scoping review assesses the current knowledge on technology-related safety events in primary and community care settings, focusing on patient safety and harm. Utilizing Arksey and O'Malley's methodological framework, a comprehensive literature search was conducted across various databases, yielding 17 relevant articles. The review highlighted predominant safety event issues, such as technology limitations, incorrect data, and software malfunctions, and identified essential risk mitigation strategies. Consultation with healthcare leaders reinforced these findings and revealed additional organizational challenges, emphasizing the need for continuous monitoring, reporting, and analyzing of HIT-related safety concerns. The findings suggest that while safety events in non-acute settings share similarities with those in acute care, they require specific attention and further research.

Missed Opportunities: A Narrative Review on Why Nonoccupational Postexposure Prophylaxis for HIV Is Underutilized.

Postexposure prophylaxis (PEP) is an important tool for preventing HIV infection but remains underutilized. In this narrative review, we aim to summarize the frequency of missed opportunities for prescribing PEP among studies from around the world, discuss the complexities of the challenges facing PEP provision, and describe possible solutions. We identified 20 studies published in the last 10 years among 43 832 individuals, of whom an estimated 41 477 were eligible for PEP. Of those eligible for PEP, PEP was prescribed among 27 705 (66.8%). There was a significant difference in PEP prescriptions in acute compared with non-acute care settings (63.5% vs 94.5%; P < .001). Emergent themes contributing to PEP underutilization included lack of provider and patient awareness, reduced PEP acceptability, HIV stigma and homophobia, lack of access (either to care or to medication), and stigmatizing policies. Each of those issues should be the focus of future PEP implementation efforts.

Prescription and Dispensation of QT-Prolonging Medications in Individuals Receiving Hemodialysis

Individuals with dialysis-dependent kidney failure have numerous risk factors for medication-related adverse events, including receipt of care by multiple clinicians and initiation of some QT-prolonging medications with known risk of torsades de pointes (TdP), which is associated with higher risk of sudden cardiac death. Little is known about the prescription and dispensation patterns of QT-prolonging medications among people receiving dialysis, hindering efforts to reduce drug-related harm from these and other medications in this high-risk population. To examine prescription and dispensation patterns of QT-prolonging medications with known TdP risk and selected interacting medications prescribed to individuals receiving hemodialysis. This cross-sectional study included patients 60 years or older who were enrolled in Medicare Parts A, B, and D receiving in-center hemodialysis from January 1 to December 31, 2019. Analyses were conducted from October 20, 2022, to June 16, 2023. New-user prescriptions for the 7 most frequently filled QT-prolonging medications characterized by the timing of the new prescription relative to acute care encounters, the type of prescribing clinician and pharmacy that dispensed the medication, and concomitant use of selected medications known to interact with the 7 most frequently filled QT-prolonging medications with known TdP risk. The main outcomes were the frequencies of the most commonly filled and new-use episodes of QT-prolonging medications; the timing of medication fills relative to acute care events; prescribers and dispensing pharmacy characteristics for new use of medications; and the frequency and types of new-use episodes with concurrent use of potentially interacting medications. Of 20 761 individuals receiving hemodialysis in 2019 (mean [SD] age, 74 [7] years; 51.1% male), 10 992 (52.9%) filled a study drug prescription. Approximately 80% (from 78.6% for odansetron to 93.9% for escitalopram) of study drug new-use prescriptions occurred outside of an acute care event. Between 36.8% and 61.0% of individual prescriptions originated from general medicine clinicians. Between 16.4% and 26.2% of these prescriptions occurred with the use of another QT-prolonging medication. Most potentially interacting drugs were prescribed by different clinicians (46.3%-65.5%). In this cross-sectional study, QT-prolonging medications for individuals with dialysis-dependent kidney failure were commonly prescribed by nonnephrology clinicians and from nonacute settings. Prescriptions for potentially interacting medications often originated from different prescribers. Strategies aimed at minimizing high-risk medication-prescribing practices in the population undergoing dialysis are needed.

SARS-CoV-2 immunity and reasons for non-vaccination among healthcare workers from eastern and northern Switzerland: results from a nested multicentre cross-sectional study.

We aimed to assess the extent of SARS-CoV-2 humoral immunity elicited by previous infections and/or vaccination among healthcare workers, and to identify reasons why healthcare workers decided against vaccination. This nested cross-sectional study included volunteer healthcare workers from 14 healthcare institutions in German-speaking Switzerland. In January 2021, SARS-CoV-2 vaccines were available for healthcare workers. In May and June 2022, participants answered electronic questionnaires regarding baseline characteristics including SARS-CoV-2 vaccination status (with one or more vaccine doses defined as vaccinated) and previous SARS-CoV-2 infections. Unvaccinated participants indicated their reasons for non-vaccination. Participants underwent testing for SARS-CoV-2 anti-spike (anti-S) and anti-nucleocapsid (anti-N) antibodies. Antibody prevalence was described across age groups. In addition, we performed multivariable logistic regression to identify baseline characteristics independently associated with non-vaccination and described reasons for non-vaccination. Among 22,438 eligible employees, 3,436 (15%) participated; the median age was 43.7 years (range 16-73), 2,794 (81.3%) were female, and 1,407 (47.7%) identified as nurses; 3,414 (99.4%) underwent serology testing, among whom 3,383 (99.0%) had detectable anti-S (3,357, 98.3%) antibodies, anti-N (2,396, 70.1%) antibodies, or both (2,370, 69.4%). A total of 296 (8.6%) healthcare workers were unvaccinated, whereas 3,140 (91.4%) were vaccinated. In multivariable analysis, age (adjusted OR [aOR] 1.02 per year, 95% CI 1.01-1.03), being a physician (aOR 3.22, 95% CI 1.75-5.92) or administrator (aOR 1.88, 95% CI 1.27-2.80), and having higher education (aOR 2.23, 95% CI 1.09-4.57) were positively associated with vaccine uptake, whereas working in non-acute care (aOR 0.58, 95% CI 0.34-0.97), active smoking (aOR 0.68, 95% CI 0.51-0.91), and taking prophylactic home remedies against SARS-CoV-2 (aOR 0.42, 95% CI 0.31-0.56) were negatively associated. Important reasons for non-vaccination were a belief that the vaccine might not have long-lasting immunity (267/291, 92.1%) and a preference for gaining naturally acquired instead of vaccine-induced immunity (241/289, 83.4%). Almost all healthcare workers in our cohort had specific antibodies against SARS-CoV-2 from natural infection and/or from vaccination. Young healthcare workers and those working in non-acute settings were less likely to be vaccinated, whereas physicians and administrative staff showed higher vaccination uptake. Presumed ineffectiveness of the vaccine is an important reason for non-vaccination.

A cross-sectional study of the psychosocial and occupational impact of COVID-19 among NHS staff: findings from a Northwest London cohort during the second wave

Background: Evidence of the deleterious mental health impact of COVID-19 on healthcare workers shows the priority need to support their psychological wellbeing. We assessed the nature, prevalence and factors associated with the psychosocial and occupational impact of COVID-19 among NHS staff during the pandemic. Methods: A cross-sectional online survey was sent to all NHS provider organisations in Northwest London in January 2021. Results: Of 1,065 participants completing the survey, 906 (85%) provided responses to the full survey. Over half (54.1%; n=543) exceeded the cut-off score for probable mental disorders, 31.1% (n=222) for probable burnout, and similarly for PTSD (28.5%; n=210). 28.6% (n=214) had experienced suicidal thoughts. 58% (n=429) scored &gt;5 out of 10 for emotional and physical exhaustion. Over 30% (n=328) of respondents reported using some kind of staff support service. Staff in pay bands 4-6 were more likely to have common mental disorders (CMD) (OR 2.42 [1.20,4.88]) and PTSD symptoms (OR 4.18 [1.44,12.14]) than lower banded staff. Staff working in acute care settings were more likely to experience CMD (OR 1.50 [1.08,2.07]) and PTSD (OR 1.57 [1.03,2.41]) than in non-acute settings. Low social connectedness and perceived delivery of poor-quality care were highly associated with risk of all mental health problems, apart from alcohol misuse (OR range 1.56-18.34). Conclusions: Psychosocial morbidity and adverse occupational impacts on NHS staff in the second wave of the COVID-19 pandemic echoed that reported in the first wave. Social connection and perception of delivering good care were important, potentially modifiable, mitigating factors.

A core outcome set for evaluating the effectiveness of mixed-diagnosis falls prevention interventions for people with Multiple Sclerosis, Parkinson’s Disease and stroke

Introduction Clinical trials evaluating the effectiveness of falls prevention interventions for people with Multiple Sclerosis (MS), Parkinson’s Disease (PD) and stroke measure heterogeneous outcomes, often omitting those meaningful to patients. A core outcome set (COS) is a standardised set of outcomes that should be assessed in all trials within a research area. The aim of this study was to develop a COS for evaluating mixed-diagnosis falls prevention interventions for people with MS, PD and stroke in non-acute and community settings, with input from relevant stakeholder groups. Methods Previously published research undertaken by the team, including a qualitative study with 20 patients and a review of the literature, were used to derive a longlist of potential outcomes. Outcomes were prioritised for inclusion in the COS using a three-round online Delphi survey. A multi-stakeholder, consensus meeting was conducted to agree upon the final COS and to provide a recommendation for a single outcome measure for each outcome in the COS. Results Forty-eight participants were recruited across four stakeholder groups (researchers, patients, clinicians, and service-planners/policymakers). A total of 42 participants (87.5%) completed all three rounds of the surveys. Sixty-two outcomes were considered for inclusion in the COS throughout the Delphi process. A total of 15 participants attended the consensus meeting where they agreed upon the final COS and accompanying measurement instruments: fall incidence, injurious fall incidence, quality of life, falls self-efficacy, fear of falling, activity curtailment due to fear of falling, and cost-effectiveness. Attendees at the consensus meeting recommended that the proposed mechanism of impact of an intervention is considered when selecting additional outcomes outside of those in the COS to assess. Conclusions This study identified a COS for evaluating the effectiveness of mixed-diagnosis falls prevention interventions for people with MS, PD and stroke. It is recommended that this COS and accompanying measurement instruments be used in all future trials in this research area so that findings can be combined and compared.

Underreported and underrecognized: a comprehensive imaging review of breast injury.

Breast injury is commonly encountered yet it remains significantly underreported. Injury to the breast may arise from either primary mechanisms or secondary or iatrogenic mechanisms. Primary mechanisms of breast injury include blunt force, seat-belt, penetrating, and thermal injury. Secondary or iatrogenic mechanisms of breast injury include breast biopsy or interventionas well as operative intervention and cardiopulmonary resuscitation. The severity of breast injury arising from these mechanisms is broad, ranging from breast contusion to avulsion. Sequelae of breast injury include fat necrosis and Mondor's disease. Radiologists play an integral role in the evaluation and management of breast injury both in the acute and non-acute settings. In the acute setting, radiologists must be able to recognize breast injury arising from primary mechanisms or iatrogenic or secondary mechanisms and to identifyrare but potentially life-threatening complications promptly to ensure timely, appropriate management. In the non-acute setting, radiologists must be able to discern the sequalae of breast injury from other processes to prevent potentially unnecessary further evaluation and intervention. Nonetheless, though breast injury is commonly encountered there remain few guidelines and a lack of established recommendations for the evaluation and management of breast injury. We provide a comprehensive multi-modality imagingreview of breast injury arising in the acute setting as well as the sequela of breast injury arising in the non-acute setting. Moreover, we provide an overview of the management of breast injury.

Learning health systems in rehabilitation care - findings and recommendations from a scoping review

Abstract To meet the challenges posed by an aging population and changing health needs, healthcare systems require transformative action at a systemic level. One solution is to create “learning” health systems (LHS) that generate and apply evidence, innovation and quality to improve the provision of care. Given the lack of research focusing on operationalizing LHSs and the predominance of acute care studies, this scoping review aimed to fill this gap by exploring how LHS frameworks have been conceptualized and operationalized in rehabilitation organizations. The review was conducted according to the JBI guidelines and Arksey &amp; O’Malley methodological framework. Comprehensive search was performed across 5 databases to capture the extent of the literature on this topic specific to rehabilitation. Following screening and data extraction, qualitative content analysis and thematic mapping was employed to explore the selected studies (n = 26). Results were reported in accordance with PRISMA guidelines. Studies conceptualised LHS as organizational infrastructure that supports continuous learning by integrating clinical care and research. It aims generate new knowledge by capturing data from every clinical encounter and applying it to practice through iterative learning cycles, characterized by three phases: Data to Knowledge, Knowledge to Performance, and Performance to Data. Four themes emerged regarding the operationalization of LHS in rehabilitation: creating a functioning data infrastructure; facilitating research; promoting an organizational culture of learning; and person-centredness. This study is the first scoping review on LHSs in the context of rehabilitation, employing a systematic and rigorous process to capture the relevant literature. The review identified key transformational steps to become a LHS e.g., generation, dissemination and implementation of new institutional knowledge and early stakeholder engagement. Findings can be applied across non-acute health settings. Key messages • This is the first scoping review on LHSs in the context of rehabilitation. • The findings will aid organisations in non-acute health settings with the transformational process of becoming LHSs.

Learning healthcare systems and rehabilitation: a scoping review protocol

Background: Healthcare literature has proposed that “learning organisations” (LO) or “learning healthcare systems” (LHS) that continuously generate and apply evidence, innovation, quality, and value can provide better care. This is of value to non-acute healthcare settings such as rehabilitation, which are complex, multi-dimensional and multi-disciplinary in nature. Little is known about how these frameworks have been applied to rehabilitation settings. Objective and inclusion criteria: The aim of this scoping review is to systematically summarise the literature conceptualising and operationalising LHS and LO in rehabilitation settings. Studies will be included which define a LO or LHS, describe an operating LHS/LO or include the translation of research evidence generated from LHS/LO data into healthcare improvement within a rehabilitation context. All study designs will be included. Methods: The guidelines from the Joanna Briggs institute methodology for scoping reviews will be used for this review. The literature search will be performed using a three-step search strategy: an initial limited search of two databases has been performed to identify relevant key words and index terms. The developed search string will be adapted and applied across the following databases: OVID MEDLINE, EMBASE, CINAHL Plus, APA PsycINFO and COCHRANE Database of Systematic Reviews. Reference lists of selected sources and relevant data-hubs will also be searched. A draft data extraction framework will be used and updated iteratively to extract data. Data will be extracted and described to address the research question of how LHS and LO have been conceptualised and operationalised in the context of rehabilitation. Discussion and Implications: There is potential for rehabilitation focused LHSs to advance global rehabilitation services and facilitate best practice. Little is known about how rehabilitation focused LHSs have been constructed and sustained. This will be the first review to explore LHS application in rehabilitation, guiding future development and research.

The effects of aging and frailty on inpatient glycemic control by continuous glucose monitoring in patients with type 2 diabetes

BackgroundOlder adults with diabetes in the hospital are generally managed similarly to younger adults, however, it is unknown if the degree of frailty can affect glucose control among hospitalized patients. MethodsWe examined glycemic parameters derived from continuous glucose monitoring (CGM) in older adults with type 2 diabetes and frailty who were hospitalized in non-acute settings. Data was pooled from 3 prospective studies using CGM including 97 patients wearing Libre CGM sensors and 166 patients wearing Dexcom G6 CGM. Glycemic parameters (time in range (TIR) 70–180; time below range (TBR) <70 and 54 mg/dl) by CGM were compared between 103 older adults ≥60 years and 168 younger adults <60 years. Frailty was assessed using validated laboratory and vital signs frailty index FI-LAB (n = 85), and its effect on hypoglycemia risk was studied. ResultsOlder adults, as compared to younger adults, had significantly lower admission HbA1c (8.76% ± 1.82 vs. 10.25% ± 2.29, p < 0.001), blood glucose (203.89 ± 88.65 vs. 247.86 ± 124.17 mg/dl, p = 0.003), mean daily BG (173.9 ± 41.3 vs. 183.6 ± 45.0 mg/dl, p = 0.07) and higher percent TIR 70–180 mg/dl (59.0 ± 25.6% vs. 51.0 ± 26.1%, p = 0.02) during hospital stay. There was no difference in hypoglycemia occurrence between older and younger adults. Higher FI-LAB score was associated with higher % CGM < 70 mg/dl (0.204) and % CGM < 54 mg/dl (0.217). ConclusionOlder adults with type 2 diabetes have better glycemic control prior to admission and during hospital stay compared to younger adults. Frailty is associated with longer presence of hypoglycemia in non-acute hospital settings.

Multi-organ impairment and long COVID: a 1-year prospective, longitudinal cohort study.

To determine the prevalence of organ impairment in long COVID patients at 6 and 12 months after initial symptoms and to explore links to clinical presentation. Prospective cohort study. Individuals. In individuals recovered from acute COVID-19, we assessed symptoms, health status, and multi-organ tissue characterisation and function. Two non-acute healthcare settings (Oxford and London). Physiological and biochemical investigations were performed at baseline on all individuals, and those with organ impairment were reassessed. Primary outcome was prevalence of single- and multi-organ impairment at 6 and 12 months post COVID-19. A total of 536 individuals (mean age 45 years, 73% female, 89% white, 32% healthcare workers, 13% acute COVID-19 hospitalisation) completed baseline assessment (median: 6 months post COVID-19); 331 (62%) with organ impairment or incidental findings had follow-up, with reduced symptom burden from baseline (median number of symptoms 10 and 3, at 6 and 12 months, respectively). Extreme breathlessness (38% and 30%), cognitive dysfunction (48% and 38%) and poor health-related quality of life (EQ-5D-5L < 0.7; 57% and 45%) were common at 6 and 12 months, and associated with female gender, younger age and single-organ impairment. Single- and multi-organ impairment were present in 69% and 23% at baseline, persisting in 59% and 27% at follow-up, respectively. Organ impairment persisted in 59% of 331 individuals followed up at 1 year post COVID-19, with implications for symptoms, quality of life and longer-term health, signalling the need for prevention and integrated care of long COVID.Trial Registration: ClinicalTrials.gov Identifier: NCT04369807.

Guardians and research staff experiences and views about the consent process in hospital-based paediatric research studies in urban Malawi: A qualitative study

BackgroundObtaining consent has become a standard way of respecting the patient’s rights and autonomy in clinical research. Ethical guidelines recommend that the child’s parent/s or authorised legal guardian provides informed consent for their child’s participation. However, obtaining informed consent in paediatric research is challenging. Parents become vulnerable because of stress related to their child’s illness. Understanding the views held by guardians and researchers about the consent process in Malawi, where there are limitations in health care access and research literacy will assist in developing appropriate consent guidelines.MethodsWe conducted 20 in-depth interviews with guardians of children and research staff who had participated in paediatric clinical trial and observational studies in acute and non-acute settings in the Southern Region of Malawi. Interviews were audio-recorded, transcribed verbatim, and thematically analysed. Interviews were compared across studies and settings to identify differences and similarities in participants’ views about informed consent processes. Data analysis was facilitated by NVIVO 11 software.ResultsAll participants across study types and settings reported that they associated participating in research with therapeutic benefits. Substantial differences were noted in the decision-making process across study settings. Guardians from acute studies felt that the role of their spouses was neglected during consenting, while staff reported that they had problems obtaining consent from guardians when their partners were not present. Across all study types and settings, research staff reported that they emphasised the benefits more than the risks of the study to participants, due to pressure to recruit. Participants from non-acute settings were more likely to recall information shared during the consent process than participants in the acute setting.ConclusionThe health care context, culture and research process influenced participants’ understanding of study information across study types and settings. We advise research managers or principal investigators to define minimum requirements that would not compromise the consent process and conduct study specific training for staff. The use of one size fits all consent process may not be ideal. More guidance is needed on how these differences can be incorporated during the consent process to improve understanding and delivery of consent.Trial registration Not applicable.

Obstacles and Pathways on the Journey to Access Home and Community Care by Older Adults Living With HIV/AIDS in British Columbia, Canada: Thrive, a Community-Based Research Study

Older adults living with HIV (OALHIV) (i.e., age ≥50) now constitute over 50% of all people accessing HIV treatment in British Columbia (BC), Canada. As OALHIV age, the need for supportive care in non-acute settings, including home and community care (HCC), is increasing. The Thrive research project was co-created alongside OALHIV in BC to support people to thrive with a good quality of life (as contrasted with just surviving). Phase 1 of the project linked treatment and demographic records for 5603 OALHIV accessing care in BC. Phase 2 took a community-based research approach with semi-structured interviews to understand obstacles and pathways experienced by 27 OALHIV in accessing HCC. This article summarizes previously published Phase 1 findings and explores Phase 2 findings in-depth. On the HCC journey traveled by OALHIV in BC, there are four main junctures at which obstacles and pathways appear: (1) before referral, (2) during the referral process, (3) at the assessment, and (4) while receiving services. Obstacles are largely related to fluctuating HCC priorities and funding cuts tied to election cycles, requiring systemic and policy changes to enable positive outcomes and impacts in the provision of HCC services. These obstacles can be transformed into pathways through public policy and client-centered, culturally safe care.

Malignant Hyperthermia: Clinical Management

Malignant hyperthermia is a subclinical myopathy in which general anesthesia triggers an uncontrollable contraction of skeletal muscle that leads to a life-threatening hypercatabolic state and an increase in body temperature. The disease is primarily autosomal dominant; mutations in receptors (especially ryanodine receptor type 1) predispose to volatile anesthetic agents or succinylcholine causing an accumulation of intracellular calcium in skeletal muscle that leads to its overactivation and hypermetabolism. In the acute setting, diagnosis is based mainly on clinical presentation and end-tidal capnography, which reveals an increase in end-tidal CO2. Initial treatment measures include discontinuation of the agent causing the reaction and administration of dantrolene. In non-acute settings, there are specific diagnostic tools such as the caffeine-halothane contracture test to confirm suspected cases. MH is a lethal disease and has a high mortality rate if not treated early.

Conceptualising learning healthcare systems and organisations in the context of rehabilitation: a scoping review protocol

Background: Transformative system wide action is needed for healthcare systems to meet the needs of an increasing aging population and changing health needs. One idea is that health systems can become “learning organisations” (LO) or “learning healthcare systems” (LHS) that continuously generate and apply evidence, innovation, quality, and value to provide better care. This is of value to non-acute healthcare settings such as rehabilitation, which are complex, multi-dimensional and multi-disciplinary in nature.

Studies will be included which define a LO or LHS; or describe an operating LHS/LO; or include the translation of research evidence generated from LHS/LO data into healthcare improvement within a rehabilitation context will be included. Study designs such as quantitative, qualitative, mixed method studies, and case studies will be included. Methods: The guidelines from the Joanna Briggs institute methodology for scoping reviews will be used for this review. The literature search will be performed using a three-step search strategy: an initial limited search of two databases has been performed to identify relevant key words and index terms. The developed search string will be adapted and applied across the following databases: OVID MEDLINE, EMBASE, CINAHL Plus, APA PsycINFO and COCHRANE Database of Systematic Reviews. This will be followed by search of the reference lists of selected sources and relevant data-hubs. A draft data extraction framework will be used and updated iteratively to extract data. Frequency counts and qualitative content analysis will be employed to address the research question of how LHS and LO have been conceptualised and operationalised in the context of rehabilitation.

Validation study of machine-learning chest radiograph software in primary and emergency medicine

To evaluate the performance of a machine learning based algorithm tool for chest radiographs (CXRs), applied to a consecutive cohort of historical clinical cases, in comparison to expert chest radiologists. The study comprised 1,960 consecutive CXR from primary care referrals and the emergency department (992 and 968 cases respectively), obtained in 2015 at a UK hospital. Two chest radiologists, each with >20 years of experience independently read all studies in consensus to serve as a reference standard. A chest artificial intelligence (AI) algorithm, Lunit INSIGHT CXR, was run on the CXRs, and results were correlated with those by the expert readers. The area under the receiver operating characteristic curve (AUROC) was calculated for the normal and 10 common findings: atelectasis, fibrosis, calcification, consolidation, lung nodules, cardiomegaly, mediastinal widening, pleural effusion, pneumothorax, and pneumoperitoneum. The ground truth annotation identified 398 primary care and 578 emergency department datasets containing pathologies. The AI algorithm showed AUROC of 0.881-0.999 in the emergency department dataset and 0.881-0.998 in the primary care dataset. The AUROC for each of the findings between the primary care and emergency department datasets did not differ, except for pleural effusion (0.954 versus 0.988, p<0.001). The AI algorithm can accurately and consistently differentiate normal from major thoracic abnormalities in both acute and non-acute settings, and can serve as a triage tool.

Technologies for Fever Screening in the Time of COVID-19: A Review

During the COVID-19 pandemic, there has been an increasing rollout of non-contact fever screening solutions to assist in curbing the spread of disease. This study begins by describing how screening for disease has historically been performed. It proposes four measurement characteristics of an ideal screening solution: non-contact, effective, rapid and low-cost measurements. Next, it reviews the existing literature on fever-screening using non-contact infrared thermometer (NCIT) devices as well as infrared thermography (IRT) devices, as these are two technologies which have experienced increasing use. For this review, 185 research papers were identified, 21 research studies were included after inclusion and exclusion criteria were applied. A total of 35 experiments were identified for analysis and their results tabulated. Of these studies, 66% are IRT and 34% are NCIT, with a median sample size of 430 subjects. 26 experiments involve febrile participants, with a median febrile percentage of 11.22 % of population. The reported sensitivity of febrile detection using NCIT varies from 3.7% to 97% and when using IRT it varies from 15% to 100%. Both indoor and outdoor studies are investigated, as well as those conducted in acute and non-acute settings. The results of this review show a clear lack of consensus on the effectiveness of these systems. Overall, these results indicate that sensitivity and specificity are reduced when using IRT and NCIT technologies compared to other thermometers used in medical practice. Their use should be carefully assessed based on the risks present in each particular measurement scenario.

Transfusion support for patients with sickle cell disease

Red blood cell (RBC) transfusion is an essential treatment for many patients with sickle cell disease (SCD), whose RBCs express hemoglobin S (HbS), a mutated form of hemoglobin A (HbA). Transfusion goals include increasing blood oxygen carrying capacity and decreasing the relative amount of HbS to HbA to mitigate vaso-occlusion in small blood vessels. In situations where correction of severe anemia and reduction in HbS may be achieved without removal of RBCs, simple transfusion may be utilized. Partial manual RBC exchange, which removes blood containing HbS by phlebotomy and replaces with donor blood transfusion sequentially allows for larger changes in the ratio of HbS to HbA when compared to simple transfusion. Automated RBC exchange by apheresis is useful in situations where a rapid and drastic HbS reduction is indicated. Vascular access is an important consideration for transfusion. Although peripheral access may be sufficient, central venous catheters and implantable venous access devices may be necessary for adequate access over time. Blood bank considerations include adequate RBC antigen matching to mitigate the risk of RBC alloimmunization, of which patients with SCD are at risk of developing. Transfusion may be utilized in efforts to intervene in the evolution of potentially life-threatening complications of SCD such as acute stroke, severe acute anemia and acute chest syndrome. Transfusion is also useful in several non-acute settings, such as stroke prevention, pregnancy, pre-surgery, and transfusion support for curative therapies. Individualized treatment plans are an essential component of patient care. Continuous evaluation of clinical indications and evolution of guidelines will continue to optimize care for patients with SCD.
