RESUMO

BACKGROUND: Stroke among younger age groups is increasing globally. While there is a focus on research conducted on people under 65 years who have had a stroke, there is a paucity of data on the incidence and risk factors of stroke among younger people (≤ 30 years). This scoping review examines evidence on incidence and risk factors for perinatal, paediatric and young adult stroke globally. METHODS: The review was guided by the Joanna Briggs Institute's scoping review methodology. A systematic search was conducted on 23rd March 2022 across Medline Ovid, Embase, PsycINFO and Cumulative Index to Nursing and Allied Health Literature (CINAHL). The eligibility criteria included all study designs providing information on the incidence and risk factors of stroke among young people (≤ 30 years) in the last ten years. RESULTS: A total of 5750 articles were identified. After screening, 471 articles (224 cohort studies (47.6%), 164 case studies/case series (34.8%), 35 reviews (7.4%), 30 case-control (6.4%) and 18 combinations of designs (3.8%) were included. There was data from 50 different countries, 199 studies were from high-income countries, upper and middle income (n = 38), lower middle-income (n = 39), low-income (n = 3) countries, international study (n = 7) and a further 185 articles did not state the country of research. Most of the studies (63%) focused on risk factors while incidence constituted 37%. Incidence data were reported heterogeneously across studies, leading to an inability to synthesise data. The three most frequently reported risk factors for perinatal stroke were infections, cardiac conditions, and intrapartum factors. Vasculopathies, infection and cardiac conditions accounted for most reported risk factors for paediatric stroke, while chronic conditions such as diabetes mellitus, vasculopathies and cardiac conditions accounted for the most reported risk factors among young adults. CONCLUSION: This review has highlighted different stroke risk factors for each age cohort of people under 30 years. The low number of epidemiological studies suggests that further research of this type is needed to fully understand the incidence and risk factors in young stroke. A standardised reporting of age groupings of incidence data is imperative to enable the comparison of data from different geographical locations.

RESUMO

PURPOSE: Physical exercise is shown to mitigate catecholamine metabolites; however, it is unknown if exercise-induced increases in sympatho-adrenal activity or catecholamine metabolites are influenced by ingestion of specific catechins found within green tea. This study explored the impact of epigallocatechin gallate (EGCG) ingestion on catecholamine metabolism during graded cycle exercise in humans. METHODS: Eight males (22.4 ± 3.3 years, BMI:25.7 ± 2.4 kg.m2) performed a randomised, placebo-controlled, single-blind, cross-over trial after consumption (1450 mg) of either EGCG or placebo (PLAC) and performed graded cycling to volitional exhaustion. Venous bloods were taken at rest, 2 h post-ingestion and after every 3-min stage. Blood variables were analysed for catecholamines, catecholamine metanephrines and metabolic variables at rest, 2 h post-ingestion (POST-ING), peak rate of lipid oxidation (FATpeak), lactate threshold (LT) and peak rate of oxygen consumption (VO2peak). Data were analysed using SPSS (Version 26). RESULTS: Resting catecholamine and metanephrines were similar between trials. Plasma adrenaline (AD) was lower in ECGC treatment group between trials at FATpeak (P < 0.05), LT (P < 0.001) and VO2peak (P < 0.01). Noradrenaline (NA) was lower under EGCG at POST (P < 0.05), FATpeak (P < 0.05), LT (P < 0.01) and VO2peak (P < 0.05) compared to PLAC. Metanephrines, glucose and lactate increased similarly with exercise intensity in both trials. Lipid oxidation rate was 32% lower in EGCG at FATpeak (EGCG 0.33 ± 0.14 vs. PLAC 0.49 ± 0.11 g.min-1, P < 0.05). Cycle time to exhaustion was similar (NS). CONCLUSION: Acute EGCG supplementation reduced circulating catecholamines but not; metanephrine, glucose or lactates, response to graded exercise. Lower circulating catecholamines may explain a lower lipid oxidation rate.

RESUMO

BACKGROUND: Socioeconomic status (SES) is associated with stroke occurrence and survival following stroke but its association with health-related quality of life (HRQoL) following stroke remains uncertain. We performed a systematic review and meta-analysis to examine the association between SES and HRQoL after stroke. METHODS: PubMed, SCOPUS, EMBASE, and Web of Science were searched to identify relevant cohort and case-control studies between January 2000 and May 2022. Two authors screened titles, abstracts and full text articles. One author extracted data from all included studies. Meta-analyses were performed for studies with comparable measurements of SES and HRQoL. Random effects models were used to estimate pooled summary standardised mean differences in HRQoL by SES. RESULTS: Out of 1,876 citations, 39 studies incorporated measurement of overall HRQoL following stroke and were included in the systematic review, with 17 studies included in the meta-analyses. Overall, reports including education, income, occupation and work status effects on HRQoL after stroke were inconsistent among all included 39 studies. In the global meta-analysis of 17 studies, HRQoL among survivors of stroke was lower in the low SES group than in the high SES group (standardised mean difference (SMD) -0.36, 95% CI -0.52, -0.20, p < 0.0001). When using education and income indicators separately, summary effects were similar to those of the global analysis (low versus high education SMD -0.38, 95% CI -0.57, -0.18, p < 0.0001; low versus high income SMD -0.39, 95% CI -0.59, -0.19, p < 0.0001). CONCLUSIONS: Across all SES indicators, people with stroke who have lower SES have poorer overall HRQoL than those with higher SES. Accessibility and affordability of poststroke support services should be taken into consideration when planning and delivering services to people with low SES.

RESUMO

AIM: Explore the prevalence of childhood anaphylaxis and clinical presentation of anaphylaxis in children across two regional emergency departments over a 7-year period. METHODS: Retrospective audit of all children (0-18 years) presenting to emergency from 1 January 2010 to 31 December 2016 with anaphylaxis, defined by Australasian Society of Clinical Immunology and Allergy definitions and doctor diagnosis. RESULTS: Seven hundred and twenty-four patients were identified with allergic diagnosis, 60% were diagnosed with non-anaphylaxis allergic reactions or unspecified urticaria and 40% with anaphylaxis (n = 286). Annual prevalence of anaphylaxis remained stable over the study period (M = 30.9/10 000 cases, range: 20.8-48.3/10 000). Gender distribution was equal, median age was 9.48 years (interquartile range = 4-15). Most (71%) arrived by private transport. 23% had a prior history of anaphylaxis. Food triggers (44%) were the most common cause of anaphylaxis. Insect bites/stings triggers occurred in 21%. Patients were promptly assessed (average wait time = 13 min), 16% received prior adrenaline injections. Adrenaline was administered in 26% and 20% were admitted to hospital. On discharge, 29% had a follow-up plan, 9% received an allergy clinic referral, 6% anaphylaxis action plan, 26% adrenaline autoinjector prescriptions and allergy testing performed in 6%. CONCLUSIONS: We found a relatively low prevalence of overall childhood anaphylaxis in a regional area. The two most common causes of anaphylaxis in this population (food and bites/stings) recorded increased prevalence providing an opportunity for further study. Significant gaps in evidence-based care of anaphylaxis were noted, demonstrating the need for improved recognition and treatment guideline implementation in regional areas.

RESUMO

Vertical integration (VI) is considered a strategic management plan whereby an organisation has ownership of its supply chain. It is utilised as a method for managing the economic needs and approaches of an organisation and ensuring that a product is readily available for use. From a healthcare perspective, this pertains to the coordination of services or levels of care and allows for adaptation to changing circumstances. This study reviews existing literature on VI in a healthcare setting to assess feasibility and effectiveness of this proposed solution. A theoretical literature review was performed utilising conceptual categorisation to understand how VI may benefit community care organisations, using the needs of a local organisation as an example. Seventeen articles were included from a range of databases and grey literature with findings categorised according to two research questions. The findings suggest that for VI to be effective and efficient it is important to consider the following themes: market failure, barriers to entry, productive capabilities and specific healthcare issues. In conclusion, from a management and economic perspective, when markets are not functioning efficiently and are in disequilibrium, VI may provide an appropriate avenue to address these problems, in particular for community care organisations.

RESUMO

OBJECTIVE: To understand the experiences of vulnerable clients who used telehealth during the Coronavirus pandemic. DESIGN: The study employed a qualitative enquiry, utilising semi-structured interviews lasting 30-60 minutes with a thematic analysis approach to explore factors influencing client experience with telehealth. SETTING: A wide range of locations across Tasmania, Australia. PARTICIPANTS: Twelve participants who were considered to be vulnerable on a number of domains, including: health and human wellbeing factors, social risk factors, functional limitations, and individual behavioural factors. INTERVENTIONS: The provision of telehealth consultations to vulnerable clients. MAIN OUTCOME MEASURES: Four global themes were discovered: i) Telehealth saves time, money and energy; ii) User friendly technology facilitates care; iii) Rapport and confidentiality helps clients to feel safe; and iv) Fit for purpose telehealth provides a quality service. RESULTS: The discovered themes entailed the major finding that most participants were satisfied with the overall quality of the telehealth service they received and the convenience of this service. Concerns were raised regarding the limitations around social interaction, physical examination, and access to fit-for-purpose telehealth devices. CONCLUSION: This research with vulnerable clients, from Tasmania, supports the evidence that the utilisation of telehealth allows more convenient access to care. To optimise the service, however, concerns regarding the desire for social interaction, appropriate physical examination, and access to fit-for-purpose telehealth devices will need to be addressed.

RESUMO

OBJECTIVE: The aim of this paper was to use current stroke care guidelines to identify and discuss current stroke care challenges in rural Australian health care and potential solutions for delivery of evidence-based practice. DESIGN AND SETTING: A review of national guidelines since 2002 for organised stroke care was undertaken to determine best practice for delivering primary stroke care. We then employed a narrative literature review strategy looking at relevant articles, based on keywords, outlining current stroke service availability in Australia, highlighting the challenges of implementing evidence-based stroke care in rural areas in Australia based on the current guidelines. RESULTS: Delivery of evidence-based stroke care in rural Australia is fraught with challenges. Although national best-practice guidelines for stroke care are well established, the recommendations made in these guidelines do not always reflect the resource availability in rural Australia. Redesigning processes and utilising available resources, such as telemedicine or local clinical pathways, can achieve an evidence-based standard; however, ultimately better resourcing of these areas is required. CONCLUSION: Evidence-based stroke care, aligned with current national standards is the key to providing adequate stroke services in rural Australia. Improved health service resourcing and better utilisation of currently available resources are options for achieving elements of evidence-based stroke care. IMPLICATIONS FOR PUBLIC HEALTH: Availability of adequate services for stroke patients directly impacts public health as it determines health outcomes for these patients. Indirect implications for public health include the effects on health professionals and the general public.

RESUMO

BACKGROUND: Previously developed in vitro cultures of the human retina have been solo or dual cell cultures. We developed a triple-cell culture in vitro model utilizing a membrane system to produce a better representation of a functional and morphological human retina. METHODS: Retinal microvascular endothelial cells (HRMVEC/ACBRI181, cell systems), retinal pigment epithelium cells (RPE/ARPE-19, ATCC) and Müller glial cells (Moorfield Institute of Ophthalmology-Müller 1, UCL) were grown in a triple culture. Our optimized triple-culture media contained a mix of specific endothelial medium and high glucose Dulbecco's Modified Eagle's medium, where all three layers were viable for up to 5 days. Co-culture effect on morphological changes (cell staining) and gene expression of functional genes (pigment epithelium derived factor [PEDF] and vascular endothelial growth factor [VEGF]) were measured from RNA via real-time polymerase chain reaction. Expression of tight junction protein 1 (TJP1) was measured in RNA isolated from ARPE-19s, to assess barrier stability. RESULTS: The triple-culture promotes certain cell functionality through up-regulation of TJP1, increasing PEDF and decreasing VEGF expression highlighting its importance for the assessment of disease mechanisms distinct from a solo culture which would not allow the true effect of the native microenvironment to be elucidated. CONCLUSIONS: This model's novelty and reliability allows for the assessment of singular cellular function within the retinal microenvironment and overall assessment of retinal health, while eliminating the requirement of animal-based models.

RESUMO

Healthcare redesign, based on building collaborative capacity between academic and clinical partners, should create a method to facilitate flow between the key elements of health service improvement. However, utilising the skills and resources of an organisation outside of the health facility may not always have the desired effect. Accountability and mutually respectful relationships are fundamental for collaborative, sustainable and successful completion of clinical research projects. This paper provides an academic perspective of both the benefits of academic involvement in facilitating healthcare redesign processes as well as the potential pitfalls of involving external partner institutions in internal healthcare redesign projects.

RESUMO

Diabetic kidney disease, or diabetic nephropathy (DN), is a major complication of diabetes and the leading cause of end-stage renal disease (ESRD) that requires dialysis treatment or kidney transplantation. In addition to the decrease in the quality of life, DN accounts for a large proportion of the excess mortality associated with type 1 diabetes (T1D). Whereas the degree of glycemia plays a pivotal role in DN, a subset of individuals with poorly controlled T1D do not develop DN. Furthermore, strong familial aggregation supports genetic susceptibility to DN. However, the genes and the molecular mechanisms behind the disease remain poorly understood, and current therapeutic strategies rarely result in reversal of DN. In the GEnetics of Nephropathy: an International Effort (GENIE) consortium, we have undertaken a meta-analysis of genome-wide association studies (GWAS) of T1D DN comprising ~2.4 million single nucleotide polymorphisms (SNPs) imputed in 6,691 individuals. After additional genotyping of 41 top ranked SNPs representing 24 independent signals in 5,873 individuals, combined meta-analysis revealed association of two SNPs with ESRD: rs7583877 in the AFF3 gene (P = 1.2 × 10(-8)) and an intergenic SNP on chromosome 15q26 between the genes RGMA and MCTP2, rs12437854 (P = 2.0 × 10(-9)). Functional data suggest that AFF3 influences renal tubule fibrosis via the transforming growth factor-beta (TGF-ß1) pathway. The strongest association with DN as a primary phenotype was seen for an intronic SNP in the ERBB4 gene (rs7588550, P = 2.1 × 10(-7)), a gene with type 2 diabetes DN differential expression and in the same intron as a variant with cis-eQTL expression of ERBB4. All these detected associations represent new signals in the pathogenesis of DN.

RESUMO

Community care encompasses inherent risks for both clients and healthcare providers. Maintaining a safe environment for the delivery of care services ensures that any risk of unintentional or intentional personal harm is minimised. The aim of this scoping review is to (a) provide an overview of existing knowledge by summarising the current literature and (b) identify gaps pertaining to understanding and managing environmental risk in community care settings. Guided by the Population/Concept/Context approach and PRISMA guidelines, this paper used two questions to answer how a score-based tool for assessing client suitability in community care is developed and how an environmental screening tool assists with reducing risk to community care workers. Literature searches of CINAHL, PubMed (Medline), Web of Science and PsychINFO databases were conducted between September 2023 and November 2023. We included full text articles published from 2018 to 2023. The following four broad areas were identified as key components in the structure of an environmental screening tool: environmental factors, health factors, socioeconomic factors and cultural factors. The results of this review provide valuable information which can be utilised by care organisations to develop and/or refine tools to ensure the safety and wellbeing of workers within the community care sector.

RESUMO

Stroke service delivery in rural areas in Australia lacks evidence-based, best practice care protocols as a result of limited resources and opportunity. Healthcare redesign is an approach to improving health services by understanding barriers and enablers to service provision and work with users to develop solutions for improvement. This research aimed to qualitatively evaluate stroke care in rural Tasmania using a person-centered approach, as part of a larger healthcare redesign initiative to improve acute stroke care. Semi-structured interviews, aimed at gaining insight into experiences of healthcare staff and users, were conducted. Thematic analysis revealed three global themes (communication, holistic care, and resourcing) that demonstrated some consistency between healthcare staff and user experience, highlighting that some needs and expectations were not being met. Results of this experiential study provide important perspectives for delivering needs-based improvements in service provision for acute stroke care. Overall, this study showed that systems of stroke care in rural areas could be improved by utilizing a redesign approach including healthcare staff and users in the development of solutions for health service improvement.

RESUMO

The post-stroke needs of young adults with stroke are not being met, as most resources are tailored to older people with stroke. This includes technology-based applications, which are being used more frequently in stroke rehabilitation. There is limited data on technology usage to support the unique needs of young adults with stroke in Australia. This study aimed to explore the unmet needs of young adults aged 18-30 years with stroke and ascertain how technology can help meet those needs to improve quality of life and participation. Sixteen in-depth semi-structured interviews were conducted with young adults with stroke (n = 10), healthcare professionals (n = 3) and caregivers of young adults with stroke (n = 3). The interviews were transcribed verbatim and analyzed inductively. Five themes were generated: 'Support for recovery', 'Availability of specific resources', 'Continuity of care', 'Adjustment' and 'Knowledge'. This study revealed the unique needs of young adults under 30 years with stroke who requested more targeted post-stroke support, age-specific resources and improved awareness on young stroke, with technology playing a pivotal role in all these interventions. We suggest co-designing technology-based solutions with young people after stroke to maximize their effectiveness in improving quality of life and participation in this unique cohort.

RESUMO

Overuse of computed tomography pulmonary angiograms (CTPAs) for diagnosis of pulmonary embolism (PE) has been recognised as an issue for over ten years, with Choosing Wisely Australia recommending that CTPAs only be ordered if indicated by a clinical practice guideline (CPG). This study aimed to explore the use of evidence-based practice within regional Tasmanian emergency departments in relation to CTPA orders by determining whether CTPAs were ordered in accordance with validated CPGs. We conducted a retrospective medical record review of all patients who underwent CTPA across all public emergency departments in Tasmania between 1 August 2018 and 31 December 2019 inclusive. Data from 2758 CTPAs across four emergency departments were included. PE was reported in 343 (12.4%) of CTPAs conducted, with yield ranging from 8.2% to 16.1% between the four sites. Overall, 52.1% of participants had neither a CPG documented, nor a D-dimer conducted before their scan. A CPG was documented before 11.8% of scans, while D-dimer was conducted before 43% of CTPAs. The findings presented in this study indicate that Tasmanian emergency departments are not consistently 'Choosing Wisely' when investigating PE. Further research is required to identify explanations for these findings.

RESUMO

BACKGROUND & AIMS: Alterations in the hormonal profiles as women transition to the menopause predisposes individuals to the metabolic syndrome (MetS). In post-menopausal women, this can be exacerbated by sedentary behaviour and physical inactivity. Physical activity can convey many health benefits including improvement in MetS risk factors. However, it remains to be elucidated how differing exercise intensities and its mode of delivery can ameliorate MetS risk factors and resultant progression amongst post-menopausal women. The purpose of this systematic review and meta-analysis was to investigate the effects and efficacy of exercise training on MetS risk factors in post-menopausal women. METHODS: Database searches using PubMed, Scopus, Web of Science and the Cochrane Central Register of Controlled Trials were conducted from inception to December 2021 for randomised controlled studies (RCTs) investigating exercise training (>8 weeks) in at least one of the MetS risk factors in post-menopausal women. Utilising the random-effects model, appropriate standardised mean differences (SMD) or mean differences (MD) with 95% confidence interval (CI) for each MetS risk factor were used to calculate the overall effect size between the exercise and control groups. Sub-group analyses were performed for exercise intensity, modality, and duration for each risk factor. Meta-regression was performed for categorical (health status) and continuous (body mass index) covariates. RESULTS: 39 RCTs (40 studies) involving 2132 participants were identified as eligible. Overall, the meta-analysis shows that exercise training significantly improved all MetS risk factors: waist circumference (WC) [MD: -2.61 cm; 95% CI: -3.39 to -1.86 cm; p < 0.001; 21 studies]; triglycerides (TG) [SMD: -0.40 mmol/L; 95% CI: -0.71 to -0.09 mmol/L; p = 0.01; 25 studies]; high-density lipoprotein (HDL) [SMD: 0.84 mmol/L (95% CI: 0.41-1.27 mmol/L; p < 0.001; 26 studies]; fasting glucose (BG) [SMD: -0.38 mmol/L (95% CI: -0.60 to -0.16 mmol/L; p < 0.001; 20 studies]; systolic blood pressure (SBP) [MD: -5.95 mmHg (95% CI: -7.98 to -3.92 mmHg; p < 0.001; 23 studies]; and diastolic blood pressure (DBP) [MD: -4.14 mmHg (95% CI: -6.19 to -2.08 mmHg; p < 0.001; 23 studies]. Furthermore, sub-group analyses identified that moderate intensity and combined exercise training significantly improved MetS risk factors (p < 0.05) except for HDL, with combined exercise being the most effective. Long duration (≥12 weeks) training also significantly improved MetS risk factors except for TG. Meta-regression revealed no moderating effects on any MetS risk variables. CONCLUSION: This study reinforces the importance of regular physical activity as a non-pharmacological tool in the reduction of MetS risk in post-menopausal women, with significant metabolic improvements seen in interventions spanning 8-10 weeks. Moderate intensity and combined training significantly benefitted abdominal obesity, dyslipidaemia, dysglycaemia and hypertension in post-menopausal women. Improvements in at least one MetS risk were also seen with other exercise modalities and intensities.

RESUMO

Mutations in fukutin-related protein (FKRP) are responsible for a common group of muscular dystrophies ranging from adult onset limb girdle muscular dystrophies to severe congenital forms with associated structural brain involvement. The defining feature of this group of disorders is the hypoglycosylation of α-dystroglycan and its inability to effectively bind extracellular matrix ligands such as laminin α2. However, α-dystroglycan has the potential to interact with a number of laminin isoforms many of which are basement membrane/tissue specific and developmentally regulated. To further investigate this we evaluated laminin α-chain expression in the cerebral cortex and eye of our FKRP knock-down mouse (FKRP(KD)). These mice showed a marked disturbance in the deposition of laminin α-chains including α1, α2, α4, and α5, although only laminin α1- and γ1-chain mRNA expression was significantly upregulated relative to controls. Moreover, there was a diffuse pattern of laminin deposition below the pial surface which correlated with an abrupt termination of many of the radial glial cells. This along with the pial basement membrane defects, contributed to the abnormal positioning of both early- and late-born neurons. Defects in the inner limiting membrane of the eye were associated with a reduction of laminin α1 demonstrating the involvement of the α-dystroglycan:laminin α1 axis in the disease process. These observations demonstrate for the first time that a reduction in Fkrp influences the ability of tissue-specific forms of α-dystroglycan to direct the deposition of several laminin isoforms in the formation of different basement membranes.

RESUMO

Pressure injury prevention is a significant issue as pressure injuries are difficult to heal, painful, and create clinical complications for patients. The aim of this study was to investigate knowledge and attitudes of first-year nursing students to pressure injury prevention, and to explore whether additional educational interventions augmented learning. A previously validated online survey was administered to three cohorts of first-year nursing students in 2016, 2017 (after additional online education), and 2018 (after further simulation education), and a subsequent comparative analysis was undertaken. Overall, the knowledge of students about pressure injury was low with measures to prevent pressure injury or shear achieving the lowest score (<50%). Students aged over 25 years (p < 0.001) and men (p = 0.14) gained higher attitude scores. There were significant differences for mean knowledge scores between the 2016 and 2018 cohorts (p = 0.04), including age group (p = 0.013) and number of clinical training units undertaken (p = 0.23). The 2016 cohort scored consistently lower in the attitude survey than both other cohorts (p < 0.001). Online resources and simulation experiences marginally improved knowledge and improved attitudes towards prevention of pressure injury. Nursing curricula should include targeted education to ensure student nurses are adequately prepared to prevent pressure injury through understanding of aetiology and risk assessment.

RESUMO

The objective of this study is to explore and understand the experiences of women who receive antenatal, birthing, and postnatal care from an integrated maternity services model in a regional area in Tasmania, Australia. This descriptive qualitative study included semi-structured, one-on-one interviews with 14 mothers aged >18 years, who were living in a regional area of Tasmania and had accessed maternity health services. Thematic analysis revealed three key themes: (i) talking about me, (ii) is this normal? and (iii) care practices. Overall, women cited mostly negative experiences from a poorly implemented fragmented service. These experiences included feelings of isolation, frustration over receiving conflicting advice, feeling ignored, and minimal to no continuity of care. In contrast, women also experienced the euphoric feelings of birth, immense support, guidance, and encouragement. Regional women's experiences of maternity care may be improved if health services work towards place-based continuity of care models. These models should be informed by the local women's experiences and needs in order to achieve better communication, reduce feelings of isolation, and promote positive breastfeeding experiences.

RESUMO

BACKGROUND: Online electronic records such as patient portals and personally controlled electronic health records (PEHRs) have been widely viewed as a key component to modernising the delivery of healthcare but the uptake of such systems has been slow. OBJECTIVE: The purpose of this literature review was to determine what influences consumers to engage and interact with their clinical data online. METHOD: A scoping literature review following PRISMA guidelines was completed. Electronic patient record research published between January 2009 and December 2018 was included. Following screening and full-text reviews, a total of 64 records were included in this review. RESULTS: Three key areas of influence on consumer engagement with their clinical data online emerged: demographic factors affecting consumer interaction with PEHRs; consumers' perceived benefits and detriments of PEHR use; and the influence of PEHR use on consumer empowerment and responsibility. DISCUSSION: Consumer motivation and readiness for engaging with their clinical data online and their long-term ongoing use of these systems requires further exploration. CONCLUSION: As worldwide rates of consumer interactions with individual online clinical data remain low, what influences consumer engagement with a PEHR remains unknown. Further research into the consumer perspective of, and interaction with, a PEHR, needs to be undertaken to determine if factors such as frequent usage of the system by consumers leads to improved clinical outcomes.

RESUMO

Computed tomography pulmonary angiography (CTPA) has become the most widely used technique for diagnosis or exclusion of a pulmonary embolism (PE). It has been suggested that overuse of this imaging type may be prevalent, especially in emergency departments (EDs). The purpose of this literature review was to explore the use of CTPAs in EDs worldwide. A review following PRISMA guidelines was completed, with research published between September 2010 and August 2020 included. Five key topics emerged: use of CTPAs; explanations for overuse; use of D-dimer; variability in ordering practices between clinicians; and strategies to reduce overuse. This review found that CTPAs continue to be overused in EDs, leading to superfluous risks to patients. Published studies identify that while clinical practice guidelines (CPGs) have a strong effect on reducing unnecessary CTPAs with no significantly increased risk of missed diagnosis, the adoption of these tools by ED clinicians has remained low. This literature review highlights the need for further research into why CTPAs continue to be overused within EDs and why clinicians are hesitant to use CPGs in the clinical setting. Moreover, investigations into other potential strategies that may combat the overuse of this diagnostic tool are essential to reduce potential harm.
