RESUMEN

End of life care is an essential part of the role of Australian aged care homes (ACHs). However, there is no national framework to support aged care staff in systematically identifying residents with palliative care needs or to routinely assess, respond to, and measure end of life needs. The Palliative Care Outcomes Collaboration (PCOC) is a national outcomes and benchmarking programme which aims to systematically improve palliative care for people who are approaching the end of life, and for their families and carers. The PCOC Wicking Model for Residential Aged Care was developed and piloted in four Australian ACHs. This paper reports on the qualitative findings from semi-structured interviews and focus groups conducted with ACH staff (N = 37) to examine feasibility. Thematic analysis identified three overarching themes about the pilot: (i) processes to successfully prepare and support ACHs; (ii) appropriateness of PCOC tools for the ACH setting; and (iii) realised and potential benefits of the model for ACHs. The lessons presented valuable insights to refine the PCOC Wicking Model and enrich understanding of the potential challenges and solutions for implementing similar programs within ACHs in future. The results suggest that key to successfully preparing ACHs for implementation of the PCOC Wicking Model is an authentic and well-paced collaborative approach with ACHs to ensure the resources, structures and systems are in place and appropriate for the setting. The PCOC Wicking Model for Residential Aged Care is a promising prototype to support ACHs in improving palliative and end of life care outcomes for residents and their carers.

RESUMEN

Objective: Client centered care (CCC) is strongly advocated for improving the quality of health care. The aim of the current study was to explore client and staff perspectives of a new model of CCC implemented in a residential alcohol and other drug (AOD) treatment service. Specifically, the study aimed to (i) describe the defining features of CCC, and (ii) describe the benefits and challenges of implementing CCC at the service. Methods: Participants were 18 clients and eight staff who took part in focus groups and interviews. Thematic analysis of four client focus groups and eight staff individual interviews was conducted. Results: Staff identified the defining features of CCC as flexible, comprehensive, open-minded, and inclusive. Clients and staff shared predominantly positive views on the CCC model. Shared themes included the challenge of balancing flexibility and structure, and delivering comprehensive and individualized care within the limits of staff knowledge, skills, and resources. Conclusions: Results suggest that implementing CCC across an AOD treatment setting has clear benefits to staff and clients, along with challenges that require careful consideration and planning. Future research should evaluate the effectiveness of providing guidelines that address many of the challenges associated with implementing CCC.

RESUMEN

BACKGROUND: International Classification of Disease (ICD) codes are central for identifying myocardial infarction (MI) in administrative hospitalisation data, however validation of MI subtype codes is limited. We measured the sensitivity and specificity of ICD-10-AM (Australian Modification) codes for ST-elevation MI (STEMI) and non-STEMI (NSTEMI). METHODS: A sample of MI admissions was obtained from a dataset containing all MI hospitalisations in Western Australia (WA) for 2003, 2008 and 2013. Clinical data were collected from hospital medical records (n=799 patients). Cases were classified by ICD-10-AM codes for STEMI, NSTEMI and unspecified MI, and compared to clinical classification from review of available electrocardiographs (ECGs) and cardiac biomarkers (n=660). Sensitivity and specificity for ICD-10-AM coding versus clinical classification was measured, stratified by calendar year of discharge. RESULTS: The majority of classifiable cases had MI recorded in the principal diagnosis field (STEMI n=293, 84.2%; NSTEMI n=202, 74.3%; unspecified MI n=20, 50.0%). Overall sensitivity of the ICD-10-AM STEMI code was 86.3% (95% CI 81.7-90.0%) and was higher when restricted to MI as a principal versus secondary diagnosis (88.8% vs 66.7%). Comparable values for NSTEMI were 66.7% (95% CI 61.5-71.6%), and 68.8% vs 61.4% respectively. Between 2003 and 2013, sensitivity for both MI subtypes increased: 80.2-89.5% for STEMI, and 51.2-73.8% for NSTEMI. Specificity was high for NSTEMI throughout (88.2% 95% CI 84.1-91.6%), although improving over time for STEMI (68.1-76.4%). CONCLUSIONS: The sensitivity and specificity of ICD-10-AM codes for MI subtypes in hospitalisation data are generally high, particularly for principal diagnosis cases. However, the temporal improvement in sensitivity in coding of MI subtypes, particularly NSTEMI, may necessitate modification to trend studies using administrative hospitalisation data.

RESUMEN

Background: Patient-centered care is strongly advocated as a key for improving the quality of healthcare. Research examining the impact of patient-centered care in healthcare has concluded that there are demonstrable albeit inconsistent relationships between patient experience, quality of care, and healthcare outcomes. Knowledge of the impact of patient-centered care in the treatment of substance use disorder is limited. The aim of this review was to assess relationships between indicators of patient-centered care (satisfaction and patient-reported experience measures) and patient outcomes (substance use, psychological wellbeing, and service use) among people attending treatment for substance use disorder. Methods: A systematic electronic literature search of a range of databases was conducted with variations of the search terms 'patient-centered care', 'substance use disorders', and residential or community specialist 'treatment'. The populations, interventions and outcomes were summarized and described according to the PRISMA statement. Results: A total of 25 articles were identified, of which only five included a patient-centered indicator other than satisfaction. Indicators of patient-centered care showed a generally positive association with improved outcomes, particularly between satisfaction with treatment and substance use. Nonetheless, mixed and contradictory results were not uncommon, more so for psychological wellbeing outcomes. Conclusions: There were demonstrable relationships between patient-centered indicators and outcomes for people receiving treatment for substance use disorder. However, conclusions are limited due to underrepresentation of patient-reported experience measures. Further research in the area is needed involving comparisons of patient centered indicators with outcomes and use of patient-reported experience measures together with satisfaction. Registration number: CRD42018092829.

RESUMEN

BACKGROUND: High resolution anoscopy (HRA) examination is regarded as the best method for the management of anal high grade squamous intraepithelial lesions to prevent anal squamous carcinoma. However, little is known about the acceptability of this procedure. This analysis looks at patient experience of HRA examination and ablative treatment under local anaesthetic. METHODS: Patients took part in anonymised feedback of their experience immediately after their HRA examinations and/or treatments. A standard questionnaire was used that included assessment of pain and overall satisfaction scores as well as willingness to undergo future HRA examinations. RESULTS: Four hundred four (89.4%) responses were received and all responses were analysed. The group consisted of 119 females (29.4%) and 261 males (64.6%) with median age of 45 years (IQR = 19) and 45 years (IQR = 21) respectively, and included 58 new cases, 53 treatment cases and 202 surveillance cases. 158 patients (39.1%) had at least one biopsy during their visits. The median pain score was 2 [Inter Quartile Range (IQR) 3] on a visual analogue scale of 0 to 10, where 0 indicated no pain / discomfort and 10 indicated severe pain. The median pain score was 2 (IQR 2) in men and 4 (IQR = 3) in women [Dunn's Test = 4.3, p < 0.0001] and 3 (IQR 4.5) in treatment cases. Problematic pain defined as a pain score of ≥7 occurred more frequently in women (14%) than in men (6%), [Chi square test (chi2) = 5.6, p = 0.02]. Patient satisfaction with the care they received, measured on a scale of 0 (not happy) to 10 (very happy) found the median score to be 10 with 76% reporting a score of 10. Out of 360 responses, 98% of women and 99% of men said that they would be willing to have a future HRA examination. CONCLUSIONS: In this cohort, the overall pain scores were low and similar across appointment types. However, women had a higher pain score, including troublesome pain levels. Despite this, both women and men were equally satisfied with their care and were willing to have a future examination. The results of the analysis show that the procedure is acceptable to patient groups. A small number of women may need general anaesthesia for their examinations/treatment.

RESUMEN

BACKGROUND: Heart rate variability (HRV) has emerged as a predictor of later cardiac risk. This study tested whether pregnancy complications that may have long-term offspring cardiac sequelae are associated with differences in HRV at birth, and whether these HRV differences identify abnormal cardiovascular development in the postnatal period. METHODS: Ninety-eight sleeping neonates had 5-min electrocardiogram recordings at birth. Standard time and frequency domain parameters were calculated and related to cardiovascular measures at birth and 3 months of age. RESULTS: Increasing prematurity, but not maternal hypertension or growth restriction, was associated with decreased HRV at birth, as demonstrated by a lower root mean square of the difference between adjacent NN intervals (rMSSD) and low (LF) and high-frequency power (HF), with decreasing gestational age (p < 0.001, p = 0.009 and p = 0.007, respectively). We also demonstrated a relative imbalance between sympathetic and parasympathetic tone, compared to the term infants. However, differences in autonomic function did not predict cardiovascular measures at either time point. CONCLUSIONS: Altered cardiac autonomic function at birth relates to prematurity rather than other pregnancy complications and does not predict cardiovascular developmental patterns during the first 3 months post birth. Long-term studies will be needed to understand the relevance to cardiovascular risk.

RESUMEN

BACKGROUND: Indigenous people experience poorer cancer survival outcomes compared with non-Indigenous people. Currently, there is growing awareness of poor health literacy as a determinant of cancer outcomes. However, little attention has been given to researching cancer-related health literacy amongst Indigenous people. OBJECTIVES: To systematically review empirical studies of cancer health literacy amongst Indigenous people worldwide. METHODS: Articles were identified in Medline (1946-2013); Pre-Medline; CINAHL; PsycINFO (1967-2013); PubMed; Current Contents/All Editions (1993-2013); Allied Health and Complimentary Medicine (1985-2013), and in the reference lists of retrieved articles and by expert consultation. 64 abstracts were screened for inclusion and 16 articles were retained. RESULTS: There is a paucity of high-quality research concerning of health literacy amongst Indigenous cancer patients. No articles used formal measures of health literacy and data on the prevalence of health literacy was not reported. Of the 7 articles describing interventions only one included a control group and the remainder employed quasi-experimental methods. CONCLUSIONS: Research is needed to explore the cultural relevance of existing measures of health literacy and to document the prevalence of health literacy amongst Indigenous people with cancer. A better understanding of Indigenous cancer patients' health literacy is required before health literacy interventions can be designed to improve Indigenous cancer outcomes.

RESUMEN

ABSTRACTObjective:The provision of psychological support to caregivers is an important part of the role of the clinical staff working in palliative care. Staff knowledge and attitudes may determine their openness to referring caregivers to a psychological intervention. We recently developed a self-help intervention for grief and psychological distress among caregivers and were interested in exploring the extent to which staff knowledge and attitudes might affect future implementation. The aims of our study were to: (1) examine the acceptability of self-help psychological intervention for caregivers among palliative care clinical staff; (2) examine potential attitudinal barriers toward prolonged grief disorder (PGD) as a diagnosis and interventions for grief; and (3) bolster staff confidence in skills and knowledge in identifying and managing caregiver psychological distress. METHOD: An anonymous survey was distributed among clinical staff at two inpatient units and two community health services that assessed the acceptability of self-help interventions for caregivers, attitudes about PGD diagnosis and grief intervention, and staff confidence in skills and knowledge in assessing caregiver psychological distress. RESULTS: Overall, clinical staff were positively oriented toward self-help for caregivers and intervention for grief. They were also basically confident in their skills and knowledge. While it was positive PGD attitudes that were associated with acceptability of self-help for caregivers, it was both positive and negative PGD attitudes that were associated more specifically with a willingness to refer caregivers to such an intervention. SIGNIFICANCE OF RESULTS: Our findings are useful in highlighting the issues to be considered in the implementation of a self-help intervention within the healthcare service. Clinical staff seemed positively oriented toward engaging with a psychological intervention for caregivers and likely to act as key allies in implementation.

RESUMEN

BackgroundAdults born very preterm have increased cardiac mass and reduced function. We investigated whether a hypertrophic phenomenon occurs in later preterm infants and when this occurs during early development.MethodsCardiac ultrasound was performed on 392 infants (33% preterm at mean gestation 34±2 weeks). Scans were performed during fetal development in 137, at birth and 3 months of postnatal age in 200, and during both fetal and postnatal development in 55. Cardiac morphology and function was quantified and computational models created to identify geometric changes.ResultsAt birth, preterm offspring had reduced cardiac mass and volume relative to body size with a more globular heart. By 3 months, ventricular shape had normalized but both left and right ventricular mass relative to body size were significantly higher than expected for postmenstrual age (left 57.8±41.9 vs. 27.3±29.4%, P<0.001; right 39.3±38.1 vs. 16.6±40.8, P=0.002). Greater changes were associated with lower gestational age at birth (left P<0.001; right P=0.001).ConclusionPreterm offspring, including those born in late gestation, have a disproportionate increase in ventricular mass from birth up to 3 months of postnatal age. These differences were not present before birth. Early postnatal development may provide a window for interventions relevant to long-term cardiovascular health.

RESUMEN

RATIONALE: Microparticles are cell-derived membrane vesicles, relevant to a range of biological responses and known to be elevated in cardiovascular disease. OBJECTIVE: To investigate microparticle release during cardiac stress and how this response differs in those with vascular disease. METHODS AND RESULTS: We measured a comprehensive panel of circulating cell-derived microparticles by a standardized flow cytometric protocol in 119 patients referred for stress echocardiography. Procoagulant, platelet, erythrocyte, and endothelial but not leukocyte, granulocyte, or monocyte-derived microparticles were elevated immediately after a standardized dobutamine stress echocardiogram and decreased after 1 hour. Twenty-five patients developed stress-induced wall motion abnormalities suggestive of myocardial ischemia. They had similar baseline microparticle levels to those who did not develop ischemia, but, interestingly, their microparticle levels did not change during stress. Furthermore, no stress-induced increase was observed in those without inducible ischemia but with a history of vascular disease. Fourteen patients subsequently underwent coronary angiography. A microparticle rise during stress echocardiography had occurred only in those with normal coronary arteries. CONCLUSIONS: Procoagulant, platelet, erythrocyte, and endothelial microparticles are released during cardiac stress and then clear from the circulation during the next hour. This stress-induced rise seems to be a normal physiological response that is diminished in those with vascular disease.

RESUMEN

BACKGROUND: Adult education institutions have been identified as potential settings to improve health literacy and address the health inequalities that stem from limited health literacy. However, few health literacy interventions have been tested in this setting. METHODS: Feasibility study for an RCT of the UK Skilled for Health Program adapted for implementation in Australian adult education settings. Implementation at two sites with mixed methods evaluation to examine feasibility, test for change in participants' health literacy and pilot test health literacy measures. RESULTS: Twenty-two socially disadvantaged adults with low literacy participated in the program and received 80-90 hours of health literacy instruction. The program received institutional support from Australia's largest provider of vocational education and training and was feasible to implement (100 % participation; >90 % completion; high teacher satisfaction). Quantitative results showed improvements in participants' health literacy skills and confidence, with no change on a generic measure of health literacy. Qualitative analysis identified positive student and teacher engagement with course content and self-reported improvements in health knowledge, attitudes, and communication with healthcare professionals. CONCLUSIONS: Positive feasibility results support a larger RCT of the health literacy program. However, there is a need to identify better, multi-dimensional measures of health literacy in order to be able to quantify change in a larger trial. This feasibility study represents the first step in providing the high quality evidence needed to understand the way in which health literacy can be improved and health inequalities reduced through Australian adult education programs.

RESUMEN

Our strengths-based model of coping with death and dying proposes acceptance and valued-living as key coping and appraisal strengths for the bereaved. These are core components of Acceptance and Commitment Therapy (ACT). The aim of this study was to provide an initial exploration of the theorized relationships via a survey of 97 bereaved university students. Using hierarchical regression analysis it was found that acceptance and valued-living were significant predictors of grief, while controlling for other model variables and loss characteristics. Results have implications for ACT-based approaches in supporting those bereaved who are struggling with their grief.

RESUMEN

BACKGROUND: Decision aids (DAs) are non-directive communication tools that help patients make value-consistent health-care decisions. However, most DAs have been developed without an explicit theoretical framework, resulting in a lack of understanding of how DAs achieve outcomes. OBJECTIVE: To investigate the effect of promoting affective vs. deliberative processing on DA effectiveness based on dual-process theory. DESIGN, SETTING AND PARTICIPANTS: One hundred and forty-eight female university students participated in a randomized controlled experiment with three conditions: emotion-focused, information-focused and control. Preference-value consistency, knowledge, decisional conflict and satisfaction were compared across the conditions using planned contrast analyses. INTERVENTION: The intervention comprised two different DAs and instructional manipulations. The emotion-focused condition received a modified DA with affective content and instructions to induce an affective reaction. The information-focused and control conditions received the same DA without the affective content. The information-focused condition received additional instructions to induce deliberative processing. RESULTS: Controlling for the experiment-wise error rate at P < 0.017, the emotion-focused and information-focused conditions had significantly higher decisional satisfaction than the control condition (P < 0.001). The emotion-focused condition did not demonstrate preference-value consistency. There were no significant differences for decisional conflict and knowledge. DISCUSSION: Results suggest that the promotion of affective processing may hinder value-consistent decision making, while deliberative processing may enhance decisional satisfaction. CONCLUSIONS: This investigation of the effect of affective and deliberative processes in DA-supported decision making has implications for the design and use of DAs. DA effectiveness may be enhanced by incorporating a simple instruction to focus on the details of the information.

RESUMEN

OBJECTIVE: Informal caregivers of palliative care patients play an essential role in the coordination of care for patients during their final phases of life. However, undertaking a caregiving role can have enduring psychological consequences for caregivers and interfere with functioning. Studies have investigated a variety of factors associated with individual differences in caregiver psychosocial outcomes, but little is known about their relative impact, and there is a need for guiding models to support research in this area. METHOD: A review of the literature was conducted on factors influencing the psychological distress and grief of caregivers. Drawing from acceptance and commitment therapy (ACT) and Stroebe and colleagues' integrative risk factor framework, we developed a process model to describe individual differences in caregiver psychological distress and grief. RESULTS: The model presents caregiver psychological distress and grief as functions of death attitudes and communication about death and dying, mediated by acceptance and valued living from an ACT perspective. An outline of the empirical and theoretical underpinnings for each component in the model is provided. SIGNIFICANT OF RESULTS: The presented model is an inherently strengths-based model that is concordant with acceptance- and values- (ACT) based interventions to facilitate coping in caregivers.

RESUMEN

BACKGROUND: Young adults born preterm have distinct differences in left ventricular mass, function, and geometry. Animal studies suggest that cardiomyocyte changes are evident in both ventricles after preterm birth; therefore, we investigated whether these young adults also have differences in their right ventricular structure and function. METHODS AND RESULTS: We studied 102 preterm-born young adults followed up prospectively since birth and 132 term-born control subjects born to uncomplicated pregnancies. We quantified right ventricular structure and function by cardiovascular magnetic resonance on a 1.5-T Siemens scanner using Argus and TomTec postprocessing software. Preterm birth was associated with a small right ventricle (end diastolic volume, 79.8±13.2 versus 88.5±11.8 mL/m(2); P<0.001) but greater right ventricular mass (24.5±3.5 versus 20.4±3.4 g/m2; P<0.001) compared with term-born controls, with the severity of differences proportional to gestational age (r=-0.47, P<0.001). Differences in right ventricular mass and function were proportionally greater than previously reported for the left ventricle. This was most apparent for systolic function; young adults born preterm had significantly lower right ventricular ejection fraction (57±8% versus 60±5%; P=0.006). Indeed, 21% had values below the lower limit observed in the term-born adults and 6% had mild systolic dysfunction (<45%). Postnatal ventilation accounted for some of the variation in mass but not function. CONCLUSIONS: Preterm birth is associated with global myocardial structural and functional differences in adult life, including smaller right ventricular size and greater mass. The changes are greater in the right ventricle than previously observed in the left ventricle, with potentially clinically significant impairment in right ventricular systolic function.

RESUMEN

BACKGROUND: Preterm birth leads to an early switch from fetal to postnatal circulation before completion of left ventricular in utero development. In animal studies, this results in an adversely remodeled left ventricle. We determined whether preterm birth is associated with a distinct left ventricular structure and function in humans. METHODS AND RESULTS: A total of 234 individuals 20 to 39 years of age underwent cardiovascular magnetic resonance. One hundred two had been followed prospectively since preterm birth (gestational age=30.3±2.5 week; birth weight=1.3±0.3 kg), and 132 were born at term to uncomplicated pregnancies. Longitudinal and short-axis cine images were used to quantify left ventricular mass, 3-dimensional geometric variation by creation of a unique computational cardiac atlas, and myocardial function. We then determined whether perinatal factors modify these left ventricular parameters. Individuals born preterm had increased left ventricular mass (66.5±10.9 versus 55.4±11.4 g/m(2); P<0.001) with greater prematurity associated with greater mass (r = -0.22, P=0.03). Preterm-born individuals had short left ventricles with small internal diameters and a displaced apex. Ejection fraction was preserved (P>0.99), but both longitudinal systolic (peak strain, strain rate, and velocity, P<0.001) and diastolic (peak strain rate and velocity, P<0.001) function and rotational (apical and basal peak systolic rotation rate, P =0.05 and P =0.006; net twist angle, P=0.02) movement were significantly reduced. A diagnosis of preeclampsia during the pregnancy was associated with further reductions in longitudinal peak systolic strain in the offspring (P=0.02, n=29). CONCLUSIONS: Individuals born preterm have increased left ventricular mass in adult life. Furthermore, they exhibit a unique 3-dimensional left ventricular geometry and significant reductions in systolic and diastolic functional parameters.

RESUMEN

Stress cardiomyopathy develops after abrupt sympathetic stimulation, likely from catecholamine-induced myocardial toxicity. The evolution of myocardial strain during and after an episode have not been previously characterized. We aimed to determine whether preexisting contractile abnormalities may explain the observed regional dysfunction during an acute episode and to investigate the persistence of strain abnormalities after clinical recovery. We identified patients who were diagnosed with stress cardiomyopathy and had an echocardiogram performed before their episode, during their episode, and within 1 year after. The diagnosis was confirmed based on the absence of obstructive coronary lesions. Left ventricular (LV) longitudinal strain was calculated using speckle-tracking software and compared between baseline, episode, and follow-up echocardiograms. The LV strain analysis was performed on 23 patients. The LV ejection fraction was 64 ± 8.7% at baseline, 45 ± 12% during the episode, and 5 9 ± 10% after a median follow-up of 46 days. The LV global longitudinal strain was 24 ± 4.7% at baseline, 11 ± 4.9% during the episode, and 19 ± 4.6% after the follow-up. The mean ejection fraction (p <0.01) and global longitudinal strain (p <0.001) remained below baseline levels at follow-up. Longitudinal strain was reduced (<18%) in 80 ± 23% of myocardial segments during an episode and 41 ± 21% of myocardial segments at follow-up. During the acute episode, 35 ± 6% of the abnormal segments were in the base, outside of the region of ballooning. Our findings suggests that stress cardiomyopathy is associated with global rather than regional myocardial injury and that contractile abnormalities persist after clinical improvement. These findings challenge our previous understanding of stress cardiomyopathy and may guide future pathophysiologic understanding of this complex disease.

RESUMEN

BACKGROUND: Global longitudinal strain (GLS) is a sensitive marker for identifying subclinical myocardial dysfunction in obstructive coronary artery disease (CAD). Little is known about the relationship between GLS and ischemia in patients with myocardial ischemia and no obstructive CAD (INOCA). OBJECTIVES: To investigate the relationship between resting GLS and ischemia on stress echocardiography (SE) in patients with INOCA. METHODS: Left ventricular GLS was calculated offline on resting SE images at enrollment (n = 144) and 1-year follow-up (n = 120) in the CIAO-ISCHEMIA (Changes in Ischemia and Angina over One year in International Study of Comparative Health Effectiveness with Medical and Invasive Approaches trial screen failures with no obstructive CAD on computed tomography [CT] angiography) study, which enrolled participants with moderate or severe ischemia by local SE interpretation (≥3 segments with new or worsening wall motion abnormality and no obstructive (<50% stenosis) on coronary computed tomography angiography. RESULTS: Global longitudinal strain values were normal in 83.3% at enrollment and 94.2% at follow-up. Global longitudinal strain values were not associated with a positive SE at enrollment (GLS = -21.5% positive SE vs GLS = -19.9% negative SE, P = .443) or follow-up (GLS = -23.2% positive SE vs GLS = -23.1% negative SE, P = .859). Significant change in GLS was not associated with positive SE in follow-up (P = .401). Regional strain was not associated with colocalizing ischemia at enrollment or follow-up. Changes in GLS and number of ischemic segments from enrollment to follow-up showed a modest but not clinically meaningful correlation (ß = 0.41; 95% CI, 0.16, 0.67; P = .002). CONCLUSIONS: In this cohort of INOCA patients, resting GLS values were largely normal and did not associate with the presence, severity, or location of stress-induced ischemia. These findings may suggest the absence of subclinical myocardial dysfunction detectable by echocardiographic strain analysis at rest in INOCA.

RESUMEN

BACKGROUND: Adolescents and young adults (AYAs) diagnosed with cancer experience physical, cognitive, and psychosocial effects from cancer treatment that can negatively affect their ability to remain engaged in education or work through cancer treatment and in the long term. Disengagement from education or work can have lasting implications for AYAs' financial independence, psychosocial well-being, and quality of life. Australian AYAs with cancer lack access to adequate specialist support for their education and work needs and report a preference for web-based support that they can access from anywhere, in their own time. However, it remains unclear what web-based resources exist that are tailored to support AYAs with cancer in reaching their educational or work goals. OBJECTIVE: This study aimed to determine what web-based resources exist for Australian AYAs with cancer to (1) support return to education or work and (2) identify the degree to which existing resources are age-specific, cancer-specific, culturally inclusive, and evidence-based; are co-designed with AYAs; use age-appropriate language; and are easy to find. METHODS: We conducted an environmental scan by searching Google with English search terms in August 2022 to identify information resources about employment and education for AYAs ever diagnosed with cancer. Data extraction was conducted in Microsoft Excel, and the following were assessed: understandability and actionability (using the Patient Education and Materials Tool), readability (using the Sydney Health Literacy Laboratory Health Literacy Editor), and whether the resource was easy to locate, evidence-based, co-designed with AYAs, and culturally inclusive of Aboriginal and Torres Strait Islander peoples. The latter was assessed using 7 criteria previously developed by members of the research team. RESULTS: We identified 24 web-based resources, comprising 22 written text resources and 12 video resources. Most resources (21/24, 88%) were published by nongovernmental organizations in Australia, Canada, the United States, and the United Kingdom. A total of 7 resources focused on education, 8 focused on work, and 9 focused on both education and work. The evaluation of resources demonstrated poor understandability and actionability. Resources were rarely evidence-based or co-designed by AYAs, difficult to locate on the internet, and largely not inclusive of Aboriginal and Torres Strait Islander populations. CONCLUSIONS: Although web-based resources for AYAs with cancer are often available through the websites of hospitals or nongovernmental organizations, this environmental scan suggests they would benefit from more evidence-based and actionable resources that are available in multiple formats (eg, text and audio-visual) and tailored to be age-appropriate and culturally inclusive.

RESUMEN

BACKGROUND: Discrepancies in cardiovascular care for women are well described, but few data assess the entire patient journey for chest pain care. OBJECTIVES: This study aimed to assess sex differences in epidemiology and care pathways from emergency medical services (EMS) contact through to clinical outcomes following discharge. METHODS: This is a state-wide population-based cohort study including consecutive adult patients attended by EMS for acute undifferentiated chest pain in Victoria, Australia (January 1, 2015, to June 30, 2019). EMS clinical data were individually linked to emergency and hospital administrative datasets, and mortality data and differences in care quality and outcomes were assessed using multivariable analyses. RESULTS: In 256,901 EMS attendances for chest pain, 129,096 attendances (50.3%) were women, and mean age was 61.6 years. Age-standardized incidence rates were marginally higher for women compared with men (1,191 vs 1,135 per 100,000 person-years). In multivariable models, women were less likely to receive guideline-directed care across most care measures including transport to hospital, prehospital aspirin or analgesia administration, 12-lead electrocardiogram, intravenous cannula insertion, and off-load from EMS or review by emergency department clinicians within target times. Similarly, women with acute coronary syndrome were less likely to undergo angiography or be admitted to a cardiac or intensive care unit. Thirty-day and long-term mortality was higher for women diagnosed with ST-segment elevation myocardial infarction, but lower overall. CONCLUSIONS: Substantial differences in care are present across the spectrum of acute chest pain management from first contact through to hospital discharge. Women have higher mortality for STEMI, but better outcomes for other etiologies of chest pain compared with men.
