ABSTRACT

OBJECTIVES: Only a small proportion of patients presenting to an ED with headache have a serious cause. The SNNOOP10 criteria, which incorporates red and orange flags for serious causes, has been proposed but not well studied. This project aims to compare the proportion of patients with 10 commonly accepted red flag criteria (singly and in combination) between patients with and without a diagnosis of serious secondary headache in a large, multinational cohort of ED patients presenting with headache. METHODS: Secondary analysis of data obtained in the HEAD and HEAD-Colombia studies. The outcome of interest was serious secondary headache. The predictive performance of 10 red flag criteria from the SNNOOP10 criteria list was estimated individually and in combination. RESULTS: 5293 patients were included, of whom 6.1% (95% CI 5.5% to 6.8%) had a defined serious cause identified. New neurological deficit, history of neoplasm, older age (>50 years) and recent head trauma (2-7 days prior) were independent predictors of a serious secondary headache diagnosis. After adjusting for other predictors, sudden onset, onset during exertion, pregnancy and immune suppression were not associated with a serious headache diagnosis. The combined sensitivity of the red flag criteria overall was 96.5% (95% CI 93.2% to 98.3%) but specificity was low, 5.1% (95% CI 4.3% to 6.0%). Positive predictive value was 9.3% (95% CI 8.2% to 10.5%) with negative predictive value of 93.5% (95% CI 87.6% to 96.8%). CONCLUSION: The sensitivity and specificity of the red flag criteria in this study were lower than previously reported. Regarding clinical practice, this suggests that red flag criteria may be useful to identify patients at higher risk of a serious secondary headache cause, but their low specificity could result in increased rates of CT scanning.

ABSTRACT

PURPOSE: To examine the relationship between guideline-concordant care (GCC) on the basis of national clinical practice guidelines and survival in children (0-14 years), adolescents and young adults (AYAs, 15-39 years), and adults (40 years and older) with osteosarcoma, and to identify sociodemographic and clinical factors associated with receipt of GCC and survival. METHODS: We used data from the California Cancer Registry (CCR) on patients diagnosed with osteosarcoma during 2004-2019, with detailed treatment information extracted from the CCR text fields, including chemotherapy regimens. Multivariable logistic and Cox proportional hazard regression were used for statistical analyses. RESULTS: Of 1,716 patients, only 47% received GCC, with variation by age at diagnosis: 67% of children, 43% of AYAs, and 30% of adults. In multivariable models, patients who received part or all care (v none) at specialized cancer centers were more likely to receive GCC. AYAs and adults were less likely to receive GCC than children (odds ratio [OR], 0.38 [95% CI, 0.30 to 0.50] and OR, 0.40 [95% CI, 0.28 to 0.56], respectively). In a model excluding adults, patients treated by pediatric (v medical) oncologists were more likely to receive GCC (OR, 3.44 [95% CI, 2.40 to 4.94]). Patients with metastatic osteosarcoma at diagnosis who did not receive GCC had a greater hazard of death (hazard ratio [HR], 2.02 [95% CI, 1.55 to 2.63]) but no statistical differences were found in those diagnosed at earlier stages (HR, 1.15 [95% CI, 0.92 to 1.43]). CONCLUSION: GCC was associated with improved survival in patients with metastatic osteosarcoma in California. However, we found disparities in the delivery of GCC, highlighting the need for target interventions to improve delivery of GCC in this patient population.

ABSTRACT

Importance: Hypertension is a major cause of cardiovascular disease, and although the Dietary Approaches to Stop Hypertension (DASH) diet lowers blood pressure (BP), adherence is typically low. Mindfulness training adapted to improving health behaviors that lower BP could improve DASH adherence, in part through improved interoceptive awareness relevant to dietary consumption. Objective: To evaluate the effects of the Mindfulness-Based Blood Pressure Reduction (MB-BP) program on interoceptive awareness and DASH adherence. Design, Setting, and Participants: Parallel-group, phase 2, sequentially preregistered randomized clinical trials were conducted from June 1, 2017, to November 30, 2020. Follow-up was 6 months. Participants with elevated unattended office BP (≥120/80 mm Hg) were recruited from the population near Providence, Rhode Island. Of 348 participants assessed for eligibility, 67 did not meet inclusion criteria, 17 declined, and 63 did not enroll prior to study end date. In total, 201 participants were randomly assigned, 101 to the MB-BP program and 100 to the enhanced usual care control group, with 24 (11.9%) unavailable for follow-up. Outcome assessors and the data analyst were blinded to group allocation. Analyses were performed using intention-to-treat principles from June 1, 2022, to August 30, 2023. Interventions: The 8-week MB-BP program was adapted for elevated BP, including personalized feedback, education, and mindfulness training directed to hypertension risk factors. Both MB-BP and control groups received home BP monitoring devices with instructions and options for referral to primary care physicians. The control group also received educational brochures on controlling high BP. Main Outcomes and Measures: The primary outcome was Multidimensional Assessment of Interoceptive Awareness (MAIA) questionnaire scores (range 0-5, with higher scores indicating greater interoceptive awareness), and the secondary outcome was DASH adherence scores assessed via a 163-item Food Frequency Questionnaire (range 0-11, with higher scores indicating improved DASH adherence), all compared using regression analyses. Results: Among 201 participants, 118 (58.7%) were female, 163 (81.1%) were non-Hispanic White, and the mean (SD) age was 60.0 (12.2) years. The MB-BP program increased the MAIA score by 0.54 points (95% CI, 0.35-0.74 points; P < .001; Cohen d = 0.45) at 6 months vs control. In participants with poor baseline DASH adherence, the MB-BP program also significantly increased the DASH score by 0.62 points (95% CI, 0.13-1.11 points; P = .01; Cohen d = 0.71) at 6 months vs controls. The intervention was also associated with a 0.34-point improvement in the DASH diet score in all MB-BP participants from baseline (95% CI, 0.09-0.59 points; P = .01; Cohen d = 0.27), while the control group showed a -0.04 point change in DASH diet score from baseline to 6 months (95% CI, -0.31 to 0.24 points; P = .78; Cohen d = -0.03). Conclusions and Relevance: A mindfulness program adapted to improving health behaviors to lower BP improved interoceptive awareness and DASH adherence. The MB-BP program could support DASH dietary adherence in adults with elevated BP. Clinical Trial Registration: ClinicalTrials.gov Identifiers: NCT03859076 and NCT03256890.

ABSTRACT

BACKGROUND AND OBJECTIVES: Curative intent therapy is the standard of care for early-stage hepatocellular carcinoma (HCC). However, these therapies are under-utilized, with several treatment and survival disparities. We sought to demonstrate whether the type of facility and distance from treatment center (with transplant capabilities) contributed to disparities in curative-intent treatment and survival for early-stage HCC in California. METHODS: We performed a retrospective analysis of the California Cancer Registry for patients diagnosed with stage I or II primary HCC between 2005 and 2017. Primary and secondary outcomes were receipt of treatment and overall survival, respectively. Multivariable logistic regression and Multivariable Cox proportional hazards regression were used to evaluate associations. RESULTS: Of 19 059 patients with early-stage HCC, only 36% (6778) received curative-intent treatment. Compared to Non-Hispanic White patients, Hispanic patients were less likely, and Asian/Pacific Islander patients were more likely to receive curative-intent treatment. Our results showed that rural residence, public insurance, lower neighborhood SES, and care at non-National Cancer Institute-designated cancer center were associated with not receiving treatment and decreased survival. CONCLUSIONS: Although multiple factors influence receipt of treatment for early-HCC, our findings suggest that early intervention programs should target travel barriers and access to specialist care to help improve oncologic outcomes.

ABSTRACT

PURPOSE: Breast cancer (BC) is the most common secondary cancer and has poorer survival than primary BC (pBC) after any prior malignancy. For BC survivors, developing a contralateral secondary BC (CSBC) is the most frequent second-cancer event and is currently treated similarly to pBC. Identifying survival differences between pBC and CSBC could influence future counseling and treatments for patients with CSBC. METHODS: Women (≥15 years) diagnosed with pBC from 1991 to 2015 in the California Cancer Registry (n = 377,176) were compared with those with CSBC (n = 15,586) by age group (15-39 years, n = 406; 40-64 years, n = 6814; ≥ 65 years, n = 8366). Multivariable logistic regression models assessed factors associated with CSBC. Multivariable Cox proportional hazards regression models assessed BC-specific survival (BCSS), while accounting for the competing risk of death. RESULTS: Across all ages, CSBC patients were more likely to have smaller tumors (T2 vs. T1a; 15-39 yeras: OR 0.25, CI 0.16-0.38; 40-64 years: OR 0.41, CI 0.37-0.45; ≥ 65 years: OR 0.46, CI 0.42-0.51) and lymph node-negative disease (positive vs. negative; 15-39 years: OR 0.86, CI 0.69-1.08; 40-64 years: OR 0.88, CI 0.83-0.93; ≥ 65 years: OR 0.89, CI 0.84-0.94). Additionally, CSBC was associated with worse survival compared with pBC across all ages (15-39 years: HR 2.73, CI 2.30-3.25; 40-64 years: HR 2.13, CI 2.01-2.26; ≥ 65 years: HR 1.52, CI 1.43-1.61). CONCLUSION: BCSS is worse among all women diagnosed with CSBC compared with pBC, with the strongest impact seen in adolescent and young adult women. Worse survival after CSBC, despite associations with smaller tumors and lymph node negativity, suggests that CSBC may need eventual treatment reconsideration.

ABSTRACT

We measured annual prevalence of microbiologically defined nontuberculous mycobacterial lung disease in Ontario, Canada. Mycobacterium avium prevalence was 13 cases/100,000 persons in 2020, a 2.5-fold increase from 2010, indicating a large increase in true M. avium lung disease. During the same period, M. xenopi decreased nearly 50%, to 0.84 cases/100,000 persons.

ABSTRACT

Background: Hypertension is a major cause of cardiovascular disease. The Dietary Approaches to Stop Hypertension (DASH) diet lowers blood pressure (BP). However, adherence is typically low. Mindfulness training adapted to improving health behaviors that lower BP could improve DASH adherence, in part through improved interoceptive awareness relevant to dietary consumption. The primary objective of the MB-BP trial was to evaluate effects of the Mindfulness-Based Blood Pressure Reduction (MB-BP) program on interoceptive awareness. Secondary objectives assessed whether MB-BP impacts DASH adherence, and explored whether interoceptive awareness mediates DASH dietary changes. Methods: Parallel-group phase 2 randomized clinical trial conducted from June 2017-November 2020 with 6 months follow-up. Data analyst was blinded to group allocation. Participants had elevated unattended office BP (≥120/80 mmHg). We randomized 201 participants to MB-BP (n=101) or enhanced usual care control (n=100). Loss-to-follow-up was 11.9%. Outcomes were the Multidimensional Assessment of Interoceptive Awareness (MAIA; range 0-5) score, and the DASH adherence score (range 0-11) assessed via a 163-item Food Frequency Questionnaire. Results: Participants were 58.7% female, 81.1% non-Hispanic white, with mean age 59.5 years. Regression analyses demonstrated that MB-BP increased the MAIA score by 0.54 (95% CI: 0.35,0.74; p<.0001) at 6 months follow-up vs. control. MB-BP increased the DASH score by 0.62 (95% CI: 0.13,1.11; p=0.01) at 6 months vs. control, in participants with poor DASH adherence at baseline. Conclusions: A mindfulness training program adapted to improving health behaviors that lower BP improved interoceptive awareness and DASH adherence. MB-BP could support DASH dietary adherence in adults with elevated BP. Clinical Trial Registration: Clinicaltrials.gov identifier NCT03859076 (https://clinicaltrials.gov/ct2/show/NCT03859076; MAIA) and NCT03256890 (https://clinicaltrials.gov/ct2/show/NCT03256890; DASH diet adherence).

ABSTRACT

Background Hypertension is a leading risk factor for cardiovascular disease. Despite availability of effective lifestyle and medication treatments, blood pressure (BP) is poorly controlled in the United States. Mindfulness training may offer a novel approach to improve BP control. The objective was to evaluate the effects of Mindfulness-Based Blood Pressure Reduction (MB-BP) versus enhanced usual care control on unattended office systolic BP. Methods and Results Methods included a parallel-group phase 2 randomized clinical trial conducted from June 2017 to November 2020. Follow-up time was 6 months. Outcome assessors and data analyst were blinded to group allocation. Participants had elevated unattended office BP (≥120/80 mm Hg). We randomized 201 participants to MB-BP (n=101) or enhanced usual care control (n=100). MB-BP is a mindfulness-based program adapted for elevated BP. Loss-to-follow-up was 17.4%. The primary outcome was change in unattended office systolic BP at 6 months. A total of 201 participants (58.7% women; 81.1% non-Hispanic White race and ethnicity; mean age, 59.5 years) were randomized. Results showed that MB-BP was associated with a 5.9-mm Hg reduction (95% CI, -9.1 to -2.8 mm Hg) in systolic BP from baseline and outperformed the control group by 4.5 mm Hg at 6 months (95% CI, -9.0 to -0.1 mm Hg) in prespecified analyses. Plausible mechanisms with evidence to be impacted by MB-BP versus control were sedentary activity (-350.8 sitting min/wk [95% CI, -636.5 to -65.1] sitting min/wk), Dietary Approaches to Stop Hypertension diet (0.32 score [95% CI, -0.04 to 0.67]), and mindfulness (7.3 score [95% CI, 3.0-11.6]). Conclusions A mindfulness-based program adapted for individuals with elevated BP showed clinically relevant reductions in systolic BP compared with enhanced usual care. Mindfulness training may be a useful approach to improve BP. Registration URL: https://www.clinicaltrials.gov; Unique identifiers: NCT03256890 and NCT03859076.

ABSTRACT

Cancer care (CC) is incredibly complex and requires the coordination of multiple disciplines for optimal outcomes. Historically, this has been accomplished with multidisciplinary tumor boards (MDTBs), but the benefits, while perhaps intuitive, have not always been demonstrated with sufficient research robustness and validity. We hypothesize that this difficulty in demonstrating the benefit of MDTBs may be related to a delay in decision-making and operationalizing those decisions. The history and value of MDTBs are presented as well as their weaknesses and limited demonstration of improved outcomes. A major weakness highlighted by the challenges of MDTBs is the concept of total package time (TPT) (rather, the inability to keep it as short as possible); any significant delays in CC for any discipline may have a deleterious impact on any given patient's care outcome. Drawing on our own experience with utilizing information and communication technology (ICT) during an effort to apply accountability theory to improve specifically radiation therapy package time (RTPT), we argue that similar principles will be applicable in the improvement of not only the TPT which relies on multiple disciplines, but other factors of CC as well, such as coordination. Experience with improvement in RTPT is discussed and the underlying theory is demonstrated as a sound methodology to apply beyond RTPT to TPT involving coordination of multiple disciplines and stands to lead to the full realization of the benefits of the multidisciplinary approach. The complexity of cancer means that real solutions to optimal outcomes are also, by nature, complex, but here simple accountability theory is demonstrated that may unlock the next phase of multidisciplinary coordination. In this work, we argue that the benefits of the MDTB format can be fully realized with the addition of ICT, a technological breakthrough in the past two decades, while not forgetting about continued human factors.

ABSTRACT

BACKGROUND: Through adequate screening and follow-up, cervical cancer can be prevented or detected at early-stage (stage I), which is related to excellent survival. Current guidelines recommend discontinuing screening for women ≥65 years with history of normal Pap and/or HPV tests, potentially leaving this age group vulnerable. This study examined late-stage disease in a population-based cohort. METHODS: Using California Cancer Registry data, we identified 12,442 patients ages ≥21 years with a first primary cervical cancer diagnosed during 2009-2018. Proportions of late-stage disease (stages II-IV) and early- and late-stage 5-year relative survival are presented by the age group. Among patients ages ≥65 years, multivariable logistic regression estimated associations of sociodemographic and clinical characteristics with late-stage cervical cancer. RESULTS: Nearly one fifth of patients (n = 2,171, 17.4%) were ≥65 years. More women ages ≥65 years (71%) presented with late-stage disease than younger women (48% in patients ages <65). Late-stage 5-year relative survival was lower for women ≥65 years (23.2%-36.8%) compared with patients <65 (41.5%-51.5%). Characteristics associated with late-stage cervical cancer in women ≥65 years included older age [odds ratio (OR), 1.02; 95% confidence interval (CI), 1.01-1.04; each year], non-adenocarcinoma histologic subtypes, and comorbidities (OR, 1.59; 95% CI, 1.21-2.08). CONCLUSIONS: There remains a significant burden of advanced cervical cancer in women ≥65. IMPACT: Efforts should be made to better understand how the current screening paradigm is failing women of 65 years and older. Future work should focus on determining past screening history, lapses in follow-up care, and non-invasive testing approaches.

ABSTRACT

Acute myeloid leukemia (AML) is an aggressive disease characterized by poor outcomes and therapy resistance. Devimistat is a novel agent that inhibits pyruvate dehydrogenase complex (PDH). A phase III clinical trial in AML patients combining devimistat and chemotherapy was terminated for futility, suggesting AML cells were able to circumvent the metabolic inhibition of devimistat. The means by which AML cells resist PDH inhibition is unknown. AML cell lines treated with devimistat or deleted for the essential PDH subunit, PDHA, showed a decrease in glycolysis and decreased glucose uptake due to a reduction of the glucose transporter GLUT1 and hexokinase II. Both devimistat-treated and PDHA knockout cells displayed increased sensitivity to 2-deoxyglucose, demonstrating reliance on residual glycolysis. The rate limiting gluconeogenic enzyme phosphoenolpyruvate carboxykinase 2 (PCK2) was significantly upregulated in devimistat-treated cells, and its inhibition increased sensitivity to devimistat. The gluconeogenic amino acids glutamine and asparagine protected AML cells from devimistat. Non-glycolytic sources of acetyl-CoA were also important with fatty acid oxidation, ATP citrate lyase (ACLY) and acyl-CoA synthetase short chain family member 2 (ACSS2) contributing to resistance. Finally, devimistat reduced fatty acid synthase (FASN) activity. Taken together, this suggests that AML cells compensate for PDH and glycolysis inhibition by gluconeogenesis for maintenance of essential glycolytic intermediates and fatty acid oxidation, ACLY and ACSS2 for non-glycolytic production of acetyl-CoA. Strategies to target these escape pathways should be explored in AML.

ABSTRACT

Importance: California's tobacco control efforts have been associated with a decrease in cancer mortality, but these estimates are based on smoking prevalence of the general population. Patient-level tobacco use information allows for more precise estimates of the proportion of cancer deaths attributable to smoking. Objective: To calculate the proportion (smoking-attributable fraction) and number (smoking-attributable cancer mortality) of cancer deaths attributable to tobacco use using patient-level data. Design, Setting, and Participants: The smoking-attributable fraction and smoking-attributable cancer mortality were calculated for a retrospective cohort of patients whose cancer was diagnosed from 2014 to 2019 with at least 1 year of follow-up using relative risks from large US prospective studies and patient-level smoking information. Follow-up continued through April 2022. A population-based cohort was identified from the California Cancer Registry. Participants included adults aged 20 years and older with a diagnosis of 1 of the 12 tobacco-related cancers (oral cavity or pharynx, larynx, esophagus, lung, liver, stomach, pancreas, kidney, bladder, colon or rectum, cervix, and acute myeloid leukemia). Exposures: Tobacco use defined as current, former, or never. Main Outcomes and Measures: The primary outcomes were the smoking-attributable fraction and smoking-attributable cancer mortality for each of the 12 tobacco-related cancers over 2 time periods (2014-2016 vs 2017-2019) and by sex. Results: Among 395 459 patients with a tobacco-related cancer, most (285 768 patients [72.3%]) were older than 60 years, the majority (228 054 patients [57.7%]) were non-Hispanic White, 229 188 patients were men (58.0%), and nearly one-half (184 415 patients [46.6%]) had lung or colorectal cancers. Nearly one-half of the deaths (93 764 patients [45.8%]) in the cohort were attributable to tobacco. More than one-half (227 660 patients [57.6%]) of patients had ever used tobacco, and 69 103 patients (17.5%) were current tobacco users, which was higher than the proportion in the general population (11.7%). The overall smoking-attributable fraction of cancer deaths decreased significantly from 47.7% (95% CI, 47.3%-48.0%) in 2014 to 2016 to 44.8% (95% CI, 44.5%-45.1%) in 2017 to 2019, and this decrease was seen for both men and women. The overall smoking-attributable cancer mortality decreased by 10.2%. Conclusions and Relevance: California still has a substantial burden of tobacco use and associated cancer. The proportion of cancer deaths associated with tobacco use was almost double what was previously estimated. There was a modest but significant decline in this proportion for overall tobacco-associated cancers, especially for women.

ABSTRACT

The Mycobacterium abscessus complex causes significant morbidity and mortality among patients with Cystic Fibrosis (CF). It has been hypothesized that these organisms are transmitted from patient to patient based on genomics. However, few studies incorporate epidemiologic data to confirm this hypothesis. We longitudinally sampled 27 CF and 7 non-CF patients attending a metropolitan hospital in Ontario, Canada from 2013 to 2018. Whole genome sequencing along with epidemiological data was used to evaluate the likelihood of transmission. Overall, the genetic diversity of M. abscessus was large, with a median pairwise distance (IQR) of 1,279 (143-134) SNVs between all Ontario M. abscessus isolates and 2,908 (21-3,204) single nucleotide variants (SNVs) between M. massiliense isolates. This reflects the global diversity of this pathogen, with Ontario isolates widely dispersed throughout global phylogenetic trees of each subspecies. Using a maximum distance of 25 SNVs as a threshold to identify possible transmission, we identified 23 (of 276 total) pairs of closely-related isolates. However, transmission was probable for only one pair based on both genomic and epidemiological data. This suggests that person-to-person transmission of M. abscessus among CF patients is indeed rare and reinforces the critical importance of epidemiological data for inferences of transmission.

ABSTRACT

Higher education institutions in low- and middle-income countries are increasingly offering post-graduate degree programmes in health informatics. An analysis of accredited Master of Science in Health Informatics (MSc HI) programmes in the East African Community (EAC), a common higher education and labor zone, revealed wide variability in covered courses and competencies. In this paper, we describe the process undertaken to harmonize and establish common benchmarks for MSc HI for the EAC, in collaboration with the Inter-University Council for East Africa (IUCEA). After a multi-step process involving desk-reviews, benchmarking workshop with stakeholders, and quality assurance of benchmarks by IUCEA, the MSc HI benchmarks were finalized. These benchmarks outline the MSc HI degree programme goal, objectives, admission criteria, graduation requirements, and expected Learning Outcomes (ELOs). The ELOs are further translated into courses covering all identified skills and competencies. The benchmarks should facilitate mobility of students, faculty and labor, and improve program quality.

ABSTRACT

OBJECTIVES: Pregnancy is defined as a 'red flag' in headache assessment. We aimed to describe the prevalence and causes of serious secondary headache in pregnant ED patients. METHODS: Unplanned secondary analysis of HEAD Study/HEAD Colombia data. RESULTS: 3.2% (117/3643) of ED headache patients aged 18-50 years were pregnant, of whom six (5.1%) had a serious secondary cause identified. The proportion of patients with serious headache causes was not significantly different between pregnant female, non-pregnant female and male patient subgroups (P = 0.89). CONCLUSION: Inclusion of pregnancy as a 'red flag' in ED headache assessment is not supported by these data.

ABSTRACT

OBJECTIVE: To inform local, state and national strategies intended to reduce demand for ED care, the present study aimed to identify key factors influencing the current provision of acute care within primary healthcare (PHC) and explore the policy and system changes potentially required. METHODS: Semi-structured interviews with key stakeholders were audio-recorded, transcribed verbatim and analysed through content and thematic approaches incorporating the Walt and Gilson health policy framework. RESULTS: Eleven interviews were conducted. Five key considerations were highlighted, namely the barriers and enablers for general practitioners (GPs) in providing acute care, barriers to patient use of PHC instead of ED, suggestions for new PHC models and improvements for current ED models. Additionally, economic issues relating to clinic funding and GP remuneration, complexities of state or federal funding and management of urgent care centres (UCC) were identified. Potential policy changes included GP clinics incorporating emergency appointments, GP triage, further patient streaming and changes to the ED medical workforce model, as well as linking hospitals with PHC clinics. Suggested system changes included improving rapid access to non-GP specialists, offering qualifications for urgent care within PHC, developing integrated information technology systems and educating patients regarding appropriate healthcare system pathways. CONCLUSION: The present study suggested that while PHC has the potential to attenuate the demands for ED services, a whole-of-system approach focusing on realignment of priorities and integrated changes are needed.

ABSTRACT

BACKGROUND: Safety culture in Emergency Departments (EDs) requires special attention due to unique operational feature of the ED environment. Which may influence a culture of patients' safety in the ED. OBJECTIVE: To identify the factors that influence patient safety culture in EDs. METHODS: A qualitative study using semi-structured interviews with 12 ED staff was carried out in two Australian EDs. The data was thematically analysed to identify and describe the factors perceived by staff as influencing patient safety culture. RESULTS: The findings revealed four super-ordinate themes and 19 categories. The themes were the following: (1) Environmental and Organisational; (2) Healthcare Professional (3) Managerial factors; and (4) Patients factors. CONCLUSIONS: Safety culture in the ED is influenced by complex set of factors. The results of this study may help ED workers with improving patient safety culture and healthcare quality in the ED.

ABSTRACT

BACKGROUND AND AIM: Migraine headache is commonly diagnosed in emergency departments (ED). There is relatively little real-world information about the epidemiology, investigation, management, adherence to therapeutic guidelines and disposition of patients treated in ED with a final diagnosis of migraine. The primary aim of the current study is to get a snapshot of assessment and management patterns of acute migraine presentations to the different settings of EDs with a view to raise awareness. METHODS: This is a planned sub-study of a prospective study conducted in 67 health services in 10 countries including Australia, New Zealand, Southeast Asia, Europe, and the UK investigating the epidemiology and outcome of adult patients presenting to ED with nontraumatic headache. Outcomes of interest for this study are demographics, clinical features (including severity), patterns of investigation, treatment, disposition, and outcome of patients diagnosed as having migraine as their final ED diagnosis. RESULTS: The cohort comprises 1,101 patients with a mean age of 39 years (SD ± 13.5; 73.7% [811]) were female. Most patients had had migraine diagnosed previously (77.7%). Neuroimaging was performed in 25.9% with a very low diagnostic yield or significant findings (0.07%). Treatment of mild migraine was in accordance with current guidelines, but few patients with moderate or severe symptoms received recommended treatment. Paracetamol (46.3%) and nonsteroidal anti-inflammatory drugs (42.7%) were the most commonly prescribed agents. Metoclopramide (22.8%), ondansetron (19.2%), chlorpromazine (12.8%), and prochlorperazine (12.8%) were also used. CONCLUSIONS: This study suggests that therapeutic practices are not congruent with current guidelines, especially for patients with severe symptoms. Efforts to improve and sustain compliance with existing management best practices are required.

ABSTRACT

A 4-y-old, female mixed-breed dog was presented to the Ontario Veterinary College for further evaluation of multiple pulmonary and hepatic masses, intrathoracic lymphadenitis, and recent development of a pyogranulomatous pleural effusion. Along with other comprehensive tests, a thoracic lymph node biopsy was performed, and Mycobacterium tuberculosis complex infection was confirmed by real-time PCR. The dog's condition declined post-operatively, and euthanasia was elected. Postmortem examination confirmed severe granulomatous pneumonia, hepatitis, intrathoracic and intraabdominal lymphadenitis, omentitis, and nephritis. Line-probe assays performed on samples collected postmortem confirmed the species as M. tuberculosis. 24-loci MIRU-VNTR genotyping, spoligotyping, and whole-genome sequencing revealed relations to known human isolates, but no epidemiologic link to these cases was investigated. Given the concern for potential human exposure during this animal's disease course, a public health investigation was initiated; 45 individuals were tested for M. tuberculosis exposure, and no subsequent human infections related to this animal were identified. Our case highlights the need for more readily available, minimally invasive testing for the diagnosis of canine mycobacteriosis, and highlights the ability of canid species to act as potential contributors to the epidemiology of M. tuberculosis infections.
