UNASSIGNED: To analyse changes in the use of paediatric (≤16 years) CT over the past decade and to evaluate the appropriateness of CT examinations at a tertiary teaching hospital.
UNASSIGNED: Data from 290 paediatric CTs were prospectively collected in 2022 and compared with data from 2017 (358 cases) and 2012 (538 cases). The justification of CTs was evaluated with regard to medical imaging referral guidelines and appropriateness rates were calculated.
UNASSIGNED: Paediatric CTs decreased 39.4% over the 10 years, contrasting with a 27.6% increase in overall CTs. Paediatric CTs as the share of overall CTs dropped from 2.5% in 2012 to 1.1% in 2022 (P < .0001), with a concurrent rise in paediatric MRIs (P < .0001). Notable reductions in CT use occurred for head trauma (P = .0003), chronic headache (P < .0001), epilepsy (P = .037), hydrocephalus (P = .0078), chest tumour (P = .0005), and whole-body tumour (P = .0041). The overall appropriateness of CTs improved from 73.1% in 2017 to 79.0% in 2022 (P = .0049). In 15.4% of the cases, no radiological examination was deemed necessary, and in 8.7% of the cases, another modality was more appropriate. Appropriateness rates were the highest for the head and neck angiography (100%) and the chest (96%) and the lowest for the neck (66%) and the head (67%).
UNASSIGNED: Justification of CT scans can be improved by regular educational interventions, increasing MRI accessibility, and evaluating the appropriateness of the requested CT before the examination. Interventions for a more effective implementation of referral guidelines are needed.
UNASSIGNED: The focus for improvement should be CTs for head and cervical spine trauma, accounting for the majority of inappropriate requests in the paediatric population.

Timely diagnosis of multiple sclerosis (MS) is a challenge due to factors such as prompt identification of symptoms and consequent delays in hospital visits and treatment initiation. In part to address this challenge, an expert scientific advisory panel of clinical nurse practitioners (CNPs) from different European nations was convened by Viatris on October 25, 2022, in Amsterdam, the Netherlands. This meeting was an interactive discussion to understand the role of clinical nurse practitioners in MS management. The objectives were to (1) understand the current delays in MS diagnosis from the perspective of expert CNPs; (2) determine the role of the CNP in MS management; and (3) identify the opportunities to improve accessibility, foster collaboration among stakeholders, and promote initiatives to educate people with MS. The recommendations of the panel underline the multidimensional role of CNPs in the management of MS at all stages. Health care stakeholders need to work together to achieve better access to treatment regimens and facilitate outcomes in the management of MS through shared decision-making and follow-ups. Further exploration of the role of CNPs in the management of MS, as well as recommendations for early diagnosis, will help both general practitioners and specialists better manage MS care.

OBJECTIVE: This study aimed to explore the perceptions of Meals on Wheels (MoWs) service users (SUs), and people who refer them to MoWs (\'referrers\'), with accessing and commencing the service in England, the barriers that might hinder service uptake, and what information would be valued when considering accessing the service.
METHODS: Semistructured interviews were conducted in May-July 2022 with seven SUs and 21 referrers, recruited from four MoWs providers across England. Data were analysed using inductive thematic analysis.
RESULTS: Participants indicated various pathways into the service, but referrers (family members) were more likely to be the ones enquiring about, and commencing, MoWs for SUs. Once an enquiry about MoWs had been made, the service was perceived as straightforward to set up. However, existing preconceptions and stereotypes were perceived to act as barriers to accessing MoWs. Information that participants deemed important to have available when deciding on whether to access MoWs related to the meals, the specific services provided, the reliability and flexibility of delivery and the cost of services.
CONCLUSIONS: These findings could inform MoWs service providers\' public awareness strategies about MoWs, to facilitate referrals to the service for adults with care and support needs.
UNASSIGNED: An advisory group of people with lived experience of MoWs (users of the service and their family referrers) extensively discussed the findings of the research and advised on the implications and future dissemination steps.

UNASSIGNED: In the United States, women are less likely to be referred, activated on the waitlist, or undergo kidney transplant (KT) than men; contemporary Canadian data regarding access to transplant for women are lacking.
UNASSIGNED: Among patients initiating dialysis in Nova Scotia (NS), Canada from 2010 to 2020, we examined the association of candidate gender with overall access to KT, including the following: (i) odds of transplant referral within 1 year of dialysis initiation, (ii) odds of activation on the transplant waitlist (if referred), and (iii) time-to-transplantation (if activated) using logistic regression or Cox proportional hazards models as appropriate.
UNASSIGNED: Among 749 patients deemed potentially eligible for transplant, women had lower transplant rates than men (adjusted hazard ratio [aHR]: 0.53, 95% confidence interval [CI]: 0.36-0.78); this was amplified among patients aged >60 years (aHR: 0.25, 95% CI: 0.09-0.69). Compared with men, women had a lower adjusted odds of transplant referral (adjusted odds ratio [aOR]: 0.57, 95% CI: 0.35-0.93) by 1 year after dialysis initiation. Among those referred, women had lower odds of waitlist activation than men (aOR: 0.58, 95% CI: 0.30-1.11); and among those activated, women had lower hazard of KT (aHR: 0.74, 95% CI: 0.51-1.09), though these differences were not statistically significant. Women in NS experience lower overall access to transplant, including less referral, activation and KT compared with men.
UNASSIGNED: Gender-based barriers to any of (or in this case each of) referral, activation, or transplantation result in inequities in access; identification of disparities at these critical decision points is an important first step toward ensuring equal access for all.

BACKGROUND: Determining whether a patient is eligible for kidney transplantation is complex. In this study, we estimate what proportion of patients with end-stage kidney disease (ESKD) might have been suitable candidates for kidney transplantation but were not referred.
METHODS: We identified 43,952 people initiating dialysis for kidney failure between 2012 and 2017 in the states of Georgia, North Carolina, or South Carolina from the United States Renal Data System and linked to the Early-Steps to Transplant Access Registry to obtain data on referral and waitlisting up until December 2020. We identified \'good transplant candidates\' as those who were waitlisted within 2-years of referral, among all patients referred within 1-year of dialysis initiation. Using propensity score cut-offs, logistic regression, and area under the curve (AUC), we then estimated the proportion of individuals who may have been good transplant candidates, but were not referred.
RESULTS: Overall, 42.6% of incident dialysis patients were referred within one year and among them, 32.9% were waitlisted within 2 years of referral. Our model had reasonably good discrimination for identifying good transplant candidates with an AUC of 0.70 (95%CI 0.69-0.71), sensitivity of 0.68 and specificity of 0.61. Overall, 25% of individuals not referred for transplant may have been \'good\' transplant candidates. Adding these patients to the existing 18,725 referred patients would increase the proportion of incident ESKD patients being referred within one year from 42.6% to 57.2% (a ~ 14.6% increase).
CONCLUSIONS: In this study, we show that a significant proportion of potentially good transplant candidates are not being referred for transplant. A ~ 14% increase in the proportion of patients being referred from dialysis facilities is both a meaningful and realistic goal and could lead to more qualified patients being referred and subsequently waitlisted for a lifesaving transplant.

BACKGROUND: Adults and children with cancer are referred to palliative care infrequently or late. Oncologists often gatekeep these referrals. Social exchange theory is used to explain physician referral behaviour in various clinical settings. Its utility in a cancer palliative care setting is not known.
METHODS: We used Karl Popper\'s hypothetico-deductive approach to test the hypothesis. The hypothesis was that social exchange theory is a helpful framework for explaining oncologists\' palliative care referral behaviour in a cancer setting. The utility of the theoretical framework was tested against the empiric findings of a systematic review and original research.
RESULTS: Most components of social exchange theory known to explain physician referral behaviour like beliefs about the provider or service, emotions triggered during the professional engagement, its symbolism and stigma, the complexity of the referral task, efforts needed to achieve it, its cost, benefit, and value were similar in a cancer setting. Empirical findings suggest that oncologists provided strategies and solutions to better palliative care integration instead of comparing their existing engagement with potential alternatives and choosing them.
CONCLUSIONS: Social exchange theory was found to be helpful in explaining oncologists\' palliative care referral behaviour. To further develop the social exchange theory based on the data used to test it, it is recommended to include feedback and solutions as a component of the theoretical framework alongside a comparison level for alternatives.

OBJECTIVE: In neonates with birth asphyxia (BA) and hypoxic-ischemic encephalopathy, therapeutic hypothermia (TH), initiated within six hours, is the only safe and established neuroprotective measure to prevent secondary brain injury. Infants born outside of TH centers have delayed access to cooling.
OBJECTIVE: To compare in-hospital mortality, occurrence of seizures, and functional status at discharge in newborns with BA depending on postnatal transfer for treatment to another hospital within 24 h of admission (transferred (TN) versus non-transferred neonates (NTN)).
METHODS: Nationwide retrospective cohort study from a comprehensive hospital dataset using codes of the International Classification of Diseases, 10th modification (ICD-10). Clinical and outcome information was retrieved from diagnostic and procedural codes. Hierarchical multilevel logistic regression modeling was performed to quantify the effect of being postnatally transferred on target outcomes.
METHODS: All discharges from German hospitals from 2016 to 2021.
METHODS: Full term neonates with birth asphyxia (ICD-10 code: P21) admitted to a pediatric department on their first day of life.
METHODS: Postnatal transfer to a pediatric department within 24 h of admission to an external hospital.
RESULTS: In-hospital death; secondary outcomes: seizures and pediatric complex chronic conditions category (PCCC) ≥ 2.
RESULTS: Of 11,703,800 pediatric cases, 25,914 fulfilled the inclusion criteria. TNs had higher proportions of organ dysfunction, TH, organ replacement therapies, and neurological sequelae in spite of slightly lower proportions of maternal risk factors. In TNs, the adjusted odds ratios (OR) for death, seizures, and PCCC ≥ 2 were 4.08 ((95% confidence interval 3.41-4.89), 2.99 (2.65-3.38), and 1.76 (1.52-2.05), respectively. A subgroup analysis among infants receiving TH (n = 3,283) found less pronounced adjusted ORs for death (1.67 (1.29-2.17)) and seizures (1.26 (1.07-1.48)) and inverse effects for PCCC ≥ 2 (0.81 (0.64-1.02)) in TNs.
CONCLUSIONS: This comprehensive nationwide study found increased odds for adverse outcomes in neonates with BA who were transferred to another facility within 24 h of hospital admission. Closely linking obstetrical units to a pediatric department and balancing geographical coverage of different levels of care facilities might help to minimize risks for postnatal emergency transfer and optimize perinatal care.

OBJECTIVE: The goal of this study was to investigate the impact of onset-to-cut time on mortality in patients undergoing surgery for stable acute type A aortic dissection.
METHODS: Patients who underwent surgery for acute type A aortic dissection between January 2006 and December 2021 and available onset-to-cut times were included. Patients with unstable aortic dissection (preoperative shock, intubation, resuscitation, coma, pericardial tamponade and local/systemic malperfusion syndromes) were excluded. After descriptive analysis, a multivariable binary logistic regression for 30-day mortality was performed. A receiver operating characteristic curve for onset-to-cut time and 30-day mortality was calculated. Restricted cubic splines were designed to investigate the association between onset-to-cut time and survival.
RESULTS: The final cohort comprised 362 patients. The median onset-to-cut time was 543 (376-1155) min. The 30-day mortality was 9%. Only previous myocardial infarction (P = 0.018) and prolonged cardiopulmonary bypass time (P < 0.001) were identified as independent risk factors for 30-day mortality. The corresponding area under the receiver operating characteristic curve showed a value of 0.49. Restricted cubic splines did not indicate an association between onset-to-cut time and survival (P = 0.316).
CONCLUSIONS: Onset-to-cut time in the setting of stable acute type A aortic dissection does not seem to be a valid predictor of 30-day mortality in patients undergoing surgery and stayed stable during the preoperative course.

OBJECTIVE: Patients referred to general internal medicine (GIM) outpatient clinics may face a higher risk of diagnostic errors than non-referred patients. This difference in risk is assumed to be due to the differences in diseases and clinical presentations between referred and non-referred patients; however, clinical data regarding this issue are scarce. This study aimed to determine the frequency of diagnostic errors and compare the characteristics of referred and non-referred patients visit GIM outpatient clinics.
METHODS: This study included consecutive outpatients who visited the GIM outpatient clinic at a university hospital, with or without referral. Data on age, sex, chief complaints, referral origin, and final diagnosis were collected from medical records. The Revised Safer Dx Instrument was used to detect diagnostic errors.
RESULTS: Data from 534 referred and 599 non-referred patients were analyzed. The diagnostic error rate was higher in the referral group than that in the non-referral group (2.2 % vs. 0.5 %, p=0.01). The prevalence of abnormal test results and sensory disturbances was higher in the chief complaints, and the prevalence of musculoskeletal system disorders, connective tissue diseases, and neoplasms was higher in the final diagnoses of referred patients compared with non-referred patients. Among referred patients with diagnostic errors, abnormal test results and sensory disturbances were the two most common chief complaints, whereas neoplasia was the most common final diagnosis. Problems with data integration and interpretation were found to be the most common factors contributing to diagnostic errors.
CONCLUSIONS: Paying more attention to patients with abnormal test results and sensory disturbances and considering a higher pre-test probability for neoplasms may prevent diagnostic errors in patients referred to GIM outpatient clinics.

OBJECTIVE: Behavioral sleep medicine (BSM) is a subspecialty that combines behavioral psychology and sleep medicine specialties. The objective of this study was to analyze referral patterns to a BSM clinic. The three specific aims were: (1) describe factors that predict referral acceptance, (2) identify barriers to attending initial appointment, and (3) describe variables associated with the number of visits attended.
METHODS: Retrospective chart reviews were conducted as part of a quality improvement project by this study team\'s clinical setting. Adults over 21 years of age who were referred to a behavioral sleep medicine clinic in an urban Midwestern academic healthcare system between 2014-2019 were included in this study.
RESULTS: Sleep medicine was the main referral source for BSM patients (74.2%), followed by internal medicine (9.3%) and neurology/psychiatry (7.3%). Thirty-eight percent of patients did not schedule an appointment after a referral for BSM was initiated. Younger age, longer distance from clinic, commercial insurance and out of network insurance were all significantly greater for non-schedulers. Eighty-three percent of patients did attend the initial intake session with BSM providers. Older age was associated with lower likelihood of not attending scheduled BSM appointments.
CONCLUSIONS: Patient characteristics of older age, closer distance from clinic, and in network insurance coverage were found to significantly increase the likelihood of BSM scheduling, while younger age, Black race and not getting a primary sleep disorder diagnosis (versus a diagnosis of Insomnia Disorder) and shorter days from referral to appointment were associated with an increased likelihood of not attending the scheduled BSM treatment engagement.
