Continuity of primary care and emergency department visits following knee and hip replacement surgery: a retrospective cohort study.

BACKGROUND: Continuity of primary care (CPC) improves patient well-being, but the association between CPC and surgical outcomes has not been well studied. The numbers of joint replacement procedures are expected to rise considerably in the coming years, so it is crucial to identify factors related to successful outcomes. The purpose of this study was to examine the association between CPC and emergency department (ED) visits after knee and hip replacement surgery. METHODS: Physician claims and hospital data from 2005 to 2020 in Nova Scotia were used in this retrospective study. To measure CPC, we used the Modified Modified Continuity Index (MMCI), which is the number of primary care providers adjusted for the total number of visits. The outcome was ED visits within 90 days of discharge. Logistic regression was used to test for associations between MMCI and the probability of an ED visit. RESULTS: There were 28 574 knee and 16 767 hip procedures in the data set; 13.9% (95% confidence interval [CI] 13.5%-14.3%) and 13.5% (95% CI 13.0%-14.0%) of the patients, respectively, had an ED visit within 90 days. For patients who underwent knee procedures, the mean MMCI was 0.868 (95% CI 0.867-0.870); 10.7% (95% CI 10.4 %-11.1 %) had perfect continuity of care. For patients who underwent hip procedures, the corresponding measures were 0.864 (95% CI 0.862-0.866) and 13.5% (95% CI 13.0%-14.0%). There was a statistically significant negative association between greater continuity of care and the probability of an ED visit after controlling for confounders. CONCLUSION: Having multiple primary care providers before surgery increased the likelihood of negative outcomes following knee or hip replacement surgery compared with having a single provider. Presurgical conversations should include primary care history to improve postsurgical outcomes.

Clinical Unmet Needs and Treatment Patterns of Paediatric Psoriasis Patients: A Real-World Evidence Study in Spain / Necesidades clínicas no satisfechas y patrones de tratamiento de los pacientes pediátricos con psoriasis: estudio de evidencia en el mundo real en España

Background and objective Real-world evidence of paediatric psoriasis (PsO) is lacking in Spain. The purpose of this study was to identify physician-reported disease burden and current treatment patterns in a real-world paediatric PsO patient cohort in Spain. This will enhance our understanding of the disease and contribute to the development of regional guidelines. Material and method This retrospective analysis of a cross-sectional market research survey assessed the clinical unmet needs and treatment patterns in patients with paediatric PsO in Spain, as reported by their primary care and specialist physicians, using data collected as part of the Adelphi Real World Paediatric PsO Disease-Specific Program (DSP™) between February and October 2020. Results Survey data from 57 treating physicians were included (71.9% [N=41] dermatologists, 17.6% [N=10] general practitioners/primary care physicians, and 10.5% [N=6] paediatricians); the final analysis included 378 patients. At sampling, 84.1% (318/378) of patients had mild disease, 15.3% (58/378) had moderate disease and 0.5% (2/378) had severe disease. Retrospectively reported physician-judged severity at the time of PsO diagnosis recorded 41.8% (158/378) of patients with mild disease, 51.3% (194/378) with moderate disease and 6.9% (26/378) with severe disease. Overall, 89.3% (335/375) of patients were currently receiving topical PsO therapy, while 8.8% (33/375), 10.4% (39/375) and 14.9% (56/375) of patients were currently receiving phototherapy, conventional systemics and biologics, respectively. Conclusions These real-world data reflect the current burden and treatment landscape of paediatric PsO in Spain. The management of patients with paediatric PsO could be improved by further educating healthcare professionals and developing regional guidelines (AU)

Outbreak of SARS-CoV-2 in a teenage discotheque in Northern Ireland-November 2021.

OBJECTIVES: To report key findings associated with an outbreak of SARS-CoV-2 following a teenage disco in Northern Ireland. STUDY DESIGN: Observational case series. METHODS: A case was defined as an individual who attended the event with a positive SARS-CoV-2 result between 6th and 20th November 2021. Demographic and clinical information, including symptom status, date of onset and school attended, were recorded during contact tracing. Vaccination status was derived from the COVID-19 Vaccine Management System. Forty-five samples associated with the outbreak were sequenced as part of the NI Whole Genome Sequencing (WGS) programme. RESULTS: Only 2.4% (5/205) of cases received a COVID-19 vaccine more than 14 days before the event. 84.9% (174/205) had received no vaccine at the time of the event and 12.7% (26/205) had been vaccinated within 14 days, offering only limited disease protection. The AY4.2.2 lineage of two cases who attended the event after symptom onset was found in 69% of sequenced outbreak cases. CONCLUSIONS: This study demonstrates extensive COVID-19 transmission in largely unvaccinated teenagers in an indoor venue with limited social distancing, close social contact and mixing, limited ventilation and singing and shouting. Public Health authorities developing COVID-19 entertainment regulations should consider congregations of teenagers in these settings, especially if vaccination rates are low in this group or they are not eligible for vaccination at that time. Public communications should be developed to ensure young people with COVID-19 symptoms follow public guidance regarding self-isolation and in particular avoid indoor events with larger numbers.

Covid-19 vaccine dissemination: A public health ethical evaluation of Pennsylvania's plan during Phase 1A.

Background: The novel COVID-19 pandemic afforded public health leaders an opportunity to expedite vaccine development and dissemination. The United States found itself faced with the arduous task of ensuring swift and equitable distribution of limited resources, in the midst of often-competing priorities, including public health ethics, medical ethics, economic demands, and societal strains. Methodology: Using the American Public Health Association's (APHA) newly revised public health code of ethics, which provides a decision-making framework and guidance for ethical analysis, we analyzed how Pennsylvania's COVID-19 vaccine dissemination plan aligned with the four core functions of public health ethics inquiry. Results/Discussion: Upon investigation, the state's plan evidenced use of public health ethics in goal setting and design. However, the core public health value given the highest priority, promoting health and safety, competed with the other core public health values of inclusivity and engagement, health justice and equity, and professionalism and trust. Despite known social disparities and risk factors, the state plan for COVID-19 vaccine dissemination aligned closely with federal guidance and prioritized all healthcare personnel and long-term care facility populations over high-risk individuals residing in the community. Conclusion/Perspectives: Should another pandemic necessitate allocation of scarce resources, especially preventative measures such as vaccines, decision-making agencies must consider disparate populations in planning and dissemination of material to the public. Any anticipated limitations in the ability to fulfill public health ethical principles should be clearly communicated to the public prior to implementation, thereby increasing trust.

Adverse reactions following transfusion of blood components, with a focus on some rare reactions: Reports to the International Haemovigilance Network Database (ISTARE) in 2012-2016.

OBJECTIVES: The International Haemovigilance Network's (IHN) ISTARE database collects surveillance data on all adverse reactions (AR) associated with transfusion of blood and blood components, facilitating the sharing of best practice and benchmarking for improving blood safety and quality. Up to 2012, no publications discussed certain rare AR. The aim of this study is to examine ISTARE data on AR from 2012 to 2016, focusing on hypotensive reactions, post-transfusion purpura (PTP), transfusion-associated graft versus host disease (TA-GvHD), hyperkalemia and hypocalcemia. MATERIALS AND METHODS: National Haemovigilance Systems (HVS), provided aggregate annual data on AR by type of reaction, severity, imputability to transfusion, and blood component implicated. Twenty-nine HVS provided 104 annual reports covering 107,778,290 blood units issued. RESULTS: Among AR reported, 25% were serious, including 368 deaths. The 284 transfusion-transmitted infections included 187 bacterial infections, 84 viral and 13 parasitic or fungal; nine deaths resulted. AR related to the respiratory system transfusion-associated circulatory overload, transfusion-related acute lung injury and transfusion-associated dyspnoea accounted for 8.3% of all AR, 20.1% of serious, and 52.2% of deaths. Of 1634 rare AR, 1565 were hypotensive, 38 PTP, 17 GvHD, 9 hyperkalemia and 5 hypercalcemia. Half were serious and 16 fatalities were recorded (13 hypotensive, 2 GvHD, one PTP). Among 14 countries that reported any hypotensive AR, incidences diverged widely. CONCLUSIONS: ARs in this group are frequently severe or life-threatening. Hypotensive AR are the most common, but may have been overlooked and counted under allergic and other AR presenting with hypotension. Compliance with the ISBT definition may be suboptimal, thus its real incidence may be higher. Data on GvHD may contribute to clarifying the role of leukodepletion with or without irradiation. ISTARE continues to be a useful surveillance tool for all transfusion AR and provides relevant insights into overlooked and rare AR, thus offering important contributions towards maximising transfusion safety.

Unmet clinical needs and burden of disease in hidradenitis suppurativa: real-world experience from EU5 and US.

BACKGROUND: Hidradenitis suppurativa (HS) is a chronic, inflammatory, debilitating skin disease characterized by painful deep lesions and associated with substantial disease burden. OBJECTIVES: The objective of this study was to describe physician- and patient-reported clinical unmet needs from a real-world perspective. METHODS: This study used data from the Adelphi HS Disease Specific Programme, a point-in-time survey of dermatologists and their patients with HS in Europe and the United States. Dermatologists completed patient record forms (PRFs) for 5-7 consecutively consulting patients with HS; patients or carers of patients also optionally completed a patient/carer self-completion questionnaire (PSC/CSC). Data collection included demographics, symptomatology and impact on quality of life (QoL). RESULTS: Dermatologists (N = 312) completed PRFs for 1787 patients with HS; patient- and carer-reported questionnaires (PSC/CSC) were completed for 33.1% (591/1787) of patients. The mean age was 34.4 ± 12.2 years and 57.6% of patients were female (1029/1787). Physician-judged disease severity at sampling was categorized as mild in 66.0% (1179/1787), moderate in 29.3% (523/1787) and severe in 4.7% (85/1787) of patients. Deterioration or unstable condition over the previous 12 months was described by 17.1% [235/1372] and 12.6% [41/325] of physician- and patient/carer-reported cases, respectively. Despite receiving treatment, high proportions of patients still experienced symptoms at sampling (general pain/discomfort [49.5%, 885/1787]; inflammation/redness of lesions/abscesses [46.1%, 823/1787] and itching [29.9%, 535/1787]); these symptoms were more frequent in patients with moderate or severe disease. Patients reported a mean Dermatology Life Quality Index score of 5.9 ± 5.4 (555/591; mild, 4.1 ± 4.3; moderate, 9.4 ± 5.4; severe, 13.3 ± 5.5) and a mean Hidradenitis Suppurativa Quality of Life score of 11.0 ± 10.6 (518/591; mild, 7.6 ± 8.3; moderate, 17.7 ± 10.0; severe, 31.0 ± 15.4) indicating a substantial impact on QoL. CONCLUSIONS: Patients with HS experienced a high disease burden despite being actively treated by a dermatologist. This study demonstrates that the burden of HS disease is generally poorly managed with a considerable impact observed on patients' QoL.

Validation of a Surgical Objective Structured Clinical Examination (S-OSCE) Using Convergent, Divergent, And Trainee-Based Assessments of Fidelity.

OBJECTIVE: Describe the validation of a surgical objective structured clinical examination (S-OSCE) for the purpose of competency assessment based on the Royal College of Canada's Can-MEDS framework. DESIGN: A surgical OSCE was developed to evaluate the management of common orthopedic surgical problems. The scores derived from this S-OSCE were compared to Ottawa Surgical Competency Operating Room Evaluation (O-SCORE), a validated entrustability assessment, to establish convergent validity. The S-OSCE scores were compared to Orthopedic In-Training Examination (OITE) scores to evaluate divergent validity. Resident evaluations of the clinical encounter with a standardized patient and the operative procedure were scored on a 10-point Likert scale for fidelity. SETTING: A tertiary level academic teaching hospital. PARTICIPANTS: 21 postgraduate year 2 to 5 trainees of a 5-year Canadian orthopedic residency program creating 160 operative case performances for review. RESULTS: There were 5 S-OSCE days, over a 4-year period (2016-2019) encompassing a variety of surgical procedures. Performance on the S-OSCE correlated strongly with the O-SCORE (Pearson correlation coefficient 0.88), and a linear regression analysis correlated moderately with year of training (R²â€¯= 0.5345). The Pearson correlation coefficient between the S-OSCE and OITE scores was 0.57. There was a significant increase in the average OITE score after the introduction of the surgical OSCE. Resident fidelity ratings were available from 16 residents encompassing 8 different surgical cases. The average score for the overall simulation (8.0±1.6) was significantly higher than the cadaveric surgical simulation (6.5 ± 0.8) (p < 0.001) CONCLUSIONS: The S-OSCE scores correlate strongly with an established form of assessment demonstrating convergent validity. The correlation between the S-OSCE and OITE scores was less, demonstrating divergent validity. Although residents rank the overall simulation highly, the fidelity of the cadaveric simulation may need improvement. Administration of a surgical OSCE can be used to evaluate preoperative and intraoperative decision making and complement other forms of assessment.

Reducing greenhouse gas emissions through genetic selection in the Australian dairy industry.

This research explores possible options to reduce greenhouse gas (GHG) emissions in the Australian dairy industry by (1) including an environmental component in the national breeding program and (2) estimating the economic and environmental impacts of implementation of the subsequent indexes. A total of 12 possible selection indexes were considered. These indexes were developed to predict changes in gross per-animal methane production (using 3 scenarios depending on availability and efficacy of a direct methane trait breeding value prediction) with 4 different carbon prices, integrating them into an augmentation of the current conventional national selection index. Although some economic response is lost with inclusion of the GHG subindexes in the Balanced Performance Index, options do exist where this loss is marginal and, even in scenarios where all selection pressure is based on the environmental weighting, economic progress is still made in all cases. When including environmental traits within an index, if a relatively low percentage of economic gain or index progression is sacrificed, then approximately 40 to 50% of the maximum possible reductions in emissions may be achieved. This concurrent selection of estimated breeding values that have a correlated favorable response in emissions in addition to direct selection on a residual methane trait allows a high level of methane reduction to be achieved with a realized cost to farmers that is far lower than the economic value placed on carbon. By implementing a GHG subindex in the national breeding program, we can achieve up to a 7.9% decrease in residual methane and 9 times the reduction in gross emissions in 10 yr, compared with the current breeding program, with little to no cost to farmers. By 2050, selection based on one of the more moderate index scenarios at a carbon price of AUD$250/t (AUD$1 = US$0.71), or opportunity cost to farmers of AUD$87.22, will reduce gross emissions by 8.23% and emissions intensity by 21.25%, therefore offering a mitigation strategy that will be effective at reducing emissions with little compromise to profit.

Weight-bearing in Trauma Surgery (WiTS) Study: A national survey of UK Trauma & Orthopaedic multidisciplinary health professionals.

INTRODUCTION: Weight-bearing (WB) status following a fracture or surgical fixation is an important determinant of the mechanical environment for healing. In order for healthcare professionals to communicate and understand the extent of bearing weight through a limb, clear terminology must be used. There is widespread variation in the usage and definitions of WB terminology in the literature and clinical practice. This study sought to define the understanding and extent of variation across the United Kingdom. METHODS: A nationwide online survey of UK-based Trauma & Orthopaedic (T&O) multidisciplinary healthcare professionals was conducted. Participants answered seven questions assessing their usage and understanding of various WB terminology. RESULTS: A total of 707 responses were received: 48% by doctors, 32% by physiotherapists, 13% by occupational therapists and 7% from other healthcare professionals. In terms of understanding of WB terminology with respect to percentage body weight (BW), 89% of respondents interpret 'full WB' as 100% BW, 97% interpret 'non WB' as 0% BW, 80% interpret 'partial WB' as 50% BW, and 89% interpret 'touch/toe-touch WB' as 10% or 20% BW. There were statistically significant differences between the responses of doctors and therapists for these four terms, with doctors tending to give higher %BW values. 'Protected WB' and 'WB as tolerated' had less consensus and more variability in responses. The majority (68%) of respondents do not usually quantify terminology such as 'partial WB' with a value, and 94% agreed that standardisation of WB terminology would improve communication amongst professionals. CONCLUSION: This study provides evidence of the substantial variation in the understanding of WB terminology amongst healthcare professionals, which likely results in ambiguous rehabilitation advice. Existing literature has shown that patients struggle to comply with terms such as 'partial weight-bearing'. We recommend consensus within the T&O multidisciplinary community to standardise and define common weight-bearing terminology.

Initiating home spirometry for children during the COVID-19 pandemic - A practical guide.

The COVID-19 pandemic has led to a rapid escalation in use of home monitoring and video consultations in children with a variety of chronic respiratory conditions. Our department set up a home spirometry service from scratch once it became evident that we needed to keep patients away from hospital clinics whenever possible. We faced a number of challenges but now have around 400 children using home spirometers. There are a number of portable spirometers available, some with online platforms. The technology, particularly the software/apps interface, has been improved by the companies in response to issues that have arisen. We believe the use of home monitoring is here to stay.

National population prevalence of antibodies to SARS-CoV-2 among pregnant women in Scotland during the second wave of the COVID-19 pandemic: a prospective national serosurvey.

OBJECTIVES: This study aimed to determine SARS-CoV-2 seroprevalence among pregnant women in the Scottish population during the second wave of the COVID-19 pandemic. STUDY DESIGN: Prospective national serosurvey. METHODS: We tested 13,428 residual samples retrieved from pregnant women participating in the first trimester combined ultrasound and biochemical screening for fetal trisomy across Scotland for SARS-CoV-2 antibodies over a 6-month period from November 2020 to April 2021. Seroprevalence estimates were adjusted for the sensitivity and specificity of the assays and weighted to reference populations. RESULTS: Seroprevalence rates in the antenatal samples significantly increased from 5.5% (95% confidence interval [CI] 4.7%-6.5%) in the 5-week period up to and including International Organization for Standardization (ISO) Week 51 (w/b Monday 14 December 2020) to 11.3% (95% CI 10.1%-12.6%) in the 5-week period up to and including ISO Week 14 (w/b Monday 5 April 2021). Increasing seroprevalence trends across the second wave were observed among all age groups. CONCLUSIONS: By the end of the second wave of the COVID-19 pandemic, approximately one in 10 women tested around the end of the first trimester of pregnancy had antibodies to SARS-CoV-2, suggesting that the vast majority were still susceptible to COVID-19 as they progressed to the later stages of pregnancy, when risks from infection are elevated for both mother and baby.

Estimating methane coefficients to predict the environmental impact of traits in the Australian dairy breeding program.

The dairy industry has been scrutinized for the environmental impact associated with rearing and maintaining cattle for dairy production. There are 3 possible opportunities to reduce emissions through genetic selection: (1) a direct methane trait, (2) a reduction in replacements, and (3) an increase in productivity. Our aim was to estimate the independent effects of traits in the Australian National Breeding Objective on the gross methane production and methane intensity (EI) of the Australian dairy herd of average genetic potential. Based on similar published research, the traits determined to have an effect on emissions include production, fertility, survival, health, and feed efficiency. The independent effect of each trait on the gross emissions produced per animal due to genetic improvement and change in EI due to genetic improvement (intensity value, IV) were estimated and compared. Based on an average Australian dairy herd, the gross emissions emitted per cow per year were 4,297.86 kg of carbon dioxide equivalents (CO2-eq). The annual product output, expressed in protein equivalents (protein-eq), and EI per cow were 339.39 kg of protein-eq and 12.67 kg of CO2-eq/kg of protein-eq, respectively. Of the traits included in the National Breeding Objective, genetic progress in survival and feed saved were consistently shown to result in a favorable environmental impact. Conversely, production traits had an unfavorable environmental impact when considering gross emissions, and favorable when considering EI. Fertility had minimal impact as its effects were primarily accounted for through survival. Mastitis resistance only affected IV coefficients and to a very limited extent. These coefficients may be used in selection indexes to apply emphasis on traits based on their environmental impact, as well as applied by governments and stakeholders to track trends in industry emissions. Although initiatives are underway to develop breeding values to reduce methane by combining small methane data sets internationally, alternative options to reduce emissions by utilizing selection indexes should be further explored.

A longitudinal investigation of sleep and technology use in early adolescence: does parental control of technology use protect adolescent sleep?

OBJECTIVE: A bi-directional relationship between technology use and adolescent sleep is likely, yet findings are mixed, and it is not known whether parental control of technology use can protect sleep. The current study examined bi-directionality between technology use on school nights and morning/eveningness, sleep duration and daytime sleepiness in early adolescents. We also examined whether time spent using technology mediated the relationship between parental control of technology and adolescent sleep. METHODS: Adolescents and their primary caregiver (96% mothers) completed questionnaire measures of sleep, technology use and parental control across three, annual waves: Wave 1 (N = 528, Mage = 11.18, SD = 0.56, range = 10-12, 51% male), Wave 2 (N = 502, Mage = 12.19, SD = 0.53, 52% male) and Wave 3 (N = 478, Mage = 13.19, SD = 0.53, 52% male). RESULTS: When examining the direct relationship between sleep and technology use, cross-lagged panel models showed that time spent using technology predicted shorter sleep duration and greater daytime sleepiness in adolescence, and evening diurnal preference and shorter sleep duration contributed to increased technology use over time. The relationship between technology use and sleep duration was bi-directional. Time spent using technology and adolescent sleep predicted, yet were not predicted by, parental control of technology use. CONCLUSIONS: While normative changes in sleep (eg, increased eveningness) may promote increased technology use, technology use may further impinge upon sleep. Results suggest it may be pertinent to instead find creative ways in which adolescents themselves can mitigate their risk of inadequate sleep.

Breeding for reduced methane emission and feed-efficient Holstein cows: An international response.

Selecting for lower methane (CH4) emitting animals is one of the best approaches to reduce CH4 given that genetic progress is permanent and cumulative over generations. As genetic selection requires a large number of animals with records and few countries actively record CH4, combining data from different countries could help to expedite accurate genetic parameters for CH4 traits and build a future genomic reference population. Additionally, if we want to include CH4 in the breeding goal, it is important to know the genetic correlations of CH4 traits with other economically important traits. Therefore, the aim of this study was first to estimate genetic parameters of 7 suggested methane traits, as well as genetic correlations between methane traits and production, maintenance, and efficiency traits using a multicountry database. The second aim was to estimate genetic correlations within parities and stages of lactation for CH4. The third aim was to evaluate the expected response of economically important traits by including CH4 traits in the breeding goal. A total of 15,320 methane production (MeP, g/d) records from 2,990 cows belonging to 4 countries (Canada, Australia, Switzerland, and Denmark) were analyzed. Records on dry matter intake (DMI), body weight (BW), body condition score, and milk yield (MY) were also available. Additional traits such as methane yield (MeY; g/kg DMI), methane intensity (MeI; g/kg energy-corrected milk), a genetic standardized methane production, and 3 definitions of residual methane production (g/d), residual feed intake, metabolic BW (MBW), BW change, and energy-corrected milk were calculated. The estimated heritability of MeP was 0.21, whereas heritability estimates for MeY and MeI were 0.30 and 0.38, and for the residual methane traits heritability ranged from 0.13 to 0.16. Genetic correlations between different methane traits were moderate to high (0.41 to 0.97). Genetic correlations between MeP and economically important traits ranged from 0.29 (MY) to 0.65 (BW and MBW), being 0.41 for DMI. Selection index calculations showed that residual methane had the most potential for inclusion in the breeding goal when compared with MeP, MeY, and MeI, as residual methane allows for selection of low methane emitting animals without compromising other economically important traits. Inclusion of residual feed intake in the breeding goal could further reduce methane, as the correlation with residual methane is moderate and elicits a favorable correlated response. Adding a negative economic value for methane could facilitate a substantial reduction in methane emissions while maintaining an increase in milk production.

The hidden dangers of staying home: a London trauma unit experience of lockdown during the COVID-19 virus pandemic.

INTRODUCTION: The COVID-19 pandemic resulted in reconfiguration of the NHS. Elective services were stopped and trauma services focused on decreasing patient-clinician interactions and managing injuries nonoperatively wherever possible. The everyday life of the general public changed dramatically with the introduction of a national lockdown to prevent the spread of COVID-19. This paper looks at the experience of a South West London trauma unit. MATERIALS AND METHODS: All patients reviewed in fracture clinic and by the orthopaedic on-call team between 23 March to 23 April 2020 were included. Data on the mechanism of injury and whether this was a usual activity, the injury sustained and its management were collected. RESULTS: A total of 167 trauma injuries were seen, compared with 735 new patients with injuries in the previous month. The number of trauma operations completed decreased by 38%; 55% of injuries occurred inside the home and 44% outside the home during daily exercise. Some 31% of injuries were secondary to a new activity taken up during lockdown. Three open fractures and two polytrauma cases were seen that would have normally been managed at the local major trauma centre. CONCLUSION: Overall, both the number of injuries seen and trauma operations completed during the enforced lockdown decreased. This is probably due to a change in the way the general public are living their lives, and the reconfigurations within the NHS in response to the COVID-19 pandemic. This is an interesting time within trauma and orthopaedic departments, as they continue to adapt to the changing injuries and working environment.

Paediatric sleep literacy in australian health professionals.

OBJECTIVE: This study aimed to provide the first estimate of sleep knowledge, practices, and attitudes regarding paediatric sleep in Australian health professionals. METHODS: 263 Australian health professionals (medical practitioners, nurses, psychologists, social workers, occupational therapists, pharmacists, dentists and sleep coaches) completed an anonymous survey. RESULTS: Clients with sleep disorders were commonly encountered by health professionals, yet professionals reported little time spent on clinical training in sleep medicine at the undergraduate (∼1-5 hrs) or postgraduate (∼0.5-3.5 hrs) level. Health professionals reported seeking continuing professional development (CPD) in sleep (∼6+ hrs), and CPD had the most influence on health professionals' practice, relative to other sources of information. Over half of health professionals (∼56-58%) reported that they were not trained in sleep measurement (i.e., sleep diaries and questionnaires), or how to take a sleep history. On average, professionals answered less than half (44.5%) of paediatric sleep knowledge questions correctly (M = 13.35, SD = 6.03). Approximately one third of health professionals reported not routinely screening for sleep disorders in paediatric patients and many did not routinely recommend evidence based treatments. The impact and importance of paediatric sleep was well recognised, but sleep was considered less important than a healthy diet and exercise. CONCLUSIONS: Results from the current study highlight key knowledge gaps regarding paediatric sleep across a wide range of Australian health professions, and may inform future efforts to reform clinical sleep medicine training in Australia.
