ABSTRACT

BACKGROUND: The critical role that middle managers play in enacting organisational culture change designed to address unprofessional co-worker behaviours has gone largely unexplored. We aimed to explore middle managers' perspectives on i) whether they speak up when they or their team members experience unprofessional behaviours (UBs); ii) how concerns are handled; iii) the outcomes; and iv) the role of a professional accountability culture change program (known as Ethos) in driving change. METHODS: Qualitative, constructivist approach. Five metropolitan hospitals in Australia which had implemented Ethos. Purposive sampling was used to invite middle-level managers from medicine, nursing, and non-clinical support services. Semi-structured interviews conducted remotely. Inductive, reflexive thematic and descriptive thematic analyses undertaken using NVivo. RESULTS: Thirty interviews (approximately 60 min; August 2020 to May 2021): Nursing (n = 12), Support Services (n = 10), and Medical (n = 8) staff, working in public (n = 18) and private (n = 12) hospitals. One-third (n = 10) had a formal role in Ethos. All middle managers (hearers) had experienced the raising of UBs by their team (speakers). Themes representing reasons for ongoing UBs were: staying silent but active; history and hierarchy; and double-edged swords. The Ethos program was valued as a confidential, informal, non-punitive system but required improvements in profile and effectiveness. Participants described four response stages: i) determining if reports were genuine; ii) taking action depending on the speaker's preference, behaviour factors (type, frequency, impact), if the person was known/unknown; iii) exploring for additional information; and iv) addressing either indirectly (e.g., change rosters) or directly (e.g., become a speaker). CONCLUSIONS: Addressing UBs requires an organisational-level approach beyond supporting staff to speak up, to include those hearing and addressing UBs. We propose a new hearer's model that details middle managers' processes after a concern is raised, identifying where action can be taken to minimise avoidant behaviours to improve hospital culture, staff and patient safety.

ABSTRACT

Objective: Women of childbearing age, including pregnant and breastfeeding women, report higher COVID-19 vaccine hesitancy, but reasons for this hesitancy are unknown. We explored factors influencing vaccine decision-making among women of childbearing age in Victoria, Australia to inform strategies to increase COVID-19 vaccine uptake. Methods: Twenty-four women aged 18-40 years were interviewed July-October 2021. Interview data were analyzed thematically using an inductive, constructivist approach. Results: Of 24 participants, 14 (57%) were vaccine-hesitant, of whom 10/14 pregnant or breastfeeding. Six key themes were identified: weighing up perceived risks for self and baby; availability of information; change and contradictions; vaccination above everything; practical issues - hurdles of inconvenience. Vaccine-hesitant women's concerns included safety in pregnancy, breastfeeding and fertility effects. Some participants expressed a loss of trust in healthcare providers following vaccine mandates. Conclusions: Public health campaigns and communication should be tailored to address specific concerns to increase COVID-19 vaccine uptake and prevent negative COVID-19 outcomes for women of childbearing age. Findings suggest that effective strategies to address hesitancy in this group may include providing robust short- and long-term safety data across fertility, birth outcomes and child development following COVID-19 vaccination. Other supportive strategies may include systemic changes like making childcare available at vaccination points (where practical), and using data linkage infrastructure to track post-vaccination outcomes.

ABSTRACT

Adolescent screen usage is ubiquitous and influences development and behavior. Longitudinal screen usage data coupled with psychometrically valid constructs of problematic behaviors can provide insights into these relationships. We describe methods by which the screen usage questionnaire was developed in the Adolescent Brain Cognitive Development (ABCD) Study, demonstrate longitudinal changes in screen usage via child report and describe data harmonization baseline-year 2. We further include psychometric analyses of adapted social media and video game addiction scales completed by youth. Nearly 12,000 children ages 9-10 years at baseline and their parents were included in the analyses. The social media addiction questionnaire (SMAQ) showed similar factor structure and item loadings across sex and race/ethnicities, but that item intercepts varied across both sex and race/ethnicity. The videogame addiction questionnaire (VGAQ) demonstrated the same configural, metric and scalar invariance across racial and ethnic groups, however differed across sex. Video gaming and online social activity increased over ages 9/10-11/12 (p's < 0.001). Compared with boys, girls engaged in greater social media use (p < .001) and demonstrated higher ratings on the SMAQ (p < .001). Compared with girls, boys played more video games (p < .001) and demonstrated higher ratings on the VGAQ (p < .001). Time spent playing video games increased more steeply for boys than girls from age 9/10-11/12 years (p < .001). Black youth demonstrated significantly higher SMAQ and VGAQ scores compared to all other racial/ethnic groups. These data show the importance of considering different screen modalities beyond total screen use and point towards clear demographic differences in use patterns. With these comprehensive data, ABCD is poised to address critical questions about screen usage changes across adolescence.

ABSTRACT

BACKGROUND: The Adolescent Brain Cognitive Development ™ Study (ABCD Study®) is an open-science, multi-site, prospective, longitudinal study following over 11,800 9- and 10-year-old youth into early adulthood. The ABCD Study aims to prospectively examine the impact of substance use (SU) on neurocognitive and health outcomes. Although SU initiation typically occurs during teen years, relatively little is known about patterns of SU in children younger than 12. METHODS: This study aims to report the detailed ABCD Study® SU patterns at baseline (n = 11,875) in order to inform the greater scientific community about cohort's early SU. Along with a detailed description of SU, we ran mixed effects regression models to examine the association between early caffeine and alcohol sipping with demographic factors, externalizing symptoms and parental history of alcohol and substance use disorders (AUD/SUD). PRIMARY RESULTS: At baseline, the majority of youth had used caffeine (67.6 %) and 22.5 % reported sipping alcohol (22.5 %). There was little to no reported use of other drug categories (0.2 % full alcohol drink, 0.7 % used nicotine, <0.1 % used any other drug of abuse). Analyses revealed that total caffeine use and early alcohol sipping were associated with demographic variables (p's<.05), externalizing symptoms (caffeine p = 0002; sipping p = .0003), and parental history of AUD (sipping p = .03). CONCLUSIONS: ABCD Study participants aged 9-10 years old reported caffeine use and alcohol sipping experimentation, but very rare other SU. Variables linked with early childhood alcohol sipping and caffeine use should be examined as contributing factors in future longitudinal analyses examining escalating trajectories of SU in the ABCD Study cohort.

ABSTRACT

The Adolescent Brain Cognitive Development (ABCD) Study® is a 10-year longitudinal study of children recruited at ages 9 and 10. A battery of neuroimaging tasks are administered biennially to track neurodevelopment and identify individual differences in brain function. This study reports activation patterns from functional MRI (fMRI) tasks completed at baseline, which were designed to measure cognitive impulse control with a stop signal task (SST; N = 5,547), reward anticipation and receipt with a monetary incentive delay (MID) task (N = 6,657) and working memory and emotion reactivity with an emotional N-back (EN-back) task (N = 6,009). Further, we report the spatial reproducibility of activation patterns by assessing between-group vertex/voxelwise correlations of blood oxygen level-dependent (BOLD) activation. Analyses reveal robust brain activations that are consistent with the published literature, vary across fMRI tasks/contrasts and slightly correlate with individual behavioral performance on the tasks. These results establish the preadolescent brain function baseline, guide interpretation of cross-sectional analyses and will enable the investigation of longitudinal changes during adolescent development.

ABSTRACT

Mobile and wearable technologies and novel methods of data collection are innovating health-related research. These technologies and methods allow for multi-system level capture of data across environmental, physiological, behavioral, and psychological domains. In the Adolescent Brain Cognitive Development (ABCD) Study, there is great potential for harnessing the acceptability, accessibility, and functionality of mobile and social technologies for in-vivo data capture to precisely measure factors, and interactions between factors, that contribute to childhood and adolescent neurodevelopment and psychosocial and health outcomes. Here we discuss advances in mobile and wearable technologies and methods of analysis of geospatial, ecologic, social network and behavioral data. Incorporating these technologies into the ABCD study will allow for interdisciplinary research on the effects of place, social interactions, environment, and substance use on health and developmental outcomes in children and adolescents.

ABSTRACT

BACKGROUND: Stroke telemedicine is widely used to treat patients with acute stroke in Europe and North America but is seldom used in Australia. The Victorian Stroke Telemedicine (VST) programme aims to enhance acute stroke care in regional Australia. METHODS: Twelve-month pilot prospective, historical-controlled, implementation cohort study. Emergency Department (ED) at a large regional hospital in Victoria. Patients ≥ 18 years of age arriving < 4.5 h in the ED with a possible diagnosis of acute stroke. Telemedicine consultation by a Melbourne-based stroke specialist. Stroke thrombolysis rate, timelines for clinical processes, discharge outcomes. RESULTS: In the initial 12 month VST implementation, 62 patients arrived < 4.5 h of stroke onset (60% male; median age 75 years). Compared to pre-VST data (n = 58; 52% male; median age 77 years), stroke thrombolysis use increased from 17% to 26% (P = 0.26). Clinical process timelines improved including door to computed tomography time (reduced by 29 min, P = 0.006), and door to needle time (reduced by 21 min, P = 0.21). There was no significant increase in deaths (pre-VST 7% vs VST 10%), or symptomatic intracerebral haemorrhage (n = 1 tPA patient). More patients who received tPA were discharged to home or rehabilitation (pre-VST 33% vs VST 80%, P = 0.02), with significantly fewer transfers to other acute care services. CONCLUSIONS: The VST pilot implementation provides evidence that telemedicine can enhance the quality of acute stroke care in a regional hospital. Expanding VST to 16 regional hospitals, Australia's largest telestroke programme, will allow for a more comprehensive clinical and economic analysis.

ABSTRACT

BACKGROUND: Fast diagnosis and delivery of treatment to patients experiencing acute stroke can reduce subsequent disability. While telemedicine can improve rural community access to specialists and facilitate timely diagnosis and treatment decisions, it is not widely used for stroke in Australia. AIM: Identifying the barriers and facilitators to clinician engagement with, and utilisation of, telemedicine consultations could expedite implementation in rural and remote locations. METHODS: Purposive sampling was used to identify and recruit medical and nursing staff varying in telemedicine experience across one hospital department. Twenty-four in-depth, face-to-face interviews were conducted examining aspects surrounding stroke telemedicine uptake. Inductive qualitative thematic analysis was undertaken, and two further researchers verified coding. RESULTS: The main barriers identified were contrasting opinions about the utility of thrombolysis for treating acute stroke, lack of confidence in the telemedicine system, perceived limited need for specialist advice and concerns about receiving advice from an unfamiliar doctor. Facilitators included assistance with diagnosis and treatment, the need for a user-friendly system and access to specialists for complex cases. CONCLUSIONS: Acceptability of telemedicine for acute stroke was multifaceted and closely aligned with regional clinician beliefs about the value of thrombolysis for stroke, highlighting an important area for education. Addressing beliefs about treatment efficacy and other perceived barriers is important for establishing a stroke telemedicine programme.

ABSTRACT

Sympathetically mediated urethral tone is essential for the maintenance of continence and involves the activation of postjunctional alpha(1)-adrenoceptors. This study characterizes the alpha(1)-adrenoceptor subtypes responsible for mediating contraction of the urethral circular smooth muscle of the pig. The potency order of a number of agonists and the affinities of several receptor selective antagonists were determined on pig-isolated circular smooth muscle strips in the presence of cocaine (1 microm) and corticosterone (10 microm) to inhibit amine uptake and propranolol (1 microm) to antagonize beta-adrenoceptors. The potency order for agonists was N-[5-(4,5-dihydro-1H-imidazol-2yl)-2-hydroxy-5,6,7,8-tetrahydronaphthalen-1-yl]methanesulphonamide (A61603) > noradrenaline = phenylephrine = M6434 > methoxamine with pEC(50) values of 7.3, 5.8, 5.7, 5.6 and 5.0 respectively. 4 The alpha(1D)-adrenoceptor-selective antagonist 8-[2-[4-(2-methoxyphenyl)-1-piperazinyl]ethyl]-8-azaspiro[4,5]decane-7,9-dione (BMY7378) caused rightward shifts of the concentration-response curves to noradrenaline, yielding a low affinity estimate (6.6) for the urethral receptor. The alpha(1A)-adrenoceptor-selective antagonists, RS100329 and 5-methylurapidil, gave relatively high affinity estimates (9.6 and 8.8 respectively) for this receptor. All three antagonists produced Schild plots with slopes close to unity but did reduce maximum responses at higher concentrations. Prazosin antagonized responses of the urethra to noradrenaline, yielding a mean affinity estimate of 9.0. Although the Schild plot for prazosin again had a slope of unity, this drug also reduced maximum responses to noradrenaline at all concentrations examined (10-100 nm). N-[2-(2-cyclopropylmethoxyphenoxy)ethyl]-5-chloro-alpha,alpha-dimethyl-1H-indole-3-ethanamide (RS17053), which discriminates between responses mediated via alpha(1A) (high affinity) and alpha(1L)-adrenoceptors (low affinity) at concentrations up to 3 microm, failed to antagonize responses of the urethra. 5 These results suggest that contraction of urethral circular smooth muscle in the pig is mediated via a single population of adrenoceptors with the pharmacological characteristics of the alpha(1A/L)-adrenoceptor, most probably the alpha(1L)-adrenoceptor.
