RESUMEN
OBJECTIVES: This scoping review mapped and synthesised original research that identified low-value care in hospital settings as part of multicomponent processes. DESIGN: Scoping review. DATA SOURCES: Electronic databases (EMBASE, PubMed, CINAHL, PsycINFO and Cochrane CENTRAL) and grey literature were last searched 11 July and 3 June 2022, respectively, with no language or date restrictions. ELIGIBILITY CRITERIA: We included original research targeting the identification and prioritisation of low-value care as part of a multicomponent process in hospital settings. DATA EXTRACTION AND SYNTHESIS: Screening was conducted in duplicate. Data were extracted by one of six authors and checked by another author. A framework synthesis was conducted using seven areas of focus for the review and an overuse framework. RESULTS: Twenty-seven records were included (21 original studies, 4 abstracts and 2 reviews), originating from high-income countries. Benefit or value (11 records), risk or harm (10 records) were common concepts referred to in records that explicitly defined low-value care (25 records). Evidence of contextualisation including barriers and enablers of low-value care identification processes were identified (25 records). Common components of these processes included initial consensus, consultation, ranking exercise or list development (16 records), and reviews of evidence (16 records). Two records involved engagement of patients and three evaluated the outcomes of multicomponent processes. Five records referenced a theory, model or framework. CONCLUSIONS: Gaps identified included applying systematic efforts to contextualise the identification of low-value care, involving people with lived experience of hospital care and initiatives in resource poor contexts. Insights were obtained regarding the theories, models and frameworks used to guide initiatives and ways in which the concept 'low-value care' had been used and reported. A priority for further research is evaluating the effect of initiatives that identify low-value care using contextualisation as part of multicomponent processes.

BACKGROUND: It is essential to consider the evidence of consumer preferences and their specific needs when determining which strategies to use to improve patient attendance at scheduled healthcare appointments. OBJECTIVES: This study aimed to identify key attributes and elicit healthcare consumer preferences for a healthcare appointment reminder system. METHODS: A discrete choice experiment was conducted in a general Australian population sample. The respondents were asked to choose between three options: their preferred reminder (A or B) or a 'neither' option. Attributes were developed through a literature review and an expert panel discussion. Reminder options were defined by four attributes: modality, timing, content and interactivity. Multinomial logit and mixed multinomial logit models were estimated to approximate individual preferences for these attributes. A scenario analysis was performed to estimate the likelihood of choosing different reminder systems. RESULTS: Respondents (n = 361) indicated a significant preference for an appointment reminder to be delivered via a text message (ß = 2.42, p < 0.001) less than 3 days before the appointment (ß = 0.99, p < 0.001), with basic details including the appointment cost (ß = 0.13, p < 0.10), and where there is the ability to cancel or modify the appointment (ß = 1.36, p < 0.001). A scenario analysis showed that the likelihood of choosing an appointment reminder system with these characteristics would be 97%. CONCLUSIONS: Our findings provide evidence on how healthcare consumers trade-off between different characteristics of reminder systems, which may be valuable to inform current or future systems. Future studies may focus on exploring the effectiveness of using patient-preferred reminders alongside other mitigation strategies used by providers.

Background: The financial burden resulting from cancers on families is higher when it arises in young people compared with older adults. Previous research has provided insight into the financial toxicities associated with childhood cancer, but less is known about the efficacy of financial aid systems in reducing the financial burden on families. We conducted a scoping review to identify the determinants of success and failure of financial aid. Methods: Five databases were searched for articles published between January 1, 2000 and December 1, 2022. Dual processes were used to screen and select studies. Through thematic content analysis, we identified barriers and enablers of financial aid, categorised by country income level. Results: From 17 articles, which were evenly split between high-income countries and upper middle- to low-income countries, four major themes emerged: (1) accessibility of support, (2) delivery of support, (3) administration, and (4) psychosocial factors. Within these themes, the enablers identified were (1) support navigators, (2) establishing a direct contact between donors and beneficiaries, (3) implementation of digital solutions to improve outreach, and (4) using cultural and community values to encourage donor engagement. Conclusions: This scoping review identified the determinants of success and failure of financial aid in supporting families in the context of childhood, adolescent, and young adult (CAYA) cancers. By understanding the barriers and enablers identified in this review, organizations could develop pragmatic evidence-based care models and policies to ensure access to assistance is equitable and appropriate for families experiencing CAYA cancers.

BACKGROUND: Computerized clinical decision support systems (CDSSs) are essential components of modern health system service delivery, particularly within acute care settings such as hospitals. Theories, models, and frameworks may assist in facilitating the implementation processes associated with CDSS innovation and its use within these care settings. These processes include context assessments to identify key determinants, implementation plans for adoption, promoting ongoing uptake, adherence, and long-term evaluation. However, there has been no prior review synthesizing the literature regarding the theories, models, and frameworks that have informed the implementation and adoption of CDSSs within hospitals. OBJECTIVE: This scoping review aims to identify the theory, model, and framework approaches that have been used to facilitate the implementation and adoption of CDSSs in tertiary health care settings, including hospitals. The rationales reported for selecting these approaches, including the limitations and strengths, are described. METHODS: A total of 5 electronic databases were searched (CINAHL via EBSCOhost, PubMed, Scopus, PsycINFO, and Embase) to identify studies that implemented or adopted a CDSS in a tertiary health care setting using an implementation theory, model, or framework. No date or language limits were applied. A narrative synthesis was conducted using full-text publications and abstracts. Implementation phases were classified according to the "Active Implementation Framework stages": exploration (feasibility and organizational readiness), installation (organizational preparation), initial implementation (initiating implementation, ie, training), full implementation (sustainment), and nontranslational effectiveness studies. RESULTS: A total of 81 records (42 full text and 39 abstracts) were included. Full-text studies and abstracts are reported separately. For full-text studies, models (18/42, 43%), followed by determinants frameworks (14/42,33%), were most frequently used to guide adoption and evaluation strategies. Most studies (36/42, 86%) did not list the limitations associated with applying a specific theory, model, or framework. CONCLUSIONS: Models and related quality improvement methods were most frequently used to inform CDSS adoption. Models were not typically combined with each other or with theory to inform full-cycle implementation strategies. The findings highlight a gap in the application of implementation methods including theories, models, and frameworks to facilitate full-cycle implementation strategies for hospital CDSSs.

BACKGROUND: In a therapeutic partnership, physicians rely on patients to describe their health conditions, join in shared decision-making, and engage with supported self-management activities. In shared care, the patient, primary care, and specialist services partner together using agreed processes and outputs for the patient to be placed at the centre of their care. However, few empirical studies have explored physicians' trust in patients and its implications for shared care models. AIM: To explore trust in patients amongst general practitioners (GPs), and the impacts of trust on GPs' willingness to engage in new models of care, such as colorectal cancer shared care. METHODS: GP participants were recruited through professional networks for semi-structured interviews. Transcripts were integrity checked, coded inductively, and themes developed iteratively. RESULTS: Twenty-five interviews were analysed. Some GPs view trust as a responsibility of the physician and have a high propensity for trusting patients. For other GPs, trust in patients is developed over successive consultations based on patient characteristics such as honesty, reliability, and proactivity in self-care. GPs were more willing to engage in colorectal cancer shared care with patients with whom they have a developed, trusting relationship. CONCLUSIONS: Trust plays a significant role in the patient's access to shared care. The implementation of shared care should consider the relational dynamics between the patient and health care providers.
In a therapeutic partnership, physicians rely on patients to describe their health conditions, join in shared decision-making and engage with supported self-management activities. In shared care, the patient, primary care, and specialist services partner together using agreed processes and outputs for the patient to be placed at the centre of their care. Trust is key to this partnership. However, few studies have explored the physicians' trust in patients and its implications for shared care models. This study aims to explore trust in patients amongst general practitioners (GPs), and the impacts of trust on GPs' willingness to engage in new models of care, such as colorectal cancer shared care. After analysing 25 interview transcripts with GPs, we found some GPs view trust as a responsibility of the physicians, while in others, trust in patients developed over successive consultations based on patient characteristics such as honesty, reliability, and proactivity in self-care. GPs were more willing to engage in colorectal cancer shared care with patients whom they have a developed, trusting relationship. Trust plays a significant role in the patient's access to shared care. The rollout of shared care should consider the relational dynamics between the patient and health care providers.
RESUMEN
BACKGROUND: Successful implementation and utilization of Computerized Clinical Decision Support Systems (CDSS) in hospitals is complex and challenging. Implementation science, and in particular the Nonadoption, Abandonment, Scale-up, Spread and Sustainability (NASSS) framework, may offer a systematic approach for identifying and addressing these challenges. This review aimed to identify, categorize, and describe barriers and facilitators to CDSS implementation in hospital settings and map them to the NASSS framework. Exploring the applicability of the NASSS framework to CDSS implementation was a secondary aim. METHODS: Electronic database searches were conducted (21 July 2020; updated 5 April 2022) in Ovid MEDLINE, Embase, Scopus, PyscInfo, and CINAHL. Original research studies reporting on measured or perceived barriers and/or facilitators to implementation and adoption of CDSS in hospital settings, or attitudes of healthcare professionals towards CDSS were included. Articles with a primary focus on CDSS development were excluded. No language or date restrictions were applied. We used qualitative content analysis to identify determinants and organize them into higher-order themes, which were then reflexively mapped to the NASSS framework. RESULTS: Forty-four publications were included. These comprised a range of study designs, geographic locations, participants, technology types, CDSS functions, and clinical contexts of implementation. A total of 227 individual barriers and 130 individual facilitators were identified across the included studies. The most commonly reported influences on implementation were fit of CDSS with workflows (19 studies), the usefulness of the CDSS output in practice (17 studies), CDSS technical dependencies and design (16 studies), trust of users in the CDSS input data and evidence base (15 studies), and the contextual fit of the CDSS with the user's role or clinical setting (14 studies). Most determinants could be appropriately categorized into domains of the NASSS framework with barriers and facilitators in the "Technology," "Organization," and "Adopters" domains most frequently reported. No determinants were assigned to the "Embedding and Adaptation Over Time" domain. CONCLUSIONS: This review identified the most common determinants which could be targeted for modification to either remove barriers or facilitate the adoption and use of CDSS within hospitals. Greater adoption of implementation theory should be encouraged to support CDSS implementation.

INTRODUCTION: This cluster-randomized controlled trial aimed to assess the effect of the "Which test is best?" tool on risk-appropriate screening (RAS) and colorectal cancer (CRC) screening uptake. METHODS: General practices in Sydney and Melbourne, Australia, and a random sub-sample of 460 patients (aged 25-74 years) per practice were invited by post. Clusters were computer randomized independently of the researchers to an online CRC risk calculator with risk-based recommendations versus usual care. Primary and secondary outcomes were RAS and screening uptake via self-reported 5-year screening behaviour after 12 months follow-up. The usual care group (UCG) also self-reported 5-year CRC screening behaviour at 12 month post-randomization. RESULTS: Fifty-six practices were randomized (27 to the intervention and 29 to the control, 55 practices participated) with 818 intervention and 677 controls completing the primary outcome measure. The intervention significantly increased RAS in high-risk participants compared with UCG (80.0% vs. 64.0%, respectively; OR = 3.14, 95% CI: 1.25-7.96) but not in average-risk (44.9% vs. 49.5%, respectively; OR = 0.97, 95% CI: 0.99-1.12) or moderate-risk individuals (67.9% vs. 81.1%, respectively; OR = 0.40, 95% CI: 0.12-1.33). Faecal occult blood testing uptake over 12 months was increased compared with the UCG (24.9% vs. 15.1%; adjusted OR = 1.66, 95% CI: 1.24-2.22), and there was a non-significant increase in colonoscopies during the same period (16.6% vs. 12.2%; adjusted OR = 1.42, 95% CI: 0.97-2.08). CONCLUSION: An online CRC risk calculator with risk-based screening recommendations increased RAS in high-risk participants and improved screening uptake overall within a 12-month follow-up period. Such tools may be useful for facilitating the uptake of risk-based screening guidelines.
RESUMEN
INTRODUCTION: Online drug markets operating on the 'darknet' ('cryptomarkets') facilitate the trade of illicit substances at an international level. The present study assessed the longitudinal impact on cryptomarket trading of two major disruptions: a large international law enforcement operation, 'Operation Onymous'; and the closure of the largest cryptomarket, Evolution. METHODS: Almost 1150 weekly snapshots of a total of 39 cryptomarkets were collected between October 2013 and November 2015. Data were collapsed by month and the number of unique vendor aliases operating across markets was assessed using interrupted time series regression. RESULTS: Following both Operation Onymous and the closure of Evolution, significant drops of 627 (p=0.014) and 910 vendors (p<0.001) were observed, respectively. However, neither disruption significantly affected the rate at which vendor numbers increased overall. CONCLUSIONS: Operation Onymous and the closure of Evolution were associated with considerable, though temporary, reductions in the number of vendors operating across cryptomarkets. Vendor numbers, however, recovered at a constant rate. While these disruptions likely impacted cryptomarket trading at the time, these markets appear resilient to disruption long-term.

BACKGROUND: To date monitoring of cryptomarkets operating on the dark net has largely focused on market size and substance availability. Less is known of country specific differences in these indicators and how they may corroborate population prevalence estimates for substance use in different countries. METHODS: All substance listings from the cryptomarket Agora were recorded over seven time points throughout February and March 2015. Agora was chosen due to its size as the second largest cryptomarket operating and the level of detail of information provided in individual substance listings. Data were collated and the number of unique sellers selling each substance by country of origin was analysed. RESULTS: An average of 14,456.7 substance listings were identified across sampled days from 868.7 unique sellers. The top five countries by number of listings were the USA, United Kingdom, Australia, China and the Netherlands, collectively accounting for 61.8% of all identified listings and 68% of all unique sellers. Australia was over represented in terms of sellers per capita, while China was over represented in new psychoactive substance (NPS) listings. When examined by number of listings per seller, the Netherlands and China stood out as particularly large, likely due to these countries' role in the local production of various illicit and new psychoactive substances. CONCLUSIONS: Numbers of sellers by country of origin appear to be influenced by several factors. Australia's overrepresentation in sellers per capita may indicate its relative geographical isolation and the potential for profit margins from selling online, while China's overrepresentation in NPS listings may reflect domestic production of these substances. Continued monitoring will provide enhanced understanding of the increasingly complex and globalised nature of illicit drug markets.

BACKGROUND: The past five years has seen a proliferation in marketplaces operating on the 'dark net' selling licit and illicit substances. While monitoring systems have investigated the specific substances for sale on these marketplaces, less is known about consumer motivations for accessing these marketplaces and factors associated with their use. METHODS: An Australian national sample (n=800) recruited on the basis of regular psychostimulant use was recruited and asked about purchasing substances from dark net marketplaces and the reasons for doing so. Respondents who had purchased any drug from a dark net marketplace in the preceding year were compared to those who had not in terms of demographic information and factors including drug use, criminal activity, and sexual and mental health. RESULTS: Nine percent (n=68) of the sample had purchased from dark net markets in the past year. MDMA, LSD and cannabis were the three most commonly purchased substances, and the main benefits cited for purchasing online were the better quality and lower cost of drugs available. Controlling for other factors, participants who purchased from dark net marketplaces in the past year tended to be younger, more likely to be involved in recent property crime and to have used more classes of drugs in the preceding six months, specifically psychedelics and 'new psychoactive drugs'. CONCLUSIONS: Though a small minority of participants reported having purchased drugs online in the preceding six months, these appeared to be a more 'entrenched' group of consumers, with more diverse substance use and rates of criminal activity. For consumers in the current sample reporting recent dark net usage, country borders are now less of a significant barrier to purchase and there is a wider range of substances available than ever before.

BACKGROUND: Smoking cessation research output should move beyond descriptive research of the health problem to testing interventions that can provide causal data and effective evidence-based solutions. This review examined the number and type of published smoking cessation studies conducted in low-socioeconomic status (low-SES) and disadvantaged population groups. METHODS: A systematic database search was conducted for two time periods: 2000-2004 (TP1) and 2008-2012 (TP2). Publications that examined smoking cessation in a low-SES or disadvantaged population were coded by: population of interest; study type (reviews, non-data based publications, data-based publications (descriptive, measurement and intervention research)); and country. Intervention studies were coded in accordance with the Cochrane Effective Practice and Organisation of Care data collection checklist and use of biochemical verification of self-reported abstinence was assessed. RESULTS: 278 citations were included. Research output (i.e., all study types) had increased from TP1 27% to TP2 73% (χ²=73.13, p<0.001), however, the proportion of data-based research had not significantly increased from TP1 and TP2: descriptive (TP1=23% vs. TP2=33%) or intervention (TP1=77% vs. TP2=67%). The proportion of intervention studies adopting biochemical verification of self-reported abstinence had significantly decreased from TP1 to TP2 with an increased reliance on self-reported abstinence (TP1=12% vs. TP2=36%). CONCLUSIONS: The current research output is not ideal or optimal to decrease smoking rates. Research institutions, scholars and funding organisations should take heed to review findings when developing future research and policy.

The current study, in parallel experiments, evaluated the impact of chronic psychological stress on physiological and behavioural measures, and on the activation status of microglia in 15 stress-responsive brain regions. Rats were subjected, for 14 days, to two 30 min sessions of restraint per day, applied at random times each day. In one experiment the effects of stress on sucrose preference, weight gain, core body temperature, and struggling behaviour during restraint, were determined. In the second experiment we used immunohistochemistry to investigate stress-induced changes in ionized calcium-binding adaptor molecule-1 (Iba1), a marker constitutively expressed by microglia, and major histocompatibility complex-II (MHC-II), a marker often expressed on activated microglia, in a total of 15 stress-responsive nuclei. We also investigated cellular proliferation in these regions using Ki67 immunolabelling, to check for the possibility of microglial proliferation. Collectively, the results we obtained showed that chronic stress induced a significant increase in anhedonia, a decrease in weight gain across the entire observation period, a significant elevation in core body temperature during restraint, and a progressive decrease in struggling behaviour within and over sessions. With regard to microglial activation, chronic stress induced a significant increase in the density of Iba1 immunolabelling (nine of 15 regions) and the number of Iba1-positive cells (eight of 15 regions). Within the regions that exhibited an increased number of Iba1-positive cells after chronic stress, we found no evidence of a between group difference in the number of MHC-II or Ki67 positive cells. In summary, these results clearly demonstrate that chronic stress selectively increases the number of microglia in certain stress-sensitive brain regions, and also causes a marked transition of microglia from a ramified-resting state to a non-resting state. These findings are consistent with the view that microglial activation could play an important role in controlling and/or adapting to stress.

The double-hit hypothesis posits that an early life genetic or environmental insult sets up a neural predisposition to psychopathology, which may emerge in the presence of a subsequent insult, or 'second hit' in later life. The current study assessed the effect of neonatal lipopolysaccharide (LPS) exposure on anxiety-like behaviours in the adult Wistar rat. Rats were administered either LPS (Salmonella enterica, serotype enteritidis, 0.05 mg/kg, i.p.) or saline (equivolume) on days 3 and 5 of life (birth=day 1). In adulthood (85 days), subjects were allocated to either "stress" or "no stress" treatment groups. For the "stress" group, subjects were exposed to a three-day stress protocol consisting of a 30 min period of restraint and isolation. The "no stress" group was left unperturbed but were handled during this period to control for handling effects between adult "stress" and "no stress" conditions. All animals then underwent behavioural testing using standardised tests of anxiety-like behaviour, including either the Hide Box/Open Field, Elevated Plus Maze (EPM) or Acoustic Startle Response (ASR). Time and event measures for restraint and isolation, the Hide Box/Open Field and EPM were recorded using automated tracking software. Startle amplitude and habituation across time was measured in the ASR test. Prior to and following behavioural test sessions, peripheral blood was collected to assess serum corticosterone and ACTH levels. Data analysis indicated that LPS-treated animals exposed to stress in adulthood exhibited increased anxiety-like behaviour across all behavioural tests compared to controls. Sexually dimorphic effects were observed with males exhibiting increased anxiety-related behaviours compared to females (p<.05). Neonatal LPS exposure induced a significant increase in corticosterone compared to controls (p<.05), whereas corticosterone responses to stress in adulthood were associated with a significantly blunted HPA axis response (p<.05). No differences in ACTH were observed. These results lend support to the double-hit hypothesis of anxiety-related behaviour, demonstrating that neonatal immune activation produces an enhanced propensity toward anxiety-related behaviour following stress in adulthood, and that this susceptibility is associated with alterations to HPA axis ontogeny.

The aim of the current study was to generate socially conditioned fear in two different strains of rat (Wistar, W and Sprague Dawley, SD) using social conflict, in order to investigate whether the magnitude of the conditioned fear responses in each strain was related to behaviour exhibited prior to or during fear induction (i.e. social conflict). On day one of the study, all intruders were assessed for exploratory activity in a novel environment. Twenty four hours following the novel environment test the locomotor activity of the intruders was assessed, while they underwent a single familiarisation exposure to the arena in which the conflict was subsequently to occur in. Twenty-four hours following familiarisation, intruders underwent either a 10 min social conflict or sham conflict session. One day later we examined the response of the intruders when they were returned to the vacant resident's cage. Upon return to the conflict context, we examined the intruder's ultrasonic distress vocalisations and the extent to which locomotor activity was inhibited. We found that W rats displayed significantly more immobility (i.e. conditioned fear) upon return to context than did SD rats (p < 0.05). Importantly, we observed that the differences in the two strains behaviour upon return to context appeared to be related to their quite different patterns of coping behaviour. The results of the current study indicate that preclinical between-strain comparisons potentially have much to offer in regard to understanding the basis of resilience to social stress.
