RESUMO

The term neurodiversity was coined in the 1990s to describe a diversity in thinking, learning, and processing the world around us, and is associated with strengths as well as challenges. Rates of diagnosis of neurodivergent conditions are rising rapidly amongst patients and healthcare professionals, largely due to a recent surge in awareness and understanding of neurodiverse conditions and more inclusive diagnostic criteria. Societal adaptation, however, has lagged, and likely explains some of the psychosocial comorbidities of neurodiversity, as individuals are forced to adapt their personality and how they display their emotions to fit societal norms. There remains a lack of awareness and understanding of neurodiversity amongst the healthcare professions. There is also very limited published literature on the challenges and strengths of this group in the clinical environment. Here, we use a case study, focusing on attention deficit hyperactivity disorder to explore the relationship between neurodiversity and work from the perspective of a neurodiverse health care professional. We challenge the notion that neurodiversity itself is a disability, but more likely a result of lack of societal awareness and adaption. We suggest accommodations and training in the clinical environment to raise awareness and support neurodiverse healthcare professionals in order that they flourish rather than struggle in the workplace.

RESUMO

BACKGROUND: The COVID-19 pandemic has affected most industries, including health education. In this study, we surveyed students studying healthcare-related courses at our university on how their lifestyles and behaviours, mental health and education had been affected by the pandemic. METHODS: Mixed methods cross-sectional study. RESULTS: Two hundred thirty-three students responded to the questionnaire. Lifestyle and behaviours: 51.5% of the participants changed their diet (n=120); 45.5% (n=106) exercised less; 66.5% (n=155) experienced a change in sleep; 51.1% (n=119) reported a change in appetite. Mental health: 84.2% (n=196) reported worrying too much about different things; 61.9% (n=144) could not stop or control worrying; 71.2% experienced trouble relaxing on several days or more (n=166). At least sometimes, 72.1% (n=168) felt unable to cope with things they had to do; 8.5% (n=20) never, or almost never, felt confident about handling personal problems. Education: 65.7% (n=153) struggled to complete learning outcomes with online delivery; 82% (n=191) worried about practical skills being affected; 60.5% (n=141) worried about the impact of COVID-19 on their future career. Almost half (48.9%, n=114) believed that online teaching should be part of the standard curriculum. CONCLUSION: In general, there was a negative impact on behaviours, lifestyle and mental health and virtual education was perceived as necessary in making up for the loss of face to face experiences. Students' mental health and educational needs have been affected by the current pandemic and healthcare educational facilities must respond to these needs to ensure students continue to receive the support they need.

RESUMO

OBJECTIVES: In response COVID-19, re-establishing safe elective services was prioritised in the UK. We assess the impact on face-to-face hospital attendance, cost and efficiency of implementing a virtual sleep clinic (intervention 1) to screen for children requiring level 3 ambulatory sleep studies using newly implemented ENT-UK guidelines for obstructive sleep apnoea (OSA) investigation (intervention 2). OBJECTIVES: (1) compare the proportion of children attending sleep clinic undertaking a sleep study before and after implementation of these interventions; (2) compare clinic cancellations and first-time success rates of sleep studies before and after intervention. DESIGN: Retrospective analysis. SETTING: District general hospital paediatric sleep clinic. PARTICIPANTS: Children aged 3 months to 16 years referred to sleep clinic by ENT for investigation of OSA over 3 months immediately following interventions (1 June 2020 - 1 September 2020) to the same period in the previous year (1 June 2019 - 1 September 2019). MAIN OUTCOME MEASURES: Number of children attending sleep clinic, date of birth/age of children attending sleep clinic, number of children undergoing sleep study, diagnostic outcomes, number of appointment cancellations, number of first-time sleep study failures. RESULTS: Post intervention, there was a significant reduction in the proportion of children undertaking ambulatory sleep studies, and nonsignificant reductions in appointment cancellations and in first-time sleep study failures. CONCLUSIONS: The introduction of the virtual sleep clinic meant that only those children requiring a sleep study attended a face-to-face appointment, which led to reduced face-to-face attendance. There were also unintended cost-effectiveness and efficiency benefits, with potential longer-term learning implications for the wider sleep community and other diagnostic services.

RESUMO

Austropurcellia, a genus of dispersal-limited arachnids endemic to isolated patches of coastal rainforest in Queensland, Australia, has a remarkable biogeographic history. The genus is a member of the family Pettalidae, which has a classical temperate Gondwanan distribution; previous work has suggested that Austropurcellia is an ancient lineage, with an origin that predates Gondwanan rifting. Subsequently, this lineage has persisted through major climatic fluctuations, such as major aridification during the Miocene and contraction and fragmentation of forest habitats during the Last Glacial Maximum (LGM). In order to understand Austropurcellia's evolutionary and biogeographic history, we generated DNA sequences from both mitochondrial and nuclear loci and combined this information with previously published datasets for the globally-distributed suborder Cyphophthalmi (i.e., all mite harvestmen). We generated phylogenetic trees using maximum likelihood and Bayesian approaches to date divergences using a relaxed molecular clock. According to our estimates, the family Pettalidae diversified in the late Jurassic, in accordance with Gondwanan vicariance. Within Pettalidae, Austropurcellia split from its sister group in the early Cretaceous and began to diversify some 15 Ma later. Therefore, its presence in Australia predates continental rifting-making it one of very few hypothesized examples of Gondwanan vicariance that have withstood rigorous testing. We found a steady rate of diversification within the genus, with no evidence for a shift in rate associated with Miocene aridification. Ages of splits between species predate the Pleistocene, consistent with a "museum" model in which forest refugia acted to preserve existing lineages rather than drive speciation within the group.

RESUMO

The scorpion family Bothriuridae occupies a subset of landmasses formerly constituting East and West temperate Gondwana, but its relationship to other scorpion families is in question. Whereas morphological data have strongly supported a sister group relationship of Bothriuridae and the superfamily Scorpionoidea, a recent phylogenomic analysis recovered a basal placement of bothriurids within Iurida, albeit sampling only a single exemplar. Here we reexamined the phylogenetic placement of the family Bothriuridae, sampling six bothriurid exemplars representing both East and West Gondwana, using transcriptomic data. Our results demonstrate that the sister group relationship of Bothriuridae to the clade ("Chactoidea" + Scorpionoidea) is supported by the inclusion of additional bothriurid taxa, and that this placement is insensitive to matrix completeness or partitioning by evolutionary rate. We also estimated divergence times within the order Scorpiones using multiple fossil calibrations, to infer whether the family Bothriuridae is sufficiently old to be characterized as a true Gondwanan lineage. We show that scorpions underwent ancient diversification between the Devonian and early Carboniferous. The age interval of the bothriurids sampled (a derived group that excludes exemplars from South Africa) spans the timing of breakup of temperate Gondwana.

RESUMO

RATIONALE: Improving the early detection and chemoprevention of lung cancer are key to improving outcomes. The pathobiology of early squamous lung cancer is poorly understood. We have shown that amplification of sex-determining region Y-box 2 (SOX2) is an early and consistent event in the pathogenesis of this disease, but its functional oncogenic potential remains uncertain. We tested the impact of deregulated SOX2 expression in a novel organotypic system that recreates the molecular and microenvironmental context in which squamous carcinogenesis occurs. OBJECTIVES: (1) To develop an in vitro model of bronchial dysplasia that recapitulates key molecular and phenotypic characteristics of the human disease; (2) to test the hypothesis that SOX2 deregulation is a key early event in the pathogenesis of bronchial dysplasia; and (3) to use the model for studies on pathogenesis and chemoprevention. METHODS: We engineered the inducible activation of oncogenes in immortalized bronchial epithelial cells. We used three-dimensional tissue culture to build an organotypic model of bronchial dysplasia. MEASUREMENTS AND MAIN RESULTS: We recapitulated human bronchial dysplasia in vitro. SOX2 deregulation drives dysplasia, and loss of tumor promoter 53 is a cooperating genetic event that potentiates the dysplastic phenotype. Deregulated SOX2 alters critical genes implicated in hallmarks of cancer progression. Targeted inhibition of AKT prevents the initiation of the dysplastic phenotype. CONCLUSIONS: In the appropriate genetic and microenvironmental context, acute deregulation of SOX2 drives bronchial dysplasia. This confirms its oncogenic potential in human cells and affords novel insights into the impact of SOX2 deregulation. This model can be used to test therapeutic agents aimed at chemoprevention.

RESUMO

OBJECTIVE: Functional electrical stimulation is used to improve walking speed and reduces falls in people with upper motor neurone foot-drop. Following anecdotal observations of changes in bladder symptoms, an observational study was performed to explore this association further. DESIGN: A total of 47 consecutive patients attending for setup with functional electrical stimulation during a six-month period were asked to complete a questionnaire assessing bladder symptoms (ICIQ-OAB (International Consultation on Incontinence Questionnaire Overactive Bladder)) at baseline and three months during routine appointments. SUBJECTS: In all, 35 (75%) had multiple sclerosis and the other 12 subjects had a total of 9 diagnoses including 3 with stroke. Other conditions included cerebral palsy, motor neurone disease, hereditary spastic paraparesis, meningioma and spinocerebellar ataxias. RESULTS: Improvement in overactive bladder symptoms was not significant in the whole cohort, however, was significant in patients with multiple sclerosis ( n = 35; mean change in ICIQ-OAB score 1.0, P = 0.043). Specifically, significant improvements were seen in urgency and urge incontinence in multiple sclerosis patients. There was a significant negative correlation of moderate strength within the multiple sclerosis cohort between baseline walking speed and subsequent change in ICIQ-OAB score (correlation coefficient of r = -0.40, P = 0.046). Thus, greater changes in bladder symptoms were seen with lower baseline walking speeds. CONCLUSION: The results of this exploratory study suggest that functional electrical stimulation use does improve overactive bladder symptoms in people with multiple sclerosis. Further exploration is needed to study this association and explore whether the mechanism is similar to that of percutaneous tibial nerve stimulation, a recognized treatment for the overactive bladder.

RESUMO

Contralateral prophylactic mastectomy (CPM) and bilateral prophylactic mastectomy (BPM) markedly decrease the possibility of new breast cancer (BC) ipsilateral to the prophylactic mastectomy (PM). Given its relative infrequency, little is known about the clinical characteristics, presentation, and management of BC after PM. Between 1960 and 1993, 1065 women underwent BPM and 1643 women with unilateral BC treated with therapeutic mastectomy underwent CPM at our institution. Medical records were reviewed, and study-specific questionnaires were sent to all women. BC after PM included locoregional invasive BC or ductal carcinoma in situ ipsilateral to the PM. BC developed ipsilateral to the PM in 25 patients (13 after BPM; 12 after therapeutic mastectomy and CPM). Median follow-up after PM was 22 years (range 3-34 years). Presentations included clinically isolated local disease in 17 patients (68%); disease limited to the axilla without evidence of local primary disease in 4 (16%); synchronous local and axillary disease in 1 (4%); and synchronous local disease and distant metastases in 3 (12%). The 17 patients presenting with isolated local disease were most commonly managed with completion or redo mastectomy (65%) or local excision (29 %), followed by consideration of adjuvant therapy. The 5-year disease-free survival estimate was 69% (95% CI 52-94%) for the 22 patients who had isolated locoregional BC after PM and were treated with curative intent. Although rare, BC after PM can occur. The most common presentation, disease localized to the mastectomy site, can be managed with resection and consideration of adjuvant therapy.

RESUMO

BACKGROUND: Contralateral prophylactic mastectomy (CPM) is increasingly chosen by breast cancer patients and may be related to increased use of immediate reconstruction. This study examines long-term patient satisfaction with CPM and reconstruction in a historical cohort. METHODS: 621 unilateral breast cancer patients with a family history of breast cancer who underwent CPM between 1960 and 1993 were surveyed regarding quality of life (QOL) and satisfaction with CPM at two time points (approximately 10 and 20 years after CPM). RESULTS: 583 women responded to the first follow-up questionnaire (median 10.7 years; mean 11.9 years) after CPM. There were 403 (69 %) patients who underwent reconstruction and 180 (31 %) patients who did not. Women electing reconstruction were younger [mean age 47 versus (vs.) 53 years; p = 0.01] and more likely to be married (85 vs. 78 %; p = 0.048). Most women reported satisfaction with CPM (83 %), and they would choose CPM again (84 %) and make the same choice regarding reconstruction (73 %). However, reconstruction patients demonstrated significantly lower satisfaction (p = 0.0001) and were less likely to choose CPM again (p < 0.0001). Within the reconstruction group, 39 % needed 1 + unplanned reoperation, which was strongly associated with lower satisfaction (p = 0.0001), lower likelihood of choosing CPM again (p = 0.006), and lower likelihood of choosing reconstruction again (p < 0.0001). There were 269 women who responded to the second questionnaire (median 18.4 years; mean 20.2 years after CPM). Satisfaction with CPM remained high, with 92 % of the women stating they would choose CPM again. CONCLUSIONS: Most women report stable long-term satisfaction with CPM. Women who had reconstruction and required reoperations in this historical cohort reported lower satisfaction.

RESUMO

Klippel-Trenaunay Syndrome (KTS) is a rare congenital vascular disorder characterized by extensive capillary and venous malformations that pose unique challenges during pregnancy. This case report discusses the successful management of a 34-year-old pregnant woman with KTS who had two caesarean sections, resulting in the birth of two healthy babies. Despite the lack of evidence-based guidelines for obstetrical management in KTS, a multidisciplinary team collaborated to devise a high-risk thrombosis management plan, involving the use of compression stocking and low molecular weight heparin prophylaxis. The patient's elevated risk of thrombosis, exacerbated during pregnancy, informed the decision of caesarean sections, aligning with finding that in most KTS pregnancies, this method of delivery based on obstetric indications and arteriovenous malformations is chosen. This case highlights the importance of systematic and patient-centered care, advocating for comprehensive obstetric management guidelines to address the unique challenges posed by KTS during pregnancy. Further research is warranted to enhance our understanding and refine guidelines for individuals with vascular abnormalities linked to KTS.

RESUMO

Medical Respite Programs (MRPs) characterize a care model that has been developed to address the health care and social needs of persons experiencing homelessness by providing post-acute hospital care in a safe environment. Although this model has been shown to reduce hospitalizations, improve health outcomes and increase access to health services, prior studies of MRP programs and outcomes have been limited to individual sites and may not generalize to the population of individuals receiving MRP care. This study protocol describes a mixed method design to collect organizational, provider, and patient-level data from a sample of MRPs.

RESUMO

Background: In the UK approximately half of women requiring perinatal mental health (PNMH) care do not receive treatment despite having routine contact with midwives (MWs) and health visitors (HVs). Limited research has been undertaken regarding MWs'/HVs' decision-making around referring women for secondary PNMH care. In particular, the impact that the level of local secondary PNMH services may have on MWs'/HVs' referral decisions is unexplored. Aim: To understand MWs'/HVs' decision-making in relation to referring women with identified PNMH problems, to identify barriers and facilitators to effective and timely referrals including any impact of the local secondary PNMH service provision. Methods: Participants were recruited from four National Health Service (NHS) Trusts in England, located across two geographical areas, that provided different types of PNMH services. One area had PNMH services that met National Institute for Health and Care Excellence (NICE) guidelines; the other area had no secondary PNMH services. A sequential mixed methods design was used: In-depth semi-structured interviews with practising MWs/HVs (n = 24) to explore their approach to PNMH referral decision-making, analysed using thematic analysis; Questionnaire offered to all practising MWs/HVs in the two geographical areas to measure factors that may impact on PNMH referral decision-making allowing for statistical comparisons to be made between the professional groups/geographical areas. Findings: Three themes were identified from the interviews that impacted on MWs'/HVs' PNMH referral decision-making: identifying need; education, skills and experience; and referral pathways.Questionnaire response rate 13.1% (n = 99). The most reported facilitators to referral decision-making were a trusted relationship between MWs/HVs and women and routine enquiry about women's mental health; the most reported barriers were stigma associated with mental ill-health and women's perceived fear of child removal. Conclusion: Fundamental to MWs'/HVs' decision-making was their perceived relationship between themselves and women. Although PNMH service provision is important for women to ensure they receive appropriate PNMH care, service provision appeared less important to MWs'/HVs' referral decision-making than how maternity/health visiting services were delivered. Further important factors to MWs/HVs were to the ability to provide continuity of carer with women allowing MWs/HVs to identify women who would benefit from referral for secondary PNMH care.

RESUMO

PURPOSE: This study aims to evaluate the long-term consistency of satisfaction with contralateral prophylactic mastectomy (CPM) and adverse psychosocial effects as well as to explore the effect of informed decision-making, personality traits, and quality of life (QOL) on satisfaction. METHODS: A previously established cohort of women with unilateral breast cancer who had undergone CPM between 1960 and 1993 were surveyed using study-specific and standardized questionnaires at two follow-up time points. The first survey was a mean of 10.7 years and the second survey a mean of 20.2 years after CPM. RESULTS: 487 of the 583 women who responded to the first study were alive and resurveyed. Data from both surveys were available for 269 women. With longer follow-up, there was a small increase in the percentage of women satisfied (90%) and those who would choose CPM again (92%) (4% and 2% increase from first survey, respectively). Most adversely affected were body appearance (31%), feelings of femininity (24%), and sexual relationships (23%). Ninety-three percent of women felt they had made an informed decision. Perception of making an informed choice and current QOL were moderately associated with satisfaction with CPM (r = 0.37 and 0.37, respectively) while associations with trait anxiety and optimism were weak (r = 0.27 and 0.21, respectively). CONCLUSIONS: Long-term satisfaction and adverse effects remained remarkably stable. It is important that women fully understand the benefits and adverse effects associated with CPM.

RESUMO

BACKGROUND: Patient participation in handover is one aspect of patient-centred care, where patients are considered partners in care. Understanding the patient perspective provides a foundation for nurses to tailor their bedside handovers to reflect patients' thoughts and beliefs and encourage their active involvement in decision-making. AIM: This study examined patients' perspectives of participation in shift-to-shift bedside nursing handover. METHODS: A descriptive case study was conducted with 10 patients in one Queensland hospital who had experienced bedside handover during their hospitalisation in 2009. Participants were asked their views about bedside handover including its benefits and limitations, their existing and potential role in handover, the role of family members, and issues related to confidentiality. Data were analysed using thematic content analysis. FINDINGS: Four themes emerged from the analysis. First, patients appreciated being acknowledged as partners in their care. Second, they viewed bedside handover as an opportunity to amend any inaccuracies in the information being communicated. Third, some preferred passive engagement rather than being fully engaged in the handover. Fourth, most patients appreciated the inclusive approach of handover as nurse-patient interaction. CONCLUSIONS: Bedside handover provides an opportunity for patients to be involved as active participants in their care. They value having access to information on an ongoing basis, and although not all choose the same level of interaction, they see their role as important in maintaining accuracy, which promotes safe, high quality care.

RESUMO

PURPOSE: Undergraduate clinical placements have the potential for significant improvement. Previous research has shown the growing value of clinical teaching fellows (CTFs) within medical education. Changing traditional placements to a model whereby CTFs have defined roles and lead the majority of teaching can positively reinvent undergraduate clinical teaching. We wanted to see how a structured teaching programme delivered by CTFs could affect student experience and personal development within a large associate teaching hospital. We consider how such a model could be implemented and explore the opportunities for CTFs to develop in personal and professional capacities. METHODS: A mixed methods study was organised to assess student experience of a CTF-led placement. A novel structured teaching programme was delivered by 14 CTFs, who provided or were involved with the majority of teaching for all medical students. Thematic analysis was conducted on focus groups with 48 final year medical students from Queen Mary University of London following completion of their clinical placements. The same students were asked to complete an anonymous survey from which results were analysed using modified 5-point Likert scales. RESULTS: Eight themes were identified from the focus groups. Students appreciated the increased individualisation, relevance and variety of teaching and the ability to record progress. Other perceived effects were higher teacher to student ratios, more learning opportunities and increased familiarity and reliability with CTFs. Of the students surveyed, 96% felt their overall placement experience was very good in comparison to previous placements elsewhere. Survey results supported focus group themes and demonstrated perceived growth in students' personal development. CONCLUSION: Placement models where CTFs lead most teaching can improve medical undergraduate experience and training. A move towards CTF-delivered teaching can be of financial benefit to hospital trusts whilst allowing time for junior doctors to explore different clinical specialities and hone their teaching skills.

RESUMO

CTP:phosphocholine cytidylyltransferase (CCT) is the key regulatory enzyme in the synthesis of phosphatidylcholine, the most abundant phospholipid in eukaryotic cell membranes. The CCT-catalyzed transfer of a cytidylyl group from CTP to phosphocholine to form CDP-choline is regulated by a membrane lipid-dependent mechanism imparted by its C-terminal membrane binding domain. We present the first analysis of a crystal structure of a eukaryotic CCT. A deletion construct of rat CCTalpha spanning residues 1-236 (CCT236) lacks the regulatory domain and as a result displays constitutive activity. The 2.2-A structure reveals a CCT236 homodimer in complex with the reaction product, CDP-choline. Each chain is composed of a complete catalytic domain with an intimately associated N-terminal extension, which together with the catalytic domain contributes to the dimer interface. Although the CCT236 structure reveals elements involved in binding cytidine that are conserved with other members of the cytidylyltransferase superfamily, it also features nonconserved active site residues, His-168 and Tyr-173, that make key interactions with the beta-phosphate of CDP-choline. Mutagenesis and kinetic analyses confirmed their role in phosphocholine binding and catalysis. These results demonstrate structural and mechanistic differences in a broadly conserved protein fold across the cytidylyltransferase family. Comparison of the CCT236 structure with those of other nucleotidyltransferases provides evidence for substrate-induced active site loop movements and a disorder-to-order transition of a loop element in the catalytic mechanism.

RESUMO

BACKGROUND: The aim of this study was to investigate whether contralateral prophylactic mastectomy (CPM) in addition to therapeutic mastectomy (TM) is associated with a survival advantage in high-risk women with breast cancer. METHODS: A total of 385 women with stage I or II breast cancer and a family history of breast cancer who underwent TM and CPM between 1971 and 1993 were evaluated and compared to 385 patients matched on age at diagnosis, tumor stage, nodal status, and year of diagnosis who underwent TM-only. Contralateral breast cancer (CBC) events and survival outcomes were compared. RESULTS: At a median follow-up of 17.3 years, 2 CBCs (0.5%) developed in the CPM cohort and 31 (8.1%) in the TM-only cohort, representing a 95% decreased risk of CBC (hazard ratio [HR] = 0.05, 95% confidence interval [95% CI] 0.01-0.22, P < 0.0001). One hundred twenty-eight women in the CPM group and 162 women in the TM-only group have died, resulting in 10-year overall survival estimates of 83 and 74%, respectively (HR 0.68, 95% CI 0.54-0.86, P = 0.001). This difference in overall survival persisted in multivariate analysis (HR 0.77, P = 0.03). Disease-free survival (DFS) was better in the CPM cohort than the TM-only group (HR 0.66, 95% CI 0.53-0.82, P = 0.0002) and remained significant in multivariate analysis (HR 0.67, P = 0.0005). CONCLUSIONS: In this retrospective cohort study, CPM was associated with decreased CBC event and improved overall survival and disease free survival.

RESUMO

AIM: This paper is a report of the effects of implementing 13 Transforming Care At the Bedside improvement strategies on medication errors, patient falls and pressure ulcers. BACKGROUND: A number of international reports and research studies have led to a focus on safety and quality in health care. Transforming Care At the Bedside involves nursing managers and front-line staff together contributing to practice improvement. METHOD: An observational, time series study in two medical units in one Australian hospital was conducted. Statistical process control analysis was used to identify changes in the outcomes. Routinely collected, anonymous clinical incident reports were used to calculate the proportion of reported clinical incidents that were reported to result in patient harm in the 15 months prior to and 18 months after Transforming Care At the Bedside strategies were implemented, between February, 2005 and December, 2007. RESULTS: The proportion of reported medication errors, falls and pressure ulcers that resulted in harm as reported in clinical incident reports were reduced from 46.3% to 17.1%, 97.0% to 51.0% and 91.3% to 46.6% respectively, representing an absolute reduction by about one half. Consistent, sustained improvement in the first two was demonstrated, but analysis showed wide variation in the third--pressure ulcers--which meant that the differences in this outcome may have occurred by chance. CONCLUSION: A rapid change management cycle such as Transforming Care At the Bedside can be a useful process when implementing numerous clinical changes in short succession.

RESUMO

With the aging population, the tide of chronic disease is rising with attendant increases in health service need. Integrated care and patient-centred approaches, which established partnerships between a regional Hospital and health service (HHS), the local primary health network and local general practitioners (GPs), were identified as exemplars of an approach needed to support growing community health needs. This paper summarises the findings from a process evaluation of four GP-specialist care integration programs with the aim of identifying recommendations for embedding integrated GP-specialist care into routine practice within the HHS. The process evaluation of the integration programs drew on input from a multidisciplinary expert advisory group and data collected through face-to-face semi-structured interviews with key stakeholders, as well as surveys of participating GPs and patients. Overarching findings were identified and grouped under six themes: interdisciplinary teamwork; communication and information exchange; the use of shared care guidelines or pathways; training and education; access and accessibility; and funding. Within each theme, key challenges and enablers emerged. The findings of this study highlight benefits and challenges associated with the establishment of integrated care between primary and secondary care providers, leading to the development of key recommendations for routine integration.
