    Researchers working in the field, the places where research-relevant activity happens, are essential to recruitment and data collection in randomised controlled trials (RCTs). This study aimed to understand the nature of this often invisible work. Data were generated through an RCT of a pharmacist-led medication management service for older people in care homes. The study was conducted over three years and employed seven Research Associates (RA) working in Scotland, Northern Ireland, and England. Weekly research team meetings and Programme Management Group meetings naturally generated 129 sets of minutes. This documentary data was supplemented with two end-of-study RA debriefing meetings. Data were coded to sort the work being done in the field, then deductively explored through the lens of Normalization Process Theory to enable a greater understanding of the depth, breadth and complexity of work carried out by these trial delivery RAs. Results indicate RAs helped stakeholders and participants make sense of the research, they built relationships with participants to support retention, operationalised complex data collection procedures and reflected on their own work contexts to reach agreement on changes to trial procedures. The debrief discussions enabled RAs to explore and reflect on experiences from the field which had affected their day-to-day work. The learning from the challenges faced in facilitating care home research may be useful to inform future research team preparation for complex interventions. Scrutinising these data sources through the lens of NPT enabled us to identify RAs as linchpins in the successful conduct of a complex RCT study

    An Uncertain Dominion: Irish Psychiatry, Methadone, and the Treatment of Opiate Abuse

    Get PDF
    This paper investigates some productive ambiguities around the medical administration of methadone in the Republic of Ireland. The tensions surrounding methadone maintenance therapy (MMT) are outlined, as well as the sociohistorical context in which a serious heroin addiction problem in Ireland developed. Irish psychiatry intervened in this situation, during a time of institutional change, debates concerning the nature of addiction, moral panics concerning heroin addiction in Irish society and the recent boom in the Irish economy, known popularly as the Celtic Tiger. A particular history of this sort illuminates how technologies like MMT become cosmopolitan, settling into, while changing, local contexts

    An examination of polygenic score risk prediction in individuals with first-episode psychosis

    Background Polygenic risk scores (PRSs) have successfully summarized genome-wide effects of genetic variants in schizophrenia with significant predictive power. In a clinical sample of first-episode psychosis (FEP) patients, we estimated the ability of PRSs to discriminate case-control status and to predict the development of schizophrenia as opposed to other psychoses. Methods The sample (445 case and 265 control subjects) was genotyped on the Illumina HumanCore Exome BeadChip with an additional 828 control subjects of African ancestry genotyped on the Illumina Multi-Ethnic Genotyping Array. To calculate PRSs, we used the results from the latest Psychiatric Genomics Consortium schizophrenia meta-analysis. We examined the association of PRSs with case-control status and with schizophrenia versus other psychoses in European and African ancestry FEP patients and in a second sample of 248 case subjects with chronic psychosis. Results PRS had good discriminative ability of case-control status in FEP European ancestry individuals (9.4% of the variance explained, p < 10−6), but lower in individuals of African ancestry (R2 = 1.1%, p = .004). Furthermore, PRS distinguished European ancestry case subjects who went on to acquire a schizophrenia diagnosis from those who developed other psychotic disorders (R2 = 9.2%, p = .002). Conclusions PRS was a powerful predictor of case-control status in a European sample of patients with FEP, even though a large proportion did not have an established diagnosis of schizophrenia at the time of assessment. PRS was significantly different between those case subjects who developed schizophrenia from those who did not, although the discriminative accuracy may not yet be sufficient for clinical utility in FEP

    Priorities and strategies for improving disabled women's access to maternity services when they are affected by domestic abuse:a multi-method study using concept maps

    Get PDF
    BACKGROUND: Domestic abuse is a significant public health issue. It occurs more frequently among disabled women than those without a disability and evidence suggests that a great deal of domestic abuse begins or worsens during pregnancy. All women and their infants are entitled to equal access to high quality maternity care. However, research has shown that disabled women who experience domestic abuse face numerous barriers to accessing care. The aim of the study was to identify the priority areas for improving access to maternity services for this group of women; develop strategies for improved access and utilisation; and explore the feasibility of implementing the identified strategies. METHODS: This multi-method study was the third and final part of a larger study conducted in the UK between 2012 and 2014. The study used a modified concept mapping approach and was theoretically underpinned by Andersen’s model of healthcare use. Seven focus group interviews were conducted with a range of maternity care professionals (n = 45), incorporating quantitative and qualitative components. Participants ranked perceived barriers to women’s access and utilisation of maternity services in order of priority using a 5-point Likert scale. Quantitative data exploration used descriptive and non-parametric analyses. In the qualitative component of each focus group, participants discussed the barriers and identified potential improvement strategies (and feasibility of implementing these). Qualitative data were analysed inductively using a framework analysis approach. RESULTS: The three most highly ranked barriers to women’s access and utilisation of maternity services identified in the quantitative component were: 1) staff being unaware and not asking about domestic abuse and disability; 2) the impact of domestic abuse on women; 3) women’s fear of disclosure. The top two priority strategies were: providing information about domestic abuse to all women and promoting non-judgemental staff attitude. These were also considered very feasible. The qualitative analysis identified a range of psychosocial and environmental barriers experienced by this group of women in accessing maternity care. Congruent with the quantitative results, the main themes were lack of awareness and fear of disclosure. Key strategies were identified as demystifying disclosure and creating physical spaces to facilitate disclosure. CONCLUSIONS: The study supports findings of previous research regarding the barriers that women face in accessing and utilising maternity services, particularly regarding the issue of disclosure. But the study provides new evidence on the perceived importance and feasibility of strategies to address such barriers. This is an important step in ensuring practice-based acceptability and ease with which improvement strategies might be implemented in maternity care settings

    Development of a Core Outcome Set for effectiveness trials aimed at optimising prescribing in older adults in care homes

    Get PDF
    Background: Prescribing medicines for older adults in care homes is known to be sub-optimal. Whilst trials testing interventions to optimise prescribing in this setting have been published, heterogeneity in outcome reporting has hindered comparison of interventions, thus limiting evidence synthesis. The aim of this study was to develop a core outcome set (COS), a list of outcomes which should be measured and reported, as a minimum, for all effectiveness trials involving optimising prescribing in care homes. The COS was developed as part of the Care Homes Independent Pharmacist Prescribing Study (CHIPPS). Methods: A long-list of outcomes was identified through a review of published literature and stakeholder input. Outcomes were reviewed and refined prior to entering a two-round online Delphi exercise and then distributed via a web link to the CHIPPS Management Team, a multidisciplinary team including pharmacists, doctors and Patient Public Involvement representatives (amongst others), who comprised the Delphi panel. The Delphi panellists (n = 19) rated the importance of outcomes on a 9-point Likert scale from 1 (not important) to 9 (critically important). Consensus for an outcome being included in the COS was defined as ≥70% participants scoring 7–9 and <15% scoring 1–3. Exclusion was defined as ≥70% scoring 1–3 and <15% 7–9. Individual and group scores were fed back to participants alongside the second questionnaire round, which included outcomes for which no consensus had been achieved. Results: A long-list of 63 potential outcomes was identified. Refinement of this long-list of outcomes resulted in 29 outcomes, which were included in the Delphi questionnaire (round 1). Following both rounds of the Delphi exercise, 13 outcomes (organised into seven overarching domains: medication appropriateness, adverse drug events, prescribing errors, falls, quality of life, all-cause mortality and admissions to hospital (and associated costs)) met the criteria for inclusion in the final COS. Conclusions: We have developed a COS for effectiveness trials aimed at optimising prescribing in older adults in care homes using robust methodology. Widespread adoption of this COS will facilitate evidence synthesis between trials. Future work should focus on evaluating appropriate tools for these key outcomes to further reduce heterogeneity in outcome measurement in this context

    Evaluation of effectiveness and safety of pharmacist independent prescribers in care homes: cluster randomised controlled trial

    Get PDF
    Objective: To estimate the effectiveness, cost effectiveness (to be reported elsewhere), and safety of pharmacy independent prescribers in care homes. Design: Cluster randomised controlled trial, with clusters based on triads of a pharmacist independent prescriber, a general practice, and one to three associated care homes. Setting: Care homes across England, Scotland, and Northern Ireland, their associated general practices, and pharmacy independent prescribers, formed into triads. Participants: 49 triads and 882 residents were randomised. Participants were care home residents, aged ≥65 years, taking at least one prescribed drug, recruited to 20 residents/triad. Intervention: Each pharmacy independent prescriber provided pharmaceutical care to approximately 20 residents across one to three care homes, with weekly visits over six months. Pharmacy independent prescribers developed a pharmaceutical care plan for each resident, did medicines reviews/reconciliation, trained staff, and supported with medicines related procedures, deprescribing, and authorisation of prescriptions. Participants in the control group received usual care. Main outcomes measures: The primary outcome was fall rate/person at six months analysed by intention to treat, adjusted for prognostic variables. Secondary outcomes included quality of life (EQ-5D by proxy), Barthel score, Drug Burden Index, hospital admissions, and mortality. Assuming a 21% reduction in falls, 880 residents were needed, allowing for 20% attrition. Results: The average age of participants at study entry was 85 years; 70% were female. 697 falls (1.55 per resident) were recorded in the intervention group and 538 falls (1.26 per resident) in the control group at six months. The fall rate risk ratio for the intervention group compared with the control group was not significant (0.91, 95% confidence interval 0.66 to 1.26) after adjustment for all model covariates. Secondary outcomes were not significantly different between groups, with exception of the Drug Burden Index, which significantly favoured the intervention. A third (185/566; 32.7%) of pharmacy independent prescriber interventions involved medicines associated with falls. No adverse events or safety concerns were identified. Conclusions: Change in the primary outcome of falls was not significant. Limiting follow-up to six months combined with a small proportion of interventions predicted to affect falls may explain this. A significant reduction in the Drug Burden Index was realised and would be predicted to yield future clinical benefits for patients. This large trial of an intensive weekly pharmacist intervention with care home residents was also found to be safe and well received

    The Care Home Independent Pharmacist Prescriber Study (CHIPPS): development and implementation of an RCT to estimate safety, effectiveness and cost-effectiveness

    Background Medicine prescribing, monitoring and administration in care homes can be significantly enhanced. Effective interventions to improve pharmaceutical care and resident outcomes are required. The enablement of pharmacists to prescribe provides an opportunity for pharmacist independent prescribers to assume responsibility for improving pharmaceutical care, medication-related outcomes and resident safety whilst reducing general practitioner workload. Objective(s) To determine the effectiveness and cost-effectiveness of pharmacist independent prescribing in care homes. Design Development work was undertaken through five work packages before the delivery of the definitive trial. Triads of pharmacist independent prescribers, care home and general practice with responsibility over 20 care home residents were recruited and cluster randomised to intervention or usual care for 6 months. Researchers were blinded at recruitment stage only. Recruitment of 880 residents was required to provide 80% statistical power, to show a 21% reduction in falls over 6 months, assuming 20% attrition. Randomisation was undertaken electronically at triad level, stratified by geographical area. Intention-to-treat analysis undertaken using a negative binomial model. Parameters were estimated using a generalised estimating equation approach. Costs were captured from an NHS perspective. Quality of life (EuroQol; five domain; five level) was collected by proxy to enable cost/quality-adjusted life-year estimation. A concurrent process evaluation was performed. Safety was monitored through a review of pharmacist independent prescriber activities, independent concerns reporting and review of adverse events. Participants Forty-nine triads of general practitioners, pharmacist independent prescribers and care homes were recruited with 454 residents allocated to the intervention arm and 428 to the control arm. Intervention Medication review and care planning, medication reconciliation, staff training, support with care home medication-related procedures, deprescribing and authorisation of monthly prescriptions. Main outcome measure Fall rate per person over 6 months. Results Data for 449 intervention and 427 control residents available for final analysis. The 6-month fall rate ratio in favour of intervention was 0.91 (95% confidence interval 0.66 to 1.26; p=0.58). No significant difference in secondary outcomes was identified except Drug Burden Index (rate ratio 0.83, 95% confidence interval 0.75 to 0.92; p<0.001). No harms were identified. One quarter of medication-related interventions were associated with a reduced risk of falls. The intervention was positively received. Limitations Participant self-selection bias may have affected the generalisability of findings. Open-label cluster randomised controlled trial limited by 6-month follow-up. Potential ceiling effect due to concurrent pharmacist-led interventions. Falls potentially insufficiently proximal to the intervention. Conclusions To enhance effectiveness and acceptance of the proposed model, effective integration into care home and general practitioner teams was identified as a central requirement. A core outcome set and a training package were developed. The final model of care, whilst being safe and well received and resulting in a reduction in drug burden, demonstrated no improvement in the primary outcome of falls. With no improvement in quality-adjusted life-years identified, the pharmacist independent prescriber intervention was not estimated to be cost-effective. Future work To develop and evaluate better models of care for enhancing medication outcomes and safety in care homes or re-test with a longer intervention and follow-up period and a stronger primary outcome.

    Phosphatidylinositol 3-kinase (PI3K) pathway activation in bladder cancer

    Get PDF
    The phosphatidylinositol 3-kinase (PI3K) pathway is a critical signal transduction pathway that regulates multiple cellular functions. Aberrant activation of this pathway has been identified in a wide range of cancers. Several pathway components including AKT, PI3K and mTOR represent potential therapeutic targets and many small molecule inhibitors are in development or early clinical trials. The complex regulation of the pathway, together with the multiple mechanisms by which it can be activated, make this a highly challenging pathway to target. For successful inhibition, detailed molecular information on individual tumours will be required and it is already clear that different tumour types show distinct combinations of alterations. Recent results have identified alterations in pathway components PIK3CA, PTEN, AKT1 and TSC1 in bladder cancer, some of which are significantly related to tumour phenotype and clinical behaviour. Co-existence of alterations to several PI3K pathway genes in some bladder tumours indicates that these proteins may have functions that are not related solely to the known canonical pathway

    Peace and Justice through a Feminist Lens: Gender Justice and the Women’s Court for the Former Yugoslavia

    Get PDF
    Post-conflict interventions to ‘deal with’ violent pasts have moved from exception to global norm. Early efforts to achieve peace and justice were critiqued as ‘gender-blind’—for failing to address sexual and gender-based violence, and neglecting the gender-specific interests and needs of women in transitional settings. The advent of UN Security Council resolutions on ‘Women, Peace and Security’ provided a key policy framework for integrating both women and gender issues into transitional justice processes and mechanisms. Despite this, gender justice and equality in (post-)conflict settings remain largely unachieved. This article explores efforts to attain gender-just peace in post-conflict Bosnia and Herzegovina (BiH). It critically examines the significance of a recent ‘bottom-up’ truth-telling project—the Women’s Court for the former Yugoslavia—as a locally engaged approach to achieving justice and redress for women impacted by armed conflict. Drawing on participant observation, documentary analysis, and interviews with women activists, the article evaluates the successes and shortcomings of responding to gendered forms of wartime violence through truth-telling. Extending Nancy Fraser’s tripartite model of justice to peacebuilding contexts, the article advances notions of recognition, redistribution and representation as crucial components of gender-just peace. It argues that recognizing women as victims and survivors of conflict, achieving a gender-equitable distribution of material and symbolic resources, and enabling women to participate as agents of transitional justice processes are all essential for transforming the structural inequalities that enable gender violence and discrimination to materialize before, during, and after conflict
