RESUMEN

BACKGROUND: The Online Resource for Recruitment in Clinical triAls (ORRCA) and the Online Resource for Retention in Clinical triAls (ORRCA2) were established to organise and map the literature addressing participant recruitment and retention within clinical research. The two databases are updated on an ongoing basis using separate but parallel systematic reviews. However, recruitment and retention of research participants is widely acknowledged to be interconnected. While interventions aimed at addressing recruitment challenges can impact retention and vice versa, it is not clear how well they are simultaneously considered within methodological research. This study aims to report the recent update of ORRCA and ORRCA2 with a special emphasis on assessing crossover of the databases and how frequently randomised studies of methodological interventions measure the impact on both recruitment and retention outcomes. METHODS: Two parallel systematic reviews were conducted in line with previously reported methods updating ORRCA (recruitment) and ORRCA2 (retention) with publications from 2018 and 2019. Articles were categorised according to their evidence type (randomised evaluation, non-randomised evaluation, application and observation) and against the recruitment and retention domain frameworks. Articles categorised as randomised evaluations were compared to identify studies appearing in both databases. For randomised studies that were only in one database, domain categories were used to assess whether the methodological intervention was likely to impact on the alternate construct. For example, whether a recruitment intervention might also impact retention. RESULTS: In total, 806 of 17,767 articles screened for the recruitment database and 175 of 18,656 articles screened for the retention database were added as result of the update. Of these, 89 articles were classified as 'randomised evaluation', of which 6 were systematic reviews and 83 were randomised evaluations of methodological interventions. Ten of the randomised studies assessed recruitment and retention and were included in both databases. Of the randomised studies only in the recruitment database, 48/55 (87%) assessed the content or format of participant information which could have an impact on retention. Of the randomised studies only in the retention database, 6/18 (33%) assessed monetary incentives, 4/18 (22%) assessed data collection location and methods and 3/18 (17%) assessed non-monetary incentives, all of which could have an impact on recruitment. CONCLUSION: Only a small proportion of randomised studies of methodological interventions assessed the impact on both recruitment and retention despite having a potential impact on both outcomes. Where possible, an integrated approach analysing both constructs should be the new standard for these types of evaluations to ensure that improvements to recruitment are not at the expense of retention and vice versa.

RESUMEN

Policymakers often face a conundrum between being transparent about policies and ensuring that those policies are effective. This challenge is particularly relevant for behavioral nudges, which are not usually disclosed. Rather than avoiding transparency, we suggest that policymakers encourage citizens to reflect on nudges to help them understand their own views and align those views with their behaviors. Using data from an online survey experiment with 24,303 respondents in G7 countries, we examine the impact of reflection on a hypothetical default nudge policy for COVID-19 booster appointments. Contrary to expectations, participants say they would be less likely to get the booster when automatically enrolled compared with a control condition. Similarly, encouraging citizens to think about the status quo (baseline) policy also reduces intentions for boosters. These interventions have no effect on approval of the policy. Further, encouraging people to think about automatic enrollment decreases approval of the policy and further decreases their intentions to get vaccinated. These findings suggest that reflection on a nudge can increase backlash from a nudge and also elicit policy disapproval, thereby aligning policy support with behavioral intentions.

RESUMEN

Ordinary metals contain electron liquids within well-defined 'Fermi' surfaces at which the electrons behave as if they were non-interacting. In the absence of transitions to entirely new phases such as insulators or superconductors, interactions between electrons induce scattering that is quadratic in the deviation of the binding energy from the Fermi level. A long-standing puzzle is that certain materials do not fit this 'Fermi liquid' description. A common feature is strong interactions between electrons relative to their kinetic energies. One route to this regime is special lattices to reduce the electron kinetic energies. Twisted bilayer graphene1-4 is an example, and trihexagonal tiling lattices (triangular 'kagome'), with all corner sites removed on a 2 × 2 superlattice, can also host narrow electron bands5 for which interaction effects would be enhanced. Here we describe spectroscopy revealing non-Fermi-liquid behaviour for the ferromagnetic kagome metal Fe3Sn2 (ref. 6). We discover three C3-symmetric electron pockets at the Brillouin zone centre, two of which are expected from density functional theory. The third and most sharply defined band emerges at low temperatures and binding energies by means of fractionalization of one of the other two, most likely on the account of enhanced electron-electron interactions owing to a flat band predicted to lie just above the Fermi level. Our discovery opens the topic of how such many-body physics involving flat bands7,8 could differ depending on whether they arise from lattice geometry or from strongly localized atomic orbitals9,10.

RESUMEN

BACKGROUND: This paper aims to explore the impact of recovery education on recovery knowledge, attitudes and the quality of life of students undertaking recovery education, contributing to the evidence base in relation to the impact of recovery education. It also explores the experiences of all stakeholders involved in the co-facilitation, delivery and participation in recovery education. SETTING AND PARTICIPANTS: This study evaluates the experiences of stakeholders involved in the co-facilitation, delivery and participation in recovery education across four recovery colleges in Ireland. Participants included students undertaking recovery education, peer educators, education facilitators, recovery college coordinators and practitioner/service providers. DISCUSSION: Findings from the quantitative survey when compared with extant literature suggest that students had a good understanding of recovery education. The social aspect of empowerment for growth and wellbeing was identified through themes relating to co-production and facilitating student learning. Support for equitable access to recovery education, including co-production for both the public and staff, was identified as a challenge for the future. CONCLUSION: The findings from both the qualitative and quantitative components of the study show the positive impact of recovery education on stakeholders while acknowledging the need for ongoing support for people working in recovery education and the development of services. In particular, there was a high level of recovery knowledge found in students undertaking recovery education. PATIENT OR PUBLIC CONTRIBUTION: This study utilised a co-created study design. From inception a steering group comprising stakeholders (peer educators, recovery education facilitators including past recovery college students and nonpeer staff involved in the co-production of recovery education) directed the conduct of the evaluation. This steering group participated in an iterative process of information sharing, suggestions for evaluation process and language.

RESUMEN

INTRODUCTION: Stroke is the second-leading cause of death and disability globally. Participation in physical activity (PA) is a cornerstone of secondary prevention in stroke care. Given the heterogeneous nature of stroke, PA interventions that are adaptive to individual performance are recommended. Mobile health (mHealth) has been identified as a potential approach to supporting PA poststroke. To this end, we aim to use a Sequential Multiple Assignment Randomised Trial (SMART) design to develop an adaptive, user-informed mHealth intervention to improve PA poststroke. METHODS AND ANALYSIS: The components included in the 12-week intervention are based on empirical evidence and behavioural change theory and will include treatments to increase participation in Structured Exercise and Lifestyle or a combination of both. 117 participants will be randomly assigned to one of the two treatment components. At 6 weeks postinitial randomisation, participants will be classified as responders or non-responders based on participants' change in step count. Non-responders to the initial treatment will be randomly assigned to a different treatment allocation. The primary outcome will be PA (steps/day), feasibility and secondary clinical and cost outcomes will also be included. A SMART design will be used to evaluate the optimum adaptive PA intervention among community-dwelling, ambulatory people poststroke. ETHICS AND DISSEMINATION: Ethical approval has been granted by the Health Service Executive Mid-Western Ethics Committee (REC Ref: 026/2022). The findings will be submitted for publication and presented at relevant national and international academic conferences TRIALS REGISTRATION NUMBER: NCT05606770.

RESUMEN

Under what conditions do citizens support coercive public policies? Although recent research suggests that people prefer policies that preserve freedom of choice, such as behavioural nudges, many citizens accepted stringent policy interventions like fines and mandates to promote vaccination during the COVID-19 pandemic-a pattern that may be linked to the unusually high effectiveness of COVID-19 vaccines. We conducted a large online survey experiment (N = 42,417) in the Group of Seven (G-7) countries investigating the relationship between a policy's effectiveness and public support for stringent policies. Our results indicate that public support for stringent vaccination policies increases as vaccine effectiveness increases, but at a modest scale. This relationship flattens at higher levels of vaccine effectiveness. These results suggest that intervention effectiveness can be a significant predictor of support for coercive policies but only up to some threshold of effectiveness.

RESUMEN

Stroke is a leading cause of mortality and morbidity with a paucity of effective pharmacological treatments. We have previously identified insulin-regulated aminopeptidase (IRAP) as a potential target for the development of a new class of drugs for the treatment of stroke, as global deletion of this gene in mice significantly protected against ischemic damage. In the current study, we demonstrate that small molecular weight IRAP inhibitors reduce infarct volume and improve neurological outcome in a hypertensive animal model of ischemic stroke. The effects of two structurally distinct IRAP inhibitors (HFI419 or SJM164) were investigated in a model of stroke where the middle cerebral artery was transiently occluded with endothelin-1 in the conscious spontaneously hypertensive rat. IRAP inhibitor was administered into the lateral ventricle at 2 or 6 h after stroke, with subsequent doses delivered at 24, 48 and 70 h post-stroke. Functional outcomes were assessed prior to drug treatment, and on day 1 and 3 post-stroke. Histological analyses and neuroinflammatory cytokine profiling were conducted at 72 and 24 h post-stroke respectively. IRAP inhibitor treatment following stroke significantly reduced infarct volume and improved neurological and motor deficits. These protective effects were maintained even when the therapeutic window was extended to 6 h. Examination of the cellular architecture at 72 h post-stroke demonstrated that IRAP expression was upregulated in CD11b positive cells and activated astrocytes. Furthermore, IRAP inhibitor treatment significantly increased gene expression for interleukin 6 and C-C motif chemokine ligand 2 in the ischemic core. This study provides proof-of-principle that selective inhibition of IRAP activity with two structurally distinct IRAP inhibitors reduces infarct volume and improves functional outcome even when the first dose is administered 6 h post-stroke. This is the first direct evidence that IRAP inhibitors are a class of drug with potential use in the treatment of ischemic stroke.

RESUMEN

End-stage kidney disease (ESKD) has been shown to be correlated with an increased risk of COVID-19 infection and mortality. Remdesivir is an effective non-EUA U.S. Food and Drug Administration (FDA)-approved antiviral agent for the treatment of COVID-19 in hospitalized adult and pediatric patients, though a lack of data has prevented its use in patients with severe kidney disease including dialysis patients. Some observational studies report the use of remdesivir in hemodialysis patients, but there are no reports of patients treated with remdesivir on peritoneal dialysis. Dialysis modalities may affect drug pharmacokinetics, and safety and efficiency of remdesivir in peritoneal dialysis is unknown. We report the first case, to our knowledge, of using remdesivir in a patient treated with peritoneal dialysis with no significant adverse events. This case illustrates the potential for remdesivir to be considered in peritoneal dialysis patients with severe COVID infection. Proper risk analysis and careful monitoring should be done, given the unpredictable clearance of the drug.

RESUMEN

Chronic exposure to toxic metals is a serious global health concern. However, population-wide biomonitoring is costly and carries several sampling constraints. Though hair sampling can be a useful way to assess environmental exposure, external contamination is a long-standing concern, and a pre-cleaning step prior to metal quantification has long been recommended despite a lack of evidence for its efficacy. In this study, we quantified the spatial distribution of 16 elements in unwashed human hair samples using Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS), then tested how two common pre-cleaning treatments (Triton-ethanol, Triton-nitric acid) affected metal content in external and interior layers of hair using LA-ICP-MS. We show that elements differ in their spatial distribution across hair and that pre-cleaning is not consistent in its effect on element concentrations and decreases interior concentrations of some elements. We demonstrate that differences among individuals can be quantified reliably with LA-ICP-MS analysis of interior concentrations of unwashed hair. Our study tests the widespread notion that pre-cleaning is essential in analyses of hair for environmental exposure to metals, and examines the benefits of a unified approach to analysis of metals in hair using LA-ICP-MS.

RESUMEN

Black phosphorus (BP) stands out among two-dimensional (2D) semiconductors because of its high mobility and thickness dependent direct band gap. However, the quasiparticle band structure of ultrathin BP has remained inaccessible to experiment thus far. Here we use a recently developed laser-based microfocus angle resolved photoemission (µ-ARPES) system to establish the electronic structure of 2-9 layer BP from experiment. Our measurements unveil ladders of anisotropic, quantized subbands at energies that deviate from the scaling observed in conventional semiconductor quantum wells. We quantify the anisotropy of the effective masses and determine universal tight-binding parameters, which provide an accurate description of the electronic structure for all thicknesses.

RESUMEN

Background: Despite methodological improvements in clinical trial design and conduct more generally, methodological limitations persist in trials concerning mental health care. A qualitative Study Within A Trial (Qual-SWAT), embedded in the KARMA-Dep-2 host trial, will be undertaken to explore and gain an understanding of two methodological questions in randomised trials specific to mental health care: (1) what are the key barriers and enablers of participation in randomised trials in mental health; and (2) how can randomised trials become part of routine mental health care. These issues will be examined from patient-participant and clinician- / researcher-participant perspectives, in alignment with PRioRiTy research themes. Methods: A descriptive qualitative study design will be used. Data will be collected via one-to-one semi-structured interviews, conducted via Microsoft Teams. The interview data will be analysed using Braun and Clarke's Thematic Analysis approach. One-to-one interviews will be conducted with three participant groups ( N = 30): 1) host trial patient-participants ( n = 10); 2) potentially eligible host trial patient-participants who refused enrolment in the host trial ( n = 10); and 3) clinician- / researcher-participants who are associated with work on the host trial ( n = 10). Ethics and dissemination: Ethical approval has been granted by St. Patrick's Mental Health Services Research Ethics Committee, Ireland (Ref: Protocol 09/20). When the study is completed, a report will be prepared and submitted to the Health Research Board (HRB). Findings will be shared with the host trial team and study participants, and submitted for publication. Host trial registration: ClinicalTrials.gov ( NCT04939649); EudraCT ( 2019-003109-92).

RESUMEN

Few studies have explored how forensic mental health nurses can rebuild the therapeutic relationship following an episode of physical restraint in the acute forensic setting. In this study, we aimed to redress this gap in the literature by exploring with forensic mental health nurses the factors that enable or hinder the rebuilding of the therapeutic relationship following an episode of physical restraint. A qualitative study design was used to capture participants' experiences, views and perceptions of the therapeutic relationship following an episode of physical restraint in the acute forensic setting. Data were collected through individual interviews with forensic mental health nurses (n = 10) working in an acute forensic setting. Interviews were audio recorded, and transcribed verbatim and accounts were analysed using thematic analysis. Four themes were identified: 'Building a Recovery Focused Therapeutic Relationship'; 'Authoritarian Role'; 'Inevitable Imbalance'; 'Rebuilding the Therapeutic Relationship'; plus two sub-themes 'Facilitators to rebuilding' and 'Barriers to rebuilding'. Findings suggest that an inevitable imbalance exists in building a recovery-focused therapeutic relationship and at times, is hindered by the authoritarian role of the forensic mental health nurse. Recommendations for changes in clinical practice and in upcoming policies should incorporate a dedicated debrief room and protected time for staff to debrief effectively following restraint. Routine post-restraint-focused clinical supervision would also be beneficial to mental health nursing staff.

RESUMEN

Recent years have seen remarkable progress in our scientific understanding of early childhood social, emotional, and cognitive development, as well as our capacity to widely disseminate health information by using digital technologies. Together, these scientific and technological advances offer exciting opportunities to deliver high-quality information about early childhood development (ECD) to parents and families globally, which may ultimately lead to greater knowledge and confidence among parents and better outcomes among children (particularly in lower- and middle-income countries). With these potential benefits in mind, we set out to design, develop, implement, and evaluate a new parenting app-Thrive by Five-that will be available in 30 countries. The app will provide caregivers and families with evidence-based and culturally appropriate information about ECD, accompanied by sets of collective actions that go beyond mere tips for parenting practices. Herein, we describe this ongoing global project and discuss the components of our scientific framework for developing and prototyping the app's content. Specifically, we describe (1) 5 domains that are used to organize the content and goals of the app's information and associated practices; (2) 5 neurobiological systems that are relevant to ECD and can be behaviorally targeted to potentially influence social, emotional, and cognitive development; (3) our anthropological and cultural framework for learning about local contexts and appreciating decolonization perspectives; and (4) our approach to tailoring the app's content to local contexts, which involves collaboration with in-country partner organizations and local and international subject matter experts in ECD, education, medicine, psychology, and anthropology, among others. Finally, we provide examples of the content that was incorporated in Thrive by Five when it launched globally.

RESUMEN

WHAT IS KNOWN ON THE SUBJECT?: Research indicates many people accessing mental healthcare have trauma history and often experience re-traumatization in acute mental health inpatient settings. Treatment for trauma is not routinely explored as a treatment option in mental health inpatient settings and consequently mental health professionals do not draw connections between the person with trauma history and their presenting mental health problems. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: People in acute mental health inpatient units are not asked about their previous trauma histories on admission and their trauma history is not taken into consideration during interventions in particular coercive practices such as seclusion, restraint, forced medication, and involuntary admission. This paper provides an understanding on how to address trauma-related issues within in-patient settings and identifies practical examples of how to reduce the risk of re-traumatization. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Staff induction and training development needs can be used to help mental health professionals to be more confident and competent in assessing and identifying the history of trauma so that they can improve recognition, provide post-disclosure support, and avoid the potential for re-traumatization for inpatients. Physical environments need to be welcoming, homely, and have comfortable furnishing. They also require adequate space for inpatients to move around freely and have a quiet space to go to de-escalate themselves when required. ABSTRACT: INTRODUCTION: Rates of re-traumatization among mentally ill-health patients have risen significantly over the past decade and clinical guidelines place mental health nurses at the heart of their care. AIM: To gather, analyse, and synthesize the evidence on people's experiences on re-traumatization in acute mental health inpatient settings. METHOD: A systematic search for qualitative studies (CINAHL, MEDLINE, ASSIA, PsycINFO, and EMBASE) was conducted. Two authors independently assessed eligibility and appraised methodological quality using Joanna Briggs's quality appraisal tool and extracted data. The analysis followed the principles of interpretative synthesis. RESULTS: Fourteen papers were included for thematic synthesis. Three themes emerged: (1) Quality of staff interaction; (2) Specific interventions, (Sub-theme nature of symptoms); and (3) Nature of the environment. DISCUSSION: Our findings demonstrate that patients are experiencing re-traumatization in acute mental health inpatient settings and that there is little being done to prevent it from occurring. IMPLICATIONS FOR PRACTICE: This study is the first to analyse the factors that contribute to re-traumatization and make recommendations to mental healthcare professionals to reduce the harmful practices in place in inpatient settings. It is suggested that training staff in trauma-informed care and allowing patients to be experts in their own care can reduce the rates of re-traumatization.

RESUMEN

Background: During a surge of COVID-19 cases, the volume of acute care patients with hypoxemic respiratory failure placed a high burden of responsibility on internal medicine, pulmonary and critical care medicine, and clinical pharmacy services. Observations: We describe the COVID-19 Tele-Huddle Program, a novel approach to communication between key stakeholders in COVID-19 patient care through a daily video conferencing huddle. The program was implemented during a 4-week surge in COVID-19 cases at a large, academic medical center in Houston, Texas. Data collected during the COVID-19 Tele-Huddle Program included the type and number of interventions implemented, number of patients discussed, and COVID-19 therapies provided. In addition, hospital medicine team members completed a user-experience survey. Conclusions: A multidisciplinary consultation service using video conferencing can support the care of patients with high disease severity without overwhelming existing inpatient medical, intensive care, and pharmacy services.

RESUMEN

Background: Mortality from non-small cell lung cancer (NSCLC) has improved with screening and novel treatments. The substance use epidemic has threatened health outcomes in a variety of diseases, but little is known about how it is associated with NSCLC outcomes. Methods: We performed a retrospective cohort study of 211 patients with NSCLC treated at a safety-net hospital. Sociodemographic data and clinical outcomes were extracted via review of electronic medical records. Patients were stratified based on substance use status. Comparative and multivariable analyses were performed to evaluate baseline characteristics and lung cancer outcomes including survival. Results: Among 193 patients (91.5%) with information available on substance use, 24.9% reported substance use; specifically, alcohol, marijuana, and illicit substances. Patients with substance use were more likely to have increased health care utilization and poor social determinants of health, including safe housing, stable employment, and social support. There were no significant differences in treatment adherence. Only 6.3% of patients with substance use did not receive guideline concordant care (GCC) compared to 24.8% of patients without substance use; due to poor performance status, increased comorbidities, or loss to follow up. On univariable analysis, patients with substance use experienced inferior median overall survival (OS) if they had metastatic disease (0.40 vs. 1.03 years, P=0.01). However, in the multivariable analysis, substance use did not predict for survival. Independent predictors of mortality were sex (male HR, 1.67; 95% CI: 1.04-2.68; P=0.04), smoking status (current smoking HR, 2.63; 95% CI: 1.14-6.08; P=0.02), and stage (stage IV HR, 14.96; 95% CI: 6.28-35.63; P=0.008). Conclusions: Substance use is associated with poor social determinants of health and increased health care utilization. On multivariable analysis, substance use was not independently associated with OS once guideline-concordant care was used. Future studies should focus on improving our understanding of these associations, delineating potential mechanisms, and developing evidence-based strategies to reduce health care utilization and overcome challenges related to poor social determinants of health.

RESUMEN

Success in a soccer penalty can be the difference between winning and losing matches. The outcome is determined by a complex interaction between the shooter and goalkeeper, whose performances are constrained by biomechanical trade-offs. To overcome these performance constraints, each player has a range of available strategies. Shooters can kick at different speeds, affecting accuracy, while goalkeepers can move at various times (leave-times), affecting the time available to move and the probability they move in the correct direction. Previous models of penalty success ignore such trade-offs and how they interact to influence the outcome. Here, we present a model that accounts for shooting inaccuracy to predict the probability of success for all shooting strategies, defined as any combination of: shot speed, position where the shooter aims, shooter footedness, and kicking technique (side-foot or instep). To estimate the probability of success each shooting strategy is matched against all possible goalkeeper leave-times, considering the probability each leave-time is chosen. We test the model against an average goalkeeper and a goalkeeper who tends to move later. Against the average goalkeeper, aiming on the ground toward the centre of the goal is optimal; however, against a late moving goalkeeper, aiming on the ground to the extremities of the goal is effective, with the optimal target in the horizontal dimension dependent on shot speed, kick technique, and footedness. Coaches could use this model to identify their best penalty takers and each players' optimal shooting strategy against either the average goalkeeper or a specific goalkeeper.

RESUMEN

BACKGROUNDS: Locally invasive T4 rectal cancer often requires neoadjuvant treatment followed by multi-visceral surgery to achieve a radical resection (R0), and referral to a specialized exenteration quaternary centre is typically recommended. The aim of this study was to explore regional variance in treatment and outcomes of patients with locally advanced rectal cancer in Australia and New Zealand (ANZ). METHODS: Data were collected from the Bi-National Colorectal Cancer Audit (BCCA) database. Rectal cancer patients treated between 2007 and 2019 were divided into six groups based on region (state/country) using patient postcode. A subset analysis of patients with T4 cancer was performed. Primary outcomes were positive circumferential resection margin (CRM+), and positive circumferential and/or distal resection margin (CRM/DRM+). RESULTS: A total of 9385 patients with rectal cancer were identified, with an overall CRM+ rate of 6.4% and CRM/DRM+ rate of 8.6%. There were 1350 patients with T4 rectal cancer (14.4%). For these patients, CRM+ rate was 18.5%, and CRM/DRM+ rate was 24.1%. Significant regional variation in CRM+ (range 13.4-26.0%; p = 0.025) and CRM/DRM+ rates (range 16.1-29.3%; p = 0.005) was identified. In addition, regions with higher CRM+ and CRM/DRM+ rates reported lower rates of multi-visceral resections: range 24.3-26.8%, versus 32.6-37.3% for regions with lower CRM+ and CRM/DRM+ rates (p < 0.0001). CONCLUSION: Positive resection margins and rates of multi-visceral resection vary between the different regions of ANZ. A small subset of patients with T4 rectal cancer are particularly at risk, further supporting the concept of referral to specialized exenteration centres for potentially curative multi-visceral resection.

RESUMEN

BACKGROUND: The Irish Office of Nursing & Midwifery Services Director (ONMSD) commissioned the development an updated suite of mental health nursing metrics and indicators for implementation in Irish mental health clinical settings. While measuring care processes does offer the potential to improve care quality, the choice of which mental health nursing metrics to measure presents a significant challenge, both in Ireland and internationally. The provision of safe and high-quality mental health nursing care stems from nurses' expertise, skills and overall capacity to provide recovery focused care across a range of health care settings. Accordingly, efforts to measure what mental health nurses do depends on the identification of those care processes that contribute to mental health nursing practice. This paper reports on the identification, development and prioritisation of a national suite of Quality Care Metrics (QCM), along with their associated indicators, for mental health nursing care processes in Ireland. METHODS: The study was undertaken over four phases; i) a systematic literature review to identify mental health care process metrics and their associated indicators of measurement; ii) a two-round, online Delphi survey of mental health nurses to develop consensus on the suit of mental health nursing care process metrics; iii) a two-round online Delphi survey of mental health nurses to develop consensus on the indicators to be used to measure the agreed metrics; and iv) a face-to-face consensus meeting with mental health nurses and service user representatives to develop consensus on the final suite of metrics and indicators. RESULTS: Following these four phases 9 metrics and their 71 associated indicators were agreed for inclusion in the final suite of Mental Health Nursing QCM. These metrics are applicable across the life span and the range of mental health nursing health care settings. CONCLUSION: The development of this suite of Mental Health Nursing QCM and their indicators represents an opportunity for the measurement of safe and high-quality mental health nursing care for application in Ireland and internationally. This initial development of metrics and indicators should be followed by a rigorous baseline review of QCM uptake and implementation amongst mental health nurses as part of an ongoing evaluation.
