RESUMEN

BACKGROUND: Scalable and safe approaches for heart failure guideline-directed medical therapy (GDMT) optimization are needed. OBJECTIVES: The authors assessed the safety and effectiveness of a virtual care team guided strategy on GDMT optimization in hospitalized patients with heart failure with reduced ejection fraction (HFrEF). METHODS: In a multicenter implementation trial, we allocated 252 hospital encounters in patients with left ventricular ejection fraction ≤40% to a virtual care team guided strategy (107 encounters among 83 patients) or usual care (145 encounters among 115 patients) across 3 centers in an integrated health system. In the virtual care team group, clinicians received up to 1 daily GDMT optimization suggestion from a physician-pharmacist team. The primary effectiveness outcome was in-hospital change in GDMT optimization score (+2 initiations, +1 dose up-titrations, -1 dose down-titrations, -2 discontinuations summed across classes). In-hospital safety outcomes were adjudicated by an independent clinical events committee. RESULTS: Among 252 encounters, the mean age was 69 ± 14 years, 85 (34%) were women, 35 (14%) were Black, and 43 (17%) were Hispanic. The virtual care team strategy significantly improved GDMT optimization scores vs usual care (adjusted difference: +1.2; 95% CI: 0.7-1.8; P < 0.001). New initiations (44% vs 23%; absolute difference: +21%; P = 0.001) and net intensifications (44% vs 24%; absolute difference: +20%; P = 0.002) during hospitalization were higher in the virtual care team group, translating to a number needed to intervene of 5 encounters. Overall, 23 (21%) in the virtual care team group and 40 (28%) in usual care experienced 1 or more adverse events (P = 0.30). Acute kidney injury, bradycardia, hypotension, hyperkalemia, and hospital length of stay were similar between groups. CONCLUSIONS: Among patients hospitalized with HFrEF, a virtual care team guided strategy for GDMT optimization was safe and improved GDMT across multiple hospitals in an integrated health system. Virtual teams represent a centralized and scalable approach to optimize GDMT.

RESUMEN

PURPOSE: An evaluation of musculoskeletal risks for users of ophthalmic imaging equipment and subsequent trials based on recommendations by an Ergonomist. METHODS: An advertisement was posted on ophthalmic imaging social media sites, requesting photographers, who are experiencing pain or discomfort when using the imaging equipment, to contact the author. Responders received a questionnaire that created a profile of the working habits, equipment used, and location of discomfort using diagrams of the torso and hands. The author contacted the Centre for Occupational Health and Wellbeing in Oxford for recommendations and assessment of the imaging equipment. Trials were conducted at the Oxford Eye Hospital imaging department following recommendations by an Ergonomist. DISCUSSION: Our research has indicated that the number of imaging procedures carried out by a photographer over the duration of their career, may be the key to calculating the risk factors for developing Musculoskeletal Disorders. Ergonomist recommendations include increasing awareness of wrist and hand pain, so it can be treated early with implementation of risk assessment for working practices, as trials carried out at the imaging department in Oxford have shown that small changes contribute to reducing identified risks.

RESUMEN

Historically, treatment of heparin-induced thrombocytopenia (HIT) includes a non-heparin parenteral anticoagulant with bridging to warfarin once platelets recover. Data supporting the use of direct oral anticoagulants (DOACs) for HIT treatment are limited. Given the paucity of evidence for the use of DOACs in HIT, the aim of this study is to describe the prescribing patterns of DOACs for HIT at our institution. This is a single center, retrospective chart evaluation of patients admitted from January 2017 to October 2020 with a confirmed diagnosis of HIT. Twenty-six patients were identified; 21 patients (81%) received initial parenteral treatment and 5 patients (19.2%) with initial DOAC treatment. The most frequently used DOAC was apixaban at the VTE treatment dose [15 (57.7%)] followed by the reduced dose of apixaban [5 (19.2%)]. Of the patients initially treated with a parenteral agent, 11 (42.3%) were transitioned to a DOAC after platelet recovery, 7 (26.9%) transitioned as platelets were steadily increasing, and 3 (11.5%) transitioned at the time of discharge (prior to platelet recovery). Platelet recovery was achieved in 23 patients (88.5%) at a median of 5 days (IQR 2.8-8.3) after HIT diagnosis. No new thrombotic or bleeding events occurred within 30 days of HIT diagnosis. In our patients treated with a DOAC for HIT, no progression of HIT was observed. Apixaban was the most frequently utilized DOAC. Most patients received a parenteral anticoagulant prior to DOAC initiation. All patients managed with a DOAC as initial treatment achieved platelet recovery within 30 days of HIT diagnosis.

RESUMEN

BACKGROUND: The menstrual needs of girls and women are important to health, education, and well-being. Unmet need and harm from poor menstrual health in low-and- middle-income countries have been documented, but with little empirical research undertaken in high income countries. Continuing austerity in the UK suggests menstruators are likely more vulnerable to 'period poverty' than previously, with the COVID-19 pandemic assumed to exacerbate the situation. AIM: To explore the menstrual experiences and perceptions of women in the UK who are living under circumstances of deprivation, alongside views of staff working in organisations supporting these women, to understand whether women's menstrual needs are met. METHODS: A qualitative study was conducted in an inner-city in NW England. Three focus group discussions and 14 in-depth interviews were conducted across three study sites supporting impoverished women. Data was analysed thematically. RESULTS: Themes were: reflections on menstruation; affordability of products; access to public facilities; organisational support; potential solutions. Many women perceived menstruation as a burden in three aspects: physical discomfort and pain; psychological anxiety; and shame and stigma. Managing menstruation was difficult due to cost relative to low incomes, with food, heating and lighting prioritised, leaving women improvising with materials or wearing products for longer than desired. Most suggested that products should be free, often remarking if men required similar items this would happen. Most women were unaware supporting organisations provided free products. Staff felt the small range of products offered did not meet client needs and were ill-prepared to have conversations on products and clients' menstrual needs. CONCLUSION: Impoverished women lack the necessary resources to manage their menses well which negatively impacts their health and brings stress, embarrassment, and shame. Support, including access to free products, is needed at both local and national level to help impoverished women manage their menstrual hygiene.

RESUMEN

BACKGROUND: Antifibrinolytic agents, tranexamic acid (TXA) and epsilon-aminocaproic acid (EACA), are often used during cardiac surgery to decrease the number of allogenic blood transfusions and to prevent perioperative bleeding. Weight-based TXA dosing regimens have been compared to fixed-dose regimens of EACA with variable outcomes in perioperative blood product transfusions and chest tube output. Serious adverse events, including seizures, have been reported with higher doses of TXA. Fixed-dose TXA regimens have been evaluated in trauma and orthopedic surgery but there is a paucity of evidence in the cardiac surgery population. AIMS OF THE STUDY: To compare the safety and efficacy of fixed-dose TXA versus EACA in patients undergoing cardiac surgery. METHODS: A single-center, retrospective chart review was conducted at a 793-bed tertiary care academic teaching hospital comparing cardiac surgery patients receiving either fixed-dose TXA 1000 mg followed by a 500-1000 mg infusion or EACA-7.5 g intravenous boluses followed by a 1-1.25 g/h infusion for the duration of the surgery. The major endpoint included chest tube output at 12 h, 24 h, and 7 days postoperatively. Minor endpoints included quantity and incidence of blood product transfusions and reported safety events. RESULTS: There were 1544 patients included. Chest tube output was similar between groups and the TXA group required more intraoperative blood product transfusions (22.7% vs. 18.2%, p = .03). There were no differences in the median quantity of total blood products administered postoperatively at 24 h or at 7 days. Reported safety events were similar between groups. CONCLUSION: Both fixed-dose TXA and EACA may be considered safe and effective options for antifibrinolytic therapy in cardiac surgery patients.

RESUMEN

OBJECTIVE: In 2017, interns were permitted to work continuously for up to 28 hours at a time, a reversal from the previously mandated 16-hour limit. Our objective was to evaluate perceptions of care and patient outcomes on an extended (28-hour) compared with a limited (16-hour) duty-hour system on identical interdisciplinary teams. METHODS: Sixty-two interns, 27 residents, 28 attendings, and 449 patients participated. Patients completed surveys assessing their satisfaction. Anonymous weekly surveys were obtained from interns, residents, and attendings evaluating perceptions of intern tiredness, overall satisfaction, and performance. Nursing surveys evaluated intern and medical team performance. Objective outcome measures, including intensive care unit transfers, length of stay, readmissions, mortality, and complications, were assessed through a retrospective, blinded chart review. RESULTS: Patients reported similar satisfaction in care. Extended duty-hour interns reported significantly decreased familiarity with their patients, decreased ability to conduct physical exams on new patients, increased tiredness, and decreased overall satisfaction. Residents overseeing extended-duty interns reported significantly decreased quality in intern presentations and overall quality of teaching, and increased perception of intern tiredness and increased incorrect orders. Attending physicians reported significantly improved quality of new patient presentations by extended duty-hour interns. No significant differences in patient objective outcome measures were noted. CONCLUSIONS: Extended intern duty hours do not affect patient's satisfaction with their care. Although interns in the extended duty-hour system reported significantly increased fatigue and decreased overall satisfaction and residents' perceived increases in incorrect intern orders in the extended duty-hour system, there were no detrimental effects on patient safety.

RESUMEN

Evidence syntheses that engage librarians as co-authors produce higher-quality results than those that do not. Trained as teachers, researchers, and information managers, librarians possess expert knowledge on research methodologies and information retrieval approaches that are critical for evidence synthesis. Researchers are under increasing pressure to produce evidence syntheses to inform practice and policymaking. Many fields outside of health science and medicine, however, do not have established guidelines, processes, or methodologies. This article describes how librarians led the creation of an interdisciplinary toolkit for researchers new to evidence synthesis. The implementation of the tools, including a protocol, supported eight evidence syntheses focused on effective agricultural interventions published in a special collection in Nature Research in October 2020. This article is a step-by-step overview of the tools and process. We advocate that librarian collaboration in evidence synthesis must become the norm, not the exception. Evidence synthesis project leads without access to a qualified librarian may use this toolkit as a point of entry for production of transparent, reproducible reviews.

RESUMEN

BACKGROUND: Diagnosing heparin-induced thrombocytopenia (HIT) in patients with end-stage renal disease (ESRD) can be difficult, as they are frequently exposed to heparin and have multiple etiologies for thrombocytopenia. OBJECTIVE: To correlate 4T scores, IgG heparin-platelet factor 4 (PF4-heparin) ELISA results, and serotonin release assay (SRA) results in patients with ESRD. METHODS: We performed a retrospective review of patients with ESRD (creatinine clearance < 15 mL/min or on renal replacement therapy [RRT]) who underwent PF4-heparin ELISA testing from October 2015 to September 2019. True-positive PF4s required an intermediate to high 4T score (≥4), a positive SRA, and receipt of treatment for a HIT diagnosis. False-positive PF4s were defined as a positive PF4 with a negative SRA, low 4T score (<4), or lack of treatment for HIT. Indeterminant cases were classified on the basis of clinical assessment by the treating team (eg, hematology or vascular medicine). RESULTS: Of 254 patients with ESRD (92% on RRT), 29 patients (11.4%) had a positive PF4. Eleven (37.9%) had a confirmed diagnosis of HIT: 10 patients who met all of the above criteria, and one who met the 4T criteria and was treated for HIT but did not have SRA testing due to high clinical suspicion and a positive PF4 test. False-positive PF4 values occurred in 8 patients (27.5%). Of 10 (34.5%) indeterminant cases of patients with a negative SRA but intermediate to high 4T and positive PF4, only 3 patients were treated for HIT, whereas the other 7 were judged not to have HIT as assessed by the treating clinician. In patients with an intermediate to high 4T score and PF4 optical density > 0.4 but negative SRA, who were not treated for HIT, there were no adverse outcomes documented such as new or progressive thrombosis. CONCLUSION: In our ESRD population, 4T scores and PF4 testing were not predictive of a clinical diagnosis of HIT.

RESUMEN

BACKGROUND: There is limited guidance regarding the use of anticoagulation in patients on intra-aortic balloon pumps (IABP). The purpose of this study is to compare the safety outcomes in anticoagulated versus non-anticoagulated patients with an IABP. METHODS: This was a single center, retrospective chart review of patients admitted to the coronary care unit or cardiac surgery unit who received an IABP from May 2015 to July 2018. Patients who were anticoagulated with heparin while on an IABP were compared to those who were not anticoagulated. Major endpoints included a composite of thrombotic events and a composite of bleeding events. The major composite endpoint of thrombotic events included the incidence of ischemic stroke, any venous thromboembolism, device thrombosis, and limb ischemia. The major composite endpoint of bleeding events included major access site bleeding, minor access site bleeding, major non-access site bleeding, and minor non-access site bleeding. Minor endpoints included any major endpoint events occurring within 24 and 48 h of IABP insertion, hospital length of stay, intensive care unit length of stay, and in-hospital mortality. RESULTS: A total of 185 patients were evaluated for inclusion and 147 were included in the final analysis. There were 82 and 65 patients in the heparin and non-heparin groups, respectively. The composite endpoint of thrombotic events occurred in 7.3 and 7.7% in the heparin and non-heparin groups, respectively (p = 1). The composite bleeding endpoint occurred in 20.7 and 20.0% in the heparin and non-heparin groups, respectively (p = 0.91). There were no differences found in minor endpoints between groups. CONCLUSION: There were no significant differences found in major endpoints of bleeding and thrombotic events in patients who received anticoagulation while on an IABP versus those who did not receive anticoagulation.

RESUMEN

PURPOSE: Cardiac surgery patients frequently require anticoagulation. Warfarin remains the preferred agent, and a few trials have reported negative outcomes with the use of direct-acting oral anticoagulants (DOACs) in these patients. Therefore, limited literature exists that supports the dosing, safety, and efficacy of DOACs within the cardiac surgery population. METHODS: This single-center, retrospective analysis was conducted at a tertiary academic medical center. All data were extrapolated from electronic medical records of qualifying patients from August 2017 to August 2019. Adult patients were included if they received at least 1 of 4 DOACs (apixaban, rivaroxaban, edoxaban, or dabigatran) after undergoing one of the following cardiac surgeries: coronary artery bypass graft, bioprosthetic valve replacement, aortic surgery, or valve repair. The composite safety end point included major bleeding and clinically relevant nonmajor bleeding, as defined by the International Society on Thrombosis and Hemostasis. The composite efficacy outcome of thromboembolic events included deep vein thrombosis, pulmonary embolism, ischemic stroke, and intracardiac thrombus. FINDINGS: A total of 305 patient charts were identified for analysis; 229 patients met the inclusion criteria. The composite safety outcome occurred in 12 patients (5.2%) within 90 days after cardiac surgery. One patient (0.4%) experienced a thromboembolic event within 90 days after cardiac surgery. The most commonly prescribed DOAC was apixaban (79.0%). US Food and Drug Administration-approved dosing was used in 91.3% of patients, and DOACs were primarily used for the indication of stroke prevention in atrial fibrillation or atrial flutter (88.2%). IMPLICATIONS: These data provide insight into the prescribing practices, efficacy, and safety of DOACs in cardiac surgery patients.

RESUMEN

AIMS: Implementation of guideline-directed medical therapy (GDMT) for heart failure with reduced ejection fraction (HFrEF) remains incomplete. Non-cardiovascular hospitalization may present opportunities for GDMT optimization. We assessed the efficacy and durability of a virtual, multidisciplinary 'GDMT Team' on medical therapy prescription for HFrEF. METHODS AND RESULTS: Consecutive hospitalizations in patients with HFrEF (ejection fraction ≤40%) were prospectively identified from 3 February to 1 March 2020 (usual care group) and 2 March to 28 August 2020 (intervention group). Patients with critical illness, de novo heart failure, and systolic blood pressure <90 mmHg in the preceeding 24 hs prior to enrollment were excluded. In the intervention group, a pharmacist-physician GDMT Team provided optimization suggestions to treating teams based on an evidence-based algorithm. The primary outcome was a GDMT optimization score, the sum of positive (+1 for new initiations or up-titrations) and negative therapeutic changes (-1 for discontinuations or down-titrations) at hospital discharge. Serious in-hospital safety events were assessed. Among 278 consecutive encounters with HFrEF, 118 met eligibility criteria; 29 (25%) received usual care and 89 (75%) received the GDMT Team intervention. Among usual care encounters, there were no changes in GDMT prescription during hospitalization. In the intervention group, ß-blocker (72% to 88%; P = 0.01), angiotensin receptor-neprilysin inhibitor (6% to 17%; P = 0.03), mineralocorticoid receptor antagonist (16% to 29%; P = 0.05), and triple therapy (9% to 26%; P < 0.01) prescriptions increased during hospitalization. After adjustment for clinically relevant covariates, the GDMT Team was associated with an increase in GDMT optimization score (+0.58; 95% confidence interval +0.09 to +1.07; P = 0.02). There were no serious in-hospital adverse events. CONCLUSIONS: Non-cardiovascular hospitalizations are a potentially safe and effective setting for GDMT optimization. A virtual GDMT Team was associated with improved heart failure therapeutic optimization. This implementation strategy warrants testing in a prospective randomized controlled trial.

RESUMEN

BACKGROUND: Depression is common in nursing homes, particularly among newly admitted residents. This cluster randomised controlled trial evaluated the effectiveness of the Program to Enhance Adjustment to Residential Living (PEARL) in reducing depression in this group. METHODS: Participants were 219 newly-admitted residents (mean of 4.4 weeks since admission) in 42 nursing homes in Melbourne, Australia, with a mean age of 85.5 years (SD = 7.3). Nursing homes were randomly allocated to the intervention or standard care condition. Level of depressive symptoms was evaluated at baseline (T1), one week post- intervention (T2), 2 months post-intervention (T3, primary end point), and 6 months post-intervention (T4). Changes in depressive symptoms in the intervention and control groups over time were compared using a multilevel model, with nursing homes modelled as random intercept. RESULTS: In intention to treat analyses, depressive symptoms reduced from T1 to T3 to a greater degree in the intervention condition (Mchange=2.56, SDchange=5.71) than in the control (Mchange=0.63, SDchange=5.25), with a significant, small-medium treatment effect size (p=.035; Cohen's d=0.36). The reduction in depressive symptoms from T1 to T4 was not significant (p=.369; Cohen's d=0.32). LIMITATIONS: The findings require replication, particularly comparing PEARL with an active control condition. CONCLUSIONS: PEARL is a simple, brief program that was effective in reducing symptoms of depression in newly admitted nursing home residents.

RESUMEN

Survivors of childhood cancer treated with cranial irradiation are at risk of cerebrovascular disease (CVD), but the risks beyond age 50 are unknown. In all, 13457 survivors of childhood cancer included in the population-based British Childhood Cancer Survivor Study cohort were linked to Hospital Episode Statistics data for England. Risk of CVD related hospitalisation was quantified by standardised hospitalisation ratios (SHRs), absolute excess risks and cumulative incidence. Overall, 315 (2.3%) survivors had been hospitalised at least once for CVD with a 4-fold risk compared to that expected (95% confidence interval [CI]: 3.7-4.3). Survivors of a central nervous system (CNS) tumour and leukaemia treated with cranial irradiation were at greatest risk of CVD (SHR = 15.6, 95% CI: 14.0-17.4; SHR = 5.4; 95% CI: 4.5-6.5, respectively). Beyond age 60, on average, 3.1% of CNS tumour survivors treated with cranial irradiation were hospitalised annually for CVD (0.4% general population). Cumulative incidence of CVD increased from 16.0% at age 50 to 26.0% at age 65 (general population: 1.4-4.2%). In conclusion, among CNS tumour survivors treated with cranial irradiation, the risk of CVD continues to increase substantially beyond age 50 up to at least age 65. Such survivors should be: counselled regarding this risk; regularly monitored for hypertension, dyslipidaemia and diabetes; advised on life-style risk behaviours. Future research should include the recall for counselling and brain MRI to identify subgroups that could benefit from pharmacological or surgical intervention and establishment of a case-control study to comprehensively determine risk-factors for CVD.

RESUMEN

Many in vitro gastrointestinal models have been developed with the hope that they will continue to improve in their similarity to the organs from which they were isolated. Intestinal organoids isolated from various species are now being used to investigate physiology and pathophysiology. In this study, intestinal stem cells were isolated from adult rat duodenum and culture conditions were optimized to promote the growth, differentiation and development of 3D organoids. We optimized and characterized rat duodenal organoids with light and electron microscopy, immunofluorescence and notably, global mRNA expression. The metabolic capacity of these cultures was investigated using probe substrates for multiple phase I and phase II drug metabolizing enzymes and found to be in line with previous results from intestinal primary cultures and a significant improvement over immortalized cell lines. Over the course of differentiation, the gene expression profiles of the rat duodenal organoids were consistent with expected trends in differentiation to various cell lineages reflecting the duodenum in vivo. Further, incubations of these cultures with naproxen and celecoxib resulted in cytotoxicity consistent with the direct cytotoxic effects of these drugs to duodenum in vivo. Based on these characteristics, the rat duodenal organoids described herein will provide a novel platform for investigating a wide variety of mechanistic questions.

RESUMEN

Current guidelines recommend the consideration of positive inotropes in patients with acute decompensated heart failure (ADHF) who have low cardiac index and evidence of systemic hypoperfusion or congestion. However, there is no evidence detailing the first line agent for the management of ADHF. The purpose of this study was to compare the safety and efficacy of dobutamine to milrinone for the treatment of ADHF. This was a single-center, retrospective study at a tertiary academic medical center, approved by Partner's Health Care Institutional Review Board. Patients included in this study were those admitted with ADHF who received dobutamine or milrinone from June 2015 to July 2017. A total of 95 dobutamine and 40 milrinone patients were included in the analysis. Median hospital length of stay was 12 days in the dobutamine group versus 10 days in the milrinone group (P = 0.34). Rehospitalization within 30 days occurred in 29.5% of patients in the dobutamine group versus 17.5% of patients in the milrinone group (P = 0.15). Median intensive care unit length of stay was 4.5 days in the dobutamine group versus 10 days in the milrinone group (P < 0.01). All other minor end points including all-cause mortality, progression to renal failure within 72 hours, rehospitalization in 90 days, and urine output within 72 hours of therapy were not found to be statistically significant. In addition, a post hoc analysis compared major and minor outcomes between milrinone and dobutamine using linear and logistic regression with adjustment for baseline characteristics. There were not any statistically significant findings in the post hoc analysis. Overall, there were no statistically significant differences in outcomes between the 2 groups other than longer intensive care unit length of stay in the milrinone group.

RESUMEN

Farmers' organizations (FOs), such as associations, cooperatives, self-help and women's groups, are common in developing countries and provide services that are widely viewed as contributing to income and productivity for small-scale producers. Here, we conducted a scoping review of the literature on FO services and their impacts on small-scale producers in sub-Saharan Africa and India. Most reviewed studies (57%) reported positive FO impacts on farmer income, but much fewer reported positive impacts on crop yield (19%) and production quality (20%). Environmental benefits, such as resilience-building and improved water quality and quantity were documented in 24% of the studies. Our analysis indicates that having access to markets through information, infrastructure, and logistical support at the centre of FO design could help integrate FOs into policy. Natural resource management should also be more widely incorporated in the services provided by FOs to mitigate risks associated with environmental degradation and climate change. Finally, farmers who are already marginalized because of poor education, land access, social status and market accessibility may require additional support systems to improve their capacities, skills and resources before they are able to benefit from FO membership.

RESUMEN

Background and objectives: The purpose of this study was to examine the relationship between motor competence, body mass index (BMI), and nutrition knowledge in children with autism spectrum disorder (ASD). Materials and Methods: Fifty-one children with ASD (five females and 46 males) aged 7-12 participated in the study. The Movement Assessment Battery for Children-2 (MABC-2) was used to examine children's fine and gross motor skill competence; the nutrition knowledge survey assessed children's overall knowledge of food groups and healthful eating; and BMI-for-age determined their weight status. Descriptive analysis and Pearson correlation was used to analyze the relationship between nutrition knowledge, BMI, and motor competence in children with ASD. Results: The majority of children with ASD (82%) showed significant motor delays in MABC-2 assessments. The BMI-for-age percentile data suggested that 20% of participants were obese, 17% were overweight, and 12% were underweight. The nutrition knowledge data indicated that 55% of children scored below 70% on accuracy in the nutrition knowledge survey. Pearson correlation analysis revealed a significant positive relationship between MABC-2 manual dexterity and nutrition knowledge (r = 0.327, p < 0.01), and between MABC-2 balance skills and nutrition knowledge (r = 0.413, p < 0.01). A significant negative relationship was also found between BMI and MABC-2 balance skills (r = -0.325, p < 0.01). Conclusions: The findings of the study suggest that nutrition knowledge and motor competence may be key factors influencing BMI in children with ASD and therefore interventions tackling both sides of the energy balance equation are necessary.

RESUMEN

This study examines the need for, and outcomes of, a psychotherapeutic skills training programme, within an acute psychogeriatric unit. Nursing staff were surveyed to explore their training needs in psychotherapeutic skills with inpatients diagnosed with depressive, anxiety, or neurocognitive disorders. Staff were then invited to participate in a focus group (n = 6) to identify content of such training, possible barriers, and an implementation strategy. Next, to ascertain the feasibility and acceptability of such training, materials and schedules were developed and piloted with a small group of nurses (n = 8), before being administered to nurses across the unit (n = 23). Impacts of training on the confidence and competence of nurses to use such skills were investigated. Of nurses surveyed (n = 20), 80% wanted to use psychotherapeutic skills in routine practice, but only 35% had received training in such skills in the last 5 years. Focus group results identified that nurses wanted training in skills related to engaging patients, responding to resistance from patients, problem solving, reminiscence, relaxation, and cognitive behaviour therapy. Nurses who underwent the pilot training reported increases in confidence and competence in using such skills. These findings were replicated in the unit-wide training programme and were found to be durable across a 3-month follow-up period. This study highlighted the training needs of nurses working in an inpatient psychogeriatric setting, approaches to implementing new skills, and benefits of training for nurses' levels of confidence and competence in using psychotherapeutic skills.

RESUMEN

BACKGROUND: Exposure to radiation and/or chemotherapy during cancer treatment can compromise respiratory function. We investigated the risk of long-term respiratory mortality among 5-year cancer survivors diagnosed before age 40 years using the British Childhood Cancer Survivor Study (BCCSS) and Teenage and Young Adult Cancer Survivor Study (TYACSS). METHODS: The BCCSS comprises 34 489 cancer survivors diagnosed before 15 years from 1940 to 2006 in Great Britain. The TYACSS includes 200 945 cancer survivors diagnosed between 15 years and 39 years from 1971 to 2006 in England and Wales. Standardised mortality ratios and absolute excess risks were used. FINDINGS: Overall, 164 and 1079 respiratory deaths were observed in the BCCSS and TYACSS cohorts respectively, which was 6.8 (95% CI 5.8 to 7.9) and 1.7 (95% CI 1.6 to 1.8) times that expected, but the risks varied substantially by type of respiratory death. Greatest excess numbers of deaths were experienced after central nervous system (CNS) tumours in the BCCSS and after lung cancer, leukaemia, head and neck cancer and CNS tumours in the TYACSS. The excess number of respiratory deaths increased with increasing attained age, with seven (95% CI 2.4 to 11.3) excess deaths observed among those aged 50+ years in the BCCSS and three (95% CI 1.4 to 4.2) excess deaths observed among those aged 60+ years in the TYACSS. It was reassuring to see a decline in the excess number of respiratory deaths among those diagnosed more recently in both cohorts. CONCLUSIONS: Prior to this study, there was almost nothing known about the risks of respiratory death after cancer diagnosed in young adulthood, and this study addresses this gap. These new findings will be useful for both survivors and those involved in their clinical management and follow-up.
