Evaluation of the 'Live Life Better Service', a community-based weight management service, for morbidly obese patients.

BACKGROUND: There is a limited evidence on the effectiveness of lifestyle interventions in achieving and maintaining a significant level of weight loss in morbidly obese patients. This study evaluated the impact on weight loss and psychological well-being of a community-based weight management service for morbidly obese patients [body mass index (BMI) ≥35 with related co-morbidities or BMI >40] in Derbyshire county. METHODS: Five hundred and fifty-one participants entered the service since 2010, and 238 participants were still active within the service or had completed the 2-year intervention in April 2013. A one-group pre-post design was used to determine average weight loss (kg) and impact on mental health and well-being [using the validated clinical outcomes of routine evaluation-outcome measure (CORE-OM) questionnaire] among participants. Measurements were recorded at baseline, 12 weeks, 24 weeks, 1 year, 18 months and 2 years, and significance (P ≤ 0.05) was determined using the paired sample t-test. RESULTS: Statistically significant weight loss was recorded at each measurement point for those participants who remained engaged with the service (4.9 kg weight loss at 12 weeks to 18.2 kg at 2 years). There was a significant positive impact on psychological well-being demonstrated by CORE-OM score. CONCLUSIONS: Findings show clinically and statistically significant weight loss among participants with improvements in physical and mental health.

A prospective observational study to investigate the association between abnormal hand movements and delirium in hospitalised older people.

OBJECTIVE: to examine the relationship between carphology (aimlessly picking at bedclothes), floccillation (plucking at the air) and delirium in older patients admitted to specialist elderly care wards. DESIGN: daily observation for behaviours of carphology and floccillation embedded within a 'before' and 'after' study. SETTING: three specialist elderly care wards in a general hospital. SUBJECTS: older people admitted to hospital as emergencies. METHODS: patients recruited into a delirium prevention study were observed daily for delirium using the confusion assessment method (CAM). Occurrences of carphology and/or floccillation were also recorded. Sensitivity, specificity and positive and negative predictive values for carphology/floccillation for the diagnosis of delirium were calculated. Inpatient mortality rates were compared for patients who did, and did not exhibit features of carphology and/or floccillation. RESULTS: four hundred and thirty-seven patients were recruited into the study. One hundred and ten participants experienced an episode of delirium, 21 exhibited behaviours of carphology and/or floccillation. The sensitivity and specificity of carphology and/or floccillation for the diagnosis of delirium were 14 and 98%, respectively; positive likelihood ratio 6.8. Carphology and floccillation were associated with both hyper- and hypo-active delirium subtypes, and occurred early during incident delirium (67% within 2 days of delirium onset). The inpatient mortality rate in patients with carphology/floccillation was double the rate in patients without the behaviours (23.8 versus 11.2%, Fisher's exact test P = 0.16). CONCLUSIONS: carphology and floccillation are uncommon physical signs, but their presence is highly suggestive of delirium. The behaviours are unrelated to delirium subtype making their presence particularly useful in the diagnosis of hypo-active delirium.

History of a suspected delirium is more common in dementia with Lewy bodies than Alzheimer's disease: a retrospective study.

BACKGROUND: Delirium is common and is associated with an increased risk of dementia. However, it is not clear whether delirium confers increased risk of any particular type of dementia. We performed a retrospective study of Alzheimer's disease (AD) and Dementia with Lewy bodies (DLB) to ascertain whether a suspected episode of preceding delirium was more common prior to diagnosis in either type of dementia. METHODS: The study was carried out in a tertiary referral unit for the diagnosis of dementia. Clinic letters from the first presentation to the unit of 85 cases with DLB and 95 cases of AD were reviewed for documentation of any previous episodes of suspected delirium. RESULTS: In this study, 25% of DLB cases had at least one reported episode of suspected delirium as compared to 7% of AD cases (p = 0.001). For the DLB cases who had a prior suspected delirium, 23% had more than one episode compared with 14% of the AD group. The median time between most recent suspected episode of delirium and diagnosis of dementia in both groups was less than a year CONCLUSIONS: A greater proportion of those presenting and diagnosed with DLB had a documentation of a suspected delirium than those diagnosed with AD. Delirium may lead to a higher risk of DLB as opposed to other forms of dementia, or delirium may, at least in some cases, represent the early stages of DLB. These data suggest that a diagnosis of DLB should be specifically considered in those presenting with a delirium.

Interventions for preventing delirium in older people in institutional long-term care.

BACKGROUND: Delirium is a common and distressing complication of a range of stressor events including infection, new medications and environment change that is often experienced by older people with frailty and dementia. Older people living in institutional long-term care (LTC)are at high risk of delirium, which increases the risk of admission to hospital, development of or worsening of dementia, and mortality.Delirium is also associated with substantial healthcare costs. Although it is possible to prevent delirium in the hospital setting by providing multicomponent delirium prevention interventions it is currently unclear whether interventions to prevent delirium in LTCare effective. OBJECTIVES: To assess the effectiveness of interventions for preventing delirium in older people in long term care. SEARCH METHODS: We searched ALOIS (www.medicine.ox.ac.uk/alois) - the Cochrane Dementia and Cognitive Improvement Group's Specialised Register- on 23 April 2013. The search was as sensitive as possible to identify all studies on ALOIS relating to delirium. We ran additional separate searches in major healthcare databases, trial registers, the Cochrane Central Register of Controlled Trials (CENTRAL) and grey literature sources, to ensure that the search was as comprehensive as possible. SELECTION CRITERIA: We included randomised controlled trials (RCTs) and cluster-randomised controlled trials (cluster-RCTs) of single- and multi componentn on-pharmacological and pharmacological interventions for preventing delirium in older people (aged 65 years and over) in permanent LTC residence. DATA COLLECTION AND ANALYSIS: Two independent review authors examined the titles and abstracts of citations identified by the search for eligibility and extracted data, with any disagreements settled by consensus. Primary outcomes were prevalence, incidence and severity of delirium. Secondary outcomes included new diagnosis of dementia, activities of daily living, quality of life and adverse outcomes. We used risk ratios (RRs)as measures of treatment effect for dichotomous outcomes and hazard ratios (HR) for time to event data.Main results We included two trials that recruited 3636 participants.Both were complex single-component non-pharmacological delirium prevention interventions. Risk of bias for many items was unclear due to inadequate reporting. Notably, there was no evidence of blinding of trial participants or assessors in either trial. One small cluster-RCT (n = 98) of a hydration-based intervention reported no reduction in delirium incidence in the intervention group compared to control (RR 0.85, 95% confidence interval (CI) 0.18 to 4.00, analysis not adjusted for clustering, very low quality evidence). Results were imprecise and there were serious limitations evident in trial design.One large cluster-RCT (n = 3538) of a computerised system to identify medications that may contribute to delirium risk and trigger a pharmacist-led medication review reported a large reduction in delirium incidence (12-month HR 0.42, CI 0.34 to 0.51, moderat equality evidence) but no clear evidence of reduction in hospital admissions (HR 0.89, CI 0.72 to 1.10, moderate quality evidence), in mortality (HR 0.88, CI 0.66 to 1.17, moderate quality evidence) or in falls risk (HR 1.03, CI 0.92 to 1.15, moderate quality evidence).Authors' conclusions Our review identified very limited evidence on interventions for preventing deliriumin older people in LTC. Introduction of a software based intervention to identify medications that could contribute to delirium risk so that a pharmacist-led medication review and monitoring plan can be initiated may reduce incidence of delirium for older people in institutional LTC. This is based on one large RCT in the United States and may not be practical in other countries which do not have comparable information technology services available in care homes. Our review identified only one ongoing pilot trial of a multicomponent delirium prevention intervention and no trials of pharmacological agents. Future trials of computerised medication management systems and multicomponent non-pharmacological and pharmacological delirium prevention interventions for older people in LTC are needed to help inform the provision of evidence based care for this vulnerable group.

Effectiveness of a multi-component intervention to reduce delirium incidence in elderly care wards.

OBJECTIVE: to examine the effect of a multi-component, delirium prevention intervention on rates of incident delirium for patients admitted to specialist elderly care wards. DESIGN: 'before' and 'after' study. SETTING: three specialist elderly care wards in a general hospital. SUBJECTS: older people admitted as emergencies. METHODS: a multi-component delirium prevention intervention that targeted delirium risk factors was implemented by clinical staff. Demographic information and assessments for delirium risk factors were recorded by research staff within 24 h of admission to the ward. New onset (incident) delirium was diagnosed by daily research staff assessments using the Confusion Assessment Method and Delirium Rating Scale-Revised-98. RESULTS: a total of 436 patients were recruited (249 in the 'before' and 187 in the 'after' group). Incident delirium was significantly reduced ('before' = 13.3%; 'after' = 4.6%; P = 0.006). Delirium severity and duration were significantly reduced in the 'after' group. Mortality, length of stay, activities of daily living score at discharge and new discharge to residential or nursing home rates were similar for both groups. CONCLUSIONS: a multi-component, delirium prevention intervention directed at delirium risk factors and implemented by local clinical staff can reduce incident delirium on specialist elderly care wards.

Breast-Q sensory outcomes of non-neurotized, autologous, unilateral breast reconstruction with a minimum of 3-year follow-up.

INTRODUCTION: Sensory reinnervation of autologous breast tissue after free flap reconstruction is highly variable. There is no long-term follow-up data exploring spontaneous reinnervation and how this affects patients' quality of life nor the nerve-related symptoms they experience. To address this issue, we invited patients with a minimum of 3 years after non-neurotized, free flap breast reconstruction to complete patient-reported outcome measures exploring sensation, quality of life and breast-related symptoms. METHODS: We performed a retrospective cohort study of patients undergoing unilateral Muscle-Sparing Transverse Rectus Abdominus Muscle (MS-TRAM) or deep inferior epigastric artery perforator (DIEP) flap breast reconstruction between 01-01-2015 and 31-12-2019 in the Department of Plastic and Reconstructive Surgery at Manchester University NHS Foundation Trust. We invited participants to complete the recently developed Breast-Q© Breast Sensation Module. RESULTS: All patients had undergone unilateral immediate (n = 85) or delayed (n = 82) breast reconstruction after mastectomy using either a free DIEP (n = 150) or TRAM (n = 17) flap reconstruction a minimum of 3 years prior. The median age at operation was 48. Sensation after reconstruction was significantly reduced in the reconstructed breast compared with the contralateral breast (P < 0.0001) with a reduction in reported quality of life (immediate (68.0 [54.0, 89.0]) and delayed (68.0 [62.0, 83.8])). The sensation was significantly better in immediate vs delayed procedures (P = 0.024). Sensory scores after reconstruction increased with age (P = 0.036). DISCUSSION: Breast sensation after non-neurotized reconstruction with autologous tissue is significantly reduced at long-term follow-up with a reduction in quality of life. A minimum outcome set for quantification of breast sensation is required and future research into the cost-benefit of neurotized, autologous breast reconstruction is needed.

Using consensus methods to prioritize modifiable risk factors for development of manifestations of frailty in hospitalized older adults.

AIM: The aim of the study was to reach consensus on modifiable risk factors for a novel system of care to address Manifestations of Frailty in hospitalized older adults. DESIGN: Consensus study. METHOD: A modified nominal group technique, incorporating expert group face-to-face interaction, review of existing evidence and pre/post-meeting questionnaire completion was undertaken November 2019-February 2020. RESULTS: Seventy-one risk factors, within seven risk factor domains (pain, medication, fluid and nutrition intake, mobility, elimination, infection, additional patient factors) were considered. It was agreed that 44 risk factors incorporating patient, organizational and environmental risk factors were modifiable and should be included in a novel system of care.

A UK consensus statement on thromboprophylaxis for autologous breast reconstruction.

Microsurgical breast reconstruction accounts for 22% of breast reconstructions in the UK. Despite thromboprophylaxis, venous thromboembolism (VTE) occurs in up to 4% of cases. Using a Delphi process, this study established a UK consensus on VTE prophylaxis strategy, for patients undergoing autologous breast reconstruction using free-tissue transfer. It captured geographically divergent views, producing a guide that reflected the peer opinion and current evidence base. METHODS: Consensus was ascertained using a structured Delphi process. A specialist from each of the UK's 12 regions was invited to the expert panel. Commitment to three to four rounds of questions was sought at enrollment. Surveys were distributed electronically. An initial qualitative free-text survey was distributed to identify likely lines of consensus and dissensus. Each panelist was provided with full-text versions of key papers on the topic. Initial free-text responses were analyzed to develop a set of structured quantitative statements, which were refined via a second survey as a consensus was approached. RESULTS: The panel comprised 18 specialists: plastic surgeons and thrombosis experts from across the UK. Each specialist completed three rounds of surveys. Together, these plastic surgeons reported having performed more than 570 microsurgical breast reconstructions in the UK in 2019. A consensus was reached on 27 statements, detailing the assessment and delivery of VTE prophylaxis. CONCLUSION: To our knowledge, this is the first study to collate current practice, expert opinion from across the UK, and a literature review. The output was a practical guide for VTE prophylaxis for microsurgical breast reconstruction in any UK microsurgical breast reconstruction unit.

Health-related outcomes in patients enrolled on surgical and non-surgical routes in a weight management service.

BACKGROUND AND AIMS: This study evaluates a specialist weight management service and compares outcomes in participants referred to the service undergoing either surgery or non-surgical routes to support weight loss. METHODS: Four hundred and forty eight participants were assessed on various weight-related outcomes (body mass index [BMI], psychological distress, quality of life, nutrition, weight-related symptoms, physical activity) on referral to the service and on discharge. The effect of group (surgery or non-surgery) and time in the service were facilitated by doubly multivariate analyses of variance models. RESULTS: Between referral and discharge, participants improved significantly on a combination of outcomes (P < .001) and on each outcome assessed individually. The magnitude of overall improvement was moderate (partial-η2 = 0.141). Individual improvement components varied; including a moderate reduction of 3.2% in the BMI outcome measure and a substantive gain of 64.6% in quality of life. Participants on non-surgical routes performed significantly better than participants on surgical routes on a linear combination of outcomes (P < .001) and on all outcomes except nutrition; with an effect of route small-to-moderate in magnitude (partial-η2 = 0.090). CONCLUSIONS: Weight management services are successful in achieving weight management-related outcomes in the short- and long-term, with large overall improvements between referral and discharge averaged over all participants observed. Non-surgical routes appear to confer benefits between referral and discharge compared to surgical routes.

Stop Delirium! A complex intervention to prevent delirium in care homes: a mixed-methods feasibility study.

BACKGROUND: delirium is likely to be particularly common in care homes, given the clustering of known risk factors in these settings. Preventing delirium should result in significant benefits, including better quality of care and improved outcomes for residents. OBJECTIVE: to test the feasibility of 'Stop Delirium!', an intervention to prevent delirium in care homes for older people, and to optimise parameters to inform the design of a future trial evaluation. METHOD: we delivered Stop Delirium! to six care homes over 10 months, in a mixed methods before and after study. RESULTS: Stop Delirium! was successfully implemented in the study homes. We found evidence supporting positive changes in staff attitudes and practice after the intervention. Although qualitative data suggested it was too early to expect changes in resident outcomes, we also found preliminary evidence suggesting potential improvements in a range of outcomes, including a reduction in the number of falls and prescribed medications. CONCLUSION: a complex intervention for delirium prevention in care homes is feasible and has the potential to improve staff practice and outcomes for residents. This work provides the basis for the next phase of the evaluation to establish its effectiveness and cost-effectiveness.

Health psychology attendance: A multilevel analysis of patient-level predictors and therapist effects.

The study investigated adult outpatient Health Psychology Services appointment attendance, cancellation, and missed appointments (A/C/M). The first objective was to determine which demographic and process factors predicted the probability of A/C/M. The second objective was to determine whether there remained residual significant differences in A/C/M between therapists (i.e., a "therapist effect"), after controlling for explanatory variables. We conducted a practice-based retrospective 2-year cohort study. Three-level multilevel models were constructed and tested to analyze the probability of A/C/M at (1) assessment appointments (N = 1,175) and (2) follow-up appointments (N = 5,441). After controlling for predictor variables, significant therapist effects were found for attendance (10.0% to 13.0%) and cancellation (4.4%) at follow-up appointments (but not assessments), indicating significantly different attendance rates at follow-up between therapists. Predictors of attendance at follow-up included patient age, pretherapy symptom severity scores (including risk and symptom scores), and completion of intake questionnaires. Early morning follow-up appointments were least likely to be canceled, followed by late afternoon and finally midday appointments. Treatment intensity predicted attendance, but among qualified therapists, qualification type and pay level were nonsignificant. No significant predictors of attendance at assessment were detected. Attendance at Health Psychology Services outpatient appointments varies significantly according to patient, therapist, and appointment factors. Key routinely collected variables are predictive of attendance at follow-up. Clinical implications include the potential to identify patients at risk of nonattendance and target engagement interventions to these patients. Research directions include closer examination of variability in follow-up attendance between therapists. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

The ethics of consent in delirium studies.

BACKGROUND: Delirium is a syndrome of acute, fluctuating confusion, which affects older people who are unwell. Although common and associated with significant poor outcomes, little is known about its pathophysiology, prevention, or treatment. Delirium research could potentially deliver important benefits for patients and is urgently required. However, such research is challenging as it inevitably involves the recruitment of patients who have impaired capacity to consent, due to the nature of delirium itself and the fact that it is people with dementia or severe illness who are most at risk. AIM: This article explores the ethical tensions inherent in the need to protect vulnerable participants in delirium research and the urgent need for high-quality research in a neglected condition. CONCLUSIONS: The current research regulations are unnecessarily stringent and may impede good-quality delirium research. There is in particular the danger that they lead to the recruitment of unrepresentative study populations. We suggest a number of changes to the regulations, such as extending the use of the existing European Union procedures for registered medical practitioner proxy consent. We invite comments and feedback from the research community.

PICO™ incision closure in oncoplastic breast surgery: a case series.

Single-use negative pressure wound therapy (PICO™) has been used on high-risk surgically incised wounds with encouraging results, but there is no evidence for its use in oncoplastic breast surgery. This article reports a case series with closed incisions in oncoplastic breast procedures following the introduction of PICO™.

Pilot trial of Stop Delirium! (PiTStop)--a complex intervention to prevent delirium in care homes for older people: study protocol for a cluster randomised controlled trial.

BACKGROUND: Delirium (or acute confusion) is a serious illness common in older people, in which a person's thinking and perceptions may be affected. Reducing delirium is important because of the considerable distress it causes, and the poor outcomes associated with it, such as increased admissions to hospital, falls, mortality and costs to the National Health Service (NHS). Preventing delirium is possible using multicomponent interventions; successful interventions in hospitals have reduced it by one-third. However, there is little research to guide practice in care homes, where it is common because of the clustering of known risk factors (older age, frailty, and dementia). In previous work we developed a multicomponent intervention to prevent delirium in care homes, called Stop Delirium! The intervention was based upon evidence from the research literature relating to the prevention of delirium and on strategies to change professional practice. Before starting a large costly trial of Stop Delirium!, this pilot study will test and help improve the design and feasibility of the trial protocol. METHODS/DESIGN: We plan to conduct a cluster randomised pilot trial in 14 care homes (independent residential and nursing). Following recruitment of residents (over 60 years, consenting or with consultee agreement, able to communicate in English, and not in palliative care) participating homes will be randomised, stratified by size of home and proportion of residents with dementia. Stop Delirium! will be delivered to intervention homes over 16 months, with controls receiving usual care. The primary outcome measure will be the presence of delirium on any day during a one-month post-intervention period.We will collect data to determine 1) recruitment and attrition rates, 2) feasibility of various outcomes measurements, and 3) feasibility of capturing health resource use (resident diaries and by examining health records). We will estimate the between-cluster variation for the primary outcome, delirium occurrence. DISCUSSION: This pilot study will refine methods for the definitive trial. The lessons learnt will also contribute to implementing National Institute for Health and Clinical Excellence (NICE) delirium guidelines, which recommend multicomponent interventions for delirium prevention.

Subfascial harvest of the extended latissimus dorsi myocutaneous flap in breast reconstruction: a comparative analysis of two techniques.

BACKGROUND: Widespread adoption of the extended latissimus dorsi myocutaneous flap in breast reconstruction has been limited by donor-site complications. The dissection plane may be either above or below the superficial layer of the thoracolumbar fascia, which may be transferred with the flap or retained on the back skin flaps. The aim of this study was to investigate whether varying the plane of dissection improves donor-site morbidity and complications. METHODS: A comparative analysis of consecutive women treated with extended latissimus dorsi myocutaneous breast reconstruction by a single surgeon (D.F.) between 2006 and 2012 was performed. RESULTS: Eighty patients were reviewed. Between 2006 and 2011, 47 patients were treated with traditional suprafascial harvest (group A); the subsequent 33 patients between 2011 and 2012 had subfascial harvest (group B), retaining the superficial fascia on the back skin flaps. When compared with group A, group B patients showed significant reduction in both mean number of seroma drainage events (p = 0.027) and mean total aspirated seroma volume, which was reduced by half (p = 0.006). Group B patients also reported significant reduction in donor-site pain (p = 0.041) and donor-site scar adherence to the chest wall (p = 0.026). No increases in flap or donor-site dehiscence, partial flap loss, or other minor or major complications were observed. CONCLUSION: The technique of subfascial harvest during autologous latissimus dorsi flap breast reconstruction significantly improves back donor-site morbidity without compromising flap survival. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

How well are we managing diabetes in long-term care?

The care received by nursing home residents with diabetes does not meet ADA standards for ambulatory adults, this study finds. Nor should it. The frail elderly need new standards that address their particular needs.

An incidental right atrial mass: cavernous hemangioma.

Cardiac hemangiomas are rare benign tumors of the heart typically diagnosed incidentally. We report a case of a 70-year-old man with a right atrial cavernous hemangioma and a concomitant pulmonary embolism. The possible association, clinical features, operative procedure, and pathologic findings are described.

Diabetes care in extended-care facilities: appropriate intensity of care?

OBJECTIVE: The American Diabetes Association (ADA) does not recognize different treatment goals for the institutionalized adult compared with the outpatient adult with diabetes, nor has it outlined specific recommendations for this population. The purpose of this study was to examine physician management of patients with type 1 and type 2 diabetes residing in extended-care facilities and to compare this management with ADA standards of care for the outpatient adult. RESEARCH DESIGN AND METHODS: This retrospective chart review included data from 108 residents with type 1 or type 2 diabetes at 11 extended health care facilities in the Midwestern U.S. and included a review of the medical problem list, medication list, laboratory reports, and all physician and consultation notes during the study period. RESULTS: Blood glucose was monitored in 98% of the subjects, and 38% met glucose goals. A1C goal was achieved in 67% of patients. Blood pressure was monitored in 94% of patients, with 55% meeting goal. Thirty-one percent of patients had yearly lipids checked, 37% had annual electrocardiograms, 7% had urine analyzed for microalbuminuria, 42% were on aspirin, 87% received foot exams, 42% received dilated eye exams, 89% received influenza vaccinations, and 46% received pneumoccocal vaccinations. CONCLUSIONS: Care of the institutionalized elderly with diabetes fails to meet ADA standards of care for the outpatient adult. Separate practice guidelines are needed for people with diabetes who reside in extended care facilities in order to improve quality and consistency of care.
