Health-related quality of life and healthcare costs of symptoms and cardiovascular disease events in patients with atrial fibrillation: a longitudinal analysis of 27 countries from the EURObservational Research Programme on Atrial Fibrillation general long-term registry.

AIMS: We examine the effects of symptoms and cardiovascular disease (CVD) events on health-related quality of life (HRQOL) and healthcare costs in a European population with atrial fibrillation (AF). METHODS AND RESULTS: In the EURObservational Research Programme on AF long-term general registry, AF patients from 250 centres in 27 European countries were enrolled and followed for 2 years. We used fixed effects models to estimate the association of symptoms and CVD events on HRQOL and annual healthcare costs. We found significant decrements in HRQOL in AF patients in whom ST-segment elevation myocardial infarction (STEMI) [-0.075 (95% confidence interval -0.144, -0.006)], angina or non-ST-elevation myocardial infarction (NSTEMI) [-0.037 (-0.071, -0.003)], new-onset/worsening heart failure [-0.064 (-0.088, -0.039)], bleeding events [-0.031 (-0.059, -0.003)], thromboembolic events [-0.071 (-0.115, -0.027)], mild symptoms [0.037 (-0.048, -0.026)], or severe/disabling symptoms [-0.090 (-0.108, -0.072)] occurred during the follow-up. During follow-up, annual healthcare costs were associated with an increase of €11 718 (€8497, €14 939) in patients with STEMI, €5823 (€4757, €6889) in patients with angina/NSTEMI, €3689 (€3219, €4158) in patients with new-onset or worsening heart failure, €3792 (€3315, €4270) in patients with bleeding events, and €3182 (€2483, €3881) in patients with thromboembolic events, compared with AF patients without these events. Healthcare costs were primarily driven by inpatient costs. There were no significant differences in HRQOL or healthcare resource use between EU regions or by sex. CONCLUSION: Symptoms and CVD events are associated with a high burden on AF patients and healthcare systems throughout Europe.

Infection, delirium, and risk of dementia in patients with and without white matter disease on previous brain imaging: a population-based study.

BACKGROUND: The increased risk of dementia after delirium and infection might be influenced by cerebral white matter disease (WMD). In patients with transient ischaemic attack (TIA) and minor stroke, we assessed associations between hospital admissions with delirium and 5-year dementia risk and between admissions with infection and dementia risk, stratified by WMD severity (moderate or severe vs absent or mild) on baseline brain imaging. METHODS: We included patients with TIA and minor stroke (National Institutes of Health Stroke Score <3) from the Oxford Vascular Study (OXVASC), a longitudinal population-based study of the incidence and outcomes of acute vascular events in a population of 94 567 individuals, with no age restrictions, attending eight general practices in Oxfordshire, UK. Hospitalisation data were obtained through linkage to the Oxford Cognitive Comorbidity, Frailty, and Ageing Research Database-Electronic Patient Records (ORCHARD-EPR). Brain imaging was done using CT and MRI, and WMD was prospectively graded according to the age-related white matter changes (ARWMC) scale and categorised into absent, mild, moderate, or severe WMD. Delirium and infection were defined by ICD-10 coding supplemented by hand-searching of hospital records. Dementia was diagnosed using clinical or cognitive assessment, medical records, and death certificates. Associations between hospitalisation with delirium and hospitalisation with infection, and post-event dementia were assessed using time-varying Cox analysis with multivariable adjustment, and all models were stratified by WMD severity. FINDINGS: From April 1, 2002, to March 31, 2012, 1369 individuals were prospectively recruited into the study. Of 1369 patients (655 with TIA and 714 with minor stroke, mean age 72 [SD 13] years, 674 female and 695 male, and 364 with moderate or severe WMD), 209 (15%) developed dementia. Hospitalisation during follow-up occurred in 891 (65%) patients of whom 103 (12%) had at least one delirium episode and 236 (26%) had at least one infection episode. Hospitalisation without delirium or infection did not predict subsequent dementia (HR 1·01, 95% CI 0·86-1·20). In contrast, hospitalisation with delirium predicted subsequent dementia independently of infection in patients with and without WMD (2·64, 1·47-4·74; p=0·0013 vs 3·41, 1·91-6·09; p<0·0001) especially in those with unimpaired baseline cognition (cognitive test score above cutoff; 4·01, 2·23-7·19 vs 3·94, 1·95-7·93; both p≤0·0001). However, hospitalisation with infection only predicted dementia in those with moderate or severe WMD (1·75, 1·04-2·94 vs 0·68, 0·39-1·20; pdiff=0·023). INTERPRETATION: The increased risk of dementia after delirium is unrelated to the presence of WMD, whereas infection increases risk only in patients with WMD, suggesting differences in underlying mechanisms and in potential preventive strategies.

Improving sleep after stroke: A randomised controlled trial of digital cognitive behavioural therapy for insomnia.

Stroke is frequently accompanied by long-term sleep disruption. We therefore aimed to assess the efficacy of digital cognitive behavioural therapy for insomnia to improve sleep after stroke. A parallel group randomised controlled trial was conducted remotely in participant's homes/online. Randomisation was online with minimisation of between-group differences in age and baseline Sleep Condition Indicator-8 score. In total, 86 community-dwelling stroke survivors consented, of whom 84 completed baseline assessments (39 female, mean 5.5 years post-stroke, mean 59 years old), and were randomised to digital cognitive behavioural therapy or control (sleep hygiene information). Follow-up was at post-intervention (mean 75 days after baseline) and 8 weeks later. The primary outcome was self-reported insomnia symptoms, as per the Sleep Condition Indicator-8 (range 0-32, lower numbers indicate more severe insomnia, reliable change 7 points) at post-intervention. There were significant improvements in Sleep Condition Indicator-8 for digital cognitive behavioural therapy compared with control (intention-to-treat, digital cognitive behavioural therapy n = 48, control n = 36, 5 imputed datasets, effect of group p ≤ 0.02, η p 2 = 0.07-0.12 [medium size effect], pooled mean difference = -3.35). Additionally, secondary outcomes showed shorter self-reported sleep-onset latencies and better mood for the digital cognitive behavioural therapy group, but no significant differences for self-efficacy, quality of life or actigraphy-derived sleep parameters. Cost-effectiveness analysis found that digital cognitive behavioural therapy dominates over control (non-significant cost savings and higher quality-adjusted life years). No related serious adverse events were reported to the researchers. Overall, digital cognitive behavioural therapy for insomnia effectively improves sleep after stroke. Future research is needed to assess earlier stages post-stroke, with a longer follow-up period to determine whether it should be included as part of routine post-stroke care.

Cardiovascular disease burden due to productivity losses in European Society of Cardiology countries.

OBJECTIVE: Cardiovascular disease (CVD) is the leading cause of death across Europe. We estimated lost earnings (productivity losses) associated with premature mortality due to CVD, and separately for its main sub-categories of coronary heart disease and cerebrovascular disease, across 54 country members of the European Society of Cardiology (ESC). METHODS AND RESULTS: We used a standardized approach to estimate working years and earnings lost due to premature death resulting from CVD across the 54 ESC member countries in 2018. Our population-based approach was based on national data on the number of deaths, employment rates, and earnings by age group and sex. We discounted future working years and earnings lost to present values using a 3.5% annual rate. In 2018, there were 4.4 million deaths due to CVD across the 54 countries, with 7.1 million working years lost. This represented productivity losses due to premature death of €62 billion in 2018. Deaths due to coronary heart disease accounted for 47% (€29 billion) of all CVD costs, and cerebrovascular disease accounted for 18% (€11 billion). Approximately 60% (€37 billion) of all productivity losses occurred in the 28 European Union member states, despite accounting for only 42% (1.8 million) of deaths and 21% (1.5 million) of working years lost across the 54 countries. CONCLUSION: Our study provides a snapshot of the economic consequences posed by premature mortality due to CVD across 54 countries in 2018. The considerable variation across countries highlights the potential gains from policies targeting prevention and care of cardiovascular diseases.

Association of multimorbidity with mortality after stroke stratified by age, severity, etiology, and prior disability.

BACKGROUND: Multimorbidity is common in patients with stroke and is associated with increased medium- to long-term mortality, but its value for clinical decision-making and case-mix adjustment will depend on other factors, such as age, stroke severity, etiological subtype, prior disability, and vascular risk factors. AIMS: In the absence of previous studies, we related multimorbidity to long-term post-stroke mortality with stratification by these factors. METHODS: In patients ascertained in a population-based stroke incidence study (Oxford Vascular Study; 2002-2017), we related pre-stroke multimorbidity (weighted/unweighted Charlson comorbidity index (CCI)) to all-cause/vascular/non-vascular mortality (1/5/10 years) using regression models adjusted/stratified by age, sex, predicted early outcome (THRIVE score), stroke severity (NIH stroke scale (NIHSS)), etiology (Trial of Org 10172 in Acute Stroke Treatment (TOAST)), premorbid disability (modified Rankin Scale (mRS)), and non-CCI risk factors (hypertension, hyperlipidemia, atrial fibrillation, smoking, deprivation, anxiety/depression). RESULTS: Among 2454 stroke patients (M/SD age: 74.1/13.9 years; 48.9% male; M/SD NIHSS: 5.7/7.0), 1375/56.0% had ⩾ 1 CCI comorbidity and 685/27.9% had ⩾ 2. After age/sex adjustment, multimorbidity (unweighted CCI ⩾ 2 vs 0) predicted (all ps < 0.001) mortality at 1 year (aHR = 1.57, 95% CI = 1.38-1.78), 5 years (aHR = 1.73, 95% CI = 1.53-1.96), and 10 years (aHR = 1.79, 95% CI = 1.58-2.03). Although multimorbidity was independently associated with premorbid disability (mRS > 2: aOR = 2.76, 2.13-3.60) and non-CCI risk factors (hypertension: 1.56, 1.25-1.95; hyperlipidemia: 2.58, 2.03-3.28; atrial fibrillation: 2.31; 1.78-2.98; smoking: 1.37, 1.01-1.86), it predicted death after adjustment for all measured confounders (10-year-aHR = 1.56, 1.37-1.78, p < 0.001), driven mainly by non-vascular death (aHR = 1.89, 1.55-2.29). Predictive value for 10-year all-cause death was greatest in patients with lower expected early mortality: lower THRIVE score (pint < 0.001), age < 75 years (aHR = 2.27, 1.71-3.00), NIHSS < 5 (1.84, 1.53-2.21), and lacunar stroke (3.56, 2.14-5.91). Results were similar using the weighted CCI. CONCLUSION: Pre-stroke multimorbidity is highly prevalent and is an independent predictor of death after stroke, supporting its inclusion in case-mix adjustment models and in informing decision-making by patients, families, and carers. Prediction in younger patients and after minor stroke, particularly for non-vascular death, suggests potential clinical utility in targeting interventions that require survival for 5-10 years to achieve a favorable risk/benefit ratio.

NHS reference costs: a history and cautionary note.

Historically, the NHS did not routinely collect cost data, unlike many countries with private insurance markets. In 1998, for the first time the government mandated NHS trusts to submit estimates of their costs of service, known as reference costs. These have informed a wide range of health economic evaluations and important functions in the health service, such as setting prices.Reference costs are collected by progressively disaggregating budgets top-down into disease and treatment groups. Despite ongoing improvements to methods and guidance, these submissions continued to suffer a lack of accuracy and comparability, fundamentally undermining their credibility for critical functions.To overcome these issues, there was a long-held ambition to collect "patient-level" cost data. Patient-level costs are estimated with a combination of disaggregating budgets but also capturing the patient-level "causality of costs" bottom-up in the allocation of resources to patient episodes. These not only aim to capture more of the drivers of costs, but also improve consistency of reporting between providers.The change in methods may confer improvements to data quality, though judgement is still required and achieving consistency between trusts will take further work. Estimated costs may also change in important ways that may take many years to fully understand. We end on a cautionary note that patient-level cost methods may unlock potential, they alone contribute little to our understanding of the complexities involved with service quality or need, while that potential will require substantial investment to realise. Many healthcare resources cannot be attributed to individual patients so the very notion of "patient-level" costs may be misplaced. High hopes have been put in these new data, though much more work is now necessary to understand their quality, what they show and how their use will impact the system.

Economic burden of cardiovascular diseases in the European Union: a population-based cost study.

BACKGROUND AND AIMS: Cardiovascular disease (CVD) impacts significantly health and social care systems as well as society through premature mortality and disability, with patients requiring care from relatives. Previous pan-European estimates of the economic burden of CVD are now outdated. This study aims to provide novel, up-to-date evidence on the economic burden across the 27 European Union (EU) countries in 2021. METHODS: Aggregate country-specific resource use data on morbidity, mortality, and health, social and informal care were obtained from international sources, such as the Statistical Office of the European Communities, enhanced by data from the European Society of Cardiology Atlas programme and patient-level data from the Survey of Health, Ageing and Retirement in Europe. Country-specific unit costs were used, with cost estimates reported on a per capita basis, after adjustment for price differentials. RESULTS: CVD is estimated to cost the EU €282 billion annually, with health and long-term care accounting for €155 billion (55%), equalling 11% of EU-health expenditure. Productivity losses accounted for 17% (€48 billion), whereas informal care costs were €79 billion (28%). CVD represented a cost of €630 per person, ranging from €381 in Cyprus to €903 in Germany. Coronary heart disease accounted for 27% (€77 billion) and cerebrovascular diseases for 27% (€76 billion) of CVD costs. CONCLUSIONS: This study provides contemporary estimates of the wide-ranging impact of CVD on all aspects of the economy. The data help inform evidence-based policies to reduce the impact of CVD, promoting care access and better health outcomes and economic sustainability.

The randomised thoracoscopic talc poudrage+indwelling pleural catheters versus thoracoscopic talc poudrage only in malignant pleural effusion trial (TACTIC): study protocol for a randomised controlled trial.

INTRODUCTION: Malignant pleural effusion (MPE) is common, with 50 000 new cases per year in the UK. MPE causes disabling breathlessness and indicates advanced disease with a poor prognosis. Treatment approaches focus on symptom relief and optimising quality of life (QoL). Patients who newly present with MPE commonly require procedural intervention for both diagnosis and therapeutic benefit.Thoracoscopic pleural biopsies are highly sensitive in diagnosing pleural malignancy. Talc poudrage may be delivered at thoracoscopy (TTP) to prevent effusion recurrence by effecting pleurodesis. Indwelling pleural catheters (IPCs) offer an alternative strategy for fluid control, enabling outpatient management and are often used as 'rescue' therapy following pleurodesis failure or in cases of 'trapped lung'. It is unknown whether combining a TTP with IPC insertion will improve patient symptoms or reduce time spent in the hospital.The randomised thoracoscopic talc poudrage + indwelling pleural catheters versus thoracoscopic talc poudrage only in malignant pleural effusion trial (TACTIC) is the first randomised controlled trial (RCT) to examine the benefit of a combined TTP and IPC procedure, evaluating cost-effectiveness and patient-centred outcomes such as symptoms and QoL. The study remains in active recruitment and has the potential to radically transform the pathway for all patients presenting with MPE. METHODS AND ANALYSIS: TACTIC is an unblinded, multicentre, RCT comparing the combination of TTP with an IPC to TTP alone. Co-primary outcomes are time spent in the hospital and mean breathlessness score over 4 weeks postprocedure. The study will recruit 124 patients and aims to define the optimal pathway for patients presenting with symptomatic MPE. ETHICS AND DISSEMINATION: TACTIC is sponsored by North Bristol NHS Trust and has been granted ethical approval by the London-Brent Research Ethics Committee (REC ref: 21/LO/0495). Publication of results in a peer-reviewed journal and conference presentations are anticipated. TRIAL REGISTRATION: ISRCTN 11058680.

Epidemiology and clinical domains of Behçet's disease in the Cantabria region, Northern Spain.

OBJECTIVES: The prevalence of Behçet's disease (BD) has a considerable geographical and temporal variability. Data regarding epidemiology in Spain are limited. Our study aimed to assess the epidemiology and clinical domains of BD in a population-based cohort from Northern Spain and to compare the results with other geographical areas of other countries. METHODS: We conducted a cross-sectional study of a well-defined population in Northern Spain. Cases of suspected BD between January 1980 and December 2018 were identified. The diagnosis of BD was established according to the International Study Group (ISG) for Behçet's Disease. The incidence of BD between 1999 and 2018 was estimated by sex, age, and year of diagnosis. RESULTS: Of 120 patients with probable BD, 59 patients met ISG criteria and were finally included in the study, with a male/female ratio of 0.97; mean age 49.7±14.7 years. Incidence during the period of study was 0.492 per 100,000 people, observing an increase from January 1999 to December 2018. Prevalence was 10.14 per 100,000 inhabitants in 2018. Clinical manifestations were relapsing aphthous stomatitis (100%), genital ulcers (78%), skin involvement (84.7%), joint involvement (64.4%), uveitis (55.9%), central nervous system (16.9%), vascular (10.2%), and gastrointestinal manifestations (6.8%). CONCLUSIONS: The prevalence of BD in Cantabria is higher than in other Southern European countries. This difference may reflect a combination of geographic, genetic, or methodological variations, as well as the free accessibility to the Spanish Public Health System for the entire population. Clinical phenotypes observed are similar to those described in other world regions.

Relationship between patient functionality impairment and caregiver burden: is there a cut off point for the severe COPD patient?

BACKGROUND: Chronic obstructive pulmonary disease (COPD) patients experience a progressive limitation of their functionality accompanying their clinical evolution. Concretely, severe COPD patients usually require the figure of a caregiver. Caregiver burden has yet to be explored in other similar chronic diseases. The objective is to propose a cutoff point in different functional impairment aspects, to predict the presence of caregiver burden. METHODS: Severe COPD patients were divided into two groups according to the caregiver burden, measured with the Zarit Burden Interview (ZBI). The patients were assessed with the London Chest Activity of Daily Living (LCADL) scale, the Functional Independence Measure (FIM), and the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0). RESULTS: 70 COPD patients and their caregivers were included in this cross-sectional study. The ROC curve indicated a cutoff point of 19 in the LCADL scale (AUC = 0.722). Dependence in daily life activities had a cutoff point of 123 in the FIM (AUC = 0.776). Social participation in activities of daily living had a cutoff point of 37 in the WHODAS 2.0 (AUC = 0.739). CONCLUSION: Dyspnea related to functional status, dependence in daily life activities, and social participation in activities of daily living of severe COPD patients can predict caretaker burden.

Simultaneous and divergent evolution of resistance to cephalosporin/ß-lactamase inhibitor combinations and imipenem/relebactam following ceftazidime/avibactam treatment of MDR Pseudomonas aeruginosa infections.

OBJECTIVES: To describe and characterize the emergence of resistance to ceftolozane/tazobactam, ceftazidime/avibactam and imipenem/relebactam in a patient receiving ceftazidime/avibactam treatment for an MDR Pseudomonas aeruginosa CNS infection. METHODS: One baseline (PA1) and two post-exposure (PA2 and PA3) isolates obtained before and during treatment of a nosocomial P. aeruginosa meningoventriculitis were evaluated. MICs were determined by broth microdilution. Mutational changes were investigated through WGS. The impact on ß-lactam resistance of mutations in blaPDC and mexR was determined through cloning experiments and complementation assays. RESULTS: Isolate PA1 showed baseline resistance mutations in DacB (I354A) and OprD (N142fs) conferring resistance to conventional antipseudomonals but susceptibility to ceftazidime/avibactam, ceftolozane/tazobactam and imipenem/relebactam. Post-exposure isolates showed two divergent ceftazidime/avibactam-resistant phenotypes associated with distinctive mutations affecting the intrinsic P PDC ß-lactamase (S254Ins) (PA2: ceftolozane/tazobactam and ceftazidime/avibactam-resistant) or MexAB-OprM negative regulator MexR in combination with modification of PBP3 (PA3: ceftazidime/avibactam and imipenem/relebactam-relebactam-resistant). Cloning experiments demonstrated the role of PDC modification in resistance to ceftolozane/tazobactam and ceftazidime/avibactam. Complementation with a functional copy of the mexR gene in isolate PA3 restored imipenem/relebactam susceptibility. CONCLUSIONS: We demonstrated how P. aeruginosa may simultaneously develop resistance and compromise the activity of new ß-lactam/ß-lactamase inhibitor combinations when exposed to ceftazidime/avibactam through selection of mutations leading to PDC modification and up-regulation of MexAB-OprM-mediated efflux.

Comparison of the 22nd World Health Organization Model List of Essential Medicines with the explicit criteria for the treatment of chronicity in elderly patients.

OBJECTIVES: This study analysed whether the Model List of Essential Medicines is suitable for elderly patients. Furthermore, it investigated the specific issues that should be considered when prescribing a drug and which drugs should be added to improve the list according to the explicit criteria guidelines. METHODS: A qualitative descriptive review was performed comparing the explicit criteria guidelines of Beers 2019, Laroche, McLeod, NORGEP, PRISCUS, STOPP/START 2014 and Winit-Watjana with the 22nd edition of the Model List of Essential Medicines. RESULTS: The Model List of Essential Medicines has 458 drugs. Depending on the explicit criteria considered, there were different numbers of potentially inappropriate medications and potential prescribing omissions. When all explicit criteria were combined, a total of 73 medicines were classified as potentially inappropriate. Using the STOPP/START criteria, 46 potential prescribing omissions were detected. According to these explicit criteria, the Model List of Essential Medicines appeared to lack some medicines. CONCLUSIONS: Explicit criteria guidelines have different potential for detecting potentially inappropriate medications. Our findings suggest that some drugs should be added to the next edition of the Model List of Essential Medicines to cover some therapeutic gaps.

Systemic treatment in sarcoidosis: Experience over two decades.

OBJECTIVE: The aim of this study was to evaluate the frequency of systemic treatment in a cohort of sarcoidosis patients and identify presenting clinical features as predictive factors of the need for systemic immunosuppressive therapy. METHODS: Retrospective study of 342 patients diagnosed and followed-up from January 1999 to December 2019 in a University Hospital in Northern Spain. The diagnosis of sarcoidosis was established according to ATS/ERS/WASOG criteria. A comparative analysis was performed between treated and untreated patients. Predictive factors of treatment prescription according to initial clinical manifestations were identified (multivariate analysis). RESULTS: Mean age at diagnosis was 47.7±15.1 years, with a slight female predominance (51.8%) and Caucasian majority (94.2%). The main clinical manifestation was thoracic involvement (88.3%). Extrathoracic manifestations were detected in 68.4% cases, mainly cutaneous (34.2%), articular (27.8%) and ocular (17.8%). A total of 207 (60.5%) patients required systemic treatment. Glucocorticoid therapy was the most widely used (60.5%). Conventional immunosuppressive therapy in 25.4%, more frequently MTX (21.9%). Biologic therapy was prescribed in 12.9%, especially adalimumab (9.1%). Male gender (OR: 1.65; 95%CI: 1.06-2.56), intrathoracic (OR: 2.41; 95%CI: 1.22-4.76), ocular (OR: 4.14; 95%CI: 2.01-8.52), parotid (OR: 1.60; 95%CI: 1.39-1.94), neurological (OR: 5.00; 95%CI: 1.68-14.84), and renal (OR: 1.59; 95%CI: 1.38-1.94) involvement were identified as risk factors associated with the need of systemic treatment. CONCLUSION: Most patients (60.5%) of sarcoidosis in our series required systemic therapy. An association between certain characteristics at initial presentation (male gender, lung, ocular, parotid, neurological and renal involvement) and the need of systemic treatment was identified.

Non-invasive sensor methods used in monitoring newborn babies after birth, a clinical perspective.

BACKGROUND: Reducing the global new-born mortality is a paramount challenge for humanity. There are approximately 786,323 live births in the UK each year according to the office for National Statistics; around 10% of these newborn infants require assistance during this transition after birth. Each year around, globally around 2.5 million newborns die within their first month. The main causes are complications due to prematurity and during delivery. To act in a timely manner and prevent further damage, health professionals should rely on accurate monitoring of the main vital signs heart rate and respiratory rate. AIMS: To present a clinical perspective on innovative, non-invasive methods to monitor heart rate and respiratory rate in babies highlighting their advantages and limitations in comparison with well-established methods. METHODS: Using the data collected in our recently published systematic review we highlight the barriers and facilitators for the novel sensor devices in obtaining reliable heart rate measurements. Details about difficulties related to the application of sensors and interfaces, time to display, and user feedback are explored. We also provide a unique overview of using a non-invasive respiratory rate monitoring method by extracting RR from the pulse oximetry trace of newborn babies. RESULTS: Novel sensors to monitor heart rate offer the advantages of minimally obtrusive technologies but have limitations due to movement artefact, bad sensor coupling, intermittent measurement, and poor-quality recordings compared to gold standard well established methods. Respiratory rate can be derived accurately from pleth recordings in infants. CONCLUSION: Some limitations have been identified in current methods to monitor heart rate and respiratory rate in newborn babies. Novel minimally invasive sensors have advantages that may help clinical practice. Further research studies are needed to assess whether they are sufficiently accurate, practical, and reliable to be suitable for clinical use.

Cost-effectiveness of ambulatory care management of primary spontaneous pneumothorax: an open-label, randomised controlled trial.

BACKGROUND: Ambulatory management of primary spontaneous pneumothorax has been shown to reduce initial hospitalisation, but at the expense of increase adverse events. As a result, questions remain about the cost-effectiveness of this option. OBJECTIVES: A within-trial economic evaluation alongside a randomised controlled trial was performed to assess the cost-effectiveness of ambulatory care when compared with standard guideline-based management. METHODS: Patients were randomly assigned to treatment with either an ambulatory device or standard guideline-based management (aspiration, standard chest tube insertion or both). Follow-up was 12 months. Outcomes included healthcare resource use and costs, quality of life, quality-adjusted life-years (QALYs) and cost-effectiveness. RESULTS: 236 patients were recruited and randomly assigned to ambulatory care (n=117) and standard care (n=119). After multiple imputation for missing data, patients in the ambulatory care group had significantly lower National Health Service healthcare costs (-£788, 95% CI difference: -1527 to -50; p=0.037) than those in the standard care group. There were no differences in the number of QALYs gained (mean difference: -0.001, 95% CI difference: -0.032 to 0.030; p=0.95). When standard care was compared with ambulatory care, the incremental cost-effectiveness ratio was £799 066 per QALY gained, well above current thresholds of cost-effectiveness. As a result, the probability of ambulatory care being cost-effective was 0.93. CONCLUSION: Outpatient ambulatory management is highly likely to be a cost-effective option in the management of primary pneumothorax. TRIAL REGISTRATION NUMBER: ISRCTN79151659.

Cost-effectiveness of home-based stroke rehabilitation across Europe: A modelling study.

The aim of this study was to explore the cost-effectiveness of home-based versus centre-based rehabilitation in stroke patients across Europe. A state-transition cohort model was developed to simulate the impact of the intervention in 32 European countries. A cost-utility analysis was conducted from a societal perspective including healthcare, social care and informal care costs, and productivity losses. Health outcomes were expressed as QALYs. Sensitivity analyses were conducted concerning model input values and structural assumptions. Data were obtained from a population-based cohort and previously published studies. Across Europe, over 855,000 patients with stroke would be eligible for rehabilitation in 2017. Europe-wide implementation of home-based rehabilitation was estimated to produce 61,888 additional QALYs (95% CI: 3,609 to 118,679) and cost savings of €237 million (95% CI: -237 to 1,764) and of €352 million (95% CI: -340 to 2,237) in health- and social-care and societal costs, respectively. Under base case assumptions, home-based rehabilitation was found highly likely to be cost-effective (>90%), compared to centre-based rehabilitation, in most European countries (29 out of 32). Evidence from this study suggests that a shift from a centre-based to a home-based approach to stroke rehabilitation is likely to be good value for money in most European countries. Further research should be conducted to assess the generalisability of these findings to local settings.
