ABSTRACT

Multiple Criteria Decision Analysis (MCDA) has emerged as a methodology for Health Technology Assessment (HTA). However, limited empirical evidence is available on its use by decision-makers; where available, it only comes from single-setting exercises, while cross-country comparative studies are unavailable. This study applies the Advance Value Framework (AVF), an MCDA methodology for HTA based on multi-attribute value theory, through a series of case studies with decision-makers in four countries, to explore its feasibility and compare decision-makers' value preferences and results. The AVF was applied in the evaluation of three drugs for metastatic, castrate resistant, prostate cancer (abiraterone, cabazitaxel and enzalutamide) in the post-chemotherapy indication. Decision conferences were organised in four European countries in collaboration with their HTA or health insurance organisations by involving relevant assessors and experts: Sweden (TLV), Andalusia/Spain (AETSA), Poland (AOTMiT) and Belgium (INAMI-RIZIV). Participants' value preferences, including performance scoring and criteria weighting, were elicited through a facilitated decision-analysis modelling approach using the MACBETH technique. Between 6 and 11 criteria were included in each jurisdiction's value model, allocated across four criteria domains; Therapeutic Benefit criteria consistently ranked first in relative importance across all countries. Consistent drug rankings were observed in all settings, with enzalutamide generating the highest overall weighted preference value (WPV) score, followed by abiraterone and cabazitaxel. Dividing drugs' overall WPV scores by their costs produced the lowest "cost per unit of value" for enzalutamide, followed by abiraterone and cabazitaxel. These results come in contrast with the actual country HTA recommendations and pricing decisions. Overall, although some differences in value preferences were observed between countries, drug rankings remained the same. The MCDA methodology employed could act as a decision support tool in HTA, due to the transparency in the construction of value preferences in a collaborative manner.

ABSTRACT

BACKGROUND: Innovative care models such as public-private partnerships (PPPs) may help meet the challenge of providing cost-effective high-quality care for the steadily growing and complex chronic kidney disease population since they combine the expertise and efficiency of a specialized dialysis provider with the population care approach of a public entity. We report the five-years main clinical outcomes of a population of patients treated on hemodialysis within a PPP-care model in Italy. METHODS: This descriptive retrospective cohort study consisted of all consecutive hemodialysis patients treated in the NephroCare-operated Nephrology and Dialysis unit of the Seriate Hospital in 2012-2016, which exercises a PPP-care model. Clinical and treatment information was obtained from the European Clinical Database. Hospitalization outcomes and cumulative all-cause mortality incidences that accounted for competing risks were calculated. RESULTS: We included 401 hemodialysis patients (197 prevalent and 204 incident patients) in our study. The mean cohort age and age-adjusted Charlson Comorbidity Index were 67.0 years and 6.7, respectively. Patients were treated with online high-volume hemodiafiltration or high-flux hemodialysis. Parameters of treatment efficiency were above the recommended targets throughout the study period. Patients in the PPP experienced benefits in terms of hospitalization (average number of hospital admissions/patient-year: 0.79 and 1.13 for prevalent and incident patients, respectively; average length of hospitalization: 8.9 days for both groups) and had low cumulative all-cause mortality rates (12 months: 10.6 and 7.8%, 5 years: 42.0 and 35.9%, for prevalent and incident patients, respectively). CONCLUSIONS: Results of our descriptive study suggest that hemodialysis patients treated within a PPP-care model framework received care complying with recommended treatment targets and may benefit in terms of hospitalization and mortality outcomes.

ABSTRACT

OBJECTIVE: To update the Cochrane review comparing the effects of home-based and supervised centre-based cardiac rehabilitation (CR) on mortality and morbidity, quality of life, and modifiable cardiac risk factors in patients with heart disease. METHODS: Systematic review and meta-analysis. The Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, PsycINFO and CINAHL were searched up to October 2014, without language restriction. Randomised trials comparing home-based and centre-based CR programmes in adults with myocardial infarction, angina, heart failure or who had undergone coronary revascularisation were included. RESULTS: 17 studies with 2172 patients were included. No difference was seen between home-based and centre-based CR in terms of: mortality (relative risk (RR) 0.79, 95% CI 0.43 to 1.47); cardiac events; exercise capacity (mean difference (MD) -0.10, -0.29 to 0.08); total cholesterol (MD 0.07 mmol/L, -0.24 to 0.11); low-density lipoprotein cholesterol (MD -0.06 mmol/L, -0.27 to 0.15); triglycerides (MD -0.16 mmol/L, -0.38 to 0.07); systolic blood pressure (MD 0.2 mm Hg, -3.4 to 3.8); smoking (RR 0.98, 0.79 to 1.21); health-related quality of life and healthcare costs. Lower high-density lipoprotein cholesterol (MD -0.07 mmol/L, -0.11 to -0.03, p=0.001) and lower diastolic blood pressure (MD -1.9 mm Hg, -0.8 to -3.0, p=0.009) were observed in centre-based participants. Home-based CR was associated with slightly higher adherence (RR 1.04, 95% CI 1.01 to 1.07). CONCLUSIONS: Home-based and centre-based CR provide similar benefits in terms of clinical and health-related quality of life outcomes at equivalent cost for those with heart failure and following myocardial infarction and revascularisation.

ABSTRACT

Cell-mediated immunity assays could be valuable for risk assessment of organ donors, but no data exist on their feasibility in deceased donors. In this study, 105 deceased donors (52.3 ± 16.9 years) were screened at the time of organ procurement. Pathogen-specific stimulation was performed using a cytomegalovirus (CMV) lysate, tuberculin (purified protein derivative [PPD]) and soluble Mycobacterium tuberculosis-specific ESAT-6/CFP-10 proteins in combination with an in-house fluorescence-activated cell sorting (FACS) assay or commercial assay formats (QuantiFERON-CMV/TB for ELISA, T-SPOT.TB for ELISPOT). CMV-IgG antibody titers were determined as gold standard for CMV infection; 51.4% of samples were CMV seropositive. Indeterminate results were observed in 47.6% of ELISA, 12.5% of FACS and 0% of ELISPOT assays. Agreement with serology was highest for FACS (95.6%, κ = 0.91), followed by ELISPOT (84.0%, κ = 0.68) and ELISA (80.0%, κ = 0.60). Agreement between ELISA and serology increased if the CMV lysate was used as stimulus (96.7%, κ = 0.92). Among the T cell assays, agreement between ELISPOT and FACS was highest (κ = 0.70). PPD-positive results among valid samples differed between assays (26.5% for ELISA, 23.1% for FACS and 50.5% for ELISPOT); 2.0% were QuantiFERON-TB positive, 3.3% were ESAT-6/CFP-10-positive in FACS and 13.4% were positive in the T-SPOT.TB assay. In conclusion, cellular immunity may be analyzed from samples of deceased donors, although the assays differ in the rate of positivity and indeterminate results.

ABSTRACT

OBJECTIVES: To investigate the harmful health effects of taking ecstasy (3,4-methylenedioxymethamphetamine, MDMA) for recreational purposes. DATA SOURCES: MEDLINE, EMBASE, PsycINFO and Web of Knowledge were searched. Additional information on deaths was collected from the General Mortality Register (GMR) and the Special Mortality Register collated by the National Programme on Substance Abuse Deaths (np-SAD). REVIEW METHODS: Studies were categorised according to design, with systematic research syntheses (Level I evidence) the most valid and least open to bias. Where Level I evidence was not available, controlled observational studies (Level II evidence) were systematically reviewed. If neither Level I nor Level II evidence was available, uncontrolled case series and case reports (Level III evidence) were systematically surveyed. Data were extracted by one reviewer and a sample checked by a second. The heterogeneity of Level II evidence was addressed by undertaking stratified analyses for current and former ecstasy users and comparing them either with control groups using other illegal drugs but not ecstasy (polydrug controls) or with controls naïve to illegal drugs (drug-naïve controls). Statistical heterogeneity was minimised by using a random-effects model throughout and investigated using study-level regression analysis (metaregression). RESULTS: Five Level I syntheses were identified; for each it was difficult to ascertain the exact methods adopted and evidence included. Small but significant deficits for ecstasy users compared to controls were reported in areas relating to attention, memory, psychomotor speed, executive systems functioning, and self-reported depressive symptoms. Data from Level II studies were directly pooled for seven individual outcomes, suggesting that ecstasy users performed worse than controls on common measures of immediate and delayed verbal recall (RAVLT, RBMT, digit span). No difference was seen in IQ (NART). The 915 outcome measures identified in Level II studies were analysed in broad domains: immediate and delayed verbal and visual memory, working memory, two measures of attention, three measures of executive function, perceptual organisation, self-rated depression, memory and anxiety, and impulsivity measured objectively and subjectively. Ecstasy users performed significantly worse than polydrug controls in 13/16 domains and significantly worse than drug-naïve controls in 7/12 domains for which sufficient data were available. The largest, most consistent exposure effects were seen in meta-analyses of memory (especially verbal and working memory, with less marked effects seen in visual memory). Former ecstasy users frequently showed deficits that matched or exceeded those seen amongst current users. At aggregate level, the effects do not appear to be dose-related, but are variably confounded by other drug use, particularly alcohol. Of Level III evidence, in the 10 years to 2006, the np-SAD and the GMR recorded an average of around 50 drug-related deaths per year involving ecstasy; it was the sole drug implicated in around 10 cases per year. Retrospective case series, based on hospital emergency department records, reported a death rate of 0-2% from emergency admissions related to ecstasy. Two major syndromes are most commonly reported as the immediate cause of death in fatal cases: hyperthermia and hyponatraemia. CONCLUSIONS: A broad range of relatively low-quality literature suggests that recreational use of ecstasy is associated with significant deficits in neurocognitive function (particularly immediate and delayed verbal memory) and increased psychopathological symptoms. The clinical significance of the exposure effect in individual cases will be variable but, on average, deficits are likely to be relatively small. Ecstasy is associated with a range of acute harms but appears to be a rare cause of death in isolation.
