HTA NIHR Health Technology Assessment programmeT he Health Technology Assessment (HTA) programme, part of the National Institute for Health Research (NIHR), was set up in 1993. It produces high-quality research information on the effectiveness, costs and broader impact of health technologies for those who use, manage and provide care in the NHS. 'Health technologies' are broadly defined as all interventions used to promote health, prevent and treat disease, and improve rehabilitation and long-term care. The research findings from the HTA programme directly influence decision-making bodies such as the National Institute for Health and Clinical Excellence (NICE) and the National Screening Committee (NSC). HTA findings also help to improve the quality of clinical practice in the NHS indirectly in that they form a key component of the 'National Knowledge Service'. The HTA programme is needs led in that it fills gaps in the evidence needed by the NHS. There are three routes to the start of project...
BackgroundIt is estimated that only 39% of men and 29% of women in England achieve the levels of physical activity that are recommended to protect health and prevent disease. One approach to addressing this problem has been the development of exercise referral schemes (ERSs), in which health professionals refer patients to external exercise providers. These schemes have been widely rolled out across the UK despite concerns that they may not produce sustained changes in levels of physical activity and, therefore, may not be cost-effective interventions. The evidence to determine clinical effectiveness and cost-effectiveness was evaluated in 2009. This review seeks to update this earlier work by incorporating new evidence and re-examining the cost-effectiveness.ObjectivesTo assess the clinical effectiveness and cost-effectiveness of ERSs compared with usual care.DesignExhaustive searches of relevant electronic databases and journals were undertaken to identify new studies evaluating ERSs using a randomised controlled trial (RCT) design. RCTs that incorporated a qualitative evaluation of the intervention were identified in order to explore the barriers and facilitators to the uptake of and adherence to ERSs. Data were extracted using a previously designed tool and study quality assessed for potential bias. Where data could be pooled, meta-analyses were carried out. Qualitative analysis was also undertaken using a thematic approach. The cost-effectiveness was evaluated using a Markov structure which estimated the likelihood of becoming physically active and the subsequent risk reduction on coronary heart disease (CHD), stroke and type 2 diabetes mellitus. The model adopts a lifetime horizon, and a NHS and Personal Social Services perspective was taken with discounting at 1.5% for both costs and benefits.ResultsThe search identified one new RCT and one new qualitative study. The new data were pooled with existing data from the 2011 review by Paveyet al.[Pavey TG, Anokye N, Taylor AH, Trueman P, Moxham T, Fox KR,et al.The clinical effectiveness and cost-effectiveness of exercise referral schemes: a systematic review and economic evaluation.Health Technol Assess2011;15(44)] to give a total of eight studies with 5190 participants. The proportion of individuals achieving 90–150 minutes of at least moderate-intensity activity per week at 6–12 months’ follow-up was greater for ERSs than usual care (relative risk 1.12; 95% confidence interval 1.04 to 1.20). Older patients and those referred for CHD risk factors appeared to be more likely than others to increase their levels of physical activity. Qualitative evidence suggests that interventions enabling the development of social support networks are beneficial in promoting uptake and adherence. Exercise referral gained 0.003 quality-adjusted life-years (QALYs) at an additional cost of £225 per person. The estimated mean incremental cost-effectiveness ratio (ICER) in the probabilistic sensitivity analysis was £76,276. In the univariate sensitivity analysis the results were very sensitive (ICERs ranged from < £30,000 to > £100,000) to changes in the effect of ERSs on physical activity uptake and the duration of the protective effects and the direct health-related quality-of-life gains attributable to physical activity.ConclusionsExercise referral schemes result in a small improvement in the number of people who increase their levels of physical activity. The cost-effectiveness analysis indicates that the ICER for ERSs compared with usual care is around £76,000 per QALY, although the cost-effectiveness of ERSs is subject to considerable uncertainty.Study registrationThis study is registered as PROSPERO CRD42013005200.FundingNational Institute for Health Research Health Technology Assessment programme.
Objectives: To estimate the effectiveness, cost-effectiveness and resource impact of faecal occult blood testing (FOBT) and flexible sigmoidoscopy (FSIG) screening options for colorectal cancer to inform the Department of Health's policy on bowel cancer screening in England. Methods: We developed a state transition model to simulate the life experience of a cohort of individuals without polyps or cancer through to the development of adenomatous polyps and malignant carcinoma and subsequent death in the general population of England. The costs, effects and resource impact of five screening options were evaluated: (a) FOBT for individuals aged 50-69 (biennial screening); (b) FOBT for individuals aged 60-69 (biennial screening); (c) once-only FSIG for individuals aged 55; (d) once-only FSIG for individuals aged 60; and (e) once-only FSIG for individuals aged 60, followed by FOBT for individuals aged 61-70 (biennial screening). Results: The model suggests that screening using FSIG with or without FOBT may be cost-saving and may produce additional benefits compared with a policy of no screening. The marginal cost-effectiveness of FOBT options compared to a policy of no screening is estimated to be below £3000 per quality adjusted life year gained. Conclusions: Screening using FOBT and/or FSIG is potentially a cost-effective strategy for the early detection of colorectal cancer. However, the practical feasibility of alternative screening programmes is inevitably limited by current pressures on endoscopy services.C olorectal cancer (CRC) is the third most common form of cancer in the UK, where approximately 34 500 new cases of CRC are diagnosed each year, 1 resulting in around 16 200 CRC-related deaths annually. 2 Recent evidence from randomised controlled trials (RCT) of faecal occult blood testing (FOBT) suggest that population-based screening for CRC can significantly reduce mortality, 3-7 and early results from the UK demonstration pilot suggest that population screening using FOBT is feasible within current healthcare resource constraints. 8 Evidence relating to the effectiveness of flexible sigmoidoscopy (FSIG) as a screening option for CRC is less well established, although three RCTs are currently underway. [9][10][11] It has been estimated that current annual expenditures on the surgical, adjuvant and palliative treatment of CRC are around £300 million 11 ; this is likely to increase substantially as the National Institute for Health and Clinical Excellence (NICE) issues guidance on newer cytotoxic therapies for the adjuvant and palliative treatment of CRC. While the introduction of a national CRC screening programme would inevitably entail substantial immediate costs, such expenditures may be offset through a reduction in CRC incidence and through the less intensive treatment required for cancers detected earlier. Two mathematical models have been previously developed to estimate the cost-effectiveness of FOBT screening in the UK, based upon the Nottingham trial 12-14 and the UK FOBT demonstration pilot. 15 B...
BackgroundUlcerative colitis (UC) is the most common form of inflammatory bowel disease in the UK. UC can have a considerable impact on patients’ quality of life. The burden for the NHS is substantial.ObjectivesTo evaluate the clinical effectiveness and safety of interventions, to evaluate the incremental cost-effectiveness of all interventions and comparators (including medical and surgical options), to estimate the expected net budget impact of each intervention, and to identify key research priorities.Data sourcesPeer-reviewed publications, European Public Assessment Reports and manufacturers’ submissions. The following databases were searched from inception to December 2013 for clinical effectiveness searches and from inception to January 2014 for cost-effectiveness searches for published and unpublished research evidence: MEDLINE, EMBASE, Cumulative Index to Nursing and Allied Health Literature, The Cochrane Library including the Cochrane Systematic Reviews Database, Cochrane Controlled Trials Register, Database of Abstracts of Reviews of Effects, the Health Technology Assessment database and NHS Economic Evaluation Database; ISI Web of Science, including Science Citation Index, and the Conference Proceedings Citation Index-Science and Bioscience Information Service Previews. The US Food and Drug Administration website and the European Medicines Agency website were also searched, as were research registers, conference proceedings and key journals.Review methodsA systematic review [including network meta-analysis (NMA)] was conducted to evaluate the clinical effectiveness and safety of named interventions. The health economic analysis included a review of published economic evaluations and the development of a de novo model.ResultsTen randomised controlled trials were included in the systematic review. The trials suggest that adult patients receiving infliximab (IFX) [Remicade®, Merck Sharp & Dohme Ltd (MSD)], adalimumab (ADA) (Humira®, AbbVie) or golimumab (GOL) (Simponi®, MSD) were more likely to achieve clinical response and remission than those receiving placebo (PBO). Hospitalisation data were limited, but suggested more favourable outcomes for ADA- and IFX-treated patients. Data on the use of surgical intervention were sparse, with a potential benefit for intervention-treated patients. Data were available from one trial to support the use of IFX in paediatric patients. Safety issues identified included serious infections, malignancies and administration site reactions. Based on the NMA, in the induction phase, all biological treatments were associated with statistically significant beneficial effects relative to PBO, with the greatest effect associated with IFX. For patients in response following induction, all treatments except ADA and GOL 100 mg at 32–52 weeks were associated with beneficial effects when compared with PBO, although these were not significant. The greatest effects at 8–32 and 32–52 weeks were associated with 100 mg of GOL and 5 mg/kg of IFX, respectively. For patients in remission following induction, all treatments except ADA at 8–32 weeks and GOL 50 mg at 32–52 weeks were associated with beneficial effects when compared with PBO, although only the effect of ADA at 32–52 weeks was significant. The greatest effects were associated with GOL (at 8–32 weeks) and ADA (at 32–52 weeks). The economic analysis suggests that colectomy is expected to dominate drug therapies, but for some patients, colectomy may not be considered acceptable. In circumstances in which only drug options are considered, IFX and GOL are expected to be ruled out because of dominance, while the incremental cost-effectiveness ratio for ADA versus conventional treatment is approximately £50,300 per QALY gained.LimitationsThe health economic model is subject to several limitations: uncertainty associated with extrapolating trial data over a lifetime horizon, the model does not consider explicit sequential pathways of non-biological treatments, and evidence relating to complications of colectomy was identified through consideration of approaches used within previous models rather than a full systematic review.ConclusionsAdult patients receiving IFX, ADA or GOL were more likely to achieve clinical response and remission than those receiving PBO. Further data are required to conclusively demonstrate the effect of interventions on hospitalisation and surgical outcomes. The economic analysis indicates that colectomy is expected to dominate medical treatments for moderate to severe UC.Study registrationThis study is registered as PROSPERO CRD42013006883.FundingThe National Institute for Health Research Health Technology Assessment programme.
