- C-Gall: preventing recurrent symptoms and complications in adults with uncomplicated symptom
C-Gall: A randomised controlled trial comparing the clinical effectiveness and cost-effectiveness of laparoscopic cholecystectomy compared with observation/conservative management for preventing recurrent symptoms and complications in adults with uncomplicated symptomatic gallstones
Gallstones are common but only one in three people develop symptoms (severe abdominal pain, nausea and vomiting). These are sometimes accompanied by inflammation of the gallbladder (cholecystitis). Painkillers, anti-inflammatory medicines and antibiotics are usually prescribed initially and surgery to remove the gallbladder (cholecystectomy) is advised for medically fit patients. Approximately 70,000 cholecystectomies are performed every year in the UK, with significant costs for the NHS. However, it is known that some patients do not have any more symptoms after the initial episode of pain and that surgery might not be necessary.
This study will identify, across 20 UK hospitals, 430 patients that will be randomly allocated to either receive surgery or conservative management. Participants will be followed for 18 months and the primary outcome measure will be quality of life throughout that period (measured by the area under the curve using the SF-36 instrument).
This study will include a full economic evaluation. We will also consider a model to extend the analysis beyond the clinical follow-up period. The primary economic outcome measure will be incremental cost per QALY.

- DIAMOND: Deep infiltrating endometriosis: management by treatment versus early surgery
Endometriosis is a chronic and often debilitating condition affecting 1 in 10 women in the UK. The condition arises when cells similar to those found in the womb are found elsewhere in the body. Each month, these cells build-up, break down and bleed causing severe symptoms such as chronic pain and infertility.
Occasionally, the endometrial cells grow deeper into tissues and organs, such as the bowel, bladder and vagina, causing a severe form of the condition called deep endometriosis (DE). DE can be treated by taking hormones such as the combined contraceptive pill, that can shrink areas of endometriosis, or by using keyhole (laparoscopic) surgery to remove areas of endometriosis.
The limited research that has been done suggests that for some women with DE who are not considering immediate pregnancy, hormonal treatment over many months could be just as effective as surgery in relieving pain. Clinical guidelines state that either hormones or surgery can be used but are unable to recommend one over the other in the absence of research directly comparing them.
Funded by the National Institute for Health Research (NIHR), the DIAMOND trial is comparing laparoscopic surgery to medical (hormonal) management for the treatment for DE. The economic evaluation will include a within trial assessment of cost-effectiveness at 18 months post randomisation, and modelling to assess cost-effectiveness up to the time of menopause.

- EDNA: Early Detection of Neovascular Age-related macular degeneration
‘Wet’ or neovascular age-related macular degeneration (nAMD) is a leading cause of sight loss in older people. The EDNA study will evaluate five non-invasive diagnostic tests which are easily performed and routinely carried out in the NHS secondary care setting and which fall into two groups: functional and morphological.
The functional tests are visual acuity, Amsler test and self-reported quality of sight. The morphological tests are fundus examination and optical coherence tomography (OCT). The diagnostic accuracy of these tests will be assessed against a reference standard test (fluorescein angiography). The results from this prospective cohort study will be used to inform the development of a decision analytic model, which will model disease progression and the costs and consequences of using the alternative diagnostic test to monitor patients in secondary care. http://www.nets.nihr.ac.uk/projects/hta/1214207.

- E-FREEZE: RCT in embryo transfer in women undergoing in-vitro fertilization
Despite improvements in technology, IVF success rates remain low with an overall live birth rate of 25% per treatment. Additionally, there are concerns about health outcomes for mothers and babies conceived through IVF, particularly after fresh embryo transfer, including maternal ovarian hyperstimulation syndrome (OHSS) and perinatal morbidity. It is believed that high levels of ovarian hormones during ovarian stimulation could create a relatively hostile environment for embryo implantation whilst increasing the risk of OHSS. It has been suggested that electively freezing embryos with the intention of thawing and replacing them within the uterus at a later stage (thawed frozen embryo transfer), instead of fresh embryo transfer, may lead to improved pregnancy rates and fewer complications. This two-arm parallel group randomised controlled trial, across multiple IVF centres in the UK, aims to address this question: http://www.nets.nihr.ac.uk/projects/hta/1311582.

- Oral iron, Intravenous iron or discontinuation of therapy for older adults with treatment-unresponsive iron deficiency anaemia - a pilot randomised controlled trial
Oral iron supplementation is the most common treatment for anaemia but it does not improve anaemia for all people and there are associated side effects. Three broad treatment strategies are possible yet there is no evidence regarding effectiveness or cost-effectiveness for them.
A pilot randomised controlled trial was undertaken to assess the feasibility of conducting a definitive comparative trial of the following three treatment options:
- no treatment,
- oral iron supplementation and
- intravenous iron infusion.

- Pulpotomy for the management of irreversible pulpitis in mature teeth (PIP)
Tooth decay is very common condition. Almost all adults have some decay in their back teeth. Where the tooth decay has spread deep into the nerve, and caused serious and irreversible damage, there are different treatments available. The most common treatments are to take out the tooth or use root canal treatment. Root canal treatment removes all the nerve and is very expensive, time consuming and technically demanding.
A possible alternative is to remove only the infected part of the nerve, which is an easier and quicker treatment. This technique is called pulpotomy. Research has already been conducted in children’s teeth that supports using pulpotomy instead of root canal treatment. However, there are gaps in knowledge about using pulpotomy in adult’s teeth.
The PIP clinical trial compares pulpotomy with root canal treatment in adult patients recruited from dental practices across Scotland and England. The research considers the pain experienced by patients, the impact of treatment on their lives, whether further treatment is needed due to infection and the time and financial costs incurred. Patient questionnaires, X-rays and data from dentists are used to evaluate the success of the two treatments. Dental staff and patients are also interviewed on their views on the two treatments.

- PUrE RCT: The clinical and cost-effectiveness of surgical interventions for stones in the lower pole calyces of the kidney
Kidney stone disease is very common and, although stones in the kidney do not always cause problems, most need treatment. They can cause serious problems, such as pain, infection and kidney failure, with burden to patients, the NHS and society. There are three treatment options in the NHS for stones in the lower part of the kidney: (1) flexible ureterorenoscopy with laser lithotripsy (FURS); (2) percutaneous nephrolithotomy (PNL); and (3) extracorporeal shockwave lithotripsy (ESWL). Each treatment has advantages and disadvantages (benefits and harms) and there is uncertainty about which of these treatments is best to free people from kidney stones and which is best value for patients and the NHS.
This study will randomly allocate 522 patients with smaller stones (diameter ≤ 10 mm) to be treated with either FURS or ESWL and 522 patients with larger stones (10 mm < diameter ≤ 25 mm ) to be treated with either FURS or PNL, with each participant followed up for one year.
The primary outcome is generic health status (EQ-5D-5L) area under the curve (AUC) to 12 weeks post-intervention. This study includes a full economic evaluation. A within trial analysis as well as a simple model to extend the analysis beyond the clinical study follow-up period will be considered.

- REFLeCt trial
REFLECt trial: A Randomised controlled trial to Evaluate the clinical and cost effectiveness of prescribing high concentration FLuoride toothpaste in preventing and treating dEntal Caries in high-risk older adulTs
The RELFECT study is a two arm, parallel group pragmatic open label randomised controlled trial with 36 month follow. The trial will randomise participants from Manchester, Scotland and Northern Ireland. The primary clinical outcome for the study is restoration or extraction due to caries. The health economic outcomes for the study are NHS and patient perspective costs, willingness to pay and net benefit. Two economic analyses will be completed, the first, a within trial analysis over a three year time horizon. Discrete choice experiments will be used to value the trial outcomes within a cost-benefit analysis framework to reflect broader measures of value to patients. The findings will be compared with a standard cost-utility analysis. A micro-simulation modelling study will be conducted to extrapolate the findings of the trial over a participant’s lifetime. This study will provide important information on the value of prescribing a treatment which is increasing in use, without any evidence to support its effectiveness or cost-effectiveness.

- Recurrence of endometriosis: GnRH analogues versus laparoscopic surgery (REGAL) trial
Endometriosis is a common, painful condition affecting one in ten women of childbearing age. It occurs when cells like those lining the womb grow outside it, causing internal bleeding, scarring and pain. Key hole surgery (laparoscopy) is commonly used to destroy areas of endometriosis. However, endometriosis returns in up to half of treated women within five years, and there is uncertainty about how best to treat women, particularly those who wish to preserve their fertility.
Repeat surgery is invasive, expensive and risky, without guaranteeing a cure. A less invasive treatment is monthly or three-monthly injections with Gonadotrophin Releasing hormone (GnRH) analogues. While effective in reducing pain, this type of hormonal treatment has generally only been used for up to a year because of the risk of side effects (hot flushes and night sweats) and concerns about osteoporosis. However, recent research suggests that giving small doses of hormone replacement therapy (HRT) with GnRH analogues can reduce the risk of side effects.
Funded by the National Institute for Health Research (NIHR), this trial will assess the clinical and cost-effectiveness of long-term GnRH analogues with added HRT compared to conservative key hole surgery in women who experience recurrence of pain after surgery but who wish to preserve their fertility.

Recently Completed Projects
- Ezetimibe for treating primary (heterozygous-familial and non-familial) hypercholesterolaemia (Single Technology Assessment for NICE)
Primary hypercholesterolaemia is a form of dyslipidemia characterised by abnormalities of lipoprotein transport associated with high concentrations of cholesterol in the blood. People with hypercholesterolaemia are at increased risk of cardiovascular disease (CVD) owing to the fact that long-term high concentrations of cholesterol are known to accelerate atherosclerosis, the build-up of fatty deposits in the arteries.
This project was carried out as part of the National Institute for Health and Care Excellence (NICE) Single Technology Appraisal Process. The company responsible for ezetimibe (Merck Sharp & Dohme Ltd) submitted an evidence review and an economic model assessing the cost-effectiveness of the drug, alone or in combination with statin treatment, against no treatment or statin alone for the treatment of primary hypercholesterolaemia. The Aberdeen HTA group were commissioned to act as the Evidence Review Group (ERG) for the project, and to provide an independent report reviewing the company’s evidence submission.
Outcome and Translation
Following consideration of the company submission and the ERG report, the NICE appraisal committee recommended ezetimibe as a treatment option for some people with heterozygous-familial and non-familial hypercholesterolaemia: http://www.nice.org.uk/guidance/ta385/chapter/1-Recommendations.

- INTERVAL: Investigation of NICE Technologies for Enabling Risk-Variable-Adjusted-Length dental recalls trial (pilot and follow-on study)
A parallel-group, randomised, controlled comparison of three forms of dental recall strategy (6-month recall, risk-based recall and 24-month recall) evaluated the effectiveness and cost-effectiveness of these dental recall strategies by assessing their impact on maintaining oral health. A cost–benefit analysis was undertaken to assess the efficiency of the alternative recall strategies. Willingness to pay was elicited using a discrete choice experiment.

- Improving the Quality of Dentistry IQUAD
IQuaD: Improving the Quality of Dentistry: a randomised controlled trial comparing oral hygiene advice and periodontal instrumentation for the prevention and management of periodontal disease in dentate adults attending dental primary care
Periodontal disease is the most common oral disease affecting adults. This disease is preventable, yet it remains the major cause of poor oral health worldwide and is the primary cause of tooth loss in older adults. There is a lack of strong evidence to inform clinicians and policy makers of the relative effectiveness (if any) and cost-effectiveness of different types of oral hygiene advice (OHA). The economic evaluation conducted as part of this cluster randomised controlled trial elicited the costs of dental care to both the NHS and patients and equated the data with benefits to patients. Benefits to patients were estimated using a discrete choice experiment administered to a sample of the general population to provide a scoring algorithm with which to weight the outcomes for the patient participants in the trial.
Outcome and Translation
63 dental practices and 1877 participants were recruited. Under Intention To Treat (ITT) analysis there was no evidence of a difference in gingival inflammation/bleeding (the primary clinical effectiveness outcome measure) across any of the randomised groups. There was no clinical benefit from scheduling 6-monthly or 12-monthly scale and polish over not scheduling these treatments unless desired or recommended. Furthermore, there was no clinical benefit of personalised over routine oral hygiene advice in either gingival inflammation/bleeding or patient centred outcomes (including oral health related quality of life).
Compared to standard care, no scale and polish with personalised advice had the greatest NHS: -£15 (-£34 to +£4) and participant: -£64 (-£112 to -£16) cost savings. The DCE shows that the general population value these services greatly and were willing to pay for both scale and polish and personalised advice. WTP for scale and polish was higher than personalised advice. Overall, Personalised OHA with 6-monthly PI had the greatest incremental net benefit to society: +£48 (+£22 to +£74). Sensitivity analyses did not change conclusions. The results of the study provide a dilemma for NHS dental policy makers who must consider whether or not to fund services that are not clinically beneficial but are highly valued by the general population.

- Oral splints for orofacial symptoms: an evidence synthesis
Oral splints are placed by dentists working in the NHS for patients with orofacial signs of symptoms. It is unclear if oral splints are effective or cost-effective, and if they are, which type of splint is the most cost-effective (cheaper pre-fabricated splints or more expensive custom made ones).
This project developed a Markov decision analysis model alongside a systematic review of the clinical effectiveness literature on the use of oral splints for temporomandibular disease (TMD).
Standard reporting methods were used to illustrate uncertainty in findings (deterministic and probabilistic sensitivity analysis). There was a dearth of high quality evidence to populate the model, particularly over the longer time period. An expected value of perfect information (EVPI) analysis explored the value for money of conducting additional research to resolve uncertainty in the cost-effectiveness evidence. Expected value of partial perfect information (EVPPI) analysis was used to identify the most important model parameters on which to obtain future data. The results of these analyses can help to prioritise key areas of future research from a cost-effectiveness view-point.

- Scottish cervical cancer prevention programme
Assessing and modelling the impact of HPV 16/18 immunisation on the performance of current cervical screening and the effectiveness of alternative cervical screening strategies to optimise cancer prevention in the HPV immunisation era
In Scotland, human papilloma virus (HPV) vaccination of females aged 12 to 13 years started, via a school immunisation programme, on 1 September 2008. A ‘catch-up campaign’, targeting females up to the age of 18, ran alongside this. Scotland now moves from the Scottish Cervical Screening Programme to a Scottish Cervical Cancer Prevention Programme, with the aim of further reducing cervical cancer mortality by primary prevention based on HPV immunisation and secondary prevention based on screening. Health Protection Scotland (HPS) is coordinating the introduction of the new immunisation programme, and also established an HPV immunisation project to monitor its impact. Many new questions need to be investigated to inform NHS policy on the future delivery of the combined screening and immunisation programme. Scotland is in a unique position to lead on new research as 16–17-year-olds were immunised in 2008 and become eligible for cervical screening from September 2010. Our research combined routinely collected data on screening and disease detection with data on HPV genotyping and screening test performance to model future screening performance.
Outcome and Translation
This study will inform NHS Scotland policy on future service delivery of the national cervical screening and immunisation programme. Scotland’s research networks and HPS can collaborate effectively using Scotland’s excellent data linkage facilities to further develop and deliver a composite population health intervention for cancer prevention, and improve health outcomes in Scotland.

- Surveillance following endovascular aortic aneurysm repair (EVAR)
The clinical and cost-effectiveness of protocols using contrast-enhanced ultrasound and/or colour duplex ultrasound in the long-term surveillance of endovascular abdominal aortic aneurysm repair
An abdominal aortic aneurysm is a swelling or bulge that causes the wall of the main blood vessel (aorta) to weaken and become pouched or sac-shaped. Large aneurysms can burst, causing massive internal bleeding, which can lead to death. EVAR of the aneurysm has become the preferred treatment option for abdominal aortic aneurysm. EVAR is minimally invasive but it is associated with potential complications of which the most common is the occurrence of an endoleak (blood flow in the aneurysm sac). Consequently, patients who receive EVAR treatment must be followed up for the rest of their life.
CTA is an imaging modality widely used for the surveillance after EVAR. CTA is considered to be very accurate but it is not very good at detecting the direction of blood flow from an endoleak. It also carries the risk of repeated exposure to radiation and to a toxic contrast agent. CDU and CEU have been suggested as possible safer imaging alternatives to CTA but have not been widely adopted. The optimal surveillance strategy with regard to the choice of imaging modalities and the frequency of testing has not been established yet.
This study included a systematic review of the literature to assess the current evidence for the clinical effectiveness and cost-effectiveness of surveillance strategies using CDU and CEU compared with CTA in the surveillance after EVAR. A model based economic evaluation was also conducted as part of the assessment. Publication of the final report is currently pending.
The results of the project will be used by the National Institute for Health and Care Excellence (NICE) to issue clinical guidance in England and Wales on the optimal surveillance strategy after EVAR.
This review is registered with PROSPERO International prospective register of systematic reviews (PROSPERO 2016:CRD4201603475).
Outcome and Translation
The findings from this study will be available to help inform clinical guidelines and research recommendations on surveillance following EVAR.

- TISU: Therapeutic Interventions for Stones of the Ureter
TISU: Therapeutic Interventions for Stones of the Ureter: a multicentre randomised controlled trial of extracorporeal shockwave lithotripsy, as first treatment option, compared with direct progression to ureteroscopic retrieval, for ureteric stones
Urinary stone disease is very common with an estimated prevalence among the general population of 2–3% (1.8 million people in the UK) with males forming stones three times as often as females. All symptomatic urinary tract stones, and ureteric stones in particular, are associated with severe pain and can have a significant impact on patients’ quality of life due to the detrimental effect on their ability to work and the need for hospitalisation. Most ureteric stones can be expected to pass spontaneously with supportive care (painkillers and fluids) possibly aided by drugs such as alpha blockers or calcium channel blockers (conservative management). However, between a fifth and a third of cases require an active intervention (stone removal) because of failure to pass the stone, continuing pain, infection or obstruction to urine drainage.
The two standard active intervention options are extracorporeal shockwave lithotripsy (ESWL) and ureteroscopic stone retrieval. Whilst both ESWL and ureteroscopy appear to be effective in terms of stone clearance they differ in terms of invasiveness, anaesthetic requirement, treatment setting, potentially the number of procedures required to clear the stone, complications, patient reported outcomes (such as severity and duration of pain after intervention, time off work and bothersome urinary symptoms), and cost. There is uncertainty around which is the most clinically effective in terms of stone clearance and the true cost to the NHS and to society (in terms of impact on patient reported health and economic burden).
Outcome and Translation
The findings of this project will inform the decision makers on the most clinical and cost- effective surgical intervention to use in the treatment of ureteric stones. The project will also inform the national guidance on the treatment of patients that present with ureteric stones.
