BackgroundUncertainty exists regarding the best management of patients with degenerative tears of the rotator cuff.ObjectiveTo evaluate the clinical effectiveness and cost-effectiveness of arthroscopic and open rotator cuff repair in patients aged ≥ 50 years with degenerative rotator cuff tendon tears.DesignTwo parallel-group randomised controlled trial.SettingNineteen teaching and district general hospitals in the UK.ParticipantsPatients (n = 273) aged ≥ 50 years with degenerative rotator cuff tendon tears.InterventionsArthroscopic surgery and open rotator cuff repair, with surgeons using their usual and preferred method of arthroscopic or open repair. Follow-up was by telephone questionnaire at 2 and 8 weeks after surgery and by postal questionnaire at 8, 12 and 24 months after randomisation.Main outcome measuresThe Oxford Shoulder Score (OSS) at 24 months was the primary outcome measure. Magnetic resonance imaging evaluation of the shoulder was made at 12 months after surgery to assess the integrity of the repair.ResultsThe mean OSS improved from 26.3 [standard deviation (SD) 8.2] at baseline to 41.7 (SD 7.9) at 24 months for arthroscopic surgery and from 25.0 (SD 8.0) at baseline to 41.5 (SD 7.9) at 24 months for open surgery. When effect sizes are shown for the intervention, a negative sign indicates that an open procedure is favoured. For the intention-to-treat analysis, there was no statistical difference between the groups, the difference in OSS score at 24 months was –0.76 [95% confidence interval (CI) –2.75 to 1.22;p = 0.452] and the CI excluded the predetermined clinically important difference in the OSS of 3 points. There was also no statistical difference when the groups were compared per protocol (difference in OSS score –0.46, 95% CI –5.30 to 4.39;p = 0.854). The questionnaire response rate was > 86%. At 8 months, 77% of participants reported that shoulder problems were much or slightly better, and at 24 months this increased to 85%. There were no significant differences in mean cost between the arthroscopic group and the open repair group for any of the component resource-use categories, nor for the total follow-up costs at 24 months. The overall treatment cost at 2 years was £2567 (SD £176) for arthroscopic surgery and £2699 (SD £149) for open surgery, according to intention-to-treat analysis. For the per-protocol analysis there was a significant difference in total initial procedure-related costs between the arthroscopic group and the open repair group, with arthroscopic repair being more costly by £371 (95% CI £135 to £607). Total quality-adjusted life-years accrued at 24 months averaged 1.34 (SD 0.05) in the arthroscopic repair group and 1.35 (SD 0.05) in the open repair group, a non-significant difference of 0.01 (95% CI –0.11 to 0.10). The rate of re-tear was not significantly different across the randomised groups (46.4% and 38.6% for arthroscopic and open surgery, respectively). The participants with tears that were impossible to repair had the lowest OSSs, the participants with re-tears had slightly higher OSSs and the participants with healed repairs had the most improved OSSs. These findings were the same when analysed per protocol.ConclusionIn patients aged > 50 years with a degenerative rotator cuff tear there is no difference in clinical effectiveness or cost-effectiveness between open repair and arthroscopic repair at 2 years for the primary outcome (OSS) and all other prespecified secondary outcomes. Future work should explore new methods to improve tendon healing and reduce the high rate of re-tears observed in this trial.Trial registrationCurrent Controlled Trials ISRCTN97804283.FundingThis project was funded by the National Institute for Health Research Health Technology Assessment programme and will be published in full inHealth Technology Assessment; Vol. 19, No. 80.

There is no evidence of difference in effectiveness between open and arthroscopic repair of rotator cuff tears. The rate of re-tear is high in both groups, for all sizes of tear and ages and this adversely affects the outcome. Cite this article: Bone Joint J 2017;99-B:107-15.

ObjectivesThrough the National Health Service (NHS) Bowel Cancer Screening Programme (BCSP), men and women in England aged between 60 and 74 years are invited for colorectal cancer (CRC) screening every 2 years using the guaiac faecal occult blood test (gFOBT). The aim of this analysis was to estimate the cost–utility of the faecal immunochemical test for haemoglobin (FIT) compared with gFOBT for a cohort beginning screening aged 60 years at a range of FIT positivity thresholds.DesignWe constructed a cohort-based Markov state transition model of CRC disease progression and screening. Screening uptake, detection, adverse event, mortality and cost data were taken from BCSP data and national sources, including a recent large pilot study of FIT screening in the BCSP.ResultsOur results suggest that FIT is cost-effective compared with gFOBT at all thresholds, resulting in cost savings and quality-adjusted life years (QALYs) gained over a lifetime time horizon. FIT was cost-saving (p<0.001) and resulted in QALY gains of 0.014 (95% CI 0.012 to 0.017) at the base case threshold of 180 µg Hb/g faeces. Greater health gains and cost savings were achieved as the FIT threshold was decreased due to savings in cancer management costs. However, at lower thresholds, FIT was also associated with more colonoscopies (increasing from 32 additional colonoscopies per 1000 people invited for screening for FIT 180 µg Hb/g faeces to 421 additional colonoscopies per 1000 people invited for screening for FIT 20 µg Hb/g faeces over a 40-year time horizon). Parameter uncertainty had limited impact on the conclusions.ConclusionsThis is the first published economic analysis of FIT screening in England using data directly comparing FIT with gFOBT in the NHS BSCP. These results for a cohort starting screening aged 60 years suggest that FIT is highly cost-effective at all thresholds considered. Further modelling is needed to estimate economic outcomes for screening across all age cohorts simultaneously.
