“…81,85,86 The other studies of first-generation LVADs were a cohort analytic study comparing the short-and long-term use of the Novacor LVAD, 87 a case series of the Toyobo LVAD, 88 and two case reports of the Thoratec device. 89,90 Of the five studies of second-generation LVADs, three were before and after cohort studies of the MicroMed DeBakey LVAD [91][92][93] and the other two were case series of the Jarvik 2000 LVAD, one of which was a multicentre case series, with individual centres reporting their patient data at different periods of follow-up for different subgroups.…”

“…The methodological quality of the three before and after cohort studies evaluating the MicroMed DeBakey device [91][92][93] was judged to be weak (Appendix 17). These studies are subsets of a multicentre study and are therefore likely to include some repeat observations in their publications.…”

“…Although the authors of these studies were contacted to establish the possible overlap, they were unable to clarify the position. There was a moderate 92 to high 91,93 risk of selection bias in the studies as they provided limited information on the selection of patients. None of the studies discuss the blinding of outcome assessment or the validity and reliability of data collection tools and are considered to be methodologically weak.…”

“…Withdrawals and drop-outs were discussed and patients are analysed on an intention-to-treat basis in two studies, limiting the effects of attrition bias. 92,93 In the other study, limited information is provided on withdrawals and whether the patients were assessed as intention-to-treat. 91 The criteria judging confounding were not assessed as they were thought not to be relevant to before and after cohort studies.…”

“…Some of the centres involved in the study have published their results separately. [91][92][93] One paper reports data from the first 32 of the 51 patients studied to date and may include patients reported by the other centres. 91 Probability of survival in the 32 patients at 30 days was 81%.…”

HTAThe clinical and cost-effectiveness of left ventricular assist devices for end-stage heart failure: a systematic review and economic evaluation NHS R&D HTA ProgrammeT he research findings from the NHS R&D Health Technology Assessment (HTA) Programme directly influence key decision-making bodies such as the National Institute for Health and Clinical Excellence (NICE) and the National Screening Committee (NSC) who rely on HTA outputs to help raise standards of care. HTA findings also help to improve the quality of the service in the NHS indirectly in that they form a key component of the 'National Knowledge Service' that is being developed to improve the evidence of clinical practice throughout the NHS.The HTA Programme was set up in 1993. Its role is to ensure that high-quality research information on the costs, effectiveness and broader impact of health technologies is produced in the most efficient way for those who use, manage and provide care in the NHS. 'Health technologies' are broadly defined to include all interventions used to promote health, prevent and treat disease, and improve rehabilitation and long-term care, rather than settings of care.The HTA Programme commissions research only on topics...
