Systematic Reviews for Consultancy

Drawing on our extensive experience of working with partners, we offer a range of systematic review products for consultancy and the NHS that can be tailored to the needs of customers. We can focus on a range of study types, including RCTs, cohort studies, case-control studies, cross-sectional data, diagnostic studies, prognostic studies and qualitative studies. We can also provide mixed methods syntheses of qualitative and quantitative evidence.

Review products

Broad systematic review: Produced to standards required for submission to reimbursement bodies such as NICE or submission to a peer reviewed journal. Can provide information for strategic planning in industry. Employing highest standard of review methodologies. Can include multiple interventions, broadly or narrowly defined populations and multiple outcomes. Analysis can include narrative synthesis, meta analysis (quantitative) or meta synthesis (qualitative). Estimated time: 6 -12 months

Narrow systematic review: Produced to the standards outlined above, but are narrower in focus, e.g. only RCTs, one intervention and fewer outcomes. Estimated time: 1 - 6 months, depending on available evidence

Systematic reviews to support network meta analysis/mixed treatment comparisons: Produced to standards required for a submission to reimbursement bodies such as NICE. Where multiple interventions are to be compared, a wider and more comprehensive search and inclusion strategy is required. We recommend: use of a clearly defined population, use of RCTs only, clearly stated interventions and a network limited to an agreed level and agreed number of outcomes. Estimated time: 6 - 12 months

Review of systematic reviews: Where multiple systematic reviews are already published, a quick approach to inform strategy or plan a submission to NICE might be to review existing reviews. Estimated time: 1 - 3 months

Update of systematic review: Produced to standards required for submission to reimbursement bodies such as NICE. Can only be used to update existing high quality reviews. Search strategy is replicated from the date of the last search. Any new studies are data extracted and, if data allows, a new meta-analysis or meta-synthesis performed. Estimated time: 2 - 6 weeks

Updating a review (quick): Employs limited search strategy, or addition of known new data, such as data provided by funder. Estimated time: 2 -4 weeks

Rapid review: Where timescales are tight, a rapid review provides a methodologically transparent review, which includes limited search techniques, little or no quality assessment and limited data extraction. These reviews may miss some evidence. Estimated time: 1 - 3 months

Review of model parameters (systematic): Where a model parameter is key, or data is difficult to identify, a systematic search provides a high quality and accurate source of data. Includes quality assessment and data extraction. Estimated time: 1 week - 1 month

Review of model parameters (quick): As above, but limited searches, no quality assessment and focussed on one outcome. Transparent methods, but may miss some evidence. Estimated time: 1 week

Research reports: Where no synthesis of evidence is required. Research reports employ good quality searches, quality assessment and a summary of each study. Estimated time: 1 - 3 months

Mapping reviews: to outline the available evidence in a broad healthcare topic or to identify research gaps. Include limited systematic searches, limited data extraction, and a variety of outputs which can include numerical or narrative summaries of available studies, their outcomes, study design, etc. Estimated time: 1 - 3 months
