Abstract

Background and Objectives

Systematic reviews (SRs) are time and resource intensive, requiring approximately 1 year from protocol registration to submission for publication. Our aim was to describe the process, facilitators, and barriers to completing the first 2-week full SR.

Study Design and Setting

We systematically reviewed evidence of the impact of increased fluid intake, on urinary tract infection (UTI) recurrence, in individuals at risk for UTIs. The review was conducted by experienced systematic reviewers with complementary skills (two researcher clinicians, an information specialist, and an epidemiologist), using Systematic Review Automation tools, and blocked off time for the duration of the project. The outcomes were time to complete the SR, time to complete individual SR tasks, facilitators and barriers to progress, and peer reviewer feedback on the SR manuscript. Times to completion were analyzed quantitatively (minutes and calendar days); facilitators and barriers were mapped onto the Theoretical Domains Framework; and peer reviewer feedback was analyzed quantitatively and narratively.

Results

The SR was completed in 61 person-hours (9 workdays; 12 calendar days); accepted version of the manuscript required 71 person-hours. Individual SR tasks ranged from 16 person-minutes (deduplication of search results) to 461 person-minutes (data extraction). The least time-consuming SR tasks were obtaining full-texts, searches, citation analysis, data synthesis, and deduplication. The most time-consuming tasks were data extraction, write-up, abstract screening, full-text screening, and risk of bias. Facilitators and barriers mapped onto the following domains: knowledge; skills; memory, attention, and decision process; environmental context and resources; and technology and infrastructure. Two sets of peer reviewer feedback were received on the manuscript: the first included 34 comments requesting changes, 17 changes were made, requiring 173 person-minutes; the second requested 13 changes, and eight were made, requiring 121 person-minutes.

Conclusion

A small and experienced systematic reviewer team using Systematic Review Automation tools who have protected time to focus solely on the SR can complete a moderately sized SR in 2 weeks.

Background

Systematic reviews (SRs) synthesize evidence to answer a specific question, using methods that are transparent and reproducible. They are considered the highest-level of evidence to underpin clinical and policy decisions.

However, SRs are time and resource intensive, requiring a median of five researchers and 41 weeks to submit to a journal [personal communication, Kathryn Kaiser; [1]]. A median-sized SR search yields 1,781 references (range: 27–92,020) and requires a title/abstract screen of

The systematic review

We completed an SR of randomized controlled trials (RCTs) assessing the impact of increased fluid intake on urinary tract infection (UTI) recurrence, antimicrobial use, and UTI symptoms, in individuals at risk for UTIs [5]. We included RCTs which compared interventions involving increased fluid intake (e.g., water, juice) to those not involving increased fluids. Searches identified 1,694 references; eight trials were included, and 4 meta-analyses were conducted (Table 1). This was a full SR,

Time to complete the full systematic review

The SR was completed in 12 calendar days (between 21 January and 1 February 2019), working across a 5-day work week and a 4-day work week (because of a public holiday) (Table 4). A standard work week at our university is 37.5 hours (7.5 hours a day).

The SR commenced on 21 January 2019, with an all-author meeting (A.M.S., J.C., C.D.M., and P.G.) during which two authors (P.G. and C.D.M.) disclosed the PICO question to the rest of the team (A.M.S. and J.C.). The work on the protocol commenced

Discussion

Our SR team included four members (compared to a median of five for an SR), required screening of 1,694 studies (slightly less than the median of 1,781), and was completed in 61 person-hours or 9 working days. The time to journal submission was 66 person-hours (16 calendar days), which represents a considerable improvement on the median time to journal submission of 41 weeks (Borah et al. 2017). The final, publishable version of the manuscript required 71 person-hours.

Conclusion

A small and experienced SR team, using SRA tools who have protected time to focus solely on the SR can complete a moderately sized SR in 2 weeks.
