Damani et al., [38] | Canada | Quasi-experimental approach with pre-post cohort design | Total knee/hip replacement (TKR) surgery | To evaluate waiting time variations among surgeons, proportion of patients receiving surgery within benchmark, Influence across five dimensions of quality of care based on system- level and patient- centred outcomes (Quality accessibility, acceptability, appropriateness, effectiveness and safety). | Provincial health authority | Data were collected both before (June 2011–June 2012) and after implementation (September 3013–September 2014). Improve patient access to surgery by distributing referrals to the surgeon with shortest waiting time (next- available surgeon) and increase the proportion of patients treated within benchmark. | Intervention helped to improve accessibility by reducing waiting time variability among surgeons, all waiting times for TKR and increasing proportion of TKR within benchmark (5.9%). | ROBINS-I Moderate |
Gabbay et al., [39] | Israel | Quasi experimental approach with historical prospective study | Cataract surgery | To evaluate the efficiency of referral triage system which schedules most cataract patients to surgery based on referral letters, with surgery done immediately following the preoperative examination. | A Tertiary referral hospital | Evaluated the performance of the new referral triage system (2015, 12 months) by studying the reason for day-of surgery cancelations against retrospective system. | The novel approach of preoperative triage using referral letters for scheduling surgery, thus minimizing both patient and physician time prior to surgery and direct referral could shorten both costs and time to surgery. | ROBINS-I Moderate |
Coyle et al., [40] | Canada | prospective, blinded, randomized controlled study | Neurosurgery; Elective Lumbar Spinal Surgery | To evaluate whether a self-administered 3-item questionnaire (3IQ) could reprioritize referral appointments and reduce wait times. | Canadian academic tertiary care centre | 280 patients included within 24 months. Randomly assigned to surgeon triaged and patient triaged two groups, assessed for re-prioritisation status and the waiting time. | Reduced the waiting time of intervention group and to identify non-surgical candidates for appropriate managements. Demonstrated the benefit of patient-reported assessments in prioritisation. | ROBINS-I Low |
Do et al., [42] | Australia | Cross-sectional study with longitudinal follow-up | Cataract surgery | To determine the content and diagnostic accuracy of cataract referral letters and assessed whether referral information had sufficient detail to triage patients and inform surgical prioritization. | Two metropolitan public hospitals | A review of referral letters and hospital medical records was undertaken for a total of 400 (2014). Reviewed same after 1 year. | Current referral letters do not have sufficient detail to inform prioritization, and any efforts to prioritize waiting lists will require standardization of cataract referrals. Development of standard referral templates and resources to triage referrals may improve access to surgical services in a timely manner. | ROBINS-I Moderate |
Loginov et al., [41] | USA | Observational study | Elective surgery | To examine patient perspectives on surgical case scheduling, referral and wait time. | Mayo Clinic | 135 respondents completed the survey (2011–2016). The survey had three attributes; patient desired maximum waiting time, choice of date and option to change the surgeon. | There was a positive association between the maximum waiting times sufficient to discuss having another surgeon perform the procedure. | CASP Moderate |
Diamant et al., [43] | Canada | Retrospective study | Bariatric surgery | To examine the impact of patient and operational factors on wait times in a multidisciplinary bariatric surgery program. | Toronto Western Hospital | 1664 referred patients included for the survey (June 2008–July 2011). Waiting time associations screened for the 724 who underwent surgery. | Specific patient profiles and longer waiting are associated. Waiting time did not depend on BMI, age, sex and distance from the bariatric centre. Substance use was associated with longer preoperative evaluation. Certain types of patients should be identified early in the referral process. | ROBINS-I Moderate |
