“…6-32 Thirteen of these studies examined the relation between wait time and outcomes, [6][7][8][9][10][11][12][13][14][15][16][17][18] and 19 studies examined the variables that modified this relation.…”

“…17 However, further investigation into the factors that affect wait times is necessary, because many modifying variables have been examined only superficially. In regards to outcome modifiers, the findings of our review are limited in that most of the evidence presented is based on expert opinion rather than on empirical investigation.…”

Background: Cataract surgery is the most common operative procedure performed in Canada, and how patients are affected by wait times for this surgery has important clinical, public health and health policy considerations. We conducted a systematic review to understand the relation between wait time for cataract surgery and patient outcomes and the variables that modify this relation. Methods:We performed an electronic search of 11 databases and the proceedings of 4 conferences. The search was restricted to studies published after the transition to phacoemulsification (1990). We assessed the quality of the included studies using the Jadad Scale for randomized controlled trials and the Newcastle-Ottawa Scale for cohort and case-control studies. The data were found to be inappropriate for meta-analysis, thus we performed a qualitative synthesis. Results:We found a total of 27 studies that met our inclusion criteria. When these studies were reviewed, a dichotomy was observed for the wait time-outcome relation: outcomes associated with wait times of ≤ 6 weeks were better than outcomes associated with wait times of ≥ 6 months. Patients who waited more than 6 months to receive cataract surgery experienced more vision loss, a reduced quality of life and had an increased rate of falls compared with patients who had wait times of less than 6 weeks. The outcomes associated with wait times between 6 weeks and 6 months remain unclear. Interpretation:Patients who wait more than 6 months for cataract surgery may experience negative outcomes during the wait period, including vision loss, a reduced quality of life and an increased rate of falls.

“…However, this does not address the underlying issue of the impact of the actual length of wait as it pertains to physical functioning parameters [15]. Medical expert consensus based criteria tools for prioritizing patients on the waiting list for surgery may facilitate a more broad based specialty equity in the access to surgical treatment [5].…”

The impact of surgical wait time on patient-based outcomes in posterior lumbar spinal surgery

et al. 2007

A prospective observational study was conducted on patients undergoing posterior lumbar spine surgery for degenerative spinal disorders. The study purpose was to evaluate the effect of wait time to surgery on patient derived generic and disease specific functional outcome following surgery. A prolonged wait to surgery may adversely affect surgical outcome. Although there is literature on the effect of wait time to surgery in surgical fields such as oncology, cardiac, opthamologic, and total joint arthroplasty, little is known regarding the effect of wait time to surgery as it pertains to the spinal surgical population. Consecutive patients undergoing elective posterior lumbar spinal surgery for degenerative disorders were recruited. Short-Form 36 and Oswestry disability questionnaires were administered (pre-operatively, and at 6 weeks, 6 months, and 1 year post-operatively). Patients completed a questionnaire regarding their experience with the wait time to surgery. The study cohort consisted of 70 patients with follow-up in 53/70 (76%). Time intervals from the onset of patient symptoms to initial consultation by family physician through investigations, spinal surgical consultation and surgery were quantified. Time intervals were compared to patient specific improvements in reported outcome following surgery using Cox Regression analysis. The effect of patient and surgical parameters on wait time was evaluated using the median time as a reference for those patients who had either a longer or shorter wait. Significant improvements in patient derived outcome were observed comparing post-operative to pre-operative baseline scores. The greatest improvements were observed in aspects relating to physical function and pain. A longer wait to surgery was associated with less improvement in outcome following surgery (SF-36 domains of BP, GH, RP, VT). A longer wait time to surgery negatively influences the results of posterior lumbar spinal surgery for degenerative conditions as quantified by patient derived functional outcome measures. The parameters of pain severity and physical aspects of function appear to be the most significantly affected.

“…Waiting lists and unmet needs also generate dissatisfaction, represent high maintenance costs [8], and lower the quality of the health care system [9]. Waiting list prioritization systems have been developed [10][11][12][13][14] to treat patients on the basis of clinical need and ethical priority rather than simply on a first-come, first-served basis that meets targets without concern for clinical priority [15]. These systems contain criteria for prioritization based on clinical conditions, social demands, and patient-based preferences.…”

The Prioritization of Patients on Waiting Lists for Cataract Surgery: Validation of the Western Canada Waiting List Project Cataract Priority Criteria Tool

Abstract: These data provide some evidence to support the convergent and predictive validity of the PCS. Multiple patient outcomes should be used in the evaluation of the validity of priority scores.
