Purpose: To assess the validity of the Cataract Priority Criteria Score (PCS), developed by the Western Canada Waiting List (WCWL) Project to determine patient prioritization for cataract surgery. Methods: Ophthalmologists assessed consecutive patients with the PCS and a visual analogue scale of urgency (VAS Urgency). Patients were mailed questionnaires pre- and post-surgery. Outcome measures were the Visual Function Assessment (VFA), EuroQol (EQ-5D), and best-corrected visual acuity. Results: The sample of 253 patients was 58% female (mean age, 73.7 years); 166 completed pre-and post-surgery VFA. The correlation of the PCS and VAS Urgency was 0.65 (p = 0.000). Adjusting for age, first or second eye surgery, and post-operative complication, the PCS predicted improvement in the VFA and visual acuity (p < .05). Conclusions: 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 scor...

Background: Lengthy waiting times for cataract surgery are an important issue in countries with publicly funded health care systems. To improve the fairness, timeliness, and certainty of waiting-time management, the Western Canada Waiting List Project has developed priority criteria scores (PCSs) related to urgency and linked to maximum acceptable waiting times (MAWTs). The purpose of our study was to compare patient and physician perspectives of MAWT for different levels of urgency. A second aim was to assess the determinants of patient and surgeon perspectives on MAWT. Methods: Ophthalmologists assessed consecutive patients waitlisted for cataract surgery. Data included a MAWT, a visual analogue scale of urgency (VAS urgency), and the cataract PCS. Patients were mailed questionnaires to assess their perspectives of MAWT and VAS urgency. They were also sent a measure of visual function called the Visual Function Assessment. We used hierarchical linear regression to assess the determinants of MAWT. Results: The mean age of the 213 patients was 73.9 years; 56.8% were female and 71.8% were booked for first eye surgery. Physician-rated MAWT was significantly longer than patient-rated MAWT (mean 15.1 vs. 9.9 weeks). Median physician MAWTs ranged from 12 (most urgent) to 20 (least urgent) weeks, and patient MAWTs, from 4 to 8 weeks. A 3-step hierarchical linear regression model showed that, after adjusting for age and sex, the priority criteria added significantly to the surgeon model ( R 2 change=0.22). Significant predictors were ocular comorbidity, impairment in visual function, and ability to work or live independently or care for dependents. After the addition of VAS urgency, the final model explained 42% of the variance in surgeon MAWT. Significant predictors were age-related macular degeneration and VAS urgency. A 4-step hierarchical regression model for patient MAWT showed that after step 2, sex and visual acuity in the nonsurgery eye were significant predictors. The final model accounted for 11% of the variance in patient MAWT. Significant predictors were sex (males had lower MAWT) and VAS urgency. Interpretation: Patient and physician views on MAWT differ, yet both are critical to a fair process for developing standardized waiting times related to levels of urgency. Results from this study provide initial inputs to the formulation of benchmark waiting times for different levels of the cataract PCS.

Aims: To assess determinants of patient satisfaction with their waiting time (WT) and cataract surgery outcome. Methods: A prospective cohort of consecutive patients waiting for cataract surgery were assessed by their ophthalmologist. Satisfaction, maximum acceptable waiting time (MAWT), urgency, visual function, visual acuity (VA), and health related quality of life (EQ-5D) were assessed using mailed questionnaires before surgery and 8–10 weeks after surgery. Ordinal logistic regression was used to build explanatory models. Results: 166 patients (61.9% female, mean age 73.4 years) had a mean WT of 16 weeks. Patients whose actual WT was shorter than their MAWT had greater odds of being satisfied with their WT than those whose WT was longer (adjusted OR 3.86, 95% CI 1.38 to 10.74). Improvement in visual function (OR 3.19, 95% CI 1.78 to 5.73), and VA (OR 4.27, 95% CI 1.70 to 10.68) significantly predicted satisfaction with surgery. Models were adjusted for age and sex. Conclusion: Patient perspectives on MAWT and satisfaction with WT are important inputs to the process of determining WT standards for levels of patient priority. Patient expectation of WT may mediate satisfaction with actual WT.

Background: The Western Canada Waiting List Project (WCWL) is a federally funded partnership of 19 organizations, including medical associations, health authorities, ministries of health and research organizations, that was created to develop tools to assist in the management of waiting lists. The WCWL cataract surgery panel, one of five panels constituted under this project, developed and tested a set of standardized clinical criteria for prioritizing among patients awaiting cataract surgery. Methods: The cataract surgery panel was composed of seven academic and community ophthalmologists, two family physicians, an optometrist, a health care services researcher and a health information specialist. The panel met three times between October 1999 and June 2000. The priority criteria were applied to 563 patients in the four western provinces. Regression analysis was used to determine the set of criteria weights that collectively best predicted clinicians' overall ratings of urgency. Interrater and test-retest reliability were assessed, based on clinicians' ratings of videotaped interviews with six hypothetical patients. Results: The resulting criteria accounted for about one-third of the observed variance in clinicians' ratings of overall clinical urgency (R 2 = 31.20. The panel modified the original criteria and weights based on empirical results and clinical judgement. Reliability of the revised criteria items was mixed, with the lowest reliability observed for items dealing with glare and social role. Interpretation: Participating clinicians considered the criteria easy to use and reasonably reflective of expert surgical judgement regarding clinical urgency. Further development and testing of the tool appear warranted.

Objective: To investigate the possibility that fasting is not required before cataract surgery. Study Design: Retrospective review. Participants: All patients who had cataract surgery alone (not combined with corneal or glaucoma surgery) at Mount St. Joseph Hospital between April 1, 2007, and March 31, 2008. Methods: Three methods were used to determine whether any cases of aspiration pneumonia after cataract surgery had occurred: recall by the supervising anaesthetist, a search of hospital medical records for admissions with a diagnosis of pneumonia, and recall by the operating surgeons. Results: In 5125 cases of cataract surgery, no case of aspiration pneumonia was found. Conclusions: This study suggests that it is safe to perform cataract surgery under topical or infiltration anaesthesia with intravenous sedation without fasting prior to surgery.
