Development of a rapid point-of-care patient reported outcome measure for cataract surgery in India

Implementation of PROMIS® in an Optometry Clinic

PURPOSE

The full utility of general health Patient-Reported Outcomes Measurement Information System® (PROMIS) surveys in the eye care setting has not been previously demonstrated. This report demonstrates the feasibility of implementing PROMIS in an eye care clinic.

PATIENTS AND METHODS

Over 2 months, general health and functioning PROMIS surveys were offered to all patients in an optometric clinic in Rochester, NY. Demographic and clinical variables were recorded along with percent completion and time to completion of the survey.

RESULTS

Across 651 patients, 258 chose to attempt PROMIS. Patients with low visual acuity were less likely to attempt the survey (p=0.049), and younger patients were more likely to complete the survey (p=0.025); no other patient characteristics were found to differ between those who did and did not participate in, nor complete, PROMIS. A total of 193 patients completed the survey (74.8%) in a mean time of 6.36 minutes (range = [1.43, 51.92] minutes; standard deviation = 5.62 minutes). Time to completion did not vary significantly across any groups.

CONCLUSION

Our relatively high completion rate among those who attempted PROMIS indicates that PROMIS surveys are feasible to implement in an optometry clinic. While most patients completed the survey in little time, the large range of time to completion may indicate that some patients had difficulty completing the survey. Furthermore, the significant difference in visual acuity between those who participated in the survey and those who did not highlights the need to address the way PROMIS is delivered in order to foster greater inclusion.

Validation and application of Catquest-9SF in various populations: A systematic review

Cataract is a common cause of reversible blindness. Visual acuity alone is not enough to assess appropriateness for surgery, prioritization, and outcomes. Catquest-9SF questionnaire evaluates patients' self-assessed visual function as related to daily tasks. We summarize and assess the validity of Catquest-9SF as a patient-reported outcome questionnaire to determine its suitability for clinical use. Thirteen studies with sample sizes ranging 102-10,886 (total n = 15,289) undertaken from 2009 to 2018 were included. Catquest-9SF showed unidimensionality, ordered response thresholds, and acceptable precision in all studies. Nine studies had significant mistargeting (range 0.66 to -2.04); the tasks being easy relative to the respondent ability in most studies. Two studies had misfitting items. We conclude Catquest-9SF is a valid and reliable tool to measure visual function in patients with cataract in various populations. Because results can be population specific, it is recommended that Catquest-9SF be validated in a new population before it is incorporated in routine practice.
