Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The Best Practice Surgical and Refractive (BRIGhT) management strategy for cataract, which combines expedited sequential cataract surgery within 3 months of assessment (consistent with draft Cataract Clinical Care Standard) at either Sydney Eye Hospital or Westmead Hospital and provision of necessary refractive correction through updated spectacle lenses within 2 weeks of second eye surgery. The proposed intervention has been developed based on evidence for the benefits of timely cataract surgery, benefits of operating on both eyes, and the knowledge that post-operative spectacle updates are commonly required. The cataract surgeries will be completed by a hospital staff ophthalmologist and spectacle updates by a community optometrist. Whether any required updates to spectacles has been completed will be known through the record of redemption of the spectacle update voucher. At the follow-up visit where the study participant's spectacles will be measured to confirm the nature of the update to the spectacles. The cataract surgery dates will be extracted from the medical records and reviewed to determine if expedited cataract surgery was successfully delivered in the intervention group and that the control group joined the waiting list and access first eye surgery as expected within 365 days.
Intervention code [1] 312777 0
Treatment: Other
Comparator / control treatment
The control group is the patient receiving standard care with usual waiting time for the second eye cataract surgery. It is likely that patient receive standard care (control group) will only receive first eye surgery during the 12-month enrolment period due to current waiting times at the two public hospital sites.

Outcomes
Primary outcome [1] 307929 0
Number of falls over 12 months following randomisation, based on prospective, self-reporting by monthly falls calendars
Timepoint [1] 307929 0
Falls will be recorded prospectively for 12 months using monthly calendars with active follow-up
Secondary outcome [1] 353370 0
The EuroQual EQ-5D-5L will be used to assess quality of life and is a standard instrument found to be able to measure the impact of falls, independent of chronic conditions.
Timepoint [1] 353370 0
12 months after randomisation
Secondary outcome [2] 353371 0
The effect on visual disability (using Catquest 9-SF)
Timepoint [2] 353371 0
6 months and 12 months after randomisation
Secondary outcome [3] 353468 0
The effect on physical activities (using Incidental & planned exercise questionnaire)
Timepoint [3] 353468 0
6 months and 12 months after randomisation
Secondary outcome [4] 353469 0
The effect on depression symptoms (geriatric depression scale)
Timepoint [4] 353469 0
6 months and 12 months after randomisation
Secondary outcome [5] 353898 0
A comprehensive economic evaluation incorporating cost-effectiveness and cost-utility analyses will be conducted from a health service provider perspective. A trial based economic analysis will be completed using the EuroQual EQ-5D-5L to estimate effectiveness of the intervention. Data on total health care costs and fall-related health care costs will enable assessment of the within–trial cost-effectiveness of the program.

Key exclusion criteria
Participants will be excluded if they have a diagnosis of dementia, Parkinson’s Disease or stroke, are wheelchair bound, have significant ocular comorbidities (advanced glaucoma, retinopathy or amblyopia), are scheduled for combined ocular surgery (e.g. cataract and glaucoma), reside outside the metropolitan area, or are otherwise unable to participate in the follow-up assessments.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The randomisation sequence will be generated by an investigator not directly involved in participant recruitment or data entry for falls calendars. This sequence will be uploaded into the on-line database and the randomisation enabled after completion of the baseline assessment. To minimise observational bias, the research assistants conducting the 6- and 12-month assessments will be masked to group allocation. It is not possible to mask the participants to the type of intervention.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Group allocation will be determined using an on-line randomisation process (REDCap).

Efficacy
Statistical methods / analysis
The number of falls per person-year will be analysed using negative binomial regression to estimate the difference in falls rates between the two groups. The proportion of fallers and recurrent fallers between groups will be compared using the relative risk statistic. Pre-specified sub-group analyses include previous multiple fallers, degree of vision loss and self-reported and objectively measured physical activity. An intention-to-treat approach will be used for all primary analyses. The relationship between the measures of process and the trial outcomes will be investigated using multivariate negative binomial regression with the count of falls as the outcome measure and interactions will be explored. A statistical analysis plan will be published before database lock. Quantitative analyses will be conducted using SAS and STATA software packages.
