Clinical Relevance: Realistic benchmarks can serve as comparators for optometrists wishing to engage in clinical practice audits of their glaucoma care.

Background: The iCareTrack study established the appropriateness of glaucoma care delivery through clinical record audits of Australian optometry practices. Benchmarks required for monitoring and improving glaucoma care delivery do not exist.

Clinical Relevance: Valid and updated clinical indicators can serve as important tools in assessing and improving eyecare delivery.

Background: Indicators for diabetic eyecare in Australia were previously developed from guidelines published before 2013 and then used to assess the appropriateness of care delivery through a nationwide patient record card audit (the iCareTrack study). To reflect emerging evidence and contemporary practice, this study aimed to update clinical indicators for optometric care for people with type 2 diabetes in Australia.

Background: After an intensive care unit (ICU) admission, nearly 20% of survivors of chronic critical illness require admission to a long-term acute care hospital (LTACH) for continued subspecialty care. The effect of the burden of medical comorbidities on discharge disposition after LTACH admission remains unclear.

Methods: A retrospective cohort study was performed involving patients with chronic critical illness who were discharged from the medical ICU and admitted to an LTACH between 2016 and 2018.

Background: High venous thromboembolism (VTE) rates have been described in critically ill patients with COVID-19. We hypothesized that specific clinical characteristics may help differentiate hypoxic COVID-19 patients with and without a diagnosed pulmonary embolism (PE).

Methods: We performed a retrospective observational case-control study of 158 consecutive patients hospitalized in one of four Mount Sinai Hospitals with COVID-19 between March 1 and May 8, 2020, who received a Chest CT Pulmonary Angiogram (CTA) to diagnose a PE.

Purpose: Currently, there are no UK optometric guidelines regarding the pre and postoperative refractive management of patients undergoing cataract surgery. This study used a Delphi method to gain consensus on best practice.

Methods: Eighteen recommendations targeted areas of concern/variability in advice that were highlighted in an earlier focus group study of refractive management for patients who had received cataract surgery.

Background: Age-related macular degeneration, a prevalent degenerative retinal disease, is associated with non-visual and psychosocial impairments that may affect sleep. In this systematic review, we evaluated associations between age-related macular degeneration (AMD) and sleep, highlighted knowledge gaps and provided evidence-based recommendations to clinicians to enable holistic management of AMD patients.

Methods: We searched PubMed, Embase and the Cochrane Central registries for papers published before May 2022.

Predictive models for key outcomes of coronavirus disease 2019 (COVID-19) can optimize resource utilization and patient outcome. We aimed to design and internally validate a web-based calculator predictive of hospitalization and length of stay (LOS) in a large cohort of COVID-19-positive patients presenting to the Emergency Department (ED) in a New York City health system. The study cohort consisted of consecutive adult (> 18 years) patients presenting to the ED of Mount Sinai Health System hospitals between March 2020 and April 2020, diagnosed with COVID-19.

Objective: To compare fall incidence, and visual acuity and refractive status, before surgery and after first and second eye cataract surgery.

Design, Setting: Prospective observational study in eight tertiary referral ophthalmology clinics in public hospitals in Sydney, Melbourne, and Perth.

Participants: People aged 65 years or more referred for bilateral age-related cataract surgery during 2013-16, followed for maximum of 24 months after study entry or until six months after second eye surgery, whichever was shorter.

Background: Data on long-term outcomes of catheter ablation (CA) for atrial fibrillation (AF) in outside of clinical trials settings are sparse.

Objective: We aimed to assess outcomes and readmissions at 1 year following admission for CA for AF.

Methods: Utilizing the Nationwide Readmissions Database (2016-2018), we identified patients with CA among all patients with a primary admission diagnosis of AF, and a control group by propensity score match adjusted for age, sex, comorbidities, CHA₂DS₂-VASc scores, and the hospital characteristics.

Sensory impairments and sarcopenia are both highly prevalent age-related conditions, with the former having been postulated to contribute to the pathogenesis of the latter condition. Confirming this hypothesis may therefore help to better inform strategies for early treatment and intervention of sarcopenia. We performed a systematic review of the current literature examining the relationships between four major sensory impairments [vision (VI), hearing (HI), smell (SI), and taste (TI)] with (i) sarcopenia; and (ii) its associated components (low handgrip strength, slow gait speed, and low muscle mass).

Clinical Relevance: Current levels of appropriateness for primary diabetic eyecare delivered by Australian optometrists are presented along with realistic targets (benchmarks) for quality improvement. The demonstrated methods can be used in practice evaluation and benchmarking of other clinical practice areas and settings.

Background: To examine the appropriateness of diabetic eye-care delivery and establish achievable benchmarks of care (ABCs) for optometry practices in Australia.

Significance: This study provides guidance for the implementation of recommendations for falls prevention in optometry practice, through synthesis with the optometrists' viewpoint as a major stakeholder. Educators and clinicians can adopt the revised recommendations and associated implementation strategies in this research for successful integration into optometric practice.

Purpose: Recommendations for optometrists to help prevent falls in older patients were published in 2019 by Optometry Australia.

Background Despite advances in resuscitation medicine, the burden of in-hospital cardiac arrest (IHCA) remains substantial. The impact of these advances and changes in resuscitation guidelines on IHCA survival remains poorly defined. To better characterize evolving patient characteristics and temporal trends in the nature and outcomes of IHCA, we undertook a 20-year analysis of a national database.

Purpose: We are developing an age-related macular degeneration (AMD) health-related quality of life (HRQoL) item bank, applicable to Western and Asian populations. We report primarily on content generation and refinement, but also compare the HRQoL issues reported in our study with Western studies and current AMD-HRQoL questionnaires.

Methods: In this cross-sectional, qualitative study of AMD patients attending the Singapore National Eye Centre (May-December 2019), items/domains were generated from: (1) AMD-specific questionnaires; (2) published articles; (3) focus groups/semi-structured interviews with AMD patients (n = 27); and (4) written feedback from retinal experts.
