ABSTRACT

PRCIS: Preserflo® surgery is a safe procedure, effective in reducing intraocular pressure into the "low teens", surgical survival is greatest in cases of high baseline intraocular pressure (above 21 mmHg) and when performed as a standalone procedure. PURPOSE: To evaluate midterm surgical survival and safety profile of Preserflo® filtering surgery. METHODS: Retrospective, cohort study. Consecutive patients who underwent standardized Preserflo® implantation with mitomycin C from December 2019 to April 2021 were included. Clinical data was retrieved from patient charts. Primary outcome was surgical survival at twenty-four months in accordance with World Glaucoma Association guidelines. Survival was evaluated using Kaplan-Meier statistics. Analysis was performed at eye-level and as intention-to-treat. RESULTS: Ninety-five eyes were included in this study (18 cases combined with cataract surgery). Over half of cases (n=51) were primary open angle glaucoma, with over a fifth having a prior filtering glaucoma procedure. Intraocular pressure at twenty-four months was significantly decreased from baseline (22.4±6.28 mmHg vs 12.0±3.43 mmHg), as well as the need for IOP-lowering medication (2.88 (±0.92) vs 0.79 (±1.3), P<0.001 all comparisons. Standalone Preserflo® achieved a qualified survival (irrespective of medication) of 71% (CI 95% 62%-83%) and 44% (CI 95% 27%-75%) in the combined procedure subgroup (P<0.05 when considering absolute survival). Eyes with baseline intraocular pressure ≥21 mmHg showed a greater qualified survival when compared to eyes with baseline ≤18 mmHg (80% (CI 95% 65%-100%) vs (50% (CI 95% 32%-76%; P<0.05). Intra and early operative complications were few, self-limited, and did not require surgical management. The reoperation rate was low (18%). CONCLUSION: Preserflo ® filtering surgery is effective in reducing intraocular pressure into the "low teens" and presents an adequate surgical survival and safety profile. Surgical survival appears greatest when performed as standalone and when pre-operative intraocular pressure is high (≥21 mmHg).

ABSTRACT

PURPOSE: This study describes the virtual clinic triage system implementation process at Hospital Santa Maria-Centro Hospitalar Universitário Lisboa Norte (HSM-CHULN) and analyzes its results regarding healthcare outcomes for the patients and the system. METHODS: A retrospective analysis was performed, comparing two cohorts (pre-virtual cohort; virtual triage cohort). Outcomes related to waiting time, number of hospital visits, decisions at first contact, and ancillary exam-based decisions were reported. RESULTS: Two hundred and ninety-two charts were reviewed (pre-virtual cohort: 132; virtual cohort: 160). Mean waiting time between referral and the first medical contact with the glaucoma department decreased on average by 71.3 days (human contact: 286.6 days; virtual triage contact: 215.3 days). Triage system significantly decreased waiting time for glaucoma patients, with an average decrease of 326.8 days between referral and treatment decision. Triage staging allowed to label 107 (66.9; 95% confidence intervals (CI): 59.6%, 74.2%) as non-urgent; 30 (18.8%; 95% CI: 12.7%, 24.9%) as urgent, and 23 (14.3%; 95% CI: 8.9%, 19.7%) as immediate contact, with the scheduling of future appointments reflecting National Institute for Health and Care Excellence (NICE) guidelines in every patient. Moreover, the number of visits to perform the same exams and obtain the same clinical decisions was reduced by 63.6%. CONCLUSION: Our virtual screening strategy significantly decreased waiting time, number of hospital visits, and increased chances of data-assisted clinical decision. While results can be further improved, this system can add value in an overburdened healthcare system, where triage systems with remote decision-making may be valuable tools in optimizing glaucoma care, even without allocation of extra resources.
