A comparison of daytime and out of hour mental health presentations to Beaumont Hospital Emergency Department between 2018 and 2020.

BACKGROUND: In 2018, there were more than 12,000 self-harm presentations to emergency departments (EDs) in Ireland with 50% occurring between 7p.m. and 3a.m. There is evidence that the assessment quality and follow-up is variable across clinicians. To address this, The National Clinical Programme for the Management of Self-Harm in the ED (NCPSH 2016) was developed to set clear standards. AIM: Our aim was to compare diagnosis and management of patients presenting to Beaumont Hospital (BH) ED, across a 3-year period, by the on-site Liaison Psychiatry Service, during normal working hours, to the off-site on call service outside of normal working hours (OOH). METHODS: This is a retrospective audit of BH ED patients referred for psychiatric assessment between 2018 and 2020, using patient electronic records for data collection, and Pearson's chi square testing for group differences. Post hoc analysis was performed using adjusted residuals and Bonferroni correction. RESULTS: Of 3659 psychiatric referrals to Beaumont ED from 2018 to 2020, alcohol-related disorders were the most common diagnosis and were diagnosed more frequently during normal working hours (n = 592, 16.2%; 22.9% normal hours vs 8.5% OOH, p < 0.001), while personality disorder was diagnosed more frequently out of hours. (n = 432, 11.8%; 9.6% normal hours vs 14.4% out of hours, p < 0.001). There was a statistically significant difference in referral to voluntary services out of hours (7.2% normal hours vs 0.3% OOH). CONCLUSION: In contrast to previous findings, our study found higher rates of alcohol-related disorders diagnosed during normal hours vs OOH. Furthermore, voluntary and addiction services were under-utilised OOH and this presents an important teaching opportunity.

Impact of Ophthalmic Viscosurgical Devices in Cataract Surgery.

BACKGROUND: Ophthalmic viscoelastic devices (OVDs) used during small-incision cataract surgery have numerous advantages. However, OVDs have longer retention time in an eye after surgery resulting in intraocular pressure (IOP) spikes. The purpose of this study is to analyze and quantify the effect of various OVDs on both IOP and best corrected visual acuity (BCVA) by systematically reviewing the literature and performing meta-analysis. METHODS: Numerous databases from January 1, 1985, to present were systematically searched. Thirty-six (3893 subjects) of 3313 studies identified were included for analysis. Standardized mean difference (SMD) was computed, and meta-analysis was performed. RESULTS: A total of 3313 records were retrieved including 1114 from database search and 2199 from grey literature search. Significant increase in postoperative IOP in 1-day follow-up with Healon (SMD = 0.37, CI: [0.07, 0.67]), Viscoat (SMD = 0.29, CI: [0.13, 0.45]), Provisc (SMD = 0.46, CI: [0.17, 0.76]), and Soft Shell (SMD = 0.58, CI: [0.30, 0.86]) was computed. On the other hand, results implied a nonsignificant increase in postoperative IOP with Healon GV (SMD = 0.07, CI: [-0.28, 0.41]), Healon5 (SMD = 0.15, CI: [-0.33, 0.64]), 2% HPMC (SMD = 0.32, CI: [-0.0, 0.64]), and OcuCoat (SMD = 0.26, CI: [-0.37, 0.9]). Additionally, a nonsignificant reduction in postoperative IOP was inferred with Viscoat + Provisc (SMD = -0.28, CI: [-2.23, 1.68]). CONCLUSION: Improvement in IOP was shown with Viscoat + Provisc. Additionally, IOP nonsignificant upsurge was observed with Healon GV, Healon5, 2% HPMC, and OcuCoat compared to significant upsurge with Healon, Viscoat, and Soft Shell.
