Barriers to hand hygiene in ophthalmic outpatients in Uganda: a mixed methods approach.

BACKGROUND: Healthcare-associated infection rates are high in low-income countries and are associated with significant morbidity. There is a paucity of published data on infection control practice, attitudes or resources in these settings, particularly in ophthalmology. The aim of this study is to understand current hand washing practices, barriers to hand washing and facilities available in two Ugandan specialist eye hospitals. This study was undertaken through non-participant observations of healthcare worker hand washing practices, documentation of hand hygiene facilities and semi-strucutured interviews with clinical staff. RESULTS: Eighty percent of the WHO opportunities for hand washing were missed through lack of attempted hand hygiene measures. Facilities for hand hygiene were inadequate with some key clinical areas having no provisions for hand hygiene. Training on effective hand hygiene varied widely with some staff reporting no training at all. The staff did not perceive the lack of facilities to be a barrier to hand washing but reported forgetfulness, lack of time and a belief that they could predict when transmission might occur and therefore did not wash hands as often as recommended. CONCLUSIONS: Hand hygiene at the two observed sites did not comply with WHO-recommended standards. The lack of facilities, variable training and staff perceptions were observable barriers to effective hand hygiene. Simple, low-cost interventions to improve hand hygiene could include increased provision of hand towels and running water and improved staff education to challenge their views and perceived barriers to hand hygiene

Improving quality by improving safety

Protecting patients from harm is one of the most important things health professionals can do for their patients. However, an estimated 1 in 10 patients are harmed while receiving hospital care in high-income countries,1 and studies suggest that the rates of harm are higher in low- and middle-income countries.2 The World Health Organization (WHO) describes safety as a key dimension of quality health care

Efficacy and Safety of the Ab-interno Xen Gel Stent After Failed Trabeculectomy.

AIMS: To assess the efficacy and safety of the Xen gel stent in reducing intraocular pressure (IOP) in eyes with prior failed trabeculectomy and to determine the frequency of complications and further intervention. METHODS: Retrospective case note review of all patients with prior trabeculectomy undergoing Xen surgery across 5 centers from August 2015 to May 2017. RESULTS: In total, 17 surgeries were reviewed. IOP reduced from 21.5 (±2.4) mm Hg preoperatively to 13.6 (±3.4) mm Hg at month 12 (P<0.05). Medication usage reduced from 2.8 (±0.6) preoperatively to 1.0 (±1.3) at month 12 (P<0.05). Adverse events included: numerical hypotony (IOP<6 mm Hg) in 4 cases (23.5%) that all resolved spontaneously, IOP spike of ≥30 mm Hg in 2 (11.8%) cases and transient occlusion of the implant by iris in 1 (5.9%) case. Secondary filtration surgery (Baerveldt tube implantation) was required in 2 (11.8%) cases. Postoperative bleb intervention was required in 9 cases (52.9%), usually in the first month after surgery. CONCLUSIONS: Xen reduces IOP and number of medications in eyes with failed trabeculectomy. Detailed preoperative conjunctival assessment and targeted stent placement is required. Prospective data and follow-up beyond 12 months are required but Xen seems a viable, effective, and safe option after failed trabeculectomy

Recommendations for the management of elevated intraocular pressure due to bleb fibrosis after XEN gel stent implantation

Surgical management of glaucoma offers a means of effective disease control. A gel stent that facilitates drainage to the subconjunctival space offers intraocular pressure (IOP) reduction similar to traditional glaucoma filtering surgeries in a less invasive manner. However, like all subconjunctival filtering procedures that result in a bleb, fibrosis can present as a cause of elevated IOP. The following proposed techniques and recommendations for managing elevated IOP due to bleb fibrosis after gel stent implantation are based on the clinical experience of the authors. The goal of this paper is to improve outcomes following gel stent surgery by providing guidance on assessment of bleb function and strategies for bleb enhancement.status: publishe

Teaching referral skills to medical students

BACKGROUND: Referrals are an important and frequent part of a junior doctor’s work. Difficulty with making successful referrals is also very common. Despite this, training in referral skills is not routinely carried out in medical schools. RESULTS: We designed and delivered a 1-h interactive lecture to final year medical students to teach referral skills. The lecture was delivered on six occasions to up to 70 students at each session. 191 students attended and provided evaluation. 68 % of students had no previous training in referral skills and 99 % felt that referral skills should be included in the undergraduate curriculum. 90 % reported that the lecture had improved their understanding of referral techniques and 83 and 80 % felt that the lecture had improved their ability and confidence, respectively. CONCLUSIONS: Referral skills can be successfully taught in a large group lecture setting. We recommend that the teaching of referral skills is incorporated into all medical schools’ curricula

The Royal College of Ophthalmologists' National Ophthalmology Database Study of Cataract Surgery: report 11, Techniques and Complications of Local Anaesthesia for Cataract Surgery in the United Kingdom.

PURPOSE: To describe variation in local anaesthesia techniques and complications over a 10-year period for cataract surgery in the United Kingdom. SETTING: Reporting centres to the Royal College of Ophthalmologists (RCOphth) National Ophthalmology Database (NOD). DESIGN: Retrospective cross-sectional register-based study. METHODS: Data from the RCOphth NOD was used. Eligible for analysis were 1195882 cataract operations performed using local anaesthesia between 01/04/2010 and 31/03/2020 in 80 centres. RESULTS: Overall, topical anaesthesia alone was used in 152321 (12.7%) operations, combined topical and intracameral in 522849 (43.7%), sub-Tenon's in 461175 (38.6%), and peribulbar/retrobulbar in 59537 (5.0%). In National Health Service (NHS) institutions, 48.3% operations were topical with/without intracameral vs 88.7% in independent sector treatment centres (ISTC). 45.9% were sub-Tenon's in NHS vs 9.6% in ISTC. 5.8% were peribulbar/retrobulbar in NHS vs 1.7% in ISTC. Anaesthetic complication rates decreased from 2.7% in the 2010 NHS year to 1.5% in the 2019 NHS year (overall, 2.1% for NHS; 0.2% for ISTC). Overall anaesthetic complication rates were 0.3%, 0.3%, 3.5% and 3.1% for topical alone, combined topical/intracameral, sub-Tenon's and peribulbar/retrobulbar respectively. Complication rates were higher for sharp needle anaesthesia (peribulbar/retrobulbar) in patients taking warfarin rather than direct oral anticoagulants (4.8% vs 3.1%; p= 0.024). Considerable variation was observed between centres on anaesthetic choices and anaesthetic complication rates. CONCLUSIONS: Combined topical and intracameral is the most common choice of anaesthesia for cataract surgery in the United Kingdom and is associated with lower anaesthetic-related complication rates than sub-Tenon's and peribulbar/retrobulbar anaesthesia. Variation in anaesthetic choice exists between centres and between NHS & ISTC sectors

The Royal College of Ophthalmologists' National Ophthalmology Database Study of Cataract Surgery: Report 12, Risk factors for suprachoroidal haemorrhage during cataract surgery

OBJECTIVE: To establish the incidence of acute intraoperative suprachoroidal haemorrhage (AISH) during cataract surgery and identify the risk factors for this complication. METHODS: Data from the Royal College of Ophthalmologists' National Ophthalmology Database was analysed. During the 11-year study period, from 01/04/2010 to 31/03/2021, 709 083 operations performed on 498 170 patients from 65 centres were eligible for inclusion. RESULTS: AISH occurred in 0.03% (204/709 083, approximately 1 in 3 500) of eligible cataract operations performed during the study period. Posterior capsule rupture was the risk factor most strongly associated with AISH (OR: 17.6, 95% CI: 12.4-24.9, p < 0.001). Other ocular risk factors identified were raised intraocular pressure (IOP) preoperatively (OR: 3.7, 95% CI: 2.5-5.5, p < 0.001), glaucoma (OR: 1.7, 95% CI: 1.2-2.4, p = 0.004). Risk increased with age and patients aged over 90 years were at greatest risk (OR: 6.7, 95% CI: 3.5-12.8, p < 0.001). The addition of intracameral anaesthetic when performing surgery under topical anaesthetic appears to be protective (OR: 0.5, 95% CI: 0.3-0.8, p = 0.003), compared to topical anaesthetic alone. There was a 16-fold increase in the incidence of vision loss when AISH occurred. CONCLUSIONS: The risk of AISH during modern cataract surgery is approximately 1 in 3 500 and is associated with a significant increase in the risk of vision loss should it occur. Posterior capsule rupture is the risk factor most strongly associated with AISH. Preoperative IOP control is a modifiable risk factor. The use of intracameral anaesthesia may reduce the risk of AISH
