  4. Article ; Online: Treatment outcomes for amblyopia using PEDIG amblyopia protocols: a retrospective study of 877 cases.

    Buckle, Miranda / Billington, Catherine / Shah, Parth / Ferris, John D

    Journal of AAPOS : the official publication of the American Association for Pediatric Ophthalmology and Strabismus

    2019  Volume 23, Issue 2, Page(s) 98.e1–98.e4

    Abstract Background: The landmark Pediatric Eye Disease Investigators Group (PEDIG) Amblyopia Treatment Studies (ATS) 2A and 2B concluded that 6 hours of occlusion were as efficacious as full-time occlusion in treating severe amblyopia and that 2 hours occlusion were as effective as 6 in treating moderate amblyopia. We present the first retrospective study of real-world outcomes of amblyopia treatment using PEDIG amblyopia protocols in 877 patients treated at a single center.
    Methods: Electronic patient records were reviewed retrospectively to identify children meeting ATS2A (severe amblyopia) and ATS2B (moderate amblyopia) inclusion criteria who presented at the Gloucestershire Eye Unit from 2013 to 2017. Clinical data for each patient were entered during routine clinical care. Severely amblyopic children were prescribed 6 hours occlusion daily, and moderately amblyopic children 2 hours, after 12 weeks refractive adaptation.
    Results: A total of 288 children were in the ATS2A group and 589 in the ATS2B group. Of the severely amblyopic eyes, 40% achieved best-corrected visual acuity better than 0.4 logMAR at 32 weeks, increasing to 55% at 48 weeks; of the moderately amblyopic eyes, 71% achieved best-corrected visual acuity better than 0.3 logMAR at 32 weeks. The mean number of lines of visual improvement was 4.2 for severely amblyopic eyes and 2.1 for moderately amblyopic eyes.
    Conclusions: This is the largest reported series of amblyopia treated according to PEDIG protocols. The study population achieved outcomes comparable to those demonstrated by the PEDIG studies. This audit represents a "real-world" benchmark for treatment outcomes in clinical practice.

    Abstract Objective: To investigate the impact of EyeSi surgical simulators on posterior capsule rupture (PCR) rates of cataract surgery performed by first and second year trainee surgeons.
    Design: A Royal College of Ophthalmologists' National Ophthalmology Database audit study of first and second year surgeons' PCR rates over seven consecutive National Health Service (NHS) years. Participating centres were contacted to ascertain the date when their surgeons had access to an EyeSi machine and whether this was on-site or off-site. Operations were classified as before, after or no access to EyeSi.
    Setting: The study took place in 29 NHS Ophthalmology Units in a secondary care setting.
    Results: Two-hundred and sixty five first and second year trainee surgeons performed 17 831 cataract operations. 6919 (38.8%) operations were performed before access to an EyeSi, 8648 (48.5%) after access to an EyeSi and 2264 (12.7%) operations by surgeons with no access to an EyeSi. Overall, there was a 38% reduction in the first and second year surgeon's unadjusted PCR rates from 4.2% in 2009 to 2.6% in 2015 for surgeons with access to an EyeSi, and a 3% reduction from 2.9% to 2.8% for surgeons without access to an EyeSi. The overall first and second year unadjusted PCR rates for before, after and no access to EyeSi were 3.5%, 2.6% and 3.8%, respectively. The decrease in the with-access to an EyeSi group PCR rate was similar for surgeons with access to an EyeSi 'on site' or 'off site'.
    Conclusions: First and second year trainee surgeons' unadjusted PCR rates have decreased since 2009 which has significant benefits for patients undergoing cataract surgery. This 38% reduction in complication rates aligns with the introduction of EyeSi simulator training.

    Abstract Purpose: To evaluate the cost-effectiveness of phacoemulsification simulation training in virtual reality simulator and wet laboratory on operating theater performance.
    Methods: Residents were randomized to a combination of virtual reality and wet laboratory phacoemulsification or wet laboratory phacoemulsification. A reference control group consisted of trainees who had wet laboratory training without phacoemulsification. All trainees were assessed on operating theater performance in 3 sequential cataract patients. International Council of Ophthalmology Surgical Competency Assessment Rubric-phacoemulsification (ICO OSCAR phaco) scores by 2 masked independent graders and cost data were used to determine the incremental cost-effectiveness ratio (ICER). A decision model was constructed to indicate the most cost-effective simulation training strategy based on the willingness to pay (WTP) per ICO OSCAR phaco score gained.
    Results: Twenty-two trainees who performed phacoemulsification in 66 patients were analyzed. Trainees who had additional virtual reality simulation achieved higher mean ICO OSCAR phaco scores compared with trainees who had wet laboratory phacoemulsification and control (49.5 ± standard deviation [SD] 9.8 vs 39.0 ± 15.8 vs 32.5 ± 12.1, P < .001). Compared with the control group, ICER per ICO OSCAR phaco of wet laboratory phacoemulsification was $13,473 for capital cost and $2209 for recurring cost. Compared with wet laboratory phacoemulsification, ICER per ICO OSCAR phaco of additional virtual reality simulator training was US $23,778 for capital cost and $1879 for recurring cost. The threshold WTP values per ICO OSCAR phaco score for combined virtual reality simulator and wet laboratory phacoemulsification to be most cost-effective was $22,500 for capital cost and $1850 for recurring cost.
    Conclusions: Combining virtual reality simulator with wet laboratory phacoemulsification training is effective for skills transfer in the operating theater. Despite of the high capital cost of virtual reality simulator, its relatively low recurring cost is more favorable toward cost-effectiveness.

    Abstract Objective: This paper reviews the experience of penetrating chest trauma over a 3-year period in one UK emergency department.
    Methods: A retrospective review was performed of patients assessed in the emergency department resuscitation room between 1 January 2002 and 31 December 2005. Patients with penetrating chest trauma, either isolated or in combination with other injuries, were included. A Medline search was performed using the terms 'chest', 'trauma' and 'penetrating'.
    Results: A total of 120 patients presented with penetrating chest trauma. Ninety-two percent were male. Ninety-six percent (115) of the patients survived to hospital discharge. Seventy-eight percent of the patients presented at night (20.00 and 8.00 h). A single wound accounted for 52% (63) of patients, multiple wounds 43% (52) with 2% (two) gun-shot wounds and 3% (three) impalings. The mean prehospital time of patients in cardiac arrest was 42 min with a mean on-scene time of 24 min. The mean prehospital time for patients undergoing formal emergency surgery was 39 min with a mean on-scene time of 16 min. Twenty-three patients required one or more tube thoracostomies to be performed in the emergency department and six underwent emergency department thoracotomy. Sixteen patients required immediate formal emergency surgery for haemorrhage control.
    Conclusion: Penetrating chest trauma contributes significantly to our trauma workload with a high proportion of patients sustaining life-threatening injuries requiring immediate intervention. Significant prehospital delays occur. Overall mortality of 4.2% is comparable with that of a major American case series. Further education and protocol development is required to ensure that prehospital and emergency department management of these patients reflects the latest evidence-based guidelines.
