ABSTRACT

BACKGROUND: Retinal hemorrhages (RH) are a common manifestation of abusive head trauma (AHT) resulting from acceleration-deceleration injury with or without blunt impact. Evaluation of a child with RH requires careful consideration of these differential diagnoses. The extent to which coagulopathy alone can cause RH would be useful to understand as coagulopathy may accompany AHT. OBJECTIVE: In this systematic review, we sought to identify whether coagulopathies have been reported with RH similar to those of AHT. METHODS: We performed a literature search for ocular manifestations of bleeding disorders in children less than 18 years old. We included clotting factor deficiencies, vitamin K deficiency, platelet function abnormalities, thrombocytopenia, disseminated intravascular coagulation (DIC), and trauma induced coagulopathy (TIC). We included only pediatric reports of intraocular bleeding or documented eye examinations that indicated no hemorrhages. We then re-examined cases for ocular and systemic findings that could potentially mimic abuse. RESULTS: Our initial search yielded 816 results. Sixty-one articles met our inclusion criteria. Of these, there were 32 children within the AHT age range (less than 5 years old) who had RH and concomitant coagulopathy. Only 5 cases might potentially be confused for abuse. Of these, no classic characteristics of RH from abuse such as retinoschisis or retinal folds were found. Systemic features were inconsistent with AHT. CONCLUSIONS: The presence of coagulopathy alone does not rule out the possibility that the child has been abused. Coagulopathy alone has not been reported as an etiology of RH that are consistent with AHT, especially when other findings are present.

ABSTRACT

PRECIS: Gabapentin and its derivatives have numerous indications and are commonly prescribed medications. In this article, we provide evidence of a link between gabapentinoid use and incidence of acute angle-closure glaucoma. PURPOSE: Gabapentinoids, such as gabapentin and pregabalin, are commonly prescribed classes of drugs in North America. We sought to determine the association of gabapentin or pregabalin use and the incidence of acute angle-closure glaucoma. MATERIALS AND METHODS: This was a nested case-control study. All adult patients who developed acute angle-closure glaucoma between January 1, 2006 and December 31, 2016, and enrolled in the PharMetrics Plus database were eligible for inclusion. A conditional logistic regression model was constructed to assess the association between gabapentin or pregabalin use and the incidence of acute angle-closure glaucoma. RESULTS: Incidence of acute angle-closure glaucoma was found to be statistically significantly associated with the use of gabapentin in the year before diagnosis [relative risk (RR), 1.42; 95% confidence interval (CI), 1.00-2.00]. This association was not observed to be statistically significant with the current use of gabapentin (RR, 1.28; 95% CI, 0.77-2.12). Incidence of acute angle-closure glaucoma (AAG) was not found to be statistically significantly associated with either use of pregabalin in the year before diagnosis or current use (RR, 1.00; 95% CI, 0.51-1.93 and RR, 1.50; 95% CI, 0.66-3.38, respectively). CONCLUSIONS: To the best of our knowledge this is the first study to investigate the association between gabapentin or pregabalin use and the incidence of AAG. Gabapentin use in the year before diagnosis was found to be associated with the incidence of AAG.

ABSTRACT

PURPOSE: The purpose of this article is to determine the association of postoperative topical prostaglandin analog (PGA) or topical beta-blocker use and the incidence of pseudophakic cystoid macular edema (CME). METHODS: This was a nested case-control study. All adult patients who underwent cataract surgery between January 1, 2006 and December 31, 2016 and who were enrolled in the PharMetrics Plus database were eligible for inclusion. The association between postoperative topical PGAs (bimatoprost, latanoprost, and travoprost/travoprost-z) or beta-blocker (betaxolol, levobunolol, and timolol) use and the incidence of pseudophakic CME was assessed by conditional logistic regression. RESULTS: Five hundred eight cases and 5080 controls were included in the analyses. Incidence of pseudophakic CME was found to be statistically significantly associated with the current postoperative use of both topical PGAs [relative risk (RR), 1.86; 95% confidence interval (CI), 1.04-3.32] and topical beta-blockers (RR, 2.64; 95% CI, 1.08-6.49). Postoperative use of each of bimatoprost (RR, 2.73; 95% CI, 1.35%-5.53%) and travoprost/travoprost-z (RR, 3.16; 95% CI, 1.42-7.03) in the year before diagnosis was demonstrated to be statistically significantly associated with the incidence of pseudophakic CME. This association was not observed to be statistically significant with the postoperative use of latanoprost (RR, 1.55; 95% CI, 0.84-2.88). CONCLUSIONS: To the best of our knowledge this is the largest study that has investigated the association between postoperative topical PGA or topical beta-blocker use and the incidence of pseudophakic CME. Postoperative use of both topical PGAs and topical beta-blockers was found to be associated with the incidence of pseudophakic CME.

ABSTRACT

OBJECTIVE: The aim of this study was to document the use of eye personal protective equipment (PPE) by patients who had sustained an eye injury in the workplace and to evaluate the characteristics and outcomes of these patients. DESIGN: Case-control study. PARTICIPANTS: All adult patients who had sustained an eye injury in the workplace and presented to the urgent ophthalmology clinic of a tertiary care hospital from October 1, 2013, to November 30, 2014, were eligible for inclusion. METHODS: Medical records were reviewed to obtain occupational eye injury data, including etiology, type, and severity of injury as per the Ocular Trauma Score. Use of eye PPE at the time of injury was recorded. Outcome data, including disposition, duration of follow-up, and return to baseline best-corrected visual acuity, were also recorded. RESULTS: One hundred sixty-nine patients were included in this study. The median age of the cohort was 31 years (range, 17-68 years), and 92.9% were male. Chemical exposure (31.4%), grinding (17.9%), and injuries sustained by a sharp-object, metal, or nail (13.1%) were overall the most common etiologies of injury. Eye PPE was not worn by 66.9% of the cohort, with 33.1% of the cohort sustaining an occupational eye injury despite the use of eye PPE. CONCLUSIONS: Use of eye PPE among workers who sustain an eye injury in the workplace remains low; yet, its use does not preclude a significant proportion of such workers from injury. Increasingly advocating for both the use and appropriate selection of eye PPE in the workplace is an important public health initiative that should therefore be encouraged.

ABSTRACT

The objective of this randomized, controlled trial was to assess whether voluntary participation in a proctored, proficiency-based, virtual reality robotic suturing curriculum using the da Vinci(®) Skills Simulator™ improves robotic suturing performance. Residents and attending surgeons were randomized to participation or non-participation during a 5 week training curriculum. Robotic suturing skills were evaluated before and after training using an inanimate vaginal cuff model, which participants sutured for 10 min using the da Vinci(®) Surgical System. Performances were videotaped, anonymized, and subsequently graded independently by three robotic surgeons. 27 participants were randomized. 23 of the 27 completed both the pre- and post-test, 13 in the training group and 10 in the control group. Mean training time in the intervention group was 238 ± 136 min (SD) over the 5 weeks. The primary outcome (improvement in GOALS+ score) and the secondary outcomes (improvement in GEARS, total knots, satisfactory knots, and the virtual reality suture sponge 1 task) were significantly greater in the training group than the control group in unadjusted analysis. After adjusting for lower baseline scores in the training group, improvement in the suture sponge 1 task remained significantly greater in the training group and a trend was demonstrated to greater improvement in the training group for the GOALS+ score, GEARS score, total knots, and satisfactory knots.

ABSTRACT

BACKGROUND: Measuring the quality of surgical care is essential to identifying areas of weakness in the delivery of effective surgical care and to improving patient outcomes. Our objectives were to (1) assess the quality of surgical care delivered to adult patients; and (2) determine the association between quality of surgical care and postoperative complications. METHODS: This retrospective, pilot, cohort study was conducted at a single university-affiliated institution. Using the institution's National Surgical Quality Improvement Program database (2009-2010), 273 consecutive patients ≥18 years of age who underwent elective major abdominal operations were selected. Adherence to 10 process-based quality indicators (QIs) was measured and quantified by calculating a patient quality score (no. of QIs passed/no. of QIs eligible). A pass rate for each individual QI was also calculated. The association between quality of surgical care and postoperative complications was assessed using an incidence rate ratio, which was estimated from a Poisson regression. RESULTS: The mean overall patient quality score was 67.2 ± 14.4% (range, 25-100%). The mean QI pass rate was 65.9 ± 26.1%, which varied widely from 9.6% (oral intake documentation) to 95.6% (prophylactic antibiotics). Poisson regression revealed that as the quality score increased, the incidence of postoperative complications decreased (incidence rate ratio, 0.19; P = .011). A sensitivity analysis revealed that this association was likely driven by the postoperative ambulation QI. CONCLUSION: Higher quality scores, mainly driven by early ambulation, were associated with fewer postoperative complications. QIs with unacceptably low adherence were identified as targets for future quality improvement initiatives.

ABSTRACT

BACKGROUND: The ability to measure surgical quality of care is important and can lead to improvements in patient safety. As such, processes should be carried out in an identical fashion for all patients, regardless of how vulnerable or complex they are. Our objectives were to assess quality of surgical care delivered to elderly patients and to determine the association between patient characteristics and quality of care. STUDY DESIGN: This is a retrospective pilot cohort study, conducted in a single university-affiliated hospital. Using the institution's National Surgical Quality Improvement Program (NSQIP) database (2009 to 2010), 143 consecutive patients 65 years or older, undergoing elective major abdominal surgery, were selected. Adherence to 15 process-based quality indicators (QIs) was measured, and a pass rate was calculated for each individual QI. The association between patient characteristics (age, sex, Charlson Comorbidity Index, functional status, wound class) and patient quality score was assessed using multiple linear regression. RESULTS: Quality indicators with the lowest pass rates included postoperative delirium screening (0%), level of care documentation (0.7%), cognition and functional assessment at discharge (4.9%), oral intake documentation (12.6%), and pressure ulcer risk assessment (35.0%). The mean patient quality score was 46.8% ± 10.7% (range 16.7% to 75.0%). No association was found between patient characteristics and patient quality score. CONCLUSIONS: Quality of care delivered to elderly patients undergoing major surgery at our institution was generally poor and independent of patient characteristics. Although quality appears to be uniform across different patients, these results provide targets for quality improvement initiatives.
