Treatment rate of strabismus and amblyopia is associated with the location of pediatric ophthalmologists in the United States.

PURPOSE: To determine whether the geographic density of pediatric ophthalmologists is associated with the rate of children treated for strabismus and amblyopia. METHODS: This cross-sectional study included children treated for strabismus and amblyopia 0-17 years of age with commercial insurance who were included in the Vision and Eye Health Surveillance System. Additionally, pediatric ophthalmologists by state were determined using the American Association for Pediatric Ophthalmology and Strabismus website. Unadjusted linear regression was used to compare the geographic density of pediatric ophthalmologists and the rate of children treated for strabismus and amblyopia by state in 2016. This was repeated using multivariable linear regression, controlling for race, poverty, non-English-speaking children, and insurance coverage for children by state. RESULTS: New York and Mississippi had the highest and lowest rates of treatment of strabismus and amblyopia, with 3.97 and 0.83 children treated per 100 children, respectively. The geographic density of pediatric ophthalmologists was associated with the rate of children treated for strabismus and amblyopia in unadjusted analyses (ß = 0.62, P < 0.001). Further, the geographic density of pediatric ophthalmologists was associated with the rate of children treated for strabismus and amblyopia in adjusted analyses (ß = 0.61, P < 0.001). CONCLUSIONS: The geographic density of pediatric ophthalmologists by state was positively associated with the rate of children treated for strabismus and amblyopia.

Lessons Learned on a High-Altitude Expedition to Mount Kilimanjaro.

High-altitude expeditions expose teams to particular medical, environmental, and social challenges that can have unintended and severe consequences for crew members. In June 2017, the 9-d Equal Playing Field (EPF) expedition to Mount Kilimanjaro to set a world record for the highest-altitude soccer match ever played demonstrated the variety of challenges that may arise during these types of trips. This trip included a full-length soccer match at 5714 m (18,746 ft), leading to additional challenges for expedition members participating in the athletic event. The EPF medical team identified the challenges that occurred during the expedition and documented the methods used to resolve these challenges in real time. From the challenges faced during the expedition, we describe the lessons learned for future expeditions to Mount Kilimanjaro and other high-altitude environments. Challenges arose with medical tent visibility, medical disqualification, underreporting of medical events, and acute pain management, while anticipated challenges with interpersonal conflict did not occur. The rigorous preparation and anticipation by the EPF medical team prior to expedition departure may have helped mitigate this conflict as well as prevented unintended severe medical events from occurring.

Evaluating Discrepancies in Self-Reported Glaucoma and Electronic Health Records in the National Institutes of Health All of Us Database.

PURPOSE: Patient understanding of glaucoma diagnosis is critical for disease management and it is unclear if there are racial/ethnic differences in this regard. The purpose of this study was to determine the level of agreement between glaucoma diagnosis by self-report and electronic health record (EHR) data using the National Institute of Health's "All of Us (AoU)" database and to examine the association between race/ethnicity and discordance of glaucoma diagnosis between self-report and EHR data. DESIGN: Cross-sectional study. PARTICIPANTS: Individuals in AoU who answered a survey question about glaucoma diagnosis and had EHR data availability. METHODS: The agreement between self-reported glaucoma and EHR data was estimated using Cohen's κ coefficient. Multivariable logistic regression was performed, adjusting for age, sex, education level, income, and health care literacy, to examine the associations between race/ethnicity and discordance between self-reported glaucoma and EHR diagnosis. MAIN OUTCOME MEASURES: Agreement between self-reported glaucoma and EHR diagnosis. RESULTS: Of all 87 782 individuals, 1985 (2.26%) had both self-reported and EHR glaucoma, 81 781 (92.16%) had no glaucoma, 2022 (2.31%) individuals had EHR-only glaucoma, and 1994 (2.27%) had self-report-only glaucoma (Cohen's κ = 0.47). In the multivariable regression, Black or African American (adjusted odds ratio [aOR], 1.67; 95% confidence interval [CI], 1.40-1.98), Asian (aOR, 2.63; 95% CI, 1.97-3.44), and Hispanic or Latino (aOR, 1.63; 95% CI, 1.33-1.99) individuals were more likely to have EHR-only glaucoma than White individuals. Additionally, Black or African American (aOR, 2.30; 95% CI, 1.97-2.67) and Hispanic or Latino individuals (aOR,1.47; 95% CI, 1.21-1.79) were more likely to have self-report-only glaucoma compared with White individuals. CONCLUSIONS: In the AoU database, we found that Black or African American and Hispanic or Latino individuals had higher odds of discordance between glaucoma diagnosis by self-report and EHR. Future studies are needed to examine the issues leading to this discordance, such as a lack of patient understanding regarding their diagnosis or a lack of culturally appropriate physician explanation/teaching.

State Gun Regulations and Reduced Gun Ownership are Associated with Fewer Firearm-Related Suicides Among Both Juveniles and Adults in the USA.

BACKGROUND: Few studies have investigated the relationship between specific gun regulations and gun ownership with the firearm-related suicide rate among juveniles and adults across U.S. states. Therefore, this study seeks to determine if gun ownership rates and gun restrictions are related to the firearm-related suicide rate in both the pediatric and adult populations. METHODS: Fourteen measures of state gun law restrictions and gun ownership were collected. These included Giffords Center ranking, gun ownership percentages, and 12 specific firearm laws. Unadjusted linear regressions modeled the relationship between each individual variable and the rate of firearm-related suicides for adults and children across states. This was repeated using a multivariable linear regression adjusting for poverty, poor mental health, race, gun ownership, and divorce rates by state. P values of <0.004 were considered significant. RESULTS: In the unadjusted linear regression, 9 of 14 firearm-related measures were statistically associated with fewer firearm-related suicides in adults. Similarly, 9 of 14 measures were found to be associated with fewer firearm-related suicides in the pediatric population. In the multivariable regression, 6 of 14 vs. 5 of 14 measures were statistically associated with fewer firearm-related suicides in the adult and pediatric populations, respectively. CONCLUSIONS: Ultimately, this study found that increased state gun restrictions and lower gun ownership rates were associated with fewer firearm related suicides among juveniles and adults in the US. This paper provides objective data to help lawmakers as they create gun control legislation that can potentially decrease the rate of fire-arm related suicide. LEVELS OF EVIDENCE: II.

An Assessment of the Relationship Between BMI and Children Undergoing Surgical Procedures: A Retrospective Study.

Background: While multiple studies have documented that obesity increases the risk of operative complications among adults, little data exist on how obesity impacts surgical outcomes among children. We aimed to determine if children with obesity have different postoperative outcomes than their peers. Methods: A retrospective chart review was conducted of 875 patients aged between 2 and 18 years who underwent surgery during 2018. Patients were stratified, based on BMI percentile for age, as having less than healthy weight (<5th percentile), healthy weight (5th-84th percentile), excess weight (85th-94th percentile), or obesity (≥95th percentile). Demographic information and data on medical comorbidities and postoperative complications were collected. All analyses were conducted using chi-square or Kruskal-Wallis testing. Results: Eighty-two patients were excluded due to lack of BMI data and 56 were excluded as they had below healthy weight. Of the remaining 737 patients, 475 (64.4%) had healthy weight, 124 (16.8%) had excess weight, and 138 (18.70%) had obesity. Children with obesity had more tonsillectomy/adenoidectomy (p < 0.01) and vascular access (p = 0.04) procedures compared with peers. Additionally, patients with obesity were more likely to have a pre-existing history of liver disease (p < 0.01) and more frequently developed postoperative wound dehiscence (p < 0.01). No other complications occurred more frequently among children with obesity. Conclusions: Children with obesity required more tonsillectomy/adenoidectomy and vascular access procedures. Wound dehiscence was the only complication that was associated with obesity. This suggests that children with obesity are not inherently more prone to experience surgical complications and therefore elective procedures should likely not be deferred until preoperative weight loss is achieved.

Two-Year Experience With Latanoprostene Bunod in Clinical Practice.

PRECIS: We retrospectively reviewed records of patients prescribed latanoprostene bunod 0.024% (LBN) to assess its efficacy and safety in a real-world clinical setting. LBN was efficacious in lowering intraocular pressure (IOP) and had a favorable safety profile. PURPOSE: The aim of this study was to evaluate the usage of LBN, the first topical nitric oxide-donating prostaglandin analog (PGA) for reducing IOP, in clinical practice. PATIENTS AND METHODS: Retrospective review identified patients prescribed LBN by 5 glaucoma specialists at an academic center from January 2018 to November 2019. Fifty-six patients (102 eyes) met inclusion criteria of an IOP measured at the visit LBN was prescribed and at 2 visits ≥7 days after beginning treatment, with no surgeries, lasers or medication changes during follow-up. Main outcome measures were IOP, number of ocular medications, and adverse effects. RESULTS: IOP (mean±SD, mm Hg) at the visit LBN was prescribed was 16.2±4.3 on 3.2±1.5 glaucoma medications. IOP at most recent visit was 13.7±3.8 on 3.2±1.6 medications. Mean IOP reduction was 2.1±3.5 (P<0.0001) at first follow-up, after 38.7±36.5 days, and 2.5±3.3 (P<0.0001) at last follow-up, after 235.9±160.8 days. Pressure decreased ≥2 mm Hg in 60%, ≥3 mm Hg in 46%, and ≥4 mm Hg in 34% of eyes. All patients received LBN as replacement for a PGA or latanoprost/netarsudil fixed-dose combination. Forty-three patients remained on LBN throughout the follow-up period. Seven were discontinued for insufficient pressure control, 4 for adverse effects including pain and itching, and 2 for financial reasons. CONCLUSIONS: In 2 years of clinical use of LBN, patients exhibited IOP reductions that were statistically significant overall and clinically meaningful in 60% of patients. LBN was well-tolerated and may be more efficacious than traditional PGAs.
