Integration of physical abuse clinical decision support at 2 general emergency departments.

OBJECTIVE: The study sought to develop and evaluate an electronic health record-based child abuse clinical decision support system in 2 general emergency departments. MATERIALS AND METHODS: A combination of a child abuse screen, natural language processing, physician orders, and discharge diagnoses were used to identify children <2 years of age with injuries suspicious for physical abuse. Providers received an alert and were referred to a physical abuse order set whenever a child triggered the system. Physician compliance with clinical guidelines was compared before and during the intervention. RESULTS: A total of 242 children triggered the system, 86 during the preintervention and 156 during the intervention. The number of children identified with suspicious injuries increased 4-fold during the intervention (P < .001). Compliance was 70% (7 of 10) in the preintervention period vs 50% (22 of 44) in the intervention, a change that was not statistically different (P = .55). Fifty-two percent of providers said that receiving the alert changed their clinical decision making. There was no relationship between compliance and provider or patient demographics. CONCLUSIONS: A multifaceted child abuse clinical decision support system resulted in a marked increase in the number of young children identified as having injuries suspicious for physical abuse in 2 general emergency departments. Compliance with published guidelines did not change; we hypothesize that this is related to the increased number of children identified with suspicious, but less serious injuries. These injuries were likely missed preintervention. Tracking compliance with guidelines over time will be important to assess whether compliance increases as physician comfort with evaluation of suspected physical abuse in young children improves.

Implementation of routine electronic health record-based child abuse screening in General Emergency Departments.

BACKGROUND: Routine child abuse screening is an approach to early identification of abuse. Previous studies evaluated paper-based screens; the widespread use of electronic health records suggests that screening is more likely to succeed if integrated into the electronic record. OBJECTIVE: To implement an electronic health record-based child abuse screen in a diverse hospital system and to evaluate the screening rate, rate of positive screens, and number of reports to Child Protective Services and assess whether hospital and patient characteristics are associated with these rates. PARTICIPANTS AND SETTING: Children <13 years of age evaluated at one of 13 Emergency Departments within University of Pittsburgh Medical Center Health System. METHODS: A previously validated child abuse screen was slightly modified and integrated into Cerner. Multivariable logistic regression models were used to estimate the odds of the outcomes of interest, controlling for key covariates. RESULTS: Of 17,163 eligible children: 68% received the screen of which 1.9% were positive. The rate of reports to Child Protective Services was higher among children who were screened (p < 0.0001). Younger children were more likely to be screened, have a positive screen, and have a report filed. There was no difference in the odds of being screened according to hospital teaching status, size or urban vs rural location. CONCLUSIONS: A child abuse screening tool can be integrated into the electronic health record in a large health-care network. The increased number of reports among children who were screened suggests that screening facilitates detection of suspected maltreatment.

Effects of Lighting on Reading Speed as a Function of Letter Size.

OBJECTIVE: We sought to determine under what conditions brighter lighting improves reading performance. METHOD: Thirteen participants with typical sight and 9 participants with age-related macular degeneration (AMD) read sentences ranging from 0.0 to 1.3 logMAR under luminance levels ranging from 3.5 to 696 cd/m². RESULTS: At the dimmest luminance level (3.5 cd/m²), reading speeds were slowest at the smaller letter sizes and reached an asymptote for larger sizes. When luminance was increased to 30 cd/m², reading speed increased only for the smaller letter sizes. Additional lighting did not increase reading speeds for any letter size. Similar size-related effects of luminance were observed in participants with AMD. CONCLUSION: In some instances, performance on acuity-limited tasks might be improved by brighter lighting. However, brighter lighting does not always improve reading; the magnitude of the effect depends on the text size and the relative changes in light level.

Costs and utilization of end-stage glaucoma patients receiving visual rehabilitation care: a US multisite retrospective study.

PURPOSE: Glaucoma is a prevalent ophthalmologic disease and leading cause of blindness. A retrospective analysis was conducted to evaluate resources and costs for end-stage glaucoma patients receiving visual rehabilitation care (VRC). MATERIALS AND METHODS: A chart review was conducted in 3 United States VRC centers. Charts of patients with primary open-angle glaucoma as the primary cause of vision loss (1998 to 2003) were selected, yielding 81 records. Data were collected from patient-level billing and reimbursement records (ophthalmologist/optometrist visits, glaucoma medications, procedures, and specialized low-vision and glaucoma-related services). Visual rehabilitation services included utilization of low-vision devices, assessment of daily functioning, orientation and mobility training, and patient counseling. RESULTS: Mean age at baseline was 72.7 years [standard deviation (SD)=17.2, range: 29 to 95]. Of those with known sex (n=77), 55.8% were women. Medicare was the payer type for most patients (59.3%), whereas 20% had Medicaid. Mean number of visits was 7.1 (SD=6.1) in year 1 and 3.7 (SD=4.2) in year 2, for an annual mean of 5.4 (SD=5.0) visits overall. Total mean cost per patient in year 1 was greater than year 2 [$2170 (SD=$2252) vs. $1202 (SD=$1080), respectively]; of the total 2-year costs, 15% were VRC, 37% ophthalmology care, and 48% pharmacy. Analysis of nonpharmacy costs revealed that VRC accounted for 28% and ophthalmology for 72%. CONCLUSIONS: End-stage glaucoma is associated with appreciable resource utilization and costs, because of both vision rehabilitation and ophthalmology care. Advanced primary open-angle glaucoma has a substantial cost-of-illness, warranting improved management in early stages of disease.

Awareness of age-related macular degeneration in adults: the results of a large-scale international survey.

BACKGROUND: Early detection and prompt implementation of appropriate rehabilitation services and therapy can help minimize the long-term disability that results from age-related macular degeneration (ARMD). The level of awareness of ARMD among the general public may influence early detection of this disease. METHODS: Random samples of European and North American populations were interviewed in an international survey designed to assess the attitudes of people to eye examinations, awareness of the causes of vision loss, awareness of ARMD, and knowledge of its treatment options. RESULTS: A total of 7,830 adults of at least 18 years of age were questioned. The main finding was that knowledge of ARMD is poor-the majority of respondents (70%) were not at all familiar with ARMD. Only 2% of participants knew that ARMD is the leading cause of severe vision loss in adults 50 years of age or older, while a majority of those surveyed (75%) was unaware of treatments available for ARMD. CONCLUSIONS: These data show that there is low public awareness of ARMD, which may result in people with ARMD not receiving prompt medical advice and treatment. There is a need for a wide-ranging educational initiative to increase awareness of ARMD and highlight the importance of undergoing regular eye examinations.
