AI Article Synopsis
- The study aimed to estimate the prevalence and characteristics of low-vision (LV) patients using electronic health record (EHR) data from the Wilmer Eye Institute in 2014.
- Out of over 100,000 patients assessed, 7.7% were found to have prevalent LV, with higher rates observed in urban hospitals and among older adults, particularly those aged 80 and above.
- The findings suggest that EHR data can effectively identify LV prevalence and highlight specific clinical settings, like retina and glaucoma clinics, where higher rates are found.
Article Abstract
Purpose: To use electronic health record (EHR) data to estimate the prevalence and characteristics of low-vision (LV) patients.
Methods: EHR data were obtained for all patients at the nine clinical locations of the Wilmer Eye Institute in 2014. LV status at each visit was defined as visual acuity (VA) worse than 20/40 in the better-seeing eye. Prevalence and incidence estimates were determined over a 12-month period. Demographic and clinical data were used to compare the characteristics of patients with and without LV. Logistic regression analyses were used to determine prevalence and incidence estimates adjusted for age, sex, race, and ethnicity.
Results: A total of 100,755 patients were included in the analysis. There were 7752 (7.7%) prevalent and 1962 (2.1%) incident cases of LV. Among patients with LV, 55% had VA between 20/40 and 20/60. Outside of LV clinics, retina and glaucoma clinics had the highest prevalence (18% and 14%, respectively) and incidence (5% and 4%, respectively) of LV. The urban hospital center had twice the prevalence of LV than suburban clinics (11.5% vs. 5.6%). The odds of prevalent LV was greatest among patients 80 years and older (odds ratio = 6.18; 95% confidence interval: 5.62-6.80) as compared to those 20-39 years old.
Conclusions: EHR can be used to estimate the prevalence and describe the characteristics of patients with LV seeking ophthalmic care. The highest prevalence rates of LV are observed in the urban setting and among patients obtaining retina and glaucoma care.

Background: Assisted partner services (APSs; sometimes called index testing) are now being brought to scale as a high-yield HIV testing strategy in many nations. However, the success of APSs is often hampered by low levels of partner elicitation. The Computer-Assisted Self-Interview (CASI)-Plus study sought to develop and test a mobile health (mHealth) tool to increase the elicitation of sexual and needle-sharing partners among persons with newly diagnosed HIV.

Cardiac arrhythmias are major global health concern and their early detection is critical for diagnosis. This study comprehensively evaluates the effectiveness of CNNs and LSTMs for the classification of cardiac arrhythmias, considering three PhysioNet datasets. ECG records are segmented to accommodate around ∼10s of ECG data.

There is paucity of studies focused on the enablers and barriers to community pharmacists' readiness to deprescribe inappropriate medications for older adults in developing settings. The current study assessed the enablers and barriers to community pharmacists' readiness to implement deprescribing of inappropriate medications for older adults. A cross-sectional survey of 252 community pharmacists was conducted in Qatar with a pre-tested 24-item questionnaire developed with the theory of domain framework.

Background To gain an understanding of chlamydia (CT) and gonorrhoea (NG) testing conducted within an annual health check (AHC) and in standard clinical consultations for clients aged 15-29years attending an urban Aboriginal Community Controlled Health Service in the period 2016-2021. Methods De-identified electronic medical record data were extracted and analysed on CT and NG testing by sex, age, Indigenous status and the context of testing (conducted within an AHC or not). An access, testing, and diagnosis cascade for CT and NG, inclusive of an AHC, was constructed.
