Telehealth Demand Trends During the COVID-19 Pandemic in the Top 50 Most Affected Countries: Infodemiological Evaluation

BackgroundThe COVID-19 pandemic has led to urgent calls for the adoption of telehealth solutions. However, public interest and demand for telehealth during the pandemic remain unknown.ObjectiveWe used an infodemiological approach to estimate the worldwide demand for telehealth services during COVID-19, focusing on the 50 most affected countries and comparing the demand for such services with the level of information and communications technology (ICT) infrastructure available.MethodsWe used Google Trends, the Baidu Index (China), and Yandex Keyword Statistics (Russia) to extract data on worldwide and individual countries’ telehealth-related internet searches from January 1 to July 7, 2020, presented as relative search volumes (RSV; range 0-100). Daily COVID-19 cases and deaths were retrieved from the World Health Organization. Individual countries’ ICT infrastructure profiles were retrieved from the World Economic Forum Report.ResultsAcross the 50 countries, the mean RSV was 18.5 (SD 23.2), and the mean ICT index was 62.1 (SD 15.0). An overall spike in worldwide telehealth-related RSVs was observed from March 11, 2020 (RSV peaked to 76.0), which then tailed off in June-July 2020 (mean RSV for the period was 25.8), but remained higher than pre-March RSVs (mean 7.29). By country, 42 (84%) manifested increased RSVs over the evaluation period, with the highest observed in Canada (RSV=100) and the United States (RSV=96). When evaluating associations between RSV and the ICT index, both the United States and Canada demonstrated high RSVs and ICT scores (≥70.3). In contrast, European countries had relatively lower RSVs (range 3.4-19.5) despite high ICT index scores (mean 70.3). Several Latin American (Brazil, Chile, Colombia) and South Asian (India, Bangladesh, Pakistan) countries demonstrated relatively higher RSVs (range 13.8-73.3) but low ICT index scores (mean 44.6), indicating that the telehealth demand outstrips the current ICT infrastructure.ConclusionsThere is generally increased interest and demand for telehealth services across the 50 countries most affected by COVID-19, highlighting the need to scale up telehealth capabilities, during and beyond the pandemic.     

Visual Morbidity and Ocular Complications in Presumed Intraocular Tuberculosis: An Analysis of 354 Cases from a Non-Endemic Population

Purpose: To describe the visual morbidity associated with intraocular tuberculosis (TB) and to report ocular complications of intraocular TB.

Methods: Retrospective cohort study of patients diagnosed with intraocular TB at a tertiary referral eye care hospital in central London. Data on baseline and final best-corrected visual acuity (BCVA) along with ocular complications were collected and analyzed.

Results: In total, 354 patients with intraocular TB were included in this study. Mean age was 48.45 years (range 19–94) and follow-up was 22.56 ± 7.44 (range 6–30) months post cessation of therapy. Blindness as defined by the World Health Organization was reported in 11 (3.11%) patients at baseline and 13 (3.67%) patients at follow-up. The most common ocular complications were cystoid macular edema (n = 107, 30.5%) and glaucoma (n = 99, 28.12%).

Conclusion: Intraocular TB can be associated with significant ocular morbidity. Early recognition, treatment, and regular follow-up of this complex disease may help to reduce visual morbidity and ocular complications.
