Prevalence of web analytics technology on hospital websites in the United States of America (Preprint)
BACKGROUND Web analytics are used on the majority of all high traffic web sites. These technologies are used to measure and enhance the impact of advertising and to create web visitor profiles of individual internet users. Visitor behavioral data collected by web analytics forms the foundation of the advertising ecosystem that generates revenue for technology companies such as Google and Facebook. The potential impacts of web analytics technology on healthcare are significant. Gaining a better understanding of the prevalence and characteristics of web analytics technology use on hospital websites is an important first step to understand the scope of this challenge. OBJECTIVE Determine the prevalence of web analytics use on hospital websites in the United States. METHODS An observational study on hospital websites in the United States was conducted obtaining website information for all general and critical access hospitals from the Homeland Infrastructure Foundation-Level Data (HIFLD) compiled by the Department of Homeland Security. These websites were then analyzed with the BuiltWith web technology analysis tool (BuiltWith Pty Ltd, Sidney, Australia, www.builtwith.com) to determine what web analytics products were active on hospital websites. Results were exported to a spreadsheet for data analysis. RESULTS Data from 4,829 hospital websites was analyzed. Web analytics technology was found on 78% of all hospital websites, with a range of 0 to 34 analytics products installed on a hospital website. The most common analytics technology installed was Google Universal Analytics, found on 62% of hospital websites. Comparisons between general acute care and critical access hospitals shows a higher prevalence (81% vs. 66%, p < 0.001) and mean number (4.49 vs. 2.56, p < 0.001) of web analytics products on general acute care hospital websites. Google is the dominant provider of web analytics for general acute care and critical access hospitals (75% vs. 61%, p < 0.001). Facebook is a distant second place provider with 31% and 13% respectively (p < 0.001). CONCLUSIONS Web analytics technology, predominately in the form of Google services, is extremely common on the websites of public hospitals in the United States. Further research is required to determine how the use of this technology may impact healthcare and the public. CLINICALTRIAL N/A
