What are patients asking and reading online? An analysis of online patient searches about treatments for developmental dysplasia of the hip

Purpose: We aimed to analyze frequently searched questions through Google's "People Also Ask" feature related to four common treatments for developmental dysplasia of the hip (DDH): the Pavlik harness, rhino brace, closed reduction surgery and open reduction surgery.

Methods: Search terms for each treatment were entered into Google Web Search using a clean-install Google Chrome browser. The top frequently asked questions and associated websites were extracted. Questions were categorized using the Rothwell classification model. Websites were evaluated using the JAMA Benchmark Criteria. Chi-square tests were performed.

Results: The initial search yielded 828 questions. Of 479 included questions, the most popular topics were specific activities that patients with DDH can/cannot do (32.8%), technical details about treatments (30.9%) and indications for treatments (18.2%). Websites were commonly academic (59.3%), commercial (40.5%) and governmental (12.3%). There were statistically significant more specific activity questions about Pavlik harnesses than about rhino braces (χ ² = 7.1, p = 0.008), closed reduction (χ ² = 56.5, p < 0.001) and open reduction (χ ² = 14.7, p < 0.001). There were statistically significant more technical details questions about Pavlik harnesses than about closed reduction (χ ² = 4.1, p = 0.04).

Conclusions: This study provides insights into common concerns that parents have about their children's DDH treatment, enabling orthopaedic surgeons to provide more effective and targeted consultations. This is particularly important for DDH because affected patients are often diagnosed within the first few months of life, leaving parents overwhelmed by caring for a newborn child and simultaneously coping with this diagnosis.
