Large-scale media coverage of health care outcomes can have a profound influence on health care utilization by the general population. Google trends (GT), an online resource, allows for tracking of global search volumes as a proxy for determining public interest.
To utilize GT to characterize measurable effects on public interest in breast implant removal procedures and breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) following March 2019 FDA Advisory Committee Meeting and July 2019 public statements by the FDA and Allergan announcing the voluntary recall of BIOCELL textured breast implants.
GT databases of search volumes were collected for terms related to 3 categories including Allergan BIOCELL textured breast implants, BIA-ALCL, and breast implant removal from January 2004 to October 2019. The short-term and long-term interests were determined by the percent change in monthly search volumes with respect to the announcements from Allergan and FDA Advisory Committee Meeting.
Following Allergan's recall announcement, public interest in "textured breast implants" and "allergan breast implant" peaked in July 2019 and rose 456% and 669%, respectively. Public interest in "anaplastic large cell lymphoma breast implant" and "ALCL cancer" rose 200 and 175%, respectively. Long-term interest in all implant removal terms was found to be higher after March 2019 FDA Advisory Committee Meeting than beforehand (p < 0.05).
GT data correlate with shifts in real-world health care utilization and public interest caused by high-profile media coverage, making it a useful tool for providers for real-time prediction of trends in public health in response to observable influences.

大规模的医疗保健结果媒体报道会对大众的医疗保健利用产生深远影响。谷歌趋势（GT）是一种在线资源，可用于跟踪全球搜索量，作为衡量公众兴趣的指标。
利用 GT 描述 2019 年 3 月 FDA 顾问委员会会议后和 2019 年 7 月 FDA 和 Allergan 发布公告自愿召回 BIOCELL 纹理乳房植入物后，公众对乳房植入物去除程序和乳房植入物相关间变性大细胞淋巴瘤（BIA-ALCL）的兴趣的可衡量变化。
从 2004 年 1 月至 2019 年 10 月，从 GT 数据库中收集了与 3 个类别相关的术语的搜索量，包括 Allergan BIOCELL 纹理乳房植入物、BIA-ALCL 和乳房植入物去除。通过每月搜索量与 Allergan 和 FDA 顾问委员会会议公告的百分比变化来确定短期和长期兴趣。
在 Allergan 发布召回公告后，2019 年 7 月公众对“纹理乳房植入物”和“Allergan 乳房植入物”的兴趣达到顶峰，分别上升了 456%和 669%。公众对“间变性大细胞淋巴瘤乳房植入物”和“ALCL 癌症”的兴趣分别上升了 200%和 175%。在 2019 年 3 月 FDA 顾问委员会会议后，与之前相比，所有植入物去除术语的长期兴趣都更高（p < 0.05）。
GT 数据与高知名度媒体报道引起的实际医疗保健利用和公众兴趣的变化相关，使其成为提供者实时预测公众健康趋势的有用工具，以应对可观察到的影响。
