Current breast implant prevalence within the general population remains elusive. An accurate prevalence is critical to serve as the denominator for any assessment of breast implant-related complication. The purpose of this manuscript is to assess this prevalence in women aged 20-70 years in Italy.
Eight reviewers, demonstrating a mean sensitivity of 87.0% and specificity of 97.0%, were recruited for retrospective identification of implants on chest radiographs from a tertiary academic hospital in a major urban setting. Three final reviewers were selected, and they assessed all eligible chest radiographs collected between January and December 2019. The hospital-based population was compared to epidemiological data at a local, regional and national level to demonstrate homogeneity of age structures using the phi correlation coefficient.
We identified 3,448 chest X-rays which yielded 140 implants, with an overall prevalence of 4.1% for women aged 20-70. Implants were bilateral in 76% of cases and unilateral in 24%. They were placed cosmetically in 47.1% cases and used for reconstruction in 52.9% cases. Phi correlation coefficient found no differences across hospital-based, local, regional and national populations.
A validated method was performed to estimate implant prevalence from an academic hospital in a major urban setting at 4.1% and was used to estimate national prevalence in Italy. The implications of this epidemiologic study may reach across national borders for improved understanding of breast implant epidemiology and in predicting the total number of patients within a given population that may be affected by device complications.

目前一般人群中乳房植入物的流行率仍难以确定。准确的流行率对于评估与乳房植入物相关的并发症至关重要。本文旨在评估意大利 20-70 岁女性的这一流行率。
招募了 8 名评估者，他们的平均敏感度为 87.0%，特异性为 97.0%，用于回顾性识别位于主要城市的三级学术医院的胸部 X 光片中的植入物。选择了 3 名最终评估者，他们评估了 2019 年 1 月至 12 月期间收集的所有合格的胸部 X 光片。将基于医院的人群与当地、地区和国家一级的流行病学数据进行比较，使用 phi 相关系数证明年龄结构的同质性。
我们从一家学术医院的 3448 张胸部 X 光片中确定了 140 个植入物，20-70 岁女性的总体流行率为 4.1%。在 76%的病例中，植入物是双侧的，在 24%的病例中是单侧的。在 47.1%的病例中，植入物是美容性的，在 52.9%的病例中是用于重建的。phi 相关系数未发现基于医院、当地、地区和国家人群之间的差异。
采用经过验证的方法从主要城市的一家学术医院估计植入物的流行率为 4.1%，并用于估计意大利的全国流行率。这项流行病学研究的意义可能跨越国界，有助于更好地了解乳房植入物的流行病学，并预测特定人群中可能受到器械并发症影响的患者总数。
