Background

Various means to facilit ate accurate biopsy site identification have been proposed.

Objective

To determine the accuracy of biopsy site identification by using photographs taken with a patient's digital device by a dermatologist versus professional medical photography.

Methods

Photographs of circled biopsy sites were taken with personal digital devices by the principal investigator (PI). Another set of photographs was taken by a professional photographer. Secondary photographs were taken of the biopsy site location pointed to by the staff and PI on the basis of the personal digital device image and professional medical photography, respectively. On the basis of secondary photographs, 2 independent dermatologists determined whether the skin biopsy locations pointed out by the staff were consistent with the ones pointed out by PI.

Results

Per dermatologist A, the staff correctly identified all 53 biopsy sites. Per dermatologist B, the staff were correct on 51 of 53 observations. Dermatologist C, the final arbiter, concurred with dermatologist A on the 2 cases in which dermatologist B was not certain of the location of the biopsy site.

Limitations

The mean interval from initial biopsy to reidentification of the site was 36.2 days.

Conclusion

Utilizing patients' personal digital devices is a cost-effective, Health Insurance Portability and Accountability Act–compliant, and readily available means to identify skin biopsy sites.

使用个人数字设备进行手术部位识别：前瞻性初步研究

背景

已经提出了各种有助于精确的活检部位识别的手段。

客观的

为了确定活检部位识别的准确性，方法是使用皮肤科医生与专业医学摄影人员使用患者的数字设备拍摄的照片。

方法

首席调查员（PI）使用个人数字设备拍摄了带圆圈的活检部位的照片。另一组照片是由专业摄影师拍摄的。工作人员和PI分别根据个人数字设备图像和专业医学照片拍摄了活检部位的二次照片。根据第二张照片，两名独立的皮肤科医生确定了工作人员指出的皮肤活检位置是否与PI指出的一致。

结果

根据皮肤科医生A，工作人员正确地识别了全部53个活检部位。根据皮肤科医生B，工作人员对53项观察中的51项是正确的。皮肤科医生C是最终的仲裁人，在皮肤科医生B不能确定活检部位的情况下，与皮肤科医生A达成了一致意见。

局限性

从初次活检到再次发现该部位的平均间隔为36.2天。

结论

利用患者的个人数字设备是符合成本效益的，符合《健康保险可移植性和责任法案》的，并且是一种易于使用的识别皮肤活检部位的方法。
