Evaluation of a digital store-and-forward colposcopic system--a pilot study to assess usability for telemedicine.
We evaluated the diagnostic reliability of cervical examination using digital colposcopy compared with conventional binocular colposcopy. A total of 315 patients were examined and diagnosed by a colposcopist on-site. During the colposcopic examination, digital camera images were stored on a PC (median five pictures per patient). A second physician, experienced in colposcopy, re-evaluated the initial diagnostic findings using the stored digital images. The primary and secondary findings in each patient were categorized according to the Rome classification system. There was agreement between the primary and secondary examiners in 69% of cases (kappa=0.60). There was no systematic bias in terms of under- or over-rating. The proportion of non-assessable colposcopic examinations was 9%. Digital colposcopy was reliable and provided advantages in terms of a better follow-up examination and internal quality control of the diagnosis. The pilot study suggests that telecolposcopy may provide better training and further education for physicians and students, and may also improve the diagnostic possibilities in gynaecology.
