pearls

  • This provides a structured method of evaluation but does not fully account for clinician skill in colposcopy.
  • Visual inspection can be useful, however clinical suspicion along with relevant patient history should be factored into the evaluation. 
  • Does not account for other potentially high risk factors, such as HPV status.

usecase

  • Should be used during colposcopy when assessing cervical lesions.
  • Characteristics of the lesion can assist in prediction of abnormal histology. 
  • These characteristics include color of the lesion, vessel pattern, margins, and appearance on iodine staining.

reasons

Provides a standardized method of assessment and can help differentiate between low- and high-grade lesions.

next_management

  • Cervical lesions found to have an intermediate or high Reid’s Index should be biopsied for additional histopathology evaluation.
  • Lesions that have a low Reid's Index may not require further evaluation. However, the patient’s history and personal risk factors, along with your clinical judgment, should be used to determine if biopsy is necessary at the time of colposcopic examination.
