Objective: The predictive value of colposcopy is not as reliable as it was presumed. The Reid colposcopic index is a prevalently used scoring system which was devised to standardize the colposcopic assessment and to predict the histology. The Swede score formulated by Strander et al. in 2005 is a simple scoring system which includes five variables also including the size of the lesion. This study aims to validate the accuracy of the Swede score in the prediction of high-grade lesions (CIN-II or higher). Methods: The evaluation was carried out in the Department of Obstetrics and Gynecology at Sri Ramachandra Medical College between January 2015 and July 2015. Seventy-nine patients who attended the gynecology outpatient department who underwent colposcopy and guided biopsy were included. The participating colposcopists were well trained. Swede score was calculated for each patient after colposcopy and noted. It was then evaluated with the final histopathology after either colposcopic biopsy or excisional cervical biopsy. Since it was not a research study and it was an evaluation, the management of patients was not influenced by the Swede score. Results: Whenever the final diagnosis of cervical lesions was CIN-II or higher, our study showed that the Swede score had 71% sensitivity, 95% specificity, 77% positive predictive value and 94% negative predictive value. Conclusion: The specificity for a score of 8 or more was 95%, therefore higher scores within the system may more accurately predict high-grade lesions. Swede score is a valid simplified scoring system in accurately predicting high-grade lesions.
