ALVARADO SCORE FOR APPENDICITIS PDF

BMC Med. The Alvarado score for predicting acute appendicitis: a systematic review. BACKGROUND: The Alvarado score can be used to stratify patients with symptoms of suspected appendicitis; the validity of the score in certain patient groups and at different cut points is still unclear. The aim of this study was to assess the discrimination diagnostic accuracy and calibration performance of the Alvarado score.

BMC Med. The Alvarado score for predicting acute appendicitis: a systematic review. BACKGROUND: The Alvarado score can be used to stratify patients with symptoms of suspected appendicitis; the validity of the score in certain patient groups and at different cut points is still unclear. The aim of this study was to assess the discrimination diagnostic accuracy and calibration performance of the Alvarado score. We assessed the diagnostic accuracy of the score at the two cut-off points: score of 5 1 to 4 vs.

Calibration was analysed across low 1 to 4 , intermediate 5 to 6 and high 7 to 10 risk strata. The analysis focused on three sub-groups: men, women and children. The Alvarado score is well calibrated in men across all risk strata low RR 1. The score over-predicts the probability of appendicitis in children in the intermediate and high risk groups and in women across all risk strata.

The score is well calibrated in men, inconsistent in children and over-predicts the probability of appendicitis in women across all strata of risk.

Alvarado Score for Acute Appendicitis

It was first suggested in and while it is primarily clinical it does take into consideration differential white blood cell count. One recent meta analysis suggests that the Alvarado score may be applicable in the setting of appropriate pretest probability. Ultrasound yielded a sensitivity of In utilizing clinical prediction rules it is critical to understand their applications and limitations. In the case of the Alvarado score, high scores in adult male populations are well validated. Several studies have noted that using the Alvarado score in coordination with clinical assessment, as opposed to using the score for definitive diagnosis, may have some utility.
