Alvarado score: an admission criterion in patients with right iliac fossa pain

Scoring systems in the diagnosis of acute appendicitis in the elderly

“…For scores of 4-6, follow up or imaging with computerized tomography is recommended. [20] Chan et al, [21] in their series of 175 patients with a mean age of 30, reported the negative cut-off point to be 5.…”

The use of the Alvarado score in the management of right lower quadrant abdominal pain in the adult

“…Other studies have shown a PPV of 80%. The incidence of pathology-proven appendicitis increases as the score rises [10,[12][13][14][15]; this is strongly correlated with appendiceal inflammation [2,3,10]. The finding of a normal appendix at surgery for presumed acute appendicitis occurs with a frequency varying from 15 to 30% in the literature [2,10,11].…”

High white blood cell count and erythrocyte sedimentation rate are associated with perforated appendicitis in children

“…In patients presenting with higher Alvarado scores (cut point of 7, the criterion for surgery), pooled diagnostic accuracy results had more limited clinical value (pooled specificity for all studies 0.82, n = 29, [5,8,10,11,[18][19][20][21][22][23][24][25][27][28][29][30][31][32][34][35][36][37][38]41,42,[44][45][46][47]), with pooled specificities ranging from 0.57 for subgroup analysis of men (n = 6, [9,23,30,34,35,45] Figure S1). Overall, heterogeneity was high when all studies were included and was particularly high in the children subgroup as indicated by the variance logit transformed sensitivity and specificity (Table 2) and the prediction ellipses on the SROC curves Additional file 1 - Figure S1).…”
