RESULTS:
Total 141 patients included in the study . Age range in this study was from 15 to 50 years with mean age of 30.191± 6.09 years and mean RIPASA score was 5.375±1.77. Majority of patients were males 83(58.9%). Percentages/frequency of patients according to education status in the study showed uneducated 3(2.1%), primary education 50(35.5%), secondary education 62(44%) and those with higher educational degrees were 26(18.4%) and among socioeconomic status poor were 5(3.5%) , middle class 115(81.6%) and rich were 21(14.9%). Overall RIPASA score diagnosed 28(19.9%) and histopathology diagnosed 27(19.1%) patients with acute appendicitis, with a chi square score of 89.55 and p value of 0.00 and sensitivity of 85.2%, specificity 95.6%, diagnostic accuracy 94%, PPV 82.1% and NPV was 96.4%. Stratification with respect to age range (15-30 years) of RIPASA score versus histopathology (n=87) showed a p value: 0.53 , Sensitivity: 13.8%, Specificity: 82.7%, DA= 48.3%, PPV= 44.4%, NPV= 48.9%. Stratification with respect to age range(31-50 years) of RIPASA score versus histopathology (n=54) showed p value: 0.38, Sensitivity: 29.6%, Specificity: 77.7%, DA= 53.7%, PPV= 57.1%, NPV= 52.5%. Stratification with respect to education status (uneducated) of RIPASA score versus histopathology (n=3) showed p value 1.00, Sensitivity: 33.3%, Specificity: 66.6%, DA= 50%, PPV= 50%, NPV= 50%. Stratification with respect to education (primary) of RIPASA score versus histopathology (n=50) , p value: 0.79, Sensitivity: 20%,Specificity: 82%, DA= 51%, PPV= 52.6%, NPV= 50.6%. Stratification with respect to education (secondary) of RIPASA score versus histopathology (n=62) , p=0.82, Sensitivity: 20.9%, Specificity: 80.6%, DA= 50.8%, PPV= 52%, NPV= 50.5%. Stratification with respect to education (higher) of RIPASA score versus histopathology (n=26), p= 0.714, Sensitivity: 15.3%, Specificity: 80.7%, DA= 48.1%, PPV= 44.4%, NPV= 48.8%. Stratification with respect to socioeconomic status (poor) of RIPASA score versus histopathology (n=5) m p = 1.00, Sensitivity: 20%, Specificity: 80%, DA= 50%, PPV= 50%, NPV= 50%. Stratification with respect to Socioeconomic status (middle) of RIPASA score versus histopathology (n=115) with p value = 0.737, Sensitivity: 20%, Specificity: 81.7%, DA= 50.9%, PPV= 52.2%, NPV= 50.5%. Stratification with respect to Socioeconomic status (rich) of RIPASA score versus histopathology (n=21), p value = 0.707, Sensitivity: 19%, Specificity: 76.1%, DA= 47.6%, PPV= 44.4%, NPV= 48.4%. Stratification with respect to gender (male) of RIPASA score versus histopathology (n=83), p value: 0.58, Sensitivity: 21.6%, Specificity: 74.6%, DA= 48.2%, PPV= 46.1%, NPV: 48.8%. Stratification with respect to gender (female) of RIPASA score versus histopathology (n=58) showed p value: 0.281, Sensitivity: 17.2%, Specificity: 89.6%, DA= 53.4%, PPV= 62.5%, NPV= 52%.
