BACKGROUND The present study was undertaken to test the reliability of admission test to identify compromised foetuses and to correlate the test results with different parameters of adverse foetal outcome and mode of delivery. MATERIALS AND METHODS An admission Foetal Heart Rate (FHR) tracings was obtained by cardiotocogram on 100 antenatal mothers, both high and low risk in early labour for 20 minutes and then categorised based on RCOG criteria for interpretation of admission test. Perinatal outcome and mode of delivery were analysed with the help of Kruskal-Wallis chi square test. RESULTS 1. Preeclampsia was the most common high risk factor in our study. 2. Mean gestational age at delivery in high risk group was 37 weeks compared to 39 weeks in low risk group. 3. The percentage of LSCS is more in non-reactive tracings, but this value is not statistically significant as p value is 0.0524 in high risk group and 0.0636 in low risk group. 4. In high risk category in non-reactive group, 6 out of 9 i.e. 66.7% had low Apgar score making the p value 0.0001, which is statistically significant. 5. The duration of hospital stay was also more in babies with non-reactive tracings, a mean of 7 days as compared to 5 days in reactive group in high risk patients. This value is statistically significant as the p value is 0.04. 6. The specificity of admission test in predicting perinatal mortality in high risk pregnancies is quite high; it is 95% and the negative predictive value is 93%. The sensitivity of the test is 70% and positive predictive value is found to be 78%. CONCLUSION By analysing our study carefully and comparing it with similar studies in literature we can conclude any non-reactive tracings should be extended for 40 minutes along with foetal stimulation to reduce the false positive rates. Admission test increases the rate of LSCS in both high and low risk groups. Non-reactive traces in both high and low risk groups are associated with more foetal distress, low Apgar, prolonged NICU care and increased perinatal mortality.

The utility of antepartum fetal heart rate (APFHR) monitoring (nonstress test and the contraction stress test) was evaluated for a 10-year interval from 1974 through 1983. The number of high-risk patients evaluated increased from 2.9 to 25.1% of all deliveries. The decade's perinatal mortality rate differed from 22.4 per 1000 in the nontested population to 11.8 per 1000 in the tested population; the stillbirth rate differed from 11.1 per 1000 to 5.4 per 1000 uncorrected, 2.2 per 1000 corrected, and perinatal morbidity also differed from 26.1 per 1000 to 24.9 per 1000 (NS). Improvement statistics appear to plateau by the fourth year. An abnormal APFHR test was associated with a lethal congenital anomaly in 2.54% of patients (versus 0.5 to 1.5% in the general population). Evaluation for the presence of congenital anomalies appears to be indicated in the fetus with an abnormal APFHR test. A lower stillbirth rate occurred within 4 days of a normal APFHR test (0.027%) compared with a test interval of 5 to 7 days (0.11%). Thus, APFHR testing performed twice weekly may offer a better outcome for the fetus at risk than once weekly testing. This report confirms that the chief value of APFHR testing is its ability to identify the normal healthy fetus. These tests are somewhat less accurate at identification of the sick fetus. The nonstress test and contraction stress test were found to be of similar clinical predictive value.
