3.2. The Length of Stay at the GICU

Referring to Table 1, the total hospital stay for the 4347 admissions was 28,432 days. The mean of length of
stay was 6.54 days (SD 7.061) with a median of 4 days; men required slightly longer ICU stays (0.33 day) but
this difference was not statistically significant (p = 0.129). Of all the cases, the longest length of stay of 85 days
was observed in the case of a 70 years woman. It was found that young children (below 12 years) required
longer ICU days (mean 16.33 days for 12 years old patients). For patients above this age, the number of days
at the ICU declined. The ICU stay gradually increased again above the age of 39 years. Results showed that
there is a significant difference (p < 0.001) in average LOS at different primary team who handled each case
with the highest at SARI/PUI ICU (10.07 days), followed by Oncology Team (9.71 days). ICU admission for
obstetric reasons (O&G) had significantly shorter ICU length of stay (4.03 days) compared with the others.

Multiple regression analysis was performed by excluding the outliers in LOS and log linear transformation
of LOS. Race, age and sex had no significant contributions in determining the length of ICU stay and were
