Association of Length of Stay at Emergency Services in the Outcome of Admitted Patients
Abstract Background: Access block and overcrowding leading to prolonged stay in emergency room is a common problem of Emergency services of Tribhuvan University Teaching Hospital (TUTH) Kathmandu. Those patients who stayed longer in emergency department might affect continuing care and the ultimate outcome of patients. Study aims to evaluate the association of emergency services length of stay and outcome of admitted patients in wards or Intensive Care Unit at the predefined cut-off value of 6 hour. Methods: It was a prospective cross sectional comparative study done in TUTH, Kathmandu. Data were collected from records from emergency services, wards, ICU and hospital record section from October, 2018 to April, 2019. Adult patients were grouped in to two groups; Emergency services to wards (ES to Wards) and Emergency services to ICU (ES to ICU). Outcome was compared between those admitted within 6hr and those admitted after 6hr of stay in emergency services. Results: A total of 2,059 patients were enrolled over 6 months. Out of them, Male were 55.5% and 42.6% patients were at the age of equal to or above 60 years. Total admitted patients who stayed equal to or less than 6 hr in emergency services was 26.7%. It was found that there was no significant association between Emergency services length of stay (ESLOS) and outcome of admitted total patients (p= 0.160) as well as in ICU (p= 0.559) or Ward admitted patients (p= 0.361). Age was found independent predictor for outcome (p= <0.01). Association of ESLOS and age was also found statistically significant (p= 0.02). Conclusions: Emergency service length of stay is not predictor for outcome of admitted patients. Key words: Emergency services, intensive care unit, length of stay, mortality.
