Computation description:	The numerator: include records with the triage categories from 1 to 5. exclude records if the Waiting time to service is invalid. Length of stay < 0. Presentation date or time are missing. Physcial departure date or time is missing. The 90^th percentile (the ninetieth percentage value in a group of data arranged from lowest to highest value for time waited) represents the time within which 90% of patients were admitted and physically left the emergency department. For example, if there were 100 observations admitted to the hospital, the 90^th percentile will correspond to the average time for eh 90^th and 91^st observations. If there were 101 observations, the 90^th percentile will correspond to the time for the 91^st observation. Emergency department stay time is calculated by subtracting the date and time the patient presented to the emergency department from the date and time the patient physically left the emergency department.
