The file “Assignment_Trees_Random_Forest_Data.csv” contains the data for 1400 randomly selected patients in the intensive care unit (ICU). Each row in the file corresponds to the record for a patient. The data includes demographic information of the patients and the worst reading of some clinical variables during the patient’s first 24-hour stay in the ICU, and nursing assessment of the patients. It is a common practice to use the worst reading in the first 24 hours of patient ICU stay to predict a patient’s in-hospital mortality (recorded as “Mortality” in the data file). The intuition is that the worst reading captures the initial condition of the patient, which may suggest the probability that the patient will survive after hospital care. Nursing assessments that span the body’s physiological systems have high responsivity to a wide range of modes of patient deterioration. The functional deteriorations they reflect may precede vital sign changes and correlate strongly with in-hospital mortality. The list of all the variables and some brief descriptions are provided below. You are encouraged to search online to find out more information related to each clinical variable.

Age: Patient’s age at the ICU admission

Gender: Patient’s gender

Race: Seven categories of race; disguised as “R1” to “R7”

Mortality: Indicator variable, = 1 if the patient died in the hospital, = 0 otherwise

Temperature: Body temperature (unit: Celsius); a vital sign

RespirarionRate: Frequency of breath (unit: times/min); a vital sign

HeartRate: Heart rate (unit: beats/min); a vital sign

SystolicBP: Systolic blood pressure; maximum pressure in blood vessels during a heartbeat (unit: mmHg); a vital sign

DiastolicBP: Diastolic blood pressure; minimum pressure in blood vessels between two heartbeats (unit: mmHg); a vital sign

SpO2: Peripheral capillary oxygen saturation; the amount of oxygen carried by the red blood cells in the body’s arteries; a vital sign

Haemoglobin: Iron-containing oxygen-transport metalloprotein in the red blood cells (unit: g/dl)

NumWBC: Amount of white blood cell in the blood (unit: number )

ArterialpO2: Partial pressure of oxygen in arterial blood (unit: mmHg)

Creatinine: Byproduct of muscle metabolism that is excreted unchanged by the kidneys, an important indicator of renal health (unit: )

Urea: Amount of urea nitrogen in blood (unit: mmol/L)

GCS: Glasgow Coma Scale/Score; a neurological scale that records the conscious state of a person for initial as well as subsequent assessment (unit: point score from 3 (worst) to 15 (best))

naCardiac: Indicator variable, = 0 if the corresponding criteria in Table 1 are met, = 1 otherwise

naFoodNutrition: Indicator variable, = 0 if the corresponding criteria in Table 1 are met, = 1 otherwise

naGastrointestinal: Indicator variable, = 0 if the corresponding criteria in Table 1 are met, = 1 otherwise

naGenitourinary: Indicator variable, = 0 if the corresponding criteria in Table 1 are met, = 1 otherwise

anMusculoskeletal: Indicator variable, = 0 if the corresponding criteria in Table 1 are met, = 1 otherwise

naNeurological: Indicator variable, = 0 if the corresponding criteria in Table 1 are met, = 1 otherwise

naPain: Indicator variable, = 0 if the corresponding criteria in Table 1 are met, = 1 otherwise

naPeripheralVascular: Indicator variable, = 0 if the corresponding criteria in Table 1 are met, = 1 otherwise

naRespiratory: Indicator variable, = 0 if the corresponding criteria in Table 1 are met, = 1 otherwise

naSkin: Indicator variable, = 0 if the corresponding criteria in Table 1 are met, = 1 otherwise

Table 1: Nursing Assessment Criteria

Nursing AssessmentCriteria

Cardiac Pulse regular, rate 60–100 BPM, skin warm and dry. Blood pressure less than 140/90 and no symptoms of hypotension

Food/Nutrition No difficulty with chewing, swallowing or manual dexterity. Patient consuming > 50% of daily diet ordered as observed

GastrointestinalThe abdomen is soft and non-tender. Bowel sounds present. No nausea or vomiting. Continent. Bowel pattern normal as observed

GenitourinaryVoids without difficulty. Continent. Urine clear, yellow to amber as observed or stated. Urinary catheter patent if present

Musculoskeletal Independently able to move all extremities and perform functional activities as observed or stated (includes assistive devices)

NeurologicalAlert, oriented to person, place, time, and situation. Speech is coherent

Pain Without pain or VAS (visual analog pain scale) < 4 or experiencing chronic pain that is managed effectively

Peripheral/Vascular The extremities are normal or pink and warm. Peripheral pulses palpable. Capillary refill < 3 s. No edema, numbness or tingling

RespiratoryResp. 12–24/min at rest, quiet and regular. Bilateral breath sounds clear. Nail beds and mucous membranes pink. Sputum clear, if present

SkinSkin clean, dry, and intact with no reddened areas. The patient is alert, cooperative and able to reposition himself independently. Braden scale > 15
