colic

Colic horse data set


Description

This is a modified version of the original training data set taken from the UCI repository, see reference. The modifications are only related to having appropriate levels for factor variables. This data set is about horse diseases where the task is to determine, if the lesion of the horse was surgical or not.

Format

A training data frame with 300 observations on the following 31 variables.

surgery

yes or no

age

1 equals an adult horse, 2 is a horse younger than 6 months

hospitalID

ID

temp_rectal

rectal temperature

pulse

heart rate in beats per minute

respiratory_rate

a normal rate is between 8 and 10

temp_extreme

temperature of extremities

pulse_peripheral

factor with four categories

capillayr_refill_time

a clinical judgement. The longer the refill, the poorer the circulation. Possible values are 1 = < 3 seconds and 2 = >= 3 seconds

pain

a subjective judgement of the horse's pain level

peristalsis

an indication of the activity in the horse's gut. As the gut becomes more distended or the horse becomes more toxic, the activity decreases

abdominal_distension

An animal with abdominal distension is likely to be painful and have reduced gut motility. A horse with severe abdominal distension is likely to require surgery just tio relieve the pressure

nasogastric_tube

This refers to any gas coming out of the tube. A large gas cap in the stomach is likely to give the horse discomfort

nasogastric_reflux

posible values are 1 = none, 2 = > 1 liter, 3 = < 1 liter. The greater amount of reflux, the more likelihood that there is some serious obstruction to the fluid passage from the rest of the intestine

nasogastric_reflux_PH

scale is from 0 to 14 with 7 being neutral. Normal values are in the 3 to 4 range

rectal_examination

Rectal examination. Absent feces probably indicates an obstruction

abdomen

abdomen. possible values 1 = normal, 2 = other, 3 = firm feces in the large intestine, 4 = distended small intestine, 5 = distended large intestine

cell_volume

packed cell volume. normal range is 30 to 50. The level rises as the circulation becomes compromised or as the animal becomes dehydrated.

protein

total protein. Normal values lie in the 6-7.5 (gms/dL) range. The higher the value the greater the dehydration

abdominocentesis_appearance

Abdominocentesis appearance. A needle is put in the horse's abdomen and fluid is obtained from the abdominal cavity

abdomcentesis_protein

abdomcentesis total protein. The higher the level of protein the more likely it is to have a compromised gut. Values are in gms/dL

outcome

What eventually happened to the horse?

surgical_lesion

retrospectively, was the problem (lesion) surgical?

lesion_type1

type of lesion

lesion_type2

type of lesion

lesion_type3

type of lesion

cp_data
temp_extreme_ordered

temperature of extremities (ordered)

mucous_membranes_col

mucous membranes. A subjective measurement of colour

mucous_membranes_group

different recodings of mucous membrances
