Medical Scores – C
CHILD-PUGH CLASSIFICATION OF SEVERITY OF LIVER DISEASE:
Parameter | Points assigned | ||
1 | 2 | 3 | |
Ascites | Absent | Slight | Moderate |
Bilirrubin, mg/dL | </= 2 | 2-3 | >3 |
Albumin, g/dL | >3.5 | 2.8-3.5 | <2.8 |
Prothrombin time
* Seconds over control * INR |
1-3 <1.8 |
4-6 1.8-2.3 |
>6 >2.3 |
Encephalopathy | None | Grade 1-2 | Grade 3-4 |
- A total score of 5-6 is considered grade A (well-compensated disease); 7-9 is grade B (significant functional compromise); and 10-15 is grade C (decompensated disease).
- These grades correlate with one- and two-year patient survival.
Grade | Points | One-year patient survival (%) | Two-year patient survival (%) |
A: well compensated disease | 5-6 | 100 | 85 |
B: significant functional compromise | 7-9 | 80 | 60 |
C: decompensated disease | 10-15 | 45 | 35 |
SEVERITY SCORE FOR COMMUNITY-ACQUIRED PNEUMONIA (CAP):
Clinical factor | Points |
Confusion | 1 |
Blood urea nitrogen > 19 mg per dL | 1 |
Respiratory rate > 30 breaths per minute | 1 |
Systolic blood pressure < 90 mm Hg or
Diastolic blood pressure < 60 mm Hg |
1 |
Age > 65 years | 1 |
CURB-65 score | Mortality (%) | Recommendation |
0 | 0.6 | Low risk; consider OPD treatment |
1 | 2.7 | |
2 | 6.8 | Short inpatient hospitalization or closely supervised outpatient treatment |
3 | 14.0 | Severe pneumonia; hospitalize and consider admitting to intensive care |
4 or 5 | 27.8 |
CURB-65 = Confusion, Urea nitrogen, Respiratory rate, Blood pressure, 65 years of age and older.

CANADIAN CT HEAD RULE:
- CT Head is only required for patients with minor HI with any one of the following High Risk (for neurological intervention).
-
- GCS score <15 at 2 h after injury
- Suspected open or depressed skull fracture
- Any sign of basal skull fracture (hemotympanum, “raccoon” eyes, CSF otorrhea/rhinorrhoea, Battle’s sign)
- Vomiting ≥2 episodes
- Age ≥65 yr
- Medium Risk (for brain injury on CT)
-
- Amnesia before impact >30 min (i.e., cannot recall events just before impact)
- Dangerous mechanism (pedestrian struck by MVC, occupant ejected from motor vehicle, fall from height >3 ft or five stairs)
- Minor HI is defined as witnessed loss of consciousness, definite amnesia, or witnessed disorientation in a patient with a GCS score of 13-15.
- NB: Canadian CT Head Rule does not apply for non-trauma cases, for GCS<13, age <16, for
patients on Coumadin® and/or having a bleeding disorder, or having an obvious open skull fracture.
THE CANADIAN C-SPINE RULE:
For Alert (GCS Score = 15) and Stable Trauma Patients where C-Spine Injury is a Concern
CIWA WITHDRAWAL SYMPTOMS:
- N/V
- Tremor
- Paroxysmal sweats
- Anxiety
- Agitation
- Visual disturbances
- Tactile disturbances
- Auditory disturbances
- Headache
- Disorientation
10 symptoms each scored out of 7 except orientation, which is scored out of 4.
CVD RISK ASSESSMENT:
- Framingham Risk Score (FRS): 10 yr risk of major CVD event. Calculated based on gender, age, total cholesterol, HDL, sBP, and smoking (>20%: high risk; 10-19%: moderate risk; <10% low risk)
- Reynolds Risk Score: 10 yr risk of major CVD event. Calculated based on age, SBP, total cholesterol, HDL, high sensitivity CRP, family history of MI
Classification | 1 | 2 | 3 |
Serum bilirubin (µmol/L) | <34 | 34-51 | >51 |
Serum albumin (g/L) | >35 | 28-35 | <28 |
INR | <1.7 | 1.7-2.3 | >2.3 |
Presence of ascites | Absent | Controllable | Refractory |
Encephalopathy | Absent | Minimal | Severe |
Interpretation | |||
Points | Class | Life Expectancy | Perioperative Mortality |
5-6 | A | 15-50 yr | 10% |
7-9 | B | Candidate for transplant | 30% |
10-15 | C | 1-3 mo | 82% |
Score: 5-6 (Child’s A), 7-9 (Child’s B), 10-15 (Child’s C)
*Note: Child’s classification is rarely used for shunting (TIPS or other surgical shunts), but is still useful to quantitate the severity of cirrhosis
CHILD-TURCOTTE-PUGH SCORE (PROGNOSIS OF CHRONIC LIVER DISEASE/CIRRHOSIS, INCLUDING POST-OPERATIVELY):

Ascites | Absent | Easily controlled | Poorly controlled |
Bilirubin (µmol/L) | <34 | 34-51 | >51 |
(mg/dL) | <2.0 | 2.0-3.0 | >3.0 |
Coagulation (INR) | <1.7 | 1.7-2.3 | >2.3 |

CURB 65 SCORE – PNEUMONIA CLINICAL PREDICTION TOOL:
Component* | Measurement(s) | Points | Total Score | Mortality | Disposition |
Confusion | Altered mental status | 1 | 0-1 | <5% | Can treat as outpatient |
Urea/BUN | Urea >7 mmol/L or BUN >20 mg/dL | 1 | 2-3 | 5-15% | Consider hospitalization |
Respiratory Rate | >30 breaths/min | 1 | 4-5 | 15-30% | Consider ICU |
Blood Pressure | Systolic <90 or diastolic <60 mmHg | 1 | |||
Age | 65 or older | 1 |
* A CRB-65 score may be applied in the community as its criteria depend on clinical assessment alone
