Risk scores Flashcards
Name 3 risk score commonly use preoperative.
Name the 6 subgroups of the ASA score with examples
What is the risk per subgroup of the ASA score
- 0.1%
- 0.7%
- 3.5%
- 18.3%
- 93.3%
What are the disadvantages of the ASA score
it does not take into account any preoperative optimisation of the patient, the planned surgery, or the level of postoperative care.
ASA scoring is subjective, so may lead to significant interoperator variability.
Which Risk score is used to estimate cardiac complications?
RCRI
What are the components of rcri?
Insulin-dependent diabetes
Renal impairment with creatinine >176.9mcmol/l
History of cardiac failure
History of stroke or TIA
History of CAD/MI
What is the risk % based on the score
<1= 0.4%
1= 0.9%
2 =6.6%
>3 = 11%
Advantage of RCRI
TheRCRI is a simple, quick, and non-invasive method for identifying those at increased risk of perioperative cardiac complications.
It can be used to stratify patients who may warrant further investigation, and those who do not.
Disadvantages of RCRI
The data are from a single teaching hospital in patients undergoing non-emergent operations.
○ It is therefore not generalisable to lower-risk populations, such as patients having only minor procedures, or in high-risk populations or those undergoing emergency surgery.
○ Finally, the original data were collected 20 yrs ago and therefore may not reflect current patients presenting for surgery.
Risk score for postoperative pulmonary complications
Assess respiratory risk in surgical patients in Catalonia (ARISCAT) is the most widely used risk score for predicting postoperative pulmonary complications (PPC
What are the variables for ARISCAT
Age
Recent resp infection <1/12
Incision site
Presence of anemia
Duration of surgery
Emergency/elective
How are the patients graded according to the ARISCAT score
Low risk¼<26 points; intermediate risk¼26e44 points; high risk¼>45 points.
What are the composition measures of the ARISCAT score
What are the adverse outcomes measured by ARISCAT SCORE
pneumonia,
acute respiratory distress syndrome (ARDS), and
pulmonary embolus
What are the main advantages of the ARISCAT score
Using the ARISCAT risk score helps identify the patient groups susceptible to PPCs. In an elective setting it can beused to aid surgical timing, as it contains modifiable factors such as anaemiaandrespiratory infectionwithin thepast month
