Undergoing surgery can be a significant event, and while many focus on the physical recovery, an often-overlooked aspect is the potential for postoperative cognitive dysfunction (POCD). The ARISCAT (Assessment of Risk in Older People for Postoperative Cognitive Dysfunction) score is a valuable tool designed to help assess a patient's risk of developing POCD after surgery. Use our calculator below to get an estimate of your ARISCAT score based on key preoperative factors.
Understanding the ARISCAT Score
The ARISCAT score is a validated clinical tool used to predict the risk of postoperative cognitive dysfunction (POCD) in older adults. POCD is a decline in cognitive function (such as memory, attention, and executive function) that can occur after surgery and anesthesia. It can range from mild and transient to severe and persistent, impacting a patient's quality of life and independence.
By assessing several key preoperative factors, the ARISCAT score helps healthcare professionals identify patients who may be at a higher risk. This early identification allows for tailored preoperative planning, anesthetic management, and postoperative care strategies aimed at mitigating these risks and improving patient outcomes.
The Importance of Preoperative Risk Assessment
Assessing the risk of POCD before surgery is crucial. It enables clinicians to:
- Inform patients and their families about potential cognitive risks.
- Optimize patient health before surgery (e.g., managing comorbidities).
- Choose appropriate anesthetic techniques.
- Implement enhanced postoperative monitoring and support.
- Potentially refer patients for cognitive pre-habilitation or specialized follow-up.
How to Use This ARISCAT Calculator
Our ARISCAT calculator is designed to be straightforward. Simply answer the five questions above by selecting the option that best describes the patient's condition or planned surgical procedure. Once all selections are made, click the "Calculate ARISCAT Score" button to receive an estimated score and corresponding risk level.
Factors Included in Our Calculator
This calculator uses a simplified, yet clinically relevant, set of factors from the ARISCAT criteria:
- Age ≥ 75 years: Older age is a significant risk factor for POCD.
- Preoperative cognitive impairment: Existing cognitive issues greatly increase the risk.
- Type of Surgery: More invasive or complex surgeries (e.g., cardiac, neurosurgery) carry a higher risk.
- Emergency Surgery: Emergency procedures often involve greater physiological stress and less preparation, increasing risk.
- General Anesthesia: While all anesthesia carries some risk, general anesthesia is often associated with a higher likelihood of POCD compared to regional techniques.
Interpreting Your ARISCAT Score
The total ARISCAT score ranges from 0 to 6. Each point indicates an increased risk of developing postoperative cognitive dysfunction.
Risk Categories:
- Low Risk (0-2 points): Patients in this category have a relatively low probability of developing POCD. While no surgery is without risk, the likelihood of significant cognitive decline is reduced.
- Intermediate Risk (3-4 points): Patients here have a moderate risk of POCD. Healthcare providers may consider closer monitoring and specific strategies to minimize cognitive impact.
- High Risk (5-6 points): This category indicates a significantly elevated risk of POCD. A thorough discussion with the medical team about potential risks, benefits, and alternative strategies is highly recommended. Comprehensive preoperative and postoperative care plans are essential.

Next Steps and Mitigating Risks
If your ARISCAT score indicates an intermediate or high risk, it is vital to discuss this with your surgeon, anesthesiologist, and primary care physician. They can provide personalized advice and implement strategies to reduce your risk, which may include:
- Optimizing existing medical conditions (e.g., blood pressure, diabetes).
- Considering regional anesthesia options where appropriate.
- Minimizing sedative medications.
- Implementing cognitive pre-habilitation exercises.
- Ensuring rigorous postoperative monitoring for delirium and other complications.
- Early mobilization and adequate pain management after surgery.
