What is the Geriatric Oncology G8 Questionnaire?

The Geriatric Oncology G8 Questionnaire is a validated screening tool used to assess the general health and frailty of elderly cancer patients. Since aging can significantly impact how a person tolerates cancer treatments, this questionnaire helps identify patients who may need a more in-depth geriatric assessment before starting therapy. The G8 questionnaire is composed of eight key factors related to nutrition, mobility, cognitive function, and overall well-being.

Developed as a rapid screening tool, the G8 is widely used in oncology to determine whether an older patient is fit for standard cancer treatments or if they require tailored care to reduce risks. By evaluating factors such as weight loss, physical mobility, and polypharmacy (use of multiple medications), the questionnaire provides a score that helps oncologists make informed treatment decisions.

Purpose of the Calculator

The purpose of the G8 Questionnaire Calculator is to simplify the assessment process by allowing healthcare providers, caregivers, and patients to obtain a G8 score quickly and efficiently. Instead of manually scoring the questionnaire, this calculator automates the process, reducing the chance of errors and ensuring a consistent evaluation.

This tool is especially useful in clinical settings where rapid assessment is necessary to determine whether an elderly cancer patient may need additional support before beginning treatment. A low G8 score suggests that the patient might benefit from a more detailed geriatric evaluation, which could lead to adjustments in their treatment plan, such as modified chemotherapy doses or supportive care interventions.

Who Should Use It?

Healthcare Professionals

Oncologists, geriatricians, nurses, and other healthcare providers use the G8 Questionnaire Calculator to assess the frailty of elderly cancer patients. This tool helps them decide whether a patient is fit for standard cancer treatments or if a more personalized approach is required. A low G8 score often indicates that further assessments, such as a Comprehensive Geriatric Assessment (CGA), should be performed to optimize patient care.

Caregivers and Family Members

Family members and caregivers of elderly cancer patients can use the calculator to better understand their loved one's health status. While the G8 score does not replace a professional medical evaluation, it provides insight into potential concerns such as malnutrition, mobility limitations, and cognitive decline. This information can be valuable when discussing treatment options with doctors.

Older Adults Undergoing Cancer Treatment

Senior patients themselves can use the G8 Calculator as an initial self-assessment tool. By answering the questionnaire, they can gain awareness of their overall health status and identify potential risks associated with their cancer treatment. This can empower patients to have more informed discussions with their healthcare team about their treatment plans and supportive care options.

How to Use the G8 Questionnaire Calculator

The G8 Questionnaire Calculator is designed to be a simple and efficient tool for assessing the health status of elderly cancer patients. By answering a set of eight questions, users can quickly determine a patient’s frailty level and whether further geriatric evaluation is necessary. This tool is particularly useful for oncologists, caregivers, and family members who need a rapid screening method.

Step-by-Step Guide

Using the G8 Questionnaire Calculator is straightforward. Follow these steps to complete the assessment:

  1. Access the Calculator: Open the G8 Questionnaire Calculator on your device.
  2. Read Each Question Carefully: The questionnaire consists of eight questions covering appetite, weight loss, mobility, neuropsychiatric conditions, body mass index (BMI), medication use, self-perceived health status, and age.
  3. Select the Most Accurate Answer: For each question, choose the response that best describes the patient’s condition. Each answer has a specific score assigned to it.
  4. Complete All Questions: Ensure that every question is answered to get an accurate score.
  5. Click the "Calculate" Button: After selecting all responses, click the button to compute the final G8 score.
  6. Review the Score: The calculator will display the total score, which helps determine whether further assessment is needed.

Answering the Questions

The G8 Questionnaire consists of eight key health-related questions:

  • Loss of Appetite: Has the patient experienced a reduced appetite in the last three months?
  • Recent Weight Loss: Has the patient lost weight (over 3 kg) in the past three months?
  • Mobility (Motricity): Does the patient move independently, or do they require assistance?
  • Neuropsychiatric Disorders: Does the patient have dementia, depression, or other cognitive issues?
  • Body Mass Index (BMI): What is the patient’s BMI based on their height and weight?
  • Medication Use: Does the patient take more than three medications regularly?
  • Self-Perceived Health: Does the patient feel healthier, the same, or worse compared to others their age?
  • Age: How old is the patient? (Different age ranges contribute differently to the total score.)

Each response contributes a score, and the final total helps indicate whether the patient is at risk.

Interpreting the Results

After answering all the questions, the calculator will provide a total score. The interpretation of the score is as follows:

  • Score ≥ 14: The patient is considered fit, and no further geriatric assessment is typically required.
  • Score < 14: The patient may be at risk and should undergo a Comprehensive Geriatric Assessment (CGA) to evaluate their health in more detail.

A low score suggests that the patient may need additional support in areas such as nutrition, mobility, and medication management. Healthcare providers can use this information to adjust cancer treatments, ensuring that elderly patients receive care that aligns with their overall health condition.

Assessment Criteria

The G8 Questionnaire evaluates the overall health and frailty of elderly cancer patients based on eight key criteria. Each criterion contributes to the final score, which helps determine whether a patient may require further geriatric assessment before undergoing cancer treatment.

Loss of Appetite

Appetite loss is a common issue in elderly patients, particularly those undergoing cancer treatment. The questionnaire assesses whether the patient has experienced a decreased appetite over the last three months due to digestive problems, difficulty chewing or swallowing, or a general loss of interest in food.

  • Severe anorexia (0 points): The patient has significant appetite loss and struggles to eat.
  • Moderate anorexia (1 point): The patient has some appetite reduction but can still eat.
  • No anorexia (2 points): The patient has a normal appetite.

Recent Weight Loss (< 3 months)

Unintentional weight loss is a sign of poor nutritional status, which can impact treatment outcomes. The questionnaire measures how much weight the patient has lost in the past three months.

  • More than 3 kg (0 points): Significant weight loss.
  • Unknown weight loss (1 point): The patient is unsure about recent weight changes.
  • Between 1 and 3 kg (2 points): Moderate weight loss.
  • No weight loss (3 points): The patient has maintained their weight.

Motricity (Mobility Levels)

Mobility is a crucial factor in determining a patient’s functional independence. The G8 questionnaire evaluates how well the patient can move around.

  • From bed to chair (0 points): The patient is mostly bedridden or needs assistance.
  • Autonomous indoors (1 point): The patient can move around independently inside the home.
  • Leaving the home (2 points): The patient can walk outside independently.

Neuropsychiatric Disorders (Dementia or Depression)

Mental health and cognitive function significantly affect a patient’s ability to manage their own care and tolerate cancer treatments.

  • Dementia or severe depression (0 points): The patient has severe cognitive or mood disorders.
  • Dementia or moderate depression (1 point): The patient has noticeable but less severe cognitive or mood issues.
  • No psychiatric disorder (2 points): The patient does not have significant mental health concerns.

Body Mass Index (BMI)

A low BMI may indicate malnutrition or frailty, which can impact a patient’s ability to recover from treatment.

  • BMI < 19 (0 points): Underweight and at higher risk of complications.
  • 19 ≤ BMI < 21 (1 point): Slightly underweight.
  • 21 ≤ BMI < 23 (2 points): Borderline healthy weight.
  • BMI ≥ 23 (3 points): Normal or higher BMI.

Medication Use (More than 3 Medications)

Taking multiple medications (polypharmacy) increases the risk of drug interactions and side effects, which can complicate cancer treatment.

  • Yes (0 points): The patient takes more than three regular medications.
  • No (1 point): The patient takes three or fewer medications.

Self-Perceived Health Status

This question assesses how the patient perceives their health compared to others of the same age.

  • Worse (0 points): The patient feels unhealthier than others their age.
  • Don't know (0.5 points): The patient is uncertain about their health status.
  • As good (1 point): The patient feels about the same as their peers.
  • Better (2 points): The patient feels healthier than most people their age.

Age Factor

Age is a key factor in the G8 questionnaire since older patients generally have higher frailty risks.

  • Older than 85 years (0 points): Highest risk category.
  • 80 to 85 years old (1 point): Moderate risk.
  • Younger than 80 years (2 points): Lower risk category.

The total score from these eight factors determines whether a patient is considered fit for standard cancer treatment or if they require a more detailed geriatric evaluation.

Understanding Your Score

The G8 Questionnaire Calculator provides a total score based on the answers to eight health-related questions. This score helps determine whether an elderly cancer patient is fit for standard treatment or if they require further evaluation to optimize their care. The scoring system is designed to highlight potential frailty and guide healthcare professionals in making informed decisions about cancer treatment options.

Score Interpretation

The G8 score ranges from 0 to 17, with higher scores indicating better overall health and lower scores suggesting increased frailty. The interpretation of the score is as follows:

  • Score ≥ 14: The patient is considered fit for standard oncology treatments. No immediate additional geriatric assessment is required.
  • Score < 14: The patient is considered frail and at a higher risk of complications from cancer treatment. A more detailed Comprehensive Geriatric Assessment (CGA) is recommended to determine the best treatment approach.

In clinical practice, a score below 14 often leads to further geriatric evaluations, which may include nutritional support, physical therapy, medication review, or modifications in cancer treatment plans to minimize risks.

When to Seek Medical Advice

If the G8 score is low, or if the patient experiences significant health challenges such as weight loss, mobility difficulties, or cognitive decline, it is essential to seek medical advice. A healthcare provider can assess whether additional interventions are needed to improve the patient's overall health and treatment readiness.

Signs That Medical Consultation is Needed:

  • Significant weight loss (more than 3 kg in three months)
  • Persistent loss of appetite and difficulty eating
  • Reduced mobility, requiring assistance for daily activities
  • Memory issues, confusion, or signs of depression
  • Taking multiple medications with potential side effects
  • Feeling significantly weaker or less healthy than others of the same age

Even if a patient scores 14 or higher, regular health monitoring is crucial. Cancer treatments can affect elderly patients differently, and ongoing assessments help ensure they receive the best possible care.

If the G8 score is low, a Comprehensive Geriatric Assessment (CGA) can provide a more detailed evaluation. This assessment looks at various aspects of the patient's health, including functional status, cognitive function, nutrition, and social support, to develop a personalized treatment plan.

Conclusion

The Geriatric Oncology G8 Questionnaire Calculator is a valuable tool for assessing the overall health and frailty of elderly cancer patients. By evaluating key factors such as appetite, weight loss, mobility, cognitive function, and medication use, the questionnaire helps identify patients who may require additional support before undergoing cancer treatment.

A G8 score of 14 or higher suggests that the patient is generally fit for standard oncology treatments, while a score of less than 14 indicates a higher level of frailty, warranting a more comprehensive geriatric assessment. This additional evaluation can help healthcare providers tailor treatments to the patient’s needs, reducing risks and improving outcomes.

For caregivers and family members, the G8 Questionnaire provides insights into an elderly loved one’s health status, helping facilitate discussions with medical professionals. It also empowers patients to take a proactive role in their cancer treatment journey, ensuring they receive care that aligns with their overall well-being.

While the G8 Questionnaire is an effective screening tool, it should not replace a full medical evaluation. Patients with a low score or significant health concerns should consult a healthcare professional for further assessment and personalized care planning.

By using the G8 Questionnaire Calculator, patients, caregivers, and healthcare providers can work together to ensure that elderly individuals receive the most appropriate and supportive cancer treatment, improving both quality of life and treatment success.
