Gram Research analysis shows that a new three-part online screening tool is being tested to predict which cancer surgery patients will have complications after their operation. The tool asks patients about their physical fitness, nutrition, and mental health before surgery. In this international study of 1,214 patients across 35 hospitals, researchers aim to determine if this simple screening can identify high-risk patients early enough for doctors to provide extra support before surgery, potentially reducing serious complications and helping hospitals use limited resources more fairly.
Researchers are testing a simple online screening tool to help doctors identify which cancer patients are at highest risk for complications after surgery. The tool asks patients three types of questions about their physical fitness, nutrition, and mental health. By catching high-risk patients early, doctors can provide extra support before surgery, which may reduce serious complications. This international study involves over 1,200 patients across 35 hospitals in 19 countries and could help hospitals use their resources more fairly and effectively.
Key Statistics
A 2026 international cohort study of 1,214 gastrointestinal cancer surgery patients across 35 sites in 19 countries is evaluating a three-part online screening tool to predict postoperative complications within 30 days of surgery.
The screening tool combines three validated questionnaires measuring physical fitness, nutritional status, and mental health, available in English, Spanish, French, and Portuguese to reach diverse patient populations.
The study will track not only surgical complications but also hospital length of stay, readmission rates, and 12-month survival to comprehensively evaluate whether the screening tool improves overall patient outcomes.
The Quick Take
- What they studied: Whether a three-part online screening tool can accurately predict which patients will have problems after gastrointestinal cancer surgery
- Who participated: 1,214 adults having planned gastrointestinal cancer surgery at 35 hospitals across 19 countries, completing an online questionnaire before their operation
- Key finding: The study is currently recruiting participants and will measure whether the screening tool successfully identifies high-risk patients within 30 days after surgery
- What it means for you: If this tool works, your doctor could identify surgery risks before your operation and provide extra preparation to help you recover better. This is especially helpful for hospitals with limited resources.
The Research Details
This is a prospective cohort study, which means researchers will follow patients forward in time from before surgery through recovery. Patients will complete an online screening tool before their operation that asks about three areas: how physically active they are, their nutrition status, and their mental health. The researchers selected these three areas based on a thorough review of existing research and input from international experts who voted on which questions were most important.
The screening tool combines three well-established questionnaires: the Duke Activity Status Index (which measures fitness), the Patient-Generated Subjective Global Assessment Short Form (which evaluates nutrition), and the Patient Health Questionnaire-4 (which screens for depression and anxiety). The tool is available in English, Spanish, French, and Portuguese to reach patients across different countries.
After surgery, researchers will track what happens to each patient for 30 days and then follow up again at 12 months. They’ll record whether patients had complications, how long they stayed in the hospital, whether they were readmitted, and whether they survived.
Most hospitals don’t have enough resources to give all cancer surgery patients intensive preparation programs before surgery, even though these programs can help prevent complications. This screening tool could solve that problem by quickly identifying which patients need the most help, allowing hospitals to focus their limited resources on patients who need them most. The tool is also fast and online, which is important because cancer patients often need surgery quickly after diagnosis.
This study has strong design features: it’s international (35 sites in 19 countries), it uses well-validated questionnaires that have been tested in previous research, and it was approved by ethics committees. The researchers carefully selected their screening questions through a systematic process including expert consensus. However, because this is a protocol paper, the actual results haven’t been published yet, so we don’t know if the tool actually works as intended.
What the Results Show
This paper describes the study plan rather than results, as the research is still ongoing. The primary outcomes the researchers will measure include: the rate of postoperative complications (any problems after surgery), major complications (serious problems requiring intervention), and overall complication severity using a standardized scale called the Comprehensive Complications Index.
The study will examine whether the three-part screening tool can accurately separate patients into different risk groups—those at low, medium, and high risk for complications. Researchers will determine the best cutoff scores on each part of the tool that best predict which patients will have problems.
They will also test whether the screening scores remain predictive even after accounting for other known risk factors like age, weight, and existing medical conditions. This is important because it shows whether the screening tool adds new information beyond what doctors already know.
Beyond complications, the study will also track hospital length of stay (how many days patients stay in the hospital), readmission rates (how many patients return to the hospital within 30 days), where patients go after discharge (home versus other facilities), the number of days patients spend at home and alive in the first 30 days, 30-day mortality (death rate), and 12-month survival. These outcomes help paint a complete picture of how the screening tool relates to overall recovery and quality of life.
Previous research has shown that prehabilitation—preparing patients physically, nutritionally, and mentally before surgery—can reduce complications. However, most hospitals can’t offer this to all patients due to cost and time constraints. This study builds on that evidence by testing whether a simple screening tool can identify which patients would benefit most from targeted preparation. The three-part approach (physical, nutritional, psychological) reflects current understanding that surgery recovery involves the whole person, not just physical fitness.
This is a protocol paper describing the study plan, not the results, so we don’t yet know if the tool actually works. The study is limited to patients having planned (elective) surgery, so results may not apply to emergency cancer surgeries. The tool relies on patient self-reporting, which can be less accurate than objective medical tests. Additionally, the study measures outcomes only up to 30 days after surgery and 12 months, so longer-term effects are unknown. Finally, while the study is international, it may not represent all populations equally.
The Bottom Line
This study is still in progress, so specific clinical recommendations cannot yet be made. However, the research approach is sound and addresses a real clinical need. Once results are available, hospitals should consider implementing the screening tool if it successfully predicts complications, as it could help allocate resources fairly and improve patient outcomes. Patients undergoing gastrointestinal cancer surgery should discuss with their doctors whether they might benefit from preoperative preparation based on their individual risk factors.
This research is most relevant to: patients scheduled for gastrointestinal cancer surgery (stomach, colon, pancreas, liver, or esophageal cancer), surgeons and surgical teams, hospital administrators managing limited resources, and cancer care centers. It’s less relevant to patients having emergency surgery or those with very early-stage cancers not requiring surgery.
The study is currently recruiting patients and will continue through 2026-2027. Results should be available in 2027-2028. If the tool proves effective, implementation in hospitals could begin within 1-2 years after publication. Patients would see benefits immediately if their hospital adopts the tool, as it would help identify those needing extra preoperative support.

Want to Apply This Research?
- Track your physical activity level (minutes of moderate activity per week), daily nutrition intake (servings of protein, fruits, vegetables), and mood/anxiety symptoms (using a simple daily mood scale 1-10) for 4-6 weeks before planned surgery. This mirrors the three domains of the screening tool.
- Use the app to complete the three-part screening questionnaire 2-4 weeks before surgery, then follow personalized recommendations for physical activity, nutrition improvements, and stress management. Share results with your surgical team to discuss whether additional preoperative preparation would help.
- Log weekly check-ins on fitness (can you walk further or climb stairs easier?), nutrition (are you eating more protein?), and mental health (do you feel less anxious?). Track these improvements through surgery and recovery to see which areas helped you recover best.
