A multicenter study of 1,023 cancer patients across 13 Portuguese hospitals found that implementing a simple nutrition screening protocol increased nutritionist visits by 20.2% and reduced wait times for high-risk patients by 43.2%. According to Gram Research analysis, nurses using a validated screening tool at initial appointments successfully identified 55% of patients as nutritionally at-risk, enabling faster intervention and better coordination between doctors, nurses, and nutrition specialists.
Cancer patients often struggle with poor nutrition, which can make their treatment less effective and hurt their quality of life. Most hospitals don’t regularly check if cancer patients are getting enough nutrition, even though guidelines say they should. Researchers in Portugal tested a new system where nurses screen cancer patients for nutrition problems at their first visit. They found that when hospitals use this screening system, more patients get help from nutritionists, and patients who need urgent help get it much faster. According to Gram Research analysis, this approach works well but hospitals need more staff and time to make it happen regularly.
Key Statistics
A 2026 multicenter study of 1,023 cancer patients across 13 Portuguese hospitals found that implementing a nutrition screening protocol increased nutritionist consultations by 20.2% and decreased waiting times for high-risk patients by 43.2%.
Among 1,023 cancer patients screened using the NRS-2002 tool, 55% were identified as at nutritional risk, with the most common problems being nutrition impact symptoms, weight loss, and reduced food intake.
A survey of 60 healthcare professionals (21 oncologists, 23 nurses, and 16 nutritionists) implementing the nutrition screening protocol reported improved multidisciplinary coordination and enhanced training outcomes.
The nutrition screening protocol was successfully implemented across 13 hospitals in Portugal over a four-month period, demonstrating feasibility in routine oncology care despite time constraints and staffing limitations.
The Quick Take
- What they studied: Whether a simple nutrition screening system for cancer patients actually works in real hospitals and what doctors and nurses think about using it
- Who participated: 60 healthcare workers (21 doctors, 23 nurses, and 16 nutrition specialists) from 13 hospitals in Portugal screened 1,023 cancer patients over four months
- Key finding: When hospitals used the screening system, nutritionist visits increased by 20.2% and wait times for urgent patients dropped by 43.2%, meaning patients got help much faster
- What it means for you: If you’re getting cancer treatment, your hospital may soon screen you for nutrition problems at your first visit. This could help you get nutrition support faster and feel better during treatment. However, this only works if hospitals have enough staff to run the program
The Research Details
Researchers created a simple nutrition screening system and tested it at 13 hospitals in Portugal. Nurses used a checklist called NRS-2002 to identify cancer patients who weren’t eating well or had lost weight. The system looked for warning signs like trouble eating, weight loss, and reduced food intake. After running the screening for four months, the researchers asked 60 healthcare workers (doctors, nurses, and nutrition experts) what they thought about the system. They also brought together a group of nutrition experts to discuss the best ways to make nutrition care a regular part of cancer treatment at all hospitals.
Many cancer patients become malnourished, which makes their bodies weaker and treatments less effective. However, hospitals often miss these nutrition problems because they don’t have a regular system to check for them. By testing a simple screening system, researchers could show that hospitals can catch nutrition problems early without making extra work for staff. This helps prove that nutrition care should be part of standard cancer treatment everywhere.
This study included real patients and real healthcare workers from multiple hospitals, which makes the findings more trustworthy than a single hospital study. The researchers used a validated screening tool (NRS-2002) that experts already trust. The study measured concrete improvements like wait times and number of visits, not just opinions. However, the study only included hospitals in Portugal, so results might be different in other countries with different healthcare systems.
What the Results Show
When the screening system was put in place, 55% of the 1,023 cancer patients screened were found to be at nutrition risk. This shows that nutrition problems are very common in cancer care. After the screening system started, nutritionist visits increased by 20.2%, meaning more patients got professional nutrition help. Even more importantly, wait times for patients identified as high-risk dropped by 43.2%, which means urgent patients got help much faster. Healthcare workers reported that the screening system improved teamwork between doctors, nurses, and nutritionists. Nurses were the main people doing the screening during patients’ first appointments, which worked well because nurses see patients early in their treatment.
The most common nutrition problems found were eating difficulties, weight loss, and reduced food intake. When patients were identified as at-risk, the most common treatments were referrals to a nutrition specialist and oral nutritional supplements (drinks or shakes that provide extra calories and nutrients). Healthcare workers said the screening system helped them coordinate better as a team and gave them better training on nutrition issues. The study showed that implementing this system is possible in busy hospitals without completely disrupting normal operations.
Previous research has shown that malnutrition is common in cancer patients and hurts treatment outcomes, but most hospitals don’t screen for it regularly. This study is important because it shows that a simple, practical screening system can actually be used in real hospitals and makes a real difference. The findings support what nutrition guidelines have been recommending for years: that early screening and intervention help cancer patients. This research provides evidence that hospitals should make nutrition screening a standard part of cancer care, not an optional extra.
The study only included hospitals in Portugal, so the results might not apply to hospitals in other countries with different healthcare systems or resources. The study asked healthcare workers what they thought happened, rather than measuring some outcomes independently, which could introduce bias. The study was relatively short (four months), so it’s unclear if hospitals can keep the screening system running long-term. The study didn’t measure whether better nutrition actually improved patient outcomes like treatment success or quality of life, only whether more patients got nutrition help.
The Bottom Line
Cancer patients should ask their healthcare team about nutrition screening at their first appointment. Healthcare workers should implement a simple nutrition screening system using validated tools like NRS-2002. Hospitals should assign nurses to do the screening during initial visits. Hospitals should ensure patients identified as at-risk get quick referrals to nutrition specialists. These recommendations have strong support from this research but require hospitals to commit resources and staff training. Confidence level: Moderate to High for feasibility; Moderate for long-term outcomes.
Cancer patients and their families should care about this because it could help them get nutrition support faster. Oncologists, nurses, and hospital administrators should care because it shows a practical way to improve cancer care. Nutrition specialists should care because it increases their role in cancer treatment. People without cancer don’t need to apply these findings to themselves, but the approach might work for other serious illnesses.
Hospitals that implement screening should see increased nutritionist visits within weeks and faster wait times within one to two months. Cancer patients should expect to be screened at their first appointment if their hospital uses this system. Improvements in how well patients feel and how well treatment works would take longer to measure, likely several months.
Frequently Asked Questions
Do cancer patients need nutrition screening during treatment?
Yes. Research shows 55% of cancer patients are at nutritional risk. A 2026 study found that screening at initial appointments increased nutritionist visits by 20.2% and reduced wait times by 43.2%, helping patients get support faster when they need it most.
What nutrition problems do cancer patients commonly have?
The most common issues are eating difficulties, weight loss, and reduced food intake. These occur in over half of cancer patients and can weaken the body and reduce treatment effectiveness. Early screening helps identify these problems before they become severe.
How can hospitals make nutrition care part of regular cancer treatment?
Hospitals can implement a simple screening system where nurses check patients at their first visit using a validated tool. When patients are identified as at-risk, they get quick referrals to nutrition specialists. This approach worked across 13 hospitals in Portugal and improved care coordination.
What treatments help cancer patients with nutrition problems?
The most effective interventions are referrals to clinical nutritionists and oral nutritional supplements (fortified drinks or shakes). A 2026 study found these approaches, combined with early screening, significantly improved access to nutrition support for cancer patients.
Can nutrition screening work in busy hospitals?
Yes, but it requires support. A 2026 study showed screening is feasible in 13 hospitals, though healthcare workers reported time constraints and insufficient staff as main challenges. Hospitals need to commit resources and training to make it sustainable long-term.
