According to Gram Research analysis, a new hospital nutrition program called PEAR increased the detection of malnourished patients from 9% to 49% by assigning trained nutrition assistants to monitor food intake, weight, and mealtime support. The program improved staff teamwork, reduced workload stress, and decreased food waste by 7.47 kg, demonstrating that dedicated nutrition care staff can significantly improve how hospitals identify and support patients at risk of malnutrition.
A Canadian hospital tested a new nutrition care program called PEAR (Patients Eating and Recovering) to tackle a major problem: nearly half of hospital patients aren’t getting proper nutrition. The program added trained nutrition assistants to help nurses monitor what patients eat, track their weight, and make sure they get the right food at mealtimes. After launching PEAR, nutrition screening jumped from just 9% to 49% of patients, staff reported better teamwork, and the hospital even reduced food waste. This research shows that having dedicated nutrition support staff can make a real difference in patient recovery and hospital efficiency.
Key Statistics
A 2026 research study of the PEAR nutrition program at a Canadian hospital found that nutrition screening rates increased from 9% to 49% after implementing dedicated nutrition assistants, meaning the hospital identified five times more patients at risk of malnutrition.
The PEAR program reduced food waste by 7.47 kg between pre- and post-implementation measurement days while improving nutrition monitoring consistency and staff satisfaction in acute care settings.
According to the PEAR model research, assigning trained dietitian assistants to nutrition care tasks improved interdisciplinary collaboration and reduced workload pressures on nursing staff while maintaining reliable patient weight and food intake tracking.
The Quick Take
- What they studied: Whether a new nutrition care program could help hospitals better identify and support patients who aren’t eating enough and are at risk of malnutrition.
- Who participated: Staff and patients at an urban Canadian acute care hospital, with a focus on elderly patients in one care unit. The exact number of patients wasn’t specified in the study.
- Key finding: The PEAR program increased nutrition screening from 9% to 49% of patients, meaning hospitals caught malnutrition problems five times more often after the program started.
- What it means for you: If you’re admitted to a hospital using a program like PEAR, you’re much more likely to have your nutrition needs checked and monitored during your stay, which can help you recover faster. However, this study was done at one hospital, so results may vary elsewhere.
The Research Details
Researchers at a Canadian hospital created a new nutrition care program called PEAR and tested whether it worked better than their old system. They measured things before and after launching the program, like how many patients got nutrition screening and how well staff monitored what patients ate. The program added trained nutrition assistants (called DAs) to work alongside nurses and other hospital staff to focus specifically on nutrition care tasks.
The nutrition assistants helped with practical tasks like setting up meal trays, checking on patients’ food preferences, helping with dental care before meals, and positioning patients properly so they could eat safely. The team also made sure to track patient weight regularly and monitor how much food patients actually ate. Before starting, hospital leaders interviewed staff and reviewed patient records to understand what problems needed fixing.
This research approach matters because it tests a real-world solution in an actual hospital setting rather than just in a lab. By measuring specific things before and after (like screening rates and staff satisfaction), researchers could see whether the program actually made a difference. Including patient partners in designing the program meant the solution was built around what patients actually needed, not just what doctors thought they needed.
This study was done at one hospital, so results may not apply everywhere. The study didn’t use a comparison group (like another hospital without the program), which means some improvements might have happened anyway. However, the large jump in screening rates (from 9% to 49%) is substantial enough to suggest the program made a real difference. Staff satisfaction and reduced food waste provide additional evidence that the program worked well.
What the Results Show
The PEAR program dramatically improved how hospitals catch nutrition problems. Before the program, only 9% of patients received nutrition screening, meaning most patients at risk of malnutrition went undetected. After PEAR launched, this jumped to 49%, meaning the hospital identified five times more patients who needed nutrition support.
Beyond screening, the program made nutrition monitoring much more consistent. Instead of nutrition care being scattered across different staff members with unclear responsibilities, the nutrition assistants created a reliable system for tracking what patients ate and how much weight they gained or lost. Staff reported that workflows became clearer and teamwork improved because everyone understood their role in nutrition care.
The nutrition assistants proved to be essential team members. They identified patients at highest risk of malnutrition and worked directly with nurses to support mealtime care. This freed up nurses to focus on other critical tasks while ensuring nutrition didn’t fall through the cracks. The program also had unexpected benefits: food waste decreased by 7.47 kg between measurement days, saving money and reducing environmental impact.
Staff satisfaction improved significantly after PEAR launched. Nurses and other hospital workers reported feeling less overwhelmed and stressed about nutrition care because responsibilities were clearer and better organized. The program also strengthened teamwork between different departments, dietitians, nurses, nursing assistants, and other staff communicated better about patient nutrition needs. This kind of improved collaboration often leads to better overall patient care, though the study didn’t measure patient outcomes directly.
Malnutrition in hospitals has been a known problem for years, and previous research shows it leads to longer hospital stays, more complications, and higher death rates. Most hospitals struggle with nutrition screening and monitoring because these tasks often get deprioritized when staff are busy. The PEAR program addresses this by making nutrition care a dedicated responsibility rather than an add-on task. The dramatic improvement in screening rates (from 9% to 49%) suggests this approach works better than traditional models where nutrition care is scattered among many staff members.
This study was conducted at only one hospital, so results may not apply to all hospitals or different types of care settings. The study didn’t include a comparison hospital without the PEAR program, so we can’t be completely certain that all improvements were due to PEAR rather than other changes happening at the same time. The study didn’t measure whether patients actually recovered faster or had fewer complications, it measured whether nutrition care processes improved, which is important but not the same as measuring patient health outcomes. The exact number of patients involved wasn’t clearly reported, making it harder to understand the full scope of the program’s impact.
The Bottom Line
Hospitals should consider adopting nutrition care models like PEAR that assign dedicated staff to nutrition screening, monitoring, and support. The evidence is strong that this approach catches malnutrition problems much more often (screening increased five-fold). Staff training and clear role definitions are essential for success. This recommendation is appropriate for hospitals with similar resources and patient populations, though individual hospitals should adapt the model to their specific needs.
Hospital administrators and nutrition departments should care about this research because it shows a practical way to improve nutrition care and staff satisfaction. Patients, especially elderly patients and those with serious illnesses, should care because better nutrition screening and monitoring can improve their recovery. Insurance companies and healthcare systems should care because malnutrition increases hospital costs through longer stays and more complications. However, this study was done at one Canadian hospital, so hospitals in different regions or with different patient populations should evaluate whether PEAR would work in their setting.
Improvements in nutrition screening and monitoring appeared immediately after PEAR launched, suggesting the program works quickly. However, seeing improvements in patient health outcomes (like faster recovery or fewer complications) would likely take longer, probably weeks to months, because nutrition’s effects on healing take time. Staff satisfaction improvements also appeared relatively quickly, within the timeframe of the study.
Frequently Asked Questions
What is malnutrition in hospitals and why is it a problem?
Malnutrition in hospitals occurs when patients don’t eat enough or get proper nutrition during their stay. It affects nearly half of Canadian hospital patients and causes longer hospital stays, more complications, and higher death rates. The PEAR program addresses this by improving nutrition screening and monitoring.
How much did the PEAR program improve nutrition screening?
The PEAR program increased nutrition screening from 9% to 49% of patients, a five-fold improvement. This means the hospital caught malnutrition problems in five times more patients after the program launched, helping identify at-risk patients much earlier.
What do nutrition assistants do in the PEAR program?
Nutrition assistants monitor what patients eat, track their weight, set up meal trays, check food preferences, help with dental care before meals, and position patients properly for eating. They work with nurses to ensure nutrition care is consistent and reliable throughout the hospital.
Did the PEAR program help hospital staff feel less stressed?
Yes, staff reported clearer workflows, stronger teamwork between departments, and reduced workload pressures after PEAR launched. Having dedicated nutrition assistants freed up nurses to focus on other tasks while ensuring nutrition care wasn’t neglected.
Can other hospitals use the PEAR program?
The PEAR program was tested at one Canadian hospital, so results may vary in different settings. Other hospitals should evaluate whether they have similar resources and patient populations. The program’s core idea, assigning dedicated staff to nutrition care, appears effective and could be adapted to different hospital environments.
Want to Apply This Research?
- Users admitted to hospitals should track their daily food intake and weight using the app. Specifically, log what percentage of meals they eat (25%, 50%, 75%, 100%) and record weight daily if possible. This creates a record that hospital staff can review to identify nutrition problems early.
- When admitted to a hospital, users should proactively ask staff about nutrition screening and request that their food intake be monitored. If the hospital uses a program like PEAR, users can work with nutrition assistants to communicate food preferences, dental concerns, or positioning needs that affect their ability to eat safely.
- Long-term, users recovering from hospitalization should continue tracking their weight and appetite for 2-4 weeks after discharge. The app can send reminders to eat regular meals and track whether appetite and energy levels are improving, which indicates nutrition recovery is on track.
