Nutrition Risk Screening Software

Protein-calorie malnutrition has been recognized as a nutritional problem in the healthcare setting since the mid 1970s, when research began to demonstrate that up to half of hospitalized patients were at risk for malnutrition (1) and up to 12% were severely malnourished. (2) Malnourished patients are hospitalized up to 100% longer than patients with comparable  diagnoses who are well nourished, and expenses for malnourished patients average 75% higher than their well-nourished counterparts. (3)

Healthcare experts recognize the role of proactive nutrition intervention in reducing morbidity and mortality, reducing length of stay and associated expenses, and most importantly, promoting quality of care and quality of life for individuals receiving medical care. While nutrition screening evolved as a means to identify protein-calorie malnutrition, today it has broad applications in identifying patients who can benefit from nutritional care.

Proactive InterventionThe American Dietetic Association (ADA) defines nutrition screening as: “the process of identifying patients, clients, or groups who may have a nutrition diagnosis and benefit from nutrition assessment and intervention by a registered dietitian (RD).” Nutrition screening lies outside the steps of the nutrition care process as defined by ADA. It can be the trigger that sets the nutrition care process into motion. A positive nutrition risk screen can be the impetus for nutritional assessment, which leads to identification of nutrition problems and development of nutrition interventions.

Continually screening every patient’s nutritional risk and implementing proactive nutritional interventions on a timely basis are key to quality healthcare. This is why Joint Commission standards require nutrition screening within 24 hours of admission.

Nutrition Screening Practices

Nutrition Screening Practices Today

Screening PracticesSurprisingly, Chima and colleagues (Nutrition Risk Screening in Acute Care: A Survey of Practice, August 2008) found, in a survey of clinical nutrition managers in the ADA Clinical Nutrition Management Dietetic Practice Group, that only 4% were using a computerized system to “automatically generate notification of at-risk patients based on established criteria without human intervention.”

Nutrition Screening Criteria

Listed in order of popularity

  • History of weight loss
  • Poor intake prior to admission
  • Patient is on nutrition support
  • Chewing/swallowing issues
  • Skin breakdown
  • Pregnant/lactating
  • Diagnosis
  • Need for education
  • Geriatric surgical patient
  • Specific diet orders
  • Food allergy
  • NPO/clear liquid
  • Weight for height criterion
  • Age
  • Visceral proteins (albumin, prealbumin)
  • Infant on concentrated formula
  • Body mass index

They also noted that 84% of survey respondents said that nursing staff carry primary responsibility for nutrition screening. However, respondents also said that nutrition staff repeat the nutrition screening due to issues such as patients being missed, nursing screenings not being done, or nutrition staff not being notified of positive nutrition risk screening results. Only 23% of nutrition screens were being documented in a computer-based medical record. These findings underscore the importance of automating nutrition risk screening, applying technology to ensure consistent applications and notification.

Using HL7 interfaces, the Nutritional Risk Screening Tool accepts data from hospital A/D/T, order entry, laboratory, and pharmacy systems. The screening reports show all patients in the hospital who meet the nutritional risk criteria established by the facility. Appropriate patient information (name, room number, diet type, diagnosis, etc.) is shown, as well as the specific risk criteria that have been met. This builds a set of real-time data.

The next step is to apply a model for analyzing data relevant to nutrition data. A variety of models exist. According to Chima and colleagues, “Because there is no national consensus or gold standard regarding nutrition risk, screening practice and criteria vary.”

Some systems use scoring, while others classify patients into one of two or three risk categories. Opportunities for enhanced nutrition informatics exist in that clinical outcomes from nutrition screening and support vary according to many other factors, such as age, severity of nutrition screening score, and diagnosis.

Nutrition Screening Tools

Nutrition Screening Tools

Nutrition Screening ToolsToday, a variety of standardized tools for nutrition screening are in use:

  • Nutritional Risk Screening 2002 (NRS 2002) scores risk based on undernutrition and severity of disease. Scoring is on a scale of 1 to 6. A score of 3 is classified as nutritionally at-risk.
  • Mini Nutritional Assessment (MNA) is a short questionnaire designed for use with the elderly.
  • Malnutrition Screening Tool (MST) uses only two questions, addressing appetite and recent unintentional weight loss. Scoring is on a scale of 0 to 5, with 2 or more indicating nutrition risk.

Malnutrition ScreeningRegardless of the criteria applied in any healthcare organization, routine nutrition screening is a cornerstone of quality healthcare. Technology can help. The Vision Software nutrition risk screening application is customizable to your institution’s interpretive standards. It reliably collects designated data, performs calculations, applies algorithms, and flags patients at risk per established standards.

Clinical nutrition staff can use the Vision Nutritional Risk Screening report to prioritize work. They can become more productive, performing assessments and creating care plans for patients who may benefit from their expertise and interventions. As part of quality of care and informatics initiatives, Vision Software provides electronic documentation of nutrition findings as well.
