When a dietitian joined the lung ward every morning, three in four patients got checked for malnutrition. When the job went back to the nurses, it fell to four in ten

Most people who go into hospital are never seen by a dietitian. In many countries, Denmark among them, the job of spotting who is eating too little sits with the nurses: weigh the patient, ask about appetite and recent weight loss, score the answers, and call in a dietitian if the score is high. Nurses are also doing the medicines, the dressings, the call bells and the discharges, and study after study finds that the nutrition check is the task that slips. That matters because people who are undernourished in hospital stay longer, recover worse and are more likely to die.

A team at Gødstrup Hospital in Herning, Denmark, tried moving the job. On a 27-bed lung ward, from March 2022 to July 2023, a clinical dietitian was on the ward every day from 7 in the morning to 2.30 in the afternoon, weekends and holidays included. The dietitian did the malnutrition screening for every patient expected to stay two days or more, wrote the nutrition plans, sat in on the nurses' meetings and helped patients order their meals from the ward's tablet menu. Nurses kept everything else, including helping people eat. The hospital did this partly because it was short of nurses. The results were published in the Journal of Human Nutrition and Dietetics on 8 October 2026.

The screening numbers are the clearest part. The researchers pulled the records of 1,678 admissions that lasted more than 48 hours, across the dietitian period and the 11 months after it, when the work went back to the nurses. In a typical month with dietitians in charge, 55% of patients were screened within the first 24 hours, as the hospital's own rules require, and 76% were screened at some point. Once nurses had it again, the monthly figures settled at 29% and 43%. On the month-by-month chart the change shows up as a clear shift, not a slow drift.

Then the food. Among patients already flagged as at risk, the team counted what 32 people actually ate over their first three days, using the electronic meal ordering system plus a check with each patient. They compared them with 68 similar patients on the same ward from an earlier study, when nurses ran nutrition care with the same menu system. Nearly eight in ten of the dietitian group (79%) got at least three quarters of the calories they needed, against 57% before (p = 0.023), after allowing for sex, age, body weight and risk score. For protein the gap was smaller, 50% against 35%, and could be chance.

That intake comparison is the weak link, and the authors say so. The control patients were recorded at an earlier time, the hospital has moved to a new building since, and there is no record of how many control patients were invited or said no. The two groups' needs were worked out differently too: dietitians used a formula, while the nurses earlier used standard tables, so 'three quarters of what they needed' does not mean exactly the same thing in both. When the team recalculated everyone's needs the same way, the gap held in direction but narrowed to 76% against 59%, right on the edge of chance (p = 0.052). Their own after-the-fact calculation says proving the protein difference would have taken about 263 and 124 patients, not 68 and 32. They call the findings hypothesis-generating, which is the honest label.

The interviews are what make the paper worth reading. Nine nurses and all five dietitians were asked how it went. Nurses talked about relief: 'nutrition sometimes ends up getting lost among all the other tasks', one said. Having the dietitian on the ward turned an outside expert you phone into a colleague you can tap on the shoulder. But some nurses said they lost their feel for what patients were really eating, and there were collisions, such as breakfast ordered for 8 o'clock when the nurse who had to help the patient eat was still giving out medicines. The dietitians found the work meaningful, but at least one found it hard to be the first person into the room of a very sick patient each morning, and none wanted the ward to be their whole job.

Some of this needs care in reading. The screening comparison runs backwards, dietitians first and nurses after, so it cannot show what nurses managed before anyone intervened, and the authors chose that on purpose because an earlier project on the ward may have raised nurses' attention to food. The model also added a person with protected time, so it tests 'a dietitian on the ward every day' as much as 'dietitians instead of nurses'. Patients in the dietitian period went home sooner (median 4 days against 6), but the study was not built to test length of stay, readmissions or deaths, and it does not claim any of those. It is one ward in one hospital.

What stays with us is the simple point under the numbers: when nutrition is somebody's whole job for the morning, it gets done, and when it is one more box on a busy nurse's list, it often does not. If you or someone you care for goes into hospital, especially an older person or someone who has been eating poorly or losing weight, it is reasonable to ask whether they have been screened for malnutrition and whether a dietitian can see them. Asking costs nothing, and on a busy ward it may be the nudge that gets it done.
