Clinical Nutrition and Dietetics Case Studies
Healthcare5 Case StudiesUpdated Sep 2026
Clinical nutrition sits where bedside observation, measurement and ward routine overlap, so small signals are easy to lose. The five cases below come from settings where dietetic input, nursing observations, medical review and administrative systems all touch the same patient. Each asks a practical question: what did the team know, what should they have done with it, and which protocol or handover step shaped the outcome. The organizations are fictional, but the pressures are familiar. Read each case as a team member would, tracking who held which information and when, before turning to the analysis.
Case Study 1
A slow slide in intake on a medical ward
Ridgeway Memorial Hospital, a 310 bed acute care hospital with a shared medical ward and a standing dietetic referral service
The situation
Walter, a 74 year old retired machinist, was admitted to the medical ward of Ridgeway Memorial Hospital after a fall at home. In the first two days his meal charts showed him eating about half of most trays, and the nurses noted that he had become quieter and less willing to leave his bed. His malnutrition screen was completed on admission and not repeated until the weekly review. Delia, the night charge nurse, flagged the falling intake in a handover note. The day team read it as recovering fatigue and planned to reassess after physiotherapy. Nobody connected the change to the weight trend that Priya, the dietitian, had asked to see.
The challenge
The team had three sources of information that pointed in different directions. Intake records suggested a decline, the fatigue explanation was plausible for a man recovering from a fall, and the weight trend lived on a separate chart that most day staff did not open. The protocol for nutritional deterioration set a review trigger when intake stayed below half for consecutive days, but nobody had counted the days. The question was which signal should drive investigation and when escalation became necessary.
Analysis
Walter's needs were both nutritional and functional. A man who has fallen, is eating poorly, and is becoming withdrawn may be signaling several problems at once, and the team's record showed evidence for each without showing how they related. The intake charts were the most direct evidence, the screening score was out of date, and the weight trend was the signal the dietitian had requested. Good practice here means treating the trend as the primary evidence and the fatigue explanation as one hypothesis, not the default. Reassessing the screen on the day intake fell would have given the team a current score to weigh against the handover note.
Teams grounded in Clinical Nutrition and Dietetics tend to start by asking who owns each signal. Here the nurses owned the intake charts, the dietitian owned the weight trend and screening follow up, and the medical team owned the decision to change the plan. Delia's handover note reached the day team, but it did not name the protocol trigger or the person responsible for reviewing it. Local protocol placed the first escalation decision with the ward team once the threshold was met, and that threshold was never checked. A shared line in the handover, naming the trigger and the reviewing role, would have turned an observation into a task.
- Review symptom change Compare intake charts, weight trend and handover notes against each other.
- Prioritize investigations Choose the checks that would change the plan, and name who completes each.
- Apply escalation threshold Check the protocol trigger, count the days, and escalate when it is met.
- Hand over and reassess Record the trigger, reviewing role and due time in the shared handover.
Actions taken
- Add a daily intake review to the ward huddle, with the nurse in charge recording whether intake has stayed below the protocol threshold for the required number of days.
- Require the dietitian's current screening score and weight trend to be displayed on the ward summary screen, so day staff see them without opening a separate chart.
- Change the handover template so that every nutrition concern names the protocol trigger, the reviewing role, and the time by which the review is due.
- Run a six week audit of admissions with a falling intake flag, recording how many reached a documented review within the protocol timeframe, and report the result at the monthly quality meeting.
Results
After the handover template changed, the ward ran the audit over the following weeks. Of 46 admissions flagged for falling intake, 31 reached a documented dietetic review within the protocol timeframe, compared with 12 of 40 in the period before the change. Walter's review took place on the second day after the flag, and the team revised his plan with the dietitian present. The ward's staff survey showed that most day nurses could state the trigger without checking the policy. The team agreed to keep the audit running for another quarter before deciding whether the change was embedded.
Questions for discussion
- Which signal in this case should have carried the most weight on the day intake first fell, and why?
- How would you redesign the handover so that a trend across several days is visible to a team that rotates shifts?
- When a protocol trigger has been met but no one has counted the days, whose responsibility is the check?
Case Study 2
A handover gap after an afternoon transfer
Lakeshore Regional Medical Center, a 420 bed teaching hospital with four adult medical wards and a central discharge office
The situation
Marcus, a 58 year old man with a long history of weight loss, was moved from the surgical assessment unit to a medical ward at the end of a busy afternoon. His nutrition plan had been changed twice during the day after the dietitian, Ines, reviewed his intake and asked for a higher level of monitoring. The handover from the outgoing nurse was given verbally at the bedside, and the written summary listed the earlier plan rather than the latest one. The receiving nurse, Owen, worked from the summary because the electronic record had not yet refreshed. Two of the monitoring tasks were therefore missing from the ward schedule for the evening.
The challenge
The gap was not a single error. The verbal handover was accurate, the written summary was out of date, and the schedule was built from the summary. Nobody had a complete picture of which changes were active, which had been discussed but not ordered, and which had been started by the dietitian and not yet confirmed by the medical team. The ward's handover policy allowed a verbal handover with a written follow up, but did not say which document was authoritative when they disagreed.
Analysis
Marcus's needs changed on the same day his handover was prepared. His weight history and recent intake records were the evidence that justified the higher monitoring level, so any loss of that information during transfer loses part of the reason for the plan. The record showed that the dietitian's review had identified a concern, but the concern had to survive three steps: the verbal account, the written summary and the ward schedule. Each step was a place where evidence could be simplified or dropped. Reading the case through the patient's data, rather than through the paperwork, shows how far the gap reached.
A handover is a coordination task, and the ward's protocol treated it as one by requiring both a verbal report and a written summary. The weakness lay in the absence of a rule about authority. Owen had no reliable way to know the summary was stale, and the outgoing nurse assumed the electronic record would update before the transfer. Sound coordination here would name one source of truth for active monitoring tasks and state what happens when sources disagree. Because the protocol required neither, each person made a reasonable choice that together produced a missed task.
Actions taken
- Make the active nutrition plan, including every monitoring task, a required element of the nursing handover form, with the time of the last change recorded.
- Define in policy that the electronic record is authoritative for active orders, and that a written summary must be checked against it before the bedside handover begins.
- Hold a brief two person check at the bedside for any patient whose nutrition plan changed within the previous shift, with the receiving nurse reading back each monitoring task.
- Audit transfers over one quarter for omitted monitoring tasks, and report the count to the ward governance group alongside the number of checks completed at the bedside.
Results
The ward adopted the revised handover form and the bedside check in the following month. In the quarter after the change, the audit found 9 omitted monitoring tasks across 214 transfers, down from 23 across a comparable number in the quarter before. Marcus's monitoring was restored within the first evening after the review, and the dietitian confirmed the plan with the medical team the next morning. The governance group asked for the audit to continue, and it added a question about whether the bedside check was completed when the transfer happened out of hours.
Questions for discussion
- Which document in this case should have been treated as the authority for active monitoring tasks, and what evidence would support that choice?
- How would a verbal handover and a written summary need to differ in content so that each catches what the other misses?
- What would you expect a receiving nurse to do differently if the handover had named the dietitian as the source of the latest change?
Case Study 3
Choosing triage options during a dietetic referral backlog
Pinecrest Community Health Network, three community clinics and one outpatient dietetic service serving 62,000 residents
The situation
Pinecrest's outpatient dietetic service received referrals from the three clinics, the hospital discharge team and two specialist nurses. In the busiest month the referral list grew to 340 people waiting for a first appointment, while the service had the equivalent of 4.5 full time dietitians. Waiting times had lengthened for everyone, including people with recent weight loss and people with swallowing difficulties at home. Kwame, the service manager, had to decide how to protect the most urgent patients without leaving the rest of the list untouched for months. Two options were already on the table, and the decision had to be made before the next intake cycle.
The challenge
Every option moved demand somewhere else. A stricter triage rule would shorten the queue for the highest risk patients but could leave people with early signs unseen for weeks. Fixed weekly clinic slots would give predictability but would waste capacity when referrals were slow. Shifting some reviews to a nurse led telephone pathway would free dietitian time, but only if the nurses had the training and the referral criteria to make safe decisions. The service had to protect care quality while the numbers kept rising.
Analysis
The first question is which patients carry the greatest risk from delay, and the answer depends on evidence the service already holds. Referral forms included weight history, reported intake, and the reason for referral, but the forms were not scored consistently across the three clinics. A patient with recent unplanned weight loss and a patient who wanted advice about a long term eating pattern were sitting in the same queue. Patient need should set the order of review, so the first step is a shared risk screen that every referral passes through before it is placed on a list. Without that, any scheduling option moves the uncertainty around.
Coordination across the clinics and the nurse team is where the options differ most. A stricter triage rule depends on a written protocol that all three clinics apply the same way, and on a named clinician who can override it when a referral looks wrong. Telephone triage needs an agreed escalation route back to a dietitian and a limit on what nurses decide alone. Scheduling changes need the clinics to agree on how many slots they will release each week. The service's existing escalation protocol gave the service manager authority to change clinic allocation for a set period, so the change could be tested before it became permanent.
Actions taken
- Introduce a single risk screen at referral, scored the same way by all three clinics, so that urgency is decided on the same evidence wherever the referral starts.
- Hold back a fixed share of each week's slots for urgent review, and release unused urgent slots to routine referrals on the day before clinic.
- Pilot the nurse led telephone pathway for stable routine referrals only, with written criteria, a named dietitian for escalation, and a weekly review of every decision the nurses make.
- Set a review point after one quarter that compares waiting times and missed high risk referrals against the current baseline before any option is made permanent.
Results
The service combined the shared risk screen with a reserved urgent slot and a pilot of the nurse led pathway for stable routine referrals. Over the following quarter, the average wait for routine referrals fell from 11 weeks to 7 weeks, and no high risk referral in the pilot waited beyond the urgent window. Two nurse decisions were escalated to a dietitian and both were confirmed. The steering group extended the pilot to a second clinic and kept the urgent slot in place, while agreeing to revisit the weekly slot share at the next review.
Questions for discussion
- Which of the three options would you trust least if the referral criteria were applied differently at each clinic, and why?
- How should a service decide how many urgent slots to hold back when it cannot know in advance how many high risk referrals will arrive?
- What evidence would convince you that a nurse led pathway is safe for a group of patients before it is extended?
Case Study 4
Uneven outcomes after malnutrition screening across four wards
Alder Fenwick Health System, a network of two hospitals with 780 beds and a shared quality office
The situation
Across the network's four adult wards, the proportion of patients who received a documented nutrition review within two days of a positive screen varied widely from month to month. Ward C often showed near complete compliance, while Ward D frequently fell below half. Outcome indicators, including length of stay and readmissions within a set window, also differed in ways that did not match ward case mix. Prisca, the quality lead, was asked to find out whether the differences reflected real practice or the way the data were recorded. She had six weeks to report back before the next governance meeting.
The challenge
The data pointed to at least three explanations. Screening might be recorded on paper and entered late, which would make compliance look worse on some wards. Ward D's patients might be more complex, so the same outcome would be harder to achieve. Or the review itself might happen but be documented in a free text field that the indicator did not search. Each explanation predicted a different pattern in the records, and the team had only a few weeks to test them.
Analysis
Patient need is the reason the indicator exists, so the review has to begin with what the patient experienced rather than with the chart. A positive screen signals that someone may be losing weight or eating less than they need, and the evidence the team wants is the timing and content of the nutrition review that followed. Longer waits on the two weakest wards fit a real care gap and also fit late documentation. Clinical evidence alone could not separate the two, so the team pulled a small set of records and compared the screen date, the review date, and the date the note was written.
The screening protocol assigned the screen to nursing staff, the review to the dietitian, and the documentation standard to the ward manager, which is a sensible split on paper. In practice, the dietitians covered two wards each and worked from a different roster on Ward D, so reviews were often completed on the day after the referral was entered. The indicator counted the referral date as the start of the clock, which made any slow entry look like a missed review. Blaming the weakest ward would miss a process gap. The protocol needs a defined start point and an owner for the entry step.
- 1Fix the start pointRecord the screen completion time as a discrete field on every ward.
- 2Re-extract and compareCheck recorded dates against clinical notes in a sample from each ward.
- 3Assign shared review listsRemove dependence on one roster by pooling weekly review work.
- 4Chart monthly and decidePlot timely reviews by ward and escalate sustained gaps to the quality group.
Actions taken
- Agree a single start point for the nutrition review clock, defined as the time the positive screen is completed, and record it as a discrete field rather than free text.
- Re-extract the indicator from a sample of charts on each ward, comparing the recorded dates with the dates in the notes, before any ward is judged on the current number.
- Name a single owner for entering screening results, and give Ward D's dietitians a shared weekly review list so that reviews are not tied to one roster.
- Run a monitored cycle over three months, with a monthly run chart of timely reviews by ward, and bring any ward that stays below target to the quality group with its raw records.
Results
The re-extraction showed that about a third of the apparent gap on Ward D came from entry delays, not missed reviews. Once the start point was fixed as a discrete field, the network's timely review rate became more comparable across wards, and Ward D's rate rose over the first two months of the cycle. The run chart still showed a real gap on one ward, which led to a roster change. Prisca reported the findings with the raw sample attached, and the governance group accepted that the three month cycle would continue before any ward was formally rated.
Questions for discussion
- If the start point for the review clock had been fixed from the outset, which of the three explanations would the team have been able to test first?
- What would you need to see in a run chart before concluding that a ward's practice had changed rather than its recording?
- How should a quality group balance a ward's raw numbers against the complexity of its patients when deciding whether to intervene?
Case Study 5
A family disagreement over a long term nutrition plan
Westbrook Gardens Care Group, a 96 bed rehabilitation and continuing care hospital with a home support team
The situation
Ottoline, an 81 year old woman with advancing memory difficulties, was in a continuing care bed after a hospital stay that had left her weight low and her appetite unpredictable. Her daughter, Ruth, held a formal decision making role recorded in the file, and she asked the team to continue a nutrition plan that Ottoline had earlier told the team she did not want. Samir, the dietitian, had recorded Ottoline's own words about her wishes. The attending physician asked for a family meeting, and Beatriz, the social worker, asked the team to clarify exactly which decisions belonged to Ruth and which still belonged to Ottoline.
The challenge
The team had to hold two duties at once. Ottoline's expressed view was still evidence of her preferences, even if she could not reliably hold a decision over time, and Ruth's role carried authority that was real but bounded by what Ottoline would have wanted. Confidentiality also mattered, because the family meeting included relatives who had not been named as decision makers. The escalation route for unresolved disagreement was an ethics consultation, but nobody had yet agreed whether the situation met its threshold.
Analysis
Ottoline's needs are the starting point, even though she was not the person signing the consent. Her weight history, her recent intake and her responses at meals are clinical evidence, and they are also evidence of what she values. The dietitian's notes recorded that Ottoline became distressed when the discussion turned to feeding plans but was calmer when staff described her favorite foods. That detail does not settle the decision, but it changes the question from which plan is medically preferable to which plan fits what she has shown she wants. A sound approach keeps the clinical facts in view while giving her expressed preferences weight in the discussion.
The duties are shared across roles, and the difficulty is that each role saw a different part of the decision. The dietitian held the nutritional record, the physician held the medical assessment, the social worker understood the family, and the nurses saw Ottoline at meals every day. Local policy required the team to record decision making capacity for each decision separately, and to escalate to the ethics consultation when the family and the team disagreed about a significant treatment. Before the family meeting, the team should have written one statement naming the decision, the person who holds authority for it, and what Ottoline has said.
- Day oneDietitian records Ottoline's own words about her preferences.
- Day twoPhysician requests a family meeting and the roles are unclear.
- Day fiveFamily meeting held with Ruth, the social worker and physician.
- Day sevenEthics consultation reviews the file and defers the decision.
- Each meal reviewNamed staff revisit Ottoline's preferences with her directly.
Actions taken
- Hold a family meeting structured around the specific decision, with the attending physician, dietitian and social worker present, and with Ottoline included to the extent she can take part.
- Record separately what Ottoline has said about her wishes, who holds the formal role, and where the two differ, so that the file shows the reasoning rather than only the conclusion.
- Refer the unresolved disagreement to the ethics consultation now, and limit the information shared at the meeting to people with a defined decision role.
- Agree a review date for the plan, and a named person to revisit Ottoline's preferences with her directly at each meal review, so that her view is updated rather than assumed.
Results
The family meeting took place in the second week after the referral. Ruth attended with the social worker and the attending physician, and Ottoline joined for the first part, where she was able to say which foods she still enjoyed. The ethics consultation reviewed the file and agreed that the decision should be deferred for a set period while Ottoline's preferences were revisited at each meal review. The record now distinguishes her stated wishes from Ruth's formal role, and the team has a dated review point for the next decision.
Questions for discussion
- At what point in this case did Ruth's formal role stop being the only consideration, and what evidence would have marked that point?
- How should a team record a patient's expressed wishes when the patient can no longer hold a decision over time?
- What would a fair threshold for ethics consultation look like when family and clinicians disagree about nutrition support?
