Nephrology and Dialysis Care Case Studies
Healthcare5 Case StudiesUpdated Sep 2026
These five case studies come from the working life of kidney care teams, where a patient may attend a dialysis chair three times a week and still present with a problem that needs a decision within the hour. Each case is built from composite details drawn from fictional units. Each asks you to weigh the patient's needs, the evidence in front of the team, the coordination across shifts and services, and the protocols that define what comes next. Treat them as sequences of judgment, not lists of right answers. The discussion questions are there to test your reasoning.
Case Study 1
A rising weight gain and a delayed call
Ashgrove Regional Renal Unit, a hospital dialysis unit with 22 chairs and an on call nephrology rota
The situation
Tomas, a man in his late sixties, has attended the unit for three sessions a week for four years. In the second week of a routine run, the bedside nurse, Ruth, records an interdialytic weight gain larger than his recent average and notes that he has been waking breathless. His ankles are swollen compared with the previous visit. He puts the breathlessness down to a cold. The previous week's blood results are filed in the chart but no doctor has reviewed them. The unit's escalation protocol lists these features as a reason to contact the on call nephrologist the same day, but the evening session is already running with two nurses covering six chairs.
The challenge
The team must decide how much weight to give a set of features that each look minor alone. Ruth is not sure whether the weight gain reflects fluid, diet, or a scale error. The consultant is reachable by phone but has three ward reviews pending. The question is whether to hold the session, call the consultant now, arrange a same day clinic review, or wait for the next scheduled round. Each option carries a different risk of delay, and the protocol does not rank them for this combination.
Analysis
Teams grounded in Nephrology and Dialysis Care begin by separating what the patient needs from what the team is able to deliver in that moment. For Tomas, the need is timely review of a change in breathing and fluid status, which is a question of safety rather than comfort. The evidence is a cluster: a higher than usual weight gain, new waking breathlessness, swelling, and a week old blood panel that nobody has read. Together they point toward a patient who may be accumulating fluid, and the reading of the chart should be done by someone with the authority to act on it rather than left for the next scheduled round.
Coordination is the weak point here. Ruth can see the chart and the chairs, but the decision to hold a session or change the plan belongs to a physician, and the on call route is only useful if the call is made with the whole picture. A short structured handover to the consultant, covering the weight trend, the symptoms in Tomas's own words, the unreviewed results, and the staffing pressure, lets the physician decide quickly. The protocol also asks that the charge nurse be told when a patient is flagged this way, so the evening rota can change rather than the flag being absorbed into a busy session.
- 1Notice the changeWeight gain and new breathlessness recorded together at the bedside.
- 2Read the chartCheck the unreviewed blood results alongside the session notes.
- 3Call the consultantHand over trend, symptoms, and staffing pressure in one call.
- 4Adjust the sessionAssign a named observer and record the revised plan.
- 5Audit the flagReview monthly whether escalation happened and how quickly.
Actions taken
- Ruth calls the on call nephrologist using the handover sheet, reads out the weight trend, the symptoms, and the unreviewed results, and asks for a decision on the session before the chair is released.
- The charge nurse reassigns one chair and one nurse so that Tomas is observed with a named person for the remainder of the session, and records the rebalanced rota in the unit log.
- Before the shift ends the team writes an entry linking the weight trend, the symptoms and the consultant's decision, so the next nurse sees why the plan changed.
- At the next monthly quality meeting, the unit reviews every flagged weight gain from the preceding month to check whether escalation happened and how long it took.
Results
The consultant reviewed the handover promptly and arranged for Tomas to be seen in the unit clinic before he left, after which his plan was changed and recorded in the chart. Ruth's note gave the physician what was needed in one pass, and the evening rota was adjusted without a second call. At the monthly review, the unit found that four of six flagged weight gains had been escalated, while two had waited more than a shift for a doctor to read the chart. The team moved the flag to the top of the handover sheet.
Questions for discussion
- Which feature in this case would you weight most heavily, and how would the protocol help a nurse who sees it alone during a busy session?
- What should a handover to the consultant contain so that the physician can decide without calling back for missing facts?
- How would you tell whether the monthly review is measuring escalation or simply measuring how often the flag was used?
Case Study 2
A missed session lost between two handovers
Harrowmere Kidney Services, a regional service linking a dialysis unit with two inpatient wards
The situation
Mariam, a woman in her seventies, was admitted to a medical ward from the dialysis unit after a fall at home. She has sessions on Monday, Wednesday and Friday. The admitting nurse received a verbal handover from the dialysis charge nurse, Dev, late on a busy afternoon. The written transfer summary listed her diagnoses and her allergies but did not state that her next session was due the following morning, nor that a planned review of her access site had been requested for the same week. The ward's evening team read the summary as complete. The gap was not noticed until the morning, when the ward nurse asked the dialysis unit about the missing session.
The challenge
The verbal handover was accurate, and the written summary was complete in its own terms. The problem sat between the two. Neither clinician owned the question of whether an upcoming session and a pending access review belonged on the transfer. The dialysis unit assumed the ward would ask. The ward assumed the summary covered anything time critical. The team must decide how to close the gap without turning every transfer into a long meeting and whether the risk to Mariam requires action before the next routine handover.
Analysis
Mariam's needs are continuity and safety. She depends on scheduled sessions to manage fluid and waste, and a missed session is not a neutral event but a change in her state that the next team must anticipate. The evidence on the ward included her diagnoses and the fall that brought her in, but not the timing of her next session or the pending access review, both of which are time bound. A transfer summary is only as good as the questions it forces the sender to answer. The summary answered what the sender thought was central and left out what the receiver needed within the next twelve hours.
Transfer protocols in most units rely on a structured summary, a verbal handover, and a named person accountable for pending items. The protocol problem here is less about missing paperwork than about ownership. Pending time bound events such as a session or a review should sit on a short list that the sending nurse reads aloud and the receiving nurse signs back. Without that read back, the verbal account and the written summary each assume the other covers the gap. Good practice asks the sending unit to name who will check on the next session, because a dialysis unit's obligation does not end at the ward door.
- Late afternoonVerbal handover given while the dialysis unit is busy.
- Evening transferWritten summary accepted as complete by the ward team.
- OvernightNo one checks the next session or the pending review.
- Early next morningWard nurse calls the unit and finds the missed session.
- Same daySession arranged and the event logged as a near miss.
Actions taken
- Build a transfer checklist with a fixed line for the next dialysis session, the time of any pending access review, and the name of the person who will confirm each item was received.
- Require a read back of pending time bound items at every transfer between the dialysis unit and a ward, and have both nurses initial the entry.
- Give every admitted dialysis patient a unit contact with a direct number on the transfer summary, and have that contact confirm the next session in writing to the ward.
- Review every transfer that involved a missed or delayed session in the monthly quality meeting, tracking how the gap was found, how long it lasted, and whether the checklist was used.
Results
The ward nurse rang the dialysis unit early, and the session was arranged for later that day. The access review was rebooked for the next week. Mariam was not harmed by the gap, but the event was logged as a near miss because two accounts of the same transfer had both been accepted. In the first month of using the checklist, the unit completed it for 19 of 21 transfers, and read back was recorded in 17 of those. Dev, the dialysis charge nurse, said the named contact mattered most, because the ward had a person to call.
Questions for discussion
- Which single element of the transfer summary, if it had been required, would have closed the gap, and what would it have cost the sending nurse to complete it?
- Who in your service currently owns pending time bound items during a transfer, and would the admitting team name the same person without being asked?
- How would you tell a checklist that people complete from one that they actually use, and which data would you collect to make that distinction?
Case Study 3
Urgent referrals and a short staffing week
Corvane Valley Dialysis Network, three satellite units and one main site with 38 chairs
The situation
The network runs 38 chairs across four sites and currently treats 214 patients on a maintenance schedule. In the third week of the quarter, two nurse vacancies coincided with planned maintenance that takes one machine at the main site out of use for a day. At the same time, the hospital referred three patients whose kidney function had dropped suddenly and who need sessions within a short window. The scheduling coordinator, Ines, could move nine stable patients from the main site to satellite evening slots, but the satellite has no evening nurse this month. The charge nurse at the main site, Oscar, says his team can absorb one extra session but not two.
The challenge
The network cannot add chairs this week, so the choice is about order, timing, and who carries the cost of waiting. Three urgent referrals cannot wait for the usual rota. The stable patients who might move would lose their usual chair time and transport arrangements, which for some means a longer day. Every option pushes a risk somewhere, and the network's own policy asks that no patient be moved without a clinician agreeing that the change is safe for them.
Analysis
The three urgent referrals have the strongest claim on capacity, because the evidence is a recent fall in kidney function and a clinician's judgment that they cannot safely wait for the usual schedule. Triage in this setting should rest on clinical criteria written down in advance, not on who called most recently or who is easiest to move. The stable patients are not a lower priority in any moral sense, but their needs are about continuity: predictable transport, familiar staff, and a chair time that fits work or caring responsibilities. Moving them carries a real cost that should be counted, not treated as free.
Each lever has a different owner. Triage sits with the clinical lead, who must approve any change in the order of urgent and routine patients. Scheduling belongs to Ines, but she cannot fill satellite evening slots without a nurse rostered there. Resource decisions, including the timing of the planned maintenance, belong to the estates team and the network manager. A plan that looks sound on paper can fail if these owners hear about the change on the same afternoon. The network protocol asks for a joint call once demand passes two thirds of planned capacity, and that call should happen before any patient is told their slot is changing.
Actions taken
- Write down clinical criteria for the three urgent referrals and have the clinical lead sign them before any reordering, so that the decision rests on documented need rather than on who called first.
- Ask the estates team whether the planned maintenance can be split so that the main site keeps one machine running on the most constrained day, and record the answer before the schedule is published.
- Offer stable patients a choice of alternative slots with the same transport, and confirm in writing that a clinician agreed each move so no one loses a chair without knowing why.
- Hold a short joint call with the clinical lead, scheduler, charge nurse and estates contact each morning for the rest of the week, and log every change to capacity and every patient moved.
Results
The three urgent referrals were placed in the first available chairs and were seen within the window requested. Of the nine stable patients, six accepted alternative slots, two kept their original times after discussion, and one was moved, with written agreement, because a transport problem left no other workable option. The estates team split the planned maintenance so that the main site kept one machine running on the most constrained day. Each morning call was logged, and by the end of the week no patient had been moved without documented clinical agreement.
Questions for discussion
- When two legitimate priorities compete for the same chair, what evidence should decide the order, and who should be able to override a written criterion?
- How would the network know whether a stable patient's move caused harm that appeared only weeks later, and what would it need to record now to find out?
- Which of the three levers, triage, scheduling, or resource allocation, is most often used first in your own service, and does that habit serve the patients who are hardest to move?
Case Study 4
Inconsistent indicators across six dialysis units
Brackenridge Kidney Network, a quality office serving six dialysis units
The situation
Brackenridge Kidney Network runs six dialysis units and reports a short set of indicators each month, anonymized before they reach the quality office. Across the last two quarters, the figures for unplanned admissions and late starts varied widely between units, even where patient mix looked similar. One unit reported an unplanned admission rate of 11 per 100 patients in the quarter, while the network average was 6. Another unit recorded the highest rate of documented monthly reviews of results but the lowest rate of patients with a current access plan. The quality lead, Marisol, has been asked whether the variation reflects real differences in care or the way the units count things.
The challenge
The indicators do not yet tell the team which differences matter. Counting rules may vary between units, since one unit records a late start from the scheduled time and another from the moment the patient reaches the chair. The team must decide whether to standardize the definitions first, which delays improvement by a cycle, or to act on the units with the largest gaps and accept that some of the gap may be measurement. Staff in the high admission unit are already anxious about being singled out.
Analysis
The patients behind these numbers need the same things anywhere: sessions that start and finish on time, early notice of a change in their condition, and an access plan that is reviewed before it becomes an emergency. The indicators are a proxy for those needs, and a proxy can mislead. A high admission rate may reflect a unit that refers more readily, a case mix with more frail patients, or a unit that tracks admissions more carefully. The evidence should be read as a set. Only when admissions, late starts, and access reviews move together does it begin to suggest a process problem rather than a counting one.
Protocols in this network are written for clinical care, but the indicator definitions sit in a separate document that charge nurses rarely open. Coordination therefore has to start with agreement on what each number means. A shared definition sheet, signed by the medical lead and nurse managers, should state when a late start is counted, what counts as a documented review, and how an admission is linked to a session. Without that, a unit that improves its recording may appear to get worse. The team should check that the network's escalation and access review protocols are being applied the same way across units before any unit is judged.
- Define Agree one written definition for each indicator across units.
- Test Run one process change in the two widest gap units.
- Measure Publish monthly figures with trial units marked clearly.
- Decide Judge the change against the rule agreed beforehand.
Actions taken
- Agree a single page definition sheet for the four indicators, signed by the medical lead and nurse managers, and send it to every unit before the next data pull.
- Recalculate the last two quarters under the agreed definitions and show each unit its own before and after figures so that recounting is visible rather than hidden.
- Trial one process change, a fixed weekly access review, in the two units with the widest gaps for six weeks, with a named nurse owning the weekly check.
- Publish the monthly indicators for all six units with the trial units marked, and review them at the quality meeting against a fixed rule for when a change is judged to have worked.
Results
After the definitions were agreed, the recount changed the picture. The unit with the highest admission rate moved toward the middle once late starts were counted consistently. The unit that had looked strongest on reviews fell back once its access plans were checked. The access review trial ran for six weeks in the two units with the widest gaps. In one of them, the share of patients with a current access plan rose from 58 to 81 percent, and the team agreed the rule for judging success before the trial ended.
Questions for discussion
- What would you expect to change in the indicators if a unit's recording improved but its care did not, and how would you design a check that separates the two?
- Which indicator in your own service is most vulnerable to counting differences, and who is responsible for writing down its definition?
- How long should a trial run before a team decides a change has worked, and what would make you extend it rather than adopt it?
Case Study 5
A daughter's calls during a dialysis decision
Keldrin Kidney Clinic, an outpatient nephrology clinic with a shared decision service for advanced disease
The situation
Waleed, a man in his seventies, has been under the clinic's care for several years for progressive kidney disease. The kidney team has recommended a discussion about whether to start dialysis or to pursue conservative management, which focuses on symptom control and planning. Waleed has capacity and has told the nurse specialist, Anika, that he wants time to think. His adult daughter, Layla, telephones the clinic twice in a week asking for his results and whether he has decided. She says she holds his health care power of attorney, but the file names her only for finances. Waleed has not asked her to be involved and has asked the clinic to keep his results to himself.
The challenge
The team owes Waleed a decision that is his own, which means he must hear the options without pressure and at a pace he sets. It also owes Layla a response that respects her concern without breaching confidentiality. The file on proxy authority does not give her a right to his information. The open question is whether Waleed would want Layla included in the discussion if he were asked directly, and whether the clinic can ask him without making him feel watched.
Analysis
Waleed's needs are both clinical and personal. The clinical picture gives the team a real decision to make, because starting dialysis and pursuing conservative management lead to different patterns of daily life, travel, and time in hospital. The evidence the team can offer him includes his current kidney function trend, his symptoms, his functional status, and what each path would involve in practice. Those facts should be presented in plain language, with a clear account of what can and cannot be known in advance. Waleed's values, his sense of what a good week looks like, are part of the evidence too, and they are only available from him.
Confidentiality and consent here are governed by the clinic's information policy and by the capacity assessment on record. Because Waleed has capacity, the clinic does not disclose his results to Layla without his agreement. The nurse specialist's first step is to ask Waleed privately, without pressure, whether he would like Layla to be involved and in what way, and to record his answer. If he agrees to limited sharing, the consent should be specific about what is shared. If Layla's calls continue, the practice manager should be informed so that a consistent script is used, and the medical lead should join if there is any sign that Waleed's decision is being influenced.
Actions taken
- Arrange a private conversation with Waleed, without Layla present, to ask how much he wants her involved and in what way, and record his answer in his own words.
- Give Layla a single, consistent reply that confirms the clinic received her call, explains that results can only be shared with the patient's agreement, and offers to pass on a message.
- Set out the two pathways in a written summary that Waleed can keep, covering what each would involve day to day, what remains uncertain, and when he can return to talk it through.
- Record the consent decision and its scope in the clinical file, and schedule a review with the medical lead within the next week so that the choice is checked against any change in his health.
Results
Waleed met the nurse specialist alone first, then asked for Layla to join a second meeting to review the written summary. He gave limited consent for the clinic to share a short written update with Layla, covering the timing of the next appointment but not his results. Layla's calls dropped to every two weeks once the reply was agreed. The clinic logged the consent and its scope, and the review with the medical lead was held within the agreed week, after which Waleed said he needed more time before deciding.
Questions for discussion
- At what point does a family member's persistence become a reason to change how the clinic communicates, and at what point does it become a confidentiality concern?
- If Waleed later loses capacity, how should the clinic treat the consent he gave earlier, and what should the record show about his wishes?
- How would you check that the written summary helped Waleed decide, without making the check feel like a test of his understanding?
