Shortened Treatments, a Job, and a Request for Secrecy
Mr. T is 39 and has been on in-center hemodialysis for 8 months. Over the past 6 weeks he has shortened 6 of 18 sessions to an average of 3 hours 10 minutes and missed two. Predialysis potassium has ranged 5.9–6.8 mmol/L and phosphate 8.1 mg/dL. He works as a warehouse shift supervisor, says he cannot lose the job, and describes dialysis as "the machine being the boss of me." He has stopped attending the dietitian and now asks you not to tell the nephrologist about the shortened sessions.
1. What are your priorities, and how do you handle the request to keep the shortened sessions from the nephrologist?

Safety first. Potassium of 6.8 mmol/L in a patient receiving shortened dialysis is a risk of serious arrhythmia. Assess for symptoms and obtain a 12-lead ECG if potassium is at or above 6.5 or symptoms are present; review medications (RAAS inhibitors, potassium binders, missed doses), recent dietary intake, and access function. Shortened sessions also mean chronic underdialysis and fluid overload, which drive the phosphate and potassium values.
The request for secrecy cannot be granted. Explain plainly and without shaming: the shortened sessions are directly relevant to his safety, the team cannot treat him safely with incomplete information, and everything relevant is documented and shared with the nephrologist and the interdisciplinary team. What you can offer is to support him in raising it himself first, so he is not ambushed, and to be present when he does.
Do not moralize. Adherence is a symptom, not a personality flaw. Explore the real constraint: shift patterns, travel time, fear of losing income, fatigue, depression. A nurse who immediately lectures loses access to the actual problem.
2. The team is considering a disciplinary conversation. Propose a better approach and the specific options you would raise.

Use motivational interviewing rather than confrontation. Open question: "What makes the shorter sessions necessary for you right now?" Reflective listening, affirmations of his commitment to work and family, and a summary that names the tension without resolving it for him: "You want to keep this job and you also don't want to end up in the emergency department with a potassium of 7." Explore his confidence and importance ratings for change. This is more likely to produce a workable plan than a warning about consequences.
Screen for depression with PHQ-2/PHQ-9 and ask about sleep, appetite, energy, and hopelessness-depression is common in dialysis and masquerades as noncompliance. Involve the social worker.
Concrete options to place on the table:
- Reschedule to an evening or later shift that accommodates his work schedule.
- Home hemodialysis or nocturnal home hemodialysis, which restores control of his time.
- Peritoneal dialysis, if he is a candidate and prefers it.
- Referral for kidney transplant evaluation.
- A letter supporting a reasonable workplace accommodation (e.g., a fixed shift) and information on FMLA.
- A renegotiated, honest target: if 4 hours three times weekly is genuinely impossible, negotiate a documented plan (e.g., four shorter sessions) with the nephrologist rather than silent cuts.
Frame it as redesigning the treatment to fit his life, not as a reward for compliance.
3. What education would you deliver now, and how would you deliver it so it actually lands?

Deliver it through teach-back, in short chunks, tied to what he cares about. Start with his own goal-keeping the job-then connect the physiology to it: shortened sessions mean potassium and fluid are not cleared, and the consequence is not a lecture but an emergency department visit or an arrhythmia that costs him far more workdays.
Teach-back script: "If I said your potassium is at the level where the heart rhythm can become dangerous, what would you tell your partner about why we're asking you to stay for the full session?" Correct misunderstandings, re-ask in a different way.
Behavioral, specific goals rather than "watch your potassium": identify his actual high-potassium foods (salt substitutes, potatoes, tomatoes, oranges, dried fruit) and agree on two swaps; discuss binders taken with food and timing around his shift.
Re-engage the dietitian in a different format-a brief phone or video visit, or a session coordinated with his work schedule. He declined the previous format, not necessarily the content.
Address the emotional load. Screen for depression, ask about sleep and sexual function (often unspoken drivers of distress), and acknowledge grief about his health.
Document what was taught, his response, and his stated goals-this protects him and the team.
