Spanish for dialysis nurses: the patient on a tunneled catheter who refuses AV fistula surgery because he watched his cousin bleed at a backyard barbecue, the conversation that cannot begin with statistics, and the social worker referral that is not a referral away

Armando Castillo is 58 years old. He has been on hemodialysis for three years, Monday, Wednesday, Friday, through a tunneled dialysis catheter in his right chest. He has had two catheter infections in three years. The vascular surgeon completed the AVF mapping in March. The nephrologist told Armando at his last clinic visit that his veins look good, that he is an excellent candidate, and that they would like to schedule the fistula surgery before summer. On a Monday in May, the dialysis nurse sits down to walk through the access conversation the access coordinator flagged. She gets as far as the word “fístula” before Armando says, without raising his voice, without looking angry: “No. No quiero la cirugía.”

What the nurse does not know yet

Armando was born in Jalisco and came to the United States in 1993. He worked construction in the Inland Empire for twenty-two years before his diabetes and hypertension took his kidneys. He is careful. He takes his medications. He shows up. He has missed four sessions in three years, twice for illness and twice for transport failures he called the clinic about in advance.

His cousin Rodrigo lives in Montebello. Rodrigo has been on dialysis for eleven years. He has had a functioning AV fistula in his left forearm for most of that time.

In July 2019, Rodrigo was at a family barbecue in the backyard of his daughter’s house in Montebello. It was a Sunday afternoon. There were forty people. Rodrigo’s fistula ruptured at a pseudoaneurysm that had been present for several months and that the dialysis unit had documented and been watching. The bleeding was dramatic and fast. Rodrigo’s daughter called 911. The ambulance arrived in eight minutes. Rodrigo survived. He received care at the hospital, the pseudoaneurysm was surgically corrected, the fistula was revised, and he is still on dialysis today.

Armando was at the barbecue. He was standing seven feet away when it happened. He was the one who pressed his shirt against Rodrigo’s arm while someone else called 911. He held pressure for eight minutes while his cousin looked at him and said “no me dejes” (don’t leave me).

Three years later, Armando started dialysis. Rodrigo called him and said: “Hermano, cuídate. La fístula da miedo pero el catéter me mató dos veces de infección. La fístula vale la pena.”

Armando heard what Rodrigo said. He also did not hear it in the way Rodrigo meant it. The image of the barbecue is older and louder than the phone call.

None of this is in the chart. The chart says: access type: TDC (tunneled dialysis catheter); two prior catheter-related infections; AVF mapping completed March 2026; patient verbally declined surgical referral.

Failure mode 1: The statistical argument that answers the wrong question

The nurse who hears “no quiero la cirugía” and reaches for the outcomes data is not wrong about the data. Arteriovenous fistulas have better long-term patency than tunneled catheters. They are associated with lower rates of catheter-related bloodstream infections, lower hospitalization rates, lower mortality. The Fistula First Breakthrough Initiative documented all of this. KDOQI guidelines recommend AVF as the preferred access for most hemodialysis patients. The nephrologist is correct that Armando is a good candidate.

None of that is what Armando is refusing.

A patient who says no to a surgical recommendation after three years on dialysis has been living with this disease long enough to have a position. He is not refusing because he forgot that the nurses prefer fistulas. He is refusing because of something specific, and the specific thing is not addressed by the mortality table.

The conversation that proceeds like this:

“Señor Castillo, entiendo que no quiere la cirugía, pero quiero que sepa que el catéter tiene más riesgo de infección que la fístula. La fístula es el acceso más seguro a largo plazo. Su nefrólogo lo recomienda por una razón.”

— is answering a question that Armando has not asked. He did not say no because he was unaware that fistulas are clinically preferred. He said no because when the nurse said “fístula,” what he heard was not a surgical procedure but a July afternoon in Montebello and his cousin’s face and the word “no me dejes.”

The conversation that opens correctly:

“Señor Castillo — cuando dijo que no quiere la cirugía, yo lo escuché. Antes de decirle cualquier cosa sobre la fístula, quiero entender. ¿Me puede contar qué fue lo que le hizo decir que no?”

(Mr. Castillo — when you said you don’t want the surgery, I heard you. Before I say anything about the fistula, I want to understand. Can you tell me what made you say no?)

Then she stops. She does not fill the silence. She does not soften the question by offering possible answers.

Armando will tell her about Rodrigo if she waits. He may not tell her on the first try. He may say “simplemente no quiero” (I just don’t want to) and she will need to sit with that for a moment before asking again:

“¿Hay algo específico que le preocupa de la cirugía? ¿Algún miedo, algo que haya visto o escuchado?”

(Is there something specific that worries you about the surgery? A fear, something you have seen or heard?)

The second question gives him language for what he is carrying. Most patients who have seen a fistula complication do not know that what they are experiencing is a normal trauma response that can be named and addressed. They experience the refusal as self-evident, a fact that requires no explanation, because the image is so vivid that the gap between the image and the clinical recommendation seems obvious to them even when it is invisible to the nurse.

Failure mode 2: The clinical risk differential that has to be honest about both sides

Once the nurse knows about Rodrigo, she faces two tempting errors.

The first error is minimization.

“Eso es muy raro, señor Castillo. Las fístulas son muy seguras. Lo que le pasó a su primo no es lo normal.”

Everything in those sentences is clinically true. Pseudoaneurysm rupture is rare. Fistulas are, in aggregate, the safer access. What Rodrigo experienced is not the typical course.

But Armando pressed his shirt against his cousin’s arm for eight minutes. He knows it was real. He knows it can happen. The nurse who minimizes it has just told him, in the most diplomatic possible terms, that what he saw does not count in the clinical calculus. He will hear it as: you are being irrational, and the correct rational response is to agree with the nephrologist.

The second error is skipping Rodrigo entirely and pivoting directly to catheter risks.

“Entiendo que tiene preocupaciones. Pero le quiero hablar del riesgo del catéter. El catéter tiene más probabilidad de infección…”

This maneuver acknowledges the emotion and immediately moves past it. The patient experiences it as: the nurse heard me say something important and responded by changing the subject. The information about catheter risks that follows this maneuver will not land because the patient is still in the moment before the pivot.

What belongs in the conversation: both sides named honestly, in the right order.

First, Rodrigo:

“Lo que le pasó a su primo es real. Yo no le voy a decir que eso no puede pasar. Una fístula que lleva mucho tiempo — como la de su primo, once años — puede desarrollar lo que llamamos un pseudoaneurisma, un ‘globito’ que se forma donde se ha pinchado muchas veces. Si ese ‘globito’ crece y no se vigila, puede romperse. Eso es lo que usted vio. Es una complicación real. Y también es una complicación rara — la mayoría de personas con fístula nunca tienen ese problema. Y su primo sobrevivió, y sigue en diálisis hoy.”

(What happened to your cousin is real. I am not going to tell you that cannot happen. A fistula that has been in place for a long time — like your cousin’s, eleven years — can develop what we call a pseudoaneurysm, a “little bubble” that forms where it has been needled many times. If that “bubble” grows and is not monitored, it can rupture. That is what you saw. It is a real complication. And it is also a rare complication — most people with a fistula never have that problem. And your cousin survived and is still on dialysis today.)

A pause. Not a pivot. A pause that allows Armando to confirm that he was heard correctly.

Then the distinction between a rupture and the surgery:

“Y hay algo importante que quiero que sepa. La cirugía para crear la fístula y la ruptura que su primo tuvo son dos cosas distintas. La cirugía es planeada — un cirujano conecta una vena con una arteria en el brazo, bajo anestesia, en un quirófano, en treinta a noventa minutos. La vena que se crea después tiene que madurar seis u ocho semanas antes de que la usemos para la diálisis. La ruptura que su primo tuvo pasó con una fístula que ya tenía once años y un ‘globito’ que se estaba vigilando. No es lo mismo que la cirugía para crearla. Y hay cosas específicas que nosotros revisamos en cada sesión para detectar eso temprano.”

(And there is something important I want you to know. The surgery to create the fistula and the rupture your cousin had are two different things. The surgery is planned — a surgeon connects a vein to an artery in the arm, under anesthesia, in an operating room, in thirty to ninety minutes. The vein that is created then has to mature six to eight weeks before we use it for dialysis. The rupture your cousin had happened with a fistula that already had eleven years and a “bubble” that was being monitored. It is not the same as the surgery to create it. And there are specific things that we check at every session to detect that early.)

Then — and only then — the catheter risk:

“Ahora quiero hablarle del catéter. Usted lleva tres años con él. Ha tenido dos infecciones. Cada infección de catéter en alguien que hace diálisis puede convertirse en una infección en la sangre — en inglés lo llaman bacteremia o sepsis. Eso no es como una infección de la piel. Es una infección que entra a la sangre directamente y puede llegar al corazón o a los pulmones. Hay personas que terminan hospitalizadas semanas por eso. La segunda infección que usted tuvo fue más complicada que la primera. Si hubiera una tercera, la probabilidad de que sea aún más complicada es alta. No le digo esto para asustarlo. Se lo digo porque usted merece saber los dos lados de la decisión que está tomando.”

(Now I want to talk about the catheter. You have had it for three years. You have had two infections. Every catheter infection in someone who does dialysis can turn into an infection in the blood — in English they call it bacteremia or sepsis. That is not like a skin infection. It is an infection that enters the blood directly and can reach the heart or lungs. There are people who end up hospitalized for weeks because of that. The second infection you had was more complicated than the first. If there were a third, the probability of it being even more complicated is high. I am not telling you this to frighten you. I am telling you because you deserve to know both sides of the decision you are making.)

The sequence matters. Rodrigo first. The distinction between rupture and surgery second. Catheter risk third. Not because the catheter risk is less important — it is, in the aggregate, the more urgent risk — but because a patient who has not been heard about what he is afraid of cannot hear the clinical information that comes after. The risk differential is not a debate. It is a map. Armando needs the map. He does not need to be won.

Failure mode 3: The questions the surgical consent never asked

The refusal may not be entirely about Rodrigo.

There may be other things behind “no quiero la cirugía” that the nursing conversation does not reach because the nursing conversation has been about the fistula and the catheter and has not asked about anything else.

There may be a prior negative surgery experience. A hernia repair in 2014 that had complications. An anesthesia reaction that was not explained. A recovery that was more painful or more prolonged than what he was told to expect. The question:

“¿Ha tenido alguna cirugía antes — algo que no salió como esperaba, o que le dejó con alguna preocupación sobre las cirugías en general?”

(Have you had any surgery before — something that did not go as expected, or that left you with some concern about surgeries in general?)

There may be a belief about what a permanent fistula means about the permanence of his condition. Armando has been on dialysis for three years. He may still be carrying the belief, or the hope, that this is temporary. That a transplant could come. That his kidneys could recover. That dialysis is something happening to him for now, not a permanent architecture of his life. A fistula, visible in his arm, permanent, buzzing under his skin when he runs his fingers over it, may be what makes it permanent in a way the catheter under his clothes does not.

The question — carefully:

“A veces los pacientes me dicen que la fístula les parece diferente al catéter en una forma que no es sólo médica. Que se ve, que siempre está ahí. ¿Hay algo de eso en lo que usted siente?”

(Sometimes patients tell me that the fistula seems different from the catheter in a way that is not only medical. That it is visible, that it is always there. Is there something of that in what you feel?)

This question does not need an answer immediately. It needs to be in the air. Armando may nod. He may say nothing. He may come back to it next session.

There may be questions about the surgical consent process that were never answered in language Armando could act on. The consent form was in English. The nephrologist’s explanation was in the English of a man who gives surgical recommendations twenty times a week and for whom “arteriovenous fistula” is a phrase without edges. The questions Armando had in that room may not have been the questions he could ask.

The question:

“Cuando el doctor le explicó la cirugía, ¿le quedaron preguntas que no hizo? ¿Hubo algo que no entendió bien, o algo que quería saber pero no sabía cómo preguntarlo?”

(When the doctor explained the surgery, were there questions you did not ask? Was there something you did not fully understand, or something you wanted to know but did not know how to ask?)

These questions are the reason the social worker referral is not a hand-off.

The social worker can spend forty-five minutes with Armando in a room without a machine beeping and a chair to complete. She can ask the prior surgery question and have time to follow it. She can explore the permanence belief without the access coordinator waiting for a decision. She can contact the transplant social worker to give Armando an honest picture of where he is on the list and what the realistic timeline looks like, so that the fistula decision is not made against a horizon of hope that has not been calibrated recently.

The referral:

“Quiero pedirle que hable con nuestra trabajadora social. No porque usted esté equivocado en dudar — sus preguntas son perfectamente razonables, y la decisión es suya. Es porque hay cosas en lo que me contó sobre su primo, y en lo que me parece que está pensando, que merecen más tiempo y más conversación de la que yo le puedo dar en el turno de hoy. Ella no está aquí para convencerlo de nada. Está aquí para asegurarse de que cuando usted tome su decisión, tenga toda la información y todo el apoyo que necesita para tomarla bien. Y la decisión no tiene que ser esta semana. Lo que sí necesitamos hacer esta semana es asegurarnos de que usted entiende lo que está pasando con el catéter — porque eso no puede esperar indefinidamente.”

(I want to ask you to speak with our social worker. Not because you are wrong to hesitate — your questions are perfectly reasonable, and the decision is yours. It is because there are things in what you told me about your cousin, and in what I sense you are thinking about, that deserve more time and more conversation than I can give you in today’s shift. She is not here to convince you of anything. She is here to make sure that when you make your decision, you have all the information and all the support you need to make it well. And the decision does not have to be this week. What we do need to do this week is make sure you understand what is happening with the catheter — because that cannot wait indefinitely.)

The last sentence is important. The fistula decision can wait a week. The catheter risk cannot wait indefinitely. These are two separate clocks, and the nurse names both of them so Armando understands that the deferral is of the surgical decision, not of his care.

La decisión de Armando

Three weeks after the first conversation, Armando agrees to speak with the vascular surgeon for a second consultation. Not to schedule the surgery. To ask questions in Spanish with the social worker present.

He asks: What happens if the bubble forms in mine, like with my cousin? How will I know? What do I do?

The surgeon answers in plain terms: the nursing team inspects the fistula at every session; there are specific things Armando himself can feel for — a pulsing lump that was not there before, or a part of the arm that is growing; those are the call-us-immediately signs. Not as emergencies to discover at a barbecue but as clinical observations to report at the next session, or to call about the same day.

He asks: My cousin said the catheter gave him two sepsis episodes. Was that the catheter?

The surgeon says yes. That is what the catheter does over years, in an immunocompromised patient who is on dialysis three days a week. The catheter is a portal into the bloodstream that does not close between sessions.

Armando schedules the surgery for July.

He tells the nurse before she asks: “No me convenció la estadística. Me convenció que me preguntaron sobre Rodrigo.”

(It wasn’t the statistics that convinced me. It was that they asked about Rodrigo.)

The nurse who asked about Rodrigo was the nurse who had the conversation that could actually go somewhere. The nurse who would have started with the outcomes table would have documented: patient verbally declined, education provided, will follow up. And Armando would be in the chair again on Monday with the catheter, and the catheter infections that are the slower version of the same risk he is trying to avoid.

What the three failure modes have in common

The statistical argument, the minimization of Rodrigo, and the failure to ask the questions the consent never asked: they are all versions of the same error.

They assume that the refusal is a knowledge gap that can be filled with information.

Armando does not have a knowledge gap. He has a lived experience that is more vivid than any table and more credible, to his nervous system, than any clinician’s explanation. The information he needs is not more or different information about fistula outcomes. The information he needs is: what specifically happened to Rodrigo, and how specifically is that different from what will happen in this surgery, and what specifically will happen if what happened to Rodrigo starts to happen to him, and who specifically will be watching.

Those are answerable questions. They are not on the mortality table.

The nurse who asks “cuénteme” before she explains anything is the nurse who finds out which questions to answer.
