I had to ask her to repeat that. Not because I didn’t hear her. I heard her fine. I just needed a second to catch up to what those words actually meant. I almost went into a surgery where they had the wrong blood type on file.

Two days from now, I could have been on that table and nobody would have known until it was too late. And the only reason we’re even having this conversation is because this particular surgeon was thorough enough to read the whole file before she picked up a scalpel.

I don’t know why I remember this next part so clearly, but I asked her how something like this happens. She said records transfers in the eighties were mostly done by hand or on early systems that matched patients by name, date of birth, and hospital. If two patients shared enough of those fields, the records could get cross-referenced and over time the data bled together. She said it’s rare but not unheard of. I don’t know if that made me feel better or worse. Probably worse, honestly, because it means this could have happened to anyone and most people would never find out.

Then I asked for the other woman’s name.

She couldn’t give it to me. Patient privacy, which I understood even if I hated it in that moment. But she said, ‘We’ve contacted her. She has the same problem.’ She told me the other woman’s file shows a knee surgery she never had. My knee surgery. We’ve basically been living inside each other’s medical histories without knowing it. Every doctor who looked at my chart and saw that hysterectomy, and didn’t say anything, probably just assumed I’d had it done before I started seeing them. And I never thought to question it because I didn’t know it was there.

I actually almost cried on the phone. Not from relief, which is what you’d expect. More from just the sheer strangeness of it. Forty years. Every physical, every blood draw, every time someone asked about prior surgeries and I said no and they were looking at a chart that said yes. Did any of them think I was confused? Did they think I just forgot I’d had a hysterectomy? I keep going back over old appointments in my head trying to remember if a doctor ever looked at me a little funny, and I honestly can’t tell anymore if I’m remembering real things or just filling in gaps.

The surgeon said she’d have to reschedule the surgery until both files could be formally separated and verified. That process, she said, could take several weeks. I said that was fine. I would have said anything was fine at that point. I was still sitting at that kitchen table. My coffee was completely cold. I hadn’t moved in twenty minutes.

Before she let me go, she said, ‘The other woman asked me to tell you something.’

I wasn’t expecting that. I said okay.
