There's no medical reason for a doctor to be on-call 24/7/365, and it's stupid to expect them to. If an urgent medical issue comes up at 2 AM, the patient can go to the ER, which is what the doctor would tell them to do anyway.
My aunt had a condition that causes fluid build up in her brain. She has a slightly unusual shunt arrangement, and over Christmas (we now know) it got blocked up. She started developing neurological symptoms, and the only person who knew enough about her treatment to be able to sort it out was her doctor.
The actually had his home landline number, but he was away, and it was only due to luck of a call coinciding with the neighbour feeding the cat that they were able to get the number of where he was for Christmas. By that point, my aunt with unconscious in hospital, and might well have died if treatment had been delayed any more.
It's scary that sheer happenstance saved your aunt's life. I wonder how medical record keeping could be improved to help with that scenario.
In this case I think it was less knowledge of the particular case, and more the expertise in that specialised situation. Skillset rather than records.
There are a few special patients he'll give his cell number to. Pregnant moms especially I think. He's a country doc and the only good baby doctor within a hundred miles, so if there's an OB patient who he thinks is higher risk, and who he knows won't abuse his cell number, he'll give it to them no problem.
I'm sure that experienced doctors can spot people who are going to ruin every weekend a mile away, and also those responsible enough to call only when it really is appropriate.
Is this sideways dig really necessary? I could say the same about programmers (and I am one).
I count half a dozen doctors and nurses among my inlaws. None of them will give their personal phone numbers out to patients. If a patient asks, they're politely told to call the office, who will then curate the calls.
If you've ever been around a doctor, especially a GP, you know how many calls they get. My father-in-law takes dozens of calls a day from his office, several of which come at night when he's asleep. If he were expected to take calls directly from patients, he'd be completely unable to do his job.
So, serious question for you jachee: is it possible that the doctor you're responding to has some insight into the challenges of his job that you don't?
My brother-in-law is an ER doc. He treats an alarmingly high number of patients who threaten to sue him if he's not willing to give them his phone number, write an immediate referral, or prescribe opioids. These are patients with real pain, real problems, who are understandably desperate for relief, and who are easily capable of completely dominating a doctor's time and attention.
The implication of an obvious disdain for humanity here is pretty uncharitable. Just as it's difficult to relate to chronic disease from the outside, I think it's difficult to relate to the challenges of treating and caring for the afflicted.
I think you are wrong to make that assumption.
There are tons of people with no sense of boundaries who will make contact over and over for very little reason. It only takes one or two of those people to ruin it for the rest of us.
