I have experience of hospital medicine, obviously, both as a junior doctor, as a Psychiatrist and because my husband and many of my friends are hospital consultants. I have been a GP for eleventy billion years now and love it.
I work in a small GP practice and it is only as isolated as you make it. We all have a coffee break together after morning surgery and have a good old moan about everything
I see people constantly, to the extent I like a bit of peace and quiet, practice nurses, receptionists, admin, district nurses, counsellors, dietitian, podiatry, nurse practitioners are all in and out all the time. Med students and FY2s during the season. Calls from Consultants most days, plus social workers, physios, OTs. That is without around 30 patients who are in a very different situation to when they are in hospital, in that they are usually (relatively) well, so treat me as a person rather than a job title and know (sometimes) more about my life than some of my friends, as I do theirs, so these are social as well as professional interactions - award winning gingerbread and a delayed bar of Dairy Milk as it was my birthday last week came in today. Along with sticky buns picked up by our Frailty Co-ordinator and copious cups of coffee lovingly made by the staff (who joking aside are hugely supportive, hepful and loyal). My work partner and out Practice Manager are now two of my very best friends and we have total autonomy to do the work we want in the hours we want to do it. Having said that, I would like to dispel this myth that GP is a better work/life balance. It might be easier to go LTFT earlier, but our core hours are now 8 until 8, 7 days a week. We have to provide the service from 8-6.30 Mon to Fri and the rest can be out-sourced (at a cost). I am out of the house far longer than my husband on a normal working day and his 1 in 12 on call does not make up for the fact I do 8.30 to 7.30 on my working days (he does around 8.30-9 until 5.30-6).
A bigger practice would bring more people to mix with and probably more flexibility regarding hours, but the core hours still have to be covered by someone!
As a student, it is hard to become part of the team, especially in a bigger practice, but once qualified, you can choose the people you work with who provide as much (or as little) interaction as you want. We work hard to integrate our med students, but in a team of about 18, that is easy to do and every one of them has said how much they enjoyed it, as well as how much they learned, in feedback.
And I really do not see how you can get a more varied and unpredictable working day, other than in A&E. Literally, something different comes through the door every 10 minutes! I have had polymorbidity x about 10 (COPD, diabetes, IHD, CCF) today, a schizophrenic, someone who wanted referral to the Gender Identity Clinic, a child with cows milk protein allergy, a cold, a perineal hernia (with the gingerbread), pleurisy, a new diagnosis diabetic, a sub-acute obstruction (with the chocolate), a pelvic pain, gallstones, a palliative visit, a bereavement visit and that is just off the top of my head from today. I cannot think of anything worse than a chest pain clinic, an IBD clinic, an epilepsy clinic, a COPD clinic, a Psych clinic - how repetitive and boring!
