I was a PICU hospitalist between residency and fellowship. There are also CICU hospitalist roles. Columbia is an example of a place that has this and I'm sure others do as well. These do not require you to be fellowship trained. Many people do this for a year prior to starting PICU or CICU fellowship. If you like cardiology and want to understand if the CICU culture is the one for you, then maybe that's something to consider. Critical care fellowships are competitive and a lot of people come after doing a chief year so this is a way to avoid administrative work, build up your competitiveness, and decide if you love CICU or general PICU. For me, going from residency to almost a "gap year" helped solidify my interest in PICU, helped me gain some contacts, understand the dynamics of PICU, and also gave me some time off from rigorous training, earn some extra money, have a decent schedule where I could study AND pass my peds boards (so I didn't have to worry during fellowship when you are working WAY harder). There are also options to take a PICU hospitalist role after critical care fellowship and there are some people who would do that if it means they get to live in the place they want to be, are near family, maybe have a spouse who needs to be in a certain area, work a slightly less rigorous schedule, etc. There are more facets to life than money and you have to prioritize for yourself what is important to you. Personally I've had co-fellows who finished fellowship consider PICU/CICU hospitalist roles...agree that pay is less but maybe you're a new parent and can't do the crazy PICU schedule. Maybe you're restricted geographically. Maybe you need a break after a fellowship that is super demanding and emotionally/physically exhausting. Maybe you just need a job because, like the topic of this post, the market is trash. Who cares? The only person who lives your life is you.
CICU culture to me is the same everywhere. Not a walk in the park. Surgeons can be mean. Cardiologists can think of things differently and be helpful or not at all. PICU people have a different skillset and personally a more holistic approach because we have to think of cardiopulmonary interactions, the brain the kidneys and not only the heart. But some people thrive. VADs are cool. ECMO is cool. Heart failure and transplant and congenital heart disease is cool. Interventional is cool. But babies and children are sick and good and bad outcomes are everywhere. It's all about exposing yourself to it and understanding if you feel good in the environment or not.
As someone who went to a small place that has a community/academic feel after training at a big center, I can say I do miss the higher acuity. I do not miss the volume. I do not miss the challenging consultants. Here, I am able to teach pediatric residents and do research but on my own time and when I want to do it, without the pressure of having to have big grant funding. But I don't see ECMO/cardiac, I rarely do CRRT and I do miss being part of the care of those patients. I do not love the location of where I am and struggling to find ways to fill my spare time. I'm lonely. I miss my family. I am homesick. Sadly, there is no perfect job, and you can't have everything all at once. Hope this helps.
