I took a rather long and convoluted path to get to critical care and in hindsight I would have done things differently. I did my residency in internal medicine and initially I did not have an idea about what I would do in future. By third year of residency I became interested in nephrology. I though at that time wanted to fix my visa and therefore I became a hospitalist .
Hospitalist jobs especially visa jobs are very busy and after 4 years I was quite burned out. After getting my green card I applied and got into nephrology. Nephrology is simple as a field but the job prospects , the driving around and low salaries are a major drawback. At the end of fellowship I got an opportunity to do a critical care fellowship and took it. Now I work as an intensivist . The job by itself is pretty good and pay is much better than nephrology ( although not much better than hospitalist ) , not busy but the CC part is a killer. Patients are sick , families are upset and worried and sometimes you have a young patient who is going to have a bad outcome and there is absolutely nothing you can do about it. You are constantly hustling and yet you will find other specialities that you depend on i.e GI , heme/onc , IR , surgical specialities dragging their feet and slowing care. The goals of care discussion wear you down after a while .
Ideally I would do part time nephrology and part time CC but unfortunately there are hardly any neph - CC jobs. The job market for straight CC is OK but not as good as pulm - CC . If I had done pulm CC and sleep I would probably do 1 in 4-6 weeks of CC and get some time to decompress in output clinic and read sleep studies. And as I time went by and I grew older I would cut back on the CC and transition to more output stuff. But I don't have that option , so I am not sure what I will do when I am 50. If anyone asks me what I would do I would always advise do pulm - CC not straight CC.
