This is an interesting article comparing mortality based on physician's age, however, there are several flaws in the study.
I have worked as a hospitalist and I am familiar with the work flow of the hospitalist as well as intensivist.
1. In comparison to the UK system (in no way do I want to derecognize the contributions of hospitalists), hospitalists depend mainly on subspecialists for most of the problems. Role of hospitalist many times is reduced to "following the recommendatios" only. When hospitalist is identified as primary biller, likely there are two options. Either they did not use a subspecialist or patient was not too complex. In other words, if a patient dies from GI bleed, you have to blame the GI specialist, not the hospitalist.
2. Most deaths in hospital happen in intensive care units in the USA. Those who die on the wards (floor) are either deemed to be at the end of life or DNR. There is no mention of intensive care in this study. Invariably, an intensivist will be involved in the care at the time of death.
3. There is no exclusion of withdrawal of care as well because that will increase the mortality of a physician.
4. Study was also limited to those older than 65 and cannot be generalized to all age population.
This study is poorly designed and seems to malign the age of the physician as part of outcome.
