Clarifying the Role of the Modern General Surgeon: The Effect of Specialization on Inpatient Practice Patterns in...

The growing concentration of fellowship-trained and integrated residency-trained subspecialty surgeons has encroached on the breadth and volume of a so-called "true" general surgery practice, leaving the role of new general surgeons in flux. We aimed to describe the surgical practice of new general surgeons with and without subspecialty fellowship training.

In this retrospective cohort study, state discharge data was linked to American Medical Association Masterfile and American Hospital Association annual survey data. New-to-practice general surgeons with and without subspecialty board-certification in colorectal surgery (CRS) or cardiothoracic surgery (CTS) were identified in 2008, and followed over 10 years. Surgeon overall inpatient case volume, colorectal resection case volume, and thoracic lobectomy case volume were compared between surgeons with and without related subspecialty training.

NY and FL (2008-2017).

The study population included 276 new-to-practice surgeons with mean age of 36.9 years. New-to-practice surgeons were defined as those with zero to three years of experience in 2008.

Of all surgeons, 11.2% were subspecialty board-certified in CRS and 11.6% were subspecialty board-certified in CTS. Board-certified CRS surgeons performed more colorectal resections than the non-CRS general surgeons each year (p-value <0.001 for all). Overall, non-CRS general surgeons performed 60.7% of all colorectal resections. Board-certified CTS surgeons performed more thoracic lobectomies than non-CTS surgeons each year. Non-CTS surgeons performed 1.1% of all thoracic lobectomies.

On average, new subspecialty surgeons perform significantly more specialty operations than non-subspecialty new general surgeons. However, as a group, new non-colorectal general surgeons perform the majority of colorectal resections. In contrast, new non-cardiothoracic general surgeons perform less than two percent of the thoracic lobectomies. This may have implications for a shift in the training paradigm going forward.
