Objective: To determine whether individuals from surgery-specific service areas with a low supply of general surgeons (GSs) are at increased risk for ruptured appendicitis (ruptured appendicitis is an indicator of surgical access).
Background: The increased health care costs and morbidity linked to appendiceal rupture are considered preventable in most cases with timely access to surgery. Among the factors thought to affect an individual's access to surgery for appendicitis is the relative supply of GSs. The maldistribution of GSs is targeted by a Medicare bonus payment although the impact of GS supply on surgical access has yet to be fully described.
Methods: Patients discharged from acute care and ambulatory surgery facilities in North Carolina from 2007 to 2009 were pooled for observational analysis. Using ICD-9-CM (International Classification of Diseases, Ninth Revision, Clinical Modification) codes, cases were identified as ruptured or unruptured. GS shortage levels based on supply were calculated at the surgical service area level and tested for an association with an individual's risk of rupture using logistic regression.
Results: Living in a service area with less than 3 GSs per 100,000 people significantly increases the probability of rupture in individuals with appendicitis, compared with living in a service area with at least 5 GSs per 100,000.
Conclusions: The supply of GSs does affect access to surgical services for appendicitis. Expanding on this finding, the recently instituted HPSA (health professional shortage area) surgical incentive payment from the Affordable Care Act should be evaluated closely for its effectiveness. Enhancing supply in critical shortage areas could reduce appendiceal rupture and improve surgical access more generally.
The increased health care costs and morbidity linked to appendiceal rupture are considered preventable in most cases with timely access to surgery. General surgeon shortage levels based on supply were calculated at the surgical service area level and tested for an association with an individual–s risk of rupture using logistic regression. Enhancing supply in critical shortage areas could reduce appendiceal rupture and improve surgical access more generally.
