[A department of general surgery using the Diagnosis Related Groups (DRGs) system. Evaluation of the case series]. / Una Divisione di Chirurgia Generale mediante il sistema Diagnosis Related Groups (DRGs). Valutazione della casistica.

Therefore this grouping method is useful for payment to hospitals. The Authors have coded with DRGs the surgical activity of a general surgery staff during a year to verify the image that DRGs bears. Seven hundred diagnoses of dismission were related to operated on patients while one hundred twenty seven were related to patients treated with medical therapy. The DRGs more numerous were 290, 258, 198, 162, related with thyroidectomy, mastectomy, cholecystectomy and herniorrhaphy.
