van Ramshorst et al developed a model for predicting the risk of abdominal wound dehiscence in an adult. This can help to identify a patient who may benefit from more aggressive management. The authors are from Erasmus University Medical Center in Rotterdam, the Netherlands.
Patient selection: adult with a surgical abdominal incision, excluding routine appendectomies
Outcome: wound dehiscence
Parameters:
(1) age in years
(2) gender
(3) chronic pulmonary disease
(4) ascites
(5) jaundice
(6) anemia
(7) emergency surgery
(8) type of surgery
(9) coughing
(10) wound infection

where:
• Within each type of surgery there is a range of complexity.
• The other category included liver, kidney, pancreas, spleen and adrenal gland (page 22).
