Timing of Complications following Hand Surgery.

Introduction  Our purposes were to (1) characterize the timeline of eight postoperative complications following hand surgery, (2) assess complication timing for the procedures that account for the majority of adverse events, and (3) determine any differences in complication timing between outpatient and inpatient procedures. Materials and Methods  Patients undergoing hand, wrist, and forearm procedures from 2005 to 2016 were identified in the National Surgical Quality Improvement Program database. Timing of eight adverse events was characterized. Cox proportional hazards modeling was used to compare adverse event timing between inpatient and outpatient procedures. Results  A total of 59,040 patients were included. The median postoperative day of diagnosis for each adverse event was as follows: myocardial infarction 1, pulmonary embolism 2, acute kidney injury 3, pneumonia 8, deep vein thrombosis 9, sepsis 13, urinary tract infection 15, and surgical site infection 16. Amputations, fasciotomies, and distal radius open reduction internal fixation accounted for the majority of adverse events. Complication timing was significantly earlier in inpatients compared with outpatients for myocardial infarction. Conclusion  This study characterizes postoperative adverse event timing following hand surgery. Surgeons should have the lowest threshold for testing for each complication during the time period of greatest risk. Level of Evidence  This is a therapeutic, Level III study.
