The Postsurgical Clavien-Dindo Classification in Minor Surgery Can Improve Perception and Communication (Investigation on Blepharoplasty).

The postsurgical Clavien-Dindo classification in minor surgery can improve perception and communication (Investigation on Blepharoplasty). Background: Minor surgery lacks a standardized postoperative complication classification. This leads to the presentation of inaccurate postsurgical complication rates and makes comparisons challenging, especially for patients seeking information. This study aims to evaluate a standardized five-step complication grading system (Clavien-Dindo Classification, CDC) on the example of blepharoplasty, which is the most performed minor aesthetic surgery worldwide. Methods: A retrospective observational exploratory study of patients (N = 344) who received a bilateral upper eyelid blepharoplasty under local anesthesia from the same surgical staff was performed. Data were retrieved from the electronic patient record: the CDC grading and the surgeon-reported complications (N = 128) at the first follow-up on day 7. In addition, a telephone survey with patients (N = 261) after 6 months was performed, which consisted of 7 complication-related yes/no questions. Results: Based on the CDC, 41.6% of patients were classified as having no complications, and 58.4% had one. Furthermore, 1 patient (0.3%) received a revision under general anesthesia (CDC IIIb), 18 patients (5.2%) were re-operated under local anesthesia (CDC IIIa), 23 patients (6.7%) required pharmacological intervention (CDC II), and 159 patients (46.2%) had a complication from the normal postoperative course and received supportive treatment (CDC I). Moreover, 90.5% of the mentioned complications accounted for Grade I and II; 94% of the patients subjectively experienced no complications; 51% of patients were pleased with the surgery even though a complication occurred according to the CDC; 34% of complications escaped the awareness of the surgeon. Conclusions: Grade I and II complications occurred frequently. Complications escaped the perception of the patients and surgeons. The classification identifies a wide variety of postsurgical complications and allows a standardized comparison in minor surgery objectively. Potential: The CDC in minor procedures can improve the (institutional) preoperative communication with patients regarding potential postoperative expectations. Furthermore, the classification can be a useful tool to detect complication-related costs, identify insurance-related requests, and support evidence in medicolegal disputes. The example of blepharoplasty can be translated to various other and even less invasive procedures.
