Summary

The general decolonization of the human body surface by industrial antiseptic agents, before elective surgery is recommended by the World Health Organization (WHO). A specific randomized-controlled trial specifically among high-risk adult orthopedic patients for infection has not been performed. In this single-center, prospective, randomized, and controlled superiority trial, which is planned over a period of two years, we target on an orthopedic patient population with an elevated risk for revision surgery and surgical site infections

Detailed description

The general decolonization of the human body surface and, of adjacent pathogen reservoirs such as the nose, by industrial antiseptic agents by the World Health Organization (WHO) for the risk reduction of superficial and deep surgical site infection (SSI). Such a decolonization is regarded as evidence-based in the majority of randomized, and before-after trials, since two decades, although negative studies also exist. In the orthopedic field, this decolonization is likely to be more effective in elective patients with a proven body colonization of Staphylococcus aureus. The decolonization might be equally efeective in orthopedic patients with an inherent high risk for SSI, for which the majority of future SSI pathogens are skin commensals and S. aureus. These (eventual and future) pathogens of SSI are accessible to the topical agents during the index surgery, if the patients are well instructed and know how to decolonize themselves. In contrast, this pre-surgical decolonization is only a supplementary measure in the bundle of all combined efforts to prevent revision surgery for infection. Its individual power is limited for young, healthy individuals, for SSIs caused by pathogens from the internal body sites (intestinal, urinary, gynecologic regions), infections acquired on the surgical ward, and in settings with less specialized surgeries and a low volume of surgical experience. Hence, in trials including all patients (or only those carrying S. aureus), the beneficial effect of decolonization can be diluted and provoke an additional costly and cumber-some organizational procedure for the majority of patients with low to moderate SSI risks. Moreover, many surgical site infections in orthopedic surgery, especially in implant-related surgery, are more due to coagulase-negative staphylococci (CoNS) than for S. aureus. The hallmark of the CoNS group is S. epidermidis with approximatively 70% resistance (in Switzerland) to standard prophylactic antibiotic agents9, As S. epidermidis is part of the normal human flora, typically the skin flora, and, only becomes pathogenic under certain conditions, a screening for this microorganism is not feasible in common practice,. while the prophylaxis-resistant part of all orthopedic SSI pathogens is at 30-50%. In this single-center, prospective, randomized, and controlled superiority trial, which is planned over a period of two years, we target on an orthopedic patient population with an elevated risk for revision sur-gery and SSI; inde-pendently of a known body carriage for S. aureus. This study will be performed with an existing "set" manufactured by Schülke \& Mayr GmbH. The "Set" was placed on the market in 2016. The distribution of Octenisan® wash lotion and Octenisan® nasal gel in the form of a set (Octenisan® Set) largely streamlines and facilitates the organizational application and compliance efforts of the study. Academically and clinically, we will gain insight in the performance of decolonization for a patient population at particular risk of postoperative complications, where every effort to prevent infection is of importance.

Conditions

• Elective Surgery
• High Risk
• Prevention of Surgical Site Infections
• Randomized-controlled Trial

Interventions

Type	Name	Description
DRUG	Whole Body and nasal decolonization with octenidin (Octenisan Set)	Octenidin body lotion once a day during the five consecutive days preceding the elective orthopedic surgery, including for the hair. Octenidin nasal creme 2-3 times a day in both nasal orifices during the same period
BEHAVIORAL	Questionnaire for study participants immediately after the decolonization	A questionnaire in GErman language will be handed out to decolonized patients with five questions: Practical difficulties of decolonization, the completeness of scheduled decolonization actions, all adverse events during decolonization and surgery, and two questions regarding the comprehension of the science (indication for decolonization, potential benefit expected in the individual case). The questionnaire is handmade and validated by the Investigators.
