Detail description:
OP-KISS Module (surveillance of surgical patients). OP-KISS offers a standardised method for conducting structured surveillance of patients undergoing surgery. OP-KISS is primarily used to record surgical site infections (SSI). In addition to SSI, postoperative lower respiratory tract infections can optionally be recorded. The assessment of whether an infection is present is based on the KISS definitions and the methodological specifications in the OP-KISS protocols. In order to enable comparability of the infection rates of different departments, the infection rates for different types of surgery are analysed separately. OP-KISS focuses on selected procedures that are performed frequently or for which SSI are particularly relevant (so-called indicator procedures). The departments participating in OP-KISS select one or more indicator procedures from a catalogue comprising over 30 indicator procedures from different surgical specialties. The indicator procedures are defined by their procedure codes (OPS codes) and in some cases also by their ICD diagnosis codes. Each patient for whom a selected indicator procedure was performed is followed up postoperatively. A maximum duration of surveillance (30 or 90 days) is defined for each indicator procedure. Reoperations and the death of the patient end the surveillance early. Both SSI that occur during the inpatient stay and those that occur after hospital discharge, are recorded. Risk stratification is used to consider the different composition of the patient population in different hospitals and to determine the individual risk of a patient based on known risk factors. The internationally used NNIS risk score is applied, which considers the duration of surgery, the patient's ASA score and the wound class. This data is collected for each included procedure. For some types of surgery (e.g. appendectomy, cholecystectomy, colon surgery), separate SSI rates are also calculated for laparoscopic and open surgery. The NRZ provides KISS participants with an electronic system for documenting surveillance data (webKess). In addition to manual entry via the webKess user interface, data can be imported to the OP-KISS database. The corresponding specifications can be found at " Data import". Departments wishing to participate in OP-KISS must first complete an introductory course in which the surveillance method is explained in detail and trained using example cases. Interested parties can find the dates for the next introductory courses on the NRZ homepage under "Events".
