Table 2 Description of the independent variables
Independent variables | Definition |
|---|---|
Surgeon | Professional that performs the surgery. |
Sociodemographic variable | This includes the age and the gender. |
American Society of Anesthesiologists (ASA) | The surgical risk that a patient can experiment according to the measuring scale of the American Society of Anesthesiologists. The ordinal scale from ASA I to ASA V. |
Type of surgery | Osteoarticular surgeries with or without implants and nails or skin surgery. |
Fulfillment of the Informed Consent | It measures the correct fulfillment of the informed consent, codified in complete, incomplete or nonexistent. |
Identification of the surgical site | It measures the correct identification of the anatomical site where the surgical procedure is going to be performed in the medical history. When the identification is correct, it is codified with a YES, or NO when it is incorrect. The reasons of a NO codification can be an inconsistency of the identification of the surgical site between the documents, or the anatomical site of the operation is not identified, or a surgery has been performed in the wrong site. |
Fulfillment of the DVT Prophylaxis Protocol (DVTPP) | This is applied to patients undergoing surgery and assesses the risk of a thromboembolism. On the other hand, it measures the level of compliance of the protocol. A “Secure” codification is given to the patient when the assessment page of DVTPP risk is completed, when a DVT prophylaxis is required or when the assessment is completed and the patient does not require it or prophylaxis is not established as a treatment. The rest of the variations are considered insecure practices. |
Correct use of the antibiotic prophylaxis | Antibiotic prophylaxis is require when the patient presents 3 or more risk factors (≥65 years, Diabetes Mellitus, malnutrition, obesity, ASA ≥ 3, smoking habits, coexistence of the infection in other locations, immunosuppression and radiotherapy treatment) in the cases of surgery with osteosynthesis materials. It is considered a secure practice when the subjects require antibiotic prophylaxis and it is established as a treatment; or when, on the contrary, the antibiotic prophylaxis is not required or established. |
Infection of the surgical site | This happens when clear signs of infection are described in the medical history (such as pain, swelling, suppuration, erythema, redness) or when a local or oral antibiotic is prescribed during the postsurgical process. |
Postoperative days | From the days of the operation till the date of discharge. |
