The following data were prospectively collected and maintained in surgical surveillance databases: patient age, type of procedure, date of surgery, length of procedure, type of procedure, wound classification, American Society of Anesthesiologists (ASA) score, NNIS risk index score, and, if SSI was present, pathogen, anatomic site of infection, and date of culture [15].
Almost factors were dichotomous: sex, immune-compromised status, exposure to invasive device and to surgical procedure, type of stay.
Patient demographics, indications for the procedure, type of procedure, size of the implant placed, duration of follow-up, any complications encountered and patient management procedures were recorded.
For diagnosis, procedure, or pharmacy events occurring on the same day, patients are classified first according to the diagnosis, and in the absence of a diagnosis code, according to procedure, and in the absence of a procedure, type of pharmacotherapy.
Multiplicative interaction with POAF was tested for the following predefined variables: type of surgical procedure, type of underlying valvular dysfunction (regurgitation vs stenosis), severity of CAD and mechanical-valve implantation.
The outpatient datasets contained the encounter form-based dates of visit, three items from the International Classification of Diseases (Ninth Revision, Clinical Modification codes), the primary procedure (e.g., drug or diagnostic procedure), type of copayment, billed amount, and paid amount.
The following data were collected: age, sex, severity scores, admission category (medical or surgical), underlying diseases, antibiotic exposure within 3 months before ICU admission, invasive procedures, type of ESBL-PE, and outcome.
Clinical variables from the records include age, surgical procedures, type of adjuvant therapy, recurrence, and progression-free survival (PFS).
Age, gender, demographic data, body mass index, Mini Mental State Examination (MMSE) scores, diagnostic procedures, type of dementia disorder and treatment are recorded in this web-based registry.
This national program uses standardized development and validation methodology, data-collection procedures, type of questions, response scale, and scoring and case-mix system [ 31– 31].
This introduced an unusually high level of variability in this study in terms of the test procedures, type of patients or subjects, type of examiners, and types of disorder.
