“…Evaluation of follow-up and outcome of the cohort was conducted by using two separate EMRs: The institute's (Chameleon, Elad Solutions Ltd. Tel Aviv, Israel) and an intergraded hospital-community online medical records system (Ofek database system, Clalit Health Services, Tel Aviv, Israel), which allows online access to imaging, pathological reports, lab reports, admissions, and community visits. 20 For validation, we cross-checked the data for all patients who underwent surgery in our institution, by confirming the diagnosis of surgery and pathology in the Ofek EMR. For each patient, the following was obtained: diagnoses made in the community clinic/hospitalizations (in our institution or others), history of surgeries, pathological reports, hospital admissions, and discharges, imaging, community physician visits, date of death, and reason of death for deceased patients.…”
