The Impact of Comorbidity on Outcomes

Abstract: Patients often have other diseases, illnesses, or conditions in addition to the disease under study. These other medical conditions are referred to as comorbidity. Comorbidity can impact on diagnosis, prognosis, and selection of therapy. There are a variety of instruments available to measure the type and severity of comorbid ailments. Comorbidity information can be obtained from direct discussions with the patient, a review of the medical record, or from electronic databases that contain billing information. … Show more

“…In our study, we did not apply standard comorbidity measures as the Adult Comorbidity Evaluation-27, that are currently used in studies to code and quantify comorbidity. [42][43][44] Nevertheless, we were able to indicate that comorbidity apparently played a larger role in decreased QOL scores than radiotherapy. However, 2 patients received radiotherapy between T 2 and T 3 due to recurrent disease.…”

“…Another ecological measure included percent of the population that was in an urban area (100% urban, 100% rural, urban/rural mix). Comorbidities were assessed using the Adult Comorbidity Evaluation (ACE)-27, which includes conditions relevant to cancer treatment choice and outcome, and the severity of these conditions that were present at or before diagnosis [22,23]. Overall comorbidity index (none, low, moderate, or severe) was allotted based on the comorbidity with the highest level of decompensation.…”

“…Medical records were reviewed for patient demographics, tumor site and stage, treatment, morbidity during and after treatment, and follow-up. Comorbidity was assessed using the Adult Comorbidity Evaluation 27 Index (ACE-27) [12]. …”
