Burden of Multiple Chronic Conditions among Patients with Urological Cancer.

PURPOSE

We describe age, multiple chronic condition profiles and health system contact in patients with urological cancer.

MATERIALS AND METHODS

Using Geisinger Health System electronic health records we identified adult primary care patients and a subset with at least 1 urology encounter between 2001 and 2015. The Agency for Health Care Research and Quality Chronic Condition Indicator and Clinical Classifications Software tools were applied to ICD-9 codes to identify chronic conditions. Multiple chronic conditions were defined as 2 or more chronic conditions. Patients with urological cancer were identified using ICD-9 codes for prostate, bladder, kidney, testis and penile cancer. Inpatient and outpatient visits in the year prior to the most recent encounter were counted to document health system contact.

RESULTS

We identified 357,100 primary care and 33,079 urology patients, of whom 4,023 had urological cancer. Patients with urological cancer were older than primary care patients (71 vs 46 years) and they had more median chronic conditions (7 vs 4). Kidney and bladder cancer were the most common chronic conditions (median 8 patients each). Coronary artery disease and chronic kidney disease were common in urological cancer cases compared to mental health conditions in primary care cases. Patients with urological cancer who had multiple chronic conditions had the most health system contact, including 32% with at least 1 hospitalization and 68% with more than 5 outpatient visits during 1 year.

CONCLUSIONS

Urology patients are older and more medically complex, especially those with urological cancer than primary care patients. These data may inform care redesign to reduce the treatment burden and improve care coordination in urological cancer cases.
