Treatment Patterns in Metastatic Prostate Cancer

24. Januar 2018 aktualisiert von: Bayer

Treatment Patterns, Mortality, Healthcare Resource Utilization, and Costs in Patients With Prostate Cancer With Bone Metastases: A Retrospective Database Analysis .

This study will evaluate treatment patterns, mortality, healthcare resource utilization, and costs in patients with prostate cancer with bone metastases (primary objectives). Additionally, this study will evaluate opioid/analgesic use among lines of therapy in this patient population (secondary objective). The study is descriptive in nature and is meant to provide a greater understanding of the patterns of therapy observed in real-world clinical practice (in the absence of clear guideline recommendations with regards to treatment sequencing), to contribute to a greater understanding of the major cost drivers (thus better-informing payers), and to examine real-world mortality in such patients.

Studienpopulation

Part 1 - Assessment of treatment patterns, healthcare resource utilization, and costs The study cohort will include all patients with prostate cancer with incident bone metastases during the index period (1 June 2013 to 1 July 2014) based on a large database encompassing a broad sample of the commercially insured U.S. population. The first date of bone metastases diagnosis or first date of treatment indicative of bone metastases (whichever occurs first) will be designated as the index date.

Part 2 - Assessment of mortality The study cohort will include all patients with prostate cancer with incident bone metastases during the index period (1 June 2013 to 1 July 2014) based on a large database encompassing a broad sample of the commercially insured U.S. population. The first date of bone metastases diagnosis or first date of treatment indicative of bone metastases (whichever occurs first) will be designated as the index date.

Beschreibung

Inclusion Criteria:

- Subjects with at least one claim with a primary diagnosis of prostate cancer (International Classification of Diseases(ICD) Clinical Modification (CM)185.xx )and any of the below on same day or after the prostate cancer claim:

  • At least one inpatient claim with a primary or secondary diagnosis indicating bone metastases (ICD 9 CM 198.5 or Healthcare Common Procedure Coding System (HCPCS) code for a treatment indicative of bone metastases OR
  • At least two outpatient claims with a primary or secondary diagnosis indicating bone metastases (ICD 9 CM 198.5 or HCPCS code for a treatment indicative of bone metastases, with a minimum of 30 days between claims.

Exclusion Criteria:

  • Subjects with a diagnosis of a cancer other than prostate cancer - defined as the presence of one inpatient or two outpatient claims with a primary or secondary diagnosis of malignant neoplasms (ICD-9-CM 140.xx-171.xx, 174.xx-184.xx,186.xx-195.xx,200.xx-209.3x, 230.xx-239.xx) - in the 12-month pre-index period.
  • Subjects with any claim for a primary or secondary diagnosis indicating bone metastases (ICD-9-CM 198.5) or any treatment indicative of bone metastases in the 12-month pre-index period.
  • Patients who had a SRE in the 12-month pre-index period.
  • Subjects without continuous enrollment for at least 12 months before the index date.
  • Subjects without continuous eligibility for at least 6 months after the index date.
  • Subjects that are female.
  • Subjects that have negative costs.
  • Subjects that are less than 45 years of age on the index date.

Treatment patterns, healthcare resource utilization and costs
Part 1 - Assessment of treatment patterns, healthcare resource utilization and costs. The study cohort will include all patients with prostate cancer with incident bone metastases during the index period (1 June 2013 to 1 July 2014) based on a large database encompassing a broad sample of the commercially insured U.S. population. The first date of bone metastases diagnosis or first date of treatment indicative of bone metastases (whichever occurs first) will be designated as the index date. All patients must have no diagnosis of other cancers, no diagnosis of bone metastases or a claim for a treatment indicative of bone metastases, and no skeletal-related events (SREs) in the 12-month pre-index period. Additionally, all subjects must be continuously enrolled for at least 12 months before and at least 6 months after the index date.

Retrospective claims analysis. Descriptive analyses of treatment patterns.
Mortality
Part 2 - Assessment of mortality. The study cohort will include all patients with prostate cancer with incident bone metastases during the index period (1 June 2013 to 1 July 2014) based on a large database encompassing a broad sample of the commercially insured U.S. population. The first date of bone metastases diagnosis or first date of treatment indicative of bone metastases (whichever occurs first) will be designated as the index date. All patients must have no diagnosis of other cancers, no diagnosis of bone metastases or a claim for a treatment indicative of bone metastases, and no SREs in the 12-month pre-index period. Additionally, all subjects must be continuously enrolled for at least 12 months before the index date. Unlike in Part 1, there will be no required minimum follow-up time after the index date (in order to assess mortality).
