Evaluating treatments and corresponding costs of prostate cancer patients treated within an inpatient or hospital-based outpatient setting.

AIM: To describe treatments and cost of care for prostate cancer (PCa) in hospital-based outpatient and inpatient settings. METHODS: Hospital encounters associated with PCa (ICD-9 codes 185, 233.4) and PCa-related treatment in a hospital claims database were included. RESULTS: There were 211,440 encounters for PCa between January 2006 and December 2010 (88,151 inpatient and 123,289 outpatient). Average cost per inpatient stay was US$12,286 versus US$4364 per outpatient visit. Most common treatment during an inpatient stay and outpatient visit was surgery (57%) and radiation (76%), respectively. A total of 80% of outpatient visits and 69.9% inpatient stays were associated with a single treatment; remaining encounters were associated with ≥2 treatments. CONCLUSION: Costs are consistent with previous estimates; however, multimodal therapy is an emerging trend that may be related to greater costs in the future which may also be a challenge for hospital decision makers.

Comparing hospital-based resource utilization and costs for prostate cancer patients with and without bone metastases.

BACKGROUND: Since 2010, several new treatments for prostate cancer (PCa), which have entered the US market, are poised to have an impact on treatment approaches; however, there is a paucity of evidence with respect to treatment patterns and costs. As new treatment patterns emerge, it will be imperative to understand treatment patterns and costs of care prior to the advent of novel treatments. OBJECTIVE: As the PCa treatment landscape is evolving, this study sought to compare the hospital-based utilization and costs in two cohorts of patients with PCa: patients with bone metastases (w/BM) and patients without bone metastases (w/oBM). Comparisons were also made for patients with inpatient versus outpatient encounters. METHODS: Patients in the Premier Perspective Database, a US hospital database, between January 2006 and December 2010, treated in an inpatient or outpatient setting for PCa (International Classification of Diseases, 9th Revision [ICD-9] diagnosis codes 185, 233.4) were included. Patients were required to be ≥40 years of age with no additional cancers. Patients were put into cohorts on the basis of the presence of bone metastases (ICD-9 code 198.5 or use of zoledronic acid or pamidronate disodium). Utilization of PCa-related treatments was compared, controlling for age, race, hospital type, payer type, bed size, and admission source and type. Differences in treatments were assessed utilizing logistic regression, while differences in costs were analyzed using gamma-distributed generalized linear models with a log-link function. All costs are reported in US$ 2010. RESULTS: There were 23,747 hospitalizations for men w/BM (13,716 inpatient; 10,031 outpatient) and 187,708 hospitalizations (74,435 inpatient; 113,258 outpatient) for men w/oBM. The mean length of stay for men w/BM was 4 days compared with 2 days for men w/oBM (P < 0.0001). Overall, the mean cost per encounter was US$9,728 in men with w/BM and US$7,405 in men w/oBM (P = 0.0006). For inpatient stays, the mean cost per encounter was US$14,145 for men w/BM and US$11,944 for men w/oBM. For outpatient visits, the mean cost per encounter was US$3,688 for men w/BM and US$4,422 for men w/oBM. Men w/BM received hormone therapy (44.3%) and secondary hormone therapy (46.4%) most often, while men w/oBM received radiation (48.8%) and surgery (31.9%) most often. CONCLUSION: Costs and utilization of PCa-related treatments vary on the basis of the presence of metastases and treatment setting (inpatient vs. outpatient).

Systemic therapy for colorectal cancer: patterns of chemotherapy and biologic therapy use in nationally representative US claims database.

BACKGROUND: Treatment strategies for colorectal cancer (CRC) are highly variable. The aim of this study is to examine the patterns of chemotherapy and biologic therapy use for CRC patients in a national medical claims database. METHODS: A retrospective and observational analysis was performed using the i3 Innovus claims database to identify healthcare services consumed by patients aged 18 years and older, diagnosed with CRC between 1 January 2005 and 30 June 2009 in commercial health plans. RESULTS: Of 9,876 subjects diagnosed with CRC, fluorouracil (23.5 %) and capecitabine (10.0 %) were the dominant first-line monotherapies, followed by bevacizumab (3.2 %) and oxaliplatin (2.9 %). The most common combination regimen at first line and first and second line was FOLFOX (fluorouracil, leucovorin, and oxaliplatin; more than 25 %). The combinations FOLFIRI (fluorouracil, leucovorin, and irinotecan) plus bevacizumab (14.2 %) and FOLFOX plus bevacizumab (13.9 %) were significantly more frequent in third and successive lines of CRC therapy than other regimens (χ(2) = 191.2; P < 0.01). Additionally, the average annualized cost of CRC treatment for all patients was $US66,452, and the adjusted analysis demonstrated that patients receiving FOLFOX-A (FOLFOX + avastin) or FOLFIRI-A (FOLFIRI + avastin) had higher costs for CRC treatment. CONCLUSIONS: With the exception of a sizeable portion of patients on monotherapy, the treatment patterns for CRC were largely consistent with National Comprehensive Cancer Network (NCCN) guidelines.

Medical costs associated with use of systemic therapy in adults with colorectal cancer.

BACKGROUND: New cytotoxic agents and regimens, as well as immunotherapeutics, have recently been introduced for treatment of colorectal cancer (CRC).  OBJECTIVE: To identify the patient-related and clinical and treatment-related factors associated with higher total health care expenditures in newly diagnosed patients with CRC who are receiving systemic therapy (biologic or chemotherapy) from a commercially insured population.  METHODS: A longitudinal, retrospective analysis was employed to estimate costs and determinants of CRC treatment in a U.S. claims database for health care services used by commercial patients aged 18 to 64 years, who were diagnosed with CRC between January 1, 2005, and June 30, 2009. Generalized linear regression modeling was used to estimate the influence of demographic, clinical, and treatment factors on medical expenditures.  RESULTS: Among the 5,160 patients newly diagnosed with CRC, 99.6% of patients had chemotherapy; 32.6% had biologics; and 85.6% had other pharmaceuticals (excluding the chemotherapy and biologics of interest). The average annualized per patient cost of CRC treatment was $97,400 and consisted of chemotherapy ($17,500), biologics ($30,400), other pharmaceuticals ($2,300), inpatient treatment ($26,300), and outpatient treatment ($42,900). From first line only, first and second lines only, and third+ lines, the cost per patient was $70,500, $100,100, and $152,900, respectively. After adjusting for health care inflation, the average treatment cost of CRC patients increased by 73% from 2005 to 2009. Adjusted analyses showed that the higher medical cost for CRC patients was associated with use of new regimens, metastasis, comorbidities, surgery, radiation, insurance plan, age, sex, and region.   CONCLUSION: The health care cost of CRC treatment is increasing significantly over time, which is most likely caused by the use of new regimens, higher chances of surgery and radiation, and occurrence of various comorbidities and metastatic diseases due to increasing survival time.

Productivity cost benefit to employers of treating migraine with rizatriptan: a specific worksite analysis and model.

Employers in the United States might not be aware of the productivity costs of migraine or the extent to which those costs can be reduced by optimal treatment. An economic model was developed to enable employers to estimate the productivity costs of migraine to their company and the savings that will accrue if those patients who suffer from migraine are treated with rizatriptan. Analyses were run for both a major financial services corporation and a representative U.S. company. The major financial services corporation, with 87,821 employees, is projected to lose 538 person-years annually, at an estimated cost of 23.8 million dollars. A representative U.S. company with 10,000 employees is projected to lose 46.0 person-years of productive effort annually as a result of migraine, valued at approximately 1.94 million dollars. The value of the annual work loss avoided if migraine is treated with rizatriptan is projected at 10.3 million dollars for the financial services corporation and 841,000 dollars for the representative U.S. company. There is a substantial productivity cost burden of migraine from a U.S. employer perspective. These productivity costs can be reduced significantly by treating migraine headaches with rizatriptan.
