Estimating cost of prostate cancer management: an experience from Tanzania

Abstract

Prostate cancer (PC) is a significant public health problem affecting men worldwide and ranks third in incidence and mortality in East Africa. Cost of prostate cancer management is high in low-income countries because majority of patients presents with advanced (metastatic) PC. The cost related to management of PC including castrate resistant cancer in Tanzania has remained unknown; hence, policy makers do not have enough information for planning and resource allocation. This study therefore aimed to document costs related to the management of patients with prostate cancer including castrate resistant prostate cancer (CRPC) at Muhimbili National Hospital in Tanzania. This was a retrospective descriptive hospital-based study which was conducted at Muhimbili National Hospital (MNH). Case notes of patients who were treated for prostate cancer were retrieved from medical records for review. A structured checklist was used to extract information regarding age, clinical presentation, investigations, stage of disease, type of treatment, payment modality and reimbursement. We considered data on the direct costs of prostate cancer management (diagnosis, treatment and follow-up) based on hospital price list of different categories. Costs reported were based on payment category in total and unit cost but also source of funding. Descriptive statistics were prepared and summarized as tables and figures. A total of 292 case notes of patients with prostate cancer were reviewed of which 189 patients received androgen deprivation therapy. Ninety-six (50.8%) met the criteria for the diagnoses of CRPC, and their mean age was 71.23 ± 4.2. Most of the patients had a poorly differentiated histology with prostate-specific antigen (PSA) over 100 ng/l. Bilateral orchiectomy was the most common treatment modality offered for advanced prostate cancer. Total cost for all PC patients was $148,136.4, equivalent to a unit cost per patient of $507.3. However, patients were in different categories of payment, 53% were public patients with an average cost of $471.3 per patient; 36.6% were cost sharing patients with an average cost of $441.8 per patient; 8.2% were National Health Insurance (NHIF) patients with an average cost of $893.8 per patient; and only 2.2% were private patients with an average cost of $1060.9 per patient. Costs related to prostate cancer management need harmonization to accommodate different categories of patients in need.
