Cost of image-guided percutaneous nephrostomy among cervical cancer patients at Muhimbili National Hospital in Tanzania

BACKGROUND: Most cervical cancer patients in developing countries seek care in health facilities with an advanced disease, often characterized by obstructive uropathy. This study aims to estimate the cost of an image-guided percutaneous nephrostomy (PCN), which was recently introduced at Muhimbili National Hospital to manage obstructive uropathy. METHODS: This was a cross-sectional study that was conducted between February and June 2021, from the provider’s perspective. The study involved forty-eight (n = 48) cervical cancer patients with obstructive uropathy. A micro-costing approach was used to identify, quantify and value both capital and recurrent cost items consumed by the patients. Cost data were collected in Tanzanian shillings and converted to USD with the relevant exchange rate. Analysis was performed in Microsoft Excel (Microsoft Excel®, Microsoft Corporation). RESULTS: The unit cost of image-guided PCN at Muhimbili National Hospital was estimated at 380.4 USD. The main cost drivers were the single-use Nephrostomy catheters, Amplatz guide wire, and Micro-puncture set. The estimated unit cost is higher than the reimbursement price of 237.4 USD charged by the National Health Insurance Fund, and the 259.4 USD and 172.9 USD charged by the hospital for private and public patients, respectively. CONCLUSION: Image-guided PCN for cervical cancer patients costs three times the minimum monthly government wage. The study underscores the importance of conducting costing studies to inform pricing and reimbursement decisions in Tanzania.
