• W1995847631 abstract "Expanding metal oesophageal stents are being used more commonly to palliate patients with inoperable oesophageal carcinoma. Many reports have so far documented their clinical effectiveness, however, their high acquisition cost has caused on-going concern when compared with the cost of conventional therapies. We reviewed 64 consecutive patients with inoperable oesophageal carcinoma, half of whom had received our conventional method of palliation using a variety of techniques including, BICAP diathermy, alcohol injection and Atkinson tube insertion. The other half (32 patients) were treated with expandable metal stents -- Gianturco Z stents (Cook UK Ltd) and uncovered Ultraflex stents (Microvasive, Boston Scientific). The physical amount of resources consumed were identified and measured (number of diagnostic and support procedures, days as in patients, number of day cases or outpatient attending) and an average NHS cost was applied to this resource use. All costs were summated over the period of palliation from the date of the first intervention with palliative intent until death. Although the patients in this study were not randomized, the two groups were matched to ensure comparability in clinical manifestation (uncomplicated biopsy proven oesophageal carcinoma) and the average age of patients from each group. A difference was identified between the length of survival in both patient groups and the analysis was corrected for this by estimating a cost per day of palliative support. Patients palliated with metal stents underwent fewer procedures and spent fewer days in hospital during the time period from presentation until death even when corrected for differences in survival. Patient outcome (effectiveness of palliation) was measured by recording mean dysphagia scores which were recorded before and after palliation. Metal stents were found to lead to a significantly higher improvement in dysphagia in comparison to conventional therapy. In addition, the mortality related to metal oesophageal stents was lower than Atkinson tube insertion. The average cost of palliation was much lower in the metal stent group (mean = pound sterling 2817) compared with the cost in those palliated conventionally (mean = pound sterling 4566). However, once this was corrected for survival the difference in the cost of palliation on a per diem basis was reduced (metal stents = pound sterling 60 per day, conventional group = pound sterling 72 per day). The results of our study indicate that the initial high cost of metal stents is more than outweighed by resource savings elsewhere in the hospital by virtue of reduced need for re-intervention and shorter length of hospital in patient stay. Such cost savings taken in combination with the improved clinical effectiveness and low mortality related to metal stents provide significant support for introducing their use into clinical practice." @default.
