KLIMOVA, Katerina et al. Octreotide long-active release in the treatment of gastrointestinal bleeding due to vascular malformations: cost-effectiveness study. Rev. esp. enferm. dig. [online]. 2015, vol.107, n.2, pp.79-88. ISSN 1130-0108.

Introduction: Gastrointestinal hemorrhage due to vascular malformations has a negative impact on patients' quality of life and consumes an important quantity of resources. Objective: Analyze the cost-effectiveness of long-active releasing octreotide (OCT-LAR) in the treatment of gastrointestinal haemorrhage secondary to vascular malformations. Material and methods: Retrospective study, including 19 pacients that were treated with mensual injections of OCT-LAR between 2008-2013. The number of blood transfusions, hemoglobin levels, hospital admissions and possible side effects during the year before treatment and the year after the start of the treatment were assessed, and cost-effectiveness was analyzed. Results: After the beginning of the treatment with OCT-LAR, complete response was observed in 7 patients (36.8 %), partial response in 7 patients (36.8 %) and 5 patients (26.3 %) continued to require admissions, blood transfusions and/or endoscopic treatment. We observed significant reduction in the length of admission per year (in days) before and after the start of the treatment (22.79 versus 2.01 days, p < 0.0001) as well as in the number of blood transfusions administered (11.19 versus 2.55 blood transfusions per year, p = 0.002). The mean haemoglobin levels increased from 6.9 g/dl to 10.62 g/dl (p < 0.0001). We observed reduction of costs of 61.5 % between the two periods (from 36,072.35 € to 13,867.57 € per patient and year, p = 0.01). No side effects related to treatment were described. Conclusion: In conclusion, OCT-LAR seems to be a cost-efficient and safe pharmacological treatment of gastrointestinal haemorrhage secondary to vascular malformations, mainly in patients in whom endoscopic or surgical treatment is contraindicated.
