Adherence to antiemetic guidelines andcontrol of chemotherapy-induced nauseaand vomiting (CINV) in a large hospital

摘要

Purpose: The aim of the study was to determine the antiemetic prescription adherence both to the protocol of our hospital and to international recommendations, as well as to analyze the relationship between this adherence and the incidence of nausea and vomiting (NV) and between the adherence and patients' individual risk. Methods: This is a four-month observational study which included antiemetic prescriptions for adult cancer patients. Prescriptions were considered adherent or not to hospital protocol and also to international guidelines. Patients were given a form to record the NV they suffered and this was to be returned at their next appointment. Results: A total of 102 prescriptions were analyzed. Taking into account the hospital protocol, 59% and 54% were correct (acute and delayed phase, respectively). Of those considered outside the protocol, 24% and 13% did follow international guidelines. In the delayed phase, complete response was achieved in 76% and 72% of the patients, with compliant and non-compliant prescriptions, respectively (82% and 90% in the acute phase). Adherence to the hospital protocol was higher in patients under 50 years old (p = 0.015) and in those without previous experience of NV (p = 0.010). Adherence to international guidelines was higher in female patients (p = 0.023). Conclusion: Our study confirms low adherence with both local and international recommendations for antiemetic prescriptions. However, we could not prove that adherence involves a CINV reduction. Adherence did not seem to be influenced by the doctor's perception of the patient's risk of emesis.
