The aim of this study is evaluation of the efficacy of the pharmacist in providing support at the ambulatory therapy center (ATC), especially in connection with chemotherapy side effects in patients. The unsigned questionnaire survey was conducted for patients receiving chemotherapy in ATC. 108 patients were enrolled, and 78 patients answered questions. Patients were asked which kind of specialists provide the most ideal support in the ATC, and what do patients suffer in the ATC. Interestingly, more patients chose pharmacists than nurses and doctors. Many of patients suffer hair loss, nausea and peripheral neuropathy, and many people feel time spent in the ATC is not so meaningful.
