(scores from 1 to 10). RPN numbers were promediated between team members. Failure modes with the higher scores were given the maximum priority to subsequent study to apply specific QA or to take measurements to reduce RPN number. We have identifyed 32 events, the 5 with higher scores were selected in a first stage to reduce risk numbers. Critical steps involved isocenter transfer and integrity between image and treatment system, prescription errors between oncologist prescription and electronic one, and mistakes in treatment delivery . Conclusion Risk analysis in radiotheapy process must be a priority to identify weakness and reduce uncertainty. Multidisciplinary teams help to make flux diagrams, identify critical steps and increase global safety.

Tejedor Gutierrez 1 1 hospital universitario miguel servet, radiotherapy, zaragoza, spain Purpose or Objective To establish a few basic criterias of control of the device, in patients submitted to irradiation, without generating an excessive load of work for the involved services and a There has been created a patient registration sheet, with the clinical information of these and with those parameters relating to the treatment, as well as symptoms suffered by the patient and the information it brings over of the functioning of the device. A protocol of action has been established, so that when a patient of these characteristics is considered to be subsidiary of treatment by ionizing radiation, some procedures are carried out: 1. Consultation to the Service of Cardiology of our center, for the first valuation. 2. Preparation of the treatment , bearing in mind, the distance of the field of irradiation to the device. Make sure that the device does not receive a direct, unshielded irradiation. 3. Schedule of treatment for these patients, making easier the control for the cardiologist of our institution. Once the treatment sessions have finished, the final review is realized and the opportune controls are ruled . Results From the beginning of the project in March 1, 2016, there have been radiated in our department, 16 patients with cardiac implantable devices . - 5 women and 11 men. - The middle ages are 76,8 years (66 years to 86 years). - All of them were non-pacemaker-dependent - The tumour pathology origin of the need of irradiation has been: -The dose of radiation the patients has been variable: between 30 Gy (300cGy/sesión) in case of cerebral metastases, to 69.3 Gy (210 cGy/sesión) in case of the carcinoma of larynx or an extreme hipofraccionamiento in the SBRT of lung, with dose of 60 Gy, in meetings of 1200cGy. In two cases, the patients received concomitant chemotherapy. - The used energies have been, in the majority of the patients, photons of 6, 10 and 15 MV. Only in a case of cancer of breast, the irradiation of photons was followed by 3 meetings electrons. The review of the device, it has not showed alterations of this one in any case. There have been checked the stress to the patient. Material and Methods - Carcinoma of lung 8 patients. -Carcinoma of breast 5 patients. -Brain Metastasis 1patient. -Cancer of rectum patient 1. Cancer of larynx patient 1.

medication, syncopes, IC, as well as all the parameters of the programming of the pacemaker or defibrillator, without some alteration be observing. Conclusion In our patients some alteration has not been targeted in the device after the irradiation, independently of the dose. On balance, RT may be delivered safely in carefully selected patients without the need to remove the PM/ICD from the vicinity of the RT field. EP-1865 The utilization of retrospective registry for patient information of access to care M. Siekkinen 1 , M. Stepanov 2 , A. Hammais 3 , P. Rautava 4 1 Turku University Hospital, Cancer Centre, Turku, Finland 2 Turku University Hospital, Centre for Clinical Inrformatics, Turku, Finland 3 Turku University Hospital, Centre for Clinical Informatics, Turku, Finland 4 University of Turku, Preventive Health Care, Turku, Finland Purpose or Objective Access to care can have a major impact on cancer care outcomes. Therefore hospitals should provide sufficiently rapid access and information of the time to support patients’ decision making of treatment unit. The follow up data of the access to care for patients is also a criterion of qualitative cancer care defined by Organization of European Cancer Institute (OECI). The aim was first to describe how a gynecological (gyn) and breast cancer (bc) patient's access to care during their care pathway has occurred in Turku University Hospital (Tyks) Cancer Centre after receiving an admission note and secondly submit it to the electronic portrayal of patient care pathway for patients. Material and Methods The study was carried out VIII / 2015 - IX / 2016 in clinical information service unit and treatment units in Turku University Hospital (Tyks) in Finland. The target group was gyn (N=1549) and bc (N=945) patients starting their first cancer treatment. The data collection method was a retrospective registry study. The dates of appointments, phone calls, multidisciplinary meetings, treatment decisions and periods (surgery, radiotherapy, chemotherapy, other treatments) were carried out from WebMarela, Oberon and Aria information system entries. Access to care was analyzed from the admission note to the first treatment unit and to other care contact days. The results were analyzed by statistical methods (the mean time and the standard deviation figures). The accuracy of the results was verified by obtaining a review of experts from treatment units. The recommended time of access to cancer care of Ministry of Social Affairs and Health in Finland were taken into consideration. Results were presented quarterly and linked electrically internet sites to the portrayal of patient care pathway for patients. Results In total, access time for gyn patients (n=331) from the first admission note to first treatment unit (gyn surgery outpatient clinic) contact (first appointment) was 11 days (mean; quarterly range 10-12) and to surgery 28 days (mean; quarterly range 24-35) or to radiotherapy/chemotherapy 41 days (mean, quarterly range 39-43). Access time for bc patients (n=661) from the first admission note to first treatment unit (breast surgery outpatient clinic) contact (phone call) was 4 days (mean, quarterly range 2-5), to appointment 14 days (mean; quarterly range 10-15) and to surgery 27 days (mean; quarterly range 21-33) or to radiotherapy/chemotherapy 20 days (mean; n=1). Guarterly, access to care for gyn patients was highest at second quarter 2015 and 2016, and for bc patients increased linearly from first quarter 2015 to third quarter 2016. The increase was not depend on number of patients.
