ABSTRACT
Purpose or Objective RTQA practice is known to have significant variation amongst institutions worldwide. It is critical to maintaining patient safety, treatment effectiveness and accuracy. However there is no standard practice, with often only target volume delineation reviewed alone and performed retrospectively. Previous studies have highlighted higher rates of changes made in more complex techniques and subsites. This study aims at evaluating our prospective structured peer review process in a proton beam therapy (PBT) centre. Materials and Methods We reviewed the RTQA cases of all patients treated at The Christie Proton Beam Centre since its opening in November 2018 until February 2021. The RTQA process is carried out weekly, is subsite specific and every case has their target volumes and plans reviewed in detail in the presence of consultants, fellows, physicists and dosimetrists. Since the COVID-19 pandemic, the peer review meetings are now virtual. Every peer review has a standardised RTQA form filled. We classified the peer reviews as having major/minor or no change. A major change was one where the target volumes (GTV and/or CTV) were too small or big;dose fractionation was incorrect to that of the prescription treated and any plan that was changed. A minor change was one where there were minor modifications to the target volumes, OARs or non-essential suggestions in relation to the plan that didn’t result in the plan being altered eg. addition of an OAR. Results There was a total of 1,209 peer reviews for 462 patients. 100% of cases had both volumes and plans peer reviewed prospectively. 591 were reviews of target volumes and 618 were plan reviews. In total there were 208 (17%) major changes, 194 (16%) minor and 807 (67%) with no changes. Of the major changes 137 (66%) were target volumes and 71 (34%) plans. Of the minor changes 174 (90%) were target volumes and 20 (10%) plans. There were more major and minor changes in the brain and head & neck subsites possibly due to their complexity. When diagnoses in the brain were categorised (Table 1) and reviewed against changes using a chi-squared test the resulting p-value = 0.027 suggests a significant relationship between type of diagnoses and likely need for change following peer review.(Table Presented) Conclusion Target volume delineation and radiotherapy plans particularly in brain, head & neck as well as other complex subsites require mandatory prospective review as highlighted above. We have shown this to be practically achievable and successful despite challenging times
ABSTRACT
Introduction Innovative models of service delivery are required to provide Comprehensive Geriatric Assessment for older patients presenting to the Emergency Department with frailty syndromes. Method In 2018, the Older Person’s Assessment Service began a liaison service to the ED, taking referrals from the medical and ED teams for patients who presented with frailty syndromes (falls, cognitive impairment, care dependence, polypharmacy). The service saw 437 patients April–August 2018. 76% of the patients assessed were discharged by utilising available community services, rapid access outpatient follow up and inpatient reablement off the acute site. The service was estimated to avoid 50–80 admissions per month to medicine (saving 17–23 beds a year) and was commissioned as a permanent service. Phase 2 In 2020, a dedicated unit within ED was allocated to OPAS, enabling the acceptance of patients directly from triage and from the Ambulance Service by direct referral. This provided rapid access to specialist assessment, continued access to Elderly Care services, avoided exposure to coronavirus related admissions and the risks of nosocomial infection associated with admission. The service operates from 8 am-4 pm on weekdays. Results Between June 2020 and October 2021, the service saw 1,173 new patients. 988 patients (84.5%) were discharged off the acute site on the day of assessment. 68 (5.79%) patients were admitted to other facilities run by the Health Board (e.g Inpatient Reablement). The average age of an OPAS patient was 83 yrs and had a CFS > 5. Readmission rate at 14 days was 4% (47).Of the 253 patients who were admitted to an inpatient setting, 13.5% (35) contracted nosocomial covid-19. Conclusion The service has been supported and funded to expand into extended weekday hours as a result of this success and there are plans for future 7 day working.
