PURPOSE Peer review of radiation treatment (RT) plans is a key component of quality assurance programs in radiation medicine. A 2011 current state assessment identified considerable variation in the percentage of RT plans peer reviewed across Ontarios 14 cancer centers.In response, Cancer Care Ontario launched an initiative to increase peer review of plans for patients receiving radical intent RT. METHODS The initiative was designed consistent with the Kotter eight-step process for organizational transformation. A multidisciplinary team conducted site visits to promote and guide peer review and to develop education and implementation processes in collaboration with the centers. A centralized reporting infrastructure enabled the monitoring of the percentage of RT courses peer reviewed and the timing of peer review (before completion of 25%of treatment visits, after completion of >25%treatment visits). RESULTS The initiative is ongoing, but early results indicate that the proportion of radical intent RT courses peer reviewed province wide increased from 43.5% (April 2013) to 68.0%(March 2015). This proportion is now a quality metric in Ontario and is publicly reported through the Cancer System Quality Index. The performance target for this metric was initially set at 50%(cases treated with radical intent) and revised to 60% in 2014. Provincial performance exceeded targets in both years (58.2% and 68.2%, respectively). Considerable variation was observed, however, in rates and timing of peer review among Cancer Care Ontario centers. CONCLUSION This initiative demonstrates that a change management framework can be useful for planning and achieving substantial increases in jurisdictional peer review activities.

INTRODUCTION Despite increasing chemoradiotherapy treatment, there is a paucity of information regarding the effects of radiation exposure on ambulatory infusion pumps used to deliver chemotherapy or other essential medications. The aim of this overview is to present the available evidence on this subject, heighten awareness within the clinical community, provide considerations for minimizing possible negative effects on patient care, and encourage the monitoring of infusion devices after exposure to radiation or electromagnetic interference. METHODS Published literature was systematically searched using MEDLINE and EMBASE; gray literature was searched using Google and an environmental scan of relevant Web sites. A multidisciplinary working group reviewed the compiled evidence, and a draft of the document was sent to health professionals from various disciplines for an external review. RESULTS Four reports and three manufacturer device alerts were identified that suggest a risk of pump malfunction as a result of radiation exposure. The estimated cumulative dose at which pump failure has been reported ranges from 28.5 to 42 Gy; however, additional clinical investigations should be undertaken. Pump relocation, pump shielding, and assessment of the pump after radiation exposure are most commonly suggested to minimize pump malfunction related to radiation exposure. A list of additional considerations is offered for those developing institution specific policies and procedures based on the available evidence and expert consensus. CONCLUSION The varied and unpredictable results of radiation exposure on infusion devices suggest that additional testing should be carried out to determine the limits of dose exposure and to raise awareness around this patient safety issue.

PURPOSE To describe the outcomes of peer review across all 14 cancer centers in Ontario. METHODS AND MATERIALS We identified all peer-reviewed, curative treatment plans delivered in Ontario within a 3-month study period from 2013 to 2014 using a provincial cancer treatment database and collected additional data on the peer-review outcomes. RESULTS Considerable variation was found in the proportion of peer-reviewed plans across the centers (average 70.2%, range 40.8%-99.2%). During the study period, 5561 curative plans underwent peer review. Of those, 184 plans (3.3%) had changes recommended. Of the 184 plans, the changes were major (defined as requiring repeat planning or having a major effect on planning or clinical outcomes, or both) in 40.2% and minor in 47.8%. For the remaining 12.0%, data were missing. The proportions of recommended changes varied among disease sites (0.0%-7.0%). The disease sites with the most recommended changes to treatment plans after peer review and with the greatest potential for benefit were the esophagus (7.0%), uterus (6.7%), upper limb (6.3%), cervix and lower limb (both 6.0%), head and neck and bilateral lung (both 5.9%), right supraclavicular lymph nodes (5.7%), rectum (5.3%), and spine (5.0%). Although the heart is an organ at risk in left-sided breast treatment plans, the proportions of recommended changes did not significantly differ between the left breast treatment plans (3.0%, 95% confidence interval 2.0%-4.5%) and right breast treatment plans (2.4%, 95% confidence interval 1.5%-3.8%). The recommended changes were more frequently made when peer review occurred before radiation therapy (3.8%) than during treatment (1.4%-2.8%; P=.0048). The proportion of plans with recommended changes was not significantly associated with patient volume (P=.23), peer-review performance (P=.36), or center academic status (P=.75). CONCLUSIONS Peer review of treatment plans directly affects the quality of care by identifying important clinical and planning changes. Provincial strategies are underway to optimize its conduct in radiation oncology.

BACKGROUND Mucosal head and neck squamous cell cancers are often managed with multimodality treatment which can be associated with significant toxicity. The objective of this study was to assess emergency department visits and unplanned hospitalizations for these patients during and immediately after their treatment. METHODS A cohort of patients treated for head and neck squamous cell carcinoma was developed using administrative data. Emergency department visits and hospitalizations in the 90-day post-treatment period was determined. If a second treatment was initiated prior to the completion of 90 days, the attributable risk period was changed to the second treatment. RESULTS Cohort of 3898 patients (1312 larynx/hypopharynx; 2586 oral cavity/oropharynx) from 2008 to 2012. The number of unplanned hospitalizations or ED visits (per 100 patient days) were 0.69 for surgery, 0.78 for surgery followed by concurrent chemoradiotherapy (CCRT), 0.55 for surgery followed by radiotherapy, 0.86 for CCRT, and 0.50 for radiation. Patients receiving CCRT had a statistically higher likelihood of treatment period events. The larynx/hypopharynx cancer subsite, higher comorbidity and more advanced stage of disease were all independent predictors of events. CONCLUSIONS Patients undergoing treatment for head and neck cancer have significant unplanned hospitalizations and visits to the emergency department in the treatment period. Rates are higher in patients receiving CCRT. Quality improvement interventions should be used to improve these rates.

Purpose Communities of practice (CoPs) are defined as groups of people sharing common concerns, problems, or passions about a topic, and who deepen their knowledge and expertise by interacting on an ongoing basis. Cancer Care Ontarios (CCO) Radiation Treatment Program (RTP) has developed multiple CoPs involving staff across 14 regional centres on the basis that knowledge is a critical asset that needs to be managed strategically. This study is to assess the effectiveness of these CoPs on three parameters: knowledge creation, knowledge transfer and exchange (KTE), and community building using the Center for Disease Control and Prevention (CDC) framework for CoP evaluation.

This paper offers best practice recommendations for the maintenance and retention of radiotherapy health records and technical information for cancer programmes. The recommendations are based on a review of the published and grey literature, feedback from key informants from seven countries and expert consensus. Ideally, complete health records should be retained for 5 years beyond the patients lifetime, regardless of where they are created and maintained. Technical information constituting the radiotherapy plan should also be retained beyond the patients lifetime for 5 years, including the primary images, contours of delineated targets and critical organs, dose distributions and other radiotherapy plan objects. There have been increased data storage and access requirements to support modern image-guided radiotherapy. Therefore, the proposed recommendations represent an ideal state of radiotherapy record retention to facilitate ongoing safe and effective care for patients as well as meaningful and informed retrospective research and policy development.

withdrawn 181 PATIENT EXPERIENCE SURVEY OF EARLY-STAGE BREAST CANCER PATIENTS UNDERGOING WHOLE BREAST RADIOTHERAPY Grace Lee, Robert Dinniwell, Anthony Fyles, Tatiana Conrad, Kathy Han, Wilfred Levin, Fei-Fei Liu, Susanne Lofgren, Alexandra Koch-Fitsialos, Gerald Devins, Nora Emad, Bethany Pitcher, Tony Panzarella, Anne Koch Princess Margaret Cancer Centre, Toronto, ON University of Toronto, Toronto, ON Purpose: Adjuvant breast radiotherapy (RT) is a standard treatment option in women with early-stage breast cancer following lumpectomy. Timeliness of RT treatment can impact patient satisfaction. The objectives of this study are to assess: 1) patient satisfaction of their whole breast RT; 2) patient preference for timing of RT start after CT simulation (CTSim); and 3) factors that influence patient stress and quality of life. Methods and Materials: Women undergoing whole breast RT were given a survey before RT treatment and at treatment completion. Patients were offered treatment either through the conventional process (ConvProcess), where RT starts typically within 1-2 weeks of CTSim, or the QuickStart (QS) process, where RT starts one day after CTSim. The pre-treatment (PRE-Tx) survey included questions to understand the social impact of RT, and the post-treatment (POST-Tx) survey included questions relating to social climate and patient satisfaction. Questions relating to RT start preference, stress (Perceived Stress Scale [PSS]) and quality of life (Illness Intrusiveness Ratings Scale [IIRS]), were assessed both at PRE-Tx and POST-Tx. An analysis of covariance was used to determine if the RT process impacted PSS and IIRS, and t-tests were used as a secondary analysis. Fisher’s Exact test was used where appropriate. Results: Ninety-six patients completed the PRE-Tx survey and 88 completed both surveys (QS process n = 28; ConvProcess n = 60). All patients indicated they had a positive experience with the RT

122 Background: The Radiation Treatment Program (RTP) at Cancer Care Ontario (CCO) established several Communities of Practice (CoPs), with the goal of improving radiation treatment (RT) quality and safety. The RTP identifies variation in practice and quality improvement (QI) opportunities in the 14 Regional Cancer Centres (RCCs) and facilitates the development of CoPs to share best practices and standardize care. METHODS Since 2010, the RTP has formed 7 CoPs ( > 185 members in total): 4 intra-disciplinary (Radiation Therapy, Medical Physics, Advanced Practice Radiation Therapy, Radiation Safety) and 3 inter-disciplinary (Head and Neck (HN), Gynecological (GYNE) and Lung Cancer). Members are recruited with the aim of securing engagement from all RCCs to ensure representation of regional diversity and to facilitate adoption of best practices. CoPs are supported with nominal funding and resources provided by CCO, but are led and driven by members, who identify and prioritize key quality issues and select corresponding QI projects to pursue. The RTP performs regular evaluation activities to assess initiative engagement and impact. RESULTS RTP CoPs have enhanced the quality and safety of RT delivery in Ontario through QI initiatives, advice documents and tools that have enabled: Improved RT safety (use of safety straps in RT delivery); Adoption of best practices (RT plan evaluation guidance); Education and knowledge transfer - (stereotactic body RT implementation and training framework); and Support for infrastructure improvements (recommendation for additional Magnetic Resonance-guided brachytherapy units) ( https://www.cancercare.on.ca/ocs/clinicalprogs/radiationtreatment/ ). Advice documents have improved alignment with recommended practice (40% and 50% absolute increases in two HN initiatives). Evaluation surveys indicate that members believe the CoPs have enhanced inter-regional communication and collaboration (89%), knowledge transfer/exchange (91%), and professional networking between RCCs (92%). CONCLUSIONS CoPs can be a highly effective model for improving quality of care. The establishment of CoPs should be considered for QI in other areas of the healthcare system.

120 Background: Radiation treatment (RT) is essential to cancer management, contributing to cure and symptom control. With increasing cancer incidence and treatment complexity, health systems must adapt to ensure patients (pts) receive the highest quality of care. METHODS With the objective of ensuring equitable access to high-quality, safe care, Cancer Care Ontario (CCO), a provincial government agency, identified provincial variability in RT activities. As a result, CCO prioritized 3 quality initiatives over the past 7 years: 1) Access to Intensity Modulated RT (IMRT) (2008-2013); 2) Peer Review of RT plans due to increasing RT planning complexity and the existence of high-profile RT errors (2012-present); and 3) Ensuring equitable access to RT (RT Utilization) (2014-present). Strategic plans were developed using change management framework adapted from the Kotter process for leading change (Kotter, JP. Harvard Bus Rev 73:59-67, 1995). In each initiative, CCO created a climate for change, engaged the provincial RT community to move priorities forward, and worked to sustain achieved gains. RESULTS CCO found that building a project team, communicating a clear understanding of goals and objectives, providing sufficient resources to cancer centres, and public reporting of results were key contributing success factors. IMRT project: Currently in sustainability phase. IMRT rates increased from 20% in 2008/09 - full implementation and target attainment in 2012/13. Public reporting continues. Peer Review of RT plans: Currently moving from engagement to implementation phase. Increase from 44% of RT cases undergoing peer review in 2013/14 to 68% in 2014/15. RT Utilization Project: Currently in engagement phase. Provincial shortfall of 11% in annual RT rates correlates to roughly 2500 pts who do not receive RT as needed. Engaging data experts and consulting with regional administrators, RT utilization is the current change priority for CCOs RT program. CONCLUSIONS These projects demonstrate the possibility of using change management practices to achieve quality improvement in healthcare. Ongoing work continues to ensure that pts in Ontario receive the highest quality cancer care.
