Objective The aim of the study was to compare the health outcomes and resource use of cancer patients who were new persistent opioid users with those who were not, after undergoing curative intent surgery for cancer. Background Little is known about long-term health outcomes (overdose, mortality) and resource utilization of new persistent opioid users among cancer patients undergoing curative-intent surgery. Methods This retrospective cohort study included all adults with a diagnosis of solid cancers who underwent curative-intent surgery during the study period (2011-2015) in Alberta, Canada and were opioid-naive before surgery, with a follow-up period until December 31, 2019. The key exposure, 'new persistent opioid user', was defined as a patient who was opioid-naive before surgery and subsequently filled at least one opioid prescription between 60 and 180 days after surgery. The primary outcome was opioid overdose that occurred within 3 years of surgery. All-cause death, non-cancer caused death, and department visit (yes vs. no), and hospitalization (yes vs. no) in the follow-up periods were also included as outcomes. Results In total, 19,219 patients underwent curative intent surgery with a median follow-up of 47 months, of which 1,530 (8.0%) were identified as postoperative new persistent opioid users. In total, 101 (0.5%) patients experienced opioid overdose within 3 years of surgery. Compared with non-opioid users, new persistent opioid users experienced a higher rate of opioid overdose (OR=2.37, 95% CI: 1.44 - 3.9) within 3 years of surgery. New persistent opioid use was also associated with a greater likelihood of being hospitalized (OR=2.03, 95% CI: 1.76-2.33) and visiting an emergency room (OR=1.83, 95% CI: 1.62-2.06) in the first year after surgery, and a higher overall (HR=1.28, 95% CI: 1.1-1.49) and non-cancer caused mortality (HR=1.33, 95% CI: 1.12-1.58), when compared with non-opioid users. Conclusion Post-operative new persistent opioid use among cancer patients undergoing curative-intent surgery is associated with subsequent opioid overdose, worse survival and more health resource utilization.

There are limited data on patient-reported outcomes near the end of life in patients with gynaecologic cancers. This study aimed to assess the symptom burden in the last 6 months of life in a real-world cohort.Patients diagnosed with metastatic gynaecologic malignancies from 2016 to 2019 who completed the revised Edmonton Symptom Assessment System (ESASr) questionnaire within 6 months of death in a large Canadian province were identified. Patient-reported symptom scores were categorized as none to mild (0-3) and moderate to severe (4-10). Individual symptoms were subsequently grouped into physical, psychological, and total subscores. The severity of symptoms was further analyzed for any associations with age, time to death, and primary tumour site (ovarian vs. uterocervical and vulvovaginal).We identified 107 patients with gynaecologic malignancies including 59 ovarian, 29 uterocervical, and 19 vulvovaginal cancers. The median ages at diagnosis and questionnaire completion were 64 and 65 years, respectively. The median time from completing the ESASr questionnaire to death was 65 days. Overall, physical and psychological symptoms were moderate to severe in 57.9% and 40.2% of patients, respectively. Among the individual symptoms, tiredness was the most commonly reported moderate to severe symptom (74.9%), while shortness of breath was least commonly reported (31.6%). While physical (P0.001) and total symptom (P = 0.009) subscores were more likely to be moderate to severe in intensity as death approached, the psychological subscore (P = 0.744) had no relationship with time to death. Longer time to death was predictive of lower physical (P = 0.002) and total symptom (P = 0.002) subscores, while a primary uterocervical cancer site was associated with a lower psychological symptom subscore (P = 0.042).In the real-world setting, unique symptom trajectories can emerge for patients with gynaecologic cancer near the end of life. Knowledge of these specific symptom patterns can help inform the development and delivery of targeted palliative interventions to improve quality of life for these patients.

Patients dying with cancer can experience various physical and psychological symptoms. We aimed to determine the type and severity of symptoms within the last 6 months of life in a large real-world cohort of patients with cancer. We examined prospectively collected patient-reported outcomes of patients with lung, colorectal, breast, prostate or pancreatic cancer using the revised Edmonton Symptom Assessment System (ESASr) questionnaire from a large province in Canada from 2016 to 2017. The ESASr was categorized into physical and psychological symptom subscores and total symptom score, and each was classified as none to mild (0–3) or moderate to severe (4–10) based on intensity. Multivariable logistic regression analyses were performed to evaluate the relationship between clinical characteristics and symptom scores. We identified 1159 patients eligible for analysis, of whom 52.2% were men and median age was 68 years. There were 613, 192, 149, 111 and 94 patients with lung, colorectal, breast, prostate and pancreatic cancer, respectively. While approximately half of patients reported moderate to severe physical symptom subscores and total symptom scores, only one-third reported moderate to severe psychological subscores. On multivariable logistic regression analyses, women were more likely to report moderate to severe physical (odds ratio [OR], 1.52; 95% confidence interval [CI], 1.08–2.12; P = 0.016), psychological (OR, 1.60; 95% CI, 1.14–2.26; P = 0.006) and total symptom scores (OR, 1.80; 95% CI, 1.28–2.51; P = 0.001). Patients with lung cancer were also more likely to report moderate to severe physical and psychological subscores (OR, 1.95; 95% CI, 1.28–2.96; P = 0.002 and OR, 1.78; 95% CI, 1.13–2.81; P = 0.013) and total symptom scores (OR, 1.83; 95% CI, 1.20–2.81; P = 0.005). Finally, those closer to death were more likely to report moderate to severe physical symptom subscores (OR, 2.07; 95% CI, 1.33–3.23; P = 0.001) and total symptom scores (OR, 2.29; 95% CI, 1.46–3.60; P

Serial symptom assessments using patient-reported outcomes may be challenging to implement in routine clinical practices. We aimed to determine if a single measurement of symptom burden at the time of metastatic diagnosis is associated with survival. We examined baseline patient-reported outcomes (within 90 days of diagnosis) of patients newly diagnosed with metastatic breast, lung, colorectal, or prostate cancer using the revised Edmonton Symptom Assessment System (ESASr) questionnaire. The ESASr was categorized into physical, psychological, and total symptom domains whereby scores were classified as none to mild (0–3) or moderate to severe (4–10). Multivariable Cox proportional hazards models were constructed to evaluate the effect of baseline symptom scores on overall survival. We identified 1316 patients eligible for analysis. There were 181, 601, 240, and 294 patients with breast, lung, colorectal, and prostate cancer, respectively. Approximately one-quarter of all patients reported moderate to severe physical, psychological, and total symptom subscores. On multivariable Cox regression analysis, older age (P

OBJECTIVE This study aimed to evaluate the association between prescribers' opioid prescribing history and persistent postoperative opioid use in cancer patients undergoing curative-intent surgery. BACKGROUND Study has shown that patients may be over-prescribed analgesics after surgery. However, whether and how the prescriber's opioid prescribing behavior impacts persistent opioid use is unclear. METHODS All adults with a diagnosis of solid cancers who underwent surgery during the study period (2009-2015) in Alberta, Canada and were opioid-naive were included. The key exposure was the historical opioid-prescribing pattern of a patient's most responsible prescriber. The primary outcome was "new persistent postoperative opioid user," was defined as a patient who was opioid-naive before surgery and subsequently filled at least 1 opioid prescription between 60 and 180 days after surgery. RESULTS We identified 24,500 patients. Of these, 2106 (8.6%) patients became a new persistent opioid user after surgery. Multivariate analysis demonstrated that patients with most responsible prescribers that historically prescribed higher daily doses of opioids (≥50 vs

Patient-reported outcomes (PROs) are used to assess patients’ symptoms and supportive care needs. While PROs are increasingly employed in clinical practice, research utilizing these data remains limited. Our goal was to evaluate PROs from a provincial cancer program. A retrospective, population-based cohort study using administrative health data of patients in Alberta, Canada, diagnosed with cancer between January 1, 2016, and October 23, 2017. Adults who completed PROs (Edmonton Symptom Assessment System, ESAS) and supportive care needs inventory (Canadian Problem Checklist)) within ± 60 days of diagnosis were included. Patients were stratified by tumor types (breast, colorectal, lung, prostate, hematological, or other). Descriptive statistics were used to characterize symptom burden and supportive care needs. Multivariate logistic regression was used to evaluate factors associated with higher symptom severity. We included 1310 patients (mean age 64 years; 51% female), the majority of whom had breast (19%), lung (25%), or other cancers (26%). For the cohort, severity of symptoms based on ESAS was low, but prevalence of specific symptoms was high including tiredness (84%), anxiety (60%), pain (60%), and low well-being (80%). Seventy percent of the cohort reported at least one supportive care need. The highest-ranking problems were fears and worries and needing information about illness/treatment. There were differences across tumor types with respect to symptoms and supportive care needs. Comorbidity and having a high number of supportive care needs were associated with higher symptom severity. Our results underscore the need to develop and implement tumor-specific supportive care interventions.

Objective Self-management has been proposed as a strategy to help cancer patients optimize their health and well-being during survivorship. Previous reviews have shown variable effects of self-management on outcomes. The theoretical basis and psychoeducational components of these interventions have not been evaluated in detail. We aimed to evaluate the evidence for self-management and provide a description of the components of these interventions. Methods We conducted a systematic review of self-management interventions for adults who had completed primary cancer treatment by searching MEDLINE, EMBASE, PsychINFO, CINAHL, Scopus, Cochrane Database of Systematic Reviews, National Institutes of Health Clinical Trials Registry, and Cochrane CENTRAL Registry of Controlled Trials. We included experimental and quasiexperimental designs. Data synthesis included narrative and tabular summary of results; heterogeneity of interventions and outcomes precluded meta-analysis. Study quality was evaluated using the Cochrane risk of bias tool or the risk of bias of nonrandomized studies tool. Results Forty-one studies published between 1994 and 29 March 2018 were included. Studies were predominantly randomized controlled trials and targeted to breast cancer survivors. A variety of intervention designs, psychoeducational components, and outcomes were identified. Less than 50% of the studies included a theoretical framework. There was variability of effects across most outcomes. Risk of bias could not be fully assessed. Conclusions There are limitations in the design and research on self-management interventions for cancer survivors that hinder their translation into clinical practice. Further research is needed to understand if these interventions are an important type of support for cancer survivors.

The collection of patient reported outcomes (pros) is a standard of care in many cancer organizations. In Alberta, pros have been integrated into routine clinical practice since 2012. This longitudinal collection of pros provides a wealth of data and a unique research opportunity to improve cancer care. The goal of this pro data initiative is to establish a robust repository of information for ongoing clinical care and research focused on pros. In this paper, we describe the rationale, scope, and design of this initiative. The initiative consists of pros and other administrative health data from the province of Alberta. Retrieval of health data from a variety of provincially governed sources will create a platform of information on pros, health outcomes, cancer data, other health conditions, and demographics. The aims of the initiative are to use the data to inform best practices at the point of care, to conduct health services research, particularly clinical epidemiology studies, and to evaluate a variety of pro-related outcomes. Because this effort represents our first to integrate routinely collected pros with other administrative health data, a unique and robust data repository will be created. The ability to integrate various types of data will provide a comprehensive mechanism to evaluate a variety of outcomes. Because cancer care in Alberta is governed by a single health care system, the data linkages will include population health and psychosocial cancer data. We anticipate that research related to this initiative will ultimately help to inform more patient-centred care.

OBJECTIVES Managing one's health after colorectal cancer may present specific challenges given long-term impacts to biopsychosocial functioning. Understanding experiences of managing one's health post-treatment is important to informing patient-centred supportive care. METHODS A qualitative study with 19 patients who had completed treatment for colorectal cancer to explore the experience of managing one's health. Following Thorne's Interpretive Description, we conducted interviews using either focus groups or individual interviews. Transcribed data were analysed following Thorne's approach. Sociodemographic and clinical characteristics were also collected. RESULTS The metaphor of living with paradox was the main theme characterising the experiences of managing one's health in the post-treatment period. Participants described the ambiguity of health, their need to accept the new normal, losing control and taking back control, experiencing positive and negative life changes, and the need to continually reframe their perspectives to focus on the positives. CONCLUSION Our findings suggest that providing patient-centred care to colorectal cancer survivors post-treatment involves recognising their changing and sometimes conflicting experiences. Their ability to manage their health may fluctuate and their supportive care needs may not fit with a particular trajectory. Cancer care systems should strive for flexibility in the structure and timing of support available.

To examine the prevalence of comorbidities and the association of these comorbidities with demographics, tumor characteristics, treatments received, overall survival, and causes of death in a population-based cohort of colorectal cancer (CRC) patients. Adult patients with stage I–III CRC diagnosed between 2004 and 2015 were included. Comorbidities were captured using Charlson comorbidity index. Causes of death were categorized using International Classification of Diseases, tenth revision codes. Patients were categorized into five mutually exclusive comorbid groups (cardiovascular disease alone, diabetes alone, cardiovascular disease plus diabetes, other comorbidities, or no comorbidities). Data were analyzed using descriptive statistics, Kaplan-Meier survival analyses, and Cox proportional hazards models. There were 12,265 patients. Mean follow-up was 3.8 years. Approximately one third of patients had a least one comorbidity, with cardiovascular disease and diabetes being most common. There were statistically significant differences across comorbid groups on treatments received and overall survival. Those with comorbidity had lower odds of treatment and greater risk of death than those with no comorbidity. Those with cardiovascular disease plus diabetes fared the worst for prognosis (median overall survival 3.3 [2.8–3.7] years; adjusted HR for death, 2.27, 95% CI 2.0–2.6, p

Background Family caregivers to cancer patients are at risk for physical and psychological morbidity as a direct result of being in the caregiver role. Exercise as an intervention to support caregiver health and well-being has been tested in other caregiver populations; however, no randomized controlled trials testing the effects of an aerobic and resistance training program have been conducted where cancer caregivers only have participated. Purpose To examine the effects of a 12-week exercise program on quality of life (Short Form 36 v2), psychological outcomes, physical activity levels, and physical fitness in caregivers to cancer patients. Methods Seventy-seven caregivers were randomized to either an exercise intervention or wait-list control. Two participants in the exercise arm dropped out immediately after their baseline assessment. Outcome data for n = 77 participants were analyzed using intention-to-treat analysis with linear mixed models. Results Significant group by time interaction effects were detected for exercise on the mental health component score of quality of life, self-reported weekly exercise levels, and the six-minute walk test. Small to medium effect sizes were detected on several outcomes including physical health component of quality of life (d = 0.36), mental health component of quality of life (d = 0.74), depression (d = 0.41), anxiety (d = 0.35), physical activity levels (d = 0.80), and the six-minute walk test (d = 0.21). Conclusions The findings suggest that exercise may improve health and well-being and could be considered as an additional type of support offered to cancer caregivers. Clinical trial registration no NCT02580461.

162 Background: Young women with breast cancer (YWBC) have unique survivorship needs due to life stage at point of diagnosis. Peer support sought by YWBC through social media channels appears to be rising. We aimed to understand the unmet needs of YWBC in order to develop a tailored peer support program to improve young women’s breast cancer experience and ultimately reduce psychosocial morbidity long-term. Methods: Using qualitative inquiry, we conducted semi-structured interviews with YWBC survivors and clinicians using purposive sampling. Inclusion criteria were women aged 40 years or younger at diagnosis, stage 0-IV disease. Survivors were minimum one year post-diagnosis and with active treatment complete. Interviews were recorded and transcribed verbatim and data was analyzed using Thorne’s Interpretive Description. Themes were reviewed with study team throughout data analysis. Results: Thirty-six participants were interviewed from ten centers across seven Canadian provinces; mean age 36 years. Participant reported demographics:18% ‘visible minority’, 9% ‘born outside Canada’, 7% ‘Indigenous’ and 54% of patients’ household income at or below Canadian average. At point of diagnosis 69% married, 44% had children and 9% pregnant or postpartum. Themes from YWBC interviewed focused on coping needs: feeling alone, misunderstood by professionals and misplaced among peers. Participants described all-age peer support groups risked triggering anxieties, lacked convenience and were comprised of women at later life stages with differing needs. YWBC reported lack of young age breast cancer-specific peer support. YWBC frequently found support through social media de novo, by following young-age breast cancer survivor pages, blogs and forums as well as virtual support groups. YWBC also report benefit from identifying similar life and cancer stage survivors globally and forming individual relations virtually, through direct messaging. Additionally, benefits described from age-specific social media support included unique shared experience and understanding, hope from positive outcomes of similar life stage diagnoses, and increased confidence and healthcare navigation for YWBC. Women unanimously requested one on one peer support program development - a survivor mentorship scheme specifically for YWBC that would provide the convenience of online support without the obligations or emotionally overwhelming nature of structured support groups. Conclusions: We have identified unique support needs from this young cohort of women that are not currently being met within standard Canadian healthcare pathways. We aim to develop a novel one on one peer support program for YWBC, to optimize psychosocial support and improve young women’s empowerment and autonomy in managing the effects of cancer long-term.

Purpose/objectives To document self-reported physical health and activity levels of older caregivers. Gender differences in physical health, physical activity levels, and predictors of physical activity were also examined. . Design A cross-sectional study. . Setting Tom Baker Cancer Centre in Calgary, Alberta, Canada. . Sample 130 caregivers aged 60 years or older caring for individuals with breast, prostate, or colorectal cancer. . Methods Self-report survey including validated questionnaires on physical and mental health and physical activity levels. Convenience sampling was used. Data were analyzed using descriptive statistics, correlations, and multiple regression. . Main research variables The physical component score of the SF-36v2® was the main research variable. Other variables included the mental component score of the SF-36v2, sleep quality, depression, social support, physical activity levels, and anxiety. . Findings The mean age of caregivers was 70 years. Physical health and physical activity levels were higher than population norms. A significant difference in physical health (p = 0.015) existed between men and women but not in physical activity levels (p = 0.079). Predictors of physical activity levels were age (β = -0.291), physical health (β = 0.307), and caregiving hours per week (β = -0.221). . Conclusions The findings suggest that gender had a minimal effect on physical health and no effect on physical activity levels in older caregivers. Depression and poor sleep quality were high in some caregivers but did not predict physical activity levels. . Implications for nursing The negative effects of caregiving on physical health and physical activity levels in older caregivers are not universal. Nurses should be aware of the caregiving situation and promote health based on the individual.

Background:Family caregivers are an important health care resource and represent a significant proportion of Canadian and US populations. Family caregivers suffer physical and psychological health problems because of being in the caregiver role. Interventions to support caregiver health, including physical activity (PA), are slow to be investigated and translated into practice.Purpose:To examine the evidence for PA interventions in caregivers and determine factors hampering the uptake of this evidence into practice.Methods:A systematic review and evaluation of internal and external validity using the RE-AIM (Reach, Efficacy/Effectiveness, Adoption, Implementation, and Maintenance) framework was conducted. Randomized controlled trials or pretest/posttest studies of PA interventions were included.Results:Fourteen studies were published between 1997 and 2015. Methodological quality of studies and risk of bias was variable. External validity criteria were often not reported. Mean reporting levels were 1) reach, 53%; 2) efficacy/effectiveness, 73%; 3) adoption, 18%; 4) implementation, 48%; and 5) maintenance, 2%.Conclusions:The lack of reporting of components of internal and external validity hinders the integration of caregiver PA interventions into clinical or community settings. Researchers should focus on standardized outcomes, accepted reporting criteria, and balancing factors of internal and external validity, to advance the state of the science.

Concerns around chronic opioid use (COU), misuse, and harms have led to increased scrutiny of opioid prescribing in oncology. There is lack of research examining patient-level factors associated with COU. Our aim was to examine patient-level factors associated with COU in newly diagnosed cancer patients. Population-based retrospective cohort study using administrative health data of patients in Alberta, Canada, diagnosed between February 2016 and October 2017. Adult cancer patients who completed a symptom survey within ± 60 days of diagnosis were included. Patients were divided into two groups: COU (defined as continuous opioid prescriptions for at least 90 days post-diagnosis) and non-chronic opioid use (NCOU). Logistic regression was used to evaluate factors associated with COU. We included 694 patients (mean age 65 years; 51% female). Most had breast (20%), colorectal (13%), and lung (33%) cancers. Of the 14% with COU, 79% were opioid naive at diagnosis. Those in the COU group were more often diagnosed with advanced cancer (66% versus 40%), had lung cancer (47%), and were opioid tolerant (> 90 days of continuous opioids within one-year pre-diagnosis). A total of 64% of COU versus 27% of NCOU had moderate to severe pain at diagnosis (p

Importance The results from the recent International Duration Evaluation of Adjuvant Therapy (IDEA) collaboration have led some clinicians to adopt shorter durations of adjuvant chemotherapy for patients with stage III colon cancer. The extent to which these findings are supported by other data is unknown. Objective To conduct a systematic review and meta-analysis of randomized and observational studies investigating the association between the duration of adjuvant chemotherapy and survival among individuals diagnosed as having stage II and III colon cancer (PROSPERO protocol CRD42018108711]). Data Sources Abstracts published in English between 2003 and 2018 within the MEDLINE, Embase, CENTRAL, and CINAHL databases were reviewed by 2 authors. Also searched were conference proceedings and the indexes of high-impact oncology journals. Study Selection Studies were excluded if they did not present original data; focused on animal populations, on cancers in sites other than the colon, or on patients with stage 0, I, or IV disease; did not examine a 5-flourouracil–based monotherapy or combination therapy; or did not evaluate the association between treatment duration and survival. The search identified 2341 articles, from which 2 randomized trials and 20 observational studies were included in the meta-analysis. Data Extraction and Synthesis This study followed the PRISMA and MOOSE reporting guidelines. The risk of bias was assessed by 2 authors using the Cochrane and Risk of Bias in Nonrandomized Studies of Interventions (ROBINS-I) tools. The results were synthesized using a random-effects model. Main Outcomes and Measures The primary and secondary outcomes were overall survival and disease-free survival, respectively. It was hypothesized a priori that 3 months of chemotherapy would be as effective as 6 months of chemotherapy. Results Twenty-two studies were included in the meta-analysis, representing 43 671 patients. The inclusion of patients with stage II disease or with rectal cancer was identified as a source of heterogeneity. After restricting the analysis to patients with stage III colon cancer, there was no association between the duration of chemotherapy and overall survival among studies involving FOLFOX (leucovorin calcium [folinic acid], fluorouracil, and oxaliplatin) or CAPOX (capecitabine plus oxaliplatin) regimens (hazard ratio [HR], 0.80; 95% CI, 0.58-1.09). Among studies focused exclusively on monotherapy, the standard 6-month regimen relative to a 3-month regimen was associated with improved survival (HR, 0.59; 95% CI, 0.52-0.68). Conclusions and Relevance Shortened durations of chemotherapy may reduce survival among patients with stage III colon cancer prescribed monotherapy but not a combination regimen.

Background Family caregivers (FCs) to cancer patients are at increased risk for physical and emotional health problems as a result of being in the caregiver role. Current research on interventions for FCs has focused on psychological support or educational interventions, with very little investigation of exercise in maintaining or improving health. Based on our preliminary survey, participation in regular exercise to improve health was noted as a priority for FCs. The purpose of the study described in this protocol is to examine the impact of a 12-week structured exercise program on physical functioning (primary outcome), physical activity levels and psychological well-being (secondary outcomes), in FCs caring for adult cancer patients. In addition, the trial described here will examine the outcomes from a 12-week maintenance program, immediately following the initial program. Methods/design A mixed methods design using a randomized control trial (RCT) with a 50/50 allocation ratio for the quantitative portion, followed by face to face interviews and qualitative data analysis. Approximately 86 participants will be enrolled over a 10 month period. The intervention will consist of a structured exercise program of aerobic and resistance training. An intention to treat principle using mixed effects modeling will guide data analysis. Discussion FCs will continue to play a pivotal role in the care of cancer patients as the incidence and chronicity of cancer increases. The research described in this protocol will provide information about the impact of an exercise program in supporting FC health. Trial registration ClinicalTrials.gov Identifier: NCT02580461

Background Self-management interventions have been proposed as effective strategies to improve health and well-being and promote optimal coping in cancer survivors. Several reviews have shown benefits of self-management interventions on a variety of patient-reported outcomes. Effective self-management strategies in other chronic disease populations are typically based on theories of behavior change, but the extent of theoretical underpinnings in cancer self-management programs has not been evaluated to date. Our aim is to expand on previous reviews by evaluating the effectiveness of self-management interventions in cancer survivors as well as the theoretical components of such interventions. Methods We will conduct a systematic review of self-management interventions for adults who have completed primary treatment for their solid or hematological cancer. Interventions tested using experimental or quasi-experimental methods, with any type of comparator, will be included. A search strategy will be designed with a health sciences librarian and then performed using MEDLINE, EMBASE, PsycINFO, CINAHL, Scopus, the Cochrane database of systematic reviews, the National Institutes of Health clinical trials registry, and the Cochrane CENTRAL registry of controlled trials. Data synthesis will include a narrative and tabular summary of the results. Appropriate statistical analysis may include a meta-analysis using random effects methods to determine the effectiveness of self-management interventions and a meta-regression to evaluate how characteristics of the interventions are associated with the intervention effect. Risk of bias will be evaluated using the Cochrane risk of bias tool or the Risk of Bias in Non-randomized studies tool (RoBANS). Discussion The results of this systematic review will add to previous reviews and expand the existing knowledge base of the effectiveness and active components of self-management interventions for adult cancer survivors.

Introduction Chemotherapy-induced nausea and vomiting (CINV) has been shown to adversely impact patient anxiety, quality of life, treatment adherence, and use of health care resources. CINV control still remains a challenge, and lack of effective communication between the patient and clinician has been highlighted in the literature as the main barrier to optimal control. The Multinational Association of Supportive Care in Cancer (MASCC) has developed a tool (MASCC Antiemesis Tool (MAT)) to improve assessment and subsequent management of CINV by enhancing communication between patients and their clinicians. This study assessed the feasibility of using the MAT in patients at the Tom Baker Cancer Centre. The secondary objective was to describe the incidence of CINV as identified by the tool. Methods and materials This study involved a prospective survey using the MAT in patients receiving intravenous chemotherapy. Subjects completed the MAT twice post-chemotherapy regarding CINV symptoms and returned it at their next clinic appointment. Participants were also surveyed to evaluate feasibility with regard to using the MAT. Results Of the 50 patients recruited, 56% returned surveys. The majority of patients reported that the MAT facilitated communication with their clinician, particularly those who had experienced CINV. Fifty-four percent of patients who returned the MAT reported CINV; however, less than half of them had received American Society of Clinical Oncology-recommended antiemetic regimens. Only four patients with CINV had antiemetic changes made for subsequent cycles. Conclusion The MAT is a feasible tool which can improve communication of CINV symptoms between patients and clinicians, a foundational step toward improving CINV management.

11580 Background: Opioid prescribing in oncology is increasingly scrutinized given public health concerns about chronic opioid use, misuse, and harms. We aimed to evaluate patient reported pain scores, mental health indicators, prior opioid use, and number of opioid prescribers as potential risk factors for chronic opioid use in a large Canadian province. Methods: This was a population-based cohort study using administrative health data of patients in Alberta, Canada, diagnosed between Jan 2016 and Jan 2017, and completed a prospective comprehensive symptom survey within +/- 60 days of diagnosis. Patients were divided into two groups: chronic opioid use (COU) (defined as continuous prescriptions for opioids for at least 90 days post diagnosis) and non-chronic opioid use (NCOU). Logistic regression models were used to evaluate factors associated with COU. Results: We included 694 patients. Most had breast (20%), colorectal (13%), and lung (33%) cancers. There were no differences in mean age (65 years) or gender (50% female) between the groups. In total, 32% had moderate to high pain scores at diagnosis. Of the 14% with COU, 79% were opioid naïve at diagnosis. Those in the COU group were more often diagnosed with advanced stage of disease (66% vs 40%), had lung cancer (47%), and were opioid tolerant at diagnosis (defined as > 90 days of continuous opioids within 1 year prior to their diagnosis) (21% vs 3%). In comparison, 64% of COU versus 27% of NCOU had moderate to severe pain scores at diagnosis (p < 0.001). COU had significantly higher anxiety and depression scores at diagnosis versus NCOU (p = 0.004). Among patients with COU, morphine equivalent daily doses increased from 27.3 (pre-diagnosis) to 65.1 (post-diagnosis). Irrespective of treatment type or stage, those who had moderate to high pain scores, were opioid tolerant at diagnosis, or had multiple prescribers were at greater risk for COU (see Table). Conclusions: Specific patient groups were at increased risk of COU and should be the focus of adaptive prescribing approaches to ensure that opioid use is appropriate. [Table: see text]

6530 Background: Patients with cancer are vulnerable to chronic opioid use. Although opioid use may be appropriate, preliminary data suggest that a significant proportion may be using opioids inappropriately. This study aims to evaluate the association between the history of the providers’ opioid-prescribing patterns and post-surgical opioid use in cancer patients undergoing curative-intent surgery. Methods: This population-based study included all patients diagnosed with common solid tumors who received curative-intent surgery and were non-opioid users prior to surgery between 2009 and 2015 in Alberta, Canada. Based on previously published methods, a new persistent opioid user was defined as opioid-naïve prior to surgery and who subsequently filled at least one opioid prescription between 60 and 180 days after surgery. The opioid-prescribing patterns of a patient’s most responsible provider (MRP) were measured as the mean daily dosage (oral morphine equivalent, OME) that was prescribed to all other patients by that provider prior to the surgical date. Multivariable logistic regression was performed to identify associations between the MRP’s prescribing patterns and the patient’s opioid use after surgery. Results: 14,780 patients met the inclusion criteria and were associated with 2,880 MRPs, among which 2,364 (16%) patients became new persistent opioid users after surgery. Multivariate analysis demonstrated that patients with MRPs who routinely prescribed higher doses of opioids (≥60 vs. 0-59 mg OME: OR = 2.33, P < 0.0001) for their patients were associated with a greater risk of new persistent opioid use after surgery. In addition, those with a higher Charlson comorbidity index (P = 0.006), visited more prescribers (P < 0.0001), had a specific tumor type (breast, colorectal, lung, prostate, melanoma or kidney vs. others, P < 0.0001), received adjuvant chemotherapy (OR = 1.37, P < 0.0001), and received adjuvant radiation (OR = 1.3, P = 0.0004) were also associated with greater risk of new persistent opioid use after surgery. Conclusions: Our results suggest that prescribers with a history of prescribing higher opioid doses are an important predictor of chronic opioid use among cancer patients undergoing curative-intent surgery. Awareness of physician prescribing practices and their unintended consequences may inform strategies to minimize persistent post-operative opioid use in cancer patients.

The Oncology Nursing Society (ONS) has established an ambitious research agenda and professional priorities based on a survey by LoBiondo-Wood et al. (2014). With the overall goal to "improve cancer care and the lives of individuals with cancer" (Moore & Badger, 2014, p. 93) through research activities, translating those research findings to direct clinical practice can be overwhelming. As clinicians, understanding how to critique research for quality prior to incorporating research findings into practice is important. The ultimate goal in this critique is to ensure that decisions made about patient care are based on strong evidence. However, the process for appraisal of qualitative research can be ambiguous and often contradictory as a result of the elusive aspect of quality in qualitative research methods (Seale, 1999). In addition, with more than 100 tools available to evaluate qualitative research studies (Higgins & Green, 2011), a lack of consensus exists on how to critically appraise research findings.

Family caregivers' physical and emotional well-being may be negatively impacted while in the caregiver role. Interventions to support caregiver health have largely focused on psychological support, with only a few studies to date evaluating the role of exercise. Of the exercise studies conducted, there has been one qualitative study examining caregivers' perspectives on the value and impact of this type of intervention. This qualitative study was part of a larger mixed methods investigation including a randomised controlled trial investigating the effects of a 24-week exercise programme for cancer caregivers conducted in western Canada. We aimed to explore cancer family caregivers' experience of participating in a structured exercise programme. We conducted face-to-face interviews with 20 of the participants from the exercise intervention and analysed transcribed data using Thorne's interpretive description as a guiding framework. Two main patterns characterised the experiences of the caregivers. The metaphor of a downward spiral represented the experience of being in the caregiver role, while the metaphor of an upward spiral represented the experience of participating in the exercise programme. Our findings highlight that caregivers valued the exercise programme, experienced positivity through exercise and the group-based format, and noticed improvements to their physical and emotional well-being.

186 Background: Family caregivers (FCs) have negative impacts to their physical and emotional health, and poorer quality of life (QoL) compared to non-caregivers. Most research on FCs has included heterogeneous samples, therefore little is known about specific groups such as older (age 60+) FCs. Older persons are at increased risk for health problems, may have co-morbidities, and be socially isolated. Understanding factors related to QoL may lead to interventions targeted to older FCs. The purpose of this study was to examine factors associated with QoL in older FCs to cancer patients. Methods: The data for this study are from a larger survey of FCs aged 60+, recruited from a hospital-based cancer facility. FCs were included if their care recipient had breast, prostate or colorectal cancer. QoL was measured using the MOSF-36. Analyses using descriptive statistics and Pearson’s correlations were conducted. Results: n = 168 participants consented, with n = 129 surveys returned. The majority of participants were female (60.5 %), 70 yrs old (sd 7.4), had at least a college diploma (65.2 %), were spouses of the patient 92.2%, and retired (60.5%). Mean caregiving hours per week was 24.2 (sd 26.3). Mean time as a caregiver was 31 months (45.9). The majority of patients were on treatment (75.2%) and were 71.3 yrs old (sd 7.5). The Physical Component Summary (PCS) of the MOSF-36 was significantly correlated with gender r = -.24, social support r = .25, sleep quality r = -.47, depression r = -.51, state anxiety r = -.40, and trait anxiety r = -.45 (all p’s < .01). There were significant correlations between the Mental Component Summary (MCS) and social support r = .40, sleep quality r = -.40, depression r = -.77, gender r = -.25, state anxiety r = -.72, and trait anxiety r = -.71 (all p’s < .01). The MCS was correlated with caregiving hours, r = -.197 (p < .05), however, not with patient treatment status. The PCS was not correlated with caregiving hours or patient treatment status. Conclusions: Consistent with previous FC research across different diseases, QoL was associated with gender, caregiving hours per week, social support, sleep quality, depression, and anxiety. Interventions for older FCs of cancer patients could be targeted to specific factors of overall QoL.
