Applying Quality Indicators to Examine Quality of Care During Active Surveillance in Low-Risk Prostate Cancer: A Population-Based Study.

BACKGROUND: Although a few studies have reported wide variations in quality of care in active surveillance (AS), there is a lack of research using validated quality indicators (QIs). The aim of this study was to apply evidence-based QIs to examine the quality of AS care at the population level. METHODS: QIs were measured using a population-based retrospective cohort of patients with low-risk prostate cancer diagnosed between 2002 and 2014. We developed 20 QIs through a modified Delphi approach with clinicians targeting the quality of AS care at the population level. QIs included structure (n=1), process of care (n=13), and outcome indicators (n=6). Abstracted pathology data were linked to cancer registry and administrative databases in Ontario, Canada. A total of 17 of 20 QIs could be applied based on available information in administrative databases. Variations in QI performance were explored according to patient age, year of diagnosis, and physician volume. RESULTS: The cohort included 33,454 men with low-risk prostate cancer, with a median age of 65 years (IQR, 59-71 years) and a median prostate-specific antigen level of 6.2 ng/mL. Compliance varied widely for 10 process QIs (range, 36.6%-100.0%, with 6 [60%] QIs >80%). Initial AS uptake was 36.6% and increased over time. Among outcome indicators, significant variations were observed by patient age group (10-year metastasis-free survival was 95.0% for age 65-74 years and 97.5% in age <55 years) and physician average annual AS volume (10-year metastasis-free survival was 94.5% for physicians with 1-2 patients with AS and 95.8% for those with ≥6 patients with AS annually). CONCLUSIONS: This study establishes a foundation for quality-of-care assessments and monitoring during AS implementation at a population level. Considerable variations appeared with QIs related to process of care by physician volume and Qis related to outcome by patient age group. These findings may represent areas for targeted quality improvement initiatives.

Frailty in Patients With Newly Diagnosed Diffuse Large B-Cell Lymphoma Receiving Curative-Intent Therapy: A Population-Based Study.

BACKGROUND: The objectives of this study were to determine whether frailty is associated with survival in a population-based sample of patients with diffuse large B-cell lymphoma (DLBCL) and to describe the healthcare utilization patterns of frail versus nonfrail patients during treatment. METHODS: A retrospective cohort study was conducted using population-based data in Ontario, Canada. Patients aged ≥66 years diagnosed between 2006 and 2017 with DLBCL or transformed follicular lymphoma who received first-line curative-intent chemoimmunotherapy were included. Frailty was defined using a modified version of a generalizable frailty index developed for use with Ontario administrative data. Cox regression was performed to examine the association between frailty and 1-year mortality. RESULTS: A total of 5,527 patients were included (median age, 75 years [interquartile range, 70-80 years]; 48% female), of whom 2,699 (49%) were classified as frail. Within 1 year of first-line treatment, 32% (n=868) of frail patients had died compared with 20% (n=553) of nonfrail patients (unadjusted hazard ratio, 1.8; 95% CI, 1.6-2.0; P<.0001). Frail patients had higher healthcare utilization during treatment, with most hospitalizations related to infection and/or lymphoma. In multivariable modeling controlling for age, inpatient diagnosis, number of chemoimmunotherapy cycles received, comorbidity burden, and healthcare utilization, frailty remained independently associated with 1-year mortality (adjusted hazard ratio, 1.5; 95% CI, 1.3-1.7; P<.0001). CONCLUSIONS: In a population-based sample of older adult patients with DLBCL receiving front-line curative-intent therapy, half were classified as frail, and their adjusted relative rate of death in the first year after starting treatment was 50% higher than that of nonfrail patients. Frailty seems to be associated with poor treatment tolerance and a higher likelihood of requiring acute hospital-based care.

Care provided by older adult caregivers to a spouse in active cancer treatment: a scoping review.

PURPOSE: Due to population aging, the number of older adults with cancer will double in the next 20 years. There is a gap in research about older adults who are the caregiver of a spouse with cancer. Therefore, this review seeks to answer the overarching research question: What is known about the association of providing care on Health-Related Quality of Life (HRQOL), psychological distress, burden, and positive aspects of caregiving for an older adult caregiver to a spouse with cancer? METHODS: This scoping review was guided by the framework of Arksey and O'Malley and refined by Levac et al. Comprehensive search strategies were conducted in Medline, Excerpta Medica Database (EMBASE), PsycINFO, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) from inception until April 15, 2021. Two independent reviewers screened abstracts, full text, and completed data abstraction. A gray literature search and two stakeholder consultations were conducted. RESULTS: A total of 8132 abstracts were screened, and 17 articles were included. All studies outlined caregivers provided preventive, instrumental, and protective care to a spouse in active cancer treatment. However, the time spent on caregiving was rarely examined (n = 4). Providing care had a negative association on HRQOL, perceived burden, and psychological distress outcomes. Five studies examined positive experiences of caregivers. CONCLUSION: The scoping review findings highlight the informal care provided by older adult caregivers to a spouse with cancer and how the care provided is associated with HRQOL, burden, psychological distress, and the positive aspects of caregiving.

Factors predicting gains in moderate-to-vigorous physical activity in prostate cancer survivors on androgen deprivation therapy.

BACKGROUND: Whether individual, environmental, and psychosocial factors predict changes in moderate-to-vigorous physical activity (MVPA) is poorly addressed in prostate cancer (PC) survivors undergoing androgen deprivation therapy (ADT). PURPOSE: This secondary analysis of a randomized controlled trial examined changes in MVPA following a supervised personal training (PT), supervised group-based (GROUP) program, or a home-based, smartphone-assisted exercise (HOME) intervention in PC survivors on ADT and explored individual, environmental, and psychosocial predictors of MVPA. METHODS: PC survivors on ADT underwent aerobic and resistance training for 6 months via PT, GROUP, or HOME. MVPA was captured via accelerometers and the Godin Leisure-Time Exercise Questionnaire. Changes in MVPA between groups were assessed using linear regression. The following predictors of MVPA were examined using Spearman correlations: the Neighborhood Environment Walkability Scale (NEWS); the Planning, Attitudes, and Behaviours (PAB) scale; the Relatedness to Others in Physical Activity Scale (ROPAS); and individual factors at baseline. RESULTS: Participants (n = 37) were 69.4 ± 6.5 years old and 78.4% were on ADT for ≥ 3 months. Changes in accelerometry-based bouts and MVPA as well as self-reported MVPA did not differ between groups at 6 months. The Aesthetics domain of the NEWS questionnaire at baseline was the strongest predictor of positive MVPA changes (r = .66). Attitude (r = .64), planning (r = .57), and motivation (r = .50) at baseline were also predictive of engaging in higher MVPA throughout the intervention. CONCLUSION: Changes in objective MVPA were modest. Additional emphasis on specific psychosocial and individual factors is important to inform theory-based interventions that can foster PA behavior change in PC survivors on ADT.

Exploring the value of using patient-oriented MRI reports in clinical practice - a pilot study.

PURPOSE: Standard radiology reports (SRR) are designed to communicate information between doctors. With many patients having instantaneous access to SRRs on patient portals, interpretation without guidance from doctors can cause anxiety and panic. In this pilot study, we designed a patient-centred prostate MRI template report (PACERR) to address some of these challenges and tested whether PACERRs improve patient knowledge and experience. MATERIALS AND METHODS: Patients booked for clinical prostate MRI were randomly assigned to SRR or SRR + PACERR. Questionnaires included multiple-choice that targeted 4 domains (understanding, usefulness, next steps, emotional experience) hypothesized to improve with patient-centred reports and short answer questions, testing knowledge regarding MRI results. Clinical encounters were observed and recorded to explore whether adding PACERR improved communication. Likert scaled-responses and short-answer questions were compared using Mann-Whitney U test and Kruskal-Wallis test. RESULTS: Of the 40 participants, the majority were MRI naïve (70%). Patients receiving a PACERR had higher scores in the categories of patient understanding (mean: 4.17 vs. 3.39, p=0.006), usefulness (mean: 4.58 vs. 3.07, p<0.001), and identifying next steps (mean: 1.89 vs. 3.03, p=0.003) but not emotional experience (mean: 4.18 vs. 3.79, p=0.22). PACERR participants found the layout and design more patient friendly (mean: 4.47 vs. 2.61, p<0.001) and easier to understand (mean: 4.37 vs. 2.38, p<0.001). In the knowledge section, overall, the PACERR arm scored better (87% vs. 56%, p=0.004). CONCLUSION: With the addition of prostate MRI PACERR, participants had better understanding of their results and felt more prepared to involve themselves in discussions with their doctor.

The impact of pre-treatment muscle strength and physical performance on treatment modification in older adults with cancer following comprehensive geriatric assessment.

BACKGROUND: Grip strength (GS) and the short physical performance battery (SPPB) have been shown to predict clinical outcomes in older adults with cancer. However, whether pre-treatment GS and SPPB impact treatment decisions following comprehensive geriatric assessment (CGA) is poorly understood. Our objective was to assess the impact of low GS and/or SPPB on treatment modification to initially proposed treatment plans in older adults with cancer following CGA. METHODS: This was a retrospective cohort study of older adults who had undergone CGA before receiving cancer treatment. Data were retrieved from a prospective database in an academic cancer centre and medical records. Treatment modification following CGA was defined as reduced treatment intensity or transition from active treatment to supportive care. Multivariable logistic regression assessed the impact of pre-treatment GS and SPPB on treatment modification following CGA. RESULTS: In total, 515 older adults (mean age: 80.7y) who had undergone CGA prior to cancer treatment were included. Low muscle strength and/or physical performance was observed in 66.4% of participants. Treatment was modified in 49.5% of the cohort following CGA. Low GS and/or SPPB combined was predictive of treatment modification (OR = 1.77, 95%CI = 1.07-2.90, P = 0.025) in multivariable analysis. Additional predictors of treatment modification included palliative treatment intent, comorbidities and malnutrition. CONCLUSIONS: Low GS and/or SPPB combined prior to cancer treatment predicts treatment modification in older adults with cancer and may be useful in treatment decision-making. Management of poor muscle strength and physical performance should be offered to optimize patient care and potentially improve treatment outcomes.

A distance-based, randomized controlled trial for reducing sedentary behavior among prostate cancer survivors: a study protocol.

BACKGROUND: Prostate cancer survivors (PCS) experience long-term side effects beyond treatment such as fatigue, depression and anxiety. Quality and engaging supportive care programs are needed to reduce these chronic and debilitating effects. Independent of physical activity (PA), high volumes of sedentary behavior (SB) are associated with chronic disease-related risk factors and poorer cancer-specific quality of life (QoL). Simultaneously increasing PA and decreasing SB may be an effective health promotion strategy. Given that PCS may face several barriers to engaging in supervised programs, there is a need to develop and assess the efficacy of interventions that employ distance-based approaches for behavior change. The primary aim of this study is to determine the effects of a 12-week intervention (Fitbit + behavioral counselling) vs. Fitbit-only control group in reducing SB among PCS. Secondary outcomes include light-intensity PA, QoL, motivational outcomes, and patient satisfaction. METHODS: This two-armed, randomized controlled trial will recruit inactive PCS (stage I-IV) across Canada who self-report engaging in >8 hours/day of SB. Participants will be randomized to the intervention (n=60; Fitbit and behavioral support) or active control group (n=60; Fitbit-only). The intervention consists of the use of a Fitbit and a series of six behavioral support sessions (two group, four individual) to aid PCS in gradually replacing SB with light-intensity PA by increasing their daily step counts to 3,000 steps above their baseline values. The Fitbit-only control condition will receive a Fitbit and public health PA resources. The primary outcome is change in SB measured objectively using activPAL inclinometers. All secondary outcomes will be measured via self-report, except for PA which will be measuring using Fitbits. Data will be collected at baseline, post-intervention, and at 6-month post-intervention. DISCUSSION: Reducing SB and increasing light-intensity PA plays an important, yet often undervalued role in the health and well-being of PCS. This study will create a unique distance-based platform that can be used by clinical and community-based organizations as a low-cost, supportive care tool to improve health outcomes for PCS.

Associations of light physical activity, moderate-to-vigorous physical activity and sedentary behavior with quality of life in men on androgen deprivation therapy for prostate cancer: a quantile regression analysis.

To examine associations of physical activity (PA) and sedentary time (SED) with quality of life (QoL) in men on androgen deprivation therapy (ADT) for prostate cancer. A pooled analysis of 106 men on ADT was conducted. PA and SED were assessed using accelerometers. The Functional Assessment of Cancer Therapy (FACT) was used to assess self-reported QoL. Quantile regression examined the associations of QoL with PA and SED. Total time spent in SED was positively associated with FACT-General at the 50th (p = 0.010) and 75th percentile (p = 0.022). SED in ≥ 30-min bouts was inversely associated with FACT-General at the 50th  (p = 0.025) and 75th percentile (p = 0.029). Breaks in SED were positively associated with physical well-being at the 75th percentile (p = 0.004). Light-intensity PA was positively associated with FACT-Prostate at the 25th percentile (p = 0.020). SED and PA were associated with QoL outcomes, but time in each varied across men reporting the poorest QoL compared to those in the highest QoL distributions.

Examining the ability of the Cancer and Aging Research Group tool to predict toxicity in older men receiving chemotherapy or androgen-receptor-targeted therapy for metastatic castration-resistant prostate cancer.

BACKGROUND: Because multiple treatments are available for metastatic castrate-resistant prostate cancer (mCRPC) and most patients are elderly, the prediction of toxicity risk is important. The Cancer and Aging Research Group (CARG) tool predicts chemotherapy toxicity in older adults with mixed solid tumors, but has not been validated in mCRPC. In this study, its ability to predict toxicity risk with docetaxel chemotherapy (CHEMO) was validated, and its utility was examined in predicting toxicity risk with abiraterone or enzalutamide (A/E) among older adults with mCRPC. METHODS: Men aged 65+ years were enrolled in a prospective observational study at 4 Canadian academic cancer centers. All clinically relevant grade 2 to 5 toxicities over the course of treatment were documented via structured interviews and chart review. Logistic regression was used to identify predictors of toxicity. RESULTS: Seventy-one men starting CHEMO (mean age, 73 years) and 104 men starting A/E (mean age, 76 years) were included. Clinically relevant grade 3+ toxicities occurred in 56% and 37% of CHEMO and A/E patients, respectively. The CARG tool was predictive of grade 3+ toxicities with CHEMO, which occurred in 36%, 67%, and 91% of low, moderate, and high-risk groups (P = .003). Similarly, grade 3+ toxicities occurred among A/E users in 23%, 48%, and 86% with low, moderate, and high CARG risk (P < .001). However, it was not predictive of grade 2 toxicities with either treatment. CONCLUSIONS: There is external validation of the CARG tool in predicting grade 3+ toxicity in older men with mCRPC undergoing CHEMO and demonstrated utility during A/E therapy. This may aid with treatment decision-making.

Association of frailty with clinical outcomes in myelofibrosis: a retrospective cohort study.

There is limited understanding of the impact of frailty on clinical outcomes in patients with myelofibrosis (MF). In this retrospective cohort study on 439 chronic phase MF patients [mean age: 68·7 ± 12 years; median follow-up: 3·4 years (IQR 0·4-8·6)] from 2004 till 2018, we used a 35-variable frailty index (FI) to categorise patient's frailty status as fit (FI < 0·2, reference), prefrail (FI 0·2-0·29) or frail (FI ≥ 0·3). The association of frailty with overall survival (OS) and cumulative JAK inhibitor (JAKi) therapy failure was measured using hazard ratio (HR, 95% CI). In multivariable analysis, prefrail (HR 1·7, 1·1-2·5) and frail patients (HR 2·9, 1·6-5·5), those with higher DIPSS score (HR 2·5, 1·6-3·9) and transfusion dependency (HR 1·9, 1·3-2·9) had shorter OS. In a subset analysis of patients on JAKi treatment (n = 222), frail patients (HR 2·5, 1·1-5·7), patients with higher DIPSS score (HR 1·7, 1·0-3·1) and transfusion dependence (HR 1·7, 1·1-2·7) had higher cumulative incidence of JAKi failure. Age, comorbidities, ECOG performance status, and MPN driver mutations did not impact outcomes. Thus, higher frailty scores are associated with worse OS and increased JAKi failure in MF, and is a superior indicator of fitness in comparison to age, comorbidities, and performance status.

"This is my home-based exercise": exploring environmental influences on home-based exercise participation in oncology.

PURPOSE: Home-based exercise interventions offer many health benefits; however, the environments that constitute home-based exercise are not well-understood. The purpose of this study was to explore what constitutes the "home" for cancer survivors engaging in home-based exercise and identify factors of the environment that may impact exercise participation. METHODS: We conducted a qualitative exploratory study of cancer survivors receiving a home-based exercise prescription to manage their cancer-related impairments. Semi-structured interviews included photo elicitation to actively involve participants in the interview process and provide opportunities to visually "observe" environments utilized for home-based exercise. RESULTS: Sixteen participants were interviewed (n = 11 women, median age = 53.5, range = 26-74 years) and three themes emerged: (1) reasons for participating in a home-based exercise program; (2) physical environmental influences and preferences; and (3) social environmental influences and preferences. The ability to self-manage exercise and accommodate competing demands, having access to exercise facilities, feeling comfortable exercising without qualified supervision, and a desire for autonomy were reasons home-based exercise programs were preferred. Participants reported that the physical environment influenced their experience with home-based exercise and sub-themes related to a dynamic environment, indoor and outdoor characteristics, and aesthetics were identified. The social environment, with sub-themes associated with the presence of people, social climate, exercise modeling, connection, and exercise support, also related to exercise behavior. CONCLUSION: The findings highlight the influence of the physical and social environment on exercise prescription engagement. They further indicate the need for exercise professionals to consider the environment for exercise when delivering home-based exercise interventions.

The frequency and quality of delirium documentation in discharge summaries.

BACKGROUND: The National Institute for Health and Care Excellence recommends documenting all delirium episodes in the discharge summary using the term "delirium". Previous studies demonstrate poor delirium documentation rates in discharge summaries and no studies have assessed delirium documentation quality. The aim of this study was to determine the frequency and quality of delirium documentation in discharge summaries and explore differences between medical and surgical services. METHODS: This was a multi-center retrospective chart review. We included 110 patients aged ≥ 65 years identified to have delirium during their hospitalization using the Chart-based Delirium Identification Instrument (CHART-DEL). We assessed the frequency of any delirium documentation in discharge summaries, and more specifically, for the term "delirium". We evaluated the quality of delirium discharge documentation using the Joint Commission on Accreditation of Healthcare Organization's framework for quality discharge summaries. Comparisons were made between medical and surgical services. Secondary outcomes included assessing factors influencing the frequency of "delirium" being documented in the discharge summary. RESULTS: We identified 110 patients with sufficient chart documentation to identify delirium and 80.9 % of patients had delirium documented in their discharge summary ("delirium" or other acceptable term). The specific term "delirium" was reported in 63.6 % of all delirious patients and more often by surgical than medical specialties (76.5 % vs. 52.5 %, p = 0.02). Documentation quality was significantly lower by surgical specialties in reporting delirium as a diagnosis (23.5 % vs. 57.6 %, p < 0.001), documenting delirium workup (23.4 % vs. 57.6 %, p = 0.001), etiology (43.3 % vs. 70.4 %, p = 0.03), treatment (36.7 % vs. 66.7 %, p = 0.02), medication changes (44.4 % vs. 100 %, p = 0.002) and follow-up (36.4 % vs. 88.2 %, p = 0.01). CONCLUSIONS: The frequency of delirium documentation is higher than previously reported but remains subpar. Medical services document delirium with higher quality, but surgical specialties document the term "delirium" more frequently. The documentation of delirium in discharge summaries must improve to meet quality standards.

Impact of the early phase of the COVID pandemic on cancer treatment delivery and the quality of cancer care: a scoping review and conceptual model.

BACKGROUND: The disruption of health services due to coronavirus disease (COVID) is expected to dramatically alter cancer care; however, the implications for care quality and outcomes remain poorly understood. OBJECTIVE: We undertook a scoping review to evaluate what is known in the literature about how cancer treatment has been modified as a result of the COVID pandemic in patients receiving treatment for solid tumours, and what domains of quality of care are most impacted. METHODS: Citations were retrieved from MEDLINE and EMBASE (from 1 January 2019 to 28 October 2020), utilizing search terms grouped by the key concept (oncology, treatment, treatment modifications and COVID). Articles were excluded if they dealt exclusively with management of COVID-positive patients, modifications to cancer screening, diagnosis or supportive care or were not in English. Articles reporting on guidelines, consensus statements, recommendations, literature reviews, simulations or predictive models, or opinions in the absence of accompanying information on experience with treatment modifications in practice were excluded. Treatment modifications derived from the literature were stratified by modality (surgery, systemic therapy (ST) and radiotherapy) and thematically grouped. To understand what areas of quality were most impacted, modifications were mapped against the Institute of Medicine's quality domains. Where reported, barriers and facilitators were abstracted and thematically grouped to understand drivers of treatment modifications. Findings were synthesized into a logic model to conceptualize the inter-relationships between different modifications, as well as their downstream impacts on outcomes. RESULTS: In the 87 retained articles, reductions in outpatients visits (26.4%) and delays/deferrals were commonly reported across all treatment modalities (surgery: 50%; ST: 55.8% and radiotherapy: 56.7%), as were reductions in surgical capacity (57.1%), alternate systemic regimens with longer treatment intervals or use of oral agents (19.2%) and the use of hypofractionated radiotherapy regimens (40.0%). Delivery of effective, timely and equitable care was the quality domains found to be the most impacted. The most commonly reported facilitator of maintaining cancer care delivery levels was the shift to virtual models of care (62.1%), while patient-initiated deferrals and cancellations (34.8%), often due to fear of contracting COVID (60.9%), was a commonly reported barrier. CONCLUSIONS: As it will take a considerable amount of time for the cancer system to resume capacity and adjust models of care in response to the pandemic, these treatment delays and modifications will likely be prolonged and will negatively impact the quality of care and patient outcomes.

Associations between self-reported physical activity, quality of life, and emotional well-being in men with prostate cancer on active surveillance.

OBJECTIVE: The relationship between physical activity (PA) and quality of life (QOL) relative to active treatment for prostate cancer (PCa) has been well-studied; however, little is known about this relationship during active surveillance (AS). Moreover, whether PA is associated with better emotional well-being (EWB) in men with low-risk PCa requires further investigation. Accordingly, we examined the association between self-reported PA and the average change in QOL and EWB over time during AS. METHODS: A total of 630 men on AS were included in this retrospective, longitudinal study from AS initiation until AS discontinuation. Generalized estimated equations were used to determine the association between self-reported PA (independent variable) and QOL and EWB (dependent variables) over time, adjusting for participants' age. RESULTS: QOL was higher over time in active ( ß^ (95%CI) = 1.14 (0.11, 2.16), P = .029) and highly active participants ( ß^ (95%CI) = 1.62 (0.58, 2.67), P = .002) compared to their inactive counterparts. Highly active participants had 55% greater odds of experiencing high EWB relative to inactive participants (OR (95%CI) = 1.55 (1.11, 2.16), P = .010). In men with low EWB at baseline (median = 3 months after diagnosis), the highest levels of PA (>1000 metabolic equivalent-minutes per week) were associated with high EWB over time (OR (95%CI) = 2.17 (1.06, 4.46), P = .034). CONCLUSIONS: These data further support the importance of PA as a supportive care strategy for men on AS. Our findings suggest that engaging in higher volumes of PA post-diagnosis may be beneficial particularly for men exhibiting low emotional well-being early on during AS.

Organ donation and transplant: The Islamic perspective.

Islam is the second most practiced religion globally, and the number of Muslims in Western countries has been increasing due to recent trends in migration. Studies have shown that Muslims in the Western world have more negative attitudes toward organ donation and transplantation compared with individuals from other religious backgrounds. Multiple barriers have been postulated that may prevent Muslims from exploring organ donation or transplantation. We conducted a literature review with the goal of summarizing the opinions of major Sunni and Shia scholars and Islamic bodies about organ donation and transplantation, including their opinions and rulings on the neurological determination of death to inform healthcare professionals, community members, and leaders. We also identified factors and attitudes that may prevent members of the Muslim community from achieving equitable access to transplantation or from consenting to donate organs during life or after death. Key factors or concerns identified included: lack of information regarding organ donation, mistrust of the healthcare system, family opinions, sacredness of the body, lack of clear understanding of religious rulings, and opinions of religious leaders. Studies have suggested that partnering with religious leaders to address these concerns may help foster positive attitudes toward organ donation and transplantation.

Variability and limitations in home-based exercise program descriptions in oncology: a scoping review.

BACKGROUND: The literature reflects considerable heterogeneity in what constitutes home-based exercise interventions. The variability for where and what "home-based" exercise can represent challenges interpretation of findings and appropriate advocacy, referral, or development of these models of care. Therefore, the objective of this review was to provide a comprehensive summary of how home-based exercise is defined and reported in the literature and summarize the range of supportive elements utilized in home-based exercise trials. METHODS: We followed methodology for scoping reviews. Relevant research databases were searched from inception to March 2019. Two reviewers independently screened articles to determine eligibility and extracted terminology used to describe home-based exercise and intervention details for intervention delivery. RESULTS: Of the 9432 records identified, 229 articles met inclusion criteria. Across the literature, exercise interventions were described as home-based if they were completed at-home, outdoors in the neighbourhood, and in community facilities; or in self-selected environments; or if they were unsupervised. Supportive elements for home-based models ranged with respect to the amount of supervision and resources utilized, including the provision of print materials, exercise equipment, telephone support, home visits, and technology. CONCLUSIONS: This review provides a comprehensive summary of strategies previously utilized to deliver home-based exercise interventions in oncology, along with the various definitions of the home-based environment for exercise reported by researchers. Specific recommendations to improve the prescription and reporting of home-based exercise interventions are provided in order to facilitate the delivery, evaluation, and translation of findings into clinical practice.

Screening and Treatment for Osteoporosis After Stroke.

Background and Purpose- Stroke is a risk factor for subsequent osteoporosis and fractures. We sought to understand current rates and predictors of screening and treatment for bone loss after stroke. Methods- Using the Ontario Stroke Registry from July 1, 2003 to March 31, 2013, we identified patients ≥65 years who were seen in the emergency department or hospitalized with stroke at 11 regional stroke centers in Ontario, Canada and discharged alive. We calculated the cumulative incidence of (1) screening with bone mineral density testing and (2) treatment with medications for fracture prevention, within 1 year after the index stroke, accounting for the competing risk of death. We then used cause-specific hazard models to estimate the effect of various covariates on the cause-specific hazard of bone mineral density testing and osteoporosis pharmacotherapy. Results- In the sample of 16 581 patients, 5.1% overall and 2.9% of those without prior testing underwent screening bone mineral density testing, and 15.5% overall and 3.2% of those not previously on treatment were prescribed medications for fracture prevention within 1 year after stroke. Results were similar in all subgroups of patients. Female sex, prestroke osteoporosis, and poststroke falls and fractures were associated with increased rates of osteoporosis pharmacotherapy. Conclusions- Patients with recent stroke are infrequently screened and treated for osteoporosis, which may increase the risk of fractures. Future work should focus on identifying and treating patients who are at increased risk of fractures after stroke.

Development, implementation, and effects of a cancer center's exercise-oncology program.

BACKGROUND: National and international bodies acknowledge the benefit of exercise for people with cancer, yet limited accessibility to related programing remains. Given their involvement in managing the disease, cancer centers can play a central role in delivering exercise-oncology services. The authors developed and implemented a clinically integrated exercise-oncology program at a major cancer center and evaluated its effectiveness and participant experience. METHODS: A hospital-based program with prescribed at-home exercise was developed and accepted referrals over a 42-month period (3.5 years). Implementation was conducted in 2 phases: a pilot phase for women with breast cancer and men with genitourinary cancer and a roll-out phase for all patients with cancer. Enrolled patients were assessed and received an exercise prescription as well as a program manual, resistance bands, and a stability ball from a kinesiologist. Program participation and effectiveness were evaluated up to 48 weeks after the baseline assessment using intention-to-treat analyses. Participants in the roll-out phase were asked to complete a program experience questionnaire at the completion of the 48-week follow-up. RESULTS: In total, 112 participants enrolled in the pilot, and 150 enrolled in the roll-out phase. Program attrition to 48 weeks was 48% and 65% in the pilot and roll-out phases, respectively. In participants who consented to research evaluation of their performance, objective and patient-reported measures of functional capacity improved significantly from baseline in both phases. Participants were highly satisfied with the program. CONCLUSIONS: Despite significant drop-out to program endpoints, our cancer-exercise program demonstrated clinically relevant improvement in functional outcomes and was highly appreciated by participants.

Influence of physical activity on active surveillance discontinuation in men with low-risk prostate cancer.

PURPOSE: Epidemiologic data suggest that high levels of physical activity (PA) may reduce the risk of disease progression in men with prostate cancer (PCa), but it is unknown whether PA can delay the requirement for definitive treatment for those on active surveillance (AS). We investigated the influence of PA post-diagnosis on AS discontinuation in men with low-risk disease. METHODS: The effect of PA on the time to AS discontinuation was assessed in 421 patients, of whom 107 underwent additional PCa treatment over a median of 2.5 years. RESULTS: Using Cox regression models, we found that PA was not significantly associated with time to curative treatment initiation. Prostate-specific antigen (PSA) most proximal to AS initiation (HR, 1.11; 95% CI 1.03 to 1.21) and the number of positive cores (HR, 1.34; 95% CI 1.12 to 1.61) at diagnosis were associated with a significantly increased risk of discontinuing AS. CONCLUSION: Our findings suggest that PA during AS for PCa does not significantly influence time to curative treatment.
