This review focused on the identification of patient-reported outcome measures (PROMs) used in routine cancer clinical practice, the impact on patient, provider, and system outcomes, and the implementation factors influencing uptake. A scoping review of the published health literature was conducted using empirical databases, namely, Ovid Medline (2003 to September 2013), CINAHL (2003–2013) and PsycINFO (2003–2013). Scoping reviews are systematic literature reviews in a broad topic area that provide relevant and quantified results about the knowledge available on a particular topic and aim to rapidly map and synthesize the evidence to emphasize what is known. From a total of 2447 unique publications, 30 articles that met eligibility criteria were reviewed. PRO use appears to be acceptable to patients, enables earlier detection of symptoms and may improve communication between clinicians and patients. However, the impact of routine PROMs collection on health outcomes is less clear and high-quality research is still warranted. PROMs use in routine cancer clinical practice is growing with improvements on essential care processes shown but a number of implementation barriers must still be addressed. The lack of standardization in PROMs used in cancer organizations may make it difficult to use these data for quality monitoring in the future.

Purpose: Ontario's cancer system is unique because it has implemented two standardized assessment tools population-wide to improve care: the Edmonton Symptom Assessment System (ESAS) measures severity of nine symptoms (scale 0 to 10; 10 indicates the worst) and the Palliative Performance Scale (PPS) measures performance status (scale 0 to 100; 0 indicates death). This article describes the trajectory of ESAS and PPS scores 6 months before death. Patients and Methods: Observational cohort study of cancer decedents between 2007 and 2009. Decedents required ≥1 ESAS or PPS assessment in the 6 months before death for inclusion. Outcomes were the decedents' average ESAS and PPS scores per week before death. Results: Ten thousand seven hundred fifty-two (ESAS) and 7,882 (PPS) decedents were included. The mean age was 65 years, half were female, and approximately 75% of assessments occurred in cancer clinics. Average PPS score declined slowly over the 6 months before death, starting at approximately 70 and ending at 40, declining more rapidly in the last month. For ESAS symptoms, average pain, nausea, anxiety, and depression scores remained relatively stable over the 6 months. Conversely, shortness of breath, drowsiness, well-being, lack of appetite, and tiredness increased in severity over time, particularly in the month before death. More than one third of the cohort reported moderate to severe scores (ie, 4 to 10) for most symptoms in the last month of life. Conclusion: In this large outpatient cancer population, trajectories of mean ESAS scores followed two patterns: increasing versus generally flat. The latter was perhaps due to available treatment (eg, prescriptions) for those symptoms. Future research should prioritize addressing symptoms that worsen over time.

Cancer is a disease that affects mostly older adults. Older adults often have other chronic health conditions in addition to cancer and may have different health priorities, both of which can impact cancer treatment decision-making. However, no systematic review of factors that influence an older cancer patient's decision to accept or decline cancer treatment has been conducted. Systematic review of the literature published between inception of the databases and February 2013. Dutch, English, French or German articles reporting on qualitative studies, cross-sectional, longitudinal observational or intervention studies describing factors why older adults accepted or declined cancer treatment examining actual treatment decisions were included. Ten databases were used. Two independent reviewers reviewed manuscripts and performed data abstraction using a standardized form and the quality of studies was assessed with the Mixed Methods Appraisal Tool. Of 17,343 abstracts reviewed, a total of 38 studies were included. The majority focused on breast and prostate cancer treatment decisions and most studies used a qualitative design. Important factors for accepting treatment were convenience and success rate of treatment, seeing necessity of treatment, trust in the physician and following the physician's recommendation. Factors important for declining cancer treatment included concerns about the discomfort of the treatments, fear of side effects and transportation difficulties. Although the reasons why older adults with cancer accepted or declined treatment varied considerably, the most consistent determinant was physician recommendation. Further studies using large, representative samples and exploring decision-making incorporating health literacy and comorbidity are needed.

There is a considerable body of research linking elements of Leventhal's Common Sense Model (CSM) to emotional well-being/distress outcomes among people with physical illness. The present study aims to consolidate this literature and examine the evidence for the role of coping strategies within this literature. A systematic review was conducted where the outcomes of interest were: depression, anxiety and quality of life. A total of 1050 articles were identified and 31 articles were considered eligible to be included in the review. Across a range of illnesses, perceptions of consequences of the illness and emotional representations were consistently the illness perceptions with the strongest relationship with the outcomes. Coping variables tend to be stronger predictors of outcomes than the illness perception variables. The evidence for the mediating effect of coping was inconsistent. Illness perceptions and coping have an important role to play in the explanation of distress outcomes across a range of physical health conditions. However, some clarity about the theoretical position of coping in relation to illness perceptions, and further longitudinal work is needed if we are to apply this information to the design of interventions for the improvement of psychological health among people with physical health conditions.
