Purpose: To develop a transdisciplinary conceptualization of social belonging that could be used to guide measurement approaches aimed at evaluating the effectiveness of community-based programs for ...people with disabilities.
Method: We conducted a narrative, scoping review of peer reviewed English language literature published between 1990 and July 2011 using multiple databases, with "sense of belonging" as a key search term. The search engine ranked articles for relevance to the search strategy. Articles were searched in order until theoretical saturation was reached. We augmented this search strategy by reviewing reference lists of relevant papers.
Results: Theoretical saturation was reached after 40 articles; 22 of which were qualitative accounts. We identified five intersecting themes: subjectivity; groundedness to an external referent; reciprocity; dynamism and self-determination.
Conclusion: We define a sense of belonging as a subjective feeling of value and respect derived from a reciprocal relationship to an external referent that is built on a foundation of shared experiences, beliefs or personal characteristics. These feelings of external connectedness are grounded to the context or referent group, to whom one chooses, wants and feels permission to belong. This dynamic phenomenon may be either hindered or promoted by complex interactions between environmental and personal factors.
Implications for Rehabilitation
Sense of belonging
Program evaluation and monitoring exist in order to measure success and outcomes of rehabilitation practice.
Sense of belonging is one of the goals of rehabilitation services, but has not yet been defined unambiguously, making it difficult for practitioners to understand if they are achieving these goals.
Researchers and practitioners in rehabilitation can define a sense of belonging as a subjective feeling of value and respect derived from a reciprocal relationship to an external referent that is built on a foundation of shared experiences, beliefs or personal characteristics when conceptualizing and designing tools to measure sense of belonging as an outcomes of their services.
Objective To determine the association between exposure to radiotherapy for the treatment of prostate cancer and subsequent second malignancies (second primary cancers).Design Systematic review and ...meta-analysis of observational studies.Data sources Medline and Embase up to 6 April 2015 with no restrictions on year or language.Study selection Comparative studies assessing the risk of second malignancies in patients exposed or unexposed to radiotherapy in the course of treatment for prostate cancer were selected by two reviewers independently with any disagreement resolved by consensus.Data extraction and synthesis Two reviewers independently extracted study characteristics and outcomes. Risk of bias was assessed with the Newcastle-Ottawa scale. Outcomes were synthesized with random effects models and Mantel-Haenszel weighting. Unadjusted odds ratios and multivariable adjusted hazard ratios, when available, were pooled.Main outcome measures Second cancers of the bladder, colorectal tract, rectum, lung, and hematologic system.Results Of 3056 references retrieved, 21 studies were selected for analysis. Most included studies were large multi-institutional reports but had moderate risk of bias. The most common type of radiotherapy was external beam; 13 studies used patients treated with surgery as controls and eight used patients who did not undergo radiotherapy as controls. The length of follow-up among studies varied. There was increased risk of cancers of the bladder (four studies; adjusted hazard ratio 1.67, 95% confidence interval 1.55 to 1.80), colorectum (three studies; 1.79, 1.34 to 2.38), and rectum (three studies; 1.79, 1.34 to 2.38), but not cancers of the hematologic system (one study; 1.64, 0.90 to 2.99) or lung (two studies; 1.45, 0.70 to 3.01), after radiotherapy compared with the risk in those unexposed to radiotherapy. The odds of a second cancer varied depending on type of radiotherapy: treatment with external beam radiotherapy was consistently associated with increased odds while brachytherapy was not. Among the patients who underwent radiotherapy, from individual studies, the highest absolute rates reported for bladder, colorectal, and rectal cancers were 3.8%, 4.2%, and 1.2%, respectively, while the lowest reported rates were 0.1%, 0.3%, and 0.3%.Conclusion Radiotherapy for prostate cancer was associated with higher risks of developing second malignancies of the bladder, colon, and rectum compared with patients unexposed to radiotherapy, but the reported absolute rates were low. Further studies with longer follow-up are required to confirm these findings.
Objectives To identify inequalities in cancer survival rates for patients with a history of severe psychiatric illness (SPI) compared to those with no history of mental illness and explore ...differences in the provision of recommended cancer treatment as a potential explanation. Design Population-based retrospective cohort study using linked cancer registry and administrative data at ICES. Setting The universal healthcare system in Ontario, Canada. Participants Colorectal cancer (CRC) patients diagnosed between April 1st, 2007 and December 31st, 2012. SPI history (schizophrenia, schizoaffective disorders, other psychotic disorders, bipolar disorders or major depressive disorders) was determined using hospitalization, emergency department, and psychiatrist visit data and categorized as 'no history of mental illness, 'outpatient SPI history', and 'inpatient SPI history'. Main outcome measures Cancer-specific survival, non-receipt of surgical resection, and non-receipt of adjuvant chemotherapy or radiation. Results 24,507 CRC patients were included; 482 (2.0%) had an outpatient SPI history and 258 (1.0%) had an inpatient SPI history. Individuals with an SPI history had significantly lower survival rates and were significantly less likely to receive guideline recommended treatment than CRC patients with no history of mental illness. The adjusted HR for cancer-specific death was 1.69 times higher for individuals with an inpatient SPI (95% CI 1.36-2.09) and 1.24 times higher for individuals with an outpatient SPI history (95% CI 1.04-1.48). Stage II and III CRC patients with an inpatient SPI history were 2.15 times less likely (95% CI 1.07-4.33) to receive potentially curative surgical resection and 2.07 times less likely (95% CI 1.72-2.50) to receive adjuvant radiation or chemotherapy. These findings were consistent across multiple sensitivity analyses. Conclusions Individuals with an SPI history experience inequalities in colorectal cancer care and survival within a universal healthcare system. Increasing advocacy and the availability of resources to support individuals with an SPI within the cancer system are warranted to reduce the potential for unnecessary harm.
Integrating diverse types of prognostic information into accurate, individualized estimates of outcome in colorectal cancer is challenging. Significant heterogeneity in colorectal cancer ...prognostication tool quality exists. Methodology is incompletely or inadequately reported. Evaluations of the internal or external validity of the prognostic model are rarely performed. Prognostication tools are important devices for patient management, but tool reliability is compromised by poor quality. Guidance for future development of prognostication tools in colorectal cancer is needed.
Abstract
Introduction
With increasing interest in income-related differences in cancer outcomes, accurate measurement of income is imperative. Misclassification of income can result in wrong ...conclusions as to the presence of income inequalities. We determined misclassification between individual- and neighborhood-level income and their association with overall survival among colorectal cancer (CRC) patients.
Methods
The Canadian Census Health and Environment Cohorts were used to identify CRC patients diagnosed from 1992 to 2017. We used neighborhood income quintiles from Statistics Canada and created individual income quintiles from the same data sources to be as similar as possible. Agreement between individual and neighborhood income quintiles was measured using cross-tabulations and weighted kappa statistics. Cox proportional hazards and Lin semiparametric hazards models were used to determine the effects of individual and neighborhood income independently and jointly on survival. Analyses were also stratified by rural residence.
Results
A total of 103 530 CRC patients were included in the cohort. There was poor agreement between individual and neighborhood income with only 17% of respondents assigned to the same quintile (weighted kappa = 0.18). Individual income had a greater effect on relative and additive survival than neighborhood income when modeled separately. The interaction between individual and neighborhood income demonstrated that the most at risk for poor survival were those in the lowest individual and neighborhood income quintiles. Misclassification was more likely to occur for patients residing in rural areas.
Conclusion
Cancer researchers should avoid using neighborhood income as a proxy for individual income, especially among patients with cancers with demonstrated inequalities by income.
To examine the association between Textbook Outcome (TO)-a new composite quality measurement-and long-term survival in gastric cancer surgery.
Single-quality indicators do not sufficiently reflect ...the complex and multifaceted nature of perioperative care in patients with gastric adenocarcinoma.
All patients undergoing gastrectomy for nonmetastatic gastric adenocarcinoma registered in the Population Registry of Esophageal and Stomach Tumours of Ontario (PRESTO) between 2004 and 2015 were included. TO was defined according to negative margins; >15 lymph nodes sampled; no severe complications; no re-interventions; no unplanned ICU admission; length of stay ≤21 days; no 30-day readmission; and no 30-day mortality. Three-year survival was estimated using the Kaplan-Meier method. A marginal multivariable Cox proportional-hazards model was used to estimate the association between achieving TO metrics and long-term survival. E-value methodology was used to assess for risk of residual confounding.
Of the 1836 patients included in this study, 402 (22%) achieved all TO metrics. TO patients had a higher 3-year survival rate compared to non-TO patients (75% vs 55%, log-rank P < 0.001). After adjustments for covariates and clustering within hospitals, TO was associated with a 41% reduction in mortality (adjusted hazards ratio 0.59, 95% confidence interval 0.48, 0.72, P < 0.001). These results were robust to potential residual confounding.
Achieving TO is strongly associated with improved long-term survival in gastric cancer patients and merits further focus in surgical quality improvement efforts.
Objectives
This cross-sectional study examines the dental caries experience of new Canadian Armed Forces (CAF) members in relation to enrollment from municipalities with and without water ...fluoridation.
Methods
The study population consisted of recruits who enrolled in the CAF between 2006 and 2017 with an enrollment address in municipalities with known fluoridation status (
n
= 24,552). Odontogram statistics from dental examinations were used to calculate the number of decayed, missing, and filled teeth (DMFT) and tooth surfaces (DMFS) for each recruit. The average difference between recruits from municipalities with and without fluoridation was determined using a linear regression model which adjusted for confounding by age and gender and allowed effect modification based on socio-economic status.
Results
The average recruit was male, 24 years of age, with 5.6 DMFT and 11.6 DMFS. After adjusting for age and gender, recruits residing in municipalities with water fluoridation had lower DMFT by 0.67 (CI − 0.55, − 0.79) points and lower DMFS by 1.77 (− 1.46, − 2.09) points. When allowing for effect modification by median income quintile of the recruits’ home census tract, the average reduction in DMFT and DMFS was similar in all income quintiles, with average reductions in DMFT ranging from 0.47 to 1.02 and average reductions in DMFS ranging from 1.33 to 2.70.
Conclusion
Residence in a municipality with water fluoridation was associated with reduced caries experience in a national sample of newly enrolled CAF members. The benefits of water fluoridation were uniform across neighbourhood income and military rank classes.
Functional outcomes are central to cancer care decision-making by older adults.
To assess the long-term functional outcomes of older adults after a resection for cancer using time at home as the ...measure.
This population-based cohort study was conducted in Ontario, Canada, using the administrative databases stored at ICES (formerly the Institute for Clinical Evaluative Sciences). The analysis included adults 70 years or older with a new diagnosis of cancer between January 1, 2007, and December 31, 2017, who underwent a resection 90 days to 180 days after the diagnosis. Patients were followed up until and censored at the date of death, date of last contact, or December 31, 2018.
The main outcome was time at home, dichotomized as high time at home (defined as ≤14 institution days annually) and low time at home (defined as >14 institution days) during the 5 years after surgical cancer treatment. Time-to-event analyses with Kaplan-Meier methods and multivariable Cox proportional hazards regression models were used.
A total of 82 037 patients were included, with a median (interquartile range) follow-up of 46 (23-80) months. Of these patients, 52 119 were women (63.5%) and the mean (SD) age was 77.5 (5.7) years. The median (interquartile range) number of days at home per days alive per patient was high, at 0.98 (0.94-0.99) in postoperative year 1, 0.99 (0.97-1.00) in year 2, 0.99 (0.96-1.00) in year 3, 0.99 (0.96-1.00) in year 4, and 0.99 (0.96-1.00) in year 5. The probability of high time at home was 70.3% (95% CI, 70.0%-70.6%) at postoperative year 1 and 53.2% (95% CI, 52.8%-53.5%) at postoperative year 5. Advancing age (≥85 years: hazard ratio HR, 2.11; 95% CI, 2.04-2.18); preoperative frailty (HR, 1.74; 95% CI, 1.68-1.80); high material deprivation (5th quintile: HR, 1.25; 95% CI, 1.20-1.29); rural residency (HR, 1.14; 95% CI, 1.10-1.18); high-intensity surgical procedure (HR, 2.04; 95% CI, 1.84-2.25); and gastrointestinal (HR, 1.23; 95% CI, 1.18-1.27), gynecologic (HR, 1.31; 95% CI, 1.18-1.45), and oropharyngeal (HR, 1.05; 95% CI, 0.95-1.16) cancers were associated with low time at home. Inpatient acute care was responsible for 76.0% and long-term care was responsible for 2.0% of institution days in postoperative year 1. Inpatient days decreased to 31.0% by year 3, but days in long-term care increased over time.
This study found that older adults predominantly experienced high time at home after resection for cancer, reflecting the overall favorable functional outcomes in this population. The oldest adults and those with preoperative frailty and material deprivation appeared to be the most vulnerable to low time at home, and efforts to optimize and manage expectations about surgical outcomes can be targeted for this population; this information is important for patient counseling regarding surgical cancer treatment and for preparation for postoperative recovery.
Clinical, pathological, and molecular information combined with cancer stage in prognostication algorithms can offer more personalized estimates of survival, which might guide treatment choices. Our ...aim was to evaluate the quality of prognostication tools in esophageal cancer.
We systematically searched MedLine and Embase from 2005 to 2017 for studies reporting development or validation of models predicting long-term survival in esophageal cancer. We evaluated tools using the Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modelling Studies guidelines and the American Joint Committee on Cancer acceptance criteria for risk models.
We identified 16 prognostication tools for patients treated with curative intent and 1 for patients with metastatic disease. These tools frequently excluded adenocarcinoma, contained outdated data, and were developed with a limited sample size. Nine tools were developed in China for squamous cell cancer, and 11 used data on patients diagnosed before 2010. Most tools excluded key prognostic factors such as age and sex. Tumor stage and grade were the most commonly, but not universally, included factors. Twelve tools were designed to predict overall survival; 5 predicted cancer-specific survival. Bootstrap internal validation was performed for most tools; c-statistics ranged from 0.63 to 0.77 and graphically evaluated calibration was “good.” Five tools were externally validated; c-statistics ranged from 0.70 to 0.77.
Existing tools cannot be confidently used for esophageal cancer prognostication in current clinical practice. Better-quality tools might help to more individually and accurately estimate disease course, select further treatments, and risk-stratify for future clinical trials.
