Quality Assurance and Prevention of COVID-19 Before Admission in Geriatric Rehabilitation Unit in Long-Term Care Facilities.

Background: This quality assurance study was conducted during the COVID-19 pandemic to describe the profile of patients aged 65 years and older admitted to a transition unit in a long-term care (LTC) facility and to evaluate the impact of admission modalities, compliance with screening and hand hygiene practices, risk of COVID-19, and time to access a geriatric rehabilitation unit (GRU). Methods: A prospective study was conducted using administrative and medical records from three Montreal public LTC facilities offering a rehabilitation program for 312 patients admitted between May 2020 and February 2021. The results are reported for the entire sample and compared according to the mode of admission. Results: The incidence of COVID-19 during the transition unit stay was estimated to be 11 cases or 3.5% in 14 days. Assessment of screening compliance showed deficiencies for 41.3% of patients, and the frequency of hand hygiene audits was not strictly adhered to. More COVID-19 cases were recorded in patients admitted to the transition unit by bed availability than in the cohort mode. The time to access a rehabilitation unit was 7.2 days or 23.5% shorter for patients admitted by bed availability. Conclusions: The study, conducted from a continuous practice improvement perspective, showed that the implementation of a transition unit in the LTC facilities helped control the transmission of COVID-19, but also revealed flaws in screening and hand hygiene practices.

Consumption of ultra-processed foods and obesity in Canada.

OBJECTIVES: To assess the association between consumption of ultra-processed foods and obesity in the Canadian population. METHODS: Cross-sectional study including 19,363 adults aged 18 years or more from the 2004 Canadian Community Health Survey, cycle 2.2. Ultra-processed food intake was estimated using daily relative energy intake of ultra-processed food (% of total energy intake) from data obtained by 24-h food recalls. Obesity was assessed using body mass index (BMI ≥ 30 kg/m2). Univariate and multivariate linear regressions were performed to describe ultra-processed food consumption according to socio-economic and demographic variables, and multivariate logistic regression was performed to verify the association between ultra-processed food consumption and obesity, adjusting for potential confounders, including socio-demographic factors, physical activity, smoking, immigrant status, residential location, and measured vs self-reported weight and height. RESULTS: Ultra-processed foods make up almost half (45%) of the daily calories consumed by Canadian adults. Consumption of these foods is higher among men, younger adults, those with fewer years of formal education, smokers, those physically inactive, and Canadian-born individuals. Ultra-processed food consumption is positively associated with obesity. After adjusting for confounding factors, individuals in the highest quintile of ultra-processed food consumption were 32% more likely of having obesity compared to individuals in the first quintile (predicted OR = e0.005 × 56 = 1.32; 95% CI = 1.05-1.57). CONCLUSION: Canadians would benefit from reducing consumption of ultra-processed foods and beverages and increasing consumption of freshly prepared dishes made from unprocessed or minimally processed foods.

Feasibility of Implementing an Exercise Program in a Geriatric Assessment Unit: the SPRINT Program.

BACKGROUND: An exercise program involving patients, caregivers, and professionals, entitled SPecific Retraining in INTerdisciplinarity (SPRINT), has been developed to prevent functional decline during hospitalization of older patients. GOAL: Assess the feasibility of implementing SPRINT in the context of a Geriatric Assessment Unit (GAU). METHODS: GAU's health-care professionals were instructed with the SPRINT. All new patients were evaluated by a physiotherapist shortly after admission to validate the eligibility criteria and allocation category of exercises. Questionnaires on physical activities were filled out by professionals, patients, and caregivers at baseline and after intervention. Quantitative and qualitative information was collected on adherence to the program. RESULTS: SPRINT was applied to 19 of the 50 patients admitted during the three-month pilot study. A daily average of one exercise session per patient was performed, most frequently with a nurse (37%), physician (20%), care attendant (13%) or by the patient alone (22%). The caregivers participated only 4% of the time. Barriers and facilitators in applying SPRINT have been identified. CONCLUSIONS: SPRINT appears relevant and applicable within GAUs. Future studies should be conducted to assess its safety and effectiveness in preventing hospital-related functional decline.

Prevalence of Convergence Insufficiency-Type Symptomatology in Parkinson's Disease.

BACKGROUND: Individuals with Parkinson's disease (PD) often present with visual symptoms (e.g., difficulty in reading, double vision) that can also be found in convergence insufficiency (CI). Our objective was to estimate the prevalence of CI-type visual symptomatology in individuals with PD, in comparison with controls. METHODS: Participants ≥50 years with (n=300) and without (n=300) PD were recruited. They were administered the Convergence Insufficiency Symptom Survey (CISS-15) over the phone. A score of ≥21 on the CISS-15, considered positive for CI-type symptomatology, served as the cutoff. Data from individuals (n=87 with, n=94 without PD) who were approached but who reported having a known oculovisual condition were analysed separately. Student's t test and chi-square at the 0.05 level were employed for statistical significance. RESULTS: A total of 29.3% of participants with versus 7.3% without PD presented with a score of ≥21 on the CISS-15 (p=0.001). Of the participants having a known oculovisual condition, 39.1% with versus 19.1% without PD presented with a score of ≥21 on the CISS-15 (p=0.01). CONCLUSIONS: The prevalence of CI-type visual symptoms is higher in individuals with versus without PD whether or not they have a coexisting oculovisual condition. These results suggest that PD per se places individuals with the disease at greater risk of visual symptomatology. These results further underline the importance of providing regular eye exams for individuals with PD.

Structural analysis of health-relevant policy-making information exchange networks in Canada.

BACKGROUND: Health systems worldwide struggle to identify, adopt, and implement in a timely and system-wide manner the best-evidence-informed-policy-level practices. Yet, there is still only limited evidence about individual and institutional best practices for fostering the use of scientific evidence in policy-making processes The present project is the first national-level attempt to (1) map and structurally analyze-quantitatively-health-relevant policy-making networks that connect evidence production, synthesis, interpretation, and use; (2) qualitatively investigate the interaction patterns of a subsample of actors with high centrality metrics within these networks to develop an in-depth understanding of evidence circulation processes; and (3) combine these findings in order to assess a policy network's "absorptive capacity" regarding scientific evidence and integrate them into a conceptually sound and empirically grounded framework. METHODS: The project is divided into two research components. The first component is based on quantitative analysis of ties (relationships) that link nodes (participants) in a network. Network data will be collected through a multi-step snowball sampling strategy. Data will be analyzed structurally using social network mapping and analysis methods. The second component is based on qualitative interviews with a subsample of the Web survey participants having central, bridging, or atypical positions in the network. Interviews will focus on the process through which evidence circulates and enters practice. Results from both components will then be integrated through an assessment of the network's and subnetwork's effectiveness in identifying, capturing, interpreting, sharing, reframing, and recodifying scientific evidence in policy-making processes. DISCUSSION: Knowledge developed from this project has the potential both to strengthen the scientific understanding of how policy-level knowledge transfer and exchange functions and to provide significantly improved advice on how to ensure evidence plays a more prominent role in public policies.

Orthoptic Treatment of Convergence Insufficiency in Parkinson's Disease: A Case Series.

Introduction: This study reports a case series of orthoptic treatment (OT) for convergence insufficiency (CI) in individuals with Parkinson's disease (PD). Method: We are reporting two cases of individuals with PD who completed OT for CI. Both had a confirmed diagnosis of CI, accompanied by CI-type symptomatology. They each underwent an OT program consisting of three office-based visits and 8 weeks of home-based exercises. Treatment outcome was based on the changes measured pre- versus post-OT on the near point of convergence, positive fusional vergences, and symptomatology score. Results: The two participants successfully completed therapy, gained ability to converge, had fewer symptoms, and were satisfied with the OT-induced changes they felt in their day-to-day lives. Conclusion: This case series show that OT for CI in PD is possible. Further research is required as these results demonstrate that OT has the potential to improve symptomatic CI in these patients. In the meantime, the positive results obtained in these two cases should encourage clinicians to consider OT (a therapy with no/minimal risk) for CI in patients with PD whose quality of life is affected by this binocular dysfunction.

Visual impairment in older institutionalised Canadian seniors with dementia.

PURPOSE: To estimate the prevalence of visual impairment (VI) in a sub-population of Canadian long-term care facilities, i.e. residents affected by dementia. METHODS: This study was conducted in the long-term care facility units at the Institut universitaire de gériatrie de Montréal. All residents ≥65 years old (y.o.), having a clinical diagnosis of dementia, and able to understand French or English, were eligible for participation in the study. All residents participating in the study received a complete eye exam by an experienced optometrist. For the purpose of the study, VI was defined as a distance visual acuity (VA) <6/12 (0.30 logMAR, 20/40) in the better seeing eye. RESULTS: One hundred and fifty residents, 68-102 y.o. took part into the study. All participants had a diagnosis of dementia recorded in their clinical chart. VI was present in 37.3% (95% CI: 29.1-46.1%) (n = 50) of residents in whom monocular VA could be measured. Ocular refraction for their better seeing eye improved the VA to ≥6/12 (0.30 logMAR, 20/40) in 40% (n = 20) of those 50 residents. When VI remained after refraction, it was due in order of frequency to cataract, age-related macular degeneration, and primary open angle glaucoma. CONCLUSIONS: Our data showed that an appreciable proportion (37.3%) of older residents with dementia also have VI, and that VI can be corrected in many by updating their refraction. Others could potentially be helped through cataract surgery. It is therefore important to offer regular eye care services to those residents, knowing that many are not able to express their visual needs.

Tool for Screening Visual Acuity in Older Individuals With Dementia.

Rationale/Objective: To develop a screening and referral algorithm tool to help identify which older institutionalized individuals with dementia need an eye examination. METHODS: The visual acuity (VA) screening test was developed on an iPad retina display. Three optotypes were used (letters, numbers, and tumbling E's) to determine whether one works best with dementia. The screening VA results and algorithm decision were validated against those obtained by an optometrist performing a complete eye examination. RESULTS: Of the 150 participants, 14.7% did not respond to any optotype, while 85.3% responded to letters, 84.0% to numbers, and 66.0% to tumbling E's. The VA achieved was superior for letters. The concordance for the screening versus eye examination was >80% for VA and 90% for the algorithm. CONCLUSION: The results indicate that the tool was successful at identifying older individuals with dementia needing an eye examination.

Prevalence of Convergence Insufficiency in Parkinson's Disease.

BACKGROUND: We recently reported that convergence insufficiency (CI)-type visual symptomatology was more prevalent in participants with Parkinson's disease (PD), compared to controls. The objective of this work was to determine the prevalence of a confirmed clinical diagnosis of CI in PD, compared to controls. METHODS: Participants with (n = 80) and without (n = 80) PD were recruited and received an eye exam. Published criteria were used to arrive at a clinical diagnosis of CI. The Convergence Insufficiency Symptom Survey (CISS-15) questionnaire was administered to each participant, with a score of ≥21 being considered positive for CI symptomatology. Student t test, chi-square, or nonparametric tests at the 0.05 level were used for statistical significance. RESULTS: A total of 43.8% of participants with versus 16.3% without PD had a clinical diagnosis of CI (P ≤ 0.001). A total of 53.8% of participants with versus 18.8% without PD had scores on the CISS-15 of ≥21 (P ≤ 0.001). CONCLUSIONS: These results indicate that individuals with PD have a higher prevalence of CI and CI symptomatology than controls. These data provide evidence supporting the notion that treatment for symptomatic CI should be investigated in individuals with PD.

Cohort Profile: The Interdisciplinary Study of Inequalities in Smoking (ISIS).

The Interdisciplinary Study of Inequalities in Smoking (ISIS) is a cohort study investigating the joint effects of residents' socio-demographic characteristics and neighbourhood attributes on the social distribution of smoking in a young adult population. Smoking is a behaviour with an increasingly steep social class gradient; smoking prevalence among young adults is no longer declining at the same rate as among the rest of the population, and there is evidence of growing place-based disparities in smoking. ISIS was established to examine these pressing concerns. The ISIS sample comprises non-institutionalized individuals aged 18-25 years, who are proficient in English and/or French and who had been living at their current address in Montréal, Canada, for at least 1 year at time of first contact. Two waves of data have been collected: baseline data were collected November 2011-September 2012 (n = 2093), and a second wave of data was collected January-June 2014 (n = 1457). Data were collected from respondents using a self-administered questionnaire, developed by the research team based on sociological theory, which includes questions concerning social, economic, cultural and biological capital, and activity space as well as smoking behaviour. Data are available upon request from [katherine.frohlich@umontreal.ca].

Social disparities in children's exposure to secondhand smoke in privately owned vehicles.

INTRODUCTION: Secondhand smoke (SHS) can quickly attain high concentrations in cars, posing health risks to passengers and especially to children. This paper assesses whether there are social disparities in children's exposure to SHS in privately owned vehicles. METHODS: On weekday mornings and afternoons from September to November 2011, trained observers were stationed at 100 selected street intersections in Montreal, Canada. For each car transporting at least one passenger aged 0-15 years travelling through the intersection, observers recorded the estimated age of the youngest child in the car, whether any occupant was smoking and the licence plate number of the car. Licence plate numbers were linked to an area material deprivation index based on the postal code of the neighbourhood in which the car was registered. RESULTS: Smoking was observed in 0.7% of 20 922 cars transporting children. There was an apparent dose-response in the association between area material deprivation level and children's exposure to SHS in cars. Children travelling in cars registered in the most disadvantaged areas of Montreal were more likely to be exposed to SHS than children travelling in cars registered in the most advantaged areas (unadjusted OR=3.46, 95% CI 1.99 to 6.01). CONCLUSIONS: This study revealed social disparities in children's exposure to SHS in privately owned vehicles.

Frequency and risk factors related to smoking in cars with children present.

OBJECTIVES: Second-hand smoke (SHS) can attain high concentrations in cars. To protect children's health, nine Canadian provinces have enacted legislation prohibiting smoking in privately owned vehicles when children are present; Quebec is the only province with no such legislation. The objective of this study was to estimate the proportion of smokers in Quebec who smoke while travelling in a private vehicle in which children are present, and to compare the characteristics of smokers who do and do not smoke in cars. METHODS: In 2011-12, 754 daily smokers who recently travelled in a car with children completed a telephone survey in which they reported how frequently they smoked in a car, if there were smoking restrictions, and perceptions about the effectiveness of legislation prohibiting smoking in cars when children are present. RESULTS: Twenty-three percent of daily smokers smoked at least occasionally in their car when children were present. This proportion was higher among smokers who knew that there was no legislation in Quebec prohibiting smoking in cars, compared to smokers who believed that such legislation was already in effect (32% vs. 12%). Smokers with a university degree and those who reported that smoking was prohibited at home were less likely to expose children to SHS in cars. Most daily smokers (75%) believed that legislation would be effective. DISCUSSION: The results of this study suggest that legislation prohibiting smoking in cars is necessary to protect children from SHS, that such legislation would be effective, and that it may be relatively easy to implement.

Systematic review of vision-related quality of life questionnaires for older institutionalised seniors with dementia.

PURPOSE: In view of our interest in helping older institutionalised adults with co-existing visual and cognitive deficits, our objective was to review vision-related quality of life (VRQoL) questionnaires developed for people with dementia. METHODS: A systematic literature search was performed in seven relevant databases, limited to peer-reviewed journals published in English, French, Spanish, Italian or German languages, between 1982 and 2012. The retained VRQoL questionnaires were described. Only relevant articles that fully meet our target population and interest criteria were eligible for psychometric properties rating. RESULTS: The literature search identified 461 potentially relevant articles, from which 69 were isolated and reviewed. Eight articles presented questionnaires that were administered to older institutionalised individuals with dementia. Three VRQoL questionnaires were identified, from which only one was designed and validated for those with mild to moderate dementia and none for individuals with more advanced dementia. CONCLUSIONS: There is a pressing need to build and validate a questionnaire for assessing VRQoL in older institutionalised individuals with dementia, to provide a research tool capable of evaluating how changes in vision impact their QoL.

Attitudes toward death, dying, end-of-life palliative care, and interdisciplinary practice in long term care workers.

BACKGROUND: Besides personal and professional experiences, long term care providers' own attitudes toward death may affect the care given to dying residents. OBJECTIVES: To assess beliefs, values, and attitudes toward death, dying, palliative, and interdisciplinary care in long term care workers and identify any differences between different job categories and places of work. DESIGN: Descriptive cross-sectional survey study. SETTING: Five public long term care facilities. PARTICIPANTS: One thousand one hundred seventy volunteers, clinical managers, and all categories of residential long term care workers. MEASUREMENTS AND METHODS: An anonymous paper or electronic self-administered survey questionnaire consisting of 24 items, answered on a 4-point bipolar Likert scale. Between-group differences were compared with the analysis of variance test after adjustment for the multiple post-hoc comparisons. RESULTS: Healthcare workers had a relatively positive attitude toward more than one-half of the selected aspects of interdisciplinary practice and end-of-life palliative care for long-term residents. However, attitudes were more mixed about 10 other aspects and a higher percentage of respondents indicated negative attitudes toward them. Overall, there are significant differences between upper-level professionals and managers (registered nurses, physicians, rehabilitation staff, and clinical managers) vs the hands-on caregivers (nursing assistants, patient assistants, and volunteers) with regard to some aspects of the care of the dying. CONCLUSIONS: The results suggest that healthcare workers' attitudes need to be taken into account in long term care facilities. Patient assistants, volunteers, and nursing assistants seem most likely to above all benefit from training and support programs.

Interprofessional meetings in geriatric assessment units: a matter of care organization.

Inpatient geriatric assessment units (GAUs) exist in Quebec, Canada, to deliver comprehensive, integrated care to older vulnerable patients. Most cases should be discussed at interprofessional meetings (IMs), but research has shown this not to be so for 39% of GAU patients. Consequently, a study was undertaken to (1) describe GAU team composition and (2) identify GAU and patient characteristics associated with case discussion at IMs at least once during a patient's stay. To this end, 877 hospitalization records from 44 GAUs were reviewed. Results showed most teams were composed of attending physicians, nurses, physical and occupational therapists, dietitians and social workers; 66% included clinical pharmacists and 43% liaison nurses. Multilevel modeling showed longer length of stay to be the strongest predictor of case discussion at an IM. Case discussion was also more likely for patients admitted via in- or inter-hospital transfer rather than via the emergency department, if the GAU included a liaison nurse, and if the GAU was not located in an urban area. In summary, case discussion at an IM depended more on how and where a patient was admitted than on the patient characteristics per se, suggesting that this is a matter of care organization.

Visual acuity in institutionalized seniors with moderate to severe dementia.

OBJECTIVE: The evaluation of visual acuity (VA) in cognitively impaired older individuals may be limited by a reduced ability to cooperate or communicate. The objective of this research was to assess VA in older institutionalized individuals with cognitive impairment, including severe dementia, using various acuity charts. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS: Three groups of 30 participants each were recruited: (1) young participants; (2) older participants with no history of cognitive or communication disorders; and (3) older participants with cognitive impairment, including severe dementia, residing in long term care facilities. The Mini-Mental State Examination was performed for each institutionalized subject. VA was measured using 6 validated charts [Snellen, Teller cards, Early Treatment Diabetic Retinopathy Study (ETDRS)-letters, -numbers, -Patty Pics, -Tumbling Es] presented in random order. Nonparametric tests were used to compare VA scores between charts, after Bonferroni-Holm corrections for multiple comparisons. RESULTS: Participants in groups 1 and 2 responded to all charts. A large proportion of participants with dementia responded to all charts (n = 19), whereas only one did not respond to any chart. In group 3, VA charts with the lowest scores were the Teller cards (20/65) and Patty Pics (20/62), regardless of the level of dementia, whereas the highest VA scores were obtained with the Snellen (20/35) and ETDRS-letter (20/36) charts. Across all groups, the ETDRS-letter chart was the only one whose scores did not differ from those obtained with the standard Snellen chart. CONCLUSIONS: Visual acuity can be measured, and should at least be attempted, in older cognitively impaired individuals having a reduced ability to communicate.

Predictors of quality-of-care processes in geriatric assessment units: toward a better organizational framework.

OBJECTIVES: To identify the structural and patient characteristics associated with better care processes in older vulnerable hospitalized patients. DESIGN: Retrospective study. SETTING: Forty-four Geriatric Assessment Units (GAU). PARTICIPANTS: Patients aged 65 and older who were admitted to a GAU for a fall with trauma. MEASUREMENTS: Three care processes (comprehensiveness, informational continuity, completion of advance health care directives) assessed through chart audit; 14 patient- and 23 GAU-related characteristics obtained from hospitalization records, national databases, and GAU managers. RESULTS: A total of 877 hospitalization records were included. Final models were based on multilevel modeling using stepwise variable selection. Strongest predictors of better comprehensiveness were longer hospital length of stay (LOS), higher clinical complexity (eg, higher mortality risk), and having a geriatrician as attending physician. Comprehensiveness score increased sharply up to 3 weeks LOS and then tended to plateau. Better informational continuity was associated with more comprehensive care, higher risk of mortality, acute rather than rehabilitation care, communication with community health care professionals within 48 hours after admission, and a target LOS of 3 weeks or longer. The completion of advance directives was more likely in the presence of advanced age, higher risk of mortality, cognitive impairment, discharge to another care facility, longer LOS, university-affiliated institution, and nonurban location. CONCLUSION: In GAUs, quality-of-care processes are related to both structural and patient characteristics. Our results pointed toward an organizational framework that may help to streamline the geriatric units and better use resources, notably by narrowing the admission criteria, targeting a proper LOS, improving communication with community organizations, and making systematic completion of advance directives.

Quality-of-care processes in geriatric assessment units: principles, practice, and outcomes.

OBJECTIVES: To assess quality-of-care processes and to examine whether care processes are associated with short-term postdischarge outcomes in older vulnerable hospitalized patients. DESIGN: Retrospective study. SETTING: Forty-nine Geriatric Assessment Units. PARTICIPANTS: Patients aged 65 and older who were admitted to a Geriatric Assessment Unit for a fall with trauma. MEASUREMENTS: Three care processes (comprehensiveness, informational continuity, patient-centered care) assessed through chart audit; three-month postdischarge outcomes (emergency department visit, hospital readmission, and death) obtained from national databases. RESULTS: A total of 934 hospitalization records were included. Mean comprehensiveness and informational continuity scores were 55% ± 12% and 42% ± 16%, respectively. Items related to geriatric global assessment (eg, functional autonomy) were particularly overlooked. Patient-centered care was poorly provided, with only 24% of hospitalization records showing evidence of advance care directives and at least one patient/family meeting with the physician to discuss clinical evolution. For the three care processes, a large variability among Geriatric Assessment Units was observed. Better comprehensiveness of care was associated with lowered short-term mortality (OR = 0.73, 95% CI = 0.55-0.96, P = .023), whereas higher scores on informational continuity was associated with fewer emergency department visits (OR = 0.91, 95% CI = 0.82-1.00, P = .046), hospital readmissions (OR = 0.84, 95% CI = 0.74-0.94, P = .003), and mortality (OR = 0.72, 95% CI = 0.59-0.88, P = .002). Patient-centered care was not associated with any of the postdischarge outcomes. CONCLUSION: A large gap between geriatric care principles and practice in Geriatric Assessment Units has been observed. Our results show that improvement in care processes may be translated to decreased short-term health services use and mortality.
