Evaluation of a community paramedicine health promotion and lifestyle risk assessment program for older adults who live in social housing: a cluster randomized trial

BACKGROUND

Low-income older adults who live in subsidized housing have higher mortality and morbidity. We aimed to determine if a community paramedicine program - in which paramedics provide health care services outside of the traditional emergency response - reduced the number of ambulance calls to subsidized housing for older adults.

METHODS

We conducted an open-label pragmatic cluster-randomized controlled trial (RCT) with parallel intervention and control groups in subsidized apartment buildings for older adults. We selected 6 buildings using predefined criteria, which we then randomly assigned to intervention (Community Paramedicine at Clinic [CP@clinic] for 1 yr) or control (usual health care) using computer-generated paired randomization. CP@clinic is a paramedic-led, community-based health promotion program to prevent diabetes, cardiovascular disease and falls for residents 55 years of age and older. The primary outcome was building-level mean monthly ambulance calls. Secondary outcomes were individual-level changes in blood pressure, health behaviours and risk of diabetes assessed using the Canadian Diabetes Risk Questionnaire. We analyzed the data using generalized estimating equations and hierarchical linear modelling.

RESULTS

The 3 intervention and 3 control buildings had 455 and 637 residents, respectively. Mean monthly ambulance calls in the intervention buildings (3.11 [standard deviation (SD) 1.30] calls per 100 units/mo) was significantly lower (-0.88, 95% confidence interval [CI] -0.45 to -1.30) than in control buildings (3.99 [SD 1.17] calls per 100 units/mo), when adjusted for baseline calls and building pairs. Survey participation was 28.4% (n = 129) and 20.3% (n = 129) in the intervention and control buildings, respectively. Residents living in the intervention buildings showed significant improvement compared with those living in control buildings in quality-adjusted life years (QALYs) (mean difference 0.09, 95% CI 0.01 to 0.17) and ability to perform usual activities (odds ratio 2.6, 95% CI 1.2 to 5.8). Those who received the intervention had a significant decrease in systolic (mean change 5.0, 95% CI 1.0 to 9.0) and diastolic (mean change 4.8, 95% CI 1.9 to 7.6) blood pressure.

INTERPRETATION

A paramedic-led, community-based health promotion program (CP@clinic) significantly lowered the number of ambulance calls, improved QALYs and ability to perform usual activities, and lowered systolic blood pressure among older adults living in subsidized housing.

Effectiveness of a community paramedic-led health assessment and education initiative in a seniors' residence building: the Community Health Assessment Program through Emergency Medical Services (CHAP-EMS)

Background

Seniors living in subsidized housing have lower income, poorer health, and increased risk for cardiometabolic diseases and falls. Seniors also account for more than one third of calls to Emergency Medical Services (EMS). This study examines the effectiveness of the Community Health Assessment Program through EMS (CHAP-EMS) in reducing blood pressure, diabetes risk, and EMS calls.

Methods

Paramedics on modified duty (e.g. injured) conducted weekly, one-on-one drop-in sessions in a common area of one subsidized senior’s apartment building in Hamilton, Ontario. Paramedics assessed cardiovascular, diabetes, and fall risk, provided health education, referred participants to local resources, and encouraged participants to return to CHAP-EMS for follow-up. Reports were faxed to the family physician regularly. Blood pressure was collected throughout the one year intervention, while diabetes risk was assessed at baseline and after 6–12 months. EMS call volumes were collected from the Hamilton Paramedic Service for two years pre-intervention and one year during the intervention.

Results

There were 79 participants (mean age = 72.2 years) and 1,365 participant visits to CHAP-EMS. The majority were female (68%), high school educated or less (53%), had a family doctor (90%), history of hypertension (58%), high waist circumference (64%), high body mass index (61%), and high stress (53%). Many had low physical activity (42%), high fat intake (33%), low fruit/vegetable intake (30%), and were current smokers (29%). At baseline, 42% of participants had elevated blood pressure. Systolic blood pressure decreased significantly by the participant’s 3^rd visit to CHAP-EMS and diastolic by the 5^th visit (p < .05). At baseline, 19% of participants had diabetes; 67% of those undiagnosed had a moderate or high risk based on the Canadian Diabetes Risk (CANRISK) assessment. 15% of participants dropped one CANRISK category (e.g. high to moderate) during the intervention. EMS call volume decreased 25% during the intervention compared to the previous two years.

Conclusions

CHAP-EMS was associated with a reduction in emergency calls and participant blood pressure and a tendency towards lowered diabetes risk after one year of implementation within a low income subsidized housing building with a history of high EMS calls.

Assessing health literacy among older adults living in subsidized housing: a cross-sectional study

OBJECTIVES

This study aimed to assess functional health literacy levels among older adults living in subsidized housing in Hamilton, Ontario, and to assess the relationships between health literacy and other important health indicators, such as education level, age, ethnicity, body mass index (BMI), and self-reported health status.

METHODS

Older adults (n = 237) living in subsidized housing buildings in Hamilton, ON, were assessed using the NVS-UK as a measure of functional health literacy in addition to a health indicator questionnaire through structured interview. Health literacy levels were analyzed using descriptive statistics and logistic regression to determine relationships between health literacy levels and other health indicators.

RESULTS

Participants' mean age was 73 years, 67% were female, 70% were not educated beyond high school, and 91% were white. Over 82% of participants had below adequate health literacy levels using the NVS-UK. Multivariable logistic regression revealed significant relationships between functional health literacy and BMI, education level, and pain and discomfort levels. No significant relationships were found between health literacy level and age group, anxiety and depression levels, CANRISK (Diabetes risk) score, gender, marital status, mobility issues, self-care issues, self-reported health status, or performance of usual activities.

CONCLUSIONS

As the population of older adults continues to grow, the appropriate resources must be available to both improve and support the health literacy level of the population. Future health research should gather information on the health literacy levels of target populations to ensure more equitable health service. This research provides a significant opportunity to better understand populations with health literacy barriers.

Rationale and methods of a multicentre randomised controlled trial of the effectiveness of a Community Health Assessment Programme with Emergency Medical Services (CHAP-EMS) implemented on residents aged 55 years and older in subsidised seniors' housing buildings in Ontario, Canada

INTRODUCTION

Chronic diseases and falls substantially contribute to morbidity/mortality among seniors, causing this population to frequently seek emergency medical care. Research suggests the paramedic role can be successfully expanded to include community-based health promotion and prevention. This study implements a community paramedicine programme targeting seniors in subsidised housing, a high-risk population and frequent users of emergency medical services (EMS). The aims are to reduce EMS calls, improve health outcomes and healthcare utilisation.

METHODS/ANALYSIS

This is a pragmatic clustered randomised control trial in four communities across Ontario, Canada. Within each, four to eight seniors' apartment buildings will be paired and within each pair one building will be randomly assigned to receive the Community Health Assessment Programme through EMS (CHAP-EMS) intervention, while the other building receives no intervention. During the 1-year intervention, paramedics will run weekly sessions in a common area of the building, assessing risk factors for cardiovascular disease, diabetes and falls; providing health education and referrals to community programmes; and communicating results to the participant's primary physician. The primary outcomes are rate of emergency calls per 100 residents, change in blood pressure and change in Canadian Diabetes Risk (CANRISK) score, as collected by the local EMS and study databases. The secondary outcomes are change in health behaviours, measured using a preintervention and postintervention survey and healthcare utilisation, available through administrative databases. Analysis will mainly consist of descriptive statistics and generalised estimating equations, including subgroup cluster analysis.

ETHICS/DISSEMINATION

This study is approved by the Hamilton Integrated Research Ethics Board and will follow the Tri-Council Policy Statement. Findings will be disseminated through reports to local stakeholders, publication in peer-reviewed journals and conference presentations.

Risk of falls and fear of falling in older adults residing in public housing in Ontario, Canada: findings from a multisite observational study

Background

Falls in older adults is a widely researched topic. However, older adults residing in public housing are a vulnerable population that may have unique risk factors for falls. This study aims to describe the prevalence and risk factors for falls, fear of falling, and seeking medical attending for falls in this population.

Methods

Sociodemographic and health-related data was collected as part of a community-based health assessment program with older adults in public housing. Three pre-screening questions identified individuals at potential risk for falls; individuals who screened positive performed the objective Timed Up and Go (TUG) test. Logistic regression was used to evaluate risk factors for four outcome variables: falls in the past year, seeking medical attention for falls, fear of falling, and objectively measured fall risk via TUG test.

Results

A total of 595 participants were evaluated, of which the majority were female (81.3%), white (86.7%), did not have a high school diploma (50.0%), and reported problems in mobility (56.2%). The prevalence of falls in the past year was 34.5%, seeking medical attention for falls was 20.2% and fear of falling was 38.8%. The TUG test was completed by 257 participants. Notably, males had significantly reduced odds of seeking medical attention for a fall (OR = 0.50, 95%CI 0.25–0.98) and having a fear of falling (OR = 0.42, 95%CI 0.24–0.76); daily fruit and vegetable consumption was associated with decreased odds of having a fall in the past year (OR = 0.55, 95%CI 0.37–0.83), and alcohol consumption was associated with increased odds of fear of falling (OR = 1.72, 95%CI 1.03–2.88).

Conclusion

Older adults residing in public housing have unique risk factors associated with social determinants of health, such as low fruit and vegetable consumption, which may increase their risk for falls. The findings of this study can be used to inform falls interventions for this population and identify areas for further research.

Poverty and food insecurity of older adults living in social housing in Ontario: a cross-sectional study

BACKGROUND

Poverty and food insecurity have been linked to poor health and morbidity, especially in older adults. Housing is recognized as a social determinant of health, and very little is known about subjective poverty and food insecurity in the marginalized population of older adults living in subsidized social housing. We sought to understand poverty and food insecurity, as well as the risk factors associated with both outcomes, in older adults living in social housing in Ontario.

METHODS

This was a cross-sectional study using data collected from the Community Paramedicine at Clinic (CP@clinic) program. A total of 806 adult participants residing in designated seniors' or mixed family-seniors' social housing buildings attended CP@clinic within 14 communities across Ontario, Canada.

RESULTS

The proportion of older adults reporting poverty and food insecurity were 14.9 and 5.1%, respectively. Statistically significant risk factors associated with poverty were being a smoker (AOR = 2.38, 95% CI: 1.23-4.62), self-reporting feeling extremely anxious and/or depressed (AOR = 3.39, 95% CI: 1.34-8.62), and being food insecure (AOR = 23.52, 95% CI: 8.75-63.22). Statistically significant risk factors associated with food insecurity were being underweight (AOR = 19.79, 95% CI: 1.91-204.80) and self-reporting experiencing poverty (AOR = 23.87, 95% CI: 8.78-64.90). In those who self-reported being food secure, the dietary habits reported were consistent with a poor diet.

CONCLUSION

The poverty rate was lower than expected which could be related to the surrounding environment and perceptions around wealth. Food insecurity was approximately twice that of the general population of older adults in Canada, which could be related to inaccessibility and increased barriers to healthy foods. For those who reported being food secure, dietary habits were considered poor. While social housing may function as a financial benefit and reduce perceived poverty, future interventions are needed to improve the quality of diet consumed by this vulnerable population.

Reducing 9-1-1 Emergency Medical Service Calls By Implementing A Community Paramedicine Program For Vulnerable Older Adults In Public Housing In Canada: A Multi-Site Cluster Randomized Controlled Trial

Objective: Older adults account for 38-48% of emergency medical service (EMS) calls, have more chronic diseases, and those with low income have lower quality of life. Mobile integrated health and community paramedicine may help address these health inequalities and reduce EMS calls. This study examines the effectiveness of the Community Paramedicine at Clinic (CP@clinic) program in decreasing EMS calls and improving health outcomes in low-income older adults. Methods: This was an open-label, pragmatic, cluster-randomized controlled trial conducted within subsidized public housing buildings for older adults in 5 paramedic services across Ontario, Canada. A total of 30 apartment buildings were eligible (>50 units, >60% of units occupied by older adults, unique postal code, available match for pairing). Paired buildings were randomly allocated to intervention (CP@clinic for one year) or control (usual care) via computer-generated randomization. The CP@clinic intervention is a community-based, paramedic-led, health promotion and disease prevention program held weekly in building common rooms. CP@clinic includes risk assessment with validated tools, decision support, health promotion, referrals to resources, and reports back to family doctors. All residents could participate, but only older adults (55 years and older) were included in analyses. The primary outcome was building-level EMS calls from paramedic service databases. Secondary outcomes were individual-level changes in chronic disease risk factors and quality-adjusted-life-years (QALYs). Data were analyzed using Generalized Estimating Equations to account for clustering by sites. Results: Intention-to-treat analysis showed no significant difference in EMS calls (mean difference = -0.37/100 apartment units/month, 95%CI: -0.98 to 0.24). Sensitivity analysis excluding data from 2 building pairs with eligibility changes after intervention initiation revealed a significant difference in EMS calls in favor of the intervention buildings (mean difference = -0.90/100 apartment units/month, 95%CI: -1.54 to -0.26). At the individual level, there was a significant QALY increase (mean difference = 0.06, 95%CI: 0.02 to 0.10) and blood pressure decrease (systolic mean change = 3.65 mmHg, 95%CI: 2.37 to 4.94; diastolic mean change = 2.03 mmHg, 95%CI: 1.00 to 3.06). Conclusions: CP@clinic showed a significant decrease in EMS calls, decrease in BP, and improvement in QALYs among older adults in subsidizing public housing, suggesting this simple program should be replicated in other communities with public housing.

Development of a community health and wellness pilot in a subsidised seniors' apartment building in Hamilton, Ontario: Community Health Awareness Program delivered by Emergency Medical Services (CHAP-EMS)

BACKGROUND

Older adults have higher risk of developing cardiovascular disease, diabetes and falls, leading to costly emergency medical service (EMS) calls and emergency room visits. We developed the Community Health Assessment Program through EMS (CHAP-EMS) that focuses on health promotion/prevention of hypertension and diabetes, links with primary care practitioners, targets seniors living in subsidized housing, and aims to reduce morbidity from these conditions, thereby reducing EMS calls. In this pilot study, we evaluated the feasibility of implementing the CHAP-EMS, attendance rates, prevalence of high blood pressure and cardiovascular risk factors.

METHODS

In this pilot study the CHAP-EMS was implemented in the intervention site over a 12 month period. BP, lifestyle, cardiovascular risk and EMS call rates were collected and descriptive analyses performed. Participants were residents (low income seniors) of a subsidized housing complex in Hamilton, Ontario. Two paramedics provided once-weekly sessions, measuring BP, assessing diabetes/lifestyle risk (CANRISK questionnaire) and discussed prevention/local wellness activities in the intervention site. Follow up was invited.

RESULTS

A total of 1365 visits with 79 unique participants occurred; 48 (25.2%) visited at least twice; mean age was 72.2; 87.2% were 65 years of age and older and 68.1% were female; 90.3% had a family doctor. Overall, 45.2% had elevated BP initially from the total; 50.0% of participants previously diagnosed with hypertension had elevated BP while 33.3% not previously diagnosed had elevated BP. Almost 1 in 5 (19.4%) had diabetes; 66.7% had moderate to high risk of developing diabetes.

CONCLUSION

This pilot study indicates that CHAP-EMS is a feasible program that could have impact on BP, lifestyle factors, diabetes risk and EMS calls in the buildings in which it was implemented.

Cost-effectiveness analysis of a community paramedicine programme for low-income seniors living in subsidised housing: the community paramedicine at clinic programme (CP@clinic)

OBJECTIVES

To evaluate the cost-effectiveness of the Community Paramedicine at Clinic (CP@clinic) programme compared with usual care in seniors residing in subsidised housing.

DESIGN

A cost-utility analysis was conducted within a large pragmatic cluster randomised controlled trial (RCT). Subsidised housing buildings were matched by sociodemographics and location (rural/urban), and allocated to intervention (CP@clinic for 1 year) or control (usual care) via computer-assisted paired randomisation.

SETTING

Thirty-two subsidised seniors' housing buildings in Ontario.

PARTICIPANTS

Building residents 55 years and older.

INTERVENTION

CP@clinic is a weekly community paramedic-led, chronic disease prevention and health promotion programme in the building common areas. CP@clinic is free to residents and includes risk assessments, referrals to resources, and reports back to family physicians.

OUTCOME MEASURES

Quality-adjusted life years (QALYs) gained, measured with EQ-5D-3L. QALYs were estimated using area-under-the curve over the 1-year intervention, controlling for preintervention utility scores and building pairings. Programme cost data were collected before and during implementation. Costs associated with emergency medical services (EMS) use were estimated. An incremental cost effectiveness ratio (ICER) based on incremental costs and health outcomes between groups was calculated. Probabilistic sensitivity analysis using bootstrapping was performed.

RESULTS

The RCT included 1461 residents; 146 and 125 seniors completed the EQ-5D-3L in intervention and control buildings, respectively. There was a significant adjusted mean QALY gain of 0.03 (95% CI 0.01 to 0.05) for the intervention group. Total programme cost for implementing in five communities was $C128 462 and the reduction in EMS calls avoided an estimated $C256 583. The ICER was $C2933/QALY (bootstrapped mean ICER with Fieller's 95% CI was $4850 ($2246 to $12 396)) but could be even more cost effective after accounting for the EMS call reduction.

CONCLUSION

The CP@clinic ICER was well below the commonly used Canadian cost-utility threshold of $C50 000. CP@clinic scale-up across subsidised housing is feasible and could result in better health-related quality-of-life and reduced EMS use in low-income seniors.

Rationale and methods of an Evaluation of the Effectiveness of the Community Paramedicine at Home (CP@home) program for frequent users of emergency medical services in multiple Ontario regions: a study protocol for a randomized controlled trial

BACKGROUND

Frequent users of emergency medical services for issues that could be more appropriately managed through non-urgent care deplete the limited resources of the health-care system. Community paramedicine is an emerging field that extends the role of paramedics beyond the traditional emergency response. The goal of the current study is to evaluate the impact of a community paramedicine home-visit intervention with frequent users on reducing ambulance calls, hospital visits, and admissions. The study will also provide a cross-sectional description of the characteristics of frequent users of emergency medical services.

METHODS/DESIGN

An open-label, pragmatic, randomized controlled trial with parallel intervention and control groups will be conducted in four paramedic services in Ontario. The sample size has been calculated as 261 per group for a 25% reduction in ambulance calls. Eligible participants will be frequent callers (three or more calls in 6 months), individuals who call for at least one lift assist, or individuals referred to the program by a paramedic. Individuals will be randomly allocated to receive either the Community Paramedicine at Home (CP@home) program intervention or their usual care (control). Intervention participants will receive up to three visits from a community paramedic, who will conduct health risk assessments, provide health promotion and education, provide referrals to local resources, and fax reports back to the family physician. Data will be collected from administrative databases (e.g., paramedic services), a custom CP@home program database, participant surveys, and key informant interviews. An intention-to-treat analysis will be conducted, including descriptive statistics and multi-level modeling to find factors predictive of primary and secondary outcomes. A thematic analysis will be used to analyze the qualitative outcomes. An economic analysis will consider the cost-effectiveness of the program.

DISCUSSION

CP@home has the potential to reduce the health-care system burden significantly by targeting current frequent users of emergency medical services. By targeting this population, CP@home aims to decrease ambulance calls and emergency department visits, reducing health-care costs and improving the quality of life of a vulnerable population. If successful, CP@home will inform the development of community paramedicine policies and the expanding role of paramedics in regions across Canada.

Development of the Health Awareness and Behaviour Tool (HABiT): reliability and suitability for a Canadian older adult population

BACKGROUND

Determining the effectiveness of community-based health promotion and disease prevention programs requires an appropriate data collection tool. This study aimed to develop a comprehensive health questionnaire for older adults, called the HABiT, and evaluate its reliability, content validity, and face validity in assessing individual health-related items (e.g., health status, healthcare utilization) and five specific scales: knowledge, current health behaviors (risk factors), health-related quality of life (HRQoL), perceived risk and understanding, and self-efficacy.

METHODS

Iterative survey development and evaluation of its psychometric properties in a convenience sample of 28 older adults (≥ 55 years old), half from a low-income population. Following item generation, the questionnaire was assessed for content validity (expert panel), face validity (participant feedback), internal consistency of each scale (Cronbach's alpha), and test-retest reliability for each item and scale (Pearson's r and phi correlations, as appropriate).

RESULTS

Questions were drawn from 15 sources, but primarily three surveys: Canadian Community Health Survey, Canadian Diabetes Risk Questionnaire (CANRISK), and a survey by the Canadian Hypertension Education Program. Expert consensus was attained for item inclusion and representation of the desired constructs. Participants completing the questionnaire deemed the questions to be clear and appropriate. Test-retest reliability for many individual items was moderate-to-high, with some exceptions for items that can reasonably change in a short period (e.g., perceived day-to-day stress). Of the five potential scales evaluated, two had acceptable internal consistency (Cronbach's alpha ≥ 0.60) and a subset of one scale also had acceptable internal consistency. Test-retest reliability was high (correlation ≥ 0.80) for all scales and sub-scales.

CONCLUSIONS

The HABiT is a reliable and suitable comprehensive tool with content and face validity that can be used to evaluate health promotion and chronic disease prevention programs in older adults, including low-income older adults. Some noted limitations are discussed. Data collected using this tool also provides a diabetes risk score, health literacy score, and quality-adjusted life years (QALYs) for economic analysis.

Subjective social isolation or loneliness in older adults residing in social housing in Ontario: a cross-sectional study

BACKGROUND

Older adults face greater risk of social isolation, but the extent of social isolation among low-income older adults living in social housing is unknown. This study aims to explore the rate of, and risk factors contributing to, subjective social isolation or loneliness among older adults in social housing.

METHODS

We conducted a cross-sectional study of data collected from a community program held in the common rooms of 55 social housing buildings in 14 communities across Ontario, Canada, from May 2018 to April 2019. Participants were program attendees aged 55 years and older who resided in the buildings. Program implementers assessed social isolation using the 3-Item Loneliness Scale from the University of California, Los Angeles and risk factors using common primary care screening tools. We extracted data for this study from the program database. We compared the rate of social isolation to Canadian Community Health Survey data using a 1-sample χ² test, and evaluated associations between risk factors and social isolation using univariate and multivariate logistic regressions.

RESULTS

We included 806 residents in 30 buildings for older adults and 25 mixed-tenant buildings. Based on the 3-Item UCLA Loneliness Scale, 161 (20.0%) of the 806 participants were socially isolated. For those aged 65 and older, the rate of social isolation was nearly twice that observed in the same age group of the general population (36.1% v. 19.6%; p < 0.001). Risk factors were age (65-84 yr v. 55-64 yr adjusted odds ratio [OR] 1.99, 95% confidence interval [CI] 1.01-3.93), alcohol consumption (adjusted OR 2.45, 95% CI 1.09-5.54), anxiety or depression (adjusted OR 6.05, 95% CI 3.65-10.03) and income insecurity (adjusted OR 2.10, 95% CI 1.24-3.53). Protective factors were having at least 1 chronic cardiometabolic disease (adjusted OR 0.44, 95% CI 0.24-0.80), being physically active (adjusted OR 0.47, 95% CI 0.30-0.73) and having good to excellent general health (adjusted OR 0.60, 95% CI 0.39-0.90).

INTERPRETATION

The high rate of social isolation in low-income older adults living in social housing compared with the general population is concerning. Structural barriers could prevent engagement in social activities or maintenance of social support, especially for older adults with income insecurity and anxiety or depression; interventions are needed to reduce subjective social isolation in this population.

Feasibility of implementing a community cardiovascular health promotion program with paramedics and volunteers in a South Asian population

BACKGROUND

The South Asian population in Canada is growing and has elevated risk of cardiovascular disease and diabetes. This study sought to adapt an evidence-based community risk assessment and health promotion program for a South Asian community with a large proportion of recent immigrants. The aims were to assess the feasibility of implementing this program and also to describe the rates of cardiometabolic risk factors observed in this sample population.

METHODS

This was a feasibility study adapting and implementing the Community Paramedicine at Clinic (CP@clinic) program for a South Asian population in an urban Canadian community for 14 months. CP@clinic is a free, drop-in chronic disease prevention and health promotion program implemented by paramedics who provide health assessments, health education, referrals and reports to family doctors. All adults attending the recreation centre and temple where CP@clinic was implemented were eligible. Volunteers provided Hindi, Punjabi and Urdu translation. The primary outcome of feasibility was evaluated using quantitative process measures and a qualitative key informant interview. For the secondary outcome of cardiometabolic risk factor, data were collected through the CP@clinic program risk assessments and descriptively analyzed.

RESULTS

There were 26 CP@clinic sessions held and 71 participants, predominantly male (56.3-84.6%) and South Asian (87.3-92.3%). There was limited participation at the recreation centre (n = 19) but CP@clinic was well-attended when relocated to the local Sikh temple (n = 52). Having the volunteer translators was critical to the paramedics being able to collect the full risk factor data and there were some challenges with ensuring enough volunteers were available to staff each session; as a result, there were missing risk factor data for many participants. In the 26 participants with complete or almost complete risk factor data, 46.5% had elevated BP, 42.3% had moderate/high risk of developing diabetes, and 65.4% had an indicator of cardiometabolic disease.

CONCLUSION

Implementing CP@clinic in places of worship is a feasible approach to adapting the program for the South Asian population, however having a funded translator in addition to the volunteers would improve the program. Also, there is substantial opportunity for addressing cardiometabolic risk factors in this population using CP@clinic.

Design and rationale for a pragmatic cluster randomized trial of the Cardiovascular Health Awareness Program (CHAP) for social housing residents in Ontario and Quebec, Canada

BACKGROUND

The Cardiovascular Health Awareness Program (CHAP) uses volunteers to provide cardiovascular disease (CVD) and diabetes screening in a community setting, referrals to primary care providers, and locally available programs targeting lifestyle modification. CHAP has been adapted to target older adults residing in social housing, a vulnerable segment of the population. Older adults living in social housing report poorer health status and have a higher burden of a multitude of chronic illnesses, such as CVD and diabetes. The study objective is to evaluate whether there is a reduction in unplanned CVD-related Emergency Department (ED) visits and hospital admissions among residents of social seniors' housing buildings receiving the CHAP program for 1 year compared to residents in matched buildings not receiving the program.

METHODS/DESIGN

This is a pragmatic, cluster randomized controlled trial in community-based social (subsidized) housing buildings in Ontario and Quebec. All residents of 14 matched pairs (intervention/control) of apartment buildings will be included. Buildings with 50-200 apartment units with the majority of residents aged 55+ and a unique postal code are included. All individuals residing within the buildings at the start of the intervention period are included (intention to treat, open cohort). The intervention instrument consists of CHAP screens for high blood pressure using automated blood pressure monitors and for diabetes using the Canadian Diabetes Risk (CANRISK) assessment tool. Monthly drop-in sessions for screening/monitoring are held within a common area of the building. Group health education sessions are also held monthly. Reports are sent to family doctors, and attendees are encouraged to visit their family doctor. The primary outcome measure is monthly CVD-related ED visits and hospitalizations over a 1-year period post randomization. Secondary outcomes are all ED visits, hospitalizations, quality of life, cost-effectiveness, and participant experience.

DISCUSSION

It is anticipated that CVD-related ED visits and hospitalizations will decrease in the intervention buildings. Using the volunteer-led CHAP program, there is significant opportunity to improve the health of older adults in social housing.

Type 2 Diabetes Risk in Older Adults Living in Social Housing: A Cross-Sectional Study

OBJECTIVES

This study aimed to describe the risk of developing diabetes and the probable prevalence of diabetes and prediabetes in residents of subsidized or social housing who were 55 years of age or older.

METHODS

We conducted a cross-sectional study using data collected from an ongoing community health program in social housing buildings-the Community Paramedicine at Clinic (CP@clinic) program. Community paramedics staffing the CP@clinic program conducted lifestyle-related modifiable risk factor assessments of participating social housing residents who were 55 years of age or older. The Canadian Diabetes risk assessment (CANRISK) tool was administered to all participants, and those with moderate-to-high risk of developing diabetes were asked to return for a fasting capillary blood glucose (CBG) measurement. Data were collected from program participants who attended the sessions between December 2014 and May 2018.

RESULTS

There were 728 participants. Most were women (80.5%), aged 65 to 84 (68.1%), white (85.4%) and educated to the high school level or less (69.2%). At baseline, 71.3% were identified as having overweight or obesity, and 12.5% were diagnosed with diabetes. Of participants not diagnosed with diabetes (N=632), 66.6% were at high risk of developing diabetes, and 30.1% were categorized as moderate risk. The CBG assessments showed that 37.7% (N=158) of those with high risk and 22.0% (N=42) of those with moderate risk had blood glucose readings indicating impaired fasting glucose or probable diabetes.

CONCLUSIONS

This study shows that 96.7% of low-income older adults in social housing buildings had moderate-to-high risk of developing diabetes and that the probable prevalence of undiagnosed prediabetes and diabetes was 32.0%.

Challenges in recruiting frequent users of ambulance services for a community paramedic home visit program

BACKGROUND

The Community Paramedicine at Home (CP@home) program is a health promotion program where community paramedics conduct risk assessments with frequent 9-1-1 callers in their homes, with a goal of reducing the frequency of 9-1-1 calls in this vulnerable population. The effectiveness of the CP@home program was investigated through a community-based RCT conducted in four regions in Ontario, Canada. The purpose of this current recruitment study is to examine the challenges met when recruiting for a community randomized control trial on high frequency 9-1-1 callers.

METHODS

Eligible participants were recruited from one of four regions participating in the CP@home program and were randomly assigned to an intervention group (n = 1142) or control group (n = 1142). Data were collected during the recruitment process from the administrative database of the four paramedic services. Whether they live alone, their parental ethnicity, age, reason for calling 9-1-1, reason for not participating, contact method, and whether they were successfully contacted were recorded. Statistical significance was calculated using the Chi-Squared Test and Fisher's Exact Test to evaluate the effectiveness of the recruitment methods used to enroll eligible participants in the CP@home Program.

RESULTS

Of the people who were contacted, 48.0% answered their phone when called and 53.9% answered their door when a home visit was attempted. In Total, 110 (33.1%) of people where a contact attempt was successful participated in the CP@home program. Most participants were over the age of 65, even though people as young as 18 were contacted. Older adults who called 9-1-1 for a lift assist were more likely to participate, compared to any other individual reason recorded, and were most often recruited through a home visit.

CONCLUSIONS

This recruitment analysis successfully describes the challenges experienced by researchers when recruiting frequent 9-1-1 callers, which are considered a hard-to-reach population. The differences in age, contact method, and reason for calling 9-1-1 amongst people contacted and participants should be considered when recruiting this population for future research.

Development and evaluation of a low-cost database solution for the Community Paramedicine at Clinic (CP@clinic) database

The Community Paramedicine at Clinic (CP@clinic) program is a community program that utilizes community paramedics to support older adults in assessing their risk factors, managing their chronic conditions, and linking them to community resources. The aim of this project is to design a low-cost, portable, secure, user-friendly database for CP@clinic sessions and pilot test the database with paramedics and older adult volunteers. The CP@clinic program database using the Microsoft Access software was first developed through consultation with the CP@clinic research team. Next, the database was pilot tested with two sets of older adults and one set of paramedics to assess user experience. Volunteers completed a survey regarding their perceptions of the level of difficulty when using the database. A computer-based database was the best option as it provided flexibility while reducing costs. The final database should perform calculations and summarize risk assessment data, provide recommended resources, generate automated reports, capture changes in medical and medication history, and ensure that the sensitive information is secure. During pilot testing, the older adult participants and the paramedics indicated that the database was easy to use. This low-cost, user-friendly and secure database captures initial and follow-up data, incorporates algorithms that guide the paramedics, and calculates risk factor scores for the participants. This solution to a healthcare database is translatable to other health research studies in which ongoing patient data is collected electronically and longitudinally.

A comparison of self-reported chronic disease, health awareness and behaviours in social housing residents: cross-sectional study of communities in Ontario and Quebec

OBJECTIVE

Social housing programs are integral to making housing more affordable to Canadian seniors living in poverty. Although the programs are similar across Canada, there may be inter-provincial differences among the health of residents that could guide the development of interventions. This study explores the health of low-income seniors living in social housing in Quebec and compares it with previously reported data from Ontario.

RESULTS

80 responses were obtained in Quebec to compare with the previously reported Ontario data (n = 599) for a total of 679 responses. More Ontario residents had access to a family doctor (p < 0.001). Quebec residents experienced less problems with self-care (p = 0.017) and less mobility issues (p = 0.052). The visual analog scale for overall health state was similar in both provinces (mean = 67.36 in Ontario and 69.23 in Quebec). Residents in Quebec smoked more cigarettes per day (p = 0.009). More residents in Ontario participated in moderate physical activity (p = 0.09), however, they also spent more time per day on the computer (p = 0.006).

Effectiveness of the community paramedicine at home (CP@home) program for frequent users of emergency medical services in Ontario: a randomized controlled trial

OBJECTIVE

To evaluate the impact of the Community Paramedicine at Home (CP@home) program, a community paramedicine home-visit intervention, on reducing emergency medical services (EMS) calls among frequent users.

DESIGN

A 6-month, open-label, pragmatic, randomized controlled trial with parallel intervention and control arms. An online automated platform (randomizer.org) was used to randomly allocate participants using a 1:1 allocation sequence.

SETTING

In homes of frequent EMS users in four paramedic services and regions across Ontario, Canada.

PARTICIPANTS

Eligible participants were frequent callers (≥ 3 EMS calls within six months and ≥ 1 EMS call within the previous month), or had ≥ 1 lift assist call within the previous month, or were referred by paramedics.

INTERVENTION

Community paramedics conducted risk assessments, provided health education, referred appropriate resources, and reported to family physicians for up to three home visits. The control arm received usual care.

PRIMARY OUTCOME MEASURE

EMS calls in 6 months during intervention.

RESULTS

Two thousand two hundred eighty four eligible participants were randomly allocated to the intervention and control groups, with 265 participants lost to follow-up due to inability to retrieve participant records from EMS databases. There were 1025 intervention participants (52.7% female, mean age 69.65 years [standard deviation (SD) = 19.98]) and 994 control participants (52.0% female, mean age 69.78 years [SD = 19.09]). In the post-intervention intention-to-treat analysis (zero-inflated negative binomial regression), the EMS call rate was not significantly lower in the intervention group compared to the control group (incidence rate ratio [IRR] = 0.88, 95% confidence interval [CI]: 0.76, 1.01). In the subgroup analysis, the intervention had a significant effect in the lift assist caller subgroup (IRR = 0.73, 95% CI: 0.58, 0.92), but no significant effect among the frequent caller subgroup (IRR = 0.97, 95% CI: 0.82, 1.14). The sensitivity analyses found a similar association for the lift assist caller subgroup. There was a significant subgroup effect (p-value for interaction < 0.01).

CONCLUSIONS

CP@home had a significant impact on reducing EMS calls for those with a lift assist call but not for the overall sample. This program filled a healthcare gap by shifting primary care delivery, which could reduce the disproportionate number of EMS calls, thus reducing healthcare costs.

Older adults in social housing: A systemically vulnerable population that needs to be prioritized

Older adults living in social housing are a vulnerable population with unique health challenges that often lead to poor health outcomes and high emergency service utilization. However, the needs of this population are frequently overlooked. This policy note describes the characteristics of older adults living in social housing in Canada and discusses why they are a vulnerable, underserved population in need of immediate attention and priority. Older adults in social housing have higher rates of chronic disease, lower quality of life, and lower health literacy and face challenges caused by various compounding social determinants of health. There is a large gap in research and tailored interventions focusing on this population. Based on these findings, the authors highlight the need for the allocation of resources to support this growing population, including dedicated funding, research, and programming. Proactively addressing the issues that exist in the health and social care of this high-needs population will also have larger implications for reducing healthcare system burden.

COVID-19 and social care screening for older adults in social housing: a CP@clinic adaptation

BACKGROUND

COVID-19 has changed healthcare access and delivery, especially impacting older adults. The Community Paramedicine at Clinic (CP@clinic) program is a chronic disease prevention, management, and health promotion program for community-dwelling low-income older adults. We investigated a telephone-based CP@clinic program adaptation during the pandemic.

METHODS

Community paramedics delivered CP@clinic via telephone to residents of 36 social housing buildings. They conducted screening for COVID-19, emergency preparedness, and social health factors. Community paramedics provided education on staying safe, self-isolating, self-monitoring, and preparing for pandemics using governmental infographics. Descriptive analysis was conducted on assessments completed between March and June 2020. Paramedic documentation was thematically analyzed to identify common themes.

RESULTS

All 191 participants had ≥ 1 telephone visit and 34.6% had ≥ 2 telephone visits, 82.8% were aged 65 years and older, 30.9% had internet access, and 57.9% had cable TV (limiting exposure to COVID-19 information). The CP@clinic program infrastructure provided a platform for paramedics to swiftly contact many vulnerable older adults to screen for COVID-19, educate on safe practices, and facilitate healthcare access. One-quarter of participants screened positive for social isolation. Thematic analysis described participants' experiences adapting to daily life in the pandemic, emotional experience during the pandemic, and paramedics supporting participants during the pandemic.

CONCLUSIONS

Public health interventions are needed for low-income or hard-to-reach older adults, especially during pandemics. Community paramedics were able to support vulnerable older adults living in social housing through the unique CP@clinic adaptation. This innovative program delivery increased vulnerable populations' access to public health services and information at a time of great health need.

Adapting the Community Paramedicine at Clinic (CP@clinic) program to a remote northern first nation community: a qualitative study of community members' and local health care providers' views

The views of community Elders and health care providers in a rural remote First Nation community in Ontario, Canada on their health care landscape and adapting the Community Paramedicine at Clinic (CP@clinic) Program to their community are presented. Key informant interviews took place between September 2020 and March 2021, and were thematically analysed using the Framework Hierarchical Analysis. There were seven themes that emerged with many subthemes: available services in the community, health care access, health challenges in community, causes of frailty, health care and community appreciations, community-specific benefits of CP@clinic, and CP@clinic program considerations for adaptation. CP@clinic program considerations for adaptation included defining the role of CP, refining referral processes to capture the target population, advertising and promoting, ensuring community awareness, determining clinic setting and composition, focusing on advocacy and timely continuity, adding to the program through time, managing resistance, engaging community and partners, deploying cultural training and language accommodations, leveraging community assets, and ensuring sustainability. Focusing on continuity, engagement, and leveraging available resources may support the success of the CP@clinic program implementation. Findings from this study may be useful to other underserved communities in Canada seeking health programming.

SARS-CoV-2 testing, test positivity and vaccination in social housing residents compared with the general population: a retrospective population-based cohort study

BACKGROUND

The consideration of unique social housing needs has largely been absent from the COVID-19 response, particularly in tailoring strategies to improve access to testing and vaccine uptake among vulnerable and high-risk populations in Ontario. Given the growing population of social housing residents, this study aimed to compare SARS-CoV-2 testing, positivity, and vaccination rates in a social housing population with those in a general population cohort in Ontario, Canada.

METHODS

This population-based cohort study used administrative health data from Ontario to examine SARS-CoV-2 testing, positivity and vaccination rates in social housing residents compared with the general population from 1 January 2020 to 31 December 2021. All comparisons were unadjusted, stratified by sex and age and evaluated using standardised differences.

RESULTS

The rates of SARS-CoV-2 PCR testing were lower among younger age groups and higher among older adults within the social housing cohort, compared with the general population cohort. SARS-CoV-2 test positivity was higher in social housing than in the general population among individuals aged 60-79 years (7.9% vs 5.3%, respectively) and 80 years and older (12.0% vs 7.9%, respectively). Overall, 34.3% of social housing residents were fully vaccinated, compared with 29.6% of the general population cohort. However, a smaller proportion of social housing residents had received a booster vaccine (36.7%) compared with the general population (52.4%).

CONCLUSION

Improved and targeted outreach strategies are needed to increase the uptake of COVID-19 booster vaccines among social housing residents.

Health knowledge and self-efficacy to make health behaviour changes: a survey of older adults living in Ontario social housing

BACKGROUND

Older adults living in social housing are a vulnerable population facing unique challenges with health literacy and chronic disease self-management. We investigated this population's knowledge of cardiovascular disease and diabetes mellitus, and self-efficacy to make health behaviour changes (for example, physical activity). This study characterized the relationship between knowledge of health risk factors and self-efficacy to improve health behaviours, in order to determine the potential for future interventions to improve these traits.

METHODS

A cross-sectional study (health behaviour survey) with adults ages 55+ (n = 599) from 16 social housing buildings across five Ontario communities. Descriptive analyses conducted for demographics, cardiovascular disease and diabetes knowledge, and self-efficacy. Subgroup analyses for high-risk groups were performed. Multivariate logistic regressions models were used to evaluate associations of self-efficacy outcomes with multiple factors.

RESULTS

Majority were female (75.6%), white (89.4%), and completed high school or less (68.7%). Some chronic disease subgroups had higher knowledge for those conditions. Significant (p < 0.05) associations were observed between self-efficacy to increase physical activity and knowledge, intent to change, and being currently active; self-efficacy to increase fruit/vegetable intake and younger age, knowledge, and intent to change; self-efficacy to reduce alcohol and older age; self-efficacy to reduce smoking and intent to change, ability to handle crises, lower average number of cigarettes smoked daily, and less frequent problems with usual activities; self-efficacy to reduce stress and ability to handle crises.

CONCLUSIONS

Those with chronic diseases had greater knowledge about chronic disease. Those with greater ability to handle personal crises and intention to make change had greater self-efficacy to change health behaviours. Development of stress management skills may improve self-efficacy, and proactive health education may foster knowledge before chronic disease develops.
