Association between results of an amyloid PET scan and healthcare utilization in individuals with cognitive impairment

BACKGROUND

The Imaging Dementia Evidence for Amyloid Scanning (IDEAS) study reports that amyloid PET scans help providers diagnose and manage Alzheimer's disease and related dementias (ADRD). Using CARE-IDEAS, an IDEAS supplemental study, we examined the association between amyloid PET scan result (elevated or non-elevated amyloid), patient characteristics, and participant healthcare utilization.

METHODS

We linked respondents in CARE-IDEAS study to their Medicare fee-for-service records (n = 1333). We examined participants' cognitive impairment-related, outpatient, emergency department (ED), and inpatient encounters in the year before compared with the 2 years after the amyloid PET scan.

RESULTS

Individuals with a non-elevated amyloid scan had more healthcare encounters throughout the overall study period than those with an elevated amyloid scan. Regardless of the amyloid scan result, cognitive impairment-related and outpatient encounters overall decreased, but ED and inpatient encounters increased in the 2 years after the scan compared with the year prior. There was minimal evidence of differences in healthcare utilization between participants with an elevated and non-elevated amyloid scan.

CONCLUSIONS

There is no difference in change in healthcare utilization between people with scans showing elevated and non-elevated beta-amyloid.

Social relations and contact with general practitioner in a middle-aged Danish population: a prospective register- and survey-based cohort study

Background

Findings about the relationship between individuals’ social relations and general practitioner (GP) contact are ambiguous as to whether weak social relations are associated with an increased or decreased consultation pattern. Furthermore, social relations may affect GP contact differently for men compared to women, between socioeconomic groups and according to perceived need. The overall aim of the study is to examine the association between functional aspects of social relations, perceived emotional and instrumental social support, the tendency to consult a GP and the frequency of GP contact.

Methods

The study comprised 6911 individuals aged 49–61 at baseline from the Copenhagen Aging and Midlife Biobank (CAMB). We conducted a two-part regression to explore the association between perceived emotional and instrumental social support and GP contact (tendency and frequency), controlling for age, sex, occupational social class, cohabitation status and number of morbidities.

Results

Results show no overall effect of the perceived social support aspects of social relations on GP contact independent of health-related needs.

Conclusions

Our results do not support that perceived social support, reflecting functional aspects of social relations, are associated with general practitioner contact among middle-aged people.

Trial registration

The study has been registered and approved by the Danish Data Protection Agency and the local ethical committee (approval No.H-A-2008-126 and No. 2013-41-1814).Keywords: social relations, perceived social support, healthcare utilisation, general practitioner, middle-aged

Conventional health care service utilization among cancer survivors that visit traditional and complementary providers in the Tromsø study: a cross-sectional study

Background

Traditional and complementary medicine (T&CM) is commonly used among cancer patients worldwide. Cancer patients in Norway mainly visit T&CM providers in addition to conventional health care services. It is not known how their utilization of T&CM providers influences their use of conventional health care services. The aim of this study was to investigate the difference between the utilization of conventional health care services among cancer survivors that visit T&CM providers and those that do not, and their associated factors.

Method

Health care service utilization data were obtained from cancer survivors 40 years and above participating in the Tromsø Study: Tromsø 7 conducted in 2015–2016. Data were collected from self-administered questionnaires. Pearson chi-square tests, Fisher exact tests, t-test, and logistic regression were used, with the significance level considered at p < 0.05.

Results

Of 1553 individuals, 10% (n = 155) reported visiting T&CM providers in the past 12 months. As both cancer survivors visiting and not visiting T&CM providers were frequent users of conventional health care, no significant differences were found in the overall use of conventional health care (98.1vs.94.5%, p = .056). Users of T&CM providers were however more likely to visit physiotherapists (40.1% vs 25%, p < .001), emergency rooms (29.2% vs 16.5%, p < .001), chiropractors (17% vs 6%, p < .001), and psychologist/psychiatrist (8.9% vs 3.4%, p < .001). They also had more frequent visits to conventional health care (11.45 vs 8.31 yearly visits, p = 0.014), particularly to general practitioners (5.21 visits vs. 3.94 visits, p = .002).

Conclusion

Results from this study show that visits to T&CM providers are associated with more visits to conventional health care services among cancer survivors. Further studies are needed to investigate the reasons for this high use behavior.

Use of health care services among Syrian refugees migrating to Norway: a prospective longitudinal study

Background

Understanding the differential utilization of healthcare services is essential to address the public health challenges. Through the migration process, refugees move from one set of health risk factors to another and can face multiple healthcare challenges along their journey. Yet how these changing risk factors influence refugees’ use of health care services is poorly understood.

Methods

A longitudinal survey assessing health care utilization of 353 adult Syrian refugees was conducted; first in a transit setting in Lebanon and after one year of resettlement in Norway. The main outcomes are the utilization of general practitioner services, emergency care, outpatient and/or specialist care and hospitalization during the previous 12 months. Associations between use of healthcare services and several sociodemographic, migration-related and health status variables at both time points were found using regression analysis. We also analyzed longitudinal changes in utilization rates using generalized estimating equations.

Results

The use of general practitioner and emergency care increased after resettlement while outpatient/specialist care markedly dropped, and hospitalization rates remained the same. Undocumented status and poor self-rated health (SRH) prior to resettlement were identified as predictors for use of health care after arrival. After resettlement, higher health literacy, higher education, higher social support and poor SRH and quality of life were significantly associated with use of healthcare services.

Conclusions

Utilization of health services changes post migration to the destination country and are associated with migration-related and socio-demographic factors. Poor SRH is associated with use of services, both pre-arrival and post-resettlement. Our findings have implications for future resettlements, health care policies and service provision to newly arrived refugees with regard to both health needs as well as delivery of services.

Characterization of occupational, demographic and health determinants in Canadian reservists veterans and the relationship with poor self-rated health

BACKGROUND

Self-rated health is an useful indicator of the general health in specific populations and used to propose interventions after service in the military context. However, there is scarce literature about self- rated health (SRH) in the Canadian Veterans of the Reserve Force and its relationship with demographic, health and occupational characteristics of this specific group. The aims of this research were to determine the SRH in Canadian Reserve Force Veterans and to explore the relationship between demographic, military service and health factors by reserve class.

METHODS

Data from the individuals was collected from the Life After Service (LASS) 2013 survey, including Veterans with Reserve Class C (n = 922) and Class A/B (n = 476). Bivariate and multivariate analysis using logistic regression models, were used to assess the association between the demographic characteristics, physical health, mental health, and military service characteristics and the self-rate health by both reserve classes.

RESULTS

The overall prevalence of poor SRH in Reserve Class C Veterans was 13.1% (CI:11.08-15.4) and for Reserve Class A/B was 6.9% (CI:5.0-9.1). Different degrees of associations were observed during the bivariate analysis and two different models were produced for each reserve class. Veterans of Reserve Class C showed that being single was (OR = 2.76, CI: 1.47-5.16), being 50-59 years old (OR = 4.6, CI: 1.28-17.11), reporting arthritis (OR = 2.49, CI: 1.33-4.67), back problems (OR = 3.02, CI:1.76-5.16), being obese (OR = 1.96, CI: 1.13-3.38), depression (OR = 2.34, CI: 1.28-4.20), anxiety (OR = 4.11, CI: 2.00-8.42), PTSD (OR = 2.1 CI: 0.98-4.47), PTSD (OR = 20.9, CI:0.98-4.47) and being medically released (OR = 4.48, CI: 2.43-8.24) were all associated with higher odds of poor SRH. The Reserve Class A/B model showed that completing high school (OR = 4.30, CI: 1.37-13.81), reporting arthritis (6.60, CI: 2.15-20.23), diabetes (OR = 11.19, CI: 2.72-46.0), being obese (OR = 3.37, CI: 1.37-8.27), daily smoking (OR = 2.98, CI: 1.05-8.38), having anxiety (OR = 9.8, CI: 3.70-25.75) were associated with higher odds of poor SRH.

CONCLUSIONS

These results suggested that the relationship of poor SRH with demographic, health and military occupation domains varied depending on the class on the Reserve Force Service. Different strengths of association showed different risk compositions for both populations. This can be used to better understand the health and well-being of Veterans of the Reserve Force.

Do the determinants of self-rated health vary among older people with disability, chronic diseases or both conditions in urban Colombia?

Our study aimed to identify the main determinants of self-rated health for individuals aged 60 years or older in Bogotá, Colombia, and if those determinants vary between groups. Data was obtained from the Demographic Health Survey 2011 for Bogotá. Logistic regression models were estimated to identify the determinants of excellent/good self-rated health among people aged 60 years or older living in Bogotá. Moreover, a subgroup analysis was conducted seeking to identify if the determinants changed between groups (men, women, persons with disability, with chronic disease(s), and persons with both disability and chronic disease(s)). The likelihood of reporting an excellent/good self-rated health health decreases when the individual has a disability, a chronic disease or reports that their household income is not enough to cover the basic needs. On the other hand, the odds of reporting excellent/good self-rated health increase when the individual is more educated and reports to receive family support. The subgroup analysis showed that although some determinants are only associated with one group (age with chronic diseases), in general, three main determinants stood out: years of education, socioeconomic status variables and receiving family support. The determinants of self-rated health for older adults in Bogotá differ according to the disability and the chronic disease status. Thus, public policies aiming to improve the levels of health and quality must consider the impacts of those characteristics on individuals' perceptions of their own health.

Trends in socioeconomic inequalities in self-rated health in Germany: a time-trend analysis of repeated cross-sectional health surveys between 2003 and 2012

OBJECTIVES

This study assessed the extent of educational and income inequalities in self-rated health (SRH) in the German adult population between 2003 and 2012 and how these inequalities changed over time.

DESIGN

Repeated cross-sectional health interview surveys conducted in 2003, 2009, 2010 and 2012.

SETTING AND PARTICIPANTS

The study population was the German adult population aged 25-69, living in private households in Germany. In total 54 197 randomly selected participants (2003: 6890; 2009: 16 418; 2010: 17 145; 2012: 13 744) were included.

MAIN OUTCOME MEASURES

SRH was assessed with one single question. Five answer categories were dichotomised into good ('very good' and 'good') versus poor ('moderate', 'poor', 'very poor') SRH. To estimate the extent of the correlation between absolute and relative inequalities in SRH on the one hand, and income and education on the other; slope indices of inequality (SII) and relative indices of inequality (RII) were estimated using linear probability and log-binomial regression models.

RESULTS

There were considerable and persisting educational and income inequalities in SRH in every survey year. Absolute educational inequalities were largely stable (2003: SII=0.25, 95% CI 0.21 to 0.30; 2012: 0.29, 95% CI 0.25 to 0.33; p trend=0.359). Similarly, absolute income inequalities were stable (2003: SII=0.22, 95% CI 0.17 to 0.27; 2012: SII=0.26, 95% CI 0.22 to 0.30; p trend=0.168). RII by education (2003: 2.53, 95% CI 2.11 to 3.03; 2012: 2.72, 95% CI 2.36 to 3.13; p trend=0.531) and income (2003: 2.09. 95% CI 1.75 to 2.49; 2012: 2.53, 95% CI 2.19 to 2.92; p trend=0.051) were equally stable over the same period.

CONCLUSIONS

We found considerable and persisting absolute and relative socioeconomic inequalities in SRH in the German adult population between 2003 and 2012, with those in lower socioeconomic position reporting poorer SRH. These findings should be a concern for both public health professionals and political decision makers.

Adequate health literacy is associated with better health outcomes in people with type 2 diabetes in Mexico

This study evaluates the health literacy of people with type 2 diabetes and its association with health outcomes. We conducted a cross-sectional survey in two family medicine clinics of the Mexican Institute of Social Security that included 778 diabetic patients >19 years of age. The Spanish version of the European Health Literacy questionnaire served to measure health literacy. Multiple logistic regressions were performed to determine the association between the independent variable (health literacy) and dependent variables (good self-rated health, glycemic control, and diabetes-related hospitalizations) after controlling for conceptually relevant patient's characteristics. Only 17.6% of patients had adequate health literacy; while, the remaining percentage showed inadequate (23%), or problematic (59.4%) health literacy. After adjusting for the patients' characteristics, those with adequate health literacy had 4.66 (95%CI: 2.26-9.61) times the odds of good self-rated health compared to those with inadequate literacy. Patients with adequate health literacy had 0.65 (95%CI: 0.49-0.86) times the odds of hospitalization due to diabetes compared to those with inadequate literacy. Compared to inadequate health literacy, problematic literacy was associated with increased odds of glycemic control. In conclusion, healthcare providers should actively address the health literacy needs of patients to increase good self-rated health, glucose control and reduce hospitalizations.

Patient-centered primary care and self-rated health in 6 Latin American and Caribbean countries: Analysis of a public opinion cross-sectional survey

BACKGROUND

Despite the substantial attention to primary care (PC), few studies have addressed the relationship between patients' experience with PC and their health status in low-and middle-income countries. This study aimed to (1) test the association between overall patient-centered PC experience (OPCE) and self-rated health (SRH) and (2) identify specific features of patient-centered PC associated with better SRH (i.e., excellent or very good SRH) in 6 Latin American and Caribbean countries.

METHODS AND FINDINGS

We conducted a secondary analysis of a 2013 public opinion cross-sectional survey on perceptions and experiences with healthcare systems in Brazil, Colombia, El Salvador, Jamaica, Mexico, and Panama; the data were nationally representative for urban populations. We analyzed 9 features of patient-centered PC. We calculated OPCE score as the arithmetic mean of the PC features. OPCE score ranged from 0 to 1, where 0 meant that the participant did not have any of the 9 patient-centered PC experiences, while 1 meant that he/she reported having all these experiences. After testing for interaction on the additive scale, we analyzed countries pooled for aim 1, with an interaction term for Mexico, and each country separately for aim 2. We used multiple Poisson regression models double-weighted by survey and inverse probability weights to deal with the survey design and missing data. The study included 6,100 participants. The percentage of participants with excellent or very good SRH ranged from 29.5% in Mexico to 52.4% in Jamaica. OPCE was associated with reporting excellent or very good SRH in all countries: adjusting for socio-demographic and health covariates, patients with an OPCE score of 1 in Brazil, Colombia, El Salvador, Jamaica, and Panama were more likely to report excellent or very good SRH than those with a score of 0 (adjusted prevalence ratio [aPR] 1.61, 95% CI 1.37-1.90, p < 0.001); in Mexico, this association was even stronger (aPR 4.27, 95% CI 2.34-7.81, p < 0.001). The specific features of patient-centered PC associated with better SRH differed by country. The perception that PC providers solve most health problems was associated with excellent or very good SRH in Colombia (aPR 1.38, 95% CI 1.01-1.91, p = 0.046) and Jamaica (aPR 1.21, 95% CI 1.02-1.43, p = 0.030). Having a provider who knows relevant medical history was positively associated with better SRH in Mexico (aPR 1.47, 95% CI 1.03-2.12, p = 0.036) but was negatively associated with better SRH in Brazil (aPR 0.71, 95% CI 0.56-0.89, p = 0.003). Finally, easy contact with PC facility (Mexico: aPR 1.35, 95% CI 1.04-1.74, p = 0.023), coordination of care (Mexico: aPR 1.53, 95% CI 1.19-1.98, p = 0.001), and opportunity to ask questions (Brazil: aPR 1.42, 95% CI 1.11-1.83, p = 0.006) were each associated with better SRH. The main study limitation consists in the analysis being of cross-sectional data, which does not allow making causal inferences or identifying the direction of the association between the variables.

CONCLUSIONS

Overall, a higher OPCE score was associated with better SRH in these 6 Latin American and Caribbean countries; associations between specific characteristics of patient-centered PC and SRH differed by country. The findings underscore the importance of high-quality, patient-centered PC as a path to improved population health.

Older Adults' Social Relationships and Health Care Utilization: A Systematic Review

BACKGROUND

Deficiencies in older people's social relationships (including loneliness, social isolation, and low social support) have been implicated as a cause of premature mortality and increased morbidity. Whether they affect service use is unclear.

OBJECTIVES

To determine whether social relationships are associated with older adults' use of health services, independently of health-related needs.

SEARCH METHODS

We searched 8 electronic databases (MEDLINE, Embase, CINAHL, Web of Science, PsycINFO, Scopus, the Cochrane Library, and the Centre for Reviews and Dissemination) for data published between 1983 and 2016. We also identified relevant sources from scanning the reference lists of included studies and review articles, contacting authors to identify additional studies, and searching the tables of contents of key journals.

SELECTION CRITERIA

Studies met inclusion criteria if more than 50% of participants were older than 60 years or mean age was older than 60 years; they included a measure of social networks, received social support, or perceived support; and they reported quantitative data on the association between social relationships and older adults' health service utilization.

DATA COLLECTION AND ANALYSIS

Two researchers independently screened studies for inclusion. They extracted data and appraised study quality by using standardized forms. In a narrative synthesis, we grouped the studies according to the outcome of interest (physician visits, hospital admissions, hospital readmissions, emergency department use, hospital length of stay, utilization of home- and community-based services, contact with general health services, and mental health service use) and the domain of social relationships covered (social networks, received social support, or perceived support). For each service type and social relationship domain, we assessed the strength of the evidence across studies according to the quantity and quality of studies and consistency of findings.

MAIN RESULTS

The literature search retrieved 26 077 citations, 126 of which met inclusion criteria. Data were reported across 226 678 participants from 19 countries. We identified strong evidence of an association between weaker social relationships and increased rates of readmission to hospital (75% of high-quality studies reported evidence of an association in the same direction). In evidence of moderate strength, according to 2 high-quality and 3 medium-quality studies, smaller social networks were associated with longer hospital stays. When we considered received and perceived social support separately, they were not linked to health care use. Overall, the evidence did not indicate that older patients with weaker social relationships place greater demands on ambulatory care (including physician visits and community- or home-based services) than warranted by their needs.

AUTHORS' CONCLUSIONS

Current evidence does not support the view that, independently of health status, older patients with lower levels of social support place greater demands on ambulatory care. Future research on social relationships would benefit from a consensus on clinically relevant concepts to measure. Public Health Implications. Our findings are important for public health because they challenge the notion that lonely older adults are a burden on all health and social care services. In high-income countries, interventions aimed at reducing social isolation and loneliness are promoted as a means of preventing inappropriate service use. Our review cautions against assuming that reductions in care utilization can be achieved by intervening to strengthen social relationships.
