Polypharmacy occurrence and the related risk of premature death among older adults in Denmark: A nationwide register-based cohort study

Background

Polypharmacy, defined as the concurrent use of ≥5 medications, increases the risk of drug-drug and drug-disease interactions as well as non-adherence to drug therapy. This may have negative health consequences particularly among older adults due to age-related pharmacokinetic and pharmacodynamic changes. This study aims to uncover the occurrence of polypharmacy among older adults in Denmark and investigate how polypharmacy relates to mortality.

Method

This nationwide register-based study included 1,338,058 adults aged 65+ years between January 2013 and December 2017 in Denmark. Polypharmacy prevalence was measured at time of inclusion while incidence and the association between polypharmacy and mortality were measured over the five-year follow-up using Cox regression. In an attempt to adjust for confounding by indication, propensity scores with overlap weighting were introduced to the regression model.

Results

At time of inclusion, polypharmacy prevalence was 29% and over the five years follow-up, 47% of the remaining adults transitioned into polypharmacy. Identified risk factors included multimorbidity (2+ morbidities: HR = 3.51; 95% CI = 3.48–3.53), age (95+ years: HR = 2.85; 95% CI = 2.74–2.96), socioeconomic factors (Highest income quartile: HR = 0.81; 95% CI = 0.80–0.81), region of birth region (Non-western migrants: HR = 0.77; 95% CI = 0.75–0.79), marital status (Divorced: HR = 1.10; 95% CI = 1.10–1.12) and year of inclusion (2017: HR = 1.19; 95% CI = 1.19–1.22). Further analyses showed that polypharmacy involves many different drug cocktails with medication for the cardiovascular system (95%), blood and blood-forming organs (69%), alimentary tract and metabolism (61%) and nervous system (54%) contributing the most. After adjustment for propensity scores with OW, both polypharmacy (HR = 3.48, CI95% = 3.41–3.54) and excessive polypharmacy (HR = 3.48, CI95% = 3.43–3.53) increased the risk of death substantially.

Conclusion

A considerable proportion of older adults in Denmark were exposed to polypharmacy dependent on health status, socio-economic status, and societal factors. The associated three- to four-fold mortality risk indicate a need for further exploration of the appropriateness of polypharmacy among older adults.

Differential effects of colorectal cancer screening across sociodemographic groups in Denmark: a register-based study

INTRODUCTION

Colorectal cancer (CRC) does not affect different sociodemographic groups uniformly. CRC screening programmes could seek to reduce this inequality; however, the screening programmes themselves might be subject to differential participation across sociodemographic groups. This study investigates the sociodemographic inequality at all steps in Denmark's nationwide CRC screening programme: screening participation, faecal immunochemical test (FIT) results, colonoscopy compliance, CRC diagnosis, and cancer stage.

MATERIAL AND METHODS

This cohort study includes all first-time invitees from the beginning of the Danish population-based CRC screening programme from 1 March 2014 to 31 December 2017.

RESULTS

Sixty-four percent of the invitees participated in the screening programme, and of those 7% were FIT-positive. After being invited to further diagnostic procedures, 90% responded to the invitation, and among those 5% were CRC-positive. Among those diagnosed with CRC, 9% were stage IV. Through multivariable analyses, we identified sociodemographic inequalities in all steps of the screening programme from returning a stool sample to being diagnosed with CRC. Specifically, we identified inequalities across sex, age, migration status, relationship status, the screening status of one's partner, education, income, and use of health services. Women were more likely to participate compared to men (RR = 1.13; 95% CI: 1.12-1.13), but had a lower risk of a positive FIT result (RR = 0.67; 95% CI: 0.66-0.68) and of a CRC diagnosis (RR = 0.88; 95% CI: 0.82-0.93) compared to men. The likelihood of participating as well as the risk of positive FIT results and CRC diagnosis increased with age.

CONCLUSION

All steps of the screening programme were subject to sociodemographic inequalities. Interventions are needed to target groups identified as having lower uptake as well as high-risk of being FIT- and/or CRC-positive. These groups include males, individuals aged 60+ years and individuals who do not visit their GP regularly.

Do we know the effects of colorectal cancer screening? A short communication on selective uptake and differential effects of colorectal cancer screening in Scandinavia

Colorectal cancer (CRC) contributes extensively to the overall cancer burden, with substantial and increasing social inequality in both incidence and survival. In several countries, this social inequality in incidence and survival has been increasing over time, and the increase is expected to continue. To overcome this, it is advised to implement nationwide CRC screening programmes, as these are effective in detecting possible signs of CRC, hence identifying earlier-stage cancer and reducing mortality. However, little is known about the distribution of these effects across population groups. It is possible that the outcomes of CRC screening are not equally distributed among participants, but rather that the screening programme serves some population groups better than others. The aim of this short communication based on published data is to describe the status of selective uptake according to sociodemographic and economic factors in CRC screening in Scandinavia. Furthermore, we raise questions that need to be addressed in future research in order to grasp the full effects of the screening programme and ultimately to ensure high uptake as well as participation in subsequent diagnostic procedures across population groups.

Improving Dietary Behavior Among Ethnic Minority Women in Denmark: A Feasibility Study Based on a Participatory and Culturally Adapted Intervention

The Danish Heart Foundation and the non-governmental organization Neighborhood Mothers have co-developed a culturally adapted intervention seeking to promote healthy dietary behaviour among ethnic minority women. This feasibility study explores the potential of the intervention to reach ethnic minority women using health promotion initiatives. Participants attended instructor courses or cooking events, where culturally adapted, healthy recipes were introduced and meals prepared. Feasibility was explored using a mixed-method approach. Surveys were completed by 59 volunteers and 150 participants at five instructor courses and 21 cooking events. Individual interviews and focus group discussions were conducted with volunteers and participants after completion of the intervention. After the intervention, 61% of the 150 participants had high levels of knowledge about dietary recommendations, 96% intended to cook healthy dishes in the future and 84% intended to incorporate measuring equipment into their daily cooking routine. Participants with a high level of knowledge reported intention to change dietary behaviour more often than participants with lower levels of knowledge. Interviews confirmed that the participants cooked healthy dishes after participating, and incorporated knowledge about healthy food practices into their daily cooking. Few participants used measuring equipment. The intervention proved to be feasible as a health promotion initiative targeting a hard-to-reach population.

The association between loneliness and health - a survey-based study among middle-aged and older adults in Denmark

BACKGROUND

While the association between overall poor health and loneliness among older adults continues to be examined closely, less attention has been given to middle-aged adults. This paper examines the relationship between loneliness and health as measured by self-rated health, physical ability and multi-morbidity in a large sample of Danish adults between the ages of 52-92 years. Furthermore, it identifies vulnerable groups with regard to the year of birth and gender.

METHOD

We apply the survey-study method, using data collected by The Danish National Centre for Social Research in 2012. We analysed the association between loneliness and health in 9154 Danish adults through multi-variate regression analyses adjusting for the year of birth, gender, marital status, cohabitation status, employment status and home ownership.

RESULTS

We found that loneliness was associated with increased risks of poor self-rated health (OR, 2.58; 95% Cl, 1.20-3.35), limited physical abilities (OR, 1.91; 95% Cl, 1.58-2.32) and multiple diagnoses (OR, 1.77; 95% Cl, 1.48-2.12). Lonely middle-aged adults (52-62 years of age) had an increased risk of having limited physical abilities.

CONCLUSION

Among middle-aged and older Danish adults, loneliness was strongly associated with poor self-rated health, limited physical ability and multi-morbidity.
