Long-term care use, hospitalizations and mortality during COVID-19 in Finland and Sweden: A nationwide register-based study in 2020.

AIM: To describe long-term care (LTC) use in Finland and Sweden in 2020, by reporting residential entry and exit patterns including hospital admissions and mortality, compared with the 2018-2019 period and community-living individuals. METHODS: From national registers in Finland and Sweden, all individuals 70+ were included. Using the Finnish and Swedish study populations in January 2018 as the standard population, we reported changes in sex- and age-standardized monthly rates of entry into and exit from LTC facilities, mortality and hospital admission among LTC residents and community-living individuals in 2020. RESULTS: Around 850,000 Finns and 1.4 million Swedes 70+ were included. LTC use decreased in both countries from 2018 to 2020. In the first wave (March/April 2020), Finland experienced a decrease in LTC entry rates and an increase in LTC exit rates, both more marked than Sweden. This was largely due to short-term movements. Mortality rates peaked in April and December 2020 for LTC residents in Finland, while mortality peaked for both community-living individuals and LTC residents in Sweden. A decrease in hospital admissions from LTC facilities occurred in April 2020 and was less marked in Finland versus Sweden. CONCLUSIONS: During the first wave of the pandemic mortality was consistently higher in Sweden. We also found a larger decrease in LTC use and, among LTC residents, a smaller decrease in hospital admissions in Finland than in Sweden. This study calls for assessing the health consequences of the differences observed between these two Scandinavian countries as part of the lessons from the COVID-19 pandemic.

Longitudinal effects of using and discontinuing central nervous system medications on cognitive functioning.

PURPOSE: To investigate the longitudinal effect of using and discontinuing central nervous system (CNS) medications on cognitive performance. METHODS: Using longitudinal cognitive data from population representative adults aged 25-100 years (N = 2188) from four test waves 5 years apart, we investigated both the link between use of CNS medications (opioids, anxiolytics, hypnotics and sedatives) on cognitive task performance (episodic memory, semantic memory, visuospatial ability) across 15 years, and the effect of discontinuing these medications in linear mixed effects models. RESULTS: We found that opioid use was associated with decline in visuospatial ability whereas using anxiolytics, hypnotics and sedatives was not associated with cognitive decline over 15 years. A link between drug discontinuation and cognitive improvement was seen for opioids as well as for anxiolytics, hypnotics and sedatives. CONCLUSIONS: Although our results may be confounded by subjacent conditions, they suggest that long-term use of CNS medications may have domain-specific negative effects on cognitive performance over time, whereas the discontinuation of these medications may partly reverse these effects. These results open up for future studies that address subjacent conditions on cognition to develop a more complete understanding of the cognitive effects of CNS medications.

Determinants of suicidal behavior in dementia: A Swedish national register-based study.

OBJECTIVES: To examine predictors of suicidal behavior (SB) in adults aged 75 years and above with dementia. DESIGN: Longitudinal national register-based study. PARTICIPANTS AND SETTING: Swedish residents aged ≥75 years with dementia identified in the Swedish Dementia Registry (SveDem) between 1 January 2007 and 31 December 2017 (N = 59 042) and followed until 31 December 2018. Data were linked with numerous national registers using personal identity numbers. MEASUREMENTS: Outcomes were nonfatal self-harm and suicide. Fine and Gray regression models were used to investigate demographics, comorbidities, and psychoactive medications associated with fatal and nonfatal SB. RESULTS: Suicidal behavior was observed in 160 persons after dementia diagnosis; 29 of these died by suicide. Adjusted sub-hazard ratio (aSHRs) for SB was increased in those who had a previous episode of self-harm (aSHR = 14.42; 95% confidence interval [CI] = 7.06-29.46), those with serious depression (aSHR = 4.33, 95%CI = 2.94-6.4), and in those born outside Sweden (aSHR = 1.53; 95% CI = 1.03-2.27). Use of hypnotics or anxiolytics was also associated with a higher risk of SB; use of antidepressants was not. Milder dementia and higher frailty score also increased risk of SB. Risk was decreased in those who received home care (aSHR = 0.52; 95%CI = 0.38-0.71) and in the oldest group (aSHR = 0.35; 95%CI = 0.25-0.49). CONCLUSION: In addition to established targets for suicidal behavior prevention (improved identification and treatment of depression and previous self-harm), several new risk factors were suggested. There is a need for innovative public health strategies to meet the needs of older dementia patients with a foreign background. Home care may have a potential positive effect to prevent SB in people with dementia, but this needs to be further explored.

Lipid-lowering treatment intensity, persistence, adherence and goal attainment in patients with coronary heart disease.

BACKGROUND: To examine patterns of lipid-lowering therapy (LLT) use, and persistence and adherence among patients with coronary heart disease and their associations with lipoprotein cholesterol (LDL-C) goal attainment. METHODS: Observational study among 26,768 patients who had suffered a myocardial infarction or had been revascularized in Stockholm during 2012 to 2018, and followed up through 2019. Outcomes included initiation of LLT, discontinuation, re-initiation, adherence to treatment and LDL-C goal attainment according to the European dyslipidaemia guidelines from 2011 and 2016 (mainly LDL-C <1.8 mmol/L). RESULTS: 82% of patients commenced or continued LLT within 90 days after discharge. Of those, 71% were dispensed an LLT prescription within 30 days (62% of them for high-intensity LLT). High-intensity LLT prescribing increased over time, from 12% in 2012 to 78% in 2018. During a median follow-up of 3 (IQR 2-5) years 73% continued to fill prescriptions for a statin, 26.3% temporarily or permanently discontinued, and 0.5% changed to non-statin LLT. Only 1.3% discontinued statin treatment permanently. Throughout observation, about 80% of patients showed good statin adherence (proportion of days covered ≥80%). LDL-C target attainment was 52% the first year and <50% during subsequent years. LDL-C goal attainment was highest among patients receiving high-intensity statin treatment and showing good treatment adherence. CONCLUSION: In secondary prevention for patients with established coronary heart disease, the proportion of LDL-C target attainment was low throughout the time period of the study, despite increasing use of high-intensity LLT and good treatment persistence and adherence.

Potential overtreatment in end-of-life care in adults 65 years or older dying from cancer: applying quality indicators on nationwide registries.

BACKGROUND: Quality indicators are frequently used to measure the quality of care at the end of life. Whether quality indicators of potential overtreatment (i.e., when the risks outweigh the benefits) at the end of life can be reliably applied to routinely collected data remains uncertain. This study aimed to identify quality indicators of overtreatment at the end of life in the published literature and to investigate their tentative prevalence among older adults dying with solid cancer. MATERIALS AND METHODS: Retrospective cohort study of decedents including all older adults (≥65 years) who died with solid cancer between 1 January 2013 and 31 December 2015 (n = 54,177) in Sweden. Individual data from the National Cause of Death Register were linked with data from the Total Population Register, the National Patient Register, and the Swedish Prescribed Drug Register. Quality indicators were applied for the last one and three months of life. RESULTS: From a total of 145 quality indicators of overtreatment identified in the literature, 82 (57%) were potentially operationalisable with routine administrative and healthcare data in Sweden. Unidentifiable procedures and hospital drug treatments were the reason for non-operationalisability in 52% of the excluded indicators. Among the 82 operationalisable indicators, 67 measured overlapping concepts. Based on the remaining 15 unique indicators, we tentatively estimated that overall, about one-third of decedents received at least one treatment or procedure indicative of 'potential overtreatment' during their last month of life. CONCLUSION: Almost half of the published overtreatment indicators could not be measured in routine administrative and healthcare data in Sweden due to a lack of means to capture the care procedure. Our tentative estimates suggest that potential overtreatment might affect one-third of cancer decedents near death. However, quality indicators of potential overtreatment for specific use in routinely collected data should be developed and validated.

Sexual and gender harassment and use of psychotropic medication among Swedish workers: a prospective cohort study.

OBJECTIVE: To estimate the prospective association between the exposure to three types of gender-based violence and harassment (GBVH) and psychotropic medication. METHODS: Information on three measures of workplace GBVH-sexual harassment (1) from superiors or colleagues, (2) from others (eg, clients) and (3) gender harassment from superiors or colleagues-were retrieved from the biannual Swedish Work Environment Survey 2007-2013 (N=23 449), a representative sample of working 16-64 years old registered in Sweden. The survey answers were merged with data on antidepressants, hypnotics/sedatives and anxiolytics from the Swedish Prescribed Drug Register. Cox proportional hazards analyses with days to purchase as time scale and first instance of medicine purchase as failure event were fitted, adjusted for demographic and workplace factors. RESULTS: Workers who reported exposure to gender harassment only (HR 1.2, 95% CI 1.07 to 1.36), to sexual but not gender harassment (HR 1.21, 95% CI 1.04 to 1.40), or to gender and sexual harassment (HR 1.31, 95% CI 1.08 to 1.60) had an excess risk of psychotropics use in comparison to workers who reported neither of the exposures in the past 12 months. We found no interaction between the exposures and gender in the association with psychotropics use. CONCLUSIONS: Exposure to sexual or gender harassment at the workplace may contribute to the development of mental disorders.

Kidney function and prescribed dose in middle-aged and older patients starting selective serotonin reuptake inhibitors.

PURPOSE: To avoid adverse drug reactions, dose reductions are recommended when prescribing selective serotonin reuptake inhibitors (SSRIs) to patients with impaired kidney function. The extent of this practice in routine clinical care is however unknown. We aimed to evaluate the starting and maintenance SSRI doses prescribed to patients stratified by levels of kidney function in real-world practice. METHODS: Using data from the Stockholm CREAtinine Measurements (SCREAM) project, we identified 101 409 new users of antidepressants (including 52 286 SSRI users) in the region of Stockholm during 2006-2019, who were ≥50 years of age and had a recent creatinine test taken in order to estimate glomerular filtration rate (eGFR). SSRI dose reduction was defined as a prescribed SSRI dose of ≤0.5 defined daily doses, according to current recommendations. We examined the associations between eGFR and reductions in initial dose and maintenance dose of SSRIs using logistic regression models. RESULTS: Overall, reductions in initial and maintenance dose were observed among 54.1% and 34.1% of new SSRI users. Nevertheless, about 40% of individuals with an eGFR <30 ml/min/1.73 m2 were prescribed an SSRI without dose reduction. After adjusting for age and other covariates, lower eGFR was associated with moderately higher odds of dose reduction, for both initial and maintenance dose. Compared to individuals with an eGFR of 90-104 ml/min/1.73 m2 , the adjusted odds ratios for those with an eGFR <30 ml/min/1.73 m2 were 1.18 (95% CI: 1.03, 1.36) for initial dose reduction, and 1.49 (1.29, 1.72) for maintenance dose reduction. Stratified analyses showed stronger associations between lower eGFR and SSRI dose reduction among individuals aged 50-64 years and in those receiving prescriptions from psychiatric care. CONCLUSIONS: Lower kidney function was moderately associated with a reduced SSRI dose, independently of age. Prescribing SSRIs to middle-aged and older patients should not only consider patients' age but also their kidney function.

Validating a model for medication-related dental outcomes in older people.

OBJECTIVES: To externally validate a model for medication-related dental outcomes in (a) a general older population with dementia and (b) a matched population without dementia. SUBJECTS AND METHODS: This validation study used population-based data from seven Swedish national registers (2008-2017). Individuals aged 60+ with dementia were matched to those without dementia on age, gender, and county of residence at the date of diagnosis (index date). The exposure was continuous use of xerogenic medications during the 3-year period before index date. The primary outcome was the number of tooth extraction and restorative procedures within 3 years after index date. RESULTS: A total of 334,220 individuals were included in the final sample. In the dementia cohort, the use of urological drugs (incidence rate ratio [IRR] 1.08, 95% CI 1.03-1.13), respiratory medicines (IRR 1.10, 95% CI 1.04-1.17), and proton-pump inhibitors (IRR 1.09, 95% CI 1.05-1.13) was associated with the primary outcome. In the non-dementia cohort, respiratory medicines (IRR 1.03, CI 1.00-1.05), proton-pump inhibitors (IRR 1.06, CI 1.04-1.08), opioids (IRR 1.05, CI 1.03-1.07), and antidepressants (IRR 1.06, CI 1.04-1.08) were associated with the primary outcome. CONCLUSIONS: Although there were differences in prescription patterns, the model performed similarly in both those with and without dementia.

Attention-deficit/hyperactivity disorder and Alzheimer's disease and any dementia: A multi-generation cohort study in Sweden.

INTRODUCTION: We examined the extent to which attention-deficit/hyperactivity disorder (ADHD), a neurodevelopmental disorder, is linked with Alzheimer's disease (AD) and any dementia, neurodegenerative diseases, across generations. METHODS: A nationwide cohort born between 1980 and 2001 (index persons) were linked to their biological relatives (parents, grandparents, uncles/aunts) using Swedish national registers. We used Cox models to examine the cross-generation associations. RESULTS: Among relatives of 2,132,929 index persons, 3042 parents, 171,732 grandparents, and 1369 uncles/aunts had a diagnosis of AD. Parents of individuals with ADHD had an increased risk of AD (hazard ratio 1.55, 95% confidence interval 1.26-1.89). The associations attenuated but remained elevated in grandparents and uncles/aunts. The association for early-onset AD was stronger than late-onset AD. Similar results were observed for any dementia. DISCUSSION: ADHD is associated with AD and any dementia across generations. The associations attenuated with decreasing genetic relatedness, suggesting shared familial risk between ADHD and AD.

Cerebral Small Vessel Disease Associated With Atrial Fibrillation Among Older Adults: A Population-Based Study.

Background and Purpose: Cerebral small vessel disease, as a potential mechanism underlying the association between atrial fibrillation (AF) and dementia, remains poorly investigated. In this cohort study, we sought to examine the association between AF and cerebral small vessel disease markers among older adults. Methods: Data on 336 participants (age ≥60 years, mean 70.2 years; 60.2% women) free of dementia, disability, and cerebral infarcts were derived from the population-based Swedish National Study on Aging and Care in Kungsholmen. Structural brain magnetic resonance imaging examinations were performed at baseline (2001­2004) and follow-ups (2004­2007 and 2007­2010). Magnetic resonance imaging markers of cerebral small vessel disease included perivascular spaces, lacunes, and volumes of white matter hyperintensities, lateral ventricles, and total brain tissue. AF was assessed at baseline and follow-ups through clinical examinations, electrocardiogram, and medical records. Data were analyzed using linear mixed-effects models. Results: At baseline, 18 persons (5.4%) were identified to have prevalent AF and 17 (5.6%) developed incident AF over the 6-year follow-up. After multivariable adjustment, AF was significantly associated with a faster annual increase in white matter hyperintensities volume (ß coefficient=0.45 [95% CI, 0.04­0.86]) and lateral ventricular volume (0.58 [0.13­1.02]). There was no significant association of AF with annual changes in perivascular spaces number (ß coefficient=0.53 [95% CI, −0.27 to 1.34]) or lacune number (−0.01 [−0.07 to 0.05]). Conclusions: Independent of cerebral infarcts, AF is associated with accelerated progression of white matter lesions and ventricular enlargement among older adults.

Does Prolonged Education Causally Affect Dementia Risk When Adult Socioeconomic Status Is Not Altered? A Swedish Natural Experiment in 1.3 Million Individuals.

Intervening on modifiable risk factors to prevent dementia is of key importance, since progress-modifying treatments are not currently available. Education is inversely associated with dementia risk, but causality and mechanistic pathways remain unclear. We aimed to examine the causality of this relationship in Sweden using, as a natural experiment, data on a compulsory schooling reform that extended primary education by 1 year for 70% of the population between 1936 and 1949. The reform introduced substantial exogenous variation in education that was unrelated to pupils' characteristics. We followed 18 birth cohorts (n = 1,341,842) from 1985 to 2016 (up to ages 79-96 years) for a dementia diagnosis in the National Inpatient and Cause of Death registers and fitted Cox survival models with stratified baseline hazards at the school-district level, chronological age as the time scale, and cohort indicators. Analyses indicated very small or negligible causal effects of education on dementia risk (main hazard ratio = 1.01, 95% confidence interval: 0.98, 1.04). Multiple sensitivity checks considering only compliers, the pre-/post- design, differences in health-care-seeking behavior, and the impact of exposure misclassification left the results essentially unaltered. The reform had limited effects on further adult socioeconomic outcomes, such as income. Our findings suggest that without mediation through adult socioeconomic position, education cannot be uncritically considered a modifiable risk factor for dementia.

Individual changes in anthropometric measures after age 60 years: a 15-year longitudinal population-based study.

BACKGROUND: weight loss is commonly observed with ageing. We explored the trajectory of body mass index (BMI) and two proxies of muscle mass-calf circumference (CC) and mid-arm circumference (MAC)-and identified their determinants. METHODS: within the SNAC-K cohort, 2,155 dementia-free participants aged ≥60 years were followed over 15 years. BMI, CC and MAC were measured at baseline and follow-ups. Baseline sociodemographic and lifestyle factors were collected through interviews. Diabetes and vascular disorders were diagnosed by physicians through clinical examination and medical records. Data were analysed using linear mixed-effect models stratified by age (younger-old [<78 years] vs. older-old [≥78 years]). RESULTS: over the 15-year follow-up, BMI remained stable among participants aged 60 years at baseline (ßslope = 0.009 [95% confidence interval -0.006 to 0.024], P = 0.234) and declined significantly among those aged ≥66 years, while CC and MAC declined significantly across all age groups. The decline over 15 years in BMI, CC and MAC separately was 0.435 kg/m2, 1.110 cm and 1.455 cm in the younger-old and was 3.480 kg/m2, 3.405 cm and 3.390 cm in the older-old. In younger-old adults, higher education was associated with slower declines in all three measures, while vascular disorders and diabetes were associated with faster declines. In older-old adults, vigorous physical activity slowed declines in BMI and CC, while vascular disorders accelerated declines in BMI and MAC. CONCLUSIONS: CC and MAC declined earlier and more steeply than BMI. Cardiometabolic disorders accelerated such declines, while higher education and physical activity could counteract those declines.

Are there socio-economic inequalities in utilization of predictive biomarker tests and biological and precision therapies for cancer? A systematic review and meta-analysis.

BACKGROUND: Novel biological and precision therapies and their associated predictive biomarker tests offer opportunities for increased tumor response, reduced adverse effects, and improved survival. This systematic review determined if there are socio-economic inequalities in utilization of predictive biomarker tests and/or biological and precision cancer therapies. METHODS: MEDLINE, Embase, Scopus, CINAHL, Web of Science, PubMed, and PsycINFO were searched for peer-reviewed studies, published in English between January 1998 and December 2019. Observational studies reporting utilization data for predictive biomarker tests and/or cancer biological and precision therapies by a measure of socio-economic status (SES) were eligible. Data was extracted from eligible studies. A modified ISPOR checklist for retrospective database studies was used to assess study quality. Meta-analyses were undertaken using a random-effects model, with sub-group analyses by cancer site and drug class. Unadjusted odds ratios (ORs) and 95% confidence intervals (CIs) were computed for each study. Pooled utilization ORs for low versus high socio-economic groups were calculated for test and therapy receipt. RESULTS: Among 10,722 citations screened, 62 papers (58 studies; 8 test utilization studies, 37 therapy utilization studies, 3 studies on testing and therapy, 10 studies without denominator populations or which only reported mean socio-economic status) met the inclusion criteria. Studies reported on 7 cancers, 5 predictive biomarkers tests, and 11 biological and precision therapies. Thirty-eight studies (including 1,036,125 patients) were eligible for inclusion in meta-analyses. Low socio-economic status was associated with modestly lower predictive biomarker test utilization (OR 0.86, 95% CI 0.71-1.05; 10 studies) and significantly lower biological and precision therapy utilization (OR 0.83, 95% CI 0.75-0.91; 30 studies). Associations with therapy utilization were stronger in lung cancer (OR 0.71, 95% CI 0.51-1.00; 6 studies), than breast cancer (OR 0.93, 95% CI 0.78-1.10; 8 studies). The mean study quality score was 6.9/10. CONCLUSIONS: These novel results indicate that there are socio-economic inequalities in predictive biomarker tests and biological and precision therapy utilization. This requires further investigation to prevent differences in outcomes due to inequalities in treatment with biological and precision therapies.

Do Acetylcholinesterase Inhibitors Prevent or Delay Psychotropic Prescribing in People With Dementia? Analyses of the Swedish Dementia Registry.

OBJECTIVES: To investigate whether acetylcholinesterase inhibitor (AChEI) use prevents or delays subsequent initiation of psychotropic medications in people with Alzheimer's disease (AD) and Lewy body dementia (LBD). METHODS: Cohort study of 17,763 people with AD and LBD, without prior psychotropic use at time of dementia diagnosis, registered in the Swedish Dementia Registry from 2007 to 2015. Propensity score-matched regression models were used to compute hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between time-dependent AChEI use and risk of psychotropic initiation. RESULTS: Compared with matched comparators, AChEI users had a lower risk of antipsychotic (HR: 0.85, 95%CI: 0.75-0.95) and anxiolytic (HR: 0.76, 95%CI: 0.72-0.80) initiation. In subanalyses, this association remained significant at higher AChEI doses, and in AD but not LBD. There were no associations between AChEI use and initiation of antidepressants or hypnotics. CONCLUSION: AChEI use may be associated with lower risk of antipsychotic and anxiolytic initiation in AD, particularly at higher doses. Further investigation into aceytylcholinesterase inhibitors in behavioral and psychological symptoms of dementia management in LBD is warranted.

Factors of importance for discontinuation of thiazides associated with hyponatremia in Sweden: A population-based register study.

PURPOSE: In a patient with clinically significant hyponatremia without other clear causes, thiazide treatment should be replaced with another drug. Data describing to which extent this is being done are scarce. The aim of this study was to investigate sociodemographic and socioeconomic factors that may be of importance for the withdrawal of thiazide diuretics in patients hospitalized due to hyponatremia. METHODS: The study population was sampled from a case-control study investigating individuals hospitalized with a main diagnosis of hyponatremia. For every case, four matched controls were included. In the present study, cases (n = 5204) and controls (n = 7425) that had been dispensed a thiazide diuretic prior to index date were identified and followed onward regarding further dispensations. To investigate the influence of socioeconomic and sociodemographic factors, multiple logistic regression was used. RESULTS: The crude prevalence of thiazide withdrawal for cases and controls was 71.9% and 10.8%, respectively. Thiazide diuretics were more often withdrawn in medium-sized towns (adjusted OR, 1.52; 95% CI, 1.21-1.90) and rural areas (aOR, 1.81; 95% CI, 1.40-2.34) compared with metropolitan areas and less so among divorced (aOR, 0.72; 95% CI, 0.53-0.97). However, education, employment status, income, age, country of birth, and gender did not influence withdrawal of thiazides among patients with hyponatremia. CONCLUSIONS: Thiazide diuretics were discontinued in almost three out of four patients hospitalized due to hyponatremia. Educational, income, gender, and most other sociodemographic and socioeconomic factors were not associated with withdrawal of thiazides.

Extent and quality of drug use in community-dwelling people aged ≥75 years: A Swedish nationwide register-based study.

Aims: It is important for district nurses and other health professionals in primary care to gain more insight into the patterns and quality of drug use in community-dwelling older people, particularly in 75-year-olds, who have been the target of preventive home visits. This study aimed to examine the extent and quality of drug use in community-dwelling older people and to compare drug use in 75-year-olds with that of older age groups. Methods: Data from 2013 on people aged ≥75 years were obtained from the Swedish Prescribed Drug Register. Those living in the community (671,940/739,734 people aged ≥75 years) were included in the study. Quality of drug use was assessed by using a selection of indicators issued by the Swedish National Board of Health and Welfare. Results: The prevalence of polypharmacy and of many drug groups increased with age, as did several indicators of inappropriate drug use. However some drug groups, as well as inappropriate drugs, were prevalent in 75-year-olds and declined with age, for example diabetes drugs, drugs with major anticholinergic effects and nonsteroidal anti-inflammatory drugs. Conclusions: The substantial use of some drugs as early as 75 years of age confirms the value of including drug use as a topic in preventive home visits to 75-year-olds. The finding that polypharmacy and many measures of inappropriate drug use increased with age in community-dwelling older people also underscores the importance of district nurses' role in continuing to promote safe medication management at higher ages.

Preventive drugs in the last year of life of older adults with cancer: Is there room for deprescribing?

BACKGROUND: The continuation of preventive drugs among older patients with advanced cancer has come under scrutiny because these drugs are unlikely to achieve their clinical benefit during the patients' remaining lifespan. METHODS: A nationwide cohort study of older adults (those aged ≥65 years) with solid tumors who died between 2007 and 2013 was performed in Sweden, using routinely collected data with record linkage. The authors calculated the monthly use and cost of preventive drugs throughout the last year before the patients' death. RESULTS: Among 151,201 older persons who died with cancer (mean age, 81.3 years [standard deviation, 8.1 years]), the average number of drugs increased from 6.9 to 10.1 over the course of the last year before death. Preventive drugs frequently were continued until the final month of life, including antihypertensives, platelet aggregation inhibitors, anticoagulants, statins, and oral antidiabetics. Median drug costs amounted to $1482 (interquartile range [IQR], $700-$2896]) per person, including $213 (IQR, $77-$490) for preventive therapies. Compared with older adults who died with lung cancer (median drug cost, $205; IQR, $61-$523), costs for preventive drugs were higher among older adults who died with pancreatic cancer (adjusted median difference, $13; 95% confidence interval, $5-$22) or gynecological cancers (adjusted median difference, $27; 95% confidence interval, $18-$36). There was no decrease noted with regard to the cost of preventive drugs throughout the last year of life. CONCLUSIONS: Preventive drugs commonly are prescribed during the last year of life among older adults with cancer, and often are continued until the final weeks before death. Adequate deprescribing strategies are warranted to reduce the burden of drugs with limited clinical benefit near the end of life.

How many older adults receive drugs of questionable clinical benefit near the end of life? A cohort study.

BACKGROUND: The high burden of disease-oriented drugs among older adults with limited life expectancy raises important questions about the potential futility of care. AIM: To describe the use of drugs of questionable clinical benefit during the last 3 months of life of older adults who died from life-limiting conditions. DESIGN: Longitudinal, retrospective cohort study of decedents. Death certificate data were linked to administrative and healthcare registries with national coverage in Sweden. SETTING: Older adults (≥75 years) who died from conditions potentially amenable to palliative care between 1 January and 31 December 2015 in Sweden. We identified drugs of questionable clinical benefit from a set of consensus-based criteria. RESULTS: A total of 58,415 decedents were included (mean age, 87.0 years). During their last 3 months of life, they received on average 8.9 different drugs. Overall, 32.0% of older adults continued and 14.0% initiated at least one drug of questionable clinical benefit (e.g. statins, calcium supplements, vitamin D, bisphosphonates, antidementia drugs). These proportions were highest among younger individuals (i.e. aged 75-84 years), among people who died from organ failure and among those with a large number of coexisting chronic conditions. Excluding people who died from acute and potentially unpredictable fatal events had little influence on the results. CONCLUSION: A substantial share of older persons with life-limiting diseases receive drugs of questionable clinical benefit during their last months of life. Adequate training, guidance and resources are needed to rationalize and deprescribe drug treatments for older adults near the end of life.

Adequate, questionable, and inadequate drug prescribing for older adults at the end of life: a European expert consensus.

BACKGROUND: Clinical guidance is needed to initiate, continue, and discontinue drug treatments near the end of life. AIM: To identify drugs and drug classes most often adequate, questionable, or inadequate for older people at the end of life. DESIGN: Delphi consensus survey. SETTING/PARTICIPANTS: Forty European experts in geriatrics, clinical pharmacology, and palliative medicine from 10 different countries. Panelists were asked to characterize drug classes as "often adequate," "questionable," or "often inadequate" for use in older adults aged 75 years or older with an estimated life expectancy of ≤ 3 months. We distinguished the continuation of a drug class that was previously prescribed from the initiation of a new drug. Consensus was considered achieved for a given drug or drug class if the level of agreement was ≥ 75%. RESULTS: The expert panel reached consensus on a set of 14 drug classes deemed as "often adequate," 28 drug classes deemed "questionable," and 10 drug classes deemed "often inadequate" for continuation during the last 3 months of life. Regarding the initiation of new drug treatments, the panel reached consensus on a set of 10 drug classes deemed "often adequate," 23 drug classes deemed "questionable," and 23 drug classes deemed "often inadequate". Consensus remained unachieved for some very commonly prescribed drug treatments (e.g., proton-pump inhibitors, furosemide, haloperidol, olanzapine, zopiclone, and selective serotonin reuptake inhibitors). CONCLUSION: In the absence of high-quality evidence from randomized clinical trials, these consensus-based criteria provide guidance to rationalize drug prescribing for older adults near the end of life.

Is the level of education associated with transitions between care settings in older adults near the end of life? A nationwide, retrospective cohort study.

BACKGROUND: End-of-life transitions between care settings can be burdensome for older adults and their relatives. AIM: To analyze the association between the level of education of older adults and their likelihood to experience care transitions during the final months before death. DESIGN: Nationwide, retrospective cohort study using register data. SETTING/PARTICIPANTS: Older adults (⩾65 years) who died in Sweden in 2013 ( n = 75,722). Place of death was the primary outcome. Institutionalization and multiple hospital admissions during the final months of life were defined as secondary outcomes. The decedents' level of education (primary, secondary, or tertiary education) was considered as the main exposure. Multivariable analyses were stratified by living arrangement and adjusted for sex, age at time of death, illness trajectory, and number of chronic diseases. RESULTS: Among community-dwellers, older adults with tertiary education were more likely to die in hospitals than those with primary education (55.6% vs 49.9%; odds ratio (OR) = 1.21, 95% confidence interval (CI) = 1.14-1.28), but less likely to be institutionalized during the final month before death (OR = 0.83, 95% CI = 0.76-0.91). Decedents with higher education had greater odds of remaining hospitalized continuously during their final 2 weeks of life (OR = 1.12, 95% CI = 1.02-1.22). Among older adults living in nursing homes, we found no association between the decedents' level of education and their likelihood to be hospitalized or to die in hospitals. CONCLUSION: Compared with those who completed only primary education, individuals with higher educational attainment were more likely to live at home until the end of life, but also more likely to be hospitalized and die in hospitals.
