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.

Educational differences in long-term care use in Sweden during the last two years of life.

Background: In old age, many people experience a period of functional decline and require long-term care. Sweden has a universal largely tax-financed health and social care system that is used by all societal groups. However, few studies have investigated if educational groups use publicly paid long-term care equitably. The aim of this study was to explore educational differences in the use of long-term care, including both home care and institutional care, during the last two years of life in Sweden. Methods: We used linked register data on mortality and long-term care use, including all adults aged ⩾67 years who died in Sweden in November 2015 (N=6329). We used zero-inflated negative binomial regression models to analyse the number of months with long-term care by educational level, both crude and adjusted for age at death and cohabitation status. Men and women were analysed separately. Results: People with tertiary education died more commonly without using any long-term care compared to primary educated people (28.0% vs. 18.6%; p<0.001). In the adjusted model, educational differences in the estimated number of months with long-term care disappeared among men but remained significant among women (primary educated: odds ratio=17.3 (confidence interval 16.8-17.7); tertiary educated: odds ratio=15.8 (confidence interval 14.8-16.8)). Conclusions: Older adults spend considerable time in their last two years of life with long-term care. Only minor educational differences in long-term care use remained after adjustment for cohabitation status and age at death. This suggest that Sweden's publicly financed long-term system achieves relatively equitable use of long-term care at the end of life.

Increasing inequalities in disability-free life expectancy among older adults in Sweden 2002-2014.

BACKGROUND: In an aging society with increasing old age life expectancy, it has become increasingly important to monitor the health development in the population. This paper combines information on mortality and disability and explores educational inequalities in disability-free life expectancy in the aging population in Sweden, and to what extent these inequalities have increased or decreased over time. METHODS: A random sample of the Swedish population aged 77 years and above (n=2895) provided information about disability in the population in the years 2002, 2004, 2011 and 2014. The prevalence of disability was assessed by five items of personal activities of daily living and incorporated in period life tables for the corresponding years, using the Sullivan method. The analyses were stratified by sex and educational attainment. Estimates at ages 77 and 85 years are presented. RESULTS: Disability-free life expectancy at age 77 years increased more than total life expectancy for all except men with lower education. Women with higher education had a 2.7-year increase and women with lower education a 1.6-year increase. The corresponding numbers for men were 2.0 and 0.8 years. The educational gap in disability-free life expectancy increased by 1.2 years at age 77 years for both men and women. CONCLUSIONS: While most of the increase in life expectancy was years free from disability, men with lower education had an increase of years with disability. The educational differences prevailed and increased over the period as the gains in disability-free life expectancy were smaller among those with lower education.

History of working conditions and the risk of old-age dependency: a nationwide Swedish register-based study.

AIMS: There is substantial evidence that previous working conditions influence post-retirement health, yet little is known about previous working conditions' association with old-age dependency. We examined job strain, hazardous and physical demands across working life, in relation to the risk of entering old-age dependency of care. METHODS: Individually linked nationwide Swedish registers were used to identify people aged 70+ who were not receiving long-term care (residential care or homecare) at baseline (January 2014). Register information on job titles between the years 1970 and 2010 was linked with a job exposure matrix of working conditions. Random effects growth curve models were used to calculate intra-individual trajectories of working conditions. Cox regression models with age as the timescale (adjusted for living situation, educational attainment, country of birth, and sex) were conducted to estimate hazard ratios for entering old-age dependency during the 24 months of follow-up (n = 931,819). RESULTS: Having initial adverse working conditions followed by an accumulation throughout working life encompassed the highest risk of entering old-age dependency across the categories (job strain: HR 1.23, 95% CI 1.19-1.27; physical demands: HR 1.36, 95% CI 1.31-1.40, and hazardous work: HR 1.35, 95% CI 1.30-1.40). Initially high physical demands or hazardous work followed by a stable trajectory, or initially low-level physical demand or hazardous work followed by an accumulation throughout working life also encompassed a higher risk of dependency. CONCLUSIONS: A history of adverse working conditions increased the risk of old-age dependency. Reducing the accumulation of adverse working conditions across the working life may contribute to postponing old-age dependency.

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.

Life-course trajectories of working conditions and successful ageing.

AIMS: As populations are ageing worldwide, it is important to identify strategies to promote successful ageing. We investigate how working conditions throughout working life are associated with successful ageing in later life. METHODS: Data from two nationally representative longitudinal Swedish surveys were linked (n=674). In 1991, respondents were asked about their first occupation, occupations at ages 25, 30, 35, 40, 45 and 50 years and their last recorded occupation. Occupations were matched with job exposure matrices to measure working conditions at each of these time points. Random effects growth curve models were used to calculate intra-individual trajectories of working conditions. Successful ageing, operationalised using an index including social and leisure activity, cognitive and physical function and the absence of diseases, was measured at follow-up in 2014 (age 70 years and older). Multivariable ordered logistic regressions were used to assess the association between trajectories of working conditions and successful ageing. RESULTS: Intellectually stimulating work; that is, substantive complexity, in the beginning of one's career followed by an accumulation of more intellectually stimulating work throughout working life was associated with higher levels of successful ageing. In contrast, a history of stressful, hazardous or physically demanding work was associated with lower levels of successful ageing. CONCLUSIONS: Promoting a healthy workplace, by supporting intellectually stimulating work and reducing physically demanding and stressful jobs, may contribute to successful ageing after retirement. In particular, it appears that interventions early in one's employment career could have positive, long-term effects.

Trends over two decades in life expectancy with complex health problems among older Swedes: implications for the provision of integrated health care and social care.

BACKGROUND: Due to population aging, it is essential to examine to what extent rises in life expectancy (LE) consist of healthy or unhealthy years. Most health expectancy studies have been based on single health measures and have shown divergent trends. We used a multi-domain indicator, complex health problems (CHP), indicative of the need for integrated medical and social care, to investigate how LE with and without CHP developed in Sweden between 1992 and 2011. We also addressed whether individuals with CHP more commonly lived in the community in 2011 compared to earlier years. METHODS: CHP were defined as having severe problems in at least two of three health domains related to the need for medical and/or social care: symptoms/diseases, cognition/communication, and mobility. The Swedish Panel Study of Living Conditions of the Oldest Old (SWEOLD), a nationally representative survey of the Swedish population aged ≥ 77 years with waves in 1992, 2002 and 2011 (n≈2000), was used to estimate the prevalence of CHP. Age- and gender-specific death rates were obtained from the Human Mortality Database. The Sullivan method was deployed to calculate the remaining life expectancy with and without CHP. The estimates were decomposed to calculate the contribution of changes from morbidity and mortality to the overall trends in LE without CHP. RESULTS: Between 1992 and 2011, both total LE (+ 1.69 years [95% CI 1.56;1.83] and LE without CHP (+ 0.84 years [-0,87;2.55]) at age 77 increased for men, whereas LE at age 77 increased for women (+ 1.33 [1.21;1.47]) but not LE without CHP (-0.06 years [-1.39;1.26]). When decomposing the trend, we found that the increase in LE with CHP was mainly driven by an increase in the prevalence of CHP. Among individuals with CHP the proportion residing in care homes was lower in 2011 (37%) compared to 2002 (58%) and 1992 (53%). CONCLUSIONS: The findings, that an increasing number of older people are expected to live more years with CHP, and increasingly live in the community, point towards a challenge for individuals and families, as well as for society in financing and organizing coordinated and coherent medical and social services.

Growing Income-Based Inequalities in Old-Age Life Expectancy in Sweden, 2006-2015.

Sweden is known for high life expectancy and economic egalitarianism, yet in recent decades it has lost ground in both respects. This study tracked income inequality in old-age life expectancy and life span variation in Sweden between 2006 and 2015, and examined whether patterns varied across levels of neighborhood deprivation. Income inequality in remaining life expectancy at ages 65, 75, and 85 increased. The gap in life expectancy at age 65 grew by more than a year between the lowest and the highest income quartiles, for both men (from 3.4 years in 2006 to 4.5 years in 2015) and women (from 2.3 to 3.4 years). This widening income gap in old-age life expectancy was driven by different rates of mortality improvement: individuals with higher incomes increased their life expectancy at a faster rate than did those with lower incomes. Women with the lowest incomes experienced no improvement in old-age life expectancy. Furthermore, life span variation increased in the lowest income quartile, while it decreased slightly among those in the highest quartile. Income was found to be a stronger determinant of old-age life expectancy than neighborhood deprivation.

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.

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.

Drug use among complete responders, partial responders and non-responders in a longitudinal survey of nonagenarians: analysis of prescription register data.

PURPOSE: In observational studies, non-response can limit representativity and introduce bias. We aimed to investigate the longitudinal changes in the number of used drugs among complete responders, partial responders, and non-responders in a whole birth cohort of Danish nonagenarians participating in a longitudinal survey. METHODS: We obtained prescription data on all individuals born in 1905 and living in Denmark when the Danish 1905 cohort study was initiated in 1998 (n = 3600) using the Danish National Prescription Registry. Drug use was assessed for complete responders, non-responders at baseline, and partial responders (i.e., dropouts) in the 4-month period preceding each wave of the study (1998, 2000, 2003, and 2005), that is, as the cohort aged from 92-93 to 99-100 years. RESULTS: Complete responders, non-responders, and partial responders used a similar number of drugs at baseline, on average 4.4, increasing to 5.6 at the age of 99-100 years. In all groups, the number of used drugs increased over time; partial responders had the largest increase of 0.39 drugs per year (95% confidence interval (CI): 0.33-0.44) compared with 0.32 (95%CI: 0.27-0.37) and 0.30 (95%CI: 0.25-0.35) in the other groups. Furthermore, the most frequently used drug classes (e.g., loop diuretics and paracetamol) and the drug classes with the largest change (e.g., increase: laxatives and paracetamol; decrease: benzodiazepines) were similar across response groups. CONCLUSIONS: The number of used drugs increased in all response groups between the age of 92 and 100 years. In this study, drug use among complete responders was representative of the general drug use in the entire cohort. Copyright © 2016 John Wiley & Sons, Ltd.

Inequalities in health care use among older adults in Sweden 1992-2011: a repeated cross-sectional study of Swedes aged 77 years and older.

AIMS: In the last decades, the Swedish health care system was reformed to promote free choice; however, it has been questioned whether older adults benefit from these reforms. It has also been proposed that reforms promoting free choice might increase inequalities in health care use. Thus, the aim of this study is to investigate socioeconomic differences in health care use among older adults in Sweden, from 1992 to 2011. METHODS: The Swedish Panel Study of the Living Conditions of the Oldest Old (SWEOLD) is a nationally representative study of Swedes over 76 years old, including both institutionalized and community-dwelling persons. We analyzed cross-sectional data from SWEOLD waves in 1992, 2002 and 2011 (n ≈ 600/wave); and performed multivariate analyses to investigate whether socioeconomic position was associated with health care use (inpatient, outpatient and dental services) after need was accounted for. RESULTS: For the period of 1992-2011, we found that higher education was associated with more use of outpatient and dental care, both before and after adjustment for need. The association between education and inpatient or outpatient care use did not change over time. There was an increase in the proportion of older adults whom used dental care over the 19-year period, and there was a tendency for the socioeconomic differences regarding dentist visits to decrease over time. CONCLUSIONS: Our study covering 19 years showed relatively stable findings for socioeconomic differences in health care use among older adults in Sweden. We found there was a slight decrease in inequality in dental care; but unchanged socioeconomic differences in outpatient care, regardless of the changes that occurred in the Swedish health care system.

Socioeconomic inequalities in access to specialized psychotropic prescribing among older Swedes: a register-based study.

BACKGROUND: Mental disorders among older adults are mainly treated with psychotropic drugs. Few of these drugs are, however, prescribed by specialized geriatricians or psychiatrists, but rather from general practitioners (GPs). Socioeconomic inequalities in access to specialist prescribing have been found in younger age groups. Hence, we aimed to investigate whether there are socioeconomic differences in access to geriatrician and psychiatrist prescribing of psychotropic drugs among older adults. METHODS: By record-linkage of The Swedish Prescribed Drug Register and The Swedish Education Register, we obtained information for persons aged 75-89 years who had filled a prescription for psychotropic drugs (antipsychotics, anxiolytics, hypnotic/sedatives or antidepressants) with information on prescriber specialty from July to October 2005 (n = 221 579). Multinomial regression analysis was used to investigate whether education was associated with geriatrician and psychiatrist prescribing of psychotropic drugs. RESULTS: The vast majority of the psychotropic drugs were prescribed by 'GPs and other specialists' (∼95% GPs). Older adults with higher educational level were more likely to be prescribed psychotropic drugs from psychiatrists and geriatricians. However, after adjustment for place of residence, the association between patient's education and prescription by a geriatrician disappeared, whereas the association with seeing a psychiatrist was only attenuated. CONCLUSION: Access to specialized prescribing of psychotropics is unequally distributed between socioeconomic groups of older adults in Sweden. This finding was partially confounded by place of residence for geriatrician but not for psychiatrist prescribing. Further research should examine if inequalities in specialized psychotropic prescribing translate into worse outcomes for socioeconomically deprived and non-metropolitan-living older individuals.

Trends in Drug Duplications in Swedish Older Adults: A Nationwide Register Study from 2006 to 2021.

BACKGROUND: Drug duplication (DD), the use of two identical drugs simultaneously, is a medication error increasing the risk of adverse drug events. We describe the trends and implicated drugs in potential DD in older adults in Sweden from 2006 to 2021. METHODS: We conducted a register-based, repeated cross-sectional study of all older adults (aged ≥65 years) dispensed drugs at a community pharmacy in 2006-2021. DD was defined as a ≥30-day overlap of two dispensations of drugs with the same 5th level (chemical substance) Anatomical Therapeutic Chemical (ATC) classification, but with different brand names, within a 3-month period each year. RESULTS: Among Swedish older adults with ordinary prescriptions (i.e. multidose excluded; n ≈ 1,200,000-1,600,000 per year), the prevalence of potential DD increased from 5.2% to 10.6% in 65- to 79-year-olds and from 7.0% to 11.7% in those aged ≥80 years. The drug groups (ATC level 3; pharmacological subgroup) most frequently implicated in DD in 2006 were ß-blocking agents, angiotensin-converting enzyme (ACE) inhibitors, and calcium channel blockers, and in 2021 Vitamin B12 and folic acid, ß-blocking agents and angiotensin II receptor blockers. CONCLUSIONS: DD represents a common but unnecessary and potentially hazardous medication error. Our results indicate that during the last two decades, the prevalence has almost doubled in older adults with ordinary prescriptions, reaching 11% in 2021. More national efforts are needed to revert this trend, including a nationally available complete drug list for all patients, and prescriber support to detect DD.

Spousal bereavement and four-year trajectories of medication use: A nationwide register-based study in Swedish older adults.

BACKGROUND: Medication use around widowhood has been poorly described for most medication classes. Medication use patterns can reflect health consequences of spousal loss, as previously shown for psychotropic drugs. METHODS: We used data from nationwide health registers (2008-2020) to describe the patterns of use of dispensed medications in all widowed Swedes aged ≥65 years followed between 2 years before and 2 years after spousal death. All prescription drugs used by at least 5% of the cohort were considered according to their therapeutic subgroups (Anatomical Therapeutic Chemical [ATC] classification system 2nd level). We used group-based trajectory models to cluster widowed individuals into up to 4 distinct longitudinal patterns of monthly medication use. We ranked the therapeutic subgroups with similar patterns according to their plausibility to reflect potential health effects of spousal loss, compared to those of psycholeptics (mainly anxiolytics, hypnotics) and psychoanaleptics (mainly antidepressants) as the references. RESULTS: From 212,111 widowed adults included (68% female and 70% aged ≥75 years), we observed a significant increasing trend in medication use, especially after spousal death, for 21 out of the 39 different therapeutic subgroups that were used by at least 5% (most represented pharmacological groups: cardiovascular system, nervous system, and alimentary tract and metabolism). This increasing trend often concerned only a small proportion of individuals, with varying magnitude and speed of change in medication use across therapeutic subgroups. The patterns of use of antiepileptics, laxatives, skin emollients/protectives, analgesics, and drugs for anemia, constipation, or peptic ulcers, were the closest to those of references, displaying the largest changes in use, and were therefore ranked as the most likely to reflect health effects of spousal loss. CONCLUSION: Our results confirmed the increase in psychotropic medications' use in widowed older adults and identified several potential physical health effects of spousal loss that warrant further research.

Cholinesterase inhibitors and non-steroidal anti-inflammatory drugs and the risk of peptic ulcers: A self-controlled study.

BACKGROUND: Non-steroidal anti-inflammatory drugs (NSAIDs) should be used with caution in adults aged 65 years and older. Their gastrointestinal adverse event risk might be further reinforced when using concomitant cholinesterase inhibitors (ChEIs). We aimed to investigate the association between NSAIDs and ChEI use and the risk of peptic ulcers in adults aged 65 years and older. METHODS: Register-based self-controlled case series study including adults ≥65 years with a new prescription of ChEIs and NSAIDs, diagnosed with incident peptic ulcer in Sweden, 2007-2020. We identified persons from the Total Population Register individually linked to several nationwide registers. We estimated the incidence rate ratio (IRR) of peptic ulcer with a conditional Poisson regression model for four mutually exclusive risk periods: use of ChEIs, NSAIDs, and the combination of ChEIs and NSAIDs, compared with the non-treatment in the same individual. Risk periods were identified based on the prescribed daily dose, extracted via a text-parsing algorithm, and a 30-day grace period. RESULTS: Of 70,060 individuals initiating both ChEIs and NSAIDs, we identified 1500 persons with peptic ulcer (median age at peptic ulcer 80 years), of whom 58% were females. Compared with the non-treatment periods, the risk of peptic ulcer substantially increased for the combination of ChEIs and NSAIDs (IRR: 9.0, [6.8-11.8]), more than for NSAIDs alone (5.2, [4.4-6.0]). No increased risks were found for the use of ChEIs alone (1.0, [0.9-1.2]). DISCUSSION: We found that the risk of peptic ulcer associated with the concomitant use of NSAIDs and ChEIs was over and beyond the risk associated with NSAIDs alone. Our results underscore the importance of carefully considering the risk of peptic ulcers when co-prescribing NSAIDs and ChEIs to adults aged 65 years and older.

Comparison of sociodemographic factors, healthcare utilisation by general practitioner visits, somatic hospital admissions, and medication use in Norway, Sweden, and Denmark.

PURPOSE: The healthcare systems in Scandinavia inform nationwide registers and the Scandinavian populations are increasingly combined in research. We aimed to compare Norway (NO), Sweden (SE), and Denmark (DK) regarding sociodemographic factors and healthcare. METHODS: In this cross-sectional study, we analyzed aggregated data from the nationwide Scandinavian registers. We calculated country-specific statistics on sociodemographic factors and healthcare use (general practitioner visits, admissions to somatic hospitals, and use of medicines). RESULTS: In 2018, population were 5295,619 (NO), 10,120,242 (SE), and 5781,190 (DK). The populations were comparable regarding sex, age, education, and income distribution. Overall, medication use was comparable, while there was more variation in hospital admissions and general practitioner visits. For example, per 1000 inhabitants, 703 (NO), 665 (SE), and 711 (DK) individuals redeemed a prescription, whereas there were 215 (NO), 134 (SE), and 228 (DK) somatic hospital admissions per 1000 inhabitants. General practitioner contacts per 1000 inhabitants were 7082 in DK and 5773 in NO (-data from SE). CONCLUSION: The Scandinavian countries are comparable regarding aggregate-level sociodemographic factors and medication use. Variations are noted in healthcare utilisation as measured by visits to general practitioners and admissions to hospitals. This variation should be considered when comparing data from the Scandinavian countries.

Applicability of STOPP/START prescribing criteria in integrated Swedish administrative health registries and a Swedish population-based cohort.

PURPOSE: The STOPP/START criteria are frequently applied in observational studies to assess potentially inappropriate prescribing in older adults. This study aimed to assess the applicability of the three available STOPP/START versions in two distinct data sources. METHODS: To evaluate the applicability of the three versions of STOPP/START criteria, we used two observational data sources: (i) Integrated Swedish administrative health registries (ISHR) encompassing routinely collected health data and (ii) the population-based Swedish National study on Aging and Care in Kungsholmen (SNAC-K), based on health professional-led clinical assessments. The Anatomical Therapeutic Classification code (ATC) was used to categorise medications. Diseases were categorised using the international classification of diseases version 10 (ICD10). RESULTS: The first STOPP/START version demonstrated an applicability rate of 80% in ISHR and 84% in SNAC-K. The second version demonstrated an applicability of 64% in ISHR and 74% in SNAC-K. The third version showed an applicability of 66% in ISHR and 77% in SNAC-K. Challenges in applicability included broad definitions, vague terminology, and the lack of information on disease severity, symptomatic traits, and stability of certain conditions. CONCLUSION: The applicability of the STOPP/START criteria in observational studies seems to have decreased in more recent versions of the tool. Population-based studies with comprehensive clinical assessments may offer higher applicability compared to studies based on administrative data. Future versions of the STOPP/START criteria should prioritise clear and unambiguous definitions to improve their applicability in research and promote result generalisability and comparability.
