- Background: People with intermediate CVD risk constitute most of the population. Within this group, the proportion of events is lower compared to the high-risk group, but they contribute with the largest absolute number of events. Atherosclerosis is a dynamic process and progression can be slowed or even reversed with medication and lifestyle changes, but adherence to prescribed treatment is crucial.Aim: To investigate the long-term effects of interventions with pictorial risk communication of cardiovascular (CVD) risk on average adherence in a group of statin users. Compare response in adherence over time between men and women after intervention.Methods: Participants on active statin treatment were followed up to 5 years after being randomly assigned to an intervention program aimed at raising CVD risk awareness among participants and their physicians. Merging prescribed medication databases with VIPVIZA study to study adherence over time. A moving average adherence was used to compare groups.Results: Generally, the average adherence to statins among the 512 participants was high. Men had a higher average adherence over time, while women had a sharper increase in adherence in conjuncture with the intervention program.Conclusions: Both men and women were receptive to pictorial information regarding CVD risk, but the intervention effect was more pronounced in women. Sex differences are important when considering risk communication strategies. Periodically repeating the intervention was beneficial for maintaining the intervention effect over time.

- Background: The increased risk of adverse drug reactions due to age-related altered pharmacokinetics and pharmacodynamics is a challenge when prescribing medications to older people, and especially among older people with major neurocognitive disorder who are particularly sensitive to drug effects. The aim of this study was to investigate the use of potential inappropriate medications (PIMs) in 2012 and 2017 among old people with major neurocognitive disorder. A secondary aim was to investigate factors associated with PIM use.Methods: This register-study was based on the Swedish registry for cognitive/dementia disorders and the Swedish prescribed drug register. Criteria from the National Board of Health and Welfare were used to identify PIMs between 1 July–31 December 2012 and 1 July-–31 December 2017 among people ≥ 65 years. Drug use was defined as one or more filled prescriptions during each timeframe.Results: The total use of PIMs declined significantly between 2012 (28.7%) and 2017 (21.7%). All PIMs and PIM groups declined between these years, except for antipsychotic drugs, which increased from 11.6% to 12.3%. The results from the multiple regression model found that PIM use was associated with younger age (OR: 0.97 CI: 0.96–0.97), a lower Mini Mental State Examination score (OR: 0.99 CI: 0.99–1.00), the use of multi-dispensed drugs (OR: 2.05 CI: 1.93–2.18), and compared to Alzheimer’s disease, with the subtypes dementia with Lewy bodies and Parkinson’s disease dementia (OR: 1.57 CI: 1.40–1.75), frontotemporal dementia (OR: 1.29 CI: 1.08–1.54) and vascular dementia (OR: 1.10 CI: 1.03–1.16).Conclusions: Overall, the use of PIMs decreased between the years 2012 and 2017. The increase of antipsychotic drugs and the association between PIM use and multi-dispensed drugs warrant concern.

- Purpose As people get older, their sensitivity to drugs and adverse drug reactions can increase due to pharmacokinetic and pharmacodynamic changes. Older people with dementia are a particularly vulnerable group of people. They are at an increased risk of being prescribed potentially inappropriate medications, which may lead to harmful consequences. The aim of this study was to investigate the prevalence of potentially inappropriate medications among older patients with cognitive impairment. Methods Medical records for patients aged ≥65 years admitted to two hospitals in Northern Sweden were reviewed. Potentially inappropriate medications were identified using the EU(7)-PIM list as an identification tool. Results Of 428 patients included in the study, 40.9% had one or more potentially inappropriate medication prescribed. The most commonly represented potentially inappropriate medication classes were hypnotics and sedatives, cardiovascular drugs and laxatives. The most commonly involved potentially inappropriate medications were zopiclone, digoxin and sodium picosulfate. There was an association seen between having a higher number of medications prescribed and having one or more potentially inappropriate medication. Conclusion Potentially inappropriate medications are prevalent among older people with cognitive impairment living in Northern Sweden. It is important to continuously evaluate the need for potentially inappropriate medications in this patient group, in order to prevent adverse drug reactions, especially among those who have a higher number of medications prescribed.

- Purpose: Increased numbers of drugs and changes in pharmacokinetic and pharmacodynamic parameters among elderly people contribute to increased prevalence of adverse drug reactions. Drug-drug interactions (DDIs) are an important reason for admission to hospital and elderly people with dementia are particularly vulnerable. The aims of the present study were to assess the occurrence and characteristics of clinically relevant DDIs and to investigate potential risk factors associated with DDIs among elderly people with dementia.Methods: People 65 years with dementia, admitted to two hospitals in Northern Sweden, were included. The medical records of 458 patients were reviewed. Clinically relevant DDIs were identified using the Janusmed interactions database. Pharmacological classification was conducted using Stockley's classification system.Results: A total of 401 DDIs were identified among 43.2% of the study population, of which 98.5% had interactions that may require dose adjustment and 7.6% had drug combinations that should be avoided. Pharmacodynamic interactions were most common, of which furosemide-citalopram (n=35) were most frequently observed. Omeprazol-citalopram (n=25) was the most common drug combination among pharmacokinetic interactions. Citalopram and warfarin were the most commonly involved drug substances. An association was found between a higher number of medications being prescribed and having at least one DDI.Conclusion: Clinically relevant drug-drug interactions are prevalent among elderly people with dementia living in Northern Sweden. Drug-drug interactions should be identified in order to manage and prevent adverse outcomes. This is particularly important among this group of people especially when multiple medications are being prescribed.

Tidskriftsartikel (refereegranskat)abstract
- Background Older people are more sensitive to drugs and adverse drug reactions than younger people because of age-related physiological changes such as impaired renal function. As people with dementia are particularly vulnerable to the effects of drugs, it is especially important to evaluate the dosages of renally cleared medications in this group. Objective The aim of this study was to estimate the prevalence of impaired renal function and inappropriate prescriptions on the basis of renal function among older patients with dementia or cognitive impairment. Methods The medical records of 428 patients aged ≥65 years who were admitted to two hospitals in northern Sweden were reviewed and renally cleared medications were identified. The Cockcroft–Gault equation was used to evaluate renal function. Doses were evaluated according to the Geriatric Dosage Handbook.Results Renal function was impaired (estimated glomerular filtration rate <60 ml/min) in 65.4 % of the study population. Impaired renal function was associated with increasing age. Among 547 prescriptions identified as renally cleared medications, 9.1 % were inappropriate based on the patient’s renal function; 13.5 % of the 326 patients prescribed renally cleared medications had inappropriate prescriptions. Inappropriate prescriptions were more common among patients living in nursing homes.Conclusions Impaired renal function is common and inappropriate prescription is prevalent among old people with cognitive impairment in northern Sweden. Continuous consideration of renal function is important when prescribing medications to this group.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: The aging process contributes to alterations in organ systems, which lead to an increased risk for chronic conditions. Drug treatment is an important strategy in the management of chronic conditions; however, pharmacokinetic and pharmacodynamic alterations contribute to increased sensitivity to drug effects. This sensitivity is even more pronounced among older people with major neurocognitive disorder. Nevertheless, this group of people is often exposed to potentially inappropriate drug treatment associated with serious adverse drug reactions.Aim: To identify patterns of potentially inappropriate drug treatment and factors associated with this type of drug treatment among older people with cognitive impairment to enable further improvement of drug treatment and diminish the risk of adverse drug reactions among this vulnerable group of people.Method: Explicit criteria were utilized to identify inappropriate prescriptions based on renal function, potentially inappropriate medications according to age and clinically relevant drug-drug interactions among older people with cognitive impairment admitted to two hospitals in Northern Sweden. The first two studies included 428 people and the third study 458 people. Medical records were used as the data source. Moreover, explicit criteria were used to identify potentially inappropriate medications according to age among 1,881 and 1,305 nursing home residents in Västerbotten county in 2007 and 2013, respectively. The association between the length of nursing home stay and the use of potentially inappropriate medications were investigated based on information in questionnaires. Finally, the use of potentially inappropriate medications according to age were investigated three years pre- and post-diagnosis of major neurocognitive disorder among 67,226 older people registered in the Swedish registry for cognitive/dementia disorders.Results: Every tenth of the people admitted to hospital had at least one inappropriate prescription based on their estimated renal function. Moreover, 40.9% had at least one potentially inappropriate medication and 43.2% had at least one clinically relevant drug-drug interaction. Pharmacodynamic interactions were found to be the most common type. Increasing number of prescribed medications was significantly associated with having at least one potentially inappropriate medication according tovage and at least one clinically relevant drug-drug interaction, respectively. Moreover, potentially inappropriate medications were common among nursing home residents but had decreased 2013 compared to 2007 and were only to a lesser extent associated with the length of stay. In the nationwide study population, it was found that potentially inappropriate medications according to age were overall low and decreased continuously three years pre-diagnosis until three years post-diagnosis of major neurocognitive disorder. Consequently, the use of potentially inappropriate medications was found to be significantly lower post- diagnosis except when concerning antipsychotic drug treatment, which was significantly higher post-diagnosis when compared with the pre- diagnosis period.Conclusion: Potentially inappropriate drug treatment is common among older people with cognitive impairment admitted to the hospitals in Västerbotten regardless of their type of living. Increasing number of medications was significantly associated with potentially inappropriate medications and clinically relevant drug-drug interactions. The decreasing trend of potentially inappropriate medications among nursing home residents and among older people with a major neurocognitive disorder is positive and indicates an increased awareness of potentially inappropriate drug treatment in healthcare.

- Background: The use of potentially inappropriate medications (PIMs) is a problem since it might contribute significantly to adverse drug reactions and hospital admissions among elderly with major neurocognitive disorder (NCD). To assess the appropriateness of drug treatment, different explicit criteria have been developed.Objectives: To investigate and compare the prevalence of PIM users among elderly with major NCD on a nationwide basis using 3 different explicit criteria. Furthermore, the study aimed to investigate factors associated with the use of PIMs.Methods: This nationwide register-based study included 35,212 people, 65 years or older, diagnosed with major NCD and registered in the Swedish registry for cognitive/dementia disorders up to June 30, 2017 and alive December 31, 2017. PIMs were identified using 3 different explicit criteria; the Swedish quality indicators, the EU(7)-PIM list and the AGS Beers Criteria. PIM use was defined as having collected a minimum of one PIM at least once between July 01 – December 31, 2017.Results: The numbers of people using one or more PIMs were 7629 (21.7%) according to the Swedish quality indicators, 11,838 (33.6%) according to the EU(7)-PIM list, and 12,002 (34.1%) according to AGS Beers Criteria. Antipsychotics, antithrombotic agents and anxiolytics were the most frequently used PIM class according to the different assessment tools, respectively. The use of PIMs was positively associated with vascular dementia and Lewy body dementia/Parkinson's disease dementia, regardless of the assessment tool used. However, the association between using at least one PIM and age, sex, MMT-value and frontotemporal dementia, differed depending on the criteria used.Conclusions: The different results and included PIMs indicate the different perspectives on PIMs between criteria, which make it difficult to compare the results. However, psychotropic drug use requires further highlighting, as well as the association between PIM use and different types of major NCD.

Tidskriftsartikel (refereegranskat)abstract
- Background: To investigate the use of potentially inappropriate medications and their relation to the length of nursing home stay among older adults.Methods: Questionnaire surveys using the Multi-Dimensional Dementia Assessment scale were sent out to all nursing homes in Västerbotten county in northern Sweden in 2007 and 2013. In total, 3186 adults (1881 from 2007 and 1305 from 2013) ≥65 years old were included and 71.8% of those had cognitive impairment. Potentially inappropriate medications were identified using drug-specific quality indicators according to Swedish National Board of Health and Welfare.Results: Potentially inappropriate medications were used by 48.0% of the 2007 study sample and by 28.4% of the 2013 study sample. The prevalence of glibenclamide use 2007 and antipsychotic drug use 2013 increased linearly (β = 0.534E− 3, 95% CI: 0.040E− 3-0.103E− 2, p = 0.034 and β = 0.155E− 2, 95% CI: 0.229E− 3-0.288E− 2, p = 0.022, respectively) with the length of nursing home stay. No significant association was found between the prevalence of propiomazine, codeine, long-acting benzodiazepines, anticholinergics, NSAIDs, tramadol or the total use of potentially inappropriate medications and the length of stay in nursing homes in 2007 or 2013. Antipsychotics were the most commonly prescribed of the drug classes investigated and used by 22.6% of the residents 2007 and by 16.0% of the residents 2013.Conclusions: These results indicate that treatment with potentially inappropriate medications is common among older adults living in nursing homes, but it seems to be related to the length of nursing home stay only to a smaller extent. Drug treatment should regularly be reviewed and followed-up among nursing home residents regardless of their length of nursing home stay, in order to prevent unnecessary adverse events.

Tidskriftsartikel (refereegranskat)abstract
- Objective: The aim of the present study was to investigate how potentially inappropriate medication usage and anti-dementia drug use change from 3 years prior to, up until 3 years post-diagnosis of major neurocognitive disorders among older people living in Sweden. Methods: People registered in the Swedish registry for cognitive/dementia disorders from 1 July, 2008 to 31 December, 2017, and aged 68 years or older at diagnosis, were included (n = 67,226). Data were combined with the Swedish Prescribed Drug Registry to obtain information about drugs collected in 6-month periods at Swedish pharmacies from 3 years pre-diagnosis until 3 years post-diagnosis. Potentially inappropriate medications were identified according to Swedish national guidelines. A generalised estimating equation regression model and estimated marginal means were used. Results: Of the 67,226 people included in the study population, 59.2% were women and the mean age ± standard deviation was 81.5 ± 6.4 years, 47.0% lived together with a spouse or partner, and 88.9% were living at home at the time of diagnosis. The proportions of people using potentially inappropriate medications continuously decreased pre- and post-diagnosis, except for antipsychotic drug use, which continuously increased both pre- and post-diagnosis. Moreover, anticholinergic drug use increased pre-diagnosis and declined post-diagnosis. When comparing the periods pre- and post-diagnosis date, the adjusted proportion of people using potentially inappropriate medications was significantly lower post-diagnosis compared with pre-diagnosis, except for the adjusted proportion using antipsychotics, which was significantly higher post-diagnosis, 10.6%, compared with the period before, 3.1% (adjusted odds ratio 3.71; 95% confidence interval 3.59–3.83). The adjusted proportion of people using anticholinergic drugs was significantly lower post-diagnosis, 7.2%, compared with the pre-diagnosis period, 8.9% (adjusted odds ratio 0.80; 95% confidence interval 0.78–0.82). Anti-dementia drug use was significantly higher post-diagnosis, 52.6%, when compared with the pre-diagnosis period, 3.5% (adjusted odds ratio 30.13; 95% confidence interval 29.19–31.10). Conclusions: Overall, the prevalence of people using potentially inappropriate medications decreased and was significantly lower post-diagnosis of major neurocognitive disorders, except for antipsychotics. This indicates that potentially inappropriate medication use should be noticed and reviewed among all older people. The small decrease in the prevalence of anticholinergic drug users and the increasing proportions of people using antipsychotic drugs post-diagnosis are of special concern because of the adverse drug reactions associated with these types of potentially inappropriate medications. Consequently, it is important to identify and regularly question anticholinergic and antipsychotic drug treatment to prevent unnecessary and serious adverse drug reactions among a vulnerable group of people.
