- 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.Trial registration: The VIPVIZA study is registered with ClinicalTrials.gov, May 8, 2013, number NCT01849575.

Tidskriftsartikel (refereegranskat)abstract
- Background and Purpose: Intravenous thrombolysis is a well-established treatment for acute ischemic stroke. Our aim was to quantify the effect of each minute delay in door-to-needle time (DNT) on 90-day survival, intracerebral hemorrhagic complication <36 hours, and functional outcomes at 3 months, in routine clinical practice.Methods: Our nationwide registry-based study included 14 132 adult patient admissions with ischemic stroke receiving intravenous thrombolysis from 2010 to 2017. Outcomes were analyzed using multivariable logistic regression, adjusting for potential confounders.Results: Median DNT was 47 minutes, with an improvement from 65 to 38 minutes during the study. Median age was 74 years, and median National Institutes of Health Stroke Scale 8 points. We found a significant impact of each minute delay in DNT with reduced odds of survival by 0.6%, increased odds of intracerebral hemorrhagic and worse activities of daily living by 0.3%, and worse living conditions and mobility by 0.4%.Conclusions: Improving DNT is a key factor in achieving good outcomes after stroke. We estimate that in Sweden alone in 2017, compared with 2010, the shorter DNT achieved have saved 38 lives, avoided 8 intracerebral hemorrhagic transformations, and spared, respectively, 36, 51, and 52 patients from a worsening in activities of daily living, living conditions, and mobility. DNT is sensitive for interventions and should be targeted in quality improvement efforts.

The impact of organizational and temporal factors on acute stroke care in Sweden
- 2020

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Acute stroke carries a high risk of morbidity and death, but early treatment can improve outcomes. Intravenous stroke thrombolysis (IVT) is one such treatment, it is however time-sensitive and show better outcomes the sooner it is given. Most studies on time to IVT so far have looked at fixed time-intervals, and studies of short delays in clinical practice are relatively scarce. Another well-established treatment is managing acute stroke patients in stroke units (SU). Admission rates to a SU as first destination of hospital care have improved over time in Sweden. In the past decade however, the rates have leveled out at around 75-80% without further improvement. A hypothesis is that in-hospital overcrowding contributes. Previous studies have shown that outcomes after stroke differ between hospital types, and also vary depending on time of admission, with higher mortality seen for off-hours, weekend and winter admissions. The reasons behind temporal variations are not fully understood, but it has been proposed that environmental, patient-related and organizational factors contribute. The overall aim of this thesis was to study the effect of organizational factors on quality of care and outcomes after stroke, primarily focusing on the role of in-hospital overcrowding, in-hospital time to IVT and time of admission, while also studying differences between hospitals.Methods: All papers in this thesis were based on data from the Swedish stroke register (Riksstroke), a national quality register that holds data on patient related factors, acute care and outcomes. Paper I included 13,955 patient admissions from 14 hospitals in Region Norrbotten and Region Skåne from 2011-2014, enriched with data on in-hospital bed occupancy. Papers II-IV included all 72 Swedish hospitals caring for patients with acute stroke. Paper II included data from 2011-2015 (N=113,862), paper III from 2011-2016 (N=132,744) and paper IV from 2010-2017 (N=14,132). Analyses included descriptive statistics, unadjusted analyses and multivariable adjusted analyses.Results: We found that each percent increase in in-hospital bed occupancy above 85% decreased admission rates to a SU as first destination of hospital care by 1.5% (odds ratio (OR) 0.985, 95% confidence interval (CI) 0.978-0.992), with significant differences between hospitals. Admission rates were also lower off-hours, compared to on-hours (OR 0.73, 95% CI 0.70-0.75). Over time, admission rates to a SU as first destination of hospital care decreased in university hospitals, while they increased in specialized non-university hospitals and community hospitals. Each minute delay in door-to-needle time (DNT) decreased the odds of 90-day survival by 0.6% (OR 0.994, 95% CI 0.992-0.996), increased the odds of ICH within 36 hours by 0.3% (OR 1.003, 95% CI 1.000-1.006), and led to significantly higher odds of a worsening in functional outcomes at 3 months by 0.3-0.4%. DNT within 30 minutes was most likely daytime, and varied between hospital types. 90-day survival was lowest for patients admitted in January (81.5%), and highest for those admitted in May (84.1%) (OR 1.28, 95% CI 1.17-1.40).Conclusion: We found that in-hospital overcrowding decrease admission rates to a SU as first destination of hospital care, and that even short delays in DNT decreases survival, increases ICH complications and leads to a worsening in functional outcomes in routine clinical practice. We also found that quality of care varied depending on time of admission and between hospitals, indicating unequal care. Organizational differences should be accessible through quality improvement efforts aiming to implement robust local guidelines for in-hospital stroke treatment.

Tidskriftsartikel (refereegranskat)abstract
- AIMS: Visual information about subclinical atherosclerosis was provided to physicians and participants in the VIPVIZA trial, inclusion 2013-16 in northern Sweden, aiming to improve adherence to cardiovascular disease (CVD) prevention guidelines. Pictorial risk information may be more actionable. The aim of this study was to investigate the effect of intervention with pictorial risk information on time to first dispensing of statins.METHODS AND RESULTS: Asymptomatic atherosclerotic disease was screened for by carotid ultrasound examination in 3532 participants enrolled in VIPVIZA, of those 3000 met the criteria for this study. Participants were randomly assigned to receive pictorial risk information consisting of graphical representation of atherosclerosis as compared to a control group without intervention. Time to initiation of statins was assessed during 5 years of follow-up through the National prescribed drug register. After 3 years, both groups were re-examined and received the intervention information. In the intervention group, initiation of statins increased considerably for the first 3 years and a smaller increase was also seen after re-intervention. After the cross-over, the control group showed a sharp increase in initiation of statins, almost reaching the same proportion treated at 5 years. The propensity to initiate statin treatment increased over the study period and there was no difference between men and women.CONCLUSIONS: The pictorial information had an effect on time to initiation of statins, both as original and repeated intervention and also in the control group after single-arm cross-over. The current study supports pictorial information as a tool to shorten time to initiation of statins for CVD prevention.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Medication-related hospital admissions (MRAs) are common among older people. Persons with cognitive impairment are especially vulnerable to adverse drug effects. At the same time, increased home health care and social support could theoretically prevent medication-related problems. This study aims to estimate the proportion of MRAs and explore their relationship with cognitive impairment in a population of acutely admitted older people.Methods: This cross-sectional study comprised 300 individuals aged 75 years or older admitted to an acute medical ward. Two assessors identified possibly MRAs using the Assessment Tool for Hospital Admissions Related to Medications 10 (AT-HARM10). Screening for cognitive impairment was performed during ward stay using a 4-item test related to time orientation. Prevalence odds ratios between cognitive test scores and MRAs were analysed through logistic regression.Results: Using AT-HARM10, 108 out of 300 admissions (36%) were classified as possibly MRAs by both assessors. Moreover, MRAs were least common among patients with the lowest cognitive test scores. There was an association regarding MRAs when the lowest test score was treated as a cut-off and compared against a reference category comprising all other scores (OR, 0.31 [95% CI 0.10–0.93]; p = 0.037) in a logistic regression model adjusted for cohabitation and home health care.Conclusion: Approximately one-third of the hospital admissions among acutely admitted older people were considered at least possibly medication-related. Hence, there is still a great need to manage medication-related problems and reduce MRAs in this vulnerable population. Using a 4-item instrument to screen for cognitive impairment, there was a negative association between MRA and lowest cognitive test score. Further exploration of the relationship between MRAs and cognitive impairment may indicate appropriate components and target populations for interventions that aims to reduce the risk of MRA.

Investigating the effect of clinical pharmacist intervention in transitions of care on drug-related hospital readmissions among the elderly : study protocol for a randomised controlled trial
- 2020
-
Ingår i: BMJ Open. - : BMJ Publishing Group Ltd. - 2044-6055. ; 10:4
-
Tidskriftsartikel (refereegranskat)abstract
- Introduction: Drug-related problems (DRPs) are a major cause of unplanned hospital admissions among elderly people, and transitions of care have been emphasised as a key area for improving patient safety. We have designed a complex clinical pharmacist intervention that targets people >= 75 years of age undergoing transitions of care from hospital to home and primary care. The main objective is to investigate if the intervention can reduce the risk of unplanned drug-related readmission within the first 180 days after the person is discharged from hospital.Methods and analysis: This is a randomised, controlled, superiority trial with two parallel arms. A total of 700 people >= 75 years will be assigned to either intervention or routine care (control). The intervention, which aims to find and manage DRPs, is initiated within a week of the person being discharged from hospital and combines repeated medical chart reviews, phone interviews and in some cases medication reviews. People in both study arms may have been the subject of a medication review during their ward stay. As the primary outcome, we will measure time until unplanned drug-related readmission within 180 days of leaving hospital and use log rank tests and Cox proportional hazard models to analyse differences between the groups. Further investigations of subgroup effects and adjustments of the regression models will be based on heart failure and cognitive impairment as prognostic factors.Ethics and dissemination: The study has been approved by the Regional Ethical Review Board in Umea (registration numbers 2017-69-31M, 2018-83-32M and 2018-254-32M). We intend to publish the results with open access in international peer-reviewed journals and present our findings at international conferences. The trial is expected to result in more than one published article and form part of two PhD theses.

Medication-related problems and psychotropic drug use in vulnerable older populations : a focus on acute hospital admissions and cognitive impairment
- 2023
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The ageing process involves several physiological changes that affect both pharmacodynamics and pharmacokinetics and that, in combination with a heavier disease burden and more extensive use of medicines, put older people at higher risk of medication-related problems and associated clinical outcomes. The older population is often treated as a homogenous group, when in fact there are factors that render certain individuals more vulnerable to adverse drug effects and other types of medication-related problems. Older people encountered in the acute medical care setting and/or individuals with varying degrees of cognitive impairment are especially vulnerable in that context. The overall aim of this thesis was to describe and understand medication use in certain vulnerable subgroups of older people, which in turn might identify suitable target populations in which medication-related problems can be prevented or managed through interventions or similar efforts.Paper I presented, in the form of a study protocol, a clinical pharmacist intervention intended to reduce the risk of medication-related readmission to hospital among people aged 75 years or older during transitions of care. Based on 300 participants from the intervention study, approximately 50% had been readmitted to hospital within 180 days of being discharged from the hospital. Both heart failure and cognitive impairment, the latter identified through a four-item test, were predictors of early readmission. Altogether, the study population seems relevant for the purpose of the intervention; whether the intervention model is effective remains to be determined.Based on the same sample of study participants, paper II found that approximately one third of the 300 index hospital admissions were possibly medication related. Moreover, possibly medication-related hospital admissions were negatively associated with the fewest positive/correct answers on the four-item screening tool for cognitive impairment, which suggests that those clinical events might be less prevalent among people with cognitive impairment when exploring the association cross-sectionally. Both papers III and IV were registry-based studies, and their overall objective can be summarized as to describe psychotropic drug use and associated factors among older people with major neurocognitive disorder (NCD). Paper III focused on differences between major NCD subtypes, whereas paper IV compared people with major NCD against matched references from the total older population. In brief, overall psychotropic drug use was notably higher among people with major NCD, although generally in line with national treatment guidelines in terms of individual drugs of choice. The use of hypnotic drugs was also extensive in the reference group, and deprescribing efforts seem warranted, although longitudinal studies that focus on long-term use could provide a better picture of the potential problem. Nursing home stay was also positively associated with psychotropic drug use for all classes of psychotropic drugs, and the difference was most prominent for antipsychotic drugs. In that context, over 1,200 people in the reference population, most of them nursing home residents, had filled prescriptions for antipsychotic drugs, a figure indicating that the management of neuropsychiatric symptoms might also be an issue among older people who, due to various circumstances, have not been examined and diagnosed with neurocognitive disorders. Regarding major NCD subtypes, individuals with Lewy body dementia had, except for antidementia drugs, higher odds of psychotropic drug use than did those with Alzheimer’s disease. For example, the odds of antipsychotic drug use were more than twice as high, which is a worrying figure given that people with Lewy body dementia are extremely sensitive to the adverse effects of those specific drugs.In conclusion, this thesis illustrates the heterogeneity of demographics and drug use among older people and indicates that certain types of medication-related problems may be more relevant in certain older subpopulations. Medicines appear to be involved in many hospital admissions of older people, and the acute medical setting and subsequent care transitions are likely an important focus of pharmaceutical interventions. However, psychotropic drugs are probably not a major issue in that specific context. Efforts to reduce psychotropic drug use are likely more relevant to people with major NCD, especially in the nursing home setting. Antipsychotic drug exposure among persons with Lewy body dementia could be one such focus, especially since there are other better-balanced pharmacological treatment options for these individuals in terms of efficacy and safety profile.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Psychotropic drugs are utilized against neuropsychiatric symptoms among people with major neurocognitive disorder (NCD) despite well-documented risks, and older people in nursing homes are expected to be more frequently exposed to those medicines. This study compared psychotropic drug use and associated factors between older people with major NCD and matched references.Methods: This cross-sectional study included individuals from three national registries in Sweden. References were randomly matched 1:1 by age and sex from the Swedish Total Population Register. Drug use was defined as at least one prescription fill from 1 July to 31 December 2019 and presented as proportion of drug users. In addition, ORs regarding psychotropic drug use and associated factors use were analysed using generalized estimating equations.Results: There were 102,419 complete matching pairs alive on 31 December 2019. The proportions of psychotropic drug users were 59% in the population of people with major NCD and 28% in the reference group. Moreover, there was a substantial number of individuals in nursing homes who had been treated with antipsychotics but who, for unknown reasons, had not been diagnosed with major NCD. Psychotropic drug use was positively associated with both major NCD and nursing home residency. The difference in drug use in relation to major NCD was more pronounced among people living in ordinary homes.Conclusion: Despite well-documented risks in people with cognitive impairment, psychotropic drug use was overall high and positively associated with both major NCD and nursing home residency. Taken together, interventions to better target neuropsychiatric symptoms in older people are warranted. Hypnotic drug use among older people in general as well as antipsychotic drug exposure among older people in nursing homes appear to be two important focus areas.

Tidskriftsartikel (refereegranskat)abstract
- Aims: Patient characteristics and treatment setting are potential predictors of premature dropout from lifestyle interventions, but their relative importance is unknown.Methods: From the quality registry of the unit for behavioral medicine, Umeå University hospital, we identified 2589 patients who had been enrolled in a multimodal lifestyle intervention for cardiometabolic risk reduction between 2006 and 2015. Baseline characteristics predicting dropout before 1-year follow-up were selected by a stepwise logistic regression algorithm.Results: Better physical health and older age predicted full participation, with odds ratios for premature dropout (ORs) of.44 (95% confidence interval (CI).31-.63), and.47 (95% CI.34-.65) in the highest compared to the lowest quartile, respectively. Odds of premature dropout were also lower among female participants,.71 (95% CI.58-.89). Premature dropout was predicted by higher BMI, snuffing tobacco, and smoking, with ORs of 1.53 (95% CI 1.13-2.08) in the highest compared to the lowest quartile of BMI, 1.37 (95% CI 1.03-1.81) comparing snuff user with non-users and 2.53 (95% CI 1.79-3.61) comparing smokers with non-smokers. Odds ratio for premature dropout among inpatients compared with outpatients was.84 (95% CI.68-1.04).Conclusion: Higher risk at baseline predicts premature dropout.

Tidskriftsartikel (refereegranskat)abstract
- Background and aims: Many patients with prior intracerebral haemorrhage have indications for antithrombotic treatment with antiplatelet or anticoagulant drugs for prevention of ischaemic events, but it is uncertain whether such treatment is beneficial after intracerebral haemorrhage. STudy of Antithrombotic Treatment after IntraCerebral Haemorrhage will assess (i) the effects of long-term antithrombotic treatment on the risk of recurrent intracerebral haemorrhage and occlusive vascular events after intracerebral haemorrhage and (ii) whether imaging findings, like cerebral microbleeds, modify these effects.Methods: STudy of Antithrombotic Treatment after IntraCerebral Haemorrhage is a multicentre, randomised controlled, open trial of starting versus avoiding antithrombotic treatment after non-traumatic intracerebral haemorrhage, in patients with an indication for antithrombotic treatment. Participants with vascular disease as an indication for antiplatelet treatment are randomly allocated to antiplatelet treatment or no antithrombotic treatment. Participants with atrial fibrillation as an indication for anticoagulant treatment are randomly allocated to anticoagulant treatment or no anticoagulant treatment. Cerebral CT or MRI is performed before randomisation. Duration of follow-up is at least two years. The primary outcome is recurrent intracerebral haemorrhage. Secondary outcomes include occlusive vascular events and death. Assessment of clinical outcomes is performed blinded to treatment allocation. Target recruitment is 500 participants.Trial status: Recruitment to STudy of Antithrombotic Treatment after IntraCerebral Haemorrhage is on-going. On 30 April 2020, 44 participants had been enrolled in 31 participating hospitals. An individual patient-data meta-analysis is planned with similar randomised trials.
