  • Beliefs about medicines are strongly associated with medicine-use patterns among the general population
  • 2016

    • AimsTo investigate self-reported beliefs and perceived sensitivity to medicines and their effects in relation to self-reported use of medicines and herbal remedies. MethodsA survey sent to 13,931 randomly selected Swedish adults included the Beliefs about Medicines Questionnaire-General (BMQ-General) Questionnaire and the Perceived Sensitivity to Medicines Scale (PSM). The survey also asked about individuals' use of prescribed and over-the-counter (OTC) medicines and herbal remedies in the past month. We examined all associations between scores on the BMQ-General subscales and PSM in relation to the use of medicines and herbal remedies, using analysis of covariance adjusted for potential confounders. ResultsAmong 7099 respondents, those using herbal remedies exclusively believed strongly that prescription and OTC medicines are harmful and overprescribed. Respondents using prescription and OTC medicines reported more positive beliefs [coefficient 0.67 (95% CI 0.47-0.87) and 0.70 (95% CI 0.51-0.90)] on the benefits of medicines compared with those using herbal remedies [-0.18 (95% CI -0.57-0.20)]. Perceived sensitivity to medicines was higher among those using herbal remedies only [1.25 (95% CI 0.46-2.03)] compared with those using no medicines (reference 0) or prescription [-0.44 (95% CI -0.84 to -0.05)] or OTC [-0.27 (95% CI -0.66-0.12)] medicines alone. ConclusionRespondents using prescription and/or OTC medicines reported stronger positive beliefs about the benefits of medicines in general, supporting the hypothesis that beliefs influence medicine use. Therefore, addressing beliefs and concerns about medicines during patient counselling may influence medicine use, particularly regarding unintentional non-adherence.

  • Prevalence and perceived preventability of self-reported adverse drug events--a population-based survey of 7099 adults.
  • 2013
  • Ingår i: PloS one. - : Public Library of Science (PLoS). - 1932-6203. ; 8:9
  • Tidskriftsartikel (refereegranskat)abstract
    • Adverse drug events (ADEs) are common and often preventable among inpatients, but self-reported ADEs have not been investigated in a representative sample of the general public. The objectives of this study were to estimate the 1-month prevalence of self-reported ADEs among the adult general public, and the perceived preventability of 2 ADE categories: adverse drug reactions (ADRs) and sub-therapeutic effects (STEs).

  • Prevalence, nature and potential preventability of adverse drug events - A population-based medical record study of 4970 adults
  • 2014
  • Ingår i: British Journal of Clinical Pharmacology. - : Wiley-Blackwell. - 0306-5251 .- 1365-2125. ; 78:1, s. 170-183

    • AIMS: To estimate the 3-month prevalence of adverse drug events (ADEs), categories of ADEs, and preventable ADEs, and the preventability of ADEs among adults in Sweden. Further, to identify drug classes and organ systems associated with ADEs and estimate their seriousness.METHODS: A random sample of 5025 adults in Swedish county council in 2008 was drawn from the Total Population Register. All their medical records in 29 inpatient care departments in three hospitals, 110 specialised outpatient clinics, and 51 primary care units were reviewed retrospectively in a stepwise manner, and complemented with register data on dispensed drugs. ADEs, including adverse drug reactions (ADRs), sub-therapeutic effects of drug therapy (STEs), drug dependence and abuse, drug intoxications from overdose, and morbidities due to drug-related untreated indication, were detected during a 3-month study period, and assessed for preventability.RESULTS: Among included 4970 individuals, the prevalence of ADEs was 12.0% (95% confidence interval 11.1-12.9%), and preventable ADEs 5.6% (5.0-6.2%). ADRs (6.9%; 6.2-7.6%) and STEs (6.4%; 5.8-7.1%) were more prevalent than the other ADEs. Of the ADEs, 38.8% (35.8-41.9%) was preventable, varying by ADE category and seriousness. ADEs were frequently associated with nervous system and cardiovascular drugs, but the associated drugs and affected organs varied by ADE category.CONCLUSIONS: The considerable burden of ADEs and preventable ADEs from commonly used drugs across care settings warrants large-scale efforts to redesign safer, higher quality healthcare systems. The heterogeneous nature of the ADE categories should be considered in research and clinical practice for preventing, detecting and mitigating ADEs.

  • Influence of refill adherence method when comparing level of adherence for different dosing regimens
  • 2014
  • Ingår i: European Journal of Clinical Pharmacology. - : Springer Science and Business Media LLC. - 0031-6970 .- 1432-1041. ; 70:5, s. 589-597
  • Tidskriftsartikel (refereegranskat)abstract
    • To examine the impact of two methods when estimating refill adherence in patients using bisphosphonates with different dosing regimens. In the Swedish Prescribed Drug Register, 18,203 new users of bisphosphonates aged 18-85 years were identified between 1 July 2006 and 30 June 2007 and followed for a maximum of 2 years. The patients were categorised based on dosing regimen: one tablet daily, one tablet weekly, switching between these regimens, and other regimens. Refill adherence was estimated with Continuous measure of Medication Acquisition (CMA, adherent if CMA a parts per thousand yenaEuro parts per thousand 80 %) and the maximum gap method (adherent if gaps < 45 days). Differences in adherence between patients in the groups were assessed with logistic regression models controlling for confounding factors. The proportion of patients classified as adherent was higher using CMA compared with patients classified as adherent using the maximum gap method. Patients on one tablet weekly had significantly lower adherence compared with patients on one tablet daily in the main analyses of both methods (the maximum gap method: 73 % vs. 80 %; adjusted OR = 0.71; 95 % CI 0.57-0.89 and CMA: 84 % vs. 88 %, adjusted OR = 0.75; 95 % CI 0.57-0.99). Patients using the other two dosing regimens had significantly lower adherence compared with patients on one tablet daily using both methods. Choice of method has an impact on the estimates of refill adherence to bisphosphonates. Patients on one tablet weekly dosing had lower adherence compared with patients on one tablet daily dosing using both methods.

  • Adherence to Antihypertensive Therapy and Elevated Blood Pressure: Should We Consider the Use of Multiple Medications?
  • 2015
  • Ingår i: Plos One. - : Public Library of Science (PLoS). - 1932-6203. ; 10:9
  • Tidskriftsartikel (refereegranskat)abstract
    • Background Although a majority of patients with hypertension require a multidrug therapy, this is rarely considered when measuring adherence from refill data. Moreover, investigating the association between refill non-adherence to antihypertensive therapy (AHT) and elevated blood pressure (BP) has been advocated. Identify factors associated with non-adherence to AHT, considering the multidrug therapy, and investigate the association between non-adherence to AHT and elevated BP. A retrospective cohort study including patients with hypertension, identified from a random sample of 5025 Swedish adults. Two measures of adherence were estimated by the proportion of days covered method (PDC >= 80%): (1) Adherence to any antihypertensive medication and, (2) adherence to the full AHT regimen. Multiple logistic regressions were performed to investigate the association between sociodemographic factors (age, sex, education, income), clinical factors (user profile, number of antihypertensive medications, healthcare use, cardiovascular comorbidities) and non-adherence. Moreover, the association between non-adherence (long-term and a month prior to BP measurement) and elevated BP was investigated. Non-adherence to any antihypertensive medication was higher among persons < 65 years (Odds Ratio, OR 2.75 [95% CI, 1.18-6.43]) and with the lowest income (OR 2.05 [95% CI, 1.01-4.16]). Non-adherence to the full AHT regimen was higher among new users (OR 2.04 [95% CI, 1.32-3.15]), persons using specialized healthcare (OR 1.63, [95% CI, 1.14-2.32]), and having multiple antihypertensive medications (OR 1.85 [95% CI, 1.25-2.75] and OR 5.22 [95% CI, 3.48-7.83], for 2 and >= 3 antihypertensive medications, respectively). Non-adherence to any antihypertensive medication a month prior to healthcare visit was associated with elevated BP. Sociodemographic factors were associated with non-adherence to any antihypertensive medication while clinical factors with non-adherence to the full AHT regimen. These differing findings support considering the use of multiple antihypertensive medications when measuring refill adherence. Monitoring patients' refill adherence prior to healthcare visit may facilitate interpreting elevated BP.

  • A comparison of two methods for estimating refill adherence to statins in Sweden: the RARE project
  • 2011
  • Ingår i: Pharmacoepidemiology and Drug Safety. - : John Wiley and Sons. - 1053-8569 .- 1099-1557. ; 20:10, s. 1073-1079
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose To analyse and compare refill adherence to statins estimated with two different methods with a focus on sensitivity to definitions. less thanbrgreater than less thanbrgreater thanMethods Individuals aged 18-85 years who filled a statin prescription for the first time in 1.5 years during 1 January-30 June 2007 were followed until emigration or death or until 2 years after their first statin purchase. The data were collected via linkage between the Swedish Prescribed Drug Register, the National Patient Register and the Total Population Register. Days supply was estimated based on amount dispensed and prescribed dosage. Refill adherence was estimated with the continuous measure of medication acquisition (CMA) and the maximum gap method (cut-off 45days). The impact of altering definitions, for example, regarding hospitalisations, length of observation period and management of overlapping supply, was analysed. less thanbrgreater than less thanbrgreater thanResults The study included 36661 individuals (mean age 64 years, 47% women). The median proportion of days with statins was 95%, and 76% were classified as adherent with a cut-off at andgt;= 80% with CMA. With the maximum gap method, 65% were adherent. Disregarding hospitalisations did not alter the results. Emigration or death at least one year after statin initiation was associated with a lower adherence with both methods, and a shorter observation period and adding overlapping supply to the subsequent prescription increased the adherence estimates. less thanbrgreater than less thanbrgreater thanConclusions The choice of method and definitions, particularly regarding the management of overlapping supplies and the length of observation period, has a substantial impact on estimates of refill adherence to statins.

  • Is the level of patient co-payment for medicines associated with refill adherence in Sweden?
  • 2014
  • Ingår i: European Journal of Public Health. - : Oxford University Press (OUP). - 1101-1262 .- 1464-360X. ; 24:1, s. 85-90
  • Tidskriftsartikel (refereegranskat)abstract
    • In the Swedish reimbursement scheme, the co-payment is based on the price of the product and decreases in a stepwise manner as the total accumulated co-payment increases. The aim of this study was to analyse how refill adherence in Sweden varies according to patient's co-payment level for medicines, with antiepileptic drug (AED) use as an example.

  • Pharmacoepidemiology at Nordic School of Public Health NHV: Examples from 1999 to 2014
  • 2015
  • Ingår i: Scandinavian Journal of Public Health. - : SAGE Publications. - 1403-4948 .- 1651-1905. ; 43:16 Suppl, s. 73-80
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Pharmacoepidemiology is a branch of public health and had a place at the Nordic School of Public Health. Courses, Master's theses and Doctorates of Public Health (DrPH) in Pharmacoepidemiology were a relatively minor, but still important part of the school's activities. Methods: This paper gives a short background, followed by some snapshots of the activities at NHV, and then some illustrative case-studies. These case-studies list their own responsible co-authors and have separate reference lists. Results: In the Nordic context, NHV was a unique provider of training and research in pharmacoepidemiology, with single courses to complete DrPH training, as well as implementation of externally-funded research projects. Conclusions: With the closure of NHV at the end of 2014, it is unclear if such a comprehensive approach towards pharmacoepidemiology will be found elsewhere in the Nordic countries.
