- BACKGROUNDThe perception of cardiovascular risk factors is believed to be associated with a person's willingness to carry out lifestyle changes as well as their willingness to adhere to prescribed preventive medications. Little is known about whether these perceptions differ between statin users and those not using statins, including how these factors relate to health behaviours.PURPOSEThe objective was to investigate and compare the perceptions of known modifiable risk factors for cardiovascular disease in patients using statins with those of a non-treated population. One further objective was to investigate if statin use was associated with favourable health behaviours.METHODData about health, perception of the importance of cardiovascular risk factors and health behaviours were collected through questionnaires from 829 statin users and 629 non-statin users. Beliefs about risk factors were compared in univariate analyses, and four health behaviours were compared in multivariate regression models.RESULTSStatin users had better health behaviours in univariate analyses compared to non-statin users. Statin users rated lifestyle-related risk factors as more important contributors for the development of cardiovascular disease than non-statin users. In a multivariate model, statin use was associated with having better eating habits.CONCLUSIONPeople using statins are more concerned about cardiovascular risk factors compared to non-statin users. The behaviour of taking statins seems to be associated with favourable eating habits.

- Objectives: Statins are a lipid-lowering treatment, prescribed frequently to prevent cardiovascular events. The objective of this study was to explore how doctors anticipate the effect of statins and what factors are associated with their willingness to initiate treatment. Methods: A total of 330 Swedish cardiologists, internists and general practitioners were asked to consider two hypothetical patient cases, one with and one without previous coronary heart disease. Based on these cases, the respondents answered questions about their willingness to initiate treatment and what effects they might expect. The expectation of effect was assessed in two ways: (1) the absolute risk reduction of myocardial infarction in 1000 patients treated with statins for 5 years; and (2) statins' average effect on increased life expectancy. The doctors' beliefs about absolute risk reduction were compared with results from clinical trials. Results: Most doctors had a suboptimal expectation about absolute risk reduction; only about one-third had expectations in the range supported by evidence-based data. There were different views about statins' ability to prolong life: that is, average gain in life expectancy due to treatment was believed to be 2 years in the primary patient case, and 3 years in the second patient case. The doctors' beliefs about statins' ability to prolong life were associated significantly with their willingness to initiate treatment. Conclusion: The overall results imply that doctors have varying and suboptimal understanding of the effect of statins. This may inhibit the goal of integrating clinical research into clinical practice.

Power of the Pill : Views about Cardiovascular Risk and the Risk-reducing Effect of Statins
- 2010

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Medical treatments with statins are prescribed to patients with increased risk of cardiovascular events. The benefits from statin treatment are well documented in clinical trials, but long-term adherence in patients is low, indicating that patients have an uncertainty about the necessity and benefits of treatment. The aims of this thesis were to investigate how patients and doctors view different aspects of statin treatment. Further aims were to investigate if the cardiovascular risk level in patients affects their views about different aspects of statin treatment. Yet further aims were to compare health behaviours and views about risk factors in patients using statins to a non-treated population. Data was obtained from patients (n = 829), doctors (n = 330) and a population sample (n = 720) using postal questionnaires. Views about the effect of statin treatment were assessed in different ways for patients and doctors. Patients based their assessments on their own situation, and doctors’ treatment decisions and assessments of anticipated effect of treatment were based on two hypothetical patient cases. The results indicate that patients greatly overestimate the general effect of statins, compared to efficacy results reported from clinical trials. Patients’ previous coronary heart disease or high overall risk were factors not associated with their views and expectations of treatment effect. Statin users with an internally perceived health control and patients satisfied with their doctor’s treatment explanation reported higher beliefs in treatment necessity and benefits. Statin users reported having better health behaviours and generally rated risk factors as more important than the non-treated population. Doctors had suboptimal understanding of the number of patients expected to benefit following five years of statin treatment and had a varying understanding of statins’ ability to prolong life. Overall the results illustrate that patients and doctors have different perspectives and views of the benefits from statin treatment which puts emphasis on how statin treatment is discussed in the clinical setting.

- BACKGROUNDPatients with dyslipidemia and high overall risk of ischemic heart disease are those most likely to benefit from treatment with statins. The objective of this study was to investigate patients' views of the necessity, harm, and expected benefits of their statin treatment, as well as factors associated with these treatment beliefs. One main objective was to investigate whether cardiovascular risk level and previous coronary heart disease affect the way patients view these different aspects of their medication.METHODSA total of 829 statin users were recruited while visiting a pharmacy to collect their statin medication (response rate, 69.4%). Patients returned a questionnaire assessing their medical history, concurrent risk status, social demographic factors, as well as their views and expectations regarding their statin treatment. RESULTS: Previous ischemic heart disease, or high risk of such disease, was not associated with a more favorable notion on statin treatment. Having an internal health locus of control as well as being satisfied with the physician's treatment explanation were factors associated with more positive views on expected treatment effect. The views on necessity, harm, and treatment benefit were closely associated with each other.CONCLUSIONThe main findings in this study suggest that cardiovascular risk level and previous coronary heart disease are not associated with the way patients value potential benefits of statin treatment. Patients' views of the treatment's necessity, harm, and benefits do not seem to be independent dimensions of patient beliefs but rather represent one overall question: is this good for me?

- BACKGROUNDInternational research shows that there is a higher use of care among the unemployed than among the employed, although the findings on the association between unemployment and healthcare use are not conclusive.PURPOSETo examine the association between healthcare use and employment status and the factors influencing this relationship.METHODDuring 2002, a questionnaire was sent to 1,000 persons who had recently registered as unemployed (participation rate: n = 570) and to a sample of 1,000 persons representing the Swedish population (participation rate: n = 641). The study design was cross-sectional. Persons still unemployed or otherwise not employed (n = 416) were compared with the employed (n = 414) using logistic regression analyses.RESULTSAbout half of those in the unemployed group had contacted a physician. The unemployed were also more likely to have needed but not sought care. Being in the unemployed group was a statistically significant risk factor for reporting unmet care needs, after adjusting for sociodemographic factors (OR = 1.53). The risk of abstaining from seeking care did not persist when considering economy and social network. Among those with unmet care needs, there was still a higher risk in the unemployed group of reporting: a small social network (OR = 2.73), economic hardship (OR = 2.87) and symptoms of depression (OR = 2.04).CONCLUSIONSUnemployment is a risk factor for both contacting a physician and for unmet care needs. A low social network and economic hardship are more present among persons who abstain from seeking healthcare and seem to be more common among the unemployed. The healthcare system should also be aware of the fact that some unemployed people with symptoms of depression abstain from seeking care.
