    Background Non-vitamin K antagonist oral anticoagulants (NOAC) have superior safety and comparable efficacy profile compared to vitamin-K antagonists (VKAs), with more convenient dosing schemes. However, issues with adherence to the NOACs remain unsolved. Aims We sought to investigate the adherence to oral anticoagulation (OAC) and baseline factors associated with poor adherence after ischaemic stroke in patients with atrial fibrillation (AF). Methods We recruited hospitalised patients (2013-2019) from two prospective stroke registries in Larissa and Helsinki University Hospitals and invited survived patients to participate in a telephone interview. We assessed adherence with the Adherence to Refills and Medications Scale (ARMS) and defined poor adherence as a score of over 17. In addition to demographics, individual comorbidities, and stroke features, we assessed the association of CHA(2)DS(2)-VASc and SAMe-TT2R2 scores with poor adherence. Results Among 396 patients (median age 75.0 years, interquartile range [IQR] 70-80; 57% men; median time from ischaemic stroke to interview 21 months [IQR 12-33]; median ARMS score 17 [IQR 17-19]), 56% of warfarin users and 44% of NOAC users reported poor adherence. In the multivariable regression model adjusted for site, sex, and age, poor adherence was independently associated with tertiary education, absence of heart failure, smoking history, use of VKA prior to index stroke, and prior ischaemic stroke. CHA(2)DS(2)-VASc and SAMe-TT2R2 scores were not associated with poor adherence. Conclusions Adherence was poor in half of AF patients who survived an ischaemic stroke. Independent patient-related factors, rather than composite scores, were associated with poor adherence in these patients. KEY MESSAGES Adherence was poor in half of the atrial fibrillation patients who survived an ischaemic stroke. Independent patient-related factors rather than composite scores were associated with poor adherence. The findings support the importance of recognising adherence support as a crucial part of holistic patient care recommended by recent AF guideline.

    Background: Mobile technology may help to better understand the adherence to treatment. MASK-rhinitis (Mobile Airways Sentinel NetworK for allergic rhinitis) is a patient-centred ICT system. A mobile phone app (the Allergy Diary) central to MASK is available in 22 countries. Objectives: To assess the adherence to treatment in allergic rhinitis patients using the Allergy Diary App. Methods: An observational cross-sectional study was carried out on all users who filled in the Allergy Diary from 1 January 2016 to 1 August 2017. Secondary adherence was assessed by using the modified Medication Possession Ratio (MPR) and the Proportion of days covered (PDC) approach. Results: A total of 12143 users were registered. A total of 6949 users reported at least one VAS data recording. Among them, 1887 users reported >= 7 VAS data. About 1195 subjects were included in the analysis of adherence. One hundred and thirty-six (11.28%) users were adherent (MPR >= 70% and PDC = 70% and PDC = 1.50) and 176 (14.60%) were switchers. On the other hand, 832 (69.05%) users were non-adherent to medications (MPR Conclusion and clinical relevance: Adherence to treatment is low. The relative efficacy of continuous vs on-demand treatment for allergic rhinitis symptoms is still a matter of debate. This study shows an approach for measuring retrospective adherence based on a mobile app. This also represents a novel approach for analysing medication-taking behaviour in a real-world setting.

    Many patients, especially those with a high pill burden and multiple chronic illnesses, are less adherent to medication. In medication treatments utilizing polypills, this problem might be diminished since multiple drugs are fused into one formulation and, therefore, the therapy regimen is simplified. This systematic review summarized evidence to assess the effect of polypills on medication adherence. The following databases were searched for articles published between 1 January 2000, and 14 May 2019: PubMed, Web of Science, Cochrane Library, and Scopus. Medication adherence was the only outcome assessed, regardless of the method of measuring it. Sixty-seven original peer-reviewed articles were selected. Adherence to polypill regimens was significantly higher in 56 articles (84%) compared to multiple pill regimens. This finding was also supported by the results of 13 out of 17 selected previously published systematic reviews and meta-analyses dealing with this topic. Adherence can be improved through the formulation of polypills, which is probably why the interest in researching them is growing. There are many polypills on the market, but the adherence studies so far focused mainly on a small range of medical conditions.

    Chronic myeloid leukemia (CML) is a malignant hematologic disorder, which is fatal without a treatment. Oral tyrosine kinase inhibitors (TKIs) have revolutionized the treatment of CML and transformed the disease to a chronic condition that can be treated at patient's home. The common problem in the treatment of CML is patient's poor adherence to TKIs. The regular, consistent use of TKIs is crucial to keep disease under control. For this reason and to obtain an optimal treatment outcome, adherence to TKIs is extremely important. The aim of the study was to assess reasons for poor adherence to TKI-medications in Finnish CMLpatients, including patient characteristics, treatment related factors, comorbidities and concomitant medications. In addition, patients' experiences, beliefs, knowledge and perception about CML and its treatment were explored and how these could contribute to nonadherent behaviour. This study is part of the larger study, assessing adherence to TKI treatment among Finnish CML population. The data was obtained by using patient questionnaires and semi-structured theme-interview during patient meetings in 2012. Study population consisted of Finnish adult CML patients who had been on TKI -medication (imatinib, nilotinib or dasatinib) for more than six months prior to the study baseline. Patients' adherence was measured using Morisky Medication Adherence 8-Item Scale (MMAS-8) and based on their score, patients were divided into three groups: high, medium and low adherence. Both quantitative and qualitative methods were used in data analysis. Study findings show that 21% (n=18) of the patients were low adherent and 23% (n=20) were high adherent to their treatment. Patient sociodemographic characteristics or experienced adverse drug reactions (ADRs) did not predict adherence, while more concomitant medications and comorbidities were associated with high adherence. However, ADRs had negative effect on the quality of life of several nonadherent patients. All nonadherent patients reported unintentional nonadherence and the most common reason was forgetting. Two-thirds of the patients (n=12) reported intentional nonadherence, which often was a result of experienced ADRs. The knowledge of CML and its treatment was poor among all patients while over half of the nonadherent patients (n=11) thought that they received enough information received. Overall, patients were very satisfied with care provided by the hospitals, physicians and other healthcare professionals. Managing TKI-treatment regimen is challenging for many patients and ADRs can have a negative impact on the quality of life. Healthcare professionals should regularly assess patient adherence and provide information and support for the patients to help them to succeed in medication management. Reasons for poor adherence are complex and have to be identified from each individual patient so that adherence can be improved.

    The results of this study showed the importance of autonomous motivation for healthy eating. Autonomous motivation and female gender were the determinants most strongly associated with fruits, vegetables, and berries intake among patients with type 2 diabetes. Other determinants of fruits, vegetables, and berries intake were high education, high social support, high age, and a strong sense of coherence. Autonomous motivation and self-care competence mediated the effect of perceived autonomy support from a physician on fruits, vegetables, and berries intake. Thus, physicians can promote patients' fruits, vegetables, and berries intake by supporting their autonomous motivation and self-care competence. The results are in line with self-determination theory.

    This study aims to address how easily an individual with no prior inhaler experience can learn to use a dry powder inhaler (DPI) through video education. This is a comparative study of four DPIs (Diskus, Easyhaler, Ellipta and Turbuhaler). Different properties affecting ease of use, patient preference as well as educational videos as a method of providing inhaler instructions were investigated. The study used a triangular methodology. The sample consisted of 31 individuals (24-35 years). All participants were considered inhaler naïve. After watching the video education material for a particular inhaler the participants' demonstrated the use of it. Educational videos for all four inhalers were watched and use of all placebo inhalers was demonstrated in a random order. These demonstrations were videotaped. The demonstrations were thereafter checked against a predefined checklist and all mistakes were recorded. Only 33 % of inhaler demonstrations were completed without the participants making any mistakes that could compromise the efficacy of the inhaled medication in a real-life situation. The frequency of error varied greatly between different types of inhalers. Ellipta proved to be most often used correctly with 55 % demonstrating use without making any mistakes. This was closely followed by Diskus for which 48 % demonstrated correct use. The difference between the average error frequency for Ellipta and Diskus was statistically insignificant. With Easyhaler 19 % percent of participants were able to demonstrate correct use, the corresponding percentage for Turbuhaler was 16 %. When comparing participants' demonstrations for Easyhaler and Turbuhaler, the difference in average error frequency between the devices were not statistically significant. The average frequency of error was lower when using Ellipta in comparison to Easyhaler and Turbuhaler (statistically significant). The same indications were found when comparing average frequency of error for Diskus, to those for Easyhaler and Turbuhaler. Comparing the participants self-reported correct use against the actual numbers it is clear that participants often thought they were using the inhaler correctly when they in fact were not. When asked to rank the inhalers from most preferred to least preferred, Ellipta emerged as a favorite. Turbuhaler received the second highest scores, Diskus the third and Easyhaler was least preferred. However, only the difference between preference scores for Ellipta and Easyhaler was deemed statistically significant. The high frequency of error suggests that even though participants generally considered the inhalers intuitive and easy to use, they would have required more comprehensive inhaler education in order to achieve correct inhaler technique. Further, the results indicate that video demonstrations are not ideal for providing inhaler education for first time inhalers users. The most prominent problem with video education is that it provides no feedback to the user regarding their inhaler technique. This may present real problems as the results of this study show that participants tended to overestimate their own inhaler technique. Patient education plays a central role in asthma care and needs to be given proper attention even though the inhalers might be considered intuitive and easy to operate. Interesting areas for future research include investigating interactive learning videos as a way of improving video education on inhaler technique.

    Objectives To explore adherence, persistence, and treatment patterns in patients with multiple sclerosis (MS) in Finland treated with disease-modifying therapies (DMTs) for active MS in 2005-2018. Materials and Methods The study cohort was identified using the Drug Prescription Register of Social Insurance Institute, Finland. All patients had at least one prescription of glatiramer acetate (GA), beta-interferons, teriflunomide, or delayed-release dimethyl fumarate (DMF). Adherence was calculated using proportion of days covered (PDC) (cutoff >= 0.8). Time to non-persistence was calculated by the number of days on index DMT treatment before the first treatment gap (>= 90 days) or switch and analyzed with time-to-event methodology. Results The cohort included 7474 MS patients (72.2% female; mean age 38.9 years). Treatment switches were steady over 2005-2012, peaked in 2015. PDC means (standard deviations) were GA, 0.87 (0.17); beta-interferons, 0.88 (0.15); DMF, 0.89 (0.14); teriflunomide, 0.93 (0.10). Adherence frequencies were GA, 78.4%; beta-interferons, 81.3%; DMF, 86.9%; teriflunomide, 91.7%. Logistic regression showed that age group, DMT and the starting year, sex, and hospital district independently affected adherence. Patients receiving teriflunomide and DMF, males, and older patients were more likely to persist on treatment. There was no difference in persistence between patients prescribed teriflunomide and DMF, or between GA and beta-interferons. Conclusions Oral DMTs had greater adherence and persistence than injectable DMTs.

    Sutterella species have been frequently associated with human diseases, such as autism, Down syndrome, and inflammatory bowel disease (IBD), but the impact of these bacteria on health still remains unclear. Especially the interactions of Sutterella spp. with the host are largely unknown, despite of the species being highly prevalent. In this study, we addressed the interaction of three known species of Sutterella with the intestinal epithelium and examined their adhesion properties, the effect on intestinal barrier function and the pro-inflammatory capacity in vitro. We also studied the relative abundance and prevalence of the genus Sutterella and Sutterella wadsworthensis in intestinal biopsies of healthy individuals and patients with celiac disease (CeD) or IBD. Our results show that Sutterella spp. are abundant in the duodenum of healthy adults with a decreasing gradient toward the colon. No difference was detected in the prevalence of Sutterella between the pediatric IBD or CeD patients and the healthy controls. Sutterella parvirubra adhered better than the two other Sutterella spp. to differentiated Caco-2 cells and was capable of decreasing the adherence of S. wadsworthensis, which preferably bound to mucus and human extracellular matrix proteins. Furthermore, only S. wadsworthensis induced an interleukin-8 production in enterocytes, which could be due to different lipopolysaccharide structures between the species. However, its pro-inflammatory activity was modest as compared to non-pathogenic Escherichia coli. Sutterella spp. had no effect on the enterocyte monolayer integrity in vitro. Our findings indicate that the members of genus Sutterella are widely prevalent commensals with mild pro-inflammatory capacity in the human gastrointestinal tract and do not contribute significantly to the disrupted epithelial homeostasis associated with microbiota dysbiosis and increase of Proteobacteria. The ability of Sutterella spp. to adhere to intestinal epithelial cells indicate that they may have an immunomodulatory role.

    End stage renal disease (ESRD) burdens both society and patient trough lower quality of life and the cost of treatment, as well as through lost productivity. In 2012, the incidence of ESRD was 81 patients per one million inhabitants in Finland. Annual number of kidney transplantations range from 150 to 210. The costs of specialized medical care, adherence to medication and health related quality of life (HRQoL) of kidney transplant patients were analyzed in this study. The aim of the study was to provide research to support the improvement of the kidney transplant patients' health care process and future research on the cost-effectiveness of kidney transplantation. In addition, the aim was to produce information to support health care decision making and resource allocation. The study population included 320 patients who had received a kidney transplant in HYKS. Of the included patients, 198 answered the questionnaire and 122 formed a control population of which only cost data was available. The cost data was collected from the HUS Ecomed-database. Medication adherence was measured with the BAASIS- and VAS-instruments and the HRQoL with the generic 15D-instrument. Forty-three per cent of the patients were non-adherent. There was no statistical difference in the adherence of patients with different dialysis modalities. The correct timing of taking the immunosuppressive medication proved to be its biggest challenge. The average quality of life for kidney transplant patients was measured at 0.87. There were no statistically significant differences in the 15D scores between adherent and non-adherent patients or different dialysis modalities. Instead, there were statistically significant differences between dialysis modalities in some of the 15 dimensions. The 15D score was on average lower among patients with a higher MRCI-score or a longer dialysis period prior to transplantation. The average cost for the specialized medical care of the kidney transplant patients was 34 331 euros on the year prior to the transplant, 52 834 euros one year after the transplant and 8 537 and 7 791 euros on the second and third year after the transplant, respectively. Average costs for all three years after the transplantation combined were 68 932 euros. Based on the results of this study, non-adherence to medication proved to be a considerable issue for kidney transplant patients. The HRQoL after a kidney transplantation was moderately high, although lower than in the age standardized general population. Adherence to medication, HRQoL or the dialysis modality were not associated with cost of the specialized medical care after the kidney transplantation and there was no single factor associated with these post transplant costs. The strength of the study is a comprehensive longitudinal analysis of special care costs and the factors associated with them. On the other hand, health related quality of life is only measured once, which is a limitation. The cost analysis would have been more comprehensive if all the health care cost and other direct costs such as travel and time cost as well as indirect costs such the loss of productivity had been included.

    Background: Therapist-supported, internet-delivered cognitive behavioral therapy (iCBT) is efficient in the treatment of depression. However, the optimal mode and intensity of therapist support remain to be identified. Scheduled telephone support (STS) may improve adherence and outcomes but, as it is time- and resource-consuming, should be reserved for patients for whom the usual support may be insufficient. Objective: This paper aims to reveal whether add-on STS for patients at risk of dropping out improves treatment adherence and symptoms in iCBT for depression. Methods: Among patients participating in an ongoing large observational routine clinical practice study of iCBT for depression delivered nationwide by Helsinki University Hospital (HUS-iCBT), those demonstrating a >= 14-day delay in initiation of treatment received invitations to this subsidiary STS study. A total of 100 consenting patients were randomly allocated to either HUS-iCBT as usual (control group, n=50) or HUS-iCBT plus add-on STS (intervention group, n=50). Proportions of those reaching midtreatment and treatment end point served as the primary outcome; secondary outcomes were change in Beck Depression Inventory (BDI)-measured depressive symptoms and time spent in treatment. Results: Add-on STS raised the proportion of patients reaching midtreatment compared with HUS-iCBT as usual (29/50, 58% vs 18/50, 36%; P=.045) and treatment end point (12/50, 24% vs 3/50, 6%; P=.02). Change in BDI score also favored add-on STS (3.63 points vs 1.1 points; P=.049), whereas duration of treatment did not differ. Conclusions: Add-on STS enhances adherence and symptom improvement of patients at risk of dropping out of iCBT for depression in routine clinical practice.

    Background: Mobile phone apps offer a promising medium to deliver psychological interventions. A mobile app based on Acceptance and Commitment Therapy (ACT) was developed and studied in a randomized controlled trial (RCT). Objective: To study usage metrics of a mobile ACT intervention and dose-response relationship between usage and improvement in psychological flexibility. Methods: An RCT was conducted to investigate the effectiveness of different lifestyle interventions for overweight people with psychological stress. This paper presents a secondary analysis of the group that received an 8-week mobile ACT intervention. Most of the analyzed 74 participants were female (n=64, 86%). Their median age was 49.6 (interquartile range, IQR 45.4-55.3) years and their mean level of psychological flexibility, measured with the Acceptance and Action Questionnaire II, was 20.4 (95% confidence interval 18.3-22.5). Several usage metrics describing the intensity of use, usage of content, and ways of use were calculated. Linear regression analyses were performed to study the dose-response relationship between usage and the change in psychological flexibility and to identify the usage metrics with strongest association with improvement. Binary logistic regression analyses were further used to assess the role of usage metrics between those who showed improvement in psychological flexibility and those who did not. In addition, associations between usage and baseline participant characteristics were studied. Results: The median number of usage sessions was 21 (IQR 11.8-35), the number of usage days was 15 (IQR 9.0-24), and the number of usage weeks was 7.0 (IQR 4.0-8.0). The participants used the mobile app for a median duration of 4.7 (IQR 3.2-7.2) hours and performed a median of 63 (IQR 46-98) exercises. There was a dose-response relationship between usage and the change in psychological flexibility. The strongest associations with psychological flexibility (results adjusted with gender, age, and baseline psychological variables) were found for lower usage of Self as context related exercises (B=0.22, P=.001) and higher intensity of use, described by the number of usage sessions (B=-0.10, P=.01), usage days (B=-0.17, P=.008), and usage weeks (B=-0.73, P=.02), the number of exercises performed (B=-0.02, P=.03), and the total duration of use (B=-0.30, P=.04). Also, higher usage of Acceptance related exercises (B=-0.18, P=.04) was associated with improvement. Active usage was associated with female gender, older age, and not owning a smart mobile phone before the study. Conclusions: The results indicated that active usage of a mobile ACT intervention was associated with improved psychological flexibility. Usage metrics describing intensity of use as well as two metrics related to the usage of content were found to be most strongly associated with improvement.
