Abstract
BACKGROUND Non-adherence to medication is a common and complex issue faced by individuals undergoing hemodialysis (HD). However, more knowledge is needed about modifiable factors influence on non-adherence. This study investigated the prevalence of non-adherence, medication beliefs and symptom burden and severity among patients receiving HD in Denmark. Associations between non-adherence, medications beliefs and symptom burden and severity were also explored. METHOD A cross-sectional questionnaire-based multisite study, including 385 participants. We involved patient research consultants in the study design process and the following instruments were included: Medication Adherence Report Scale, Beliefs about Medication Questionnaire and Dialysis Symptom Index. Logistic regression analysis was performed. RESULTS The prevalence of non-adherence was 32% (95% CI 27-37%) using a 23-point-cut-off. Just over one third reported being concerned about medication One third also believed physicians to overprescribe medication, which was associated with 18% increased odds of non-adherence. Symptom burden and severity were high, with the most common symptoms being tiredness/ lack of energy, itching, dry mouth, trouble sleeping and difficulties concentrating. A high symptom burden and/or symptom severity score was associated with an increased odd of non-adherence. CONCLUSION The study found significant associations between non-adherence and, beliefs about overuse, symptom burden and symptom severity. Our results suggest health care professionals (HCP) should prioritize discussion about medication adherence with patients with focus on addressing patient-HCP relationship, and patients' symptom experience. Future research is recommended to explore the effects of systematically using validated adherence measures in clinical practice on medication adherence, patient-HCP communication and trust. Additionally, studies are warranted to further investigate the relationship between symptom experience and adherence in this population. TRIAL REGISTRATION NCT03897231.

Abstract
Background Measurement of serum concentrations of drugs is a novelty found useful in detecting poor drug adherence in patients taking ≥2 antihypertensive agents. Regarding patients with treatment-resistant hypertension, we previously based our assessment on directly observed therapy. The present study aimed to investigate whether serum drug measurements in patients with resistant hypertension offer additional information regarding drug adherence, beyond that of initial assessment with directly observed therapy. Methods and Results Nineteen patients assumed to have true treatment-resistant hypertension and adherence to antihypertensive drugs based on directly observed therapy were investigated repeatedly through 7 years. Serum concentrations of antihypertensive drugs were measured by ultra-high-performance liquid chromatography-tandem mass spectrometry from blood samples taken at baseline, 6-month, 3-year, and 7-year visits. Cytochrome P450 polymorphisms, self-reported adherence and beliefs about medicine were performed as supplement investigations. Seven patients (37%) were redefined as nonadherent based on their serum concentrations during follow-up. All patients reported high adherence to medications. Nonadherent patients expressed lower necessity and higher concerns regarding intake of antihypertensive medication (P=0.003). Cytochrome P450 polymorphisms affecting metabolism of antihypertensive drugs were found in 16 patients (84%), 21% were poor metabolizers, and none were ultra-rapid metabolizers. Six of 7 patients redefined as nonadherent had cytochrome P450 polymorphisms, however, not explaining the low serum drug concentrations measured in these patients. Conclusions Our data suggest that repeated measurements of serum concentrations of antihypertensive drugs revealed nonadherence in one-third of patients previously evaluated as adherent and treatment resistant by directly observed therapy, thereby improving the accuracy of adherence evaluation.

Usability and perceived usefulness of patient-centered medication reconciliation using a personalized health record: a multicenter cross-sectional study. BMC Health Serv Res 2022; 22:776. [PMID: 35698220 PMCID: PMC9195254 DOI: 10.1186/s12913-022-07967-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2021] [Accepted: 04/18/2022] [Indexed: 09/03/2023] Open
Abstract
BACKGROUND Adoption of a personal health record (PHR) depends on its usability and perceived usefulness. Therefore, we aimed to assess the usability and perceived usefulness of an online PHR used for medication reconciliation and to assess the association between patient-, clinical-, hospital-, and ICT-related factors and the usability and perceived usefulness at both the in- and outpatient clinics. METHODS A multicenter cross-sectional study was conducted with patients with either an outpatient visit (rheumatology ward) or planned admission in the hospital (cardiology, neurology, internal medicine or pulmonary wards). All patients received an invitation to update their medication list in the PHR 2 weeks prior to their appointment. One month after the hospital visit, PHR-users were asked to rate usability (using the System Usability Scale (SUS)) and perceived usefulness on a 5-point Likert scale. The usability and perceived usefulness were classified according to the adjective rating scale of Bangor et al. The usability was furthermore dichotomized in the categories: low (SUS between 0 and 51) and good (SUS 51-100) usability. Associations between patient-, clinical-, hospital-, and ICT-related factors and the usability and perceived usefulness were analysed. RESULTS 255 of the 743 invited PHR-users completed the questionnaire. 78% inpatients and 83% outpatients indicated that usability of the PHR was good. There were no significant association between patient-, clinical-, hospital-, and ICT-related factors and the usability of the PHR. The majority of the patients (57% inpatients and 67% outpatients) classified perceived usefulness of the PHR as good, excellent, or best imaginable. Outpatients who also used the PHR for other drug related purposes reported a higher perceived usefulness (adjusted odds ratio 20.0; 95% confidence interval 2.36-170). Besides that, there was no significant association between patient-, clinical-, hospital-, and ICT-related factors and the perceived usefulness of the PHR. CONCLUSIONS The majority of the patients indicated that the PHR for medication reconciliation was useful and easy to use, but there is still room for improvement. To improve the intervention, further research should explore patients' barriers and facilitators of using a PHR for medication reconciliation.

Abstract
To investigate adherence to immunosuppressive medication (IM) in kidney transplant recipients (KTRs) and analyze the associated factors using the Theory of Planned Behavior (TPB). Data were collected at Time1 (T1) and 3 months later (T2). T1: the elements of the TPB, past behavior, beliefs about medicines, perceived social support were measured. T2: IM adherence was measured. Structural equation modeling was applied to analyze the associated factors of medication adherence. A total of 246 KTRs were included. The average IM adherence score of KTRs' was 4.86 (SD = 1.63). Of the recipients, 39.43% had one aspect of non-adherence to IM. The model could explain 28.7% of the variance in adherence to IM (R2 = .287, p = .006). TPB is a useful tool for understanding adherence to IM in KTRs. Caregivers can provide effective interventions during follow-up, which should focus on improving medication beliefs as well as provision of other external support especially from outside.

Abstract
Adolescents diagnosed with chronic kidney disease (CKD) who undergo kidney transplantation have to adjust to pervasive effects of chronic illness and life-long treatment maintenance, alongside normative developmental stressors. The way in which adolescent transplant recipients experience and think about their illness as well as their medication regimen can be a crucial factor impacting psychosocial outcomes. Participants were 26 adolescent kidney transplant recipients (μ = 16.8 years, σ = 1.69 years) who completed self-report surveys during a clinic visit. Multiple linear regressions were used to investigate whether adolescents' beliefs about medications and attitudes and perceptions of their illness are associated with their overall quality of life. Adolescents' negative illness perceptions contributed to lower transplant-specific health-related quality of life ratings (ΔR2 =.305, p < .01). Additionally, adolescent beliefs about their specific medication regimens (ie, personal medication concerns) (ΔR2 =.342, p < .01), and general beliefs about medication use (ie, harm, overuse) (ΔR2 =.241, p < .05) also contribute significantly to the variance in their overall quality of life ratings. Adolescent transplant patients in older grades and those in special education endorsed lower quality of life. Cognitive components (eg, beliefs, perceptions) of an adolescent kidney transplant recipient's experience contribute to transplant-related quality of life outcomes. This highlights a point of intervention where cognitive change interventions may be utilized and efficacious in improving health outcomes.

Beliefs about immunosuppressant medication and correlates in a German kidney transplant population. J Psychosom Res 2020; 132:109989.

Abstract
OBJECTIVE A common reason for organ rejection after transplantation is the lack of adherence regarding immunosuppressive medication (ISM). A variety of different aspects can promote non-adherent behavior, including the relationship between perceived benefits and concerns regarding ISM ("necessity-concerns-framework"). Little is known about the variables associated with this framework. METHODS As part of this cross-sectional study, 570 patients after kidney transplantation who participated in a structured multimodal follow-up program (KTx360°) were examined in two transplant centers in Lower Saxony. We used the Beliefs about Medicines Questionnaire (BMQ) to evaluate the patients' believes and concerns regarding their ISM. RESULTS The mean age of the participants was 51.9 (SD 14.17) years, 58.4% were men, and 25.8% had ≥12 years of school attendance. The mean time since transplantation was 65.9 months. In patients undergoing kidney transplantation, the perceived benefit of ISM mostly exceeded the concerns. We found an association between lower perceived benefits and greater concerns and lower adherence. Also, a higher perceived necessity was significantly associated with higher age and lower levels of depression and anxiety. Greater concerns were significantly associated with more symptoms of depression and anxiety, lower perceived social support, and lower kidney functioning (eGFR). CONCLUSION Even though patients after kidney transplantation usually acknowledge the importance of their ISM, they still have considerable concerns that are associated with less adherence and various psychosocial risk factors. Further longitudinal studies are needed to assess the extent to which beliefs about medication are variable and can be individually addressed to improve adherence.
