A theory-based intervention to promote medication adherence in patients with rheumatoid arthritis: A randomized controlled trial

Introduction/objectives

Adherence to prescribed medication regimens is fundamental to the improvement and maintenance of the health of patients with rheumatoid arthritis. It is therefore important that interventions are developed to address this important health behavior issue. The aim of the present study was to design and evaluate a theory-based intervention to improve the medication adherence (primary outcome) among rheumatoid arthritis patients.

Methods

The study adopted a pre-registered randomized controlled trial design. Rheumatoid arthritis patients were recruited from two University teaching hospitals in Qazvin, Iran from June 2018 to May 2019 and randomly assigned to either an intervention group (n = 100) or a treatment-as-usual group (n = 100). The intervention group received a theory-based intervention designed based on the theoretical underpinnings of the health action process approach (HAPA). More specifically, action planning (making detailed plans to follow medication regimen), coping planning (constructing plans to overcome potential obstacles that may arise in medication adherence), and self-monitoring (using a calendar to record medication adherence) of the HAPA has been used for the treatment. The treatment-as-usual group received standard care.

Results

Data analysis was conducted based on the principle of intention to treat. Using a linear mixed-effects model (adjusted for age, sex, medication prescribed, and body mass index), the results showed improved medication adherence scores in the intervention group (loss to follow-up = 16) compared to the treatment-as-usual group (loss to follow-up = 12) at the 3-month (coefficient = 3.9; SE = 0.8) and 6-month (coefficient = 4.5; SE = 0.8) follow-up. Intervention effects on medication adherence scores were found to be mediated by some of the theory-based HAPA variables that guided the study.

Conclusion

The results of the present study support the use of a theory-based intervention for improving medication adherence among rheumatoid arthritis patients, a group at-risk of not adhering to medication regimens.

Patients' and Doctors' Beliefs about Treatment and Long-Term Adherence in Rheumatic Diseases

Objective:

The aim of this study was to explore the beliefs of rheumatologists and patients about treatment-related factors, long-term adherence, and their communication with regard to rheumatic diseases.

Methods:

In a multicentre, observational study conducted in Greece, a structured questionnaire was administered to 75 rheumatologists and 398 rheumatic patients from different regions. Five domains were investigated: i) effectiveness of treatment, ii) choice of treatment, iii) change of ineffective treatment, iv) long-term adherence, and v) the quality of communication between doctors and patients. Descriptive data, confidence intervals, t-tests and factor analysis were employed.

Results:

Examining the patients’ and rheumatologists’ beliefs and attitudes about treatment profiles and long-term adherence, a statistically significant convergence in their views on effectiveness and safety as the predominant factors concerning choice of treatment and long-term adherence was found. Although patients reported high trust to their doctors, a divergence of views is recorded regarding communication of the two parts. Statistically significant differences in the views between patients and rheumatologists were found with regards to access (p<0.001), time per visit (p<0.001), mutual understanding (p<0.001), and overall communication (p<0.001).

Conclusions:

Our study shows a great rate of agreement between patients and rheumatologists regarding the factors determining the efficacy, choice, switching and adherence to treatment while there was significant divergence in the views regarding the quality of communication between the two parts. Co-ordinated efforts are needed in order to improve the communication level between rheumatic patients and rheumatologists.

Directly observed hepatitis C treatment with opioid substitution therapy in community pharmacies: A qualitative study

BACKGROUND

The hepatitis C virus (HCV) will only be eliminated through successful engagement with people who inject drugs (PWID), however some of this population experience socioeconomic and individual issues that can lead to poor HCV treatment adherence. A key sub-group of (PWID) are those who receive opioid substitution therapy (OST). In Australia, OST is most often delivered under direct supervision by a community pharmacist every day or multiple times a week. This regular interaction could be an ideal opportunity to enhance direct-acting antiviral (DAA) treatment adherence under directly observed therapy (DOT) by the pharmacist.

AIM

The aim of this study was to explore the perspectives of OST patients with a lived experience of HCV to understand whether or not dispensing DAAs in the same way as, or simultaneously with OST would benefit HCV treatment.

METHODS

Data collection occurred from June to August 2017. Semi-structured interviews were conducted with a sample of PWID living with HCV and on OST programs (n = 12) in Melbourne, Australia. Interviews were voice recorded and transcribed in verbatim. Interpretive phenomenology guided analysis of the data.

RESULTS

Themes reported by participants that provide insight into the suitability of DOT of DAAs include: Adherence and non-adherence to DAA treatment; Mixed views towards DOT of DAAs; Experiences and perceptions of OST providers; and Perceived stigma in the pharmacy.

CONCLUSIONS

Community pharmacies offering OST may be an effective place for DOT of HCV treatment, but is likely only to benefit people who face significant challenges to adherence. We suggest that a positive pharmacist-patient relationship, high OST adherence, and commitment to reducing stigma in the pharmacy would be necessary for the intervention to be effective. Further research is needed to evaluate the expanded-role of community pharmacies in improving DAA adherence and eliminating HCV.

Contrasting implicit and explicit measures of attitudes to complementary and alternative medicines

We aimed to contrast implicit and explicit measures of attitudes towards complementary and alternative medicines, to determine which best predicts medicine adherence. 117 participants from Université Grenoble Alpes completed online measures of attitudes towards complementary and alternative medicines, including implicit measures (Affect Misattribution Procedure (AMP); Implicit Association Test (IAT)), and explicit measures (Beliefs about Medicines Questionnaire (BMQ), modified explicit AMP); and self-reported medicine adherence (Medication Adherence Scale (MARS); Probabilistic Medication Adherence Scale (ProMAS)). AMP measures of implicit and explicit attitudes predicted beliefs toward medicine and medicines adherence. Models including implicit measures were stronger than models with explicit measures alone. Further, the AMP predicted beliefs toward medicine as well as medicine adherence, and the AMP was a stronger predictor compared to the IAT, although the IAT predicted adherence. These preliminary findings suggest that 'hot' implicit attitudes are a useful predictor of people's medicine choices, and that the AMP outperforms the IAT.

Patients' perspectives on antiepileptic medication: relationships between beliefs about medicines and adherence among patients with epilepsy in UK primary care

BACKGROUND

Nonadherence to antiepileptic drugs (AEDs) can result in suboptimal outcomes for patients.

AIM

This study aimed to assess the utility of a theory-based approach to understanding patient perspectives on AEDs and adherence.

METHOD

Patients with epilepsy, identified by a GP case note review, were mailed validated questionnaires assessing their perceptions of AEDs and their adherence to them.

RESULTS

Most (84.9%) of the 398 AED-treated respondents accepted the necessity of AEDs, but over half expressed doubts, with 55% disagreeing or uncertain about the statement 'I would prefer to take epilepsy medication than risk a seizure'. Over a third (36.4%) expressed strong concerns about the potential negative effects of AEDs. We used self-report and medication possession ratio to classify 36.4% of patients as nonadherent. Nonadherence was related to beliefs about medicines and implicit attitudes toward AEDs (p<0.05). Adherence-related attitudes toward AEDs were correlated with general beliefs about pharmaceuticals (BMQ General: General Harm, General Overuse, and General Benefit scales) and perceptions of personal sensitivity to medicines (PSM scale).

CONCLUSION

We identified salient, adherence-related beliefs about AEDs. Patient-centered interventions to support medicine optimization for people with epilepsy should take account of these beliefs.
