Enhancing adherence through education

Effect of an educational intervention based on the theory of planned behavior on improving medication adherence in patients with multiple sclerosis treated with injectable disease-modifying drugs: randomized controlled trial

BACKGROUND

Adherence to prescribed treatment in chronic diseases, as occurs in multiple sclerosis (MS), is a critical factor for a successful therapeutic response. This study aimed to investigate the effect of educational program based on Theory of Planned Behavior (TPB) on treatment adherence in patients with multiple sclerosis (MS) receiving injectable immunomodulatory drugs.

METHODS

The present study is an educational randomized controlled trial research that was conducted on 100 patients with MS who had gone to MS clinic in Tehran city (Iran). The samples were randomly assigned to the intervention (N = 50) and control groups (N = 50). Data collection instrument was a researcher-made questionnaire based on TPB. Then, educational program was performed for the intervention group through four educational sessions. After three months, data collection was repeated for the two groups and data were analyzed.

RESULTS

The knowledge and performance of the intervention group on treatment adherence drugs increased from 56.25 ± 20.3 to 78.31 ± 15.57 and 56.22 ± 5.76 to 71.62 ± 12.01 after the education respectively (p < 0.001). The mean of construct of TPB in the intervention group also increased after the intervention (p < 0.05).

CONCLUSION

Applying the TPB model proved is very effective in developing an educational program for patients with MS, to enhance treatment adherence drugs. Besides such programs, follow-up education for controlling and monitoring are highly recommended.

Best Methods of Communicating Clinical Trial Data to Improve Understanding of Treatments for Patients with Multiple Sclerosis

BACKGROUND

Patients' understanding of treatment risks and benefits is a prerequisite for shared decision making. Yet, patients with multiple sclerosis (MS) do not accurately understand treatment information provided in regular clinical consultations.

OBJECTIVES

To identify the best methods of communicating clinical trial data to improve the understanding of treatments among patients with MS and to also examine the relationship between patients' understanding with decisional conflict, individual traits, and MS symptoms.

METHODS

A repeated-measures study was used. A sample of relapsing-remitting patients with MS was recruited from National Health Service sites in the United Kingdom. Patients were presented with hypothetical treatment risks and benefits from faux clinical trials. Treatments were communicated using absolute terms, relative terms, and numbers needed to treat/harm. The presence of baseline information with each method was also manipulated. Patients' understanding and conflict in treatment decisions were assessed. Individual traits and MS symptoms were also recorded.

RESULTS

Understanding was better when treatments were communicated in absolute terms (mean 3.99 ± 0.93) compared with relative terms (mean 2.93 ± 0.91; P < 0.001) and numbers needed to treat/harm (mean 2.89 ± 0.88; P < 0.001). Adding baseline information to all methods significantly improved understanding (mean 5.04 ± 0.96) compared with no baseline information (mean 1.50 ± 0.74; P < 0.001). Understanding was not related to conflict in treatment decisions (r = -0.131; P = 0.391). Numeracy, IQ, and cognitive impairments were significantly related to patients' understanding of treatments.

CONCLUSIONS

Treatment risks and benefits should ideally be communicated using absolute terms, alongside baseline information. Patients with MS with low numeracy, low IQ, and reduced cognitive skills should be supported during treatment education.

Comparative evaluation of patients' and physicians' satisfaction with interferon beta-1b therapy

Background

Due to the preventive nature of disease-modifying therapies for multiple sclerosis, treatment success particularly depends on adherence to therapeutic regimens and patients’ perception of treatment efficacy. The latter is strongly influenced by the confidence in the involved health care professionals and the relationship to the treating physician.

Methods

In this report, we considered physicians’ and patients’ evaluation of satisfaction with interferon beta-1b treatment efficacy for assessing the congruence in ratings. Data were queried in a study conducted between 2009 and 2013.

Results

After 6 months of therapy, > 80 % of the patients and physicians (N = 445) showed high degrees of satisfaction regarding interferon beta-1b treatment, with only few physicians and patients (≤2.0 %) rating “not satisfied”. The proportion of patients rating with the same category as their physicians was similar after 6 months (47 % congruence) and at the 24 months/study end visit (49 %). Discrepancies between ratings were observed with respect to study end: for patients with premature study end, more patients and physicians rated being not satisfied with the therapy, accompanied by a considerably lower congruence of 33 % compared to 54 % for patients receiving the therapy for at least 2 years and completing the study regularly.

Conclusions

Regular communication between physicians and patients about their perception of therapy might improve alignment of treatment evaluation and could result in increased therapy persistence. In addition, patients’ willingness to perform a long-term therapy − even in the absence of disease symptoms − might be promoted by repeated exchange between health care providers and patients with regard to realistic treatment expectations.

Adherence and cost in multiple sclerosis patients treated with IM IFN beta-1a: impact of the CARE patient management program

BACKGROUND

Disease modifying treatments (DMT) for MS such as interferon beta (IFNβ) have been shown to reduce the risk for disease progression. Therefore adherence to treatment is essential for treatment outcome.Here we want to evaluate if participation in a patient management program (PMP) improves adherence to DMT as well as health and cost outcomes associated with MS.

METHODS

In this open-label multicentre prospective observational study, German MS patients treated with once weekly intramuscular (IM) IFNβ-1a (Avonex), were offered participation in a PMP and followed for up to 12 months. The PMP included injection trainings, support and quarterly visits for up to 12 months after initiation of therapy. Utilisation of health care services was evaluated. The primary endpoint was to evaluate the direct and indirect cost associated with MS from payer, patient and societal perspective, in patients who participate in the PMP. Secondary endpoint was the clinical outcome in patients who participate in the PMP (differentiated in adherent versus non-adherent patients).

RESULTS

In total 731 patients (mean age: 38.2, 73.7% female) were enrolled, 640 (88%) were observed for twelve months. After six months 34% of patients had participated in the PMP continuously and 21% temporarily; 39% had not participated. After twelve months, the proportions of participants were: 37% continuously and 19% temporarily; 40% had not participated. After 6 months, mean reduction in cost per patient in the participants group (€ 2151) was almost twice as high as the cost reduction amongst non-participants (€ 1131). After twelve months, the annual relapse rate was reduced by 58% compared to baseline in both the participant and non-participant groups.

CONCLUSIONS

In a real-world-setting, participation in a patient management program was associated with improved medication adherence and lower total MS-related direct and indirect cost over time.

Treatment adherence in multiple sclerosis: a survey of Belgian neurologists

BACKGROUND

Poor treatment adherence is common among patients with multiple sclerosis (MS). This survey evaluated neurologists' perception of treatment adherence among MS patients.

MATERIALS AND METHODS

This questionnaire-based survey of Belgian neurologists treating MS patients was conducted between June and July 2014. Face-to-face interviews with the neurologists were based on a semistructured questionnaire containing questions regarding the perception of the treatment-adherence level.

RESULTS

A total of 41 neurologists participated in the survey. Of these, 88% indicated frequent discussions about treatment adherence as beneficial for treatment efficacy. The mean time spent on the treatment-adherence discussion during the initial consultation was 11 minutes, with 24% of doctors spending 5 minutes and 24% of doctors spending 10 minutes discussing this issue. The majority of neurologists (56%) perceived the adherence level in MS as good, and 12% perceived it as excellent. The majority of neurologists (64%) indicated intolerance as a main cause of poor adherence, and all neurologists reported insufficient efficacy as a consequence of nonadherence. The importance of adherence in the neurologists' practice was evaluated on a scale of 1-10, with 1= "not very important" and 10= "very important": 44% of doctors indicated a score of 10, and the mean score was 9.0.

CONCLUSION

Belgian neurologists consider treatment adherence in MS as essential for the benefits of therapies. However, although neurologists are aware of the consequences of nonadherence, they generally spend limited time discussing the importance of treatment adherence with their patients.

The care continuum in acromegaly: how patients, nurses, and physicians can collaborate for successful treatment experiences

Patients with acromegaly (a condition of chronic growth hormone hypersecretion by a pituitary adenoma) often require pharmacological treatment. Somatostatin analogs (SSAs) such as pasireotide, lanreotide, and octreotide are frequently used as first-line medical therapy. As SSAs are delivered by regular subcutaneous or intramuscular injections, they can result in injection-related pain or anxiety and can be challenging to fit into patients' lifestyles. When combined with the prolonged, debilitating psychological complications associated with acromegaly, these administration challenges can negatively impact compliance, adherence, and quality of life. Proactively managing patients' expectations and providing appropriate, timely guidance are crucial for maximizing adherence, and ultimately, optimizing the treatment experience. As part of ongoing clinical research since 1997, our team at the University of Michigan has used SSAs to treat 30 patients with acromegaly. Based on our clinical experiences with multiple SSA administration regimens (long-acting intramuscular, long-acting deep subcutaneous, and twice-daily subcutaneous), we generated a dialog map that guides health care professionals through the many sensitive and complex patient communication issues surrounding this treatment process. Beginning with diagnosis, the dialog map includes discussion of treatment options, instruction on proper drug administration technique, and ensuring of appropriate follow-up care. At each step, we provide talking points that address the following: the patients' clinical situation; their geographic, economic, and psychological concerns; and their inclination to communicate with clinicians. We have found that involving patients, nurses, and physicians as equal partners in the treatment process optimizes treatment initiation, adherence, and persistence in acromegaly. By encouraging collaboration across the care continuum, this dialog map can facilitate identification of the treatment plan that is most likely to yield the best possible outcome.

Adherence to disease-modifying therapies and attitudes regarding disease in patients with multiple sclerosis

Although currently there is no cure for MS the course of the disease can be influenced by disease modifying therapy (DMT). For therapy to be sufficiently efficient, it is crucial that patients take their medication regularly as prescribed. Adherence describes the extent to which a patient acts in accordance with the prescribed timing, dosing, and frequency of medication administration. To date, there are no known data about adherence rates among patients with MS in Slovenia. We wanted to assess adherence in patients with MS, who are treated with first line DMTs and discover reasons for non-adherence. A number of 451 patients were invited to participate. They received two questionnaires via post mail. The adherence rate and putative reasons for non-adherence were assessed by the use of standardized self-report Multiple Sclerosis Treatment Experience Questionnaire (MSTEQ). Patients' attitudes regarding disease, therapy and relationship with their physician were assessed by another questionnaire. The analysis of results included 299 patients. Among the patients 18.5% missed at least one medication dose in the past 28 days. Patients taking Avonex were significantly more adherent then patients on other DMTs (p=0.005). Our study showed a higher then expected adherence among Slovenian patients with MS (81.5%). Our research did not confirm the influence of side effects or patients' attitudes regarding illness and therapy on adherence. However we found unexpectedly high percentage (71.8%) of patients belief that psychological factors are involved in MS aetiology.

Assessing the role of patient support services on adherence rates in patients using glatiramer acetate for relapsing-remitting multiple sclerosis

OBJECTIVE

To assess predictors of achievement of 80% Medication Possession Ratio (MPR) in patients receiving manufacturer-provided self-management services for relapsing-remitting multiple sclerosis (RRMS) patients taking glatiramer acetate (Copaxone).

METHODS

De-identified patient records were selected for study inclusion if patients had been (1) continuously enrolled in one or more aspects of the self-management program for a minimum of 24 months and had adherence measured by MPR between the values of zero and one. Baseline patient univariate measures were assessed using chi-squared statistics for categorical variables and Analysis of Variance (ANOVA) for continuous variables. Bivariate logistic regression models were used to assess predictors of 80% MPR.

RESULTS

A total of 5825 patients met the study inclusion criteria. About 70% of patients received manufacturer-provided injection training and 75% were eligible for, and utilized, copayment assistance; 74.3% of patients accessing sponsor provided support achieved a desired MPR of greater than or equal to 80%. Patients were 40% more likely to reach goal if injection training was provided by the manufacturer (OR = 1.435; 95% CI = 1.258-1.636) and were 30.6% more likely to achieve goal when eligible patients utilized copayment assistance programs (OR = 1.306; 95% CI = 1.109-1.570). Patients reinitiating treatment were at risk of lower adherence rates (OR = 0.605; CI = 0.476-0.769) compared to those who were new to therapy.

CONCLUSIONS

Manufacturer-provided patient support programs improve adherence to glatiramer acetate therapy.

Comparison of adherence and persistence among multiple sclerosis patients treated with disease-modifying therapies: a retrospective administrative claims analysis

PURPOSE

To compare adherence and persistence among patients with multiple sclerosis (MS) initiated on disease-modifying therapy (DMTs), including intramuscular (IM) interferon beta-1a (IFNβ-1a), subcutaneous (SC) IFNβ-1a, IFNβ-1b, or glatiramer acetate (GA).

METHODS

MS patients initiated on IM-IFNβ-1a, SC-IFNβ-1a, IFNβ-1b, or GA between January 1, 2000 and January 2, 2008 were identified from a retrospective claims database study associated with a large US health plan. The date of DMT initiation was the index date; patients were observed for 6 months before and 12-36 months after the index date. Adherence to the index DMT was measured with a medication possession ratio (MPR), the proportion of days patients possessed their index DMTs; MPR ≥ 0.80 was considered adherent. Persistence was time in days from index date until the earlier of a minimum 60-day gap in DMT therapy or the last DMT claim during follow-up. Adherence and persistence were modeled with logistic and Cox proportional hazard regressions, respectively.

RESULTS

The study population comprised 6,680 patients in the DMT cohorts: IM-IFNβ-1a (N = 2,305, 34.5%); IFNβ-1b (N = 894, 13.4%); GA (N = 2,270, 34.0%); and SC-IFNβ-1a (N = 1,211, 18.1%). The IM-IFNβ-1a cohort had significantly higher regression-adjusted odds of adherence relative to the other cohorts: 52.4% higher odds versus the IFNβ-1b cohort (OR = 0.656, CI = 0.561-0.768); 33.5% higher odds versus the GA cohort (OR = 0.749, CI = 0.665-0.844); and 20.6% higher odds versus the SC-IFNβ-1a cohort (OR = 0.829, CI = 0.719-0.957). There were no consistent differences in persistence between the cohorts.

CONCLUSION

IM-IFNβ-1a patients had significantly higher odds of adherence compared with other DMT cohorts, possibly attributable to IM-IFNβ-1a's less frequent dosing schedule. The benefits of adherence may include better quality of life, lower risk of relapse, and fewer hospitalizations and emergency visits, making adherence a critical component of MS management.
