Long-Term Treatment Acceptance: What Is It, and How Can It Be Assessed?

Intramuscular versus enteral penicillin prophylaxis to prevent progression of rheumatic heart disease: Study protocol for a noninferiority randomized trial (the GOALIE trial)

BACKGROUND

Rheumatic Heart Disease (RHD) persists as a major cardiovascular driver of mortality and morbidity among young people in low-and middle-income countries. Secondary antibiotic prophylaxis (SAP) with penicillin remains the cornerstone of RHD control, however, suboptimal treatment adherence undermines most secondary prevention programs. Many of the barriers to optimal SAP adherence are specific to the intramuscular form of penicillin and may potentially be overcome by use of oral penicillin. This noninferiority trial is comparing the efficacy of intramuscular to oral penicillin SAP to prevent progression of mild RHD at 2 years.

METHODS/DESIGN

The Intramuscular vs Enteral Penicillin Prophylaxis to Prevent Progression of Rheumatic Heart Disease (GOALIE) trial is randomizing Ugandan children aged 5 to 17 years identified by echocardiographic screening with mild RHD (Stage A or B as defined by 2023 World Heart Federation criteria) to Benzathine Benzyl Penicillin G (BPG arm, every-28-day intramuscular penicillin) or Phenoxymethyl Penicillin (Pen V arm, twice daily oral penicillin) for a period of 2 years. A blinded echocardiography adjudication panel of 3 RHD experts and 2 cardiologists is determining the echocardiographic stage of RHD at enrollment and will do the same at study completion by consensus review. Treatment adherence and study retention are supported through peer support groups and case management strategies. The primary outcome is the proportion of children in the Pen V arm who progress to more advanced RHD compared to those in the BPG arm. Secondary outcomes are patient-reported outcomes (treatment acceptance, satisfaction, and health related quality of life), costs, and cost-effectiveness of oral compared to intramuscular penicillin prophylaxis for RHD. A total sample size of 1,004 participants will provide 90% power to demonstrate noninferiority using a margin of 4% with allowance for 7% loss to follow-up. Participant enrollment commenced in October 2023 and final participant follow-up is expected in December 2026. The graphical abstract (Fig. 1) summarizes the flow of echocardiographic screening, participant enrollment and follow-up.

DISCUSSION

The GOALIE trial is critical in global efforts to refine a pragmatic approach to secondary prevention for RHD control. GOALIE insists that the inferiority of oral penicillin be proven contemporarily and against the most important near-term clinical outcome of progression of RHD severity. This work also considers other factors that could influence the adoption of oral prophylaxis and change the calculus for acceptable efficacy including patient-reported outcomes and costs.

How glaucoma patients balance between the advantages and disadvantages of acceptance to the recommended treatment regimen in real-life: Perspectives from a middle-income country

PURPOSE

Patients with primary open-angle glaucoma (POAG) are required to take long-term treatments with topical medications to halt disease progression. This cross-sectional survey aimed to describe the level of acceptance of Brazilian patients toward the long-term treatment with eyedrops and to find possible correlates of high acceptance.

METHODS

POAG patients were recruited from the Glaucoma Service-Santa Casa of Sao Paulo, Sao Paulo, Brazil. Clinical and demographic data were retrieved from participants' electronic records. All patients answered the ACCEPT© questionnaire. This is a generic patient-reported outcome questionnaire specifically developed to assess patients' acceptance of long-term medications and not adherence. Summed scores and those for each domain were calculated to range from 0 to 100 with a higher score indicating greater acceptance.

RESULTS

The sample comprised 96 patients with POAG. The mean age was 63.2 ± 8.9 years; 48 were male and 48 female; 55 (57.3%) were white, 36 (37.5%) African-Brazilian, and 5 (5.2%) were of mixed color; most patients (97.9%) had less than high school degree and all had a family income

CONCLUSIONS

In this cohort of Brazilian patients with glaucoma, acceptance of treatment was high. Patients seems to have noticed more benefits than risks to the recommended treatment regimen.

Finalization and Validation of Questionnaire and Algorithm of SPUR, a New Adherence Profiling Tool

Purpose

The SPUR (Social, Psychological, Usage and Rational) Adherence Profiling Tool is a recently developed adaptive instrument for assessing key patient-level drivers for non-adherence. This study describes the SPUR questionnaire's finalization and psychometric evaluation.

Patients and Methods

Data were collected through an online survey among patients with type 2 diabetes included by general practitioners and diabetologists in France. The survey included four questionnaires, SPUR and three validated adherence measures: BMQ, MARS and ACCEPT. Item-level analysis and a partial credit model (PCM) were performed to refine the response option coding of SPUR items. The final item selection of SPUR was defined using a PCM and a principal component analysis (PCA). Construct validity, concurrent validity and known-groups validity were assessed on the final SPUR questionnaire.

Results

A total of 245 patients (55% men, mean age of 63 years) completed the survey remotely and were included in this analysis. Refining response option coding allowed a better discrimination of patients on the latent trait. After item selection, a short, an intermediate, and a long form composed the final SPUR questionnaire. The short form will be used to screen patients for risk and then the other forms will allow the collection of further information to refine the risk assessment and decide the best levers for action. Results obtained were supportive of the construct validity of the forms. Their concurrent validity was demonstrated: moderate to high significant correlations were obtained with BMQ, MARS and ACCEPT scores. Their known-groups validity were shown with a logical pattern of higher scores obtained for patients considered non-adherent and significant differences between the scores obtained for patients considered adherent versus non-adherent.

Conclusion

SPUR is a valid tool to evaluate the risk of non-adherence of patients, allowing effective intervention by providing insights into the respective individual reasons for lack of adherence.

Experience of hospital-initiated medication changes in older people with multimorbidity: a multicentre mixed-methods study embedded in the OPtimising thERapy to prevent Avoidable hospital admissions in Multimorbid older people (OPERAM) trial

BACKGROUND

A patient-centred approach to medicines optimisation is considered essential. The OPtimising thERapy to prevent Avoidable hospital admissions in Multimorbid older people (OPERAM) trial evaluated the effectiveness of medication review with shared decision-making (SDM) in older people with multimorbidity. Beyond evaluating the clinical effectiveness, exploring the patient experience facilitates a better understanding of contextual factors and mechanisms affecting medication review effectiveness.

OBJECTIVE

To explore experiences of hospital-initiated medication changes in older people with multimorbidity.

METHODS

We conducted a multicentre mixed-methods study, embedded in the OPERAM trial, combining semi-structured interviews and the Beliefs about Medicines Questionnaire (BMQ) with a purposive sample of 48 patients (70-94 years) from four European countries. Interviews were analysed using the Framework approach. Trial implementation data on SDM were collected and the 9-item SDM questionnaire was conducted with 17 clinicians.

RESULTS

Patients generally displayed positive attitudes towards medication review, yet emphasised the importance of long-term, trusting relationships such as with their general practitioners for medication review. Many patients reported a lack of information and communication about medication changes and predominantly experienced paternalistic decision-making. Patients' beliefs that 'doctors know best', 'blind trust', having limited opportunities for questions, use of jargon terms by clinicians, 'feeling too ill', dismissive clinicians, etc highlight the powerlessness some patients felt during hospitalisation, all representing barriers to SDM. Conversely, involvement of companions, health literacy, empathetic and trusting patient-doctor relationships, facilitated SDM. Paradoxical to patients' experiential accounts, clinicians reported high levels of SDM. The BMQ showed that most patients had high necessity and low concern beliefs about medicines. Beliefs about medicines, experiencing benefits or harms from medication changes, illness perception, trust and balancing advice between different healthcare professionals all affected acceptance of medication changes.

CONCLUSION

To meet patients' needs, future medicines optimisation interventions should enhance information exchange, better prepare patients and clinicians for partnership in care and foster collaborative medication reviews across care settings.

Relational dynamics involved in therapeutic discordance among prescribers and patients: A Grounded Theory study

OBJECTIVE

No studies have explored the negative process of concordance: discordance in prescribing-medication-taking. This study provides a deeper understanding of discordance as a co-constructed process among patients and prescribers.

METHODS

To explore the question "what psychological and relational processes are involved when therapeutic discordance among prescribers and receivers occurs?" a constructivist Grounded Theory study was carried out through semi-structured interviews with patients and their medical doctors.

RESULTS

The final sample of our study was composed of 29 participants: 16 receivers and 13 prescribers. "Neglecting the relationship", the core category, shapes the therapeutic discordance and connects three main conceptual phases: signing a non-negotiating contract, acting alone, and establishing a superficial relationship.

CONCLUSION

Our grounded theory conceptualization contributes to the concordance-related debate by evidencing the processes among prescribers and receivers in interwoven actions. It offers another dimension to how notions of compliance, adherence and concordance have been theorized to date.

PRACTICE IMPLICATIONS

More than one interaction with receivers is recommended. If there are hints that conflict potentially is compromising the relationship, prescribers should involve intermediaries. Setting aside for a moment, evidence-based justification for treatments and trying to understand prescribers' motivations may boost a positive change.

Patient-Reported Outcomes Through 1 Year of an HIV-1 Clinical Trial Evaluating Long-Acting Cabotegravir and Rilpivirine Administered Every 4 or 8 Weeks (ATLAS-2M)

BACKGROUND

Advances in HIV-1 therapeutics have led to the development of a range of daily oral treatment regimens, which share similar high efficacy rates. Consequently, more emphasis is being placed upon the individual's experience of treatment and impact on quality of life. The first long-acting injectable antiretroviral therapy for HIV-1 (long-acting cabotegravir + rilpivirine [CAB + RPV LA]) may address challenges associated with oral treatment for HIV-1, such as stigma, pill burden/fatigue, drug-food interactions, and adherence. Patient-reported outcomes (PROs) collected in an HIV-1 clinical trial (ATLAS-2M; NCT03299049) comparing participants' experience with two dosing regimens (every 4 weeks [Q4W] vs. every 8 weeks [Q8W]) of CAB + RPV LA are presented herein.

METHODS

PRO endpoints evaluated through 48 weeks of therapy included treatment satisfaction (HIV Treatment Satisfaction Questionnaire [HIVTSQ]), treatment acceptance ("General Acceptance" domain of the Chronic Treatment Acceptance [ACCEPT^®] questionnaire), acceptability of injections (Perception of Injection [PIN] questionnaire), treatment preference (questionnaire), and reasons for switching to/continuing long-acting therapy (exploratory endpoint; questionnaire). Participants were randomized 1:1 to receive CAB + RPV LA Q8W or Q4W. Results were stratified by prior CAB + RPV exposure in either preplanned or post hoc analyses.

RESULTS

Overall, 1045 participants were randomized to the Q8W (n = 522) and Q4W (n = 523) regimens; 37% (n = 391/1045) had previously received CAB + RPV in ATLAS. For participants without prior CAB + RPV exposure, large increases from baseline were reported in treatment satisfaction in both long-acting arms (HIVTSQ status version), with Q8W dosing statistically significantly favored at Weeks 24 (p = 0.036) and 48 (p = 0.004). Additionally, improvements from baseline were also observed in the "General Acceptance" domain of the ACCEPT questionnaire in both long-acting arms for participants without prior CAB + RPV exposure; however, no statistically significant difference was observed between arms at either timepoint (Week 24, p = 0.379; Week 48, p = 0.525). Significant improvements (p < 0.001) in the "Acceptance of Injection Site Reactions" domain of the PIN questionnaire were observed from Week 8 to Weeks 24 and 48 in both arms for participants without prior CAB + RPV exposure. Participants with prior CAB + RPV exposure reported high treatment satisfaction (mean [HIVTSQ status version]: Q8W 62.2/66.0; Q4W 62.0/66.0), treatment acceptance (mean: Q8W 89.3/100; Q4W 91.2/100), and acceptance of injection site reactions (mean [5 = not at all acceptable; 1 = totally acceptable]: Q8W 1.72; Q4W 1.59) at baseline/Week 8 that were maintained over time. Participants without prior CAB + RPV exposure who received Q8W dosing preferred this regimen over oral CAB + RPV (98%, n = 300/306). Among those with prior Q4W exposure, 94% (n = 179/191) preferred Q8W dosing versus Q4W dosing (3%, n = 6/191) or oral CAB + RPV (2%, n = 4/191).

CONCLUSIONS

Both long-acting regimens provided high treatment satisfaction and acceptance, irrespective of prior CAB + RPV exposure, with most participants preferring Q8W dosing over both the Q4W regimen and their previous daily oral regimen. The PRO data collected at Week 48 support the therapeutic potential of CAB + RPV LA.

Patient-Reported Outcomes in ATLAS and FLAIR Participants on Long-Acting Regimens of Cabotegravir and Rilpivirine Over 48 Weeks

The phase 3 ATLAS and FLAIR studies demonstrated that maintenance with Long-Acting (LA) intramuscular cabotegravir and rilpivirine is non-inferior in efficacy to current antiretroviral (CAR) oral therapy. Both studies utilized Patient-Reported Outcome instruments to measure treatment satisfaction (HIVTSQ) and acceptance (ACCEPT general domain), health status (SF-12), injection tolerability/acceptance (PIN), and treatment preference. In pooled analyses, LA-treated patients (n = 591) demonstrated greater mean improvements from baseline than the CAR group (n = 591) in treatment satisfaction (Week 44, + 3.9 vs. +0.5 HIVTSQs-points; p < 0.001) and acceptance (Week 48, +8.8 vs. +2.0 ACCEPT-points; p < 0.001). The acceptability of injection site reactions (PIN) significantly improved from week 5 (2.10 points) to week 48 (1.62 points; p < 0.001). In both studies, ≥ 97% of LA group participants with recorded data preferred LA treatment compared with prior oral therapy. These results further support the potential of a monthly injectable option for people living with HIV seeking an alternative to daily oral treatment.

Adherence to and Acceptance of Once-Daily Tacrolimus After Kidney and Liver Transplant: Results From OSIRIS, a French Observational Study

BACKGROUND

Adherence to immunosuppressive treatments is a major concern in transplanted patients.

METHODS

This 6-month French observational, longitudinal, prospective study aimed to assess patient adherence to and acceptance of once-daily tacrolimus (Advagraf) initiation in kidney and liver transplant recipients. Data from 1106 patients initiating once-daily tacrolimus during posttransplant follow-up were analyzed. Adherence and acceptance were assessed using self-administered questionnaires at inclusion and at 3 and 6 months.

RESULTS

Mean age was 52.4 ± 13.2 years, 61.5% were men. For 94.9% of patients, once-daily tacrolimus was prescribed after switching from twice-daily tacrolimus. At inclusion, 20.9% of patients reported good treatment adherence, 72.0% minor nonadherence, and 7.1% were nonadherent. Mean general acceptance score (range, 0-100) was 77.7 (±24.7). At 3 months, adherence was improved in 21.1%, unchanged in 69.2%, and worsened in 9.7% of patients. Mean general acceptance score was 75.4 (±26.5). General acceptance score was improved in 28.0%, unchanged in 39.4%, and worsened in 32.7% of patients. At 6 months, similar changes in adherence and acceptance were observed. Higher general acceptance score at month 3 was significantly associated with better adherence at month 6.

CONCLUSIONS

Conversion to once-daily tacrolimus led to an improved rate of adherence at month 3 in more than 20% of patients and a worsened rate of adherence in less than 10% of patients.

Assessing patients' acceptance of their medication to reveal unmet needs: results from a large multi-diseases study using a patient online community

Background

Patients with chronic conditions are required to take long-term treatments for their disease itself or to prevent any potential health risks. Measuring patient acceptance of their medication should help to better understand and predict patients’ behavior toward treatment. This study aimed to describe the level of patient acceptance toward various long-term treatments in real life using an online patient community.

Methods

This was an observational, cross-sectional study conducted through the French Carenity platform. All Carenity patient members were invited to complete an online questionnaire including the 25-item ACCEptance by the Patients of their Treatment (ACCEPT©) questionnaire. ACCEPT© measures patient acceptance toward their medication and includes one general acceptance dimension (Acceptance/General) and six treatment-attribute specific dimensions (scores 0–100; lowest to highest acceptance): Acceptance/Medication Inconvenience, Acceptance/Long-term Treatment, Acceptance/Regimen Constraints, Acceptance/Side effects, Acceptance/Effectiveness, and Acceptance/Numerous Medications. Patients included in the analysis were treated adults experiencing any chronic diseases and who responded to at least one ACCEPT© item.

Results

Among the 4193 patients included in the analysis, more than 270 chronic diseases were represented, amidst which 19 included more than 30 patients. Mean ACCEPT© Acceptance/General score for those 19 diseases were 61.2 (SD = 31.9) for type 1 diabetes, 59.8 (SD = 32.3) for asthma, 56.3 (SD = 34.3) for hypertension, 52.0 (SD = 32.2) for chronic obstructive pulmonary disease, 51.7 (SD = 27.0) for epilepsy, 50.1 (SD = 33.1) for bipolar disorder, 49.9 (SD = 33.1) for type 2 diabetes, 48.6 (SD = 31.6) for multiple sclerosis, 46.1 (SD = 34.5) for Crohn’s disease/ulcerative colitis, 44.3 (SD = 31.5) for depression, 42.8 (SD = 31.5) for lupus, 42.3 (SD = 33.0) for arthrosis, 41.8 (SD = 32.6) for Parkinson’s disease, 40.5 (SD = 32.2) for rheumatoid arthritis, 38.6 (SD = 31.7) for breast cancer, 36.4 (SD = 36.4) for myocardial infarction, 35.8 (SD = 32.0) for ankylosing spondylitis, 34.1 (SD = 32.3) for psoriasis, and 33.7 (SD = 31.7) for fibromyalgia.

Conclusions

This first of its kind study enabled ACCEPT© data to be collected in real life for a variety of chronic diseases. These data may help in evaluating and interpreting levels of acceptance in future studies and provide valuable insights about patient priorities and current unmet needs.

Item Reduction, Scoring, and First Validation of the ACCEPTance by the Patients of their Treatment (ACCEPT©) Questionnaire

OBJECTIVES

The objectives of this study were to finalize, develop the scoring, and explore the psychometric properties of the ACCEPTance by the Patients of their Treatment (ACCEPT©) questionnaire, as well as to provide the first elements for its interpretation and guidance for its future use.

METHODS

ACCEPT© was finalized according to reference methods including testing in a pilot study, i.e., a multi-center, observational, longitudinal study conducted in France, in collaboration with a network of pharmacists. Principal component analysis using Varimax rotation was performed. The loadings of items on components in the principal component analysis were used to inform item selection. Validity of the measurement model of ACCEPT© was confirmed using Multi-trait/Multi-item Analysis based on item-scale Spearman correlations. Internal consistency reliability of the questionnaire was assessed by determining the Cronbach's α coefficient. Linear and logistic regressions were used to identify predictors of general acceptance, and to study predictors of persistence.

RESULTS

A total of 189 patients were included. The final version of ACCEPT© is composed of 25 items, distributed in seven dimensions providing a comprehensive appraisal of acceptance of long-term medication, with six scores measuring acceptance of treatment specific attributes and one score measuring general treatment acceptance. The measurement properties of ACCEPT© were overall fairly satisfactory. Regressions showed that Acceptance/Effectiveness is a predictor of general acceptance. However, no predictor of persistence could be identified.

CONCLUSION

The self-administered ACCEPT© questionnaire is a valid and reliable instrument for the assessment of patients' acceptance of long-term medication. Disease-specific and large prospective studies are needed to assess the ability of ACCEPT

Development and Content Validity Testing of a Patient-Reported Treatment Acceptance Measure for Use in Patients Receiving Treatment via Subcutaneous Injection

BACKGROUND

New therapies in development for lowering low-density lipoprotein cholesterol, such as alirocumab, require administration by subcutaneous injections. There is a need to assess the acceptance of such treatments and their mode of administration.

OBJECTIVES

To develop a novel patient-reported outcome measure, the Injection-Treatment Acceptance Questionnaire (I-TAQ), and assess its content validity using qualitative methods.

METHODS

Concepts generated from a literature and instrument review informed the initial drafting of 17 items in the I-TAQ, with item wording adapted from three existing instruments. Three rounds of qualitative interviews were conducted with 29 US-English speaking patients at high cardiovascular risk. Concept elicitation questioning was used to explore patients' treatment experiences followed by cognitive debriefing of the I-TAQ using "think-aloud" methods. Verbatim transcripts were analyzed using thematic analysis.

RESULTS

Qualitative analysis of concept elicitation data identified the following relevant concepts: perceived efficacy, side effects, self-efficacy, convenience, and overall acceptance. Seven (24%) patients discussed an initial fear of needles, but described this as subsiding with no impact on adherence. Five items were added after round one interviews, three of which were retained after round two testing in which two further items were added, forming the conceptually comprehensive 22-item I-TAQ. Patients demonstrated good understanding of item wording, instructions, response scales, and recall period.

CONCLUSIONS

Successive rounds of in-depth interviews resulted in a treatment acceptance measure with strong content validity. Pending demonstration of its psychometric properties, the I-TAQ may prove to be a valuable measure of patients' perspectives toward being treated with low-density lipoprotein cholesterol-lowering therapies requiring subcutaneous injections.

Determinants for acceptance of preventive treatment against heart disease - a web-based population survey

BACKGROUND

Patients' perception of risk and their lifestyle choices are of major importance in the treatment of common chronic diseases. This study reveals determinants for and knowledge about why people accept or reject preventive medical interventions against heart disease.

METHODS

A representative sample of 40-60-year-old Danish inhabitants was invited to participate in a web-based survey. The respondents were presented with a hypothetical scenario and asked to imagine that they were at an increased risk of heart disease, and subsequently presented with an offer of a preventive medical intervention. The aim was to elicit preference structures when potential patients are presented with different treatment conditions.

RESULTS

About one third of the respondents were willing to accept preventive medical treatment. Respondents with personal experience with heart disease were more likely to accept treatment than respondents with family members with heart disease or no prior experience with heart disease. The willingness to accept treatment was similar for both genders, and when adjusting for experience with heart disease, age was not associated with willingness to accept treatment. Socioeconomic status in terms of lower education was positively associated with acceptance. The price of treatment reduced willingness to accept for the lower income groups, whereas it had no effect in the highest income group. Some 57% of respondents who were willing to accept treatment changed their decision following information on potential side effects.

CONCLUSIONS

In accordance with our pre-study hypothesis, individuals with low income were more sensitive to price than individuals with high income. Thus, if the price of preventive medication increases above certain limits, a substantial proportion of the population may refrain from treatment. More than half of the respondents who were initially willing to accept treatment changed their decision when informed about the presence of potential side effects. This is an important observation in relation to risk communication, since most side effects occur very seldom, and a skewed assessment of treatment efficacy compared to risk of side effects may refrain some patients from treatment. Thus, more research is needed to better allow patients to compare treatment efficacy with risk of side effects in quantitative terms.
