What contributes to patient and parent satisfaction with medication in the treatment of children with ADHD? A report on the development of a new rating scale

Patient-reported outcome measures for medication treatment satisfaction: a systematic review of measure development and measurement properties

BACKGROUND

Medication Treatment Satisfaction (M-TS) from the patients' perspective is important for comprehensively evaluating the effect of medicines. The extent to which current patient-reported outcome measures (PROMs) for M-TS are valid, reliable, responsive, and interpretable remains unclear. To assess the measurement properties of existing PROMs for M-TS and to highlight research gaps.

METHODS

Using PubMed, Embase (Ovid), Cochrane library (Ovid), IPA (Ovid), PsycINFO, Patient-Reported Outcome and Quality of Life Questionnaires biomedical databases, and four Chinese databases, we performed a systematic search for studies addressing the development and validation of PROMs for M-TS. Based on the Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) guideline, pairs of reviewers independently assessed the measurement properties of the PROMs and rated the quality of evidence on the measurement properties of each PROM. (The Open Science Framework registration: https://doi.org/10.17605/OSF.IO/8S5ZM ).

RESULTS

This review identified 69 PROMs for M-TS in 114 studies (four generic, 32 disease-specific, and 33 drug-specific) of which 60 were intended for adults. All provided limited or no information regarding interpretability. Most demonstrated appropriate construct validity including convergent validity (39/69) and discriminative or known-groups validity (40/69) (high to moderate quality of evidence). Only a few provided evidence of sufficient content validity (8/69), structural validity (13/69), and internal consistency (11/69). Of 38 PROMs reporting test-retest reliability, results in 24 provided evidence of satisfactory test-retest reliability (18 with high to moderate, 6 with low to very low quality of evidence). Few PROMs reported responsiveness (16/69). Two generic PROMs (Treatment Satisfaction Questionnaire for Medication initial Version 1.4, TSQM-1.4; Treatment Satisfaction with Medicines Questionnaire, SATMED-Q) and one drug-specific PROM (Insulin Treatment Satisfaction Questionnaire, ITSQ) demonstrated both satisfactory validity and reliability.

CONCLUSIONS

Most existing PROMs for M-TS require further exploration of measurement properties. Reporting guidelines are needed to enhance the reporting quality of the development and validation of PROMs for M-TS.

Important aspects of experiences from patients and parents related to medications in Child and Adolescents Mental Health Services (CAMHS) - a qualitative study

PURPOSE

Patient-reported experiences are a key source of information on quality in mental health care. Most patient experience surveys are limited to assessments from adults, including those conducted by parents or proxies on behalf of others. The aim of this study was to produce findings to inform development of modules on patient and parent experiences with medication in outpatient CAMHS in Norway, for use in previously validated instruments applied in national surveys.

PATIENTS AND METHODS

We developed survey questions based on a systematic literature review, expert-group consultations, interviews with adolescents and parents, and pretesting of the modules in a pilot study. This study included adolescents aged 12-17 years and parents with experiences from outpatient CAMHS and we present findings from semi-structured interviews.

RESULTS

Adolescents with ADHD emphasized the following aspects as important concerning medication use in CAMHS: positive effects of medication like better function and concentration in school and change of behaviour. They also stressed the importance of side effects such as eating problems, nausea, loss of appetite, insomnia, and changes in thoughts and feelings. In addition, adolescents highlighted the significance of aspects as support in daily routines for taking medications, while parents highlighted needs for a professional follow-up care. Parents emphasized aspects regarding their children's medication included both positive effects and change in behaviour, as well as their identification of negative side effects.

CONCLUSION

Our findings from semi-structured interviews identified important aspects reported by both patients and parents on functions, side effects and follow-up care related to medication. The results indicated that both groups emphasized corresponding aspects of what was important regarding medication. However, when it came to follow-up care, the two groups highlighted distinct aspects, indicating differing priorities or concerns in this area.

Patient-reported outcome measures for medication-related quality of life: A scoping review

BACKGROUND

Medication use is common for the prevention and treatment of many health conditions. Understanding the impact of medication-taking on quality of life is important, as it could contribute to better care plans and improve shared decision-making between patients and healthcare providers.

OBJECTIVE

To systematically identify and summarize the extent of literature on patient-reported outcome measures (PROMs) for medication-related quality of life (QoL).

METHODS

Medline, Embase, PsycINFO, and Health and Psychosocial Instruments databases were searched until May 17, 2021 for peer-reviewed, original research articles that included a PROM for medication-related QoL and reported its psychometric properties. Study selection were completed by pairs with a third reviewer resolving any conflicts. Data were extracted by the study team using a form in Microsoft Excel. Extracted data were summarized descriptively and tabulated numerically.

RESULTS

We screened 8,878 records, including 170 full-text articles, of which 86 met the criteria for inclusion. We identified 80 unique PROMs. Over half (n = 53) described measuring treatment satisfaction and less than one quarter measured medication related-QoL more broadly. Most of the included PROMs were targeted towards populations with specific health conditions including cancer (n = 9) and diabetes (n = 8), as well as individuals taking medication for non-specific conditions (n = 7). The most reported psychometric properties were internal consistency (n = 75) and construct validity (n = 77). All PROMs but one (n = 79) assessed physical health but fewer assessed other QoL dimensions (e.g., autonomy, interactions with providers).

CONCLUSIONS

We found that the PROMs were designed for condition-specific or medication-specific populations, with few for general medication-related QoL. Future research should focus on assessing medication-related QoL measures for broader populations such as those with disabilities, multimorbidity, or experiencing polypharmacy. There needs to be more guidance on how to implement the use of PROMs in clinical settings, as well as to ensure consistency around terminology related to QoL.

Application of Prescription Reviews for Traditional Chinese Medicine to Improve Medical Disputes and Patient Satisfaction

Objective

Medical disputes and patient satisfaction are related to inappropriate prescribing practices. We aim to investigate the clinical application of prescription reviews for traditional Chinese medicine (TCM).

Method

TCM prescriptions performed prescription reviews in 372 patients from the year 2019 to 2020 were set as the observation group and those from the year 2017 to 2018 without prescription reviews as the control group (n = 341). According to the Criteria for Assessing Prescription Quality in Chinese Hospitals (CAPQCH) items, “Irrational” and “Rational” TCM prescriptions were determined mainly based on the following category: nonstandard prescriptions, inappropriate prescriptions, and hypernormal prescriptions. The incidence of medical disputes and the degree of patient satisfaction were compared between the two groups.

Result

No difference was found in age and gender between the control group and the observation group. The number of irrational TCM prescriptions from the year 2017 to 2020 was 6, 8, 2, and 3, respectively, with the percentage of 3.725%, 4.480%, 1.201%, and 1.446%. The irrational rate in the observation group (1.344%) was significantly lower than that in the control group (4.106%). Specifically, a higher rate of nonstandard prescriptions was revealed in the control group as compared with the observation group. Moreover, a reduced incidence of medical disputes was revealed in the observation group relative to the control group accompanying with the increased degree of patient satisfaction.

Conclusion

Prescription reviews have high application value in the management of Chinese pharmacies, which can improve the rationality of prescriptions, increase patient satisfaction, and reduce medical disputes.

A Brief Replication Study Comparing Stimulants and Non-Stimulants for Attention-Deficit/Hyperactivity Disorder Treatment with a Focus on the Compliance, Efficacy, and Satisfaction

Objectives

The aim of this study was to compare the compliance, efficacy, and satisfaction associated with methylphenidate and atomoxetine for treating attention-deficit/hyperactivity disorder (ADHD).

Methods

The subjects were 44 patients who met the Diagnostic and Statistical Manual of Mental Disorder-5 diagnostic criteria for ADHD and were treated with methylphenidate or atomoxetine. The methylphenidate formulations included immediate release (IR), extended release (ER), and osmotic-controlled release oral delivery system (OROS). Patients and parents reported the average number of days per week the medication was taken. Efficacy was assessed using the ADHD Rating Scale. Satisfaction with medication scale (SAMS)–parent report form and SAMS–self-report form were used to evaluate parents’ and patients’ satisfaction, respectively.

Results

Patients and parents were more satisfied with methylphenidate than with atomoxetine. There were no significant differences in the compliance with and efficacy of methylphenidate and atomoxetine. Compliance with methylphenidate IR and ER was markedly lower than that with OROS methylphenidate or atomoxetine.

Conclusion

Methylphenidate OROS formulation can be considered a suitable option given its high rates of compliance, satisfaction, and efficacy.

German language questionnaires for assessing implementation constructs and outcomes of psychosocial and health-related interventions: a systematic review

Background

Over the past years, implementation science has gained more and more importance in German-speaking countries. Reliable and valid questionnaires are needed for evaluating the implementation of evidence-based practices. On an international level, several initiatives focused on the identification of questionnaires used in English-speaking countries but limited their search processes to mental health and public health settings. Our aim was to identify questionnaires used in German-speaking countries measuring the implementation of interventions in public health and health care settings in general and to assess their psychometric properties.

Methods

We searched five different bibliographic databases (from 1985 to August 2017) and used several other search strategies (e.g., reference lists, forward citation) to obtain our data. We assessed the instruments, which were identified in an independent dual review process, using 12 psychometric rating criteria. Finally, we mapped the instruments’ scales and subscales in regard to the constructs of the Consolidated Framework for Implementation Research (CFIR) and the Implementation Outcome Framework (IOF).

Results

We identified 31 unique instruments available for the assessment of implementation science constructs. Hospitals and other health care settings were the ones most often investigated (23 instruments), while education and childcare settings, workplace settings, and community settings lacked published instruments. Internal consistency, face and content validity, usability, and structural validity were the aspects most often described. However, most studies did not report on test-retest reliability, known-groups validity, predictive criterion validity, or responsiveness. Overall, the majority of studies did not reveal high-quality instruments, especially regarding the psychometric criteria internal consistency, structural validity, and criterion validity. In addition, we seldom detected instruments operationalizing the CFIR domains intervention characteristics, outer setting, and process, and the IOF constructs adoption, fidelity, penetration, and sustainability.

Conclusions

Overall, a sustained and continuous effort is needed to improve the reliability and validity of existing instruments to new ones. Instruments applicable to the assessment of implementation constructs in public health and community settings are urgently needed.

Trial registration

Methylphenidate for attention deficit hyperactivity disorder (ADHD) in children and adolescents - assessment of adverse events in non-randomised studies

BACKGROUND

Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder in childhood. The psychostimulant methylphenidate is the most frequently used medication to treat it. Several studies have investigated the benefits of methylphenidate, showing possible favourable effects on ADHD symptoms, but the true magnitude of the effect is unknown. Concerning adverse events associated with the treatment, our systematic review of randomised clinical trials (RCTs) demonstrated no increase in serious adverse events, but a high proportion of participants suffered a range of non-serious adverse events.

OBJECTIVES

To assess the adverse events associated with methylphenidate treatment for children and adolescents with ADHD in non-randomised studies.

SEARCH METHODS

In January 2016, we searched CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL, 12 other databases and two trials registers. We also checked reference lists and contacted authors and pharmaceutical companies to identify additional studies.

SELECTION CRITERIA

We included non-randomised study designs. These comprised comparative and non-comparative cohort studies, patient-control studies, patient reports/series and cross-sectional studies of methylphenidate administered at any dosage or formulation. We also included methylphenidate groups from RCTs assessing methylphenidate versus other interventions for ADHD as well as data from follow-up periods in RCTs. Participants had to have an ADHD diagnosis (from the 3rd to the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders or the 9th or 10th edition of theInternational Classification of Diseases, with or without comorbid diagnoses. We required that at least 75% of participants had a normal intellectual capacity (intelligence quotient of more than 70 points) and were aged below 20 years. We excluded studies that used another ADHD drug as a co-intervention.

DATA COLLECTION AND ANALYSIS

Fourteen review authors selected studies independently. Two review authors assessed risk of bias independently using the ROBINS-I tool for assessing risk of bias in non-randomised studies of interventions. All review authors extracted data. We defined serious adverse events according to the International Committee of Harmonization as any lethal, life-threatening or life-changing event. We considered all other adverse events to be non-serious adverse events and conducted meta-analyses of data from comparative studies. We calculated meta-analytic estimates of prevalence from non-comparative cohorts studies and synthesised data from patient reports/series qualitatively. We investigated heterogeneity by conducting subgroup analyses, and we also conducted sensitivity analyses.

MAIN RESULTS

We included a total of 260 studies: 7 comparative cohort studies, 6 of which compared 968 patients who were exposed to methylphenidate to 166 controls, and 1 which assessed 1224 patients that were exposed or not exposed to methylphenidate during different time periods; 4 patient-control studies (53,192 exposed to methylphenidate and 19,906 controls); 177 non-comparative cohort studies (2,207,751 participants); 2 cross-sectional studies (96 participants) and 70 patient reports/series (206 participants). Participants' ages ranged from 3 years to 20 years. Risk of bias in the included comparative studies ranged from moderate to critical, with most studies showing critical risk of bias. We evaluated all non-comparative studies at critical risk of bias. The GRADE quality rating of the evidence was very low.Primary outcomesIn the comparative studies, methylphenidate increased the risk ratio (RR) of serious adverse events (RR 1.36, 95% confidence interval (CI) 1.17 to 1.57; 2 studies, 72,005 participants); any psychotic disorder (RR 1.36, 95% CI 1.17 to 1.57; 1 study, 71,771 participants); and arrhythmia (RR 1.61, 95% CI 1.48 to 1.74; 1 study, 1224 participants) compared to no intervention.In the non-comparative cohort studies, the proportion of participants on methylphenidate experiencing any serious adverse event was 1.20% (95% CI 0.70% to 2.00%; 50 studies, 162,422 participants). Withdrawal from methylphenidate due to any serious adverse events occurred in 1.20% (95% CI 0.60% to 2.30%; 7 studies, 1173 participants) and adverse events of unknown severity led to withdrawal in 7.30% of participants (95% CI 5.30% to 10.0%; 22 studies, 3708 participants).Secondary outcomesIn the comparative studies, methylphenidate, compared to no intervention, increased the RR of insomnia and sleep problems (RR 2.58, 95% CI 1.24 to 5.34; 3 studies, 425 participants) and decreased appetite (RR 15.06, 95% CI 2.12 to 106.83; 1 study, 335 participants).With non-comparative cohort studies, the proportion of participants on methylphenidate with any non-serious adverse events was 51.2% (95% CI 41.2% to 61.1%; 49 studies, 13,978 participants). These included difficulty falling asleep, 17.9% (95% CI 14.7% to 21.6%; 82 studies, 11,507 participants); headache, 14.4% (95% CI 11.3% to 18.3%; 90 studies, 13,469 participants); abdominal pain, 10.7% (95% CI 8.60% to 13.3%; 79 studies, 11,750 participants); and decreased appetite, 31.1% (95% CI 26.5% to 36.2%; 84 studies, 11,594 participants). Withdrawal of methylphenidate due to non-serious adverse events occurred in 6.20% (95% CI 4.80% to 7.90%; 37 studies, 7142 participants), and 16.2% were withdrawn for unknown reasons (95% CI 13.0% to 19.9%; 57 studies, 8340 participants).

AUTHORS' CONCLUSIONS

Our findings suggest that methylphenidate may be associated with a number of serious adverse events as well as a large number of non-serious adverse events in children and adolescents, which often lead to withdrawal of methylphenidate. Our certainty in the evidence is very low, and accordingly, it is not possible to accurately estimate the actual risk of adverse events. It might be higher than reported here.Given the possible association between methylphenidate and the adverse events identified, it may be important to identify people who are most susceptible to adverse events. To do this we must undertake large-scale, high-quality RCTs, along with studies aimed at identifying responders and non-responders.

Parent Perceptions of Medication Treatment for Preschool Children with ADHD

This study sought to examine parent perceptions of medication use for 151 preschool children (M _age  = 5.05 years, 78% male, 82% Hispanic/Latino) with or at-risk for ADHD who were medication naive. Parents completed questionnaires regarding family background and perceptions of medication treatment. Parents and teachers completed ratings of child diagnostic symptomatology, behavioral functioning, and functional impairment. Results indicate that only 45% of parents were open to the possibility of medication. No associations were found between child demographics, severity of ADHD symptoms, or level of functional impairment and parental openness to medication. On the other hand, children of parents who were open to medication tended to have higher levels of oppositionality and aggression (as reported by parents but not teachers) compared with children of parents who were not open to medication. These findings are discussed in the context of early intervention given their implications for a variety of treatment providers.

Effect of Comprehensive Therapy based on Chinese Medicine Patterns on Self-Efficacy and Effectiveness Satisfaction in Chronic Obstructive Pulmonary Disease Patients

OBJECTIVE

To evaluate the effect of comprehensive therapy based on Chinese medicine (CM) patterns on self-efficacy and satisfaction with its effectiveness in patients with chronic obstructive pulmonary disease (COPD).

METHODS

A total of 216 patients were randomly divided into the trial group (n =108) and the control group (n=108) based on the stratified and block randomization design. Patients in the trial group were treated with conventional Western medicine combined with Bufei Jianpi Granules (), Bufei Yishen Granules (), and Yiqi Zishen Granules () according to the CM patterns respectively, and patients in the control group were treated with conventional Western medicine. The COPD Self-Efficacy Scale (CSES) and the Effectiveness Satisfaction Questionnaire for COPD (ESQ-COPD) were employed in a 6-month treatment and in further 6 month follow-up visit.

RESULTS

Among the 216 patients, 191 patients (97 in the trial group and 94 in the control group) fully completed the study. After 12-month treatment and follow-up, the mean scores of the trial group all continued to increase over time, which were significantly higher than those of the control group (P <0.05), and the improvement in the following trial group domain: negative affect domain (12.13%), intense emotional arousal domain (12.21%), physical exertion domain (11.72%), weather/environmental domain (13.77%), behavioral risk domain (7.67%) and total score (10.65%). The trial group also exhibited significantly higher mean scores in the ESQ-COPD (P <0.05) and the improvement in the following domain: capacity for life and work domain (30.59%), clinical symptoms domain (53.52%), effect of therapy domain (35.95%), convenience of therapy domain (35.54%), and whole effect domain (52.47%).

CONCLUSIONS

Bufei Jianpi Granules, Bufei Yishen Granules and Yiqi Zishen Granules can improve the self-efficacy and satisfaction of COPD patients.

Caregiver perspective on pediatric attention-deficit/hyperactivity disorder: medication satisfaction and symptom control

The caregiver perspective on pediatric attention-deficit/hyperactivity disorder (ADHD) study (CAPPA) was a web-based, cross-sectional survey of caregivers of children and adolescents (6-17 years of age) with ADHD and was conducted in 10 European countries. CAPPA included caregiver assessments of global medication satisfaction, global symptom control, and satisfaction with ADHD medication attributes. Overall, 2,326 caregiver responses indicated that their child or adolescent was currently receiving ADHD medication and completed the "off medication" assessment required for inclusion in the present analyses. Responses to the single-item global medication satisfaction question indicated that 88% were satisfied (moderately satisfied to very satisfied) with current medication and 18% were "very satisfied" on the single-item question. Responses to the single-item global symptom control question indicated that 47% and 19% of caregivers considered their child or adolescent's symptoms to be "controlled" or "very well controlled", respectively. Significant variations in response to the questions of medication satisfaction and symptom control were observed between countries. The correlation between the global medication satisfaction and global symptom control questions was 0.677 (P<0.001). Global medication satisfaction was significantly correlated (P<0.001) with all assessed medication attributes, with the highest correlations observed for symptom control (r=0.601) and effect duration (r=0.449). Correlations of medication attributes with global symptom control were generally lower than with global medication satisfaction but were all statistically significant (P<0.001). CAPPA medication satisfaction and symptom control were also significantly correlated (P<0.001) with symptom control as based on the ADHD-Rating Scale-IV symptom score and the number of bad days per month when on medication. In conclusion, caregiver responses in this European sample suggest that current treatment could potentially be improved. The observed correlations of global medication satisfaction with global symptom control and other CAPPA assessments, including medication attributes, provide support for the inter-connectivity of the medication satisfaction and symptom control.

Parent-reported symptoms, impairment, helpfulness of treatment, and unmet service needs in a follow-up of outpatient children with attention-deficit/hyperactivity disorder

BACKGROUND

Limited information exists regarding the associations between impairment, symptoms, helpfulness of treatments, and service needs after initial treatment of children with attention-deficit/hyperactivity disorder (ADHD).

AIMS

The aims of this study were to examine persistence rates and associations between parent-reported symptoms, impairment, helpfulness of treatments, and service needs in a retrospective follow-up study of children with ADHD.

METHODS

Parents of 214 children with a mean age of 12.6 years (SD = 2.1) who were diagnosed with ADHD at five child and adolescent mental health clinics (CAMHS) completed questionnaires 1-10 years (mean = 3.7 years, SD = 2.2) after baseline assessment. The response rate was 43.4%. A community comparison group (n = 110) was recruited from the same area.

RESULTS

Approximately two-thirds (60.3%) of the sample fulfilled the DSM-IV symptom criteria of ADHD at follow-up, 84.3% were functionally impaired, and most children (84.7%) were on medication. Inattentive and emotional symptoms were the strongest predictors of impairment across impairment areas. Perceived helpfulness of different treatments varied from 71.8-88.7%, and no significant difference was found between the ADHD sub-groups regarding reported helpfulness. 'Adjustment of the school situation' was the most frequent service need, and approximately half of the parents reported needs for care co-ordination. Children fulfilling the symptom criteria of the ADHD Combined sub-group were most impaired and had most service needs.

CONCLUSIONS

At follow-up, children were highly symptomatic and impaired, despite a high rate of persistent medication treatment. The findings underline the need for more tailored treatment and co-ordinated care over time.

An observational study of once-daily modified-release methylphenidate in ADHD: quality of life, satisfaction with treatment and adherence

Attention deficit hyperactivity disorder (ADHD) impacts significantly on the quality of life (QoL) of patients and their families. Choice of therapy is increasingly influenced by treatment satisfaction and patient preference, with once-daily modified-release methylphenidate (MPH-MR) formulations offering clear benefits compared with immediate-release (IR) dosage forms. The effects of MPH-MR on QoL in ADHD have not been widely investigated and need more clarity in practice. The open-label OBSEER study evaluated the effectiveness and tolerability of Equasym XL(®), a MPH-MR formulation, in routine practice. Children and adolescents (aged 6-17 years) with ADHD and attending school were included if Equasym XL(®) treatment was planned by the treating physician. Physicians, parents and patients completed questionnaires assessing QoL (KINDL; parent, child or adolescent versions), satisfaction with medication, adherence and treatment tolerability at baseline (Visit 1), 1-3 weeks (Visit 2) and 6-12 weeks (Visit 3) over a maximum 3-month observation period. Data from 822 consecutively referred patients were analysed. QoL and medication satisfaction increased from Visit 1 to Visit 3, with both patients and parents rating therapy with Equasym XL(®) as better than previous drug therapy. KINDL total score effect sizes were 0.67 (parents' ratings), 0.52 (children's ratings) and 0.51 (adolescents' ratings; all p < 0.001). All KINDL subscores also increased: both parents and patients had the greatest improvement for school. Adherence to Equasym XL(®) was frequently rated as superior to prior treatment, particularly compared with MPH-IR repeated dosing. Treatment was generally well tolerated; approximately 3% of the patients discontinued treatment due to adverse events. Equasym XL(®) improved QoL compared with prior therapy, and resulted in good medication satisfaction and adherence in drug-naïve and previously treated patients.
