Factors influencing the adherence of antipsychotic medication (Aripiprazole) in first-episode psychosis: findings from a grounded theory study

An Adaptable Framework for Factors Contributing to Medication Adherence: Results from a Systematic Review of 102 Conceptual Frameworks

OBJECTIVE

To summarize the available conceptual models for factors contributing to medication adherence based on the World Health Organization (WHO)'s five dimensions of medication adherence via a systematic review, identify the patient groups described in available conceptual models, and present an adaptable conceptual model that describes the factors contributing to medication adherence in the identified patient groups.

METHODS

We searched PubMed®, Embase®, CINAHL®, and PsycINFO® for English language articles published from inception until 31 March 2020. Full-text original publications in English that presented theoretical or conceptual models for factors contributing to medication adherence were included. Studies that presented statistical models were excluded. Two authors independently extracted the data.

RESULTS

We identified 102 conceptual models, and classified the factors contributing to medication adherence using the WHO's five dimensions of medication adherence, namely patient-related, medication-related, condition-related, healthcare system/healthcare provider-related, and socioeconomic factors. Eight patient groups were identified based on age and disease condition. The most universally addressed factors were patient-related factors. Medication-related, condition-related, healthcare system-related, and socioeconomic factors were represented to various extents depending on the patient group. By systematically examining how the WHO's five dimensions of medication adherence were applied differently across the eight different patient groups, we present a conceptual model that can be adapted to summarize the common factors contributing to medication adherence in different patient groups.

CONCLUSION

Our conceptual models can be utilized as a guide for clinicians and researchers in identifying the facilitators and barriers to medication adherence and developing future interventions to improve medication adherence.

Sources of Distress in First-Episode Psychosis: A Systematic Review and Qualitative Metasynthesis

In this study, we aim to increase our understanding of the self-reported sources of distress among people who have experienced first-episode psychosis. Following a systematic literature search, 33 relevant studies containing first-person accounts of first-episode psychosis were identified, which were synthesized using thematic analysis. Two interrelated superordinate themes were identified: intrapersonal distress and interpersonal distress. Participants reported multiple, diverse, and multifaceted sources of distress across both themes. These were substantially different from those routinely recognized and targeted in clinical practice. This review suggests that practitioners who maintain a stance of genuine curiosity about the potential sources of distress for this population will be perceived as more helpful. The findings also highlight the importance of being service user-led when planning and delivering mental health care. Additional clinical and research implications are discussed.

Qualitative systematic review of barriers and facilitators to patient-involved antipsychotic prescribing

BACKGROUND

Despite policy and practice mandates for patient involvement, people with serious mental illness often feel marginalised in decisions about antipsychotic medication. Aims To examine stakeholder perspectives of barriers and facilitators to involving people with serious mental illness in antipsychotic prescribing decisions.

METHOD

Systematic thematic synthesis.

RESULTS

Synthesis of 29 studies identified the following key influences on involvement: patient's capability, desire and expectation for involvement, organisational context, and the consultation setting and processes.

CONCLUSIONS

Optimal patient involvement in antipsychotic decisions demands that individual and contextual barriers are addressed. There was divergence in perceived barriers to involvement identified by patients and prescribers. For example, patients felt that lack of time in consultations was a barrier to involvement, something seldom raised by prescribers, who identified organisational barriers. Patients must understand their rights to involvement and the value of their expertise. Organisational initiatives should mandate prescriber responsibility to overcome barriers to involvement. Declaration of interest None.

The Common Elements of treatment engagement for clinically high-risk youth and youth with first-episode psychosis

AIM

Without treatment, clinically high-risk (CHR) youth or youth with first-episode psychosis (FEP) have increased risk for significant complications from their illness; yet, treatment engagement among these youth is critically low. The purpose of this study was to examine engagement efforts with CHR/FEP youth to stimulate new ideas that might facilitate participation in services for this population.

METHODS

A literature review using distillation methods identified engagement practices reported in two bodies of literature. The first body of literature (i.e. 'CHR/FEP engagement') included 13 studies employing qualitative designs to explore consumer perspectives about treatment engagement practices in samples of CHR/FEP youth and their families. The second body of research (i.e. 'CHR/FEP RCTs') included 18 randomized controlled trials (RCTs) testing treatments for CHR/FEP youth and their families. Engagement practice frequencies were compared with the frequency of these practices within effective engagement interventions, as tested in 40 RCTs within the broader child and adolescent mental health literature (i.e. 'CAMH engagement').

RESULTS

Treatment attrition and attendance were the most frequent engagement outcomes measured in the CHR/FEP RCTs. There were notable efforts described in the CHR/FEP RCTs towards engaging youth and families, yet CHR/FEP RCTs reportedly included only a small proportion of engagement practices described in either the CHR/FEP or CAMH engagement literatures.

CONCLUSION

Results suggest there might be practices available to complement current efforts at engaging CHR/FEP youth in treatment, and that increased attention to the measurement of engagement outcomes could provide important information regarding engagement in a population with low treatment engagement rates.

Factors Affecting Medication Adherence Among Adults with Schizophrenia: A Literature Review

This review aimed to summarize empirical evidence concerning factors relating to medication adherence among patients with schizophrenia. A comprehensive search was implemented to recruit articles which met the present eligibility criteria. Twenty-five articles were included whereby only one was a qualitative study. Greater awareness of illness (insight), previous history of medication adherence, positive attitude toward medication, types of atypical antipsychotics, less severe psychotic symptoms, and social support were identified as factors of medication adherence. Knowledge gaps and methodological limitations were also identified. Implications to clinical practice include providing psychoeducation to patients by increasing their knowledge about illness and medication.

Risk factors for antipsychotic medication non-adherence behaviors and attitudes in adult-onset psychosis

BACKGROUND

Research on antipsychotic medication non-adherence in first-episode psychosis patients tends to examine non-adherence behaviors and attitudes together. Nonetheless, attitudes do not always directly translate into behaviors. We examined the baseline predictors for antipsychotics non-adherence behaviors and attitudes separately in a first-episode psychosis cohort. We also included cognitive impairments as one of the predictor variables as this domain is rarely explored in adherence studies.

METHOD

Participants were 313 adult-onset psychosis patients recruited from the Jockey Club Early Psychosis project in Hong Kong. Demographic, premorbid, clinical, and cognitive characteristics were first assessed at baseline. Six months later, participants completed a 14-item Medication Compliance Questionnaire, which was a modified and Cantonese-translated version of the Medication Adherence Rating Scale that includes items pertaining to both adherence behaviors and attitudes.

RESULTS

Rates of poor adherence behaviors and negative adherence attitudes were 17.6% and 27.8%, respectively. Determinants of poor adherence behavior included more severe positive symptoms, hospitalization at onset of illness, and poorer engagement in extended social network. As for negative adherence attitude, determinants included more severe general psychopathology, poorer insight, more psychic medication side-effects, and poorer performance on backward digit span test and WAIS-R information test.

CONCLUSIONS

The risk factors for non-adherence behaviors and attitudes are different and they should all be taken into careful consideration while formulating appropriate intervention programs to tackle the adherence problem in adult onset psychosis.

A cross-sectional observational study of healthcare professional views of factors affecting teenage adherence with antipsychotic medication

Delays in effective treatment of a first episode psychosis can result in more severe symptoms, a longer time to achieve symptom control and a poorer quality of life; yet around 40% do not take antipsychotic medication as prescribed. There is evidence that patients and staff have different perceptions of what affects adherence with medication. Research in adults suggests healthcare professionals and patients understand the importance of good insight in promoting adherence with medication for schizophrenia; however, healthcare staff may overestimate the impact of side effects and underestimate the importance of medication effectiveness. There is also some evidence to suggest that motivations to take prescribed medication may differ in first and multi-episode psychosis. This research therefore sought views of staff working with adolescents diagnosed with first episode psychosis about what factors affected adherence with antipsychotic medication. Staff responding to the survey felt that young people were more likely to take medication if they felt it would make them better, prevent relapse and if they had a positive rapport with staff. As in an adult population, side effects, particularly weight gain, sedation and muscular side effects, were expressed as a common reason for poor adherence. Doctors and nurses assigned differing importance to parameters such as family views of medication, fear of admission and a preference for cannabis over medication suggesting that views may differ between professional groups Views of young people will be obtained in the next phase of the research study to enable comparison with staff views and consideration of staff interventions to better promote medication adherence. Antipsychotic medication is an effective treatment for first episode psychosis; yet 40% of patients do not take medication as prescribed. Previous research in adults with schizophrenia comparing healthcare professional and patient views suggests that while healthcare professionals recognize the importance of insight in promoting medication adherence, they underestimate the importance of medication efficacy and overestimate the impact of side effects. It was hypothesized that staff in this study would also recognize the importance of insight and positive medication attitudes in teenagers with psychosis, but overestimate the impact of side effects on medication adherence. This cross-sectional observational study sought staff views about factors affecting antipsychotic medication adherence in those aged between 14 and 18 years. An online survey was distributed and 60 responses were subsequently returned. Staff felt that good medication insight as well as positive relationships with staff were important determinants of good medication adherence. The most important influences of poor adherence were poor insight, side effects of medication and a wish to exert personal control around medication decisions. The results therefore confirmed the initial hypothesis. Published literature also provides support for some, but not all, of the staff views expressed in survey responses.

Treatment motivation of men with ED: what motivates men with ED to seek professional help and how can women support their partners?

Although ED can impair sexual satisfaction as well as the quality of partnership and life, men affected often avoid seeking treatment. There is growing evidence that women have an influence on their partner's help-seeking behavior. This qualitative study examined men with ED and their female partners in order to detect motivational factors for men to seek treatment and motivational actions of the women to support their partners. Twelve couples took part in a semi-structured telephone interview, which was performed separately in men and women. Analysis was on the basis of the Grounded Theory. The identified motivational factors could be divided into extrinsic (for example, media, female partner) and intrinsic (for example, desire to clarify the cause of the ED, hope for improvement) factors. Women can support their partners in treatment-seeking through various motivational actions such as talking with each other, showing interest and dealing actively with the problem, appealing to the male self-esteem, supporting the doctor's visit, forcing the treatment, active cooperation and participation in the treatment or initiating sexual intercourse. On the basis of these findings, recommendations for women were developed to support their partners and increase the probability of help-seeking behavior.
