The Effect of Therapeutic Alliance on Attitudes Toward Psychiatric Medications in Schizophrenia

Rates and correlates of medication non-adherence behaviors and attitudes in adult patients with early psychosis

PURPOSE

Literature on antipsychotic medication adherence in early psychosis primarily assessed adherence behaviors and focused on young patients. There is a paucity of research investigating negative medication attitude and its determinants in the early illness course, particularly in older-aged sample. We aimed to examine prevalence and correlates of medication non-adherence behaviors and negative medication attitudes separately in adult patients with early psychosis.

METHODS

One hundred ninety-nine Chinese early psychosis patients aged 26-55 years who had received three-year treatment for first psychotic episode in Hong Kong were examined. Assessments encompassing socio-demographics, premorbid adjustment, clinical and treatment profiles, self-stigma and therapeutic alliance were conducted. Patients were evaluated with Medication Compliance Questionnaire, which is a modified Chinese-translated version of Medication Adherence Rating Scale and includes items measuring adherence behaviors and attitudes towards medications.

RESULTS

Rates of medication non-adherence and negative attitude towards medications were 38.7% and 50.8%, respectively. Multivariate regression analysis showed that more severe positive symptoms, greater self-stigma and negative medication attitude were independently associated with medication non-adherence. Negative attitude towards medications was significantly associated with younger age, higher educational attainment, diagnosis of other psychotic disorders, poorer insight, greater self-stigma and less satisfaction with communication with healthcare staff, which represented an index reflecting suboptimal therapeutic alliance.

CONCLUSION

Antipsychotic non-adherence and negative medication attitudes are frequently observed in adult early psychosis patients. Our findings indicate that poor insight, elevated self-stigma and suboptimal therapeutic alliance may constitute potential treatment targets for promoting medication adherence and rectifying negative medication attitudes in the early illness stage.

A realist review of medication optimisation of community dwelling service users with serious mental illness

BACKGROUND

Severe mental illness (SMI) incorporates schizophrenia, bipolar disorder, non-organic psychosis, personality disorder or any other severe and enduring mental health illness. Medication, particularly antipsychotics and mood stabilisers are the main treatment options. Medication optimisation is a hallmark of medication safety, characterised by the use of collaborative, person-centred approaches. There is very little published research describing medication optimisation with people living with SMI.

OBJECTIVE

Published literature and two stakeholder groups were employed to answer: What works for whom and in what circumstances to optimise medication use with people living with SMI in the community?

METHODS

A five-stage realist review was co-conducted with a lived experience group of individuals living with SMI and a practitioner group caring for individuals with SMI. An initial programme theory was developed. A formal literature search was conducted across eight bibliographic databases, and literature were screened for relevance to programme theory refinement. In total 60 papers contributed to the review. 42 papers were from the original database search with 18 papers identified from additional database searches and citation searches conducted based on stakeholder recommendations.

RESULTS

Our programme theory represents a continuum from a service user's initial diagnosis of SMI to therapeutic alliance development with practitioners, followed by mutual exchange of information, shared decision-making and medication optimisation. Accompanying the programme theory are 11 context-mechanism-outcome configurations that propose evidence-informed contextual factors and mechanisms that either facilitate or impede medication optimisation. Two mid-range theories highlighted in this review are supported decision-making and trust formation.

CONCLUSIONS

Supported decision-making and trust are foundational to overcoming stigma and establishing 'safety' and comfort between service users and practitioners. Avenues for future research include the influence of stigma and equity across cultural and ethnic groups with individuals with SMI; and use of trained supports, such as peer support workers.

Personal and Social Functioning and Health-Related Quality of Life in Patients with Schizophrenia Treated with the Long-Acting Injectable Antipsychotic Risperidone ISM

OBJECTIVE

To analyze the effect of Risperidone ISM on social functioning and health-related quality of life (HR-QoL) in both short- and long-term treatment of patients with schizophrenia.

PATIENTS AND METHODS

This analysis was based on data from both phases of the PRISMA-3 study, including 433 relapsed patients from the double-blind (DB) phase of the PRISMA-3 trial who were treated for 12-weeks with once-monthly (every 28 days) intramuscular Risperidone ISM 75 mg or 100 mg (n = 288), or placebo (n = 145), as well as 174 patients transitioning from the DB to an open-label 52-week extension (OLE) phase, plus 41 de novo patients treated on a stable maintenance dose of oral risperidone. The clinician-administered Personal and Social Performance (PSP) scale and the patient-reported 20-item Subjective Well-being under Neuroleptics scale (SWN-20) were used to measure social functioning and HR-QoL outcomes, respectively.

RESULTS

Risperidone ISM significantly improved PSP total score from baseline to endpoint (Day 85) versus placebo in the DB phase with mean change total score (95% CI) of 10.7 (9; 12) compared to 4.8 (3; 7) for placebo (p < 0.0001). The statistically significant improvement was present from the first measurement time point (Day 29). SWN-20-measured HR-QoL increased on average in patients treated with Risperidone ISM in the DB phase. A significant improvement was also observed for PSP and SWN-20 scores from the OLE baseline to week 52 for patients transitioning from the DB phase. Stable de novo patients maintained similar PSP and SWN-20 scores during the whole OLE phase.

CONCLUSION

Risperidone ISM provided a rapid and sustained improvement in personal and social functioning, and HR-QOL without need of oral risperidone supplementation or loading doses. These findings, along with a fast onset of efficacy, could contribute to reinforcing the therapeutic alliance and possibly an earlier discharge. Moreover, patient functioning continued improving or was maintained with long-term treatment.

Patient Outcomes of Flexible Assertive Community Treatment Compared With Assertive Community Treatment

OBJECTIVE

In many European countries, flexible assertive community treatment (FACT) has replaced assertive community treatment (ACT) despite limited evidence for FACT's effectiveness in improving functional and patient-reported outcomes. This study evaluated the effectiveness of FACT relative to ACT in improving functioning, client satisfaction, and the working alliance.

METHODS

The authors used a nonblinded, quasi-experimental controlled study design to compare outcomes of patients treated by ACT teams that were reconfigured to FACT teams with those of patients treated by a remaining ACT team. Patients from nine ACT teams in the Capital Region of Denmark were included. Six of the nine ACT teams were reconfigured to FACT in 2018 and 2019 by integrating them with community mental health teams. The remaining three ACT teams were used as control groups. Assignment to treatment was based solely on administrative considerations.

RESULTS

The study included 131 patients (FACT, N=74; ACT, N=57). Patients treated by FACT teams had poorer personal and social functioning than patients assigned to ACT teams (adjusted difference in means=-2.9, 95% CI=-5.8 to -0.1). No between-group differences were found in client satisfaction or working alliance.

CONCLUSIONS

Patients treated by FACT teams had significantly lower functioning than patients treated by ACT teams, but the clinical relevance or causality of this finding remains unclear. Given the reconfiguration of the FACT teams during follow-up, along with substantial drop-out rates and baseline differences between the two groups, these results must be interpreted with caution. The findings require further examination in a randomized controlled trial that includes fidelity measures of the treatment models.

Polypharmacy- Purpose, Benefits and Limitations

With what has become increasingly common among nearly all medical specialties, the number of patients who have various comorbid diseases both psychiatrically and mentally challenges the field of psychiatry. As a result, it is not uncommon physicians are imposed with treatment decisions regarding polypharmacy- the use of multiple medications to treat either different diseases, or even many times, the same illness. In recent years the concept of polypharmacy has been known to have a negative undertone, implying its use is inappropriate or causing more harm than potential benefit. Although the use of any medication should involve a risk versus benefit discussion, when used with good clinical judgment and pharmacologically sound knowledge this practice can be potentially life altering for patients.
