A thematic analysis assessing clinical decision-making in antipsychotic prescribing for schizophrenia

Efficacy and Safety Profiles of Antipsychotic Drugs as Viewed by Psychiatrists: A Comparative Analysis of Cariprazine and Risperidone

BACKGROUND

Physicians hold the belief that the treatment outcomes and the treatment strategy they eventually adopt is largely determined by the differences in medications. Despite numerous studies focusing on the decision-making processes of psychiatrists, including the choice of antipsychotics when prescribing pharmacotherapy, the impact of therapeutic drug profiling on physicians' decision-making remains poorly comprehended.

AIM

The aim of this study is to assess the quantitative differences in perceptions of antipsychotics by psychiatrists using cariprazine and risperidone as examples.

METHODS

A total of 79 psychiatrists were interviewed anonymously in St. Petersburg, Russia. The physicians documented the clinical advantages they perceived drugs to possess relative to one another, following a predetermined principle: A B, A=B, A B (2-AC protocol). The comparison is based on eleven parameters that assess the effectiveness and safety of cariprazine or risperidone. It has been hypothesized that the pattern of responses (qualitative difference) and the degree of preference for each drug (quantitative difference) may not align with the data in the original meta-analyses.

RESULTS

The perception parameter exhibited a greater difference than anticipated (δ - 0.889), while the threshold for differentiating between the drugs was lower (τ - 1.001). The response pattern only aligned with theory by 44.37%. The dispersion of responses was associated with the length of work experience.

CONCLUSION

The perceived difference between the drugs significantly deviates from the theoretical data, both in terms of strength of perception and pattern (quantitative and qualitative differences).

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.

Experiences of Master of Nursing Education Students in Their Pursuit of Nursing Education

BACKGROUND

There is a growing concern in nursing education related to the shortage of nursing faculty. The experiences of nursing students, including their relationships with nursing faculty, could influence their decision to pursue graduate studies or academic nursing education.

METHOD

This phenomenological study explored the experiences of Master of Science in Nursing education students and graduates that led them to pursue nursing education. Semistructured interviews were conducted with 10 participants.

RESULTS

Based on participants' responses, five themes emerged: (1) faculty encouragement, mentoring, and enthusiasm; (2) teaching experience; (3) exposure to the faculty role; (4) awareness of the nurse faculty shortage; and (5) funding.

CONCLUSION

Findings from this study contribute to nursing education by highlighting strategies that could be reinforced into graduate or possibly undergraduate experiences to encourage students to pursue advanced study and academic nursing education, which potentially could help mitigate the nursing faculty shortage.

Schizophrenia patients with a metabolically abnormal obese phenotype have milder negative symptoms

BACKGROUND

Schizophrenia patients with a metabolically abnormal obese (MAO) phenotype have been shown poor cardiovascular outcomes, but the characteristics of their current psychiatric symptoms have not been characterized. This study mainly explored the psychiatric symptoms of schizophrenia patients with the MAO phenotype.

METHODS

A total of 329 patients with schizophrenia and 175 sex- and age-matched people without schizophrenia from Anhui Province in China were enrolled. The Positive and Negative Syndrome Scale (PANSS) was used to evaluate the mental symptoms of the schizophrenia patients. The MAO phenotype was defined as meeting 1-4 metabolic syndrome criteria (excluding waist circumference) and having a body mass index (BMI) ≥ 28 kg/m². And, metabolically healthy normal-weight (MHNW) phenotype was defined as meeting 0 criteria for metabolic syndrome and 18.5 ≤ BMI < 24 kg/m².

RESULTS

Overall, 15.8% of the schizophrenia patients and 9.1% of the control group were consistent with the MAO phenotype, and the prevalence of MAO in the schizophrenia group was higher than that in the control group. Among the patients with schizophrenia, the MAO group had lower negative factor, cognitive factor and total PANSS scores than the MHNW group. However, when confounding factors were controlled, only the negative factor remained lower significantly.

CONCLUSION

We found that schizophrenia patients with the MAO phenotype had reduced negative symptoms, which may indicate an internal mechanism linking metabolic disorders and negative symptoms.

Clinicians' views of treatment types for first episode psychosis delivered in a randomised controlled trial (MAPS)

BACKGROUND

Clinicians' treatment beliefs could affect the feasibility of delivering different treatments in a randomised controlled trial (RCT). In MAPS (Managing Adolescent first Episode Psychosis: a feasibility Study), adolescents with first episode psychosis (FEP) were randomly allocated to receive either antipsychotic medication (AP), psychological intervention (cognitive behavioural therapy [CBT] and family intervention [FI]), or both. We conducted a nested qualitative study to investigate clinicians' views of these treatments.

METHODS

Purposive sampling identified seventeen clinicians from CAMHS and Early Intervention services with prescribing responsibilities for 14-18 year olds at three participating MAPS sites. Individual participants were interviewed to examine their views of treatments in the MAPS trial. Interview transcripts were analysed using inductive Thematic Analysis.

FINDINGS

Clinicians viewed the decision to refer adolescents to the MAPS trial as requiring careful clinical judgement. Assessment complexity and diagnostic uncertainty had to be balanced against the urgency for treatment to reduce risk and distress. Underlying influences including duty of care and treatment beliefs underpinned decisions. Clinicians consistently valued AP as the primary treatment for FEP, with CBT and/or FI seen as helpful secondary treatment options. Nevertheless, the potential harms of prescribing AP, or not, to such a young population were highlighted as being of concern in treatment decision-making, and fostered reluctance to refer into a RCT.

INTERPRETATION

The design and delivery of RCTs involving young people experiencing FEP should consider the views of responsible clinicians, recognising that perceived treatment urgency, limitations in diagnostic precision, and existing treatment beliefs may influence trial processes.
