Discrepancy in Taiwanese psychiatrists' preferences for long-acting injectable antipsychotics across facilities: a nationwide questionnaire survey

Time to rehospitalization in involuntarily hospitalized individuals suffering from schizophrenia discharged on long-acting injectable antipsychotics or oral antipsychotics

BACKGROUND

Involuntarily hospitalized individuals suffering from schizophrenia often have a poorer prognosis after discharge.

OBJECTIVE

This study aimed to analyze time to rehospitalization within 6 months of discharge in involuntarily hospitalized individuals suffering from schizophrenia discharged on long-acting injectable antipsychotics (LAIs) or oral antipsychotics (OAPs). In addition, temporal trends in LAI use at discharge were explored.

METHODS

Involuntarily hospitalized individuals suffering from schizophrenia discharged from the study hospital between 2006 and 2019 (n = 806) were included in the analysis. Survival analysis was used to compare time to rehospitalization within 6 months of discharge between individuals discharged on LAIs and OAPs, and between first-generation antipsychotic (FGA) LAIs and second-generation antipsychotic (SGA) LAIs. The Cochran-Armitage trend test was used to test whether a temporal trend existed for LAIs use at discharge during the study period.

RESULTS

The LAIs group (n = 231) had a significantly lower rate of rehospitalization and a significantly longer time to rehospitalization than the OAPs group (n = 575). Rehospitalization rate and time to rehospitalization were not significantly different between individuals discharged on FGA-LAIs and SGA-LAIs. LAIs use at discharge grew significantly from 16.77% in 2006 to 50.00% in 2019 (Z = 6.81, p < 0.0001). Among all LAIs, only use of SGA-LAIs at discharge increased significantly (Z = 5.74, p < 0.0001), but not FGA-LAIs.

CONCLUSIONS

LAIs were superior to OAPs in preventing rehospitalization. However, SGA-LAIs were comparable with FGA-LAIs in reducing rehospitalization risk. Use of LAIs increased significantly in discharged involuntarily hospitalized individuals during the study period, especially SGA-LAIs.

Perceptions of Psychiatrists Toward the Use of Long-Acting Injectable Antipsychotics: An Online Survey Study From India

PURPOSE/BACKGROUND

Despite proven benefits of long-acting injectables (LAIs), these are frequently underused by the psychiatrists. Accordingly, this study aimed to explore the perceptions of psychiatrists toward the use of LAI antipsychotics in their routine clinical practice.

METHODS/PROCEDURE

An online e-mail survey was conducted by using Survey Monkey platform.

RESULTS

A total of 622 psychiatrists with a mean age of 41 years who were in psychiatric practice for approximately 14 years participated in the survey. Participants reported using LAI, mainly for patients with schizophrenia, with LAI prescribed to approximately one-tenth (9.30%) of their patients in acute phase of illness and in one-fifth (18.42%) of patients in stabilization/stable phase. Fluphenazine decanoate (32.7%) was the most commonly used LAI followed by flupenthixol decanoate (19.5%), haloperidol decanoate (17.8%), and olanzapine pamoate (11.1%). The most common reasons for starting LAI were history of medication (100%) and treatment (80.5%) nonadherence, followed by having frequent relapses/exacerbations of symptoms (54.8%). Overall, more than half of the participants felt the level of acceptance of LAI among patients offered to be quite reasonable (54.3%), and mostly, LAIs were used as combination therapy with oral antipsychotics (73.6%). Despite all these, approximately three-fifths (59%) of the participants reported that they underuse LAI to a certain extent, with most common reasons that deter them from using LAI being the cost (55.45%), lack of interest of patients in receiving LAI (42.9%), lack of regular availability (41.3%), and patients being scared of receiving injectables (41.2%).

CONCLUSIONS/IMPLICATIONS

The LAI antipsychotics despite having several benefits are still underused by a substantial proportion of practicing psychiatrists.

Time to Rehospitalization in Patients With Schizophrenia Receiving Long-Acting Injectable Antipsychotics or Oral Antipsychotics

BACKGROUND

This study aimed to investigate and compare time to rehospitalization in patients with schizophrenia receiving long-acting injectable antipsychotics (LAIs) after discharge with those receiving oral antipsychotics. Additionally, the trend of LAIs prescription rates was investigated.

METHODS

Patients with schizophrenia (n = 13 087), who were discharged from the study hospital from 2006 to 2017, were followed-up under naturalistic conditions in the year after discharge. The primary outcome was time to rehospitalization. Survival analysis was used in the comparisons between LAIs and oral antipsychotics and between FGA-LAIs and SGA-LAIs. Simple linear regression and Cochrane-Armitage trend test were used to test whether a time trend existed for LAIs prescription rates.

RESULTS

In the 1 year following discharge, patients in the LAIs group had a significantly lower rehospitalization rate and a significantly lengthened time to rehospitalization than those in the oral antipsychotics group. Rehospitalization rate and time to rehospitalization were not significantly different in patients receiving FGA-LAIs or SGA-LAIs. A significantly higher percentage of patients treated with FGA-LAIs received anticholinergic agents than those treated with SGA-LAIs. The LAIs prescription rate grew significantly from 2006 to 2017 by an average of 0.5% per year.

CONCLUSIONS

LAIs were significantly superior to oral antipsychotics in reducing rehospitalization risk, whereas SGA-LAIs were comparable with FGA-LAIs in reducing rehospitalization risk. However, use of concomitant anticholinergic agents was less frequent in the SGA-LAIs group than in the FGA-LAIs group. Increase in LAIs prescription rate may be due to growing experiences and success among clinicians in treating patients with LAIs.

Patients' experiences of long-acting injectable antipsychotics: a qualitative study

BACKGROUND

In this study, we applied a qualitative approach to explore patients' subjective experiences of long-acting injectable antipsychotics (LAIs).

METHODS

Patients undergoing psychiatric treatment from the chronic ward or outpatient department of a medical center in northern Taiwan who had experience with LAI treatment were enrolled. Information was obtained through semi-structured in-depth interviews. The interviews were audio-recorded and then translated verbatim, and the data were collected and analyzed concurrently to develop major themes and categories.

RESULT

In total, 14 participants (8 female) were interviewed. In a bio-psycho-social model, the participants used LAIs as a method to become "normal," in order to achieve a balance between the "effects" and "side effects" that may influence their daily lives. Their past experiences constructed their concepts about and expectations regarding LAIs, and their relationships with their family members and co-workers also modeled their experiences.

CONCLUSION

In our study, we sought to understand the experience of LAI in the daily life context of the patients. We attempted to use a bio-psycho-social model to evaluate the subjective experience of the patients; an improved understanding can help mental health specialists gain a closer insight into patient experience.
