Long-acting injectable antipsychotic (LAI) prescribing trends during COVID-19 restrictions in Canada: a retrospective observational study

The impact of COVID-19 public health measures on the utilization of antipsychotics in schizophrenia in Manitoba - A population-based study

PURPOSE

During the COVID-19 pandemic, public health measures were implemented, yet it is unknown whether these measures affected medication access in those with schizophrenia (SCZ). This study aimed to assess whether the antipsychotic utilization in SCZ changed during the pandemic.

METHODS

We used dispensed prescription drug data from the Canadian province of Manitoba in individuals with SCZ using linked administrative data from the Manitoba Population Research Data Repository. The quarterly incident and prevalent dispensation of antipsychotics at two periods were compared with the expected trend (April 1, 2015 to April 1, 2020 and 2021) using linear autoregression. We stratified the primary results by age and sex and examined multiple subgroups.

RESULTS

There were 9045 individuals with SCZ in the first fiscal quarter of 2020. The prevalent use of the most common antipsychotics were: olanzapine (206.7/1000), risperidone (190.8/1000), quetiapine (174.4/1000), and clozapine (100.9/1000). The overall prevalent use of antipsychotics remained stable during the pandemic compared with the expected trend. A significant decrease in the incident use in April-June 2020 (estimate: -1.3, 95%CI:-2.2,-0.3) was noted compared with the expected. A significantly higher incidence of atypical antipsychotics (estimate: 1.4, 95%CI: 0.2,2.5) and risperidone separately (estimate: 1.8, 95%CI: 0.2,3.3) was noted in 2021 compared with expected.

CONCLUSION

This study found a decline in the receipt of antipsychotics for people with SCZ during the initial implementation of COVID-19 public health measures, particularly on the overall incidence. Future work on investigating the impact of these trends on SCZ outcomes is needed to inform future pandemic-related policies.

Evaluating the impact of COVID-19 on medication adherence and health care utilization among individuals with psychotic disorders who are prescribed long-acting injectables (LAIs) or clozapine: A population-based study in Manitoba, Canada

BACKGROUND

Ongoing psychiatric follow-up and medication adherence improve outcomes for patients with psychotic disorders. Due to COVID-19, outpatient care may have been disrupted, impacting healthcare utilization.

METHODS

A retrospective population-wide study was conducted for adults in Manitoba, Canada. Medication adherence and healthcare utilization were examined from 2019 to 2021. The presence of a diagnosed psychotic disorder was identified in the five years before the index date in each year. The LAI and clozapine cohorts consisted of those who received at least two prescriptions in each year 180 days before the March 20th index date. The change in adherence was measured using the average Medication Possession Ratio. Healthcare utilization rates were compared using Generalized Estimating Equation models.

RESULTS

There were no significant differences between LAI and clozapine discontinuation rates before and during the pandemic. In the LAI cohort, general practitioner visits decreased significantly (-3.5 %, p = 0.039) across four quarters of 2021 versus 2019. All-cause hospitalizations decreased by 16.8 % in 2020 versus 2019 (p = 0.0055), while psychiatric hospitalizations decreased by 18.7 % across four quarters in 2020 (p = 0.0052) and 13.7 % in 2021 (p = 0.0425), versus 2019 in the LAI cohort. There was a significant transition to virtual care during the first wave of COVID-19 (71 % in clozapine, 51 % in LAI cohorts). Trends in total outpatient visits and non-psychiatric hospitalizations remained stable.

CONCLUSION

COVID-19 had no substantial impact on LAI and clozapine discontinuation rates for patients previously adherent. Outpatient care remained stable, with a significant proportion of visits being done virtually at the outset of the pandemic.

Long-acting injectable antipsychotics as maintenance therapy for schizophrenia during the COVID-19 pandemic: A micro-narrative review

The coronavirus disease pandemic has presented healthcare systems with unprecedented challenges globally and substantially impacted the management of chronic diseases such as schizophrenia. This narrative review highlights the usefulness of long-acting injectable antipsychotics (LAIs) as maintenance therapy for patients with schizophrenia during the pandemic. The analysis of relevant literature and psychiatric survey data revealed diverse trends in LAIs prescription and patient adherence with oral antipsychotics. Although some studies have reported a decrease in LAIs prescriptions owing to pandemic-related disruptions, others have suggested stable patient adherence with oral antipsychotics. Approximately 70% of Japanese psychiatrists reported an increase in schizophrenia relapse rates in a survey, underscoring the critical role of LAIs in maintaining therapeutic stability. The potential benefits of LAIs with extended dosing intervals have been highlighted, including improving oral medication adherence and reducing the frequency of hospital visits. In conclusion, this review emphasizes the continued need for uninterrupted LAIs therapy in conjunction with community and home-based care despite the disruptions caused by the coronavirus disease pandemic. Further development of LAIs maintenance therapy strategies considering the ongoing pandemic and potential future public health emergencies are required.

Depression and stress levels in patients with different psychiatric disorders during concurrent early-phase COVID-19 pandemic and earthquake in Croatia

BACKGROUND

While Croatia shared COVID-19 pandemic with other countries, its capital area was also hit by a 5.6 magnitude earthquake. The simultaneous impact of these two disasters on psychiatric patients is largely unknown, and we addressed those knowledge gaps.

METHODS

The cross-sectional study was conducted during the pandemic's first peak, in the aftermath of earthquake, by telephonic survey. Measurements included the Patient Health Questionnaire-9, the Perceived Stress Scale and the semi-structured interview to evaluate the impact of pandemic stress and earthquake. Overall 396 patients with depression and/or anxiety disorders (DAD), 229 participants with schizophrenia spectrum disorders (SSD) and 205 healthy controls were enrolled.

RESULTS

Both patient groups had higher depression and stress levels than controls, independent of sex, age and the presence of somatic comorbidity. After controlling for the same covariates, patient groups had higher COVID-19- and earthquake-related fears than controls. In patients with DAD, both fears were greater than among SSD patients. When comparing the two fears, the fear from earthquake was higher in DAD and control groups, whereas in SSD patients there was no such difference.

CONCLUSIONS

Patients with DAD were the most vulnerable group during disasters, while earthquake seems to be associated with more fear than the pandemics, at least in DAD patients and healthy individuals. Future longitudinal studies should determine if early psychological support might alleviate stress levels after disasters and prevent further worsening of mental health, particularly among DAD patients.

Short communication: Prevalence of long-acting injectable antipsychotic use in Canadian early intervention services for psychosis

The use of long-acting injectable (LAI) antipsychotic drugs for psychotic disorders in Canada has been historically low compared to other jurisdictions despite advantages of LAIs in improving medication adherence and preventing relapse. In response, treatment recommendations were developed in 2013 by the Canadian Consortium for Early Intervention in Psychosis and other Canadian provincial expert groups. The impact of these guidelines needed to be assessed. To document practices in LAI use in early intervention services (EIS) for psychosis, Canadian EIS were surveyed in 2016 (n = 18) and 2020 (n = 12). Trends and descriptive information were examined using repeated cross-sectional survey data. Eight EIS responded to surveys at both time points allowing for longitudinal comparisons. Outcomes of interest included i) LAI use frequency, ii) timing of LAI starts, and iii) factors influencing LAI use. Cross-sectional analysis identified a significant increase in overall LAI usage (24.7% in 2016; 35.1% in 2020). Longitudinal analysis indicated that patients in the second program year saw the greatest increase in LAI use between 2016 and 2020 (25.6% vs. 36.1%), especially among patients under community treatment orders (65.5% vs. 81.5%). Results support increases in LAI use over time, accessibility, awareness, and increasing comfortability among Canadian clinicians.

Lessons from the coronavirus disease 2019 pandemic in schizophrenia: a review

PURPOSE OF REVIEW

Multiple countries have reported increased COVID-19 mortality in patients with schizophrenia. The purpose of this review was to synthetize the consequences of the pandemic on patients with schizophrenia including vaccination data.

RECENT FINDINGS

We have synthetized data on the increased risk of infection and increased mortality, the impact of the pandemic and lockdowns on psychiatric care, vaccination policies, unwillingness to vaccine in patients and the rates of vaccination.

SUMMARY

Schizophrenia has been confirmed at increased risk of both COVID-19 infection and developing a severe/lethal form of the infection. Patients with schizophrenia should, therefore, be prioritized for vaccination whenever possible and should be prioritized for psychiatric and somatic care access. Psychotic symptomatology may be a barrier to vaccination in some patients, and heterogenous vaccination rates were identified in national databases. The COVID-19 pandemic has been also a unique opportunity to develop telehealth. A mixed face-to-face and distance model should be encouraged, whenever possible, to improve the experience of patients, relatives and healthcare professionals. No major change of long-acting antipsychotics has been reported in most countries, and there was no consistent evidence for clozapine prescription to increase the risk of COVID-19 infection or severe outcomes.

Use of Long-Acting Injectable Antipsychotics in a Clinical Sample of Community-Dwelling Patients with Schizophrenia-Spectrum Disorders in Rural Greece

Data on the use of long-acting injectable antipsychotics (LAIs) in rural community mental healthcare settings are scarce. This study aimed to investigate the prescription patterns of LAIs in a clinical sample of patients with schizophrenia-spectrum disorders in rural Greece. All patients with schizophrenia-spectrum disorders who regularly attend the Mobile Mental Health Unit of the prefectures of Ioannina and Thesprotia (MMHU I-T) in northwestern Greece were included in the study. The sample consists of 87 patients (59 males and 28 females) with a mean age of 54.4 years and a mean illness duration of 28 years. Most patients (72.4%) received antipsychotic monotherapy, and nearly 30% received an LAI formulation, mostly a second-generation LAI (20 of 26 patients, 76.9%). The treatment regimen comprised benzodiazepines in one-third of the patients and antidepressants in one-quarter. There was no statistically significant association between treatment regimen and the clinical and demographic variables studied, except for biological sex (female). The percentage of patients treated with LAIs in this study was almost three times higher than the rate previously reported in Greece and is higher than the rates reported in other countries. Patients with schizophrenia-spectrum disorders in rural Greece may have adequate access to innovative treatment with second-generation LAIs. Further research is needed to demonstrate the cost-effectiveness of LAI treatment in rural communities and to elucidate the factors associated with such treatment.

Long-acting Injectable Antipsychotics during the COVID-19 pandemic in schizophrenia: An observational study in a real-world clinical setting

The COVID-19 pandemic is having an important impact on the practice of mental health services and on schizophrenia patients, and heterogeneous and conflicting findings are being reported on the reduction of long-acting injectable (LAI) antipsychotics use. Aims of the study were to assess the total number of patients treated with LAI, the start of novel LAI and the discontinuation of LAI treatments, analyzing register data of the first year of the pandemic, 2020, compared to a pre-pandemic reference year, 2019. Data from two outpatient centers were retrieved, for a total of 236 participants in 2020: no significant differences were observed comparing 2020 and 2019 when considering the total number of patients on LAI treatment (p = 0.890) and the number of dropouts (p = 0.262); however, a significant reduction in the start of LAI was observed (p = 0.022). In 2020, second generation LAI were more prescribed than first generation LAI (p = 0.040) while no difference was observed in 2019 (p = 0.191). These findings attest the efficacy of measures adopted in mental health services to face the consequences of COVID-19 and shed further light on the impact of the pandemic on the clinical practice of mental health services and on the continuity of care of people with schizophrenia.

Canadian Healthcare System and Individuals with Severe Mental Disorders During Coronavirus Disease 2019: Challenges and Unmet Needs

The Coronavirus Disease 2019 (COVID-19) pandemic is a syndemic of viral infection and mental health adversity. The pandemic has exacerbated inequalities of access to care in vulnerable populations within the Canadian mental healthcare system. Primary care services are first-line health services in Canada, and are necessary to access specialized services. However, as a result of the limited availability of primary health services, and subsequently, specialized providers (eg, psychiatrists), the demand for these services outweigh the supply. Hitherto, timely access to appropriate services has been cited as a common challenge in Canada as a result of limitations as it relates to resources and in-person activities and support services. While there has been an increase in virtual care opportunities, concerns have been raised with respect to the digital divide. Moreover, while individuals with serious mental illness (SMI) and psychosis are at an increased risk for hospitalization and death from COVID-19, testing and vaccination services have not been prioritized for this population. Taken together, increased funding for mental health service delivery should be emphasized especially for individuals with SMI. There should also be a focus on increased collaboration among individuals with lived experience and health care providers to ensure future policies are developed specifically for this population. Addressing the social determinants of health and prioritizing a continuum of care across various stakeholders may lead to strong integration of care both during and after the pandemic.

Long-Acting Injectable Antipsychotics (LAIs) Prescribing Trends during the COVID-19 Pandemic in Romania

Long acting injectable antipsychotics (LAIs) are considered the ideal treatment for schizophrenia, especially for young patients with high rates of non-adherence. In the current COVID-19 pandemic, it has been reported that the administration of LAIs decreased in some areas. The aim of this study was to evaluate the impact of COVID-19 pandemic on the initiation of LAIs. This is a retrospective mirror- image study covering a total period of 24 months: 12 months before and 12 months after the declaration of COVID-19 pandemic on March 11, 2020. During the study period, out of 218 patients admitted with schizophrenia, only 15 (1.3%) received LAIs at discharge. There was a 48.3% reduction in LAIs initiation compared to the pre-pandemic period (29 LAIs initiations in 2019 from 224 admissions). Despite the 27% reduction in the total number of admissions (1500 in 2019 vs. 1100 in 2020), the number of admissions with schizophrenia remained almost the same (224 in 2019 vs. 218 in 2020). COVID-19 pandemic brought an important challenge in the treatment of patients with schizophrenia, especially in the initiation of LAIs. This could have an important impact on the relapse rate in the next period.

The Impact of the COVID-19 Pandemic on the Lifestyles and Levels of Anxiety and Depression of Patients with Schizophrenia: A Retrospective Observational Study

The movement restrictions put in place as a result of the COVID-19 pandemic required modification of the population’s usual routines, including those of the most vulnerable groups such as patients with schizophrenia. This was a retrospective observational study. We used an online survey to collect information on patient adherence to the Mediterranean diet (Mediterranean Diet Adherence Screener questionnaire), physical exercise (International Physical Activity Questionnaire Short Form), and tobacco consumption and levels of anxiety and depression (Hospital Anxiety and Depression Scale) before and during the movement restrictions. A total of 102 people with schizophrenia participated in this study. During the COVID-19 pandemic lockdown the participants significantly increased the number of minutes spent sitting per day (z = −6.73; p < 0.001), decreased the time they spent walking (z = −6.32; p < 0.001), and increased their tobacco consumption (X² = 156.90; p < 0.001). These results were also accompanied by a significant increase in their reported levels of anxiety (z = −7.45; p < 0.001) and depression (z = −7.03, p < 0.001). No significant differences in patient diets during the pandemic compared to before the movement restrictions were reported. These results suggest the need to implement specific programs to improve lifestyle and reduce anxiety and depression during possible future pandemic situations.

Results from PSIPROSPER: A multicenter retrospective study to analyze the impact of treatment with paliperidone palmitate 1-month on clinical outcomes and hospital resource utilization in adult patients with schizophrenia in Portugal

BACKGROUND

Schizophrenia is a chronic psychiatric disorder with a significant impact worldwide. The early onset and its relapsing nature pose a significant challenge to patients and caregivers. The PSIPROSPER study aimed to characterize the real-world context of schizophrenia treatment in Portugal and to measure the impact of including paliperidone palmitate 1-month formulation (PP1M) in the clinical outcomes (relapses and hospitalizations) and healthcare resource utilization, in a context in which payment scheme in Portugal allows for patients to receive free antipsychotics if prescribed at public hospitals.

METHODS

This was a multicenter, retrospective, observational study. Male and female adults with a diagnosis of schizophrenia who initiated treatment with PP1M after a minimum of 12 months on an Oral Antipsychotic (OAP), and with complete medical charts, were consecutively included. A mirror-image design over 24 months allowed the comparison of outcomes before and after the PP1M introduction.

RESULTS

Out of the 51 patients included, 80.4% were male, with a mean age of 34 (±9.8) years. Around 92% of patients were being treated with PP1M at inclusion. Lack of adherence to previous OAP was the main driver for PP1M initiation. Only 9.8% of patients were hospitalized during the PP1M period vs. 64.7% during the OAP period (p < 0.0001). The mean number of hospitalizations (0.1) was significantly lower during the PP1M period (p < 0.0001). Type of treatment was the only variable found to be significant in predicting a lower hospitalization rate and a lower risk of hospitalization. Relapses were significantly lower (p < 0.0001) in PP1M (21.6%) vs. OAP (83.7%). Similarly, the mean change in the number of relapses (p < 0.0001) showed significantly better outcomes in PP1M.

CONCLUSION

This study supports PP1M as part of schizophrenia treatment in Portugal. Given the lower number of relapses and hospitalizations observed in schizophrenia patients treated with PP1M when compared to OAP-treated patients, this real-world study seems to provide further evidence to support the use of PP1M to treat this condition, in line with previous research. In the context of scarce public resources, these benefits should be carefully considered by healthcare decision-makers to ensure optimal value-based treatment strategies.
