Changes in adherence and treatment costs following initiation of oral or depot typical antipsychotics among previously non-adherent patients with schizophrenia

Antipsychotic prescribing of consultant forensic psychiatrists working in different levels of secure care with patients with schizophrenia

Aims and method To detect any differences in the antipsychotic prescribing practices of consultant forensic psychiatrists working in different levels of secure care with patients diagnosed with schizophrenia, and to identify potential reasons for any differences. Prescribing data were collected from four secure hospitals within one National Health Service trust. A questionnaire was sent to consultant forensic psychiatrists working at those hospitals as well as those working in the trust's community forensic services. Results Consultants working in high security prescribed more oral antipsychotics than consultants working in medium and low security, who prescribed more depot antipsychotics, as established via the prescribing data. The questionnaire provided insight regarding the reasons for these preferences. Clinical implications There were differences in the antipsychotic prescribing practices of consultant forensic psychiatrists working in different levels of secure care, and, overall, the rate of depot antipsychotic prescribing was lower than might be expected. Although it was positive that the rate of polypharmacy was low when compared with earlier studies, the lower-than-expected rate of depot antipsychotic prescribing has clinical implications.

Cross-sectional comparison of first-generation antipsychotic long-acting injections vs risperidone long-acting injection: patient-rated attitudes, satisfaction and tolerability

OBJECTIVES

The objective of this study was to compare patients' attitudes and satisfaction with medication and patient-rated tolerability between those prescribed a first-generation antipsychotic long-acting injection (FGA-LAI) and those prescribed risperidone long-acting injection (RLAI).

METHOD

A cross-sectional study of a representative sample of outpatients prescribed an FGA-LAI or RLAI for a minimum of 6 months and attending a depot clinic. Attitudes to medication were assessed by the Drug Attitude Inventory (DAI-30), tolerability was measured by the Liverpool University Neuroleptic Side Effect Rating Scale (LUNSERS) and satisfaction with antipsychotic medication was assessed by the Satisfaction with Antipsychotic Medication (SWAM) scale.

RESULTS

The RLAI (n = 28) and FGA-LAI (n = 39) groups did not differ in terms of mean age, sex, diagnosis and ethnicity. All individual LAIs were prescribed within British National Formulary limits. The most commonly prescribed FGA-LAI was flupentixol decanoate (n = 22). There was no significant difference between the RLAI and FGA-LAI groups in terms of mean total scores on the DAI-30, LUNSERS and SWAM or the tolerability subscales of the LUNSERS or the two subscales (treatment acceptability and medication insight) of the SWAM. In both LAI groups there was a low level of side effects (LUNSERS) and a generally positive attitude (DAI-30) and reasonable satisfaction (SWAM) with medication.

CONCLUSIONS

Patients treated with FGA-LAI and RLAI for at least 6 months did not differ in terms of patient-rated tolerability, attitudes and satisfaction with medication. The current design cannot determine whether differences would have been evident earlier on during treatment. These results should be regarded as preliminary and are subject to prescribing bias. Randomized studies avoid prescribing bias and are a superior way to compare specific LAIs. Ideally randomized studies should include patient-rated outcome measures including medication tolerability; assessment of side effects, efficacy and quality of life made by blinded raters; and additional objective side-effect data including changes in weight and key blood parameters.
