Comparison of hospitalization rates in schizophrenic patients on first generation versus second generation antipsychotic depots

Abstract

Introduction

There is limited data on the efficacy rates between first and second generation antipsychotic depots. One good indicator of efficacy is the rates of hospitalization. Some studies have shown that second generation depot antipsychotics significantly reduce hospitalizations rates as compared to conventional depots.

Objectives

Comparison of hospitalization rates for patients with schizophrenia on first and second generation antipsychotic depots.

Methods

A retrospective observational study was done by reviewing the records of an antipsychotic depot clinic in Essex, United Kingdom. A list of 47 patients enrolled and receiving depot antipsychotics was obtained. Their records were studied and hospital admission rates calculated.

Results

Of the 47 patients 11 were excluded as they were on depot antipsychotics for non-schizophrenic diagnoses.

Of the 36 patients with schizophrenia, 12 were on second generation and 24 were on first generation depots.

Amongst the 24 patients on first generation depots, 19 were male, 5 female and mean age was 52 years.

Of the 12 patients on second generation depots, 10 were male and 2 female and mean age was 46 years.

When comparing hospital admission rates between the 2 groups, the following data was noted (Table 1).

Conclusions

There is no difference in hospitalization rates between patients on first generation antipsychotic depots as compared to second generation antipsychotic depots.
