Objective

To describe an injectable extended-release antipsychotic pharmacotherapeutic follow-up program and to assess adherence among patients included in the program.

Method

A coordinated program is described involving hospital and primary care pharmacy, which included electronic prescription, reviewing, and dispensing of injectable antipsychotic agents in mental health and primary health care centers. Adherence to treatment was assessed in a 1-month prospective observational cross-sectional study which included all patients under treatment with injectable extended-release antipsychotics in a health area of more than 500,000 inhabitants. The variables collected were: medication administered, frequency of administration, administration center, and whether or not the patient attended the center. Patients were considered to have adhered to treatment if they had attended their appointments within a margin of ± 7 days.

Results

A total of 919 patients and 1,073 appointments were included. Eleven mental health units and 40 primary health care centers participated in data collection. In 95.7 % (1,027) of cases, the patients attended the appointment. No differences were found in adherence between drugs or administration frequency. However, differences were found between mental health units and primary health care centers. Patient adherence was slightly higher in mental health units (97.6% vs 91.1%; P < 0.001).

Conclusions

The high adherence rate shows that the described follow-up program is effective. Further long-term studies are needed to confirm this trend.
