Financial Incentives to Improve Acceptance of Antipsychotic Injections

Schizophrenia Clinical Trial

Official title: Financial Incentives to Improve Acceptance and Adherence to Depot Injection Anti-psychotic Medication in Treatment Avoidant and Non-adherent Patients - a Pilot Study

Status Not yet recruiting

Clinical Trial Summary

There is a lack of incentive approach for patients who suffer from schizophrenia yet lack the insight to accept treatment. Most existing approaches involve coercion and involuntary hospitalizations. This study will explore whether patients with poor insight and lacking in competence for treatment decisions will improve their acceptance and adherence of depot injection antipsychotic medication if a financial incentive is offered. Ethical considerations are also explored for this innovative pilot study

Clinical Trial Description

Background: Medication adherence in patients with schizophrenia is a major challenge. For those who do come into contact with treatment services, various clinical and psychosocial approaches to improve antipsychotic medication adherence have been studied but none is very successful. People with severe psychotic illness often have poor insight into their illness, and lack competence for treatment decisions, making them very vulnerable to frequent illness relapses due to inadequate or lack of treatment. Furthermore, to compel them to receive treatment out of concerns for their own and others' safety and welfare, they are often subjected to involuntary hospitalization and community based treatments, by means such as Community Treatment Orders (CTO). Under the authority of CTO, patients need to take medication or they will be forcefully brought to the hospital for assessment and or hospitalization. There is concern for the coercive nature of these means that may harm these patients' relationship to the psychiatric system, and overall quality of life. There is well found concern for potential violation of the ethical principle of "do no harm", particularly when less coercive, easy to understand alternatives - such as financial incentives to take medication - have not been well explored. This study aims to assess financial incentive as a promoter of medication adherence in the most medication resistant patient population.

Methods: In a randomized cross-over study, the investogators will study medication adherence by focusing exclusively on a form of medication that is accurately measureable - the long-acting injectable antipsychotic medication. Participants will be recruited from the 160 patients who are currently enrolled at the St. Michael Hospital's Assertive Community Treatment team (FOCUS). Any patient who has had less than 75% adherence rate of his/her injectable antipsychotic depot medication in the last 4 months will be recruited. There are estimated 20-30 patients who would meet the inclusion criteria. Ten patients will be randomly assigned to each arm of the cross-over study. The treatment A arm would be offered the intervention of a $15 incentive to take the injectable medication. The treatment B arm would be treatment as usual as per FOCUS services. Each phase of the cross-over study would last 9 months - i.e. the cross-over would take place after 9 months. The primary outcome will be depot medication adherence levels, comparing the adherence rates in the treatment as usual phase. The secondary outcomes will be global clinical improvement, number of voluntary and involuntary hospital admissions and Emergency Room visits, number of police and justice system encounters, number of attempted and completed suicides, incidents of physical violence, number of days spent in work/education/rehabilitation programs, subjective quality of life and satisfaction with medication. The investigators will also study the cost effectiveness of offering financial incentives.

Discussion: The pilot study aims to provide new evidence on the effectiveness and cost effectiveness of offering financial incentives as an alternative to existing coercive approaches to improving medication adherence for patients with severe psychotic disorders. If found effective, and the benefits outweigh the risks, the potential to expand the practice, under strict ethical considerations and monitoring, at a larger policy and as an optional, available service improvement tool, is anticipated to be large. This will be the first known Canadian study on the subject. ;
