Abstract
Background
Antipsychotic medications are evidence-based treatments for schizophrenia that improve health outcomes and reduce costs. However, rates of non-adherence to oral antipsychotic medications can exceed 60%. We examined whether a simple checklist to identify individuals not receiving optimum benefit from current oral antipsychotic treatment (NOB Checklist) and The Multi-level Facilitation of Long-acting Antipsychotic Medication Program (MAP) could increase the appropriate use of long-acting injectable antipsychotic medication (LAI) in community clinics.
Methods
Two clinics in Texas and two in Ohio changed clinical procedures in one of two ways 1) NOB only clinics--providers used a five-item checklist to identify individuals with schizophrenia on oral antipsychotics who were Not receiving Optimum Benefit from current treatment and may therefore benefit from a switch to LAI. 2) MAP- providers used the NOB checklist AND received MAP; MAP is a novel behavior change intervention designed to improve the identification of individuals who could benefit from LAI, improve their outcomes and reduce inappropriate use of resources associated with poor adherence. MAP targets 3 stakeholder groups 1) the consumer for whom peer specialists showed a video describing shared decision making and how to make a choice between tablets and injections, and provided a balanced shared-decision making tool to assist them in choosing medication route,2) the provider who received academic detailing describing various LAI options, how to make good offers as part of a shared decision making dialogue, and important benefits of LAI including the ability to disentangle efficacy versus poor adherence and to help individuals with cognitive and practical problems that lead to poor adherence, and 3) the administrators who received information on how LAI could improve outcomes for individuals and clinic processes, how to encourage the use of LAI among providers and how to provide regular feedback to providers about prescribing practices. The primary outcome was the percentage of LAI versus oral antipsychotic medication prescribed to individuals with schizophrenia.
Results
Higher NOB checklist scores were associated with an increased provider likelihood of LAI offers and increased consumer acceptance of LAI. All clinics increased use of LAI over time. In Texas, where MAP was fully implemented, the MAP clinic had greater use of LAI over time (eventually reaching about 50% of all antipsychotic use) vs. the NOB only clinic. In Cleveland, the patient stakeholder curriculum was not delivered and there was no significant difference in LAI use between MAP and NOB clinics.
Discussion
The NOB checklist appears to be a useful tool to help identify patients who might be appropriate candidates for LAI and the full MAP program may help clinicians and consumers to work together to optimize the appropriate use of LAI in outpatient settings. Implementation must be customized for clinics and workflows to determine which parts of the MAP program are practical and appropriate. Participation of consumer stakeholders may be essential to delivery of the MAP Program.
