ABSTRACT
Background: Psychiatric-mental health nurse practitioners (PMHNPs) in the Netherlands have been allowed to perform the role of coordinating practitioner (CP) since 2018. This role is reserved for mental health care specialists
who are trained and qualified at the master’s degree level. Earlier studies have not addressed how PMHNPs perform that role and what mechanisms and contextual factors determine their performance. This understanding could help
optimize their performance in this role and promote effective deployment of PMHNPs in mental health care.
Purpose: To understand how PMHNPs perform this role and what mechanisms and contextual factors underlie that performance.
Methodology: A multiple case study involving PMHNPs who work in various settings as CPs. Data were collected and analyzed using the realistic evaluation approach.
Results: We identified four mechanisms related to the performance of PMHNPs in the role of CP: (1) autonomous performance; (2) unique expertise; (3) accessibility, availability, and professional involvement; and (4) additional
roles. The extent to which these mechanisms are present is largely determined by organizational factors, team factors, and individual factors.
Conclusions: Psychiatric-mental health nurse practitioners are seeking to identify and interpret the role of CP. This study helps to elucidate the mechanism of role performance by PMHNPs and what they should focus on to deliver
effective and patient-centered mental health care.
Implications: Policymakers, health care professionals, and educators should consider the mechanisms and con textual factors to facilitate and support PMHNPs’ employment and training in the role of CP.
