Expanding the Role of Psychiatric Mental Health Nurse Practitioners in a State Psychiatric System: The New Hampshire Experience

The New Hampshire state mental health system mainly consists of ten community mental health centers (CMHCs) and New Hampshire Hospital (NHH).

CMHCs provide community mental health services to approximately 48,000 individuals annually. These services, including treatment offered to approximately 19,000 individuals deemed severely mentally disabled, are currently being provided by both psychiatrists and PMHNPs. There are 303 psychiatrists and 270 PMHNPs licensed to practice in New Hampshire. Of those, 72 psychiatrists and 49 PMHNPs work in the ten CMHCs and NHH.

NHH is a 158-bed state psychiatric hospital that treats individuals admitted involuntarily because they are a danger to themselves or others as a result of mental illness. NHH admits approximately 2,400 patients a year. NHH inpatient unit treatment teams were historically led by psychiatrists, but over the past decade an increasing number of PMHNPs have taken on roles as treatment team leaders.

An important legislative event occurred in 2001, when New Hampshire established a legal definition of a PMHNP. This New Hampshire statute officially named the PMHNP as an advanced practice registered nurse (APRN) and stated that “an APRN means an advanced practice registered nurse licensed by the board of nursing who is certified as a psychiatric mental health nurse practitioner by a board-recognized national certifying body” (15). Defining an APRN in a New Hampshire statute was important, because it allowed for future legislation to clearly refer to these well-trained clinicians, preventing confusion for future policy makers. In 2001, the same legislation authorized APRNs to evaluate and sign paperwork in emergency rooms, allowing individuals to be sent to NHH on an initial three-day involuntary emergency admission. Before that, only physicians were allowed to perform this clinical duty.

In 2005, the New Hampshire legislature significantly revised the Nurse Practice Act, stating that APRNs’ scope of practice was “limited to performing acts of advanced assessment, diagnosing, prescribing, selecting, administering and providing therapeutic measures and treatment regimens; obtaining consultation, planning, and implementing collaborative management, referral, or transferring the care of the patient as appropriate; and providing such functions common to a nurse practitioner for which the APRN is educationally prepared and which are consistent with standards established by a national credentialing or certification body recognized by the National Council of State Boards of Nursing and approved by the board in the appropriate APRN role and specialty” (16). This revision allowed APRNs to be independent practitioners and treat outpatients without physician supervision. At NHH, APRN treatment team leaders continue to work collaboratively and in consultation with a supervising psychiatrist regarding a patient’s overall plan of care.

New Hampshire statute allows individuals to be committed involuntarily to NHH for a maximum of five years. Many patients are committed for much shorter stays and subsequently released on a conditional discharge, wherein they have to abide by certain conditions (such as taking medications as prescribed and keeping all outpatient appointments with their psychiatrist or APRN) when out of the hospital. If they don’t follow these conditions, they can be sent back to NHH through a revocation of their conditional discharge. In 2008, a change in New Hampshire’s Administrative Rules of the General Court authorized APRNs to sign the conditional release papers allowing patients to be released from NHH and also permitted APRNs who are treating patients as outpatients in CMHCs to send patients back to NHH on a revocation of their conditional discharge if a patient was not following his or her agreed-upon treatment plan. Before that rule change, only psychiatrists were able to perform these clinical duties (17).

Administrative Rules of the General Court of New Hampshire allow for patients committed to NHH involuntarily by a probate court to be treated involuntarily for up to 45 days if, after a petition is written and submitted and a hearing is held, proof is shown by clear and convincing evidence that a psychiatric emergency exists. In 2014, a rule change authorized APRNs to write and submit the petition and testify at such hearings. Before that rule change, only psychiatrists were able to write and submit these petitions and testify at these hearings (18).

In 2015, legislation authorized APRNs to request long-term psychiatric commitments to NHH for patients for up to five years. Furthermore, if patients had a guardian and the guardian requested that his or her ward be admitted voluntarily to NHH, APRNs were allowed to sign patients into NHH voluntarily with the guardian’s consent. Before that statute change, only psychiatrists were allowed to perform these clinical duties (19).

These incremental although extremely important statute and rules changes have allowed New Hampshire APRNs increasing opportunities to effectively treat patients with the most severe mental illness. These changes also expanded APRNs’ ability to work in the public sector, allowing an increasing number of prescribers the ability to treat our most vulnerable patient population. APRNs are no longer seen as “mid-level practitioners” or “physician extenders” but as clinician colleagues.

The New Hampshire mental health system has integrated APRNs into clinical leadership roles. Legislative changes have allowed them to demonstrate their ability to direct treatment teams caring for complex, clinically challenging outpatients and involuntarily hospitalized inpatients deemed to be a danger to themselves or others as a result of mental illness. Two factors led to this change: the realization by clinical and administrative leaders in CMHCs and NHH of APRNs’ capacity to take on these responsibilities and the development of a coherent, organized, and proactive legislative strategy by nurses and physician leaders advocating for changes to New Hampshire statutes and rules leading to the incremental expansion of APRNs’ clinical authority. Such success would not have been possible without APRNs’ demonstrating their clinical effectiveness and working closely with physician leaders and policy makers to ease passage of state statutes and rules allowing this to happen. Other states may consider this strategy, thus allowing increasing numbers of prescribers the opportunity to treat vulnerable patient populations.
