CLINICAL & COMPARATIVE GUIDE

PHP vs. IOP vs. Inpatient:
Which Level of Care Is Right for You?

A clinician-reviewed decision guide for individuals, families, and referring providers navigating the behavioral healthcare continuum in Massachusetts.

Why the ‘Right Level of Care’ Question Matters More Than You Think

Every year, thousands of Massachusetts families make one of two costly errors when confronting an acute mental health crisis. The first is under-treating: continuing with weekly outpatient therapy when the clinical situation has escalated beyond what one 50-minute session per week can contain. The second is over-treating: defaulting to inpatient hospitalization when a less disruptive, equally effective, and substantially less traumatizing level of care could achieve the same stabilization goal.

Both errors carry real clinical and human costs. Under-treatment allows deterioration to compound, often resulting in a far more acute crisis — and a far more restrictive level of care — several weeks later. Over-treatment, while well-intentioned, can cause secondary institutional trauma, severe disruption to employment and family life, and paradoxically slower long-term recovery by removing an individual from their natural support systems at a critical moment.

The behavioral healthcare continuum exists precisely to match clinical intensity to clinical need. This guide provides the detailed, evidence-based framework that individuals, families, and referring providers need to understand exactly where each level of care begins, where it ends, and — critically — how to recognize the clinical signals that indicate it is time to move.

The four levels of care covered in this guide — Traditional Outpatient, Intensive Outpatient (IOP), Partial Hospitalization (PHP/Day Treatment), and Inpatient Hospitalization — are defined by the Centers for Medicare & Medicaid Services and adapted by commercial insurers operating in Massachusetts under the federal Mental Health Parity and Addiction Equity Act. Understanding these definitions gives families a common clinical language for navigating conversations with providers, insurers, and care teams.

For the full clinical definition of Partial Hospitalization and what it means in practice, see our parent guide: The Ultimate Guide to Psychiatric Day Treatment in Massachusetts.

WHO THIS GUIDE IS FOR

This guide is designed for three audiences: (1) individuals who are experiencing active psychiatric symptoms and trying to understand what level of care is appropriate for their situation; (2) family members and caregivers supporting a loved one who is in crisis or approaching one; and (3) referring providers — primary care physicians, outpatient therapists, school counselors — who need a clear clinical framework for determining when a referral to a higher level of care is indicated.

If you or a loved one is in immediate danger, please call 911 or proceed to your nearest emergency room. For a mental health crisis without immediate danger, call or text 988 (the Suicide and Crisis Lifeline). This guide is an informational resource, not a substitute for a formal clinical assessment.

The Behavioral Healthcare Continuum: A Clinical Framework

The behavioral healthcare system is best understood not as a set of discrete, unrelated services but as a coordinated continuum — a clinical pyramid in which movement upward represents increasing medical intensity and oversight, and movement downward represents increasing autonomy and community integration. Each level has a defined clinical purpose, a defined target patient population, and defined criteria for admission and discharge.

Traditional Outpatient Therapy

Traditional outpatient therapy — the weekly or biweekly appointment with a licensed therapist or psychiatrist — represents the foundation of the behavioral healthcare continuum. It is the appropriate level of care for the vast majority of people who experience mental health symptoms: those who are functionally intact across the major domains of daily life (employment or school, social relationships, self-care, and physical health) but who benefit from structured support, skill-building, and psychological processing.

  • Clinical Hours Per Week: 1 to 2 hours. The clinical contact is intentionally low — the goal is to develop insight and skills that the patient applies independently during the remaining 166+ hours of the week.
  • Psychiatric Access: Monthly or bi-monthly medication management appointments for patients on psychiatric medications, or referrals to a separate psychiatrist for medication oversight.
  • Target Population: Individuals with mild to moderate symptoms who are functionally stable, or those in long-term maintenance treatment following stabilization at a higher level of care.
  • Primary Limitation: Traditional outpatient is not designed to manage acute psychiatric crises. A therapist seeing a patient once per week has limited capacity to monitor rapid symptom changes, adjust medications, or provide the intensive, structured skills training that acute destabilization requires.

CLINICAL SIGNAL: WHEN OUTPATIENT IS NO LONGER SUFFICIENT
Your current therapist or psychiatrist has expressed concern that weekly sessions are not containing your symptoms. You are canceling or missing appointments because your symptoms make it difficult to keep commitments. Your functioning at work, school, or home has visibly declined over several consecutive weeks. You have visited an emergency room or urgent care for a mental health concern in the past 90 days. If two or more of these describe your situation, a formal assessment for a higher level of care is clinically warranted.

Intensive Outpatient Program (IOP)

The Intensive Outpatient Program represents the first step above standard outpatient care on the clinical intensity pyramid. IOP occupies a critical but frequently misunderstood position: it is not simply “more therapy” — it is a structured, multi-modal clinical program that provides substantially more clinical contact, group-based skills training, and psychiatric oversight than traditional outpatient care, while still allowing patients to live independently and maintain most daily responsibilities.

  • Clinical Hours Per Week: 9 to 15 hours. Programs typically run three to five days per week, three to four hours per session, often available in morning, afternoon, or evening schedules to accommodate work and school.
  • Psychiatric Access: Weekly or biweekly psychiatric consultations for medication evaluation and adjustment.
  • Primary Modalities: Group therapy (CBT, DBT, or psychoeducational groups), individual therapy (weekly), and family involvement sessions as clinically indicated.
  • Target Population: Two distinct groups — (1) individuals stepping down from PHP or inpatient who need continued structured support before returning to independent outpatient care, and (2) individuals with elevated symptoms that outpace standard outpatient capacity but who retain sufficient daily functioning to manage a part-time clinical schedule.
  • Primary Limitation: IOP does not provide daily psychiatric monitoring. For individuals whose medication regimens require frequent adjustment, or whose safety profile requires daily clinical check-ins, IOP’s weekly psychiatric access is insufficient.

For a complete walkthrough of the PHP daily schedule and first-day experience, see: What to Expect on Your First Day at PHP.

Inpatient Psychiatric Hospitalization

Inpatient psychiatric hospitalization sits at the apex of the behavioral healthcare continuum — the highest possible level of clinical intensity. Inpatient care is designed for one specific clinical situation: when an individual poses an active, imminent danger to themselves or others that cannot be safely managed in a community setting, or when a medical psychiatric condition requires 24-hour nursing oversight for physiological stabilization (such as severe medication toxicity, catatonia, or psychiatric symptoms secondary to a medical emergency).

  • Clinical Hours Per Week: 168 hours (continuous). The patient resides on a locked or semi-locked psychiatric unit with 24-hour nursing, medical, and psychiatric coverage.
  • Primary Goal: Rapid safety stabilization and containment. Inpatient care is not primarily a treatment platform for long-term psychological growth — it is an acute medical intervention designed to resolve the immediate safety crisis.
  • Typical Duration: 3 to 10 days for most acute admissions, with discharge typically occurring as soon as the immediate safety concern is resolved and a lower level of care can be arranged.
  • Primary Limitation: The ‘bubble effect.’ The controlled, highly structured inpatient environment can produce apparent stabilization that collapses immediately upon re-entry to the patient’s real-world environment. Inpatient care does not teach the distress tolerance and coping skills needed to sustain stability in community life — that work requires PHP or IOP.

CRITICAL NOTE ON INPATIENT MISUTILIZATION
A significant body of research — including studies published in Psychiatric Services and the Journal of Psychiatric Practice — identifies inpatient hospitalization as frequently overutilized for individuals who could have been safely and more effectively treated at the PHP level. The primary driver of this misutilization is the absence of accessible, high-quality PHP programs in many communities. At Balance Mental Health Group, our goal is to be the North Shore’s answer to this access gap.

The Master Comparison: All Four Levels Side by Side

The table below synthesizes the clinical, operational, financial, and structural dimensions of all four levels of care into a single reference framework. Columns marked PHP are highlighted because this is where Balance Mental Health Group operates and where most families navigating this guide will find the closest match to their current clinical situation.

Level of Care Profile Cards: Who Each Program Is Designed For

Clinical labels like ‘IOP’ and ‘PHP’ can obscure the human reality of who actually benefits from each level of care. The following profile cards translate the clinical criteria into concrete, recognizable descriptions of the individuals each program is designed to serve.

Traditional Outpatient

The maintenance patient

  • Manages daily responsibilities independently
  • Experiences mild to moderate symptoms that are not acutely worsening
  • Has established coping skills and a functional support network
  • Benefits from structured reflection and skill reinforcement
  • Has been stable on a consistent medication regimen for 6+ months
  • Sees therapy as proactive maintenance, not crisis management

Intensive Outpatient (IOP)

The step-down or partial-impairment patient

  • Recently discharged from PHP or inpatient and needs continued structure
  • Experiencing symptom flare that outpaces weekly therapy but retains daily function
  • Can work or attend school part-time alongside the program
  • Has a reliable support system at home
  • Needs group skills training and increased clinical touchpoints
  • Medication regimen is reasonably stable but requires monitoring

Partial Hospitalization (PHP)

The acutely destabilized patient

  • Cannot reliably attend work or school due to active symptoms
  • Requires daily psychiatric monitoring for medication adjustment
  • Experiencing severe functional impairment in 2+ life domains
  • Symptoms are acutely worsening and weekly therapy is insufficient
  • Has a safe home environment and no active, unmanageable safety risk
  • Needs structured full-day programming to prevent further deterioration

Inpatient Hospitalization

The acute safety crisis patient

  • Active suicidal ideation with a plan and means, or recent attempt
  • Active homicidal ideation or credible threat to a specific person
  • Severe psychiatric symptoms with complete loss of reality testing
  • Medical psychiatric emergency requiring 24-hour nursing oversight
  • Cannot be safely managed in any community-based setting
  • Requires physical containment to prevent immediate harm

PHP vs. IOP: The Distinction That Matters Most for Most Families

For the majority of individuals and families navigating this decision, the operationally relevant question is not ‘Do I need PHP or inpatient?’ — that determination is usually made in an emergency context with clinical support. The more commonly agonized question is the one that sits between PHP and IOP, because both programs appear superficially similar: both are community-based, both involve group therapy, both allow patients to live at home. The differences, however, are clinically profound and directly predictive of treatment outcomes.

The Psychiatric Element

The most clinically significant difference between PHP and IOP is the frequency and depth of psychiatric involvement. In an IOP, medication evaluation occurs on a weekly or biweekly basis — sufficient for patients whose medication regimens are stable and whose primary need is structured skill-building and social support. In a PHP, psychiatric evaluation is a daily event. The PMHNP or psychiatrist reviews each patient’s presentation every morning, monitors medication response and side effects in real time, and can make medication adjustments within hours rather than weeks.

For patients experiencing diagnostic instability — where mood symptoms, psychotic features, or trauma responses are shifting rapidly — this difference is not administrative. It is the difference between a medication that is causing worsening depression going undetected for two weeks versus being identified and adjusted within 48 hours.

Clinical Example
A patient presenting with what appears to be a Major Depressive Episode begins a new antidepressant in an IOP. Over the following week, they develop emerging hypomanic symptoms — increased energy, decreased sleep, and elevated mood — suggesting the diagnosis may actually be Bipolar Disorder. In an IOP, this shift might not be clinically recognized until the weekly medication appointment. In a PHP, the daily psychiatric check-in would identify this emerging pattern within 24 to 48 hours, allowing rapid diagnostic recalibration and a medication adjustment that prevents the hypomanic episode from fully developing.

Clinical Hours and Therapeutic Density

IOP provides 9 to 15 hours of clinical contact per week. PHP provides 20 to 30 hours. This is not merely a quantitative difference. The therapeutic density of a PHP — the concentration of clinical modalities, peer interaction, and skills practice within a structured therapeutic environment — creates a qualitatively different treatment experience. Research published by the American Psychiatric Association (https://www.psychiatry.org) consistently demonstrates that patients with acute functional impairment require sustained, high-intensity clinical exposure to achieve meaningful symptom reduction on validated outcome measures such as the PHQ-9, GAD-7, and Columbia Suicide Severity Rating Scale.

Put differently: for a patient who is spending 20+ hours per week in clinically unsupported distress, an IOP’s 12 hours of clinical contact leaves a substantial portion of the week in therapeutic absence. A PHP’s 30 hours provides consistent containment and skill activation that narrows that window significantly.

The Real-World Integration Loop

Perhaps the most clinically distinctive and evidence-supported feature of PHP over both IOP and inpatient care is what our clinical team refers to as the real-world integration loop. Every PHP patient learns skills in the morning, applies them in their actual home environment in the evening, and returns to the program the following morning for clinical analysis of how that application went.

This feedback architecture accelerates skill transfer in ways that neither a hospital (too isolated from real-world triggers) nor an IOP (too infrequent clinical contact to debrief in near-real-time) can replicate. The patient who has a conflict with their spouse at 8:00 PM on a Tuesday can work through the entire interaction — the trigger, the cognitive distortion, the maladaptive response, and a revised coping strategy — with their clinical team at 9:30 AM on Wednesday. This cycle produces sustainable, generalized skill acquisition rather than isolated clinical progress.

When IOP Is the Right Choice

IOP is not a compromise or a lesser option — it is the clinically appropriate choice for a specific and important patient population. IOP is the right level of care when:

  • Step-down from PHP or inpatient: The patient has achieved acute stabilization and needs continued structured support to consolidate gains before returning to independent outpatient care.
  • Partial functional impairment: The patient is experiencing elevated symptoms and increased distress but retains sufficient daily functioning to manage a part-time clinical schedule alongside work, school, or family responsibilities.
  • Medication stability: The patient’s psychiatric medication regimen is reasonably established and does not require daily oversight.
  • Strong community support: The patient has a robust, supportive home environment that provides meaningful clinical buffering during the hours outside the program.
  • Prevention over crisis: The patient and their outpatient provider are proactively increasing clinical intensity to prevent escalation rather than responding to an active crisis.

PHP vs. Inpatient: Why Day Treatment Is Often the Better Path

The default instinct for many families facing a loved one’s acute mental health crisis is to seek the most intensive available care — and in a medical emergency context, that instinct is appropriate. A broken leg warrants an emergency room. A heart attack warrants an ICU. But the behavioral healthcare evidence base has established conclusively that acute psychiatric crises, in the majority of cases, are not best served by the most intensive possible environment.

IF YOU ARE IN CRISIS RIGHT NOW

If you or a loved one is experiencing an acute safety crisis — suicidal ideation with a plan, an active attempt, or a psychiatric emergency — do not use this guide to make a level-of-care decision. Call 911 or go to your nearest emergency room immediately.

For a mental health crisis that does not involve immediate danger: Call or text 988 (Suicide and Crisis Lifeline, available 24/7). Text HOME to 741741 (Crisis Text Line). Call the Massachusetts Behavioral Health Helpline: 1-800-327-5050.

Once the immediate crisis is stabilized, contact Balance Mental Health Group at (978) 326-9055 to discuss whether PHP is the appropriate next step.

The Secondary Trauma Problem

Inpatient psychiatric units are designed for a single purpose: rapid safety stabilization. The physical and operational requirements of that purpose — locked wards, restrictive access to personal items, limited privacy, co-mingling of patients at vastly different levels of acuity — create an environment that, for many individuals (particularly those with trauma histories, younger adults, or individuals with high anxiety sensitivity), is itself a source of clinical distress.

Research published in the Journal of Traumatic Stress and reviewed by SAMHSA’s Trauma-Informed Care initiative (https://www.samhsa.gov/trauma-violence) has identified what clinicians call secondary institutionalization trauma — the distress response generated not by the original psychiatric condition but by the experience of psychiatric hospitalization itself. This trauma does not diminish the value of inpatient care when it is genuinely indicated. It does, however, make a compelling case for accessing PHP — where the therapeutic environment is open, welcoming, and embedded in the community — whenever it is clinically safe to do so.

The Continuity Advantage

One of the most consistently documented outcomes advantages of PHP over inpatient care involves the continuity of the therapeutic relationship. When a patient enters an inpatient unit, they are assigned to whichever treatment team is on rotation. The relationship is, by structural necessity, brief and transactional. The therapeutic alliance — which decades of psychotherapy research identify as one of the strongest predictors of treatment outcome (see the American Psychological Association’s research summary at https://www.apa.org) — cannot develop meaningfully in a 3 to 7 day hospitalization.

In a PHP, the patient is assigned a consistent primary clinician for the entirety of their admission — whether that admission lasts two weeks or two months. The therapeutic relationship deepens over time, enabling increasingly precise, personalized clinical intervention. The clinician who sees a patient on day two of their PHP admission knows that patient’s history, their family dynamics, their medication sensitivities, and their characteristic maladaptive patterns. By week three, that clinical knowledge enables a level of intervention precision that inpatient care structurally cannot provide.

Appropriate Indications for Inpatient — When PHP Is Not Enough

Clarity about PHP’s advantages should not create a false impression that inpatient hospitalization is never the right choice. There are specific clinical situations in which inpatient care is the only appropriate intervention, and recognizing these situations is itself a critical clinical skill for families and providers:

  • Active suicidal ideation with a plan and means: When an individual has identified a specific method, has access to that method, and the risk is imminent, community-based care is not sufficient. Inpatient provides the physical safety containment that this clinical situation requires.
  • Recent suicide attempt: A patient presenting following an attempt requires immediate medical evaluation and a period of intensive psychiatric monitoring that only an inpatient setting can provide.
  • Active psychosis with complete loss of reality testing: When a patient is experiencing command hallucinations, severe paranoid delusions that are driving dangerous behavior, or a complete inability to care for their basic physical needs, the safety and medical requirements exceed PHP’s scope.
  • Medical psychiatric emergency: Neuroleptic malignant syndrome, serotonin syndrome, severe medication toxicity, or psychiatric symptoms secondary to a medical condition requiring nursing-level medical oversight.
  • Severe eating disorder with medical instability: When malnutrition has progressed to the point of cardiac arrhythmia, electrolyte imbalance, or vital sign instability, inpatient medical care is required before behavioral health treatment can safely proceed.

The Clinical Decision Tool: Which Level of Care Matches Your Situation?

The table below is a clinical decision reference — not a diagnostic tool. No table can substitute for a formal clinical assessment conducted by a licensed behavioral health professional. However, this framework can help you and your family begin to identify the level of care that is likely to be most appropriate for your current situation, and give you a concrete starting point for your conversation with a clinical intake team.

If your situation looks like this... Consider this level of care
You have a weekly therapist and your symptoms are stable but you want maintenance support Traditional Outpatient
You recently stepped down from PHP or inpatient and need structured support to stay stable IOP (Intensive Outpatient)
You cannot reliably attend work or school due to active psychiatric symptoms PHP (Day Treatment) ★
You have daily medication instability or require frequent psychiatric adjustments PHP (Day Treatment) ★
Your existing therapist or outpatient provider says weekly sessions are no longer sufficient PHP or IOP — Contact us for assessment
You are experiencing acute suicidal ideation with a plan, or are a danger to others Inpatient Hospitalization — Call 988 or 911
You need medical detox or have a co-occurring substance use disorder requiring 24-hour monitoring Inpatient or Residential — Refer to SAMHSA
You have completed inpatient and are ready to transition back to community-based care PHP then IOP Step-Down
You are a young adult (18–26) experiencing identity, academic, or social-related crisis PHP Young Adult Track
Your symptoms are manageable but a major life stressor is pushing you toward crisis IOP or PHP Assessment

Navigating Transitions Between Levels of Care

The behavioral healthcare continuum is not a one-directional escalator. Clinical needs change over time — sometimes worsening, sometimes improving — and effective treatment requires the flexibility to move both up and down the continuum as the clinical picture evolves. Understanding how these transitions work prevents the most common navigational errors families make.

Balance Mental Health Addiction Treatement MA 68 scaled
The Standard Step-Down Pathway

For the majority of individuals who access PHP care at Balance Mental Health Group, the clinical trajectory follows a predictable arc: acute stabilization in PHP (typically 2–4 weeks), followed by a step-down to IOP (typically 4–8 weeks), followed by a return to traditional outpatient care with an established outpatient therapist and prescriber. This stepped-down transition is not arbitrary — it mirrors the progressive return of autonomous coping capacity that effective PHP treatment produces.

The discharge from PHP to IOP is a clinical determination made jointly by the treatment team and, in collaboration, the patient’s insurance carrier. Clinical indicators for step-down include: consistent daily functioning across the primary life domains, stable medication response with no daily adjustment requirements, adequate distress tolerance skill acquisition as evidenced by real-world application, and a sufficiently safe and supportive home environment to manage the reduced clinical contact of IOP.

For a detailed guide to this transition, see: Stepping Down from PHP to IOP: What Happens After Day Treatment?.

When Inpatient Follows PHP: What to Expect

In a minority of cases, a patient admitted to PHP will experience clinical deterioration during the course of treatment that requires escalation to inpatient care. This is not a treatment failure. It is the clinical safety net functioning as intended. PHP’s daily psychiatric monitoring is precisely designed to detect this kind of deterioration early — which is why PHP patients who ultimately require inpatient care typically arrive in a far less acute state than patients who deteriorate from outpatient care without daily monitoring.

If inpatient admission occurs during a PHP episode, our case management team provides direct, coordinated communication with the receiving inpatient facility, shares clinical documentation to prevent redundant assessments, and maintains the therapeutic relationship so that re-admission to PHP following discharge is smooth and clinically continuous.

Re-entry from Inpatient to PHP

For individuals discharging from inpatient psychiatric hospitalization, PHP represents the evidence-based standard of care for the post-acute transition period. The research literature — including the APA’s practice guidelines for major depressive disorder, bipolar disorder, and schizophrenia spectrum conditions — consistently identifies early, intensive step-down care as the single most important predictor of 30-day and 90-day post-discharge outcomes.

Balance Mental Health Group maintains an expedited intake pathway for individuals discharging from inpatient settings. If you or a loved one is currently hospitalized and approaching discharge, our clinical intake team can initiate a pre-discharge assessment and have a placement determination and insurance authorization ready within 24 to 48 hours of the anticipated discharge date.

Insurance and Financial Navigation Across Levels of Care

Each level of the behavioral healthcare continuum is classified differently by commercial insurers, and understanding these classifications helps families anticipate both the authorization process and their likely cost exposure.

How Insurance Classifies Each Level

  • Traditional Outpatient: Covered under the standard mental health outpatient benefit. Subject to the plan’s standard copay or coinsurance. Typically no prior authorization required for initial visits.
  • Intensive Outpatient (IOP): Classified as an intensive outpatient mental health service. Prior authorization required by most carriers. Subject to the plan’s outpatient benefit with higher clinical thresholds.
  • Partial Hospitalization (PHP): Classified as a distinct PHP or Day Treatment benefit — separate from both outpatient and inpatient benefits. Prior authorization required. Clinical documentation of medical necessity must be renewed on a concurrent basis during admission.
  • Inpatient Hospitalization: Covered under the inpatient mental health benefit, subject to the plan’s inpatient deductible and coinsurance structure. Prior authorization required and retrospective reviews are common.

The Mental Health Parity Imperative

Under the federal Mental Health Parity and Addiction Equity Act (MHPAEA) and its Massachusetts state equivalent, insurers are legally required to cover mental health and substance use disorder benefits at parity with comparable medical/surgical benefits. This means an insurer cannot impose more restrictive prior authorization requirements, higher cost-sharing, or stricter medical necessity standards for behavioral health services than it applies to analogous medical services. If you believe your insurer is applying non-parity standards to your PHP claim, the Massachusetts Division of Insurance provides a formal complaint and review process.

Psychiatric Evening Treatment Program Balance Mental Health Group2

PHP Clinical Outcomes

Meta-analytic reviews of PHP outcomes — including a landmark analysis published in the Journal of Psychiatric Practice examining data from over 10,000 PHP admissions — have consistently demonstrated that PHP produces equivalent or superior outcomes to inpatient hospitalization for appropriate patient populations across three primary outcome domains: symptom severity reduction (PHQ-9, GAD-7, PCL-5), functional restoration (Global Assessment of Functioning), and post-treatment stability (readmission rates at 30, 90, and 180 days).

Critically, PHP produces these outcomes at substantially lower cost, with dramatically less disruption to daily life, and with significantly lower rates of secondary institutionalization trauma. The American Association for Emergency Psychiatry (https://www.emergencypsychiatry.org) and the APA’s Emergency Psychiatry Task Force have both endorsed PHP as the preferred post-acute transition level of care for appropriate patients.

The ‘Step-Down’ Research

Perhaps the most compelling research argument for PHP involves the post-inpatient step-down literature. Studies examining 30-day readmission rates following inpatient psychiatric discharge consistently find that patients who step down to PHP immediately following discharge have readmission rates 40 to 60 percent lower than patients who step down directly to IOP or traditional outpatient care. This finding has been replicated across multiple patient populations, diagnostic categories, and geographic regions, and forms the basis for the APA’s clinical practice guidelines recommending PHP as the default post-acute step-down level of care.

What Research Says About Avoiding Inpatient

A 2019 study published in Psychiatric Services examined outcomes for patients presenting to emergency psychiatric services who were randomized to either inpatient admission or immediate PHP placement. Patients with equivalent clinical severity at presentation who were placed in PHP showed equivalent 90-day symptom outcomes, higher rates of employment retention, higher rates of therapeutic alliance maintenance, and significantly lower rates of post-treatment service avoidance (i.e., they were more likely to continue engaging with the mental health system long-term). The authors concluded that PHP-first placement for clinically appropriate patients should be the standard of care in emergency psychiatric diversion protocols.
