Inpatient Psychiatric Care Outcomes for Adolescents: A Test of Clinical and Psychosocial Moderators

A Quality Improvement Initiative to Decrease Behavioral Health Unit Readmission Rates

OBJECTIVE

Youth behavioral health inpatient beds are limited during a time of crisis. Around one-third of youth admitted to a behavioral health unit (BHU) will be readmitted within 1 year of discharge, with 8% to 13% being admitted within 30 days. In one study, they found that more than one-third of patients initially admitted for suicidal ideation or attempt were readmitted within 7 days. Our objective was to decrease 7-day and 30-day readmission rates to our BHU by 20% by May of 2023.

METHODS

We collected baseline data through medical record review for our pediatric BHU readmissions from July 2020 until July 2021. Interventions, such as standardized workflows and checklists, were trialed with Plan-Do-Study-Act (PDSA) cycles beginning October 2021 until November 2022. Performance was analyzed using statistical process control charts (U-charts). Sustainment was tracked through December 2023. Length of stay (LOS) was tracked as a balancing measure. Compliance with our readmission checklist was tracked as a process measure.

RESULTS

Both 7-day and 30-day readmission rates to the pediatric BHU decreased as interventions were initiated and adopted. The rates of patients readmitted within 7 and 30 days decreased from a baseline mean of 5.54 to 2.83 (49%) and 11.52 to 7.38 (36%) per 100 hospitalizations, respectively. The LOS for the BHU decreased from 5.58 to 5.09 days. The readmission checklist was used for 81 out of 83 patients, or 97.5%.

CONCLUSION

Adoption of multiple interventions produced a decrease in readmissions to a pediatric BHU.

Predicting the trajectory of non-suicidal self-injury among adolescents

BACKGROUND

Non-suicidal self-injury (NSSI) is common among adolescents receiving inpatient psychiatric treatment and the months post-discharge is a high-risk period for self-injurious behavior. Thus, identifying predictors that shape the course of post-discharge NSSI may provide insights into ways to improve clinical outcomes. Accordingly, we used machine learning to identify the strongest predictors of NSSI trajectories drawn from a comprehensive clinical assessment.

METHODS

The study included adolescents (N = 612; females n = 435; 71.1%) aged 13-19-years-old (M = 15.6, SD = 1.4) undergoing inpatient treatment. Youth were administered clinical interviews and symptom questionnaires at intake (baseline) and before termination. NSSI frequency was assessed at 1-, 3-, and 6-month follow-ups. Latent class growth analyses were used to group adolescents based on their pattern of NSSI across follow-ups.

RESULTS

Three classes were identified: Low Stable (n = 83), Moderate Fluctuating (n = 260), and High Persistent (n = 269). Important predictors of the High Persistent class in our regularized regression models (LASSO) included baseline psychiatric symptoms and comorbidity, past-week suicidal ideation (SI) severity, lifetime average and worst-point SI intensity, and NSSI in the past 30 days (bs = 0.75-2.33). Only worst-point lifetime suicide ideation intensity was identified as a predictor of the Low Stable class (b = -8.82); no predictors of the Moderate Fluctuating class emerged.

CONCLUSIONS

This study found a set of intake clinical variables that indicate which adolescents may experience persistent NSSI post-discharge. Accordingly, this may help identify youth that may benefit from additional monitoring and support post-hospitalization.

Reducing Pediatric Mental Health Boarding and Increasing Acute Care Access

BACKGROUND

There have been notable increases in pediatric mental health boarding in the United States in recent years, with youth remaining in emergency departments or admitted to inpatient medical/surgical units, awaiting placement in psychiatric treatment programs.

OBJECTIVES

We aimed to evaluate the outcomes of interventions to reduce boarding and improve access to acute psychiatric services at a large tertiary pediatric hospital during a national pediatric mental health crisis.

METHODS

Boarding interventions included expanding inpatient psychiatric beds and hiring additional staff for enhanced crisis stabilization services and treatment initiation in the emergency department and on inpatient medical/surgical units for boarding patients awaiting placement. Post-hoc assessment was conducted via retrospective review of patients presenting with mental health emergencies during the beginning of intervention implementation in October-December 2021 and one year later (October-December 2022). Inclusion criteria were patients ≤17 years who presented with mental health-related emergencies during the study period. Exclusion criteria were patients ≥18 years and/or patients with >100 days of admission awaiting long-term placement. Primary outcome was mean length of boarding (LOB). Secondary outcome was mean length of stay (LOS) at the hospital's acute psychiatry units.

RESULTS

One year after full intervention implementation (October-December 2022), mean LOB decreased by 53% (4.3 vs 9.1 days, P < 0.0001) for boarding patients discharged to high (e.g., inpatient, acute residential) and intermediate (e.g., partial hospital, in-home crisis stabilization programs) levels of care, compared to October-December 2021. Additionally, mean LOS at all the 24-hour acute psychiatry treatment programs was reduced by 27% (20.0 vs 14.6 days, P = 0.0002), and more patients were able to access such programs (265/54.2% vs 221/41.9%, P < 0.0001). Across both years, youth with aggressive behaviors had 193% longer LOB (2.93 ± 1.15, 95% CI [2.23, 3.87]) than those without aggression, and youth with previous psychiatric admissions had 88% longer LOB than those without (1.88 ± 1.11, 95% CI [1.54, 2.30]).

CONCLUSIONS

The current study shows decreased LOB and improved access for youth requiring acute psychiatric treatment after comprehensive interventions and highlights challenges with placement for youth with aggressive behaviors. We recommend a call-to-action for pediatric hospitals to commit sufficient investment in acute psychiatric resources to address pediatric mental health boarding.

Stress exposure in at-risk, depressed, and suicidal adolescents

BACKGROUND

Stress exposure contributes to the onset, maintenance, and recurrence of major depressive disorder (MDD) in adolescents. However, the precise stress facets (e.g. chronicity, domain) most strongly linked to outcomes at different stages along the depression severity continuum remain unclear. Across two studies, chronic and episodic stressors were comprehensively assessed among: (a) healthy youth with (High-Risk [HR]) and without (Low-Risk [LR]) a maternal history of MDD and (b) adolescents with current MDD and suicide ideation and healthy controls (HC).

METHOD

Study 1 included LR (n = 65) and HR (n = 22) 12- to 14-year-olds (49 females; 56.32%) with no lifetime history of mental disorders. Study 2 enrolled 87 mid-to-late adolescents (64 females; 73.56%), including 57 MDD youth from a short-term intensive treatment service and 30 HCs from the community. All depressed youth reported recent suicide ideation; some had no lifetime history suicide attempts (SI; n = 31) and others reported at least one past year attempt (SA; n = 26). The Life Events and Difficulties Schedule was used to capture stressor severity in both studies.

RESULTS

We used multiple linear regression models that adjusted for demographic and clinical covariates. Being in the HR versus LR group was associated with more severe chronic (β = .22, CI95 = 0.01-0.42, p = .041), independent (β = .34, CI95 = 0.12-0.56, p = .003), and interpersonal (β = .23, CI95 = 0.004-0.45, p = .047) stress severity. By contrast, the MDD group reported significantly more severe chronic (β = .62, CI95 = 0.45-0.79, p < .001) and dependent (β = .41, CI95 = 0.21-0.61, p < .001) stress than the HC group, but not independent (p = .083) stress. Stress severity did not differ between recent attempters versus youth who reported suicide ideation alone (SA vs. SI contrast). However, the SA group reported a higher rate of targeted rejection events (RR = 3.53, CI95 = 1.17-10.70, p = .026).

CONCLUSIONS

Our findings clarify the stressor features that may most strongly contribute to adolescent depression and its clinical correlates at two important points along depression's clinical course.

Non-suicidal Self-injurious Thoughts and Behaviors Among Adolescent Inpatients

Non-suicidal self-injury (NSSI) is a serious public health concern that typically onsets during early adolescence. Adolescents (N = 980, ages 12-19 years) admitted for acute, residential psychiatric treatment completed baseline clinical interviews assessing mental disorders and questionnaires measuring demographics, early life adversity, and symptom severity. Prevalence rates of NSSI for lifetime (thoughts: 78%; behaviors: 72%), past year (thoughts: 74%; behaviors: 65%), and past month (thoughts: 68%; behaviors: 51%) were high. Although effect sizes were modest, the presence of a lifetime depressive disorder, sexual abuse, and comorbidity (i.e., three or more current disorders) were significant correlates of experiencing NSSI thoughts and behaviors. Furthermore, lifetime depressive disorder, current anxiety disorder, and comorbidity were associated with a greater odds of persistent NSSI thoughts and/or behaviors. Longitudinal studies are needed to determine whether targeting these factors reduces the persistence of NSSI thoughts and behaviors.

Psychiatric Boarding Patterns Among Publicly Insured Youths Evaluated by Mobile Crisis Teams Before and During the COVID-19 Pandemic

Importance

Psychiatric boarding occurs when patients needing intensive psychiatric services who are already under clinical supervision experience delays in their admission to psychiatric facilities. Initial reports have suggested that the US had a psychiatric boarding crisis during the COVID-19 pandemic; however, little is known about the consequences of this crisis for publicly insured youths.

Objective

To estimate pandemic-associated changes in psychiatric boarding rates and discharge modalities for people aged 4 to 20 years who accessed psychiatric emergency services (PES) through a mobile crisis team (MCT) evaluation and were covered by Medicaid or health safety net programs.

Design, Setting, and Participants

This retrospective cross-sectional study used data from the MCT encounters of a multichannel PES program in Massachusetts. A total of 7625 MCT-initiated PES encounters with publicly insured youths who lived in Massachusetts between January 1, 2018, and August 31, 2021, were assessed.

Main Outcomes and Measures

Encounter-level outcomes (psychiatric boarding status, repeat visits, and discharge disposition) during a prepandemic period (January 1, 2018, to March 9, 2020) were compared with outcomes during a pandemic period (March 10, 2020, to August 31, 2021). Descriptive statistics and multivariate regression analysis were used.

Results

Among 7625 MCT-initiated PES encounters, the mean (SD) age of publicly insured youths was 13.6 (3.7) years; most youths identified as male (3656 [47.9%]), were of Black race (2725 [35.7%]) or Hispanic ethnicity (2708 [35.5%]), and spoke English (6941 [91.0%]). During the pandemic period, the mean monthly boarding encounter rate was 25.3 percentage points higher than the prepandemic period. After adjustment for covariates, the odds of an encounter resulting in boarding doubled during the pandemic (adjusted odds ratio [AOR], 2.03; 95% CI, 1.82-2.26; P < .001), and boarding youths were 64% less likely to be discharged to inpatient psychiatric care (AOR, 0.36; 95% CI, 0.31-0.43; P < .001). Publicly insured youths who boarded during the pandemic had significantly higher rates of 30-day readmissions (incidence rate ratio, 2.17; 95% CI, 1.88-2.50; P < .001). Boarding encounters during the pandemic were significantly less likely to end in discharge to inpatient psychiatric units (AOR, 0.36; 95% CI, 0.31-0.43; P < .001) or community-based acute treatment facilities (AOR, 0.70; 95% CI, 0.55-0.90; P = .005).

Conclusions and Relevance

In this cross-sectional study, publicly insured youths were more likely to experience psychiatric boarding during the COVID-19 pandemic and, if boarding, were less likely to transfer to a 24-hour level of care. These findings suggest that psychiatric service programs for youths were not prepared to support the levels of acuity and demand that emerged from the pandemic.

Suicidal Thoughts and Behaviors Among Adolescent Psychiatric Inpatients

BACKGROUND

Given low base rates of suicidal thoughts and behaviors (STBs) in national samples of adolescents, clarifying the sociodemographic and clinical correlates among psychiatric inpatients may afford insights into potential risk factors that predict STBs onset.

METHOD

Adolescents (N = 970; ages 12-19 years) admitted for acute, psychiatric inpatient care completed baseline clinical interviews and self-report measures assessing demographics and early life adversity. Lifetime and 12-month STBs prevalence were obtained, allowing for the estimate of STBs persistence (i.e., rates of those with both current and past STBs) and transition rates (i.e., proportion of ideators that transition to plans or attempts). Univariate and multivariate logistic regression tested sociodemographic and clinical correlates of STBs.

RESULTS

Age-of-onset for STBs occurred in early adolescence. Most patients reported suicide ideation with nearly half of patients making a plan and one-third a suicide attempt. Although relatively modest, the strongest correlates of lifetime attempts were depressive disorders, physical abuse, and non-suicidal self-injury. Knowing a peer that had attempted suicide also increased the likelihood of a suicide attempt, especially among attempters who transitioned from ideation to planned attempts.

CONCLUSION

STBs are highly prevalent among adolescents admitted for acute psychiatric inpatient treatment. The modest effects suggest that correlates, particularly those related to suicide attempts, are widely distributed. As a history of physical abuse and knowing a peer with a suicide attempt history are related to transitioning from ideation to action, these may be critical factors to target in the deployment of future suicide prevention and treatment programs. HIGHLIGHTSOne-third of adolescent inpatients report a lifetime history of suicide attempts.Approximately 65% of adolescent inpatients with a lifetime plan attempt suicide.Knowing peers who attempt suicide may facilitate the transition from ideation to action.

Looking for the Good Timing: Predictors of Length of Stay and Therapeutic Outcomes in Adolescent Inpatients with Severe or Treatment-Refractory Mood Disorders

Objectives: While hospitalization is an essential aspect of the therapeutic strategy for adolescents with severe or treatment-refractory mood disorders, little is known about the outcome predictors during inpatient treatment. Methods: A retrospective chart review was conducted in a university tertiary referral hospital to determine the factors associated with the length of stay, symptom improvement (based on the Clinical Global Impression-Improvement [CGI-I] scale), and the change in the overall level of functioning during the stay (based on the Children-Global Assessment Scale [CGAS]). Over 2 years, 106 adolescents were diagnosed with mood disorders (mean age = 15.0 ± 0.16; 43% girls), with a particular high rate of associated adverse psychosocial factors, and an average length of stay longer than most psychiatric hospital settings (mean = 100.7 ± 9.57 days). Results: Multivariate analysis concluded that longer duration of current episode and worse functioning at admission (CGAS score) were independent predictors for length of stay. Greater functional improvement (CGAS score change from admission to discharge) was best predicted by the diagnosis of bipolar disorder, lower functioning, and greater illness severity on admission. Symptom improvement (CGI-I) did not have any independent predictors. Conclusion: This finding supports the value of measuring symptoms duration in predicting the hospitalization outcomes of adolescents with severe or treatment-refractory mood disorders, in view of addressing maintenance factors at an early stage. Bipolar symptoms should be sought not only at admission but also regularly during the stay.
