The Impact of Integrated Psychiatric Care on Hospital Medicine Length of Stay: A Pre-Post Intervention Design With a Simultaneous Usual Care Comparison

Impact of Preexisting Depression and Anxiety on Hospital Readmission and Long-Term Survival After Cardiac Arrest

BACKGROUND

While sudden cardiac arrest (CA) survivors are at risk for developing psychiatric disorders, little is known about the impact of preexisting mental health conditions on long-term survival or postacute healthcare utilization. We examined the prevalence of preexisting psychiatric conditions in CA patients who survived hospital discharge, characterized incidence and reason for inpatient psychiatry consultation during these patients' acute hospitalizations, and determined the association of pre-CA depression and anxiety with hospital readmission rates and long-term survival. We hypothesized that prior depression or anxiety would be associated with higher hospital readmission rates and lower long-term survival.

METHODS

We conducted a retrospective cohort study including patients resuscitated from in- and out-of-hospital CA who survived both admission and discharge from a single hospital between January 1, 2010, and December 31, 2017. We identified patients from our prospective registry, then performed a structured chart review to abstract past psychiatric history, prescription medications for psychiatric conditions, and identify inpatient psychiatric consultations. We used administrative data to identify readmissions within 1 year and vital status through December 31, 2020. We used multivariable Cox regressions controlling for patient demographics, medical comorbidities, discharge Cerebral Performance Category and disposition, depression, and anxiety history to predict long-term survival and hospital readmission.

RESULTS

We included 684 subjects. Past depression or anxiety was noted in 24% (n = 162) and 19% (n = 129) of subjects. A minority of subjects (n = 139, 20%) received a psychiatry consultation during the index hospitalization. Overall, 262 (39%) subjects had at least 1 readmission within 1 year. Past depression was associated with an increased hazard of hospital readmission (hazard ratio 1.50, 95% CI 1.11-2.04), while past anxiety was not associated with readmission. Neither depression nor anxiety were independently associated with long-term survival.

CONCLUSIONS

Depression is an independent risk factor for hospital readmission in CA survivors.

Patient and Medical Unit Staff Experiences of Proactive and Integrated Consultation-Liaison Psychiatry in The HOME Study: A Qualitative Investigation

BACKGROUND

Consultation-liaison (C-L) psychiatry services aim to help general hospital staff provide better care for their patients. Recently, many inpatient C-L psychiatry services have adopted proactive and integrated approaches to achieve this aim. Despite these developments, there have been no interview-based studies of patients' and staff members' experiences of the new approaches.

OBJECTIVE

To gain an in-depth understanding of patients' and medical unit staff members' experiences of a proactive and integrated C-L psychiatry service for older medical inpatients (Proactive Integrated C-L Psychiatry [PICLP]).

METHODS

We conducted an interview-based qualitative study with thematic analysis. The participants were patients and staff who had experienced PICLP during The HOME Study, a randomized trial that evaluated PICLP in 24 medical units of three UK general hospitals.

RESULTS

We conducted 97 interviews: 43 with patients or their proxies (family members who were interviewed on behalf of patients with significant cognitive impairment) and 54 with staff members of all relevant disciplines. Patients and staff both described how PICLP was a helpful addition to medical care and discharge planning. It enhanced the medical unit team's ability to address psychological, psychiatric, and social needs and provide patient-centered care. They welcomed proactive biopsychosocial assessments and the broader perspective that these offered on patients' complex problems. They also valued the integration of C-L psychiatrists into the unit teams and their daily contact with them. For patients, it fostered a therapeutic relationship and helped them to be more engaged in decisions about their medical care and discharge planning. For staff, it enabled ready access to psychiatric expertise and training opportunities. The few reported experiences of PICLP being unhelpful were mainly about the greater number of clinicians involved in patients' care and a lack of clarity about professional roles in the integrated team.

CONCLUSIONS

We found that older inpatients and medical unit staff experienced PICLP as both acceptable and generally helpful. Our findings add to the existing evidence for the benefits of proactive and integrated C-L psychiatry services.

Psychiatric Consults Associated With Longer Length of Stay in Trauma Patients-A Retrospective Study

INTRODUCTION

Mental illness is a risk factor for intentional and unintentional injury and is associated with readmission. The impact of psychiatric consults on length of stay (LOS) of trauma patients is still undergoing study.

METHODS

Trauma registry at Ascension St. Mary's of Saginaw, a community level 2 trauma center, was queried. Further chart review was performed to demographically characterize the control and intervention groups. Univariate and multivariate regression was performed to identify the association between psychiatric consultation and LOS while considering demographic variables and Injury Severity Score.

RESULTS

A total of 661 patients were identified with trauma and a documented mental health disorder. 612 did not receive a psychiatric consultation and 49 did. The group without a psychiatric consultation had a mean and median LOS of 6 d and 4 d, respectively, compared to 12 d and 10 d for those with a psychiatric consult (P < 0.0001). Mean ISS scores comparable across all groups. Delirium was associated with the highest LOS with a mean of 17.25 d and a median of 14.5 d. All 11 patients transferred to a psychiatric facility at discharge received a consult for self-harm.

CONCLUSIONS

Psychiatric consultations were associated with lengthened stay of trauma patients independent of initial injury severity and documented mental health disorders, and more transfers to inpatient psych facilities. This represents an important prognostic factor for a patient's course of care and suggests that trauma physicians should be well-versed at identifying mental health issues which may require early intervention, as well as managing delirium.

The impact of rounds with a psychiatry team in the intensive care unit: A prospective observational pilot study evaluating the effects on delirium incidence and outcomes

BACKGROUND

Delirium in the intensive care unit (ICU) is a common but serious condition that has been associated with in-hospital mortality and post-discharge psychological dysfunction. The aim of this before and after study is to determine the effect of a multidisciplinary care model entailing daily ICU rounds with a psychiatrist on the incidence of delirium and clinical outcomes.

OBJECTIVE

To assess the impact of a proactive psychiatry consultation model in the surgical ICU on the incidence and duration of delirium.

METHODS

This was a prospective, single institution, observational controlled cohort pilot study of adult patients admitted to a surgical ICU. A control group that received standard of care (SOC) with daily delirium prevention care bundles in the pre-intervention period was compared to an intervention group, which had a psychiatrist participate in daily ICU rounds (post-intervention period). The primary outcome was delirium incidence. The secondary outcomes were: delirium duration, ventilator days, hospital and ICU length of stay, and in-hospital mortality.

RESULTS

A total of 104 patients were enrolled and equally split between SOC and intervention groups; 95 contributed to analysis. The overall incidence of ICU delirium was 19%. SOC and intervention groups had similar rates of delirium (21% vs 18%, p = 0.72). None of the secondary outcomes statistically significantly differed between the two groups.

CONCLUSION

Delirium in ICU patients is a potentially preventable condition with serious sequelae. There was no difference in delirium incidence or duration between patients receiving SOC or patients who had multidisciplinary rounds with a psychiatrist.

An Economic Evaluation of a Proactive Consultation-Liaison Psychiatry Pilot as Compared to Usual Psychiatric Consultation On-Demand for Hospital Medicine

BACKGROUND

A growing literature demonstrates the value of the Proactive Consultation-Liaison (C-L) Psychiatry model for healthcare systems through reductions in hospital length of stay (LOS). Few studies include financial outcomes. We evaluated the return on investment (ROI) of a one-year Proactive C-L Psychiatry pilot on a hospital medicine unit.

METHODS

We used a pre-post method with an active comparison of three hospital medicine units with regular psychiatric consultation on-demand. We staffed the Pilot unit with one full-time psychiatrist who focused on early case finding, close communication with unit staff, frequent follow-up visits, and proactive discharge planning. We assessed the one-year change in mean LOS for all patients receiving psychiatric consultation, from which we estimated the direct contribution margin (DCM) from bed backfills and the program's return on investment (ROI).

RESULTS

On the Pilot unit, the percent of discharges that received psychiatric consultation increased from 7.34% to 13.79%, and the LOS for patients consulted on declined by a mean of 1.82 days (P<0.05), as compared to an increase of 0.15 days (P>0.05) on the usual care units. The Pilot unit reduction in LOS saved 451.71 days total, allowing for 73.81 bed-backfills, a DCM of $419,343 (95% confidence interval, $50,754 to $787,933), a net DCM of $298,245 (-$70,344 to $666,835) and ROI of 132% (-31% to 295%).

CONCLUSION

This study strengthens existing evidence for the relative cost-effectiveness of Proactive Consultation-Liaison (C-L) Psychiatry for hospital medicine compared to usual psychiatric consultation on-demand.

Changes of consultation-liaison psychiatry practice in Italian general hospitals: A comparative 20-year multicenter study

INTRODUCTION

Conducted under the auspices of the Italian Society of Consultation Liaison Psychiatry (SIPC) the aim of this study was to describe the characteristics of Consultation Liaison Psychiatry (CLP) activity in Italy (SIPC-2-2018) over the past 20 years by comparing with data from the first Italian nation-wide study (SIPC-1-1998).

METHODS

We collected data on CLP visits of 3,943 patients from 10 Italian hospitals over a period of 1 year. Data were compared with those from the SIPC-1 1998 study (4,183 participants). Patients were assessed with the same ad hoc 60-item Patient Registration Form recording information from five different areas: Sociodemographic, hospitalization-related, consultation-related, interventions and outcome.

RESULTS

Compared with participants from the previous study, SIPC-2-2018 participants were significantly older (d = 0.54) and hospitalized for a longer duration (d = 0.20). The current study detected an increase in the proportion of referrals from surgical wards and for individuals affected by onco-hematologic diseases. Depressive disorders still represented the most frequent psychiatric diagnosis, followed by adjustment and stress disorders and delirium/dementia. Also, CLP psychiatrists prescribed more often antidepressants (Φ = 0.13), antipsychotics (Φ = 0.09), mood stabilizers (Φ = 0.24), and less often benzodiazepines (Φ = 0.07).

CONCLUSION

CLP workload has increased considerably in the past 20 years in Italy, with changes in patient demographic and clinical characteristics. A trend toward increase in medication-based patient management was observed. These findings suggest that the psychiatric needs of patients admitted to the general hospital are more frequently addressed by referring physicians, although Italian CLP services still deserve better organization and autonomy.

Proactive Integration of Mental Health Care in Hospital Medicine: PRIME Medicine

BACKGROUND

Proactive consultation-liaison (C-L) psychiatry has been shown to reduce hospital length of stay (LOS), increase psychiatric C-L consult rate, and improve hospital staff satisfaction. Nursing attrition has not been studied in relation to proactive C-L.

OBJECTIVE

Our primary aim in evaluating the proactive C-L service called Proactive Integration of Mental Health Care in Medicine (PRIME Medicine) is to analyze change in LOS over 10 months using historical and contemporary comparison cohorts. As secondary aims, we assess change in psychiatric consultation rate, time to consultation, and change in nurse attrition.

METHODS

PRIME Medicine was implemented in 3 hospital medicine units as a quality-improvement project. Team members systematically screened patients arriving to assigned units for psychiatric comorbidity. Identified patients were reviewed with hospitalist teams and nurses with the goal of early intervention.

RESULTS

Including historical and contemporary comparison cohorts, the mean sample age was 62.4 years (n = 8884). Absolute LOS was unchanged, but difference-in-difference analysis trended toward reduced LOS by 0.16 day (P = 0.08). Consultation rate increased from 1.6% (40 consults) to 7.4% (176 consults). Time to consultation was unchanged (4.0-3.8 d). Annual per-unit nursing turnover increased from 4.7 to 5.7 in PRIME units but from 8.5 to 12.0 in comparison units. Nurses citing "population" as the reason for leaving decreased from 2.7 to 1.7 in PRIME units but increased from 1.5 to 4.5 in comparison units. PRIME Medicine led to increased consultation rate, and our unit-wide outcomes provide a conservative estimate of effect. Factors that may have influenced effect size include our cohort's advanced age, considerable emergency department boarding times, increasing proportion of patients discharged to skilled nursing facilities, and concurrent LOS-reduction initiatives on all units. The favorable trends in nursing attrition on PRIME units may be explained in part by our prior finding that PRIME Medicine was associated with enhanced nursing satisfaction.

CONCLUSIONS

While PRIME Medicine had no more than a modest effect on LOS, it was associated with a markedly increased psychiatric consult rate and favorable trends in nursing retention. This analysis highlights important factors that should be considered when implementing and determining value metrics for a proactive C-L service.

Proactive Consultation-Liaison Psychiatry: American Psychiatric Association Resource Document

In 2019, the American Psychiatric Association Council on Consultation-Liaison (C-L) Psychiatry convened a work group to develop a resource document on proactive C-L psychiatry. A draft of this document was reviewed by the Council in July 2020, and a revised version was approved by this Council in September 2020. The accepted version was subsequently reviewed by the American Psychiatric Association Council on Health Care Systems and Financing in November 2020. The final version was approved by the Joint Reference Committee on November 24, 2020, and received approval for publication by the Board of Trustees on December 12, 2020. This resource document describes the historical context and modern trends that have given rise to the model of proactive C-L psychiatry. Styled as an inpatient corollary to outpatient collaborative care models, proactive C-L provides a framework of mental health care delivery in the general hospital designed to enhance mental health services to a broad range of patients. Its 4 elements include systematic screening for active mental health concerns, proactive interventions tailored to individual patients, team-based care delivery, and care integration with primary teams and services. Studies have found that proactive C-L psychiatry is associated with reduced hospital length of stay, enhanced psychiatric service utilization, reduced time to psychiatric consultation, and improved provider and nurse satisfaction. These favorable results encourage further studies that replicate and build upon these findings. Additional outcomes such as patient experience, health outcomes, and readmission rates deserve investigation. Further studies are also needed to examine a broader array of team compositions and the potential value of proactive C-L psychiatry to different hospital settings such as community hospitals, surgery, and critical care.

The Management Experiences, Priorities, and Challenges of Medical Directors in the Subspecialty of Consultation-Liaison Psychiatry: Results of a Needs Assessment

BACKGROUND

Medical directors need management skills, yet few studies describe the specific tasks that directors consider most important, their confidence for these tasks, and how their confidence develops. We studied these questions among directors in the subspecialty of Consultation-Liaison Psychiatry.

METHODS

A needs survey was sent to 48 registrants of a new forum for Consultation-Liaison Psychiatry directors. The survey asked about 6 professional experiences, the relative importance of 14 management tasks, and the directors' confidence in managing these tasks, using 7-point Likert scales. Correlations between experiences, task importance, and task confidence were performed.

RESULTS

Twenty-seven directors responded (56% response). The experiences that correlated most with management confidence were years in practice and health care leadership training, yet approximately half of responders were directors for ≤5 years and had received minimal training. Management tasks with the highest importance included demonstrating value of their service and roles for nonphysician clinical staff on their teams. Significant associations were identified between years in practice and confidence for leading faculty scholarship, trainee staffing ratios and roles, fee coding, measurement of faculty clinical productivity, and faculty recruitment. Leadership training correlated with confidence in demonstrating service value, measuring faculty clinical productivity, novel models of care, and growing a new service.

CONCLUSION

Consultation-Liaison directors with fewer years of experience and minimal health care management training need time and support to grow into their roles. They should be pointed toward training opportunities to improve their confidence to lead the wide range of management tasks that are important to their roles.
