Relationship between timeliness of contact and length of stay in older and younger patients of a consultation-liaison psychiatry service

An Observational Study of Proactive and On-Request Psychiatry Consultation Services: Evidence for Differing Roles and Outcomes

BACKGROUND

Proactive psychiatric consultation services rapidly identify and assess medical inpatients in need of psychiatric care. In addition to more rapid contact, proactive services may reduce the length of stay and improve staff satisfaction. However, in some settings, it is impractical to integrate a proactive consultation service into every hospital unit; on-request and proactive services are likely to coexist in the future. Prior research has focused on changes in outcomes with the implementation of proactive services.

OBJECTIVE AND METHODS

This report describes differences between contemporary proactive and on-request services within the same academic medical center, comparing demographic and clinical data collected retrospectively from a 4-year period from the electronic medical record.

RESULTS

The proactive service saw patients over four times as many initial admissions (7592 vs. 1762), but transitions and handoffs between services were common, with 434 admissions involving both services, comprising nearly 20% of the on-request service's total contacts. The proactive service admissions had a shorter length of stay and a faster time to first psychiatric contact, and the patients seen were more likely to be female, of Black race, and to be publicly insured. There were over three times as many admissions to psychiatry from the proactive service. The on-request service's admissions had a longer length of stay, were much more likely to involve intensive care unit services, surgical services, and transfers among units, and the patients seen were more likely to die in the hospital or to be discharged to subacute rehabilitation.

CONCLUSIONS

Overall, the results suggest that the two services fulfill complementary roles, with the proactive service's rapid screening and contact providing care to a high volume of patients who might otherwise be unidentified and underserved. Simultaneously, the on-request service's ability to manage patients in response to consult requests over a much larger area of the hospital provided important support and continuity for patients with complex health needs. Institutions revising their consultation services will likely need to consider the best balance of these differing functions to address perceived demand for services.

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.

Association between the timing of consultation-liaison psychiatry interventions and the length of stay in general hospital

BACKGROUND

Psychiatric comorbidities are frequent in patients admitted in general hospital and are associated with greater lengths of stay (LOS). Early consultation-liaison psychiatry (CLP) interventions may reduce the LOS but previous studies were underpowered to allow subgroup analyses and have generally not considered the severity of the condition for which patients were admitted ('disease severity').

AIMS

To investigate the association between the timing of CLP interventions and LOS in a general hospital.

METHOD

We retrospectively included 4500 consecutive patients admitted in non-psychiatric wards of a university hospital between 2008 and 2016 who had a first CLP intervention. We used general linear models to examine the association between the referral time, defined as log(days before the consultation)/log(LOS), and log(LOS), adjusting for age, gender, year of admission, place of residence, main psychiatric diagnosis, admission to the intensive care unit (ICU), main physical condition and disease severity.

RESULTS

Referral time was associated with log(LOS) (β = 0.31; P <0.001), notably for older patients (β = 0.43; P <0.001) and those admitted to the ICU (β = 0.50; P <0.001), but not for those with psychotic disorders (β = -0.20; P = 0.10). The association was confirmed when considering the expected LOS for each patient. For instance, for an expected LOS of 10 days, a CLP intervention on day 3 compared with day 6 was associated with a reduction of the actual LOS of 2.4 days.

CONCLUSIONS

Earlier CLP interventions were associated with a clinically significant shorter LOS in a large population even after adjusting for disease severity. Early CLP interventions may have benefits for both patients and health-related costs.

Time of referral to older adult liaison psychiatry service and other factors affecting length of stay in the general hospital

OBJECTIVES

To explore the relationship between social and clinical factors with (1) Time to referral to an older adult liaison psychiatry service, and (2) Length of stay (LOS), in a sample of older adults admitted to an acute general medical hospital receiving liaison psychiatry intervention, in London, United Kingdom, over a 3-year period.

METHODS

Information on patients referred to liaison psychiatry for older adults between January 2013 and December 2015 was collected using structured forms, with clinical diagnoses determined according to International Classification of Mental Disorders-10. The association of social and clinical factors with the time taken to refer to liaison psychiatry and LOS was assessed using Cox proportional hazards regression and zero-truncated Poisson regression, respectively.

RESULTS

Compared with people who were diagnosed with depression, older adults with psychotic and alcohol use disorders had higher rates of referral to liaison psychiatry (adjusted hazard ratios [aHRs] 1.83 [95% CI: 1.30, 2.59] and aHR 1.69 [95% CI: 1.01, 2.83]) respectively. In adjusted models, LOS was increased in older adults with delusional disorders and shorter in people with alcohol use disorders, personality disorders and learning disabilities, compared to people with depressive diagnoses. Within this cohort, a new definite dementia diagnosis and longer time to refer to liaison psychiatry were both associated with a longer length of general hospital in-patient stay.

CONCLUSIONS

In older adults admitted to general medical hospitals, and needing liaison psychiatry input, timely referral may be associated with a shorter LOS.

Mental Health Care in Pediatric Rehabilitation Hospitals: A Biopsychosocial, Collaborative, and Agency-based Service Integration Approach

Background: Canadian hospitals are not currently prepared to meet the psychosocial needs of children with disabilities as services are rooted in a biomedical care model. Objective: To describe a practical and holistic framework for pediatric rehabilitation hospitals to meet the health care needs of children and their families. Method: An environmental scan was conducted of best practice guidelines, policy documents, and models of integrated mental health care. Recommendations from clinical guidelines and national strategy documents were incorporated to develop a service integration approach. Results: An agency-based approach was used to develop a two-phase biopsychosocial framework. In framework Phase I, reactive care is provided to mental health concerns. In Phase II, there is a shift to proactive care and mental health wellbeing. Conclusions: Emphasis is placed on capacity building of clinical staff into best practices for mental health care. Implementation needs and consideration for uptake of the framework are also discussed.

Psychiatric Consultations in General Hospitals: A Scoping Review

Context: The rapid growth of psychiatric disorders requires psychiatric consultations to be provided on a greater scale, particularly for hospitalized patients. Objectives: The aim of this study was to evaluate the extent of psychiatric consultation requests in general hospitals and to identify potential gaps in the literature. Evidence Acquisition: This scoping review was based on relevant research published in Web of Science, Scopus, PubMed, Embase, and Cochrane (1977- Dec 2019). The collected literature was closely examined prior to selecting the applicable studies by means of peer review. Data were summarized within a framework of themes comprised of psychiatric consultation, prevalence of psychiatric disorders, hospital departments, diagnosis of psychiatric disorders, and nature of research prior to theoretical classification and tabulation. Results: Ultimately, 22 studies were included in this scoping review. Requests for psychiatric consultations were highest in Austria and Italy, with 22.6% and 13.6% of cases, respectively. The majority of requests were from internal and surgical departments. Consultations were requested more frequently for female patients compared to male patients. mood disorders and substance use disorder were the most diagnostic reports. Conclusions: Taking into consideration the prevalence of psychiatric disorders in patients suffering from physical illnesses, the referral rate results were considerably low. Although the frequency of psychiatric consultation reports vary widely between countries. As we limited the review to articles written in English, this may be due to selection bias. In this review, we identified that methodological differences and the use of different diagnostic criteria are major gaps that limit a definitive statistical comparison between studies.

Implementation of the CLiP database

PURPOSE

The purpose of this paper is to review the findings from an audit of the implementation of a consultation-liaison psychiatry (CLiP) database in all inpatients referred to a CLiP service at the largest hospital in Malaysia with the aim of improving the quality CLiP services.

DESIGN/METHODOLOGY/APPROACH

All inpatient referrals to the CLiP team were recorded over a three-month period and compared to previous audit data from 2017. Four audit standards were assessed: the reporting of referrals, timeliness of response indication of reason for referral and presence of a management plan.

FINDINGS

The compliance of reporting using the CLiP form was 70.1 per cent compared to 28 per cent in the audit data from 2017 after interventions were conducted. Analysis of the completed CLiP form reveals that 89 per cent of referrals were seen within the same working day. All referrals included the reason for referral. The most common reason for referral was for depressive disorders, but post-assessment, delirium was the most common diagnosis. In total, 87.8 per cent satisfied the audit criteria for a completed written care plan.

ORIGINALITY/VALUE

Specialised CLiP services are relatively new in Malaysia and this is the first paper to examine the quality of such services in the country. Interventions were effective in improving the compliance of reporting using the CLiP database. The findings suggest that the CLiP services are on par with international audit standards. Furthermore, data from this clinical audit can serve as a benchmark for the development of national operating policies in similar settings.

Need analysis for a new high acuity medical psychiatry unit: which patients are considered for admission?

BACKGROUND

The study aims were: to estimate the proportion of patients with an indication for admission to a new high acuity Medical Psychiatric Unit (MPU), to explore the reasons for MPU-admission according to different health disciplines, and to check for differences in patient characteristics. The results of this study are to be utilized in the proposed establishment of a high-acuity MPU in a University Medical Center. Such a unit currently does not exist at Erasmus MC.

METHODS

Hospital in-patients were included if they received psychiatric consultation from the Psychiatric Consultative Service (PCS). As part of the study protocol, psychiatrists, other medical specialists, and nurses determined the need for admission to the proposed MPU. Patient groups were compared with respect to diagnoses, socio-demographic characteristics and patient routing.

RESULTS

One hundred and fifty-one patients were included, 43% had an indication for MPU-admission, for the other patients PCS involvement was sufficient. There was agreement on suicide attempts as a reason for MPU-admission. For psychiatrists, the need for further diagnostic evaluation was a common reason for MPU admission, while other medical specialists more often emphasized the need for safety measures. Patients with an unplanned hospital admission had a higher chance of MPU eligibility (OR = 2.72, 95% CI 1.10-6.70). The main psychiatric diagnoses of MPU-eligible patients were organic disorders (including delirium), mood disorders, and disorders related to substance abuse. The most common diagnoses found were similar to those in previous research on MPU populations.

CONCLUSION

Different medical disciplines have different views on the advantages of MPUs, while all see the need for such facilities. The proposed MPU should be able to accommodate patients directly from the Emergency Unit, and the MPU should provide specialized diagnostic care in an extra safe environment.

Socio-demographic characteristics and factors associated with hospitalization in psychiatry of old age patients: an international comparison between Ireland and Turkey

BACKGROUND

Taking predictors of hospitalization characteristics into consideration internationally would broaden our understanding of this population on a local basis.

AIMS

We aimed to examine and compare socio-demographic profiles along with hospitalization characteristics including length of hospital stay (LOS), reasons for admission and diagnoses among older adult inpatients hospitalized in Ireland and Turkey, and to assess factors predicting these features.

METHODS

The admission charts of 356 psychiatric inpatients over 65 years of age who were admitted to two different acute psychiatric hospitals (Sligo/Ireland and Istanbul/Turkey) were analysed by means of descriptive modalities and logistic regression.

RESULTS

There were significant differences in several domains of socio-demographics, reasons of admission and diagnoses. LOS was significantly longer in Ireland. Living alone was the only significant predictor for longer LOS in both countries, whereas in addition to living alone, younger age was also a contributor for longer LOS in Turkey.

DISCUSSION

Given that the only factor predicting LOS both in Turkey and Ireland was living alone, helping to identify more acceptable ways of providing social support for living arrangements constitutes an important service to shorten LOS in old age psychiatric population.

CONCLUSIONS

It is possible to infer that independent from the cultural diversities, living arrangement is a consistent entity to influence length of hospital stay in older adult population.

Outcomes after traumatic injury in patients with preexisting psychiatric illness

BACKGROUND

Patients with psychiatric illness have been shown to experience higher rates of traumatic injury. Injury patterns, treatment decisions, and outcomes have not been well characterized in patients with psychiatric illness after injury, in particular those who undergo acute surgical intervention. The purpose of this analysis was to determine mortality, complications, and surgical intervention rates in patients with psychiatric illness after traumatic injury.

METHODS

This is a retrospective study of trauma patients ≥18 years old admitted to LAC + USC Medical Center between January 2008 and March 2015. Patients with psychiatric diagnoses were identified using ICD-9 diagnosis codes. Multivariate logistic regression analyses taking into account demographic and injury characteristics were used to identify associations between psychiatric comorbidity, injury mechanism, surgical interventions, and outcomes in patients after injury.

RESULTS

A total of 26,502 patients were analyzed. Of these, 3,040 (11.5%) had a documented psychiatric comorbidity (2.0% depressive disorder, 0.8% bipolar disorder, 1.3% schizophrenia, 0.5% anxiety disorder, 3.2% substance use disorder). Patients with psychiatric illness were significantly older (49.6 years vs. 42.0 years, p < 0.001), had a lower proportion of penetrating injuries (13.8% vs. 18.1%, p < 0.001), and had a higher incidence of self-inflicted injuries (11.6% vs. 0.72%, p < 0.001). No difference in gender distribution was observed (74.2% men vs. 74.4% men, p = 0.80). Overall mortality was similar in both groups (adjusted odds ratio [aOR], 0.73; p = 0.07). Patients with psychiatric illness were significantly less likely to undergo acute surgical intervention within 6 hours of emergency department admission (aOR, 0.64; p < 0.001). Time from ED arrival to consent for acute surgical intervention was similar in both groups (94.8 min vs. 93.0 min, p = 0.84). No significant difference in mortality after acute surgical intervention was observed (aOR, 0.26; p = 0.10). Psychiatric illness was associated with a significantly higher likelihood of developing complications (aOR, 1.90; p < 0.001) and longer hospital lengths of stay (10.6 days vs. 6.2 days, p < 0.001).

CONCLUSIONS

Trauma patients with comorbid psychiatric illness were observed to have lower rates of acute surgical interventions, higher complication rates, and longer hospital lengths of stay. Further studies are needed to better characterize the causative factors underlying these associations.

A comparison of two psychiatric service approaches: findings from the Consultation vs. Liaison Psychiatry-Study

BACKGROUND

Psychiatric comorbidities are common in somatically ill patients. There is a lack of data that can provide clear insights into substantial comparative advantages of different Consultation/Liaison Psychiatry (CLP) services.

METHODS

The Consultation versus Liaison Psychiatry-Study collected and analyzed data of 890 primarily somatically ill hospital inpatients presenting with psychiatric symptoms in a prospective observational study design. One group was treated via a liaison-model (LM) with regular consultation hours, the other via an on-demand-model (ODM) with individually requested consultations.

RESULTS

Five hundred forty-five LM and 345 ODM patients were compared. Patients in the LM were, on average, older compared to the patients of the ODM. The vast majority (90.8%) of individuals for whom a psychiatric consultation was requested came from internal medicine. The most common diagnoses were affective disorders (39.3%), organic mental disorders (18.9%), alcohol-induced mental disorders (11.3%) and reactions to severe stress/adjustment disorders (10.4%). Organic mental disorders were significantly more common in patients seen in the LM (24.0% vs. 10.3%, p < 0.001) while affective disorders were more frequently diagnosed in the ODM (46.6% vs. 34.8%, p = 0.001). Patients seen in the ODM were, on average, more severely affected compared to patients seen in the LM and required more extensive treatment. 16.3% of ODM patients were regarded as potentially suicidal; among these, 3.5% were acutely suicidal and 12.8% latently suicidal. Any form of further treatment was required by 93.0% of ODM patients compared to 77.8% in the LM. Pharmacological treatment with benzodiazepines, usually used as short-term treatment, was more frequently prescribed to patients seen in the ODM while patients seen in the LM were more often started on selective serotonin reuptake inhibitors, indicative of long-term treatment.

CONCLUSIONS

Patients in need of less acute treatment were considerably less common in the ODM. The data indicate a possible risk of such patients to remain unrecognized. A quasi-liaison model is recommended to be the best suitable and cost-effective way of providing psychiatric care to somatically ill patients with psychiatric comorbidities.

Practice Patterns Revisited in Pediatric Psychosomatic Medicine

BACKGROUND

Given the heightened focus on the implementation of integrated care and population health management strategies, there is a critical need for an analysis of pediatric psychosomatic medicine (PPM) programs.

OBJECTIVE

The goal was to survey current practice patterns in academic PPM programs in North America regarding their service composition, clinical consultation services, changes in service demand, funding, and major challenges so as to inform and support advocacy efforts on behalf of children in their need for responsive and effective PPM services.

RESULTS

With a 52.5% survey response rate from 122 child and adolescent psychiatry programs in North America, the demand for PPM services was reported to have significantly increased over the past decade as seen in the described expansion in clinical consultation services and the reported higher patient acuity, as well as new responsibilities in the care of youth with psychiatric illnesses who require boarding on medical inpatient services. Although an increased willingness by hospital administrators to fund PPM services was apparent, adequate funding remained a core issue. Although the value of research is well recognized, few programs are engaged in systematic PPM investigation.

CONCLUSION

This survey provides evidence that the current field of PPM appears to be in an increasingly stronger position within academic medical centers. It is just as apparent today, as it has been in the past, that there is a need to communicate at local, regional, and national levels that PPM is an essential behavioral health service.
