The effect of a hospital liaison psychiatry service on inpatient lengths of stay: interrupted time series analysis using routinely collected NHS hospital episode statistics.

BACKGROUND: The purpose of the study was to determine whether establishment of a specific liaison psychiatry service designed to offer a rapid response with facilitated hospital discharge led to reduced acute hospital length of inpatient stay. METHODS: We used interrupted time series based upon routine NHS data from secondary care service in two acute general hospitals, for all adult (16+ years) inpatient admissions (114,029 inpatient spells representing 70,575 individual patients) over 3 years. RESULTS: Length of stay reduced over time in both hospitals. Against a background of falling length of stay across the study period, there was no discernible effect of the rapid access/early discharge liaison service on length of stay, either as a step change or linear decline. This finding held for all patients and for those over 65 years and those discharged with a mental health diagnosis. CONCLUSIONS: Using routine NHS data for a whole hospital it was not possible to replicate a previous report that a rapid access liaison psychiatry service for inpatients produces substantial reductions in length of stay, and commissioners of services should be cautious of claims to the contrary. Further research to determine if there is an effect for sub-groups will require major improvements in the way co-morbid mental disorders are coded in NHS practice.

Recovery-focused mental health care planning and co-ordination in acute inpatient mental health settings: a cross national comparative mixed methods study.

BACKGROUND: Involving mental health service users in planning and reviewing their care can help personalised care focused on recovery, with the aim of developing goals specific to the individual and designed to maximise achievements and social integration. We aimed to ascertain the views of service users, carers and staff in acute inpatient wards on factors that facilitated or acted as barriers to collaborative, recovery-focused care. METHODS: A cross-national comparative mixed-methods study involving 19 mental health wards in six service provider sites in England and Wales. This included a survey using established standardised measures of service users (n = 301) and staff (n = 290) and embedded case studies involving interviews with staff, service users and carers (n = 76). Quantitative and qualitative data were analysed within and across sites using descriptive and inferential statistics, and framework method. RESULTS: For service users, when recovery-oriented focus was high, the quality of care was rated highly, as was the quality of therapeutic relationships. For staff, there was a moderate correlation between recovery orientation and quality of therapeutic relationships, with considerable variability. Staff members rated the quality of therapeutic relationships higher than service users did. Staff accounts of routine collaboration contrasted with a more mixed picture in service user accounts. Definitions and understandings of recovery varied, as did views of hospital care in promoting recovery. Managing risk was a central issue for staff, and service users were aware of measures taken to keep them safe, although their involvement in discussions was less apparent. CONCLUSIONS: There is positive practice within acute inpatient wards, with evidence of commitment to safe, respectful, compassionate care. Recovery ideas were evident but there remained ambivalence on their relevance to inpatient care. Service users were aware of efforts taken to keep them safe, but despite measures described by staff, they did not feel routinely involved in care planning or risk management decisions. Research on increasing therapeutic contact time, shared decision making in risk assessment and using recovery focused tools could further promote personalised and recovery-focused care planning. This paper arises from a larger study published by National Institute for Health Research (Simpson A, et al, Health Serv Deliv Res 5(26), 2017).

Changes over time of the diagnostic and therapeutic characteristics of patients of a psychiatric intensive care unit in Austria.

OBJECTIVE: The aim of this repeated cross-sectional study was to compare patients from a psychiatric intensive care unit (PICU) over ≫30 years regarding their diagnostic and therapeutic characteristics. METHOD: Three samples including 100 consecutive inpatients each from the Viennese PICU were submitted to a chart review: sample no. 1 from the years 1985/86, no. 2 from 1995/96 and no. 3 from 2007/08. RESULTS: Changes in referral modes were associated with a decrease of patients with substance induced disorders and an increase of patients with affective disorders over time. The rate of admissions after accidents and suicides was stable. The use of cranial MRI increased, while intravenous psychopharmacotherapy and parenteral nutrition decreased. Involuntary admission occurred in 43% and in 37% of patients physical restraints were necessary. We saw a shift from tricyclic antidepressants to SSRIs and SNRIs from sample 1 to 3. Likewise, we observed the emergence of atypical antipsychotics and a reduction of use of typical neuroleptics mainly from sample 2 to 3. The percentage of patients receiving benzodiazepines increased over time, while the mean dosage of benzodiazepines decreased. 7% of patients received electroconvulsive therapy. CONCLUSIONS: The changes over time in our samples reflect the medical progress made during the last decades. Future studies should focus on evaluation of efficacy of psychiatric intensive care using standardized measurements.

Five-year rehospitalization experience of a state-wide cohort of persons with schizophrenia.

PURPOSE: This study has the objective of assessing the psychiatric rehospitalization experience of a large cohort of persons with schizophrenia and modeling the effects of personal and systemic conditions on rehospitalization risk. METHODS: The study employs a secondary analysis of US data from Massachusetts' casemix database of all patients discharged from acute general hospital units. It focuses on 11,291 patients during 1994-2000 who were discharged from acute adult psychiatric units. Predictors used include basic demographics, length of stay, continuity of care with doctors and facilities, diagnoses, discharge referral, type of insurance, and distance to and selected socioeconomic characteristics of the patient's home zip code. Data are analyzed with descriptive statistics and modeled with the Cox proportional hazard model. The model was assessed through split-half reliability testing, the generalized R2, and Harrell's Concordance Index. RESULTS: Overall, 13.4% of patients were rehospitalized within 1 month; 38.9% within 1 year; and 64.1% within 5 years. Predictors that are most strongly associated with lower rehospitalization rates include continuity of care, discharge to a chronic hospital, and density of home zipcode, whereas discharge to another acute psychiatric unit had the greatest effect on increasing risk of rehospitalization. Overall the Cox model has generalized R2 of 0.343 and a Concordance Index of 0.734. CONCLUSIONS: The results highlight the need to enhance the continuity of the relationships with providers, whether these are with the assigned psychiatrists or other therapists and case managers, as well as workplace issues involving staff turnover and hospital assignment and admitting policies.

Microdecisions instead of coercion: patient participation and self-perceived discrimination in a psychiatric ward.

Aims: Patients may experience unfair reception when in contact with psychiatric services. The aims are to illuminate these perceptions, and the extent of inpatients' involvement in their care, and if degree of involvement depends on compulsory or voluntary care. Furthermore, we sought to determine if an educational intervention for staff members, including systematic listening and offering the inpatients involvement using microdecisions, affects the inpatients' experiences and the use of coercion. Materials and methods: We used a naturalistic setting case control design in two psychiatric wards for one year, including all inpatients (n = 685) of which 458 took part of the microdecision intervention. Structured direct interviews were carried out with inpatients based on the Discrimination and Stigma Scale (DISC), Dyadic OPTION, and CollaboRATE instruments before (n = 19) and after (n = 46) the intervention. Frequencies of coercive measures before and after the intervention were compared (n = 685). Results: Respondents subjected to the intervention experienced less discrimination related to psychiatric care compared to responders not subjected. Tendencies of improvements post intervention were found for some aspects of involvement, as attention to concerns and possibilities to ask questions. A decrease in the use of coercive measures at three and six months after the start of the intervention was observed. Conclusion: Results suggest that the intervention could decrease the inpatients' experiences of discrimination during psychiatric care as well as the use of coercion in the service. The Dyadic OPTION instrument showed a mixed picture with results implying improvements in some areas and impairments in others.

Effect of an vitamin D deficiency on depressive symptoms in child and adolescent psychiatric patients - a randomized controlled trial: study protocol.

BACKGROUND: Depression is a significant health and economic burden worldwide affecting not only adults but also children and adolescents. Current treatment options for this group are scarce and show moderate effect sizes. There is emerging evidence that dietary patterns and specific nutritional components might play a role in the risk for developing depression. This study protocol focusses on the role of vitamin D which is for long known to be relevant for calcium and phosphorous homeostasis and bone health but might also impact on mental health. However, the assessment of the vitamin D status of depressed juvenile patients, or supplementation of vitamin D is currently not part of routine treatment. Controlled intervention studies are indispensable to prove whether a vitamin D deficiency ameliorates depressive symptoms. METHODS/DESIGN: This double blinded, randomized controlled trial will enroll 200 inpatients from a child and adolescent psychiatric department with a vitamin D deficiency defined by a 25(OH)-vitamin D-level < 30 nmol/l (12 ng/ml) and a Beck Depressions Inventory (BDI-II) score > 13 (indicating at least: mild depression). Upon referral, all patients will be screened, checked for inclusion criteria, and those eligible will be randomized after written consent into a supplementation or placebo group. Both study-arms will receive treatment-as-usual for their psychiatric disorder according to established clinical guidelines. The participants of the vitamin D supplementation group will receive 2640 I.E. vitamin D3 q.d. for 28 days in accordance with best practice in pediatric endocrinology. We hypothesize that delaying supplementation of vitamin D in the placebo arm will affect the treatment success of the depressive symptomatology in comparison to the vitamin D supplementation group. Patients will be enrolled for a period of 28 days based on the mean length of hospitalization of juveniles with depression. DISCUSSION: Randomized controlled trials in children and adolescents with depression are needed to elucidate the role of a vitamin D deficiency for mental disorders and to investigate the relevance of a routine assessment and supplementation of vitamin D deficits. TRIAL REGISTRATION: DRKS00009758, 16/06/2016 (retrospectively registered).

Use of mechanical and pharmacological restraint over an eight-year period and its relation to clinical factors.

BACKGROUND: Use of restraint and finding the balance between security and ethics is a continuous dilemma in clinical psychiatry. In daily clinic and in planning health-care service, knowledge on the characteristics of restraint situations is necessary to optimize its use and avoid abuse. METHODS: We describe characteristics in the use of pharmacological and mechanical restraint in psychiatric acute wards in a hospital in Middle Norway over an eight-year period. Data on all cases of mechanical and pharmacological restraint from 2004 to 2011 were retrospectively collected from hand-written protocols. Complementary information on the patients was obtained from the hospital patient administrative system. RESULTS: Restraint in acute wards was used on 13 persons per 100,000 inhabitants annually. The percentage of admitted patients exposed to restraint was 1.7%, with a mean of 4.5 cases per exposed patient. Frequency per 100 admitted patients varied from 3.7 (in 2007) to 10 (in 2009). The majority of restraint cases concerned male patients under 50 years and with substance-abuse, psychotic, or affective disorders. Significantly more coercive means were used during daytime compared to night and morning. There was a significant increase in pharmacological coercion during spring and mechanical coercion during summer. CONCLUSIONS: Restraint was used on 1.7% of admitted patients, representing 13 per 100,000 inhabitants per year. Use of restraint was higher during certain periods of the day and was associated with the patient's diagnosis, age, gender, and legal status of hospitalization. There was a marked variation over the years.

Outcome of neuropsychiatric symptoms and daily functioning of patients with dementia treated on an acute psychogeriatric ward.

BACKGROUND: Dementia is associated with progressive deterioration in multiple cognitive domains, functional impairment and neuropsychiatric symptoms (NPS). AIMS: The aim of this study was to explore the factors associated with the outcome of NPS and daily functioning in patients with dementia during acute psychogeriatric hospitalization. MATERIALS AND METHOD: The data (n = 175) were collected between 2009 and 2013 in naturalistic settings on one acute psychogeriatric ward at one university hospital in Finland. Behavioural symptoms were assessed using the Neuropsychiatric Inventory (NPI) and activities of daily living using the Alzheimer's Disease Cooperative Study-Activities of Daily Living (ADCS-ADL). RESULTS: During the hospital stay (45 days ±30.4) NPI total score decreased from 33.9 to 18.2 (p < .001). Daily functioning score decreased from 31.7 to 20.9 (p < .001). The number of patients taking antipsychotics (96-130, p = .004) and anxiolytics (54-102, p < .001) increased from admission to discharge. Overall mean dosage (mg/day) of antipsychotics (from 40.2 to 72.0 in chlorpromazine equivalents, p < .00) and anxiolytics (from 3.43 to 7.47 in diazepam equivalents, p < .001) also increased. Higher antipsychotic dosage at discharge was a significant predictor for large NPI score change (p = .002) indicating better symptom reduction. Neither higher antipsychotic dosage or anxiolytic dosage at discharge were significant predictors for ADL score change. CONCLUSIONS: Neuropsychiatric symptoms improved while deterioration was found in daily functioning from admission to discharge. Higher antipsychotic dosage at discharge was a predictor for larger NPI score change indicating better symptom reduction. Preventing threatening ADL decline during hospital stay is especially important.

No regrets: Young adult patients in psychiatry report positive reactions to biobank participation.

BACKGROUND: Research in vulnerable individuals must insure voluntariness and minimize negative reactions caused by participation. This study aimed to describe consent and completion rate in young psychiatric patients in relation to study components, degree of disability and to compare response to research participation in patients and controls. METHODS: Between 2012 and 2015, 463 patients with psychiatric disorders between the ages of 18-25 from the Dept. of General Psychiatry at Uppsala University Hospital and 105 controls were recruited to donate data and samples to a biobank. Consent and completion in relation to questionnaires, biological sampling of blood, saliva or feces, were monitored. Both groups were also asked about their perceived disability and how research participation affected them. RESULTS: Most patients who participated consented to and completed questionnaires and blood sampling. The majority also consented to saliva sampling, while less than half consented to collect feces. Of those who gave consent to saliva and feces only half completed the sampling. Both patients and controls reported high voluntariness and were positive to research participation. Within the patient group, those with greater perceived disability reported greater distress while participating in research, but there was no difference in consent or completion rates or level of regret. CONCLUSIONS: With the described information procedures, psychiatric patients, regardless of perceived disability, reported high voluntariness and did not regret participation in biobanking. Compared to questionnaires and blood sampling, given consent was reduced for feces and completion was lower for both saliva and feces sampling.

Substance-related psychopathology and aggressiveness in a nightlife holiday resort: Results from a pilot study in a psychiatric inpatient unit in Ibiza.

OBJECTIVES: We aimed to describe a sample of subjects admitted to a psychiatric unit after the intake of psychoactive substances for recreational purposes. METHODS: Between June and September 2015, 49 subjects were included. Sociodemographic characteristics and psychopathological aspects were investigated, and urine samples for further analysis were collected. Three subgroups (cannabinoids, stimulants, and depressors users) were identified, according to the structured interview regarding substance use and urinalysis. RESULTS: Level of aggressiveness was found to be significantly higher (p < .05) in the cannabinoids subgroup. Self-reported symptom severity was comparable among groups, but trends could be identified: SCL-90 results showed a prevalence of anxiety symptoms among depressors users, hostility or aggression in the tetrahydrocannabinol subgroup, and psychoticism in the stimulants subgroup. CONCLUSIONS: The use of psychoactive substances was be characterised by poly-use of both traditional and novel substances. The presence of aggressiveness emerged as a main feature associated with the use of cannabis and other cannabinoids. Binge drinking and sleep deprivation also represented a relevant component in almost all the evaluated subjects.

An analysis of the federal funding for mental health care in Brazil.

This article analyzes spending on mental health by the Brazilian Ministry of Health between 2001 and 2014. It is documental research of the Brazilian Ministry of Health's databases. It analyzes the data using descriptive statistical analysis. Total spending on mental health for the period 2001 to 2014 shows a percentage increase in resources destined for outpatient care, but this increase is a reallocation from hospital services to community-based services and total resources for the mental health program remain at an average of 2.54% of the total health budget. Within outpatient expenditure, spending on medications remains high. Professionals committed to psychiatric reform fight to guarantee that a small fraction of the surplus appropriated by the state is directed towards social policies.

Treatment of agitation in the acute psychiatric setting. An observational study of the effectiveness of intramuscular psychotropic medication.

BACKGROUND: Agitation is frequent in the acute psychiatric setting. The observation and treatment of agitation is important to avoid harm to patients or staff, to reduce distress of the patient, and to reduce the risk of coercion, especially physical restraint. AIM: To evaluate the effect of intramuscular treatment with psychotropics on agitation in a non-selected acute psychiatric population. METHODS: The Positive and Negative Syndrome Scale Excitement Component (PANSS-EC) was implemented in the acute psychiatric ward at Psychiatric Center Copenhagen to improve assessment and treatment of agitation. During a period of almost ~2 years the staff was requested to assess agitation before and after administration of intramuscular injections. RESULTS: PANSS-EC was obtained at baseline and within 2 hours after injection for 135 injections with antipsychotics or benzodiazepines administered to 101 acute, non-selected psychiatric patients with high occurrence of co-morbid substance abuse. Mean PANSS-EC at baseline was 26.53 ± 4.87, and mean reduction in PANSS-EC was 14.99 ± 8.48 (p < 0.001). For 73% of injections PANSS-EC decreased with ≥40% (generally accepted definition of response). In 49% of cases patients were subjected to physical restraint. Patients subjected to restraint had a significantly higher PANSS-EC score. Patients who received a subsequent injection had a significantly lower decline in PANSS-EC score. Besides two cases of acute dystonia following haloperidol injections, no serious side-effects were observed. CONCLUSIONS: Treatment of agitation with intramuscular injections of psychotropics was in general effective in this non-selected, highly agitated psychiatric population, and injections were well tolerated.

Transferring psychiatric specialist services to local authorities-Characteristics of the patients involved.

BACKGROUND: To obtain more co-ordinated services, better co-operation between the services and more efficient use of resources, a pilot project for transferring some district psychiatric centres (DPCs) to large municipalities is planned by the Norwegian government. Systematic knowledge about the patients involved is needed when clinical needs and standards, funding, and political agendas are discussed. This study identifies the clinical, socio-demographic, and behavioural characteristics of patients who need services from both the municipality and the DPC. METHOD: A national mapping of patients in specialist mental health services was conducted in 2012/2013, including 65% of all inpatients (n = 2358) and 60% of all outpatients (n = 23 124). The need for services was assessed by each patient's clinician. RESULTS: It was found that 74% of inpatients and 43% of outpatients needed one or more services from the municipality, usually involving housing, mental health treatment/therapy, or economic support according to their clinicians. These were typically patients with severe mental illness, young inpatients, older outpatients and persons with low education and weak social networks. Only small differences in the need for municipal services were found between patients in hospitals and DPCs. CONCLUSIONS: Many of the patients in specialist mental health services, especially the inpatients, needed services from municipal social and health services. Because these patients had the most severe mental illnesses and were the most socially deprived, a stronger integration of service levels would potentially benefit these patients most. The pilot project should be evaluated to identify the consequences for patients, staff, quality of services, and costs of transferring services to a lower system level.

Changes in the clinical features of child and adolescent psychiatric inpatients: a nationwide time-trend study from Finland.

BACKGROUND: Few studies have focused on the recent trends in clinical features child and adolescent inpatient. AIMS: This study focuses on the change in the characteristics of child and adolescent psychiatric inpatients in Finland. METHODS: The data collection was carried out on selected study days in 2000 and 2011. Questionnaires were sent to the psychiatrists of all child and adolescent wards in Finland. RESULTS: By comparing the data obtained in 2000 (n = 504) and 2011 (n = 412), several changes were found: the percentage of girls in adolescent wards grew and the diagnoses of depression, anxiety disorders, attention deficit hyperactivity disorder and eating disorders increased. In contrast, the diagnoses of psychosis and conduct or oppositional disorders decreased. General functioning was evaluated with the Childrens Global Assessment Scale (CGAS). There were no changes in the distribution of CGAS scores among child inpatients, whereas among adolescents the share of inpatients with lowest CGAS scores (1-30) increased significantly. The mean length of stay dropped. CONCLUSIONS: The growing percentage of girls in adolescent wards is associated with an increase in diagnoses that are more prevalent among girls than boys, namely depression, anxiety, and eating disorders. The changes in the distribution of diagnoses may be due to changes in diagnostic or referral practices, or reflect true changes in the prevalence of disorders among children and adolescents in need of inpatient treatment. The share of adolescent inpatients with the poorest general functioning has increased. The observed shortening in inpatient treatment time seems to be a result of changes in treatment practices.

Impact of a postdischarge smoking cessation intervention for smokers admitted to an inpatient psychiatric facility: a randomized controlled trial.

INTRODUCTION: Persons with a mental disorder smoke at higher rates and suffer disproportionate tobacco-related burden compared with the general population. The aim of this study was to determine if a smoking cessation intervention initiated during a psychiatric hospitalization and continued postdischarge was effective in reducing smoking behaviors among persons with a mental disorder. METHODS: A randomized controlled trial was conducted at an Australian inpatient psychiatric facility. Participants were 205 patient smokers allocated to a treatment as usual control (n = 101) or a smoking cessation intervention (n = 104) incorporating psychosocial and pharmacological support for 4 months postdischarge. Follow-up assessments were conducted at 1 week, 2, 4, and 6 months postdischarge and included abstinence from cigarettes, quit attempts, daily cigarette consumption, and nicotine dependence. RESULTS: Rates of continuous and 7-day point prevalence abstinence did not differ between treatment conditions at the 6-month follow-up; however, point prevalence abstinence was significantly higher for intervention (11.5%) compared with control (2%) participants at 4 months (OR = 6.46, p = .01). Participants in the intervention condition reported significantly more quit attempts (F[1, 202.5] = 15.23, p = .0001), lower daily cigarette consumption (F[4, 586] = 6.5, p < .001), and lower levels of nicotine dependence (F[3, 406] = 8.5, p < .0001) compared with controls at all follow-up assessments. CONCLUSIONS: Postdischarge cessation support was effective in encouraging quit attempts and reducing cigarette consumption up to 6 months postdischarge. Additional support strategies are required to facilitate longer-term cessation benefits for smokers with a mental disorder.

Assessing overall functioning with adolescent inpatients.

The current study sought to evaluate the validity and reliability of a brief measure of overall functioning for adolescents. Clinicians were asked to complete the Overall Functioning Scale (OFS) for 72 adolescents consecutively admitted to the adolescent psychiatric inpatient service of a community safety net medical center. The results revealed that this new measure is related to the patients' length of stay, clinician-rated measures of social cognition and object relations, Global Assessment of Functioning (GAF) score at admission, as well as global rating of engagement in individual psychotherapy. The results also showed that the OFS was related to the patients' history of nonsuicidal self-harm as well as treatment outcome as assessed by measures of psychological health and well-being as well as symptoms. Hierarchical regressions reveal that the OFS shows incremental validity greater than the admission GAF score in predicting length of stay. The results also showed that the OFS demonstrates interrater reliability in the excellent range (intraclass correlation coefficient(1,2)) of 0.88. Clinical implications of the use of this tool and areas of future research are discussed.

Associations between psychiatric inpatient bed supply and the prevalence of serious mental illness in Veterans Affairs nursing homes.

OBJECTIVES: We assessed whether reductions in inpatient psychiatric beds resulted in transinstitutionalization to nursing home care of patients with serious mental illness (SMI) within the Veterans Health Administration (VHA). METHODS: We assessed trends in national and site-level inpatient psychiatric beds and nursing home patient demographics, service use, and functioning from the VHA National Patient Care Database, VHA Service Support Center Bed Control, and VHA Minimum Data Set. We estimated nursing home admission appropriateness using propensity score analyses based on Michigan Medicaid Nursing Facility Level of Care Determinations ratings. RESULTS: From 1999 to 2007, the number of VHA inpatient psychiatric beds declined (43,894-40,928), the average inpatient length of stay decreased (33.1-19.0 days), and the prevalence of SMI in nursing homes rose (29.4%-43.8%). At site level, psychiatric inpatient bed availability was unrelated to SMI prevalence in nursing home admissions. However, nursing home residents with SMI were more likely to be inappropriately admitted than were residents without SMI (4.0% vs 3.2%). CONCLUSIONS: These results suggest the need for increased attention to the long-term care needs of individuals with SMI. Additional steps need to be taken to ensure that patients with SMI are offered appropriate alternatives to nursing home care and receive adequate screening before admission to nursing home treatment.

"Talking in a new way": older individuals' experiences of group work in an acute psychiatric ward.

Group work is frequently used in mental health, however qualitative studies on service-users' views are rare. Semistructured interviews explored 12 participants' experiences of a café-style social group and a mutual-aid group offered on an older persons psychiatric ward in Christchurch, New Zealand. The values of the strengths-based approach underpinning the groups were reflected back in the experience of an affirming environment, an exchange of strengths, and the capacity to change. The appeal of the café-style may be culturally specific to European women however, reinforcing the importance of an awareness of culture and diversity.

DRGs and other patient-, service- and area-level factors influencing length of stay in acute psychiatric wards: the Veneto Region experience.

PURPOSE: This study aimed to identify services-related and area-based measures together with socio-demographic factors that could improve diagnosis-related groups in explaining length of stay variability in general hospital psychiatric units in Veneto Region (North East of Italy). METHODS: Data were collected from the regional hospital discharge records database. A hierarchical multiple regression model with only diagnosis-related groups as predictors of actual and ln-transformed length of stay was compared with a second model in which patient-, service- and area-level variables were included. Local health district was used as group-level in the hierarchical multiple regression analysis. RESULTS: The only diagnosis explains 6.4% of actual length of stay total variance (14.8% for ln-transformation). In the second model length of stay resulted related also to gender, age, severity of hospitalization, patient's local health district, number of psychiatrists, psychologists, hospital attendants/nurses, social workers and educators in the general hospital psychiatric units, number of outpatients in each local health district and percentages of divorced and single people, with almost a 2% point increase on actual length of stay in explained variance (5% point increase for ln-transformation). CONCLUSIONS: For the first time the hospital discharge card regional survey of all public acute inpatient psychiatric facilities in Veneto Region were used. The innovative aspect of this study was the attempt to investigate the relationship between length of stay and other indexes, characterizing not only the inpatient facilities, but also the resident population structure in each area. The information about factors that influence length of stay can be useful to inform service planning and resource allocation.
