Impact of acute stroke team emergency calls on in-hospital delays in acute stroke care.

INTRODUCTION: Acute stroke is a medical emergency. Therefore, early recognition and rapid activation of the medical system are important prerequisites for successful management. We sought to investigate the impact of our new Acute Stroke Team emergency call system (AST) on admission delays from the emergency department (ED) to the stroke care unit (SCU) and on the subsequent length of stay (LOS) and in-hospital mortality. METHODS: We retrospectively analysed data obtained from the Austin Hospital stroke unit database and the electronic medical record/patient tracking system for the 5 months before (August to December 2004) and after (January to May 2005) the introduction of the AST. RESULTS: Data for 352 patients were extracted. Of these, there were 260 (73.9%) patients with ischaemic stroke, 38 (10.8%) with intracerebral haemorrhage and 54 (15.3%) with transient ischaemic attack (TIA). One hundred and seventy-two patients were admitted before and 180 after AST introduction. There were 70 AST calls from January to May 2005. Baseline characteristics of both groups were similar. Between the two groups, the median (Q1,Q3) time from door to CT scan was significantly reduced from 104 (60,149) to 82 (40,132) minutes. The LOS was significantly reduced from 6 (3,9) to 3 (2,7) days. There was no significant impact on mortality. CONCLUSION: The introduction of AST has reduced the time from door to brain CT scan. This is an important finding as the window period for thrombolysis is short and early diagnosis is crucial.     

Economic impact of crisis intervention in emergency psychiatry: a naturalistic study

OBJECTIVE: This is a naturalistic study comparing the outcomes of all emergency psychiatric interventions in the Hospital Center of Luxembourg during two periods of six months each, before and after the introduction of a crisis intervention program. The aim of the study was to investigate the clinical and economic impact of crisis intervention on psychiatric emergency admissions. METHODS: All subjects admitted to the emergency psychiatric unit during the two study periods were considered for participation. Data were collected retrospectively and comparisons were made between patients before (September 1, 2001 to February 28, 2002) and after (September 1, 2002 to February 28, 2003) crisis intervention programs were established. RESULTS: A comparison between the two patient groups demonstrated a significant decrease in the rate of voluntary hospitalizations after crisis intervention, and a significant increase in the number of patients with subsequent outpatient consultations. The cost increase due to ambulatory follow-ups was widely compensated for by the cost decrease due to hospitalization avoidance. CONCLUSIONS: These preliminary findings suggest that crisis intervention leads to a shift from hospitalization to outpatient psychotherapeutic management in emergency psychiatric services, which has a significant economic impact.     

Mitoxantrone as induction therapy in aggressive relapsing remitting multiple sclerosis: a descriptive analysis of 100 consecutive patients

INTRODUCTION: On the basis of the French and British (FB) MS Trial, Mitoxantrone (MITOX) was approved by the AFSAPPS in October 2003 in patients with aggressive multiple sclerosis (MS), given as induction therapy monthly for 6 months (ELSEP). We report an observational study of 100 aggressive relapsing remitting (RR) MS patients treated by induction therapy with MITOX and followed up to 5 years. METHODS: One hundred patients with aggressive RR MS received an induction therapy with MITOX 20 mg monthly combined with methylprednisolone 1 g for 6 months. MRI data within 12 months before and 6 months after MITOX induction were collected (mean cumulative dose 65 mg/m2). Clinical evaluation was performed every 6 months and data (relapses and EDSS scores) were prospectively recorded in the EDMUS Database. After MITOX, a maintenance therapy was given to 57 patients (MITOX every 3 months: 21; Interferon beta: 13; Azathioprine: 14; Methotrexate: 7; Glatiramer acetate: 2). The mean follow-up period was of 3.8 years. RESULTS: Patients were treated at a mean age of 27 +/- 9 years after 5 +/- 3 years of MS duration. Within the 12 months preceding MITOX onset, the annual relapse rate (ARR) was 3.2, the mean EDSS increased by 2.2 +/- 1 points (to a score of 4 at M0), 87 patients worsened by 1 point EDSS or more and 85 percent of patients had Gd enhancing lesions on MRI. During the 12 months following MITOX onset, the inflammatory activity of the disease dropped dramatically with a reduction of the ARR by 91 percent whereas 76 percent of patients were free of new relapse and MRI activity was reduced by 89 percent. In addition, the mean EDSS decreased by 1.2 points (p<10-6) and 60 percent of patients improved by 1 point EDSS or more. At a longer term, the reduction of the ARR was confirmed (0.28-0.37 up to 5 years) and the median time to the first relapse was 2.8 years. A significant improvement of disability was maintained until 4 years and got back to the initial level at year 5. The ARR was significantly lower (0.09) for patients treated with MITOX every 3 months as maintenance therapy than for patients treated by other disease modifying therapies (0.33-0.39) or not (0.43) after the induction. Three patients presented an asymptomatic decrease of the left ventricular ejection fraction under 50 percent, reversible in one case. CONCLUSION: MITOX as induction therapy monthly for 6 months was safe and had a rapid and strong impact on the inflammatory process and on the evolution of disability. The drug might be a good candidate as induction therapy followed by a maintenance therapy in patients with aggressive MS.     

Impact of a specialized early intervention service for psychotic disorders on patient characteristics, service use, and hospital costs in a defined catchment area.

OBJECTIVE: To evaluate the impact of a new early intervention service for first-episode psychosis on patient characteristics, service use, and hospital costs. METHOD: We examined clinical records of all first admissions to hospitals of patients diagnosed with first-episode psychoses (nonaffective) over a 3-year period before and after the introduction of an early intervention service, the Prevention and Early Intervention Program for Psychosis (PEPP), in a defined catchment area. We examined demographic, clinical, and service use indices covering a 2-year period subsequent to the index admission for each patient. RESULTS: Patients in the post-PEPP phase were significantly younger (P < 0.01), were more often male (P < 0.05), and were less likely to be admitted to hospital with an involuntary status (P < 0.05) or with injuries (P < 0.05) at the time of their first hospital admission. Over the 2 years following the initial admission, post-PEPP patients had significantly fewer admissions to a regular psychiatric service (P < 0.001) and made significantly fewer visits to the hospital emergency department (P < 0.01). There was a significant mean reduction in costs per case of regular hospital bed use ($1028.49, SD 528.02, compared with $792.28, SD 528.02; P < 0.01) and emergency visits ($519.18, SD 353.79, compared with $353.79, SD 345.0; P < 0.01). Time series analyses followed by Chow tests failed to confirm that these cost changes could be attributed specifically to the introduction of an early intervention service. CONCLUSION: Introduction of a specialized early intervention program may be beneficial to patients and to the health care system. To evaluate the cost-benefit ratio of early intervention services, longer term and more detailed data may be required.     

Newly diagnosed psychogenic nonepileptic seizures: health care demand prior to and following diagnosis at a first seizure clinic

Patients with psychogenic nonepileptic seizures (PNES) are heavy users of emergency and nonemergency health care. We performed a 1-year prospective audit of use of a group of PNES-related health care items in patients with newly diagnosed (mean duration: 7.3 months) PNES from PNES onset to diagnosis and from diagnosis to 6 months postdiagnosis. Twenty-eight patients (20 women, age: 34±16 years) were responsible for 14 general practitioner home visits, 31 ambulance calls, 34 emergency department visits, 21 hospital admissions (66 inpatient days), 8 MRI scans, 24 CT scans, 2 standard EEGs, 28 short video EEG recordings, and 5 ambulatory EEG recordings. In the 6 months following diagnosis, there were 2 emergency department visits (94.1% reduction), no hospital admissions (100% reduction), 2 ambulance calls, no general practitioner visits, 1 MRI scan, and no CT scans or EEGs. The immediacy of this marked health care demand reduction suggests that the relationship between presentation of diagnosis and health care demand reduction is causal.     

Month of Birth,a Risk Factor for Violent Behaviour in Suicidal Patients Admitted in Emergency?

Although there are numerous publications on the existing link between month of birth and suicide, only two studies focus on suicide attempts and auto-aggressive behavior. Research data suggest that month of birth is related to a variation of 5-HIAA in the cerebrospinal fluid, which correlates with violent behavior (VB). Therefore, the aim of this study is to search, for the first time, for a possible link between month of birth and the occurrence of VB in emergency, for patients admitted for a suicide attempt with medication. This is a 10 months prospective study among all the patients of the canton of Geneva, Switzerland, admitted in emergency for a suicide attempt with medication. During a 10 months study period we included 493 patients, of which 77 (15.62%) presented VB. Higher incidence of VB was found in subjects where born at the end of winter and the beginning of spring, with a maximum for April and a minimum for December. In spite of a relatively small number of subjects, it seems promising to study the occurrence of VB as a function of month of birth in patients admitted in emergency for a suicide attempt.

Assessing the impact of media guidelines for reporting on suicides in Austria: interrupted time series analysis

OBJECTIVE: Media guidelines for reporting on suicides are a widely used means of preventing imitative suicides, but scientific accounts of their impact on suicide numbers are sparse. This report provides an evaluation of the Austrian guidelines that were introduced in 1987 as a natural experiment. METHODS: The impact of the guidelines was tested by applying an autoregressive integrated moving average (ARIMA) model and a linear regression model. In addition to a nationwide evaluation, Austria was divided into three areas according to regional differences in coverage rates of the collaborating newspapers and the impact of the intervention was tested for each area separately. Main outcome measures were the overall annual suicide numbers, and the numbers of Viennese subway suicides that were exceptionally newsworthy for the mass media. In order to test intermediate impacts, also quantitative and qualitative changes in media reporting after the introduction of the guidelines were analysed. RESULTS: There was some evidence of a nationwide impact of the guidelines, calculated as a significant reduction of 81 suicides (95% confidence interval: -149 to -13; t = -2.32, df = 54, p <0.024) annually. This effect was particularly due to a significant reduction in the area with the highest coverage rates of the collaborating newspapers. Viennese subway suicides showed a highly significant level shift (t = -4.44, df = 19, p <0.001) and a highly significant trend change (t = -4.20, df = 19, p <0.001) after the introduction of the guidelines. These effects corresponded to significant changes in the quality and quantity of media reporting. CONCLUSIONS: The present results clearly support the hypothesis that the media guidelines have had an impact on the quality of reporting as well as on suicidal behaviour in Austria, and stress the importance of collaborating with nationwide, but also with regional media to achieve efficacy. Further research is needed to provide an international insight into this public health issue.     

Relationship of Carbamazepine Reduction Rate to Seizure Frequency During Inpatient Telemetry

Summary: To establish guidelines for medication reduction during inpatient telemetry, the records of 18 children and young adults with refractory partial seizures undergoing carbamazepine (CBZ) reductions during continuous video/EEG telemetry were reviewed. Six patients were receiving CBZ monotherapy, and 12 patients were treated with an additional antiepileptic drug (AED) maintained at baseline dosage during CBZ taper. Despite relatively rapid mean reductions in dosage of 44% by day 2 of taper, no patients experienced frequent repetitive seizures or status epilepticus (SE). Seizure rate during the entire CBZ reduction period correlated significantly with rate of drug reduction. Linear regression analysis showed drug reduction rate to be a good predictor of seizure rate. Fourteen patients experienced at least three seizures during CBZ taper. On the average, the third seizure occurred on day 5 of taper at a percentage of dose seduction of 79%. In 8 patients, CBZ concentrations were measured both before taper and ≤24 h after the third seizure. For these patients, seizure rate also correlated significantly with reduction in CBZ level. We conclude that manipulation of CBZ dose reduction rate is important in maximizing seizure frequency during telemetry and, in our patients, a relatively rapid rate of dose reduction was safe and effective in promoting seizure recordings.     

Prevalence of i.v. thiopental use in psychiatric emergency settings in Japan

Aim:  Because i.v. barbiturates such as thiopental carry the risk of apnea and laryngeal spasm in asthmatic patients, reducing the use of barbiturate in emergency situations is important. The purpose of the present study was therefore to investigate the prevalence of i.v. thiopental as a choice of sedation in behavioral emergency settings, we conducted a cross-sectional multicenter study.
Methods:  Psychiatric emergency departments of seven hospitals were studied during a 4-month period. Patients with a score >15 on the Excited Component of the Positive and Negative Syndrome Scale (PANSS-EC) who received i.v. medication were included in the study. Drugs were chosen according to the Japanese guidelines, in which the first injection was either haloperidol or benzodiazepine in accordance with clinical requirements. A second injection, which was the opposite drug to the first injection was administered as needed. Only when excitement obviously increased following the first injection, which was considered uncontrollable without thiopental according to expert experience, was thiopental given as a second injection. A total of 137 patients were included. The mean age was 40.4 years (SD 13.1), and the rate of male gender, drug-naïve, and F2 (schizophrenia, schizotypal and delusional disorders) on the ICD-10 were 48.9%, 29.9%, and 65.7%, respectively.
Results:  The rate of patients treated with thiopental as a second injection was 8.0% ( n  = 11). All of the first injections in patients treated with thiopental were not haloperidol but benzodiazepines ( P  = 0.0072).
Conclusion:  Because this multicenter study has an epidemiological character, the prevalence of i.v. thiopental use in psychiatric emergency settings in Japan is considered to be 8.0%.     

Relapse of aggressive and disruptive behavior in mentally retarded adults following antipsychotic drug withdrawal predicts psychotropic drug use a decade later

BACKGROUND: Mental retardation is frequently associated with aggression toward self and others. Antipsychotic medications are frequently used as a major treatment of such aggression. However, national and state policies and guidelines are weighted toward stopping or decreasing the doses of these medications whenever possible, although exceptions are permitted. The purpose of this study was to determine if relapse during or after antipsychotic drug withdrawal in mentally retarded adults predicts continuing antipsychotic drug use an average of a decade later. METHOD: We report here on a 6- to 13-year (average 10-year) follow-up of 151 institutionalized mentally retarded adults. During the period 1990-1997, the subjects had been prescribed antipsychotic medications to treat maladaptive behaviors, primarily consisting of aggression, disruptive/destructive behaviors, or a combination of these. We compared subjects' psychotropic medication profiles in 2003 as they related to outcome during the earlier period. Our goal was to determine if rapid relapse (a clinically significant increase in maladaptive target symptoms, beginning 3 months or less after antipsychotic drug termination or dosage reduction, that was reversed by antipsychotic drug reinstitution or dosage increases) during or after routine withdrawal of an antipsychotic predicted psychotropic drug use in 2003. RESULTS: For those individuals successfully withdrawn from antipsychotic medications, 66.3% (55/83) were still psychotropic drug free in 2003. For those who rapidly relapsed during the period 1990-1997 following antipsychotic drug withdrawal or dosage decreases, only 9.0% (5/55) were psychotropic medication free in 2003. CONCLUSION: These observations support policies and guidelines indicating that attempts to stop treatment with antipsychotic medications in mentally retarded individuals are worthwhile. However, the results also indicate that eventual discontinuation of antipsychotic medications in institutionalized mentally retarded adults who have previously relapsed upon such withdrawal is unlikely to be successful. Rigid adherence to drug withdrawal policies and guidelines in such individuals should be reconsidered.     

Major depressive disorders and psychiatric emergencies: a naturalistic study on crisis intervention relevance]

OBJECTIVE: This retrospective study aimed to evaluate the impact of introducing crisis intervention patterns in the emergency unit of a general hospital on the number of admissions and outpatient follow-ups for patients with major depressive disorder. METHOD: The study included all patients with major depressive disorder (DSM-IV criteria) who visited the psychiatric emergency unit in a general hospital during two 8-month periods: before (425 patients) and after (436 patients) crisis interventions were introduced. RESULTS: After crisis interventions were introduced, the voluntary admission rate decreased significantly (from 17.9% to 12.4%), while the number of outpatient follow-ups increased (from 82.1% to 86.2%). Borderline personality disorder was associated with a significant reduction of the admission rate (27.8% against 38.2%), while the admission rate for patients with depressive disorder with psychotic features did not decline after crisis interventions. Crisis interventions were more effective on women. CONCLUSIONS: These outcomes suggest the relevance of crisis intervention in psychiatric emergency settings to improve the management of patients with major depressive disorder. Crisis intervention fosters outpatient multimodal follow-up rather than admission in a psychiatric setting.     

Vagus nerve stimulation in patients with catastrophic childhood epilepsy, a 2-year follow-up study.

PURPOSE: To establish the long-term efficacy and tolerability of vagus nerve stimulation (VNS) in children with a Lennox-like syndrome. METHOD: This study was a longitudinal observational prospective cohort analysis. Baseline: 6 months. Follow-up: 24 months. Screening (baseline and every 6 months): MRI (baseline only), EEG, neuropsychological evaluation, ECG and blood sampling for antiepileptic drug levels. Nineteen children are included. RESULTS: A seizure frequency reduction of 20.6% was found at the end of the follow-up period. No relationship was detected between the length of the stimulation period and the reduction in the seizure frequency. 21% of the patients showed a reduction in seizure frequency of 50% or more. The seizure severity showed improvement in the first 12 months of treatment. The largest seizure reduction was found in the patients with highest frequency of background activity at the baseline EEG. Neuropsychological findings: no negative impact on behaviour, moderate improvement in function, behaviour and mood. Largest seizure reduction was found in the group with the highest baseline mental function. The scores for mental age improved independently of the seizure control. Twelve patients (63%) experienced minor side effects, which subsided after 1 month. CONCLUSION: (1) There was a significant reduction in seizure frequency and severity. (2) No serious side effects were recorded. (3) No negative effects on cognition or quality of life were apparent. (4) Patients with highest baseline mental functioning showed the highest seizure reduction. (5) Those patients with less disturbed EEG (high background activity and less interictal epileptic activity) showed the highest seizure reduction.     

Receiving guideline-concordant pharmacotherapy for major depression: impact on ambulatory and inpatient health service use.

OBJECTIVE: This study aimed to determine the associations between guideline-concordant pharmacotherapy for depression and the use of health services in the year following diagnosis. METHOD: This population-based, retrospective cohort study examined Quebec drug plans between 1999 and 2002. We included beneficiaries aged 18 to 64 years who were newly diagnosed with an episode of depression by primary care physicians and psychiatrists between October 1, 2000, and March 31, 2001, and who made at least one psychotropic pharmacy claim within 31 days of diagnosis. We defined guideline concordance as the receipt of recommended medication, starting dosage, and treatment duration as defined by the Canadian Network for Mood and Anxiety Treatments guidelines. We measured outcomes on use of ambulatory (number of visits to prescribing physician, other physicians, or emergency departments) and inpatient (hospitalization) services. RESULTS: There were 2742 patients (mean age 42 years; 64% female patients) who met the study criteria. Of the 2047 (75%) patients to whom an antidepressant was dispensed, 1958 (71%) received a recommended first-line medication, 1297 (63%) received a recommended starting dosage, and 304 (15%) received a recommended duration. According to the 3 criteria, only 8% were treated appropriately; 21% received benzodiazepines rather than antidepressants. There were 2 median visits (inferquartile range [IQR] 1 to 3) to prescribing physicians, 0 visits (IQR 0 to 1) to other physicians, and 0 visits (IQR 0 to 0) to emergency departments; 497 (18%) patients were hospitalized. In separate multivariate models for repeated measures, recommended first-line medication, dosage, and duration were associated with more prescribing physician visits. Recommended first-line medication reduced the odds of hospitalization. CONCLUSION: Guideline concordance was associated with more visits to prescribing physicians and lower odds of hospitalization.     

Electrical stimulation of the anterior nucleus of the thalamus for intractable epilepsy: a long-term follow-up study

PURPOSE: The anterior nucleus of the thalamus (ANT) modulates temporal lobe and hypothalamic activities, and relays information to the cingulate gyrus and entorhinal cortex. Deep brain stimulation (DBS) of the ANT has been reported to decrease seizure activity in a limited number of human subjects. However, long-term effect of chronic ANT stimulation on such patients remains unknown. We report long-term follow-up results in four patients receiving ANT stimulation for intractable epilepsy. METHODS: Four patients underwent stereotactic implantation of quadripolar stimulating electrodes in the bilateral ANT, guided by single-unit microelectrode recording. Electrode location was confirmed by postoperative magnetic resonance imaging (MRI). The stimulator was activated 2-4 weeks following electrode insertion; initial stimulation parameters were 4-5 V, 90-110 Hz, and 60-90 micros. Seizure frequency was monitored and compared with preimplantation baseline frequency. Intelligence quotient (IQ) test and auditory P300 response were performed before and after implantation of electrodes. RESULTS: Four patients (one man with generalized seizures, and three women with partial seizures and secondary generalization) aged 18-45 years old were studied with mean follow-up period of 43.8 months. The four patients demonstrated a sustained effect of 49% (range, 35-76%) seizure reduction to ANT stimulation. Simple insertion of DBS electrodes (Sham period, no stimulation) produced a mean reduction in seizures of 67% (range, 44-94%). One patient was seizure-free for 15 months with anticonvulsant medications. One patient had a small frontal hemorrhage and a second patient had extension erosion over scalp; no resultant major or permanent neurological deficit was observed. Preoperative IQ index and auditory P300 were not significantly different with those after electrodes implantation. CONCLUSIONS: Implantation of electrodes in the ANT and subsequent stimulation is associated with a significant reduction in seizure frequency. However, our study could not differentiate whether the implantation itself, the subsequent stimulation or postimplantation drug manipulation had the greatest impact. These experimental results prompt further controlled study in a large patient population.     

Efficacy and tolerability of levetiracetam in patients with therapy-resistant epilepsy and learning disabilities.

INTRODUCTION: The purpose was to evaluate the effects of levetiracetam (LEV) in routine therapy in learning disabled patients with therapy-resistant epilepsy. METHODS: In an open observational add-on study design, 46 patients (residents of the Bethel Epilepsy Centre) with severe therapy-resistant epilepsy and different degrees of learning disabilities, who were treated with LEV between its introduction in Autumn 2000 and February 2002, were evaluated retrospectively. Information on monthly seizure frequencies, seizure severity and psychiatric status was extracted from the current patient case records. A 3 months baseline and a 3 months LEV treatment period (after 3 months of titration) were compared. Responders were defined as having a 50% reduction in seizure frequency and being evaluated as good or very good in an ad hoc global clinical efficacy scale. When only one criterion was positive, a careful individual decision was made based on the impact on the patients' daily activities. RESULTS: The responder rate was 41.3% (34.8 for 50% seizure reduction). It was higher in focal and multifocal epilepsy as compared to symptomatic generalised epilepsy/Lennox Gastaut Syndrome (P<0.05). Antiepileptic response occurred in doses between 500 and 4000 mg/day. Changes in seizure severity were rare. Nine patients experienced positive psychotropic effects (mostly improved vigilance and mood); six of these patients had antiepileptic effects as well. Twelve patients had adverse effects, mostly mild; in three cases, however, more severe effects led to discontinuation. CONCLUSIONS: LEV is an effective and generally well-tolerated drug for this patient group, especially in focal and multifocal epilepsy.     

Diagnosis and treatment of injuries of the brachial plexus in our experience

The subject of the paper is an analysis of the pathomechanism of injuries and results of multispecialist diagnostic investigations and surgical treatment in 74 cases of traumatic brachial plexus injuries observed in a period of 5 years. The observations of the authors suggest the following conclusions: Direct injury to the brachial plexus requires emergency or delayed emergency surgical intervention. In indirect and secondary traumatic injuries of the plexus the best results are obtained by possibly early reconstructive operation carried out after establishing indications to surgical treatment. The optimal time for full diagnosis of brachial plexus injury and its surgical treatment is between 3 and 6 months after trauma. The full diagnosis of brachial plexus injury should include: radiological examination of the cervical spine with radiograms in flexion and extension (if necessary) and contrast investigations (myelography) of the vertebral canal for determining canal patency and cerebrospinal fluid changes and dynamics. Electromyography is one of the principal elements of the diagnostic procedures used for the localization of plexus damage and for evaluation of the return of function after surgery. It would be indicated to organize in Poland special hospital departments or centres for systematic diagnostic investigations and surgical treatment of patients with brachial plexus injury.     

The health economic implications of treatment with quetiapine: an audit of long-term treatment for patients with chronic schizophrenia.

This retrospective, case series audit assessed the clinical and health-economic impact of long-term treatment with quetiapine ('Seroquel'), a new atypical antipsychotic, in patients with chronic schizophrenia.The study design was of a case series format, comprising patients entered from one centre into the open-label extension of a multicentre 6-week efficacy study. Twenty-one patients (15 male, six female; mean age 39 years) were studied, of whom 17 (81%) had been rated as 'partially responsive' to previous antipsychotics. Data on hospitalisations and information on symptoms were collected retrospectively for the 12 months before quetiapine treatment was initiated and for the 12 months after.Quetiapine was effective in reducing psychotic symptoms with mean BPRS scores reducing significantly, from 38 to 21 (P < 0.005). Motor function was also significantly improved with mean Simpson scale scores reducing from 15 to 12 (P < 0.005). Average inpatient days were reduced by 11% in year two (97 compared with 109 days) while the overall costs of treatment, including drug costs, fell by 5% (I pound sterling 20,843 to I pound sterling 19,827).Four patients had been hospitalised for longer than 5 years before starting quetiapine; these chronically institutionalised patients remained in hospital, despite improved clinical outcomes (mean BPRS scores after treatment of 34, compared with 43 before), for the full 12 months of quetiapine treatment. Were the data from this audit to be re-analysed excluding these four patients then average inpatient days would have been reduced by 33% (45 to 30 days) and overall cost of treatment by 19% (I pound sterling 8617 to I pound sterling 7011).This audit suggests that treatment with quetiapine over this 1-year period was associated with both clinical improvements and a decreased usage of inpatient services. The reduction in hospitalisation costs would appear to compensate for the increased cost of drug treatment. Significantly, potential savings appear to be greatest for those patients with a 'revolving door' pattern of repeated readmission.     

Sertraline and fluoxetine: safe treatments for children and adolescents with epilepsy and depression

OBJECTIVE: Depression is frequent, underdiagnosed, and untreated in people with epilepsy. The lack of treatment is partially explained by the concerns over the proconvulsive effects of psychoactive drugs. There are few studies on the effects of selective serotonin reuptake inhibitors (SSRIs) in adults with epilepsy and none in children. The main purpose of the present study was to analyze the impact of SSRIs on the severity and frequency of seizures in children and adolescents with epilepsy and major depressive disorders. In addition, we also evaluated the efficacy of SSRIs in the treatment of depressive symptoms and side effects other than seizure aggravation. METHODS: Monthly frequency of seizures was recorded in the 3-6 months preceding the introduction of SSRIs. According to the criteria proposed by A.M. Kanner, A.M. Kozak and M. Frey (Epilepsy Behav 2000;1:100-5), a positive correlation between introduction of SSRIs and seizure worsening should be considered in the following circumstances: (1) occurrence of de novo generalized tonic-clonic (GTC) seizures; (2) recurrence of GTC seizures following a period of at least 1 year without such episodes; and (3) increase in monthly seizure frequency compared with that reported before introduction of SSRIs. Seizure worsening was considered as probably caused by an SSRI when the increase in monthly frequency occurred in a period up to 3 months after the beginning of SSRI use. RESULTS: Thirty-six children with epilepsy had a depressive disorder. Seizures worsened in two patients. Among this group of patients with depression, all had an improvement in their depressive symptoms. One patient taking fluoxetine had a facial rash and one patient taking sertraline had gastrointestinal disorders. These conditions improved, with total remission, when fluoxetine was replaced with sertraline and vice versa. CONCLUSION: In this sample of children and adolescents with epilepsy and depressive disorders, we observed that SSRIs are a good therapeutic option, considering their efficacy in remission of depressive symptoms, their few adverse effects, and their maintenance of satisfactory seizure control. Treatment of depression should be considered relevant in the treatment of patients with epilepsy.     

Diagnosing psychotic disorders in the emergency department in the context of substance use

OBJECTIVE: For patients who are actively using a substance and experience psychotic symptoms, determining whether the psychotic symptoms are due to a primary psychotic disorder or are substance induced is challenging, especially in emergency departments, where historical information is limited. This study examined the accuracy and subsequent treatment implications of emergency department diagnoses among substance-using patients who were having their first psychotic episode. METHODS: Emergency department diagnoses for 302 patients were compared with best-estimate longitudinal diagnoses (BELDs) based on research assessments at three time points (baseline, six months, and 12 months). RESULTS: Of the 223 patients whose symptoms were diagnosed in the emergency department as a primary psychotic disorder, one-quarter were determined by the BELD to have substance-induced psychosis or no psychosis. Overall, the diagnostic agreement was only fair (kappa=.32). Patients with an emergency department diagnosis of primary psychosis were significantly more likely than those with an emergency department diagnosis of substance-induced psychosis to be hospitalized, started on antipsychotic medication, and referred to mental health services instead of treatment for substance use (p<.001). Patients given an emergency department diagnosis of primary psychosis who were found by the BELD to have substance-induced psychosis or no psychosis were significantly more likely to be treated for a psychotic disorder rather than for substance-induced psychosis (p<.001) CONCLUSIONS: Clinicians in psychiatric emergency departments appear to have a tendency to attribute psychotic symptoms to a primary psychotic disorder rather than to concurrent substance use. Given that the diagnosis has significant implications for future management, it is important to improve diagnostic approaches in the emergency department.
