Imprisonment, alcohol dependence and risk of delusional disorder: a cross-sectional study.

BACKGROUND: Compared to the general population, an excess of psychotic illnesses, major depression and dependence disorders among prisoners has been reported. However, the impact of prison on detainees' psychopathology has rarely been studied. OBJECTIVE: To determine the mental disorders liable to develop or regress on entry into prison and over time. METHOD: Two samples of French prisoners detained in local prisons were interviewed using the same methodology. The first sample consisted of 267 new arrivals. The second was a random sample of 450 prisoners. Diagnoses were assessed using a thorough methodology: each prisoner was interviewed for approximately 2 hours by two clinicians. One of the clinicians used a structured clinical interview, which generates DSM IV diagnoses (MINI plus v 5.0); the second completed the procedure with an open clinical interview. The final DSM IV diagnoses were obtained as a consensus between the two approaches. Multilevel logistic regressions were used to take into account potential confounders. RESULTS: Prevalence rates of mental disorders were substantially higher in prison even for the sample of newcomers (major depression disorder: 24.7%, substance dependence: 17.6% and schizophrenia: 4.1%). Alcohol dependence disorder was significantly more frequent in the sample of newcomers (OR 1.84 [1.01-3.51]). No significant difference was evidenced between samples for substance dependence disorder. Psychotic disorders were significantly less frequent at entry into prison, particularly delusional disorder (OR 0.29 [0.08-0.98]). CONCLUSION: This study shows the contrasted potential effects of prison on psychopathology: alcohol dependence disorders were significantly more frequent for the newcomers, while the frequency of delusional disorders was lower. This evidence is arguing in favour of the validity of the old concept: prison psychosis. Moreover, prisoners should receive relevant help from clinicians to cope with these disorders.

Hospital cost of Clostridium difficile infection including the contribution of recurrences in French acute-care hospitals.

BACKGROUND: The impact of Clostridium difficile infection (CDI) on healthcare costs is significant due to the extra costs of associated inpatient care. However, the specific contribution of recurrences has rarely been studied. AIM: The aim of this study was to estimate the hospital costs of CDI and the fraction attributable to recurrences in French acute-care hospitals. METHODS: A retrospective study was performed for 2011 on a sample of 12 large acute-care hospitals. CDI costs were estimated from both hospital and public insurance perspectives. For each stay, CDI additional costs were estimated by comparison to controls without CDI extracted from the national DRG (diagnosis-related group) database and matched on DRG, age and sex. When CDI was the primary diagnosis, the full cost of stay was used. FINDINGS: A total of 1067 bacteriological cases of CDI were identified corresponding to 979 stays involving 906 different patients. Recurrence(s) were identified in 118 (12%) of these stays with 51.7% of them having occurred within the same stay as the index episode. Their mean length of stay was 63.8 days compared to 25.1 days for stays with an index case only. The mean extra cost per stay with CDI was estimated at €9,575 (median: €7,514). The extra cost of CDI in public acute-care hospitals was extrapolated to €163.1 million at the national level, of which 12.5% was attributable to recurrences. CONCLUSION: The economic burden of CDI is substantial and directly impacts healthcare systems in France.

[Two years follow-up of a heroin users cohort treated with high dosage buprenorphine. Results of the SPESUB study (pharmacoepidemiologic follow-up of general practice Subutex)]. / Suivi à 2 ans d'une cohorte de patients sous buprénorphine haut dosage. Résultats de l'étude SPESUB (suivi pharmaco-épidémiologique du Subutex en médecine de ville).

BACKGROUND: Since February 1996, French GPs are allowed to prescribe high dosage buprenorphine for maintenance treatment of major opioid drug addiction. A prospective cohort of major opioid addicts was initiated in order to assess patient outcomes: follow-up, retention rate in treatment, drug use, intravenous injection and social situation evolution. METHODS: Each GP, known to be involved in drug user management, had to include the first 10 opioid drug addict patients to whom he prescribed high dosage buprenorphine, with a maximum inclusion period of 3 months. Patients were followed up for two years and a regular standardized information was collected (usual data on drug users and prescription modalities). RESULTS: Between May and July 1996, 919 patients (664 men and 255 women, mean age: 30 years) were included by 101 GPs. They had a long and serious history of drug addiction, important parallel consumption of cocaine, codeine and other illicit drugs and psychiatric problems (28% of definite problems and 45% of probable) and frequent hepatic conditions (hepatitis B: 23%, hepatitis C: 21%). Two years later, 55% of patients were still followed-up by the same GP and an additional 12% were followed by another GP or in a health care service (hospitalized or receiving methadone in a specialized centre). 13% were not followed, but GPs were able to describe their situation. 8% had been included by GPs who had dropped the study. Finally, 12% of patients were lost to follow-up. Among the 508 patients still followed-up by the same GP after 2 years, the substitution treatment rate was 84%. The dosage bracket had widened (inclusion: mean dosage=7.8 mg +/-4.5, minimum=0.8, maximum=28, median=8; after 2 years: mean=7.6 mg +/-5.4, minimum=0.4, maximum=28, median=8) and the duration of the prescription and dispensing had increased. Declaration of heroin intake in the previous month had fell from 40% to 11% and declaration of drug intake from 53% to 20%. Social situation had improved on average (housing conditions and work). There were 12 seroconversions for hepatitis B, 21 for hepatitis C and 4 for HIV. 14% of patients had declared intravenous injection of high dosage buprenorphine in the previous month. CONCLUSION: After two years of follow-up, 55% of patients were still followed-up by the same GP and an additional 12% was followed by another GP or in a health care service. Among patients still followed up by the same GP, a reduction of drug related harm (seroconversions for hepatitis B, hepatitis C and HIV) was observed.

[Use of a structured diagnostic interview to identify depressive episodes in an epidemiologic study: a posteriori internal validation]. / Utilisation d'un entretien diagnostique structuré pour identifier les épisodes dépressifs dans une étude épidémiologique: validation interne a posteriori.

BACKGROUND: During these last years, many structured and standardized diagnostic interviews have been developed in order to identify psychiatric disorders in a standardized way. These tools enable a systematic investigation of these disorders according to international classifications. Their main drawback is to be long. To assess the care of depression, we used a shorter and more simple tool: the Mini International Neuropsychiatric Interview (MINI) to identify depressive subjects. METHOD: The study was conducted in the Gazel cohort from the French National Electricity and Gas Company. A stratified sample of 2394 civil servants selected in order to over-represent depressive subjects was asked to answer to the MINI interview through a phone interview. An epidemiological and statistical analysis was performed to test the MINI internal validity: prevalence of depressive disorders using different threshold of diagnosis (number of symptoms required to identify someone as depressive), frequency of different symptoms, variability between investigators and potential biases. RESULTS: Respondents to the phone interview (1108 civil servants) had more often presented depression markers for the last 5 years. Prevalence of depressive episodes changed little when we varied the threshold of diagnosis and did not stress any threshold problem. The variability between investigators was important, but the estimation of prevalence remained stable when we excluded extreme rates of prevalence. The choice of a classification system affected the prevalence estimation. Using the Diagnostic and Statistical Manual of Mental Disorders (DSM IV) from the American Psychiatric Association, the prevalence of depressive episodes was lower and closer to the estimations shown in the literature than using the International Classification of Disease (ICD 10). Moreover, the stratification assigned very unbalanced weights to the stratification strata. By excluding depressive episodes observed in the stratum "control" (no depression "marker" from 1989 to 1994 in the database), the prevalence was very lower, whatever the classification was. Finally, factors which appeared linked to care of depression with the ICD definition remained the same when the DSM diagnosis definition was used, and relative risks were quite similar. CONCLUSION: The MINI appears to be a short and simple tool, suited to the epidemiological studies. This analysis does not highlight any failure in the internal consistency of the MINI. The remaining question is what the MINI really measures, particularly comparing to a psychiatrist's diagnosis.

[Cross-sectional study of the prevalence of adjustment disorder with anxiety in general practice]. / Etude transversale de la prévalence du trouble de l'adaptation avec anxiété en médecine générale.

Although Adjustment Disorder (AD) is considered a marginal diagnostic category by many clinicians and researchers, all the rare studies undertaken in the last decades indicate that the prevalence of this disorder is high in psychiatric settings, but has never been investigated in general practice. The purpose of this study was to evaluate the current prevalence of Adjustment Disorders With Anxiety (ADWA) in primary care settings and to describe the characteristics of the population, nature of the stressors and management of the disorder by General Practitioners (GPs). This French study involved 78 random liberal GPs, in 7 distinct regions (Paris, Lille, Bordeaux, Rouen, Dijon, Castres and Compiègne). GPs had to register all the consecutive attenders over 18 years old. For each physician, the registration period was over when 200 patients were registered, or 10 days of consultation were completed, or when 5 MINI had been performed. The average study period was 10 days per physician. At the first stage, they selected all the patients with psychological complaints, which were eventually associated to physical complaints. At the second stage, only the patients whose complaints were linked to a psychosocial stressor and without A1 and/or A2 DSM IV criteria for a Major Depressive Episode (MDE) were proposed the Mini International Neuropsychiatric Interview (MINI). The MINI is a brief structured clinical diagnostic interview that identifies the main axis-I DSM IV diagnoses in about 15 minutes. Before starting the study, all of the GPs participated in an intensive course on AD criteria recognition and were trained to use the MINI. The GPs registered a total of 7,759 consecutive patients. Twenty-two per cent (n = 1,719) of the patients reported psychological complaints, associated or not to physical complaints. Among them, 49% (n = 844) linked their complaints to identifiable psychosocial stressors. About half of the latter (n = 450) coded positive to A1 and/or A2 criteria for MDE. At the end, a total of 314 patients agreed to complete the MINI. Among the 1,719 patients with psychological complaints, the prevalence of ADWA eventually associated to other psychiatric disorders was 9.2%. The prevalence of "pure" ADWA was 4.5%. When considering the whole population of consecutive patients in primary care settings, the prevalence of pure ADWA was 1.0%. Patients suffering from pure ADWA were mostly women (66.7%), young patients (mean age: 42 years), with a professional activity. Patients had a psychiatric disorder history in 53.8% of the cases (mostly anxiety disorder). The main life events cited as being responsible for the disorder were work-associated problems (23.1%), followed by family illness (9.0%) and serious personal illness or accident (7.7%). The average duration of the disorder was 2.32 months. In 91% of the cases, GPs estimated that the patient required a pharmacological or psychological treatment. In most cases, they treated the patients with drug therapy (74.0%) associated with psychological support (counselling or psychotherapy, 76%). Anxiolytic agents were usually prescribed (64.9%), followed by antidepressants (10.8%) and hypnotics (8.1%). In conclusion, this first prevalence study of ADWA in general practice demonstrates that this disorder is frequent in primary care. It seems to be more present in patients who are of working age, especially women. ADWA would thus seem to preferentially affect active subjects. In most cases, GPs treat their patients with both psychological support and drug therapy. Anxiolytic is the elicited treatment of this disorder.

Adjustment disorder with anxiety in old age: comparing prevalence and clinical management in primary care and mental health care.

PURPOSE: Adjustment disorder with anxiety (AjD-A) is a common cause of severe anxiety symptoms, but little is known about its prevalence in old age. METHODS: This cross-sectional study examined the prevalence of AjD-A in outpatients over the age of 60 who consecutively consulted 34 general practitioners and 22 psychiatrists during a 2-week period. The diagnosis of AjD-A was obtained using the optional module for diagnostic of adjustment disorder of the Mini International Neuropsychiatric Interview (MINI). The study procedure also explored comorbid psychiatric conditions and documented recent past stressful life events, as well as social disability and current pharmacological and non-pharmacological management. RESULTS: Overall, 3651 consecutive subjects were screened (2937 in primary care and 714 in mental health care). The prevalence rate of AjD-A was 3.7% (n=136). Up to 39% (n=53) of AjD-A subjects had a comorbid psychiatric condition, mostly of the anxious type. The most frequently stressful life event reported to be associated with the onset of AjD-A was personal illness or health problem (29%). More than 50% of the AjD-A patients were markedly to extremely disabled by their symptoms. Compared to patients who consulted psychiatrists, patients who were seen by primary care physicians were older, had obtained lower scores at the Hamilton Anxiety Rating Scale, benefited less frequently from non-pharmacological management and received benzodiazepines more frequently. CONCLUSIONS: AjD-A appears to be a significantly disabling cause of anxiety symptoms in community dwelling elderly persons, in particular those presenting personal health related problems. Improvement of early diagnosis and non-pharmacological management of AjD-A would contribute to limit risks of benzodiazepine overuse, particularly in primary care settings.
