Simit epidemiological multicentric study on hospitalized immigrants in Italy during 2002

The aim of this article is to retrospectively evaluate the patient characteristics and the most common infectious diseases in immigrant patients hospitalized in 46 Italian infectious disease clinics during 2002. The main Italian infectious disease clinics were invited to fill in a questionnaire that regarded the number and type of hospital admissions, the country of origin, and demographic features (age, sex, and resident state) of immigrants. A total of 46 clinics including 2255 patients participated in the study. Most patients were men (63%) with an age between 16 and 40 years (63.4%) covered by the National Health Service (71%) and coming from Africa (44.3%). The main infectious diseases observed were: 378 (16.76%) cases of HIV infection, 303 (13.43%) cases of tuberculosis diseases, 282 (12.5%) cases of various forms of viral hepatitis, 177 (7.84%) cases of respiratory diseases, and 196 (8.69%) gastrointestinal diseases. Tropical diseases found were 134 (5.94%) including 95 cases of malaria (70.9%). In conclusion, a broad range of diseases was noted in immigrants which were directly correlated with conditions of poverty. Only a few tropical diseases were diagnosed and therefore the immigrant should not be considered as an infectious disease carrier.     

Relationship between country of birth and psychiatric admissions in Western Australia

The rates of admissions in 1976–78 to all hospitals in Western Australia, both psychiatric and non-psychiatric, of patients with a primary psychiatric diagnosis were analysed specifically for country of birth and whether they lived in Perth or in country areas. Eastern European migrants had the highest hospitalization rates, and Southern European migrants the lowest. Rates for schizophrenia were high in the Eastern Europeans, and for alcoholism low in Southern European and Asian females and high in Northern European males. The United Kingdom migrants were most like the Australian born in regards to admission rates, diagnostic composition, and in the distribution of hospitalization patterns between psychiatrists and non-psychiatrists. Women, especially Southern European, in the country areas are at special risk to be admitted for neurosis/personality disorder.     

Poor mental and physical health differentially contributes to disability in hospitalized geriatric patients of different ages

OBJECTIVE: To evaluate the relationship between depressive symptoms, cognition and somatic diseases on functional status of geriatric patients at hospital discharge. METHOD: Patients 65+ years consecutively admitted to the acute care geriatric ward of the Internal Medicine Department I, Civil Hospital of Brescia, Italy, from February 1998 to December 2000 (n = 830) were examined. Functional disability was defined as need of physical assistance in at least one of the basic Activities of Daily Living (ADL). The Greenfield Index of Disease Severity (IDS) and the Geriatric Index of Comorbidity (GIC) were used to measure number and severity of diseases. The Mini-Mental State Examination (MMSE) assessed cognitive status and the Geriatric Depression Scale (GDS) measured depressive symptoms. RESULTS: Prevalence of functional disability at discharge was 29.3% in the younger age group (65-74 years) and 55.2% in the older age group (75+ years). Using logistic regression models, older age, poorer cognitive status, and depressive symptoms were independently associated with functional disability in the younger and older age group, respectively. Additionally cognitive impairment and depressive symptoms showed an additive association with disability, especially in younger patients, while comorbidity was correlated with functional status only in the oldest old, in particular among those who were cognitively impaired. CONCLUSION: Functional disability after acute hospitalization is highly prevalent in geriatric patients. Depressive symptoms, comorbidity, and cognitive impairment often coexist, interact and are differentially associated with function depending on age. Considering that depressive symptoms are a modifiable problem, their detection in hospital settings may help clinicians in targeting subjects at high risk of functional disability.     

The cost-effectiveness of anorexia nervosa treatment

OBJECTIVE: Anorexia nervosa (AN) is an expensive-to-treat illness with a high mortality rate. Some health care systems have limited the amount of treatment provided for AN despite the lack of clearly documented efficacy for these limited-intensity approaches. One method that can inform decisions about AN treatment is cost-effectiveness analysis. METHOD: Cost-modeling analysis was used to estimate the incremental cost-effectiveness of AN treatment. Modeling was chosen given the lack of primary data on costs and outcomes in AN treatment. Data for age of onset, life expectancy, and disease-associated mortality were taken from the literature. The costs of treatment used in the analysis were those in use at the University of Minnesota. RESULTS: Assuming an approach consisting of inpatient weight restoration, followed by treatment of gradually diminishing intensity (partial hospitalization, then outpatient psychotherapy plus medication management), incremental cost-effectiveness ratios were calculated and compared with a limited intensity, "usual care" model. These assumptions yielded a cost per year of life saved of 30,180 dollars. DISCUSSION: Relative to many other medical interventions, the comprehensive treatment of AN appears to be quite cost-effective in terms of cost per year of life saved. Such data may have an impact on payer decisions and underscore the serious nature of AN.     

Respiratory syncytial virus infection--risk factors for hospital admission: a case-control study

Most infants are infected with respiratory syncytial virus (RSV) during the first 2 y of life. The majority have only a mild upper respiratory tract infection, but 1-2% develop a more severe illness and are admitted to hospital. AIM: To carry out a study of risk factors for hospital admission because of RSV infection in Denmark in children aged less than 2 y of age. METHODS: The study population included all 1252 children admitted to hospital with verified RSV infection in two Danish counties during the 5-y period 1990-1994. The investigation comprised a retrospective case-control study with five matched controls per case. In a multivariate analysis the risk factors included medical and demographic variables, and in infants <3 mo of age at hospitalization, two aspects of innate immunity: mannose-binding lectin (MBL) concentration and maternal RSV serum antibody titre, measured on eluates from stored dried blood from the infants' 4th day of life. The effect of each risk factor is expressed as an odds ratio, corresponding to the relative risk of being a case rather than a control if the risk factor is present. RESULTS: The following independent risk factors were identified: age, sex, month of birth, gestational age, birthweight, presence of a sibling, up to 5 y older than the case, and maternal smoking during pregnancy. There was a marginal effect of maternal RSV antibody levels, but no effect of neonatal serum MBL concentration or of crowding in the household. CONCLUSIONS: Ninety percent of cases and 80% of controls had one or more risk factors. Even though several factors were found to increase the risk for hospitalization for RSV disease, all the effects were small and no single specific factor could be identified to explain the hospitalization of the minority of children with RSV infection.     

First results from an intensified monitoring system to estimate drug related hospital admissions

AIMS: An intensified monitoring system was set up to identify drug related hospital admissions and estimate population-based incidences for commonly prescribed medications. METHODS: Pharmacovigilance-centres systematically screened nonelective admissions to emergency rooms or departments of internal medicine for drug related hospitalizations (DRH). Clinical pharmacologists used standardized causality assessment. Service areas of each acute care hospital were defined by 5 digit postal codes that covered 60% of all admissions. Drug dispensing information was available through claims processed by regional pharmacy computing centres. Quarterly incidences were estimated by dividing the number of events by the number of treated patients. RESULTS: 435 DRHs were reported during five quarters. The incidence of ADRs leading to admissions varied for specific drug groups from 1.5/10 000 treated patients to 24/10 000. Quarterly variation of incidences was moderate except for insulin and calcium antagonists. 95% confidence intervals overlap for all quarters within each group. Incidences are sensitive to changes in the definition of the source population. CONCLUSIONS: Our pharmacovigilance monitoring system allows comparisons of population-based incidences of drug-related hospitalizations among drugs and over time. It provides important information for risk management and monitoring outcomes of pharmaceutical quality management programmes.     

Sources of coercive behaviours in psychiatric admissions

OBJECTIVE: Coercion during psychiatric admissions has been a topic of debate for many years. Although there has been considerable research on patients' perceptions of coercion, there has been no work on who places pressures on patients to be admitted. METHOD: This article integrates interview data from interviews with patients, admitting staff and family and friends to describe the pressures brought to bear on patients to be admitted. RESULTS: Health-care professionals appear to be the most important source of pressures on patients, and to have the most impact on patients' perceptions of coercion. However, there are differences in type of pressure, and the pressures used by family and friends appear to have the most longstanding impact. CONCLUSION: Legal and clinical efforts to reduce the level of coercive pressures on patients need to recognize the importance of mental-health professionals, including especially those who are not legally mandated to participate in the admission process.     

Emerging homosexual conduct during hospitalization among chronic schizophrenia patients

OBJECTIVE: The study investigated the emerging homosexual conduct during hospitalization among chronic schizophrenia patients. METHOD: We interviewed 55 male and 58 female chronic schizophrenic patients to investigate their sexual history before and after admission. Those patients were under 45 years old, without significant deteriorated cognitive function, lived in a homogeneous gender chronic ward and did not demonstrate homosexual behaviour before admission. RESULTS: Nineteen patients (16.8%) reported having homosexual conducts during hospitalization. Their characteristics were: 1) having sexual experience before admission; 2) with younger age at first sexual experience; and 3) female patients having more sexual partners before admission. CONCLUSION: A significant proportion of patients need a sexual outlet during long-term hospitalization. Sexual education and counselling are greatly needed.     

In-patient suicide in psychiatric hospitals

OBJECTIVE: In-patient suicides continue to be a matter of concern in hospital psychiatry. In-patients at risk for suicide need to be identified. METHOD: In-patient suicides in two psychiatric hospitals were assessed over a time-span of 8 years. Cases were detected by comparing police suicide data with the hospitals' admission and discharge records. Further information was then gathered from patients' records. RESULTS: During the period under investigation 44 in-patients committed suicide, the majority of them being diagnosed with affective disorders (45.4%) or schizophrenia (27.3%). The most commonly used method was 'jumping in front of a vehicle' (34.1%); 79.5% were treated in an open ward at the time of their suicide, 15.9% in a locked unit. The majority of open ward suicides happened outside the hospital; 39.4% of patients had left the ward without giving notice. CONCLUSION: Additional cautionary measures are warranted especially for patients in open wards.     

Case-based Surveillance of Influenza Hospitalizations during 2004�C2008, Colorado, USA

Colorado became the first state to make laboratory-confirmed influenza-associated hospitalizations a case-based reportable condition in 2004. We summarized surveillance for influenza hospitalizations in Colorado during the first 4 recorded influenza seasons (2004–2008). We highlight the similarities and differences among influenza seasons; no 2 seasons were entirely the same. The 2005–06 influenza season had 2 distinct waves of activity (types A and B), the 2006–07 season was substantially later and milder, and 2007–08 had substantially greater influenza B activity. The case-based surveillance for influenza hospitalizations provides information regarding the time course of seasonal influenza activity, reported case numbers and population-based rates by age group and influenza virus type, and a measure of relative severity. Influenza hospitalization surveillance provides more information about seasonal influenza activity than any other surveillance measure (e.g., surveillance for influenza-like illness) currently in widespread use among states. More states should consider implementing case-based surveillance for influenza hospitalizations.
