Impact of psychiatrists' qualifications on the rate of compulsory admissions.

Despite efforts to reduce coercion in psychiatry, involuntary hospitalizations remain frequent, representing more than half of all admissions in some European regions. Since October 2006, only certified psychiatrists are authorized to require a compulsory admission to our facility, while before all physicians were, including residents. The aim of the present study is to assess the impact of this change of procedure on the proportion compulsory admissions. All medical records of patients admitted respectively 4 months before and 4 month after the implementation of the procedure were retrospectively analyzed. This search retrieved a total of 2,227 hospitalizations for 1,584 patients. The overall proportions of compulsory and voluntary admissions were 63.9 % and 36.1 % respectively. The average length of stay was 32 days (SD ± 64.4). During the study period, 25 % of patients experienced two hospitalizations or more. The most frequent patients' diagnoses were affective disorders (30 %), psychotic disorders (18.4 %) and substance abuse disorders (15.7 %). Compared with the period before October 2006, patients hospitalized from October 2006 up were less likely to be hospitalized on a compulsory basis (OR = 0.745, 95 % CI: 0.596-0.930). Factors associated with involuntary admission were young age (20 years or less), female gender, a diagnosis of psychotic disorder and being hospitalized for the first time. Our results strongly suggest that limiting the right to require compulsory admissions to fully certified psychiatrists can reduce the rate of compulsory versus voluntary admissions.

Burden of bloodstream infection caused by extended-spectrum ß-lactamase-producing enterobacteriaceae determined using multistate modeling at a Swiss University Hospital and a nationwide predictive model.

OBJECTIVE: To obtain an unbiased estimate of the excess hospital length of stay (LOS) and cost attributable to extended-spectrum ß-lactamase (ESBL) positivity in bloodstream infections (BSIs) due to Enterobacteriaceae. DESIGN: Retrospective cohort study. SETTING: A 2,200-bed academic medical center in Geneva, Switzerland. PATIENTS: Patients admitted during 2009. METHODS: We used multistate modeling and Cox proportional hazards models to determine the excess LOS and adjusted end-of-LOS hazard ratio (HR) for ESBL-positive and ESBL-negative BSI. We estimated economic burden as the product of excess LOS and average bed-day cost. Patient-level accounting data provided a complementary analysis of economic burden. A predictive model was fitted to national surveillance data. RESULTS: Thirty ESBL-positive and 96 ESBL-negative BSI cases were included. The excess LOS attributable to ESBL-positive and ESBL-negative BSI was 9.4 (95% confidence interval [CI], 0.4-18.4) and 2.6 (95% CI, 0.7-5.9) days, respectively. ESBL positivity was therefore associated with 6.8 excess days and CHF 9,473 per BSI. The adjusted end-of-LOS HRs for ESBL-positive and ESBL-negative BSI were 0.62 (95% CI, 0.43-0.89) and 0.90 (95% CI, 0.74-1.10), respectively. After reimbursement, the average financial loss per acute care episode in ESBL-positive BSI, ESBL-negative BSI, and control cohorts was CHF 48,674, 48,131, and 13,532, respectively. Our predictive model estimated that the nationwide cost of third-generation cephalosporin resistance would increase from CHF 2,084,000 in 2010 to CHF 3,526,000 in 2015. CONCLUSIONS: This is the first hospital-wide analysis of excess LOS attributable to ESBL positivity determined using multistate modeling to avoid time-dependent bias. These results may inform health-economic evaluations of interventions targeting ESBL control.

Resistance to amikacin and gentamicin among Gram-negative bloodstream isolates in a university hospital between 1989 and 1994.

OBJECTIVE: To characterize antimicrobial resistance patterns to amikacin (AN) and gentamicin (GM) among Gram-negative bloodstream isolates and to determine the possible relationship between use of AN and GM and the occurrence of antibiotic resistance during a 6-year period. METHODS: Standard media and techniques of isolation and identification were used. Antimicrobial susceptibility testing was performed with the disk diffusion method and API rapid ATB E strips. Data on consumption of aminoglycosides were collected by the central hospital pharmacy and were expressed as daily defined doses. RESULTS: One thousand nine hundred and four bloodstream isolates were tested for AN and GM susceptibility between 1989 and 1994. Activities of AN and GM remained high during the study period against most isolates of Gram-negative bacteria. No relationship could be observed between the use of AN/GM and the rate of AN/GM resistance. Nosocomial Gram-negative bloodstream isolates showed a higher degree of resistance towards both AN (3.9% of all nosocomial isolates) and GM (7.9%) than community-acquired isolates (1.8% toward AN and 3.1% towards GM, respectively). There was a significant increase (P=0.004) in the risk of GM resistance in patients with nosocomial Gram-negative bacteremia detected more than 14 days after admission. The proportion of GM-susceptible Pseudomonas aeruginosa isolates decreased linearly from 97% for infections acquired between day 3 and day 10 following admission to 80% for bacteremia developing 30 days or more after admission (P=0.008). CONCLUSIONS: AN and GM remain highly active antimicrobial drugs for treatment of GNB in times of growing resistance to cephalosporins and fluoroquinolones.
