[Evaluation of the appropriateness of hospital admissions with the Italian version of the AEP in a university hospital]. / Analisi dell'appropriatezza organizzativa dei ricoveri ospedalieri mediante PRUO in un ospedale del Molise.

It has been carried out a survey to evaluate the appropriateness of hospital stay in a university hospital. The aims of the study were: to determine the amount of inappropriate hospital admissions and inappropriate days of stay in relation to either wards and characteristics of admission; to analyse the reasons for inappropriate patient stay. A randomised sample stratified by ward of discharge of 224 medical records were analysed using the Italian version of the Appropriateness Evaluation Protocol. 37.9% of the hospital admissions and 18.9% of hospitalisation days were judged to be inappropriate. The main reasons for categorising an admission or a day of stay as inappropriate were a) delay in performing elective surgery procedures; b) that the patient's problem could be treated on an outpatient basis; c) delay in performing diagnostic examinations. The univariate statistical analysis showed an association between appropriateness of hospital stay and gender age, ward of discharge, length of hospital stay and DRG type (medical/surgical). The study highlights a lower level of inappropriateness compared to the results of other investigations. Hints were also identified for achieving an improved efficiency at hospital level.

[Hospital infection prevention in an intensive care unit]. / Prevenzione delle infezioni ospedaliere in una terapia intensiva.

Aim of the study was to evaluate the efficacy of the hospital infection preventive procedures adopted in the intensive care unit (ICU) of the "S. Camillo-Forlanini" hospital in Rome. First the following prevention protocols were analysed: invasive procedures (intubation, CVC and urinary catheter), surveillance cultures, infection management and antimicrobial prophylaxis. Comparison with international guidelines was carried out and protocols enforcement by the personnel was verified. Secondly a one year longitudinal surveillance study was performed in order to monitor the following site-specific infection rates: pneumonia (PNE), blood stream infections (BSI), urinary tract infections (UTI), surgical site infections (SSI). According to CDC definitions all patients developing infection 48 hours or more after ward admission were included. Furthermore risk factors (i.e. age, sex, SAPS II), invasive procedures (i.e. endotracheal intubation, vascular and urinary catheterisation), microbiological isolates and their antibiotic susceptibility were screened. Overall 302 patients (191 men and 111 women) were admitted; age 55.1 +/- 20.7 years (mean), SAPS II 42.4 +/- 16.2 (mean) and average ward stay 12.5 +/- 21.7 days. Crude mortality was 15.9%. Results showed a total of 37 infection episodes (20 PNE , 7 BSI, 8 UTI and 2 SSI) in 33 patients (10.9%). Infection and mortality rates were among the lowest registered in other italian ICU's. Standardized infection rates associated to invasive procedures were: Ventilator-associated PNE rate (7.8/1000), central venous catheter-associated BSI rate (2.2/1000), urinary catheter-associated UTI rate (2.1/1000). The first (PNE) was higher than the NNIS mean rate, whwreas BSI and urinary catheter associated rates were minor than the mean rates reported by NNIS. Gram-negatives were 61.7%, gram-positives 27.6% and Candida spp. 10.6%. The results confirm the ICU successful preventive strategy.

[Hospital infection surveillance in 5 Roman intensive care units]. / Sorveglianza multicentrica delle infezioni ospedaliere in cinque terapie intensive romane.

The A.A. carried out a survey on hospital acquired infection (HAI) in the intensive care units (ICU) of five roman hospitals. The study monitored the following site-specific infection rates: pneumonia (PNE), blood stream infections (BSI), urinary tract infections (UTI), surgical site infections (SSI). According to CDC definitions all patients developing infection 48 hours or more after ward admission were included. Furthermore risk factors (i.e. age, sex, SAPS II), invasive procedures (i.e. endotracheal intubation, vascular and urinary catheterisation), microbiological isolates and their antibiotic susceptibility were screened. The overall 503 patients characteristics (i.e., age, length of stay, case-mix...) showed the wards as general ICU's. Although the SAPS II score was similar, mortality (18.2%-42.9%) and general infection rates (15.4%-40.4%) among the five ICU's were considerably variable (p < 0.05), as HAI episodes distribution by type: PNE (37-88%), BSI (6-42%), UTI (6-24%), SSI (3-7%) (p < 0.05). Also device-associated infection rates such as Ventilator-associated PNE (11.6-24.6@1000), Vascular catheter-associated BSI (3.4-19.2@1000). Urinary catheter-associated UTI (2.6-14.0@1000) and invasive procedures management were different. Among the infected patients the most commonly isolated microorganisms were P. aeruginosa and Staphylococcus spp., which presented a considerable antibiotic resistance. The study showed: 1) sampling (i.e. blood cultures, tracheal aspirate and urine samples) and laboratory methodology indispensable for a correct HAI diagnosis were not standardized in the five ICU's; 2) hospital infection control policy was not carried out in all ICU's. The study showed a lack of standardization which limits the comparability of the general roman ICU's.

[Activities at the Rome Anti-Rabies Center in 2000: analysis and proposals]. / Attività del Centro Antirabbico di Roma nel 2000: analisi e proposte.

The Authors analyzed data from the 1,817 patients (mean age 35.3 +/- 20.6, median 32) treated at the Antirabies Centre of Rome in the year 2000; of these 8.9% were immigrants. Dogs (84.1%) and cats (9.8%) were responsible for most bites. Stray animals were 39.9%, with an owner 58.3% and those without data 1.8%. Over 1/3 of patients could not refer the cause of bite. Most patients (93.0%) went first to hospital, where tetanus prophylaxis was administered preferably by immunoglobulins (25.0%) instead of vaccine (6.6%). Antirabies vaccine (HDCV and/or DEV) was prescribed to 777 patients (42.8%) and administered to 642 (35.3%), but only 296 (16.3%) of them received at least 5 doses. Veterinary observation always confirmed the absence of rabies in central Italy. Immunoglobulins were prescribed only to 14 patients. The data shown in this study emphasize the opportunity to differentiate the Italian antirabies protocol according to the geographic area.
