Inappropriate antibiotic use in a tertiary care center in Thailand: an incidence study and review of experience in Thailand.

The incidence and patterns of and factors associated with inappropriate antibiotic use were studied in a tertiary care center in Thailand. The incidence of inappropriate antibiotic use was 25%. Admission to the surgical department (adjusted odds ratio, 2.0; P=.02) and to the obstetrics and gynecology department (adjusted odds ratio, 2.0; P=.03) were associated with inappropriate antibiotic use, whereas consultation with an infectious diseases specialist was protective against inappropriate antibiotic use (adjusted odds ratio, 0.15; P=.01).     

Inappropriate use of antifungal medications in a tertiary care center in Thailand: a prospective study

The incidence and factors associated with inappropriate use of antifungal medications were studied in a Thai tertiary care center. The incidence of inappropriate antifungal use was 74% (in 42 of 57 patients). Isolation of Candida species from urine (P = .004) was a risk factor, whereas receipt of an infectious diseases consultation (P = .004) was protective.     

Outbreak of postoperative endophthalmitis in a Thai tertiary care center.

We performed a study with a 1:3 ratio of case patients (n = 11) to control patients (n = 33) to evaluate risk factors for postoperative endophthalmitis in a Thai tertiary care center. Multivariate analysis revealed that diabetes mellitus and surgeon A were associated risk factors. Preoperative diabetes mellitus control and the improvement of infection control practices led to the termination of the outbreak.     

Varicella zoster virus infection of the central nervous system in a tertiary care center in Lebanon

ObjectiveTo describe the clinical manifestations and treatment outcomes of patients with VZV meningitis and encephalitis consulting at two medical centers in Lebanon.MethodsRetrospective study of patients with VZV meningitis and/or encephalitis confirmed by positive cerebrospinal fluid (CSF) VZV PCR.ResultsTwenty patients were identified (13 males). The average age was 49.7 ± 22.2 years. The most common complaint was headache (n = 17/20). Common comorbidities included hypertension (n = 7/20) and diabetes mellitus (n = 5/20). Immunosuppression was reported in two patients. Vesicles were only observed in eight patients. Altered mental status, focal neurological deficits, and fever were documented in six, two, and four patients respectively. All patients had CSF leukocytosis with lymphocytic predominance, normal CSF/serum glucose ratio, and high CSF protein. Eighteen patients had brain CT scans showing no relevant findings. Two of 12 patients with brain MRI had focal abnormalities. Unilateral temporal slow waves were observed in three of four patients who underwent electroencephalograms. Four patients had encephalitis and 16 had meningitis. Eighteen patients received an antiviral therapy. Treatment either included intravenous acyclovir or oral valacyclovir. The encephalitis and meningitis groups had comparable mean duration of treatment (13.5 ± 6.6 vs. 12.2 ± 5.4, respectively). All admitted patients showed clinical cure with no reported neurological sequelae.ConclusionVZV infection should be suspected in any patient with signs and symptoms of viral meningitis or encephalitis, irrespective of age, immune status, presence or absence of vesicles, fever, or neck stiffness.     

Effectiveness of multifaceted hospitalwide quality improvement programs featuring an intervention to remove unnecessary urinary catheters at a tertiary care center in Thailand.

OBJECTIVE: To evaluate the efficacy of a multifaceted hospitalwide quality improvement program that featured an intervention to remind physicians to remove unnecessary urinary catheters. METHODS: A hospitalwide preintervention-postintervention study was conducted over 2 years (July 1, 2004, through June 30, 2006). The intervention consisted of nurse-generated daily reminders that were used by an intervention team to remind physicians to remove unnecessary urinary catheters, beginning 3 days after insertion. Clinical, microbiological, pharmaceutical, and cost data were collected. RESULTS: A total of 2,412 patients were enrolled in the study. No differences were found in the demographic and/or clinical characteristics of patients between the preintervention and postintervention periods. After the intervention, reductions were found in the rate of inappropriate urinary catheterization (mean rate, preintervention vs postintervention, 20.4% vs 11% [P=.04]), the rate of catheter-associated urinary tract infection (CA-UTI) (mean rate, 21.5 vs 5.2 infections per 1,000 catheter-days [P<.001]), the duration of urinary catheterization (mean, 11 vs 3 days [P<.001]), and the total length of hospitalization (mean, 16 vs 5 days [P<.001]). A linear relationship was seen between the monthly average duration of catheterization and the rate of CA-UTI (r=0.89; P<.001). The intervention had the greatest impact on the rate of CA-UTI in the intensive care units (mean rate, preintervention vs postintervention, 23.4 vs 3.5 infections per 1,000 catheter-days [P=.01]). The monthly hospital costs for antibiotics to treat CA-UTI were reduced by 63% (mean, $3,739 vs $1,378 [P<.001]), and the hospitalization cost for each patient during the intervention was reduced by 58% (mean, $366 vs $154 [P<.001]). CONCLUSIONS: This study suggests that a multifaceted intervention to remind physicians to remove unnecessary urinary catheters can significantly reduced the duration of urinary catheterization and the CA-UTI rate in a hospital in a developing country.     

Impact of an infection control program on the prevalence of nosocomial infections at a tertiary care center in Switzerland .

OBJECTIVE: To study the impact of a multimodal infection control program on the rate of nosocomial infections at a 550-bed tertiary care center. METHODS: Before and after the implementation of an infection control program, the rate of nosocomial infection was recorded in time-interval prevalence studies. Hand hygiene compliance was studied before and after the intervention. As a surrogate marker of compliance, the amount of alcohol-based hand rub consumed before the intervention was compared with the amount consumed after the intervention. The intervention included additional staff for infection control, repeated instructions for hand hygiene, new guidelines for preoperative antibiotic prophylaxis, and isolation of patients infected or colonized with multidrug-resistant bacteria. RESULTS: The rate of nosocomial infection decreased from approximately 11.7% to 6.8% in 2 years. The rate of hand hygiene compliance increased by 20.0%; it was 59.0% before the intervention and increased to 79.0% afterward. These results correlate with data on the consumption of alcohol-based hand rub, but not with data on the use of antibiotics. CONCLUSION: Within 2 years, a multimodal infection control program intervention such as this one may reduce the rate of nosocomial infection at a tertiary care center by more than one-third and improve both the quality of care and patient outcomes. It may also generate considerable savings. Therefore, such programs should be promoted not only by hospital epidemiologists but also by hospital administrators.

A study of pregnancy outcomes in a maternity center and a tertiary care hospital.

This study compares 796 pregnancy outcomes at a maternity center (BMC) with 804 hospital (TJUH) pregnancy outcomes. The samples of pregnant women from the participating institutions were matched on sociodemographic characteristics; analysis of outcomes was performed controlling for medical-obstetric risk. Differences between the institutions were found mainly among women with low intrapartum risk. For these women, neonatal morbidity and length of infant nursery stay were lower at BMC than at TJUH. The percentage of infants with one-minute Apgar scores less than 7 or requiring resuscitation at birth was greater at BMC, but the percentage of infants with five-minute Apgar scores less than 7 as well as neonatal mortality rates did not differ between the two institutions. The number of women with intrapartum or postpartum fever was too small to permit comparison. The study results suggest that care delivered at BMC is safe with regard to the evaluative criteria used.     

Sickness-related absence among employees at a tertiary care center in Lebanon

The authors studied the rate of sickness-related absence of employees at a tertiary care center. They examined sickness-related absence records of employees, including nurses, food service workers, housekeeping, and security personnel, in a university teaching hospital in Lebanon over a period of 1 year. These departments included 1,010 employees, of which 47% took sickness absences during the study period. In all, 49.02% of the nursing employees, 43.67% of the food service workers, 37.79% of the housekeeping employees, and 47.5% of the protection/security workers took sickness-related absences. Employees in younger age groups took the majority of sicknessrelated absences; in general, these constituted short-duration sickness-related absences (relative to those taken by emploees in older age groups; dietary personnel were the exception to this pattern). Principal causes of sickness-related absences were respiratory illness and musculoskeletal problems. The authors observed that distribution of sickness-related absences among the departments studied was similar to the actual distribution of employees. They considered reasons for sicknessrelated absences as pertinent to each category.     

Update on patient radiation doses at a large tertiary care medical center.

Radiation procedures in diagnostic radiology and nuclear medicine examinations, especially at referral centers, contribute a significant proportion to population dose; hence, there is a presumed detriment. Knowledge of the magnitude of dose from each type of exam is helpful in determining where to implement dose reduction efforts. Additionally, new records of dose data facilitate comparisons with past measurements. In this paper, updated patient exam dose data (frequency and effective dose equivalent) are provided for a large, comprehensive, tertiary care medical center that served more than 340,000 patients in 1997. Patient billing code data were used to study 31 different types of diagnostic exams encompassed in five major categories (angiography, fluoroscopy, radiography, nuclear medicine, and computerized tomography). Organ doses for each radiographic and nuclear medicine exam were estimated using published Monte Carlo conversion factors and appropriate exposure values. Estimates of organ doses were utilized to compute effective dose equivalent (EDE) per ICRP 26 and collective effective dose equivalent. Mean effective dose equivalent was also calculated for each exam category. Total collective effective dose equivalent had decreased from 1988 (2,030 person-Sv) to 1997 (1,817 person-Sv). The largest contributors to collective effective dose equivalent were angiography (768 person-Sv), computerized tomography (447 person-Sv), and nuclear medicine (355 person-Sv). Radiography (150 person-Sv) and fluoroscopy (97 person-Sv) contributed the least to collective effective dose equivalent. Mean effective dose equivalent contributions remained the same, with angiography accounting for the highest component, followed by nuclear medicine, computerized tomography, fluoroscopy, and radiography, respectively. Effective dose equivalent, collective effective dose equivalent, and mean effective dose equivalent values were calculated and tabulated in five major categories. These data provide updated information as to trends in exam and; collective dose from 31 common types of radiologic exams performed at a large medical center, which can be used as an up to date baseline for analyses of trends in U.S. radiation doses due to medical imaging procedures. Although minor changes were observed in comparing the mean effective dose equivalent data to those of a previous study, substantial differences were evident in the collective effective dose equivalent data. This was due primarily to variations in the number of patients examined and changes in technology and practice.

Nosocomial pneumonia in a Canadian tertiary care center: a prospective surveillance study

OBJECTIVE: To determine the contribution of etiologic agents, including Legionella pneumophila and respiratory viruses to nosocomial pneumonia at a tertiary care center. DESIGN: Prospective surveillance of nosocomial pneumonia with standardized laboratory investigations. SETTING: A 1,100-bed tertiary care center. PATIENTS: All adult inpatients. RESULTS: One hundred and thirty-five Nosocomial pneumonias (5.7/1,000 discharges) were identified. Four (3.0%) were L pneumophila serogroup 1 infections (0.17/1,000 discharges). Legionellosis occurred in non-high-risk patients, and three cases would not have been identified without active surveillance. Viral seroconversion was identified in seven (19%) of 36 cases with specimens available (0.59/1,000 discharges): five influenza B, one influenza A, and one respiratory syncytial virus. IgM serology was positive in one case each for Mycoplasma pneumoniae and Chlamydia species. No geographical clustering was observed for viral infections, and these would not have been identified without active surveillance. Mortality for all nosocomial pneumonia was 25%. Patient factors significantly associated with a poorer outcome included older age, underlying disease, low serum albumin, renal insufficiency, lower platelet count, endotracheal intubation, respiratory failure, bacteremia, and use of antacids. CONCLUSIONS: This prospective surveillance suggested that L pneumophila and viral agents were uncommon causes of nosocomial pneumonia at our institution during this surveillance period.
