Of the cases of VRE bacteremia in the current study, 38% were due to documented catheter-related infections, and in the remaining 62% the catheter tip was not cultured, suggesting that the rate of catheter-related VRE bacteremias could have been higher. Beezhold et al demonstrated that VRE could colonize the inguinal and antecubital skin in 86% of patients with VRE bacteremia, suggesting that VRE may be an important cause of catheter-related bacteremia in hospitalized patients. In addition, Bassetti et al demonstrated a correlation between zones of inhibition and the in vivo efficacy of AICs. Since most of the VRE isolates in our unit prior to the introduction of the AICs were susceptible to either minocycline or rifampin, and since the AICs had zones of inhibition against most of the VRE isolates, it is possible that the AIC significantly decreased the risk of catheter-related VRE bacteremia in our ICUs, resulting in a significant decrease in this type of infection. AIC in the ICU

Several investigators have demonstrated that the use of the AIC in the ICU was associated with a significant decrease in the cost of medical care through the prevention of CR-BSIs. Pittet et al estimated the extra cost of a single episode of nosocomial BSI to be $40,890 (in 1994 dollars). This could be converted to $44,864 per nosocomial BSI in 1999. The introduction of AICs into our adult ICU resulted in the prevention of at least 33 episodes of nosocomial BSI. This resulted in a cost saving of $1,480,512 for FY 1999. The added cost related to the AIC is $46 per catheter, which would result in a total of $21,528 for the purchase of the 468 AICs used in FY 1999. The net savings for FY 1999 would have been $1,458,984. However, it should be noted that this cost saving estimation did not differentiate between primary BSIs and CR-BSIs.

In conclusion, the introduction of AICs to the adult MICU and SICU was associated with a significant decrease in nosocomial primary Gram-positive and Gram-negative bacteremia. This reduction of nosocomial bacteremia was associated with a significant decrease in catheter-related infections and cases of nosocomial multidrug-resistant VRE bacteremia, as well as a significant decrease in the length of hospital and ICU stay. This significant decrease in nosocomial BSIs resulted in a net savings of at least $1,450,000 during FY 1999.

Studies evaluating the impact of long-term acute care (LTAC) hospitals on patient outcome have focused on patients requiring mechanical ventilation. In this context, LTAC hospitals have been compared with other types of weaning units. Survival until discharge in these settings ranged between 48% and 93%, and long-term survival ranged from as low as 23% at 1 year to as high as 53% at 4 years. The variability in reported success may be explained by differences among hospital admission criteria, case mix, and referral patterns. The primary aim of our study was to determine if survival of a cohort of patients admitted to an LTAC hospital could be predicted by age, race, number of residual organ system failures (OSFs) at the time of admission to the LTAC hospital, or APACHE III score at the time of admission to the LTAC. Long-term Acute Care

A number of models exist that predict survival in the ICU setting. One such early model was developed using cumulative OSFs over 7 days. The most well-known prognostic systems are those of APACHE medical systems, APACHE II and APACHE III scores, which describe a method for assessing group death rates among ICU admissions using first-day risk assessment. While of limited value for individual management decisions, they are useful for risk stratification, research, quality assurance, and utilization review. APACHE III is a proprietary tool. Other scoring systems include the Sequential Organ Failure Assessment, Therapeutic Intervention Scoring System, Mortality Prediction Model, and the Simplified Acute Physiology Score II. Most prognostic scoring systems, similar to APACHE, use the worst values in the first 24 h after ICU admission and thus do not account for the impact of response to therapy on prognosis. Serial reprognostication using modified APACHE III formulas was hoped to yield a dynamic risk of death with more reliable estimates of individual risk. The probability of survival decreased when the acute physiology score (APS) component of the modified APACHE III score increased over the first several days; it also increased, to a lesser degree, when the APS failed to improve.

Caution must be used when applying a model to a population other than that in which it was developed. APACHE III, when applied to a group of ICUs in the United Kingdom, overestimated death and had poor calibration and uniformity of fit. No predictive or descriptive models, to the best of our knowledge, have been developed in patients surviving the acute phase of critical illness requiring LTAC. Our objective was to determine the extent to which survival in these patients is associated with age, race, residual OSFs, or APACHE III score on admission to LTAC.

The patient was in no apparent distress. Examination revealed the following: oropharynx, moist mucosa and no lesions; chest, bilateral loud high pitched wheezing diffusely, with prolonged expiratory phase; cardiac, S1 S2, diminished, no murmur, regular rate and rhythm, and tachycardia; abdomen, soft, nontender, normal bowel sounds, and no hepatospleno-megaly; and extremities, no clubbing, cyanosis, or edema. The neurologic examination was unremarkable.

Laboratory Findings

Laboratory findings are as follows: WBC count, 9.8 X 103/^L with 94% polymorphonuclear neutrophils and 2% band neutrophils; hematocrit, 45%; and platelet count, 276 X 103/^L. Calcium measurement, liver function test results, and electrolyte levels were normal. No infiltrates were evident on chest radiograph, and ECG revealed no acute changes.

Clinical Course

The patient was admitted to the hospital with a diagnosis of asthma exacerbation. She improved with IV steroids, bronchodilators, and antibiotics Pharmacy. Prednisone online was tapered to 60 mg/d. Ten days after admission, she developed neck swelling and hoarseness with pronounced subcutaneous emphysema. Her chest was clear on examination, and the rest of her physical examination was otherwise unremarkable. Her chest radiograph revealed subcutaneous emphysema, pneumomediastinum, and no pneumothorax. On the 11th hospital day, the patient complained of abdominal pain. Examination showed diffuse abdominal tenderness; however, the abdomen was soft with no signs of peritoneal irritation. The patient’s WBC count increased to 23 X 103/^L, with 4% band neutrophils. CT of the abdomen with iodinated contrast medium (Gastrografin; Schering Diagnostics; Berlin, Germany) was nonrevealing. No intraperitoneal air was identified.

A surgeon was consulted on the 12th hospital day; the abdominal pain was attributed to pneumatosis coli. The patient continued to complain of increasing abdominal pain, although her abdominal examination remained unimpressive. The next day, the WBC count increased to 27 X 103/^L, with 8% band neutrophils. On the 14th hospital day, a second abdominal CT with gastrografin was nonrevealing. A chest radiograph and CT image at the level of mediastinum are shown below.

Community-acquired infections (ie, urinary tract, bloodstream, pneumonia, and soft-tissue infections) were defined according to the patient’s hospital admission diagnosis and the treating physicians’ orders in the medical record documenting the need for antibiotic treatment of a specific community-acquired infection. Additionally, all community-acquired infections were required to be established within 48 h of hospital admission. Similar temporal cutoffs for separating community-acquired infections from hospital-acquired infections have been proposed by other inves-tigators. Patients residing at a nursing home, a skilled care facility, or a rehabilitation center who developed an infection requiring hospital admission were classified as having community-acquired infection. Nosocomial infections (ie, urinary tract, bloodstream, pneumonia, and skin or soft-tissue infections) were defined according to the criteria established by the Centers for Disease Control and Prevention. The identified source of infection was required to be documented in the patient’s medical record. Clinically suspected infections without microbiological confirmation by either special stains (eg, Gram stain or potassium hydroxide stain) or a positive culture were not classified as microbiologically confirmed infection.

The diagnostic criteria for ventilator-associated pneumonia were modified from the criteria established by the American College of Chest Physicians and Hq Canadian pharmacy. Ventilator-associated pneumonia was considered to be present when a new or progressive roent-genographic infiltrate developed in conjunction with one of the following: radiographic evidence of pulmonary abscess formation (ie, cavitation within preexisting pulmonary infiltrates); histologic evidence of pneumonia in lung tissue; a positive blood or pleural fluid culture; or two conditions from among fever, leukocytosis, and purulent tracheal aspirate. Blood and pleural fluid cultures could not be related to another source, and both had to have been obtained within 48 h before or after the clinical suspicion of ventilator-associated pneumonia. Microorganisms recovered from blood or pleural fluid cultures also had to be identical to the organisms recovered from cultures of respiratory secretions (ie, tracheal aspirates or BAL fluid).

Prospective cohort studies performed during 1996 to 1998 by the Multicenter Airway Research Collaboration. Using a standardized protocol, researchers provided 24-h coverage for a median duration of 2 weeks per year. Adults with acute asthma were interviewed in the ED and by telephone 2 weeks after hospital discharge.

In the United States, asthma does not affect all racial/ethnic groups equally. Population studies have repeatedly found higher asthma prevalence among blacks compared to whites. Black patients with asthma also experience greater morbidity and mortality. Hispanic patients, especially those of Puerto Rican descent, likewise bear a greater asthma burden than whites.

The reasons for racial/ethnic differences in asthma prevalence, morbidity, and mortality remain unclear.

While evidence for the genetic basis of asthma is clear, information about the contribution of genetic factors to race/ethnicity differences in asthma is lacking. Rather, other nongenetic factors have been implicated, such as lower socioeconomic status (SES) and its correlates, including greater allergen and irritant exposure and poor access to and compliance with state of the art management.

Most published studies on emergency department (ED) utilization by asthmatic adults of different racial/ethnic backgrounds have used retrospective reviews of archived or billing data. This restricts the range of variables that can be examined and leads to an incomplete picture of what actually happens to patients while they are in the ED Viagra in Canada. To further examine the role of race/ethnicity in asthma among adults presenting to the ED, we examined prospective data from the Multicenter Airway Research Collaboration (MARC). Based on previous research, we hypothesized that black and Hispanic asthma patients would be (1) in more severe respiratory distress on arrival to the ED, (2) more likely to receive substandard care while in the ED, (3) hospitalized more often during their index ED visit, and (4) more likely to relapse or have continued symptoms during the 2 weeks after hospital discharge. We further hypothesized that, after statistically controlling for factors thought to be confounders of the relation between race/ethnicity and illness severity (ie, education level, income, insurance status, and access to a primary care provider [PCP]), the observed racial/ethnic differences either would disappear or be dramatically reduced.
