RESUMEN

BACKGROUND: Delayed-onset cytomegalovirus (CMV) disease can occur among heart transplant recipients after stopping anti-CMV prophylaxis. We evaluated a large, retrospective cohort of heart transplant recipients in the United States through the use of billing data from 3 Healthcare Cost and Utilization Project (HCUP) State Inpatient Databases (SID) to determine the epidemiology of delayed-onset CMV disease coded during hospital readmission. METHODS: We identified 2280 adult heart transplant recipients from 2004 to 2010 through the use of the California, Florida, and New York SID. Demographics, comorbidities, heart failure etiology, CMV disease, and inpatient death were identified. CMV disease was classified as early-onset (≤100 days) or delayed-onset (>100 days after transplant). Possible tissue invasion by CMV was determined through the use of codes for CMV pneumonitis, hepatitis, and gastrointestinal endoscopy. Multivariate analysis was performed with the use of Cox proportional hazards models. RESULTS: Delayed-onset CMV disease occurred in 7.5% (170/2280) and early-onset CMV disease occurred in 2.0% (45/2280) of heart transplant recipients. Risk factors for delayed-onset CMV disease included residence in a non-metropolitan locale (aHR. 1.8; 95% confidence interval [CI], 1.0-3.3) and ischemic cardiomyopathy as heart failure etiology (aHR, 1.8; 95% CI, 1.3-2.5). Inpatient death >100 days after transplant was associated with delayed-onset CMV disease with possible tissue invasion (aHR, 2.0; 95% CI, 1.1-3.8), transplant failure or rejection (aHR, 4.0; 95% CI, 2.7-5.8), and renal failure (aHR, 1.5; 95% CI, 1.1-2.0). CONCLUSIONS: Delayed-onset CMV disease is more common than early-onset CMV disease among heart transplant recipients. These results suggest that delayed-onset tissue-invasive CMV disease may be associated with an increased risk of death.

RESUMEN

OBJECTIVES: Although vitamin D is recognized as an important factor in bone health, its role in osteoarticular infections is unclear. We hypothesized that low vitamin D (25-hydroxycholecalciferol) levels are associated with a lower likelihood of treatment success in osteoarticular infections. METHODS: This was a retrospective cohort study of patients with orthopedic infections who had a 25-hydroxycholecalciferol level drawn when their infection was diagnosed. Outcomes were determined at early (3-6 months) and late (≥ 6 months) follow-up after completing intravenous antibiotics. RESULTS: We included 223 patients seen during an 11-month period with osteoarticular infections and baseline 25-hydroxycholecalciferol levels. During the initial inpatient management of the infection, hypovitaminosis D was identified and treated. The mean 25-hydroxycholecalciferol level was 23 ± 14 ng/ml; 167 (75%) patients had levels <30 ng/ml. Overall, infection treatment success was 91% (159/174) at early follow-up and 88% (145/164) at late follow-up. 25-Hydroxycholecalciferol baseline levels were similar in those with and without successful clinical outcomes, both at early (25 ± 15 vs. 21 ± 9 ng/ml; p=0.3) and late follow-up (25 ± 15 vs. 23 ± 16 ng/ml; p=0.6). CONCLUSIONS: To our knowledge this is the first report on hypovitaminosis D and its impact on outcomes of osteoarticular infections. Hypovitaminosis D was frequent in this cohort. With vitamin D repletion, there was no difference in treatment success whether patients had baseline hypovitaminosis or not.

RESUMEN

The tuberculin skin test (TST) is an important tool for the detection of latent tuberculosis (TB) and the identification of health care workers (HCWs) who require chemoprophylaxis. Although TST is inexpensive, easily available and the preferred test in most TB-prevalent settings, it has recognised limitations, including subjective interpretation, false positivity, cross reactivity with non-tuberculous mycobacteria, administration errors and the requirement for two visits. Given these limitations and the unavailability of better screening tests in resource-limited settings, the acceptance rate for chemoprophylaxis among HCWs has remained low. Furthermore, chemoprophylaxis in these settings is complicated by the high rate of drug-resistant TB, potential adverse reactions, prescription of chemoprophylaxis in undiagnosed active TB patients and the unavailability of follow-up systems provided by occupational health programmes. In the present article, we provide our viewpoint and a practical approach along with existing evidence supporting or discouraging the use of TST and isoniazid chemoprophylaxis for TB screening and management among HCWs in TB-prevalent settings.

RESUMEN

OBJECTIVE: To assess the prognostic significance of persistent low-level viraemia (PLV, defined as persistent plasma viral loads of 51-1000 HIV-1 RNA copies/mL for at least 3 months) in patients who had achieved viral suppression on antiretroviral therapy (ART). METHODS: A retrospective cohort of HIV-infected patients who received ART, were followed-up for > or =12 months, made regular visits to the clinic during which blood tests were performed for an ultrasensitive HIV RNA assay every 3 months, and achieved viral loads <50 copies/mL were evaluated. Virological failure was defined as two consecutive viral load measurements >1000 copies/mL. RESULTS: Of 362 patients, 78 (27.5%) experienced PLV. The demographics of patients with and without PLV were similar. PLV occurred at a mean (+/-standard deviation) of 22.6+/-16.9 months after ART initiation and lasted for 6.4+/-3.4 months. During a median follow-up of 29.5 months, patients with PLV had a higher rate of virological failure (39.7% vs 9.2%; P < 0.001). The median time to failure was 68.4 months [95% confidence interval (CI) 37.0-99.7] for patients with PLV and >72 months for patients without PLV (log rank test, P < 0.001). By Cox regression, patients with PLV had a greater risk of virological failure [hazard ratio (HR) 3.8; 95% CI 2.2-6.4; P < 0.001]. Among patients with PLV, a PLV of >400 copies/mL (HR 3.3; 95% CI 1.5-7.1; P = 0.003) and a history of ART (HR 2.4; 95% CI 1.0-5.7; P = 0.042) predicted virological failure. CONCLUSIONS: PLV is associated with virological failure. Patients with a PLV >400 copies/mL and a history of ART experience are more likely to experience virological failure. Patients with PLV should be considered for treatment optimization and interventional studies.

RESUMEN

The growth of human immunodeficiency virus type-1 (HIV) infection among women in the USA has been coincident with an international momentum to better address the specific health care needs of women. This paper provides an overview of a demonstration model for comprehensive HIV care of adolescent and adult women in an academic setting. The paper contains a descriptive summary of a university-based demonstration model of comprehensive care for women with HIV infection. During 1997-1998, there were 279 urban and rural Midwest adolescent and adult women with HIV infection in care at this model programme. Medical care encompassed subspecialty HIV care, obstetrical and gynaecological care, primary care of non-HIV comorbidities, mental health assessments and family planning in a safe, university-based environment. For 279 women during the two-year period, health services included the detection and treatment of sexually transmitted diseases (56%) and cervical dysplasia (35%), perinatal care (12%) and screening and referral for substance abuse treatment (30%). There was no mother-to-child HIV transmission among 33 pregnant women enrolled in the Center prior to delivery, and transmission by three of nine women enrolled after delivery. Only 167 (60%) women were compliant with biannual medical visits during 1997-1998. Integral to the health services delivery was the provision of ancillary support services intended to enhance optimal medical care for this cohort of women. This university-based model of care also incorporated HIV provider training and formative HIV research. Structured medical and public health experiential learning opportunities occurred for medical and social work students, medicine residents, infectious diseases fellows, nurses and other professional health care workers. Clinical investigations of adolescent and adult women have complemented care and training, with funded research in HIV medication adherence and health services research. In follow-up, 71% of these women remained active in care in 1999. Retention of vulnerable populations in care may be a big challenge over the next decade, despite the availability of potent antiretroviral therapies.

RESUMEN

All patients admitted to the medical and surgical intensive care units of a 500-bed nonteaching suburban hospital were followed prospectively for the occurrence of nosocomial primary bloodstream infections for 21 months. The incidence of primary bloodstream infection was 38 (1%) of 3163 patients; among patients with central venous catheters, it was 34 (4%) of 920 patients, or 4.0 infections per 1000 catheter-days. Ventilator-associated pneumonia, congestive heart failure, and each intravascular catheter inserted were independently associated with the development of a nosocomial primary bloodstream infection. Among infected patients, the crude mortality rate was 53%, and these patients had longer stays in intensive care units and the hospital than did uninfected patients. Bloodstream infection, however, was not an independent risk factor for death. The incidence, risk factors, and serious outcomes of bloodstream infections in a nonteaching community hospital were similar to those seen in tertiary-care teaching hospitals.

RESUMEN

STUDY OBJECTIVES: To prospectively identify the occurrence of ventilator-associated pneumonia (VAP) in a community hospital, and to determine the risk factors for VAP and the influence of VAP on patient outcomes in a nonteaching institution. DESIGN: Prospective cohort study. SETTING: A medical ICU and a surgical ICU in a 500-bed private community nonteaching hospital: Missouri Baptist Hospital. PATIENTS: Between March 1998 and December 1999, all patients receiving mechanical ventilation who were admitted to the ICU setting were prospectively evaluated. INTERVENTION: Prospective patient surveillance and data collection. RESULTS: During a 22-month period, 3,171 patients were admitted to the medical and surgical ICUs. Eight hundred eighty patients (27.8%) received mechanical ventilation. VAP developed in 132 patients (15.0%) receiving mechanical ventilation. Three hundred one patients (34.2%) who received mechanical ventilation died during hospitalization. Logistic regression analysis demonstrated that tracheostomy (adjusted odds ratio [AOR], 6.71; 95% confidence interval [CI], 3.91 to 11.50; p < 0.001), multiple central venous line insertions (AOR, 4.20; 95% CI, 2.72 to 6.48; p < 0.001), reintubation (AOR, 2.88; 95% CI, 1.78 to 4.66; p < 0.001), and the use of antacids (AOR, 2.81; 95% CI, 1.19 to 6.64; p = 0.019) were independently associated with the development of VAP. The hospital mortality of patients with VAP was significantly greater than the mortality of patients without VAP (45.5% vs 32.2%, respectively; p = 0.004). The occurrence of bacteremia, compromised immune system, higher APACHE (acute physiology and chronic health evaluation) II scores, and older age were identified as independent predictors of hospital mortality. CONCLUSIONS: These data suggest that VAP is a common nosocomial infection in the community hospital setting. The risk factors for the development of VAP and risk factors for hospital mortality in a community hospital are similar to those identified from university-affiliated hospitals. These risk factors can potentially be employed to develop local strategies for the prevention of VAP. CLINICAL IMPLICATIONS: ICU clinicians should be aware of the risk factors associated with the development of VAP and the impact of VAP on clinical outcomes. More importantly, they should cooperate in the development of local multidisciplinary strategies aimed at the prevention of VAP and other nosocomial infections.

RESUMEN

OBJECTIVE: To evaluate a clinical guideline for the treatment of ventilator-associated pneumonia. DESIGN: Prospective before-and-after study design. SETTING: A medical intensive care unit from a university-affiliated, urban teaching hospital. PATIENTS: Between April 1999 and January 2000, 102 patients were prospectively evaluated. INTERVENTIONS: Prospective patient surveillance, data collection, and implementation of an antimicrobial guideline for the treatment of ventilator-associated pneumonia. MEASUREMENTS AND MAIN RESULTS: The main outcome evaluated was the initial administration of adequate antimicrobial treatment as determined by respiratory tract cultures. Secondary outcomes evaluated included the duration of antimicrobial treatment for ventilator-associated pneumonia, hospital mortality, intensive care unit and hospital lengths of stay, and the occurrence of a second episode of ventilator-associated pneumonia. Fifty consecutive patients with ventilator-associated pneumonia were evaluated in the before period and 52 consecutive patients with ventilator-associated pneumonia were evaluated in the after period. Severity of illness using Acute Physiology and Chronic Health Evaluation II (25.8 +/- 5.7 vs. 25.4 +/- 8.1, p =.798) and the clinical pulmonary infection scores (6.6 +/- 1.0 vs. 6.9 +/- 1.2, p =.105) were similar for patients during the two treatment periods. The initial administration of adequate antimicrobial treatment was statistically greater during the after period compared with the before period (94.2% vs. 48.0%, p <.001). The duration of antimicrobial treatment was statistically shorter during the after period compared with the before period (8.6 +/- 5.1 days vs. 14.8 +/- 8.1 days, p <.001). A second episode of ventilator-associated pneumonia occurred statistically less often among patients in the after period (7.7% vs. 24.0%, p =.030). CONCLUSIONS: The application of a clinical guideline for the treatment of ventilator-associated pneumonia can increase the initial administration of adequate antimicrobial treatment and decrease the overall duration of antibiotic treatment. These findings suggest that similar types of guidelines employing local microbiological data can be used to improve overall antibiotic utilization for the treatment of ventilator-associated pneumonia.

RESUMEN

Increasing antimicrobial resistance has resulted in a rapidly decreasing array of therapeutic options for infections in the critical care setting. Reports of reduced susceptibility to vancomycin in Staphylococcus aureus raise the possibility of patients being infected with a virulent pathogen for which most antibiotics are ineffective. Infection control methods to contain resistance, exclusive of antimicrobial restrictions, focus on surveillance to identify carriers of resistant organisms, prevention of nosocomial infections, adequate hand hygiene, isolation of patients who harbor resistant organisms, and the use of barrier techniques such as gowns and gloves. Surveillance using clinical isolates alone is inadequate for the identification of the majority of patients who carry resistant organisms. However, it is unclear what intensity of surveillance is needed to control the spread of these organisms in the intensive care unit in nonoutbreak situations. Attempts at eradicating carriage are often unsuccessful when there is extranasal colonization with methicillin-resistant S. aureus. Transmission of resistant organisms is primarily the result of transient contamination of healthcare workers' hands. Adequate handwashing, isolation of carriers, and barrier techniques are all necessary for containing resistance within the intensive care unit, however, compliance with these measures can be compromised by high staff turnover and heavy workload.

RESUMEN

The epidemiology of tuberculin reactivity among physicians practicing in regions of moderate tuberculosis prevalence is unknown. We prospectively assessed the epidemiology of tuberculin skin test (TST) reactivity among physicians in training in St. Louis between 1992 and 1998. Of 1574 physicians who were tested, 267 (17%) had positive TST results. Older age, birth outside of the United States, prior bacille Calmette-Guérin (BCG) vaccination, and practice in the fields of medicine, anesthesiology, or psychiatry were associated with a positive TST result. Among physicians born in the United States, 63 (5.7%) had positive TST results. Among physicians with > or = 2 documented TSTs, 12 had conversion to a positive TST (1.6%; 1.03 conversions per 100 person-years). Physicians in this study had a high rate of tuberculin reactivity, despite a low conversion rate. The relationship between TST conversion and birth outside of the United States and BCG vaccination suggests a booster phenomenon rather than true new TST conversions.

RESUMEN

Antimicrobial resistance has emerged as an important determinant of outcome for patients in the intensive care unit (ICU). This is largely due to the administration of inadequate antimicrobial treatment, which is most often related to bacterial antibiotic resistance. In addition, the escalating problem of antimicrobial resistance has substantially increased overall health care costs. This increase is a result of prolonged hospitalizations and convalescence associated with antibiotic treatment failures, the need to develop new antimicrobial agents, and the implementation of broader infection control and public health interventions aimed at curbing the spread of antibiotic-resistant pathogens. Intensive care units are unique because they house seriously ill patients in confined environments where antibiotic use is extremely common. They have been focal points for the emergence and spread of antibiotic-resistant pathogens. Effective strategies for the prevention of antimicrobial resistance in ICUs have focused on limiting the unnecessary use of antibiotics and increasing compliance with infection control practices. Clinicians caring for critically ill patients should consider antimicrobial resistance as part of their routine treatment plans. Careful, focused attention to this problem at the local ICU level, using a multidisciplinary approach, will have the greatest likelihood of limiting the development and dissemination of antibiotic-resistant infections.

RESUMEN

The authors surveyed 202 patients (54.5% male; 62.4% African American) enrolled at St. Louis HIV clinics to identify the importance of various sources of influence in their HIV medication decisions. Physicians were the most important source for 122 (60.4%) respondents, whereas prayer was most important for 24 respondents (11.9%). In multivariate tests controlling for CD4 counts, Caucasian men were more likely than Caucasian women and African Americans of both genders to select a physician as the most important source. African Americans were more likely than Caucasians to mention prayer as the most important source. Caucasians and those rating physicians as the most important source were more likely to be using antiretroviral medications. Respondents identified multiple important influences-hence the potential for conflicting messages about HIV medications. These findings have implications for health education practices and behavioral research in the medical setting.

RESUMEN

OBJECTIVE: The purpose of this study was to determine the impact of scheduled changes of antibiotic classes, used for the empirical treatment of suspected or documented Gram-negative bacterial infections, on the occurrence of inadequate antimicrobial treatment of nosocomial infections. DESIGN: Prospective observational study. SETTING: Medical (19-bed) and surgical (18-bed) intensive care units in an urban teaching hospital. PATIENTS: A total of 3,668 patients requiring intensive care unit admission were prospectively evaluated during three consecutive time periods. INTERVENTIONS: During each time period, one antibiotic class was selected for the empirical treatment of Gram-negative bacterial infections as follows: time period 1 (baseline period) (1,323 patients), ceftazidime; time period 2 (1,243 patients), ciprofloxacin; and time period 3 (1,102 patients), cefepime. MEASUREMENTS AND MAIN RESULTS: The overall administration of inadequate antimicrobial treatment for nosocomial infections decreased during the course of the study (6.1%, 4.7%, and 4.5%; p = .15). This was primarily because of a statistically significant decrease in the administration of inadequate antibiotic treatment for Gram-negative bacterial infections (4.4%, 2.1%, and 1.6%; p < .001). There were no statistically significant differences in the overall hospital mortality rate among the three time periods (15.6%, 16.4%, and 16.2%; p = .828) despite a significant increase in severity of illness as measured with Acute Physiology and Chronic Health Evaluation (APACHE) II scores (15.3 +/- 7.6, 15.7 +/- 8.0, and 20.7 +/- 8.6; p < .001). The hospital mortality rate decreased significantly during time period 3 (20.6%) compared with time period 1 (28.4%; p < .001) and time period 2 (29.5%; p < .001) for patients with an APACHE II score > or = 15. CONCLUSIONS: These data suggest that scheduled changes of antibiotic classes for the empirical treatment of Gram-negative bacterial infections can reduce the occurrence of inadequate antibiotic treatment for nosocomial infections. Reducing inadequate antibiotic administration may improve the outcomes of critically ill patients with APACHE II scores > or = 15.

RESUMEN

OBJECTIVE: The authors used data from a larger study to explore differences by gender, self-reported racial identification, and immune function in disclosure of HIV-positive serostatus to medical providers (dentists, family doctors, and emergency room [ER] and obstetrics-gynecology [ob/gyn] providers). METHOD: The authors analyzed interview responses from a convenience sample of African American and white men and women receiving HIV medical care at urban hospitals and clinics in St. Louis. Missouri. RESULTS: Of 179 respondents using at least one of three types of providers, 124 (69%) disclosed their HIV status to all applicable types of providers, 39 (22%) disclosed to only one or two types of providers, and 16 (9%) did not disclose to any of these types of providers. "Race" and CD4 count, but not gender, were independently associated with disclosure to dentists, family doctors, and ER providers in multivariate logistic regression analyses. CONCLUSIONS: Differences in disclosure rates, especially among patients who may be asymptomatic, suggest a need for public health education of both medical providers and patients with HIV.

RESUMEN

STUDY OBJECTIVES: To examine how deep chest surgical site infections following coronary artery bypass graft (CABG) surgery impact hospital inpatient length of stay (LOS), costs, and mortality. SETTING: A large, Midwestern community medical center. DESIGN: All CABG patients who developed deep chest infection (n = 41) were compared to a set of control subjects (n = 160) systematically selected as every tenth uninfected CABG patient. Clinical data were abstracted from patient records, and cost information was obtained from the cost accounting database of the hospital. RESULTS: Variables that significantly increased the risk of deep chest surgical site infection included obesity (odds ratio [OR], 11; p = 0. 0001), renal insufficiency (OR, 8.9; p = 0.0001), connective tissue disease (OR, 25.4; p = 0.0003), reexploration for bleeding (OR, 8.2; p = 0.0015), and the timing of antibiotic prophylaxis (> 60 min before incision; OR, 5.3; p = 0.0128). Within 1 year postoperatively, patients with deep chest surgical site infection had a mortality rate of 22%, vs 0.6% for uninfected patients (p = 0.0001). Infected patients also incurred an average of 20 additional hospital days (p = 0.0001). Univariate analysis indicated that patients who developed deep chest surgical site infection incurred $20,012 in additional costs in the first year (p = 0.0001). Infected patients who died incurred on average $60,547 more than infected patients who survived (p = 0.034). Multivariate analysis confirmed the magnitude of the estimate of the cost for deep chest surgical site infection ($18, 938; p = 0.0001). CONCLUSIONS: Deep chest surgical site infections following CABG surgery are associated with significant increases in LOS, hospitalization costs, and mortality. These results suggest the need for improved infection control measures to reduce deep chest surgical site infection rates.

RESUMEN

STUDY OBJECTIVE: To evaluate the relationship between the adequacy of antimicrobial treatment for bloodstream infections and clinical outcomes among patients requiring ICU admission. DESIGN: Prospective cohort study. SETTING: A medical ICU (19 beds) and a surgical ICU (18 beds) from a university-affiliated urban teaching hospital. PATIENTS: Between July 1997 and July 1999, 492 patients were prospectively evaluated. INTERVENTION: Prospective patient surveillance and data collection. RESULTS: One hundred forty-seven patients (29.9%) received inadequate antimicrobial treatment for their bloodstream infections. The hospital mortality rate of patients with a bloodstream infection receiving inadequate antimicrobial treatment (61.9%) was statistically greater than the hospital mortality rate of patients with a bloodstream infection who received adequate antimicrobial treatment (28.4%; relative risk, 2. 18; 95% confidence interval [CI], 1.77 to 2.69; p < 0.001). Multiple logistic regression analysis identified the administration of inadequate antimicrobial treatment as an independent determinant of hospital mortality (adjusted odds ratio [AOR], 6.86; 95% CI, 5.09 to 9.24; p < 0.001). The most commonly identified bloodstream pathogens and their associated rates of inadequate antimicrobial treatment included vancomycin-resistant enterococci (n = 17; 100%), Candida species (n = 41; 95.1%), oxacillin-resistant Staphylococcus aureus (n = 46; 32.6%), coagulase-negative staphylococci (n = 96; 21.9%), and Pseudomonas aeruginosa (n = 22; 10.0%). A statistically significant relationship was found between the rates of inadequate antimicrobial treatment for individual microorganisms and their associated rates of hospital mortality (Spearman correlation coefficient = 0.8287; p = 0.006). Multiple logistic regression analysis also demonstrated that a bloodstream infection attributed to Candida species (AOR, 51.86; 95% CI, 24.57 to 109.49; p < 0.001), prior administration of antibiotics during the same hospitalization (AOR, 2.08; 95% CI, 1.58 to 2.74; p = 0.008), decreasing serum albumin concentrations (1-g/dL decrements) (AOR, 1.37; 95% CI, 1.21 to 1.56; p = 0.014), and increasing central catheter duration (1-day increments) (AOR, 1.03; 95% CI, 1.02 to 1.04; p = 0.008) were independently associated with the administration of inadequate antimicrobial treatment. CONCLUSIONS: The administration of inadequate antimicrobial treatment to critically ill patients with bloodstream infections is associated with a greater hospital mortality compared with adequate antimicrobial treatment of bloodstream infections. These data suggest that clinical efforts should be aimed at reducing the administration of inadequate antimicrobial treatment to hospitalized patients with bloodstream infections, especially individuals infected with antibiotic-resistant bacteria and Candida species.

RESUMEN

In a recent survey of women with HIV, prayer was mentioned as a very important source in decision making about HIV antiretroviral therapy. As a follow-up to this finding, we conducted in-depth interviews with 51 women attending a comprehensive HIV care center to better understand the role of prayer in their decisions about taking antiretroviral therapy. The sample consisted predominately of African American (80%) women with a median age of 31 years from St. Louis and surrounding areas. Forty-seven (92%) reported that prayer was an important source for HIV medication decision making, with 30 (59%) considering prayer more important than the physician. Twenty-nine (57%) perceived a qualitative difference between prayer and the physician, which created a sense of conflict for some. Thirty (59%) wished that the physician knew more about the role of prayer in their lives. Our findings reveal compelling issues: (a) the willingness of the women to talk about prayer as a resource and its importance in HIV disease management, (b) the roles that prayer and the physician play in HIV medication decision-making, and (c) ways prayer can be addressed in a medical setting.

RESUMEN

We evaluated an amphotericin treatment strategy on the basis of duration of candidemia and clinical findings. Patients without neutropenia who had uncomplicated candidemia received 200 mg of amphotericin B over 5-7 days if they had had 1 day of positive cultures (PC group). The clinical cure rate was 93% (95% confidence interval [CI], 77%-99%; n=29 episodes) in the SC group, with no relapses (median follow-up, 272 days). The clinical cure rate was 83% (95% CI, 64%-94%; n=29 episodes) in the PC group, with 1 relapse (4.2%). The results of this pilot study suggest that patients with candidemia may be stratified into risk groups on the basis of the duration of positive blood cultures and other clinical findings. Decisions about the duration of therapy can be made 4-7 days after initiation of treatment. Carefully selected patients with transient uncomplicated candidemia may be safely treated with a short course of amphotericin B. Further prospective validation of this concept should be undertaken particularly to evaluate the impact on low-frequency late complications (e.g., endophthalmitis).

RESUMEN

BACKGROUND: Little is known about long-term improvements in medical students' knowledge, attitudes, and use of blood and body fluid precautions following preclinical training. METHODS: We evaluated an educational and skills-training program emphasizing double gloving for high-risk surgical procedures. Baseline surveys measuring knowledge, attitudes, and readiness to use specific precautions were completed by second-year (experimental) students before skills training and by third-year students (control) after their first clinical year. Follow-up surveys were completed 1 year later. Use of double gloves and protective eyewear during surgery clerkships was observed at baseline and follow-up. RESULTS: Of 149 students returning both surveys, the experimental group (n = 91) showed improvements in attitudes toward double gloving (P = 0.038) and use of double gloves during surgery at follow-up (relative risk = 1.95, 95% confidence interval = 1.06, 3.59). They expressed better attitudes toward (P = 0.003) and greater readiness to use (P = 0. 020) double gloves compared with controls at follow-up. They expressed better attitudes toward (P = 0.002) and greater readiness to use (P = 0.001) double gloves compared with controls when each had completed their first clinical year. CONCLUSION: The intervention was associated with improved attitudes toward and use of double gloves during surgery. The experimental group also expressed better attitudes and readiness to use double gloves compared with controls at follow-up.
