Efficacy of surveillance in nosocomial infection control in a surgical service.

OBJECTIVE: The purpose of this study was to assess the efficacy of surveillance of nosocomial infection in infection control at a service of general surgery. DESIGN: A surveillance study that included 1483 patients with a prospective identification of nosocomial infection was carried out. Its results were discussed with the staff, and a program on nosocomial infection control was implemented. One year after the pre-intervention study, a similar study that included 1506 patients was done. The main outcome measure was nosocomial infection. Incidence rates, incidence rate ratios, crude and multiple-risk factor adjusted for by Poisson regression analysis, and their 95% confidence interval rates were estimated. RESULTS: The characteristics of the patients enrolled in both studies were compared. After the intervention, the trend was to attend patients with more severe conditions: higher frequency of liver failure, chronic obstructive lung disease, higher proportion of dirty surgical wounds, and higher scores of both Study on the Efficacy of Nosocomial Infection Control (SENIC) and National Nosocomial Infections Surveillance indices. There were no significant differences in emergency surgery, duration of surgery, age, and sex. After the intervention, unnecessary chemoprophylaxis was drastically reduced, and a significant reduction in preoperative stay was observed. The nosocomial incidence rate fell from 18.4 to 14 per 1000 patient-days. This reduction yielded an incidence rate ratio of 0.56 (95% confidence interval, 0.43%-0.74%) adjusted for several variables (SENIC index, serum creatinine level, serum albumin level, antihistamine H2 level, surgical wound, body mass index, chemoprophylaxis, and community-acquired infection). Significant reductions in surgical site infection and urinary tract infection were observed, but the rate of respiratory tract infection remained unchanged. CONCLUSIONS: Surveillance was effective in reducing nosocomial infection.

Surgical site infection rates following cardiac surgery: the impact of a 6-year infection control program.

BACKGROUND: To evaluate the impact of an infection control program on surgical site infections (SSIs) complicating cardiac operations. METHODS: Prospective cohort study of patients undergoing cardiac operations. Interventions included prospective surveillance, povidone-iodine scrub showers, depilation before surgery, administration of preoperative antibiotic prophylaxis in the operating room, and postdischarge follow-up. Logistic regression models were fitted to assess infection rates over time, adjusting for factors known to affect SSI rates. RESULTS: The overall SSI rate for 2051 procedures was 10.4%. Rates of superficial and deep incisional SSIs remained unchanged over the study period. The rates of all organ/space infections, mediastinitis, and SSIs because of methicillin-resistant Staphylococcus aureus during the first 2 years were 3.25%, 2.22%, and 1.48%, respectively, and they decreased to 1.17%, 0.73%, and 0.73%, respectively, by the end of 2002 (P = .01, P = .01, and P = .09, respectively). The adjusted odds ratios for these 3 types of infection at the end of 2002 compared with December 31, 1998, were 0.19 (95% confidence interval [95% CI]: 0.07-0.48), 0.20 (95% CI: 0.06-0.66), and 0.28 (95% CI: 0.08-0.97), respectively. CONCLUSION: We observed significant reductions in organ/space infection rates, particularly mediastinitis. These differences remained significant when adjusted for potential confounding variables.

Bloodstream infection associated with needleless device use and the importance of infection-control practices in the home health care setting.

The influence of infection-control practices on bloodstream infection (BSI) risk was examined in a home health care setting in which three needleless devices were used consecutively. A case-control study and a retrospective cohort study were conducted. Risk factors for BSI included lower education level, younger age, having a central venous catheter (CVC) with multiple ports, or having a tunneled CVC. Among patients with a tunneled CVC, those at greatest risk had been allowed to shower rather than bathe and to get their exit site wet (P<.01). A high proportion (49%) of isolates were hydrophilic gram-negative bacteria, suggesting water sources of infection. In the cohort study, the BSI rate decreased as the frequency of changing the needleless device end cap increased from once weekly up to every 2 days, suggesting that the mechanism for BSI may involve contamination from the end cap. These findings may help to develop infection-control measures specific to home health care.

Roles of infection control nurses in provincial hospitals.

OBJECTIVE: To study the roles of infection control nurses (ICNs) in provincial hospitals. MATERIAL AND METHOD: Interview using a semi-structured interview form. RESULTS: Nine hospitals were enrolled by stratified sampling and 11 ICNs were included. Interview was done by the researcher during April and May 2002. All ICNs were female and in middle-aged group. Their mean experience in IC was 6.4 +/- 4.5 years. All ICNs could perform their duties according the roles set by the Department of Nursing in surveillance, personnel health, education, consultation, administration and quality improvement. Only about one half had experience in outbreak investigation and research. The commonest problems were excessive workload, lack of co-operation of medical personnel and lack of budget for immunization. CONCLUSION: All sampled ICNs in provincial hospitals performed their roles except only one half were involved in outbreak investigation and research.

Roles of infection control nurses in community hospitals.

OBJECTIVES: To evaluate the roles of infection control nurses (ICNs) and to detect problems, obstacles during work and needs for support in community hospitals. MATERIAL AND METHOD: A descriptive study, data from interview and questionnaire survey of 2 ICN from HA awarded hospitals and 146 IC nurses from hospitals applied for HA. RESULTS: From April to May 2002, questionnaires were returned for 115 (81.56%) plus 7 interviews for a total of 122 samples. The practiced HA IC roles included counseling (86.5%), surveillance (83.1%), administration (82.8%), employee health (82%), education (80%), quality development (76.3%), epidemic investigation (72.2%) and research (10.4%). The major problems and obstacles included inadequate IC knowledge, multiple responsibilities, inadequate cooperation, less administrative support, inadequate budget and documents. CONCLUSION: The present study suggested that the IC research role was the least done because of inadequate knowledge, too heavy work load and lack of administrative support.

Roles of infection control nurses in regional hospitals.

OBJECTIVES: To evaluate the roles of infection control nurses (ICNs) in regional hospitals and to detect problems, obstacles in practice and needs for support. MATERIAL AND METHOD: A descriptive study by interview and questionnaire survey of 16 ICNs from regional hospitals appling for HA. RESULTS: From February to April 2002, a study by interview and questionnaires was done in 16 ICNs from 10 regional hospitals applying for HA. Most of the ICNs practised IC roles according to HA criteria except for hospital employee health, NI surveillance and research. The major problems and obstacles included the lack of IC positions, inadequate ICNs, lack of support from hospital administrative personnel, too heavy work load, lack of: IC experts, budget for IC, equipment, IC research data and education material. CONCLUSION: The present study suggested that roles of ICNs in hospital employee health, NI surveillance and research were inadequate because of the lack of full time ICNs, too heavy a work load, lack of: IC consultants supply and administrative support.

The role of the infection control professional in the intensive care unit.

By design, multiple invasive procedures are performed in the intensive care unit (ICU). Although great care is taken to control morbidity and forestall mortality, this invasive environment places ICU patients and staff at immense risk of nosocomial (hospital-acquired) infection. The role of the infection control professional (ICP) within the ICU involves data collection, dissemination of data with feedback, expertise in the investigation of outbreaks, product evaluation proficiency, and fluid consultation aptitude. This article provides an inside view of how specialty infection control staff and ICU staff can optimize infection control to decrease the incidence of nosocomial infections. A description of what the ICP does not do in the ICU is also given, providing a clear guideline for how these two disciplines can best provide a safe intensive care experience.

Obstetric infection control in a developing country.

In Ghana, infection has been identified as a major cause of birth-related mortality. Results of a 2-month observation of infection control practices among Ghanaian obstetric nurses and midwives indicated that most personnel did not practice basic rules of asepsis. Problems included frequent breaks in technique, inadequate sterilization and disinfection, and repeated exposure to large amounts of blood and vaginal secretions. Supplies were limited and, even when available, not always used appropriately. The situation in developing countries is different from that in the United States. Therefore, an observational needs assessment is essential to plan relevant and practical measures for change.

Infection control for the otolaryngologist in the era of severe acute respiratory syndrome.

OBJECTIVES: Severe acute respiratory syndrome (SARS) has affected more than 8400 persons in 28 countries, with more than 800 deaths. The current SARS outbreak, especially in North American health care centers, has motivated a re-evaluation of infection control practices in the hospital and clinic environment. These considerations are particularly important to otolaryngology, in which examination and diagnostic procedures often bring the otolaryngologist in close--if not direct--contact with the patient's upper airway, mucosa, and secretions. The otolaryngologist is at increased risk of contracting a respiratory pathogen. METHOD: A joint effort by the Department of Otolaryngology at Queen's University and the Infection Control Services of the Hotel Dieu Hospital, Kingston, Ontario, was carried out to develop specific infection control guidelines for the otolaryngologists using strategies from the Centers for Disease Control and Prevention in the United States and the Laboratory Center for Disease Control, Health Canada. RESULTS: A set of specific recommendations was developed for the otolaryngologists to augment current infection control, including diligent use of personal protective equipment with every patient encounter. Moreover, this equipment should be removed according to specific protocol, to avoid contamination of self, others, and surroundings. Finally, a number of practice modifications are being adopted as prudent precautionary measures. CONCLUSION: It is essential to adhere to these recommendations in order to protect the health and safety of clinicians, colleagues, and patients.

Changing the infection control paradigm from off-line to real time: the experience at Millard Fillmore Health System.

In 1993, several departments at Millard Fillmore Health System joined efforts to initiate a new approach to infection control. The main emphasis of this program is to move infection control to a real-time mode to manage patient outcomes daily. The principal objective was to decrease the number of nosocomial infections by 10%, with a particular emphasis on surgical-site infections. Besides real-time surveillance, we are critically evaluating several aspects of the management of nosocomial infections. High-level computer support has been the frame-work upon which this program was built. We have microcomputers that are linked directly to microbiology, pharmacy, billing, and admissions, downloading data several times daily. An expert software system merges all of the data, and from this we can target patients for real-time interventions. The computer system allows all inpatients to be screened for either infection control or antibiotic management interventions on a daily basis, with minimal time being spent on data collection and maximal efforts devoted to interventions at the bedside. Additionally, the infection management program will assist in maintaining the extraordinarily low expenditures on antimicrobial agents. During 1993, the Millard Fillmore Health System spent $924,884 on antibiotics, an amount approximately 50% that of comparably sized hospitals.

Role of infection control measures in limiting morbidity associated with multi-resistant organisms in critically ill patients.

A retrospective comparative study was performed to determine the impact of infection control measures (ICMs) on colonization and infections due to methicillin-resistant Staphylococcus aureus (MRSA), Klebsiella pneumoniae (producing transferable extended-spectrum beta-lactamase, KPESBL), and multi-resistant Enterobacter aerogenes (MREA) in intensive care unit patients. Infection Control Measures included surveillance cultures, isolation procedures and mupirocin for MRSA nasal carriage. The numbers of patients infected and/or colonized by MRSA, KPESBL or MREA were compared during two consecutive one-year periods (Period 1 before ICMs, and Period 2 after ICMs). The antibiotic consumption during the two periods was analysed. In Period 1 and Period 2, respectively, the rate of patients infected or colonized by at least one of the three organisms was 15% and 6.8% (P=0.001); by MRSA 7.7% and 2.6% (P=0. 004); by KPESBL 1.7% and 0% (P=0.25); and by MREA 5.6% and 4.3% (P=0. 47). During Period 2, there was a clear-cut decrease in the percentage of patients infected by MRSA (P=0.018), a non-significant decrease in those infected by KPESBL (P=0.06), and no decrease in patients infected by MREA (P=0.22). When calculated per 1000 patient-days, for Period 1 and Period 2, respectively, the rate of patients infected or colonized by at least one of the three organisms was 11.9 and 8.8; for MRSA it was 4 and 2.2; for KPESBL it was 1 and 0; and for MREA it was 4 and 4. Antibiotic cost was pound98.7 in Period 1 and pound62.7 in Period 2. ICMs contributed to the control of infections and colonizations due to MRSA and KPESBL but not those due to MREA.

Immunization of health-care workers: recommendations of the Advisory Committee on Immunization Practices (ACIP) and the Hospital Infection Control Practices Advisory Committee (HICPAC).

This report summarizes recommendations of the Advisory Committee on Immunization Practices (ACIP) concerning the use of certain immunizing agents in health-care workers (HCWs) in the United States. It was prepared in consultation with the Hospital Infection Control Practices Advisory Committee (HICPAC) and is consistent with current HICPAC guidelines for infection control in health-care personnel. These recommendations can assist hospital administrators, infection control practitioners, employee health physicians, and HCWs in optimizing infection prevention and control programs. Background information for each vaccine-preventable disease and specific recommendations for use of each vaccine are presented. The diseases are grouped into three categories: a) those for which active immunization is strongly recommended because of special risks for HCWs; b) those for which immunoprophylaxis is or may be indicated in certain circumstances; and c) those for which protection of all adults is recommended. This report reflects current ACIP recommendations at the time of publication. ACIP statements on individual vaccines and disease updates in MMWR should be consulted for more details regarding the epidemiology of the diseases, immunization schedules, vaccine doses, and the safety and efficacy of the vaccines.

Post-SARS infection control in the hospital and clinic.

The recent severe acute respiratory syndrome (SARS) outbreak has almost mandated a re-evaluation of infection control practices in hospitals, clinics, schools and domestic environments, especially for patients with respiratory tract symptoms. Triage, early case detection followed by prompt isolation and quarantine are major preventive measures. Respiratory tract infections are the most common childhood illnesses and paediatric SARS poses special problems in diagnosis because of its non-specific presentation. The main lessons learnt from the outbreak were: (1) despite well established guidelines on infection control precautions, poor understanding of underlying principles and deficiencies in compliance are common among healthcare professionals, especially during emergencies; (2) even a slight lapse can be fatal; and (3) over-protection can be counterproductive. Hence it is important to: (1) be protected to protect others; (2) be vigilant and prepared for emerging infections; (3) be proficient and scrupulous in infection control measures; (4) be apposite and practical on personal protective equipments to ensure sustainability; and (5) be dutiful and prompt in informing of potential threats and work closely with others.

Prion diseases--an evidence-based protocol for infection control.

Prion diseases are fatal, infectious, neurodegenerative disorders with special implications for infection control in the OR. The causative agent is highly resistant to disinfection and sterilization processes and has been transmitted during health care interactions. It is important to use evidence gained through research and case reports to minimize risk of infection. This article describes an infection control protocol developed for identifying high-risk patients, providing perioperative care, decontaminating the OR, and protecting health care personnel. This protocol provides multidisciplinary team members with a guideline for preventing transmission of these fatal diseases.

Infection control in the bronchoscopy suite. A review.

Bronchoscopy can occasionally transmit disease. Infection control in the bronchoscopy suite is especially important because of the risk of transmitting HIV or tuberculosis. Many case reports, patient series, and small studies have been published, but little comprehensive guidance is available for clinicians who wish to learn more about the problem and prevent it. We review the literature and describe three ways in which bronchoscopy can cause disease: by transmitting infections between patients, by transferring microorganisms within a patient, and by triggering coughing that can cause airborne infection of patients or health-care workers. Recommendations for infection control are listed; they include installing powerful air filters, using disposable bronchoscope suction valves, manually cleaning all equipment before disinfection, controlling patient coughing, and in some cases, giving patients prophylactic antibiotics.

Infection control in fixed prosthodontics.

The breadth and depth of our knowledge of infection control continues to increase in dramatic proportions. The literature is already massive and there is nothing to suggest an abatement of this situation. In truth, we can expect the very opposite; an escalation in attention at every level of concern, from the effectiveness of the chemical agents as actually used in the dental environment, to our methods of delivery, as well as the effects on the materials, equipment, and even the personnel in the dental setting. This trend undoubtedly will continue as our understanding of disease processes and the mechanisms of disease transmission increases. This will, in part, directly impact the scope and direction of future study of infection control practices in dentistry.

National survey of methicillin-resistant Staphylococcus aureus in Belgian hospitals: detection methods, prevalence trends and infection control measures. The Groupement pour le Dépistage, l'Etude et la Prévention des Infections Hospitalières.

A questionnaire survey of Belgian acute care hospitals was conducted to determine the methods used for detection of methicillin-resistant Staphylococcus aureus (MRSA), to estimate the prevalence of this organism during the period 1989-1991 and to describe the infection control measures used locally for limiting its spread. Questionnaires were returned by 144 acute care hospitals, with a coverage of 41 to 72% of hospitals by province. Methods used for detection of MRSA included disk diffusion (91%), microdilution panels (8%) and oxacillin agar screen (9%). Only 34% of laboratories performed disk diffusion testing under optimal conditions for detection of heterogenous resistance. Among 36 hospitals reporting complete susceptibility data of Staphylococcus aureus isolates tested during the study period (n = 24,153), a mean MRSA prevalence of 14% was found (range: 0-70%). The median prevalence increased from 9.5% in 1989 to 13.7% in 1991 and showed a significant linear increase during this period in 30% of these hospitals (p < 0.01). Precautions used for controlling spread of MRSA included hand decontamination using either soap and water or antimicrobial preparations (68% of hospitals), room decontamination (62%), patient isolation (55%) and various barrier precautions (24-49%). Carrier screening was performed in 37% of hospitals, but antibiotic decolonization was attempted in only 24%. This survey identified areas for improvement in MRSA detection methods and underscored the need for multicentric surveillance of MRSA prevalence and a reappraisal of MRSA control strategies in Belgian hospitals.
