National laboratory inventory as part of global poliovirus containment--United States, June 2002.
(57/671)
Since the initiation of the global poliomyelitis initiative in 1988 through 2001, the number of countries where polio is endemic decreased from 125 to 10, and the number of reported polio cases decreased >99%, from an estimated 350,000 to <1,000. The Global Commission for the Certification of the Eradication of Poliomyelitis, convened by the World Health Organization, will declare the world polio-free when all regions have documented the absence of wild poliovirus transmission for at least 3 consecutive years and when laboratories with wild poliovirus materials have implemented appropriate containment conditions.

Tripling survival from sudden cardiac arrest via early defibrillation without traditional education in cardiopulmonary resuscitation.
(58/671)
BACKGROUND: Early defibrillation is the most important intervention affecting survival from sudden cardiac arrest (SCA). To improve public access to early defibrillation, we established Piacenza Progetto Vita (PPV), the first system of out-of-hospital early defibrillation by first-responder volunteers. METHODS AND RESULTS: The system serves a population of 173 114 residents in the Piacenza region of Italy. Equipment for the system comprises 39 semiautomatic external biphasic defibrillators (AEDs): 12 placed in high-risk locations, 12 in lay-staffed ambulances, and 15 in police cars; 1285 lay volunteers trained in use of the AED, without traditional education in cardiac pulmonary resuscitation, responded to all cases of suspected SCA, in coordination with the Emergency Medical System (EMS). During the first 22 months, 354 SCA occurred (72+/-12 years, 73% witnessed). The PPV volunteers treated 143 SCA cases (40.4%), with an EMS call-to-arrival time of 4.8+/-1.2 minutes (versus 6.2+/-2.3 minutes for EMS, P=0.05). Overall survival rate to hospital discharge was tripled from 3.3% (7 of 211) for EMS intervention to 10.5% (15 of 143) for PPV intervention (P=0.006). The survival rate for witnessed SCA was tripled by PPV: 15.5% versus 4.3% in the EMS-treated group (P=0.002). A "shockable" rhythm was present in 23.8% (34 of 143) of the PPV patients versus 15.6% (33 of 211) of the EMS patients (P=0.055). The survival rate from shockable dysrhythmias was higher for PPV versus EMS: 44.1% (15 of 34) versus 21.2% (7 of 33), P=0.046. The neurologically intact survival rate was higher in PPV-treated versus EMS-treated patients: 8.4% (12 of 143) versus 2.4% (5 of 211), P=0.009. CONCLUSIONS: Broad dissemination of AEDs for use by nonmedical volunteers enabled early defibrillation and tripled the survival rate for out-of-hospital SCA. (+info)
Can environmental purchasing reduce mercury in U.S. health care?
(59/671)
Environmental purchasing represents an innovative approach to mercury control for the health care sector in the United States. The U.S. health care sector creates significant environmental impacts, including the release of toxic substances such as mercury. Our goal in this study was to provide the health care industry with a method of identifying the environmental impacts associated with the products they use. The Health Care Environmental Purchasing Tool (HCEPT) was developed and tested at nine health care facilities in the Great Lakes region of the United States. As a result, more than 1 kg of mercury was removed from four facilities. The complexity of the supply chain inhibits a direct environmental information exchange between health-care decision makers and suppliers. However, a dialogue is starting within the health care supply chain to address environmental issues. The HCEPT has been shown to assist health care facilities with that dialogue by identifying products that have environmental consequences. This promising tool is now available for further experimentation and modification, to facilitate overall environmental improvement, and to provide a systematic method for environmental assessment of health care products.

Potential impact of public access defibrillators on survival after out of hospital cardiopulmonary arrest: retrospective cohort study.
(60/671)
OBJECTIVE: To estimate the potential impact of public access defibrillators on overall survival after out of hospital cardiac arrest. DESIGN: Retrospective cohort study using data from an electronic register. A statistical model was used to estimate the effect on survival of placing public access defibrillators at suitable or possibly suitable sites. SETTING: Scottish Ambulance Service. SUBJECTS: Records of all out of hospital cardiac arrests due to heart disease in Scotland in 1991-8. MAIN OUTCOME MEASURES: Observed and predicted survival to discharge from hospital. RESULTS: Of 15 189 arrests, 12 004 (79.0%) occurred in sites not suitable for the location of public access defibrillators, 453 (3.0%) in sites where they may be suitable, and 2732 (18.0%) in suitable sites. Defibrillation was given in 67.9% of arrests that occurred in possibly suitable sites for locating defibrillators and in 72.9% of arrests that occurred in suitable sites. Compared with an actual overall survival of 744 (5.0%), the predicted survival with public access defibrillators ranged from 942 (6.3%) to 959 (6.5%), depending on the assumptions made regarding defibrillator coverage. CONCLUSIONS: The predicted increase in survival from targeted provision of public access defibrillators is less than the increase achievable through expansion of first responder defibrillation to non-ambulance personnel, such as police or firefighters, or of bystander cardiopulmonary resuscitation. Additional resources for wide scale coverage of public access defibrillators are probably not justified by the marginal improvement in survival. (+info)

A capacity mapping approach to public health training resources.
(62/671)
The capacity mapping approach can be used to identify existing community resources. As part of this approach, inventories are used to provide information for a capacity map. The authors describe the development of two inventories and a capacity map for public health workforce development. For the first inventory, the authors contacted 754 institutions to determine available public health training resources; 191 institutions reported resources, including 126 directly providing distance learning technologies and courses or modules addressing important competency domains. Distance learning technologies included video conferencing facilities (61%) and satellite download facilities (50%). For the second inventory, the authors obtained information on 129 distance-accessible public health training modules. The workforce development capacity map produced from these two inventories revealed substantial resources available for use by individuals or agencies wishing to improve training in public health competencies.

Dealing with office emergencies. Stepwise approach for family physicians.
(63/671)
OBJECTIVE: To develop a simple stepwise approach to initial management of emergencies in family physicians' offices; to review how to prepare health care teams and equipment; and to illustrate a general approach to three of the most common office emergencies. QUALITY OF EVIDENCE: MEDLINE was searched from January 1980 to December 2001. Articles were selected based on their clinical relevance, quality of evidence, and date of publication. We reviewed American family medicine, pediatric, dental, and dermatologic articles, but found that the area has not been well studied from a Canadian family medicine perspective. Consensus statements by specialty professional groups were used to identify accepted emergency medical treatments. MAIN MESSAGE: Family medicine offices are frequently poorly equipped and inadequately prepared to deal with emergencies. Straightforward emergency response plans can be designed and tailored to an office's risk profile. A systematic team approach and effective use of skills, support staff, and equipment is important. The general approach can be modified for specific patients or conditions. CONCLUSION: Family physicians can plan ahead and use a team approach to develop a simple stepwise response to emergency situations in the office. (+info)
Medical devices; classification for medical washer and medical washer-disinfector. Final rule.
(64/671)
The Food and Drug Administration (FDA) is classifying the medical washer and medical washer-disinfector intended for general medical purposes to clean and dry surgical instruments, decontaminate or disinfect anesthesia equipment, hollowware, and other medical devices into class II (special controls). FDA is also identifying the guidance document entitled "Class II Special Controls Guidance Document: Medical Washers and Medical Washer-Disinfectors" (the guidance) as the special control that, in addition to general controls, the agency believes will reasonably ensure the safety and effectiveness of the device. This action is being taken under the Federal Food, Drug, and Cosmetic Act (the act), as amended by the Medical Device Amendments of 1976 (the 1976 amendments), the Safe Medical Devices Act of 1990 (the SMDA), and the Food and Drug Administration Modernization Act of 1997 (the FDAMA).
