Looking Back and Moving Forward: The Evolution and Potential Opportunities for the Future of Alcohol Outlet Density Measurement.

The literature consistently finds that areas with greater density of alcohol outlets (places that sell alcohol) tend to have higher levels of public health harms. However, conflicting findings arise when researchers drill down to identify the type(s) of alcohol outlets with the strongest associations with harms and the mechanisms that explain these associations. These disagreements could be a result of the outdated methods commonly used to quantify the alcohol environment: counts of the number of outlets in an area. This manuscript reviews the events and ideas that shaped the literature on the physical alcohol environment. It then defines the three main methods used to measure alcohol outlet density, conducts an exploratory factor analysis to explore the constructs underlying each method, and presents a novel conceptual framework that summarizes the three methods, their respective underlying constructs, and the setting(s) in which each may be most appropriate. The framework proposes that counts of alcohol outlets measure availability, proximity to the nearest outlet measures accessibility, and spatial access measures measure access, which comprises both availability and accessibility. We argue that researchers should consider using proximity and spatial access measures when possible and outline how doing so may present opportunities to advance theory and the design and implementation of alcohol outlet zoning regulations. Finally, this manuscript draws on research from other areas of the built environment to suggest opportunities to use novel methods to overcome common hurdles (e.g., separating subtypes of outlets, ecologic designs) and a new challenge on the horizon: home delivery.

Using the theory of normative social behavior to understand compliance with a smoke-free law in a middle-income country.

Smoke-free laws, which ban smoking in public venues, can be effective in protecting public health, but it has been difficult to achieve compliance with these laws in low- and middle-income countries. This study was conducted to understand the social norms around public smoking and learn how to improve compliance in Bogor, the first Indonesian city to pass a comprehensive smoke-free law. Eleven stratified focus groups were conducted (n = 89). Data were analyzed using the theory of normative social behavior, which posits that the influence of descriptive norms (perceptions about what other people do) on behavior is moderated by injunctive norms (perceptions about what one is expected to do), outcome expectations and group identity. The findings showed that participants perceived smoking in public to be common for men (descriptive norm). Public smoking is acceptable except in places with air conditioning and around children or pregnant women (injunctive norms). Men smoke without penalty of social or legal sanctions (outcome expectations) and may feel affiliation with other smokers (group identity). Together, these factors support public smoking and inhibit compliance with the smoke-free law. Theory-based communication and policy remedies are suggested that may bolster compliance with Bogor's smoke-free law given the current pro-smoking norms.

Detecting 2009 pandemic influenza A (H1N1) virus infection: availability of diagnostic testing led to rapid pandemic response.

Diagnostic tests for detecting emerging influenza virus strains with pandemic potential are critical for directing global influenza prevention and control activities. In 2008, the Centers for Disease Control and Prevention received US Food and Drug Administration approval for a highly sensitive influenza polymerase chain reaction (PCR) assay. Devices were deployed to public health laboratories in the United States and globally. Within 2 weeks of the first recognition of 2009 pandemic influenza H1N1, the Centers for Disease Control and Prevention developed and began distributing a new approved pandemic influenza H1N1 PCR assay, which used the previously deployed device platform to meet a >8-fold increase in specimen submissions. Rapid antigen tests were widely used by clinicians at the point of care; however, test sensitivity was low (40%-69%). Many clinical laboratories developed their own pandemic influenza H1N1 PCR assays to meet clinician demand. Future planning efforts should identify ways to improve availability of reliable testing to manage patient care and approaches for optimal use of molecular testing for detecting and controlling emerging influenza virus strains.

Methicillin-resistant Staphylococcus aureus infections among healthy full-term newborns.

OBJECTIVE: Methicillin-resistant Staphylococcus aureus (MRSA) strains have emerged in the community, causing disease among healthy people lacking traditional risk factors for MRSA infection. This article describes an outbreak of MRSA among healthy full-term newborns. DESIGN: Cases were identified and corresponding medical information collected. Telephone interviews were conducted with mothers of cases and surveillance cultures from mothers and newborns were performed. MRSA isolates were genotyped. SETTING: Hospital in Chicago, Illinois, USA. PARTICIPANTS: Newborns, their mothers and hospital healthcare workers. INTERVENTION: Nursery infection control practices were enhanced. The MRSA-colonised healthcare workers received intranasal mupirocin. MAIN OUTCOME: Within 4-23 days of birth, 11 newborns were identified with pustules, vesicles or blisters located on the head, groin, perineum, ears, legs, chin and trunk. All received antimicrobials and recovered without incident. RESULTS: None of 432 peripartum women, one of 399 newborns, and two of 135 healthcare workers were nasal MRSA carriers. Available isolates from six patients, two healthcare workers, and one from an MRSA-colonised newborn were similar by pulsed-field gel electrophoresis. Other than contact with the hospital, no common exposures of MRSA transmission were identified. CONCLUSIONS: MRSA strains that initially emerged in the community are now causing disease in healthcare settings. Providers should be aware that MRSA can cause skin infections among healthy newborns. Adherence to standard infection control practices is important to prevent transmission of MRSA in nurseries.

Community-associated methicillin-resistant Staphylococcus aureus skin infections in a religious community.

In September 2004, an outbreak of community-associated methicillin-resistant Staphylococcus aureus (MRSA) skin and soft tissue infections (SSTI) was reported among members of a religious community. We conducted a retrospective cohort study on all 175 community members; performed a nasal carriage survey, and environmental swab testing. We identified 24 MRSA cases (attack rate 14%). In multivariate analysis, sauna use [odds ratio (OR) 19.1, 95% confidence interval (CI) 2.7-206.1] and antimicrobial use within 12 months before infection (OR 11.7, 95% CI 2.9-47.6) were risk factors for infection. MRSA nasal carriage rate was 0.6% (1/174). Nine of 10 clinical isolates and an isolate from an administrative office within the community had the pulsed-field gel electrophoresis type USA300. Targeted hygiene improvement, wound care, and environmental cleaning were implemented. We describe the first reported outbreak of MRSA SSTI in a religious community. Adherence to appropriate personal and environmental hygiene might be critical factors in controlling transmission.

Rapid evaluation of risk of white particulate matter in blood components by a statewide survey of transfusion reactions.

BACKGROUND: In January 2003, white particulate matter (WPM) was detected in blood components. Because the composition and cause of WPM was not understood at that time, there was uncertainty about whether WPM could endanger patient safety. To investigate possible adverse patient events associated with WPM, transfusion reaction rates were examined. STUDY DESIGN AND METHODS: A questionnaire was distributed to Georgia medical centers. Data collected included the number of components transfused and reported adverse reactions by component type from January 2002 through January 2003, and date, reaction type, and blood supplier for events in January 2003. RESULTS: Of 124 transfusion services contacted, 108 (87%) responded. During the survey period, there were 1213 reported transfusion reactions and 528,412 units transfused, or 2.3 reactions per 1000 units transfused; for RBCs, 2.4 (range, 1.8-3.1); plasma, 1.5 (range, 0.6-3.5); and PLTs, 3.4 (2.1-5.4) per 1000 units. Transfusion reaction rates by component for January 2003 did not differ significantly from the rate for January 2002 or for the calendar year. The 86 reported reactions that occurred in January 2003 were attributed to bacterial contamination (n = 2, 2.3%), other febrile nonhemolytic (n = 49, 57.0%), allergic (n = 14, 16.3%), and "other" reactions (n = 21, 24.4%); the proportions of reaction types did not differ significantly during the month. CONCLUSION: No overall changes in reported adverse reaction rates occurred over the survey period or in the proportion of reaction types during January 2003 when WPM was detected. Statewide surveillance of transfusion reactions could be useful to evaluate potential threats to blood safety.

National shortages of antimicrobial agents: results of 2 surveys from the Infectious Diseases Society of America Emerging Infections Network.

In November 1999 and August 2000, the Infectious Diseases Society of America Emerging Infections Network (EIN) surveyed its members about shortages of antimicrobial agents in their hospitals and medical centers. Almost 90% of the members had encountered shortages of 1 or more agents in 1999. Of 496 respondents, 382 (77%) reported diminished supplies of penicillin G. Other agents in short supply included meropenem (38%), ticarcillin with or without clavulanate (24%), cefazolin (20%), gentamicin (50%), and nafcillin-oxacillin (13%). In 2000, 291 (60%) of 485 respondents reported shortages of penicillin G, but significantly fewer members had experienced a lack of other agents. In both surveys, members indicated that shortages had affected numerous therapeutic indications. In 1999, members estimated that shortages had affected thousands of patients. In 2000, they estimated that fewer patients were affected. The results of these 2 EIN surveys raise questions about the forces that govern the availability of these valuable therapeutic resources.

Steps towards constructing a global comparative risk analysis for alcohol consumption: determining indicators and empirical weights for patterns of drinking, deciding about theoretical minimum, and dealing with different consequences.

In order to conduct a comparative risk analysis for alcohol within the Global Burden of Disease Study (GBD 2000), several questions had to be answered. (1) What are the appropriate dimensions for alcohol consumption and how can they be categorized? The average volume of alcohol and patterns of drinking were selected as dimensions. Both dimensions could be looked upon as continuous but were categorized for practical purposes. The average volume of drinking was categorized into the following categories: abstention; drinking 1 (> 0-19.99 g pure alcohol daily for females, > 0-39.99 g for males); drinking 2 (20-39.99 g for females, 40-59.99 g for males), and drinking 3 (> or =40 g for females, > or =60 g for males). Patterns of drinking were categorized into four levels of detrimental impact based on an optimal scaling analysis of key informant ratings. (2) What is the theoretical minimum for both dimensions? A pattern of regular light drinking (at most 1 drink every day) was selected as theoretical minimum for established market economies for all people above age 45. For all other regions and age groups, the theoretical minimum was set to zero. Potential problems and uncertainties with this selection are discussed. (3) What are the health outcomes for alcohol and how do they relate to the dimensions? Overall, more than 60 disease conditions were identified as being related to alcohol consumption. Most chronic conditions seem to be related to volume only (exceptions are coronary heart disease and ischemic stroke), and most acute conditions seem to be related to volume and patterns. In addition, using methodology based on aggregate data, patterns were relevant for attributing harms for men but not women.

Treating cardiovascular disease with antimicrobial agents: a survey of knowledge, attitudes, and practices among physicians in the United States.

To assess physicians' knowledge, attitudes, and prescribing behaviors with regard to the association between Chlamydia pneumoniae and cardiovascular disease, we surveyed 750 physicians in Alaska, 1172 in West Virginia, and 569 infectious disease (ID) specialists in a nationwide network during February-May 1999. Eighty-five percent knew of the association between C. pneumoniae and atherosclerosis, but this awareness was more common among ID specialists and cardiologists than among generalists (96% vs. 77%; P<.001). Knowledge scores were significantly higher among ID specialists and cardiologists (P<.001) and among physicians who saw relatively more patients who had myocardial infarction and/or were at risk of atherosclerotic disease. Four percent of physicians had treated or recommended treating cardiovascular diseases with antimicrobial agents; this percentage was significantly higher among cardiologists, physicians who empirically treat patients with peptic ulcers with antimicrobial agents, and physicians with a relatively high knowledge score.

Sentinel surveillance as an alternative approach for monitoring antibiotic-resistant invasive pneumococcal disease in Washington State.

OBJECTIVES: As an alternative to statewide, mandated surveillance for antibiotic-resistant Streptococcus pneumoniae, a sentinel surveillance network of 27 hospitals was developed in Washington State. METHODS: The utility of targeted surveillance in population centers was assessed, current laboratory susceptibility testing practices were evaluated, and a baseline of pneumococcal resistance in Washington State was obtained for use in a statewide campaign promoting the judicious use of antibiotics. RESULTS: Between July 1997 and June 1998, 300 cases were reported; 67 (22%) had diminished susceptibility to penicillin. Only 191 (64%) were fully tested with penicillin and an extended-spectrum cephalosporin (ESC) as nationally recommended; 10.5% were resistant to penicillin and 6.8% were resistant to an ESC. The number of isolates inadequately tested declined through the year. The findings were similar to those from more comprehensive active surveillance in Oregon for the same time period. CONCLUSIONS: Targeted surveillance may be an adequate alternative for limited monitoring of antibiotic resistance for states that choose not to mandate reporting.

Electronic laboratory-based reporting for public health.

This article describes the role of laboratory-based reporting for public health in the United States and outlines a vision for electronic laboratory-based reporting (ELR). It emphasizes the importance of adoption and implementation of standards to the successful development of ELR. In particular, it describes the role of Health Level 7 as a standard for electronic message formats and the roles of LOINC (Logical Observation Identifiers, Names, and Codes) and SNOMED (Systematized Nomenclature for Human and Veterinary Medicine) as standards for test names and results, respectively. In addition, the article describes ongoing and planned ELR projects

Towards a global alcohol policy: alcohol, public health and the role of WHO.

In 1983 the World Health Assembly declared alcohol-related problems to be among the world's major health concerns. Since then, alcohol consumption has risen in developing countries, where it takes a heavy toll. Alcohol-related problems are at epidemic levels in the successor states of the Soviet Union and are responsible for 3.5% of disability-adjusted life years (DALYs) lost globally. Substantial evidence exists of the relationship between the levels and patterns of alcohol consumption on the one hand and the incidence of alcohol-related problems on the other. Over the past 20 years, research has demonstrated the effectiveness of public policies involving, for example, taxation and restrictions on alcohol availability, in reducing alcohol-related problems. In the wake of rapid economic globalization, many of these policies at national and subnational levels have been eroded, often with the support of international financial and development organizations. Development agencies and international trade agreements have treated alcohol as a normal commodity, overlooking the adverse consequences of its consumption on productivity and health. WHO is in a strong position to take the lead in developing a global alcohol policy aimed at reducing alcohol-related problems, providing scientific and statistical support, capacity-building, disseminating effective strategies and collaborating with other international organizations. Such leadership can play a significant part in diminishing the health and social problems associated with alcohol use.

A novel multiresistant Streptococcus pneumoniae serogroup 19 clone from Washington State identified by pulsed-field gel electrophoresis and restriction fragment length patterns.

In 1997, a cluster of multiresistant invasive serogroup 19 pneumococcus infections, including two fatalities, was reported in Washington State. Further investigation identified other cases. Fourteen Washington Streptococcus pneumoniae isolates, four from Alaska, and eight isolates from eastern Canada with reduced penicillin susceptibility (MIC of > or =1 microg/ml) were included in the study. Pulsed-field gel electrophoresis (PFGE) with ApaI, SacII, and SmaI restriction enzymes and IS1167 and mef restriction fragment length polymorphism (RFLP) pattern analysis were performed. Twenty of the 26 isolates had identical or related PFGE patterns, with two or all three enzymes, and identical or related IS1167 RFLP patterns, indicating that they were genetically related. These 20 isolates contained the mef gene conferring erythromycin resistance and had identical mef RFLP patterns. The PFGE and RFLP patterns were distinct from those of six multiresistant clones previously described and suggest that a new multiresistant clone has appeared in Washington, Alaska, and eastern Canada. This newly characterized clone should be included in the Pneumococcal Molecular Epidemiology Network.

Applying commodity chain analysis to changing modes of alcohol supply in a developing country.

Development sociology has used global commodity chains as one way of analyzing the dynamics of power and profit-taking in globalized production networks made up of multiple firms and occurring in multiple national settings. A substantial portion of the alcohol supply in developing countries is now produced through such production networks. Particularly in the beer and spirits trade, a small number of transnational firms control networks of local producers, importers, advertisers and distributors. These networks serve to embed transnational or transnationally backed brands in the local culture, using the tools of market research, product design and marketing to influence local drinking practices. Case materials from Malaysia's beer industry help to illustrate how the transnational firms dominate in those links of the commodity chain in which monopoly or oligopoly control is most likely to be found: the design/recipe and marketing/advertising nodes. Their control of the commodity chains and extraction of monopoly or oligopoly profits from them places substantial resources and influence over drinking settings and practices in foreign hands. The impact of this influence on state efficacy and autonomy in setting alcohol policy is an important subject for future research on the creation and implementation of effective alcohol policies in developing societies.

The ambiguous role of alcohol in economic and social development.

An increased and industrialized alcohol supply in a developing society is usually assumed to have positive effects on economic development, although it may be recognized that the effects on public health and order will be negative. There has been little attention to the potential for negative effects on the economic side. This paper directs attention to such factors as unemployment for cottage producers (often female heads of household) and reduced industrial employment as highly-automated "turnkey" brewers are installed. On the other hand, changes in the mode of production of alcoholic beverages may have little impact on the much larger work-force involved in serving or selling alcohol in retail trade. The net contribution of an increased and industrialized alcohol supply in terms of economic development is unclear, but industrialization and development bring with them increased demands for attention and sobriety, e.g. in motorized traffic and on the production line, which increased drinking may undercut. Decisions by international development agencies on investment in alcohol production and distribution should take account of both the positive and negative impacts on economic development as well as on public health. In line with this, the World Bank has recently decided to invest in alcohol industry projects only when there is a strong positive development impact and the project is "consistent with public health issues and social policy concerns".

Statewide system of electronic notifiable disease reporting from clinical laboratories: comparing automated reporting with conventional methods.

CONTEXT: Notifiable disease surveillance is essential to rapidly identify and respond to outbreaks so that further illness can be prevented. Automating reports from clinical laboratories has been proposed to reduce underreporting and delays. OBJECTIVE: To compare the timeliness and completeness of a prototypal electronic reporting system with that of conventional laboratory reporting. DESIGN: Laboratory-based reports for 5 conditions received at a state health department between July 1 and December 31, 1998, were reviewed. Completeness of coverage for each reporting system was estimated using capture-recapture methods. SETTING: Three statewide private clinical laboratories in Hawaii. MAIN OUTCOME MEASURES: The number and date of reports received, by reporting system, laboratory, and pathogen; completeness of data fields. RESULTS: A total of 357 unique reports of illness were identified; 201 (56%) were received solely through the automated electronic system, 32 (9%) through the conventional system only, and 124 (35%) through both. Thus, electronic reporting resulted in a 2.3-fold (95% confidence interval [CI], 2.0-2.6) increase in reports. Electronic reports arrived an average of 3.8 (95% CI, 2.6-5.0) days earlier than conventional reports. Of 21 data fields common to paper and electronic formats, electronic reports were significantly more likely to be complete for 12 and for 1 field with the conventional system. The estimated completeness of coverage for electronic reporting was 80% (95% CI, 75%-85%) [corrected] compared with 38% (95% CI, 36%-41%) [corrected] for the conventional system. CONCLUSIONS: In this evaluation, electronic reporting more than doubled the total number of laboratory-based reports received. On average, the electronic reports were more timely and more complete, suggesting that electronic reporting may ultimately facilitate more rapid and comprehensive institution of disease control measures.

Acute otitis media: management and surveillance in an era of pneumococcal resistance--a report from the Drug-resistant Streptococcus pneumoniae Therapeutic Working Group.

OBJECTIVE: To provide recommendations [corrected] for the management of acute otitis media (AOM) and the surveillance of drug-resistant Streptococcus pneumoniae (DRSP). Five questions were addressed: (1) Can amoxicillin remain the best initial antimicrobial agent for treating AOM in the current period of increasing prevalence of DRSP? (2) What are suitable alternative agents for use if amoxicillin fails? (3) Should empiric treatment of AOM vary by geographic region? (4) Where can clinicians learn about resistance patterns in their patient populations? (5) What modifications to laboratory surveillance would improve the utility of the information for clinicians treating AOM? PARTICIPANTS: Experts in the management of otitis media and the DRSP Therapeutic Working Group. This group was convened by the CDC to respond to changes in antimicrobial susceptibility among pneumococci and includes clinicians, academicians and public health practitioners. EVIDENCE: Published and unpublished data summarized from the scientific literature and experience from the experts present. PROCESS: [corrected] After group presentations and review of background materials, subgroup chairs prepared draft responses to the five questions, discussed the responses as a group and edited those responses [corrected]. CONCLUSIONS: Oral amoxicillin should remain the first line antimicrobial agent for treating AOM. In view of the increasing prevalence of DRSP, the safety of amoxicillin at higher than standard dosages and evidence that higher dosages of amoxicillin can achieve effective middle ear fluid concentrations, an increase in the dosage used for empiric treatment from 40 to 45 mg/kg/day to 80 to 90 mg/kg/day is recommended. For patients with clinically defined treatment failure after 3 days of therapy, useful alternative agents include oral amoxicillin-clavulanate, cefuroxime axetil and intramuscular ceftriaxone. Many of the 13 other Food and Drug Administration-approved otitis media drugs lack good evidence for efficacy against DRSP. Currently local surveillance data for pneumococcal resistance that are relevant for the clinical management of AOM are not available from most areas in the United States. Recommendations to improve surveillance include establishing criteria for setting susceptibility breakpoints for clinically appropriate antimicrobials to ensure relevance for treating AOM, testing middle ear fluid or nasal swab isolates in addition to sterile site isolates and testing of drugs that are useful in treating AOM. The management of otitis media has entered a new era with the development of DRSP. These recommendations are intended to provide a framework for appropriate clinical and public health responses to this problem.
