    Investigation of febrile passengers detected by infrared thermal scanning at an international airport

    AUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 1 2010
    William J. H. McBride
    Abstract Objective: To determine the best approach for the evaluation of fever, detected by infrared thermal scanning, at an international airport. Methods: Arriving passengers with fever were divided into three groups: community evaluation by a GP, with or without cost compensation, or evaluation at the airport by a health practitioner. Uptake of offered evaluations was measured, diagnoses were recorded, and region-specific rates of fever measured. Observations were made on practical aspects of thermal screening. Results: Over a six-month period, 181,759 passengers were screened for fever at the Cairns international airport, Queensland, Australia. Fever was identified in 118 (0.06%) of the arriving passengers and 76 were enrolled in the study. Only 19 of these passengers (25%) voluntarily underwent further evaluation. No differences were observed in the three approaches. Conclusions: Public health surveillance of febrile passengers arriving at an international airport should not rely on voluntary passenger participation for the detection of imported contagious diseases.

    Diagnosis Clusters for Emergency Medicine

    ACADEMIC EMERGENCY MEDICINE, Issue 12 2003
    Debbie A. Travers RN
    Objectives: Aggregated emergency department (ED) data are useful for research, ED operations, and public health surveillance. Diagnosis data are widely available as The International Classification of Diseases, version, 9, Clinical Modification (ICD-9-CM) codes; however, there are over 24,000 ICD-9-CM code-descriptor pairs. Standardized groupings (clusters) of ICD-9-CM codes have been developed by other disciplines, including family medicine (FM), internal medicine (IM), inpatient care (Agency for Healthcare Research and Quality [AHRQ]), and vital statistics (NCHS). The purpose of this study was to evaluate the coverage of four existing ICD-9-CM cluster systems for emergency medicine. Methods: In this descriptive study, four cluster systems were used to group ICD-9-CM final diagnosis data from a southeastern university tertiary referral center. Included were diagnoses for all ED visits in July 2000 and January 2001. In the comparative analysis, the authors determined the coverage in the four cluster systems, defined as the proportion of final diagnosis codes that were placed into clusters and the frequencies of diagnosis codes in each cluster. Results: The final sample included 7,543 visits with 19,530 diagnoses. Coverage of the ICD-9-CM codes in the ED sample was: AHRQ, 99%; NCHS, 88%; FM, 71%; IM, 68%. Seventy-six percent of the AHRQ clusters were small, defined as grouping <1% of the diagnosis codes in the sample. Conclusions: The AHRQ system provided the best coverage of ED ICD-9-CM codes. However, most of the clusters were small and not significantly different from the raw data. [source]

    Unintentional methadone-related overdose death in New Mexico (USA) and implications for surveillance, 1998,2002

    ADDICTION, Issue 2 2005

    ABSTRACT Aims To determine death rates from methadone over time, to characterize methadone-related death and to discuss public health surveillance of methadone-related death. Design We analyzed medical examiner data for all unintentional drug overdose deaths in New Mexico, USA, between 1998 and 2002. Measurements Age-adjusted death rates for methadone-related death, logistic regression models for likelihood of methadone-related death among all unintentional drug overdose deaths and bivariate comparisons within methadone-related death. Findings Of 1120 drug overdose deaths during this period, there were 143 (12.8%) methadone-related deaths; the death rate decreased over the time period, averaging 1.6 per 100 000. Of 143 methadone-related deaths, 22.4% were due to methadone alone, 23.8% were due to methadone/prescription drugs (no illicit drugs), 50.3% were due to methadone/illicit drugs and 3.5% were due to methadone/alcohol. These groups were significantly different in demographics, health history and circumstances of death. Of 79 decedents (55.2%) with a known source of methadone, 68 obtained methadone through a physician prescription (31 for methadone maintenance treatment (MMT), 27 for managing pain and 10 had unknown reason for prescription). Conclusions Methadone-related death rates and the proportion of methadone-related death among all drug overdose deaths decreased in New Mexico from 1998 to 2002. It is important for surveillance of methadone-related death to assess multiple drug causes, not just underlying cause. Also, methadone for pain management must be examined alongside MMT and when possible, methadone co-intoxication should be described in the context of other drugs causing death. [source]

    Breastfeeding promotion for infants in neonatal units: a systematic review

    CHILD: CARE, HEALTH AND DEVELOPMENT, Issue 2 2010
    M. J. Renfrew
    Abstract Background Breastfeeding/breastmilk feeding of infants in neonatal units is vital to the preservation of short- and long-term health, but rates are very low in many neonatal units internationally. The aim of this review was to evaluate the effectiveness of clinical, public health and health promotion interventions that may promote or inhibit breastfeeding/breastmilk feeding for infants admitted to neonatal units. Methods Systematic review with narrative synthesis. Studies were identified from structured searches of 19 electronic databases from inception to February 2008; hand searching of bibliographies; Advisory Group members helped identify additional sources. Inclusion criteria: controlled studies of interventions intended to increase breastfeeding/feeding with breastmilk that reported breastmilk feeding outcomes and included infants admitted to neonatal units, their mothers, families and caregivers. Data were extracted and appraised for quality using standard processes. Study selection, data extraction and quality assessment were independently checked. Study heterogeneity prevented meta-analysis. Results Forty-eight studies were identified, mainly measuring short-term outcomes of single interventions in stable infants. We report here a sub-set of 21 studies addressing interventions tested in at least one good-quality or more than one moderate-quality study. Effective interventions identified included kangaroo skin-to-skin contact, simultaneous milk expression, peer support in hospital and community, multidisciplinary staff training, and Unicef Baby Friendly accreditation of the associated maternity hospital. Conclusions Breastfeeding/breastmilk feeding is promoted by close, continuing skin-to-skin contact between mother and infant, effective breastmilk expression, peer support in hospital and community, and staff training. Evidence gaps include health outcomes and costs of intervening with less clinically stable infants, and maternal health and well-being. Effects of public health and policy interventions and the organization of neonatal services remain unclear. Infant feeding in neonatal units should be included in public health surveillance and policy development; relevant definitions are proposed. [source]
