Point-of-Care Testing Practices, Failure Modes, and Risk-Mitigation Strategies in Emergency Medical Services Programs in the Canadian Province of Alberta.

CONTEXT.­: Emergency medical services (EMS) programs have been using point-of-care testing (POCT) for more than 20 years. However, only a handful of reports have been published in all of that time on POCT practices in field settings. OBJECTIVE.­: To provide an overview of POCT practices and failure modes in 3 of Alberta's EMS programs, and to propose risk-mitigation strategies for reducing or eliminating these failure modes. DESIGN.­: Details about POCT practices, failure modes, and risk-mitigation strategies were gathered through (1) conversations with personnel, (2) in-person tours of EMS bases, (3) accompaniment of EMS personnel on missions, (4) internet searches for publicly available information, and (5) a review of laboratory documents. RESULTS.­: Practices were most standardized and robust in the community paramedicine program (single service provider, full laboratory oversight), and least standardized and robust in the air ambulance program (4 service providers, limited laboratory oversight). Common failure modes across all 3 programs included device inoperability due to cold weather, analytical validation procedures that failed to consider the unique challenges of EMS settings, and a lack of real-time electronic transmission of results into the health care record. CONCLUSIONS.­: A provincial framework for POCT in EMS programs is desirable. Such a framework should include appropriate funding models, laboratory oversight of POCT, and relevant expertise on POCT in EMS settings. The framework should also incorporate specific guidance on quality standards that are needed to address the unique challenges of performing POCT in field settings.

Understanding variation in health service coverage and maternal health outcomes among districts in Rwanda - A qualitative study of local health workers' perceptions.

OBJECTIVE: To obtain the perspectives of health professionals and community health workers on factors that determine health service coverage and maternal health outcomes so as to understand variations between districts. METHODS: 16 Focus group discussions involving four different groups of participants were conducted in May 2015 in four purposively selected districts, complemented by three key informant interviews in one of the districts. RESULTS: The solidarity support for poor people and the interconnectedness between local leaders and heads of health facilities were identified as enablers of health service utilization. Geographical factors, in particular location close to borders with mobile populations and migrants, and large populations with sparsely distributed health infrastructure, exacerbated by hilly topography and muddy roads were identified as barriers. Shortages of skilled health providers at the level of district hospitals were cited as contributing to poor maternal health outcomes. CONCLUSION: There is a need to take into account disparities between districts when allocating staff and financial resources in order to achieve universal coverage for high-quality maternal health services and better outcomes. Local innovations such as the use of SMS and WhatsApp text messages by health workers and financial protection schemes for poor patients improve solidarity and are worth to be scaled up.

The division of labour between community medicine distributors influences the reach of mass drug administration: A cross-sectional study in rural Uganda.

BACKGROUND: Despite decades of community-based mass drug administration (MDA) for neglected tropical diseases, it remains an open question as to what constitutes the best combination of community medicine distributors (CMDs) for achieving high (>65%/75%) treatment rates within a village. METHODS: Routine community-based MDA was evaluated in Mayuge District, Uganda. For one month, we tracked 6,148 individuals aged 1+ years in 1,118 households from 28 villages. Praziquantel, albendazole, and ivermectin were distributed to treat Schistosoma mansoni, lymphatic filariasis, and soil-transmitted helminths. The similarity/diversity between CMDs was observed and used to predict the division of labour and overall village treatment rates. The division of labour was calculated by dividing the lowest treatment rate by the highest treatment rate achieved by two CMDs within a village. CMD similarity was measured for 16 characteristics including friendship network overlap, demographic and socioeconomic factors, methods of CMD selection, and years as CMD. Relevant variables for MDA outcomes were selected through least absolute shrinkage and selection operators with leave-one-out cross validation. Final models were run with ordinary least squares regression and robust standard errors. RESULTS: The percentage of individuals treated with at least one drug varied across villages from 2.79-89.74%. The only significant predictor (p-value<0.05) of village treatment rates was the division of labour. The estimated difference between a perfectly equal (a 50-50 split of individuals treated) and unequal (one CMD treating no one) division of labour was 39.69%. A direct tie (close friendship) between CMDs was associated with a nearly twofold more equitable distribution of labour when compared to CMDs without a direct tie. CONCLUSIONS: An equitable distribution of labour between CMDs may be essential for achieving treatment targets of 65%/75% within community-based MDA. To improve the effectiveness of CMDs, national programmes should explore interventions that seek to facilitate communication, friendship, and equal partnership between CMDs.

Profiling the best-performing community medicine distributors for mass drug administration: a comprehensive, data-driven analysis of treatment for schistosomiasis, lymphatic filariasis, and soil-transmitted helminths in Uganda.

BACKGROUND: The most prevalent neglected tropical diseases are treated through blanket drug distribution that is reliant on lay community medicine distributors (CMDs). Yet, treatment rates achieved by CMDs vary widely and it is not known which CMDs treat the most people. METHODS: In Mayuge District, Uganda, we tracked 6779 individuals (aged 1+ years) in 1238 households across 31 villages. Routine, community-based mass drug administration (MDA) was implemented for schistosomiasis, lymphatic filariasis, and soil-transmitted helminths. For each CMD, the percentage of eligible individuals treated (offered and ingested medicines) with at least one drug of praziquantel, albendazole, or ivermectin was examined. CMD attributes (more than 25) were measured, ranging from altruistic tendencies to socioeconomic characteristics to MDA-specific variables. The predictors of treatment rates achieved by CMDs were selected with least absolute shrinkage and selection operators and then analyzed in ordinary least squares regression with standard errors clustered by village. The influences of participant compliance and the ordering of drugs offered also were examined for the treatment rates achieved by CMDs. RESULTS: Overall, only 44.89% (3043/6779) of eligible individuals were treated with at least one drug. Treatment rates varied amongst CMDs from 0% to 84.25%. Treatment rate increases were associated (p value< 0.05) with CMDs who displayed altruistic biases towards their friends (13.88%), had friends who helped with MDA (8.43%), were male (11.96%), worked as fishermen/fishmongers (14.93%), and used protected drinking water sources (13.43%). Only 0.24% (16/6779) of all eligible individuals were noncompliant by refusing to ingest all offered drugs. Distributing praziquantel first was strongly, positively correlated (p value < 0.0001) with treatment rates for albendazole and ivermectin. CONCLUSIONS: These findings profile CMDs who treat the most people during routine MDA. Criteria currently used to select CMDs-community-wide meetings, educational attainment, age, years as a CMD, etc.-were uninformative. Participant noncompliance and the provision of praziquantel before albendazole and ivermectin did not negatively impact treatment rates achieved by CMDs. Engaging CMD friend groups with MDA, selecting CMDs who practise good preventative health behaviours, and including CMDs with high-risk occupations for endemic infections may improve MDA treatment rates. Evidence-based guidelines are needed to improve the monitoring, selection, and replacement of CMDs during MDA.

Community-based mass treatment with azithromycin for the elimination of yaws in Ghana-Results of a pilot study.

INTRODUCTION: The WHO yaws eradication strategy consists of one round of total community treatment (TCT) of single-dose azithromycin with coverage of > 90%.The efficacy of the strategy to reduce the levels on infection has been demonstrated previously in isolated island communities in the Pacific region. We aimed to determine the efficacy of a single round of TCT with azithromycin to achieve a decrease in yaws prevalence in communities that are endemic for yaws and surrounded by other yaws-endemic areas. METHODS: Surveys for yaws seroprevalence and prevalence of skin lesions were conducted among schoolchildren aged 5-15 years before and one year after the TCT intervention in the Abamkrom sub-district of Ghana. We used a cluster design with the schools as the primary sampling unit. Among 20 eligible primary schools in the sub district, 10 were assigned to the baseline survey and 10 to the post-TCT survey. The field teams conducted a physical examination for skin lesions and a dual point-of-care immunoassay for non-treponemal and treponemal antibodies of all children present at the time of the visit. We also undertook surveys with non-probabilistic sampling to collect lesion swabs for etiology and macrolide resistance assessment. RESULTS: At baseline 14,548 (89%) of 16,287 population in the sub-district received treatment during TCT. Following one round of TCT, the prevalence of dual seropositivity among all children decreased from 10.9% (103/943) pre-TCT to 2.2% (27/1211) post-TCT (OR 0.19; 95%CI 0.09-0.37). The prevalence of serologically confirmed skin lesions consistent with active yaws was reduced from 5.7% (54/943) pre-TCT to 0.6% (7/1211) post-TCT (OR 0.10; 95% CI 0.25-0.35). No evidence of resistance to macrolides against Treponema pallidum subsp. pertenue was seen. DISCUSSION: A single round of high coverage TCT with azithromycin in a yaws affected sub-district adjoining other endemic areas is effective in reducing the prevalence of seropositive children and the prevalence of early skin lesions consistent with yaws one year following the intervention. These results suggest that national yaws eradication programmes may plan the gradual expansion of mass treatment interventions without high short-term risk of reintroduction of infection from contiguous untreated endemic areas.

Bibliometrics of Tunisian publications in preventive and community medicine, indexed in the Medline database (1975-2014).

INTRODUCTION: With the aim of rebuilding the memory of the specialty of Preventive Medicine and Community Medicine (MPC) in Tunisia, through its indexed scientific publications, the objective of this work was to describe the thematic and methodological profile of indexed scientific research, of this specialty over four decades. METHODS: This is a descriptive bibliometric study of MPC articles, indexed in the Medline database over a 40-year period (1975-2014), and based on their Medline Material Safety Data Sheets (MSDS). All articles of which the first and / or last authors were MPC university hospital teachers, in one of Tunisia's four faculties of medicine, were included. The themes of the publications were defined through the major keywords (Majr), and categorized according to the following five groups: "non-communicable diseases", "communicable diseases", "violence and traumatisms", "management of health services" and "Research and pedagogy". RESULTS: Among 1664 articles captured by the Medline-based documentary request, 594 had as their first authors, teachers of the MPC specialty and 365 articles were eligible for study. The productivity of the specialty of MPC increased from 29 publications between 1975 and 1984, to 167 between 2005 and 2014. The magazine "La Tunisie Médicale" published 37.6% of the articles of this specialty. Four out of ten MPC papers referred to hospital structures and 35% of them were cross-sectional observational studies. Over the decades, an increase in research topics related to "non-communicable diseases" versus "communicable diseases" has been noted in MPC. CONCLUSION: In Tunisia, research in MPC has been relatively prolific and globally consistent with the health needs of the population (impacted by the epidemiological transition). The orientation of research projects towards community-based proposals, of high methodological level and mobilizing multidisciplinary teams, would be necessary for the improvement of the quality and relevance of publications in MPC.

Obsessive compulsive inventory-child version (OCI-CV) in a Spanish community sample of children and adolescents / El Inventario Obsesivo Compulsivo-Versión niños (OCI-CV) en una muestra comunitaria de niños y adolescentes españoles

BACKGROUND: There is a growing interest in designing instruments to assess obsessive-compulsive symptoms in children. The Obsessive-Compulsive Inventory-Child Version (OCI-CV) has showed to be a valid in the evaluation of OCD in clinical and nonclinical populations. The main goal in this study was to analyze factor structure and psychometric properties of the OCI-CV in a community Spanish sample. METHOD: Data were collected from 914 children/adolescents with a mean age of 13.01 (SD = 1.96; Males = 51.3%). Exploratory factor analysis was carried out in order to study the internal structure of the OCI-CV Spanish version. Further, internal consistency, test-retest reliability, and convergent and discriminant validity of the total score and the factors obtained were examined. Finally, age and gender differences were also explored. RESULTS: Exploratory factor analysis yielded a similar structure to the original OCI-CV with the following six factors: Washing/Checking, Obsession, Ordering, Doubting, Neutralizing, and Hoarding. The internal consistency was strong for the total score, but moderate for the subscales. The Spanish version of the OCI-CV showed evidences of test-retest reliability and convergent and discriminant validity. CONCLUSION: The Spanish version of the OCI-CV is an instrument with adequate psychometric properties to assess obsessions and compulsions in Spanish children/adolescents

ANTECEDENTES: existe un creciente interés en el diseño de instrumentos que evalúen los síntomas obsesivo-compulsivos en niños. El Inventario Obsesivo Compulsivo-Versión para Niños (OCI-CV) ha demostrado ser válido para evaluar estos síntomas en población clínica y no clínica. El objetivo de este estudio fue analizar la estructura factorial y las propiedades psicométricas del OCI-CV en población española comunitaria. MÉTODO: se recogieron datos de 914 niños/adolescentes con una edad media de 13,01 años (DT = 1.96; 51.3% varones). Se realizó un análisis factorial exploratorio. Posteriormente se examinó la consistencia interna, la fiabilidad test-retest y la validez convergente y divergente de la puntuación total del instrumento y de los factores obtenidos. Finalmente, se comprobó la existencia de diferencias en función del sexo y la edad de los participantes. RESULTADOS: los resultados mostraron una estructura similar a la del OCI-CV original, compuesta por los siguientes factores: Lavado/Comprobación, Obsesión, Orden, Duda, Neutralización y Acumulación. La consistencia interna fue buena para la puntuación total, aunque moderada para las diferentes subescalas. La versión en castellano del OCI-CV mostró evidencias de fiabilidad test-retest y validez convergente y discriminante. CONCLUSIONES: OCI-CV es una herramienta con adecuadas propiedades psicométricas para la valoración de obsesiones y compulsiones en niños/adolescentes españoles

Medication use is associated with fatigue in a sample of community-living individuals who have a spinal cord injury: a chart review.

OBJECTIVES: To investigate the relationship between medications known to cause fatigue in spinal cord injury (SCI) and fatigue severity and to describe the pattern of prescription of these medications. STUDY DESIGN: Retrospective chart review. SETTING: GF Strong Rehabilitation Centre, Vancouver, British Columbia, Canada. METHODS: Medical charts of 136 individuals admitted to the GF Strong Outpatient SCI Program between December 2004 and May 2007 were reviewed. Data collected included information on medications, clinical and demographic characteristics and Fatigue Severity Scale (FSS) scores. Multiple linear regression techniques were used to analyse the data. RESULTS: Fifty-two percent of the subjects had clinically relevant fatigue. As a group, the subjects were taking 147 different medications; 41/147 medications were identified as causing fatigue. The two most commonly prescribed categories of medications were antispasticity medications (75 subjects) and analgesic medications (61 subjects). Although several variables were found to contribute to the FSS scores including the use of fatigue-causing medications, the presence of pain (7.6% of variance) and the use of fatigue-causing analgesics (4.2% of variance) explained the most variance in the scores. CONCLUSION: Fatigue is prevalent in outpatients with SCI. Fatigue-causing medications contribute to a higher FSS score. Clinicians treating persons with SCI should be aware that fatigue is a common and significant problem. Clinicians should be aware that fatigue may be exacerbated by the use of medication and should enquire about the effects of medication on fatigue when assessing and prescribing new medications.

Etiología de la infección urinaria baja adquirida en la comunidad y resistencia de Escherichia coli a los antimicrobianos de primera línea. Estudio nacional multicéntrico / Etiology of community-acquired lower urinary infections and antimicrobial resistance of Escherichia coli: a national surveillance study

Fundamento y objetivo: Las crecientes tasas de resistencia que muestran los patógenos urinarios representan un grave problema. El objetivo de este estudio ha sido realizar en España un seguimiento de la etiología de las infecciones urinarias de vías bajas de adquisición comunitaria y de la resistencia de Escherichia coli a los antimicrobianos de primera línea. Material y método: Se trata de un estudio multicéntrico realizado entre febrero y junio de 2006 en 15 laboratorios de microbiología localizados en 9 comunidades autónomas. Resultados: Se obtuvieron 3.109 uropatógenos. E. coli fue el más frecuente (70,8%), seguido de Klebsiella spp. (6,8%), Proteus spp. (6,6%) y Enterococcus spp. (5,5%). La resistencia de E. coli fue del 1,7% para fosfomicina, del 3,8% para nitrofurantoína, del 6,9% para cefixima, del 8,1% para amoxicilina-ácido clavulánico, del 8,9% para cefuroxima y del 23,9% para ciprofloxacino. El 5,2% produjo betalactamasas de espectro extendido (BLEE). La resistencia de E. coli a ciprofloxacino fue inferior en menores de 40 años (el 6,7 frente al 33,9% en mayores de 60 años; p < 0, 001) y en algunas áreas geográficas (el 12,5% en Galicia frente al 37,3% en Valencia). La producción de BLEE fue más elevada en mayores de 60 años (el 79,1 frente al 7% en menores de 40 años; p < 0, 001) y presentó importantes variaciones geográficas (un 18,4% en Valencia y un 0,8% en Galicia). El 68,6% de E. coli productor de BLEE fue resistente al cotrimoxazol y un 72,2% a ciprofloxacino, frente al 10,6% a nitrofurantoína y el 1,9% a fosfomicina. Conclusiones: Las tasas de resistencia y de resistencias cruzadas que se evidencian en este estudio representan un grave problema que obliga a reevaluar el tratamiento empírico de las infecciones urinarias de vías bajas (AU)

Background and objetives: The increasing rates of resistance exhibited by uropathogens represent a serious problem. The aim of this study was to determine, in Spain, the etiology of community-acquired lower urinary infections and antimicrobial resistance of Escherichia coli isolates. Methods: Prospective multicenter study conducted between February and June 2006, in 15 microbiology laboratories located in 9 autonomous regions. Results: A total of 3,109 isolates were recovered. E. coli was the most frequent (70.8%), followed by Klebsiella spp (6.8%) Proteus spp (6.6%), and Enterococcus spp (5.5%). The resistant rate of E. coli for phosphomycin was 1.7%, 3.8% nitrofurantoin, 6.9% cefexime, 8.1% amoxicillin-clavulanic, 8.9% cefuroxime, and 23.9% ciprofloxacin. The 5.2% were extended-spectrum beta-lactamase (ESBL)- producing microorganisms. Resistance of E. coli to ciprofloxacin was lower in people younger than 40 years (6.7% vs 33.9% in > 60, p < 0.001), and in some regions (12.5% in Galicia vs 37.3% in Valencia). ESBL-producing E.coli was higher in people older than 60 years (79.1% vs 7% in < 40, p < 0.001), and exhibited geographic variations (18.4% in Valencia, 0.8% in Galicia). The 68.6% of ESBL-producing E.coli were resistant to cotrimoxazole, 72.2% to ciprofloxacin vs 10.6% to nitrofurantoin and 1.9% to phosphomycin. Conclusions: The increasing rates of resistance and cross-resistance of this study make evident a real problem that strengthens the need for a reevaluation of the empiric treatment of lower urinary infections (AU)

Shifts in the use of population health, health promotion, and public health: a bibliometric analysis.

OBJECTIVE: Bibliometric analysis can be used to objectively compare the usage of terms over time. The purpose of this research was to compare the use of population health, health promotion, and public health using bibliometric indicators of the published literature. METHODS: Bibliometric indicators, such as scientific productivity and the overlap between the terms, were analyzed in the Web of Science. Indexing of population health, health promotion, and public health was explored in MEDLINE, CINAHL, and EMBASE. RESULTS: The most productive country in population health was Canada, while the most productive country in health promotion and public health was the United States. The number of published articles using the public health term was surpassed by health promotion around 1990. Both were surpassed by population health around 2000. Population health was the only concept which lacked an index term in all three databases. DISCUSSION: There has been a shift in the usage of public health, health promotion, and population health concepts over time. Country analysis revealed that Canadian researchers are leaders in population health, while researchers based in the United States are leaders in public health and health promotion. This may indicate differences rooted in the social, historical and economic traditions. Although the publication rate of articles described as 'population health' research is increasing, it is lacking an index term across major electronic databases. We suggest that without timely acceptance of terms, new concepts that represent different ways of thinking about health may be limited, delayed or glossed over.

Prenatal ultrasound: a tale of two cities.

At the beginning of the 21st century, community-based physicians have a technology which is safe, noninvasive and relatively inexpensive. It allows immediate access to visual data inside the body for the evaluation of health and disease. Prenatal ultrasound is vital for the efficient provision of preventive care even in community health centers, where physicians may not be the delivering physicians. To assess the frequency of this diagnostic technology, a longitudinal study of 36 months tabulated prenatal ultrasound scans performed in two community-based offices providing generalist healthcare from 2001 through 2003. Between the two offices, 68,938 patients were seen, 679 deliveries were attended and 1,286 medically indicated prenatal ultrasound examinations were performed. Prenatal ultrasound scans--compared to other common office procedures, such as electrocardiograms, chest radiographs, circumcisions, blood sugar checks, Papanicolaous and colposcopies--emerged as one of the most frequently preformed diagnostic tests in the office. Based on these results, medical educators preparing generalist physicians for community medicine may want to consider some training in prenatal ultrasound. Future research can confirm the generalizability of the findings of this pilot study in two urban health centers.

[The primary care service portfolio: significance and comparability]. / La cartera de servicios en atención primaria: significado y comparabilidad.

OBJECTIVES: To clarify the significance of the primary care (PC) range of services (RS) output, to determine the factors affecting it and to establish a method to compare the effort or work-load of primary care team (PCT) professionals at HCs. DESIGN: Transversal, descriptive study of the RS in 2003. Calculation of the method of work load attained by weighted professional. SETTING: Primary care, IMSALUD Area 1, Madrid, Spain. MAIN MEASUREMENTS: The RS output correlated significantly and negatively with the family medicine ratios, nursing ratios, and income per head. The RS output at the PCTs ranged between 89.32% and 36.27%; in the method proposed, it range between 9326 and 6167 units/weighted professional. CONCLUSIONS: The calculation of the current RS output measures the equity of access of the population to the various services of the RS and their coverage, but it does not allow comparison of the work of different PCTs, as it does not take into account the effect of the population on coverage or the size of the work-force that delivers these products. Another calculation is needed, such as the work load attained by weighted professional (work units in PC per professional), that obtains fewer differences in results between professionals.

Frequency of alcohol use and obesity in community medicine patients.

BACKGROUND: Obesity is an important public health problem. However, the effects of alcohol use on the risk for obesity have not been thoroughly explored. This study focuses on how frequency of alcohol use is related to the risk of obesity in a community medicine clinic population. METHODS: This study used a cross-sectional survey to test the hypothesis that obesity (BMI > 30) is associated with alcohol use. The convenience sample was drawn from three clinics that primarily serve low-income populations. Independent variables included frequency of alcohol use, frequency of binge drinking, demographic characteristics, health behaviors and health status. RESULTS: In comparison to non-drinkers, people who consumed alcohol 3 or more days per month had lower odds of being obese (Adjusted Odds Ratio = .49, p < .04). As expected, there was a significant association between watching eight or more hours of television per day and obesity (AOR = 2.34, p < .01). CONCLUSION: More frequent drinking and less television time are independently associated with reduced odds of obesity in this sample of community medicine patients. Additional research is needed to isolate casual mechanisms.

More physicians in public health: less public health work?

AIM: The object was to assess changes in work priorities in local public health medicine in Norway over the period from 1994 to 1999. METHODS: Two cross-sectional studies were undertaken of physicians working in local public health medicine in all Norwegian municipalities, using a postal questionnaire. RESULTS: Half of the physicians working in public health in 1999 were recruited after 1994. Although the number of physicians working in public health increased from 505 in 1994 to 555 in 1999 (10%) an estimation of the total weekly hours worked decreased by 3.7% from 8,715 hours in 1994 to 8,386 hours in 1999. The vast majority of physicians worked in combined posts (87%), and they reduced their engagement in public health by 2.6 hours on average from 1994 to 1999. The reduction depended on remuneration model, speciality in community medicine, and municipality size. CONCLUSIONS: Local public health in Norway was under pressure in the 1990s. For public health physicians, preventive medicine lost out to clinical work. No promising signals of change in the professional or political framework or in incentives for public health work are seen.

Early reversal of pediatric-neonatal septic shock by community physicians is associated with improved outcome.

OBJECTIVE: Experimental and clinical studies of septic shock support the concept that early resuscitation with fluid and inotropic therapies improves survival in a time-dependent manner. The new American College of Critical Care Medicine-Pediatric Advanced Life Support (ACCM-PALS) Guidelines for hemodynamic support of newborns and children in septic shock recommend this therapeutic approach. The objective of this study was to determine whether early septic shock reversal and use of resuscitation practice consistent with the new ACCM-PALS Guidelines by community physicians is associated with improved outcome. METHODS: A 9-year (January 1993-December 2001) retrospective cohort study was conducted of 91 infants and children who presented to local community hospitals with septic shock and required transport to Children's Hospital of Pittsburgh. Shock reversal (defined by return of normal systolic blood pressure and capillary refill time), resuscitation practice concurrence with ACCM-PALS Guidelines, and hospital mortality were measured. RESULTS: Overall, 26 (29%) patients died. Community physicians successfully achieved shock reversal in 24 (26%) patients at a median time of 75 minutes (when the transport team arrived at the patient's bedside), which was associated with 96% survival and >9-fold increased odds of survival (9.49 [1.07-83.89]). Each additional hour of persistent shock was associated with >2-fold increased odds of mortality (2.29 [1.19-4.44]). Nonsurvivors, compared with survivors, were treated with more inotropic therapies (dopamine/dobutamine [42% vs 20%] and epinephrine/norepinephrine [42% vs 6%]) but not increased fluid therapy (median volume; 32.9 mL/kg vs 20.0 mL/kg). Resuscitation practice was consistent with ACCM-PALS Guidelines in only 27 (30%) patients; however, when practice was in agreement with guideline recommendations, a lower mortality was observed (8% vs 38%). CONCLUSIONS: Early recognition and aggressive resuscitation of pediatric-neonatal septic shock by community physicians can save lives. Educational programs that promote ACCM-PALS recommended rapid, stepwise escalations in fluid as well as inotropic therapies may have value in improving outcomes in these children.

A computer program to fit a family and community medicine set-up.

A local Personal Computer (PC) network program has been designed to improve training and patient care in Family and Community Medicine set-up. The software was designed to cope with the different clinical, preventive, promotive and statistical programs of the teaching set-up. This system serves multiple levels of patient priority, assigning each patient to an individual health team staff. The present software is designed to be used for IBM PC Pentium hardware with a Window's environment. This article is a summary of the main features of the program and its applications. Such a program is essential in comprehensive health care-related decision-making and in improving patient care. The authors recommend using similar programs in family practice and in primary health care centers.

Assessing hypertension management in the community: trends of prevalence, detection, treatment, and control of hypertension in the MONICA Project, Augsburg 1984-1995.

OBJECTIVE: To assess trends in prevalence and detection, treatment and control of hypertension in a German population between 1984 and 1995. SETTING AND PARTICIPANTS: Independent random samples of the population were examined in cross-sectional surveys with identical methods in 1984/85 (age range 25 to 64 years, n = 4022 participants), 1989/90 (age range 25 to 74 years, n = 4940) and 1994/95 (age range 25 to 74 years, n = 4856). MAIN OUTCOME MEASURES: Prevalence of hypertension and proportions of hypertensives detected, treated and controlled. Hypertension was defined as blood pressure above 140/90 mm Hg or taking antihypertensive medication. RESULTS: The prevalence of hypertension did not change significantly over the 10 years (25--64 years, age-standardised 1984/85: 37.8% in men and 24.6% in women; 1994/95: 39.3% and 24.8%, respectively). Rates of detection, treatment and control of hypertension did not change much either. Of all hypertensives in 1994/95, 54% were detected in men and 64% in women, the treatment rates were 23% and 32%, and the proportions of those with controlled hypertension (below 140/90 mm Hg with treatment) were as low as 7% and 13%, respectively. Rates were higher in the older age groups, however, control rates never exceeded 20% at any age. CONCLUSIONS: Despite considerable changes in the pharmacological treatment of hypertension there was a disappointing stagnation with regard to the management of this important risk factor in the community. The reasons for this unfavourable trend need clarification and appropriate public health action. Journal of Human Hypertension (2001) 15, 27-36

Validation of death certificate diagnosis of out-of-hospital sudden cardiac death.

The validity of death certificate diagnosis of out-of-hospital sudden cardiac death (OOH-SCD) was studied among 108,676 30- to 74-year-old residents in 5 Minnesota communities using 6-year mortality data (1985 to 1990). Among 4,244 total deaths, location of death was listed on the certificate as out of hospital in 2,035 cases. Of those, 911 were judged not to have OOH-SCD because they had actually been admitted to the hospital or were noncardiovascular deaths. Among the remaining 1,124, 254 were diagnosed as OOH-SCD using a thorough, physician-based procedure that used clinical records, autopsy reports, and an informant (next-of-kin) interview. We used only death certificate information to define OOH-SCD simply and inexpensively as ICD-9 code 427.5 (cardiac arrest) plus location of death listed as out-of-hospital. Compared with the physician diagnosis, sensitivity was only 24%, whereas specificity was 85%. When the definition of OOH-SCD was expanded to include ICD codes 410-414 (acute myocardial infarction and chronic coronary artery disease), sensitivity improved to 87%, whereas specificity became 66%. However, even with this higher sensitivity and specificity, only 27% of the cases labeled OOH-SCD by death certificate agreed with the physician diagnosis. Death certificate diagnosis of OOH-SCD included many erroneous cases, and may not have been suitable for study of etiologic factors, such as cardiac dysrhythmias. Death certificate diagnosis may be useful to assess population time trends in OOH-SCD, provided that misclassification (false-positive rate) remains constant over time.

Assessment of occupational exposures in community-based case-control studies.

Assessing occupational exposures in community-based studies is a challenge for investigators because there are no standardized or validated approaches for collecting information regarding occupational history. The strengths and limitations of the methods available for assessing occupational exposures are reviewed. In community-based case-control studies, the prevalence of most chemical agents is low. The common sources of misclassification in these studies are addressed, as are strategies for dealing with misclassification bias. Methods to assess the presence and magnitude of differential reporting by cases and controls are outlined, together with analytic strategies to improve the classification of occupational exposures.
