Child and family safety device affordability by country income level: an 18 country comparison.

OBJECTIVE: To compare availability, urban price, and affordability of child/family safety devices between 18 economically diverse countries. DESIGN: Descriptive: urban price surveys by local safety organisations or shoppers. SETTING: Retail stores and internet vendors. MAIN OUTCOME MEASURES: Prices expressed in US dollars, and affordability measured by hours of factory work needed to buy a child safety seat, a belt-positioning booster seat, a child bicycle helmet, and a smoke alarm. RESULTS: Prices of child and family safety devices varied widely between countries but the variation for child safety seats and bicycle helmets did not relate strongly to country income. Safety devices were expensive, often prohibitively so, in lower income countries. Far more hours of factory work were required to earn a child safety device in lower income than middle income, and middle income than higher income, countries. A bicycle helmet, for example, cost 10 hours of factory work in lower income countries but less than an hour in higher income countries. Smoke alarms and booster seats were not available in many lower income countries. CONCLUSIONS: Bicycles and two-axle motor vehicles were numerous in lower and middle income countries, but corresponding child safety devices were often unaffordable and sometimes not readily available. The apparent market distortions and their causes merit investigation. Advocacy, social marketing, local device production, lowering of tariffs, and mandatory use legislation might stimulate market growth. Arguably, a moral obligation exists to offer subsidies that give all children a fair chance of surviving to adulthood.

Increased resource use associated with catheter-related bloodstream infection in the surgical intensive care unit.

HYPOTHESIS: Catheter-related bloodstream infection (CRBSI) in critically ill surgical patients with prolonged intensive care unit (ICU) stays is associated with a significant increase in health care resource use. DESIGN: Prospective cohort study. SETTING: Surgical ICU at a large tertiary care center. PATIENTS: Critically ill surgical patients (N = 260) with projected surgical ICU length of stay greater than 3 days. INTERVENTIONS: Central venous catheters were cultured for clinical suspicion of infection. MAIN OUTCOME MEASURES: Increases in total hospital cost, ICU cost, hospital days, and ICU days attributable to CRBSI were estimated using multiple linear regression after adjusting for demographic factors and severity of illness (APACHE III [Apache Physiology and Chronic Health Evaluation III] score). RESULTS: The incidence of CRBSI per 1000 catheter-days was 3.6 episodes (95% confidence interval [CI], 2.1-5.8 episodes). Microbiologic isolates were Gram-positive bacteria in 75%, Gram-negative bacteria in 20%, and yeast in 5%. After adjusting for demographic factors and severity of disease, CRBSI was associated with an increase of $56 167 (95% CI, $11 523-$165 735; P =.001) (in 1998 dollars) in total hospital cost, an increase of $71 443 (95% CI, $11 960-$195 628; P<.001) in ICU cost, a 22-day increase in hospital length of stay, and a 20-day increase in ICU length of stay. CONCLUSIONS: For critically ill surgical patients, CRBSI is associated with a profound increase in resource use. Prevention, early diagnosis, and intervention for CRBSI might result in cost savings in this high-risk population.
