Background: We sought to define the factors associated with house fires and
related injuries by analyzing the data from population-based surveillance.
Methods: For 1991 through 1997, we linked the following data for Dallas: re
cords from the fire department of all house fires (excluding fires in apart
ments and mobile homes), records of patients transported by ambulance, hosp
ital admissions, and reports from the medical examiner of fatal injuries.
Results: There were 223 injuries (91 fatal and 132 nonfatal) from 7190 hous
e fires, for a rate of 5.2 injured persons per 100,000 population per year.
Rates of injury related to house fires were highest among blacks (relative
risk, 2.8; 95 percent confidence interval, 2.1 to 3.6) and in people 65 ye
ars of age or older (relative risk, 2.6; 95 percent confidence interval, 1.
9 to 3.5). Census tracts with low median incomes had the highest rates of i
njury related to house fires (relative risk as compared with census tracts
with high median incomes, 8.1; 95 percent confidence interval, 2.5 to 32.0)
. The rate of injuries was higher for fires that began in bedrooms or livin
g areas (relative risk, 3.7); that were started by heating equipment, smoki
ng, or children playing with fire (relative risk, 2.6); or that occurred in
houses built before 1980 (relative risk, 6.6). Injuries occurred more ofte
n in houses without functioning smoke detectors (relative risk, 1.5; 95 per
cent confidence interval, 1.0 to 2.4). The prevalence of functioning smoke
detectors was lowest in houses in the census tracts with the lowest median
incomes (P<0.001).
Conclusions: Rates of injuries related to house fires are highest in elderl
y, minority, and low-income populations and in houses without functioning s
moke detectors. Efforts to prevent injuries and deaths from house fires sho
uld target these populations. (N Engl J Med 2001;344:1911-6.) Copyright (C)
