Correlation between standardized death rate for area and LA(50).

In order to investigate the relationship between standardized death rate for area and 50% mortality rate for burn area (LA(50)), correlation analysis, curve estimation and linear regression were performed with the variables. The results showed that: (1) there was a similarity in sort order of standardized death rate in control groups of samples, compared with the experimental group; (2) there were significant differences between the sort order from low to high mortality rate of standardized death rate in control groups for burn area, compared with the sort order in the experimental group; (3) there was a similarity (P<0.05) in low to high sort order for standardized death rate compared with high to low sort order for LA(50) in the experimental group; and (4) there was an extraordinarily significant correlation (P<0.0001) between linear regression analysis and curve estimation for the standardized death rate and LA(50) using a Pearson correlation. The observation that there was a significant relation between the sort orders in standardized death rate and LA(50) shows that the standardized death rate for area can reflect accurately mortality in each of samples.

Comparable results between standardization methods and regression analysis in predicting mortality rate among samples with burns.

This report suggests an alternative statistical model for estimating the mortality rate of samples of patients with burns. Three direct standardization methods were applied to nine samples (48,379 patients) selected randomly from the medical literature, and compared with the technique of three regression models, The results showed the similar mortality rates in these samples using the three different methods for standardization in comparison to the rates of LA(50) using three regression models. Of the different standardization methods used to measure the of mortality rate, standardization of death rate for age and area burned may be the best method to objectively evaluate the results of burns care, if combined with LA(50) using regression analysis. Furthermore, the values of LA(50) and 95% Cl in a sample are changed with different regression models. It is necessary to specify the regression model, 95% Cl or correlation coefficient of LA(50) in probit analysis or linear regression, respectively, when LA(50) of one sample is compared with that of another.

Mortality rates among 5321 patients with burns admitted to a burn unit in China: 1980-1998.

A retrospective study was conducted on 5321 burn patients hospitalized in a burn center in Jinzhou, China during the period 1980-1998. Of the 5321 patients, 57.8% were between 15 and 44 years old and 3.4% were > or =60 years old. Ninety-six percent had burns covering less than half of body surface area and 31.7% had only full thickness skin burn. The number of patients in the 1990s was three times that of the 1980s. Overall mortality rate was 0.86%. LA(50) for total body burn area (TBSA) and only full thickness skin burn (FTSB) was 94 and 87%, respectively. The high survival rate, may relate primarily to the low percentages of older patients and of patients with severe burns. Inhalation injuries, infection and MOD are the main causes of deaths in our patients and would be key targets to improve clinical care and in future study.
