Notes

The formula for costs is number of cases x cost per case. Because the cost figures are derived from formulas, some data limitations should be noted.

The number of cases is based on the population attributable risk (PAR). The PAR formula is: [Prevalence x (Relative Risk – 1)/Prevalence x (Relative Risk – 1) + 1] x 100, where prevalence is the percentage of use in the general population and relative risk is an individual substance abuser’s increased risk of contracting a disease relative to that of a non-substance abuser. The formula yields the number of cases related to substance abuse.

The number of cases was multiplied by 12.65 percent, the proportion of persons age 65 and over, to yield the number of cases among older persons. Cost per case is determined based on the average number of hospital days to treat a disease multiplied by the cost per day.

*Assaults by other or unspecified means and assaults by cutting and piercing instrument; does not include fight, brawl, or rape.

Figures for chronic obstructive pulmonary disease (COPD) are the same as for acute respiratory distress syndrome. COPD was not noted in the literature, but risks would be similar as COPD can lead to episodes of respiratory distress.

The number of cases of infective endocarditis is based on the population attributable risk (PAR) for injecting drug use but is consistent with research indicating that excess alcohol consumption significantly increases the risk of infective endocarditis. Although no relative risk figures were available, the relative risk figure corresponding to the prevalence and PAR would be approximately 1.8, a conservative number given the high risk of heart attack (myocardial infarction).

§Oral leukoplakia is used as a proxy measure for alcohol-related dental problems. Literature is sparse regarding the effects of alcohol on dental health, such as edentulousness, gingivitis, and decay.

**No. of cases = Total injuries x % of workers 65+.
