Comparative Study
Sepsis syndrome and associated sequelae in patients at high risk for gram-negative sepsis.
We conducted a prospective surveillance study of 80 hospitals across the United States to determine the incidence of sepsis syndrome and its associated sequelae in hospitalized patients over age 18 years who were administered antibiotics for suspected or documented gram-negative infection. A sample of 1754 hospitalized patients were followed from onset of antimicrobial therapy to discharge or death. Mortality rates (MR) varied depending on the suspected source of sepsis syndrome. ⋯ More than two complications occurred in 65.2% of patients under age 60 years (MR 31%), 40.8% of those age 60-80 (MR 42%), and 35.6% of patients older than 80 years (MR 33.3%, p > 0.05). Various patient populations had significant differences in both the incidence of the syndrome and its complications, and consequent mortality. Perhaps morbidity as well as mortality should be used as outcomes when testing the efficacy of innovative therapies for sepsis.

Randomized Controlled Trial Comparative Study Clinical Trial
The effect of isoflurane versus balanced anesthesia on rocuronium's pharmacokinetics and infusion requirement.
To compare the effects of two anesthetic techniques, balanced and isoflurane anesthesia, on the response to an intubating dose and an infusion of rocuronium, and on rocuronium's pharmacokinetics. ⋯ The similarity of response to an intubating dose and an infusion of rocuronium suggests that clinicians need not alter the dose or rate of rocuronium administration during isoflurane anesthesia with a of duration less than 1 hour. However, the greater clearance of rocuronium, in light of the similarity of infusion requirements, suggests that isoflurane potentiates rocuronium compared with balanced anesthesia.

Comparative Study
Is antidepressant use changing? Prevalence and clinical correlates in two New England communities.
We attempted to determine whether the prevalence of antidepressant use had increased in population-based samples between 1981 and 1993, and compared the characteristics of antidepressant users and nonusers. Data were derived from six biennial, random sample, cross-sectional household surveys conducted between 1981 and 1993 in two southeastern New England communities. ⋯ Comorbid conditions and concurrent drug therapy were present more frequently among users. The overall prevalence of antidepressant use per 1000 population increased from 7.8 (95% confidence interval 4.3, 11.3) in 1981-1982 to 31.4 (95% CI 23.9, 38.9) in 1992-1993, especially among women and respondents between ages 40 and 59 years.
