To determine whether patient access to secure patient-physician messaging affects annual adult primary care office visit and documented telephone contact rates. Retrospective cohort and matched-control studies with pre-post analysis. The cohort study sample included 4686 adult members of Kaiser Permanente Northwest (KPNW) who had been registered KP...

To evaluate the effect of implementing comprehensive, integrated electronic health record systems on use and quality of ambulatory care Retrospective, serial, cross sectional study. Colorado and Northwest regions of Kaiser Permanente, a US integrated healthcare delivery system. 367,795 members in the Colorado region and 449,728 members in the North...

Further evidence in favor of the clinical IT business case is set forth in Kaiser Permanente's cost/benefit analysis for an electronic hospital information system. This article reviews the business case for an inpatient electronic medical record system, including 36 categories of quantifiable benefits that contribute to a positive cumulative net ca...

This paper describes Kaiser Permanente's (KP) enterprise-wide medical terminology solution, referred to as our Convergent Medical Terminology (CMT). Initially developed to serve the needs of a regional electronic health record, CMT has evolved into a core KP asset, serving as the common terminology across all applications. CMT serves as the definit...

Article
The purpose of this study was to determine whether children hospitalized with a primary diagnosis of infection were more likely than matched controls to have had a diphtheria-tetanus toxoids-pertussis immunization in the 30 days before hospitalization of the case. Cases were less likely than controls to have received an immunization (P = 0.003). Th...
Article
Minor local reactions and subcutaneous abscesses following diphtheria, tetanus and pertussis immunization have been attributed to vaccine left in the subcutaneous needle path from vaccine coating the needle. Various syringe preparation techniques have therefore been advocated to prevent reactions. To evaluate these recommendations we compared rates...
Article
As a consequence of a broader epidemiologic study of toxic shock syndrome (TSS) (1), it became clear that many hospitalized cases of TSS could be related to diseases, both major and minor, involving Staphylococcus aureus infection. We, therefore, investigated the incidence of TSS in hospitalized patients with suspected or proven S. aureus infection...
Article
Several clinical definitions of toxic shock syndrome have been proposed and used in extensive epidemiologic and clinical studies. Most of these definitions suggest (but usually do not require) that there be sufficient laboratory studies to exclude other potentially similar syndromes. Simplified definitions which broaden the spectrum of toxic shock...
Article
Medical records for hospitalized patients between 30 days and 30 years of age at two hospitals, one in each of two Colorado counties, were reviewed for possible cases of toxic shock syndrome conforming to one or both of two clinical case definitions. Patients with toxic shock syndrome were detected in each year from 1970 through 1982. Fifty patient...
Article
A comparative retrospective analysis of 45 patients with toxic shock syndrome (TSS) was designed to evaluate the effect of corticosteroid therapy on outcome. All patients satisfied the collaborative strict case definition for TSS, were hospitalized, had shock or postural hypotension, had a potential focus of Staphylococcus aureus infection, and rec...
Article
Eight children aged 10 years or less had toxic shock syndrome, and medical records were reviewed for seven of them. There were four boys and three girls, ranging in age from 5 5/12 to 10 8/12 years; all seven met the Centers for Disease Control case definition of toxic shock syndrome. One boy died. The illness was generally characterized by fever,...
Article
An outbreak of group A beta-hemolytic streptococcal infections involving three parturients, three newborns, and a nursery RN is reported. Six of six organisms available for serotyping were M-untypable, T-11, serum opacity reaction-negative. Propagation of the outbreak may have been fostered by the common use of a single sitz bath, although the evid...

In early 1979, an official of an Illinois hospital reported an increase in the number of patients from whom Mycobacterium avium complex recently had been recovered. Over the preceding 3 years specimens from a total of 51 patients were culture positive for M. avium complex: 7 in 1976, 8 in 1977, and 36 in 1978. Nine of 10 serotyped isolated were ser...
Article
An 11 month-old infant had meningitis caused by a strain of Streptococcus pneumoniae, serotype 6b, resistant to penicillin, chloramphenicol, and several other antimicrobials. The minimum inhibitory concentrations (MIC) by agar dilution were 1.0 microgram/ml for penicillin and 16 microgram/ml for chloramphenicol. The infant did not respond to high-d...
Article
Legionella pneumophila serogroup 6 was isolated from nine of 16 shower heads in a Chicago hospital ward where three patients had contracted Legionnaires' disease caused by serogroup 6 L. pneumophila. Each patient had showered there 2 to 10 days before the onset of disease symptoms. We also isolated the bacteria in two other hospitals, and found the...
Article
Sixty male survivors of acute myocardial infarction in the week after the Chicago blizzard of Jan 15, 1979, were matched by hospital and sex with 60 myocardial infarction survivors from a week without snowfall to determine whether a history of previous heart disease or of cardiac risk factors increased the risk of a postblizzard myocardial infarcti...
Article
In response to public concerns, 165 Meo Laotians had stools screened for intestinal parasites by the Illinois Department of Public Health. One hundred twenty-nine had at least one pathogenic parasite detected. Hookworm was detected most frequently, followed by Giardia lamblia, Trichuris trichiura, and Ascaris lumbricoides. Hookworm and overall infe...

To the Editor.— In his editorial lament, "Medical Education" (241:1040, 1979), John P. Callan, MD, touched on a problem of great interest to me. His solution, broadening the scope of continuing medical education courses to include arts and humanities, is a classic example of retrofitting rather than attacking a problem at its source.Most medical s...
