Evaluation of alternate messages on an electronic message strip to recruit subjects to a smoking-cessation program.

The authors previously published details of a method to evaluate the effectiveness of electronic message strips in recruiting subjects to a smoking-cessation program. They now report data suggesting that a shorter, more negative message yields better results than a longer, more positive message. The data also show that this approach increases the number of subjects who enroll in a smoking-cessation program and the number of subjects who actually quit smoking.

Evaluation of an electronic message strip to recruit smokers to a smoking cessation program.

Knowledge of outcome is essential when analyzing effectiveness of educational programs. Although quantitative data can be analyzed more rigorously than other forms of data, quantitation of behavioral processes is often difficult. To promote our smoking-cessation program we designed a method that relies on electronic message strips and a dedicated telephone line capable of providing quantitative outcome information. This approach appears quite versatile and shows that the electronic message strip is a surprisingly ineffective method of enlisting subjects into a smoking-cessation program in our hospital.

Evaluation of surgical services in a large university-affiliated VA hospital: use of an in-house-generated quality assurance data base.

In this era of occurrence screening, increased documentation of surgical resident supervision, and overall efforts to alter quality of patient care through increased documentation, an in-house quality assurance data base can greatly facilitate these activities. To establish a data base, 6241 operative procedures over a 15-month interval were logged into a StatView II Database using the patient's name and record number, diagnosis, and operative information available from the standard operation report worksheet. Additional information, including the name of the supervising staff and level of supervision, had also been recorded concurrently on this form. Each month, after this demographic information has been entered into the data base for each surgical service, it is reviewed, ensuring 100% surveillance of all cases. The subsequent morbidity and mortality (M & M) information is then added to the data base. Using the contingency table option of the StatView II Database, quarterly and annual reviews have been done to study individual services, types of cases, staff attending, individual supervision, levels of staff involvement, and incidence of complications. Our Surgical Service has reported an overall morbidity of 306 cases (4.9%) and mortality of 71 (1.14%). Average numerically coded levels of resident supervision have been compiled with regard to individual services and staff surgeons. This data base has proved helpful in the recredentialling process of our surgical staff, resident logs, identification of necessary reviews of certain case types, and formation of a computerized operative log.

Diagnosis of coronary artery disease with 201Tl. Computer analysis of myocardial perfusion images.

The diagnostic sensitivity of visually interpreted and computer-analyzed 201Tl myocardial perfusion images was compared to that of exercise electrocardiograms in 8 angiographically normal subjects and 24 patients with significant coronary artery disease. Visual interpretation was not significantly better than exercise ECGs. An index of perfusion homogeneity, derived from computer analysis of the 201Tl images, was more sensitive than visual interpretation (79% vs. 58%) and much more sensitive (p less than 0.05) than the exercise ECG (79% VS. 46%). The best overall sensitivity (88%) and specificity (75%) were achieved by combining computer analysis with exercise electrocardiography. The computer also permits enhanced detection of subtle perfusion changes which may not seem significant to the eye.
