The changing trends of uterine cancer and cytology: a study of morbidity and mortality trends over a twenty year period.

Data on squamous carcinoma of the cervix from a 20 year study period (1955 to 1974) in metropolitan Toledo revealed a 66% reduction of the average annual age-adjusted incidence rate and a 61% reduction in death rate of cervical squamous carcinoma when the first time period (1955 to 1958) was compared with the last time period (1971 to 1974). The decrease for both morbidity and mortality rates was more pronounced in women age 50 years and younger. The age-adjusted death rate during this study period revealed 15.5/100,000 for black women and 8.7/100,000 for white women. The reduction in death rate of 83% in black women is more prominent than 54.5% in white women. The decrease in both morbidity and mortality for cervical squamous carcinoma has a close relation to cytologic screening activity. The factors of age and race, probably related to socioeconomic status, are two known determinants of risk for cervical squamous carcinoma. Data for endometrial carcinoma during this study period revealed 15.5/100,000 women in the average age-adjusted incidence and an increase of 13.8% in average yearly rates when the first time period (1955 to 1958) were compared with the last time period (1971 to 1974). The peak age was 60 to 64 years old in the first time period and shifted to 70 to 74 years old in the last time period. The trend in metropolitan Toledo is comparable to that of Louisville, Kentucky. The mass cytologic screening program which contributed to a remarkable reduction in morbidity and mortality for the cervical squamous carcinoma, did not have any beneficial effect on endometrial carcinoma.

Evaluating inpatient costs: the staging mechanism.

Inpatient records at a short-term hospital over two years were analyzed according to the stage or degree of severity of their discharge diagnosis to examine their utilization of services. Patients with a more severe disease stage for surgical and medical conditions generated substantially higher total charges, ancillary charges, and had longer lengths of stay. At the 75th percentile (representing that value at which three-quarters of the cases fall below it in magnitude), increases in total charges from Stage I to II for ulcer of stomach, appendicitis, and diverticulitis were 103, 168, and 110 per cent, respectively. Ancillary charges for these diseases showed even greater increases, 167, 200, and 160 per cent, respectively. Components of ancillary charges revealed similar trends. The results suggest that a twofold review mechanism incorporating length of stay and charges, using the staging technique, would make the review procedure more discriminating in identifying cases appropriate for review.

Teaching students the relationship between quality and cost of medical care.

The usefulness of hospital charges as a means of teaching medical students the relationship between the quality of the cost of medical care provided by primary care physicians (internists and family physicians) is presented. The comparative role of these two types of primary care physicians as "generators of costs" is described. The cost of hospital care provided by primary care physicians is also compared with the cost of care provided by the cardiologist, a prototype of the highest quality of secondary and tertiary care for cardiovascular diseases. Data indicate that internists generated hospital costs that were consistently higher than family physicians. Moreover, a comparison of costs generated by internists, family physicians, and cardiologists in managing patients with cardiovascular diseases revealed that cardiologists generated lower costs than the other two types of specialists. It is believed that case studies such as this will provide evidence that will enable undergraduate medical students to reflect upon their own attitudes toward their developing role as "generators of cost".
