Awareness of and compliance with recommended screening procedures: a comparison of HMO and fee-for-service enrollees.

Managed care organizations, particularly HMOs, have emphasized disease prevention and early detection (screening) programs as a component of high-quality, cost-effective medical care. Studies in the 1980s found higher levels of utilization of screening by HMO enrollees compared with individuals enrolled in fee-for-service (FFS) plans, although this pattern is less clear in more recent reports. This paper reports on an analysis of a survey designed to determine awareness, compliance, and potential barriers to participating in common screening tests by adults living in Hillsborough County (greater Tampa), Florida. A random digit--dialing telephone survey of a stratified random sample of 500 adults over 18 years of age was conducted. Health plan enrollees were found to be younger, more likely to receive health insurance through an employer, and were more likely to have a regular source of health care. Few statistically significant differences, however, were detected in awareness of or compliance with recommended screening procedures between HMO and FFS enrollees in the study. Consistent with other recent research, these findings suggest that the changing nature of managed care, from traditional staff models toward IPA or network-hybrid models, has somewhat reduced HMOs' influence on prevention and screening services.

CATCH/IT: a data warehouse to support comprehensive assessment for tracking community health.

A systematic methodology, Comprehensive Assessment for Tracking Community Health (CATCH), for analyzing the health status of communities has been under development at the University of South Florida since the early 1990s. CATCH draws 226 health status indicators from multiple data sources and uses an innovative comparative framework and weighted evaluation criteria to produce a rank-ordered list of community health problems. CATCH has been applied successfully in many Florida counties; focusing attention on high priority health issues and measuring the impact of health expenditures on community health status outcomes. Previously performed manually, we are using information technology (IT) to automate the CATCH methodology with a full-scale data warehouse, user-friendly forms and reports, and extended analysis and data mining capabilities. The automated system, CATCH/IT, will reduce the time to prepare community health status reports from months to days. In this paper, we present the current status of the project, along with the principal research and development issues and future directions of the project.

The impact of legislatively imposed practice guidelines on cesarean section rates: the Florida experience.

Florida legislation implemented in the fall of 1992, unique in the nation, mandated that practice guidelines regarding cesarean section deliveries be disseminated to obstetric physicians. The law also required that peer review boards at hospitals be established to review cesarean deliveries and that the exact dates of implementation of the guidelines be reported to a state agency. To determine the impact of the legislation, we conducted a retrospective analysis of 366,246 total live births occurring in Florida hospitals during 1992 and 1993, before and after formal hospital certification of the implementation of the guidelines. Changes in primary and repeat cesarean rates were analyzed for 108 independent groups of births, controlling for the mother's age, race, payment source, and the timing of the implementation of the guidelines at hospitals. The guideline certification program did not accelerate the consistent but gradual downward trend in cesarean births which had already been evident in the three prior years. The data do suggest that the guideline program may have affected repeat cesareans more than primary cesareans, especially in the first quarter of 1993, immediately after the hospital certification period. Reductions in repeat cesareans involved both Medicaid and commercially insured births, whereas reductions in primary cesareans were found almost exclusively within commercially insured mothers, where the existing rates are highest. Although births with a prior cesarean represent only 12.5% of all births, significant decreases in repeat cesareans were found in groups representing 72.6% of this population. By comparison, significant decreases in primary cesareans were found in groups representing only 36.5% of the births without a prior cesarean. The date of guideline implementation reported by hospitals was not related to any systematic change in observed cesarean section rates. We concluded that the mere dissemination of practice guidelines by a state agency may not achieve either the magnitude or the specificity of the results desired without an explicit and thorough guideline implementation program. Blunt legislative mandates may be ineffective when multiple initiatives are already achieving desired outcomes.

A national profile of the use of intensive care by Medicare patients with cancer.

BACKGROUND: The broad picture of intensive care unit (ICU) outcomes and expenditures cannot be discerned from previous studies that were conducted at single hospitals and focused on narrow subsets of patients. METHODS: This study provides a comprehensive national profile of ICU used by Medicare patients with cancer. The data source was the Medicare Provider Analysis and Review file for fiscal year 1990, representing 100% of all hospital admissions that occurred within 723 ICD-9-CM codes and organized into 11 code groups. Using screening criteria, admissions were categorized as surgical (both major and minor procedures) or nonsurgical (no procedures) and with and without involvement of the ICU. The categories were compared using the following outcome variables: total hospital charges, ICU charges, ancillary charges, average length of stay, and in-hospital mortality. RESULTS: This study population accounted for nearly 800,000 admissions, of which 143,458 (18.1%) involved the use of the ICU. Actual ICU charges represented 4.9% of the $9.3 billion in total hospital charges. Intensive care unit use is associated positively with service intensity, and 73% of all the admissions involving the ICU were for major procedures. Only 2% involved no procedures. Admissions involving use of the ICU generate higher charges and longer lengths of stay than non-ICU admissions, although the differences decrease with declining treatment intensity and resource use. In-hospital mortality rates, for those cases that used the ICU, were 9.8% for major procedures, 21.2% for minor procedures, and 37.6% for cases involving no procedures. CONCLUSIONS: Contrary to the conclusions drawn from previous research, these findings suggest that patients who receive less intense service and use fewer hospital resources are more likely to die in the hospital than those who receive more care, with or without a stay in the ICU during the hospitalization. A global view of ICU use does not support the conclusion that a disproportionate share of special care resources is expended on futile care of the terminally ill or excessive monitoring of low risk patients, although these problems undoubtedly exist. Analysis of comprehensive national data regarding the use of intensive care provides a perspective that challenges some of the conclusions based on more limited studies that were conducted in single hospitals and focused on nonsurvivors or subsets of patients narrowly defined in other ways.

Response to the National Cancer Institute Alert. The effect of practice guidelines on two hospitals in the same medical community.

BACKGROUND: Despite the recent increase in medical practice guideline development and dissemination, physician compliance with the guidelines has often been low. Previous research has suggested that physicians at hospitals with low volumes of cases and weakened financial status were more likely to omit indicated diagnostic testing or appropriate treatment. The authors sought to determine whether differences in compliance to a widely disseminated set of guidelines would exist even among the most dominant hospital providers within the same medical community. METHODS: Two hospitals, together providing nearly half of the cancer surgery within a metropolitan area, were studied for their compliance to the May 1988 National Cancer Institute (NCI) Clinical Alert regarding adjuvant therapy after primary treatment for node negative breast cancer. A case series consecutive collection of 549 women treated at the study hospitals for 2 years before and two years after the Alert determined those patients who had received any form or combination of adjuvant therapy after primary surgical treatment (lumpectomy or modified radical mastectomy). RESULTS: Following modified radical mastectomy, for women age 50 and older, the university hospital (U) provided adjuvant therapy to a higher percentage of patients than the community hospital (C) both before (25.6% versus 4.7%, P < 0.005) and after (58.9% versus 23.2%, P < 0.001) the Alert. For women younger than 50 years of age, the two hospitals were equally likely to provide adjuvant therapy both before and after the Alert. Following lumpectomy, hospital U increased the percentage of women receiving adjuvant therapy following the Alert in women younger than 50 years of age (25-75.8%, P < 0.001) and in women age 50 and older (33.3-56.5%, P < 0.025). Hospital C provided no adjuvant therapy before or after the Alert. Preferences for breast conserving surgical treatment were significantly (P < 0.001) different with hospital U performing a higher percentage of lumpectomies than hospital C both before (50.9% versus 14.9%) and after (57.6% versus 16.8%) the Alert. CONCLUSIONS: Significant differences in compliance with practice guidelines may be found even among the most dominant hospital providers of cancer services within the same medical community. The role of the surgeon in referring patients to the oncologist greatly influences the ultimate provision of adjuvant therapy. Strategies for enhancing compliance should be considered integral to the process of guideline development.

Intensive care, survival, and expense of treating critically ill cancer patients.

OBJECTIVE: To determine the survival and factors affecting the survival of patients with solid tumors and hematologic cancers who were admitted to the intensive care unit, the time these patients spent at home (meaningful survival) before they died, and the cost per year of life gained and per year of life gained at home. DESIGN: Survival and cost-effectiveness analysis. SETTING: A tertiary-care cancer center at a university medical center. PATIENTS: Every patient admitted to the intensive care unit between July 1, 1988, and June 30, 1990, was entered into the study. This group comprised 83 patients with solid tumors and 64 patients with hematologic cancers. MAIN OUTCOME MEASURES: Factors affecting survival, such as age, sex, malignancy, length of stay in the intensive care unit, and necessity for mechanical ventilator assistance, as well as cost per year of life gained and cost per year of life gained at home. RESULTS: The only factor that significantly affected survival was the requirement for mechanically assisted ventilation for patients with hematologic cancers. More than three fourths of the patients in either group spent less than 3 months at home before dying. The cost per year of life gained for patients with solid tumors was $82,845 and for patients with hematologic cancers was $189,339. The cost per year of life gained at home was $95,142 for patients with solid tumors and $449,544 for patients with hematologic cancers. CONCLUSION: The majority of patients with solid tumors and hematologic cancers admitted to the intensive care unit die before discharge, or, if they survive the hospital admission, they spend a minimal amount of time at home before dying. This limited survival is achieved at considerable cost. Physicians who treat patients with neoplastic disease should discuss potential outcomes and the possibility of withdrawing life-supportive therapy if appropriate with the patient and family, so that a reasonable strategy can be agreed on before the initiation of therapy.

A feedback system for reducing excessive laboratory tests.

At the James A. Haley Veterans Hospital in Tampa, Fla, a program has been implemented to reduce the amount of potentially excessive laboratory testing. The major program components are a set of test frequency guidelines and a system of feedback to resident physicians that compares their test ordering patterns against the predetermined guidelines. The guidelines are analyte specific and differentiate between normal and abnormal test values reported during 1-day and 7-day time periods. The feedback process includes both systematic reporting of objective data and individual and group education and counseling sessions related to the appropriate use of laboratory tests. A reduction in the percentage of tests that fell outside the guidelines (outliers) was achieved following implementation of the program.

The management of hospital medical waste. How to increase efficiency through a medical waste audit.

Medical waste is a nightmare for hospital administrators, cutting across department boundaries and incorporating legal, financial, and community concerns. In this two-part article the author provides a stepwise approach to effective waste management. The first part gives background information on waste generation, storage, and disposal and delineates the framework of a medical waste audit. This audit is put to the test in the second part, where data from a pilot trial at an actual hospital are presented and discussed.

The medical waste audit. A framework for hospitals to appraise options and financial implications.

The generation, handling, and disposal of medical wastes involve virtually every department in the hospital. To enhance coordination, managers must comprehensively describe the total system and specify the roles of key functions and individuals. Hospitals produce about 77 percent of the approximately 500,000 tons of regulated medical waste produced annually in the United States. The amount produced by different hospitals varies, primarily because of differences in "waste-management practices." The Environmental Protection Agency is trying to develop a greater understanding of the types of medical wastes that are infectious, methods of transmission, and the likelihood of transmission in the handling and disposal of waste within the hospital environment. To ensure that medical waste is being handled and treated in the most cost-effective manner and with the least health risk to employees and the community, hospital administrators must undertake a comprehensive appraisal of the activities associated with the generation, handling, and disposal processes. A "medical waste audit" requires the following steps: Generation profile to identify origination points, categories or types of waste, and associated generation rates. Inventory of handling practices, including existing regulations, procedures and protocols, training programs, definitions regarding waste segregation, and documentation. Review of current disposal practices and existing and developing alternatives. Cost analysis

Cybernetic appropriateness review. Does it change physician hospital utilization patterns?

All hospital care can be characterized as either appropriate (i.e., efficatious and necessary) or inappropriate (i.e., services without benefit or services that could be provided in a less costly setting). A demonstration project combining an appropriateness determination methodology with a cybernetic control system was implemented in a study area that included six hospitals and approximately 400 practicing physicians. Project results to date indicate substantial improvements in the ratio of appropriate to inappropriate care for both hospitals and individual physicians. Evaluation research design problems and areas of future research are also discussed.

Impact of a cybernetic system of feedback to physicians on inappropriate hospital use.

A cybernetic control program aimed at reducing inappropriate days of hospital stay for patients was implemented for all Medicare admissions at hospitals in four counties in Western Maryland. The findings of a study of the program are reported here. The objective of the study was to determine the relationship of the volume of the physician's hospitalized patients on both the existing levels of inappropriate hospital utilization and the physician's response to the cybernetic system. The findings indicated that: (a) existing levels of inappropriate hospital use generally increased with higher patient volume, (b) physicians with a low volume of hospitalized patients were less likely to decrease their inappropriate use of hospitals as a result of feedback than physicians with medium or high volumes of admitted patients, and (c) at all volume levels, the average decrease in inappropriate days was larger than the average increase in inappropriate days.
