Clinical service standards at academic health centers.

OBJECTIVE: To describe the content and variability for clinical service standards related to quality of care among a convenience sample of academic health centers. DESIGN: We used the membership of the University HealthSystem Consortium, an alliance of academic health centers in the United States for clinical services, to survey electronically 53 of these centers regarding clinical service standards. The survey evaluated service standards in four areas; general communications, communications between physicians, ambulatory and inpatient clinical services and administrative standards. RESULTS: Thirty-four institutions responded to the survey (64%). Of these, 16 (47%) had clinical service standards, while the remaining 18 (53%) had not established formal standards. A few of the centers had established standards for patient communications, such as policies for answering telephones by staff. More had developed standards for communications between physicians and most centers had established standards for appointment availability, especially for urgent visits. However, clinical service standards were less typical for inpatient consultative or diagnostic services. A small number of the academic health centers had standards for hours of operation and for handling administrative matters, such as patient complaints. For many clinical service standards at the centers, there were notable variations (e.g. non-urgent primary care visits ranged 3-14 days). CONCLUSION: Some academic health centers have developed and implemented patient-centered clinical service standards for diverse areas of practice, however, the standards used appear to vary for some aspects of care, but not for others.

Marketplace reforms and primary care career decisions.

A dramatic shift in the postgraduate career choices of medical school graduates toward primary care occurred during the mid-1990s. While some attributed this shift to changes in medical school curricula, perceptions stemming from marketplace reforms were probably responsible. For the most part, these perceptions were probably generated through informal communications among medical students and through the media. More recently, additional marketplace influences, such as the consumer backlash toward managed care and unrealized gains in primary care physicians' personal incomes, may have fostered contrasting perceptions among medical students, leading to career choices away from primary care, particularly family practice. The authors offer two recommendations for enhancing the knowledge of medical students concerning workforce supply and career opportunities: an educational seminar in the second or third year of medical school, and a public-private partnership between the Bureau of Health Professions and the Association of American Medical Colleges to create a national database about the shape of the primary care and specialty workforces, accessible through the Internet for educators, students, and policymakers. The authors conclude that appropriate career counseling through these efficient methods could avoid future abrupt swings in specialty choices of medical school graduates and may facilitate a more predictable physician workforce supply.

Three strategies used by academic health centers to expand primary care capacity.

The growth of managed care in the late 1980s and early 1990s severely disadvantaged academic health centers (AHCs). The reliance on primary care gatekeeping and selective contracting by managed care plans were two contributing factors. Because most AHCs had only a modest primary care capacity, they were understandably concerned about their strategic positions. Thus, many felt it was essential to expand their primary care capacities to ensure downstream referrals, to improve contract negotiations with third parties, and to permit assumption of risk for defined populations. Among the different approaches used, three principal strategies emerged for the expansion of the primary care capacity of AHCs: (1) the "assembly strategy," in which many AHCs recruited new generalist faculty into existing clinical departments; (2) the "acquisition strategy," in which AHCs purchased established primary care practices in the community; and (3) the "affiliation strategy," in which some AHCs affiliated with primary care physicians in the community and formed networks of academic and community physicians. For each of these approaches, the author reviews the relative merits and disadvantages, and analyzes why some AHCs' original assumptions about the imperative for increasing primary care capacity may have been spurious. He concludes that recent marketplace and regulatory changes may make it less necessary for AHCs to secure substantial primary care bases in the future.

Electronic medical record systems at academic health centers: advantages and implementation issues.

The growth of managed care has fueled expectations for a more coordinated delivery of clinical services and a reduction of unnecessary utilization. Among the most important issues that constrain these expectations is the transfer of medical information. Electronic medical record (EMR) systems appear to offer substantive advantages over paper records for both containing costs and improving the quality of care. However, incorporation of EMR systems into practice settings has languished. Among the barriers to implementation are software problems of codification and entry of data, security issues, a dearth of integrated delivery systems, reluctant providers, and prohibitive costs. The training programs of academic health centers (AHCs) are optimal environments for testing and implementing EMR systems. AHCs have the expertise to resolve remaining software issues, the components necessary for integrated delivery, a culture for innovation in clinical practice, and a generation of future providers that can be acclimated to the requisites for computerized records. The authors critically review these and other issues of implementing EMR systems at AHCs and propose four necessary steps for financing their implementation.

A sociodemographic and economic comparison of breast reconstruction, mastectomy, and conservative surgery.

BACKGROUND: There are a variety of surgical choices for women with early-stage breast cancer, including breast-conserving surgery, mastectomy, or mastectomy plus reconstructive surgery. This report examines some of the factors that affect these choices and the costs of the various treatment options. METHODS: Data from the Virginia Cancer Registry were linked to insurance claims from the Trigon Blue Cross and Blue Shield Company for women with local and regional staged breast cancer from 1989 to 1991 in Virginia. Multivariate analyses and cost studies were performed. RESULTS: There were 592 women who underwent breast-conserving surgery (BCS, 26%), mastectomy (58%), or mastectomy plus reconstruction (16%). Increasing age reduced the use of reconstruction. The choice of reconstruction was not affected by tumor size, nodal status, or race. Sixty percent of women had immediate breast reconstruction at the time of mastectomy; the majority had the implant procedure. The cost of BCS ($21,582) was higher than that of mastectomy ($16,122, P < .01). The costs for BCS and mastectomy were significantly lower than for mastectomy plus reconstruction ($31,047, P < .05). The 2-year cost for immediate reconstruction was $8200 less than for delayed procedures and was similar to the cost of BCS. CONCLUSIONS: Age was the driving force in reconstruction decisions. Clinical factors such as tumor size and nodal status were more important for the choice between BCS and mastectomy. There are significant cost differences between the various procedures. For a similar cosmetic outcome, BCS is less expensive than breast reconstruction. When reconstruction is required, a simultaneous procedure is less expensive.

Predictors of Medicare costs in elderly beneficiaries with breast, colorectal, lung, or prostate cancer.

BACKGROUND: Determining the apportionment of costs of cancer care and identifying factors that predict costs are important for planning ethical resource allocation for cancer care, especially in markets where managed care has grown. DESIGN: This study linked tumor registry data with Medicare administrative claims to determine the costs of care for breast, colorectal, lung and prostate cancers during the initial year subsequent to diagnosis, and to develop models to identify factors predicting costs. SUBJECTS: Patients with a diagnosis of breast (n = 1,952), colorectal (n = 2,563), lung (n = 3,331) or prostate cancer (n = 3,179) diagnosed from 1985 through 1988. RESULTS: The average costs during the initial treatment period were $12,141 (s.d. = $10,434) for breast cancer, $24,910 (s.d. = $14,870) for colorectal cancer, $21,351 (s.d. = $14,813) for lung cancer, and $14,361 (s.d. = $11,216) for prostate cancer. Using least squares regression analysis, factors significantly associated with cost included comorbidity, hospital length of stay, type of therapy, and ZIP level income for all four cancer sites. Access to health care resources was variably associated with costs of care. Total R2 ranged from 38% (prostate) to 49% (breast). The prediction error for the regression models ranged from < 1% to 4%, by cancer site. CONCLUSIONS: Linking administrative claims with state tumor registry data can accurately predict costs of cancer care during the first year subsequent to diagnosis for cancer patients. Regression models using both data sources may be useful to health plans and providers and in determining appropriate prospective reimbursement for cancer, particularly with increasing HMO penetration and decreased ability to capture complete and accurate utilization and cost data on this population.

Factors associated with changes in satisfaction with care.

OBJECTIVE: Satisfaction with care is an important outcome for evaluating the effectiveness of medical care. Many factors can influence satisfaction, including disease state, healthcare utilization, and health-status changes. However, few studies have investigated the association between these factors and changes in satisfaction. DESIGN: This study examined the influence of personal characteristics, type of health plan, disease states, and healthcare utilization on changes in satisfaction with care in a prospective cohort over a 12-month period through two surveys, baseline and follow-up. PARTICIPANTS: Enrollees in one of three different commercial health plans: point-of-service product, an unrestricted fee-for-service product, and a preferred-provider organization product. MEASUREMENTS AND MAIN RESULTS: Two multivariate logistic regression models were constructed. The first model evaluated factors that predicted increased satisfaction with care between the two surveys. Compared with respondents who reported no change in health status, both those with improved health status (odds ratio [OR], 1.29, 95% confidence interval [CI95], 1.03-1.61) and those with declines in health (OR, 1.29, CI95, 1.03-1.61) were significantly more likely to report an increase in satisfaction with care. Those with a history of hospitalization were also more likely to report an increase in satisfaction with care (OR, 1.27, CI95, 1.01-1.59). The second multivariate logit model evaluated factors that predicted decreases in satisfaction with care from the baseline survey. Those with reported declines in health status were more likely to report decreases in satisfaction with medical care (OR, 1.43, CI95, 1.13-1.79). Neither age, gender, race, type of health plan, disease state, nor doctor's office visits were related to observed changes in satisfaction with medical care. CONCLUSION: Changes in satisfaction with care appear to be related to changes in health status. However, the relation between these two attributes is not intuitively apparent.

A comparison of patterns of care of nonsmall cell lung carcinoma patients in a younger and Medigap commercially insured cohort.

BACKGROUND: The objective of this study was to examine and compare lifetime treatment patterns and hospitalization of incident nonsmall cell lung carcinoma (NSCLC) between pre-Medicare eligible (age < 65 years) and supplemental Medigap (age > or = 65 years) enrollees in a commercially insured cohort using insurance claims. METHODS: Claims from Virginia Blue Cross and Blue Shield beneficiaries with NSCLC submitted between 1989-1991 were merged with records from the Virginia Cancer Registry (VCR). Data from the VCR identified incident cases, disease stage, and type of tumor. Initial treatment categories were stratified using Physicians' Current Procedural Terminology codes. RESULTS: There were 1706 incident NSCLC patients; 349 were age < or = 64 years ("younger") and 1212 were age > or = 65 years ("elderly"). Having commercial insurance was not associated with any survival advantage compared with national averages at 2 years. In comparison with elderly patients, younger patients more often were treated with surgery for local disease (80.2% vs. 54.8%) and surgery alone or in combination with radiation for regional disease (51.9% vs. 32.0%). Radiation was used more often in elderly patients compared with younger patients with local disease (30.5% vs. 14.0%) but less often in patients with distant disease (76.2% vs. 54.9%). Compared with elderly patients, younger patients presenting with distant disease received more chemotherapy (18.8% vs. 5.1%; P <0.001); late palliative use of chemotherapy or radiation occurred in only 4-8% of younger patients. Compared with elderly patients, younger patients with regional or distant disease spent more days in the hospital (compared with national averages at 2 years: regional disease, 30.0 vs. 23.9 days; distant disease, 33.0 vs. 21.4 days; P <0.0001). CONCLUSIONS: The results of this study show that more comprehensive health insurance is not associated with better outcomes in patients with NSCLC. Age specific trends for greater use of surgery, radiation, and total hospitalization in younger patients is consistent with other reports. Commercial health care claims supplemented by clinical staging from cancer registries can address long term practice patterns in patients with cancer.

Costs of care associated with non-small-cell lung cancer in a commercially insured cohort.

PURPOSE: To examine the cost of incident cases of non-small-cell lung cancer (NSCLC) in a commercially insured cohort. METHODS: Claims from Virginia Blue Cross and Blue Shield (BCBS) beneficiaries with lung cancer from 1989 to 1991 were merged with records from the Virginia Cancer Registry (VCR). Data from the VCR identified incident cases, stage, and type of cancer at diagnosis. Costs for all medical care included insurance payment, copayments, and deductibles for 2 years after diagnosis or until death. RESULTS: Three hundred forty-nine incident NSCLC patients were evaluated. The mean 2-year cost for each patient after diagnosis or until death was $47,941 (95% confidence interval, $43,758 to $52,124). Total average costs and hospital days were significantly lower for local disease ($37,514, 21.2 days), but were similar for regional ($52,797, 30.0 days) and distant ($49,382, 33.0 days) disease. Hospital days accounted for 48% and hospital-based claims for 70% of costs. Initial treatments, which included radiation, unadjusted for stage, had the lowest survival rates and the highest costs, and were associated with the most hospital days. Initial stage, race, gender, and age were not predictors of total 2-year costs. The independent predictors of total 2-year costs were type of treatment: any radiation therapy, any surgery, or any chemotherapy (all, P < .001). Inpatient hospital days was only a modest predictor of costs after adjusting for type of treatment. Patients who survived less than 1 year spent 30.5 days in hospital and had an average cost of $47,280. CONCLUSION: The direct health care costs of younger NSCLC patients care are substantial. These results should serve as a benchmark for future comparisons as the United States market shifts to managed care.

Adverse selection at academic health centers.

Market influences are placing many academic health centers (AHCs) in financial distress. Competitive forces threaten the core missions of AHCs, principally because of selective contracting, which has introduced price competition to medical care. This manuscript discusses the issue of adverse selection for AHCs, the probability that patients with higher levels of illness severity seek care at, or are referred to, AHCs. AHCs are particularly vulnerable to adverse selection because of their prominence as referral centers, their specialty composition, research expertise, and the socioeconomic status of patients located proximal to their centers. The adverse selection of AHCs increases the likelihood that health plans will trim their networks to exclude them. Health plans may still contract with AHCs for tertiary care only, but this will only worsen the adverse selection at AHCs.

Perioperative management of colon cancer under Medicare risk programs.

OBJECTIVE: To determine differences in perioperative care and outcomes for patients with colon cancer enrolled in Medicare health maintenance organizations compared with similar fee-for-service nonenrollees. METHODS: Cross-sectional evaluation of hospital care and posthospital outcomes with data obtained from medical records. Nineteen health maintenance organizations representing all model types were selected from 12 states. The nonenrollee sample was drawn from the same areas. The sample included 412 enrollees and 401 nonenrollees, representing 65 hospitals for health maintenance organizations and 61 hospitals for fee-for-service. RESULTS: Nonenrollees were slightly older and had higher preoperative risk. Enrollees had shorter intervals between admission and surgery (enrollees, 1.55 days vs nonenrollees, 2.85 days). Differences in length of stay (enrollees, 10.9 days vs nonenrollees, 14.2 days) persisted even after controlling for preoperative health status. Differences in admissions to intensive care units (enrollees, 36.4% vs nonenrollees, 44.4%) were highly influenced by preoperative health status. Nonenrollees were more significantly likely to receive preoperative antibiotics, postoperative testing (eg, postoperative chest radiographs and electrocardiograms), and postoperative patient-controlled analgesia. Tumor staging was similar for both groups. Enrollees were more likely to be discharged home, while nonenrollees were more likely to be discharged to a nursing home. There were no significant differences in hospital deaths or postdischarge readmissions. CONCLUSIONS: Health maintenance organization enrollees with colon cancer received less clinical services of several types than similar patients in fee-for-service settings, had shorter hospital stays, and were less likely to be discharged to nursing homes. However, there was no evidence that they experienced different outcomes.

The modification of physician practice patterns.

While physicians are directly responsible for only a small proportion of healthcare expenditures, their decisions influence the majority of medical costs. Because practice variations among physicians have been demonstrated abundantly, strategies to modify practice patterns have evolved. This article addresses the different factors that influence variations in patterns of practice, including physician characteristics, knowledge, beliefs, and attitudes. In designing programs to modify practice patterns, educational efforts, along with practice guidelines and feedback, all have been used. Although there are mixed results for each, the use of opinion leaders and the timing of interventions proximal to practice decisions are important. The costs and benefits of interventions are discussed as a method for assessing the utility of different programs to modify practice patterns.

Outcomes of stroke patients in Medicare fee for service and managed care.

CONTEXT: Increasing numbers of Medicare beneficiaries have been enrolling in health maintenance organizations (HMOs) because HMO participation reduces out-of-pocket expenses, and the federal government views HMOs as a way to contain Medicare costs. However, results comparing outcomes and quality of care in HMOs vs fee for service (FFS) have been mixed, and outcomes after stroke have not been adequately assessed. OBJECTIVE: To compare discharge destinations and survival rates following stroke in Medicare HMOs with similar FFS settings. DESIGN: An observational study for 2 groups evaluating stroke patients' discharge destinations and survival times from the date of hospital admission. SETTING: A total of 19 HMOs were selected from 12 states. The FFS sample was drawn from the same geographic areas. PATIENTS: The sample included 402 HMO patients from 71 hospitals and 408 FFS patients from 60 hospitals. PROCESS AND OUTCOME MEASURES: Data were abstracted from medical records on demographics, clinical characteristics of stroke, comorbid illnesses, and discharge destinations following hospitalization. Data on survival were obtained from Medicare files and included 25 to 37 months of follow-up (median, 30.4 months, HMO; 31.1 months, FFS) from the date of hospital admission. RESULTS: There were 109 patients who died during the hospitalization (49 HMO, 12.2%; 60 FFS, 14.7%), and a total of 410 patients had died by the end of follow-up (191 HMO, 47.5%; 219 FFS, 53.7%). Approximately one fourth of both groups had do-not-resuscitate orders (HMO, 25.4%; FFS, 27.9%; P=.68). After controlling for age, marital status, and characteristics of dependency at discharge, HMO patients were more likely than FFS patients to be sent to nursing homes (HMO, 41.8%; FFS, 27.9%; P=.001) and less likely to be discharged to rehabilitation hospitals or units (HMO, 16.2%; FFS, 23.4%; P=.03). At follow-up, no significant differences in relative risk of dying were found between HMO and FFS groups (relative risk, 0.96; 95% confidence interval, 0.73-1.26; P=.77). CONCLUSIONS: Patients in Medicare HMOs who experience strokes are more likely to be discharged to nursing homes and less likely to go to rehabilitation facilities following the acute event. However, they have similar survival patterns compared with comparable patients in FFS settings after adjusting for other factors.

Establishing physician networks within evolving antitrust guidelines.

Rapid changes in health care are being driven by the growth of managed care. Health plans have become more aggressive in negotiating with physicians, and providers have increasingly chosen to establish networks in response. Because these provider networks frequently represent horizontal forms of integration between competitors, antitrust issues have become increasingly important. This article addresses current antitrust law as it relates to physician networks. In particular, it reviews the most recent statements of antitrust enforcement policy of the Department of Justice and the Federal Trade Commission concerning physician networks. Procompetitive activities by physician networks are central to the latest rulings.

Measuring standards of care for early breast cancer in an insured population.

PURPOSE: To demonstrate the use of a combined data base to evaluate the care for local/regional invasive breast cancer in a large insured population of women aged less than 64 years. PATIENTS AND METHODS: We linked the procedural and hospital claims from Blue Cross Blue Shield (BCBS) of Virginia with clinical stage data from the Virginia Cancer Registry (VCR) from 1989 to 1991. A total of 918 women were assessed with a median age of 50 years; 68% had tumors less than 2 cm, 30% had positive axillary nodes, and 68% were assessed as having local summary stage. A quality-of-care "report card" was used based on standards of care from international Consensus Conferences. RESULTS: Eight percent had a mastectomy as the initial biopsy procedure. Sixty-nine percent of women ultimately underwent mastectomy. Of those women who underwent lumpectomy, 86% had subsequent radiation. Within 3 months of diagnosis, 43% had a bone scan and 20% a computed tomography (CT) scan. Of women with positive axillary lymph nodes, 83% aged less than 51 years and 52% aged 51 to 64 years received chemotherapy. Fifty-six percent of all women had claims from a medical oncologist. Of women having a total mastectomy, 27% had claims from a plastic surgeon. Sixty-six percent to 76% of women had a mammogram, 24% a bone scan, and 14% a CT scan in the 0-18 and 18-36 month intervals following primary treatment. CONCLUSION: This study confirms the feasibility of linking sources of data that provide complementary information needed to develop measurements regarding standards of quality and efficiency of oncologic care. This report should serve as an initial benchmark while we await reports from other populations to define the best practice.

Ability of Medicare claims data and cancer registries to identify cancer cases and treatment.

The objective of this study is to compare the ability of Medicare and cancer registry data to identify incident cancer cases and initial surgical therapy both singly and in combination. Data from the Virginia Cancer Registry (VCR) were linked to Medicare claims files (Medical Provider Analysis and Review File (MEDPAR)) for Virginia residents aged 65 years and over with breast, colorectal, lung, or prostate cancer diagnosed between 1986 and 1989. MEDPAR found 73-83% of cancer cases identified by VCR. Factors significantly associated with MEDPAR missing a case that was reported to VCR included younger age, male gender, living in an urban area, higher social class, in situ disease, and lack of cancer treatment. A total of 70-82% of cancer cases identified through Medicare claims were reported to the VCR. Older age, female gender, nonwhite race, comorbid conditions, no surgical procedures, multiple cancer admissions, and the position of the cancer diagnostic code on the MEDPAR record were factors significantly related to being missed by the VCR. The rate of capturing initial surgical therapies was similar to that of identifying cases. Combining information from VCR and MEDPAR resulted in increasing sensitivity for identifying incident cases to 92-97%. Using combined data from independent sources may improve reporting, increase the accuracy of cancer incidence estimates, and provide an opportunity to identify reasons for missing data.

Marketplace challenges and opportunities for faculty practice plans.

Because of marketplace challenges related to the growth of managed care, faculty practice plans (FPPs) now are faced with issues similar to community group practices. Emphasis on primary care and price discounts are particularly thorny concerns. Unreimbursed care looms as a hazards for the FPPs affiliated with teaching hospitals in low socioeconomic areas. However, as the marketplace cultivates more global pricing strategies, the FPP-hospital relationship also could prove a distinct advantage. Additionally, the recent emergence of practice management corporations could represent opportunities for FPPs, who need new competencies, and even capital, to remain competitive. This article also discusses the promise of integrated delivery networks and addresses the construction of community partnerships.
