Racial disparities negatively impact outcomes in early-onset colorectal cancer independent of socioeconomic status. Cancer Med 2021; 10:7542-7550. [PMID: 34647438 PMCID: PMC8559495 DOI: 10.1002/cam4.4276] [Citation(s) in RCA: 21] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2021] [Revised: 08/18/2021] [Accepted: 08/24/2021] [Indexed: 12/25/2022] Open
Abstract
BACKGROUND The incidence of colorectal cancer (CRC) in patients under age 50 is rising for unclear reasons. We examined the effects of socioeconomic factors on outcomes for patients with early-onset CRC compared to late-onset CRC. METHODS Patients with CRC from 2004 to 2015 in the National Cancer Database were included and categorized by age (under or over 50 years). Differences in demographic and socioeconomic factors, disease characteristics, and survival outcomes between early-onset versus late-onset CRC patients were assessed by Chi-squared test and Cox models. RESULTS The study population included 1,061,204 patients, 108,058 (10.2%) of whom were under age 50. The proportion of patients diagnosed under age 50 increased over time: 9.4% in 2004-2006, 10.1% in 2007-2009, 10.5% in 2010-2012, and 10.7% in 2013-2015 (p < 0.0001). Early-onset CRC patients were more likely to be Black (15.1% vs. 11.3%) or Hispanic (8.6% vs. 4.6%) and to present with stage 4 disease (24.9% vs. 17.0%), p < 0.0001 for all. Black patients had the worst median OS (58.3 months) compared to White (67.0 months), Hispanic (91.6 months), or Asian (104.9 months) patients, p < 0.0001. Within the subgroup of early-onset CRC patients with private insurance, Black patients had worse OS compared to White patients, even in communities with higher income and education status. CONCLUSIONS Early-onset CRC continues to increase. Patients with early-onset CRC are more likely to be Black or Hispanic and to present with stage 4 cancer. Early-onset Black patients showed worse OS compared to White patients in all income subgroups, even with private insurance.

Abstract
PURPOSE Practice guidelines recommend that patients who receive neoadjuvant chemotherapy and radiation for locally advanced rectal cancer complete postoperative adjuvant systemic chemotherapy, irrespective of tumor downstaging. PATIENTS AND METHODS The National Comprehensive Cancer Network (NCCN) Colorectal Cancer Database tracks longitudinal care for patients treated at eight specialty cancer centers across the United States and was used to evaluate how frequently patients with rectal cancer who were treated with neoadjuvant chemotherapy also received postoperative systemic chemotherapy. Patient and tumor characteristics were examined in a multivariable logistic regression model. RESULTS Between September 2005 and December 2010, 2,073 patients with stage II/III rectal cancer were enrolled in the database. Of these, 1,193 patients receiving neoadjuvant chemoradiotherapy were in the analysis, including 203 patients not receiving any adjuvant chemotherapy. For those seen by a medical oncologist, the most frequent reason chemotherapy was not recommended was comorbid illness (25 of 50, 50%); the most frequent reason chemotherapy was not received even though it was recommended or discussed was patient refusal (54 of 74, 73%). After controlling for NCCN Cancer Center and clinical TNM stage in a multivariable logistic model, factors significantly associated with not receiving adjuvant chemotherapy were age, Eastern Cooperative Oncology Group performance status ≥ 1, on Medicaid or indigent compared with private insurance, complete pathologic response, presence of re-operation/wound infection, and no closure of ileostomy/colostomy. CONCLUSION Even at specialty cancer centers, a sizeable minority of patients with rectal cancer treated with curative-intent neoadjuvant chemoradiotherapy do not complete postoperative chemotherapy. Strategies to facilitate the ability to complete this third and final component of curative intent treatment are necessary.

Abstract
Economists have generated a large body of theoretical and empirical knowledge with respect to the design of physician remuneration methods (PRM). This knowledge is difficult to use for a policy maker, because of its technical nature and its fragmentation. The article brings together the scattered elements of theory and evidence into a structured framework that adds practical use value to economic theory, useful in the applied practice of policy development, design, implementation, and evaluation. The article argues that the optimal choice of PRM depends on the goals of the health care system, and on external contextual factors. Fee-for-service payments are best when the goals are quantity of care and risk acceptance. Capitation is best when the goals are collaboration between providers and delivery of preventive services and health promotion. Salaries are best when population density is low, and the goal is to recruit physicians to rural and remote areas. Blended payment models are recommended for the achievement of multiple goals. As a demonstration of use value, the framework is applied to the assessment of Canadian PRM.

Abstract
BACKGROUND The purpose of the present paper was to examine patterns of surgical care and the likelihood of death within 5 years after a diagnosis of colorectal cancer, including the effects of demographic, locational and socioeconomic disadvantage and the possession of private health insurance. METHODS The Western Australian Data Linkage System was used to extract all hospital morbidity, cancer and death records for people with a diagnosis of colorectal cancer from 1982 to 2001. Demographic, hospital and private health insurance information was available for all years and measures of socioeconomic and locational disadvantage from 1991. A logistic regression model estimated the probability of receiving colorectal surgery. A Cox regression model estimated the likelihood of death from any cause within 5 years of diagnosis. RESULTS People were more likely to undergo colorectal surgery if they were younger, had less comorbidity and were married/defacto or divorced. People with a first admission to a private hospital (odds ratio (OR) 1.31, 95% confidence interval (CI): 1.16-1.48) or with private health insurance (OR 1.27, 95% CI: 1.14-1.42) were more likely to undergo surgery. Living in a rural or remote area made little difference, but a first admission to a rural hospital reduced the likelihood of surgery (OR 0.76, 95% CI: 0.66-0.87). Residency in lower socioeconomic areas also made no difference to the likelihood of having surgical treatment. The likelihood of death from any cause was lower in those who were younger, had less comorbidity, were elective admissions and underwent surgery. Residency in lower socioeconomic status and rural areas, admission to a rural hospital or a private hospital and possession of private health insurance had no effect on the likelihood of death. CONCLUSIONS The present study demonstrates that socioeconomic and locational status and access to private health care had no significant effects on surgical patterns of care in people with colorectal cancer. However, despite the higher rates of surgery in the private hospitals and among those with private health insurance, their survival was no better.

Abstract
BACKGROUND Colorectal cancer is relatively frequent among adults of working age, yet few studies have examined treatment, outcomes, and costs for people under 65 years of age with this disease. OBJECTIVE The objective of this study was to compare the initial treatments, survival, cancer-related medical costs, and overall medical costs for working-aged persons with colorectal cancer in 2 large health insurance plans in Washington State, one a preferred provider organization (PPO) and the other a group model health maintenance organization (HMO). STUDY POPULATION This study consisted of patients, aged 20-64 years, diagnosed with colorectal cancer in both health plans from 1996 to 1998. For each cancer case, up to 5 control subjects, matched on age and sex, were selected for the analysis. METHODS We calculated unadjusted, attributable, and overall medical costs using the Kaplan-Meier sample average estimator. We calculated relative mortality rates using Cox regression. We used propensity scores to adjust overall costs and survival for potential confounding factors. RESULTS Two hundred ten persons in the PPO and 136 persons in the HMO, aged 20-64 years, were diagnosed with cancer over the observation period and included in this study. Patients in the PPO were more likely to have local excision of their tumor (16% compared with 11%) and were less likely to receive chemotherapy (48% compared with 60%). The overall medical costs for the cancer cases were $46,000 in the HMO and $46,400 in the PPO (95% confidence interval for the difference: -$19,300 to 20,100). The cancer-attributable medical costs over 2 years were $40,400 in the HMO and $44,300 in the PPO (95% confidence interval for the difference: -$17,400 to 25,200). Survival was similar in the 2 health plans: the hazard ratio was 0.89 for those enrolled in the PPO (95% confidence interval: 0.50 to 1.59). Adjustment for potential confounding factors altered the results little. CONCLUSIONS There were differences in the initial treatment of the patients in each health plan, but costs and survival were not significantly different between the 2 plans.

Abstract
BACKGROUND Nonmedical costs of care, such as patient time associated with travel to, waiting for, and seeking medical care, are rarely measured systematically with population-based data. OBJECTIVES The purpose of this study was to estimate patient time costs associated with colorectal cancer care. METHODS We identified categories of key medical services for colorectal cancer care and then estimated patient time associated with each service category using data from national surveys. To estimate average service frequencies for each service category, we used a nested case control design and SEER-Medicare data. Estimates were calculated by phase of care for cases and controls, using data from 1995 to 1998. Average service frequencies were then combined with estimates of patient time for each category of service, and the value of patient time assigned. Net patient time costs were calculated for each service category, summarized by phase of care, and compared with previously reported net direct costs of colorectal cancer care. RESULTS Net patient time costs for the 3 phases of colorectal cancer care averaged dollar 4592 (95% confidence interval [CI] dollar 4427-4757) over the 12 months of the initial phase, dollar 2788 (95% CI dollar 2614-2963) over the 12 months of the terminal phase, and dollar 25 (95% CI: dollar 23-26) per month in the continuing phase of care. Hospitalizations accounted for more than two thirds of these estimates. Patient time costs were 19.3% of direct medical costs in the initial phase, 15.8% in the continuing phase, and 36.8% in the terminal phase of care. CONCLUSIONS Patient time costs are an important component of the costs of colorectal cancer care. Application of this method to other tumor sites and inclusion of other components of the costs of medical care will be important in delineating the economic burden of cancer in the United States.

Abstract
BACKGROUND Colorectal cancer is the second leading cause of cancer deaths in the United States each year. Screening is effective in reducing colorectal cancer mortality; however, compliance with screening is poor, and factors associated with its compliance are poorly understood. The outcomes of treatment of colorectal cancer (surgery, radiation therapy, and chemotherapy) may have profound effects on quality of life (QOL). Furthermore, colorectal cancer screening and treatment may be expensive, and the costs are important from a policy perspective. This review examines patient-centered outcomes research related to colorectal cancer screening and treatment and outlines the work that has been done in several areas, including patient preferences, QOL, and economic analysis. METHODS The literature on the health outcomes associated with colorectal cancer screening and treatment was reviewed. A MEDLINE search of English language articles published from January 1, 1990 through February 2001, was conducted and was supplemented by a review of references of obtained articles. Criteria for study inclusion were identified a priori. A standardized data abstraction form was developed. Summary statistical analyses were performed on the results. RESULTS Six hundred eighty-six articles were selected for review. In total, 530 articles were excluded because they either did not include patient-centered outcomes, were duplicate articles, or could not be obtained. There were 156 articles included in the analysis; 67 addressed screening, 18 examined surveillance of high-risk groups, 22 concerned treatment of local disease, 10 examined treatment of local and metastatic disease, and 19 considered treatment of metastatic disease only. One study examined end-of-life care. In 19 studies, the phase of care was unspecified. CONCLUSIONS Standardized, disease-specific QOL instruments should be applied in clinical trials so that the results may be compared across different types of interventions. Valid and reliable methods that accurately capture patient preferences regarding screening and treatment should be developed.

Abstract
STUDY OBJECTIVES To compare kinds and amounts of health care used by adults with asthma in managed care and fee-for-service settings. DESIGN Cross-sectional structured telephone survey of Northern California adults with asthma from random samples of pulmonologists, allergist-immunologists, family practitioners, and from a random sample of the non-institutionalized population. MEASUREMENTS Validated measures of kind of health insurance plans, kinds and amounts of services used for asthma and other reasons, demographic characteristics, severity of asthma, comorbidity, and overall health and functional status. RESULTS Eighty one percent of the 416 adults with asthma studied were in some form of managed care (75% in HMOs and 6% in PPOs). Those in managed care (MC) and fee-for-service (FFS) did not differ substantively in the proportion with a regular source or principal provider of asthma care, with a peak flow meter or action plan, having received instructions in the use of an inhaler, reporting current use of inhaled beta-agonists, home nebulized beta-agonists, or inhaled steroids, or reporting ER visits or flu shots in the year prior to interview. Persons with asthma in MC reported significantly fewer total physician visits (after adjustment, 4.3 MC, 7.1 FFS, difference = 2.8, 95% CI -5.4, -0.1), principally because those in MC had many fewer visits to allergist-immunologists (after adjustment 4.9 MC, 21.4 FFS, difference = -16.5, 95% CI -27.8, -5.3). The two groups did not differ significantly in the proportion with asthma-related or nonasthma hospital admissions. CONCLUSIONS Persons with asthma in fee-for-service settings reported a greater number of certain kinds of ambulatory visits, particularly visits to allergist-immunologists, for their asthma than those in managed care, but did not differ in the use of the hospital for their asthma and in nonasthma care.

Abstract
BACKGROUND The current study examined the relationship between socioeconomic and demographic factors and type of treatment for carcinomas of the colon and rectum. The National Institutes of Health and the National Cancer Institute recommend surgery followed by adjuvant chemo- and/or radiotherapy for Stage III colon and Stages II and III rectal carcinomas. METHODS The authors linked Washington State's cancer registry and hospital discharge records and U.S. census data to assess socioeconomic and demographic factors related to treatment, controlling for clinical factors. RESULTS Compared to colon carcinoma patients under age 65 years, patients aged 75-84 years and 85 years or older were at higher risk for a treatment plan of surgery without adjuvant therapy (adjusted odds ratio [OR] = 2.5, 95% confidence interval [CI] = 1.3-4.7; OR = 14.1, CI = 6.3-31.4, respectively). Risk of no adjuvant therapy was more than doubled for patients in zip codes in the lowest quartile of per capita income compared to the top three quartiles (OR = 2.3, CI = 1.5-3.4) and for those with Medicare compared to private insurance (OR = 2.2, CI = 1.3-3.8). Older patients with rectal carcinoma were also at higher risk of a treatment plan that did not include adjuvant therapy. CONCLUSIONS The current findings suggest disparities in the provision of recommended medical procedures related to socioeconomic and demographic factors.

Abstract
The objective of a treatment outcome study is to investigate the heterogeneity in outcome between patients according to factors other than treatment, such as country, institution or physician. Results of treatment outcome studies have already been extensively presented in the medical literature. However, no clear methodology has emerged to perform treatment outcome studies and various methods have been used. This paper reviews the different types of questions addressed in treatment outcome studies, the different methodologies and the different endpoints used. Statistical techniques are mainly descriptive including tables, estimates of survival curves, but regression models have also been used. Most of the studies use registry data, while only a few use discharge data or data available from clinical trials.

Abstract
BACKGROUND Our aim was to compare access to effective care among elderly Medicare patients in a Staff Model and Group Model HMO and in Fee-for-Service (FFS) care. METHODS We used a retrospective cohort study design, using claims and automated medical record data to compare achievement on quality indicators for elderly Medicare recipients. Secondary data were collected from 1) HMO data sets and 2) Medicare claims files for the time period 1994-95. All subjects were Medicare enrollees in a defined area of New England: those enrolled in two divisions of a managed care plan with different physician payment arrangements: a staff model, and a group model; and the Medicare FFS population. We abstracted information on indicators covering several domains: preventive, diagnosis-specific, and chronic disease care. RESULTS On the indicators we created and tested, access in the single managed care plan under study was comparable to or better than FFS care in the same geographic region. Percent of Medicare recipients with breast cancer screening was 36 percentage points higher in the staff model versus FFS (95% confidence interval 34-38 percentage points). Follow up after hospitalization for myocardial infarction was 20 percentage points higher in the group model than in FFS (95% confidence interval 14-26 percentage points). CONCLUSION According to indicators developed for use in both claims and automated medical record data, access to care for elderly Medicare beneficiaries in one large managed care organization was as good as or better than that in FFS care in the same geographic area.

Abstract
While the management and prognosis of colorectal cancer are largely dependent on clinical features such as tumor stage, there is considerable variation in treatment and outcome not explained by traditional prognostic factors. To guide efforts by researchers and health-care providers to improve quality of care, we review studies of variation in treatment and outcome by patient and provider characteristics. Surgeon expertise and case volume are associated with improved tumor control, although surgeon and hospital factors are not associated consistently with perioperative mortality or long-term survival. Some studies indicate that patients are less likely to undergo permanent colostomy if they are treated by high-volume surgeons and hospitals. Differences in treatment and outcome of patients managed by health maintenance organizations or fee-for-service providers have not generally been found. Older patients are less likely to receive adjuvant therapy after surgery, even after adjustment for comorbid illness. In the United States, black patients with colorectal cancer receive less aggressive therapy and are more likely to die of this disease than white patients, but cancer-specific survival differences are reduced or eliminated when black patients receive comparable treatment. Patients of low socioeconomic status (SES) have worse survival than those of higher SES, although the reasons for this discrepancy are not well understood. Variations in treatment may arise from inadequate physician knowledge of practice guidelines, treatment decisions based on unmeasured clinical factors, or patient preferences. To improve quality of care for colorectal cancer, a better understanding of mechanisms underlying associations between patient and provider characteristics and outcomes is required.

Abstract
OBJECTIVES We hypothesized that health insurance payer and race might influence the care and outcomes of patients with colorectal cancer. METHODS We examined treatments received for all incident cases of colorectal cancer occurring in Florida in 1994 (n = 9551), using state tumor registry data. We also estimated the adjusted risk of death (through 1997), using proportional hazards regression analysis controlling for other predictors of mortality. RESULTS Treatments received by patients varied considerably according to their insurance payer. Among non-Medicare patients, those in the following groups had higher adjusted risks of death relative to commercial fee-for-service insurance: commercial HMO (risk ratio [RR] = 1.40; 95% confidence interval [CI] = 1.18, 1.67; P = .0001), Medicaid (RR = 1.44; 95% CI = 1.06, 1.97; P = .02), and uninsured (RR = 1.41; 95% CI = 1.12, 1.77; P = .003). Non-Hispanic African Americans had higher mortality rates (RR = 1.18; 95% CI = 1.01, 1.37; P = .04) than non-Hispanic Whites. CONCLUSIONS Patients with colorectal cancer who were uninsured or insured by Medicaid or commercial HMOs had higher mortality rates than patients with commercial fee-for-service insurance. Mortality was also higher among non-Hispanic African American patients.

Abstract
BACKGROUND The presence and type of health insurance may be an important determinant of cancer stage at diagnosis. To determine whether previously observed racial differences in stage of cancer at diagnosis may be explained partly by differences in insurance coverage, we studied all patients with incident cases of melanoma or colorectal, breast, or prostate cancer in Florida in 1994 for whom the stage at diagnosis and insurance status were known. METHODS The effects of insurance and race on the odds of a late stage (regional or distant) diagnosis were examined by adjusting for an individual's age, sex, marital status, education, income, and comorbidity. All P values are two-sided. RESULTS Data from 28 237 patients were analyzed. Persons who were uninsured were more likely diagnosed at a late stage (colorectal cancer odds ratio [OR] = 1.67, P =.004; melanoma OR = 2.59, P =.004; breast cancer OR = 1.43, P =.001; prostate cancer OR = 1.47, P =.02) than were persons with commercial indemnity insurance. Patients insured by Medicaid were more likely diagnosed at a late stage of breast cancer (OR = 1.87, P<.001) and melanoma (OR = 4.69, P<.001). Non-Hispanic African-American patients were more likely diagnosed with late stage breast and prostate cancers than were non-Hispanic whites. Hispanic patients were more likely to be diagnosed with late stage breast cancer but less likely to be diagnosed with late stage prostate cancer. CONCLUSIONS Persons lacking health insurance and persons insured by Medicaid are more likely diagnosed with late stage cancer at diverse sites, and efforts to improve access to cancer-screening services are warranted for these groups. Racial differences in stage at diagnosis are not explained by insurance coverage or socioeconomic status.

Abstract
OBJECTIVES This article compares the quality of care provided by managed care plans (MCPs) and indemnity (or fee-for-service [FFS]) plans since 1980. METHODS The 44 studies examined are the studies that Miller and Luft cited in their 1994 and 1997 reviews of the literature comparing MCPs with FFS plans. These studies are examined to determine how well they met Miller and Luft's selection criteria and, in addition, whether they controlled for differences in the breadth of insurance coverage. RESULTS The 44 studies generated 57 observations. MCPs scored better than FFS plans on 10 of these, equally well on 25, and worse on 22. However, only 44 of these observations met the Miller-Luft criteria plus the coverage criterion. Four of these indicated that MCP care was better, 19 that MCP and FFS care were equivalent, and 21 that MCP care was worse. CONCLUSIONS The small body of reliable studies comparing the quality of MCP care with that of FFS care indicates that the quality of care provided by MCPs tends to be equal or inferior to that provided by FFS plans.

Abstract
OBJECTIVES To review the high quality US evidence on performance of managed health care organisations and the available US evidence on specific managed care techniques; namely, financial incentives, utilisation management and review, physician profiling and disease management. METHODS Literature searches were conducted using numerous databases including Medline, Embase, the Social Sciences Citation Index and the National Health Service (NHS) Centre for Reviews and Dissemination library. For inclusion of evaluations of overall performance, studies had to use a comparison group (typically fee-for-service patients), make appropriate statistical adjustments for differences between groups, and be published in a peer-reviewed journal from 1980 forward. For assessments of techniques, less-demanding inclusion criteria reflected the paucity of generalisable literature; however, more current results were required (1990 forward). RESULTS We identified 70 articles for systematic review, covering 18 dimensions of performance (e.g. utilisation, quality of care, consumer satisfaction, equity). The strength of the evidence varied by dimension. It was strongest for utilisation and quality. In general, managed care seems to reduce hospitalisation and use of high-cost discretionary services, to increase preventive screening, and to be neutral in terms of patient outcomes. As for specific techniques, we identified 19 articles for review, but limitations of these studies prevented our drawing any definite conclusions about techniques' effectiveness. This is an important, if somewhat negative, conclusion. CONCLUSIONS Applying US evidence is complicated by an irrelevant comparator and a higher baseline of utilisation. Managed care brought Americans the familiar NHS practices of population-based health care and resource management through gatekeeping; hence, changes due to UK adoption of managed care techniques may be modest. US evidence should be used to generate hypotheses, not to predict UK behaviour.

Abstract
PURPOSE Surgical options for the treatment of rectal cancer may involve sphincter-sparing procedures (SSP) or abdominoperineal resection (APR). We sought to examine variations in the surgical treatment of rectal cancer for a large, well-defined patient population and specifically to determine if differences exist in management and survival based on hospital type and surgical caseload. METHODS The Cancer Surveillance Program database for Los Angeles County was used to retrospectively retrieve data on all patients who underwent SSP or APR for rectal adenocarcinoma between 1988 and 1992. RESULTS A total of 2,006 patients with adenocarcinoma of the rectum underwent SSP or APR during the study period. Overall, 55 percent underwent SSP, and the remaining 45 percent underwent APR. Use of SSP remained relatively constant for each year of the five-year period. Substantial variability was seen in the use of SSP at various hospital types. For localized disease, this varied from as low as 52 percent at teaching hospitals to as high as 78 percent at hospitals approved by the American College of Surgeons (P = 0.067). To examine the role of caseload experience, hospitals were divided into those completing an average of five or fewer rectal cancer cases per year vs. those completing an average of more than five cases per year. For localized disease, hospitals with higher caseloads performed SSP in significantly more cases, 69 vs. 63 percent (P = 0.049). Survival was seen to be significantly improved for patients operated on at hospitals with higher caseloads, in cases of both localized and regional diseases (P < 0.001). CONCLUSION Surgical choices in the treatment of rectal cancer may vary widely, even in a well-defined geographic region. Although the reasons for this variability are multifactorial, hospital environment and surgical caseload experience seem to have a significant role in the choice of surgical procedure and on survival.

Abstract
Although health maintenance organization (HMO) structures and databases are not uniform across plans, there are unique characteristics of HMO data in general that make them useful in examining health policy and delivery issues. The authors examine differences in data generated by different types of HMOs. After discussing why health services research using HMO data is needed by HMOs, other providers, practitioners, payers, and consumers of health care, the authors examine ways in which HMOs can provide sound answers to crucially important questions about the future of health care. They conclude that although the need for research on HMOs is compelling, researchers need to understand the information needs of HMOs and the incentives that are shaping the industry's approach to system delivery and clinical outcomes research. If HMOs do not take the lead in conducting health services research, they will diminish their role in shaping policies that will shape their future evolution.

Abstract
This article reviews twenty-four studies that compare health maintenance organization (HMO) use ofdiagnostic testing services tofee-for-service(FFS) use. Diagnosticservices contribute to both the high level and the growth of health care costs. This review of a series of studies is important because any single study is commonly limited to a small set of diagnostic tests and generally provides analysis restricted to one, or afew, HMOs. Combining evidence from each of the studies yields thefollowing conclusions. Relative to FFS enrollees, HMO enrollees receive fewer inpatient diagnostic tests. Evidence concerning HMO utilization of outpatient testing relative to FFS plans, though mixed, tends to suggest that HMOs do not perform more ofthese services and may performfewer for patients with chronic illnesses. Quality of care does not appear to suffer in HMOs despite lower testing rates, suggesting HMOs reduce testing in situations in which the incremental value is small.
