Pain management in the last six months of life among women who died of ovarian cancer.

Previous studies indicate that the symptoms of many dying cancer patients are undertreated and many suffer unnecessary pain. We obtained data retrospectively from three large health maintenance organizations, and examined the analgesic drug therapies received in the last six months of life by women who died of ovarian cancer between 1995 and 2000. Subjects were identified through cancer registries and administrative data. Outpatient medications used during the final six months of life were obtained from pharmacy databases. Pain information was obtained from medical charts. We categorized each medication based on the World Health Organization classification for pain management (mild, moderate, or intense). Of the 421 women, only 64 (15%) had no mention of pain in their charts. The use of medications typically prescribed for moderate to severe pain ("high intensity" drugs) increased as women approached death. At 5-6 months before death, 55% of women were either on no pain medication or medication generally used for mild pain; only 9% were using the highest intensity regimen. The percentage on the highest intensity regimen (drugs generally used for severe pain) increased to 22% at 3-4 months before death and 54% at 1-2 months. Older women (70 or older) were less likely to be prescribed the highest intensity medication than those under age 70 (44% vs. 70%, P<0.001). No differences were found in the use of the high intensity drugs by race, marital status, year of diagnosis, stage of disease, or comorbidity. Our finding that only 54% of women with pain were given high intensity medication near death indicates room for improvement in the care of ovarian cancer patients at the end of life.

Social support among women who died of ovarian cancer.

GOALS OF WORK: We investigated the effects of social support in the last 6 months of life for women who died of ovarian cancer. MATERIALS AND METHODS: The study population included women enrolled in one of three Managed Care Organizations who died of ovarian cancer (1995-2000). Information was collected on demographics, living environment, presence of escorts to oncology encounters, comorbidities, medications, outpatient and inpatient encounters, and referrals to home health and hospice. Two characteristics of social support were examined: living with others and being escorted to one or more oncology visits. RESULTS: Of 421 subjects, both aspects of social support were known for 345 (82%). Of these, 227 (66%) lived with others and were escorted, 33 (10%) lived with others but were never escorted, 59 (17%) lived alone but were escorted, and 26 (8%) lived alone and never were accompanied. Women living alone were less likely to be taking a psychotropic medication (57% vs 70%, p = 0.021) and were somewhat less likely to receive hospice referral (42% vs 53%, p = 0.054). Women who were never escorted had fewer outpatient encounters (12.60 vs 15.77, p = 0.033) and were less likely to be referred to home health (18% vs 30%, p = 0.046). CONCLUSIONS: This study indicates that social support has some beneficial effects on receipt of personal health services. Friends and family may act as proponents for the patient in obtaining services. Health care professionals should be encouraged to assess the cancer patient's social situation and identify areas where help may be needed.

Quality of life after bilateral prophylactic mastectomy.

BACKGROUND: Bilateral prophylactic mastectomy in women with increased breast cancer risk dramatically reduces breast cancer occurrence but little is known about psychosocial outcomes. METHODS: To examine long-term quality of life after bilateral prophylactic mastectomy, we mailed surveys to 195 women who had the procedure from 1979 to 1999 and to a random sample of 117 women at increased breast cancer risk who did not have the procedure. Measures were modeled on or drawn directly from validated instruments designed to assess quality of life, body image, sexuality, breast cancer concerns, depression, health perception, and demographic characteristics. We used logistic regression to examine associations between quality of life and other domains. RESULTS: The response rate was 58%, with 106 women with and 62 women without prophylactic mastectomy returning complete surveys. Among women who underwent bilateral prophylactic mastectomy, 84% were satisfied with their decision to have the procedure; 61% reported high contentment with quality of life compared with an identical 61% of women who did not have the procedure (P = 1.0). Among all subjects, diminished contentment with quality of life was not associated with bilateral prophylactic mastectomy but with dissatisfaction with sex life (adjusted ratio [OR] = 2.5, 95% confidence interval [CI] = 1.0-6.2), possible depression (CES-D > 16, OR = 4.9, CI = 2.0-11.8), and poor or fair general health perception (OR = 8.3, 95% CI = 2.4-29.0). CONCLUSIONS: The majority of women reported satisfaction with bilateral prophylactic mastectomy and experienced psychosocial outcomes similar to women with similarly elevated breast cancer risk who did not undergo prophylactic mastectomy. Bilateral prophylactic mastectomy appears to neither positively nor negatively impact long-term psychosocial outcomes.

Patterns and predictors of mammography utilization among breast cancer survivors.

BACKGROUND: Improvements in cancer detection and treatment have resulted in increasing numbers of breast cancer survivors. Information regarding the use of mammography by breast cancer survivors is limited. METHODS: The use of surveillance mammography was examined over a 5-year period in a retrospective cohort of women age>or=55 years who were diagnosed with incident primary breast cancer (1996-1997) while enrolled in 1 of 4 geographically diverse integrated health systems. RESULTS: Of the 797 women included in the study, 80% (n=636) underwent mammograms during the first year after treatment for breast cancer. The percentage of women having mammograms during each yearly period decreased significantly over time. In multivariable analyses, older women with comorbid illnesses or those with late-stage disease were less likely to undergo mammograms, whereas those who underwent breast-conserving therapy (adjusted odds ratio [OR] of 1.38 [95% confidence interval (95% CI), 1.09-1.75]) were more likely to have mammograms. Women who had outpatient visits with a gynecologist (adjusted OR of 3.49 [95% CI, 2.55-4.79]), or a primary care physician (adjusted OR of 2.21 [95% CI, 1.73-2.82]) during the year were more likely to undergo mammograms in that year. CONCLUSIONS: The use of mammography among breast cancer survivors declines over time. Efforts are needed to increase awareness among healthcare providers and breast cancer survivors of the value of follow-up mammography. The current findings highlight the importance of maintaining ongoing contact with primary care physicians and gynecologists.

Contentment with quality of life among breast cancer survivors with and without contralateral prophylactic mastectomy.

PURPOSE: To understand psychosocial outcomes after prophylactic removal of the contralateral breast in women with unilateral breast cancer. METHODS: We mailed surveys to women with contralateral prophylactic mastectomy after breast cancer diagnosis between 1979 and 1999 at six health care delivery systems, and to a smaller random sample of women with breast cancer without the procedure. Measures were modeled on instruments developed to assess contentment with quality of life, body image, sexual satisfaction, breast cancer concern, depression, and health perception. We examined associations between quality of life and the other domains using logistic regression. RESULTS: The response rate was 72.6%. Among 519 women who underwent contralateral prophylactic mastectomy, 86.5% were satisfied with their decision; 76.3% reported high contentment with quality of life compared with 75.4% of 61 women who did not undergo the procedure (P = .88). Among all case subjects, less contentment with quality of life was not associated with contralateral prophylactic mastectomy or demographic characteristics, but was associated with poor or fair general health perception (odds ratio [OR], 7.0; 95% CI, 3.4 to 14.1); possible depression (OR, 5.4; 95% CI, 3.1 to 9.2); dissatisfaction with appearance when dressed (OR, 3.5; 95% CI, 2.0 to 6.0); self-consciousness about appearance (OR, 2.0; 95% CI, 1.1 to 3.7); and avoiding thoughts about breast cancer (modest: OR, 2.2; 95% CI, 1.1 to 4.5; highest: OR, 1.7; 95% CI, 0.9 to 3.2). CONCLUSION: Most women undergoing contralateral prophylactic mastectomy report satisfaction with their decision and experience psychosocial outcomes similar to breast cancer survivors without the procedure.

Hormone use and patient concerns after the findings of the Women's Health Initiative.

OBJECTIVE: To assess behaviors and concerns related to hormone therapy after the findings of the Women's Health Initiative (WHI). DESIGN: A survey was mailed to a random sample of 1,200 women identified through the pharmacy database as taking one of two estrogen + progestogen therapies (EPT) during the 6-month period before the publication of WHI findings. Questions included hormone use history, changes in usage, an assessment of symptoms, symptom changes, health behavior changes, use of alternative therapies, and demographics. RESULTS: The response rate was 70%, with women in their 60s and those receiving hormone therapy for 5 or more years were more likely to respond (P < 0.05). The majority had started hormones for symptom relief (69%) and expected to continue use. Many reported discontinuation (63%) or modifying their medication (18%). Half of these women stopped then restarted, the other half changed products. Women in their 50s were more likely to remain on hormones than older women (P < 0.01), and those taking ethinyl estradiol and norethindrone acetate were more likely to remain on their medication than those on conjugated estrogens (43% vs 29%, P < 0.01). Little change was reported in exercise and 19% increased their calcium intake. Patient concerns fell into five major categories: long-term effects, symptom control, breast cancer risk, bone health, and cognitive function. CONCLUSIONS: Women seem to be heeding the warnings about hormones but remain concerned about the potential long-term sequelae and symptom control. More research is needed to identify safer approaches to symptom relief and to address the concerns expressed.

Impact of IRB requirements on a multicenter survey of prophylactic mastectomy outcomes.

OBJECTIVE: This study assesses the variability in requirements among six institutional review boards (IRBs) and the resulting protocol variations for a multicenter mailed survey. STUDY DESIGN AND SETTING: We utilized a cross-sectional mailed survey to gather information on long-term psychosocial outcomes of prophylactic mastectomy among women at six health maintenance organizations, all of which are part of the Cancer Research Network. In the context of this collaborative study, we characterized the impact of the different sites' IRB review processes on the study protocol and participation. RESULTS: IRB review resulted in site differences in physician consent prior to participant contact, invitation letter content and signatories, and incentive type. The review process required two to eight modifications beyond the initial application and resulted in unanticipated delays and costs. CONCLUSION: Site-to-site variability in IRB requirements may adversely impact scientific rigor and delay implementation of collaborative studies, especially when not considered in project planning. IRB review is an essential aspect of research but one that can present substantial challenges for multicenter studies.

Self-reported hypertension treatment beliefs and practices of primary care physicians in a managed care organization.

BACKGROUND: Blood pressure (BP) is controlled to recommended goal in less than one-third of people with hypertension. There has been little recent research on physician beliefs and practices with regard to the treatment of hypertension. METHODS: In late 1999, we surveyed 104 primary care physicians in the 18 owned clinics of a large staff model, non-profit health maintenance organization. The survey included questions about demographics, BP treatment goals for patients with uncomplicated hypertension, and beliefs about hypertension. RESULTS: The reported systolic BP treatment goal was < or =140 mm Hg for 97% and the diastolic BP goal was < or =90 mm Hg for 100%. The systolic BP goal for patients with isolated systolic hypertension was < or =140 mm Hg for 82%, but 34% stated that they would treat to a different goal depending on the diastolic BP. The proportions of physicians who would intensify treatment for BP of 140/90 mm Hg, 150/95 mm Hg, 165/75 mm Hg, and 165/65 mm Hg were 64%, 97%, 89% and 77%, respectively. Although 93% believed that medication was necessary to control BP in most cases, a majority (55%) agreed with the statement that BP could be controlled in most patients with only one drug. Although 42% reported that they often had to change drugs because of side effects, only 16% believed that it was time-consuming to find a well-tolerated drug regimen. CONCLUSIONS: In this setting, primary care physicians' self-reported practices were in good agreement with national guidelines put forth in the late 1990s, and their beliefs were favorable to therapy. Our data point to a need for interventions to emphasize that combination drug therapy is frequently required to achieve BP control, and that more aggressive intervention is often warranted for isolated systolic hypertension.

Building a research consortium of large health systems: the Cancer Research Network.

Critical questions about cancer prevention, care, and outcomes increasingly require research involving large patient populations and their care delivery organizations. The Cancer Research Network (CRN) includes 11 integrated health systems funded by the National Cancer Institute (NCI) to conduct collaborative cancer research. This article describes the challenges of constructing a productive consortium of large health systems, and explores the CRN's responses. The CRN was initially funded through an NCI cooperative agreement in 1999 and has since received a second 4-year grant. Leadership and policy development are provided through a steering committee, subcommittees, and an external advisory committee. The CRN includes integral and affiliated research projects supported by a Scientific and Data Resources Core. Three characteristics of the CRN intensified the general challenges of consortium research: 1) its members are large health systems with legitimate concerns about confidentiality of data about enrollees, providers, and the organization; 2) CRN research projects often generate highly sensitive data about quality of care; and therefore 3) each participating organization wants a strong voice in CRN direction. CRN experience to date confirms that a consortium of health systems with internal research capacity can address a range of important cancer research questions that would be difficult to study in other venues. The advantages and challenges of consortium research are explored, with suggestions for the development, execution, and management of multisystem population laboratories.

Complications following bilateral prophylactic mastectomy.

BACKGROUND: Bilateral prophylactic mastectomy significantly decreases breast cancer risk, but complications of the procedure have only been described in single-site studies. We describe the frequency and type of complications in women who underwent bilateral prophylactic mastectomy in a multisite community-based cohort. METHODS: Women aged 18-80 years undergoing bilateral prophylactic mastectomy without a personal history of breast cancer at one of six health plans were eligible. We identified women from automated data sources, then reviewed hospital data, ambulatory notes, and other chart elements to confirm eligibility and obtain all charted information about complications and surgeries performed after prophylactic mastectomy, including reconstructive procedures. Reconstructions were characterized by type (implant vs. tissue graft). Complications were noted for a 1-year period after any surgical procedure. RESULTS: We identified 269 women with prophylactic mastectomy who were followed for a mean of 7.4 years. Their mean age was 44.9 years. Nearly 80% undertook reconstruction, most with prosthetic implants. One or more complications occurred in 64%. The most common complications were pain (35% of women), infection (17%), and seroma (17%). Women with no reconstruction had fewer complications (mean of .93) than women who had implant (2.0) or tissue graft (2.4) reconstruction procedures (differences from no reconstruction: 1.07 [95% confidence interval = 0.36 to 1.77] and 1.50 [95% confidence interval = 0.44 to 2.56] respectively). Delay of reconstruction after mastectomy was associated with a borderline-significant higher risk of complications (80.6%) compared to simultaneous reconstruction (64.0%, P = .055). CONCLUSION: We found that almost two-thirds of women undergoing bilateral prophylactic mastectomy had at least one complication following surgery. Further work should be done to minimize and to understand the effect of complications of bilateral prophylactic mastectomy.

Screening clinical breast examination: how often does it miss lethal breast cancer?

BACKGROUND: Although most American women regularly receive screening clinical breast examination (CBE), little is known about CBE accuracy in community practice. We sought to estimate the rate of cancer detection (sensitivity) of screening CBE performed by community-based clinicians on women who ultimately died of breast cancer, as well as to identify factors associated with accurate detection. SUBJECTS AND METHODS: We evaluated CBE accuracy among asymptomatic female health plan enrollees in five states (WA, OR, CA, MA, and MN) who received a CBE within 1 year of breast cancer diagnosis and who died of breast cancer within 15 years of diagnosis (N = 485). Sensitivity was estimated as the proportion whose exam was abnormal. Bivariate and logistic regression analyses identified patient characteristics associated with cancer detection. RESULTS: An abnormality was noted on screening CBE in one of five women who ultimately succumbed to breast cancer (sensitivity = 21.6%; 95% confidence interval [CI] = 18.1% to 25.6%). The odds of a true-positive screening CBE (sensitivity) were decreased among women using estrogen (odds ratio [OR] = 0.23; 95% CI = 0.07 to 0.80), receiving a Pap smear during the same visit as CBE (OR = 0.45; 95% CI = 0.27 to 0.72), and with increasing chronic disease comorbidity (P(trend) = .08). CONCLUSION: Screening CBE as performed in the community may be insufficiently sensitive to detect most lethal breast cancers. Low sensitivity of screening CBE in community practice may be partly attributable to its performance alongside time-consuming clinical tasks such as Pap smear screening or chronic illness care.

Comparing breast cancer case identification using HMO computerized diagnostic data and SEER data.

OBJECTIVE: To determine the sensitivity and positive predictive value (PPV) of computerized diagnostic data from health maintenance organizations (HMOs) in identifying incident breast cancer cases. STUDY DESIGN: An HMO without a cancer registry developed an algorithm identifying incident breast cancer cases using computerized diagnostic codes. Two other HMO sites with Surveillance, Epidemiology, and End Results (SEER) registries duplicated this case-identification approach. Using the SEER registries as the criterion standard, we determined the sensitivity and PPV of the computerized data. METHODS: Data were collected from HMO computerized data-bases between January 1, 1996, and December 31, 1999. Surveillance, Epidemiology, and End Results data were also used. RESULTS: The overall sensitivity of the HMO databases was between 0.92 (95% confidence interval [CI], 0.91-0.96) and 0.99 (95% CI, 0.98-0.99). Sensitivity was high (range, 0.94-0.98), for the first 3 (of 4) years, dropping slightly (range, 0.81-0.94) in the last year. The overall PPV ranged from 0.34 (95% CI, 0.32-0.35) to 0.44 (95% CI, 0.42-0.46). Positive predictive value rose sharply (range, 0.18-0.20) after the first year to 0.83 and 0.92 in the last year because prevalent cases were excluded. Review of a random sample of 50 cases identified in the computerized data-bases but not by SEER data indicated that, while SEER usually identified the cases, the registry did not associate every case with the health plan. CONCLUSIONS: Health maintenance organization computerized databases were highly sensitive for identifying incident breast cancer cases, but PPV was low in the initial year because the systems did not differentiate between prevalent and incident cases. Health maintenance organizations depending solely on SEER data for cancer case identification will miss a small percentage of cases.

Identification of children with special health care needs within a managed care setting.

OBJECTIVE: To assess 2 established methods of identifying children with special health care needs (CSHCN) within a health plan population for intensified service coordination. METHODS: The tools tested were the Questionnaire for Identifying Children With Chronic Conditions (QuICCC) and the Clinical Risk Grouper (CRG) software. The QuICCC was administered by telephone to the parents of 517 children. The CRG software tool was then applied to the health plan database. The accuracy of identifying the target population was assessed by a single trained reviewer by comparison with the comprehensive medical record. RESULTS: According to the QuICCC, 37.1% of the parents surveyed had CSHCN. According to the CRG, 11% of the health plan's pediatric population was categorized as CSHCN. The medical record review agreed with overall QuICCC findings in 53% to 61% of cases and overall CRG findings in 66% to 73% of cases. CONCLUSIONS: Administering the QuICCC was a time- and labor-intensive endeavor with a relatively low overall level of sensitivity. The CRG was less labor intensive with slightly higher sensitivity. Identifying the target population in an effective and efficient manner remains a challenge for health plans.

Geriatric depression, antidepressant treatment, and healthcare utilization in a health maintenance organization.

OBJECTIVES: To assess the separate effects of depressive symptoms and antidepressant treatment on healthcare utilization and cost. SETTING: Social Health Maintenance Organization (HMO) at HealthPartners in Minnesota. PARTICIPANTS: Geriatric Social HMO enrollees were screened for depressive symptoms using the 30-item Geriatric Depression Scale. A stratified sample was created, composed of geriatric enrollees with depressive symptoms, with antidepressant prescriptions, or with neither (n = 516). DESIGN: Regression analyses were conducted with separate equations for utilization and charge outcome variables, both outpatient and inpatient (log-transformed). The Charlson Comorbidity Index, age, and gender served as covariates. MEASUREMENT: Depressive symptoms were identified through the Diagnostic Interview Schedule. Antidepressant treatment was determined from the HMO pharmacy database. RESULTS: Having depressive symptoms was associated with a 19 increase in the number of outpatient encounters and a 30 increase in total outpatient charges. Antidepressant treatment was associated with a 32 increase in total outpatient charges but was not significantly associated with number of outpatient encounters. Depressive symptoms and antidepressant therapy were not significantly associated with inpatient utilization or charges. CONCLUSION: This study found that patients with depressive symptoms generated more outpatient health care and higher charges but not necessarily more inpatient care. Our findings suggest that programs targeted to geriatric patients whose depression is comorbid with other chronic medical conditions might be cost-effective and particularly appropriate for geriatric care.

How acceptable are financial incentives and written feedback for improving hypertension control? Perspectives from physicians, clinic administrators, and patients.

OBJECTIVES: To assess attitudes of physicians, clinic administrators, and patients within a health maintenance organization (HMO) toward using financial incentives to improve the control of hypertension. STUDY DESIGN: Descriptive study of attitudes toward use of financial incentives paid to physicians or to clinic systems. METHODS: Data were collected through physician survey (n = 104), interviews with clinic administrators (n = 24), and patient focus groups (n = 3) during the winter of 1999 and the spring of 2000. Analyses included both qualitative and quantitative approaches. RESULTS: Most physicians (80%) supported additional funding to clinics to create systems to improve hypertension care. However, less than half supported direct payment to either groups of physicians (38%) or individual physicians (24%). Sixty-four percent of clinic administrators supported incentive payments to clinics to improve quality of care, whereas only 42% favored incentives to physicians. Patients had a uniformly favorable view of incentives paid to clinics, but were strongly opposed to direct physician incentives. Written feedback was supported by both clinic administrators (54%) and physicians (74%). CONCLUSIONS: In this nonprofit HMO, none of the stakeholder groups supported direct incentive payments to physicians to improve hypertension control. Trials of financial incentives within managed care organizations should include study arms with clinic-based incentives. Further study is needed to determine if incentives to clinics, which appear to be acceptable, can actually improve blood pressure control.

Smoking cessation attempts in relation to prior health care charges: the effect of antecedent smoking-related symptoms?

PURPOSE: We hypothesize that elevated charges among former smokers reflect differential cessation of sicker individuals. We ascertained the relationship between prior health care charges and time to smoking cessation. DESIGN: Prospective, observational study using panel survey data and administrative health plan records. SETTING: A large managed care organization in Minnesota. SUBJECTS: A stratified random sample of 8000 health plan members 40 years and older, yielding 611 current smokers at baseline. MEASURES: Smoking cessation measured via self-report survey. Health care charges, mortality, and disenrollment data derived from automated health plan databases. RESULTS: Among smoking adults without chronic disease diagnoses at baseline, a first attempt at quitting smoking was positively associated with the presence of any inpatient charges (relative risk [RR], 1.9; p < .05) or any emergency department or urgent care charges (RR, 1.4; p < .10). We also observed positive associations between total charges and ambulatory charges in the top textile (RR, 1.5 and 1.6, respectively; p < .05) with a first attempt at quitting smoking, further suggesting graded relationships. Among smoking adults with one or more of four chronic disease diagnoses at baseline, being in the top two tertiles of total charges or ambulatory care charges was predictive of a subsequent attempt at quitting smoking. CONCLUSIONS: Higher health care charges, particularly from ambulatory (primary care clinic) settings, predicted smoking cessation among both individuals with and without chronic diseases. These charges may be proxies for other factors, such as smoking-related symptoms or physician advice or messaging regarding smoking cessation.
