RESUMO
INTRODUCTION: Smoking is the leading preventable cause of death and disability in the United States (US). A 2019 randomized controlled trial found e-cigarettes are more effective than nicotine replacement therapy (NRT) in achieving abstinence when both are combined with behavioral counselling. Few cost-effectiveness studies have been performed regarding e-cigarettes as an adjunct to cessation efforts, and none in a US context. This study evaluated the cost-effectiveness of e-cigarettes compared to NRT, both with counselling, as cessation aids for Medicaid smokers in California. METHODS: A cost-effectiveness analysis from a US societal perspective comparing e-cigarettes with NRT was constructed. Using a lifetime horizon, smokers were followed to different health states to their expected lifespan. Costs were expressed in 2020 US dollars and health outcomes in quality-adjusted life years. All costs and outcomes were discounted at a 3% annual rate and model findings were assessed with a series of sensitivity analyses. RESULTS: Using US willingness-to-pay thresholds, e-cigarettes were more cost-effective than NRT, with an incremental cost-effectiveness ratio of $11,454 per additional QALY gained over smokers' lifetimes. Results were sensitive to smokers' healthcare costs, model start ages, discount rate, and QALY weights. CONCLUSIONS: E-cigarettes used as a cessation treatment by smokers are more cost-effective relative to NRT. However, e-cigarettes as a treatment are currently unapproved by the Food and Drug Administration (FDA). Despite lack of FDA approval, e-cigarettes are a popular choice among smokers trying to quit. Policymakers should consider whether providing financial support for e-cigarettes as a harm reduction strategy is worth pursuing. IMPLICATIONS: As e-cigarettes grow in popularity and are an increasingly preferred choice of smoking cessation aid among smokers attempting to quit, it is important to examine the inclusion of these products in tobacco policy, research, and practice. Several countries have now adopted or are in the process of adopting e-cigarettes as a medically licensed and regulated smoking cessation aid. Future smoking cessation strategies by US policymakers may consider the adoption of e-cigarettes as a cost-effective harm reduction tool for use by current smokers seeking to quit.
RESUMO
BACKGROUND: Local transportation agencies implementing Vision Zero road safety improvement projects often face opposition from business owners concerned about the potential negative impact on their sales. Few studies have documented the economic impact of these projects. METHODS: We examined baseline and up to 3 years of postimprovement taxable sales data for retail, food and service-based businesses adjacent to seven road safety projects begun between 2006 and 2014 in Seattle. We used hierarchical linear models to test whether the change in annual taxable sales differed between the 7 intervention sites and 18 nearby matched comparison sites that had no road safety improvements within the study time frame. RESULTS: Average annual taxable sales at baseline were comparable at the 7 intervention sites (US$44.7 million) and the 18 comparison sites (US$56.8 million). Regression analysis suggests that each additional year following baseline was associated with US$1.20 million more in taxable sales among intervention sites and US$1.14 million more among comparison sites. This difference is not statistically significant (p=0.64). Sensitivity analyses including a random slope, using a generalised linear model and an analysis of variance did not change conclusions. DISCUSSION: Results suggest that road safety improvement projects such as those in Vision Zero plans are not associated with adverse economic impacts on adjacent businesses. The absence of negative economic impacts associated with pedestrian and bicycle road safety projects should reassure local business owners and may encourage them to work with transportation agencies to implement Vision Zero road safety projects designed to eliminate traffic-related injuries.
RESUMO
OBJECTIVES: There is limited knowledge about the cost patterns of patients who receive a diagnosis of de novo and recurrent advanced cancers in the United States. METHODS: Data on patients who received a diagnosis of de novo stage IV or recurrent breast, colorectal, or lung cancer between 2000 and 2012 from 3 integrated health systems were used to estimate average annual costs for total, ambulatory, inpatient, medication, and other services during (1) 12 months preceding de novo or recurrent diagnosis (preindex) and (2) diagnosis month through 11 months after (postindex), from the payer perspective. Generalized linear regression models estimated costs adjusting for patient and clinical factors. RESULTS: Patients who developed a recurrence <1 year after their initial cancer diagnosis had significantly higher total costs in the preindex period than those with recurrence ≥1 year after initial diagnosis and those with de novo stage IV disease across all cancers (all P < .05). Patients with de novo stage IV breast and colorectal cancer had significantly higher total costs in the postindex period than patients with cancer recurrent in <1 year and ≥1 year (all P < .05), respectively. Patients in de novo stage IV and those with recurrence in ≥1 year experienced significantly higher postindex costs than the preindex period (all P < .001). CONCLUSIONS: Our findings reveal distinct cost patterns between patients with de novo stage IV, recurrent <1-year, and recurrent ≥1-year cancer, suggesting unique care trajectories that may influence resource use and planning. Future cost studies among patients with advanced cancer should account for de novo versus recurrent diagnoses and timing of recurrence to obtain estimates that accurately reflect these care pattern complexities.

BACKGROUND: Although one third of Medicare beneficiaries are enrolled in Medicare Advantage (MA) plans, there is limited information about the cost of treating Alzheimer disease and related dementias (ADRD) in these settings. OBJECTIVE: The objective of this study was to estimate direct health care costs attributable to ADRD among older adults within a large MA plan. RESEARCH DESIGN: A retrospective cohort design was used to estimate direct total, outpatient, inpatient, ambulatory pharmacy, and nursing home costs for 3 years before and after an incident ADRD diagnosis for 927 individuals diagnosed with ADRD relative to a sex-matched and birth year-matched set of 2945 controls. SUBJECT: Adults 65 years of age and older enrolled in the Kaiser Permanente Washington MA plan and the Adult Changes in Thought (ACT) Study, a prospective longitudinal cohort study of ADRD and brain aging. MEASURES: Data on monthly health service use obtained from health system electronic medical records for the period 1992-2012. RESULTS: Total monthly health care costs for individuals with ADRD are statistically greater (P<0.05) than controls beginning in the third month before diagnosis and remain significantly greater through the eighth month following diagnosis. Greater total health costs are driven by significantly (P<0.05) greater nursing home costs among individuals diagnosed with ADRD beginning in the third month prediagnosis. Although total costs were no longer significantly greater at 8 months following diagnosis, nursing home costs remained higher for the people with dementia through the 3 years postdiagnosis we analyzed. CONCLUSION: Greater total health care costs among individuals with ADRD are primarily driven by nursing home costs.

Background: The high economic burden of cancer is projected to continue growing. Cost-of-care estimates are key inputs for comparative effectiveness and economic analyses that aim to inform policies associated with cancer care. Existing estimates are based largely on SEER-Medicare data in the elderly, leaving a knowledge gap regarding costs for patients aged <65 years. Methods: We estimated total and net medical care costs using data on individuals diagnosed with breast, colorectal, lung, or prostate cancer (n=45,522) and noncancer controls (n=314,887) enrolled in 1 of 4 participating health plans. Net costs were defined as the difference in mean total costs between patients with cancer and controls. The phase-of-care approach and Kaplan-Meier Sample Average method were used to estimate mean total and net 1- and 5-year costs (in 2015 US dollars) by cancer site, stage at diagnosis, and age group (<65 and ≥65 years). Results: Total and net costs were consistently highest for lung cancer and lowest for prostate cancer. Net costs were higher across all cancer sites for patients aged <65 years than those aged ≥65 years. Medical care costs for all cancers increased with advanced stage at diagnosis. Conclusions: This study improves understanding of medical care costs for the 4 most common invasive cancers in the United States. Higher costs among patients aged <65 years highlight limitations of relying on SEER-Medicare data alone to understand the national burden of cancer, whereas higher costs for patients with advanced-stage cancer underscore the importance of early detection to curtail high long-term costs. These cost estimates can be used in the development and evaluation of interventions and policies across the cancer care continuum.

BACKGROUND: The US Preventive Services Taskforce (USPSTF) recommends routine lipid screening beginning age 35 for men [1]. For women age 20 and older, as well as men age 20-34, screening is recommended if cardiovascular risk factors are present. Prior research has focused on underutilization but not overuse of lipid testing. The objective is to document over- and under-use of lipid testing in an insured population of persons at low, moderate and high cardiovascular disease (CVD) risk for persons not already on statins. METHODS: The study is a retrospective cohort study that included all adults without prior CVD who were continuously enrolled in a large integrated healthcare system from 2005 to 2010. Measures included lipid test frequency extracted from administrative data and Framingham cardiovascular risk equations applied using electronic medical record data. Five year lipid testing patterns were examined by age, sex and CVD risk. Generalized linear models were used to estimate the relative risk for over testing associated with patient characteristics. RESULTS: Among males and females for whom testing is not recommended, 35.8 % and 61.5 % received at least one lipid test in the prior 5 years and 8.4 % and 24.4 % had two or more. Over-testing was associated with age, race, comorbidity, primary care use and neighborhood income. Among individuals at moderate and high-risk (not already treated with statins) and for whom screening is recommended, between 21.4 % and 25.1 % of individuals received no screening in the prior 5 years. CONCLUSIONS: Based on USPSTF lipid screening recommendations, this study documents substantial over-testing among individuals with low CVD risk and under-testing among individuals with moderate to high-risk not already on statins. Opportunity exists to better focus lipid screening efforts appropriate to CVD risk.

BACKGROUND: Little is known about how delivery of primary care in the patient-centered medical home (PCMH) influences outpatient specialty care use. OBJECTIVE: To describe changes in outpatient specialty use among patients with treated hypertension during and after PCMH practice transformation. DESIGN: One-group, 48-month interrupted time series across baseline, PCMH implementation and post-implementation periods. PATIENTS: Adults aged 18-85 years with treated hypertension. INTERVENTION: System-wide PCMH redesign implemented across 26 clinics in an integrated health care delivery system, beginning in January 2009. MAIN MEASURES: Resource Utilization Band variables from the Adjusted Clinical Groups case mix software characterized overall morbidity burden (low, medium, high). Negative binomial regression models described adjusted annual differences in total specialty care visits. Poisson regression models described adjusted annual differences in any use (yes/no) of selected medical and surgical specialties. KEY RESULTS: Compared to baseline, the study population averaged 7% fewer adjusted specialty visits during implementation (P < 0.001) and 4% fewer adjusted specialty visits in the first post-implementation year (P = 0.02). Patients were 12% less likely to have any cardiology visits during implementation and 13% less likely during the first post-implementation year (P < 0.001). In interaction analysis, patients with low morbidity had at least 27% fewer specialty visits during each of 3 years following baseline (P < 0.001); medium morbidity patients had 9% fewer specialty visits during implementation (P < 0.001) and 5% fewer specialty visits during the first post-implementation year (P = 0.007); high morbidity patients had 3% (P = 0.05) and 5% (P = 0.009) higher specialty use during the first and second post-implementation years, respectively. CONCLUSIONS: Results suggest that more comprehensive primary care in this PCMH redesign enabled primary care teams to deliver more hypertension care, and that many needs of low morbidity patients were within the scope of primary care practice. New approaches to care coordination between primary care teams and specialists should prioritize high morbidity, clinically complex patients.

PURPOSE: Telephone- and Internet-based communication are increasingly common in primary care, yet there is uncertainty about how these forms of communication affect demand for in-person office visits. We assessed whether use of copay-free secure messaging and telephone encounters was associated with office visit use in a population with diabetes. METHODS: We used an interrupted time series design with a patient-quarter unit of analysis. Secondary data from 2008-2011 spanned 3 periods before, during, and after a patient-centered medical home (PCMH) redesign in an integrated health care delivery system. We used linear regression models to estimate proportional changes in the use of primary care office visits associated with proportional increases in secure messaging and telephone encounters. RESULTS: The study included 18,486 adults with diabetes. The mean quarterly number of primary care contacts increased by 28% between the pre-PCMH baseline and the postimplementation periods, largely driven by increased secure messaging; quarterly office visit use declined by 8%. In adjusted regression analysis, 10% increases in secure message threads and telephone encounters were associated with increases of 1.25% (95% CI, 1.21%-1.29%) and 2.74% (95% CI, 2.70%-2.77%) in office visits, respectively. In an interaction model, proportional increases in secure messaging and telephone encounters remained associated with increased office visit use for all study periods and patient subpopulations (P<.001). CONCLUSIONS: Before and after a medical home redesign, proportional increases in secure messaging and telephone encounters were associated with additional primary care office visits for individuals with diabetes. Our findings provide evidence on how new forms of patient-clinician communication may affect demand for office visits.

BACKGROUND: Little is known about the medical care resources devoted to diagnosing and treating cancer-related symptoms before a definitive cancer diagnosis. Previous research using SEER-Medicare data to measure incremental costs and utilization associated with cancer started with the date of diagnosis. We hypothesized that health care use increases before diagnosis of a new primary cancer. METHODS: We used a longitudinal case-control design to estimate incremental medical care utilization rates. Cases were 121,293 persons enrolled between January 2000 and December 2008 with ≥1 primary cancers. We selected 522,839 controls randomly from among all health plan members who had no tumor registry evidence of cancer before January 2009, and we frequency matched controls to cancer cases on a 5:1 ratio by age group, sex, and having health plan eligibility in the year of diagnosis of the index cancer case. Utilization data were extracted for all cases and controls for the period 2000 to 2008 from standardized distributed data warehouses. To determine when and the extent to which patterns of medical care use change preceding a cancer diagnosis, we compute hospitalization rates, hospital days, emergency department visits, same-day surgical procedures, ambulatory medical office visits, imaging procedures, laboratory tests, and ambulatory prescription dispensings per 1000 persons per month within integrated delivery systems. RESULTS: One- to 3-fold increases in monthly utilization rates were observed during the 3 to 5 months before a cancer diagnosis, compared with matched noncancer control groups. This pattern was consistent for both aged and nonaged cancer patients. Aged cancer patients had higher utilization rates than nonaged cancer patients throughout the year before a cancer diagnosis. CONCLUSIONS: The prediagnosis phase is a resource-intensive component of cancer care episodes and should be included in cost of cancer estimates. More research is needed to determine whether reliable prognostic markers can be identified as the start of a cancer episode before a pathology-based diagnosis.

BACKGROUND: Most data regarding medical care for cancer patients in the United States comes from Surveillance, Epidemiology and End Results-linked Medicare analyses of individuals aged 65 years or older and typically excludes Medicare Advantage enrollees. OBJECTIVES: To assess the accuracy of chemotherapy and hormone therapy treatment data available through the Cancer Research Network's Virtual Data Warehouse (VDW). RESEARCH DESIGN: Retrospective, longitudinal cohort study. Medical record-abstracted, tumor registry-indicated treatments (gold standard) were compared with VDW-indicated treatments derived from health maintenance organization pharmacy, electronic medical record, and claim-based data systems. SUBJECTS: Enrollees aged 18 years and older diagnosed with incident breast, colorectal, lung, or prostate cancer from 2000 through 2007. MEASURES: Sensitivity, specificity, and positive predictive value were computed at 6 and 12 months after cancer diagnosis. RESULTS: Approximately 45% of all cancer cases (total N=23,800) were aged 64 years or younger. Overall chemotherapy sensitivity/specificities across the 3 health plans for incident breast, colorectal, lung, and prostate cancer cases were 95%/90%, 95%/93%, 93%/93%, and 85%/77%, respectively. With the exception of prostate cancer cases, overall positive predictive value ranged from 86% to 89%. Small variations in chemotherapy data accuracy existed due to cancer site and data source, whereas greater variation existed in hormone therapy capture across sites. CONCLUSIONS: Strong concordance exists between gold standard tumor registry measures of chemotherapy receipt and Cancer Research Network VDW data. Health maintenance organization VDW data can be used for a variety of studies addressing patterns of cancer care and comparative effectiveness research that previously could only be conducted among elderly Surveillance, Epidemiology and End Results-Medicare populations.

PURPOSE: The patient-centered medical home (PCMH) is being rapidly deployed in many settings to strengthen US primary care, improve quality, and control costs; however, evidence supporting this transformation is still lacking. We describe the Group Health experience in attempting to replicate the effects on health care use seen in a PCMH prototype clinic via a systemwide spread using Lean as the change strategy. METHODS: We used an interrupted time series analysis with a patient-month unit of analysis over a 4-year period that included baseline, implementation, and stabilization periods for 412,943 patients. To account for secular trends across these periods, we compared changes in use of face-to-face primary care visits, emergency department visits, and inpatient admissions with those of a nonequivalent comparison group of patients served by community network practices. RESULTS: After accounting for secular trends among network patients, patients empaneled to the PCMH clinics had 5.1% and 6.7% declines in primary care office visits in early and later stabilization years, respectively, after the implementation year. This trend was accompanied by a 123% increase in the use of secure electronic message threads and a 20% increase in telephone encounters. Declines were also seen in emergency department visits at 1 and 2 years (13.7% and 18.5%) compared with what would be expected based on secular trends in network practices. No statistically significant changes were found for hospital admissions. CONCLUSIONS: The Group Health experience shows it is possible to reduce emergency department use with PCMH transformation across a diverse set of clinics using a clear change strategy (Lean) and sufficient resources and supports.

BACKGROUND: Evidence-based guidelines recommend routine surveillance, including office visits and testing, to detect new and recurrent disease among survivors of breast and colorectal cancer. The extent to which surveillance practice is consistent with guideline recommendations or may vary by age is not known. METHODS: Cohorts of adult patients diagnosed with breast (n = 6205) and colorectal (n = 2297) cancer between 2000 and 2008 and treated with curative intent in 4 geographically diverse managed care environments were identified via tumor registries. Kaplan-Meier estimates were used to describe time to initial and subsequent receipt of surveillance services. Cox proportional hazards models evaluated the relation between patient characteristics and receipt of metastatic screening. RESULTS: Within 18 months of treatment, 87.2% of breast cancer survivors received recommended mammograms, with significantly higher rates noted for patients aged 50 years to 65 years. Among survivors of colorectal cancer, only 55.0% received recommended colon examinations, with significantly lower rates for those aged ≥ 75 years. The majority of breast (64.7%) and colorectal (73.3%) cancer survivors received nonrecommended metastatic disease testing. In patients with breast cancer, factors associated with metastatic disease testing include white race (hazards ratio [HR], 1.13), comorbidities (HR, 1.17), and younger age (HR, 1.13; 1.15; 1.13 for age groups: <50, 50-64, and 65-74 respectively). In those with colorectal cancer, these factors included younger age (HR, 1.31; 1.25 for age groups: <50 and 50-64 respectively) and comorbidities (HR, 1.10). CONCLUSIONS: Among an insured population, wide variation regarding the use of surveillance care was found by age and relative to guideline recommendations. Breast cancer survivors were found to have high rates of both guideline-recommended recurrence testing and non-guideline-recommended metastatic testing. Only approximately 50% of colorectal cancer survivors received recommended tests but greater than 67% received metastatic testing.

OBJECTIVE: Research suggests Medicaid expansion led to modest increases in the use of dental services among low-income adults, especially in states with more generous Medicaid dental benefits. We expand upon this research by examining whether the effect of Medicaid expansion differed across important socioeconomic subgroups. METHODS: Using Behavioral Risk Factor Surveillance System data from 2012 to 2016, we employed a difference-in-differences framework to estimate the effect of Medicaid expansion on annual use of dental services overall and by whether states offered more-than-emergency Medicaid dental benefits. We used generalized linear mixed-effects model trees to estimate effects across socioeconomic subgroups (e.g., age, education, race, income). RESULTS: The effect of Medicaid expansion varied by state's generosity of Medicaid dental coverage and combinations of socioeconomic subgroups. Overall, there was no significant association between Medicaid expansion and probability of using dental services (-0.1 pp percentage points [pp], p = 0.914). Medicaid expansion was associated with a modest increase in the probability of using dental services in states with more-than-emergency Medicaid dental benefits (2.3 pp, p < 0.001) and with a modest decrease in states with no or emergency-only benefits (-4.3 pp, p < 0.001). Among adults aged 21-35 without a high school diploma, Medicaid expansion was associated with an 8.1 pp (p = 0.003) increase in dental use probability, but there were no associated effects of Medicaid expansion for other subgroups. CONCLUSIONS: While Medicaid expansion alone is not sufficient to ensure adults receive recommended dental care, some vulnerable subgroups appear to have benefited. Efforts to mitigate barriers to dental care may be needed to increase uptake of dental services by low-income adults.

BACKGROUND: Patient-shared electronic health records provide opportunities for care outside of office visits. However, those who might benefit may be unable to or choose not to use these resources, while others might not need them. OBJECTIVE: Electronic Communications and Home Blood Pressure Monitoring (e-BP) was a randomized trial that demonstrated that Web-based pharmacist care led to improved blood pressure (BP) control. During recruitment we attempted to contact all patients with hypertension from 10 clinics to determine whether they were eligible and willing to participate. We wanted to know whether particular subgroups, particularly those from vulnerable populations, were less willing to participate or unable to because they lacked computer access. METHODS: From 2005 to 2006, we sent invitation letters to and attempted to recruit 9298 patients with hypertension. Eligibility to participate in the trial included access to a computer and the Internet, an email address, and uncontrolled BP (BP ≥ 140/90 mmHg). Generalized linear models within a modified Poisson regression framework were used to estimate the relative risk (RR) of ineligibility due to lack of computer access and of having uncontrolled BP. RESULTS: We were able to contact 95.1% (8840/9298) of patients. Those refusing participation (3032/8840, 34.3%) were significantly more likely (P < .05) to be female, be nonwhite, have lower levels of education, and have Medicaid insurance. Among patients who answered survey questions, 22.8% (1673/7354) did not have computer access. Older age, minority race, and lower levels of education were risk factors for lack of computer access, with education as the strongest predictor (RR 2.63, 95% CI 2.30-3.01 for those with a high school degree compared to a college education). Among hypertensive patients with computer access who were willing to participate, African American race (RR 1.22, 95% CI 1.06-1.40), male sex (RR 1.28, 95% CI 1.18-1.38), and obesity (RR 1.53, 95% CI 1.31-1.79) were risk factors for uncontrolled BP. CONCLUSION: Older age, lower socioeconomic status, and lower levels of education were associated with decreased access to and willingness to participate in a Web-based intervention to improve hypertension control. Failure to ameliorate this may worsen health care disparities.

Intractable public health problems are influenced by interacting multi-level factors. Dynamic research approaches in which teams of scientists collaborate beyond traditional disciplinary, institutional, and geographic boundaries have emerged as promising strategies to address pressing public health priorities. However, little prior work has identified, defined, and characterized the outcomes of transdisciplinary (TD) research undertaken to address public health problems. Through a mixed methods approach, we identify, define, and characterize TD outcomes and their relevance to improving population health using the Transdisciplinary Research on Energetics and Cancer (TREC) II initiative as a case example. In Phase I, TREC II leadership (n = 10) identified nine initial TD outcomes. In Phase II (web-based survey; n = 23) and Phase III (interviews; n = 26; and focus groups, n = 23) TREC members defined and characterized each outcome. The resulting nine outcomes are described. The nine complementary TD outcomes can be used as a framework to evaluate progress toward impact on complex public health problems. Strategic investment in infrastructure that supports team development and collaboration, such as a coordination center, cross-center working groups, annual funded developmental projects, and face-to-face meetings, may foster achievement of these outcomes. This exploratory work provides a basis for the future investigation and development of quantitative measurement tools to assess the achievement of TD outcomes that are relevant to solving multifactorial public health problems.
RESUMO
OBJECTIVE: We sought to estimate the direct cost, from the perspective of the health insurer or purchaser, of breast-care services in the year following a false positive screening mammogram compared with a true negative examination. DESIGN: We identified 21,125 women aged 40 to 80 years enrolled in an integrated healthcare delivery system in Washington State, who participated in screening mammography between January 1, 1998 and July 30, 2002. Pathology and cancer registry data were used to identify breast cancer diagnoses in the year following the screening mammogram. A positive examination was defined as a Breast Imaging Reporting and Data System assessment of 0, 4, or 5. Women with a positive screening mammogram but no breast cancer diagnosed within 1 year were classified as false positives. We used diagnostic and procedure codes in automated health plan data to identify services received in the year following the screening mammogram. Medicare reimbursement rates were applied to all services. We used ordinary least-squares linear regression to estimate the difference in costs following a false positive versus true negative screening mammogram. RESULTS: False positive results occurred in 9.9% of women; most false positives (87.3%) were followed by breast imaging only. The mean cost of breast-care following a false positive mammogram was $527. This was $503 (95% confidence interval, $490-$515) more than the cost of breast-care services for true negative women. CONCLUSIONS: The direct costs for breast-related procedures following false positive screening mammograms may contribute substantially to US healthcare spending.

BACKGROUND: Research has documented greater health care costs attributable to intimate partner violence (IPV) among women during and after exposure. However, no studies have determined whether health care costs for abused women return to baseline levels at some point after their abuse ceases. OBJECTIVE: We examine whether health care costs among women exposed to IPV converge with those of non-abused women during a 10-year period following the end of exposure. DESIGN: Retrospective cohort analysis. SETTING: Group Health Cooperative, a large integrated health care system in the Pacific Northwest. PARTICIPANTS: Random sample of English-speaking women aged 18-64 enrolled within Group Health and who participated in a telephone survey between June 2003 and August 2005. MEASUREMENTS: Total health care costs over an 11-year period from January 1, 1992 to December 31, 2002 were compiled using automated health plan data and comparisons made among women exposed to IPV since age 18 and those who never experienced IPV. IPV included physical, sexual, or psychological violence involving an intimate partner, and was assessed using five questions from the Behavioral Risk Factor Surveillance System. RESULTS: Relative to women with no IPV history, total health care costs were significantly higher during IPV exposure, costs that were sustained for 3 years following the end of exposure. By the 4th year following the end of exposure to IPV, health care costs among IPV-exposed women were similar to non-abused women, and this pattern held for the remainder of the 10-year study period. CONCLUSIONS: Policy makers should consider the ongoing needs of victims following abuse exposure. Interventions to reduce the prevalence of IPV or to mitigate the impact of IPV have the potential to reduce the rate of growth of health care costs.

National Institutes of Health consensus and state-of-the science statements are prepared by independent panels of health professionals and public representatives on the basis of 1) the results of a systematic literature review prepared under contract with the Agency for Healthcare Research and Quality (AHRQ); 2) presentations by investigators working in areas relevant to the conference questions during a 2-day public session; 3) questions and statements from conference attendees during open discussion periods that are part of the public session; and 4) closed deliberations by the panel during the remainder of the second day and morning of the third. This statement is an independent report of the panel and is not a policy statement of the National Institutes of Health or the U.S. government. The statement reflects the panel's assessment of medical knowledge available at the time the statement was written. Thus, it provides a "snapshot in time" of the state of knowledge on the conference topic. When reading the statement, keep in mind that new knowledge is inevitably accumulating through medical research.

AIMS: Our goals are 3-fold: (1) to review the leading options for assigning resource coefficients to health services utilization; (2) to discuss the relative advantages of each option; and (3) to provide examples where the research question had marked implications for the choice of which resource measure to employ. METHODS: Three approaches have been used to establish relative resource weights in health services research: (a) direct estimation of production costs through microcosting or step down allocation methods; (b) macrocosting/regression analysis; and (c) standardized resource assignment. We describe each of these methods and provide examples of how the study question drove the choice of resource-use measure. FINDINGS: All empirical resource-intensity weighting systems contain distortions that limit their universal application. Hence, users must select the weighting system that matches the needs of their specific analysis. All systems require significant data resources and data processing. However, inattention to the distortions contained in a complex resource weighting system may undermine the validity and generalizability of an economic evaluation. CONCLUSIONS: Direct estimation of production costs are useful for empirical analyses, but they contain distortions that undermine optimal resource allocation decisions. Researchers must ensure that the data being used meets both the study design and the question being addressed. They also should ensure that the choice of resource measure is the best fit for the analysis. IMPLICATIONS FOR RESEARCH AND POLICY: Researchers should consider which of the available measures is the most appropriate for the question being addressed rather than take "cost " or utilization as a variable over which they have no control.
