Abstract
About 34 million people in the USA have an overactive bladder (OAB), a condition characterized by urinary urgency, with or without urinary incontinence, and usually frequency and nocturia. This condition is associated with increased health risks (e.g. urinary tract infection, falls and fall-related injuries, including broken bones), as well as admission to nursing homes and prolonged hospital stays. The annual costs associated with OAB in the community setting are >9 billion dollars, including 2.9 billion dollars for diagnosis and treatment, 1.5 billion dollars for routine care, 3.9 billion dollars for treatment of health-related consequences, and 841 million dollars in lost productivity. These cost patterns raise the possibility that treating OAB at an early stage may both improve patient care and minimize overall use of healthcare resources. However, before a thorough economic analysis of OAB can be undertaken, more data are needed about the long-term costs and the pathogenesis of OAB-related conditions.

Abstract
Megavoltage CT (MVCT) images of patients are acquired daily on a helical tomotherapy unit (TomoTherapy, Inc., Madison, WI). While these images are used primarily for patient alignment, they can also be used to recalculate the treatment plan for the patient anatomy of the day. The use of MVCT images for dose computations requires a reliable CT number to electron density calibration curve. In this work, we tested the stability of the MVCT numbers by determining the variation of this calibration with spatial arrangement of the phantom, time and MVCT acquisition parameters. The two calibration curves that represent the largest variations were applied to six clinical MVCT images for recalculations to test for dosimetric uncertainties. Among the six cases tested, the largest difference in any of the dosimetric endpoints was 3.1% but more typically the dosimetric endpoints varied by less than 2%. Using an average CT to electron density calibration and a thorax phantom, a series of end-to-end tests were run. Using a rigid phantom, recalculated dose volume histograms (DVHs) were compared with plan DVHs. Using a deformed phantom, recalculated point dose variations were compared with measurements. The MVCT field of view is limited and the image space outside this field of view can be filled in with information from the planning kVCT. This merging technique was tested for a rigid phantom. Finally, the influence of the MVCT slice thickness on the dose recalculation was investigated. The dosimetric differences observed in all phantom tests were within the range of dosimetric uncertainties observed due to variations in the calibration curve. The use of MVCT images allows the assessment of daily dose distributions with an accuracy that is similar to that of the initial kVCT dose calculation.

Abstract
Many chronically ill adults in the United States face high prescription medication costs, yet little is known about the strategies patients adopt to cope with these costs. Through a national survey of 4,055 adults taking prescription medications for one of five chronic diseases, we compared whether respondents cut back on necessities such as food or heat to pay for medications, increased debt, or underused medications because of cost. We also examined the sociodemographic and clinical correlates and differential use by different sub-groups of these three strategies. Overall, 31% of respondents reported pursuing at least one of the strategies over the prior 12 months. Twenty-two percent had cut back on necessities, 16% had increased their debt burden, and 18% had underused prescription drugs. Among patients who underused their medication, 67% also had cut necessities or increased debt. Although we found significant differences in the way patients with varying socio-demographic characteristics responded to medication cost pressures, use of all these strategies was especially common among patients who were low-income, in poor health, and taking multiple medications.

Abstract
BACKGROUND The Internet has emerged as a valuable tool for health information. Half of the U.S. population lacked Internet access in 2001, creating concerns about those without access. Starting in 1999, a survey firm randomly invited individuals to join their research panel in return for free Internet access. This provides a unique setting to study the ways that people who had not previously obtained Internet access use the Internet when it becomes available to them. METHODS In 2001-2002, we surveyed 12,878 individuals 21 years of age and older on the research panel regarding use of the Internet for health; 8935 (69%) responded. We analyzed respondents who had no prior Internet access, and then compared this group to those who had prior Internet access. RESULTS Among those newly provided free Internet access, 24% had used the Internet for health information in the past year, and users reported notable benefits, such as improved knowledge and self-care abilities. Not surprisingly, the no-prior-Internet group reported lower rates of using the Internet (24%) than the group that had obtained Internet access prior to joining the research panel (40%), but the 2 groups reported similar perceptions of the Internet and self-reported effects. CONCLUSIONS Those who obtained Internet access for the first time by joining the panel used the Internet for health and appeared to benefit from it. Access helps explain the digital divide, although most people given free access do not use the Internet for health information.

Abstract
BACKGROUND Although many chronically ill patients underuse prescription medications because of cost concerns, we know little about their discussions with clinicians about this issue. METHODS Nationwide survey of 660 older adults with chronic illnesses who reported underusing medication in the prior year because of cost. We assessed whether patients discussed cost-related medication underuse with clinicians, reasons that some patients did not talk with clinicians about this problem, how clinicians responded when this issue was raised, and how helpful patients perceived clinicians to be. RESULTS Two thirds of respondents never told a clinician in advance that they planned to underuse medication because of the cost, and 35% never discussed the issue at all. Of those who did not tell a clinician, 66% reported that nobody asked them about their ability to pay for prescriptions and 58% reported that they did not think providers could help them. When patients talked with clinicians about medication costs, 72% found those conversations helpful. However, 31% reported that their medications were never changed to a generic or less expensive alternative, and few patients were given other forms of assistance such as information about programs that help pay drug costs (30%) or where to purchase less expensive medication (28%). Patients were most likely to find clinicians helpful if clinicians provided free samples, asked about problems paying for prescriptions, and offered advice about how to pay for patients' current regimens. CONCLUSIONS About one third of chronically ill adults who underuse prescription medication because of the cost never talk with clinicians in advance, and many never raise this issue at all. Clinicians should take a more proactive role in identifying and assisting patients who have problems paying for prescription drugs.

Abstract
OBJECTIVE To learn how age and chronic illness affect costs in the Veterans Affairs healthcare system. STUDY DESIGN Veterans Affairs patients 65 years or older were identified from administrative data. We noted their healthcare utilization, cost, and diagnosis of any of 29 common chronic conditions (CCs). We examined how those 80 years or older differed from the younger patients. RESULTS The Department of Veterans Affairs spent dollars 8.5 billion to treat 1.6 million older patients in fiscal year 2000. Age was less important than chronic illness in explaining cost differences. The oldest patients incurred a mean of dollars 1295 greater costs than the younger patients, primarily because they were more likely to have a high-cost CC. The oldest patients incurred higher total costs than the younger patients in only 14 of 29 groups defined by CC. Long-term care accounted for most of the extra cost of the oldest patients. When this cost was excluded, the oldest patients incurred only dollars 266 more cost than the younger patients. CONCLUSIONS Growth in the population of the oldest patients will increase the number of individuals with CCs requiring long-term care. With its limited long-term care benefit, Medicare will avoid much of this financial consequence. In contrast, the financial risk of acute and long-term care gives the Department of Veterans Affairs an incentive to develop strategies to prevent CCs associated with long-term care.

Abstract
Behavioral health interventions are often gauged with a dichotomous outcome, "success" or "failure." Hidden by this dichotomy is a series of behavior changes that can be followed with the Transtheoretical Model (stages of change). There has been little consideration, however, about whether this information can and should be used in cost-effectiveness analysis. We review the stages of change model and its applications to behavioral health interventions. We then discuss analytical methods for including stages of change, or similar behavior change models, in cost-effectiveness analysis (CEA). This is typically not done but it may be critical for study design and for interpreting CEA results.

Abstract
OBJECTIVES We sought information about the cost-related underuse of medications-which medications are underused, by whom, and how often. METHODS Chronically ill adults were asked to identify how often they underused prescription medication for 16 health conditions because of the cost. RESULTS Eighteen percent of respondents cut back on medication use owing to cost in the previous year, and 14% used less medication at least monthly. Although rates of underuse varied substantially across treatments, prescription coverage and out-of-pocket costs were determinants of underuse across medication types. CONCLUSIONS Many chronically ill adults frequently cut back on medications owing to cost. Patients are selective about the treatments they forgo. Out-of-pocket costs and inadequate prescription coverage may lead to adherence problems for many important medication types.

Abstract
INTRODUCTION Chronic conditions are among the leading causes of death and disability in the United States. The Internet is a source of health information and advice for individuals with chronic conditions and shows promise for helping individuals manage their conditions and improve their quality of life. METHODS We assessed Internet use for health information by people who had one or more of five common chronic conditions. We conducted a national survey of adults aged 21 and older, then analyzed data from 1980 respondents who had Internet access and who reported that they had hypertension, diabetes, cancer, heart problems, and/or depression. RESULTS Adjusted rates for any Internet use for health information ranged from 33.8% (heart problems only) to 52.0% (diabetes only). A sizable minority of respondents - particularly individuals with diabetes - reported that the Internet helped them to manage their condition themselves, and 7.9% said information on the Internet led them to seek care from a different doctor. CONCLUSION Use of the Internet for health information by chronically ill patients is moderate. Self-reported effects on choice of treatment or provider are small but noteworthy.

Abstract
OBJECTIVES We examined consumers' search for information about health insurance choices and their use of the Internet for that search and to manage health benefits. STUDY DESIGN We surveyed a random sample of more than 4500 individuals aged 21 years and older who were members of a survey research panel during December 2001 and January 2002. METHODS The survey included questions about searching for health insurance information in 3 health insurance markets: Medicare, individual or nongroup, and employer-sponsored group. We also asked questions about use of the Internet to manage health benefits. We tabulated means of responses to each question by market and tested for independence across demographic groups using the Pearson chi-square test. RESULTS We identified important differences across and within markets in the extent to which people look for information about health insurance alternatives and the role of the Internet in their search. Although many individuals were unaware of whether their employer or health plan provided a website to manage health benefits, those who used the sites generally evaluated them favorably. CONCLUSIONS Our results suggest that the Internet is an important source of health insurance information, particularly for individuals purchasing coverage individually in the nongroup and Medicare markets relative to those obtaining coverage from an employer. In the case of Medicare coverage, studies focusing on beneficiaries' use of Internet resources may underestimate the Internet's importance by neglecting caregivers who use the Internet. Many individuals may be unaware of the valuable resources available through employers or health plans.

Abstract
BACKGROUND Research with human subjects is essential for most clinical and social science research. As such, the ethical treatment of subjects, including the role of Institutional Review Boards (IRBs), is of paramount concern. The prevailing system of IRBs in the United States reflects an integrated approach in which research organizations have their own local IRB. Recent regulatory changes and a few high-profile problems have prompted proposals for greater investments in IRBs. OBJECTIVES We conducted regression analyses, looking at how IRB size was associated with IRB costs (economies of scale). RESEARCH DESIGN We studied data from a cross-sectional survey. SUBJECTS We studied IRBs at Veterans Affairs (VA) and VA-affiliated medical centers (n = 109); 81 (73%) IRB administrators completed the survey. Fourteen of the administrators had missing data and were excluded from final analysis, leaving a sample of 67. MEASURES The primary dependent variable was IRB costs in 2001, which we estimated from the survey. Independent variables included IRB size measured as the number of actions (ie, number of initial reviews, amendments, continuing/annual reviews, and harms/adverse event reports) reviewed by the IRB in the last year. RESULTS The results indicate that very large economies of scale exist, especially for IRBs that handle fewer than 150 actions per year. CONCLUSIONS A discussion of the costs of benefits of having 3000 to 5000 local IRBs in the United States is warranted because other organizational arrangements could be economically and socially advantageous.

Abstract
PURPOSE Little is known about whether health care providers are effectively identifying patients who have difficulty covering the costs of out-of-pocket prescription medications. We examined whether and how providers are identifying chronically ill adults who have potential problems paying for prescription medications. METHODS We conducted a cross-sectional survey of a national sample of 4050 adults aged 50 years or older who use prescription medications for at least one of five chronic health conditions. The primary outcome measure was patient report of being asked by a doctor or nurse in the prior 12 months whether the patient could afford the prescribed medication. The measures of prescription cost burden were cost-related underuse of medications, cutting back on other necessities to pay for medications, and worries about medication costs. We adjusted for patient income, education, race/ethnicity, age, sex, health status, number of prescribed medications, pharmacy benefits, frequency of outpatient visits, having a regular health care provider, and sampling weights. RESULTS In the weighted analyses, 16% (547/4050) of respondents reported that they had been asked about potential problems paying for a prescribed medication. Only 360 (24%) of the 1499 respondents who reported one or more burdens from out-of-pocket medication costs reported being asked this question. After adjusting for potential confounders, patients who had cut back on medication use or other necessities to cover payments were no more likely than other patients to be asked about the ability to pay for prescription medications. Concerns about medication costs, being a racial/ethnic minority, taking seven or more prescription medications, and having no prescription coverage were independently associated with a greater likelihood of being asked about possible problems with prescription costs. CONCLUSION Few chronically ill patients who are at risk of or experiencing problems related to prescription medication costs report that their clinicians had asked them about possible medication payment difficulties.

Abstract
BACKGROUND Chronically ill patients often experience difficulty paying for their medications and, as a result, use less than prescribed. OBJECTIVES The objectives of this study were to determine the relationship between patients with diabetes' health insurance coverage and cost-related medication underuse, the association between cost-related underuse and health outcomes, and the role of comorbidity in this process. RESEARCH DESIGN We used a patient survey with linkage to insurance information and hemoglobin A1C (A1C) test results. PATIENTS We studied 766 adults with diabetes recruited from 3 Veterans Affairs (VA), 1 county, and 1 university healthcare system. MAIN OUTCOMES Main outcomes consisted of self-reported medication underuse as a result of cost, A1C levels, symptom burden, and Medical Outcomes Study 12-Item Short-Form physical and mental functioning scores. RESULTS Fewer VA patients reported cost-related medication underuse (9%) than patients with private insurance (18%), Medicare (25%), Medicaid (31%), or no health insurance (40%; P <0.0001). Underuse was substantially more common among patients with multiple comorbid chronic illnesses, except those who used VA care. The risk of cost-related underuse for patients with 3+ comorbidities was 2.8 times as high among privately insured patients as VA patients (95% confidence interval, 1.2-6.5), and 4.3 to 8.3 times as high among patients with Medicare, Medicaid, or no insurance. Individuals reporting cost-related medication underuse had A1C levels that were substantially higher than other patients (P <0.0001), more symptoms, and poorer physical and mental functioning (all P <0.05). CONCLUSIONS Many patients with diabetes use less of their medication than prescribed because of the cost, and those reporting cost-related adherence problems have poorer health. Cost-related adherence problems are especially common among patients with diabetes with comorbid diseases, although the VA's drug coverage may protect patients from this increased risk.

Abstract
OBJECTIVES To update the cost of urinary incontinence (UI) for year 2000 and compare it with the cost of overactive bladder (OAB). METHODS Using the cost-of-illness framework, disease epidemiologic data were combined with treatment rates, consequence probabilities, and average cost estimates. All costs reflect the costs during 2000. RESULTS The total cost of UI and OAB was 19.5 billion dollars and 12.6 billion dollars, respectively (year 2000 dollars). With UI, 14.2 billion dollars was borne by community residents and 5.3 billion dollars by institutional residents. With OAB, 9.1 and 3.5 billion dollars, respectively, was incurred by community and institutional residents. CONCLUSIONS OAB affected 34 million individuals compared with 17 million with UI. Despite the differences in epidemiology, the total and per-person costs of UI were higher than the OAB costs because OAB individuals without incontinent episodes incurred fewer costs, on average.

Abstract
OBJECTIVE To identify problems faced by older adults with diabetes due to out-of-pocket medication costs. RESEARCH DESIGN AND METHODS In this cross-sectional national survey of 875 adults with diabetes treated with hypoglycemic medication, respondents reported whether they had underused prescription medications due to cost pressures or had experienced other financial problems associated with medication costs such as forgoing basic necessities. Respondents also described their interactions with clinicians about medication costs. RESULTS A total of 19% of respondents reported cutting back on medication use in the prior year due to cost, 11% reported cutting back on their diabetes medications, and 7% reported cutting back on their diabetes medications at least once per month. Moreover, 28% reported forgoing food or other essentials to pay medication costs, 14% increased their credit card debt, and 10% borrowed money from family or friends to pay for their prescriptions. Medication cost problems were especially common among respondents who were younger, had higher monthly out-of-pocket costs, and had no prescription drug coverage. In general, few respondents, including those reporting medication cost problems, reported that their health care providers had given them information or other assistance to address medication cost pressures. CONCLUSIONS Out-of-pocket medication costs pose a significant burden to many adults with diabetes and contribute to decreased treatment adherence. Clinicians should actively identify patients with diabetes who are facing medication cost pressures and assist them by modifying their medication regimens, helping them understand the importance of each prescribed medication, providing information on sources of low-cost drugs, and linking patients with coverage programs.

Abstract
The mid-1990s saw dramatic changes in mental health care in the Department of Veterans Affairs (VA), the largest provider of such care in the United States. Spending for specialized inpatient mental health care fell 21 percent from 1995 to 2001, while spending for specialized outpatient care rose 63 percent. The shift from inpatient to outpatient care was accompanied by rapid increases in outpatient medication costs. Overall, the VA reduced the average cost (per VA user) of specialized mental health care by 22 percent while it increased the number of users of these services by 35 percent.

Abstract
OBJECTIVES To estimate the economic costs of overactive bladder (OAB), including community and nursing home residents, and to compare the costs in male versus female and older versus younger populations. METHODS The National Overactive Bladder Evaluation Program included a representative telephone survey of 5204 community-dwelling adults 18 years and older in the United States and a follow-up postal survey of all individuals with OAB identified and age and sex-matched controls. The postal survey asked respondents about bladder symptoms, self-care use, treatment use, work loss, and OAB-related health consequences. Survey data estimates were combined with year 2000 average cost data to calculate the cost of OAB in the community. Institutional costs were estimated from the costs of urinary incontinence in nursing homes, limited to only those with urge incontinence or mixed incontinence (urge and stress). RESULTS The estimated total economic cost of OAB was 12.02 billion dollars in 2000, with 9.17 and 2.85 billion dollars incurred in the community and institutions, respectively. Community female and male OAB costs totaled 7.37 and 1.79 billion dollars, respectively. The estimated total cost was sensitive to the estimated prevalence of OAB; therefore, we calculated the average cost per community-dwelling person with OAB, which was 267 dollars per year. CONCLUSIONS By quantifying the total economic costs of OAB, this study-the first obtained from national survey data-provides an important perspective of this condition in society. The conservative estimates of the total cost of OAB were comparable to those of osteoporosis and gynecologic and breast cancer. Although this provides information on the direct and indirect costs of OAB, quality-of-life issues must be taken into account to gain a better understanding of this condition.

This study estimated the costs for operating high-volume and low-volume IRBs. METHOD IRB costs were calculated from published summary data. Costs were standardized to reflect 2001 dollars. RESULTS Total estimated costs for operating high-volume and low-volume IRBs were $770,674 and $76,626, respectively. The average cost per action, a measure of economic efficiency, was lower for high-volume IRBs ($277 per action) than it was for low-volume IRBs ($799 per action). CONCLUSIONS Although high-volume IRBs are more expensive than are low-volume IRBs in absolute terms, they are more economically efficient. Policy debates should consider the potential savings from large IRBs, perhaps by encouraging small IRBs to merge, although this may result in less local review, control, and oversight.

Abstract
PURPOSE Given stereotypes of older adults, there is the perception that older adults will not use health information technologies. One concern is that practitioners might shy away from providing older patients with health information, and in particular, computerized information. The study's primary objective was to evaluate whether a health information intervention had a differential effect for people of different ages. DESIGN AND METHODS Quasi-experimental survey data from an assessment of a communitywide informational intervention were used. People were asked about their use of medical reference books, telephone advice nurses, or computers for health information in the past few months. In total, 5,909 surveys were completed. RESULTS The data show that older adults were no less likely (and were sometimes more likely) to use health information as a result of the intervention than younger adults. For telephone advice nurses and computers, the effect of the intervention was not significantly different for the different age groups. Yet, compared with persons 18-29 years of age, those over the age of 65 had a 17-percentage point increase in using a self-care book. IMPLICATIONS We find convincing evidence to counter the stereotype that older adults are resistant to trying new health information technologies.

Abstract
CONTEXT The Internet has attracted considerable attention as a means to improve health and health care delivery, but it is not clear how prevalent Internet use for health care really is or what impact it has on health care utilization. Available estimates of use and impact vary widely. Without accurate estimates of use and effects, it is difficult to focus policy discussions or design appropriate policy activities. OBJECTIVES To measure the extent of Internet use for health care among a representative sample of the US population, to examine the prevalence of e-mail use for health care, and to examine the effects that Internet and e-mail use has on users' knowledge about health care matters and their use of the health care system. DESIGN, SETTING, AND PARTICIPANTS Survey conducted in December 2001 and January 2002 among a sample drawn from a research panel of more than 60 000 US households developed and maintained by Knowledge Networks. Responses were analyzed from 4764 individuals aged 21 years or older who were self-reported Internet users. MAIN OUTCOME MEASURES Self-reported rates in the past year of Internet and e-mail use to obtain information related to health, contact health care professionals, and obtain prescriptions; perceived effects of Internet and e-mail use on health care use. RESULTS Approximately 40% of respondents with Internet access reported using the Internet to look for advice or information about health or health care in 2001. Six percent reported using e-mail to contact a physician or other health care professional. About one third of those using the Internet for health reported that using the Internet affected a decision about health or their health care, but very few reported impacts on measurable health care utilization; 94% said that Internet use had no effect on the number of physician visits they had and 93% said it had no effect on the number of telephone contacts. Five percent or less reported use of the Internet to obtain prescriptions or purchase pharmaceutical products. CONCLUSIONS Although many people use the Internet for health information, use is not as common as is sometimes reported. Effects on actual health care utilization are also less substantial than some have claimed. Discussions of the role of the Internet in health care and the development of policies that might influence this role should not presume that use of the Internet for health information is universal or that the Internet strongly influences health care utilization.
