Hunter and New England HealthPathways: a 4-year journey of integrated care.

Objective This paper describes the 4-year journey of Hunter and New England HealthPathways - a password-protected web-based portal designed to provide localised evidence-informed clinical and referral information to support general practice at the point of care. Methods A process evaluation was conducted in 2013, with a case study comparison performed in 2014 to assess impact of HealthPathways on patient referral and access to specialist care, followed by a review in 2016 of utilisation of the online portal to assess whether healthcare providers continued to access HealthPathways. Results Increased utilisation was correlated with an increase in the number of pathways published online. Clinical leadership and the process of developing pathways built relationships between primary care and specialist teams. Case studies indicated that a comprehensive approach to pathway implementation accompanied by service redesign resulted in higher pathway use and improved access to specialist care. Senior management support and a formal partnership between major health care providers led to strong governance of HealthPathways and the delivery of other integrated care initiatives. There was significant growth in utilisation over the 4 years, increasing to an average of 6679 sessions per month in 2016 and more general practices reported use of HealthPathways. Conclusions HealthPathways is a vehicle for building strong foundations to support system change and integrated care. The critical elements for acceptability, growth and sustainability are the strong relationships between primary care and specialist clinicians, as well as formal partnerships that are built from the processes used to develop HealthPathways. What is known about the topic? HealthPathways and similar web-based evidence-informed guidelines aimed at improving system integration are increasing in Australia. There are few published papers that describe approaches to inform the ongoing implementation of such programs. What does this paper add? This paper describes iterative methodology for evaluating complex programs, such as HealthPathways, that identifies the critical factors required to build sustainable models of integrated care. What are the implications for practitioners? The 4-year experience of Hunter and New England HealthPathways provides an approach to improve the implementation, sustainability and spread of similar programs and associated integrated care initiatives.

Disparities in cancer mortality and incidence among American Indians and Alaska Natives in the United States.

OBJECTIVES: We used improved data on American Indian and Alaska Native (AI/AN) ancestry to provide an updated and comprehensive description of cancer mortality and incidence among AI/AN populations from 1990 to 2009. METHODS: We linked the National Death Index and central cancer registry records independently to the Indian Health Service (IHS) patient registration database to improve identification of AI/AN persons in cancer mortality and incidence data, respectively. Analyses were restricted to non-Hispanic persons residing in Contract Health Service Delivery Area counties in 6 geographic regions of the United States. We compared age-adjusted mortality and incidence rates for AI/AN populations with White populations using rate ratios and mortality-to-incidence ratios. Trends were described using joinpoint analysis. RESULTS: Cancer mortality and incidence rates for AI/AN persons compared with Whites varied by region and type of cancer. Trends in death rates showed that greater progress in cancer control was achieved for White populations compared with AI/AN populations over the last 2 decades. CONCLUSIONS: Spatial variations in mortality and incidence by type of cancer demonstrated both persistent and emerging challenges for cancer control in AI/AN populations.

Data and trends in cancer screening in the United States: results from the 2005 National Health Interview Survey.

BACKGROUND: This paper examines the prevalence of cancer screening use as reported in 2005 among US adults, focusing on differences among historically underserved subgroups. We also examine trends from 1992 through 2005 to determine whether differences in screening use are increasing, staying the same, or decreasing. METHODS: Data from the National Health Interview Surveys between 1992 and 2005 were analyzed to describe patterns and trends in cancer screening practices, including Papanicolaou test, mammography, prostate-specific antigen, and colorectal screening. Logistic regression was used to report 2005 data for population subgroups defined by several demographic and socioeconomic characteristics. RESULTS: Rates of use for cancer tests are rising only for colorectal cancer, due largely to the increase in colorectal endoscopy screening. Use of all the modalities was strongly influenced by contact with a physician and by having health insurance coverage. CONCLUSIONS: There remain large gaps in use for all screening modalities by education, income, usual source of care, health insurance, and recent physician contact. These specific populations would benefit from interventions to overcome these barriers to screening.

Using the National Health Interview Survey to understand and address the impact of tobacco in the United States: past perspectives and future considerations.

OBJECTIVE: The National Health Interview Survey (NHIS) is a continuous, nationwide, household interview survey of the civilian noninstitutionalized population of the United States. This annual survey is conducted by the National Center for Health Statistics, part of the Centers for Disease Control and Prevention. Since 1965, the survey and its supplements have provided data on issues related to the use of cigarettes and other tobacco products. This paper describes the survey, provides an overview of peer-reviewed and government-issued research that uses tobacco-related data from the NHIS, and suggests additional areas for exploration and directions for future research. DATA SOURCES: We performed literature searches using the PubMed database, selecting articles from 1966 to 2008. Study selection. Inclusion criteria were relevancy to tobacco research and primary use of NHIS data; 117 articles met these criteria. Data extraction and synthesis. Tobacco-related data from the NHIS have been used to analyze smoking prevalence and trends; attitudes, knowledge, and beliefs; initiation; cessation and advice to quit; health care practices; health consequences; secondhand smoke exposure; and use of smokeless tobacco. To date, use of these data has had broad application; however, great potential still exists for additional use. CONCLUSION: NHIS data provide information that can be useful to both practitioners and researchers. It is important to explore new and creative ways to best use these data and to address the full range of salient tobacco-related topics. Doing so will better inform future tobacco control research and programs.

Cancer among American Indians and Alaska Natives in the United States, 1999-2004.

BACKGROUND: Cancer incidence rates vary among American Indian and Alaska Native (AI/AN) populations and often differ from rates among non-Hispanic whites (NHWs). However, the misclassification of race for AI/AN cancer cases in central cancer registries may have led to underestimates of the AI/AN cancer burden in previous reports. METHODS: Cases diagnosed during 1999 through 2004 were identified from population-based cancer registries in the United States. Age-adjusted rates were calculated for the 25 most common sites for AI/ANs and NHWs. To minimize the misclassification of race, cancer registry records were linked with patient registration files from the Indian Health Service (IHS). Analyses were restricted to Contract Health Service Delivery Area (CHSDA) counties and were stratified by IHS region. RESULTS: In CHSDA counties, cancer incidence rates among AI/ANs varied widely by region, whereas rates among NHWs did not. For all cancer sites combined, AI/AN rates were higher than NHW rates among both males and females in the Northern and Southern Plains, and among Alaska Native Females; AI/AN rates were lower than NHW rates in the Southwest, the Pacific Coast, and the East. Lung cancer and colorectal cancer rates for AI/ANs exceeded rates for NHWs in Alaska and the Northern Plains. Rates for stomach, gallbladder, kidney, and liver cancer were higher among AI/ANs than among NHWs overall, in Alaska, in the Plains regions, and in the Southwest. CONCLUSIONS: Regional differences in cancer incidence rates among AI/AN populations were not obvious from nationwide data and highlighted opportunities for cancer control and prevention. It is unlikely that such differences are explained by race misclassification.

Gallbladder cancer incidence among American Indians and Alaska Natives, US, 1999-2004.

BACKGROUND: Gallbladder cancer (GBC) is rare; however, it disproportionately affects the American Indian and Alaska Natives (AI/AN) population. The purpose of the study was to characterize GBC among AI/AN in the US population. METHODS: Cases of GBC diagnosed between 1999 and 2004 and collected by state-based cancer registries were included. Registry records were linked with Indian Health Service (IHS) administration records to decrease race misclassification of AI/AN. GBC rates and/or percent distributions for AI/AN and non-Hispanic whites (NHW) were calculated by sex, IHS region, age, and stage for all US counties and IHS Contract Health Service Delivery Area (CHSDA) counties, in which approximately 56% of US AI/AN individuals reside. RESULTS: In CHSDA counties, the GBC incidence rate among AI/AN was 3.3 per 100,000, which was significantly higher than that among NHW (P < .05). Rates varied widely among IHS regions and ranged from 1.5 in the East to 5.5 in Alaska. Rates were higher among AI/AN females than males in all regions, except the Northern Plains. Higher percentages of GBC were diagnosed among AI/AN aged <65 years compared with NHW. GBC was most often diagnosed at the regional stage among AI/AN, whereas GBC was most often diagnosed at regional or distant stages among NHW. CONCLUSIONS: To the authors' knowledge to date, this is the most comprehensive study of GBC incidence among AI/AN in the US. The accurate characterization of GBC in this population could help inform the development of interventions aimed at reducing morbidity and mortality from this disease.

Breast cancer incidence among American Indian and Alaska Native women: US, 1999-2004.

BACKGROUND: Breast cancer is a leading cause of cancer morbidity and mortality among American Indian and Alaska Native (AI/AN) women. Although published studies have suggested that breast cancer rates among AI/AN women are lower than those among other racial and ethnic populations, accurate determinations of the breast cancer burden have been hampered by misclassification of AI/AN race. METHODS: Cancer incidence data from the National Program of Cancer Registries and the Surveillance, Epidemiology, and End Results Program were combined to estimate age-adjusted rates for the diagnosis years 1999 through 2004. Several steps were taken to reduce the misclassification of AI/AN race: linking cases to Indian Health Service (IHS) patient services database, restricting analyses to Contract Health Service Delivery Area counties, and stratifying results by IHS region. RESULTS: Breast cancer incidence rates among AI/AN women varied nearly 3-fold across IHS regions. The highest rates were in Alaska (134.8) and the Plains (Northern, 115.9; Southern, 115.7), and the lowest rates were in the Southwest (50.8). The rate in Alaska was similar to the rate among non-Hispanic white (NHW) women in Alaska. Overall, AI/AN women had lower rates of breast cancer than NHW women, but AI/AN women were more likely to be diagnosed with late-stage disease. CONCLUSIONS: To the authors' knowledge, this report provides the most comprehensive breast cancer incidence data for AI/AN women to date. The wide regional variation indicates an important need for etiologic and health services research, and the large percentage of AI/AN women with late-stage disease demands innovative approaches for increasing access to screening.

Concordance and discordance between primary and secondary care health workers in perceptions of barriers to diabetes care.

AIMS: To understand differences between primary care health professionals and secondary care health workers in their perceptions of barriers to good diabetes care. METHODS: Practice nurses and general practitioners in the Waikato region of New Zealand were surveyed to ascertain their perceptions (as primary health care workers) of barriers to diabetes care; 315 replies were received (70% response rate). Secondary care health professionals working at Waikato Hospital were similarly surveyed; 123 replies were received (71% response rate). RESULTS: Primary care health workers are more likely than secondary health care workers to rate motivation, self-belief, financial issues, lack of governmental funding, lack of public awareness of diabetes, and lack of symptoms as barriers to care. Secondary health care workers are significantly more likely to rate appointment systems, inappropriate cultural messages, lack of community-based services, high prevalence of diabetes, and unhelpful health practitioners. CONCLUSIONS: Better understanding of the respective differences in perceptions between primary and secondary care may assist the development of a more functional and unified health system. It is suggested that greater emphasis on individual diabetes education and a stronger focus on motivation and lifestyle changes at both the individual and community levels may improve outcomes.

Annual report to the nation on the status of cancer, 1975-2004, featuring cancer in American Indians and Alaska Natives.

BACKGROUND: The American Cancer Society, the Centers for Disease Control and Prevention, the National Cancer Institute, and the North American Association of Central Cancer Registries collaborate annually to provide updated information on cancer occurrence and trends in the U.S. The 2007 report features a comprehensive compilation of cancer information for American Indians and Alaska Natives (AI/AN). METHODS: Cancer incidence data were available for up to 82% of the U.S. population. Cancer deaths were available for the entire U.S. population. Long-term (1975 through 2004) and fixed-interval (1995 through 2004) incidence and mortality trends were evaluated by annual percent change using regression analyses (2-sided P < .05). Cancer screening, risk factors, socioeconomic characteristics, incidence data, and stage were compiled for non-Hispanic whites (NHW) and AI/AN across 6 regions of the U.S. RESULTS: Overall cancer death rates decreased by 2.1% per year from 2002 through 2004, nearly twice the annual decrease of 1.1% per year from 1993 through 2002. Among men and women, death rates declined for most cancers. Among women, lung cancer incidence rates no longer were increasing and death rates, although they still were increasing slightly, were increasing at a much slower rate than in the past. Breast cancer incidence rates in women decreased 3.5% per year from 2001 to 2004, the first decrease observed in 20 years. Colorectal cancer incidence and death rates and prostate cancer death rates declined, with colorectal cancer death rates dropping more sharply from 2002 through 2004. Overall, rates for AI/AN were lower than for NHW from 1999 through 2004 for most cancers, but they were higher for cancers of the stomach, liver, cervix, kidney, and gallbladder. Regional analyses, however, revealed high rates for AI/AN in the Northern and Southern Plains and Alaska. For cancers of the breast, colon and rectum, prostate, and cervix, AI/AN were less likely than NHW to be diagnosed at localized stages. CONCLUSIONS: For all races/ethnicities combined in the U.S., favorable trends in incidence and mortality were noted for lung and colorectal cancer in men and women and for breast cancer in women. For the AI/AN population, lower overall cancer incidence and death rates obscured important variations by geographic regions and less favorable healthcare access and socioeconomic status. Enhanced tobacco control and cancer screening, especially in the Northern and Southern Plains and Alaska, emerged as clear priorities.

Discordance in perceptions of barriers to diabetes care between patients and primary care and secondary care.

OBJECTIVE: We sought to compare perceived barriers to diabetes care between people with diabetes and different health professional groups. RESEARCH DESIGN AND METHODS: This was a cross-sectional, postal, open-questionnaire survey conducted in the Waikato district, New Zealand. A total of 3,890 individuals with diabetes participated, as well as 436 primary and secondary health professionals. RESULTS: Barriers were reported in 69.7% of patients. Psychological barriers were most important (55.5%), followed by systems barriers (25.7%), and then knowledge as least important (15.3%). Psychological barriers were ranked first among general practitioners (91.0%), but systems barriers were ranked first by other health professionals (38.8-100%). General practitioner and patient barrier group rankings were similar (r(T) = 0.976, P < 0.05). Of specific barriers among individuals with diabetes, strictness of treatment regimen was the most frequently reported (42.3 vs. 0.1-16.8%) (P < 0.001) and 2.5 (95% CI 2.4-2.7)- to 3.4 (3.2-3.7)-fold more than the 2nd through 4th ranked barriers. Motivation was the most common specific barrier reported by general practitioners (86%), practice nurses (31.5%), and the diabetes team (85.7%). Practice and hospital nurse/dietitian rankings were most comparable with patients (r(T) = 0.457 and 0.466, respectively, both P < 0.05). A major area of patient-health professional discordance was the influence of other health problems, which was ranked 2nd among patients but 10th-18th among health professionals. CONCLUSIONS: The most important barriers to diabetes care perceived by patients are psychological and particularly relate to the strictness of the regimen. Discordance between patients and different health professionals exists in the perception of the importance of different barriers to diabetes care.

Investigating the accuracy of ethnicity data in New Zealand hospital records: still room for improvement.

BACKGROUND: The accuracy of ethnicity information in the New Zealand hospital data was reported on in 1994. Data collected in the Barriers to Diabetes Care in the Waikato Study enables further evaluation of the accuracy of ethnicity information in hospital records. AIMS: One aim of public health policy is addressing health disparities between ethnic groups. Monitoring disparities depends on accurate outcome data, such as that from hospitals. It would be expected that this data would improve over time. This paper reports on the contemporary accuracy of ethnicity data in hospital records in the Waikato district. METHODS: Self-identified ethnicity data were gathered as part of the Barriers to Diabetes Care in the Waikato mail survey. Hospital record data were collected for those participants who had consented for access to their hospital records. RESULTS: Complete data was available for 3500 people with diabetes. Ethnicity in the hospital record was correct for one of the sometimes multiple, self-identified ethnicities for 97.7 (95CI 96.8-98.3)% of respondents. Ethnicity data were concordant for 71 (67-75)% of Maori and 99 (99-100)% of non-Maori. The non-Maori ethnic group was disaggregated into component groups: the hospital record agreed with self identified ethnicity for 89 (87-91)% of Europeans, 67 (55-78)% of Pacific groups, 70 (57-81)% of South Asian groups, 64 (48-77)% of Asian groups, and 41 (27-57)% of 'Other' ethnic groups. CONCLUSIONS: Hospital records continue to mis-record ethnicity when compared to a self-identified ethnicity. Mis-recording occurs for all ethnic groups, and is more pronounced at more specific levels of ethnic group. Researchers, clinicians, and policy makers must be cognisant of these continuing discrepancies when using hospital record data to describe ethnic variations in health status, service utilisation, or for policy planning activities.

Cancer screening and risk factor rates among American Indians.

OBJECTIVES: We examined cancer screening and risk factor patterns in California using 4 different statistical tabulations of American Indian and Alaska Native (AIAN) populations. METHODS: We used the 2001 California Health Interview Survey to compare cancer screening and risk factor data across 4 different tabulation approaches. We calculated weighted prevalence estimates by gender and race/ethnicity for cancer screening and risk factors, sociodemographic characteristics, and access to care variables. We compared AIAN men and women with members of other racial groups and examined outcomes among AIAN men and women using the 4 tabulation methods. RESULTS: Although some differences were small, in general, screening and risk factor rates among American Indians/Alaska Natives were most similar to rates among Whites when the most inclusive multiracial tabulation approach was used and least similar when the more exclusive US census "single-race" approach was used. CONCLUSIONS: Racial misclassification and undercounting are among the most difficult obstacles to obtaining accurate and informative data on the AIAN population. Our analysis suggests some guidelines for overcoming these obstacles.

Review of the Australian incident monitoring system.

BACKGROUND: A survey was conducted to assess the benefits and limitations of the Australian Incident Monitoring System (AIMS) as a programme to improve patient safety. METHODS: A 12-point questionnaire was sent to 12 current users of AIMS in November 2002. RESULTS: The AIMS provides a consistent system of coding, trending and monitoring of incident data. It promotes a patient safety culture and an awareness of system error. Other benefits include the building of teamwork and the implementation of strategies to reduce the prevalence and severity of incidents. The majority of respondents (83%) reported that AIMS investigations resulted in significant changes to equipment usage, medication prescribing or administration, clinical protocols, training programmes and falls risk assessment tools. Although 75% of users reported improvements in patient outcomes, these were difficult to measure. A major limitation of AIMS was the low rate of incident reporting by medical staff. Voluntary reporting systems did not capture all incident data and the information was often too generic for root cause analysis. There were difficulties benchmarking data and concerns were raised regarding the ownership of information. The programme requires ongoing resources to implement change strategies and to maintain incident reporting levels. On a scale of 1 (poor rating) to 10 (excellent rating) the mean benefit rating was 7.6. CONCLUSION: The Australian Incident Monitoring System is beneficial as a component of a clinical risk management strategy. Usefulness could be improved by increased participation by medical staff. The level of resources required should not be underestimated if the programme is to demonstrate improvements to patient outcomes. More recent versions of AIMS promise improved capabilities and will require similar evaluation.

Skin antiseptics and the risk of operating theatre fires.

BACKGROUND: Following press reports of patients catching fire or receiving chemical burns in the operating theatre, a review was conducted on the flammability of skin antiseptics. The purpose of the paper was to clarify confusion regarding povidine-iodine (Betadine), which had been reported as being flammable, and also to determine the use of alcohol-based solutions in the Hunter Area Health Service. A risk assessment was conducted and risk reduction strategies outlined. METHODS: Risk assessment was made following a literature review and an audit of 10 operating theatres in the Hunter Area Health Service. RESULTS: Risk for operating room fires from alcohol-based skin antiseptics was confirmed. Antiseptics in aqueous solutions only smoulder. The Hunter Health survey indicated that although alcohol-based solutions were not used in operating theatres, they were used in anaesthetic bays for insertion of epidural and central line catheters. Strategies to reduce the risk of fire include discontinuation of use of alcohol-based skin antiseptics in operating theatres; using fire retardant surgical drapes; installing over-current protection devices on electrical equipment; minimizing flammable conditions by avoiding nitrous oxide and using the lowest required concentration of inspired oxygen; use of non-flammable cuffed endotracheal tubes; education and training of operating theatre personnel in fire hazards. CONCLUSIONS: Operating theatre fires continue to be a major risk for patient safety. In order to reduce this risk, the strategies outlined here should be followed.

Elective open abdominal aortic aneurysm repair: a seven-year experience.

INTRODUCTION: The seven-year experience of elective abdominal aortic aneurysm (AAA) repair of a vascular surgical unit in a teaching hospital was reviewed to determine the factors associated with in-hospital mortality. METHODS: All patients who underwent elective open repair of an AAA between July 1, 1991, and June 30, 1998, were identified using International Classification of Diseases Ninth Revision (ICD-9) codes. Twenty-four variables were selected for investigation by reviewing the published literature and by discussion with local vascular surgeons. Data were obtained by retrospective medical record review. Variables were first analysed by univariate analysis, and those with a p-value up to 0.25 were included in multivariate analysis. RESULTS: Of the 219 patients reviewed, 8 (3.7%, 95% confidence interval, 1.6%, 7.1%) died during the admission. The mean age of patients was 69.9 years, and 81% of them were male. Univariate analysis found that female sex, renal artery involvement in the aneurysm, and aortic cross-clamp duration of 90 min or greater were significantly associated with mortality. Multivariate analysis found that female sex, use of a bifurcated graft, and performance of an additional procedure at the time of operation were the only variables independently associated with mortality. DISCUSSION: Use of a bifurcated graft was a significant prognostic variable on logistic regression analysis confirming that the technical difficulty of the operation and the morphology of the aneurysm are important factors in determining mortality. Why women may be at higher risk for death is unclear. This study also highlights that caution is required when interpreting raw audit data.

Measuring clinical audit and peer review practice in a diverse health care setting.

BACKGROUND: A measurement system was devised to determine the extent of clinical audit and peer review across the Hunter Area Health Service, to compare changes over time and to assess the effect of the implementation of a policy on the conduct of patient safety meetings. METHODS: Two surveys were conducted over consecutive years (2001, 2002). A scoring system was developed based on a 12 point questionnaire. Ten points were given for a 'yes' response and zero for a 'no' response. Points were also given for frequency of meetings. Statistical analysis was by the Mann-Whitney U-test. The questionnaire included items on clinical indicators, management of issues arising and whether meetings are multidisciplinary, chaired and points for action minuted and followed up. RESULTS: One-hundred and five units provided data for the 2001 survey (100% response rate) and 109 units provided data for the 2002 survey (100% response rate). There was a significant increase in the median score in the 2002 survey (median 101; interquartile range 72-113) when compared with the 2001 Survey (median 91; interquartile range 51-110; P = 0.016). There was an improvement of 9% in units scoring in the highest quartile (90-120 points) and a decrease of 5% in units scoring in the lowest quartile (0-29 points). CONCLUSIONS: This methodology allows for the quantitative measurement of audit and peer review activities across clinical units. It might assist clinicians, professional colleges and departments of health in the further development of the recertification\revalidation process.

Cancer rates among American Indians and Alaska Natives: is there a national perspective.

BACKGROUND: Two important goals of cancer surveillance are to provide milestones in the effort to reduce the cancer burden and to generate observations that form the basis for cancer research and intervention for cancer prevention and control. Determination of the cancer burden among American Indians and Alaska Natives (AIAN) has been difficult largely due to lack of data collection efforts in many areas of the country and misclassification of racial data that results in undercounting of Native Americans. There is a revitalized commitment to improve data collection among the national agencies and organizations. METHODS: Data on cancer trends from 12 areas covered by the Surveillance, Epidemiology and End Results (SEER) Program were reviewed for incidence and death rates for 1992-2000. AIAN trends were examined and compared with trends among other racial/ethnic population groups. Reference was made to studies of disease-specific survival for nine of the SEER areas for 1988-1997. RESULTS: In SEER areas, cancer incidence rates for AIAN populations appeared to be decreasing significantly for lung and breast cancers among women and for prostate cancer among men. However, death rates rose, although not significantly, over the same period, except for a significant decrease in prostate cancer. Among the cancers with rising death rates were lung cancer (AIAN women) and colorectal cancer (AIAN men). In addition, survival often was lower for AIAN populations. CONCLUSIONS: Although the incidence was stable or decreased among AIAN populations, increased death rates and lower survival rates indicate the need for intensified application of cancer prevention and control measures, including screening and treatment. Difficulties in interpretation of data include small population size and substantial interregional differences in rates.

Progress in cancer screening practices in the United States: results from the 2000 National Health Interview Survey.

BACKGROUND: Understanding differences in cancer screening among population groups in 2000 and successes or failures in reducing disparities over time among groups is important for planning a public health strategy to reduce or eliminate health disparities, a major goal of Healthy People 2010 national cancer screening objectives. In 2000, the new cancer control module added to the National Health Interview Survey (NHIS) collected more detailed information on cancer screening compared with previous surveys. METHODS: Data from the 2000 NHIS and earlier surveys were analyzed to discern patterns and trends in cancer screening practices, including Pap tests, mammography, prostate specific antigen (PSA) screening, and colorectal screening. The data are reported for population subgroups that were defined by a number of demographic and socioeconomic characteristics. RESULTS: Women who were least likely to have had a mammogram within the last 2 years were those with no usual source of health care (61%), women with no health insurance (67%), and women who immigrated to the United States within the last 10 years (61%). Results for Pap tests within the last 3 years were similar. Among both men and women, those least likely to have had a fecal occult blood test or endoscopy within the recommended screening interval had no usual source of care (14% for men and 18% for women), no health insurance (20% for men and 18% for women), or were recent immigrants (20% for men and 18% for women). An analysis of changes in test use since the 1987 survey indicates that the disparities are widening among groups with no usual source of care. CONCLUSIONS: No striking improvements have been observed for the groups with greatest need. Although screening use for most groups has increased since 1987, major disparities remain. Some groups, notably individuals with no usual source of care and the uninsured are falling further behind; and, according to the 2000 data, recent immigrants also experience a significant gap in screening utilization. More attention is needed to overcome screening barriers for these groups if the population benefits of cancer screening are to be achieved.

Cancer screening practices from National Health Interview Surveys: past, present, and future.

The National Health Interview Survey (NHIS) has provided data about health behaviors at the national level since 1957. The 1987 and 1992 Cancer Control Supplements to the NHIS, along with other supplemental surveys administered intermittently on self-reported cancer-related behaviors, have contributed to important research and public health purposes. In this article, we reviewed 73 papers published between 1980 and 2001 that used NHIS data, including the first report from the 1998 NHIS, to examine what has been learned from past surveys. Our goal was to facilitate future analyses of recently released data on cancer screening practices from the Cancer Control Supplement to the 2000 NHIS, which is now known as the Cancer Control Module. We categorized the papers according to which of the following three study approaches they used: trends in screening rates, correlates of these rates with factors that may influence screening, and linkages or comparisons of NHIS data with other surveys or sources of information. We summarize knowledge gained in cancer screening for each of these three categories and identify areas that could benefit from more research. We highlight some of the new information available for the first time on the Cancer Control Module of the 2000 NHIS as fresh opportunities for cancer control research. Finally, we describe how the Cancer Control Supplements to the NHIS are integrated with the objectives of and developments in national cancer surveillance research that have emerged from federal planning efforts and collaborations with national partners in cancer surveillance in recent years.
