Impact of the Cancer Prevention and Control Research Network: Accelerating the Translation of Research Into Practice. Am J Prev Med 2017; 52:S233-S240. [PMID: 28215371 PMCID: PMC5812747 DOI: 10.1016/j.amepre.2016.08.026] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2016] [Revised: 07/29/2016] [Accepted: 08/18/2016] [Indexed: 12/18/2022]
Abstract
The Cancer Prevention and Control Research Network (CPCRN) is a thematic network dedicated to accelerating the adoption of evidence-based cancer prevention and control practices in communities by advancing dissemination and implementation science. Funded by the Centers for Disease Control and Prevention and National Cancer Institute, CPCRN has operated at two levels: Each participating network center conducts research projects with primarily local partners as well as multicenter collaborative research projects with state and national partners. Through multicenter collaboration, thematic networks leverage the expertise, resources, and partnerships of participating centers to conduct research projects collectively that might not be feasible individually. Although multicenter collaboration is often advocated, it is challenging to promote and assess. Using bibliometric network analysis and other graphical methods, this paper describes CPCRN's multicenter publication progression from 2004 to 2014. Searching PubMed, Scopus, and Web of Science in 2014 identified 249 peer-reviewed CPCRN publications involving two or more centers out of 6,534 total. The research and public health impact of these multicenter collaborative projects initiated by CPCRN during that 10-year period were then examined. CPCRN established numerous workgroups around topics such as: 2-1-1, training and technical assistance, colorectal cancer control, federally qualified health centers, cancer survivorship, and human papillomavirus. This paper discusses the challenges that arise in promoting multicenter collaboration and the strategies that CPCRN uses to address those challenges. The lessons learned should broadly interest those seeking to promote multisite collaboration to address public health problems, such as cancer prevention and control.

Abstract
Asian communities in North America include large numbers of immigrants with limited English proficiency. Hepatitis B virus (HBV) infection is endemic in most Asian countries and, therefore, Asian immigrant groups have high rates of chronic HBV infection. We conducted a group-randomized trial to evaluate the effectiveness of a hepatitis B English as a second language (ESL) educational curriculum for Asian immigrants. Eighty ESL classes were randomized to experimental (hepatitis B education) or control (physical activity education) status. Students who reported they had not received a HBV test (at baseline) completed a follow-up survey 6 months after randomization. The follow-up survey assessed recent HBV testing and HBV-related knowledge. Provider reports were used to verify self-reported HBV tests. The study group included 218 students who reported they had not been tested for HBV. Follow-up surveys were completed by 180 (83%) of these students. Provider records verified HBV testing for 6% of the experimental group students and 0% of the control group students (P = 0.02). Experimental group students were significantly (P < 0.05) more likely than control group students to know that immigrants have high HBV infection rates, HBV can be spread during sexual intercourse and by sharing razors, and HBV infection can cause liver cancer. Our ESL curriculum had a meaningful impact on HBV-related knowledge and a limited impact on HBV testing levels. Future research should evaluate the effectiveness of ESL curricula for other immigrant groups and other health topics, as well as other intervention approaches to increasing levels of HBV testing in Asian immigrant communities.

Factors associated with hepatitis B testing among Vietnamese Americans. J Gen Intern Med 2010; 25:694-700. [PMID: 20306150 PMCID: PMC2881980 DOI: 10.1007/s11606-010-1285-1] [Citation(s) in RCA: 46] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/03/2009] [Revised: 01/22/2010] [Accepted: 01/30/2010] [Indexed: 02/06/2023]
Abstract
BACKGROUND Chronic hepatitis B and hepatitis B-associated liver cancer is a major health disparity among Vietnamese Americans, who have a chronic hepatitis B prevalence rate of 7-14% and an incidence rate for liver cancer six times that of non-Latino whites. OBJECTIVE Describe factors associated with hepatitis B testing among Vietnamese Americans. DESIGN A population-based telephone survey conducted in 2007-2008. PARTICIPANTS Vietnamese Americans age 18-64 and living in the Northern California and Washington, DC areas (N = 1,704). MAIN MEASURES Variables included self-reports of sociodemographics, health care factors, and hepatitis B-related behaviors, knowledge, beliefs, and communication with others. The main outcome variable was self-reported receipt of hepatitis B testing. KEY RESULTS The cooperation rate was 63.1% and the response rate was 27.4%. Only 62% of respondents reported having received a hepatitis B test and 26%, hepatitis B vaccination. Only 54% knew that hepatitis B could be transmitted by sexual intercourse. In multivariable analyses, factors negatively associated with testing included: age 30-49 years, US residence for >10 years, less Vietnamese fluency, lower income, and believing that hepatitis B can be deadly. Factors positively associated with testing included: Northern California residence, having had hepatitis B vaccination, having discussed hepatitis B with family/friends, and employer requested testing. Physician recommendation of hepatitis B testing (OR 4.46, 95% CI 3.36, 5.93) and respondent's request for hepatitis B testing (OR 8.37, 95% CI 5.95, 11.78) were strongly associated with test receipt. CONCLUSION Self-reports of hepatitis B testing among Vietnamese Americans remain unacceptably low. Physician recommendation and patient request were the factors most strongly associated with test receipt. A comprehensive effort is needed to promote hepatitis B testing in this population, including culturally-targeted community outreach, increased access to testing, and physician education.

Abstract
Hepatitis B testing is recommended for immigrants from countries where hepatitis B infection is endemic. However, only about one-half of Chinese in North America have received hepatitis B testing. We conducted a randomized controlled trial to evaluate the effectiveness of a hepatitis B lay health worker intervention for Chinese Americans/Canadians. Four hundred and sixty individuals who had never been tested for hepatitis B were identified from community-based surveys of Chinese conducted in Seattle, Washington, and Vancouver, British Columbia. These individuals were randomly assigned to receive a hepatitis B lay health worker intervention or a direct mailing of physical activity educational materials. Follow-up surveys were completed 6 months after randomization. Self-reported hepatitis B testing was verified through medical records review. A total of 319 individuals responded to the follow-up survey (69% response rate). Medical records data verified hepatitis B testing since randomization for 9 (6%) of the 142 experimental group participants and 3 (2%) of the 177 control group participants (P = 0.04). At follow-up, a higher proportion of individuals in the experimental arm than individuals in the control arm knew that hepatitis B can be spread by razors (P < 0.001) and during sexual intercourse (P = 0.07). Our findings suggest that lay health worker interventions can impact hepatitis B-related knowledge. However, our hepatitis B lay health worker intervention had a very limited impact on hepatitis B testing completion. Future research should evaluate other intervention approaches to improving hepatitis B testing rates among Chinese in North America.

Abstract
BACKGROUND Hepatitis B virus (HBV) is a growing health issue in Canada, especially given that population growth is now largely the result of immigration. Immigrants from countries with high HBV prevalence and low levels of HBV vaccination have an excess risk of liver disease and there is a need for increased diligence in HBV blood testing and possibly vaccination among these populations. OBJECTIVE This study describes the sociodemographic characteristics associated with a history of HBV testing and HBV vaccination in immigrants from several countries with high HBV prevalence who are attending English classes. METHODS 759 adult immigrants attending English as a Second Language classes completed a self-administered questionnaire asking about sociodemographic characteristics and history of HBV testing and HBV vaccination. Descriptive statistics and adjusted ORs were calculated to explore these associations. RESULTS 71% reported prior HBV testing, 8% reported vaccination without testing, and 21% reported neither testing nor vaccination. Age, education and country of birth all showed significant effects for both testing and vaccination. CONCLUSIONS Health care practitioners need to be cognizant of HBV testing, and possibly vaccination, in some of their patients, including immigrants from countries with endemic HBV infection. Infected persons need to be identified by blood testing in order receive necessary care to prevent or delay the onset of liver disease as well as to adopt appropriate behaviours to reduce the risk of transmission to others. Close contacts of infected persons also require HBV testing and subsequent vaccination (if not infected) or medical management (if infected).

Abstract
BACKGROUND Chronic hepatitis B infection is the most common cause of liver cancer among Cambodians. Our objective was to describe Cambodian Americans' hepatitis B knowledge, testing, and vaccination levels. METHODS A community-based telephone survey was conducted in Seattle. Our study sample included 111 individuals. RESULTS Less than one half (46%) of our study group had received a hepatitis B blood test, and about one third (35%) had been vaccinated against hepatitis B. Only 43% knew that Cambodians are more likely to be infected with hepatitis B than whites. CONCLUSIONS Over 50% of our respondents did not recall being tested for hepatitis B. We identified important knowledge deficits about hepatitis B. Continued efforts should be made to implement hepatitis B educational campaigns for Cambodians.

Abstract
BACKGROUND Cardiovascular disease is a leading cause of death in the United States as well as in many countries around the world, including Vietnam. METHODS Using data from a household survey of Vietnamese American women aged 20-79 years in Seattle, Washington, collected in 2006 and 2007, we examined heart disease prevention practices. Multivariable analyses were conducted to examine the relationship between demographic factors and preventive behaviors. RESULTS A total of 1523 immigrant women completed interviews. The average daily consumption of fruits and vegetables was 3.5 servings, and 31% of our sample reported being physically active (engaging in at least 30 minutes of physical activity 5 or more days per week). Few respondents reported being current smokers (1.5%). Over three quarters of women had received a recent blood pressure check and a recent cholesterol check. Age and length of time in the United States were strongly associated with several cardiovascular prevention behaviors. CONCLUSIONS Our findings confirm the need for continued efforts to develop and implement targeted educational campaigns to reduce the risk of cardiovascular disease among Vietnamese American women.

Abstract
OBJECTIVE Although Chinese are one of the fastest growing minorities in Canada, there is little information about heart disease prevention behaviour in Chinese immigrants. Our objective was to examine the knowledge and practices of Chinese immigrants regarding heart disease prevention. METHODS 504 randomly selected Chinese adult immigrants participated in a community-based, in-person survey in Vancouver during 2005. The survey included questions on heart disease prevention knowledge and practices. RESULTS Although respondents were quite knowledgeable about heart disease risk factors, their behaviours to reduce heart disease risk were generally low. Thirteen percent of respondents consumed five or more servings of fruit/vegetables per day; 37% engaged in regular physical activity; 54% never used tobacco; 81% had received a blood pressure check in the past 2 years; and 54% had received a cholesterol test in the past 5 years. Differences were found in these behaviours by gender, age, English fluency, birth country and duration of residence in North America. The associations are presented between these demographic variables and heart disease prevention behaviours. CONCLUSION Heart disease prevention programs are needed in Chinese immigrant populations, especially aimed at increasing fruit/vegetable consumption and regular physical activity. Efforts are also needed to decrease tobacco use and to increase cholesterol testing.

Abstract
There is little information about the heart disease prevention behavior of Asian immigrants. Chinese are the largest Asian sub-group in the United States (US), and 69% of Chinese Americans are foreign-born. Our objective was to describe Chinese immigrants' heart disease prevention practices. A community-based, in-person survey of Chinese men and women was conducted in Seattle during 2005. Our study sample included 395 Chinese immigrants. Only 15% of the respondents consumed five or more servings of fruit/ vegetables per day, and less than one-third (31%) engaged in regular physical activity. Smoking rates were significantly higher among men (21%) than women (1%). About three-quarters (74%) of the study group had received a cholesterol test in the previous five years. Recent immigrants had higher levels of fruit/ vegetable consumption and physical activity than those who had been in the US for 10 years or more. Conversely, longer duration of US residence was positively associated with recent cholesterol testing. Heart disease prevention programs should be developed, implemented, and evaluated in Chinese immigrant populations. These efforts should specifically aim to increase fruit/ vegetable consumption and regular physical activity. Future efforts to increase cholesterol testing should focus on recent immigrants.

Abstract
BACKGROUND Little is known about hepatitis B (HBV) and liver cancer control in Chinese in Canada. Liver cancer, a significant health problem in Asia, is preventable and can be controlled through HBV blood testing, vaccination, and community education about HBV. OBJECTIVE The overall goal was to increase HBV testing and vaccination in Chinese adult Canadians. The objective was to present findings on HBV testing, vaccination and knowledge in Chinese immigrants. METHODS 504 randomly selected Chinese adult immigrants residing in Vancouver responded to the survey which examined HBV blood testing and vaccination practices, HBV knowledge levels and socio-demographic characteristics. Face-to-face interviews were conducted in Cantonese, Mandarin, or English. RESULTS 57% of participants reported that they had received HBV blood testing, 38% had been vaccinated, and 6% were known HBV carriers. There were gender differences, with lower rates of testing and vaccination, and higher chronic carrier rates, among men. Over 80% knew that HBV can be spread by asymptomatic persons and can cause cirrhosis and liver cancer. However, confusion existed about the routes of HBV transmission. INTERPRETATION A sizeable proportion of Chinese adult immigrants in Vancouver have not been tested or vaccinated for HBV. Knowledge level, especially about routes of HBV transmission, was low. This is a concern, given that chronic HBV infection is the most common cause of liver cancer in Asian North Americans. To improve knowledge, reduce risk of infection and the burden of chronic infection and its sequelae in immigrant populations, continuing educational efforts are needed.

Abstract
BACKGROUND Chinese North American women have high invasive cervical cancer rates and low screening rates. The cost-effectiveness of strategies to improve Pap testing rates for Chinese women living in Seattle, Washington and Vancouver, British Columbia was examined. OBJECTIVES To calculate the costs and cost-effectiveness of implementing two strategies to motivate women to obtain a Pap smear. RESEARCH DESIGN A three-armed randomized, controlled trial was conducted. Women in each of two interventions (high-intensity outreach and low-intensity mailing intervention) were compared to a group of women who received usual care. MEASURES Costs were captured via a group discussion of costs, accounting records, sampling of staff time logs, and estimation of costs and task times. Effectiveness was measured as the proportion of women in each intervention arm who reported receiving a Pap smear since the trial began. Cost-effectiveness was calculated as the incremental cost of screening each additional woman between an intervention arm and the control arm. RESULTS A greater percentage of women who received the outreach intervention had a Pap test than women who received mailed materials or women who were in the usual care arm. The intent-to-treat cost for each additional woman to be screened for a Pap test was $415 in the Outreach arm and $676 for the Direct Mailing arm. The outreach worker intervention, though more expensive overall, was more cost-effective than the mailing intervention. CONCLUSIONS Outreach intervention is cost-effective for sponsors and should be considered as a strategy to motivate Chinese women living in North America to seek cervical cancer screening.

Abstract
BACKGROUND Liver cancer, a significant health problem in Chinese, can be controlled through HBV blood testing, vaccination, and community education about HBV. The PRECEDE framework has been very helpful in identifying factors associated with health practices. OBJECTIVES The objective was to identify factors associated with HBV testing in Chinese Canadians, using the PRECEDE framework. METHODS Five hundred and thirty-three randomly selected Chinese Canadian adults were interviewed about HBV blood testing practices. Factors were grouped as predisposing, reinforcing and enabling. RESULTS Fifty-five percent had received HBV blood testing. Several predisposing factors, all reinforcing factors and one enabling factor were associated with HBV testing in bivariate analysis. A physician's recommendation for testing was the strongest factor associated with testing in multiple logistic regression analysis (OR=4.4, p<0.0001). INTERPRETATION Many Chinese Canadian adults in Vancouver have not been tested for HBV. Continuing educational efforts are needed and the PRECEDE framework can inform the development of health education interventions.

Abstract
BACKGROUND Chinese American men have relatively high smoking rates. However, there are limited data about the tobacco-related knowledge, attitudes, and beliefs of this racial/ethnic group. METHODS We conducted a community-based telephone survey in Seattle, Washington during 2004. Households were identified by applying a previously validated list of Chinese last names to an electronic version of the Seattle telephone book. Interviews were completed in Cantonese, Mandarin, or English. Survey items addressed tobacco knowledge, cultural beliefs, and practices. RESULTS The study sample included 168 Chinese American men. Current, former, and never smoking rates were 22%, 42%, and 36%, respectively. Current smokers were less likely to be proficient in English than never smokers, and were less likely to have a regular doctor than former smokers. They also had lower levels of knowledge about the health effects of tobacco, and were more likely to have traditional Chinese cultural beliefs about tobacco use than non-smokers. CONCLUSION Tobacco use continues to be a public health problem among Chinese American men. Smoking cessation programs should target men with limited English proficiency and those without a regular source of health care. Educational materials should specifically address the negative health effects of smoking. They should also both acknowledge and address Chinese cultural beliefs about tobacco use.

INTRODUCTION Chinese immigrants to the United States experience high rates of liver cancer. Chronic carriage of hepatitis B virus (HBV) is the most common underlying cause of liver cancer among Chinese Americans. Our objective was to describe Chinese immigrants' hepatitis B knowledge, testing, and vaccination levels. METHODS A community-based, in-person survey of Chinese men and women was conducted in Seattle during 2005. Our study sample included 395 individuals. RESULTS Less than one-half (48%) of our study group indicated they had received a hepatitis B blood test, and about one-third (31%) indicated they had been vaccinated against hepatitis B. The proportions of respondents who knew HBV can be spread during childbirth, during sexual intercourse, and by sharing razors were 70%, 54%, and 55%, respectively. Less than one-quarter of the study group knew that HBV cannot be spread by eating food that was prepared by an infected person (23%) and by sharing eating utensils with an infected person (16%). DISCUSSION Over 50% of our respondents did not recall being tested for HBV. Important knowledge deficits about routes of hepatitis B transmission were identified. Continued efforts should be made to develop and implement hepatitis B educational campaigns for Chinese immigrant communities.

Abstract
OBJECTIVE Data regarding disease prevention behaviors among Asian-American populations are limited. This study explored the beliefs of older Chinese Americans toward colorectal cancer screening modalities, including fecal occult blood testing (FOBT). DESIGN AND PARTICIPANTS We conducted 30 semistructured, open-ended, qualitative interviews in Mandarin and Cantonese, focusing on colorectal cancer prevention and health-seeking behavior. Participants were Chinese patients 50-79 years of age recruited from a community clinic in Seattle, Washington. RESULTS When asked about colorectal cancer prevention, interviewees discussed such concepts as maintenance of positive energy (qi) and spirit (jing shen) and moderation of exercise and diet. Until prompted, participants did not discuss FOBT. Interviewees believed that colorectal cancer was caused by diets high in foods with "heat" (huo qi) or by intestinal toxins from frequent constipation. Participants presumed that FOBT is unnecessary in the absence of symptoms. CONCLUSIONS Patients in our study expressed beliefs about health promotion and causes of colorectal cancer that differed from Western biomedical concepts. Failure to recognize these different beliefs may create inadvertent confusion among elderly Chinese-American patients. Health promotion programs to increase colorectal cancer screening must incorporate these concepts to improve cultural relevance among Chinese-American patients.

Abstract
OBJECTIVE To compare screening mammography and Pap testing among Chinese women in Seattle, Washington to Vancouver, and British Columbia. METHODS Using community-based sampling methods, trilingual female interviewers surveyed Chinese women in Seattle and Vancouver. Multiple preventive health behaviors and health care access variables were assessed. Mammography analysis included 409 women aged 50-74 years. Pap testing analysis included 973 women aged 20-69 years. Main outcome measures were ever use and use in the last 2 years of screening mammography and Pap testing. RESULTS Chinese women in Vancouver were younger, more educated and fluent in English. Unadjusted rates of mammography and Pap testing were similar between the two cities. Provider type was consistently associated with screening in both cities; female providers had the highest rates and Chinese male providers the lowest. Adjusted logistic regression analysis demonstrated similar mammography use in the two cities. However, for Pap testing, women in Seattle had higher odds of screening compared to Vancouver. CONCLUSION Despite universal health care coverage and baseline characteristics typically associated with greater utilization of preventive screening services, Chinese women in Vancouver did not have higher rates of screening mammography and Pap testing compared to Chinese women in Seattle.

Abstract
BACKGROUND Asian Americans and Pacific Islanders (AAPI) have better colorectal cancer survival than other racial populations. However, immigrants face challenges that may place them at higher risk for late diagnosis and death. METHODS To compare survival between the foreign- and U.S.-born, we identified 17,302 AAPI colorectal cancer patients between 1973 and 1998 from the Surveillance, Epidemiology, and End-Results (SEER) Program. Patients were categorized as foreign-born or U.S.-born using multiple imputation methods. RESULTS Foreign birth was associated with higher risk for death from any cause (hazard ratio [HR] 1.29; 95% CI 1.23-1.36) and with modestly higher risk after adjustment for selected demographic characteristics (HR 1.13; 95% CI 1.05-1.21) and registry site (HR 1.05; 95% CI 0.98-1.14). Although foreign-born AAPI were more likely to present later, additional adjustment for cancer stage reduced but did not eliminate their higher risk of death (HR 1.09; 95% CI 1.01-1.18) CONCLUSIONS Compared to the U.S.-born, foreign-born AAPI have poorer survival following colorectal cancer diagnosis. Future investigation of the care processes after diagnosis may be important in understanding these differences.

BACKGROUND Though breast cancer is the most common malignancy among Chinese women, screening mammography is underutilized. This study examined barriers and facilitators of screening mammography among Chinese Canadian women. METHODS Using community-based sampling, Chinese women in British Columbia were interviewed in 1999 about multiple preventive health behaviours. We included 213 women in the mammography analysis; main outcome measures were ever having a mammogram and routine mammography. RESULTS Seventy-five percent of women 50 to 79 years old reported ever having had a mammogram, and 53% had two or more mammograms within the last five years. Receiving a recommendation for a mammogram from medical personnel or from a family member, and believing that cancer cannot be prevented by faith were independently associated with both screening outcomes. CONCLUSIONS A multifaceted approach to screening mammography promotion in Chinese Canadian women is suggested. Interventions that include education of and by medical providers and family members should be considered.

Abstract
BACKGROUND Little information is available on the breast cancer screening behavior of Cambodian American women. METHODS We identified households from multiple sources using Cambodian surnames and conducted a cross-sectional survey, administered by bilingual and bicultural interviewers. Breast cancer screening stages of adoption were examined based on concepts from the transtheoretical model of behavioral change. RESULTS Our response rate was 73% (398 women in clinical breast exam (CBE) analysis, and 248 in mammography analysis) with approximately 25% each in the maintenance stage. We found significant associations between screening stage with physician characteristics. Asian American female physician increased the likelihood of being in the maintenance stage (CBE, OR = 10.1, 95% CI 2.8-37.1; mammogram, OR = 74.7,95% CI 8.3-674.6), compared to Asian American male physician with precontemplation/contemplation stage as our referent outcome. CONCLUSION Results from this study support the need to promote regular breast cancer screening among Cambodian American women.

Abstract
With the changes in health care occurring in South Africa, new functions concerning the community nurse are being presented. The goal of the study was to explore and describe the role of the community nurse in health committees. An explorative, descriptive design was used and the empirical part was undertaken within the context of a metropolitan local authority. After conducting a literature study, six major roles of the community nurse on health committees were identified. After that a questionnaire was presented to community nurses to explore and describe their perceptions about the role of the community nurse on health committees. An interview schedule based on the literature study was drafted for presentation to selected members of health committees. Lastly guidelines describing the role of the community nurse on health committees were developed based on the findings of the study.

Abstract
An animal model was used to study the pathogenesis of pin track infection. The roles of fluid accumulation around the pin/bone interface and mechanical loosening of the pin were specifically studied. In addition, the spread of bacteria in relation to the clinical appearance of the pin track was assessed. This study demonstrated that fluid accumulation around the interface is an important factor in the spread of infection from the superficial wound track to the medulla of the bone. Spread occurs despite the absence of mechanical pin loosening, and can occur before any clinical features of infection are apparent.

Abstract
CONTEXT Timely adoption of clinical practice guidelines is more likely to happen when the guidelines are used in combination with adjuvant educational strategies that address social as well as rational influences. OBJECTIVE To implement the conservative, evidence-based approach to low-back pain recommended in national guidelines, with the anticipated effect of reducing population-based rates of surgery. DESIGN A randomized, controlled trial. SETTING Ten communities in western Washington State with annual rates of back surgery above the 1990 national average (158 operations per 100,000 adults). PARTICIPANTS Spine surgeons, primary care physicians, patients who were surgical candidates, and hospital administrators. INTERVENTION The five communities randomized to the intervention group received a package of six educational activities tailored to local needs by community planning groups. Surgeon study groups, primary care continuing medical education conferences, administrative consensus processes, videodisc-aided patient decision making, surgical outcomes management, and generalist academic detailing were serially implemented over a 30-month intervention period. OUTCOME MEASURE Quarterly observations of surgical rates. RESULTS After implementation of the intervention, surgery rates declined in the intervention communities but increased slightly in the control communities. The net effect of the intervention is estimated to be a decline of 20.9 operations per 100,000, a relative reduction of 8.9% (P = 0.01). CONCLUSION We were able to use scientific evidence to engender voluntary change in back pain practice patterns across entire communities.

Abstract
OBJECTIVE To develop simple scales to measure a Chinese immigrant's adoption of Western eating patterns (dietary acculturation). STUDY DESIGN AND PARTICIPANTS Data are from 244 less-acculturated women of Chinese ethnicity living in Seattle, Wash, and Vancouver, British Columbia, Canada. Interviewers collected information on sociodemographic characteristics, acculturation indices, items that reflect Western and Chinese dietary behavior, and consumption of fruits, vegetables, and fat. STATISTICAL ANALYSES Analysis of variance and linear regression analyses examined associations among dietary measures and acculturation variables, controlling for age, education, and city of residence. RESULTS We developed 2 scales to assess dietary acculturation: the Western Dietary Acculturation Scale and the Chinese Dietary Acculturation Scale, measuring Western and Chinese eating behavior, respectively. Although the population in this study was a less-acculturated sample, most participants reported some Western dietary practices, such as drinking milk (78%), eating cheese (78%), eating at Western fast-food restaurants (56%), and eating between meals (72%). Younger, highly educated women employed outside the home had the highest Western dietary acculturation scores (P < .001). Women with high scores on the Western scale reported higher-fat dietary behaviors and had increased fruit and vegetable intake since immigration compared to those with lower scores (P < .001). There was good agreement between the dietary acculturation scales and traditional acculturation indicators (P < .001). APPLICATIONS Nutrition programs for immigrant/minority groups may be more effective if they are tailored to level of dietary acculturation. Therefore, the ability to accurately assess dietary acculturation is an important component of nutrition education, interventions, and counseling in these populations.

Abstract
Our aim was to describe and identify factors associated with breast cancer screening among Cambodian American women. We conducted a cross-sectional survey of 1,365 households using bilingual and bicultural interviewers. We found that low proportions of Cambodian American women were up to date on their clinical breast examinations (CBE; 42%) and mammograms (40%). More than 80% of women with female physicians have had at least one prior screening, and 52% have had the tests recently. Women with male Asian American physicians were less likely to have had screening as compared to women with female non-Asian physicians: ever had CBE (odds ratio [OR], 0.26); recent CBE (OR, 0.39); ever had mammogram (OR, 0.36); and recent mammogram (OR, 0.22). Breast cancer screening among Cambodian American women lags behind the general U.S. population. Tailored promotion efforts should address barriers and promote cancer screening by physicians, staff, and organizations serving this population.

Abstract
Southeast Asian immigrants have lower levels of Pap testing than any other racial/ethnic group in the US, and are particularly unfamiliar with western culture and biomedical concepts of prevention. We completed an ethnographic study (N = 42) focusing on cervical cancer screening among Cambodian American women. We also conducted a community-based survey (N = 413) to examine the generalizability of our qualitative results. This report summarizes the results, and describes how we used our findings to influence the content of a multifaceted intervention program targeting Cambodian immigrants. The following constructs were found to be barriers to cervical cancer control: a traditional orientation to the prevention, causation, and treatment of disease; lack of familiarity with western early detection concepts; low levels of knowledge about cervical cancer; concerns about the Pap testing procedure; and health care access issues. In general, the quantitative results confirmed our ethnographic findings. The intervention program, which is delivered by bicultural outreach workers, includes home visits, presentations at small group meetings, barrier-specific counseling, use of a Khmer-language video, and tailored logistic assistance (e.g., transportation and medical interpretation). Both the video and presentation provide cultural context while simultaneously addressing multiple barriers to screening (e.g., women's fear of surgery and preference for female providers). Outreach workers are trained to counsel women about 10 potential barriers including avoidance of biomedicine, perceptions that gynecologic exams are embarrassing, and lack of English proficiency. Our results reinforce the importance of considering health problems within the context of a population's traditional belief systems and daily routines.

Abstract
STUDY DESIGN This study used a prospective cohort design. OBJECTIVE To examine factors associated with favorable self-reported patient outcomes 1 year after elective surgery for degenerative back problems. SUMMARY OF BACKGROUND DATA Many previous studies addressing the results of low back surgery have been conducted in academic institutions or by single surgeons. As part of a quality improvement effort, surgeons in private practice led a community-based outcomes management project in Washington State. METHODS Patients ages 18 and older with the following diagnoses were eligible for the study: degenerative changes, herniated disc, instability, and spinal stenosis. Nine orthopedists and neurosurgeons enrolled a total of 281 patients. Participants were asked to complete baseline and 1-year follow-up surveys. Data concerning diagnoses, clinical signs, and operative procedures were provided by the surgeons. The researchers examined sociodemographic characteristics, self-reported symptoms before surgery, preoperative clinical signs, diagnoses, and operative procedures associated with three primary outcomes: better functioning, improved quality of life, and overall treatment satisfaction. RESULTS Follow-up surveys were completed by 236 (84%) of the enrolled patients. Approximately two thirds of the study participants reported much better functioning (65%), a great quality of life improvement (64%), and a very positive perspective about their treatment outcome (68%). The following variables were associated with worse patient outcomes: older age, previous low back surgery, workers' compensation coverage, and consultation with an attorney before surgery. Patients undergoing a fusion procedure were more likely to report good outcomes. CONCLUSIONS The authors' experience indicates that community-based outcomes data collection efforts are feasible and can be incorporated into usual clinical practice. The study results indicate that compensation payments and litigation are two important predictors of poor outcomes after low back surgery in community practice. Because of small numbers, varied diagnoses, and possible selection bias, the findings with respect to fusion should be interpreted cautiously.

Abstract
Improving the health status of minority populations in the United States is a major public health challenge. This report describes an anthropological approach to obtaining information needed for designing and evaluating a culturally appropriate dietary intervention for Chinese-Americans. Ninety-minute qualitative interviews were conducted with 30 less-acculturated Chinese-American women in their native language (Cantonese or Mandarin), soliciting information from participants regarding usual food consumption; knowledge, attitude, and beliefs about diet and disease; and factors that influence food choices. Interviews were recorded, translated, transcribed, and coded for themes. Two focus groups with 6 participants each were conducted to cross-validate the interview findings. Among our participants, breakfast was usually the first meal to be "Westernized," largely for reasons of convenience. Food quality, cost, and availability were some of the most important predictors of dietary change after immigration to the United States. Respondents said that there was a strong connection between diet and disease. However, they were not familiar with US dietary guidelines, food labels, or other sources of dietary information, but reported that friends and Chinese newspapers were their primary source of nutrition information. We used these findings to develop quantitative dietary survey instruments adapted for Chinese-Americans. This type of qualitative groundwork is an important precursor to the design, implementation, and evaluation of dietary interventions for minorities.

Abstract
BACKGROUND Vietnamese have higher liver cancer rates than any other racial/ethnic group in the United States. Approximately 80% of liver cancers are etiologically associated with hepatitis B virus (HBV) infection, which is endemic in Southeast Asia. METHODS A telephone survey of randomly selected Vietnamese households (n = 75) was conducted during 1998 to examine HBV knowledge among Seattle's Vietnamese community. The questionnaire included items related to the transmission of HBV, the possible sequelae of infection, and disease prevention. RESULTS The response rate was 70% among reachable and eligible households. Prior to being provided with a description of the disease, two thirds of our respondents had heard of HBV infection. Less than 60% knew that asymptomatic individuals can transmit the disease to others. Most thought that HBV infection can cause liver cancer (63%) and death (80%). However, only a minority knew that infection can be lifelong (38%) and incurable (22%). Finally, 28% had never heard of the HBV vaccine. There were significant associations between knowledge and educational level as well as home ownership. CONCLUSIONS The findings suggest that Vietnamese immigrants have low levels of knowledge about HBV infection, and indicate a need for targeted educational interventions aimed at reducing HBV-related liver cancer mortality.

Abstract
Southeast Asian women have higher invasive cervical cancer incidence rates and lower Pap testing frequencies than most other racial/ethnic groups in the United States. However, there is little information about the cervical cancer screening behavior of Cambodian-American women. Cambodian residents of Seattle were surveyed in person during late 1997 and early 1998. The PRECEDE model was used to guide the development of items that assessed predisposing, reinforcing, and enabling factors associated with cervical cancer screening participation. The estimated overall survey response was 72%. Four hundred thirteen women completed our questionnaire. Approximately one-quarter (24%) of the respondents had never had a Pap test, and over one-half (53%) had not been screened recently. The following variables were positively associated with a history of at least one Pap smear: younger age, greater number of years since immigration, belief about Pap testing for postmenopausal women, prenatal care in the United States, and physician recommendation. Women who believed in karma were less likely to have ever been screened for cervical cancer than those who did not. Six variables independently predicted recent screening: age; beliefs about regular checkups, cervical cancer screening for sexually inactive women, and the prolongation of life; having a female doctor; and a previous physician recommendation for Pap testing. The study findings indicate that culturally specific approaches might be effective in modifying the cervical cancer screening behavior of immigrant women. Programs targeting Cambodian-Americans are likely to be more effective if they are multifaceted and simultaneously address predisposing, reinforcing, and enabling factors.

Abstract
BACKGROUND Southeast Asian women have higher invasive cervical cancer rates than any other U.S. racial/ethnic population subgroup, and their levels of Pap testing do not even approach the year 2000 goals. Video is a particularly useful medium for cancer education in Cambodian refugee communities because of low literacy levels and high rates of VCR ownership. METHODS The authors produced a motivational Pap-testing video for Cambodian American women. The 18-minute Khmer-language video is entitled "The Preservation of Traditions." Content, with respect to cervical cancer screening barriers and facilitators, was guided by intensive qualitative data collection. Barriers addressed were: beliefs that traditional postpartum practices protect against cervical disease, Cambodians do not get cervical cancer, and screening is unnecessary; fear of cancer as well as surgery; lack of understanding about preventive concepts and familiarity with the Pap test; concerns about embarrassment and pain; and problems with transportation and child care. Facilitators included the availability of female physicians and interpreters. A community coalition of Cambodian women and two community advisors participated in all aspects of the video development and production. Video techniques frequently used in American productions were adapted to the target audience. For example, cultural context was provided, use of biomedical terminology minimized, role modeling emphasized, and testimonial accounts avoided. CONCLUSION The processes used to translate empirical evidence into meaningful educational messages, and to adapt American behavioral change techniques to Cambodian cultural norms, are generalizable to other less acculturated immigrant groups and cancer education topics.

Abstract
OBJECTIVE To examine back and neck hospitalizations in the Province of Ontario and Washington State. Because of their different organization and financing, there has been considerable interest in comparing healthcare systems in Canada and the United States. Features of healthcare systems might be expected to result in greater variations in care for elective than urgent conditions. DATA SOURCE Automated hospital discharge databases. STUDY DESIGN Previously developed algorithms were used to identify surgical and nonsurgical hospitalizations for back and neck problems in the administrative databases. We compared overall rates of hospitalization and lengths of hospital stay in Ontario and Washington as well as small area variations within the province and state. PRINCIPAL FINDINGS Surgical back and neck hospitalizations were three times as common in Washington, but medical hospitalizations were twice as common in Ontario. Provincial lengths of stay were longer for both surgical and nonsurgical hospitalizations. Admission rates varied substantially and significantly among small areas in both Washington and Ontario. Variations in hospital length of stay were greater in Ontario, particularly for nonsurgical back and neck hospitalizations. CONCLUSION The two jurisdictions had very different patterns of hospital utilization for one of the most common health problems seen by physicians. Our results suggest that the global controls on hospital budgets and access to technology in Ontario were associated with lower rates of surgery, higher rates of hospital-based medical care, and longer lengths of stay. They also indicate that the utilization review process in Washington was associated with lower small area variation rates for medical back care.

Abstract
Low income and minority women continue to have relatively low breast cancer screening rates. Since physician recommendation is one of the most important determinants of mammography participation, we aimed to characterize the breast cancer screening knowledge of primary care providers serving a socially disadvantaged population. The study was conducted at the Adult Medicine Clinic of Seattle's county hospital. All attending physicians, resident physicians, and mid-level practitioners were asked to complete a questionnaire in the spring of 1995. Forty-nine of 52 (94%) eligible providers completed the survey. The respondents generally agreed with published guidelines for screening mammography use. In contrast, they had relatively low levels of knowledge about breast cancer risk factors and the effectiveness of other breast cancer screening methods. Additionally, providers tended to over-estimate their breast cancer screening knowledge and skills. For example, 69% believed that they could answer patients' questions about mammography, but only 23% were aware of Medicaid's reimbursement policy for the procedure. For some variables, attending physicians were no more knowledgeable than resident physicians. Our results reinforce the need for increased preventive care training in medical schools and primary care residency programs. Educational programs for providers serving disadvantaged populations might usefully focus on pragmatic issues such as institutional costs and public payer reimbursement policies.

Abstract
OBJECTIVE To describe and compare trends in hospital admission rates for mechanical neck and back problems between 1982 and 1992 in Ontario and the United States. DESIGN A descriptive analysis of hospital admissions, with data for Ontario extracted from the Canadian Institute for Health Information database and data for the US extracted from the National Hospital Discharge Survey. SETTING All acute care hospitals in Ontario and a probability sample of acute care hospitals in the US. PATIENTS Adults aged 20 years or more who were admitted to an acute care hospital for mechanical neck or back problems in 1982, 1987 or 1992. Mechanical neck and back problems were defined using an algorithm developed by the study team. OUTCOME MEASURE Hospital admission rate per 100,000 adults. RESULTS Between 1982 and 1992 the hospital admission rate for medically treated cases decreased by 52% in Ontario and by 75% in the US. Over the same period the admission rate for surgically treated cases increased by 14% and by 35% respectively. By 1992 the admission rate for medically treated cases in the US was 23% higher than that in Ontario, whereas the rate for surgically treated cases was 164% higher. CONCLUSIONS The hospital-based medical or surgical treatment of mechanical neck and back problems provides an example of discretionary care. The higher admission rates for surgery in the US may reflect a larger supply of surgical specialists and imaging units. Further work is needed to confirm these findings for other types of discretionary care and to compare the appropriateness of care and clinical outcomes for discretionary care in these 2 jurisdictions.

Abstract
BACKGROUND Low-income, minority, and inner city women have breast cancer screening rates that are below those of the general population. METHODS The authors surveyed women who received primary care at Seattle's county hospital about their mammography behaviors in early 1995. Data were analyzed within the context of the PRECEDE framework. RESULTS Only half (48%) of the women were obtaining regular screening. Breast cancer and mammography beliefs differed by racial group. The following factors differentiated between inner-city women who were and were not regular users: mammography beliefs concerning early detection of disease, pressure from the machine causing breast cancer, and cost (these were less important among white women than members of other racial groups); previous physician discussions, concerns about appointment scheduling, and transportation problems; and social support from physicians, family, and friends. CONCLUSION Interventions to encourage regular screening among inner-city women should address predisposing, enabling, and reinforcing factors.

Abstract
BACKGROUND Most research on mammography utilization has been conducted among middle-class women. There is a need for research to identify factors affecting mammography utilization among low-income women to develop effective interventions for this underserved subgroup. METHODS An expanded theory of reasoned action guided this research among low-income inner-city women who use a public hospital. Qualitative interviews were conducted to develop a questionnaire with items relevant to this population. The questionnaire included 5 affect measures, 13 behavioral beliefs, 5 sources of influence, and 6 facilitator/constraint measures. The survey was mailed to 584 women ages 50 to 69 identified through the hospital database. RESULTS After those ineligible and undeliverable were excluded, responses rates were obtained from 361 women (84% adjusted response rate). Sixty-six percent had a mammogram within the previous year and 58% were very sure that they would get a mammogram in the next year. Affect, attitude, subjective norm, and facilitator scores were computed. All four constructs had significant correlations (r = 0.38 to 0.41) with intention to get a mammogram in the next year and all had significant multiple regression weights (R = 0.54). All but three items making up the model components were significantly correlated with screening intention. CONCLUSIONS The data from applying a behavioral model indicate that intervention efforts to increase mammography utilization among low-income women should target all four model components. A clinic-based intervention could use multiple methods to deliver messages developed to target each of the model component items found to be associated with mammography intention.

Conflicting national recommendations and the use of screening mammography: does the physician's recommendation matter? THE JOURNAL OF THE AMERICAN BOARD OF FAMILY PRACTICE 1997; 10:88-95.

Abstract
BACKGROUND This study evaluated whether women's perceptions of the conflicting recommendations for breast cancer screening were associated with decreased use of mammography. METHODS We conducted a random-digit-dial telephone survey of 1024 women in four communities of western Washington State. In addition to collecting data for demographics, beliefs about mammography, and insurance coverage, we inquired whether the respondents were aware of any conflicting recommendations about when to begin or how frequently to perform screening mammography, whether their physicians had recommended a mammogram, and whether they were likely to do what their physicians recommended. After grouping women according to whether they perceived conflicting recommendations, we used chi-square statistics to compare the distribution of proportions of women by age, race, household income, education, and insurance coverage. To estimate the odds of their having a mammogram in the previous 2 years (yes or no), we used multivariate logistic regression and included the above variables as covariates. RESULTS Sixty-two percent of eligible women completed the survey, and 49 percent (479 of 985) perceived conflicting recommendations. The association between perceiving conflict and mammography use was not significant. Eighty-three percent of women who perceived conflicting recommendations reported being more comfortable using their own judgment about getting the procedure. After controlling for whether women perceived conflicting recommendations and all other factors, women who said they followed their physician's advice but did not recall their physician recommending mammography were 71 percent less likely to have received a recent mammogram than were women who reported their physician did recommend it (odds ratio 0.29, confidence interval 0.16-0.51). CONCLUSIONS The conflicting recommendations surrounding breast cancer screening are not influencing women's choices about mammography. The physician recommendation and women's self-reported likeliness to follow it are the most important factors associated with mammography use.

Abstract
Decisions about back pain treatment are often made in the presence of both physician and patient uncertainty. Therefore, we developed a computerized, interactive video program to help patients make informed decisions about undergoing low back surgery. Program development was guided by the shared decision-making model, a comprehensive literature synthesis, information from administrative databases, and focus groups of patients and physicians. Core segments are tailored to each patient's age and diagnosis; and include a narrative, excerpts from patient interviews, animated graphics illustrating spinal anatomy, and tabular summaries of the benefits and risks of both surgical and non-surgical treatment. As part of a multifocal information dissemination effort, interactive videodiscs were placed in five medical facilities in two Washington State counties. Patients (N = 239) who viewed the video program completed short evaluation forms. The majority rated the video's understandability (84%) and interest (64%) as very good or excellent. Most patients felt the amount of information provided was appropriate (75%) and over half (56%) believed the discussion of surgical versus non-surgical treatment was completely balanced. Fewer patients (17%) remained undecided about therapy after watching the program than before (29%). We conclude that interactive videodisc technology offers substantial promise as a means of involving patients in their own medical decision making.

Abstract
STUDY DESIGN The present study examines relationships between workers compensation coverage and the surgical treatment of patients with low back problems. OBJECTIVES To examine the mix of surgical procedures, reoperation rates, and resource use among patients receiving workers compensation and these with other sources of payment. SUMMARY OF BACKGROUND DATA There is evidence that patients with low back pain who receive workers' compensation have poorer clinical outcomes than other patients with back problems. METHODS The authors used data from Washington State's automated hospital discharge system for 1988 through 1991. The study group included 1502 patients receiving workers compensation and 2674 patients not receiving workers compensation. RESULTS If the patients were covered by workers' compensation, they were 1.37 times more likely to undergo surgery involving fusion (95% confidence interval, 1.04-1.80) and almost twice as likely to have a subsequent reoperation within 3 years of the index surgery (odds ratio, 1.80; 95% confidence interval, 1.50-2.15. CONCLUSIONS In Washington state, patients receiving workers' compensation have higher rates of low back fusion surgery and reoperations than other patients.

Abstract
Community organization has been viewed as a promising approach to changing preventive behaviors. We evaluated the impact of community organization strategies to promote breast cancer screening ordering by primary care physicians in Washington State. Physicians practicing in two intervention and two control communities were surveyed by mail pre-intervention (1989) and post-intervention (1993). Intervention activities targeting the health care sector included the formation of local physician planning groups, a series of informational mailings, medical office staff training sessions, and reminder system support. There were no significant post-intervention differences in the self-reported mammography ordering of physicians practicing in the intervention and control areas. Over the four-year study period, the proportions of physicians who ordered regular mammography increased by 36%. By 1993, over 80% of the respondents routinely used mammographic screening. Concerns about the high price of mammograms and inadequate insurance coverage were significantly reduced over time in both community pairs. Also, use of patient reminder systems increased significantly between 1989 and 1993. Secular trends resulting from diffusion of strategies to promote mammography were responsible for increases in physician ordering of the procedure. Year 2000 goals for breast cancer screening use by physicians may already have been met in some communities.

Abstract
Twenty children (six female), median age 24 months (range 12-156) who presented for application of a plaster jacket for scoliosis were studied pre-operatively with pulse oximetry overnight and on the first postoperative night. Pre-operatively the median (range) arterial oxygen saturation was 97 (95-98)%, although eight children had short episodes of desaturation to < 90%. Postoperatively the median saturation was unchanged, and nine children had short episodes of desaturation. Neither the presence of episodes of desaturation pre-operatively, nor the median or lowest saturation recorded were predictors of postoperative median saturation or the presence of episodes of desaturation. Despite the presumed reduction in chest wall compliance, the application of a plaster jacket for scoliosis in these young children was not associated with a significant change in their oxygenation.

Abstract
OBJECTIVE To investigate the frequency of placenta previa among Asian women. METHODS We conducted a population-based case-control study using Washington state birth certificate data from 1984-1987. Our study population included 810 women with pregnancies complicated by placenta previa and 2917 randomly selected controls. Unconditional logistic regression was used to estimate odds ratios (OR) and their 95% confidence intervals (CI), and interaction terms were used to examine effect modification. Potential confounding by maternal age, gravidity and parity, maternal smoking during pregnancy, and a history of abortion or cesarean delivery was adjusted for in the analysis. RESULTS The frequency of placenta previa during the study period was 3.3 per 1000 live births. Women of Asian origin were 86% more likely (OR 1.86, 95% CI 1.38-2.51) to have a delivery complicated by placenta previa than were white women. This association was stronger among women without a previous live birth (OR 2.51, 95% CI 1.57-4.01) than those who previously had experienced a live birth (OR 1.50, 95% CI 1.01-2.25). CONCLUSION Asian women residing in the United States are at increased risk of placenta previa. If confirmed by others, our results suggest that obstetricians should consider meticulous ultrasound evaluations during pregnancy to rule out the presence of placenta previa in Asian-American women.

Abstract
BACKGROUND To reduce breast cancer mortality, ways to promote the use of mammography screening among women age 50 and above are needed. Community organization may be a useful approach. METHODS The Washington State Community Breast Cancer Screening Project involved implementation of promotional activities initiated by physician and lay community boards in two communities. Two comparable communities served as controls for evaluation purposes. Random-digit-dial telephone interviews were used to assess recent use of mammography at baseline and follow-up in independent samples of women ages 50 to 75 from the four communities. The extent of exposure to intervention activities and the relationship between exposure to intervention activities and mammography use were estimated from data collected at follow-up. RESULTS Exposure to patient reminders from physicians, wallet reminder cards, and newspaper advertisements were consistently related to mammography use. Physician office staff encouragement and a display board were significantly related to mammography use only in Intervention Communities A and B, respectively. Neither exposure to promotional activities nor the change in prevalence of mammography use was significantly higher in the intervention communities than in the comparison communities at follow-up. CONCLUSIONS Although several activities were useful in promoting mammography use, organization of the community did not enhance efforts undertaken spontaneously by comparable communities.

Abstract
It has been demonstrated clearly that the use of regular screening mammography reduces mortality among women ages 50 years and over. The primary objective of this study was to investigate factors associated with repeat mammography participation. A random sample of women ages 50-75 years residing in four Washington State counties was surveyed by telephone during mid-1989. The Health Belief Model was used as a conceptual framework for the analysis. Three groups of women with different mammography experiences in the previous 5 years were compared: (a) nonusers; (b) onetime users; and (c) repeat users. The survey response rate was 72%, and the study sample included 1357 women. One time users were more likely to have health insurance coverage, to visit a gynecologist or other primary care physician regularly, and to believe mammography is more effective than breast self-examination; they were less likely to think that at least 1 in 10 women are diagnosed with breast cancer or that mammography is inconvenient to obtain than were nonusers. Factors associated with repeat versus onetime use included routinely visiting a gynecologist, thinking the lifetime risk of breast cancer is at least 10%, and perceiving a high personal susceptibility to disease. Women who perceive themselves as being vulnerable to breast cancer are more likely to report repeat mammograms. Visiting a gynecologist regularly is associated with repeat as well as initial mammography use. These factors could be considered as the focus of promotional efforts moves from encouraging women to obtain their first mammogram to encouraging repeat use.

Abstract
For several years, interest in clinical practice patterns has increased due to concerns about the costs and quality of health care. Our objectives were to examine recent trends and geographic variations in low back pain hospitalization. We analyzed data from a Washington State automated database for 1987-1992. Low back surgery rates in Washington changed little during the study years. In contrast, nonsurgical hospitalization rates fell from 15.5 to 5.1 per 10,000. The proportion of operations involving fusion decreased from 15.8% in 1987 to 11.7% in 1990, and then remained stable. During 1990, important county-to-county variations were observed in surgery rates, nonsurgical hospitalization rates, the proportion of operations involving fusion, and the percentage of surgical patients undergoing reoperation within 3 years. Wide county variations suggest that there may be overutilization or underutilization of low back pain treatments in some geographic areas. A more consistent approach to the management of back problems may benefit patients.

Abstract
Large computerized databases often arise from national surveys, insurance claims, and statewide health care registries. These databases are increasingly used to examine patterns of medical care and certain outcomes of care and may be helpful in planning clinical trials. They are highly representative of defined populations, but have limited clinical information. Methods have been developed to identify episodes of low back pain and to quantify the severity of unrelated, comorbid medical conditions. Pitfalls in analysis are discussed, including limitations of diagnosis and procedure coding, cross-sectional nature of most data, limited clinical detail, and the necessarily observational (not experimental) nature of any group comparisons. There is growing interest in expanding the clinical information in such databases, for both quality improvement and research purposes.

Abstract
OBJECTIVE To investigate the occurrence of placenta previa following a cesarean delivery. METHODS We conducted a case-control study using 1984-1987 Washington state birth certificate data. Analysis was restricted to women who reported one or more previous live births. The study population included 490 women with a pregnancy complicated by placenta previa and 1477 randomly selected controls. Unconditional logistic regression was used for statistical analysis. RESULTS After adjustment for confounding factors, the odds ratio for placenta previa in association with one or more previous cesarean deliveries was 1.48 (95% confidence interval 1.13-1.95). CONCLUSIONS Women with a history of cesarean delivery are 50% more likely to have a subsequent birth complicated by placenta previa than those without such a history. This magnitude of excess risk is lower than the relative risks reported in previous studies.

Abstract
STUDY DESIGN This study describes recent United States trends and regional variations in the management of low back pain. OBJECTIVES The authors investigated recent temporal trends and compared practices in different geographic regions. SUMMARY OF BACKGROUND DATA Controversy exists concerning the appropriate medical and surgical management of patients with low back pain. METHODS National Hospital Discharge Survey data from 1979 through 1990 were analyzed. Case selection was based on previously developed algorithms intended to exclude nonmechanical causes of back pain. RESULTS Over the period of study, nonsurgical hospitalizations for low back pain decreased dramatically. In contrast, low back operation rates, particularly for fusion surgery, increased substantially. In recent years, surgery and hospitalization rates were highest in the South and lowest in the West. CONCLUSIONS Rapidly increasing surgical rates and wide geographic variations suggest the need for a more consistent approach to back problems.

Abstract
The analysis, mobilization, and involvement of medical communities in two counties targeted for intervention by the Washington State Community Breast Cancer Screening Project is described. Principles of community organization were applied to the health care sectors in the counties, and the PRECEDE-PROCEED model was used as a conceptual framework for considering individual physician behavior. Quantitative and qualitative medical community assessment methods included a demographic study, a survey of primary care physicians, personal interviews with physicians, and medical office staff focus groups. In both intervention areas, physician planning groups selected, developed, and helped implement intervention activities targeting the health care sectors. These activities included informational mailings to physicians, training of medical office staff members and clinical mammographers, and support for a reminder system. The experience demonstrated that physicians practicing in medium-sized cities are willing to be active in community disease prevention programs.
