A survey of physician beliefs and self-reported practices concerning screening for early detection of cancer

Cancer is the second leading cause of death in the United States. Early detection of cancer greatly improves 5-year survival for many sites, and in 1980 the American Cancer Society (ACS) published recommendations for performing cancer screening with the goal of promoting early cancer detection in asymptomatic persons. This cross-sectional survey examined beliefs and practices related to six cancer screening tests and procedures in a group of 68 primary care physicians in a multi-specialty group practice in Houston, Texas. Constructs from the Health Belief Model and Social Cognitive Theory were used to identify factors that might influence performance of cancer screening. Physicians in this study reported greater compliance with ACS recommendations for performance than has been found in other studies, and there is an indication that some screening tests may be performed even when not indicated based on age-specific criteria. Respondents reported performing digital rectal examination, stool occult blood testing, and sigmoidoscopy more frequently in men than in women. No belief factor emerged as being associated with performance of all screening procedures, and associations that were noted for some procedures were not consistent across patient age and gender groups. Some possible directions for further research and development of programs to promote the appropriate and cost effective use of cancer screening are physician education to include information about age and gender appropriate guidelines for screening and opportunities for skills training and practice workshops for some procedures.

The information-seeking behavior of cancer outpatients: a description of the situation

The information-seeking behavior of cancer outpatients has been studied with the purpose of collecting data for the development of an educational intervention: stimulating communication between cancer outpatients and their specialists. The intention to seek information, the realization of the intention and the reasons for not realizing it are measured with several qualitative and quantitative methods: written questionnaires (n = 60, n = 18), audio records (n = 40) and focus group interviews (n = 19). Not every patient (58%) intends to discuss topics of illness and treatment with the specialist. Possible incentives to plan a discussion with the specialist are experienced uncertainty, fear and dissatisfaction with information received. In 22% of cases cancer outpatients do not realize their intention, and in 25% of cases the realization of the intention is due to the initiative of the specialist or the patient's companion. The information-seeking behavior of cancer outpatients appears to be influenced by several factors, including patients' needs, values and beliefs; unexpected situations; patients' skills; and specialists' and companions' behavior.

A meta-analysis of studies of the Health Belief Model with adults

The Health Belief Model (HBM) relates a socio-psychologic theory of decision making to individual health-related behaviors. We conducted a meta-analysis of the relationships between four HBM dimensions (Susceptibility, Severity, Benefits and Costs) and health behavior on 16 studies that measured all four of the dimensions, measured a behavioral dependent variable and included some measures of reliability, minimal criteria for establishing the validity of the dimensions. Mean effect sizes were computed for all the studies, subgroupings representing studies of screening, risk reduction and adherence to medical regimen, and prospective and retrospective study designs. Of 24 mean effect sizes, 22 were found to be positive and statistically significant. The actual variance accounted for ranged from 0.001 to 0.09. Homogeneity was rejected for 15 of the 22, however, suggesting that the same underlying construct was not measured. Retrospective studies were found to have significantly large effect sizes for benefits and costs and smaller effect sizes for severity when compared to prospective studies. The weak effect sizes and lack of homogeneity indicate that it is premature to draw conclusions about the predictive validity of the HBM as operationalized in these studies. Our finding of only 16 studies meeting minimal criteria for valid representation of the HBM dimensions indicates that future studies should focus more on such issues.

Definition and yield of inclusion criteria for a meta-analysis of patient education studies in clinical preventive services

Because selection of studies for a literature review influences conclusions, inclusion criteria are of utmost importance. For a meta-analysis of studies testing effects of patient education on preventive behaviors, we present the framework and concepts used for setting inclusion criteria for primary studies. We also present the yield in terms of number and distribution of studies that resulted from the inclusion criteria. Because we were interested in a diverse range of behaviors and a broad definition of patient education, we present a method for grouping behaviors by type of behavior change and describe parameters for subgrouping interventions by orientation and communication channel. Of 5,451 citations located and abstracts screened, 561 citations reporting potentially relevant studies were reviewed. Based on our inclusion criteria, 171 citations contained relevant studies, of which 64 studies (found in 62 citations) also met our acceptability criteria. We examine the effects of alternate inclusion criteria on the yield of primary studies and their distributions across the subgroupings.

Identifying pregnant women who drink alcoholic beverages

This randomized 2 x 2 study compared disclosure rates of alcohol use with two response formats (multiple choice and dichotomous) and two communication channels (oral and written) in an adult prenatal population (N = 1078). The multiple choice question improved disclosure, regardless of channel, by 40% across white, African-American, and Hispanic subgroups.

Improving disclosure of smoking by pregnant women

Smoking is a major modifiable risk factor in pregnancy, and low-cost interventions have been developed and tested in diverse populations of pregnant smokers. Successful intervention depends on identification, however, and nondisclosure can be a problem. This randomized study compared rates of disclosure with two response formats--multiple choice, in which the patient is able to describe herself as having "cut down," and the usual history question, "Do you smoke?," in which she is forced to answer simply "yes" or "no". Each format was tested in both oral and written channels with a multiethnic adult prenatal population (n = 1078) entering care in a multispecialty group. Study results indicate that the multiple choice question improved disclosure, regardless of channel (oral versus written), by 40%. This effect was observed across racial and ethnic groups. Biochemical tests of urine samples from reported nonsmokers indicated smoking in only 3%. Eleven percent of the "nonsmokers" in the experimental groups refused consent for the urine test, however, and many of these were probably smokers.

Assessing the congruence between physician behavior and expert opinion in smoking cessation counseling

This study examines the degree of transfer of smoking cessation innovation from research to health care settings by comparing frequency-of-practice ratings by a national sample of family practice physicians (n = 903, response rate = 70%) and importance ratings by smoking cessation and prevention experts (n = 58, response rate = 84%) for 14 counseling techniques. The physician survey elicited a profile that combines traditional and behavioral techniques--discussing smoking with patients, encouraging goal setting, suggesting specific steps for quitting, and presenting pamphlets. They refer to others infrequently and rarely report planning for follow-up about smoking. The experts rated these selected techniques as moderately to highly important. They favored a behavioral approach coupled with active follow-up. The major differences between physician and expert rankings were that the experts placed higher priority on planned follow-up and a lower priority on pamphlets. The uneven quality of counseling reported by physicians suggests that weighting their responses according to expert opinion would provide a more sensitive profile. Scaled weighting produced scores that may help researchers define a composite quality-quantity measure of activity.

Women who stop smoking spontaneously prior to prenatal care and predictors of relapse before delivery

This study explores the experience of pregnant women who quit smoking prior to initiating prenatal care. These "spontaneous quitters" comprised 41% of a socioeconomically and ethnically diverse population of prepregnancy smokers enrolled in a health maintenance organization. Compared to women who were smoking at the start of prenatal care, spontaneous quitters had been lighter smokers, were less likely to have another smoker in their household, indicated a stronger belief in the harmful effect of maternal smoking, had a history of fewer miscarriages, and entered prenatal care earlier. Biochemical validation of smoking status over the course of pregnancy found that 21% of the spontaneous quitters relapsed prior to delivery. Characteristics reported at the first prenatal visit that were associated with maintenance included having achieved cessation for a longer period of time without smoking even a puff, higher self-efficacy for maintenance, stronger belief in the harmful effect of maternal smoking, primigravida, and greater frequency of nausea. The identification of spontaneous quitters and selected intervention for those at greatest risk of relapse is recommended for inclusion in routine prenatal care.

Maintenance of nonsmoking postpartum by women who stopped smoking during pregnancy

This paper describes self-reported maintenance of nonsmoking at six months postpartum by women whose abstinence was verified beginning before the 20th week of pregnancy and continuing through delivery (n = 134). The overall maintenance rate of 37 percent was not related to sociodemographic characteristics, smoking and obstetric history, the time when quitting occurred, or a prenatal smoking cessation program. Although this rate is encouraging, more attention should be directed to sustaining prenatal abstinence from smoking beyond delivery.

Identifying families at high risk of cardiovascular disease: alternative work site approaches

By examining coverage, concordance, and costs, this project evaluated four methods of cardiovascular disease (CVD) risk screening at a work site with 1821 central office employees of an energy company in Houston, Tex. Screening methods included a health risk appraisal mail questionnaire (HRA), an HRA plus brief physical assessment, an analysis of medical claims data, and an analysis of absenteeism data. Coverage ranged from 99% of employees for the absenteeism method to about 30% for the HRA method. Combining the first three screening methods, 18% of families had at least one member with a CVD or related diagnosis or one of four major CVD risk factors. The absenteeism method yielded 12.1% of the central office employees with 9 or more days absent. Although the absenteeism method identified high-cost families, only 9% had a heart disease or related diagnosis. This lack of concordance also occurs with other methods. For example, only 9.4% of families identified with the claims data were also identified by the HRA. Therefore, the methods identify different groups of high-risk families. Findings are discussed in relation to costs and other factors important to firms' selection of screening methods.

Selected predictors of health promotion counseling by three groups of allied health professionals

Three groups of allied health professionals, including dental hygienists, dietitians, and certified nurse-midwives, were surveyed to determine current practice, beliefs, and attitudes regarding health promotion and disease prevention. The study aimed to explore the power of selected variables drawn from social learning theory in predicting self-reported level of counseling. We conducted separate analyses for 10 areas of health promotion and disease prevention: high blood pressure, smoking, lack of exercise, overweight, high-fat diet, alcohol abuse, illicit drug use, stress, isolation and loneliness, and nonuse of safety belts. The predictor variables were respondents' professional group membership, confidence that they possess appropriate skills and knowledge to counsel patients (self-efficacy), belief that patients will follow through on recommendations (adherence expectation), and belief that reduction of risk will improve patients' health status (expectation of health impact). The level of counseling activity varied markedly across the risk areas, with blood pressure and weight receiving the most emphasis on average and isolation and loneliness and nonuse of safety belts receiving markedly less attention. There also was variation across the professional groups. Certified nurse-midwives had higher mean counseling scores in all topics except those related to diet, where the dietitians' mean scores were approximately the same. Of all the areas about which counseling might be increased, use of safety belts stands out as having the lowest reported prevalence, the least complexity in terms of implementation, and the most relevance to at least two of the professional groups. These findings suggest the importance of skills training, including the provision of actual or simulated counseling experience and modeling by others in the same professional group.(ABSTRACT TRUNCATED AT 250 WORDS)

Pregnancy and medical cost outcomes of a self-help prenatal smoking cessation program in a HMO

The results of a randomized clinical trial of a prenatal self-help smoking cessation program are reported in terms of the pregnancy and cost outcomes. The study population were the socioeconomically and ethnically diverse members of a large health maintenance organization (HMO) who reported that they were smoking at the time of their first prenatal visit. The intervention consisted predominantly of printed materials received through the mail. Compared with the usual care control group, women assigned to the self-help program were more likely to achieve cessation for the majority of their pregnancy (22.2 percent versus 8.6 percent), gave birth to infants weighing on average 57 grams more, and were 45 percent less likely to deliver a low birth weight infant. An economic evaluation of the self-help program was conducted from the perspective of the sponsoring HMO. Based upon the expenditures associated with the neonates' initial hospital episode, the intervention had a benefit-cost ratio of 2.8:1. These findings provide strong evidence to support widespread incorporation of smoking cessation interventions as a standard component of prenatal care.

Cardiovascular mortality trends in Harris County, Texas: 1980 to 1986

Cardiovascular diseases are the leading causes of death in Texas and in the United States. This study determines the trend in mortality rates attributed to cardiovascular diseases in Harris County from 1980 to 1986. The region of the county that does not include the City of Houston was specifically studied. Mortality of cardiovascular diseases in these two areas follow patterns similar to that of the United States in the same time period. Both the entire county and Harris County excluding Houston show declines in cardiovascular mortality rates in the 7-year period. The populations were divided into four ethnic categories (white, black, Hispanic and "other"), and each ethnic group reported significant declines in overall cardiovascular mortality except in the "other" population, which showed an increase in the male group. Significant downward trends were noticed in the white and Hispanic population in the two major subcategories of cardiovascular diseases: diseases of the heart and cerebrovascular diseases. The black population in each geographic area studied was consistently higher in cardiovascular mortality than the other three ethnic groups observed (white, Hispanic and "other"). Knowledge of cardiovascular disease mortality rates by ethnicity, sex, and age as well as temporal changes in mortality rates within Harris County are important for health planners in continuing and implementing programs aimed at awareness, prevention, and treatment of cardiovascular diseases.

Patterns of counseling techniques used by family practice physicians for smoking, weight, exercise, and stress

Members of the American Academy of Family Physicians (nonfederal, continental U.S.) were surveyed regarding their involvement in health-habit modification (response rate = 70.4%, n = 903). Frequency and indications for use of specific counseling techniques were assessed in each of four health-habit areas: smoking, exercise, weight control, and stress management. Factor analysis of responses produced clusters of techniques labeled "traditional teaching," "behavioral," "interpersonal with follow-up," and "referral." The dominant style varied by health-habit area. The factors were less clear for stress than for the other three areas. Results indicated no relationships or weak relationships between counseling approaches and physician gender, year of graduation, board status, region, community size, practice type, average visit length, and selected patient characteristics. Study findings suggest that family physician counseling varies with the health habit and that background and practice variables are not associated with counseling approach.

Assessing the quality of health promotion and patient education programs

Quality assessment for health promotion and patient education programs helps ensure that these services are efficient and effective, and represent professional standards of practice. It also helps ensure that they are beneficial, accessible, and acceptable to members. Three program characteristics should be considered in defining the objectives of an assessment--the degree of existing knowledge regarding the effectiveness of the program, the degree of risk posed by the program, and the cost of the program. A menu of objective is presented, including assessment of the structure of the program; comparison of the program with state-of-the-art models; assessment of program implementation and coverage; measurement of member/patient response; evaluation of program outcome; and evaluation of cost-effectiveness, opportunity costs, and broad benefits to the organization. Major methods for assessment and evaluation are discussed briefly in relationship to the objectives they address--review of professional staff performance; comparison with models, standards, and other criteria; documentation and management information systems; focus groups and other small-scale qualitative methods; participation in plan monitoring and quality assurance activities; and controlled evaluation studies.

A randomized trial of a serialized self-help smoking cessation program for pregnant women in an HMO

We report the results of a population-based randomized clinical trial that tested the effectiveness of a prenatal self-help smoking cessation program. The intervention consisted predominantly of printed materials received through the mail. The population (n = 242) consisted of a socioeconomically and ethnically diverse group of pregnant women enrolled in a large health maintenance organization (HMO) who reported they were smoking at the time of their first prenatal visit. Biochemical confirmation of continuous abstinence achieved prior to the 20th completed week of pregnancy and lasting through delivery revealed 22.2 per cent of the women in the eight-week serialized program quit versus 8.6 per cent of controls with usual care. The adjusted odds ratio was 2.80 (95 per cent CI = 1.17, 6.69). We conclude that a low-cost prenatal self-help intervention can significantly affect the public health problem of smoking during pregnancy and its associated risks for maternal and child health.

Health beliefs and behaviors of physician assistants in Texas: implications for practice and education

Concern has been expressed over how the volume and effectiveness of physicians' practices relative to prevention can be increased. While a review of the health care services provided by physician assistants in medical practices indicated an emphasis on health education and patient counseling, there has existed an absence of data regarding their beliefs and practices in the area of health promotion. Based upon an analysis of self-reported data from 256 respondents (89%) of a random sample (n = 289) of the 870 physician assistants in Texas, it appears that physician assistants perceive themselves as having a role in health promotion, are generally satisfied with their preventive health care role, view health promotion activities as being more important in the future, and disagree with the idea that health promotion would not be well received by patients. They routinely gather information on health behaviors and discuss or recommend ways to reduce at-risk behavior. Furthermore, while expressing certainty about their knowledge and skills to educate and influence individuals to change certain risk behaviors, physician assistants indicate less certainty about patient follow-through when it relates to such activities as smoking, drinking, and the use of illicit drugs. Considering the perceived challenge and the view that health promotion will become an even larger component of the physician assistant's future role, these findings suggest a need for additional skills training to better assist patients to modify their more complex health risk behaviors.

Health promotion and patient education benefits for employees

One step that employers can take to assure that employees receive such education services is pursuing coverage of education as a separate service. For some time now, insurers have shown interest in patient education services (15-17, 61), but patient education "integral to care" is typically covered only as a part of the "per diem" in the case of hospitals or as part of the visit fee in the case of outpatient visits. Education for patients with diabetes is being covered experimentally as a separate service in at least 17 states. Physicians whose practice is composed largely of "cognitive services" rather than "procedures" are also interested in education as a reimbursable service. The same arguments as described in relation to coverage of risk reduction services generally apply to this case. Education programs for employees who are under medical care can improve their adherence to the recommended regimen and hence can improve the effectiveness of care. Education and counseling prior to surgical and other stressful procedures decrease stress and the need for pain medications, and they can shorten the length of hospital stays. Education is an important component of programs to substitute home care for hospital care or expensive outpatient care. Currently, however, a patient cannot rely on usual providers of medical care to offer adequate education. Reimbursement for patient education on a selected, experimental basis is probably warranted for chronic conditions requiring complex adjustments and regimens. Cases of asthma where there is a history of hospitalization or emergency room visits is an excellent possibility. The experience of covering diabetes education should be monitored to help resolve the debate.

Selected allied health professionals' self-confidence in health promotion counseling skills and interest in continuing education programs

Mail surveys of samples of dental hygienists (n = 90, 36% response), registered dietitians (n = 262, 52% response), and physician assistants (n = 289, 89% response) in Texas and certified nurse midwives (n = 143, 57% response) in the US provided data regarding their confidence that they possess skills and knowledge to counsel patients about selected areas of health promotion (self-efficacy). Also, the surveys gathered information regarding respondents' beliefs that patients will follow through on their recommendations (adherence expectation), and their interest in continuing education programs. Overall, respondents displayed highest self-efficacy with regard to counseling patients about blood pressure and smoking. Confidence was lowest in illicit drug abuse and mental health areas. Certified nurse midwives and physician assistants indicated confidence in many more areas than the other two groups. Respondents consistently expressed less certainty about patient adherence than about their own skills and knowledge. They generally indicated a high degree of interest in continuing education across the several health promotion topics. Modest relationships were observed between self-efficacy and interest in continuing education programs for physician assistants and registered dietitians, indicating that those with greater self-efficacy had a greater interest in building their skills. A similar pattern was observed among physician assistant respondents with respect to adherence expectations.

Predictors of safety belt initiative by primary care physicians. A social learning theory perspective

Even with the passage of state safety belt laws, primary care physicians can contribute to their patients' safety by brief interventions. The present study explores the prevalence of such action with adult patients and tests the power of constructs taken from social learning theory to explain physicians' behavior. These constructs included self-efficacy, personal behavior (self-modeling) and three outcome expectations--expectation of patient follow-through, health impact, and impact of health promotion on the practice. Data were taken from a survey of Texas family physicians prior to enactment of the state law (n = 209). History-taking and advising were combined to form a single scale, "safety belt action." Prevalence of safety belt action was low. Overall, only 5% said they ask routinely about safety belts; 58.1% do not advise or discuss the risk even when they are aware of nonuse. Social learning theory variables accounted for 34% of the variance in safety-belt action after controlling for year of graduation in a hierarchical regression analysis. Self-efficacy was entered first, and it predicted 25% of the variance. The other social learning variables were entered together, and they predicted the additional 9% of the variance after controlling for year of graduation and self-efficacy. Of these other variables, only health impact was significant, however. These findings suggest several avenues for improving safety belt action and add evidence for the importance of outcome expectations over and above self-efficacy.

Stress management in primary care: physicians' beliefs and patterns of practice

We examined attitudes and practices related to stress management in a random sample of Texas primary care physicians. Two fifths of the physicians indicated that avoiding undue stress was very important, and more than one third reported that they gathered information about stress on a routine basis. Over two thirds of the physicians said that they had counseled their patients regarding stress and 13 percent had referred patients with high stress to outside programs. The physicians' confidence that they had the skills to help patients with high stress, their belief in the benefits of avoiding undue stress, and their estimate of patient follow-through on recommendations were positively associated with history-taking and counseling regarding stress. Recommendations for medical education include incorporating information about stress and health into medical school curriculums, building skills in stress management, and increasing feedback from patients who have coped successfully with high stress.

Efficacy of psychoeducational interventions on pain, depression, and disability in people with arthritis: a meta-analysis

Meta-analysis is a technique which combines data from several properly and similarly designed controlled studies so as to increase the power of the relevant statistical analysis. Fifteen studies on the effects of psychoeducational interventions on disability, pain and depression in individuals with chronic rheumatoid arthritis or osteoarthritis were analyzed by this method. The results indicate that patient education can indeed contribute to improving the health status of such patients.

The cost effectiveness of an education outreach representative to OB practitioners to promote smoking cessation counseling

Growing concern about mothers, smoking during pregnancy calls for effective patient education by health care professionals. Because most women receive prenatal care and people with high perceived self-risk do have high cessation rates when advised by physicians, prenatal care in private practice offers a unique opportunity to decrease the number of pregnant women who smoke. The pilot test described here is a one-group pretest and posttest community trial which tested the feasibility of using an education outreach representative to market smoking- and pregnancy-education materials to private practice physicians. The costs of the pilot test are compared to the costs of three other strategies for disseminating education materials. The pilot test proved more cost-effective than two direct-mail strategies and one commercial enterprise. These results suggest that this strategy is feasible and merits further study for distributing education materials and teaching effective education strategies to physicians.

Health promotion and disease prevention beliefs and behaviors of dietetic practitioners

Fifty-three percent of a random sample of 500 members of the Texas Dietetic Association responded to a survey designed to determine their personal health behavior, beliefs, and patient counseling practices related to health promotion and disease prevention. This article reports the responses of the 180 practitioners involved in direct patient care in order to depict the health promotion/disease prevention beliefs and behaviors of that particular group. Health habits (e.g., smoking, physical activity, and dietary patterns) of dietetic practitioners were better than those of the general female population. Personal health habits related to not smoking and to getting regular exercise were significantly associated with belief in the importance of that behavior for others. Although most of the dietetic practitioners indicated that the identified health behaviors were important to the health of the average person, only a few practitioners gave them routine attention in their practice. Respondents generally expressed a lack of confidence in their ability to educate clients about specified health behaviors, with the exception of weight control, high-fat diets, elevated blood pressure, and exercise patterns. The practitioners' confidence in their counseling skills was significantly correlated with intensity of counseling (p less than or equal to .001) and the likelihood of client compliance, except in the area of weight control. The majority of the dietitians strongly agreed that health promotion will be more important in the future.
