Health education for pregnant smokers: its behavioral impact and cost benefit.

OBJECTIVES: A randomized trial (the Birmingham Trial II) was conducted to evaluate the behavioral impact of health education methods among 814 female smokers at four public health maternity clinics. METHODS: Four hundred patients were randomly assigned to an Experimental (E) Group, and 414 were assigned to a Control (C) Group. Self-reports and saliva cotinine tests confirmed smoking status at the first visit, at midpregnancy, and at end of pregnancy. RESULTS: The E Group exhibited a 14.3% quit rate and the C Group an 8.5% quit rate. A Historical Comparison (C) Group exhibited a 3.0% quit rate. Black E and C Group patients had higher quit rates than White E and C Group patients. A cost-benefit analysis found cost-to-benefit ratios of $1:$6.72 (low estimate) and $1:$17.18 (high estimate) and an estimated savings of $247,296 (low estimate) and $699,240 (high estimate). CONCLUSION: Health education methods are efficacious and cost beneficial for pregnant smokers in public health maternity clinics.

Characteristics and correlates of asthma in a university clinic population.

To contribute more comprehensive information about the characteristics of asthma, this article analyzed patients served by the University of Alabama at Birmingham Comprehensive Asthma Program. Their physicians rated one fifth of these patients as having "severe" asthma with the remainder about equally divided between "moderate" and "mild". One in two first received a diagnosis of asthma ten or more years previously. Common comorbidities were hypertension, obesity, rhinitis, bronchitis, sinusitis, and arthritis. One half had visited an emergency room or been hospitalized for asthma in the past year. Inhaled bronchodilators and continuous theophylline were the most commonly prescribed medications. Side effects, especially tachycardia and insomnia, were common and almost exclusively associated with theophylline or corticosteroid therapy. Spirometric assessment showed chronic airflow obstruction in those with more severe asthma. Prevalence of respiratory symptoms, intensity of medication regimen, incidence of side effects, and health care utilization increased as asthma severity increased.

Evaluation of the efficacy and cost effectiveness of health education methods to increase medication adherence among adults with asthma.

We randomized 135 adult asthma patients to a control group, and 132 patients to an experimental group which received a special health education intervention. Four adherence measures were documented at baseline and 12-month follow-up: correct inhaler use, inhaler adherence, medication adherence, and total adherence rating. Costs to routinely deliver the intervention were $32.03/patient. Experimental group patients exhibited a significantly higher level of improvement in adherence (44 percent) than control group patients (2 percent).

A randomized trial to improve self-management practices of adults with asthma.

The prevalence and impact of adult asthma are substantial, and poor self-management practices, especially failures to adhere to treatment regimens, appear to be a significant problem. Desirable characteristics of an intervention program to improve self-management were identified through needs assessment and review of existing patient education resources. A comprehensive program was developed that integrated a workbook with one-to-one counseling and adherence-enhancing strategies. A longitudinal 1-year study compared patients receiving this self-management program with "usual care" patients receiving standard asthma pamphlets. Patients were randomly assigned to conditions. Baseline score and asthma severity were statistically controlled. Self-management patients had substantially better adherence than usual care patients, as well as improved functional status, at follow-up. Hospital and emergency department visits decreased in both groups but did not differ between groups.

Patient characteristics relevant to effective self-management: scales for assessing attitudes of adults toward asthma.

The Asthma Opinion Survey, a 33-item Likert-type instrument, was designed to measure attitudes relevant to self-management in adult outpatients. Items fall into eleven clusters; General Vulnerability, Specific Vulnerability, Attitudes Toward Patient Knowledge, Recognition of Airway Obstruction, Accessibility of Health Care, Panic-Fear, Belief in Treatment Efficacy, Staff-Patient Relationships, Sense of Control, Personal Impact, and Social Impact. Factor analysis of the clusters yielded three factors Vulnerability, Perceived Quality of Care, and Recognition and Control. The items, clusters, and factors all had adequate to good score spreads and internal consistencies. Asthma opinions covaried significantly with demographic characteristics, asthma severity, and intensity of health care utilization, and correlated with the Asthma Symptoms Checklist, an instrument developed at the National Jewish Hospital-National Asthma Center, in ways supporting construct validity. These results suggest the Asthma Opinion Survey is achieving its intended purpose.

Assessing the use of metered dose inhalers by adults with asthma.

The development and analysis of an instrument to evaluate the use of metered dose inhalers by patients in the University of Alabama at Birmingham (UAB) Asthma Program is presented. A total of 238 adult asthma patients demonstrated use of the metered dose inhaler for this analysis. Patient skill in using the inhaler was recorded using the instrument, Inhaler-Use Checklist, developed at UAB. The study found that most patients use metered dose inhalers incorrectly, despite training received from their physicians on proper use of inhalers.

The effectiveness of a worksite self-help smoking cessation program: a randomized trial.

A 2 x 2 randomized, factorial pretest/posttest group design was used to evaluate the effectiveness of self-help smoking cessation methods at the worksite. The study investigated the effect of a multicomponent health education and skill intervention versus the effect of a monetary incentive to the employee for quitting. All employees received, in addition, a standardized self-help smoking cessation manual and maintenance manual. Following agreement to participate and a baseline smoking history, all participants were followed for 6 weeks, 6 months, and 12 months. Saliva was obtained for thiocyanate (SCN) analysis of smoking status. Of the estimated 2000 smokers at the site, 387 smokers were recruited. Employees were randomly assigned to one of four groups. Results of this random trial indicate that those employees receiving a multicomponent program were most successful in quitting and remaining abstinent. The monetary incentive appears to have no effect on quit rate.

Some simple scales for use in asthma research.

Several reviewers have recently identified a need for systematic efforts to improve the quality of questionnaires and other measures used in asthma research. This article applies standard psychometric techniques to scales developed to help meet this need. These scales assess asthma symptoms, respiratory diseases, the extent to which asthma inconveniences patients, medication regimens, and medication side effects. Scale quality was assessed by using data from 262 adult asthma patients. The results in general support the usefulness of these scales. The reliabilities indicate an acceptable to good level of internal consistency; the spread of scores is good; and correlations with external variables support validity.

Effectiveness of impersonal versus interpersonal methods to recruit employees into a worksite quit smoking program.

One of the first salient issues a worksite quit smoking program must face is how to motivate employees to enroll and participate. The purpose of this study was to determine the effectiveness of impersonal versus interpersonal recruitment strategies used by an ongoing worksite quit smoking program. One hundred and nineteen smokers who stated on a questionnaire that they would be either "strongly yes" or "yes" interested in participating in a quit smoking program were randomized into two groups. One group was sent letters by employee mail from the director of the quit smoking program. This letter briefly described the program and invited employees to participate. The other group received a personal phone call from the staff health educator inviting them to participate. Results indicate that of the 46 individuals randomly assigned to Group 1 who were sent letters, none responded to the invitation; while 37 of the 44 employees who received a personal phone call, 19 scheduled an appointment, 7 kept their appointments. These results indicate the possible increased effectiveness of an impersonal versus interpersonal communications in recruiting full-time smoking employees.

Promoting self-management in adults with asthma: an overview of the UAB program.

Most asthma self-management programs have focused on children, but the prevalence and impact, both personal and economic, of adult asthma is substantial. Moreover, failure to adhere to treatment regimens appears to be a significant problem in adult asthma. It appears important, therefore, to develop asthma self-management programs for adults. The UAB program is based on the Health Belief Model for health behavior and on the PRECEDE Model for patient education. A needs assessment and a review of existing educational materials were used to specify the content of a self-care workbook. This workbook seeks to increase cognitive skills, encourage daily self-assessment of asthma, demonstrate success in asthma self-management, and promote effective social support. The overall intervention integrates this workbook with systematic reinforcement of self-monitoring and self-management. A prospective controlled study is comparing patients receiving this "special intervention" with "usual care" patients who receive only routinely available pamphlets providing information about asthma. Patients are randomly assigned to treatments by the closed envelope technique. Sample sizes were determined on the basis of statistical power. Outcomes in five areas are assessed: (1) health care utilization, (2) functional status, (3) knowledge, (4) adherence, and (5) psychological reactions.

Guidelines and methodological standards for smoking cessation intervention research among pregnant women: improving the science and art.

While the evidence confirming the risks of smoking during pregnancy is unequivocal, smoking rates for U.S. women remain high. From 1965 to 1975 the proportion of women smokers, aged 18 to 35, rose from 34% to 36%. Rates of heavy smoking increased from 51% to 61%. Significant increases were noted in the United States, especially for teenaged girls, with 1979 data showing higher smoking rates among girls aged 17 to 18 (26%), than among the same-aged boys (19%). Moreover, adolescents have one-fifth of all U.S. births. Exact rates of smoking during pregnancy are unknown but several reports suggest 20-40% of pregnant U.S. women smoke at the onset of pregnancy. A national survey showed 35% of young women smokers able to quit smoking during pregnancy, with another 32% cutting down. Although 62% believed that smoking could harm the fetus, the majority were unable to stop smoking during their pregnancy. Most women who succeed in quitting or cutting down revert to their usual smoking habits late in pregnancy or after delivery. Since almost all data are based on self-reports, some degree of inaccuracy and underreporting can be assumed.

Use of a bogus pipeline method to increase accuracy of self-reported alcohol consumption among pregnant women.

Pregnant women (N = 220) attending urban maternity care clinics were randomly assigned to study groups to determine the effectiveness of a "bogus pipeline" method to increase the accuracy of behavioral self-reports of alcohol consumption. Results indicate a significant difference (p less than .025) between those who reported alcohol consumption and those who were told their behavioral self-report of alcohol consumption would be confirmed by a physiological test (bogus pipeline). Only 14% in the self-reported group said they currently used alcohol during pregnancy, whereas 27% in the bogus pipeline group reported consumption of alcohol during pregnancy. The results suggest that the use of the bogus pipeline may increase the accuracy of self-reported alcohol consumption data from a cohort of pregnant women.

Health education and medicine: competition or cooperation?

Shifts in the expectations of the public, in the practice of medicine, and in the state of the art of health education call for an examination of the nature of the relationship between the health education and medical professions. Their relationship can be characterized in terms of competition or cooperation. This paper examines a number of issues related to these shifts and discusses the potential and pitfalls of this relationship. It is concluded that power is a fundamental issue to be recognized and addressed by health education specialists.

The effectiveness of smoking cessation methods for smokers in public health maternity clinics: a randomized trial.

Little insight is available in the literature on how best to assist the pregnant smoker in public health maternity clinics to quit during pregnancy. A randomized pretest/posttest experiment was used to evaluate the effectiveness of two different self-help cessation methods. Three hundred and nine pregnant women from three public health maternity clinics were assigned randomly to one of three groups with one-third assigned to each: a control group; a group receiving the American Lung Association's Freedom From Smoking Manual; and those receiving A Pregnant Woman's Self-Help Guide to Quit Smoking. Using a saliva thiocyanate (SCN) and behavioral report at mid-pregnancy and end of pregnancy to confirm cessation or reduction, 2 per cent in the control group quit and 7 per cent reduced their SCN levels substantially. Of the women assigned to the ALA method, 6 per cent quit and 14 per cent reduced their SCN levels substantially. Of the women who used the Guide, 14 per cent quit and 17 per cent reduced their SCN levels substantially. Results of this trial indicate that health education methods tailored to the pregnant smoker are more effective in changing smoking behavior than the standard clinic information and advice to quit and/or the use of smoking cessation methods not tailored to the needs of the pregnant smoker.
