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

Adherence to Pulmonary Rehabilitation in COPD: A QUALITATIVE EXPLORATION OF PATIENT PERSPECTIVES ON BARRIERS AND FACILITATORS

PURPOSE

Adherence to pulmonary rehabilitation (PR) is low. This qualitative study used the PRECEDE model to identify predisposing (intrapersonal), reinforcing (interpersonal), and enabling (structural) factors acting as barriers or facilitators of adherence to PR, and elicit recommendations for solutions from patients with chronic obstructive pulmonary disease (COPD).

METHODS

Focus groups with COPD patients who had attended PR in the past year were conducted. Sessions were recorded, transcribed verbatim, and coded independently by 2 coders, who then jointly decided on the final coding scheme. Data were summarized across groups, and analysis was used a thematic approach with constant comparative method to generate categories.

RESULTS

Five focus groups with 24 participants each were conducted. Participants (mean age 62 yr) were 54% male, and 67% black. More than half had annual income less than $20 000, 17% were current smokers, and 54% had low adherence (less than 35% of prescribed PR sessions). The most prominent barriers included physical ailments and lack of motivation (intrapersonal), no support system (interpersonal), transportation difficulties, and financial burden (structural). The most prominent facilitators included health improvement, personal determination (intrapersonal), support from peers, family, and friends (interpersonal), and program features such as friendly staff and educational component of sessions (structural). Proposed solutions included incentives to maintain motivation, tobacco cessation support (intrapersonal), educating the entire family (interpersonal), transportation assistance, flexible program scheduling, and financial assistance (structural).

CONCLUSION

Health limitations, social support, transportation and financial difficulties, and program features impact ability of patients to attend PR. Interventions addressing these interpersonal, intrapersonal, and structural barriers are needed to facilitate adherence to PR.

Tobacco smoke exposure in pediatric cystic fibrosis: A qualitative study of clinician and caregiver perspectives on smoking cessation

OBJECTIVE

Tobacco smoke exposure has negative impacts on the lung health of children with cystic fibrosis (CF), yet evidence-based strategies for smoking cessation have not been tested with or tailored to CF caregivers. This qualitative study identified barriers and facilitators of smoking cessation in this population and outlined potential interventional approaches.

METHODS

We conducted semi-structured interviews with CF familial caregivers who were current or former smokers, and with members of the CF care team. We asked about experiences, practices, and prerequisites for a successful program. Interviews were recorded, transcribed verbatim, and coded by two investigators. Analysis used a thematic approach guided by the PRECEDE model, which identifies predisposing (intrapersonal), reinforcing (interpersonal), and enabling (structural) factors relevant to health behaviors and programs.

RESULTS

Seventeen interviews were conducted-eight with familial caregivers and nine with CF team members. Whereas caregivers provided greater insight into internal difficulties and motivators to quit smoking, clinicians offered more extensive input on barriers and solutions related to the clinical environment. Based on study recommendations, a successful tobacco cessation program should include (a) family education about the harms of smoke exposure for children with CF; (b) screening for exposure, ideally with biochemical verification; (c) access to trained tobacco counselors; (d) affordable pharmacotherapy; and (e) outpatient follow-up of those undergoing tobacco treatment.

CONCLUSION

This qualitative study revealed intrapersonal, interpersonal, and structural barriers to eliminating tobacco smoke exposure in children with CF, outlined opportunities to address these barriers, and made recommendations for a comprehensive tobacco cessation strategy.

Cognitive behavioural therapy (CBT) for adults and adolescents with asthma

BACKGROUND

People with asthma have a higher prevalence of anxiety and depression than the general population. This is associated with poorer asthma control, medication adherence, and health outcomes. Cognitive behavioural therapy (CBT) may be a way to improve the quality of life of people with asthma by addressing associated psychological issues, which may lead to a lower risk of exacerbations and better asthma control.

OBJECTIVES

To assess the efficacy of CBT for asthma compared with usual care.

SEARCH METHODS

We searched the Cochrane Airways Group Specialised Register, ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP). We also searched reference lists of all primary studies and review articles and contacted authors for unpublished data. The most recent searches were conducted in August 2016.

SELECTION CRITERIA

We included parallel randomised controlled trials (RCTs) comparing any cognitive behavioural intervention to usual care or no intervention. We included studies of adults or adolescents with asthma, with or without comorbid anxiety or depression. We included studies reported as full text, those published as abstract only, and unpublished data.

DATA COLLECTION AND ANALYSIS

Two or more review authors independently screened the search results, extracted data, and assessed included studies for risk of bias. We analysed dichotomous data as odds ratios (ORs) and continuous data as mean differences (MDs) or standardised mean differences (SMD) where scales varied across studies, all using a random-effects model. The primary outcomes were asthma-related quality of life and exacerbations requiring at least a course of oral steroids. We rated all outcomes using GRADE and presented our confidence in the results in a 'Summary of findings' table.

MAIN RESULTS

We included nine RCTs involving 407 adults with asthma in this review; no studies included adolescents under 18. Study size ranged from 10 to 94 (median 40), and mean age ranged from 39 to 53. Study populations generally had persistent asthma, but severity and diagnostic measures varied. Three studies recruited participants with psychological symptomatology, although with different criteria. Interventions ranged from 4 to 15 sessions, and primary measurements were taken at a mean of 3 months (range 1.2 to 12 months).Participants given CBT had improved scores on the Asthma Quality of Life Questionnaire (AQLQ) (MD 0.55, 95% confidence interval (CI) 0.17 to 0.93; participants = 214; studies = 6; I2 = 53%) and on measures of asthma control (SMD -0.98, 95% CI -1.76 to -0.20; participants = 95; studies = 3; I2 = 68%) compared to people getting usual care. The AQLQ effect appeared to be sustained up to a year after treatment, but due to its low quality this evidence must be interpreted with caution. As asthma exacerbations requiring at least a course of oral steroids were not consistently reported, we could not perform a meta-analysis.Anxiety scores were difficult to pool but showed a benefit of CBT compared with usual care (SMD -0.38, 95% CI -0.73 to -0.03), although this depended on the analysis used. The confidence intervals for the effect on depression scales included no difference between CBT and usual care when measured as change from baseline (SMD -0.33, 95% CI -0.70 to 0.05) or endpoint scores (SMD -0.41, 95% CI -0.87 to 0.05); the same was true for medication adherence (MD -1.40, 95% CI -2.94 to 0.14; participants = 23; studies = 1; I2 = 0%).Subgroup analyses conducted on the AQLQ outcome did not suggest a clear difference between individual and group CBT, baseline psychological status, or CBT model. The small number of studies and the variation between their designs, populations, and other intervention characteristics limited the conclusions that could be drawn about these possibly moderating factors.The inability to blind participants and investigators to group allocation introduced significant potential bias, and overall we had low confidence in the evidence.

AUTHORS' CONCLUSIONS

For adults with persistent asthma, CBT may improve quality of life, asthma control, and anxiety levels compared with usual care. Risks of bias, imprecision of effects, and inconsistency between results reduced our confidence in the results to low, and evidence was lacking regarding the effect of CBT on asthma exacerbations, unscheduled contacts, depression, and medication adherence. There was much variation between studies in how CBT was delivered and what constituted usual care, meaning the most optimal method of CBT delivery, format, and target population requires further investigation. There is currently no evidence for the use of CBT in adolescents with asthma.

Self-Management of Chronic Disease by Older Adults

This article summarizes the literature describing the at-home management of and psychosocial coping with five chronic diseases (heart disease, asthma, chronic obstructive pulmonary disease, arthritis, and diabetes) by the general population of adults. It also reviews the literature describing self-management of these chronic diseases by older adults. Conclusions drawn subsequent to the review are (a) that there are strong commonalities in the essential nature of tasks that exist across disease entities, (b) that the context for self-management of disease by the ill elderly is likely to differ somewhat from the context for other age groups. Questions for future research are posed.

WITHDRAWN: Written individualised management plans for asthma in children and adults

BACKGROUND

Non-adherence to treatment advice is a common phenomenon in asthma and may account for a significant proportion of the morbidity. Comprehensive care that includes asthma education, a written self-management plan and regular review has been shown to improve asthma outcomes, but the contribution of these components has not been established.

OBJECTIVES

To determine whether the provision of a written asthma self-management plan increases adherence and improves outcome.

SEARCH STRATEGY

We carried out a search on the Cochrane Airways Group trials register. There was no language restriction. The search of the databases used the following terms: action plan OR self OR self-care OR self-manag* OR educ* AND adher* OR comply OR compli*. We contacted authors of included studies for any unpublished or on-going studies and bibliographies of all included studies and reviews were searched for further studies. The most recent search was carried out in June 2004.

SELECTION CRITERIA

We only considered randomised controlled trials (RCTs) in patients with asthma. Participants must have been assigned to receive an individualised written asthma management plan (symptom or peak flow based) about the actions required for regular asthma management and/or the actions to take in the event of an asthma exacerbation.

DATA COLLECTION AND ANALYSIS

Two reviewers independently assessed study quality and abstracted data.

MAIN RESULTS

Seven trials met the inclusion criteria. The written management plans were either peak flow or symptom based, which were compared against each other or compared to no written management plan. Reported outcomes included: medication adherence, hospitalisation, emergency department visits, oral corticosteroid use, lung function, days lost from school/work, unscheduled doctor visits and respiratory tract infections. There was no consistent evidence that written plans produced better patient outcomes than no written plan. For some outcomes, there appeared to be an advantage of one type of plan over the other, but there was no consistency - one type of plan was not consistently more effective than another.

AUTHORS' CONCLUSIONS

The available trials are too small and the results too few and inconsistent to form any firm conclusions as to the contribution of written self management plans in the known beneficial effects of a comprehensive asthma care programme.

Options for self-management education for adults with asthma

BACKGROUND

Asthma education and self-management are key recommendations of asthma management guidelines because they improve health outcomes. There are several different modalities for the delivery of asthma self-management education.

OBJECTIVES

We evaluated programmes that: 1) Optimised asthma control through inhaled corticosteroid use by regular medical review or optimised asthma control by individualised written action plans 2) Used written self-management plans based on peak expiratory flow self-monitoring compared with symptom self-monitoring 3) Compared different options for the delivery of optimal self-management programmes.

SEARCH STRATEGY

We searched the Cochrane Airways Group trials register and reference lists of articles.

SELECTION CRITERIA

Randomised trials of asthma self-management education interventions in adults over 16 years of age with asthma.

DATA COLLECTION AND ANALYSIS

Fifteen trials met the inclusion criteria. Trial quality was assessed and data were extracted independently by two reviewers. Study authors were contacted for confirmation.

MAIN RESULTS

1) Six studies compared optimal self-management allowing self-adjustment of medications according to an individualised written action plan to adjustment of medications by a doctor. These two styles of asthma management gave equivalent effects for hospitalisation, ER visits, unscheduled doctor visits and nocturnal asthma. 2) Self-management using a written action plan based on PEF was found to be equivalent to self-management using a symptoms based written action plan in the six studies which compared these interventions. 3) Three studies compared self-management options. In one, that provided optimal therapy but tested the omission of regular review, the latter was associated with more health centre visits and sickness days. In another, comparing high and low intensity education, the latter was associated with more unscheduled doctor visits. In a third, no difference in health care utilisation or lung function was reported between verbal instruction and written action plans.

REVIEWER'S CONCLUSIONS

Optimal self-management allowing for optimisation of asthma control by adjustment of medications may be conducted by either self-adjustment with the aid of a written action plan or by regular medical review. Individualised written action plans based on peak expiratory flow are equivalent to action plans based on symptoms. Reducing the intensity of self-management education or level of clinical review may reduce its effectiveness.

Self-management approaches for people with chronic conditions: a review

The purpose of this paper is to provide an overview of self-management approaches for people with chronic conditions. The literature reviewed was assessed in terms of the nature of the self-management approach and the effectiveness. Findings are discussed under the headings of: chronic conditions targeted, country where intervention was based, type of approach (e.g. format, content, tutor, setting), outcomes and effectiveness. The last of these focused on reports of randomised controlled studies.

Leukotrienes: new therapies and their influence on asthma

Leukotriene receptor antagonists (LTRAs) are new therapies in asthma management which act to block the naturally occurring leukotrienes and improve lung function. It is clear from past research that many asthmatics dislike taking both oral and inhaled steroids and may probably welcome these new drugs simply because they are not steroid preparations. The oral route of LTRAs may be helpful for particular groups of patients, although LTRAs will not be suitable for all asthmatics. Their use so far has been largely as 'add-on' therapies for mild-to-moderate asthma with results that are promising in some patients but have been disappointing in others. Fewer side-effects may well improve medication compliance which has caused both unnecessary morbidity and has been linked to mortality in the past.

Self-management education and regular practitioner review for adults with asthma

BACKGROUND

A key component of many asthma management guidelines is the recommendation for patient education and regular medical review. A number of controlled trials have been conducted to measure the effectiveness of asthma education programmes. These programmes improve patient knowledge, but their impact on health outcomes is less well established. This review was conducted to examine the strength of evidence supporting Step 6 of the Australian Asthma Management Plan: "Educate and Review Regularly"; to test whether health outcomes are influenced by education and self-management programmes.

OBJECTIVES

The objective of this review was to assess the effects of asthma self-management programmes, when coupled with regular health practitioner review, on health outcomes in adults with asthma.

SEARCH STRATEGY

We searched the Cochrane Airways Group trials register and reference lists of articles.

SELECTION CRITERIA

Randomised trials of self-management education in adults over 16 years of age with asthma.

DATA COLLECTION AND ANALYSIS

Trial quality was assessed and data were extracted independently by two reviewers. Study authors were contacted for confirmation.

MAIN RESULTS

Twenty-five trials were included. Self-management education was compared with usual care in 22 studies. Self-management education reduced hospitalisations (odds ratio 0.57, 95% confidence interval 0.38 to 0.88); emergency room visits (odds ratio 0.71, 95% confidence interval (0.57 to 0.90); unscheduled visits to the doctor (odds ratio 0.57, 95% confidence interval 0.40 to 0.82); days off work or school (odds ratio 0.55, 95% confidence interval 0.38 to 0. 79); and nocturnal asthma (odds ratio 0.53, 95% confidence interval 0.39 to 0.72). Measures of lung function were little changed. Self-management programmes that involved a written action plan showed a greater reduction in hospitalisation than those that did not (odds ratio 0.35, 95% confidence interval 0.18 to 0.68). People who managed their asthma by self-adjustment of their medications using an individualised written plan had better lung function than those whose medications were adjusted by a doctor.

REVIEWER'S CONCLUSIONS

Training in asthma self-management which involves self-monitoring by either peak expiratory flow or symptoms, coupled with regular medical review and a written action plan appears to improve health outcomes for adults with asthma. Training programmes which enable people to adjust their medication using a written action plan appear to be more effective than other forms of asthma self-management.

Limited (information only) patient education programs for adults with asthma

BACKGROUND

A key component of many asthma management guidelines is the recommendation for patient education and regular medical review. A number of controlled trials have been conducted to measure the effectiveness of asthma education programmes. These programmes improve patient knowledge, but their impact on health outcomes is less well established. At its simplest level, education is limited to the transfer of information about asthma, its causes and its treatment. This review focused on the effects of limited asthma education.

OBJECTIVES

The objective of this review was to assess the effects of limited (i.e. information only) asthma education on health outcomes in adults with asthma.

SEARCH STRATEGY

We searched the Cochrane Airways Group trials register and reference lists of articles.

SELECTION CRITERIA

Randomised and controlled trials of individual asthma education involving information transfer only in adults over 16 years of age.

DATA COLLECTION AND ANALYSIS

Trial quality was assessed and data were extracted independently by two reviewers. Study authors were contacted for missing information.

MAIN RESULTS

Eleven trials were included. They were of variable quality. Limited asthma education did not reduce hospitalisation for asthma (weighted mean difference -0.03 average hospitalisations per person per year, 95% confidence interval -0.09 to 0.03). There was no effect on doctor visits, lung function and medication use. The effects on asthma symptoms were variable. There was no reduction in days lost from normal activity, but perceived asthma symptoms did improve after limited asthma education (odds ratio 0.40, 95% confidence interval 0.18 to 0.86). In one study, limited asthma education was associated with reduced emergency department visits (weighted mean difference -2.76 average visits per person per year, 95% confidence interval -4.34 to 1.18).

REVIEWER'S CONCLUSIONS

Use of limited asthma education as it has been practiced does not appear to improve health outcomes in adults with asthma. However the use of information in the emergency department may be effective, but this needs to be confirmed.

Adults' experience with asthma and their reported uncertainty and coping strategies

This study examined the uncertainty experienced by persons with asthma and the coping strategies they used. The sample of 99 adults was interviewed by the investigators. Subjects responded to demographic and illness-related questions and completed the Mishel Uncertainty in Illness Scale and the Jalowiec Coping Scale. Subjects who had asthma for a longer duration reported lower levels of uncertainty. Those who were hospitalized because of asthma and those for whom pollen was a trigger experienced greater uncertainty. Females, individuals who went to an emergency department because of asthma, and those who attended pulmonary support groups used more coping strategies. Understanding the sources of perceived uncertainty may assist individuals to cope with and manage the chronic and acute phases of asthma.

Asthmatic patients' views of a comprehensive asthma rehabilitation programme: a three-year follow-up

BACKGROUND AND PURPOSE

Twenty-one asthmatic patients aged 27-59 years, with mild to moderate asthma, participated in a 10-week group rehabilitation programme covering physical training and theoretical and practical education in medication, self-management strategies and physiotherapy. This study was undertaken retrospectively to investigate (1) the patients' reasons for joining the programme, (2) their experiences of the programme, and (3) their ways of coping with disease-related problems before joining and three years after completion of the programme.

METHODS

Patients were followed up every six months for three years and were interviewed after the three years. The semi-structured interviews were tape-recorded, transcribed and revised.

RESULTS

The life-situation of most of the patients before the 10-week programme was characterized by helplessness at exacerbations, anxiety/insecurity about medications and their side-effects, and/or concern about future health. More than half of the subjects felt physical limitations in daily life or when exercising. All wished to increase their knowledge of asthma by joining the programme, but only nine patients expected asthma improvement. The experience that they were able to carry out physical exercise to a maximal intensity and that physical training improved their asthma, with increased knowledge about medications were mentioned by all as the most valuable effects of the programme. Moreover, most patients emphasized their increased ability in self-management strategies (stress reduction and breathing technique). The increased knowledge and improved practical skills contributed to a better life-situation after the rehabilitation. After the three years virtually all the patients' lives were characterized by improved self-management, increased physical activity and a sense of security. Almost half of them expressed a wish to take responsibility for the disease.

CONCLUSIONS

In addition to medical therapy and education, physical training and techniques for relaxation and breathing should form part of the treatment of asthma.

Planning an integrated population-based program

Social, economic, and political pressures demand that hospitals focus on ways to provide cost-effective, population-based care. As a member of the hospital executive staff, nurse administrators need to have a method for analyzing, planning, implementing, and evaluating prospective programs and be able to articulate their potential and relative worth in terms of cost, quality, and value. The author presents a template model for integrated population-based program planning. Children's Home-Based Asthma Management and Prevention Service (CHAMPS) is presented to illustrate application of the model.

Self-management of asthma by adult patients

Review of eighteen adult self-management education program evaluations comprising clinical trials showed significant achievement in five categories of outcome: (1) asthma knowledge; (2) patient perceptions and psychological status; (3) behavior related to medicine use, delivery devices and environmental triggers; (4) functioning and control of symptoms; and (5) health care use. Not every program achieved in all of these categories, probably because interventions of adequate power to elicit change in one category of outcome were not powerful enough to realize change in another category. An alternative explanation may be that in some studies assessment measures were inadequate. Asthma management by patients is influenced by their social environment and this aspect of control is least well understood. A small qualitative study suggested themes among adult patients that describe intra- and interpersonal factors enabling or hindering self-management including: the ability to acquire information; self-regulation; relations with family, friends and coworkers; and, relationships with clinicians. Research is needed that provides greater understanding of social environments in asthma management, produces standardized measurement tools, and tests more robust and theory-based interventions.

Individual versus group education: is one better?

Individual and small group approaches to delivering patient education have differing potential advantages, and various criteria can be used to determine which is "better". Individualization of education is possible in either delivery format, as is its absence. Limited evidence regarding the relative effectiveness and cost-effectiveness of different delivery modes is available from direct comparison and meta-analyses of studies comparing either of the approaches with no education or the patient's own pre-education status. This evidence supports the conclusions that: (1) both individual and group education can improve patient outcomes, (2) it is not possible to conclude that the two delivery formats are essentially equivalent in effectiveness, and there is some evidence that group education may more effective for some outcomes, and (3) wide variation in effectiveness exists among programs in both delivery formats. A model continuum of asthma education is presented that takes advantage of the respective strengths of individual and group delivery.

Educational needs of stroke survivors and their family members, as perceived by themselves and by health professionals

This study identified informational needs of stroke survivors and their family members as perceived by themselves and by health professionals. The source of information, and the desired source for future information were also explored. Green's Precede-Proceed model was used as a theoretical framework. In the study 35 stroke survivors, 39 family members and 43 health professionals participated. The results show that stroke survivors and family members indicated to desire the most information regarding reducing the chance of a new stroke. Stroke survivors rated as the major gaps of information: reducing the chance of a new stroke and coping with stress. Family members rated as the major gaps of information: sources to apply for help; strategies to perform activities of daily living, and reducing the chance of a new stroke. Stroke survivors and their family members expressed as the most desired source of information the doctor in the hospital. Health professionals expressed a high level of concern about the amount of information stroke survivors and family members receive; they expressed a substantial need for information about all topics for both groups, which should be provided by several sources. Some needs are recognized, but in most cases not met. Family members of stroke survivors who suffered more than one stroke seem to have received more information--and to desire less. Both highly educated stroke survivors and family members indicate to have received less information and desire more information than lower educated respondents.

Risk factors for recurrent emergency department visits for asthma

BACKGROUND

Patients presenting with asthma to emergency departments have lost control of their disease, have significant airways obstruction, and frequently require admission to hospital. Although even one visit is not desirable, there is a more disturbing subgroup who repeatedly visit the emergency department.

METHODS

To investigate the reasons for multiple emergency visits, a questionnaire was given to 448 consecutive patients presenting to the two largest adult emergency departments in Ottawa, Canada between November 1989 and April 1991. Within this cohort, those who had made at least three visits in the past year were compared with controls (only one visit in the past year).

RESULTS

Although inhaled corticosteroid use increased with multiple visits (indicating increased asthma severity), only 60% of those visiting at least three times in the past year were taking inhaled corticosteroids. Chronic undermedication relative to disease severity was apparent among the cases. The number of visits was associated with nocturnal asthma on a regular basis, work and school absenteeism, frequent visits to their regular physician, and frequent admissions to hospital. Visits were not related to psychological health, environmental allergens/irritants, or lack of perceived asthma severity.

CONCLUSIONS

The recommendations of current asthma guidelines are not reaching these patients. The issue of translating guidelines from paper to practice must be addressed before highly effective medications can have an important impact on the frequency of emergency department visits.

Patients' opinions on respiratory care: do doctors fulfill their needs?

To date, guidelines and consensus reports on quality care for asthma and chronic obstructive pulmonary disease (COPD) are mainly based on research and opinions of care providers. Patients' viewpoints on good medical care have rarely been studied. We designed a postal questionnaire to study the needs of patients with asthma or COPD for medical care provided by general practitioners and lung physicians. A total of 121 patients filled out the questionnaire, which included 111 items about needs. Although generally satisfied, patients reported several unfulfilled needs. Main topics were the need for information about diagnostic tests, prognosis, and long-term use of medication. In addition, patients wanted more written information about the nature of their disease. One-third of patients wanted more participation in decisions about their treatment. These results suggest the quality of medical care for patients with asthma or COPD can be improved by adjusting provided care to needs expressed by patients.

Managed care and the treatment of asthma

Few diagnoses offer managed care more return for the investment than asthma. Physicians are beset by mandates to use more anti-inflammatory therapy, peak flow meters, spacer devices, and written step care plans. The managed care system offers the organization and resources to meet this challenge to support physicians on the front line. Economies of scale and computer data bases now make asthma care outcome measures available for evaluation and revision. The current review focuses on five areas for development of successful asthma intervention: (1) physician education, (2) the comanagement concept, (3) patient education, (4) cost-effectiveness, and (5) implementation.

An educational needs assessment of children with juvenile rheumatoid arthritis

OBJECTIVE

Our objective is to describe the use of the PRECEDE model (predisposing, reinforcing, and enabling causes in educational diagnosis and evaluation) to organize needs assessment data in order to define self-management behaviors and plan an educational intervention for children with juvenile rheumatoid arthritis (JRA) and their families.

METHODS

Analysis was done of needs assessment data collected from several sources: 1) literature review, 2) survey of parents of 51 children with JRA, 3) group interview of seven parents of children with JRA, 4) results of pilot programs, and 5) clinical experience of an interdisciplinary pediatric rheumatology team.

RESULTS

Two sets of interrelated behavioral factors were identified through the needs assessment: 1) those related to managing the school environment to facilitate optimal participation and to minimize school-related disability, and 2) those related to treating pain and stiffness, intervening in the disease process, and preserving joint function.

CONCLUSION

Both of these sets of behavioral factors may be related to the optimization of children's mobility, joint function, and autonomy of activities of daily living and should be targets of an educational intervention.

Measuring adherence to asthma medication regimens

The failure of patients to adhere to physician-prescribed regimens, either pharmacologic or behavioral, has been well documented in medical literature. Poor adherence to asthma medication regimens has been repeatedly demonstrated in both children and adults, with rates of nonadherence commonly reported from 30 to 70%. Medication regimens for asthma care are particularly vulnerable to adherence problems because of their duration, the use of multiple medications, and the periods of symptom remission. The clinical effects of this nonadherence by asthmatic patients can include treatment failure, unnecessary and dangerous intensification of therapy, and costly diagnostic procedures, complications, and hospitalizations. Although the measurement of adherence is an important component of both medical and behavioral interventions to control asthma, relatively little research has directly addressed the reliability and validity of the measures most widely used to assess asthma medication compliance. This review will discuss methods and issues in the measurement of adherence in general, and where available, measures that have been specifically used in evaluating adherence to asthma medication. Common measures used to assess compliance with asthma medications include direct measures, which confirm the use of medication by assaying it in blood, urine, or saliva, or which confirm the to use a medication, such as observed skill in using a metered dose inhaler. Indirect measures infer use with varying degrees of reliability, by use of clinical judgment, self-report/asthma diaries, medication measurement, and electronic medication monitors. The uses and limitations of these measures will be discussed.

Scale for assessing functional impairment in adults with asthma

Improved outcome measures for asthma research, especially measures of functional status and quality of life, have become increasingly important. This research describes one such measure, the University of Alabama at Birmingham (UAB) Functional Impairment Scale. This scale consists of eight items to assess the impact of asthma on various aspects of daily living. The psychometric properties of the UAB Scale were assessed in two samples. The coefficient alpha reliabilities were high in both samples (.83 and .84), and the item-total correlations indicated all items were measuring the same trait. The score distributions covered the entire range of possible scores, and the central tendencies and dispersions confirmed the presence of enough variation to detect differences in functional impairment among individuals. Correlations between the UAB Scale and other asthma-related measures support construct validity. All of these results support the potential usefulness of the UAB Scale.

Patient and family management of asthma: theory-based techniques for the clinician

Several model asthma education programs are available to improve patient self-management, and elements of these models are discussed as they relate to the teaching role of health-care providers. Self-regulation is being explored in current asthma education research, and preliminary findings of a study are presented that show self-regulation behaviors to be associated with more frequent use of asthma management strategies by patients. Using more management strategies was associated with being observant of symptoms (p = .0001) and feeling confident to manage them (p = .01). Taking more preventive actions was associated with being observant (p = .001) and feeling confident to keep the child out of the triggering situation (p = .02) and prevent symptoms (p = .001). Important issues arising from recent psychosocial research are outlined for consideration by the clinician. These include ways that counseling by the health professional can encourage self-regulation and better at-home management of asthma.

Use of focus group methodology to develop an asthma self-management program useful for community-based medical practices

Health education programs developed in academic medical centers are not optimally disseminated to community clinical settings. Strategies are needed to translate the findings of research on health education programs into programs useful in a wide range of health care settings. Focus group techniques were used to provide data for revising a successful university-based asthma self-management program to make it more practical for use by community physicians. Physicians representing a variety of specialties attended the sessions and provided feedback on the utility of various components of the original program. The discussions revealed that many physicians felt they did not have the time or resources to conduct the original program and identified elements viewed as impractical. This physician input contributed significantly to the development of a revised program with a briefer, less costly intervention. The revised program was later evaluated by focus group participants. Eighty-eight percent of those who evaluated the revised program agreed they would be able and willing to use the program in their own practices. As a formative evaluation tool, the focus group technique made available useful information that would have been difficult to obtain through evaluation forms alone.

A controlled trial of two forms of self-management education for adults with asthma

PURPOSE

Excess morbidity and mortality due to asthma, aggravated by demonstrably poor patient self-management practices, suggest the need for formal patient education programs. Individual and group asthma education programs were developed and evaluated to determine their cognitive, behavioral, and clinical effects.

PATIENTS AND METHODS

We compared changes in asthma symptoms, utilization of medical services, knowledge about asthma, metered-dose inhaler (MDI) technique, and self-management behaviors for 323 adult Kaiser Permanente patients with moderate to severe asthma who were randomly assigned to small-group education, individual teaching, or 1 of 2 control conditions--an information (workbook) control or usual control (no formal asthma education). Data were collected from patients by questionnaire, diary, and physical examination at enrollment and at 5 months and 1 year after intervention. Medical record data on these patients were abstracted for a total 3-year period, from 1 year before to 2 years after enrollment.

RESULTS

Compared with the usual control, the self-management education programs were associated with significant improvements in control of asthma symptoms (reduced "bother" due to asthma and increased symptom-free days), MDI technique, and environmental control practices. Small-group education also was associated with significant improvements in physician evaluation of the patients' asthma status and in patients' level of physical activity. For both group and individual education recipients, improvement in MDI technique was positively correlated with improved control of symptoms; however, the degree of improvement in symptoms was greater than that which could be accounted for on the basis of improvement in MDI technique alone. The time course over which changes occurred in the various outcome measures suggests the mechanism by which education resulted in improvement in the patient's status. Significant improvements in MDI technique and environmental control practices were manifest immediately following education (5-month follow-up) and at the 1-year follow-up. Significant improvements in symptom measures were not apparent until the 1-year follow-up. The rate of utilization of medical care for acute exacerbations decreased between baseline and the 2-year follow-up period, but this decrease did not differ significantly among treatment conditions. However, there was a trend toward greater reduction in patients receiving small-group education. An ad hoc finding of a significant difference favoring small-group education between the baseline and the second follow-up year acute visit rates was observed. This result must be regarded as tentative, since it is not clear that unambiguous statistical significance is attained in the light of multiplicity issues. However, this trend is consistent with the antecedent benefits of the small-group education, and appears to warrant further investigation.

CONCLUSIONS

Carefully designed asthma education programs for adults can improve patients' understanding of their condition and its treatment and increase their motivation and confidence that the condition can be controlled, thereby increasing their adherence to the treatment regimen and management of symptoms, and, in turn, improving control of symptoms. Both small-group education and individual education were associated with significant benefits, but the group program was simpler to administer, better received by patients and educators, and more cost-effective. The results show promise for improving clinical outcomes, through well-designed educational programs, for patients with asthma and other chronic health problems.

Asthma severity: a factor analytic investigation

PURPOSE

Reviewers of the asthma research literature have called for improved questionnaires and other measures, particularly for assessing the severity of asthma. To help meet this need, standard multivariate and psychometric techniques were used with data from asthma patients to develop and evaluate a series of scaled questions. Since there is no "gold standard" for assessing asthma severity, we hope this analysis will help improve our ability to more precisely define these important parameters.

PATIENTS AND METHODS

Data were collected through interviews and review of clinic records for 199 adult patients with asthma from a university clinic population. For evaluating the severity of asthma, eight scales assessed asthma duration, the incidence of asthma symptoms, the extent to which asthma is an inconvenience to patients, the incidence of respiratory diseases, medication regimens, medication side effects, and health care utilization. Forced expiratory volume in 1 second as a percentage of predicted normal was included as an objective measure of pulmonary function. A physician rating scale assessed the severity of the underlying disease, not the severity of a particular episode, as either (1) mild (infrequent attacks with interim symptomatic treatment), (2) moderate (more frequent attacks with continuous daily treatment), and (3) severe (continuous symptom with continuous multiple drug regimen, including some systemic steroids).

RESULTS

In the current analysis of data from adult asthma patients, the scales correlated positively with a physician judgment scale. Factor analysis with an oblique rotation yielded three factors that provided a concise summary of asthma severity. We have named the factors (A) Symptom Intensity, (B) Airflow Impairment, and (C) Management Intensity.

CONCLUSION

Asthma severity appears to be multidimensional rather than unidimensional, including at least three components. The physician rating scale, in combination with measures of the three identified factors, could easily be included in other asthma research protocols to provide a standard, brief assessment of asthma severity and might thus promote greater comparability among studies.

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).

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.

Peak flow meters: are they monitoring tools or training devices?

Previous studies have been inconclusive as to whether peak flow meter use teaches asthma patients to better perceive their own pulmonary functioning. This investigation utilized a delayed baseline design to determine if pulmonary awareness could be improved among a sample of 24 adult patients who compared daily peak expiratory flow rates (PEFR) with asthma symptom ratings. Results indicated that among this sample of adult patients: (i) perception of pulmonary functioning was poor, (ii) adherence to peak flow meter use was poor, and (iii) among patients who use peak flow meters daily, self-perception of pulmonary functioning did not improve significantly. Summary tables and descriptive statistics for pulmonary functioning are provided, and treatment implications are discussed.

The Kidney Disease Questionnaire: a test for measuring patient knowledge about end-stage renal disease

Two studies report on the development of the Kidney Disease Questionnaire (KDQ) as a test for measuring patient knowledge about end-stage renal disease and its treatment. The KDQ is available in a 26-item version or as two parallel 13-item tests. Psychometric evaluations indicate that all versions show high levels of reliability. Initial validity tests are also promising. The KDQ is able to discriminate individuals well informed about kidney disease and its treatment from those who are not so well informed. It is also sensitive to the effects of an experimental education program and to ESRD-related knowledge that is acquired as a result of starting dialysis. Data and issues related to the administration, readability, demographic correlates, and a French translation of the KDQ are also presented and discussed.

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.

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.
