Evaluation of the efficacy of a hospital-based asthma education programme in patients of low socioeconomic status in Hong Kong

Video-Based Educational Interventions for Patients With Chronic Illnesses: Systematic Review

BACKGROUND

With rising time constraints, health care professionals increasingly depend on technology to provide health advice and teach patients how to manage chronic disease. The effectiveness of video-based tools in improving knowledge, health behaviors, disease severity, and health care use for patients with major chronic illnesses is not well understood.

OBJECTIVE

The aim of this study was to assess the current literature regarding the efficacy of video-based educational tools for patients in improving process and outcome measures across several chronic illnesses.

METHODS

A systematic review was conducted using CINAHL and PubMed with predefined search terms. The search included studies published through October 2021. The eligible studies were intervention studies of video-based self-management patient education for an adult patient population with the following chronic health conditions: asthma, chronic kidney disease, chronic obstructive pulmonary disease, chronic pain syndromes, diabetes, heart failure, HIV infection, hypertension, inflammatory bowel disease, and rheumatologic disorders. The eligible papers underwent full extraction of study characteristics, study design, sample demographics, and results. Bias was assessed with the Cochrane risk-of-bias tools. Summary statistics were synthesized in Stata SE (StataCorp LLC). Data reporting was conducted per the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) checklist.

RESULTS

Of the 112 studies fully extracted, 59 (52.7%) were deemed eligible for inclusion in this review. The majority of the included papers were superiority randomized controlled trials (RCTs; 39/59, 66%), with fewer pre-post studies (13/59, 22%) and noninferiority RCTs (7/59, 12%). The most represented conditions of interest were obstructive lung disease (18/59, 31%), diabetes (11/59, 19%), and heart failure (9/59, 15%). The plurality (28/59, 47%) of video-based interventions only occurred once and occurred alongside adjunct interventions that included printed materials, in-person counseling, and interactive modules. The most frequently studied outcomes were disease severity, health behavior, and patient knowledge. Video-based tools were the most effective in improving patient knowledge (30/40, 75%). Approximately half reported health behavior (21/38, 56%) and patient self-efficacy (12/23, 52%) outcomes were improved by video-based tools, and a minority of health care use (11/28, 39%) and disease severity (23/69, 33%) outcomes were improved by video-based tools. In total, 48% (22/46) of the superiority and noninferiority RCTs and 54% (7/13) of the pre-post trials had moderate or high risk of bias.

CONCLUSIONS

There is robust evidence that video-based tools can improve patient knowledge across several chronic illnesses. These tools less consistently improve disease severity and health care use outcomes. Additional study is needed to identify features that maximize the efficacy of video-based interventions for patients across the spectrum of digital competencies to ensure optimized and equitable patient education and outcomes.

Asthma education and its impact on pediatric asthma severity: a prospective cohort study

OBJECTIVE

Asthma education has been shown to improve asthma control. Our goal was to evaluate the efficacy of asthma education on the frequency of utilization of health-care services, lung function results, degree of asthma severity, and quality of life (QOL) level in children with asthma.

METHODS

A single-arm prospective interventional trial was conducted in a tertiary facility. Thirty children with asthma and their parents were recruited for the research. Following an assessment of the participants' and caregivers' knowledge about asthma using an asthma knowledge questionnaire, degree of asthma control using asthma control test, inhaler technique using standardized inhaler technique checklists, and QOL using pediatric asthma QOL questionnaires, they participated in a three-month education program in the form of monthly live interactive sessions followed by weekly phone interviews. Measures taken before and after the intervention were compared.

RESULTS

The educational intervention improved asthma control dramatically including daytime asthma symptoms, night awakenings, and frequency of use of short-acting beta2- adrenergic receptor agonists. Furthermore, the number of emergency department visits and hospitalizations fell considerably after the intervention (p < 0.001 for all). Asthma education was also linked to better inhalation technique and lung function (p < 0.001). Furthermore, all quality-of-life measures increased (p < 0.001 for all).

CONCLUSIONS

Implementing an asthma education program that included both children with asthma and their parents improved asthma control levels, lung function measures, and overall quality of life. Furthermore, it increased asthma awareness, decreased the use of health-care resources, and reduced asthma severity, resulting in better asthma management.

Impact of Group Asthma Education on Asthma Control and Emergency Room Visits in an Underserved New York Community

Objective

Asthma education programs have been shown to be effective in decreasing health care utilization and improving disease control and management. However, there are few studies evaluating the outcomes of group asthma education. The aim of this study was to assess the impact of an outpatient adult group asthma education program in an inner-city-based hospital caring for an underserved population.

Methods

We conducted a pre- and poststudy of all patients with asthma who participated in two structured group asthma education sessions led by a respiratory therapist, clinical pharmacist, and pulmonologist. The study period (January 2016 to April 2018) included the year before group education and the year after education. The primary outcomes were the number of patients requiring emergency room visits and hospital admission. The secondary outcomes included asthma control as assessed by Asthma Control Test scores, use of systemic corticosteroids, and change in test scores postintervention.

Results

Eighty-eight patients received group education during the study period; 82 attended 2/2 sessions, and 6 attended 1/2 sessions. The study population was largely Hispanic (73%) or African American (25%) and had a mean age of 58 years. Most had moderate (57%) or severe (25%) persistent asthma. Significantly, fewer patients required emergency room visits in the postintervention period than in the preintervention period (20 visits vs. 42 visits, p=0.0002). Group education was also associated with increased asthma control (p=0.0043), decreased use of systemic corticosteroids (p=0.0005), and higher postintervention test scores (p=0.0001).

Conclusions

Group asthma education provided by a multidisciplinary team in an inner-city hospital clinic caring for underserved and minority populations is feasible and may decrease utilization of health care resources when patients are educated and empowered to participate in their asthma management.

Caseworker-assigned discharge plans to prevent hospital readmission for acute exacerbations in children with chronic respiratory illness

BACKGROUND

Chronic respiratory conditions are major causes of mortality and morbidity. Children with chronic health conditions have increased morbidity associated with their physical, emotional, and general well-being. Acute respiratory exacerbations (AREs) are common in children with chronic respiratory disease, often requiring admission to hospital. Reducing the frequency of AREs and recurrent hospitalisations is therefore an important goal in the individual and public health management of chronic respiratory illnesses in children. Discharge planning is used to decide what a person needs for transition from one level of care to another and is usually considered in the context of discharge from hospital to the home. Discharge planning from hospital for ongoing management of an illness has historically been referral to a general practitioner or allied health professional or self management by the individual and their family with limited communication between the hospital and patient once discharged. Effective discharge planning can decrease the risk of recurrent AREs requiring medical care. An individual caseworker-assigned discharge plan may further decrease exacerbations.

OBJECTIVES

To evaluate the efficacy of individual caseworker-assigned discharge plans, as compared to non-caseworker-assigned plans, in preventing hospitalisation for AREs in children with chronic lung diseases such as asthma and bronchiectasis.

SEARCH METHODS

We searched the Cochrane Airways Group Specialised Register of Trials, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, trials registries, and reference lists of articles. The latest searches were undertaken in November 2017.

SELECTION CRITERIA

All randomised controlled trials comparing individual caseworker-assigned discharge planning compared to traditional discharge-planning approaches (including self management), and their effectiveness in reducing the subsequent need for emergency care for AREs (hospital admissions, emergency department visits, and/or unscheduled general practitioner visits) in children hospitalised with an acute exacerbation of chronic respiratory disease. We excluded studies that included children with cystic fibrosis.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane Review methodological approaches. Relevant studies were independently selected in duplicate. Two review authors independently assessed trial quality and extracted data. We contacted the authors of one study for further information.

MAIN RESULTS

We included four studies involving a total of 773 randomised participants aged between 14 months and 16 years. All four studies involved children with asthma, with the case-planning undertaken by a trained nurse educator. However, the discharge planning/education differed among the studies. We could include data from only two studies (361 children) in the meta-analysis. Two further studies enrolled children in both inpatient and outpatient settings, and one of these studies also included children with acute wheezing illness (no previous asthma diagnosis); the data specific to this review could not be obtained. For the primary outcome of exacerbations requiring hospitalisation, those in the intervention group were significantly less likely to be rehospitalised (odds ratio (OR) 0.29, 95% confidence interval (CI) 0.16 to 0.50) compared to controls. This equates to 189 (95% CI 124 to 236) fewer admissions per 1000 children. No adverse events were reported in any study. In the context of substantial statistical heterogeneity between the two studies, there were no statistically significant effects on emergency department (OR 0.37, 95% CI 0.04 to 3.05) or general practitioner (OR 0.87, 95% CI 0.22 to 3.44) presentations. There were no data on cost-effectiveness, length of stay of subsequent hospitalisations, or adherence to medications. One study reported quality of life, with no significant differences observed between the intervention and control groups.We considered three of the studies to have an unclear risk of bias, primarily due to inadequate description of the blinding of participants and investigators. The fourth study was assessed as at high risk of bias as a single unblinded investigator was used. Using the GRADE system, we assessed the quality of the evidence as moderate for the outcome of hospitalisation and low for the outcomes of emergency department visits and general practitioner consultations.

AUTHORS' CONCLUSIONS

Current evidence suggests that individual caseworker-assigned discharge plans, as compared to non-caseworker-assigned plans, may be beneficial in preventing hospital readmissions for acute exacerbations in children with asthma. There was no clear indication that the intervention reduces emergency department and general practitioner attendances for asthma, and there is an absence of data for children with other chronic respiratory conditions. Given the potential benefit and cost savings to the healthcare sector and families if hospitalisations and outpatient attendances can be reduced, there is a need for further randomised controlled trials encompassing different chronic respiratory illnesses, ethnicity, socio-economic settings, and cost-effectiveness, as well as defining the essential components of a complex intervention.

Video-based patient decision aids: A scoping review

OBJECTIVE

This study reviews the published literature on the use of video-based decision aids (DA) for patients. The authors describe the areas of medicine in which video-based patient DA have been evaluated, the medical decisions targeted, their reported impact, in which countries studies are being conducted, and publication trends.

METHOD

The literature review was conducted systematically using Medline, Embase, CINAHL, PsychInfo, and Pubmed databases from inception to 2016. References of identified studies were reviewed, and hand-searches of relevant journals were conducted.

RESULTS

488 studies were included and organized based on predefined study characteristics. The most common decisions addressed were cancer screening, risk reduction, advance care planning, and adherence to provider recommendations. Most studies had sample sizes of fewer than 300, and most were performed in the United States. Outcomes were generally reported as positive. This field of study was relatively unknown before 1990s but the number of studies published annually continues to increase.

CONCLUSION

Videos are largely positive interventions but there are significant remaining knowledge gaps including generalizability across populations.

PRACTICE IMPLICATIONS

Clinicians should consider incorporating video-based DA in their patient interactions. Future research should focus on less studied areas and the mechanisms underlying effective patient decision aids.

Knowledge and Beliefs of Parents of Asthmatic Children Presenting to an Emergency Department

This is a survey on the knowledge and beliefs of 100 parents or guardians of asthmatic children presenting to the emergency department with an asthmatic attack and staying in the observation ward for treatment. The parents were asked to fill in a questionnaire on their knowledge and beliefs about asthma. Demographic data and data related to routine asthma care were also collected. The mean age of the children was 6.2± 3.2. The mean duration of asthma was 3.4 year (±2.6). In the preceding 6 months the mean attendance frequency at our accident and Energency department was 1.5±1.4. The majority of respondent (79%) agreed that asthma is caused by bronchoconstriction but only 42% understood that mucosal oedema is involved during an acute attack. Many people (82%) believed that asthma is just sensitive bronchus. Less than half (40%) believes asthma is a hereditary disease. It was a common belief that asthmatic attack can be precipitated by a change of weather (89%) and cold food/drink (77%). Over 75% agreed that carpet in the house is undesirable for an asthmatic child. The majority of parents (69%) disagreed that an asthmatic child should avoid physical exercise and only 13 would not allow the child to attend physical exercise class. Over half (54%) of the respondents believed that asthma could be cured. Only a minority (17%) believed that antibiotics are useful in shortening the attack. Thirty (30%) respondents also used alternative means of therapy for example crocodile meat. Parents' knowledge of preventive medication was inadequate. Understanding common beliefs among parents is beneficial in patient and parental education.

Culture-specific programs for children and adults from minority groups who have asthma

BACKGROUND

People with asthma who come from minority groups often have poorer asthma outcomes, including more acute asthma-related doctor visits for flare-ups. Various programmes used to educate and empower people with asthma have previously been shown to improve certain asthma outcomes (e.g. adherence outcomes, asthma knowledge scores in children and parents, and cost-effectiveness). Models of care for chronic diseases in minority groups usually include a focus of the cultural context of the individual, and not just the symptoms of the disease. Therefore, questions about whether tailoring asthma education programmes that are culturally specific for people from minority groups are effective at improving asthma-related outcomes, that are feasible and cost-effective need to be answered.

OBJECTIVES

To determine whether culture-specific asthma education programmes, in comparison to generic asthma education programmes or usual care, improve asthma-related outcomes in children and adults with asthma who belong to minority groups.

SEARCH METHODS

We searched the Cochrane Register of Controlled Trials (CENTRAL), the Cochrane Airways Group Specialised Register, MEDLINE, Embase, review articles and reference lists of relevant articles. The latest search fully incorporated into the review was performed in June 2016.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing the use of culture-specific asthma education programmes with generic asthma education programmes, or usual care, in adults or children from minority groups with asthma.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected, extracted and assessed the data for inclusion. We contacted study authors for further information if required.

MAIN RESULTS

In this review update, an additional three studies and 220 participants were added. A total of seven RCTs (two in adults, four in children, one in both children and adults) with 837 participants (aged from one to 63 years) with asthma from ethnic minority groups were eligible for inclusion in this review. The methodological quality of studies ranged from very low to low. For our primary outcome (asthma exacerbations during follow-up), the quality of evidence was low for all outcomes. In adults, use of a culture-specific programme, compared to generic programmes or usual care did not significantly reduce the number of participants from two studies with 294 participants for: exacerbations with one or more exacerbations during follow-up (odds ratio (OR) 0.80, 95% confidence interval (CI) 0.50 to 1.26), hospitalisations over 12 months (OR 0.83, 95% CI 0.31 to 2.22) and exacerbations requiring oral corticosteroids (OR 0.97, 95% CI 0.55 to 1.73). However, use of a culture-specific programme, improved asthma quality of life scores in 280 adults from two studies (mean difference (MD) 0.26, 95% CI 0.17 to 0.36) (although the MD was less then the minimal important difference for the score). In children, use of a culture-specific programme was superior to generic programmes or usual care in reducing severe asthma exacerbations requiring hospitalisation in two studies with 305 children (rate ratio 0.48, 95% CI 0.24 to 0.95), asthma control in one study with 62 children and QoL in three studies with 213 children, but not for the number of exacerbations during follow-up (OR 1.55, 95% CI 0.66 to 3.66) or the number of exacerbations (MD 0.18, 95% CI -0.25 to 0.62) among 100 children from two studies.

AUTHORS' CONCLUSIONS

The available evidence showed that culture-specific education programmes for adults and children from minority groups are likely effective in improving asthma-related outcomes. This review was limited by few studies and evidence of very low to low quality. Not all asthma-related outcomes improved with culture-specific programs for both adults and children. Nevertheless, while modified culture-specific education programs are usually more time intensive, the findings of this review suggest using culture-specific asthma education programmes for children and adults from minority groups. However, more robust RCTs are needed to further strengthen the quality of evidence and determine the cost-effectiveness of culture-specific programs.

Chronic disease management programmes for adults with asthma

BACKGROUND

The burden of asthma on patients and healthcare systems is substantial. Interventions have been developed to overcome difficulties in asthma management. These include chronic disease management programmes, which are more than simple patient education, encompassing a set of coherent interventions that centre on the patients' needs, encouraging the co-ordination and integration of health services provided by a variety of healthcare professionals, and emphasising patient self-management as well as patient education.

OBJECTIVES

To evaluate the effectiveness of chronic disease management programmes for adults with asthma.

SEARCH METHODS

Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Effective Practice and Organisation of Care (EPOC) Group Specialised Register, MEDLINE (MEDLINE In-Process and Other Non-Indexed Citations), EMBASE, CINAHL, and PsycINFO were searched up to June 2014. We also handsearched selected journals from 2000 to 2012 and scanned reference lists of relevant reviews.

SELECTION CRITERIA

We included individual or cluster-randomised controlled trials, non-randomised controlled trials, and controlled before-after studies comparing chronic disease management programmes with usual care in adults over 16 years of age with a diagnosis of asthma. The chronic disease management programmes had to satisfy at least the following five criteria: an organisational component targeting patients; an organisational component targeting healthcare professionals or the healthcare system, or both; patient education or self-management support, or both; active involvement of two or more healthcare professionals in patient care; a minimum duration of three months.

DATA COLLECTION AND ANALYSIS

After an initial screen of the titles, two review authors working independently assessed the studies for eligibility and study quality; they also extracted the data. We contacted authors to obtain missing information and additional data, where necessary. We pooled results using the random-effects model and reported the pooled mean or standardised mean differences (SMDs).

MAIN RESULTS

A total of 20 studies including 81,746 patients (median 129.5) were included in this review, with a follow-up ranging from 3 to more than 12 months. Patients' mean age was 42.5 years, 60% were female, and their asthma was mostly rated as moderate to severe. Overall the studies were of moderate to low methodological quality, because of limitations in their design and the wide confidence intervals for certain results.Compared with usual care, chronic disease management programmes resulted in improvements in asthma-specific quality of life (SMD 0.22, 95% confidence interval (CI) 0.08 to 0.37), asthma severity scores (SMD 0.18, 95% CI 0.05 to 0.30), and lung function tests (SMD 0.19, 95% CI 0.09 to 0.30). The data for improvement in self-efficacy scores were inconclusive (SMD 0.51, 95% CI -0.08 to 1.11). Results on hospitalisations and emergency department or unscheduled visits could not be combined in a meta-analysis because the data were too heterogeneous; results from the individual studies were inconclusive overall. Only a few studies reported results on asthma exacerbations, days off work or school, use of an action plan, and patient satisfaction. Meta-analyses could not be performed for these outcomes.

AUTHORS' CONCLUSIONS

There is moderate to low quality evidence that chronic disease management programmes for adults with asthma can improve asthma-specific quality of life, asthma severity, and lung function tests. Overall, these results provide encouraging evidence of the potential effectiveness of these programmes in adults with asthma when compared with usual care. However, the optimal composition of asthma chronic disease management programmes and their added value, compared with education or self-management alone that is usually offered to patients with asthma, need further investigation.

Sources of information and factual knowledge in Europeans with inflammatory bowel diseases: a cross-cultural comparison between German and Irish patients

BACKGROUND

Disease related knowledge may be associated with quality of life, coping skills and medication adherence. However, little is known of cross-cultural variations regarding inflammatory bowel disease knowledge or sources of information and no study has assessed knowledge in diverse European IBD populations.

AIM

To assess sources of information and patient knowledge in Irish and German inflammatory bowel disease patients.

METHODS

Three hundred and three disease, gender, age and education matched German and Irish patients completed a previously validated knowledge questionnaire. Additional data were collected on age, gender, education, disease type and duration, family history, smoking habits, medication use, previous surgery and quality of life.

RESULTS

German patients obtained knowledge from a wider range of sources than Irish patients (p<0.001), most notably from the internet (p<0.001), newspapers and magazines (p=0.002). Both cohorts answered a similar number of questions correctly (Irish, mean 4.4 questions (Standard deviation (S.D.) 2.4); German, mean 4.3 (S.D. 2.2); p=0.67). In addition, both nationalities answered "don't know" to a similar number of questions (Irish, mean 3.3 (S.D. 3.1); German, mean 2.7 (S.D. 2.8); p=0.12) while Irish patients answered slightly fewer questions wrongly (Irish, mean 2.4 (S.D. 1.8); German, mean 3.1 (S.D. 1.9); p=0.002). A multivariate analysis included only Crohn's disease, female gender, young age and higher educational status as being significantly and independently associated with knowledge.

CONCLUSIONS

Our data suggest few differences between German and Irish IBD patients, despite cultural and linguistic differences, with regard to disease related knowledge of IBD.

The self-care for people initiative: the outcome evaluation

AIM

To determine the effects of a community-based training programme in self-care on the lay population.

BACKGROUND

Self Care is recognised as being a cornerstone of the populations health, but to date there have been few large-scale studies of its effectiveness on the general public. This paper reports on an evaluation of a self-care skills training course delivered in small group sessions within workplace and parent and toddler group settings to a lay population.

METHODS

A quasi-experimental longitudinal study of 12-month duration was conducted in three intervention primary care trusts (PCTs) and two similar comparison PCTs in England. The sample comprised 1568 self-selecting participants: 868 received the intervention and 700 did not.

FINDINGS

No changes were seen in usage of General Practitioner services, the primary outcome, however, statistical analysis suggested that being in the intervention group may be associated with increased use of out-of-hours and secondary care services. At six months' follow-up small but statistically significant positive effects of being in the intervention group were seen on self-esteem, well-being and anxiety scores. At 12 months' follow-up small but statistically significant positive effects of being in the intervention group were also seen on recovery locus of control, health literacy and self-esteem scores, and on knowledge of adult cough. The clinical significance of these very small changes is unclear. The training programme had a small but positive effect, which was still evident at 12 months, on individuals' knowledge and confidence levels with regard to managing their own health, but did not lead to reductions in health service use.

Evaluation of chronic disease self-management programme (CDSMP) for older adults in Hong Kong

OBJECTIVES

To evaluate the locally-adapted CDSMP for older adults with chronic diseases in Hong Kong in the primary care setting.

DESIGN

A longitudinal, quasi-experimental study.

SETTING

Community-based and primary care setting.

PARTICIPANTS

Seven hundred and seventy-two participants aged 55 or above with at least one chronic disease and were living in the community.

INTERVENTION

The 6-weeks programme consisted of 6 group sessions, with each session lasting for 2.5 hours. Trained professional and elder lay leaders facilitated participants to gain essential self-management knowledge and skills for the effective management of chronic diseases.

MEASUREMENTS

At baseline and 6 months, four categories of outcome measures were documented, covering self-management behaviours, self-efficacy, health status, and health care utilization.

RESULTS

302 and 298 participants in the intervention and control groups completed 6 months follow-up respectively. Participants in the intervention group reported significant improvements in all self-management behaviours and self-efficacy measures, and 5 health status measures (social role limitation, depressive symptoms, health distress, symptoms of pain and discomfort, and self-rated health) when compared with those in the control group.

CONCLUSIONS

The locally-adapted CDSMP may improve self-management behaviours, self-efficacy and health status among older adults with chronic diseases in Hong Kong. CDSMP may be integrated into primary care services for older adults.

Educational and behavioral interventions for asthma: who achieves which outcomes? A systematic review

OBJECTIVES

Randomized clinical trial (RCT) data reviewed for outcomes and processes associated with asthma educational and behavioral interventions provided by different types of health professionals.

METHODS

Cochrane Collaboration, MEDLINE, PUBMED, Google Scholar search from 1998 to 2009 identified 1650 articles regarding asthma educational and behavioral interventions resulting in 249 potential studies and following assessment produced a final sample of 50 RCTs.

RESULTS

Approaches, intended outcomes, and program providers vary greatly. No rationale provided in study reports for the selection of specific outcomes, program providers, or program components. Health care utilization and symptom control have been the most common outcomes assessed. Specific providers favor particular teaching approaches. Multidisciplinary teams have been the most frequent providers of asthma interventions. Physician-led interventions were most successful for outcomes related to the use of health care. Multidisciplinary teams were best in achieving symptom reduction and quality of life. Lay persons were best in achieving self-management/self-efficacy outcomes. Components most frequently employed in successful programs are skills to improve patient-clinician communication and education to enhance patient self-management. Fifty percent of interventions achieved reduction in the use of health care and one-third in symptom control. A combination approach including self-management and patient-clinician communication involving multidisciplinary team members may have the greatest effect on most outcomes.

CONCLUSIONS

The extent to which and how different providers achieve asthma outcomes through educational and behavioral interventions is emerging from recent studies. Health care use and symptom control are evolving as the gold standard for intervention outcomes. Development of self-management and clinician-patient communication skills are program components associated with success across outcomes and providers.

Extended-stay hospitalization for childhood asthma in Japan

BACKGROUND

While recent advances in asthma management have enabled adequate control to be frequently achieved in outpatient settings, children whose asthma remains poorly controlled despite outpatient treatment are often referred to extended-stay hospitals. The aim of the present study was to examine trends concerning extended-stay hospitalization and to evaluate the present status of this approach.

METHODS

A retrospective study was conducted to assess changes in the number of admissions among 408 children with extended stays at Kamiamakusa General Hospital between 1989 and 2005. Medical and laboratory data of 236 patients admitted since 1994 were obtained from clinical records.

RESULTS

The number of children with extended-stay hospitalizations since 2000 declined dramatically compared with the early 1990s, while the percentage of patients with complications of childhood asthma, such as severe atopic dermatitis, school absenteeism, and obesity, have increased significantly in the recent past. Practical benefits of extended-stay hospitalization were demonstrated by significant improvement of exercise performance and measurement of pulmonary function parameters and serum IgE concentrations by time of discharge. In addition to improvement in asthmatic symptoms, maintenance drug requirements and frequency of school absenteeism were reduced.

CONCLUSIONS

The medical mission of extended-stay hospitalizations is currently limited due to the availability of improved pharmacotherapy. Some patients, however, with exceptionally severe asthma or psychological problems that interact with their medical condition still fare poorly under outpatient care and could benefit from group care. Further study is needed to identify the components of long-term programs essential to produce change.

Culture-specific programs for children and adults from minority groups who have asthma

BACKGROUND

People with asthma who come from minority groups have poorer asthma outcomes and more asthma related visits to Emergency Departments (ED). Various programmes are used to educate and empower people with asthma and these have previously been shown to improve certain asthma outcomes. Models of care for chronic diseases in minority groups usually include a focus of the cultural context of the individual and not just the symptoms of the disease. Therefore, questions about whether culturally specific asthma education programmes for people from minority groups are effective at improving asthma outcomes, are feasible and are cost-effective need to be answered.

OBJECTIVES

To determine whether culture-specific asthma programmes, in comparison to generic asthma education programmes or usual care, improve asthma related outcomes in children and adults with asthma who belong to minority groups.

SEARCH STRATEGY

We searched the Cochrane Register of Controlled Trials (CENTRAL), the Cochrane Airways Group Specialised Register, MEDLINE, EMBASE, review articles and reference lists of relevant articles. The latest search was performed in May 2008.

SELECTION CRITERIA

All randomised controlled trials (RCTs) comparing the use of culture-specific asthma education programmes with generic asthma education programmes, or usual care, in adults or children from minority groups who suffer from asthma.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected, extracted and assessed the data for inclusion. We contacted authors for further information if required.

MAIN RESULTS

Four studies were eligible for inclusion in the review. A total of 617 patients, aged from 5 to 59 years were included in the meta-analysis of data. Use of a culture-specific programme was superior to generic programmes or usual care, in improving asthma quality of life scores in adults, pooled WMD 0.25 (95% CI 0.09 to 0.41), asthma knowledge scores in children, WMD 3.30 (95% CI 1.07 to 5.53), and in a single study, reducing asthma exacerbation in children (risk ratio for hospitalisations 0.32, 95%CI 0.15, 0.70).

AUTHORS' CONCLUSIONS

Current limited data show that culture-specific programmes for adults and children from minority groups with asthma, are more effective than generic programmes in improving most (quality of life, asthma knowledge, asthma exacerbations, asthma control) but not all asthma outcomes. This evidence is limited by the small number of included studies and the lack of reported outcomes. Further trials are required to answer this question conclusively.

How well were asthmatic patients educated about their asthma? A study at the emergency department

70 patients presented with acute asthma exacerbation requiring nebulised bronchodilator treatment at the emergency department of a teaching hospital in Kuala Lumpur, Malaysia, were interviewed over a two-week period in July 2001. The results showed that 45 (64%) patients had not been educated on the nature of asthma; 30 (43%) had not been advised on preventive measures or avoidance of triggers; 54 (77%) were not advised about the medications used and their side effects; 42 (60%) patients did not know the difference between reliever and preventive medications; 37 (53%) were unable to recognize features of worsening asthma and 68 (97%) were not told about the danger of non-prescribed self-medication or traditional medications. Only six (9%) patients were using peak flow meters and were taught self-management plans. The multiple regression results suggest that patients who were followed up at teaching hospital based clinics were better educated on asthma. In conclusion, asthmatic patients are still not educated well about their disease. Health care providers need to put more emphasis on asthma education so that the number of emergency room visits can be reduced.

[Economic aspects of severe asthma]

Severe asthma and difficult-to-treat asthma are major issues in public health, given the mortality and morbidity they induce and their detrimental effects on patients' quality of life. The economic consequences should not be overlooked either. Published studies suggest that asthma-related medical resource use increases with the degree of asthma severity. Medical resource use incurred by severe (and/or difficult-to-treat) asthma could be reduced in part by more appropriate treatment, better patient education, improved coordination of disease management and treatment of comorbid diagnoses. The specific difficulties in the management of severe asthma and/or difficult-to-treat asthma must nonetheless be kept in mind. Recent new treatments appear promising, but their costs and indications in actual medical practice require better definition.

Education interventions for adults who attend the emergency room for acute asthma

BACKGROUND

The use of educational and behavioural interventions in the management of chronic asthma have a strong evidence base. There may be a role for educative interventions following presentation in an emergency setting in adults.

OBJECTIVES

To assess the effectiveness of educational interventions administered following an acute exacerbation of asthma leading to presentation in the emergency department.

SEARCH STRATEGY

We searched the Cochrane Airways Group trials register. Study authors were contacted for additional information. Searches are current to November 2006.

SELECTION CRITERIA

Randomised, parallel group trials were eligible if they recruited adults (> 17 years) who had presented at an emergency department with an acute asthma exacerbation. The intervention of interest was any educational intervention (for example, written asthma management plan).

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trial quality and extracted data. Study authors were contacted for additional information.

MAIN RESULTS

Twelve studies involving 1954 adults were included. Education significantly reduced subsequent admission to hospital (relative risk 0.50; 95% confidence interval 0.27 to 0.91); however, did not significantly reduce the risk of re-presentation at emergency departments (ED) the study follow up (relative risk 0.69; 95% confidence interval 0.40 to 1.21). The lack of statistically significant differences between asthma education and control groups in terms of peak flow, quality of life, study withdrawal and days lost were hard to interpret given the low number of studies contributing to these outcomes. One study from the early 1990s measured cost and found no difference for total costs and costs related to physician visits and admissions to hospital. If data were restricted to emergency department treatment, education led to lower costs than control.

AUTHORS' CONCLUSIONS

This review found that educational interventions applied in the emergency department reduce subsequent asthma admissions to hospital. The interventions did not significantly reduce ED re-presentations; while the trend in effect favours educational interventions, the pooled results were not statistically significant. The impact of educational intervention in this context on longer term outcomes relating to asthma morbidity is unclear. Priorities for additional research in this area include assessment of health-related quality of life, lung function assessment, exploration of the relationship between socio-economic status and asthma morbidity, and better description of the intervention assessed.

Asthma control in the Asia-Pacific region: the Asthma Insights and Reality in Asia-Pacific Study

BACKGROUND

Few data on asthma management are available for the Asia-Pacific region.

OBJECTIVE

This study examined asthma symptoms, health care use, and management in the Asia-Pacific region.

METHODS

We performed a cross-sectional survey, followed by administration of a questionnaire in a face-to-face setting in the respondents' homes in their language of choice. Urban centers in 8 areas were surveyed: China, Hong Kong, Korea, Malaysia, The Philippines, Singapore, Taiwan, and Vietnam.

RESULTS

A population sample of 3207 respondents with physician-diagnosed asthma was identified by screening 108,360 households. Daytime asthma symptoms were reported by 51.4% of respondents, and 44.3% reported sleep disturbance caused by asthma in the preceding 4 weeks. At least 2 in every 5 respondents (43.6%) had been hospitalized, attended a hospital emergency department, or made unscheduled emergency visits to other health care facilities for treatment of asthma during the previous 12 months. Overall, 15.3% of respondents reported that they had required admission to the hospital for asthma treatment. Asthma severity correlated with the frequencies of hospitalizations and emergency visits for asthma in the past year. Even in those patients with severe persistent asthma, 34.3% regarded their disease as being well or completely controlled. Current use of an inhaled corticosteroid was reported by only 13.6% of respondents, and 56.3% used quick-relief bronchodilators. Absence from school and work in the past year was reported by 36.5% of children and 26.5% of adults.

CONCLUSION

As reported for other regions, current levels of asthma control in the Asia-Pacific region fall markedly short of goals specified in international guidelines for asthma management.

Does patient knowledge affect the colorectal cancer risk in ulcerative colitis?

OBJECTIVES

Formal efforts to improve patient education are associated with fewer disease complications in a number of conditions. The possible relationship between knowledge about ulcerative colitis and its cancer risk, and the development of colorectal cancer using a previously developed and validated instrument-the Crohn's and colitis knowledge (CCKNOW) score-were investigated.

METHODS

The 24 item CCKNOW questionnaire was mailed to patients known to have developed colorectal cancer as a complication of ulcerative colitis (cases) and to colitics from the Leicestershire inflammatory bowel disease patient database who had not developed cancer (controls).

RESULTS

The mean (SD) CCKNOW scores for cases was 8.21 (3.02) and for controls was 8.27 (4.3). These scores did not differ significantly between cases and controls (difference 0.06, 95% confidence interval (CI) -1.7 to 1.5, p=0.9). There were four times as many members of the National Association of Crohn's and Colitis (NACC) in the control group compared with the cancer group and patients who are members of NACC achieve statistically significantly higher scores than non-members (11.6 v 7.8, p=0.05, 95% CI -0.1 to 7.6). However, after adjusting for NACC membership, the CCKNOW score did not appear to be associated with having developed cancer (odds ratio 1.04, 95% CI 0.92 to 1.18, p=0.5).

CONCLUSIONS

The CCKNOW scores were comparable in cases and controls. Thus, in a retrospective study, no evidence has been demonstrated of an association between patient knowledge and the risk of developing colorectal cancer in patients with ulcerative colitis. However, knowledge may have been increased in cases as a direct result of having had colorectal cancer as a complication of ulcerative colitis.

Educação de pacientes com asma: atuação do enfermeiro

Introdução: Programas de educação em asma levam a melhor controle da asma e são uma das recomendações dos consensos. Os programas devem incluir uma enfermeira no grupo educacional que aplicará o programa estruturado. A proposta da intervenção é mudar a vida diária do paciente e sua família e melhorar o controle da doença e qualidade de vida. Objetivo: Padronizar e aplicar um modelo estruturado de pós-consulta, como parte de atendimento multidisciplinar dentro de um programa educativo para pacientes asmáticos em um ambulatório de um hospital público e acompanhamento das mudanças no conhecimento da asma e qualidade de vida. Método: Estudo longitudinal, prospectivo, com duração de seis meses, realizado no ambulatório de Pneumologia do Hospital São Paulo (Unifesp/EPM), dentro de um programa de educação para pacientes asmáticos, em que foram agendadas seis consultas, com intervalo de quatro semanas, com os seguintes temas: o que é asma, medicações de alívio e prevenção, diário de sintomas e escore de dispnéia, uso correto do aerossol, discussão dos fatores desencadeantes e profilaxia, e também reconhecer os sinais de descontrole da asma. Um modelo padronizado do questionário de conhecimentos sobre asma e outro sobre qualidade de vida foram aplicados no início, durante e no final do estudo. Resultados: 26 asmáticos foram acompanhados por seis meses e mostraram melhora significante na identificação dos problemas relacionados ao manejo da asma, como também nos índices de qualidade de vida. Conclusão: O modelo de atendimento, como também as técnicas de treinamento, foram adequadas e úteis no desenvolvimento de um programa educativo estruturado para pacientes asmáticos.

Evaluation of long-term efficacy of an asthma education programme in an out-patient clinic

The aim of the present study was to evaluate long-term efficacy of a patient education programme in an asthma out-patient clinic. The study included two groups. Educational group consisted of 25 patients who were given special education for one year. Usual care group included 27 patients who were not given special education. All patients were evaluated after 3 years follow-up period. Mean per cent asthma knowledge score (KS%), mean per cent demonstration score (DS%), daytime and nighttime symptom scores, Aas score, and pulmonary function tests were measured. The asthma-quality-of-life assessment was performed. The rate of application to emergency room and admission to hospital for last 1 year had been calculated. KS% was higher in educational group than in usual care group (P < 0.001). Daytime score was 0.3 +/- 0.6 in educational group and was 0.8 +/- 1.2 in usual care group (P = 0.08). Nighttime symptom score was found to be 0.5 +/- 0.9 and 0.9 +/- 1.3, respectively (P = 0.07). Usual care group had higher Aas score compared to educational group (P = 0.048). The total score of quality of life was 197.1 +/- 17.8 in educational group and was 176.7 +/- 33.7 in usual care group (P = 0.009). While none of the patients had emergency room application and hospital admission in educational group, seven patients had 21 emergency room application (P = 0.01) and four patients had four hospital admissions in usual care group. Additional short-acting inhaled beta-2 agonist usage was found lower in the educational group (P = 0.068). In conclusion, proper drug use and usual care of patients are not sufficient for asthma treatment. Patient education is an important component of therapy in asthma patients. For a life with optimum standards, in addition to these factors, patient education must be accepted first by doctors and then by patients.

Evaluation of an asthma management program for Chinese children with mild-to-moderate asthma in Hong Kong

There is inconclusive evidence on the efficacy of outpatient clinic-based asthma management programs (AMP) in children. We hypothesized that an AMP based on key symptoms could improve outcome measures of asthma in Chinese children in Hong Kong. This study involved an outpatient clinic-based prospective cohort of Chinese children with asthma. Each patient received one 2-hr session of AMP which was conducted by a pediatric nurse specialist. Asthma outcomes were measured at baseline and at 6 and 12 months after completion of AMP. Demographic data, family history of allergic diseases, and changes in inhaled steroid therapy were also recorded. A total of 106 asthmatic children were enrolled, and they showed a significant decrease in nocturnal cough, wheezing attacks, and subjective assessment of severity at 6 and 12 months following participation in AMP, compared with their baseline status. Acute asthmatic attacks, unscheduled outpatient attendance, emergency room visits, school absenteeism, and number and duration of hospitalizations were also reduced during the follow-up period. Significantly more (21%) children were reported to use inhaled beclomethasone at the end of the study. Nocturnal cough, wheeze, and symptoms due to rhinitis improved significantly after AMP. In conclusion, our cohort of Chinese children with mild-to-moderate asthma used significantly more inhaled corticosteroids and practiced more measures to control house dust mites at the end of the 1-year treatment period. The main reason for better asthma control appeared to be related to the increased use of inhaled steroids, although some additional decrease in nocturnal cough, wheeze, and allergic rhinitis was found after adjusting for the use of inhaled corticosteroids.

The effect of telepharmacy counseling on metered-dose inhaler technique among adolescents with asthma in rural Arkansas

The increased prevalence, morbidity, mortality, and health costs associated with asthma among children suggest the need for accessible asthma education. This study examined the effect of telepharmacy counseling, using interactive compressed video, on metered-dose inhaler (MDI) technique and patient satisfaction among adolescents with asthma in rural Arkansas. The telepharmacy counseling provided accessible education regarding MDI technique for adolescents in this study. Twenty percent of the adolescents who participated had never been shown the appropriate use of an MDI. The study used an experimental design with random assignment of participants to a telepharmacy counseling group (n = 15) or a control group (n = 21). Both groups participated in pre-test, post-test, and 2- to 4-week follow-up assessments for MDI technique and patients satisfaction (follow-up assessment only) via interactive compressed video. Results indicated that from pre-test to follow-up the telepharmacy counseling group showed more improvement in MDI technique than participants in the control group (p < 0.001). There was no significant difference between the telepharmacy counseling group and control group in satisfaction with the instructional sessions (p = 0.132). Both groups had high levels of satisfaction with the telepharmacy sessions. The study findings demonstrated that patient education provided by pharmacists via interactive compressed video was superior to education provided via written instructions on an inhaler package insert. Interactive compressed video is an effective medium for teaching and improving MDI technique in this rural, adolescent, predominantly African-American population.

Asthma inhalation delivery systems: the patient's viewpoint

International guidelines for asthma management state that inhalation is the preferred route of drug delivery. Consequently, it is important to select an appropriate delivery device and to take account of a patient's preference and lifestyle, as incorrect inhaler use may lead to treatment failure. A large number of devices are available from which to select, but it may be difficult for healthcare professionals to provide guidance to the patient unless they are familiar with the characteristics and correct use of each device. Many factors affect the success of a device in a patient's hands: the device's features; the patient's psychosocial status, cultural beliefs, and language skills; and consistent instruction on inhalation technique. Constant education is essential to establish and maintain the patient's confidence in the treatment regimen. It is important that at least one member of the respiratory healthcare team should remain abreast of medical and pharmaceutical developments in the respiratory field. In this way, the choice of delivery device can be reviewed and changed to suit the changing needs of the patient.
