Asthma management and outcomes in Australia: a nation-wide telephone interview survey

Patients' and physicians' attitudes and perception about asthma in the Gulf: A subset analysis from the Asthma Insights and Management Survey in the Gulf and Russia

Background: Asthma is a prevalent disorder in the Gulf region. However, available data concerning asthma control and patients' perception with regard to their disease are still insufficient. Objective: To investigate patients' perception and behavior with regard to the asthma-related burden, the level of asthma control, and asthma management in three Gulf countries. Methods: This study presented a subset analysis of the Asthma Insights and Management survey about the asthma burden and management in the Gulf region and Russia. In this subset analysis, we retrieved the data of the patients from Saudi Arabia, United Arab Emirates, and Kuwait. Results: The current survey's population was composed of 452 patients. One hundred fifty-four patients (34.1%) rated themselves as having poorly controlled asthma, whereas 60.3% of the patients perceived their asthma as completely or well controlled. However, only two patients (0.4%) had controlled asthma according to the global asthma guidelines criteria for asthma control. Most of the patients (67.7%) reported that their asthma got worse when outdoors. Almost 70% of the patients on daily control plus a quick relief regimen reported that their asthma got worse when they were outdoors. Over the past 12 months, 95 patients (21%) reported asthma exacerbation. More than half of the included patients experienced an asthma attack that stopped their activities, whereas 54.2% of the patients were forced to leave work or school due to an asthma attack, and 53.1% had to cancel an appointment or had to go to bed due to the severity of the attack. With concern to asthma management, only 30.5% of the patients were given a lung function test for the assessment of their asthma. A written action plan for asthma treatment was developed by the physician or the practice nurse for only 21.7% of the patients. Conclusion: In the Gulf region, asthma exerts a substantial burden on patients who are affected. Such a burden significantly impacted patients' quality of life.

The influence of self-assessment of asthma control on the Asthma Control Test outcome

OBJECTIVE

The Asthma Control Test (ACT) consists of five items, one of which is self-assessment of asthma control. The goal of this study was to compare the responses to the first four ACT items with the response to the fifth item and determine whether this response affects the final ACT score.

METHODS

Adult asthmatics (n = 417) were recruited from a specialty asthma center in Poland. Clinical data were collected by questionnaire. Spirometry and skin prick tests were performed for clinical evaluation. Asthma control was assessed through the ACT. The cutoff point for uncontrolled asthma was <20 points.

RESULTS

Asthma was uncontrolled in 42.5% of patients. Based upon scores of the first four ACT items, three clusters of patients were identified. Cluster 1 comprised very well-controlled asthmatics [mean (sd) ACT total score 24.7 (0.7)]. Cluster 2 included both controlled and uncontrolled asthmatics [ACT total score 20.1 (2.5)]. Cluster 3 comprised poorly controlled asthmatics [ACT total score 12.1 (2.9)]. Misjudgment of asthma control in the fifth ACT item had no impact on the ACT total score in clusters 1 and 3. In cluster 2, the response to this item caused misclassification in 10.2% of patients.

CONCLUSIONS

In patients with either very well or very poorly controlled asthma, the response to the fifth ACT item did not alter the assignment into the appropriate asthma control group. Only in a small group of patients with a total ACT score of approximately 20 points did the asthma group classification result in either controlled or uncontrolled.

Perception of asthma control among asthmatics seen inChest Clinic at Tertiary Hospital, Addis Ababa, Ethiopia

BACKGROUND

Patient awareness of asthma severity is important for optimal asthma management. However, there is often a discrepancy between physician assessment of asthma control based on guidelines and patient discernment of control. We compared physician and patient perception of asthma control in a clinic population seen at a tertiary hospital in Addis Ababa, Ethiopia.

METHODS

In this cross-sectional study, 182 consecutive patients with a physician diagnosis of asthma seen in Chest Clinic at Tikur Anbessa Specialized Hospital (TASH) between July and December 2015 were studied. Demographics, asthma symptoms, medication use in the past month, and self-perception of asthma control in the past 7 days were obtained from the clinic records. Physician assessed asthma control was based on the GINA asthma symptom control assessment tool. Lung function was measured using a Diagnostic EasyOne Plus model 2001 SN spirometer. The institutional review board approved the study protocol.

RESULTS

Of the 182 subjects, 68.1% were female. The mean age was 52 ± 12 years, and the mean (SD) duration of asthma was 19.4 ± 12.7 years. Forty-four (24.2%) patients had physician determined well-controlled asthma and 138 (75.8%) patients had physician determined partly controlled/uncontrolled asthma. One hundred and fifty-one (83%) patients thought their asthma control was good. However, the degree of concordance between physician evaluation and patient perception of asthma control was low (kappa index = 0.09). On multivariate analysis, self-perceived poor asthma control was associated with any activity limitation due to asthma and inconsistent inhaled corticosteroid use.

CONCLUSION

In our study, the first of its kind in Ethiopia, a high percent of patients with physician determined well-controlled asthma has appropriate perception of their disease state. However, those patients with partly controlled/uncontrolled asthma had poor self-perception of their disease, emphasizing the need for further patient education. These conclusions may be especially useful in the care of asthmatics from other low-income countries.

Non-pharmacological management of adult asthma in Australia: cross-sectional analysis of a population-based cohort study

Aim: To identify the level of non-pharmacological care received by middle-aged adults with current asthma in Australia and to identify its association with clinical measures. Methods: The Tasmanian Longitudinal Health Study (TAHS) is a population-based cohort first studied in 1968 (n = 8583). In 2010, when participants were aged 49 years, a stratified sample enriched for asthma and bronchitis underwent clinical assessments including respiratory questionnaires and lung function testing (n = 836). Current asthma was defined as self-reported asthma symptoms and/or healthcare utilization in the last 12 months. Multivariable linear regression and log-binomial models were used to assess the relevant associations. Results: Of the entire TAHS cohort, 15.6% (95% CI 13.4-18.2%) had current asthma. Of these, 37.9% (95% CI 30.5-45.9%) had seen a general practitioner for their asthma and 16.5% (95% CI 11.5-23.1%) had discussed their asthma with a pharmacist in the last 12 months. Written asthma action plans (AAPs) were reported by 17.9% (95% CI 12.9-23.2%), verbal AAPs by 53.8% (95% CI 45.9-61.6%) and doctor-assessments of inhaler technique by 42.7% (95% CI 35.2-50.5%). Adults with asthma of greater severity were more likely to have received verbal AAPs (p-trend =0.02). In contrast, adults with lower spirometry were more likely to have received verbal AAPs (p = 0.04), written AAPs (p = 0.001) and education on inhaler technique (p = 0.04). Conclusion: Despite an established evidence base and recommendations in local and international guidelines, non-pharmacological asthma management remains sub-optimal in the middle-aged adult asthma population.

Asthma control in adults in the Middle East and North Africa: Results from the ESMAA study

BACKGROUND

Low levels of asthma control are reported in many countries worldwide. Improved knowledge of asthma control in the Middle East and Africa and predictive factors is needed to address this major public healthcare burden.

OBJECTIVE

To assess the level of asthma control in patients attending a routine consultation for asthma in the Middle East and North Africa, and the relationship between level of control and patient and disease characteristics, adherence, and quality of life (QoL).

METHODS

A large-scale cross-sectional epidemiological study (ESMAA: Assessment of Asthma Control in Adult Asthma Population in the Middle East and North Africa) was performed in adults suffering from asthma for at least 1 year and without an acute asthma episode within 4 weeks. Asthma control was assessed per the 2012 GINA guidelines and the ACT questionnaire. QoL and adherence were assessed with the SF-8 and Morisky questionnaires respectively. Predictive factors of asthma control were analysed with univariate and multivariate logistic regressions analyses.

RESULTS

Overall 7236 eligible patients were included in 577 sites between June 2014 and December 2015 (median 10 patients/site). Mean age was 45 years (±14), 57% were female, mean BMI was 28.5 kg/m² (±6.0), and 11% were active smokers. Reliever medication was prescribed in 96% of patients with 65% having fixed-dose combined inhaled corticosteroid plus long-acting beta agonists. Good medication adherence was reported in 24% of patients. Among 7179 patients evaluable for GINA, asthma was controlled in 29.4% (95% CI, 28.4%-30.5%), partly controlled in 29.1% (95% CI, 28.1%-30.2%), and uncontrolled in 41.5% (95% CI, 40.3% to 42.6). The mean global ACT score was 17.8 (±5.0), with 16% of patients considering their asthma as controlled. Poor medication adherence, active smoking, absence of medical insurance, lower level of education, or diagnosis at least 5 years earlier were significantly associated with uncontrolled asthma in multivariate analyses (p < 0.001).

CONCLUSIONS

Asthma control in the Middle East and North Africa is unsatisfactory with less than one-third of asthma patients having controlled disease, highlighting the need to improve treatment access and medication adherence, along with better follow-up and education among healthcare providers and patients.

Opportunities to develop the professional role of community pharmacists in the care of patients with asthma: a cross-sectional study

There are many indications in Australia and globally that asthma management is suboptimal. Ideally, patients need to proactively self-manage the condition with the support of health professionals. Community pharmacists are a highly accessible resource for patients but currently provide inconsistent services. General practitioners also face many barriers to the provision of chronic disease management for asthma patients. The aim of this research was to characterise patients with asthma who present to community pharmacy. The objective was to identify opportunities to develop the role of pharmacists in the context of the primary healthcare setting and in view of the needs of the patients they routinely encounter. The results of a comprehensive survey of 248 patients recruited from community pharmacies indicated there was discordance between patient perceptions of asthma control and actual asthma control. Almost half the patients surveyed had poorly controlled asthma, whereas almost three quarters perceived their asthma to be well or completely controlled. Fewer than 20% of patients were utilising written asthma action plans, and issues around quality use of medicines were identified. The significance of the incongruent perceptions regarding asthma control is that patients are unlikely to proactively seek intervention and support from healthcare professionals. Community pharmacists provide a significant opportunity to address these issues by direct intervention. There is scope to investigate pharmacists preparing written asthma action plans for patients, using software to monitor medication adherence and prescribe on-going medication. To maximise the potential of pharmacists, barriers to practice need to be identified and addressed.

Factors associated with overestimation of asthma control: A cross-sectional study in Australia

OBJECTIVE

To investigate actual and perceived disease control in Australians with asthma, and identify factors associated with overestimation of asthma control.

METHODS

This was a cross-sectional study of Australian adults with asthma, who were recruited via Facebook to complete an online survey. The survey included basic demographic questions, and validated tools assessing asthma knowledge, medication adherence, medicine beliefs, illness perception and asthma control. Items that measured symptoms and frequency of reliever medication use were compared to respondents' self-rating of their own asthma control. Predictors of overestimation of asthma control were determined using multivariate logistic regression.

RESULTS

Of 2971 survey responses, 1950 (65.6%) were complete and eligible for inclusion. Overestimation of control was apparent in 45.9% of respondents. Factors independently associated with overestimation of asthma control included education level (OR = 0.755, 95% CI: 0.612-0.931, P = 0.009), asthma knowledge (OR = 0.942, 95% CI: 0.892-0.994, P = 0.029), total asthma control, (OR = 0.842, 95% CI: 0.818-0.867, P < 0.001), agreement that most medications are addictive (OR = 1.144, 95% CI: 1.017-1.287, P = 0.025), and increased feelings of control over asthma (OR = 1.261, 95% CI: 1.191-1.335), P < 0.001).

CONCLUSIONS

Overestimation of asthma control remains a significant issue in Australians with asthma. The study highlights the importance of encouraging patients to express their feelings about asthma control and beliefs about medicines, and to be more forthcoming with their asthma symptoms. This would help to reveal any discrepancies between perceived and actual asthma control.

Implementation of asthma guidelines to West Australian community pharmacies: an exploratory, quasi-experimental study

OBJECTIVES

Pharmacy assistants are often the first point of contact for patients presenting in community pharmacies. The current role of pharmacy assistants in the supply of asthma-reliever medications (short-acting β-agonists) was identified as a barrier to appropriate guideline-based care. The aim of this research was to devise and evaluate a team-based intervention to formalise the role of pharmacy assistants and to improve asthma guideline-based care in community pharmacy.

DESIGN

A controlled pre-post intervention study was conducted in 336 metropolitan pharmacies located in Perth, Western Australia. Pharmacies were stratified into 2 groups (187 intervention and 149 control) based on known confounders for asthma control. The intervention was designed using a common-sense approach and resources developed included a checklist, videos and web page. Delivery was via workshops (25 pharmacies) or academic detailing (162 pharmacies). Pharmacy practice was assessed preintervention and postintervention via covert simulated patient methodology. Primary outcome measures included patient medical referral, device use demonstration and counselling, internal referral and/or direct involvement of a pharmacist in consultations.

RESULTS

There was a significant increase in patient medical referral in intervention pharmacies from 32% to 47% (p=0.0007) from preintervention to postintervention, while control pharmacies showed a non-significant decrease from 50% to 44% (p=0.22). Device counselling was not routinely carried out at any stage or in any cohort of this research and no significant changes in internal referral were observed.

CONCLUSIONS

Increases in medical referral indicate that asthma guideline compliance can be improved in community pharmacy if implementation employs a team-based approach and involves pharmacy assistants. However, results were variable and the intervention did not improve practice related to device counselling or internal referral/pharmacist involvement. Undertaking more workshops may have improved results. Guideline implementation in community pharmacy should consider the role of pharmacy assistants and how to overcome logistical barriers to pharmacy participation in implementation activities.

Impact of asthma on mortality in older women: An Australian cohort study of 10,413 women

BACKGROUND

Comorbid conditions frequently coexist with asthma in older adults and can alter the natural history of asthma, complicating management and affecting overall prognosis and survival.

OBJECTIVES

This study investigates the impact of asthma on mortality among older women, with a specific interest in influence of comorbidities and social factors on survival of older women with asthma.

DESIGN

Participants were from the Australian Longitudinal Study on Women's Health and were born between 1921 and 1926. Cox proportional hazards were used to evaluate mortality rates for women with and without asthma, after adjustment for comorbidities and other factors.

RESULTS

Of 10,413 women aged 73-78, 829 (8%) reported having been diagnosed by a doctor for asthma. Women with asthma had a higher likelihood of heart disease, hypertension, thrombosis, bronchitis/emphysema, osteoporosis and major illnesses (p < 0.0001). Asthma was associated with increased risk of death (HR = 1.31, 95%CI 1.18-1.45, p < 0.0001). After adjusting for age, demographic factors, comorbidities, risk factors, residential area and social support, women with asthma retained a 17% increased risk of death compared to women without asthma (HR = 1.17, 95%CI 1.03-1.32, p = 0.016).

CONCLUSION

Older women with asthma have a higher rate of mortality compared with other women of the same age. This increased risk of death remains after age, demographic factors, comorbidities, risk factors, residential area and social support have been taken into account.

Asthma control in Australia: a cross-sectional web-based survey in a nationally representative population

OBJECTIVE

To identify patterns of asthma control and treatment in Australian adults with asthma.

DESIGN

Cross-sectional web-based survey, conducted 1-27 November 2012.

PARTICIPANTS

Adults with current asthma, at least 16 years of age, drawn randomly from a web-based panel and weighted to reflect national population proportions for people with asthma.

MAIN OUTCOME MEASURES

Asthma Control Test (ACT) scores; health care utilisation; medication use.

RESULTS

2686 participants completed the survey (57.1% female; median age group, 40-49 years). Mean ACT score was 19.2 (95% CI, 18.9-19.3), with asthma classified as "well controlled" for 54.4% of participants, "not well controlled" for 22.7% and "very poorly controlled" for 23.0%. 60.8% reported using preventer medication (mostly combined inhaled corticosteroid/long-acting β2-agonist) during the previous year. 23.4% had made at least one urgent visit to a general practitioner concerning their asthma, 10.0% at least one emergency department visit. Urgent consultations were more common for "very poorly controlled" than "well controlled" asthma (adjusted odds ratio, urgent GP visits 5.98 [95% CI, 4.75-7.54] and emergency department visits 2.59 [95% CI, 1.91-3.53] respectively). Participants were classified according to asthma symptom control and frequency of preventer medication usage: Those with "well controlled" asthma included Group A (40.0% of participants) who used preventer medication infrequently (less than 5 days a week) or not at all, consistent with mild asthma, and Group B (14.7%), who used it at least 5 days a week. Uncontrolled asthma symptoms were reported by Group C (19.7%) despite regular preventer use, and by Group D (25.7%), who used none or little.

CONCLUSIONS

This study provides the first data about asthma control and its relationship with treatment in a large representative Australian population. The findings highlight significant preventable asthma morbidity in Australia.

Taking Aim at Asthma Around the World: Global Results of the Asthma Insight and Management Survey in the Asia-Pacific Region, Latin America, Europe, Canada, and the United States

BACKGROUND

Asthma, a worldwide health problem, can be controlled if properly diagnosed and managed. Multinational surveys conducted in patients with asthma from 1998 to 2003 indicated that asthma was inadequately controlled. The Asthma Insight and Management (AIM) study represents the largest survey conducted on patients with asthma since 2003.

OBJECTIVE

The objective of this study was to assess findings from the United States (US), Europe and Canada (EUCAN), Latin America (LA), and the Asia-Pacific (AP) region surveys to identify differences and similarities with earlier surveys on patients with asthma.

METHODS

The US, EUCAN, LA, and AP AIM surveys conducted from 2009 to 2011 all used a common set of questions. Responses to these are reported as proportions of patients with asthma for each country individually, and as totals for all regions. Results are presented as mean/median proportions for US, EUCAN, LA, and AP survey populations individually. Global medians and the range of regional response values are also described.

RESULTS

A total of 10,302 patients or parents of adolescents with asthma were interviewed. Approximately one-quarter reported daytime symptoms daily or on most days over the previous 4 weeks. Globally, a median of 67% (range, 27%-88%) of patients perceived their asthma as completely and/or well controlled, but a median of only 9% (range, 0%-29%) of patients had well-controlled asthma using criteria from asthma guidelines. A majority (≥60%) of patients felt that quick-relief medication could be used daily if needed, contrary to guideline recommendations.

CONCLUSIONS

Patients exhibited a lack of knowledge and conviction for treatment recommendations and guidelines that was relatively uniform across the regions, similar to earlier survey findings. These results reveal an ongoing need for improvement in asthma care and education in most populations.

The reliability and utility of spirometry performed on people with asthma in community pharmacies

OBJECTIVE

To investigate the reliability and the utility of spirometry generated by community pharmacists participating in two large asthma intervention trials of 892 people.

METHODS

The Pharmacy Asthma Care Program (PACP) and the Pharmacy Asthma Management Service (PAMS) involved up to four visits to the pharmacy over 6 months for counseling and goal setting. Pharmacists performed spirometry according to ATS/ERS guidelines to inform management. The proportion of A-E, F quality tests, as per EasyOne QC grades, were recorded. Lung function results between visits and for participants referred/not referred to their general practitioner on the basis of spirometry were compared.

RESULTS

Complete data from 2593 spirometry sessions were recorded, 68.5% of spirometry sessions achieved three acceptable tests with between-test repeatability of 150 ml or less (A or B quality), 96% of spirometry sessions included at least one test that met ATS/ERS acceptability criteria. About 39.1% of participants had FEV1/FVC values below the lower limit of normal (LNN), indicating a respiratory obstruction. As a result of the service, there was a significant increase in FEV1 and FEV1/FVC and asthma control. Lung function values were significantly poorer for participants referred to their general practitioner, compared with those not referred, on the basis of spirometry.

CONCLUSIONS

Community pharmacists are able to reliably achieve spirometry results meeting ATS/ERS guidelines in people with asthma. Significant improvements in airway obstruction were demonstrated with the pharmacy services. Pharmacists interpreted lung function results to identify airway obstruction for referral, making this a useful technique for review of people with asthma in the community.

Asthma management self-efficacy in parents of primary school-age children

The aim of this study was to investigate asthma management self-efficacy in parents of primary school-age children with asthma and to explore possible associations between parent asthma management self-efficacy, parent and child characteristics, asthma task difficulty and asthma management responsibility. A cross-sectional descriptive survey of 113 parents was conducted to assess the level of parent asthma management self-efficacy, asthma task difficulty and confidence, asthma responsibility and socio-demographic characteristics. The findings indicate that parents had higher self-efficacy for attack prevention than attack management. Parents had higher self-efficacy for asthma management tasks that are simple, skills based and performed frequently such as medication administration and less confidence and greater difficulty with tasks associated with judgement and decision-making. Multivariate linear regression analysis identified English language, child asthma responsibility and parent education as predictors of higher asthma management self-efficacy, while an older child was associated with lower parent asthma management self-efficacy. The implications of these results for planning and targeting health education and self-management interventions for parents and children are discussed.

Does personality influence how people with asthma manage their condition?

OBJECTIVE

Personality traits have been found to be associated with the management of chronic disease, however, there is limited research on these relationships with respect to asthma. Asthma management and asthma control are often suboptimal, representing a barrier to patients achieving good health outcomes. This explorative study aimed to investigate the relationship between correlates of asthma management and personality traits.

METHODS

Participants completed a postal survey comprising validated self-report questionnaires measuring personality traits (neuroticism, extraversion, openness to experiences, agreeableness, conscientiousness), asthma medication adherence, asthma control and perceived control of asthma. Relationships between asthma management factors and personality traits were examined using correlations and regression procedures.

RESULTS

A total of 77 surveys were returned from 94 enrolled participants. Significant relationships were found between personality traits and (i) adherence to asthma medications, and (ii) perceived control of asthma. Participants who scored high on the conscientiousness dimension of personality demonstrated higher adherence to their asthma medications. Women who scored low on the agreeableness dimension of personality and high on the neuroticism dimension had significantly lower perceived confidence and ability to manage their asthma. No statistically significant associations were found between asthma control and personality traits.

CONCLUSIONS

Three of the five personality traits were found to be related to asthma management. Future research into the role of personality traits and asthma management will assist in the appropriate tailoring of interventional strategies to optimize the health of patients with asthma.

Using scenarios to test the appropriateness of pharmacist prescribing in asthma management

OBJECTIVE

To explore the potential for community pharmacist prescribing in terms of usefulness, pharmacists' confidence, and appropriateness, in the context of asthma management.

METHODS

Twenty community pharmacists were recruited using convenience sampling from a group of trained practitioners who had already delivered asthma services. These pharmacists were asked to complete a scenario-based questionnaire (9 scenarios) modelled on information from real patients. Pharmacist interventions were independently reviewed and rated on their appropriateness according to the Respiratory Therapeutic Guidelines (TG) by three expert researchers.

RESULTS

In seven of nine scenarios (78%), the most common prescribing intervention made by pharmacists agreed with TG recommendations. Although the prescribing intervention was appropriate in the majority of cases, the execution of such interventions was not in line with guidelines (i.e. dosage or frequency) in the majority of scenarios. Due to this, only 47% (76/162) of the interventions overall were considered appropriate. However, pharmacists were deemed to be often following common clinical practice for asthma prescribing. Therefore 81% (132/162) of prescribing interventions were consistent with clinical practice, which is often not guideline driven, indicating a need for specific training in prescribing according to guidelines. Pharmacists reported that they were confident in making prescribing interventions and that this would be very useful in their management of the patients in the scenarios.

CONCLUSIONS

Community pharmacists may be able to prescribe asthma medications appropriately to help achieve good outcomes for their patients. However, further training in the guidelines for prescribing are required if pharmacists are to support asthma management in this way.

Cost-effectiveness of asthma clinic approach in the management of chronic asthma in Australia

OBJECTIVES

To compare cost-effectiveness of an asthma clinic that would provide education, promotion of self-monitoring of symptoms, regular review of treatment by a medical practitioner and a written asthma action plan to current practice in Australia.

METHODS

A decision tree model was used to compare treatment and improved management using asthma clinics under three scenarios: 1) intervention reduces only emergency department visits; 2) in addition, it leads to a reduction in days out of role; and 3) it also reduces unplanned general practitioner visits and hospitalisations. Evidence from existing published studies was used for asthma incidence, duration, treatment practices and health seeking behaviours. Costs for one year were estimated based on an asthma clinic trial in Australia.

RESULTS

The estimated $274 million annual cost of asthma clinics is much greater than the potential cost savings of $11 million resulting from reduced emergency department visits, and an overall potential cost saving of $85 million resulting from decreased GP visits and hospitalisations. The incremental cost-effective ratio (ICER) is $24,000 if a reduction in days out of role is quantified as a health benefit in estimating disability-adjusted life years (DALY). If a potential $85 million in cost-savings from decreased emergency department visits, GP visits and hospitalisation is taken into account, the ICER drops to $17,000 per DALY averted.

CONCLUSIONS

An asthma clinic as an intervention for improving self-management may be cost-effective in Australia if multiple benefits can be achieved.

IMPLICATIONS

A large-scale asthma clinic trial and long-term evaluation of benefits are necessary to obtain stronger evidence on the benefit of asthma clinic approach in Australia.

Prevalence trends in respiratory symptoms and asthma in relation to smoking - two cross-sectional studies ten years apart among adults in northern Sweden

Background

Smoking is considered to be the single most important preventable risk factor for respiratory symptoms. Estimating prevalence of respiratory symptoms is important since they most often precede a diagnosis of an obstructive airway disease, which places a major burden on the society. The aim of this study was to estimate prevalence trends of respiratory symptoms and asthma among Swedish adults, in relation to smoking habits. A further aim was to estimate the proportion of respiratory symptom and asthma prevalence attributable to smoking.

Methods

Data from two large-scale cross-sectional surveys among adults performed in northern Sweden in 1996 and 2006 were analysed. Identical methods and the same questionnaire were used in both surveys. The association between smoking, respiratory symptoms and asthma was analysed with multiple logistic regression analyses. Changes in prevalence of respiratory symptoms and asthma from 1996 to 2006 were expressed as odds ratios. Additionally, the population attributable risks of smoking were estimated.

Results

The prevalence of most respiratory symptoms decreased significantly from 1996 to 2006. Longstanding cough decreased from 12.4 to 10.1%, sputum production from 19.0 to 15.0%, chronic productive cough from 7.3 to 6.2%, and recurrent wheeze from 13.4 to 12.0%. Any wheeze and asthmatic wheeze remained unchanged. This parallels to a decrease in smoking from 27.4 to 19.1%. In contrast, physician-diagnosed asthma increased from 9.4 to 11.6%. The patterns were similar after correction for confounders. All respiratory symptoms were highly associated with smoking, and the proportion of respiratory symptoms in the population attributed to smoking (PAR) ranged from 9.8 to 25.5%. In 2006, PAR of smoking was highest for recurrent wheeze (20.6%).

Conclusions

In conclusion, we found that respiratory symptoms, in particular symptoms common in bronchitis, decreased among adults in northern Sweden, parallel to a decrease in smoking from 1996 to 2006. In contrast, the prevalence of physician-diagnosed asthma increased during the same time-period. Up to one fourth of the respiratory symptom prevalence in the population was attributable to smoking.

Prevalence and severity of asthma and related symptoms in 6- to 7-year-old schoolchildren of Rio de Janeiro using of the ISAAC questionnaire by telephone survey

OBJECTIVE

To evaluate the prevalence and severity of asthma and its association with sex in 6- to 7-year-old schoolchildren from the city of Rio de Janeiro (RJ), obtained by a telephone survey.

METHODS

A cross-sectional study using the International Study of Asthma and Allergies in Childhood (ISAAC) Written Questionnaire for Asthma adapted and validated by telephone interviews was conducted. The random sample was recruited systematically, without replacement, taking into account the proportion of school classes and students in each regional coordination of the Municipal Secretariat of Education, which supplied the students' telephone numbers. The data were collected by a polling company from May to July 2010. Prevalence ratios (PRs) and 95% confidence intervals (95% CI) were compared using the difference in proportions test suitable for large samples to analyze the association between asthma and sex.

RESULTS

In total, 3216 interviews from parents/caregivers of children were analyzed; 51.4% of the children were males. Mothers were the primary respondents (71.9%). The prevalence rates of "wheezing ever" and "wheezing in the last 12 months" were 52.2% and 20.9%, respectively, and were significantly higher among boys (PR: 1.10, 95% CI: 1.03-1.18 and PR: 1.27, 95% CI: 1.10-1.45). The same pattern was observed for "asthma ever" (PR: 1.44, 95% CI: 1.12-1.85) and for "severe asthma" (PR: 1.42, 95% CI: 1.11-1.82).

CONCLUSION

The prevalence of asthma was high among RJ's students. Most of the indicators of the disease were more prevalent among boys. Our results were similar to those observed in other Brazilian and international centers using the traditional ISAAC protocol. The use of this method can be an alternative for epidemiological studies of childhood asthma especially in areas where the telephone coverage is high.

Proposed model for Iranian national system of registration of allergy and asthma

Introduction:

Asthma and allergies in addition to demanding social costs–the economic community, one of the major causes of morbidity and mortality in the world is considered. In the last decade in Iran despite the positive developments in many areas of health records into categories based asthma and allergy international standards, less attention has been paid. Improving the quality of care system, identifying groups at risk of asthma and allergies, control plan, prevention and assessment of asthma and allergies due to possible that when allergy and asthma information registration system and create the complete and timely data to be collected. Considering now an efficient national system of registration allergy and asthma that can meet the health needs can no need for this study was felt.

Materials and Methods:

This study, study–the comparison was done in the years 2010-2011. In this research, using library resources, information networks and consultations with experts inside the country gathered on the main axis and branches of national registration system, asthma and allergies in American countries–Australia and England were examined and given economic conditions, cultural and geographical themes for our records system, the axes were proposed objectives, structure, data elements, standard registration process?

House dust allergy and immunotherapy

HDM allergy is associated with asthma, allergic rhinitis and atopic dermatitis. In many countries childhood asthma is predominantly found in HDM-allergic children with their probability of developing disease being proportional to their IgE antibody titers and the early development of Th2 responses. While the pathogenesis is complex and increasingly linked to infection the immunologically-based allergen immunotherapy and anti-IgE antibody therapy are highly beneficial. Immunotherapy could be a short-term treatment providing lifelong relief but the current regimens depend on repeated administration of allergen over years. Immunological investigations point to a contribution of responses outside the Th2 pathway and multiple potential but unproven control mechanisms. Over half of the IgE antibodies are directed to the group 1 and 2 allergens with most of remainder to the group 4, 5, 7 and 21 allergens. This hierarchy found in high and low responders provides a platform for introducing defined allergens into immunotherapy and defined reagents for investigation.

Validity and reproducibility of the asthma core International Study of Asthma and Allergies in Childhood (ISAAC) written questionnaire obtained by telephone survey

OBJECTIVE

To assess the reproducibility and validity of the International Study of Asthma and Allergies in Childhood (ISAAC) asthma written questionnaire (IAWQ) for 6- to 7-year-old children administered to their parents/caregivers through a telephone interview.

METHODS

Our study included 100 children selected from three health units in Rio de Janeiro, Brazil. In total, 50 asthmatic and 50 non-asthmatic children were evaluated; all participants were required to own a household telephone line. Initially, telephone interviews were conducted with the parents/caregivers using the IAWQ. After 2 weeks, parents/caregivers were invited to complete the IAWQ under supervision provided by the researchers. After fifteen days, the telephone interviews were repeated. The reproducibility between the two telephone interviews was assessed using kappa (κ) coefficients; the construct validity was assessed by comparing the answers obtained in the initial telephone interview in both groups according to the clinical diagnosis of asthma performed by a specialist using sensitivity and specificity coefficients.

RESULTS

Overall, data from 75 children (39 asthmatics) were analyzed, as 25 patients were excluded from the study (11 did not answer phone calls and the responding parents/caregivers for 14 patients were not the same in all study phases). Perfect agreement was observed for the indicator "wheezing in the last 12 months" (κ = 1), while substantial agreement was observed for the "wheezing with exercise," "speech limited by wheezing," and "asthma ever" indicators (κ range, 0.7-0.8). The sensitivity and specificity for "wheezing within the last 12 months" were 64.1% (95% confidence interval (CI), 47.2-78.8) and 88.9% (95% CI, 73.9-96.9), respectively. For the "asthma ever" indicator, the sensitivity and specificity were 87.2% (95% CI, 77.6-95.7) and 100% (95% CI, 90.3-1), respectively. Questionnaire specificity was high for all asthma severity indicators.

CONCLUSIONS

The IAWQ for children aged 6-7 years adapted for telephone interviews showed good reproducibility and adequate validity with an ability to distinguish between asthmatic and non-asthmatic participants. Thus, this method could be utilized in epidemiological studies on childhood asthma in locations where telephone lines are available.

Over-the-counter β2-agonist purchase versus script: a cross-sectional study

BACKGROUND

Purchase of short-acting β(2)-agonist (SABA), but not anti-inflammatory asthma medication, is permitted in Australia without a doctor's prescription. This has been associated with worse asthma outcomes. We sought to compare the asthma outcomes between those purchasing SABA with and without a doctor's prescription.

METHODS

DESIGN

Cross-sectional study, using stratified randomisation of pharmacies.

SETTING

43 pharmacies in Victoria, Australia.

PARTICIPANTS

Up to 10 consecutive adults purchasing β(2)-agonists were recruited from each pharmacy, with 316 adults in total.

OUTCOME MEASURES

Participants underwent spirometry and questionnaires on respiratory health, asthma control, Quality of Life and medication adherence. Asthma severity was determined by GINA medication step. Regression analyses were performed that allowed for clustering by pharmacy.

RESULTS

Of 316 individuals recruited (65% participation rate), 191 (60%) purchased a β(2)-agonist with a prescription. Purchase of SABA without prescription was not associated with worse asthma outcomes or lung function. Mean (±SD) asthma control score (ACQ) was 1.65 ± 1.03; only 63 (20%) had well-controlled asthma (ACQ < 0.75). Anti-inflammatory asthma medication was owned by 188 (60%) of participants, of whom 157 (83%) reported using this in the last 7 days. There was no correlation between medication adherence scores and asthma control. Forty-seven participants (15%) had an FEV(1) below 80% predicted and did not own an anti-inflammatory asthma medication.

CONCLUSION

Purchase of SABA without prescription was not associated with worse asthma outcomes in Australia. Although many patients reported symptoms of asthma, this did not appear to be associated with reported adherence to anti-inflammatory asthma medication.

[Health survey in Campinas, São Paulo State, Brazil (ISACamp): comparison of estimates according to ownership of a residential telephone line]

The study assesses differences in socio-demographic, lifestyle, and health-related characteristics among adults with and without residential telephone lines using data from a health survey in Campinas, São Paulo State, Brazil, (2008-2009), through a population-based cross-sectional survey that included 2,637 adults (18 years and older). Descriptive statistics, chi-square tests, prevalence, and 95% confidence intervals were used in the analysis. Estimates were also made of the bias associated with non-coverage of the population without telephones before and after adjusting for post-stratification. The impact of bias on the confidence intervals was assessed by the bias ratio. Some 76% of respondents owned residential telephone lines. Except for marital status, differences were observed in socio-demographic data according to ownership of residential telephones. After post-stratification adjustment, there was a decrease in bias estimates for variables associated with ownership of telephone lines. However, except for osteoporosis, post-stratification adjustment was insufficient to correct the non-coverage bias.

Using the community pharmacy to identify patients at risk of poor asthma control and factors which contribute to this poor control

BACKGROUND

Although asthma can be well controlled by appropriate medication delivered in an appropriate way at an appropriate time, there is evidence that management is often suboptimal. This results in poor asthma control, poor quality of life, and significant morbidity.

METHODS

The objective of this study was to describe a population recruited in community pharmacy identified by trained community pharmacists as being at risk for poor asthma outcomes and to identify factors associated with poor asthma control. It used a cross-sectional design in 96 pharmacies in metropolitan and regional New South Wales, Victoria, Queensland, and Australian Capital Territory in Australia. Community pharmacists with specialized asthma training enrolled 570 patients aged ≥18 years with doctor-diagnosed asthma who were considered at risk of poor asthma outcomes and then conducted a comprehensive asthma assessment. In this assessment, asthma control was classified using a symptom and activity tool based on self-reported frequency of symptoms during the previous month and categorized as poor, fair, or good. Asthma history was discussed, and lung function and inhaler technique were also assessed by the pharmacist. Medication use/adherence was recorded from both pharmacy records and the Brief Medication Questionnaire (BMQ).

RESULTS

The symptom and activity tool identified that 437 (77%) recruited patients had poor asthma control. Of the 570 patients, 117 (21%) smoked, 108 (19%) had an action plan, 372 (69%) used combination of inhaled corticosteroid (ICS)/long-acting β(2)-agonist (LABA) medications, and only 17-28% (depending on device) used their inhaler device correctly. In terms of adherence, 90% had their ICS or ICS/LABA dispensed <6 times in the previous 6 months, which is inconsistent with regular use; this low adherence was confirmed from the BMQ scores. A logistic regression model showed that patients who smoked had incorrect inhaler technique or low adherence (assessed by either dispensing history or BMQ) and were more likely to have poor control.

CONCLUSION

Community pharmacists were able to identify patients with asthma at risk of suboptimal control, and factors that contributed to this were elicited. This poorly controlled group that was identified may not be visible or accessible to other health-care professionals. There is an opportunity within pharmacies to target poorly controlled asthma and provide timely and tailored interventions.

Perceived feasibility of a community pharmacy-based asthma intervention: a qualitative follow-up study

WHAT IS KNOWN AND OBJECTIVE

Asthma is a National Health Priority Area in Australia; however, recent evidence suggests that its management remains suboptimal. Community pharmacists are in a unique position to help patients manage asthma, and a number of community pharmacy-based asthma interventions have demonstrated effectiveness with improved patient outcomes. This study aimed to explore the views of general practitioners (GPs), community pharmacists and patients towards a pharmacy-based intervention that saw patients with poorly managed asthma supplied with educational material and referred to their GP for an asthma management review.

METHODS

A qualitative follow-up study of participants who had been involved in the intervention was conducted. A sample of six GPs, 10 community pharmacists and 10 patients participated in semi-structured face-to-face interviews. Data were analysed using interpretive phenomenology.

RESULTS AND DISCUSSION

General practitioners accepted the intervention process if they had positive relationships with pharmacists. There was also some hesitance of GPs towards the intervention, related to a perceived encroachment on their area of responsibility and a perceived conflict of interest of pharmacists in providing health care. GPs indicated the need to be more involved with the intervention process, and expressed that patients were rarely forthcoming about problems with their asthma. Community pharmacists felt that patients can be apathetic about asthma and often fail to seek medical advice. The intervention was implemented very easily, with minimal disruptions to the pharmacists' workflow, and pharmacists suggested that it would be better if GPs were more involved with the intervention process. Patients' general satisfaction with pharmacy services was high, but their expectations were quite low. Although there was an appreciation by patients of community pharmacists' interest in their health, this did not necessarily translate into appointments with GPs for an asthma management review. The reason for this related primarily to patients' under-estimation of their asthma severity.

WHAT IS NEW AND CONCLUSION

A wider rollout of the asthma intervention, with an improved process for involving GPs, would be feasible and well accepted. Further research should determine the best approach in influencing patients' perceptions of asthma control and whether these perceptions are amenable to a more intensive educational intervention. This could result in more efficient asthma interventions, translating to improved patient outcomes.

The role of parents in managing asthma in middle childhood: an important consideration in chronic care

Asthma is a significant illness for Australian children and their families. In childhood, parents have the primary responsibility for managing asthma on a day-to-day basis, and therefore understanding the management of asthma by parents is important to nursing practice. Middle childhood (5-12 years) is an important time in the lives of children and families with asthma, as children commence school and spend increasing amounts of time away from direct parental care. In order to manage asthma during middle childhood, parents need to understand asthma as an illness, understand the treatment of asthma, be able to monitor and respond to changes in condition, manage other carers, manage asthma in the context of family life and guide the development of self-management responsibility in their child with asthma. While the scope of parent management in terms of asthma knowledge and treatment has been well explored in the literature, less is known about the process by which parents support the development of self-management responsibility in children with asthma.

The Asthma Insights and Reality in the Maghreb (AIRMAG) study: perspectives and lessons

Asthma is the most frequently encountered allergic respiratory disease, and one that has a potentially serious impact on patients' functioning and well-being. From a public health perspective, it is important to collect data on the prevalence, burden and management of asthma in order to improve understanding of the pathogenesis of asthma and to ensure that national healthcare policies are adapted and appropriate. In this respect, the different AIR surveys, which have collected standardised data on asthma in the general population of a large number of countries around the world, have made an important contribution. The latest of these surveys is the AIRMAG survey, performed in the three Maghreb countries of Algeria, Morocco and Tunisia. In these countries, the prevalence of asthma (3.4% to 3.9%) is in the low to moderate range. This is consistent with rates observed elsewhere in the Mediterranean basin. Nonetheless, the prevalence of asthma in the Maghreb may be expected to rise in the future as populations become more urbanized and adopt a more 'Westernized' lifestyle. Indeed the prevalence of asthma is already higher in the urban coastal regions of these countries than in the more rural mountainous and desert regions. Asthma control in the Maghreb is relatively poor compared to other regions evaluated in previous AIR studies, with control being unacceptable in around three-quarters of respondents. Although part of the explanation may reside in limited access to care, treatment rates for inhaled corticosteroids (26.1% of adults and 29.1% of children) were no worse than those reported in previous AIR studies. On the other hand, asthma monitoring through regular follow-up visits, home flow-meter use and preparation of individualised asthma management plans was in general unsatisfactory. In addition, awareness of asthma in the general population of the Maghreb countries was low. Education measures directed at the patient, together with programmes directed at the physician to ensure systematic monitoring and the use of a 'treat to target' approach to therapy, could do much to increase quality of life and minimise restrictions on activities in patients with asthma in the Maghreb.

Prevalence of asthma in North Africa: the Asthma Insights and Reality in the Maghreb (AIRMAG) study

BACKGROUND

Bronchial asthma is the most frequent chronic respiratory disease in both adults and children. The prevalence and burden of asthma vary considerably between different regions of the world. Information on asthma in Africa is fragmentary and relatively old.

OBJECTIVE

The objective of this cross-sectional epidemiological survey was to determine the prevalence and burden of asthma in the North African countries of Algeria, Morocco and Tunisia using the methodology developed in the Asthma Insights and Reality (AIR) programme.

METHODS

A general population sample was generated using a stratified sampling method based on randomly-generated lists of telephone numbers. The target sample consisted of 10,000 households in each country, which were contacted by telephone. A structured interview was proposed. Two screening questions were asked to identify subjects with asthma. Subjects who met these criteria were then questioned in more detail about their asthma.

RESULTS

Of 30 350 households contacted, 1090 subjects with asthma were identified of whom 872 provided complete data. The age- and gender-adjusted prevalence of asthma was 3.45% [95% CI: 3.09 3.80%] in Algeria, 3.89% [95% CI: 3.52 4.27%] in Morocco and 3.53% [95% CI: 3.18 3.89%] in Tunisia. Prevalence was highest in children and older adults, and in urban areas. Annual incidence rates ranged between 28/10,000 in Tunisia and 46/10,000 in Algeria. 74.3% of adults reported being handicapped by their asthma all or most of the time, 26.4% reported a visit to a hospital emergency department in the previous year and 23.9% absence from work or school due to asthma. 48.0% reported that their sleep was very or quite disturbed by asthma.

CONCLUSIONS

The prevalence of asthma in the Maghreb countries is moderate, but its impact is high.

Do small group workshops and locally adapted guidelines improve asthma patients' health outcomes? A cluster randomized controlled trial

OBJECTIVE

To improve health outcomes of children and adolescents with asthma using a multifaceted intervention for GPs.

METHODS

The design of the study was a cluster randomized controlled trial. GPs were randomized at a practice level in general practice clinics in Melbourne, Australia. Participants were children/adolescents aged 2-14 years with asthma and their caregivers identified from the medical records of participating clinics. Questionnaires were completed by 411 at baseline and 341 at follow-up. The intervention arm (n = 18 GPs) participated in a small group asthma education programme and was provided with locally adapted paediatric asthma guidelines. One control arm (n = 18 GPs) received only the adapted paediatric asthma guidelines, while the other control arm (n = 15 GPs) received an unrelated educational intervention. The outcome measures of the study were children/adolescents and caregivers completed questionnaires about asthma management and control, asthma knowledge and quality of life at recruitment and 6 months later. Ownership of a written asthma action plan (WAAP) was the primary outcome.

RESULTS

There was no evidence for changes in ownership of WAAPs between the three study arms. Adolescents in the intervention group reported an improvement in quality of life subscale score 'positive effects' (mean difference = 2.64, P = 0.01), but there was no evidence for an effect of the intervention on other study outcomes among the three study arms.

CONCLUSIONS

The intervention was associated with some improvement in quality of life for adolescents. However, overall, the intervention did not translate into increased ownership of WAAPs, control of asthma or improved quality of life.

Using fractional exhaled nitric oxide to guide asthma therapy: design and methodological issues for ASthma TReatment ALgorithm studies

BACKGROUND

Current asthma guidelines recommend treatment based on the assessment of asthma control using symptoms and lung function. Noninvasive markers are an attractive way to modify therapy since they offer improved selection of active treatment(s) based on individual response, and improved titration of treatment using markers that are better related to treatment outcomes.

AIMS

To review the methodological and design features of noninvasive marker studies in asthma.

METHODS

Systematic assessment of published randomized trials of asthma therapy guided by fraction of exhaled nitric oxide(FENO).

RESULTS

FENO has appeal as a marker to adjust asthma therapy since it is readily measured, gives reproducible results, and is responsive to changes in inhaled corticosteroid doses. However, the five randomised trials of FENO guided therapy have had mixed results. This may be because there are specific design and methodological issues that need to be addressed in the conduct of ASthma TReatment ALgorithm(ASTRAL) studies. There needs to be a clear dose response relationship for the active drugs used and the outcomes measured. The algorithm decision points should be based on outcomes in the population of interest rather than the range of values in healthy people, and the algorithm used needs to provide a sufficiently different result to clinical decision making in order for there to be any discernible benefit. A new metric is required to assess the algorithm performance, and the discordance:concordance(DC) ratio can assist with this.

CONCLUSION

Incorporating these design features into future FENO studies should improve the study performance and aid in obtaining a better estimate of the value of FENO guided asthma therapy.

Benefits of fixed-dose combination therapy with inhaled corticosteroids and long-acting bronchodilators as initial maintenance therapy in the management of asthma

BACKGROUND AND OBJECTIVE

Revised Australian guidelines for asthma management were released by the National Asthma Council (NAC) in 2006. One area where clinical opinion and trial data have changed recently concerns the place of fixed-dose combination (FDC) therapy with inhaled corticosteroid (ICS) and long-acting beta(2)-agonists as initial maintenance therapy.

METHODS

A systematic review of the literature commissioned by the NAC and undertaken by the University of Tasmania addressed several questions, including whether there was evidence for the use of FDC therapy as first-line asthma treatment in steroid-naïve patients.

RESULTS

Nineteen relevant studies were identified, from which 20 comparisons contributed to the analyses. The definition of steroid-naïve ranged from no ICS therapy over the preceding 1 month to no ICS therapy ever. FDC therapy was effective in subjects who were steroid-naïve and was more effective than an equivalent dose of ICS, irrespective of the definition of steroid-naïvety. Compared with ICS alone, FDC therapy increased mean FEV(1) by 140 mL, mean morning PEF by 21 L/min and mean evening PEF by 20 L/min. There was a mean increase of 9.8% in symptom-free days, associated with a greater reduction in rescue medication use of -0.12 puff/24 h. FDC therapy was not superior to ICS alone for prevention of withdrawals or exacerbations requiring systemic corticosteroids. Adverse events were similar for FDC therapy and ICS, whether ICS were administered at the same or an increased dose.

CONCLUSIONS

FDC therapy is effective as first-line treatment in steroid-naïve subjects and is superior to ICS alone for most outcomes, irrespective of the period of time since last exposure to ICS.

Pharmacist-initiated general practitioner referral of patients with suboptimal asthma management

OBJECTIVE

To assess the impact of an intervention initiated by community pharmacists, involving the provision of educational material and general practitioner (GP) referral, on asthma knowledge and self-reported asthma control and asthma-related quality of life (QOL) in patients who may have suboptimal management of their asthma, as evidenced by pharmacy dispensing records. Setting Community pharmacies throughout Tasmania, Australia.

METHODS

Forty-two pharmacies installed a software application that data mined dispensing records and generated a list of patients with suboptimal asthma management, as indicated by having three or more canisters of inhaled short-acting beta-2-agonists dispensed in the preceding 6 months. Identified patients were randomised to an intervention or control group. At baseline, intervention patients were mailed intervention packs consisting of a letter encouraging them to see their GP for a review, educational material, asthma knowledge, asthma control and asthma-related QOL questionnaires, and a letter with a dispensing history to give to their GP. Pharmacists were blinded to the control patients' identities for 6 months, after which time intervention patients were sent repeat questionnaires, and control patients were sent intervention packs.

MAIN OUTCOME MEASURES

Asthma knowledge, asthma control and asthma-related QOL scores.

RESULTS

Thirty-five pharmacies completed the study, providing 706 intervention and 427 control patients who were eligible to receive intervention packs. Intervention patients' asthma control and asthma-related QOL scores at 6 months were significantly higher compared to the control patients (P < 0.01 and P < 0.05, respectively) and to the intervention patients' baseline scores (P < 0.001 and P < 0.05, respectively). Symptom-related QOL was significantly higher compared to the control patients (P < 0.01) and activities-related QOL significantly improved compared to baseline (P < 0.05). No significant change was observed in asthma knowledge.

CONCLUSION

The results suggest that community pharmacists are ideally placed to identify patients with suboptimal asthma management and refer such patients for a review by their GP. This type of collaborative intervention can significantly improve self-reported asthma control and asthma-related QOL in patients identified as having suboptimal management of their asthma. A larger trial is needed to confirm the effects are real and sustained.

Chronic disease prevalence and associations in a cohort of Australian men: the Florey Adelaide Male Ageing Study (FAMAS)

Background

An increasing proportion of Australia's chronic disease burden is carried by the ageing male. The aim of this study was to determine the prevalence of asthma, cancer, diabetes, angina and musculoskeletal conditions and their relationship to behavioural and socio-demographic factors in a cohort of Australian men.

Methods

Self-reports of disease status were obtained from baseline clinic visits (August 2002 – July 2003 & July 2004 – May 2005) from 1195 randomly selected men, aged 35–80 years and living in the north-west regions of Adelaide. Initially, relative risks were assessed by regression against selected variables for each outcome. Where age-independent associations were observed with the relevant chronic disease, independent variables were fitted to customized multiadjusted models.

Results

The prevalence of all conditions was moderately higher in comparison to national data for age-matched men. In particular, there was an unusually high rate of men with cancer. Multiadjusted analyses revealed age as a predictor of chronic conditions (type 2 diabetes mellitus, angina, cancer & osteoarthritis). A number of socio-demographic factors, independent of age, were associated with chronic disease, including: low income status (diabetes), separation/divorce (asthma), unemployment (cancer), high waist circumference (diabetes), elevated cholesterol (angina) and a family history of obesity (angina).

Conclusion

Socio-demographic factors interact to determine disease status in this broadly representative group of Australian men. In addition to obesity and a positive personal and family history of disease, men who are socially disadvantaged (low income, unemployed, separated) should be specifically targeted by public health initiatives.
