Concerns of patients with allergic rhinitis: the Allergic Rhinitis Care Programme in South Africa.

BACKGROUND: The major reason for treating chronic rhinitis is to improve quality of life. Although primary symptoms cause morbidity in their own right, these symptoms are significantly aggravated by the impact of cognitive dysfunction and quality of life. OBJECTIVE: The Allergic Rhinitis Care Programme was initiated by the South African Allergic Rhinitis Working Group. An important task of this programme was to document health-related quality of life impairment amongst allergic rhinitis patients in South Africa. METHODS: A questionnaire, appropriate to South Africa, was distributed to patients. The questionnaire inquired about symptoms, quality of life, complications, trigger factors, associated allergic conditions, medication preference, medication adherence and concerns about the condition. RESULTS: 1181 people completed the questionnaire and returned the survey. Nasal congestion was identified as a common and frequent problem, while seasonality of symptoms was uncommon. Symptoms affected sleep in 76.6% of sufferers, and in at least a third this was every night. Over 1000 respondents felt miserable due to allergic rhinitis (85.2%). 63.1% indicated that they always followed instructions for taking rhinitis medication. A variety of perceived concerns around having and being treated for allergic rhinitis were identified, suggesting multiple reasons for non-adherence. CONCLUSIONS: We report symptom frequency and quality of life impairment for respondents who identify themselves as having allergic rhinitis. Since allergic rhinitis is, in the main, a doctor-diagnosed condition, this would suggest a significant problem with inappropriate, insufficient or incorrect therapy.     

Quality of life and economic features in elderly asthmatics

BACKGROUND: In the geriatric population, asthma tends to be overlooked. Moreover, typical symptoms of asthma may mimic chronic bronchitis and emphysema. OBJECTIVE: To compare the characteristics of asthma between elderly (>/=65 years) and adult (<65 years) asthma patients with regard to asthma severity, health-related quality of life, and direct expenditures for medical care generated by the disease. METHODS: A cross-sectional study was made in the asthmatic population older than 14 years in the area of Barcelona, Spain. Asthma severity was determined according to the International Consensus criteria of 1992. St. George's Respiratory Questionnaire (SGRQ) was used to measure the quality of life. Direct costs were calculated registering all costs generated by each patient per year. RESULTS: The study population consisted of 282 adult asthmatics and 51 elderly asthmatics. Asthma was more severe in the elderly group (mild 10%, moderate 35%, severe 55%) than in the adult group (mild 47%, moderate 35%, severe 18%). Elderly asthmatics had significantly higher total SGRQ scores (48 vs. 35, p < 0.001) than adult asthmatics, as well as significantly higher scores for all subscales. Asthma-derived direct costs in elderly asthmatics (mean USD 1,490 vs. USD 773) were double those in adult asthmatics, mainly due to higher costs of hospitalization and medication in the elderly. CONCLUSIONS: Asthma in elderly people as compared with asthma in adulthood was more severe and was associated with a worse health-related quality of life, and significantly higher expenditures for medical care.     

The patient's perspective: adherence or non-adherence to asthma controller therapy?

STUDY OBJECTIVE: Adherence with controller therapy poses a major challenge to the effective management of persistent asthma. The aim of this study was to explore the patient-related aspects of adherence among adult asthmatics. DESIGN AND PARTICIPANTS: The participants (n = 509 adult asthmatics), recruited from all parts of Denmark, answered the questionnaire concerning asthma knowledge, attitudes, adherence, and treatment through the Internet. RESULTS: A total of 67% of the patients were prescribed inhaled corticosteroids (ICS). However, according to Global Initiative for Asthma (GINA)-guidelines' symptom severity classification, 85% should have been on ICS. Accidental and intentional non-adherence with ICS at least twice a week was reported by 27% and 24%, respectively. In case of deterioration, 60% of the patients preferred to take more reliever medication, instead of increasing the ICS dose. Having a fixed daily routine with regard to medication and following the advice given by their doctor were the main reasons for adherence, whereas lack of perceived symptoms was the main reason for non-adherence. Non-adherence was associated with increasing disagreement with the statements that controller therapy is effective (p < 0.04), as well as an essential part of asthma therapy (p < 0.002). CONCLUSIONS: Both accidental and intentional non-adherence with controller therapy is common among adult asthmatics. The reasons for suboptimal adherence seem to be accessible through education of both patients and caregivers.     

Relationship between guideline treatment and health-related quality of life in asthma.

The aim of this study was to compare the health-related quality of life (HRQL) of asthma patients treated according to the 1997 National Institute of Health (NIH) international asthma guideline and that of asthmatics receiving non-guideline treatment. The suitability of 146 asthmatics' medication regimes was determined according to the 1997 NIH asthma guideline. Quality of life was assessed on a seven-point scale using the Asthma Quality of Life questionnaire. Just over half of the patients were not currently using the treatment considered necessary for controlling their asthma. Patients treated according to the guideline (n=72) had a significantly higher overall HRQL than patients with non-guideline treatment (5.7 versus 5.3). The differences were also significant for the subscales measuring symptoms and environmental exposure, but not for activities or emotional function. An association between non-guideline treatment and a poorer health-related quality of life in asthma patients treated in general practice was observed. This study supports the role of evidence-based guidelines in daily practice. Further studies are needed to determine if guideline treatment is responsible for the increase in health-related quality of life observed in this work.     

Respira project: Humanistic and economic burden of asthma in Brazil

Objective: To determine the association of asthma on health-related quality of life (QoL), productivity, and use of healthcare resources among adults in Brazil. Methods: Data were analyzed from the 2015 Brazil National Health and Wellness Survey, a cross-sectional survey with 12,000 adult respondents. Asthma and control groups were compared with respect to health-related QoL, asthma control, work productivity, and adherence. Generalized linear models were developed to compare asthma-related associations controlling for potential confounding factors. Results: Among respondents, 4.1% (n = 494) reported an asthma diagnosis; those without asthma symptoms were used as the control group (n = 11,487). Regarding asthma control, 51.2% of patients had uncontrolled asthma, 36.4% partially controlled asthma, and 12.3% were fully controlled. Short-acting β2 agonists were the most commonly used class of drugs (38.5%). Approximately 32.4% of asthma patients were considered fully adherent to their treatment. In multivariable analyses, asthma patients presented lower health-related QoL and had more frequent visits with medical healthcare providers (6.1 versus 4.2) emergency room visits (1.0 versus 0.5), and more hospitalizations (0.4 versus 0.2), than control respondents six months prior to the study (p < 0.05). Rates of absenteeism and presenteeism varied between 11.5% and 7.4% (p < 0.05) and 30.4% and 20.9% (p < 0.001) between asthma patients and controls, respectively. Conclusions: Asthma had a negative association on health-related QoL, work productivity, and use of healthcare resources. Excessive use of short-acting β2 agonists and poor treatment adherence reflect poor asthma control and suggest the need to implement new strategies for asthma treatment in Brazil.     

Combining pharmacy expertise with asthma educator certification: assessing the impact on inner-city asthma patients

Objective: Asthma is one of the major causes of hospital readmissions in the South Bronx. The goal of this study was to assess the impact of asthma education provided by registered pharmacists with asthma educator certification (AE-C), on medication adherence and hospitalizations/Emergency Department (ED) visits. Methods: This was a retrospective chart review of patients seen in the pulmonary clinic from October 2014 to August 2015 for asthma education by AE-C pharmacists. Medical records were reviewed over an 18-month period – 9?months before and after the initial asthma education session. Data obtained included adherence to asthma controller inhalers based on pharmacy refill claims, asthma control using asthma control test (ACT) scores and asthma-related hospitalizations or ED visits within 30?days of asthma education. Pre-education data served as the pre-intervention group data and post-education data served as the post-intervention group data, allowing each patient to serve as their own control. Results: We found a statistically significant improvement in average medication adherence, i.e. asthma controller inhaler fills at pharmacy (46.3% vs 67.9%, p-value <0.001) and asthma control (15.71% vs 56.38%, p-value <0.001) between the pre-intervention and the post-intervention groups. Additionally, a lower hospitalization/ED utilization rate (31.2% vs 6.38%, p-value <0.001) was observed in the post-intervention group within 30?days of education. Conclusions: Asthma education provided by AE-C pharmacists had a positive impact on asthma care in our inner-city community. Improving medication adherence and asthma control as well as decreasing hospital utilization could potentially decrease health care costs in addition to improving quality of life.     

The Patient's Perspective: Adherence or Non-adherence to Asthma Controller Therapy?

Study objective. Adherence with controller therapy poses a major challenge to the effective management of persistent asthma. The aim of this study was to explore the patient-related aspects of adherence among adult asthmatics. Design and participants. The participants (n = 509 adult asthmatics), recruited from all parts of Denmark, answered the questionnaire concerning asthma knowledge, attitudes, adherence, and treatment through the Internet. Results. A total of 67% of the patients were prescribed inhaled corticosteroids (ICS). However, according to Global Initiative for Asthma (GINA)-guidelines' symptom severity classification, 85% should have been on ICS. Accidental and intentional non-adherence with ICS at least twice a week was reported by 27% and 24%, respectively. In case of deterioration, 60% of the patients preferred to take more reliever medication, instead of increasing the ICS dose. Having a fixed daily routine with regard to medication and following the advice given by their doctor were the main reasons for adherence, whereas lack of perceived symptoms was the main reason for non-adherence. Non-adherence was associated with increasing disagreement with the statements that controller therapy is effective (p < 0.04), as well as an essential part of asthma therapy (p < 0.002). Conclusions. Both accidental and intentional non-adherence with controller therapy is common among adult asthmatics. The reasons for suboptimal adherence seem to be accessible through education of both patients and caregivers.     

Risk behaviors and health-related quality of life among adults with asthma: the role of mental health status

BACKGROUND: Previous research indicates that asthma is strongly associated with depressive disorders. Depression among persons with asthma is associated with poor adherence to medication regimens, more severe asthma, and poorer disease outcomes. The objective of our study was to examine the association of frequent mental distress (FMD) [ie, > or = 14 days in the past 30 days in which respondents reported that their mental health was not good] with modifiable risk behaviors (ie, smoking, physical inactivity, and obesity) and health-related quality of life among adults with asthma. METHODS: The Behavioral Risk Factor Surveillance System is an ongoing, state-based survey that is conducted by random-digit dialing of noninstitutionalized US adults aged > or = 18 years. In 2001, all 50 states administered the asthma and risk behavior questionnaires (15,080 questionnaires). A total of 12 states administered the health-related quality-of-life questionnaire (3,226 questionnaires). We estimated prevalences, 95% confidence intervals, odds ratios, and adjusted odds ratios (AORs) using a statistical software program to account for the complex survey design. RESULTS: The prevalence of FMD among adults with asthma was 18.8%. After adjusting for sociodemographic characteristics, the overall associations between smoking and FMD (AOR, 1.9), and between physical inactivity and FMD (AOR, 1.7) were statistically significant. In addition, among those with asthma, persons with FMD were significantly more likely than those without FMD to report fair/poor general health, frequent physical distress, frequent activity limitations, frequent anxiety, and frequent sleeplessness. CONCLUSIONS: FMD is highly prevalent among persons with asthma, suggesting an apparent synergistic effect of these two conditions. The assessment of the mental health status of persons with asthma by health-care providers appears to be warranted and may prevent the emergence of risk behaviors yielding deleterious effects on the management of this disease.     

Prevalence,Demographics, and Health Outcomes of Comorbid Asthma and Overweight in Urban Children

Background. Asthma and overweight are epidemic in urban children but the relationship between these conditions is not fully understood. This study presents demographic and risk profiles of comorbidity for overweight asthmatic children, characterizes morbidity by comparing health outcomes among overweight asthmatics and healthy weight asthmatics, and examines socioeconomic factors associated with comorbidity. Objective. To construct a demographic profile of overweight asthmatic children in an urban setting and identify factors that contribute to prevalence. Method. Cross-sectional study of 5250 children in New York City public elementary schools using a parent-report questionnaire on body mass index, socioeconomic status, asthma, and asthma-related outcomes. Results. Prevalence of overweight (body mass index ≥ 85th percentile for age and gender) was 50.9%. The prevalence of overweight and ever being diagnosed with asthma was 10.9%. The prevalence of overweight with current asthma was 6.2%. Overweight current asthmatics had more night symptoms, missed school days, and asthma medication use than healthy weight asthmatics. Almost 50% of overweight current asthmatic children reported emergency department visits for asthma compared with 30% of healthy weight asthmatics. Comorbidity was most prevalent among males, Latinos, and children in low-income households, with the highest prevalence among Puerto Ricans. In multivariate analysis stratified by gender, the most significant factors associated with comorbidity among girls were low income and minority race/ethnicity, while among boys significant factors were parental education and parental history of asthma. Interestingly, there were few underweight children (7.8%) but they had high prevalence of asthma (13.8%). Conclusions. The comorbidity of overweight and asthma has a large impact on urban populations, causing greater disease burden than asthma alone. Overweight asthmatics show more uncontrolled asthma, evidenced by emergency department visits, quick-relief medication use, and days with asthma symptoms. The relationship between socioeconomic factors and the asthma–obesity comorbidity may vary by gender and requires further study to identify successful interventions to reduce disease in children.     

Asthma Beliefs Are Associated with Medication Adherence in Older Asthmatics

BACKGROUND

Empirical research and health policies on asthma have focused on children and young adults, even though asthma morbidity and mortality are higher among older asthmatics.

OBJECTIVE

To explore the relationship of asthma-related beliefs and self-reported controller medication adherence in older asthmatics.

DESIGN

An observational study of asthma beliefs and self-management among older adults.

PARTICIPANTS

Asthmatics ages ≥60 years (N = 324, mean age 67.4 ± 6.8, 28 % white, 32 % black, 30 % Hispanic) were recruited from primary care practices in New York City and Chicago.

MAIN MEASURES

Self-reported controller medication adherence was assessed using the Medication Adherence Report Scale. Based on the Common Sense Model of Self-Regulation, patients were asked if they believe they only have asthma with symptoms, their physician can cure their asthma, and if their asthma will persist. Beliefs on the benefit, necessity and concerns of treatment use were also assessed. Multivariate logistic regression was used to examine the association of beliefs with self-reported medication adherence.

KEY RESULTS

The majority (57.0 %) of patients reported poor adherence. Poor self-reported adherence was more common among those with erroneous beliefs about asthma illness and treatments, including the “no symptoms, no asthma” belief (58.7 % vs. 31.7 %, respectively, p < 0.001), “will not always have asthma” belief (34.8 % vs. 12.5 %, p < 0.001), and the “MD can cure asthma” belief (21.7 % vs. 9.6 %, p = 0.01). Adjusting for illness beliefs, treatment beliefs and demographics, patients with a “no symptoms, no asthma” belief had lower odds of having good self-reported adherence (odds ratio [OR] 0.45, 95 % confidence interval [CI] 0.23-0.86), as did those with negative beliefs about the benefits (OR 0.73, 95 % CI 0.57-0.94) and necessity (OR 0.89, 95 % CI 0.83-0.96) of treatment.

CONCLUSIONS

Illness and treatment beliefs have a strong influence on self-reported medication adherence in older asthmatics. Interventions to improve medication adherence in older asthmatics by modifying illness and treatment beliefs warrant study.

Seasonal changes influence the improvement in asthma symptoms by exercise training in subjects with asthma**

Objective: To investigate whether patients with moderate-to-severe asthma who commence an exercise training program in winter or summer show differences in exercise capacity, health-related quality of life (HRQoL) and asthma symptoms. Methods: Forty-two consecutive subjects visiting the outpatient clinic were enrolled in the 17-week rehabilitation program. One group of patients received the intervention from summer to winter (SWG, n?=?21), and the other group participated from winter to summer (WSG, n?=?21). Before and after the exercise training program, all patients were evaluated by cardiopulmonary exercise test, pulmonary function test, quality of life questionnaire and a daily diary that evaluated clinical asthma symptoms. Results: After the training period, both groups improved similarly in health-related quality of life (HRQoL) and aerobic capacity. The WSG patients had a greater increase that those in the SWG in asthma symptom-free days (p?<?0.05). Conclusions: Our results indicate that seasonal variations affect the improvement in asthma symptoms after an exercise training program but have no effect on health-related quality of life, exercise capacity or pulmonary function.     

Assessing health outcomes,quality of life,and healthcare use among school-age children with asthma

Objective: Asthma affects six million children in the United States. Most people can control their asthma symptoms with effective care, management, and appropriate medical treatment. Information on the relationship between asthma control and quality of life indicators and health care use among school-age children is limited. Methods: Using the 2006–2010 combined Behavior Risk Factor Surveillance System Asthma Call-back Survey child data, we examined asthma control and asthma attack status among school-age (aged 5–17 years) children with asthma from 35 states and the District of Columbia. Multivariable logistic regression models were used to assess if having uncontrolled asthma and having ≥1 asthma attacks affect quality of life (activity limitation and missed school days) and healthcare use (emergency department [ED] visits and hospitalizations). Results: About one-third (36.5%) of the 8,484 respondents with current asthma had uncontrolled asthma and 56.8% reported ≥1 asthma attack in the past year. Having uncontrolled asthma and having ≥1 asthma attack were significantly associated with activity limitation (aPR = 1.43 and 1.74, respectively), missed school (1.45 and 1.68), ED visits (2.05 and 4.78), and hospitalizations (2.38 and 3.64). Long-term control (LTC) medication use was higher among respondents with uncontrolled asthma (61.3%) than respondents with well-controlled asthma (33.5%). Conclusions: Having uncontrolled asthma is associated with reduced quality of life and increased health care use. However, only 61.3% of respondents with uncontrolled asthma use LTC medications. Increasing use of LTC medications among children with uncontrolled asthma could help improve quality of life and reduce health care use.     

Quality of Life in Young Urban Children: Does Asthma Make a Difference?

The purpose of this study was to determine whether asthma status and severity have an impact on the quality of life of urban elementary school children. Participants were 1292 caregiver-child dyads from six schools serving low-income, ethnic minority, urban families; 53% of the children were female. Caregivers provided data on the children's asthma diagnosis and frequency in the last 12 months of asthma symptoms, use of medication for asthma, emergency room visits, and hospitalizations. Using the KINDL, a generic quality of life instrument, children reported on their health-related quality of life (HRQL). Results revealed a high prevalence of current asthma (18%). No differences were found in HRQL based on having current asthma or the severity of asthma as assessed by proxy measures of health care utilization and limited functioning. These findings are consistent with previous research indicating that HRQL is influenced by several factors other than asthma status and severity. The implications of these results for intervention are discussed.     

Assessing adherence and factors associated with adherence in young children with asthma

Background and objective:   Adherence with preventive asthma medication by young children is an important factor when evaluating a suboptimal response to treatment. However, few data exist regarding the accuracy of subjective measures of adherence and factors associated with adherence in young children.
Methods:   Fifty-one asthmatic children aged 18 months to 7 years had their use of preventive asthma medication monitored using an electronic monitoring device (Smartinhaler) for 1 month. At a follow-up visit the child's parent was asked how often medication had been given and they also completed a confidential questionnaire that included questions about medication usage, barriers to optimal adherence and parenting. The treating physician made an estimate of the child's likely use of medication.
Results:   The median use of medication as determined by the Smartinhaler was 70.5% (range 21.4–100%). The parents' verbal reports (85.1%) and questionnaire responses (84.2%) overestimated medication usage. The physician was not able to determine which parents correctly estimated their child's use of medication ( P  = 0.28). The child's age, level of parental education and annual family income did not influence adherence. Parents reported simply 'forgetting' or their child's 'reaction to being given medication' as the principal barriers to adherence. There was a significant association between how stressful the parent found parenting and adherence ( P  = 0.05).
Conclusion:   Adherence with preventive medication, even within the context of a research study, was generally low and highly variable. Subjective measures of adherence were found to overestimate adherence in young asthmatics.     

Health-related quality of life in a sample of HIV-infected South Africans

The study aims to assess the health-related quality of life and HIV symptoms of a sample of people living with HIV (PLHIV) in South Africa. The sample included 607 PLHIV from all districts of the Eastern Cape Province, recruited either through a health facility, from the community through key informants, or through support groups. At the time of the study, 66% of the respondents reported having been given an AIDS diagnosis (advanced stage of HIV disease), 48% were on antiretroviral therapy (ART), and 35% were receiving a disability grant. The findings indicate a low degree of overall quality of life, with a mean score of 13.4 on the WHOQOL-HIV measure. Among the WHOQOL-HIV BREF subscales, logistic regression identified spirituality, environment, psychological health, and level of independence as predictors for overall quality of life. Among medical variables and HIV symptoms, CD4 cell count and having fewer HIV symptoms but not an AIDS diagnosis were identified as predictors for overall quality of life; among socio-economic variables, having sufficient food and a higher educational level were identified as predictors. The results highlight the need for better access to psychosocial support and medical services for PLHIV in South Africa, as well as the need to consider a patient's general health perceptions during the course of ART.     

Quality of life in young urban children: does asthma make a difference?

Quality of life in asthma: a comparison of community and hospital asthma patients.

This study compares the quality of life of a community sample of people with asthma in South Australia, using population norms, people suffering from other chronic diseases, and a sample of asthma patients from two hospital clinics. A representative population survey was performed by trained interviewers in spring 1995 of 3001 respondents aged > or = 15 years. A physician's diagnosis of current asthma was reported by 299 (9.9%). The hospital clinic sample had a physician's diagnosis and lung function evidence of asthma (n = 293). All completed the SF-36 health survey. Standardized SF-36 scores, adjusted for age, sex, and social class, were significantly lower for respondents with asthma, compared with population norms, across all subscales of the SF-36 (p < 0.05). Physical component summary (PCS) and mental component summary (MCS) scores were not significantly different in people in the community sample with asthma from scores in people with diabetes and arthritis. PCS and MCS scores did not differ for those with similar symptom frequency in the community and hospital asthma samples, except that hospital patients with frequent symptoms had significantly lower MCS scores (p < 0.01). Asthma has a major impact on the health-related quality of life in the community, comparable to other chronic diseases. The SF-36 performs uniformly in asthma in different situations.     

Depressive symptomatology,quality of life and disease control among individuals with well-characterized severe asthma

Abstract

Objectives: A thorough examination of the relationship of asthma severity and control with symptoms of depression is needed to identify groups of asthmatics at high risk for poor disease control outcomes. This study examines the relationship of symptoms of depression with severity and control in a well-characterized cohort of asthmatics and healthy controls. Methods: Depressive symptoms and quality of life were assessed using the Beck Depression Inventory. Disease control was measured by a composite index incorporating symptoms, activity limitation and rescue medication use. Results: Individuals with asthma (n?=?91) reported more symptoms of depression than controls (n?=?36; p?<?0.001). Those with severe asthma (n?=?49) reported more symptoms of depression (p?=?0.002) and poorer asthma control (p?<?0.0001) than those with not severe asthma. Worse asthma control was associated with more depressive symptoms in severe (r?=?0.46, p?=?0.002) but not in not severe (r?=?0.13, p?=?0.40) asthmatics. The relationship of symptoms of depression among severe asthmatics was attenuated by disease control. Exploratory analyses identified specific disease symptom characteristics, as opposed to exacerbations, as associated with symptoms of depression. Conclusions: Among individuals with severe asthma, increased symptom burden is positively associated with risk for co-morbid depression. These findings point to a need for regular mood disorder screenings and treatment referrals among this group. Further research is warranted to examine whether treatment of comorbid depression improves treatment adherence and asthma-related quality of life.
