Long-term control medication use and asthma control status among children and adults with asthma

Background: Uncontrolled asthma decreases quality of life and increases health care use. Most people with asthma need daily use of long-term control (LTC) medications for asthma symptoms and to prevent asthma attacks. Ongoing assessment of a person's level of asthma control and medication use is important in determining the effectiveness of current treatment to decrease the frequency and intensity of symptoms and functional limitations. Objective: To assess the use of LTC medication among children and adults with current asthma and identify contributing factors for LTC medication use. Methods: We used the 2006–2010 Behavioral Risk Factor Surveillance System (BRFSS) child and adult Asthma Call-back Survey (ACBS) data to assess the level of asthma control and LTC medication use. Asthma control was classified as well controlled and uncontrolled using guideline-based measures. We used multivariable logistic regression models to identify contributing factors for LTC medication use and having uncontrolled asthma. Results: Among persons with current asthma, 46.0% of children and 41.5% of adults were taking LTC medications and 38.4% of children and 50.0% of adults had uncontrolled asthma. Among children who had uncontrolled asthma (38.4%), 24.1% were taking LTC medications and 14.3% were not taking LTC medications. Among adults who had uncontrolled asthma (50.0%), 26.7% were taking LTC medications and 23.3% were not taking LTC medications. Conclusions: Using BRFSS ACBS data to assess the level of asthma control and LTC medication use can identify subpopulations of persons with asthma who receive suboptimal treatment, for which better asthma-related medical treatment and management are needed.     

Psychological distress,drug use,sexual risks and medication adherence among young HIV-positive Black men who have sex with men: exposure to community violence matters

In the USA, Black males are disproportionately affected by community violence and HIV. The aim of this study was to assess whether exposures to community violence are related to psychological distress, drug use, sexual risk behaviors, and medication adherence among a sample of HIV-positive young Black men who had sex with men (YBMSM). Data are from 98 YBMSM ages 18–29 years recruited from Chicago who completed measures on demographics, exposures to community violence, psychological distress, drug use, condomless anal intercourse, and medication adherence. Rates of exposure to community violence were high and youth reported victimization and witnessing numerous types of violence in their lifetime. In adjusted logistic regression analyses, models indicate that YBMSM reporting higher levels of exposure to community violence had significantly higher rates of condomless anal intercourse in the previous 6 months (AOR: 5.33, 95%CI: 1.38–20.55). Additionally, exposure to community violence was positively associated with psychological distress, hard drug use, and use of marijuana as a sex drug. Adherence to HIV antiretroviral medication was negatively associated with community violence (AOR: 0.36, 95%CI: 0.13–0.97). Rates of exposure to community violence are especially high in urban communities. Overall findings suggest that treatment, intervention, and programmatic approaches that include initiatives to address exposure to community violence might correlate with better health-related outcomes for HIV-positive YBMSM.     

Asthma-like symptoms,diagnostic tests,and asthma medication use in children and adolescents: a population-based nationwide survey

Objective: This study aimed to estimate the prevalence of asthma-like symptoms, current asthma (CA), asthma diagnostic tests, and inhaled medication use in a nationwide pediatric population (<18 years). Methods: Pediatric-specific data from a cross-sectional, population-based telephone survey (INAsma study) in Portugal were analyzed. CA was defined as lifetime asthma and (1) wheezing, (2) waking with breathlessness, or (3) asthma attack in the previous 12 months, and/or (4) taking asthma medication at the time of the interview. Results: In total, 716 children were included. The prevalence of asthma-like symptoms was 39.4% [95% confidence interval (95% CI): 35.7–43.3]. The most common symptoms were waking with cough (30.9%) and wheezing (19.1%). The prevalence of CA was 8.4% (95% CI: 6.6–10.7). Among children with CA, 79.9% and 52.9% reported prior allergy testing and pulmonary function testing (PFT), respectively. Inhaled medication use in the previous 12 months was reported by 67.6% (reliever inhalers, 40.1%; controller inhalers, 41.5%). Those who only used inhaled reliever medications experienced more asthma attacks [odds ratio (OR): 2.69]. Significantly fewer children with CA living in rural areas than those living in urban areas had undergone PFT or used inhaled medication (OR: 0.06 for PFT, 0.20 for medication]. Conclusions: The prevalence of CA in the Portuguese pediatric population was 8.4%. Only half of children with CA had ever undergone PFT; more than half did not use controller inhalers, and those who only used reliever inhalers reported more asthma attacks. These findings suggest that asthma management has been substandard, mainly in rural areas.     

The relationship between Direct to Consumer Advertising (DTCA) and asthma-related emergency department use among Medicaid-enrolled children

Objective: Asthma is a leading cause of emergency department (ED) visits. There has been much debate on the impact of direct to consumer advertising (DTCA) on healthcare. This study seeks to examine the association between DTCA expenditure and asthma-related ED use. Study design: In this study, we combined Medicaid administrative data and a national advertising data on asthma medications. The sample size consisted of 180?584 Medicaid-enrolled children between the ages of 5 and 18 years who had an asthma diagnosis. Twenty percent of the Medicaid-enrolled children in the sample had asthma-related ED visits. Results: We found that DTCA expenditure is associated with a decrease in asthma-related ED visits (OR?=?0.75; CI: 0.64–0.89). However, at higher levels of DTCA expenditure, the likelihood of asthma-related ED visits increases (OR?=?1.25; CI: 1.05–1.49), indicating a decreased relationship between DTCA and asthma-related ED visits. Conclusions: Our findings suggest that DTCA may be associated with improved health outcomes for Medicaid-enrolled children with asthma.     

Perceived benefits and barriers to joint protection among people with rheumatoid arthritis and occupational therapists. A mixed methods study

Background: Deciding whether or not to perform a health behaviour is an active decision‐making process which has an impact on current and future behaviour and can be influenced by the beliefs both of patients and their healthcare professionals. The aim of this study was to explore rheumatoid arthritis (RA) patients' and occupational therapists' (OTs) perceptions of the benefits of and barriers to performing joint protection (JP). Methods: A mixed methods design was used. Questionnaires applied a theoretical framework of key themes to assess the relevance of JP benefits and barriers both to people with RA and OTs. Focused interviews with people with RA then enabled data triangulation. Investigator triangulation was used to check the validity of data interpretation. Findings: Ten people with RA and nine OTs participated. From the questionnaires, both groups agreed that highly relevant key themes for JP benefits were physical well‐being, potential benefit and personal control. By contrast, the three key themes for JP barriers – negative attitude of others, negative impact on others and taking time from other things – were relevant for the majority of the OTs but not patients. The interviews enabled an understanding of the meaning behind RA patients' ratings, particularly their differences from OTs. People with RA explained JP benefits, and disease acceptance had altered some initial barriers into perceived benefits over time. Conclusions: Emphasizing benefits and identifying individually relevant barriers could be an important communication strategy for OTs in understanding patients' rationale for whether or not to adopt JP methods.

Family caregivers' reported nonadherence to the controller medication of asthma in children in Casablanca (Morocco): Extent and associated factors

Objective: Recent statistics show a relatively high prevalence of asthma among Moroccan children and a weak control over their symptoms. To our knowledge, no research has been carried out to document adherence to the controller treatment in this population. This study aims 1) to assess the extent of children's nonadherence to the controller treatment of asthma in an urban region of Morocco as reported by a family caregiver, and 2) to identify the associated factors. Methods: We conducted a cross-sectional study among caregivers of asthmatic children (2–12 years old) in different health and education facilities of Casablanca-Settat. We administered face-to-face questionnaires incorporating validated instruments (Medication Adherence Rating Scale-Asthma (MARS-A), Beliefs about Medicines Questionnaire (BMQ), Asthma Knowledge Questionnaire). Univariate and multivariate log-binomial regressions evaluating the association between several factors and reported nonadherence were performed (prevalence ratios (PR) and 95% confidence intervals (CI)). Results: Through two public hospitals, three private medical clinics, and one private school, 103 caregivers were recruited. Low adherence to the controller treatment of asthma was reported by 48% of the caregivers (MARS-A <45). In the multivariate model, caregivers with the lowest level of knowledge about asthma were almost three times more likely to report low adherence compared to caregivers with the highest level (PR = 2.93; 95% CI: 1.14–7.52). Conclusions: This study highlights the finding that low adherence is widespread in this context and also the importance of targeting caregivers' knowledge of asthma for interventions.     

Impact of patient education on KAP,medication adherence and therapeutic outcomes of metformin versus insulin therapy in patients with gestational diabetes: A Hospital based pilot study in South India

Background and aimThe study assessed the impact of continuous patient education on Knowledge, Attitude, Practice (KAP), medication adherence and extent of glycemic control in pregnant women with gestational diabetes on insulin or metformin therapy.Methods81 women with gestational diabetes (37 on insulin and 44 on metformin) were assessed for KAP using a validated questionnaire and medication adherence using the 8-items Morisky medication adherence scale, fasting, and postprandial blood glucose levels at the baseline and after two education sessions on drug therapy at one and three months intervals. The difference in mean KAP, medication adherence scores, fasting, and postprandial blood glucose levels and the extent of glycemic control with insulin or metformin therapy were assessed statistically.ResultsThere was a highly significant difference in the mean KAP, medication adherence scores, fasting and postprandial blood glucose levels from baseline to follow-up after three months, (P < 0.0001) indicating that continuous patient education had a positive impact on their KAP, medication adherence, blood glucose levels.ConclusionThe study identified that continuous patient education improved their knowledge and practice of medication adherence which reflected on lowered fasting and postprandial blood glucose levels. Glycemic control was found to be the same with metformin and insulin in gestational diabetes.     

Effectiveness of clinical pharmacist-led smartphone application on medication adherence,insulin injection technique and glycemic control for women with gestational diabetes receiving multiple daily insulin injection: A randomized clinical trial

AimTo investigate the efficacy of a clinical pharmacist-led smartphone application (app) on medication adherence, insulin injection technique (IIT) and diabetes-related outcomes among women with gestational diabetes mellitus (GDM) receiving insulin therapy.MethodIn all, 124 women were randomly (1:1 ratio) assigned to receive app intervention plus usual care (intervention) or usual care (control), and were followed up till 12 weeks postpartum. Interventions centralized on medication adherence and IIT. Primary outcome was medication adherence assessed by the 5-item Medication Adherence Report Scale. Secondary outcomes included IIT, insulin requirement, prepartal and puerperal glycemic control, hypoglycemia, and pregnancy and neonatal outcomes.ResultsA total of 119 patients completed the follow-up evaluation (58 intervention, 61 control). Significant more women with high medication adherence in the intervention group was observed (69.0% vs. 34.4%, p = 0.000). The other notable benefits (all p < 0.05) included patient percentage with appropriate IIT, lesser preprandial insulin dose, patient proportion with both qualified prepartal FPG and 2 hPG, and puerperal FPG or HbA1c, fewer hypoglycemia, and lower neonatal intensive care unit (NICU) admission rate. Cesarean delivery rate was higher among intervention cases (p < 0.05). Qualified prepartal glycemic control was related to high medication adherence and proper IIT. NICU admission was associated with complicated with gestational hypertension, deficient medication adherence and premature rupture of fetal membrane.ConclusionCombined with usual care, clinical pharmacist-led smartphone app might be a valid tool for GDM management.     

A qualitative study of parent perspectives on barriers,facilitators and expectations for school asthma care among urban,African-American children

Objectives: Minority children experience the disproportionate burden of asthma and its consequences. Studies suggest ethnic groups may experience asthma differently with varied perceptions and expectations among parents of African-American and Latino children. Because parents coordinate asthma care with the school, where children spend a significant amount of their day, this study’s goal was to determine parents’ perspectives on school asthma management. Methods: Focus groups were conducted with parents of children with asthma at four urban schools whose student population is predominantly African-American. A semi-structured guide was utilized focusing on barriers, facilitators and expectations for asthma care at school. Grounded theory principles were applied in this study. Results: Twenty-two parents (91% females) representing 13 elementary and 10 middle school children with asthma (61% boys) participated in four focus groups. Most children (87%) had persistent asthma. The identified barriers to effective school-based asthma care included limited awareness of children with asthma by teachers/staff, communication issues (e.g. school/parent, within school), inadequate education and lack of management plans or systems in place. In contrast, the identified facilitators included steps that fostered education, communication and awareness, as supported by management plans and parent initiative. Parents described their expectations for increased communication and education about asthma, better systems for identifying children with asthma, and a trained asthma point person for school-based asthma care. Conclusions: Parents of children with asthma identified important barriers, facilitators and expectations that must be considered to advance school asthma management. Improved school-based asthma care could lead to better health and academic outcomes.     

Student perspectives on asthma management in schools: a mixed-methods study examining experiences,facilitators, and barriers to care

Objective: Children spend nearly a third of their day at school, making it a critical point of intervention for those with asthma. This study aimed to illuminate minority students’ experiences with asthma at school and perceptions of facilitators and barriers to care. Methods: A mixed-methods study was conducted with elementary students with asthma. Participants completed a 24-question survey, drawing exercise to depict experiences caring for their asthma at school, and focus group discussion. Drawings were analyzed for narrative and pictorial themes. Discussions were audio-recorded, transcribed, and independently coded for themes. Results: Fifteen children with asthma (8–11?years) participated from two Chicago schools with predominately African-American populations. Most students (79%) indicated they had control of asthma at school, while 85% identified asthma as a problem when exercising. Half (53%) received help with asthma care at school. Drawings depicted cooperative management with adults or peers and the central role of inhalers as part of everyday asthma care in school. Finally, focus groups produced six key themes within the domains of facilitators: 1) support of others, 2) self-efficacy; 3) perception of being normal; and barriers: 4) lack of support from others; 5) difficulty accessing inhaler; 6) perception of being different. Conclusions: This study suggests asthma care plays an important role in students’ school experiences. Stigma around inhaler use, lack of concern by school staff, and limited access to medications remain as barriers to school-based asthma management. Although facilitators, such as support from teachers and peers, do exist, future interventions must address existing barriers.     

It helps me live,sends my children to school,and feeds me: a qualitative study of how food and cash incentives may improve adherence to treatment and care among adults living with HIV in Tanzania

Financial and in-kind incentives have been shown to improve outcomes along the HIV care cascade, however the potential mechanismsthrough which they work remain unclear. To identify the pathways through which incentives improve retention in care and adherence to antiretroviral therapy (ART), we conducted a qualitative study with participants in a trial evaluating conditional food and cash incentives for HIV-positive food insecure adults in Shinyanga, Tanzania. We found that the incentives acted through three pathways to potentially increase retention in care and adherence to ART: (1) addressing competing needs and offsetting opportunity costs associated with clinic attendance, (2) alleviating stress associated with attending clinic and meeting basic needs, and (3) by potentially increasing motivation. Participants did not report any harmful events associated with the incentives, but reported myriad beneficial effects on household welfare. Understanding how incentives are used and how they impact outcomes can improve the design of future interventions.     

Incidence, impact on the family and cost of gastroenteritis among 4 to 6-year-old children in South Australia

BACKGROUND: Gastroenteritis is an important cause of morbidity in both adults and children worldwide. Although the burden of morbidity and mortality is highest in developing countries, gastroenteritis is still a significant cause of morbidity in Australia, particularly in young children. The aims of the present study were to determine the incidence of gastroenteritis among 4-6-year-old children in South Australia, to describe the impact on daily activities of the child and caregiver and estimate the cost of gastroenteritis in this population. METHODS: A diary study of drinking water consumption and gastrointestinal and respiratory symptoms was undertaken among 965 rural children in South Australia over a 6-week period during February-May 1999. Data on the response to gastrointestinal episodes were collected by telephone surveys midway and at the end of the 6-week period. Costing was based on the methods of Hellard et al. RESULTS: The incidence of community gastroenteritis among 4-6-year-old children was 5.53 episodes per child-year (95% confidence interval: 4.87-5.80). The costs associated with childhood gastroenteritis were estimated to be between 16,858,360 AU dollars and 22,477,814 AU dollars per annum. CONCLUSIONS: The incidence of community gastroenteritis among the 4-6-year-olds in the South Australian population is high and it costs the community a significant amount of money in terms of direct medical costs and time lost by parents and carers looking after their ill children.     

Evaluation of inhaler technique,adherence to therapy and their effect on disease control among children with asthma using metered dose or dry powder inhalers

Objective: To address the problems about correct use of inhaler devices, adherence to inhaler corticosteroid treatment and the effects of these problems on the control of asthma. Methods: Children with asthma were evaluated for the correct use of inhaler devices and adherence to therapy using a questionnaire. Effect of these on control of asthma was defined. Results: A hundred and seventy-one patients and/or their families were interviewed. The mean age was 8.29?±?4.65 years (1–19) and 62.6% were male. Metered dose inhaler (MDI) with spacer was used by 119 (69.5%) patients and 52 (30.5%) used dry powder inhalers (DPIs). The devices were used correctly by 68.1% of patients using MDI and 34.6% of patients using DPI (p?<?0.001). The most common improper step was “breathe in from the spacer 5–6 times or 10?s” for MDI (24.4%) and “exhale to residual volume” for DPI (51.9%). Frequency of correct use was higher in patients trained 3 times (p?<?0.001). Asthma was controlled more frequently among correct users (p?<?0.001). Partial or poor adherence was showed 22.8% of patients. Patients with mothers who had lower educational status had higher frequency of incorrect use of inhaler device (p?=?0.007). Conclusion: It was found that asthma control was better among correct users. Repetitive training about using devices may contribute improving inhaler technique. Especially children whose mothers had low education level and patients using DPI should be evaluated more carefully.
