Determinants of poorly controlled asthma among asthmatic patients in Jimma University Medical Center, Southwest Ethiopia: a case control study

Prevalence and predictors of medication adherence among adolescents and adults with asthma in Ethiopia: a systematic review and meta-analysis

OBJECTIVE

This review aimed to estimate the pooled prevalence and predictors of medication adherence among adolescents and adults with asthma in Ethiopia.

DATA SOURCES

Primary studies were searched from PubMed, Scopus, HINARI, and Google Scholar from January 1, 2010 to December 10, 2023. In addition, we have used citation tracking.

STUDY SELECTIONS

Observational studies (cross sectional, case control, and cohort) conducted among asthmatic patients ≥15 years old in Ethiopia, published in English language were included. After screening, the studies were assessed using Joanna Briggs Institute (JBI) critical appraisal tool and data were extracted using a checklist. Heterogeneity was assessed using forest plot, Q-statistics and I2.

RESULTS

The review was performed among 13 institution-based studies with a total of 2901 participants with asthma. About 1058 participants had comorbid disease and 354 were cigarette smokers. The pooled prevalence of adherence to medications among patients with asthma was 40.50% (95% CI: 28.05, 52.96; p value < 0.001) with high heterogeneity (I2 = 98.25%, p < 0.001). Getting health education about asthma and having comorbid disease were predictors of medication adherence among adolescents and adults with asthma in Ethiopia.

CONCLUSIONS

The pooled prevalence of medication adherence among adolescents and adults with asthma in Ethiopia is low and indicated that three out of five adolescents and adults with asthma were non-adherent to medications. This implies the Ministry of Health should develop different strategies to improve medication adherence including patient education and strengthening the health care system. Multicenter longitudinal studies should be further conducted by using objective methods of adherence measurement and large sample size.

Medication Non-adherence and predictor factors among adult Asthmatic patients in Ethiopia: a Systematic review and Meta-Analysis

Objective: A pronounced burden is evident in individuals with asthma, with approximately half of them not adhering to their prescribed medication. Therefore this study aimed to assess the pooled prevalence of anti-asthma medications non-adherence in Ethiopia.Data sources: A comprehensive search was conducted across multiple electronic databases including PubMed, Africa Index Medicus, Science Direct, Hinari, and a search engine, Google Scholar from October 5 to 20, 2023. In addition, digital research repositories from Addis Ababa and Bahir Dar University were accessed.Data selection: The eligibility criteria was employed to screen studies after uploading search results to EndNote software to remove duplicates first. Then, two investigators, CT and BBT, independently assessed titles, abstracts, and the full text of all retrieved references to identify potentially eligible studies.Result: This meta-analysis, which was conducted in Ethiopia, and included 11 full-text articles, revealed a pooled asthma medication non-adherence level of 51.20% (95% CI, 35.20%, 67.20%) with substantial heterogeneity (I2 = 99.08%). The review has also identified factors predicting non-adherence among asthmatic patients: free (health service) (AOR: 0.31, 95% CI; 0.18-0.54), poor knowledge (AOR: 2.85, 95% CI; 1.61-5.05), absence of formal education (AOR: 3.01, 95% CI; 1.72-5.25), history of Previous ADR(AOR: 8.57, 95% CI; 1.12-65.3), and the presence of Co- morbidity(AOR: 3.28, 95% CI; 2.014-5.68), had shown association with asthma medication non-adherence.Conclusion: Asthma medication non-adherence is notably high in Ethiopia. Addressing medication non-adherence requires a comprehensive approach, including clear communication between healthcare providers, patient education and addressing financial barriers to ensure better adherence in asthma patients.

Prevalence of medication adherence among adult asthmatic patients in four African countries: A systematic review and meta-analysis

Non-adherence to medications has many deleterious effects including poor treatment outcomes, increased economic burden, increased morbidity, hospitalization rate, health care utilization, productivity loss, and mortality. Therefore, this review aimed to estimate the pooled prevalence of medication adherence among asthmatic adults in 4 African countries. Primary studies were extensively searched from databases such as PubMed, HINARI, Cochrane Library, CINHALand, Google Scholar, and Google search engines. After screening and assessing the quality of studies, data were extracted using a checklist. Heterogeneity was assessed using forest plot, Chocran's Q Test and I2. The random effects meta-analysis model was employed to pool the prevalence of medication adherence among adult asthmatic patients in Africa. Sub-group analysis and meta-regression were performed to identify the sources of heterogeneity. Publication bias was assessed using funnel plots with Egger's test. A sensitivity analysis was performed to assess the influence of individual studies on the overall estimate. The review was performed among 16 studies of which 14 were cross-sectional with a total of 4019 participants. The pooled random effects prevalence of adherence to medications among adult patients with asthma in Africa was 39% (95% CI: 32, 47; p < 0.001) with a heterogeneity (I2 = 94.82, p < 0.001). The pooled prevalence of medication adherence among adult asthmatic patients in Africa is low. Researchers should conduct further multicenter longitudinal studies by using objective methods of adherence measurement.

Adherence to anti-asthma medications among adult asthmatic patients in Eastern Ethiopia: A multi-center cross-sectional study

INTRODUCTION

Adherence to anti-asthmatic medications plays a vital role in enhancing an asthma patient's quality of life and prognosis. However, in Ethiopia, the level of adherence and contributing factors were rarely studied. Therefore, this study was conducted to determine the level of adherence to anti-asthma medications and associated factors among adult asthmatic patients in Eastern Ethiopia.

METHOD

Institutional based cross-sectional study was conducted at six governmental hospitals found in Eastern Ethiopia. A total of 320 asthma patients aged 18 years and above and using asthma medicines for at least 12 months were involved. An interviewer based structured questionnaires were used to collect the data. Bivariable and multivariable logistic regression analyses were carried out using IBM SPSS version 22 (SPSS, Chicago, IL). The Adjusted Odds Ratio (AOR) with 95% Confidence Interval (CI) was used to determine the strength of association between independent variables and outcome variable. Variables with a p-value of ≤ 0.05 were considered statistically significant.

RESULT

Of the 320 asthma patients that participated in the study, 109(34.1%:28.8-39.1%) of them had good adherence to anti-asthmatic medications. Being a housewife (AOR = 4.265, 95%CI: 1.333, 13.653), having good knowledge about asthma (AOR = 2.921, 95%CI (1.472, 5.795), positive attitude towards asthma (AOR = 3.129, 95%CI: 1.555, 6.293), and use of oral corticosteroid drugs (AOR = 1.967, 95%CI: 1.008, 3.841) were factors positively associated with good adherence to anti-asthmatic medications. Participants on treatment for 2-3 years (AOR = .295, 95%CI: 0.099, 0.873), and those on medication for ≥ 4 years (AOR = 0.229, 95%CI: 0.079, 0.664) were 70.5% and 77.1% times less likely to adhere to anti-asthmatic medications respectively.

CONCLUSION

The current study signified a low level of adherence to anti-asthmatic medications. Participant's characteristics and medication related factors were significantly associated with good adherence to anti-asthmatic medications. Health education and advice during follow-up for asthma patients is crucial for better adherence.

Variables associated with asthma control among adult patients

Objective: Asthma is one of the most prevalent chronic diseases with a substantial impact on the health status of affected patients. Further research is necessary to identify factors contributing to poor asthma control. The current study aimed to investigate the factors associated with poor asthma control among adult asthmatic patients.Methods: In this case-control study, the Asthma Control Test (ACT) was translated into Arabic and distributed to adults with asthma attending two hospitals in Jordan to evaluate the degree of asthma control. The following variables were collected for each patient: sociodemographic information, comorbidities, appropriate use of inhaler technique, spirometric measurements, and medications use. Binary regression was used to evaluate factors associated with asthma control.Results: A total of 314 participants with a mean age of 51.47 years (±16.37) completed the study. ACT score had a mean of 16.68 (±4.86). The majority of asthmatic patients had insufficiently controlled asthma (64.6%). Binary regression results showed that previous respiratory infection history (p = 0.014, OR = 0.473 (95%CI 0.261-0.857)), higher exposure to irritants (p = 0.010, OR = 0.747 (95%CI 0.598-0.933)) decreased the odds of being in the controlled asthma group. Patients receiving inhaled corticosteroids (ICS) had higher odds of being in the controlled asthma group (p = 0.039, OR = 2.372 (95%CI 1.043-5.392)).Conclusions: The majority of asthma patients had insufficiently managed disease. The main factors that contributed to poor asthma control were respiratory infection history, increased exposure to asthma symptoms triggers, and ICS nonuse.

Factors associated with uncontrolled asthma among adult asthmatic patients in eastern Ethiopia: A multicenter study

OBJECTIVE

Asthma is a major public health problem worldwide. Despite various attempts, it is still uncontrolled in most parts of the world. Moreover, it is contributing to the national and global burden of non-communicable diseases. Studying factors associated with uncontrolled asthma in different parts of Ethiopia is crucial to control the disease and improving the quality of life of asthmatic patients. Thus, this study aimed to determine the factors associated with uncontrolled asthma among adult asthmatic patients in Eastern Ethiopia.

METHODS

Facility-based cross-sectional study was employed from 1st October 2020 to 30th January 2021. A total of 416 adult asthmatic patients participated in the study from six hospitals follow-up clinics. Asthma control test was used to assess the participants level of asthma control and a score of ⩽19 were regarded to have uncontrolled asthma. Data were analyzed using SPSS version 24. Bivariable and multivariable analyses were carried out to identify factors associated with uncontrolled asthma and variables with a p value of less than 0.05 were considered statistically significant.

RESULT

The prevalence of uncontrolled asthma was 66.1 % (95% confidence interval: 61.5-70.4). Not attending scheduled medical follow-up (adjusted odds ratio: 2.54; 95% confidence interval: 1.28-4.99), poor knowledge about asthma (adjusted odds ratio = 4.59; 95% confidence interval: 2.01-10.51), negative attitude toward asthma (adjusted odds ratio = 3.72; 95% confidence interval: 1.83-7.59), and poor adherence to medications (adjusted odds ratio = 2.53; 95% confidence interval: 1.25-5.13) were significantly associated with uncontrolled asthma.

CONCLUSION

In this study, the prevalence of uncontrolled asthma was considerably high. Not attending scheduled medical follow-up, poor knowledge about asthma, negative attitude toward asthma, and poor adherence to anti-asthma medications were associated with uncontrolled asthma. Therefore, it is crucial to focus on increasing the patients' level of awareness about asthma control, improving medication adherence, and avoiding triggering factors.

Asthma control and its predictors in Ethiopia: Systematic review and meta-analysis

BACKGROUND

Determining the status of asthma control and identifying risk factors for poor asthma control is a key strategy for curbing the negative health impacts and the financial burden of the disease. Therefore, this review was aimed to determine the rate of asthma control and assess the predictors of uncontrolled asthma in Ethiopia.

METHODS

PubMed, Web of Science, and Google Scholar searches were performed using key terms; "asthma, bronchial asthma, control, controlled, uncontrolled and Ethiopia" up to October 16, 2020. University repositories were also searched to retrieve gray literature. The results were presented as a prevalence rate with a 95% confidence interval (CI). Subgroup analysis and meta-regression were performed to identify the sources of heterogeneity in the outcomes.

RESULTS

From 1,388 patients, based on the Global Initiative for Asthma (GINA) symptom control, the rate of the uncontrolled asthma was 45.0% (95% CI 34.0% - 56.0%) with a considerable heterogeneity between the studies; (I2: 94.55, p< 0.001). About 19.0% (95% CI 10.0% - 29.0%); (I2: 96.04, p< 0.001) of the asthma patients had a well-controlled asthma. Moreover, 36.0% (95% CI 22.0% - 50.0%), (I2: 97.11, p< 0.001) of patients had a partly controlled asthma. Similarly, based on the asthma control test (ACT), the rate of well-controlled asthma was 22.0% (95% CI 3% - 42.0%), with considerable heterogeneity between the studies; (I2: 97.75, p< 0.001). The most frequent predictors of uncontrolled asthma were incorrect inhalation techniques, frequent SABA use, moderate/severe persistent asthma, history of exacerbations, presence of comorbidities, use of oral corticosteroids, and irregular follow-up.

CONCLUSION

The rate of uncontrolled asthma in Ethiopia was high. Several factors are associated with uncontrolled asthma. Comprehensive asthma educations at each follow-up visit should be strengthened to minimize the morbidity and the cost of uncontrolled asthma.

Practice on Metered Dose Inhaler Techniques and Its Associated Factors among Asthmatic Patients at Debre Markos Comprehensive Specialized Hospital, East Gojjam, Ethiopia: A Prospective Study

Background

Asthma stands 16^th among the leading causes of years lived with disability and 28^th among the leading causes of disease in the world. A metered-dose inhaler remains the principal route for drug administration, and it has greater advantages over systemic treatment. In routine use, however, a majority of patients make inhalation errors. Suboptimal inhaler technique worsens health outcomes, with poor disease control, and increases the risk of hospitalization. This study aimed to assess practice metered-dose inhalation techniques and associated factors among asthmatic patients at Debre Markos Comprehensive Specialized Hospital, East Gojjam, Amhara region, Ethiopia.

Methods

Prospective cross-sectional study was conducted from July 15 to August 30, 2020. Data were collected through a semistructured questionnaire. The data were analyzed using SPSS version 25. Associations between dependent and independent variables were assessed by using binary and multiple logistic regressions. P values less than 0.05 were considered to be statistically significant in all cases. Results are presented in tables, figures, numbers, and percentages.

Result

A total of 166 patients had involved in the study, of which 52.4% were females. One hundred and eleven (66.9%) participants had good knowledge of asthma and inhalational techniques, while the rest of them had poor knowledge. One hundred and eight (65.1%) patients had effective practice on metered-dose inhaler use techniques. Participant's knowledge regarding asthma and meter dose inhaler and marital status has a significant association with their practice of metered-dose inhaler techniques with P value 0.001 and 0.006, respectively.

Conclusion

In this study, most participants are suffering from asthma for a long duration and they have repeated exacerbation. Around two-thirds of patients had good knowledge regarding asthma and metered-dose inhaler and practice on metered-dose inhaler techniques. Participants with poor knowledge had poor practice on metered-dose inhaler techniques, and single patients were less likely to have poor practice on metered-dose inhaler techniques. Health education and counseling services should be consistently provided to the clients regarding the proper steps of inhalers use.

Self-care practice and associated factors among adult asthmatic patients on follow-up care at Northwest Amhara referral hospitals, Northwest Ethiopia 2020

BACKGROUND

Self-care practice of asthma is the strategy for asthma symptom control and future reduction of exacerbation, but it is poorly implemented in clinical settings due to the patients, professionals, and organizational related factors. Therefore, the study aimed to assess the self-care practice and associated factors among adult asthmatic patients at Northwest Amhara referral hospitals.

METHODS

Institution-based cross-sectional study was conducted among asthmatic patients on follow-up care at Northwest Amhara Regional State referral hospitals from February 1st, 2020 to March 30, 2020. Data were collected through an interviewer-administered technique. Asthma self-care practice tool was used to measure the outcome. Data were entered into EPI info version 7 and exported to SPSS version 22 for analysis. A binary logistic regression analysis was used. In multivariable logistic regression analysis, those independent variables having p value < 0.05 were considered as statistically significant with poor self-care practice of asthma.

RESULTS

A total of 470 participants enrolled in the study with a response rate of 100%. The proportion of good self-care practice among asthmatic patients was found to be 42.3%. The study revealed that; age group ≥ 55 years, having a co-morbid illness and borderline anxiety, having no social support, and drinking alcohol were significantly associated with poor asthma self-care practice.

CONCLUSIONS

Poor-self care practice in this study was high. Efforts need to be implemented for asthmatic patients with older age, having co-morbid illness and borderline anxiety, having no social support, and drinking alcohol.

Determinants of uncontrolled asthma among adult asthmatic patients on follow-up at chest clinic of Jimma medical center: unmatched case-control study

OBJECTIVE

To identify the determinants of uncontrolled asthma among asthmatic patients on follow-up at Jimma Medical Center.

METHODS

Institution-based case-control study was conducted on asthmatic patients who were on follow-up at the chest clinic of Jimma University Medical (JMC) from March to May 2020. A total of 59 cases and 118 controls (1: 2 ratio) were included in the study. Cases and controls were defined based on asthma control test (ACT) scores where those who had scores of ≤19 and above 19 were defined to be cases and controls, respectively.

RESULTS

Age of the patients [AOR: 2.78; 95% CI: 1.14, 6.81], age of the cases' residential houses [AOR: 3.65; 95% CI: 1.30, 10.28], presence of pets within the houses [AOR: 2.78; 95% CI: 1.29, 5.96], having rhinitis [AOR: 3.34; 95% CI: 1.17, 9.52], past asthma exacerbation [AOR: 2.38, 95% CI: 1.05, 5.40], non-adherence to treatment [AOR: 2.81; 95% CI: 1.30, 6.08] and smoking [AOR: 7.09; 95% CI: 1.84, 27.33] were found to be determinants of uncontrolled asthma.

CONCLUSIONS

Uncontrolled asthma results from multiple sociodemographic, environmental, clinical, and behavioral factors. Therefore, patients should be counseled on avoiding pets, maintenance of houses, adherence to treatment, quitting smoking, and early treatment-seeking for rhinitis and asthma exacerbation to improve asthma control comprehensively.

Non-adherence to inhaled medications among adult asthmatic patients in Ethiopia: a systematic review and meta-analysis

BACKGROUND

Medication non-adherence is one of a common problem in asthma management and it is the main factor for uncontrolled asthma. It can result in poor asthma control, which leads to decreased quality of life, increase hospital admission, increased health care utilization, lost productivity, and mortality. To date, there have been no studies and protocols that estimated the pooled national prevalence of non-adherence to inhaled anti-asthmatic medications in Ethiopia. Therefore, the primary purpose of this systematic review and meta-analysis is to determine the pooled national prevalence of non-adherence to inhaled medications among asthmatic patients in Ethiopia.

METHODS

Different database searching engines including PubMed, Scopus, Google Scholar, Africa journal online, World Health Organization afro library, and Cochrane review were systematically searched by using keywords such as "prevalence, non-adherence to inhaled medications, inhaled corticosteroids, and asthmatic patients" and their combinations. Six published observational studies that report the prevalence of non-adherence to inhaled medications were finally selected. The Preferred Reporting Items for Systematic Review and Meta-Analysis guideline was followed. Heterogeneity across the included studies was evaluated by the inconsistency index (I2). The random-effect model was fitted to estimate the pooled prevalence of non-adherence to inhale anti-asthmatic medications. All statistical analysis was done using R version 3.5.3 and R Studio version 1.2.5033 software for windows.

RESULTS

The pooled national prevalence of non-adherence to inhaled medications among asthmatic patients was 29.95% (95% CI, 19.1, 40.8%). The result of this meta-analysis using the random-effects model revealed that there is high heterogeneity across the included studies. The result of subgroup analysis indicates that one out of three in the Oromia region and one out of five in the Amhara region asthmatic patients was non-adherent to their inhaled anti-asthmatic medications.

CONCLUSION

the prevalence of non-adherence to inhaled anti-asthmatic medications was high. Thus, our finding suggests that one out of four asthmatic patients were non-adherent to inhaled medications. The ministry of health, health policymakers, clinicians, and other health care providers should pay attention to strengthening the adherence levels to inhaled anti-asthmatic medications, and country-based interventions should be developed to reduce the burden of non-adherence to inhaled anti-asthmatic medications.
