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

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 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.

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.

The prevalence of asthma and its predictor among patients presetting in Ethiopian public hospitals: systematic review and meta-analysis, 2024

BACKGROUND

Asthma is a leading cause of emergency hospital visits and a significant factor in lost productive hours. The lack of a synthesized body of knowledge on bronchial asthma has notable public health implications.

OBJECTIVE

This systematic review and meta-analysis aim to investigate the prevalence of asthma and its predictors among patients presenting in Ethiopian public hospitals.

DESIGN

Duplicate studies were removed using EndNote version X9. The Newcastle-Ottawa Scale guided the quality assessment, and data extraction followed the Joanna Briggs Institute format.

DATA SOURCE AND METHODS

The authors used advanced search methods, including databases such as PubMed, Scopus, Embase, Africa Index Medicus, Science Direct, HINARI, Google Scholar, and manual searches. Data presentation adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. Publication bias was assessed using Egger's regression test and a funnel plot. Sensitivity analysis was also conducted.

RESULTS

The search yielded 352 original articles, with 22 meeting the criteria for inclusion. Using the random-effects DerSimonian-Laird model, the prevalence of bronchial asthma was found to be 9.02% (95% CI: 7.50, 10.53). Several factors were associated with the prevalence of bronchial asthma, including the spring season (AOR 3.7; 95% CI: 2.11, 6.49), childhood age (AOR 4.2; 95% CI: 1.84, 9.55), and urban residence (AOR 1.7; 95% CI: 1.29, 2.31). Other significant factors include family history of asthma (AOR 2.89; 95% CI: 2.22, 3.75), insecticide exposure (AOR 3.3; 95% CI: 2.23, 4.91), and the presence of household insects like cockroaches (AOR 3.33; 95% CI: 2.15, 5.15). Smoking (AOR 3.64; 95% CI: 2.66, 4.98), obstructive sleep apnea (AOR 4.29; 95% CI: 2.37, 7.76), and recurrent upper respiratory tract infections (AOR 4.31; 95% CI: 2.24, 8.32) were also significant.

CONCLUSION

The pooled prevalence of bronchial asthma is notably high in Ethiopia. Key predictors include childhood age, spring season, urban living, family history of asthma, exposure to insecticides, presence of cockroaches, smoking, obstructive sleep apnea, and recurrent upper respiratory infections. Targeted interventions are crucial and should focus on lifestyle improvements, allergen identification, cockroach control, smoking cessation, reducing insecticide exposure, and promoting a safe environment.

TRIAL REGISTRATION

This review's protocol was pre-registered with the International Prospective Register of Systematic Reviews (PROSPERO registration number CRD42023491222).

Association of quality-of-care indicators with asthma outcomes: A retrospective observational study for asthma care in Singapore

Introduction

Asthma guidelines have advocated for the use of quality-of-care indicators (QCIs) in asthma management. To improve asthma care, it is important to identify effective QCIs that are actionable. This study aimed to evaluate the effect of the presence of 3 QCIs: asthma education, Asthma Control Test (ACT) and spirometry testing on the time to severe exacerbation (TTSE).

Method

Data collected from the SingHealth COPD and Asthma Data Mart (SCDM), including asthma patients managed in 9 SingHealth polyclinics and Singapore General Hospital from January 2015 to December 2020, were analysed. Patients receiving Global Initiative for Asthma (GINA) Steps 3-5 treatment, with at least 1 QCI recorded, and at least 1 severe exacerbation within 1 year before the first QCI record, were included. Data were analysed using multivariate Cox regression and quasi-Poisson regression models.

Results

A total of 3849 patients in the registry fulfilled the criteria. Patients with records of asthma education or ACT assessment have a lower adjusted hazard ratio (HR) for TTSE (adjusted HR=0.88, P=0.023; adjusted HR=0.83, P<0.001). Adjusted HR associated with spirometry is higher (adjusted HR=1.22, P=0.026). No QCI was significantly associated with emergency department (ED)/inpatient visits. Only asthma education and ACT showed a decrease in the number of exacerbations for multivariate analysis (asthma education estimate: -0.181, P<0.001; ACT estimate: -0.169, P<0.001). No QCI was significant for the number of exacerbations associated with ED/inpatient visits.

Conclusion

Our study suggests that the perfor-mance of asthma education and ACT was associated with increased TTSE and decreased number of exacerbations, underscoring the importance of ensuring quality care in clinical practice.
