The rate of medication nonadherence and influencing factors: A systematic Review

et al. 2023

Lack of adherence to recommended therapy will reduce its effectiveness and can subsequently lead to disease progression, disabilities or even death. A vast number of research studies have emphasized the magnitude of medication nonadherence and its effect on treatment outcomes, patient’s health, healthcare providers and the associated costs; medication nonadherence remains a major concern that is believed to be widely practiced amongst medication taking patients. The current systemic review aims to cohere the available evidence regarding medication nonadherence rate, practices, and potential affecting factors and predictors. A search through different databases was conducted, including PubMed, Medline, and CINHAL for recently published research articles, within five years. The terms used for the search include medication nonadherence, medication nonadherence, factors affecting medication nonadherence and predictors of medication nonadherence. The search was limited to human subjects, English language journal articles and exclusion of review articles, case studies, and data from clinical trials as patient adherence is closely observed.<br /> The search resulted in 667 articles and only 65 articles were included and further screened. However, according to our exclusion criteria, 15 articles only were included in this review. The three most reported practices of medication nonadherence are prescription abandonment, nonconforming, and non-persistence. There are five reported factors that may lead to nonadherence practices such as socioeconomic-related factors, healthcare system-related factors, patient-related factors, disease-related factors, and therapy-related factors. In conclusion, medication nonadherence practice is a multi-dimensional phenomenon that requires a multi-targeted solution.

“…Participants on oral corticosteroid types of medications have better adherence than those on other types of drugs. In contrast, studies conducted in Cameroon and Ethiopia outlined no association between the types of drugs used and the level of adherence to anti-asthmatic medications [ 38 , 39 ]. This discrepancy could be related to the difference in the categories of medications taken by participants, with the current study including seven types of medications while the previously conducted studies included only three categories of anti-asthmatic medications.…”

“…In the current study, receiving anti-asthmatic medications for a longer period of time was found to be associated with poor medication adherence. According to the study conducted in Cameroon, there was no association between the duration of asthma treatment and adherence to anti-asthmatic medications [ 38 ]. This may be related to the fatigue that occurs after taking drugs for an extended period of time [ 12 ].…”

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

et al. 2022

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.

“…The role of the pharmacist in asthma management is growing with time (Benavides, Rodriguez & Maniscalco-Feichtl, 2009). The visits of asthma patients to healthcare providers are also necessary to keep the disease under control and show adherence to therapy (Ngahane et al, 2016), which can be improved through shared decision-making strategies between patients and pharmacists in chronic conditions (Wilson et al, 2010).…”

Efficacy of an education session by pharmacists for patients with asthma: A randomised controlled trial

et al. 2022

Background: Asthma education interventions are provided by pharmacists in many developed countries, although it is still a matter of concern in developing countries. This study aimed to evaluate the effectiveness of pharmacist education sessions on asthma patients. Methods: A three-month single-blinded randomised control trial was conducted to evaluate the impact of pharmacist education sessions on asthma patients. The 60-minute pharmacist sessions provided education to patients about asthma management. The primary outcome of the study was to measure the change in the score of the asthma control questionnaire (ACQ). Results: The 82 participants who completed the study were grouped into two groups. A clinically significant improvement of p>0.5 in the ACQ score was found in the symptoms and environment domains in the intervention group. A significant difference in the ACQ score was also found between the two groups (p=<0.05) after 1 and 2 months of intervention. The proportion of patients with controlled asthma increased from 26 (63.4%) to 31 (75.6%) after the second follow-up in the intervention group. Furthermore, a significant increase (p=0.043) in the AQLQ score was noticed from 4.834 at baseline to 5.433 after the intervention. Conclusion: This study concluded that short-time pharmacist education sessions could improve patients asthma status and quality of life.
