Assessment of medication adherence, medication safety awareness and medication practice among patients with lung cancer: A multicentre cross-sectional study

A Cross-Sectional Evaluation of Knowledge of Medicine Safety and Frequency of Reading Medication Leaflets and Its Predictors - Insights from Saudi Adults in Riyadh, Saudi Arabia

Background and Aim

On the other hand, patient safety, is of the utmost importance, in addition to health care providers' counseling and advice, patient information leaflets (PILs) also have a significant impact on health outcomes. This study aimed to assess the Knowledge of medicine safety and Frequency of reading medication Leaflets and their predictors among the Saudi population in Riyadh Saudi Arabia.

Methods and Materials

This cross-sectional study was conducted over three months in 2023 using online structured self-administered questionnaires, on the adults of Saudi Arabia, admitted to provide informed consent, aged ≥18 years, able to complete the questionnaires, being Saudi nationals, and currently living in the country. The data analysis was performed using the Statistical Package for Social Science (SPSS) version 27.

Results

In this study, 23.6% (n=123) of respondents always read the PILs, while 14.6% (n=76) of them never read the PILs. In addition, 22.6% (n=118) of them find it difficult to understand the PILs. In this study, 53.9% of them revealed that ADRs are unexpected reactions after taking the normal dose and 15.4% of them do not know what ADRs are. The respondents gender (B= 0.164; SE=0.075; 95CI = 0.017-0.310; p = 0.029), Social status (B = 0.251; SE = 0.079; 95CI = 0.096-0.406; p = 0.002) and monthly income (B= 0.136; SE = 0.021; 95CI = 0.095-0.178; p < 0.001) was the predictor of reading PILs.

Conclusion

In this study, two-thirds of participants took medication and knew why they were taking it. However, only a few of them took the medicine after seeing a doctor, suggesting self-medication practice. In addition, 22.1% of them find it difficult to understand the PILS, and a small number of them would rather read it. Highlighting the significance of seeking medical advice from healthcare professionals before using a medication.

Medication Adherence in Cancer Patients: A Comprehensive Review

Cancer is a complex disease that can affect different parts of the body. The rates of cancer have shown an increasing trend in the past decade. A majority of cancers are detected late, therefore becoming untreatable and resulting in significant mortality. Additionally, the lack of awareness about cancers, their risk factors, diagnostic modalities, and preventive measures contributes to increased burden among people. Despite significant developments in the therapeutic and comprehensive management of cancers, the cause for concern is the lack of medication adherence. This is majorly attributed to the adverse effects of the medication, the cost of the drugs, and other reasons. This review comprehensively discusses various aspects of cancer medication adherence that include therapeutic modalities for treating cancers, factors influencing medication adherence, barriers, and facilitators to medication adherence.

Safety analysis of antineoplastic drugs for lung cancer: a retrospective analysis based on Shaanxi Province in Western China

BACKGROUND

China has the highest proportion of lung cancer-related deaths. Drug therapy is the main tool of comprehensive anticancer treatment. However, most studies to date have focused on certain types of targets or immunotherapeutic modalities for drug safety; few studies have addressed the factors that influence ADRs for each type of drug in patients with lung cancer, and even fewer studies have explored the risk factors for certain types of ADRs. Based on it, we comprehensively evaluate the drug safety of patients and provide a clinical reference with a focus on lung cancer.

RESEARCH DESIGN AND METHODS

We examined 767 reports of adverse drug reactions (ADRs) in patients with lung cancer and conducted a logistic regression analysis on the risk factors that may cause different types of organ system damage and serious ADRs.

RESULTS

The logistic regression identified various independent risk factors for system organ damage, and ADRs involving erythrocyte abnormalities (P < 0.001), respiratory system damage (P < 0.001), and leukocyte and reticuloendothelial system abnormalities (P < 0.001) were more likely to be severe.

CONCLUSIONS

Rare adverse reactions and different Clinical medication guidelines for molecular-targeted drugs were identified. These findings had certain practical significance in clinical safe drug use.

Use of Failure Mode and Effects Analysis (FMEA) for Risk Analysis of Drug Use in Patients with Lung Cancer

It is crucial to investigate the risk factors inherent in the medication process for cancer patients since improper antineoplastic drug use frequently has serious consequences. As a result, the Severity, Occurrence, and Detection rate of each potential failure mode in the drug administration process for patients with lung cancer were scored using the Failure Mode and Effect Analysis (FMEA) model in this study. Then, the risk level of each failure mode and the direction of improvement were investigated using the Slacks-based measure data envelopment analysis (SBM-DEA) model. According to the findings, the medicine administration process for lung cancer patients could be classified into five links, with a total of 60 failure modes. The risk of failure modes for patient medication and post-medication monitoring ranked highly, with unauthorized use of traditional Chinese medicine and folk prescription and unauthorized drug addition (incorrect self-medication) ranking first (1/60); doctor prescription was also prone to errors. The study advises actively looking at ways to decrease the occurrence and difficulty of failure mode detection to continually enhance patient safety when using medications.
