Patients' Preference for Pharmaceutical Dosage Forms: Does It Affect Medication Adherence? A Cross-Sectional Study in Community Pharmacies

Background

Dosage forms (DF), which are primarily divided into solid, semisolid, liquid, and gaseous, are among the different factors that influence drug adherence. Thus, the purpose of this study was to evaluate how patients' preferences for pharmaceutical DF affected their adherence to medication in community pharmacies in Gondar town.

Methods

A cross-sectional study on community pharmacies was carried out from June 25 to July 27, 2023. The statistical package for social sciences, version 26, was used for data analysis. Factors associated with patient medication discontinuation were found using both bivariate and multivariate logistic regressions.

Results

According to our study, the majority of respondents (42.4%) preferred tablet DF. Most respondents (63.9%) DF preference was affected by the size of the medication, in which small-sized were most preferable (59.6%). The oral route of administration was the most preferable (71.2%). The majority of the respondents (59.9%) had a history of discontinuation of medicines. Being male (AOR=2.21, 95% CI: 1.29, 3.79), living in rural areas (AOR=1.98, 95% CI: 1.03, 3.83), types of DF (AOR=4.59, 95% CI: 1.28, 16.52), high frequency of administration (AOR=2.22, 95% CI: 1.08, 4.57), high cost of medication (AOR=3.09, 95% CI: 1.69, 5.68), getting some improvement from illness (AOR=3.29, 95% CI: 1.10, 9.87), and high number of drugs (AOR=3.29, 95% CI: 1.67, 13.85) were significantly associated with medication discontinuation.

Conclusion

Our findings showed that tablet dosage forms, oral routes of administration, and once-daily taking of medicines were the most preferred by our respondents. Being male, living in rural areas, types of DF, high frequency of administration, high cost of medication, getting some improvement from illness, and high number of drugs were significantly associated with medication discontinuation. This provides an insight into what to consider when prescribing medicine to enhance patients' adherence and overall therapeutic outcomes.

Medication Handling and Storage among Pilgrims during the Hajj Mass Gathering

We aimed to investigate the knowledge and practices of Hajj pilgrims regarding medication storage and handling during the Hajj mass gathering. In this cross-sectional study, adult pilgrims from 30 countries were interviewed using a structured questionnaire during the 2019 Hajj. The study enrolled 1221 participants with a mean age of 50.8 years (SD = 12.5, range = 18-98) and male:female ratio of 1.7:1. Most pilgrims were literate, 50.4% had a university or higher education, and 38% reported at least one underlying health condition. Most pilgrims reported receiving education regarding the proper way to store their medication during Hajj, mainly from physicians (73.7%) and pharmacists (39.4%). Although 68.2% of pilgrims had good knowledge regarding medication storage and the potential effect of inappropriate storage conditions on medications and health, inadequate knowledge and poor practice were identified among some. Level of education, having an underlying health condition and receiving health education on mediation storage were independently associated with good knowledge. Most pilgrims took their medications with them during Hajj, although storage and handling of their medication also varied depending on the stages of their Hajj pilgrimage journey. Improving Hajj pilgrims' awareness and knowledge about appropriate storage and handling of their medications are beneficial in reducing the risk of associated adverse health outcomes, both during Hajj and beyond the mass gathering.

Development and validation of medication storage and disposal questionnaire

Objectives

Inappropriate medication storage and disposal is a global problem and has a negative impact on public health, economy and the environment. One of the main causes of this problem is the lack of knowledge among the population about medication storage and disposal. This study aimed to develop a tool to measure knowledge and practice about medication storage and disposal and measure it among the Jordanian population.

Methods

This web-based cross-sectional study developed a tool to evaluate medication storage and disposal knowledge attitude and practice. Exploratory factor analysis, analysis of variance and t-test were conducted to analyze the data.

Key findings

1132 responses were collected. The exploratory factor analysis suggested a three-factor model, the three models are knowledge-need, patient-related, and medication-related factors. Knowledge-need factor evaluates the participants’ perceptions of the need for awareness and regulations regarding medication storage and disposal. The patient-related factor evaluates medication discontinuation behaviours. Medication-related factor evaluates the handling of damaged or expired medication practices. The highest mean of all three factors was for the knowledge-need factor (mean = 4.13), while the lowest was for the patient-related factor (mean = 3.22). The education level was negatively associated with patient-related factor indicating good behaviours. The means of the three factors were significantly associated with the respondents reporting that they know the correct medication storage and disposal behaviours, and the respondents believing that there are consequences of keeping medication at home.

Conclusion

The questionnaire was a valid and reliable tool to assess the knowledge and practice of medication storage and disposal. This study’s findings suggest that the lack of knowledge is the main reason behind the inappropriate medication storage and disposal practice. There is a need for awareness-improvement, which should involve healthcare awareness campaigns and governmental regulations.

Insulin Knowledge, Handling, and Storage among Diabetic Pilgrims during the Hajj Mass Gathering

BACKGROUND

Diabetes is one of the most common underlying health conditions among Hajj pilgrims. Many diabetics manage their condition using insulin, which requires appropriate storage conditions to maintain its stability and effectiveness. We aimed to investigate insulin knowledge, storage, and handling among diabetic pilgrims during Hajj to identify specific areas for improvement.

METHOD

Adult diabetic pilgrims from 22 countries were interviewed using a structured questionnaire during the 2019 Hajj.

RESULTS

The study enrolled 277 diabetic pilgrims with a mean age of 58.4 years (SD = 10.4, range: 20-83) and male : female ratio of 1.6 : 1. Most participants (86.4%) were literate and reported using insulin for a mean of 7.1 years (SD = 5.3, range: 1-23). Over 95% of pilgrims brought their insulin with them from their country of origin, where they also received most of their insulin storage information, mainly from physicians (77.8%) and pharmacists (59.6%). Pilgrims' knowledge regarding insulin storage was just above average (mean knowledge score = 0.51; SD = 0.23). Pilgrims who were literate and previously received education on insulin storage, those with a higher level of education, and those with a longer duration of insulin therapy, had significantly higher knowledge scores. Pilgrims' storage and handling of their insulin during Hajj also varied depending on the stages of their pilgrimage journey.

CONCLUSION

Inadequate knowledge and inappropriate practices regarding insulin handling and storage were identified among diabetic Hajj pilgrims, which could compromise the quality of insulin and lead to health hazards. Improving diabetic pilgrims' knowledge of diabetes management, including insulin storage, will be beneficial during the pilgrimage and beyond.
