Consumer knowledge about over-the-counter NSAIDs: they don't know what they don't know

Avoiding anti-inflammatories: a randomised controlled trial testing the effect of an eHealth information package on primary healthcare patient medication knowledge and behaviour in Aotearoa New Zealand

BACKGROUND

Patient medication knowledge and health literacy affect patient safety. Taking angiotensin-converting enzyme inhibitors (ACE-i) or angiotensin II receptor blockers (ARBs), with diuretics and non-steroidal anti-inflammatory medications (NSAIDs) is nephrotoxic. Patients may not know of this risk. An eHealth information package was developed to inform patients at risk of taking this combination of medication.

OBJECTIVE

To assess the impact of the eHealth information package on patient knowledge and behaviour.

DESIGN

This was a two-arm, parallel, randomised control trial. A knowledge quiz and NSAID use survey were undertaken at baseline, and repeated after two weeks. The intervention group accessed the information package after completing the baseline assessment. The control group received normal care.

SETTING AND PARTICIPANTS

Primary healthcare patients prescribed an ACE-i or ARB plus a diuretic in Aotearoa New Zealand.

INTERVENTION

A novel eHealth information package was made available to participants in the intervention group consisting of a downloadable PDF and online education activity. This took approximately 15 min for participants to complete.

PRIMARY OUTCOME MEASURES

Change in knowledge scores and in NSAID use between pre-intervention and post-intervention assessment.

SECONDARY OUTCOME MEASURES

Self-reported patient intentions regarding future NSAID use RESULTS: The 201 participants who completed the study had high baseline NSAID medication knowledge, which did not substantially change at follow-up. The intervention group had a 0.35 (95% CI: -0.18, 0.88) higher knowledge score than the control group. NSAID use decreased over the study; the intervention group had 62% lower odds of NSAID use at follow-up assessment compared with the control group (OR=0.37, 95% CI: 0.14, 1.03). There was no substantial difference between study groups at follow-up for self-reported action. The information package was considered acceptable and useful.

CONCLUSION

This tailored eHealth information package may reduce NSAID use in patients at increased risk from NSAID-related harm.

Consumer awareness and knowledge regarding use of non-steroidal anti-inflammatory drugs (NSAIDs) in a metropolitan area

Background

Non-steroidal anti-inflammatory drugs (NSAIDs) have well-known adverse effects, and numerous studies have shown inappropriate behaviors regarding their use. The primary aim of this study was to analyze the knowledge, attitudes, and behaviors regarding the use of NSAIDs simultaneously in one of the largest and most populated areas of Italy, Naples.

Methods

From 2021 December 14th to 2022 January 4th, a cross-sectional survey study was conducted among community centers, working places, and universities using a snowball sampling method. For inclusion in the study, the participants were required to be at least 18 years old and residents in the metropolitan area of Naples. Three multiple linear regression analysis (MLRA) models were developed by including variables that could potentially be associated with the following outcomes of interest: knowledge (Model I), attitudes (Model II), and behavior (Model III) regarding the use of NSAIDs.

Results

Data were acquired from 1,012 questionnaires administered to subjects evenly divided by gender with an average age of 36.8 years and revealed that only 7.9% of the participants self-admittedly did not take NSAIDs, while approximately half the participants (50%) admitted to occasionally using them. The results showed a statistically significant correlation between attitudes regarding the appropriate use of NSAIDs and less knowledge. The regression analyses indicated that behaviors regarding the appropriate use of NSAIDs were statistically significant in younger respondents, non-smokers, and those without children. These interesting results showed that behaviors regarding the appropriate use of NSAIDs were significantly higher among respondents with less knowledge and more positive attitudes.

Conclusion

According to the collected data and statistical analysis results, it is possible to identify factors that can greatly affect inappropriate behaviors regarding the use of NSAIDs and establish targeted prevention programs.

Attitudes, attributions, and usage patterns of primary care patients with regard to over-the-counter drugs-a survey in Germany

Studies show that over-the-counter drugs are widely used by consumers. Moreover, there is a huge selection available and they are prominently featured in advertising. To date, there exist only a few studies that shed light on the attitudes, attributions, and usage patterns of patients with regard to use of over-the-counter drugs. An anonymized explorative waiting room survey was conducted among 900 patients in 60 GP practices in the German states of North Rhine-Westphalia, Hesse, and Rhineland-Palatinate. As well as the descriptive analysis, a t test was applied to independent random samples, in order to identify significant differences between two groups. 65% of respondents reported using over-the-counter drugs frequently or occasionally. With regard to effects, risks, and side effects, 54% state that they usually take advice from their GP and/or pharmacist before purchasing or taking over-the-counter preparations. For 56%, the package information leaflet is a frequent source of information about the over-the-counter drugs used. The respondents consider over-the-counter preparations to be particularly suitable for (preventive) treatment of colds, flu symptoms, and pain management. The widespread perception of over-the-counter drugs as simple to use (62%), low-dose (69%), and low-efficacy (73%) products does not always correspond to the actual capabilities and risks of over-the-counter self-medication. Given the easy availability of over-the-counter drugs and their strong presence in advertising, it is important that patients have a realistic idea of the capabilities and risks of over-the-counter products. In addition to the advice provided by pharmacists, the trusting, long-standing support provided by GPs and their ongoing information and advice services play a central role in this. It would be advisable to give more attention to this public health concern and to promote initiatives to make patients more aware of the risks regarding consumption of drugs without medical consultation.

Charting the Knowledge and Patterns of Non-Steroidal Anti-Inflammatory Drugs Usage in Hail Population, Saudi Arabia: Insights into the Adverse Effect Profile

(1) Background: It is crucial to provide safe and knowledgeable healthcare practices because no research has been performed on the knowledge and usage patterns of NSAIDs among the Hail population. (2) Method: Structured questionnaires were utilized to gather data from 399 individuals in Hail, Saudi Arabia, for the cross-sectional analysis. The study assessed participants' knowledge regarding NSAIDs, patterns of use, reasons for use, and awareness of potential side effects. (3) Results: In the study, the gender distribution indicated that 170 participants (42.61%) were male, whereas 229 (57.39%) were female. Gender, occupation, and marital status showed non-significant associations except for menstrual cycle and joint pain, where marital status displayed significant associations (p > 0.001). Education and monthly income exhibited non-significant associations for all these reasons. The regression analysis demonstrated that gender played a significant role, with females having higher odds of knowledge (AOR = 1.75, 95% CI 1.10-2.88) than males. Meanwhile, >50% of the participants had knowledge of adverse events related to the use of NSAIDs, whereas 25% had no knowledge. Moreover, 59 (25.76%) participants reported discomfort with the use of NSAIDs. In addition, 50% and >75% of respondents believed that NSAIDs could induce peptic ulcers and kidney damage, respectively. (4) Conclusions: This study shed light on the knowledge and patterns of NSAIDs use in the population of Hail, Saudi Arabia. Healthcare providers and policymakers should consider these insights to develop targeted educational initiatives and healthcare interventions to promote safe and informed NSAID utilization in the region.

Evaluation of the knowledge, practices, and attitudes of community pharmacists towards adverse effects of non-steroidal anti-inflammatory drugs (NSAIDs): a cross-sectional study

BACKGROUND

Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most commonly used over-the-counter medications for the treatment of pain, fever, and inflammation. Gastrointestinal problems and renal complications are the most frequently observed adverse effects associated with NSAID usage. Therefore, this study aims to evaluate the levels of knowledge, attitude, and practice regarding the adverse effects of non-prescription NSAIDs among community pharmacists in Egypt.

METHODS

A 4-month cross-sectional survey, including licenced community pharmacists in Egypt, was conducted. The anonymous Google Forms survey was accompanied by a cover letter explaining its purpose. The survey link was sent to 2000 verified community pharmacist email addresses with clear instructions to complete and submit the questionnaire within 3 weeks. Descriptive and inferential statistical analyses were conducted using IBM-SPSS version 26. The means of variables were compared using analysis of variance test. Pearson correlation was employed to assess the level of linear association between the overall knowledge, practice, and attitude scores. P-value ≤ 0.05 was considered statistically significant.

RESULTS

Approximately 80% of community pharmacists in Egypt exhibit moderate-to-good knowledge regarding the adverse effects of NSAIDs. Additionally, 60.6% of them demonstrated a positive attitude and 80.9% showed moderate-to-good practice scores towards preventing such adverse effects. The education level was the only demographic factor with significant effects on the NSAIDs-related knowledge, practice, and attitude scores. Community pharmacists primarily rely on internet sources for knowledge updates. Additionally, there was a significant positive linear correlation between knowledge and attitude (r = 0.384, P < 0.001), knowledge and practice (r = 0.178, P < 0.001), and between attitude and practice (r = 0.311, P < 0.001) among the participants.

CONCLUSION

Community pharmacists have a vital responsibility to perform screenings, assess patient risk elements, and share knowledge to guarantee the appropriate and safe utilisation of NSAIDs. Given that internet sources are presently the most accessible and used sources of information, governmental directions should prioritise the establishment and enhancement of freely accessible drug information sources for community pharmacists. Further research is necessary to assess the effectiveness of counselling and appropriate guidance provided by community pharmacies in promoting safe and proper drug usage.

Benchmarking different docking protocols for predicting the binding poses of ligands complexed with cyclooxygenase enzymes and screening chemical libraries

Introduction

Non-steroidal anti-inflammatory drugs (NSAIDs) constitute an important class of pharmaceuticals acting on cyclooxygenase COX-1 and COX-2 enzymes. Due to their numerous severe side effects, it is necessary to search for new selective, safe, and effective anti-inflammatory drugs. In silico design of novel therapeutics plays an important role in nowadays drug discovery pipelines. In most cases, the design strategies require the use of molecular docking calculations. The docking procedure may require case-specific condition for a successful result. Additionally, many different docking programs are available, which highlights the importance of identifying the most proper docking method and condition for a given problem.

Methods

In the current work, the performances of five popular molecular docking programs, namely, GOLD, AutoDock, FlexX, Molegro Virtual Docker (MVD) and Glide to predict the binding mode of co- crystallized inhibitors in the structures of known complexes available for cyclooxygenases were evaluated. Furthermore, the best performers, Glide, AutoDock, GOLD and FlexX, were further evaluated in docking-based virtual screening of libraries consisted of active ligands and decoy molecules for cyclooxygenase enzymes and the obtained docking scores were assessed by receiver operating characteristics (ROC) analysis.

Results

The results of docking experiments indicated that Glide program outperformed other docking programs by correctly predicting the binding poses (RMSD less than 2 Å) of all studied co-crystallized ligands of COX-1 and COX-2 enzymes (i.e., the performance was 100%). However, the performances of the other studied docking methods for correctly predicting the binding poses of the ligands were between 59% to 82%. Virtual screening results treated by ROC analysis revealed that all tested methods are useful tools for classification and enrichment of molecules targeting COX enzymes. The obtained AUCs range between 0.61-0.92 with enrichment factors of 8 - 40 folds.

Conclusion

The obtained results support the importance of choosing appropriate docking method for predicting ligand-receptor binding modes, and provide specific information about docking calculations on COXs ligands.

Label-Free Digital Holotomography Reveals Ibuprofen-Induced Morphological Changes to Red Blood Cells

Understanding the dose-dependent effect of over-the-counter drugs on red blood cells (RBCs) is crucial for hematology and digital pathology. Yet, it is challenging to continuously record the real-time, drug-induced shape changes of RBCs in a label-free manner. Here, we demonstrate digital holotomography (DHTM)-enabled real-time, label-free concentration-dependent and time-dependent monitoring of ibuprofen on RBCs from a healthy donor. The RBCs are segmented based on three-dimensional (3D) and four-dimensional (4D) refractive index tomograms, and their morphological and chemical parameters are retrieved with their shapes classified using machine learning. We directly observed the formation and motion of spicules on the RBC membrane when aqueous solutions of ibuprofen were drop-cast on wet blood, creating rough-membraned echinocyte forms. At low concentrations of 0.25-0.50 mM, the ibuprofen-induced morphological change was transient, but at high concentrations (1-3 mM) the spiculated RBC remained over a period of up to 1.5 h. Molecular simulations confirmed that aggregates of ibuprofen molecules at high concentrations significantly disrupted the RBC membrane structural integrity and lipid order but produced negligible effect at low ibuprofen concentrations. Control experiments on the effect of urea, hydrogen peroxide, and aqueous solutions on RBCs showed zero spicule formation. Our work clarifies the dose-dependent chemical effects on RBCs using label-free microscopes that can be deployed for the rapid detection of overdosage of over-the-counter and prescribed drugs.

Elevating Safe Use of Over-The-Counter Medications in Older Adults: A Narrative Review of Pharmacy Involved Interventions and Recommendations for Improvement

Over-the-counter (OTC) medications are products that have been made easily accessible to allow patients to treat common ailments without a prescription and the cost of a doctor's visit. These medications are generally considered safe; however, there is still a potential for these medications to lead to adverse health outcomes. Older adults (ages 50+) are especially susceptible to these adverse health outcomes, due to age-related physiological changes, a higher prevalence of comorbidities, and prescription medication use. Many OTC medications are sold in pharmacies, which provides pharmacists and technicians with the opportunity to help guide safe selection and use for these medications. Therefore, community pharmacies are the ideal setting for OTC medication safety interventions. This narrative review summarizes the findings of pharmacy-involved interventions that promote safe OTC medication use for older adults.

Over the Counter Pain Medications Used by Adults: A Need for Pharmacist Intervention

BACKGROUND

The safety of pharmacotherapy for geriatric patients is an essential aspect of the demographic perspective in view of the increasing size of this population. Non-opioid analgesics (NOAs) are among the most popular and often overused over-the-counter medications (OTC). The reasons for drug abuse are common in the geriatric population: musculoskeletal disorders, colds, inflammation and pain of various origins. The popularity of self-medication and the ability to easily access OTC drugs outside the pharmacy creates the danger of their misuse and the incidence of adverse drug reactions (ADRs). The survey included 142 respondents aged 50-90 years. The relationship between the prevalence of ADRs and the NOAs used, age, presence of chronic diseases, and place of purchasing and obtaining information about the mentioned drugs were evaluated. The results of the observations were statistically analyzed using Statistica 13.3. The most commonly used NOAs among the elderly included paracetamol, acetylsalicylic acid (ASA) and ibuprofen. Patients consumed the medications for intractable headaches, toothaches, fevers, colds and joint disorders. Respondents indicated the pharmacy as the main location for purchasing medications, and the physician as the source of information for selecting the therapy. ADRs were reported most frequently to the physician, and less frequently to the pharmacist and nurse. More than one-third of respondents indicated that the physician during the consultation did not take a medical history and did not ask about concomitant diseases. It is necessary to extend pharmaceutical care to geriatric patients that includes advice on adverse drug reactions, especially drug interactions. Due to the popularity of self-medication, and the availability of NOAs, long-term measures should be taken to increase the role of pharmacists in providing effective, safe health care to seniors. We are targeting pharmacists with this survey to draw attention to the problem of the prevalence of selling NOAs to geriatric patients. Pharmacists should educate seniors about the possibility of ADRs and approach patients with polypragmasy and polypharmacy with caution. Pharmaceutical care is an essential aspect in the treatment of geriatric patients, which can contribute to better results in their existing treatment and increase the safety of medication intake. Therefore, it is important to improve the development of pharmaceutical care in Poland in order to enhance patient outcomes.

Pattern of use and awareness of side-effects of non-steroidal anti-inflammatory drugs in the Jordanian population

Background: Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly utilized to reduce pain, inflammation, and fever. This study aimed to assess patterns of use and awareness of NSAID-related side-effects in an adult Jordanian. And the associations with sociodemographic factors. Methods: This cross-sectional study among a representative sample of 604 adults >18 years. A validated, self-administered questionnaire was used to collect basic sociodemographic data from the participants, as well as information regarding NSAID use. Results: Most respondents were NSAID users (65.7%), female (53.4%) and under 50 years of age (74.5%). Overall, 42.6% had been prescribed NSAIDs by a physician. Male gender and smoking were negatively correlated with NSAIDs use (multivariable odds ratio [OR]: 0.5, 95% confidence interval [CI]: 0.4-0.8, p = 0.001 and OR: 0.6, 95% CI 0.4-0.8, p = 0.003). In contrast, the Ministry of Health Insurance was associated with NSAIDs use with OR: 1.6, 95% CI: 1.1-2.6, p = 0.03. Overall, 65.1% were aware of kidney NSAID-related side-effects and 22.4% were aware of the increased risk of asthma and allergy. Conclusion: Despite the high frequency of NSAID use in the Jordanian general population, there is limited knowledge of their side-effects as well as drug interactions. This is cause for concern, particularly as many participants reported having been prescribed NSAIDs by physicians without adequate patient safety education.

Risk of Bleeding Among Individuals on Direct-Acting Oral Anticoagulants: An Academic Medical Center Cohort Study

ABSTRACT

Previous research has identified risk factors that may affect the risk of bleeding when individuals are exposed to oral anticoagulants. It is unclear if the risk continues to exist with the direct oral anticoagulants (DOACs). The purpose of this study was to assess the risk of bleeding in patients on DOACs (apixaban, rivaroxaban, dabigatran, edoxaban, and betrixaban) based on known risk factors including demographics, medical conditions, and concomitant medications. This study was a retrospective analysis using electronic health record data from the University of Utah Hospital (Division of Cardiovascular Medicine) of individuals receiving a DOAC from 2015 to 2020. The primary outcome of interest was bleeding events [gastrointestinal (GI) bleeding, other anatomical site bleeding (excluding GI), and any bleeding] recorded in the electronic health record that codes using International Classification of Diseases 9th and 10th codes. Known risk factors were used to predict bleeding using multivariate logistic regression. A total of 5492 patients received a DOAC during the study period. Less than half the study population were female (2287, 41.6%). During the follow-up, there were 988 patients (18.0%) experiencing a bleeding event. Of them, 351 patients (35.5%) had a GI bleeding event. Significant risk factors of GI bleeding included clopidogrel [odds ratio (OR) 1.71; 95% confidence interval (95% CI), 1.16-2.52] and previous GI bleeding episodes (OR 7.73; 95% CI, 5.36-11.16). Exposure to corticosteroids (OR 1.50; 95% CI, 1.20-1.87) and previous GI bleeding (OR 1.61; 95% CI, 1.10-2.35) were associated with an increase in bleeding at other anatomical sites (not GI included).

Shared Decision-Making for Drug-Drug Interactions: Formative Evaluation of an Anticoagulant Drug Interaction

Background

Warnings about drug-drug interactions (DDIs) between warfarin and nonsteroidal anti-inflammatory drugs (NSAIDs) within electronic health records indicate potential harm but fail to account for contextual factors and preferences. We developed a tool called DDInteract to enhance and support shared decision-making (SDM) between patients and physicians when both warfarin and NSAIDs are used concurrently. DDInteract was designed to be integrated into electronic health records using interoperability standards.

Objective

The purpose of this study was to conduct a formative evaluation of a DDInteract that incorporates patient and product contextual factors to estimate the risk of bleeding.

Methods

A randomized formative evaluation was conducted to compare DDInteract to usual care (UC) using physician-patient dyads. Using case vignettes, physicians and patients on warfarin participated in simulated virtual clinical encounters where they discussed the use of taking ibuprofen and warfarin concurrently and determined an appropriate therapeutic plan based on the patient’s individualized risk. Dyads were randomized to either DDInteract or UC. Participants completed a postsession interview and survey of the SDM process. This included the 9-item Shared Decision-Making Questionnaire (SDM-Q-9), tool usability and workload National Aeronautics and Space Administration (NASA) Task Load Index, Unified Theory of Acceptance and Use of Technology (UTAUT), Perceived Behavioral Control (PBC) scale, System Usability Scale (SUS), and Decision Conflict Scale (DCS). They also were interviewed after the session to obtain perceptions on DDInteract and UC resources for DDIs.

Results

Twelve dyad encounters were performed using virtual software. Most (n=11, 91.7%) patients were over 50 years of age, and 9 (75%) had been taking warfarin for more than 2 years (75%). Regarding scores on the SDM-Q-9, participants rated DDInteract higher than UC for questions pertaining to helping patients clarify the decision (P=.03), involving patients in the decision (P=.01), displaying treatment options (P<.001), identifying advantages and disadvantages (P=.01), and facilitating patient understanding (P=.01) and discussion of preferences (P=.01). Five of the 8 UTAUT constructs showed differences between the 2 groups, favoring DDInteract (P<.05). Usability ratings from the SUS were significantly higher (P<.05) for physicians using DDInteract compared to those in the UC group but showed no differences from the patient’s perspective. No differences in patient responses were observed between groups using the DCS. During the session debrief, physicians indicated little concern for the additional time or workload entailed by DDInteract use. Both clinicians and patients indicated that the tool was beneficial in simulated encounters to understand and mitigate the risk of harm from this DDI.

Conclusions

Overall, DDInteract may improve encounters where there is a risk of bleeding due to a potential drug-drug interaction involving anticoagulants. Participants rated DDInteract as logical and useful for enhancing SDM. They reported that they would be willing to use the tool for an interaction involving warfarin and NSAIDs.

Diclofenac removal by the microalgae species Chlorella vulgaris, Nannochloropsis oculata, Scenedesmus acutus, and Scenedesmus obliquus

In this work, we evaluated the removal efficiency of diclofenac by Chlorella vulgaris OW-01, Nannochloropsis oculata CCAP 849/7, Scenedesmus acutus UTEX 72, and Scenedesmus obliquus CCAP 276/2. Each microalga was grown in media with different concentrations (50 and 100% of the original formulation) of carbon, nitrogen, and phosphorus, to evaluate their effect on the removal of diclofenac. We also evaluated the photodegradation of diclofenac under the same conditions. The diclofenac removed from the media ranged from 59 to 92%, obtaining the highest removal with S. obliquus. The diclofenac adsorbed on the cell walls ranged from 12.2 to 26.5%, obtaining the highest adsorption with S. obliquus. The diclofenac degraded by light ranged from 15 to 28%. The nutrient deficit showed no influence on the removal of diclofenac in any of the microalgae under study. These results indicate that S. obliquus is the best alternative for the bioremediation of diclofenac.

Over-the-counter drug use in suicidal/self-harm behavior: Scoping review

Background and aims

Minor physical ailments are treated with over-the-counter (OTC) medications. The availability of OTC drugs helps reduce waiting times and ease the suffering of many. Suicidal behavior includes suicidal ideation, attempts, and completed suicides and affects people of all ages, religions, and cultures. This study aims to review use of OTC drugs for self-harm and suicidal attempts.

Methods

We reviewed English language publications from the beginning of time to October 2021 on OTC drug use for suicidal behavior.

Results

Twenty-seven studies met the eligibility criteria, and 1,816,228 participants were reported in these publications. OTC analgesics and sedatives/hypnotics were frequently used for suicidal behavior. Females and young people mainly were reported to self-harm using OTC medications. An increase in OTC analgesic use for self-harm in adolescents during the school months was reported. Elderly persons use hypnotics more frequently for suicidal attempts. Persons with major psychiatric disorders were reported to use OTC for suicidal behavior.

Conclusion

The available information shows that the prevention strategies should focus on OTC analgesics and hypnotic use among women, the young, the elderly, and persons with mental health disorders.

Engaging consumers in wise use of over-the-counter medications in Taiwan: Development and evaluation of a structured medication counseling approach

OBJECTIVE

To evaluate the impact of a tailored Symptom Allergy Indication Direction Self-care (SAIDS) counseling by pharmacists on consumers' correct understanding of over-the-counter (OTC) medication use.

METHODS

This study used a time-based sampling of two independent cohorts at a single community pharmacy in Taiwan for two years beginning in December 2018. In the control cohort, participants received conventional counseling for the OTCs they selected. In the intervention cohort, participants received SAIDS counseling along with pointing out OTC package label instructions. A paper-and-pencil survey was administered face-to-face to evaluate participants' understanding for the correct use of OTCs. Descriptive statistics and chi-square tests were used to evaluate the effect of the SAIDS approach on cohorts' understanding of OTC use.

RESULTS

Compared with conventional OTC counseling, participants reported better understanding regarding potential side effects of OTCs that they acquired (p < 0.001) and were more aware of strategies to cope with the associated side effects (p < 0.001).

CONCLUSIONS AND PRACTICE IMPLICATIONS

Despite the time constraints that pharmacists often can offer to each customer, the SAIDS counseling approach may refine the structure and effectiveness of pharmacists' OTC counseling skills and thereby improve consumers' understanding of their ailments and self-care medications in Taiwan.

Knowledge, Information Sources, and Institutional Trust of Patients Regarding Medication Use in Pregnancy: A Systematic Review

Objective: The objective of our study is to characterize the knowledge, information sources, and institutional trust of patients regarding medication use in pregnancy. Materials and methods: We conducted a review of three databases: MEDLINE, EMBASE, and CINAHL. We included observational studies and knowledge assessments that examined the knowledge, attitudes, beliefs or information sources of pregnant patients related to medication use during pregnancy. Extraction was completed by two independent reviewers, outcomes were summarized descriptively, and appraisal was conducted. Results: Of the 1359 search results, 34 studies met inclusion criteria. Thus, our systematic review encompasses the beliefs of 11,757 pregnant participants. In most studies, participants described apprehension regarding potential risks to the fetus and the inadequacy of safety information. Across the 23 knowledge assessments, the majority of studies reported patient misconceptions about prescription medication in pregnancy. The most preferred information source was a healthcare provider. However, many participants expressed frustration, mistrust, and skepticism regarding physician knowledge. A common source of mistrust was due to perceived physician self-interest as well as a lack of education tailored to pregnancy. Consequently, informal sources of information were also popular. Conclusion: There is a need to improve the health literacy and trust among pregnant patients regarding drug prescribing. There are modifiable risk factors for mistrust that require further attention.

A Scoping Review of Non-Medical and Extra-Medical Use of Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)

Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most commonly used medications worldwide and have analgesic, antipyretic and anti-inflammatory properties. Although NSAIDs are recognised as generally safe and effective, non-medical and extra-medical use of these products can occur. Unlike the use of illegal and many prescription drugs, which are subject to extensive research attention, inappropriate use of NSAIDs has been less well investigated. This scoping review collates and describes what is known regarding non-medical and extra-medical use of NSAIDs. In total, 72 studies were included in this scoping review. Three themes emerged from the review: (1) indicative profile of people who engage in non-medical or extra-medical use of NSAIDs; (2) antecedents for non-medical or extra-medical use; and (3) adverse health effects of non-medical and extra-medical use of NSAIDs. The review concluded that there is a need for enhanced patient education, including among sports people; pharmacovigilance in terms of clinician recognition of aberrance; and prescriber and pharmacist awareness of the potential for extra-medical and non-medical use and the related health harms.

Using an Information Package to Reduce Patients' Risk of Renal Damage: Protocol for a Randomized Feasibility Trial

Background

Non-steroidal anti-inflammatory drugs (NSAIDs) are a common cause of renal damage, especially when taken together with angiotensin-converting enzyme inhibitors (ACE-i) or angiotensin II receptor blockers (ARBs) plus a diuretic — a combination known as the “triple whammy.” New Zealand patients are at high risk of the “triple whammy” because they can easily purchase NSAIDs without a prescription and in nonpharmacy retail settings (eg, the supermarket), there is no legal requirement to include patient information sheets with medication, and direct-to-consumer drug advertising is permitted. A patient information package has been developed for those at greatest risk of the “triple whammy,” consisting of a printable PDF and an interactive online learning activity. This information package aims to inform patients about their elevated risk of harm from NSAIDS and discourage use of NSAIDs. A randomized control trial was planned to assess the effect of the information package.

Objective

This study aims to pilot the trial procedures for recruiting patients and providing patient information online and to assess the acceptability of the patient information package.

Methods

A two-armed randomized feasibility trial will be undertaken in Northland, New Zealand. We will recruit 50 patients who are at least 18 years old from those who have signed up to receive email alerts through their general practice. Patients eligible for this study have been prescribed an ACE-i or ARB plus a diuretic in the past 3 months. They will be randomly allocated to 2 study arms. The intervention arm will receive access to an information package plus usual care; the control arm will receive usual care alone. Online surveys will be used to assess NSAID knowledge and NSAID use at baseline and after 2 weeks for both arms. The intervention arm will also evaluate the information package in an additional survey based on Normalization Process Theory (NPT) concepts. We will report the number and proportion of participants who are eligible and consent to participate in the trial. Response and drop-out rates will be reported for each trial arm. The numbers of patients who interact with the education package will be reported together with the patient evaluation of it.

Results

Funding has been obtained from the Health Research Council of New Zealand (HRC 18-031). The University of Otago Human Research Ethics Committee (H21/016) has approved this trial. Consultation has been undertaken with The Ngai Tahu research consultation committee. The trial commenced on April 12, 2021.

Conclusions

This feasibility trial will test the study processes prior to commencing a randomized controlled trial and will determine the acceptability of the patient information package. We anticipate this work will provide useful information for other researchers attempting similar work.

What Do Young Adults Think about the Safety of Over-the-Counter Analgesics? Findings from a Cross-Sectional Survey

Analgesics are commonly used over-the-counter (OTC) medicines readily available for purchase, sometimes without advice of a health professional. However, analgesics can cause harm even when taken according to dosing recommendations. Young adults may be more vulnerable to harm if they perceive low risk with OTC analgesic use, or struggle to interpret dosing instructions. This study aimed to explore factors affecting how young adults use OTC analgesics and associated perceptions of safety. An online survey was distributed to school-leavers and university students (17 to 25 years), in South-East Queensland, Australia, in the period November-December 2019. Most of the 302 respondents (school-leavers n = 147, university students n = 155) did not use analgesics frequently. School-leavers deferred to parents for analgesic information, while university students preferred the internet. The majority of respondents appeared safety conscious and did not take outside indicated use or instructions. However, a small proportion reported taking analgesics for an inappropriate indication. The difference in preferred source of analgesic information may reflect experience with analgesic use, increasing autonomy or decreased parental influence. Whilst it is encouraging that the majority of young adults appeared safety conscious, greater insight is needed into factors influencing decision making on OTC use, e.g., medicines knowledge, and changes with increasing age.

Guidance impact on primary care prescribing rates of simple analgesia: an interrupted time series analysis in England

BACKGROUND

In March 2018, NHS England published guidance for clinical commissioning groups (CCGs) to encourage implementation of policy to reduce primary care prescriptions of over-the-counter medications, including simple analgesia.

AIM

To investigate the impact of guidance publication on prescribing rates of simple analgesia (oral paracetamol, oral ibuprofen, and topical non-steroidal anti-inflammatory drugs) in primary care; CCG guidance implementation intentions; and whether the guidance has created health inequality based on socioeconomic status.

DESIGN AND SETTING

Interrupted time series analysis of primary care prescribing data in England.

METHOD

Practice-level prescribing data from January 2015 to March 2019 were obtained from NHS Digital. Interrupted time series analyses were used to assess the association of guidance publication with prescribing rates. The association between practice-level prescribing rates and Index of Multiple Deprivation scores before and after publication was quantified using multivariable Poisson regression. Freedom of information requests were submitted to all CCGs.

RESULTS

There was a statistically significant 4.4% reduction in prescribing of simple analgesia following guidance publication (adjusted incidence rate ratio 0.96, 95% CI = 0.92 to 0.99, P = 0.027), adjusting for underlying time trend and seasonality. There was considerable diversity across CCGs in whether or how they chose to implement the guidance. Practice-level prescribing rates were greater in more deprived areas.

CONCLUSION

Guidance publication was associated with a small reduction in the prescribing rates of simple analgesia across England, without evidence of creating additional health inequality. Careful implementation by CCGs would be required to optimise cost saving to the NHS.

Drug-related problems and pharmacy interventions in non-prescription medication, with a focus on high-risk over-the-counter medications

Background The risks associated with over-the-counter medication are often underestimated by consumers. The incorrect use of certain medications can lead to significant patient harm. Inappropriate use can be prevented by pharmaceutical counselling. Objective To determine the number and nature of drug-related problems in over-the-counter medication with a special emphasis on high-risk over-the-counter medications. Setting Fifty-two community pharmacies in Finland. Method This observational study was conducted as a questionnaire survey. The pharmacists working in participating pharmacies documented the observed drug-related problems and pharmacy interventions in over-the-counter medication during 1 week using an electronic study form based on the Westerlund drug-related problem classification system. Main outcome measure The prevalence of drug-related problems and problem types in different medication categories. Results The 52 community pharmacies documented 339 drug-related problems in 0.6% of over-the-counter customers, the most common problem being “Uncertainty about the indication for the drug” (39.2%). A significant proportion of the documented problems (26.3%) concerned high-risk over-the-counter medications, and the majority of these cases were associated with non-steroidal anti-inflammatory drugs (21.8%). In total, pharmacies made 641 interventions to resolve the drug-related problems. For majority of drug-related problems (87%), pharmacist’s intervention involved counselling. In more than half of the problem cases, the pharmacy intervention was precautionary. Conclusion Pharmacists intervene in and prevent problems related to over-the-counter medications, including high-risk medications like analgesics, in which inappropriate use due to consumers’ lack of knowledge can lead to severe consequences. As the selection and use of over-the-counter medications is continuously increasing, pharmaceutical counselling should be readily available and actively provided for consumers to achieve safer self-medication.

Avoiding acute kidney injury in primary care: attitudes and behaviours of general practitioners and community pharmacists in Hawke’s Bay

ABSTRACT INTRODUCTIONAwareness of the effect of acute kidney injury on patient outcomes and health systems is growing internationally. New Zealand’s approach focuses on stopping consumption of ‘at-risk’ medicines when acute kidney injury has been established and raising awareness of the risks associated with the Triple Whammy drug combination. AIMTo explore current practices and views of Hawke’s Bay general practitioners (GPs) and community pharmacists regarding patient education about medicines with potential for contributing to community-acquired acute kidney injury, with a focus on community pharmacists providing patient education regarding when to temporarily withhold ‘at-risk’ medicines during acute dehydrating illnesses. METHODSTwo tailored cross-sectional online anonymous surveys of GPs and community pharmacists working in Hawke’s Bay were administered between 2015 and 2016. Descriptive statistics were generated from the closed-question responses and manifest content analysis was applied to the free-text responses. RESULTSTwenty-two percent (37/167) of GPs and 34% (32/95) of pharmacists responded. Most respondents, GPs (34/37) and pharmacists (25/32), self-reported expertise to educate patients on temporarily withholding ‘at-risk’ medicines during acute dehydrating illnesses. Twenty-nine (78%) GPs had confidence in pharmacists providing this patient education and 20 (54%) welcomed pharmacist contact regarding a Triple Whammy prescription. However, for a variety of reasons, pharmacists did not routinely provide this education or contact GPs. DISCUSSIONBoth GPs and community pharmacists reported they had expertise to provide useful patient education about ‘at-risk’ medicine use during acute dehydrating illnesses. Dialogue to clarify the role of the two groups would be beneficial to achieve a more coordinated approach to patient care. Relevant strategies and frameworks already exist, but national interprofessional leadership and local application would be beneficial.

Not all (N)SAID and done: Effects of nonsteroidal anti-inflammatory drugs and paracetamol intake on platelets

Platelets are key mediators of hemostasis and thrombosis and can be inhibited by nonsteroidal anti-inflammatory drugs (NSAIDs). As a result, platelet donors are temporarily deferred from donating if they have recently taken NSAIDs such as aspirin or ibuprofen. Despite these measures, a proportion of platelet donations show exposure to these drugs; however, little is known about the effect of NSAIDs and their metabolites on platelet quality in vivo and during storage. In this review, the effect of NSAIDs on platelet function is summarized, with a focus on the widely consumed over-the-counter (OTC) medications aspirin, ibuprofen, and the non-NSAID paracetamol. Aspirin and ibuprofen have well-defined antiplatelet effects. In comparison, studies regarding the effect of paracetamol on platelets report variable findings. The timing and order of NSAID intake is important, as concurrent NSAID use can inhibit or potentiate platelet activation depending on the drug taken. NSAID deferral periods and maximum platelet shelf-life is set by each country and are revised regularly. Reduced donor deferral periods and longer platelet storage times may affect the quality of platelet products, and it is therefore important to identify the possible impact of NSAID intake on platelet quality before and after storage.

Practices of healthcare professionals in communicating with nonsteroidal anti-inflammatory drug users in Thailand: a qualitative study

OBJECTIVE

This study aimed to explore practices among healthcare professionals in nonsteroidal anti-inflammatory drug (NSAID) information provision.

METHODS

In-depth interviews were conducted with orthopaedic physicians (OPs), hospital and community pharmacists (CPs) in northeastern Thailand. Ten hospitals and 20 pharmacies in five provinces were purposively selected. Interviews followed a topic guideline, were audio-recorded, transcribed verbatim and analysed using a framework approach.

KEY FINDINGS

Fifty-one participants were involved: 13 OPs, 20 hospital pharmacists and 18 CPs. Four main themes emerged: general information, safety information, differences between new and regular NSAID users and non-selective and selective NSAID users. Pharmacists mostly provided information on administration and indication. While all three groups informed of adverse effects, this was selective, related to factors including trading, time available, patients' age and perceived ability to understand. Gastrointestinal adverse effect information was most commonly provided, with other side effects, drug interactions and need to monitor for adverse effects rarely mentioned. Variation was reported in provision of safety information depending on whether patients were using selective or non-selective NSAIDs, and new or long-term users.

CONCLUSIONS

The content and frequency of NSAID information provision varied between health professionals. Greater awareness of NSAID risks is essential; therefore, strategies to improve information provision to Thai patients are desirable.

Expanding the role of Australian pharmacists in community pharmacies in chronic pain management - a narrative review

Chronic pain is a condition where patients continuously experience pain symptoms for at least 3 to 6 months. It is one of the leading causes of disabilities across the globe. Failure to adequately manage chronic pain often results in additional health concerns that may directly contribute to the worsening symptoms of pain. Community pharmacists are an important healthcare resource that contributes to patient care, yet their roles in chronic pain management are often not fully utilised. This review aimed to investigate and explore pharmacist-driven chronic pain educational and medication management interventions in community pharmacies on an international level, and thereby identify if there are potential benefits in modelling and incorporating these interventions in the Australian community. We found a number of studies conducted in Europe and the United States investigated the benefits of pharmacist-driven educational and medication management interventions in the context of chronic pain management. Results demonstrated that there were improvements in the pain scores, depression/anxiety scales and physical functionality in patient groups receiving the pharmacist driven-interventions, thereby highlighting the clinical benefit of these interventions in chronic pain. In conclusion, pharmacists are trustworthy and responsible advocates for medication reviews and patient education. There are currently very limited formal nationally recognised pharmacist-driven intervention programs dedicated to chronic pain management in Australian community pharmacies. International studies have shown that pharmacist-driven chronic pain interventions undertaken in community pharmacies are of benefit with regards to alleviating pain symptoms and adverse events. Furthermore, it is also clear that research around the application of pharmacist-led chronic pain interventions in Australia is lacking. Modelling interventions that have been conducted overseas may be worth exploring in Australia. The implementation of similar intervention programs for Australian pharmacists in community pharmacies may provide enhanced clinical outcomes for patients suffering from chronic pain. The recently implemented Chronic Pain MedsCheck Trial may provide some answers.

IPADAM "Pharmaceutical interventions on the issue of pharmaceutical records and self-medication" quanti survey in 482 French pharmacies

OBJECTIVES

This study aims to: (i) quantify the number of pharmaceutical interventions (PIs) linked to spontaneous requests for the two oral target molecules, ibuprofen and pseudoephedrine (ii) analyse the causes and proposed solutions (iii) quantify the number of registrations in the patient's pharmaceutical record and identify the various causes of non-registration.

METHODS

The study was conducted over a 2 weeks' period in the months of February and April 2014 in 482 pharmacies affiliated to the training supervisor associations of 8 French Faculties of Pharmacy. Data regarding spontaneous requests for the target molecules was collected, with due respect to a patient care flow chart at the pharmacy, by incorporating the systematic proposal for registration of the medication in the patient's pharmaceutical record. Each PI was the subject of a notification made with reference to a standardized grid.

RESULTS

A total of 12,160 dispensations were made over the two weeks of the study. Overall 815 of them gave rise to an PI (6.7%), justified in almost half of the cases by a contraindication. The alternative proposed by the dispensing pharmacist was accepted in more than 9 out of 10 cases. In half of the cases, the dispensing pharmacist had access to the patient's French healthcare card; more than 2/3 of the dispensations thus led to the registration of the medication in the patient's pharmaceutical record.

CONCLUSION

The pairing of the two tools, these being the notification grid and the pharmaceutical record, aims to maximize dispensation security while patients are being guided in their approach to self-medication.

Development of a Theory-Based Intervention to Enhance Information Exchange during Over-The-Counter Consultations in Community Pharmacy

(1) Background: Community pharmacy personnel help mitigate risks of self-care by consumers who seek over-the-counter (OTC) medicines or treatment of symptoms and/or conditions. Exchange of information facilitates the OTC consultation, but pharmacy personnel often report difficulties in engaging consumers in a dialogue. The aim of this study was to describe the development of a behaviour change intervention to enhance information exchange between pharmacy personnel and consumers during OTC consultations in community pharmacies. (2) Methods: The Behaviour Change Wheel methodological framework was used to link factors that influence consumer engagement with information exchange during OTC consultations with intervention functions to change behaviour. Options generated were rationalized and the final intervention strategy was derived. (3) Results: Education, persuasion, environmental restructuring, and modelling were determined to be potential intervention functions. The intervention incorporated placing situational cues in the form of posters in the community pharmacy modelling information exchange behaviour, persuading through highlighting the benefits of exchanging information and educating about its importance. (4) Conclusions: A systematic, theoretically underpinned approach was applied to develop candidate interventions to promote information exchange in OTC consultations. The feasibility and efficacy of the intervention strategy has since been tested and will be reported elsewhere.

What do Australian & New Zealand caregivers know about children's ibuprofen? The results of an online survey?

Background

Children’s formulations containing ibuprofen are frequently used to treat pain and fever. These medications, available over-the-counter, have the potential to cause adverse events if usage/safety information is not adhered to. This study aimed to investigate caregivers’ knowledge about the safe use of a commonly purchased children’s formulation containing ibuprofen.

Methods

A convenience sample of caregivers in Australia and New Zealand, who had purchased Nurofen® for Children, completed an online survey assessing their knowledge of product information and dosage instructions available on/in the product packaging.

Results

In total, 219 caregivers (mainly female 95%, mean age ± SD; 35 ± 6.82 years) completed the online survey. Responses suggest limitations in their knowledge about the active ingredients, contraindications and side effect profile associated with the product. Most respondents had a good understanding about the correct dosage to give children based on their weight and/or age, but many lacked a good understanding about the correct interval between doses and the maximum number of daily doses.

Conclusions

These findings suggest that caregivers administering ibuprofen to children have gaps in their product knowledge. Strategies to help improve caregivers’ knowledge about the safe administration of these products should be prioritised in an attempt to reduce the likelihood of children experiencing ibuprofen related adverse events. Improving caregiver knowledge to address these gaps is an important issue for all health care providers.

Implementing a non-steroidal anti-inflammatory drugs communication bundle in remote and rural pharmacies and dispensing practices

Non-steroidal anti-inflammatory drugs (NSAIDs) are associated with more emergency hospital admissions due to adverse drug reactions than any other class of medicine. One way to tackle this is to ensure that patients understand how to take their NSAIDs in the safest way possible. The aim of this project was to ensure that key safety information is given to every patient, every time an NSAID is sold or dispensed. The project started as part of the Scottish Patient Safety Programme’s Pharmacy in Primary Care Collaborative. An NSAIDs bundle was developed, tested and implemented using the Model for Improvement as a framework, including multiple Plan, Do, Study, Act cycles. The bundle, and associated improvement package, was developed during phase I of the project and tested by seven teams (five pharmacies and two dispensing practices). Phase II tested the spread of the defined improvement package across an additional five community pharmacies and eight dispensing general practitioner practices. The project has resulted in the development of a simple package to improve communication with patients about NSAIDs, which should enable patients to take NSAIDs safely. Three key safety messages were developed, typical for a care bundle approach, and simple tools were employed to ensure every patient received these three key messages every time. The project aim of 95% compliance with the NSAIDs bundle within the seven initial sites by December 2015 was achieved (when an exclusion was applied). The spread of the defined improvement package to a further 13 sites was achieved by December 2016. By December 2017, all 81 community pharmacies in National Health Service (NHS) Highland had agreed to implement the NSAIDs bundle. In June 2018, a national NSAIDs bundle, based on the NHS Highland work, was introduced in community pharmacies across Scotland. We also believe that the approach could be replicated for other high-risk medicines.
