The use of social media among Saudi residents for medicines related information

This study aimed to measure the use of social media applications for health information among residents in Saudi Arabia. A cross sectional study was adopted in this study between 20th of September to 1st of December 2017. A pre-validated questionnaire was either distributed through face to face to respondents in public areas or through online survey which was posted to main social media groups in Saudi Arabia. All data was analyzed through using SPSS version 22.0. All p-values of less than 0.05 were considered significant. A total of 751 valid responses were obtained out of 1200 invitations. WhatsApp was the main application frequently used among our respondents 83.8%. In addition, about 18% of respondents use social media to search on medicines related information on weekly basis. On the other hand, 12.6% of respondents receive medical related information on social media daily. Friends are the main source of medical related information on social media which is represented by 28.5% of responses. Whereas health specialists represent only 20.1% of health information on social media. One-third of our respondents either search or receive medical related information on social media on daily and weekly basis. More than 90% of respondents prefer to receive medical related information from trusted official sources. Health authorities have to frequently review the health information contents available in social media as well as educate patients on the importance of validating the medical information available on social media from their healthcare providers.     

The impact of using pictorial aids in caregivers’ understanding of patient information leaflets of pediatric pain medications: A quasi-experimental study

IntroductionPatient information leaflets (PILs) are one of the main sources of information for over-the-counter medications (OTCs). This study aimed to assess caregivers'' understanding of instructions in PILs provided with paracetamol medications and the impact of pictograms use.MethodsA quasi-experimental study was conducted among caregivers of children aged < 13 years recruited in pediatric outpatient clinics at University Medical City in Riyadh. The calculated sample size was 128; at least 64 participants were needed in each group (the text-only group and the text-plus pictograms group). Caregivers'' health literacy was assessed using a validated Arabic version of the Newest Vital Sign scale. Participants’ understanding of PILs instructions was assessed using eight questions on the route of administration, minimal hours between doses, max daily dose, shake medication before use, storage, and reporting adverse events; and was rated based on the number of questions correctly understood. Characteristics of participants were compared by Pearson X² and t-test was used to assess the significance of mean score differences between groups.ResultsA total of 130 caregivers participated in the study; almost half of them were mothers (47%, [n = 61]) and 43% (n = 56) have “a possibility of limited health literacy”. The mean number of correct answers to questions assessing the understanding of PILs instructions was significantly higher among the text-plus pictograms group compared to the text-only group (5.25 ± 1.85 vs. 4.38 ± 1.27; p < 0.001). When results were controlled for age and gender, better health literacy was found to be associated with a better understanding of instructions (B = 0.39, 95 %CI 0.23–0.54).ConclusionLimited comprehension of medications instructions was observed; adding pictorial aids to PILs might enhance the comprehension. Differences in health literacy levels of caregivers should be considered when designing PILs.     

Use,attitudes and knowledge of medications among pregnant women: A Saudi study

Objective

Medication use during pregnancy is a major concern for most women. The aim of the present study was to assess medication use, knowledge and beliefs about medications among pregnant women in Saudi Arabia.

Methods

More than 760 pregnant women, attending the obstetric clinic, filled a semi-structured questionnaire. Data were collected about their sociodemographic background, medication use during pregnancy, medication/pregnancy risk awareness, sources of drug information and beliefs about medications.

Results

Most women had a positive attitude toward medications in general but they believed pregnant women should be more cautious regarding drug-use during pregnancy. A significant association was found between participants’ education and occupation, and beliefs about medications. In this context, well educated women and those working in a health-related career demonstrated more correct beliefs about medications. Women with health-related occupations were more knowledgeable about the life saving effect of drugs on unborn children. Women indicated inadequate provision of drug-related information from physician and pharmacist; they rely on medication pamphlet to get such information. The most frequently used drugs were paracetamol and vitamins (13.2%). Most pregnant women (59.2%) were able to identify drugs to-be avoided in pregnancy that agreed roughly with FDA categories with 23 hits out of 32. They indicated that newborn anomalies (6.5%) were not attributed to drug-use during pregnancy.

Conclusion

During pregnancy, women were more conservative and skeptic toward medication, health-care professionals should be aware of such attitudes when advising pregnant women to take medication.     

Knowledge about COVID-19 and beliefs about and use of herbal products during the COVID-19 pandemic: A cross-sectional study in Saudi Arabia

The lack of treatment options for COVID-19 has raised many concerns among populations worldwide, which has led to many attempts to find alternative options to prevent the transmission of the disease or to alleviate the progression of the infection, including focusing more on preventive measures (to prevent transmission to other individuals) and the use of natural products and herbal extracts to increase immunity and decrease the probability of getting infected. This study explored the knowledge of the population of the Kingdom of Saudi Arabia (KSA) about COVID-19 preventive measures and their belief about the consumption of herbal products for the prevention of COVID-19 infection. A total of 5,258 individuals participated in this study. Participants’ knowledge about the appropriate COVID-19 preventive measures in terms of handwashing procedures, self-quarantine and social distancing was moderate, with a mean score of 5.5 (SD: 1.7) out of 10 (representing around 55.0% of the total score). About 22.1% (n = 1,161) of the participants reported that they have used herbal products or nutritional supplements during the pandemic period, to protect themselves from the disease. Social media and the Internet (39.4%, n = 372) were the main motivators for the participants to try herbal products. Vitamin C was the most commonly used food supplement to increase immunity and reduces the chance of contracting COVID-19. Our study demonstrated that the general population in Saudi Arabia has a moderate level of knowledge about COVID-19 transmission and preventive measures. A considerable proportion of the population reported the use of herbal products or food supplements in order to protect themselves from the disease. Policymakers are suggested to provide further educational campaigns that increase population knowledge about the disease transmission routes and preventive measures. In addition, the use of herbal products should be evidence-based to ensure patient safety.     

Desire for information about drugs: relationships with patients'' characteristics and adverse effects

Introduction: Adverse effects of drugs are known to cause problems both in hospital and general practice settings, contributing to longer stays in a hospital, and increased costs of hospitalisation. By developing both a greater understanding of adverse drug reactions and effects and developing ways to reduce them will assist pharmacists in managing medicines more effectively. The aim of this study was to explore the relationships between patient characteristics, information requirements and perceptions about adverse drug effects to assist pharmacists in identifying patients most at risk of ADRs. Methods: The study took place on medical wards at a London teaching hospital during an eight week period in Autumn 2000. Patients were recruited using convenience sampling during the recruitment period. Once eligible patients consented to take part, standardised interviews were conducted at their bedside. The interviews included the use of the previously validated scale which measures the extent of information desired (EID), patient characteristics including age, gender, socioeconomic status etc and the presence of an adverse drug effect was assessed using the Naranjo algorithm. Patients were also asked semistructured questions to explore past and present experiences of adverse drug effects.Results: 82 patients were recruited, 80 were eligible for adverse effects of drugs assessment. Fifteen percent (12/80) of patients were assessed as having "definite" and "probable" adverse drug effects, based on the Naranjo algorithm. The previously validated EID scale was found to be both valid and reliable in this patient sample. There was an association between high scores on the EID scale and the presence of an adverse drug effect (chisquared = 4.97, p = 0.02). Conclusion: The results show an association between the occurrence of an adverse drug effect on admission (identified by the Naranjo scale), the experience of an adverse drug effect in the past and a patient's desire for information. The EIDscale could be developed into a useful tool for assessing and addressing patients' drug information needs for pharmacists to use when assessing adverse drug effects in everyday practice.     

Development of written information for antiretroviral therapy: comprehension in a Tanzanian population

Objective To design and develop a simple, easily readable patient information leaflet (PIL) for a commonly used antiretroviral (ARV) regimen and to evaluate its readability and acceptability in a Tanzanian population. Method A PIL incorporating simple text and pictograms was designed for the antiretroviral regimen of stavudine, lamivudine and efavirenz. The PIL was designed according to established good design guidelines, modified during a multi-stage iterative testing process and piloted in a South African Xhosa population. The PIL was made available in both English and Kiswahili. Sixty Tanzanian participants who were not taking ARVs were interviewed. They were asked to read the PIL in the language of their choice and were then asked a series of two-part questions; the first part required participants to locate the information in the PIL, after which they were asked to explain the information in their own words. Acceptability was assessed through close-ended questions and open-ended feedback. The influence of selected patient characteristics on comprehension of the PIL was investigated using one-way ANOVA and t-tests for independent samples with a significance level set at 0.05. Main outcome measure Comprehension of the written information in an overall percentage understanding. Results The overall average percentage comprehension of the PIL was 95%. The target set by the EC guideline that at least 80% of participants correctly locate and understand the information was achieved for 19 of the 20 questions. Five of the six instructions illustrated by pictograms were correctly understood by all participants. The only patient characteristics significantly associated with comprehension were educational level and self-reported ease of reading the PIL. Acceptability of the PIL was high and positive comments were associated with simplicity, good design, easy readability and user-friendliness, the latter enhanced by the inclusion of pictograms. Conclusion The PIL designed for this study was shown to be effective in communicating information about ARVs. Patient characteristics must be taken into account when developing written information, and the final document must be tested for comprehension in the target population.     

Measuring the impact of medicines information services on patient care: methodological considerations

Introduction: Medicines information services (MISs) aim to promote the safe, effective and economic use of medicines. Results from published studies suggest that they provide effective information, which in many cases results in improved patient outcome. However, there are several methodological issues that are important in the interpretation of such studies.Aim: To address methodological issues in the evaluation of MISsObjectives: To carry out a critical appraisal of papers assessing the impact on patient outcome of passive information given to health care professionals, to identify the key methodological issues and to make recommendations for future research in Europe. Methods: Literature search to identify relevant papers meeting the inclusion criteria, critical evaluation of the methods usedResults: Most studies have been conducted in the United States. Various methodological considerations were identified: study design, sampling, data collection, choice of outcome measures, and validity. The results of each study are interpreted in view of the methods used. In addition, the implications of the methods selected on the validity, reliability and generalisability of the results are discussed. Finally, suggestions for future studies are provided, in order to maximise validity and reliability.     

Clozapine serum levels and side effects during steady state treatment of schizophrenic patients: a cross-sectional study

Serum clozapine (S-Cloza) and serum desmethyl-clozapine concentrations (S-Descloza) were measured in 30 chronic schizophrenic in- and outpatients on a variable dose regimen. All patients were in steady state with respect to clozapine therapy and in a stable condition with respect to psychotic illness. The 24-h clozapine dose (median with interquartile range in parenthesis) was 350 (228–425) mg/24 h (range 100–700). There was a weak positive correlation between doses and the BPRS total score (r=0.44,P<0.05). The median S-Cloza was 1076 (706–1882) nmol/l (range 196–5581 corresponding to 64–1824 ng/ml). The S-Cloza was linearly correlated to dose but with a high interindividual variation at equal doses, e.g. a factor of 8 at 400 mg/24 h, but a low intraindividual variability of 20%. The S-Descloza averaged 77% of the S-Cloza and was highly correlated to S-Cloza (r=0.90;P<0.001). The S-Descloza/dose ratio increased with age and duration of treatment. The side effects registered were EEG abnormalities (83%), tachycardia (23%), increased liver enzyme activity (60%), orthostatic hypotension (17%), and moderate leucocytosis (17%). Only EEG changes were correlated to S-Cloza (r=0.43;P<0.05). The score values of the UKU Side Effect Scale were weakly (r=0.36) correlated to S-Cloza. No side effects were correlated to S-Descloza, doses, or treatment duration. The frequency of side effects was higher than in studies using lower mean doses indicating a correlation between doses or S-Cloza and the frequency of side effects. It is concluded that clozapine fulfils the criteria for therapeutic drug monitoring. TDM may contribute to finding the lowest effective dose with the fewest possible side effects.     

Effect of cytochrome CYP2C19 metabolizing activity on antidepressant response and side effects: Meta-analysis of data from genome-wide association studies

Cytochrome (CYP) P450 enzymes have a primary role in antidepressant metabolism and variants in these polymorphic genes are targets for pharmacogenetic investigation. This is the first meta-analysis to investigate how CYP2C19 polymorphisms predict citalopram/escitalopram efficacy and side effects.CYP2C19 metabolic phenotypes comprise poor metabolizers (PM), intermediate and intermediate+ metabolizers (IM; IM+), extensive and extensive+ metabolizers (EM [wild type]; EM+) and ultra-rapid metabolizers (UM) defined by the two most common CYP2C19 functional polymorphisms (rs4244285 and rs12248560) in Caucasians. These polymorphisms were genotyped or imputed from genome-wide data in four samples treated with citalopram or escitalopram (GENDEP, STAR*D, GenPod, PGRN-AMPS). Treatment efficacy was assessed by standardized percentage symptom improvement and by remission. Side effect data were available at weeks 2–4, 6 and 9 in three samples. A fixed-effects meta-analysis was performed using EM as the reference group.Analysis of 2558 patients for efficacy and 2037 patients for side effects showed that PMs had higher symptom improvement (SMD?=?0.43, CI?=?0.19–0.66) and higher remission rates (OR?=?1.55, CI?=?1.23–1.96) compared to EMs. At weeks 2–4, PMs showed higher risk of gastro-intestinal (OR?=?1.26, CI?=?1.08–1.47), neurological (OR?=?1.28, CI?=?1.07–1.53) and sexual side effects (OR?=?1.52, CI?=?1.23–1.87; week 6 values were similar). No difference was seen at week 9 or in total side effect burden. PMs did not have higher risk of dropout at week 4 compared to EMs. Antidepressant dose was not different among CYP2C19 groups.CYP2C19 polymorphisms may provide helpful information for guiding citalopram/escitalopram treatment, despite PMs being relatively rare among Caucasians (～2%).     

Medication errors: the role of the patient

1. Patients and their carers will usually be the first to notice any observable problems resulting from medication errors. They will probably be unable to distinguish between medication errors, adverse drug reactions, or 'side effects'.
2. Little is known about how patients understand drug related problems or how they make attributions of adverse effects. Some research suggests that patients' cognitive models of adverse drug reactions bear a close relationship to models of illness perception.
3. Attributions of adverse drug reactions are related to people's previous experiences and to their level of education. The evidence suggests that on the whole patients' reports of adverse drug reactions are accurate. However, patients do not report all the problems they perceive and are more likely to report those that they do perceive as severe. Patients may not report problems attributed to their medications if they are fearful of doctors' reactions. Doctors may respond inappropriately to patients' concerns, for example by ignoring them. Some authors have proposed the use of a symptom checklist to elicit patients' reports of suspected adverse drug reactions.
4. Many patients want information about adverse drug effects, and the challenge for the professional is to judge how much information to provide and the best way of doing so. Professionals' inappropriate emphasis on adherence may be dangerous when a medication error has occurred.
5. Recent NICE guidelines recommend that professionals should ask patients if they have any concerns about their medicines, and this approach is likely to yield information conducive to the identification of medication errors.     

Self-reported and the actual involvement of community pharmacy professionals in the management of acute childhood diarrhea in Jazan Province,Saudi Arabia: Simulated patient visits and survey study

BackgroundAcute childhood diarrhea is one of the most common causes of dehydration, and if severe, can potentially lead to death as well. The present study was aimed at evaluating the knowledge and attitudes of community pharmacy professionals towards the management of acute childhood diarrhea and comparing them with their actual practices in Jazan Province, Kingdom of Saudi Arabia (K.S.A).MethodsSimulated patient visits and a cross-sectional survey making use of a 27-item self-report questionnaire were conducted amongst a sample of 303 community pharmacy professionals (51.2 % male and 48.8 % female) with an age range of 25–56 years, between August 1 and December 1, 2021, in Jazan Province, Saudi Arabia. Convenience sampling technique was used for the recruitment of the participants.ResultsSignificant positive correlations were seen between knowledge score (self-report survey) and practice score (simulated patient visit) regarding patients’ history taking (r = 0.65; p < 0.01), drug recommendations (r = 0.71; p < 0.01) and providing information regarding food and fluid intake (r = 0.44; p < 0.01). The alpha coefficients for all the items of the survey instrument were noted to be greater than (or) equal to the 0.70 threshold for almost all sections, hence indicating good reliability and internal consistency of the developed scale.ConclusionIn the present study, even though we observed improved participants’ performance during the self report survey, their performance level greatly dropped in actual practice. This warrants for a need for educational programs to improve their actual dispensing practices. The present study has also shown simulated patient visits to be a reliable, simple and a robust method of assessing the actual dispensing practices of community pharmacy professionals.     

Measurement of antipsychotic-induced side effects: support for the validity of a self-report (LUNSERS) versus structured interview (UKU) approach to measurement

A self-report measure of antipsychotic side effects (LUNSERS) was compared with that of an established semi-structured interview (UKU side effect rating scale). The validity and the ability of the LUNSERS to determine false positives by use of an internal 'red herring' subscale were assessed. 'Red herring' items are those which do not directly relate to known antipsychotic side effects. In an open study, 29 patients with schizophrenia and schizoaffective disorder from inpatient and outpatient settings within an Australian metropolitan mental health service were assessed for antipsychotic-induced side effects using both the LUNSERS and UKU. The LUNSERS and UKU were similar in their overall assessment of antipsychotic side effects (total score correlation of 0.58) and were correlated on a wide array of individual side effect items. Correlations between total scores and individual items were higher for those patients scoring low on the LUNSERS 'red herring' items compared with both those with high 'red herring' scores and the sample as a whole. Several LUNSERS items were identified as potentially problematic, requiring further explanation or supplementation with direct questioning. The 'red herring' scale appears to enable detection of patients that may be over-reporting symptomatology. The LUNSERS is a valuable self-report measure of antipsychotic side effects, particularly in cases where red herring scores are low.     

Key performance outcomes of patient safety curricula: root cause analysis, failure mode and effects analysis, and structured communications skills

As colleges and schools of pharmacy develop core courses related to patient safety, course-level outcomes will need to include both knowledge and performance measures. Three key performance outcomes for patient safety coursework, measured at the course level, are the ability to perform root cause analyses and healthcare failure mode effects analyses, and the ability to generate effective safety communications using structured formats such as the Situation-Background-Assessment-Recommendation (SBAR) situational briefing model. Each of these skills is widely used in patient safety work and competence in their use is essential for a pharmacist's ability to contribute as a member of a patient safety team.     

Comparison of 50- and 100-g L -tryptophan depletion and loading formulations for altering 5-HT synthesis: pharmacokinetics, side effects, and mood states

RATIONALE: Differences in 5-hydroxytryptamine (5-HT) function have been the subject of extensive research in psychiatric studies. Many studies have manipulated L -tryptophan (Trp) levels to temporarily decrease (depletion) or increase (loading) 5-HT synthesis. While most researchers have used a 100-g formulation, there has been ongoing interest in using smaller-sized formulations. OBJECTIVES: This study examined the time course of multiple plasma indicators of brain 5-HT synthesis after a 50-g depletion and loading as a comparison to the corresponding 100-g formulations that are typically used. MATERIALS AND METHODS: Plasma was collected from 112 healthy adults at seven hourly intervals after consumption of either a 50- or 100-g depletion or loading. Self-ratings of mood and somatic symptoms were completed before and after Trp manipulations. RESULTS: The primary findings were that (1) the 50- and 100-g formulations produced the expected changes in plasma indicators after both depletion (-89% and -96%, respectively) and loading (+570% and +372%, respectively); (2) the 100-g depletion showed more robust effects at the 4, 5, and 6 h measurements than the 50-g depletion; (3) there was significant attrition after both the 100-g depletion and loading, but not after either of the 50-g formulations; and (4) both the 50- and 100-g depletions produced increases in negative self-ratings of mood and somatic symptoms, while loading significantly increased negative ratings after the 100 g only. CONCLUSIONS: There are important considerations when choosing among formulation sizes for use in Trp manipulation studies, and the complete 7-h time-course data set of the typical plasma Trp measures presented here may help researchers decide which methodology best suits their needs.
