A cross-sectional study was carried out using a semi-structured questionnaire administered to nurses, pharmacists and physicians at the University College Hospital of Ibadan, Nigeria. Data were analysed with descriptive and inferential statistics. Most of the study participants, 444 (55.5%) and 472 (59.0%) had excellent attitudes and perceptions of medication errors, respectively. Most of the healthcare practitioners (89.1% nurses, 71.8% pharmacists and 66.7% physicians) disagreed with the statement that medication errors are unavoidable and are merely expected daily mistakes. It was observed that 35.5%, 37.6% and 66.7% of the nurses and pharmacists, and physicians, respectively, agreed with the statement that persons responsible for medication errors should be liable for legal actions. Suggestions made by the healthcare professionals on measures to prevent medication errors included recruitment of new staff to increase staff strength (32.8%), training on medication errors (21.4%) and legible handwriting of prescribers (9.4%). The prevalence of unreported medication errors by the study participants was 24.9%. Reasons for not reporting medication error committed included that it was trivial and had no adverse effect on the patient (32.3%), excess workload (26.9%) and fear of reprimand (17.7%). The healthcare professionals displayed excellent attitudes and perceptions of medication errors. An increase in staff strength and training on medication errors were major measures suggested by the study participants to prevent medication errors.","PeriodicalId":53358,"journal":{"name":"Malaysian Journal of Pharmaceutical Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49567335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Only information on daily deaths were collected for the purpose of this study. A total of 471 COVID-19 deaths reported in Malaysia in 2020. Number of deaths reported for the age categories < 65 years old and ≥ 65 years old were almost equal. Majority of deaths were reported among male (66.2%), Malaysian (82.8%), from the state of Sabah (56.3%) and with comorbidities (75.4%). Commonly reported comorbidities were hypertension (53.1%), diabetes mellitus (37.6%) and heart disease (17.4%).

Curcumin is commonly known as turmeric and it gains the interest of scientific and clinical researchers as it exhibits great pharmacological benefits such as anti-cancer, antiinflammatory and anti-oxidant properties. Nevertheless, curcumin is still not an approved drug in clinical settings due to its poor aqueous solubility and low oral bioavailability. Therefore, a self-microemulsifying drug delivery system (SMEDDS) was used as an approach to enhance the solubility and bioavailability of curcumin. The microemulsion was devised in a pre-formulation phase using a surfactant (Tween 80), a co-surfactant (polyethylene glycol, PEG 400), a lipid phase (palm oil) and an aqueous phase (water). A ternary phase diagram was used to identify the self-microemulsifying region in a formulation. Five of these formulations (F1, F2, F4, F7 and F10) were found to be stable with no phase separation observed upon overnight storage. All of the five formulations (except F4) possessed a high percentage of transmittance (86%–100%), which signified the formation of a stable microemulsion when they were diluted in a 1:100 ratio by water. Curcumin microemulsions were formulated by loading curcumin into F1, F2, F7 and F10. Only F1 and F2 curcumin microemulsions exhibit a clear appearance, however, F7 and F10 form a turbid solution, which indicates the formation of the emulsion. The results indicated that F1 and F2 which contain a high surfactant/co-surfactant-to-oil ratio of 9:1 is optimum to formulate the curcumin microemulsions.","PeriodicalId":53358,"journal":{"name":"Malaysian Journal of Pharmaceutical Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44786043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The occurrence of MEs can lead to serious clinical outcomes and represents a significant concern for healthcare providers and policymakers.

This study was conducted by reviewing ME reports at the HRPB from 1 January 2019 to 31 December 2019. A total of 1,066 ME reports were received by the Drug Information Centre (DIC) of the HRPB in 2019. However, only 1,045 reports that fulfilled the inclusion and exclusion criteria were reviewed. From these reports, 97.5% of errors were classified as near-misses. The actual error rate is only 2.5%. More than four-fifth of the overall reports originated from the wards (91.1%). The mean age of the patients exposed to MEs was 47.64 ± 24.32 years. Collectively, the geriatrics patients were the largest identified group that encountered MEs (n = 387, 37.1%). The prescribing stage accounted (97.4%) for almost all the MEs. Cases of wrong dose (52.3%) contributed to more than half of the overall error. About 99.4% of the errors had no harmful effect on the patient’s health conditions. The cardiovascular system (25.0%) was the most common drug class involved in ME. Staff factor was believed to be the principal contributing factors that lead to MEs. Majority of the MEs were detected and reported by the pharmacist. Effective implementation of proper guidelines and existing preventive strategies would help in reducing and eliminating MEs, thus improving clinical practices and ensure patients’ safety.","PeriodicalId":53358,"journal":{"name":"Malaysian Journal of Pharmaceutical Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47364178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A face validated Likert-type questionnaire was administered to assess the public perceptions and their preferences on community pharmacist attire. Four sets of model photographs with variation in gender, ethnicity and attire formality (i.e., formal wear with lab coat to casual attire) were used to assess respondents’ preferences. The most preferred attire of pharmacists was formal wear with a lab coat compared to other styles of attire (74% versus 36%). The older the respondents were, the more likely they prefer pharmacists in the formal wear with lab coat attire compared to formal (OR: 0.943; 95% CI: 0.899, 0.989; p < 0.05) and semi-formal wear (OR: 0.912; 95% CI: 0.840, 0.989; p < 0.05).

Although different anti-diabetic agents are available to control blood glucose, patient self-management is essential for achieving good glycaemic control. Good knowledge of disease self-management is a pre-requisite to enable patients in making informed decisions in disease management. In this study, we aimed to determine the knowledge of self-management among patients with T2DM visiting outpatient pharmacy at Hospital Taiping. Adult patients with T2DM were invited to participate in a survey from December 2018 to February 2019. A pre-validated, selfadministered questionnaire was used to capture patients’ demographics, glucose level and diabetes self-management knowledge. A total of 148 patients responded to the survey. More than half of the patients (54.7%) in this study were found to have low knowledge scores (< 70%). The level of education (p = 0.041), occupation (p = 0.024) and the use of insulin (p < 0.001) were significantly associated with patients’ level of self-management knowledge whereas no significant relationships were found between knowledge score across age, gender, ethnicity, living status, use of oral anti-diabetic agents, attending diabetes education before and the duration of diabetes. A low but significant negative correlation was found between the score of self-management knowledge and fasting blood glucose (r = −0.264, p = 0.002).
