The Effects of Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) on Blood Pressure in Patients with Hypertension

Dysregulation of blood pressure control in hypertensive patients using nonsteroidal anti-inflammatory drugs (NSAIDs) could increase morbidity, mortality, and health care costs. The aims of this research were to examine the association between NSAIDs and blood pressure in hypertensive patients, compare the effects of various NSAIDs on blood pressure, and determine if NSAIDs were associated with changes in antihypertensive therapy. This retrospective cohort study included hypertensive patients who received their first prescription for any NSAID and met the inclusion criteria. Patients included in this research received their care from the medicine practice clinics at Wishard Health Services in Indianapolis, Indiana between 1993 and 2006. Patients were followed for one year after the first prescription or 30 days after the last prescription that was dispensed, whichever was less. Patients meeting the same criteria but who were prescribed acetaminophen formed the control group. The primary outcomes were first systolic blood pressure and intensification of antihypertensive therapy. Covariates affecting blood pressure or the prescribing of NSAIDs were included in the statistical models. Propensity score matching techniques were used to balance background characteristics between comparison groups. A total of 3,928 eligible patients were prescribed NSAIDs or acetaminophen. Compared to acetaminophen, prescription for NSAID was associated with a 2 mmHg increase in systolic blood pressure (P = 0.004), and a 6 mmHg increase in those concurrently prescribed beta-adrenergic blocker (P = 0.008). Ibuprofen was associated with a 3 mmHg increase in systolic blood pressure compared to naproxen (P = 0.015), and a 5 mmHg increase compared to celecoxib (P = 0.035). Ibuprofen was associated with a higher risk of systolic blood pressure increase of ≥ 20 mmHg compared to naproxen (odds ratio, 1.57; 95% confidence interval, 1.10 to 2.25; P = 0.014). Dose effects were not observed for either ibuprofen or naproxen. There was no evidence of intensification in antihypertensive therapy in patients prescribed NSAIDs. In conclusion, NSAIDs were associated with a small increase in systolic blood pressure in hypertensive patients compared to acetaminophen. The increase in systolic blood pressure from NSAIDs did not increase the risk of intensification of antihypertensive treatment. Confirmatory studies will be needed to affirm these results.Doctor of Philosoph

What is the epidemiology of medication errors, error-related adverse events and risk factors for errors in adults managed in community care contexts? A systematic review of the international literature

No commercial use is permitted unless otherwise expressly granted.Objective To investigate the epidemiology of medication errors and error-related adverse events in adults in primary care, ambulatory care and patients’ homes. Design Systematic review. Data source Six international databases were searched for publications between 1 January 2006 and 31 December 2015. Data extraction and analysis Two researchers independently extracted data from eligible studies and assessed the quality of these using established instruments. Synthesis of data was informed by an appreciation of the medicines’ management process and the conceptual framework from the International Classification for Patient Safety. Results 60 studies met the inclusion criteria, of which 53 studies focused on medication errors, 3 on error-related adverse events and 4 on risk factors only. The prevalence of prescribing errors was reported in 46 studies: prevalence estimates ranged widely from 2% to 94%. Inappropriate prescribing was the most common type of error reported. Only one study reported the prevalence of monitoring errors, finding that incomplete therapeutic/safety laboratory-test monitoring occurred in 73% of patients. The incidence of preventable adverse drug events (ADEs) was estimated as 15/1000 person-years, the prevalence of drug–drug interaction-related adverse drug reactions as 7% and the prevalence of preventable ADE as 0.4%. A number of patient, healthcare professional and medication-related risk factors were identified, including the number of medications used by the patient, increased patient age, the number of comorbidities, use of anticoagulants, cases where more than one physician was involved in patients’ care and care being provided by family physicians/general practitioners. Conclusion A very wide variation in the medication error and error-related adverse events rates is reported in the studies, this reflecting heterogeneity in the populations studied, study designs employed and outcomes evaluated. This review has identified important limitations and discrepancies in the methodologies used and gaps in the literature on the epidemiology and outcomes of medication errors in community settings.Peer reviewe

Healthcare professionals’ consensus on prescribing errors in hospital settings in Riyadh, Saudi Arabia

Purpose: To create a consensus on definition and scenarios of prescribing errors in Saudi Arabia hospital practice.Methods: A two-round Delphi technique was used to reach a consensus on a definition and 42 scenarios of prescribing errors. Thirty-five evaluators  (healthcare professionals) were asked to indicate the extent to which they agree or disagree with the definition and scenarios of prescribing errors in a score of 1 (“total disagreement”) to 9 (“total agreement”) and were given a space to comment or modify the content of the survey.Results: The study tool was initially given to 35 evaluators of whom 31 (88.6 %) responded in the first round. In the second round only 24 (77.4 %) evaluators responded. A consensus was reached to accept the definition of prescribing error modified from a previous study conducted in the UK. Regarding the types of prescribing errors, a consensus was reached to include 34 scenarios, to exclude 5 scenarios and to include 3 scenarios depending on the individual clinical situation.Conclusion: The evaluators agreed to the definition of prescribing errors developed in the United Kingdom (UK) with minor modifications. However, some types of prescribing errors might be considered as errors in Saudi Arabia but not in the UK and vice versa. It is anticipated that this definition could be utilized in future studies, particularly in Saudi Arabia, and act as a guide for future research on prescribing errors.Keywords: Prescribing error scenario, Hospital settings, Consensus, Delphi techniqu

Pharmacy education in Saudi Arabia: A vision of the future

Background: Pharmacy education in developing countries faces many challenges. An assessment of the challenges and opportunities for the future of pharmacy education in Saudi Arabia has not been conducted. Objectives: The purpose of the study was to ascertain the views and opinions of pharmacy education stakeholders regarding the current issues challenging pharmacy education, and to discuss the future of pharmacy education in Saudi Arabia. Methods: A total of 48 participants attended a one-day meeting in October 2011, designed especially for the purpose of this study. The participants were divided into six round-table discussion sessions with eight persons in each group. Six major themes were explored in these sessions, including the need to improve pharmacy education, program educational outcomes, adoption of an integrated curriculum, the use of advanced teaching methodologies, the need to review assessment methods, and challenges and opportunities to improve pharmacy experiential training. The round-table discussion sessions were videotaped and transcribed verbatim and analyzed by two independent researchers. Results: Participants agreed that pharmacy education in the country needs improvement. Participants agreed on the need for clear, measureable, and national educational outcomes for pharmacy programs in the Kingdom. Participants raised the importance of collaboration between faculty members and departments to design and implement an integrated curriculum. They also emphasized the use of new teaching methodologies focusing on student self-learning and active learning. Assessments were discussed with a focus on the use of new tools, confidentiality of examinations, and providing feedback to students. Several points were raised regarding the opportunities to improve pharmacy experiential training, including the need for more experiential sites and qualified preceptors, addressing variations in training quality between experiential sites, the need for accreditation of experiential sites, and the use of technology to track experiential activities and assessments. Conclusion: Several challenges for improving pharmacy education in Saudi Arabia were discussed by stakeholders. To tackle these challenges facing most pharmacy schools in the Kingdom, national efforts need to be considered by involving all stakeholders

Culture of Safety among Nurses in a Tertiary Teaching Hospital in Saudi Arabia

Purpose: To assess the culture of safety among nurses in a tertiary teaching hospital in Saudi Arabia.Methods: A cross-sectional survey was conducted in King Khaled University Hospital in Riyadh, Saudi Arabia. A random sample of 492 nurses was included in the survey using a pre-validated instrument, Safety Attitudes Questionnaire (SAQ).Results: Of the questionnaires given to 492 nurses, only 418 complete ones were returned, giving a response rate of 84.9 %. Most of the participants (354, 84.7 %) were staff nurses and the majority, 112 (26.8 %), had working experience of ≥ 20 years. Job satisfaction was perceived as the most common dimension of culture of safety among nurse participants (92.7 ± 14.6) followed by working conditions (82.1 ± 16.6) and safety (75.5 ± 15.5) and teamwork (75.5 ± 16.7). Stress recognition (41.9 ± 25.2) and perception of management (68.1 ± 19.1) ranked as the least common dimensions of safety culture among study subjects. A significant difference in mean score was found between males and females for both working conditions (p = 0.035) and teamwork (p = 0.045). Significant differences were also observed in terms of job satisfaction dimension scores with regard to years of work experience (p = 0.045). A significant differences was also observed in terms of stress recognition dimension scores in terms of years of work experience (p = 0.007).Conclusion: Efforts are needed from healthcare authorities to increase nurses’ perception of management and stress recognition in order to improve safety culture among nurses in Saudi Arabia.Keywords: Nurses, Safety Attitudes Questionnaire (SAQ), Safety culture, Working conditions, Teamwork, Job satisfactio

Design Qualitative semi-structured interviews were conducted. Interviews were audio-recorded then transcribed into Microsoft Word. The transcribed interviews were then imported into the qualitative analysis software NVivo where thematic analysis was applied. Thematic synthesis was achieved by coding and developing subthemes/themes from the findings of the interviews. Setting Five healthcare centres in Najran, Saudi Arabia. Participants 25 adult patients with diabetes and/or cardiovascular diseases. Results The study cohort included 16 males and nine females with a median age of 61.8 years (40 – 85 years). Diabetes was the main condition encountered among 23 patients and cardiovascular diseases were reported among 18 patients. Perceived factors leading to medicine related problems were of four types and related to: patient-, healthcare system-, clinical (condition-), and medicine-related factors. Patient-related factors were related to living situation, religious practices, diet/exercise and patients’ behaviour towards the condition and medicines. Healthcare system related factors comprised sources and availability of medicines, ease of access to healthcare system, and patient satisfaction with healthcare providers. Clinical (condition-) related factors associated with both the knowledge and control over condition, and effects of the condition among medicines intake. Medicine-related factors included lack of knowledge about medicines and medicine use. Conclusions The results of this study uncovered many factors associated with medicine related problems among cardiovascular and diabetic patients in Saudi Arabia, especially in reference to lifestyle and medicine use. Improving communication with healthcare professional alongside the introduction of national clinical guidance would mitigate the unwanted health complications related to medicine use.Peer reviewedFinal Published versio

Perceptions of thalassemia and its treatment among Malaysian thalassemia patients: A qualitative study

Background Thalassemia is a common public health problem in Malaysia and one of the most common chronic and genetic disorders. Aims The present qualitative study explores knowledge about thalassemia, perceptions about conventional therapies and the points that affect Malaysian patients with thalassemia in taking medications correctly. Methods This study used a qualitative method. Purposive and theoretical samplings were combined to explore the issues related to thalassaemia and its perceptions. Twenty-one patients with thalassemia were recruited from the Thalassemia Society, Kedah, Malaysia from July to October 2015. The semi-structured interviews were audio taped, transcribed verbatim and translated into English for thematic content analysis. Results Participants perceived thalassemia as an incurable disease which is due to genetic and blood related disorders. A positive perception was shown towards conventional therapies considering it as effective for their condition. High treatment cost was given as a reason why patients perceived conventional therapies as effective. Fear of side effects was the main reason the patients gave for their delay in looking for treatment. However, due to limited treatment options, patients were reported to show positive attitude towards the side effects due to thalassemia treatment. Conclusion This explanatory investigation suggests that thalassemia patients’ understanding about thalassemia is complex in nature. The findings may help healthcare providers remove myths about the fear of the treatment. It may also help in improving patient’s compliance towards the thalassemia therapies. Main focus for future research should be on those patients who declined the conventional therapies

A cross sectional assessment of health related quality of life among patients with Hepatitis-B in Pakistan

OBJECTIVE: The study aims to assess Health Related Quality of Life (HRQoL) among Hepatitis B (HB) patients and to identify significant predictors of the HRQoL in HB patients of Quetta, Pakistan. METHODS: A cross sectional study by adopting European Quality of Life scale (EQ-5D) for the assessment of HRQoL was conducted. All registered HB patients attending two public hospitals in Quetta, Pakistan were approached for study. Descriptive statistics were used to describe demographic and disease related characteristics of the patients. HRQoL was scored using values adapted from the United Kingdom general population survey. EQ-5D scale scores were compared with Mann–Whitney and Kruskal-Wallis test. Standard multiple regression analysis was performed to identify predictors of HRQoL. All analyses were performed using SPSS v 16.0. RESULTS: Three hundred and ninety HB patients were enrolled in the study. Majority of the participants (n = 126, 32.3%) were categorized in the age group of 18-27 years (36.07 ± 9.23). HRQoL was measured as poor in the current study patients (0.3498 ± 0.31785). The multivariate analysis revealed a significant model (F(10, 380) = 40.04, P < 0.001, adjusted r(2) = 0.401). Educational level (β = 0.399, p = 0.025) emerged as a positive predictor of HRQoL. Age, gender, occupation, income and locality were not predictive of better quality of life in HB patients. CONCLUSIONS: Hepatitis B has an adverse affect on patients’ well-being and over all HRQoL. The study findings implicate the need of health promotion among HB patients. Improving the educational status and imparting disease related information for the local population can results in better control and management of HB

Investigating the epidemiology of medication errors and error-related adverse drug events (ADEs) in primary care, ambulatory care and home settings:a systematic review protocol

INTRODUCTION: There is a need to better understand the epidemiology of medication errors and error-related adverse events in community care contexts. METHODS AND ANALYSIS: We will systematically search the following databases: Cumulative Index to Nursing and Allied Health Literature (CINAHL), EMBASE, Eastern Mediterranean Regional Office of the WHO (EMRO), MEDLINE, PsycINFO and Web of Science. In addition, we will search Google Scholar and contact an international panel of experts to search for unpublished and in progress work. The searches will cover the time period January 1990–December 2015 and will yield data on the incidence or prevalence of and risk factors for medication errors and error-related adverse drug events in adults living in community settings (ie, primary care, ambulatory and home). Study quality will be assessed using the Critical Appraisal Skills Program quality assessment tool for cohort and case–control studies, and cross-sectional studies will be assessed using the Joanna Briggs Institute Critical Appraisal Checklist for Descriptive Studies. Meta-analyses will be undertaken using random-effects modelling using STATA (V.14) statistical software. ETHICS AND DISSEMINATION: This protocol will be registered with PROSPERO, an international prospective register of systematic reviews, and the systematic review will be reported in the peer-reviewed literature using Preferred Reporting Items for Systematic Reviews and Meta-Analyses

Relevance of pharmacoepidemiology to Nepal

Drug-related problems such as overuse of injectable drug products and antimicrobials, increased cost of drug therapy, polypharmacy, and adverse drug reactions (ADRs) are prevalent in the healthcare settings of Nepal. To date, no new drug development processes or clinical trials have been conducted in Nepal, despite the fact that studies of real life situations are an essential tool for monitoring medicine use. Pharmacoepidemiology (PE) is an important area that evaluates the effects of drug use in large populations.Data obtained from pharmacoepidemiological studies may highlight ways to reduce certain drug-related problems and provide reliable information on the safety profile of a drug. Moreover, clinicians and regulatory authorities may also use the data to make drug therapy decisions, drug regulation and policy development. Therefore, there is a great need to conduct appropriate pharmacoepidemiological studies that involve multiple regions and in various groups of the population of Nepal, to collect unbiased and reliable information on drug use
