Healthcare professionals' willingness to utilize a mobile health application for adverse drug reaction reporting in a limited resource setting: An input for digital health, 2023. Eur J Obstet Gynecol Reprod Biol X 2024; 23:100324. [PMID: 39050924 PMCID: PMC11268114 DOI: 10.1016/j.eurox.2024.100324] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2024] [Revised: 06/15/2024] [Accepted: 06/27/2024] [Indexed: 07/27/2024] Open
Abstract
Background Adverse drug reactions (ADRs) are a significant public health concern, particularly in limited resource settings where underreporting is prevalent due to various challenges. Mobile health applications (mHealth apps) offer a promising solution to enhance pharmacovigilance by facilitating easier and more efficient ADR reporting. However, despite the increasing availability and use of mHealth apps, there is a lack of evidence on healthcare professionals' willingness to adopt them for ADR reporting in resource-constrained environments. Therefore, this study aimed to assess the willingness of healthcare professionals in Ethiopia to utilize mobile health applications for adverse drug reaction reporting and identify associated factors. Methods We carried out a cross-sectional study involving 422 healthcare professionals working in institutional settings. We gathered data through a pretested questionnaire that participants completed themselves. We inputted the data using Epi Data V.4.6 and analyzed it using SPSS V.26. Our analysis involved conducting multivariable logistic regression to identify the factors influencing the likelihood of healthcare professionals using mobile applications to report adverse drug reactions. Results The study involved 389 healthcare professionals. Approximately 301 (77.4 %) of them expressed willingness to utilize mobile applications for reporting adverse drug reactions. The willingness to utilize mobile applications was significantly associated with the type of mobile phone (smart: AOR 3.56; 95 % CI 2.15-5.67), basic computer training (AOR 4.43; 95 % CI 2.27-8.64), mobile health-related training (AOR 1.96; 95 % CI 1.01-3.79), attitude (AOR 4.01; 95 % CI 2.19-7.35), perceived ease of use (AOR 2.91; 95 % CI 1.59-5.23), and perceived usefulness (AOR 2.10; 95 % CI 1.15-3.85). Conclusions Overall, there was a high proportion of healthcare professionals willing to use mobile devices for reporting drug adverse reactions. Their willingness correlated with factors such as the type of mobile phone, perceived ease of use, attitude, training, and perceived usefulness of mobile applications. With the increasing use of smartphones, motivation among healthcare professionals is rising. Basic computer and mHealth-related training are crucial for enhancing the acceptability of such applications and should be incorporated into future implementations. Taking these factors into account could offer insights into the design and implementation of mobile applications for adverse drug reactions in Ethiopia.

Abstract
Objectives: This study aimed to describe the prevalence and characteristics of ADRs and to identify the factors associated with ADRs among hospitalized patients. Methodology: A descriptive cross-sectional study was conducted over a 6 month period at Teaching Hospital Karapitiya (THK), Sri Lanka. A total of 2000 patients, who were admitted consecutively for any type of treatment during the study period were enrolled. The factors associated with ADRs were evaluated using logistic regression models, using ADR occurrence as the outcome. Results: A total of 123 ADRs were found from the sample. The prevalence of ADRs among hospitalized patients was 6.2%. (95% CI 5.1-7.2). ADRs were reported in 62 males (50.4%). The median (IQR) age of ADR occurrence was 52 (35-67) years. The most prevalent type of ADR was Type A (n = 62, 50.4%) and out of the total ADRs, 74 were moderately severe reactions (60.2%). Antibiotics (n = 29, 23.5%) were the most common causative agent for ADRs, followed by anticoagulants (n = 10, 8.1%). The multivariate logistic regression model showed that the number of prescribed drugs (P = .011), ADR history (P = 0 0.01) and diabetes mellitus (P = .003) were significantly associated with the occurrence of ADRs. Age (P = .21), gender (P = .31), ethnicity (P = .14), and other concomitant illnesses (Hypertension P = .66, Ischemic Heart Disease P = .25, etc.) did not associated with the occurrence of ADRs. Conclusion: According to this study the prevalence of ADRs was significant among inward patients in the Teaching Hospital, Karapitiya. The number of prescribed drugs, ADR history and diabetes mellitus were significantly correlated with the occurrence of ADRs. The results of the study can be used to guide healthcare professionals to revise the medication list frequently and monitor the patients who are at risk for developing ADRs.

Abstract
INTRODUCTION Adverse drug reactions (ADRs) are common among people with dementia; however, little is known about the magnitude and predictors associated with ADR-related hospitalisation among these individuals. This study aimed to determine the magnitude, types, drugs implicated and predictors of ADRs associated with hospitalisation among people with dementia. METHODS This retrospective case-control study analysed medical records of individuals aged ≥ 65 years with dementia admitted to major public hospitals in Tasmania, Australia, from July 2010 to July 2021. Adverse drug reactions and implicated drugs were identified using administrative data and cross-checked with hospital medical records, with consensus reached among the research team. RESULTS Of the 7928 people admitted to hospital at least once within the study period, 1876 (23.7%) experienced at least one ADR-related hospitalisation. Of these, 300 case patients with 311 ADRs and 300 control patients were randomly selected. The most common types of ADRs were renal (acute kidney injury; AKI) (36.0%), followed by neuropsychiatric (17.6%), cardiovascular (16.0%) and haematological (13.1%). Diuretics, renin-angiotensin system (RAS) inhibitors and anti-thrombotics constituted the main implicated drug classes. The ADR-related hospitalisation was associated with: chronic kidney disease (CKD) (OR 8.00, 95% CI 2.63-24.28, p < 0.001), Australian-born (OR 1.62, 95% CI 1.08-2.43, p = 0.019), hypertension (OR 1.48, 95% CI 1.01-2.17, p = 0.044) and the number of medicines (OR 1.06, 95% CI 1.00-1.12, p = 0.022). Potentially inappropriate medication use and anticholinergic burden did not predict ADR-related hospitalisation. CONCLUSIONS These predictors could help identify the individuals at the highest risk and enable targeted interventions to be designed.

Sci Rep 2024; 14:16821. [PMID: 39039143 PMCID: PMC11263357 DOI: 10.1038/s41598-024-67263-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2023] [Accepted: 07/09/2024] [Indexed: 07/24/2024] Open
Abstract
Reporting adverse drug reactions (ADRs) is fundamental in improving medication safety. Community pharmacists (CPs) being the first point of contact for individuals seeking healthcare in a community, play a significant role in ADR reporting. However, this has been poorly implemented in many countries including Nigeria. This paper aims to explore stakeholders' perspectives on current reporting practices and suggest ways to enhance ADR reporting among CPs in Nigeria. This qualitative study employed a purposive sampling approach to identify key informants. Key informant interviews (KIIs) were conducted with 25 carefully selected pharmacists, using a semi-structured interview guide between July 2023 and August 2023. The interview transcripts were analyzed using a thematic content approach. While a low ADR reporting trend was observed among all participating pharmacists, it was notably higher among those with less than five years of experience. The main barriers to ADR reporting, as identified by the interviewed community pharmacists were lack of awareness and knowledge, absence of motivation, and insufficient feedback from National Agency for Food Drug Administration and Control (NAFDAC). Training and awareness campaigns were the most frequently suggested methods for improving ADR reporting. Other proposed strategies included providing motivation, regular feedback, establishing mandatory reporting, and simplifying the reporting process. The study has highlighted the suboptimal ADR reporting practices among CPs in Anambra state. It underscores the significance of training, sensitization, advocacy, and other related interventions as pivotal means to enhance ADR reporting in this group. Furthermore, there is a pressing need for intervention-based studies to delve into and implement these approaches effectively.

Abstract
Background Antituberculosis drugs may cause mild, moderate or severe adverse drug reactions (ADR) leading to poor compliance. Description of the pattern of ADR and their related factors can help tuberculosis (TB) control program as part of the WHO programs. This study aims to investigate the incidence of ADR and associated factors among TB patients in northern Iran. Methods This is a retrospective cohort study. The required information, including year of diagnosis, age, gender, residence area, nationality, HIV co-morbidity, history of anti TB treatment and ADR, was obtained from the Deputy of Health, Mazandaran University of Medical Sciences, Iran. All data were analyzed using SPSS version 21 software. Results Out of 3903 TB patients, 136 (3.5%) experienced major ADR. The incidence of ADR for men and women as well as for those with and without previous treatment history were 3.9% vs. 3.3% and 5.3% vs. 3.4%, respectively (p>0.05). Multiple logistic regression models showed a higher chance of ADR among those aged over 59 compared with those aged under 29 (OR=2.63, 95% confidence interval: 1.54-4.49). Conclusions Age over 59 can be considered a risk factor for ADR with anti-TB drug administration.

Abstract
OBJECTIVE To assess regional and national mortality and years of life lost (YLL) related to adverse drug events in Brazil. METHODS This is an ecological study in which death records from 2009 to 2018 from the Mortality Information System were analyzed. Codes from the International Classification of Diseases 10th revision (ICD-10) that indicated drugs as the cause of death were identified. The number of deaths and the YLL due to adverse drug events were obtained. Crude, age- and gender-specific, and age-adjusted mortality rates and YLL rates per 100,000 inhabitants were formed by year, age group, gender, and Brazilian Federative Unit. Rate ratios were calculated by comparing rates from 2009 to 2018. A joinpoint regression model was applied for temporal analysis. RESULTS For the selected ICD-10 codes, a total of 95,231 deaths and 2,843,413 YLL were recorded. Mortality rates from adverse drug events increased by a mean of 2.5% per year, and YLL rates increased by 3.7%. Increases in rates were observed in almost all age groups for both genders. Variations in rates were found between Federative Units, with the highest age-adjusted mortality and YLL rates occurring in the Distrito Federal. CONCLUSIONS The numbers and rates of deaths and YLL increased during the study period, and variations in rates of deaths and YLL were observed between Brazilian Federative Units. Information on multiple causes of death from death certificates can be useful for quantifying adverse drug events and analyzing them geographically, by age and by gender.

Abstract
Adverse drug reactions account for a substantial portion of emergency hospital admissions. However, in the last decade, few studies have been conducted to determine the prevalence of hospitalization due to adverse drug reactions. Therefore, this cross-sectional study was conducted to determine the proportion of adverse drug reactions leading to emergency hospital admission and to evaluate the risk factors for these reactions. A total of 5707 consecutive patients aged > 18 years who were emergently hospitalized due to acute medical illnesses between June 2018 and May 2021 were included. Causality assessment for adverse drug reactions was performed by using the World Health Organization-Uppsala Monitoring Centre criteria. The median patient age was 78 years (IQR 63-87), and the proportion of women was 47.9%. Among all the hospitalizations, 287 (5.0%; 95% confidence interval (CI) 4.5-5.6%) were caused by 368 adverse drug reactions. The risk factors independently associated with hospitalization due to adverse drug reactions were polypharmacy (OR 2.66), age ≥ 65 years (OR 2.00), and ambulance use (OR 1.41). Given that the population is rapidly aging worldwide, further efforts are needed to minimize hospitalizations caused by adverse drug reactions.

Abstract
BACKGROUND Overusing medication for primary headaches or other medical conditions can lead to dependency and medication-overuse headache (MOH) as an adverse drug reaction (ADR). OBJECTIVES To analyse reports of ADRs associated with MOH recorded in the French national pharmacovigilance database (FPVD). METHODS This retrospective study selected all MOH cases reported in the FPVD from January 2000 to June 2023. A search of the High-Level Group Term "headache" was performed for drugs classified under ATC codes for the musculoskeletal and nervous systems. Specific keywords were searched in report narratives to further reduce their number. Voluntary intoxication reports were excluded. Only MOH cases according to the International Classification of Headache Disorders or with a medical diagnosis of MOH were considered. RESULTS Among the 2674 reports associated with the HLGT "headache", for 649 ATC drug codes, only 234 reports correspond to MOH, primarily notified by physicians. The median age was 45 years (IQR: 32-56), with 74.4% females and approximately 61.0% having pre-existing primary headaches. In all, 53.4% of the reports were classified as serious. Among patients, 84.2% had an isolated "headache" as the ADR. One drug was suspected in 47.4% of cases, two drugs in 29.1%, and three or more in 23.5%. In total, 473 suspected drugs, corresponding to 104 active ingredients, were involved, including analgesics (63.0%), in particular, acetaminophen-containing drugs, opioids, triptans and ergots, and non-steroidal anti-inflammatory drugs (12.7%). Antiepileptics and psycholeptics were found in 6.6% and 6.1% of cases, respectively. Drug withdrawal was successful in 84.6% of drug-discontinuation cases. Warnings about MOH are mentioned in the summary of product characteristics (SmPCs) for triptans, ergots, and certain acetaminophen-containing drugs, but not other drug classes. CONCLUSIONS Certain drug classes show a high reporting rate of MOH and caution should be exercised when prescribing these drugs. Notably, warnings about MOH must be mentioned in the SmPC of all concerned drug classes.

Abstract
BACKGROUND This study aimed to determine the clinical impact associated with adverse drug reactions (ADRs) in patients with dementia. RESEARCH DESIGN AND METHODS This case-control, propensity score-matched study utilized administrative data of people with dementia admitted to major public hospitals in Tasmania, Australia, from July 2010 to December 2019. RESULTS Acute renal failure constituted the most common ADR. The length of hospital stay was greater for people with an ADR index admission, versus non-ADR index admission (median [IQR]: 9 [4-18] versus 6 [2-12]; p < 0.001). In-hospital mortality and combined in-hospital and post-hospital mortality within 30, 60 and 90 days were higher for those whose index admission was ADR-related (in-hospital: HR 1.40, 95% CI 1.11-1.77, p-value <0.001; 30 days: HR 1.25, 95% CI 1.05-1.49, p-value <0.001; 60 days: HR 1.27, 95% CI 1.08-1.49, p-value <0.001; 90 days: HR 1.29, 95% CI 1.10-1.50, p-value <0.001). Subsequent ADR admission within 30, 60 and 90 days of index discharge was 9 to 10 times greater for people with dementia (30 days: OR 10.0, 95% CI 6.04-16.8, p-value <0.001; 60 days: OR 8.96, 95% CI 5.57-14.4, p-value <0.001; 90 days: OR 9.31, 95% CI 5.79-14.9, p-value <0.001). CONCLUSION Safe prescribing and vigilant monitoring of ADRs is pivotal to mitigate adverse outcomes in people with dementia.

Abstract
BACKGROUND Older adults are at an increased risk of drug-related problems, especially following discharge from hospital. Drug-related readmissions place a large burden on the patient and the healthcare system. However, previous studies report inconsistent results on the prevalence and associated risk factors for drug-related hospital readmissions in older adults. OBJECTIVES We aimed to assess the prevalence of drug-related readmissions in older adults aged 65 years and older and investigate the drug classes, preventability and risk factors most associated with these readmissions. METHODS A systematic review and meta-analysis were undertaken to answer our objectives. A search of four databases (MEDLINE, Embase, CINAHL and Scopus) was conducted. Three authors independently performed title and abstract screening, full-text screening and data extraction of all included studies. A meta-analysis was conducted to calculate the pooled prevalence of drug-related readmissions across all studies, and a subgroup analysis was performed to explore heterogeneity among studies reporting on adverse drug reaction-related readmissions. RESULTS A total of 1978 studies were identified in the initial search, of which four studies were included in the final synthesis. Three studies focused on readmissions due to adverse drug reactions and one study focused on readmissions due to drug-related problems. A pooled prevalence of 9% (95% confidence interval 2-18) was found for drug-related readmissions across all studies, and a pooled prevalence of 6% (95% confidence interval 4-10) was found for adverse drug reaction-related readmissions. Three studies explored the preventability of readmissions and 15.4-22.2% of cases were deemed preventable. The drug classes most associated with adverse drug reaction readmissions included anticoagulants, antibiotics, psychotropics and chemotherapy agents. Polypharmacy (the use of five or more medications) and several comorbidities such as cancer, liver disease, ischaemic heart disease and peptic ulcer disease were identified as risk factors for drug-related readmissions. CONCLUSIONS Almost one in ten older adults discharged from hospital experienced a drug-related hospital readmission, with one fifth of these deemed preventable. Several comorbidities and the use of polypharmacy and high-risk drugs were identified as prominent risk factors for readmission. Further research is needed to explore possible causes of drug-related readmissions in older adults for a more guided approach to the development of effective medication management interventions.

Domingues ÍP, Costa MRD. [Update of triggers for detection of adverse drug events in hematologic patients]. CAD SAUDE PUBLICA 2023; 39:e00077923. [PMID: 38126560 PMCID: PMC10740396 DOI: 10.1590/0102-311xpt077923] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Revised: 08/10/2023] [Accepted: 08/21/2023] [Indexed: 12/23/2023] Open
Abstract
The use of triggers for the active search and detection of adverse drug events (ADEs) has been gaining ground within pharmacovigilance services. Thus, the main objective of the study was to propose a new list of triggers to be used in a center specialized in hematology in Rio de Janeiro, Brazil. The update of the list of triggers consisted of revising the current list, with the exclusion and inclusion of new triggers. To verify the performance of the new list of triggers, a cross-sectional study was conducted in which the new triggers were used to investigate the occurrence of ADEs in patients attended in the emergency unit or hospitalized from January to March 2022. For each suspected ADEs, the patient's profile and adverse drug reactions (ADRs) were characterized regarding causality and severity. The performance of the triggers and their ability to capture ADEs were estimated using the following indicators: frequency of the trigger per 100 medical records, frequency of ADEs per 100 records, and positive predictive value (PPV). To evaluate the overall performance of the proposed new list, the PPV was estimated. A total of 374 prescriptions for triggers were identified in 186 medical records. The most efficient in the detection of possible ADEs were: lidocaine, loperamide, bisacodyl, filgrastim and glycerin clyster. The overall PPV of the new suggested list was 48% versus 10% of the previous list. This study demonstrated the importance of an updated list of triggers for the monitoring of ADEs and improvement of the care provided.

Abstract
BACKGROUND Adverse drug reactions (ADR), both preventable and non-preventable, are frequent and pose a significant burden. This study aimed to produce up-to-date estimates for ADR rates in hospitals, in Portugal, from 2010 to 2018. In addition, it explores possible pitfalls when crosswalking between ICD-9-CM and ICD-10-CM code sets for ADR identification. METHODS The Portuguese Hospital Morbidity Database was used to identify hospital episodes (outpatient or inpatient) with at least one ICD code of ADR. Since the study period spanned from 2010 to 2018, both ICD-9-CM and ICD-10-CM codes based on previously published studies were used to define episodes. This was an exploratory study, and descriptive statistics were used to provide ADR rates and summarise episode features for the full period (2010-2018) as well as for the ICD-9-CM (2010-2016) and ICD -10-CM (2017-2018) eras. RESULTS Between 2010 and 2018, ADR occurred in 162,985 hospital episodes, corresponding to 1.00% of the total number of episodes during the same period. Higher rates were seen in the oldest age groups. In the same period, the mean annual rate of episodes related to ADR was 174.2/100,000 population. The episode rate (per 100,000 population) was generally higher in males, except in young adults (aged '15-20', '25-30' and '30-35' years), although the overall frequency of ADR in hospital episodes was higher in females. CONCLUSIONS Despite the ICD-10-CM transition, administrative health data in Portugal remain a feasible source for producing up-to-date estimates on ADR in hospitals. There is a need for future research to identify target recipients for preventive interventions and improve medication safety practices in Portugal.

Abstract
INTRODUCTION Adverse drug reactions (ADRs) contribute to morbidity, and serious ADRs may cause hospitalisation and death. This study characterises and quantifies ADR-related hospitalisations and subsequent in-hospital deaths, and estimates the spontaneous reporting rate to regulatory authorities in Switzerland, where healthcare professionals are legally obliged to report ADRs. METHODS This retrospective cohort study from 2012 to 2019 analysed nationwide data from the Federal Statistical Office. ICD-10 coding rules identified ADR-related hospitalisations. To estimate the reporting rate, individual case safety reports (ICSRs) collected in the Swiss spontaneous reporting system during the same period were considered. RESULTS Among 11,240,562 inpatients, 256,550 (2.3%) were admitted for ADRs, 132,320 (51.6%) were female, 120,405 (46.9%) were aged ≥ 65 (median of three comorbidities, interquartile range [IQR] 2-4), and 16,754 (6.5%) were children/teenagers (0 comorbidities, IQR 0-1). Frequent comorbidities were hypertension (89,938 [35.1%]), fluid/electrolyte disorders (54,447 [21.2%]), renal failure (45,866 [17.9%]), cardiac arrhythmias (37,906 [14.8%]), and depression (35,759 [13.9%]). Physicians initiated 113,028 (44.1%) of hospital referrals, and patients/relatives 73,494 (28.6%). Frequently ADR-affected were the digestive system (48,219 [18.8%], e.g. noninfective gastroenteritis and colitis), the genitourinary system (39,727 [15.5%], e.g. acute renal failure), and the mental/behavioural state (39,578 [15.4%], e.g. opioid dependence). In-hospital mortality was 2.2% (5669). Since ICSRs indicated 14,109 hospitalisations and 700 in-hospital deaths, estimated reporting rates were 5% and 12%, respectively. CONCLUSIONS This 8-year observation in Switzerland revealed that 2.3%, or roughly 32,000 admissions per year, were caused by ADRs. The majority of ADR-related admissions were not reported to the regulatory authorities, despite legal obligations.

Abstract
Background Adverse drug reactions (ADRs) contribute to the burden of disease globally and of particular concern are ADR-related hospital admissions. Objectives This study sought to determine the burden, characteristics, contributing factors and patient outcomes of ADRs that were the primary diagnosis linked to hospital admission among inpatients in Uganda. Design We conducted a cross-sectional secondary analysis of data from a prospective cohort study of adult inpatients aged 18 years and older at Uganda's Mulago National Referral Hospital from November 2013 to April 2014. Methods We reviewed clinical charts to identify inpatients with an ADR as one of the admitting diagnoses and, if so, whether or not the hospital admission was primarily attributed to the ADR. Logistic regression was used to determine factors associated with hospital admissions primarily attributed to ADRs. Results Among 762 inpatients, 14% had ADRs at hospital admission and 7% were primarily hospitalized due to ADRs. A total of 235 ADRs occurred among all inpatients and 57% of the ADRs were the primary diagnosis linked to hospital admission. The majority of ADRs occurred in people living with HIV and were attributed to antiretroviral drugs. HIV infection [aOR (adjusted odds ratio) = 2.97, 95% confidence interval (CI): 1.30-6.77], use of antiretroviral therapy (aOR = 5.46, 95% CI: 2.56-11.68), self-medication (aOR = 2.27, 95% CI: 1.14-4.55) and higher number of drugs used (aOR = 1.13, 95% CI: 1.01-1.26) were independently associated with hospital admissions attributed to ADRs. Conclusion Antiretroviral drugs were often implicated in ADR-related hospital admissions. HIV infection (whether managed by antiretroviral therapy or not), self-medication and high pill burden were associated with hospital admissions attributable to ADRs. The high HIV burden in Sub-Saharan Africa increases the risk of ADR-related hospitalization implying the need for emphasis on early detection, monitoring and appropriate management of ADRs associated with hospital admission in people living with HIV.

Abstract
BACKGROUND Adverse drug reactions (ADRs) are escalating, and their socioeconomic burden is increasing. However, large-scale prospective studies investigating ADRs during hospitalization are rare in Korea. We prospectively investigated the incidence, characteristics, and economic burden of ADRs in hospitalized patients based on electronic medical records (EMRs). METHODS Among patients admitted to three hospitals from October 2016 to October 2017, 5,000 patients were randomly selected and prospectively observed during hospitalization. Research nurses monitored and detected patients who had symptoms, signs, or laboratory findings suspicious for ADRs using an EMR-based detection protocol. Next, allergy and ADR specialists reviewed the medical records to determine the relationship between adverse reactions and drugs. Cases in which a causal relationship was certain, probable/likely, or possible were included in the ADR cases. Clinically meaningful ADR cases or those leading to prolonged hospitalization were defined as significant ADRs. RESULTS ADRs occurred in 510 (10.2%) patients. The mean length of hospital stay was approximately 5 days longer in patients with ADRs. Opioids accounted for the highest percentage of total ADRs. Significant ADRs were observed in 148 (3.0%) patients. Antibiotics accounted for the highest percentage of significant ADRs. Drug hypersensitivity reactions (DHRs) occurred in 88 (1.8%) patients. Antibiotics accounted for the highest percentage of DHRs. The average medical expenses for one day of hospitalization per patient were highest in significant ADRs, followed by non-significant ADRs, and non-ADRs. CONCLUSION ADRs in hospitalized patients are an important clinical issue, resulting in a substantial socioeconomic burden. EMR-based strategy could be a useful tool for ADR monitoring and early detection.

Which Adverse Events and Which Drugs Are Implicated in Drug-Related Hospital Admissions? A Systematic Review and Meta-Analysis. J Clin Med 2023; 12:jcm12041320. [PMID: 36835854 PMCID: PMC9963366 DOI: 10.3390/jcm12041320] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Revised: 01/23/2023] [Accepted: 01/30/2023] [Indexed: 02/11/2023] Open
Abstract
Adverse drug events (ADEs) and adverse drug reactions (ADRs) are leading causes of iatrogenic injury, which can result in emergency department (ED) visits or admissions to inpatient wards. The aim of this systematic review and meta-analysis was to provide up-to-date estimates of the prevalence of (preventable) drug-related ED visits and hospital admissions, as well as the type and prevalence of implicated ADRs/ADEs and drugs. A literature search of studies published between January 2012 and December 2021 was performed in PubMed, Medline, EMBASE, Cochrane Library, and Web of Science. Retrospective and prospective observational studies investigating acute admissions to EDs or inpatient wards due to ADRs or ADEs in the general population were included. Meta-analyses of prevalence rates were conducted using generalized linear mixed models (GLMM) with the random-effect method. Seventeen studies reporting ADRs and/or ADEs were eligible for inclusion. The prevalence rates of ADR- and ADE-related admissions to EDs or inpatient wards were estimated at 8.3% ([95% CI, 6.4-10.7%]) and 13.9% ([95% CI, 8.1-22.8%]), respectively, of which almost half (ADRs: 44.7% [95% CI: 28.1; 62.4]) and more than two thirds (ADEs: 71.0% [95% CI, 65.9-75.6%]) had been classified as at least possibly preventable. The ADR categories most frequently implicated in ADR-related admissions were gastrointestinal disorders, electrolyte disturbances, bleeding events, and renal and urinary disorders. Nervous system drugs were found to be the most commonly implicated drug groups, followed by cardiovascular and antithrombotic agents. Our findings demonstrate that ADR-related admissions to EDs and inpatient wards still represent a major and often preventable health care problem. In comparison to previous systematic reviews, cardiovascular and antithrombotic drugs remain common causes of drug-related admissions, while nervous system drugs appear to have become more commonly implicated. These developments may be considered in future efforts to improve medication safety in primary care.

Abstract
PURPOSE To determine the nature and frequency of duplicate prescriptions (DPs) in the emergency department (ED) by utilization of a novel categorization of DPs which differentiates between appropriate DPs (ADPs) and potentially inappropriate DPs (PIDPs). METHODS In this retrospective cohort study, adult patients who presented to the ED for internal medicine of a large university hospital in northern Germany in 2018 and 2019 were screened for the presence of DPs. Descriptive statistical methods were used to characterize the nature and frequency of PIDPs compared to the frequency of ADPs. RESULTS A total of 4208 patients were enrolled into the study. The median age of the study population was 63 years (interquartile range (IQR) 48-77), 53.9% were female. The patients took a median of 5 drugs (IQR 3-9). 10.9% of the study population were affected by at least one PIDP (at least one grade-1 PIDP: 6.1%; at least one grade-2 PIDP: 4.5%; at least one grade-3 PIDP: 1.1%). Non-opioid analgesics accounted for the majority of grade-1 PIDPs, while inhalatives were most frequently responsible for grade-2 and grade-3 PIDPs. Nearly half of the study population (48.6%) displayed at least one ADP. CONCLUSION PIDPs pose a frequent pharmacological challenge in the ED. The medication review should comprise a systematic screening for PIDPs with a particular focus on non-opioid analgesics and inhalatives. ADPs were detected more frequently than PIDPs, questioning the predominant notion in the medical literature that DPs are exclusively deleterious.

Adverse drug reactions in an ageing PopulaTion (ADAPT) study: Prevalence and risk factors associated with adverse drug reaction-related hospital admissions in older patients. Front Pharmacol 2023; 13:1029067. [PMID: 36712658 PMCID: PMC9880441 DOI: 10.3389/fphar.2022.1029067] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2022] [Accepted: 12/23/2022] [Indexed: 01/15/2023] Open
Abstract
Background: Older people experience greater morbidity with a corresponding increase in medication use resulting in a potentially higher risk of adverse drug reactions (ADRs). Objectives: The aim of this study was to; 1) determine the prevalence and characteristics of ADR-related hospital admissions among older patients (≥65 years) in Ireland; and 2) identify the risk factors associated with ADR-related hospital admissions. Methods: A cross-sectional study of ADR prevalence in patients aged ≥65 years admitted acutely to hospital in Ireland over a 8 month period (November 2016- June 2017). A multifaceted review of each hospital admission was undertaken to assess the likelihood of an ADR being a reason for admission (cause of admission or contributing to admission) in the context of the patient's medication, clinical conditions, comorbidities and investigations. A number of decision aids were applied by two independent reviewers to assess ADR causality, avoidability and severity. A random sample of patients, determined not to have a suspected ADR on screening, were assigned to a non-ADR control group. Multivariable logistic regression was used to assess the association between potential risk factors for ADR-related admissions compared with non-ADR-related admissions. Results: In total, 3,760 hospital admission episodes (in 3,091 patients) were screened and 377 admissions were considered ADR-related (10.0%, 95% CI 9.1%, 11.0%). 219 (58.1%) ADR-related admissions were caused by an ADR, while ADRs contributed to 158 (41.9%) admissions. 268 (71.1%) of all ADR-related admissions were deemed definitely or possibly preventable/avoidable. 350 (92.8%) ADRs were classified as being of moderate severity, with 27 (7.2%) classified as severe. Antithrombotic agents, mainly aspirin and warfarin, were the drugs most frequently associated with ADR-related admissions (gastrointestinal and vascular haemorrhagic disorders). In multivariable analysis, immobility, frailty, having delirium or ulcer disease and taking anticoagulant and antiplatelet medication on admission were significantly associated with an ADR-related hospital admission. Conclusion: One in ten hospital admissions, among those aged 65 + years, were considered ADR-related, with approximately 70% potentially avoidable. Reliable and validated ADR detection and prediction tools are needed to develop prevention strategies.

Abstract
INTRODUCTION Seasonal malaria chemoprevention (SMC) by mass administration of sulfadoxine pyrimethamine + amodiaquine (SPAQ) reduces the burden of malaria in children aged 3-59 months. The occurrence of adverse drug reaction (ADR) may affect the success of this intervention. There are few studies of SMC adverse event surveillance in sub-Saharan Africa, particularly in Burkina Faso, a highly endemic country. Our main objective was to characterize the ADRs reported during SMC campaigns in Burkina Faso. Secondly, we evaluated the performance of the pharmacovigilance integrated into the SMC program in order to support safe administration of SMC. METHOD This was a retrospective descriptive study of SMC individual case safety reports recorded in VigiBase® in Burkina Faso from 2014 to 2021. We used the P-method for the analysis of preventable serious adverse drug reactions and WHO criteria for assessing the performance of pharmacovigilance integrated into the SMC program. RESULTS A total of 1,105 SMC individual case safety reports were registered in VigiBase® for 23,311,453 doses of SPAQ given between 2014 and 2021. No pharmacovigilance signal was detected. The number of serious cases was 101, of which 23 (22.8%) were preventable. In 38.1% of children, the occurrence of ADRs led to discontinuation of SMC treatment. Vomiting was the most frequently reported adverse drug reaction (48.0%). The proportion of children whose treatment was discontinued due to vomiting was 42.7%, while the proportion of treatment discontinuation for other ADRs was 32.8% (p = 0.01). The SMC program contributed at 46.2% to the national pharmacovigilance database. The reporting rate was 0.03 per 1,000 exposed children in 2021. The median completeness score of the ICSRs was 0.7 (IQR: 0.5-0.7), and the median time to register the ICSRs in VigiBase® was 204 (IQR: 143-333) days. CONCLUSIONS Post-drug administration vomiting may interfere with the purpose of SMC. Measures to manage this adverse drug reaction should be taken to improve the success of the SMC program. Based on the information on reporting time and reporting rate, spontaneous reporting should be supported by active surveillance, including cohort event monitoring, in Burkina Faso.

Eur J Clin Pharmacol 2023; 79:99-116. [PMID: 36399205 DOI: 10.1007/s00228-022-03419-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2022] [Accepted: 11/05/2022] [Indexed: 11/21/2022]
Abstract
PURPOSE To estimate the risk of mortality and length of stay in hospitalised patients who have experienced suspected adverse drug reactions (ADRs) as compared to patients who did not experience suspected ADRs. METHODS A systematic literature search was conducted on databases for observational and randomised controlled studies conducted in any inpatient setting that reported deaths and/or length of hospital stay in patients who had suspected ADRs and did not have suspected ADRs during hospitalisation. PRISMA guidelines were strictly followed during the review. The methodological quality of included studies was assessed using a tool designed by Smyth et al. for the studies of adverse drug reactions. The meta-analytic summary of all-cause mortality was estimated using odds ratio-OR (95% CI) and length of stay using mean difference-MD (95% CI). Both outcomes were pooled using a random effect model (DerSimonian and Laird method). Subgroup and meta-regression were performed based on study variables: study design, age group, study ward, study region, types of suspected ADRs (ADRAd-suspected ADRs that lead to hospitalisation and ADRIn-suspected ADRs that occur following hospitalisation), study duration, sample size and study period. The statistical analysis was conducted through the 'Review manager software version 5.4.1 and JASP (Version 0.14.1)'. RESULTS After screening 475 relevant articles, 55 studies were included in this meta-analysis. Patients having suspected ADRs had reported significantly higher odds of all-cause mortality [OR: 1.50 (95% CI: 1.21-1.86; I2 = 100%) than those patients who did not have suspected ADRs during hospitalisation. Study wards, types of suspected ADRs and sample size were observed as significant predictors of all-cause mortality (p < 0.05). Patients having suspected ADRs had reported significantly higher mean difference in hospital stay [MD: 3.98 (95% CI: 2.91, 5.05; I2 = 99%) than those patients who did not have suspected ADRs during hospitalisation. Types of suspected ADRs and study periods were observed as significant predictors of length of stay (p < 0.05). CONCLUSION Suspected ADRs significantly increase the risk of mortality and length of stay in hospitalised patients. SYSTEMATIC REVIEW REGISTRATION CRD42020176320.

[PMID: 36388934 PMCID: PMC9640910 DOI: 10.3389/fmed.2022.1001876] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2022] [Accepted: 09/22/2022] [Indexed: 12/20/2023] Open
Abstract
BACKGROUND Different levels of evidence related to the variable responses of individuals to drug treatment have been reported in various pharmacogenomic (PGx) databases. Identification of gene-drug pairs with strong association evidence can be helpful in prioritizing the implementation of PGx guidelines and focusing on a gene panel. This study aimed to determine the pharmacogenes with the highest evidence-based association and to indicate their involvement in drug-gene interactions. METHODOLOGY The publicly available datasets CPIC, DPWG, and PharmGKB were selected to determine the pharmacogenes with the highest drug outcome associations. The upper two levels of evidence rated by the three scoring methods were specified (levels A-B in CPIC, 3-4 in DPWG, or 1-2 levels in PharmGKB). The identified pharmacogenes were further ranked in this study based on the number of medications they interacted with. RESULTS Fifty pharmacogenes, with high to moderately high evidence of associations with drug response alterations, with potential influence on the therapeutic and/or toxicity outcomes of 152 drugs were identified. CYP2D6, CYP2C9, CYP2C19, G6PD, HLA-B, SLCO1B1, CACNA1S, RYR1, MT-RNR1, and IFNL4 are the top 10 pharmacogenes, where each is predicted to impact patients' responses to ≥5 drugs. CONCLUSION This study identified the most important pharmacogenes based on the highest-ranked association evidence and their frequency of involvement in affecting multiple drugs. The obtained data is useful for customizing a gene panel for PGx testing. Identifying the strength of scientific evidence supporting drug-gene interactions aids drug prescribers in making the best clinical decision.

Abstract
Abstract
Objectives
Adverse drug reactions are one of the leading causes of death, yet they are under-reported. This study assessed the involvement of community pharmacists in the identification, documentation, and reporting of adverse drug reactions and pharmacy clients’ awareness of the adverse drug reaction reporting system.
Methods
A cross-sectional questionnaire-guided survey was conducted among 780 pharmacy clients in six selected community pharmacies, and seven mystery clients visited 125 community pharmacies in Ibadan, Nigeria. Information on pharmacy clients’ experience of adverse drug reactions, to whom and how they were reported, was obtained. Female and male mystery clients’ performed two scripted scenarios, complaining of black patches on their thighs and blood in their faeces, respectively. The proportion of pharmacists who identified the complaints as adverse drug reactions, documented and reported them, was described.
Key findings
The response rate for the pharmacy clients’ survey was 98.5%. Some pharmacy clients, 385 (50.1%), had experienced adverse drug reactions; 49 (12.7%) of these pharmacy clients were hospitalised and 73 (19.0%) of them reported the adverse drug reactions to physicians or pharmacists. Most of the pharmacy clients, 706 (91.9%), did not use the available reporting system. A total of 218 mystery client visits were made. The proportion of pharmacists who recognised the mystery client complaints as adverse drug reactions was 4.9–60.3% depending on the scenario presented and up to two pharmacists documented and supposedly reported the adverse drug reactions.
Conclusions
Some of the pharmacy clients reported experiencing adverse drug reactions to healthcare professionals, but most did not report through the existing reporting scheme. Community pharmacists could identify adverse drug reactions but most failed to document or report them.

Frequency, Characteristics, and Predictive Factors of Adverse Drug Events in an Adult Emergency Department according to Age: A Cross-Sectional Study. J Clin Med 2022; 11:jcm11195731. [PMID: 36233599 PMCID: PMC9572040 DOI: 10.3390/jcm11195731] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Revised: 09/22/2022] [Accepted: 09/23/2022] [Indexed: 11/18/2022] Open
Abstract
Adverse drug events (ADEs) are a major public health concern, given their consequences in terms of morbi-mortality and associated healthcare costs. Many studies have focused on the elderly, who are considered particularly vulnerable in this respect. We aimed to determine and compare the frequency, characteristics, and predictive factors of ADEs according to age in an adult population. A prospective seven-year cross-sectional study was conducted in a university hospital emergency department. Structured medication reviews and ADE detection were performed. Patient data and ADE characteristics were collected. Descriptive statistics and logistic regression were performed in two age groups: Group 1 (age < 65 years) and 2 (age ≥ 65 years). Among the 13,653 patients included, 18.4% in Group 1 and 22.6% in Group 2 experienced an ADE. Differences were identified in terms of the ADE type (more ADEs due to noncompliance in Group 1) and ADE symptoms (greater bleeding in Group 2). In the multivariable analysis, several specific predictive factors were identified, including kidney failure and antidiabetic drug use in Group 1 and inappropriate prescription and antithrombotic treatment in Group 2. Analysis by age provided a more refined vision of ADEs as we identified distinct profiles of iatrogenesis. These results will lead to a better detection of ADEs.

Abstract
Background Pharmacovigilance may be defined as the continuous monitoring of the reaction between a drug agent or combination of drugs a patient took and steps taken to prevent any associated risk. Clinical trials conducted before drug approval cannot uncover every aspect of the health hazards of approved drugs. People with carefully selected characteristics are monitored for the safety and efficacy of the drug; hence, common adverse drug reactions (ADRs) following proper use of the medication can be detected. This calls for continuous monitoring of drugs to report any undocumented ADRs during the clinical trial. The study aimed to assess the knowledge, practice, and barriers to pharmacovigilance among nurses at a teaching hospital. Methods The study was a descriptive cross-sectional study, and a stratified sampling technique was used to select 125 nurses within the three units: medical, surgical, and pediatric wards. A structured questionnaire was developed and used for data collection based on the study's objectives and reviewed literature. Results The majority (67.2%) of the respondents were females, and 32.8% were males. Most (71.2%) of the nurses had low knowledge of ADR reporting procedures. Also, 84.8% of the nurses knew the purpose of reporting ADRs. The purpose of ADR reporting, as perceived by respondents, was to identify safe drugs (80.8%) and calculate the incidence of ADR (75.2%). Additionally, among the nurses who reported having nursed a patient with ADRs, 52.54% stated they reported the case, while 47.46% did not report it. The most cited reason for not reporting ADRs was that nurses considered the reaction normal and commonly associated with that medicine (35.7%). In comparison, 28.5% of the nurses said they did not know they were supposed to report the adverse drug reaction. There was no statistically significant difference between ranks of nurses, ward, attending in-service training, and pharmacovigilance practice. Conclusion In conclusion, nurses in this study had inadequate knowledge of pharmacovigilance and its reporting procedure. The study found that most nurses fear that reporting ADRs may be wrong because most of the nurses in the study did not have any form of pharmacovigilance training.

Front Pharmacol 2022; 13:923939. [PMID: 36133826 PMCID: PMC9483724 DOI: 10.3389/fphar.2022.923939] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2022] [Accepted: 07/19/2022] [Indexed: 12/02/2022] Open
Abstract
Introduction: Adverse drug reactions (ADRs) represent a public health problem worldwide that deserves attention due to the impact on mortality, morbidity, and healthcare costs. Drug–drug interactions (DDIs) are an important contributor to ADRs. Most of the studies focused only on potential DDIs (pDDIs), while the detailed data are limited regarding the ADRs associated with actual DDIs. Methods: This retrospective study evaluated ADRs reported between 2011 and 2020 in a tertiary hospital. The causality and severity of ADRs were evaluated through the Naranjo Algorithm and Hartwig’s scale, respectively. Preventability classification was based on the modified Schoumock and Thornton scale. For ADRs with at least two suspected drugs, pDDIs were identified according to the Lexi-Interact. We further checked whether the ADR description in the reports corresponded to the clinical consequences of the pDDIs. Results: A total of 1,803 ADRs were reported, of which 36.77% ADRs were classified as mild, 43.26% as moderate, and 19.97% as severe. The assessment of causality showed that the distributions of definite, probable, and possible categories were 0.33%, 58.68%, and 40.99%, respectively. A total of 53.97% of ADRs were identified as preventable ADRs, while 46.03% were recognized as unpreventable. The severity of ADRs was significantly correlated with age, the number of suspected drugs and preventability. Antimicrobial agents were the most common implicated pharmacological group, and the most frequently affected system was the gastrointestinal system. Considering individual drugs, aspirin was the most frequently reported drug. Among 573 ADRs with at least two suspected drugs, 105 ADRs were caused by actual DDIs, of which only 59 and 6 ADRs were caused by actual DDIs in category D and X, respectively. The most frequent drugs involved in actual DDIs of category D were aspirin and heparin, with the majority of ADRs being gastrointestinal bleeding. Conclusion: This study analyzed the pattern of ADRs in detail and obtained clinical evidence about ADRs associated with actual DDIs. These findings may be useful to compare patterns between different centers and to design preventive strategies for ADRs. Continuous education and training should be provided for physicians regarding the knowledge and recognition of ADRs associated with DDIs.

Abstract
Background: Drug-related hospital admissions (DRAs) represent a significant problem affecting all countries worldwide. This study aimed to determine the prevalence and preventability of DRAs, identify the most common medications involved in DRAs, the most common clinical manifestations of DRAs and describe the preventability aspects of DRAs.Methods: This cross-sectional study examined unplanned hospital admissions to the University Hospital Hradec Králové via the department of emergency medicine in August–November 2018. Data were obtained from electronic medical records. The methodology of DRA identification was adapted from the OPERAM DRA adjudication guide.Results: Out of 1252 hospital admissions, 195 DRAs have been identified (145 related to treatment safety, 50 related to treatment effectiveness). The prevalence of DRAs was 15.6% (95% CI 13.6–17.6). The most common medication classes involved in DRAs related to treatment safety were Antithrombotic agents, Antineoplastic agents, Diuretics, Corticosteroids for systemic use, and Beta blocking agents. The most common medication classes involved in DRAs related to treatment effectiveness included Diuretics, Antithrombotic agents, Drugs used in diabetes, Agents acting on the renin-angiotensin system, and Lipid modifying agents. Gastrointestinal disorders were the leading causes of DRAs related to treatment safety, while Cardiac disorders were the leading causes of DRAs related to treatment effectiveness. The potential preventability of DRAs was 51%. The highest share of potential preventability in medication classes repeatedly involved in DRAs related to treatment safety was observed for Anti-inflammatory and antirheumatic products, Psycholeptics, and Drugs used in diabetes. Potentially preventable DRAs related to treatment safety were most commonly associated with inappropriate drug selection, inappropriate monitoring, inappropriate dose selection, and inappropriate lifestyle measures. On the contrary, DRAs related to treatment effectiveness were more commonly associated with medication nonadherence.Conclusion: It should be emphasized that in most DRAs, medications were only a contributory reason of hospital admissions and that benefits and risks have to be carefully balanced. It is highlighted by the finding that the same medication classes (Antithrombotic agents and Diuretics) were among the most common medication classes involved in DRAs related to treatment safety and simultaneously in DRAs related to treatment effectiveness. The study highlighted that apart from problems related to prescribing, problems related to monitoring and patient-related problems represent significant preventability aspects.

Abstract
The major challenges that delay the implementation of pharmacogenomics based clinical practice in the developing countries, primarily the low- and middle-income countries need to be recognized. This review was conducted to systematically review evidence of the cost-effectiveness for the conduct of pharmacogenomics testing in the developing countries. Studies that evaluated the cost-effectiveness of pharmacogenomics testing in the developing countries as defined by the United Nations were included in this study. Twenty-seven articles met the criteria. Pharmacogenomics effectiveness were evaluated for drugs used in the treatment of cancers, cardiovascular diseases and severe cutaneous adverse reactions in gout and epilepsy. Most studies had reported pharmacogenomics testing to be cost-effective (cancers, cardiovascular diseases, and tuberculosis) and economic models were evaluated from multiple perspectives, different cost categories and time horizons. Additionally, most studies used a single gene, rather than a gene panel for the pharmacogenomics testing. Genotyping cost and frequency of risk alleles in the populations influence the cost-effectiveness outcome. Further studies are warranted to examine the clinical and economic validity of pharmacogenomics testing in the developing countries.

Abstract
BACKGROUND Globally, it is estimated that the number of older adults will become 2 billion by 2050. The identification of the predictors of adverse drug reaction (ADR) in hospitalized older patients is crucial to the development of prediction tools and preventive strategies to mitigate the burden of ADRs. This study aimed to determine the predictors of hospital-acquired ADR occurrence among hospitalized older adults in a low-income country. METHODS We conducted a prospective cohort of older adults admitted to medical, oncology, and surgery wards at Mbarara Regional Referral Hospital (MRRH) for a consecutive 6 months where each patient was followed up daily from admission to discharge. We used Edwards and Aronson's definition of ADR and the Naranjo ADR Causality Scale. We employed Beer's criteria and Lexicomp to determine potentially inappropriate medications, and drug interactions, respectively. We conducted univariate and multivariable logistic regression using Statistical Package for the Social Science (SPSS) Version 23.0. RESULTS Out of 523 participants with median (Inter Quartile Range) age of 67 (62-76) years, 256 (48.9%) experienced at least one ADR. Independent predictors of occurrence of hospital acquired ADRs included age of 60-75 (Adjusted odds ratio (AOR) = 1.97, 95% C.I: 1.14-3.41; p value = 0.015) compared to > 75 years, previous ADR in 1 year (AOR = 2.43, 95% C.I: 1.42-4.17; p value = 0.001), potentially inappropriate medication (AOR = 4.56, 95% C.I: 2.70-7.70; p value< 0.001), polypharmacy (AOR = 3.29, 95% C.I: 1.98-5.46; p value< 0.001)), having a Charlison Comorbidity Index (CCI) ≥ 6 (AOR = 8.47, 95% C.I: 4.85-14.99; p value< 0.001), having heart failure (AOR = 2.83, 95% C.I: 1.34-6.02; p value = 0.007) or kidney disease (AOR = 1.95, 95% C.I: 1.05-3.61; p value = 0.034) and a hospital stay > 10 days (AOR = 3.53, 95% C.I: 1.89-6.61; p value< 0.001) compared to < 5 days. CONCLUSION The current prevalence of ADR is higher than previously reported in high-income countries. Disease-related factors followed by medication-related factors were shown to be the most important predictors of hospital-acquired ADRs. CCI and PIM showed the strongest association with ADR. The predictors of ADRs identified in our study were generally comparable with those reported by previous studies. PLAIN LANGUAGE TITLE Conditions that predispose older patients to experience harmful effects from their medications while in hospital. Identifying the conditions that predispose older adults to incur harmful effects of their medications helps to plan on how best to predict, take precautions and closely follow up on them and thus, to prevent these undesirable outcomes. This study aimed to identify these conditions which determine which older adults are higher risk to incur these harmful undesirable effects of medicines. Everydayduring their hospital stay, we closely followed older patients who were 60 years and above from their entry to the hospital wards until they left the hospital. We interviewed the participants, reviewed their medication files and we also examined them physically to identify any unwanted and harmful outcome from their current medications. Out of 523 participants, almost half of them experienced at least one harmful or undesired effect related to their medicine. Conditions which predisposed them to experience a harmful effect from their medicines included being in age bracket of 60-75 years, having a history of experiencing harmful outcomes from medicines in the previous 1 year, taking a medication which was listed as potentially inappropriate for older adults, taking 5 or more medications concurrently, having a lower 10 years survival chance, having heart or kidney disease and a hospital stay > 10 days.

Abstract
Background Few Saudi studies have examined adverse drug reactions (ADRs) in patients with rheumatoid arthritis (RA) receiving intravenous (IV) originator biologics. Therefore, this study aimed to evaluate the prevalence, types, and predictors of ADRs following long-term IV originator biologic use in patients with RA. Patients and methods This retrospective, single-center study included adult patients with RA who received IV originator biologics between 2015 and 2020. Medical records were reviewed and data regarding ADRs were collected and evaluated for causality using the Naranjo scale. Binary logistic regression analysis was performed to identify the odds for and factors associated with developing ADRs for each biologic. Results A total of 129 patients (87.6% women) with a mean (standard deviation) age of 54 (13) years were included in this study. A total of 1963 doses of tocilizumab (38.76%), rituximab (38.76%), abatacept (13.95%), and infliximab (8.53%), were administered during the study period. ADRs with a Naranjo score ≥ 1 were experienced by 103 (78%) patients, with an average of 2.2 events per patient. Infection (26.6%) and skin and mucous membrane disorders (14.18%) were the most commonly reported ADRs. Abatacept was associated with a significantly higher risk of multiple ADRs than the other biologics (adjusted odds ratio: 3.145, 95% confidence interval 1.004–9.854, p = 0.049). Conclusion There was a high prevalence of ADRs among patients with RA receiving biologics. Abatacept was associated with a greater risk of multiple ADRs than other biologics. Infection was the most common ADR. Future multicenter longitudinal studies are warranted.

Drug-Related Hospital Admissions and Associated Factors among Adults Admitted to Felege Hiwot Comprehensive and Specialized Hospital, North West Ethiopia. JOURNAL OF ENVIRONMENTAL AND PUBLIC HEALTH 2022; 2022:6767488. [PMID: 35391834 PMCID: PMC8983245 DOI: 10.1155/2022/6767488] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 10/09/2021] [Revised: 02/28/2022] [Accepted: 03/10/2022] [Indexed: 01/13/2023]
Abstract
Background A drug-related problem (DRP) is an event involving drug therapy that actually or potentially interferes with the desired therapeutic outcome. Drug-related hospital admission (DRHA) is hospitalization due to one or more DRPs. Objective This study was aimed at assessing the prevalence of DRHA and factors associated with it among adults admitted to the internal medicine wards of Felege Hiwot Comprehensive Specialized Hospital. Methods A prospective cross-sectional study was conducted using a previously validated tool, AT-HARM 10. Data were collected by two clinical pharmacists from July 1 to September 15, 2020. The data were entered into EpiData software (version 4.2.0.0) and then transported to Statistical Package for Social Sciences (SPSS®) software (version 24) (IBM Corporation) for analysis. Descriptive statistics were presented using frequency and proportion. Binary logistic regression was applied to identify factors associated with DRHAs with a 95% confidence level, and significance was declared at a p value <0.05. Results The prevalence of DRHAs was 31.9% (95% CI = 27.7%–36.4%). From this, noncompliance (37.8%) (95% CI = 29.6–45.9), untreated indication (31.9%) (95% CI = 23.7–40), and adverse drug reaction (15.6%) (95% CI = 9.6–21.5) cause the majority of DRHAs. More than a quarter (28.8%) of all admissions were preventable. Most DRHAs were moderate (76.3) and preventable (80.7%). Lower to medium Charlson comorbidity index scores, longer duration of therapy, and not having health insurance were significantly associated with DRHAs. Conclusion The prevalence of DRHAs was considerably high. Noncompliance, untreated indications, and adverse drug reactions were the commonest DRPs that caused DRHAs. Lower to medium Charlson comorbidity index scores, longer duration of therapy, and not having health insurance were significantly contributing factors of DRHAs. Therefore, all healthcare providers should prevent, identify, and resolve DRPs to decrease DRHAs in the hospital.

Ther Adv Drug Saf 2022; 13:20420986221080796. [PMID: 35295667 PMCID: PMC8918755 DOI: 10.1177/20420986221080796] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Accepted: 01/27/2022] [Indexed: 11/16/2022] Open
Abstract
Aim: Trends in the incidence of adverse drug reaction (ADR)–related hospitalizations have been studied in the general population, but not specifically in people with dementia. This study aimed to investigate trends in the incidence of ADR-related hospitalizations among people with dementia, and identify the most commonly implicated drugs and diagnoses in these admissions. Methods: This study utilized the administrative data of all adults admitted to the four major public hospitals of Tasmania, Australia, with a primary or secondary diagnosis of dementia from July 2010 to December 2019. ADR-related hospitalizations were identified by using diagnosis-based and external cause codes. The Cochran–Armitage test was used to examine trends in the incidence of ADR-related hospitalizations. Results: Of the 7552 people with dementia admitted to the hospital at least once within the study period, 1775 (23.5%) experienced at least one ADR-related hospitalization. The estimated annual incidence of ADR-related hospitalizations increased 18% (1484–1760 per 100,000 population with dementia, p for trend <0.05) from 2010 to 2019. For those ADR-related admissions with a drug code recorded, 19.3% were due to antithrombotics and 11.5% to antihypertensives. The most frequent ADR-related admission diagnoses were renal diseases (72.9%). Length of hospital stay and in-hospital mortality were both significantly greater for ADR-related, relative to non-ADR-related, admissions (median 7 versus 5 days and 11% versus 6.7%, respectively; p < 0.001). Conclusion: The annual incidence of ADR-related hospitalizations in people with dementia increased between 2010 and 2019. Antithrombotics were the most commonly implicated drug class. The ADR-related hospitalizations were associated with increased length of stay and greater mortality. Plain Language Summary Adverse drug reaction–related hospitalizations among people with dementia Introduction: This study aimed to investigate trends in hospitalizations associated with medication problems among people with dementia, and identify the most commonly implicated drugs and diagnoses in these admissions. Methods: This study utilized the administrative data of all adults admitted to the four major public hospitals of Tasmania, Australia, with dementia from July 2010 to December 2019. Results: The annual incidence of hospitalizations associated with medication problems among people with dementia increased nearly 20% over 10 years. The length of hospital stay and in-hospital mortality were significantly greater for hospitalizations related to medication problems. Conclusion: The incidence of hospitalizations associated with medication problems in people with dementia increased between 2010 and 2019.

Abstract
Objective To determine the harms of ezetimibe in people who need lipid-lowering treatment. Design Systematic review and meta-analysis. Data sources Randomised controlled trials and cohort studies. Eligibility criteria for selecting studies Studies comparing ezetimibe with placebo, standard care, or other lipid-lowering agents in people who need lipid-lowering treatment with a follow-up duration of at least six months (or 24 weeks). The relative effects for potential harms of ezetimibe were pooled by use of random effect pairwise meta-analyses for randomised controlled trials and the evidence from observational studies was narratively summarised. The certainty of evidence was assessed using the Grading of Recommendation Assessment, Development, and Evaluation. Results 48 randomised controlled trials with 28 444 participants (median follow-up 34 weeks, range 24-312 weeks) and four observational studies with 1667 participants (median follow-up 282 weeks, range 72-400 weeks) were included. The meta-analyses of randomised trials showed moderate to high certainty that ezetimibe was not associated with cancer (relative risk 1.01; 95% confidence interval 0.92 to 1.11), fractures (0.90; 0.74 to 1.10), discontinuation due to any adverse event (0.87; 0.74 to 1.03), gastrointestinal adverse events leading to discontinuation (1.34; 0.58 to 3.08), myalgia or muscular pain leading to discontinuation (0.82; 0.51 to 1.33), neurocognitive events (1.48; 0.58 to 3.81), or new-onset diabetes (0.88; 0.61 to 1.28). The narrative analysis of observational studies provided consistent findings. No credible subgroup effects were identified for the harm outcomes, including shorter versus longer follow-up duration of trials. Conclusions Ezetimibe results in little to no difference in adverse events or other undesirable effects compared with placebo, usual care or other lipid-lowering agents. Review registration PROSPERO CRD42020187437.

Abstract
Drug safety in paediatric patients is a serious public health concern around the world. The paediatric patients are more prone to adverse drug reactions (ADRs) than adults. Moreover, there is a scarcity of information about ADRs in paediatric patients. This study was conducted to determine the frequency, causality, severity, preventability of paediatric patients’ ADRs reported in a tertiary care hospital in Adana, Turkey. A retrospective study was conducted on all spontaneously reported ADRs between January 01, 2020, to July 30, 2021, in paediatric patients. The ADRs reports were evaluated in terms of gender, age, ADR characteristics, suspected drugs and reporting source. All included ADRs reports were characterized according to the Naranjo Algorithm/World Health Organization (WHO) causality scales, Hartwig/Siegel and Common Terminology Criteria for Adverse Events (CTCAE) severity scales, the modified Schoumock and Thornton preventability scale and hospital pharmacovigilance center criteria for seriousness. Therapeutic groups were also coded using the WHO-Anatomical Therapeutic and Chemical (ATC) classification. During the study period, 8,912 paediatric patients who were admitted had 16 ADRs with 1.7 ADRs/1,000 admissions. The majority of ADRs were found in infants (31.2%) and children (56.2%) as compared to adolescents (12.5%). ADRs were observed more in females (81.2%) than males. Skin (62.5%) was the most affected organ due to the ADRs, and maculopapular rash and erythema multiforme were the most commonly reported symptoms. Most ADRs were probable/likely (93.7%), severe (50%), preventable or probably preventable (43.7%) and serious (37.5%). Antibiotics (93.7%) were found to be the most common cause of ADRs in paediatric patients. The majority of ADRs were associated with vancomycin (68.7%). Most of the ADRs were reported by a medical doctor in this study. This small sample size study highlights significant problems of ADRs in paediatric patients, mainly caused by antibiotics and with a majority of ADRs manifest as skin reactions. Furthermore, a high proportion of the identified ADRs were found to be preventable. More focused efforts are needed at the national level to avoid preventable ADRs in hospitals. Monitoring and management of ADRs and future studies would be beneficial for better patient care and safety.

Abstract
We aimed to summarize and describe the burden of serious adverse drug reactions (ADRs) in sub-Saharan Africa (SSA) in the era of antiretroviral therapy. We searched Medline, CINAHL, Africa-Wide Information, Scopus, and Web of Science, without language restriction up to March 2021. We hand-searched reference lists, conference abstracts, and dissertation databases. We included studies reporting proportions of admissions attributed to ADRs, admissions prolonged by ADRs, or in-hospital deaths attributed to ADRs. Two reviewers independently screened the studies, reviewed the study quality using a previously published tool, and extracted the data. We tested for heterogeneity using I2 -statistics and summarized the study results using medians and interquartile ranges. Subgroup analyses summarized the results by study quality, setting, methodology, and population. From 1005 unique references identified, we included 15 studies. Median study quality was 7/10; heterogeneity was very high. Median [IQR] proportion of admissions attributed to ADRs was 4.8% [1.5% to 7.0%] (14 studies) and 6.4% [4.0% to 8.4%] in nine active surveillance studies in adults. Two pediatric studies reported the proportion of admissions prolonged by ADRs (0.29% and 0.99%). Three studies reported the proportion of in-hospital deaths attributed to ADRs (2.5%, 13%, and 16%). Antiretroviral and antituberculosis drugs were often implicated in serious ADRs. Evidence of the burden of serious ADRs in SSA is patchy and heterogeneous. A few high-quality studies suggest that the burden is considerable, and that it reflects the regional impact of the HIV pandemic. Further characterization of this burden is required, ideally in studies of standardized methodology.

Abstract
Background Adverse drug reactions (ADRs) constitute a significant global healthcare challenge associated with increased morbidity, mortality and healthcare costs; however, there are concerns that ADRs are grossly under-reported by different categories of healthcare professionals (HCPs) in many countries. The main objective of this study was to assess the knowledge, attitude and practice of ADR reporting of HCPs working at the primary, secondary and tertiary levels of care in Ekiti State, Nigeria. Methodology This was a self-administered questionnaire-based study conducted among HCPs working in Ekiti State, South-west Nigeria. The questionnaire which was adapted from ones used in similar studies was reviewed for content validity by experts in the field. Healthcare professionals (medical doctors, pharmacists, nurses, community health extension workers, and other allied HCPs) working in the 3 tiers of healthcare participated in the study. The questionnaire consisted of sections on the demographics of respondents, their knowledge, attitude and practice of ADR reporting. Data analysis was done using SPSS (version 25) employing t test, ANOVA and chi-square as appropriate with P-value < .05 accepted as being statistically significant. Results Three hundred HCPs comprising of nurses (112; 37.3%), physicians (75; 25.0%), pharmacists (53; 17.7%), community health extension workers (40; 13.3%) and others (20; 6.7%) completed the questionnaire with 166 (55.3%) of them working in tertiary healthcare facilities. Male respondents (6.3 ± 1.7; P = .003), pharmacists (7.0 ± 1.6; P < .0001), HCPs and those from tertiary centers (6.2 ± 1.7; P = .028) had higher knowledge scores. While 228 (76%) respondents had observed incidents of ADR during their professional practice, only 75 (25%) have ever reported it. Only 113 (37.7%) of respondents had seen the adverse drug reaction reporting form with only 53 (17.7%) ever using it. The reporting methods preferred by respondents were through email/internet (102; 34.0%), phone/SMS (78; 26.0%) and using the hard copy of the forms (95; 31.7%). The attitude of respondents towards ADR reporting was mainly positive. Conclusion There was significant variation in the knowledge of different categories of HCPs and facility levels about ADR reporting. Encouragingly, the overall attitude of respondents towards ADR reporting was positive. Based on the above, strategies are needed to build capacity of HCPs in the area of on adverse drug reaction and its' reporting.

Abstract
PURPOSE Adverse drug events are related to negative outcomes in healthcare, including hospitalization, increased duration of hospital stay and death. The aim of this study was to conduct a systematic review to evaluate hospitalizations and deaths related to adverse drug events worldwide, reported in studies with national coverage. METHODS The protocol was registered in PROSPERO (CRD42020157008). We performed a systematic search on Medline, Embase, CINAHL, LILACS, and the Cochrane Library (until March 2020) using pre-specified terms. We included published studies that reported data on hospitalizations and/or deaths related to adverse drug events from a national perspective and the use of secondary data as a source of information. Two reviewers independently extracted and synthesized data. The quality of the studies was assessed using an adapted version of the Joanna Briggs Institute critical appraisal checklist for prevalence studies. Narrative summaries of findings were undertaken. RESULTS Among 59,336 citations, 62 studies were included for data extraction and synthesis. Among these studies, 41 studies included the outcome of hospitalization, 16 included the death outcome, and five included both outcomes. Administrative databases regarding discharges and registries of vital statistics were the most common sources of information. The relative frequency of hospitalizations ranged from 0.03% to 7.3%, and from 9.7 to 383.0/100,000 population, whereas mortality rate ranged from 0.1 to 7.88/100,000 population. CONCLUSION Our study highlights information about adverse drug events using large administrative databases in a national scenario and provides an overview of databases and methods implemented to detect adverse drug events.

Abstract
PURPOSE To estimate the prevalence of drug-related deaths with regard to total hospital mortality and to explore the heterogeneity in its estimation through subgroup analysis, univariate and multivariate analysis. METHODS Two investigators independently searched the PubMed and Google Scholar databases with appropriate key terms to identify observational and randomised studies assessing drug-related problems. The prevalence of drug-related deaths was estimated using a double arcsine method. The heterogeneity was explored through subgroup and univariate analysis for the following study characteristics: study design, age group, study ward, study region, types of drug-related problems, study duration, sample size and study period. The study variables showing significant effects were further explored through a multivariable regression model. The percentage of preventable drug-related deaths was explored as a secondary objective. RESULTS Of the 480 full-text articles assessed, 23 studies satisfying the selection criteria were included. The mean percentage of drug-related deaths was 5.6% (95% CI: 3.8-7.6%; I2 = 96%). The univariable analysis showed study design (regression coefficient: 4.31) and study wards (regression coefficient: - 6.37) as heterogeneity modifiers. In the multivariable model, only the study ward was considered a significant predictor of drug-related deaths (regression coefficient: - 5.78; p = 0.04). The mean percentage of preventable drug-related deaths was 45.2% (95% CI: 33.6-57.0%; I2 = 60%). CONCLUSION Drug-related problems are an important cause of mortality. The variability in its estimation could be explained by admission wards.

Abstract
Background Adverse drug reactions (ADRs) are associated with significant clinical and economic effects. Among the elderly population, the risk for ADRs is even higher. Data of ADR prevalence and incidence among the elderly population in Uganda and many low- and middle-income countries are lacking. Objective This study determined the prevalence, incidence, and characteristics of ADRs among hospitalized elderly patients at Mbarara Regional Referral Hospital (MRRH), Uganda. Methods and Materials We conducted a prospective cohort of older adults admitted to medical, oncology, and surgery wards at MRRH for consecutive 6 months. The primary data were obtained by interviewing patients and caregivers and reviewing patient medication charts, taking vital signs, and physical examinations. We used Edwards and Aronson’s definition of ADR and the Naranjo ADR Causality Scale. We conducted descriptive statistics and the Kolmogorov–Smirnov test using SPSS Version 23.0. Results We studied a total of 523 older adults 60 to 103 years of age. During their hospital stay, 256 (48.9%) of the patients experienced at least one ADR. A total of 365 ADRs were identified during 4702 person-days of follow-up. The incidence of ADRs was 78 ADRs/1000 person-days. ADRs affecting the gastrointestinal tract were the most frequently (40.6%) identified categories. Probable and type A ADRs accounted for 260 (71.2%) and 305 (83.6%) of the total incidents, respectively. Overall, 237 (64.9%) of the ADRs were rated as mild, whereas 10 (2.8%) of them as severe. Lastly, 165 (45.2%) of the ADRs were categorized as preventable. Conclusion Almost half of the hospitalized patients aged 60 to 103 years experienced at least one ADR during their hospital stay, which is higher than has been previously documented. Almost three-thirds of the ADRs were probable, about 4 out of 5 were type A and almost two-thirds were mild. Nearly half of the ADRs were preventable.

Abstract
INTRODUCTION Adverse drug reactions are an important public health concern that affects doctor and dentist prescriptions and healthcare workers' practice. We planned to evaluate the knowledge, attitudes and practices of healthcare workers in our country about drug hypersensitivity reactions in paediatric patients and to determine the risk factors that may affect them. METHOD This study was carried out in a capital-located university hospital. Healthcare workers authorized to intervene in children (0-18 age group), including medical doctors, nurses, and dentists, were enrolled in the study. The study questionnaire was developed by paediatric allergy and immunology specialists and paediatric nurses by considering the other studies on the same subject. RESULTS Three hundred fifty-four (88.5%) out of 400 healthcare workers, whose study survey was distributed, returned to us by filling the questionnaire. According to the groups of the profession, there was a statistically significant difference between the average of correct answers given to the questions evaluating knowledge levels (P < .001). The doctors' knowledge score (M ± SD 18.6 ± 2.1) was the highest. The general attitudes of healthcare workers towards drug hypersensitivity reactions in children were similar and were positive (P < .053). However, general practice patterns were significantly different (P < .001). Nurses were observed to practice more positively than doctors and dentists. As the healthcare worker gets older, his practice score increased by 0.546; on the other hand, being a resident reduced the score from the practice score by 3.770. CONCLUSION Our results suggest that advanced training programmes must be provided for healthcare workers in learning drug hypersensitivity reactions, particularly in paediatric patients.

Abstract
BACKGROUND Occurrence of adverse drug reactions is a major global health problem mostly affecting older adults. Identifying the magnitude and predictors of adverse drug reactions is crucial to developing strategies to mitigate the burden of adverse drug reactions. This study's objectives were to estimate and compare the prevalences of adverse drug reactions, to characterize them and to identify the predictors among hospitalized older adults. METHODS A comprehensive systematic literature search including both prevalence and risk factors of adverse drug reactions in hospitalized older adults was conducted using PubMed, Scopus and Google Scholar, involving all articles published in English. Descriptive statistics and comparison of means was performed using SPSS version 20.0 and metaprop command was performed in STATA version 13.0. Heterogeneity was assessed using I 2 statistic. RESULTS A total of 18 studies, involving 80,695 participants with a median age of 77 years, were included in this study. The pooled prevalence of adverse drug reaction was 22% (95% confidence interval: 17%, 28%; I 2 = 99.23%). Among high-income countries, the prevalence of adverse drug reactions was 29% (95% confidence interval: 16%, 42%) as compared to 19% (95% confidence interval: 14%-25%) in low and middle-income countries (p value = 0.176). Of the 620 adverse drug reactions categorized, most were type A (89%), which are generally predictable and preventable. Two-thirds (795, 67%) of the adverse drug reactions were probable and most (1194, 69%) were mild or moderate. The majority (60%) of the categorized adverse drug reactions were preventable and less than one-third (31%) were severe. The most consistently reported predictors of adverse drug reactions in hospitalized older patients were medication-related factors, including polypharmacy and potentially inappropriate medications followed by disease-related factors-renal failure, complex comorbidity, heart failure and liver failure. CONCLUSION Almost one-quarter of all hospitalized older adults experienced at least one adverse drug reaction during their hospital stay. The majority of the adverse drug reactions were preventable. Medication-related factors were the most consistently reported predictors of adverse drug reactions followed by disease-related factors.

Abstract
Background Medication harm can lead to hospital admission, prolonged hospital stay and poor patient outcomes. Reducing medication harm is a priority for healthcare organisations worldwide. Recent Australian studies demonstrate cardiovascular (CV) medications are a leading cause of harm. However, they appear to receive less recognition as ‘high risk’ medications compared with those classified by the medication safety acronym, ‘APINCH’ (antimicrobials, potassium, insulin, narcotics, chemotherapeutics, heparin). Our aim was to determine the scale and type of medication harm caused by CV medications in healthcare. Methods A narrative review of adult (>16 years) medication harm literature identified from PubMed and CINAHL databases was undertaken. Studies with the primary outcome of measuring the incidence of medication harm were included. Harm caused by CV medications was described and ranked against other medication classes at four key stages of a patient’s healthcare journey. Where specified, the implicated medications and type of harm were investigated. Results A total of 75 studies were identified, including seven systematic reviews and three meta-analyses, with most focussing on harm causing hospital admission. CV medications were responsible for approximately 20% of medication harm; however, this proportion increased to 50% in older populations. CV medications were consistently ranked in the top five medication categories causing harm and were often listed as the leading cause. Conclusion CV medications are a leading cause of medication harm, particularly in older adults, and should be the focus of harm mitigation strategies. A practical approach to generate awareness among health professionals is to incorporate ‘C’ (for CV medications) into the ‘APINCH’ acronym. Plain language summary

Abstract
BACKGROUND Pharmacovigilance (PV) demarcates all actions involving the detection and prevention of adverse drug reactions (ADR) for marketed drugs. However, ADRs are considerably underreported worldwide and continue to be a major concern to health care systems. This study aims to assess the knowledge, attitude, and perception of hospital pharmacists regarding medication safety concerning PV and ADRs across multiple tertiary care centers around Saudi Arabia. METHODS This cross-sectional study was conducted between July 2019 and January 2020. Pharmacists working in the tertiary care centers of Riyadh City, Saudi Arabia were asked to participate in the study. A self-administered questionnaire was used to conduct this study, it consisted of: 63 questions out of which 19 questions were knowledge-based, 15 were attitude-based, and 29 were practice-based questions. RESULTS A total of 350 pharmacists were distributed and 289 agreed to participate, giving a response rate of 82.6%. Most pharmacists were aware of the concept of VP and its functions (96.5%) and (87.2%), respectively. Moreover, 90% said that ADR can be preventable and non-preventable. However, the findings revealed inadequate knowledge about the overall PV field, where the majority of the pharmacists failed to correctly answer questions related to independent ADRs treatment, Augmented drug reaction, the international location of ADR, and the World Health Organization "online database" for reporting ADRs. Moreover, incomplete and/or wrong answers were recorded for questions that included single or multiple correct answers. Regarding the participants" attitude, 96.9% were interested in ADR reporting, agreeing that ADR is important to enable safe drug usage. Although a general positive attitude was recorded, pharmacists have stated that the three main barriers that hinder reporting ADRs are: unavailability of information about ADRs, lack of awareness about the need to report ADRs, and lack of time. Concerning practice, 69.2% said they received training in ADRs reporting, and 70% have reported ADRs more than once a week. CONCLUSION Surveyed pharmacists from Riyadh hospitals showed narrow knowledge of the PV field. However, a positive attitude and satisfactory practice was observed among pharmacists. These findings warrant the need for educational programs and an encouraging environment for ADR reporting to increase ADR reporting rates and support PV activities in Saudi Arabia.

Abstract
BACKGROUND Around 2 billion people globally were affected by natural disasters between 2008-2018. The World Health Organization requires countries and governments to have disaster plans and emergency health workers ready and prepared at all times. OBJECTIVES To conduct an integrative review of literature of emergency healthcare workers' perceived preparedness for disaster management. METHODOLOGY An integrative literature review using the PRISMA checklist guidelines was conducted to explore physicians, nurses, emergency medical services and allied medical professionals' preparedness for disasters. Literature was searched from 2005, published in the English language and from MEDLINE (PubMed), Google Scholar, EMBASE, PsycINFO, SCOPUS, ProQuest and CINAHL databases. Reviews, case reports, clinical audits, editorials and short communications were excluded. Studies were critically appraised using the Mixed Methods Appraisal Tool. RESULTS The initial search yielded 9589 articles. Twenty-seven articles were included following application of the eligibility criteria. Included studies were geographically diverse including North America, the Middle East and the Asia Pacific. Most studies (n = 24) assessed the knowledge of healthcare workers in general disasters. Studies using the Disaster Preparedness Evaluation Tool reported moderate disaster preparedness and knowledge, while studies using other instruments largely reported inadequate disaster preparedness and knowledge. Regional variations were recorded, with high-income countries' reporting a higher perceived preparedness for disasters than low-income countries. CONCLUSION The majority of the emergency healthcare workers appear to have inadequate disaster preparedness. Previous disaster experience and training improved disaster preparedness. Future research should focus on interventions to improve emergency healthcare workers preparedness for disasters.

Abstract
BACKGROUND Adverse drug reactions (ADRs) represent a major cause of iatrogenic morbidity and mortality in patient care. While a substantial body of work has been undertaken to characterise ADRs in the hospital setting, the overall burden of ADRs in the primary care remains unclear. OBJECTIVES To investigate the prevalence of ADRs in the primary care setting and factors affecting the heterogeneity of the estimates. METHODS Studies were identified through searching of Medline, Embase, CINAHL and IPA databases. We included observational studies that reported information on the prevalence of ADRs in patients receiving primary care. Disease and treatment specific studies were excluded. Quality of the included studies were assessed using Smyth ADRs adapted scale. A random-effects model was used to calculate the pooled estimate. Potential source of heterogeneity, including age groups, ADRs definitions, ADRs detection methods, study setting, quality of the studies, and sample size, were investigated using sub-group analysis and meta-regression. RESULTS Thirty-three studies with a total study population of 1,568,164 individuals were included. The pooled prevalence of ADRs in the primary care setting was 8.32% (95% CI, 7.82, 8.83). The percentage of preventable ADRs ranged from 12.35-37.96%, with the pooled estimate of 22.96% (95% CI, 7.82, 38.09). Cardiovascular system drugs were the most commonly implicated medication class. Methods of ADRs detection, age group, setting, and sample size contributed significantly to the heterogeneity of the estimates. CONCLUSION ADRs constitute a significant health problem in the primary care setting. Further research should focus on examining whether ADRs affect subsequent clinical outcomes, particularly in high-risk therapeutic areas. This information may better inform strategies to reduce the burden of ADRs in the primary care setting.

Abstract
OBJECTIVE Transitional care is important to successful hospital discharge. Providing patients with a clear and concise summary of medication-related information can help improve outcomes, in particular, among older adults. The present study aimed to propose a framework for the development of salient medication reminders (SMR), which include drug-related risks and precautions, using the Delphi process. DESIGN Identification of potential SMR statements for 80% of medication types used by older adult patients discharged from geriatric medicine departments, followed by a Delphi survey and expert panel discussion. SETTINGS Medical and geriatric departments of public hospitals in Hong Kong. PARTICIPANTS A panel of 13 geriatric medical experts. OUTCOME MEASURE A Likert scale ranging from 1 (strongly disagree) to 5 (strongly agree) points, scoring item relevance, importance and clarity. The minimum of 70% consensus was required for each statement to be included. RESULTS The expert panel achieved consensus through the Delphi process on 80 statements for 44 medication entities. Subsequently, the SMR steering group endorsed the inclusion of these statements in the SMR to be disseminated among older adults at the time of discharge from geriatric medicine departments. CONCLUSIONS The Delphi process contributed to the development of SMR for older adult patients discharged from public hospitals in Hong Kong. Patient experience with and staff response to the SMR were assessed at four hospitals before implementation at all public hospitals.

Abstract
PROPOSE Underreporting of Adverse Drug Reactions (ADRs) reduces the sensitivity of pharmacovigilance systems. We described ADR reporting and its trend from 1999 to 2017 and estimated the ADR underreporting in the Iranian Pharmacovigilance Center. METHODS We expressed the number of ADR reporting per inhabitants and admissions and their possible trends. Finally, ADR underreporting percentages were estimated by three approaches: prospective studies, literature review, stratification of the country; and the trend of the proportion of ADR per inhabitants was corrected. RESULTS The proportion of ADR reporting was 15.3 per 100 000 inhabitants (95% CI: 15.2, 15.8) and 10.0 per 100 000 admissions (95% CI: 9.8, 10.2) in 2017, and its trend was increasing with 16.3% average change per annum during 19 years. The median of estimated percentages of underreporting was 76.0% (IQR: 64.32-81.35). After the correction, the mean proportion of ADR reporting for 19 years reached from 5.87 to 10.33 per 100 000 inhabitants. CONCLUSIONS The trend of ADRs reporting has been increasing over the 19 years but is still low. This study showed a considerable underreporting of ADR, and about one of four detected ADRs were reported to the pharmacovigilance center from 1999 to 2017.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18052674. [PMID: 33799926 PMCID: PMC7967518 DOI: 10.3390/ijerph18052674] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/31/2021] [Revised: 02/27/2021] [Accepted: 03/02/2021] [Indexed: 01/15/2023]
Abstract
There is a consensus that elderly individuals are quite vulnerable to adverse drug reactions (ADRs), and headaches are one of the most frequent clinical presentations of central nervous system problems in the general population, which can be an ADR. The purpose of our work was to analyze reports of "headache" associated ADRs in the elderly sent to the Portuguese Pharmacovigilance System (PPS), and also which drugs were more frequently associated with this adverse reaction. A retrospective analysis of suspected ADR reports involving patients aged 65 years or older received by the PPS in the last 10 years was conducted. A search of all the terms associated with the High Level Term "headache" was performed. All duplicate reports were excluded from the analysis. A total of 155 ADRs reports were included, in which 15 reported isolated "headache" as suspected ADR, while the remaining 140 ADRs reports reported "headache" together with several other adverse reactions. Most reports of "headache" ADR occurred in women (74.8%; n = 116). About half (46.5%; n = 72) of the ADR reports were considered serious. Anti-viral medication, anti-depressants, anti-dyslipidemic agents and central nervous system-acting analgesics were the most frequent drugs associated with "headache" ADR reports in this population. In elderly patients, most ADR reports involving headaches occurred in women and a high percentage (46.5%) were considered serious. Thus, it is important that healthcare professionals pay more attention to headaches reported as ADRs in the elderly and drugs suspected to cause them, in order to increase knowledge about this type of reaction and contribute towards safely using drugs in this age group.
