Background: Retrospective analyses of large databases of treated patients can provide useful links to the presence of drug misuse or rare and infrequent adverse effects, such as agranulocytosis, diabetic ketoacidosis or neuroleptic malignant syndrome. The aim of this study is to describe the adverse effects to antipsychotics reported in the Australian Database of Adverse Event Notifications (DAEN). Methods: Data were collected from the DAEN – a spontaneous reporting database. The database, which covered the period from January 2004 to December 2017, was obtained from the Therapeutic Goods Administration (TGA) website ( www.TGA.gov ). The drugs selected for this investigation are the following: aripiprazole, clozapine, olanzapine, paliperidone, risperidone, ziprasidone, quetiapine, haloperidol and pimozide. All data were analysed descriptively. Comparison of reporting and management of adverse events between adults (older than 20 years) and children (5–19 years) was undertaken using chi squared test, where p < 0.05 is significant. Results: A total of 7122 adverse events associated with the antipsychotics aripiprazole, clozapine, haloperidol, olanzapine, paliperidone, pimozide, quetiapine and risperidone were reported to the TGA between January 2004 and December 2017. On average, there were 2.6 adverse events reported for each case. The most common adverse event reported for antipsychotics was neuroleptic malignant syndrome. There were no significant differences in the number of co-medications, formulations, indications, therapeutic dose, hospital admission and overdose among the antipsychotics between paediatric and adult populations. However, there were significant differences between causality, death and the management of adverse events between adult and paediatric populations (5–19 years) ( p < 0.05, chi squared test). Conclusion: The antipsychotic drug associated with the highest adverse events in adults was clozapine, followed by olanzapine. The most common adverse event in adults, and reported with a number of antipsychotic drugs, was neuroleptic malignant syndrome. In children, the highest numbers of adverse events reported in the database were associated with risperidone, clozapine and olanzapine. Plain language summary Adverse events reported of antipsychotics Background: Retrospective analyses of large databases of treated patients can provide useful clues to the presence of drug misuse or rare and infrequent adverse effects associated with antipsychotics. The drugs selected for this investigation are the following: aripiprazole, clozapine, olanzapine, paliperidone, risperidone, ziprasidone, quetiapine, haloperidol and pimozide. Methods: All data were analysed descriptively and investigated for any associations between the variables collected. Comparison of reporting and management of adverse events between adults (older than 20 years) and children (5–19 years) was undertaken using chi squared test, where p < 0.05 is significant. Results: The antipsychotic drug associated with the highest adverse events was clozapine, followed by olanzapine. In children, the highest numbers of adverse events reported in the database were associated with risperidone, clozapine and olanzapine. The most common adverse event in adults, and reported with a number of antipsychotic drugs, was neuroleptic malignant syndrome. Conclusion: There were significant differences between causality, death and the management of adverse events between adult and paediatric populations (5–19 years).Keywords: Antipsychotics, adverse effects, adverse events, safety

Abstract Background Clinical practice guidelines (CPGs) recommend the monitoring of somatic parameters in patients treated with antipsychotic drugs in order to detect adverse effects. The objective of this study was to assess, in adult and (frail) elderly populations, the consistency and applicability of the somatic monitoring instructions recommended by established CPGs prior to and during antipsychotic drug use. Methods A search for national and international CPGs was performed by querying the electronic database PubMed and Google. Somatic monitoring instructions were assessed for adult and (frail) elderly populations separately. The applicability of somatic monitoring instructions was assessed using the Systematic Information for Monitoring (SIM) score. Somatic monitoring instructions were considered applicable when a minimum SIM score of 3 was reached. Results In total, 16 CPGs were included, with a total of 231 somatic monitoring instructions (mean: 14; range: 0–47). Of the somatic monitoring instructions, 87% were considered applicable, although critical values and how to respond to aberrant values were only present in 28 and 52% of the available instructions respectively. Only 1 CPG presented an instruction specifically for (frail) elderly populations. Conclusions We emphasize the need for a guideline with somatic monitoring instructions based on the SIM definition for both adult and (frail) elderly populations using antipsychotic drugs. In addition, CPGs should state that clear agreements should be made regarding who is responsible for interventions and somatic monitoring prior to and during antipsychotic drug use.

Background: Patient demographics and operative techniques may contribute to adverse events after surgeries. Objective: To identify differences in adverse event rates between different dermatologic surgery centers and potential contributing features affecting these rates. Methods: Data regarding demographics, procedure type, and adverse events were collected at two dermatologic surgery centers. Results: The most common adverse event at both sites was infection: 2.1% at site 1 versus 0.5% at site 2 ( p < .001). Using multivariate logistic regression, procedure type (Mohs surgery), geographic location (being at site 1), older age, and anatomic location of surgery were associated with a higher risk of infection. Conclusion: Adverse event rate appears to correlate with patient demographics, procedure type, and setting of surgery more than use of prophylactic antibiotics. Identification of differences in adverse event rates and potential contributing variables at different practices may allow for identification of opportunities to prevent adverse events.

Hyperbaric oxygen therapy (HBOT) is commonly utilized for various human conditions with a low incidence of major adverse effects (0.002–0.035%). Despite growing use in veterinary patients, there remains a paucity of literature describing its use and associated complications. The purpose of this study was to report clinical use of HBOT in small animals and identify the rate of major adverse events at a university teaching hospital. Electronic medical records were searched for small animals receiving HBOT between November 2012 and February 2020. Data extracted from the medical records included signalment, treatment indication, and adverse events. Treatment sessions totaled 2,792 in 542 dogs, 24 cats, and 10 pocket pets and exotics. Common indications included neurologic injuries (50.4%), tissue healing (31.4%), control of oomycete infection (5.5%), neoplasia or post-radiation injury (5.4%), and various miscellaneous conditions (7.4%). Observed minor adverse events included agitation in two dogs and vomiting in three dogs. The most common major adverse event was central nervous system (CNS) oxygen toxicity in 19 dogs. Central nervous system oxygen toxicity, manifesting as focal or generalized seizures, occurred in 0.7% of treatment sessions, with increasing age (p = 0.01) and female sex (p = 0.01) identified as risk factors. One dog developed pulmonary edema following HBOT which is a reported adverse event in humans or may have been a manifestation of progression of the dog's underlying disease. No adverse events were noted in cats or other species. In conclusion, HBOT appeared safe across various indications, although oxygen toxicity affecting the CNS was higher than reports in humans. Future prospective, randomized, controlled trials should evaluate specific clinical indications and outcomes.

Background: Clients who seek veterinary care for pets with cancer are often concerned about the potential negative impact of chemotherapeutic treatments on their animals’ quality of life. A consensus currently exists in veterinary oncology regarding the quantification and rating of adverse treatment effects in dogs and cats in response to chemotherapy agents. This grading system is referred to as Veterinary Cooperative Oncology Group - Common Terminology Criteria for Adverse Events. The purpose of this retrospective case series was to investigate the delayed acute effects of chemotherapy drugs in cats receiving cancer treatment.Materials, Methods & Results: Medical records were reviewed to determine the chemotherapy agent used and delayed adverse effects. Side effects were classified according to Veterinary Co-operative Oncology Group grading. All cats were evaluated after the first chemotherapy administration, after a single dose. The reported effects included hematologic effects (e.g., neutropenia, thrombocytopenia, increases in liver enzymes, and azotemia), gastrointestinal effects (e.g., vomiting, diarrhea, and inappetence), and sepsis. All of the cats in this study received ondansetron and omeprazol  in the first five days following chemotherapy administration. If vomiting occurred with oral medication, maropitant was administered subcutaneously for three consecutive days. If diarrhea (> grade II) occurred, probiotics were administered for seven days. Hematologic examination was performed 3-14 days after chemotherapy. If neutropenia (> grade III) occurred, Human granulocyte colony stimulating factor was administered subcutaneously for three consecutive days together with prophylactic antibiotics. Lomustine, carboplatin, vincristine, doxorubicin, cyclophosphamide, mitoxantrone, and vinblastine were administered in 33%, 19%, 16%, 5%, 16%, 10% and 2% of the cases examined, respectively. The most common adverse events were vomiting, inappetence, neutropenia, and thrombocytopenia. Vomiting occurred in 6% cases, most of them associated with cyclophosphamide. Inappetence/anorexia affected 12% of the cases, mostly those involving cyclophosphamide or doxorubicin. Neutropenia was observed in 22% of the cases, with cyclophosphamide, followed by carboplatin and lomustine. According to the current grading system of adverse effects induced by chemotherapy, grade I toxicity was observed in 83% of the cases, whiles grade II-IV were observed in 7%, 8%, and 2% of the cases examined, respectively.Discussion: In general, the chemotherapy regimens in the cases examined were well tolerated. The toxicity experienced was infrequent and mostly mild, thereby resulting in satisfactory tolerability of the chemotherapy regimens. According to the current grading system for the adverse effects of chemotherapy, 83% of the cases examined included grade I, indicating that most of the cats experienced asymptomatic, or mild symptoms, and medical intervention was not needed. In previous studies of dogs and cats, a severe adverse event following chemotherapy was reported for fewer than 1 in 4 animals, and approximately 3-5% experienced a serious adverse event that led to hospitalization. In the present study, 2% of the cats experienced serious or life threatening adverse events. The only chemotherapeutic agent that was associated with inappetence, vomiting, and neutropenia was cyclophosphamide. Based on the data examined, we would recommend that cyclophosphamide should be used with caution for the treatment of cancer in cats, with adequate antiemetic and nutritional support available if needed. In addition, febrile neutropenia/sepsis may be avoided by using a fractionated schedule.

Background. Obstetrician-gynecologists are increasingly called upon to be vaccinators as an essential part of a woman’s primary and preventive health care. Despite the established safety of vaccines, vaccine adverse events may occur. A national Vaccine Adverse Event Reporting System (VAERS) is a well-established mechanism to track adverse events. However, we hypothesized that many obstetrician-gynecologists are naive to the role and use of VAERS.Methods. We devised a ten-question survey to a sample of ACOG fellows to assess their knowledge and understanding of VAERS. We performed descriptive and frequency analysis for each of the questions and used one-way analysis of variance for continuous and chi-squared for categorical variables.Results. Of the 1000 fellows who received the survey, 377 responded. Only one respondent answered all nine knowledge questions correctly, and 9.2% of physicians had used VAERS. Older physicians were less familiar with VAERS in general and with the specific objectives of VAERS in particular (χ2=10.7,P=.005).Conclusions. Obstetrician-gynecologist familiarity with VAERS is lacking. Only when the obstetrician-gynecologist is completely knowledgeable regarding standard vaccine practices, including the availability and use of programs such as VAERS, will providers be functioning as competent and complete vaccinators.

Grubbs Test

We systematically compared the adverse effects of cancer drugs to detect event outliers across different clinical trials using a data-driven approach. Because many cancer drugs are toxic to patients, better understanding of adverse events of cancer drugs is critical for developing therapies that could minimize the toxic effects. However, due to the large variabilities of adverse events across different cancer drugs, methods to efficiently compare adverse effects across different cancer drugs are lacking. To address this challenge, we present an exploration study that integrates multiple adverse event reports from clinical trials in order to systematically compare adverse events across different cancer drugs. To demonstrate our methods, we first collected data on 186,339 clinical trials from ClinicalTrials.gov and selected 30 common cancer drugs. We identified 1602 cancer trials that studied the selected cancer drugs. Our methods effectively extracted 12,922 distinct adverse events from the clinical trial reports. Using the extracted data, we ranked all 12,922 adverse events based on their prevalence in the clinical trials, such as nausea 82%, fatigue 77%, and vomiting 75.97%. To detect the significant drug outliers that could have a statistically high possibility of causing an event, we used the boxplot method to visualize adverse event outliers across different drugs and applied Grubbs’ test to evaluate the significance. Analyses showed that by systematically integrating cross-trial data from multiple clinical trial reports, adverse event outliers associated with cancer drugs can be detected. The method was demonstrated by detecting the following four statistically significant adverse event cases: the association of the drug axitinib with hypertension (Grubbs’ test, P < 0.001), the association of the drug imatinib with muscle spasm ( P < 0.001), the association of the drug vorinostat with deep vein thrombosis ( P < 0.001), and the association of the drug afatinib with paronychia ( P < 0.01).

Introduction: Sugammadex is used for the reversal of neuromuscular blockade caused by rocuronium bromide and vecuronium bromide. As part of the post licensing phase of drug development, adverse events related to the use of sugammadex are still being uncovered and being reported. The potential association between sugammadex and adverse events bronchospasm and coronary arteriospasm using a retrospective pharmacovigilance signal analysis was carried out. Methods: Food and Drug Administration’s Adverse Event Reporting System database was used to run disproportionality analyses to investigate the potential association of sugammadex with bronchospasm or coronary arteriospasm. In this analysis we report the adverse event signal using frequentist methods of Relative reporting ratio (RRR), proportional reporting ratio (PRR), reporting odds ratio (ROR) and the Bayesian based Information Component metric. Results: A statistically significant disproportionality signal is found between sugammadex and bronchospasm ( n = 44; chi-squared = 2993.87; PRR = 71.95 [95% CI: 54.00–95.85]) and sugammadex and coronary arteriospasm ( n = 6; chi-squared = 209.39; PRR = 43.82 [95% CI: 19.73–97.33]) as per Evans criteria. Both statistically significant disproportionality signals persisted when stratified by gender. Based upon dynamic cumulative PRR graph, the PRR value has steadily increased and the 95% CI narrowed since December 2012. Conclusion: The results of the pharmacovigilance analysis highlight a statistically significant disproportionality signal between sugammadex usage and bronchospasm and coronary arteriospasm adverse events. Physicians need to be aware of these adverse events when using sugammadex. The results of the pharmacovigilance signal analysis highlight a statistically significant disproportionality signal between sugammadex usage and bronchospasm and coronary arteriospasm adverse events. Physicians need to be aware of these adverse events when using sugammadex.

Purpose Adverse events in chemotherapy clinical trials are assessed and reported by clinicians, yet clinician accuracy in assessing symptoms has been questioned. We compared patient reporting of eight symptoms using a validated instrument, the European Organization for the Research and Treatment of Cancer Quality-of-Life Questionnaire C30 (QLQ-C30 or QLQ) with physicians' reporting of the same symptoms in the study's adverse events log. Patients and Methods Thirty-seven men with metastatic, androgen-independent prostate cancer enrolled onto a phase II trial of weekly calcitriol and docetaxel completed the QLQ every 4 weeks for up to 28 weeks. A patient-reported symptom was defined as an increase in a QLQ symptom score by at least 10 points (0 to 100 scale), sustained for at least 4 weeks. A physician-reported symptom was considered present if it was ever documented in the adverse event log. Results Forty-nine (new or worsened) symptoms were detected by both physician and QLQ, 48 symptoms were detected by the physician alone, and 55 symptoms were detected by the QLQ alone. They agreed on the absence of a symptom in 102 instances of 254 possible opportunities. Their uncorrected agreement was 59.4%, but Cohen's κ, a coefficient of agreement that corrects for chance, was 0.15, indicating only slight agreement. Using the QLQ as the standard, overall physician sensitivity and specificity was 47% and 68%, respectively, although it varied considerably among symptoms. Conclusion Even in a tightly controlled clinical trial, physician reporting was neither sensitive nor specific in detecting common chemotherapy adverse effects. Tools for collecting patient-reported adverse event data in chemotherapy clinical trials should be developed.

Background: In spite of the widespread performance of intra-articular zygapophyseal joint (IAZJ) injections, we know of no systematic analysis to date that examines the risks and types of adverse events when IAZJ injections are performed. Objective: To describe the type, incidence, and factors contributing to adverse events associated with fluoroscopically guided IAZJ injections. Study Design: A retrospective, cohort study of English-speaking adults aged 18 – 90 years who underwent fluoroscopically guided IAZJ injections between March 8, 2004, and April 19, 2007. Following IAZJ injections, 3 senior researchers recorded the presence and type of adverse events. The relationship of adverse events with age, gender, fluoroscopy time, vital signs, and trainee presence was analyzed with Fisher’s exact or Wilcoxon rank sum 2-sided tests. Frequency of immediate (during or immediately after the procedure) or delayed (within 24 – 72 hours following the procedure) adverse events. Setting: Tertiary, academic, outpatient physical medicine and rehabilitation interventional spine clinic. Results: One hundred ninety-one patients (111 men) underwent 239 procedures. The mean and standard deviation (SD) of subject age was 56.4 (16.6) years ranging from 20 to 89. The mean and SD of pre-procedure 11-point Visual Analog Pain Scale was 5.5 (2.2) ranging from 0 to 10, and for post-procedure was 2.6 (2.6) ranging from 0 to 10. Trainees were involved in 52.3% of procedures. Reported immediate adverse events were vasovagal reaction (3.8%, n = 9) and steroid clogged needle (0.4%, n = 1). Follow-up data were available for 185/239 procedures (77.4%). There were 35 adverse events reported at mean follow-up interval of 1.8 days, of which the most frequent were injection site soreness (6.0%, n = 11), pain exacerbation (4.3%, n = 8), sleeplessness (2.2%, n = 4), and transient headache (1.6%, n = 3). Patient gender, age, trainee involvement, pre-procedural pain score, systolic or diastolic blood pressure, pulse, hemoglobin saturation as measured by pulse oximetry, volume of corticosteroid injected, and duration of fluoroscopy were not found to have a significant effect on immediate or delayed adverse events. Limitations: This study is limited by a 24- to 72-hour follow-up window, which may have also been too small to capture more delayed complications, and a sample size too small to accurately define the incidence of rare complications. Conclusion: Fluoroscopically guided IAZJ injections have minimal adverse effects. The most common immediate adverse event was vasovagal reaction and most common delayed adverse event was injection site soreness. Key words: Fluoroscopic injection, facet joint, zygapophyseal joint, complications, adverse effects, steroid injection

ABSTRACT Background Adverse events in hospitals are now widely agreed to be a serious problem, annually killing more people than breast cancer or AIDS. Aims: To study incidence of adverse events in admitted patients by current record review. Aims To study incidence of adverse events in admitted patients by current record review. Materials and methods A two-staged prospective study for a period of 1 year was carried out. Current records of inpatients were screened for adverse events. The adverse event was categorized as preventable or nonpreventable on the basis of World Health Organization (WHO) set confidence score of preventability. Results A total of 3150 patients were screened, among which 488 (15.5%) patients were screened positive for having adverse event. Readmission during last 12 months to any given healthcare for the same health condition (32.79%) was the most common adverse event seen. Hospital acquired infection/sepsis (26.64%) was the second most common adverse event seen. The 78% of adverse events presented with untoward outcome among which 81.8% of adverse events resulted in admission in wards, 4.33% adverse events were associated with death, 23.4% adverse events were associated with disability at discharge and 35.5% adverse events were associated with prolonged stay. A total of 67.4% of studied adverse events showed signs of healthcare team responsible for causing adverse events, among which 76.8% of adverse events occurred outside SKIMS before the index admission. A total of 71.3% of adverse events were categorized preventable. Conclusion Hospital acquired infection was found responsible for prolonged stay of the patients. Proper referral policy must be followed by the department of health services. How to cite this article Mirza M, Jan FA, Mumtaz SH, Sofi FA, Wani RA.
