Association of medication errors with drug classifications, clinical units, and consequence of errors: Are they related?

Drug Therapy Problems Identified by Clinical Pharmacists at a General Surgery Ward of an Academic Referral Hospital in Jordan

Introduction

Drug therapy problems (DTPs) continuously occur in hospitalized patients. This study aims to emphasize the role of clinical pharmacists in evaluating the DTP's frequencies, causes, severity ratings, and contributing factors at a general surgery ward in Jordan.

Methods

This prospective observational study was conducted at one of the major teaching and referral hospitals in Jordan. Data were collected through clinical pharmacist reviews of paper and electronic medical records as well as patient interviews. DTPs were identified using Cipolle's classification system and rated for severity on a scale of 10. Multiple linear regression was performed to identify factors contributing to DTPs. Drug classes primarily associated with DTPs were specified.

Results

During enrollment, a total of 80 patients were recruited in this study. The mean age of the enrolled patients was 52.35 ± 14.82 years, and 49 (61.25%) of them were males. Within the study period, 192 DTPs were identified by clinical pharmacists in 87.5%of the total recruited patients. The mean number of DTPs per patient was 2.40 ± 1.83. The most common categories of DTPs were "needs additional therapy" 46 (23.96%), "unnecessary drug therapy" 45 (23.44%), and "dosage too low" 39 (20.31%). Of the total DTPs, 127 (66.15%) were rated as severe. Multiple linear regression revealed that patients' length of hospital stay and the number of current medications had a statistically significant effect on the number of DTPs identified during hospitalization. Endocrine and metabolic drugs 51 (26.56%) and cardiovascular drugs 36 (18.75%) were the most frequent classes of drugs contributing to DTPs.

Conclusion

DTPs are common in the general surgery ward. Clinical pharmacists can provide medication reviews for surgical patients to identify DTPs and rate their severities. Detecting risk factors for DTPs and the most common drug classes associated with them can assist in decision-making relevant to reducing DTPs in the surgical ward.

Meta-Analysis of Medication Administration Errors in African Hospitals

ABSTRACT

The incidence of medication administration errors (MAEs) and associated patient harm continue to plague hospitals worldwide. Moreover, there is a lack of evidence to address this problem, especially in Africa. This research synthesis was intended to provide current evidence to decrease the incidence of MAEs in Africa. Standardized search criteria were used to identify primary studies that reported the incidence and/or predictors of MAEs in Africa. Included studies met specifications and were validated with a quality-appraisal tool. The pooled incidence of MAEs in African hospitals was estimated to be 0.56 (CI: 0.4324-0.6770) with a 0.13-0.93 prediction interval. The primary estimates were highly heterogeneous. Most MAEs are explained by system failure and patient factors. The contribution of system factors can be minimized through adequate and ongoing training of nurses on the aspects of safe medication administration. In addition, ensuring the availability of drug use guidelines in hospitals, and minimizing disruptions during the medication process can decrease the incidence of MAEs in Africa.

Determination of pain experienced by children during intravenous bolus treatments and its causes

OBJECTIVE

The present study aimed to determine the pain experienced by children during intravenous bolus treatment and to identify what causes it.

METHOD

In the first stage of the study, the first 40 observations were performed by two researchers. The study was continued by a single observer after the Kappa test was performed. In this study, 101 drug treatments were administered by intravenous bolus in patients aged between 1 month and 6 years. The pain experienced during treatment was assessed using pain scales according to the age group the patient was in.

RESULTS

Pain was observed in 63.4% (n = 64) of the treatments. There was a significant relationship between the type of medication administered and pain experienced during drug administration. There was also a significant correlation between the age of the children and their pain experiences. Given the location of the catheter, there was no significant difference among the children who experienced pain during intravenous treatment.

CONCLUSION

Intravenous drug therapy may cause pain in children. To minimize such pain, it is recommended to determine the drugs that cause pain during intravenous treatment and to develop application protocols to minimize pain caused by these drugs.

Antimicrobial residual drug error in the intensive care unit; a single blinded prospective observational study

OBJECTIVE

To determine the percentage of drug remaining in discarded antibiotic vials after use.

DESIGN

Blinded prospective observational trial.

SETTING

26-bed Australian metropolitan tertiary referral intensive care unit.

MAIN OUTCOME MEASURES

Percentage of labelled dose remaining in the vial after discard.

METHOD

Discarded antibiotic vials collected over a 7-day period in an adult intensive care unit were analysed. Each collected vial had any drug remnant washed out and made up to a known volume. A 1 ml aliquot of each vials washings was analysed using high performance liquid chromatography. From this concentration, the percentage of the drug remaining in the vial after discard was calculated. Additionally, each vial was weighed before and after washing to determine the weight of the remnant in each vial.

RESULTS

A total of 311 vials comprising of 11 different drugs and 14 individual vial types were collected. The median residual drug error across all vials was 3.7 %. The drug with the highest median was piperacillin at 6.1 % (IQR 4.3) and the lowest was amoxicillin 0.2 % (IQR 0.1). The single highest value for a given vial was vancomycin (500 mg) with 33.2 % and the lowest for a given vial was 0.1 % amoxicillin (1 g). These two drugs also exhibited the greatest range between the maximum and minimum value for any drug being 32 % and 0.9 % respectively.

CONCLUSIONS

Our study shows that up to a third of the intended dose may fail to reach the patient, highlighting a significant factor in the administration of antibiotics to the critically ill population.

IMPLICATIONS FOR CLINICAL PRACTICE

Residual drug often remains in antibiotic vials meaning that drug is not reaching the patient. There is considerable variation in the method by which medications are reconstituted in clinical settings. Two person checks should be completed after reconstitution in order to ensure that the medication is fully reconstituted and extracted from the vial.

Assessment and analysis of outpatient medication errors related to pediatric prescriptions

BACKGROUND

Medication errors are the errors that impact the efficacy and safety of the therapy. The impact of medication errors is higher for certain subjects, such as pediatrics, who require more attention. Hence, the current study aimed to investigate the types and frequency of outpatient medication errors of pediatric subjects related to different prescription types.

METHODS

A cross-sectional study was carried in several community pharmacies to record the medication errors found in outpatient pediatric prescriptions by gathering data from the outpatient prescriptions besides direct counseling with the subjects and their parents. Many medical resources (disease and drug-related) were used for checking the different aspects of medication errors. The data collection process included a preprepared sheet containing several items representing the medication errors in addition to a counseling session. Data were expressed as percentages and compared through the Chi-square test for results of handwritten and computerized prescriptions.

RESULTS

752 outpatient pediatric prescriptions were recruited in the study as they involve medication errors. Among the highest percentage of medication errors was the absence of essential data in the prescription, such as diagnosis, age, and weight. The duration of the therapy and contraindication for some of the prescribed medications were among the highest recorded errors. Among the critical errors were the drug interaction and drug duplication that directly affect the drug's efficacy and safety. There was a significant difference between computerized and handwritten prescriptions regarding the number of medication errors related to each type.

CONCLUSION

Medication errors related to outpatient pediatric prescriptions vary from one to another prescription with predominant errors that influence the therapy's safety or efficacy. The role of patient counseling and prescription checking is critical for improving patient therapy.

Medication Without Harm: Developing optimal medication error reporting systems

Medication errors are amongst the most frequently occurring health care related incidents and have the potential to lead to life-threatening harm to patients. An incident reporting system is a traditional approach to improvement of patient safety and entails the retrieval of information from incident reports. This not only provides a better understanding of causes and contributing factors but also enables the collection of data on the severity of incidents, system deficiencies and the role of human factors in safety incidents. Medication error reporting systems are often developed as a part of larger incident reporting systems which deal with other types of incidents. Although a rise in the prevalence of medication errors has led to an increased demand for medication error reporting, little is known about characteristics and limitations of medication error reporting systems. The authors broach the subject of medication error reporting systems and propose a more robust and standardized approach.

Psychometric design and validation of a tool to assess the medication administration process through simulation in undergraduate nursing students

BACKGROUND

Medication errors account for 38% of adverse events reported among undergraduate nursing students. Simulation provides training for nursing students in the medication administration process. However, there is a lack of reliable and valid instruments to measure its assessment.

OBJECTIVES

To design and validate a new tool (MEDICORRECT) to assess undergraduate nursing students in the medication administration process using a high-fidelity simulation scenario.

DESIGN AND METHODS

Study participants were fourth year undergraduate nursing students at the University of Barcelona. Phase 1 consisted of tool design and drafting, and content validity and feasibility analyses. Phase 2 covered construct validity and interrater reliability. A factor analysis was conducted, involving a principal component analysis and varimax rotation.

FINDINGS

Of 21 initial items, 11 were eliminated because of low content validity ratio, 4 of which assessed cognitive skills such as administering the right medicine at the right dose, which were impossible to observe in the simulation scenario. The final version of MEDICORRECT contained 10 items. The exploratory factor analysis identified a four-factorial model explaining 67.3% of the variance. Interrater agreement measured with Kappa was greater than 0.70 for 80% of items.

CONCLUSIONS

The 10 items in MEDICORRECT are relevant and feasible, have suitable psychometric properties and reflect the practical skills identified in the medication administration process. The tool excludes cognitive skills, which should be included and assessed during prebriefing.

Medication errors and risk areas in a critical care unit

AIMS

The aim of this study was to identify the main medication errors, their causality and the highest risk areas in critical care.

DESIGN

A descriptive, longitudinal and retrospective study.

METHODS

We performed a systematic analysis of the prescription, transcription and administration records of 2,634 dose units of medications that were administered to a total of 87 critically ill patients during 2018.

RESULTS

Final results have shown important medication errors and a high number of significant drug interactions; prescription phase had the highest mistake rate (71%) and cause of errors (68%); transcription stage had a more variable error typology. A significant correlation was observed between the presence of causes and contributing factors to error during the prescription and the commission of errors during the nurse transcription, being the main risk areas the time of antibiotic administration, dilution errors, concentration and speed of administration of high-risk medications and the technique used for nasogastric tube drug administration.

CONCLUSION

In critical care, an intolerable number of medication errors are still committed, placing the origin of many of them in the causality and contributing factors identified in the prescription stage.

IMPACT

The origin of many of the medication errors and most interactions is in the prescription stage, being the nurse transcription (nurse intervention) in an important filter that prevents a considerable number of errors from finally reaching the patient. The schedule of administration of time-dependent antibiotics, high-risk medications and the technique of administering medications through a nasogastric tube are important risk areas for the commission of medication errors.

Hospital Nurses' Perceived Patient Safety Culture and Adverse Nurse Outcomes in Korea

BACKGROUND

Hospital nurses are likely to be the first to observe patient safety issues in clinical settings, and thus it is important to include their views on patient safety culture. However, there are few studies addressing the influence of nurses' perceived patient safety culture on adverse nurse outcomes as quality of care.

PURPOSE

This study was to identify the relationship between nurses' perceptions of patient safety culture and adverse nurse outcomes in Korea.

METHODS

This cross-sectional study was included 299 nurses at two tertiary hospitals. Hierarchical linear regression was conducted to examine the impact of patient safety culture on adverse nurse outcomes among hospital nurses.

RESULTS

The mean score of patient safety culture and adverse nurse outcomes were 3.50 out of 5 points and 3.07 out of 4 points respectively. In hierarchical linear regression, hospital work environment, the attitude of supervisor/manager, and hospital climate/culture of patient safety culture predicted adverse nurse outcomes after adjusting for general characteristics.

CONCLUSIONS

It is crucial for healthcare facilities to assess or evaluate their current patient safety culture perceptions on a regular basis. Furthermore, provision workshops and staff training on changing behaviors and perceptions regarding patient safety activities can improve nursing performance in clinical settings.

Medication errors in prescription and administration in critically ill patients

AIM

To determine the prevalence and magnitude of medication errors and their association with patients' sociodemographic and clinical characteristics and nurses' work conditions.

DESIGN

An observational, analytical, cross-sectional and ambispective study was conducted in critically ill adult patients.

METHODS

Data concerning prescription errors were collected retrospectively from medical records and administration errors were identified through direct observation of nurses during drug administration. Those data were collected between April and July 2015.

RESULTS

A total of 650 prescription errors were identified for 961 drugs in 90 patients (mean error 7[SD 4.1] per patient) and prevalence of 47.1% (95% CI 44-50). The most frequent error was omission of the prescribed medication. Intensive care unit stay was a risk factor associated with omission error (OR 2.14; 1.46-3.14: p < .01). A total of 294 administration errors were identified for 249 drugs in 52 patients (mean error 6 [SD 6.7] per patient) and prevalence of 73.5% (95% CI 68-79). The most frequent error was interruption during drug administration. Admission to the intensive care unit (OR 0.37; 0.21-0.66: p < .01), nurses' morning shift (OR 2.15; 1.10-4.18: p = .02) and workload perception (OR 3.64; 2.09-6.35: p < .01) were risk factors associated with interruption.

CONCLUSIONS

Medication errors in prescription and administration were frequent. Timely detection of errors and promotion of a medication safety culture are necessary to reduce them and ensure the quality of care in critically ill patients.

IMPACT

Medication errors occur frequently in the intensive care unit but are not always identified. Due to the vulnerability of seriously ill patients and the specialized care they require, an error can result in serious adverse events. The study shows that medication errors in prescription and administration are recurrent but preventable. These findings contribute to promote awareness in the proper use of medications and guarantee the quality of nursing care.

Medication errors and drug knowledge gaps among critical-care nurses: a mixed multi-method study

BACKGROUND

Medication errors are a serious and complex problem in clinical practice, especially in intensive care units whose patients can suffer potentially very serious consequences because of the critical nature of their diseases and the pharmacotherapy programs implemented in these patients. The origins of these errors discussed in the literature are wide-ranging, although far-reaching variables are of particular special interest to those involved in training nurses. The main objective of this research was to study if the level of knowledge that critical-care nurses have about the use and administration of medications is related to the most common medication errors.

METHODS

This was a mixed (multi-method) study with three phases that combined quantitative and qualitative techniques. In phase 1 patient medical records were reviewed; phase 2 consisted of an interview with a focus group; and an ad hoc questionnaire was carried out in phase 3.

RESULTS

The global medication error index was 1.93%. The main risk areas were errors in the interval of administration of antibiotics (8.15% error rate); high-risk medication dilution, concentration, and infusion-rate errors (2.94% error rate); and errors in the administration of medications via nasogastric tubes (11.16% error rate).

CONCLUSIONS

Nurses have a low level of knowledge of the drugs they use the most and with which a greater number of medication errors are committed in the ICU.

Factors related to medication errors in the preparation and administration of intravenous medication in the hospital environment

BACKGROUND

Medication errors have long been associated with low-quality medical care services and significant additional medical costs.

OBJECTIVE

The aim of this study was to culturally adapt and validate the questionnaire on knowledge, attitudes and behaviors in the administration of intravenous medication, as well as to explore these factors in a hospital setting.

METHODS

The study was divided into two phases: 1) validation and cross-cultural adaptation, and 2) cross-sectional study. A total of 276 hospital-based nursing professionals participated in the study.

RESULTS

A Cronbach's alpha value of 0.849 was found, indicating good internal consistency. In the multivariate analysis, statistically significant differences were found between knowledge and attitudes, demonstrating that having greater suitable knowledge correlates with having a more positive attitude. It was also discovered that having a positive attitude as well as the necessary knowledge increases the possibility of engaging in adequate behaviors.

CONCLUSIONS

The knowledge, attitudes and behavior questionnaire has a satisfactory internal consistency in order to be applied to the Spanish context. Implications for nursing management: Knowledge acquisition and positive attitude are both factors which promote adequate behavior, which in turn seems to have an impact on medication errors prevention. Health institutions must encourage continuous education for their employees.

Personalized Anticoagulation: Optimizing Warfarin Management Using Genetics and Simulated Clinical Trials

BACKGROUND

Clinical trials testing pharmacogenomic-guided warfarin dosing for patients with atrial fibrillation have demonstrated conflicting results. Non-vitamin K antagonist oral anticoagulants are expensive and contraindicated for several conditions. A strategy optimizing anticoagulant selection remains an unmet clinical need.

METHODS AND RESULTS

Characteristics from 14 206 patients with atrial fibrillation were integrated into a validated warfarin clinical trial simulation framework using iterative Bayesian network modeling and a pharmacokinetic-pharmacodynamic model. Individual dose-response for patients was simulated for 5 warfarin protocols-a fixed-dose protocol, a clinically guided protocol, and 3 increasingly complex pharmacogenomic-guided protocols. For each protocol, a complexity score was calculated using the variables predicting warfarin dose and the number of predefined international normalized ratio (INR) thresholds for each adjusted dose. Study outcomes included optimal time in therapeutic range ≥65% and clinical events. A combination of age and genotype identified different optimal protocols for various subpopulations. A fixed-dose protocol provided well-controlled INR only in normal responders ≥65, whereas for normal responders <65 years old, a clinically guided protocol was necessary to achieve well-controlled INR. Sensitive responders ≥65 and <65 and highly sensitive responders ≥65 years old required pharmacogenomic-guided protocols to achieve well-controlled INR. However, highly sensitive responders <65 years old did not achieve well-controlled INR and had higher associated clinical events rates than other subpopulations.

CONCLUSIONS

Under the assumptions of this simulation, patients with atrial fibrillation can be triaged to an optimal warfarin therapy protocol by age and genotype. Clinicians should consider alternative anticoagulation therapy for patients with suboptimal outcomes under any warfarin protocol.
