Medication errors among Iranian emergency nurses: A systematic review

Medication errors in emergency departments: a systematic review and meta-analysis of prevalence and severity

BACKGROUND

Medication errors significantly compromise patient safety in emergency departments. Although previous studies have investigated the prevalence of these errors in this setting, results have varied widely.

AIM

The aim was to report pooled data on the prevalence and severity of medication errors in emergency departments, as well as the proportion of patients affected by these errors.

METHOD

Systematic searches were conducted in Embase, PubMed, and the Cochrane Library from database inception until June 2023. Studies provided numerical data on medication errors within emergency departments were eligible for inclusion. Random-effects meta-analysis was employed to pool the prevalence of medication errors, the proportion of patients experiencing these errors, and the error severity levels. Heterogeneity among studies was assessed using the I2 statistic and Cochran's Q test.

RESULTS

Twenty-four studies met the inclusion criteria. The meta-analysis gave a pooled prevalence of medication errors in emergency departments of 22.6% (95% Confidence Interval [CI] 19.2-25.9%, I2 = 99.9%, p < 0.001). The estimated proportion of patients experiencing medication errors was 36.3% (95% CI 28.3-44.3%, I2 = 99.8%, p < 0.001). Of these errors, 42.6% (95% CI 5.0-80.1%) were potentially harmful but not life-threatening, while no-harm errors accounted for 57.3% (95% CI 14.1-100.0%).

CONCLUSION

The prevalence of medication errors, particularly those potentially harmful, underscores potential safety issues in emergency departments. It is imperative to develop and implement effective interventions aimed at reducing medication errors and enhancing patient safety in this setting.

The factors influencing patient safety management as perceived by emergency department nurses: A qualitative study

AIM

One of the most important, unpredictable and stressful areas in hospitals is the emergency department (ED) where seconds are crucial for providing immediate care and saving the patients' lives. Therefore, the present study aimed to identify the factors which impact the patient safety management as perceived by the ED nurses in Southern Iran.

DESIGN

This is a qualitative, descriptive study.

METHODS

The participants were 23 ED nurses selected via purposeful sampling who were asked to take part in an interview. Data were collected using semi-structured, individual, in-depth interviews and analysed via content analysis.

RESULTS

Analysis of the qualitative data yielded 4 themes and 12 subthemes. The four main themes were: negligence of safety standards and standard precautions, disregard of ethical principles, professional challenges and inefficient organizational management.

Frequency and influential factors on occurrence of medical errors: A three-year cross-sectional study

BACKGROUND

Despite efforts to improve patient safety, medical errors (MEs) continue to recur. Proper utilization of reported MEs can be effective in preventing their recurrence. This study investigated the errors reported in 3 years and examined the factors affecting them.

MATERIALS AND METHODS

This descriptive analytical study was conducted using the errors reported in 20 hospitals under the auspices of one of Iran's medical universities from 2018 to 2020. All reported errors were investigated by an expert panel.

RESULTS

In total, 6584 reported errors were grouped into four main categories based on the type of error. The highest reported errors were related to the management and treatment procedures. Analyses of the factors influencing medical errors revealed that 15 factors affected the occurrence of errors. An increasing trend of error was found in 9 of the 15 identified factors. Incorrect documenting of the physician's order in the nursing Kardex and noncompliance with the patient identification guide were the highest with 16.03 and 15.47%, respectively.

CONCLUSION

The most identified factor was the incorrect registration of the physician's prescription on the nursing card; therefore, it seems that the use of computerized physician order entry should be considered. Furthermore, the mere existence and training of patient safety guides cannot help prevent errors. Not only should the underlying causes of errors be carefully identified and investigated but it also requires serious determination to follow the patient's safety instructions from the highest to the lowest levels of the health system.

Recurrence of medical errors despite years of preventive measures: A grounded theory study

BACKGROUND

Despite great efforts to improve patient safety, serious preventable medical errors continue to occur. Accurate rooting causes of error recurrence are essential for reviewing methods to prevent them. This study aimed to identify the main causes of the recurrence of medical errors despite their previous occurrence.

MATERIALS AND METHODS

This qualitative study was performed using the grounded theory method, with theoretical sampling from April to July 2021, through semi-structured interviews with 25 experts and treatment staff of hospitals under the auspices of four universities of medical sciences in Iran.

RESULTS

Four main parts were identified: 1) primary and secondary factors leading to the occurrence of errors, 2) error prevention policies, 3) causes of error repetition, and 4) contextual factors.

CONCLUSION

The attention, seriousness, and commitment of health system managers, from top to bottom, to patient safety are essential for preventing error recurrence. The institutionalization of patient safety education from universities and attention to individual, social, and cultural factors should also be given serious attention.

Medication Errors among Iranian Intensive Care Nurses: A Systematic Review

Background

Medication Error (ME) is a major patient safety concern in Intensive Care Units (ICUs). Critical care nurses play a crucial role in the safe administration of medication. This study was conducted to comprehensively review the literature concerning the prevalence of ME and associated factors and outcomes in Iranian ICU nurses.

Materials and Methods

An extensive search of the literature was carried in international databases including PubMed, Web of Science, Scopus, and Google Scholar, as well as Persian databases such as Magiran and Scientific Information Database (SID) using ME-related keywords and the Persian equivalent of these keywords, from the first article written in this field to artcles published on March 30, 2021. The appraisal tool (AXIS tool) was used to assess the quality of the included studies.

Results

Fifteen studies were included in this systematic review. The prevalence of MEs made by ICU nurses was 53.34%. The most common types of MEs were wrong infusion rate (14.12%), unauthorized medication (11.76%), and wrong time (8.49%) errors, respectively. MEs occurred more frequently in morning work shifts (44.44%). MEs happened more frequently for heparin, vancomycin, ranitidine, and amikacin. The most important influential factor in the occurrence of MEs in ICUs was management and human factors.

Conclusions

The prevalence of MEs made by Iranian ICU nurses is high. Therefore, nurse managers and policymakers should develop appropriate strategies, including training programs, to reduce the occurrence of MEs made by nurses in ICUs.

Intravenous medication errors in the emergency department, knowledge, tendency to make errors and affecting factors: An observational study

BACKGROUND

Intravenous medication errors are common in hospital settings particularly emergency department. This study aimed to determine intravenous medication preparation and administration errors, contributing factors, tendency towards making errors and knowledge level of emergency department healthcare workers.

METHODS

A cross-sectional study using a structured, direct observation method was conducted. It was conducted with 23 emergency healthcare workers working in the emergency department of a university hospital in Turkey. Data were collected by questionnaires: Knowledge Test on Intravenous Medication Administration, Intravenous Drug Administration Standard Observation Form, Drug and Transfusion Administration Sub-Dimension scale, Perceived Stress Scale and Pittsburgh Sleep Quality Index.

RESULTS

It was determined that the knowledge level of the emergency healthcare workers about intravenous medication administration was moderate, and the tendency mistakes regarding drug and transfusion applications was very low. There was no relationship between education level, years of work, years of work in the emergency department, perceived stress level and sleep quality, and the tendency of making mistakes in drug and transfusion applications.

CONCLUSION

It is important for patient safety to prevent medication errors by determining the factors affecting intravenous medication administration, tendency to make mistakes and knowledge levels, which are frequently used in emergency department.

Predictors of patient safety competency among emergency nurses in Iran: a cross-sectional correlational study

AIMS

This study aimed to assess predictors of patient safety competency among emergency nurses.

BACKGROUND

The role of emergency nurses is to provide high-quality health care to patients and ensure their safety. The patient safety competency includes the absence of unnecessary or potential harm when providing health care to patients. In providing health care, effective teamwork can affect patient safety and outcomes. Psychological safety is essential to effective teamwork. Psychological safety allows health care workers to accept the interpersonal risks needed to perform effective teamwork and maintain patient safety.

METHODS

This study was cross-sectional correlational research. Using convenience sampling methods, 254 emergency department nurses from five educational hospitals were enrolled in the study. Patient Safety in Nursing Education Questionnaire was used to measure the patient safety competency, the teamwork questionnaire to examine the teamwork, and Edmondson psychological safety questionnaire was used to measure psychological safety. Descriptive statistics, t-test, one-way analysis of variance (ANOVA), Pearson's r correlation coefficient, and multivariate stepwise linear regression analysis were applied using SPSS 14.0.

RESULTS

Participants' mean patient safety competency score was 2.97 (1-4). Between 18 independent variables evaluated in the multiple regression analysis, seven had a significant effect on the patient safety competency of emergency nurses (R²: 0.39, p < .001).

CONCLUSIONS

The patient safety competency of emergency department nurses was primarily related to the structure and leadership of the team and secondary to psychological safety and experience in patient safety activity. The results demonstrated that policymakers and hospital managers should improve and enhance team structure and leadership via supervision and cooperation with the nursing staff. The development of training programs in patient safety activities, improvement, and increase of psychological safety at the levels of the nursing units is essential to increase patient safety competencies in the emergency nursing program.

Analysis of contributory factors to incidents related to medication assistance for residents taking medicines in residential care homes for the elderly: a qualitative interview survey with care home staff

Background

In Japan, staff who are not doctors or nurses can assist the elderly in residential care facilities to take their pre-packaged medicines. Therefore, there is a potential risk of incidents specific to staffs. The aim of this study was to clarify the causes of incidents related to medication assistance by staff in residential care facilities.

Method

Semi-structured interviews with staff involved in medication incidents in long-term care facilities, focusing on how and why each incident happened, were conducted. The interview covered basic information about the subject and resident, the circumstances under which the incident had occurred, contributing factors, and countermeasures put in place. Verbatim transcripts of the interviews were prepared. Based on thematic analysis, codes and themes were created.

Results

Twelve subjects participated in this study. All subjects were staffs (not doctors or nurses) in long-term care facilities. All incidents covered in this study were incidents in which the wrong resident was given the medication. The incidents arose because of “not following procedures”, such as lack of “self-check of residents’ faces/residents’ names/residents’ medicine envelopes” or “double-check with other staff” or “using a device for medication intake”. Contributory factors were grouped into four categories: individual resident factor items such as “decreased ability to understand their medication” or “refusal to take medicines”, individual staff factor items such as “lack of knowledge related to medication” or “mental burden” or “experience in medication assistance”, team factor items such as “failure to communicate with other staff”, work environment factor items such as “presence of other residents” or “other work besides medication assistance” or “not enough time” or “little understanding of fostering a safety culture at the facility”.

Conclusion

This study identified four categories of contributory factors that may lead to incidents during medication assistance by caregivers for residents of care homes. These findings should be helpful for risk management in residential care facilities where staff usually provide medication assistance. Separation of meal times and medication assistance, and professional review to stagger the timing of administration of residents’ medication may be effective in reducing incidents.
