Exploring Nurses' Perceptions of Medication Error Risk Factors: Findings From a Sequential Qualitative Study.

A focus group study was conducted to explore nurses' perceptions of medication administration error associated factors in two medical wards of a tertiary hospital. Nurses were invited to participate in focus group discussions. Thematic analysis was employed and identified four themes: professional practice environment related factors, person-related factors, drug-related factors, and processes and procedures. Staffing, interruptions, system failures, insufficient leadership, and patient acuity were perceived as risk factors for medication errors. The findings of this study complement the findings of an observational study which investigated medication administration errors in the same setting. Although some findings were similar, important risk factors were identified only through focus group discussions with nurses. Nurses' perceptions of factors influencing medication administration errors provide important considerations in addressing factors that contribute to errors and for improving patient safety.

Observational Evidence of the Prevalence and Association of Polypharmacy and Drug Administration Errors in Hospitalized Adult Patients.

Objective To describe the prevalence of polypharmacy and medication administration errors (MAEs) in adult inpatients and explore the association between polypharmacy and MAEs. Polypharmacy and MAEs are common phenomena in hospital settings. Different MAE contributing factors have been suggested by previous studies. Polypharmacy, however, is not always assessed by studies exploring medication error risk factors, and it may deserve further attention. Methods This was a descriptive observational study. The medication administration process in two adult medical wards of a tertiary hospital was recorded by two observers, with parallel review of patients' medication records. Any deviation from prescriber's order, manufacturers' administration instructions, or relevant institutional policies were recorded as errors. Chi square and regression analysis were used to explore associations between polypharmacy and MAEs. Results Six hundred sixty-five medication administrations were observed. The mean number of drugs prescribed per patient was 8.7. Most inpatients were prescribed more than 5 drugs (92.6%). Almost half of the inpatients were prescribed more than 9 drugs (45.1%) and some more than 12 drugs (22.6%). In total, 2,371 errors were detected, and the mean number of errors per administration was 3.5. When patients received more than 9 (the odds ratio is 1.57, [95%] CI 1.08-2.27; P = 0.02) or more than 12 (the odds ratio is 1.53, [95%] CI 1.04-2.30; P = 0.04) drugs, the occurrence of a higher number of errors per administration was significantly increased. Conclusion Polypharmacy is common in adult medical wards and can be associated with the occurrence of a higher number of MAEs. Future interventions aiming for the prevention of MAEs should consider addressing polypharmacy by improving prescribing practices and optimizing pharmacotherapy.

Omissions and Deviations From Safe Drug Administration Guidelines in 2 Medical Wards and Risk Factors: Findings From an Observational Study.

OBJECTIVES: This study aimed to record the type and frequency of errors, with an emphasis on omissions, during administration of medicines to inpatients and to investigate associated factors. METHODS: This was a descriptive observational study. The medication process in 2 medical wards was observed by 2 observers using a structured observation form. χ2 Test, Kruskal-Wallis test, and regression analysis were used to explore associations between factors and errors. RESULTS: From the 665 administrations observed, a total of 2371 errors were detected from which 81.2% were omissions and 18.8% were errors of commission. Omissions in the infection prevention guidelines (46.6%) and in the 5 rights of medication safety principles (35.8%) were a predominant finding. In particular, omitting to hand wash before administering a drug (98.4%), omitting to disinfect the site of injection (37.7%), and omitting to confirm the patient's name (74.4%) were the 3 most frequently observed omissions. Documentation errors (13.1%) and administration method errors (4.5%) were also detected. Regression analysis has shown that the therapeutic class of the drug administered and the number of medicines taken per patient were the 2 factors with a statistical significance that increased the risk of a higher number of errors being detected. CONCLUSIONS: Errors during drug administration are still common in clinical practice, with omissions being the most common type of error. In particular, omissions in the basic infection and safety regulations seem to be a very common problem. The risk of a higher number of errors being made is increased when a cardiovascular drug is administered and when the number of medicines administered per patient is increased.

Tape lures swell bycatch on a Mediterranean island harbouring illegal bird trapping.

Mediterranean islands provide shelter and sustenance for millions of migrating birds each year. Humans have historically exploited bird migration through hunting. In Cyprus, trapping birds during their migratory peak is considered a tradition, but has long been against the law. Illegal bird trapping is lucrative, however, with trappers using tape lures that broadcast birdsong to increase capture rates. It results in the slaughter of millions of birds each year. Yet, scientific studies quantifying capture rates of target and nontarget species using methods employed by trappers are lacking. Here, we show using playback experiments that tape lures lead to an order of magnitude greater capture rates of target species, but also significantly increase bycatch, which may include species of conservation concern. Conservation efforts focusing on minimizing illegal bird killing should also consider tape lures and their contribution to the overall impact of trapping on avian populations.
