Risk factors for unintentional medication discrepancies at hospital admission: A matched case-control study

Insight into Risk Factors, Pharmacogenetics/Genomics, and Management of Adverse Drug Reactions in Elderly: A Narrative Review

The European Medicine Agency (EMA) has defined Adverse Drug Reactions (ADRs) as "a noxious and unintended response to a medicine", not including poisoning, accidental, or intentional overdoses. The ADR occurrence differs based on the approach adopted for defining and detecting them, the characteristics of the population under study, and the research setting. ADRs have a significant impact on morbidity and mortality, particularly among older adults, and represent a financial burden for health services. Between 30% and 60% of ADRs might be predictable and preventable, emerging as a result of inappropriate prescription, drug chemistry inherent toxicity, cell-specific drug toxicity, age- and sex-related anomalies in drug absorption, distribution, metabolism, and elimination (ADME), and drug-drug interactions (DDIs) in combination therapies or when a patient is treated with different drugs for concomitant disorders. This is particularly important in chronic diseases which require long-term treatments. Rapid developments in pharmacogenetics/genomics have improved the understanding of ADRs accompanied by more accurate prescriptions and reduction in unnecessary costs. To alleviate the burden of ADRs, especially in the elderly, interventions focused on pharmaceutical principles, such as medication review and reconciliation, should be integrated into a broader assessment of patients' characteristics, needs, and health priorities. Digital health interventions could offer valuable solutions to assist healthcare professionals in identifying inappropriate prescriptions and promoting patient adherence to pharmacotherapies.

Development and implementation of a medication reconciliation during pediatric transitions of care in a public hospital

OBJECTIVES

To generate effective changes in the work processes of an institution, such as hospitals, strategies are needed for the implementation of services. These should be based on the needs of the practice scenario and evidence that may develop programs applied to the routine of health care. This study aimed to implement medication reconciliation (MR) at the transition of care in the pediatric department of a public hospital located in Northeast Brazil.

SETTING

A step-by-step approach was adopted to implement MR in the studied hospital and conducted from March 2019 to December 2019.

PRACTICE INNOVATION

The implementation of MR used the "Model for Improvement" framework. The processes were built and tested in the Plan-Do-Study-Act (PDSA) cycles. Children admitted to the hospital's pediatrics department were included in the study. The objective of the PDSA cycles was to reach 75% of the patients included, with the service performed in at least one transition of care episode.

EVALUATION

This study used the following indicators: number of steps performed, number of discrepancies identified, and resolution of discrepancies. Descriptive statistical analysis was performed for all variables.

RESULTS

In the first cycle, all patients (n = 34) had the best possible medication history (BPMH) completed, and 26.4% went through all the MR stages. Seventy-two discrepancies were identified and 90.3% of them were resolved. In the second cycle, all patients (n = 35) had the BPMH completed, and 20% went through all the stages. A total of 32 discrepancies were identified and 96.8% of them were resolved. In the third cycle, all patients (n = 30) had the BPMH completed, and 56.6% of patients went through all the stages. Twenty-four discrepancies were identified and resolved.

CONCLUSION

The use of the "Model for Improvement" framework effectively contributed to the implementation of the service according to the characteristics of the studied hospital.

Medication discrepancies in transition of care of hospitalised children in Brazil: a multicentric study

OBJECTIVE

To determine the incidence of medication discrepancies in transition points of care of hospitalised children.

DESIGN

A prospective observational multicentre study was carried out between February and August 2019. Data collection consisted of the following steps: sociodemographic data collection, clinical interview with the patient's caregiver, review of patient prescriptions and evaluation of medical records. Medication discrepancies were classified as intentional (documented or undocumented) and unintentional. In addition, discrepancies identified were categorised according to the medication discrepancy taxonomy. Unintentional discrepancies were assessed for potential clinical harm to the patient.

SETTING

Paediatric clinics of four teaching hospitals in Brazil.

PATIENTS

Children aged 1 month-12 years.

FINDINGS

A total of 248 children were included, 77.0% (n=191) patients had at least one intentional discrepancy; 20.2% (n=50) patients had at least one unintended discrepancy and 15.3% (n=38) patients had at least one intentional discrepancy and an unintentional one. The reason for the intentional discrepancy was not documented in 49.6% (n=476) of the cases. The most frequent unintentional discrepancy was medication omission (54.1%; n=66). Low potential to cause discomfort was found in 53 (43.4%) unintentional discrepancies, while 55 (45.1%) had the potential to cause moderate discomfort and 14 (11.5%) could potentially cause severe discomfort.

CONCLUSIONS

Although most medication discrepancies were intentional, the majority of these were not documented by the healthcare professionals. Unintentional discrepancies were often related to medication omission and had a potential risk of causing harm to hospitalised children.

Prevalence of medication discrepancies in pediatric patients transferred between hospital wards

Background Children are more susceptible to harm from medication errors and adverse drug reactions when compared to adults. Such events may occur from medication discrepancies while transitioning patients throughout the healthcare system. Contributing factors include medication discontinuity and lack of information by the healthcare team. Objective To analyze the prevalence of medication discrepancies in transition points of care in a pediatric department. Setting Pediatric department of a public hospital in Northeast Brazil. Method A cross-sectional study was carried out from August 2017 to March 2018. Data collection consisted of the following steps: collection of sociodemographic data, clinical interview with the patient's caregiver, registration of patient prescriptions, and evaluation of medical records. Medication discrepancies were classified as intentional and unintentional. The unintentional medication discrepancies were classified as omission of medication, therapeutic duplicity, and differences in dose, frequency, or route of administration. Main outcomes measure Discrepancy profile identified at admission, internal transfer and hospital discharge. Results Among the 114 patients included in the study, 85 (74.5%) patients had at least one unintentional medication discrepancy, of which 16 (14.0%) patients presented medication discrepancies at hospital admission, 42 (36.8%) patients at internal transfer, and 52 (45.6%) patients during discharge. Omission of medication represented 20 (74.1%) errors at admission, 26 (37.7%) errors at internal transfer, and 80 (100.0%) errors at hospital discharge. Conclusions The main transition points of care where unintentional discrepancies occurred in the studied pediatric department were at internal transfer and hospital discharge, with omission being the most common type of unintentional discrepancy.
