Introduction
Medication-related deaths and adverse effects are mainly due to medication errors [
1]. Drug safety is particularly important in pediatric patients, as they may be at higher risk of harm resulting from errors than adult patients [
2]. Previous studies have uncovered errors at all stages of pediatric medication use, from prescription to administration [
3], in the hospital, outpatient and home setting [
4].
A 2020 meta-analysis by Gates et al. [
4] obtained a rate of medication error in hospitalized children of 15.0 (3.1–49.4) per 100 prescriptions. The authors observed that most medication errors in the hospital setting occurred during prescribing process. In 2019, Glick et al. [
5] found that 38% of parents or legal guardians committed some type of error when administering medication to their children in the first two weeks after discharge. Data from the US National Poison Database System showed a mean annual rate of out-of-hospital medication errors in the decade between 2002 and 2012 of 26.42 per 10,000 children aged under 6 years [
6]. This should be taken as an approximated value because this system only captures cases reported to poison control center. The medication errors without recognition or errors that were noticed but not reported because individuals involved seek information from other sources were not counted.
Although most studies on pediatric medication errors at home focus on dose errors [
5,
7], the literature has shown that parents and/or caregivers also make other mistakes, such as incorrectly preparing or reconstituting the medication [
8,
9] or administering the dose twice [
6]. Berthe-Aucejo et al. [
9] found that among parents and caregivers, risk factors for committing errors when administering medication to pediatric patients included being young, male, and non-native to their country of residence. Higher frequency of errors may also be associated with medical prescriptions that include more than two drugs, and certain types of dosing devices [
10]. According to previous studies, analgesics are most commonly involved in pediatric medication errors at home [
6,
11].
To reduce the occurrence of these errors, it is necessary to promote the safe use of medication at home. One prevention strategy involves medication error reporting systems [
12]; however, as far as we know, no such system exists for the parents or caregivers of pediatric patients [
13]. Currently, there is a great deal of interest in how patients and families can report patient safety events and work with policymakers and healthcare professionals to improve patient safety. In fact, in the United States, as well as in other countries such as Finland and Norway, there are initiatives to create independent agencies that can receive reports on adverse events in patient safety, analyze data, identify patterns of harm risks, investigate, and establish prevention and recommendation strategies to prevent adverse events in the home, with a particular focus on medication errors. This study aims to provide a preliminary understanding of the challenges faced by caregivers of pediatric patients in home care, with a specific focus on medication errors, and to identify potential strategies to prevent and minimize them. The goal is to learn from these experiences and prevent future occurrences of such errors. These and other prevention programs should be based on the needs of the users, i.e. pediatricians and parents or caregivers. Thus, the research question was: what are the perceptions and attitudes of pediatricians and families towards pediatric medication errors at home? This study aims to identify and compare the perceptions and attitudes of pediatricians and those of parents/caregivers regarding pediatric medication errors at home.
Materials and methods
We carried out a cross-sectional survey study spanning the period between November 2019 and March 2021. The study protocol was approved by the Responsible Research Office of Miguel Hernandez University in Elche, Spain (Reference: DPS.MGM.01.19). The patients/participants provided their written informed consent to participate in this study.
Our study included two populations: pediatricians working in public or private healthcare centers in Spain, and parents of children aged 14 years and younger residing in Spain. The inclusion criteria required that all study participants understand the Spanish language, have internet access, participate in the study voluntarily, and sign an informed consent form. Respondents were selected by snowball sampling. Starting with target populations of 12,000 pediatricians working in Spain and 5,000,000 families with children living in Spain, and applying a confidence level of 95% and a margin of error of 8%, we established a minimum required sample size of 149 pediatricians and 151 families.
After performing a literature review and consulting with two pediatricians, we designed a survey for pediatricians and another for families. The family survey underwent a legibility assessment and was initially presented to two families to ensure comprehensibility. The survey for pediatricians included nine multiple-choice questions and one open question (Supplementary Document
1), and the survey for families included 11 open questions and three multiple-choice questions (Supplementary Document
2). Questions on general difficulties faced by parents in caring for their children - like feeding concerns, and symptoms of disease among others-, were included to obtain the initial (spontaneous) opinion of the respondents about the difficulties of medical treatment. The questions in both surveys were grouped into three thematic blocks: difficulties faced by parents in caring for their children, pediatric medication errors at home, and prevention strategies. In addition, the following sociodemographic variables were collected from pediatricians: sex, age, years of experience, specialty, level of care, and Spanish autonomous community of residence; and from parents: sex, age, marital status, educational attainment, Spanish autonomous community of residence, number of children, number of emergency room (ER) visits with their child in the past six months, and number of pediatric primary care visits in the past 6 months.
Both surveys were created using Google Forms, from which the responses could be exported to a spreadsheet for subsequent statistical analysis. Through the link to the form participants could access information on the study (study objective, justification, what the study participation consist and the applicability of the results, i.e. the intention to develop an error reporting system based on the study results), the informed consent form and the survey questions. Pediatricians were invited to participate in this study by email through the contact networks of the research team. The invitation for parents of children under 14 was disseminated on social media. The pediatrician survey was launched in November 2019 and closed in March 2020; the family survey was launched in April 2020 and closed in October 2020.
Data analysis
Answers to open-ended questions were coded and analyzed using the thematic analysis with a deductive approach (number of spontaneous comments from the participants).
We performed a descriptive analysis, obtaining means and standard deviations of the quantitative variables; and frequencies of the qualitative variables. In order to compare the responses to questions that featured in both surveys (pediatricians and parents /caregivers), we applied the Chi-square statistic to contrast the frequencies of qualitative variables and multivariate techniques to measure different associations. P values below 0.05 were considered statistically significant. The statistical analysis was carried out using RStudio version 1.3.1093.
Discussion
The results of this study reveal the perceptions and attitudes of pediatricians and parents with regard to pediatric medication errors in the home setting. Firstly, a series of open questions are asked of parents to find out about the problem situations that occur with their children and how important spontaneous medication errors are for them, followed by a focus on what medication errors in paediatrics are and the importance of designing home-based reporting systems to prevent them. Problems with food/feeding and knowing when to go to the pediatrician were considered more important than problems related to medical treatment. While most pediatricians thought that parents used the internet as their main source of information for resolving doubts related to their children’s health, most parents said they consulted a healthcare professional in such cases. Regarding errors in the home use of pediatric medication, parents’ and caregivers’ lack of knowledge was one of the causes most frequently mentioned by both pediatricians and parents. Most pediatricians said they would recommend a program designed to prevent these errors to the families of their patients.
Among the main difficulties encountered by families in caring for their children is the lack of understanding the nature of the disease and how to manage it properly, difficulty administering medications to their children, either due to dosage problems, storage problems, or problems remembering administration, financial problems or lack of social support [
14‐
16]. Although our results suggest that managing medical treatment is not recognized as a major difficulty. According to families’ perceptions, there are other childcare issues that also require attention, previous studies have found that parents and caregivers make dosing errors [
17]; prepare medications incorrectly [
9]; medicate their children without prior recommendation from a pediatrician, especially to treat fever or coughs and colds [
18]; and have difficulty identifying and managing symptoms (e.g., there are still misconceptions about fever) [
19].
Pediatricians and families seemed to agree that medication errors at home are due to lack of knowledge and lack of information. Previous studies confirmed that parents and caregivers of pediatric patients made errors because they did not understand the treatment instructions [
9,
20] or did not know how to convert between units of measurement [
21] or how to prepare the medicine [
9]. Although dosing errors constitute the type of pediatric medication error most studied and discussed in the scientific literature, only a minority of the families surveyed for this study thought that they made this kind of error when administering medicine to their children. The pediatricians agreed with the published literature [
6] in considering that analgesics and antipyretics constitute the pharmacological group most frequently involved in medication errors at home.
Concerning the sources of information most frequently consulted by families to resolve doubts about their children’s health or medical treatments, a 2011 study conducted in Spain indicated that a high proportion of families consulted the internet [
22]. However, the families who participated in this study said they were more likely to consult a healthcare professional.
As far as we know, there are currently no systems in place for reporting errors in the home use of medication. The pediatricians surveyed for this study said they would recommend an informative intervention program to the families of their patients to prevent possible medication errors. Similarly, the families said they would like to have access to all kinds of information on the care of their children, and would welcome a reliable web site where they could find answers and report errors.
Developing future strategies to prevent pediatric medication errors requires the input of pediatricians and parents or caregivers. The results of this study could therefore help pediatricians, clinical directors, pharmacists and health policy makers to ensure comprehensive patient care. The survey responses could also be used to develop preventive measures in the pediatric primary care or community pharmacy setting, or to develop error notification systems for parents and caregivers. This study takes the forefront of the new strategies implemented by national health systems in different countries, where caregivers describe their information needs in order to provide tools for better management of home care, particularly in relation to medication. Providing strategies to prevent medication errors and learning from mistakes made at home appear to be new challenges to address [
23].
The main limitations of this study include the use of an ad-hoc survey to collect the opinion of study participants without information on the validity and reliability of the questionnaire, and the potential bias resulting from nonprobability sampling. Indeed, most of our respondents lived in the Valencian Community, and our results therefore cannot be generalized to the whole population. Because most of the questions in the family survey were open, some participants misinterpreted questions or were unable to answer them. This may be due to false beliefs regarding possible medication errors. Finally, to ensure data anonymity, respondents were not asked to provide personal data, meaning the same person could complete the survey more than once. To prevent this, however, we checked respondents’ IP addresses.
Conclusion
Most pediatricians and families believe that following medical treatment is not among the main difficulties faced by parents in caring for their children. To resolve doubts related to their children’s health, most parents say that they consult a healthcare professional, while most pediatricians think that parents consult the internet. Pediatricians and families alike believe that parents’ and caregivers’ lack of knowledge is a main cause of pediatric medication errors. This study has been able to describe the differences between the perceptions of families and paediatricians regarding the different problem situations that can be found in the home. Having this classification of problem situations from both points of view and the importance of medication errors and the sources of information that should be consulted in case the information is needed are fundamental elements when building a reporting system. The reporting of the error or problematic situation can contribute to generating recommendations so that families learn to better manage this type of situation, always bearing in mind that in case of doubt, the healthcare professional is the point of reference, as this study has also found.
