Abstract

Objectives: Main goal in this study was to design and introduce a standard checklist that medical interns to be able to apply it to assess the medication safety status in clinical settings and learn the facts related to this issue simultaneously.

Methods: We performed the following steps to conduct the study: (1) using brainstorming and fishbone method for collecting problems in six domains including: demographic and risk factors, prescribing, transcribing, usage, storage and management; (2) collecting the medication standards and indicators; (3) designing a problem oriented checklist, including 85 questions; (4) verifying the validity and reliability of designed checklist by Delphi method and conducting a pilot study. The Cronbach's alpha co efficient were good (more than0.7); (5) to perform of pretest; (6) teaching and introducing of 10 valid evidences to answer the checklist questions in three day workshop to 41 medical interns; (7) after the workshop, students applied the mentioned checklist for assessment of drug safety status on 151 hospitalized patients with the aim of learning during assessment; (8) monitoring of patient’s medication safety status by the interns and self -learning simultaneously; and finally (9) we used Student self-assessment of medication safety education goals, before and after self-training with our checklists.

Results: A standard checklist with dual functions (self-learning during assessment) was developed. Difference between pre-test and post test scores was statistical significant (P ≤ 0.001) and 92% of participants were satisfied with this type of training.

Conclusions: We recommend our designed checklist to all clinical educators who are engaged in medication safety domain.

1. Background

1.1. Why Medication Safety?

Every year, nearly 98,000 people die in US hospitals from preventable medical errors, and these mistakes cost $30 billion and increased health expenditures (1). As well as, in the United States, every year, approximately 70,000 hospitalized children, experience at least one adverse event, which 60% of them may be preventable (2). Researchers have estimated that, between 9250 to 23,750 deaths related to adverse drug events (ADEs) have been prevented only in the year 2000 (3). Irrational administration and use of the drugs, increase the side effects of drugs, drug interactions, the development of antibiotic-resistant organisms (4) and increased mortality rates. Therefore, “patient safety”, specially “medication safety” is a very important topic which should be taught at the different clinical medical sciences in universities. Schools of medical sciences (medical, dental, nursing, etc.) are addressing patient safety subject through their curriculum modification. As well as, the Accreditation Council for Pharmacy Education (ACPE) strongly encourages adding the patient safety issue into the pharmacy curricula. The WHO has also recently developed a helpful patient safety curriculum for medical sciences students. In Iran, it has also been incorporated in various courses in undergraduate curriculums (2, 5, 6). The Patient safety course, are included as an elective course in medical student’s curriculum in Iran (5). But, most students do not choose it, because the attitude of medical students about health related issues more focus on remedial problems (curative issues), so, there is no much tendency to engage to community health issues by them. Therefore, due to the importance of the subject, the designed tool is not only applicable for monitoring and supervision, but also it can be used for self-directed landing in most clinical settings. It also helps to integrate basic sciences into clinical one.

Self-directed learning (SDL) is a learner centered approach (7) which it’s special features are as follows: a learning method based on learner needs; formulating learning goals by the learner; identifying human and material sources by the learner him/her- self; evaluating learning outcomes by him/her (8). It is necessary to mention that, currently, there are no any clinical pharmacologists in clinical departments of Azad university hospitals, so the use of SDL method might be a good way to train medical students. So far, a checklist has been used as an evaluation tool and it is less used as an educational tool. A checklist can have multiple applications. For example, it can be applying as a guide to doing a job (e.g. in aviation) (7), to perform a procedure (e.g. WHO surgical checklist) (8), to evaluate professional tasks, to qualification and promoting of processes like patient safety checklist (checklist is a common tool for preventing human errors) (9, 10), it is a tool for learning outcomes assessment, it use as an instrument for self- care and self – regulation (11), it is a tool for a comprehensive look of activities, standardization of activities, and it is a tool for decreasing critical task omissions (8), it is as a guide to transparent division of the tasks, to increase accountability, as well as, to increase the cognitive load (12) and also, it may apply to transfer of knowledge and experiences.

2. Objectives

The main goal in this study was to design and introduce a standard checklist that medical interns to be able to apply it to assess the medication safety status in clinical settings and learn the facts related to this issue simultaneously

3. Methods

The research steps were as follow: Provide a list of possible problems by Ishikawa diagram for collecting problems in six domains including: demographic facilitators and risk factors, prescribing, transcribing, usage, storage and management. (Ishikawa diagram or fishbone technique is a method for listing problems with brain storming and rout cause analysis of problems) (13). Then collecting of drug safety standards, with emphasis on WHO indicators.

Designing a dual function checklist (for assessment of medication safety and self-directed learning simultaneously) including 85 questions. The main format of the questionnaire was a “checklist” (an objective closed questionnaire) with dual educational and supervisory functions which designed as a tool for monitoring of drug events in hospitals and learn the facts simultaneously. The questions of checklist were classified in six categories including: demographic information of the patients, risk factors and facilitators (32 items), prescribing related questions (18 items), transcribing related questions (status of medical orders implementation by nurses) (3 items), rational medication use (RMU) (9 items), drugs reserving and storing indicators (17 items) and drug management indices (6 items) (14, 15).

Verifying the validity and reliability of designed checklist by Delphi method and conducting a pilot study. To confirm the content and face validity of the questionnaire, we inquired the opinions of 15 different experts included: seven clinical specialists, three social & preventive medicine specialists, three pharmacists, one Ph.D. of social determinants of health (SDH) and one nursing MSc (as patient safety executive director in hospital). As well as, to confirm of reliability of the checklist, the questioner was piloted by 41 medical interns who first had a three days designed theoretical and workout training course, then, after the necessary coordination and division of labor, they referred to the different clinical wards of the hospitals and completed the questionnaire for 151 hospitalized patients. Cronbach's alpha and Guttman split half and Spearman-Brown methods were used to measure reliability. The Cronbach's alpha coefficients for main studied domain (medication administration, usage, storage and management) were good (0.788, 0.712, 0.714 and 0.742, respectively). Split- half reliability coefficients for total scale was r = 606. Next step is to perform of pretest.

Teaching and introducing of 10 valid evidences to answer the checklist questions in three-day workshop to 41 medical interns (Table 1)

Monitoring of patient’s medication safety status by the interns and self -learning simultaneously; and finally, we used, student self-assessment of medication safety education goals, before and after self-training with our checklists

Medical interns were chosen as the learners because they have relatively good information about the drugs and they are allowed to enter various medical units and they have access to patient’s profiles and nursing kardexes. As well as, they are able to communicate with managers, doctors, nurses, technicians and patients.

4. Results

We have developed a checklist with dual function of "evaluation" and "training" of medication safety in clinical wards. Details of the questionnaire are discussed below. This checklist has been used for more than one year with the approval of the department as a component of social medical education in community & preventive medicine department of Islamic Azad University, Tehran, Iran. This questionnaire of drug safety in the hospital consists of five separate parts, that each of which can be used separately. Assessors can be physicians, nurses responsible for patient safety plans in the hospital (with the purpose of evaluation) or the medical interns and pharmacotherapy residents (with the purpose of evaluation and self-education) as well as researchers. Part 1, demographic information and factors affecting patient safety issues (refer to the patient’s file); Part 2, evaluation of prescribing errors (refer to the patient’s file); Part 3, evaluation of transcribing errors (refer to nursing Kardexes and nursing reports); Part 4, questions related to medication preserving and storage (16) (refer to shelf or drug and treatment room); Part 5, questions related to medication management in the hospital. The change in attitude, knowledge and experiences of students was evaluated with a rating scale on 41 participants (medical interns) which the results were shown in Table 2.

5. Discussion

Prescribing, transcribing, applying, reserve & storing and managing the drugs are important activities that medical students must be familiar with them. In this study, we have developed a standard checklist for evaluation of medication safety and we have introduced it as a tool for monitoring the medication safety and learning different situations simultaneously.

Using a checklist makes us aware of the problems that are out of our sight. A completely transparent and standard checklist can play an important role in documenting of experiences. Checklists are commonly suggested tools to reduce errors (12); and also a checklist may be given to students to use it to accomplish and complete the steps of a procedure (16).

Ellen Kok et al., with using a Chest Radiograph checklist have shown that, a checklist can help medical students to detect more abnormalities on the chest radiographs (11). As well as, Sibbald et al., in another study have shown that, the checklists reduce diagnostic errors (12).

The attitude of medical students about health related issues more focus on remedial problems (curative issues), so there is no much tendency to engage to community health issues by them. Therefore, at the beginning of the course, some students did not agree with the fact that attention to patient safety concept is a part of their professional tasks, while this issue (medication safety) has been considered in their new curriculum.

Despite the initial opposition, most students gradually became aware to importance of the subject, so that, the final evaluation of the short educational course showed that 94.9% of students were satisfied with this type of training. As well as, in our study, 84.6% of the participants were agreed with changing their attitudes toward education about the necessity to pay attention to the patient safety and medication error issues. Almaramhy et al., have shown that, only 60.7% of medical students were agree with the importance of the patient safety subject (17). This is while in our study, 92.3% of students accepted the issue of patient safety as a professional duty in their mind.

The changes in relation to 6 out of 8 questions in the pretest and posttest scores, as well as, the total score were statistical significantly different. Two topics that had no statistical significant changes were drug abbreviations and list of emergency trolley drugs that we should work on them more.

The medication error checklist was validated by experts and the reliability of the checklist in a pilot study was approved (Cronbach's alpha coefficient were above 0.7) (18).

In calculating reliability of “medication administration error” questionnaire in Taheri et al. study in 2013, Cronbach's alpha was equal to 0.712 for different types of non-injection medication errors and 0.841 for different types of injection medication errors (19).

As well as, in Vizeshfar et al. research in 2015, pharmacological errors questionnaire was used and the validity of each part was specified with content validity and reliability method was affirmed by Cronbach’s alpha coefficient (alpha = 80) (20).

5.1. Study Limitations

Although the questionnaire seems a bit long and time consuming, but in certain circumstances, the questionnaire can be divided into four complete distinct parts including: prescribing, transcribing and usage, storage and managing the drugs.

5.2. Conclusion

The results of student self-assessment, demonstrate the usefulness of our checklists in student self-training of medication safety. Therefore, we recommend using this dual function checklist (self- directed learning via evaluation of medication safety status) to all clinical educators who are engaged in this domain (clinicians), especially when there are no clinical pharmacologists in clinical settings.

5.3. Achievements

Design a dual functions checklist; attracting students to a critical professional task; assist in the implementation of patient safety monitoring programs in the hospital.
