Assessment of the knowledge and attitudes of intern doctors to medication prescribing errors in a Nigeria tertiary hospital

Dose adjustment of rheumatology and allergy/immunology medications in chronic kidney disease: awareness and knowledge among internal medicine housestaff

Background

Patients with chronic kidney disease (CKD) are at increased risk for adverse drug events due to medication dosing errors. We studied the awareness and knowledge among internal medicine housestaff (IMHS) of proper dose adjustment of commonly used rheumatology and allergy/immunology medications for patients with CKD.

Methods

We surveyed 353 IMHS to evaluate their awareness of the need for medication dose adjustments for patients with CKD and knowledge for medication adjustment by level of glomerular filtration rate for common rheumatology and allergy/immunology medications.

Results

There was lack of awareness and knowledge for both rheumatology and allergy/immunology medications. Incorrect awareness and knowledge were as follows: allopurinol, 21.2%, 73.4%; colchicine, 19.0%, 75.9%; diphenhydramine, 34.0%, 34.0%; loratadine, 82.2%, 93.2%; and montelukast, 34.0%, 34.0%, respectively. Exploratory logistic regression analyses showed that PGY1 residents had higher odds for lack of awareness for allopurinol (odds ratio [OR] 24.57, 95% CI [confidence interval] 4.69, 99.13, P < 0.001), colchicine (OR 3.98, 95% CI 1.50, 10.51, P < 0.01), diphenhydramine (OR 2.24, 95% CI 1.10, 4.54, P < 0.04), and montelukast (OR 2.45, 95% CI 1.20, 5.00, P < 0.05) than PGY3 residents. A nephrology rotation in medical school was associated with lower odds for incorrect knowledge for allopurinol (OR 0.46, 95% CI 0.25, 0.87, P < 0.05) and montelukast (OR 0.50, 95% CI 0.27, 0.92, P < 0.05).

Conclusion

Overall, awareness and knowledge were poor among IMHS for dose adjustments of rheumatology and allergy/immunology medications in patients with CKD. Proper education and exposure to nephrology during training may improve quality and safety of care for patients with CKD.

Predictors of antibiotic prescriptions: a knowledge, attitude and practice survey among physicians in tertiary hospitals in Nigeria

BACKGROUND

As part of the Global Action Plan against antimicrobial resistance (AMR), countries are required to generate local evidence to inform context-specific implementation of national action plans against AMR (NAPAR). We aimed to evaluate the knowledge, attitude, and practice (KAP) regarding antibiotic prescriptions (APR) and AMR among physicians in tertiary hospitals in Nigeria, and to determine predictors of KAP of APR and AMR.

METHODS

In this cross-sectional study, we enrolled physicians practicing in tertiary hospitals from all six geopolitical zones of Nigeria. Implementation of an antimicrobial stewardship programmes (ASP) by each selected hospital were assessed using a 12 item ASP checklist. We used a structured self-administered questionnaire to assess the KAP of APR and AMR. Frequency of prescriptions of 18 different antibiotics in the prior 6 months was assessed using a Likert's scale. KAP and prescription (Pr) scores were classified as good (score ≥ 80%) or average/poor (score < 80%). Independent predictors of good knowledge, attitude, and practice (KAPPr) were ascertained using an unconditional logistic regression model.

RESULTS

A total of 1324 physicians out of 1778 (74% response rate) practicing in 12 tertiary hospitals in 11 states across all six geopolitical zones participated in the study. None of the participating hospitals had a formal ASP programme and majority did not implement antimicrobial stewardship strategies. The median KAPPr scores were 71.1%, 77%, 75% and 53.3%, for the knowledge, attitude, practice, and prescription components, respectively. Only 22.3%, 40.3%, 31.6% and 31.7% of study respondents had good KAPPr, respectively. All respondents had prescribed one or more antibiotics in the prior 6 months, mostly Amoxicillin-clavulanate (98%), fluoroquinolones (97%), and ceftriaxone (96.8%). About 68% of respondents had prescribed antibiotics from the World Health Organization reserve group. Prior AMR training, professional rank, department, and hospital of practice were independently associated with good KAPPr.

CONCLUSIONS

Our study suggests gaps in knowledge and attitude of APR and AMR with inappropriate prescriptions of antibiotics among physicians practicing in tertiary hospitals in Nigeria. Nigeria's NAPAR should also target establishment and improvement of ASP in hospitals and address institutional, educational, and professional factors that may influence emergence of AMR in Nigeria.

Tackling Antimicrobial Resistance by promoting Antimicrobial stewardship in Medical and Allied Health Professional Curricula

INTRODUCTION

Antimicrobial resistance poses a serious threat to global health with significantly higher morbidity, mortality, and economic burden. This review aims to discuss the importance of the promotion of antimicrobial stewardship in medical and allied health professional curricula and training/educating tomorrow's doctors in combatting antimicrobial resistance. A narrative literature review was conducted to retrieve relevant information related to antimicrobial resistance and stewardship and their implications on medical and allied health professional education and training from searches of computerized databases, hand searches, and authoritative texts.

AREAS COVERED

Antimicrobial stewardship programs improve rational antibiotic use, reduce antimicrobial resistance, decrease complications of antibiotic use, and improve patient outcomes. Though health professional students recognize the importance and impact of antibiotic prescribing knowledge, many studies have consistently demonstrated low levels of confidence and competencies amongst students, highlighting that health professional schools failed to prepare them to prescribe antibiotics accurately.

EXPERT OPINION

There is an urgent call for the integration of antimicrobial stewardship teaching at the undergraduate level of medical education to train future prescribers on this critical aspect of public health. Proper undergraduate education on rational antibiotics use would enable health professional graduates to enter clinical practice with adequate competencies to become rational prescribers.

Competence and confidence with prescribing in pharmacy and medicine: a scoping review

OBJECTIVES

Prescribing is a growing scope of practice for pharmacists. The objective of this scoping review is to explore themes within the literature related to prescribing competence and confidence in the disciplines of pharmacy and medicine.

METHODS

Online databases MEDLINE, EMBASE and Global Health were used to identify articles from inception to October 2018. Articles describing either the competence or confidence of physician, pharmacist or student prescribing, including inappropriate prescribing and prescribing errors were included.

KEY FINDINGS

After applying the inclusion and exclusion criteria, 33 eligible articles remained. Many studies demonstrate that medical students and junior doctors are not competent in prescribing when they enter practice, and their perceived confidence is often higher than their assessed competence. There were fewer studies about pharmacist competence and confidence with prescribing; however, they described pharmacists that felt competent to prescribe but lacked confidence. Themes from the review included self-awareness, lack of education and educational improvements, prescribing errors and resources, prescribing culture and barriers to prescribing, gender differences and benefits to prescribing.

CONCLUSIONS

There is little consensus from the outcomes of these studies related to prescribing competence or confidence. While some reflect positively on prescribing competence and confidence, others show major deficits in competence and lack of confidence. Further research needs to be done to evaluate pharmacist competence and confidence with respect to prescribing.

Adherence to prescription-writing guidelines for outpatients in Southern Gauteng district hospitals

Background

Medical prescription writing is legally and professionally regulated in order to prevent errors that can result in patients being harmed. This study assesses prescriber adherence to such regulations in primary care settings.

Methods

A cross-sectional study of 412 prescriptions from four district hospital outpatient departments (OPDs) was conducted in March 2015. Primary outcome data were obtained by scoring prescriptions for accuracy across four categories: completion of essential elements, use of generic names of medications, use of recommended abbreviations and decimals and legibility. Secondary outcome data sought associations between accuracy scores and characteristics of the OPDs that might influence prescriber adherence.

Results

Completion of the essential elements, including patient identifiers, prescriber identifiers, treatment regimen and date scored 44%, 77%, 99% and 99% respectively. Legibility, the use of generic names of medications and the use of recommended abbreviations and decimals scored 90%, 39% and 35%, respectively. Only 38% of prescriptions achieved a global accuracy score (GAS) of between 80% and 100%. A significant association was found between lower GAS and the number of prescriptions written per day (p = 0.001) as well as with the number of prescribers working on that day (p = 0.005), suggesting a negative impact on prescribers’ performance because of workload pressures.

Conclusion

Low GAS values indicate poor adherence to prescription-writing regulations. Elements requiring substantial improvement include completion of patient and prescriber identifiers, use of generic medication names and the use of recommended abbreviations and decimals. This study provides baseline data for future initiatives for improvement in prescription-writing quality.

Healthcare professionals' level of medication knowledge in Africa: a systematic review

AIMS

Understanding how much healthcare professionals (HCPs) know about medication can help in devising strategies to improve rational medication use. This study aimed to synthesize information on the level of medication knowledge of HCPs in Africa.

METHOD

We performed a systematic literature study in Embase and PubMed. We included original studies quantifying HCPs' medication knowledge, published between 2012 and 2016. We extracted disease focus, country, number and type of HCPs included and all medication-related knowledge questions and scored the quality of papers. The outcome measure was the percentage of HCPs who correctly answered medication knowledge questions.

RESULTS

We identified 64 studies from 12 African countries, comprising 13 911 HCPs, mostly nurses/midwifes and physicians. We extracted 306 medication-related knowledge questions, and only 52% (SD 28) of HCPs correctly answered them. Knowledge questions were mainly about medication prescribed for communicable diseases (70%), followed by non-communicable diseases (11%), and family planning/gynaecology (10%). Most papers concluded that there was a considerable medication knowledge gap among HCPs.

CONCLUSION

We found a low level of medication knowledge across different disease areas, countries and HCPs. This underlines the continuous need to strengthen the undergraduate and postgraduate education in (clinical) pharmacology and therapeutics in Africa.

The effect of human resource management on performance in hospitals in Sub-Saharan Africa: a systematic literature review

Hospitals in Sub-Saharan Africa (SSA) face major workforce challenges while having to deal with extraordinary high burdens of disease. The effectiveness of human resource management (HRM) is therefore of particular interest for these SSA hospitals. While, in general, the relationship between HRM and hospital performance is extensively investigated, most of the underlying empirical evidence is from western countries and may have limited validity in SSA. Evidence on this relationship for SSA hospitals is scarce and scattered. We present a systematic review of empirical studies investigating the relationship between HRM and performance in SSA hospitals.Following the PRISMA protocol, searching in seven databases (i.e., Embase, MEDLINE, Web of Science, Cochrane, PubMed, CINAHL, Google Scholar) yielded 2252 hits and a total of 111 included studies that represent 19 out of 48 SSA countries.From a HRM perspective, most studies researched HRM bundles that combined practices from motivation-enhancing, skills-enhancing, and empowerment-enhancing domains. Motivation-enhancing practices were most frequently researched, followed by skills-enhancing practices and empowerment-enhancing practices. Few studies focused on single HRM practices (instead of bundles). Training and education were the most researched single practices, followed by task shifting.From a performance perspective, our review reveals that employee outcomes and organizational outcomes are frequently researched, whereas team outcomes and patient outcomes are significantly less researched. Most studies report HRM interventions to have positively impacted performance in one way or another. As researchers have studied a wide variety of (bundled) interventions and outcomes, our analysis does not allow to present a structured set of effective one-to-one relationships between specific HRM interventions and performance measures. Instead, we find that specific outcome improvements can be accomplished by different HRM interventions and conversely that similar HRM interventions are reported to affect different outcome measures.In view of the high burden of disease, our review identified remarkable little evidence on the relationship between HRM and patient outcomes. Moreover, the presented evidence often fails to provide contextual characteristics which are likely to induce variety in the performance effects of HRM interventions. Coordinated research efforts to advance the evidence base are called for.

Interventions to improve antimicrobial prescribing of doctors in training (IMPACT): a realist review

Background

Interventions to improve the antimicrobial prescribing practices of doctors have been implemented widely to curtail the emergence and spread of antimicrobial resistance, but have been met with varying levels of success.

Objectives

This study aimed to generate an in-depth understanding of how antimicrobial prescribing interventions ‘work’ (or do not work) for doctors in training by taking into account the wider context in which prescribing decisions are enacted.

Design

The review followed a realist approach to evidence synthesis, which uses an interpretive, theory-driven analysis of qualitative, quantitative and mixed-methods data from relevant studies.

Setting

Primary and secondary care.

Participants

Not applicable.

Interventions

Studies related to antimicrobial prescribing for doctors in training.

Main outcome measures

Not applicable.

Data sources

EMBASE (via Ovid), MEDLINE (via Ovid), MEDLINE In-Process & Other Non-Indexed Citations (via Ovid), PsycINFO (via Ovid), Web of Science core collection limited to Science Citation Index Expanded (SCIE) and Conference Proceedings Citation Index – Science (CPCI-S) (via Thomson Reuters), Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Database of Systematic Reviews, the Health Technology Assessment (HTA) database (all via The Cochrane Library), Applied Social Sciences Index and Abstracts (ASSIA) (via ProQuest), Google Scholar (Google Inc., Mountain View, CA, USA) and expert recommendations.

Review methods

Clearly bounded searches of electronic databases were supplemented by citation tracking and grey literature. Following quality standards for realist reviews, the retrieved articles were systematically screened and iteratively analysed to develop theoretically driven explanations. A programme theory was produced with input from a stakeholder group consisting of practitioners and patient representatives.

Results

A total of 131 articles were included. The overarching programme theory developed from the analysis of these articles explains how and why doctors in training decide to passively comply with or actively follow (1) seniors’ prescribing habits, (2) the way seniors take into account prescribing aids and seek the views of other health professionals and (3) the way seniors negotiate patient expectations. The programme theory also explains what drives willingness or reluctance to ask questions about antimicrobial prescribing or to challenge the decisions made by seniors. The review outlines how these outcomes result from complex inter-relationships between the contexts of practice doctors in training are embedded in (hierarchical relationships, powerful prescribing norms, unclear roles and responsibilities, implicit expectations about knowledge levels and application in practice) and the mechanisms triggered in these contexts (fear of criticism and individual responsibility, reputation management, position in the clinical team and appearing competent). Drawing on these findings, we set out explicit recommendations for optimal tailoring, design and implementation of antimicrobial prescribing interventions targeted at doctors in training.

Limitations

Most articles included in the review discussed hospital-based, rather than primary, care. In cases when few data were available to fully capture all the nuances between context, mechanisms and outcomes, we have been explicit about the strength of our arguments.

Conclusions

This review contributes to our understanding of how antimicrobial prescribing interventions for doctors in training can be better embedded in the hierarchical and interprofessional dynamics of different health-care settings.

Future work

More work is required to understand how interprofessional support for doctors in training can contribute to appropriate prescribing in the context of hierarchical dynamics.

Prevalence and pattern of prescription errors in a Nigerian kidney hospital

OBJECTIVES

To determine (i) the prevalence and pattern of prescription errors in our Centre and, (ii) appraise pharmacists' intervention and correction of identified prescription errors.

DESIGN

A descriptive, single blinded cross-sectional study.

SETTING

Kidney Care Centre is a public Specialist hospital. The monthly patient load averages 60 General Out-patient cases and 17.4 in-patients.

PARTICIPANTS

A total of 31 medical doctors (comprising of 2 Consultant Nephrologists, 15 Medical Officers, 14 House Officers), 40 nurses and 24 ward assistants participated in the study. One pharmacist runs the daily call schedule. Prescribers were blinded to the study. Prescriptions containing only galenicals were excluded.

INTERVENTIONS

An error detection mechanism was set up to identify and correct prescription errors. Life-threatening prescriptions were discussed with the Quality Assurance Team of the Centre who conveyed such errors to the prescriber without revealing the on-going study.

MAIN OUTCOME MEASURES

Prevalence of prescription errors, pattern of prescription errors, pharmacist's intervention.

RESULTS

A total of 2,660 (75.0%) combined prescription errors were found to have one form of error or the other; illegitimacy 1,388 (52.18%), omission 1,221(45.90%), wrong dose 51(1.92%) and no error of style was detected. Life-threatening errors were low (1.1-2.2%). Errors were found more commonly among junior doctors and non-medical doctors. Only 56 (1.6%) of the errors were detected and corrected during the process of dispensing.

CONCLUSION

Prescription errors related to illegitimacy and omissions were highly prevalent. There is a need to improve on patient-to-healthcare giver ratio. A medication quality assurance unit is needed in our hospitals.

Adverse Drug Events and Medication Errors in African Hospitals: A Systematic Review

Background

Medication errors and adverse drug events are universal problems contributing to patient harm but the magnitude of these problems in Africa remains unclear.

Objective

The objective of this study was to systematically investigate the literature on the extent of medication errors and adverse drug events, and the factors contributing to medication errors in African hospitals.

Methods

We searched PubMed, MEDLINE, EMBASE, Web of Science and Global Health databases from inception to 31 August, 2017 and hand searched the reference lists of included studies. Original research studies of any design published in English that investigated adverse drug events and/or medication errors in any patient population in the hospital setting in Africa were included. Descriptive statistics including median and interquartile range were presented.

Results

Fifty-one studies were included; of these, 33 focused on medication errors, 15 on adverse drug events, and three studies focused on medication errors and adverse drug events. These studies were conducted in nine (of the 54) African countries. In any patient population, the median (interquartile range) percentage of patients reported to have experienced any suspected adverse drug event at hospital admission was 8.4% (4.5–20.1%), while adverse drug events causing admission were reported in 2.8% (0.7–6.4%) of patients but it was reported that a median of 43.5% (20.0–47.0%) of the adverse drug events were deemed preventable. Similarly, the median mortality rate attributed to adverse drug events was reported to be 0.1% (interquartile range 0.0–0.3%). The most commonly reported types of medication errors were prescribing errors, occurring in a median of 57.4% (interquartile range 22.8–72.8%) of all prescriptions and a median of 15.5% (interquartile range 7.5–50.6%) of the prescriptions evaluated had dosing problems. Major contributing factors for medication errors reported in these studies were individual practitioner factors (e.g. fatigue and inadequate knowledge/training) and environmental factors, such as workplace distraction and high workload.

Conclusion

Medication errors in the African healthcare setting are relatively common, and the impact of adverse drug events is substantial but many are preventable. This review supports the design and implementation of preventative strategies targeting the most likely contributing factors.

Social and professional influences on antimicrobial prescribing for doctors-in-training: a realist review

Background

Antimicrobial resistance has led to widespread implementation of interventions for appropriate prescribing. However, such interventions are often adopted without an adequate understanding of the challenges facing doctors-in-training as key prescribers.

Methods

The review followed a realist, theory-driven approach to synthesizing qualitative, quantitative and mixed-methods literature. Consistent with realist review quality standards, articles retrieved from electronic databases were systematically screened and analysed to elicit explanations of antimicrobial prescribing behaviours. These explanations were consolidated into a programme theory drawing on social science and learning theory, and shaped though input from patients and practitioners.

Results

By synthesizing data from 131 articles, the review highlights the complex social and professional dynamics underlying antimicrobial prescribing decisions of doctors-in-training. The analysis shows how doctors-in-training often operate within challenging contexts (hierarchical relationships, powerful prescribing norms, unclear roles and responsibilities, implicit expectations about knowledge levels, uncertainty about application of knowledge in practice) where they prioritize particular responses (fear of criticism and individual responsibility, managing one's reputation and position in the team, appearing competent). These complex dynamics explain how and why doctors-in-training decide to: (i) follow senior clinicians' prescribing habits; (ii) take (or not) into account prescribing aids, advice from other health professionals or patient expectations; and (iii) ask questions or challenge decisions. This increased understanding allows for targeted tailoring, design and implementation of antimicrobial prescribing interventions.

Conclusions

This review contributes to a better understanding of how antimicrobial prescribing interventions for doctors-in-training can be embedded more successfully in the hierarchical and inter-professional dynamics of different healthcare settings.
