Prospective pilot intervention study to prevent medication errors in drugs administered to children by mouth or gastric tube: a programme for nurses, physicians and parents

Medication Errors in Pediatrics: Proposals to Improve the Quality and Safety of Care Through Clinical Risk Management

Medication errors represent one of the most common causes of adverse events in pediatrics and are widely reported in the literature. Despite the awareness that children are at increased risk for medication errors, little is known about the real incidence of the phenomenon. Most studies have focused on prescription, although medication errors also include transcription, dispensing, dosage, administration, and certification errors. Known risk factors for therapeutic errors include parenteral infusions, oral fluid administration, and tablet splitting, as well as the off-label use of drugs with dosages taken from adult literature. Emergency Departments and Intensive Care Units constitute the care areas mainly affected by the phenomenon in the hospital setting. The present paper aims to identify the risk profiles in pediatric therapy to outline adequate preventive strategies. Precisely, through the analysis of the available evidence, solutions such as standardization of recommended doses for children, electronic prescribing, targeted training of healthcare professionals, and implementation of reporting systems will be indicated for the prevention of medication errors.

Drug-handling problems and expectations of the ideal pediatric drug-reported by children and their parents

Experienced drug-handling problems and inadequately considered expectations for drug therapy have an unfavorable influence on therapy. We performed a questionnaire survey in (i) parents of 0-5-year-old children and (ii) 6-17-year olds and their parents. We assessed (A) experienced drug-handling problems and (B) expectations for drug therapy. (i) Forty-six parents and (ii) 103 children and their parents participated in the study. Experienced drug-handling problems were described by (i) 100% of parents and (ii) 62% of children and 70% of parents. Problems concerned with the preparation of the drug, dosing, compliance with the time interval, and acceptance. (i) Sixty-five percent of parents preferred a peroral route of drug administration, while (ii) 74% of children and 86% of parents did so. Preferred characteristics of peroral drug formulations, e.g., liquid versus solid drug formulations or flavor, were highly heterogeneous. Preferences of 6-17-year-old children and their parents matched in 43 to 66%.   Conclusion: Most children and their parents had already experienced drug-handling problems. Preferences concerning the ideal pediatric drug were highly heterogeneous and in about half of cases, preferences of children and their parents differed. Thus, the children should be approached directly. If information is solely gained from parents, the children's needs might remain unmet. What is Known: • Pediatric drug administration is complex and therefore error-prone. • Experiences and expectations of children and their parents should be considered. What is New: •Most pediatric patients and their parents have already experienced drug-handling problems. • Expectations concerning the ideal pediatric drug are highly heterogeneous. Parents are often insufficiently aware of those expectations in their children.

Counseling patients on correct drug handling in German community pharmacies: experiences and opinions of pharmaceutical staff

Background For a safe drug therapy, outpatients have to self-administer their medications correctly. However, these procedures are known as error-prone. In community pharmacies, the pharmaceutical staff has to recognize patients' counseling needs and to use adequate strategies to prevent possible handling errors. Objective Assessing the experiences and opinions of pharmaceutical staff on counseling patients on practical drug handling. Setting Community pharmacies in a German city and surrounding area. Method Descriptively evaluating a self-administered questionnaire to be completed by members of the pharmaceutical staff involved in patient counseling. Main outcome measures Estimated counseling needs of patients, current counseling strategies and limitations of counseling. Results 520 staff members of 119 pharmacies (59.8%, 199 invited) participated. The majority prioritized counseling on dosage over counseling on practical drug handling. Participants saw a particular need when medication was dispensed for the first time compared to repeated use (all medication types, each p < 0.001). The need and counseling strategy depended on the dosage form with a special focus on practical demonstration in bronchopulmonary (83.9%) and oral liquid formulations (54.3%). As one main limitation, they cited the refusal of patients to accept information on drug handling (34.4%). Conclusion Participants considered drug handling an important counseling topic. However, reduced awareness for handling errors made at repeated use and at administration of certain dosage forms may affect the safety and success of medication therapy. Additionally, patients' resistance to information may limit the intent on counseling. Still, it is important to verify patients' abilities to handle their medication as intended.

Effects of sharing information on drug administration errors in pediatric wards: a pre-post intervention study

BACKGROUND AND PURPOSE

Drug administration errors are more likely to reach the patient than other medication errors. The main aim of this study was to determine whether the sharing of information on drug administration errors among health care providers would reduce such problems.

PATIENTS AND METHODS

This study involved direct, undisguised observations of drug administrations in two pediatric wards of a major teaching hospital in Kuala Lumpur, Malaysia. This study consisted of two phases: Phase 1 (pre-intervention) and Phase 2 (post-intervention). Data were collected by two observers over a 40-day period in both Phase 1 and Phase 2 of the study. Both observers were pharmacy graduates: Observer 1 just completed her undergraduate pharmacy degree, whereas Observer 2 was doing her one-year internship as a provisionally registered pharmacist in the hospital under study. A drug administration error was defined as a discrepancy between the drug regimen received by the patient and that intended by the prescriber and also drug administration procedures that did not follow standard hospital policies and procedures. Results from Phase 1 of the study were analyzed, presented and discussed with the ward staff before commencement of data collection in Phase 2.

RESULTS

A total of 1,284 and 1,401 doses of drugs were administered in Phase 1 and Phase 2, respectively. The rate of drug administration errors reduced significantly from Phase 1 to Phase 2 (44.3% versus 28.6%, respectively; P<0.001). Logistic regression analysis showed that the adjusted odds of drug administration errors in Phase 1 of the study were almost three times that in Phase 2 (P<0.001). The most common types of errors were incorrect administration technique and incorrect drug preparation. Nasogastric and intravenous routes of drug administration contributed significantly to the rate of drug administration errors.

CONCLUSION

This study showed that sharing of the types of errors that had occurred was significantly associated with a reduction in drug administration errors.

Knowledge of staff members of residential care facilities for individuals with intellectual disability on medication administration via enteral feeding tube

BACKGROUND

Guidelines for the safe administration of drugs through enteral feeding tube (EFT) are an important tool to minimise the risk of errors. This study aimed to investigate knowledge of these guidelines among staff of residential care facilities (RCF) for people with ID.

METHOD

Knowledge was assessed using a 13-item self-administered questionnaire. Questions reflected key aspects of guidelines on medication administration via EFT. All staff members that administer medication through EFT in Belgian RCFs were invited to participate (n = 553).

RESULTS

Nine out of 10 RCFs participated, and 356 questionnaires were collected. Almost all participants were women (96%), and most (82%) had a non-nursing educational background. Mean self-perceived knowledge of medication administration via EFT was 6.7 (on a 0-10 scale). On average, 5.7 (SD 1.9) out of 13 questions were answered correctly. A nursing degree and previous education on medication administration via EFT were associated with significantly higher scores. Guideline recommendations regarding rinsing of used medicine cups (90% correct answers) and preparation of hard gelatin capsules (89%) were known best. Those regarding the use of protective equipment when crushing toxic substances (4% correct answers), crushing of sustained release and enteric-coated dosage forms (6%), elevation of the patient's backrest (14%) and flushing of the EFT (15%) were known the least.

CONCLUSION

This study identified a substantial lack of knowledge of guidelines for drug administration through EFT among staff of RCFs for people with ID. Our findings call for tailored educational programmes in order to increase knowledge on this subject.

Systematic literature review of hospital medication administration errors in children

Objective

Medication administration is the last step in the medication process. It can act as a safety net to prevent unintended harm to patients if detected. However, medication administration errors (MAEs) during this process have been documented and thought to be preventable. In pediatric medicine, doses are usually administered based on the child’s weight or body surface area. This in turn increases the risk of drug miscalculations and therefore MAEs. The aim of this review is to report MAEs occurring in pediatric inpatients.

Methods

Twelve bibliographic databases were searched for studies published between January 2000 and February 2015 using “medication administration errors”, “hospital”, and “children” related terminologies. Handsearching of relevant publications was also carried out. A second reviewer screened articles for eligibility and quality in accordance with the inclusion/exclusion criteria.

Key findings

A total of 44 studies were systematically reviewed. MAEs were generally defined as a deviation of dose given from that prescribed; this included omitted doses and administration at the wrong time. Hospital MAEs in children accounted for a mean of 50% of all reported medication error reports (n=12,588). It was also identified in a mean of 29% of doses observed (n=8,894). The most prevalent type of MAEs related to preparation, infusion rate, dose, and time. This review has identified five types of interventions to reduce hospital MAEs in children: barcode medicine administration, electronic prescribing, education, use of smart pumps, and standard concentration.

Conclusion

This review has identified a wide variation in the prevalence of hospital MAEs in children. This is attributed to the definition and method used to investigate MAEs. The review also illustrated the complexity and multifaceted nature of MAEs. Therefore, there is a need to develop a set of safety measures to tackle these errors in pediatric practice.

Managing of oral medicines in paediatric oncology: can a handbook and a pharmaceutical counselling intervention for patients and their parents prevent knowledge deficits? A pilot study

Objectives

To assess knowledge deficits of patients/parents and prevention strategies.

Methods

After receiving ethics approval, we performed a controlled, quasi-randomised, prospective intervention study. We enrolled patients/parents involved in managing oral medicines in three groups: control (routine care only), handbook intervention and pharmaceutical counselling intervention group. At baseline and after the interventions, we assessed patients'/parents' knowledge deficits (incorrect or missing answers) by questionnaire.

Results

We enrolled 64 patients/parents. At baseline, knowledge deficits among the groups were similar: 17% in controls, 22% in the handbook group and 24% in the pharmaceutical counselling group. After the intervention, knowledge deficits decreased to 13% in the handbook group and to 8% in the pharmaceutical counselling group (NS; p=0.003 compared with controls, respectively). For controls, knowledge deficits remained almost unchanged (19%). Results for the pharmaceutical counselling group showed a strong correlation between baseline knowledge deficits and the extent of the deficit decrease after the intervention (τ=-0.74; p<0.001), whereas no significant correlation was found in the control or handbook group.

Conclusions

In paediatric oncology, patients'/parents' knowledge of managing oral medicines was improved. Pharmaceutical counselling substantially reduced high knowledge deficits but no significant improvement was seen with the handbook approach. Pharmaceutical counselling should be offered to patients/parents with high knowledge deficits to reduce errors in managing medicines and increase safety.

Development and evaluation of an algorithm to facilitate drug prescription for inpatients with feeding tubes

PURPOSE

We aimed to develop and evaluate an algorithm to facilitate drug switching between primary and tertiary care for patients with feeding tubes.

METHODS

An expert consortium developed an algorithm and applied it manually to 267 preadmission drugs of 46 patients admitted to a surgical ward of a tertiary care university hospital between June 12 and December 2, 2013, and requiring a feeding tube during their inpatient stay.

RESULTS

The new algorithm considered the following principles: Drugs should be ideally listed on the hospital drug formulary (HDF). Additionally, drugs should include the same ingredient instead of a therapeutic equivalent. Preferred dosage forms were appropriate liquids, followed by solid drugs with liquid administration form, and solid drugs that could be crushed and/or suspended. Of all evaluated drugs, 83.5% could be switched to suitable drugs listed on the HDF and another 6.0% to drugs available on the German drug market. Additionally, for 4.1% of the drugs, the integration of individual switching rules allowed the switch from enteric-coated to immediate-release drugs. Consequently, 6.4% of the drugs could not be automatically switched and required case-to-case decision by a clinical professional (e.g., from sustained-release to immediate-release).

CONCLUSIONS

The predefined principles were successfully integrated in the new algorithm. Thus, the algorithm switched more than 90% of the evaluated preadmission drugs to suitable drugs for inpatients with feeding tubes. This finding suggests that the algorithm can readily be transferred to an electronic format and integrated into a clinical decision support system.

How to improve prescription of inhaled salbutamol by providing standardised feedback on administration: a controlled intervention pilot study with follow-up

Background

The effectiveness of inhaled salbutamol in routine care depends particularly on prescribed dosage and applied inhalation technique. To achieve maximum effectiveness and to prevent drug-related problems, prescription and administration need to work in concert.

Methods

We performed a controlled intervention pilot study with 4 consecutive groups in a general paediatric unit and assessed problems in salbutamol prescribing and administration. Control group [i]: Routine care without additional support. First intervention group [ii]: We carried out a teaching session for nurses aimed at preventing problems in inhalation technique. Independently from this, a pharmacist counselled physicians on problems in salbutamol prescribing. Second intervention group [iii]: Additionally to the first intervention, physicians received standardised feedback on the inhalation technique. Follow-up group [iv]: Subsequently, without any delay after the second intervention group had been completed, sustainability of the measures was assessed. We performed the chi-square test to calculate the level of significance with p ≤ 0.05 to indicate a statistically significant difference for the primary outcome. As we performed multiple testing, an adjusted p ≤ 0.01 according to Bonferroni correction was considered as significant.

Results

We included a total of 225 patients. By counselling the physicians, we reduced the number of patients with problems from 55% to 43% (control [i] vs. first intervention [ii], n.s.). With additional feedback to physicians, this number was further reduced to 25% ([i] vs. [iii], p < 0.001). In the follow-up [iv], the number rose again to 48% (p < 0.01 compared to feedback group).

Conclusions

Teaching nurses, counselling physicians, and providing feedback on the quality of inhalation technique effectively reduced problems in salbutamol treatment. However, for success to be sustained, continuous support needs to be provided.

Impact of an electronic clinical decision support system on workflow in antenatal care: the QUALMAT eCDSS in rural health care facilities in Ghana and Tanzania

BACKGROUND

The implementation of new technology can interrupt established workflows in health care settings. The Quality of Maternal Care (QUALMAT) project has introduced an electronic clinical decision support system (eCDSS) for antenatal care (ANC) and delivery in rural primary health care facilities in Africa.

OBJECTIVE

This study was carried out to investigate the influence of the QUALMAT eCDSS on the workflow of health care workers in rural primary health care facilities in Ghana and Tanzania.

DESIGN

A direct observation, time-and-motion study on ANC processes was conducted using a structured data sheet with predefined major task categories. The duration and sequence of tasks performed during ANC visits were observed, and changes after the implementation of the eCDSS were analyzed.

RESULTS

In 24 QUALMAT study sites, 214 observations of ANC visits (144 in Ghana, 70 in Tanzania) were carried out at baseline and 148 observations (104 in Ghana, 44 in Tanzania) after the software was implemented in 12 of those sites. The median time spent combined for all centers in both countries to provide ANC at baseline was 6.5 min [interquartile range (IQR) =4.0-10.6]. Although the time spent on ANC increased in Tanzania and Ghana after the eCDSS implementation as compared to baseline, overall there was no significant increase in time used for ANC activities (0.51 min, p=0.06 in Ghana; and 0.54 min, p=0.26 in Tanzania) as compared to the control sites without the eCDSS. The percentage of medical history taking in women who had subsequent examinations increased after eCDSS implementation from 58.2% (39/67) to 95.3% (61/64) p<0.001 in Ghana but not in Tanzania [from 65.4% (17/26) to 71.4% (15/21) p=0.70].

CONCLUSIONS

The QUALMAT eCDSS does not increase the time needed for ANC but partly streamlined workflow at sites in Ghana, showing the potential of such a system to influence quality of care positively.

Development of a standardized knowledge base to generate individualized medication plans automatically with drug administration recommendations

AIMS

We aimed to develop a generic knowledge base with drug administration recommendations which allows the generation of a dynamic and comprehensive medication plan and to evaluate its comprehensibility and potential benefit in a qualitative pilot study with patients and physicians.

METHODS

Based on a literature search and previously published medication plans, a prototype was developed and iteratively refined through qualitative evaluation (interviews with patients and focus group discussions with physicians). To develop the recommendations for safe administration of specific drugs we screened the summary of product characteristics (SmPC) of different exemplary brands, allocated the generated advice to groups with brands potentially requiring the same advice, and reviewed these allocations regarding applicability and appropriateness of the recommendations.

RESULTS

For the recommendations, 411 SmPCs of 140 different active ingredients including all available galenic formulations, routes of administrations except infusions, and administration devices were screened. Finally, 515 distinct administration recommendations were included in the database. In 926 different generic groups, 29,879 allocations of brands to general advice, food advice, indications, step-by-step instructions, or combinations thereof were made. Thereby, 27,216 of the preselected allocations (91.1%) were confirmed as appropriate. In total, one third of the German drug market was labelled with information.

CONCLUSIONS

Generic grouping of brands according to their active ingredient and other drug characteristics and allocation of standardized administration recommendations is feasible for a large drug market and can be integrated in a medication plan.

Safeguarding the process of drug administration with an emphasis on electronic support tools

AIMS

The aim of this work is to understand the process of drug administration and identify points in the workflow that resulted in interventions by clinical information systems in order to improve patient safety.

METHODS

To identify a generic way to structure the drug administration process we performed peer-group discussions and supplemented these discussions with a literature search for studies reporting errors in drug administration and strategies for their prevention.

RESULTS

We concluded that the drug administration process might consist of up to 11 sub-steps, which can be grouped into the four sub-processes of preparation, personalization, application and follow-up. Errors in drug handling and administration are diverse and frequent and in many cases not caused by the patient him/herself, but by family members or nurses. Accordingly, different prevention strategies have been set in place with relatively few approaches involving e-health technology.

CONCLUSIONS

A generic structuring of the administration process and particular error-prone sub-steps may facilitate the allocation of prevention strategies and help to identify research gaps.

Reducing the risk of harm from medication errors in children

MEDICATION ERRORS AFFECT THE PEDIATRIC AGE GROUP IN ALL SETTINGS

outpatient, inpatient, emergency department, and at home. Children may be at special risk due to size and physiologic variability, limited communication ability, and treatment by nonpediatric health care providers. Those with chronic illnesses and on multiple medications may be at higher risk of experiencing adverse drug events. Some strategies that have been employed to reduce harm from pediatric medication errors include e-prescribing and computerized provider order entry with decision support, medication reconciliation, barcode systems, clinical pharmacists in medical settings, medical staff training, package changes to reduce look-alike/sound-alike confusion, standardization of labeling and measurement devices for home administration, and quality improvement interventions to promote nonpunitive reporting of medication errors coupled with changes in systems and cultures. Future research is needed to measure the effectiveness of these preventive strategies.

Comparison of a basic and an advanced pharmacotherapy-related clinical decision support system in a hospital care setting in the Netherlands

OBJECTIVE To compare the clinical relevance of medication alerts in a basic and in an advanced clinical decision support system (CDSS).

DESIGN

A prospective observational study.

MATERIALS AND METHODS

We collected 4023 medication orders in a hospital for independent evaluation in two pharmacotherapy-related decision support systems. Only the more advanced system considered patient characteristics and laboratory test results in its algorithms. Two pharmacists assessed the clinical relevance of the medication alerts produced. The alert was considered relevant if the pharmacist would undertake action (eg, contact the physician or the nurse). The primary analysis concerned the positive predictive value (PPV) for clinically relevant medication alerts in both systems.

RESULTS

The PPV was significantly higher in the advanced system (5.8% vs 17.0%; p<0.05). Significant differences were found in the alert categories: drug-(drug) interaction (9.9% vs 14.8%; p<0.05), drug-age interaction (2.9% vs 73.3%; p<0.05), and dosing guidance (5.6% vs 16.9%; p<0.05). Including laboratory values and other patient characteristics resulted in a significantly higher PPV for the advanced CDSS compared to the basic medication alerts (12.2% vs 23.3%; p<0.05).

CONCLUSION

The advanced CDSS produced a higher proportion of clinically relevant medication alerts, but the number of irrelevant alerts remained high. To improve the PPV of the advanced CDSS, the algorithms should be optimized by identifying additional risk modifiers and more data should be made electronically available to improve the performance of the algorithms. Our study illustrates and corroborates the need for cyclic testing of technical improvements in information technology in circumstances representative of daily clinical practice.

Drug utilization patterns and reported health status in ethnic German migrants (Aussiedler) in Germany: a cross-sectional study

Background

Inadequate utilization of healthcare services by migrant populations is an important public health concern. Inadequate drug consumption and poor compliance to the therapeutic regimen are common manifestations of low health-care seeking behavior present in migrants even in the countries with well-established healthcare systems. There are few studies on the use of medicines among the different groups of migrants in Germany. The objective of this study is to investigate drug consumption patterns of ethnic German migrants (Aussiedler) and their current health status.

Methods

A cross-sectional study nested into a cohort of 18,621 individuals aged 20-70 years who migrated to Germany from the former Soviet Union between 1990 and 2005 was conducted. Data on consumption of drugs, drug handling, major health risk factors, and one-year disease prevalence were obtained for 114 individuals through a self-administered questionnaire and phone interviews. Results were compared to the data on the German population derived from the Disease Analyzer database and Robert Koch Institute (RKI) annual reports. Direct age standardization, test of differences, Chi-square test, and descriptive statistics were applied as appropriate. For drug classification the Anatomical Therapeutic Chemical (ATC) system was used.

Results

Of the respondents, 97% reported to have at least one disease within a 12-month period. The one-year prevalence of asthma (6.9%), hypertension (26.7%), chronic bronchitis (8.6%), and diabetes (4.9%) in migrants was similar to the general German population. 51% regularly took either over-the-counter (OTC) medication or prescription medicines. Six ATC groups were analyzed. The highest drug consumption was reported for the ATC cardiovascular (22%), nervous (9%), and muskulo-skeletal system (8%). 30% used OTC medicines obtained in the country of origin. Difficulties with drug handling were rare. Alcohol consumption did not differ from the German population (p = 0.19 males and 0.27 females), however smoking prevalence was lower (p < 0.01) in both sexes.

Conclusion

Ethnic German migrants seem to differ only slightly from Germans in health status, drug utilization, and disease risk factors, and if so, not in an extreme way. Country of origin remains a source of medicines for a substantial part of migrants. The study is limited by a small sample size and low response rate.
