A systematic review of medication administration errors with transdermal patches

Topical glyceryl trinitrate (GTN) and eccentric exercises in the treatment of mid-portion achilles tendinopathy (the NEAT trial): a randomised double-blind placebo-controlled trial

OBJECTIVES

To investigate if daily treatment with glyceryl trinitrate (GTN) ointment, over 24 weeks combined with a 12-week eccentric exercise programme is more effective for chronic mid-portion Achilles tendinopathy than placebo ointment and eccentric exercise.

METHODS

This was a single-site randomised double-blind placebo-controlled trial at an acute hospital, Dublin, Ireland. Patients with chronic mid-portion Achilles tendinopathy were randomised to either 24 weeks of daily GTN ointment or placebo ointment. Both groups received an identical 12-week eccentric exercise programme. The primary outcome measure was the Victorian Institute of Sport Assessment-Achilles (VISA-A) questionnaire at 24 weeks, which measures pain, function and activity. Secondary outcomes included pain severity, self-reported physical function, calf muscle function, pressure pain thresholds and ultrasound changes. Statistical analyses were performed according to intention-to-treat principles.

RESULTS

76 patients (30 women; 46 men, mean age±SD, 45.6±8.2 years) were recruited for the trial. Significant improvements in VISA-A scores occurred in both groups at 6-week, 12-week and 24-week follow-up. The increase was not significantly different between groups, adjusted mean between-group difference from baseline to week 6, -1.33 (95% CI -6.96 to 4.31); week 12, -1.25 (95% CI -8.0 to 5.49) and week 24, -3.8 (95% CI -10.6 to 3.0); negative values favour GTN. There was no significant between-group difference in any of the secondary outcome measures at 6, 12 and 24 weeks.

CONCLUSIONS

Adding daily GTN ointment over 24 weeks to a 12-week eccentric exercise programme did not improve pain, function and activity level in patients with chronic mid-portion Achilles tendinopathy when compared with placebo ointment.

Prescription of transdermal patches in Colombia: A real-world evidence study

BACKGROUND

Transdermal drug delivery has contributed positively to medical practice. However, prescriptions that do not meet minimum quality criteria and medication errors are common.

OBJECTIVE

The objective was to determine how transdermal patches are being prescribed to a group of patients in Colombia, the compliance with established requirements of such prescriptions and the comparisons between correct and incorrect prescriptions.

METHODS

This was a cross-sectional study of prescriptions for transdermal patches using data from a population-based drug dispensing database between December 1 and 31, 2019. Medical prescriptions were randomly reviewed, establishing whether the drugs were appropriately prescribed by the manufacturer's indications or national regulations. Descriptive and bivariate analysis was performed.

RESULTS

A total of 415 prescriptions were reviewed; the prescription was provided to 412 patients with a median age of 76.9 years, and 63.3% were women. Rivastigmine was the most prescribed transdermal patch (57.8%). 66.3% of all prescriptions did not meet the minimum appropriate prescribing standards, especially those for rivastigmine (97.1%). The 7.0% of all prescriptions had posology errors, especially prescriptions for buprenorphine (43.8%). Older patients (84.4% vs 52.5%), from the Pacific region (34.4% vs 23.7%), with manual formulations (22.1% vs 0.8%), dementia (49.0% vs 6.8%), and in management with lipid-lowering drugs (41.8% vs 30.5%), presented incorrect transdermal patch formulations more frequently (p < 0.05).

CONCLUSION

The high proportion of inappropriately prescribed transdermal patches should draw the attention of those responsible for health care to improve the training of physicians and create prescription quality verification systems.

The Identification of Quality Risk Factors for Non-biological Complex Drugs and Epilepsy Drugs Using Statistical Analysis of Formulation-Based Recalls in the USA

Pharmaceutical companies use the quality by design (QbD) approach to build high-quality drug products. A thorough understanding of risk factors is required to successfully employ QbD. In order to better understand risk factors that potentially impact drug product quality and inform future QbD approaches, we hypothesized root causes of drug product recalls based on publicly available data and a retroactive analysis of drug products recalled by the United States Food and Drug Administration (USFDA) from 2012 to 2018. We focused on two categories of drug products that pose unique regulatory challenges and an increased risk of shortage that could hinder the adequate supply of quality medicine to the patient. Knowing the significant risk factors from previous drug product recalls can help inform QbD and avoid future recalls. Quality recall reasons were studied individually to find risk factors associated with each recall category. Logistical regression statistical tests were done in R using a significance level of 0.05 to find correlations between a recalled product and its manufacturing information such as excipients and manufacturing steps. The results showed significant positive and negative correlations, such as products containing magnesium stearate are more likely to be recalled for impurities and degradation. This information could be used in the future to inform the design and manufacturing of drug products, ensuring consumers receive high-quality products with a low risk of recall.

Real-world Utilisation of the Rivastigmine Transdermal Patches Accompanying the use of Risk Minimisation Tools in Patients with Dementia

BACKGROUND

Transdermal patches are convenient to use, especially in patients with Alzheimer's disease (AD)-associated dementia. However, various identified risks of errors in ad- ministering the patches cannot be disregarded. Patient Reminder Cards (PRCs, included a Medica- tion record sheet [MRS]) have been recently introduced as a risk minimisation tool to prevent incor- rect patch use (IU).

OBJECTIVES

This study aimed to assess the effectiveness of PRCs to prevent IU and to investigate the dose titration pattern of rivastigmine patches in a real-world setting.

METHODS

This multinational, observational, 11-month study included patients with AD currently using rivastigmine patches (4.6 mg/day, 9.5 mg/day, 13.3 mg/day) accompanied by a caregiver. Study outcomes were IU, including multiple patch use (MPU), incorrect patch placement, other IUs, perceived usefulness of the PRCs, and titration patterns of the patches.

RESULTS

Of the total 614 patients included, most were aged ≥65 years and had mild-to-moderate AD. Before and during the study, 27.7% and 18.0% of patients reported IU, respectively. Most pa- tients used MRS, and 73.5% rated it 'helpful' and reported lower rates of IU than those who report- ed it 'not helpful' (13.9%-16.5% vs. 20.2%). Overall, 141 patients had dose titrations, with 75.8% being up-titrated from 4.6 mg/day to 9.5 mg/day after a mean duration of 58 days. Safety findings were consistent with the established profile for the rivastigmine patch.

CONCLUSION

PRC was effective as a risk minimisation tool in limiting the inappropriate use of ri- vastigmine patches. The majority of patients requiring dose-change were up-titrated to 9.5 mg/day patches.

Impact of Medication Regimen Simplification on Medication Incidents in Residential Aged Care: SIMPLER Randomized Controlled Trial

In the SImplification of Medications Prescribed to Long-tErm care Residents (SIMPLER) cluster-randomized controlled trial, we investigated the impact of a structured medication regimen simplification intervention on medication incidents in residential aged care facilities (RACFs) over a 12-month follow-up. A clinical pharmacist applied the validated 5-step Medication Regimen Simplification Guide for Residential Aged CarE (MRS GRACE) for 96 of the 99 participating residents in the four intervention RACFs. The 143 participating residents in the comparison RACFs received usual care. Over 12 months, medication incident rates were 95 and 66 per 100 resident-years in the intervention and comparison groups, respectively (adjusted incident rate ratio (IRR) 1.13; 95% confidence interval (CI) 0.53-2.38). The 12-month pre/post incident rate almost halved among participants in the intervention group (adjusted IRR 0.56; 95%CI 0.38-0.80). A significant reduction in 12-month pre/post incident rate was also observed in the comparison group (adjusted IRR 0.67, 95%CI 0.50-0.90). Medication incidents over 12 months were often minor in severity. Declines in 12-month pre/post incident rates were observed in both study arms; however, rates were not significantly different among residents who received and did not receive a one-off structured medication regimen simplification intervention.

Unmet Needs for Transdermal Patch Management in Electronic Medication Administration Records: An Analysis of Data from 66 Aged Care Facilities

BACKGROUND

Transdermal medication patches have caused serious adverse events in residential aged care facilities (RACFs). Preliminary research suggests that facilities are using a workaround consisting of manually entered reminders in their electronic medication administration records (eMARs) to prompt staff to check and remove patches, because the eMAR does not support these tasks. However, the prevalence and factors associated with use of this workaround among facilities is unknown.

OBJECTIVES

The objectives of this study were to (1) examine the frequency and consistency with which manual reminders to check and remove transdermal patches were used in facility eMARs, and (2) identify resident and facility factors associated with reminder use, to inform eMAR redesign.

METHODS

This was a retrospective cross-sectional analysis of eMAR data from 66 Australian RACFs including 4,787 permanent residents, aged ≥65 years in January 2017. Prevalence of the use of reminders to check and remove patches, and consistency in their application within facilities were examined. Generalized estimating equations were used to determine factors associated with use of manual reminders.

RESULTS

One in five (n = 937) residents used a patch, and 83.6% of patches contained opioids, a high-risk medicine. 56.9% of facilities implemented manually entered check patch reminders in the eMAR, and 72.3% implemented remove reminders. The reminders were applied inconsistently, with only half of these facilities having reminders for all residents with patches. Residents in facilities in regional areas were more likely to have a check reminder compared with those in major cities (adjusted odds ratio = 4.72 [95% confidence interval: 1.69-13.20]).

CONCLUSION

Transdermal patches containing high-risk medicines are frequently used in RACFs, but their safe administration is not supported by a widely implemented eMAR. The frequent, but inconsistent use of a workaround to manually enter reminders indicates an unmet need for new eMAR functionality to improve safety.

Development of an algorithm to detect and reduce complexity of drug treatment and its technical realisation

Background

The increasing complexity of current drug therapies jeopardizes patient adherence. While individual needs to simplify a medication regimen vary from patient to patient, a straightforward approach to integrate the patients’ perspective into decision making for complexity reduction is still lacking. We therefore aimed to develop an electronic, algorithm-based tool that analyses complexity of drug treatment and supports the assessment and consideration of patient preferences and needs regarding the reduction of complexity of drug treatment.

Methods

Complexity factors were selected based on literature and expert rating and specified for integration in the automated assessment. Subsequently, distinct key questions were phrased and allocated to each complexity factor to guide conversation with the patient and personalize the results of the automated assessment. Furthermore, each complexity factor was complemented with a potential optimisation measure to facilitate drug treatment (e.g. a patient leaflet). Complexity factors, key questions, and optimisation strategies were technically realized as tablet computer-based application, tested, and adapted iteratively until no further technical or content-related errors occurred.

Results

In total, 61 complexity factors referring to the dosage form, the dosage scheme, additional instructions, the patient, the product, and the process were considered relevant for inclusion in the tool; 38 of them allowed for automated detection. In total, 52 complexity factors were complemented with at least one key question for preference assessment and at least one optimisation measure. These measures included 29 recommendations for action for the health care provider (e.g. to suggest a dosage aid), 27 training videos, 44 patient leaflets, and 5 algorithms to select and suggest alternative drugs.

Conclusions

Both the set-up of an algorithm and its technical realisation as computer-based app was successful. The electronic tool covers a wide range of different factors that potentially increase the complexity of drug treatment. For the majority of factors, simple key questions could be phrased to include the patients’ perspective, and, even more important, for each complexity factor, specific measures to mitigate or reduce complexity could be defined.

Patient safety incidents involving transdermal opioids: data from the Danish Patient Safety Database

Background Transdermal opioids are widely used among elderly adults with chronic pain. However, transdermal patches may be involved in a significant proportion of opioid-related patient safety incidents, as the application process includes several subprocesses, each associated with an individual risk of error. Objective The aim was to obtain specific knowledge on patient safety incidents related to transdermal opioid treatment within both the primary care sector and the hospital sector in Denmark. Setting The study is descriptive with data provided by the Danish Patient Safety Database. Methods We manually retrieved all patient safety incidents concerning transdermal opioids reported for 2018 from (1) the hospital sector and (2) the primary care sector. Study data were collected and managed using REDCap electronic data capture tools. Main outcome measure The available information for each incident was sorted into the following categories: location, medication process, type of problem, outcome at time of reporting, and outcome classification. Results A total of 866 patient safety incidents involving transdermal opioids were reported to the Danish Patient Safety Database in 2018. No fatal incidents were present in the database. In 386 cases, the incidents were reported as harmful, and these 386 cases were analysed. Most reports came from the primary care sector (nursing home, home care or social housing). The majority of incidents were related to the administration of the patch in the medication process, and the most prevalent problem was the omission of doses. Conclusion This study has demonstrated that the administration of transdermal opioids is challenging and may cause harm, particularly in the primary care sector. To improve patient safety, optimized systems, including guidelines on drug management and the continuing education of healthcare personnel in transdermal opioid management, are necessary. These guidelines should preferably incorporate reminders and checklists, since the omission of doses was the most reported problem.

Individual factors increasing complexity of drug treatment-a narrative review

Purpose

Complexity of drug treatment is known to be a risk factor for administration errors and nonadherence promoting higher healthcare costs, hospital admissions and increased mortality. Number of drugs and dose frequency are parameters often used to assess complexity related to the medication regimen. However, factors resulting from complex processes of care or arising from patient characteristics are only sporadically analyzed. Hence, the objective of this review is to give a comprehensive overview of relevant, patient-centered factors influencing complexity of drug treatment.

Methods

A purposeful literature search was performed in MEDLINE to identify potential complexity factors relating to the prescribed drug (i.e. dosage forms or other product characteristics), the specific medication regimen (i.e. dosage schemes or additional instructions), specific patient characteristics and process characteristics. Factors were included if they were associated to administration errors, nonadherence and related adverse drug events detected in community dwelling adult patients.

Results

Ninety-one influencing factors were identified: fourteen in “dosage forms”, five in “product characteristics”, twelve in “dosage schemes”, nine in “additional instructions”, thirty-one in “patient characteristics” and twenty in “process characteristics”.

Conclusions

Although the findings are limited by the non-systematic search process and the heterogeneous results, the search shows the influence of many factors on the complexity of drug treatment. However, to evaluate their relevance for individual patients, prospective studies are necessary.

[Simplifying complex drug therapies : Challenges and solutions]

The difficulties of managing a complex medication regimen are often underestimated in outpatient care. A large number of drugs (polypharmacy) and complicated dosage schemes or dosage forms may overstrain patients. Indeed, wrong drug administration can impair treatment success or cause adverse drug events.Patients are often unaware of the medication administration errors. Furthermore they do not voice administration problems, often because they are not aware of the potential to optimize their drug therapy. Medication regimen complexity can often be reduced by simple measures. However, feasible concepts for reducing medication regimen complexity in a structured way have been lacking in routine care so far.Electronic decision support facilitates systematic and efficient identification of factors that increase the complexity of a medication regimen. Furthermore, electronic decision aids may enable physicians and pharmacists to take appropriate measures in order to reduce medication regimen complexity. Personalizing the analysis and resulting measures to reduce medication regimen complexity might increase readiness of patients to implement changes in treatment and, thus, probably increase adherence. The first results of a prospective trial that is supported by the Federal Joint Committee (G-BA) Innovationsfonds (HIOPP-6, Komplexitätsreduktion in der Polypharmazie unter Beachtung von Patientenpräferenzen) will be available in autumn 2018 and answer these questions.

Construction and validation of a distance Basic Life Support Course

ABSTRACT Objective: to describe the content construction and validation process of the Distance Education Basic Life Support Course. Method: methodological study, developed through literature review, outlined in the light of the Bloom's Taxonomy and Ausubel's Meaningful Learning Theory. For validation, the analysis was performed with judges, using a structured tool. Results: the construction of the distance course was complex and challenging, since it was tried to develop it with logical-methodological coherence, considering the constructivist perspective, representing an advance in the process of dissemination of the Urgency and Emergency teaching culture. As for the content validation process, it was verified that of the 16 suggestions made by the judges, 14 were accepted and two rejected. Conclusion: the course had its contents validated by experts.

Poor adhesion of fentanyl transdermal patches may mimic end-of-dosage failure after 48 hours and prompt early patch replacement in hospitalized cancer pain patients

Context

Renewal of fentanyl transdermal patch (transdermal therapeutic system [TTS]) should occur every 3 days (72 hours) according to manufacturer’s guidelines. Some studies mentioned patients reporting end-of-dose failure, and thus, some authors recommend shortening the interval of application to 2 days (48 hours). However, reasons for early replacement are mostly unknown.

Objectives

The objectives of this study were to assess the prevalence of early replacement of fentanyl TTS in a cancer center in Basel, Switzerland, and to assess the reasons for early replacement in stationary patients.

Methods

We retrieved all fentanyl TTS administered in a cancer center in Basel, Switzerland, between November 11, 2011, and January 31, 2015, from the electronic medical database.

Results

A total of 739 patients (mean age 71.4±11.5 years, 55% women) were administered 2,250 fentanyl TTS (dosage 6–500 µg/hour). Most replacements occurred after 72 hours (61.6%) and a few after 48 hours (7.4%). Patients with early replacement after 48 hours were significantly younger (63.8 years versus 71.5 years, p<0.001) and obtained higher mean dosages of fentanyl TTS (89 µg/hour versus 44.1 µg/hour, p<0.001) and rescue medication (calculated as oral morphine equivalent in milligrams: 185.1 mg versus 39.6 mg during the first 24 hours after replacement, p<0.001). No pharmacological rationale for early replacement was observed. According to 57 physicians, nurses, and pharmacists, the most often reasons for early TTS replacement were end-of-dosage pain (41.4%) and poor adhesion (31.4%).

Conclusion

In the absence of any physiological, pharmacological, or environmental reasons recorded in the database to explain an early replacement of fentanyl TTS, skin adhesion problems may point practical reasons and mimic end-of-dosage failure.

Guidance on how to achieve comprehensible patient information leaflets in four steps

Comprehensible information leaflets can improve a patient's knowledge. However, in clinical studies leaflets are often introduced without meticulously verifying their comprehensibility. In an attempt to provide a feasible guidance on how to design comprehensible leaflets we complied and evaluated an easy-to-use development procedure. In January 2015, a literature search was performed to identify evidence for readily available quality assurance strategies as a starting point for a standardized strategy to develop and validate written patient information. The suggested development strategy is a consecutive four-step procedure that comprised already validated distinct quality assessments: (i) an initial requirement analysis specifying the needs and constraints of the target population and evidence-based preparation of the leaflets, (ii) a readability assessment, (iii) the Suitability Assessment of Materials instrument and (iv) iterative consumer test in the target population. The consecutive combination of pertinent and previously validated quality assessments provides an easy-to-use guidance on how to create comprehensibly written patient information, particularly for small-scale research projects with time and money constraints.
