Implementation of a pragmatic emergency department patients' own medications (POM) procedure to improve medication safety: An interrupted time series

BACKGROUND

Patients' Own Medications (POMs) are useful to inform clinical decision-making, best possible medication history documentation, and ensure timely medication administration. A procedure was developed for managing POMs specifically in the emergency department (ED) and short stay unit. This study evaluated the impact of this procedure on process and patient safety outcomes.

METHODS

An interrupted time-series was undertaken in a metropolitan ED/short stay unit between November 2017 and September 2021. Pre-implementation and during each of four post-implementation time-periods, data were collected at unannounced times on approximately 100 patients taking medications prior to presentation. Endpoints included proportion of patients with POMs stored in green POMs bags, in standardised locations, and proportion who self-medicated without nurses knowing.

RESULTS

Following procedure implementation, POMs were stored in standardised locations for 45.9 % of patients. Proportion of patients with POMs stored in green bags increased from 6.9 % to 48.2 % (difference 41.3 %, p < 0.001). Patient self-administration without nurses' knowledge declined from 10.3 % to 2.3 % (difference 8.0 %, p = 0.015). POMs were infrequently left in ED/short stay unit after discharge.

CONCLUSIONS

The procedure has standardised POMs storage, but room for further improvement remains. Although POMs were not locked away and were readily available to clinicians, patient self-medication without nurses' knowledge declined.

Promoting veterinary medication safety - Exploring the competencies of community pharmacy professionals in veterinary pharmacotherapy

The science of veterinary medicine is currently lacking studies on medication safety, although its importance in protecting animals from medication errors is central. Pharmacy professionals have an important role in ensuring medication safety of both prescription and over-the-counter medications of animals. However, this requires adequate competencies of pharmacy professionals in veterinary pharmacotherapy. The present study aimed to explore the competencies of pharmaceutical staff in community pharmacies in veterinary pharmacotherapy, which factors influence these competencies and what kind of information sources they typically use on veterinary pharmacotherapy. The study was conducted as a cross-sectional online survey targeted to pharmacy professionals in the Finnish community pharmacies, providing 596 responses. Less than half of the respondents (41%, n = 246) are considered to possess good competencies in veterinary pharmacotherapy. A third of the respondents (35%, n = 211) would dispense an anti-inflammatory drug for an animal off-label, whereas 24% (n = 145) would not interview the pet owner to discover the need for internal parasite medication before dispensing the drug. A small proportion (<1%, n = 5) would have dispensed a broad-spectrum internal parasite medication. Approximately a quarter of the respondents (27%, n = 159) stated that they acquired information on pharmacotherapy only from the material produced by the manufacturers of veterinary drugs. The competencies of pharmacy professionals in veterinary pharmacotherapy need to be strengthened in many areas to better promote veterinary medication safety. It should also be ensured that pharmacy professionals can access and use independent, high-quality information on veterinary pharmacotherapy.

Measuring health professionals' perceptions of communication contributing to medication incidents in hospitals - scale development and primary results of weekly perceived communication challenges

BACKGROUND

Communication challenges are one of the main contributors for medication incidents in hospitals, but health professionals' perceptions about variety of the contributing communication factors and the factors' occurrence frequencies are studied little. This cross-sectional descriptive study aimed to (1) operationalize a literature-based framework into a scale for measuring health professionals' perceptions of communication factors, which contribute to medication incidents either directly or indirectly in hospitals, (2) to measure the construct validity and internal consistency of the scale and (3) to describe the primary results of the measured weekly perceived communication challenges.

METHODS

The structured online questionnaire with 82 communication related items was developed based on a framework in literature. A content validity index of expert panelists' answers was used for item reduction. Data was collected between November 1st, 2019, and January 31st, 2020, by convenience sampling. The study sample (n = 303) included multiple health professional groups in diverse specialties, unit types and organizational levels in two specialized university hospital districts in Finland. Exploratory factor analysis with Maximum Likelihood method and Oblique rotation produced a six factors scale consisting of 57 items and having acceptable construct validity and internal consistency.

RESULTS

The six communication factors contributing to medication incidents concerned (1) medication prescriptions, (2) guidelines and reporting, (3) patient and family, (4) guideline implementation,5) competencies and responsibilities, and 6) attitude and atmosphere. The most frequently perceived communication challenges belonged to the Medication prescription related factor. Detailed item frequencies suggested that the most usual weekly challenges were: (1) lack or unclarity of communication about medication prescriptions, (2) missing the prescriptions which were written outside of the regular physician-ward-rounds and (3) digital software restricting information transfer.

CONCLUSIONS

The scale can be used for determining the most frequent detailed communication challenges. Confirmatory factor analysis of the scale is needed with a new sample for the scale validation. The weekly perceived communication challenges suggest that interventions are needed to standardize prescribing documentation and to strengthen communication about prescriptions given outside of regular ward-rounds.

Mapping the Theoretical Domain Framework to the Consolidated Framework for Implementation Research: do multiple frameworks add value?

BACKGROUND

Implementation researchers often combine the Theoretical Domain Framework (TDF) and Consolidated Framework for Implementation Research (CFIR) in their studies. However there is some debate on the merits of using multiple frameworks-whether they contribute to results or provide superfluous analysis. Our recent research combined the TDF and CFIR to identify determinants to widespread incorporation of patient held medication lists (PHML) in healthcare practice. The aim of this report is to provide guidance on the use of the TDF and CFIR; by assessing the degree of overlap between the two frameworks in their application to interviews about PHML.

METHODS

Semi-structured telephone interviews were conducted with healthcare professionals (HCPs) and non HCPs (people taking multiple medicines and caregivers).Interview data were transcribed and analysed using the TDF and CFIR. Within paired domains substantial intersection/overlap across constructs and domains within the two frameworks was classified as > 75% of coding references, consistent intersection/overlap was defined as > 50% and ≤ 75%, average intersection/overlap was defined as ≤ 50% and > 25% and non-substantial intersection/overlap was classified as ≤ 25% of coding references.

RESULTS

Interview data were collected from 39 participants - 21 HCPs and 18 non HCPs. Mapping of TDF domains to CFIR domains/constructs identified key determinants in six TDF domains: Environmental context & resources, Beliefs about capabilities, Beliefs about consequences, Social influences, Behavioural regulation and Social/professional role & identity; and five CFIR domains: Intervention Characteristics, Outer Setting, Inner Setting, Characteristics of Individual and Process. A pattern of substantial intersection/overlap in coding emerged with broad TDF domains such as Environmental context & resources often linked to well-defined CFIR domains and constructs (e.g. design quality & packaging within Intervention Characteristics). Broad CFIR constructs such as knowledge & beliefs about intervention within Characteristics of Individuals also linked to more descriptive TDF domains like Beliefs about capabilities. In addition there was some unexpected non-substantial intersection/overlap in coding with the TDF domain Social influences less frequently linked to the CFIR Inner Setting domain and constructs such as networks and communications.

CONCLUSIONS

Identifying intersections/overlaps in coding between CFIR and TDF can assist interpretation of findings in implementation research. The strengths of each framework were exploited in a reciprocal process which provided more information to broad/poorly defined domains and enabled identification of implementation determinants and innovation determinants.

Effect of a targeted quality improvement education on opioid prescribing

BACKGROUND

The opioid epidemic is a serious social, economic and public health problem. This study was designed to evaluate the effectiveness of individual institutional opioid prescriber training on prescriber adherence to the Centers for Disease Control and Prevention (CDC's) guidelines for responsible opioid prescribing practices to treat acute pain.

METHODS

Opioid prescribing data were collected from an academic medical centre and its associated outpatient clinics. A baseline for opioid prescribing practices was collected for 2 years and 2 months prior to the planned intervention. Departments responsible for 5% or more of the total institutional opioid prescriptions were chosen to study in detail. A number of opioid prescriptions per department per day and their compliance with the maximum daily dose (MDD) recommendations put out by the CDC were determined.

INTERVENTION

The hospital administration implemented a mandatory opioid prescriber training as part of their standard annual provider education for all medical staff, who were all required to attest having read it and pass a quiz by 30 September 2019, which was chosen as the end date for the pre-intervention data. Data were analysed preintervention and postintervention to assess the effect of this intervention on opioid prescribing.

RESULTS

Overall opioid prescribing rates decreased by 18.3% and there were significant decreases in opioid prescribing rate in five out of the seven departments/divisions. Overall, there was a statistically significant decrease in the compliance with MDD before (71.3%) and after (67.3%) the intervention (4%, 95% CI 3.13% to 4.87% difference, p<0.001). Additionally, there were statistically significant increases in compliance with CDC guidelines in three departments/divisions. However, there was a statistically significant decrease in compliance with CDC guidelines after intervention in two departments.

CONCLUSIONS

The results of this study were largely encouraging for the effectiveness of this institutional mandatory prescriber training.

Rasburicase-induced hemolytic anemia and methemoglobinemia: a systematic review of current reports

Since the FDA's approval of rasburicase use for treatment of tumor lysis syndrome (TLS), multiple cases of rasburicase-induced methemoglobinemia and hemolytic anemia have been reported among patients with G6PD deficiency. This study aims to provide a systematic review of cases reporting such adverse reactions to rasburicase. A literature review of published cases in PubMed, Embase, Cochrane, and Web of Science was conducted. Descriptive studies reporting cases of rasburicase-induced methemoglobinemia and/or hemolytic anemia in English were analyzed and summarized in this study. Forty-three cases, including a case from our institution, were included in this study. Most cases (60.5%) received rasburicase for TLS treatment. Almost all patients (93.8%) were tested for G6PD after rasburicase administration. The median time to symptom onset was 24 h. The median methemoglobin level was 10%, peaking after a median of 24 h. The median hemoglobin nadir was 6.1 g/dL, and most patients (n = 32) required blood transfusion. Out of 39 cases with reported outcomes, 35 patients (89.7%) recovered, while four patients (three females and one male) died. The median time to recovery was 4.5 days while the median time to death was 8 days. Screening for G6PD deficiency among high-risk patients is important but not practical in acutely severe settings. When prior screening for G6PD deficiency is not feasible, close monitoring for methemoglobinemia and hemolytic anemia is recommended. Exchange transfusion is increasingly reported as a potentially successful therapeutic modality. Ascorbic acid may provide limited benefits. Methylene blue should be avoided as it may exacerbate hemolysis among these patients.

Cannabis dispensary staff approaches to counseling on potential contraindications to cannabis use: insights from a national self-report survey

BACKGROUND

Legal cannabis is available in more than half of the United States. Health care professionals (HCPs) rarely give recommendations on dosing or safety of cannabis due to limits imposed by policy and lack of knowledge. Customer-facing cannabis dispensary staff, including clinicians (pharmacists, nurses, physician's assistants), communicate these recommendations in the absence of HCP recommendations. Little is known about how dispensary staff approach individuals with complex medical and psychiatric comorbidities. Using responses from a national survey, we describe how cannabis dispensary staff counsel customers with medical and psychiatric comorbidities on cannabis use and examine whether state-specific cannabis policy is associated with advice given to customers.

METHODS

National, cross-sectional online survey study from February 13, 2020 to October 2, 2020 of dispensary staff at dispensaries that sell delta-9-tetrahydrocannabinol containing products. Measures include responses to survey questions about how they approach customers with medical and psychiatric comorbidities; state medicalization score (scale 0-100; higher score indicates more similarity to regulation of traditional pharmacies); legalized adult-use cannabis (yes/no). We conducted multiple mixed effects multivariable logistic regression analyses to understand relationships between state medicalization and dispensary employees' perspectives.

RESULTS

Of 434 eligible respondents, most were budtenders (40%) or managers (32%), and a minority were clinicians (18%). State medicalization score was not associated with responses to most survey questions. It was associated with increased odds of encouraging customers with medical comorbidities to inform their traditional HCP of cannabis use (Odds ratio [OR]=1.2, 95% confidence interval [CI] 1.0-1.4, p=0.03) and reduced odds of recommending cannabis for individuals with cannabis use disorder (CUD) (OR=0.8, 95% CI 0.7-1.0, p=0.04). Working in a state with legalized adult-use cannabis was associated with recommending traditional health care instead of cannabis in those with serious mental illness (OR 2.2, 95% CI 1.1-4.7, p=0.04). Less than half of respondents believed they had encountered CUD (49%), and over a quarter did not believe cannabis is addictive (26%).

CONCLUSIONS

When managing cannabis dosing and safety in customers with medical and psychiatric comorbidity, dispensary staff preferred involving individuals' traditional HCPs. Dispensary staff were skeptical of cannabis being addictive. While state regulations of dispensaries may impact the products individuals have access to, they were not associated with recommendations that dispensary staff gave to customers. Alternative explanations for dispensary recommendations may include regional or store-level variation not captured in this analysis.

Applicability of drug-related problem (DRP) classification system for classifying severe medication errors

BACKGROUND

Several classification systems for medication errors (MEs) have been established over time, but none of them apply optimally for classifying severe MEs. In severe MEs, recognizing the causes of the error is essential for error prevention and risk management. Therefore, this study focuses on exploring the applicability of a cause-based DRP classification system for classifying severe MEs and their causes.

METHODS

This was a retrospective document analysis study on medication-related complaints and authoritative statements investigated by the Finnish National Supervisory Authority for Welfare and Health (Valvira) in 2013-2017. The data was classified by applying a previously developed aggregated DRP classification system by Basger et al. Error setting and harm to the patient were identified using qualitative content analysis to describe the characteristics of the MEs in the data. The systems approach to human error, error prevention, and risk management was used as a theoretical framework.

RESULTS

Fifty-eight of the complaints and authoritative statements concerned MEs, which had occurred in a wide range of social and healthcare settings. More than half of the ME cases (52%, n = 30) had caused the patient's death or severe harm. In total, 100 MEs were identified from the ME case reports. In 53% (n = 31) of the cases, more than one ME was identified, and the mean number of MEs identified was 1.7 per case. It was possible to classify all MEs according to aggregated DRP system, and only a small proportion (8%, n = 8) were classified in the category "Other," indicating that the cause of the ME could not be classified to specific cause-based category. MEs in the "Other" category included dispensing errors, documenting errors, prescribing error, and a near miss.

CONCLUSIONS

Our study provides promising preliminary results for using DRP classification system for classifying and analyzing especially severe MEs. With Basger et al.'s aggregated DRP classification system, we were able to categorize both the ME and its cause. More research is encouraged with other ME incident data from different reporting systems to confirm our results.

Clinical pharmacist intervention to improve medication safety for hip fracture patients through secondary and primary care settings: a nonrandomised controlled trial

BACKGROUND

Hip fracture patients face a patient safety threat due to medication discrepancies and adverse drug reactions when they have a combination of high age, polypharmacy and several care transitions. Consequently, optimised pharmacotherapy through medication reviews and seamless communication of medication information between care settings is necessary. The primary aim of this study was to investigate the impact on medication management and pharmacotherapy. The secondary aim was to evaluate implementation of the novel Patient Pathway Pharmacist intervention for hip fracture patients.

METHODS

Hip fracture patients were included in this nonrandomised controlled trial, comparing a prospective intervention group (n = 58) with pre-intervention controls who received standard care (n = 50). The Patient Pathway Pharmacist intervention consisted of the steps: (A) medication reconciliation at admission to hospital, (B) medication review during hospitalisation, (C) recommendation for the medication information in the hospital discharge summary, (D) medication reconciliation at admission to rehabilitation, and (E) medication reconciliation and (F) review after hospital discharge. The primary outcome measure was quality score of the medication information in the discharge summary (range 0-14). Secondary outcomes were potentially inappropriate medications (PIMs) at discharge, proportion receiving pharmacotherapy according to guidelines (e.g. prophylactic laxatives and osteoporosis pharmacotherapy), and all-cause readmission and mortality.

RESULTS

The quality score of the discharge summaries was significantly higher for the intervention patients (12.3 vs. 7.2, p < 0.001). The intervention group had significantly less PIMs at discharge (- 0.44 (95% confidence interval - 0.72, - 0.15), p = 0.003), and a higher proportion received prophylactic laxative (72 vs. 35%, p < 0.001) and osteoporosis pharmacotherapy (96 vs. 16%, p < 0.001). There were no differences in readmission or mortality 30 and 90 days post-discharge. The intervention steps were delivered to all patients (step A, B, E, F = 100% of patients), except step (C) medication information at discharge (86% of patients) and step (D) medication reconciliation at admission to rehabilitation (98% of patients).

CONCLUSION

The intervention steps were successfully implemented for hip fracture patients and contributed to patient safety through a higher quality medication information in the discharge summary, fewer PIMs and optimised pharmacotherapy.

Understanding the medication safety challenges for patients with mental illness in primary care: a scoping review

BACKGROUND

Mental illness and medication safety are key priorities for healthcare systems around the world. Despite most patients with mental illness being treated exclusively in primary care, our understanding of medication safety challenges in this setting is fragmented.

METHOD

Six electronic databases were searched between January 2000-January 2023. Google Scholar and reference lists of relevant/included studies were also screened for studies. Included studies reported data on epidemiology, aetiology, or interventions related to medication safety for patients with mental illness in primary care. Medication safety challenges were defined using the drug-related problems (DRPs) categorisation.

RESULTS

Seventy-nine studies were included with 77 (97.5%) reporting on epidemiology, 25 (31.6%) on aetiology, and 18 (22.8%) evaluated an intervention. Studies most commonly (33/79, 41.8%) originated from the United States of America (USA) with the most investigated DRP being non-adherence (62/79, 78.5%). General practice was the most common study setting (31/79, 39.2%) and patients with depression were a common focus (48/79, 60.8%). Aetiological data was presented as either causal (15/25, 60.0%) or as risk factors (10/25, 40.0%). Prescriber-related risk factors/causes were reported in 8/25 (32.0%) studies and patient-related risk factors/causes in 23/25 (92.0%) studies. Interventions to improve adherence rates (11/18, 61.1%) were the most evaluated. Specialist pharmacists provided the majority of interventions (10/18, 55.6%) with eight of these studies involving a medication review/monitoring service. All 18 interventions reported positive improvements on some medication safety outcomes but 6/18 reported little difference between groups for certain medication safety measures.

CONCLUSION

Patients with mental illness are at risk of a variety of DRPs in primary care. However, to date, available research exploring DRPs has focused attention on non-adherence and potential prescribing safety issues in older patients with dementia. Our findings highlight the need for further research on the causes of preventable medication incidents and targeted interventions to improve medication safety for patients with mental illness in primary care.

Geriatric Syndromes in Older Adults with Diabetes

Over one-quarter of adults ≥65 years old have diabetes in the United States. Guidelines recommend individualization of glycemic targets in older adults with diabetes as well as implementing treatment strategies that minimize risk for hypoglycemia. Patient-centered management decisions should be informed by comorbidities, the individual's capacity for self-care, and the presence of key geriatric syndromes that may impact self-management and patient safety. Key geriatric syndromes include cognitive impairment, depression, functional impairments (eg, vision, hearing, and mobility challenges), falls and fractures, polypharmacy, and urinary incontinence. Screening for geriatric syndromes in older adults is recommended to inform treatment strategies and optimize outcomes.

Impact of a quality improvement programme on the preparation and administration of medications via a nasoenteral feeding tube: 2014-2019 intervention study

AIMS

Evaluate the impact of a quality improvement programme on the reduction of feeding tube obstruction frequencies, analyse the predictive variables of this safety incident, and estimate the economic costs related to the quality improvement programme during the period from 2014 to 2019.

METHODS

Plan-Do-Study-Act cycles were performed to test the changes in drug preparation and administration processes via a nasoenteral feeding tube and to evaluate the outcome, process and balance measures. Statistical control charts were elaborated, and the bottom-up direct costing methodology was used to estimate the costs of the improvement programme. The impact of the programme on the monitoring measures was evaluated using logistic regression analysis.

INTERVENTIONS

The following changes were tested in the hospital participating in the study: acquisition of the Easy Crush equipment for tablet crushing, use of appropriate packaging to crush hard tablets, standardise procedures for scheduling administration times and/or substitution of the pharmaceutical form, educational activities for the nursing team and elaboration and availability of infographics for the nursing team, patients and/or family/caregivers.

RESULTS

There was a significant improvement in the frequency of tube obstructions, from 41.1% in 2014 to 57.9% in 2015-2017 and 9.6% in 2018-2019 (p=0.0010). After the execution of the improvement programme, it was estimated that the cost of dose preparation was reduced from R$1067.50 in 2014 to R$719.80 in 2015-2017 and R$433.10 in 2015-2019.

CONCLUSION

By re-establishing the processes of drug preparation and administration via a nasoenteral feeding tube, through the acquisition of appropriate equipment for crushing hard tablets, together with educational activities for the nursing team, we could observe a reduction in tube obstructions and the cost of processes.

Implementation of medication reconciliation at admission and discharge in Ministry of Defense Health Services hospitals: a multicentre study

There is potential for many medication errors to occur due to the complex medication use process. The medication reconciliation process can significantly lower the incidence of medication errors that may arise from an incomplete or inaccurate medication history as well as reductions in length of hospital stay, patients' readmissions and lower healthcare costs.The quality improvement collaborative project was conducted as a pilot study in two hospitals, then implemented on a broader scale in 18 hospitals in Saudi Arabia. The goal of the project was to reduce the percentage of patients with at least one outstanding unintentional discrepancy at admission by 50%, over 16-month period (July 2020-November 2021). Our interventions were based on the High 5's project medication reconciliation WHO, and Medications at Transitions and Clinical Handoffs toolkit for medication reconciliation by Agency for Healthcare Research and Quality. Improvement teams used the Institute of Healthcare Improvement's (IHI's) Model for improvement as a tool for testing and implementing changes. Collaboration and learning between hospitals were facilitated by conducting learning sessions using the IHI's Collaborative Model for Achieving Breakthrough Improvement. The improvement teams underwent three cycles.By the end of the project significant improvements were observed. The percentage of patients with at least one outstanding unintentional discrepancy at admission showed a 20% reduction (27% before, 7% after; p value <0.05) (Relative Risk (RR) 0.74) with a mean reduction in the number of discrepancies per patient by 0.74. The percentage of patients with at least one outstanding unintentional discrepancy at discharge showed 12% reduction (17% before, 5% after; p value <0.05) (RR 0.71) with a mean reduction in the number of discrepancies per patient by 0.34.Compliance to medication reconciliation documentation within 24 hours of admission and discharge showed significant improvement by an average of 17% and 24%, respectively. Additionally, the implementation of medication reconciliation had a negative correlation with the percentage of patients with at least one outstanding unintentional discrepancy at admission and discharge.

Assessment of knowledge, attitude, and practices of acute kidney injury incidence with co-administration of piperacillin/tazobactam and vancomycin among healthcare workers: A cross-sectional study

Background

No studies have identified a link between acute kidney injury (AKI) incidence due to the co-administration of vancomycin and piperacillin/tazobactam (VPT) and healthcare providers' knowledge, attitudes, and practices. We aimed to (1) assess the knowledge, attitudes, and practices towards AKI due to VPT co-administration among healthcare providers in Saudi Arabia, and (2) examine the relationship between healthcare providers' knowledge and attitudes about AKI due to VPT co-administration and their practices.

Methods

This cross-sectional study was conducted between February 2022 and April 2022. Healthcare providers, including physicians, pharmacists, and nurses, were included in the study population. The correlation coefficient assessed the relationship between knowledge, attitude, and practice. Spearman's rho was used as a test statistic.

Results

Of the invited healthcare providers, 192 responded to the survey. A significant difference in knowledge was found among healthcare providers for two variables: the definition of AKI (p < 0.001) and appropriate management of AKI due to VPT (p = 0.002). Physicians were found to rely less on the most common causative organisms of infection to guide empirical antibiotic therapy (p < 0.001). In addition, physicians were less likely to switch piperacillin/tazobactam to cefepime or meropenem in combination with vancomycin with AKI incidence (p = 0.001). A positive attitude towards the perceived AKI risk with VPT was positively correlated with avoiding using VPT unless no alternatives were available (Rho = 0.336) and taking protective measures when using VPT (Rho = 0.461).

Conclusion

Deviation has been observed in the knowledge, attitudes, and practices of AKI incidence with the co-administration of piperacillin/tazobactam and vancomycin among healthcare workers. Interventions at the organizational level are recommended to guide best practices.

Assessment of knowledge, cultural beliefs, and behavior regarding medication safety among residents in Harbin, China

BACKGROUND

Medication misuse or overuse is significantly associated with poor health outcomes. Information regarding the knowledge, cultural beliefs, and behavior about medication safety in the general population is important.

AIM

To conduct a survey on medication habits and explored the potential factors impacting medication safety.

METHODS

The current survey included adults from 18 districts and counties in Harbin, China. A questionnaire on medication safety was designed based on knowledge, cultural beliefs, and behavior. Both univariate and multivariate analyses were used to explore the factors that impacted medication safety.

RESULTS

A total of 394 respondents completed the questionnaires on medication safety. The mean scores for knowledge, cultural beliefs, and behavior about medication safety were 59.41 ± 19.33, 40.66 ± 9.24, and 60.97 ± 13.69, respectively. The medication knowledge score was affected by age (P = 0.044), education (P < 0.001), and working status (P = 0.015). Moreover, the cultural beliefs score was significantly affected by education (P < 0.001). Finally, education (P = 0.003) and working status (P = 0.011) significantly affected the behavior score.

CONCLUSION

The knowledge, cultural beliefs, and behavior about medication safety among the general population was moderate. Health education should be provisioned for the elderly, individuals with a low education level, and the unemployed to improve medication safety in Harbin, China.

Improvement in Pharmacy Student Responses to Medication-Related Problems with and without Clinical Decision Support Alerts

OBJECTIVE

To assess pharmacy student responses to medication problems with and without clinical decision support (CDS) alerts during simulated order verification.

METHODS

Three classes of students completed an order verification simulation. The simulation randomized students to a different series of 10 orders with varying CDS alert frequency. Two of the orders contained medication-related problems. The appropriateness of the students' interventions and responses to the CDS alerts were evaluated. In the following semester for 2 classes, 2 similar simulations were completed. All 3 simulations contained 1 problem with and 1 without an alert.

RESULTS

During the first simulation, 384 students reviewed an order with a problem and an alert. Students exposed to prior inappropriate alerts within the simulation had less appropriate responses (66% vs 75%). Of 321 students who viewed a second order with a problem, those reviewing an order lacking an alert recommended an appropriate change less often (45% vs 87%). Among 351 students completing the second simulation, those who participated in the first simulation appropriately responded to the alert for a problem more often than those who only received a didactic debrief (95% vs 87%). Among those completing all 3 simulations, appropriate responses increased between simulations for problems with (n = 238, 72-95-93%) and without alerts (n = 49, 53-71-90%).

CONCLUSIONS

Some pharmacy students displayed baseline alert fatigue and overreliance on CDS alerts for medication problem detection during order verification simulations. Exposure to the simulations improved CDS alert response appropriateness and detection of problems.

Implementation of barcode medication administration (BMCA) technology on infusion pumps in the operating rooms

BACKGROUND

Medication administration errors (MAEs) are a major cause of morbidity and mortality. An updated barcode medication administration (BCMA) technology on infusion pumps is implemented in the operating rooms to automate double check at a syringe exchange.

OBJECTIVE

The aim of this mixed-methods before-and-after study is to understand the medication administrating process and assess the compliance with double check before and after implementation.

METHODS

Reported MAEs from 2019 to October 2021 were analysed and categorised to the three moments of medication administration: (1) bolus induction, (2) infusion pump start-up and (3) changing an empty syringe. Interviews were conducted to understand the medication administration process with functional resonance analysis method (FRAM). Double check was observed in the operating rooms before and after implementation. MAEs up to December 2022 were used for a run chart.

RESULTS

Analysis of MAEs showed that 70.9% occurred when changing an empty syringe. 90.0% of MAEs were deemed to be preventable with the use of the new BCMA technology. The FRAM model showed the extent of variation to double check by coworker or BCMA.Observations showed that the double check for pump start-up changed from 70.2% to 78.7% postimplementation (p=0.41). The BCMA double check contribution for pump start-up increased from 15.3% to 45.8% (p=0.0013). The double check for changing an empty syringe increased from 14.3% to 85.0% (p<0.0001) postimplementation. BCMA technology was new for changing an empty syringe and was used in 63.5% of administrations. MAEs for moments 2 and 3 were significantly reduced (p=0.0075) after implementation in the operating rooms and ICU.

CONCLUSION

An updated BCMA technology contributes to a higher double check compliance and MAE reduction, especially when changing an empty syringe. BCMA technology has the potential to decrease MAEs if adherence is high enough.

Patient perceptions and experiences with medication-related activities in the emergency department: a qualitative study

BACKGROUND

Emergency department (ED) pharmacists reduce medication errors and improve quality of medication use. Patient perceptions and experiences with ED pharmacists have not been studied. The aim of this study was to explore patients' perceptions of and experiences with medication-related activities in the ED, with and without an ED pharmacist present.

METHODS

We conducted 24 semistructured individual interviews with patients admitted to one ED in Norway, 12 before and 12 during an intervention, where pharmacists performed medication-related tasks close to patients and in collaboration with ED staff. Interviews were transcribed and analysed applying thematic analysis.

RESULTS

From our five developed themes, we identified that: (1) Our informants had low awareness and few expectations of the ED pharmacist, both with and without the pharmacist present. However, they were positive to the ED pharmacist. (2) Our informants expressed a variation of trust in the healthcare system, healthcare professionals and electronic systems, though the majority expressed a high level of trust. They believed that their medication list was automatically updated and assumed to get the correct medication. (3) Some informants felt responsible to have an overview of their medication use, while others expressed low interest in taking responsibility regarding their medication. (4) Some informants did not want involvement from healthcare professionals in medication administration, while others expressed no problems with giving up control. (5) Medication information was important for all informants to feel confident in medication use, but the need for information differed.

CONCLUSION

Despite being positive to pharmacists, it did not seem important to our informants who performed the medication-related tasks, as long as they received the help they needed. The degree of trust, responsibility, control and information varied among ED patients. These dimensions can be applied by healthcare professionals to tailor medication-related activities to patients' individual needs.

A coordinated approach for managing polypharmacy among children with medical complexity: rationale and design of the Pediatric Medication Therapy Management (pMTM) randomized controlled trial

BACKGROUND

Children with medical complexity (CMC) often rely upon the use of multiple medications to sustain quality of life and control substantial symptom burden. Pediatric polypharmacy (≥ 5 concurrent medications) is prevalent and increases the risk of medication-related problems (MRPs). Although MRPs are associated with pediatric morbidity and healthcare utilization, polypharmacy is infrequently assessed during routine clinical care for CMC. The aim of this randomized controlled trial is to determine if a structured pharmacist-led Pediatric Medication Therapy Management (pMTM) intervention reduces MRP counts, as well as the secondary outcomes of symptom burden and acute healthcare utilization.

METHODS

This is a hybrid type 2 randomized controlled trial assessing the effectiveness of pMTM compared to usual care in a large, patient-centered medical home for CMC. Eligible patients include all children ages 2-18 years old, with ≥ 1 complex chronic condition, and with ≥ 5 active medications, as well as their English-speaking primary caregivers. Child participants and their primary parental caregivers will be randomized to pMTM or usual care before a non-acute primary care visit and followed for 90 days. Using generalized linear models, the overall effectiveness of the intervention will be evaluated using total MRP counts at 90 days following pMTM intervention or usual care visit. Following attrition, a total of 296 CMC will contribute measurements at 90 days, which provides > 90% power to detect a clinically significant 1.0 reduction in total MRPs with an alpha level of 0.05. Secondary outcomes include Parent-Reported Outcomes of Symptoms (PRO-Sx) symptom burden scores and acute healthcare visit counts. Program replication costs will be assessed using time-driven activity-based scoring.

DISCUSSION

This pMTM trial aims to test hypotheses that a patient-centered medication optimization intervention delivered by pediatric pharmacists will result in lower MRP counts, stable or improved symptom burdens, and fewer cumulative acute healthcare encounters at 90 days following pMTM compared to usual care. The results of this trial will be used to quantify medication-related outcomes, safety, and value for a high-utilization group of CMC, and outcomes may elucidate the role of integrated pharmacist services as a key component of outpatient complex care programs for this priority pediatric population.

Knowledge, attitude, behaviour, and influencing factors of home-based medication safety among community-dwelling older adults with chronic diseases: a cross-sectional study

BACKGROUND

Older adults with chronic diseases require long-term medication. However, due to lack of drug knowledge and hypomnesia, older adults with chronic diseases are prone to adverse drug events and increased medical costs. This study aimed to explore the status and influencing factors of home-based medication safety among community-dwelling older adults with chronic diseases in China to provide a basis for follow-up to conduct targeted health education.

METHODS

Overall, 427 community-dwelling older adults with chronic diseases participated in this study. The Knowledge, Attitude, and Behaviour of Medication Safety among Older Adults with Chronic Diseases Questionnaire was used to assess their home-based medication safety. Multivariate linear regression was used to identify the factors influencing knowledge, attitude, and behaviour regarding medication safety.

RESULTS

The average score of home-based medication safety among older adults with chronic diseases was 68.26 ± 8.96, indicating that they had a moderate grasp of medication safety. The scoring rate of each subscale was ranked from high to low as follows: behaviour (84.51%), knowledge (63.33%), and attitude (47.39%). Stepwise linear regression analysis showed that medication safety knowledge, attitudes, and behaviours were significantly associated with higher monthly income, adverse drug events, and taking medicine several times a day (p < 0.05). Additional influencing factors included having fewer chronic diseases, being female, higher educational attainment, taking medicines multiple kinds a day, better self-care ability, and non-hospitalisation for chronic illnesses (p < 0.05).

CONCLUSION

Medical staff and community workers should pay attention to the drug safety of older adults with different characteristics and mobilise their enthusiasm for participation to improve their medication self-management ability.

Sulfonylureas as second line therapy for type 2 diabetes among veterans: Results from a National Longitudinal Cohort Study

AIMS

To assess if switching to or adding sulfonylureas increases major adverse cardiovascular events (MACE) or severe hypoglycemia versus remaining on metformin alone.

MATERIALS AND METHODS

This was a retrospective, longitudinal cohort utilizing United States Veterans Health Administration and Medicare data. Veterans with type 2 diabetes on metformin monotherapy between 2004 and 2006 were identified. Follow-up occurred through 2016. Those treated with either metformin plus a second-generation sulfonylurea (N = 45,305) or converted from metformin to a second-generation sulfonylurea (N = 2813) were compared to those receiving metformin monotherapy (N = 65,550). Hazard ratios (HR) and 95%CI from longitudinal competing risk Cox models were used to measure the association between sulfonylureas and outcomes.

RESULTS

Switching to or adding a sulfonylurea to metformin was associated with 3 times the risk of severe hypoglycemia versus metformin monotherapy (HR:3.44, 95% CI: 3.06,3.85 and HR: 3.08, 95% CI: 2.77,3.42, respectively). Switching to or adding a sulfonylurea to metformin was associated with a 7-19% higher risk of MACE versus metformin monotherapy (HR: 1.07, 95% CI: 1.00,1.14 and HR: 1.19, 95% CI: 1.13,1.25, respectively).

CONCLUSIONS

Switching to and adding second-generation sulfonylureas was associated an increase in severe hypoglycemia and MACE versus remaining on metformin alone. In an era where guidelines recommend diabetes therapies based on compelling indications, safety outcomes should be a key consideration when selecting therapy.

Barriers and facilitators to improving patient safety learning systems: a systematic review of qualitative studies and meta-synthesis

BACKGROUND

The implementation and continuous improvement of patient safety learning systems (PSLS) is a principal strategy for mitigating preventable harm to patients. Although substantial efforts have sought to improve these systems, there is a need to more comprehensively understand critical success factors. This study aims to summarise the barriers and facilitators perceived by hospital staff and physicians to influence the reporting, analysis, learning and feedback within PSLS in hospitals.

METHODS

We performed a systematic review and meta-synthesis by searching MEDLINE (Ovid), EMBASE (Ovid), CINAHL, Scopus and Web of Science. We included English-language manuscripts of qualitative studies evaluating effectiveness of the PSLS and excluded studies evaluating specific individual adverse events, such as systems for tracking only medication side effects, for example. We followed the Joanna Briggs Institute methodology for qualitative systematic reviews.

RESULTS

We extracted data from 22 studies, after screening 2475 for inclusion/exclusion criteria. The included studies focused on reporting aspects of the PSLS, however, there were important barriers and facilitators across the analysis, learning and feedback phases. We identified the following barriers for effective use of PSLS: inadequate organisational support with shortage of resources, lack of training, weak safety culture, lack of accountability, defective policies, blame and a punitive environment, complex system, lack of experience and lack of feedback. We identified the following enabling factors: continuous training, a balance between accountability and responsibility, leaders as role models, anonymous reporting, user-friendly systems, well-structured analysis teams, tangible improvement.

CONCLUSION

Multiple barriers and facilitators to uptake of PSLS exist. These factors should be considered by decision makers seeking to enhance the impact of PSLS.

Medication-related Medical Emergency Team activations: a case review study of frequency and preventability

OBJECTIVES

Despite recognition of clinical deterioration and medication-related harm as patient safety risks, the frequency of medication-related Rapid Response System activations is undefined. We aimed to estimate the incidence and preventability of medication-related Medical Emergency Team (MET) activations and describe the associated adverse medication events.

METHODS

A case review study of consecutive MET activations at two acute, academic teaching hospitals in Melbourne, Australia with mature Rapid Response Systems was conducted. All MET activations during a 3-week study period were assessed for a medication cause including identification of the contributing adverse medication event and its preventability, using validated tools and recognised classification systems.

RESULTS

There were 9439 admissions and 628 MET activations during the study period. Of these, 146 (23.2%) MET activations were medication related: an incidence of 15.5 medication-related MET activation per 1000 admissions. Medication-related MET activations occurred a median of 46.6 hours earlier (IQR 22-165) in an admission than non-medication-related activations (p=0.001). Furthermore, this group also had more repeat MET activations during their admission (p=0.021, OR=1.68, 95% CI 1.09 to 2.59). A total of 92 of 146 (63%) medication-related MET activations were potentially preventable. Tachycardia due to omission of beta-blocking agents (10.9%, n=10 of 92) and hypotension due to cumulative toxicity (9.8%, n=9 of 92) or inappropriate use (10.9%, n=10 of 92) of antihypertensives were the most common adverse medication events leading to potentially preventable medication-related MET activations.

CONCLUSIONS

Medications contributed to almost a quarter of MET activations, often early in a patient's admission. One in seven MET activations were due to potentially preventable adverse medication events. The most common of these were omission of beta-blockers and clinically inappropriate antihypertensive use. Strategies to prevent these events would increase patient safety and reduce burden on the MET.

Development and application of Adverse drug reactions reports QUality Algorithm (AQUA-12) score: a single-centre quality improvement initiative

PURPOSE

To develop a reliable assessment tool to monitor the quality of adverse drug reaction (ADR) reports and evaluate its performance within a quaternary hospital setting.

METHODS

Adverse drug reactions report QUality Algorithm (AQUA-12) was developed by a multidisciplinary team with the expertise in the management of ADRs. The design was based on data elements required to establish medication causality. Inter-rater reliability of AQUA-12 was evaluated over three rounds in two phases: development and prospective evaluation phases, by independent assessors both internal and external to the institutional ADR review processes. The characteristics and quality of ADR reports were subsequently assessed, and potential factors contributing to low-quality reports were identified.

RESULTS

A total of 70 ADR reports were assessed, 20 in development and 50 in evaluation phases. The inter-rater reliability of AQUA-12 was found to be excellent in all three rounds (Cronbach's alpha of  ≥ 0.9, p < 0.001 for all). Approximately one in five reports concerned immediate hypersensitivity reactions while delayed hypersensitivity reactions constituted 60% of all reactions. AQUA-12 identified 18 (25.7%) reports as 'low-quality' with a score of  < 10. Identification of suspected medications (37.1%), description of index ADR (27.1%), and key events (ADR narrative, 35.7%) were the top data elements incomplete or missing from all reports. Univariable analyses identified the severity of the reaction as a factor associated with low quality of reports (p = 0.008).

CONCLUSIONS

AQUA-12 is a practical and highly reliable assessment tool that can be utilised in hospital settings to regularly monitor the completeness of ADR reports to guide quality improvement initiatives.
