Understanding Hazards for Adverse Drug Events Among Older Adults After Hospital Discharge: Insights From Frontline Care Professionals

Assessing patient work system factors for medication management during transition of care among older adults: an observational study

OBJECTIVE

To develop and evaluate measures of patient work system factors in medication management that may be modifiable for improvement during the care transition from hospital to home among older adults.

DESIGN, SETTINGS AND PARTICIPANTS

Measures were developed and evaluated in a multisite prospective observational study of older adults (≥65 years) discharged home from medical units of two US hospitals from August 2018 to July 2019.

MAIN MEASURES

Patient work system factors for managing medications were assessed during hospital stays using six capacity indicators, four task indicators and three medication management practice indicators. Main outcomes were assessed at participants' homes approximately a week after discharge for (1) Medication discrepancies between the medications taken at home and those listed in the medical record, and (2) Patient experiences with new medication regimens.

RESULTS

274 of the 376 recruited participants completed home assessment (72.8%). Among capacity indicators, most older adults (80.6%) managed medications during transition without a caregiver, 41.2% expressed low self-efficacy in managing medications and 18.3% were not able to complete basic medication administration tasks. Among task indicators, more than half (57.7%) had more than 10 discharge medications and most (94.7%) had medication regimen changes. Having more than 10 discharge medications, more than two medication regimen changes and low self-efficacy in medication management increased the risk of feeling overwhelmed (OR 2.63, 95% CI 1.08 to 6.38, OR 3.16, 95% CI 1.29 to 7.74 and OR 2.56, 95% CI 1.25 to 5.26, respectively). Low transportation independence, not having a home caregiver, low medication administration skills and more than 10 discharge medications increased the risk of medication discrepancies (incidence rate ratio 1.39, 95% CI 1.01 to 1.91, incidence rate ratio 1.73, 95% CI 1.13 to 2.66, incidence rate ratio 1.99, 95% CI 1.37 to 2.89 and incidence rate ratio 1.91, 95% CI 1.24 to 2.93, respectively).

CONCLUSIONS

Patient work system factors could be assessed before discharge with indicators for increased risk of poor patient experience and medication discrepancies during older adults' care transition from hospital to home.

Patient Partnership Tools to Support Medication Safety in Community-Dwelling Older Adults: Protocol for a Nonrandomized Stepped Wedge Clinical Trial

BACKGROUND

Preventable harms from medications are significant threats to patient safety in community settings, especially among ambulatory older adults on multiple prescription medications. Patients may partner with primary care professionals by taking on active roles in decisions, learning the basics of medication self-management, and working with community resources.

OBJECTIVE

This study aims to assess the impact of a set of patient partnership tools that redesign primary care encounters to encourage and empower patients to make more effective use of those encounters to improve medication safety.

METHODS

The study is a nonrandomized, cross-sectional stepped wedge cluster-controlled trial with 1 private family medicine clinic and 2 public safety-net primary care clinics each composing their own cluster. There are 2 intervention sequences with 1 cluster per sequence and 1 control sequence with 1 cluster. Cross-sectional surveys will be taken immediately at the conclusion of visits to the clinics during 6 time periods of 6 weeks each, with a transition period of no data collection during intervention implementation. The number of visits to be surveyed will vary by period and cluster. We plan to recruit patients and professionals for surveys during 405 visits. In the experimental periods, visits will be conducted with two partnership tools and associated clinic process changes: (1) a 1-page visit preparation guide given to relevant patients by clinic staff before seeing the provider, with the intention to improve communication and shared decision-making, and (2) a library of short educational videos that clinic staff encourage patients to watch on medication safety. In the control periods, visits will be conducted with usual care. The primary outcome will be patients' self-efficacy in medication use. The secondary outcomes are medication-related issues such as duplicate therapies identified by primary care providers and assessment of collaborative work during visits.

RESULTS

The study was funded in September 2019. Data collection started in April 2023 and ended in December 2023. Data was collected for 405 primary care encounters during that period. As of February 15, 2024, initial descriptive statistics were calculated. Full data analysis is expected to be completed and published in the summer of 2024.

CONCLUSIONS

This study will assess the impact of patient partnership tools and associated process changes in primary care on medication use self-efficacy and medication-related issues. The study is powered to identify types of patients who may benefit most from patient engagement tools in primary care visits.

Entangled in complexity: An ethnographic study of organizational adaptability and safe care transitions for patients with complex care needs

AIM

The aim of this study was to visualize vulnerabilities and explore the dynamics of inter-professional collaboration and organizational adaptability in the context of care transitions for patients with complex care needs.

DESIGN

An ethnographic design using multiple convergent data collection techniques.

METHODS

Data collection involved document review, participant observations and interviews with healthcare and social care professionals (HSCPs). Narrative analysis was employed to construct two illustrative patient scenarios, which were then examined using the Functional Resonance Analysis Method (FRAM). Thematic analysis was subsequently applied to synthesize the findings.

RESULTS

Inconsistencies in timing and precision during care transitions pose risks for patients with complex care needs as they force healthcare systems to prioritize structural constraints over individualized care, especially during unforeseen events outside regular hours. Such systemic inflexibility can compromise patient safety, increase the workload for HSCPs and strain resources. Organizational adaptability is crucial to managing the inherent variability of patient needs. Our proposed 'safe care transition pathway' addresses these issues, providing proactive strategies such as sharing knowledge and increasing patient participation, and strengthening the capacity of professionals to meet dynamic care needs, promoting safer care transitions.

CONCLUSION

To promote patient safety in care transitions, strategies must go beyond inter-professional collaboration, incorporating adaptability and flexible resource planning. The implementation of standardized safe care transition pathways, coupled with the active participation of patients and families, is crucial. These measures aim to create a resilient, person-centred approach that may effectively manage the complexities in care transitions.

IMPLICATIONS

The recommendations of this study span the spectrum from policy-level changes aimed at strategic resource allocation and fostering inter-professional collaboration to practical measures like effective communication, information technology integration, patient participation and family involvement. Together, the recommendations offer a holistic approach to enhance care transitions and, ultimately, patient outcomes.

Medication Management Strategies by Community-Dwelling Older Adults: A Multisite Qualitative Analysis

OBJECTIVES

Community-dwelling older adults taking 5 or more medications are at risk for medication-related harm. Managing multiple medications is a challenging task for patients and caregivers. Community-dwelling older adults self-manage their medications with minimal healthcare professional supervision. Although organizations, such as the Food and Drug Administration, often issue guidelines to ensure medication safety, how older adults understand and mitigate the risk of harm from medication use in the home environment is poorly understood.

METHODS

We conducted semistructured interviews with community-dwelling older adults 65 years and older who took 5 or more prescription medications to explore medication safety strategies they use. We also compared 2 organizations' medication safety guidelines for areas of concordance and discordance.

RESULTS

A total of 28 older adults were interviewed. Four overarching themes of medication management strategies emerged: collaborating with prescribers, collaborating with pharmacists, learning about medications, and safe practices at home. Study findings revealed that older adults followed some of the published guidelines by the 2 government organizations, although there were some areas of discord. Some of the strategies used were unintentionally against the recommended guidelines. For example, older adults tried weaning themselves off their medications without notifying their providers.

CONCLUSIONS

Older adults and their caregivers in our study used strategies different from those recommended by government organizations in managing medications to enhance drug safety. Patient-provider collaboration and positive patient outcomes can be improved by understanding and respecting strategies older adults use at home. Future studies must effectively incorporate older adults' perspectives when developing medication safety guidelines.

Primary care teams' reported actions to improve medication safety: a qualitative study with insights in high reliability organising

BACKGROUND

Our aim was to understand actions by primary care teams to improve medication safety.

METHODS

This was a qualitative study using one-on-one, semistructured interviews with the questions guided by concepts from collaborative care and systems engineering models, and with references to the care of older adults. We interviewed 21 primary care physicians and their team members at four primary care sites serving patients with mostly low socioeconomic status in Southwest US during 2019-2020. We used thematic analysis with a combination of inductive and deductive coding. First, codes capturing safety actions were incrementally developed and revised iteratively by a team of multidisciplinary analysts using the inductive approach. Themes that emerged from the coded safety actions taken by primary care professionals to improve medication safety were then mapped to key principles from the high reliability organisation framework using a deductive approach.

RESULTS

Primary care teams described their actions in medication safety mainly in making standard-of-care medical decisions, patient-shared decision-making, educating patients and their caregivers, providing asynchronous care separate from office visits and providing clinical infrastructure. Most of the actions required customisation at the individual level, such as limiting the supply of certain medications prescribed and simplifying medication regimens in certain patients. Primary care teams enacted high reliability organisation principles by anticipating and mitigating risks and taking actions to build resilience in patient work systems. The primary care teams' actions reflected their safety organising efforts as responses to many other agents in multiple settings that they could not control nor easily coordinate.

CONCLUSIONS

Primary care teams take many actions to shape medication safety outcomes in community settings, and these actions demonstrated that primary care teams are a reservoir of resilience for medication safety in the overall healthcare system. To improve medication safety, primary care work systems require different strategies than those often used in more self-contained systems such as hospital inpatient or surgical services.

Anticoagulation-Associated Adverse Drug Events in Hospitalized Patients Across Two Time Periods

PURPOSE

Anticoagulants often cause adverse drug events (ADEs), comprised of medication errors and adverse drug reactions, in patients. Our study objective was to determine the clinical characteristics, types, severity, cause, and outcomes of anticoagulation-associated ADEs from 2015-2020 (a contemporary period following implementation of an electronic health record, infusion device technology, and anticoagulant dosing nomograms) and to compare them with those of a historical period (2004-2009).

METHODS

We reviewed all anticoagulant-associated ADEs reported as part of our hospital-wide safety system. Reviewers classified type, severity, root cause, and outcomes for each ADE according to standard definitions. Reviewers also assessed events for patient harm. Patients were followed up to 30 days after the event.

RESULTS

Despite implementation of enhanced patient safety technology and procedure, ADEs increased in the contemporary period. In the contemporary period, we found 925 patients who had 984 anticoagulation-associated ADEs, including 811 isolated medication errors (82.4%); 13 isolated adverse drug reactions (1.4%); and 160 combined medication errors, adverse drug reactions, or both (16.2%). Unfractionated heparin was the most frequent ADE-related anticoagulant (77.7%, contemporary period vs 58.3%, historical period). The most frequent anticoagulation-associated medication error in the contemporary period was wrong rate or frequency of administration (26.1%, n = 253), with the most frequent root cause being prescribing errors (21.3%, n = 207). The type, root cause, and harm from ADEs were similar between periods.

CONCLUSIONS

We found that anticoagulation-associated ADEs occurred despite advances in patient safety technologies and practices. Events were common, suggesting marginal improvements in anticoagulant safety over time and ample opportunities for improvement.
