Emergency department-based medication review on outpatient health services utilization: interrupted time series

Enhancing healthcare access for an older population: The age-friendly emergency department

Healthcare systems face significant challenges in meeting the unique needs of older adults, particularly in the acute setting. Age-friendly healthcare is a comprehensive approach using the 4Ms framework-what matters, medications, mentation, and mobility-to ensure that healthcare settings are responsive to the needs of older patients. The Age-Friendly Emergency Department (AFED) is a crucial component of a holistic age-friendly health system. Our objective is to provide an overview of the AFED model, its core principles, and the benefits to older adults and healthcare clinicians. The AFED optimizes the delivery of emergency care by integrating age-specific considerations into various aspects of (1) ED physical infrastructure, (2) clinical care policies, and (3) care transitions. Physical infrastructure incorporates environmental modifications to enhance patient safety, including adequate lighting, nonslip flooring, and devices for sensory and ambulatory impairment. Clinical care policies address the physiological, cognitive, and psychosocial needs of older adults while preserving focus on emergency issues. Care transitions include communication and involving community partners and case management services. The AFED prioritizes collaboration between interdisciplinary team members (ED clinicians, geriatric specialists, nurses, physical/occupational therapists, and social workers). By adopting an age-friendly approach, EDs have the potential to improve patient-centered outcomes, reduce adverse events and hospitalizations, and enhance functional recovery. Moreover, healthcare clinicians benefit from the AFED model through increased satisfaction, multidisciplinary support, and enhanced training in geriatric care. Policymakers, healthcare administrators, and clinicians must collaborate to standardize guidelines, address barriers to AFEDs, and promote the adoption of age-friendly practices in the ED.

Drug-Related Problems in Elderly Patients Attended to by Emergency Services

The progressive aging and comorbidities of the population have led to an increase in the number of patients with polypharmacy attended to in the emergency department. Drug-related problems (DRPs) have become a major cause of admission to these units, as well as a high rate of short-term readmissions. Anticoagulants, antibiotics, antidiabetics, and opioids have been shown to be the most common drugs involved in this issue. Inappropriate polypharmacy has been pointed out as one of the major causes of these emergency visits. Different ways of conducting chronic medication reviews at discharge, primary care coordination, and phone contact with patients at discharge have been shown to reduce new hospitalizations and new emergency room visits due to DRPs, and they are key elements for improving the quality of care provided by emergency services.

Factors associated with recurrent emergency department visits among people living with dementia: A retrospective cohort study

BACKGROUND

Research on factors associated with recurrent emergency department (ED) visits and their implications for improving dementia care is lacking. The objective of this study was to examine associations between the individual characteristics of older adults living with dementia and recurrent ED visits.

METHODS

We used health administrative databases to conduct a population-based retrospective cohort study among older adults with dementia in Ontario, Canada. We included community-dwelling adults 66 years and older who visited the ED between April 1, 2010, and March 31, 2019 and were discharged home. We recorded all ED visits within one year after the baseline visit. We used recurrent event Cox regression to examine associations between repeat ED visits and individual clinical, demographic, and health service use characteristics. We fit conditional inference trees to identify the most important factors and define subgroups of varying risk.

RESULTS

Our cohort included 175,863 older adults with dementia. ED use in the year prior to baseline had the strongest association with recurrent visits (3+ vs.0 adjusted hazard ratio (aHR): 1.92 (1.89, 1.94), 2vs.0 aHR: 1.45 (1.43, 1.47), 1vs.0 aHR: 1.23 (1.21, 1.24)). The conditional inference tree utilized history of ED visits and comorbidity count to define 12 subgroups with ED revisit rates ranging from 0.79 to 7.27 per year. Older adults in higher risk groups were more likely to live in rural and low-income areas and had higher use of anticonvulsants, antipsychotics, and benzodiazepines.

CONCLUSIONS

History of ED visits may be a useful measure to identify older adults with dementia who would benefit from additional interventions and supports. A substantial proportion of older adults with dementia have a pattern of recurrent visits and may benefit from dementia-friendly and geriatric-focused EDs. Collaborative medication review in the ED and closer follow-up and engagement with community supports could improve patient care and experience.

Clin-STAR corner: Practice changing advances in prescribing for geriatric emergency department patients

Reducing adverse drug events among older adults in heterogeneous and often chaotic emergency department (ED) settings requires a multidisciplinary approach. Recent research evaluates the impact of multicomponent protocols designed to reduce ED physician prescribing of potentially inappropriate medications (PIMs), including transdisciplinary training and leveraging electronic health records to provide real-time alternative safer pharmaceuticals while providing personalized feedback to prescribers. Most new research is not randomized trial data. Although this current research does not consistently demonstrate a reduction in the prescribing of PIMs, these studies provide a foundation for emergency medicine healthcare teams, geriatricians, and pharmacists to collaborate with health informatics to continue advancing the frontiers of safer medication prescribing during episodes of acute care.

Assessment of drug-related problems at the emergency department in older patients living with frailty: pharmacist-led medication reviews within a geriatric care team

BACKGROUND

Older patients are vulnerable to experiencing drug related problems (DRPs), which may result in emergency department (ED) visits. However, it is not standard practice to conduct medications reviews during ED visit. The aim of this study was to assess the number of DRPs in older patients living with frailty at the ED, identified through pharmacist-led medication reviews within a geriatric care team, and to determine the acceptance rate of pharmacists' recommendations among hospital physicians and general practitioners or elderly care specialists.

METHODS

A retrospective observational study was performed in patients ≥ 70 years living with frailty at the ED at Tergooi Medical Center. Pharmacist-led medication reviews were conducted to identify and classify DRPs as part of a larger geriatric assessment. The acceptance rate of given recommendations was determined during follow-up.

RESULTS

A total of 356 ED visits were included. The mean (standard deviation, SD) age of patients was 83 (6.8) years. About 76% of patients had at least one DRP. In total, 548 DRPs were identified with a mean of 1.5 DRP (SD 1.3) per patient. The acceptance rate of medication recommendations in admitted patients was 55%, and 32% among general practitioners/elderly care specialists in discharged patients.

CONCLUSIONS

Pharmacist-led medication reviews as part of a geriatric care team identified DRPs in 76% of older patients living with frailty at the ED. The acceptance rate was substantially higher in admitted patients compared to discharged patients.

The effect of emergency department pharmacists on drug overuse and drug underuse in patients with an ADE-related hospitalisation: a controlled intervention study

Background

Drug overuse or drug underuse are the most common causes of adverse drug events and can lead to hospital admissions. Using clinical pharmacists in the emergency department may improve patient safety as they are specialised in recognising of adverse drug events and tackling drug overuse and drug underuse. This study tested the effect of an emergency department pharmacist on the number of medication changes for drug overuse and drug underuse taking place in patients with an adverse drug event-related hospitalisation following an emergency department visit.

Methods

A multicenter prospective non-randomized controlled intervention study was conducted in a university hospital and a general teaching hospital. Trained emergency department pharmacists included patients in the intervention group with a hospital admission related to an adverse drug event. The interdisciplinary intervention consisted of a pharmacist-led medication review, patient counselling regarding medication, and information transmission to general practitioners and community pharmacies after discharge. The control patients were also admitted after an emergency department visit and received the usual care. The primary outcome was the number of medication changes for drug overuse and drug underuse that took place during hospital admission and persisted 6 months thereafter. Poisson regression analysis was used to estimate the difference in these medication changes between the intervention group and the control group.

Results

A total of 216 patients were included (intervention group 104, control group 112). In the intervention group, 156 medication changes for drug overuse and drug underuse persisted 6 months after admission compared to 59 in the control group (adjusted rate ratio 1.22 [95%CI 1.01-1.49] p = 0.039).

Conclusion

Emergency department pharmacists do contribute to reduction of drug overuse and drug underuse of medication in patients with a hospitalisation related to adverse drug events after an emergency department visit.

Impact of systematic medication review in emergency department on patients’ post-discharge outcomes—A randomized controlled clinical trial

Introduction

The main objective of this study was to investigate whether systematic medication review conducted by clinical pharmacists can impact clinical outcomes and post-discharge outcomes for patients admitted to the emergency department.

Method

This parallel group, non-blinded, randomized controlled trial was conducted in the emergency department, Diakonhjemmet Hospital, Oslo, Norway. The study was registered in ClinicalTrials.gov, Identifier: NCT03123640 in April 2017. From April 2017 to May 2018, patients ≥18 years were included and randomized (1:1) to intervention- or control group. The control group received standard care from emergency department physicians and nurses. In addition to standard care, the intervention group received systematic medication review including medication reconciliation conducted by pharmacists, during the emergency department stay. The primary outcome was proportion of patients with an unplanned contact with hospital within 12 months from inclusion stay discharge.

Results

In total, 807 patients were included and randomized, 1:1, to intervention or control group. After excluding 8 patients dying during hospital stay and 10 patients lacking Norwegian personal identification number, the primary analysis comprised 789 patients: 394 intervention group patients and 395 control group patients. Regarding the primary outcome, there was no significant difference in proportion of patients with an unplanned contact with hospital within 12 months after inclusion stay discharge between groups (51.0% of intervention group patients vs. 53.2% of control group patients, p = 0.546).

Conclusion

As currently designed, emergency department pharmacist-led medication review did not significantly influence clinical- or post-discharge outcomes. This study did, however pinpoint important practical implementations, which can be used to design tailored pharmacist-led interventions and workflow regarding drug-related issues in the emergency department setting.

Potentially Harmful Medication Dispenses After a Fall or Hip Fracture: A Mixed Methods Study of a Commonly Used Quality Measure

BACKGROUND

High-risk medication dispenses to patients with a prior fall or hip fracture represent a potentially dangerous disease-drug interaction among older adults. The research team quantified the prevalence, identified risk factors, and generated patient and provider insights into high-risk medication dispenses in a large, community-based integrated health system using a commonly used quality measure.

METHODS

This was a mixed methods study with a convergent design combining a retrospective cohort study using electronic health record (EHR) data, individual interviews of primary care physicians, and a focus group of patient advisors.

RESULTS

Of 113,809 patients ≥ 65 years with a fall/fracture in 2009-2015, 35.4% had a potentially harmful medication dispensed after their fall/fracture. Most medications were prescribed by primary care providers. Older age, male gender, and race/ethnicity other than non-Hispanic White were associated with a reduced risk of high-risk medication dispenses. Patients with a pre-fall/fracture medication dispense were substantially more likely to have a post-fall/fracture medication dispense (hazard ratio [HR] = 13.26, 95% confidence interval [CI] = 12.91-13.61). Both patients and providers noted that providers may be unaware of patient falls due to inconsistent assessments and patient reluctance to disclose falls. Providers also noted the lack of a standard location to document falls and limited decision support alerts within the EHR.

CONCLUSION

High-risk medication dispenses are common among older patients with a history of falls/fractures. Future interventions should explore improved assessment and documentation of falls, decision support, clinician training strategies, patient educational resources, building trusting patient-clinician relationships to facilitate long-term medication discontinuation among persistent medication users, and a focus on fall prevention.

The impact of introducing multidisciplinary care assessments on access to rheumatology care in British Columbia: an interrupted time series analysis

Background

In 2011 the British Columbia (BC) Ministry of Health introduced a new fee-for-service billing code that allowed “Multidisciplinary Care Assessment” (MCA). This change has the potential to change access to and quality of care for patients. This study aimed to explore the impact on access to rheumatology services in the province.

Methods

Fee-for-service rheumatology billings were evaluated for each rheumatologist 2 years before and after use of the MCA code. Numbers of 1) unique patients and 2) services provided per month were used as proxy measures of access to care. A multiple-baseline interrupted time series model assessed the impact of the MCA on levels and trends of the access outcomes.

Results

Our analysis consisted of 82,360 patients cared for by 26 rheumatologists who billed for an MCA. In our primary analysis we observed a sustained increase in the mean number of unique patients of 4.9% (95% CI: 0.0% to 9.9%, p = 0.049) and the mean number of services of 7.1% (95% CI: 1.0% to 13.6%, (p = 0.021), per month provided by a rheumatologist, corresponding to the initial use of MCA.

Conclusion

The introduction of the MCA code was associated with an initial increase in the measures of access, which was maintained but did not increase over time. Our study suggests that the use of Multidisciplinary Care Assessment can contribute to expanding and/or sustaining access to care for people with complex chronic conditions, like rheumatic diseases.

Collaborative Medication Reviews to Identify Inappropriate Prescribing in Pre-Admission Medications at Emergency Department Short-Term Ward

PURPOSE

Collaborative medication reviews (CMR) have been shown to reduce inappropriate prescribing (IP) in various settings. This study aimed at describing a CMR practice in an emergency department (ED) short-term ward in Finland to investigate IP in pre-admission medications.

PATIENTS AND METHODS

Pre-admission medications were collaboratively reviewed for all the adult ED admissions within a 5-month study period in 2016. Types of IP were inductively categorized, and descriptive statistics were used to show the incidence and type of IP events.

RESULTS

The pre-admission medications of 855 adult ED patients were reviewed by the pharmacist, with 113 IP events identified in 83 (9.7%) of the patients. The majority (81%, n=67) of these patients were older adults (≥65 years). Of these 94 IP events identified in 67 older patients, 58 (62%) were confirmed by the ED physicians. The following 3 main categories were inductively developed for the types of identified and confirmed IP events: 1) Misprescribing (prescription of medications that significantly increase the risk of adverse drug events); 2) Overprescribing (prescription of medications for which no clear clinical indications exist); and 3) Underprescribing (omission of potentially beneficial medications that are clinically indicated for treatment or prevention of a disease). Misprescribing was the most common type of IP identified (79% of the identified and 72% confirmed IP events). Benzodiazepines (29%) and antidepressants (28%) were involved in 33 out of 58 (57%) confirmed IP events. Medications with strong anticholinergic effects were involved in 19% of the confirmed IP events.

CONCLUSION

The CMR practice was able to identify IP in pre-admission medications of about one-tenth of ED patients. Older patients using benzodiazepines and drugs with strong anticholinergic effects should be paid special attention to ED admissions.
