Improving dose-related adverse drug events among hospitalized older adults using a geriatric prescribing context

BACKGROUND

Adverse drug events (ADEs) during hospitalization are a serious, yet preventable concern for older adults. Our institution designed a Geriatric Prescribing Context (GPC) to adjust doses for the older adult population but its impact on ADEs was unknown. The goal of this study was to assess any differences in rates of ADEs before and after its implementation in July 2017.

METHODS

We used relevant ICD-10 codes followed by confirmatory chart review to identify dose-related ADEs from 10 commonly used medications at our institution. We assessed differences in the number of admissions with an ADE before and after the GPC implementation using a test of binomial proportions. The pre-period was from July 2016 through June 2017 and the post-period was from August 2017 through July 2018. We compared the rate of ADEs per 1000 patient days between periods with a Poisson rate test and further examined any differences in harm categories using a Fisher's exact test.

RESULTS

The proportion of admissions with any dose-related ADEs significantly decreased from 0.0082 to 0.0037 after the GPC (p = 0.04). The rate of dose-related ADEs also declined from 2.5 per 1000 patient days to 1.1 per 1000 patient days (p = 0.001). Harm categories did not change significantly between time points (p = 0.30).

CONCLUSIONS

Based on our list of relevant ICD-10 codes, the GPC was associated with lower dose-related ADEs for our selected medications among hospitalized older adults.

Is It Safe to Buy Medications from an App? Evaluation of Medication Prescribing Applications Available in Australia

Prescription request applications (apps) have changed the way consumers can obtain prescription-only medications. However, there is a lack of research surrounding such apps and their potential risks to consumers. We conducted an Australian study to (1) identify and characterise prescription request apps available in Australia and (2) assess whether prescription request apps in Australia adhere to guidelines for safe prescribing. Three online platforms (iOS App Store, Google Play store and Google search engine) were searched using 14 different search terms. Prescription request apps were identified based on pre-defined inclusion criteria. To determine whether the prescription request apps adhere to a safe prescribing framework, five medications were selected, and their corresponding consultation questionnaires were assessed against the Australian National Prescribing Service MedicineWise 12 core competencies for safe prescribing. A total of seven prescription request apps were identified. Assessment of the prescription request apps revealed that none of the apps provided prescribers with sufficient information to meet all the competencies required for safe prescribing; rather, they inconsistently adhered to the safe prescribing framework. Thus, consumers and healthcare professionals should consider the implications and safety concerns of obtaining medications via prescription request apps.

Long-term impact of a geriatric prescribing context

BACKGROUND

The medication-related death of a hospitalized older adult elucidated the inappropriateness of medication default doses in our electronic health record (EHR) for older adults. In response, we created and implemented the Geriatric Prescribing Context (GPC), an EHR-based set of age-specific dose and frequency defaults for patients 75 years and older, in July 2017. Inpatient medication orders aligned with GPC defaults and showed significant dose decreases at one year for nine of ten most commonly used medications. This follow-up investigation examined GPC alignment of dose and frequency over the 42-month time period after its implementation.

METHODS

Order data for the ten most commonly used medications at OHSU Hospital were collected retrospectively from July 2016 through December 2020. We used Statistical Process Control charts to assess the proportion of medication orders aligning with the GPC's recommendations. Signals of special cause were evaluated to identify time periods when shifts in process averages likely occurred and suspected shifts were assessed using binomial proportion tests. We used RStudio (RStudio, Inc., version 1.2.5001) and Microsoft Excel (2016) to perform statistical analyses and control charts, respectively.

RESULTS

The preimplementation phase of all medications displayed no special causes. After significant initial improvement in 2017, control charts revealed three different patterns of performance. Eight medications maintained the initial improvement with one medication displaying a second significant improvement at a later date. Two medications showed a subsequent decline in performance not statistically different from baseline. Overall, eight of the ten medications were prescribed at more age-friendly doses and frequencies compared to baseline after 42 months.

CONCLUSIONS

The GPC is an effective method to support safer prescribing for hospitalized older patients, but long-term impacts may be medication-specific. Further investigation is needed to ensure appropriate prescribing across drug classes and understand the GPC's impact on patient outcomes like adverse drug events.

Feasibility of Safe Opioid Prescribing in Outpatient Palliative Care: A Quality Improvement Project

BACKGROUND

No guidelines for safe opioid prescribing in palliative care exist, which contributes to limited monitoring of opioid misuse in palliative care.

MEASURES

Feasibility of a safe opioid prescribing standard operating protocol (SOP) was determined by assessing the percentage of patients in an outpatient cancer center who completed each component of a five-component SOP.

INTERVENTION

A five-component SOP included: risk stratification for misuse, consent form, prescription drug monitoring program review, urine drug testing, and Naloxone for high-risk individuals.

OUTCOMES

After one year, compliance rates on four of the of the five-component SOP were greater or equal to 93%. Naloxone co-prescription for high-risk patients never reached over 78%, largely due to clinical decision not to co-prescribe if transition to hospice was imminent.

CONCLUSIONS/LESSONS LEARNED

Safe opioid prescribing measures are feasible in outpatient palliative care and can facilitate identification of individuals at risk for opioid misuse and prompt early interventions for misuse.

The prescription opioid conundrum: 21st century solutions to a millennia-long problem

Health-care professionals are faced with a daunting task: balancing appropriate care for chronic pain with their responsibility to keep patients and others safe from treatment-related harm. Whereas opioids have historically been considered an effective tool in the analgesic armamentarium, the rise of opioid abuse has caused the pendulum to swing away from prescribing opioids to an emphasis on safety. This paradigm shift risks neglecting the very real consequences of untreated/undertreated pain. Using data from the medical literature, this review examines influences on the real and perceived benefit-to-risk ratio for opioids and provides clinicians with a practical approach to prescribing opioids that minimizes the risk for abuse/misuse. There is appreciable clinical trial and observational evidence of efficacy/effectiveness with opioids used for pain management over the short or long term when considered in the context of pharmacologic alternatives. Enhancing the relative safety and minimizing the risk for abuse/misuse may be achieved through proactive prescription practices that include careful patient selection, risk assessment, individualized and multimodal treatment plans with established goals, initiating opioid treatment cautiously with an exit plan in place, ongoing assessments of response to therapy, and routine patient monitoring. Additionally, prescribing opioids with a lower potential for abuse or misuse (e.g. abuse-deterrent formulations) may provide a benefit. Using a pragmatic approach to prescribing practices, we postulate that the balance between benefit and risk can be favorable for opioid therapy in select patients, even for long-term treatment of chronic pain.

The use of daily electronic prompts to help improve antimicrobial stewardship in a critical care unit

INTRODUCTION

Antimicrobial resistance (AMR) represents a growing threat to public health, with the potential to reverse many of the gains made in modern medicine. AMR is contributed to by both inappropriate choice of antibiotics and inappropriate antibiotic course durations.

OBJECTIVES

The objective of this audit was to determine if the introduction of antimicrobial prescribing electronic prompts in an electronic patient record had a positive impact on antimicrobial stewardship.

METHODS

The audit examined the proportion of antibiotic prescriptions within a critical care unit in which both a valid stop date and indication were recorded. The audit was repeated on two occasions: first, after an education programme, and second, after the introduction of an electronic prompt within the patients' electronic patient record.

RESULTS

Chi-square analyses indicated that significant improvements in both the recording of indications (χ²(4) = 39.69, P <0.0001) and stop-dates (χ²(4) = 42.10, P <0.0001) occurred across the three audits.

CONCLUSION

We conclude that the novel use of daily electronic prompts has a positive impact on antimicrobial stewardship.

Attention-deficit/hyperactivity disorder and substance abuse

Attention-deficit/hyperactivity disorder (ADHD) and substance use disorders are inextricably intertwined. Children with ADHD are more likely than peers to develop substance use disorders. Treatment with stimulants may reduce the risk of substance use disorders, but stimulants are a class of medication with significant abuse and diversion potential. The objectives of this clinical report were to present practical strategies for reducing the risk of substance use disorders in patients with ADHD and suggestions for safe stimulant prescribing.
