Evaluation of pharmacist‐led physician‐supported inpatient deprescribing model in older patients admitted to an acute general medical unit

Hospitalized Patients with Delirium and 28-Day Unplanned Hospital Readmissions: A Longitudinal Retrospective Cohort Study

OBJECTIVE

To establish the predictors of 28-day unplanned hospital readmissions (28D-UHR) in older adults (aged >65 years) with delirium during index hospital admission.

DESIGN

Retrospective longitudinal cohort study.

SETTING AND PARTICIPANTS

1634 patients (aged >65 years) admitted to a Melbourne quaternary hospital with delirium during index admission.

METHODS

Delirium during hospital admission was defined by the inclusion of one of the following International Classification of Diseases, Tenth Revision, codes F05.0, F05.1, F05.8, or F05.9 in the hospital medical discharge summary. Descriptive statistics were obtained for baseline characteristics. Multivariate logistic regression model was developed to assess predictors of 28D-UHR.

RESULTS

A total of 1634 patients with delirium during their inpatient admission were included, with 9.8% (160 patients) incidence of 28D-UHR. For patients who were readmitted, a shorter length of stay [odds ratio (OR) 0.98, 95% CI 0.96-0.99], higher number of medications on discharge from index admission (OR 1.10, 95% CI 1.06-1.14), and residing in a nursing home preadmission (OR 1.35, 95% CI 1.04-1.75) were associated with 28D-UHR.

CONCLUSIONS AND IMPLICATIONS

This study found that nursing home residence pre index admission, shorter length of stay (LOS), and polypharmacy were predictors of 28D-UHR. Further research into strategies to minimize 28D-UHR is required. Exploration of predischarge pharmacy-driven deprescribing programs and hospital-based postdischarge support for nursing home staff are important areas for future intervention.

Influence of Potentially Inappropriate Medication Use on Older Australians' Admission to Emergency Department Short Stay

Older people in the emergency department (ED) often pose complex medical challenges, with a significant prevalence of polypharmacy and potentially inappropriate medicines (PIMs) in Australia. A retrospective analysis of 200 consecutive patients aged over 65 years admitted to the emergency short stay unit (ESSU) aimed to identify polypharmacy (five or more regular medications), assess PIM prevalence, and explore the link between pre-admission PIMs and ESSU admissions. STOPP/START version 2 criteria were used for the PIM assessment, with an expert panel categorizing associated risks. Polypharmacy was observed in 161 patients (80.5%), who were older (mean age 82 versus 76 years) and took more regular medications (median 9 versus 3). One hundred and eighty-five (92.5%) patients had at least one PIM, 81 patients (40.5%) had STOPP PIMs, and 177 patients (88.5%) had START omissions. Polypharmacy significantly correlated with STOPP PIM (OR 4.8; 95%CI: 1.90-12.1), and for each additional medication the adjusted odds of having a STOPP PIM increased by 1.20 (95%CI: 1.11-1.28). Nineteen admissions (9.5%) were attributed to one or more PIMs (total 21 PIMs). Of these PIMs, the expert panel rated eight (38%) as high risk, five (24%) as moderate risk, and eight (38%) as low risk for causing hospital admission. The most common PIMs were benzodiazepines, accounting for 14 cases (73.6%). Older ESSU-admitted patients commonly presented with polypharmacy and PIMs, potentially contributing to their admission.

Polypharmacy in the Cardiovascular Geriatric Critical Care Population: Improving Outcomes

The cardiovascular geriatric population requiring intensive or critical care is a group vulnerable to adverse outcomes because of age, the critical care environment, geriatric syndromes, and multiple chronic conditions. Polypharmacy increases the risk of adverse events in this group. Several tools and aids are available to guide the clinical practice of appropriate prescribing and deprescribing. To optimize the care of the cardiovascular geriatric population, evidence-based prescribing, and deprescribing tools can be implemented by the interprofessional team consisting of the patient, their support system, critical care nurses, advanced practice clinicians, physicians, and allied health professionals.

Deprescribing medicines in older people living with multimorbidity and polypharmacy: the TAILOR evidence synthesis

BACKGROUND

Tackling problematic polypharmacy requires tailoring the use of medicines to individual needs and circumstances. This may involve stopping medicines (deprescribing) but patients and clinicians report uncertainty on how best to do this. The TAILOR medication synthesis sought to help understand how best to support deprescribing in older people living with multimorbidity and polypharmacy.

OBJECTIVES

We identified two research questions: (1) what evidence exists to support the safe, effective and acceptable stopping of medication in this patient group, and (2) how, for whom and in what contexts can safe and effective tailoring of clinical decisions related to medication use work to produce desired outcomes? We thus described three objectives: (1) to undertake a robust scoping review of the literature on stopping medicines in this group to describe what is being done, where and for what effect; (2) to undertake a realist synthesis review to construct a programme theory that describes 'best practice' and helps explain the heterogeneity of deprescribing approaches; and (3) to translate findings into resources to support tailored prescribing in clinical practice.

DATA SOURCES

Experienced information specialists conducted comprehensive searches in MEDLINE, Cumulative Index to Nursing and Allied Health Literature, Web of Science, EMBASE, The Cochrane Library (Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials), Joanna Briggs Institute Database of Systematic Reviews and Implementation Reports, Google (Google Inc., Mountain View, CA, USA) and Google Scholar (targeted searches).

REVIEW METHODS

The scoping review followed the five steps described by the Joanna Briggs Institute methodology for conducting a scoping review. The realist review followed the methodological and publication standards for realist reviews described by the Realist And Meta-narrative Evidence Syntheses: Evolving Standards (RAMESES) group. Patient and public involvement partners ensured that our analysis retained a patient-centred focus.

RESULTS

Our scoping review identified 9528 abstracts: 8847 were removed at screening and 662 were removed at full-text review. This left 20 studies (published between 2009 and 2020) that examined the effectiveness, safety and acceptability of deprescribing in adults (aged ≥ 50 years) with polypharmacy (five or more prescribed medications) and multimorbidity (two or more conditions). Our analysis revealed that deprescribing under research conditions mapped well to expert guidance on the steps needed for good clinical practice. Our findings offer evidence-informed support to clinicians regarding the safety, clinician acceptability and potential effectiveness of clinical decision-making that demonstrates a structured approach to deprescribing decisions. Our realist review identified 2602 studies with 119 included in the final analysis. The analysis outlined 34 context-mechanism-outcome configurations describing the knowledge work of tailored prescribing under eight headings related to organisational, health-care professional and patient factors, and interventions to improve deprescribing. We conclude that robust tailored deprescribing requires attention to providing an enabling infrastructure, access to data, tailored explanations and trust.

LIMITATIONS

Strict application of our definition of multimorbidity during the scoping review may have had an impact on the relevance of the review to clinical practice. The realist review was limited by the data (evidence) available.

CONCLUSIONS

Our combined reviews recognise deprescribing as a complex intervention and provide support for the safety of structured approaches to deprescribing, but also highlight the need to integrate patient-centred and contextual factors into best practice models.

FUTURE WORK

The TAILOR study has informed new funded research tackling deprescribing in sleep management, and professional education. Further research is being developed to implement tailored prescribing into routine primary care practice.

The process of deprescribing in older adults: a methodological protocol

Objective: To report, by means of a methodological protocol, the process of deprescribing implemented in a geriatric psychiatry outpatient clinic of a teaching hospital. Methods: The topic of interest was comprehensively reviewed in the scientific literature. Instruments and tools necessary to develop the protocol were selected, including the Treatment Adherence Measure, Beers criteria, the EURO-FORTA List, the Brazilian Consensus on Potentially Inappropriate Medications for Older Persons, Drugs.com, and deprescribing algorithms. Results: The protocol consists of the following steps: 1) Review: Assess older patients’ physical and behavioral status and family context and list all medications used; 2) Analyze: Review patients’ drug therapy; 3) Act: Initiate deprescribing (if indicated); 4) Adjust: Discuss patients’ expectations, beliefs, and preferences and adjust the prescription to their real possibilities; 5) Monitor: Identify responses to treatment, assess adherence to the deprescribing process, and detect return of symptoms or worsening of the underlying disease. Conclusions: Health care professionals need to work together to provide comprehensive care for older persons. The inclusion of deprescribing in more research groups focused on the geriatric population will increase attention to the safety of pharmacological treatment for older patients.

Evaluating the Impact of Education on Pharmacist Tobramycin Dose Recommendations for Cystic Fibrosis and a Review of Perceptions on Pharmacist-Led Charting

BACKGROUND

Pharmacists routinely interpret and optimize tobramycin dosing for people with cystic fibrosis (PwCF).

OBJECTIVES

To determine the impact of tobramycin therapeutic drug monitoring (TDM) education on pharmacist dose recommendations, and to explore nurses' and medical doctors' perceptions toward pharmacist-led TDM charting.

METHODS

This study involved 3 phases: a 12-month retrospective audit of PwCF prescribed tobramycin to identify the appropriateness of pharmacists' dose recommendations, a pharmacist tobramycin educational intervention utilizing a voiceover presentation with pre- and post-online tobramycin TDM assessment (involving multiple choice pharmacokinetics and case-based scenario questions), and a cross-sectional survey of respiratory nurses' and doctors' perceptions toward pharmacist-led TDM charting. The pharmacists' dose recommendations, in the audit and case-based questions, were considered appropriate if subsequent levels achieved the targeted area under the curve (AUC).

RESULTS

Audit results revealed that 44.4% of the 277 pharmacist dose recommendations identified were appropriate. The pre- and post-interventional assessments were completed by 51 and 52 pharmacists, respectively. Post intervention, correct scores were significantly higher than pre-intervention, evident in both the pharmacokinetics (median score 75% vs 100%; P = 0.048) and case-based scenario (median score 60% vs 90%; P < 0.0001) questions. Of the 54 nurses and medical doctors surveyed, 92.6% supported the implementation of pharmacist-led tobramycin charting.

CONCLUSION

The study demonstrated an increased accuracy and appropriateness of pharmacists' tobramycin pharmacokinetics knowledge and TDM dose recommendations post-educational intervention and highlighted nurses' and medical doctors' support of pharmacist-led tobramycin TDM charting.

Managing Polypharmacy in Older Adults with Cancer Across Different Healthcare Settings

The care of older patients with cancer is becoming increasingly complex. Common challenges for this population include management of comorbidities, safe transitions of care, and appropriate medication use. In particular, polypharmacy-generally defined as the regular use of five or more medications-and inappropriate medication use can lead to adverse effects and poor outcomes in older adults with cancer, including falls, hospital readmissions, cognitive impairment, poor adherence to essential medications, chemotherapy toxicity, and increased mortality. Managing polypharmacy across different cancer care settings is often challenging. Providers face barriers to safe and successful medication management that may include lack of time, absence of reimbursement, underappreciation of the scale of polypharmacy-related harm, lack of ownership of deprescribing efforts, and poor communication across care settings. Existing literature on managing inappropriate medication use and polypharmacy in older adults with cancer has often focused on ideal state settings in which resources are plentiful and time is purposefully allocated for medication interventions. This paper presents a narrative, rather than a systematic review, of studies published in the past decade that provided detailed information on medication management and polypharmacy across cancer care settings. This review aims to also summarize different healthcare provider roles in taking action against inappropriate medication use and polypharmacy in older adults with cancer.

Exploring Patients' Attitudes Toward Deprescribing and Their Perception of Pharmacist Involvement in a European Country: A Cross-Sectional Study

PURPOSE

To explore how adult patients perceive deprescribing in a country with developing pharmaceutical care.

PATIENTS AND METHODS

This was a multicenter cross-sectional study conducted in ten community pharmacies across Croatia. Community-dwelling adults 40 years and older, taking at least one prescription medication long term, were invited to participate. The revised and validated Patients' Attitude Towards Deprescribing Questionnaire was used to investigate community-dwelling adults' opinions on potential medication discontinuation. Questions regarding the patients' perception of pharmacist competences and involvement as well as patients' preferences in deprescribing were added. Collected data were analyzed using IBM SPSS Statistics using descriptive and inferential statistical analysis. Binary logistic regression was used to explore potential predictive factors of willingness to have medication deprescribed. All tests were performed as two-tailed and a p < 0.05 was considered statistically significant.

RESULTS

A total of 315 adults aged 40 years and older completed the questionnaire. Majority of participants, 83.81% (95% CI, 79.72% to 87.90%) stated that they were satisfied with their medications, and 83.81% (95% CI, 79.72% to 87.90%) would be willing to deprescribe one or more medications. Participants expressed a positive attitude toward pharmacists' competences (68.89%, 95% CI, 63.75% to 74.03%) and involvement in deprescribing (71.11%, 95% CI, 66.08% to 76.14%). Participants who stated specific medication as deprescribing preference were more likely show dissatisfaction with current medication and show greater willingness to have medication deprescribed. Three factors were found to be associated with a positive attitude towards deprescribing: low concerns about stopping factor score (aOR 0.54, 95% CU=0.35-0.84; p=0.006), low appropriateness factor score (aOR 0.62, 95% CI=0.39-0.98; p=0.039), and a positive opinion on pharmacist involvement (aOR 2.35, 95% CI=1.18-4.70; p= 0.016).

CONCLUSION

This study showed the patient's willingness for deprescription as well as their positive attitude towards pharmacists being involved in the process. Results favour transition to a patient-centred care and shared-decision making model.

Thoughtful Prescribing and Deprescribing

Polypharmacy, the use of five or more medications, is common in older adults. It can lead to the use of potentially inappropriate medications and severe adverse outcomes. Deprescribing is an essential step of the thoughtful prescribing process and it can decrease the use of potentially inappropriate medications. Studies have demonstrated that deprescribing is feasible in the clinical setting, especially when it incorporates patient preferences, shared decision making, and an interdisciplinary team. Medication-specific algorithms can facilitate deprescribing in the clinical setting.
