Changes in medication profile among patients with advanced cancer admitted to an acute palliative care unit

Impact of Dosing and Duration of Dexamethasone on Serious Corticosteroid-Related Adverse Events

CONTEXT

Corticosteroids are commonly prescribed in oncology, but few studies have examined its adverse events (AEs) compared to placebo control.

OBJECTIVES

Using data from a double-blind, placebo-controlled randomized trial, we evaluated the association between the dose and duration of dexamethasone and serious AEs.

METHODS

This is a pre-planned secondary analysis of the Alleviating Breathlessness in Cancer Patients with Dexamethasone (ABCD) trial in which patients were randomized to dexamethasone 8 mg BID x1 week, then 4 mg BID x1 week or placebo, followed by an optional open-label phase with 4 mg BID x1 week, then 2 mg BID x1 week. The primary outcome was Grade 3+ AEs (CTCAE v4.03). We evaluated the association between AEs and dexamethasone exposure using multivariable logistic regression.

RESULTS

Among 119 cancer patients, 32 received intervention followed by open label (mean exposure 243 mg over 27 days), 47 received intervention with no open label, 20 received placebo followed by open label, and 20 received no dexamethasone. The most common AEs included insomnia (31%), dyspepsia (21%), neuropsychiatric symptoms (18%), and infections (17%). Overall, 38 (32%) had Grade 3+ AEs and 27 (23%) were hospitalized. Patients with the greatest exposure to dexamethasone experienced more Grade 3+ AEs compared to those with no exposure (65% vs. 15%); odds ratio of 15.1 (95% CI 1.4-160.8, P = 0.01).

CONCLUSION

Greater dexamethasone exposure, even at moderate doses, was associated with more serious AEs. Prescribers should cautiously weigh the risks and benefits of dexamethasone use, especially when considering for palliation of symptoms.

Prescribing practices, patterns, and potential harms in patients receiving palliative care: A systematic scoping review

Background

Patients receiving palliative care often have existing comorbidities necessitating the prescribing of multiple medications. To maximize quality of life in this patient cohort, it is important to tailor prescribing of medication for preventing and treating existing illnesses and those for controlling symptoms, such as pain, according to individual specific needs.

Objectives

To provide an overview of peer-reviewed observational research on prescribing practices, patterns, and potential harms in patients receiving palliative care.

Methods

A systematic scoping review was conducted using four electronic databases (PubMed, EMBASE, CINAHL, Web of Science). Each database was searched from inception to May 2020. Search terms included 'palliative care,' 'end of life,' and 'prescribing.' Eligible studies had to examine prescribing for adults (≥18 years) receiving palliative care in any setting as a study aim or outcome. Studies focusing on single medication types (e.g., opioids), medication classes (e.g., chemotherapy), or clinical indications (e.g., pain) were excluded. The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for scoping reviews, and the findings were described using narrative synthesis.

Results

Following deduplication, 16,565 unique citations were reviewed, and 56 studies met inclusion criteria. The average number of prescribed medications per patient ranged from 3 to 23. Typically, prescribing changes involved decreases in preventative medications and increases in symptom-specific medications closer to the time of death. Twenty-one studies assessed the appropriateness of prescribing using various tools. The prevalence of patients with ≥1 potentially inappropriate prescription ranged from 15 to 92%. Three studies reported on adverse drug events.

Conclusions

This scoping review provides a broad overview of existing research and shows that many patients receiving palliative care receive multiple medications closer to the time of death. Future research should focus in greater detail on prescribing appropriateness using tools specifically developed to guide prescribing in palliative care and the potential for harm.

Missed opportunities: unnecessary medicine use in patients with lung cancer at the end of life - an international cohort study

AIMS

The aims of the current study were: (i) to examine the prescribing of preventative medication in a cohort of people with advanced lung cancer on hospital admission and discharge across different healthcare systems; and (ii) to explore the factors that influence preventative medication prescribing at hospital discharge.

METHODS

A retrospective cohort study was conducted across two centres in the UK and the US. The prescribing of preventative medication was examined at hospital admission and discharge for patients who died of lung cancer. A zero-inflated negative binomial regression model was used to examine the association between preventative medications at discharge and patient- and hospital-based factors. The classes of preventative medication prescribed included were: vitamins and minerals, and antidiabetic, antihypertensive, antihyperlipidaemic and antiplatelet medications.

RESULTS

In the UK site (n = 125), the mean number of preventative medications prescribed was 1.9 [standard deviation (SD) 1.7) on admission, and 1.7 (SD 1.7) on discharge, and in the US site (n = 191) the mean was 2.6 (SD 2.2) on admission and 1.9 (SD 2.2) on discharge. The model found a significant association between the number of preventative drugs prescribed on admission and the number on discharge; it also found a significant association between the total number of drugs prescribed on discharge and the number of preventative medications on discharge. Other indicators related to patient and hospital factors were not significantly associated with the number of preventative medications supplied on discharge.

CONCLUSIONS

The use of preventative medication was common in lung cancer patients, despite undergoing discharge. Patient- and hospital-based factors did not influence the prescribing of preventative medication.

Palliative Care and Interventional Pulmonology

Since pulmonary pathologies, such as lung cancer and chronic obstructive pulmonary disease (COPD), are some of the leading causes of morbidity and mortality around the world, pulmonologists are likely to encounter patients with unmet palliative care needs. This article focuses on the symptoms and complications encountered by patients with terminal pulmonary conditions, briefly describes the non-interventional palliative strategies, and then discusses more advanced therapies available in the realm of interventional pulmonology. Most of the literature discussed here is derived from patients with lung cancer and COPD.

The Use of Corticosteroids as Adjuvant Therapy for Painful Bone Metastases: A Large Cross-Sectional Survey of Palliative Care Providers

Context:

Bone metastases are a common complication in patients with advanced cancer but little is known regarding current practice patterns of palliative care providers when prescribing corticosteroids as adjuvant therapy for painful bone metastases.

Objective:

To identify current practice patterns among palliative care providers when prescribing corticosteroids for the treatment of painful bone metastases.

Methods:

A cross-sectional, online survey of the membership of the American Academy of Hospice and Palliative Medicine. Providers were asked to report how frequently they prescribed corticosteroids as adjuvant therapy in patients with painful bone metastases, and to specify the corticosteroid, dosage, treatment duration, and the gastroprotective strategy most frequently utilized.

Results:

Seven hundred sixty-five participants responded to the survey and 600 (78%) of respondents completed the survey. Ninety-eight percent of respondents completing the survey reported having prescribed corticosteroids as adjuvant pain therapy, and 66% ordered corticosteroids for the majority of their patients with painful bone metastases. Dexamethasone was the most widely prescribed corticosteroid. Eight milligrams divided twice daily was the most common dosage selected and once started, it was usually continued indefinitely.

Conclusion:

Corticosteroids are commonly prescribed as adjuvant therapy in the treatment of painful bone metastases in patients with limited life expectancy. Dexamethasone is the most commonly selected corticosteroid by American palliative care providers with variation existing among providers regarding dosing schedule, treatment duration, and gastroprotective strategies. Clinical trials comparing a total daily dose of four versus eight milligrams of dexamethasone would be clinically useful to inform evidence-based practice.

Prescription and Deprescription of Medication During the Last 48 Hours of Life: Multicenter Study in 23 Acute Geriatric Wards in Flanders, Belgium

CONTEXT

Palliative care for the older person is often limited, resulting in poor quality of dying. Pharmacological management can be one of the components to achieve better symptom control.

OBJECTIVES

To describe the anticipatory prescription of medication for symptomatic treatment and the deprescription of potentially inappropriate medication during the last days of life.

METHODS

This was a cross-sectional descriptive study between October 1, 2012 and September 30, 2013 in 23 acute geriatric wards in Flanders, Belgium. Structured after-death questionnaires were filled out by the treating geriatrician for patients hospitalized for more than 48 hours before dying.

RESULTS

Anticipatory prescription of medication was present in 65.4% of cases, 45.5% of the cases was prescribed morphine, 15.5% benzodiazepines, and 13.8% scopolamine hydrobromide. A deprescription of potentially inappropriate medication was noted in 67.9% of cases. The likelihood of anticipatory prescription was significantly higher in cases where death was expected (odds ratio [OR] 19; 95% CI 9-40; P < 0.0001) and significantly lower where dementia was present (OR 0.35; 95% CI 0.16-0.74; P < 0.006). The likelihood of deprescription was higher in cases where death was expected (OR 20; 95% CI 10-43; P < 0.0001) and in cases of patients dying from an oncological disease compared with those dying from frailty or dementia (OR 7.0; 95% CI 1.1-45.6, P = 0.042).

CONCLUSION

Anticipatory prescription of medication and deprescription of medication at the end of life in acute geriatric wards could be further optimized. A well-developed intervention to guide health care staff in patient-centered pharmacological management in the last days of life seems to be needed.
