Evaluation of Prescribing Medications for Terminal Cancer Patients near Death: Essential or Futile

Impact of palliative care at end-of-life Covid-19 patients - a small-scale pioneering experience

BACKGROUND

In March 2020, the outbreak caused by the SARS-CoV-2 virus was declared a pandemic, resulting in numerous fatalities worldwide. To effectively combat the virus, it would be beneficial to involve professionals who specialize in symptom control for advanced illnesses, working closely with other specialties throughout the illness process. This approach can help manage a range of symptoms, from mild to severe and potentially life-threatening. No studies have been conducted in Portugal to analyse the intervention of Palliative Medicine at the end of life of Covid-19 patients and how it differs from other specialties. This knowledge could help determine the importance of including it in the care of people with advanced Covid-19.

OBJECTIVES

The objective of this study is to examine potential differences in the care provided to patients with Covid-19 during their Last Hours and Days of Life (LHDOL) between those who received care from Palliative Medicine doctors and those who did not.

METHODS

This is a retrospective cohort study spanning three months (Dec 2020 to Feb 2021), the duration of the Support Unit especially created to deal with Covid-19 patients. The database included clinical files from 181 patients admitted to the Support Unit, 27 of which died from Covid-19.

RESULTS

Statistically significant differences were identified in the care provided. Specifically, fewer drugs were administered at the time of death, including drugs for dyspnoea, pain and agitation, suspension of futile devices and use of palliative sedation to control refractory symptoms.

CONCLUSIONS

End-of-life care and symptomatic control differ when there's regular follow-up by Palliative Medicine, which may translate less symptomatic suffering and promote a dignified and humane end of life.

Examining Final-Administered Medication as a Measure of Data Quality: A Comparative Analysis of Death Data with the Central Cancer Registry in Republic of Korea

Death is a crucial outcome in retrospective cohort studies, serving as a criterion for analyzing mortality in a database. This study aimed to assess the quality of extracted death data and investigate the potential of the final-administered medication as a variable to quantify accuracy for the validation dataset. Electronic health records from both an in-hospital and the Korean Central Cancer Registry were used for this study. The gold standard was established by examining the differences between the dates of in-hospital deaths and cancer-registered deaths. Cosine similarity was employed to quantify the final-administered medication similarities between the gold standard and other cohorts. The gold standard was determined as patients who died in the hospital after 2006 and whose final hospital visit/discharge date and death date differed by 0 or 1 day. For all three criteria-(a) cancer stage, (b) cancer type, and (c) type of final visit-there was a positive correlation between mortality rates and the similarities of the final-administered medication. This study introduces a measure that can provide additional accurate information regarding death and differentiates the reliability of the dataset.

Treatment patterns and out-of-hospital healthcare resource utilisation by patients with advanced cancer living with pain: An analysis from the Stop Cancer PAIN trial

BACKGROUND

About 70% of patients with advanced cancer experience pain. Few studies have investigated the use of healthcare in this population and the relationship between pain intensity and costs.

METHODS

Adults with advanced cancer and scored worst pain ≥ 2/10 on a numeric rating scale (NRS) were recruited from 6 Australian oncology/palliative care outpatient services to the Stop Cancer PAIN trial (08/15-06/19). Out-of-hospital, publicly funded services, prescriptions and costs were estimated for the three months before pain screening. Descriptive statistics summarize the clinico-demographic variables, health services and costs, treatments and pain scores. Relationships with costs were explored using Spearman correlations, Mann-Whitney U and Kruskal-Wallis tests, and a gamma log-link generalized linear model.

RESULTS

Overall, 212 participants had median worst pain scores of five (inter-quartile range 4). The most frequently prescribed medications were opioids (60.1%) and peptic ulcer/gastro-oesophageal reflux disease (GORD) drugs (51.6%). The total average healthcare cost in the three months before the census date was A$6,742 (95% CI $5,637, $7,847), approximately $27,000 annually. Men had higher mean healthcare costs than women, adjusting for age, cancer type and pain levels (men $7,872, women $4,493, p<0.01) and higher expenditure on prescriptions (men $5,559, women $2,034, p<0.01).

CONCLUSIONS

In this population with pain and cancer, there was no clear relationship between healthcare costs and pain severity. These treatment patterns requiring further exploration including the prevalence of peptic ulcer/GORD drugs, and lipid lowering agents and the higher healthcare costs for men.

Prescription trends at the end of life in a palliative care unit: observational study

Background

Symptomatic control is essential in palliative care, particularly in end-of-life, in which the pathophysiological changes that characterize this last phase of life strengthen the need to carry out an early therapeutic review. Hence, we aim to evaluate the prescribing pattern at a palliative care unit at two different time points: on admission and the day of the patient’s death.

Methods

Quantitative, analytic, longitudinal, retrospective and observational study. Participants were adult patients who were admitted and died in a palliative care unit, in Portugal. Sociodemographic, clinical and pharmacological data were collected, including frequencies and routes of administration of schedule prescribed drugs and rescue drugs, from the day of admission until the day of death.

Results

115 patients were included with an average age of 70.0 ± 12.9 years old, 53.9 were male, mostly referred by the Hospital Palliative Care Support Teams. The most common pathology was cancer, mainly in advanced stage. On admission, the median scheduled prescription was seven and “as needed” was three drugs. On the day of death, a decrease of prescriptions was observed. Opioids were always the most prescribed drugs. Near death, there was a higher tendency to prescribe butylscopolamine, midazolam, diazepam and levomepromazine. The most frequent route of drug administration was oral on admission and subcutaneous on the day of death.

Conclusions

Polypharmacy is a reality in palliative care despite specialist palliative care teams. A reduction of prescribed drugs was verified, essentially due less comorbidity-oriented drugs. Further studies are required to analyse the importance of Hospital Palliative Care Support Teams.

Use of potentially inappropriate medication in older patients with lung cancer at the end of life

OBJECTIVES

Medications at the end of life should be used for symptom control. Medications which potential adverse effects outweigh their expected benefits are called 'potentially inappropriate medications' (PIMs). PIMs are related with adverse drug events and reduced quality of life. In this study, we investigated to what extent PIMs are dispensed to older patients with lung cancer in the last month of life.

METHODS

We selected patients with lung cancer, aged 65+, diagnosed between 2009 and 2014, and who died before April 1st 2015 from the population-based Netherlands Cancer Registry (NCR). The NCR is linked to the PHARMO Database Network, that includes medications dispensed by community pharmacies in the Netherlands. The eight PIM groups were based on the OncPal Deprescribing Guideline: aspirin, dyslipidaemia medications, antihypertensives, osteoporosis medications, peptic ulcer prophylaxis, oral hypoglycaemics, vitamins and minerals.

RESULTS

Data of 7864 patients with lung cancer were analyzed. Median age was 74 year (IQR = 70-79) and 67% was male. 45% of all patients received at least one PIM in their last month of life. Taking into account all dispensed medications, patients receiving PIMs received more different medications compared to those receiving no PIMs, respectively 10 (SD = 5) vs. 3 (SD = 4) different medications (P < 0.001).

CONCLUSION

Almost half of the older patients with lung cancer in the Netherlands received PIMs in their last month of life. Since PIM use is associated with reduced quality of life, it is important that health care professionals continue to critically assess which medication can be discontinued at the end of life.

Prescription and deprescription of medications for older adults receiving palliative care during the last 3 months of life: a single-center retrospective cohort study

PURPOSE

Near the end of life, drugs to ensure comfort and improve quality of life should be prioritized, and unnecessary drugs should be avoided. The aim was to assess the evolution and quality of drug therapy throughout the last 3 months of life of older adults in need of palliative care.

METHODS

A single-center retrospective cohort study included older adults (≥ 65 years) who died in a teaching hospital between 1 January 2014 and 30 June 2014 and had been identified as patients in need of palliative care in their last 3 months of life. Drugs were collected from electronic medical records and defined as 'unnecessary' or 'essential' based on a review of the literature.

RESULTS

A total of 149 patients were included [age: 82.1 (SD 8.6) years, women: 46.3%]. The mean number of medications varied from 6.7 (SD 3.3) drugs 90 days before death, to 7.5 (SD 4.1) 7 days before death, to 5.6 (SD 3.6) on the day of death. During the final week of life, one additional prescription of essential drugs was observed for 75.2% of patients and 79.3% of patients had at least one unnecessary drug deprescribed. The most prescribed and deprescribed drug classes were, respectively, analgesics (56.4%) and antithrombotic agents (38.2%) during the last week of life.

CONCLUSIONS

Near the end of life, medication therapy is adapted to the goals of palliative care. However, this only occurs during the last week of life. Earlier transition to palliative care is necessary to avoid exposure to unnecessary drugs.

The Use of Antidiabetic, Antihypertensive, and Lipid-lowering Medications in the Elderly Dying with Advanced Cancer

Background

Maintenance of medications that are unconducive to the quality of life is difficult to justify in dying terminally-ill cancer patients.

Objective

We aimed at determining the prevalence of administering antidiabetic, antihypertensive, and lipid-lowering medications to elderly patients dying with cancer.

Methods

We reviewed the medical records of patients above 60 years of age with advanced cancer who died in a palliative care unit. The collected data included the use of antidiabetic, antihypertensive, and lipid-lowering medications during the last week of life.

Results

Of 103 patients, 51.5% were female and the median age was 69 years. The most common cancers included gastrointestinal (40.8%), gynecological (13.6%), and head and neck (12.6%). All patients had advanced cancer and 59.2% had hypertension, 52.4% had diabetes mellitus, and 19.4% had dyslipidemia. During their last week of life, 38.8% received antidiabetic, 23.3% received antihypertensive, and 3.9% received lipid-lowering agents. The data showed that 68.5% of people with diabetes received antidiabetic medications, 37.7% of hypertensive patients received antihypertensive medications, and 20% of dyslipidemics received lipid-lowering agents. Hypoglycemia was reported in 7.5% of patients receiving antidiabetic drugs, while hypotension was reported in 66.7% of patients receiving antihypertensive agents.

Conclusion

Many elderly patients dying with advanced cancer in a palliative care unit were maintained on medications for chronic conditions until the very late stages of their lives. For such imminently dying patients, benefits of such medications are unlikely and burdens are possible. Further research is needed to explore physicians' justifications, if any, for maintaining such patients on apparently futile medications.

Deprescription in Advanced Cancer Patients

The use of multiple drugs is often referred to as polypharmacy, although this term has not been precisely defined. Frequently, drugs are used unwisely in multiple combinations increasing the risk of adverse reactions, or for the long-term prevention of diseases in patients with a short life expectancy who, therefore, will not benefit from them. The reflection on this has led to the introduction of the concept of deprescription. There are many reasons for the inappropriate drug prescription and barriers to reduce medications. Tools were developed to help prescribers to limit the number of prescribed drugs that patients are taking. Several studies have shown that deprescription of some drugs is possible and safe and can even have a positive influence on wellbeing, cognitive function, falls, and admission to a hospital. Deprescription should be individualized and carried out, as far as possible, in agreement with patients and their families. A six-step method for deprescription is proposed.

Non-beneficial treatments in hospital at the end of life: a systematic review on extent of the problem

PURPOSE

To investigate the extent of objective 'non-beneficial treatments (NBTs)' (too much) anytime in the last 6 months of life in routine hospital care.

DATA SOURCES

English language publications in Medline, EMBASE, PubMed, Cochrane library, and the grey literature (January 1995-April 2015).

STUDY SELECTION

All study types assessing objective dimensions of non-beneficial medical or surgical diagnostic, therapeutic or non-palliative procedures administered to older adults at the end of life (EOL).

DATA EXTRACTION

A 13-item quality score estimated independently by two authors.

RESULTS OF DATA SYNTHESIS

Evidence from 38 studies indicates that on average 33-38% of patients near the EOL received NBTs. Mean prevalence of resuscitation attempts for advanced stage patients was 28% (range 11-90%). Mean death in intensive care unit (ICU) was 42% (range 11-90%); and mean death rate in a hospital ward was 44.5% (range 29-60%). Mean prevalence of active measures including dialysis, radiotherapy, transfusions and life support treatment to terminal patient was 7-77% (mean 30%). Non-beneficial administration of antibiotics, cardiovascular, digestive and endocrine treatments to dying patients occurred in 11-75% (mean 38%). Non-beneficial tests were performed on 33-50% of patients with do-not-resuscitate orders. From meta-analyses, the pooled prevalence of non-beneficial ICU admission was 10% (95% CI 0-33%); for chemotherapy in the last six weeks of life was 33% (95% CI 24-41%).

CONCLUSION

This review has confirmed widespread use of NBTs at the EOL in acute hospitals. While a certain level of NBT is inevitable, its extent, variation and justification need further scrutiny.

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.

Prescribing for older people discharged from the acute sector to residential aged-care facilities

For frail older people, admission to hospital is an opportunity to review the indications for specific medications. This research investigates prescribing for 206 older people discharged into residential aged care facilities from 11 acute care hospitals in Australia. Patients had multiple comorbidities (mean 6), high levels of dependency, and were prescribed a mean of 7.2 regular medications at admission to hospital and 8.1 medications on discharge, with hyper-polypharmacy (≥10 drugs) increasing from 24.3% to 32.5%. Many drugs were preventive medications whose time until benefit was likely to exceed the expected lifespan. In summary, frail patients continue to be exposed to extensive polypharmacy and medications with uncertain risk-benefit ratio.

Polypharmacy among inpatients aged 70 years or older in Australia

OBJECTIVES

To investigate medication changes for older patients admitted to hospital and to explore associations between patient characteristics and polypharmacy.

DESIGN

Prospective cohort study.

PARTICIPANTS AND SETTING

Patients aged 70 years or older admitted to general medical units of 11 acute care hospitals in two Australian states between July 2005 and May 2010. All patients were assessed using the interRAI assessment system for acute care.

MAIN OUTCOME MEASURES

Measures of physical, cognitive and psychosocial functioning; and number of regular prescribed medications categorised into three groups: non-polypharmacy (0-4 drugs), polypharmacy (5-9 drugs) and hyperpolypharmacy (≥ 10 drugs).

RESULTS

Of 1220 patients who were recruited for the study, medication records at admission were available for 1216. Mean age was 81.3 years (SD, 6.8 years), and 659 patients (54.2%) were women. For the 1187 patients with complete medication records on admission and discharge, there was a small but statistically significant increase in mean number of regular medications per day between admission and discharge (7.1 v 7.6), while the prevalence of medications such as statins (459 [38.7%] v 457 [38.5%] patients), opioid analgesics (155 [13.1%] v 166 [14.0%] patients), antipsychotics (59 [5.0%] v 65 [5.5%] patients) and benzodiazepines (122 [10.3%] v 135 [11.4%] patients) did not change significantly. Being in a higher polypharmacy category was significantly associated with increase in comorbidities (odds ratio [OR], 1.27; 95% CI, 1.20-1.34), presence of pain (OR, 1.31; 1.05-1.64), dyspnoea (OR, 1.64; 1.30-2.07) and dependence in terms of instrumental activities of daily living (OR, 1.70; 1.20-2.41). Hyperpolypharmacy was observed in 290/1216 patients (23.8%) at admission and 336/1187 patients (28.3%) on discharge, and the proportion of preventive medication in the hyperpolypharmacy category at both points in time remained high (1209/3371 [35.9%] at admission v 1508/4117 [36.6%] at discharge).

CONCLUSIONS

Polypharmacy is common among older people admitted to general medical units of Australian hospitals, with no clinically meaningful change to the number or classification (symptom control, prevention or both) of drugs made by treating physicians.
