Delirium in palliative medicine: a review

Influence of dosing pattern of antipsychotics on treatment outcome of delirium in patients with advanced cancer

BACKGROUND

Clinical guidelines recommend antipsychotics for the treatment of delirium; however, there has been no confirmed recommendation regarding their administrating patterns. This study aims to investigate whether different dosing patterns of antipsychotics (single or multiple administrations) influence the outcomes of delirium treatment.

METHODS

This is a secondary analysis of a prospective observational study involving patients with advanced cancer and delirium receiving antipsychotics. The Delirium Rating Scale Revised-98 was administered at baseline and after 72 h of starting pharmacotherapy. Patients were classified into single administration group (received a single dosage within 24 h before the assessment) and multiple administration group (received more than one dosage).

RESULTS

A total of 555 patients (single administration 492 (88.6%); multiple administration 63 (11.4%)) were subjected to analyses. The patients in the multiple administration group were more likely to be male, in psycho-oncology consulting settings, with lower performance status, with hyperactive delirium and with severer delirium symptoms. In the multivariate analysis, single administration was significantly associated with better improvement of delirium (p < 0.01, 95% confidence interval: 1.83-5.87) even after controlling covariates. There were no significant differences in the mean dosages of antipsychotics per day in chlorpromazine equivalent (single administration 116.8 mg/day, multiple administration 123.5 mg/day) and the incidence of adverse events between the two groups.

CONCLUSIONS

In this observational study sample, Delirium Rating Scale severity score improvement in single administration was higher than that seen in multiple administration. There was no difference in adverse events between the two groups.

Palliative care for patients with advanced dementia

ABSTRACT

Dementia is currently the seventh leading cause of death and one of the major causes of disability and dependency among older adults globally. Its final stages are complicated by a multitude of problems that can cause immense suffering. This article explores the interconnection between advanced dementia and palliative care and the role of nurses in providing end-of-life care for these patients.

A Preliminary Scoring Model to Predict In-hospital Mortality Risk for Geriatric Patients with Delirium

BACKGROUND: Elderly patients are at an increased risk of death, particularly those with altered mental status. AIM: We aimed to develop a scoring model from simple clinical data and routine laboratory testing to aid in predicting in-hospital mortality risk for geriatric patients with delirium. METHODS: A total of 73 hospitalized geriatric patients with delirium were included in the study. A multivariate regression analysis employed to obtain independent risk factors to predict in-hospital mortality. All patients were followed until dead or discharged from hospital. The formula of (B/SE)/lowest B/SE was used to calculate the scores for each variable with strong discrimination power to be included in scoring system. RESULTS: A total of 25 (34.2%) of patients were death when being hospitalized. The mean age of the patients was 73.27 ± 7.8. From a total of 20 probable variables, three variables were then included in constructing the scoring model; no caregiver (p < 0.012), abnormal diastolic blood pressure (p < 0.05), and abnormal serum SGOT levels (p < 0.03). Each variable was scored as 1, following the use of formula. Total score ranges from 0 to maximum of 3. The cutoff score of ≥ 2 provided the best accuracy with sensitivity of 40% and specificity of 89.6% (p < 0.001). The probability of in-hospital mortality was 8.8%, 32.6%, 70.8%, and 92.4% for the total score of 0, 1, 2, and 3, respectively. CONCLUSION: This novel scoring system with simple examination may aid to identify geriatric patients with delirium which possess higher risk for in-hospital mortality.

Terminal Delirium in Hospice: The Experiences and Perspectives of Caregivers Providing Care to Terminally Ill Patients in Home Settings

OBJECTIVES

Little is known about the experiences of caregivers who provide care to persons with terminal delirium (TD) in home settings. This scarcity of information is suggestive that further research is needed about care for hospice patients with delirium in the home and community.

AIM

To elicit views, feelings, and end-of-life care experiences of primary caregivers assisting dying persons with TD in hospice at home.

DESIGN

Qualitative, exploratory, cross-sectional study design was chosen. In-depth semistructured interviews explored caregiver experiences in caring for persons with TD. Qualitative thematic framework analysis was used.

PARTICIPANTS

Fifteen bereaved adult primary caregivers who received services from a hospice care program affiliated with a large nonprofit health system in the US Midwest.

RESULTS

Caregiver experiences were broad and reflected 4 major themes: symptomology, coping, effective and noneffective interventions, and support. The most distressing factors for caregivers were behaviors and symptomology of TD. They did not know what to say, how to respond, and how best to behave with someone who had delirium. Many caregivers had the impression that medication does not lessen delirium symptoms and that nonpharmacologic interventions are effective and beneficial only when they were important and meaningful to patients before delirium onset.

CONCLUSIONS

This study added new knowledge from direct and personal perspectives of caregivers providing end-of-life care to patients at home. Understanding developed about provision of care to someone with TD in home hospice. Improved comprehension of caregiver experiences can help professional hospice and palliative care staff better prepare caregivers for when patients have TD.

Death in delirious palliative-care patients occurs irrespective of age: A prospective, observational cohort study of 229 delirious palliative-care patients

Objectives

Patients with terminal illness are at high risk of developing delirium, in particular, those with multiple predisposing and precipitating risk factors. Delirium in palliative care is largely under-researched, and few studies have systematically assessed key aspects of delirium in elderly, palliative-care patients.

Methods

In this prospective, observational cohort study at a tertiary care center, 229 delirious palliative-care patients stratified by age: <65 (N = 105) and ≥65 years (N = 124), were analyzed with logistic regression models to identify associations with respect to predisposing and precipitating factors.

Results

In 88% of the patients, the underlying diagnosis was cancer. Mortality rate and median time to death did not differ significantly between the two age groups. No inter-group differences were detected with respect to gender, care requirements, length of hospital stay, or medical costs. In patients ≥65 years, exclusively predisposing factors were relevant for delirium, including hearing impairment [odds ratio (OR) 3.64; confidence interval (CI) 1.90–6.99; P < 0.001], hypertension (OR 3.57; CI 1.84–6.92; P < 0.001), and chronic kidney disease (OR 4.84; CI 1.19–19.72; P = 0.028). In contrast, in patients <65 years, only precipitating factors were relevant for delirium, including cerebral edema (OR 0.02; CI 0.01–0.43; P = 0.012).

Significance of results

The results of this study demonstrate that death in delirious palliative-care patients occurs irrespective of age. The multifactorial nature and adverse outcomes of delirium across all age in these patients require clinical recognition. Potentially reversible factors should be detected early to prevent or mitigate delirium and its poor survival outcomes.

Psychiatric comorbidities in cancer patients: acute interventions by the psychiatric consultation liaison service

AIM

The aim of this study was to explore the psychiatric comorbidities in cancer patients examined by the psychiatric consultation liaison services (CLP) in a general hospital. Furthermore, we intended to examine associations between certain cancers types and psychiatric disorders as well as to give an overview of the psychiatric treatments options that were recommended by the CLP.

METHODS

This retrospective analysis investigated 119 psychiatric consultations for cancer patients in a one year period. The assessment covered demographics and cancer diagnosis, psychiatric diagnosis and proceedings.

RESULTS

One third of all patients were treated for hematological cancer, followed by lung cancer. Depression was the most common psychiatric disorder. One third of all patients with hematological cancer were diagnosed with depression, followed by delirium. Inpatient psychiatric treatment and psychotherapy were most commonly recommended by the consultant psychiatrist. Furthermore, 80.2% of all patients received recommendations for medication with antidepressants.

CONCLUSION

Our data showed that the CLP provides an important service of detecting and initiating early and appropriate treatment for cancer patients with comorbid psychiatric disorders by directing patients to the relevant treatment procedure or facility.

The role of geriatric palliative care in hospitalized older adults

Take-Away Points:1. Geriatric palliative care requires integrating the disciplines of hospital medicine and palliative care in pursuit of delivering comprehensive, whole-person care to aging patients with serious illnesses.2. Older adults have unique palliative care needs compared to the general population, different prevalence and intensity of symptoms, more frequent neuropsychiatric challenges, increased social needs, distinct spiritual, religious, and cultural considerations, and complex medicolegal and ethical issues.3. Hospital-based palliative care interdisciplinary teams can take many forms and provide high-quality, goal-concordant care to older adults and their families.

Post-traumatic Stress Disorder Following Acute Delirium

Delirium is a significant medical condition that is common in hospitalized patients. Beyond the increased risk of mortality, patients who experience an episode of delirium often go on to develop long-term psychiatric disturbance, including symptoms of post-traumatic stress disorder (PTSD). While there is a growing interest in understanding the complex relationship between delirium and PTSD, the existing literature is sparse and lacking harmony. Thus, this review seeks to develop a unified and thorough description of the cognitive and psychiatric underpinnings of post-delirium PTSD with the aims of promoting awareness of this condition amongst clinicians in medical settings, improving patient care, and sparking further research on this topic. While specific underlying mechanisms are yet unclear, PTSD was found to be associated with delirium in that delirious patients may have decreased factual recall of hospital events and increased hallucinations/delusions of a traumatic nature. Several potential interventions were identified, as well as suggestions for future research and clinical practice.

Reversibility of delirium in Ill-hospitalized cancer patients: Does underlying etiology matter?

Background

The objective of this study was to explore the underlying etiologies associated with the resolution and improvement of delirium in ill‐hospitalized cancer patients.

Methods

We conducted a secondary analysis of a multicenter, prospective, observational study to estimate the effectiveness of pharmacotherapy for delirium. Participants were cancer patients with delirium. We assessed the Delirium Rating Scale, Revised‐98 (DRS‐R98) severity scale score at baseline and three days after pharmacotherapy initiation. Delirium resolution was defined as a DRS‐R98 severity scale score ≤9, and improvement was defined as ≥50% reduction at Day 3.

Results

We enrolled 566 patients (491 patients had performance status of 3 or 4). The resolution and improvement rates in all patients were 22.6% and 19.3%, respectively. Univariate analysis determined that nonrespiratory infection (OR 2.18, 95% CI 1.38‐3.45) was significantly associated with greater resolution, while dehydration (0.40, 0.19‐0.87), organic damage to the central nervous system (CNS) (0.32, 0.43‐0.72), hypoxia (0.25, 0.12‐0.52), and hyponatremia (0.34, 0.12‐0.97) were significantly associated with no resolution. Potential causes associated with delirium improvement were nonrespiratory infection (1.93, 1.19‐3.13), organic damage to the CNS (0.40, 0.18‐1.90), and hypoxia (0.32, 0.16‐0.65). After multivariate analysis, dehydration (0.34, 0.15‐0.76), organic damage to the CNS (0.25, 0.10‐0.60), and hypoxia (0.29, 0.14‐0.61) were significantly associated with no resolution.

Conclusions

Delirium caused by nonrespiratory infection may be reversible, while delirium associated with dehydration, organic damage to the CNS, hypoxia, or hyponatremia seems to be irreversible in ill‐hospitalized cancer patients.

A research study review of effectiveness of treatments for psychiatric conditions common to end-stage cancer patients: needs assessment for future research and an impassioned plea

BACKGROUND

Rates of psychiatric conditions common to end-stage cancer patients (delirium, depression, anxiety disorders) remain unchanged. However, patient numbers have increased as the population has aged; indeed, cancer is a chief cause of mortality and morbidity in older populations. Effectiveness of psychiatric interventions and research to evaluate, inform, and improve interventions is critical to these patients' care. This article's intent is to report results from a recent review study on the effectiveness of interventions for psychiatric conditions common to end-stage cancer patients; the review study assessed the state of research regarding treatment effectiveness. Unlike previous review studies, this one included non-traditional/alternative therapies and spirituality interventions that have undergone scientific inquiry.

METHODS

A five-phase systematic strategy and a theoretic grounded iterative methodology were used to identify studies for inclusion and to craft an integrated, synthesized, comprehensive, and reasonably current end-product.

RESULTS

Psychiatric medication therapies undoubtedly are the most powerful treatments. Among them, the most effective (i.e., "best practices benchmarks") are: (1) for delirium, typical antipsychotics-though there is no difference between typical vs. atypical and other antipsychotics, except for different side-effect profiles, (2) for depression, if patient life expectancy is ≥4-6 weeks, then a selective serotonin reuptake inhibitor (SSRI), and if < 3 weeks, then psychostimulants or ketamine, and these generally are useful anytime in the cancer disease course, and (3) for anxiety disorders, bio-diazepams (BDZs) are most used and most effective. A universal consensus suggests that psychosocial (i.e., talk) therapy and spirituality interventions fortify the therapeutic alliance and psychiatric medication protocols. However, trial studies have had mixed results regarding effectiveness in reducing psychiatric symptoms, even for touted psychotherapies.

CONCLUSIONS

This study's findings prompted a testable linear conceptual model of co-factors and their importance for providing effective psychiatric care for end-stage cancer patients. The complicated and tricky part is negotiating patients' diagnoses while articulating internal intricacies within and between each of the model's co-factors. There is a relative absence of scientifically derived information and need for more large-scale, diverse scientific inquiry. Thus, this article is an impassioned plea for accelerated study and better care for end-stage cancer patients' psychiatric conditions.

Relational ethics of delirium care: Findings from a hospice ethnography

Delirium, a common syndrome in terminally ill people, presents specific challenges to a good death in end-of-life care. This paper examines the relational engagement between hospice nurses and their patients in a context of end-of-life delirium. Ethnographic fieldwork spanning 15 months was conducted at a freestanding residential hospice in eastern Canada. A shared value system was apparent within the nursing community of hospice; patients' comfort and dignity were deemed most at stake and therefore commanded nurses' primary attention. This overarching commitment to comfort and dignity shaped all of nursing practice in this hospice, including practices related to end-of-life delirium. The findings of this study elaborate the ways in which hospice nurses interpreted and responded to the discomfort of their patients in delirium, as well as the efforts they made to understand their patients' subjective experiences and to connect with them in supportive ways. In addition to what is already known about clinical assessment and treatment of delirium in palliative care settings, the findings of this study offer points of reflection for nurses anywhere who are contending with the relational challenges that delirium presents in end-of-life care.

Propofol-Based Palliative Sedation to Treat Antipsychotic-Resistant Agitated Delirium

Delirium is a common problem in terminally ill patients that is associated with significant distress and, hence, considered a palliative care emergency. The three subtypes of delirium are hyperactive, hypoactive, and mixed, depending on the level of psychomotor activity and arousal disturbance. When agitated delirium becomes refractory in the setting of imminent dying, the agitation may be so severe that palliative sedation (PS) is required. Palliative sedation involves the administration of sedative medications with the purpose of reducing level of consciousness for patients with refractory suffering in the setting of a terminal illness. Propofol is a sedative that has a short duration of action and a very rapid onset. These characteristics make it relatively easy to titrate. Reported doses range from 50 to 70 mg per hour. The authors present a case of antipsychotic-resistant agitated delirium treated with a propofol intravenous infusion.

Care at the Very End-of-Life: Dying Cancer Patients and Their Chosen Family's Needs

The majority of cancer deaths in countries such as Australia are predictable and most likely to occur in hospital. Despite this, hospitals remain challenged by providing the best care for this fragile cohort, often believing that care with palliative intent at the very end-of-life is not the best approach to care. Given the importance that dying patients place on excellent symptom control, failing to provide good end-of-life care is likely to be contrary to the wishes of the imminently dying patient and their family. This becomes even more significant when the impact of care on the bereavement outcomes of families is considered. Given the rising numbers of predicable hospital deaths, an urgent need to address this exists, requiring health professionals to be cognisant of specific care domains already identified as significant for both patients and those closest to them in knowledge, care and affection. This non-systematic review's aims are to summarise the symptoms most feared by people imminently facing death which is defined as the terminal phase of life, where death is imminent and likely to occur within hours to days, or very occasionally, weeks. Further, this paper will explore the incidence and management of problems that may affect the dying person which are most feared by their family. The final section of this work includes a brief discussion of the most significant issues that require attention.

Delirium as letting go: An ethnographic analysis of hospice care and family moral experience

BACKGROUND

Delirium is extremely common in dying patients and appears to be a major threat to the family's moral experience of a good death in end-of-life care.

AIM

To illustrate one of the ways in which hospice caregivers conceptualize end-of-life delirium and the significance of this conceptualization for the relationships that they form with patients' families in the hospice setting.

DESIGN

Ethnography.

SETTING/PARTICIPANTS

Ethnographic fieldwork was conducted at a nine-bed, freestanding residential hospice, located in a suburban community of Eastern Canada. Data collection methods included 15 months of participant observation, 28 semi-structured audio-recorded interviews with hospice caregivers, and document analysis.

RESULTS

Hospice caregivers draw on a culturally established framework of normal dying to help families come to terms with clinical end-of-life phenomena, including delirium. By offering explanations about delirium as a natural feature of the dying process, hospice caregivers strive to protect for families the integrity of the good death ideal.

CONCLUSION

Within hospice culture, there is usefulness to deemphasizing delirium as a pathological neuropsychiatric complication, in favor of acknowledging delirious changes as signs of normal dying. This has implications for how we understand the role of nurses and other caregivers with respect to delirium assessment and care, which to date has focused largely on practices of screening and management.

How do healthcare workers judge pain in older palliative care patients with delirium near the end of life?

Objective:

Pain and delirium are commonly reported in older people with advanced cancer. However, assessing pain in this population is challenging, and there is currently no validated assessment tool for this task. The present retrospective cohort study was conducted to understand how healthcare workers (HCWs; nurses and physicians) determine that older cancer patients with delirium are in pain.

Method:

We reviewed the medical records of consecutive palliative care inpatients, 65 years of age and above (N= 113), in order to identify patient-based cues used by HCWs to make pain judgments and to examine how the cues differ by delirium subtype and outcome.

Results:

We found that HCWs routinely make judgments about pain in older patients with delirium using a repertoire of strategies that includes patient self-report and observations of spontaneous and evoked behavior. Using these strategies, HCWs judged pain to be highly prevalent in this inpatient palliative care setting.

Significance of results:

These novel findings will inform the development of valid and reliable tools to assess pain in older cancer patients with delirium.

Medication use during end-of-life care in a palliative care centre

Background In end-of-life care, symptoms of discomfort are mainly managed by drug therapy, the guidelines for which are mainly based on expert opinions. A few papers have inventoried drug prescriptions in palliative care settings, but none has reported the frequency of use in combination with doses and route of administration. Objective To describe doses and routes of administration of the most frequently used drugs at admission and at day of death. Setting Palliative care centre in the Netherlands. Method In this retrospective cohort study, prescription data of deceased patients were extracted from the electronic medical records. Main outcome measure Doses, frequency and route of administration of prescribed drugs Results All regular medication prescriptions of 208 patients, 89 % of whom had advanced cancer, were reviewed. The three most prescribed drugs were morphine, midazolam and haloperidol, to 21, 11 and 23 % of patients at admission, respectively. At the day of death these percentages had increased to 87, 58 and 50 %, respectively. Doses of these three drugs at the day of death were statistically significantly higher than at admission. The oral route of administration was used in 89 % of patients at admission versus subcutaneous in 94 % at the day of death. Conclusions Nearing the end of life, patients in this palliative care centre receive discomfort-relieving drugs mainly via the subcutaneous route. However, most of these drugs are unlicensed for this specific application and guidelines are based on low level of evidence. Thus, there is every reason for more clinical research on drug use in palliative care.

Management of delirium in palliative care: a review

Delirium is a complex but common disorder in palliative care with a prevalence between 13 and 88 % but a particular frequency at the end of life (terminal delirium). By reviewing the most relevant studies (MEDLINE, EMBASE, PsycLit, PsycInfo, Cochrane Library), a correct assessment to make the diagnosis (e.g., DSM-5, delirium assessment tools), the identification of the possible etiological factors, and the application of multicomponent and integrated interventions were reported as the correct steps to effectively manage delirium in palliative care. In terms of medications, both conventional (e.g., haloperidol) and atypical antipsychotics (e.g., olanzapine, risperidone, quetiapine, aripiprazole) were shown to be equally effective in the treatment of delirium. No recommendation was possible in palliative care regarding the use of other drugs (e.g., α-2 receptors agonists, psychostimulants, cholinesterase inhibitors, melatonergic drugs). Non-pharmacological interventions (e.g., behavioral and educational) were also shown to be important in the management of delirium. More research is necessary to clarify how to more thoroughly manage delirium in palliative care.

Palliative and supportive care for glioma patients

The diagnosis of a brain tumor is a life-changing event for patients and families. High-grade gliomas are incurable and long-term survival remains limited. While low-grade glioma patients have better outcomes, their quality of life is often affected by a variety of symptoms as well. Helping glioma patients improve quality of life at all stages of illness is an important goal for the interdisciplinary care team. There is evidence from advanced lung cancer patients that early involvement of a palliative care team can improve patient's quality of life, symptom burden, and even survival and a similar approach benefits glioma patients as well. Patients with high-grade and low-grade glioma often suffer from significant symptom burden. We discuss how validated global symptom assessments and symptom-specific screening tools are useful to identify distressing symptoms. Seizures, fatigue, depression, and anxiety are some of the more common symptoms throughout the disease course and should be managed actively. Patients with glioma also have high symptom burden at the end of life and the majority lose decision-making capacity. Advance care planning conversations early in the disease course are essential to elicit the patient's wishes for end of life care and effective communication with surrogate decision makers during all stages of the disease helps ensure that those wishes are respected.

An analytical framework for delirium research in palliative care settings: integrated epidemiologic, clinician-researcher, and knowledge user perspectives

CONTEXT

Delirium often presents difficult management challenges in the context of goals of care in palliative care settings.

OBJECTIVES

The aim was to formulate an analytical framework for further research on delirium in palliative care settings, prioritize the associated research questions, discuss the inherent methodological challenges associated with relevant studies, and outline the next steps in a program of delirium research.

METHODS

We combined multidisciplinary input from delirium researchers and knowledge users at an international delirium study planning meeting, relevant literature searches, focused input of epidemiologic expertise, and a meeting participant and coauthor survey to formulate a conceptual research framework and prioritize research questions.

RESULTS

Our proposed framework incorporates three main groups of research questions: the first was predominantly epidemiologic, such as delirium occurrence rates, risk factor evaluation, screening, and diagnosis; the second covers pragmatic management questions; and the third relates to the development of predictive models for delirium outcomes. Based on aggregated survey responses to each research question or domain, the combined modal ratings of "very" or "extremely" important confirmed their priority.

CONCLUSION

Using an analytical framework to represent the full clinical care pathway of delirium in palliative care settings, we identified multiple knowledge gaps in relation to the occurrence rates, assessment, management, and outcome prediction of delirium in this population. The knowledge synthesis generated from adequately powered, multicenter studies to answer the framework's research questions will inform decision making and policy development regarding delirium detection and management and thus help to achieve better outcomes for patients in palliative care settings.

Caring for people dying in acute hospitals: A mixed-methods study to examine relative's perceptions of care

Objective:

Improving the care provided for people dying in acute healthcare facilities has been identified as a priority for Australian healthcare. Previous observations support the idea that quality care improves outcomes for the dying person as well as for their relatives. To improve care it is essential that there be a clear understanding of which issues require attention. The aim of our project was to improve the understanding of the experiences of family members whose relatives had died on an acute medical ward.

Method:

A mixed-methods approach was adopted for our study. With the approval of the human ethics committee, relatives were approached within three months of the death of their family member and invited to participate in an interview based on a quality-of-dying-and-death (QoDD) tool.

Results:

Of the 50 families approached, 10 agreed to be interviewed. When they were asked to reflect on the experiences of the dying person, the issues that they articulated most strongly related to the need to have time before death to address issues and spend time with important others. With regards to the needs of the dying person's relatives, people articulated strongly that they needed information, support, and evidence of good symptom control. The provision of support post-death was also poignantly highlighted.

Significance of Results:

This study supports observations made in other clinical areas that have identified that timely communication, good symptom control, and ongoing support for both the dying person and their family has important ramifications. Articulating such details is an important part of understanding which aspects of care require attention.

Mixed-methods approach to understanding nurses' clinical reasoning in recognizing delirium in hospitalized older adults

A mixed-methods study was conducted to enhance understanding of nurses' clinical reasoning in recognizing delirium in the hospitalized older adult. Paired nurse and researcher ratings of the confusion assessment method in 103 medical-surgical patients were analyzed to determine the rate of agreement in detecting delirium and to identify a purposive sample of nurses to be interviewed about the patients with delirium who were under their care. Nurses' clinical reasoning in recognizing and underrecognizing delirium was investigated using semistructured interviews. The incidence of delirium was 13%, with poor agreement (95% CI [0.05, 0.64], p < 0.05) between the researchers and the nurses in detecting delirium. Sixteen nurses were interviewed and transcripts were analyzed with grounded theory. Confusion was the primary causal factor for recognizing symptoms of delirium. The findings explicated a framework that forms the basis for generating testable assumptions to improve nurses' recognition of delirium.

Efficacy and safety of pharmacotherapy in cancer-related psychiatric disorders across the trajectory of cancer care: a review

At least 25-30% of patients with cancer and an even higher percentage of patients in an advanced phase of illness meet the criteria for a psychiatric diagnosis, including depression, anxiety, stress-related syndromes, adjustment disorders, sleep disorders and delirium. A number of studies have accumulated over the last 35 years on the use of psychotropic drugs as a pillar in the treatment of psychiatric disorders. Major advances in psycho-oncology research have also shown the efficacy of psychotropic drugs as adjuvant treatment of cancer-related symptoms, such as pain, hot flushes, pruritus, nausea and vomiting, fatigue, and cognitive impairment. The knowledge about pharmacokinetics and pharmacodynamics, clinical use, safety, side effects and efficacy of psychotropic drugs in cancer care is essential for an integrated and multidimensional approach to patients treated in different settings, including community-based centres, oncology, and palliative care. A search of the major databases (MEDLINE, Embase, PsycLIT, PsycINFO, the Cochrane Library) was conducted in order to summarize relevant data concerning the efficacy and safety of pharmacotherapy for cancer-related psychiatric disorders in cancer patients across the trajectory of the disease.
