Use of the CAGE questionnaire for screening problem drinking in an out-patient palliative radiotherapy clinic

A systematic review of assessment approaches to predict opioid misuse in people with cancer

Context

Cancer prevalence is increasing, with many patients requiring opioid analgesia. Clinicians need to ensure patients receive adequate pain relief. However, opioid misuse is widespread, and cancer patients are at risk.

Objectives

This study aims (1) to identify screening approaches that have been used to assess and monitor risk of opioid misuse in patients with cancer; (2) to compare the prevalence of risk estimated by each of these screening approaches; and (3) to compare risk factors among demographic and clinical variables associated with a positive screen on each of the approaches.

Methods

Medline, Cochrane Controlled Trial Register, PubMed, PsycINFO, and Embase databases were searched for articles reporting opioid misuse screening in cancer patients, along with handsearching the reference list of included articles. Bias was assessed using tools from the Joanna Briggs Suite.

Results

Eighteen studies met the eligibility criteria, evaluating seven approaches: Urine Drug Test (UDT) (n = 8); the Screener and Opioid Assessment for Patients with Pain (SOAPP) and two variants, Revised and Short Form (n = 6); the Cut-down, Annoyed, Guilty, Eye-opener (CAGE) tool and one variant, Adapted to Include Drugs (n = 6); the Opioid Risk Tool (ORT) (n = 4); Prescription Monitoring Program (PMP) (n = 3); the Screen for Opioid-Associated Aberrant Behavior Risk (SOABR) (n = 1); and structured/specialist interviews (n = 1). Eight studies compared two or more approaches. The rates of risk of opioid misuse in the studied populations ranged from 6 to 65%, acknowledging that estimates are likely to have varied partly because of how specific to opioids the screening approaches were and whether a single or multi-step approach was used. UDT prompted by an intervention or observation of aberrant opioid behaviors (AOB) were conclusive of actual opioid misuse found to be 6.5–24%. Younger age, found in 8/10 studies; personal or family history of anxiety or other mental ill health, found in 6/8 studies; and history of illicit drug use, found in 4/6 studies, showed an increased risk of misuse.

Conclusions

Younger age, personal or familial mental health history, and history of illicit drug use consistently showed an increased risk of opioid misuse. Clinical suspicion of opioid misuse may be raised by data from PMP or any of the standardized list of AOBs. Clinicians may use SOAPP-R, CAGE-AID, or ORT to screen for increased risk and may use UDT to confirm suspicion of opioid misuse or monitor adherence. More research into this important area is required.

Significance of results

This systematic review summarized the literature on the use of opioid misuse risk approaches in people with cancer. The rates of reported risk range from 6 to 65%; however, true rate may be closer to 6.5–24%. Younger age, personal or familial mental health history, and history of illicit drug use consistently showed an increased risk of opioid misuse. Clinicians may choose from several approaches. Limited data are available on feasibility and patient experience.

Fit and Tipsy? The Interrelationship between Cardiorespiratory Fitness and Alcohol Consumption and Dependence

PURPOSE

To examine whether higher levels of cardiorespiratory fitness are related to increased alcohol consumption and dependence among a large sample of adults attending a preventive medicine clinic.

METHODS

A cross-sectional study of 38,653 apparently healthy patients who visited the Cooper Clinic (Dallas, TX) for preventive medical examinations (1988-2019) and enrolled in the Cooper Center Longitudinal Study. The primary independent variable was cardiorespiratory fitness, based on a maximal treadmill test, and the dependent variables were alcohol consumption and dependence (self-reported). The relations between fitness category (low, moderate, high) and alcohol consumption (low, moderate, heavy) and suggested alcohol dependence (Cut down, Annoyed, Guilty, Eye opener score ≥2) among women and men were estimated via multivariable regression while adjusting for covariates (e.g., age, birth year cohort, marital status, and body mass index).

RESULTS

Women within the moderate and high fitness categories had 1.58 (95% confidence interval [CI], 1.32-1.91) and 2.14 (95% CI, 1.77-2.58) greater odds of moderate/heavy alcohol consumption, respectively, in comparison to their low fitness counterparts. Similarly, moderate and high fit men had 1.42 (95% CI, 1.30-1.55) and 1.63 (95% CI, 1.49-1.80) times greater odds of moderate-to-heavy alcohol consumption, respectively, in comparison to the low fitness group. In addition, among men who were heavy drinkers (but not women), higher fitness levels were related to lower rates of suggested alcohol dependence. Specifically, these men had 45.7%, 41.7%, and 34.9% proportions of clinically relevant alcohol problems across low, moderate, and high fitness categories (adjusted P for trend <0.001).

CONCLUSIONS

Higher fitness levels are significantly related to greater alcohol consumption among a large cohort of adult patients. Interventions focusing on increasing fitness (via physical activity promotion) might consider concurrently aiming to reduce alcohol consumption.

Palliative care for patients with a substance use disorder and multiple problems: a study protocol

BACKGROUND

The specific palliative care needs and problems of patients with a substance use disorder and multiple problems, and those of their proxies, are under recognized Besides, the organization of palliative care, including the division of health care professionals' responsibilities, is often unclear. Perspectives of patients and proxies are hardly known. We describe the outline of a study designed to explore how palliative care for patients with a substance use disorder is organized in the Netherlands and to explore problems and needs, as well as possible improvements from the healthcare professionals', patients' and proxies' perspective. The aim of this protocol paper is to provide insights in ways to conduct research with vulnerable research participants and to offer a detailed description of the study design. The broader study aims to gain insight in and formulate recommendations on how to improve palliative care for patients with a substance use disorder.

METHODS

A qualitative study with patients, proxies and healthcare professionals. Semi-structured interviews will be held with 10-15 patients who suffer from a severe substance use disorder. They are in a palliative care trajectory and either diagnosed with a chronic or life-threatening disease or, as a result of addictive behavior, a physical deterioration without the prospect of cure. Semi-structured interviews will also be held with 5-10 proxies. Healthcare professionals, volunteers and/or 'experts-by-experience' (n = 24-40) will be participating in semi-structured group interviews. All (group) interviews will be thematically analyzed. Additionally, a strengths, weaknesses, opportunities and threats (SWOT) analysis will be applied to the group interview data with the aim to summarize and concretize the findings.

DISCUSSION

Everyone has a right to an optimal end-of-life phase of life and a dignified dying process. This study will provide valuable knowledge about palliative care for patients with a substance use disorder and explicitly bring to light the needs and problems of the patients and their proxies and healthcare professionals in a palliative care phase.

Prevalence and characteristics of breakthrough cancer pain in an outpatient clinic in a Catalan teaching hospital: incorporation of the Edmonton Classification System for Cancer pain into the diagnostic algorithm

BACKGROUND

Breakthrough cancer pain (BTcP) is defined according to its principal characteristics: high intensity, short time interval between onset and peak intensity, short duration, potential recurrence over 24 h and non-responsiveness to standard analgesic regimes. The Edmonton Classification System for Cancer Pain (ECS-CP) is a classification tool that evaluates different dimensions of pain. The aim of this study was to measure prevalence and the main characteristics of BTcP in a sample of advanced cancer patients and to explore the complexity observed when ECS-CP is incorporated into BTcP diagnostics algorithm.

METHODS

Descriptive prevalence study (Retrospective chart review). Davies' algorithm was used to identify BTcP and ECS-CP was used to recognize appropriate dimensions of pain. The study was conducted in a sample of advanced cancer patients attending hospital outpatient clinic in Lleida, Spain. 277 patients were included from 01/01/2014 to 31/12/2015. No direct contact was made with participants. The following information was extracted from the palliative care outpatient clinic database: age, gender, civil status, cognitive impairment status, functional performance status and variables related to tumour. Only BTcP cases were included.

RESULTS

Prevalence of BTcP was 39.34% (63.9% men). Mean of age was 68.2 years. Main diagnosis was lung cancer (n = 154; 31.6%). Metastases were diagnosed in 83% of the sample. 138 patients (49.8%) were diagnosed with 1 type of BTcP and 139 (50.2%) were diagnosed with more than one type of BTcP. In total, 488 different types of BTcP were recorded (mean 1.75 ± 0, 9), 244 of these types (50%) presented a component of neuropathic pain. Addictive behaviour, measured through CAGE test, was present in 29.2% (N = 81) of the patients and psychological distress was present in 40.8% (n = 113).

CONCLUSIONS

Prevalence of BTcP (39.34%) is similar to the one reflected in the existing literature. Study results indicate that the routine use of ECS-CP in a clinical setting allows us to detect more than one type of BTcP as well as additional complexity associated with pain (neuropathic, addictive behavior and psychological distress).

A systematic review of the risk factors for clinical response to opioids for all-age patients with cancer-related pain and presentation of the paediatric STOP pain study

BACKGROUND

Inter-patient variability in response to opioids is well known but a comprehensive definition of its pathophysiological mechanism is still lacking and, more importantly, no studies have focused on children. The STOP Pain project aimed to evaluate the risk factors that contribute to clinical response and adverse drug reactions to opioids by means of a systematic review and a clinical investigation on paediatric oncological patients.

METHODS

We conducted a systematic literature search in EMBASE and PubMed up to the 24th of November 2016 following Cochrane Handbook and PRISMA guidelines. Two independent reviewers screened titles and abstracts along with full-text papers; disagreements were resolved by discussion with two other independent reviewers. We used a data extraction form to provide details of the included studies, and conducted quality assessment using the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies.

RESULTS

Young age, lung or gastrointestinal cancer, neuropathic or breakthrough pain and anxiety or sleep disturbance were associated to a worse response to opioid analgesia. No clear association was identified in literature regarding gender, ethnicity, weight, presence of metastases, biochemical or hematological factors. Studies in children were lacking. Between June 2011 and April 2014, the Italian STOP Pain project enrolled 87 paediatric cancer patients under treatment with opioids (morphine, codeine, oxycodone, fentanyl and tramadol).

CONCLUSIONS

Future studies on cancer pain should be designed with consideration for the highlighted factors to enhance our understanding of opioid non-response and safety. Studies in children are mandatory.

The effects of alcoholism and smoking on advanced cancer patients admitted to an acute supportive/palliative care unit

AIM

The aim of this prospective study was to determine the characteristics and symptom burden of advanced cancer patients with alcoholism problems and smoking, who were referred to an acute palliative/supportive care unit (ASPCU) of a comprehensive cancer center.

METHODS

Patients' characteristics, indications for admission, kind of admission, awareness of prognosis, and anticancer treatments were recorded. The Edmonton Symptom Assessment Scale (ESAS) was used to assess physical and psychological symptoms, and the CAGE questionnaire for the diagnosis of alcoholism. Patients were also divided in three groups: persistent smokers (PS), former smokers (FS), and non-smokers (NS). The Memorial Delirium Assessment Scale (MDAS) was used to assess the cognitive status of patients. Analgesic drugs and their doses at admission and discharge were recorded, as well opioid escalation index during hospital stay.

RESULTS

Three hundred fourteen consecutive cancer patients were surveyed. Forty-seven (14.9%), 143 (45.5%), and 124 (39.5%) subjects were PS-patients, FS-patients, and NS-patients, respectively. Sixteen patients were CAGE-positive. Females were more frequently NS, while males were more frequently FS (p = 0.0005). Statistical differences were also observed in disease awareness among the categories of smoking (p = 0.048). No statistical differences were found in ESAS items, except for drowsiness at T0 in NS-patients. Differences were found in OME and OEI, although the large variability of data did not determined a statistical difference. Higher values of nausea (at T0, p = 0.0005), dyspnea (at T0 and TX, p = 0.08 and 0.023, respectively), and well-being (at TX p = 0.003) were reported in CAGE-positive patients. No correlation was found between CAGE-positive patients and smokers.

CONCLUSION

Although smoking and alcoholism have obvious implications in advanced cancer patients, data remain controversial, as present data did provide limited data to confirm risk factors for advanced cancer patients. Clinical response was not strongly influenced by these risk factors.

Identifying and assessing the risk of opioid abuse in patients with cancer: an integrative review

Background

The misuse and abuse of opioid medications in many developed nations is a health crisis, leading to increased health-system utilization, emergency department visits, and overdose deaths. There are also increasing concerns about opioid abuse and diversion in patients with cancer, even at the end of life.

Aims

To evaluate the current literature on opioid misuse and abuse, and more specifically the identification and assessment of opioid-abuse risk in patients with cancer. Our secondary aim is to offer the most current evidence of best clinical practice and suggest future directions for research.

Materials and methods

Our integrative review included a literature search using the key terms “identification and assessment of opioid abuse in cancer”, “advanced cancer and opioid abuse”, “hospice and opioid abuse”, and “palliative care and opioid abuse”. PubMed, PsycInfo, and Embase were supplemented by a manual search.

Results

We found 691 articles and eliminated 657, because they were predominantly non cancer populations or specifically excluded cancer patients. A total of 34 articles met our criteria, including case studies, case series, retrospective observational studies, and narrative reviews. The studies were categorized into screening questionnaires for opioid abuse or alcohol, urine drug screens to identify opioid misuse or abuse, prescription drug-monitoring programs, and the use of universal precautions.

Conclusion

Screening questionnaires and urine drug screens indicated at least one in five patients with cancer may be at risk of opioid-use disorder. Several studies demonstrated associations between high-risk patients and clinical outcomes, such as aberrant behavior, prolonged opioid use, higher morphine-equivalent daily dose, greater health care utilization, and symptom burden.

The frequency of alcoholism in patients with advanced cancer admitted to an acute palliative care unit and a home care program

CONTEXT

Cancer patients with a history of alcoholism may be problematic. The frequency of alcoholism among patients with advanced cancer has never been reported in Italy or other European countries.

OBJECTIVES

The aim of this prospective study was to determine the frequency of alcoholism, assessed with a simple and validated instrument, among patients with advanced cancer who were referred to two different palliative care settings: an acute inpatient palliative care unit (PCU) of a comprehensive cancer center in a metropolitan area and a home care program (HCP) in a territorial district, localized in the mountains of Italy.

METHODS

A consecutive sample of patients admitted to an inpatient PCU and to an HCP was assessed for a period of eight months. Each patient who agreed to be interviewed completed the Cut down, Annoyed, Guilty, Eye-opener (CAGE) questionnaire. Patients were then interviewed informally to gather information about their history with alcohol.

RESULTS

In total, 443 consecutive patients were surveyed; data from 249 to 194 patients were collected in the PCU and HCP, respectively, in the eight-month period. The mean age was 66.4 (SD 12.7) years, and 207 were males. The mean Karnofsky level was 54.2 (SD 14.6). Eighteen patients were CAGE positive (4.06%). Males (Pearson Chi-squared, P = 0.027) and younger patients (analysis of variance test, P = 0.009) were more likely to be CAGE positive. Informal interviews revealed that 17 patients (3.83%) were alcoholics or had a history of alcoholism, and that alcoholism was strongly correlated with CAGE (Pearson Chi-squared, P < 0.0001).

CONCLUSION

Only a minority of patients were CAGE positive, with a similar frequency in the PCU and HCP settings. CAGE-positive patients were more likely to be male and younger, independent of diagnosis and performance status. CAGE was positively correlated with informal interviews for detecting alcoholism. As CAGE patients express more symptom distress, it is important to detect this problem with a simple tool that has a high sensitivity and specificity and is easy to use even in patients with advanced disease.

Palliative care for people with severe persistent mental illness: a review of the literature

A systematic overview of the literature on palliative care for people with severe persistent mental illness (SPMI) was conducted to inform clinical practice, research, and education. Empirical studies and nonempirical papers were included. Few empirical studies exist. There is even less information about the palliative care needs of, or the nature of palliative care provided to, people with SPMI. Mental health, primary care, and palliative care providers need to partner with people who have SPMI in developing and providing palliative care. The field of palliative care for people with SPMI is wide open and in need of methodologically sound studies that will help define the issues that exist for this vulnerable population. Recognizing the similarities between mental health and palliative care should lead to collaborative ventures and discussions in an attempt to address common and parallel issues.

Psychiatric disorders in advanced cancer

BACKGROUND

Emotional distress and psychiatric disorders are common among patients with advanced cancer. Oncologists play an important role in screening for these conditions, providing first-line treatment and referring patients for further evaluation and treatment when indicated.

METHODS

The literature on psycho-oncology was reviewed, focusing on the epidemiology, assessment, and treatment of psychiatric disorders (adjustment disorders, major depression, anxiety and post-traumatic stress, personality disorders, substance abuse, and major mental disorders such as schizophrenia and bipolar disorder) in patients with advanced cancer. Communication skills and the role of the oncologist in dealing with end-of-life issues were also reviewed. Relevant data were summarized from the most recent systematic reviews, epidemiological studies, and intervention trials. Clinical recommendations are provided.

RESULTS

About 50% of patients with advanced cancer meet criteria for a psychiatric disorder, the most common being adjustment disorders (11%-35%) and major depression (5%-26%). Both psychosocial and pharmacological treatments are effective for anxiety and depression, although existing studies have methodological limitations. Collaboration with mental health specialists is recommended for patients with personality disorders, major mental illness, and substance abuse problems. Effective communication involves active listening, exploring emotion and meaning, addressing prognosis, and discussing end-of-life issues when relevant.

CONCLUSIONS

Treating psychiatric conditions improves quality of life in patients with advanced cancer. Oncologists play a key role in screening for psychiatric disorders, initiating first-line treatments for depression and anxiety, and communicating with patients and caregivers about prognosis and end-of-life issues.

Psychological Issues in End-of-Life Care

This paper provides a systematic, evidence-based review of the psychological issues confronted by patients at the end of life, drawing on recent literature. The epidemiology, approach to clinical assessment, clinical presentation, and therapeutic options related to common psychological issues that arise in end-stage illness are described. The spectrum of normal and dysfunctional reactions are identified, and approaches to enhancing coping and quality of life are emphasized. The learner will be able to describe: (1) normal coping responses of patients at the end of life; (2) epidemiology of common psychiatric disorders at the end of life; (3) the approach to clinical assessment of psychological distress at the end of life; and (4) therapeutic approaches to common psychological problems at the end of life.

Patient appointment process, symptom control and prediction of follow-up compliance in a palliative care outpatient clinic

Activities and outcomes in an outpatient palliative care clinic (PCC) have attracted little attention in the literature. We describe the results of our patient appointment scheduling process, our efficacy in relieving cancer-associated symptoms and an analysis of risk factors for patient non-compliance with the appointment schedule. Over a one-year study period, 730 first-time appointments were scheduled and 73.1% of them were kept. Only patients who had kept 3 consecutive visits (n=203) were included in the symptom control analysis. All symptoms except constipation, physical weakness, and anxiety improved significantly with palliative care. History of alcohol abuse was not associated with poorer pain control. A low Karnofsky index and high anxiety levels were identified as risk factors for early withdrawal from the PCC scheduled appointment. These data indicate that the PCC is an effective place for symptom management, but specific organizational strategies are needed to encourage patients to comply with scheduled appointments.
