Pattern and characteristics of advanced cancer patients admitted to hospices in Italy

Acute palliative care units: characteristics, activities and outcomes - scoping review

Acute palliative care units (APCUs) are lacking in most cancer hospitals and even when palliative care units are present, they are predominantly based on a traditional hospice-like model for patients with short life expectancy. This scoping review examined the papers assessing the activities of APCU. Data from literature regarding APCU characteristics, activities and outcomes have shown important differences among different countries.In comparison with existing data on traditional hospices, APCU provided a whole range of palliative care interventions, from an early treatment of pain and symptoms at time diagnosis and during the oncological treatment, up to the advanced stage of disease when they may favour the transition to the best supportive care or palliative care only, also indicating the best palliative care service that may fits the clinical and social condition of individuals. Large differences in the characteristics of such units, including hospital stay and mortality, have been evidenced, in some cases resembling those of a traditional hospice. It likely that in some countries such units supply the lack of other palliative care services.Further studies on APCUs are needed, even on other outcome processes, to provide a more precise identification among the palliative care settings, which should not interchangeable, but complimentary to offer the full range of activities to be activated according to the different needs of the patients.

Pattern and characteristics of patients admitted to a hospice connected with an acute palliative care unit in a comprehensive cancer center

Purpose

Information about inpatient hospice activity is limited. No data exist about the pattern and the characteristics of advanced cancer patients admitted to a hospice connected to an acute supportive/palliative care unit (ASPCU).

Methods

Data of hospice admissions were retrieved from the database where all data were prospectively collected. The Edmonton Symptom Assessment Scale (ESAS) and the use of analgesics and adjuvant were recorded at admission (T0), 1 week (T7), 2 weeks (T14), and the day before death (T-end). The use of palliative sedation and its indication, duration, and drugs end doses used were recorded. The number of hospice deaths, discharges, and hospice staying were recorded.

Results

One hundred seventy-seven patients were admitted in 13 months. There were significant differences in total ESAS at T0 (P = 0.033), total ESAS being significantly lower in patients admitted from the ASPCU than those referred from other settings. The day before death (T-end), only 48 patients could be evaluated. Patients referred by a palliative care setting were more likely to be prescribed opioids at T0 (P = 0.0007). At T-end, there was a significant increase in the use of morphine and haloperidol (P < 0.05). Seventeen percent of patients died within 48 h. Only a minority of patients could be properly assessed at T-end (25%). Palliative sedation was performed in 10.1% of patients. The mean hospice staying was 16.3 (SD 21.4) days. There were no differences in mean hospice staying between patients who died in hospice or those discharged (P = 0.873).

Conclusion

The presence of a hospice in a comprehensive cancer center could offer a further opportunity for continuing care. Specialized palliative care may be offered to patients referred from other hospitals, home palliative care, but above all, transfer to hospice may allow a continuity of care for those patients who were initially admitted to an ASPCU for symptom control, to which anticancer therapies were withdrawn or withhold after multidisciplinary consultation. Similarly, after a proper palliative care consultation in other hospital units, patients may be referred to hospice. This process may avoid transfers to external hospices, which can prevent the continuity of care.

Palliative care organization and staffing models in residential hospices: Which makes the difference?

BACKGROUND

The number of patients using palliative care services, particularly residential hospices, is increasing. Policymakers are urging these services to reflect on the most effective organizational strategies for meeting patients' complex care needs.

AIM

To analyze the predictive power of staffing, structure and process indicators towards optimal control of patients' clinically significant symptoms over time.

DESIGN

Secondary analysis of data from a multicentre prospective longitudinal observational study (PRELUdiHO) collected between November 2017 and September 2018.

SETTING/PARTICIPANTS

Adult patients (n = 992) enrolled in 13 Italian residential hospices.

METHODS

Two generalized estimating equations logistic models were built, both with number of hospice beds and length of stay as independent variables as well as, in one case, patient-to-healthcare worker ratios, and, in the other, health professionals' qualification levels. Dependent variables were six not clinically significant (score<4) symptoms: pain, nausea, shortness of breath, feeling sad, feeling nervous, and 'how you feel overall', according to the Edmonton Symptom Assessment System revised (ESAS-r) scale.

RESULTS

The generalized estimating equations indicators on staff revealed the following 'optimal' model: Patient-to-Physician ratio (5.5:1-6.5:1); Patient-to-Nurse ratio (1.5:1-2.7:1); Patient-to-Nurse-Assistant ratio (4.1:1-6.3:1); with the most balanced staff composition including 19% physicians, 23% nurse assistants, and 58% registered nurses; hospice beds (12-25); length of stay (median = 12 days). This model predicted an up to four times greater likelihood of controlling all six ESAS-r symptoms over time. The generalized estimating equations model on the educational level of physicians and registered nurses showed that it was significantly associated with optimal patients' symptom control during the entire hospice stay.

CONCLUSIONS

This study showed the exact skill-mix composition and proportions of palliative care team able to ensure optimal control of patients' symptoms. The added value of physicians and nurses with a qualification in palliative care in terms of better patient outcomes reaffirmed the importance of education in guaranteeing quality care. Hospices with 12-25 beds, and recruitment methods guaranteeing at least 12-day stay ensured the most propitious organizational environment for optimal management of clinically significant symptoms. The transferability of these results mainly depends on whether the skills of health professionals in our `ideal' model are present in other contexts. Our results provide policymakers and hospice managers with specific, evidence-based information to support decision-making processes regarding hospice staffing and organization. Further prospective studies are needed to confirm the positive impact of this 'optimal' organizational framework on patient outcomes.

Duration of palliative care before death in international routine practice: a systematic review and meta-analysis

BACKGROUND

Early provision of palliative care, at least 3-4 months before death, can improve patient quality of life and reduce burdensome treatments and financial costs. However, there is wide variation in the duration of palliative care received before death reported across the research literature. This study aims to determine the duration of time from initiation of palliative care to death for adults receiving palliative care across the international literature.

METHODS

We conducted a systematic review and meta-analysis that was registered with PROSPERO (CRD42018094718). Six databases were searched for articles published between Jan 1, 2013, and Dec 31, 2018: MEDLINE, Embase, CINAHL, Global Health, Web of Science and The Cochrane Library, as well undertaking citation list searches. Following PRISMA guidelines, articles were screened using inclusion (any study design reporting duration from initiation to death in adults palliative care services) and exclusion (paediatric/non-English language studies, trials influencing the timing of palliative care) criteria. Quality appraisal was completed using Hawker's criteria and the main outcome was the duration of palliative care (median/mean days from initiation to death).

RESULTS

One hundred sixty-nine studies from 23 countries were included, involving 11,996,479 patients. Prior to death, the median duration from initiation of palliative care to death was 18.9 days (IQR 0.1), weighted by the number of participants. Significant differences between duration were found by disease type (15 days for cancer vs 6 days for non-cancer conditions), service type (19 days for specialist palliative care unit, 20 days for community/home care, and 6 days for general hospital ward) and development index of countries (18.91 days for very high development vs 34 days for all other levels of development). Forty-three per cent of studies were rated as 'good' quality. Limitations include a preponderance of data from high-income countries, with unclear implications for low- and middle-income countries.

CONCLUSIONS

Duration of palliative care is much shorter than the 3-4 months of input by a multidisciplinary team necessary in order for the full benefits of palliative care to be realised. Furthermore, the findings highlight inequity in access across patient, service and country characteristics. We welcome more consistent terminology and methodology in the assessment of duration of palliative care from all countries, alongside increased reporting from less-developed settings, to inform benchmarking, service evaluation and quality improvement.

Palliative Care in the Time of COVID-19

After COVID-19 crisis in Italy, serious restrictions have been introduced for relatives, with limitations or prohibitions on hospital visits. To partially overcome these issues "WhatsApp" has been adopted to get family members to participate in clinical rounds. Family members of patients admitted to the acute palliative care unit and hospice were screened for a period of two weeks. Four formal questions were posed: 1) Are you happy to virtually attend the clinical round? 2) Are you happy with the information gained in this occasion? 3) Do you think that your loved one was happy to see you during the clinical rounds? 4) This technology may substitute your presence during the clinical rounds? The scores were 0 = no, 1 = a little bit, 2 = much, 3 = very much. Relatives were free to comment about these points. Sixteen of 25 screened family members were interviewed. Most family members had a good impression, providing scores of 2 or 3 for the first three items. However, the real presence bedside (forth question) was considered irreplaceable. They perceived that their loved one, when admitted to hospice, had to say good-bye before dying.

Factors Influencing Clinical and Setting Pathways After Discharge From an Acute Palliative/Supportive Care Unit

AIM

The aim of this study was to assess the factors which influence the care pathway after discharge from an acute palliative supportive care unit (APSCU).

METHODS

Patients' demographics, indications for admission, kind of admission, the presence of a caregiver, awareness of prognosis, data on anticancer treatments in the last 30 days, ongoing treatment (on/off or uncertain), the previous care setting, analgesic consumption, and duration of admission were recorded. The Edmonton Symptom Assessment Scale (ESAS) at admission and at time of discharge (or the day before death), CAGE (cut down, annoy, guilt, eye-opener), and the Memorial Delirium Assessment Scale (MDAS), were used. At time of discharge, the subsequent referral to other care settings (death, home, home care, hospice, oncology), and the pathway of oncologic treatment were reconsidered (on/off, uncertain).

RESULTS

A total of 314 consecutive cancer patients admitted to the APSCU were surveyed. Factors independently associated with on-therapy were the lack of a caregiver, home discharge, and short hospital admission, in comparison with off-treatment, and less admission for other symptoms, shorter hospital admission, discharge at home, and better well-being, when compared with "uncertain." Similarly, many factors were associated with discharge setting, but the only factor independently associated with discharge home was being "on-therapy."

CONCLUSIONS

The finding of this study is consistent with an appropriate selection of patients after being discharged by an APSCU, that works as a bridge between active treatments and supportive/palliative care, according the concept of early and simultaneous care.

Health-Care Professionals Perceived Barriers to Effective Cancer Pain Management in the Home Hospice Setting: Is Dying at Home Really Best?

Hospice health-care professionals (HCP) evaluate and manage cancer pain in patient homes. This study explores HCP's perceptions of barriers that affect pain management for home hospice cancer patients. A convenience sample of 20 experienced hospice HCP were recruited from a regional hospice agency. Data were collected through two focus groups using semistructured interviews and analyzed using a constant comparative approach to generate themes. An unexpected finding revealed patient's religious and cultural beliefs about suffering and family caregiver's beliefs that patients deserve to suffer due to past actions are barriers to pain management in home hospice. Hospice HCP can identify patients at risk for suffering at the end of life. Interventions targeting spiritual suffering and needs are needed. Home hospice HCP have an ethical obligation to address undue suffering through family's withholding of necessary pain medications and should consider alternative placement when home is not suitable for a peaceful death.

Symptom expression in advanced cancer patients admitted to hospice or home care with and without delirium

The aim of this study is to investigate the relationship between delirium and symptom expression in advanced cancer patients admitted to palliative care services. This is a secondary analysis of a consecutive sample of advanced cancer patients who were admitted to home care and hospices, and prospectively assessed for a period of 10 months. The Edmonton Symptom Assessment Scale (ESAS) and the MDAS (Memorial Delirium Assessment Scale) were measured at admission (T0) and after seven days of home care or hospice care (T7). Of the eight hundred and forty-eight patients screened in the period, 585 were not considered in the analysis for various reasons. The mean age was 72.1 years (SD 13.7), and 146 patients were males (55.5%). The mean Karnofsky status recorded at T0 is 34.1 (SD = 6.69). The mean duration palliative care assistance is 38.4 days (SD = 48, range 2-220). Of 263 patients who had a MDAS available at T0, 110 patients (41.8%) had a diagnosis of delirium. Of them, 167 patients had complete data regarding MDAS measurement, either at T0 and T7. A larger number of patients (n 167, 63.5%) had delirium after a week of palliative care. Patients with delirium are likely to be older, to have a lower Karnofsky level at T0, and to be home care patients. At T0, weakness, nausea, drowsiness, lack of appetite, and well-being are associated with delirium. At T7, weakness, poor appetite, and poor well-being are significantly associated with delirium. 27% of patients who had a normal cognitive status at T0 developed delirium at T7. In patients with delirium, an improvement in the cognitive status corresponds to a significant improvement in weakness, depression, and appetite. Conversely, the occurrence of delirium in patients who had a normal cognitive status at admission significantly increases the level depression, while the level of weakness and appetite decrease. Symptom expression is amplified in patients with delirium admitted to home care or hospices, while patients without delirium can be more responsive to palliative treatments with a significant decrease in intensity of ESAS items.

Symptom Expression in Patients with Advanced Cancer Admitted to an Acute Supportive/Palliative Care Unit With and Without Delirium

AIM

The aim of this study was to investigate the relationship between delirium and symptom expression in patients with advanced cancer admitted to an acute supportive/palliative care unit (ASPCU).

METHODS

A consecutive sample of patients with advanced cancer who were admitted to an ASPCU was prospectively assessed for a period of 10 months. The Edmonton Symptom Assessment Scale (ESAS) and the MDAS (Memorial Delirium Assessment Scale) were measured at admission (T0) and after 7 days of palliative care (T7).

RESULTS

Two hundred forty-six patients had complete data regarding MDAS measurements, at either T0 and T7. Of these, 75 (30.5%) and 63 patients (25.6%) had delirium at T0 and after a week of palliative care (T7), with a decrease in the frequency of delirium of 4.9% (from 30.5% to 25.6%); that means that 16% of patients with delirium improved their cognitive status after initiation of palliative care. Intensities of pain, depression, poor well-being, and global ESAS were significantly higher in patients with delirium. Patients who did not have delirium at T0 but developed delirium during admission after 1 week of palliative care had a higher level of symptom expression for pain, weakness, nausea, anxiety, dyspnea, appetite, and consequently global ESAS. Patients who did not develop delirium at any time had a relevant decrease in intensity of all ESAS items after 1 week of palliative care. The decrease of symptom intensity was significant for pain, insomnia, appetite, poor well-being, and global ESAS in patients with delirium either at T0 and T7, although these differences were less relevant than those observed in patients without delirium. In patients with delirium at T0 who improved their cognitive function at T7 (no delirium), significant changes were found in most ESAS items.

CONCLUSION

Symptom expression is amplified in patients with delirium, whereas patients without delirium may be more responsive to palliative treatments with a significant decrease in intensity of ESAS items.

IMPLICATIONS FOR PRACTICE

Symptom expression is amplified in patients with cancer who have delirium, whereas patients without delirium may be more responsive to palliative treatments with a significant decrease in symptom intensity.

Prevalence of delirium in advanced cancer patients in home care and hospice and outcomes after 1 week of palliative care

AIM

The aim of this study was to assess the prevalence of delirium in advanced cancer patients admitted to different palliative care services in Italy and possible related factors. The secondary outcome was to assess the changes of delirium after 1 week of palliative care.

METHODS

A consecutive sample of patients was screened for delirium in period of 1 year in seven palliative care services. General data, including primary tumor, age, gender, concomitant disease, palliative prognostic score (PaP), and Karnofsky status, were collected. Possible causes or factors associated with delirium were looked for. The Edmonton Symptom Assessment Scale was used to assess physical and psychological symptoms and the Memorial Delirium Assessment Scale (MDAS) to assess the cognitive status of patients, at admission (T0) and 1 week after palliative care (T7).

RESULTS

Of 848 patients screened, 263 patients were evaluated. Sixty-six patients had only the initial evaluation. The mean Karnofsky status was 34.1 (SD = 6.69); the mean PaP score at admission was 6.9 (SD = 3.97). The mean duration of palliative care assistance, equivalent to survival, was 38.4 days (SD = 48, range 2-220). The mean MDAS values at admission and after 1 week of palliative care were 6.9 (SD = 6.71) and 8.8 (SD = 8.26), respectively. One hundred ten patients (41.8%) and 167 patients (67.3%) had MDAS values ≥ 7 at admission and after 1 week of palliative care, respectively. Age, dehydration, cachexia, chemotherapy in the last three months, and intensity of drowsiness and dyspnea were independently associated with a MDAS > 7. A worsening of drowsiness, the use of opioids, and the use of corticosteroids were independently associated with changes of MDAS from T0 to T7.

CONCLUSION

Although the prevalence of delirium seems to be similar to that reported in other acute settings, delirium tended to worsen or poorly responded to a palliative care treatment. Some clinical factors were independently associated with delirium. This information is relevant for decision-making when delirium does not change despite a traditional intervention. Continuous assessment of delirium should be performed in these settings to detect deterioration of cognitive function. Further studies should elucidate whether an earlier approach to palliative care would decrease the prevalence of delirium at a late stage of disease.

[Breakthrough cancer pain in the elderly]

Breakthrough pain is defined as an acute exacerbation of pain with rapid onset, short duration and moderate or high intensity, which occurs spontaneously or in connection with a predictable or unpredictable event despite there being stabilised and controlled baseline pain. However, there are doubts about the definition, terminology, epidemiology, and assessment of breakthrough pain, with no clear answers or consensus, especially in the elderly population. This non-systematic review summarises the most important aspects of breakthrough pain in the elderly, based on the limited publications there are in that population group.

Characteristics of patients with an unplanned admission to an acute palliative care unit

The aim of this cohort study is to compare the symptom burden of patients who have an unplanned admission to an acute palliative care unit (APCU) with patients who have a regular planned admission. A consecutive sample of advanced cancer patients who were admitted to an APCU was prospectively assessed. The reasons and the kind of admission were recorded (unplanned, UP, or planned, P). Anticancer treatments, whether patients were on/off treatment or uncertain, previous care setting, and who referred the patient to the unit were also recorded. The Edmonton Symptom Assessment Scale (ESAS) was used at admission and at time of discharge, as well as the Memorial Delirium Assessment Scale. Analgesics and their doses at admission and discharge were recorded. Hospital staying was also recorded. At the time of discharge, subsequent referral to other care settings, and the pathway of oncologic treatment were re-considered. Fifty-five (17.5%) of 314 consecutive admissions recorded in a period of 10 months were UP. UP-patients are more frequently referred from other hospitals (P = 0.0005), and are reported by physicians of other units (P = 0.05). UP-patients have a longer hospital admission (P = 0.032), a higher hospital death rate (P = 0.025), and are less frequently discharged home (P = 0.031). A significant decrease in intensity of ESAS items was observed in both groups, with no differences in symptom burden either at admission and time for discharge. At discharge, opioid doses are higher in UP-patients. An APCU may admit UP-patients at any stage of disease, providing effective treatment outcomes, as reported with P-patients. This study suggests that patients referred from other settings or hospitals may provide specialist advice and rapid symptom control. Although symptom burden is similar, these patients have longer hospital admission, higher hospital death rate, and are less frequently discharged home, suggesting the need for more complex treatments. Such units in a comprehensive cancer center might improve symptom control and pose as referral centers for non-cancer hospitals, emergency departments, or the territory.

What determines duration of palliative care before death for patients with advanced disease? A retrospective cohort study of community and hospital palliative care provision in a large UK city

OBJECTIVE

For patients with advanced cancer, several randomised controlled trials have shown that access to palliative care at least 6 months before death can improve symptoms, reduce unplanned hospital admissions, minimise aggressive cancer treatments and enable patients to make choices about their end-of-life care, including exercising the choice to die at home. This study determines in a UK population the duration of palliative care before death and explores influencing factors.

DESIGN

This retrospective cohort study analysed referrals to three specialist palliative care services; a hospital-based inpatient palliative care team, and two community-based services (hospices). For each patient referred to any of the above services we identified the date of first referral to that team and calculated the median interval between first referral and death. We also calculated how referral time varied by age, sex, diagnosis and type of palliative care service.

PARTICIPANTS

4650 patients referred to specialist palliative care services in Leeds UK between April 2012 and March 2014.

RESULTS

Median age of the sample was 75 years. 3903 (84.0%) patients had a diagnosis of cancer. Age, diagnosis and place of referral were significant predictors of duration of palliative care before death. Age was independently associated (J=2 672 078, z=-392046.14, r=0.01) with duration of palliative care regardless of diagnosis. Patients over 75 years have 29 fewer days of palliative care than patients under 50. Patients with non-cancer diagnoses have 13 fewer days of palliative care than patients with cancer. Additionally, patients referred to hospital palliative care receive 24.5 fewer days palliative care than those referred to community palliative care services.

CONCLUSIONS

The current timing of referral to palliative care may limit the benefits to patients in terms of improvements in end-of-life care, particularly for older patients and patients with conditions other than cancer.

The Palliative-Supportive Care Unit in a Comprehensive Cancer Center as Crossroad for Patients' Oncological Pathway

Aim

The aim of this study was to assess how an admission to an acute palliative-supportive care unit (APSCU), may influence the therapeutic trajectory of advanced cancer patients.

Methods

A consecutive sample of advanced cancer patients admitted to APCU was assessed. The following parameters were collected: patients demographics, including age, gender, primary diagnosis, marital status, and educational level, performance status and reasons for and kind of admission, data about care-givers, recent anticancer treatments, being on/off treatment or uncertain, the previous care setting, who proposed the admission to APSCU. Physical and psychological symptoms were evaluated at admission and at time of discharge. The use of opioids was also recorded. Hospital staying was also recorded. At time of discharge the parameters were recorded and a follow-up was performed one month after discharge.

Results

314 consecutive patients admitted to the APSCU were surveyed. Pain was the most frequent reason for admission. Changes of ESAS were highly significant, as well as the use of opioids and breakthrough pain medications (p <0.0005). A significant decrease of the number of “on therapy” patients was reported, and concomitantly a significant number of “off-therapy” patients increased. At one month follow-up, 38.9% patients were at home, 19.7% patients were receiving palliative home care, and 1.6% patients were in hospice. 68.5% of patients were still living.

Conclusion

Data of this study suggest that the APSCU may have a relevant role for managing the therapeutic trajectory of advanced cancer patients, limiting the risk of futile and aggressive treatment while providing an appropriate care setting.

Update on Prevalence of Pain in Patients With Cancer: Systematic Review and Meta-Analysis

CONTEXT

Cancer pain has a severe impact on quality of life and is associated with numerous psychosocial responses. Recent studies suggest that treatment of cancer pain has improved during the last decade.

OBJECTIVES

The aim of this review was to examine the present status of pain prevalence and pain severity in patients with cancer.

METHODS

A systematic search of the literature published between September 2005 and January 2014 was performed using the databases PubMed, Medline, Embase, CINAHL, and Cochrane. Articles in English or Dutch that reported on the prevalence of cancer pain in an adult population were included. Titles and abstracts were screened by two authors independently, after which full texts were evaluated and assessed on methodological quality. Study details and pain characteristics were extracted from the articles with adequate study quality. Prevalence rates were pooled with meta-analysis; meta-regression was performed to explore determinants of pain prevalence.

RESULTS

Of 4117 titles, 122 studies were selected for the meta-analyses on pain (117 studies, n = 63,533) and pain severity (52 studies, n = 32,261). Pain prevalence rates were 39.3% after curative treatment; 55.0% during anticancer treatment; and 66.4% in advanced, metastatic, or terminal disease. Moderate to severe pain (numerical rating scale score ≥5) was reported by 38.0% of all patients.

CONCLUSION

Despite increased attention on assessment and management, pain continues to be a prevalent symptom in patients with cancer. In the upcoming decade, we need to overcome barriers toward effective pain treatment and develop and implement interventions to optimally manage pain in patients with cancer.

Age differences in the last week of life in advanced cancer patients followed at home

A retrospective analysis of a consecutive sample of patients admitted to a home care program was performed. Data were recorded in the last week through a backward analysis from the day before death as follows: 1 week before dying (-1W), 3 days before death (-3D), and the day before dying (-1D). Data to be collected included the Edmonton Symptom Assessment System (ESAS), background pain intensity, the prevalence of breakthrough pain, the use of opioids in the last week, and the need for palliative sedation, with indications, duration, and drugs used. Patients were distributed according to the following age ranges: adults (<65 years, A) and aged (≥65 years, O). Of the latter group, three subgroups were assessed: old (65-74 years, O1), very old (75-84 years, O2), and the oldest (≥85 years, O3). Four hundred eleven patients were assessed. At -W1, no statistical differences in intensity of ESAS items ≥4 among the age subgroups were found. For ESAS values at -1W, -3D, and -1D, no statistical differences were found unless for anorexia at -1W (p = 0.000) (more likely), depression at -3D (p = 0.000) (less likely), depression (p = 0.000), and dyspnea (p = 0.01) (less likely) at -1D in the oldest group (O3). No differences in pain intensity among the groups were found (p = 0.54). Opioid doses increased in time and were significantly lower in older patients (p = 0.000). The subcutaneous route was more frequently used at -3D and -1D in older patients. No differences in opioid switching were found among the groups (p = 0.56). Adult patients required more often palliative sedation (p = 0.003). Older patients have problems relatively similar to adult patients in the last week of life, unless for some symptoms. Older patients had also a lower opioid consumption, a more frequent use of the subcutaneous route, and a lower need for palliative sedation.

Endogenous opiates and behavior: 2013

This paper is the thirty-sixth consecutive installment of the annual review of research concerning the endogenous opioid system. It summarizes papers published during 2013 that studied the behavioral effects of molecular, pharmacological and genetic manipulation of opioid peptides, opioid receptors, opioid agonists and opioid antagonists. The particular topics that continue to be covered include the molecular-biochemical effects and neurochemical localization studies of endogenous opioids and their receptors related to behavior, and the roles of these opioid peptides and receptors in pain and analgesia; stress and social status; tolerance and dependence; learning and memory; eating and drinking; alcohol and drugs of abuse; sexual activity and hormones, pregnancy, development and endocrinology; mental illness and mood; seizures and neurologic disorders; electrical-related activity and neurophysiology; general activity and locomotion; gastrointestinal, renal and hepatic functions; cardiovascular responses; respiration and thermoregulation; and immunological responses.

Pain: a descriptive study in patients with cancer

Ninety percent of patients with advanced cancer are reported to experience pain at some time during the course of their illness. This pain usually is improperly evaluated because it varies by patient and is difficult to control. Pain often cannot be conceptualized because of the individual nature of patient experience; however, patterns of pain occur in those suffering from similar conditions. This secondary analysis was conducted to examine the characteristics of pain in individuals with advanced cancer. The sample consisted of 717 patients with cancer who were receiving hospice home care in the southeastern United States. An understanding of the total pain experience, including type of pain and pain location, is important for addressing pain in patients with cancer in hospice care. More effective strategies are needed for pain management in this patient population. In addition, steps need to be taken to ensure that hospice care is understood by and made available to minorities.

Prevalence of breakthrough cancer pain: a systematic review and a pooled analysis of published literature

CONTEXT

Despite the large body of literature on breakthrough cancer pain (BTcP), an accurate estimate of BTcP prevalence is still not available.

OBJECTIVES

To provide an estimate of BTcP prevalence and investigate the association between different prevalence rates and possible determinants.

METHODS

We conducted MEDLINE and EMBASE searches for studies published from 1990 to 2012 reporting data on BTcP prevalence in adult cancer populations. Pooled prevalence rates from observational studies with an acceptable methodological quality were computed. The association between BTcP prevalence and possible predictors was investigated using subgroup analyses and meta-regression.

RESULTS

Twenty-seven observational studies were identified. When quality criteria were applied, only 19 studies were included in the pooled analysis. The overall pooled prevalence was 59.2%, with high heterogeneity. The lowest prevalence rates were detected in studies conducted in outpatient clinics (39.9%), and the highest prevalence was reported in studies conducted in hospice (80.5%). The association between BTcP prevalence and other determinants such as publication year, age, gender, metastatic disease prevalence, or baseline pain intensity did not reach statistical significance.

CONCLUSION

In the context of a large between-studies heterogeneity, more than one in two patients with cancer pain also experiences BTcP, with some variability according to clinical and organizational variables.

Opioid use and effectiveness of its prescription at discharge in an acute pain relief and palliative care unit

The aim of this study was to present how opioids are used in an acute pain relief and palliative care unit (APRPCU), where many patients with difficult pain conditions are admitted from GPs, home palliative care programs, oncology departments, other hospitals or emergency units, and other regional places. From a consecutive sample of cancer patients admitted to an APRPCU for a period of 6 months, patients who had been administered opioids were included in this survey. Basic information was collected as well as opioid therapy prescribed at admission and, subsequently, during admission and at time of discharge. Patients were discharged once stabilization of pain and symptoms were obtained and the treatment was considered to be optimized. One week after being discharged, patients or relatives were contacted by phone to gather information about the availability of opioids at dosages prescribed at time of discharge. One hundred eighty six of 231 patients were specifically admitted for uncontrolled pain, with a mean pain intensity of 6.8 (SD 2.5). The mean dose of oral morphine equivalents in patients receiving opioids before admission was 45 mg/day (range 10-500 mg). One hundred seventy five patients (75.7 %) were prescribed around the clock opioids at admission. About one third of patients changed treatment (opioid or route). Forty two of 175 (24 %), 27/58 (46.5 %), 10/22 (45.4 %), and 2/4 (50 %) patients were receiving more than 200 mg of oral morphine equivalents, as maximum dose of the first, second, third, and fourth opioid prescriptions, respectively. The pattern of opioids changed, with the highest doses administered with subsequent line options. The mean final dose of opioids, expressed as oral morphine equivalents, for all patients was 318 mg/day (SD 798), that is more than six times the doses of pre-admission opioid doses. One hundred eighty six patients (80.5 %) were prescribed a breakthrough cancer pain (BTcP) medication at admission.
