Knowledge and utilization of palliative radiotherapy by pediatric oncologists

Background and Purpose

Palliative radiotherapy (prt) is a routine part of oncology care in adult patients, but it is used much less frequently among children with incurable cancer. We surveyed Canadian pediatric oncologists to learn about their knowledge and use of prt and to identify potential barriers to referral.

Methods

A 13-item questionnaire assessing prt knowledge and utilization was sent to 80 Canadian pediatric oncologists.

Results

The survey completion rate was 80%, with most respondents being providers of palliative care for children and making referrals for prt. Although 62% had received training in radiation oncology, only 28% had received formal palliative care training. Respondents with palliative care training were found to be significantly more knowledgeable about prt and were more likely to refer children for prt (p < 0.01). Only 59% of respondents thought that they had adequate knowledge about the indications for prt. A positive correlation was found between knowledge about the indications for prt and referral for treatment (p < 0.01). Among survey respondents, 51% believed that prt was underutilized, and the perceived barriers to prt referral included patient or family reluctance, distance to the cancer centre, belief that prt has little impact on quality of life, and concerns about toxicity.

Conclusions

Palliative radiotherapy is considered to be underutilized among children. This situation appears to be related, in part, to inadequate knowledge and training among pediatric oncologists, suggesting that more emphasis needs to be placed on pediatric palliative care education.     

Regional Variation in Identified Cancer Care Needs of Early‐Career Oncologists in China,India, and Pakistan

Background.

Cancer incidence and mortality is increasing in the developing world. Inequities between low-, middle-, and high-income countries affect disease burden and the infrastructure needs in response to cancer. We surveyed early-career oncologists attending workshops in clinical research in three countries with emerging economies about their perception of the evolving cancer burden.

Methods.

A cross-sectional survey questionnaire was distributed at clinical trial concept development workshops held in Beijing, Lahore, Karachi, and Mumbai at major hospitals to acquire information regarding home-country health conditions and needs.

Results.

A total of 100 respondents participated in the workshops held at major hospitals in the region (India = 29, China = 25, Pakistan = 42, and other = 4). Expected consensus on many issues (e.g., emergence of cancer as a significant health issue) was balanced with significant variation in priorities, opportunities, and challenges. Chinese respondents prioritized improvements in cancer-specific care and palliative care, Indian respondents favored improved cancer detection and advancing research in cancer care, and Pakistani respondents prioritized awareness of cancer and improvements in disease detection and cancer care research. For all, the most frequently cited opportunity was help in improving professional cancer education and training.

Conclusion.

Predominantly early-career oncologists attending clinical research workshops (in China, India, and Pakistan) identified needs for increasing clinical cancer research, professional education, and public awareness of cancer. Decision makers supporting efforts to reduce the burden of cancer worldwide will need to factor the specific needs and aspirations of health care providers in their country in prioritizing health policies and budgets.     

Effects of opioids on immunologic parameters that are relevant to anti-tumour immune potential in patients with cancer: a systematic literature review

Background:

The immune system has a central role in controlling cancer, and factors that influence protective antitumour immunity could therefore have a significant impact on the course of malignant disease. Opioids are essential for the management of cancer pain, and preclinical studies indicate that opioids have the potential to influence these tumour immune surveillance mechanisms. The aim of this systematic literature review is to evaluate the clinical effects of opioids on the immune system of patients with cancer.

Methods:

A systematic search of Ovid MEDLINE (PubMed) and Embase, Cochrane database and Web of Knowledge for clinical studies, which evaluated the effects of opioids on the immune system in patients with cancer, was performed.

Results:

Five human studies, which have assessed the effects of opioids on the immune system in patients with cancer, were identified. Although all of these evaluated the effect of morphine on immunologic end points in patients with cancer, none measured the clinical effects.

Conclusions:

Evidence from preclinical, healthy volunteer and surgical models suggests that different opioids variably influence protective anti-tumour immunity; however, actual data derived from cancer populations are inconclusive and definitive recommendations cannot be made. Appropriately designed and powered studies assessing clinical outcomes of opioid use in people with cancer are therefore required to inform oncologists and others involved in cancer care about the rational use of opioids in this patient group.     

The Opioid Rotation Ratio of Hydrocodone to Strong Opioids in Cancer Patients

Purpose.

Cancer pain management guidelines recommend initial treatment with intermediate-strength analgesics such as hydrocodone and subsequent escalation to stronger opioids such as morphine. There are no published studies on the process of opioid rotation (OR) from hydrocodone to strong opioids in cancer patients. Our aim was to determine the opioid rotation ratio (ORR) of hydrocodone to morphine equivalent daily dose (MEDD) in cancer outpatients.

Patients and Methods.

We reviewed the records of consecutive patient visits at our supportive care center in 2011–2012 for OR from hydrocodone to stronger opioids. Data regarding demographics, Edmonton Symptom Assessment Scale (ESAS), and MEDD were collected from patients who returned for follow-up within 6 weeks. Linear regression analysis was used to estimate the ORR between hydrocodone and MEDD. Successful OR was defined as 2-point or 30% reduction in the pain score and continuation of the new opioid at follow-up.

Results.

Overall, 170 patients underwent OR from hydrocodone to stronger opioid. The median age was 59 years, and 81% had advanced cancer. The median time between OR and follow-up was 21 days. We found 53% had a successful OR with significant improvement in the ESAS pain and symptom distress scores. In 100 patients with complete OR and no worsening of pain at follow-up, the median ORR from hydrocodone to MEDD was 1.5 (quintiles 1–3: 0.9–2). The ORR was associated with hydrocodone dose (r = −.52; p < .0001) and was lower in patients receiving ≥40 mg of hydrocodone per day (p < .0001). The median ORR of hydrocodone to morphine was 1.5 (n = 44) and hydrocodone to oxycodone was 0.9 (n = 24).

Conclusion.

The median ORR from hydrocodone to MEDD was 1.5 and varied according to hydrocodone dose.     

Frequency,Predictors, and Medical Record Documentation of Chemical Coping Among Advanced Cancer Patients

Background.

In this prospective study, we determined the frequency of opioid-related chemical coping among advanced cancer patients, as diagnosed by palliative medicine specialists. We also determined predictors for chemical coping and the concordance between the physician’s diagnosis and documentation in the medical records.

Patients and Methods.

Palliative medicine specialists evaluated and diagnosed consecutive patients seen for chemical coping. The proportion of patients identified as chemically coping was compared with the proportion documented in the medical records. Demographic data; cancer diagnosis; history of smoking; substance abuse; psychiatric disease; morphine equivalent daily dosage; Cut-down, Annoyed, Guilty, and Eye-opener (CAGE) questionnaire scores; and Edmonton Symptom Assessment System scores were also collected.

Results.

A total of 432 patients were evaluated. Overall, 76 patients (18%; 95% confidence interval [CI]: 14%–21%) were diagnosed as chemically coping. Documentation of chemical coping in the medical records was reported for only 15 patients (4%; 95% CI: 2%–6%). CAGE positivity (odds ratio [OR]: 2.89), younger age (OR: 0.97 per year), better performance status (OR: 0.68 per point), pain (OR: 1.20 per point), and well-being (OR: 1.28 per point) were found to be significant predictors of chemical coping by protocol definition. After recursive partitioning, 21 of 50 patients (42%) who were CAGE positive and had an Eastern Cooperative Oncology Group performance status ≤2 were diagnosed as chemically coping.

Conclusion.

Approximately 18% of palliative care patients seen were diagnosed as chemically coping by palliative medicine specialists. The frequency of documentation in the medical records was significantly lower. Better and safer ways for physicians to assess and report chemical coping are needed.

Implications for Practice:

Cancer pain is a multidimensional symptom for which opioids are the mainstay of treatment. However, opioids can have a double effect resulting in drug-seeking behaviors. Chemical coping occurs when a patient uses opioids in a nonprescribed way to cope with various stressful events. This can lead to misuse of opioids and complications including neurotoxicities, respiratory depression, and death. Proper diagnosis and documentation is needed to ensure proper management of pain and to avoid unnecessary harm. The findings of this study suggest that ∼18% of advanced cancer patients seen by a palliative care service were diagnosed as chemical coping, but only 4% were documented in the medical records.     

Frequency,Outcome, and Predictors of Success Within 6 Weeks of an Opioid Rotation Among Outpatients with Cancer Receiving Strong Opioids

Background.

Opioid rotation is used to treat uncontrolled pain and/or opioid-related adverse effects. Our aim was to determine the frequency, indications, outcomes, and predictors of successful opioid rotation in outpatients with cancer.

Methods.

Medical records of consecutive outpatients with cancer who received strong opioids and returned for follow-up visit within ≤6 weeks to our supportive care center from January to December 2008 were reviewed. Data on patient characteristics, symptoms, opioid use, indications for opioid rotation, outcomes, and morphine equivalent daily dose were collected. Successful opioid rotation was defined as a two-point or 30% reduction in the symptom score or the resolution of opioid-induced neurotoxicity and continuation of the new opioid at follow-up.

Results.

Opioid rotation was performed in 120 of 385 patients (31%). The median patient age was 55 years. There were 6/120 patients with missing data. Of the 114 evaluable patients, 68 (60%) were men, 81 (71%) were white, 27 (24%) had gastrointestinal cancer, and 90 (80%) had advanced-stage disease. The median Eastern Cooperative Oncology Group score was 1 (interquartile range: 1–2) and the median time between opioid rotation and follow-up was 14 days (interquartile range: 7–21 days). The most common indications for opioid rotation were uncontrolled pain (95/114; 83%) and opioid-induced neurotoxicity (13/114; 12%). A total of 35 patients (31%) had partial opioid rotation. The median improvements in pain and symptom distress score were −2 (interquartile range: −4 to 0; p < .001) and −5 (interquartile range: −14 to 7; p = .004), respectively. The morphine equivalent daily dose did not change significantly after opioid rotation (p = .156). A total of 65% of patients (74/114) had successful opioid rotation. There were no clinically significant independent predictors for successful opioid rotation.

Conclusion.

Opioid rotation was conducted in 31% of outpatients with cancer, with a 65% success rate. The most frequent reason for opioid rotation was uncontrolled pain. There were no independent predictors for successful opioid rotation.     

Association between a name change from palliative to supportive care and the timing of patient referrals at a comprehensive cancer center

Purpose.

Palliative care consultation services are now available in the majority of cancer centers, yet most referrals to palliative care occur late. We previously found that the term “palliative care” was perceived by oncology professionals as a barrier to early patient referral. We aimed to determine whether a service name change to supportive care was associated with earlier referrals.

Patients and Methods.

Records of 4,701 consecutive patients with a first palliative care consultation before (January 2006 to August 2007) and after (January 2008 to August 2009) the name change were analyzed, including demographics and dates of first registration to hospital, advanced cancer diagnosis, palliative care consultation, and death. One-sample proportions tests, median tests, χ² tests, and log-rank tests were used to identify group differences.

Results.

The median age was 59 years, 50% were male, and 90% had solid tumors. After the name change, we found: (a) a 41% greater number of palliative care consultations (1,950 versus 2,751 patients; p < .001), mainly as a result of a rise in inpatient referrals (733 versus 1,451 patients; p < .001), and (b) in the outpatient setting, a shorter duration from hospital registration to palliative care consultation (median, 9.2 months versus 13.2 months; hazard ratio [HR], 0.85; p < .001) and from advanced cancer diagnosis to palliative care consultation (5.2 months versus 6.9 months; HR, 0.82; p < .001), and a longer overall survival duration from palliative care consultation (median 6.2 months versus 4.7 months; HR, 1.21; p < .001).

Conclusion.

The name change to supportive care was associated with more inpatient referrals and earlier referrals in the outpatient setting. The outpatient setting facilitates earlier access to supportive/palliative care and should be established in more centers.     

Octreotide treatment of patients with hepatocellular carcinoma - a retrospective single centre controlled study

Background

Studies of treatment with octreotide of patients with hepatocellular carcinoma (HCC) gave conflicting results. We analyzed retrospectively the survival of our patients treated with octreotide monotherapy and compared it to stage-matched patients who received either TACE, multimodal therapy or palliative care.

Methods

95 patients seen at the department of Gastroenterology and Hepatology, Medical University of Vienna with HCC in BCLC stage A or B, who received either TACE, multimodal therapy, long-acting octreotide or palliative care were reviewed for this retrospective study.

Results

Survival rates of patients with BCLC stage B and any "active" treatment (long-acting octreotide, TACE or multimodal therapy) were significantly higher (22.4, 22.0, 35.5 months) compared to patients who received palliative care only (2.9 months). Survival rates of patients with BCLC stage A and "active" treatment (31.4, 37.3, 40.2 months) compared to patients who received only palliative care (15.1 months) did not show statistically significant differences. Octreotide monotherapy showed a similar outcome compared to patients who received TACE or multimodal therapy.

Conclusion

Survival under octreotide treatment was not different compared to TACE or multimodal therapy and might be a therapeutic option for patients with HCC.     

A preliminary report on adjuvant analgesic efficacy of HANS in opioid tolerant patients with cancer pain

Objective： To observe the adjuvant analgesic efficacy of Han＇s Acupoint Nerve Stimulator （HANS） in opioid tolerant patients with cancer pain. Methods： A prospective non-controlled study was conducted. Opioid tolerant patients with cancer pain were enrolled and treated with both routinely analgesics and adjuvant HANS （2/100 Hz for 30 min/d, 5 d on and 2 d off for two weeks）. Cancer pain, quality of life （QOL）, anxiety and depression were assessed before enrollment and on d 8 and d 15 with the BPI-C, EORTC QLQ-C30, and self-rating anxiety scale （SAS）/ self-rating depression scale （SDS）, respectively; the therapeutic frequency of breakthrough pain （BP） and daily opioid dose were also recorded. Results： Totally 47 patients meeting the inclusion criteria participated in this study; 43 patients completed the two-week treatment and assessment. The mean scores of patient＇s ＂worst＂ and ＂least＂ pain intensity assessed with BPI-C decreased significantly on d 8 and d 15; the therapeutic frequency of BP also significantly decreased; but the average daily dose of opioids did not change significantly. For the nine symptoms in EORTC QLQ-C30 assessment, the mean scores of pain, fatigue, constipation and insomnia were significantly lower on d 8 and d 15 compared with baseline; the mean scores of the overall health status, nausea/vomiting and the incidence rates of both anxiety and depression also decreased significantly on d 15. Conclusions： To opioid tolerant patients with cancer pain, adjuvant treatment with HANS could improve pain release and patients＇ QOL by decreasing the severity of pain, fatigue, constipation, insomnia and other concomitant symptoms; it could also decrease the incidence rates of anxiety and depression.     

Pain in underserved community-dwelling Chinese American cancer patients: demographic and medical correlates

Background.

Little is known about cancer pain in Chinese Americans. The objective of this study was to describe the epidemiology of pain in this population. This information is needed to identify and address unmet clinical needs for culturally relevant interventions targeting pain and its consequences.

Methods.

A consecutive sample of underserved ethnic Chinese patients in a large community-based oncology practice was screened for persistent or frequent pain. Those patients with pain completed translated instruments assessing demographics, linguistic acculturation, disease-related characteristics, and pain-related characteristics.

Results.

Of 312 patients screened, 178 (57.1%) reported frequent or persistent pain, 175 were eligible, and 170 participated. Most participants (85.9%) were born in China and 84.7% overall spoke Cantonese only. The most common cancers were gastrointestinal (28.2%), lung (21.8%), breast (20.6%), head and neck (12.9%), and genitourinary (4.7%); 43.5% had metastatic disease. The mean worst pain severity on a 0–10 numeric scale was 4.7 (standard deviation, 2.4), with 28.2% of patients rating their worst pain at ≥7 of 10. Although 37.6% used opioids and 47.1% used nonopioids, 45.8% reported “little” or “no” pain relief from medications. Complementary or alternative medicine therapies for cancer pain were used by 35.8%. In multiple regression analyses, worst pain was positively associated with acculturation to the English language and opioid therapy, and pain-related distress was positively associated with opioid therapy.

Conclusion.

Pain is prevalent among community-dwelling, ethnic Chinese American cancer patients. Additional studies are needed to confirm these results and investigate the finding that higher linguistic acculturation is associated with reports of more intense pain.     

Surprise Questions for Survival Prediction in Patients With Advanced Cancer: A Multicenter Prospective Cohort Study

Background.

Predicting the short-term survival in cancer patients is an important issue for patients, family, and oncologists. Although the prognostic accuracy of the surprise question has value in 1-year mortality for cancer patients, the prognostic value for short-term survival has not been formally assessed. The primary aim of the present study was to assess the prognostic value of the surprise question for 7-day and 30-day survival in patients with advanced cancer.

Patients and Methods.

The present multicenter prospective cohort study was conducted in Japan from September 2012 through April 2014, involving 16 palliative care units, 19 hospital-based palliative care teams, and 23 home-based palliative care services.

Results.

We recruited 2,425 patients and included 2,361 for analysis: 912 from hospital-based palliative care teams, 895 from hospital palliative care units, and 554 from home-based palliative care services. The sensitivity, specificity, positive predictive value, and negative predictive value of the 7-day survival surprise question were 84.7% (95% confidence interval [CI], 80.7%–88.0%), 68.0% (95% CI, 67.3%–68.5%), 30.3% (95% CI, 28.9%–31.5%), and 96.4% (95% CI, 95.5%–97.2%), respectively. The sensitivity, specificity, positive predictive value, and negative predictive value for the 30-day surprise question were 95.6% (95% CI, 94.4%–96.6%), 37.0% (95% CI, 35.9%–37.9%), 57.6% (95% CI, 56.8%–58.2%), and 90.4% (95% CI, 87.7%–92.6%), respectively.

Conclusion.

Surprise questions are useful for screening patients for short survival. However, the high false-positive rates do not allow clinicians to provide definitive prognosis prediction.

Implications for Practice:

The findings of this study indicate that clinicians can screen patients for 7- or 30-day survival using surprise questions with 90% or more sensitivity. Clinicians cannot provide accurate prognosis estimation, and all patients will not always die within the defined periods. The screened patients can be regarded as the subjects to be prepared for approaching death, and proactive discussion would be useful for such patients.     

Palliative Care in the Caribbean Through the Lens of Women with Breast Cancer: Challenges and Opportunities

Background

Across the Caribbean, too many women are presenting with advanced breast cancer and dying with little or no access to palliative care. No comprehensive assessment of current capacity to deliver palliative care in the region exists, largely due to limited data. We assess the challenges in delivering palliative care for breast cancer patients in the Caribbean, highlighting the needs and experiences of low-income women through emblematic patient narratives.

Recent Findings

There is an urgent need to improve access to palliative care and pain relief throughout the region. Challenges include insufficient healthcare infrastructures to support cancer care, tremendous unmet need for palliative care, pervasive opiophobia resulting in limited access to opioids for pain relief, patients’ reluctance to engage with clinical care, and the widespread use of complementary and alternative medicines prior to the acceptance of conventional care.

Summary

There is an urgent need to improve access to palliative care and pain relief for cancer patients in the Caribbean. Strong regional collaboration, provider and patient education, improved access to opioids, and innovative models for palliative care that reflect the culture and resources available in the region have the potential to measurably improve palliative care delivery.

     

Cancer symptom awareness and barriers to symptomatic presentation in England—are we clear on cancer?

Background:

Low cancer awareness may contribute to delayed diagnosis and poor cancer survival. We aimed to quantify socio-demographic differences in cancer symptom awareness and barriers to symptomatic presentation in the English population.

Methods:

Using a uniquely large data set (n=49 270), we examined the association of cancer symptom awareness and barriers to presentation with age, gender, marital status and socio-economic position (SEP), using logistic regression models to control for confounders.

Results:

The youngest and oldest, the single and participants with the lowest SEP recognised the fewest cancer symptoms, and reported most barriers to presentation. Recognition of nine common cancer symptoms was significantly lower, and embarrassment, fear and difficulties in arranging transport to the doctor''s surgery were significantly more common in participants living in the most deprived areas than in the most affluent areas. Women were significantly more likely than men to both recognise common cancer symptoms and to report barriers. Women were much more likely compared with men to report that fear would put them off from going to the doctor.

Conclusions:

Large and robust socio-demographic differences in recognition of some cancer symptoms, and perception of some barriers to presentation, highlight the need for targeted campaigns to encourage early presentation and improve cancer outcomes.     

Characterizing distress, the 6th vital sign, in an oncology pain clinic

Context

The delineation of populations of cancer patients with complex symptoms can inform the planning and delivery of supportive care services.

Objectives

We explored the physical, psychosocial, and practical concerns experienced by patients attending an ambulatory oncology symptom control clinic.

Methods

Patients attending a Pain Clinic at a large tertiary cancer centre were invited to complete screening measures assessing distress, pain, fatigue, anxiety, depression, and practical and psychosocial problems. A matched sample of patients who did not attend the Pain Clinic were selected as a comparison group.

Results

Of all eligible Pain Clinic patients, 46 (77%) completed the measures; so did 46 comparison group patients. The percentages of patients reporting distress (78.3%), pain (93.5%), and fatigue (93.5%) were higher among Pain Clinic patients than among the comparison patients. A higher percentage of Pain Clinic patients also reported multiple, severe, concurrent symptoms: 87% scored 7 or higher in at least one of the pain, fatigue, or distress scales, and 30.4% of the patients scored 7 or higher on all three. The most common problem areas were feeling a burden to others, trouble talking with friends and family, spirituality, and sleep difficulties.

Conclusions

Higher levels of multiple, concurrent symptoms and psychosocial problems were found in Pain Clinic patients than in a group of patients who did not attend the Pain Clinic. Routine screening and triaging of cancer patients using a comprehensive and standardized panel of questions can facilitate symptom assessment and management, and can inform program planning.     

Does the ‘Liverpool Care Pathway' facilitate an improvement in quality of care for dying cancer patients?

Background:

The Liverpool Care Pathway for the Dying Patient (LCP) aims to transfer hospice principles of care for dying patients to other health-care sectors. This post-bereavement survey explored the LCP''s effectiveness in improving quality of care for cancer patients.

Methods:

Postal self-completion questionnaires were sent to 778 next-of-kin to consecutive deceased patients who had died an ‘expected'' cancer death in a hospice and acute tertiary hospital.

Results:

Following exclusions (n=53), 255 of the 725 next-of-kin agreed to participate (35.2% response rate). Overall hospice participants reported the best quality of care, and hospital participants, for whom care was not supported by the LCP, reported the worst quality of care. Multivariate analysis showed the hospice was an independent predictor for patients being treated with dignity (OR 8.46) and receiving adequate family support (OR 7.18) (P<0.0001). Care supported by the LCP and the hospital specialist palliative care team were both associated with good family support, but neither was an independent predictor.

Conclusions:

From the bereaved relatives'' perspective, within the hospital, the LCP is effective in improving specific aspects of care, such as symptom control for dying patients. Further improvement is required, however, to attain the hospice standard of care.     

Age and Gender Moderate the Impact of Early Palliative Care in Metastatic Non‐Small Cell Lung Cancer

Background.

Studies demonstrate that early palliative care (EPC) improves advanced cancer patients’ quality of life (QOL) and mood. However, it remains unclear whether the role of palliative care differs based upon patients’ demographic characteristics. We explored whether age and gender moderate the improvements in QOL and mood seen with EPC.

Methods.

We performed a secondary analysis of data from a randomized controlled trial of patients with metastatic non-small cell lung cancer. Patients received either EPC integrated with oncology care or oncology care alone. We assessed the degree to which QOL (Trial Outcome Index [TOI]) and mood (Hospital Anxiety and Depression Scale [HADS] and Patient Health Questionnaire 9 [PHQ-9]) outcomes at week 12 varied by patient age (<65) and gender. The week 12 data of 107 patients are included in this analysis.

Results.

At 12 weeks, younger patients receiving EPC reported better QOL (TOI mean = 62.04 vs. 49.43, p = .001) and lower rates of depression (HADS–Depression = 4.0% vs. 52.4%, p < .001; PHQ-9 = 0.0% vs. 28.6%, p = .006) than younger patients receiving oncology care alone. Males receiving EPC reported better QOL (TOI mean = 58.81 vs. 48.30, p = .001) and lower rates of depression (HADS–Depression = 18.5% vs. 60.9%, p = .002; PHQ-9 = 3.8% vs. 34.8%, p = .008) than males receiving oncology care alone. At 12 weeks, QOL and mood did not differ between study groups for females and older patients.

Conclusion.

Males and younger patients who received EPC had better QOL and mood than those who received oncology care alone. However, these outcomes did not differ significantly between treatment groups for females or older patients.

Implications for Practice:

This study found that early palliative care improves patients’ quality of life and mood differentially based on their age and gender. Specifically, males and younger patients receiving early palliative care experienced better quality of life and mood than those receiving oncology care alone. Conversely, females and older patients did not experience this treatment effect. Thus, palliative care interventions may need to be tailored to patients’ age- and gender-specific care needs. Studying how patients’ demographic characteristics affect their experience with palliative care will enable the development of interventions targeted to the distinct supportive care needs of patients with cancer.     

Establishing a multicentre clinical research network: lessons learned

Background

Within many health care disciplines, research networks have emerged to connect researchers who are physically separated, to facilitate sharing of expertise and resources, and to exchange valuable skills. A multicentre research network committed to studying difficult cancer pain problems was launched in 2004 as part of a Canadian initiative to increase palliative and end-of-life care research capacity. Funding was received for 5 years to support network activities.

Methods

Mid-way through the 5-year granting period, an external review panel provided a formal mid-grant evaluation. Concurrently, an internal evaluation of the network by survey of its members was conducted. Based on feedback from both evaluations and on a review of the literature, we identified several components believed to be relevant to the development of a successful clinical cancer research network.

Results

These common elements of successful clinical cancer research networks were identified: shared vision, formal governance policies and terms of reference, infrastructure support, regular and effective communication, an accountability framework, a succession planning strategy to address membership change over time, multiple strategies to engage network members, regular review of goals and timelines, and a balance between structure and creativity.

Conclusions

In establishing and conducting a multi-year, multicentre clinical cancer research network, network members were led to reflect on the factors that contributed most to the achievement of network goals. Several specific factors were identified that seemed to be highly relevant in promoting success. These observations are presented to foster further discussion on the successful design and operation of research networks.     

How Well Do Medical Oncologists Manage Chronic Cancer Pain? A National Survey

Background.

Cancer pain is usually managed by oncologists, occasionally with input from specialists in hospice and palliative medicine (PLM) or pain medicine (PMD). We evaluated the knowledge of cancer pain management in these three specialty groups.

Methods.

Eight vignettes depicting challenging scenarios of patients with poorly controlled pain were developed; each had five or six treatment choices. Respondents indicated choices likely to be safe and efficacious as “true” and choices likely to be unsafe or inefficacious as “false.” Two questionnaires were created, each with four vignettes. Three anonymous mailings targeted geographically representative U.S. samples of 570 oncologists, 266 PMD specialists, and 280 PLM specialists, each randomly assigned one version of the questionnaire. Vignette scores were normalized to a 0–100 numeric rating scale (NRS); a score of 50 indicates that the number of correct choices equals the number of incorrect choices (consistent with guessing).

Results.

Overall response rate was 49% (oncologists, 39%; PMD specialists, 48%; and PLM specialists, 70%). Average vignette score ranges were 53.2–66.5, 45.6–65.6, and 50.8–72.0 for oncologists, PMD specialists, and PLM specialists, respectively. Oncologists scored lower than PLM specialists on both questionnaires and lower than PMD specialists on one. On a 0–10 NRS, oncologists rated their ability to manage pain highly (median 7, with an interquartile range [IQR] of 5–8). Lower ratings were assigned to pain-related training in medical school (median 3, with an IQR of 2–5) and residency/fellowship (median 5, with an IQR of 4–7). Oncologists older than 46–47 years rated their training lower than younger oncologists.

Conclusion.

These data suggest that oncologists and other medical specialists who manage cancer pain have knowledge deficiencies in cancer pain management. These gaps help clarify the need for pain management education.
