A Review of the Literature on the Pain Experience of Chinese Patients With Cancer

The Behavioral Adaptations and Barriers of Patients Employing Non-Pharmacological Strategies for Cancer Pain Management-A Qualitative Study

The use of non-pharmacological strategies to complement pharmacological approaches can enhance cancer pain management by promoting patient autonomy and increasing management effectiveness. This study aimed to explore the required behavioral adaptations and situational barriers that cancer patients encounter when utilizing non-pharmacological strategies to manage pain. We adopted an exploratory-descriptive qualitative research approach, purposive sampling, and semi-structured interview guidelines to conduct face-to-face interviews with 18 cancer patients experiencing moderate or severe levels of worst pain. Data were analyzed using inductive content analysis to explore patients' experiences. Five themes described the behavioral adaptations of patients using non-pharmacological strategies to deal with cancer pain: finding complementary therapies, utilizing assistive skills, adapting to assistive skills, diverting attention, and seeking help. Situational barriers faced by patients include being in the workplace or in a climate-affected environment. Behavioral adaptation is necessary for non-pharmacological strategies to coping with cancer pain. The behavioral skills can help the patients to overcome situational barriers to engagement with these strategies. Thus, health professionals are expected to help the patients acquire adequate behavioral adaptation and skills for self-pain management, and assess the effectiveness of the strategies.

Ethical Dilemma: Healthcare Surrogate Refusal of Opioid Administration

It is morally distressing when a healthcare provider sees patients with undertreated pain but is unable to provide adequate relief because of a surrogate's refusal of such treatment. This issue might occur when there is no clear advanced directive that represents patients' wishes for treatment, and can be further complicated when patients are of minority cultural backgrounds. This article presents a case where the surrogate of a Korean-American woman with severe somatic pain from metastatic pancreatic cancer requested only acetaminophen be given to control the patient's pain. The ethical issues associated with surrogate misconceptions on therapeutic use of opioids are reviewed. This case highlights the ethical dilemma of withholding opioid treatment in a patient with advanced cancer. We conclude that the obligation to treat pain should be understood beyond the authority of surrogate refusal, in favor of patient quality of life, when an advance directive is not in place.

Cancer pain management needs and perspectives of patients from Chinese backgrounds: a systematic review of the Chinese and English literature

Objective

More than half of all cancer patients experience unrelieved pain. Culture can significantly affect patients’ cancer pain-related beliefs and behaviors. Little is known about cultural impact on Chinese cancer patients’ pain management. The objective of this review was to describe pain management experiences of cancer patients from Chinese backgrounds and to identify barriers affecting their pain management.

Method

A systematic review was conducted adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies were included if they reported pain management experiences of adult cancer patients from Chinese backgrounds. Five databases were searched for peer-reviewed articles published in English or Chinese journals between1990 and 2015. The quality of included studies was assessed using Joanna Briggs Institution's appraisal tools.

Results

Of 3,904 identified records, 23 articles met criteria and provided primary data from 6,110 patients. Suboptimal analgesic use, delays in receiving treatment, reluctance to report pain, and/or poor adherence to prescribed analgesics contributed to the patients’ inadequate pain control. Patient-related barriers included fatalism, desire to be good, low pain control belief, pain endurance beliefs, and negative effect beliefs. Patients and family shared barriers about fear of addiction and concerns on analgesic side effects and disease progression. Health professional–related barriers were poor communication, ineffective management of pain, and analgesic side effects. Healthcare system–related barriers included limited access to analgesics and/or after hour pain services and lack of health insurance.

Significance of results

Chinese cancer patients’ misconceptions regarding pain and analgesics may present as the main barriers to optimal pain relief. Findings of this review may inform health interventions to improve cancer pain management outcomes for patients from Chinese backgrounds. Future studies on patients’ nonpharmacology intervention-related experiences are required to inform multidisciplinary and biopsychosocial approaches for culturally appropriate pain management.

Quality of Life in Community-Dwelling Chinese American Patients with Cancer Pain

Although pain can be a powerful influence on health-related quality of life (HRQL) in cancer populations, culturally-based beliefs and behaviors may directly impact HQRL or modify the association between pain and HQRL. Studies of well-defined ethnic groups may clarify these relationships and inform culturally competent clinical practices intended to reduce illness burden. We evaluated HRQL in 121 non-English-speaking Chinese immigrants with cancer pain using the Functional Assessment of Cancer Therapy-General (FACT-G) scale. Overall, 91.2 % were born in China and 86.0 % were Cantonese-speaking; 50.8 % had no formal education (mean age = 63.2 years; 68.6 % women). Although the mean FACT-G score did not differ from U.S. population norms, most subscale scores for Chinese immigrants were lower and the score for social/family well-being was higher (all p < 0.05). Higher educational level, caregiver presence, lower psychological distress, lower pain intensity and interference, and lower symptom distress were associated with better HRQL (all p < 0.05). These findings confirm the importance of diverse influences on HQRL in ethnic Chinese cancer patients with chronic pain and suggest that this group may be distinguished from the majority population by the extent to which social/family well-being is preserved. Future studies in the growing population of Chinese Americans with cancer are needed to evaluate various aspects of social/family well-being and determine whether they modify the association between pain and HRQL.

Which symptoms come first? Exploration of temporal relationships between cancer-related symptoms over an 18-month period

BACKGROUND

Anxiety, depression, insomnia, fatigue, and pain are frequently reported by cancer patients. These symptoms are highly interrelated. However, few prospective studies have documented the sequence with which symptoms occur during cancer care.

PURPOSE

This longitudinal study explored the temporal relationships between anxiety, depression, insomnia, fatigue, and pain over an 18-month period in a large population-based sample of nonmetastatic cancer patients (N = 828), using structural equation modeling.

METHODS

The patients completed a battery of self-report scales at baseline and 2, 6, 10, 14, and 18 months later.

RESULTS

The relationships between the same symptom at two consecutive assessments showed the highest coefficients (β = 0.29 to 0.78; all ps ≤ 0.05). Cross-loading parameters (β = 0.06 to 0.19; ps ≤ 0.05) revealed that fatigue frequently predicted subsequent depression, insomnia, and pain, whereas anxiety predicted insomnia.

CONCLUSIONS

Fatigue and anxiety appear to constitute important risk factors of other cancer-related symptoms and should be managed appropriately early during the cancer care trajectory.

Assessment of cancer pain management knowledge in southwest China: a survey of 259 physicians from small city and county hospitals

BACKGROUND

Pain management is a critical issue in the care of cancer patients in China, especially in small city and county hospitals in southwest China.

OBJECTIVE

The study intended to determine Chinese physicians' competence in cancer pain management and to assess their opinions on barriers to optimal pain management.

DESIGN

A questionnaire on pain management was given to 259 fellows after their general orientation meeting at a tertiary teaching hospital. The questionnaire was adapted from an earlier study by the Eastern Cooperative Oncology Group (ECOG).

RESULTS

The majority of the fellows believed that 70% of cancer patients suffer pain. Nearly 90% (224/259) indicated that their training in cancer pain management was poor. The fellows stated that concern about morphine addiction was the primary reason they hesitated to prescribe opioids, and they identified inadequate assessment of cancer pain as the most significant barrier to optimal management of cancer pain.

CONCLUSION

The study reflects to some extent the state of pain management in hospitals in southwest China. Medical students and physicians in China need improved pain management education.

Meta-analysis of cultural differences in Western and Asian patient-perceived barriers to managing cancer pain

PURPOSE

barriers to managing cancer pain contribute to cancer patients' reluctance to report pain and use prescribed analgesics, resulting in inadequate pain control. Patients' perceived barriers to managing cancer pain may be influenced by culture. This meta-analysis compared differences in Western and Asian patient-perceived barriers to managing cancer pain.

METHODS

the literature was systematically reviewed to compare pain barriers in Western and Asian cancer patients in 22 studies that used Ward's Barrier Questionnaire. Differences in weighted barrier scores were compared by meta-regression analysis.

RESULTS

Asian cancer patients had higher barrier scores than Western patients, except for barriers of 'good patient', 'side effects', 'distract physician', 'fear of injections', and 'addiction'. Meta-regression analysis indicated that Asian patients' perceived pain barriers differed significantly from those of Western patients for disease progression (weighted mean difference [WMD] = 1.32; 95% confidence interval [CI] 0.80, 1.84, p < 0.0001), tolerance (WMD = 1.63; 95% CI 0.91, 2.36, p < 0.0001), fatalism (WMD = 0.89; 95% CI 0.28, 1.52, p = 0.004), and total score (WMD = 0.82; 95% CI 0.36, 1.28, p < 0.0001).

CONCLUSION

Asian patients' perceived barriers to managing cancer pain were significantly higher than those for Western patients (especially for concerns about disease progression, tolerance, and fatalism). Asian cancer patients need to be assessed and carefully treated for perceived barriers to optimize cancer pain management.

Do educational interventions improve cancer patients' quality of life and reduce pain intensity? Quantitative systematic review

AIMS

This paper reports a quantitative systematic review of the effects of educational interventions on quality of life, pain intensity and pain interference in cancer patients.

BACKGROUND

Cancer pain has a marked negative impact on quality of life, and this has become an important issue in discussions of treatment options. Patient education seems to be effective in pain management, but no review has been published with quality of life as an outcome measure.

DATA SOURCES

Relevant publications from 2000 to 2010 were identified in six databases (Medline, CIHAHL, PubMed, EMBASE, PsycINFO and DARE) and by means of hand-searches. All randomized controlled trial studies of pain-education programmes for cancer patients were considered, and a quantitative review of effectiveness carried out.

REVIEW METHODS

Studies were critically appraised by three independent reviewers, and the Jadad score was used to assess the quality of those included.

RESULTS

Four studies meeting the inclusion criteria were used, after methodological quality assessment. Pain intensity and pain interference were significantly reduced after education, but statistical change in quality of life was not found in any of the studies.

CONCLUSIONS

Pain and quality of life are complex matters, and quality of life might not be a sensitive indicator of the effectiveness of pain education. To improve quality of life and reduce the severity of pain in cancer patients, individualized care, recognition of variations in patient experience, and a multi-disciplinary approach are required. Further research is recommended into patients' preferences of any educational intervention, and into the quality of existing education programmes and the expertise of the healthcare professionals concerned.

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.
