Perceptions about complementary and alternative medicine use among Chinese immigrant parents of children with cancer

Integrative Medicine Across the Pediatric Cancer Care Trajectory: A Narrative Review

PURPOSE OF THE REVIEW

Children and adolescents with cancer, along with their parents and other informal caregivers, often report using complementary and alternative medicine (CAM) during active oncology and hemato-oncology treatment. Some adopt an "alternative" approach to conventional medical care, which often entails the use of these practices without the knowledge of the treating pediatrician. In contrast, many others search for consultation provided by a pediatric integrative oncology (IO) practitioner working with the conventional medical team. IO seeks to provide evidence-based complementary medicine therapies, many of which have been shown to augment conventional supportive and palliative care, while ensuring the patient's safety. The present narrative review examines the current state of and future direction for the IO setting of care.

RECENT FINDINGS

A large body of published clinical research supports the effectiveness of leading Pediatric IO modalities, while addressing potential safety-related concerns. Despite the growing amount of clinical research supporting the beneficial effects and implementation of Pediatric IO models of care, there is still a need for further studies in order to establish clinical guidelines in the treatment of children and adolescents with cancer. Such IO-directed guidelines will need to address both the effectiveness and the safety of the CAM modalities being used in pediatric oncology and hemato-oncology settings, promoting a better understanding among pediatric healthcare professionals and helping them understand the indications for referral to the IO treatment service.

Factors Associated with Insured Children's Use of Physician Visits, Dentist Visits, Hospital Care, and Prescribed Medications in the United States: An Application of Behavioral Model of Health-Services Use

This study is the first to examine factors in the utilization of physician services, dentist services, hospital care, and prescribed medications focusing exclusively on insured children in the United States. Data describing 48,660 insured children were extracted from the 2021 National Survey of Children's Health. Children in the present sample were covered by private health insurance, public health insurance, or other health insurance. Logistic regression results showed self-reported health to be negatively associated with physician visits, hospital-care use, and prescription use, but teeth condition to be positively associated with dentist visits. Physician visits were associated negatively with age, Hispanic ethnicity, Asian ethnicity, family income at or below 200% of the federal poverty level, and other health insurance, but positively with parental education and metropolitan residency. Dentist visits were associated positively with girls, age, and parental education, but negatively with Asian ethnicity and public health insurance. Use of hospital care was associated negatively with age and Asian ethnicity, but positively with parental education and public health insurance. Use of prescriptions was associated positively with age, Black ethnicity, parental education, and public health insurance, but negatively with Hispanic ethnicity, Asian ethnicity, and family income at or below 200% of the federal poverty level. Implications included the expansion of public health insurance, promotion of awareness of medicine discount programs, and understanding of racial/ethnic minorities' cultural beliefs in health and treatment.

Use of Chronic Prescription Medications and Prevalence of Polypharmacy in Survivors of Childhood Cancer

BACKGROUND

As survivors of childhood cancer age, development of cancer treatment-related chronic health conditions often occur. This study aimed to describe the pattern of chronic prescription medication use and identify factors associated with polypharmacy among survivors of childhood cancer.

METHODS

This was a retrospective study conducted at the pediatric oncology long-term follow-up clinic in Hong Kong. Eligible subjects included survivors who were (1) diagnosed with cancer before 18 years old, (2) were at least 3 years post-cancer diagnosis and had completed treatment for at least 30 days, and (3) receiving long-term follow-up care at the study site between 2015 and 2018. Dispensing records of eligible survivors were reviewed to identify medications taken daily for ≥30 days or used on an "as needed" basis for ≥6 months cumulatively within the past 12-month period. Polypharmacy was defined as the concurrent use of ≥5 chronic medications. Multivariable log-binomial modeling was conducted to identify treatment and clinical factors associated with medication use pattern and polypharmacy.

RESULTS

This study included 625 survivors (mean current age = 17.9 years, standard deviation [SD] = 7.2 years) who were 9.2 [5.2] years post-treatment. Approximately one-third (n = 219, 35.0%) of survivors were prescribed at least one chronic medication. Frequently prescribed medication classes include systemic antihistamines (26.5%), sex hormones (19.2%), and thyroid replacement therapy (16.0%). Overall prevalence of polypharmacy was 5.3% (n = 33). A higher rate of polypharmacy was found in survivors of CNS tumors (13.6%) than in survivors of hematological malignancies (4.3%) and other solid tumors (5.3%) (P = .0051). Higher medication burden was also observed in survivors who had undergone cranial radiation (RR = 6.31; 95% CI = 2.75-14.49) or hematopoietic stem-cell transplantation (HSCT) (RR = 3.53; 95% CI = 1.59-7.83).

CONCLUSION

Although polypharmacy was observed in a minority of included survivors of childhood cancer, chronic medication use was common. Special attention should be paid to survivors of CNS tumors and survivors who have undergone HSCT or cranial radiation. These individuals should be monitored closely for drug-drug interactions and adverse health outcomes that may result from multiple chronic medications, particularly during hospitalization in an acute care setting.

Clinical ascertainment of health outcomes in Asian survivors of childhood cancer: a systematic review

PURPOSE

Survivorship in children with cancer comes at a cost of developing chronic treatment-related complications. Yet, it is still an under-researched area in Asia, which shares the largest proportion of the global childhood cancer burden given its vast population. This systematic review summarizes existing literature on clinically ascertained health outcomes in Asian survivors of childhood cancer.

METHODS

A search was conducted on Ovid Medline and EMBASE for studies that focused on survivors of childhood cancer from countries in East and Southeast Asia; adopted post-treatment clinical ascertainment of organ-specific toxicities or/and secondary malignancy. Studies were excluded if health outcomes were assessed during the acute treatment.

RESULTS

Fifty-nine studies, enrolling a total of 13,442 subjects, were conducted on survivors of leukemia (34%), CNS tumor (14%), and cohorts of survivors with heterogeneous cancer diagnoses (52%). The studies used different medical evaluation methods to assess cardiovascular (15%), metabolic and infertility (32%), and neurological/neurocognitive (20%) outcomes in survivors. The collective findings suggest potential differences in the prevalence of certain late effects (e.g., secondary malignancy and obesity) among Asian and non-Asian populations, which may reflect differences in treatment regimens, practice, genetic variations, or/and socioeconomic disparity.

CONCLUSIONS

We recommend developing collaborative initiatives to build a regional repository of systematically assessed health outcomes and biospecimens to investigate treatment, social-environmental and genetic predictors, and interventions for late effects in this population.

IMPLICATIONS FOR CANCER SURVIVORS

The existing types of chronic health problems identified in this review suggest the need for active screening, better access to survivorship care, and promotion of protective health behavior in Asia.

Global Use of Traditional and Complementary Medicine in Childhood Cancer: A Systematic Review

Purpose

Traditional and complementary medicine (T&CM) strategies are commonly used in pediatric oncology. Patterns may vary based on country income. We systematically reviewed published studies describing T&CM use among pediatric oncology patients in low-income countries (LIC/LMIC), middle-income countries (UMIC), and high-income countries (HIC). Objectives included describing estimated prevalence of use, reasons for use, perceived effectiveness, modalities used, rates of disclosure, and reporting of delayed or abandoned treatment.

Methods

MEDLINE, EMBASE, Global Health, CINAHL, PsycINFO, Allied and Complementary Medicine Database, Cochrane Database of Systematic Reviews, and ProceedingsFirst were searched. Inclusion criteria were primary studies involving children younger than the age of 18 years, undergoing active treatment of cancer, and any T&CM use. Exclusion criteria included no pediatric oncology–specific outcomes and studies involving only children off active treatment. Data were extracted by two reviewers using a systematic data extraction form determined a priori.

Results

Sixty-five studies published between 1977 and 2015 were included, representing 61 unique data sets and 7,219 children from 34 countries. The prevalence of T&CM use ranged from 6% to 100%. Median rates of use were significantly different in LIC/LMIC (66.7% ± 19%), UMIC (60% ± 26%), and HIC (47.2% ± 20%; P = .02). Rates of disclosure differed significantly by country income, with higher median rates in HIC. Seven studies reported on treatment abandonment or delays.

Conclusion

The use of T&CM in pediatric oncology is common worldwide, with higher median prevalence of use reported in LIC/LMIC. Further research is warranted to examine the impact on treatment abandonment and delay.

Cancer patients taking herbal medicines: A review of clinical purposes, associated factors, and perceptions of benefit or harm

ETHNOPHARMACOLOGICAL RELEVANCE

Cancer patients in all cultures are high consumers of herbal medicines (HMs) usually as part of a regime consisting of several complementary and alternative medicine (CAM) modalities, but the type of patient, the reasons for choosing such HM-CAM regimes, and the benefits they perceive from taking them are poorly understood. There are also concerns that local information may be ignored due to language issues. This study investigates aspects of HM-CAM use in cancer patients using two different abstracting sources: Medline, which contains only peer-reviewed studies from SCI journals, and in order to explore whether further data may be available regionally, the Thai national databases of HM and CAM were searched as an example.

MATERIALS AND METHODS

The international and Thai language databases were searched separately to identify relevant studies, using key words chosen to include HM use in all traditions. Analysis of these was undertaken to identify socio-demographic and clinical factors, as well as sources of information, which may inform the decision to use HMs.

RESULTS

Medline yielded 5638 records, with 49 papers fitting the criteria for review. The Thai databases yielded 155, with none relevant for review. Factors associated with HM-CAM usage were: a younger age, higher education or economic status, multiple chemotherapy treatment, late stage of disease. The most common purposes for using HM-CAM cited by patients were to improve physical symptoms, support emotional health, stimulate the immune system, improve quality of life, and relieve side-effects of conventional treatment.

CONCLUSIONS

Several indicators were identified for cancer patients who are most likely to take HM-CAM. However, interpreting the clinical reasons why patients decide to use HM-CAM is hampered by a lack of standard terminology and thematic coding, because patients' own descriptions are too variable and overlapping for meaningful comparison. Nevertheless, fears that the results of local studies published regionally are being missed, at least in the case of Thailand, appeared to be unfounded.

Characteristics associated with the use of complementary health approaches among long-term cancer survivors

PURPOSE

This study aims to identify the prevalence and characteristics of long-term adult cancer survivors who use complementary health approaches (CHA).

METHODS

Participants completed the Follow-up Care Use Among Survivors (FOCUS) Survey, a cross-sectional investigation of long-term cancer survivors. The use of CHA and reasons for use were assessed. A multivariable logistic regression model was applied to identify if predisposing, enabling, and need characteristics described in the Complementary and Alternative Medicine Healthcare Model were associated with CHA use in the past year.

RESULTS

Long-term cancer survivors in the study (N = 1,666) were predominately female (62%) and older (mean age = 69.5), with breast, prostate, colorectal, ovarian, and endometrial cancers. Thirty-three percent of survivors used CHA in the past year. Common reasons for CHA use were to relieve stress (28%), treat or prevent cancer (21%), relieve cancer-related symptoms (18%), and deal with another condition (18%). Predisposing (i.e., higher optimism) and need factors (i.e., experienced cancer-related symptoms, ever had depression/anxiety) were significantly associated with CHA (p-values < .05). Enabling factors (i.e., insurance coverage, financial resources) were not.

CONCLUSIONS

Cancer survivors continue to report a high prevalence of recent CHA use more than 5 years after initial diagnosis. Healthcare providers should be aware of increased use of CHA among subgroups of long-term cancer survivors in order to guide safe and optimal use.

Decision-making related to complementary and alternative medicine use by people with Type 2 diabetes: a qualitative study

AIMS AND OBJECTIVES

To explore how complementary and alternative medicine (CAM) users make decisions about CAM use. Specifically, an exploration of the processes used by people with Type 2 diabetes, related to the assessment of information sources, factors influencing decision-making and the role of other key individuals, was undertaken.

BACKGROUND

Patients with chronic illnesses increasingly seek to use CAM to improve their well-being. Currently, however, the decision-making processes related to CAM use among people with Type 2 diabetes are poorly understood.

METHODS

An exploratory study using a naturalistic design, with in-depth semi-structured interviews, was undertaken. Purposive sampling was used to recruit participants with Type 2 diabetes who used CAM alongside conventional medicine. The data were analysed in a three-step coding process. Ethical approval was gained from a human research ethics committee.

RESULTS

Evidence about CAM use from interview data was consistent with a multi-dimensional decision-making processes used by participants. Four major categories emerged: recognising the need for using CAM; assessing the potential CAM before use; matching CAM use to personal philosophy; and ongoing evaluation of CAM.

CONCLUSION

As diabetes affects the entirety of a person's being self-management, incorporating CAMs has become a way of controlling the condition and improving well-being. It is important for health professionals to consider clients' CAM use and to incorporate this information, where appropriate, into management plans.

RELEVANCE TO CLINICAL PRACTICE

Health care professionals should be aware of patients who use CAM while under conventional medical care and should discuss CAM use at various points in the client journey to facilitate better communication.
