Development and Validation of an Instrument for Measuring Attitudes and Beliefs about Complementary and Alternative Medicine (CAM) Use among Cancer Patients

Feasibility of implementing acupuncture in medically underserved breast cancer survivors (FAB): A protocol

Nearly 94% of breast cancer survivors experience one or more symptoms or side effects during or after endocrine therapy. Joint pain, hot flashes, sleep disturbance, fatigue, depression, and anxiety are the most common concurrent symptoms, some of which can persist for 5 to 10 years. Acupuncture is a holistic modality that addresses multiple symptoms and side effects in a single therapy. Acupuncture has not yet been investigated for its effectiveness in treating the multiple symptoms experienced by breast cancer survivors receiving endocrine therapy. Medically underserved breast cancer survivors typically have limited access to acupuncture. The barriers limiting access to acupuncture need to be removed to enable equal access to breast cancer survivors for this evidence-based treatment. Thus, we developed a randomized controlled trial with a 5-week acupuncture intervention versus usual care for medically underserved breast cancer survivors. Mixed methods (semi-structured interviews, surveys, study notes) will be used to obtain in-depth understanding of barriers and facilitators for eventual implementation of the acupuncture intervention. This study will facilitate the widespread implementation, dissemination, and sustained utilization of acupuncture for symptom management among medically underserved breast cancer survivors receiving endocrine therapy.

Attitudes and beliefs regarding complementary and alternative medicine in a diverse gynecologic oncology patient population

Objectives

To measure prevalence of complementary and alternative medicine (CAM) use in a diverse gynecologic oncology patient population and evaluate how attitudes and beliefs regarding CAM relate to demographic factors.

Methods

A validated Attitudes and Beliefs about Complementary and Alternative Medicine (ABCAM) survey was distributed to patients with gynecologic malignancy. Results were evaluated using Pearson's Chi-squared and Fisher's exact tests for categorical variables and Wilcoxon ranks sum and Kruskal-Wallace tests for non-normally distributed variables.

Results

One-hundred thirty patients completed the ABCAM survey. Self-reported race and ethnicity included Asian or Pacific Islander (n = 54; 42%), Hispanic/Latino (n = 23; 18%), White (n = 21; 16%), Black or African American (n = 20; 15%), American Indian/Alaska Native (n = 8; 6.2%) and Other (n = 4; 3.1%). Twenty-four respondents (18%) reported use of CAM. There was a significant difference in expected benefits to CAM between respondents of different races/ethnicities (p < 0.001). Black and Asian respondents reported greater expected benefit to CAM. Hispanic/Latino, American Indian/Alaskan Native, and White respondents reported fewer expected benefits. A significant association was found between perceived barriers to CAM and race/ethnicity (p 0.043), with Asian, Hispanic/Latino and White respondents perceiving more barriers while Black and American Indian/Alaskan Natives reported perceiving fewer barriers to CAM. Respondents with incomes greater than $100,000 reported fewer barriers to CAM.

Conclusions

Use of CAM among gynecologic oncology patients is lower than previously thought. Income, race, and ethnicity inform patient engagement with CAM and can be used to better tailor the provision of evidence-based CAM interventions to benefit a greater number of gynecologic cancer patients.

Predictors of herbal medicine use among cancer patients

PURPOSE

Moroccan studies have shown a high frequency of use of traditional and complementary medicines (T&CM). No survey has investigated the predictive factors of the use of traditional herbal medicine. This study aims to assess the prevalence, the determinants, and the predictors of this use.

METHODS

At the regional oncology center of Beni Mellal, we conducted a descriptive and analytical cross-sectional study with 530 adult cancer patients chosen by quota sampling. A 54-item questionnaire was used to perform the face-to-face survey. The Complementary and Alternative Medicine (CAM) healthcare model was used to create this instrument.

RESULTS

The prevalence of traditional herbal medicine use was 36.6%. Several variables of the conceptual model were associated with the use of herbal medicine (gender, attitude, and belief towards T&CM, financial resources, and clinical characteristics of patients) (p < 0.05). Predictors of traditional herbal medicine use were female gender (OR = 4.687; p < 0.000), social impact of cancer (OR = 2.314; p < 0.05), emotional impact of cancer (OR = 2.314; p < 0. 05), expected benefits of T&CM use (OR = 3.453; p < 0.000), perceived scientific barriers (OR = 0.580; p < 0.000), perceived socioeconomic barriers (OR = 0.657; p < 0.005), and social norms of relatives (OR = 3.238; p < 0.000).

CONCLUSION

The use of herbal medicine is quite frequent. The profile of users is represented by women who experience pain and the psychosocial impact of cancer and who have positive beliefs about TCMs, are influenced by their relatives and who did not perceive the barriers of this use.

What if Acupuncture Were Covered by Insurance for Pain Management? A Cross-Sectional Study of Cancer Patients at One Academic Center and 11 Community Hospitals

OBJECTIVE

In response to the national opioid crisis, governmental and medical organizations have called for broader insurance coverage of acupuncture to improve access to nonpharmacologic pain therapies, especially in cancer populations, where undertreatment of pain is prevalent. We evaluated whether cancer patients would be willing to use insurance-covered acupuncture for pain.

DESIGN AND SETTING

We conducted a cross-sectional survey of cancer patients with pain at one academic center and 11 community hospitals.

METHODS

We used logistic regression models to examine factors associated with willingness to use insurance-covered acupuncture for pain.

RESULTS

Among 634 cancer patients, 304 (47.9%) reported willingness to use insurance-covered acupuncture for pain. In univariate analyses, patients were more likely to report willingness if they had severe pain (odds ratio [OR] = 1.59, 95% confidence interval [CI] = 1.03-2.45) but were less likely if they were nonwhite (OR = 0.59, 95% CI = 0.39-0.90) or had only received high school education or less (OR = 0.46, 95% CI = 0.32-0.65). After adjusting for attitudes and beliefs in multivariable analyses, willingness was no longer significantly associated with education (adjusted OR [aOR] = 0.78, 95% CI = 0.50-1.21) and was more negatively associated with nonwhite race (aOR = 0.49, 95% CI = 0.29-0.84).

CONCLUSIONS

Approximately one in two cancer patients was willing to use insurance-covered acupuncture for pain. Willingness was influenced by patients' attitudes and beliefs, which are potentially modifiable through counseling and education. Further research on racial disparities is needed to close the gap in utilization as acupuncture is integrated into insurance plans in response to the opioid crisis.

Fear of analgesic side effects predicts preference for acupuncture: a cross-sectional study of cancer patients with pain in the USA

PURPOSE

Approximately one in two cancer patients globally are under-treated for pain. Opioids and other analgesics represent the mainstay of cancer pain management; however, barriers to their use are well-documented. We evaluated whether acupuncture would be a preferable treatment option among cancer patients with attitudinal barriers to pharmacological pain management.

METHODS

We conducted a cross-sectional survey of cancer patients at a tertiary urban cancer center and eleven suburban/rural hospitals in the Northeastern United States. We assessed attitudinal barriers to pharmacological pain management with the Barriers Questionnaire (BQ-13). The BQ-13 consists of two subscales: pain management beliefs and analgesic side effects. We also asked patients whether they prefer acupuncture, analgesics, or have no preference between these two modalities for pain management. Covariates included sociodemographics, clinical characteristics, and attitudes/beliefs about acupuncture. We used logistic regression to examine the association between attitudinal barriers and acupuncture preference.

RESULTS

Among 628 patients, 197 (31.4%) preferred acupuncture for pain management, 146 (23.3%) preferred analgesics, and 285 (45.4%) had no preference. The highest reported attitudinal barriers were fear of addiction and fear of analgesic-associated constipation and nausea. Adjusting for covariates, we found that attitudinal barriers related to fear of analgesic side effects were significantly associated with acupuncture preference (adjusted odds ratio [AOR] 1.45, 95% confidence interval [CI] 1.17-1.81), but barriers related to pain management beliefs were not (AOR 1.17, 95% CI 0.91-1.51). Attitudes/beliefs about acupuncture (i.e., greater expected benefits, fewer perceived barriers, and more positive social norms) and female gender also predicted acupuncture preference, whereas race and educational status did not.

CONCLUSION

Acupuncture may be a preferable treatment option among cancer patients at risk of inadequately controlled pain due to fear of analgesic side effects. Evidence-based integration of acupuncture and analgesics, guided by patient treatment preferences, represents an essential aspect of patient-centered care and has potential to address unmet cancer pain management needs.

Evaluating Cancer Patients' Expectations and Barriers Toward Traditional Chinese Medicine Utilization in China: A Patient-Support Group-Based Cross-Sectional Survey

Background: Traditional Chinese medicine (TCM) is widely used among Chinese cancer patients. However, little is known about Chinese patients’ expectations and barriers toward using TCM for cancer. Methods: We conducted a cross-sectional survey within a patient-support group, the Beijing Anti-Cancer Association. We measured the outcome, Chinese cancer survivors’ expectations and barriers toward TCM utilization, using a modified version of ABCAM (Attitudes and Beliefs towards Complementary and Alternative Medicine), the ABTCM (Attitudes and Beliefs towards Traditional Chinese Medicine). We used multivariate models to evaluate the impact of socioeconomic status and clinical factors on their expectations and barriers (including treatment concerns and logistical challenges domain) toward TCM. Results: Among 590 participants, most patients expected TCM to boost their immune system (96%), improve their physical health (96%), and reduce symptoms (94%). Many had logistical challenges (difficulty decocting herbs (58%) and finding a good TCM physician (55%)). A few were concerned that TCM might interfere with conventional treatments (7.6%), and that many TCM treatments are not based on scientific research (9.1%). In the multivariable regression model, age ≤60 years was independently associated with higher expectation score (P = .031). Age ≤60 years (coefficient 5.0, P = .003) and localized disease (coefficient 9.5, P = .001) were both associated with higher treatment concerns. Active employment status (coefficient 9.0, P = .008) and localized disease (coefficient 7.5, P = .030) were related to more logistical challenges. Conclusion: Age and cancer stage were related to Chinese cancer patients’ perceived expectations and barriers toward TCM use. Understanding these attitudes is important for reshaping the role that TCM plays in China’s patient-centered comprehensive cancer care model.

Development and validation of a tool to evaluate Inpatient Beliefs, Expectations and Attitudes toward Reflexology (IBEAR-16)

BACKGROUND

The integration of manual therapies, including reflexology, into conventional care settings is growing extensively. Patients' beliefs, attitudes and expectations toward these therapies interact with their outcomes, but currently there are no validated tools to evaluate these factors. We aimed to design and to validate such a tool specifically targeted into reflexology.

METHODS

Following input of a multidisciplinary team of experts, the self-administered Inpatient Beliefs, Expectations and Attitudes toward Reflexology (IBEAR) questionnaire was constructed, containing 25 items, 8 referring to demographics and 17 specifically addressing reflexology. Cronbach's alpha was computed to evaluate the questionnaire's internal reliability, and factor analysis was used for further validation (232 patients). Pearson coefficient and Kappa tests were used to test and retest (within 48 hours) the questionnaire on a group of 199 patients, to assure clarity and reliability.

RESULTS

For the 232 questionnaires collected, the computed Cronbach's alpha coefficient was 0.716 (acceptable reliability). Factor analysis pointed to two content areas separated into four items addressing attitudes and expectations and five items focusing on beliefs and attitudes. In the test-retest stage, 199 participants filled in the questionnaire for a second time. The Pearson coefficient for all questions ranged between 0.73 and 0.94 (good to excellent correlation) and Kappa scores ranged between 0.66 and 1.0 (moderate to high reliability). Consequently, one of the questions was removed from the IBEAR.

CONCLUSIONS

The present study provides evidence that the proposed IBEAR questionnaire with 16 items is a valid and reliable tool for evaluation of inpatients' beliefs, expectations and attitudes toward reflexology.

Acupuncture versus medication for pain management: a cross-sectional study of breast cancer survivors

AIM OF THE STUDY

Breast cancer survivors who take aromatase inhibitors (AI) often suffer from chronic pain. Emerging evidence supports the use of acupuncture as an effective pain management strategy for this condition, but its acceptability among cancer survivors is unknown. We evaluated breast cancer survivors' preferences for acupuncture as compared with medication use and identified factors predictive of this preference.

METHODS

We conducted a cross-sectional study among breast cancer survivors who were currently, or had been, taking an AI. The primary outcome was degree of preference for acupuncture as compared with medication for pain management. We conducted multivariate logistic regression analyses to evaluate the effects of socioeconomic status (SES) factors and health beliefs on treatment preference.

RESULTS

Among 592 participants, 160 (27.0%) preferred acupuncture, 153 (25.8%) preferred medication and 279 (47.1%) had no clear preference. In a multivariate analysis that only included SES, higher education and white race were significantly associated with greater preference for acupuncture. When health beliefs were added, SES effects were attenuated, while greater expectation of acupuncture's effect, lower perceived barriers to its use, higher social norm (endorsement from family members and healthcare professionals) related to acupuncture and higher holistic health beliefs were associated with greater preference for acupuncture.

CONCLUSION

We found similar rates of preference for acupuncture versus medication among breast cancer survivors for pain management. Specific attitudes and beliefs predicted such preferences, highlighting the importance of a patient-centred approach to align patient beliefs and preferences with therapeutic options for more effective pain management.

Barriers to Acupuncture Use Among Breast Cancer Survivors: A Cross-Sectional Analysis

Introduction: Increasing evidence suggests that acupuncture may be helpful to manage common symptoms and treatment side effects among breast cancer (BC) survivors. Acupuncture usage among BC survivors remains low with little known about the barriers to its utilization. We evaluated perceived barriers to acupuncture use among BC survivors and explored the sociodemographic variations of such barriers. Methods: We conducted a cross-sectional analysis at an urban academic cancer center on 593 postmenopausal women with a history of stage I-III hormone receptor-positive BC who were taking or had taken an aromatase inhibitor. We used the modified Attitudes and Beliefs about Complementary and Alternative Medicine instrument to evaluate patients’ perceived barriers to acupuncture. Multiple linear regression analysis was performed to determine sociodemographic factors associated with perceived barrier scores. Results: The most common barriers were lack of knowledge about acupuncture (41.6%), concern for lack of insurance coverage (25.0%), cost (22.3%), and difficulty finding qualified acupuncturists (18.6%). Compared with whites, minority patients had higher perceived barriers to use acupuncture (β coefficient = 1.63, 95% confidence interval = 0.3-2.9, P = .013). Patients with lower education had higher barriers to use acupuncture (β coefficient = 4.23, 95% confidence interval = 3.0-5.4, P < .001) compared with patients with college education or above. Conclusion: Lack of knowledge and concerns for insurance coverage and cost are the common barriers to acupuncture use among BC survivors, especially among minority patients with lower education. Addressing these barriers may lead to more equitable access to acupuncture treatment for BC survivors from diverse backgrounds.

Race, Pain, and Beliefs Associated with Interest in Complementary and Alternative Medicine among Inner City Veterans

OBJECTIVE

To investigate the prevalence and determinants of complementary and alternative medicine (CAM) interest level among a racially diverse cohort of inner city veterans who receive primary care at the VA Medical Center.

DESIGN

Cross-sectional survey study

SETTING

Philadelphia VA Medical Center

SUBJECTS

Primary care patients (n = 258) METHODS: Interest in CAM was measured using a single item question. Patient treatment beliefs were assessed using validated instruments. We evaluated factors associated with patient interest in CAM using a multivariate logistic regression model.

RESULTS

In this sample of 258 inner city primary care VA patients, interest in CAM was high 80% (n = 206). Interest in CAM was strongly associated with African American race [adjusted odds ratio (AOR) 2.19, 95% Confidence Interval (CI) 1.05-4.60, P = 0.037], higher levels of education (AOR 4.33, 95% CI 1.80-10.40, P = 0.001), presence of moderate to severe pain (AOR 2.02, 95% CI 1.02-4.78, P = 0.043), and expectations of benefit from CAM use (AOR 1.21, 95% CI 1.06-1.36, P = 0.004).

CONCLUSIONS

CAM approaches have broad appeal within this inner city cohort of veterans, particularly among African Americans, those that experience pain and those that expect greater benefit from CAM. These findings may inform the development of patient-centered integrative pain management for veterans.

Do attitudes and beliefs regarding complementary and alternative medicine impact its use among patients with cancer? A cross-sectional survey

BACKGROUND

Complementary and alternative medicine (CAM) incorporates treatments used by cancer survivors in an attempt to improve their quality of life. Although population studies have identified factors associated with its use, to the best of the authors knowledge, assessment of why patients use CAM or the barriers against its use have not been examined to date.

METHODS

The authors conducted a cross-sectional survey study in the thoracic, breast, and gastrointestinal medical oncology clinics at an academic cancer center. Clinical and demographic variables were collected by self-report and chart abstraction. Attitudes and beliefs were measured using the validated Attitudes and Beliefs about CAM (ABCAM) instrument. This instrument divides attitudes and beliefs into 3 domains: expected benefits, perceived barriers, and subjective norms.

RESULTS

Among 969 participants (response rate, 82.7%) surveyed between June 2010 and September 2011, patient age ≤65 years, female sex, and college education were associated with a significantly greater expected benefit from CAM (P<.0001 for all). Nonwhite patients reported more perceived barriers to CAM use compared with white patients (P<.0001), but had a similar degree of expected benefit (P = .76). In a multivariate logistic regression analysis, all domains of the ABCAM instrument were found to be significantly associated with CAM use (P<.01 for all) among patients with cancer. Attitudes and beliefs regarding CAM explained much more variance in CAM use than clinical and demographic variables alone.

CONCLUSIONS

Attitudes and beliefs varied by key clinical and demographic characteristics, and predicted CAM use. By developing CAM programs based upon attitudes and beliefs, barriers among underserved patient populations may be removed and more patient centered care may be provided.

Mixed Methods in CAM Research: A Systematic Review of Studies Published in 2012

Background. Mixed methods research uses qualitative and quantitative methods together in a single study or a series of related studies. Objectives. To review the prevalence and quality of mixed methods studies in complementary medicine. Methods. All studies published in the top 10 integrative and complementary medicine journals in 2012 were screened. The quality of mixed methods studies was appraised using a published tool designed for mixed methods studies. Results. 4% of papers (95 out of 2349) reported mixed methods studies, 80 of which met criteria for applying the quality appraisal tool. The most popular formal mixed methods design was triangulation (used by 74% of studies), followed by embedded (14%), sequential explanatory (8%), and finally sequential exploratory (5%). Quantitative components were generally of higher quality than qualitative components; when quantitative components involved RCTs they were of particularly high quality. Common methodological limitations were identified. Most strikingly, none of the 80 mixed methods studies addressed the philosophical tensions inherent in mixing qualitative and quantitative methods. Conclusions and Implications. The quality of mixed methods research in CAM can be enhanced by addressing philosophical tensions and improving reporting of (a) analytic methods and reflexivity (in qualitative components) and (b) sampling and recruitment-related procedures (in all components).
