Prevalence and determinants of using complementary and alternative medicine for the treatment of chronic illnesses: A multicenter study in Bangladesh

BACKGROUND

While conventional medicine (CM) is commonly used to treat non-communicable diseases (NCDs), complementary and alternative medicine (CAM) is gaining popularity as a healthcare option in Bangladesh. We aimed to investigate the prevalence and factors associated with using CAM solely and using CAM in conjunction with CM for chronic illness treatment among NCD patients in Bangladesh.

METHODS

A multicenter cross-sectional study was conducted, including 549 adults with a confirmed chronic illness diagnosis from three tertiary care hospitals in Dhaka city. Interviews were used to gather socio-demographic data, while medical records were used to get information on chronic illnesses. A multinomial logistic regression model was used to determine the associated factors of utilizing CAM primarily and CAM use in conjunction with CM to manage the chronic disease.

RESULTS

Out of 549 NCD patients (282 women [51.4%], mean [standard deviation] age 45.4 [12.8] years), 180 (32.8%) ever used CAM for the treatment of chronic illness. Also, 15.3% of patients exclusively used CAM among the NCD patients, while 17.5% used CAM in conjunction with CM. Homeopathy medicine was the most prevalent type of treatment among CAM users (52.2%). Furthermore, 55.5% of CAM users said they used it due to its less adverse effects, and 41.6% trusted its effectiveness for chronic illness. Elderly patients (≥60 years) preferred CAM in complementary with CM, but they did not rely only on CAM. According to the multinomial regression analysis, unmarried patients, predominantly in the younger age group, adopted CAM significantly for chronic illness treatment (Relative risk ratio, RRR = 0.29, 95% CI = 0.12-0.71, reference = Unmarried). Patients in the high-income group used CAM in conjunction with CM (RRR = 6.26, 95% CI = 1.35-18.90, reference: low-income), whereas patients in the high-income group did not rely on CAM alone (RRR = 0.99, 95% CI = 0.34-2.85).

CONCLUSION

Although CM remains the mainstream of health care in Bangladesh, CAM services play an essential role in people's health care, particularly in treating chronic illnesses. Physicians of Bangladesh should be aware that their patients may be using other services and be prepared to ask and answer questions regarding the risks and benefits of using CAM in addition to regular medical care. Thus, clinicians required to follow best-practice guidelines, which are currently not practiced in Bangladesh, when disseminating information regarding integrative techniques that combine CM and CAM approaches.

Complementary Therapies Used by Indonesians With Myocardial Infarction

This descriptive, cross-sectional study was conducted to identify types, frequency, methods, duration, and purpose of complementary therapies used by Indonesians with myocardial infarction. The majority of the respondents used biologically based therapies, with the most common subtype being herbs. The purpose of using biologically based therapies was for health promotion.

The schism in chiropractic through the eyes of a 1st year chiropractic student

Since its inception, the chiropractic profession has been divided along ideological fault lines. These divisions have led to a profession wide schism, which has limited mainstream acceptance, utilisation, social authority and integration. The authors explore the historical origins of this schism, taking time to consider historical context, religiosity, perpetuating factors, logical fallacies and siege mentality. Evidence is then provided for a way forward, based on the positioning of chiropractors as mainstream partners in health care.

Alternative Therapy Use in Liver Transplant Recipients

Background

The extent of use of alternative therapies and the psychosocial variables predictive of their use have not been well defined in liver transplant recipients.

Objective

To determine types of alternative therapies used by liver transplant recipients and to assess psychosocial, behavioral, and quality of life variables associated with the use of alternative therapies in these patients.

Methods

Assessment of types of alternative therapies used, demographic characteristics, satisfaction with social support, coping styles, sense of personal control (mastery), quality of life, and health beliefs in 32 liver transplant recipients.

Results

Overall, 34.4% of the liver transplant recipients used a form of alternative therapy. Herbal products were used by 45% of the alternative therapy users and included milk thistle (silymarin), eclipta, and green beet leaf—all considered “hepatic tonics.” Alternative therapy users tended to have greater problem-focused coping skills than nonusers ( P = .08). Nineteen percent of the patients incurred annual out-of-pocket expense of at least $100 for alternative therapies. Patients incurring out-of-pocket expenses reported better overall health ( P = .02), were more likely to be employed ( P = .025), and had higher mastery scores ( P = .01).

Conclusions

Use of alternative therapies is common after liver transplantation. Herbal products used by liver transplant recipients are disease specific; that is, they claim to promote liver health.

Use and users of complementary and alternative medicine among people with multiple sclerosis in Denmark

BACKGROUND

It is known that complementary and alternative medicine (CAM) is popular among people with multiple Sclerosis (MS) and that use is widespread. However, very limited knowledge exists about use and users of CAM among people with MS in a Danish context.

AIMS

The overall aim of the thesis is to investigate how and why people with MS in Denmark include CAM in managing their life with a chronic disease and to discuss their experiences and beliefs linked to CAM use.  

METHODS

A mixed methods research design was applied, combining an Internet-based survey with two qualitative in-depth interview studies. A total of 6,850 people with MS from the five Nordic countries, of these 3,500 from Denmark, were invited to participate in the survey. The average response rate was 56.1%. Based on analyses of the Danish survey data, two specific issues regarding the use of CAM were selected for further investigation and two qualitative interview studies were performed (n = 17, n = 11), using program theory and meaning categorization as analytical tools.

RESULTS

The results of the study indicate that the use of CAM among people with MS is widespread in Denmark as well as in the other Nordic countries. The results furthermore suggest that this use is generally embedded in a preventative, autonomous approach to treatment and that the users' choices regarding CAM may be related to many personal factors and do not necessarily represent a distrust of the medical system.

PERSPECTIVES

The results of the study point to the relevance of healthcare professionals engaging in understanding patients' different motives for - and experiences with - using different types of treatments. Thereby, the results of the study also point to the importance of enhancing and qualifying communication between patients and representatives of conventional healthcare systems regarding the patients' use of CAM, both with the aim of mutual learning and for reasons of safety.

Regional variation in use of complementary health approaches by U.S. adults

Data from the National Health Interview Survey, 2012 Use of nonvitamin, nonmineral dietary supplements (17.9%) was greater than any other complementary health approach used by U.S. adults in 2012. The use of practitioner-based chiropractic or osteopathic manipulation was nearly twice as high in the West North Central region as in the United States overall. Use of nonvitamin, nonmineral dietary supplements was highest in the Mountain, Pacific, and West North Central regions. Use of yoga with deep breathing or meditation was approximately 40% higher in the Pacific and Mountain regions than in the United States overall. Complementary health approaches are defined as "a group of diverse medical and health care interventions, practices, products, or disciplines that are not generally considered part of conventional medicine". They range from practitioner-based approaches, such as chiropractic manipulation and massage therapy, to predominantly self-care approaches, such as nonvitamin, nonmineral dietary supplements, meditation, and yoga. This report presents estimates of the four most commonly used complementary health approaches among adults aged 18 and over in nine geographic regions, using data from the 2012 National Health Interview Survey adult alternative medicine supplement.

Usage of Complementary and Alternative Medicine (CAM) among osteoarthritis patients attending an urban multi-specialist hospital in Lagos, Nigeria

BACKGROUND

Osteoarthritis (OA), a chronic degenerative disease of synovial joints is characterised by pain and stiffness. Aim of treatment is pain relief. Complementary and alternative medicine (CAM) refers to practices which are not an integral part of orthodox medicine.

AIMS AND OBJECTIVES

To determine the pattern of usage of CAM among OA patients in Nigeria.

PATIENTS AND METHODS

Consecutive patients with OA attending orthopaedic clinic of Havana Specialist Hospital, Lagos, Nigeria were interviewed over a 6- month period st st of 1 May to 31 October 2007 on usage of CAM. Structured and open-ended questions were used. Demographic data, duration of OA and treatment as well as compliance to orthodox medications were documented.

RESULTS

One hundred and sixty four patients were studied.120 (73.25%) were females and 44(26.89%) were males. Respondents age range between 35-74 years. 66(40.2%) patients used CAM. 35(53.0%) had done so before presenting to the hospital. The most commonly used CAM were herbal products used by 50(75.8%) of CAM users. Among herbal product users, 74.0% used non- specific local products, 30.0% used ginger, 36.0% used garlic and 28.0% used Aloe Vera. Among CAM users, 35(53.0%) used local embrocation and massage, 10(15.2%) used spiritual methods. There was no significant difference in demographics, clinical characteristics and pain control among CAM users and non-users.

CONCLUSION

Many OA patients receiving orthodox therapy also use CAM. Medical doctors need to keep a wary eye on CAM usage among patients and enquire about this health-seeking behaviour in order to educate them on possible drug interactions, adverse effects and long term complications.

Development and classification of an operational definition of complementary and alternative medicine for the Cochrane collaboration

During the past decade, the Cochrane Collaboration has been an increasingly important source of information on complementary and alternative medicine (CAM) therapies. From 2007 to 2008, the Cochrane CAM Field developed a topics list that allowed us to categorize all 396 Cochrane reviews related to CAM (as of The Cochrane Library, Issue 4, 2009). This topics list is an advance in making Cochrane reviews on CAM topics accessible to the public. In this article, we discuss challenges in developing the topics list, including developing an operational efinition of CAM, deciding which reviews should be included within the CAM Field's scope, developing the structured list of CAM Field-specific topics, and determining where in the topics list the reviews should be placed. Although aspects of our operational definition of CAM are open to revision, a standardized definition provides us with an objective, reproducible, and systematic method for defining and classifying CAM therapies.

[Place of reflexotherapy and some other methods of alternative medicine in modern medical practice]

Assessment of the role and place of nontraditional methods of treatment and reflexotherapy, widely applied in hospitals is presented in the article. Besides, we become alerted regarding not serious approach of some scientists and health service managers to reflexotherapy as a whole and to one of its methods--acupuncture. An analysis of the situation developed in the legislation concerning training of reflexotherapy specialists for last 15-20 years not only in Ukraine, but also abroad was done. The article presents a historical parallel between the use of medicamentous and nonmedicamentous methods of treatment.

'Healthy Ageing' policies and anti-ageing ideologies and practices: on the exercise of responsibility

This paper explores how the exercise of the ethics of 'responsibility' for health care advanced through 'healthy ageing' and 'successful ageing' narratives in Western countries animates an array of 'authorities', including the 'anti-ageing medicine' movement as a strategy to address the anxieties of growing old in Western societies and as a tool to exercise the ethos of 'responsibility'. The choice of this type of authority as a source of guidance for self-constitution and the exercise of the 'responsible self', this paper will argue, enables the enactment of a type of late modernity notion of citizenship for ageing individuals based on principles of agelessness, health, independence and consumption power. Through interviews with anti-ageing consumers, however, it is also possible to argue the existence of tensions and contradictions that such a rigid model of self-constitution in later life produces, and the potential forms of resistance and contestations that may emerge as a result. In this way the current 'war on anti-ageing medicine' (Vincent 2003) becomes also symptomatic of bigger 'wars' taking place not only between institutions competing for control over knowledge and management of ageing, but between those in favour and against the homogenisation of life under the language of universal science, reason and market rationality.

Classification of complementary and alternative medical practices: Family physicians' ratings of effectiveness

ABSTRACTOBJECTIVETo develop a classification of complementary and alternative medicine (CAM) practices widely available in Canada based on physicians' effectiveness ratings of the therapies.DESIGNA self-administered postal questionnaire asking family physicians to rate their "belief in the degree of therapeutic effectiveness" of 15 CAM therapies.SETTINGProvince of Alberta.PARTICIPANTSA total of 875 family physicians.MAIN OUTCOME MEASURESDescriptive statistics of physicians' awareness of and effectiveness ratings for each of the therapies; factor analysis was applied to the ratings of the 15 therapies in order to explore whether or not the data support the proposed classification of CAM practices into categories of accepted and rejected.RESULTSPhysicians believed that acupuncture, massage therapy, chiropractic care, relaxation therapy, biofeedback, and spiritual or religious healing were effective when used in conjunction with biomedicine to treat chronic or psychosomatic indications. Physicians attributed little effectiveness to homeopathy or naturopathy, Feldenkrais or Alexander technique, Rolfing, herbal medicine, traditional Chinese medicine, and reflexology. The factor analysis revealed an underlying dimensionality to physicians' effectiveness ratings of the CAM therapies that supports the classification of these practices as either accepted or rejected.CONCLUSIONThis study provides Canadian family physicians with information concerning which CAM therapies are generally accepted by their peers as effective and which are not.

Complementary and alternative medicine use in children with asthma: prevalence and sociodemographic profile of users

Research on complementary and alternative medicine use in children with asthma is in its infancy. This study examined the prevalence, types of CAM used and sociodemographic differences in CAM use among children 5-12 years with asthma. 65% of parents reported using CAM. Usage was highest among black, poor, lesser educated parents and children with persistent symptoms. Types of CAM differed by poverty and a trend for differences by race and education emerged. Health care providers who educate themselves on CAM therapies parents use for asthma can then discuss the implications of using these therapies and potentially improve adherence to the prescribed medication regimen.

Complementary and alternative therapies: survey of knowledge and attitudes of health professionals at a tertiary pediatric/women's care facility

Nurses, physicians, and allied health professionals at the IWK Health Centre, Halifax, NS, Canada, a tertiary care, regional center for a population of 2.5 million were surveyed. We examined personal attitudes and professional practice in addressing the use of complementary and alternative medicine (CAM) use by patients. We also examined the availability of CAM-related information to health professionals. The findings suggest that health professionals: (1) are supportive of the use of selected CAM therapies by patients; (2) have almost no personal experience of CAM; (3) have limited knowledge about CAM and acquire that information mainly from the Internet, friends or family rather than professional journals; (4) are uncomfortable discussing CAM with patients and; (5) rarely or never ask patients about CAM use. We have identified barriers for health professionals to effective communication about CAM use by their patients and families. Improved access to existing policies and scientific publications, and specific continuing professional development opportunities focused on speaking openly and non-judgmentally with patients are likely to enhance accurate guidance of patients in the highly prevalent use of CAM.

Complementary and alternative medicine (CAM) for the treatment of chronic hepatitis B and C: a review

Complementary and alternative medicine (CAM) has been used for centuries in China and Japan to treat various illnesses, including viral hepatitis. Several therapeutic approaches constitute CAM, the most relevant for this review being the use of herbals. However, profound disagreements exist between conventional and alternative medicine practitioners regarding their value. Western medical advocates cite deep concerns about the purity of most herbals because of lack of standardized production, the paucity of pharmacokinetic data, the fact that few well-designed randomized, controlled trials of these products have been performed and the evidence that some herbals have been responsible for severe adverse effects. Nevertheless, many in the public, even in western countries, turn to the use of herbals, believing that they must be safe and effective because they are 'natural' and have been used for centuries, and because of dissatisfaction with conventional medicine. Accordingly, their use in western countries and the costs incurred have increased each year. While there is evidence that some herbals have physiological effects, there still is insufficient evidence to recommend their use. This paper reviews the classification, epidemiology and philosophy of CAM, and the reasons advanced for herbal use to treat viral hepatitis. The criteria necessary to develop a potential pharmacological agent are presented, as well as the requirements for conducting a scientifically valid treatment trial of herbals. Five herbals used in the past to treat viral hepatitis are reviewed and evaluated for the quality of their studies and mention is made of herbals known to have adverse effects.

The Supply of Complementary and Alternative Medicine in Swiss Hospitals

OBJECTIVES

Over the past few years, a considerable increase in complementary and alternative medicine (CAM) has been observed, particularly in primary care. In contrast little is known about the supply of CAM in Swiss hospitals. This study aims at the investigation of amount and structure of CAM activities of Swiss hospitals.

MATERIALS AND METHODS

We designed a cross-sectional survey using a 2-step, questionnaire- based approach acquiring overview information form hospital managers in a first questionnaire leading to detailed information on CAM usage at medical department level (head of department). This second questionnaire provides data of physician-based and non-physician-based CAM supply.

RESULTS

The size of hospitals was significantly associated with the provision of CAM. 33% of the hospital managers indicated 1 or more medical doctor (MD) using CAM in their hospital compared to 37% of confirmation on department level (Kappa value 0.5). Mostly different CAM methods were applied. Acupuncture was used most frequently. However only 13 hospitals (11%) occupied more than 3 CAM MDs and only 5 hospitals had more than 2 full-time equivalents for MDs. Furthermore, 74.7% of these personnel resources were dedicated for outpatient care. In terms of CAM methods anthroposophic medicine accounted for more than half of the total personnel costs. On the other hand usage of non-physician based CAM accounted for 41% according to hospital managers compared to 64% of CAM usage according to medical departments (Kappa values 0.31). Reflexology of the foot was used most frequently.

CONCLUSION

Total supply of CAM in Swiss hospitals is low and concentrates on few hospitals. Acupuncture is the widest spread discipline but anthroposophic medicine spends the most resources. The study shows that a high patient demand for CAM faces low supply in hospitals.

Efficacy of complementary and alternative medicine therapies in relieving cancer pain: a systematic review

PURPOSE

Despite widespread popular use of complementary and alternative medicine (CAM) therapies, a rigorous evidence base about their efficacy for cancer-related pain is lacking. This is a systematic review of randomized controlled trials (RCTs) evaluating CAM therapies for cancer-related pain.

METHODS

RCTs using CAM interventions for cancer-related pain were abstracted using Medline, EMBASE, CINAHL, AMED, and Cochrane database.

RESULTS

Eighteen trials were identified (eight poor, three intermediate, and seven high quality based on Jadad score), with a total of 1,499 patients. Median sample size was 53 patients, and median intervention duration was 45 days. All studies were from single institutions, four had sample size justification, and none reported any adverse effects. Seven trials reported significant benefit for the following CAM therapies: acupuncture (n = 1), support groups (n = 2), hypnosis (n = 1), relaxation/imagery (n = 2), and herbal supplement/HESA-A (n = 1, but study was of low quality without control data). Seven studies reported immediate postintervention or short-term benefit of the following CAM interventions: acupuncture (n = 2), music (n = 1), herbal supplement/Ai-Tong-Ping (n = 1), massage (n = 1), and healing touch (n = 2). Four studies reported no benefit of CAM interventions (music, n = 2; massage, n = 2) in reducing cancer pain compared with a control arm.

CONCLUSION

There is paucity of multi-institutional RCTs evaluating CAM interventions for cancer pain with adequate power, duration, and sham control. Hypnosis, imagery, support groups, acupuncture, and healing touch seem promising, particularly in the short term, but none can be recommended because of a paucity of rigorous trials. Future research should focus on methodologically strong RCTs to determine potential efficacy of these CAM interventions.

Newspaper coverage of complementary and alternative therapies for cancer—UK 2002–2004

BACKGROUND

Complementary and alternative therapies (CATs) are increasingly being used by cancer patients. These patients often rely on information retrieved from the lay press, which can affect their choices towards unconventional treatments for their disease. In this study, we aimed at assessing UK newspapers' coverage of CATs for cancer.

METHODS

The "Lexis Nexis" database was searched for 3-month periods in 2002, 2003 and 2004. The search terms were combined: "complementary OR alternative AND medicine OR therapy AND cancer". CATs were grouped and articles' contents were assessed according to predefined criteria.

RESULTS

A total of 310 articles were found: 117 came from national newspapers; 193 came from local newspaper issues. The UK press showed an increasing interest towards CATs for cancer (in 2002, 81 articles; in 2003, 82 articles and in 2004, 147 articles). The most frequently mentioned alternative therapies were diets and supplements (17.7%). Articles mainly focused on CATs as possible cancer treatments (44.8%), and 53.4% of all CATs mentioned were not backed up by trial data. The tone of the articles was generally positive towards CATs. Promotional articles increased over the years, especially for cancer centres and clinics.

CONCLUSION

UK national newspapers frequently publish articles on CATs for cancer. Much of this information seems to be uncritical with a potential for misleading patients.

The spectrum of therapeutic influences and integrative health care: classifying health care practices by mode of therapeutic action

The growing popularity of complementary and alternative medicine (CAM) and integrative medicine (IM) highlight the need for a clinically relevant system for classifying health care practices. All systems, modalities, and techniques of health care (conventional, complementary, alternative, and traditional) can be organized in categories of "primary mode of therapeutic action." This results in six categories: biochemical; biomechanical; mind-body; energy; psychological (symbolic); and nonlocal. In each category, there are subdivisions. Organizing health care by primary mode of therapeutic action has numerous benefits: (1) conventional and CAM practitioners, and the public, can readily see some of the general similarities and differences among practices; (2) health care educators gain a common foundation and shared language for explaining CAM and IM; (3) professionals and the public, wishing to combine dissimilar practices, gain a common framework for evaluating the meaning of integration; and (4) the crossover problem can be understood as a natural occurrence in health care, not a confusing intellectual dilemma. The National Center for Complementary and Alternative Medicine (NCCAM) system of categories for CAM is briefly critiqued.

Lack of standards in informed consent in complementary and alternative medicine

OBJECTIVES

To examine whether U.S.-based professional complementary and alternative medicine (CAM) organizations have explicit informed consent policies.

DESIGN AND SETTING

Phone survey conducted in July-August 2003.

RESULTS

Data were obtained from 37 out of a total of 39 eligible and accessible organizations representing 19 commonly used provider-administered CAM techniques (95% response rate.) Only 21 organizations (57%) had any informed consent policy and standards, whilst only six (16%) mandate their clinician members to routinely obtain an informed consent.

CONCLUSIONS

We found no consistent standards with respect to the practice of informed consent across a broad range of CAM practices. CAM information that is not communicated appropriately or is otherwise unavailable to patients during the decision-making process may increase the potential for healthcare oversights and adversity.

The behaviors of seeking a second opinion from other health-care professionals and the utilization of complementary and alternative medicine in gynecologic cancer patients

GOALS OF WORK

The aim of the study is to determine the predictors for seeking a second opinion and the utilization of complementary and alternative medicine (CAM) among gynecologic cancer patients.

PATIENTS AND METHODS

Patients attending a gynecologic cancer clinic of a tertiary referral center were recruited over a period of 1 year. A survey was conducted for all the participants in a one-on-one basis.

MAIN RESULTS

One hundred ninety-one patients were recruited. Eighty patients (41.9%) had consulted other health-care professionals (HCP) for a second opinion after they were diagnosed to have cancer and 89 (46.6%) had utilized CAM. In multivariate analysis, late-stage disease (OR=2.65, 95% CI 1.26-5.58), treatment with radiotherapy (OR=2.27, 95% CI 1.19-4.33) and tertiary education (OR=11.28, 95% CI 3.06-41.54) were independent predictors for seeking a second opinion from other HCP and utilization of CAM. Patients who sought a second opinion from other HCP were more likely to utilize CAM (OR=6.12, 95% CI 3.24-11.54). Eighty percent of the patients did not inform their usual caregiver their utilization of CAM.

CONCLUSIONS

Seeking a second opinion from other HCP is common in gynecologic cancer patients. Patients who seek a second opinion are more likely to utilize CAM.

Use of complementary and alternative medicine by patients with urologic cancer: a prospective study at a single Japanese institution

OBJECTIVES

We prospectively evaluated the prevalence and predictors of complementary medicine (CAM) use among Japanese patients with urologic cancer 1 year after diagnosis.

PATIENTS AND METHODS

A total of 349 patients with newly diagnosed urologic cancer answered a self-administered questionnaire on CAM use 1 year after diagnosis. General-health-related quality of life (GHQL) of the patients was also assessed at diagnosis and 1 year after diagnosis using the Medical Outcome Study Short Form-36 (SF-36). The overall prevalence, types of CAM used, and costs of CAM were assessed. The effects of several variables including GHQL at baseline and 1 year after treatment on the prevalence of use of CAM were evaluated.

RESULTS

A total of 164 respondents (47%) admitted using some type of CAM, of which 73 (45%) had used multiple types. "Health food," in particular extract from Agaricus blazei, was the most common type of CAM used. CAM users had significantly lower scores for social function, general health perception, and vitality domains than CAM non-users 1 year after diagnosis. This tendency was more marked in users of multiple types of CAM.

CONCLUSIONS

"Health food," including extract from A. blazei, was the most commonly used CAM in Japan. The prevalence of CAM use did not differ between patients with prostate cancer and those with urologic cancer other than prostate cancer. CAM users, especially those who used multiple types of CAM, had lower GHQL scores than non-users of CAM.

Use of complementary and alternative medicine among American women

INTRODUCTION AND BACKGROUND

Although women are increasingly using complementary and alternative (CAM) therapies, a national profile characterizing women who use CAM has yet to be described. The purpose of this study is to provide prevalence estimates of recent CAM use among American women and to examine sociodemographic and other characteristics associated with use.

METHODS

Data from the 1999 National Health Interview Survey are used for the analysis. Three operational definitions of recent CAM use are employed (any CAM, type-specific, and domain-specific use). All proportions and prevalence estimates are weighted and standard errors are adjusted to account for complex sample design; weighted logistic regression (with coefficient variance adjustment) is also used.

RESULTS

Overall, 33.5% of American women used CAM in the past 12 months. Spiritual healing/prayer and herbal medicine are the most commonly used, and hypnosis, biofeedback, and energy healing are the least common. Multivariate results show that women who are older, have more education, poorer health, or live in the west or midwest (versus south) are more likely to use CAM. Compared to whites, blacks, Hispanics, and Asians are less likely to use CAM. Foreign-born women, those with lower income, or who live in the Northeast are also less likely to use CAM. Insurance status is not independently associated with CAM use.

CONCLUSIONS AND DISCUSSION

This study provides one of the first comprehensive investigations of CAM use among American women. Future research examining the determinants of CAM use, incorporating attitudinal and health conditions, as well as clinical efficacy, effectiveness, and health outcome studies of specific CAM therapies are warranted.

Complementary and alternative interventions in asthma, allergy, and immunology

OBJECTIVE

To review which herbs are most commonly used as complementary and alternative medicine (CAM) for treatment of asthma, allergy, and immunologic conditions.

DATA SOURCES

A review of the literature was performed using the PubMed and OVID databases searching the keywords asthma, allergy, and CAM to identify studies published between 1980 and 2003 that focused on Echinacea (Echinacea augustifolia, Echinacea pallida, and Echinacea purpurea); garlic (Allium); angelica; chamomile; ephedra; gingko; grape seed extract; licorice root (Glycyrrhiza); St. John's wort (Hypericum); kava kava (Piper); peppermint oil and leaf (Mentha); stinging nettle (Urtica); and ginseng (Panax) published in the English and German literature.

STUDY SELECTION

Studies included in vitro and in vivo clinical trials and case reports selected according to the expert opinion of the author.

RESULTS

Echinacea is one of the most common herbs used to treat symptoms of the "common cold" or upper respiratory tract allergies. Although no common drug interactions have been reported, there is a risk of hepatotoxicity, exacerbation of allergies and asthma, and anaphylactic reactions. Garlic is primarily used for cardiovascular health and relief of cough, colds, and rhinitis. Adverse effects commonly include gastrointestinal disturbances, change in body odor through the sweat and breath, and rarely allergic reactions or hypoglycemia. Other CAM agents, including angelica, German chamomile flower, ephedra, gingko, grape seed extract, licorice root, St. John's wort, kava kava rhizome, peppermint, stinging nettle, and ginseng, are also associated with significant adverse effects.

CONCLUSION

The specialty of allergy and immunology has seen the second largest increase in the popularity of CAM (second only to practitioners who treat lower back pain). Almost all of the CAM interventions have displayed adverse effects, usually in the form of a hypersensitivity reaction. Allergists and clinical immunologists need to become more knowledgeable about CAM so that they can inform patients about the use and possible abuse of these modalities.

Use of complementary therapies among primary care clinic patients with arthritis

INTRODUCTION

Use of complementary and alternative medicine (CAM) for chronic conditions has increased in recent years. There is little information, however, on CAM use among adults with clinic-confirmed diagnoses, including arthritis, who are treated by primary care physicians.

METHODS

To assess the frequency and types of CAM therapy used by Hispanic and non-Hispanic white women and men with osteoarthritis, rheumatoid arthritis, or fibromyalgia, we used stratified random selection to identify 612 participants aged 18-84 years and seen in university-based primary care clinics. Respondents completed an interviewer-administered survey in English or Spanish.

RESULTS

Nearly half (44.6%) of the study population was of Hispanic ethnicity, 71.4% were women, and 65.0% had annual incomes of less than 25,000 dollars. Most (90.2%) had ever used CAM for arthritis, and 69.2% were using CAM at the time of the interview. Current use was highest for oral supplements (mainly glucosamine and chondroitin) (34.1%), mind-body therapies (29.0%), and herbal topical ointments (25.1%). Fewer participants made current use of vitamins and minerals (16.6%), herbs taken orally (13.6%), a CAM therapist (12.7%), CAM movement therapies (10.6%), special diets (10.1%), or copper jewelry or magnets (9.2%). Those with fibromyalgia currently used an average of 3.9 CAM therapies versus 2.4 for those with rheumatoid arthritis and 2.1 for those with osteoarthritis. Current CAM use was significantly associated with being female, being under 55 years of age, and having some college education.

CONCLUSION

Hispanic and non-Hispanic white arthritis patients used CAM to supplement conventional treatments. Health care providers should be aware of the high use of CAM and incorporate questions about its use into routine assessments and treatment planning.

Complementary and alternative medicine: impact on dentistry

Complementary and alternative medicine (CAM) represent a group of diverse medical and health care systems, practices, and products that are not considered to be part of conventional medicine. Biofeedback, acupuncture, herbal medication, massage, bioelectromagnetic therapy, meditation, and music therapy are examples of CAM treatments. Some dentists in the United States have used some of these treatments and products in their practices. Complementary medicines include herbal remedies, homeopathic medicines, and essential oils. There has been an increase in the use of herbal medicines in the US over the last 15-20 years. There is a public belief that these medicines are safe because they are made from natural sources. However, some of these products have associated adverse effects including toxicity and drug interactions. The health history taken by the dentist should include questions regarding the taking of herbal and over-the-counter medications. The dentist needs to be informed regarding the herbal and over-the-counter products that may impact the delivery of safe and effective dental treatment. In addition, the use of CAM treatments in dentistry should be based on evidence of effectiveness and safety as demonstrated in randomized clinical trials.

Complementary and alternative therapies for cancer

Many cancer patients use therapies promoted as literal alternatives to conventional medical care. Such "alternative" modalities are unproven or were studied and found worthless. These can be harmful. An even greater proportion of cancer patients uses "complementary" therapies along with mainstream cancer treatment. Most are helpful adjunctive approaches that control symptoms and enhance quality of life. This review describes alternative as well as complementary therapies commonly used today by cancer patients. Herbal remedies also are discussed. Evidence regarding the efficacy and safety of complementary/alternative medicine (CAM) is reviewed, and implications for oncologists are discussed. To encourage open communication of CAM use by patients, oncologists should be knowledgeable about the most popular remedies and know where to find reliable information for themselves and for their patients.

Use of complementary or alternative medicine in a general population in Great Britain. Results from the National Omnibus survey

BACKGROUND

A representative sample of the adults in England, Scotland and Wales was interviewed to estimate levels of use of complementary or alternative medicines (CAMs) and their socio-economic correlates.

METHODS

The Omnibus survey is a multi-purpose survey carried out in the United Kingdom by the Office for National Statistics on behalf of non-profit making organizations. The survey is carried out in 2 out of 3 months each quarter using a stratified random, probability sample of households. An eight-question module was added to the interview schedule of the survey in March 2001. Topics included practitioner-based use of 23 named CAM therapies in the past 12 months. The resulting data were analysed in conjunction with socio-economic and demographic variables.

RESULTS

A response rate of 65 per cent (1794/2761) was achieved. An estimated 10.0 per cent of the population [95 per cent confidence interval (CI) 8.7-11.5 per cent] had received any CAM therapy from a practitioner in the past year. No individual therapy was used by more than 2 per cent of the sample. An estimated 6.5 per cent (95 per cent CI 5.4-7.6) had used one of the five main therapies: acupuncture, homeopathy, chiropractic, osteopathy or herbal medicine. Estimates of CAM use were similar in England, Scotland and Wales. There was a significant positive association between CAM use and non-manual social class (p < 0.002), age left full-time education (p < 0.001), and gross income over pounds sterling 15,600 (p < 0.001). More than half (52 per cent) of the respondents that had used CAM in the past year had not told their general practitioner.

CONCLUSIONS

Strong correlations between the use of CAM and gross socio-economic indicators are demonstrated in the survey. Repeated national surveys of this type could provide a useful vehicle for collecting information about changing patterns of CAM use on a routine basis.

Complementary and alternative medicine use among adults: United States, 2002

OBJECTIVE

This report presents selected estimates of complementary and alternative medicine (CAM) use among U.S. adults, using data from the 2002 National Health Interview Survey (NHIS), conducted by the Centers for Disease Control and Prevention's (CDC) National Center for Health Statistics (NCHS).

METHODS

Data for the U.S. civilian noninstitutionalized population were collected using computer-assisted personal interviews (CAPI). This report is based on 31,044 interviews of adults age 18 years and over. Statistics shown in this report were age adjusted to the year 2000 U.S. standard population.

RESULTS

Sixty-two percent of adults used some form of CAM therapy during the past 12 months when the definition of CAM therapy included prayer specifically for health reasons. When prayer specifically for health reasons was excluded from the definition, 36% of adults used some form of CAM therapy during the past 12 months. The 10 most commonly used CAM therapies during the past 12 months were use of prayer specifically for one's own health (43.0%), prayer by others for one's own health (24.4%), natural products (18.9%), deep breathing exercises (11.6%), participation in prayer group for one's own health (9.6%), meditation (7.6%), chiropractic care (7.5%), yoga (5.1%), massage (5.0%), and diet-based therapies (3.5%). Use of CAM varies by sex, race, geographic region, health insurance status, use of cigarettes or alcohol, and hospitalization. CAM was most often used to treat back pain or back problems, head or chest colds, neck pain or neck problems, joint pain or stiffness, and anxiety or depression. Adults age 18 years or over who used CAM were more likely to do so because they believed that CAM combined with conventional medical treatments would help (54.9%) and/or they thought it would be interesting to try (50.1%). Most adults who have ever used CAM have used it within the past 12 months, although there is variation by CAM therapy.

Mental health visits to complementary and alternative medicine providers

The objective of this study was to examine the characteristics of mental health visits to Complementary and Alternative Medicine (CAM) providers. A representative sample of acupuncturists, chiropractors, massage therapists, and naturopathic physicians in four states reported on 8933 consecutive visits, including demographic characteristics; presenting complaints; referral source; treatments provided; disposition; and other sources of care for the presenting problem. The proportion of visits for a mental health complaint ranged from 7% to 11% for acupuncture, massage, and naturopathic physicians to less than 1% for chiropractors. For acupuncturists, massage therapists, and naturopaths, 69-87% of patients making mental health visits were self-referred. The CAM provider discussed care with a conventional medical provider in 6-20% of cases and was aware of concomitant conventional medical care in an additional 10-30%. Only 1-5% were subsequently referred to conventional providers. For acupuncturists, massage therapists, and naturopaths, the proportion of visits for mental health concerns is similar to that in conventional primary care. Mental health visits to chiropractors are much less common, but this may reflect differences in true prevalence or differences in presentation. Among those seeking CAM care for mental disorders, concomitant treatment by conventional medical providers is common, but communication or coordination of care is rare.

Why physicians need to look more closely at the use of complementary and alternative medicine by multiple sclerosis patients

With the aim of contributing to the knowledge of attitudes, patterns and motivations for the use of complementary and alternative medicine (CAM) for multiple sclerosis (MS), 109 MS outpatients, or their close relative in cases of mental status impairment, were interviewed using a semi-structured questionnaire. The main results are: (i). 35.7% used at least one CAM at least once; (ii). homeopathy and diets were the most common; (iii). 39.4% showed a positive attitude towards CAM; (iv). a perceived benefit was recorded in 61.5% of cases; (v). the referral source was a physician in only 12.8% of cases; (vi). caring neurologist was not consulted in 82% and generalist was not consulted in 67% of cases; (vii). of 61 CAM interventions, 21 were expected to be disease-modifying and 40 symptomatic; (viii). CAM negatively influenced compliance with conventional medical management in very few cases (2/39); (ix). a higher expanded disability status scale (EDSS) was observed in CAM users; and (x). in those who used CAM during last 3 years (21.1%), the approximate mean cost per year per person was 483 euro. In Italy, the use of CAM in MS is widespread but costly. This study has provided further baseline data on which to assess trends in CAM use and has highlighted issues for patients and conventional doctors about the use of CAM to deal with health problems. More research into the implications of concurrent use of CAM with conventional medicine on public health care is required.

Complementary and conventional medicine: a concept map

BACKGROUND

Despite the substantive literature from survey research that has accumulated on complementary and alternative medicine (CAM) in the United States and elsewhere, very little research has been done to assess conceptual domains that CAM and conventional providers would emphasize in CAM survey studies. The objective of this study is to describe and interpret the results of concept mapping with conventional and CAM practitioners from a variety of backgrounds on the topic of CAM.

METHODS

Concept mapping, including free sorts, ratings, and multidimensional scaling was used to organize conceptual domains relevant to CAM into a visual "cluster map." The panel consisted of CAM providers, conventional providers, and university faculty, and was convened to help formulate conceptual domains to guide the development of a CAM survey for use with United States military veterans.

RESULTS

Eight conceptual clusters were identified: 1) Self-assessment, Self-care, and Quality of Life; 2) Health Status, Health Behaviors; 3) Self-assessment of Health; 4) Practical/Economic/ Environmental Concerns; 5) Needs Assessment; 6) CAM vs. Conventional Medicine; 7) Knowledge of CAM; and 8) Experience with CAM. The clusters suggest panelists saw interactions between CAM and conventional medicine as a critical component of the current medical landscape.

CONCLUSIONS

Concept mapping provided insight into how CAM and conventional providers view the domain of health care, and was shown to be a useful tool in the formulation of CAM-related conceptual domains.

Complementary and alternative medicine: personal preference or low cost option?

From acupuncture to yoga, Americans' use of complementary and alternative medicine (CAM) is widespread and growing. The reasons that people give for using CAM are as diverse as the CAM therapies themselves: some perceive that conventional health care is ineffective, while others consider CAM to be more consistent with their own values and beliefs about health. As conventional health care costs rise, it is also possible that some people turn to CAM as a low cost alternative. This Issue Brief summarizes research that evaluates the relationship between CAM use and perceived access to conventional health care.

The use of complementary and alternative therapies by people with multiple sclerosis

Complementary and alternative medicine (CAM) refers to therapeutic approaches not considered part of conventional medicine. A survey was mailed to sample of patients with multiple sclerosis (MS). The response rate was 440/673 (65%). Mean sample age was 48 years; 75% were female. Respondents ranged from mildly to severely impaired. Seventy percent used CAM primarily to improve health and manage the symptoms of MS. Most consumers reported positive effects. Lack of knowledge was the most common reason given for not using CAM. Patient education, physician-patient dialogue, and continued research and regulation of CAM are important to the well being of CAM consumers.

Assessing alternative medicine: methodological and research policy concerns

OBJECTIVES

Setting funding priorities among research projects for complementary and alternative therapies is especially vulnerable to arbitrary, partisan criteria and opportunistic readings of controversial evidence. This study develops a procedural approach to characterizing, in a transparent and even-handed way, the available evidence on these treatments and demonstrates a simple analytical scheme for prioritizing competing, but typically incommensurable, research projects for public support.

METHODS

A simple five-step scheme for categorizing therapies is developed and justified, based on a taxonomy of the study designs used to generate research evidence. Once identified, candidate therapies are assigned to ordered categories along these design criteria and effectively grouped into equivalence classes by type of evidence. Finally, a partial ordering on the therapies is formed within each class by means of secondary screening criteria.

RESULTS

Twenty-five candidate therapies are assigned to equivalence classes. The intent, in effect, is to restrict comparisons to those therapies that fall within a particular class of similar study designs. Within-class orderings avoid the problem of having better-known or better-supported therapies crowd out lesser known ones when it comes to allocating dollars for more research. A set of criteria and procedure for prioritizing spending for further research is demonstrated.

CONCLUSIONS

Relying on an open, formal procedure for comparing unconventional therapies offers protection against prejudgment in setting funding priorities, especially when weak clinical evidence relates more to a low investment in research than lack of efficacy.

Use of and attitudes toward complementary and alternative medicine among family practice patients in small rural Illinois communities

CONTEXT

Complementary and alternative medicine (CAM) use continues to increase in the United States. Data on rural patients' use and extent of integration of CAM with conventional medicine are lacking, although this is a population often associated with use of "folk remedies" and self-care strategies.

PURPOSE

To examine rural primary care patients' attitudes toward and use of CAM.

METHODS

A total of 176 surveys (70% response rate) were returned by patients at 5 geographically dispersed, rural Illinois family practice clinics to examine rural patients' use of, attitudes toward, and experiences with alternative medicine and providers.

FINDINGS

Nearly two thirds of patients reported use of alternative medicine. Therapies most often used were vitamins/megavitamins, chiropractic, relaxation, and prayer/faith healing. Rural patients with more medical problems and a higher level of education were more likely to use alternative techniques. Three fifths of the patients felt that their doctor should discuss alternative medicine and therapies with them.

CONCLUSIONS

Physician understanding and communication regarding CAM may be especially important in rural areas, where access to care is more limited and where there is greater reliance on the primary care physician as a "gatekeeper" for patient health.

A philosophical analysis of the evidence-based medicine debate

BACKGROUND

The term "evidence-based medicine" (or EBM) was introduced about ten years ago, and there has been considerable debate about the value of EBM. However, this debate has sometimes been obscured by a lack of conceptual clarity concerning the nature and status of EBM.

DISCUSSION

First, we note that EBM proponents have obscured the current debate by defining EBM in an overly broad, indeed almost vacuous, manner; we offer a clearer account of EBM and its relation to the alternative approaches to medicine. Second, while EBM proponents commonly cite the philosophical work of Thomas Kuhn and claim that EBM is a Kuhnian 'paradigm shift,' we argue that such claims are seriously mistaken and unduly polarize the EBM debate. Third, we suggest that it is much more fruitful to understand the relationship between EBM and its alternatives in light of a different philosophical metaphor: W.V. Quine's metaphor of the web of belief. Seen in this way, we argue that EBM is an approach to medical practice that is indeed importantly different from the alternatives.

SUMMARY

We can have a more productive debate about the value of EBM by being clearer about the nature of EBM and its relationship to alternative approaches to medicine.
