Potential factors that influence usage of complementary and alternative medicine worldwide: a systematic review.

ABSTRACT: OBJECTIVES:To determine similarities and differences in the reasons for using or not using complementary and alternative medicine (CAM) amongst general and condition-specific populations, and amongst populations in each region of the globe. METHODS:A literature search was performed on Pubmed, ScienceDirect and EMBASE. KEYWORDS:'herbal medicine' OR 'herbal and dietary supplement' OR 'complementary and alternative medicine' AND 'reason' OR 'attitude'. Quantitative or qualitative original articles in English, published between 2003 and 2018 were reviewed. Conference proceedings, pilot studies, protocols, letters, and reviews were excluded. Papers were appraised using valid tools and a 'risk of bias' assessment was also performed. Thematic analysis was conducted. Reasons were coded in each paper, then codes were grouped into categories. If several categories reported similar reasons, these were combined into a theme. Themes were then analysed using ?2 tests to identify the main factors related to reasons for CAM usage. RESULTS:231 publications were included. Reasons for CAM use amongst general and condition-specific populations were similar. The top three reasons for CAM use were: (1) having an expectation of benefits of CAM (84% of publications), (2) dissatisfaction with conventional medicine (37%) and (3) the perceived safety of CAM (37%). Internal health locus of control as an influencing factor was more likely to be reported in Western populations, whereas the social networks was a common factor amongst Asian populations (p < 0.05). Affordability, easy access to CAM and tradition were significant factors amongst African populations (p < 0.05). Negative attitudes towards CAM and satisfaction with conventional medicine (CM) were the main reasons for non-use (p < 0.05). CONCLUSIONS:Dissatisfaction with CM and positive attitudes toward CAM, motivate people to use CAM. In contrast, satisfaction with CM and negative attitudes towards CAM are the main reasons for non-use.

Project description:BackgroundOut-of-pocket expenditures of over 34 billion dollars per year in the US are an apparent testament to a widely held belief that complementary and alternative medicine (CAM) therapies have benefits that outweigh their costs. However, regardless of public opinion, there is often little more than anecdotal evidence on the health and economic implications of CAM therapies. The objectives of this study are to present an overview of economic evaluation and to expand upon a previous review to examine the current scope and quality of CAM economic evaluations.MethodsThe data sources used were Medline, AMED, Alt-HealthWatch, and the Complementary and Alternative Medicine Citation Index; January 1999 to October 2004. Papers that reported original data on specific CAM therapies from any form of standard economic analysis were included. Full economic evaluations were subjected to two types of quality review. The first was a 35-item checklist for reporting quality, and the second was a set of four criteria for study quality (randomization, prospective collection of economic data, comparison to usual care, and no blinding).ResultsA total of 56 economic evaluations (39 full evaluations) of CAM were found covering a range of therapies applied to a variety of conditions. The reporting quality of the full evaluations was poor for certain items, but was comparable to the quality found by systematic reviews of economic evaluations in conventional medicine. Regarding study quality, 14 (36%) studies were found to meet all four criteria. These exemplary studies indicate CAM therapies that may be considered cost-effective compared to usual care for various conditions: acupuncture for migraine, manual therapy for neck pain, spa therapy for Parkinson's, self-administered stress management for cancer patients undergoing chemotherapy, pre- and post-operative oral nutritional supplementation for lower gastrointestinal tract surgery, biofeedback for patients with "functional" disorders (eg, irritable bowel syndrome), and guided imagery, relaxation therapy, and potassium-rich diet for cardiac patients.ConclusionWhereas the number and quality of economic evaluations of CAM have increased in recent years and more CAM therapies have been shown to be of good value, the majority of CAM therapies still remain to be evaluated.

Project description:IntroductionPremature ejaculation (PE) is defined as ejaculation within 1 minute (lifelong PE) or 3 minutes (acquired PE), inability to delay ejaculation, and negative personal consequences. Management includes behavioral and pharmacologic approaches.AimTo systematically review effectiveness, safety, and robustness of evidence for complementary and alternative medicine in managing PE.MethodsNine databases including Medline were searched through September 2015. Randomized controlled trials evaluating complementary and alternative medicine for PE were included.Main outcome measuresStudies were included if they reported on intravaginal ejaculatory latency time (IELT) and/or another validated PE measurement. Adverse effects were summarized.ResultsTen randomized controlled trials were included. Two assessed acupuncture, five assessed Chinese herbal medicine, one assessed Ayurvedic herbal medicine, and two assessed topical "severance secret" cream. Risk of bias was unclear in all studies because of unclear allocation concealment or blinding, and only five studies reported stopwatch-measured IELT. Acupuncture slightly increased IELT over placebo in one study (mean difference [MD] = 0.55 minute, P = .001). In another study, Ayurvedic herbal medicine slightly increased IELT over placebo (MD = 0.80 minute, P = .001). Topical severance secret cream increased IELT over placebo in two studies (MD = 8.60 minutes, P < .001), although inclusion criteria were broad (IELT < 3 minutes). Three studies comparing Chinese herbal medicine with selective serotonin reuptake inhibitors (SSRIs) favored SSRIs (MD = 1.01 minutes, P = .02). However, combination treatment with Chinese medicine plus SSRIs improved IELT over SSRIs alone (two studies; MD = 1.92 minutes, P < .00001) and over Chinese medicine alone (two studies; MD = 2.52 minutes, P < .00001). Adverse effects were not consistently assessed but where reported were generally mild.ConclusionThere is preliminary evidence for the effectiveness of acupuncture, Chinese herbal medicine, Ayurvedic herbal medicine, and topical severance secret cream in improving IELT and other outcomes. However, results are based on clinically heterogeneous studies of unclear quality. There are sparse data on adverse effects or potential for drug interactions. Further well-conducted randomized controlled trials would be valuable.

Project description:BackgroundBronchiolitis is a common cause of hospitalization among infants. The limited effectiveness of conventional medication has prompted the use of complementary and alternative medicine (CAM) as alternative or adjunctive therapy for the management of bronchiolitis.AimsTo determine the effectiveness and safety of CAM for the treatment of bronchiolitis in infants aged less than 2 years.MethodsA systematic electronic search was performed in Medline, Embase, CINAHL, AMED, and Cochrane Central Register of Controlled Trials (CENTRAL) from their respective inception to June 30, 2016 for studies evaluating CAM as an intervention to treat bronchiolitis in infants (1 month to 2 years of age). The CAM could be any form of treatment defined by the National Center for Complementary and Integrative Health (NCCIH) and was utilized either as a single agent or adjunctive therapy. The predefined primary outcome was length of hospital stay. Secondary outcomes were time to resolution of bronchiolitis symptoms, adverse events, and all other clinical outcomes reported by the included studies.ResultsThe review identified 11 studies (8 randomized controlled trials and 3 cohort studies) examining four herbal preparations and four supplements used either as adjunctive or alternative therapy for bronchiolitis in 904 infants. Most studies were of moderate quality. Among six studies reporting on length of stay, a significant benefit was found for Chinese herbal medicine compared to ribavirin in one cohort study (n = 66) and vitamin D compared to placebo in one randomized controlled trial (n = 89). Studies of Chinese herbal medicine (4 studies, n = 365), vitamin D (1 study, n = 89), N-acetylcysteine (1 study, n = 100), and magnesium (2 studies, n = 176) showed some benefits with respect to clinical severity scores, oxygen saturation, and other symptoms, although data were sparse for any single intervention and the outcomes assessed and reported varied across studies. Only five studies reported on adverse events; no serious adverse events were reported.ConclusionsAmong 11 studies examining the effect of CAM on inpatients with bronchiolitis, six reported on the review's primary outcome of length of hospital stay. In general, findings did not show a significant benefit associated with the primary outcome. Preliminary evidence indicated that Chinese herbal medicine mixtures, vitamin D, N-acetylcysteine, and magnesium might be useful in managing the symptoms of bronchiolitis. However, the evidence was not sufficient or rigorous enough to formulate recommendations for the use of any CAM. Among studies that reported adverse events, no serious harms were noted.

Project description:Objectives: Complementary and alternative medicine (CAM) has become increasingly popular among cancer patients and is often used concomitantly with standard cancer therapies. Nonetheless, disclosure of CAM utilization by cancer patients to physicians, along with the provision of information on CAM therapies by physicians, is poor. This review explores the literature to synthesize existing information on communication about CAM usage, reasons for nondisclosure, and the clinical implications thereof. Methods: A search of medical literature published between December 1, 2009, and October 1, 2021 (last searched on April 18, 2022), on communications between physicians and cancer patients about CAM treatments was conducted through MEDLINE and EMBASE. Results were screened for inclusion, dually reviewed, and assessed using the QualSyst quality appraisal instrument. Findings were categorized and synthesized for review. Results: A total of 30 articles were located (n = 8721 total participants), which discussed elements related to patient disclosure of CAM use (n = 16), provider experiences or perceptions related to communication about CAM (n = 3), patterns of this communication (n = 6), and recommendations for effectively discussing CAM with cancer patients (n = 5). Reports indicate that nondisclosure is common throughout the cancer care spectrum. Factors influencing nondisclosure range from patient beliefs and attitudes about their provider, demographic characteristics, disease progression, physician-patient relationship, physician noninquiry, and type of CAM used; ultimately creating a gap in care that may have serious medical implications. Discussion: Many of the studies identified are small and confined to a single-center, hospital-network, or geographic setting, thereby limiting the applicability of findings and recommendations. Nonetheless, improving patient-physician communication is essential in delivering evidence-informed, patient-centered care and crucial for achieving patient satisfaction and positive health outcomes. The lack of adequate CAM dialogue about CAM use increases the risk of adverse interactions with conventional cancer treatments and results in missed opportunities for providers and patients to engage in vital information exchange. Future research and education are necessary to further identify barriers surrounding patient-provider communication about CAM treatments.
