BackgroundHealth care providers are often ill prepared to interact about or make acceptable conclusions on complementary and alternative medicine (CAM) despite its widespread use. We explored the knowledge, attitudes, and practices of health care providers regarding CAM.MethodsThis cross-sectional study was conducted between March 1 and July 31, 2015 among health care providers working mainly in the public sector in Trinidad and Tobago. A 34-item questionnaire was distributed and used for data collection. Questionnaire data were analysed using inferential and binary logistic regression models.ResultsResponse rate was 60.3% (362/600). Responders were 172 nurses, 77 doctors, 30 pharmacists, and 83 other health care providers of unnamed categories (mainly nursing assistants). Responders were predominantly female (69.1%), Indo-Trinidadian (55.8%), Christian (47.5%), self-claimed “very religious” (48.3%), and had <5 years of working experience (40.6%). The prevalence of CAM use was 92.4% for nurses, 64.9% for doctors, 83.3% for pharmacists, and 77.1% for other health care providers. The majority (50–75%) reported fair knowledge of herbal, spiritual, alternative, and physical types of CAM, but had no knowledge of energy therapy and therapeutic methods. Sex, ethnicity, and type of health care provider were associated with both personal use and recommendation for the use of CAM. Predictors of CAM use were sex, religion, and type of health care provider; predictors of recommendation for the use of CAM were sex and type of health care provider. About half of health care providers (51.4%) and doctors (52%) were likely to ask their patients about CAM and <15% were likely to refer patients to a CAM practitioner. However, health care providers expressed interest in being educated on the subject. Doctors (51.9%) and pharmacists (63.3%) said that combination therapy is superior to conventional medicine alone. Less than 10% said conventional medicine should be used alone.ConclusionKnowledge about CAM is low among health care providers. The majority engages in using CAM but is reluctant to recommend it. Predictors of CAM use were sex, religion, and profession; predictors of recommendation for the use of CAM were sex and profession. Health care providers feel the future lies in integrative medicine.

“…Nonconventional (i.e. traditional) medicine has been used in Trinidad for centuries [ 19 ] and includes ‘home medication/remedies’ and unconventional medical practices [ 20 ]. For decades, CAM [ 3 ] was the major (and sometimes only) form of medical treatment available in Trinidad [ 21 ].…”

Use of complementary and alternative medicine by patients with end-stage renal disease on haemodialysis in Trinidad: A descriptive study

2017

BackgroundDespite the paucity of scientific evidence, complementary and alternative medicine (CAM) is widely used for the prevention and treatment of illness, holistic care, and counteracting the adverse effects of conventional medicine (CM). This study investigates the use of CAM by patients with end-stage renal disease (ESRD) on haemodialysis.MethodsThis quantitative study was conducted from November 1, 2014 to December 31, 2014 in the haemodialysis unit at San Fernando General Hospital (San Fernando, Trinidad). Face-to-face questionnaire-based interviews were held with101of 125 eligible patients (response rate, 80.5%) at the chairside during haemodialysis. The completed questionnaires were entered into a secure computer database. Data analysis included descriptive analysis, χ2 tests, and binary logistic regression analysis.ResultsA minority of the patients were CAM users (n = 19; 18.8%). All 19 CAM users took medicinal herbs, 78.9% (n = 15) used spiritual therapy, and 10.5% (n = 2) used alternative systems. Medicinal tea (n = 15; 78.9%), garlic (Allium sativum) (n = 17; 73.7%), and ginger (Zingiber officinale roscoe) (n = 13; 68.4%) were the most commonly used medicinal herbs. Seven (36.8%) patients used Chinese herbal medicines and 3 (15.8%) patients used Aloe vera. All CAM users were willing to use CAM without supervision or monitoring by their doctors while receiving CM. The use of CAM could not be predicted by age, sex, ethnicity, education, religion, marital status, or employment. Nearly all (98%) patients were satisfied with CAM. More than one-third (36.8%) of patients did not disclose their use of CAM to their doctors, who were generally indifferent to such therapy.ConclusionsThe use of CAM by patients with ESRD was relatively infrequent. All patients used medicinal herbs, most patients used spiritual therapy, and a minority of patients used alternative systems. Complementary and alternative medicine was primarily used for spiritual reasons and the likelihood of its use was influenced by family, friends, and other patients. Patients continued using CM with one or more CAM therapies without informing their healthcare providers, which is a major health risk.

“…Trinidad’s traditional medicine (nonconventional indigenous medical practices) [ 21 ] and home medication/remedies [ 22 , 23 ] have been in use by Amerindians (e.g. Tainos and Kalinagos), Afro-Trinidadians, and Indo-Trinidadians for centuries, and are still used in part due to the lack of available conventional health care [ 24 ] and the influence of positive testimonies and perceived benefits.…”

Prevalence, patterns, and perceived value of complementary and alternative medicine among HIV patients: a descriptive study

2017

BackgroundUse of complementary and alternative medicine (CAM) is widespread among different patient populations despite the availability of evidence-based conventional medicine and lack of supporting evidence for the claims of most CAM types. This study explored the prevalence, patterns, and perceived value of CAM among human immunodeficiency virus (HIV) patients.MethodsThis quantitative descriptive study was conducted between November 1, 2014 and March 31, 2015 among a cross-sectional, convenience sample of attendees of the HIV clinic of a public tertiary health care institution. Face-to-face interviews using a 34-item questionnaire were conducted. Data analysis included descriptive statistics, chi-square tests, and binary logistic regression analysis.ResultsCAM was used by 113 (32.8%) of a total of 343 HIV patients, but <1% informed their health care providers of CAM usage. Medicinal herbs were the most common type of CAM used (n = 110, 97.3%) followed by spiritual therapy (n = 56, 49.6%), including faith healing/prayer and meditation. The most used medicinal herbs were Aloe vera (n = 54, 49.1%), ginger (n = 33, 30.0%), and garlic (n = 23, 20.9%). The most used vitamins were complex B vitamins (n = 70, 61.9%), followed by vitamin A (n = 58, 51.3%), vitamin E (n = 51, 45.1%), and vitamin D (n = 42, 37.1%). Most CAM users continued using conventional medicine in addition to CAM and were willing to use CAM without supervision and without informing their health care provider. Patients were generally satisfied with CAM therapy (n = 91, 80.5%). The main reasons for CAM use were the desire to take control of their treatment (8.8%) or just trying anything that could help (18.8%). Main influences were the mass media (32.7%) and non-hospital health personnel (19.5%). Predictors of CAM use were being 30–50 years, married and having a secondary school education.ConclusionAbout one-third of HIV patients used CAM, but virtually none informed their healthcare provider. Medicinal herbs were the most common type of CAM, followed by spiritual therapy and vitamins. A patient’s decision to use CAM was influenced for the most part by the mass media and non- hospital health care personnel.
