A cross-sectional study of provider and patient characteristics associated with outpatient disclosures of dietary supplement use

Fulminant Red Yeast Rice-Associated Rhabdomyolysis with Acute Liver Injury and Hyperkalemia Treated with Extracorporeal Blood Purification Using CytoSorb

Rhabdomyolysis is a pathophysiological process characterized by the destruction of muscle cells and the release of intracellular contents into the systemic circulation, which can lead to acute kidney injury (AKI) and failure. Causes are classified mainly as traumatic and non-traumatic, with statin-induced rhabdomyolysis being widely recognized. Other causes are seldomly reported, one being red yeast rice (RYR) or its active ingredient, monacolin K. We present a life-threatening case of fulminant rhabdomyolysis with severe hyperkalemia, accompanied by ECG changes, tetraparesis, impending compartment syndrome, and liver injury requiring intensive care treatment. Prompt renal replacement therapy was commenced, initially for the treatment of hyperkalemia and subsequently for myoglobin adsorption using the CytoSorb membrane. High doses of corticosteroids were administered as the trigger factor was initially unknown. The condition gradually improved, and the patient regained full functionality. The diagnosis of toxic rhabdomyolysis was confirmed only after the patient was discharged from the intensive care unit. An over-the-counter supplement containing red yeast rice (RYR) was identified as the sole possible triggering factor, with symptoms occurring two days after beginning the self-treatment.

Why patients fail to seek information on OTC product interactions with a direct-acting oral anticoagulant: perspectives on information-seeking

BACKGROUND

Many patients taking direct-acting oral anticoagulants (DOACs) also consume over-the-counter (OTC) products (dietary supplements and OTC medications), yet many lack knowledge of potential interactions that may increase or decrease DOAC efficacy and may not seek information about OTC products. The objective of this study was to describe patient attitudes and beliefs that inhibited information seeking about potential apixaban-OTC product interactions.

METHODS

Participants included English-, Spanish-, Mandarin-, and Cantonese-speaking adults from two large academic medical centers who reported taking apixaban (a frequently prescribed DOAC) in the past month. Thematic analysis was performed on semi-structured interviews.

RESULTS

Sixty patients aged 24-93 years (mean = 65.3; SD = 15.6) were interviewed; 55% were women. Participants took a total of 236 OTC products. Those with potential interactions with apixaban warranting consideration for therapy modification included: ibuprofen (n = 14; 5.9%), aspirin (n = 8; 3.4%), and naproxen (n = 3; 1.3%). Interviews revealed 5 major themes related to a lack of information-seeking about OTC products: (1) patients lack awareness of the potential for interactions; (2) patients believe that OTC products are safe and/or regulated (largely because they were familiar with the products, had previously taken them, or assumed that dietary supplements were regulated by the Food and Drug Administration); (3) patients believe that providers are responsible for alerting patients about potential interactions (as patients assumed that providers were aware of their OTC product use); (4) patients had prior knowledge of and/or used OTC products infrequently; and (5) obtaining information can be inconvenient. Inquiries regarding preferred information sources revealed 59 (98.3%) patients most frequently sought or would seek information from physicians and 34 (56.7%) from the internet.

CONCLUSIONS

Patients taking apixaban raised reasons for not seeking information about potential OTC product interactions that included poor awareness, perceptions regarding the safety of OTC products, and beliefs in provider responsibility for informing them about interactions. Greater patient education is needed regarding the potential for OTC product-DOAC interactions and the regulation of OTC products, particularly dietary supplements.

Exploring GP and patient attitudes towards the use and deprescribing of dietary supplements: a survey study in Switzerland

BACKGROUND

Dietary supplements are commonly used by older adults, but their inappropriate use may lead to adverse events. To optimise medication use, general practitioners (GPs) ideally are aware of all substances that patients use, including supplements. This cross-sectional study explored the use of dietary supplements by older patients with polypharmacy, the rate at which they disclosed this use to their GPs, and compared patients' and GPs' attitudes towards discontinuing dietary supplements.

METHODS

Ten GPs in Swiss primary care recruited five to ten of their older patients taking ≥ 5 regular medications. Both GPs and their patients completed a survey on patients' use of dietary supplements and attitudes towards deprescribing those. We described and compared their responses. We assessed the association of supplement disclosure with patient characteristics using multilevel logistic regression analysis.

RESULTS

Three out of ten GPs (30%) were female, and GPs' average age was 52 years (SD = 8). 45% of patients were female (29/65). Most patients (n = 45, 70%) were taking ≥ 1 supplement. On average, patients reported to be using three supplements (SD = 2). In 60% (n = 39) of patients, GPs were unaware of ≥ 1 supplement used. We did not find evidence for an association between supplement disclosure to GPs and patient characteristics. Only 8% (n = 5) of patients and 60% (n = 6) of GPs reported ≥ 1 supplement they would be willing to deprescribe and none of the supplements reported by GPs and patients to deprescribe matched.

CONCLUSION

Swiss GPs were unaware of many dietary supplements used by their older patients, which may affect medication optimisation efforts.

Varieties of silence - a mixed-methods study exploring reasons and justifications for nondisclosure of the use of complementary therapies to physicians in Finland

BACKGROUND

In health care, two in three users of complementary therapies (CT) stay silent about their CT use. Disclosure of CT use to physicians is important for patient safety, participation, and shared decision-making. Common reasons for CT nondisclosure include patients´ expectations of physicians' unaccepting response to disclosure, physicians not asking, and patients believing it is unnecessary. This study aimed to increase understanding of patient silence. We investigated how the reasons for nondisclosure of CT use reported by CT users were associated with the frequency of CT disclosure and how these associations and reported justifications to keep silent reflect patient silence among the study participants.

METHODS

This mixed-methods study used existing data from the non-probability-based online survey (n = 6802) targeted to CT users among the general population in Finland. A qualitative structured tabular thematic analysis was conducted for the selected 342 brief texts describing the reasons and justification for not telling physicians about CT use. The associations between the frequency of CT disclosure and the reasons for CT nondisclosure were analysed by crosstabulations and binary logistic regression analysis with SPSS (v28).

RESULTS

Three types of patient silence were revealed. Avoidant silence illustrates the respondents coping with the fear of unwanted response from a physician and avoiding the expected negative consequences of CT disclosure. Precautionary silence exemplifies respondents striving to prevent the reoccurrence of previously experienced frustration of wishes to be seen and heard as CT users. Conditional silence portrays the self-confidence of respondents who assessed their need to disclose CT use to physicians on a case-by-case basis.

CONCLUSIONS

Silence, for some patients, may serve as a way of warding off past and possible future fears and frustrations related to CT disclosure. It is important to recognise different types of patient silence related to CT disclosure to enhance patient participation and shared decision-making in health care. Efforts are needed to provide health policy decision-makers with information about CT users' lived experiences with CT communication in health care.

Quantity, Duration, Adherence, and Reasons for Dietary Supplement Use among Adults: Results from NHANES 2011-2018

Dietary supplement use is common among US adults. We aimed to investigate the quantity, duration, adherence, and reasons for supplement use in individuals who take supplements. Data from 2011 to 2018 from the National Health and Nutrition Examination Survey (NHANES) dataset were analyzed. Four cycles of data were combined to estimate these outcomes. Results are presented as overall group and by subgroups. All analyses were weighted to be nationally representative. The Taylor Series Linearization approach was used to generate variance estimates. A total of 12,529 participants were included. Over 70% of these individuals reported taking more than one unit of dietary supplements daily. Notably, approximately 40% had been taking supplements for more than five years and about 67% were highly adherent to at least one supplement. However, only 26.9% of these supplements were taken following a doctor's recommendation. The primary reasons for dietary supplements intake included improving overall health (37.2%), maintaining health (34.7%), bone health (21.4%), and diet supplementation (20.3%). Our findings indicate that most participants proactively used multiple dietary supplements focused on self-managed health and prevention, with substantial dedication to long-term use and high adherence. Healthcare professionals should play a more active role in guiding such behaviors to optimize the health outcomes of dietary supplement users across the United States.

Beliefs, Experiences, and Openness Regarding Dietary Interventions: Data From an Urban Hispanic Population With Rheumatic Disease in the US

OBJECTIVE

To obtain descriptive data on the beliefs, behaviors, and openness regarding dietary changes for rheumatic diseases in an urban US Hispanic patient population with rheumatic disease as foundational data for future intervention design.

METHODS

We distributed a voluntary survey to our primarily Hispanic population at an outpatient rheumatology clinic for 19 weeks. This survey queried individuals' behaviors as they related to dietary intake used for the treatment of rheumatic disease, perceptions of the effect of food groups on rheumatic disease activity, barriers to physician-recommended diets, and willingness to try future interventions. We used descriptive statistics and Pearson's chi-square test to evaluate associations.

RESULTS

More than 40% of survey respondents from our primarily (88%) Hispanic population noted a link between what they ate and their underlying rheumatic disease activity. More than one-third of patients had, at some point, modified dietary intake to affect their rheumatic disease. Vegetables, fruit, and white meats were commonly reported to improve disease, while red meat and processed foods were reported to worsen disease. Barriers to following a prespecified diet included cost and lack of knowledge. More than 70% of respondents indicated willingness to attempt certain eating patterns should it help their underlying rheumatic disease.

CONCLUSION

In this primarily Hispanic rheumatic disease patient population, many have not only noted a correlation between dietary intake and rheumatic disease activity but are also open to future nutrition-related interventions. As this population experiences poor rheumatic disease outcomes and a high rate of lifestyle-related comorbidities, an intervention to optimize healthy eating patterns would likely be beneficial as well as acceptable.

Association between experience of interprofessional care and self-medication among family caregivers: A cross-sectional study

BACKGROUND

Although healthcare professionals pay attention to the drugs prescribed by physicians, few studies have assessed self-medication by family caregivers. Family caregivers' experience of interprofessional care in the care of patients can influence caregivers' health behaviors.

OBJECTIVES

This study aimed to describe self-medication among family caregivers of community-dwelling adult patients, and to assess association between family caregivers' experience of interprofessional care and their self-medication, adjusting for possible confounding factors.

METHODS

We conducted a cross-sectional survey from November to December 2020 in Ibaraki Prefecture, Japan. Family caregivers between 40 and 74 years old and caring for community-dwelling adult patients with chronic conditions were recruited. The use of any self-medication in the last 2 weeks by family caregivers was the outcome variable. The explanatory variable was family caregivers' experience of interprofessional care in the care of patients, using the Japanese version of the Caregivers' Experience Instrument (J-IEXPAC CAREGIVERS). Adjusted covariates were age, gender, educational attainment, annual household income, self-rated health, and caregiving time of family caregivers.

RESULTS

Of 1091 recruited family caregivers, 750 were included in the analysis. A total of 258 (34.4%) family caregivers reported having used self-medication in the past 2 weeks. Logistic regression analysis showed that having a higher score on the J-IEXPAC CAREGIVERS (odds ratio 0.80 per 1 standard deviation increase) was associated with less use of self-medication by caregivers.

CONCLUSIONS

This study revealed that about one-third of family caregivers self-medicate, and this practice is associated with a less positive experience of interprofessional care. These results suggest that it is important for healthcare professionals to be aware of the health condition of family caregivers and to provide appropriate advice regarding self-medication.

Complementary and Integrative Medicine: Origins and Expanding Horizons

This article is an introduction to the concepts of complementary, alternative, and integrative medicine. It discusses the scope and prevalence of complementary and integrative medicine (CIM) use among otolaryngology patients. Specific types of CIM are characterized in the context of their origins, philosophic and historical bases, scientific evidence, and applicability to the practice of otolaryngology. The author's intent is to provide a framework for discussing CIM with patients and integrate into treatment paradigms in an evidence-based manner.

Patient Perspectives on the Development of a Novel Mobile Health (mHealth) Application for Dietary Supplement Tracking and Reconciliation – A Qualitative Focus Group Study

Background: More than 170 million adults use dietary supplements (DS) in the United States, which can have both benefit and harm to patient health. DS use is often poorly documented in the medical record and can pose health risks if not properly communicated with providers. Reasons for poor DS documentation include low disclosure rates, time constraints of clinical encounters, and providers’ failure to inquire about DS use. This study was conducted to assess patients’ views on the facilitators and barriers to using a mobile health (mHealth) application (app) to collect and share DS information with their healthcare providers. Methods: Utilizing a theory-based conceptual model, we conducted seven patient focus groups (FGs) to assess opinions on DS safety, provider communication, comfort with technology use, and our proposed mHealth app. Participants were recruited from the general public and through patient advisory groups. Patient views will inform the creation of an mHealth app to improve DS patient-provider communication and tracking and reconciliation in the electronic medical record (EMR). Results: Overall, participants believe their DS information is inaccurately represented in the EMR leading to safety concerns and negatively impacting overall quality-of-care. Participants desired an app designed with: 1) Health Insurance Portability and Accountability Act (HIPAA)-compliance; 2) ease of use for a variety of technical efficacy levels; 3) access to reliable DS information, including a DS-drug interaction checker; 4) integration with the EMR. Conclusion: An app to simplify and improve DS entry and reconciliation was of interest to patients, as long as it maintained health autonomy and privacy and possessed key valuable features.

A systematic review of communication about Complementary and Integrative Health (CIH) in global biomedical settings

OBJECTIVES

A systematic review to analyze communication rates of complementary and integrative health (CIH) and analyze how communication terms, such as "disclosure," are measured and operationalized.

METHODS

We searched seven databases for studies published between 2010 and 2018 with quantitative measurements of patients' communication of CIH to a biomedical clinician. We analyzed communication terms used to describe patients reporting CIH usage. We also examined the conceptual and operational definitions of CIH provided and whether those terms were explicitly operationalized. We aggregated the percentage, rate, or ratio of CIH users that communicated about CIH with their clinicians by disease type and geographical region.

RESULTS

7882 studies were screened and 89 included in the review. Studies used a wide range of conceptual and operational definitions for CIH, as well as 23 different terms to report communication related to reporting CIH usage. Usage varied by disease type and geographical region.

CONCLUSIONS

Studies of CIH and CIH communication may measure different kinds of social and communicative phenomena, which makes comparison across international studies challenging.

PRACTICE IMPLICATIONS

Future studies should employ standardized, replicable measures for defining CIH and for reporting CIH communication. Clinicians can incorporate questions about prior, current, and future CIH use during the medical visit.

Self-Perceived Health and Chronic Conditions Among Users of Supplements With and Without Botanical Ingredients: Findings from the 2009-2014 National Health and Nutrition Examination Survey

The objective of this research was to investigate associations among self-reported health status, chronic conditions, and use of dietary supplements containing botanicals and describe reasons for use among U.S. adult supplement users. This was a cross-sectional analysis using data from the 2009-2014 National Health and Nutrition Examination Survey (NHANES). Supplement information was collected with a 30-day recall interview. Self-reported general health status and doctor-informed diagnoses of chronic conditions were assessed using a health status questionnaire. We used weighted multivariate logistic regressions to assess associations between supplement use and perceived health and number of chronic conditions. Participants were 16,958 non-institutionalized U.S. adults aged 20 years and older. Adults with excellent or very good self-perceived health were more likely to use botanical supplements than adults with good perceived health (adjusted odds ratio [aOR], 1.48; 95% confidence interval [CI], 1.28-1.74). Adults with three or more chronic conditions were more likely to report using botanical supplements than adults with no chronic conditions (aOR, 1.49; 95% CI, 1.13-1.69). The most frequently reported reasons for both non-botanical and botanical supplements use were "personal choice or influenced by advertisements or word of mouth," "improve health," and "specific health conditions" (93.3%, 84.2%, and 64.7%, respectively). While perceptions of health are more positive among adults using botanical supplements, chronic conditions and reasons for botanical supplements use related to personal choice, improving health, or addressing specific conditions were more likely. Differentiating botanical supplements from other complementary and integrative therapies may be useful for facilitating a deeper understanding of the reasons.

Integrative medicine smart phrase pilot study: Evaluating an EHR tool to improve providers' attitudes, knowledge and use of herbal and dietary supplements

CONTEXT

While many patients use herbal and dietary supplements (H/DS) for wellness, disease prevention and treatment, providers still cite a lack of resources and formal training as barriers to responding to patients' inquiries about H/DS. Although the federal government, academic institutions and the private sector now offer more opportunities for education and research on H/DS, greater support in real time is needed to facilitate providers during the clinical encounter.

OBJECTIVE

This small, pilot study evaluates the effects of implementation of smart phrases in the electronic health record (EHR) and an educational intervention on providers' knowledge, attitude and use of H/DS in the clinical encounter.

DESIGN, SETTING AND PARTICIPANTS

The study was conducted at The Institute for Family Health (IFH), a Federally Qualified Health Center and academic health center which operates the Department of Family Medicine and Community Health in affiliation with the Icahn School of Medicine at Mount Sinai. Baseline and post-intervention surveys were conducted to explore providers' attitudes, knowledge and use of integrative medicine (IM) smart phrases on H/DS.

MAIN OUTCOME MEASURES

Providers' awareness of smart phrases of H/DS, knowledge of the content, confidence in using smart phrases to discuss H/DS, self-reported use of smart phrases were measured.

RESULTS

A total of 32 subjects participated in the intervention and completed the baseline survey. Only half of the participants were familiar with the IM smart phrases in our system and 12.5% felt they were aware of the information covered in these smart phrases. Eighteen of 32 participants completed the post-intervention assessment. The intervention was successful in statistically increasing participants' self-reported awareness of the information covered in the IM smart phrases (p<0.01). Increased confidence in using IM smart phrases to initiate patients on a new supplement showed statistical significance (p=0.03). There were no clear patterns in reported behavior changes following the training with the exception of a significant increase in the self-reported frequency of past month use of IM smart phrases during a patient visit (p=0.01). Lastly, there were no changes in the frequency of smart phrase use in the EHR.

CONCLUSION

The implementation and adoption of evidence-based use of H/DS in the clinical encounter requires a sustained educational component to make the availability of smart phrases via technology (EHR) an effective strategy.

Prevalence and Knowledge of Potential Interactions Between Over-the-Counter Products and Apixaban

BACKGROUND

Direct-acting oral anticoagulants (DOACs), such as apixaban, are the most commonly prescribed anticoagulants, with advantages in that they do not require routine monitoring. However, less frequent contact with healthcare professionals may contribute to poor patient knowledge about potential interactions between over-the-counter (OTC) products and DOACs.

OBJECTIVE

Determine the prevalence of use of OTC products (OTC medications and dietary supplements) with potentially serious apixaban interactions and assess patient knowledge of potential interactions.

DESIGN

Cross-sectional survey.

SETTING

Academic-affiliated outpatient medical practices in northern and southern California.

PARTICIPANTS

A total of 791 English- or Spanish-speaking patients prescribed apixaban.

MEASUREMENTS

Use and knowledge of OTC medications and dietary supplements with potentially serious apixaban interactions.

RESULTS

Almost all respondents (n = 771; 97.5%) reported OTC product use. Of respondents, 33% (n = 266) took at least one OTC product with potentially serious apixaban interactions daily/most days and 53 (6.7%) took multiple products (mean = 2.6 [SD = 2.6]). Aspirin was taken daily by 116 (14.7%; of which 75 [64.7%] also consumed other potentially interacting OTC products), and some days/as needed by an additional 82 (10.4%). Ibuprofen and naproxen were taken daily/most days by 14 (1.8%) and occasionally by 225 (28.5%). Dietary supplements with potentially serious interactions were taken daily/most days by 160 (20.2%). Approximately 66% of respondents were either uncertain or incorrect about the potential for increased bleeding from combining nonsteroidal anti-inflammatory drugs and apixaban. Less knowledge about OTC products with potentially serious interactions was associated with greater OTC product use (odds ratio = 0.54; 95% confidence interval = 0.35-0.85).

CONCLUSION

Significant numbers of patients take OTC products (particularly dietary supplements) with potentially serious interactions with the DOAC apixaban and appear to lack knowledge about potentially harmful interactions. Interventions are needed to educate patients and healthcare providers about potential dangers of taking interacting OTC products in combination with apixaban, and data are needed on outcomes associated with concomitant apixaban-OTC product use.

Patient Disclosure of Complementary and Integrative Health Approaches in an Academic Health Center

Background

Effective patient–doctor communication about complementary and integrative health (CIH) is crucial to coordinate multimodal treatment for complex conditions. While rates of patient disclosure of CIH use to physicians have increased in the United States over the last 30 years, many patients still do not disclose these facts. Integrating CIH approaches within academic medical centers may enhance the communication, but this has not been explicitly studied.

Objective

To examine rates of patient disclosure of CIH to physicians and reasons for nondisclosure.

Methods

We surveyed 1177 patients at an academic center’s CIH clinic regarding their CIH use and disclosure of CIH use to their physician.

Results

Of the 1067 who responded to the disclosure questions, 80.1% had discussed their CIH use with their physician, while 19.9% did not. Of those who did not disclose, lack of physician inquiry was reported by 58% as the principal reason.

Discussion

Within an academic center, there is still a need to improve communication about CIH use. Possible strategies might include continued education of both patients and physicians about CIH and communication skills and integration of CIH disclosure into routine patient health questionnaires.

Epidemiology of dietary supplement use in Serbia: Report from Novi Sad

OBJECTIVES

The primary objectives were to assess the prevalence of dietary supplement (DS) use and to identify specific demographic and lifestyle characteristics of DS users from Novi Sad, Serbia as well as the most commonly used DS and reasons for their use.

DESIGN

Observational, cross-sectional study.

SETTING AND INTERVENTIONS

Data on demographics, lifestyle and dietary supplement use of 435 adults from Novi Sad, Serbia were collected using an online questionnaire.

RESULTS

In total, 435 subjects completed the questionnaire (62.3% women). Prevalence of dietary supplement use in the sample was 42.8%. More women used DS than men (p = 0.002). Higher use of DS was reported among individuals 65+, while the young used DS less (p = 0.001), but the highest proportions of DS users was from the 45-54 age group. DS were used more among those with lower education levels (p < 0.001) and no income (p = 0.009). The highest percentages of DS users reported daily intakes of fruits and moderate physical activity, were non-smokers and social drinkers. Main reason for DS use was maintaining general health. The most commonly used DS were minerals and/or vitamins (68.8%).

CONCLUSIONS

We report a high prevalence of dietary supplement use in Novi Sad. DS use was associated with being a female, being older and having minimal/average income, the latter being opposite of the usual findings. Our results warrant a more detailed examination of the association between income, DS use and healthcare availability in developing countries such as Serbia.

Patient's knowledge and awareness about the effect of the over-the-counter (OTC) drugs and dietary supplements on laboratory test results: a survey in 18 European countries

Background Nowadays over-the-counter (OTC) drugs and dietary supplements are widely used. Their use can have a significant impact on the validity of laboratory results. The aim of this multicenter European study was to determine the frequency of consumption of various dietary products and OTC drugs among patients and explore their level of knowledge and awareness about the potential impact of various products on laboratory test results. Methods Eighteen European countries participated in this study. The survey was carried out anonymously on a subsequent series of outpatients (n=200) in each participating country. Included were patients who were referred to the laboratory for blood sampling and who voluntarily agreed to participate in the study. The survey included questions about the frequency of consumption of various products, awareness of the importance of informing physicians and laboratory staff about it and information about influence of preanalytical factors in general on laboratory test results. Results In total, 68% of patients were regularly taking at least one OTC drug or dietary supplement. The frequency of patients consuming at least one OTC drug or dietary supplement differed between countries (p=0.001). Vitamins (38%), minerals (34%), cranberry juice (20%), acetylsalicylic acid (ASA) (17%) and omega fatty acids (17%) were the most commonly used in our study. Conclusions The use of various OTC drugs and dietary supplements is highly prevalent in Europe and patients are often not willing to disclose this information to the laboratory staff and ordering physician. The education of both patients and healthcare staff is needed.

Factors Related to Disclosure and Nondisclosure of Dietary Supplements in Primary Care, Integrative Medicine, and Naturopathic Medicine

Background:

Patients infrequently disclose use of dietary supplements to providers. Little is known about factors that motivate patients to disclose supplement use. The study aimed to identify reported factors motivating patients’ disclosure and nondisclosure of dietary supplement use and explore differences based on type of supplement and provider practice.

Methods:

Mixed methods study combining qualitative content analysis of semi-structured interviews with statistical analyses to assess differences in identified factors by provider practice type and supplement type. Seventy-eight English-speaking patients who reported taking 466 dietary supplements in the previous 30 days were recruited from primary care and Complementary and Alternative Medicine (CAM), and Integrative Medicine (IM) offices in Southern California.

Results:

We identified nine themes related to disclosure and nine related to nondisclosure of dietary supplement use. Major themes were features of the office visit, circumstances in patient health and medical care, and provider/patient characteristics. The most commonly raised theme promoting disclosure of supplement use was provider inquiry. Patients associate disclosure with having concerns about a supplement but also with annual physical exams and some routine topics of discussion, including self-care, lab results, and new medication prescriptions. Themes related to nondisclosure included lack of provider inquiry, features of the office visit, such as supplements being unrelated to the visit purpose, and patients’ convictions that supplements are safe or not important to discuss. Themes did not vary by supplement type. Primary care patients were more likely than CAM/IM patients to attribute nondisclosure to convictions that supplements were beneficial, not worth mentioning, or equivalent to food (p ≤ 0.001).

Conclusions:

When providers fail to ask directly about dietary supplement use, disclosure is often an impromptu decision that is driven by the content of provider-patient interactions. Ensuring disclosure of dietary supplement use to prevent potential drug-supplement interactions or adverse health outcomes likely requires consistent, proactive provider queries about supplement use.

Behaviors and Attitudes toward the Use of Complementary and Alternative Medicine among Korean Cancer Patients

PURPOSE

A cross-sectional survey was conducted to explore the current awareness and use of complementary and alternative medicine (CAM), as well as attitudes toward CAM, in patients with cancer and their family members in South Korea.

MATERIALS AND METHODS

Between September 21 and October 31, 2017, a 25-item questionnaire regarding CAM experiences among cancer patients and their family members was conducted in 10 oncology clinics in South Korea after institutional review board approval at each institution.

RESULTS

In total, 283/310 patients were analyzed. The median age was 60 years, and 60% were male. Most of the patients were actively receiving anticancer treatment at the time of the survey. A total of 106 patients (37%) had experienced a median of two types (interquartile range, 1 to 3) of CAM. Belief in CAM (odds ratio [OR], 3.015; 95% confidence interval [CI], 1.611 to 5.640) and duration of disease (OR, 1.012; 95% CI, 1.004 to 1.020) were independent factors for using CAM in multivariable analysis. Belief in CAM was significantly associated with current use of CAM (OR, 3.633; 95% CI, 1.567 to 8.424). Lay referral was the most common reason for deciding to use CAM, and only 25% of patients (72/283) discussed CAM with their physicians.

CONCLUSION

Patient attitudes toward and confidence in CAM modalities were strongly associated with their CAM experiences, and only a small number of patients had an open discussion about CAM with their physicians. A patient education program for CAM is needed.

Disclosure of complementary medicine use to medical providers: a systematic review and meta-analysis

Concomitant complementary medicine (CM) and conventional medicine use is frequent and carries potential risks. Yet, CM users frequently neglect to disclose CM use to medical providers. Our systematic review examines rates of and reasons for CM use disclosure to medical providers. Observational studies published 2003-2016 were searched (AMED, CINAHL, MEDLINE, PsycINFO). Eighty-six papers reporting disclosure rates and/or reasons for disclosure/non-disclosure of CM use to medical providers were reviewed. Fourteen were selected for meta-analysis of disclosure rates of biologically-based CM. Overall disclosure rates varied (7-80%). Meta-analysis revealed a 33% disclosure rate (95%CI: 24% to 43%) for biologically-based CM. Reasons for non-disclosure included lack of inquiry from medical providers, fear of provider disapproval, perception of disclosure as unimportant, belief providers lacked CM knowledge, lacking time, and belief CM was safe. Reasons for disclosure included inquiry from medical providers, belief providers would support CM use, belief disclosure was important for safety, and belief providers would give advice about CM. Disclosure appears to be influenced by the nature of patient-provider communication. However, inconsistent definitions of CM and lack of a standard measure for disclosure created substantial heterogeneity between studies. Disclosure of CM use to medical providers must be encouraged for safe, effective patient care.

Analysis of oral dietary supplement use in rural older adults

AIMS AND OBJECTIVES

To describe and explore characteristics associated with oral dietary supplement use and identify potential interactions with prescription medications in a sample of rural community-dwelling older adults.

BACKGROUND

Older adults use polypharmacy to help manage chronic diseases. Due to healthcare access disparities, rural older adults may consider dietary supplement use as an alternative approach to maintain health and manage disease. Oral dietary supplement use is expected to increase among ageing adults; placing them at risk for potential interactions and adverse events.

DESIGN

A secondary analysis was conducted on oral dietary supplement, medication and health characteristic data collected on N = 138 participants. The original study was adherent to STROBE guidelines.

RESULTS

Researchers found that 83% of the rural older adults used oral dietary supplements in addition to their prescribed medications. Participants took additional single-dose vitamins along with their multivitamin; 57% took vitamin D, 52% took calcium, 15% took vitamin C and 13% took additional potassium and vitamin E. Participants also used oral dietary supplements with medications that had a potential for interaction.

CONCLUSIONS

Compared with national samples of older adults, a high percentage of rural older adults used oral dietary supplements in addition to their prescribed medications. In the rural setting, older adults are at risk for potential drug-oral dietary supplement interactions.

RELEVANCE TO CLINICAL PRACTICE

Nurses can conduct vigilant medication reconciliation that includes documenting characteristics of oral dietary supplement use. Nurses can assist with providing appropriate dietary supplements education that promotes patient knowledge and prevent inappropriate use; particularly when caring for older adults from rural settings.

Herb-Induced Liver Injuries in Developing Nations: An Update

The last few decades have seen a rise in the use of herbal supplements, natural products, and traditional medicines. However, there are growing concerns related to the safety and toxicities of these medicines. These herbal medicines are associated with complications such as liver damage with a high incidence of mortalities and morbidities. Clinical manifestations range from asymptomatic cases with abnormal liver functions tests to sudden and severe liver failure necessitating liver transplantation. This work aimed to review the etiology, risk factors, diagnosis, clinical manifestations and selected clinical case reports of herbal hepatotoxicity in developing nations. PubMed and Google Scholar searches were undertaken to identify relevant literature. Furthermore, we scanned the reference lists of the primary and review articles to identify publications not retrieved by electronic searches. Little data exists on clinical cases of herb-induced liver injury in some developing countries such as Nigeria, as most incidences are either not reported to health care providers or reports from hospitals go unpublished. Studies in Nigeria have highlighted a possible correlation between use of herbs and liver disease. In Uganda, and association between the use of traditional herbal medicine with liver fibrosis in HIV-infected and non-HIV patients was demonstrated. Reports from China have revealed incidences of acute liver failure as a result of herbal medicine use. The actual incidence and prevalence of HILI in developing nations remain largely unknown due to both poor pharmacovigilance programs and non-application of emerging technologies. Improving education and public awareness of the potential risks of herbals and herbal products is desirable to ensure that suspected adverse effects are formally reported. There is need for stricter regulations and pre-clinical studies necessary for efficacy and safety.

Factors associated with the use of dietary supplements and over-the-counter medications in Japanese elderly patients

Background

The use of dietary supplements and over-the-counter (OTC) drugs is increasing, and there is adequate concern about potential harmful effects. However, there are limited reports on the concurrent use of nonprescription medications with prescription medications in elderly patients. Therefore, this study was conducted to describe the use of dietary supplements and OTC drugs, and to identify predictors for their use in elderly patients using medications prescribed for chronic diseases.

Methods

This was a cross-sectional study that enrolled 729 patients aged ≥65 years with chronic diseases, between January and March 2016. Data regarding socio-demographic status, medical condition, number of prescriptions, use of nonprescription medications, and psychological status were collected using a self-administered questionnaire and by review of medical records. Data regarding use of dietary supplements and OTC drugs were analyzed using descriptive statistics. Logistic regression analysis was applied to investigate factors associated with the use of dietary supplements and OTC drugs.

Results

The regular use of nonprescription drugs was reported by 32.5% of patients. Vitamins were the most commonly used dietary supplements in elderly patients. Female sex, higher educational qualifications, and good economic status were identified as predictors for the use of nonprescription medications. Concurrent use of nonprescription medications with more than 5 prescription medications was detected in 12.2% of participants. The disclosure rate of the use of nonprescription medications by patients to the physician was 30.3%.

Conclusion

The use of dietary supplements and OTC drugs was common in elderly patients with chronic diseases, and its use is associated with sex, education, and economic status. General practitioners (GPs) need to recognize the potential use of nonprescription medications, considering that polypharmacy was common and disclosure rate was low in this study.

Weight loss drugs and lifestyle modification: Perceptions among a diverse adult sample

OBJECTIVES

Explore how adults from diverse racial and socioeconomic backgrounds perceive the use of weight loss drugs (prescription, over-the counter, herbals and supplements) and lifestyle modification.

METHODS

Individual, face-to-face, semi-structured interviews were conducted with persons presenting to an academic hospital-affiliated outpatient pharmacy serving ethnic minorities and low income individuals.

RESULTS

Fifty persons were interviewed, including 21 African Americans, 11 Hispanics and 17 low-income individuals (annual income <$20,000), of whom 33 self-reported as overweight or obese. Ever-users (14/50) and nonusers (36/50) of weight loss drugs expressed a belief in the importance of diet and exercise, but were not necessarily doing so themselves. Fear of side effects and skepticism towards efficacy of drugs deterred use. Some expressed concern over herbal product safety; others perceived herbals as natural and safe. Drugs were often viewed as a short-cut and not a long-term weight management solution.

CONCLUSION

A range of concerns related to the safety and efficacy of weight loss drugs were expressed by this lower income, ethnically diverse population of underweight to obese adults.

PRACTICE IMPLICATIONS

There is need and opportunity for healthcare providers to provide weight loss advice and accurate information regarding the safety and efficacy of various types of weight loss approaches.

Provider Recommendations in the Face of Scientific Uncertainty: An Analysis of Audio-Recorded Discussions about Vitamin D

BACKGROUND

Little is known about how providers communicate recommendations when scientific uncertainty exists.

OBJECTIVES

To compare provider recommendations to those in the scientific literature, with a focus on whether uncertainty was communicated.

DESIGN

Qualitative (inductive systematic content analysis) and quantitative analysis of previously collected audio-recorded provider-patient office visits.

PARTICIPANTS

Sixty-one providers and a socio-economically diverse convenience sample of 603 of their patients from outpatient community- and academic-based primary care, integrative medicine, and complementary and alternative medicine provider offices in Southern California.

MAIN MEASURES

Comparison of provider information-giving about vitamin D to professional guidelines and scientific information for which conflicting recommendations or insufficient scientific evidence exists; certainty with which information was conveyed.

RESULTS

Ninety-two (15.3 %) of 603 visit discussions touched upon issues related to vitamin D testing, management and benefits. Vitamin D deficiency screening was discussed with 23 (25 %) patients, the definition of vitamin D deficiency with 21 (22.8 %), the optimal range for vitamin D levels with 26 (28.3 %), vitamin D supplementation dosing with 50 (54.3 %), and benefits of supplementation with 46 (50 %). For each of the professional guidelines/scientific information examined, providers conveyed information that deviated from professional guidelines and the existing scientific evidence. Of 166 statements made about vitamin D in this study, providers conveyed 160 (96.4 %) with certainty, without mention of any equivocal or contradictory evidence in the scientific literature. No uncertainty was mentioned when vitamin D dosing was discussed, even when recommended dosing was higher than guideline recommendations.

CONCLUSIONS AND RELEVANCE

Providers convey the vast majority of information and recommendations about vitamin D with certainty, even though the scientific literature contains inconsistent recommendations and declarations of inadequate evidence. Not communicating uncertainty blurs the contrast between evidence-based recommendations and those without evidence. Providers should explore best practices for involving patients in decision-making by acknowledging the uncertainty behind their recommendations.

Clinical Features and Outcomes of Complementary and Alternative Medicine Induced Acute Liver Failure and Injury

OBJECTIVES

The increasing use of complementary and alternative medicines (CAMs) has been associated with a rising incidence of CAM-induced drug-induced liver injury (DILI). The aim of this study was to examine the clinical features and outcomes among patients with acute liver failure (ALF) and acute liver injury (ALI) enrolled in the Acute Liver Failure Study Group database, comparing CAM-induced with prescription medicine (PM)-induced DILI.

METHODS

A total of 2,626 hospitalized patients with ALF/ALI of any etiology were prospectively enrolled between 1998 and 2015 from 32 academic transplant centers. Only those with CAM or PM-induced ALI/ALF were selected for analysis.

RESULTS

A total of 253 (9.6%) subjects were found to have idiosyncratic DILI, of which 41 (16.3%) were from CAM and 210 (83.7%) were due to PM. The fraction of DILI-ALF/ALI cases due to CAM increased from 1998-2007 to 2007-2015 (12.4 vs. 21.1%, P=0.047). There was no difference in the type of liver injury-hepatocellular, cholestatic, or mixed-between groups as determined by R score (P=0.26). PM-induced DILI showed higher serum alkaline phosphatase levels compared with the CAM group (median IU/L, 171 vs. 125, P=0.003). The CAM population had fewer comorbid conditions (1.0 vs. 2.0, P<0.005), higher transplantation rates (56 vs. 32%, P<0.005), and a lower ALF-specific 21-day transplant-free survival (17 vs. 34%, P=0.044).

CONCLUSIONS

CAM-induced DILI is at least as severe in presentation as that observed due to PM with higher rates of transplantation and lower transplant-free survival in those who progress to ALF. This study highlights the increasing incidence of CAM-induced liver injury and emphasizes the importance of early referral and evaluation for liver transplantation when CAM-induced liver injury is suspected.
