Use of alternative therapies in patients with dementia and mild cognitive impairment: a prospective, controlled study

General practitioners' role in safeguarding patients with dementia in their use of dietary supplements. A qualitative study

OBJECTIVE

The use of dietary supplements (DS) may cause harm through direct and indirect effects. Patients with dementia may be particularly vulnerable. This study aims to explore general practitioners' (GPs') experiences with DS use by these patients, the GPs perceived responsibilities, obstacles in taking on this responsibility, their attitudes toward DS, and suggestions for improvements to safeguard the use of DS in this patient group.

DESIGN

Qualitative individual interview study conducted February - December 2019. Data were analysed using systematic text condensation.

SETTING

Primary healthcare clinics in Norway.

SUBJECTS

Fourteen Norwegian GPs.

FINDINGS

None of the informants were dismissive of patients using DS. They were aware of the possible direct risks and had observed them in patients. Most GPs showed little awareness of potential indirect risks to patients with dementia who use DS. They acknowledged the need for caretaking of these patients. Although there were differences in practice styles, most of the GPs wished to help their patients safeguarding DS use but found it difficult due to the lack of quality assurance of product information. Furthermore, there were no effective ways for the GPs to document DS use in the patients' records. Several suggestions for improvement were given by the GPs, such as increased attention from GPs, inclusion of DS in the prescription software, and stricter regulatory systems for DS from the authorities.

CONCLUSION

The GPs had initially little awareness of this safety risk, but there were differences in practice style and attitudes towards DS. The GPs did not perceive themselves as main responsible for safe use of DS in patient with dementia. The most important reason to disclaim responsibility was lack of information about the products. One suggestion for improvement was better integration of DS in patients' medical record.

Home care service employees' contribution to patient safety in clients with dementia who use dietary supplements: a Norwegian survey

OBJECTIVE

To explore home care services (HCS) employees' professional experiences with the use of dietary supplements (DSs) in their clients with dementia. We also investigated their attributed professional responsibility concerning this use and their attitudes toward DSs in general. Differences between nurses and nurse assistants were investigated.

DESIGN

A cross-sectional survey with self-administered questionnaires.

SETTING

Home care services in six Norwegian municipalities in the period August-December 2016.

SUBJECTS

A total of 231 (64% response rate) HCS employees; 78 nurses and 153 nurse assistants (auxiliary nurses and employees without formal education).Main outcome measures: Health care employees' experiences with patient safety in clients with dementia who use DSs.

RESULTS

Fifty per cent were concerned that clients with dementia might harm their health due to DS use. Thirty-one per cent reported having intervened in order to reduce the risk. Seventy-one per cent preferred to administer DSs to clients with dementia rather than leaving this responsibility to the clients. The respondents placed the responsibility for patient safety in clients with dementia using DSs mainly with the general practitioners, while they ascribed themselves and pharmacies a medium level of responsibility. There were only minor difference between nurses and nurse assistants, and no difference in attitudes towards DSs.

CONCLUSION

Employees in HCS were concerned about the DS use in clients with dementia. Moreover, almost one-third had intervened to improve clients' patient safety. The majority indicated that HCS should administer DSs rather than the clients with dementia themselves.KEY POINTSTo our knowledge, this is the first study investigating the role of home care services with regard to patient safety in clients with dementia who use dietary supplements (DSs).•Home care service employees worried about patient safety related to DS use in clients with dementia.•Home care service employees attributed to themselves medium responsibility to ensure the safe use of DSs in these clients.•Lack of knowledge was the most important reason why home care service employees did not recommend DSs to clients.

The Utilization of Complementary and Alternative Medicine among Saudi Older Adults: A Population-Based Study

BACKGROUND

Complementary and alternative medicine (CAM) is an integral part of patients' therapeutic experience worldwide. Among Saudi older adults, less is known about CAM utilization.

OBJECTIVES

To determine the prevalence, patterns, and factors associated with CAM utilization among SOA.

METHODS

In the Saudi National Survey for Elderly Health (SNSEH), subjects were asked about CAM use during the last twelve months before the interview. CAM use was defined as any use of herbal products, acupuncture, bloodletting, cauterization, medical massage, bones manual manipulation, honey, or religious rituals. Demographic characteristics included gender, age, marital status, region, educational level, and residence area. In addition, multiple comorbidities were included as possible factors that may be associated with CAM use. Multivariable logistic regression was used to explore factors associated with CAM utilization. All statistical analyses were done using STATA v.14.

RESULTS

Out of 2946 respondents, 50.4% were males, the mean age was 70.3 ± 8.3 years, and 70% were illiterate. CAM use was prevalent (62.5%). The most common CAM types were herbal products (25.4%), acupuncture (21.2%), bloodletting (12%), honey (9.5%), cauterization (7.4%), medical massage and bones manual manipulation (4%), and traditional bone setting (2.1%). In the multivariable regression, age, gender, and marital status did not have an impact on the odds of using CAM. Subjects from rural areas were 2.92 times more likely to use CAM compared with subjects in urban areas (OR = 2.92; 95%CI: 2.28-3.75). Subjects with metabolic disorders (OR = 0.50; 95% CI: 0.42-0.60) or kidney disease were less likely to use CAM (OR = 0.30; 95%CI: 0.14-0.64). About pain, CAM is used more in neck pain (OR = 1.69; 95%CI: 1.30-2.21) and also used in back pain (OR =  1.22; 95%CI: 1.03-1.46).

CONCLUSIONS

CAM use was very prevalent among SOA. Clinicians and pharmacists must ask about CAM use among older adults as many of CAM may interact with patients medications.

Pharmacy employees' involvement in safeguarding persons with dementia who use dietary supplements: Results from a survey of Norwegian pharmacies

Background

Community-dwelling persons with dementia commonly use dietary supplements (DS), often without receiving help with the administration. Patient safety is a concern, as DS-drug interactions and adverse events are potential complications. Since many persons with dementia buy their DS in pharmacies, we investigated Norwegian pharmacy employees’ attitudes and professional practice behaviors related to DS.

Methods

We conducted a survey in eight Norwegian municipalities of pharmacy employees involved in the sale of DS. The questionnaire covered demographics and investigated attitudes toward DS, professional practice behaviors related to the sale of DS, experiences with customers with dementia, and perceived and attributed responsibilities with regard to patient safety.

Results

One hundred and five employees responded (response rate: 52%). Most employees regarded general practitioners (GPs) as primarily responsible for safeguarding the use of DS by persons with dementia and rated themselves less responsible. Thirty-seven percent of the employees reported personal use of DS (past or current use). Nine percent considered some of the DS to have symptomatic or prophylactic effects against dementia. Forty-eight percent confirmed that they informed customers about potential adverse events; 42% indicated that they did this sometimes. Sixteen percent checked regularly for DS-drug interactions, and two-thirds checked depending on the customers’ health, the type of drug or the type of DS. One-quarter regularly asked about the co-use of prescription drugs (PD) when selling DS, while only 2% asked about the co-use of DS when dispensing PD. Only 25% reported access to independent scientific information on all or most DS sold in their pharmacy. Eight percent had experienced unsafe use of DS by persons with dementia. Six percent had been taught about counselling persons with dementia. Education level influenced professional practice behavior to some extent.

Conclusion

Pharmacy employees do not see themselves as primarily responsible for the safe use of DS by persons with dementia. Moreover, they have limited experience with the unsafe use of DS by these persons. There is potential for improvement regarding tools and educational interventions for pharmacy employees to provide sufficient help to persons with dementia who use DS.

Direct and indirect risk associated with the use of dietary supplements among persons with dementia in a Norwegian memory clinic

BACKGROUND

The use of dietary supplements (DS) is common among persons with dementia. Direct risks associated with DS use include adverse events and DS-drug interactions. A direct risk is a risk caused by the treatment itself. Indirect risks are related to the treatment setting, such as the conditions of use, and not to the treatment itself. Because dementia symptoms may reduce a person's ability to cope with the administration of DS, the use of DS may pose a threat to safety as an indirect risk. The aim of this study was to describe the extent of DS use among persons with dementia in ambulatory care and to identify some relevant direct and indirect risks related to DS use.

METHODS

We conducted a survey among 151 persons with dementia attending an outpatient memory clinic in Northern Norway. Study measurements included: the participants' characteristics, cognitive functioning, functioning in the activities of daily living (ADL), and the use of DS and prescription drugs (PD). We assessed direct risks by evaluating potential DS-drug interactions and indirect risks by evaluating the conditions under which it was used.

RESULTS

Forty-six percent (n = 70) of the persons with dementia used DS. Ninety-seven percent (n = 147) used PD. We found potentially clinically relevant DS-drug interactions representing a direct risk in eight persons with dementia (11% of users). While only 36% (n = 26) of the participants received assistance with the administration of DS, 73% (n = 106) received assistance with the administration of PD. Persons with dementia living alone were at risk of not receiving assistance, as home care service seldom was involved in DS administration. Data indicated that assistance with DS administration was not provided for all persons with dementia in need, representing an indirect risk to these persons. Only one-third of the persons with dementia and half of the caregivers were aware of the general risks of adverse events and interactions associated with the use of DS.

CONCLUSIONS

Persons with dementia use DS frequently, yet DS use may be associated with direct and indirect risks to patient safety as potentially clinically relevant interactions were discovered and DS intake often was unsupervised.

Utilization of vitamins, herbals, and over-the-counter products to delay progression of dementia

Many consumers use alternative preparations such as herbals, vitamins, and over-the-counter products in an attempt to prevent or improve the outcome of dementia. Despite use by almost half of all patients, evidence supporting their utilization is either conflicting or lacking. Omega-3 fatty acids, vitamin B6, vitamin B12, vitamin C, and beta-carotene currently do not have clinical trials showing evidence impacting the progression or treatment of symptoms associated with dementia. In addition, conflicting data exist pertaining to the beneficial utilization of ginkgo biloba and nonsteroidal anti-inflammatory drugs associated with dementia treatment. While a link to the utility of folate associated with areas of improved cognitive functioning has been suggested, further studies are needed. Vitamin E may have some benefit in patients with Alzheimer's disease, however, may also have risks in patients with comorbid diseases such as cardiovascular disease or diabetes mellitus. With limited options still existing today in the treatment of dementia, the importance of further studies to quantify alternative therapies remains an important topic.

Use of dietary supplements for cognitive health: results of a national survey of adults in the United States

We studied use of vitamins, minerals, herbs, and other dietary supplements for cognitive health. We refer to these products as supplements. Data were from the 2007 National Health Interview Survey, which asked about complementary and alternative medicine (n = 22 783). Chi-square and multivariate logistic analyses were weighted for national representativeness, accounting for the survey design. Among supplement users, about 8.8% of those without cognitive problems used them for cognitive health; 15.7% of those with cognitive problems did so. Fish oil, Ginkgo biloba, and vitamins were commonly used for cognitive health. Among supplement users, 38% did not tell health care providers. In adjusted results, adults reporting cognitive problems were more likely than others to use supplements for cognitive health (odds ratio 1.77, confidence interval 1.39-2.25). Adults are more likely to use supplements to treat or cure cognitive problems than to prevent them. Many do not discuss this use with health care providers.
