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.

Currently, little is known about general practitioners (GPs) caretaking of patients with dementia who use dietary supplements (DS). Our study showed that:The GPs in this study showed little awareness of the potential safety risk that DS use may represent for patients with dementia.Several obstacles in the treatment setting and in the regulation of DS make it difficult for the GPs to assume full responsibility for patients with dementia who use DS.Lack of evidence about DS safety and effect adds to professional uncertainty and may cause frustration or reluctance to address the issue.

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.

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.
