Factors associated with gastrostomy tube feeding in dementia: a structured literature review

Mapping and understanding the decision-making process for providing nutrition and hydration to people living with dementia: a systematic review

BACKGROUND

This systematic review aimed to explore the process of decision-making for nutrition and hydration for people living with dementia from the perspectives and experiences of all involved.

METHODS

We searched CINAHL, the Cochrane Library, EMBASE, MEDLINE and PsycINFO databases. Search terms were related to dementia, decision-making, nutrition and hydration. Qualitative, quantitative and case studies that focused on decision-making about nutrition and hydration for people living with dementia were included. The CASP and Murad tools were used to appraise the quality of included studies. Data extraction was guided by the Interprofessional Shared Decision Making (IP-SDM) model. We conducted a narrative synthesis using thematic analysis. PROSPERO registration number CRD42019131497.

RESULTS

Forty-five studies were included (20 qualitative, 15 quantitative and 10 case studies), comprising data from 17 countries and 6020 patients, family caregivers and practitioners. The studies covered a range of decisions from managing oral feeding to the use of tube feeding. We found that decisions about nutrition and hydration for people living with dementia were generally too complex to be mapped onto the precise linear steps of the existing decision-making model. Decision-making processes around feeding for people living with dementia were largely influenced by medical evidence, personal values, cultures and organizational routine. Although the process involved multiple people, family caregivers and non-physician practitioners were often excluded in making a final decision. Upon disagreement, nutrition interventions were sometimes delivered with conflicting feelings concealed by family caregivers or practitioners. Most conflicts and negative feelings were resolved by good relationship, honest communication, multidisciplinary team meetings and renegotiation.

CONCLUSIONS

The decision-making process regarding nutrition and hydration for people living with dementia does not follow a linear process. It needs an informed, value-sensitive, and collaborative process. However, it often characterized by unclear procedures and with a lack of support. Decisional support is needed and should be approached in a shared and stepwise manner.

Dementia, goals of care, and personhood: a study of surrogate decision makers' beliefs and values

Surrogate decision makers for persons with advanced dementia play a key role in making decisions about medical treatments for their loved ones. We conducted in-depth interviews of 20 surrogates to examine their goals of care preferences and beliefs about personhood. All surrogates believed the goal of comfort was important, and 30.0% believed that curing physical problems was important. Significant proportions of surrogates acknowledged dementia-related changes in patients' ability to reason, communicate, and relate to others. Qualitative findings demonstrated diverse beliefs regarding the impact of dementia on factors related to personhood, for example, dignity, respect from others, and having a life worth living. In conclusion, the surrogates we interviewed expressed diverse preferences regarding goals of care and diverse assessments about the impact of dementia on personhood.
