Nutritional care of older patients: experiences of general practitioners and practice nurses

A review of primary healthcare practitioners' views about nutrition: implications for medical education

OBJECTIVES

This study aimed to review literature that reports on the perspectives and opinions of Australian and New Zealand primary healthcare practitioners on their role in nutrition counselling of their patients.

METHODS

A systematic search of relevant articles reporting on attitudes towards nutrition counselling by Australian and New Zealand doctors/physicians, nurses including midwives, pharmacists and dentists was conducted. The search included literature from the past ten years until March 2021 and identified 21 relevant papers, with most of the studies including medical practitioners and nurses.

RESULTS

Three main themes were identified from qualitative and quantitative data, which included education and training, practitioner experiences and challenges. Consistent with previous literature, health care practitioners acknowledged their important role in the provision of dietary advice to patients. Challenges that influenced the provision of this advice included insufficient education and training, time constraints and limited knowledge and confidence. Time constraints during normal consultations led to a low priority of nutrition counselling. An absence of assessment opportunities to demonstrate nutrition competence and limited coverage of specific nutrition-related advice during training were also reported.

CONCLUSIONS

Primary healthcare practitioners acknowledge the importance of playing a role in the provision of nutrition advice but require education and access to evidence-based information that can be utilised effectively within the time constraints of standard consultations. Medical education curricula can be improved to provide more emphasis on nutrition education, including relevant assessment opportunities.

Community-Living Older Adults' Perceptions of Body Weight, Signs of Malnutrition and Sources of Information: a Descriptive Analysis of Survey Data

BACKGROUND

Community-living older adults may be susceptible to malnutrition (undernutrition) due to both physiological and non-physiological causes. The condition develops over time and the early signs and symptoms may not be obvious. Therefore awareness and early identification of nutrition risk factors may prevent, or at least slow, the progression of malnutrition.

OBJECTIVE

To describe community-living older adults' understanding of the signs of malnutrition, where they would seek malnutrition information and their self-perception of body weight.

DESIGN

Older adults (aged ≥ 65 years) living in the community setting completed an online or paper based questionnaire between May and August 2016. The questionnaire contained a mix of closed and open questions which related to weight perception, weight changes, perceived signs of malnutrition and sources of malnutrition information. Body mass index (BMI) from self-reported data was classified using BMI reference ranges for older adults and compared to self-perceived weight status. Textual data regarding the signs of malnutrition were analysed and reviewed by two authors using content analysis. Descriptive statistics were used to describe participant characteristics.

RESULTS

A total of 344 responses were received, the majority (90%) completed online. Mean participant age was 73 years and 57% of participants were female. Most (92%) reported their health to be good/very good. Body weight was perceived to be just right or more than it should be by 87% of underweight women and 97% of underweight men. Although 71% of the participants indicated their body weight had remained stable in the past six months, 37% reported they had been trying to change their weight. Signs of malnutrition resulted in four key categories of (i) psychological, (ii) physical appearance, (ii) bodily function and (iv) weight change. Very few reported the need to locate malnutrition information and indicated the top three sources for information would be (i) general practitioner, (ii) dietitian or (iii) internet.

CONCLUSION

This paper has presented useful data about malnutrition from the perspective of the community-living older adult. We found there may be uncertainty about the best weight, for older age. As many indicated they had been trying to change their weight, awareness needs to be raised regarding the impact of weight changes on health outcomes in this population. In this study, the internet appeared to be a key provider of nutrition information. Healthcare professionals need to consider how this can be used in an informative manner among community living older adults as a tool for raising awareness about nutrition risk and malnutrition.
