A systematic scoping review of interventions to improve appropriate prescribing of oral nutritional supplements in primary care

Pharmacists' Perceptions on Nutritional Counseling of Oral Nutritional Supplements in the Community Pharmacy: An Exploratory Qualitative Study

Malnutrition has important health impacts, especially in the elderly. Oral nutritional supplements (ONS) are effective strategies to help balance the nutritional needs of malnourished persons. Multiple ONS are available at community pharmacies, enabling pharmacists to have the possibility to implement strategies for prevention and monitoring of malnourished patients. The aim of this study was to characterize the experience of community pharmacists with the counseling and follow-up of users of ONS. A sample of 19 pharmacists from 19 different community pharmacies were interviewed. Apart from dispensing ONS to support patients that are preparing for diagnostic tests, the most frequently mentioned clinical condition for ONS counseling was malnutrition and dysphagia. When pharmacists consider dispensing ONS, three themes emerge: patient care, related to counselling tailored ONS to each patient's needs; interprofessional collaboration, with a special focus in the collaboration with registered dietitians; and training and education on ONS, looking to improve their knowledge and skills in ONS counselling and follow-up. Future studies exploring new forms of interaction between pharmacists and dietitians in this context should be developed, aiming to determine the workflow of an interdisciplinary service addressing the needs of community dwelling malnourished patients.

Impact of malnutrition management e-learning module on GPs' knowledge: a pilot study

BACKGROUND

Malnutrition is underdiagnosed in primary care. GPs are key healthcare contacts for older adults at risk of protein-energy malnutrition; however, lack of knowledge and confidence in its diagnosis and treatment is often reported.

AIM

To evaluate the impact of a bespoke online education module on GP malnutrition knowledge and management.

DESIGN & SETTING

A prospective pre-post pilot study with 23 GPs and eight GP trainees in the Republic of Ireland.

METHOD

The module included units on the following: 'malnutrition definition, prevalence, and latest evidence'; 'identifying malnutrition in clinical practice'; 'food-first advice'; 'reviewing malnutrition'; and 'oral nutritional supplements'. Participant knowledge was measured using a multiple choice questionnaire (MCQ) before and after the module (n = 31), and 6 weeks following completion (n = 11). Case studies assessing identification and management of malnutrition were evaluated by a clinical specialist dietitian with expertise in managing malnutrition. Changes in assessment performance were calculated using paired t-tests. Acceptability was evaluated using a questionnaire.

RESULTS

Post-training, 97% of GPs increased MCQ scores from baseline (+25%, P<0.001), with the greatest improvement in 'identifying malnutrition in clinical practice' (mean increase 47%, P<0.001). Eleven GPs completed the 6-week MCQ with scores remaining significantly higher than baseline (mean increase 15%, P = 0.005); 'identifying malnutrition in clinical practice' remained the most highly scored (mean increase 40%, P<0.001). Seventeen GPs completed the case studies; 76% at baseline and 88% post-module correctly calculated malnutrition risk scores. Appropriate malnutrition management improved for 47% of GPs after module completion.

CONCLUSION

This e-learning module improved malnutrition knowledge, with good short-term retention in a small cohort. Development of online evidence-based nutrition education may improve GP nutrition care.

'Between foods and medicines': A qualitative interview study of patient experiences of the meaning and usage of oral nutritional supplements

The aim of this study was to deepen the understanding of what oral nutritional supplements mean to patients and how this meaning connects to supplement usage, by exploring patient experiences of such supplements. Qualitative interviews were conducted in June 2019-March 2020 with ten patients with malnutrition or at nutritional risk, prescribed oral nutritional supplements by dietitians. Data were thematically analysed using systematic text condensation. Two final categories were identified: 'Oral nutritional supplements are a one-dimensional remedy' and 'Everyday oral nutritional supplement usage is regulated autonomously'. The patients described the meaning of oral nutritional supplements as nutrition. While the supplements could compensate for nutrients not eaten or be part of a helpful compensation strategy, they could not lessen the burden of altered eating. Supplement usage was described as dependent on the acceptance of taste and the priority given to nutrition in everyday life. Usage was greater when nutrients were perceived as needed, such as when striving for higher bodyweight or disease recovery. Usage was lower when a patient's own goals were not increased nutrient intake or bodyweight or when other activities were perceived as more important. Patient experiences indicated that oral nutritional supplements could serve as a remedy for malnutrition, but not for a situation of altered eating. Supplement usage was described as being regulated autonomously based on patient views on the importance of nutrition. Those views were diverse, highlighting the importance of supplement prescribers discussing treatment goals with each patient. A deeper understanding of the meaning of oral nutritional supplements and reasons for their usage from a patient perspective is crucial in order for healthcare to provide appropriate, effective nutrition therapy for malnutrition.

Reflections on recruiting healthcare professionals as research participants: Learning from the ONSPres Study

The involvement of healthcare professionals (HCPs) as research participants is essential to generate high quality evidence for enhancing health services and practice.  Research teams face many challenges in recruiting HCPs for research, and barriers and enablers for interdisciplinary research are not well described in the literature.  The Oral Nutritional Supplement Prescribing Malnutrition Research Study (ONSPres Study) examined malnutrition identification, management, and appropriate oral nutritional supplement prescribing in primary care in Ireland.  The ONSPres Study offers a unique view of recruiting HCPs for research because a range of disciplines were sought for participation in a mixed methods study.  The purpose of this open letter is to describe the experiences of recruitment and participation.  Sixteen general practitioners (GPs) were recruited to participate in one-to-one interviews, eighty health and social care professionals working in community care (including nurses, pharmacists, dietitians, physiotherapists, speech and language therapists, and occupational therapists) were recruited to take part in 12 focus groups, and 31 GPs and trainee GPs were recruited to participate in an education programme developed by the study team.   Strategies required to gain access and reach HCPs differed between disciplines.   Professional networks enhanced access to HCPs working in practice and recruitment was slower and more tailored when those networks were less available to the team.  An interest in malnutrition, to assist in research, to advance patient care, and the opportunity for learning were incentives for the participating HCPs.  Limitations in the diversity of the sample arose, with a bias towards female participants and GPs motivated by an interest in the topic.  It is recommended that study teams collaborate early with relevant HCP disciplines so they can contribute to recruitment planning at project concept and design stages.  To enhance and incentivise HCP participation in research, dedicated time and acknowledgement of participation as continuous professional development is proposed.

Advances in knowledge of screening practices and their use in clinical practice to prevent malnutrition

Malnutrition is common among older adults and is associated with a progressive decline in overall health and increased mortality. With a rapidly ageing population, the detection, prevention and management of malnutrition require urgent attention within health service planning and delivery. Routine screening for malnutrition among older adults in community settings, which addresses aetiological as well as phenotypic factors, is considered an important step for prevention and early intervention. The aim of this review is to summarise current malnutrition screening literature and highlight research that seeks to understand and address community-based approaches to malnutrition screening and management. Key healthcare professionals (HCPs) that encounter community-dwelling older adults include general practitioners (GPs), community-based nurses, community pharmacists and a range of other health and social care professionals including dietitians, physiotherapists, speech and language therapists, and occupational therapists. The key barriers to implementing screening in primary care include lack of knowledge about malnutrition among non-dietetic HCPs, lack of resources allocated to managing malnutrition, lack of access to dietetic services, and poor GP knowledge about oral nutritional supplement prescribing. In addition, older adults have poor insight into the clinical condition and the associated negative health implications. Investment in education among HCPs and public awareness is required, as well as accompanying resources to successfully implement malnutrition screening programmes for community-dwelling older adults.

The experiences of dietitian's working in care homes in England: a qualitative study

BACKGROUND

The provision of appropriate nutritional care in care homes is a priority for health services in England. There is limited evidence demonstrating the role of dietitians within older people care homes. This study explores the experiences of dietitians working with care homes for older people in England.

METHODS

A qualitative study using semi-structured face-to-face or telephone interviews was conducted. Criterion and snowball purposive sampling recruited six dietitian participants. Interviews were audio recorded and transcribed verbatim. A reflexive diary was completed, and data analyses followed interpretative phenomenological analyses. Constant comparison, code-recode audits, independent coding by a supervisor, supervisory support and peer review were used to promote rigour.

RESULTS

Two key themes and three subthemes were identified: Theme 1 is collaboration with multidisciplinary team (MDT) professionals and its two subthemes are as follows: using support strategies (pathway/standards implementation, training/education and resident dietetic assessment) and delivering value (by benefitting more residents, demonstrating unique dietetic skills, nutritional prescription savings and meeting other professional's knowledge gap). Theme 2 is communication with MDT professionals and its subtheme is the understanding of the dietitian's role and of nutritional care.

CONCLUSION

Dietitians believe that they play a key role in supporting care homes with nutritional care, identifying themselves as experts and leaders, working with MDT professionals. The findings highlight the importance of a consistent approach to managing nutrition and the need for dietitians to share outcome data to improve the limited evidence-base. There is a need to agree a defined dietetic service provision to care homes in England.

Implications of inappropriate prescription of oral nutritional supplements on the quality of life of cancer outpatients: a cross-sectional comparative study

Background and aims

Oral nutritional supplements (ONS) are considered a cornerstone in the treatment plan of malnutrition in cancer patients. However, the prevalence of inappropriate prescription of ONS is high. In this study, we aim to investigate the effect of inappropriate oral nutritional supplementation (consisting of prescription of ONS without evident clinical indication, or the absence of ONS when at risk of malnutrition) on the quality of life of cancer outpatients.

Methods

A cross-sectional comparative study was conducted in 104 cancer outpatients, receiving ONS without prior malnutrition risk screening (n = 51), and patients not receiving ONS (n = 53). Nutritional risk screening was performed using the abridged patient-generated subjective global assessment (ab-PG-SGA). The quality of life was assessed using EORTC QLQ-C30 version 3.0 questionnaire. Multivariate analysis was conducted to determine the predictors of quality-of-life scales. Age (years), malnutrition (ab-PG-SGA scores), BMI (kg/m²), TSF (mm), MUAC (cm), ONS (yes, no) were entered into the linear regression analysis as predictors (backward stepwise linear regression analysis).

Results

The prevalence of malnutrition risk (ab-PG-SGA ≥ 6) was 74%. The median score of the ab-PG-SGA for ONS receiving group was significantly higher (p = 0.045). Furthermore, univariate analysis showed that the scores of the global health status (QoL) and the role functioning (RF) scales were significantly lower for the ONS receiving group (p = 0.020 and p = 0.016, respectively). Multivariately, malnutrition, inappropriate ONS prescription, and triceps skin fold were found to be predictors of the RF scale, while malnutrition was the only predictor for the QoL.

Conclusion

The inappropriate ONS prescription does not improve nutritional status or quality of life of cancer outpatients.

Disparities in Oral Nutritional Supplement Usage and Dispensing Patterns across Primary Care in Ireland: ONSPres Project

When treating malnutrition, oral nutritional supplements (ONSs) are advised when optimising the diet is insufficient; however, ONS usage and user characteristics have not been previously analysed. A retrospective secondary analysis was performed on dispensed pharmacy claim data for 14,282 anonymised adult patients in primary care in Ireland in 2018. Patient sex, age, residential status, ONS volume (units) and ONS cost (EUR) were analysed. The categories of ‘Moderate’ (<75th centile), ‘High’ (75th–89th centile) and ‘Very High’ ONS users (≥90th centile) were created. The analyses among groups utilised t-tests, Mann–Whitney U tests and chi-squared tests. This cohort was 58.2% female, median age was 76 years, with 18.7% in residential care. The most frequently dispensed ONS type was very-high-energy sip feeds (45% of cohort). Younger males were dispensed more ONSs than females (<65 years: median units, 136 vs. 90; p < 0.01). Patients living independently were dispensed half the volume of those in residential care (112 vs. 240 units; p < 0.01). ‘Moderate’ ONS users were dispensed a yearly median of 84 ONS units (median cost, EUR 153), ‘High’ users were dispensed 420 units (EUR 806) and ‘Very High’ users 892 yearly units (EUR 2402; p < 0.01). Further analyses should focus on elucidating the reasons for high ONS usage in residential care patients and younger males.

'It takes a village': a qualitative study on malnutrition and oral nutritional supplements with older adults in Ireland

BACKGROUND

Malnutrition affects approximately 20% of older adult populations in Europe, yet their views on the condition are rarely explored. This qualitative study aimed to explore the experiences of older adults living with malnutrition and prescribed oral nutritional supplements in the community setting.

METHODS

Semi-structured individual interviews were used to collect data from 13 community-dwelling individuals aged ≥60 years with a current or previous prescription for oral nutritional supplements. Self-perceived health status was measured using the EuroQol EQ-5D-5L, a short questionnaire and visual analogue scale. Interviews were audio-recorded and transcribed verbatim. Interview data were organized using NVivo 12 and analyzed using inductive thematic analysis.

RESULTS

Median age was 80.0 (interquartile range 19.5) years, seven were male and six were female. Median health score was 60.0 (interquartile range 35.0) out of 100. Almost one-third reported severe or extreme problems with usual activities, and pain or discomfort. One main theme was identified from the interviews: 'It takes a village', with four subthemes (i) 'I get by with a little help from my friends', (ii) 'The obvious diagnosis', (iii) 'The missing T in MDT' and (iv) 'Confusion'. Participants with malnutrition reported relying on friends, family and carers with poor multidisciplinary team communication and lack of dietetic support.

CONCLUSIONS

Participants in this study experienced poor management of malnutrition with missing links between the hospital and community healthcare settings, and lack of dietetic services. Patient views should be used to inform public health guidelines and guide future interventions in the community to improve the health status of older adults with malnutrition.

Healthcare professionals' perceptions of malnutrition management and oral nutritional supplement prescribing in the community: A qualitative study

BACKGROUND & AIM

Protein-energy malnutrition is under-recognised in the community despite being common in older adults due to physiological and social changes which are often compounded by chronic disease. This qualitative study aimed to explore the opinions of healthcare professionals (HCPs) working in the primary care and community settings about the management of malnutrition and the prescription of oral nutritional supplements (ONS), often included in the treatment of malnutrition.

METHODS

Twelve healthcare professional (HCP) focus groups with 75 participants were conducted: community dietitians (n = 17), registered dietitians working in industry (n = 5), community and residential care nurses (n = 22), physiotherapists (n = 12), pharmacists (n = 9), occupational therapists (n = 6) and speech and language therapists (n = 4). Focus group discussions were audio-recorded and transcribed verbatim. The data were coded and analysed using thematic analysis and key themes with illustrative quotes extracted are presented.

RESULTS

Similar views on malnutrition management existed across professions. 'Gaps in Primary Care Management' was the first key theme wherein HCPs identified limitations in malnutrition management in the community. Barriers included limited or no dietetic services available in primary care and poor communication between general practitioners and wider primary care team members which resulted in inappropriate or delayed treatment. The second key theme, 'Challenges with ONS use in the Community', encapsulated several issues HCPs experienced with ONS usage including inappropriate prescribing and lack of monitoring of treatment goals. Conflicts of interest regarding dietitians working in industry assessing and treating older adults in residential care settings was highlighted by participants.

CONCLUSIONS

This study highlights that more emphasis is needed to identify patients when they are at risk of malnutrition to avoid advanced or severe malnutrition presentations currently seen. Community dietitians for older people are required to address many of the issues raised including the need for awareness, education and training, resources, and malnutrition care pathway structures.

Characteristics and determinants of high volume dispensing in long-term oral nutritional supplement users in primary care: a secondary analysis

Background

Oral nutritional supplements (ONS) are recommended for patients who are malnourished or at risk of malnutrition. Appropriate ONS prescribing requires regular monitoring to assess its continued requirement. Previous research identified long-term ONS prescriptions (>6 months) without review, with 70% of these influenced by social factors.

Aim

To investigate the characteristics of long-term ONS users in Ireland and the determinants of larger volumes of ONS dispensing.

Design & setting

Secondary analysis of anonymous dispensed pharmacy claims data of patients dispensed standard ONS for 12 consecutive months in 2018 (n = 912).

Method

Factors showing significant (P<0.05) univariate associations with above the median consumption of ONS units were entered into a multivariable model.

Results

Median age was 76 (range 18 to 101) years, with 66.9% of the sample being ≥65 years. Almost 70% of the samples were on polypharmacy (45.6%; ≥5 medications) or excessive polypharmacy (21.5%; ≥10 medications). Younger age and being on polypharmacy for drugs having an effect on the central nervous system (CNS) were significantly associated with being dispensed more ONS units in univariate and multivariate analysis. Those patients in the age range 18 to 44 were 2.5 fold more likely to be prescribed more ONS units (odds ratio [OR] 2.5; 95% confidence interval [CI] 1.5 to 4.3; P<0.001). Patients using CNS drugs or on CNS polypharmacy were more likely to be prescribed more ONS units (ORs 1.2 and 2.4; 95% CI 0.9 to 1.4 and 1.3 to 4.4 respectively; P = 0.029).

Conclusion

Older age and polypharmacy characterise long-term ONS users in this study. Younger age and CNS medication polypharmacy are predictors of more ONS units prescribed over a year.

A qualitative exploration of dietitians' experiences of prescribing oral nutritional supplements to patients with malnutrition: A focus on shared tailoring and behaviour change support

BACKGROUND

Oral nutritional supplements (ONS) are commonly prescribed to patients with malnutrition. Dietitians have been suggested as preferred prescribers but generally lack ONS prescribing rights. How dietitians with prescribing rights experience their professional practice of prescribing ONS remains understudied. Thus, by exploring dietitians' experiences of prescribing ONS, the present study aimed to obtain a deeper understanding of specific aspects that are of importance for dietitians when providing a nutrition therapy including ONS.

METHODS

Qualitative individual interviews were conducted with 13 dietitians prescribing ONS to free-living adult outpatients with malnutrition or at nutritional risk in the hospital or primary care setting. Systematic text condensation was used for data analysis.

RESULTS

Two main categories signifying important aspects were identified and labelled: 'Shared tailoring of the ONS prescription' and 'Supporting and facilitating ONS use'. First, the dietitians described tailoring the ONS prescription together with the patient, having their acceptance as a prerequisite, and being flexible regarding products and amounts prescribed. Second, they described performing different communication strategies and organising of practical issues (e.g., ONS delivery and support from others) to support and facilitate patients' ONS usage.

CONCLUSIONS

The present study identifies patient involvement and the role of dietitians as behaviour change facilitators as two important aspects when dietitians prescribe ONS. These findings allow for dietitians' ideals and strategies on how to prescribe ONS to be made more visible, which can inform both clinical practice and clinical trials for future improvements in nutrition therapy to address malnutrition.
