A Systematic Review of Nurse-led Dietary Interventions for Cancer Patients and Survivors

The effect of consultations performed by specialised nurses or advanced nurse practitioners on patient and organisational outcomes in patients with complex health conditions: An umbrella review

BACKGROUND

Policymakers and researchers often suggest that nurses may play a crucial role in addressing the evolving needs of patients with complex conditions, by taking on advanced roles and providing nursing consultations. Nursing consultations vary widely across settings and countries, and their activities range from complementing to substituting traditional physician-led consultations or usual care.

OBJECTIVE

This study was aimed at describing the effects of nursing consultations with patients with complex conditions in any setting on patient outcomes (quality of life, physical status, psychosocial health, health behaviour, medication adherence, mortality, anthropometric and physiological outcomes, and patient satisfaction) and organisational outcomes (health resource use and costs).

DESIGN

Umbrella review.

METHODS

We followed the Joanna Briggs Institute method for umbrella reviews. We searched PubMed, Embase, Cochrane Database of Systematic Reviews and CINAHL to identify relevant articles published in English, Dutch, French, Spanish or German between January 2013 and February 2023. We included systematic literature reviews, with or without meta-analyses, that included randomised controlled trials conducted in high-income countries. Reviews were eligible if they pertained to consultations led by specialised nurses or advanced nurse practitioners. Article selection, data extraction and quality appraisal were performed independently by at least two reviewers.

RESULTS

We included 50 systematic reviews based on 473 unique trials. For all patient outcomes, nursing consultations achieved effects at least equivalent to those of physician-led consultations or usual care (i.e., non-inferiority). For quality of life, health behaviour, medication adherence, mortality and patient satisfaction, more than half the meta-analyses found statistically significant effects in favour of nursing consultations (i.e., superiority). Cost results must be interpreted with caution, because very few and heterogeneous cost-related data were extracted, and the methodological quality of the cost analyses was questionable. Narrative syntheses confirmed the overall conclusions of the meta-analyses.

CONCLUSIONS

The effects of nursing consultations on patients with complex health conditions across healthcare settings appear to be at least similar to physician-led consultations or usual care. Nursing consultations appear to be more effective than physician-led consultations or usual care in terms of quality of life, health behaviour, mortality, patient satisfaction and medication adherence. Further analysis of the primary data is necessary to determine the patient populations and settings in which nursing consultations are most effective. Moderate study quality, diversity amongst and within systematic reviews, and quality of reporting hamper the strength of the findings.

Non-pharmacological interventions for chemotherapy-induced diarrhoea and constipation management: A scoping review

PURPOSE

Chemotherapy-induced diarrhoea (CID) and constipation (CIC) are among the most common and severe gastrointestinal symptoms related to chemotherapy. This review aimed to identify and describe the evidence for non-pharmacological interventions for the management of CID and CIC.

METHODS

The scoping review was based on the Joanna Briggs Institute methodology and reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist. Evidence from five databases were included: CINAHL, MEDLINE, Embase, PubMed, and APA PsycInfo. Data were systematically identified, screened, extracted and synthesised narratively to describe the evidence for non-pharmacological interventions and their effects on CID and CIC.

RESULTS

We included 33 studies, of which 18 investigated non-pharmacological interventions for CID management, six for CIC management, and nine for both CID and CIC management. Interventions were categorized into five groups, including (1) digital health interventions, (2) physical therapies, (3) diet and nutrition therapies, (4) education, and (5) multimodal. Diet and nutrition therapies were the most common to report potential effectiveness for CID and CIC outcomes. Most of the interventions were implemented in hospitals under the supervision of healthcare professionals and were investigated in randomised control trials.

CONCLUSIONS

The characteristics of non-pharmacological interventions were diverse, and the outcomes were inconsistent among the same type of interventions. Diet and nutritional interventions show promise but further research is needed to better understand their role and to contribute to the evidence base. Nurses are well placed to assess and monitor for CIC and CID, and also deliver effective non-pharmacological interventions.

A Systematic Review of Dietary Interventions for Cancer Survivors and Their Families or Caregivers

Family or caregiver engagement has the potential to support healthy dietary changes among cancer survivors. However, little is known about these family- or caregiver-involved dietary interventions and their effects. This systematic review aimed to identify the behavior change techniques (BCTs) used in dietary interventions for cancer survivors and their families or caregivers and to synthesize intervention effects on dietary and health outcomes. Following the PRISMA guidelines, we conducted systematic searches in three databases and identified 12 trials (16 peer-reviewed manuscripts) for inclusion in this review. Data were extracted from these manuscripts and the BCT taxonomy was used to identify the BCTs. A total of 38 BCTs were identified from 12 trials, 13 of which were used in at least half of the 12 trials. Ten studies reported significant intervention effects on health outcomes (e.g., adiposity) and six suggested significant improvements in dietary behaviors (e.g., fruit and vegetable intake). Overall, this review found that family- or caregiver-involved interventions for cancer survivors significantly improved dietary and health outcomes. Future research should identify BCTs particularly for dietary changes and develop effective dyadic strategies to facilitate diet-related interactions between survivors and their families or caregivers to enhance their engagement in healthy diets.

The effect of nurse-led empowering education on nutrition impact side effects in patients with colorectal cancer undergoing chemotherapy: A randomised trial

OBJECTIVE

This study assessed the effect of empowering education on patient-reported outcomes and morbidity.

METHODS

A randomised controlled trial was conducted on adults with colorectal cancer (43 + 40). The intervention consisted of one-hour empowering patient education on nutrition impact side effects. The effect was compared with standard care. The difference between the groups was analysed pre and post intervention.

RESULTS

The change in malnutrition-related knowledge level was higher in the intervention group compared to control group (median 0.0, IQR 1.00 vs median 0.0, IQR 0.0, p = 0.028). Additional contacts with outpatient clinic were fewer in intervention group (median 0.00, IQR 0.00) compared to control group (median 1.00, IQR 2.00, p < 0.001). We did not find a statistically significant difference in the change in activation level, risk of malnutrition and quality of life between the groups.

CONCLUSION

Empowering education may affect positively on patients' knowledge level related to malnutrition and reduce the number of additional contacts with health care thus reduce health care costs.

PRACTICE IMPLICATIONS

Empowering education may be used in patients with colorectal cancer to improve knowledge and reduce additional contacts with health care. Further research is needed on the effect of empowering education in self-care.
