Nursing Support for Constipation in Palliative Care Units in Japan: A Multisite Cross-Sectional Study

TL;DR

This study explores how often nurses in Japan's palliative care units use various methods to help cancer patients with constipation in their final months and weeks.

Contribution

The study provides new insights into the underutilization of specific nursing interventions for constipation in palliative care.

Findings

Warm compresses were the most frequently used nursing support for constipation.

Auricular acupressure and abdominal massage with essential oils were rarely used.

Self-management education was more common in the final weeks of care.

Abstract

This study investigated the frequency with which nursing support for constipation is provided for patients with cancer during the prognostic months and weeks.

An online cross-sectional survey was conducted anonymously among registered nurses in palliative care units across Japan. The frequencies of providing six types of nursing support (abdominal massage with essential oils, abdominal acupressure, auricular acupressure, self-management education, abdominal massage, and warm compresses) were surveyed.

Data were obtained from 539 nurses (response rate: 22.3%) from 162 facilities. The most frequently provided support was warm compression; the least frequently provided supports were auricular acupressure, abdominal massage with essential oils, and abdominal acupressure. In the prognostic weeks only, self-management education followed these support types.

The investigation found that the six types of support were rarely implemented for relieving constipation in patients with cancer. Future research should investigate the factors hindering the provision of these supports.

Introduction

Constipation is an uncomfortable symptom experienced by patients with cancer, which reduces their quality of life.^1,2^ Constipation is managed by pharmacological and nonpharmacological therapies. However, few reports on effective nonpharmacological therapies for constipation exist.^3–7^ In a scoping review of nursing support types to relieve constipation in patients with cancer, aroma-based massage to the abdomen, auricular acupressure, abdominal acupressure, and self-management education were identified.^8^ Moreover, abdominal massage and acupressure have recently been shown to be effective in the management of opioid-induced constipation (OIC).^9,10^ In Japan, warm compresses are empirically used to relieve constipation and increase intestinal peristalsis, promote defecation and evacuation, and improve constipation.^11,12^

Nurses play an important role in providing nonpharmacological therapy. However, the nursing support that is provided based on prognosis is unclear. This study surveyed how frequently the nursing support types identified in previous studies are provided in palliative care units (PCUs) in Japan. By investigating the extent to which nursing support for constipation is provided based on prognosis, the gap between evidence and clinical practice can be identified. Moreover, it would provide useful information to nurses providing palliative care and contribute to future nursing support.

Purpose

This study investigated the frequency with which nursing support for constipation is provided by registered nurses during the prognostic months and weeks in PCUs across Japan.

Methods

Study design

A multisite online cross-sectional survey was conducted anonymously among registered nurses in PCUs across Japan.

Participant recruitment

First, a document explaining the research was sent to the administrators of all facilities with PCUs in Japan, and their participation was requested. After obtaining consent, a document describing the research was mailed to the nurses in the facilities, and individual access to an online questionnaire was granted. Only nurses who agreed to participate in the study completed the online questionnaire. Data were collected between October 2023 and March 2024 from the nurses who provided direct care in PCUs. The nurses completed the survey anonymously using LimeSurvey Cloud (LimeSurvey GmbH, cf. https://www.limesurvey.org/ja).

Measurements

The survey was conducted based on the scoping review that aimed to extract evidence on nursing support to provide constipation relief to terminally ill patients with cancer.^6^ The identified support types were abdominal massage with essential oils, abdominal acupressure, auricular acupressure, and self-management education.^6^ In addition, a preliminary survey of nine nurses with PCU experience identified nursing support for abdominal massage and warm compresses. The questions described six types of nursing support and asked the same questions based on prognostic months and weeks. For example: “1. Based on your experience in providing abdominal massage for constipation to promote bowel movement, how much would you provide it in the following conditions: 1–1. The patient’s “prognostic months” situation? 1–2. The patient’s “prognostic weeks” situation?” All questions were scored on a Likert scale with the following options: “1. Never,” “2. Seldom,” “3. Sometimes,” “4. Frequently,” and “5. Always.”

In addition, demographic data, such as sex, age, educational background, qualifications, years of nursing experience, and years of PCU experience, were collected.

Statistical analysis

Descriptive statistics were used to analyze demographic information and nursing support frequencies. EZR, a component of the R software (Saitama Medical Center, Jichi Medical University, Saitama, Japan), was used for statistical analysis.^13^

Ethical considerations

This study was approved by the relevant clinical research ethics review committee (blinded for review). All the participants provided informed consent by responding affirmatively to a consent form. Reporting followed the Strengthening the Reporting of Observational Studies in Epidemiology guidelines.^14^

Results

A request was sent to all 389 palliative care wards in Japan, of which 162 participated. A total of 2448 nurses were requested to complete the survey, with 539 responding (valid response rate: 22.3%). The participants’ demographics are shown in Table 1. Most were female (94.8%), with a mean age of 42.3 years (standard deviation [SD]: 9.8 years), and attended a vocational nursing school (including a junior college) (n = 456; 84.6%). The mean nursing experience was 18.6 years (SD: 9.6 years) and that in PCUs was 4.8 years (SD: 4.3 years). Most participants with specialty certifications were registered palliative care nurses (n = 29; 5.3%).

Nursing support for constipation in patients with cancer, based on the prognosis in months and weeks, is shown in Table 2. Auricular acupressure was the least frequently implemented of the six types of support. The sum of the percentages of each nursing support based on prognosis and differences from month to week are shown in Table 3. The highest percentage of registered nurses who reported implementing interventions “frequently or more” provided warm compression; the lowest percentage implementing interventions “never or less” provided auricular acupressure, abdominal massage with essential oils, and abdominal acupressure. In addition, in the prognostic weeks only, self-management education followed these support types.

Discussion

This study investigated nursing support for relieving constipation in patients with cancer in Japanese PCUs, with a focus on prognosis. We explored the differences in the frequency with which each type of nursing support is implemented in practice. The trends in nursing support were considerably similar for patients with a prognosis of weeks and months.

Auricular acupressure, abdominal massage with essential oils, and abdominal acupressure were rarely provided in both months and weeks of prognosis. The effectiveness of these nursing support types has been reported in the existing literature.^6^ Applicability of auricular acupressure was rated differently in an expert Delphi survey conducted prior to this study regarding application to patients with a prognosis of weeks.^15^ This may have been because of low access to knowledge and information and required time for support to become effective. The results suggest that access to such techniques is limited in Japan.

Warm compression was the most frequently provided support; however, it was provided only by ∼40% of all nurses, and the frequency of nursing practice was not high. Warm compression improves constipation and quality of life in women.^16^ It is an empirically common form of support in Japan but may not be used in other countries. Similarly, abdominal massage is an effective approach to relieve constipation in patients with OIC and increase bowel movements.^9^ These nursing support types are not expensive, are easy to provide, and can be offered in addition to pharmacotherapy.

Self-management education was sometimes provided in the prognosis months, but rarely in the prognosis weeks. In a previous study, self-management education was provided to patients undergoing chemotherapy for breast cancer who maintained their activities of daily living.^17^ The program consisted of abdominal massage, abdominal muscle stretching, and education on proper defecation positions. Abdominal muscle stretching was difficult to implement in prognostic weeks. Education regarding proper defecation position is also recommended by the Multinational Association of Supportive Care in Cancer and is useful for patients with a prognosis of weeks.^4^ Therefore, depending on the patient’s medical condition and status, it is necessary to promote self-management education to relieve constipation.

Effective nursing support for constipation is gradually being identified; however, knowledge of care providers and support systems in facilities is necessary to provide effective nursing support in clinical settings. In the future, it will be important to investigate the factors that make it difficult to provide nursing support to relieve constipation.

Limitations

This study had several limitations. First, this survey was conducted online, and the response rate was low, possibly introducing a bias toward nursing practices of respondents who were enthusiastic about implementing the interventions. Second, nursing support such as hot compresses may be influenced by cultural backgrounds and is rarely implemented outside Japan. Although there are few studies on nursing support that are effective in relieving constipation, there may be other types of nursing support that are empirically implemented globally.

Conclusion

This study investigated nursing support for relieving constipation in patients with cancer in Japanese PCUs, with a focus on prognosis. The study found that six types of support for relieving constipation were rarely implemented in palliative care wards in Japan. Future research is needed to investigate the factors hindering these nursing support types for constipation relief.
