Establishing reliability and validity of a constipation risk assessment scale

Prevalence and Risk Factors of Constipation in Trauma Patients: A Prospective Cohort Study

BACKGROUND

Hospitalized patients are well described as having a high prevalence of constipation. While the risks associated with constipation in trauma patients are well known, the prevalence rate is not.

OBJECTIVE

This study aims to measure the prevalence of constipation and associated risk factors in trauma patients.

METHODS

This study is a single-center analytic cross-sectional study on constipation in hospitalized trauma patients aged 18-65 years, admitted from January 2021 to July 2021 to the trauma service at The Royal Melbourne Hospital, a Level I major trauma and teaching hospital servicing the state of Victoria, Australia. Exclusion criteria include patients with traumatic brain injury, blunt or penetrating abdominal or spinal injuries, pregnancy, and gastrointestinal comorbidities.

RESULTS

A total of N = 99 patients were studied, of which n = 78 (78.8%) were male with a median (interquartile range) age of 46 years (33-58). The overall prevalence of constipation was 76%. The univariate analysis demonstrated higher constipation rates in males and patients with multisystem injuries. However, in the multivariate analysis, mode of toileting and mobility were not associated with constipation after adjusting for confounding factors.

CONCLUSION

This study demonstrated a high prevalence of constipation in all trauma patients. There is a strong association between the development of constipation in patients with multisystem injuries when compared to those with single system.

The Effect of Abdominal Massage on Discharge and Ventilator-Associated Pneumonia in Enterally Fed Patients Connected to Mechanical Ventilation: A Randomized Controlled Study

PURPOSE

The present research was conducted to reveal the impact of abdominal massage on enteral nutrition-induced ventilator-associated pneumonia and the gastrointestinal system in mechanically ventilated patients.

MATERIALS AND METHODS

The present research is a prospective, randomized, controlled clinical trial. This study was completed with 63 patients (31 in the experimental group and 32 in the control group). Data collection was performed using a patient information form, a patient follow-up form, and the Bristol Stool Scale. After patients were under mechanical ventilation for 48 hours, the data collection tools were filled out twice a day for 3 days by visiting the mechanical ventilation patients. The experimental group received 15 minutes of abdominal massage twice a day before nursing care was delivered in the morning and the evening.

RESULTS

According to the intergroup evaluations, the experimental group had lower gastric residual volume and abdominal distension, types of stool closer to normal, and higher defecation frequency. Differences between the groups were statistically significant (P < .05). In accordance with the intragroup evaluations, the experimental group had lower gastric residual volume, abdominal distension, and ventilator-associated pneumonia. The difference between the groups was revealed to be statistically significant (P < .05).

CONCLUSION

Abdominal massage reduces ventilator-associated pneumonia development to a statistically significant degree. Furthermore, it decreases gastric residual volume and abdominal distension, causes stools to be closer to the normal/ideal stool, increases defecation frequency, and regulates bowel movements and excretion (P < .05).

Validation of the Constipation Risk Assessment Scale (CRAS) in Chinese cancer patients

PURPOSE

The Constipation Risk Assessment Scale (CRAS) is a valid tool for predicting the risk of developing constipation. This study aimed to translate the CRAS into Chinese and evaluate its psychometric properties in Chinese cancer patients.

METHOD

The CRAS was translated into Chinese following standard forward- and back-translation procedures. Scale and item indices were calculated for content validity (S-CVI; I-CVI). In total, 175 cancer patients were assessed with the CRAS on the first day of antitumour treatment, of whom 145 were submitted to the predictive validity test, and their defecation pattern, stool consistency, and ease of defecation were assessed for one week. A receiver operating characteristic (ROC) curve was used to describe the prediction accuracy of CRAS-C for constipation. Reliability was evaluated by means of an interrater reliability test using the intraclass correlation coefficient (ICC) in 30 patients.

RESULTS

The S-CVI was 0.99, and for each item, the I-CVI was 0.80-1.00. The area under the curve of CRAS-C was 0.722 (95% CI, 0.631-0.812). A CRAS-C score ≥11 indicated a high constipation risk, and a score <11 indicated a low constipation risk. The sensitivity and specificity were 0.887 (95% CI, 0.763-0.953) and 0.500 (95% CI, 0.376-0.624), respectively, and the positive predictive value and negative predictive value were 0.588 (95% CI, 0.472-0.695) and 0.846 (95% CI, 0.688-0.936), respectively. The ICC between the two raters for the total CRAS-C score was 0.963, and the ICC in the four subscales was 0.843-0.955.

CONCLUSIONS

The CRAS-C demonstrated favourable content validity, predictive validity and interrater reliability. It can be used in the identification of subjects at risk of constipation and the development of constipation prevention programmes in Chinese cancer patients.

Effect of abdominal massage on bowel evacuation in neurosurgical intensive care patients

BACKGROUND

There are many factors, which affect the bowel evacuation of neurosurgical intensive care unit (NICU) patients, resulting in constipation.

AIM AND OBJECTIVES

The aim of this study was to investigate effect of abdominal massage on bowel evacuation and the risk of constipation in NICU patients.

DESIGN

A prospective, randomized-controlled clinical trial.

METHODS

The sample of this study included 80 NICU patients. The patients were randomly assigned to abdominal massage and control groups. The constipation risk of all the patients was assessed with Constipation Risk Assessment Scale (CRAS). The patients in the abdominal massage group received a total of 30 minutes of massage, 15 minutes every morning and evening, until the first defecation. The bowel sounds of all patients in the abdominal massage and control groups were assessed on a daily basis. The days when bowel sounds were heard and the first defecation took place were recorded in a Bowel Evacuation Form.

RESULTS

The risk of constipation was higher in the patients in the abdominal massage (CRAS score 19.02 ± 1.81) and control groups (CRAS score 20.45 ± 2.61). The time of return of bowel sounds and the time of the first defecation were earlier in the abdominal massage group, compared to the control group (P < .05). In the control group, there was a weak correlation (P = .004) between the CRAS score and the time of return of bowel sounds, while there was a moderate correlation between the CRAS score and the time of the first defecation (P < .001).

CONCLUSION

Our study results show that the risk of constipation is high in NICU patients, and abdominal massage is an effective nursing intervention to shorten the time of return of bowel sounds and the time of the first defecation.

RELEVANCE TO CLINICAL PRACTICE

Nurses can safely apply abdominal massage to improve bowel evacuation in NICU patients.

Constipation in Peritoneal Dialysis Patients

Constipation in peritoneal dialysis (PD) is an infrequent but potentially serious condition affecting the mechanical properties of dialysis techniques and predisposing to bacterial intestinal translocation and eventual enteric peritonitis. Despite the importance of the problem, published literature is scarce, consisting mostly of uncontrolled single-center trials. This inconsistency may be attributed to the large number of clinical, radiological, and endoscopic tools that have been used in the studies with a lack of generally accepted core primary outcomes.

The current narrative review discusses the pathophysiological associations between chronic kidney disease, PD, and constipation with related complication.

[Consensus approach: Prior to the construction of an evaluation scale of risk constipation patients hospitalized for nursing practice]

BACKGROUND

Constipation is a frequent issue during hospitalization. Multiple causes such as the existence of irregular habits, lack of exercise as well as medical history have been identified. Drugs such as strong painkillers, central nervous system therapies and treatments of the digestive tract are a major cause of constipation. Additionally, unbalanced diet, fluid deficiency, and anxiety may aggravate constipation. The consideration of all these risk factors being under the responsibility of nurses. The difficulty to take into account such a multifactorial aetiology in nursing practice and the fact that there is no easy to use and validated tool to assess the risk of constipation in current nurse practice has led us to consider the development of a Risk Assessment scale of Constipation in Patient Hospitalized (ERCoPH) to facilitate preventive management of this trouble. We present here the first step of the elaboration of this scale, the identification of risk factors through a consensus approach after a systematic literature review.

METHODS

The key informants consensus-based approach proposed by Pineault and Daveluy is based on five steps: (1) a literature review to identify risk factors for constipation; (2) the elaboration of a questionnaire containing the factors identified in the first step; (3) pre-select a panel of experts; (4) submission the questionnaire to the panel; (5) analysis the results of the consensus survey. Only factors that received a rating>6 by at least 80 % of the experts were retained.

RESULTS

The systematic literature review identified 69 risk factors submitted to the 23 experts of the panel. Fifteen risk factors were retained after analyzing the answers of the experts. The Scientific Committee added eight risk factors because of their importance in the literature and decided to group together some factors of the same domain.

CONCLUSION

A total of 19 risk factors were selected and grouped by major class (age, physical activity, medication, social data, food/hydration, medical and surgical history and environmental data). These factors have been tested among 300 patients enrolled in different clinical settings as part of the construction and validation of ERCoPH.

Constipation in specialized palliative care: factors related to constipation when applying different definitions

CONTEXT

For patients in palliative care, constipation is primarily a result of opioid treatment. Impacts from other factors related to constipation in palliative care are rarely studied.

OBJECTIVES

The aim was to identify factors related to constipation in patients in palliative care, and then to compare these factors between patients with different types of constipation and patients without constipation.

METHODS

Cross-sectional data on constipation was collected with a 26-item questionnaire from 485 patients in 38 specialist palliative care units in Sweden. Three different constipation groups were used; MC ONLY, PC ONLY, and MC & PC. Logistic regression analyses were used to calculate odds ratios.

RESULTS

Patients with <3 defecations/week, MC ONLY, (n = 36) had higher odds of being hospitalized, bed-restricted, in need of personal assistance for toilet visits, and of having a poor fluid intake. Patients with the perception of being constipated, PC ONLY, (n = 93) had higher odds of having poor appetite, hemorrhoids, hard stool, more opioid treatment, less laxative treatment and of being more dissatisfied with constipation information. Patients with both <3 defecations/week and a perception of being constipated, MC & PC, (n = 78) had higher odds of having cancer- disease.

CONCLUSION

There were several significant factors related to constipation with higher odds than opioid- treatment, for patients in palliative care, such as; hard stool, cancer diagnosis, dissatisfaction with information, low fluid intake, hemorrhoids, bed restriction, hospitalization, and need of personal assistance for toilet visits.

Constipation Risk in Patients Undergoing Abdominal Surgery

Background:

Problems regarding bowel elimination are quite common in patients undergoing abdominal surgery.

Objectives:

To determine constipation risk before the surgery, bowel elimination during postoperative period, and the factors affecting bowel elimination.

Patients and Methods:

This is a cross-sectional study. It was conducted in a general surgery ward of a university hospital in Zonguldak, Turkey between January 2013 and May 2013. A total of 107 patients were included in the study, who were selected by convenience sampling. Constipation Risk Assessment Scale (CRAS), patient information form, medical and nursing records were used in the study.

Results:

The mean age of the patients was found to be 55.97 ± 15.74 (year). Most of the patients have undergone colon (37.4%) and stomach surgeries (21.5%). Open surgical intervention (83.2%) was performed on almost all patients (96.3%) under general anesthesia. Patients were at moderate risk for constipation with average scores of 11.71 before the surgery. A total of 77 patients (72%) did not have bowel elimination problem during postoperative period. The type of the surgery (P < 0.05), starting time for oral feeding after the surgery (P < 0.05), and mobilization (P < 0.05) were effective on postoperative bowel elimination.

Conclusions:

There is a risk for constipation after abdominal surgery. Postoperative practices are effective on the risk of constipation.
