Constipation in Specialized Palliative Care: Prevalence, Definition, and Patient-Perceived Symptom Distress

Psychometric evaluation of the Chinese version of the Elderly-Constipation Impact Scale: a translation and validation study

OBJECTIVE

The objective of this study was to translate the Elderly-Constipation Impact Scale into Chinese and to examine its reliability and validity in a population of older people suffering from chronic constipation.

METHODS

In this study, the scale was paraphrased, back-translated, cross-culturally adapted and pre-experimented using the Brislin double translation-back-translation method to create the initial Chinese version of the Elderly-Constipation Impact Scale. A convenience sampling method was used to select 564 study participants who met the inclusion and exclusion criteria in Liaoning and Shanxi, China, to evaluate the reliability and validity of the scale. General information about the study population was using descriptive statistics; item analysis was used to screen the items of the scale. Content validity, exploratory factor analysis, and validation factor analysis were chosen to validate the scales; internal consistency, spilt-half reliability and retest reliability were used determine the reliability of the measurement scales.

RESULTS

The Chinese version of the Elderly-Constipation Impact Scale contains 7 dimensions and 21 items. The Cronbach's alpha coefficient for the total scale was 0.901 and the range of Cronbach's alpha values for each dimension was 0.707 to 0.918. The split-half reliability of the scale was 0.736 and the retest reliability was 0.763. The exploratory factor analysis showed a KMO value of 0.873 and a Bartlett's spherical test X² value of 3499.978 (p < 0.001). A total of seven common factors were extracted, namely daily activities, treatment satisfaction, lack of control of bodily function, diet restriction, symptom intensity, anxiety and preventive actions, with a cumulative variance contribution of 77.813%. Each item had a loading value > 0.4 on its common factor. In the validation factor analysis, the model fit results were X² / df = 1.886, GFI = 0.910, AGFI = 0.874, PGFI = 0.654, IFI = 0.955, TLI = 0.942, CFI = 0.954, RMSEA = 0.056 and PNFI = 0.718. The model fit indicators were all within acceptable limits.

CONCLUSION

The Chinese version of the E-CIS has good reliability and validity in the chronic constipation population of elderly individuals. The results of the questionnaire can effectively and comprehensively reflect the impact of chronic constipation on the quality of life of elderly individuals. It provides a meaningful reference for identifying targets for intervention.

Proposed Criteria for Constipation in Palliative Care Patients. A Multicenter Cohort Study

Although constipation is one of the most frequently reported symptoms in palliative care, there is no widely accepted definition of constipation and none suitable for patients unable to self-report or express symptoms. This study aimed to verify the objective and subjective symptoms of constipation to develop a diagnostic algorithm for constipation, which is also feasible in unconscious patients. In a pooled analysis of two observational studies, 369 out of 547 adult end-stage cancer patients met the inclusion criteria. The patient-reported difficulty of defecation correlated with observable measures, such as days since last bowel movement, and frequency of bowel movements. Difficulty became at least moderate when there were no bowel movements for ≥2 days, or the frequency of bowel movements was ≤3 per week. The diagnostic algorithm, comprising these three symptoms offers a simple, rapid, and comprehensive tool for palliative care, independent of the patient's state of consciousness. A clinical trial is necessary to confirm its validity and usefulness.

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.
