Provision of food and fluids in terminal care: A sociological analysis

The educational intervention remarkably improved nurses' knowledge and attitudes regarding supplying terminal cancer patients with ANH. As for the changes in the behavioral intentions, it requires long-term moral and ethical training and communication. The results of this research emphasized the importance of educational interventions, which should be considered seriously in future reference nursing education program.

Effects of educational intervention on nurses’ knowledge, attitudes, and behavioral intentions toward supplying artificial nutrition and hydration to terminal cancer patients

Chiu

et al. 2008

“…Feeding has powerful symbolic and social significance [17], especially in Asia. Difficulty in eating or drinking often leads to anxiety in the patient's loved ones, who worry that the patient will starve to death and therefore become a "starving soul" after death.…”

Nutrition and hydration for terminal cancer patients in Taiwan

Chiu

Chuang

et al. 2002

Many medical professionals are still confused when facing the reduction of food or fluid intake in terminal cancer patients. The aim of this study was to assess the frequency and causes of the inability of eating or drinking in terminal cancer patients and to investigate the use of artificial nutrition and hydration (ANH); the frequency, type, and the extent to which staff found ANH to be ethically justified. Three hundred forty-four consecutive patients with terminal cancer admitted to a palliative care unit in Taiwan were recruited. A structured data collection form was used daily to evaluate clinical conditions, which were analyzed at the time of admission, 1 week after admission and 48 h before death. One hundred thirty-three (38.7%) of the 344 patients were unable to take water or food orally on admission; the leading cause was GI tract disturbances (58.6%). This impaired ability to eat or drink had become worse 1 week after admission (39.1%, P<0.01) and again 48 h before death (60.1%, P<0.001). The total rate of ANH use declined significantly, from 57.0% to 46.9% 1 week after admission ( P<0.001), but rose again to the same level as at admission in the 48 h before death (53.1%, P=0.169). Parenteral hydratation could be reduced significantly 1 week after admission ( P<0.05), but no reduction was possible in the 48 h before death; nor was it possible to reduce the nutrition administered. Multiple Cox regression analysis shows that the administration of ANH, either at admission or 2 days before death, did not have any significant influence on the patients' survival (HR: 0.88, 95% CI: 0.58-1.07; HR: 1.03, 95% CI: 0.76-1.38). In conclusion, sensitive care and continuous communication will probably lessen the use of ANH in terminal cancer patients. We have found it easier to reduce artificial hydratation than artificial nutrition, which corresponds to local cultural practice. Whether or not ANH was used did not influence survival in this study. Thus, the goals of care for terminal cancer patients should be refocused on the promotion of quality of life and preparation for death, rather than in simply making every effort to improve the status of hydratation and nutrition.

“…On the other hand, existing evidence about the role of dehydration in sensation of thirst in terminal patients is at most preliminary, despite recent aggressive discussion in the palliative care literature [3,4,11,18,21,25]. Whereas several empirical studies have demonstrated that biochemical dehydration is not correlated with the symptom [5,13,23,24], these studies have considerable methodological limitations [31].…”

Determinants of the sensation of thirst in terminally ill cancer patients

Morita

Tei

Tsunoda

et al. 2001

While a sensation of thirst causes severe distress for a certain proportion of cancer patients in the terminal stage, the factors contributing to this symptom have not been established. To clarify the association between sensation of thirst and medical factors, especially dehydration, a cross-sectional observational study was performed on terminally ill cancer patients receiving inpatient hospice care. On admission to a palliative care unit, 88 consecutive patients underwent blood sampling and were requested to rate the intensity of thirst on a visual analogue scale (VAS). Physicians prospectively evaluated factors that might potentially be contributing to the symptom. The mean VAS score for thirst was 5.0+/-2.8, and 18% of the patients complained of severe thirst with a VAS score of > or = 8. No significant correlations were observed between the VAS score for thirst and the values of total protein, blood urea nitrogen (BUN), creatinine, sodium, osmolality, hematocrit, atrial natriuretic peptide (ANP), and biochemical dehydration defined by the levels of BUN, creatinine, sodium and osmolality. On the other hand, dehydration defined by ANP level (< or = 15 pg/ml), hyperosmolality (> or = 300 mosmol/kg), gastrointestinal cancer, survival, performance status, oral intake, vomiting, and stomatitis were significantly associated with the severity of thirst. In addition, mouth breathing and opioids were determined to be a potential clinical cause of severe thirst when a retrospective chart review was carried out. In conclusion, sensation of thirst is a frequent symptom in terminally ill cancer patients and is associated with dehydration, hyperosmolality, poor general conditions, stomatitis, oral breathing, and opioids. Careful assessments and treatment of underlying causes is important to alleviate patients' distress.
