Factors Associated With the Occurrence of Adverse Effects Resulting From Hypodermoclysis in Older Adults in Palliative Care: A Cohort Study

Abstract

This study aimed to analyze the factors associated with local adverse effects resulting from hypodermoclysis in older adult patients in palliative care. The study involved 127 older adults undergoing palliative care at a hospital in southeastern Brazil. Data collection was performed from August to November 2019. Patients aged 60 years or older, with a prescription for hypodermoclysis at the time of admission and who were not receiving hypodermoclysis at the time of admission, were included. Data collected included sociodemographic, clinical, pharmacotherapeutic, and adverse effects of hypodermoclysis administration. Most participants were women (59.0%), with a mean age of 78.5 years. Frailty was the most prevalent diagnosis (26.8%), and 80.2% of patients were in the end-of-life stage. There was an incidence of 24.0% of adverse events, with catheter obstruction and swelling in the surrounding area of the hypodermoclysis site being the most frequent at 11.3% and 8.5%, respectively. Ondansetron administration by hypodermoclysis was 3 times more likely to have an adverse effect compared to not using this drug. In contrast, a protective factor was evident with the administration of 0.9% sodium chloride, which contributed to the reduction of complications. The occurrence of adverse effects from hypodermoclysis in the study population of older adults in palliative care was low.
