Abstract
OBJECTIVE: To evaluate the time to hospitalisation and baseline factors associated with pneumonia/choking in Parkinson's Disease (PD) patients.
BACKGROUND: Although dysphagia and pneumonia are common problems in PD, scarce research has been performed.
METHODS: A total of 194 PD patients who underwent a VFS evaluation were retrospectively selected. The mode of feeding and admissions for pneumonia/choking were analyzed. Baseline clinical and demographic variables were compared between feeding groups. Kaplan-Meier survival analysis was performed to estimate time to pneumonia/choking. Clinical variables significantly associated with pneumonia/choking free survival were identified using Cox regression.
RESULTS: Hospitalisation for pneumonia/choking occurred in 89 out of 194 patients, with the highest admission rate in rejected enteral feeding group (66.7%), followed by enteral feeding (61.8%) and oral feeding (38.8%) groups. The estimates of median time to event were 11, 14, and 47 months for rejected enteral feeding, enteral and oral feeding groups respectively (log-rank test p < 0.001). The rejected enteral feeding group had the highest risk of pneumonia/choking (HR 4.61, 95%CI:2.33-9.08, p < 0.001), followed by enteral feeding group (HR 2.29, 95%CI:1.25-4.19, p = 0.007), when compared to oral feeding group after adjusting for possible confounders. A stepwise Cox regression showed that the rejected enteral feeding (HR 4.89, 95%CI:2.19-10.88, p < 0.001), enteral mode of feeding (HR 2.43, 95%CI:1.11-5.32, p = 0.026), and Charlson weighted index of co-morbidity (HR 1.27, 95%CI:1.03-1.58, p = 0.028) were independently associated with higher hazard of pneumonia/choking.
CONCLUSIONS: Compliance to feeding recommendations is important to reduce the risk of hospitalisation for pneumonia/choking. The recommended mode of feeding and comorbidity index was significantly associated with pneumonia/choking risk.
