Perceptions of the role of the hospital palliative care team.

AIM: The aim of this study was to understand staff perceptions of the role of the hospital palliative care team and to identify knowledge and confidence levels of general staff caring for patients with palliative care needs. METHOD: A survey questionnaire tool was used with a response rate of 51 per cent. Participants included nurses, health care assistants and doctors. RESULTS: The study highlighted several misconceptions about the role of the palliative care team, but demonstrated that the clinical staff surveyed were confident in their palliative care skills, with the exception of discharge planning, despite the fact that only 26 per cent of nurses reported having undergone training in palliative care. It identified that HCAs felt confident in caring for dying patients yet had little confidence in dealing with distressed relatives or speaking to patients and families about death. It was also interesting to note that trained nurses felt confident in their symptom control skills, and they rated training in this area as one of the top priorities. CONCLUSION: The findings have considerable implications for palliative care services. Professional education should continue to focus primarily on symptom control and communication skills training, but stress management training should be considered. Staff need to be clear about how to obtain advice and what support is available for cancer patients. Further research is required to understand the needs of HCAs and potential models for education and support.

Orthostatic modification of ventilatory dynamic response to carbon dioxide perturbations.

In order to determine whether changes in ventilatory control contribute to the observed decrease in arterial partial pressure of carbon dioxide (PaCO(2)) during head up tilt, we assessed ventilatory dynamic sensitivity to changes in PaCO(2) during supine and 70 degrees passive head up tilt. In 24 adult normals, we stimulated the ventilatory control system by switching inspired CO(2) between room air and room air+5% CO(2) in a pseudo random binary sequence. A Box-Jenkins model was used to compute ventilatory response to CO(2). Airflow, CO(2), non-invasive beat by beat blood pressure, ECG and cerebral blood flow velocity (Doppler) were recorded. During tilt, sensitivity of the ventilatory controller to CO(2) disturbance increased (from 0.45 to 0.72 L/min/mm Hg, p<0.005); minute ventilation increased (7.63 to 8.47 L/min, p<0.01), end tidal CO(2) (ETCO(2)), cerebral blood flow velocity (CBF) and baroreflex sensitivity decreased (46.9 to 42.9 mm Hg, p<0.001; 84.9 to 72.9 cm/s, p<0.001; and 17.6 to 5.5 ms/mm Hg, p<0.001). The primary observation from our study was that the sensitivity of ventilatory control system to perturbations in ETCO(2) increased during tilt. Taken together with decrease in mean levels of ETCO(2) and an increase in minute ventilation, these results suggest that during tilt, a change in the regulated level or 'set point' of PaCO(2) may occur.
