RESUMO
Background: Global trigger tool (GTT) was developed for identification of patient harm. In palliative patients deterioration can be expected, and there are no data on whether cases classified as "patient harm" actually represents a potential for improved patient safety. Objectives: The primary aim was to test the performance and suitability of GTT in palliative care patients. The secondary aim was to pilot triggers for substandard palliative care. Design and Measurements: GTT was applied in 113 consecutive patients at a palliative ward at a Norwegian university hospital. Cases of patient harm were further evaluated to decide if the case was (a) a natural part of the disease trajectory or (b) a foreseeable consequence of treatment decisions. Potential triggers for substandard palliative care were tested. Results: Two hundred twelve triggers (1.9 per hospitalization) and 26 cases of patient harm were identified. The positive predictive value (PPV) for identifying patient harm was 0.12. The most prevalent harm was pressure ulcers (8.8%). Of the 26 cases of patient harm, 6 cases were a natural part of the disease trajectory and 10 consequences of treatment decisions. In 21 (18%) patients triggers being piloted for substandard palliative care were present, identifying 9 cases of substandard palliative care. The highest PPV (0.67) was observed for "Cessation of antibiotics less than 5 days before death." Conclusions: With the exception of pressure ulcers, GTT triggers were infrequent or had a very poor PPV for patient harm. Triggers related to overtreatment might be suitable for identifying substandard palliative care.
