Integrated palliative care: triggers for referral to palliative care in ICU patients.

INTRODUCTION: Palliative care within intensive care units (ICU) benefits decision-making, symptom control, and end-of-life care. It has been shown to reduce the length of ICU stay and the use of non-beneficial and unwanted life-sustaining therapies. However, it is often initiated late or not at all. There is increasing evidence to support screening ICU patients using palliative care referral criteria or "triggers". The aim of the project was to assess the need for palliative care referral during ICU admission using "trigger" tools. METHODS: Electronic record review of cancer patients who died in or within 30 days of discharge from oncology ICU, between 2016 and 2018. Patients referred to palliative care before or during ICU admission were identified. Three sets of palliative care referral "triggers" were applied: one that is being tested locally and two internationally derived tools. The proportion of patients who met any of these triggers during their final ICU admission was calculated. RESULTS: Records of 149 patients were reviewed: median age 65 (range 20-83). Most admissions (89%) were unplanned, with the most common diagnoses being haemato-oncology (31%) and gastrointestinal (16%) cancers. Most (73%) were unknown to palliative care pre-ICU admission; 44% were referred between admission and death. The median time from referral to death was 0 day (range 0-19). On ICU admission, 97-99% warranted referral to palliative care using locally and internationally derived triggers. CONCLUSION: All "trigger" tools identified a high proportion of patients who may have warranted a palliative care referral either before or during admission to ICU. The routine use of trigger tools could help streamline referral pathways and underpin the development of an effective consultative model of palliative care within the ICU setting to enhance decision-making about appropriate treatment and patient-centred care.

RATIONAL USE OF SERUM TUMOUR MARKERS IN DIAGNOSTICS AND TREATMENT OF SOLID TUMOURS. / RACIONALNA PRIMJENA SERUMSKIH TUMORSKIH BILJEGA U DIJAGNOSTICI I LIJECENJU SOLIDNIH TUMORA.

Optimal management of patients with solid tumors, depending on the tumour type, includes measurement of serum tumour markers levels. Serum tumour markers are heterogeneous molecules with concentrations elevated in persons with solid tumours, but could also be found in small amounts in plasma of healthy individuals. Elevated plasma concentrations are caused by cell changes, necrosis, changed expression or secretion of different molecules. In some tumour types tumour cells by themselves could stimulate other cells to secrete particular molecules. There are several serum tumour markers in the routine clinical praxis: CEA, CA 19-9, CA15-3, CA 125, CYFRA, NSE, PSA, HCG, AFP, LDH, thyreoglobulin. There are also several serum tumour markers in experimental use, waiting to be included into the routine clinical use. National Academy of Clinical Biochemistry (NACB) practice guidelines for use of tumour markers in clinical practice are designated to encourage more appropriate use of serum tumour marker tests by general medicine practitioners, surgeons, oncologists, and other health care professionals giving care to patients with solid tumours.
