[Frequency of symptoms and drug treatment among dying patients in the last 24 hours of life at Landspitali - The National University Hospital of Iceland and in nursing homes].

INTRODUCTION: The purpose of this study was to evaluate the frequency of 5 common symptoms and drug treatments prescribed and given in the last 24 hours of life in 11 medical units at Landspitali National University Hospital of Iceland (LUH) and in 7 nursing homes (NH). MATERIAL AND METHODS: Data was collected retrospectively from 232 charts of patients who died in 2012, using documentation in the Liverpool Care Pathway (LCP) and the medication management system. RESULTS: About half of the patients died at LUH with similar gender ratio but 70% of patients in NH were women. The LCP was used for 50% of all deaths at LUH and 58% in NH. In 45% of all deaths LCP was used for 24 hours or less. The most common symptoms were pain (51%), agitation (36%) and respiratory tract secretions (36%). Frequency of symptoms was similar between institutions and age groups. Cancer patients had significantly higher incidence of agitation and were prescribed and given higher doses of morphine compared to other groups. Regular medication for agitation was haloperidol (45%), diazepam (40%) and midazolam (5%). Close to 70% of the patients were treated with a scopolamin patch for death rattle. CONCLUSION: A large number of patients have symptoms in the last 24 hours of life both in hospital and in nursing homes. Symptom control can be improved by adjusting morphine doses to patients need, using regular doses of benzodiazepine for agitation and better use of anticholinergic medication for death rattle. Key words: symptoms, medication, dying patients, last 24 hours of life, hospital, nursing homes. Correspondence: Svandis Iris Halfdanardottir, svaniris@landspitali.is.

Motor subtypes of postoperative delirium in older adults.

HYPOTHESIS: Increased knowledge about motor subtypes of delirium may aid clinicians in the management of postoperative geriatric patients. DESIGN: Prospective cohort study defining preoperative risk factors, outcomes, and adverse events related to motor subtypes of postoperative delirium. SETTING: Referral medical center. PATIENTS: Persons 50 years and older with planned postoperative intensive care unit (ICU) admission following an elective operation were recruited. MAIN OUTCOME MEASURES: Before surgery, a standardized frailty assessment was performed. After surgery, delirium and its motor subtypes were measured using the validated tools of the Confusion Assessment Method-ICU and the Richmond Agitation-Sedation Scale. Statistical analysis included the univariate t and χ(2) tests and analysis of variance with post hoc analysis. RESULTS: Delirium occurred in 43.0% (74 of 172) of patients, representing 67.6% (50 of 74) hypoactive, 31.1% (23 of 74) mixed, and 1.4% (1 of 74) hyperactive motor subtypes. Compared with those having mixed delirium, patients having hypoactive delirium were older (mean [SD] age, 71 [9] vs 65 [9] years) and more anemic (mean [SD] hematocrit, 36% [8%] vs 41% [6%]) (P = .002 for both). Patients with hypoactive delirium had higher 6-month mortality (32.0% [16 of 50] vs 8.7% [2 of 23], P = .04). Delirium-related adverse events occurred in 24.3% (18 of 74) of patients with delirium; inadvertent tube or line removals occurred more frequently in the mixed group (P = .006), and sacral skin breakdown was more common in the hypoactive group (P = .002). CONCLUSIONS: Motor subtypes of delirium alert clinicians to differing prognosis and adverse event profiles in postoperative geriatric patients. Hypoactive delirium is the most common motor subtype and is associated with worse prognosis (6-month mortality, 1 in 3 patients). Knowledge of differing adverse event profiles can modify clinicians' management of older patients with postoperative delirium.
