Resumo OBJETIVO Avaliar as notificações e caracterizar os incidentes de quedas dos pacientes adultos internados em unidades clínicas e cirúrgicas de um hospital universitário na região sul do país, no período de 2011 a 2014. MÉTODO Estudo descritivo, transversal e retrospectivo, realizado no período de dezembro de 2016 a dezembro de 2017. A amostra foi de 1112 notificações, abrangendo todos os pacientes internados que foram notificados com ocorrência de quedas no período estudado. Os dados foram analisados por meio de estatística descritiva e analítica. RESULTADOS Foram predominantes na amostra os pacientes do sexo feminino e idosos, onde 69,4% dos incidentes não apresentaram dano. A ocorrência de quedas foi significativamente maior no período noturno. Limitação para deambular e estar desacompanhado foram os fatores mais prevalentes nas condições do paciente antes da queda. CONCLUSÃO Queda é um evento multifatorial que necessita avaliação periódica dos fatores de risco pela equipe para planejar sua prevenção.

Abstract OBJECTIVE To evaluate the occurrences and to characterize the falling incidents of adult patients hospitalized in clinical and surgical units of a university hospital in the southern region of the country, in the period from 2011 to 2014. METHOD Descriptive, cross-sectional and retrospective study, carried out from December 2016 to December 2017. The sample consisted of 1112 reports, covering all hospitalized patients who were notified with falls occurring in the studied period. Data were analyzed using descriptive and analytical statistics. RESULTS Female and elderly patients were predominant in the sample, in which 69.4% of the incidents did not present any damage. The occurrence of falls was significantly higher at night. Limitation to walking and being unaccompanied were the most prevalent factors in the patient's conditions before the fall. CONCLUSION The fall is a multifactorial event that requires periodic evaluation of the risk factors by the team to plan their prevention.

Delirium en ancianos hospitalizados: Seguimiento de 18 meses / Delirium in elderly inpatients: An 18 month follow-up

El objetivo de este trabajo fue describir la prevalencia de síndrome confusional agudo en ancianos hospitalizados, la evolución durante la internación y a los 18 meses. Se evaluó en forma prospectiva a pacientes de 70 años de edad o mayores, internados en el Servicio de Clínica Médica de nuestro hospital, entre septiembre de 2005 y mayo de 2006. Se utilizó una versión validada en español del Confussion Assessment Method para diagnosticar delirium. A los 18 meses se evaluó el estado vital, lugar de residencia, actividades de la vida diaria, dependencia de cuidadores y reinternaciones. Se evaluaron 194 pacientes y 74 fueron excluidos. De los 120 casos incluidos, 52 (43.3%) presentaron delirium. La edad media fue de 82.6 años (DS: 7.4) en el grupo de pacientes con síndrome confusional agudo y de 80.4 años (DS: 5.6) en el grupo de pacientes sin delirium. Al comparar estos dos grupos encontramos diferencias significativas en las características, siendo más frecuentes en el grupo con delirium la residencia previa en un centro de tercer nivel (17.3% vs. 1.5%; p < 0.002), la demencia (40.4% vs. 8.8%; p < 0.001), menor puntaje en la evaluación de las actividades de la vida diaria (5 vs. 6; p < 0.001), más días de internación (7 vs. 5; p = 0.04) y mayor mortalidad intrahospitalaria (21.2% vs. 1.5%; p < 0.001). A los 18 meses de seguimiento después del alta, el desarrollo de delirium durante la internación se asoció a mayor grado de dependencia evidenciado por el peor puntaje en las actividades de la vida diaria (mediana 1/6 vs. 5/6) y a menor sobrevida actuarial 35.3% (CI 95%: 24-49%) a los 569 días y 49% (CI 95%: 32.9-65.4%) a los 644 días (p=0.027).

Delirium usually hardens care during hospitalization and increases morbidity during hospital stay and after discharge. The objective of this study was to describe the prevalence of delirium in elderly inpatients in a Buenos Aires hospital, its morbidity and mortality during hospital stay and the next 18 month follow-up. Patients aged 70 or older admitted to internal medicine unit between September 2005 and May 2006 were enrolled. Delirium was assessed with the Spanish version of Confusion Assessment Method. Demographic data, cause of admition and length of stay, destination after discharge and mortality were registered. A new evaluation was made 18 months after discharge. We evaluated 194 patients and 74 were excluded. Of the 120 included, 52 (43.3%) presented delirium. We found significant differences between patients with and without delirium in previous placement in nursing home (17.3% vs. 1.5%; p < 0.002), dementia (40.4% vs. 8.8%; p < 0.001), median activity of daily living (5 vs. 6; p < 0.001), length-of-stay (7 vs. 5; p = 0.04) and mortality rate (21.2% vs. 1.5%; p < 0.001). Evaluation 18 months later showed differences between patients with and without delirium in median of activity of daily living (1/6 vs. 5/6), patients living in nursing homes (27.5% vs. 7.9%), estimated survival 35.3% (CI 95%: 24-49%) at day 569 and 49% (CI 95%: 32.9-65.4%) at day 644. The difference between survival curves was statistically significant (p = 0.027). Delirium increases morbidity and mortality during hospital stay. Elderly with delirium are at risk of worsening disability and of becoming dependent after discharge and it is a risk factor for higher mortality during the following months after discharge.

Delirium en pacientes de una unidad de cuidados intermedios: estudio prospectivo / Prevalence of delirium in an intermediate care unit

Background: Delirium or acute confusional state is defined as an acute disturbance of consciousness and attention. Its prevalence among hospitalized patients fluctuates between 25 and 60 percent. Aim: To assess the prevalence and features of delirium in an intermediate care unit. Patients and methods: All patients admitted to intermediate care unit during a period of two months were assessed and followed. Delirium was assessed daily during the stay in the unit, using the Inouye Confusion Assessment Method. Delirium was classified as hyperactive if the patient required pharmacological or physical restraining methods. Results: Sixty four patients, 32 female, aged 19 to 90 years old were assessed. Forty one percent had delirium. Of these, delirium started after admission in 46 percent and was hyperactive in 35 percent. Cognitive disturbances were ascertained by the health care team in 69 percent of patients with delirium. Age over 70 years old and a history of dementia were defined as predisposing factors for delirium. Serum albumin was > 3.5 g/dl in 14 of 18 patients with and in 11 of 27 patients without delirium (p=0.04). The most frequent risk factors were systemic infections, metabolic disturbances and intracranial lesions. Physical restraining and neuroleptics were the most commonly used measures to deal with hyperactive patients. Conclusions: The prevalence of delirium found in this study is similar to that reported elsewhere, except for the high proportion of patients whose delirium started after admission
