Effects of Organizational Characteristics on Outcomes and Resource Use in Patients With Cancer Admitted to Intensive Care Units.

PURPOSE: To investigate the impact of organizational characteristics and processes of care on hospital mortality and resource use in patients with cancer admitted to intensive care units (ICUs). PATIENTS AND METHODS: We performed a retrospective cohort study of 9,946 patients with cancer (solid, n = 8,956; hematologic, n = 990) admitted to 70 ICUs (51 located in general hospitals and 19 in cancer centers) during 2013. We retrieved patients' clinical and outcome data from an electronic ICU quality registry. We surveyed ICUs regarding structure, organization, staffing patterns, and processes of care. We used mixed multivariable logistic regression analysis to identify characteristics associated with hospital mortality and efficient resource use in the ICU. RESULTS: Median number of patients with cancer per center was 110 (interquartile range, 58 to 154), corresponding to 17.9% of all ICU admissions. ICU and hospital mortality rates were 15.9% and 25.4%, respectively. After adjusting for relevant patient characteristics, presence of clinical pharmacists in the ICU (odds ratio [OR], 0.67; 95% CI, 0.49 to 0.90), number of protocols (OR, 0.92; 95% CI, 0.87 to 0.98), and daily meetings between oncologists and intensivists for care planning (OR, 0.69; 95% CI, 0.52 to 0.91) were associated with lower mortality. Implementation of protocols (OR, 1.52; 95% CI, 1.11 to 2.07) and meetings between oncologists and intensivists (OR, 4.70; 95% CI, 1.15 to 19.22) were also independently associated with more efficient resource use. Neither admission to ICUs in cancer centers compared with general hospitals nor annual case volume had an impact on mortality or resource use. CONCLUSION: Organizational aspects, namely the implementation of protocols and presence of clinical pharmacists in the ICU, and close collaboration between oncologists and ICU teams are targets to improve mortality and resource use in critically ill patients with cancer.

Organizational characteristics, outcomes, and resource use in 78 Brazilian intensive care units: the ORCHESTRA study.

PURPOSE: Detailed information on organization and process of care in intensive care units (ICU) in emerging countries is scarce. Here, we investigated the impact of organizational factors on the outcomes and resource use in a large sample of Brazilian ICUs. METHODS: Retrospective cohort study of 59,693 patients (medical admissions, 67 %) admitted to 78 ICUs during 2013. We retrieved patients' data from an ICU quality registry and surveyed ICUs regarding structure, organization, staffing patterns, and process of care. We used multilevel logistic regression analysis to identify factors associated with hospital mortality. Efficient resource use was assessed by estimating standardized resource use and mortality rates adjusted for the SAPS 3 score. RESULTS: ICUs were mostly medical-surgical (79 %) and located at private hospitals (86 %). Median nurse to bed ratio was 0.20 (IQR, 0.15-0.28) and board-certified intensivists were present 24/7 in 16 (21 %) of ICUs. Multidisciplinary rounds occurred in 67 (86 %) and daily checklists were used in 36 (46 %) ICUs. Most frequent protocols focused on sepsis management and prevention of healthcare-associated infections. Hospital mortality was 14.4 %. In multivariable analysis, the number of protocols was the only organizational characteristic associated with mortality [odds ratio = 0.944 (95 % CI 0.904-0.987)]. The effects of protocols were consistent across subgroups including surgical and medical patients as well as the SAPS 3 tertiles. We also observed a significant trend toward efficient resource use as the number of protocols increased. CONCLUSIONS: In emerging countries such as Brazil, organizational factors, including the implementation of protocols, are potential targets to improve patient outcomes and resource use in ICUs.

Brazilian recommendations of mechanical ventilation 2013. Part 2.

Perspectives on invasive and noninvasive ventilatory support for critically ill patients are evolving, as much evidence indicates that ventilation may have positive effects on patient survival and the quality of the care provided in intensive care units in Brazil. For those reasons, the Brazilian Association of Intensive Care Medicine (Associação de Medicina Intensiva Brasileira - AMIB) and the Brazilian Thoracic Society (Sociedade Brasileira de Pneumologia e Tisiologia - SBPT), represented by the Mechanical Ventilation Committee and the Commission of Intensive Therapy, respectively, decided to review the literature and draft recommendations for mechanical ventilation with the goal of creating a document for bedside guidance as to the best practices on mechanical ventilation available to their members. The document was based on the available evidence regarding 29 subtopics selected as the most relevant for the subject of interest. The project was developed in several stages, during which the selected topics were distributed among experts recommended by both societies with recent publications on the subject of interest and/or significant teaching and research activity in the field of mechanical ventilation in Brazil. The experts were divided into pairs that were charged with performing a thorough review of the international literature on each topic. All the experts met at the Forum on Mechanical Ventilation, which was held at the headquarters of AMIB in São Paulo on August 3 and 4, 2013, to collaboratively draft the final text corresponding to each sub-topic, which was presented to, appraised, discussed and approved in a plenary session that included all 58 participants and aimed to create the final document.

Ventilação mecânica no Brasil: aspectos epidemiológicos / Mechanical ventilation in Brazil: epidemiological aspects

JUSTIFICATIVA E OBJETIVOS: Existem poucos estudos epidemiológicos em ventilação mecânica. O objetivo deste estudo foi demonstrar como a ventilação mecânica vem sendo realizada nas UTI brasileiras. MÉTODO: O estudo foi realizado com prevalência de um dia em 40 UTI, com 390 pacientes internados, sendo 217 em ventilação mecânica. Os resultados medidos foram a caracterização dos pacientes ventilados, sua distribuição pelo Brasil, as causas da ventilação mecânica, os principais modos ventilatórios usados, os parâmetros ventilatórios mais importantes e a fase de desmame da ventilação mecânica. RESULTADOS: As medianas da idade dos pacientes ventilados, do escore APACHE II, e do tempo de ventilação mecânica foram, respectivamente, de 66 anos, 20 pontos e 11 dias. A ventilação mecânica foi determinada pela insuficiência respiratória aguda (IRA) em 71 por cento dos pacientes, o coma em 21,2 por cento, a doença pulmonar obstrutiva crônica em 5,5 por cento e a doença neuromuscular em 2,3 por cento. A ventilação controlada a volume (VCV) (30 por cento), a ventilação com pressão de suporte (PSV) (29,5 por cento) e a ventilação controlada à pressão (PCV) (18 por cento) foram as mais utilizadas, sendo que no desmame predominou a PSV (63,5 por cento). A mediana do volume corrente foi maior nos pacientes em VCV (8 mL/kg). As medianas de pressão inspiratória máxima (30 cmH2O) e de pressão positiva no fim da expiração (PEEP) (8 cmH2O) foram maiores nos pacientes em PCV. CONCLUSÕES: O predomínio de pacientes ventilados nas UTI foi indicado pela sua maior gravidade clínica e pelo maior tempo de internação. A IRA foi a principal indicação de ventilação mecânica. VCV e PSV ventilaram mais pacientes, sendo a PSV na fase de desmame ventilatório.

BACKGROUND AND OBJECTIVES: There are few epidemiological studies in mechanical ventilation, and the aim of the study is to show how this procedure is being used in Brazil. METHODS: A 1-day point prevalence study was performed in 40 ICUs, with 390 patients; 217 of these patients were in mechanical ventilation. The results evaluated were the characteristics of ventilated patients, their distribution in Brazil, the mechanical ventilation's causes, the main ventilatory modes, the more important ventilators settings, and the weaning stage of mechanical ventilation. RESULTS: The median age of the ventilated patients was 66 years old. The median APACHE II was 20, while the median time of mechanical ventilation was 11 days. Acute respiratory failure occurred in 71 percent of the patients, coma in 21.2 percent, acute exacerbation of chronic respiratory failure in 5.5 percent, and the neuromuscular disease in 2.3 percent. The volume-controlled ventilation (VCV) (30 percent), the pressure support ventilation (PSV) (29.5 percent), and the pressure-controlled ventilation (PCV) (18 percent) were the ventilatory modes most used; the PSV had been the main mode in weaning (63.5 percent). The median of tidal volume (8 mL/kg) was higher in VCV. The median of maximal inspiratory pression (30 cmH2O) and the median of positive end-expiration pressure (PEEP) (8 cmH2O) were higher in PCV. CONCLUSIONS: The predominance of ventilated patients in ICUs was marked by clinical severity of them, and a longer hospital stay time; acute respiratory failure was the principal mechanical ventilation cause; VCV and PSV ventilated more patients, with PSV being more used in weaning patients.
