Predictive Factors for Physiotherapy Session Length at an Adult Intensive Care Unit: A Longitudinal Panel Study.

OBJECTIVE: To identify predictive factors for the length of physiotherapy sessions for adult intensive care unit (ICU) patients. DESIGN: Longitudinal panel study. SETTING: ICU of a secondary-care public teaching hospital, the University Hospital at the University of Sao Paulo, Brazil. PARTICIPANTS: Medical and surgical patients who received physiotherapy (N=181) assessed in 339 physiotherapy sessions. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The study investigator followed physiotherapists during their work shift and timed the physiotherapy session's length with a stopwatch. The association between session length and patient, physiotherapist, and service-related factors was evaluated by a mixed model. RESULTS: Assessed in this study were 339 physiotherapy sessions during 79 periods of observation that involved 181 patients and 19 physiotherapists. Median session length was 29 (interquartile range: 22.6-38.9) minutes; median number of patients assisted per physiotherapist per 6-hour shift was 5 (4-5). Physiotherapist's median age was 35 (26-39) years old, and median ICU experience was 13.0 (0.4-16.0) years. Patients were mostly older adults who were post surgery and had been at the ICU for 5 (2-9) days. Factors associated with physiotherapy session length (min) were the following: performing both motor- and respiratory-related physiotherapy procedures during the session (ß=6.5; 95% confidence interval [CI], 3.8-9.2), altered chest x-ray (ß=2.8; 95% CI, 0.3-5.3), ICU mobility scale (IMS) (ß=1.2; 95% CI, 0.4-2.0), contraindication to any level of out-of-bed mobilization (ß=-6.9; 95% CI, -10.5 to -3.3), afternoon shift (ß=-4.0; 95% CI, -6.7 to -1.4), and Barthel index (ß=-0.2; 95% CI, -0.3 to -0.1). CONCLUSIONS: The factors associated with longer session lengths were performing both motor- and respiratory-related physiotherapy procedures during the session, altered chest x-ray, and the IMS. Contraindication to any level of out-of-bed mobilization and sessions performed during the afternoon shift (vs the morning shift) were associated with shorter session lengths.

Functional Recovery Groups in Critically Ill COVID-19 Patients and Their Associated Factors: From ICU to Hospital Discharge.

OBJECTIVES: To analyze functional recovery groups of critically ill COVID-19 survivors during their hospital stay and to identify the associated factors. DESIGN: Prospective observational multicenter study. SETTING: Demographic, clinical, and therapeutic variables were collected, and physical and functional status were evaluated. The Barthel index was evaluated at three time points: 15 days before hospitalization, at ICU discharge, and at hospital discharge from the ward. PATIENTS: Patients with functional independence before COVID-19 diagnosis were recruited from four hospitals and followed up until hospital discharge. MEASUREMENTS AND MAIN RESULTS: Three groups of functional recovery were described for 328 patients: functional independence ( n = 144; 44%), which included patients who preserved their functional status during hospitalization; recovered functionality ( n = 109; 33.2%), which included patients who showed dependence at ICU discharge but recovered their independence by hospital discharge; and functional dependency ( n = 75; 22.8%), which included patients who were dependent at ICU discharge and had not recovered their functional status at hospital discharge. The factors associated with becoming functionally dependent at ICU discharge were time to out-of-bed patient mobilization (odds ratio [OR], 1.20; 95% CI, 1.11-1.29), age (OR, 1.02; 95% CI, 1.01-1.04), hyperglycemia (OR, 2.52; 95% CI, 1.56-4.07), and Simplified Acute Physiology Score (OR, 1.022; 95% CI, 1.01-1.04). Recovery to baseline independence during ward stays was associated with ICU length of stay (OR, 0.97; 95% CI, 0.94-0.99) and muscle strength (Medical Research Council test) at ICU discharge (OR, 1.13; 95% CI, 1.08-1.18). CONCLUSIONS: Age, hyperglycemia, and time for patient mobilization out of bed were independent factors associated with becoming physically dependent after their ICU stay. Recovery of physical function at hospital discharge was associated with muscle strength at ICU discharge and length of ICU stay.

Impact of a Progressive Mobility Program on the Functional Status, Respiratory, and Muscular Systems of ICU Patients: A Randomized and Controlled Trial.

OBJECTIVES: The aim was to investigate whether patients who participated in a mobility program in the ICU performed better on functional status, muscle, mobility, and respiratory assessments upon discharge than patients who received conventional physiotherapy. DESIGN: Randomized controlled trial. SETTING: Blind evaluation. PATIENTS: Adults with previous functional independence and without contraindications for mobilization were eligible. INTERVENTIONS: The intervention group participated in an early and progressive mobility program with five levels of activity. The control group underwent the conventional treatment without a preestablished routine. We evaluated functional status, level of activity, respiratory status, muscle strength, and mobility at ICU discharge. MEASUREMENTS AND MAIN RESULTS: We analyzed 49 patients in the control group and 50 patients in the intervention group. Our data showed patients with better functional status and more functionally independent patients in the intervention group compared with those in the control group (96% vs 44%; p < 0.001). The results of the sit-to-stand and 2-minute walk tests, as well as the results of the maximum voluntary ventilation tests, also varied between the groups. The intervention group had shorter ICU stays than the control group. Higher Barthel index scores were associated with the amount of activity and participation in the protocol. The benefits to functional status remained during follow-up. CONCLUSIONS: Patients who participated in an ICU mobility program had better functional status at discharge from the ICU. The other benefits of the program included better performance in the mobility tests and improved maximum voluntary ventilation performance.

Assessing functional status after intensive care unit stay: the Barthel Index and the Katz Index.

OBJECTIVE: To assess the functional status of post-ICU patients using the Barthel Index (BI) and the Katz Index (KI) and to assess which is more suitable for this population. DESIGN: Retrospective longitudinal study. SETTING: Public tertiary hospital in São Paulo (Brazil). PARTICIPANTS: Patients aged ≥18 years old, admitted to ICU, who were treated with mechanical ventilation (MV) ≥ 24 h and were discharged to ward. EXCLUSION CRITERIA: Inability to answer the BI and the KI; limiting neurological or orthopaedic conditions; ICU stay ≥90 days. Patients transferred to or from other hospitals or who died in the wards were not analysed. INTERVENTION: BI and KI were scored pre-ICU and post-ICU and the variation was calculated. MAIN OUTCOME MEASURES: BI and KI scores were compared using analysis based on item response theory (IRT), using degree of difficulty and discriminating items as parameters. RESULTS: Median age was 52 years old, median APACHE II score was 15. Median ICU stay was 11 days and median MV duration was 4 days. BI variation was 44% and KI variation was 55%. In IRT analysis, BI considered a larger number of items with different levels of difficulty. CONCLUSION: Both the BI and the KI revealed significant deterioration of functional status after ICU discharge. The IRT analysis suggested that the Barthel Index might be a better scale than the Katz Index for the assessment of functional status of patients discharged from ICU, since it presented better discrimination of the ability to carry out the tasks.

Recovery of functional capacity in severe trauma victims at one year after injury: association with trauma-related and hospital stay aspects.

[Purpose] The aim of this study was to investigate the functional capacity of trauma survivors one year after hospital discharge and to identify associations with trauma- and hospital stay-related aspects in a developing country. [Subjects and Methods] This study included severe trauma patients (Injury Severity Score ≥16; ≥18 years old) who were admitted to an intensive care unit in Sao Paulo, Brazil. Hospital stay data were collected from the patients' records. Functional capacity was assessed using the Glasgow Outcome Scale and Lawton Instrumental Activities of Daily Living Scale one year after hospital discharge. Patients were asked if they had returned to work/school. [Results] Forty-nine patients completed follow-up. According to the Glasgow Outcome Scale data, most patients had moderate or mild/no dysfunction. The Lawton Instrumental Activities of Daily Living Scale showed that 60-70% of the subjects performed most activities independently. Multiple linear regression of the Glasgow score, Acute Physiology and Chronic Health Disease Classification System II score, length of mechanical ventilation, and hospital length of stay revealed an association between the Lawton Instrumental Activities of Daily Living Scale and hospital length of stay. Overall, 32.6% of the subjects had returned to work/school. [Conclusion] Most severe trauma patients experienced functional recovery, although only one-third had returned to work/school one year after hospital discharge. Hospital length of stay was identified as a significant predictor of functional recovery.

Quality of life of critically ill patients in a developing country: a prospective longitudinal study.

[Purpose] To evaluate the quality of life of critical illness survivors in a developing country over the time after hospital discharge and to assess the influence of clinical variables on quality of life. [Subjects and Methods] A prospective longitudinal study was conducted in a large, tertiary, public hospital in Sao Paulo, Brazil. We included patients ≥18 years old, hospitalized in the intensive care unit with ≥24 hours of invasive mechanical ventilation. Quality of life was assessed using the Medical Outcomes Study 36-Item Short Form Health Survey, which was applied by telephone interview at the first, third and sixth months after hospital discharge. [Results] 75 patients were included in the study. Quality of life improved progressively after hospital discharge; role-physical was the most compromised domain. The physical component was influenced by the age. Quality of life was not influenced by Apache II categorization, length of invasive mechanical ventilation, intensive care unit stay or hospital stay. [Conclusion] Survivors of critical illness in a developing country present poor quality of life, which improves over time. Age influenced the physical component of quality of life.

Risk Factors for the Impairment of Ambulation in Older People Hospitalized with COVID-19: A Retrospective Cohort Study.

(1) Background: Some older people hospitalized with COVID-19 have experienced reduced ambulation capacity. However, the prevalence of the impairment of ambulation capacity still needs to be established. Objective: To estimate the prevalence of, and identify the risk factors associated with, the impairment of ambulation capacity at the point of hospital discharge for older people with COVID-19. (2) Methods: A retrospective cohort study. Included are those with an age > 60 years, of either sex, hospitalized due to COVID-19. Clinical data was collected from patients' medical records. Ambulation capacity prior to COVID-19 infection was assessed through the patients' reports from their relatives. Multiple logistic regressions were performed to identify the risk factors associated with the impairment of ambulation at hospital discharge. (3) Results: Data for 429 older people hospitalized with COVID-19 were randomly collected from the medical records. Among the 56.4% who were discharged, 57.9% had reduced ambulation capacity. Factors associated with reduced ambulation capacity at discharge were a hospital stay longer than 20 days (Odds Ratio (OR): 3.5) and dependent ambulation capacity prior to COVID-19 (Odds Ratio (OR): 11.3). (4) Conclusion: More than half of the older people who survived following hospitalization due to COVID-19 had reduced ambulation capacity at hospital discharge. Impaired ambulation prior to the infection and a longer hospital stay were risks factors for reduced ambulation capacity.

Functional impact on adults and older people after hospitalization by Covid-19.

BACKGROUND AND OBJECTIVES: Hospitalization by Covid-19 can cause persistent functional consequences after hospital discharge due to direct and indirect effects of SARS-COV-2 in several organs and systems of the body added to post-intensive care syndrome and prolonged bed rest. These impacts can lead to dependency in activities of daily living, mainly in older people due to aging process and functional decline. This study aimed to compare the effects of hospitalization by Covid-19 on functional capacity of adults and older people and to identify its associated factors. METHODS: Cross-sectional observational study of 159 survivors of hospitalization by Covid-19 after 1 month from discharge at Hospital das Clínicas of the University of São Paulo, divided into groups: adults (aged < 60 years) and older people (aged ≥ 60 years). Those who did not accept to participate, without availability or without ability to understand the questionnaires were excluded. Functional capacity was assessed by the Barthel Index and patients were classified according to their scores. Data analysis was performed in JASP Statistics program and the sample was compared between the age groups. Wilcoxon test was applied to compare before and after periods, Mann-Whitney test was used for between groups comparison. We adopted alpha = 0.05. RESULTS: The total Barthel Index median score was lower 1 month after hospital discharge than in the pre-Covid-19 period. Older people had worse functional status than adults before and also showed greater impairment after hospital discharge. Both groups showed lower Barthel Index classification than before, and older people presented more functional dependence than adults in both periods. Age, sarcopenia and frailty were associated factors. DISCUSSION: Hospitalization by Covid-19 impacts functional capacity after 1 month from discharge, especially in older people. Age, sarcopenia and frailty are associated factors. These results suggest need for care and rehabilitation of Covid-19 survivors.

Factors associated with functional decline in an intensive care unit: a prospective study on the level of physical activity and clinical factors. / Fatores associados com o declínio funcional em uma unidade de terapia intensiva: estudo prospectivo sobre o nível de atividade física e os fatores clínicos.

OBJECTIVE: To identify the factors associated with functional status decline in intensive care unit patients. METHODS: In this prospective study, patients in an intensive care unit aged 18 years or older without neurological disease or contraindications to mobilization were included. The exclusion criteria were patients who spent fewer than 4 days in the intensive care unit or died during the study period. Accelerometry was used to assess the physical activity level of patients. We recorded age, SAPS 3, days on mechanical ventilation, drugs used, comorbidities, and functional status after intensive care unit discharge. After intensive care unit discharge, the patients were assigned to a dependent group or an independent group according to their Barthel index. Logistic regression and the odds ratio were used in the analyses. RESULTS: Sixty-three out of 112 included patients were assigned to the dependent group. The median Charlson comorbidity index was 3 (2 - 4). The mean SAPS 3 score was 53 ± 11. The patients spent 94 ± 4% of the time spent in inactivity and 4.8 ± 3.7% in light activities. The odds ratio showed that age (OR = 1.08; 95%CI 1.04 - 1.13) and time spent in inactivity (OR = 1.38; 95%CI 1.14 - 1.67) were factors associated with functional status decline. Time spent in light activity was associated with a better functional status (OR = 0.73; 95%CI 0.60 - 0.89). CONCLUSIONS: Age and time spent in inactivity during intensive care unit stay are associated with functional status decline. On the other hand, performing light activities seems to preserve the functional status of patients.

OBJETIVO: Identificar os fatores associados com o declínio do estado funcional em pacientes na unidade de terapia intensiva. MÉTODOS: Foram incluídos neste estudo prospectivo pacientes com idade de 18 anos ou mais, sem doença neurológica ou contraindicações para mobilização, internados em uma unidade de terapia intensiva. Os critérios para exclusão foram pacientes com permanência na unidade de terapia intensiva inferior a 4 dias, ou com óbito durante o período do estudo. A avaliação do nível de atividade física dos pacientes foi realizada com acelerometria. Registraram-se idade, escore segundo o SAPS 3, dias de ventilação mecânica, fármacos utilizados, comorbidades e estado funcional por ocasião da alta da unidade de terapia intensiva. Segundo seu estado funcional na alta da unidade de terapia intensiva, os pacientes foram designados para os grupos "dependentes" ou "independentes", segundo seu índice na escala de Barthel. As análises foram realizadas com regressão logística e cálculo da razão de chance. RESULTADOS: Dos 112 pacientes incluídos, 63 foram atribuídos ao grupo "dependentes". O índice de comorbidade de Charlson mediano foi de 3 (2 - 4). O SAPS 3 médio foi de 53 ± 11. Os pacientes permaneceram 94 ± 4% do tempo na unidade de terapia intensiva em condições de inatividade e 4,8 ± 3,7% em atividades leves. As análises de razão de chance mostraram que idade (RC = 1,08; IC95% 1,04 - 1,13) e tempo de inatividade (RC =1,38; IC95% 1,14 - 1,67) foram fatores associados ao declínio funcional. O tempo em atividades leves se associou com melhor estado funcional (RC = 0,73; IC95% 0,60 - 0,89). CONCLUSÃO: Idade e tempo em inatividade durante a internação na unidade de terapia intensiva se associaram com declínio do estado funcional. Por outro lado, a realização de atividades leves parece preservar a condição funcional dos pacientes.

Ambulation capacity, age, immunosuppression, and mechanical ventilation are risk factors of in-hospital death in severe COVID-19: a cohort study.

IMPORTANCE: Despite ambulation capacity being associated with a decreased level of physical activity and survival may be influenced by the functional capacity, studies have not addressed the association between ambulation capacity and death in patients hospitalized by COVID-19. OBJECTIVE: To verify the functional, clinical, and sociodemographic risk factors associated with in-hospital death in individuals with severe COVID-19. METHODS: It is a cohort retrospective study performed at a large tertiary hospital. Patients 18 years of age or more, of both sexes, hospitalized due to severe COVID-19 were included. Cases with dubious medical records and/or missing essential data were excluded. Patients were classified according to their ambulation capacity before the COVID-19 infection. Information regarding sociodemographic characteristics, in-hospital death, total hospital stays, Intensive Care Unit (ICU) stays, and the necessity of Mechanical Ventilation (MV) were collected from medical records and registered in a RedCap database. Multiple logistic regression analysis was used to identify possible factors associated with the in-hospital death rate. RESULTS: Data from 1110 participants were included in the statistical analysis. The median age of the patients was 57 (46‒66) years, 58.42% (n = 590) were male, and 61.73% (n = 602) were brown or black. The case fatality rate during hospitalization was 36.0% (n = 363). In-hospital death was associated with ambulation capacity; dependent ambulators (OR = 2.3; CI 95% = 1.2-4.4) and non-functional ambulation (OR = 1.9; CI 95% = 1.1-3.3), age [older adults (OR = 3.0; CI 95% = 1.9‒4.), ICU stays (OR = 1.4; CI 95% = 1.2‒1.4), immunosuppression (OR = 5.5 CI 95% = 2.3‒13.5) and mechanical ventilation (OR = 27.5; CI 95% = 12.0-62.9). CONCLUSION AND RELEVANCE: Decreased ambulation capacity, age, length of ICU stay, immunosuppression, and mechanical ventilation was associated with a high risk of in-hospital death due to COVID-19.

Association of the mobility level of critically ill adult patients with the success of extubation: protocol for a cohort study.

INTRODUCTION: Several factors contribute to the reduction of the mobility in ICU), such as the use of sedatives, severity, invasive devices, acute clinical instability, lack of resources, the culture of immobility, architectural barriers and the own weakness developed in the ICU. The need for ventilatory support is common in most of patients, and weaning from mechanical ventilation (MV) is an arduous process that requires the commitment of the entire team. Instruments that objectively assess the mobility of patients admitted to the ICU can be useful to identify the existence or not of an association between mobility and prognosis. OBJECTIVE: To estimate the association between the level of mobility and successful extubation. METHODS AND ANALYSIS: Prospective cohort study with the beginning of follow-up when the patient completes 24 hours of invasive MV in the ICU and ends on the date the patient's hospital discharge. Adult patients (≥18 years old) admitted to the ICU will be included in the first invasive MV event in this hospitalisation. Patients should be independently able to mobilise before current hospital admission. Predictor variables will be collected (age, sex, body mass index, Simplified Acute Physiological Score III (SAPS III), ICU admission type: clinic, elective or emergency surgery postoperative, Charlson Index, number of physiotherapists per patient in each ICU, use of sedation, vasoactive drugs and neuromuscular blocker, ICU mobility scale, time of invasive MV, ICU admission and hospital admission, and outcome. The primary outcome is the result of extubation (success or failure). ETHICS AND DISSEMINATION: This study was approved by the Ethics Committee, certificate number 92878218.1.0000.5505. The protocol was registered on the Registro Brasileiro de Ensaios Clínicos (ReBEC) (registration number RBR-8k4f68). The results will be published in specialised journals and disseminated to the medical society and the general public.

24/7 Physical Therapy Intervention With Adult Patients in a Chilean Intensive Care Unit: A Cost-Benefit Analysis in a Developing Country.

OBJECTIVES: Physiotherapy in an adult intensive care unit (ICU) affects health outcome. To justify the investment in ICU physical therapy, the cost savings associated with its benefits need to be established. The main objective of this study is to evaluate the potential cost savings of implementing 24-hour, 7-days-per-week physiotherapist (24/7-PT) in a Chilean public high-complex specialized ICU. METHODS: Using clinical data from a literature review and a micro-costing technique, we conducted a cost-benefit analysis in the National Institute of Thorax in Chile. Our example scenario involves 697 theoretical admissions of adult patients with cardiovascular or respiratory diseases, and the costs and benefits by reduction of length of stay in ICU, days of mechanical ventilation, and days with respiratory infections during the first year and 5 years of admissions. A sensitivity analysis was considered according to the variability in total costs, production income, and clinical benefits. RESULTS: Net cost savings generated in our example scenario demonstrate that the implementation of 24/7-PT produces a minimum saving for the institution of $16 242 during the first year and $69 351 over a 5-year interval considering individual income production. Out of the 30 scenarios included in the sensitivity analyses, 26 (87%) demonstrated net savings. CONCLUSIONS: A financial model, based on literature review and actual cost data, projects that 24/7-PT intervention is a cost-benefit alternative in adult ICU patients with cardiovascular or respiratory diseases in Chile. It is necessary a scenario of at least 3 sessions per day with insurance payment for individual treatments to support the long-term implementation of a 24/7-PT program.

Rehabilitation through virtual reality: physical activity of patients admitted to the intensive care unit. / Reabilitação com uso de realidade virtual: atividade física para pacientes admitidos na unidade de terapia intensiva.

OBJECTIVE: To evaluate the level of activity that Nintendo WiiTM can elicit in intensive care unit patients and its associated safety and patient satisfaction. METHODS: Experimental, single-center study performed at a tertiary care hospital. Patients ≥ 18 years old who were admitted to the intensive care unit, participated in videogames as part of their physical therapy sessions and did not have mobility restrictions were included. Th exclusion criteria were the inability to comprehend instructions and the inability to follow simple commands. We included n = 60 patients and performed 100 sessions. We used the Nintendo WiiTM gaming system in the sessions. An accelerometer measured the level of physical activity of patients while they played videogames. We evaluated the level of activity, the modified Borg scale scores, the adverse events and the responses to a questionnaire on satisfaction with the activity. RESULTS: One hundred physical therapy sessions were analyzed. When the patients played the videogame, they reached a light level of activity for 59% of the session duration and a moderate level of activity for 38% of the session duration. No adverse events occurred. A total of 86% of the patients reported that they would like to play the videogame in their future physical therapy sessions. CONCLUSION: Virtual rehabilitation elicited light to moderate levels of activity in intensive care unit patients. This therapy is a safe tool and is likely to be chosen by the patient during physical therapy.

OBJETIVO: Avaliar o nível de atividade que o uso do videogame Nintendo WiiTM pode provocar em pacientes na unidade de terapia intensiva, além dos níveis de segurança do método e da satisfação do paciente. MÉTODOS: Ensaio experimental em centro único conduzido em um hospital terciário. Incluíram-se pacientes com idade igual ou superior a 18 anos admitidos à unidade de terapia intensiva, sem restrições à mobilidade, que utilizaram videogames como parte de suas sessões de fisioterapia. Os critérios de exclusão foram incapacidade para compreender as instruções e para atender a comandos simples. Incluímos 60 pacientes e conduzimos 100 sessões, nas quais utilizamos o equipamento de videogame Nintendo WiiTM. Utilizou-se um acelerômetro para avaliar os níveis de atividade física dos pacientes enquanto interagiam com o videogame. Avaliamos os níveis de atividade, escores segundo a escala modificada de Borg, ocorrência de eventos adversos e respostas a questionários relativos à satisfação com a atividade. RESULTADOS: Analisamos um total de 100 sessões de fisioterapia. Enquanto jogavam videogame, os pacientes atingiram grau leve de atividade em 59% da duração das sessões, e nível moderado de atividade em 38% da duração das sessões. Não ocorreu qualquer evento adverso. Dentre os pacientes, 86% relataram que gostariam de jogar videogame em suas próximas sessões de fisioterapia. CONCLUSÃO: O uso de equipamento virtual para reabilitação proporcionou níveis leves a moderados de atividade em pacientes na unidade de terapia intensiva. Esta modalidade de fisioterapia utiliza ferramenta simples com probabilidade de ser escolhida pelos pacientes para as próximas sessões de fisioterapia.

Decline in functional status after intensive care unit discharge is associated with ICU readmission: a prospective cohort study.

OBJECTIVES: To compare the functional status at intensive care unit (ICU) discharge of patients who were later readmitted to the ICU and patients discharged home and to verify whether a decline in functional status is associated with ICU readmission. DESIGN: Prospective cohort study. SETTING: ICU at a tertiary teaching hospital. PARTICIPANTS: Patients admitted to the ICU, ≥18 years old, submitted to invasive mechanical ventilation (IMV), and discharged to the ward. INTERVENTIONS: Functional assessment at ICU discharge. Discharge Group (DG) (patients discharged home) and Readmission Group (RG) (patients who returned to the ICU) were compared with Mann-Whitney and Chi-square or Exact Fisher tests. Multiple logistic regression verified association. MAIN OUTCOME MEASURES: Barthel Index, key pinch strength, clinical and demographic data. RESULTS: Patients in the readmission group presented lower Barthel Index [Median 40 (IQR 20-75) vs 60 (33-83), P=0.033], greater relative variation (pre and post ICU) of the Barthel Index (P=0.04), lower key pinch strength [3.4 (1.8-4.5) vs 4.5 (2.7-6.8)kg·f, P=0.006] and higher APACHE II [18 (12-22) vs 15 (11-20), P=0.027]. Multiple regression found that the relative variation of the Barthel Index was independently associated with ICU readmission (P<0.001), as well as higher APACHE II (P=0.020), shorter IMV duration (P<0.001) and ICU admission without clear diagnosis (P=0.020). The Hosmer-Lemeshow test indicated good adjustment of the model (P=0.99). CONCLUSION: Readmitted patients presented poorer functional status and lower pinch strength. Relative variation of the Barthel Index was associated with ICU readmission despite other factors, as was higher APACHE II, shorter IMV duration and admission without clear diagnosis. TRIAL REGISTRATION NUMBER: Not applicable.

Characteristics of physiotherapy staffing levels and caseload: a cross-sectional survey of Chilean adult Intensive Care Units.

INTRODUCTION: The European Society of Intensive Care Medicine recommends the presence of a specialist physiotherapist, available every five beds, seven days a week in the high complexity Intensive Care Unit. However, in Chile the adherence of adult Intensive Care Units to this recommendation is unknown. OBJECTIVE: To describe the organizational characteristics and the physiotherapist availability in adult Intensive Care Units in Chile, and according to the adherence to international recommendations, inform health decision-makers. METHODS: Observational study based on a telephone survey. All adult Intensive Care Units institutions of high complexity, private hospitals and teaching health centers in Chile were eligible (n = 74). The primary outcome measures were the proportion of institutions with physiotherapist availability 24 hours a day and seven days a week (24/7 physiotherapist), a maximum caseload per physiotherapist of five patients and the presence of a specialist physiotherapist. RESULTS: Response rate was 86.5%, with 59% of responding units being public and 83% offering level III care. 70% of the adult Intensive Care Units in Chile have 24/7 physiotherapist (87% of the public and 46% of the private sector). 41% of the centers had a maximum caseload per physiotherapist of five patients during the day on weekdays. This number decreased on weekends and during night shifts. 23% of the Intensive Care Units had a specialist physiotherapist, being more common in the private sector (31%). CONCLUSIONS: In Chilean adult ICU, 24/7 physiotherapist availability is high, the prevalence of physiotherapists with specialist training is low. Future efforts should focus on promoting the uptake of specialist training.

INTRODUCCIÓN: La Sociedad Europea de Medicina de Cuidados Intensivos recomienda la presencia de un Kinesiólogo con formación especializada, disponible cada cinco camas de alta complejidad, los 7 días de la semana en la Unidad de Cuidados Intensivos (UCI). En Chile se desconoce la adherencia de las UCI adulto a esta recomendación. OBJETIVO: Describir las características administrativas y de cobertura kinésica en las UCI adulto chilenas, y de acuerdo con la adherencia a las recomendaciones internacionales, informar a los tomadores de decisión en salud. MÉTODOS: Estudio observacional transversal, basado en encuesta telefónica. Se incluyeron las UCI adultos de establecimientos de mayor complejidad, clínicas privadas y centros asociados a universidades (n = 74). La proporción de instituciones con disponibilidad de kinesiólogos las 24 horas del día, los siete días de la semana (kinesiólogo 24/7), con un número máximo de cinco pacientes por kinesiólogo y presencia de un kinesiólogo especialista fueron reportados. RESULTADOS: La tasa de respuesta fue del 86,5% (n = 64), principalmente públicas (59%) y de nivel III (83%). El 70% (n = 45) de las UCI adulto chilenas cuentan con kinesiólogo 24/7; correspondiendo el 87% al sector público y el 46% al privado. El 41% de los centros posee un máximo de 5 pacientes por kinesiólogo en día hábil diurno, disminuyendo en fines de semana y horarios nocturnos. Un 23% de las UCIs cuenta con kinesiólogo especialista en intensivo, siendo mayor en el sector privado (31%). CONCLUSIONES: En UCI adulto chilenas, la disponibilidad de kinesiólogos 24/7 es alta, y la prevalencia de especialistas es baja. Estrategias de creación de programas de formación de especialidad podrían contribuir a disminuir la brecha de especialistas.

Progressive mobility program and technology to increase the level of physical activity and its benefits in respiratory, muscular system, and functionality of ICU patients: study protocol for a randomized controlled trial.

BACKGROUND: Enhanced mobility in the Intensive Care Unit (ICU) could minimize the negative effects of critical illness, such as declines in cognitive, muscular, respiratory, and functional capacity. We aim to compare the functional status at ICU discharge of patients who underwent a progressive mobilization protocol versus patients who received conventional physiotherapy. We also examine the level of physical activity in the ICU, the degree of pulmonary and muscle function, and the length of stay to analyze correlations between these variables. METHODS: This is a protocol for a randomized controlled trial with blind evaluation. Ninety-six ICU patients will be recruited from a single center and randomly assigned to a control group or an intervention group. To determine the level of protocol activity the patient will receive, the patients' ability to participate actively and their muscle strength will be considered. The protocol consists of five phases, ranging from passive therapies to walking and climbing stairs. The primary outcome will be the functional status at ICU discharge, measured with the Barthel Index and the ICU Mobility Scale (IMS). Measured secondary outcomes will include the level of physical activity, maximal inspiratory and expiratory pressures, forced expiratory volume in 1 second, maximum voluntary ventilation, handgrip strength, surface electromyography of the lower limb muscles, and results of the Timed Up and Go and 2-Minute Walk tests. Evaluations will be made within 2 days of ICU discharge except for the level of activity, which will be evaluated daily. Physiological variables and activity level will be analyzed by chi-square and t tests, according to the intention-to-treat paradigm. DISCUSSION: Mobility and exercise in the ICU should be undertaken with intensity, quantity, duration, and frequency adjusted according to the patients' status. The results of this study may contribute to new knowledge of early mobility in the ICU, activity level, and varying benefits in critical patients, directing new approaches to physiotherapeutic interventions in these patients. TRIAL REGISTRATION: Recruitment will begin in February 2017, and the expected completion date is August 2018. Patients are already being recruited. ClinicalTrials.gov, ID: NCT02889146 . Registered on 3 March 2016.

Relationship between availability of physiotherapy services and ICU costs.

OBJECTIVE: To determine whether 24-h availability of physiotherapy services decreases ICU costs in comparison with the standard 12 h/day availability among patients admitted to the ICU for the first time. METHODS: This was an observational prevalence study involving 815 patients ≥ 18 years of age who had been on invasive mechanical ventilation (IMV) for ≥ 24 h and were discharged from an ICU to a ward at a tertiary teaching hospital in Brazil. The patients were divided into two groups according to h/day availability of physiotherapy services in the ICU: 24 h (PT-24; n = 332); and 12 h (PT-12; n = 483). The data collected included the reasons for hospital and ICU admissions; Acute Physiology and Chronic Health Evaluation II (APACHE II) score; IMV duration, ICU length of stay (ICU-LOS); and Omega score. RESULTS: The severity of illness was similar in both groups. Round-the-clock availability of physiotherapy services was associated with shorter IMV durations and ICU-LOS, as well as with lower total, medical, and staff costs, in comparison with the standard 12 h/day availability. CONCLUSIONS: In the population studied, total costs and staff costs were lower in the PT-24 group than in the PT-12 group. The h/day availability of physiotherapy services was found to be a significant predictor of ICU costs.

The effects of recruitment maneuver during noninvasive ventilation after coronary bypass grafting: A randomized trial.

OBJECTIVE: Pulmonary impairment is a common complication after coronary artery bypass graft procedure and may be prevented or treated by noninvasive ventilation. Recruitment maneuvers include sustained airway pressure with high levels of positive end-expiratory pressure in patients with hypoxemia, favoring homogeneous pulmonary ventilation and oxygenation. This study aimed to evaluate whether noninvasive ventilation with recruitment maneuver could safely improve oxygenation in patients with atelectasis and hypoxemia who underwent a coronary artery bypass grafting procedure. METHODS: Thirty-four patients admitted to our intensive care unit undergoing mechanical ventilation after surgery, with ratio of arterial oxygen partial pressure to fraction of inspired oxygen < 300 and radiologic atelectasis score ≥2, were included. The control group consisted of 16 randomized patients and the recruitment group consisted of 18 patients. After extubation, noninvasive ventilation was applied for 30 minutes 3 times a day with positive end-expiratory pressure of 8 cm H2O. The recruitment group received recruitment maneuver with positive end-expiratory pressure of 15 cm H2O and 20 cm H2O for 2 minutes each during noninvasive ventilation. We analyzed the arterial oxygen partial pressure in room air, radiologic atelectasis score, hemodynamic stability, and adverse events from extubation until discharge. RESULTS: Arterial oxygen partial pressure increased 12.6% ± 6.8% in the control group and 23.3% ± 8.5% in the recruitment group (P < .001). The radiologic atelectasis score was completely improved for 94.4% of the recruitment group with no adverse events, whereas 87.5% of the control group presented some atelectasis (P < .001). CONCLUSIONS: Noninvasive ventilation with recruitment maneuvers is safe, improves oxygenation, and reduces atelectasis in patients undergoing coronary artery bypass.

Effect of hemodialysis on intra-abdominal pressure.

OBJECTIVE: To study the effect of hemodialysis on intra-abdominal pressure. METHODS: Five patients admitted between July and November of 2003 were evaluated in the intensive care unit. Intra-abdominal pressure was measured before and after hemodialysis, maintaining the ventilatory parameters except for PEEP (positive-end expiratory pressure). RESULTS: Intra-abdominal pressure was significantly reduced by hemodialysis in all the 5 patients. CONCLUSION: Hemodialysis significantly reduced intra-abdominal pressure in the 5 patients, an effect which could have influence over other organic systems. This reduction is related to the weight variation before and after hemodialysis, as well as to the loss of volume caused by this procedure.
