ASSESSMENT OF A NEW SMOKING CESSATION PROGRAM AT THAMMASAT UNIVERSITY HOSPITAL, PATHUM THANI, THAILAND.

The Smoking Cessation Clinic (SCC) at Thammasat University Hospital had only 27 patients from October 2013 to September 2014 and a quit rate of only 3.7%. A new smoking cessation program was implemented at the end of 2014 to improve success rates. This new program is an interdisciplinary program that includes several health care specialists. The study aimed to examine the characteristics of the smokers and the outcomes after implementing the new program with an interdisciplinary approach at the SCC in order to gain data to improve the efficacy of the SCC. This prospective descriptive study was conducted by the SCC from December 2014 to December 2015. During the study period 111 patients attended the SCC under the new program and all were included in the survey; 100 (90.1%) were men. The mean (±SD) age of these patients was 56.5±13.5 years. The mean (±SD) age of onset of smoking was 18.5±5.5 years. Smoking cessation in the program was checked by measuring the exhaled carbon monoxide levels at 6 months after reporting smoking cessation. A level less than 10 parts per million was considered not to be a smoker. Of the 111 patients, 14 (12.6%) had reported smoking cessation and had an exhaled carbon monoxide level less than 10 parts per million. The new smoking cessation program was attended by more patients and had a higher success rate than the previous smoking cessation program, although the smoking cessation success rate was still low. Further studies are needed to determine which factors improved cessation rates and to determine other factors associated with successful smoking cessation in the study population.

Posttraumatic stress disorder in critical illness survivors: a metaanalysis.

OBJECTIVE: To conduct a systematic review and metaanalysis of the prevalence, risk factors, and prevention/treatment strategies for posttraumatic stress disorder symptoms in critical illness survivors. DATA SOURCES: PubMed, Embase, CINAHL, PsycINFO, and Cochrane Library from inception through March 5, 2014. STUDY SELECTION: Eligible studies met the following criteria: 1) adult general/nonspecialty ICU, 2) validated posttraumatic stress disorder instrument greater than or equal to 1 month post-ICU, and 3) sample size greater than or equal to 10 patients. DATA EXTRACTION: Duplicate independent review and data abstraction from all eligible titles/abstracts/full-text articles. DATA SYNTHESIS: The search identified 2,817 titles/abstracts, with 40 eligible articles on 36 unique cohorts (n = 4,260 patients). The Impact of Event Scale was the most common posttraumatic stress disorder instrument. Between 1 and 6 months post-ICU (six studies; n = 456), the pooled mean (95% CI) Impact of Event Scale score was 20 (17-24), and the pooled prevalences of clinically important posttraumatic stress disorder symptoms (95% CI) were 25% (18-34%) and 44% (36-52%) using Impact of Event Scale thresholds greater than or equal to 35 and greater than or equal to 20, respectively. Between 7 and 12 months post-ICU (five studies; n = 698), the pooled mean Impact of Event Scale score was 17 (9-24), and pooled prevalences of posttraumatic stress disorder symptoms were 17% (10-26%) and 34% (22-50%), respectively. ICU risk factors for posttraumatic stress disorder symptoms included benzodiazepine administration and post-ICU memories of frightening ICU experiences. Posttraumatic stress disorder symptoms were associated with worse quality of life. In European-based studies: 1) an ICU diary was associated with a significant reduction in posttraumatic stress disorder symptoms, 2) a self-help rehabilitation manual was associated with significant posttraumatic stress disorder symptom reduction at 2 months, but not 6 months; and 3) a nurse-led ICU follow-up clinic did not reduce posttraumatic stress disorder symptoms. CONCLUSIONS: Clinically important posttraumatic stress disorder symptoms occurred in one fifth of critical illness survivors at 1-year follow-up, with higher prevalence in those who had comorbid psychopathology, received benzodiazepines, and had early memories of frightening ICU experiences. In European studies, ICU diaries reduced posttraumatic stress disorder symptoms.

Effects of dynamic versus static parameter-guided fluid resuscitation in patients with sepsis: A randomized controlled trial.

Background: Fluid resuscitation is an essential component for sepsis treatment. Although several studies demonstrated that dynamic variables were more accurate than static variables for prediction of fluid responsiveness, fluid resuscitation guidance by dynamic variables is not standard for treatment. The objectives were to determine the effects of dynamic inferior vena cava (IVC)-guided versus (vs.) static central venous pressure (CVP)-guided fluid resuscitation in septic patients on mortality; and others, i.e., resuscitation targets, shock duration, fluid and vasopressor amount, invasive respiratory support, length of stay and adverse events. Methods: A single-blind randomized controlled trial was conducted at Thammasat University Hospital between August 2016 and April 2020. Septic patients were stratified by acute physiologic and chronic health evaluation II (APACHE II) <25 or ≥25 and randomized by blocks of 2 and 4 to fluid resuscitation guidance by dynamic IVC or static CVP. Results: Of 124 patients enrolled, 62 were randomized to each group, and one of each was excluded from mortality analysis. Baseline characteristics were comparable. The 30-day mortality rates between dynamic IVC vs. static CVP groups were not different (34.4% vs. 45.9%, p=0.196). Relative risk for 30-day mortality of dynamic IVC group was 0.8 (95%CI=0.5-1.2, p=0.201). Different outcomes were median (interquartile range) of shock duration (0.8 (0.4-1.6) vs. 1.5 (1.1-3.1) days, p=0.001) and norepinephrine (NE) dose (6.8 (3.9-17.8) vs. 16.1 (7.6-53.6) milligrams, p=0.008 and 0.1 (0.1-0.3) vs. 0.3 (0.1-0.8) milligram⋅kilogram -1, p=0.017). Others were not different. Conclusions: Dynamic IVC-guided fluid resuscitation does not affect mortality of septic patients. However, this may reduce shock duration and NE dose, compared with static CVP guidance.

Beneficial Effect of Water-Based Exercise Training on Exercise Capacity in COPD Patients-a Pilot Study.

Background: Chronic obstructive pulmonary disease (COPD) is a common, preventable, and treatable condition, characterized by persistent airflow limitation. Exercise training is a core component of pulmonary rehabilitation in people with COPD. Water-based exercise has been studied, but it remains unclear whether water-based exercise program leads to the improvement in respiratory function, muscle strength, balance ability, and exercise capacity. We aim to study the effect of an 8-week water-based exercise program on respiratory function, muscle strength, balance ability, and exercise capacity in people with COPD. Methods: Fourteen stable COPD participants (FEV1 56.8 ± 24.6%pred) were recruited and randomized into a water-based exercise or a land-based exercise group. Both groups were trained for 8 weeks, two sessions per week. Pulmonary function, respiratory muscle strength, peripheral muscle strength, balance ability, exercise capacity [6-min walking test (6MWT), incremental shuttle walk test (ISWT), and endurance shuttle walk test (ESWT)] were assessed at baseline and at the end of the program. ANCOVA was used to conduct between-group comparisons of outcomes after adjusting for pre-intervention values. Results: Baseline characteristics of participants were not significantly different between the two groups (p ≥ 0.05). After the 8-week training program, participants in the intervention group achieved larger gains in ESWT (Δ663.4 ± 279.5 vs. Δ45.4 ± 93.2 s, p = 0.001). In addition, maximal inspiratory pressure (MIP) was significantly increased more in the intervention group (Δ11.1 ± 7.8 vs. Δ1.1 ± 5.7 cmH2O, p = 0.026). However, no significant differences in pulmonary function, peripheral muscle strength, balance ability variables, 6MWD (p = 0.248), and ISWT (p = 0.506) were observed between the two groups. Conclusions: The water-based exercise program could be recommended to the COPD rehabilitation program for improving the endurance exercise capacity and inspiratory muscle strength.

Patient characteristics and outcomes of a home mechanical ventilation program in a developing country.

BACKGROUND: There are limited data on home mechanical ventilation (HMV) in developing countries. This study aimed to describe the patient characteristics, feasibility, and outcomes of an HMV program at a university hospital in Thailand. MATERIALS AND METHODS: Data were collected on all patients who were discharged with HMV between October 2014 and August 2015 at Thammasat University Hospital. RESULTS: Twelve patients (eight men and four women) underwent HMV. They were aged 71.5 ± 17.6 years; mean ± standard deviation. Indications for HMV were 6 neurologic diseases (4 amyotrophic lateral sclerosis, 1 multiple system atrophy, and 1 stroke), 2 chronic obstructive pulmonary disease (COPD), 1 tracheomalacia, and 3 combined neurologic diseases and respiratory diseases (2 stroke and COPD, 1 stroke and tracheomalacia). The duration of follow-up was 799.5 ± 780.5 days. The ratio of family income to cost of HMV usage was 77.2:1 ± 5.5:1. All patients had tracheostomies. Modes of HMV were biphasic positive airway pressure (66.7%), pressure-controlled ventilation (16.7%), pressure-support ventilation (8.3%), and volume-controlled ventilation (8.3%). Complications occurred in ten patients (83.3%), including tracheobronchitis (20 events) and ventilator-associated pneumonia (12 events). Overall mortality was 41.7% (5/12 patients), including two patients who died due to ventilator-associated pneumonia. There were no instances of ventilator malfunction. CONCLUSIONS: HMV is feasible for patients with neurological diseases and COPD in a developing country. The relatively high rate of complications indicates the need for more comprehensive clinical services for chronic ventilator-dependent patients in this setting.

Safety of Patient Mobilization and Rehabilitation in the Intensive Care Unit. Systematic Review with Meta-Analysis.

BACKGROUND: Early mobilization and rehabilitation of patients in intensive care units (ICUs) may improve physical function, and reduce the duration of delirium, mechanical ventilation, and ICU length of stay. However, safety concerns are an important barrier to widespread implementation. OBJECTIVES: To synthesize safety data regarding patient mobilization and rehabilitation in the ICU, including falls, removal of endotracheal tubes, removal or dysfunction of intravascular catheters, removal of other catheters/tubes, cardiac arrest, hemodynamic changes, and desaturation. DATA SOURCES: Systematic literature review, including searches of five databases. Eligible studies evaluated patients who received mobilization-related interventions in the ICU. Exclusion criteria included: (1) case series with fewer than 10 patients; (2) majority of patients under 18 years of age; and (3) data not reported to permit calculation of incidence of safety events. DATA EXTRACTION: Number of patients, mobilization/rehabilitation sessions, potential safety events, and events with negative consequences (e.g., requiring intervention or additional therapy). SYNTHESIS: Heterogeneity was assessed by I2 statistics, and bias assessed by the Newcastle-Ottawa Scale and Cochrane risk of bias assessment. The literature search identified 20,660 titles. There were 48 eligible publications evaluating 7,546 patients, with 583 potential safety events occurring in 22,351 mobilization/rehabilitation sessions. There was a total of 583 (2.6%) potential safety events with heterogeneity in the definitions for these events. For the safety event types that could be meta-analyzed, pooled incidences per 1,000 mobilization/rehabilitation sessions (95% confidence interval), were: hemodynamic changes, 3.8 (1.3-11.4), and desaturation, 1.9 (0.9-4.3). A total of 24 studies of 3,404 patients reported on any consequences of potential safety events (e.g., needing to increase dose of vasopressor due to mobility-related hypotension), with a frequency of 0.6% in 14,398 mobilization/rehabilitation sessions. CONCLUSIONS: Patient mobilization and physical rehabilitation in the ICU appears safe, with a low incidence of potential safety events, and only rare events having any consequences for patient management. Heterogeneity in the definition of safety events across studies emphasizes the importance of implementing existing consensus-based definitions.

Safety of physical therapy interventions in critically ill patients: a single-center prospective evaluation of 1110 intensive care unit admissions.

PURPOSE: Critical illness survivors commonly have impaired physical functioning. Physical therapy interventions delivered in the intensive care unit can reduce these impairments, but the safety of such interventions within routine clinical practice requires greater investigation. MATERIALS AND METHODS: We conducted a prospective observational study of routine physical therapy from July 2009 through December 2011 in the Johns Hopkins Hospital Medical Intensive Care Unit in Baltimore, MD. The incidence of 12 types of physiological abnormalities and potential safety events associated with physical therapy were monitored and evaluated for any additional treatment, cost, or length of stay. RESULTS: Of 1787 admissions of at least 24 hours, 1110 (62%) participated in 5267 physical therapy sessions conducted by 10 different physical therapists on 4580 patient-days. A total of 34 (0.6%) sessions had a physiological abnormality or potential safety event, with the most common being arrhythmia (10 occurrences, 0.2%) and mean arterial pressure greater than 140 mm Hg (8 occurrences; 0.2%) and less than 55 mm Hg (5 occurrences; 0.1%). Only 4 occurrences (0.1%) required minimal additional treatment or cost, without additional length of stay. CONCLUSIONS: In this large, single-center study, routine care physical therapy interventions were safe for critically ill patients.

Early Rehabilitation in the Intensive Care Unit: Preventing Physical and Mental Health Impairments.

Survivors of critical illness often experience new or worsening impairments in physical, cognitive and/or mental health, referred to as post-intensive care syndrome (PICS). Such impairments can be long-lasting and negatively impact survivors' quality of life. Early rehabilitation in the intensive care unit (ICU), while patients remain on life-support therapies, may reduce the complications associated with PICS. This article addresses evidence-based rehabilitation interventions to reduce the physical and mental health impairments associated with PICS. Implementation of effective early rehabilitation interventions targeting physical impairments requires consideration of 5 factors: barriers, benefits, feasibility, safety, and resources. Mental health impairments may be addressed by the following interventions: ICU diaries, early in-ICU psychological intervention, and post-ICU coping skills training. In both cases, a multidisciplinary team-based approach is paramount to the successful incorporation of early rehabilitation into routine practice in the ICU.

General anxiety symptoms after acute lung injury: predictors and correlates.

OBJECTIVE: Acute lung injury (ALI) is common in the intensive care unit (ICU), typically requiring life support ventilation. Survivors often experience anxiety after hospital discharge. We evaluated general anxiety symptoms 3 months after ALI for: (1) associations with patient characteristics and ICU variables, and (2) cross-sectional associations with physical function and quality of life (QOL). METHODS: General anxiety was assessed as part of a prospective cohort study recruiting patients from 13 ICUs at four hospitals in Baltimore, MD using the Hospital Anxiety and Depression Scale--Anxiety Subscale (HAD-A), with associations evaluated using multivariable linear and logistic regression models. RESULTS: Of 152 patients, 38% had a positive screening test for general anxiety (HAD-A≥8). Pre-ICU body mass index and psychiatric comorbidity were associated with general anxiety (OR, 95% confidence interval (CI): 1.06 (1.00, 1.13) and 3.59 (1.25, 10.30), respectively). No ICU-related variables were associated with general anxiety. General anxiety was associated with the number of instrumental ADL dependencies (Spearman's rho=0.22; p=0.004) and worse overall QOL as measured by EQ-5D visual analog scale (VAS) (rho=-0.34; p<0.001) and utility score (rho=-0.30; p<0.001), and by the SF-36 mental health domain (rho=-0.70; p<0.001) and Mental Component Summary score (rho=-0.73; p<0.001). CONCLUSION: Many patients have substantial general anxiety symptoms 3 months after ALI. General anxiety was associated with patient characteristics and impaired physical function and quality of life. Early identification and treatment of general anxiety may enhance physical and emotional function in patients surviving critical illnesses.
