RESUMO

Introduction: The process of weaning patients off mechanical ventilation (MV) is difficult and complex. Critical care nurses must maintain continuity of care for patients undergoing MV weaning, assess patients' overall condition, and meet patients' needs. Objectives: The study aimed to explore clinical factors of MV weaning success and 28-day survival among patients with acute respiratory distress syndrome secondary to COVID-19. Methods: This prospective observational study was conducted on 90 newly admitted patients in the general intensive care unit Assiut Univeristy Main Hospital in Egypt from October 2021 to March 2022. The researchers applied a standard weaning protocol for all of the patients in this study and then assessed the outcome variables: success or failure of weaning trials from a mechanical ventilator, and 28-day survival. Results: In total, 50 (55.6%) patients were successfully weaned from MV, and 45 (50%) patients survived at 28 days. In a multivariate regression analysis, dynamic compliance (OR, 1.115; 95% CI, 1.010-1.230, p = .031*), lymphocyte count (OR, 3.025; 95% CI, 1.322-6.923, p = .009*), urine output (OR, 1.002; 95% CI, 1.001-1.004, p = .002*), and alanine aminotransferase (ALT; OR, 0.993; 95% CI, 0.988-0.999, p = .017*) were significantly associated with weaning success. In addition, age (OR, 1.058; 95% CI, 1.015-1.102; p = .007*), lymphocyte count (OR, 3.304; 95% CI, 1.348-8.100; p = .009*), urine output (OR, 1.003; 95% CI, 1.001-1.004; p = .001*), and ALT (OR, 0.994; 95% CI, 0.989-0.99, p = .015*) were significantly associated with survival at 28 days. Conclusion: Dynamic lung compliance, lymphocyte count, urine output, and ALT were found to be predictive parameters that may affect the success of weaning off MV. Additionally, it was found that age, lymphocyte count, urine output, and ALT are predictors of survival at 28 days. We recommend further studies with larger, more systematic samples and complete follow-up, focusing on pulmonary function and quality of life in postweaning patients with acute respiratory distress syndrome.

RESUMO

Objective: Depression is a common comorbidity in patients with asthma with a significant impact on clinical management. However, little information is available about physicians' perceptions and current practices in identifying and managing depression in individuals with asthma in Saudi Arabia. Thus, this study aims to assess physicians' views and current practices of identifying and managing depression in patients with asthma in Saudi Arabia. Methods: A cross-sectional study was employed. Between September 2022 and February 2023, an online survey was distributed to physicians (general practitioners and family, internal and pulmonary medicine specialists) in Saudi Arabia. Descriptive statistics were performed to analyze the collected responses. Results: Out of 1800 invited participants, a total of 1162 physicians completed the online survey. Nearly 40% of the respondents received adequate training for managing depression. More than 60% of physicians reported that depression interferes with self-management and worsens asthma symptoms, while 50% viewed the importance of regular screening for depression. Less than 40% (n=443) aim to identify depression during patients' visits. Of those, only 20% always screen for depression in asthma patients. Physicians show a low level of confidence when asking patients about their feelings (30%), being able to recognize depression (23%), and knowing if patients have depression (23%). The most common barriers linked to recognizing depression are high workload (50%), lack of time to screen for depression (46%), limited knowledge about depression (42%), and poor training (41%). Conclusion: The rate of recognizing and confidently managing depression in asthmatic patients is significantly low. This is attributed to high workload, poor training, and limited knowledge about depression. There is a need to support psychiatric training and implement a systematic approach to depression detection in clinical settings.

RESUMO

OBJECTIVE: To investigate physicians' perceptions and current practices of identifying and managing depression in patients with chronic obstructive pulmonary disease (COPD). DESIGN: A cross-sectional online survey was employed between March and September 2022. SETTINGS: Saudi Arabia. PARTICIPANTS: 1015 physicians, including general practitioners and family, internal and pulmonary medicine specialists. PRIMARY OUTCOME MEASURES: Physicians' perceptions, confidence, practices and barriers to recognising and managing depression in patients with COPD. RESULTS: A total of 1015 physicians completed to the online survey. Only 31% of study participants received adequate training for managing depression. While 60% of physicians reported that depression interferes with self-management and worsens COPD symptoms, less than 50% viewed the importance of regular screening for depression. Only 414 (41%) physicians aim to identify depression. Of whom, 29% use depression screening tools, and 38% feel confident in discussing patients' feelings. Having adequate training to manage depression (OR: 2.89; 95% CI: 2.02 to 3.81; p<0.001) and more years of experience (OR: 1.25; 95% CI: 1.08 to 1.45; p=0.002) were associated with the intention to detect depression in COPD patients. The most common barriers linked to recognising depression are poor training (54%), absence of standard procedures (54%) and limited knowledge about depression (53%). CONCLUSION: The prevalence of identifying and confidently managing depression in patients with COPD is suboptimal, owing to poor training, the absence of a standardised protocol and inadequate knowledge. Psychiatric training should be supported in addition to adopting a systematic approach to detect depression in clinical practice.

RESUMO

Although personal resilience and supervisory support are known to reduce the impact of burnout and quitting intention, there is limited data available to explore these relationships among healthcare professionals (HCPs) in Saudi Arabia. This study aimed to assess the prevalence of burnout and explore its association with resilience, supervisory support, and intention to quit among Saudi Arabian HCPs. METHODS: A cross-sectional survey was distributed to a convenience sample of HCPs between April and November 2022. Participants responded to socio-demographic questions, the Maslach Burnout Inventory-Human Services Survey for Medical Personnel (MBI-HSS (MP)), the Connor-Davidson resilience scale 10 (CD-RISC 10), and the Perceived of Supervisor Support Scale (PSS). Descriptive, inferential, correlation, and logistic regression tests were performed for data analyses. RESULTS: Of the 1174 HCPs included in the analysis, 77% were presented with high burnout levels: 58% with emotional exhaustion (EE), 72% with depersonalization (DP), and 66% with low personal accomplishment (PA). Females were associated with increased odds of burnout (OR: 1.47; 95% CI: 1.04-2.06) compared to males. Burnout and its subscales were associated with higher intention to leave practice, with 33% of HCPs considering quitting their jobs. Furthermore, HCPs reported a low resilience score overall, and negative correlations were found between EE (r = -0.21; p < 0.001) and DP (r = -0.12; p < 0.01), and positive correlation with low PA (r = 0.38; p < 0.001). In addition, most HCPs perceived supervisory support as low, and it is associated with increased burnout and quitting intention. CONCLUSION: Burnout is common among HCPs across all clinical settings and is associated with higher intention to quit and low resilience and supervisory support. Workplace management should provide a supportive workplace to reduce burnout symptoms and promote resiliency.

RESUMO

OBJECTIVES: To assess the attitude of healthcare providers (HCPs) towards the delivering of pulmonary rehabilitation (PR) to patients with chronic obstructive pulmonary disease (COPD) and identify factors and barriers that might influence referral. DESIGN: A cross-sectional online survey consisting of nine multiple-choice questions. SETTINGS: Saudi Arabia. PARTICIPANTS: 980 HCPs including nurses, respiratory therapists (RT) and physiotherapists. PRIMARY OUTCOME MEASURES: HCPs attitudes towards and expectations of the delivery of PR to COPD patients and the identification of factors and barriers that might influence referral in Saudi Arabia. RESULTS: Overall, 980 HCPs, 53.1% of whom were men, completed the survey. Nurses accounted for 40.1% of the total sample size, and RTs and physiotherapists accounted for 32.1% and 16.5%, respectively. The majority of HCPs strongly agreed that PR would improve exercise capacity 589 (60.1%), health-related quality of life 571 (58.3%), and disease self-management in patients with COPD 589 (60.1%). Moreover, the in-hospital supervised PR programme was the preferred method of delivering PR, according to 374 (38.16%) HCPs. Around 85% of HCPs perceived information about COPD, followed by smoking cessation 787 (80.3%) as essential components of PR besides the exercise component. The most common patient-related factor that strongly influenced referral decisions was 'mobility affected by breathlessness' (64%), while the 'availability of PR centres' (61%), the 'lack of trained HCPs' (52%) and the 'lack of authority to refer patients' (44%) were the most common barriers to referral. CONCLUSION: PR is perceived as an effective management strategy for patients with COPD. A supervised hospital-based programme is the preferred method of delivering PR, with information about COPD and smoking cessation considered essential components of PR besides the exercise component. A lack of PR centres, well-trained staff and the authority to refer patients were major barriers to referring patients with COPD. Further research is needed to confirm HCP perceptions of patient-related barriers.

RESUMO

Purpose: Ventilator-associated pneumonia (VAP) is one of the most common infections in intensive care units (ICU) with a 6-52% incidence. The VAP mortality rate is 50% to 70%. Medical professionals (MPs) working in the ICU are expected to follow the guidelines to prevent VAP. The study aimed to assess the performance of MPs in preventing VAP and to associate the performance with the baseline information. Methods: An observational cross-sectional study was conducted in the ICUs of selected hospitals in eastern Saudi Arabia. A total of 152 MPs were selected by random sampling. A structured questionnaire including baseline information, knowledge and performance-related questions was used to collect the data. Frequency, mean, and chi-square tests were used for analysis. Results: Out of 152 MPs, 40.8% had adequate and 7.9% had inadequate knowledge. A high mean score of 12.9 ± 2.2 was obtained by physicians, followed by 11.3 ± 1.6 by nurses, 9.8 ± 2.2 by RTs, and 8.6 ± 2.1 by interns. Overall, 52.6% had satisfactory performance. Approximately 57.9% and 67.8% of MPs cleaned their hands before touching the patient and the ventilator, respectively. Many (79.6%) MPs used personal protective equipment in the ICU. Some (47.4%) of the MPs changed the patient's position regularly. About 77.6% of MPs followed the sterile technique when suctioning the airway. There was a significant association found between the performance of MPs on the prevention of VAP with age (p < 0.001), designation (p < 0.05), professional experience (p < 0.05), managing chronic obstructive pulmonary disease conditions (p < 0.05) and training attended (p < 0.001). Conclusion: Although some of the MPs had satisfactory performance regarding VAP prevention in the ICU, more attention should be paid to training them on clinical guidelines to improve health care quality and reduce the rate of VAP.

RESUMO

OBJECTIVE: This study was conducted to determine the clinical practice and barriers of ventilatory support management in COVID-19 patients in Saudi Arabia among respiratory therapists. METHODS: A validated questionnaire comprising three parts was distributed to all critical care respiratory therapists registered with the Saudi Society for Respiratory Care through the official social networks. RESULTS: A total of 74 respiratory therapists completed the survey. The mean (±standard deviation) of intensive care unit beds was 67 ± 79. Clinical presentation (54%) and arterial blood gas (38%) were the two main diagnostic tools used to initiate ventilatory support. While protocols for the initiation of invasive mechanical ventilation (IMV; 81%) were widely available, participants had limited availability of protocols for the use of non-invasive ventilation (NIV; 34%) and high-flow nasal cannula (HFNC; 34%). In mild cases of COVID-19, most respondents used HFNC (57%), while IMV was mostly used in moderate (43%) and severe (93%) cases. Regular ventilator check was mostly done every 4 h (57%). BiPAP (47.3%) and full-face masks (45.9%) were the most used mode and interface, respectively, while pressure-regulated volume control (55.4%) and pressure control (27%) were the most used mechanical ventilation modes for COVID-19 patients. In terms of use of proning, 62% used it on IMV, while 26% reported using awake proning. Staff shortage (51.4%), personal protective equipment (PPE) shortage (51.4%), increased workload (45.9%), inadequate training (43.2%) and lack of available protocols and policies (37.8%) were the main barriers. CONCLUSION: Ventilatory support management of COVID-19 in Saudi Arabia was inconsistent with the global practice, lacked uniformity, and there was limited use of standard protocols/treatment guidelines. Shortage of staff and PPE, increased workload and insufficient training were the most prevalent barriers.

RESUMO

Biomedical waste (BMW) management is an essential practice of healthcare professionals (HCPs) for preventing health and also environmental hazards. Coronavirus disease (COVID-19) has become a global pandemic, posing significant challenges for healthcare sectors. A cross-sectional study was performed to assess the knowledge, practice, and attitude on BMW management among HCPs when taking care of patients with COVID-19 and associated with demographic variables. From Al-Ahsa healthcare sectors, 256 HCPs were selected randomly, of which 105 (41%) had excellent knowledge, 87 (34%) had good knowledge, and 64 (25%) had poor knowledge with a mean score of 13.1 ± 3.6. A higher mean score was (14.4 ± 3.2) obtained by physicians, and (13.6 ± 3.8) nurses than the other HCPs. Regarding practice, 72 (28.1%) HCPs used and discarded PPE while handling biomedical wastes. Additionally, 88 (34.4%) followed proper hand hygiene before and after each procedure and whenever needed. Physicians, nurses, and respiratory therapists had a more favorable attitude than other HCPs. There was a statistically significant association found among knowledge level and educational qualification (p < 0.0001), gender (p < 0.001), and work experience (p < 0.05). Emphasis is needed to train all HCPs regarding proper BMW management during this pandemic to prevent infection transmission.

RESUMO

BACKGROUND: As the global outbreak of COVID-19 continues to ravage the world, it is important to understand how frontline clinicians manage ventilatory support and the various limiting factors. METHODS: An online survey composed of 32 questions was developed and validated by an international expert panel. RESULTS: Overall, 502 respondents from 40 countries across six continents completed the survey. The mean number (±SD) of ICU beds was 64 ± 84. The most popular initial diagnostic tools used for treatment initiation were arterial blood gas (48%) and clinical presentation (37.5%), while the national COVID-19 guidelines were the most used (61.2%). High flow nasal cannula (HFNC) (53.8%), non-invasive ventilation (NIV) (47%), and invasive mechanical ventilation (IMV) (92%) were mostly used for mild, moderate, and severe COVID-19 cases, respectively. However, only 38.8%, 56.6% and 82.9% of the respondents had standard protocols for HFNC, NIV, and IMV, respectively. The most frequently used modes of IMV and NIV were volume control (VC) (36.1%) and continuous positive airway pressure/pressure support (CPAP/PS) (40.6%). About 54% of the respondents did not adhere to the recommended, regular ventilator check interval. The majority of the respondents (85.7%) used proning with IMV, with 48.4% using it for 12-16 hours, and 46.2% had tried awake proning in combination with HFNC or NIV. Increased staff workload (45.02%), lack of trained staff (44.22%) and shortage of personal protective equipment (PPE) (42.63%) were the main barriers to COVID-19 management. CONCLUSION: Our results show that general clinical practices involving ventilatory support were highly heterogeneous, with limited use of standard protocols and most frontline clinicians depending on isolated and varied management guidelines. We found increased staff workload, lack of trained staff and shortage of PPE to be the main limiting factors affecting global COVID-19 ventilatory support management.

RESUMO

BACKGROUND: Clinical and research utility of non-cardiac ultrasound (US) in chronic obstructive pulmonary disease (COPD) has been widely investigated. However, there is no systematic review assessing the clinical values of non-cardiac US techniques in COPD. METHODS: We systematically searched electronic databases from inception to 24 June 2020. Two independent reviewers in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines extracted data. A narrative synthesis of the results was conducted considering non-cardiac US techniques that looked for diaphragm, muscles and bones in patients with COPD. RESULTS: In total, 2573 abstracts were screened, and 94 full-text papers were reviewed. A total of 54 studies met the inclusion criteria. Thirty-five studies assessed the diaphragm, while 19 studies evaluated different muscles, including limb muscles and pulmonary lesions in COPD using US. Of the 54 included studies, 30% (16/54) evaluated the changes in either limb muscles or diaphragmatic features before and after physical interventions; 67% (36/54) assessed the correlations between sonographic features and COPD severity. Indeed, 14/15 and 9/13 studies reported a significant reduction in diaphragm excursion and thickness in COPD compared with healthy subjects, respectively; this was correlated significantly with the severity and prognosis of COPD. Three studies reported links between diaphragm length and COPD, where lower diaphragm length correlated with poorer prognosis and outcomes. Quadriceps (rectus femoris), ankle dorsiflexor (tibialis anterior) and vastus lateralis were the most common muscles in COPD assessed by US. More than 70% (12/17) of the studies reported a significant reduction in the cross-sectional area (CSA) of the rectus femoris, rectus femoris and vastus lateralis thickness in COPD compared with healthy subjects. Quadriceps CSA and thickness correlated positively with COPD prognosis, in which patients with reduced quadriceps CSA and thickness have higher risk of exacerbation, readmission and death. CONCLUSION: US measurements of diaphragm excursion and thickness, as well as lower limb muscles strength, size and thickness, may provide a safe, portable and effective alternative to radiation-based techniques in diagnosis and prognosis as well as tracking improvement postintervention in patients with COPD.

RESUMO

BACKGROUND: Readmission rates following hospitalisation for COPD exacerbations are unacceptably high, and the contributing factors are poorly understood. Our objective was to summarise and evaluate the factors associated with 30- and 90-day all-cause readmission following hospitalisation for an exacerbation of COPD. METHODS: We systematically searched electronic databases from inception to 5 November 2019. Data were extracted by two independent authors in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Study quality was assessed using a modified version of the Newcastle-Ottawa Scale. We synthesised a narrative from eligible studies and conducted a meta-analysis where this was possible using a random-effects model. RESULTS: In total, 3533 abstracts were screened and 208 full-text manuscripts were reviewed. A total of 32 papers met the inclusion criteria, and 14 studies were included in the meta-analysis. The readmission rate ranged from 8.8-26.0% at 30 days and from 17.5-39.0% at 90 days. Our narrative synthesis showed that comorbidities, previous exacerbations and hospitalisations, and increased length of initial hospital stay were the major risk factors for readmission at 30 and 90 days. Pooled adjusted odds ratios (95% confidence intervals) revealed that heart failure (1.29 (1.22-1.37)), renal failure (1.26 (1.19-1.33)), depression (1.19 (1.05-1.34)) and alcohol use (1.11 (1.07-1.16)) were all associated with an increased risk of 30-day all-cause readmission, whereas being female was a protective factor (0.91 (0.88-0.94)). CONCLUSIONS: Comorbidities, previous exacerbations and hospitalisation, and increased length of stay were significant risk factors for 30- and 90-day all-cause readmission after an index hospitalisation with an exacerbation of COPD.

RESUMO

Introduction: Advances in technology offer various solutions that might help optimize the care provided to patients living with chronic non-communicable diseases such as chronic obstructive pulmonary disease (COPD). However, the efficacy of tele-health in COPD is still controversial. Despite this, there appears to be widespread adoption of this technology. Aim: To explore the international use of tele-heath for COPD, to assess the perceptions of clinicians employing tele-health in COPD, and to summarize the techniques that have been used by health care providers to personalize alarm limits for patients with COPD enrolled on tele-health programs. Methods: A cross-sectional survey consisting of 15 questions was distributed and advertised to health care professionals worldwide. Questions were designed to cover five different aspects of tele-health in COPD: purpose of use, equipment type, clinician perceptions, variables monitored, and personalization of alarm limits. Results: A total of 138 participants completed the survey from 29 different countries. As high as 59% of the participants had ever used tele-health for COPD, and 33% still provided tele-health services to patients with COPD. Tele-health was most commonly used for baseline monitoring, with 90% believing it to be effective. The three most commonly monitored variables were oxygen saturation, heart rate, and the use of rescue medication. Conclusion: Twenty-nine different countries use tele-health for managing COPD and therefore there is widespread international use of tele-health in COPD. The majority of providers thought tele-health was effective despite evidence to the contrary.

RESUMO

BACKGROUND: Patients with chronic obstructive pulmonary disease (COPD) have elevated cardiovascular risk, and cardiovascular disease is a major cause of death in COPD. The current literature indicates that changes in cardiovascular risk during pulmonary rehabilitation (assessed using aortic stiffness) are heterogeneous suggesting that there may be sub-groups of patients who do and do not benefit. OBJECTIVES: To investigate the characteristics of COPD patients who do and do not experience aortic stiffness reduction during pulmonary rehabilitation, examine how changes relate to physical activity and exercise capacity, and assess whether changes in aortic stiffness are maintained at 6 weeks following rehabilitation. METHODS: We prospectively measured arterial stiffness (aortic pulse-wave velocity), exercise capacity (Incremental Shuttle Walk Test) and physical activity (daily step count) in 92 COPD patients who started a six week pulmonary rehabilitation programme, 54 of whom completed rehabilitation, and 29 of whom were re-assessed six weeks later. RESULTS: Whilst on average there was no influence of pulmonary rehabilitation on aortic stiffness (pre- vs. post pulse-wave velocity 11.3 vs. 11.1 m/s p = 0.34), 56% patients responded with a significant reduction in aortic stiffness. Change in aortic stiffness (absolute and/or percentage) during rehabilitation was associated with both increased physical activity (rho = - 0.30, p = 0.042) and change in exercise capacity (rho = - 0.32, p = 0.02), but in multivariable analysis most closely with physical activity. 92% of the responders who attended maintained this response six weeks later. CONCLUSION: Elevated aortic stiffness in COPD is potentially modifiable in a subgroup of patients during pulmonary rehabilitation and is associated with increased physical activity.
