Impact of Partnership Care Model on Quality of Life in Chronic Diseases: A Systematic Review and Meta-Analysis.

OBJECTIVE: To evaluate the effectiveness of the Partnership Care Model (PCM) on health-related quality of life (HRQoL) in adults with chronic diseases. Methods Data Sources/Study Setting: Existing literature dealing with the effect of HRQoL on chronic patients according to the HRQoL outcomes based on SF36 questionnaires. STUDY DESIGN: Systematic review and meta-analysis. DATA COLLECTION: Medline, PubMed, Scopus, Web of Science, Embase, Cochran database and Persian databases, including SID, Magiran, Iranmedex, and Irandoc, were searched according to the MeSH terms until May 15, 2022. Data analysis was made by using the random effects model and heterogeneity by I2 index, and all analyses were made by STATA vers.16 (Stata Corp, College Station, Texas, USA). PRINCIPAL FINDINGS: Three studies were included in the meta-analysis. Computing the common effect size, there was a significant intervention effect in all HRQoL dimensions, physical and mental subscales, as well as HRQoL total score. The results showed that there was significantly moderate to high substantial heterogeneity between studies except for vitality (I2=45.9%, P=0.157) and physical functioning (I2=30.9%, P=0.235) dimensions. CONCLUSION: According to the results of the study and realizing the efficiency of PCM on the eight dimensions of quality of life of chronic patients, it can be stated that this national model, which is in line with the culture and context of Iran, is effective, simple, efficient and reliable. It can be used in the promotion and improvement of various dimensions of HRQoL in chronic diseases.

New integrated weaning indices from mechanical ventilation: A derivation-validation observational multicenter study.

Background: To develop ten new integrated weaning indices that can predict the weaning outcome better than the traditional indices. Methods: This retrospective-prospective derivation-validation observational multicenter clinical trial (Clinical Trial.Gov, NCT01779297), was conducted on 1,175 adult patients admitted at 9 academic affiliated intensive care units (ICUs; 4 surgical and 5 medical), from Jan 2013 to Dec 2018. All patients, intubated and mechanically ventilated for at least 24 h and ready for weaning were enrolled. The study had two phases: at first, the threshold values of each index that best discriminate between a successful and an unsuccessful weaning outcome was determined among 208 patients in the derivation group. In the second phase, the predictive performance of these values was prospectively tested in 967 patients in the validation group. In the prospective-validation set we used Bayes' theorem to assess the probability of each test in predicting weaning. Results: In the prospective validation group, sensitivity, specificity, diagnostic accuracy, positive and negative predictive values, and finally area under the receiver operator characteristic curves and standard errors for each index (ten formulae) were calculated. Statistical values of ten formulae for aforesaid variables were higher than 87% (0.87-0.99). Conclusion: The new indices can be used for hospitalized patients in intensive care settings for accurate prediction of the weaning outcome.

Statin therapy in chronic viral hepatitis: a systematic review and meta-analysis of nine studies with 195,602 participants.

BACKGROUND: Conflicting data suggest that statins could cause chronic liver disease in certain group of patients, while improving prognosis in those with chronic viral hepatitis (CVH). PURPOSE: To quantify the potential protective role of statins on some main liver-related health outcomes in clinical studies on CVH patients.Data Sources: The search strategy was explored by a medical librarian using bibliographic databases, from January 2015 to April 2020.Data synthesis: The results showed no significant difference in the risk of mortality between statin users and non-users in the overall analysis. However, the risk of mortality significantly reduced by 39% in statin users who were followed for more than three years. Moreover, the risk of HCC, fibrosis, and cirrhosis in those on statins decreased by 53%, 45% and 41%, respectively. Although ALT and AST reduced slightly following statin therapy, this reduction was not statistically significant. LIMITATIONS: A significant heterogeneity among studies was observed, resulting from differences in clinical characteristics between statin users and non-users, study designs, population samples, diseases stage, comorbidities, and confounding covariates. CONCLUSION: Not only long-term treatment with statins seems to be safe in patients affected by hepatitis, but also it significantly improves their prognosis.

Impact of Religiosity on Delirium Severity Among Critically Ill Shi'a Muslims: A Prospective Multi-Center Observational Study.

This study assesses the impact of religiosity on delirium severity and patient outcomes among Shi'a Muslim intensive care unit (ICU) patients. We conducted a prospective observational cohort study in 21 ICUs from 6 Iranian academic medical centers. Delirium was assessed using the Confusion Assessment Method for the ICU (CAM-ICU) tool. Eligible patients were intubated, receiving mechanical ventilation (MV) for ≥ 48 h. Illness severity was assessed using Acute Physiology and Chronic Health Evaluation II (APACHE II) scores. A total of 4200 patients were enrolled. Patient religiosity was categorized as more (40.6%), moderate (42.3%), or less (17.1%) based on responses to patient and surrogate questionnaires. The findings suggest that lower pre-illness religiosity may be associated with greater delirium severity, MV duration, and ICU and hospital LOS. The lower mortality in the less religiosity group may be related in part to a greater proportion of female patients, but it remains unclear whether and to what extent greater religiosity impacted treatment decisions by patients and families. Further investigation is needed to validate and clarify the mechanism of the mortality findings.

Nutritional adequacy in critically ill patients: Result of PNSI study.

BACKGROUND & AIMS: Critically ill patients are provided with the intensive care medicine to prevent further complications, including malnutrition, disease progression, and even death. This study was intended to assess nutritional support and its' efficacy in the Intensive Care Units (ICUs) of Iran. METHODS: This cross-sectional study assessed 50 ICU's patients out of 25 hospitals in the 10 major regions of Iran's health system and was performed using the multistage cluster sampling design. The data were collected from patient's medical records, ICU nursing sheets, patients or their relatives from 2017 to 2018. Nutritional status was investigated by modified NUTRIC score and food frequency checklist. RESULTS: This study included 1321 ICU patients with the mean age of 54.8 ± 19.97 years, mean mNUTRIC score of 3.4 ± 2.14, and malnutrition rate of 32.6%. The mean time of first feeding was the second day and most of patients (66%) received nutrition support, mainly through enteral (57.2%) or oral (37%) route during ICU stay. The patients received 59.2 ± 37.78 percent of required calorie and 55.5 ± 30.04 percent of required protein. Adequate intake of energy and protein was provided for 16.2% and 10.7% of the patients, respectively. The result of regression analysis showed that the odds ratio of mNUTRIC score was 0.85 (95% confidence interval [CI] = 0.74-0.98) and APACHE II was 0.92 (95%CI = 0.89-0.95) for the prediction of energy deficiency. Nutrition intake was significantly different from patient's nutritional requirements both in terms of energy (p < 0.001) and protein (p < 0.001). Also, mean mNUTRIC score varied notably (p = 0.011) with changing in energy intake, defined as underfeeding, adequate feeding, and overfeeding. CONCLUSION: The present findings shown that, provided nutritional care for ICU patients is not adequate for their requirements and nutritional status.

Nutritional status of patients hospitalized in the intensive care unit: A comprehensive report from Iranian hospitals, 2018.

INTRODUCTION AND AIM: Malnutrition is a complication of hospitalization in critically ill patients. This event is occurred because of disease and therapeutic processes for curing the patients. Determination of nutritional status helps physicians and clinical nutritionists decide on the best regimen which should be prescribed for a patient. In the current study, we aimed to report the nutritional status ofpatientshospitalizedin the intensive care unit (ICU). METHOD OF STUDY: We used three standard tolls, including Subjective global assessment (SGA), Nutrition Risk in the Critically Ill (NUTRIC) Score and nutrition risk screening (NRS) questionnaires via a multi-stage sampling for different ICU wards of 32 university hospitals in Iran. Frequencies and rates of nutritional scores, comparative studies, and determined agreement of scoring systems and nutritional status in any ward of hospitals were evaluated. RESULTS: There were 771 males and 540 female Cancer and trauma patients had the best and worst nutritional scores, respectively. Using NRS and NUTRIC, the low-risk scores were more frequent than thehigh-riskscores among ICU patients. SGA showed that most patients were in grades A (well nutritional status) or B (moderate nutritional status), andfew caseswere in grade C (poor nutritional status).The high-risk nutritional score wasobtained for older patients. NUTRIC and NRS had better agreement for diagnosis and differentiation of malnutrition than NUTRIC-SGA or NRS-SGA pairs. However, there was no strong agreement between the mentioned pairs. CONCLUSION: Nutritional status of patients hospitalized in ICU wards in Iran wassomewhat better than other countries that this could be due to the highly observed guidelines of patient's care in Iran. Anyway,it is suggested that a more precise tool of nutritional scoresto be validated for patients hospitalized in ICU·In addition, better medical care needs a well evaluation of nutritional insufficiencies and what is necessary for compensation using complementary regimens.

Real-time compression feedback for patients with in-hospital cardiac arrest: a multi-center randomized controlled clinical trial.

OBJECTIVE: To determine if real-time compression feedback using a non-automated hand-held device improves patient outcomes from in-hospital cardiac arrest (IHCA). METHODS: We conducted a prospective, randomized, controlled, parallel study (no crossover) of patients with IHCA in the mixed medical-surgical intensive care units (ICUs) of eight academic hospitals. Patients received either standard manual chest compressions or compressions performed with real-time feedback using the Cardio First Angel™ (CFA) device. The primary outcome was sustained return of spontaneous circulation (ROSC), and secondary outcomes were survival to ICU and hospital discharge. RESULTS: One thousand four hundred fifty-four subjects were randomized; 900 were included. Sustained ROSC was significantly improved in the CFA group (66.7% vs. 42.4%, P < 0.001), as was survival to ICU discharge (59.8% vs. 33.6%) and survival to hospital discharge (54% vs. 28.4%, P < 0.001). Outcomes were not affected by intra-group comparisons based on intubation status. ROSC, survival to ICU, and hospital discharge were noted to be improved in inter-group comparisons of non-intubated patients, but not intubated ones. CONCLUSION: Use of the CFA compression feedback device improved event survival and survival to ICU and hospital discharge. TRIAL REGISTRATION: The study was registered with Clinicaltrials.gov (NCT02845011), registered retrospectively on July 21, 2016.

Comparison of non-invasive to invasive oxygenation ratios for diagnosing acute respiratory distress syndrome following coronary artery bypass graft surgery: a prospective derivation-validation cohort study.

OBJECTIVE: To determine if non-invasive oxygenation indices, namely peripheral capillary oxygen saturation (SpO2)/fraction of inspired oxygen (FiO2) and partial pressure of alveolar oxygen (PAO2)/FiO2 may be used as effective surrogates for the partial pressure of arterial oxygen (PaO2)/FiO2. Also, to determine the SpO2/FiO2 and PAO2/FiO2 values that correspond to PaO2/FiO2 thresholds for identifying acute respiratory distress syndrome (ARDS) in patients following coronary artery bypass graft (CABG) surgery. METHODS: A prospective derivation-validation cohort study in the Open-Heart ICU of an academic teaching hospital. Recorded variables included patient demographics, ventilator settings, chest radiograph results, and SPO2, PaO2, PAO2, SaO2, and FiO2. Linear regression modeling was used to quantify the relationship between indices. Receiver operating characteristic (ROC) curves were used to determine the sensitivity and specificity of the threshold values. RESULTS: One-hundred seventy-five patients were enrolled in the derivation cohort, and 358 in the validation cohort. The SPO2/FiO2 and PAO2/FiO2 ratios could be predicted well from PaO2/FiO2, described by the linear regression models SPO2/FiO2 = 71.149 + 0.8PF and PAO2/FiO2 = 38.098 + 2.312PF, respectively. According to the linear regression equation, a PaO2/FiO2 ratio of 300 equaled an SPO2/FiO2 ratio of 311 (R2 0.857, F 1035.742, < 0.0001) and a PAO2/FiO2 ratio of 732 (R2 0.576, F 234.887, < 0.0001). The SPO2/FiO2 threshold of 311 had 90% sensitivity, 80% specificity, LR+ 4.50, LR- 0.13, PPV 98, and NPV 42.1 for the diagnosis of mild ARDS. The PAO2/FiO2 threshold of 732 had 86% sensitivity, 90% specificity, LR+ 8.45, LR- 0.16, PPV 98.9, and NPV 36 for the diagnosis of mild ARDS. SPO2/FiO2 had excellent discrimination ability for mild ARDS (AUC ± SE = 0.92 ± 0.017; 95% CI 0.889 to 0.947) as did PAO2/FiO2 (AUC ± SE = 0.915 ± 0.018; 95% CI 0.881 to0.942). CONCLUSIONS: PaO2 and SaO2 correlated in the diagnosis of ARDS, with a PaO2/FiO2 of 300 correlating to an SPO2/ FiO2 of 311 (Sensitivity 90%, Specificity 80%). The SPO2/ FiO2 ratio may allow for early real-time rapid identification of ARDS, while decreasing the cost, phlebotomy, blood loss, pain, skin breaks, and vascular punctures associated with serial arterial blood gas measurements.
