RESUMEN
Using cell phones by nurses can affect the quality of care. This study aimed to explore the consequences of using cell phones by nurses in hospitals. A qualitative approach was used. Data were collected through semi-structured interviews. Nursing staff, patients, and their relatives participated in this study. Categories of "emotionless care," "neglect in care," "impaired professional behavior" and a main theme of "Personal cell phone is a barrier to effective nursing care" extracted. Using cell phone during work could jeopardize patients' safety and ruins the nursing profession image. It is necessary to formulate guidelines on how to use cell phones in hospitals.
RESUMEN
Background: Healthcare-associated infections (HAIs) in intensive care unit (ICU) patients significantly complicate the normal hospitalization process and affect patients' condition, length of hospitalization, mortality, and treatment cost. In this study, we aimed to determine the prevalence and economic burden of HAIs. Methods: The study involved all patients with a confirmed HAIs (based on CDC/NHSN case-definitions); in the general ICU of a tertiary university hospital in Tehran, from April 2020 to March 2021. The patients' information, including length of hospitalization, outcome, type and cost of prescribed antibiotics, were recorded. Results: During the study period, 119 HAIs were found in 1395 (43% F / 57% M) patients. The prevalence of nosocomial infections was 8.53%. The mean duration of hospitalization in all ICU patients was 4.7 ± 3.1 days, and 31.85 ± 18.96 days in patients with HAIs. The most common organisms involved in HAIs are Acinetobacter baumannii (54.6%), Klebsiella pneumoniae (30.3%), E. coli (15.1%), and Enterococcus spp. (12%). Incidence density of ventilator-associated pneumonia (VAP), central line-associated bloodstream infection (CLA-BSI), and catheter-associated urinary tract infection (CA-UTI) per 1000 device-days were 36.08, 17.57, and 8.86, respectively. The total cost of antibiotics for HAIs was 105,407. Among these, the highest consumption costs were for carbapenems, followed by colistin and caspofungin. Conclusion: This study showed the high burden of nosocomial infections in ICUs. Strategies for more strict infection prevention and control are necessary to reduce this burden.
RESUMEN
BACKGROUND: The aesthetics of everyday life improves physical and mental health and social communication. This study aims to develop and test a novel instrument that assesses the aesthetics of the everyday life of older adults. METHODS: A mixed-methods study with a sequential exploratory approach was conducted from November 2021 to December 2022. Item generation and questionnaire formation were developed through interviews with older adults and a literature review (stage 1). A cross-sectional study was then conducted to test the psychometric properties of the novel scale among 380 older adults referred to Urban Comprehensive Health Service Centers (stage 2). The construct validity was tested via exploratory factor analysis (EFA) and with the principal component analysis method. Internal consistency and reliability of the scale were evaluated with Cronbach's alpha and test-retest with a 2-week interval. RESULTS: The initial scale was prepared with 39 items. In stage 2, EFA revealed a seven-factor model with 34 items. Internal consistency was acceptable for extracted sub-scales (Cronbach's alpha range: 0.67- 0.93) and the total score (0.926). The intra-class correlation coefficient for test-retest reliability was 0.90. CONCLUSIONS: The AELSA is a valid and reliable instrument for evaluating the aesthetics of everyday life in older adults. the scale will help policymakers in formulating interventions to improve mental health and well-being in older adults. Moreover, Further studies is need to provide more support of construct validity.

BACKGROUND: Missed care refers to the omission or delay in performing any aspect of patient's care (either a part of the care or the entire care). Currently, missed care has become a growing concern at the international level, which threatens the quality and safety of care and cases many unwanted consequences. This study aims to investigate the frequency and types of missed nursing care in the emergency departments of selected hospitals affiliated to Tehran University of Medical Sciences. METHODS: This is a cross-sectional and descriptive- observational study that was conducted with the aim of determining the frequency and types of missed nursing care in the emergency departments of selected hospitals affiliated to Tehran University of Medical Sciences from January 2020 to June 2020. The research community included all nursing care offered in the designated areas, as well as all nurses working in the emergency departments of selected hospitals. Finally, 146 nurses were selected by census method. The information was collected by self-reporting method and the researcher's observation. Demographic information questionnaire, a researcher-made checklist were used to determine the frequency and types of missed nursing care. 384 observations were made for each item. Descriptive statistics methods were used to analyze the data. RESULTS: The area of checking equipment and emergency trolley(mean = 81.80) had the lowest and the area of patient communication(mean = 55.72) had the highest level of missed care. CONCLUSIONS: The level of missed nursing care in the emergency departments of selected hospitals affiliated to Tehran University of Medical Sciences was found to be high and the highest amount was related to the field of communication with the patient. Therefore, it is recommended that the details of missed nursing care in each area should be considered by nursing managers.

BACKGROUND: Aesthetics of everyday life are associated with the physical, mental, and social health of older adults, leading them to experience a successful old age. This study aimed to examine the aesthetics of everyday life and its related factors among older adults in Kashan from 2021 to 2022. METHODS: This cross-sectional study consisted of 350 older adults who were referred to Urban Comprehensive Health Service Centers (UCHSC) in Kashan. Sampling was done by a two-stage method (cluster, random). The data collection was performed with a background information questionnaire and the Elderly's Perception of Everyday Aesthetics scale (EPEA-S). Data were analyzed using an independent t-test, analysis of variance, Pearson's correlation coefficient, and multiple linear regression tests in the SPSS software. RESULTS: The mean age of the participants was 69.56 ± 6.63 years. The mean score of aesthetics of everyday life in older adults was 133.02 ± 14.73, with the family and others subscale receiving the highest score. The univariate test indicated a statistically significant correlation between age, employment status, education, income, smoking, social activities, physical activities, interest in artistic works, and the aesthetics of everyday life in older adults (P < 0.01). Multivariate linear analysis showed that age, employment status, smoking, income, social activities, physical activities, and interest in artistic works predicted and explained 28% of the variance of life aesthetics in older adults (R2 = 0.28). CONCLUSIONS: The aesthetics of everyday life of the Iranian older adults were in a good range. Healthcare providers and families of older adults can use this concept to enhance the elderly's physical, mental, and social health.

Background and Objectives: Antibacterial resistance (AMR) is a serious threat and major concern, especially in developing countries. Therefore, we aimed to determine phenotypical patterns of resistance to antibiotics in COVID-19 patients with associated bacterial infection in intensive care units. Materials and Methods: In this cross-sectional study, 6524 COVID-19 patients admitted for more than 48 h in the ICUs of Imam Khomeini Complex Hospital (IKCH) in Tehran from March 2020 to January 2022 were included in the study with initial diagnosis of COVID-19 (PCR test and chest imaging). Data were collected regarding severity of the illness, primary reason for ICU admission, presence of risk factors, presence of infection, length of ICU and hospital stay, microbial type, and antibiotic resistance. In this study, the pattern of antibiotic resistance was determined using the Kirby-Bauer disk diffusion method. Results: In this study, 439 (37.5%) were ventilator-related events (VAEs), and 46% of all hospitalized patients had an underlying disease. The most common microorganisms in COVID-19 patients were carbapenem resistant Klebsiella pneumoniae (KPCs) (31.6%), Escherichia coli (E. coli) (15.8%), and Acinetobacter baumannii (A. baumannii) (15.7%), respectively. Prevalence of vancomycin-resistant enterococci (VRE) and KPCs were 88% and 82%, respectively. Conclusion: A study on AMR surveillance is the need of the hour as it will help centers to generate local antibiograms that will further help formulate national data. It will guide doctors to choose the appropriate empiric treatment, and these studies will be the basis for establishing antimicrobial surveillance and monitoring and regulating of the use of antimicrobials.
RESUMEN
INTRODUCTION: Geriatric hip fracture are a common and disruptive public health problem worldwide. Surgical Site Infection (SSI) can be a devastating complication of this injury. By identifying these factors, the adverse outcomes of elderly hip fractures can be prevented. The objective of this study was to identify factors affecting the incidence of surgical site infection after geriatric hip fracture surgery. METHODS: In this retrospective study, 440 patients (60 years or older) underwent hip surgery at Imam Khomeini Hospital Complex were selected based on census between April 2017 and March 2020. Demographics information, and additional comorbidities and operation-related variables were extracted and analyzed. Data analyses were performed by descriptive statistics and inferential statistics. SPSS-19 software was used in this study and P values less than 0.05 were considered significant. RESULTS: The results of univariate analyzes showed that the type of surgery (p=0.005), readmission (p=0.0001) and level of self-care (p=0.001) were significantly associated with Surgical Site Infection (SSI). The results of regression analysis showed that history of readmission and self-care at all levels on SSI. CONCLUSION: The findings showed that the history of readmission and self-care at all levels is effective on SSI in the elderly with hip fractures. Therefore, it can be concluded that by identifying the factors affecting the SSI with hip fractures, fewer acute complications, reduced death and shorter length of hospital stay.

BACKGROUND: Omicron (B.1.1.529) is the fifth variant of concern of SARS-CoV-2, which has several subvariants. Clinical features of BA.1 and BA.2 infections have been described in the literature, but we have limited information about the clinical profile of BA.5, which caused the seventh wave in Iran. METHODS: A prospective observational study was conducted on the BA.5 confirmed patients referred to Imam Khomeini Hospital Complex, Tehran, Iran, from 11th to 31st August 2022. The patients were divided into the two groups of outpatients and hospitalized patients, and their clinical, radiological, and laboratory data and outcomes were recorded and analyzed. RESULTS: We included 193 patients with confirmed BA.5 infection, of whom 48 patients (24·8%) were hospitalized. The mean age of the patients was 45·3 ± 16·5 years, and 113 patients (58·5%) were female. The mean number of days patients had symptoms was 6·8 ± 2·4 days. The most common symptoms were weakness (69·9%), sore throat (67·4%), myalgia (66·3%), hoarseness (63·7%), headache (55·4%), fatigue (54·9%), and dry cough (50·3%). Fever and dyspnea were significantly more observed in the hospitalized patients (p < 0·0001). The COVID-19 vaccination rate was significantly lower in hospitalized patients than in outpatients (35/48-72·9% vs. 140/145 - 96·6%, p < 0·0001). The most common underlying diseases were hypertension (16·1%), diabetes mellitus (9·8%), and cardiovascular diseases (9·8%), all of which were significantly more common in hospitalized patients. Lung opacities were observed in 81·2% of hospitalized patients. By the end of our study, 1·5% of patients died despite receiving critical care services. CONCLUSIONS: Our findings suggested that BA.5 symptoms are more non-respiratory and usually improve within 7 days. Although the proportion of hospitalized patients is still significant, very few patients require intensive care. COVID-19 vaccination is effective in reducing the hospitalization rate. TRIAL REGISTRATION: Not applicable. This study is not a clinical trial.

WHAT IS KNOWN AND OBJECTIVE: Although antibiotics are ineffective against viral infections, epidemiological studies have revealed that the COVID-19 pandemic resulted in the overuse of antibiotics and disruption of antimicrobial stewardship programmes. We investigated the pattern of antibiotic use during the first 6 months of the COVID-19 pandemic in Iran. METHODS: A multi-centre retrospective study was designed to investigate the use of 16 broad-spectrum antibiotics in 12 medical centres. The rate of antibiotic use was calculated and reported based on the Defined Daily Dose (DDD) per 100 hospital bed-days. The bacterial co-infection rate was also reported. RESULTS AND DISCUSSION: Totally, 43,791 hospitalized COVID-19 patients were recruited in this study. It was found that 121.6 DDD of antibiotics were used per 100 hospital bed-days, which estimated that each patient received approximately 1.21 DDDs of antibiotics every day. However, the bacterial co-infections were detected only in 14.4% of the cases. A direct correlation was observed between the rate of antibiotic use and mortality (r[142] = 0.237, p = 0.004). The rate of antibiotic consumption was not significantly different between the ICU and non-ICU settings (p = 0.15). WHAT IS NEW AND CONCLUSION: In this study, widespread antibiotic use was detected in the absence of the confirmed bacterial coinfection in COVID-19 patients. This over-consumption of broad-spectrum antibiotics may be associated with increased mortality in hospitalized COVID-19 patients, which can be an alarming finding.

BACKGROUND: In this study, we assessed the prevalence of positive rapid detection test (RDT) among healthcare workers (HCWs) and evaluated the role of personal protective equipment (PPE) and knowledge of the pandemic. METHODS: In a cross-sectional study conducted between August 2020 and October 2020 in a tertiary referral center (Tehran, Iran), we enrolled 117 physicians, nurses, and other HCWs (OHCWs)-aides, helpers, and medical waste handlers-regularly working in coronavirus disease 2019 (COVID-19) wards. The RDT kit was utilized to reveal recent infection; data on demographics, PPE use and availability, and knowledge of the pandemic was collected through pre-defined questionnaires. RESULTS: Overall, 24.8% (95% CI: 16.8-32.7%) of HCWs had positive RDTs. The more PPE was available and used, the less the chance of positive RDT was (OR: 0.63 [0.44-0.91], P = 0.014 and 0.63 [0.41-0.96], P = 0.030). The same was true for the knowledge of prevention and adhering to preventive rules (OR: 0.44 [0.24-0.81], P = 0.008 and 0.47 [0.25-0.89], P = 0.020). OHCWs had the highest prevalence of positive RDT, while they had more shifts per month, less accessibility to PPE, and less knowledge of the pandemic than physicians. CONCLUSION: The findings of this study suggest that HCWs should have a thorough knowledge of the pandemic along with using PPE properly and rationally. Furthermore, adhering to preventive regulations plays a crucial role in HCWs' safety. It is also noteworthy that shifts should be arranged logically to manage exposures, with a special attention being paid to OHCWs.

Objectives: Osteoporosis is the most common metabolic bone disease. It is considered the silent epidemic, with high prevalence after menopause, in the current time. Different studies conducted in Iran have reported different prevalence. The present systematic review and meta-analysis aims to estimate the overall prevalence of osteoporosis in Iranian postmenopausal women. Methods: The national scientific databases Scientific Information Database and MagIran and the international scientific databases PubMed, Web of Science, and Scopus were searched for related articles without any time limitation. The keywords osteopenia, osteoporosis, post menopause, OP, bone mineral density, and Iran along with their combinations were used in the search. The inconsistency in the data was examined using I 2 test. The data were analyzed using the meta-analysis method and the random-effects model in Stata software, version 14. Results: The analysis of 26 articles with a sample size of 6735 showed that the prevalence of osteoporosis and osteopenia in Iranian postmenopausal women is, respectively, 33.70% (95% CI [confidence interval]: 22.68-44.73) and 47.60% (95% CI: 32.88-62.32). The pooled prevalence of osteoporosis in the spine and in the femur bone was 31.99% and 15.93%, respectively. Also, the prevalence of osteopenia in the spine and in the femur bone was 22.48% and 39.88%, respectively. Conclusion: Osteoporosis and osteopenia are highly prevalent in Iranian postmenopausal women to the extent that one-third of women suffer from osteoporosis and nearly half of them suffer from osteopenia. It seems essential to teach a healthy lifestyle to these women to reduce the prevalence of these issues.
RESUMEN
AIMS: COVID-19 is a significant global threat to public health. Despite the availability of vaccines and anti-viral drugs, there is an urgent need for alternative treatments to help prevent and/or manage COVID-19 symptoms and the underlying dysregulated immune response. We hypothesized that administration of Inflawell® syrup, a Boswellia extract formulation enriched for boswellic acids (BAs), can reduce the excessive or persistent inflammation and thereby prevent disease progression. BAs are medicinally activated triterpenoids found in the resins of Boswellia spp., and possess an immense therapeutic potential due to their anti-inflammatory and immunoregulatory activities. We investigated the effect of Inflawell® syrup, on moderate COVID-19 patients along with the current standard of care treatment. METHODS: A randomized placebo-controlled double-blind clinical trial was conducted, following definitive confirmation of COVID-19. Forty-seven hospitalized patients with moderate COVID-19 were enrolled and received either the Inflawell® syrup or placebo. Clinical symptoms and markers of inflammation were evaluated at baseline and completion of the trial. RESULTS: Our clinical trial revealed an increase in the percentage of oxygen saturation level in patients that received the BAs compared to placebo (P < 0.0001). In addition, the average duration of hospitalization was significantly shorter in the BAs group compared with the placebo group (P < 0.04). Concomitantly, some improvement in the clinical symptoms including cough, dyspnea, myalgia, headache, and olfactory and gustatory dysfunction were detected in the BAs group. Hematologic findings showed a significant decrease in the percentage of neutrophils (P < 0.006) and neutrophil-to-lymphocyte ratio (NLR) levels (P < 0.003), associated with a significant increase in the percentage of lymphocytes in the BAs group compared with the placebo (P < 0.002). Additionally, a significant decrease in CRP, LDH, IL - 6 and TNF - α levels was detected in the BAs group. Following the intervention, fewer patients in the BAs group were PCR-positive for COVID-19 compared to placebo, though not statistically significant. CONCLUSION: Overall, the treatment with Inflawell® resulted in shorter hospital stay, alleviation of COVID-19 clinical symptoms and decline in the level of pro-inflammatory cytokines. TRIAL REGISTRATION: The trial has been registered in https://www.irct.ir with unique identifier: IRCT20170315033086N10 ( https://en.irct.ir/trial/51631 ). IRCT is a primary registry in the WHO registry network ( https://www.who.int/clinical-trials-registry-platform/network/primary-registries ).

BACKGROUND: Proper hand hygiene is the most important action in preventing healthcare-associated infections (HCAIs). In this study, the knowledge and perception of hand hygiene assessed among nurses as the most exposed personnel to patients. METHODS: In this analytical cross-sectional study, the nurses working in different wards of a collegiate tertiary hospital in Tehran were investigated by standardized WHO questionnaires. RESULTS: Of the 101 participating nurses 89 (88.1%) were females. 81 (80.2%) had received formal related training. The 69 respondents estimated the mean prevalence of HCAI to be 38.91% and 98 (97.1%) considered hand hygiene an effective prevention in this regard. 78 (77.3%) perceived hand hygiene as the center priority; 82, 83 and 79 of participants would think that good hand hygiene matters for their superiors, colleagues and patients, respectively. The practice of hand hygiene was stated to be difficult by 48 (47.5%) respondents. There was no significant difference in self-reporting of hand hygiene practice among nurses in age (P=0.68), the degree of education (P=0.574), work experience (P=0.64), nor their wards (P=0.131). There was a significant reverse relationship with the supposed difficulty level of doing hand hygiene (P=0.049). The mean score of the nurses' knowledge was 66.53 (±9.41) based on the answers to the questions of the knowledge questionnaire. CONCLUSION: Knowledge and perception of hand hygiene, as this study showed, might not to be satisfactory; therefore, planning to improve these indicators and regular monitoring using standard tools is necessary for all healthcare centers.
RESUMEN
BACKGROUND: Breast cancer is the most common type of cancer of women across the world, which can affect the quality of life in patients due to complications caused by the disease and related treatments. Various treatments have been designed for these patients to improve their life quality. This study aimed to estimate the mean score of health-related quality of life patients with breast cancer in Iran. METHODS: In this study, we searched the national and international databases of SID, MagIran, Google Scholar, ISI/Web of Science, PubMed and Scopus with no time limits using the keywords of "health-related quality of life", "health related quality of life", "quality of life", "breast neoplasm", "breast cancer", and "breast tumors". Data analysis was performed in STATA version 14 based on the heterogeneity state using random effects model. RESULTS: In this study, 15 articles with a sample size of 1883 were evaluated, and the mean global quality of life in patients was reported at 72.48 (95% CI: 64.94-79.82). In addition, the worst performance and symptoms were related to emotional functioning (56.70) (95% CI: 49.84-63.55) and financial difficulties (43.57) (95% CI: 31.47-55.67). CONCLUSION: According to the results of the present study, the Iranian patients with breast cancer had a moderate quality of life in most dimensions.

INTRODUCTION: Seasonal influenza is an annual common occurrence in cold seasons; but the COVID-19 pandemic is also currently ongoing. These two diseases can't be distinguished from their symptoms alone; therefore, the importance of preventing influenza by vaccination is more than ever. Due to the high exposure of hospital personnel, widespread influenza vaccination of these high-risk groups seems to be a necessity. This Study conducted to determine vaccination coverage in the personnel of four tertiary referral collegiate hospitals in 2019 and to further investigate individual obstacles for Influenza vaccination. METHODS: In this cross-sectional descriptive study, 637 personnel were selected randomly from distinctive hospitals in a list-wised. Ones vaccinated filled the side effects questionnaire and who not vaccinated filled the vaccination obstacles questionnaire. The study was approved by the ethics committee of Tehran University of Medical Sciences with this reference number: IR.TUMS.IKHC.REC.1398.218. RESULTS: The mean vaccination coverage was 29.4% and the coverage difference among centers was not statistically significant (p = 0.192). The following items had the most impact on personnel decision: confidence about one's immune system (p < 0.05), the experience of side effects from previous vaccinations (p = 0.011), attitude about vaccination in colleagues (p = 0.021) and work experience (p < 0.05). About 23% of vaccinated individuals reported side effects following vaccination and the most common side effect was mild cold symptoms with 12.3% prevalence. CONCLUSION: The results of the current study revealed that influenza vaccination coverage among HCWs is not satisfactory in Iran. Hospital authorities and infection control units should plan to remove the obstacles of influenza vaccination.

BACKGROUND AND OBJECTIVES: Antimicrobial resistance (AMR) is an increasing threat for efficient treatment of infections. Determining the epidemiology of healthcare-associated infections and causative agents in various hospital wards helps appropriate selection of antimicrobial agents. MATERIALS AND METHODS: This retrospective study was performed by analyzing antibiograms from March 2017 to March 2018 among patients admitted to the different wards of Imam Khomeini Hospital Complex in Tehran, Iran. RESULTS: Among 2440 hospital acquired infections, 59.3% were Gram-negative bacilli: E. coli (n = 469, 22.2%), K. pneumoniae (n = 457, 21.7%), Acinetobacter spp. (n = 282, 13.4%), P. aeruginosa (n = 139, 6.6%) and important Gram-positive bacteria were Enterococcus spp. (n = 216, 10.2%), S. aureus (n = 148, 7%), S. epidermidis (n = 118, 5.6). Generally, there was a high antimicrobial resistance in bacterial isolates in this study. Methicillin resistant Staphylococcus aureus (MRSA) was 56.3 % and MRSE 62.9 %. Vancomycin resistant enterococci (VRE) was 60.7%. K. pneumoniae-ESBL was 79.6% and its resistance to carbapenem was 38.4%. E. coli-ESBL was 42% and its resistance to carbapenems was 2.3%. P. aeruginosa resistance to ceftazidime was 74.4%, to fluroquinolones 63.3%, to aminoglycosides 64.8%, to piperacillin tazobactam 47.6% and to carbapenems 62.1%. Acinetobacter baumannii resistance to ceftazidime was 98.7%, to fluroquinolones 97%, to aminoglycosides 95.9%, to ampicillin sulbactam 84%, to carbapenems 96.4% and to colistin 4%. CONCLUSION: The study revealed an alarming rate of resistance to the commonly used antimicrobial agents used in treating HAIs. Also the relationship between AMR and some risk factors and thus taking steps towards controlling them have been shown.
RESUMEN
BACKGROUND: Possibility of reinfection with SARS-CoV-2 changes our view on herd immunity and vaccination and can impact worldwide quarantine policies. We performed real-time polymerase chain reaction (RT-PCR) follow-up studies on recovered patients to assess possible development of reinfections and re-positivity. METHODS: During a 6-month period, 202 PCR-confirmed recovering COVID-19 patients entered this study. Follow-up RT-PCR tests and symptom assessment were performed 1 month after the initial positive results. Patients who tested negative were tested again 1 and 3 months later. The serum IgG and IgM levels were measured in the last follow-up session. RESULTS: In the first two follow-up sessions, 82 patients continued their participation, of which four patients tested positive. In the second follow-up 44 patients participated, three of whom tested positive. None of the patients who tested positive in the first and second follow-up session were symptomatic. In the last session, 32 patients were tested and four patients were positive, three of them were mildly symptomatic and all of them were positive for IgG. CONCLUSIONS: A positive RT-PCR in a recovering patient may represent reinfection. While we did not have the resources to prove reinfection by genetic sequencing of the infective viruses, we believe presence of mild symptoms in the three patients who tested positive over 100 days after becoming asymptomatic, can be diagnosed as reinfection. The immune response developed during the first episode of infection (e.g., IgG or T-cell mediated responses that were not measured in our study) may have abated the symptoms of the reinfection, without providing complete protection.

BACKGROUND AND OBJECTIVES: Nosocomial infections (NIs) are an important cause of mortality and morbidity in intensive care units (ICU). Pneumonia is the most common serious manifestation of infection in Covid-19 patients. The aim of this study was to investigate the prevalence of pneumonia in Covid-19 patients admitted to the ICU. MATERIALS AND METHODS: In this cross-sectional study, 1240 Covid-19 patients admitted for more than 48 h in the ICUs of Imam Khomeini Complex Hospital (IKCH) in Tehran for seven months in 2020 were included in the study with initial diagnosis of Covid-19 (PCR test and chest imaging). Data were collected regarding severity of the illness, primary reason for ICU admission, presence of risk factors, presence of infection, length of ICU and hospital stay, microbial type and antibiotic resistance. In this study, the pattern of antibiotic resistance was determined using the disk difusion method. RESULTS: In this study, 289 (23.3%) out of 1320 patients experienced NIs. 221 (76.4%) out of 289 patients had underlying diseases and the most common of which were hypertension, diabetes and heart disease, respectively. 163 patients (56.4%) were RT-PCR COVID-19 positive and 200 patients (69%) died. The majority of patients with NIs (71%) were over 55 years old. The most common type of nosocomial infection (66%) was ventilator-associated pneumonia (VAE). The most common microorganisms that cause pneumonia were Acinetobacter baumannii, Klebsiella pneumoniae and Pseudomonas aeruginosa, respectively. CONCLUSION: Pneumonia infection is high in Covid-19 patients admitted to the ICU, it needs to be planned with the diagnosis and measures related to the control and prevention of this infection.
RESUMEN
BACKGROUND: We studied the clinical characteristics and outcomes of 905 hospitalized coronavirus disease 2019 (COVID-19) patients admitted to Imam Khomeini Hospital Complex (IKHC), Tehran, Iran. METHODS: COVID-19 patients were recruited based on clinical symptoms and patterns of computed tomography (CT) imaging between February 20 and March 19. All patients were tested for the presence of COVID-19 RNA. The Poisson regression model estimated the incidence rate ratio (IRR) for different parameters. RESULTS: The average age (± standard deviation) was 56.9 (±15.7) years and 61.77% were male. The most common symptoms were fever (93.59%), dry cough (79.78%), and dyspnea (75.69%). Only 43.76% of patients were positive for the RT-PCR COVID-19 test. Prevalence of lymphopenia was 42.9% and more than 90% had elevated lactate dehydrogenase (LDH) or C-reactive protein (CRP). About 11% were severe cases, and 13.7% died in the hospital. The median length of stay (LOS) was 3 days. We found higher risks of mortality in patients who were older than 70 years (IRR = 11.77, 95% CI 3.63-38.18), underwent mechanical ventilation (IRR = 7.36, 95% CI 5.06-10.7), were admitted to the intensive care unit (ICU) (IRR = 5.47, 95% CI 4.00-8.38), tested positive on the COVID-19 test (IRR = 2.80, 95% CI 1.64-3.55), and reported a history of comorbidity (IRR = 1.76, 95% CI 1.07-2.89) compared to their corresponding reference groups. Hydroxychloroquine therapy was not associated with mortality in our study. CONCLUSION: Older age, experiencing a severe form of the disease, and having a comorbidity were the most important prognostic factors for COVID-19 infection. Larger studies are needed to perform further subgroup analyses and verify high-risk groups.
