Portable RT-PCR System: a Rapid and Scalable Diagnostic Tool for COVID-19 Testing.

Combating the ongoing coronavirus disease 2019 (COVID-19) pandemic demands accurate, rapid, and point-of-care testing with fast results to triage cases for isolation and treatment. The current testing relies on reverse transcriptase PCR (RT-PCR), which is routinely performed in well-equipped laboratories by trained professionals at specific locations. However, during busy periods, high numbers of samples queued for testing can delay the test results, impacting efforts to reduce the infection risk. Besides, the absence of well-established laboratories at remote sites and low-resourced environments can contribute to a silent spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). These reasons compel the need to accommodate point-of-care testing for COVID-19 that meets the ASSURED criteria (affordable, sensitive, specific, user-friendly, rapid and robust, equipment-free, and deliverable). This study assessed the agreement and accuracy of the portable Biomeme SARS-CoV-2 system against the gold standard tests. Nasopharyngeal and nasal swabs were used. Of the 192 samples tested using the Biomeme SARS-CoV-2 system, the results from 189 samples (98.4%) were in agreement with the reference standard-of-care RT-PCR testing for SARS-CoV-2. The portable system generated simultaneous results for nine samples in 80 min with high positive and negative percent agreements of 99.0% and 97.8%, respectively. We performed separate testing in a sealed glove box, offering complete biosafety containment. Thus, the Biomeme SARS-CoV-2 system can help decentralize COVID-19 testing and offer rapid test results for patients in remote and low-resourced settings.

Effect of Piperacillin-Tazobactam vs Meropenem on 30-Day Mortality for Patients With E coli or Klebsiella pneumoniae Bloodstream Infection and Ceftriaxone Resistance: A Randomized Clinical Trial.

Importance: Extended-spectrum ß-lactamases mediate resistance to third-generation cephalosporins (eg, ceftriaxone) in Escherichia coli and Klebsiella pneumoniae. Significant infections caused by these strains are usually treated with carbapenems, potentially selecting for carbapenem resistance. Piperacillin-tazobactam may be an effective "carbapenem-sparing" option to treat extended-spectrum ß-lactamase producers. Objectives: To determine whether definitive therapy with piperacillin-tazobactam is noninferior to meropenem (a carbapenem) in patients with bloodstream infection caused by ceftriaxone-nonsusceptible E coli or K pneumoniae. Design, Setting, and Participants: Noninferiority, parallel group, randomized clinical trial included hospitalized patients enrolled from 26 sites in 9 countries from February 2014 to July 2017. Adult patients were eligible if they had at least 1 positive blood culture with E coli or Klebsiella spp testing nonsusceptible to ceftriaxone but susceptible to piperacillin-tazobactam. Of 1646 patients screened, 391 were included in the study. Interventions: Patients were randomly assigned 1:1 to intravenous piperacillin-tazobactam, 4.5 g, every 6 hours (n = 188 participants) or meropenem, 1 g, every 8 hours (n = 191 participants) for a minimum of 4 days, up to a maximum of 14 days, with the total duration determined by the treating clinician. Main Outcomes and Measures: The primary outcome was all-cause mortality at 30 days after randomization. A noninferiority margin of 5% was used. Results: Among 379 patients (mean age, 66.5 years; 47.8% women) who were randomized appropriately, received at least 1 dose of study drug, and were included in the primary analysis population, 378 (99.7%) completed the trial and were assessed for the primary outcome. A total of 23 of 187 patients (12.3%) randomized to piperacillin-tazobactam met the primary outcome of mortality at 30 days compared with 7 of 191 (3.7%) randomized to meropenem (risk difference, 8.6% [1-sided 97.5% CI, -∞ to 14.5%]; P = .90 for noninferiority). Effects were consistent in an analysis of the per-protocol population. Nonfatal serious adverse events occurred in 5 of 188 patients (2.7%) in the piperacillin-tazobactam group and 3 of 191 (1.6%) in the meropenem group. Conclusions and relevance: Among patients with E coli or K pneumoniae bloodstream infection and ceftriaxone resistance, definitive treatment with piperacillin-tazobactam compared with meropenem did not result in a noninferior 30-day mortality. These findings do not support use of piperacillin-tazobactam in this setting.

Identified Transmission Dynamics of Middle East Respiratory Syndrome Coronavirus Infection During an Outbreak: Implications of an Overcrowded Emergency Department.

A total 130 cases of Middle East respiratory syndrome coronavirus were identified during a large hospital outbreak in Saudi Arabia; 87 patients and 43 healthcare workers. The majority (80%) of transmission was healthcare-acquired (HAI) infection, with 4 generations of HAI transmission. The emergency department was the main location of exposure.

Notes from the Field: Nosocomial Outbreak of Middle East Respiratory Syndrome in a Large Tertiary Care Hospital--Riyadh, Saudi Arabia, 2015.

Since the first diagnosis of Middle East respiratory syndrome (MERS) caused by the MERS coronavirus (MERS-CoV) in the Kingdom of Saudi Arabia in 2012, sporadic cases and clusters have occurred throughout the country (1). During June-August, 2015, a large MERS outbreak occurred at King Abulaziz Medical City, a 1,200-bed tertiary-care hospital that includes a 150-bed emergency department that registers 250,000 visits per year.

The Saudi Critical Care Society practice guidelines on the management of COVID-19 in the ICU: Therapy section.

BACKGROUND: The rapid increase in coronavirus disease 2019 (COVID-19) cases during the subsequent waves in Saudi Arabia and other countries prompted the Saudi Critical Care Society (SCCS) to put together a panel of experts to issue evidence-based recommendations for the management of COVID-19 in the intensive care unit (ICU). METHODS: The SCCS COVID-19 panel included 51 experts with expertise in critical care, respirology, infectious disease, epidemiology, emergency medicine, clinical pharmacy, nursing, respiratory therapy, methodology, and health policy. All members completed an electronic conflict of interest disclosure form. The panel addressed 9 questions that are related to the therapy of COVID-19 in the ICU. We identified relevant systematic reviews and clinical trials, then used the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach as well as the evidence-to-decision framework (EtD) to assess the quality of evidence and generate recommendations. RESULTS: The SCCS COVID-19 panel issued 12 recommendations on pharmacotherapeutic interventions (immunomodulators, antiviral agents, and anticoagulants) for severe and critical COVID-19, of which 3 were strong recommendations and 9 were weak recommendations. CONCLUSION: The SCCS COVID-19 panel used the GRADE approach to formulate recommendations on therapy for COVID-19 in the ICU. The EtD framework allows adaptation of these recommendations in different contexts. The SCCS guideline committee will update recommendations as new evidence becomes available.

A Vanishing Cardiac Mass.

The prevalence of extrapulmonary tuberculosis (TB) is very common in the Middle East; however, myocardial involvement is among the most infrequent manifestations of extrapulmonary TB. We present a young adult who was incidentally found to have a large right atrial tuberculoma, diagnosed by non-invasive cardiac imaging and effectively treated with standard first-line anti-TB treatment, steroids, and anticoagulation. This case is a classical presentation of nodular myocardial involvement of TB, highlighting advantages of advanced imaging, e.g., cardiac magnetic resonance (CMR) and multidisciplinary treatment.

Natural History and Clinical Course of Symptomatic and Asymptomatic COVID-19 Patients in the Kingdom of Saudi Arabia.

OBJECTIVES: To analyze symptomatic and asymptomatic COVID-19 patients in Saudi Arabia in terms of initial presentation, risk factors, laboratory findings, clinical outcomes and healthcare utilization. METHODS: All laboratory-confirmed reverse transcription-polymerase chain reaction positive COVID-19 patients who had been tested at three governmental hospitals in Saudi Arabia (two in Riyadh and one in Makkah) between March 8 and May 18, 2020 were included. Demographics, COVID-19 variables, clinical characteristics and healthcare utilization variables were extracted and combined, and a descriptive analysis was conducted. Symptomatic and asymptomatic (on presentation) patients' data were compared. RESULTS: Eighty percent of the patients were males (81.4% of symptomatic and 73.2% of asymptomatic patients, P = 0.02). Moreover, 47.6% and 38.4% of symptomatic and asymptomatic patients were aged 40-64 years, respectively. Fever, cough and breathing difficulties were frequent presenting symptoms. Overall, diabetes (16.4%), hypertension (11.7%), chronic respiratory disease (7.1%) were the most frequent comorbidities, with no differences between the two groups. Symptomatic patients had higher C-reactive protein levels (3.55 vs. 0.30 mg/L; P < 0.0001) and lower total lymphocytes (1.41 vs. 1.70; P = 0.02). ICU admission and mortality were 12.1% and 4.1% in symptomatic, compared to 6.0% and 2.9% in asymptomatic patients, respectively. CONCLUSION: In the studied COVID-19 cohort, symptomatic patients tended to be older, had higher C-reactive protein and more lymphopenia with worse outcome than asymptomatic patients. This granular analysis of COVID-19 cohorts enables identification of at-risk cohorts in future waves, optimizing development of patient pathways and public health interventions.

Outcome of Oncology Patients Infected With Coronavirus.

PURPOSE: This study investigated the features of oncology patients with confirmed Middle East respiratory syndrome (MERS) at the Ministry of National Guard Health Affairs-Riyadh during the outbreak of June 2015 to determine the clinical course and outcome of affected patients. METHODS: The patients' demographic information, cancer history, treatment pattern, information about MERS-coronavirus (CoV) infection, history of travel, clinical symptoms, test results, and outcome were collected and analyzed as part of a quality improvement project to improve the care and safety of our patients. Only patients with confirmed infection were included. RESULTS: A total of 19 patients were identified, with a median age of 66 years (range, 16-88 years), and 12 patients (63%) were males. The most common underlying disease was hematologic malignancies (47.4%), followed by colorectal cancer (21%) and lung cancer (15.8%). Hypertension and diabetes mellitus were the most common comorbidities (57.9% and 52.6%, respectively). Infection was diagnosed by nasopharyngeal swab in all patients. All patients contracted the infection during their hospitalization for other reasons. Sixteen patients (80%) were admitted to the intensive care unit; 13 patients (81%) had acute respiratory distress syndrome, 11 were intubated (68.75%), 9 had acute renal injury (56.25%), and 3 required dialysis (18.75%). Only 3 patients (15.8%) with early-stage cancers survived. Patients with hematologic malignancies and advanced solid tumors had a 100% case fatality rate. The majority of the causes of death were due to multi-organ failure and septic shock. CONCLUSION: MERS-CoV infection resulted in a high case fatality rate in patients with malignancy. Therefore, it is critical to implement effective primary preventive measures to avoid exposure of patients with cancer to the virus.

The Public's Awareness and Willingness to Undergo Plastic Surgery Procedures during the COVID-19 Pandemic.

BACKGROUND: In March 2020, the Saudi Ministry of Health implemented mitigation measures to control the Coronavirus Disease 2019 (COVID-19) pandemic, including media campaigns, a nationwide lockdown, and closures of plastic surgery clinics. The aim of this study was to explore the public's knowledge of COVID-19, their willingness to undergo cosmetic surgery during the pandemic, and the factors influencing their decisions. METHODS: An internet-based cross-sectional survey was conducted. We collected data on demographic information, knowledge about COVID-19, and willingness to undergo cosmetic procedures. Participants also completed the cosmetic procedure screening questionnaire to assess body dysmorphic disorder. RESULTS: The sample included a total of 1643 participants (women, n = 1002; 61%). A total of 613 (37.3%) participants were aged between 30 and 40 years. The majority (n = 1472; 89.6%) referred to official government accounts for information regarding COVID-19. Most participants (n = 1451; 88.3%) felt that the pandemic was serious, and 1387 (85%) said they would not leave home to undergo cosmetic procedures during the outbreak. Being women, the presence of body-image concerns, and higher cosmetic procedure screening questionnaire scores were associated with an increased willingness to undergo cosmetic procedures. CONCLUSIONS: This is the first study to explore the public's willingness to undergo cosmetic procedures during the COVID-19 pandemic. The public was well educated about the pandemic, via government actions. This was reflected in participants who wished to undergo a cosmetic plastic procedure; we identified factors associated with an increased willingness to undergo procedures, which may help design awareness initiatives.

Principles of Care for Patients with Liver Disease During the Coronavirus Disease 2019 (COVID-19) Pandemic: Position Statement of the Saudi Association for the Study of Liver Disease and Transplantation.

In December 2019, a novel coronavirus was identified in patients in Wuhan, China. The virus, subsequently named severe acute respiratory syndrome coronavirus-2, spread worldwide and the disease (coronavirus disease 2019 or COVID-19) was declared a global pandemic by the World Health Organization in March 2020. Older adults and individuals with comorbidities have been reported as being more vulnerable to COVID-19. Patients with chronic liver disease (CLD) have compromised immune function due to cirrhosis and are more susceptible to infection. However, it is unclear if patients with CLD are more vulnerable to COVID-19 and its complications than other populations. The high number of severe cases of COVID-19 has placed an unusual burden on health systems, compromising their capacity to provide the regular care that patients with CLD require. Hence, it is incredibly crucial at this juncture to provide a set of interim recommendations on the management of patients with CLD during the current COVID-19 outbreak.

Prevalence and predictors of anxiety among healthcare workers in Saudi Arabia during the COVID-19 pandemic.

BACKGROUND: During pandemics, healthcare workers (HCWs) may be prone to higher levels of anxiety than those of the general population. This study aimed to explore the anxiety levels among HCWs in Saudi Arabia during the COVID-19 pandemic and the predictors of increased anxiety levels. METHOD: HCW participants in this cross-section study were solicited by email from the database of registered practitioners of the Saudi Commission for Health Specialties between 15 May and 18 May 2020. Sociodemographic characteristics, work-related factors, and organization-related factors were collected. RESULTS: Four thousand nine hundred and twenty HCWs (3.4%) responded. Reported levels of anxiety were low anxiety (31.5%; n = 1552), medium (36.1%; n = 1778), and high (32.3%; n = 1590). Participants reporting high anxiety levels were more likely to be unmarried (OR = 1.32, 95% CI: 1.14-1.52); nurses (OR = 1.54, 95% 1.24-1.91); workers in radiology (OR = 1.52, 95% CI: 1.01-2.28); or respiratory therapists (OR = 2.28, 95% CI: 1.14-4.54). Social factors associated with high anxiety levels were: living with a person who is elderly (p = 0.01), has a chronic disease (p < 0.0001), has immune deficiency (p < 0.0001), or has a respiratory disease (p-value <0.0001). Organization-related factors associated with a high level of anxiety were: working in an organization that hosts COVID-19 patients and working with such patients (p-value <0.0001). CONCLUSION: Self-reported medium and high levels of anxiety were present in 68.5% of HCWs in the COVID-19 pandemic. This highlights the urgent need to identify high-risk individuals to offer psychological support and provide up to date information on the pandemic. These data should help policymakers drive initiatives forward to protect and prepare HCWs psychological wellbeing.

Early switch/early discharge opportunities for hospitalized patients with methicillin resistant Staphylococcus aureus complicated skin and soft tissue infections: Saudi Arabia and United Arab Emirates.

OBJECTIVES: To describe opportunities for early switch (ES) from intravenous (IV) to oral (PO) antibiotics and early discharge (ED) of patients hospitalized in the Kingdom of Saudi Arabia (KSA) and the United Arab Emirates (UAE) with methicillin-resistant Staphylococcus aureus (MRSA) complicated skin and soft tissue infections (cSSTIs). METHODS: This retrospective medical chart review study enrolled physicians from 16 KSA and UAE sites to collect data for 107 MRSA cSSTI patients. RESULTS: Actual length of MRSA-active treatment was 13.3±9.3 mean days in KSA and 11.2±3.9 mean days in UAE, with a mean of 11.8±9.3 days of MRSA-targeted IV therapy in KSA and 10.7±4.3 days in UAE. 12.5% in KSA met ES criteria and potentially could have discontinued IV therapy 4.0±2.9 days sooner; 44.0% in UAE could have discontinued 6.6±3.6 days sooner. Patients were hospitalized for a mean 28.6±45.0 days in KSA and 13.1±5.9 days in UAE. 25.0% in KSA and 48.0% in UAE met ED criteria and potentially could have been discharged 6.1±8.0 days earlier in KSA and 7.9±5.0 days earlier in UAE. CONCLUSIONS: A significant proportion of patients hospitalized for MRSA cSSTI could be eligible for ES or ED opportunities, resulting in potential for reductions in IV and bed days.

Managing Oncology Services During a Major Coronavirus Outbreak: Lessons From the Saudi Arabia Experience.

Outbreaks of infectious etiology, particularly those caused by a novel virus that has no known treatment or vaccine, may result in the interruption of medical care provided to patients with cancer and put them at risk for undertreatment in addition to the risk of being exposed to infection, a life-threatening event among patients with cancer. This article describes the approach used to manage patients with cancer during a large-scale Middle East respiratory syndrome-coronavirus hospital outbreak in Saudi Arabia to ensure continuity of care and minimize harm from treatment interruption or acquiring infection. The approach taken toward managing this high-risk situation (COVID-19) could be easily adopted by health care organizations and would be helpful to ensure readiness for the occurrence of future outbreaks of different infectious etiologies like those recent episodes of new coronavirus.

Enhancing azithromycin antibacterial activity by encapsulation in liposomes/liposomal-N-acetylcysteine formulations against resistant clinical strains of Escherichia coli.

E. coli is an Enterobacteriaceae that could develop resistance to various antibiotics and become a multi-drug resistant (MDR) bacterium. Options for treating MDR E. coli are limited and the pipeline is somewhat dry when it comes to antibiotics for MDR bacteria, so we aimed to explore more options to help in treating MDR E. coli. The purpose of this study is to examine the synergistic effect of a liposomal formulations of co-encapsulated azithromycin and N-acetylcysteine against E. coli. Liposomal azithromycin (LA) and liposomal azithromycin/N-acetylcysteine (LAN) were compared to free azithromycin. A broth dilution was used to measure the MIC and MBC of both formulations. The biofilm reduction activity, thermal stability measurements, stability studies, and cell toxicity analysis were performed. LA and LAN effectively reduced the MIC of E. coli SA10 strain, to 3 µg/ml and 2.5 µg/ml respectively. LAN at 1 × MIC recorded a 93.22% effectiveness in reducing an E. coli SA10 biofilm. The LA and LAN formulations were also structurally stable to 212 ± 2 °C and 198 ± 3 °C, respectively. In biological conditions, the formulations were largely stable in PBS conditions; however, they illustrated limited stability in sputum and plasma. We conclude that the formulation presented could be a promising therapy for E. coli resistance circumstances, providing the stability conditions have been enhanced.

Mycobacterium smegmatis causing a granulomatous cardiomediastinal mass.

Non-tuberculous mycobacterial species are uncommon human pathogens. They are divided into slow and rapid growing mycobacteria (RGM) with Mycobacterium smegmatis group as an uncommon pathogen among the RGM. A 19 years old male presented with a 1 month history of dyspnea, orthopnea, unintentional weight loss, palpitation, flu-like symptoms and dry cough. Physical examination revealed tachycardia, distended superficial chest veins with a decrease in breath sounds at the right lower lung with fine crepitations. CT of the chest showed a large anterior mediastinal mass infiltrating the pericardium and three chambers of the myocardium that was confirmed using echocardiography. Despite negative workup for tuberculosis, the patient was treated successfully using first-line anti-TB treatment, which was begun before the tissue culture grew M. smegmatis. To our knowledge, this is the first case in the literature of M. smegmatis infection mimicking cardiomediastinal tuberculoma, and RGM should be suspected in similar presentations with negative TB workup, even in an immunocompetent patient. This is also the first patient to be treated using only first-line anti-tuberculous treatment successfully in the literature.

Mycobacterium riyadhense as the opportunistic infection that lead to HIV diagnosis: A report of 2 cases and literature review.

Human immunodeficiency virus (HIV) infection usually presents with a wide range of manifestations. Although HIV patients are prone to pulmonary infections by opportunistic pathogens in the late stage of AIDS, manifesting the disease with pulmonary infections caused by Mycobacterium riyadhense (newly identified non-tuberculous mycobacteria) is extremely rare with only one case reported in the literature. We are describing two previously healthy patients who presented with M. riyadhense lung infection and were subsequently found to have HIV, illustrating the need for considering the possibility M. riyadhense lung infection as a presenting illness of HIV.

Burden and treatment patterns of invasive fungal infections in hospitalized patients in the Middle East: real-world data from Saudi Arabia and Lebanon.

OBJECTIVES: The objective of this study was to document the burden and treatment patterns associated with invasive fungal infections (IFIs) due to Candida and Aspergillus species in Saudi Arabia and Lebanon. METHODS: A retrospective chart review study was conducted using data recorded from 2011 to 2012 from hospitals in Saudi Arabia and Lebanon. Patients were included if they had been discharged with a diagnosis of IFI due to Candida or Aspergillus, which was culture proven or suspected based on clinical criteria. Hospital data were abstracted for a random sample of patients to capture demographics, treatment patterns, hospital resource utilization, and clinical outcomes. Descriptive results were reported. RESULTS: Five hospitals participated and provided data on 102 patients with IFI (51 from Lebanon and 51 from Saudi Arabia). The mean age of the patients was 55 years, and 55% were males. Comorbidities included diabetes (41%), coronary artery disease (24%), leukemia (19%), moderate-to-severe renal disease (16%), congestive heart failure (15%), and chronic obstructive pulmonary disease (15%). Twenty percent of patients received corticosteroids prior to admission and 26% had received chemotherapy in the past 90 days. Inpatient mortality was 42%, and the mean hospital length of stay was 32.4±28.6 days. Fifty-five percent of patients required intensive care unit admission (17.2±14.1 days), 37% required mechanical ventilation (13.7±13.2 days), and 11% required dialysis (14.6±14.2 days). The most commonly used first-line antifungal was fluconazole. CONCLUSION: Patients with IFI in Saudi Arabia and Lebanon frequently have multiple medical comorbidities and may not have traditionally observed IFI risk factors. Efforts to increase use of rapid diagnostic tests and appropriate antifungal treatments may impact the substantial mortality and high length of stay observed in these patients.

Burden of methicillin-resistant Staphylococcus aureus pneumonia among hospitalized patients in Lebanon and Saudi Arabia.

OBJECTIVES: The objective of this study is to describe the real-world treatment patterns and burden of suspected or confirmed methicillin-resistant Staphylococcus aureus (MRSA) pneumonia in Saudi Arabia and Lebanon. METHODS: A retrospective chart review study evaluated 2011-2012 data from hospitals in Saudi Arabia and Lebanon. Patients were included if they had been discharged with a diagnosis of MRSA pneumonia, which was culture proven or suspected based on clinical criteria. Hospital data were abstracted for a random sample of patients to capture demographics (eg, age and comorbidities), treatment patterns (eg, timing and use of antimicrobials), hospital resource utilization (eg, length of stay), and clinical outcomes (eg, clinical status at discharge and mortality). Descriptive results were reported using frequencies or proportions for categorical variables and mean and standard deviation for continuous variables. RESULTS: Chart-level data were collected for 93 patients with MRSA pneumonia, 50 in Saudi Arabia and 43 in Lebanon. The average age of the patients was 56 years, and 60% were male. The most common comorbidities were diabetes (39%), congestive heart failure (30%), coronary artery disease (29%), and chronic obstructive pulmonary disease (28%). Patients most frequently had positive cultures from pulmonary (87%) and blood (27%) samples. All isolates were sensitive to vancomycin, teicoplanin, and linezolid, and only one-third of the isolates tested were sensitive to ciprofloxacin. Beta-lactams (inactive therapy for MRSA) were prescribed 21% of the time across all lines of therapy, with 42% of patients receiving first-line beta-lactams. Fifteen percent of patients did not receive any antibiotics that were considered to be MRSA active. The mean hospital length of stay was 32 days, and in-hospital mortality was 30%. CONCLUSION: The treatment for MRSA pneumonia in Saudi Arabia and Lebanon may be suboptimal with inactive therapy prescribed a substantial proportion of the time. The information gathered from this Middle East sample provides important perspectives on the current treatment patterns.

Epidemiology and outcome of invasive fungal infections and methicillin-resistant Staphylococcus aureus (MRSA) pneumonia and complicated skin and soft tissue infections (cSSTI) in Lebanon and Saudi Arabia.

The objectives of this retrospective medical chart review study were to document the inpatient incidence, treatment, and clinical outcomes associated with invasive fungal infections (IFI) due to Candida and Aspergillus species, Methicillin-resistant Staphylococcus aureus (MRSA) pneumonia and MRSA complicated skin and soft tissue infections (cSSTI) in the Middle East. This study evaluated 2011-2012 data from 5 hospitals in Saudi Arabia and Lebanon with a combined total of 207,498 discharges. Hospital medical chart data were abstracted for a random sample of patients with each infection type (102 patients - IFI, 93 patients - MRSA pneumonia, and 87 patients-MRSA cSSTI). Descriptive analysis found that incidence of IFI (per 1000 hospital discharges) was higher than MRSA cSSTI and MRSA pneumonia (IFI: 1.95 and 2.57; MRSA cSSTI: 2.01 and 0.48; and MRSA pneumonia 0.59 and 0.55 for Saudi Arabia and Lebanon, respectively). Median time from hospital admission to diagnosis and from admission to initiation of active therapy were 6 and 7 days, respectively, in IFI patients; median time from admission to diagnosis was 2days for both MRSA pneumonia and cSSTI, with a median of 4 and 2days from admission to MRSA-active antibiotic start, respectively. The mean hospital LOS was 32.4days for IFI, 32.4days for MRSA pneumonia and 26.3days for MRSA cSSTI. Inpatient mortality was higher for IFI (42%) and MRSA pneumonia (30%) than for MRSA cSSTI (8%). At discharge, 33% of patients with IFI and 27% and 9% of patients with MRSA pneumonia and cSSTI, respectively, were considered to have failed therapy. In conclusion, there is a significant burden of these serious infections in the Middle East, as well as opportunity for hospitals to improve the delivery of patient care for difficult-to-treat infections by promoting expedited diagnosis and initiation of appropriate antimicrobial therapy.

Treatment patterns, resource utilization, and outcomes among hospitalized patients with methicillin-resistant Staphylococcus aureus complicated skin and soft tissue infections in Lebanon and Saudi Arabia.

OBJECTIVES: To describe treatment patterns and medical resource use for methicillin-resistant Staphylococcus aureus (MRSA) complicated skin and soft tissue infections (cSSTI) in Saudi Arabia and Lebanon in terms of drug selection against the infecting pathogen as well as hospital resource utilization and clinical outcomes among patients with these infections. METHODS: This retrospective chart review study evaluated 2011-2012 data from five hospitals in Saudi Arabia and Lebanon. Patients were included if they had been discharged with a diagnosis of MRSA cSSTI, which was culture-proven or suspected based on clinical criteria. Hospital data were abstracted for a random sample of patients with each infection type to capture demographics, treatment patterns, hospital resource utilization, and clinical outcomes. Statistical analysis was descriptive. RESULTS: Data were abstracted from medical records of 87 patients with MRSA cSSTI; mean age 52.4±25.9 years and 61% male. Only 64% of patients received an MRSA active initial therapy, with 56% of first-line regimens containing older beta-lactams. The mean total length of stay was 26.3 days, with the majority (19.1 days) spent in general wards. Surgical procedures included incision and drainage (22% of patients), debridement (14%), and amputation (5%). Mechanical ventilation was required by 9% of patients, with a mean duration of 18 days per patient. Hemodialysis was required by four patients (5%), two of whom were reported to have moderate to severe renal disease on admission, for a mean of 5.5 days. Inpatient mortality was 8%. Thirty-nine percent were prescribed at least one antibiotic at discharge, with the most commonly prescribed discharge antibiotics being clindamycin (44%), ciprofloxacin (18%), trimethoprim/sulfamethoxazole (12%), and linezolid (9%). CONCLUSION: This Middle Eastern real-world study of resource use and treatment patterns in MRSA cSSTI indicates that management of this condition could be further optimized in terms of drug selection and resource utilization.
