The modified Rajan's heart failure risk score predicts all-cause mortality in patients hospitalized for heart failure with reduced ejection fraction: a retrospective cohort study.

Background: The dimensionless Rajan's heart failure (R-hf) risk score was proposed to predict all-cause mortality in patients hospitalized with chronic heart failure (HF) and reduced ejection fraction (EF) (HFrEF). Purpose: To examine the association between the modified R-hf risk score and all-cause mortality in patients with HFrEF. Methods: Retrospective cohort study included adults hospitalized with HFrEF, as defined by clinical symptoms of HF with biplane EF less than 40% on transthoracic echocardiography, at a tertiary centre in Dalian, China, between 1 November 2015, and 31 October 2019. All patients were followed up until 31 October 2020. A modified R-hf risk score was calculated by substituting brain natriuretic peptide (BNP) for N-terminal prohormone of BNP (NT-proBNP) using EF× estimated glomerular filtration rate (eGFR)× haemoglobin (Hb))/BNP. The patients were stratified into tertiles according to the R-hf risk score. The measured outcome was all-cause mortality. The score performance was assessed using C-statistics. Results: A total of 840 patients were analyzed (70.2% males; mean age, 64±14 years; median (interquartile range) follow-up 37.0 (27.8) months). A lower modified R-hf risk score predicted a higher risk of all-cause mortality, independent of sex and age [1st tertile vs. 3rd tertile: adjusted hazard ratio (aHR), 3.46; 95% CI: 2.11-5.67; P<0.001]. Multivariate Cox regression analysis indicated that a lower modified R-hf risk score was associated with increased cumulative all-cause mortality [univariate: (1st tertile vs. 3rd tertile: aHR, 3.45; 95% CI: 2.11-5.65; P<0.001) and multivariate: (1st tertile vs. 3rd tertile: aHR 2.21, 95% CI: 1.29-3.79; P=0.004)]. The performance of the model, as reported by C-statistic was 0.67 (95% CI: 0.62-0.72). Conclusion: The modified R-hf risk score predicted all-cause mortality in patients hospitalized with HFrEF. Further validation of the modified R-hf risk score in other cohorts of patients with HFrEF is needed before clinical application.

Frequency of Dimethyl Fumarate-Induced Lymphopenia among Omani Patients with Multiple Sclerosis.

Objectives: Dimethyl fumarate (DMF) is known to cause lymphopenia when used to treat patients with multiple sclerosis (MS). However, research on DMF therapy in the Arab world, especially in Oman, is scarce. This study aimed to analyse the prevalence of lymphopenia among Omani patients with MS and their reasons for discontinuing DMF therapy. Methods: In this retrospective study, the medical records of Omani patients with MS who were treated using DMF at two tertiary hospitals in Muscat, Oman, from February 2017 to February 2023 were reviewed. Their demographic, clinical and laboratory data were retrieved and analysed. Absolute lymphocyte count values at baseline and at the last follow-up, as well as the reasons for discontinuing DMF therapy, were collected. Descriptive and inferential statistical techniques were used for data analysis. Binary-logistic regression analysis was used to identify the risk factors for DMF-induced lymphopenia. Results: A total of 64 Omani patients with MS were included in this study. The majority of the study participants (n = 40; 63%) were female. All included patients started DMF therapy at the mean age of 33 ± 7.7 years. After administration of DMF, 14 (21.9%) patients developed grades 1-3 of lymphopenia. The DMF therapy was discontinued for 23 (36.0%) patients, mainly in response to adverse events or confirmed pregnancy. Female gender was the only significant predictor of DMF-induced lymphopenia (P = 0.037). Conclusions: Most Omani patients with MS had mild lymphopenia (grades 1-2). Early adverse events and pregnancy were the main reasons provided for discontinuing DMF therapy.

Atomized Intranasal Ketorolac Versus Intravenous Ketorolac for the Treatment of Severe Renal Colic in the Emergency Department: A Double-Blind, Randomized Controlled Trial.

STUDY OBJECTIVE: Atomized intranasal (IN) drug administration offers an alternative to the intravenous (IV) route. We aimed to evaluate the analgesic efficacy of IN versus IV ketorolac in emergency department patients with acute renal colic. METHODS: We conducted a double-blind, randomized controlled trial on adult patients (aged 18 to 64 years) with severe renal colic and numerical rating scale pain ratings ≥7.0. They were randomly assigned (1:1) to receive single doses of either IN or IV ketorolac. Our main outcomes were differences in numerical rating scale reduction at 30 and 60 minutes. A 95% confidence interval (CI) was calculated for each mean difference, with a minimum clinically important difference set at 1.3 points. Secondary outcomes included treatment response, adverse events, rescue medications, and emergency department revisits. We analyzed using intention-to-treat. RESULTS: A total of 86 and 85 patients with similar baseline characteristics were allocated to the IV and IN groups, respectively. Mean numerical rating scale scores were 8.52 and 8.65 at baseline, 3.85 and 4.67 at 30 minutes, and 2.80 and 3.04 at 90 minutes, respectively. The mean numerical rating scale reduction differences between the IV and IN groups were 0.69 (95% CI -0.08 to 1.48) at 30 minutes and 0.10 (95% CI -0.85 to 1.04) at 60 minutes. There were no differences in secondary outcomes. CONCLUSION: Neither IN or IV ketorolac was superior to the other for the treatment of acute renal colic, and both provided clinically meaningful reductions in pain scores at 30 to 60 minutes.

Morbidity and mortality of acute heart failure patients stratified by mitral regurgitation in the Arabian Gulf: Observations from the Gulf acute heart failure registry (Gulf CARE).

This study aimed to evaluate the clinical outcomes of patients with acute heart failure (AHF) stratified by mitral regurgitation (MR) in the Arabian Gulf. Patients from the Gulf CARE registry were identified from 47 hospitals in seven Arabian Gulf countries (Yemen, Oman, Kuwait, Qatar, Bahrain, the United Arab Emirates, and Saudi Arabia) from February to November 2012. The cohort was stratified into two groups based on the presence of MR. Univariable and multivariable statistical analyses were performed. The population cohort included 5005 consecutive patients presenting with AHF, of whom 1491 (29.8 %) had concomitant MR. The mean age of patients with AHF and concomitant MR was 59.2 ± 14.9 years, and 63.1 % (n = 2886) were male. A total of 58.6 % (n = 2683) had heart failure (HF) with reduced ejection fraction (EF) (HFrEF), 21.0 % (n = 961) had HF with mildly reduced EF (HFmrEF), and 20.4 % (n = 932) had HF with preserved EF (HFpEF). Patients with MR had a lower haemoglobin (Hb) level (12.4 vs. 12.7 g/dL; p < 0.001), and a higher prevalence of left atrial enlargement (80.2 % vs. 55.1 %; p < 0.001), cardiogenic shock (9.7 % vs. 7.3 %; p = 0.006) and atrial fibrillation (7.6 % vs. 5.6 %; p = 0.006), and HFrEF (71.0 % vs. 52.6 %; P < 0.001). Multivariable analysis demonstrated that MR was independently associated with increased all-cause mortality at 1-year and 3-month HF rehospitalization [1-year all-cause mortality, adjusted odds ratio (aOR), 1.40; 95 % confidence interval (Cl): 1.13-1.74; p = 0.002; 3-month HF rehospitalization, aOR, 1.26; 95 % Cl: 1.06-1.49; p = 0.009]. In an Arabian Gulf cohort with AHF, concomitant MR was associated with an increased risk of 1-year mortality and 3-months HF rehospitalization.

The Outcome of Antibiotic Overuse before and during the COVID-19 Pandemic in a Tertiary Care Hospital in Oman.

Antimicrobial resistance (AMR), a serious global public health challenge, may have accelerated development during the COVID-19 pandemic because antibiotics were prescribed for COVID-19. This study aimed to assess antibiotics use before and during the pandemic and correlate the results with the rate of resistant microorganisms detected in hospitalized patients during the study period. This single-center study looked retrospectively at four years of data (2018-2021) from Royal Hospital, Muscat, which is the biggest hospital in Oman with approximately 60,000 hospital admissions yearly. The consumption rate of ceftriaxone, piperacillin tazobactam, meropenem, and vancomycin was presented as the antibiotic consumption index, the ratio of defined daily dose (DDD) per 100 bed days. Analyses were performed using the nonparametric test for trend across the study period. Correlation between antibiotic consumption indexes and the isolated microorganisms in the four-year study period was performed using Spearman's rank correlation coefficient. We compared data from the pre-COVID-19 to the COVID-19 period. Though more patients were admitted pre-COVID-19 (132,828 versus 119,191 during COVID-19), more antibiotics were consumed during the pandemic (7350 versus 7915); vancomycin and ceftriaxone had higher consumption during than before the pandemic (p-values 0.001 and 0.036, respectively). Vancomycin-resistant Enterococcus (VRE) and Candida auris were detected more during the COVID-19 period with p-values of 0.026 and 0.004, respectively. Carbapenem-resistant Enterobacterales (CRE), vancomycin-resistant Enterococcus spp., and C. auris were detected more often during the pandemic with p-values of 0.011, 0.002, and 0.03, respectively. Significant positive correlations between antibiotic consumption and drug-resistant isolates were noted. This study confirms that the overuse of antibiotics triggers the development of bacterial resistance; our results emphasize the importance of antibiotic control.

Identification of Asymptomatic Severe Acute Respiratory Syndrome Coronavirus 2 Infections Among Healthcare Workers at Sultan Qaboos University Hospital, Oman.

Objectives: This study aimed to describe the incidence and features of asymptomatic COVID-19 infections among healthcare workers (HCWs) at a tertiary hospital in Oman. Methods: This cross-sectional study was conducted between August 2020 and February 2021 among HCWs with no history of COVID-19 infection. An online questionnaire collected sociodemographic and clinical data. COVID-19 infection was diagnosed using nasopharyngeal/throat swabs, which were tested for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Analyses were performed using the Chi-squared test, Fisher's exact test or univariate ordinary least squares regression, as appropriate. Results: A total of 583 HCWs participated in the study, most of whom were female (56.6%), and the mean age was 35 ± 8 years. Only 9.6% (95% confidence interval [CI]: 7.3-12.3%) of the HCWs were at high exposure risk as they were directly involved in the care of COVID-19-infected patients. Overall, 4.1% (95% CI: 2.7-6.1%) of the HCWs screened positive for SARS-CoV-2, of which 20.8% developed symptoms within two weeks. The frequency of SARS-CoV-2 positivity among HCWs working in high-, intermediate-, low- and miscellaneous-risk areas was 1.8% (95% CI: <0.1-9.6%), 2.6% (95% CI: <0.1-6.5%), 5.3% (95% CI: 0.3-9.3%) and 4.8% (95% CI: <0.1-69.3%), respectively. Working in high-risk areas was associated with increased compliance with various infection control strategies (P <0.001). Conclusion: There was a greater frequency of SARS-CoV-2 positivity among HCWs working in low-risk areas, whereas HCWs who worked in high-risk areas were significantly more likely to report increased compliance with infection control strategies.

Development and Validation of R-hf Risk Score in Acute Heart Failure Patients in the Middle East.

Objectives: The Rajan's heart failure (R-hf) score was proposed to aid risk stratification in heart failure patients. The aim of this study was to validate R-hf risk score in patients with acute decompensated heart failure. Methods: R-hf risk score is derived from the product estimated glomerular filtration rate (mL/min), left ventricular ejection fraction (%), and hemoglobin levels (g/dL) divided by N-terminal pro-brain natriuretic peptide (pg/mL). This was a multinational, multicenter, prospective registry of heart failure from seven countries in the Middle East. Univariable and multivariable logistic regression was applied. Results: A total of 776 patients (mean age = 62.0±14.0 years, 62.4% males; mean left ventricular ejection fraction = 33.0±14.0%) were included. Of these, 459 (59.1%) presented with acute decompensated chronic heart failure. The R-hf risk score group (≤ 5) was marginally associated with a higher risk of all-cause cumulative mortality at three months (adjusted odds ratio (aOR) = 4.28; 95% CI: 0.90-20.30; p =0.067) and significantly at 12 months (aOR = 3.84; 95% CI: 1.23-12.00; p =0.021) when compared to those with the highest R score group (≥ 50). Conclusions: Lower R-hf risk scores are associated with increased risk of all-cause cumulative mortality at three and 12 months.

Association between Non-Steroidal Anti-Inflammatory Drug Use and Major Cardiovascular Outcomes in Patients with Acute Coronary Syndrome in the Arabian Gulf.

Objectives: Studies on the association between non-steroidal anti-inflammatory drugs (NSAIDs) and major adverse cardiovascular events (MACE) in the Arabian Gulf are scarce. The aim of this study was to evaluate the association between NSAIDs use and MACE in acute coronary syndrome (ACS) patients in the Arabian Gulf region. Methods: Data were analyzed from 3007 consecutive patients diagnosed with ACS admitted to 29 hospitals in four Arabian Gulf countries from January 2012 to January 2013, as well as being on prior NSAIDs use during the index admission. The MACE included stroke/transient ischemic attacks (TIAs), myocardial infarction (MI), all-cause mortality and readmissions for cardiac reasons. Results: The overall mean age of the cohort was 62 ± 12 years, and 9.6% (n = 290) of the patients were on prior NSAID use during the index admission. At 12-months follow-up, after adjusting for confounding factors, patients on NSAIDs were significantly more likely to have had MACE (adjusted OR (aOR), 1.89; 95% confidence interval (CI): 1.44-2.48; p < 0.001). Specifically, the higher event rates observed were stroke/TIA (aOR, 2.50; 95% CI: 1.51-4.14; p < 0.001) and readmissions for cardiac reasons (aOR, 2.09; 95% CI: 1.59-2.74; p < 0.001), but not MI (aOR, 1.26; 95% CI: 0.80-1.99; p = 0.320) and all-cause mortality (aOR, 0.79; 95% CI: 0.46-1.34; p = 0.383). Conclusions: NSAIDs use was associated with significant stroke/TIA events as well as readmissions for cardiac reasons. However, NSAIDs were not associated with increased MIs or all-cause mortality rates in patients with ACS in the Arabian Gulf.

The Stability of Analytes of Ionized Magnesium Concentration and Its Reference Range in Healthy Volunteers.

This study aimed to determine the stability of refrigerated analytes of iMg concentration at different time intervals and to establish iMg reference range in a cohort of healthy Omani volunteers (≥18 years). The concentrations of iMg were measured using the direct ion-selective electrode technique. Pearson's and Lin's concordance correlation coefficients along with the Bland-Altman plot were used to assess the levels of agreement between iMg concentrations of fresh and refrigerated blood samples at different time intervals. The study included 167 volunteers (51% females) with a median age of 21 (range: 20-25) years. The median, 2.5th, and 97.5th percentiles for fresh iMg reference ranges were 0.55, 0.47, and 0.68 mmol/L, respectively. The overall agreement between the fresh and refrigerated iMg concentrations was poor (rho-c = 0.51; p < 0.001). However, according to Altman's definition, iMg concentrations of the refrigerated samples for a period of ≤1 h had an excellent correlation with the fresh iMg concentrations (Lin's rho-c = 0.80), with a small average bias difference of 0.009 (95%CI; -0.025-0.043). A cut-off refrigeration period within ≤1 h at 2-8 °C can be considered an alternate time frame for the gold standard measurement (fresh or within 0.5 h).

Predictors of Hypersensitivity Reactions to Platinum-Based Chemotherapy in a Tertiary Care Hospital in Oman: A case control study.

Objectives: This study aimed to estimate the prevalence and evaluate risk factors of hypersensitivity reactions (HSRs) to platinum-based compounds (PBCs) in cancer patients. PBCs play an important role in cancer therapy. However, one of the drawbacks of PBCs is the occasional occurrence of HSRs, which can lead to serious consequences. Methods: This retrospective case control study was conducted from January 2013 to December 2020 at Sultan Qaboos University Hospital, Muscat, Oman and included patients who received any PBC for the management of non-haematological cancers. Data regarding demographic characteristics and diseases and treatment details were collected from the hospital's electronic database. The data were quantitatively described and Student's t-test and Wilcoxon Mann-Whitney tests were used to detect significant differences. Results: A total of 38 cases and 148 matched controls were studied. The prevalence of HSRs to PBCs in the cohort of this study was 4.7% (95% confidence interval: 3.33-6.37%), higher with carboplatin compared with cisplatin and oxaliplatin. The female gender (P = 0.032), concomitant taxanes (P = 0.002) and concurrent radiation (P <0.001) were significant predictors of HSRs to PBCs. The majority of the reactions were of mild to moderate severity, and the rechallenge rate after HSR development was 13%. Conclusion: HSRs to PBCs impact therapy decisions and understanding the risk factors is important to improve treatment outcomes in cancer patients.

Access- and non-access-related infections among patients receiving haemodialysis: Experience of an academic centre in Oman.

Objective: The aim of this study was to examine the epidemiology of access and non-access-related infections in patients receiving haemodialysis at an academic tertiary hospital in Oman. Methods: This was a retrospective observational study of 287 hospitalized patients who received haemodialysis during the period January 2018 to December 2019 at Sultan Qaboos University Hospital, Muscat, Oman. Results: A total of 202 different infections were documented in 142 of the 287 patients (49.5%). Pneumonia was the most common infection in the patients examined, accounting for 24.8% (50/202) of the total infections. This was followed by bloodstream infections, with a prevalence of 19.8% (40/202). Klebsiella pneumoniae was the most prevalent isolate (19.0%; 47/248). The highest number of multidrug-resistant infections were caused by multidrug-resistant K. pneumoniae (29.9%; 23/77). Conclusions: Infections in patients undergoing haemodialysis are common and are dominated by non-access-related infections. Pneumonia was found to be the most prevalent infection in this population. Gram-negative bacteria, predominantly K. pneumoniae, were the most prevalent isolates. The study reported an alarming number of multidrug-resistant organisms, accounting for 31.0% of the total bacterial isolates from various clinical specimens.

Potentially Harmful Drug-Drug Interactions and Their Associated Factors Among Hospitalized Cardiac Patients: A Cross-Sectional Study.

BACKGROUND: Cardiovascular diseases are responsible for a significant proportion of mortalities worldwide. Elderly patients are the most affected by cardiovascular diseases, and because of factors such as polypharmacy, multimorbidity, and age-related changes in drug availability and metabolism, they are highly susceptible to the occurrence of drug-drug interactions. Drug-drug interactions are among the many drug-related problems leading to negative outcomes among inpatients and outpatients. Thus, it is important to investigate the prevalence, involved drugs, and factors related to potential drug-drug interactions (pDDIs) to properly optimize pharmacotherapy regimens for these patients. OBJECTIVE: We aimed to determine the prevalence of pDDIs, drugs most frequently implicated, and significant predictors associated with these interactions among hospitalized patients in the Cardiology Unit at Sultan Qaboos University Hospital in Muscat, Oman. METHODS: This retrospective cross-sectional study included 215 patients. Micromedex Drug-Reax® was used to identify pDDIs. Data extracted from patients' medical records were collected and analyzed. Univariable and multivariable linear regression was applied to determine the predictors associated with the observed pDDIs. RESULTS: A total of 2057 pDDIs were identified, with a median of nine (5-12) pDDIs per patient. Patients with at least one pDDI accounted for 97.2% of all the included patients. The majority of pDDIs were of major severity (52.6%), fair level of documentation (45.5%), and pharmacodynamic basis (55.9%). Potential drug-drug interactions between atorvastatin and clopidogrel were the most frequently observed (9%). Of all the detected pDDIs, around 79.6% of them included at least one antiplatelet drug. Having diabetes mellitus as a comorbidity (B = 2.564, p < 0.001) and the number of drugs taken during the hospitalization period (B = 0.562, p < 0.001) were factors positively associated with the frequency of pDDIs. CONCLUSIONS: Potential drug-drug interactions were highly prevalent among hospitalized cardiac patients at Sultan Qaboos University Hospital, Muscat, Oman. Patients having diabetes as a comorbidity and with a high number of administered drugs were at a higher risk of an increased number of pDDIs.

The Prevalence and Impact of Evidence-Based Medications on Cardiovascular and Cerebrovascular Outcomes in Patients with Acute Coronary Syndrome Post-Revascularization in Oman.

OBJECTIVES: International cardiovascular guidelines recommend prescribing a combination of five evidence-based medications (EBM) for acute coronary syndrome (ACS) patients post-revascularization. This study aims to assess the prevalence and impact of prescribing the full (five medications) versus partial (four medications or fewer) EBM combination on major adverse cardiovascular and cerebrovascular events (MACCE) in patients with ACS post-revascularization. METHODS: Data from patients with ACS who had revascularization between January 2016 and September 2021 were collected retrospectively. Patients were then followed up until March 2022 for MACCE. RESULTS: The full EBM combination was prescribed to 70% of the patients. However, after taking into account the presence of contraindications and clinical factors, the actual adherence to the guidelines was 95%. Patients who received the full EBM combination were younger (58 versus 62 years; p = 0.0 and 3) and had lower rates of chronic kidney disease (11% versus 41%; p < 0.001) and heart failure (9% versus 20%; p = 0.012) when compared to patients who received the partial EBM. Compared to the partial EBM group, the full EBM group was associated with lower MACCE rates (54% versus 37%, p = 0.012). After employing the propensity score technique utilizing the 1:1 nearest neighbor matching method without replacement, the univariate findings were further re-affirmed with those on full EBMs (compared to those on partial EBMs) associated with a significant reduction in the MACCE rate (average treatment effect of -25%; 95% confidence interval: -10--40%; p = 0.001). CONCLUSIONS: The full EBM utilization was significantly high in our setting and in line with international guidelines. The full EBM combination was predominantly prescribed in younger and less comorbid patients and was associated with lower MACCE rates. The findings were further reaffirmed by the propensity score matching method.

Early Prone versus Supine Positioning in Moderate to Severe Coronavirus Disease 2019 Patients with Acute Respiratory Distress Syndrome.

Objectives: This study sought to determine whether early prone positioning of patients with moderate to severe COVID-19-related acute respiratory distress syndrome (ARDS) lowers the mortality rate. Methods: We conducted a retrospective study using data from intensive care units of two tertiary centers in Oman. Adult patients with moderate to severe COVID-19-related ARDS with a PaO2/FiO2 ratio < 150 on FiO2 of 60% or more and a positive end-expiratory pressure of at least 8 cm H2O who were admitted between 1 May 2020 and 31 October 2020 were selected as participants. All patients were intubated and subjected to mechanical ventilation within 48 hours of admission and placed in either prone or supine position. Mortality was measured and compared between the patients from the two groups. Results: A total of 235 patients were included (120 in the prone group and 115 in the supine group). There were no significant differences in mortality (48.3% vs. 47.8%; p =0.938) and discharge rates (50.8% vs. 51.3%; p =0.942) between the prone and supine groups, respectively. Conclusions: Early prone positioning of patients with COVID-19-related ARDS does not result in a significant reduction in mortality.

Patients' knowledge and awareness of safe handling of oral anticancer agents at Sultan Qaboos University Hospital in Oman.

BACKGROUND: Safe handling of oral anticancer agents is of great concern. There is a lack of clear, national guidelines on how patients can safely handle and dispose of unwanted medications. We aimed to evaluate the safe handling, storage, and disposal of oral anticancer drugs among cancer patients and caregivers at home. METHOD: This cross-sectional survey of adult cancer patients (or their adult caregivers) used a closed-ended questionnaire from May 2019 to March 2020. RESULTS: A total of 257 patients (50 ± 15 years; range: 18-93 years) were enrolled; however, only 91% (233/257) reported self-administering oral anticancer medications. Caregivers were more likely to administer oral anticancer agents for patients ≥60 years than those <40 years old (63% vs. 8%; P = 0.001). Most patients (52%; 133/257) did not wash their hands after administering the drug; 74% (164/222) of the respondents reported that their medications were kept in a bedroom cabinet, while 18% (40/222) stored their medications in a refrigerator, and 5% (12/222) in a kitchen cabinet. A total of 55% (68/124) of patients returned their excess oral chemotherapy medications to the hospitals; however, 36% (45/124) disposed of their unused oral chemotherapy drugs in a household garbage container. CONCLUSION: While two-thirds of patients stored their oral anticancer medications properly, more than half used inappropriate handling procedures. Disposal practices were inconsistent and did not adhere to the reported international guidelines.

Impact of Clinical Pharmacists-driven Bundled Activities from Admission to Discharge on 90-day Hospital Readmissions and Emergency Department Visits.

Objectives: Patient-centered clinical pharmacists' activities play a major role in improving clinical outcomes by optimizing the efficacy of drug therapies and minimizing associated toxicities during hospitalization, at the transition of care, and upon discharge. We aimed to compare the impact of comprehensive versus partial clinical pharmacists-driven bundled of care services on the rate of 90-day hospital readmissions and emergency department (ED) visits. Methods: This retrospective study included all admitted patients who received a comprehensive or partial bundle of clinical pharmacy services (medication history, interventions, counseling, and discharge prescription review) from 1 January 2021 to 30 June 2021 at Sultan Qaboos University Hospital. The comprehensive bundle of care included the four services, while the partial bundle of care included one, two, or three services only. Analyses were performed using univariate and multivariate statistical techniques. Results: The study included 430 patients with a mean age of 56.021.0 years, and 43.7% (n = 188) were male. Of the patients, 12.1% (n = 52) received a comprehensive bundle of care. Compared with the partial bundle of care group, the comprehensive bundle of care group had significantly more patients with diabetes (65.4% vs. 42.9%; p =0.002), % 3 comorbidities (50.0% vs. 29.4%; p =0.003), and polypharmacy (% 5 medications) (73.1% vs. 46.0%; p < 0.001). The comprehensive bundle of care group was significantly associated with a lower 90-day readmission rate (adjusted odds ratio (aOR) = 0.27, 95% CI: 0.90?"0.82; p =0.021) but not with ED visits (aOR = 0.57, 95% CI: 0.13?"2.57; p =0.461). Conclusions: This study demonstrated a significant reduction in the 90-day readmission rate for patients on a comprehensive bundle of care but not ED visits. These findings emphasize the importance of the comprehensive services provided by clinical pharmacists on the healthcare resources use and clinical outcomes.

Clinical Outcome and Risk Assessment in Hospitalized COVID-19 Patients with Elevated Transaminases and Acute Kidney Injury: A Single Center Study.

Objectives: Initial reports indicate a high incidence of abnormal aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels in patients with COVID-19 and possible association with acute kidney injury (AKI). We aimed to investigate clinical features of elevated transaminases on admission, its association with AKI, and outcomes in patients with COVID-19. Methods: A retrospective analysis of the registered data of hospitalized patients with laboratory-confirmed COVID-19 and assessment of the AST and ALT was performed. Multinomial logistic regression was used to determine factors associated with community-acquired AKI (CA-AKI) and hospital-acquired AKI (HA-AKI). Results: The subjects comprised 828 patients (mean age = 65.0±16.0 years; 51.4% male). Hypertension was present in 70.3% of patients, diabetes mellitus in 26.0%, and chronic kidney disease in 8.5%. In-hospital mortality was 21.0%. At admission, only 41.5% of patients had hypertransaminasemia. Patients with elevated transaminases at admission were younger, had higher levels of inflammatory markers and D-dimer, and poorer outcomes. The AKI incidence in the study population was 27.1%. Patients with hypertransaminasemia were more likely to develop AKI (33.5% vs. 23.3%, p = 0.003). Patients with predominantly elevated AST (compared to elevated ALT) were more likely to have adverse outcomes. Multinomial logistic regression found that hypertension, chronic kidney disease, elevated AST, and hematuria were associated with CA-AKI. Meanwhile, age > 65 years, hypertension, malignancy, elevated AST, and hematuria were predictors of HA-AKI. Conclusions: Elevated transaminases on admission were associated with AKI and poor outcomes. Patients with elevated AST were more likely to have adverse outcomes. Elevated AST on admission was associated with CA-AKI and was a predictor of HA-AKI.

Epidemiological and Clinical Characteristics of Patients with Dengue Fever in a Recent Outbreak in Oman: A Single Center Retrospective-cohort Study.

Objectives: Dengue fever (DF) is the most common arthropod-borne viral illness with significant public health implications that can cause severe clinical symptoms and possibly death. We sought to determine the epidemiological and clinical characteristics of patients presented with DF to the Royal Hospital in a recent outbreak in Oman. Methods: We conducted a retrospective cohort study between 1 January and 18 April 2022, at the Royal Hospital, Oman, including all patients who presented with febrile illness and laboratory-confirmed DF. Descriptive statistics were used to summarize the results. Results: The cohort included 58 patients with laboratory-confirmed DF, of whom 39 (67.2%) required admission. The overall mean age was 41.0±20.0 years. Over half (55.2%) were females and the majority (86.2%) were Omani citizens. Eighty-one percent of the patients were residents of Bawshar in Muscat governorate. Dengue virus 2 was the isolated serotype. Fever (98.3%), muscular aches and pains (55.2%), and headache (53.4%) were the most common symptoms on presentation. All patients except two had no travel history. The most common comorbidities were hypertension (29.3%) and diabetes mellitus (17.2%). Upon admission, the most prominent hematological and biochemical abnormalities were severe thrombocytopenia (31.0%) with platelet counts of < 50 000/mm3 and hepatic impairment (15.5%). Antibiotics were prescribed to 27.6% of the patients. All patients improved clinically, and no deaths were reported during the study period. Conclusions: Fever and thrombocytopenia were the commonest presentations of DF. Identification of factors linked to increased risk of hospitalization in patients with DF can assist in recognizing individuals who need close monitoring and intensive support.

The Impact of Demographic, Clinical Characteristics and the Various COVID-19 Variant Types on All-Cause Mortality: A Case-Series Retrospective Study.

(1) Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has rapidly evolved into a pandemic affecting virtually every country in the world. We evaluated the demographic, clinical, laboratory, and all-cause mortality of moderate and severe COVID-19 patients admitted to a tertiary care hospital in Oman during the different COVID-19 waves and variant types. (2) Methods: A case-series retrospective study was carried out between 12 March 2020 and 30 June 2022. All adults over the age of 18 with laboratory-confirmed COVID-19 were enrolled. Analyses were performed using univariate and multivariate statistics. (3) Results: A total of 1462 confirmed cases enrolled with the mean age of the cohort was 55 ± 17 years with significant differences among the groups (p = 0.006). A total of 63% and 80% of the patients were males and citizens of Oman, respectively. Patients infected with the Alpha COVID-19 variant type were more likely to have acute respiratory distress syndrome (ARDS) (p < 0.001), stay longer in the hospital (p < 0.001), and get admitted to the intensive care unit (ICU) (p < 0.001). At the same time, those who had the Omicron COVID-19 type were more likely to have renal impairment (p < 0.001) and less likely to be associated with non-invasive ventilation (NIV) (p = 0.001) compared with other COVID-19 variant types. The Delta (adjusted odds ratio (aOR), 1.8; 95% confidence interval (CI): 1.22−2.66; p = 0.003) and Omicron (aOR, 1.88; 95% CI: 1.09−3.22; p = 0.022) COVID-19 variant types were associated with higher all-cause mortality when compared to the initial COVID-19 variant. Old age (aOR, 1.05; 95% CI: 1.04−1.06; p < 0.001), the presence of respiratory disease (aOR, 1.58; 95% CI: 1.02−2.44; p = 0.04), ICU admission (aOR, 3.41; 95% CI: 2.16−5.39; p < 0.001), lower eGFR (aOR, 1.61; 95% CI: 1.17−2.23; p = 0.004), and ARDS (aOR, 5.75; 95% CI: 3.69−8.98; p < 0.001) were also associated with higher mortality while NIV requirements were associated with lower odds of dying (aOR, 0.65; 95% CI: 0.46−0.91; p = 0.012). (4) Conclusions: Alpha and Delta variants were associated with a longer hospital stay, need for intensive care, mechanical ventilation, and increased mortality. Old age, cardiac renal dysfunction were commonly associated with Omicron variants. Large-scale national studies to further assess the risk factors for mortality related to COVID-19 waves are warranted.

A Snapshot of Potentially Inappropriate Prescriptions upon Pediatric Discharge in Oman.

Background: Identifying and quantifying potentially inappropriate prescribing (PIP) practices remains a time-consuming and challenging task, particularly among the pediatric population. In recent years, several valuable tools have been developed and validated for assessing PIP. This study aimed to determine the prevalence of PIP and related risk factors in pediatric patients at a tertiary care hospital in Oman. Materials and Methods: A retrospective study was conducted by reviewing the medical records of pediatric patients (<18 years) from 1 October to 31 December 2019. Potentially inappropriate medication (PIM) and potential prescribing omission (PPO) were assessed using an internationally validated pediatric omission of prescriptions and inappropriate prescriptions (POPI) tool. Results: A total of 685 patients were included; 57.5% were male, and 30.5% had at least one comorbidity. Polypharmacy was identified in 70.2% of these patients, with a median of 2 (1−3) medications. PIM was observed in 20.4% of the cohort, with the highest in ENT-pulmonary disease (30.5%), followed by dermatological disorders (28.6%). PPO was identified in 6.9% of the patients with digestive and neuropsychiatric disorders, with the highest rate of 54% and 24%, respectively. Age (p = 0.006), number of medications (p = 0.034), and prescriber rank (p = 0.006) were identified as significant predictors of PIM, whereas age (p = 0.044) was the only significant predictor for PPO. Conclusions: The rates of PIM and PPO were high in this study population. In light of these findings, educational and interventional activities and programs are needed.
