Trends and Outcomes of Venous Thromboembolism in Hospitalized Patients With Ovarian Cancer: Results From Nationwide Inpatient Sample Database 2003 to 2011.

OBJECTIVE: Venous thromboembolism (VTE) is a major cause of mortality and morbidity in hospitalized patients with malignancy. Nationwide Inpatient Sample database was analyzed to determine the trends in the rate of hospitalization and mortality from VTE in hospitalized ovarian cancer patients and assess its economic impact and resource utilization. METHOD: We queried the 2003 to 2011 Nationwide Inpatient Sample database from Healthcare Cost and Utilization project (Agency of Healthcare Research and Quality) to identify all adults (age ≥18 years) ovarian cancer. Patients hospitalized with VTE as one of the top 3 discharge diagnoses were also identified. Demographic characteristics and in-hospital outcomes of this population were compared with ovarian cancer patients without VTE. Binary logistic regression analysis was used to obtain adjusted odds ratios (ORs). RESULTS: A total of 34,249 (3.5%) of a total of 981,386 hospitalized ovarian cancer patients had an accompanying diagnosis of VTE. Mean age of the study population was 64 years. After adjusting for potential confounders, compared with those without VTE, ovarian cancer patients with VTE had significantly higher inpatient mortality (6.2% vs 4.3%; OR, 1.12 [confidence interval (CI), 1.06-1.17]; P < .001), longer length of stay (5 vs 4 days; OR, 1.40 [CI, 1.36-1.43]; P < .001), higher average cost of hospitalization (US $26,000 vs US $22,000; OR, 1.10 [CI, 1.07-1.13]; P < .001), and greater disability at discharge (OR, 1.34 [CI, 1.31-1.38]; P < .001). Although the annual number of VTE admissions in ovarian cancer patients increased, in-hospital mortality declined from 10.9% in 2003 to 5.3% in 2011. CONCLUSIONS: Venous thromboembolism in hospitalized patients with ovarian cancer is associated with higher inpatient mortality, length of stay, higher cost of hospitalization, and disability at discharge. The hospitalization rate has increased, but the inpatient mortality rate has declined over study period.

Upward trend of dapsone-induced methemoglobinemia in renal transplant community
.

Dapsone, a sulfone antibiotic, is used for prophylaxis of Pneumocystis jirovecii pneumonia in patients with documented sulfa allergy. Acquired methemoglobinemia caused by dapsone is not uncommon in patients with normal glucose-6-phosphate dehydrogenase (G6PD) levels. Discrepancy between oxygen saturation measured by pulse oximetry and arterial oxygen saturation (SpO2) readings, a phenomenon known as "saturation gap," is noted with cases of methemoglobinemia. Although its prevalence in renal transplant patients is poorly described, there is evidence that its incidence is increasing. Here we describe a case series of 4 patients who were switched from trimethoprim-sulfamethoxazole (TMP-SMX) to dapsone and subsequently developed methemoglobinemia. Symptoms occur at varying methemoglobin levels and are more severe in patients with pre-existing coronary disease or chronic lung disease. Early recognition and cessation of dapsone is imperative, especially in renal transplant.

Anemia as a Significant Predictor of Adverse Outcomes in Hospitalized Patients With Acute Exacerbations of Chronic Obstructive Pulmonary Disease: Analysis of National (Nationwide) Inpatient Sample Database.

BACKGROUND: Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) has significant health implications. Anemia is usually an unseen comorbidity, which could significantly affect outcomes in AECOPD patients, and there is limited data to support this. We conducted this study to assess the effect of anemia on this patient population. METHODS: We performed a retrospective cohort study using the National (Nationwide) Inpatient Sample (NIS) data from 2008 to 2014. Patients with AECOPD and anemia with age >40 years were identified using appropriate International Classification of Diseases, Ninth Revision (ICD-9) codes, excluding transfer out to other hospitals. We calculated the Charlson Comorbidity Index as a measure of associated comorbidities. We analyzed bivariate group comparisons in patients with and without anemia. Odds ratios were calculated using multivariate logistic and linear regression analysis using SAS version 9.4 (2013; SAS Institute Inc. Cary, North Carolina, United States). RESULTS: Among 3,331,305 patients hospitalized with AECOPD, 567,982 (17.0%) had anemia as a comorbidity. The majority of patients were elderly, women, and white. After adjusting for potential confounders in regression, mortality (adjusted OR (aOR) 1.25, 95%CI: 1.18-1.32), length of hospital stay (ß 0.79, 95%Cl 0.76-0.82), and hospitalization cost (ß 6873, 95%Cl 6437-7308) were significantly higher in patients with anemia. In addition, patients with anemia required significantly higher blood transfusion (aOR 16.9, 95%CI 16.1-17.8), invasive ventilator support (aOR 1.72, 95%CI 1.64-1.79), and non-invasive ventilator support (aOR 1.21, 95%CI 1.17-1.26). CONCLUSION: In this first retrospective largest cohort study on this topic, we find anemia is a significant comorbidity associated with adverse outcomes and healthcare burden in hospitalized AECOPD patients. We should focus on close monitoring and management of anemia to improve the outcomes in this population.

A cohort study for derivation and validation of a clinical prediction scale for hospital-onset Clostridium difficile infection.

OBJECTIVE: To develop and validate a clinical prediction scale for hospital-onset Clostridium difficile infection (CDI). METHODS: A community-based, 360-bed hospital located in the suburbs of a metropolitan area in the United States served as the setting for the present retrospective cohort study. The cohort consisted of patients admitted to the adult medical service over a six-year period from October 2005 to September 2011. The cohort was divided into derivation (October 2005 to September 2009) and validation (October 2009 to September 2011) groups. The primary outcome measure was hospital-onset CDIs identified as stool positive for C difficile after 48 h of hospital admission ordered for new-onset unformed stool by the treating physician. RESULTS: In the derivation phase, 35,588 patients were admitted to the medical service and 21,541 stayed in hospital beyond 48 h. A total of 266 cases of CDI were identified, 121 of which were hospital onset. The developed clinical prediction scale included the onset of unformed stool (5 points), length of hospital stay beyond seven days (4 points), age >65 years (3 points), long-term care facility residence (2 points), high-risk antibiotic use (1 point) and hypoalbuminemia (1 point). The scale had an area under the receiver operating curve (AUC) of 0.93 (95% CI 0.82 to 0.94) in predicting hospital-onset CDI, with a sensitivity of 0.94 (95% CI 0.88 to 0.97) and a specificity of 0.80 (95% CI 0.79 to 0.80) at a cut-off score of 9 on the scale. During the validation phase, 16,477 patients were admitted, of whom 10,793 stayed beyond 48 h and 58 acquired CDI during hospitalization. The predictive performance of the score was maintained in the validation cohort (AUC 0.95 [95% CI 0.93 to 0.96]) and the goodness-to-fit model demonstrated good calibration. CONCLUSION: The authors developed and validated a simple clinical prediction scale for hospital-onset CDI. This score can be used for periodical evaluation of hospitalized patients for early initiation of contact precautions and empirical treatment once it is validated externally in a prospective manner.

Optimizing Discharge Summaries: A Multispecialty, Multicenter Survey of Primary Care Clinicians.

BACKGROUND: Patient care in the United States has become increasingly more fragmented, and the discharge summary serves as a critical tool for transmitting information on a patient's hospital admission to the primary care clinician. Some guidelines regarding how to write discharge summaries exist, but few are focused on prioritizing content that is most important to optimize a patient's transition of care. METHODS: We conducted a national survey across various medical primary care specialties, including trainees and advanced practice providers, to understand the priorities of primary care clinicians. We distributed the survey to 2184 clinicians affiliated with 8 large academic institutions. Our response rate was 21%. RESULTS: Hospital course, discharge diagnoses, medication reconciliation, and follow-up sections were ranked as the most important categories with a 95.5% concordance rate among surveyed institutions. The least important sections were contact numbers for inpatient clinicians, ancillary services, weight-bearing status, and wound care. Similar themes were also identified via consensus review of the free-texted comments, adding that discharge summary style was also important. Other identified barriers to high-quality transition of care are both the limited time primary care clinicians can spend reviewing discharge summaries and lack of adequate communication between hospitalists and the outpatient clinician. CONCLUSIONS: High-yield content should be presented at the beginning of the discharge summary and conveyed in a brief, succinct manner to ensure maximal utility of the document as a transition of care tool.

Comprehensive review of mask utility and challenges during the COVID-19 pandemic.

Masks are widely discussed during the course of the ongoing COVID-19 pandemic. Most hospitals have implemented universal masking for their healthcare workers, and the Center for Disease Control currently advises even the general public to wear cloth masks when outdoors. The pertinent need for masks arises from plausible dissemination of the SARS-CoV-2 through close contacts, as well as the possibility of virus transmission from asymptomatic, pre-symptomatic, and mildly symptomatic individuals. Given current global shortages in personal protective equipment, the efficacy of various types of masks: N95 respirators, surgical masks, and cloth masks are researched. To accommodate limited supplies, techniques for extended use, reuse, and sterilization of masks are strategized. However, masks alone may not greatly slow down the COVID-19 pandemic unless they are coupled with adequate social distancing, diligent hand hygiene, and other proven preventive measures.

COVID-19 disparity among racial and ethnic minorities in the US: A cross sectional analysis.

AIM: To analyze racial disparities in Coronavirus disease (COVID-19) cases in the United States of America and discuss possible reasons behind this inequality. SUBJECT AND METHODS: We obtained estimated case counts of African-American, Caucasian, Native American, Asian and Hispanic individuals with coronavirus disease (COVID-19)infection through May 5, 2020, from publicly available data on state departments of health websites. We calculated race-specific fractions as the percentage of the total population and analyzed the reasons behind this disparity. RESULTS: The incident rates of COVID-19 were higher among African Americans and among Latinos disproportionately higher than their representation in 14 states and 9 states, respectively. A similar observation was also reported for New York city. The percentage of deaths reported among African Americans was disproportionately higher than their represented share in the population in 23 out of 35 states. It was reported that 22.4% of COVID-19 deaths in the USA were African American, even though black people make up 13.4% of the USA population. CONCLUSIONS: The analysis shows the disparity of coronavirus disease outcomes by ethnicity and race. Additional research is needed to determine the factors behind this inequality.

Impact of hospitalists on the efficiency of inpatient care and patient satisfaction: a systematic review and meta-analysis.

Background: Over the past 20 years, hospitalists have assumed a greater portion of healthcare service for hospitalized patients. This was mainly due to reducing the length of stay (LOS) and hospital costs shown by many studies. In contrast, other studies suggested increased cost and resources utilization associated with hospitalist-run care models. Aim: We aimed to provide class 1 evidence regarding the effect of hospitalist-run care models on the efficiency of care and patient satisfaction. Design: Meta-analysis. Methods: Four electronic medical databases were searched to retrieve all relevant studies. Two authors screened titles and abstracts of search results for eligibility according to predefined criteria. Initially eligible studies were screened for full text inclusion. Included studies were reviewed for data on LOS, hospital cost, readmission, mortality, and patient satisfaction. Available data were abstracted and analyzed using Comprehensive Meta-Analysis. Results: Sixty-one studies were included for analysis. The overall effect size favored hospitalist-run care models in terms of LOS (MD = -0.67 day, 95% CI [-0.78, -0.56], p < 0.001). There was no significant difference in terms of hospital cost (MD = $92.1, 95% CI [-910.4, 1094.6], p = 0.86) whereas patient satisfaction was similar or even better in hospitalist compared to non-hospitalist (NH) service. Conclusion: Our analysis showed that hospitalist care is associated with decreased LOS and increased patient satisfaction compared to NH. This indicates an increase in the efficiency of care that does not come at the expense of care quality.

Era of hospitalists.

Hospitalists, known as physicians, are an emerging group in the medical field that is focused on the general medical care of hospitalized patients. Specializing in hospital medicine, they often attract a mix of appreciation and criticism. In the present manuscript, we review the pros and cons of a hospitalist in the health-care system. Although experts agree that hospitalists add value to the health-care system by reducing costs, streamlining administrative processes, and contributing to improved health-care outcomes, there is a large degree of disagreement regarding the extent of hospitalist contribution to overall improvements on health-care outcomes. In this paper, new strategies to overcome reported shortcomings and to further improve the quality of health care are discussed.

Bullosis Diabeticorum: A Rare Presentation with Immunoglobulin G (IgG) Deposition Related Vasculopathy. Case Report and Focused Review.

BACKGROUND Bullosis diabeticorum (BD) is a condition characterized by recurrent, spontaneous, and non-inflammatory blistering in patients with poorly controlled diabetes mellitus. While etiopathogenesis remains unclear, roles of neuropathy, vasculopathy and UV light are hypothesized. Most literature reports negative direct and indirect immunofluorescence findings in diabetics with bullous eruptions. Porphyria cutanea tarda, bullous pemphigoid, epidermolysis bullosa, and pseudoporphyria are other differential diagnoses of bullous lesions, and they must be excluded. CASE REPORT We present a 42-year-old African American male with long standing poorly controlled insulin dependent diabetes mellitus with blisters on his left hand and feet. The blisters were noticed three weeks prior to presentation and, thereafter, rapidly increased in size and spontaneously ruptured. Physical examination revealed a multitude of both roofed and unroofed bullous painless skin lesions. Hematoxylin and eosin (H&E) staining dramatized the dermal-epidermal blistering and re-epithelization process. Direct Immunofluorescence (DIF) was positive for 2 + IgG deposition in the already thickened basement membrane of the capillaries of the superficial vascular plexus. After debridement, his wounds greatly improved with over three months of aggressive wound care. CONCLUSIONS Primary immunologic abnormality likely plays no role in the onset of BD. To date, only one article has reported nonspecific capillary-associated immunoglobulin M and C3. This is the first case of BD with IgG deposition in the superficial capillary basement membrane. Positive findings on DIF suggest vasculopathy. Dermal microangiopathy, secondary to immunologic abnormality, is a possible underlying pathogenesis to bullae formation. Punch biopsy with DIF can be an additional diagnostic modality in the management of such cases.

Denosumab-Associated Severe Hypocalcemia in a Patient With Chronic Kidney Disease.

Denosumab is a monoclonal antibody directed against the receptor activator of nuclear factor kappa B ligand (RANKL). Denosumab has been shown to reduce the risk of skeletal-related events, including spinal cord compression, pathologic fracture and hypercalcemia of malignancy in patients with bone metastases. Hypocalcemia is a known side effect of denosumab, occurring in an estimated 8-14% of the patients. Here, we present an asymptomatic patient with stage-5 chronic kidney disease and severe hypocalcemia who had received denosumab 1 month earlier.

Non-ST elevation myocardial infarction secondary to carbon monoxide intoxication.

Carbon monoxide poisoning has been documented in literature to cause severe neurological and tissue toxicity within the body. However, cardiotoxicity is often overlooked, but not uncommon. Previous research studies and case reports have revealed a significant relationship between carbon monoxide intoxication and myocardial ischemic events. We report a case of a 48-year-old male, who was exposed to severe smoke inhalation due to a house fire and subsequently developed a non-ST elevation myocardial infarction. Ischemic changes were evident on electrocardiogram, which demonstrated T-wave inversion in lead III and ST-segment depression in leads V4-V6. Elevated cardiac enzymes were also present. After standard treatment for an acute cardiac event, the patient fully recovered. This case demonstrates that myocardial ischemic changes due to carbon monoxide poisoning may be reversible if recognized in early stages and treated appropriately, thus reminding physicians that a proper cardiovascular examination and diagnostic testing should be performed on all patients with carbon monoxide poisoning. Abbreviations: NSTEMI: Non-ST elevation myocardial infarction.

Nephrology key information for internists.

Hospitalists and primary care physicians encounter renal disease daily. Although most cases of acute kidney injury (AKI) are secondary to dehydration and resolve by giving fluids, many cases of AKI are due to not uncommon but unfamiliar causes needing nephrology evaluation. Common indications to consult a nephrologist on an emergency basis include hyperkalemia or volume overload in end stage renal disease patients (ESRD). Other causes of immediate consultation are cresenteric glomerulonephritis / rapidly progressive glomerulonephritis in which renal prognosis of the patient depends on timely intervention. The following evidence-based key information could improve patient care and outcomes. Abbreviations: AKI: Acute kidney injury ESRD: End stage renal disease patients.

Adoption of electronic health records and barriers.

Electronic health records (EHR) are not a new idea in the U.S. medical system, but surprisingly there has been very slow adoption of fully integrated EHR systems in practice in both primary care settings and within hospitals. For those who have invested in EHR, physicians report high levels of satisfaction and confidence in the reliability of their system. There is also consensus that EHR can improve patient care, promote safe practice, and enhance communication between patients and multiple providers, reducing the risk of error. As EHR implementation continues in hospitals, administrative and physician leadership must actively investigate all of the potential risks for medical error, system failure, and legal responsibility before moving forward. Ensuring that physicians are aware of their responsibilities in relation to their charting practices and the depth of information available within an EHR system is crucial for minimizing the risk of malpractice and lawsuit. Hospitals must commit to regular system upgrading and corresponding training for all users to reduce the risk of error and adverse events.

Transmission of vaccinia virus, possibly through sexual contact, to a woman at high risk for adverse complications.

Severe adverse events, including eczema vaccinatum (EV), can result after smallpox vaccination. Persons at risk for EV include those with underlying dermatologic conditions, such as atopic dermatitis. We investigated a case of vaccinia infection, possibly acquired during sexual contact with a recently vaccinated military service member, in a female Maryland resident with atopic dermatitis. The U.S. Department of Defense's Vaccine Healthcare Centers Network (VHCN) and the Centers for Disease Control and Prevention (CDC) worked in conjunction with the patient's physician and the Maryland Department of Health and Mental Hygiene (DHMH) to confirm the diagnosis, ensure treatment, and prevent further transmission. Specimens collected from the patient were tested at the DHMH laboratories and were positive by real-time polymerase chain reaction for nonvariola orthopoxvirus. Testing at the CDC verified the presence of vaccinia-specific DNA signatures. Continuing spread of the patient's lesions led to the administration of vaccinia immune globulin and strict infection control measures to prevent tertiary transmission to vulnerable family members, also with atopic dermatitis. VHCN contacted the service member to reinforce vaccination site care and hygiene. This case underscores the importance of prevaccination education for those receiving the smallpox vaccine to protect contacts at risk for developing severe adverse reactions.

Personal health care of internal medicine residents.

INTRODUCTION: Medical residents, as part of their job to balance the demands of their work with caring for themselves so as to be mentally, emotionally, and physically sound to stay clinically competent. While regulatory and legislative attempts at limiting medical resident work hours have materialized but have yet to attain passage, there are fairly little data looking into how residents cope up with their demands and yet attend to their own personal health. DESIGN: Anonymous mailed survey. SUBJECTS: Three hundred and thirty-seven residents from all internal medicine residency programs within United States. METHODS: We conducted a survey in the form of a questionnaire that was sent by e-mail to the program directors of various internal medicine residency programs within the United States, and responses were collected between May 19 and June 21, 2009. Response was well appreciated with total number of participants of 337 with even demographical distribution in gender, residency year, AMG/IMG, age group. Seventy-one percent of the residents felt that they would prefer getting admitted to their own hospital for any acute medical or surgical condition. Of the 216 residents who have had received health care in the past, almost half of them chose their own hospital because of the proximity, while 45% did not choose their own hospital despite proximity. Two out of three residents missed their doctors appointments or cancelled them due to demands of medical training. Only half of the residents have a primary care physician and almost 80% of them did not have their yearly health checkup. Close to 30% held back information regarding their social and sexual history from their provider because of privacy and confidentiality concerns. Eighty percent of residents never received information about barriers that physicians may face in obtaining care for their socially embarrassing conditions. Seventy percent felt that their performance then was suboptimal because of that health condition and also felt sick but did not drop the call. Half of the residents had concerns that they might be having a psychiatric illness, but only 5% of them received a formal evaluation at their own hospital and 23 (12.4%) at an outside hospital. CONCLUSIONS: It is very important to have more studies to emphasize on resident's physical and mental health and encourage them to have a primary care physician. There are several reasons preventing residents from getting a formal evaluation, confidentiality reasons, lack of time - schedule constraints, fear of being labeled, and social repercussions are few of them. Program directors should encourage the residents to not only care of the health of their patients but also be enthusiastic about their personal health issues for upgraded, revised patient care, and ultimately for their overall well-being.
