Reduced Cognitive Burden and Increased Focus: A Mixed-methods Study Exploring How Implementing Scribes Impacted Physicians.

BACKGROUND: Understanding how medical scribes impact care delivery can inform decision-makers who must balance the cost of hiring scribes with their contribution to alleviating clinician burden. OBJECTIVE: The objective of this study was to understand how scribes impacted provider efficiency and satisfaction. DESIGN: This was mixed-methods study. PARTICIPANTS: Internal and family medicine clinicians were included. MEASURES: We administered structured surveys and conducted unstructured interviews with clinicians who adopted scribes. We collected average days to close charts and quantity of after-hours clinical work in the 6 months before and after implementation using electronic health record data. We conducted a difference in difference (DID) analysis using a multilevel Poisson regression. RESULTS: Three themes emerged from the interviews: (1) charting time is less after training; (2) clinicians wanted to continue working with scribes; and (3) scribes did not reduce the overall inbox burden. In the 6-month survey, 76% of clinicians endorsed that working with a scribe improved work satisfaction versus 50% at 1 month. After implementation, days to chart closure decreased [DID=0.38 fewer days; 95% confidence interval (CI): -0.61, -0.15] the average minutes worked after hours on clinic days decreased (DID=-11.5 min/d; 95% CI: -13.1, -9.9) as did minutes worked on nonclinical days (DID=-24.9 min/d; 95% CI: -28.1, -21.7). CONCLUSIONS: Working with scribes was associated with reduced time to close charts and reduced time using the electronic health record, markers of efficiency. Increased satisfaction accrued once scribes had experience.

Histoplasma capsulatum Pacemaker-related Endocarditis Presenting as Endogenous Endophthalmitis.

PURPOSE: To report a unique case of pacemaker-related infective endocarditis manifesting as endogenous endophthalmitis with chorioretinitis secondary to Histoplasma capsulatum. METHOD: Case Report. RESULTS: A 75-year-old man was diagnosed with blood culture-negative infective endocarditis and was admitted with deteriorating vision and ocular inflammation. Examination of the eye indicated significant vitreous inflammation and retinitis. Vitreous cultures were negative, but universal fungal PCR of the vitreous fluid was positive for Histoplasma capsulatum. Histopathology of the fibrous cuff around the extracted right atrial lead demonstrated hyphal and yeast forms and PCR of this material identified Histoplasma capsulatum. Despite aggressive antifungal and surgical treatment, the eye became phthisical. CONCLUSION: We highlight the importance of considering Histoplasma capsulatum in the differential diagnosis of endogenous endophthalmitis, particularly among patients from endemic areas who present with possible endovascular infection.

Safety of Outpatient Parenteral Antimicrobial Therapy in Nonagenarians.

BACKGROUND: Although widely accepted for adults, the safety of outpatient parenteral antimicrobial therapy (OPAT) in very old patients has not been examined. METHODS: Nonagenarians (age ≥90 years) discharged from the hospital on OPAT over a 5-year period were identified from the Cleveland Clinic OPAT Registry. Three matched controls (<90 years) were selected for each nonagenarian. Times to OPAT-related emergency department (ED) visit and OPAT-related readmission were compared across the 2 groups in multivariable subdistribution proportional hazards competing risks regression models. Incidence of adverse drug events and vascular access complications were compared using negative binomial regression. RESULTS: Of 126 nonagenarians and 378 controls, 7 were excluded for various reasons. Among the remaining 497 subjects, 306 (62%) were male, 311 (63%) were treated for cardiovascular or osteoarticular infections, and 363 (73%) were discharged to a residential health care facility. The mean (SD) ages of nonagenarians and controls were 92 (2) and 62 (16) years, respectively. Compared with matched controls, being a nonagenarian was not associated with increased risk of OPAT-related ED visit (hazard ratio [HR], 0.77; 95% CI, 0.33-1.80; P = .55), OPAT-related readmission (HR, 0.78; 95% CI, 0.28-2.16; P = .63), adverse drug event from OPAT medications (incidence rate ratio [IRR], 1.00; 95% CI, 0.43-2.17; P = .99), or vascular access complications (IRR, 0.66; 95% CI, 0.27-1.51; P = .32). Nonagenarians had a higher risk of death overall (HR, 2.64; 95% CI, 1.52-4.58; P < .001), but deaths were not from OPAT complications. CONCLUSIONS: Compared with younger patients, OPAT in nonagenarians is not associated with higher risk of OPAT-related complications. OPAT can be provided as safely to nonagenarians as to younger patients.

Feasibility of electronic sleep disorder screening in healthcare workers of a large healthcare system.

STUDY OBJECTIVES: Many healthcare workers live with sleep disorders and may be unaware of their condition. We aimed to ascertain sleep disorder symptoms including high-risk obstructive sleep apnea (hrOSA), significant insomnia, and excessive daytime sleepiness (EDS) by work shift in a sample of healthcare workers. We aim to inform the development of a mobile application for sleep disorder screening and electronically-delivered follow-up recommendations. METHODS: An initial survey, including the Epworth Sleepiness Scale (ESS) for EDS, Insomnia Severity Scale (ISI) for insomnia, and STOP questionnaire for hrOSA, was completed by healthcare workers at the Cleveland Clinic. A follow-up survey sent ∼3-6 months after screening assessed perceptions of the utility of screening and subsequent actions taken by those with abnormal scores. RESULTS: 871 of 2851 (30.7%) workers who participated had abnormal ESS scores, with a significantly greater portion of night shift workers with abnormal scores compared to day or evening shift workers (p < 0.001). 27.5% of all workers had moderate to severe insomnia symptoms, with higher percentages of moderate or severe scores in evening and night shift workers (p < 0.001). 36.9% of workers had hrOSA, and of those previously diagnosed with obstructive sleep apnea (OSA) and using positive airway pressure therapy, over 90% reported treatment adherence (≥4 h per night). At follow-up, 92% of 484 respondents believed that sleep screening was valuable, with most taking some action after receiving abnormal results and over a quarter seeking sleep center treatment. CONCLUSIONS: Many healthcare workers, especially shift workers, experience sleep disorder symptoms, and our findings suggest that electronic sleep disorder symptom screening is feasible.

Clostridium septicum-infected aortic aneurysm or graft is a deadly diagnosis.

BACKGROUND: Clostridium septicum is an anaerobic, motile, spore-forming, toxin-producing gram-positive bacillus that can lead to rapidly progressive gas gangrene due to the release of alpha toxin. Aortic aneurysm secondary to C. septicum infection is a rare condition with 60 cases reported in the literature; however, we have recently treated several patients with the condition in our large tertiary care and aortic center. METHODS: Blood and tissue culture results collected between January 2005 and January 2018 and maintained in the microbiology laboratory database at the Cleveland Clinic were reviewed to identify those with C. septicum reported. Each was reviewed to determine radiographic or histopathologic correlation with aortic disease. RESULTS: Seven cases of C. septicum aortitis were reviewed. Underlying malignant disease was found in four cases and a history of remote malignant disease in one case. The most common location for infection was the infrarenal abdominal aorta. Vascular surgery had previously been performed in three of the cases. Five of the seven patients underwent operative repair. All patients were treated with ß-lactam antibiotics. The two patients who did not undergo an operation died, which is consistent with the 100% mortality described in the literature. Of the five patients who underwent an operation, there was only one documented survivor and one was lost to follow-up. CONCLUSIONS: In the largest reported case series, only a small percentage of patients with C. septicum-infected aortic aneurysms survived >1 year. In the patients described, those who did not receive an operation had 100% mortality. Earlier recognition and prompt operation with appropriate antimicrobial therapy are needed to improve the outcome of patients diagnosed with this rare infection.

Emergency department visits during outpatient parenteral antimicrobial therapy: a retrospective cohort study.

Objectives: Patients receiving outpatient parenteral antimicrobial therapy (OPAT) may require emergency department (ED) visits to manage complications. This study's purpose was to identify risk factors for ED visits during OPAT and risk factors for hospitalization among patients with ED visits. Methods: All OPAT courses initiated between 1 January 2013 and 1 January 2017 at Cleveland Clinic were identified. The first OPAT course per patient was included. For these, ED visits within 30 days were identified. Reasons and risk factors for these visits were sought, as were risk factors for hospitalization among patients visiting the ED. Results: Among 8263 patients on OPAT, 381 (4.6%) had at least one ED visit, an additional 1133 (14%) were hospitalized and an additional 50 (0.6%) died, within 30 days. One hundred and ninety-three ED visits (51%) were OPAT related. In a multivariable subdistribution proportional hazards competing risks regression model, prior ED visit (preceding year) was most strongly associated with ED visits (HR 2.29, 95% CI 1.76-2.98, P = 8.1 × 10-10). Eighty-five visits (22%) led to hospitalization. Compared with non-OPAT-related reasons, visits for vascular access complications were associated with lower odds of hospitalization (OR 0.36, 95% CI 0.14-0.83, P = 0.022) and visits for worsening infection with higher odds (OR 18.95, 95% CI 5.50-79.85, P = 1.2 × 10-7). Conclusions: Compared with patients without, patients with prior ED visit have a 2.3-fold higher hazard of an ED visit within 30 days of OPAT initiation. Visits for worsening infection are much more likely to result in hospitalization than those for vascular access complications.

Fighting fungus with a laser and a hose: Management of a giant Candida albicans implantable cardioverter-defibrillator lead vegetation with simultaneous AngioVac aspiration and laser sheath lead extraction.

Infections involving internal cardiac devices can be very challenging to treat, and almost universally require complete device extraction for successful management. Of the pathogens that cause device-related endocarditis, fungi such as Candida albicans are notoriously difficult to manage because of their propensity to produce large vegetations and the need for long-term treatment with potentially toxic medications. Furthermore, individuals who develop fungal, device-associated endocarditis are typically among the most complex patients, with significant comorbidities that place them at high risk for open heart procedures such as surgical device extraction. We present a case of one such patient in whom treatment of Candida albicans device-related endocarditis was managed using AngioVac® aspiration of a large right atrial vegetation with simultaneous laser sheath extraction of the implantable cardioverter-defibrillator lead.

Navigating pneumococcal vaccination in adults.

With two nonequivalent vaccines available and different recommendations for different patient populations, vaccination against Streptococcus pneumoniae can be confusing. Here we try to clarify the situation.

Vascular access complications during outpatient parenteral antimicrobial therapy at home: a retrospective cohort study.

OBJECTIVES: The need for indwelling vascular access for outpatient parenteral antimicrobial therapy (OPAT) places patients at risk of vascular access complications. The purpose of this study was to describe vascular access complications during OPAT at home, and identify factors associated with their occurrence. METHODS: All OPAT courses carried out at home for patients at Cleveland Clinic in 2013 were identified from the institution's OPAT registry. The first OPAT course per patient was included. Vascular access complications that occurred during the treatment course were abstracted from the electronic medical record. Only complications that triggered a clinical intervention were included. RESULTS: The 1461 included OPAT courses encompassed 33,579 OPAT days of treatment. One-hundred-and-forty-four vascular access complications occurred in 131 OPAT courses (9% of OPAT courses, 4.29 complications per 1000 OPAT days). The most common complication was occlusion (53% of all complications). Hickman catheters [incidence rate ratio (IRR) 0.20, 95% CI 0.03-0.63] and indwelling ports (IRR 0.25, 95% CI 0.04-0.78) were associated with lower complication rates than peripherally inserted central catheters, as was increasing age (IRR 0.99, 95% CI 0.98-1.00). Log OPAT duration (IRR 1.60, 95% CI 1.28-2.03), female sex (IRR 1.62, 95% CI 1.16-2.28) and injection drug use (IRR 3.32, 1.16-7.46) were associated with increased risk of vascular access complications. CONCLUSIONS: Nine percent of OPAT courses at home have at least one vascular access complication requiring clinical intervention. Longer OPAT duration, younger age, female sex and injection drug use are associated with increased risk of vascular access complications.

Ceftaroline fosamil: A super-cephalosporin?

Ceftaroline is a broad-spectrum cephalosporin used to treat infections caused by a variety of microorganisms, including methicillin-resistant Staphylococcus aureus (MRSA) and multidrug-resistant Streptococcus pneumoniae. However, it is not active against Pseudomonas aeruginosa, Bacteroides fragilis, and carbapenem-resistant Enterobacteriaceae. Its approved indications include community-acquired bacterial pneumonia and bacterial infections of skin and skin structures. It has also been used off-label to treat osteomyelitis, endocarditis, and meningitis caused by ceftaroline-susceptible organisms.

Heart valve culture and sequencing to identify the infective endocarditis pathogen in surgically treated patients.

BACKGROUND: Testing excised valves in surgically treated infective endocarditis (IE) patients provides an opportunity to identify the microbial etiology of IE. Microbial sequencing (universal bacterial, mycobacterial, or fungal polymerase chain reaction followed by DNA sequencing) of valves can identify microorganisms accurately, but the value it adds beyond information provided by blood and valve cultures has not been adequately explored. METHODS: Three hundred fifty-six patients who underwent surgery for active IE from January 1, 2010, to January 1, 2013, were identified from our cardiovascular information registry and outpatient parenteral antibiotic therapy registry. Their records were reviewed to identify 174 patients whose valves were sent for sequencing. The microbial etiology of IE was defined using comprehensive clinical, pathologic, and microbiological criteria. Blood culture, valve culture, and valve sequencing were examined to determine how frequently they identified the definitive cause of IE. RESULTS: Of the 174 patients, 162 (93%) had acute inflammation on histopathologic examination of their valves. Valve sequencing was significantly more sensitive than valve culture in identifying the causative pathogen (90% versus 31%, p < 0.001), and yielded fewer false positive results (3% versus 33%, p <0.001). The pathogen would not have been identified in 25 patients (15%) had it not been for valve sequencing. All the value provided by sequencing was attributable to bacterial DNA sequencing; mycobacterial and fungal sequencing provided no additional information beyond that provided by blood culture, histopathology, and valve culture. CONCLUSIONS: Valve sequencing, not valve culture, should be considered the primary test for identifying bacteria in excised cardiac valves.

The role of parental attitudes and provider discussions in uptake of adolescent vaccines.

The purpose of this study was to examine the relationship between parental vaccine attitudes, the number of specific vaccines discussed with a provider, and immunization outcomes including discussing immunization with their teen, knowledge of adolescent vaccine schedule, and their son or daughter being up-to-date on recommended vaccines using a nationally weight sample. Parents completed an internet-based survey between December 2012 and January 2013 and we computed a vaccine attitude scale (higher scores indicating stronger and more positive attitudes toward vaccination of teen) for each parent and categorized them into one of three groups: low (n=76), medium (n=207) or high (n=215). We also constructed a vaccine discussion scale representing the number of vaccines discussed with their adolescent's physician. Parents who were identified as having high vaccine attitudes were significantly more likely to report their physician talked with them about a particular vaccine. Using logistic regression and controlling for respondent's gender and age, income, and teen's gender, we found medium as compared to low-attitude parents had a 6.21 (95%CI=3.08, 12.51) greater odds of reporting that their teen had all recommended vaccines. Similarly, high as compared to low-attitude parents reported a 23.02 (95% CI=11.27, 46.99) greater odds of having a teen who was up-to-date on recommended vaccines. We detected that for each additional vaccine discussed, there was a 1.24 (95%CI=1.11, 1.39) increase in odds of the teen having all recommended vaccines. Parental immunization attitudes and provider discussion about vaccines are key ingredients to improving immunization rates among adolescents. While some parents may be reluctant to immunize their son or daughter with a recommended vaccine, vaccine-specific discussions between physicians and parents represent an important first step to continued discussions with providers regarding vaccination. Moreover, vaccine discussions must occur within the context of ongoing conversations about health and disease prevention.

Clinical utility of cerebral angiography in the preoperative assessment of endocarditis.

Cerebral angiography is an invasive procedure utilized without supporting guidelines in preoperative evaluations of infective endocarditis (IE). It is used to identify mycotic intracranial aneurysm, which is suspected to increase the risk of intracranial bleeding during cardiac surgery. Our objectives were to: (1) assess the utility of cerebral angiography by determining which subset of IE patients benefit from its performance; and (2) identify clinical and noninvasive screening tests that can preclude the need for invasive cerebral angiography. Retrospective analysis was performed of all patients treated surgically for IE from 7/2007 to 1/2012 and discharged with medical treatment for IE from 7/2007 to 7/2009 presenting to a large academic center. Of the 151 patients who underwent cerebral angiography, mycotic aneurysm was identified in seven (prevalence=4.6%; 95% CI 2.3-9.3%). Five had viridans group streptococci as the causative IE microorganism (p=0.0017). Noninvasive imaging and particularly absence of intracranial bleed on magnetic resonance imaging conveys a negative predictive value (NPV) of 0.977 (95% CI 0.879-0.996). Absence of a focal neurologic deficit or altered mental status convey a NPV of 0.990 (95% CI 0.945-0.998) and 0.944 (95% CI 0.883-0.974), respectively. Clinical suspicion for mycotic aneurysm and thus utilization of cerebral angiography is likely necessary only in the setting of acute neurologic deficits and when noninvasive imaging demonstrates acute intracranial bleed. A novel association between viridans group streptococci and intracranial mycotic aneurysm is demonstrated.

Adverse events, healthcare interventions and healthcare utilization during home infusion therapy with daptomycin and vancomycin: a propensity score-matched cohort study.

OBJECTIVES: Vancomycin and daptomycin are the two most frequently prescribed parenteral antimicrobials for resistant Gram-positive bacterial infections. The purpose of this study was to compare antimicrobial adverse event rates and associated healthcare interventions and healthcare utilization in patients treated with the two antimicrobials. METHODS: All patients aged ≥18 years, discharged home from Cleveland Clinic on outpatient parenteral antimicrobial therapy (OPAT) with daptomycin or vancomycin between 1 July 2007 and 30 June 2010 were screened. Logistic regression models were built to calculate propensity to be treated with daptomycin for each patient. Propensity score-matched vancomycin-treated controls were identified for each daptomycin-treated patient. Adverse event, healthcare intervention and healthcare utilization rates during OPAT were compared in the matched cohort using negative binomial regression models. RESULTS: One thousand, two hundred and eighty-eight patients were identified. Three-to-one matching provided the best matching characteristics and identified 119 daptomycin-treated subjects (2518 OPAT days) and 357 vancomycin-treated controls (6649 OPAT days). The mean patient age was 56 years and the mean OPAT duration was 19 days. Antimicrobial adverse event rates for the daptomycin and vancomycin groups were 3.2 and 7.7 per 1000 OPAT days, respectively [relative risk (RR) 0.38; 95% CI 0.15-0.86; P = 0.02]. Antimicrobial intervention rates were 5.6 and 27.1 per 1000 OPAT days, respectively (RR 0.21; 95% CI 0.11-0.36; P < 0.001). Readmissions for worsening infection or treatment complication were not significantly different between daptomycin (5%) and vancomycin (7%). CONCLUSIONS: Patients receiving daptomycin at home have 60% fewer antimicrobial adverse events and require 80% fewer antimicrobial interventions than similar patients receiving vancomycin.

Association of laboratory test result availability and rehospitalizations in an outpatient parenteral antimicrobial therapy programme.

OBJECTIVES: Laboratory tests are usually requested for monitoring during outpatient parenteral antimicrobial therapy (OPAT), but these recommendations are not always followed. The purpose of this study was to determine whether rehospitalization during the OPAT course is associated with the availability of these test results to the treating physician. METHODS: Electronic health records (EHRs) from all patients in the Cleveland Clinic OPAT registry with start dates from 1 January to 28 February 2011 were reviewed in a retrospective cohort study. Comprehensive data on patient and OPAT characteristics were obtained for the first OPAT course per patient. Availability of laboratory test results was defined as documentation of results of at least one recommended test in the health system's EHR. Proportions of patients rehospitalized were compared for OPAT courses with test results available and non-available. Adjustments were made for patient age, hospital length of stay, anticipated OPAT duration, OPAT site and Charlson comorbidity index score. RESULTS: Four hundred patients received OPAT during the study period; 60% at home, 36% in skilled nursing facilities or long-term acute care facilities and 4% in other settings. Recommended monitoring laboratory test results were available to infectious disease physicians in 291 (73%) OPAT episodes. There were 82 patient readmissions (21%) while on OPAT. In a multivariable logistic regression model, non-availability of recommended test results was independently associated with readmissions while on OPAT (adjusted OR 2.53; 95% CI 1.36-4.73). CONCLUSIONS: Non-availability of recommended test results to treating physicians for patients on OPAT is associated with increased readmissions during OPAT.

Endovascular infections caused by Histoplasma capsulatum: a case series and review of the literature.

CONTEXT: Endovascular infection is an uncommon but devastating manifestation of histoplasmosis, which is often diagnosed late in disease. OBJECTIVES: To evaluate the clinical and pathologic characteristics of patients with endovascular infections caused by Histoplasma capsulatum. DESIGN: All cases of patients with documented endovascular histoplasmosis at a single tertiary care center in an endemic region during the period 1993-2010 were reviewed. RESULTS: Patients presented with a subacute febrile illness and a history of endovascular devices. All patients had positive Histoplasma serology. Routine bacterial culture results were negative for all patients. In addition to yeast forms typical of histoplasmosis, pathologic findings also revealed mycelial forms in 4 of 5 patients. Inflammation was scant. Urinary antigen detection was positive in 4 of 5 patients and Histoplasma blood culture results were positive for 3 of 5 patients. Four patients were treated with a combination of surgical and medical therapy, which consisted of amphotericin B followed by itraconazole; these 4 patients had complete resolution of symptoms and no documented relapse. One patient died before planned surgery. CONCLUSIONS: Histoplasma capsulatum endovascular infections are clinically characterized by a subacute febrile illness with negative bacterial cultures in patients with prosthetic endografts or valves. Noninvasive diagnostics are often the initial clue to the diagnosis. Combined medical and surgical treatment is associated with survival. On histopathologic examination both mycelial and yeast forms are often observed, with absent to minimal tissue inflammatory reaction.

Identifying barriers to adult pneumococcal vaccination: an NFID task force meeting.

Pneumococcal infection is common in adults, and invasive disease is associated with a high mortality rate. Pneumococcal polysaccharide vaccine can prevent invasive pneumococcal disease and is recommended for people aged ≥ 65 years and for younger adults with high-risk chronic conditions; however, vaccination rates are suboptimal in all of these groups. A multidisciplinary task force meeting examined ways to increase vaccination rates in the target populations. Barriers to vaccination include lack of awareness of the disease or vaccine among vaccination candidates and health care providers, failure to assume responsibility for vaccination, competing priorities, incomplete or inaccessible documentation of previous vaccines, and health care system delivery challenges. Efforts to address these barriers should use appropriate methods. For example, potential vaccine recipients might be motivated by a message from a community leader, whereas health care providers are more apt to offer a vaccine when reminded that it is a recommended best practice. All health care providers need to accept responsibility for vaccination so that this preventive measure becomes a high priority in the care of patients at risk for serious pneumococcal infection.

Antimicrobial stewardship at transition of care from hospital to community.

Mandatory infectious disease consultation for parenteral antimicrobials at hospital discharge resulted in avoiding postdischarge parenteral antimicrobials in 28% of patients. No emergency department visit or rehospitalization within 30 days for these patients was a consequence of parenteral antimicrobial avoidance. Antimicrobial stewardship at transition of care is effective in reducing unnecessary antimicrobial use.
