Respiratory Complaints

Background: Coronavirus disease 2019 (COVID-19) is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). SARS-CoV-2 RNA can be detected by real-time reverse-transcription polymerase chain reaction (RT-PCR) for several weeks after infection. Discerning persistent RT-PCR positivity versus reinfection is challenging and the frequency of COVID-19 reinfections is unknown. We aimed to determine the frequency of clinically suspected reinfection in our center and confirm reinfection using viral whole-genome sequencing (WGS). Methods: The University of Iowa Hospitals and Clinics (UIHC) is an 811-bed academic medical center. Patients with respiratory complaints undergo COVID-19 RT-PCR using nasopharyngeal swabs. The RT-PCR (TaqPath COVID-19 Combo kit) uses 3 targets (ORF1ab, S gene, and N gene). We identified patients with previous laboratory-confirmed COVID-19 who sought care for new respiratory complaints and underwent a repeated SARS-CoV-2 test at least 45 days from their first positive test. We then identified patients with median RT-PCR cycle threshold (Ct) values. Results: During the study period, 13,603 patients had a SARS-CoV-2– positive RT-PCR. Of these, 296 (2.2%) had a clinical visit for new onset of symptoms and a repeated RT-PCR assay >45 days from the first test. Moreover, 29 patients (9.8%) had a positive RT-PCR assay in the repeated testing. Ct values were available for samples from 25 patients; 7 (28%) had Ct values. Conclusions: In patients with a recent history of COVID-19 infection, repeated testing for respiratory symptoms was infrequent. Some had a SARS-CoV-2–positive RT-PCR assay on repeated testing, but only 1 in 4 had Ct values suggestive of a reinfection. We confirmed 1 case of reinfection using WGS.Funding: NoDisclosures: None

Abstract Objective: Patients admitted to the hospital may unknowingly carry SARS-CoV-2 and hospitals have implemented SARS-CoV-2 admission screening. However, because SARS-CoV-2 RT-PCR may remain positive for months after infection, positive results may represent active or past infection. We determined the prevalence and infectiousness of patients who were admitted for reasons unrelated to COVID-19 but tested positive on admission screening. Methods: We conducted an observational study at the University of Iowa Hospitals & Clinics from July 7 to October 25, 2020. All patients admitted without suspicion of COVID-19 infection were included and medical records of those with a positive admission screening test were reviewed. Infectiousness was determined using patient history, PCR cycle threshold (Ct) value, and serology. Results: A total of 5,913 patients were screened and admitted for reasons unrelated to COVID-19. Of these, 101 had positive admission RT-PCR results. Thirty-six patient were excluded because they had respiratory signs/symptoms on admission on chart review. Sixty-five patients (1.1%) did not have respiratory symptoms. A total of 55 patients had Ct values available and were included in this analysis. The median age was 56 years, and (51%) were male. Our assessment revealed that 23 patients (42%) were likely infectious. The median duration of in-hospital isolation was five days for those likely infectious and two days for those deemed non-infectious. Conclusions: COVID-19 infection was infrequent among patients admitted for reasons unrelated to COVID-19. An assessment of the likelihood of infectiousness using clinical history, RT-PCR Ct values, and serology may help discontinue isolation and conserve resources.

Dying Patients

Background: The quality of perimortem care received by patients who died at our hospitals was unknown. Objective: To describe the quality of hospital care experienced in the last week of life, as perceived by decedents’ families. Design: Telephone survey that included established measures and investigator-developed content. Setting: Large, tertiary care center known for high-quality, cost-effective care. Participants: Family members of 104 patients who died in-hospital (10% of annual deaths) over the course of 1 year. Intervention: None. Measurements: Participant perceptions of the decedent’s care, including symptom management, personal care, communication, and care coordination. Results: Decedents were mostly male (64%), white (96%), married (73%), and Christian (91%). Most survey participants were spouses of the decedent (68%); they were predominately white (98%), female (70%), and Christian (90%) and had a median age of 70 years (range, 35-91 years). Overall satisfaction was high. Pain, dyspnea, and anxiety or sadness were highly prevalent among decedents (73%, 73%, and 55%, respectively) but largely well managed. Most participants believed that decedents were treated respectfully and kindly by staff (87%) and that sufficient help was available to assist with medications and dressing changes (97%). Opportunities for improvement included management of decedents’ anxiety or sadness (29%) and personal care (25%), emotional support of the family (57%), communication regarding decedents’ illness (29%), and receiving contradictory or confusing information (33%). Conclusion: Despite high satisfaction with care overall, we identified important unmet needs. Addressing these gaps will improve the care of dying patients.

Abstract Background: Institutions face increasing charges related to molecular genetic testing for neurological diseases. The literature contains little information on the utilization and performance of these tests. Methods: A retrospective utilization review was performed to determine the diagnostic yield of neurogenetic tests ordered during calendar year 2005 at a large academic medical center in the western United States. Results: Overall, a relevant mutation was identified in 30.2% of the 162 patients tested and in 21.5% of the 121 probands, defined as patients for whom no mutation has been previously identified in a family member. Patients with muscle weakness (n = 65) had a mutation detected in 26.2% of all patients and 23.5% of probands (n = 51), with an estimated testing cost per positive result of $3190. Patients tested for neuropathy (n = 36) had a mutation detected in 27.8% of patients and 22.6% of probands (n = 31), with an estimated cost per positive result of $5955. Patients with chorea (n = 25) had a positive result obtained in 68% of patients and 71.4% of probands (n = 7); the estimated cost per positive test was $440. Other diagnostic categories evaluated include ataxias (n = 18; yield, 11.1%; $7620 per positive), familial stroke or dementia syndromes (n = 8; yield, 12.5%; $6760 per positive), and multisystem mitochondrial disorders (n = 10; yield, 20%; $6485 per positive). Conclusions: Expert clinicians at a tertiary care center who ordered neurogenetic tests obtained a positive result in 21.5% of patients without previously identified familial mutations. These results can be used for comparison and to help establish utilization guidelines for neurogenetic testing.

Abstract Background Cryptococcosis is an invasive fungal infection that causes pneumonia and extrapulmonary infection. This study explores its presentations, diagnostic tests, and outcome in different groups over a 12-year period at an academic medical center. Methods This was a retrospective study of the patients treated at University of Kentucky HealthCare from October 16, 2005 to October 15, 2017. Inclusion criteria were positive cryptococcal antigen (Ag), positive culture, or presence of yeast morphologically consistent with Cryptococcus on cyto- or histopathology. Patients were divided into HIV-infected, solid-organ transplant (SOT) recipients, and non-HIV/non-transplant groups. Cryptococcal meningitis comprised of either positive CSF Ag, culture, cytology or histopathology. Results A total of 114 patients were identified; 23 HIV-infected, 11 SOT recipients and 80 non-HIV/non-transplant patients (Table 1). Cryptococcus neoformans was the most common yeast isolated (91.8%). Cryptococcal meningitis was seen in 56% of total patients whereas 27% had isolated cryptococcal pneumonia (P < 0.01). Blood cultures and serum Ag were positive in 34% and 70%, respectively. Only 8.7% of HIV-infected patients had isolated pulmonary cryptococcosis compared with 36.4% in SOT recipients (P < 0.01). In patients with cryptococcal meningitis, abnormal CSF cell count, protein, or glucose was noted in 85.3%; India ink was positive in 61.3% and CSF culture was positive in 73.4% (Table 2, Figure 1). CSF cryptococcal Ag was detected in 95.6% cases if CSF cultures were positive, whereas serum Ag was positive in only 85.1% of meningitis cases. Mortality was seen in 48.6% (17/35) of patients with cirrhosis/liver disease, compared with 21.5% (17/79) of non-cirrhosis/liver disease (P = 0.003). Transplant group had 54.5% mortality compared with 26.1% in HIV group (P = 0.016). Conclusion Cryptococcal meningitis was the most common presentation for cryptococcal disease in all three groups. Isolated pulmonary disease was least common in the HIV-infected group. Inpatient mortality rate was higher in patients with cirrhosis/liver disease and transplant group compared with those without cirrhosis/liver disease and HIV group, respectively. It is imperative to rule out meningitis in immunosuppressed patients with cryptococcal pneumonia. Disclosures All authors: No reported disclosures.

Respiratory Coronavirus

Background: Hospitalized patients may unknowingly carry severe acute respiratory coronavirus virus 2 (SARS-CoV-2), even if they are admitted for other reasons. Because SARS-CoV-2 may remain positive by reverse-transcriptase polymerase chain reaction (RT-PCR) for months after infection, patients with a positive result may not necessarily be infectious. We aimed to determine the frequency of SARS-CoV-2 infections in patients admitted for reasons unrelated to coronavirus disease 2019 (COVID-19). Methods: The University of Iowa Hospitals and Clinics is an 811-bed tertiary-care center. We use a nasopharyngeal SARS-CoV-2 RT-PCR to screen admitted patients without signs or symptoms compatible with COVID-19. Patients with positive tests undergo a repeat test to assess cycle threshold (Ct) value kinetics. We reviewed records for patients with positive RT-PCR screening admitted during July–October 2020. We used a combination of history, serologies, and RT-PCR Ct values to assess and qualify likelihood of infectiousness: (1) likely infectious, if Ct values were <29, or (2) likely not infectious, if 1 or both samples had Cts <30 with or without a positive SARS-CoV-2 antinucleocapsid IgG/IgM test or history of a positive result in the past 90 days. Contact tracing was only conducted for patients likely to be infectious. We describe the isolation duration and contact tracing data. Results: In total, 6,447 patients were tested on hospital admission for any reason (persons under investigation or admitted for reasons other than COVID-19). Of these, 240 (4%) had positive results, but 65 (27%) of these were admitted for reasons other than COVID-19. In total, 55 patients had Ct values available and were included in this analysis. The median age was 56 years (range, 0–91), 28 (51%) were male, and 12 (5%) were children. The most frequent admission syndromes were neurological (36%), gastrointestinal (16%), and trauma (16%). Our assessment revealed 23 likely infections (42%; 14 definite, 9 possible) and 32 cases likely not infectious (58%). The mean Ct for patients who were likely infectious was 22; it was 34 for patients who were likely not infectious. Mean duration of in-hospital isolation was 6 days for those who were likely infectious and 2 days for those who were likely not infectious. We detected 8 individuals (1 healthcare worker and 7 patients) who were exposed to a likely infectious patient. Conclusions: SARS-CoV-2 infection in patients hospitalized for other reasons was infrequent. An assessment of the likelihood of infectiousness including history, RT-PCR Cts, and serology may help prioritize patients in need of isolation and contact investigations.Funding: NoDisclosures: None

Objective: Identify knowledge deficits about alternate airways (AAs) (tracheostomy and laryngectomy) among physicians across multiple specialties a tertiary institution and to assess the impact of an educational lecture on improving deficits. Methods: Study Design: Cross-sectional assessment. Setting: Academic medical center. Subjects and Methods: An anonymous 10-item, multiple choice assessment was given to physicians at a tertiary care center in the departments of Otolaryngology, Emergency Medicine, Family Medicine, General Surgery, Internal Medicine, and Pediatrics. An educational lecture on AAs was presented. Scores between a pre-lecture and a 3-month post-lecture assessment were compared. Data was analyzed using ANOVA and chi-squared analysis. Results: Otolaryngology physicians scored an average of 97.8%, while non-otolaryngology physicians scored 58.3% ( P < .05). Non-otolaryngology surgical physicians scored 68.4% while non-surgical physicians were lower at 55.1% ( P < .0001). Comparing pre-lecture to post-lecture scores, all non-otolaryngology physicians improved their scores significantly from 58.3% to 86.5% ( P < .005). Non-surgical physicians had significant improvement after the instructional lecture, closing the score gap with surgical physicians for the post-lecture assessment. Discussion: The care of patients with AAs requires an understanding of their basic principles. Our findings identify significant knowledge deficits among non-otolaryngologists. Through an instructional lecture, we demonstrated improvement in knowledge among non-otolaryngology physicians and durability of the knowledge after 3 months. Conclusions: Through an instructional lecture, we found tracheostomy and laryngectomy knowledge deficits can be identified and improved upon. Periodic reinforcement of basic principles for non-otolaryngology physicians may be a promising strategy to ensure the proper care of patients with AAs.

Background: Bats are recognized as important vectors in disease transmission. Frequently, bats intrude into homes and buildings, increasing the risk to human health. We describe bat intrusions and exposure incidents in our hospital over a 3-year period. Methods: The University of Iowa Hospitals and Clinics (UIHC) is an 811-bed academic medical center in Iowa City, Iowa. Established in 1928, UIHC currently covers 209,031.84 m2 (~2,250,000 ft2) and contains 6 pavilions built between 1928 and 2017. We retrospectively obtained bat intrusion calls from the infection prevention and control program call database at UIHC during 2018–2020. We have also described the event management for intrusions potentially associated with patient exposures. Results: In total, 67 bat intrusions occurred during 2018–2020. The most frequent locations were hallways or lounges 28 (42%), nonclinical office spaces 19 (14%), and stairwells 8 (12%). Most bat intrusions (65%) occurred during the summer and fall (June–November). The number of events were 15 in 2018, 28 in 2019, and 24 in 2020. We observed that the number of intrusions increased with the age of each pavilion (Figure 1). Of 67 intrusions, 2 incidents (3%) were associated with potential exposure to patients. In the first incident, reported in 2019, the bat was captured in a patient care area and released before an investigation of exposures was completed and no rabies testing was available. Also, 10 patients were identified as having had potential exposure to the bat. Among them, 9 patients (90%) received rabies postexposure prophylaxis. In response to this serious event, we provided facility-wide education on our bat control policy, which includes the capture and safe handling of the bat, assessment of potential exposures, and potential need for rabies testing. We also implemented a bat exclusion project focused on the exterior of the oldest hospital buildings. The second event, 1 patient was identified to have potential exposure to the bat. The bat was captured, tested negative for rabies, no further action was needed. Conclusions: Bat intrusions can be an infection prevention and control challenge in facilities with older buildings. Hospitals may need animal intrusion surveillance systems, management protocols, and remediation efforts.Funding: NoDisclosures: None

Many state-wide, city-wide, and hospital-wide changes have been implemented due to the ongoing COVID-19 crisis. We describe lessons learned in an anatomic pathology division at a tertiary care center during the peak of the COVID-19 pandemic in the hopes that knowledge of our experiences can benefit other pathology departments as they encounter this pandemic. Five categories that are critical in strategic planning for the COVID-19 pandemic are discussed: workload, departmental policy revisions, impact on faculty, workforce staffing, and impact on educational programs, including residency and fellowship training. Although the volume of COVID-19 testing had grown placing increased demands on the clinical pathology laboratory, the volume of anatomic pathology cases had declined during the COVID-19 peak. Lessons learned were widespread including changes in the anatomic pathology workflow due to declining surgical and cytologic case volumes and increases in autopsy requests. Modifications were required in gross room policies, levels of personal protective equipment, and workforce. Travel and meeting policies were impacted. Adaptations to residency and fellowship programs were vast and included innovations in didactic and interactive education. We must learn from our experiences thus far in order to move forward, and we hope that our experiences in an anatomic pathology department in the epicenter of the COVID-19 pandemic can help other pathology departments across the country.

Utilization Data

Background: As more US hospitals report antibiotic utilization to the CDC, standardized antimicrobial administration ratios (SAARs) derived from patient care unit-based antibiotic utilization data will increasingly be used to guide local antibiotic stewardship interventions. Location-based antibiotic utilization surveillance data are often utilized given the relative ease of ascertainment. However, aggregating antibiotic use data on a unit basis may have variable effects depending on the number of clinical teams providing care. In this study, we examined antibiotic utilization from units at a tertiary-care hospital to illustrate the potential challenges of using unit-based antibiotic utilization to change individual prescribing. Methods: We used inpatient pharmacy antibiotic use administration records at an adult tertiary-care academic medical center over a 6-month period from January 2019 through June 2019 to describe the geographic footprints and AU of medical, surgical, and critical care teams. All teams accounting for at least 1 patient day present on each unit during the study period were included in the analysis, as were all teams prescribing at least 1 antibiotic day of therapy (DOT). Results: The study population consisted of 24 units: 6 ICUs (25%) and 18 non-ICUs (75%). Over the study period, the average numbers of teams caring for patients in ICU and non-ICU wards were 10.2 (range, 3.2–16.9) and 13.7 (range, 10.4–18.9), respectively. Units were divided into 3 categories by the number of teams, accounting for ≥70% of total patient days present (Fig. 1): “homogenous” (≤3), “pauciteam” (4–7 teams), and “heterogeneous” (>7 teams). In total, 12 (50%) units were “pauciteam”; 7 (29%) were “homogeneous”; and 5 (21%) were “heterogeneous.” Units could also be classified as “homogenous,” “pauciteam,” or “heterogeneous” based on team-level antibiotic utilization or DOT for specific antibiotics. Different patterns emerged based on antibiotic restriction status. Classifying units based on vancomycin DOT (unrestricted) exhibited fewer “heterogeneous” units, whereas using meropenem DOT (restricted) revealed no “heterogeneous” units. Furthermore, the average number of units where individual clinical teams prescribed an antibiotic varied widely (range, 1.4–12.3 units per team). Conclusions: Unit-based antibiotic utilization data may encounter limitations in affecting prescriber behavior, particularly on units where a large number of clinical teams contribute to antibiotic utilization. Additionally, some services prescribing antibiotics across many hospital units may be minimally influenced by unit-level data. Team-based antibiotic utilization may allow for a more targeted metric to drive individual team prescribing.Funding: NoneDisclosures: None

Abstract Objective The COVID-19 vaccine may hold the key to ending the pandemic, but vaccine hesitancy is hindering the vaccination of healthcare personnel (HCP). Design Before-after trial Participants and setting Healthcare personnel at a 790-bed tertiary care center in Tokyo, Japan. Interventions A pre-vaccination questionnaire was administered to HCP to examine their perceptions of the COVID-19 vaccine. Then, a multifaceted intervention involving (1) distribution of informational leaflets to all HCP, (2) hospital-wide announcements encouraging vaccination, (3) a mandatory lecture, (4) an educational session about the vaccine for pregnant or breastfeeding HCP, and (5) allergy testing for HCP at risk of allergic reactions to the vaccine was implemented. A post-vaccination survey was also performed. Results Of 1,575 HCP eligible for enrollment, 1,224 (77.7%) responded to the questionnaire, 43.5% (n =533) expressed willingness to be vaccinated, 48.4% (n = 593) were uncertain, and 8.0% (n=98) expressed unwillingness to be vaccinated. The latter two groups were concerned about the vaccine’s safety rather than its efficacy. Post-intervention, the overall vaccination rate reached 89.7% (1,413/1,575), with 88.9% (614/691) of the pre-vaccination survey respondents who answered “unwilling” or “unsure” eventually receiving a vaccination. In the post-vaccination questionnaire, factors contributing to increased COVID-19 vaccination included information and endorsement of vaccination at the medical center (26.4%; 274/1,037). Conclusions The present, multifaceted intervention increased COVID-19 vaccinations among HCP at a Japanese hospital. Frequent support and provision of information were crucial for increasing the vaccination rate and may be applicable to the general population as well.
