Perspectives of Families and Healthcare Staff on the Design of Inpatient Hospital Rooms in Saudi Arabia.

Aim: This study aims to explore the relationship between the perspectives of both family members and healthcare staff regarding the design of hospital inpatient rooms. It investigates the impact of family presence on the healing environment and examines the influence of specific design elements within inpatient rooms on the extent of family presence. Background: The positive impact of family presence in healthcare settings is rooted in the notion that patients and their families are significant stakeholders in the care process. However, little is known about the influence of inpatient room design elements on family presence in healthcare settings in the Middle East. Methods: A questionnaire survey was conducted among 359 participants, encompassing patients, family visitors, and healthcare professionals from three hospitals in Saudi Arabia. The questionnaire items sought insights into the influence of design elements within inpatient rooms on family presence and the overall healing environment. Results: The results indicate a strong preference for single-patient rooms (74.5%), natural light (77.6%), comfortable seating (85.8%), and a family zone positioned by the window for unobstructed views of nature (50.5%). Furthermore, the study reveals that family presence is perceived to have positive effects on the healing environment (84.0%), patient safety (81.3%), and satisfaction with the care process (88.0%). Conclusion: This study proposes a design model for inpatient rooms that can effectively cater to the needs of patients and their families, thereby contributing to the overall improvement of healthcare building design.

Design of hospitals for the post-pandemic era: an international survey of design professionals on infection control design strategies

ABSTRACT The COVID-19 pandemic placed unpreceded stress on healthcare systems, highlighting their deficiencies and vulnerabilities. The risk of cross-infection among patients and healthcare workers increased significantly, hindering the overall healthcare process. Hospital design should meet the challenges that will be posed by future pandemics, especially infection control. This paper reports on the results of an online survey for healthcare design professionals and academics from across the globe. The questionnaire addressed how hospital design can contribute to the infection control during future pandemic situations. Respondents agreed that the benefits of designing hospitals to meet the needs of pandemic/emergency situations outweigh the additional cost, and that infection control should play a more pronounced role when designing hospitals for the coming era. Results indicate that the overall organization of hospitals should allow for the compartmentation of critical/isolation departments/units and the creation of separate circulation routes to suit this compartmentation during pandemic times. The circulation system of the emergency departments and Intensive Care Units (ICU) should allow for the separation of infectious patients from others during pandemic times. 20–30% of the ICU beds of tertiary level care hospitals should be designed as single patient rooms. 53% of these rooms should be easily convertible to Air-Borne-Infection Isolation (AII) rooms, 44% should have an additional space for adding anterooms during pandemics, and 55% of these rooms should have permanent storage spaces for Personal Protective Equipment. The inpatient units should also be designed to support infection control. AII rooms should be grouped in designated inpatient units.

Impact of Transitioning to Single-Patient Rooms on Prevention of Multidrug-Resistant Organisms in a Resource-Limited Facility

Background: Healthcare-associated infections (HAI) substantially increase hospital costs and lead to poor patient outcomes, particularly when caused by multidrug-resistant organisms (MDRO). To decrease MDRO transmission, isolation of colonized or infected patients in single rooms is recommended. However, single-patient isolation rooms are expensive to build and often unavailable in resource-limited hospitals. In 2023, an intensive care unit (ICU) at a large Brazilian tertiary hospital relocated from a space with an open floor plan to a newly built location with single-patient rooms. We evaluated the impact of this transition on acquisition of carbapenem-resistant Enterobacterales (CRE) colonization, HAI, and compliance with Hand Hygiene (HH) and Contact Precaution (CP) activities. Methods: We compared rates of CRE colonization acquisition, CRE colonization pressure, HAI, and compliance with HH and CP between pre- (March 1, 2022 – Feb 28, 2023) and post-implementation of single-rooms (March 1, 2023 - October 31, 2023) in a 12-bed surgical ICU. All patients were screened for CRE colonization on admission to the unit and weekly until discharge using rectal swab cultures. Colonization pressure was defined as the ratio of CRE-positive patient-days (PDs) to the total number of PDs. Rates of central-line associated blood-stream infections, ventilator-associated pneumonia, and catheter-associated urinary tract infections were monitored. HH and CP compliance were monitored weekly by infection prevention staff outside of the unit. Poisson regression and multiple linear regression were used to compare rates between pre- and post-implementation periods. Results: Healthcare acquisition of CRE colonization remainedstable between pre- and post-implementation (incidence rate ratio: 0.88 (95%CI, 0.73-1.05; P=0.16) despite an increase in CRE colonization pressure of 8.6% over baseline (from 7.84% pre- to 16.39% post-implementation (95% confidence interval [CI], 4.13-12.96%; P=.001)). The latter was driven by reduced turnover of CRE-colonized patients in the post-implementation period (mean patient-day reduced by 10.33; 95%CI, 3.06-17.61; P=0.006). Incidence of HAIs also remained stable (global incidence 3.12 vs 3.30, pre- and post-intervention, respectively; P=0.2). HH compliance was high prior to the transition (95.7%) and increased slightly but not significantly post-intervention (97.5%; P=0.3). CP compliance improved by 9.83%, especially in gown and glove changes after each patient interaction, from 90.62% pre- to 100% post-implementation (95%CI, 1.52-17.22; P=.02). Conclusion The move to an ICU with exclusively single-patient rooms was associated with increase in CP compliance. This could help explain why HAI incidence and healthcare acquisition of CRE colonization remained stable despite a significant increase in CRE colonization pressure.Disclosure: Matias Salomao: Speaker - Cepheid

Effect of single-patient room design on the incidence of nosocomial infection in the intensive care unit: a systematic review and meta-analysis.

Previous studies have yielded varying conclusions regarding the impact of single-patient room design on nosocomial infection in the intensive care unit (ICU). We aimed to examine the impact of ICU single-patient room design on infection control. We conducted a comprehensive search of PubMed, Embase, the Cochrane Library, Web of Science, CNKI, WanFang Data, and CBM databases from inception to October 2023, without language restrictions. We included observational cohort and quasi-experimental studies assessing the effect of single- versus multi-patient rooms on infection control in the ICU. Outcomes measured included the nosocomial infection rate, incidence density of nosocomial infection, nosocomial colonization and infection rate, acquisition rate of multidrug-resistant organisms (MDROs), and nosocomial bacteremia rate. The choice of effect model was determined by heterogeneity. Our final analysis incorporated 12 studies involving 12,719 patients. Compared with multi-patient rooms in the ICU, single-patient rooms demonstrated a significant benefit in reducing the nosocomial infection rate (odds ratio [OR]: 0.68; 95% confidence interval [CI]: 0.59, 0.79; p < 0.00001). Analysis based on nosocomial infection incidence density revealed a statistically significant reduction in single-patient rooms (OR: 0.64; 95% CI: 0.44, 0.92; p = 0.02). Single-patient rooms were associated with a marked decrease in nosocomial colonization and infection rate (OR: 0.44; 95% CI: 0.32, 0.62; p < 0.00001). Furthermore, patients in single-patient rooms experienced lower nosocomial bacteremia rate (OR: 0.73; 95% CI: 0.59, 0.89; p = 0.002) and lower acquisition rate of MDROs (OR: 0.41; 95% CI: 0.23, 0.73; p = 0.002) than those in multi-patient rooms. Implementation of single-patient rooms represents an effective strategy for reducing nosocomial infections in the ICU. https://www.crd.york.ac.uk/PROSPERO/).

AI-Guided Computing Insights into a Thermostat Monitoring Neonatal Intensive Care Unit (NICU).

In any healthcare setting, it is important to monitor and control airflow and ventilation with a thermostat. Computational fluid dynamics (CFD) simulations can be carried out to investigate the airflow and heat transfer taking place inside a neonatal intensive care unit (NICU). In this present study, the NICU is modeled based on the realistic dimensions of a single-patient room in compliance with the appropriate square footage allocated per incubator. The physics of flow in NICU is predicted based on the Navier-Stokes conservation equations for an incompressible flow, according to suitable thermophysical characteristics of the climate. The results show sensible flow structures and heat transfer as expected from any indoor climate with this configuration. Furthermore, machine learning (ML) in an artificial intelligence (AI) model has been adopted to take the important geometric parameter values as input from our CFD settings. The model provides accurate predictions of the thermal performance (i.e., temperature evaluation) associated with that design in real time. Besides the geometric parameters, there are three thermophysical variables of interest: the mass flow rate (i.e., inlet velocity), the heat flux of the radiator (i.e., heat source), and the temperature gradient caused by the convection. These thermophysical variables have significantly recovered the physics of convective flows and enhanced the heat transfer throughout the incubator. Importantly, the AI model is not only trained to improve the turbulence modeling but also to capture the large temperature gradient occurring between the infant and surrounding air. These physics-informed (Pi) computing insights make the AI model more general by reproducing the flow of fluid and heat transfer with high levels of numerical accuracy. It can be concluded that AI can aid in dealing with large datasets such as those produced in NICU, and in turn, ML can identify patterns in data and help with the sensor readings in health care.

Hospitalized Patients' Sleep Quality Compared Between Multioccupancy Rooms and Single-Patient Rooms.

To evaluate patients' sleep quality in a former hospital with two-and four-bedded rooms compared to a new hospital that incorporated evidence-based design features, including exclusively single-patient rooms (SPRs). Hospitalized patients often report poor sleep quality due to both patient-related factors and hospital environmental factors. It is unclear if staying in an SPR in a hospital designed as a healing environment is associated with better sleep quality. In a before-after study, sleep quality, duration, and efficiency over 72 hr were measured with a sleep diary, GENEActiv accelerometer, and the Richards-Campbell Sleep Questionnaire (RCSQ) with scores ranging from 0 to 100, with higher scores reflecting better sleep. Participants were either staying alone in the former hospital with two-and four-bedded rooms (Group 1), sharing a room with one to three fellow patients (Group 2), or staying alone in a newly designed hospital with 100% SPRs (Group 3). We included 17 patients in Group 1, 32 patients in Group 2, and 56 patients in Group 3. Univariable linear mixed model analysis, controlling for night number, revealed that the RCSQ total score was lowest in Group 2 compared to the other two groups. In the multivariable analysis, the RCSQ score was also the lowest in Group 2, with a significant effect from covariate "use of night medication." Self-reported sleep quality of hospitalized patients in a hospital with 100% SPRs designed as a healing environment was slightly better than that of patients staying in multioccupancy rooms with fellow patients.

Energy Saving Opportunities through Glazing and Shading Alternatives

Windows are the weakest elements due to their high heat transfer coefficient and are responsible for 60% energy heat/gain loss. Healthcare buildings are one of the biggest consumers of energy due to continuous occupation hours and medical requirements, providing comfortable conditions for people in need of care and staff; yet recently less attention was given to healthcare buildings due to their unique operational requirements and advanced medical equipment. Thus, the main purpose of this study was to evaluate energy saving potentials of windows through glazing and shading alternatives over a case study. Within this study, a single patient room in Izmir Turkey has been chosen as a case study, and the room was simulated for sixteen scenarios generated by using four different glazing and shading systems. Each design scenario was simulated using DALEC for their lighting, heating, cooling, and total energy consumption. Results showed that lighting energy consumption constitutes the highest energy demand (up to 52%) and high transmitting glazing usage can reduce lighting loads. Finally, up to 16.3%, energy saving is possible only by changing shading and glazing types. Though there is a great diversity of glazing and shading types, this study’s outputs only reflect the selected four glazing and four shading system types that are offered by DALEC. Healthcare buildings spend a vast amount of energy to provide thermal and visual comfort for various user profiles. Considering the large number of patient rooms in healthcare facilities, only careful consideration of glazing or shadings can significantly contribute to energy savings. This study focuses on shading and glazing alternatives as an energy-saving strategy. For simulation, an underrecognized BES tool DALEC was hyped to show integrated thermal and visual energy consumption. The findings highlight that energy savings of up to 16.3% is possible.

Taking Advantage of Single Patient Rooms as a Major Support for the Healing Environment System in Egyptian Hospitals

Taking Advantage of Single Patient Rooms as a Major Support for the Healing Environment System in Egyptian Hospitals

A cost-effectiveness model for a decision to adopt temporary single-patient rooms to reduce risks of healthcare-associated infection in the Australian public healthcare system.

The cost-effectiveness of patient isolation as part of an infection prevention effort is poorly understood. The potential to reduce risks of transmission saving costs and improving health outcomes is strong, yet up front investments in patient isolation are required. We report a cost-effectiveness model to inform adoption of a portable single isolation rooms into Australian publicly funded acute hospitals. Information is harvested from a range of contemporary sources to reveal the expected changes to total costs and total health benefits measured by life years gain. An Incremental cost-effectiveness ratio is estimated with uncertainty in all model parameters included by probabilistic sensitivity analysis. The adoption decision was found to change total costs per 100,000 occupied bed-days by $1,429,011 and generate health benefits of 436 life years. The mean cost per life year gained is $3278. The probability an adoption decision is cost saving is 2.1%. There is some evidence that adoption of rediroom is likely to be a cost-effective solution for Australian hospitals. Important caveats and assumptions need to be considered when interpreting this conclusion.

Fatal outcome of isolated patients who suffered an in-hospital cardiac arrest

AimIsolation of patients in single-patient rooms for infection control precautions leads to less contact with medical staff. Our objective was to assess whether isolated patients who suffer an in-hospital cardiac arrest (IHCA) have lower survival as non-isolated IHCA patients. MethodsWe screened for IHCA occurrence and the isolation state in 75.987 patients that had been hospitalized from 2016 to 2019 at the university hospital. Primary endpoint was survival to discharge. Neurological outcome was assessed using the cerebral performance category scale. ResultsIn five consecutive years, 4,249 out of 75,987 patients (5.6%) had to be isolated for infection control precautions. In-hospital cardiac arrest occurred in 32 (0.8%) of these isolated patients and in 410 out of 71,738 non-isolated patients (0.6%) (p = 0.130). Propensity score matching yielded 30 isolated and 30 non-isolated patients who suffered an IHCA, without a difference in baseline characteristics and characteristics of cardiac arrests between the groups. Only one out of 30 isolated patients (3.3%) survived to discharge after IHCA compared to 11 non-isolated patients (36.6%) (risk difference, 33.3% [95% CI, 14.9%–51.7%]. None of the 30 isolated patients were discharged with good neurological outcomes compared to nine out of 30 non-isolated IHCA patients (30%) (risk difference, 30% [95% CI, 13.6%–46.4%]). In the multivariate analysis, patient isolation was an independent predictor of poor survival after IHCA (OR, 18.99; 95% CI, 2.467–133.743). ConclusionsIsolation of patients for infection control precautions is associated with considerable poorer survival and neurological outcome in case these patients are suffering an IHCA.

Integrated healthcare acoustics for patients, patient advocates, and staff in environments of care

COVID surges have demonstrated worldwide that overloaded critical care facilities cannot transform environments of care rapidly enough to satisfy patient, patient advocate, or staff expectations. Healthcare acoustics is identified as a vital yet understudied factor, linking the front lines of healthcare to patient well-being. Acoustic concerns are categorized, and existing architectural hardware and software means and proposed strategies are here discussed to be applied in both new and existing critical care facilities. Priority concerns focus on staff verbal and machine communications between single patient rooms with integral toilet/shower, adjacent corridors, nurse stations, and remote staff locations. The intent is to maintain uniformly high patient/staff communications and relevant documentation (e.g., for continuity of care, and liability) across all shifts. Integrated visual and acoustic communications between staff and equipment are explored, including projected machine display images minus noisy signals. Staff speech, background masking, and messaging to patients are considered via an “acoustic pillow,” and via a wireless headset for staff, permitting hands-free focus on empathetic patient care. HVAC can be supplied via low-velocity displacement air, served via perimeter floor ducting, and exhausted via toilet/showers. Integrated healthcare acoustics, arguably, can reduce patient and staff stresses critical to recovery and retention, respectively.

Intra-NICU Patient Transfers: A Study of Frequency and Family and Staff Perceptions

Aims:(a) Quantify frequency of patient moves within a NICU with single patient and semi-private rooms (SPR). (b) Compare staff and parent perceptions of these moves.Methods:A hospital administrative database was evaluated to quantify the frequency of moves. A Room Change Questionnaire was devised to evaluate perceptions from NICU families and staff.Results:Most families reported experiencing at least 1 patient move (92 percent), with the majority reporting at least 3 moves (58 percent). Staff perceived moves as negative significantly more than parents (p &lt; .01), and overreported negative family perceptions (p &lt; .01). Overall, moves did not bother families (52 percent); however, most families who moved 3 or more times reported at least 1 negative perception (63 percent).Conclusion:SFRs increase the number of patient moves. NICU staff’s perception is significantly more negative than family’s perception; however, most families who were moved frequently reported at least 1 negative perception.

Efficacy of Aerosol Reduction Measures for Dental Aerosol Generating Procedures.

Aerosol particles generated by dental procedures could facilitate the transmission of infectious diseases and contain carcinogen particles. Such particles can penetrate common surgical masks and reach the lungs, leading to increased risk for dental care professionals. However, the risk of inhaling contaminated aerosol and the effectiveness of aerosol reduction measures in dental offices remain unclear. The present study aimed to quantify aerosols produced by drilling and scaling procedures and to evaluate present recommendations for aerosol reduction. The concentration of aerosol particles released from the mock scaling and drilling procedures on dental mannequin were measured using a TSI Optical Particle Sizer (OPS 3330) during 15-min sessions carried out in a single-patient examination room. Using a drilling procedure as the aerosol source, the aerosol reduction performance of two types of high-volume evacuators (HVEs) and a commercial off-the-shelf air purifier was evaluated in a simulated clinical setting. Using either HVEs or the air purifier individually reduced the aerosol accumulated over the course of a 15-minutes drilling procedure at a reduction rate of 94.8 to 97.6%. Using both measures simultaneously raised the reduction rate to 99.6%. The results show that existing HVEs can effectively reduce aerosol concentration generated by a drilling procedure and can be further improved by using an air purifier. Following current regulatory guidelines can ensure a low risk of inhaling contaminated aerosol for dentists, assistants, and patients.

Factors contributing to a coronavirus disease 2019 (COVID-19) outbreak on a mixed medical-surgical unit in a Canadian acute-care hospital.

To identify preventable factors that contribute to the cross transmission of severe acute respiratory coronavirus virus 2 (SARS-CoV-2) to patients in healthcare facilities. A case-control study was conducted among inpatients on a coronavirus disease 2019 (COVID-19) outbreak unit. This study was conducted in a medical-surgical unit of a tertiary-care hospital in Nova Scotia in May 2021. Patients hospitalized on the unit for at least 12 hours and healthcare workers (HCW) working on the unit within 2 weeks of outbreak declaration were included. Risk factors for SARS-CoV-2 infection were analyzed using simple and multiple logistic regression. Whole-genome sequencing (WGS) was performed to identify SARS-CoV-2 strain relatedness. Network analysis was used to describe patient accommodation. SARS-CoV-2 infections were identified in 21 patients (29.6%) and 11 HCWs (6.6%). WGS data revealed 4 distinct clades of related sequences. Several factors likely contributed to the outbreak, including failure to identify SARS-CoV-2, a largely incomplete or unvaccinated population, and patient wandering behaviors. The most significant risk factor for SARS-CoV-2 infection was room sharing with an infectious patient, which was the only factor that remained statistically significant following multivariate analysis (odds ratio [OR], 9.2l; 95% confidence interval [CI], 2.04-41.67; P = .004). This outbreak likely resulted from admission of 2 patients with COVID-19, with subsequent transmissions to 17 patients and 11 staff. WGS and bioinformatics analyses were critical to identifying previously unrecognized nosocomial transmissions of SARS-CoV-2. This study supports strategies to reduce nosocomial transmissions of SARS-CoV-2, such as single-patient rooms, promotion of COVID-19 vaccination, and infection prevention and control measures including management of wandering behaviors.

Assessment of the effectiveness of ultraviolet-C disinfection on transmission of hospital-acquired pathogens from prior room occupants.

To evaluate the effectiveness of ultraviolet-C (UV-C) disinfection as an adjunct to standard chlorine-based disinfectant terminal room cleaning in reducing transmission of hospital-acquired multidrug-resistant organisms (MDROs) from a prior room occupant. A retrospective cohort study was conducted to compare rates of MDRO transmission by UV-C status from January 1, 2016, through December 31, 2018. Acute-care, single-patient hospital rooms at 6 hospitals within an academic healthcare system in Pennsylvania. Transmission of hospital-acquired MDRO infection was assessed in patients subsequently assigned to a single-patient room of a source occupant with carriage of 1 or more MDROs on or during admission. Acquisition of 5 pathogens was compared between exposed patients in rooms with standard-of-care chlorine-based disinfectant terminal cleaning with or without adjunct UV-C disinfection. Logistic regression analysis was used to estimate the adjusted risk of pathogen transfer with adjunctive use of UV-C disinfection. In total, 33,771 exposed patient admissions were evaluated; the source occupants carried 46,688 unique pathogens. Prior to the 33,771 patient admissions, 5,802 rooms (17.2%) were treated with adjunct UV-C disinfection. After adjustment for covariates, exposed patients in rooms treated with adjunct UV-C were at comparable risk of transfer of any pathogen (odds ratio, 1.06; 95% CI, 0.84-1.32; P = .64). Our analysis does not support the use of UV-C in addition to post-discharge cleaning with chlorine-based disinfectant to lower the risk of prior room occupant pathogen transfer.

Sampling for SARS-CoV-2 Aerosols in Hospital Patient Rooms.

Evidence varies as to how far aerosols spread from individuals infected with SARS-CoV-2 in hospital rooms. We investigated the presence of aerosols containing SARS-CoV-2 inside of dedicated COVID-19 patient rooms. Three National Institute for Occupational Safety and Health BC 251 two-stage cyclone samplers were set up in each patient room for a six-hour sampling period. Samplers were place on tripods, which each held two samplers at various heights above the floor. Extracted samples underwent reverse transcription polymerase chain reaction for selected gene regions of the SARS-CoV-2 virus nucleocapsid. Patient medical data were compared between participants in rooms where virus-containing aerosols were detected and those where they were not. Of 576 aerosols samples collected from 19 different rooms across 32 participants, 3% (19) were positive for SARS-CoV-2, the majority from near the head and foot of the bed. Seven of the positive samples were collected inside a single patient room. No significant differences in participant clinical characteristics were found between patients in rooms with positive and negative aerosol samples. SARS-CoV-2 viral aerosols were detected from the patient rooms of nine participants (28%). These findings provide reassurance that personal protective equipment that was recommended for this virus is appropriate given its spread in hospital rooms.

Family Presence Restrictions and Telemedicine Use in Neonatal Intensive Care Units during the Coronavirus Disease Pandemic.

We aimed to describe parental presence policy and telemedicine use in Japanese neonatal intensive care units (NICUs) before and during the coronavirus disease (COVID-19) pandemic. This cross-sectional study was performed through an online survey in 110 level III units from 19 November 2020 to 18 December 2020. Nurses’ evaluation of the current situation (during COVID-19) was compared with their retrospective pre-COVID-19 (December 2019) evaluation. Responses were received from 52 NICUs distributed across all regions in Japan. The median allowed parental presence time decreased from 12 h to 1 h, and 29 NICUs allowed entry of parents simultaneously during COVID-19. There was an increase in the number of units providing telemedicine through telephone and online visits during COVID-19 compared to that before COVID-19 (from 2% to 19%). The hybrid design NICUs, with 11–89% of beds in single-patient rooms, allowed a longer parental presence time in the NICUs than those with ≥90% of beds in multi-bed rooms. The number of units implementing kangaroo care decreased during COVID-19 compared to that before COVID-19. The need for telemedicine increased among Japanese NICUs to mitigate the adverse effect of parental restriction and limited physical contact due to the COVID-19 pandemic.

The cost-effectiveness of temporary single-patient rooms to reduce risks of healthcare-associated infection

The use of single rooms for patient isolation often forms part of a wider bundle to prevent certain healthcare-associated infections (HAIs) in hospitals. Demand for single rooms often exceeds what is available and the use of temporary isolation rooms may help resolve this. Changes to infection prevention practice should be supported by evidence showing that cost-effectiveness is plausible and likely. To perform a cost-effectiveness evaluation of adopting temporary single rooms into UK National Health Service (NHS) hospitals. The cost-effectiveness of a decision to adopt a temporary, single-patient, isolation room to the current infection prevention efforts of an NHS hospital was modelled. Primary outcomes are the expected change to total costs and life-years from an NHS perspective. The mean expected incremental cost per life-year gained (LYG) is £5,829. The probability that adoption is cost-effective against a £20,000 threshold per additional LYG is 93%, and for a £13,000 threshold the probability is 87%. The conclusions are robust to scenarios for key model parameters. If a temporary single-patient isolation room reduces risks of HAI by 16.5% then an adoption decision is more likely to be cost-effective than not. Our estimate of the effectiveness reflects guidelines and reasonable assumptions and the theoretical rationale is strong. Despite uncertainties about the effectiveness of temporary isolation rooms for reducing risks of HAI, there is some evidence that an adoption decision is likely to be cost-effective for the NHS setting. Prospective studies will be useful to reduce this source of uncertainty.

Transmission of COVID-19 on an Inpatient Hospital Prison Unit

Background: Prison populations have been disproportionally affected by COVID-19, partly due to challenges related to social distancing. Data on viral transmission dynamics in inpatient prison units remain limited. The Ohio State University Wexner Medical Center (OSUWMC) has a 24-bed inpatient prison unit in collaboration with the Ohio Department of Rehabilitations and Corrections (ODRC). The unit has 5 shared rooms holding 4 patients each and 4 single-patient rooms. Several cases of inpatient transmission of COVID-19 were identified on the inpatient prison unit. Methods: An IRB-approved retrospective chart review was conducted to evaluate inpatient transmission dynamics of hospital-acquired (HCA) COVID-19. All ODRC patients admitted from March 1 to April 24, 2020, were included. Patients assigned to the prison unit during their hospital stay were evaluated for potential HCA COVID-19, defined as a positive SARS-CoV-2 test ≥4 days after admission. Patient characteristics, testing data, symptoms, aerosol-generating procedures (AGPs), and room assignments were reviewed. Healthcare workers (HCWs) and correction officers (COs) working on the unit who tested positive during this period were identified. Results: In total, 142 ODRC patients were admitted during the study period and 89% had a positive SARS-CoV-2 testing prior to or during admission. Also, 61 patients (43%) were assigned to the prison unit. Moreover, 8 patients on the unit met potential HCA COVID-19 definition with 7 linked to 3 distinct clusters. Also, 7 COs had COVID-19 (outside hospital exposure) and 5 HCWs acquired COVID-19 from patient exposure on the unit. In cluster 1, 4 patients admitted to the same room developed HCA COVID-19. A symptomatic index patient not tested on admission given an atypical presentation required CPAP and frequent nebulizer treatments. In cluster 2, 1 patient from cluster 1 was transferred to another room. The new roommate subsequently developed HCA COVID-19. In cluster 3, a symptomatic correctional officer was assigned to 2 patients in a shared room; the patients later developed HCA COVID-19. Conclusions: Three patient clusters of HCA COVID-19 on a prison unit were identified. Aerosol transmission potentially played a role in cluster 1. Inpatient transmission within the unit prompted updated guidance for ODRC admissions, including universal SARS-CoV-2 admission testing, excluding patients requiring AGPs from shared rooms, and preemptive isolation for patients from an ODRC facility experiencing a COVID-19 surge. Universal testing was quickly expanded to all inpatient admissions. HCWs and COs were also linked to inpatient transmission, highlighting the importance of strict infection control practices for patient populations who cannot socially distance.Funding: NoDisclosures: None

Small quantities of respiratory syncytial virus RNA only in large droplets around infants hospitalized with acute respiratory infections

BackgroundRespiratory syncytial virus (RSV) is a major cause of respiratory tract infections in young children. The predominant transmission routes for RSV are still a matter of debate. Specifically, it remains unclear if RSV can be transmitted through the air and what the correlation is between the amount of RSV in nasopharynx samples and in the air.MethodsThe amount of RSV in the air around hospitalized RSV infected infants in single-patient rooms was quantified using a six-stage Andersen cascade impactor that collects and fractionates aerosols and droplets according to size. RSV shedding in the nasopharynx of patients was followed longitudinally by quantifying RSV RNA levels and infectious virus in nasopharyngeal aspirates. Nose and throat swabs of parents and swabs of the patient’s bedrail and a datalogger were also collected.ResultsPatients remained RSV positive during the air sampling period and infectious virus was isolated up to 9 days post onset of symptoms. In three out of six patients, low levels of RSV RNA, but no infectious virus, were recovered from impactor collection plates that capture large droplets > 7 μm. For four of these patients, one or both parents were also positive for RSV. All surface swabs were RSV-negative.ConclusionsDespite the prolonged detection of infectious RSV in the nasopharynx of patients, only small amounts of RSV RNA were collected from the air around three out of six patients, which were primarily contained in large droplets which do not remain suspended in the air for long periods of time.
