COVID-19 Vaccination in Home Health and Hospice: Barriers to Vaccination and Results From a Home Vaccination Program

Little is known about vaccination rates in home health and hospice populations. Results draw upon two separate data sources from The Visiting Nurse Association Health Group (VNAHG). Among VNAHG patients surveyed between February 2 and March 1, 202, 24% had received at least one COVID-19 vaccine. Among vaccinated patients, roughly one quarter did not travel to get the vaccine (received inpatient vaccination). They mostly traveled by car (88%), and 70% received help from a family member. Of patients who had not received a vaccine (76%), 81% were pursuing or planning to pursue obtaining a vaccine. Additionally, of those not pursuing a vaccine, 30% indicated it was because they could not get to a vaccine site. 44% of patients in the VNAHG “in home” vaccination pilot were bedbound, and 100% of patients had ambulation difficulties that make it impossible for them to leave home. All (100%) had a health care provider(s) recommended they get the vaccine. Only 38% have internet access. A quarter tried to call to schedule a vaccine, but only one was able to speak to someone. 40% of the patients attempted to get a COVID-19 vaccine prior to enrollment in the program. Most patients (81%) did not have someone available to assist with their transportation to get vaccinated, and most indicated difficulty securing an appointment. Many indicated severe traveling difficulties (requiring oxygen, needing ambulance transport). These findings highlight the high barriers for homebound patients, and the need and value of clinicians traveling to provide in-home vaccines.

Investigating age and regional effects on the relation between the incidence of heat-related ambulance transport and daily maximum temperature or WBGT

Background Although age and regional climate are considered to have effects on the incidence ratio of heat-related illness, quantitative estimation of age or region on the effect of occurring temperature for heat stroke is limited. Methods By utilizing data on the number of daily heat-related ambulance transport (HAT) in each of three age groups (7–17, 18–64, 65 years old, or older) and 47 prefectures in Japan, and daily maximum temperature (DMT) or Wet Bulb Globe Temperature (DMW) of each prefecture for the summer season, the effects of age and region on heat-related illness were studied. Two-way ANOVA was used to analyze the significance of the effect of age and 10 regions in Japan on HAT. The population-weighted average of DMT or DMW measured at weather stations in each prefecture was used as DMT or DMW for each prefecture. DMT or DMW when HAT is one in 100,000 people (T1 and W1, respectively) was calculated for each age category and prefecture as an indicator of heat acclimatization. The relation between T1 or W1 and average DMT or DMW of each age category and prefecture were also analyzed. Results HAT of each age category and prefecture was plotted nearly on the exponential function of corresponding DMT or DMW. Average R2 of the regression function in 47 prefectures in terms of DMW was 0.86, 0.93, and 0.94 for juveniles, adults, and elderly, respectively. The largest regional difference of W1 in 47 prefectures was 4.5 and 4.8 °C for juveniles and adults, respectively between Hokkaido and Tokyo, 3.9 °C for elderly between Hokkaido and Okinawa. Estimated W1 and average DMT or DMW during the summer season for 47 prefectures was linearly related. Regarding age difference, the regression line showed that W1 of the prefecture for DMW at 30 °C of WBGT was 31.1 °C, 32.4 °C, and 29.8 °C for juveniles, adults, and elderly, respectively. Conclusions Age and regional differences affected the incidence of HAT. Thus, it is recommended that public prevention measures for heat-related disorders take into consideration age and regional variability.

COVID-19 pandemic modifies temperature and heat-related illness ambulance transport association in Japan: a nationwide observational study

Background During the COVID-19 pandemic, several illnesses were reduced. In Japan, heat-related illnesses were reduced by 22% compared to pre-pandemic period. However, it is uncertain as to what has led to this reduction. Here, we model the association of maximum temperature and heat-related illnesses in the 47 Japanese prefectures. We specifically examined how the exposure and lag associations varied before and during the pandemic. Methods We obtained the summer-specific, daily heat-related illness ambulance transport (HIAT), exposure variable (maximum temperature) and covariate data from relevant data sources. We utilized a stratified (pre-pandemic and pandemic), two-stage approach. In each stratified group, we estimated the 1) prefecture-level association using a quasi-Poisson regression coupled with a distributed lag non-linear model, which was 2) pooled using a random-effects meta-analysis. The difference between pooled pre-pandemic and pandemic associations was examined across the exposure and the lag dimensions. Results A total of 321,655 HIAT cases was recorded in Japan from 2016 to 2020. We found an overall reduction of heat-related risks for HIAT during the pandemic, with a wide range of reduction (10.85 to 57.47%) in the HIAT risk, across exposure levels ranging from 21.69 °C to 36.31 °C. On the contrary, we found an increment in the delayed heat-related risks during the pandemic at Lag 2 (16.33%; 95% CI: 1.00, 33.98%). Conclusion This study provides evidence of the impact of COVID-19, particularly on the possible roles of physical interventions and behavioral changes, in modifying the temperature-health association. These findings would have implications on subsequent policies or heat-related warning strategies in light of ongoing or future pandemics.

Sex Equitable Prehospital Stroke Triage Using Symptom Severity and Teleconsultation

Objectives: We aimed to determine whether there are sex differences in prehospital accuracy of the Stockholm Stroke Triage System (SSTS) to predict large artery occlusion (LAO) stroke, and endovascular thrombectomy (EVT), and whether clinical characteristics differ between men and women undergoing “code stroke” ambulance transport.Materials and Methods: This prospective observational study collected data between October 2017 and October 2018. We included 2,905 patients, transported as “code stroke,” by nurse-staffed ground ambulance, to a Stockholm Region hospital. Exclusion criteria were private or helicopter transport, onset outside Stockholm, and in-hospital stroke. We compared overall accuracy, sensitivity, specificity, positive and negative predictive values, and clinical characteristics between sexes.Results: No significant sex differences in SSTS predictive performance for LAO or EVT were found, overall accuracy for LAO 87.3% in women vs. 86.7% in men. Women were median 4 years older and more frequently had stroke mimics (46.2 vs. 41.8%). Women more commonly had decreased level of consciousness (14.0 vs. 10.2%) and moderate-to-severe motor symptoms (by 2.7–3.8 percentage points), and less commonly limb ataxia (7.2 vs. 9.7%).Conclusions: The SSTS had equal predictive performance for LAO and EVT among men and women, despite minor sex differences in the clinical characteristics in patients undergoing ambulance transport for suspected stroke.

Implementation and Findings On A One-Minute Sit-Stand Test for Prehospital Triage in Patients With Suspected COVID-19 - A Pilot Project

Introduction: During the initial Coronavirus Disease 2019 (COVID-19) pandemic wave, sparse personal protection equipment made telephone triage of suscpeted COVID-19 patients for ambulance transport necessary. To spare resources, stable patients were often treated and released on-scene, but reports from Italy suggested that some later detoriated. We implemented a prehospital sit-stand test to identify patients in risk for detoriation. Methods The test was implemented as part of a new guideline in stable suspected COVID-19 patients younger than 70 years with no risk factors for serious disease triaged by general practitioners to ambulance response in the Central Denmark Region. Data were collected from April 6th to July 6th 2020. This was a two-part study evaluating guideline adherence and results of the sit-stand test. The primary outcome of each separate part was 1) the proportion of patients sit-stand tested before treat-and-released and 2) the proportion of patients treated with oxygen within 7 days among patients decompensating and not decompensation during the test. Results Data on 156 patients triaged to ambulance response by general practioners were analysed. In total 86/156 (55%) were tested with the sit-stand test, among these 30/86 (47%) were either older than 70 or had risk factors for serious disease. Of those treated and released, 50/52 (96%) were tested. In total, 17/86 (20%) decompensated during the test and of these, 9/17 (53%) were treated with oxygen compared to 2/69 (3%) in patients who did not decompensate (p < 0.001). This difference was only significant in the elderly group of patients with risk factors for serious disease. 10/156 (6%) of patients had a positive COVID-19-test. Conclusion The sit-stand test was implemented in 96% of patients treated and released on-scene, but was also used in elderly patients with risk factors for serious disease. Decompensation was observed in 20% of patients and was associated with oxygen treatment within 7 days – but only in the elderly group of patients with risk factors for serious disease. These findings are hypotheses-generating and suggest that physical exercise testing may be usefull for decision making in emergency settings.

Cross-sectional study of the ambulance transport between healthcare facilities with medical support via telemedicine: Easy, effective, and safe tool

Background Feasibility and safety of ambulance transport between healthcare facilities with medical support exclusively via telemedicine are unknown. Methods This was a retrospective study with a single telemedicine center reference for satellite emergency departments of the same hospital. The study population was all critically ill patients admitted to one of the peripheral units from November 2016 to May 2020 and who needed to be transferred to the main building. Telemedicine-assisted transportation was performed by an emergency specialist. The inclusion criteria included patients above the age of 15 and initial stabilization performed at the emergency department. Unstable, intubated, ST-elevation myocardial infarction and acute stroke patients were excluded. There was a double-check of safety conditions by the nurse and the remote doctor before the ambulance departure. The primary endpoint was the number of telemedicine-guided interventions during transport. Results 2840 patients were enrolled. The population was predominantly male (53.2%) with a median age of 60 years. Sepsis was the most prevalent diagnosis in 28% of patients, followed by acute coronary syndromes (8.5%), arrhythmia (6.7%), venous thromboembolism (6.1%), stroke (6.1%), acute abdomen (3.6%), respiratory distress (3.3%), and heart failure (2.5%). Only 22 (0.8%) patients required telemedicine-assisted support during transport. Administration of oxygen therapy and analgesics were the most common recommendations made by telemedicine emergency physicians. There were no communication problems in the telemedicine-assisted group. Conclusions Telemedicine-assisted ambulance transportation between healthcare facilities of stabilized critically ill patients may be an option instead of an onboard physician. The frequency of clinical support requests by telemedicine is minimal, and most evaluations are of low complexity and easily and safely performed by trained nurses.

Health facility preparedness of maternal and neonatal health services: a survey in Jumla, Nepal

Background Over the past 20 years, Nepal has seen major improvements in childhood and maternal survival. In 2015, the Nepalese government introduced a new federal political structure. It is unclear how this has affected the health system, and particularly, maternal and child health care. Hence, this study aims to describe and analyse health facility preparedness in the light of the federalization process with regards to providing appropriate and timely maternal and neonatal health services. Methods A descriptive cross-sectional study was conducted in Jumla district, Nepal in 2019 covering all 31 state health facilities (HF) to assess the availability of maternal and neonatal health services including appropriate workforce and access to essential medicines. Tests of association between demographic factors and the probability of a facility experiencing a shortage of essential medicine within the last 3 months were also conducted as exploratory procedures. Results Out ot 31 HFs, more than 90% of them had all their staff positions filled. Most facilities (n = 21) had experienced shortages of essential medicines within the past 3 months. The most common out of stock medicine were: Amoxicillin (n = 10); paracetamol (n = 10); Vitamin A (n = 7); and Metronidazole (n = 5). Twenty-two HFs had referred maternal and newborn cases to a higher centre within the past 12 months. However, more worryingly, twenty HFs or their catchment communities did not have emergency ambulance transport for women and newborns. Conclusion HFs reported better staffing levels than levels of available drugs. HFs should be supported to meet required minimal standards such as availability of essential medicines and the provision of emergency ambulance transport for women and newborns.

Risk of methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE) acquisition during ambulance transport: A retrospective propensity-score–matched cohort analysis

Objective: To estimate the relative risk (RR) of developing methicillin-resistant Staphylococcus aureus (MRSA) or vancomycin-resistant Enterococcus (VRE) colonization or infection within 30 days of ambulance transport. Methods: We performed a retrospective cohort study of patients with a principal diagnosis of chest pain presenting to our emergency department (ED) over a 4-year period. Patients were included if they presented from and were discharged to nonhealthcare locations without being admitted. Encounters were stratified by arrival mechanism: ambulance versus private vehicle. We performed propensity score matching and multivariable logistic regression to estimate the RR for the primary outcome. Results: In total, 321,229 patients had ED encounters during the study period. After applying inclusion criteria and propensity score matching, there were 11,324 patients: 3,903 in the ambulance group and 7,421 in the unexposed group. Among them, 12 patients (0.11%) had the outcome of interest, including 9 (0.08%) with MRSA and 3 (0.03%) with VRE. The 30-day prevalence of MRSA or VRE was larger in the ambulance group than in the unexposed group: 8 (0.20%) and 4 (0.05%), respectively (P = .02). Patients who presented to the ED via ambulance were almost 4 times more likely to have MRSA or VRE within 30 days of their encounter (RR, 3.72; 95% CI, 1.09–12.71; P = .04). Conclusions: Our cohort study is the first to demonstrate an association between ambulance exposure and pathogen incidence, representing the first step in evaluating medical-transport–associated infection burden to eventually develop interventions to address it.
