The current research on ST elevation myocardial infarction (STEMI) patients has been mostly limited to Door-to-Balloon (D-to-B) time. This study aimed to compare the effects of different hospital admission modes to on the time metrics of patients undergoing primary percutaneous coronary intervention (PPCI). It also examined the effects of these modes on in-hospital mortality and other influencing factors. The goal was to prompt healthcare facilities at all levels, including chest hospitals, the Centers for Disease Control and Prevention (CDC), and communities to take measures to enhance the treatment outcomes for patients with STEMI. A total of 1053 cases of STEMI patients admitted to Tianjin Chest Hospital from December 2016 to December 2023 and successfully underwent PPCI were selected for this study. They were divided into three groups based on the admission modes: the ambulances group (363 cases), the self-presentation group (305 cases), and the transferred group (385 cases). Multivariate logistic regression was used to explore the impact of different modes of hospital admission on the standard-reaching rate of key treatment time metrics. The results showed that the S-to-FMC time of transferred patients (OR = 0.434, 95% CI 0.316-0.596, P < 0.001) and self-presentation patients (OR = 0.489, 95% CI 0.363-0.659, P < 0.001) were more likely to exceed the standard than that of ambulance patients; The cath lab pre-activation time of self-presented patients was also less likely to meet the standard than that of ambulance patients (OR = 0.695, 95% CI 0.499-0.967, P = 0.031); D-to-W time of self-presentation patients was less likely to reach the standard than that of ambulance patients (OR = 0.323, 95% CI 0.234-0.446, P < 0.001);However, the FMC-to-ECG time of self-presentation patients was more likely to reach the standard than that of ambulance patients (OR = 2.601, 95% CI 1.326-5.100, P = 0.005). The Cox proportional hazards model analysis revealed that for ambulance patients, the time spent at each key treatment time point is shorter, leading to lower in-hospital mortality rate (HR0.512, 95% CI 0.302-0.868, P = 0.013) compared to patients admitted by other means. We found that direct arrival of STEMI patients to the PCI hospital via ambulance at the onset of the disease significantly reduces the S-to-FMC time, FMC-to-ECG time, D-to-W time, and catheterization room activation time compared to patients who self-present. This admission mode enhances the likelihood of meeting the benchmark standards for each time metric, consequently enhancing patient outcomes.

This article aims to examine the effects of weekend admission on in-hospital mortality for patients with acute myocardial infarction (AMI) in Brazil. Information from the Hospital Information System of the Unified Health System (SIH/SUS) of urgently admitted patients diagnosed with acute myocardial infarction (AMI) between 2008 and 2018 was used, made available through the Hospital Admission Authorization (AIH). Multivariable logistic regression models, controlling for observable patient characteristics, hospital characteristics and year and hospital-fixed effects, were used. The results were consistent with the existence of the weekend effect. For the model adjusted with the inclusion of all controls, the chance of death observed for individuals hospitalized on the weekend is 14% higher. Our results indicated that there is probably an important variation in the quality of hospital care depending on the day the patient is hospitalized. Weekend admissions were associated with in-hospital AMI mortality in Brazil. Future research should analyze the possible channels behind the weekend effect to support public policies that can effectively make healthcare equitable.

BACKGROUND: To predict testicular involvement in patients diagnosed with Fournier\'s gangrene (FG) using the Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score and the site other than lower limb (SIARI) score.
METHODS: The medical records of 51 patients operated for FG in our clinic between December 2012 and April 2022 were evaluated retrospectively in this study. Patients\' demographics, and laboratory test results were compared with the testisticular involvement status. Patients with testisticular involvement (n = 10) were compared with patients without testicular involvement (n = 41). The SIARI score at initial admission was analysed using logistic regression analyses for its performance in predicting testicular involvement with FG. Receiver operating characteristics (ROC) curves and the area under the receiver operating characteristic curve (AUROC) were used to evaluate its discriminating ability.
RESULTS: The SIARI score had modest performance for diagnosing testicular involvement in FG patients, with ROC analysis showing an AUROC value of 0.83 (p < 0.001). With a SIARI cut-off score of ≥ 3, the sensitivity was 90% and the specificity was 68%. For a SIARI cut-off score of ≥ 5, the sensitivity was 40% and the specificity was 97%.
CONCLUSIONS: The ability of the SIARI score to discriminate FG with testicular involvement is modest. The SIARI score should be employed cautiously as a routine diagnostic tool for the prediction of testicular involvement in FG at the initial admission. More research is needed to develop a better understanding of the relationship between the SIARI score and testicular involvement in FG.

BACKGROUND: Inappropriate utilization of higher-level health facilities and ineffective management of referral processes in resource-limited settings are becoming increasingly a concern in health care management in developing countries. This is characterized by self-referral and frequent bypassing of the nearest health facilities coupled with low formal referral mechanisms. This scenario lends itself to a situation where uncomplicated medical conditions are unnecessarily managed in a high-cost health facility. On July 1, 2021, Kenyatta National Hospital (KNH) enforced the Kenya Health Sector Referral Implementation Guidelines, 2014, which required patients to receive approval from the KNH referral office and a formal referral letter to be admitted at KNH to reduce the number of walk-ins and allow KNH to function as a referral facility as envisioned by the Kenya 2010 Constitution and KNH legal statue of 1987.
OBJECTIVE: To determine the effect of enforcing the national referral guidelines on patterns of orthopaedic admissions to the KNH. This was a pre-post intervention study. Data abstraction was done for 459 and 446 charts before and after the enforcement of the national referral guidelines, respectively.
RESULTS: Enforcement of the national referral guidelines reduced the proportion of walk-in admissions from 54.9% to 45.1%, while the proportion of facility referrals increased from 46.6% to 53.4% (p = 0.013). The percentage of non-trauma orthopaedic admissions doubled from 12.0% to 22.4% (p<0.001). There was also an increase in admissions through the Outpatient Clinic and Corporate Outpatient Clinic. The proportion of emergency admissions declined, while that of elective admissions increased. The increase in elective cases was mainly driven by the increase in female admissions with active insurance cover, tertiary education, non-trauma-related conditions and older age groups. However, the use of official formal written referral letters did not change despite the enforcement of the national referral guidelines.
CONCLUSIONS: The enforcement of the national referral guidelines reduced the proportion of walk-ins\' admissions to KNH. While the enforcement of the national referral guidelines had no effect on the use of official formal written referral letters, it did limit access and utilization of inpatient orthopedic services for young male patients with no active insurance cover and in need of emergency orthopedic care.

OBJECTIVE: To describe the change in admission rate and demographic profile of patients admitted to ICUs throughout Denmark before and during first wave of the SARS-CoV-2 pandemic.
METHODS: A register-based national observational study of all patients admitted to ICU from December 2019 until April 2020, comparing ICU admission before and after lockdown.
RESULTS: The number of admissions declined, especially in the age groups below 18 and above 70. The sex distribution and the comorbidity-level remained unchanged. The length of hospital stay prior to ICU admission increased. Overall fewer patients were admitted electively.
CONCLUSIONS: Fewer patients were admitted to ICU and waited longer for admission during the first wave of the COVID-19 pandemic.

BACKGROUND: Cardiovascular diseases are a substantial burden on healthcare systems, contributing significantly to avoidable hospital admissions. We propose a Cardiology Ambulatory Care Pathway.
METHODS: Conducted a 1 month study redirecting admission streams from primary and emergency care, into a Cardiology Ambulatory Care Hub providing triage in Hot Clinic, and access to a Multi-Modal Testing Platform.
RESULTS: 98 patients were referred to the Ambulatory Care Hub, 91 of which avoided admission. 52 patients received care in the cardiology hub, 38 of which required further testing.
CONCLUSIONS: We successfully streamlined various service streams, reducing admissions, and improving patient outcomes. Outpatient CTCA, ambulatory ECG, and echocardiography proved instrumental. We project a cost saving of £53,379 per month in bed days (£640,556 annual saving).

The advent of the SARS-CoV-2 pandemic brought unprecedented challenges to healthcare systems worldwide. As the virus spread across continents, hospitals faced a surge in patient admissions, particularly to intensive care units (ICUs). Understanding the impact of the pandemic on the sickest patients admitted to hospital is crucial for enhancing preparedness for future outbreaks. In this edition of the journal, authors from Denmark report on a register-based national observational study that sheds light on the changes in ICU admission rates and demographic profiles of patients during the initial phase of the pandemic.

BACKGROUND: Older adults are too often hospitalized from the emergency department (ED) without needing hospital care. Knowledge about rates and causes of these preventable emergency admissions (PEAs) is limited. This study aimed to assess the proportion of PEAs, the level of agreement on perceived preventability between physicians and patients, and to explore their underlying causes as perceived by patients, their relatives, and the admitting physician.
METHODS: A multi-center multi-method study at the ED of one academic and two regional hospitals in the Netherlands was performed. All patients aged > 70 years and hospitalized from the ED were consecutively sampled during a six-week period. Quantitative data regarding patient and clinical characteristics and perceived preventability of the admission were prospectively collected from the electronical medical record and analyzed using descriptive statistics. Agreement on preventability between patient, caregivers and physicians was assessed by using the Cohen\'s kappa. Underlying causes of a PEA were subsequently collected by semi-structured interviews with patients and caregivers. Physician\'s perceived causes of a PEA were collected by telephone interviews and by open-ended questions sent by email. Thematic content analysis was used to analyze the interview transcripts and email narratives.
RESULTS: Out of 773 admissions, 56 (7.2%) were deemed preventable by patients or their caregivers. Admitting physicians regarded 75 (9.7%) admissions as preventable. The level of agreement between these two groups was low with a Cohen\'s kappa score of 0.10 (p = 0.003). Perceived causes for PEAs related to six themes: (1) insufficient support at home, (2) suboptimal care in the community setting, (3) errors in hospital care, (4) time of presentation to ED and availability of resources, (5) delayed help seeking behavior, and (6) errors made by patients.
CONCLUSIONS: Our findings contribute to the existing evidence that a substantial part (almost one out of ten) of the older adults visiting the ED is perceived as unnecessary hospital care by patients, caregivers and health care providers. Findings also provide valuable insight into the causes for PEAs from a patient perspective. Further research is needed to understand why the perspectives of those responsible for hospital admission and those being admitted vary considerably.

BACKGROUND: Mounting evidence suggests that vitamin D deficiency is associated with a higher risk of many chronic non-skeletal, age-associated diseases as well as mortality.
OBJECTIVE: To determine, in older patients aged ≥ 80, the prevalence of vitamin D deficiency and its association with comorbidity, laboratory tests, length of stay and mortality within one year from blood withdrawal on admission to acute geriatrics ward.
METHODS: We retrospectively surveyed electronic hospital health records of 830 older patients. The recorded data included patient demographics (e.g., age, sex, stay duration, readmissions number, death within one year from blood withdrawal on admission), medical diagnoses, laboratory results, including 25-hydroxyvitamin D [25(OH)D], and medications. We compared the characteristics of the patients who survived to those who died within one year.
RESULTS: On admission, in 53.6% patients, vitamin D levels were lower than 50 nmol/L, and in 32%, the levels were ≤ 35 nmol/L. Persons who died were likely to be older, of male sex, were likely to be admitted for pneumonia or CHF, were likely to have lower level of albumin or hemoglobin, lower level of vitamin D or higher vitamin B12 and higher level of creatinine, were also likely to have had a lengthier hospitalization stay, a greater number of hospitalizations in the last year, a higher number of comorbidities, to have consumption of ≥5 drugs or likely to being treated with insulin, diuretics, antipsychotics, anticoagulants or benzodiazepines. Higher age, male sex, on-admission CHF, higher number of drugs, lower albumin, higher vitamin B12, vitamin D < 50 nmol/L, and consumption of antipsychotics and anticoagulants - were predictors of mortality.
CONCLUSIONS: Hypovitaminosis D is predictive of mortality in older patients within one year from hospitalization in the acute geriatric ward, but a causal relationship cannot be deduced. Nevertheless, older patients in acute care settings, because of their health vulnerability, should be considered for vitamin D testing. In the acutely ill patients, early intervention with vitamin D might improve outcomes. Accurate evaluation of mortality predictors in this age group patients may be more challenging and require variables that were not included in our study.

UNASSIGNED: The clinical impact of heart rate (HR) in heart failure with preserved ejection fraction (HFpEF) is a matter of debate. Among those with HFpEF, chronotropic incompetence (CI) has emerged as a pathophysiological mechanism linked to the severity of the disease. In this study, we sought to evaluate whether admission heart rate in acute heart failure differs along left ventricular ejection fraction (LVEF).
UNASSIGNED: We included retrospectively 3,712 consecutive patients admitted for acute heart failure (AHF) in the Cardiology department of a third level center. HR values were assessed at presentation. LVEF was assessed by transthoracic echocardiogram during the index admission and stratified into four categories: reduced ejection fraction (≤40%), mildly reduced ejection fraction (41-49%), preserved ejection fraction (50-64%) and supranormal ejection fraction (≥65%). The association between HR and LVEF was assessed by multivariate linear and multinomial regression analyses.
UNASSIGNED: The mean age of the sample was 73,9 ± 11.3 years, 1,734 (47,4%) were women, and 1,214 (33,2%), 570 (15,6%), 1,229 (33,6%) and 648 (17,7%) patients showed LVEF ≤40%, 41-49%, 50-64%, and ≥65% respectively. The median HR at admission was 95 (IQR 78-120) beats per minute and 1,653 were on atrial fibrillation (45.2%). There was an inverse relationship between HR at admission and LVEF. Lower HR was significantly associated with a higher LVEF in the whole sample (p < 0,001). This inverse relationship was found in sinus rhythm but not in patients with atrial fibrillation.
UNASSIGNED: HR at admission for AHF is a predictor of LVEF but only in patients with sinus rhythm.
