Original articleClinical outcomes in medical outliers admitted to hospital with heart failure☆
Introduction
Many factors influence the prognosis and the length of stay of patients admitted to hospital. Many of these factors require a skilled practitioner to identify them. Patients with coronary heart disease, pulmonary embolism, chronic kidney disease, anaemia, hypoalbuminemia, cognitive impairment, or cancer have a higher morbidity than people without these conditions when they are admitted to hospital [1], [2], [3], [4], [5], [6], [7], [8], [9], [10], [11], [12], [13], [14], [15]. Studying these factors allows the design of programs that improve the quality of hospital care.
Each hospital department manages one ward in which their patients are admitted. If there is a lack of beds within this ward, the department can choose between admitting more patients per ward or, if there are free beds in other wards of the hospital, placing them there. This latter option may not always be the best solution because patients located outside the ward may interfere with the activities of staff (e.g., medical staff doing the ward round, nursing staff caring for patients whose conditions may be different to those they are used to managing) and with the activities of the wards where they are placed (e.g., reducing elective admissions to surgical wards, increasing waiting lists) [16], [17]. In some hospitals, elective surgical patients are brought in overnight rather than on the day of admission to “protect” the bed [18].
Studies focusing on the differences in disease management between different specialists have been reported [6], [19], [20], [21], [22], [23], but publications about the influence of location in patient progress are lacking.
The aim of this study is to determine if location influences the progress and prognosis of patients.

Design
This was a retrospective cohort study using data from the minimum basic data set (MBDS), discharge summaries, and test records from La Princesa University Hospital (LPUH; a public centre with approximately 500 beds) in Madrid, Spain.
Participants
Patients discharged from the Department of Internal Medicine during 2006 with the All Patients Diagnosis-Related Group (AP-DRG) 544 (congestive heart failure and cardiac arrhythmia with major complications or comorbidity) were included. Patients who were admitted to
Results
243 patients met the inclusion criteria; none were excluded. 66 (27%) patients were male; the mean age was 82.2 ± 8.1 years; 109 (45%) patients were medical outliers. Table 1 shows the baseline characteristics of patients according to medical outlier status. Among these measures, we found a significantly different distribution in “admission at the weekend or bank holiday” that was more frequent in the medical outliers cohort (34% v 22%; p = 0.045).
Medical outliers had a longer stay in hospital (11.8
Discussion
Attention is immediately drawn to the significant difference in the LOS between the two cohorts (2.6 days, 95% confidence interval (CI) 0.6–4.7). We could hypothesize that medical outliers have a longer stay in the hospital because they suffer from more complications, but no significant differences were found in the patients studied.
We consider that the longer stay in hospital of medical outliers was not related to worse care, but to worse management of hospital resources. Clinicians usually
Learning points
- •
It is usual, as a solution to the lack of beds in a hospital ward, to place patients in other wards, which belong to other departments. These patients are often called “medical outliers”.
- •
Medical outliers admitted to hospital with heart failure have a longer stay than those admitted to the department's ward, but we did not observe an increased prevalence of mortality, intra-hospital morbidity, or readmission in our study population.
- •
Reducing the number of these patients will improve the

Length of hospital stay among oldest-old patients in acute geriatric ward
2021, Archives of Gerontology and GeriatricsCitation Excerpt :Many of these factors require a skilled practitioner to identify them. Patients with coronary heart disease, pulmonary embolism, chronic kidney disease, anemia, hypoalbuminemia, cognitive impairment, or cancer have a higher morbidity than patients without these conditions when they are admitted to hospital (Alameda and Suárez, 2009). We have not found studies focusing on oldest-old inpatients aged ≥90 years old.

A review of inpatient ward location and the relationship to Medical Emergency Team calls
2017, International Emergency NursingCitation Excerpt :The concern towards overcrowding pertains to the inability of clinical staff to implement models of care or clinical pathways that have been proven to be effective for specific conditions. As a result, the fragmentation of care has been shown to occur and led to medication errors and increased length of stay for outlier patients (Alameda and Suárez, 2009; Perimal-Lewis et al., 2013; Stowell et al., 2013). Evidence for a causal link between the length of hospital stay, critical incidents, mortality and readmission of outlier patients is lacking and this relationship reported in commentaries is primarily anecdotal (Perimal-Lewis et al., 2013).
