Effects of a medical team coordinator on length of hospital stay.

OBJECTIVE: To determine the effect of a medical team coordinator (MTC) on the length of stay in a teaching hospital. DESIGN: Randomized controlled trial. SETTING: Two of four general medical clinical teaching units (CTUs). PATIENTS: Patients admitted to the CTUs between July and October 1990 except those who were admitted directly to an intensive care unit or whose death was expected within 48 hours. The 267 patients were randomly assigned to receive either standard medical care or standard medical care plus MTC services. INTERVENTION: The MTC was a baccalaureate nurse whose role was to facilitate administrative tasks such as discharge planning, to coordinate tests and procedures, and to collect and collate patient information. MAIN OUTCOME MEASURES: Length of hospital stay. A subgroup of 40 patients was asked to complete a brief survey on medical care information and satisfaction. RESULTS: The MTC intervention reduced the mean length of stay by 1.97 days (p less than or equal to 0.04, 95% confidence interval [CI] 1.02 to 2.92 days). Subanalysis by diagnostic group revealed that most of this effect was in an ill-defined group of disorders. In the survey more patients in the MTC group than in the other group reported being satisfied with their medical care (89% v. 62%; p less than or equal to 0.05, 95% CI 2% to 52%). CONCLUSIONS: The services of an MTC help to reduce the length of hospital stay for some groups of patients. Further research is necessary to examine which components of the MTC intervention are most effective and in what conditions.     

The effect of hospital-acquired infection with Clostridium difficile on length of stay in hospital

Background:

The effect of hospital-acquired infection with Clostridium difficile on length of stay in hospital is not yet fully understood. We determined the independent impact of hospital-acquired infection with C. difficile on length of stay in hospital.

Methods:

We conducted a retrospective observational cohort study of admissions to hospital between July 1, 2002, and Mar. 31, 2009, at a single academic hospital. We measured the association between infection with hospital-acquired C. difficile and time to discharge from hospital using Kaplan–Meier methods and a Cox multivariable proportional hazards regression model. We controlled for baseline risk of death and accounted for C. difficile as a time-varying effect.

Results:

Hospital-acquired infection with C. difficile was identified in 1393 of 136 877 admissions to hospital (overall risk 1.02%, 95% confidence interval [CI] 0.97%–1.06%). The crude median length of stay in hospital was greater for patients with hospital-acquired C. difficile (34 d) than for those without C. difficile (8 d). Survival analysis showed that hospital-acquired infection with C. difficile increased the median length of stay in hospital by six days. In adjusted analyses, hospital-acquired C. difficile was significantly associated with time to discharge, modified by baseline risk of death and time to acquisition of C. difficile. The hazard ratio for discharge by day 7 among patients with hospital-acquired C. difficile was 0.55 (95% CI 0.39–0.70) for patients in the lowest decile of baseline risk of death and 0.45 (95% CI 0.32–0.58) for those in the highest decile; for discharge by day 28, the corresponding hazard ratios were 0.74 (95% CI 0.60–0.87) and 0.61 (95% CI 0.53–0.68).

Interpretation:

Hospital-acquired infection with C. difficile significantly prolonged length of stay in hospital independent of baseline risk of death.Infection with Clostridium difficile is associated with poor outcomes for patients.^1,2 Previous work has determined that, regardless of baseline risk of death, for every 10 patients that acquire C. difficile in hospital, 1 patient will die.³ Clostridium difficile is also associated with increased health care costs.^1,2 One of the primary mechanisms by which C. difficile increases costs is by increasing the length of time patients spend in hospital.⁴Previous studies have found that hospital-acquired infection with C. difficile increases a patient’s length of stay by one to three weeks.^2,5–8 However, these estimates are potentially biased. First, previous studies have not accounted for the time-varying nature of this infection. Hospital-acquired infection with C. difficile is a variable that is unknown at admission but occurs during the stay in hospital.^3,9 Treating time-varying variables as fixed in time-to-event analyses leads to “time-dependent bias” and may exaggerate the association between a risk factor and the time to the event of interest. Second, our previous work³ has shown that the risk of hospital-acquired infection with C. difficile significantly increases as a patient’s baseline risk of death increases; it is, therefore, important to account for risk of death at admission when investigating the association between hospital-acquired C. difficile and length of stay.Because of the importance of an accurate estimate of the impact of C. difficile, we conducted a retrospective observational cohort study to determine the independent association between hospital-acquired infection with C. difficile and length of stay in hospital. We accounted for each patient’s risk of death upon admission and the variable amount of time patients spent in hospital before acquiring C. difficile.     

Implementation of a fast-track clinical pathway decreases postoperative length of stay and hospital charges for liver resection

A fast-track clinical pathway is designed to streamline patient care delivery and maximize cost effectiveness. It has decreased postoperative length of stay (LOS) and hospital charges for many surgical procedures. However, data on clinical pathways after liver surgery are sparse. This study examined whether use of a fast-track clinical pathway for patients undergoing elective liver resection affected postoperative LOS and hospital charges. A fast-track clinical pathway was developed and implemented by a multidisciplinary team for patients undergoing liver resection. Between July, 2007 and May, 2008, a total of 117 patients underwent elective liver resection: the fast-track clinical pathway (education of patients and families, earlier oral feeding, earlier discontinuation of intravenous fluid, no drains or nasogastric tubes, early ambulation, use of a urinary catheter for less than 24 h and planned discharge 6 days after surgery) was studied prospectively in 56 patients (postpathway group). These patients were compared with the remainder who had usual care (prepathway group). Outcome measures were postoperative LOS, perioperative hospital charges, intraoperative and postoperative complications, mortality, and readmission rate. Among all patients, 69 (59%) had complicating diseases and/or a history of surgery and 24 patients belonged to American Society of Anesthesiologists grade III–IV. Compared with the prepathway group, the postpathway group had a significantly shorter postoperative LOS (7 vs. 11 days, P < 0.01). The average perioperative hospital charges were RMB 26,626 for patients in the prepathway group and only RMB 21,004 for those in the postpathway group (P < 0.05), with no differences in intraoperative and postoperative complications (P = 0.814), mortality (P = 0.606), and readmission rate (P = 0.424). Implementation of the fast-track clinical pathway is an effective and safe method for reducing postoperative LOS and hospital charges for high-risk patients undergoing elective liver resection. The result supports the further development of fast-track clinical pathways for liver surgical procedures.     

Predictors for length of hospital stay in patients with community-acquired Pneumonia: Results from a Swiss Multicenter study

ABSTRACT: BACKGROUND: Length of hospital stay (LOS) in patients with community-acquired pneumonia (CAP) is variable and directly related to medical costs. Accurate estimation of LOS on admission and during follow-up may result in earlier and more efficient discharge strategies. METHODS: This is a prospective multicenter study including patients in emergency departments of 6 tertiary care hospitals in Switzerland between October 2006 and March 2008. Medical history, clinical data at presentation and health care insurance class were collected. We calculated univariate and multivariate cox regression models to assess the association of different characteristics with LOS. In a split sample analysis, we created two LOS prediction rules, first including only admission data, and second including also additional inpatient information. RESULTS: The mean LOS in the 875 included CAP patients was 9.8 days (95%CI 9.3-10.4). Older age, respiratory rate >20pm, nursing home residence, chronic pulmonary disease, diabetes, multilobar CAP and the pneumonia severity index class were independently associated with longer LOS in the admission prediction model. When also considering follow-up information, low albumin levels, ICU transfer and development of CAP-associated complications were additional independent risk factors for prolonged LOS. Both weighted clinical prediction rules based on these factors showed a high separation of patients in Kaplan Meier Curves (p logrank <0.001 and <0.001) and a good calibration when comparing predicted and observed results. CONCLUSIONS: Within this study we identified different baseline and follow-up characteristics to be strong and independent predictors for LOS. If validated in future studies, these factors may help to optimize discharge strategies and thus shorten LOS in CAP patients.     

Two factors that can increase the length of hospital stay of patients with dementia

ObjectivesPatients with dementia are at greater risk of a long hospital stay and this is associated with adverse outcomes. The aim of this service evaluation was to identify variables most predictive of increased length of hospital stay amongst patients with dementia.Methods/DesignWe conducted a retrospective analysis on a cross-sectional hospital dataset for the period January–December 2016. Excluding length of stay less than 24 h and readmissions, the sample comprised of 1133 patients who had a dementia diagnosis on record.ResultsThe highest incidence rate ratio for length of stay in the dementia sample was: (a) discharge to a care home (IRR: 2.443, 95% CI 1.778–3.357), (b) falls without harm (IRR: 2.486, 95% CI 2.029–3.045).ConclusionsBased on this dataset, we conclude that improvements made to falls prevention strategies in hospitals and discharge planning procedures can help to reduce the length of stay for patients with dementia.     

Trends in Extinction Risk for Imperiled Species in Canada

Protecting and promoting recovery of species at risk of extinction is a critical component of biodiversity conservation. In Canada, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) determines whether species are at risk of extinction or extirpation, and has conducted these assessments since 1977. We examined trends in COSEWIC assessments to identify whether at-risk species that have been assessed more than once tended to improve, remain constant, or deteriorate in status, as a way of assessing the effectiveness of biodiversity conservation in Canada. Of 369 species that met our criteria for examination, 115 deteriorated, 202 remained unchanged, and 52 improved in status. Only 20 species (5.4%) improved to the point where they were ‘not at risk’, and five of those were due to increased sampling efforts rather than an increase in population size. Species outcomes were also dependent on the severity of their initial assessment; for example, 47% of species that were initially listed as special concern deteriorated between assessments. After receiving an at-risk assessment by COSEWIC, a species is considered for listing under the federal Species at Risk Act (SARA), which is the primary national tool that mandates protection for at-risk species. We examined whether SARA-listing was associated with improved COSEWIC assessment outcomes relative to unlisted species. Of 305 species that had multiple assessments and were SARA-listed, 221 were listed at a level that required identification and protection of critical habitat; however, critical habitat was fully identified for only 56 of these species. We suggest that the Canadian government should formally identify and protect critical habitat, as is required by existing legislation. In addition, our finding that at-risk species in Canada rarely recover leads us to recommend that every effort be made to actively prevent species from becoming at-risk in the first place.     

Intraoperative intravascular volume optimisation and length of hospital stay after repair of proximal femoral fracture: randomised controlled trial.

OBJECTIVES: To assess whether intraoperative intravascular volume optimisation improves outcome and shortens hospital stay after repair of proximal femoral fracture. DESIGN: Prospective, randomised controlled trial comparing conventional intraoperative fluid management with repeated colloid fluid challenges monitored by oesophageal Doppler ultrasonography to maintain maximal stroke volume throughout the operative period. SETTING: Teaching hospital, London. SUBJECTS: 40 patients undergoing repair of proximal femoral fracture under general anaesthesia. INTERVENTIONS: Patients were randomly assigned to receive either conventional intraoperative fluid management (control patients) or additional repeated colloid fluid challenges with oesophageal Doppler ultrasonography used to maintain maximal stroke volume throughout the operative period (protocol patients). MAIN OUTCOME MEASURES: Time declared medically fit for hospital discharge, duration of hospital stay (in acute bed; in acute plus long stay bed), mortality, perioperative haemodynamic changes. RESULTS: Intraoperative intravascular fluid loading produced significantly greater changes in stroke volume (median 15 ml (95% confidence interval 10 to 21 ml)) and cardiac output (1.2 l/min (0.1 to 2.3 l/min)) than in the conventionally managed group (-5 ml (-10 to 1 ml) and -0.4 l/min (-1.0 to 0.2 l/min)) (P < 0.001 and P < 0.05, respectively). One protocol patient and two control patients died in hospital. In the survivors, postoperative recovery was significantly faster in the protocol patients, with shorter times to being declared medically fit for discharge (median 10 (9 to 15) days v 15 (11 to 40) days, P < 0.05) and a 39% reduction in hospital stay (12 (8 to 13) days v 20 (10 to 61) days, P < 0.05). CONCLUSIONS: Proximal femoral fracture repair constitutes surgery in a high risk population. Intraoperative intravascular volume loading to optimal stroke volume resulted in a more rapid postoperative recovery and a significantly reduced hospital stay.     

Mammals at rescue centres in the Czech Republic: Trends in intake and outcome,causes of admission,length of stay and release rate

Rescue centres in the Czech Republic care for injured, young uninjured, and otherwise physically damaged wild animals that are temporarily or permanently incapable of looking after themselves without assistance or incapable of surviving in the wild. We evaluated the numbers of mammals admitted to 37 rescue centres in the Czech Republic in a ten year period from 2011 to 2020, the causes leading to the admission of these mammals to rescue centres, their outcomes and their length of stay at rescue centres. In total, 73,499 mammals were admitted to the Czech rescue centres in the monitored period, with an increasing trend being found in the number of admissions (rSp = 0.9030, p < 0.05). The mammals admitted in the largest numbers were Chiroptera (39.36%), primarily the common pipistrelle (Pipistrellus pipistrellus), and Insectivora (35.85%), of which the largest proportion was made up of European hedgehogs (Erinaceus europaeus). Although according to the IUCN classification only 0.26% of admitted animals belonged among Endangered or Critically Endangered species, according to the Czech legislation, 47.21% of admitted mammals belonged to species in varying degrees of endangerment in this area. The most frequent reasons for admission were the admission of young (33.18%) with differences between the Orders - the highest number of admitted young of Rodentia (72.66% of all admitted Rodentia) and the lowest number of young of Chiroptera (2.74%). Of all mammals admitted to rescue centres, 45.83% were released back into the wild, 24.52% died at rescue centres, and 9.50% were euthanized. The highest release rate was achieved in Chiroptera (74.60%) especially those that suffered from malnutrition (63.09% of all admitted Chiroptera due to malnutrition). The length of stay was longest in young Artiodactyla released back to the wild (median 87 days). The data obtained from rescue centres provide an overview of the numbers and species of animals admitted and the outcome of their rehabilitation. Since almost half of mammals admitted could not be returned to the wild, it is also important to determine correctly which individuals should be treated and what is the most efficient use of resources for wildlife rehabilitation.     

Variation in hospital stay after inguinal herniorrhaphy.

A study was carried out of 1086 men aged 16-65 inclusive who were admitted under nine consultants to eight hospitals in Wessex for elective repair of an inguinal hernia. The mean postoperative stay was 5.7 +/- SD 2.7 days. For different consultants operating at any one hospital the mean postoperative stays were similar, whereas for consultants who operated at more than one hospital they were significantly different. The postoperative stay was also significantly related to the size of the hospital, development of postoperative complications, time spent on the waiting list, type of repair used, bilateral herniorrhapy, and the use of convalescent facilities. The hospital therefore appears to exercise a greater influence in determining the mean postoperative stay than does the individual consultant.     

Trends in ectopic pregnancy in Canada.

The incidence in Canada of one complication of sexually transmitted disease, ectopic pregnancy, was examined by age group for the years 1971 through 1980 by means of hospital statistics provided by Statistics Canada. The denominator was "reported pregnancies"--the total of live births, stillbirths, legal abortions and ectopic pregnancies in a given year. In 1980, 4123 ectopic pregnancies (9.3/1000 reported pregnancies) were reported, a 63% increase from 1970. The incidence had increased in each age stratum. This trend may be related to increasing rates of gonococcal infection and of hospitalization for pelvic inflammatory disease and lends confirmation to data from other countries that relate the increase in the rate of ectopic pregnancy to rising rates of sexually transmitted disease.     

Shortening hospital stay for psychiatric care: effect on patients and their families

A one-year cohort of patients from a defined catchment area with acute functional disorders were allocated at random to brief care (experimental group) or standard care (control group) in hospital to examine the effect of shortening hospital stay on the clinical and social functioning of patients and the distress abnormal functioning caused to others. A total of 127 patients were interviewed on entry to the study, and 106 were followed up. The brief care group had significantly shorter mean and median lengths of stay than the control group, but there was no difference between the groups in the number of days spent in hospital during subsequent admissions. The groups were well matched for clinical and social variables. Rates of improvement over 13 weeks were essentially the same by all measures of outcome, including the Present State Examination and Patient''s Behaviour Assessment Scale, which was developed for the study to measure deterioration in behaviour and social functioning and adverse effects and distress on others. There was no difference between the two groups in burden to the community supporting services, social security requirements, or GP attendances. Improvement rates were nearly identical on all measures within and across diagnostic subgroups. Brief care resulted in a 33% reduction in average length of stay compared with the year before but was associated with a corresponding increase in day hospital use. The short-stay policy continued the year after the study finished.The findings confirm the value of shortening hospital stay and improving day care facilities for most localities.
