Effect of Instrumented Spine Surgery on Length of Stay.

Total joint arthroplasty studies have identified that surgeries that take place later in the week have a longer length of stay compared with those earlier in the week. This has not been demonstrated i... All instrumented spine surgeries in 2019 at a single academic tertiary center were retrospectively reviewed. Patients were categorized for surgical day and discharge disposition to home or a rehabilit... Seven hundred six patients were included in the analysis. Excluding Saturday, there were no differences in length of stay based on the day of surgery. Age older than 75 years, female, American Society... Day of surgery does not affect length of stay in instrumented spine surgeries. Discharge to a rehabilitation facility, however, did increase the length of stay as did age older than 75 years, higher A...

Perioperative risk factors impact on intensive care unit length of stay (ICU length of stay) in oral squamous cell carcinoma.

The trend in postoperative care for free flap patients is to deescalate from routine ICU admission into a specialty recovery unit. This study aims to investigate the predictive parameters in a routine... All patients who underwent ablative surgery for OSCC with free flap reconstruction and were managed in the ICU were included in this study. The primary outcome was ICU-length of stay. Perioperative, o... The study included 136 homogeneous patients, with a mean ICU length of stay of 4.5 (± 4.43 day). Patients with pre-operative positive renal dysfunction (P = 0.004), peripheral vascular disease (P < 0.... Patients with perioperative severe renal dysfunction, peripheral vascular disease, postoperative complication or high NYHA class are prone to have a significantly longer ICU length of stay. Several fa...

Frailty, length of stay and cost in hip fracture patients.

A hip fracture causes high morbidity and mortality. Frailty is associated with adverse outcomes and increased costs. Frailty measured using the Hospital Frailty Risk Score (HFRS) is associated with hi... Hip fractures account for an increasing number of hospital admissions around the world and are associated with high rates of morbidity and mortality. Frailty is increasingly recognized to be associate... A retrospective analysis was performed on 1014 patients ≥ 60 years who presented with a hip fracture between January 2016 to June 2020. Each patient was classified into HFRS low, intermediate or high ... Median total hospitalization costs were significantly higher in the highest HFRS (SGD$22,432) patients as compared to intermediate (SGD$18,759) and low HFRS (SGD$15,671) patients. The difference betwe... Frailty is associated with a marked increase in total costs in hip fracture patients. HFRS proved useful in estimating LOS and outcomes for older patients with hip fractures....

Length of Stay in Patients Undergoing Tracheoplasty: A NSQIP Study.

Prolonged length of stay (LOS) has been associated with increased morbidity and resource utilization in various surgical procedures. We aim to determine factors associated with increased hospital stay... The 2012-2018 National Surgical Quality Improvement Program (NSQIP) database was queried for patients undergoing tracheoplasty. Patient LOS was the primary clinical outcome. A LOS >75th percentile was... A total of 252 patients were queried. The majority of patients were female (67.5%), white (82.4%), and over the age of 65 (77.0%). Patients had a median LOS of 7 days with the 75th percentile cutoff b... This study elucidates factors associated with prolonged LOS in patients undergoing tracheoplasty. Patients with COPD and chronic steroid use were significantly associated with prolonged LOS.... 4 Laryngoscope, 133:1938-1942, 2023....

Genetic Testing and Hospital Length of Stay in Neonates With Epilepsy.

We evaluated changes in genetic testing for neonatal-onset epilepsy and associated short-term outcomes over an 8-year period among a cohort of patients in the neonatal intensive care unit (NICU) at a ... Our primary outcome was a change in length of stay (LOS) after 2018. We also ascertained severity of illness with the Neonatal Sequential Organ Failure Assessment (nSOFA), type and result of genetic t... Fifty-three infants with genetic testing were included; 20 infants were tested after 2018. A total of 4160 infants in the NICU without genetic testing were used as reference. In the genetic testing gr... In this cohort, changes in genetic testing for neonatal-onset epilepsy were associated with shorter LOS that was not explained by changes in severity of illness, birth weight, or the average LOS in th...

[Laboratories as predictors of length of hospital stay in patients with pneumonia].

There are several factors that influence the length of hospital stay (LoHS) in patients with community-acquired pneumonia (CAP). There is currently no study in the literature that correlates laborator... To find the association of laboratory parameters with the LoHS in patients with community-acquired pneumonia.... An observational, prospective, longitudinal, and controlled study was conducted in the emergency room of a secondary level hospital.... The mean time of LoHS in patients with CAP was 6.6 ± 3.0 days. The parameters of laboratory of monocytes, basophils and segmented neutrophils presented a correlation (Spearman rho) of 0.363, 0.364 and... LoHS in patients with CAP is related to the counting of monocytes, basophils, and neutrophils at the time of the hospital admittance and it was increased in patients with SAH and patients with COPD....

Laparoscopy in high-risk emergency general surgery reduces intensive care stay, length of stay and mortality.

Emergency general surgery patients undergoing laparoscopic surgery are at reduced risk of mortality and may require reduced length of critical care stay. This study investigated the effect of laparosc... Data were retrieved for all patients entered into the NELA database between 2013 and 2018. Only high-risk surgical patients (P-POSSUM predicted mortality risk of ≥ 5%) were included. Patients undergoi... A total of 66,517 high-risk patients received emergency major abdominal surgery. A laparoscopic procedure was attempted in 6998 (10.5%); of these, the procedure was competed laparoscopically in 3492 (... The results of this study suggest that in patients at high risk of post-operative mortality, laparoscopic emergency bowel surgery leads to a reduced length of critical care stay, overall length of sta...

Factors associated with an extended length of stay in the pediatric burn patient.

The Center for Medicaid and Medicare Services predicts the length of stay for pediatric burn patients based on several variables. However, many patients exceed their anticipated length. This study loo... We conducted a retrospective chart review of 535 pediatric burn patients admitted to our academic hospital from January 2018 to December 2020. 405 patients met inclusion criteria. Data were collected ... Average patient age was 3.36 years. 72.3% were treated for scald burns. Average length of stay was 13.5 days. 20.5% (n = 83) of patients exceeded their predicted length of stay. In comparing patients ... Twenty percent of pediatric burn patients had a longer length of stay than predicted by the Center for Medicaid and Medicare Services. Many factors were strongly associated with a longer-than-predicte...

Interventions on modifiable clinical risk factors, such as morning CEA scheduling and manageme...

Association of Prophylaxis and Length of Stay With Venous Thromboembolism in Abdominopelvic Surgery.

Extended venous thromboembolism prophylaxis (eVTEp) is recommended for select patients who have undergone major abdominopelvic surgery to prevent postdischarge venous thromboembolism (pdVTE). Criteria... A retrospective cohort study of patients undergoing abdominopelvic surgery from January 2016 to February 2020 was performed using data from the Michigan Surgical Quality Collaborative. pdVTE was the m... A total of 45,637 patients underwent abdominopelvic surgery. Of which, 3063 (6.71%) were prescribed eVTEp. Two hundred eighty-five (0.62%) had pdVTE. Of the 285, 59 (21%) patients received eVTEp, whil... pdVTE was associated with increasing LOS but not with other VTE risk factors after propensity score matching. Current guidelines for eVTEp do not include LOS. Our findings suggest that LOS >5 d should...
