Mobility scores as a predictor of length of stay in general surgery: a prospective cohort study

Association between reduced physical performance measures and short-term consequences after major emergency abdominal surgery: a prospective cohort study

BACKGROUND

Major emergency abdominal surgery is associated with high morbidity with outcomes worse than for similar elective surgery, including complicated physical recovery, increased need for rehabilitation, and prolonged hospitalisation.

PURPOSE

To investigate whether low physical performance test scores were associated with an increased risk of postoperative complications, and, furthermore, to investigate the feasibility of postoperative performance tests in patients undergoing major emergency abdominal surgery. We hypothesize that patients with low performance test scores suffer more postoperative complications.

METHODS

The study is a prospective observational cohort study including all patients who underwent major abdominal surgery at the Department of Surgery at Zealand University Hospital between 1st March 2017 and 31st January 2019. Patients were evaluated with De Morton Mobility Index (DEMMI) score, hand grip strength, and 30-s chair-stand test.

RESULTS

The study included 488 patients (median age 69, 50.6% male). Physiotherapeutic evaluation including physical performance tests with DEMMI and hand grip strength in the immediate postoperative period were feasible in up to 68% of patients undergoing major emergency abdominal surgery. The 30-s chair-stand test was less viable in this population; only 21% of the patients could complete the 30-s chair-stand test during the postoperative period. In logistic regression models low DEMMI score (< 40) and ASA classification and low hand grip strength (< 20 kg for women, < 30 kg for men were independent risk factors for the development of postoperative severe complications Clavien-Dindo (CD) grade ≥ 3.

CONCLUSIONS

In patients undergoing major emergency surgery low performance test scores (DEMMI and hand grip strength), were independently associated with the development of significant postoperative complications CD ≥ 3.

Preoperative characteristics are associated with increased likelihood of low early postoperative mobility after adult spinal deformity surgery

BACKGROUND CONTEXT

Low early postoperative mobility (LEPOM) has been shown to be associated with increased length of hospital stay, complication rates, and likelihood of nonhome discharge. However, few studies have examined preoperative characteristics associated with LEPOM in adult spinal deformity (ASD) patients.

PURPOSE

To investigate which preoperative patient characteristics may be associated with LEPOM after ASD surgery.

DESIGN

Retrospective review.

PATIENT SAMPLE

Included were 86 ASD patients with fusion of ≥5 levels for whom immediate-postoperative AM-PAC Basic Mobility Inpatient Short Form (6-Clicks) scores had been obtained.

OUTCOME MEASURES

The primary outcome of this study was the likelihood of LEPOM, defined as an AM-PAC score ≤15, which is associated with inability to stand for more than 1 minute.

METHODS

Significant cutoffs for preoperative characteristics associated with LEPOM were determined via threshold linear regression. Multivariable logistic regression was used to assess the impact of preoperative characteristics on the likelihood of LEPOM.

RESULTS

LEPOM was recorded in 38 patients (44.2%). Threshold regression identified the following cutoffs to be associated with LEPOM: preoperative Patient Reported Outcomes Measurement Information System (PROMIS) scores of ≥68 for Pain, <28.3 for Physical Function, and ≥63.4 for Anxiety; preoperative Oswestry disability index (ODI) score of ≥60; and body mass index (BMI) of ≥35.2. On multivariate analysis, preoperative PROMIS scores of ≥68 for Pain (odds ratio [OR] 5.3, confidence interval [CI] 1.2-22.8, p=.03), <28.3 for Physical Function (OR 10.1, CI 1.8-58.2, p=.01), and ≥63.4 for Anxiety (OR 4.7, CI 1.1-20.8, p=.04); preoperative ODI score ≥60 (OR 38.8, CI 4.0-373.6, p=.002); BMI ≥35.2 (OR 14.2, CI 1.3-160.0, p=.03), and male sex (OR 5.4, CI 1.2-23.7, p=.03) were associated with increased odds of LEPOM.

CONCLUSIONS

Preoperative PROMIS Pain, Physical Function, and Anxiety scores; ODI score; BMI; and male sex were associated with LEPOM. Several of these characteristics are modifiable risk factors and thus may be candidates for optimization before surgery.

C1q and mobility score in predicting sarcopenia in an Australian cohort of cancer surgery patients

BACKGROUND

Sarcopenia has been shown to have significant adverse health outcomes in a range of patient populations. Particularly, sarcopenic patients having cancer surgery are a unique group who demonstrate poorer post-operative outcomes. Currently, the gold standard in diagnosing sarcopenia is through the use of computed tomography. However, the widespread use of imaging to diagnose patients with sarcopenia is neither cost-effective nor practical. Identifying a serum biomarker or a simple mobility scoring system as an alternative diagnostic tool may aid in identifying more patients at risk of sarcopenia. C1q, a novel biomarker, has previously been shown to correlate with sarcopenia. Similarly, we sought to explore whether mobility scores may provide a useful surrogate marker for sarcopenia.

METHODS

This was a prospective cohort study of patients who presented for colorectal cancer surgery between the dates of 6/10/2016 and 4/10/2017 at John Hunter Hospital. Computed tomography was utilized to calculate the psoas area at the L3 spinal level. Pre-operative blood samples were obtained for C1q analysis and de Morton Mobility Index (DEMMI) was also performed.

RESULTS

A total of 51 patients were included in the study. The median age of the patients were 69 years old. We did not demonstrate a correlation between serum C1q and DEMMI scores with psoas area.

CONCLUSION

Our findings suggest that neither C1q nor DEMMI scores are correlated with psoas area in a colorectal cancer population.

Length of Stay in Patients Undergoing Tracheoplasty: A NSQIP Study

BACKGROUND

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 in patient undergoing tracheoplasty.

METHODS

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 considered as prolonged and was utilized for bivariate analysis of demographic, comorbidity, and operative characteristics. LOS was utilized as a continuous variable for multivariate linear regression analysis.

RESULTS

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 being defined at 10 days. On bivariate analysis of associated comorbidities, patients with prolonged LOS were more commonly obese (72.4% vs. 53.1%, p = 0.009), diabetic (37.9% vs. 16.5%, p < 0.001), dyspneic (58.6% vs. 40.7%, p = 0.016), and had chronic steroid use (25.9% vs. 12.9%, p = 0.018). Multivariable logistic regression analysis demonstrated significant associations between prolonged LOS and both chronic obstructive pulmonary disorder (COPD) (OR: 3.43, p = 0.020) and chronic steroid use (OR: 3.81, p = 0.018).

CONCLUSIONS

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.

The LAPLAP study: a randomized placebo-controlled clinical trial assessing postoperative functional recovery using intraperitoneal local anaesthetic in laparoscopic colorectal surgery

AIM

Postoperative pain remains a major factor in recovery from colorectal resection. There is increasing interest in opioid-sparing analgesia, and intraperitoneal local anaesthetic (IPLA) has recently been shown to be useful in minor laparoscopic and open colorectal procedures. The aim of this study was to evaluate the impact of IPLA on functional recovery following major laparoscopic surgery. In this controlled trial, mobility, as measured by the De Morton Mobility Index (DEMMI), was used as a surrogate for postoperative functional recovery.

METHOD

Patients undergoing laparoscopic colorectal resection were randomized either to continuous ropivacaine (0.2% at 4-6 ml/h) or to saline (0.9%) which were administered via intraperitoneal catheter for 3 days postoperatively. Results were analysed in a double-blind manner. DEMMIs were assessed on postoperative days 1, 2, 3, 7 and 30, and data on pain, opioid consumption, gut and respiratory function, length of stay (LOS) and complications were recorded.

RESULTS

Ninety-six patients were recruited. There was no difference in primary outcome (i.e., functional recovery) between IPLA and placebo groups. Opioid consumption and LOS were similar between groups, and no differences were found for any secondary outcome measure. There were no adverse events related to ropivacaine.

CONCLUSION

Infusional intraperitoneal local anaesthetic appears to be safe but does not improve functional recovery or analgesic consumption following elective laparoscopic colorectal surgery, in the setting of an established enhanced recovery programme.

DEMMI Scores, Length of Stay, and 30-Day Readmission of Acute Geriatric Patients in Denmark: A Cross-Sectional Observational Study with Longitudinal Follow-Up

The aims of this study are to describe the mobility of acute geriatric patients, the length of stay, and to characterise patients who were readmitted within 30 days based on the De Morton Mobility Index (DEMMI). A cross-sectional observational study with longitudinal follow-up was conducted in the period from 1 March 2016 to 31 August 2016. Inclusion criteria were acute geriatric patients hospitalised for a minimum of 24 h. Of the 418 patients hospitalised during the study period, 246 (59%) participated in this study (44% male, median age 83 years [70; 94]). For patients in an acute geriatric department, the median DEMMI score was 41 and the mean score was 39.95. Patients with a DEMMI score ≤40 show a significantly lower Barthel 100 index, lower 30 s. sit-to-stand scores and were significantly more likely to be bedridden or, amongst those not bedridden, to use a mobility aid. Lower DEMMI scores were associated with longer admissions. DEMMI seems to have the ability to predict discharge within one week. There was no significant association between a lower DEMMI score and higher risk for 30-day readmission. Further research is needed to determine whether the DEMMI is suitable for identifying the patient's need for further rehabilitation following the discharge.
