Evaluating the impact of frailty on periprocedural adverse events and mortality among patients with GI bleeding

Frailty Predicts Mortality and Procedural Performance in Patients With Non-Variceal Upper Gastrointestinal Bleeding

Introduction

Nonvariceal upper gastrointestinal bleeding (NVUGIB) is a common cause of hospitalization in the United States, with approximately 400 000 admissions annually and a 5%-10% mortality rate. This study aimed to evaluate frailty's impact on NVUGIB outcomes.

Methods

We utilized the 2019 National Readmission Database (NRD) to identify adult patients (≥ 18 years) admitted with a principal diagnosis of NVUGIB using ICD-10-CM codes. NVUGIB hospitalizations were stratified by frailty using the hospital frailty risk score (HFRS) of 5 or more as the cut-off for frailty. Multivariate regression analyses were conducted to analyze the outcomes. STATA 14.2 was used for statistical testing.

Results

Among 218 647 NVUGIB admissions, 99 892 (45.69%) were frail. Frail patients were older, more often female, and had higher comorbidity burdens. They showed significantly greater in-hospital mortality (adjusted odds ratio [aOR] 5.64, 95% CI 4.94-6.44; p < 0.001), acute kidney injury (5.85), respiratory failure (6.93), septic shock (40.94), hemorrhagic shock (2.64), vasopressor use (4.36), mechanical ventilation (6.04), and ICU admission (5.41). Although frail patients had higher odds of esophagogastroduodenoscopy (EGD) with intervention (1.04; p < 0.001), they were less likely to receive EGD within 24 h (0.75; p < 0.001). They also had higher odds of rebleeding (1.18; p < 0.001) and radioembolization (2.69; p < 0.001). Length of stay increased by 2.30 days, total charges rose by $28 518, discharge to rehabilitation was more frequent (3.12; p < 0.01), and 30-day readmission was higher (15.24% vs. 11.43%, HR 1.16; p < 0.001).

Conclusion

Frailty independently predicts worse clinical outcomes and increased resource use in NVUGIB. Recognizing frailty may improve risk stratification and guide more tailored management strategies for this high-risk population.

Understanding the role of nutritional status on the outcomes of nonvariceal upper gastrointestinal bleeding: Findings from a retrospective cohort analysis

BACKGROUND & AIMS

Nonvariceal upper gastrointestinal bleeding (NVUGIB) is a common cause of hospitalization worldwide. Malnutrition, on the other hand, varies in prevalence and closely correlates with age and comorbidities. Though malnutrition is linked to poor outcomes generally, its impact on NVUGIB patients remains unexplored.

METHODS

Using the National Readmission Database (NRD) from 2016 to 2020, we employed the International Classification of Diseases, 10th revision, Clinical Modifications (ICD-10-CM) codes to identify adult patients (aged ≥18 years) admitted with a principal diagnosis of NVUGIB. We further stratified NVUGIB hospitalizations based on the presence and severity of malnutrition. Utilizing a multivariate regression model, we assessed the impact of malnutrition on NVUGIB outcomes. STATA 14.2 was utilized for statistical analysis.

RESULTS

Out of the 742,592 adult patients admitted with NVUGIB, 76,603 (10.32 %) had malnutrition, categorized as mild to moderate (3.01 %), severe (4.00 %), and malnutrition of unspecified severity (3.29 %). After adjusting for confounding variables, all-cause in-hospital mortality due to NVUGIB was significantly higher in malnourished patients, corresponding to the severity of malnutrition (adjusted odds ratio [aOR] 1.83 & 3.52 in mild-moderate malnutrition and severe malnutrition respectively; P < 0.01). Similarly, malnutrition was associated with progressively higher odds of acute kidney injury (aOR 1.39 & 1.54 for mild-moderate and severe malnutrition, respectively), septic shock (aOR 2.41 & 5.12), hemorrhagic shock (aOR 1.71 & 2.16), and intensive care unit (ICU) admission (aOR 2.00 & 2.97), all increasing with malnutrition severity (P < 0.01). Procedural analysis showed lower odds of diagnostic EGD (aOR 0.95 & 0.92), EGD within 24 h (aOR 0.75 & 0.67), and overall EGD (aOR 0.80 & 0.66) in malnourished patients, but higher odds of rebleeding requiring repeat EGD (aOR 1.12 & 1.19) and radioembolization (aOR 2.04 & 2.75), both rising with malnutrition severity (P < 0.01). Finally, resource utilization estimated by total hospitalization charges, length of stay, discharge to rehabilitation facilities (aOR 1.99 & 2.66), and 30-day readmission rates (aOR 1.29 & 1.38) were also significantly higher among patients with malnutrition (P < 0.01).

CONCLUSION

Malnutrition exacerbates the outcomes of NVUGIB including higher in-hospital mortality rates, morbidity and resource utilization. Early identification and targeted management of malnutrition in NVUGIB patients are crucial to reducing adverse outcomes and optimizing healthcare resources.

Biliary drainage in palliative and curative intent European patients with hilar cholangiocarcinoma and malignant hilar obstruction: a retrospective single center analysis

BACKGROUND AND AIMS

Relief of cholestasis in hilar cholangiocarcinoma is commonly undertaken in both curative and palliative treatment plans. There are numerous open questions with regard to the ideal biliary drainage strategy - including what constitutes clinical success (CS). In the existing data, curative patients and patients from the Western world are underrepresented.

PATIENTS AND METHODS

We performed a retrospective analysis of patients with complex malignant hilar obstruction (Bismuth-Corlette II and higher) due to cholangiocarcinoma who underwent biliary drainage at a German referral center between 2010 and 2020. We aimed to define CS and complication rates and directly compare outcomes in curative and palliative patients.

RESULTS

56 curative and 72 palliative patients underwent biliary drainage. In patients with curative intent, CS was achieved significantly more often regardless of what definition of CS was applied (e.g., total serum bilirubin (TSB) < 2 mg/dl: 66.1% vs. 27.8%, p = < 0.001, > 75% reduction of TSB: 57.1% vs. 29.2%, p = 0.003). This observation held true only when subgroups with the same Bismuth-Corlette stage were compared. Moreover, palliative patients experienced a significantly greater percentage of adverse events (33.3% vs. 12.5%, p = 0.01). Curative intent treatment and TSB at presentation were predictive factors of CS regardless of what definition of CS was applied. The observed CS rates are comparable to published studies involving curative patients, but inferior to reported CS rates in palliative series mostly from Asia.

CONCLUSIONS

Biliary drainage in complex malignant hilar obstruction due to cholangiocarcinoma is more likely to be successful and less likely to cause adverse events in curative patients compared to palliative patients.

Management of Portal Hypertension in the Older Patient

PURPOSE OF THIS REVIEW

Aging is a process of physiological slowing, reduced regenerative capacity and inability to maintain cellular homeostasis. World Health Organisation declared the commencement of population aging globally, largely attributed to improvement in the healthcare system with early diagnosis and effective clinical management. Liver ages similar to other organs, with reduction in size and blood flow. In this review we aim to evaluate the effect of aging in liver disease.

RECENT FINDINGS

Aging causes dysregulation of major carbohydrate, fat and protein metabolism in the liver. Age is a major risk factor for liver fibrosis accelerated by sinusoidal endothelial dysfunction and immunological disharmony. Age plays a major role in patients with liver cirrhosis and influence outcomes in patients with portal hypertension. Transient elastography may be an useful tool in the assessment of portal hypertension. Hepatic structural distortion, increased vascular resistance, state of chronic inflammation, associated comorbidities, lack of physiological reserve in the older population may aggravate portal hypertension in patients with liver cirrhosis and may result in pronounced variceal bleed. Cut-offs for other non-invasive markers of fibrosis may differ in the elderly population. Non-selective beta blockers initiated at lower dose followed by escalation are the first line of therapy in elderly patients with cirrhosis and portal hypertension, unless contraindicated. Acute variceal bleed in the elderly cirrhotic patients can be life threatening and may cause rapid exsanguination due to poor reserve and associated comorbidities. Vasoactive drugs may be associated with more adverse reactions. Early endoscopy may be warranted in the elderly patients with acute variceal bleed. Role of TIPS in the elderly cirrhotics discussed. Management of portal hypertension in the older population may pose significant challenges to the treating clinician.

Utilization of Machine Learning to Model Important Features of 30-day Readmissions following Surgery for Metastatic Spinal Column Tumors: The Influence of Frailty

STUDY DESIGN

Retrospective cohort study.

OBJECTIVE

The aim of this study was to determine the relative importance and predicative power of the Hospital Frailty Risk Score (HFRS) on unplanned 30-day readmission after surgical intervention for metastatic spinal column tumors.

METHODS

All adult patients undergoing surgery for metastatic spinal column tumor were identified in the Nationwide Readmission Database from the years 2016 to 2018. Patients were categorized into 3 cohorts based on the criteria of the HFRS: Low(<5), Intermediate(5-14.9), and High(≥ 15). Random Forest (RF) classification was used to construct predictive models for 30-day patient readmission. Model performance was examined using the area under the receiver operating curve (AUC), and the Mean Decrease Gini (MDG) metric was used to quantify and rank features by relative importance.

RESULTS

There were 4346 patients included. The proportion of patients who required any readmission were higher among the Intermediate and High frailty cohorts when compared to the Low frailty cohort (Low:33.9% vs. Intermediate:39.3% vs. High:39.2%, P < .001). An RF classifier was trained to predict 30-day readmission on all features (AUC = .60) and architecturally equivalent model trained using only ten features with highest MDG (AUC = .59). Both models found frailty to have the highest importance in predicting risk of readmission. On multivariate regression analysis, Intermediate frailty [OR:1.32, CI(1.06,1.64), P = .012] was found to be an independent predictor of unplanned 30-day readmission.

CONCLUSION

Our study utilizes machine learning approaches and predictive modeling to identify frailty as a significant risk-factor that contributes to unplanned 30-day readmission after spine surgery for metastatic spinal column metastases.

Impact of frailty on endoscopic retrograde cholangiopancreatography outcomes in nonagenarians: A United States national experience

BACKGROUND

Endoscopic retrograde cholangiopancreatography (ERCP) is an essential therapeutic tool for biliary and pancreatic diseases. Frail and elderly patients, especially those aged ≥ 90 years are generally considered a higher-risk population for ERCP-related complications.

AIM

To investigate outcomes of ERCP in the Non-agenarian population (≥ 90 years) concerning Frailty.

METHODS

This is a cohort study using the 2018-2020 National Readmission Database. Patients aged ≥ 90 were identified who underwent ERCP, using the international classification of diseases-10 code with clinical modification. Johns Hopkins's adjusted clinical groups frailty indicator was used to classify patients as frail and non-frail. The primary outcome was mortality, and the secondary outcomes were morbidity and the 30 d readmission rate related to ERCP. We used univariate and multivariate regression models for analysis.

RESULTS

A total of 9448 patients were admitted for any indications of ERCP. Frail and non-frail patients were 3445 (36.46%) and 6003 (63.53%) respectively. Indications for ERCP were Choledocholithiasis (74.84%), Biliary pancreatitis (9.19%), Pancreatico-biliary cancer (7.6%), Biliary stricture (4.84%), and Cholangitis (1.51%). Mortality rates were higher in frail group [adjusted odds ratio (aOR) = 1.68, P = 0.02]. The Intra-procedural complications were insignificant between the two groups which included bleeding (aOR = 0.72, P = 0.67), accidental punctures/lacerations (aOR = 0.77, P = 0.5), and mechanical ventilation rates (aOR = 1.19, P = 0.6). Post-ERCP complication rate was similar for bleeding (aOR = 0.72, P = 0.41) and post-ERCP pancreatitis (aOR = 1.4, P = 0.44). Frail patients had a longer length of stay (6.7 d vs 5.5 d) and higher mean total charges of hospitalization ($78807 vs $71392) compared to controls (P < 0.001). The 30 d all-cause readmission rates between frail and non-frail patients were similar (P = 0.96).

CONCLUSION

There was a significantly higher mortality risk and healthcare burden amongst nonagenarian frail patients undergoing ERCP compared to non-frail. Larger studies are warranted to investigate and mitigate modifiable risk factors.

Tailoring follow-up endoscopy in patients with severe oesophagitis

Objective

We aimed to investigate the clinical utility of follow-up oesophagogastroduodenoscopy (OGD2) in patients with severe oesophagitis (Los Angeles grades C or D) through evaluating the yield of Barrett's oesophagus (BO), cancer, dysplasia and strictures. Second, we aimed to determine if the Clinical Frailty Scale (CFS) may be used to identify patients to undergo OGD2s.

Design/method

Patients in NHS Lothian with an index OGD (OGD1) diagnosis of severe oesophagitis between 1 January 2014 and 31 December 2015 were identified. Univariate analysis identified factors associated with grade. Patients were stratified by frailty and a diagnosis of stricture, cancer, dysplasia and BO.

Results

In total 964 patients were diagnosed with severe oesophagitis, 61.7% grade C and 38.3% grade D. The diagnostic yield of new pathology at OGD2 was 13.2% (n=51), new strictures (2.3%), dysplasia (0.5%), cancer (0.3%) and BO (10.1%). A total of 140 patients had clinical frailty (CFS score ≥5), 88.6% of which were deceased at review (median of 76 months). In total 16.4% of frail patients underwent OGD2s and five new pathologies were diagnosed, none of which were significantly associated with grade. Among non-frail patients at OGD2, BO was the only pathology more common (p=0.010) in patients with grade D. Rates of cancer, dysplasia and strictures did not vary significantly between grades.

Conclusion

Our data demonstrate that OGD2s in patients with severe oesophagitis may be tailored according to clinical frailty and only be offered to non-frail patients. In non-frail patients OGD2s have similar pick-up rates of sinister pathology in both grades of severe oesophagitis.

Hospital Frailty Risk Score and Healthcare Resource Utilization After Surgery for Primary Spinal Intradural/Cord Tumors

OBJECTIVE

The Hospital Frailty Risk Score (HFRS) is a metric that measures frailty among patients in large national datasets using ICD-10 codes. While other metrics have been utilized to demonstrate the association between frailty and poor outcomes in spine oncology, none have examined the HFRS. The aim of this study was to investigate the impact of frailty using the HFRS on complications, length of stay, cost of admission, and discharge disposition in patients undergoing surgery for primary tumors of the spinal cord and meninges.

METHODS

A retrospective cohort study was performed using the Nationwide Inpatient Sample database from 2016 to 2018. Adult patients undergoing surgery for primary tumors of the spinal cord and meninges were identified using ICD-10-CM codes. Patients were categorized into 2 cohorts based on HFRS score: Non-Frail (HFRS<5) and Frail (HFRS≥5). Patient characteristics, treatment, perioperative complications, LOS, discharge disposition, and cost of admission were assessed.

RESULTS

Of the 5955 patients identified, 1260 (21.2%) were Frail. On average, the Frail cohort was nearly 8 years older (P < .001) and experienced more postoperative complications (P = .001). The Frail cohort experienced longer LOS (P < .001), a higher rate of non-routine discharge (P = .001), and a greater mean cost of admission (P < .001). Frailty was found to be an independent predictor of extended LOS (P < .001) and non-routine discharge (P < .001).

CONCLUSION

Our study is the first to use the HFRS to assess the impact of frailty on patients with primary spinal tumors. We found that frailty was associated with prolonged LOS, non-routine discharge, and increased hospital costs.

Frailty predicts mortality in patients with upper gastrointestinal bleed: a prospective cohort study

BACKGROUND AND AIM

Evidence on the impact of frailty in patients with upper gastrointestinal bleed (UGIB) is limited. This study aims to define the role of frailty as defined by Canadian Study of Health and Aging clinical frailty scale (CSHA-CFS) in predicting mortality in UGIB.

METHODS

A prospective single-center cohort study was conducted over 21 months on all consecutive patients with UGIB. Data on demographics, lab parameters, Glasgow Blatchford score, CSHA-CFS, Charlson Comorbidity Index, and AIMS65 score was recorded. The primary outcome was all-cause inpatient mortality. The secondary outcomes were all-cause 30-day mortality, 30-day rebleeding, 30-day readmission, hospital length of stay (LoS), intensive care unit (ICU) admission, need for repeat endoscopy, and need for blood transfusion. The data were evaluated using univariate and multivariate analysis.

RESULTS

There were 298 eligible patients, of which 63% were males, median age was 68 years, 44% were from non-English-speaking background, and 72% had major comorbidities. The all-cause inpatient and 30-day mortality were 9.4% and 10.7%, respectively. In the multivariate analysis, CHSA-CFS was the independent predictor of all-cause inpatient mortality (OR 1.66; 95% CI 1.13-2.143; P = 0.010) and all-cause 30-day mortality (OR 1.83; 95% CI 1.26-2.67; P = 0.002). CHSA-CFS was not a significant predictor of 30-day rebleed, 30-day readmission, ICU admission, hospital LoS, or need for blood transfusion.

CONCLUSION

Frailty is an important independent predictor of mortality in patients with UGIB. Frailty assessment can guide clinical decision making and allow targeting of health-care resource (Australia/New Zealand Clinical Trial Registry number: ACTRN12622000821796).

Prevalence and Influence of Frailty on Hospital Outcomes After Surgical Resection of Spinal Meningiomas

OBJECTIVE

Frailty has been shown to affect patient outcomes after medical and surgical interventions. The Hospital Frailty Risk Score (HFRS) is a growing metric used to assess patient frailty using International Classification of Diseases, Tenth Revision codes. The goal of this study was to investigate the impact of frailty, assessed by HFRS, on health care resource utilization and outcomes in patients undergoing surgery for spinal meningiomas.

METHODS

A retrospective cohort study was performed using the 2016-2019 National Inpatient Sample database. Adult patients with benign or malignant spinal meningiomas, identified using International Classification of Diseases, Tenth Revision, Clinical Modification codes, were stratified by HFRS: low frailty (HFRS <5) and intermediate-high frailty (HFRS ≥5). Patient demographics, hospital characteristics, comorbidities, procedural variables, adverse events, length of stay (LOS), discharge disposition, and cost of admission were assessed. Multivariate regression analysis was used to identify predictors of increased LOS, discharge disposition, and cost.

RESULTS

Of the 3345 patients, 530 (15.8%) had intermediate-high frailty. The intermediate-high cohort was significantly older (P < 0.001). More patients in the intermediate-high cohort had ≥3 comorbidities (P < 0.001). In addition, a greater proportion of patients in the intermediate-high cohort experienced ≥1 perioperative adverse events (P < 0.001). Intermediate-high patients experienced greater mean LOS (P < 0.001) and accrued greater costs (P < 0.001). A greater proportion of intermediate-high patients had nonroutine discharges (P < 0.001). On multivariate analysis, increased HFRS (≥5) was independently associated with extended LOS (adjusted odds ratio [aOR], 3.04; P < 0.001), nonroutine discharge (aOR, 1.98; P = 0.006), and increased costs (aOR, 2.39; P = 0.004).

CONCLUSIONS

Frailty may be associated with increased health care resource utilization in patients undergoing surgery for spinal meningiomas.

Total Abdominal Colectomy Versus Diverting Loop Ileostomy and Antegrade Colonic Lavage for Fulminant Clostridioides Colitis: Analysis of the National Inpatient Sample 2016-2019

BACKGROUND

When surgery is indicated for fulminant Clostridioides difficile infection (CDI), total abdominal colectomy (TAC) is the most common approach. Diverting loop ileostomy (DLI) with antegrade colonic lavage has been introduced as a colon-sparing surgical approach. Prior analyses of National Inpatient Sample (NIS) data suggested equivalent postoperative outcomes between groups but did not evaluate healthcare resource utilization. As such, we aimed to analyze a more recent NIS cohort to compare these two approaches in terms of both postoperative outcomes and healthcare resource utilization.

METHODS

A retrospective analysis of the NIS from 2016 to 2019 was conducted. The primary outcome was postoperative in-hospital morbidity. Secondary outcomes included postoperative in-hospital mortality, system-specific postoperative complications, total admission cost, and length of stay (LOS). Univariable and multivariable regressions were utilized to compare the two operative approaches.

RESULTS

In total, 886 patients underwent TAC and 409 patients underwent DLI with antegrade colonic lavage. Adjusted analyses demonstrated no difference between groups in postoperative in-hospital morbidity (aOR 0.96, 95%CI 0.64-1.44, p = 0.851) or in-hospital mortality (aOR 1.15, 95%CI 0.81-1.64, p = 0.436). Patients undergoing TAC experienced significantly decreased total admission cost (MD $79,715.34, 95%CI 133,841-25,588, p = 0.004) and shorter postoperative LOS (MD 4.06 days, 95%CI 6.96-1.15, p = 0.006).

CONCLUSIONS

There are minimal differences between TAC and DLI with antegrade colonic lavage for fulminant CDI in terms of postoperative morbidity and mortality. Healthcare resource utilization, however, is significantly improved when patients undergo TAC as evidenced by clinically important decreases in total admission cost and postoperative LOS.

Higher Hospital Frailty Risk Score is associated with increased complications and healthcare resource utilization after endovascular treatment of ruptured intracranial aneurysms

AIM

To use the Hospital Frailty Risk Score (HFRS) to investigate the impact of frailty on complication rates and healthcare resource utilization in patients who underwent endovascular treatment of ruptured intracranial aneurysms (IAs).

METHODS

A retrospective cohort study was performed using the 2016-2019 National Inpatient Sample database. All adult patients (≥18 years) undergoing endovascular treatment for IAs after subarachnoid hemorrhage were identified using ICD-10-CM codes. Patients were categorized into frailty cohorts: low (HFRS <5), intermediate (HFRS 5-15) and high (HFRS >15). Patient demographics, adverse events, length of stay (LOS), discharge disposition, and total cost of admission were assessed. Multivariate logistic regression analysis was used to identify independent predictors of prolonged LOS, increased cost, and non-routine discharge.

RESULTS

Of the 33 840 patients identified, 7940 (23.5%) were found to be low, 20 075 (59.3%) intermediate and 5825 (17.2%) high frailty by HFRS criteria. The rate of encountering any adverse event was significantly greater in the higher frailty cohorts (low: 59.9%; intermediate: 92.4%; high: 99.2%, p<0.001). There was a stepwise increase in mean LOS (low: 11.7±8.2 days; intermediate: 18.7±14.1 days; high: 26.6±20.1 days, p<0.001), mean total hospital cost (low: $62 888±37 757; intermediate: $99 670±63 446; high: $134 937±80 331, p<0.001), and non-routine discharge (low: 17.3%; intermediate: 44.4%; high: 69.4%, p<0.001) with increasing frailty. On multivariate regression analysis, a similar stepwise impact was found in prolonged LOS (intermediate: OR 2.38, p<0.001; high: OR 4.49, p<0.001)], total hospital cost (intermediate: OR 2.15, p<0.001; high: OR 3.62, p<0.001), and non-routine discharge (intermediate: OR 2.13, p<0.001; high: OR 4.17, p<0.001).

CONCLUSIONS

Our study found that greater frailty as defined by the HFRS was associated with increased complications, LOS, total costs, and non-routine discharge.

Hospital Frailty Risk Score Predicts Adverse Events and Readmission Following a Ventriculoperitoneal Shunt Surgery for Normal Pressure Hydrocephalus

OBJECTIVE

The aim of this study was to evaluate the impact of a Hospital Frailty Risk Score (HFRS) on unplanned readmission and health care resource utilization in normal pressure hydrocephalus (NPH) patients undergoing a ventriculoperitoneal (VP) shunt surgery.

METHODS

A retrospective cohort study was performed using the 2016-2019 Nationwide Readmission Database. All NPH patients (≥60 years) undergoing a VP shunt surgery were identified using ICD-10-CM diagnostic and procedural codes. Patients were dichotomized into 2 cohorts as follows: Low HFRS (<5) and Intermediate-High HFRS (≥5). A multivariate logistic regression analysis was then used to identify independent predictors of adverse event (AE) and 30- and 90-day readmission.

RESULTS

Of 13,262 patients, 4386 (33.1%) had an Intermediate-High HFRS score. A greater proportion of the Intermediate-High HFRS cohort experienced at least one AE (1.9 vs. 22.1, P < 0.001). The Intermediate-High HFRS cohort also had a longer length of stay (2.3 ± 2.4 days vs. 7.0 ± 7.7 days, P < 0.001), higher non-routine discharge rate (19.9% vs. 39.9%, P < 0.001), and greater admission cost ($14,634 ± 5703 vs. $21,749 ± 15,234, P < 0.001). The Intermediate-High HFRS cohort had higher rates of 30- (7.6% vs. 11.0%, P < 0.001) and 90-day (6.8% vs. 8.3%, P < 0.001) readmissions. On a multivariate regression analysis, Intermediate-High HFRS compared to Low HFRS was an independent predictor of any AE (odds ratio, 16.6; 95% confidence interval, [12.9-21.5]; P < 0.001) and 30-day readmission (odds ratio, 1.4; 95% confidence interval, [1.2-1.7]; P < 0.001).

CONCLUSIONS

Our study suggests that frailty, as defined by HFRS, is associated with increased resource utilization in NPH patients undergoing VP shunt surgery. Furthermore, HFRS was an independent predictor of adverse events and 30-day hospital readmission.

Hospital Frailty Risk Score and healthcare resource utilization after surgery for metastatic spinal column tumors

OBJECTIVE

The Hospital Frailty Risk Score (HFRS) was developed utilizing ICD-10 diagnostic codes to identify frailty and predict adverse outcomes in large national databases. While other studies have examined frailty in spine oncology, the HFRS has not been assessed in this patient population. The aim of this study was to examine the association of HFRS-defined frailty with complication rates, length of stay (LOS), total cost of hospital admission, and discharge disposition in patients undergoing spine surgery for metastatic spinal column tumors.

METHODS

A retrospective cohort study was performed using the years 2016 to 2019 of the National Inpatient Sample (NIS) database. All adult patients (≥ 18 years old) undergoing surgical intervention for metastatic spinal column tumors were identified using the ICD-10-CM diagnostic codes and Procedural Coding System. Patients were categorized into the following three cohorts based on their HFRS: low frailty (HFRS < 5), intermediate frailty (HFRS 5-15), and high frailty (HFRS > 15). Patient demographics, comorbidities, treatment modality, perioperative complications, LOS, discharge disposition, and total cost of hospital admission were assessed. A multivariate logistic regression analysis was used to identify independent predictors of prolonged LOS, nonroutine discharge, and increased cost.

RESULTS

Of the 11,480 patients identified, 7085 (61.7%) were found to have low frailty, 4160 (36.2%) had intermediate frailty, and 235 (2.0%) had high frailty according to HFRS criteria. On average, age increased along with progressively worsening frailty scores (p ≤ 0.001). The proportion of patients in each cohort who experienced ≥ 1 postoperative complication significantly increased along with increasing frailty (low frailty: 29.2%; intermediate frailty: 53.8%; high frailty: 76.6%; p < 0.001). In addition, the mean LOS (low frailty: 7.9 ± 5.0 days; intermediate frailty: 14.4 ± 13.4 days; high frailty: 24.1 ± 18.6 days; p < 0.001), rate of nonroutine discharge (low frailty: 40.4%; intermediate frailty: 60.6%; high frailty: 70.2%; p < 0.001), and mean total cost of hospital admission (low frailty: $48,603 ± $29,979; intermediate frailty: $65,271 ± $43,110; high frailty: $96,116 ± $60,815; p < 0.001) each increased along with progressing frailty. On multivariate regression analysis, intermediate and high frailty were each found to be significant predictors of both prolonged LOS (intermediate: OR 3.75 [95% CI 2.96-4.75], p < 0.001; high: OR 7.33 [95% CI 3.47-15.51]; p < 0.001) and nonroutine discharge (intermediate: OR 2.05 [95% CI 1.68-2.51], p < 0.001; high: OR 5.06 [95% CI 1.93-13.30], p = 0.001).

CONCLUSIONS

This study is the first to use the HFRS to assess the impact of frailty on perioperative outcomes in patients with metastatic bony spinal tumors. Among patients with metastatic bony spinal tumors, frailty assessed using the HFRS was associated with longer hospitalizations, more nonroutine discharges, and higher total hospital costs.

Safety of oesophagogastroduodenoscopy in a nonagenarian population

BACKGROUND

invasive gastrointestinal (GI) procedures are increasingly performed on much older patients but data regarding oesophagogastroduodenoscopy (OGD) in this population are limited. We compared the indications, safety and benefits of OGD for nonagenarians compared to octogenarians.

METHODS

an observational retrospective review of patients who underwent OGD between 2013 and 2018 at a gastroenterology institute in one large hospital. Patients aged 90 and above 'nonagenarians' were compared to those aged 80-89 'octogenarians'.

RESULTS

472 patients (231 nonagenarians and 241 octogenarians), median age of 91 for nonagenarians (201 aged 90-94, 30 aged 95 and older) and 82 (174 aged 80-84, 67 aged 85-89) for octogenarians. GI bleeding was a more common and dyspepsia, a less common, indication for nonagenarians compared to octogenarians (55 and 7%, versus 43 and 18%). Significant findings and need for endoscopic treatments were both more commonly found in nonagenarians compared to octogenarians (25 and 24% versus 15 and 8%, respectively). General anaesthesia was more commonly given to nonagenarians (35 versus 10%). Immediate complications and 30-day mortality rate were similar between the groups: (2.6% of nonagenarians versus 1.6% of octogenarians). Of 30 patients aged 95 and older, 13% had late adverse events, compared to 1% of the overall cohort.

CONCLUSIONS

OGD appears safe in nonagenarians. Pathological findings and endoscopic interventions are more common. Decisions regarding OGD should not be based on age alone.
