Investigation of Geriatric Patients with Abdominal Pain Admitted to Emergency Department

Artificial intelligence driven malnutrition diagnostic model for patients with acute abdomen based on GLIM criteria: a cross-sectional research protocol

BACKGROUND

Patients with acute abdomen often experience reduced voluntary intake and a hypermetabolic process, leading to a high occurrence of malnutrition. The Global Leadership Initiative on Malnutrition (GLIM) criteria have rapidly developed into a principal methodological tool for nutritional diagnosis. Additionally, machine learning is emerging to establish artificial intelligent-enabled diagnostic models, but the accuracy and robustness need to be verified. We aimed to establish an intelligence-enabled malnutrition diagnosis model based on GLIM for patients with acute abdomen.

METHOD

This study is a single-centre, cross-sectional observational investigation into the prevalence of malnutrition in patients with acute abdomen using the GLIM criteria. Data collection occurs on the day of admission, at 3 and 7 days post-admission, including biochemical analysis, body composition indicators, disease severity scoring, nutritional risk screening, malnutrition diagnosis and nutritional support information. The occurrence rate of malnutrition in patients with acute abdomen is analysed with the GLIM criteria based on the Nutritional Risk Screening 2002 and the Mini Nutritional Assessment Short-Form to investigate the sensitivity and accuracy of the GLIM criteria. After data cleansing and preprocessing, a machine learning approach is employed to establish a predictive model for malnutrition diagnosis in patients with acute abdomen based on the GLIM criteria.

Factors associated with serious abdominal conditions in geriatric patients visiting the emergency department

BACKGROUND

Abdominal pain occurs in 20% of geriatric patients who visit the emergency department (ED). Geriatric patients usually have more severe conditions and a higher mortality rate. We aimed to determine the factors associated with serious abdominal conditions in geriatric patients who visit the ED with abdominal pain.

METHODS

This retrospective cohort study was conducted from January 1, 2017 to June 30, 2021. The inclusion criteria were patients aged ≥ 65 years and presented at the ED with acute abdominal pain. Significantly associated factors for serious abdominal conditions were examined using univariate and multivariate logistic regression analyses.

RESULTS

A total of 1221 patients were included in this study. Multivariate logistic regression analysis showed that the significant factors associated with serious abdominal conditions were male (adjusted odds ratio [AOR] 2.29, 95% CI:1.3-4.04; p = 0.004), anorexia (AOR 2.16, 95% CI:1.08-4.32; p = 0.03), NEWS 5-6 (AOR 2.96, 95% CI:1.35-6.49; p = 0.007), SBP 100-125 mmHg (AOR 1.5, 95% CI:0.75-2.99; p ≤ 0.001), guarding (AOR 6.92, 95% CI:3.39-14.12; p ≤ 0.001), WBC ≥ 14,000 cells/mm3 (AOR 2.08, 95% CI:1.06-4.09; p = 0.034), ED length of stay (EDLOS) 4-8 h (AOR 2.17, 95% CI:1.08-4.36; p = 0.03), and EDLOS ≥ 8 h (AOR 3.22, 95% CI:1.15-9; p = 0.025).

CONCLUSIONS

The statistically significant factors associated with serious abdominal conditions in geriatric patients were male, anorexia, NEWS 5-6, SBP 100-125 mmHg, guarding, WBC ≥ 14,000 cells/mm3, EDLOS 4-8 h, and EDLOS ≥ 8 h.

Pulmonary function and complication prevention: A randomized controlled trial on lung expansion modalities of older adults undergoing upper abdominal surgery

Postoperative pulmonary complications (PPCs) are a major catastrophic consequence of upper abdominal surgery, resulting in morbidity and mortality. Therefore, the study aims to assess the effect of lung expansion modalities (LEMs) on older adults' pulmonary function and the incidence of pulmonary complications. The study randomly allocated 80 older adults (40 cases and 40 controls). Pulmonary function testing revealed a significant improvement in the study group's forced expiratory volume in one second, sixth second, and oxygen saturation on the fifth postoperative day (POD) compared to the first day [55.23%, 38.41%, and 2.87%; P0.001]. The reported PPCs incidence of the intervention group was less than the control group (15% and 30% on the third POD; 15% and 37.5% on the fifth POD). In conclusion, LEMs provide practical enhancement for the postoperative care of older adults by reducing PPCs by restoring measured pulmonary volumes.

65 yaş üstü hastalarda puanlama sistemlerinin şiddetli akut pankreatiti ve mortaliteyi erken öngörme açısından değerlendirilmesi

Purpose: The aim of this study is to investigate the power of disease severity scores to predict the development of Severe Acute Pancreatitis (SAP) and mortality in the early period over 65 years old diagnosed with acute pancreatitis in the emergency department. Materials and Methods: We calculated RANSON (on admission) and Computed Tomography Severity Index (CTSI) in addition to Bedside Index for Severity in Acute Pancreatitis (BISAP) score on admission to the emergency department. Results: One hundred and sixty patients (46.9% over 80 years of age) were included in the study. We observed statistically higher length of hospitalization, longer duration of stay in the intensive care unit, SAP and higher mortality in patients over 80 years of age. When we examined the ROC curve, we determined that the AUC values of the BISAP score were highest in both SAP and mortality estimation (AUC: 0.911, 95% CI 0.861-0.962; AUC: 0.918, 95% CI 0.864-0.9722, respectively). Binary logistic analysis indicated a 4.7-fold increased risk for SAP and a 12.3-fold increased mortality for each unit increase in BISAP score value. Conclusion: BISAP may be a good predictor for SAP and mortality estimation on admission to the emergency department in patients over 65 years of age with acute pancreatitis.

Indications for Emergency Abdominal Surgeries in Older Patients: 7-Year Experience of a Single Centre

The majority of patients undergoing emergency laparotomy are older adults that carry the highest mortality. More research into the development of targeted interventions is required. Therefore, the aim of the study was to analyse the indications for emergency abdominal surgery in patients aged ≥ 65 admitted to the Department of General Surgery. The study included consecutive patients aged ≥ 65 who underwent emergency abdominal surgery within 48 h after admission at one institution. In 2010–2017, 986 patients were enrolled in the study (female 57%, male 43%). Patients were divided into three age groups, 65–70, 71–84 and ≥ 85, with 255 patients (25.9%), 562 patients (57.0%) and 169 patients (17.1%) in each group, respectively. In the first and second age groups, the most common indications for surgery were acute cholecystitis, non-malignant ileus, colorectal cancer complications and acute appendicitis. In the oldest patients, the most common indications were complications of colorectal cancer, acute cholecystitis, non-malignant ileus and complications of diverticulosis. In the women, the biggest differences in indications between age groups were colorectal cancer (p = 0.025) and peptic ulcer disease complications (p = 0.005); in the men, the biggest difference was seen for complicated diverticulitis (p = 0.001). The most frequent comorbidities were heart diseases (81.0%), followed by endocrine (33.6%) and vascular diseases (22.7%). The three most common indications for emergency surgery in older patients at our institution were acute cholecystitis, colorectal cancer complications and non-malignant bowel obstruction, affecting 59.5% of this group of patients. Elective surgery and endoscopic screening have the potential to prevent major part of these acute diseases. However, further prospective research is necessary on this field, particularly among frail, older patients.

Acute abdominal disease with nonspecific symptoms in the elderly: A case series

Acute stomach disease in elderly patients often lacks characteristic clinical manifestations. Presentations may differ from those in younger patients and are often complicated by concomitant diseases, delayed presentation, and misdiagnosis. Incorrect diagnosis and treatment can lead to medical-related death claims. We investigated eight cases of elderly fatality due to acute abdominal diseases in forensic autopsy cases. Although most fatalities were unwitnessed, possibly due to the characteristics of elderly individuals, recent social backgrounds, and involvement with health care, some cases of possible misdiagnosis suggested that physicians should carefully consider atypical clinical manifestations and the characteristics of elderly individuals when the managing abdominal symptoms, particularly in primary health care. Our investigation of these forensic autopsy cases indicated the particular importance of peritoneal adhesions as an unexpected cause of acute abdomen in the elderly due to strangulation ileus, even among those with no history of abdominal surgery or trauma. Diagnosis of acute stomach symptoms can be difficult in elderly patients. Pathophysiological examination and autopsy analyses can thus contribute to early-stage diagnosis and prevention of acute stomach symptoms in elderly patient populations.

Acute abdominal pain in older adults: a clinical and diagnostic challenge

INTRODUCTION

Abdominal pain (AP) is one of the most frequent clinical condition observed in elderly patients. The differential diagnosis is wide and definitive diagnosis is often difficult due to delayed symptoms, altered laboratory parameters, pre-existing medical disorders, abuse of drugs and in absence of an accurate medical history.

EVIDENCE ACQUISITION

A systematic literature review was carried out through PubMed database for studies published in the last ten years. The following search string was used: {("geriatric"[Title] OR "older"[Title] OR "aged"[Title] OR "elderly"[Title]) AND ((("abdomen"[Title] AND "acute"[Title]) OR "acute abdomen"[Title] OR ("acute"[Title] AND "abdomen"[Title])) OR ("abdominal"[Title] AND "pain"[title]) OR "abdominal pain"[Title])}. Full articles and abstracts were included. Case reports, commentaries, editorials and letters were excluded from the analysis.

EVIDENCE SYNTHESIS

As the age of people presenting AP advances, both rates of surgical procedures and mortality rate increase.

CONCLUSIONS

A systematic approach based on the organization of differential diagnoses into categories, may provide a helpful framework by the combined use of history-taking, physical examination, and results of diagnostic studies. In elderly patients admitted to the emergency department, a crucial role is played by a prompt use of radiological investigations in order to discriminate between older subjects admitted to the emergency department with abdominal pain and pathological cases requiring immediate surgical treatment.
