[PMID: 38172691 PMCID: PMC10762826 DOI: 10.1186/s12877-023-04621-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Accepted: 12/18/2023] [Indexed: 01/05/2024] Open
Abstract
BACKGROUND Older adults have complex medical needs that causes increased use of resources at the emergency department (ED). The prevalence of non-specific complaint (NSC) as a chief-complaint in the ED is common among older adults and is not prioritized even though possibly having worse clinical outcome. The objective was to study hospital admission and mortality for older adults visiting the ED with NSC compared to specific complaints such as dyspnea, chest pain and abdominal pain. METHODS A retrospective observational study of older adults visiting the ED with NSC and specific complaints; dyspnea, chest pain and abdominal pain was performed. Chief-complaint were collected from electronic medical records. Fatigue, confusion, non-specific complaints, generalized weakness and risk of falling were defined as non-specific complaint (NSC) when registered as chief-complaint at the ED. Admission rate and 30-days mortality were the primary outcomes. RESULTS A total of 4927 patients were included in the study based on chief-complaint; patients with chest pain 1599 (32%), dyspnea 1343 (27%), abdominal pain 1460 (30%) and NSC 525 (11%). Patients with dyspnea and NSC had the highest hospital admission rate 79% vs 70% compared to patients with chest pain (63%) and abdominal pain (61%) (p = < 0.001). Patients with NSC had a mean LOS 4.7 h at the ED which was significantly higher compared to chest pain, dyspnea and abdominal pain. Mean bed-days for the whole population was 4.2 days compared to patients with NSC who had a mean LOS of 5.6 days. NSC and dyspnea were both associated with the highest 30-day mortality. CONCLUSION Older patients who present with NSC at the ED are associated with a high risk for admission and 30-days mortality. In addition, patients with NSC have a longer LOS at the ED, a high admission rate and the highest number of bed-days once admitted. This study indicates that ED staff should be more vigilant when an elderly patient presents with NSC at the ED. Further studies and guidelines are needed to improve the management of these individuals.

Abstract
INTRODUCTION The predictive power of chief complaints reported at presentation to the emergency department (ED) is well known. However, there is a lack of research on the coherence of patient versus physician reported chief complaints. The aim of this study was to determine the rate of disagreement between patients and physicians regarding chief complaint and its significance for the prediction of the outcomes number of resources used during ED work-up, hospitalisation, ICU admission, in-hospital mortality and hospital length of stay. METHODS In this secondary analysis of a study conducted over a time course of 9 weeks, consecutive emergency patients and their physicians were independently asked to report the chief complaint upon presentation. The two reports were assessed for pair-wise agreement. RESULTS Of 6722 emergency patients (mean age 53.3, 46.8% female), the median number of symptoms reported by patients was two and one reported by physicians. The rate of disagreement on chief complaints was 32.6%. Disagreement was associated with a higher number of resources (β = 0.24; CI, 0.18, 0.31, P <.001) and hospitalisation (OR = 1.31; CI, 1.16, 1.48, P <.001), using multivariable analyses. Patient factors associated with disagreement were age (OR = 1.01; CI, 1.01, 1.01, P <.001), number of patient reported symptoms (OR = 1.27; CI, 1.23, 1.32, P <.001) and male gender (OR = 1.12; 1.01, 1.25, P =.0285). CONCLUSION Disagreement on chief complaint between patient and physician may be an early marker for a complex work-up, requiring more resources and hospitalisations. The relevance of this finding is the newly identified signal of chief complaint replacement. It is easy to identify and should generate attention, as it affects a certain phenotype (older male patients with higher numbers of complaints).

Abstract
BACKGROUND Nonspecific complaint (NSC) is a common presenting complaint in the emergency setting, especially in the elderly population. Individual studies have shown that it is associated with significant morbidity and mortality. This prognostic systematic review draws a synthesis of reported outcomes for patients presenting with NSC and compares them with outcomes for patients presenting with a specific complaint. METHODS We conducted a literature search for publications, abstracts and conference presentations from Ovid, Scopus and Web of Science for the past 20 years. Studies were included which treated adult patients presenting to the Emergency Medical Services or Emergency Department with NSC. 2599 studies were screened for eligibility and quality was assessed using the SIGN assessment for bias tool. We excluded any low-quality studies, resulting in nine studies for quantitative analysis. We analysed the included studies for in-hospital mortality, triage category, emergency department length of stay, admission rate, hospital length of stay, intensive care admissions and re-visitation rate and compared outcomes to patients presenting with specific complaints (SC), where data were available. We grouped discharge diagnoses by ICD-10 category. RESULTS We found that patients presenting with NSC were mostly older adults. Mortality for patients with NSC was significantly increased compared to patients presenting with SC [OR 2.50 (95% CI 1.40-4.47)]. They were triaged as urgent less often than SC patients [OR 2.12 (95% CI 1.08-4.16)]. Emergency department length of stay was increased in two out of three studies. Hospital length of stay was increased by 1-3 days. Admission rates were high in most studies, 55 to 84%, and increased in comparison to patients with SC [OR 3.86 (95% CI 1.76-8.47)]. These patients seemed to require more resources than patients with SC. The number for intensive care admissions did not seem to be increased. Data were insufficient to make conclusions regarding re-visitation rates. Discharge diagnoses were spread throughout the ICD-10 main chapters, infections being the most prevalent. CONCLUSIONS Patients with NSC have a high risk of mortality and their care in the Emergency Department requires more time and resources than for patients with SC. We suggest that NSC should be considered a major emergency presentation.

Abstract
OBJECTIVE We conducted this study to investigate whether ESI combined with qSOFA score (ESI+qSOFA) predicts hospital outcome better than ESI alone in the emergency department (ED). METHODS This was a retrospective study for patients aged over 15years who visited an ED of a tertiary referral hospital from January 1st, 2015 to December 31st, 2015. We calculated and compared predictive performances of ESI alone and ESI+qSOFA for prespecified outcomes. The primary outcome was hospital mortality, and the secondary outcome was composite outcome of in-hospital mortality and ICU admission. We calculated in-hospital mortality rates by positive qSOFA in each subgroup divided according to ESI levels (1, 2, 3, 4+5). RESULTS 43,748 patients were enrolled. The area under receiver-operating characteristics curves were higher in ESI+qSOFA than in ESI alone for both mortality and composite outcome (0.786 vs. 0.777, P<.001 for mortality; 0.778 vs. 0.774, P<.001 for composite outcome). In each subgroup divided by ESI levels, patients with positive qSOFA had significantly higher in-hospital mortality rate compared to those with negative qSOFA (20.4% vs. 14.7%, P=.117 in ESI level 1 subgroup; 11.3% vs. 2.7%, P=.001 in ESI level 2 subgroup; 2.3% vs. 0.4%, P<.001 in ESI level 3 subgroup; 0.0% vs. 0.0% in ESI level 4 or 5 subgroup). CONCLUSION The prognostic performance of ESI+qSOFA for in-hospital mortality was significantly higher than that of ESI alone. Within each subgroup, patients with positive qSOFA had higher in-hospital mortality compared to those with negative qSOFA.

Abstract
Patients with nonspecific complaints (NSC) presenting to the emergency department (ED) are at risk of life-threatening conditions. New stress biomarkers such as the midregional portion of adrenomedullin (MR-proADM) promise to support decision-making. This study tested the following hypotheses: biomarker-assisted disposition of patients with NSC will not increase mortality. Second, discharge from the ED will increase if clinical risk assessment is combined with low MR-proADM levels. Third, inappropriate disposition to a lower level of care will decrease, if clinical assessment is combined with high MR-proADM levels, and fourth that this algorithm is feasible in the ED setting. Prospective, multicenter, randomized, controlled interventional feasibility study with a 30-day follow-up, including patients with NSC. Patients were randomly assigned to either the standard group (decision-making solely based on clinical assessment) or the Novum group (biomarker-assisted). Regarding disposition, patients were assigned to 1 of 3 risk classes: high-risk (admission to hospital), intermediate risk (community geriatric hospital), and low-risk patients (discharge). In the Novum group, in addition to clinical risk assessment, the information of the MR-proADM level was used. Unless there were overruling criteria, patients were transferred or discharged according to the risk assessment. Primary endpoint was 30-day mortality. Secondary endpoints were comparisons of patient disposition and related mortality rates, ED, and hospital length of stay and readmission. The final study cohort consisted of 398 patients (210 in the Standard group and 188 in the Novum group). Overruling, that is, disposition not according to the result of the proposed algorithm occurred in 51 cases. Baseline characteristics between Standard and Novum groups were similar. The mortality rate in the Novum group was 4.3%, as compared to the Standard group mortality of 6.2%, which was not significantly different (intention-to treat analysis). This was confirmed by the perprotocol analysis as well as by sensitivity analysis. For the secondary endpoints, no significant differences were detected. Biomarker-assisted disposition is safe in patients with NSC. Discharge rates did not increase. Feasibility could only partly be shown due to an unexpectedly high overruling rate. Inappropriate disposition to lower levels of care did not change. ClinicalTrials. gov Identifier: NCT00920491.

Abstract
The prevalence of diagnoses, morbidity, and mortality of patients with nonspecific complaints (NSC) presenting to the emergency department (ED) is unknown.To determine the prevalence of diagnoses, acute morbidity, and mortality of patients with NSC.Prospective observational study with a 30-day follow-up. Patients presenting to 2 EDs were enrolled by a study team and diagnosed according to the World Health Organization ICD-10 System.Of 217,699 presentations to the ED from May 2007 through to February 2011, a total of 1300 patients were enrolled. After exclusion of 90 patients who fulfilled exclusion criteria, 1210 patients were analyzed. No patient was lost to follow-up. In patients with NSC, the underlying diseases were spread throughout 18 chapters of the ICD-10. A total of 58.7% of the patients were diagnosed with acute morbidity. Thirty-day mortality was 6.4% overall. Patients with acute morbidity and suffering from heart failure and pneumonia had mortalities >15%; patients lacking acute morbidity, but suffering from functional impairment or depression/anxiety had mortalities of 0%. Although the history did not allow any prediction, age and sex were predictive of morbidity and mortality.The differential diagnoses in patients presenting with NSC is broad. Acute morbidity and mortality were high in the presented cohort, the predictors of morbidity and mortality being age and sex rather than the nature of the complaints. Urgently needed management strategies could be based on these results.ClinicalTrials.gov (#NCT00920491).

Abstract
OBJECTIVES To the authors' knowledge, no prospectively validated, biomarker-based risk stratification tools exist for elderly patients presenting to the emergency department (ED) with nonspecific complaints (NSCs), such as generalized weakness, despite the fact that an acute serious disease often underlies nonspecific disease presentation. The primary purpose for this study was to validate the retrospectively derived model for outcome prediction using copeptin and peroxiredoxin 4 (Prx4), in a different group of patients, in a prospective fashion, in a multicenter setting. The secondary goals were to evaluate the potential contribution of the midregional portion of the precursor of adrenomedullin (MR-proADM) for outcome prediction and to investigate whether disposition decisions show promise for potential improvement by using biomarker levels in addition to a clinical assessment. METHODS The Basel Nonspecific Complaints (BANC) study is a delayed-type cross-sectional diagnostic study, carried out in three EDs in Switzerland, with a prospective 30-day follow-up. Patients presenting to the ED with NSCs, as defined previously, were included if their vital signs were within predefined limits. Measurement of biomarkers was performed in serum samples with sandwich immunoluminometric assays. To examine the disposition process, the final disposition was compared with a combination of the first clinical disposition decision and the risk assessment, which included the biomarker MR-proADM in a retrospective simulation. Patients were divided into three groups according to MR-proADM concentration, defining three risk classes with three disposition possibilities (admission to tertiary care, transfer to geriatric hospital, discharge). RESULTS Thirty-three 30-day nonsurvivors were observed from among 504 study patients with NSCs. Biomarker levels were significantly greater in nonsurvivors than survivors (p < 0.0001 for all three biomarkers). Univariate Cox models reveal a C-index of 0.732 for MR-proADM, 0.719 for Prx4, and 0.723 for copeptin. The incremental added value for chi-square obtained via multivariate modeling showed that models inclusive of MR-proADM, copeptin, or Prx4 are superior to and independent of models limited to sex and age. The incrementally added chi-square for MR-proADM, beyond the chi-square of a base model consisting of age and sex, was 29.79 (p < 0.00001). In a multimarker approach, only Prx4 provided additional information to MR-proADM alone (C-index = 0.77). Applying an algorithm combining physicians' first clinical assessment plus biomarker information to derive a modified risk assessment, reassignment would lead to a potential decrease of 48 admissions to acute care, seven additional transfers to geriatric care, and 41 additional discharges (negative likelihood ratio [-LR] = 0.13). Analysis of 30-day mortality reveals that our algorithm is not inferior in terms of safety. CONCLUSIONS In this study the authors confirm that these new stress biomarkers permit reliable prognostication of adverse outcomes in a heterogeneous group of patients with NSCs. A simulation showed that this prognostic information could be useful to enhance the appropriateness of disposition decisions of ED patients with NSC. The use of biomarkers for risk stratification in this patient group should be evaluated with prospective intervention studies.

Abstract
Background Since drug-related emergency department (ED) visits are common among older adults, the objectives of our study were to identify the frequency of drug-related problems (DRPs) among patients presenting to the ED with non-specific complaints (NSC), such as generalized weakness and to evaluate responsible drug classes. Methods Delayed type cross-sectional diagnostic study with a prospective 30 day follow-up in the ED of the University Hospital Basel, Switzerland. From May 2007 until April 2009, all non-trauma patients presenting to the ED with an Emergency Severity Index (ESI) of 2 or 3 were screened and included, if they presented with non-specific complaints. After having obtained complete 30-day follow-up, two outcome assessors reviewed all available information, judged whether the initial presentation was a DRP and compared their judgment with the initial ED diagnosis. Acute morbidity (“serious condition”) was allocated to individual cases according to predefined criteria. Results The study population consisted of 633 patients with NSC. Median age was 81 years (IQR 72/87), and the mean Charlson comorbidity index was 2.5 (IQR 1/4). DRPs were identified in 77 of the 633 cases (12.2%). At the initial assessment, only 40% of the DRPs were correctly identified. 64 of the 77 identified DRPs (83%) fulfilled the criteria “serious condition”. Polypharmacy and certain drug classes (thiazides, antidepressants, benzodiazepines, anticonvulsants) were associated with DRPs. Conclusion Elderly patients with non-specific complaints need to be screened systematically for drug-related problems. Trial Registration ClinicalTrials.gov: NCT00920491

Abstract
OBJECTIVE To investigate diagnostic accuracy in patient histories involving nonspecific complaints and the extent to which characteristics of physicians and structural properties of patient histories are associated with accuracy. METHODS Six histories of patients presenting to the emergency department (ED) with nonspecific complaints were provided to 112 physicians: 36 ED physicians, 50 internists, and 26 family practitioners. Physicians listed the 3 most likely diagnoses for each history and indicated which cue(s) they considered crucial. Four weeks later, a subset of 20 physicians diagnosed the same 6 histories again. For each history, experts had previously determined the correct diagnoses and the diagnostic cues. RESULTS Accuracy ranged from 14% to 64% correct diagnoses (correct diagnosis listed as the most likely) and from 29% to 87% correct differential diagnoses (correct diagnosis listed in the differential). Acute care physicians (ED physicians and internists) included the correct diagnosis in the differential in, on average, 3.4 histories, relative to 2.6 for the family practitioners (P = 0.001, d = .75). Diagnostic performance was fairly reliable (r = .61, P < 0.001). Clinical experience was negatively correlated with diagnostic accuracy (r = -.25, P = 0.008). Two structural properties of patient histories-cue consensus and cue substitutability-were significantly associated with diagnostic accuracy, whereas case difficulty was not. Finally, prevalence of diagnosis also proved significantly correlated with accuracy. CONCLUSIONS Average diagnostic accuracy in cases with nonspecific complaints far exceeds chance performance, and accuracy varies with medical specialty. Analyzing cue properties in patient histories can help shed light on determinants of diagnostic performance and thus suggest ways to enhance physicians' ability to accurately diagnose cases with nonspecific complaints.

Abstract
OBJECTIVES Patients presenting to emergency departments (ED) with nonspecific complaints (NSCs) such as "not feeling well,""feeling weak,""being tired,""general deterioration," or other similar chief complaints that do not have a readily identifiable probable etiology are a common patient group at risk for adverse outcomes. Certain biomarkers, which have not yet been tested for prognostic value when applied to ED patients with NSCs, have emerged as useful tools for predicting prognosis in patients with a variety of diseases. This study tested the hypothesis that two of these novel markers, copeptin (a C-terminal portion of provasopressin) and/or peroxiredoxin-4 (Prx4), an enzyme that degrades hydrogen peroxide, singly or together are helpful in predicting death in the near term among patients presenting to the ED with NSCs. METHODS The Basel Non-specific Complaints (BANC) study is a delayed type cross-sectional diagnostic study with a prospective 30-day follow-up. ED patients with NSCs were consecutively enrolled. Patients with vital parameters out of the normal range were excluded. The primary endpoint of this study was the predictive value of copeptin and Prx4 for 30-day mortality in patients with NSCs. Measurement of both copeptin and Prx4 was performed in serum samples with sandwich immunoluminometric assays. RESULTS On follow-up at 30 days after ED presentation, 28 of 438 patients with NSC had died. Copeptin and Prx4 concentrations were significantly higher in nonsurvivors than in survivors (Kruskal-Wallis test, p = 0.0001 and p < 0.0001, respectively). In univariate models, Prx4 (likelihood ratio [LR] χ(2) = 22.24, p < 0.00001, concordance index [C-index] = 0.749) and copeptin (LR χ(2) = 16.98, p = 0.00004, C-index = 0.724) were both predictive of 30-day mortality, and elevated levels were associated with an increased mortality. The bivariable model, which included both Prx4 and copeptin (LR χ(2) = 28.22, p < 0.00001, C-index = 0.783), allows a significantly better prediction than the univariate Prx4 (p = 0.00025) and copeptin models (p = 0.00099), respectively. Both biomarkers provided independent and additional information to clinical risk scores (Katz Activities of Daily Living [ADL] and Charlson Comorbidity Index [CCI], all p < 0.0005). CONCLUSIONS Copeptin and Prx4 are new prognostic markers in patients presenting to the ED with NSCs. Copeptin and Prx4 might be valuable tools for risk stratification and decision-making in this patient group.

Abstract
OBJECTIVES Patient management in emergency departments (EDs) is often based on management protocols developed for specific complaints like dyspnea, chest pain, or syncope. To the best of our knowledge, to date no protocols exist for patients with nonspecific complaints (NSCs) such as "weakness,""dizziness," or "feeling unwell." The objectives of this study were to provide a framework for research and a description of patients with NSCs presenting to EDs. METHODS Nonspecific complaints were defined as the entity of complaints not part of the set of specific complaints for which evidence-based management protocols for emergency physicians (EPs) exist. "Serious conditions" were defined as potentially life-threatening or those requiring early intervention to prevent health status deterioration. During a 6-month period, all adult nontrauma patients with an Emergency Severity Index (ESI) of 2 or 3 were prospectively enrolled, and serious conditions were identified within a 30-day period. RESULTS The authors screened 18,261 patients for inclusion. A total of 218 of 1,611 (13.5%) nontrauma ESI 2 and 3 patients presented with NSCs. Median age was 82 years (interquartile range [IQR]=72 to 87), and 24 of 218 (11%) were nursing home inhabitants. A median of 4 (IQR=3 to 5) comorbidities were recorded, most often chronic hypertension, coronary artery disease, and dementia. During the 30-day follow-up period a serious condition was diagnosed in 128 of 218 patients (59%). The 30-day mortality rate was 6%. CONCLUSIONS Patients with NSC presenting to the ED are at high risk of suffering from serious conditions. Sensitive risk stratification tools are needed to identify patients with potentially adverse health outcomes.
