Hospital Emergency Departments—Utilization and Resource Deployment in the Hospital as a Function of the Type of Referral

Capabilities of ChatGPT-3.5 as a Urological Triage System

Background and objective

Patients struggle to classify symptoms, which hinders timely medical presentation. With 35-75% of patients seeking information online before consulting a health care professional, generative language-based artificial intelligence (AI), exemplified by ChatGPT-3.5 (GPT-3.5) from OpenAI, has emerged as an important source. The aim of our study was to evaluate the role of GPT-3.5 in triaging acute urological conditions to address a gap in current research.

Methods

We assessed GPT-3.5 performance in providing urological differential diagnoses (DD) and recommending a course of action (CoA). Six acute urological pathologies were identified for evaluation. Lay descriptions, sourced from patient forums, formed the basis for 472 queries that were independently entered by nine urologists. We evaluated the output in terms of compliance with the European Association of Urology (EAU) guidelines, the quality of the patient information using the validated DISCERN questionnaire, and a linguistic analysis.

Key findings and limitations

The median GPT-3.5 ratings were 4/5 for DD and CoA, and 3/5 for overall information quality. English outputs received higher median ratings than German outputs for DD (4.27 vs 3.95; p < 0.001) and CoA (4.25 vs 4.05; p < 0.005). There was no difference in performance between urgent and non-urgent cases. Analysis of the information quality revealed notable underperformance for source indication, risk assessment, and influence on quality of life.

Conclusion and clinical implications

Our results highlights the potential of GPT-3.5 as a triage system for offering individualized, empathetic advice mostly aligned with the EAU guidelines, outscoring other online information. Relevant shortcomings in terms of information quality, especially for risk assessment, need to be addressed to enhance the reliability. Broader transparency and quality improvements are needed before integration into, primarily English-speaking, patient care.

Patient summary

We looked at the performance of ChatGPT-3.5 for patients seeking urology advice. We entered more than 400 German and English inputs and assessed the possible diagnoses suggested by this artificial intelligence tool. ChatGPT-3.5 scored well in providing a complete list of possible diagnoses and recommending a course of action mostly in line with current guidelines. The quality of the information was good overall, but missing and unclear sources for the information can be a problem.

Evaluation of an Automated Decision Aid for the Further Referral of Emergency Room Patients—A Prospective Cohort Study

BACKGROUND

Instruments for the initial evaluation of emergency room patients as an aid to their onward referral to ambulatory care structures are a matter of current interest. In this study, we assess the safety of the software application SmED-Kontakt+ for this purpose. SmED is an abbreviation for Strukuturierte Medizinische Ersteinschätzung Deutschland, "structured initial medical evaluation in Germany."

METHODS

In this prospective cohort study, we compared the recommendations of SmED-Kontakt+ concerning the time and place of further care with those of the treating physicians. The subjects were adult patients who were able to walk and had presented themselves to the emergency room. Whenever SmED-Kontakt+ assessed the situation less critically than the physicians, and in 5% of the remaining cases, the potential endangerment of patient safety was assessed by an expert panel (expected value <1%).

RESULTS

In a total of 1840 cases, SmED-Kontakt+ agreed with the physicians' assessment in 353 (19%). The assessment of SmED-Kontakt+ was more critical in 1221 cases (66%) and less critical in 266 (15%; potential undertriage). There was potential endangerment in 49 cases (2.7%; 95% confidence interval [2.0; 3.5]). Potential endangerment was less common among patients in the more urgent recommendation categories [0.1; 2.6] and more common in the categories of a recommended outpatient physician visit or telephone consultation within or beyond 24 hours [2.4; 17.2].

CONCLUSION

SmED-Kontakt+ generally assessed these patients' needs for further care as more urgent than the treating physicians did. Nevertheless, the percentage of potentially endangered patients was higher than expected. We conclude that further care should be provided in timely fashion with an obligatory appointment. The sites of further ambulatory care should be immediately accessible and properly equipped. Patients should not be referred for further care at later times on the basis of an SmED-Kontakt+ assessment.

[Multimorbidity as a predictor for inpatient admission in clinical emergency and acute medicine : Single-center cluster analysis]

BACKGROUND

Parallel to demographic trends, an increase of multimorbid patients in emergency and acute medicine is prominent. To define easily applicable criteria for the necessity of inpatient admission, a hierarchical cluster analysis was performed.

METHODS

In a retrospective, single-center study data of n = 35,249 emergency cases (01/2016-05/2018) were statistically analyzed. Multimorbidity (MM) was defined by at least five ICD-10-GM diagnoses resulting from treatment. A hierarchical cluster analysis was performed for those diagnoses initially summarized into 112 diagnosis subclusters to determine specific clusters of in- and outpatient cases.

RESULTS

Hospital admission was determined in 81.2% of all ED patients (n = 28,633); 54.7% of inpatients (n = 15,652) and 0.97% of outpatient cases (n = 64) met the criteria for multimorbidity and the age difference between them was highly significant (68.7/60.8 years; p < 0.001). Using a hierarchical cluster analysis, 13 clusters with different diagnoses were identified for inpatient multimorbid patients (MP) and 7 clusters with primarily hematological malignancies for outpatient MP. The length of stay in the ED of inpatient MP was more than twice as long (max. 8.3 h) as for outpatient MP (max. 3.2 h.).

CONCLUSIONS

The combination of diagnoses typical for MM were characterized as clusters in this study. In contrast to single or combined single diagnoses, the statistically determined characterization of clusters allows for a significantly more accurate prediction of ED patients' disposition as well as for economic process allocation.

[Pediatric emergency patients in the emergency departments of a German metropolitan region : A retrospective cross-sectional study over a one-year period]

BACKGROUND

To date, no detailed analysis of pediatric emergencies treated in emergency departments (ED) exists. However, in the context of capacity planning and upcoming emergency care reform in Germany, these data are urgently needed.

METHODS

Retrospective, multicenter cross-sectional study for the period 01 July 2013 to 01 June 2014 of pediatric cases in emergency departments in Munich.

RESULTS

A total of 103,830 cases were analyzed (age: 6.9 ± 5.4 years, boys/girls 55%/45%). A total of 85.9% of cases were treated as outpatients, 12.4% (9.6 per 100,000 children) were admitted to normal and 1.7% (1.0 per 100,000 children) to intensive care. However, the real bed requirements exceeded these guideline numbers, with an absolute requirement of 4.9 ICU beds and 35.1 normal ward beds per day. Load peaks were seen on Wednesday and Friday afternoons and on weekends. Every 8th patient who presented to an ED as a self-referral was treated as an inpatient.

CONCLUSION

Capacity planning for inpatient emergency care of pediatric patients requires planning for more beds than can be expected on a population basis. The availability of panel physician care influences patient volume in the EDs. Initial medical assessment tools for treatment need and urgency are needed to distribute patients. The pediatric emergency centers planned as part of the current reform of emergency care must be adequately staffed and financed in order to be able to handle-in close cooperation with statutory health insurance-accredited medical care-the expected demand for care.

Insights from end-of-career general practitioners on changing working conditions and generational differences: considerations for future strategies

The landscape of general practice has experienced notable transformations in recent decades, profoundly influencing the working conditions of general practitioners (GPs). This study aimed to examine the most salient changes affecting GPs' daily practices. Through semi-structured qualitative interviews with 15 end-of-career GPs, the study explored how these changes affected work organization, equipment, working hours, work-life balance, job satisfaction, training, patient relationships, and reputation. The interviews revealed that these changes were perceived as barriers, opportunities, or a complex interplay of both for general practice. While the interviewed GPs valued technological advancements and reported positive developments in working conditions, challenges included a gradual reduction in the range of tasks, growing administrative burdens, and less practical training for young physicians. Other changes, such as new doctor-patient dynamics, the transition from single to group practice, and differing professional expectations of the younger generation, were seen as both challenging and strengthening for general practice. By combining these factors and trade-offs observed by end-of-career GPs in our study over the past few decades with general societal changes, we provide ideas for the design of future framework conditions in general practice that might enhance the attractiveness of the profession. These insights offer key considerations that can guide future strategies for general practice and medical education.

Institutional Surgical Setting and Volume Effects of Certified Arthroplasty Centers in Germany: Evaluation of the Quality of Care in a 5-Year Comparison

To improve arthroplasty care quality, the EndoCert initiative focuses on structural, processual, and surgeon-related quality assurance. The aim of this study was to assess the impact of a surgeon's case load in certified centers on quality of care, distinguished by different types of surgeons. Data from the annual reports of EndoCert certified centers for the years 2017 to 2021 were analyzed. The study revealed reduced numbers of cases, while the number of surgeons remained constant. Since 2020, the decrease in the average case load per surgeons has become more pronounced. There were also differences between senior (sECrs) and EndoCert-registered surgeons (ECrs). Before the 2020 pandemic, over half of surgeons exceeded minimum annual case requirements, while, afterwards, this number declined, especially for the ECrs. Affiliated surgeons, who are also sECrs or ECrs, performed predominantly lower numbers of arthroplasties. However, a higher percentage of affiliated surgeons in a center correlated with faster surgeries and lower mortality rates. High numbers of arthroplasties per center or surgeon were not necessarily associated with better quality indicators, especially in the knee. While the comprehensive quality standards may offset volume effects, EndoCert should reconsider minimum volume regulations based on surgeon, but also on each joint.

Recruiting patients for falls prevention in the emergency department - worth the challenge

BACKGROUND

Severe falls escalate the risk of future falls and functional decline as indicated by recent global guidelines. To establish effective falls prevention, individuals at highest risk must be thoroughly studied and, therefore, successfully recruited.

OBJECTIVE

Recruiting from an emergency department (ED) may mitigate common selection biases, such as overrepresentation of individuals with a higher social status and healthier lifestyle. However, this approach presents unique challenges due to ED-specific conditions. Hence, we present the successes and challenges of an ED-based recruitment for an observational study.

METHODS

The SeFallED study targets older adults aged ≥60 years, who present to either of two hospitals in Oldenburg after a fall without subsequent admission. A study nurse addressed individuals in the EDs. Subsequently, potential participants were contacted by phone to arrange a home visit for obtaining written consent. Data of participants were compared with total admissions during the recruitment period to determine recruitment rate and compare patients' characteristics.

RESULTS

Over 1.500 individuals met the inclusion criteria. Of these, 288 participants were successfully recruited. Most patients presented to the ED outside of the study team's working hours, and some opted not to participate (main reason: too unwell (40%)). Compared to working hours, a participant was recruited every 14 h. Comparing characteristics, a trend towards better health and younger age was observed.

CONCLUSION

ED-based recruitment offers the opportunity to include more diverse individuals in falls prevention. To achieve adequate sample sizes, flexibility in working days and hours of the research team are obligatory.

Do patients referred to emergency departments after being assessed in primary care differ from other ED patients? Retrospective analysis of a random sample from two German metropolitan EDs

BACKGROUND

To assess differences between patients referred to emergency departments by a primary care physician (PCP) and those presenting directly and the impact of referral on the likelihood of admission.

DESIGN OF STUDY

Retrospective cohort study.

SETTING

EDs of two nonacademic general hospitals in a German metropolitan region.

PARTICIPANTS

Random sample of 1500 patients out of 80,845 presentations during the year 2019.

RESULTS

Age was 55.8 ± 22.9 years, and 51.4% was female. A total of 34.7% presented by emergency medical services (EMS), and 47.7% were walk-ins. One-hundred seventy-four (11.9%) patients were referred by PCPs. Referrals were older (62.4 ± 20.1 vs 55.0 ± 23.1 years, p < .001) and had a higher Charlson Comorbidity Index (CCI) (3 (1-5) vs 2 (0-4); p < .001). Referrals received more ultrasound examinations independently from their admission status (27.6% vs 15.7%; p < .001) and more CT and laboratory investigations. There were no differences in sex, Manchester Triage System (MTS) category, or pain-scale values. Referrals presented by EMS less often (9.2% vs 38.5%; p < .001). Admission rates were 62.6% in referrals and 37.1% in non-referrals (p < .001). Referral (OR 3.976 95% CI: 2.595-6.091), parenteral medication in ED (OR 2.674 (1.976-3.619)), higher MTS category (1.725 (1.421-2.093)), transport by EMS (1.623 (1.212-2.172)), abnormal vital parameters (1.367 (0.953-1.960)), higher CCI (1.268 (1.196-1.344)), and trauma (1.268 (1.196-1.344)) were positively associated with admission in multivariable analysis, whereas ultrasound in ED (0.450 (0.308-0.658)) and being a nursing home resident (0.444 (0.270-0.728)) were negatively associated.

CONCLUSION

Referred patients were more often admitted. They received more laboratory investigations, ultrasound examinations, and computed tomographies. Difficult decisions regarding the necessity of admission requiring typical resources of EDs may be a reason for PCP referrals.

Synergism of an Urgent Care Walk-in Clinic With an Emergency Department

BACKGROUND

The overutilization of hospital emergency departments by low-urgency patients is seen as a growing problem in health-care delivery, and a variety of solutions are under discussion. We studied the change in utilization of a hospital emergency department (ED) by low-urgency patients after an urgent care walk-in clinic (WIC) was opened in the immediate vicinity.

METHODS

A prospective, single-center pre-post comparative study was carried out at the University Medical Center Hamburg-Eppendorf (UKE). The ED patient collective consisted of adult walk-in patients who presented to the ED between 4 pm and midnight. The "pre" period consisted of August and September 2019, and the "post" period was from November 2019 (after the opening of the WIC) to January 2020.

RESULTS

The study patients consisted of 4765 ED walk-in patients and 1201 WIC patients. 956 (80.5%) of the WIC patients had been referred onward to the WIC after initially presenting to the ED; from this group, 790 patients (82.6%) received definitive care in the WIC. The number of outpatients treated in the ED fell by 37.3% (95% confidence interval [30.9; 43.8]), from 851.5 to 536.7 per month. The most marked decreases were in the areas of dermatology (from 62.5 to 14.3 patients per month), neurology (45.5 to 25), ophthalmology (115 to 64.7), and trauma surgery (211 to 128.7). No decrease was seen in urology, psychiatry, or gynecology. For patients presenting without any referral document, the mean length of stay fell by a mean of 17.6 [7.4; 27.8] minutes from its "pre" value of 172.3 minutes. The rate of patients who left during treatment fell from 76.5 to 28.3 patients per month (p < 0.001).

CONCLUSION

A GP-led urgent care walk-in clinic next door to an interdisciplinary hospital emergency department is a resource-saving treatment option for walk-in patients who present to the emergency department. Most of the patients referred from the ED to the WIC were able to receive definitive care there.
