[Performance and cost calculation for a university ophthalmological outpatient clinic]. / Leistungs- und Kostenkalkulation für eine universitäre, augenheilkundliche Hochschulambulanz.

BACKGROUND: Outpatient procedures at a university hospital are generally considered to be unprofitable. In the present publication we evaluate the turnover and costs of the university eye outpatient department of the Hannover Medical School (MHH) in terms of a cost unit accounting as well as providing a summary of the workload. MATERIAL AND METHOD: Given the data of the hospital information system (IS-H/i.s.h.med from SAP) and a proprietary software (TimeElement), all patient contacts in the year 2019 were evaluated. The latter software is applied in a standardized manner to record the patient flow of our outpatient service in real time electronically. The total costs consist of personnel, material and room costs including infrastructure of the MHH and are compared to the flat-rate revenues according to the university outpatient contract (HSA) as well as further revenues from internal referral services, self-pay patients, outpatient surgery and cooperation contracts for intravitreal injections (IVOM). RESULTS: With an average full-time equivalent (FTE) headcount of 10.63 assistant physicians, 3.6 specialist physicians, and 21 nonphysicians (plus 4 Federal Volunteer Service, BUFDI) in our policlinic, we have determined €â€¯2,927,022 in personnel costs, including overheads, for the entire year. Including infrastructure (€â€¯524,942), material and equipment costs with overheads and internal cost allocation of €â€¯258.657, the total costs in 2019 resulted in €â€¯3,710,621. In contrast, the total income in 2019 was €â€¯3,524,737 generated through the abovementioned patient segments, resulting in a deficit of €â€¯-185,884 (5%). Our data provide evidence that regular outpatient revenues are insufficient and are mainly balanced by outpatient surgery, IVOMs and self-pay patients. In total, there were 19,453 patient contacts during regular office hours (with 17,305 billable cases). At n = 9943, the majority of the contacts were HSA visits; however, only 82% of the cases could effectively be charged due to multiple visits per quarter. The median total patient attendance was 3.21 h (mean 3.38 h). On average, 78 patient contacts were counted per working day. The analysis with TimeElement unveiled a median of n = 2 physician contacts per patient (mean n = 1.91). The median duration per interaction with a physician was 17.98 min (mean 23.23 min). For diagnostics, we counted a median of n = 2 interactions per patient (mean n = 2.31), with an entire interaction lasting a median of 18.30 min (mean 22.60 min). In total n = 37,363 individual diagnostic procedures were recorded in 2019, with SD-OCT being the primary procedure at n = 10,888. CONCLUSION: The cost/turnover calculation showed a marginal financial loss through our ophthalmological outpatient department. Thus, the costs of a university eye outpatient department in Lower Saxony do not seem to be sufficiently covered by direct outpatient revenues. Maintaining quarterly flat rates for all cases of the outpatient department would require a fee of about €â€¯214 in our setting to remain cost neutral. Currently, the lower flat rates in the HSA area are compensated by other areas. Obviously, the high content-related workload in our setting requires a high personnel expenditure with a considerable personnel cost contribution of nearly 80%.

[Influence of COVID-19 shutdown on the workload of a university eye clinic]. / Einfluss des COVID-19-Shutdowns auf die Arbeitsleistung einer Universitäts-Augenpoliklinik.

BACKGROUND: The outbreak of the novel coronavirus disease 2019 (COVID-19) has led to a significant reduction in the number of patients treated in elective medicine in hospitals in spring 2020. Up until now, there are no corresponding data for university policlinics. MATERIAL AND METHODS: With the help of the data of the clinic's electronic medical record system (IS-H/i.s.h.med from SAP, Cerner Corporation, North Kansas City, MO, United States of America and SAP SE, Walldorf, Germany) and the time recording and management software TimeElement (Hannover Medical School, Hannover, Germany), which was codeveloped at our clinic, all patient contacts of the COVID-19 shutdown were evaluated over a period of approximately 7 weeks from 18 March 2020 to 8 May 2020 and compared with the same period in 2019. In addition, quarterly revenues for the first and second quarters of 2019 and 2020 were put into perspective via SAP. RESULTS: During the COVID-19 period the total number of patient contacts was reduced by 59.5% compared to the previous year. The number of lockdown period cases decreased by 74.8% compared to the same period in 2019. In particular, the university outpatient/self-paying sector recorded the largest number of lost patient contacts with a reduction to 17.2% of the 2019 baseline. The reduced patient contacts and case numbers resulted in a significant financial loss of at least €â€¯218,000. Via TimeElement there was a 69.4% decrease in all special diagnostic services, with visual field examinations in particular also reduced by 75.3%. Optical coherence tomography (OCT) measurements recorded a decrease of 60.3%. Patient tracking revealed a reduction of average patient attendance times by approximately 23% (COVID 19: 145.8 ± 88.8 min versus 189.6 ± 97.2 min in 2019). DISCUSSION: The COVID-19 shutdown caused the work performance of our policlinic to drop to only about 40% of patient contacts and that of functional diagnostic examinations to only about 30%, compared to the performance in 2019; however, the reduction in the number of patients also led to a significant reduction in the time patients were present at the clinic compared to the regular workload. The associated financial losses are considerable and obviously not compensated by legally regulated compensation payments as in the inpatient sector.

Can family attributes explain the racial disparity in living kidney donation?

BACKGROUND: Living donation is a safe, effective treatment for patients with end-stage renal disease (ESRD), yet rates of live kidney donation remain low. Potential transplant recipients may be more inclined to ask a family member for a living donation if they feel familial closeness. METHODS: The FACES II and the Living Organ Donor Survey were administered to patients attending pretransplant education to assess individual perceptions of family structure and willingness to request a living kidney donation from a family member. RESULTS: A total of 328 potential transplant recipients were included in the study: 200 (61%) African American and 128 (39%) Caucasian. Approximately half were willing to ask for a living donation. Individual's perception of family cohesion, adaptability, and type as measured by FACES II showed most families were mid-range with optimal cohesion and adaptability. Family cohesion and adaptability showed no association with being willing to request a live donation, but those single/never married were only half as likely to ask for donation (odds Ratio [OR] 0.51; 95% confidence interval [CI] 0.31-0.86, P = .01). Lower education (beta = -0.49) and unmarried status (beta = -0.31) predicted a lower cohesion score. CONCLUSION: Family type, cohesion, and adaptability showed no differences across race and was not related to the potential recipient's willingness to ask for a live donation. Although responses by race did not differ, an important finding showed that only half of ESRD patients are willing to ask for a live organ donation, and those patients that were single/never married were less likely to ask for a living donation. Research surrounding this reluctance is warranted.

Comparison of ventilatory and haemodynamic effects of BIPAP and S-IMV/PSV for postoperative short-term ventilation in patients after coronary artery bypass grafting.

The aim of the present multiple cross-over study was to compare the effects of biphasic positive airway pressure (BIPAP) ventilation with synchronized intermittent mandatory ventilation combined with pressure support ventilation (S-IMV/PSV) in sedated and awake patients after coronary artery bypass grafting (CABG) surgery. Twenty-four patients with no evidence of preoperative respiratory dysfunction and an uncomplicated intraoperative course were investigated. The patients were randomly assigned to one of two groups starting with either BIPAP or S-IMV/PSV mode. Haemodynamic measurements and blood gas analyses were performed during sedation with 2.0 mg kg(-1) h(-1) propofol in the primary mode, after switching to the alternative ventilatory mode, and in the primary mode again. The same sequence of measurements was repeated in awake patients who had reached extubation criteria. In awake patients, PSV was performed instead of S-IMV. Statistical analysis of data was performed using non-parametric tests. Inspiratory peak pressure increased significantly during S-IMV/PSV in sedated patients in both groups. Other ventilatory parameters did not differ significantly between BIPAP and S-IMV/PSV in both groups. Similarly, haemodynamic parameters and blood-gas analyses did not vary with the ventilatory mode. Our results demonstrate that BIPAP ventilation has comparable effects on haemodynamics and pulmonary gas exchange compared with S-IMV/PSV and PSV when used for short-term ventilatory support in patients after cardiac surgery.

Data warehouse and data mining in a surgical clinic.

Hospitals and clinics have taken advantage of information systems to streamline many clinical and administrative processes. However, the potential of health care information technology as a source of data for clinical and administrative decision support has not been fully explored. In response to pressure for timely information, many hospitals are developing clinical data warehouses. This paper attempts to identify problem areas in the process of developing a data warehouse to support data mining in surgery. Based on the experience from a data warehouse in surgery several solutions are discussed.
