Context The incorporation of high-resolution cameras into smartphones has allowed for a variety of medical applications including the use of lens attachments that provide telescopic, macroscopic, and dermatoscopic data, but the feasibility and performance characteristics of such a platform for use in dermatopathology have not been described. Objective To determine the diagnostic performance of a smartphone microscope compared to traditional light microscopy in dermatopathology specimens. Design A simple smartphone microscope constructed with a 3-mm ball lens was used to prospectively evaluate 1021 consecutive dermatopathology cases in a blinded fashion. Referred, consecutive specimens from the community were evaluated at a single university hospital. The performance characteristics of the smartphone platform were calculated by using conventional light microscopy as the gold standard. The sensitivity and specificity for the diagnosis of melanoma, nonmelanoma skin cancers, and other miscellaneous conditions by the phone microscopy platform, as compared with traditional light microscopy, were calculated. Results For basal cell carcinoma (n = 136), the sensitivity and specificity of smartphone microscopy were 95.6% and 98.1%, respectively. The sensitivity and specificity for squamous cell carcinoma (n = 94) were 89.4% and 97.3%, respectively. The lowest sensitivity was found in melanoma (n = 15) at 60%, although the specificity was high at 99.1%. The accuracy of diagnosis of inflammatory conditions and other neoplasms was variable. Conclusions Mobile phone–based microscopy has excellent performance characteristics for the inexpensive diagnosis of nonmelanoma skin cancers in a setting where a traditional microscope is not available.

This study investigates the linkage between agency costs, ownership structure and corporate governance in small business. Eleven years of data for 100 unlisted small businesses, are collected and 1099 observations are analysed using as dynamic panel GMM estimation. Various diagnostic tests are utilised to check for stationary and convergence of variables. The results indicate that ownership concentration has the most significant governance effect and also has the largest impact on corporate governance. Moreover, this study finds U-shape relationship between internal ownership and performance, which under that agency proxy. Agency costs vary with leverage the life of the business and with its size.

Background: Training maternity nurse regarding cardiopulmonary resuscitation during pregnancy is most important for properly care of such emergency situations during pregnancy and save woman’s and fetal lives.The aim of the present study was to evaluate effect of simulation-based intervention on maternity nurse’ performance regarding cardiopulmonary resuscitation during pregnancy. Design Aquasi-experimental design was adopted in the current study.The study was conducted at woman’s health nursing department training lab at faculty of nursing affiliated at Benha University Hospital. Where a lot of women are admitted for normal and vaginal delivery, gyneacological treatment and surgery.Subjects: A Convenient sample of a total 52 maternity nurses was included.Tools: Two tools: Were used for data collection. Interviewing questionnaire sheet was concerning with nurses personnel characteristics’ and knowledge regarding cardiopulmonary resuscitation during pregnancy and performance check list sheet.the result of the present study that there was a highly statistical difference between knowledge and practical scores of maternity nurse at pre and post intervention. The study concluded that the simulation bases intervention is highly improved maternity nurses’ performance regarding cardiopulmonary resuscitation during pregnancy. The present study recommended that simulation-based training regarding cardiopulmonary resuscitation should be provided for all obstetrics health care givers.

Using Data

AbstractTest indices are often determined by comparing test results of healthy persons with test results of patients known to have the disease. However, the patient population for which the test is ordered in clinical practice often differs from the study population on which the test indices are based. Hence, these indices are not applicable to clinical practice and should be recalculated using data from daily clinical practice. Two major problems of using routinely collected data are discussed: the assessment of the final health status and tracing the reason for ordering the test. Prior considerations are given to the use of hospital information systems (HIS) to sample the patient population that is desired and to collect the necessary data for calculating test indices. We investigated whether the HIS of Leiden University Hospital (which is presented as an example) can be used to calculate the indices of clinical laboratory tests, histopathologic examinations and radiodiagnostic investigations. The results indicate that the registration of diagnoses must be improved and that a way must be found to capture the implicit reasoning for ordering diagnostic tests.

Activity-based costing (ABC) is a method where the costing of the product or service produced is performed on the basis of the activities. This method provides advantages to healthcare managers such as more realistic cost information, elimination of indirect, unnecessary and time-consuming activities and performance measurement. The aim of this study is to examine the applicability of ABC method in health institutions and to compare the calculated costs with the HIN price list. With this aim, the costs of the procedure of IVF center in a university hospital were calculated with the ABC method. Cost calculations for the procedures of Oocyte Pick-Up (OPU), Testicular Sperm Extraction (TESE), Embryo Transfer (ET) and Microinjection as discussed in the study were made with the ABC method and compared against the Healthcare Implementation Notification (HIN) system price lists. The calculated costs were determined according to the effective exchange rate of the dollar. It was revealed that the calculated costs differed from the price list. Finally, the findings suggest that ABC method could provide significant benefit for healthcare managers not only for to understand actual care costs but also to improving the cost control efforts as well as to planning the profitability analysis for hospitals. ABC method would provide a better opportunity and competitive for hospital managers to make a more accurate comparison between their and other health institutions.

Abstract Purpose The described work aimed to avoid cancellations of indispensable treatments by implementing active patient flow management practices and optimizing infrastructure utilization in the radiation oncology department of a large university hospital and regional COVID-19 treatment center close to the first German SARS-CoV‑2 hotspot region Heinsberg in order to prevent nosocomial infections in patients and personnel during the pandemic. Patients and methods The study comprised year-to-date intervention analyses of in- and outpatient key procedures, machine occupancy, and no-show rates in calendar weeks 12 to 19 of 2019 and 2020 to evaluate effects of active patient flow management while monitoring nosocomial COVID-19 infections. Results Active patient flow management helped to maintain first-visit appointment compliance above 85.5%. A slight appointment reduction of 10.3% daily (p = 0.004) could still significantly increase downstream planning CT scheduling (p = 0.00001) and performance (p = 0.0001), resulting in an absolute 20.1% (p = 0.009) increment of CT performance while avoiding overbooking practices. Daily treatment start was significantly increased by an absolute value of 18.5% (p = 0.026). Hypofractionation and acceleration were significantly increased (p = 0.0043). Integrating strict testing guidelines, a distancing regimen for staff and patients, hygiene regulations, and precise appointment scheduling, no SARS-CoV‑2 infection in 164 tested radiation oncology service inpatients was observed. Conclusion In times of reduced medical infrastructure capacities and resources, controlling infrastructural time per patient as well as optimizing facility utilization and personnel workload during treatment evaluation, planning, and irradiation can help to improve appointment compliance and quality management. Avoiding recurrent and preventable exposure to healthcare infrastructure has potential health benefits and might avert cross infections during the pandemic. Active patient flow management in high-risk COVID-19 regions can help Radiation Oncologists to continue and initiate treatments safely, instead of cancelling and deferring indicated therapies.
