In more ...The effects of Burnout in healthcare workers (HCW) are experienced by the worker, other staff, the institution and patients under their care on a daily basis. Workplace violence (WPV) has a spectrum of forms. In more extreme forms it generally is low frequency but has high impact when it occurs. Healthcare systems’ efforts to reduce Burnout are more likely to remain sustained since the impact is experienced daily and awareness is increasingly publicized. The efforts to reduce WPV are harder to sustain due to the lower frequency combined with daily competing administrative demands despite best intentions. Could efforts to reduce the overlapping organizational contributions to both HCW Burnout and WPV be a strategy to sustain prevention of WPV while preventing Burnout? A model of overlapping organizational contributions to HCW Burnout and WPV is built from supporting literature. Recommendations are made for leadership and management style interventions. Potential benefits would be higher quality and satisfaction in patient care by means of higher satisfaction in the delivery of care, recruitment and retention of excellent staff, retention of high quality institutional knowledge and reputation.展开更多

Particularly, a home healthcare system is a networked embedded system where the main functions are to control the disease processes and to help patients maintain their independence and maximum level of function within their own homes and communities. It seems to be self-evident to design a system that would support both patients and their healthcare providers in the process of treatment. Nevertheless, little work in integrating embedded devices with intemet for the support of patients have been done to date. In this paper, we show how to design a healthcare system for supporting the management of the conditions of patients with chronic diseases. This system is built around wireless networked embedded devices, and integrates the intemet technology for telemonitoring the patient's health and notifying of doctors if emergency action is required. Also, patients themselves may specify personal alerts for condition-related issues.展开更多

Clinical data are generated both from the documentation of physicians' interactions with the patient and by diagnostic systems. During the care process, a number of different actors and roles (physicians, specialists, nurses, etc.) have the need to access patient data and document clinical activities in different moments and settings. Thus, data sharing and flexible aggregation based on different users' needs have become more and more important for supporting continuity of care at home, at hospitals, at outpatient clinics. In this paper, the authors identify and describe needs and challenges for patient data management at provider level and regional- (or inter-organizational-) level, because nowadays sharing patient data is needed to improve continuity and quality of care. For each level, the authors describe state-of-the-art Information and Communication Technology solutions to collect, manage, aggregate and share patient data. For each level some examples of best practices and solution scenarios being implemented in the Italian Healthcare setting are described as well.展开更多

However, the...With the rapid development of information technology, the increasing use ofmobile digital devices and efforts from the whole society, the healthcareinformation systems (HISs) are moving towards a new era. However, there isstill a lack of clear understanding of the benefits of HIS at the hospital leveland the influential factors for HIS effectiveness. In this study, we propose aresearch framework to explain how HIS implementation improves hospitalperformance. Our results reinforce the positive effect of HIS on hospitalperformance. In particular, we found that HIS implementation increases boththe cost and revenue of the hospitals, but the increasing effect in revenue ismuch bigger than the increasing effect in cost. We also found that althoughboth small and big hospitals benefit from the implementation of HIS, the effectof size is different. Size has a positive effect on hospital performance for smallhospitals but has a negative effect on big hospitals. This indicates that thecompetitive advantage of economies of scale disappears for big hospitalsbecause the level of information transparency becomes lower and transactioncosts become higher as size increases.展开更多

The improvement of treatment efficiency brought by self-monitoring of blood glucose can relieve symptoms and reduce complications,which is considered as the gold standard of diabetes diagnosis and nursing. Compared to the traditional finger pricking measurement with painful and discontinuous processes, continuous blood glucose monitoring(CGM) presents superior advantages in wearable and continuous assessment of blood glucose levels. However, widely used implantable CGM systems at present require implantation operation and are highly invasive, so it is hard to be accepted by users. Except for the blood, available fluids in humans,such as interstitial fluid(ISF), sweat, tears and saliva, also contain glucose associated with blood sugar and can be extracted more easily. Therefore, these more accessible fluids are expected to realize minimized traumatic blood glucose monitoring. This review introduces the latest development of wearable minimally-/non-invasive CGM device, focusing on the types of blood substitute biological fluid and suitable monitoring approaches. We also analysis the merits and drawbacks of each method, and discuss the properties such as sensitivity, stability and convenience of each meter. Beyond highlighting recent key work in this field, we discuss the future development trend of wearable minimally-/non-invasive glucose meters.展开更多

文摘With the rapid development of information technology, the increasing use ofmobile digital devices and efforts from the whole society, the healthcareinformation systems (HISs) are moving towards a new era. However, there isstill a lack of clear understanding of the benefits of HIS at the hospital leveland the influential factors for HIS effectiveness. In this study, we propose aresearch framework to explain how HIS implementation improves hospitalperformance. Our results reinforce the positive effect of HIS on hospitalperformance. In particular, we found that HIS implementation increases boththe cost and revenue of the hospitals, but the increasing effect in revenue ismuch bigger than the increasing effect in cost. We also found that althoughboth small and big hospitals benefit from the implementation of HIS, the effectof size is different. Size has a positive effect on hospital performance for smallhospitals but has a negative effect on big hospitals. This indicates that thecompetitive advantage of economies of scale disappears for big hospitalsbecause the level of information transparency becomes lower and transactioncosts become higher as size increases.
文摘During epidemics,controlling the patients’congestion is a way to reduce disease spreading.Raising medical demands converts hospitals into one of the sources of disease outbreaks.The long patient waiting time in queues to receive medical services leads to more casualties.The rise of patients increases their waste,which is another source of disease outbreak.In this study,a mathematical model is developed to control patients’congestion in a medical center and manage their waste,considering environmental issues.Besides a queueing system controlling the patients’congestion in the treatment center,another queue is considered for vehicles.An inventory model is employed to prevent waste accumulation.The developed model is solved and reaches an exact solution in small size,and obtains an acceptable solution in large size using the Grasshopper algorithm.A case study is considered to demonstrate the model’s applicability.Also,Sensitivity analysis and valuable managerial insights are presented.

文摘Diabetes is one of the most disturbing chronic diseases in the world. The improvement of treatment efficiency brought by self-monitoring of blood glucose can relieve symptoms and reduce complications,which is considered as the gold standard of diabetes diagnosis and nursing. Compared to the traditional finger pricking measurement with painful and discontinuous processes, continuous blood glucose monitoring(CGM) presents superior advantages in wearable and continuous assessment of blood glucose levels. However, widely used implantable CGM systems at present require implantation operation and are highly invasive, so it is hard to be accepted by users. Except for the blood, available fluids in humans,such as interstitial fluid(ISF), sweat, tears and saliva, also contain glucose associated with blood sugar and can be extracted more easily. Therefore, these more accessible fluids are expected to realize minimized traumatic blood glucose monitoring. This review introduces the latest development of wearable minimally-/non-invasive CGM device, focusing on the types of blood substitute biological fluid and suitable monitoring approaches. We also analysis the merits and drawbacks of each method, and discuss the properties such as sensitivity, stability and convenience of each meter. Beyond highlighting recent key work in this field, we discuss the future development trend of wearable minimally-/non-invasive glucose meters.

文摘Mitigating the adverse effects of uncertainty in appointment systems,arising from heterogeneous patient needs and preferences,is critical to the effective use of scarce medical resources and patient satisfaction.This study addresses an online scheduling problem with multiple servers and consideration of patient preference for physicians and their appointment times.The receptionist immediately determines whether a request should be accommodated and offers an appointment time slot for each accepted patient request.The patient may reject an undesirable appointment time slot with a certain probability,or may accept it,but the no-show probability will be higher.A stochastic overbooking model is formulated to maximize the expected profit,which is defined as the revenue generated from accepted requests minus the cost incurred by patients waiting and physicians’overtime.A myopic scheduling policy is developed based on certain structural properties of the objective function.This study advances the study of appointment systems by generating a non-unimodal profit evolution.Moreover,both the decision of accommodating more requests for certain slots and the scheduling of appointments depend on the patient choice rather than the patient type.Further,computational experiments and analysis offer valuable insights into performance improvement in outpatient clinics.
