An Evaluation Scale of Medical Services Quality Based on “Patients' Experience”

An evaluation scale of medical services quality was developed on the basis of ＂patients＇ experience＂. The questionnaires were developed by, among others, searching relevant literature, col- lecting well-established assessment scales, measuring patients＇ experience and satisfaction, brain-storming, literature analysis. Delphi method was adopted for expert consultation. Scale items were screened and revised. The key indexes were converted. Field surveys were conducted for testing the reliability and validity of the scale. Our modified evaluation scale for measuring medical services quality based on ＂patients＇ experience＂ included 6 dimensions （tangibility, reliability, responsiveness, assurance, empathy and continuity）, and 50 items. The novel scale based on ＂patients＇ experience＂ may better serve the purpose of assessin~ medical services quality.

Heterogeneous Quality of Experience Guarantees Over Wireless Networks

Quality of experience(Qo E), which is very critical for the experience of users in wireless networks, has been extensively studied. However, due to different human perceptions, quantifying the effective capacity of wireless network subject to diverse Qo E is very difficult, which leads to many new challenges regarding Qo E guarantees in wireless networks. In this paper, we formulate the Qo E guarantees model for cellular wireless networks. Based on the model, we convert the effective capacity maximization problem into the equivalent convex optimization problem. Then, we develop the optimal Qo E-driven power allocation scheme, which can maximize the effective capacity. The obtained simulation results verified our proposed power allocation scheme, showing that the effective capacity can be significantly increased compared with that of traditional Qo E guarantees based schemes.

Quality of experience based scheduling algorithm in LTE network with various traffics

Quality of experience （ QoE ） based scheduling algorithm of long term evalution （ LTE ） network with various traffics is studied. Utility functions are adopted to estimate mean opinion score （MOS） for different traffics and a new MOS metric called normalized MOS is defined. A scheduling algorithm based on normalized MOS and greedy algorithm is proposed, aiming at maximizing the entirety MOS level of the whole users in the cell. We compare the performance of the proposed algorithm with other typical scheduling algorithms and the simulation results show that the algorithm pro- posed outperform other ones in term of QoE and fairness.

Assessment of Quality of Experience (QoE) of Web and Video Services over a Mobile Network Using a Network Emulator

This paper investigates the subjective assessment of QoE of web and video services over a mobile network. To achieve this, the authors used the network emulator (NetEm) traffic control functionality to simulate the dynamic behaviour of a mobile network. Experiments were conducted in a laboratory setting and test conditions were varied to ascertain the QoE, with a focus on QoE metrics such as delay and packet loss ratio. From the experiments conducted, it was observed that there was a negative correlation between delay and average mean opinion score (MOS), and between packet loss ratio and average MOS. The results obtained can be adopted by network operators to provide better services which would lead to improved subscriber base and profitability for the operators and better QoE for the end users.

Influences of Network Delay on Quality of Experience for Soft Objects in Networked Real-Time Game with Haptic Sense

In this paper, we investigate the influences of network delay on QoE (Quality of Experience) such as the operability of haptic interface device and the fairness between players for soft objects in a networked real-time game subjectively and objectively. We handle a networked balloon bursting game in which two players burst balloons (i.e., soft objects) in a 3D virtual space by using haptic interface devices, and the players compete for the number of burst balloons. As a result, we find that the operability depends on the network delay from the local terminal to the other terminal, and the fairness is mainly dependent on the difference in network delay between the players’ terminals. We confirm that there exists a trade-off relationship between the operability and the fairness. We also see that the contribution of the fairness is larger than that of the operability to the comprehensive quality (i.e., the weighted sum of the operability and fairness). Assessment results further show that the output timing of terminals should be adjusted to the terminal which has the latest output timing to maintain the fairness when the difference in network delay between the terminals is large. In this way, the comprehensive quality at each terminal can be maintained as high as possible.

The impact of QoS parameters on video QoE are established based on test-bed experiments. Essentially big data is employed as a method to establish a sensible mapping between network QoS parameters and the resulting video QoE. Ultimately, based on the outcome of experiments, recommendations/re- quirements are made for a Big Data-driven QoE model.

Progress in applying patient experience in nursing quality improvement

Background： Improving and sustaining the quality of nursing care is an intractable and persistent challenge. The patient experience of nursing care can give a different perspective on nursing quality and help clinical nursing staff to direct quality improvement. Attempts to identify what is patient experience,the relationship with nursing care, and the application of patient experience in nursing quality improvement practice, in order to provide advices for constructing the quality standards and quality improvement strategies of nursing care.Methods： We conducted a literature review of original research publications. The database platforms Pubmed, Web of Science, China National Knowledge Infrastructure（CNKI） and Wanfang were searched from inception until end of August 2015. After screening retrieved articles, 40 sources（articles and organizational websites） were selected for analysis for the connotation, development and application of patient experience in nursing quality researches.Results： Our study identified several concepts about patient experience, roughly sorted out the development path of patient experience in worldwide and the application of patient experience in nursing quality improvement. It points out four precautions when applying patient experience in nursing quality improvement, which are differentiating patient satisfaction and patient experience, choosing appropriate data collection method and appropriate feedback time, and the last but the most important, applying theories to actual clinical practice.Conclusions： Professional indexes are important to maintain the care quality, but it cannot fully reflect quality of nursing care, which needs patient experience as the supplement. Nursing staffs need to make more efforts to enhance patient＇s nursing care experience, and apply the research results to clinical practice, and finally make patient-centered care come true. For future study, the evaluation system and management strategies about patient experience need to be developed to guide nursing quality improvement.

Outpatient Experience of Human Caring Scale （OEHC-Scale）： Improvement by Delphi Method

Based on the outpatient interview and literature review, the initial framework of the outpatient experience of human caring scale was formed with 9 dimensions of outpatient process. The research aim was to improve the scale by Delphi method. Sixteen experts in medical management, human caring or medical education were invited to evaluate the importance of the dimensions and items of the scale and provided some expertise via filling out the DeLphi consultation questionnaires twice in the consulting round. In the first round, the recovery rate showing the experts＇ positivity was 80%; the coefficient of reliability （Cr） ascertaining the authority of the evaluation was 0.92; the mean and full mark ratios responding the concentration of the evaluation were 2.88-4.94 and 6.25%-93.75% respectively; the coefficients of variation （CV） and the Kendall＇s W determining the concordance of the evaluation were 5.06%-52.15% and 0.21-0.24 respectively. In the second round, the recovery rate was 93.75%; the Cr was 0.93; the mean was 3.93-4.93; the full mark ratios were 26.67%-93.33%; the Kendall＇s W was 0.14- 0.31, the CV was 5.25%-23.61%. Via the two-round Delphi study, the scale that included 10 dimensions and 61 items has been improved. Ten dimensions are pre-hospital medical service, guidance, registration, waiting, diagnosis ＆ treatment, paying, inspection ＆ assay, medicine receiving, therapy/injection/transfusion and global evaluation. It was concluded that Chinese scholars have paid high attention to human caring and outpatient experience. The experts have given high agreements about the dimensions which were established with Chinese outpatient process. The dimensions are different from the similar researches about outpatient experience study. In the future, it is necessary to survey the outpatients to test the construct validity, internal consistency reliability and others of the scale to improve the scale.

Explaining Customer Experience of Digital Financial Advice

The goal of this paper is to analyze the customer experience of digital-driven financial advice systems. It is the objective of this study to develop a cross-cultural model for validating customer experiences of digital financial advice. In doing so, both objective and subjective system aspects have been considered. It is found that experiential subjective system aspects are the most important. Surveys have been conducted in The United Kingdom and The Netherlands. In exploratory factor analysis, five dominant factors were obtained in the UK and six factors in The Netherlands to explain customer experience. Based on the factor scores, multiple regression analysis has been performed to develop the digital customer experience model （DCX model）. This is the first cross-cultural model to evaluate customer experience of financial advice. In an era in which financial institutions and FinTech companies battle for the engagement of customers, the DCX model is the first to fundamentally drive value creation, differentiation, regulation, and future research.

Perceptual Quality Assessment of Omnidirectional Images:Subjective Experiment and Objective Model Evaluation

Virtual reality(VR) environment can provide immersive experience to viewers.Under the VR environment, providing a good quality of experience is extremely important.Therefore, in this paper, we present an image quality assessment(IQA) study on omnidirectional images. We first build an omnidirectional IQA(OIQA) database, including 16 source images with their corresponding 320 distorted images. We add four commonly encountered distortions. These distortions are JPEG compression, JPEG2000 compression, Gaussian blur, and Gaussian noise. Then we conduct a subjective quality evaluation study in the VR environment based on the OIQA database. Considering that visual attention is more important in VR environment, head and eye movement data are also tracked and collected during the quality rating experiments. The 16 raw and their corresponding distorted images,subjective quality assessment scores, and the head-orientation data and eye-gaze data together constitute the OIQA database. Based on the OIQA database, we test some state-of-the-art full-reference IQA(FR-IQA) measures on equirectangular format or cubic formatomnidirectional images. The results show that applying FR-IQA metrics on cubic format omnidirectional images could improve their performance. The performance of some FR-IQA metrics combining the saliency weight of three different types are also tested based on our database. Some new phenomena different from traditional IQA are observed.

Characterizing the patient experience during neoadjuvant therapy for pancreatic ductal adenocarcinoma:A qualitative study

BACKGROUND Neoadjuvant therapy(NT)has increasingly been utilized for patients with localized pancreatic ductal adenocarcinoma(PDAC).It is the recommended approach for borderline resectable(BR)and locally advanced(LA)cancers and an increasingly utilized option for potentially resectable(PR)disease.Despite its increased use,little research has focused on patient-centered metrics among patients undergoing NT,including patient experiences,preferences,and recommendations.A better understanding of all aspects of the patient experience during NT may identify opportunities to design interventions aimed at improving quality of life;it may also facilitate the completion of NT and receipt of surgery,ultimately optimizing long-term outcomes.AIM To understand the experience of patients initiating and receiving NT to identify opportunities to improve neoadjuvant cancer care delivery.METHODS Semi-structured interviews of patients with localized PDAC during NT were conducted to explore their experience initiating and receiving NT.Interviews took place between August 2020 and October 2021.Due to the descriptive nature of the research,questions were open ended.Interviews were conducted over the phone,audio recorded and then transcribed.All interviews were coded by two independent researchers using NVivo 12,iteratively identifying themes until thematic saturation was achieved.An integrative approach to qualitative analysis was used,utilizing both inductive and deductive methods.RESULTS A total of 12 patients with localized PDAC were interviewed.Patients with BR(n=7),PR(n=2),and LA(n=3)cancers participated in the study.All patients indicated that choosing NT was the doctor’s recommendation,while most reported not being familiar with the concept of NT(n=11)and that NT was presented as the only option(n=8).Five themes describing the patient experience emerged:physical symptoms,emotional symptoms,coping mechanisms,access to care,and life factors.The most commonly cited recommendation for improving the experience of NT was improved education before and during NT(n=7).Patients highlighted the need for more information on the rationale behind choosing NT prior to surgery,the anticipated surgery and its likelihood of surgery occurring after NT,as well as general information prior to starting NT treatment.The need for seeing different members of the healthcare team,including ancillary services was also frequently cited as a recommendation for improving the experience of NT(n=5).CONCLUSION This study provides a framework to allow for a better understanding of the PDAC patient experience during NT and highlights opportunities to improve quality and quantity of life outcomes.

Living Kidney Donation – Subjective Experiences of Donors before and Two Years after Donation

Little is known about long-term quality of life of kidney donors. We studied subjective experiences of donors before and two years after kidney donation using in-depth interviews of eleven subjects. Interviews were audiotaped, transcribed, and analyzed by qualitative content analysis (grounded theory). Resulting categories of this process were grouped in order to construct ideal types of subjective experiences after kidney donation. Of our donors, 64% were female, mean age was 40.4 years. Donors reported that they had had no medical problems after donation. Most displayed psychological problems, e. g. difficulties adjusting to the new situation, hypochondriacal complaints, and fear of rejection of the recipient’s kidney. Psychological complaints were particularly troublesome in case of complications of the recipient. All donors wished extended counselling after kidney donation. Identifying problems of kidney donors may be easier when doctors are trained in typical experiences. This may also guide the tailoring of individual psychological interventions.
