GUISET is a proposed middleware engine currently under study in South Africa. The goal is to provide utility services for small, medium, and macroenterprises in the context of mobile e-services. Three things are important to make this engine effective and efficient: the implementation, performance, and the pricing strategy. The literature has delved richly into implementation issue of similar projects. Both the performance and the pricing strategy issues have not been fully discussed especially in the context of mobile healthcare services. Some literature has addressed the performance issue using the exogenous nonpriority and the preemptive model. However, with providers offering different services using that approach may prove to be difficult to implement. This work extends existing and widely adopted theories to non-preemptive model by using the queuing theory and the simulation model in the context of mobile healthcare services. Our evaluation is based on non-preemptive priority and nonpriority discipline. Our results reveal that the unconditional average waiting time remains the same with reduction in waiting time over the non-preemptive priority model in four out of the five classes observed. This is envisaged to be beneficial in mobile healthcare services where events are prioritized and urgent attention is needed to be given to urgent events.

Abstract Background Tuberculosis is a top-10 cause of under-5 mortality, despite policies promoting tuberculosis preventive therapy (TPT). We previously conducted a cluster randomized trial to evaluate the effectiveness of symptom-based versus tuberculin skin-based screening on child TPT uptake. Symptom-based screening did not improve TPT uptake and nearly two-thirds of child contacts were not identified or not linked to care. Here we qualitatively explored healthcare provider perceptions of factors that impacted TPT uptake among child contacts. Methods Sixteen in-depth interviews were conducted with key informants including healthcare providers and administrators who participated in the trial in Matlosana, South Africa. The participants’ experience with symptom-based screening, study implementation strategies, and ongoing challenges with child contact identification and linkage to care were explored. Interviews were systematically coded and thematic content analysis was conducted. Results Participants’ had mixed opinions about symptom-based screening and high acceptability of the study implementation strategies. A key barrier to optimizing child contact screening and evaluation was the supervision and training of community health workers. Conclusions Symptom screening is a simple and effective strategy to evaluate child contacts, but additional pediatric training is needed to provide comfort with decision making. New clinic-based child contact files were highly valued by providers who continued to use them after trial completion. Future interventions to improve child contact management will need to address how to best utilize community health workers in identifying and linking child contacts to care. Trial registration The results presented here were from research related to NCT03074799, retrospectively registered on 9 March 2017.

Previous medical services for humans provided healthcare information using the static-based computing of space-constrained hospitals or healthcare centers. In contrast, current mobile health information management computing and services are being provided so that they utilize both the mobility of mobile computing and the scalability of cloud computing to monitor in real-time the health status of patients who are moving. In addition, data capacity has sharply increased with the expansion of the principal data generation cycle from the traditional static computing environment to the dynamic computing environment. This chapter presents mobile cloud healthcare computing systems that simultaneously leverage the portability and scalability of healthcare services. This chapter also presents the wearable computing system as an application of mobile healthcare.

Applications accessible through mobile devices, such as mobile phones, are playing an increasingly important part in the delivery of high quality and personalized healthcare services. In this paper, we examine current usage of mobile devices and networks by mobile healthcare applications, and present our views on how mobile devices and networks could be used for creating patient-centered healthcare applications. The patient-centered healthcare paradigm allows for increased quality of care and quality of life for patients while increasing personal freedom to move about and be always connected to care-givers and healthcare services. The structure of our discussion is analogous to layered protocol stack in communications, progressing from the network and radio technologies, servicing middleware, cloud services, health sensors, mobile smartphones, and applications. All these layers come into play to support future mobile healthcare services.

Abstract Background Adolescent pregnancy and motherhood has been a controversial and much disputed subject within the field of public health. Early childbearing is not only characterized as a physical body experience but also embodies the experiences and perceptions of the social norms, discourses, conflict and moral judgement. There is an increasing concern that the psychosocial challenges facing adolescent mothers remains in the background since research in this field has mainly focused on the medical and physical complications of early childbearing. The aim of this qualitative study was to explore adolescent pregnancy and motherhood in order to understand this phenomenon from the perspective of adolescent mothers and to gain insight into their future aspirations. Methods This descriptive qualitative study was based on data from four focus group discussions with adolescent mothers utilising healthcare services at a district hospital in Ugu district, KwaZulu Natal, South Africa. The data were audio-recorded and transcribed verbatim, then analysed using thematic analysis. Results Some adolescent mothers’ partners were in denial and rejected them and the child while others’ partners were happy and supported them during their pregnancy. Families’ reactions to the pregnancies ranged between anger and disappointment to abandonment, the silent treatment, and acceptance and forgiveness. The psychological issues experienced by some of the adolescent mothers included suicidal ideation, guilt, loneliness, anxiety, and stress. They also experienced financial constraints, difficulty in returning to school, and stigmatisation in society. The participants envisioned completing their education, focusing on their dream careers, and contributing positively to society. Conclusion Experiences of adolescent pregnancy and parenting are multifaceted and the healthcare needs of pregnant and parenting adolescents extend beyond information and knowledge. A multidisciplinary approach is required in the care of adolescent mothers. A key policy priority should encompass the collaboration of different professionals from various healthcare sectors to assist adolescent mothers in achieving better health and psychosocial and socio-economic outcomes as steps to securing a better future for them.

Patient Waiting

The emergency department (ED) plays crucial role in providing 24-hour healthcare services to the ill with speed, accuracy, and sympathy. ED faces the problem of patient waiting time, which leads to patient dissatisfaction and patient crowding. This paper presents a systematic literature review of simulation of ED in healthcare systems from 1970 to 2013. The objectives of this review are to highlight the importance and role of simulation studies to solve the problem of patient waiting time faced by the ED. It also discusses how simulation can be better applied as a tool to solve these problems. The authors found that these simulation studies focus important insights into ED problems, but they also had some limitations that should be addressed.
