Objective: To review, categorise, and synthesise findings from literature on health information technology (HIT) functionalities, HIT use, and the impact of HIT on hospital performance. Materials and Methods: We conducted a systematic integrative literature review based on a compre-hensive database search. To organise, categorise and synthesise the ex-isting literature, we adopted the affordance actualization theory. To align the literature with our research framework, we used four categories: 1) the functionalities of HIT and how these functionalities are measured;2) use and immediate outcomes of HIT functionalities;3) different perfor-mance indicators and how HIT functionalities affect them;and 4) what hospital characteristics influence the outcome of hospital performance. Results: Fifty-two studies were included. We identified four types of HIT. Only ten studies (19.2%) define the use of HIT by explicitly meas-uring the use rate of HIT. We identified five dimensions of hospital per-formance indicators. Every dimension showed mixed results;however, in general, HIT has a positive impact on mortality and patient readmis-sions. We found several hospital characteristics that may affect the rela-tionship between HIT and hospital-level outcomes. Discussion: Further efforts should focus on embedded research on HIT functionalities, use and effects of HIT implementations with more performance indicators and adjusted for hospital characteristics. Conclusion: The proposed framework could help hospitals and researchers make decisions regard-ing the functionalities, use and effects of HIT implementation in hospi-tals. Given our research outcomes, we suggest future research opportuni-ties to improve understanding of how HIT affects hospital performance. . 展开更多

We describe the case of a 73-year-old man with left shoulder paresis caused by a herpes zoster infection of the left C5 dermatomes. The patient had been affected by pain for 10 days, a skin rash on his left shoulder and back for 5 days, and weakness of his left shoulder for 2 days before admission. Eiectromyography revealed denervation discharges from the left supraspinatus, infraspinatus and deltoid muscles, which was compatible with radiculopathy showing after zoster infection. The patient was examined in accordance with the International Classification of Functioning, Disability and Health, and treated with range-of-movement and strengthening exercises as well as activities of daily living and social participation. At 14 months after the onset of the condition, muscle strength had returned to normal. Electromyography revealed that motor unit action potentials were largely normal. These results indicate that the rehabilitation of paresis caused by herpes zoster can obtain positive results with suitable movement training. 展开更多

Patient involvement in the health care process has been documented as a critical component of successful disease management. However, inadequate functional health literacy among patients is a well-known barrier to effective doctor-patient communication, which has an adverse effect on health outcomes. This study aimed at investigating the association of functional health literacy and doctor-patient communication among HIV/AIDS patients in Homa Bay County, Kenya. It was a cross-sectional hospital-based survey conducted among 362 HIV/AIDS patients receiving care at the eight sub-county hospitals of Homa Bay county. Data was collected using a self-administered structured questionnaire. Cronbach’s alpha and confirmatory factor analysis tests were used to ascertain the reliability and validity of study instruments, while Logistic regression logistic analysis was used to measure the association between functional health literacy and doctor-patient communication. 51% of the respondents were females, and the majority (30.9%) of respondents fell in the age group of 45 years and above. The respondents’ functional health literacy levels were inadequate at weighted means scores of 3.23 [SD 1.31]. The study further established that functional health literacy significantly influenced doctor-patient communication [Nagelkerke R square = 0.318]. There is, therefore, a need to document the determinants of functional health literacy to improve it and make doctor-patient interaction an enjoyable and meaningful experience. 展开更多

Introduction: Brazil leads the production of sugarcane and its derived commodities, sugar and ethanol. The fact that it is predominantly manually harvested exposes the workers to a variety of health hazards. Since the harvest is a labor activity that exacts from the worker a heavy physical toll, involving the exertion of quick, repetitive movements that intensely overburden both one’s muscles and skeletal frame. Objective: To assess the health profile and functional independence in former workers who operated in a biofuel plant in Bahia. Methods: This is a descriptive, exploration-oriented study conducted with 42 workers formerly employed as cane cutters, both male and female and over 18 years old, all of them living in the town of Amélia Rodrigues (BA). The self-administered Nottingham Health Profile (NHP) was used to measure their quality of life, based on the World Health Organization’s classification of disabilities;the Functional Independence Measure (FIM) metrics was employed to keep track of functional independence. The FIM focuses on two aspects, motile and cognitive, subdivided further into categories designed to assess individual independence in tackling basic activities effectively and satisfactorily. Results: 42 individuals were assessed, most of them men (54.8%), predominantly adults (73.8%) of African descent (61.9%). Evidence, along with the correlation coefficient to analyze the FIM and the NHP, presents a significance level of 0.05 in the categories: Total NHP, Energy Level, Pain and Physical Abilities. Conclusion: This study found that there is harm to the health of former cane cutters as far as their sleep, energy levels and physical abilities are concerned. With these remarks, the authors expect to motivate health surveillance efforts regarding the risks in those work environments and the associated health issues, so that preventive and interventive public health measures can be implemented. 展开更多

AIM To determine the relationship between chronic kidney disease(CKD) awareness(CKD-A), self-management behaviors(CKD-SMB) knowledge, performance of CKDSMBs, health literacy(HL) and kidney function. METHODS Participants were eligible patients attending an outpatient nephrology clinic. Participants were administered: Newest Vital Sign to measure HL, CKD self-managementknowledge tool(CKD-SMKT) to assess knowledge, past performance of CKD-SMB, CKD-A. Estimated GFR(e GFR) was determined using the MDRD-4 equation. Duration of clinic participation and CKD cause were extracted from medical charts. RESULTS One-hundred-fifty patients participated in the study. e GFRs ranged from 17-152 m L/min per 1.73 m2. Majority(83%) of respondents had stage 3 or 4 CKD, low HL(63%), and were CKD aware(88%). Approximately 40%(10/25) of patients in stages 1 and 2 and 6.4%(8/125) in stages 3 and 4 were unaware of their CKD. CKD-A differed with stage(P < 0.001) but not by HL level, duration of clinic participation, or CKD cause. Majority of respondents(≥ 90%) correctly answered one or more CKD-SMKT items. Knowledge of one behavior, "controlling blood pressure" differed significantly by CKD-A. CKD-A was associated with past performance of two CKD-SMBs, "controlling blood pressure"(P = 0.02), and "keeping healthy body weight"(P = 0.01). Adjusted multivariate analyses between CKD-A and:(1) HL; and(2) CKD-SMB knowledge were nonsignificant. However, there was a significant relationship between CKD-A and kidney function after controlling for demographics, HL, and CKD-SMB(P < 0.05). CONCLUSION CKD-A is not associated with HL, or better CKD-SMBs. CKD-A is significantly associated with kidney function and substantially lower e GFR, suggesting the need for focused patient education in CKD stages 1. 展开更多

In China, with the restructuring of health care system moving forward, private community health facilities have been playing a complementary but increasingly important role in providing public health and basic medical care services in urban areas. However, only limited evidence is available con-cerning the service functions of private community health facilities in China. The aim of this study was to explore the functions of private community health stations (PCHSs) to provide evidence-based rec-ommendations for policy-making and practice in the development of urban community health services systems. A total of 818 PCHSs and 4320 government-sponsored community health stations (GCHSs) located in 28 cities of China were investigated in 2008. The percentages of stations that provided health services and the annual workload per community health worker (CHW) were compared between the two types of institutions. The results showed that the percentages of PCHSs providing public health services were significantly higher than those of GCHSs (P<0.05); but no significant differences were found in the percentages of basic medical services providing between PCHSs and GCHSs (P>0.05). The annual workloads of all the public health services and basic medical services per CHW in PCHSs were lighter than those in GCHSs (P<0.05), except for resident health records establishment and health education materials distribution (P>0.05). At present, the GCHSs are still the mainstream in urban China, which will last for a long period in future. However, our findings showed that the annual workloads of CHWs in PCHSs were no heavier than those in GCHSs, and the PCHSs were willing to provide public health services. In view of current inadequacy of health resources in China, it is feasible to further develop PCHSs under the guidance of the government, given that PCHSs can perform the basic functions of community health services, which is useful for the formation of public-private partnerships (PPP) and the improvement of community health services. 展开更多

Objective: Gastrointestinal (GI) discomfort is experienced by millions of people every day. This study aimed to evaluate the effect of PhenActiv<sup>TM</sup>, a novel green kiwifruit extract, on gastrointestinal tract (GIT) function in otherwise healthy adults. Methods: 41 healthy adults with mild GI discomfort were enrolled in this double-blind, randomized, placebo-controlled study. Participants were randomized to either take 3.0 g/day of PhenActiv<sup>TM</sup> or a placebo for 6 weeks. Interviews were conducted at baseline, week 3 and week 6, with participants completing questionnaires regarding GI symptoms. Frequency of bowel movements was self-recorded daily. Results: There were no differences in daily and weekly defecation frequency and stool characteristics in either group. The active and placebo groups significantly improve GSRS scores (p , only the active group had a significant improvement in the IBSSS and PAC-QOL scores (p < 0.05) from baseline. Neither group had changes in sleep quality, quality of life and fatigue, plasma zonulin concentrations or macular pigment optical density scores. The product was well tolerated with no GI disturbances or adverse events being reported. Conclusion: Supplementation of 3.0 g/day of PhenActiv<sup>TM</sup> for 6 weeks did not improve defecation frequency or stool composition in healthy adults, but did improve perceived symptoms of GIT function, including symptoms of functional GIT disorders, IBS and constipation. The product was well tolerated and future trials investigating higher doses with more participants and/or a different population would be beneficial. 展开更多

The increase in chronic diseases in childhood highlights the need for a biopsychosocial approach to deal with the complexity of these health conditions. The International Classification of Functioning, Disability, and Health (ICF) results from the need to implement new explanatory evaluative and therapeutic models. Thus, the present systematic review aims to identify published studies on the use of the ICF in chronic childhood diseases. As a secondary objective, to map the themes that have already been studied in the area to support the discussion on the expansion of the use of this classification in health services. The systematic review followed the PRISMA protocol, and the model was the PICO acronym, where Population was children and adolescents with chronic diseases, Intervention/Exposure was evaluation based on ICF concepts, Comparator was any tool, instrument, or intervention, and outcome was direct or indirect use of the ICF. We selected eight articles, five of which used the ICF as a conceptual tool and three as a classification system, divided into the following themes: quality of life, evaluation of patients (without using coding) and mapping the inclusion of the activity’s results and participation in clinical trials. Thus, use of the ICF in clinical practice is still incipient, although it has been recommended in guidelines. Further studies are necessary to expand the number of contributions by the ICF and to develop the necessary approaches for understanding the classification’s use. 展开更多
