A family nurse-led intervention for reducing health services’utilization in individuals with chronic diseases:The ADVICE pilot study

Objectives:Intensive health services'utilization is common in older individuals affected by chronic diseases.This study assessed whether a structured family nurse-led educational intervention would be effective in reducing health services'use(readmissions and/or emergency service access)among older people affected by chronic conditions.Methods:This is a non-randomized before-after pilot study.A sample of 78 patients was recruited from two general practices in Italy and 70 among them were followed for 8 months.Standard home care was provided during the first four months'period(months 1-4),followed by the educational intervention until the end of the study(months 5-8).The intervention,based on the teach-back method,consisted of by-weekly 60-min home sessions targeting aspects of the disease and its treatment,potential complications,medication adherence,and health behaviours.Rates of health services'use were collected immediately before(T0),and after the interventions(T1).Differences in utilization rates were examined by the McNemar's test.Potential factors associated with the risk of health services'use were explored with a Cox proportional hazard regression model.Results:The sample(n=78)was predominantly female(n=50,64.1%),and had a mean age of 76.2(SD=4.8)years.Diabetes mellitus was the most frequent disease(n=27,34.6%).McNemar's test indicated a significant reduction in health services'use at T1(McNemar χ^(2)==28.03,P<0.001).Cox regressions indicated that time and patient education,as well as their interaction,were the only variables positively associated with the probability of health services'use.Conclusion:A teach-back intervention led by a family nurse practitioner has the potential to reduce health services'use in older patients with chronic diseases.

Health Services Utilization and Health Status of Insured versus Uninsured Nigerian Children with Sickle Cell Disease

Introduction: Nigeria accounts for 150,000 infants born with the Sickle Cell Disease (SCD) every year. Children with SCD are affected by the deleterious effect of user fees which reduces affordability and utilization of health services. Evidences supported that institutionalized health insurance increases intensity of utilization. Methodology: The study was conducted at AKTH, Kano, and north-western, Nigeria. The study was retrospective comparative cross-sectional study. 100 patients were enrolled, 50 for each arm. Paediatric SCD clinic outpatients’ records and a specialty designed form containing the variables of interest were used. Data were analysed using Minitab 16. Proportions, percentages, tables, charts and chi squared test were used to compare the two groups. Result: The study found no association between the two groups in the likelihood of being insured based on age (χ2 = 1.478), gender (χ2 = 0.224) and dwellings (χ2 = 0.062). On health services utilization and insurance status, the study revealed that follow up clinic visits, unscheduled clinic visits and emergency room visits were more likely among the insured group compared to the uninsured group. While the health status and insurance status of the two groups over 12 months period showed a significant association with the insured more likely to have improved health status compared to uninsured (χ2 = 28.019, p = 0.0001). Similarly, health status and health services utilization were significantly associated with insurance status (χ2 = 12.191, p = 0.002). Conclusion: The insurance status of children with SCD is associated with their health services utilization and health status. However, age, gender and dwellings were not associated with insurance status of children with SCD. Therefore, when expanding insurance coverage (NHIS) among children with SCD considerations have to be given to increase health services utilization and resultant improvement in health status as these have the potential of reducing morbidity and mortality among children with SCD.

Impact of the New Cooperative Medical Scheme on Health Care Service Utilization in Rural China

Using the 2000, 2004, and 2006 CHNS longitudinal survey data and econometric methods （random-effect probit regression model and DID methods）, this study conducted an empirical analysis to estimate the impact of NCMS. The major conclusions are as follows. First, predisposing factors, enabling factors, health care need factors, and lifestyle factors affect health care utilization. Second, results using DID methods indicate that NCMS did not affect health care service utilization （outpatient and inpatient） of individuals when ill, but it might increase the possibility of getting a health examination. Third, there is no difference in health care service utilization （both outpatient and inpatient） between the NCMS enrollment group and the non-enrollment group in both working age group （15-59） and the elderly group （60 and over）. Therefore, it can be said that NCMS did not affect the health care utilization in both the group. However, NCMS positively affects disease prevention behavior （visiting the hospital to receive a health examination） in the working age group, but the effect did not appear in the elderly group.

Improving Demand for Health Services with the Involvement of Community Health Workers: A Case Study of Community Dynamics at Mosango Rural Health Zone in the Democratic Republic of Congo

Introduction: DRC is one of Sub-Saharan Africa country with high infant and maternal mortality. The major problem is the underuse of health services because of inaccessibility on all fronts and also the population under-information to the health and development problems. Community participation is one of the basic requirements and basic principles of the Primary Health Care to solve this problem. That is why we choose Mosango RHZ to assess the improvement of demand for health services with the involvement of community health workers. Methods: We conduct a cross-sectional study carried out in Mosango RHZ in 2019. The study combined a mixed method (quantitative and qualitative) based on the realist evaluation approach which takes into account the Context-Mechanisms-Effects explained in the conceptual framework model. Results: Four predictive factors determine the improvement of health indicators with the involvement of CHWS in activities of the Mosango RHZ: Having attended school (p = 0.000;OR = 0.150);Having sufficient theoretical knowledge on malaria, diarrhoea, pneumonia, malnutrition, availability of inputs to treat these diseases (p = 0.004;OR = 0.192);Having taken the training as CHWS and Having undergone more than one training as CHW (p = 0.013;OR = 0.074). This result corroborated with other studies carried in low- and middle-income countries like DRC. Conclusion: The involvement of CHWs on improving demand for health services is effective in Mosango RHZ. The improvement of health service indicators and the effectiveness of this community intervention were conditioned by capacity building of the CHWs, the availability of inputs and the involvement of the community in the activities of the health zone through the Community Action Cells.

Utilization and Felt Need of Oral Health Care Services among Women in Chennai-Descriptive Cross-Sectional Study

Introduction： Oral health is window to overall health. There is a greatest burden of oral diseases on the underprivileged group. In developing countries like India the affordability to oral health care services is very limited thereby leading to poor oral wellness ＆ millions suffer intractable toothache and poor quality of living and end up with few dentition. Objective： To assess the utilization level of oral health services among women in Chennai. Material and methods： A cross-sectional questionnaire survey was conducted among 200 women in Teynampet Zone in Chennai District, Tamil Nadu. The women were chosen by simple random sampling and were interviewed using the semi-stzuctured questionnaire to assess their utilization level during the period of June to July 2016. The data were analyzed by SPSS Version 22. Result： Descriptive statistics and multivariate analysis--MANOVA were used to analyze the utilization level. Majority of the respondents were in the age group of 30-35years, most of the respondents had oral problem and almost everyone had visited dentist at least once within 3 years. Multivariate analysis--MANOVA also showed that the utilization levels were directly influenced by accessibility, availability and affordability and showed statistical significance （p value 〈 0.05） and also from MANOVA analysis it showed that the respondents who had poor oral hygiene did not utilize oral health care services as the affordability was a problem although accessibility and availability was adequate. Conclusion： Our fmdings suggest that people who had oral problem had visited dentist in previous 3 years and most of the people who visited dentist had a good oral hygiene. Cost of the treatment affected the dental visits. They believed that visiting the dentist is necessary only for pain relief.

Status and determinants of health services utilization among elderly migrants in China

Background:The household registration system in China places migrants in a vulnerable status regarding access to local public services,including limited access to health services.Most studies on migrants’health services utilization targeted on working-age migrants,and there has been a paucity of studies conducted among elderly migrants.This study aims to investigate the status of health services utilization and its influential factors among elderly migrants.Methods:Data(13,043 participants,52.4%male,mean age 66.22±6.20)were derived from the 2015 Migrant Dynamics Monitoring Survey.The outcome variable in the study was health services utilization,consisting of doctor visits,hospitalization and local inpatient care.The Behavioral Model of Health Service Use was applied to categorize the influential factors into three components,including predisposing,enabling and need factors.Multivariate logistic regression analysis was used to investigate the influential factors of the three components of health services utilization.Results:Of the total sample,45.5%would visit a doctor when they were ill,81.8%would prefer to be hospitalized when recommended by doctors,and 71.6%(those who were hospitalized)would choose to receive local inpatient care rather than going back to their hometown.Age,marital status,household income,years of residence,migration range,reasons for migration,size of friend network,health insurance type,local health insurance status and chronic disease status were significantly associated with health services utilization.Conclusion:A low level of local health services utilization was observed among elderly migrants.Enabling factors played important roles in promoting health services utilization among elderly migrants.Policy and decision makers may consider improving the capability for elderly migrants to access health services,such as increasing income and providing local health insurance.

Non-alcoholic fatty liver disease is not associated with a lower health perception

AIM: To examine the association between non-alcoholic fatty liver disease (NAFLD) and general health perception.METHODS: This cross sectional and prospective follow-up study was performed on a cohort of a sub-sample of the first Israeli national health and nutrition examination survey, with no secondary liver disease or history of alcohol abuse. On the first survey, in 2003-2004, 349 participants were included. In 2009-2010 participants from the baseline survey were invited to participate in a follow-up survey. On both baseline and follow-up surveys the data collected included: self-reported general health perception, physical activity habits, frequency of physician’s visits, fatigue impact scale and abdominal ultrasound. Fatty liver was diagnosed by abdominal ultrasonography using standardized criteria and the ratio between the median brightness level of the liver and the right kidney was calculated to determine the Hepato-Renal Index.RESULTS: Out of 349 eligible participants in the first survey, 213 volunteers participated in the follow-up cohort and were included in the current analysis, NAFLD was diagnosed in 70/213 (32.9%). The prevalence of 'very good' self-reported health perception was lower among participants diagnosed with NAFLD compared to those without NAFLD. However, adjustment for BMI attenuated the association (OR = 0.73, 95%CI: 0.36-1.50, P = 0.392). Similar results were observed for the hepato-renal index; it was inversely associated with 'very good' health perception but adjustment for BMI attenuated the association. In a full model of multivariate analysis, that included all potential predictors for health perception, NAFLD was not associated with the self-reported general health perception (OR = 0.86, 95%CI: 0.40-1.86, P = 0.704). The odds for 'very good' self-reported general health perception (compared to 'else') increased among men (OR = 2.42, 95%CI: 1.26-4.66, P = 0.008) and those with higher performance of leisure time physical activity (OR = 1.01, 95%CI: 1.00-1.01, P < 0.001, per every minute/week) and decreased with increasing level of BMI (OR = 0.91, 95%CI: 0.84-0.99, P = 0.028, per every kg/m2) and older age (OR = 0.96, 95%CI: 0.93-0.99, P = 0.033, per one year). Current smoking was not associated with health perception (OR = 1.31, 95%CI: 0.54-3.16, P = 0.552). Newly diagnosed (naive) and previously diagnosed (at the first survey, not naive) NAFLD patients did not differ in their self-health perception. The presence of NAFLD at the first survey as compared to normal liver did not predict health perception deterioration at the 7 years follow-up. In terms of health-services utilization, subjects diagnosed with NAFLD had a similar number of physician’s visits (general physicians and specialty consultants) as in the normal liver group. Parameters in the fatigue impact scale were equivalent between the NAFLD and the normal liver groups.CONCLUSION: Fatty liver without clinically significant liver disease does not have independent impact on self-health perception.

Crohn’s disease in low and lower-middle income countries: A scoping review

BACKGROUND While Crohn’s disease has been studied extensively in high-income countries,its epidemiology and care in low and lower-middle income countries(LLMICs)is not well established due to a lack of disease registries and diagnostic capacity.AIM To describe the published burden,diagnostic/treatment capacity,service utilization,challenges/barriers to individuals with Crohn’s in LLMICs and their providers.METHODS We conducted a scoping review utilizing a full search strategy was developed and conducted in PubMed,Embase and World Health Organization Global Index Medicus.Two independent reviewers screened the titles and abstracts of all of the publications found in this search,reviewed selected publications,and extracted relevant data,which underwent descriptive review and was analyzed in Excel.RESULTS The database search yielded 4486 publications,216 of which were determined to be relevant to the research questions.Of all 79 LLMICs,only 21(26.6%)have publications describing individuals with Crohn’s.Overall,the highest number of studies came from India,followed by Tunisia,and Egypt.The mean number of Crohn’s patients reported per study is 57.84 and the median is 22,with a wide range from one to 980.CONCLUSION This scoping review has shown that,although there is a severe lack of populationbased data about Crohn’s in LLMICs,there is a signal of Crohn’s in these settings around the world.

Study on the Effects of Infant Fostering Interventions in Xuhui District,Shanghai

Objective To assess the effects of fostering interventions on the infants and their families through the community. Methods A total of 309 infants born on 1st August, 2003 to 30th August, 2004 and their families were recruited as participants by cluster sampling in Longhua and Kantian sub-districts of Xuhui district, Shanghai. The newborns were randomly assigned to intervention group （156 cases） and control group （153 cases）. The infants and their families will be followed up during 3-year interventions. Results After 6 months＇ intervention, the proportion of infants who could turn over the body in the intervention group （88.46%） was higher than that in control group （75.16%）. The morbidity of upper-respiratory tract infection in intervention group （20.51%） was significantly lower than that in control group （32.68%）. The incidence rates of pneumonia, diarrhea and anemia in intervention group were all lower than that in control group, except for pneumonia, the differences were not significant. Both of the knowledge about how to foster infants and service utility in intervention group were higher than that in control group. Conclusion The fostering interventions through the community promote the prevention and control of infants disease, increase the knowledge level and service util ity of families.

An Exploratory Study on the Meaning of Using Community Psychiatric Rehabilitation among Persons with Psychiatric Disabilities

This study explores the meaning of the use of community psychiatric rehabilitation(CPR)services to gain knowledge to improve services and shed more light on how to facilitate recovery.The topics explored included:the motivation for participation,perception and expectation towards CPR,the interactions with professionals in the CPR Center,and the feelings towards activities.A qualitative approach was adopted,and 30 consumers were interviewed face-to-face by using semi-structured interview guide.Data were analyzed using the open coding method of grounded theory.The consumer accounts provided information on the eight aspects of CPR services.The findings revealed that the CPR Center created a lifeworld,a friendly place similar to home with structure and activities.Professional relationship was the key change agent for rehabilitation.Most professionals adopted recovery-oriented approach to empower participants by giving opportunities and choices.The essential ingredients of this lifeworld covered rehabilitation goals,physical exercises,psychological impact,social interactions,learning,and economic gains.The services were venues for interpersonal interactions and provided structure for daily life,which helped consumers reach their rehabilitation goals and brought existential meaning to their lives.Yet,the accounts also revealed negative phenomena in the CPR center.Suggestions were made to improve services.

Medical service utilisation, economic burden and health status of patients with rare diseases in China

Many patients with rare diseases not only suffer from more severe conditions but often receive less disease management, which is one significant public health concern globally. Few practice-based surveys focus on the care of patients with rare diseases. In the present study, we aimed to investigate medical service utilization, economic burden and health status of patients with rare diseases in China. A cross-sectional questionnaire survey focusing on patients with rare diseases was conducted. Descriptive analysis was conducted to examine the sociodemographic characteristics, medical service utilization, economic burden and health status. Logistic regression analysis was applied to explore influencing factors of self-rated health. A total of 982 patients with 81 types of diseases were included in this survey. We found that 58.2% of patients experienced misdiagnosis, and 35.2% of the patients were misdiagnosed for at least five times. Moreover, 65.8% of patients traveled to hospitals to seek medical services, and 92.1% of patients paid expenses for their treatment. However, only 1.3% of patients could afford their medical expenditure without debts, and 86.8% of patients regarded their health status as bad or moderate. Significant factors correlated with health status were economic status, gender, age, employment and household size. From this study, the accessibility of medical service utilization, the affordability of medical economic burden, and the condition of health status for patients with rare disease in China were considerably poor. Basic medical insurance did not play its role in improving the utilization of medical services and the affordability of medical costs. Social support should be encouraged to improve patients＇ health status.

Effects of New Rural Cooperative Medical Scheme on Medical Service Utilization and Medical Expense Control of Inpatients： A 3-year Empirical Study of Hainan Province in China

Background： The New Rural Cooperative Medical Scheme （NCMS） has been further adjusted and optimized to reduce the financial burden of rural residents and to achieve universal coverage for them. In this study, we aimed to explore the impact of NCMS on medical service utilization and medical expense of inpatients in recent years. Methods： The research data of Hainan Province were extracted from the Chinese NCMS platform from 2012 to 2014. Detailed information included total expenditure, average inpatients costs, average out-of-pocket payments, actual reimbursement rate, and average annual growth rate of the above indicators. Descriptive analysis was used to gauge the effects of NCMS. Results： In the utilization of medical services, NCMS inpatients in tertiary hospital decreased from 25.49% in 2012 to 20.39% in 2014, inpatients in county hospitals increased from 39.49% to 55.92%, simultaneously. The total expenditure in county hospitals rose steadily from 28.46% to 46.66%, meanwhile, the total expenditure in tertiary hospitals fell from 60.44% to 44.51%.The average out-of-pocket costs of rural inpatients remained stable over the years. Furthermore, the compensation fund ofNCMS inpatients grew significantly. The actual inpatient reimbursement rate at township health centers increased from 76.93% to 84.04%. Meanwhile, the rate at county hospitals and tertiary hospitals increased slightly from 59.37% and 46.10% to 61.25% and 47.71%, respectively. Conclusions： With the improvement of the reimbursement ability, especially after the new health care reform in 2009, the NCMS have been playing a prominent role in alleviating the economic burden of farmers＇ medical treatment. Meanwhile, more patients go to primary hospitals than tertiary hospitals, and the capability of primary hospitals has been greatly improved.

Equity of health service utilization of urban residents： data from a western Chinese city

Background Getting medical treatment is still difficult and expensive in western China. Improving the equity of basic health services is one of the tasks of the new healthcare reform in China. This study aimed to analyze the parallel and vertical equity of health service utilization of urban residents and then find its influencing factors. Methods In August 2011, a household survey was conducted at 18 communities of Baoji City by multi-stage stratified random sampling. Based on the survey data, we calculated a concentration index of health service utilization for different income residents and a difference index of different ages. We then investigated the influencing factors of health service utilization by employing the Logistic regression model and log-linear regression model. Results The two-week morbidity rate of sampled residents was 19.43%, the morbidity rate of chronic diseases was 21.68%, and the required hospitalization rate after medical diagnosis was 11.36%. Among out-patient service utilization, the two-week out-patient rate, number of two-week out-patients, and out-patient expense had good parallel and vertical equity, while out-patient compensation expense had poor parallel and vertical equity. The inpatient service utilization, hospitalization rate, number of inpatients, days stayed in the hospital, and inpatient expense had good parallel equity, while inpatient compensation expense had poor parallel equity. While the hospitalization rate and number of inpatients had vertical equity, the days stayed in hospital, inpatient expense, and inpatient compensation expense had vertical inequity. Conclusions Urban residents＇ health was at a low level and there was not good health service utilization. There existed rather poor equity of out-patient compensation expense. The equity of inpatient service utilization was quite poor. Income difference and the type of medical insurance had great effects on the equity of health service utilization.

The Service Utility Model in Service Management

Aiming to provide a measurable service Quality of Service （ QoS） evaluating method for service inventory management, this paper proposes a new mobile Service Utility Model （SUM）, considers the service and business layer elements into the service utility influence profile, and proposes an self-adaptive service inventory management algorithm as a QoS control scheme based on SUM. It can be concluded from the simulation result that the service inventory utility can be fully reflected by SUM and the whole system efficiency is greatly increased by using SUM as the adaptive rule.

Assessing building’s post-earthquake functional recovery accounting for utility system disruption

Experience from past earthquakes has demonstrated the need to account for design goals beyond safety,known as functional recovery objectives,in the interest of community resilience.Frameworks have been proposed in the literature to assess the post-earthquake functional recovery of a building,but without accounting for utility systems’disruption,which may be a key contributor to determining when a building is functional.This paper integrates a previously proposed probabilistic method for estimating the post-earthquake restoration of critical utility services with an individual building’s functional recovery assessment framework.The integration was performed by incorporating utilities into the building system fault trees embedded into a functional recovery framework for various building occupancies(residential and commercial office buildings).Once incorporated,the results are used to interrogate the functional recovery of a reinforced concrete building,and the recovery time results were presented for seven cases investigating contributing factors in the functional recovery results including the number of crews available for lifeline restoration,the effect of low-quality service on meeting tenant requirements for elevators,heating ventilation and air conditioning(HVAC),plumbing and electrical systems,consideration of fire watch,the effect of building seismic retrofit,as well as different cases of fragility functions for the lifeline systems.Results showed that utility systems’disruption does not have a significant impact on the recoccupancy of a building because only one utility-dependent building system(fire suppression)is needed for the building’s safety.Unlike reoccupancy,utility systems are significant for functional recovery,mainly at moderate hazard levels because,at these levels,lifeline networks could be damaged without significant building damage,such that the lifeline systems restoration governs.Buildings with more restrictive tenant requirements are more sensitive to tenant disruptions.

Elimination of schistosomiasis requires multifactorial diagnostics: evidence from high- and low-prevalence areas in the Nile Delta, Egypt

Background:Schistosomiasis is one of the neglected tropical diseases(NTDs)selected for worldwide elimination in the near future.Egypt has made strong progress against its two endemic species of Schistosoma mansoni and S.haematobium.The former is prevalent in the Nile Delta with the latter dominating in the Nile south of Cairo.Innovative efforts are needed to reach the goal as further reduction of the prevalence has stalled due to ongoing transmission.In this study we aimed to explore the difference between low and high prevalence villages with regard to knowledge attitude and practice about schistosomiasis,utilization of health services,infection and transmission indices.Methods:A hybrid cross-sectional longitudinal study was conducted with three annual follow-ups conducted during 1994-1996.We used a representative systematic random sampling technique investigating 993 individuals from the high prevalence village and 614 from the low prevalence village.Data were analyzed using SPSS,comparing proportions with the Chi square test and means with the Student t test,and ANOVA.Results:Compliance of faecal sampling and chemotherapy was above 70%in both villages over the whole study period.Selective praziquantel treatment resulted in a significant reduction of prevalence and intensity of infection in both villages,dropping from 35.8%prevalence to 20.6%,in the low-prevalence village,and from 69.5 to 45.9%in the high-prevalence one.Intensity of infection at the base line was 30 eggs per gram(EPG)of stool in the low-prevalence village versus 105 EPG in the high-prevalence village.However,after the second round,reinfection rebounded by 22%in the high-prevalence village,while a slight improvement of the infection indices was demonstrated in the low-prevalence one.The level of knowledge was modest in both villages:people knew about self-protection and treatment,but not much about the role of human excreta for schistosomiasis transmission.While all participants maintained that using the water from the canals was inevitable,inhabitants in the high-prevalence village showed significantly lower scores reflecting higher water contact compared to the low-prevalence one.Many of them(67%)did not utilize the health centre at all compared to 26%of the people in the low-prevalence village.Interestingly,private clinics were seen as the primary source of health care by both villages,but more frequently so in the high-prevalence village(used by 87.2%of the inhabitants)compared to the low-prevalence one(59.8%).Conclusions:Even if chemotherapy works well as reflected by the observed downregulation of intensity of infection in both villages,reinfection continued due to difficulties to avoid water contact.Efforts must be made to make people understand the role of human excreta for transmission.There is also a need to make people better trust the medical services available.
