Making the health care system 'safe' for persons with HIV infection or AIDS.

If health care reform is implemented in states and nationally, the safety of this process needs to be examined for persons with human immunodeficiency virus (HIV) infection or the acquired immunodeficiency syndrome (AIDS). Reform should assure ongoing prevention and transmission control of HIV and continuous coverage of medical costs for persons ill with HIV or AIDS. These persons currently benefit from various state and federal categoric programs designed to assure access to preventive and personal care services. Washington State has passed health care reform legislation that envisions integrating these programs to provide a system of population-based and personal health care. This legislation was analyzed using existing epidemiologic and entitlement information about persons with HIV infection or AIDS in the state to assess its effect. The relationship between public health and personal care services will be a central concern for those with HIV infection or AIDS, and complete coverage of this group may be achieved relatively late in the process of implementing health care reform. Health personnel planning under health care reform will affect the delivery of HIV- and AIDS-related services. Including treatment of AIDS in the basic benefit package merits particular attention. These issues parallel those being faced by the nation as a whole as it seeks to ensure epidemic disease control and compassionate care for long-term disabling illness if health care reform is implemented.     

Unmet need for additional medical care for sick children in mother's view in rural Bangladesh: implications for improving child health services

While a country's health policy aims to provide health services to all who need them, very little in known about unmet need for additional medical care from users' perspectives in Bangladesh. This study examined unmet medical need (defined as whether a mother felt that, to manage sickness, her child had required medical care that was not available, regardless of reasons and medical care sought) of 2123 under-15 sick children by illness and child's socioeconomic characteristics in rural Bangladesh. The 1996 Health and Socioeconomic Survey conducted in Matlab recorded children's chronic (a disease or a condition lasting 3 months or more) and acute (a disease or a condition with a rapid onset and a short, severe course) morbidity, medical care sought to combat illness and unmet needs for additional medical services in mothers' views to manage the illness. The survey also recorded household socioeconomic data. Logistic regression was used to examine the data. The results reveal that unmet needs for additional medical care were 5.4% for children with acute illnesses, and 30.2% for children with chronic illnesses. For chronic illnesses, seeking medical care to manage illness from any health provider outside the home reduced unmet medical needs. Economic inequalities existed for both acute and chronic illnesses: the odds ratio of unmet medical needs for sick children of the least poor households was 0.42 (95% CI: 0.28-0.64) times that for sick children of the very poor households. The critically high unmet needs for children's chronic morbidity reveal that the chronic disease control programme in Bangladesh needs urgent revisiting and strengthening.     

Equity in the NHS. Monitoring and promoting equity in primary and secondary care.

Although need is often assumed to be the most important factor in determining the use of health services, there are many inequities in the provision and use of NHS services in both primary and secondary care. For example, existing data from district child health information services have been combined with census data for small areas to show wide variations in immunisation rates between affluent and deprived areas. Purchasers of health care are already responsible for assessing health needs and evaluating services, and the process of monitoring equity is a logical extension of these activities. Routine data sources used to collect activity data in both primary and secondary care can be used to assess needs for care and monitor how well these needs are met. Purchasers and providers should collaborate to improve the usefulness of these routine data and to develop a framework for monitoring and promoting equity more systematically.     

Understanding the association between maternal education and use of health services in ghana: exploring the role of health knowledge

Summary This paper examines the role of health knowledge in the association between mothers' education and use of maternal and child health services in Ghana. The study uses data from a nationally representative sample of female respondents to the 2008 Ghana Demographic and Health Survey. Ordered probit regression models evaluate whether women's health knowledge helps to explain use of three specific maternal and child health services: antenatal care, giving birth with the supervision of a trained professional and complete child vaccination. The analyses reveal that mothers' years of formal education are strongly associated with health knowledge; health knowledge helps explain the association between maternal education and use of health services; and, net of a set of stringent demographic and socioeconomic controls, mothers' health knowledge is a key factor associated with use of health services.     

Need, Enabling, Predisposing, and Behavioral Determinants of Access to Preventative Care in Argentina: Analysis of the National Survey of Risk Factors

Introduction

Health care utilization is an important step to disease management, providing opportunities for prevention and treatment. Anderson’s Health Behavior Model has defined utilization by need, predisposing, and enabling determinants. We hypothesize that need, predisposing, and enabling, highlighting behavioral factors are associated with utilization in Argentina.

Methods

We performed a logistic regression analysis of the 2005 and 2009 Argentinean Survey of Risk Factors, a cohort of 41,392 and 34,732 individuals, to explore the association between need, enabling, predisposing, and behavioral factors to blood pressure measurement in the last year.

Results

In the 2005 cohort, blood pressure measurement was associated with perception of health, insurance coverage, basic needs met, and income. Additionally, female sex, civil state, household type, older age groups, education, and alcohol use were associated with utilization. The 2009 cohort showed similar associations with only minor differences between the models.

Conclusions

We explored the association between utilization of clinical preventive services with need, enabling, predisposing, and behavioral factors. While predisposing and need determinants are associated with utilization, enabling factors such as insurance coverage provides an area for public intervention. These are important findings where policies should be focused to improve utilization of preventive services in Argentina.     

Recent Advances in Behavioral Research in Geriatric Dentistry1

This paper examines recent studies in behavioral science and health services aspects of geriatric dentistry. With the increased focus on special needs of older patients, researchers have become concerned with psychological and sociocultural factors that influence older people's oral health status, behavior, and attitudes. Studies of dental service utilization patterns among subgroups of the elderly, including those in long-term care settings, will be reviewed. Research on methods to improve oral health care behaviors will be discussed, with their implications for developing oral health promotion and service delivery programs. The special oral health needs of cognitively impaired and frail elderly will be reviewed. Studies of clinical decision-making in geriatric dentistry have been conducted. These studies have revealed significant gaps in dental professionals' knowledge and attention to the special needs of older patients. This and other aspects of behavioral research suggest the need for better methods to disseminate research findings in geriatric dentistry to clinical practice in this field. The presentation will discuss ways of improving dissemination and transfer of research findings to the clinical management of aged patients.     

Racial/ethnic disparities in infant mortality: the role of behavioral factors

Using the National Maternal and Infant Health Survey 1988 (NMIHS), a nationally representative sample of mothers, we investigate the role of behavioral factors in explaining racial/ethnic disparities in infant mortality. In particular, we focus on the following variables: weight gain during pregnancy, prenatal care utilization, exercise, vitamin use, and substance use during pregnancy. These analyses are conducted by modeling both time of death (neonatal vs. postneonatal) and cause of death (infections, perinatal complications, delivery complications, congenital malformations, SIDS, other causes) outcomes. Our results suggest that behavioral factors are partially responsible for observed race/ethnic differentials in infant mortality, but are not as important as sociostructural determinants such as SES.     

Evaluation of Two Influenza Surveillance Systems in South Africa

Background

The World Health Organisation recommends outpatient influenza-like illness (ILI) and inpatient severe acute respiratory illness (SARI) surveillance. We evaluated two influenza surveillance systems in South Africa: one for ILI and another for SARI.

Methodology

The Viral Watch (VW) programme has collected virological influenza surveillance data voluntarily from patients with ILI since 1984 in private and public clinics in all 9 South African provinces. The SARI surveillance programme has collected epidemiological and virological influenza surveillance data since 2009 in public hospitals in 4 provinces by dedicated personnel. We compared nine surveillance system attributes from 2009–2012.

Results

We analysed data from 18,293 SARI patients and 9,104 ILI patients. The annual proportion of samples testing positive for influenza was higher for VW (mean 41%) than SARI (mean 8%) and generally exceeded the seasonal threshold from May to September (VW: weeks 21–40; SARI: weeks 23–39). Data quality was a major strength of SARI (most data completion measures >90%; adherence to definitions: 88–89%) and a relative weakness of the VW programme (62% of forms complete, with limited epidemiologic data collected; adherence to definitions: 65–82%). Timeliness was a relative strength of both systems (e.g. both collected >93% of all respiratory specimens within 7 days of symptom onset). ILI surveillance was more nationally representative, financially sustainable and expandable than the SARI system. Though the SARI programme is not nationally representative, the high quality and detail of SARI data collection sheds light on the local burden and epidemiology of severe influenza-associated disease.

Conclusions

To best monitor influenza in South Africa, we propose that both ILI and SARI should be under surveillance. Improving ILI surveillance will require better quality and more systematic data collection, and SARI surveillance should be expanded to be more nationally representative, even if this requires scaling back on information gathered.     

Confronting utilization review in New Mexico's Medicaid mental health system: the critical role of "medical necessity"

The insertion of managed care into Medicaid services for the mentally ill has created contention about clinical decision making. At the center of this debate is the matter of what constitutes a medical necessity. Employing ethnographic methodology, this study examines utilization review (UR), the context in which decisions concerning the authorization of mental health care services are made. Interviews carried out in the study contrast ideological underpinnings of providers and advocates of the mentally ill, on the one hand, with employees and administrators of managed care institutions, on the other. The result is an exploration into the ways discourses surrounding the mental health care needs of New Mexico's Medicaid population are being constructed and are determining the actual care they receive.     

Health Service Utilization among Syrian Refugees with Chronic Health Conditions in Jordan

IntroductionThe influx of Syrian refugees into Jordan presents an immense burden to the Jordanian health system, particularly in treating chronic health conditions. This study was undertaken to assess utilization of health services for chronic health conditions among Syrian refugees in non-camp settings.MethodsA survey of Syrian refugees in Jordan was undertaken in June 2014 to characterize health seeking behaviors and issues related to accessing care for hypertension, diabetes, cardiovascular diseases, chronic respiratory diseases, and arthritis. A cluster design with probability proportional to size sampling was used to attain a nationally representative sample of 1550 non-camp Syrian refugee households.ResultsOf 1363 cases with a chronic health condition diagnosis, 84.7% had received care in Jordan. Public facilities faced a heavy burden serving over half (53.9%) of care-seekers; the remainder received care in the private (29.6%) and NGO/charity (16.6%) sectors. Individuals with non-communicable diseases (NCDs) in the central region of Jordan and with arthritis had the lowest rates of care-seeking when compared to other regions and conditions. Overall, 31.6% of care-seekers had an out-of-pocket payment for the most recent care-seeking event which averaged 18.8 USD (median = 0 USD), excluding cost of medications.DiscussionForced displacement presents major challenges to those with NCDs, which have the potential to seriously impact both the quality of life and life expectancy amongst refugees. NCD patterns among Syrian refugees indicate the importance of continuing support to public sector services in Jordan to adequately meet expanding needs and ensure appropriate prevention and control of priority NCDs.     

Comparing Older Adults' Perceived Need for Dental Care with a Normative Hierarchy of Needs1

The elderly are reported to have poor perception of their need for dental care. In a secondary analysis of data from a community interview and clinical examination survey of older adults, we set out to determine the nature and extent of the inconsistency of perceived and normative needs. The data were gathered originally to estimate the oral health status and need for treatment among adults aged 50 and older in East York, Ontario. In the interview, participants responded to four questions dealing with their satisfaction with, and need for, dental care. Dentists conducted clinical examinations following WHO methods which included oral health status and treatment needs. Data were analyzed using SPSSPC +. We placed the clinical needs in order from urgent to no need, following ADA guidelines. The perceptions of subjects were then compared to this normative hierarchy using Kruskal-Wallis analysis of variance. We found that participants' perceptions were closely associated with the normative hierarchy in all comparisons. Our results suggest that the concordance between perceived and normative needs is greater than previously reported.     

HIV disease prevention and treatment. A model for local planning.

Since first reported in 1981, about a fourth of all cases of the acquired immunodeficiency syndrome in the United States have occurred in California. In response to the human immunodeficiency virus (HIV) epidemic, California has developed a five-point strategy consisting of epidemiologic surveillance; prevention education; the provision of medical treatment and supportive services; research; and continuous planning, evaluation, and coordination of programs. Given the size and tremendous environmental and cultural diversity of California, as well as the variable local impact of HIV disease local jurisdictions need to develop HIV disease prevention and treatment plans specifically tailored to the circumstances of their communities. At a minimum, these plans should include central participatory planning, epidemiologic surveillance, HIV antibody testing and prevention education programs, provision for medical treatment and social support services, and coordination of financing mechanisms. We present a model for such plans.     

Comparing sources of mobility for modelling the epidemic spread of Zika virus in Colombia

Timely, accurate, and comparative data on human mobility is of paramount importance for epidemic preparedness and response, but generally not available or easily accessible. Mobile phone metadata, typically in the form of Call Detail Records (CDRs), represents a powerful source of information on human movements at an unprecedented scale. In this work, we investigate the potential benefits of harnessing aggregated CDR-derived mobility to predict the 2015-2016 Zika virus (ZIKV) outbreak in Colombia, when compared to other traditional data sources. To simulate the spread of ZIKV at sub-national level in Colombia, we employ a stochastic metapopulation epidemic model for vector-borne diseases. Our model integrates detailed data on the key drivers of ZIKV spread, including the spatial heterogeneity of the mosquito abundance, and the exposure of the population to the virus due to environmental and socio-economic factors. Given the same modelling settings (i.e. initial conditions and epidemiological parameters), we perform in-silico simulations for each mobility network and assess their ability in reproducing the local outbreak as reported by the official surveillance data. We assess the performance of our epidemic modelling approach in capturing the ZIKV outbreak both nationally and sub-nationally. Our model estimates are strongly correlated with the surveillance data at the country level (Pearson’s r = 0.92 for the CDR-informed network). Moreover, we found strong performance of the model estimates generated by the CDR-informed mobility networks in reproducing the local outbreak observed at the sub-national level. Compared to the CDR-informed networks, the performance of the other mobility networks is either comparatively similar or substantially lower, with no added value in predicting the local epidemic. This suggests that mobile phone data captures a better picture of human mobility patterns. This work contributes to the ongoing discussion on the value of aggregated mobility estimates from CDRs data that, with appropriate data protection and privacy safeguards, can be used for social impact applications and humanitarian action.     

The Impact of Comprehensive Case Management on HIV Client Outcomes

In 1990, New York State instituted Comprehensive Medicaid Case Management, also known as Target Case Management (TCM), for people dealing with multiple comorbid conditions, including HIV. The goal of TCM is to assist clients in navigating the health care system to increase care engagement and treatment adherence for individuals with complex needs. HIV-positive individuals engaged in care are more likely to be virally suppressed, improving clinical outcomes and decreasing chances of HIV transmission. The purpose of this study was to understand the impact of TCM management on outcomes for people with HIV. Data were obtained from Amida Care, which operates not-for-profit managed care Medicaid and Medicare Special Needs Plans (SNPs) for HIV clients. Changes in clinical, cost, as well as medical and pharmacy utilization data among TCM clients were examined between January 2011 through September 2012 from the start of case management enrollment through the end of the study period (i.e., up to 6 months after disenrollment). Additionally, CD4 counts were compared between Amida Care TCM clients and non-TCM clients. Notable findings include increased CD4 counts for TCM clients over the one-year study period, achieving parity with non-TCM clients (i.e., Mean CD4 count > 500). When looking exclusively at TCM clients, there were increases in medication costs over time, which were concomitant with increased care engagement. Current findings demonstrate that TCM is able to achieve its goals of improving care engagement and treatment adherence. Subsequent policy changes resulting from the Affordable Care Act and the New York State Medicaid Redesign have made the Health Home the administrator of TCM services. Government entities charged with securing and managing TCM and care coordination for people with HIV should provide thoughtful and reasonable guidance and oversight in order to maintain optimal clinical outcomes for TCM clients and reduce the transmission of HIV.     

Nuclear medicine in district general hospitals.

Nuclear medicine is a recognised clinical specialty both nationally and internationally. Compared with other countries, it is inadequately developed in Britain, particularly in district general hospitals. To create clinical radioisotope services at district level physicians or radiologists with experience in nuclear medicine need to be trained and appointed. Such appointments would allow facilities to evolve that would provide either a comprehensive nuclear medicine service formed around a physician or an imaging service based on a radiologist. Such units would improve the care of patients at a reasonable recurring cost of 15 pounds--30 pounds per investigation.     

Allocating resources to health authorities: development of method for small area analysis of use of inpatient services.

Every year about 22 billion pounds is allocated to health authorities for hospital and community services in England. The distribution of most of these funds is based on a formula developed to reflect the population''s needs, but the existing formula has been criticised on several grounds. This paper describes the development of a method to determine the health needs for small geographical areas. Data from the hospital episodes statistics and 1991 census together with information on vital statistics and supply of health care facilities were used in the model. Two stage least squares regression was used to identify true indicators of need, and these were entered into a multilevel model to take account of variations in practice in different health authorities. The resulting formula should be more statistically robust and more sensitive to needs than previous approaches.     

Assessing the Impact of Family Planning Advice on Unmet Need and Contraceptive Use among Currently Married Women in Uttar Pradesh,India

Background

Counseling/advice is one of the key interventions to promote family planning (FP) in developing countries, including India. It helps to improve the quality of care and reduce maternal deaths. This paper investigates the continuity of maternal health (MH) service utilization from antenatal care to post-natal care and the impact this service utilization has on contraceptive use and on meeting the demand for family planning among currently married women in rural Uttar Pradesh, India.

Methods and Findings

The study assesses the impact of FP advice on unmet need and contraceptive use by adopting the propensity score matching method. It uses data from the District Level Household Survey (DLHS) (2007–08) that covered 76,147 currently married women (CMW) in the age group 15–44 years in Uttar Pradesh. Results show that the utilization of MH services [Antenatal care (ANC), institutional delivery, Postnatal care (PNC)] and FP advice during ANC and PNC has led to increase in current use of contraception by 3.7% (p<.01), 7.3% (p<.01) and 6.8% (p<.01), respectively. However, a greater utilization of these services has not translated into a reduction of unmet need for contraception at a similar manner.

Conclusion

MH service utilization including FP advice is more effective in increasing current use of spacing methods as compared to limiting methods. Findings support the need for “effective FP advice” interventions to reduce unintended births and unmet need. However, women from Scheduled Caste/Scheduled Tribe communities are less likely to receive MH services. Thus, efforts are required to ensure that currently married women across socio-economic backgrounds have equal opportunity to receive MH services and information on contraceptive use to meet the demand for family planning methods.     

Estimating incidence of the French BSE infection using a joint analysis of both asymptomatic and clinical BSE surveillance data

Bovine Spongiform Encephalopathy (BSE) clinical surveillance data were the main source of information to perform back-calculation of BSE infection incidence. Since 2001, systematic BSE screening tests enhanced the clinical surveillance and allowed to detect some preclinical, i.e. asymptomatic, cases of BSE. We propose a method to incorporate additional information provided by screening tests. It was the first time that a back-calculation model was developed for a full BSE clinical surveillance. In the spirit, our approach resembles what it was done in the Acquired Immune Deficiency Syndrome (AIDS) epidemic to incorporate the Human Immunodeficiency Virus (HIV) diagnosis. Nevertheless, in the BSE epidemic, we had to consider different surveillance systems, their peculiarity, and the phenomenon of communicating vessels between these surveillance systems. In addition, both the preclinical sensitivity of tests and the status of BSE cases, asymptomatic or clinical, were not precisely known. We applied the model to the French BSE epidemic in order to obtain an updated estimate of the incidence of BSE infection. Our back-calculation model fitted very well the observed data of each surveillance system. We detected a lengthening of the incubation period and estimated that the number of infections was very small in the late 1990s and zero in July 2001.     

Beyond Lassa Fever: Systemic and structural barriers to disease detection and response in Sierra Leone

BackgroundLassa fever (LF) often presents clinically as undifferentiated febrile illness. Lassa Fever cases in Sierra Leone have been falling since the 2014–2016 Ebola epidemic. Data from other LF endemic countries suggest that this is not a true reflection of local epidemiological decline, but rather a function of either health seeking behaviour or the health/referral system. In Sierra Leone, many other diseases present with a similar early clinical picture, including COVID-19 and Marburg Disease (which has recently emerged in neighbouring Guinea). This empirical study explores the implementation of health system processes associated with International Health Regulations (IHR) requirements for early detection and timely and effective responses to the spread of febrile disease, through the case study of LF in Sierra Leone.Methodology/Principal findingsThis study used a qualitative approach to analyse local policy and guidance documents, key informant interviews with policy and practice actors, and focus group discussions and in-depth interviews with health care workers (HCWs) and community health workers (CHWs) in Kenema District to examine the ways in which undifferentiated fever surveillance and response policies and processes were implemented in the post-Ebola period. Multiple challenges were identified, including: issues with the LF case definition, approaches to differential diagnosis, specimen transport and the provision of results, and ownership of laboratory data. These issues lead to delays in diagnosis, and potentially worse outcomes for individual patients, as well as affecting the system’s ability to respond to outbreak-prone disease.Conclusions/SignificanceIdentification of ways to improve the system requires balancing vertical disease surveillance programmes against other population health needs. Therefore, health system challenges to early identification of LF specifically have implications for the effectiveness of the wider Integrated Disease Surveillance and Response (IDSR) system in Sierra Leone more generally. Sentinel surveillance or improved surveillance at maternity facilities would help improve viral haemorrhagic fever (VHF) surveillance, as well as knowledge of LF epidemiology. Strengthening surveillance for vertical disease programmes, if correctly targeted, could have downstream benefits for COVID-19 surveillance and response as well as the wider health system—and therefore patient outcomes more generally.
