Adherence to HIV and TB Care and Treatment,the Role of Food Security and Nutrition

Food security and nutrition play an important role in HIV and TB care and treatment, including for improving treatment outcomes, adherence and uptake of HIV and TB care. This AIDS and behaviour supplement on “Adherence to HIV and TB care and treatment, the role of food security and nutrition” provides an overview of the current evidence and knowledge about the barriers to uptake and retention in HIV and TB treatment and care and on whether and how food and nutrition assistance can help overcome these barriers. It contains nine papers on three topic areas discussing: (a) adherence and food and nutrition security in context of HIV and TB, their definitions, measurement tools and the current situation; (b) food and nutrition insecurity as barriers to uptake and retention; and (c) food and nutrition assistance to increase uptake and retention in care and treatment. Future interventions in the areas of food security, nutrition and social protection for increasing access and adherence should be from an HIV sensitive lens, linking the continuum of care with health systems, food systems and the community, complementing existing platforms through partnerships and integrated services.     

The Secret to Health Information Technology's Success within the Diabetes Patient Population: A Comprehensive Privacy and Security Framework

Congress made an unprecedented investment in health information technology (IT) when it passed the American Recovery and Reinvestment Act in February 2009. Health IT provides enormous opportunities to improve health care quality, reduce costs, and engage patients in their own care. But the potential payoff for use of health IT for diabetes care is magnified given the prevalence, cost, and complexity of the disease. However, without proper privacy and security protections in place, diabetes patient data are at risk of misuse, and patient trust in the system is undermined. We need a comprehensive privacy and security framework that articulates clear parameters for access, use, and disclosure of diabetes patient data for all entities storing and exchanging electronic data.     

Optimizing the Potential for Telehealth in Cardiovascular Care (in the Era of COVID-19): Time Will Tell

Before the coronavirus disease 2019 (COVID-19) pandemic, use of telehealth services had been limited in cardiovascular care. Potential benefits of telehealth include improved access to care, more efficient care management, reduced costs, the ability to assess patients within their homes while involving key caretakers in medical decisions, maintaining social distance, and increased patient satisfaction. Challenges include changes in payment models, issues with data security and privacy, potential depersonalization of the patient-clinician relationship, limitations in the use of digital health technologies, and the potential impact on disparities, including socioeconomic, gender, and age-related issues and access to technology and broadband. Implementation and expansion of telehealth from a policy and reimbursement practice standpoint are filled with difficult decisions, yet addressing these are critical to the future of health care.     

Effect of a security system on violent incidents and hidden weapons in the emergency department

STUDY OBJECTIVE: To determine the number of weapons confiscated and assaults reported in an urban county emergency department before and after the implementation of a security system. METHODS: This is a retrospective review of security records for a 54-month period from 1992 to 1996. We determined the number of weapons and assaults before and after the implementation of a security system consisting of metal detectors, cameras, limited access, and a manned security booth at the ED entrance. We calculated the rates of weapons confiscated and assaults per 10,000 ED patients treated. RESULTS: Twenty-four weapons were confiscated before the implementation of the security system, and 40 were confiscated after the implementation ( P<. 001). The percentage of weapons confiscated in the patient care area decreased from 92% to 42% after the security system was installed (P<.001). Seven of the 17 weapons (41%) found in the patient care area after implementation were brought in by ambulance patients who bypassed the security booth and metal detector. The reported assaults per 10,000 patients, however, did not change significantly. CONCLUSION: The implementation of an ED security system increased the number and percentage of weapons confiscated before patients were placed in patient care areas, but did not decrease the number of assaults. This emphasizes the importance of continued training of ED personnel in the management of violent patients and potentially violent situations.     

Implementing context and team based access control in healthcare intranets

The establishment of an efficient access control system in healthcare intranets is a critical security issue directly related to the protection of patients' privacy. Our C-TMAC (Context and Team-based Access Control) model is an active security access control model that layers dynamic access control concepts on top of RBAC (Role-based) and TMAC (Team-based) access control models. It also extends them in the sense that contextual information concerning collaborative activities is associated with teams of users and user permissions are dynamically filtered during runtime. These features of C-TMAC meet the specific security requirements of healthcare applications. In this paper, an experimental implementation of the C-TMAC model is described. More specifically, we present the operational architecture of the system that is used to implement C-TMAC security components in a healthcare intranet. Based on the technological platform of an Oracle Data Base Management System and Application Server, the application logic is coded with stored PL/SQL procedures that include Dynamic SQL routines for runtime value binding purposes. The resulting active security system adapts to current need-to-know requirements of users during runtime and provides fine-grained permission granularity. Apart from identity certificates for authentication, it uses attribute certificates for communicating critical security metadata, such as role membership and team participation of users.     

Health Care for Older Persons in Colombia: A Country Profile

Colombia is a country of approximately 42 million inhabitants, with some 2.5 million being aged 65 and older. Currently, life expectancy in Colombia is 72.3. By 2025, the population life expectancy at birth will be 77.6 for women and 69.8 for men. The quality of care that people receive as they age in Colombia varies according to where they live. Individuals living in the highly urbanized areas of Colombia receive high-quality care, whereas elderly subjects living in rural areas and in the southern and northern regions are exposed to unemployment, low income, inequity of access to health care, drug trafficking, and armed conflict. In spite of these problems, characteristics of aging of older people in terms of functionality and healthcare access are similar to those of people living in developing countries around the world. This article reviews the particular characteristics of the elderly population in Colombia, especially the significant changes that have happened in recent years, when social instability and conflict have determined that health resources be redirected to other budget priorities such as defense and security.     

Concordance facilitates access in diabetes care—service provider perspectives of service improvement and cultural competency

Aims Inequalities between different ethnic groups in diabetes care and outcomes are well documented in the UK. This research sought to explore and understand how national and local policy interventions impacted upon access and the development of culturally competent diabetes services from the care provider perspective. Methods This paper describes the care provider perspective of access to diabetes care in ethnically mixed populations from a thematic analysis of 14 semi‐structured interviews conducted with professionals, at three study sites, with different roles in the diabetes care pathway. Results National policy level initiatives to improve quality have led to quality improvements at a practical level. These achievements, however, have been unable to address all aspects of care that service providers identified as important in facilitating access for all patient groups. Concordance emerged as a key process in improving access to care within local systems and barriers to this exist at different levels and are greater for some groups of patients compared with others. Conclusions Concordance is a key concept that underpins access and cultural competency in diabetes service improvement. A focus on concordance at different levels within local systems may improve access to quality diabetes care for ethnic minority groups.     

Innovations in access to care: a patient-centered approach

To receive health care, patients with nonemergent problems must gain access to a complex, interdependent ambulatory care system currently structured around the conventional office appointment model. The system does not effectively accommodate diverse patient needs and preferences, contributing to both overuse and underuse of health care resources. A patient-centered access model would help patients secure appropriate and preferred medical assistance when and where it is needed. Characteristics of patient-centered access include availability, appropriateness, preference, and timeliness. One or more of these characteristics often is missing in patients' health care experiences. The goal of this paper is to present patient-centered access as an integrated concept and philosophy to provide context for evaluating specific access initiatives. On the basis of an assessment of existing literature, 3 organizing principles of patient-centered access are proposed and discussed: work at the high end of expertise; align care with need and preference; and serve when service is needed. Patient-centered access warrants serious consideration, given the stakes involved for patients, providers, and payers. Few concepts support all 6 of the Institute of Medicine's aims for the 21st century: safety, effectiveness, patient-centeredness, timeliness, efficiency, and equitability. Patient-centered access is such a concept.     

Rural-urban gaps in health care utilization among older Thais: The role of family support

This study examined rural-urban differences in health visits among older Thais utilizing Andersen’s model. Data were drawn from the 2011 Survey of Older Persons in Thailand of adults 50 years and older (N = 56,435). Logistic regression models examine individuals’ predisposing, enabling, and health need factors for explaining older adults’ health care use. Approximately 50% of older adults sought health care but urban dwellers were more likely than rural dwellers to seek health care (54.8% vs. 49.7%). Predisposing factors and health needs narrow the rural-urban gap while enabling factors widened the gap in health visits. The receipt of financial support from children presented a significant moderating effect in the rural-urban divide of health care use. Despite Thailand’s universal access to health care, geographic inequity in health care utilization withstands. Findings suggest investments in education, income security, social participation, and healthy lifestyle promotion can improve health care utilization. Furthermore, results suggest a need for continued investigation of the role of family support in bridging the rural-urban divide in the health of older Thais.     

The health system of Argentina

This paper describes the health system of Argentina.This system has three sectors: public, social security and private.The public sector includes the national and provincial ministries as well as the network of public hospitals and primary health care units which provide care to the poor and uninsured population. This sector is financed with taxes and payments made by social security beneficiaries that use public health care facilities. The social security sector or Obras Sociales (OS) covers all workers of the formal economy and their families. Most OS operate through contracts with private providers and are financed with payroll contributions of employers and employees. Finally, the private sector includes all those private providers offering services to individuals, OS beneficiaries and all those with private health insurance.This sector also includes private insurance agencies called Prepaid Medicine Enterprises, financed mostly through premiums paid by families and/or employers.This paper also discusses some of the recent innovations implemented in Argentina, including the program Remediar.     

Perceptions and acceptability of mHealth interventions for improving patient care at a community-based HIV/AIDS clinic in Uganda: A mixed methods study

Mobile technologies for health (mHealth) represents a growing array of tools being applied in diverse health care settings. mHealth interventions for improving HIV/AIDS care is a promising strategy, but its evidence base is limited. We conducted a formative research evaluation to inform the development of novel mHealth HIV/AIDS care interventions to be used by community health workers (CHWs) in Kampala, Uganda. A mixed methods formative research approach was utilized. Qualitative methods included 20 in-depth interviews (IDIs) and six focus groups with CHWs, clinic staff, and patients. Thematic analysis was performed and selected quotations used to illustrate themes. Quantitative methods consisted of a survey administered to CHWs and clinic staff, using categorical and Likert scale questions regarding current mobile phone and internet access and perceptions on the potential use of smartphones by CHWs. Qualitative results included themes on significant current care challenges, multiple perceived mHealth benefits, and general intervention acceptability. Key mHealth features desired included tools to verify CHWs’ task completions, clinical decision support tools, and simple access to voice calling. Inhibiting factors identified included concerns about CHWs’ job security and unrealistic expectations of mHealth capabilities. Quantitative results from 27 staff participants found that 26 (96%) did not have internet access at home, yet only 2 (7.4%) did not own a mobile phone. Likert scale survey responses (1–5, 1 = Strongly Disagree, 5 = Strongly Agree) indicated general agreement that smartphones would improve efficiency (Mean = 4.35) and patient care (4.31) but might be harmful to patient confidentiality (3.88) and training was needed (4.63). Qualitative and quantitative results were generally consistent, and, overall, there was enthusiasm for mHealth technology. However, a number of potential inhibiting factors were also discovered. Findings from this study may help guide future design and implementation of mHealth interventions in this setting, optimizing their chances for success.     

INNOVATIVE SERVICE DELIVERY MODELS: LESSONS LEARNED IN PROVIDING CARE FOR OLDER PEOPLE AND PEOPLE WITH DISABILITIES

An evaluation is reported of six projects funded under the HACC (Home and Community Care) Program from Commonwealth Unmatched Monies. Each project provided an innovative service delivery model and two of the key purposes of the evaluation were to determine whether or not these models had been effective in meeting individual needs and to determine the factors most critical to supporting people at home. The evaluation found that the projects had been effective from both a service and a cost perspective and identified as the key factors a sense of security based on a belief in one's ability to manage care in the home setting, access to available services, flexibility in the provision of services and supports, effective case management and the presence of a caregiver. An analysis of costs was also undertaken and the projects were found to be cost-effective and considerably less expensive than equivalent care in a residential setting.     

Junior-headed households as a possible strategy for coping with the growing orphan crisis in northern Namibia

This paper reports research concerning junior-headed households among Oshiwambo speakers in north-central Namibia. Based on field interviews with randomly sampled junior heads of households and selected key informants, we outline some features common to the junior-headed households and the ways in which they attempt to manage their lives. The concepts of child- and junior-headed households are also clarified. We argue that due to a significant increase in the number of orphans in Namibia, the ability of extended families to absorb and care for orphaned children is beginning to fail. Although child-headed households are still rare in Namibia, junior-headed households — those led by young persons aged 18 years or more and who are unmarried and have not established a household of their own — appear to be more common. The paper poses the question, do junior-headed households represent a coping strategy in a situation where the upper limits of the ability of extended families to absorb and provide care for orphans has been reached? The ability of junior heads of households to run their households and care for younger children is limited by lack of experience, unemployment, and poverty. The primary function of these juniors appears to be maintaining order and providing basic security against abuse and the grabbing of property. By and large, such households are dependent on handouts from neighbours, relatives and the church, for food, clothing and financial support. We propose that efforts be made to secure access to education for junior heads of households, and to develop ways of improving their knowledge and skills regarding both household management and income-generating activities.     

Treating the right patient at the right time: access to heart failure care

Heart failure affects over 500,000 Canadians, and 50,000 new patients are diagnosed each year. The mortality remains staggering, with a five-year age-adjusted rate of 45%. Disease management programs for heart failure patients have been associated with improved outcomes, the use of evidence-based therapies, improved quality of care, and reduced costs, mortality and hospitalizations. Currently, national benchmarks and targets for access to care for cardiovascular procedures or office consultations do not exist. The present paper summarizes the currently available data, particularly focusing on the risk of adverse events as a function of waiting time, as well as on the identification of gaps in existing data on heart failure. Using best evidence and expert consensus, the present article also focuses on timely access to care for acute and chronic heart failure, including timely access to heart failure disease management programs and physician care (heart failure specialists, cardiologists, internists and general practitioners).     

Food Security in the Context of HIV: Towards Harmonized Definitions and Indicators

Integration of HIV and food security services is imperative to improving the health and well-being of people living with HIV. However, consensus does not exist on definitions and measures of food security to guide service delivery and evaluation in the context of HIV. This paper reviews definitions and indicators of food security used by key agencies; outlines their relevance in the context of HIV; highlights opportunities for harmonized monitoring and evaluation indicators; and discusses promising developments in data collection and management. In addition to the commonly used dimensions of food availability, access, utilization and stability, we identify three components of food security—food sufficiency, dietary quality, and food safety—that are useful for understanding and measuring food security needs of HIV-affected and other vulnerable people. Harmonization across agencies of food security indicators in the context of HIV offers opportunities to improve measurement and tracking, strengthen coordination, and inform evidence-based programming.     

Referral to hospital in Nepal: 4 years' experience in one rural district

Formal referral systems have been proposed as a strategy to improve access to secondary care, yet their implementation can be problematic. This paper describes data from referrals in one rural district in Nepal over a 4-year period. Whilst the characteristics of those patients attending hospital after referral were similar to those described in other developing countries, the rate (1.0/1000 population/year) is much lower, especially when compared to estimated need. Geographical and other barriers to access to secondary care in rural Nepal are discussed.     

Role of Health Information Technologies in the Patient-Centered Medical Home

A national effort to reform primary care, known as the Patient-Centered Medical Home (PCMH), requires fulfillment of six standards determined by the National Committee for Quality Assurance to (1) enhance access and continuity, (2) identify and manage patient populations, (3) plan and manage care, (4) provide self-care and community support, (5) track and coordinate care, and (6) measure and improve performance. Information technologies play a vital role in the support of most, if not all, of these standards. However, given the newness of the PCMH, little is known on how health information technologies (HITs) have been employed to accomplish these objectives. This article will review the role of HITs, including electronic health records, web-based patient portals, telemedicine, and patient registries, with a focus on diabetes care, and how these technologies have been engaged in the establishment of the PCMH. In addition, we will discuss the benefits and potential risks and barriers to employing these technologies, including privacy and security concerns, as well as describe next steps for future work in this important area.     

Does access to health care impact survival time after diagnosis of AIDS?

Lack of access to health care is often blamed for poor health outcomes, but this effect is not supported by existing HIV/AIDS literature. The authors examined the association between access to care and survival time after progression to AIDS, using survival analysis methods. This study combined data from two CDC sponsored studies of HIV-infected persons, a cross-sectional interview study and a longitudinal medical record review study. Study subjects included 752 persons who progressed to AIDS before December 31, 1999, and were patients at either of two major HIV care facilities in Detroit, MIchigan. Separate statistical models were used to test associations between survival time after meeting the criteria for AIDS and two indicators of access to health care: (1) perceived access to health care and (2) health care utilization patterns. Perceived access was not associated with survival time after AIDS, but patterns of health care utilization were significantly associated with survival time after AIDS (HR = 2.04, p < 0.001). Individuals who received a greater proportion of their care in the ER had a worse survival prognosis than those who received more of their health care in an outpatient clinic setting. It is crucial that we provide HIV-infected populations with tools that enable them to access a regular source of health care.     

Causes of hospitalization and perceived access to care among persons newly diagnosed with HIV infection: implications for HIV testing programs

There has been little research on the causes of hospitalization when patients are first diagnosed with HIV in the hospital. Reduced access to care could partially explain inpatient diagnosis. We sought to determine if the patients diagnosed as inpatients are hospitalized due to a HIV-related cause versus some other causes, to compare access to care of patients diagnosed with HIV in hospital and outpatient settings, and to determine factors associated with access to care. Participants were newly diagnosed with HIV and recruited between January 2006 and August 2007. The reason for hospitalization was classified as HIV-related, other infectious cause, noninfectious cause, or miscellaneous cause. Access to care was self-reported using a six-item scale and scores were compared with the t test. Multivariate linear regression determined factors associated with improved access to care. Of 185 participants in the study, 78 were diagnosed in hospital and 107 in outpatient settings. Thirty-two percent of participants were female, 90% were racial/ethnic minority, 45% had no high school diploma, and 85% were uninsured. HIV-related conditions accounted for 60% of admissions, followed by non-infectious causes (20%) and other infectious causes (17%). Inpatients did not report less access to care than patients diagnosed while outpatients. Multivariate analysis demonstrated improvement in access to care with better health insurance (p = 0.01) and greater education (p = 0.08). HIV-related preventable conditions account for many hospitalizations when patients are first diagnosed with HIV. While socioeconomic factors are associated with perceived access to care, persons diagnosed in the inpatient setting do not report lower perceived access to care than persons diagnosed as outpatients, suggesting other barriers to earlier diagnosis.
