Narrowing the health gap between a deprived and an endowed community

A 15 month campaign by a primary health care team in Stockton on Tees raised the uptake of preventive care of its patients in a severely deprived area to a level generally exceeding that of a more endowed neighbouring community. This was achieved by opportunistic attention after unrelated consultations, writing twice to each household with a list of its outstanding items necessary for preventive care, using health visitors to encourage attendance, and occasionally undertaking preventive care in patients'' homes. Extra clerical staff were needed to implement the new recording and monitoring procedures introduced.With rigorous monitoring and organisation general practitioners may improve the uptake of preventive health care by their more deprived patients.     

Vaccination campaigns in postsocialist Ukraine: health care providers navigating uncertainty

Vaccination anxieties grew into a public health issue during the 2008 failed measles and rubella immunization campaign in Ukraine. Here I explore how health care providers bend official immunization policies as they navigate media scares about vaccines, parents' anxieties, public health officials' insistence on the need for vaccination, and their own sense of expertise and authority. New hierarchies are currently being renegotiated, and I follow health care providers as they attempt to parcel out their new position in the Ukrainian society and beyond. Public health control is reframed in a postsocialist context as a condition of acceptance into the European community as a sanitary democracy, and a contestation point between citizens and state. I untangle how relationships between citizens and states shape the construction of medical risk.     

Costs of Illness Due to Cholera, Costs of Immunization and Cost-Effectiveness of an Oral Cholera Mass Vaccination Campaign in Zanzibar

Background

The World Health Organization (WHO) recommends oral cholera vaccines (OCVs) as a supplementary tool to conventional prevention of cholera. Dukoral, a killed whole-cell two-dose OCV, was used in a mass vaccination campaign in 2009 in Zanzibar. Public and private costs of illness (COI) due to endemic cholera and costs of the mass vaccination campaign were estimated to assess the cost-effectiveness of OCV for this particular campaign from both the health care provider and the societal perspective.

Methodology/Principal Findings

Public and private COI were obtained from interviews with local experts, with patients from three outbreaks and from reports and record review. Cost data for the vaccination campaign were collected based on actual expenditure and planned budget data. A static cohort of 50,000 individuals was examined, including herd protection. Primary outcome measures were incremental cost-effectiveness ratios (ICER) per death, per case and per disability-adjusted life-year (DALY) averted. One-way sensitivity and threshold analyses were conducted. The ICER was evaluated with regard to WHO criteria for cost-effectiveness. Base-case ICERs were USD 750,000 per death averted, USD 6,000 per case averted and USD 30,000 per DALY averted, without differences between the health care provider and the societal perspective. Threshold analyses using Shanchol and assuming high incidence and case-fatality rate indicated that the purchase price per course would have to be as low as USD 1.2 to render the mass vaccination campaign cost-effective from a health care provider perspective (societal perspective: USD 1.3).

Conclusions/Significance

Based on empirical and site-specific cost and effectiveness data from Zanzibar, the 2009 mass vaccination campaign was cost-ineffective mainly due to the relatively high OCV purchase price and a relatively low incidence. However, mass vaccination campaigns in Zanzibar to control endemic cholera may meet criteria for cost-effectiveness under certain circumstances, especially in high-incidence areas and at OCV prices below USD 1.3.     

Integrated HIV testing, malaria, and diarrhea prevention campaign in Kenya: modeled health impact and cost-effectiveness

Background

Efficiently delivered interventions to reduce HIV, malaria, and diarrhea are essential to accelerating global health efforts. A 2008 community integrated prevention campaign in Western Province, Kenya, reached 47,000 individuals over 7 days, providing HIV testing and counseling, water filters, insecticide-treated bed nets, condoms, and for HIV-infected individuals cotrimoxazole prophylaxis and referral for ongoing care. We modeled the potential cost-effectiveness of a scaled-up integrated prevention campaign.

Methods

We estimated averted deaths and disability-adjusted life years (DALYs) based on published data on baseline mortality and morbidity and on the protective effect of interventions, including antiretroviral therapy. We incorporate a previously estimated scaled-up campaign cost. We used published costs of medical care to estimate savings from averted illness (for all three diseases) and the added costs of initiating treatment earlier in the course of HIV disease.

Results

Per 1000 participants, projected reductions in cases of diarrhea, malaria, and HIV infection avert an estimated 16.3 deaths, 359 DALYs and $85,113 in medical care costs. Earlier care for HIV-infected persons adds an estimated 82 DALYs averted (to a total of 442), at a cost of $37,097 (reducing total averted costs to $48,015). Accounting for the estimated campaign cost of $32,000, the campaign saves an estimated $16,015 per 1000 participants. In multivariate sensitivity analyses, 83% of simulations result in net savings, and 93% in a cost per DALY averted of less than $20.

Discussion

A mass, rapidly implemented campaign for HIV testing, safe water, and malaria control appears economically attractive.     

Interactions between Global Health Initiatives and Country Health Systems: The Case of a Neglected Tropical Diseases Control Program in Mali

Background

Recently, a number of Global Health Initiatives (GHI) have been created to address single disease issues in low-income countries, such as poliomyelitis, trachoma, neonatal tetanus, etc.. Empirical evidence on the effects of such GHIs on local health systems remains scarce. This paper explores positive and negative effects of the Integrated Neglected Tropical Disease (NTD) Control Initiative, consisting in mass preventive chemotherapy for five targeted NTDs, on Mali''s health system where it was first implemented in 2007.

Methods and Findings

Campaign processes and interactions with the health system were assessed through participant observation in two rural districts (8 health centres each). Information was complemented by interviews with key informants, website search and literature review. Preliminary results were validated during feedback sessions with Malian authorities from national, regional and district levels. We present positive and negative effects of the NTD campaign on the health system using the WHO framework of analysis based on six interrelated elements: health service delivery, health workforce, health information system, drug procurement system, financing and governance. At point of delivery, campaign-related workload severely interfered with routine care delivery which was cut down or totally interrupted during the campaign, as nurses were absent from their health centre for campaign-related activities. Only 2 of the 16 health centres, characterized by a qualified, stable and motivated workforce, were able to keep routine services running and to use the campaign as an opportunity for quality improvement. Increased workload was compensated by allowances, which significantly improved staff income, but also contributed to divert attention away from core routine activities. While the campaign increased the availability of NTD drugs at country level, parallel systems for drug supply and evaluation requested extra efforts burdening local health systems. The campaign budget barely financed institutional strengthening. Finally, though the initiative rested at least partially on national structures, pressures to absorb donated drugs and reach short-term coverage results contributed to distract energies away from other priorities, including overall health systems strengthening.

Conclusions

Our study indicates that positive synergies between disease specific interventions and nontargeted health services are more likely to occur in robust health services and systems. Disease-specific interventions implemented as parallel activities in fragile health services may further weaken their responsiveness to community needs, especially when several GHIs operate simultaneously. Health system strengthening will not result from the sum of selective global interventions but requires a comprehensive approach.     

Demands on surgical inpatient services after mass mammographic screening.

The changes in the demand for surgical inpatient care created by mammographic screening for breast cancer were analysed by comparing two counties, one with and one without a mass screening campaign. A comprehensive computerised register of inpatient care in the region was used. The results indicate that population based screening offered to women above 40 years and repeated every two to three years will increase the number of operations required for breast cancer and inpatient days by at least 150% during the initial screening round. During the second round the figures tend to return to previous levels. Of decisive importance for the demands on health service resources are the specificity of screening, the duration of the first screening round, and the age groups included.     

Costs of mass drug administration for scabies in Fiji

In 2019, the Murdoch Children’s Research Institute in partnership with the Fiji Ministry of Health and Medical Services carried out an integrated mass drug administration (MDA) for the treatment of scabies and lymphatic filariasis in the Northern Division of Fiji (population estimate 131,914). We conducted a retrospective micro-costing exercise focused on the cost of scabies control in order to inform budgeting and policy decision making in an endemic setting. We collected detailed information on financial and economic costs incurred by both parties during the course of the MDA campaign (April 2018 to July 2019). We also conducted interviews with personnel involved in the financial administration of the MDA campaign. The economic cost of delivering two doses of ivermectin was US$4.88 per person. The cost of donated drugs accounted for 36.3% of total MDA costs. In this first large-scale MDA for the public health control of scabies, the estimated cost of delivering MDA per person for scabies was considerably more expensive than the costs reported for other neglected tropical diseases. The important cost drivers included the remuneration of health care workers who were extensively involved in the campaign, coverage of hard-to-reach, mainly rural populations and the two-dose regimen of ivermectin. These results highlight the importance of these cost determinants and can be used to plan current and future MDA programs.     

Hepatitis B in China： from Guideline to Practice

Chronic hepatitis B infection is a very important health problem in China, which is carrying an enormous economic and social burdens. The major routs of chronic hepatitis B infection in China are mother-infant vertical transmission and early childhood horizontal transmission. After more than 10 years implementation of universal vaccination against hepatitis B in newborns and safety injection in health care settings, the prevalence of HBsAg in general population has decreased from 9.75% to around 7%. In China, patients with hepatitis are cared by either hepatologists or physicians of infectious diseases. The Chinese Society of Hepatology, and Chinese Society of Infectious Diseases jointly issued an evidence-based guideline on the prevention and treatment of chronic hepatitis B in 2005. This guideline concisely describes the virology, epidemiology, natural history and prevention, as well as diagnosis and management of chronic hepatitis B. It also highlights the importance of active viral replication in disease progression in chronic HBV infection and explicitly states the necessity of antiviral therapy in patient care. The cornerstone of anti-hepatitis B therapy is optimal use of interferons or nucleos(t)ide analogs in those patients with active viral replication and elevated serum transaminase levels. Through an independent continue medical educational agency, a panel of selected speakers were trained to give well-formatted talks on the key points of the guideline in over 60 major cities across China. This educational campaign among health care providers has greatly improved the awareness and the stand of care for antiviral therapy.     

Professional unity to be a key focus for CMA in 1996

The need for professional unity in the face of growing government pressure is to be a key focus of the CMA''s 1996 activities, the Board of Directors decided at its December meeting. This will become clear as its future of health care campaign develops, with twin components of patient and physician advocacy. The board also learned that details about a major antismoking project have been finalized and of potential expansion within the Department of Publications.     

Women and AIDS: the ethics of exaggerated harm

This article examines the way in which some biomedical ethicists have constructed sexually transmitted AIDS as a significant threat to women's health. We demonstrate that the familiar claim that'women are the fastest growing group'— whether of HIV-infected or of AIDS patients — is misleading because it obscures the distinction between proportional rate of growth and absolute increase. Feminist ethicists have suggested that misogyny of a male dominated health care system has led to underreporting of women AIDS cases in order to support these feminists'claim of AIDS being a real threat to women's health. Given the apparent rarity of tertiary transmissions of AIDS, the assertion that most or even many women are at significant risk for AIDS seem wrong. Particularly disturbing in this campaign is the fact that the theme of'risky sex'has been extended all the way to lesbians, even though their risk to acquire AIDS sexually is non-existent to minuscule. We argue that actual harm is done to women by this exaggeration of their risk of contracting AIDS sexually. The scare has led to misappropriations of scarce health care funds. AIDS disproportionately affects women who inject drugs, and who suffer other diseases, poverty and malnutrition. It would have been better to concentrate health care efforts in this area instead of'educating'women not at risk for AIDS how to prevent the acquisition of this disease. Unjustifiable AIDS anxiety has been created in women and has resulted in millions of unnecessary HIV-tests, and many broken relationships. This anxiety has inevitably reduced the pleasure of having sex for many women. We reject the kind of'victim ideology'that lies at the heart of this strategy which has, unfortunately, been supported by a number of influential feminist ethicists.

Beneficial effects on employment and preventive health care: the concept and results of counselling processes from a German project

Since December 1998 a project of working time counselling named "Design of Modern Working Times" is supported by the federal state of North Rhine-Westphalia in Germany and the European Union; AWiS-consult is entrusted to carry out this project. The service offered to all companies, institutions, work committees, and employees interested covers information, assessment of existing working time schedules, development of alternative or new working time schedules, and accompanying implementation processes. Up to June 2001 nearly 300 inquiries were worked on, most of them from industry, service companies, and from the field of care and hospitals. Working time design in this project aims not only at work safety and health care but also at beneficial effects on employment. In a special campaign from May 2000 to May 2001, 61 companies were supported by AWiS-consult, with the result of more than 400 new employees and 16 companies with employment secured, so the combination of preventive health care and beneficial effects on employment by working time design can be assessed as successful.     

Reduction in Malaria Incidence following Indoor Residual Spraying with Actellic 300 CS in a Setting with Pyrethroid Resistance: Mutasa District,Zimbabwe

Background

More than half of malaria cases in Zimbabwe are concentrated in Manicaland Province, where seasonal malaria epidemics occur despite intensified control strategies. Recently, high levels of pyrethroid and carbamate resistance were detected in Anopheles funestus, the major malaria vector in eastern Zimbabwe. In response, a single round of indoor residual spraying (IRS) using pirimiphos-methyl (an organophosphate) was implemented in four high burden districts of Manicaland Province from November 1, 2014 to December 19, 2014. The objective of this study was to evaluate the effect of this programmatic switch in insecticides on malaria morbidity reported from health care facilities in Mutasa District, one of the worst affected districts in Manicaland Province.

Methods

The number of weekly malaria cases for each health facility 24 months prior to the 2014 IRS campaign and in the subsequent high transmission season were obtained from passive case surveillance. Environmental variables were extracted from remote-sensing data sources and linked to each health care facility. Negative binomial regression was used to model the weekly number of malaria cases, adjusted for seasonality and environmental variables.

Results

From December 2012 to May 2015, 124,206 malaria cases were reported from 42 health care facilities in Mutasa District. Based on a higher burden of malaria, 20 out of 31 municipal wards were sprayed in the district. Overall, 87.3% of target structures were sprayed and 92.1% of the target population protected. During the 6 months after the 2014 IRS campaign, a period when transmission would have otherwise peaked, the incidence of malaria was 38% lower than the preceding 24 months at health facilities in the sprayed wards.

Conclusions

Pirimiphos-methyl had a measurable impact on malaria incidence and is an effective insecticide for the control of An. funestus in eastern Zimbabwe.     

Where is the silver lining? Anxious doctors ask.

When Nova Scotia elected a Liberal government in September 1993, a wave of optimism washed over the province''s medical community. One of their own, Dr. John Savage, was now premier, and another, Dr. Ron Stewart, was minister of health. However, anticipation soon turned to anger as Stewart took aim at physician fees and hospital costs to help reduce the province''s health care budget by $62 million. Last November, relations between him and the Medical Society of Nova Scotia (MSNS) hit bottom. In an uncharacteristically political move, the society launched an ad campaign featuring slogans such as "Death by 1000 cuts" and "Uncle Sam want me. Ron Stewart doesn''t." Four months later, the health department and the MSNS called a truce, with an agreement that many physicians consider a positive step. Today the province and its doctors are speaking again, and the medical society is working hard to help define physicians'' roles in a new, regionalized health care system. But has the mood of doctors really improved? Last spring, CMAJ interviewed a cross section of Nova Scotia physicians to find out.     

The social network around influenza vaccination in health care workers: a cross-sectional study

Background

Influenza vaccination coverage remains low among health care workers (HCWs) in many health facilities. This study describes the social network defined by HCWs’ conversations around an influenza vaccination campaign in order to describe the role played by vaccination behavior and other HCW characteristics in the configuration of the links among subjects.

Methods

This study used cross-sectional data from 235 HCWs interviewed after the 2010/2011 influenza vaccination campaign at the Hospital Clinic of Barcelona (HCB), Spain. The study asked: “Who did you talk to or share some activity with respect to the seasonal vaccination campaign?” Variables studied included sociodemographic characteristics and reported conversations among HCWs during the influenza campaign. Exponential random graph models (ERGM) were used to assess the role of shared characteristics (homophily) and individual characteristics in the social network around the influenza vaccination campaign.

Results

Links were more likely between HCWs who shared the same professional category (OR 3.13, 95% CI?=?2.61–3.75), sex (OR 1.34, 95% CI?=?1.09–1.62), age (OR 0.7, 95% CI?=?0.63–0.78 per decade of difference), and department (OR 11.35, 95% CI?=?8.17–15.64), but not between HCWs who shared the same vaccination behavior (OR 1.02, 95% CI?=?0.86–1.22). Older (OR 1.26, 95% CI?=?1.14–1.39 per extra decade of HCW) and vaccinated (OR 1.32, 95% CI?=?1.09–1.62) HCWs were more likely to be named.

Conclusions

This study finds that there is no homophily by vaccination status in whom HCWs speak to or interact with about a workplace vaccination promotion campaign. This result highlights the relevance of social network analysis in the planning of health promotion interventions.

     

Can general practitioners influence exercise habits? Controlled trial.

A health promotion campaign in the community organised by the general practitioner was evaluated by the use of a questionnaire before and after the campaign, both in the village where the campaign was based and in a control village. There was a general increase in the amount of exercise that people in both villages took. The results showed that having received a questionnaire, and been subject to the campaign, more people took exercise regularly.     

Policy for prevention of Asian rickets in Britain: a preliminary assessment of the Glasgow rickets campaign.

Evidence of continuing hospital admissions of patients with Asian rickets and osteomalacia led to a further attempt to provide more effective preventive measures for the Glasgow Asian community. Dose-response studies showed that the equivalent of 10 microgram of vitamin D daily would provide effective prophylaxis, and a general practice survey showed that self-administered vitamin D supplements would reduce the prevalence and severity of Asian rickets. A multidisciplinary working group devised a preventive campaign based on the free issue of vitamin D supplements on demand to children who required them. Supported by a health education programme for community health personnel and the Asian community, the first 16 months of the campaign produced an eight-fold rise in the issue of supplements to older Asian children and a 33% increase in their issue to infants of all ethnic groups. Because more children are receiving vitamin D supplementation the campaign seems likely to reduce the prevalence of Asian rickets in Glasgow.     

Trends in the association of obesity and self-reported overall health in 30 years of the Integrated Health Interview Series

This research examines trends in the relationship between obesity based on self-report height and weight and self-perceived health over a 30-year period. Importantly, this period included the articulation of comprehensive public health campaigns on excess weight and thus provides opportunities for assessment of the efficacy of the campaign, as well as the broader psycho-social impact of excess weight. Using novel data from the Integrated Health Interview Series, odds ratios for the association between obesity and self-perceived health were estimated for repeated cross-sectional samples that are nationally representative of noninstitutionalized American adults aged 18-85 and older spanning 1976-2006. Our findings show that (i) there are weak associations between obesity and self-perceived poor health; (ii) these associations are particularly small among men, often to the point of being nonexistent; and (iii) weak relationships for both men and women have remained virtually unchanged over the past 30 years. Several reasons why the public health campaign around excess weight has had limited traction are discussed including the collective problem of excess weight in America and how this undermines current approaches in public health efforts addressing excess weight.     

Hazards Associated with the Consumption of Sea Turtle Meat and Eggs: A Review for Health Care Workers and the General Public

Sea turtle products (e.g., meat, adipose tissue, organs, blood, eggs) are common food items for many communities worldwide, despite national regulations in some countries prohibiting such consumption. However, there may be hazards associated with this consumption due to the presence of bacteria, parasites, biotoxins, and environmental contaminants. Reported health effects of consuming sea turtles infected with zoonotic pathogens include diarrhea, vomiting, and extreme dehydration, which occasionally have resulted in hospitalization and death. Levels of heavy metals and organochlorine compounds measured in sea turtle edible tissues exceed international food safety standards and could result in toxic effects including neurotoxicity, kidney disease, liver cancer, and developmental effects in fetuses and children. The health data presented in this review provide information to health care providers and the public concerning the potential hazards associated with sea turtle consumption. Based on past mortality statistics from turtle poisonings, nursing mothers and children should be particularly discouraged from consuming all sea turtle products. We recommend that individuals choose seafood items lower in the food chain that may have a lower contaminant load. Dissemination of this information via a public health campaign may simultaneously improve public health and enhance sea turtle conservation by reducing human consumption of these threatened and endangered species.
