The utilization of mobile devices for telemedicine services in a South African public healthcare system

The purpose of this study is to develop an understanding in the use of mobile devices in administering telemedicine services within the public health care sector of South Africa. An online questionnaire was developed and distributed amongst medical officers, specialists, students and medical staff of one of the health districts of South Africa. This paper describes the design of the questionnaire as well as the most significant outcomes. Results are presented in terms of reasons why healthcare workers use mobile devices, as well as perceptions in terms of transmission security and quality of transmitted information.

Who knows more about immunization?: Survey of public health nurses and physicians

OBJECTIVE

To report the findings of a knowledge survey of nurse and physician immunization providers.

DESIGN

Cross-sectional postal survey assessing demographic characteristics and vaccine knowledge.

SETTING

British Columbia (BC).

PARTICIPANTS

Nurse and physician immunization providers in BC.

MAIN OUTCOME MEASURES

Knowledge of vaccine-preventable diseases, vaccines in general, and vaccine administration and handling practices.

RESULTS

Survey responses were received from 256 nurses and 292 physicians (response rates of 48.6% and 18.3%, respectively). Most nurses (98.4%) reported receiving immunization training outside of the academic setting compared with 55.6% of physicians. Overall, nurse immunizers scored significantly higher than physician immunizers on all 3 domains of immunization knowledge (83.7% vs 72.8%, respectively; P < .001). Physicians scored highest on the vaccine-preventable disease domain and least well on the general vaccine domain. Nurses with more experience as health care providers scored higher. Physicians scored higher if they were female, served patient populations predominantly younger than 5 years, or received immunization training outside of academic settings.

CONCLUSION

In BC, nurse immunizers appear to have higher overall immunization knowledge than physicians and are more likely to receive immunization training when in practice. Physician immunizers might benefit most from further training on vaccines and vaccine administration and handling.

Population-based versus practice-based recall for childhood immunizations: a randomized controlled comparative effectiveness trial

OBJECTIVES

We compared the effectiveness and cost-effectiveness of population-based recall (Pop-recall) versus practice-based recall (PCP-recall) at increasing immunizations among preschool children.

METHODS

This cluster-randomized trial involved children aged 19 to 35 months needing immunizations in 8 rural and 6 urban Colorado counties. In Pop-recall counties, recall was conducted centrally using the Colorado Immunization Information System (CIIS). In PCP-recall counties, practices were invited to attend webinar training using CIIS and offered financial support for mailings. The percentage of up-to-date (UTD) and vaccine documentation were compared 6 months after recall. A mixed-effects model assessed the association between intervention and whether a child became UTD.

RESULTS

Ten of 195 practices (5%) implemented recall in PCP-recall counties. Among children needing immunizations, 18.7% became UTD in Pop-recall versus 12.8% in PCP-recall counties (P < .001); 31.8% had documented receipt of 1 or more vaccines in Pop-recall versus 22.6% in PCP-recall counties (P < .001). Relative risk estimates from multivariable modeling were 1.23 (95% confidence interval [CI] = 1.10, 1.37) for becoming UTD and 1.26 (95% CI = 1.15, 1.38) for receipt of any vaccine. Costs for Pop-recall versus PCP-recall were $215 versus $1981 per practice and $17 versus $62 per child brought UTD.

CONCLUSIONS

Population-based recall conducted centrally was more effective and cost-effective at increasing immunization rates in preschool children.

[Fertility treatment options for discordant couples living with HIV]

BACKGROUND

Serodiscordant couples live with the risk of HIV infection of the negative partner when attempting to become pregnant. Using density gradient centrifugation (DGC), spermatozoa can be separated from other seminal compartments. Isolated spermatozoa do not contain detectable HIV RNA. DGC followed by artificial insemination may significantly reduce the risk of infection. The Hadassah AIDS Center (HAC) has recently initiated a fertility center for serodiscordant couples.

METHODS

Our patient population includes serodiscordant couples in which the male is HIV positive. The male semen is washed using the DGC procedure. Washed semen is tested for HIV by standard PCR methods. Intrauterine insemination (IUI) is attempted using the washed semen.

RESULTS

A total of 55 couples have registered for this procedure. This includes 16 men who have sex with men, 7 who have hemophilia and 8 couples of Ethiopian origin. The average female age is 33 years. Seven (12%) men had inadequate sperm counts and were referred for IVF. Overall, 34 semen samples were tested for HIV. Only one was found to be positive. During the procedure, 22 couples underwent at least one IUI attempt and 16 (72%) females became pregnant, 3 of them after the first IUI attempt. All women tested for HIV after IUI were found to be negative.

CONCLUSIONS

The pregnancy success rate during the first year of operation was 72%, similar to that reported by other centers in Europe. There were no seroconversions of the female partner. Serodiscordant couples living with HIV in Israel today may consider starting a family, while significantly reducing the risk of infecting the negative female partner.

Big bad data: law, public health, and biomedical databases

The accelerating adoption of electronic health record (EHR) systems will have far-reaching implications for public health research and surveillance, which in turn could lead to changes in public policy, statutes, and regulations. The public health benefits of EHR use can be significant. However, researchers and analysts who rely on EHR data must proceed with caution and understand the potential limitations of EHRs. Because of clinicians' workloads, poor user-interface design, and other factors, EHR data can be erroneous, miscoded, fragmented, and incomplete. In addition, public health findings can be tainted by the problems of selection bias, confounding bias, and measurement bias. These flaws may become all the more troubling and important in an era of electronic "big data," in which a massive amount of information is processed automatically, without human checks. Thus, we conclude the paper by outlining several regulatory and other interventions to address data analysis difficulties that could result in invalid conclusions and unsound public health policies.

Adherence by Dutch public health nurses to the national guidelines for tuberculosis contact investigation

Objectives

To assess whether public health nurses adhered to Dutch guidelines for tuberculosis contact investigations and to explore which factors influenced the process of identifying contacts, prioritizing contacts for testing and scaling up a contact investigation.

Methods

A multiple-case study (2010–2012) compared the contact investigation guidelines as recommended with their use in practice. We interviewed twice 14 public health nurses of seven Public Health Services while they conducted a contact investigation.

Results

We found more individuals to be identified as contacts than recommended, owing to a desire to gain insight into the infectiousness of the index case and prevent anxiety among potential contacts. Because some public health nurses did not believe the recommendations for prioritizing contacts fully encompassed daily practice, they preferred their own regular routine. In scaling up a contact investigation, they hardly applied the stone-in-the-pond principle. They neither regularly compared the infection prevalence in the contact investigation with the background prevalence in the community, especially not in immigrant populations. Nonadherence was related to ambiguity of the recommendations and a tendency to act from an individual health-care position rather than a population health perspective.

Conclusions

The adherence to the contact investigation guidelines was limited, restraining the effectiveness, efficiency and uniformity of tuberculosis control. Adherence could be optimized by specifying guideline recommendations, actively involving the TB workforce, and training public health nurses.

Harmonizing databases? Developing a quasi-experimental design to evaluate a public mental health re-entry program

Our study is the first-ever initiative to merge administrative databases in Massachusetts to evaluate an important public mental health program. It examines post-incarceration outcomes of adults with serious mental illness (SMI) enrolled in the Massachusetts Department of Mental Health (DMH) Forensic Transition Team (FTT) program. The program began in 1998 with the goal of transitioning offenders with SMI released from state and local correctional facilities utilizing a core set of transition activities. In this study we evaluate the program's effectiveness using merged administrative data from various state agencies for the years 2007-2011, comparing FTT clients to released prisoners who, despite having serious mental health disorders, did not meet the criterion for DMH services. By systematically describing our original study design and the barriers we encountered, this report will inform future efforts to evaluate public programs using merged administrative databases and electronic health records.

A multifaceted public health approach to statewide aviation safety

BACKGROUND

During the 1990s, Alaskan pilots had one of the most hazardous occupations in the US. In 2000, a multifaceted public health initiative was launched, focusing on Alaskan air taxi/commuter (AT) operations, including risk factor identification, improved weather information, and the formation of an industry-led safety organization.

METHODS

Effectiveness was assessed by comparing rates of crashes using Poisson regression, comparing trends in annual numbers of crashes, and assessing changes in the number and type of controlled flight into terrain (CFIT) events.

RESULTS

The greatest improvements were seen in Alaska fatal AT crashes with a 57% decrease in rates between time periods. While the number of AT crashes in the rest of the US steadily declined during 1990-2009, Alaska only showed significant declines after 2000. CFIT crashes declined but remained more deadly than other crashes.

CONCLUSIONS

This coordinated effort was successful in reducing crashes in the Alaskan AT industry.

Mapping of sexual health promotion in North West England, 2008

OBJECTIVE

To map sexual health promotion activity and resources across North West England.

STUDY DESIGN

Survey.

METHODS

A survey of all sexual health promotion activity commissioned by primary care trusts (PCTs) was carried out using a self-completion questionnaire for PCT sexual health commissioners in North West England.

RESULTS

Sixteen out of 24 PCTs responded. Some PCTs had difficulty in identifying the relevant commissioner. Most activity was focused on young people, especially around the National Chlamydia Screening Programme (NCSP) and teenage pregnancy, and on particular high-risk groups such as lesbian, gay and bisexual people, those living with human immunodeficiency virus and commercial sex workers. All PCTs commissioned education/training and a condom distribution service. Other common activities included outreach work, and producing and disseminating materials. Most services were confined to one PCT. Most PCTs were unable to identify the resources committed to sexual health promotion. The emergent themes in the analysis of service development ideas and comments were all linked to commissioning: commissioning and strategy; funding; needs assessment; service development and provision; contracting and monitoring; evaluation and evidence; and regional perspective.

CONCLUSIONS

A simple tool to map sexual health promotion activities commissioned by PCTs was developed. Many PCTs could not identify a commissioner for sexual health or the resources committed to sexual health promotion. Sexual health promotion activity focused on young people (linked to the NCSP and teenage pregnancy) and particular high-risk groups, with resultant gaps and a mismatch with the epidemiology. The most frequently commissioned activities were education/training and condom provision (despite the limited evidence base). A series of recommendations to PCTs, sexual health networks and providers are made.

Intimate partner violence at the scene: incident characteristics and implications for public health surveillance

Using data that, to our knowledge, have not been used before for this purpose, we examined 9,231 opposite-sex intimate partner violence (IPV) calls for law enforcement assistance recorded in the Compstat system of a large U.S. city. Although women were the predominant victims, injuries were documented more often for men. Only about 1% of incidents were considered a restraining order violation, although many orders were active in the city at the time. The data appeared to be of good quality and just a few changes in recording procedures would increase Compstat's usefulness for public health in U.S. cities.

Improving service delivery in a county health department WIC clinic: an application of statistical process control techniques

Local public health agencies are challenged to continually improve service delivery, yet they frequently operate with constrained resources. Quality improvement methods and techniques such as statistical process control are commonly used in other industries, and they have recently been proposed as a means of improving service delivery and performance in public health settings. We analyzed a quality improvement project undertaken at a local Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) clinic to reduce waiting times and improve client satisfaction with a walk-in nutrition education service. We used statistical process control techniques to evaluate initial process performance, implement an intervention, and assess process improvements. We found that implementation of these techniques significantly reduced waiting time and improved clients' satisfaction with the WIC service.

Malignant cancer mortality in Province of Taranto (Italy). Geographic analysis in an area of high environmental risk

BACKGROUND

A geographic analysis of the causes of death is an important tool for assessing the effectiveness of Public Health initiatives. The aim of this study is to analyse the causes of death between 2000 and 2004, to discover any excess mortality from cancer in Province of Taranto, an area at high environmental risk.

METHODS

Mortality data from cancer were selected from the Puglia Regional Nominative Causes of Death Registry. Crude and standardized rates and Standardized Mortality Ratios (SMR) were calculated for the five Provinces of the Puglia Region, their capital cities and in four concentric rings around the industrial area located in Province of Taranto.

RESULTS

. Even if the highest death rate for all tumours resulted in the Province of Lecce (24.9 x 10,000), in the cities of Lecce and Bari (29 x 10,000), the distribution of the SMRs in Province of Taranto showed an excess of mortality (+10%) in the ring next to industrial area. For lung cancer the highest rate was reported in city of Taranto (6 x 10,000) and the highest risk (+24%) in the ring next to industrial area. Moreover, in this area 9 (70%) of the 13 considered malignant tumours types presented an excess of mortality.

CONCLUSION

The results uphold the data reported in the published literature. It is fundamental to intensify research into other risk factors (exposure at work and aberrant lifestyles). Moreover, there is an increasing need for a Regional Cancer Register.

Small-area estimation and prioritizing communities for tobacco control efforts in Massachusetts

OBJECTIVES

We developed a method to evaluate geographic and temporal variations in community-level risk factors and prevalence estimates, and used that method to identify communities in Massachusetts that should be considered high priority communities for smoking interventions.

METHODS

We integrated individual-level data from the Behavioral Risk Factor Surveillance System from 1999 to 2005 with community-level data in Massachusetts. We used small-area estimation models to assess the associations of adults' smoking status with both individual- and community-level characteristics and to estimate community-specific smoking prevalence in 398 communities. We classified communities into 8 groups according to their prevalence estimates, the precision of the estimates, and temporal trends.

RESULTS

Community-level prevalence of current cigarette smoking among adults ranged from 5% to 36% in 2005 and declined in all but 16 (4%) communities between 1999 and 2005. However, less than 15% of the communities met the national prevalence goal of 12% or less. High smoking prevalence remained in communities with lower income, higher percentage of blue-collar workers, and higher density of tobacco outlets.

CONCLUSIONS

Prioritizing communities for intervention can be accomplished through the use of small-area estimation models. In Massachusetts, socioeconomically disadvantaged communities have high smoking prevalence rates and should be of high priority to those working to control tobacco use.

Strengthening health systems in poor countries: a code of conduct for nongovernmental organizations

The challenges facing efforts in Africa to increase access to antiretroviral HIV treatment underscore the urgent need to strengthen national health systems across the continent. However, donor aid to developing countries continues to be disproportionately channeled to international nongovernmental organizations (NGOs) rather than to ministries of health. The rapid proliferation of NGOs has provoked "brain drain" from the public sector by luring workers away with higher salaries, fragmentation of services, and increased management burdens for local authorities in many countries. Projects by NGOs sometimes can undermine the strengthening of public primary health care systems. We argue for a return to a public focus for donor aid, and for NGOs to adopt a code of conduct that establishes standards and best practices for NGO relationships with public sector health systems.

Improving traffic safety: conceptual considerations for successful action

INTRODUCTION

In the early stages of motorization, it did not take rigorous scientific research to achieve major improvements in traffic safety. Instead, early traffic-safety countermeasures were often based exclusively on common sense. Since then, scientific research has gradually increased in importance as the basis for developing successful interventions. This shift was not made by choice but mostly by necessity: many of the "easy" problems have already been addressed, and the remaining problems are generally too complex for an approach based solely on common sense. Fortunately, our understanding of the complexities involved in traffic safety has recently made major gains, and common sense can now be supplemented, to some degree, by valid technical analysis.

APPROACH

This article discusses major conceptual issues that should be considered in guiding the future development of effective, science-based traffic-safety countermeasures.

IMPACT ON INDUSTRY

After briefly discussing the conceptual issues, the article offers a list of implications for action.

Antimicrobial prescription patterns for common acute infections in some rural & urban health facilities of India

BACKGROUND & OBJECTIVES

Irrational use of antimicrobials is a key factor behind rapidly spreading antimicrobial resistance in microorganisms. This study was undertaken to determine the rate and pattern of antimicrobial prescribing in patients with uncomplicated acute respiratory infections, fever and diarrhoea attending a few rural and urban health settings.

METHODS

The study was done in primary and secondary health care facilities of public/government and private settings at four sites in India. Patients with fever, cough, diarrhoea or ear, nose or throat infections of < 7 days were included. Pregnant women, lactating mothers, infants, seriously ill patients and patients with bloody diarrhoea or purulent nasal or ear discharge were excluded.

RESULTS

Overall antimicrobial prescription rate was 69.4 per cent (95% CI 67.1, 71.7). Wide variation was observed (Thiruvananthapuram 47.6%, Lucknow 81.8%, Chennai 73.1% and Vellore 76.5%). Physicians practicing in rural and public/government settings prescribed antimicrobials more frequently than those in urban and private settings (83.8, 81.9, 68.3 and 68.2% respectively). Antimicrobials were more frequently prescribed for patients presenting with fever. Highest rate was noticed for children aged between 6 and 18 yr. Patients of the high-income group received antimicrobials more frequently (72.7%). In both public/ government and private settings, for patients who purchased medicines, the rate was higher (82.4 and 68.9% respectively), vs. those receiving free medicines (70.2 and 46.2% respectively). Two third of all antimicrobials prescribed were penicillins and co-trimoxazole, and > 40 per cent of prescriptions from private sector were quinolones and cephalosporins.

INTERPRETATION & CONCLUSIONS

Our findings showed that prescription of antimicrobials for acute respiratory infections and diarrhoea was extremely common and warrants interventional strategies.

Accreditation/Performance Assessment On-Site Reviews in Michigan, Missouri, North Carolina, and Washington

In 1988, the Committee for the Study of the Future of Public Health identified the core functions of assessment, policy development, and assurance as key roles of the public health governmental sector. Some states have developed accreditation or performance assessment programs to measure how state and/or local government carry out these functions. Several of these programs share a common "on-site review" component defined as a site-specific visit to assess, observe, interview, review, evaluate, and/or survey a local/state agency or program regarding its ability to meet a set of public health standards. This article describes the experience of four states-Michigan, Missouri, North Carolina, and Washington-in developing and conducting on-site reviews for accreditation or performance assessment.

Local Public Health Certification and Accreditation in Illinois

Funded by the Robert Wood Johnson Foundation through the Multi-State Learning Collaborative, the Illinois Accreditation Development Project is developing a proposal to reengineer the 15-year-old Illinois local health department certification process. The Project is addressing a variety of political, technical, and resource issues in its attempt to develop a new approach to a mature program that will incorporate more meaningful performance and capacity measures for all local public health practice standards. Both statewide strategic planning and the evolving national momentum toward local public health agency accreditation are motivating the enhancements to the Illinois program. A new proposal that blends the current mandatory certification program with a new voluntary local public health accreditation program is discussed. The proposed new structure enhances the state-operated certification program with specific performance measures and creates a three-tiered voluntary accreditation process governed by a third party accreditation board.
