Identifying what rural health workers in Malawi need to become HIV prevention leaders

Combating HIV stigma in low- and middle-income healthcare settings: a scoping review

INTRODUCTION

Nearly 40 years into the HIV epidemic, the persistence of HIV stigma is a matter of grave urgency. Discrimination (i.e. enacted stigma) in healthcare settings is particularly problematic as it deprives people of critical healthcare services while also discouraging preventive care seeking by confirming fears of anticipated stigma. We review existing research on the effectiveness of stigma interventions in healthcare settings of low- and middle-income countries (LMIC), where stigma control efforts are often further complicated by heavy HIV burdens, less developed healthcare systems, and the layering of HIV stigma with discrimination towards other marginalized identities. This review describes progress in this field to date and identifies research gaps to guide future directions for research.

METHODS

We conducted a scoping review of HIV reduction interventions in LMIC healthcare settings using Embase, Ovid MEDLINE, PsycINFO and Scopus (through March 5, 2020). Information regarding study design, stigma measurement techniques, intervention features and study findings were extracted. We also assessed methodological rigor using the Joanna Briggs Institute checklist for systematic reviews.

RESULTS AND DISCUSSION

Our search identified 8766 studies, of which 19 were included in the final analysis. All but one study reported reductions in stigma following the intervention. The studies demonstrated broad regional distribution across LMIC and many employed designs that made use of a control condition. However, these strengths masked key shortcomings including a dearth of research from the lowest income category of LMIC and a lack of interventions to address institutional or structural determinants of stigma. Lastly, despite the fact that most stigma measures were based on existing instruments, only three studies described steps taken to validate or adapt the stigma measures to local settings.

CONCLUSIONS

Combating healthcare stigma in LMIC demands interventions that can simultaneously address resource constraints, high HIV burden and more severe stigma. Our findings suggest that this will require more objective, reliable and culturally adaptable stigma measures to facilitate meaningful programme evaluation and comparison across studies. All but one study concluded that their interventions were effective in reducing healthcare stigma. Though encouraging, the fact that most studies measured impact using self-reported measures suggests that social desirability may bias results upwards. Homogeneity of study results also hindered our ability to draw substantive conclusions about potential best practices to guide the design of future stigma reduction programmes.

Standard precaution knowledge and adherence: Do Doctors differ from Medical Laboratory Scientists?

Background

Doctors and laboratory scientists are at risk of infection from blood borne pathogens during routine clinical duties. After over 20 years of standard precautions, health care workers knowledge and compliance is not adequate.

Aim

This study is aimed at comparing adherence and knowledge of standard precautions (SP) among Medical Laboratory Scientists (MLSs) and doctors.

Methods

It was a cross sectional study done at University of Nigeria Teaching Hospital, ItukuOzalla. A semi structured pre-tested questionnaire was the study instrument.

Results

General knowledge of SP was high,76.2% in doctors and 67.6% in MLSs although there were differences between the two groups on the knowledge of components of SP. Safe injection practices, use of personal protective equipment as well as safe handling of contaminated equipment or surfaces was higher amongst doctors. Even though more than half of respondents in both groups, 53.1 % among doctors and 58.1% among MLSs had received training on standard precautions, this did not reflect in the practice. MLS reported more use of personal protective equipment such as gloves and coveralls (100% in MLS and 35% of doctors), P<0.001. Recapping of syringes was higher amongst doctors (63.6%) than MLS (55.1%).The doctors practiced better hand hygiene than MLS (P<0.001). Constraints that affected SP included non-availability of PPEs and emergency situations for both groups.

Conclusion

SP knowledge and practice are still low, and as such, there is a need to train doctors and MLS on the components of SP. Policies on SP need to be enforced and facilities for practice regularly supplied.

Hospital outpatient clinics as a potential hazard for healthcare associated infections

Healthcare acquired infections are no longer confined to the hospital environment. Recently, many reported outbreaks have been linked to outpatient settings and attributed to non-adherence to recommended infection-prevention procedures. This study was divided into two parts: The first is a descriptive cross-sectional part, to assess the healthcare personnel's knowledge and compliance with Standard Precautions (SP). The second is an intervention part to assess the role of health education on reducing the level of environmental and reusable medical equipment bacterial contamination. Assessment of the doctors' and nurses' knowledge and compliance with SP was performed using a self-administered questionnaire. Assessment of environmental cleaning (EC) and reusable medical equipment disinfection has been performed using aseptic swabbing method. The extent of any growth was recorded according to the suggested standards: (A) Presence of indicator organisms, with the proposed standard being <1cfu/cm(2). These include Staphylococcus aureus (including methicillin-resistant Staphylococcus aureus, MRSA), Enterococci, including vancomycin-resistant Enterococci (VRE) and various multidrug-resistant Gram-negative bacilli. (B) Aerobic colony count, the suggested standard is <5cfu/cm(2). The effect of health education intervention on cleaning and disinfection had been analyzed by comparing the difference in cleaning level before and after interventional education. Good knowledge and compliance scores were found in more than 50% of participants. Primary screening found poor EC and equipment disinfection as 67% and 83.3% of stethoscopes and ultrasound transducers, respectively, were contaminated with indicator organisms. For all indicator organisms, a significant reduction was detected after intervention (p=0.00). Prevalence of MRSA was 38.9% and 16.7%, of the total S. aureus isolates, before and after intervention, respectively. Although 27.8% of the total Enterococcus isolates were VRE before intervention, no VRE isolates were detected after intervention. These differences were significant. Development and monitoring of the implementation of infection prevention policies and training of HCP is recommended.

Infection control and practice of standard precautions among healthcare workers in northern Nigeria

Background:

Healthcare-associated infections (HAIs) have been reported to be a serious problem in the healthcare services as they are common causes of illness and mortality among hospitalized patients including healthcare workers (HCWs). Compliance with these standard precautions has been shown to reduce the risk of exposure to blood and body fluids.

Aims:

This study therefore assesses the level of knowledge and compliance with standard precautions by the various cadre of HCWs and the factors influencing compliance in hospital environment in Nasarawa State, Northern Nigeria.

Settings and Design:

Nasarawa State has a current human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) prevalence rate of 10.0%, which was higher than most states in Nigeria with a high level of illiteracy and ignorance. Majority of the people reside in the rural areas while a few are found in the towns, informal settlements with no direct access to healthcare facilities are common.

Materials and Methods:

This study is an analytical, cross-sectional study. Proportional sampling technique was used to obtain a representative sample and a structured self-administered questionnaire was used to collect relevant information from the healthcare providers working in Nasarawa State from January to February 2009.

Statistical analysis used:

To describe patient characteristics, we calculated proportions and medians. For categorical variables, we compared proportions using chi-square tests. A logistic regression model was produced with infection control as outcome variable to identify associated factors.

Results:

A total of 421 HCWs were interviewed, Majority (77.9%) correctly describe universal precaution and infection control with 19.2, 19.2, and 28.0%, respectively unable to recognize vaccination, postexposure prophylaxis, and surveillance for emerging diseases as standard precaution for infection control. About 70.1% usually wear gloves before handling patients or patients’ care products, 12.6% reported wash their hand before wearing the gloves, 10.7% washed hands after removal of gloves, and 72.4% changed gloves after each patient. Only 3.3% had a sharp disposal system in their various workplaces. Majority (98.6%) of the respondents reported that the major reason for noncompliance to universal precautions is the nonavailability of the equipments. There was a statistically significant difference in the practice of standard precaution among those that were exposed to blood products and body fluid compared to those that had not been exposed in the last 6 months (χ² = 3.96, P = 0.03), public healthcare providers when compared to private health workers (χ² = 22.32, P = 0.001), among those working in secondary and tertiary facilities compared to primary healthcare centers (χ² = 14.64, P = 0.001) and urban areas when compared to rural areas (χ² = 4.06, P = 0.02). The only predictor of practice of standard precaution was exposure to blood and body fluid in the last 6 months odds ratio (OR) = 4.56 (confidence interval (CI) = 1.00-21.28).

Conclusions:

This study implies that inadequate workers’ knowledge and environment related problems, including the lack of protective materials and other equipments and utilities required to ensure safety of HCWs is a crucial issue that need urgent attention. Institution of a surveillance system for hospital acquired infection to improve consistent use of standard precautions among health workers is recommended in Nigeria and other low income countries in Africa.

Changes in clients' care ratings after HIV prevention training of hospital workers in Malawi

OBJECTIVE

To examine the changes in clients' health-care ratings before and after hospital workers received an HIV prevention intervention in Malawi, which increased the workers' personal and work-related HIV prevention knowledge, attitudes and preventive behaviors.

DESIGN

Pre- and post-intervention client surveys.

SETTING

A large urban referral hospital in Malawi.

PARTICIPANTS

Clients at purposefully selected inpatient and outpatient units on designated days (baseline, n = 310 clients; final, n = 683).

INTERVENTION

Ten-session peer-group intervention for health workers focused on HIV transmission, personal and work-related prevention, treating clients and families respectfully and incorporating HIV-related teaching.

MAIN OUTCOME MEASURES

Brief face-to-face clients' interview obtaining ratings of confidentiality of HIV, whether HIV-related teaching occurred and ratings of service quality.

RESULTS

Compared with baseline, at the final survey, clients reported higher confidence about confidentiality of clients' HIV status (83 vs. 75%, P < 0.01) and more clients reported that a health worker talked to them about HIV and AIDS (37 versus 28%, P < 0.01). More clients rated overall health services as 'very good' (five-item mean rating, 68 versus 59%, P < 0.01) and this was true for both inpatients and outpatients examined separately. However, there was no improvement in ratings of the courtesy of laboratory or pharmacy workers or of the adequacy of treatment instructions in the pharmacy.

CONCLUSIONS

HIV prevention training for health workers can have positive effects on clients' ratings of services, including HIV-related confidentiality and teaching, and should be scaled-up throughout Malawi and in other similar countries. Hospitals need to improve laboratory and pharmacy services.

Peer group intervention for HIV prevention among health workers in Chile

We tested the impacts of a professionally assisted peer-group intervention on Chilean health workers' HIV-related knowledge, attitudes, and behaviors using a quasi-experimental design with a pretest and 3-month posttest. Two Santiago suburbs were randomly assigned to the intervention or delayed intervention control condition. Five community clinics per suburb participated. Interested workers at the intervention (n = 262) and control (n = 293) clinics participated and completed both evaluations. At posttest, intervention clinic workers had higher knowledge and more positive attitudes regarding HIV, condoms, stigmatization, and self-efficacy for prevention. They reported more partner discussion about safer sex, less unprotected sex, and more involvement in HIV prevention activities in the clinic and the community, but they did not report fewer sexual partners or more standard precautions behaviors. Because of these positive impacts, the program will become a regular continuing education unit that can be used to meet health-worker licensing requirements.

Improving universal precautions and client teaching for rural health workers: a peer-group intervention

Health workers can contribute to HIV prevention by minimizing HIV transmission in health facilities and increasing client teaching. We offered a peer-group intervention for Malawian rural health workers to build their universal precautions and teaching skills. A quasi-experimental design using independent sample surveys and observations compared health workers in an intervention and delayed intervention control district at baseline and at 15 and 30 months post-intervention. Controlling for demographic factors, the intervention district had more reported HIV teaching at 15 and 30 months and also had higher universal precautions knowledge and fewer needle stick injuries at 30 months. Observations at 15 and 30 months post-intervention showed higher levels of teaching in the intervention district. Observed glove wearing and hand washing were also higher at 30 months. This intervention should be made available for health workers in Malawi and provides a potential model for other high-HIV prevalence countries.

Peer group intervention reduces personal HIV risk for Malawian health workers

PURPOSE

To test a peer group intervention to address personal HIV prevention needs of rural health workers in Malawi.

DESIGN

Using a quasi-experimental design, we compared district health workers in two districts of Malawi that were randomly assigned to either the intervention or delayed control condition. We used independent sample surveys at baseline, 15 months, and 30 months postintervention. Intervention district workers received a peer group intervention after the baseline; control district workers received the delayed intervention after final data collection.

METHODS

The 10-session intervention for primary prevention of HIV infection was based on the primary healthcare model, behavioral change theory, and contextual tailoring based on formative evaluation. Differences in HIV-related knowledge, attitudes, self-efficacy, and behaviors were analyzed using t tests and multiple regression controlling for baseline differences.

FINDINGS

Health workers in the intervention district had higher general HIV knowledge, more positive attitudes about condoms, higher self-efficacy for safer sex, and more involvement in community HIV prevention at both the 15-month and 30-month postintervention survey. At 30 months, intervention district workers also reported less stigmatizing attitudes toward persons living with AIDS, more HIV tests, and lower risky sexual behaviors.

CONCLUSION

The intervention should be sustained in current sites and scaled up for health workers throughout Malawi as part of a multisectoral response to HIV prevention.

CLINICAL RELEVANCE

Incorporating a peer group intervention focused on personal as well as work-related HIV prevention can reduce health workers' risky behaviors in their personal lives, potentially reducing morbidity and mortality and enhancing workforce retention. Reducing stigmatizing attitudes may also improve the quality of health services.

Stigma Related to HIV among Community Health Workers in Chile

PURPOSE: When healthcare workers have stigmatizing attitudes toward people living with HIV it may lead to discriminatory behavior that interferes with prevention, treatment, and care. This research examined the HIV-related stigmatizing attitudes reported by health workers in Santiago, Chile. METHODS: The study used focus group data from the first phase of a larger study to develop and test a HIV prevention intervention for Chilean health workers. Ten focus groups were conducted with Health workers in two communities in Santiago, Chile. Content analysis was used to analyze the data. RESULTS: Two central themes emerged: Societal stigma and discrimination towards people living with HIV and healthcare system's policies related to HIV. Both inaccurate fears of transmission among the general public and Chilean Health workers and societal prejudices against homosexuals contributed to stigmatization and discrimination. CONCLUSIONS: Health workers did not recognize their own stigmatizing attitudes or discriminatory behaviors, but their discussion indicated that these behaviors and attitudes did exist. Healthcare system issues identified included problems with confidentiality due to the desire to inform other health workers about client HIV status. Health workers must be sensitized to the current stigmatization and misinformation associated with HIV and its negative impacts on persons living with HIV and the general community. IMPLICATIONS: All clinical and non-clinical workers at community clinics need mandatory education for HIV prevention that focuses on changing attitudes as well as sharing knowledge. Also, the Chilean law protecting people living with HIV and the confidentiality of their medical care needs to be publicized, along with guidelines for its enactment in clinics and other health facilities.

Process evaluation of HIV prevention peer groups in Malawi: a look inside the black box

This paper reports the process evaluation of a peer group intervention for human immunodeficiency virus (HIV) prevention which had positive outcomes for three target groups in Malawi: rural adults, adolescents and urban hospital workers. The six-session intervention was delivered to small groups of 10-12 participants by 85 trained volunteer peer leaders working in pairs. A descriptive, observational mixed methods design was used with a convenience sample of 294 intervention sessions. Using project records and a conceptually based observation guide, we examined five aspects of the implementation process. The context was favorable, but privacy to discuss sensitive issues was a concern for some groups. In study communities, program reach was 58% of rural adults, 70% of adolescents and nearly all hospital workers. Session records confirmed that all peer groups received the intended six sessions (dose delivered). The dose received was high, as evidenced by high participant engagement in peer group activities. Peer leaders were rated above the median for three indicators of peer group content and process fidelity: session management skills, interpersonal facilitation skills and whether more like a peer group than classroom. Documenting that this HIV prevention peer group intervention was delivered as intended by trained peer volunteers supports widespread dissemination of the intervention.

Strengthening the Uganda nurses' and midwives' association for a motivated workforce

BACKGROUND

The Ugandan Association of Nurses and Midwives (UNANM) is a dynamic proactive community. This survey of nurses, both members and non-members of the association, was implemented in April 2007. It was the first phase of a programme-funded Capacity Project/USAID to strengthen professional associations as part of a strategy to retain nurses.

AIM

To better understand the needs and strengths of the association and to develop policy recommendations on how to strengthen the UNANM to retain nurses in the health sector.

METHODS

Three hundred self-completion questionnaires were distributed, of which 217 (72%) were returned. The participants were 126 non-members and 91 members of the UNANM.

RESULTS

Just over a third of the 91 members rated the UNANM to be very effective in promoting nursing (35%) and information sharing (36%). Non-members want to receive nursing information from the UNANM (89%) and were less critical of the UNANM than members. Respondents were interested in counselling training (83%), research capacity building (80%) and sharing best practice (74%). Nurses under 30 years (12%) look to more experienced peers for guidance on coping in a stressful profession.

CONCLUSION

The nurses lack continuing professional development, mentoring and networking opportunities. Tangible support for communication, nurse education and research is needed and will stimulate the development of nursing in Uganda. Most nurses do not have the means to pay for training, research or travel to attend professional meetings. Motivation to stay in nursing and quality of care can increase through investing in nursing, and this support can be channelled through associations such as the UNANM.

Impact of a peer-group intervention on occupation-related behaviors for urban hospital workers in Malawi

Using a pre- and posttest design with no control group, the authors evaluated the impact of a peer-group intervention on work related knowledge and behavior for health workers at an urban hospital in Malawi. The authors surveyed unmatched random samples of health workers, observed workers on the job, and interviewed clients about hospital services at baseline and at 6 months after the intervention. Universal precautions knowledge, reported hand washing, and reported client teaching were significantly higher at the final evaluation. The outcome differences remained robust in multivariate analyses with controls for demographic factors of age, gender, education, food security, and job category. Observations reported consistently greater use of universal precautions, more respectful interactions, and more client teaching at final evaluation. Patient surveys reported more discussion with health workers about HIV at the final evaluation. Peer-group interventions can prepare health workers in Malawi for HIV prevention and offer a potential model for other African countries.

Impacts of a peer-group intervention on HIV-related knowledge, attitudes, and personal behaviors for urban hospital workers in Malawi

This report describes the effects of a peer-group intervention on Malawian urban hospital workers' HIV-related personal knowledge, attitudes, and behaviors. More than 850 clinical and nonclinical hospital workers received the intervention. Evaluation used independent surveys of a sample of workers at baseline (N = 366) and postintervention (N = 561). Compared with the baseline survey, after the intervention, workers had higher knowledge of HIV transmission and prevention; more positive attitudes including more hope, less stigmatization of persons with HIV, more positive attitudes toward HIV testing and condom use, and higher self-efficacy for practicing safer sex and for community prevention; more reported recent personal HIV tests, more discussion of safer sex with partners, and more reported community HIV prevention activities. However, health workers' risky sexual behaviors did not differ at baseline and postintervention. The intervention should be strengthened to support more sexual risk reduction and be made available to all health workers in Malawi.
