The impact of ART scale upon health workers: evidence from two South African districts

Registered nurses' perceptions regarding nurse-led antiretroviral therapy initiation in Hhohho region, Swaziland

BACKGROUND

Swaziland has the highest HIV prevalence globally. It faces a critical shortage of health workers for addressing the HIV pandemic. To curb this human resource challenge, Swaziland adopted a nurse-driven model for antiretroviral therapy delivery in line with the recommendations of the World Health Organization on task shifting.

OBJECTIVE

The study explored the perceptions of registered nurses on the nurse-led antiretroviral therapy initiation programme in the Hhohho region of Swaziland (NARTIS).

DESIGN

The study utilized a phenomenological design, specifically a phenomenographic design.

SETTING

The study was conducted in ten health facilities in the Hhohho region of Swaziland. These facilities comprised eight clinics, a hospital and a health centre.

PARTICIPANTS

These were registered nurses, trained and certified in the nurse-led antiretroviral therapy initiation programme. The nurses also had experience of working in a nurse-led antiretroviral therapy initiation programme. Eighteen (18) nurses were purposively selected and recruited to participate in the study.

METHODS

Data were collected through open and deep individual interviews guided by a semi-structured interview schedule. The audio-recorded interviews were transcribed and analysed thematically using Sjöström and Dahlgren's approach to data analysis.

RESULTS

Three major themes emerged from the study data: nurses' emotional reactions to the implementation of the NARTIS programme, and influences and overcoming barriers to the programme.

CONCLUSIONS

The study findings have generated insights into this program which is useful for the provision of care to people living with HIV/AIDS in Swaziland. But nurses need support to ensure effective implementation.

IMPLICATION FOR NURSING AND HEALTH POLICY

The study findings have implications for both the practice of the NARTIS programme and health policy development. The development of a health policy that alleviates the barriers to the NARTIS programme can enhance nurses' role and make care provision to people living with HIV/AIDS more effective.

Clinic-level factors influencing patient outcomes on antiretroviral therapy in primary health clinics in South Africa

OBJECTIVES

To explore which clinic-level factors influence treatment outcomes in a multisite antiretroviral therapy (ART) programme in South Africa.

DESIGN

Retrospective cohort study using 36 clinics.

METHODS

We used random effects modelling to investigate clinic-level factors influencing ART outcomes, adjusting for patient-level factors and accounting for clustering at clinic level. Outcomes were unsuppressed viral load (>400 copies/ml) at 24 months after ART start and time to loss to follow-up.

RESULTS

At clinic level, the mean proportion of patients with unsuppressed viral load at 24 months was 16% (range 8-33%). Loss to follow-up was also highly variable across clinics ranging from 3.5 to 23.4/100 person-years. Unsuppressed viral load was associated with a lower doctor-patient ratio [for every 500 patients, compared with >2.6 doctors: <0.7 doctors: adjusted odds ratio (OR) 1.52, 95% confidence interval (CI) 1.04-2.21; 0.7-2.6 doctors, OR 1.33, CI 0.91-1.93, P trend 0.04] after adjustment for patient factors. Combinations of psychosocial support interventions were weakly associated with reduced loss to follow-up [>6 interventions vs. <4 interventions: hazard ratio 0.39 (CI 0.15 - 1.04), P = 0.11]. Flexibility of services, integration of services, staff motivation, staff leadership and location of clinic were not consistently associated with improved outcomes.

CONCLUSION

The dominant clinic-level influences on patient outcomes were doctor : patient ratio, and combination interventions to reduce loss to follow-up. Further research is needed to define optimum staffing levels that are required to roll out ART and the combination intervention that is most effective to reduce loss to follow-up.

Nurse and manager perceptions of nurse initiated and managed antiretroviral therapy (NIMART) implementation in South Africa: a qualitative study

OBJECTIVE

To explore nurse and facility and programme manager perceptions of nurse initiated and managed antiretroviral therapy (NIMART) implementation in Gauteng, South Africa.

DESIGN

In this qualitative study, in-depth interviews and focus group discussions were conducted to gain insight into participants' experiences of NIMART implementation.

SETTING

Participants came from urban, peri-urban and rural primary healthcare clinics in two Gauteng Province municipalities.

PARTICIPANTS

25 nurses and 18 managers who were actively involved in NIMART implementation were purposively sampled.

RESULTS

The findings from this study reveal that, despite encountering numerous challenges including human resources, training and clinical mentoring and health systems issues, NIMART nurses and managers remained optimistic about their work. Study participants felt empowered by their expanded roles. Increased responsibilities associated with NIMART implementation encouraged better use of creative problem-solving and teamwork to facilitate integration of NIMART into existing clinic services. NIMART nurses perceived antiretroviral therapy (ART) patients to be more insightful about their illness, engaged in their HIV treatment and aware of the importance of adherence which enhanced nurse-patient relationships and increased their sense of job satisfaction.

CONCLUSIONS

Although the implementation of NIMART is complex, when NIMART is implemented well, ART access is increased and patient outcomes are improved. Supportive interventions which address the specific challenges faced by nurses providing NIMART now need to be implemented. Attempts should be made to replicate the positive aspects of NIMART implementation identified by participants as this may improve healthcare providers' experiences of task-shifting.

Structural barriers to timely initiation of antiretroviral treatment in Vietnam: findings from six outpatient clinics

In Vietnam, premature mortality due to AIDS-related conditions is commonly associated with late initiation to antiretroviral therapy (ART). This study explores reasons for late ART initiation among people living with HIV (PLHIV) from the perspectives of health care providers and PLHIV. The study was undertaken in six clinics from five provinces in Vietnam. Baseline CD4 counts were collected from patient records and grouped into three categories: very late initiators (≤100 cells/mm(3) CD4), late initiators (100-200 cells/mm(3)) and timely initiators (200-350 cells/mm(3)). Thirty in-depth interviews with patients who started ART and 15 focus group discussions with HIV service providers were conducted and thematic analysis of the content performed. Of 934 patients, 62% started ART very late and 11% initiated timely treatment. The proportion of patients for whom a CD4 count was obtained within six months of their HIV diagnosis ranged from 22% to 72%. The proportion of patients referred to ART clinics by voluntary testing and counselling centres ranged from 1% to 35%. Structural barriers to timely ART initiation were poor linkage between HIV testing and HIV care and treatment services, lack of patient confidentiality and a shortage of HIV/AIDS specialists. If Vietnam's treatment practice is to align with WHO recommendations then the connection between voluntary counselling and testing service and ART clinics must be improved. Expansion and decentralization of HIV/AIDS services to allow implementation at the community level increased task sharing between doctors and nurses to overcome limited human resources, and improved patient confidentiality are likely to increase timely access to HIV treatment services for more patients.
