Health and economic impact of HIV/AIDS on South African households: a cohort study

BackgroundSouth African households are severely affected by human immunodeficiency virus / acquired immunodeficiency syndrome (HIV/AIDS) but health and economic impacts have not been quantified in controlled cohort studies.MethodsWe compared households with an HIV-infected member, and unaffected neighbouring households, in one rural and one urban area in Free State province, South Africa. Interviews were conducted with one key informant in each household, at baseline and six months later. We studied 1913 members of 404 households, with 94% and 96% follow up, respectively. Household and individual level analyses were done.ResultsMembers of affected households, compared to members of unaffected households, were independently more likely to be continuously ill (adjusted odds ratio (OR) 2.1, 95% CI 1.3–3.4 at follow up), and to die (adjusted OR 3.4, 95% CI 1.0–11), mainly due to infectious diseases. Government clinics and hospitals were the main sources of health care. Affected households were poorer than unaffected households at baseline (relative income per person 0.61, 95% CI 0.49–0.76). Over six months expenditure and income decreased more rapidly in affected than in unaffected households (baseline-adjusted relative expenditure 0.86, 95% CI 0.75–0.99 and income 0.89, 95% CI 0.75–1.05). Baseline morbidity was independently associated with lower income and expenditure at baseline but not with changes over six months.ConclusionsHIV/AIDS affects the health and wealth of households as well as infected individuals, aggravating pre-existing poverty.

Effect of educational outreach to nurses on tuberculosis case detection and primary care of respiratory illness: pragmatic cluster randomised controlled trial

Abstract Objectives To develop and implement an educational outreach programme for the integrated case management of priority respiratory diseases (practical approach to lung health in South Africa; PALSA) and to evaluate its effects on respiratory care and detection of tuberculosis among adults attending primary care clinics. Design Pragmatic cluster randomised controlled trial, with clinics as the unit of randomisation. Setting 40 primary care clinics, staffed by nurse practitioners, in the Free State province, South Africa. Participants 1999 patients aged 15 or over with cough or difficult breathing (1000 in intervention clinics, 999 in control clinics). Intervention Between two and six educational outreach sessions delivered to nurse practitioners by usual trainers from the health department. The emphasis was on key messages drawn from the customised clinical practice guideline for the outreach programme, with illustrative support materials. Main outcome measures Sputum screening for tuberculosis, tuberculosis case detection, inhaled corticosteroid prescriptions for obstructive lung disease, and antibiotic prescriptions for respiratory tract infections. Results All clinics and almost all patients (92.8%, 1856/1999) completed the trial. Although sputum testing for tuberculosis was similar between the groups (22.6% in outreach group v 19.3% in control group; odds ratio 1.22, 95% confidence interval 0.83 to 1.80), the case detection of tuberculosis was higher in the outreach group (6.4% v 3.8%; 1.72, 1.04 to 2.85). Prescriptions for inhaled corticosteroids were also higher (13.7% v 7.7%; 1.90, 1.14 to 3.18) but the number of antibiotic prescriptions was similar (39.7% v 39.4%; 1.01, 0.74 to 1.38). Conclusions Combining educational outreach with integrated case management provides a promising model for improving quality of care and control of priority respiratory diseases, without extra staff, in resource poor settings.

Fisherfolk are among groups most at risk of HIV: cross-country analysis of prevalence and numbers infected.

HIV prevalence in some fishing communities in low and middle-income countries is known to be high relative to national average seroprevalence rates. Most of the studies supporting this claim refer to the men involved in fish-catching operations (fishermen). However they acknowledge that the men and women who work in associated occupations such as fish trading and processing are also vulnerable in part because they are often within the fishermen’s sexual networks. This vulnerability stems from the nature and dynamics of the fish trade and fishing lifestyle in which a number of known or hypothesized ‘risk factors’ converge. (excerpt)

Self reported receipt of care consistent with 32 quality indicators: national population survey of adults aged 50 or more in England.

Objective To assess the receipt of effective healthcare interventions in England by adults aged 50 or more with serious health conditions. Design National structured survey questionnaire with face to face interviews covering medical panel endorsed quality of care indicators for both publicly and privately provided care. Setting Private households across England. Participants 8688 participants in the English longitudinal study of ageing, of whom 4417 reported diagnoses of one or more of 13 conditions. Main outcome measures Percentage of indicated interventions received by eligible participants for 32 clinical indicators and seven questions on patient centred care, and aggregate scores. Results Participants were eligible for 19 082 items of indicated care. Receipt of indicated care varied substantially by condition. The percentage of indicated care received by eligible participants was highest for ischaemic heart disease (83%, 95% confidence interval 80% to 86%), followed by hearing problems (79%, 77% to 81%), pain management (78%, 73% to 83%), diabetes (74%, 72% to 76%), smoking cessation (74%, 71% to 76%), hypertension (72%, 69% to 76%), stroke (65%, 54% to 76%), depression (64%, 57% to 70%), patient centred care (58%, 57% to 60%), poor vision (58%, 54% to 63%), osteoporosis (53%, 49% to 57%), urinary incontinence (51%, 47% to 54%), falls management (44%, 37% to 51%), osteoarthritis (29%, 26% to 32%), and overall (62%, 62% to 63%). Substantially more indicated care was received for general medical (74%, 73% to 76%) than for geriatric conditions (57%, 55% to 58%), and for conditions included in the general practice pay for performance contract (75%, 73% to 76%) than excluded from it (58%, 56% to 59%). Conclusions Shortfalls in receipt of basic recommended care by adults aged 50 or more with common health conditions in England were most noticeable in areas associated with disability and frailty, but few areas were exempt. Efforts to improve care have substantial scope to achieve better health outcomes and particularly need to include chronic conditions that affect quality of life of older people.

Outcomes in patients waiting for antiretroviral treatment in the Free State Province, South Africa: prospective linkage study

Objective:In South Africa, many HIV-infected patients experience delays in accessing antiretroviral therapy (ART). We examined pretreatment mortality and access to treatment in patients waiting for ART. Design:Cohort of HIV-infected patients assessed for ART eligibility at 36 facilities participating in the Comprehensive HIV and AIDS Management (CHAM) program in the Free State Province. Methods:Proportion of patients initiating ART, pre-ART mortality and risk factors associated with these outcomes were estimated using competing risks survival analysis. Results:Forty-four thousand, eight hundred and forty-four patients enrolled in CHAM between May 2004 and December 2007, of whom 22 083 (49.2%) were eligible for ART; pre-ART mortality was 53.2 per 100 person-years [95% confidence interval (CI) 51.8–54.7]. Median CD4 cell count at eligibility increased from 87 cells/μl in 2004 to 101 cells/μl in 2007. Two years after eligibility an estimated 67.7% (67.1–68.4%) of patients had started ART, and 26.2% (25.6–26.9%) died before starting ART. Among patients with CD4 cell counts below 25 cells/μl at eligibility, 48% died before ART and 51% initiated ART. Men were less likely to start treatment and more likely to die than women. Patients in rural clinics or clinics with low staffing levels had lower rates of starting treatment and higher mortality compared with patients in urban/peri-urban clinics, or better staffed clinics. Conclusions:Mortality is high in eligible patients waiting for ART in the Free State Province. The most immunocompromised patients had the lowest probability of starting ART and the highest risk of pre-ART death. Prioritization of these patients should reduce waiting times and pre-ART mortality.

Implementing nurse-initiated and managed antiretroviral treatment (NIMART) in South Africa: a qualitative process evaluation of the STRETCH trial

BackgroundTask-shifting is promoted widely as a mechanism for expanding antiretroviral treatment (ART) access. However, the evidence for nurse-initiated and managed ART (NIMART) in Africa is limited, and little is known about the key barriers and enablers to implementing NIMART programmes on a large scale. The STRETCH (Streamlining Tasks and Roles to Expand Treatment and Care for HIV) programme was a complex educational and organisational intervention implemented in the Free State Province of South Africa to enable nurses providing primary HIV/AIDS care to expand their roles and include aspects of care and treatment usually provided by physicians. STRETCH used a phased implementation approach and ART treatment guidelines tailored specifically to nurses. The effects of STRETCH on pre-ART mortality, ART provision, and the quality of HIV/ART care were evaluated through a randomised controlled trial. This study was conducted alongside the trial to develop a contextualised understanding of factors affecting the implementation of the programme.MethodsThis study was a qualitative process evaluation using in-depth interviews and focus group discussions with patients, health workers, health managers, and other key informants as well as observation in clinics. Research questions focused on perceptions of STRETCH, changes in health provider roles, attitudes and patient relationships, and impact of the implementation context on trial outcomes. Data were analysed collaboratively by the research team using thematic analysis.ResultsNIMART appears to be highly acceptable among nurses, patients, and physicians. Managers and nurses expressed confidence in their ability to deliver ART successfully. This confidence developed slowly and unevenly, through a phased and well-supported approach that guided nurses through training, re-prescription, and initiation. The research also shows that NIMART changes the working and referral relationships between health staff, demands significant training and support, and faces workload and capacity constraints, and logistical and infrastructural challenges.ConclusionsLarge-scale NIMART appears to be feasible and acceptable in the primary level public sector health services in South Africa. Successful implementation requires a comprehensive approach with: an incremental and well supported approach to implementation; clinical guidelines tailored to nurses; and significant health services reorganisation to accommodate the knock-on effects of shifts in practice.Trial registrationISRCTN46836853

The association between older age and receipt of care and outcomes in patients with acute coronary syndromes: a cohort study of the Myocardial Ischaemia National Audit Project (MINAP)

AIMS Older people increasingly constitute a large proportion of the acute coronary syndrome (ACS) population. We examined the relationship of age with receipt of more intensive management and secondary prevention medicine. Then, the comparative association of intensive management (reperfusion/angiography) over a conservative strategy on time to death was investigated by age. METHODS AND RESULTS Using data from 155 818 patients in the national registry for ACS in England and Wales [the Myocardial Ischaemia National Audit Project (MINAP)], we found that older patients were incrementally less likely to receive secondary prevention medicines and intensive management for both ST-elevation myocardial infarction (STEMI) and non-ST elevation myocardial infarction (NSTEMI). In STEMI patients ≥85 years, 55% received reperfusion compared with 84% in those aged 18 to <65 [odds ratio 0.22 (95% CI 0.21, 0.24)]. Not receiving intensive management was associated with worse survival [mean follow-up 2.29 years (SD 1.42)] in all age groups (adjusted for sex, cardiovascular risk factors, co-morbidities, healthcare factors, and case severity), but there was an incremental reduction in survival benefit from intensive management with increasing age. In STEMI patients aged 18-64, 65-74, 75-84, and ≥85, adjusted hazard ratios (HRs) for all-cause mortality comparing conservative treatment to intensive management were 1.98 (1.78, 2.19), 1.65 (1.51, 1.80), 1.62 (1.52, 1.72), and 1.36 (1.27, 1.47), respectively. In NSTEMI patients, the respective HRs were 4.37 (4.00, 4.78), 3.76 (3.54, 3.99), 2.79 (2.67, 2.91), and 1.90 (1.77, 2.04). CONCLUSION We found an incremental reduction in the use of evidence-based therapies with increasing age using a national ACS registry cohort. While survival benefit from more intensive management reduced with older age, better survival was associated with intensive management at all ages highlighting the requirement to improve standard of care in older patients with ACS.

Influence of specialization on the management and outcome of patients with pancreatic cancer

Cancer care is increasingly specialized. Relationships between pancreatic cancer care, mortality and patterns of clinical practice among the full spectrum of patients, including those with irresectable tumours, are not well understood.

Expanding access to ART in South Africa: the role of nurse-initiated treatment.

The South African government’s recent policy decision to expand access to HIV care rapidly and ‘ensure that all the health institutions in the country are ready to receive and assist patients and not just a few accredited ARV centres’ represents a dramatic and welcome about turn on years of hesitation and confusion in the country’s response to the HIV epidemic. In the first 6 years of the antiretroviral therapy (ART) programme, approximately 900 000 people have been started on treatment. In the next 2 - 3 years, the government proposes to initiate treatment in another 1.2 million people. The medical and moral imperative for providing this life-saving treatment to all who need it does not need to be defended, but the limited capacity of the public health sector to achieve this scale of increase raises serious questions about the practicality of this objective. Along with raising the CD4 thresholds for access to treatment and scrapping the antiretroviral site accreditation process, nurse initiation and management of patients on ART (NIM-ART) is under discussion at the national level as a key strategy for expanding access. There are simply not enough doctors in the public sector to introduce and follow up this number of patients. The major load from this increase will therefore have to be shifted to nurses, themselves under severe pressure and in short supply.
