Retention in care for type 2 diabetes management in Sub-Saharan Africa: A systematic review

Awareness, treatment, and control among adults living with arterial hypertension or diabetes mellitus in two rural districts in Lesotho

In Lesotho, the hypertension and diabetes care cascades are unknown. We measured awareness, treatment, and control of hypertension and diabetes among adults ≥18 years and identified factors associated with each step of the cascade, based on data from a population-based, cross-sectional survey in 120 randomly sampled clusters in the districts of Butha-Buthe and Mokhotlong from 1st November 2021 to 31st August 2022. We used multivariable logistic regression to assess associations. Among participants with hypertension, 69.7% (95%CI, 67.2-72.2%, 909/1305) were aware of their condition, 67.3% (95%CI 64.8-69.9%, 878/1305) took treatment, and 49.0% (95%CI 46.3-51.7%, 640/1305) were controlled. Among participants with diabetes, 48.4% (95%CI 42.0-55.0%, 111/229) were aware of their condition, 55.8% (95%CI 49.5-62.3%, 128/229) took treatment, and 41.5% (95%CI 35.1-47.9%, 95/229) were controlled. For hypertension, women had higher odds of being on treatment (adjusted odds ratio (aOR) 2.54, 95% CI 1.78-3.61) and controlled (aOR 2.44, 95%CI 1.76-3.37) than men. Participants from urban areas had lower odds of being on treatment (aOR 0.63, 95% CI 0.44-0.90) or being controlled (aOR 0.63, 95% CI 0.46-0.85). Considerable gaps along the hypertension and diabetes care cascades in Lesotho indicate that access and quality of care for these conditions are insufficient to ensure adequate long-term health outcomes.

Long-term impact of an integrated HIV/non-communicable disease care intervention on patient retention in care and clinical outcomes in East Africa

OBJECTIVE

To describe rates of retention in care and control of hypertension, diabetes and HIV among participants receiving integrated care services for a period of up to 24 months in East Africa.

METHODS

Between 5 October 2018 and 23 June 2019 participants enrolled into a prospective cohort study evaluating the feasibility of integrated care delivery for HIV, diabetes and hypertension from a single point of care in Tanzania and Uganda (MOCCA study). Integrated care clinics were established in 10 primary healthcare facilities and care was provided routinely according to national guidelines. Initial follow-up was 12 months. Outcomes were rates of retention in care, proportions of participants with controlled hypertension (blood pressure <140/90 mmHg), diabetes (fasting blood glucose <7.0 mmol/L) and HIV (plasma viral load <1000 copies/ml). The study coincided with the COVID-19 pandemic response. Afterwards, all participants were approached for extended follow-up by a further 12 months in the same clinics. We evaluated outcomes of the cohort at the end of long-term follow-up.

RESULTS

The MOCCA study enrolled 2273 participants of whom 1911 (84.5%) were retained in care after a median follow-up of 8 months (Interquartile range: 6.8-10.7). Among these, 1283/1911 (67.1%) enrolled for a further year of follow-up, 458 (24.0%) were unreachable, 71 (3.7%) reverted to vertical clinics (clinics providing services dedicated to study conditions), 31 (1.6%) died and 68 (3.6%) refused participation. Among participants who enrolled for longer follow-up, mean age was 51.4 ± 11.7 years, 930 (72.5%) were female and 509 (39.7%) had multiple chronic conditions. Overall, 1236 (96.3%) [95% confidence interval 95.2%-97.3%] participants were retained in care, representing 1236/2273 (54.3%) [52.3%-56.4%] of participants ever enrolled in the study. Controlled hypertension, diabetes and HIV at the end of follow-up was, 331/618 (53.6%) [49.5%-57.5%], 112/354 (31.6%) [26.8%-36.8%] and 332/343 (96.7%) [94.3%-98.4%] respectively.

CONCLUSION

Integrated care can achieve high rates of retention in care long term, but control of blood pressure and blood sugar remains low.

Transfers between health facilities of people living with diabetes attending primary health care services in the Western Cape Province of South Africa: A retrospective cohort study

OBJECTIVES

Transfers between health facilities of people living with HIV attending primary health care (PHC) including hospital to PHC facility, PHC facility to hospital and PHC facility to PHC facility transfers occur frequently, affect health service planning, and are associated with disengagement from care and viraemia. Data on transfers among people living with diabetes attending PHC, particularly transfers between PHC facilities, are few. We assessed the transfer incidence rate of people living with diabetes attending PHC, and the association between transfers between PHC facilities and subsequent HbA1c values.

METHODS

We analysed data on HbA1c tests at public sector facilities in the Western Cape Province (2016-March 2020). Individuals with an HbA1c in 2016-2017 were followed-up for 27 months and included in the analysis if ≥18 years at first included HbA1c, ≥2 HbA1cs during follow-up and ≥1 HbA1c at a PHC facility. A visit interval was the duration between two consecutive HbA1cs. Successive HbA1cs at different facilities of any type indicated any transfer, and HbA1cs at different PHC facilities indicated a transfer between PHC facilities. Mixed effects logistic regression adjusted for sex, age, rural/urban facility attended at the start of the visit interval, disengagement (visit interval >14 months) and a hospital visit during follow-up assessed the association between transfers between PHC facilities and HbA1c >8%.

RESULTS

Among 102,813 participants, 22.6% had ≥1 transfer of any type. Including repeat transfers, there were 29,994 transfers (14.4 transfers per 100 person-years, 95% confidence interval [CI] 14.3-14.6). A total of 6996 (30.1%) of those who transferred had a transfer between PHC facilities. Visit intervals with a transfer between PHC facilities were longer (349 days, interquartile range [IQR] 211-503) than those without any transfer (330 days, IQR 182-422). The adjusted relative odds of an HbA1c ≥8% after a transfer between PHC facilities versus no transfer were 1.20 (95% CI 1.05-1.37).

CONCLUSION

The volume of transfers involving PHC facilities requires consideration when planning services. Individuals who transfer between PHC facilities require additional monitoring and support.

Implementation of Kidney Biopsy in One of the Poorest Countries in the World: Experience from Zinder Hospital (Niger)

Kidney biopsy (KB) has become essential in the nephrologist's approach to kidney diseases, both for diagnosis, treatment, and prognosis. Our objective is to describe the preliminary results of KBs in Niger, one of the poorest countries in the world. This is a descriptive cross-sectional study that took place over 36 months in the nephrology/dialysis department of the Zinder National Hospital. Biopsy results were obtained in less than 5 working days. Patients were responsible for covering the cost of the kidney biopsy. The data collected were analyzed using Epi Info V7 software. We performed 120 kidney biopsies during the study period. The average age of the patients was 35 years ± 15.4 [5-68]. The male/female sex ratio was 2:1. Patients' medical history included herbal medicine use in 33% of cases and high blood pressure in 27.5% of cases. Proteinuria was present at a rate of ≥3 g/24 h in 46.6% of them. The primary indication for kidney biopsy was glomerular syndrome in 62.5% of cases, including 50% with nephrotic syndrome. All kidney biopsies were performed with real-time ultrasound guidance, using an automatic gun fitted with a 16G needle. Regarding complications, macroscopic hematuria was present in 12.5% of cases. Inadequate kidney biopsy was infrequent (5.8% of cases). The most common findings were (i) glomerular diseases (58.4%), such as membranoproliferative glomerulonephritis (13.3%), focal-segmental glomerulosclerosis (10.6%), lupus nephritis (8.8%), minimal change disease (8%), and membranous nephropathy (2.7%), and (ii) tubulointerstitial changes (31.8%). Diabetic nephropathy was rare (2.6%), as was IgA nephropathy (0.9%). We have demonstrated that implementing a sustainable kidney biopsy program in a very poor country is feasible, thanks to the dedication of a specialized renal pathologist. Having a clear diagnosis can assist in properly treating these renal patients according to international guidelines, thereby delaying the progression to end-stage kidney disease.

Population confidence in the health system in 15 countries: results from the first round of the People's Voice Survey

Population confidence is essential to a well functioning health system. Using data from the People's Voice Survey-a novel population survey conducted in 15 low-income, middle-income, and high-income countries-we report health system confidence among the general population and analyse its associated factors. Across the 15 countries, fewer than half of respondents were health secure and reported being somewhat or very confident that they could get and afford good-quality care if very sick. Only a quarter of respondents endorsed their current health system, deeming it to work well with no need for major reform. The lowest support was in Peru, the UK, and Greece-countries experiencing substantial health system challenges. Wealthy, more educated, young, and female respondents were less likely to endorse the health system in many countries, portending future challenges for maintaining social solidarity for publicly financed health systems. In pooled analyses, the perceived quality of the public health system and government responsiveness to public input were strongly associated with all confidence measures. These results provide a post-COVID-19 pandemic baseline of public confidence in the health system. The survey should be repeated regularly to inform policy and improve health system accountability.

Integrated management of HIV, diabetes, and hypertension in sub-Saharan Africa (INTE-AFRICA): a pragmatic cluster-randomised, controlled trial

BACKGROUND

In sub-Saharan Africa, health-care provision for chronic conditions is fragmented. The aim of this study was to determine whether integrated management of HIV, diabetes, and hypertension led to improved rates of retention in care for people with diabetes or hypertension without adversely affecting rates of HIV viral suppression among people with HIV when compared to standard vertical care in medium and large health facilities in Uganda and Tanzania.

METHODS

In INTE-AFRICA, a pragmatic cluster-randomised, controlled trial, we randomly allocated primary health-care facilities in Uganda and Tanzania to provide either integrated care or standard care for HIV, diabetes, and hypertension. Random allocation (1:1) was stratified by location, infrastructure level, and by country, with a permuted block randomisation method. In the integrated care group, participants with HIV, diabetes, or hypertension were managed by the same health-care workers, used the same pharmacy, had similarly designed medical records, shared the same registration and waiting areas, and had an integrated laboratory service. In the standard care group, these services were delivered vertically for each condition. Patients were eligible to join the trial if they were living with confirmed HIV, diabetes, or hypertension, were aged 18 years or older, were living within the catchment population area of the health facility, and were likely to remain in the catchment population for 6 months. The coprimary outcomes, retention in care (attending a clinic within the last 6 months of study follow-up) for participants with either diabetes or hypertension (tested for superiority) and plasma viral load suppression for those with HIV (>1000 copies per mL; tested for non-inferiority, 10% margin), were analysed using generalised estimating equations in the intention-to-treat population. This trial is registered with ISCRTN 43896688.

FINDINGS

Between June 30, 2020, and April 1, 2021 we randomly allocated 32 health facilities (17 in Uganda and 15 in Tanzania) with 7028 eligible participants to the integrated care or the standard care groups. Among participants with diabetes, hypertension, or both, 2298 (75·8%) of 3032 were female and 734 (24·2%) of 3032 were male. Of participants with HIV alone, 2365 (70·3%) of 3365 were female and 1000 (29·7%) of 3365 were male. Follow-up lasted for 12 months. Among participants with diabetes, hypertension, or both, the proportion alive and retained in care at study end was 1254 (89·0%) of 1409 in integrated care and 1457 (89·8%) of 1623 in standard care. The risk differences were -0·65% (95% CI -5·76 to 4·46; p=0·80) unadjusted and -0·60% (-5·46 to 4·26; p=0·81) adjusted. Among participants with HIV, the proportion who had a plasma viral load of less than 1000 copies per mL was 1412 (97·0%) of 1456 in integrated care and 1451 (97·3%) of 1491 in standard care. The differences were -0·37% (one-sided 95% CI -1·99 to 1·26; pnon-inferiority<0·0001 unadjusted) and -0·36% (-1·99 to 1·28; pnon-inferiority<0·0001 adjusted).

INTERPRETATION

In sub-Saharan Africa, integrated chronic care services could achieve a high standard of care for people with diabetes or hypertension without adversely affecting outcomes for people with HIV.

'The solution is we need to have a centre': a study on diabetes in Liberia

In Liberia, one of the poorest nations in sub-Saharan Africa, the burden of diabetes is a growing concern. The high mortality and morbidity associated with diabetes have significant implications for individuals, families and society at large. The aim of this critical hermeneutic study was to explore what it is like to live with diabetes in Liberia. We recruited 10 participants from Monrovia, Liberia to partake in this study. Photovoice, a well-established participatory data collection approach was used to gather images and stories that represented participants' everyday experiences of living with diabetes. Three major themes were uncovered, highlighting the strengths, challenges and solutions related to living with diabetes in Liberia: strengths-engagement in diabetes self-management practices, focused on participants' commitment to engage in diabetes self-management practices despite the socioeconomic challenges they experienced; challenges-lack of social and economic support, focused on limited access to food, diabetes medications and supplies and diabetes education; and solutions-centre for diabetes education, care and support, focused on participants' recommendations for a community-based diabetes centre, a single point of access for meeting the needs of people with diabetes. A strong commitment to prioritize diabetes on Liberia's national health agenda and increased resources for diabetes care is needed to address the challenges experienced by people living with this chronic disease in Liberia.
