Risk Factors, Epidemiology and Outcome of Acute Kidney Injury among Pediatric Admissions in a Primary Health Facility in Cameroon

Background and aim: Little is known about what happens in primary health structures without nephrology care, especially in the paediatric population. We sought describe the epidemiology of AKI in children at risk in district hospitals in Cameroon. Methods: We prospectively screened consenting children aged 2-18 years of age in paediatric wards of 3 large urban district hospitals over a period of 4 months. Participants with AKI were then followed up till discharge. Outcomes of interest were need and access to dialysis, and renal recovery on hospital discharge. Written assent was obtained from parents or caregivers. Results: Among the 211 children admitted during the study period, 82% (n=173) were at risk of AKI, of whom 19 (11%) did not consent. Of the 154 children included 54.5% were males and the median age was 6 years [IQ 3-10]. Sepsis and volume depletion were the most common risk factors of AKI. The incidence of AKI was 12.3% (n=19). AKI was mostly community acquired and 47.4% (n=9) patients were in KDIGO stage 3. Pre-renal AKI and acute tubular necrosis accounted for 63.2% and 36.8% respectively. Gastro-intestinal losses, malaria, bacterial sepsis and nephrotoxins were the common aetiologies of AKI. On discharge, 71.7% of AKI had complete recovery renal function. Conclusion: Risk factors of AKI are very common in children on admission in general district hospitals in Cameroon. Efforts should be made to raise awareness of primary health caregivers about risk assessment, prevention, early recognition and management of AKI in children.

Difficulties of unit managers in selected district hospitals in Cameroon.

BackgroundBeing appointed to a managerial position because of one’s clinical skills seems to be prestigious, even powerful. However, being a unit manager in a resource-constrained district hospital can be a daunting task. Also, managing a ward unit with no previous training in leadership and management can be very challenging.ObjectivesThe purpose of this study was to describe the difficulties, in the day-to-day activities, of unit managers in selected Cameroonian district hospitals.MethodA constructionist, descriptive Husserlian phenomenological inquiry was conducted to describe the difficulties of unit managers in two district hospitals. Ten unit managers were selected through a purposive sampling scheme, and then interviewed using semi-structured interviews. Coliazzi’s qualitative data analysis method was used for analysis.ResultsThis study revealed that unit managers looked for assistance because it is not easy to be in their position. Their role implied facing difficulties and making sacrifices for something that is not even worth the trouble. Therefore, as a way to overcome their difficulties, they asked for assistance from the organisation, from their families and from God as strategies to face their difficulties.ConclusionThe difficulties faced by unit managers in the selected district hospitals revealed the need to prepare nurses for managerial positions by ensuring they are trained as managers before commencing employment as a manager.

Mortality of head injuries in Sub-Saharan African countries: The case of the university teaching hospitals of Cameroon

BackgroundReliable data on severe head injury mortality is rarely reported in Sub-Saharan African countries and in Cameroon in particular. It was for this reason that for the first time ever a prospective study was carried out during a one year period in the university hospitals and some selected regional and district hospitals in Cameroon. Materials and methodsAll the patients admitted for head injury in the emergency units of the selected hospitals were enrolled and followed up over a period of one month. ResultsA total of 2835 consecutive patients were included with a sex ratio M/F=3.7/1. One hundred and seventy nine (179) patients lost to follow up were not included. The mortality rate was 77% in the severe head injury group, 16% in the moderate head injury group and 1% in the mild head injury group. In the group of severely injured patients, the mortality rates were very high in the academic hospitals (Laquintinie Hospital of Douala, General Hospital of Douala, Yaounde Central Hospital, and Yaounde University Hospital; 83%, 83%, 81%, and 73% respectively) and in the Regional Hospital of Garoua (84%). ConclusionMortality rates associated with head injury remain very high in Cameroon, and this is likely true in many countries across Sub-Saharan Africa. The figures approach the mortality expected in the natural history of the disease. Strategic plans should be taken at the local and national levels as in the case of maternal mortality and HIV infections.

Le programme national de lutte contre le VIH/sida renforce-t-il les hôpitaux de district au Cameroun ?

The aim of this study was to investigate the effects of the national HIV/AIDS control programme on district hospitals in Cameroon. A multiple case study was conducted in two district hospitals- one public and one faith-based. Data were collected by document review, semi-structured interviews and observation of managerial processes and health care delivery. Programme interventions result in a series of positive and negative effects on the functioning of district hospitals and local health systems. High input and support of staff skills were observed for antiretroviral therapy and the management of opportunistic infections. However, the impact of the programme on the stewardship function is problematic. The low implication of district management teams in the implementation of HIV /AIDS activities reduces their structural capacity to run the local health systems. Programme and health system managers failed to take advantage of opportunities to develop synergies between the HIV/AIDS programme and local health systems. The HIV/AIDS programme weakens the systemic and structural capacity of local health systems. Managers of both programmes and general health systems should analyse and adapt their interventions in order to effective' strengthen health systems. One of the research questions is to understand why health system stakeholders do not seize opportunities to develop synergies between programmes and the general system and to strengthen health systems.

Gender Differences in Adherence and Response to Antiretroviral Treatment in the Stratall Trial in Rural District Hospitals in Cameroon.

Evidence of gender differences in antiretroviral treatment (ART) outcomes in sub-Saharan Africa is conflicting. Our objective was to assess gender differences in (1) adherence to ART and (2) virologic failure, immune reconstitution, mortality, and disease progression adjusting for adherence. Cohort study among 459 ART-naive patients followed up 24 months after initiation in 2006-2010 in 9 rural district hospitals. Adherence to ART was assessed using (1) a validated tool based on multiple patient self-reports and (2) antiretroviral plasma concentrations. The associations between gender and the outcomes were assessed using multivariate mixed models or accelerated time failure models. One hundred thirty-five patients (29.4%) were men. At baseline, men were older, had higher body mass index and hemoglobin level, and received more frequently efavirenz than women. Gender was not associated with self-reported adherence (P = 0.872, 0.169, and 0.867 for moderate adherence, low adherence, and treatment interruption, respectively) or with antiretroviral plasma concentrations (P = 0.549 for nevirapine/efavirenz). In contrast, male gender was associated with virologic failure [odds ratio: 2.18, 95% confidence interval (CI): 1.31 to 3.62, P = 0.003], lower immunologic reconstitution (coefficient: -58.7 at month 24, 95% CI: -100.8 to -16.6, P = 0.006), and faster progression to death (time ratio: 0.30, 95% CI: 0.12 to 0.78, P = 0.014) and/or to World Health Organization stage 4 event (time ratio: 0.27, 95% CI: 0.09 to 0.79, P = 0.017). Our study provides important evidence that African men are more vulnerable to ART failure than women and that the male vulnerability extends beyond adherence issues. Additional studies are needed to determine the causes for this vulnerability to optimize HIV care. However, personalized adherence support remains crucial.

Benefits of task-shifting HIV care to nurses in terms of health-related quality of life in patients initiating antiretroviral therapy in rural district hospitals in Cameroon [Stratall Agence Nationale de Recherche sur le SIDA (ANRS) 12110/Ensemble pour une Solidarité Thérapeutique Hospitalière en Réseau (ESTHER) substudy

The World Health Organization (WHO) recommends task-shifting HIV care to nurses in low-resource settings with limited numbers of physicians. However, the effect of such task-shifting on the health-related quality of life (HRQL) of people living with HIV (PLHIV) has seldom been evaluated. We aimed to investigate the effect of task-shifting HIV care to nurses on HRQL outcomes in PLHIV initiating antiretroviral therapy (ART) in rural district hospitals in Cameroon. Outcomes in PLHIV were longitudinally collected in the 2006-2010 Stratall trial. PLHIV were followed up for 24 months by nurses and/or physicians. Six HRQL dimensions were assessed during face-to-face interviews using the WHO Quality of Life (WHOQOL)-HIV BREF scale: physical health; psychological health; independence level; social relationships; environment; and spirituality/religion/personal beliefs. The degree of task-shifting was estimated using a consultant ratio (i.e. the ratio of nurse-led to physician-led visits). The effect of task-shifting and other potential correlates on HRQL dimensions was explored using a Heckman two-stage approach based on linear mixed models to adjust for the potential bias caused by missing data in the outcomes. Of 1424 visits in 440 PLHIV (70.5% female; median age 36 years; median CD4 count 188 cells/μL at enrolment), 423 (29.7%) were task-shifted to nurses. After multiple adjustment, task-shifting was associated with higher HRQL level for four dimensions: physical health [coefficient 0.7; 95% confidence interval (CI) 0.1-1.2; P = 0.01], psychological health (coefficient 0.5; 95% CI 0.0-1.0; P = 0.05), independence level (coefficient 0.6; 95% CI 0.1-1.1; P = 0.01) and environment (coefficient 0.6; 95% CI 0.1-1.0; P = 0.02). Task-shifting HIV care to nurses benefits the HRQL of PLHIV. Together with the previously demonstrated comparable clinical effectiveness of physician-based and nurse-based models of HIV care, our results support the WHO recommendation for task-shifting.

Compliance of district hospitals in the Center Region of Cameroon with WHO/IATSIC guidelines for the care of the injured: a cross-sectional analysis.

Injuries are a major cause of death and disability worldwide. Low-income countries, particularly in Africa, are disproportionately affected. The burden of injuries can be alleviated by preventive measures and appropriate management of injury cases. African countries generally lack trauma care systems based on reliable and affordable guidelines. The aim of this study was to assess the compliance of some district hospitals in Cameroon with World Health Organization/International Association for Trauma and Intensive Care (WHO/IATSIC) guidelines for care of the injured. This cross-sectional descriptive survey used items from the WHO/IATSIC "Guidelines for Essential Trauma Care" to develop a checklist for inspection of physical equipment and a questionnaire assessing human resources and organizational capabilities in 25 district hospitals of the Center Region of Cameroon. All hospitals surveyed had at least one doctor available. Each reported treating a mean of 338±214 injury cases every year. Most hospitals (n=22) were globally either not compliant or partly compliant with the guidelines. Staff generally had received the appropriate basic training but had no additional training specifically directed toward trauma management. Skills for managing specific injuries (e.g., chest injuries) were poor. Availability and utilization of equipment was globally inadequate, and organizational capabilities were almost nonexistent. District hospitals of the Center Region of Cameroon still lack compliance with the WHO/IATSIC guidelines for essential trauma care but have significant potential for improvement. It seems possible to optimize the utilization of existing facilities.

Correction: Susceptibility to Transmitting HIV in Patients Initiating Antiretroviral Therapy in Rural District Hospitals in Cameroon (Stratall ANRS 12110/ESTHER Trial)

Correction: Susceptibility to Transmitting HIV in Patients Initiating Antiretroviral Therapy in Rural District Hospitals in Cameroon (Stratall ANRS 12110/ESTHER Trial)

Susceptibility to Transmitting HIV in Patients Initiating Antiretroviral Therapy in Rural District Hospitals in Cameroon (Stratall ANRS 12110/ESTHER Trial)

ObjectivesUsing cohort data nested in a randomized trial conducted in Cameroon, this study aimed to investigate time trends and predictors of the susceptibility to transmitting HIV during the first 24 months of treatment.MethodsThe outcome, susceptibility to transmitting HIV, was defined as reporting inconsistent condom use and experiencing incomplete virological suppression. Mixed logistic regressions were performed to identify predictors of this outcome among 250 patients reporting to have had sexual relationships either with HIV-negative or unknown HIV status partner(s).ResultsDespite an initial decrease from 76% at M0 to 50% at M6, the rate of inconsistent condom use significantly increased from M12 (59%) to M24 (66%) (p = 0.017). However, the proportion of patients susceptible to transmitting HIV significantly decreased over follow-up from 76% at M0, to 50% at M6, 31% at M12 and 27% at M24 (p<0.001). After controlling for age, gender and intervention group, we found that perceiving healthcare staff’s readiness to listen as poor (adjusted odds ratios (AOR) [95% Confidence Interval (CI)] = 1.87 [1.01–3.46]), reporting to have sexual relationships more than once per week (AOR [95%CI] = 2.52 [1.29–4.93]), having more than one sexual partner (AOR [95%CI] = 2.53 [1.21–5.30]) and desiring a/another child (AOR [95%CI] = 2.07 [1.10–3.87]) were all associated with a higher risk of being susceptible to transmitting HIV. Conversely, time since ART initiation (AOR [95%CI] = 0.66 [0.53–0.83] for an extra 6 months and ART adherence (AOR [95%CI] = 0.33 [0.15–0.72]) were significantly associated with a lower risk of being susceptible to transmitting HIV.ConclusionsThe decrease observed in the susceptibility to transmitting HIV suggests that fear of behavioural disinhibition should not be a barrier to universal access to ART. However, developing adequate preventive interventions matching patients’ expectations -like the desire to have children- and strengthening healthcare staff’s counselling skills are urgently needed to maximize the impact of ART in slowing the HIV epidemic.

Task shifting HIV care in rural district hospitals in Cameroon: evidence of comparable antiretroviral treatment-related outcomes between nurses and physicians in the Stratall ANRS/ESTHER trial.

Task shifting to nurses for antiretroviral therapy (ART) is promoted by the World Health Organization to compensate for the severe shortage of physicians in Africa. We assessed the effectiveness of task shifting from physicians to nurses in rural district hospitals in Cameroon. We performed a cohort study using data from the Stratall trial, designed to assess monitoring strategies in 2006-2010. ART-naive patients were followed up for 24 months after treatment initiation. Clinical visits were performed by nurses or physicians. We assessed the associations between the consultant ratio (ie, the ratio of the number of nurse-led visits to the number of physician-led visits) and HIV virological success, CD4 recovery, mortality, and disease progression to death or to the World Health Organization clinical stage 4 in multivariate analyses. Of the 4141 clinical visits performed in 459 patients (70.6% female, median age 37 years), a quarter was task shifted to nurses. The consultant ratio was not significantly associated with virological success [odds ratio 1.00, 95% confidence interval (CI): 0.59 to 1.72, P = 0.990], CD4 recovery (coefficient -3.6, 95% CI: -35.6; 28.5, P = 0.827), mortality (time ratio 1.39, 95% CI: 0.27 to 7.06, P = 0.693), or disease progression (time ratio 1.60, 95% CI: 0.35 to 7.37, P = 0.543). This study brings important evidence about the comparability of ART-related outcomes between HIV models of care based on physicians or nurses in resource-limited settings. Investing in nursing resources for the management of noncomplex patients should help reduce costs and patient waiting lists while freeing up physician time for the management of complex cases, for mentoring and supervision activities, and for other health interventions.

The interface between the national tuberculosis control programme and district hospitals in Cameroon: missed opportunities for strengthening the local health system –a multiple case study

BackgroundTuberculosis remains a major public health problem in sub-Saharan Africa. District hospitals (DHs) play a central role in district-based health systems, and their relation with vertical programmes is very important. Studies on the impact of vertical programmes on DHs are rare. This study aims to fill this gap. Its purpose is to analyse the interaction between the National Tuberculosis Control Programme (NTCP) and DHs in Cameroon, especially its effects on the human resources, routine health information system (HIS) and technical capacity at the hospital level.MethodsWe used a multiple case study methodology. From the Adamaoua Region, we selected two DHs, one public and one faith-based. We collected qualitative and quantitative data through document reviews, semi-structured interviews with district and regional staff, and observations in the two DHs.ResultsThe NTCP trained and supervised staff, designed and provided tuberculosis data collection and reporting tools, and provided anti-tuberculosis drugs, reagents and microscopes to DHs. However, these interventions were limited to the hospital units designated as Tuberculosis Diagnostic and Treatment Centres and to staff dedicated to tuberculosis control activities. The NTCP installed a parallel HIS that bypassed the District Health Services. The DH that performs well in terms of general hospital care and that is well managed was successful in tuberculosis control. Based on the available resources, the two hospitals adapt the organisation of tuberculosis control to their settings. The management teams in charge of the District Health Services are not involved in tuberculosis control. In our study, we identified several opportunities to strengthen the local health system that have been missed by the NTCP and the health system managers.ConclusionWell-managed DHs perform better in terms of tuberculosis control than DHs that are not well managed. The analysis of the effects of the NTCP on the human resources, HIS and technical capacity of DHs indicates that the NTCP supports, rather than strengthens, the local health system. Moreover, there is potential for this support to be enhanced. Positive synergies between the NTCP and district health systems can be achieved if opportunities to strengthen the district health system are seized. The question remains, however, of why managers do not take advantage of the opportunities to strengthen the health system.

Impact of HIV Comprehensive Care and Treatment on Serostatus Disclosure among Cameroonian Patients in Rural District Hospitals

This work aimed to analyze the rate of disclosure to relatives and friends over time and to identify factors affecting disclosure among seropositive adults initiating antiretroviral therapy (ART) in rural district hospitals in the context of decentralized, integrated HIV care and task-shifting to nurses in Cameroon. Stratall was a 24-month, randomized, open-label trial comparing the effectiveness of clinical monitoring alone with laboratory plus clinical monitoring on treatment outcomes. It enrolled 459 HIV-infected ART-naive adults in 9 rural district hospitals in Cameroon. Participants in both groups were sometimes visited by nurses instead of physicians. Patients with complete data both at enrolment (M0) and at least at one follow-up visit were included in the present analysis. A mixed Poisson regression was used to estimate predictors of the evolution of disclosure index over 24 months (M24).The study population included 385 patients, accounting for 1733 face-to-face interviews at follow-up visits from M0 to M24. The median [IQR] number of categories of relatives and friends to whom patients had disclosed was 2 [1]–[3] and 3 [2]–[5] at M0 and M24 (p-trend<0.001), respectively. After multiple adjustments, factors associated with disclosure to a higher number of categories of relatives and friends were as follows: having revealed one’s status to one’s main partner, time on ART, HIV diagnosis during hospitalization, knowledge on ART and positive ratio of follow-up nurse-led to physician-led visits measuring task-shifting. ART delivered in the context of decentralized, integrated HIV care including task-shifting was associated with increased HIV serological status disclosure.

Changes in sexual activity and risk behaviors among PLWHA initiating ART in rural district hospitals in Cameroon – Data from the STRATALL ANRS 12110/ESTHER trial

The continued scaling-up of antiretroviral therapy (ART) in Sub-Saharan Africa provides an opportunity to further study its impact on sexual behaviors among people living with HIV/AIDS (PLWHA). We explored time trend and correlates of sexual activity among PLWHA initiating ART in Cameroon and compared sexual risk behaviors between patients sexually active before and after initiating ART and those resuming sexual activity after ART initiation. Analyses were based on longitudinal data collected within the randomized trial (n = 459) conducted in nine rural district hospitals in Cameroon. Sexual activity was defined as reporting at least one sexual partner during the previous 3 months. Inconsistent condom use (ICU) was defined as reporting to have “never,” “sometimes,” or “nearly always” used condoms at least once with a partner(s) either HIV-negative or of unknown HIV status during the same period. Mc Nemar tests were used to assess time trend, while mixed-effect logistic regressions were conducted to analyze the effect of time since ART initiation on sexual activity. The proportion of sexually active patients significantly increased over time: from 31.8% at baseline to 40.2 and 47.1% after 6 and 12 months of ART, respectively (p=0.001), to 55.9% after 24 months (p=0.02). After adjustment for behavioral and psychosocial factors, time since ART initiation was independently associated with reporting sexual activity (AOR [95% CI] = 1.30 [1.17–1.46] per 6-month increase, p=0.001). ICU was more frequent among patients sexually active both before and after ART initiation than among those who resumed sexual activity after ART initiation (82 vs. 59%, p<0.001). To conclude, while ART initiation fosters resumption of sexual activity in patients who are inactive before starting treatment; unsafe sexual behaviors remain less frequent in this population than in patients who are already sexually active before starting ART. Risk reduction programs should be reinforced among PLWHA in the context of ART scaling-up.

Monitoring of HIV viral loads, CD4 cell counts, and clinical assessments versus clinical monitoring alone for antiretroviral therapy in rural district hospitals in Cameroon (Stratall ANRS 12110/ESTHER): a randomised non-inferiority trial

Scaling up of antiretroviral therapy in low-resource countries is done on the basis of decentralised, integrated HIV care in rural facilities; however, laboratory monitoring is generally unavailable. We aimed to assess the effectiveness and safety of clinical monitoring alone (CLIN) in terms of non-inferiority to laboratory and clinical monitoring (LAB). We did a randomised, open-label, non-inferiority trial in nine rural district hospitals in Cameroon. Eligible participants were adults (≥18 years) infected with HIV-1 group M (WHO disease stage 3-4) who had not previously received antiretroviral therapy, and were followed-up for 2 years by health-care workers in routine activities. We randomly assigned participants (1:1) to CLIN or LAB (counts of HIV viral load and CD4 cell every 6 months) groups with a computer-generated list. The primary outcome was non-inferiority of CLIN to LAB in terms of increase in CD4 cell count with a non-inferiority margin of 25%. We did all analyses in participants who attended at least one follow-up visit. This trial is registered with ClinicalTrials.gov, number NCT00301561. 238 (93%) of 256 participants assigned to CLIN and 221 (93%) of 237 assigned to LAB were eligible for analysis. CLIN was not non-inferior to LAB; the mean increase in CD4 cell count was 175 cells per μL (SD 190, 95% CI 151-200) with CLIN and 206 (190, 181-231) with LAB (difference -31 [-63 to 2] and non-inferiority margin -52 [-58 to -45]). Furthermore, in the predefined secondary outcome of treatment changes, 13 participants (6%) in the LAB group switched to second-line regimens whereas no participants in the CLIN group did so (p<0·0001). By contrast, other predefined secondary outcomes were much the same in both groups-viral suppression (<40 copies per mL; 465 [49%] of 952 measurements in CLIN vs 456 [52%] of 884 in LAB), HIV resistance (23 [10%] of 238 participants vs 22 [10%] of 219 participants), mortality (44 [18%] of 238 vs 32 [14%] of 221), disease progression (85 [36%] of 238 vs 64 [29%] of 221), adherence (672 [63%] of 1067 measurements vs 621 [61%] of 1011), loss to follow-up (21 [9%] of 238 vs 17 [8%] of 221), and toxic effects (46 [19%] of 238 vs 56 [25%] of 221). Our findings support WHO's recommendation for laboratory monitoring of antiretroviral therapy. However, the small differences that we noted between the strategies suggest that clinical monitoring alone could be used, at least temporarily, to expand antiretroviral therapy in low-resource settings.

WHO clinical criteria-based initiation of antiretroviral therapy: lessons from rural district hospitals in Cameroon with regard to 2009 revised WHO recommendations

To assess the proportion of patients infected with HIV with a CD4 count above 350 cells/mm(3) among those classified at WHO clinical stage 3 or 4 who initiated antiretroviral therapy in rural district hospitals in Cameroon to assess the 2009 revised WHO recommendations. Cross-sectional study in nine rural district hospitals where the treatment initiation is based on the WHO clinical criteria. The proportion of patients who were classified at stage 3 or 4 and who had a CD4 count >350 cells/mm(3) was assessed. Of 458 patients included in 2006-2008 (women 70.5%; median age 37.0 years), 337 (73.6%) were classified at WHO clinical stage 3 and 121 (26.4%) at stage 4. Overall, 108 patients (23.6%) had a CD4 count >350 cells/mm(3). Of them, 94 patients (20.5%) were classified at WHO clinical stage 3, and 14 (3.1%) were classified at WHO clinical stage 4. The WHO clinical stages 3 and 4 were poorly correlated with the 'gold standard' of CD4 cell count. This study highlights the need to promote CD4 testing for assessing the patient eligibility.
