Effect of project-based experiential learning on the health service delivery indicators: a quasi-experiment study

Background

Kenya’s new constitution passed in 2010 recognizes the right of quality care resulting in the devolution of health service delivery to the sub-national units called counties in 2013. However, the health system performance continues to be poor. The main identified challenge is poor health systems leadership. Evidence shows that addressing health system leadership challenges using different leadership intervention models has the potential to improve health outcomes. The purpose of this study is to report findings on the effect of project-based experiential learning on the health service delivery indicators addressed by 15 health management teams from 13 counties in Kenya, as compared to the non-trained managers.

Methods

A quasi-experimental design without a random sample was used to evaluate the effectiveness of the leadership program. The health managers from the 13 Counties and 15 health facilities had previously undergone a 9-month leadership training, complimented with facility-based team coaching based on 15 priority institutional service improvement projects at the Strathmore University Business School. Pre-test and post-test data were collected in three-point periods (beginning, end of the training, and 24-to-60 months post-training). The control group comprised 14 other health institutions within the same counties.

Results

Leadership training and coaching built around priority institutional health service improvement projects in the intervention institutions showed: a) skilled birth attendance increased, on average, by 71%; b) full immunization of children, increased by 52%; c) utilization of in and out-patient services, which on average, increased by 90%; d) out-patient turn-around time reduced on average by 65% and; e) quality and customer satisfaction increased by 38.8% (in all the intervention facilities). These improvements were sustained for 60 months after the leadership training. In contrast, there were minimal improvements in service delivery indicators in the comparison institution over the same period of time. Ninety-three percent of the respondents attributed team-coaching built around priority institutional health service improvement projects as a key enabler to their success.

Conclusions

The study provides support that an intervention underpinned by challenge driven learning and team coaching can improve a range of health service delivery outcome variables.

Preclinical drug evaluation system in the Plasmodium knowlesi baboon model of malaria: the methotrexate study

BACKGROUND

Drug resistance against first-line antimalarials warrants search for new lead compounds and repurposing of drugs such as methotrexate. Animal models are required for preclinical drug development before clinical testing. This study aimed to develop a preclinical drug development system in baboons infected with Plasmodium knowlesi.

METHODS

Protocols for drug administration, pharmacokinetics, clinical chemistry and haematology were developed in the baboon model. Baboons were infected with P. knowlesi and methotrexate administered orally for 5 days. Clinical signs, parasitaemia, gross and histopathology examinations were conducted to determine effect of methotrexate in baboons.

RESULTS

No major clinical chemistry, haematology and pathological changes attributable to methotrexate were observed. Parasitaemia suppression of 77.67% was achieved at a methotrexate dose of 3.0 mg/kg.

CONCLUSIONS

A protocol for preclinical drug development in the baboon was optimized. Methotrexate suppressed P. knowlesi malaria in baboons. These findings warrant further characterization of methotrexate for use in combination therapy.

Characterisation of metabolic acidosis in Kenyan children admitted to hospital for acute non-surgical conditions

Metabolic acidosis is associated with most severe malaria deaths in African children, and most deaths occur before maximum antimalarial action is achieved. Thus, specific acidosis treatment may reduce mortality. However, the underlying mechanisms remain poorly understood and no specific interventions have been developed. A detailed characterisation of this acidosis is critical in treatment development. We used the traditional and Stewart's approach to characterise acidosis in consecutive paediatric admissions for malaria and other acute non-surgical conditions to Kilifi District Hospital in Kenya. The overall acidosis prevalence was 21%. Gastroenteritis had the highest prevalence (61%). Both the mean albumin-corrected anion gap and the strong ion gap were high (>13 mmol/l and >0 mmol/l, respectively) in malaria, gastroenteritis, lower respiratory tract infection and malnutrition. Presence of salicylate in plasma was not associated with acidosis but was associated with signs of severe illness (odds ratio 2.11, 95% CI 1.1-4.2). In malaria, mean (95% CI) strong ion gap was 15 (14-7) mmol/l, and lactate, creatinine and inorganic phosphorous explained only approximately 40% of the variability in base excess (adjusted R2 = 0.397). Acidosis may be more common than previously recognised amongst paediatric admissions in Africa and is characterised by the presence of currently unidentified strong anions. In malaria, lactate and ketones, but not salicylate, are associated with acidosis. However, unidentified anions may be more important.

A randomised, controlled trial of once daily and multi-dose daily gentamicin in young Kenyan infants

AIMS

To test the suitability of a simple once daily (OD) gentamicin regimen for use in young infants where routine therapeutic drug monitoring is not possible.

METHODS

In an open, randomised, controlled trial, infants with suspected severe sepsis admitted to a Kenyan, rural district hospital received a novel, OD gentamicin regimen or routine multi-dose (MD) regimens.

RESULTS

A total of 297 infants (over 40% < or =7 days) were randomised per protocol; 292 contributed at least some data for analysis of pharmacological endpoints. One hour after the first dose, 5% (7/136) and 28% (35/123) of infants in OD and MD arms respectively had plasma gentamicin concentrations <4 microg/ml (a surrogate of treatment inadequacy). Geometric mean gentamicin concentrations at this time were 9.0 microg/ml (95% CI 8.3 to 9.9) and 4.7 microg/ml (95% CI 4.2 to 5.3) respectively. By the fourth day, pre-dose concentrations > or =2 microg/ml (a surrogate of potential treatment toxicity) were found in 6% (5/89) and 24% (21/86) of infants respectively. Mortality was similar in both groups and clinically insignificant, although potential gentamicin induced renal toxicity was observed in <2% infants.

CONCLUSIONS

A "two, four, six, eight" OD gentamicin regime, appropriate for premature infants and those in the first days and weeks of life, seems a suitable, safe prescribing guide in resource poor settings.

Chloroquine is not a risk factor for seizures in childhood cerebral malaria

OBJECTIVES

There are a number of case reports in the medical literature suggesting an association between the ingestion of chloroquine and subsequent seizure activity. Our study was designed to investigate the relationship between blood levels of chloroquine (CQ), its metabolite desethylchloroquine (DCQ), and seizures in children admitted to hospital with cerebral malaria.

METHODS

Serial blood levels of CQ and DCQ were measured over the first 24 h of hospital admission in children with cerebral malaria. The number and duration of all seizures was recorded, and statistical analysis subsequently performed to determine the relationship between seizure activity and blood concentrations of CQ and DCQ.

RESULTS

Chloroquine was detected in 92% (100/109) of admission blood samples. 54% (59/109) of the patients had one or more seizures after admission, while 8% (9/109) had an episode of status epilepticus. Median (interquartile range) baseline concentrations of CQ and DCQ were, respectively, 169.4 microg/ml (75.1-374.9) and 352.3 microg/ml (81.9-580.1) for those children who had seizures after admission, compared to CQ 227.5 microg/ml (79.4-430.2) and DCQ 364.0 microg/ml (131.3-709.4) for those who did not have seizures (P > 0.5 for all comparisons). Baseline concentrations of CQ and DCQ were not significantly associated with the occurrence of seizures lasting for 5 min or more. The nine children who had an episode of status epilepticus had significantly lower median admission levels of CQ than those without status epilepticus: 75.1 microg/l (7.4-116.5) vs. 227.5 microg/l (85.6-441.2), P = 0.02. Multivariate logistic regression analysis, taking into account factors likely to affect the risk of seizures in hospital, failed to change the significance of these results.

CONCLUSIONS

These findings suggest that chloroquine does not play an important role in the aetiology of seizures in childhood cerebral malaria.

Medical Research: Are we doing enough in Africa?

As we look forward to the end of this Century and the beginning of the next, our politicians are busy telling us about their plans to turn our countries into New Industrialised Nations (NINS) by the year 2010 (or is it 2020?). Most of us dismiss this as mere political rhetoric. But as medical researchers, perhaps we ought to look at this 2020 business more carefully. Let us assume that a few African countries will indeed become New Industrialised Nations by the year 2020. Shall we, as medical researchers, have contributed to this industrialisation process through our research efforts? Perhaps to answer this question one needs to look at the state of medical research in most African countries at the moment. In the majority of our countries, research output in the form of publications in reputable medical journals has fallen in recent years. Perhaps the only exception is research on AIDS/HIV, but only because of external funding and/or collaboration with other centres outside Africa. In addition, most of the prominent African medical scientists trained in the sixties and seventies have either retired or will soon retire. What they have left or will soon leave behind are institutions which are so run down due to lack of resources that proper research and training no longer takes place. The tragedy of all this is that Africa is not producing enough well trained young medical scientists to continue with the good work started by those retiring now. Some countries in South East Asia have become New Industrialised Nations through aggressive training programmes and incentives for their young scientists (including medical scientists). Can African medical scientists be optimistic about the year 2020, given the meagre resources we are operating with at the present time? I am not.

Infection with Plasmodium berghei alters benzodiazepine receptor in rat brain

The purpose of this study was to assess the effect of malaria infection on benzodiazepine binding in rat brain. Young male Wistar rats were infected with the rodent parasite Plasmodium berghei, while age-matched control rats (n = 5) received normal saline intraperitoneally. Parasitemia was determined in blood of infected animals. Animals were killed after two weeks, and synaptosomal brain membrane homogenate was prepared from cerebral cortex. Membrane homogenate was incubated in duplicate with 3H-flunitrazepam (0.2-10 nM in buffer, pH 7.4) and binding parameters determined. The number of receptors (Bmax) was decreased marginally but significantly (P = 0.047) in malaria-infected (MI) rats (MI rats: 1.12 +/- 0.1 pmol.mg-1 protein; control rats: 1.42 +/- 0.08 pmol.mg-1 protein) while binding affinity (Kd) was not altered (MI rats: 1.18 +/- 0.3 nM; control rats: 1.02 +/- 0.15 nM). These results suggest that malaria may be associated with decreased benzodiazepine activity.

Halofantrine pharmacokinetics in Kenyan children with non-severe and severe malaria

1. Kenyan children with uncomplicated malaria given oral halofantrine (HF; non-micronised suspension; 8 mg base kg-1 body weight 6 hourly for three doses) showed wide variation in the disposition of HF and desbutylhalofantrine (HFm). 2. Eight Kenyan children with severe (prostrate) falciparum malaria who were receiving intravenous quinine, were given the same HF regimen by nasogastric tube. One patient had undetectable HF and two had undetectable HFm at all times after drug administration. 3. The mean AUC(0,24 h) of HF in prostrate children was half (7.54 compared with 13.10 micrograms ml-1 h) (P = 0.06), and that for HFm one-third (0.84 compared with 2.51 micrograms ml-1 h) (P < 0.05) of the value in children with uncomplicated malaria. 4. Oral HF may be appropriate for some cases of uncomplicated falciparum malaria in Africa, but in patients with severe malaria, the bioavailability of HF and HFm may be inadequate.
