Diagnostic quality in rural health centres in Burkina Faso

Assessing Prescribing Practice in Church-Owned Primary Healthcare (PHC) Institutions Intanzania: A Pilot Study

A retrospective survey of prescribing patterns in 10 church-owned primary healthcare (PHC) institutions in Dar es Salaam region, Tanzania, was carried out by trained research assistants in order to assess the prescribing practices of healthcare providers in these institutions. From a total of 15 000 prescriptions, 600 were recorded randomly from patient registers retrospectively. This work was carried out between April to September 1996. Each prescription was recorded using World Health Organization Action Programme on Essential Drugs (WHO/DAP) forms and analysed manually. The average number of drugs per prescription was 2.9; the percentage encounters for injections and antibiotics was 38 and 71, respectively. Ninety-four per cent of all drugs were prescribed according to the essential drug list of Tanzania.

Therapeutic itineraries: the medical field in rural Burkina Faso

The health care system in Burkina Faso presents a paradox. The number of health centres in the rural areas has increased significantly since the signing of the Alma-Ata Declaration in 1978. However, studies show that these public health facilities are grossly under-utilized. Parallel to this development, local healers of different types are numerous and popular, and self-treatment extremely common. The present study explores this paradox on the basis of fieldwork in three villages in south-east Burkina Faso. Drawing on Bourdieu's notions of field and capital, the local health care system is analysed as a medical field where the different types of healers and health care institutions position themselves and are positioned through villagers' choice of therapy in their health seeking processes. The popularity of self-medication and various types of local healers are discussed in relation to the strengths of the various forms of capital in the medical field. It is argued that both local social relationships and indigenous knowledge are important variables in this particular area and add to our understanding of the low utilization rate of the public health facilities.

Health worker preferences for performance-based payment schemes in a rural health district in Burkina Faso

BACKGROUND

One promising way to improve the motivation of healthcare providers and the quality of healthcare services is performance-based incentives (PBIs) also referred as performance-based financing. Our study aims to explore healthcare providers' preferences for an incentive scheme based on local resources, which aimed at improving the quality of maternal and child health care in the Nouna Health District.

DESIGN

A qualitative and quantitative survey was carried out in 2010 involving 94 healthcare providers within 34 health facilities. In addition, in-depth interviews involving a total of 33 key informants were conducted at health facility levels.

RESULTS

Overall, 85% of health workers were in favour of an incentive scheme based on the health district's own financial resources (95% CI: [71.91; 88.08]). Most health workers (95 and 96%) expressed a preference for financial incentives (95% CI: [66.64; 85.36]) and team-based incentives (95% CI: [67.78; 86.22]), respectively. The suggested performance indicators were those linked to antenatal care services, prevention of mother-to-child human immunodeficiency virus transmission, neonatal care, and immunization.

CONCLUSIONS

The early involvement of health workers and other stakeholders in designing an incentive scheme proved to be valuable. It ensured their effective participation in the process and overall acceptance of the scheme at the end. This study is an important contribution towards the designing of effective PBI schemes.

Direct observation of outpatient management of malaria in a rural Ghanaian district

INTRODUCTION

In Ghana, malaria continues to top outpatient morbidities; accounting for about 40% of all attendances. Effective case-management is key to its control. We evaluated case-management practices of uncomplicated malaria in Kwahu South District (KSD) health facilities to determine their conformity to guidelines.

METHODS

We conducted a cross sectional survey at all public health facilities in three randomly selected sub-districts in KSD. A non-participatory observation of suspected malaria consultations was conducted. Suspected malaria was defined as any person with fever (by history or measured axillary temperature > or equal 37.5 oC) presenting at the selected health facilities between 19th and 29th April 2013. Findings were expressed as frequencies, relative frequencies, mean (± standard deviation) and median.

RESULTS

Of 70 clinical observations involving 10 prescribers in six health facilities, 40 (57.1%) were females and 16 (22.9%) were below five years. Median age was 18 years (interquartile range: 5-33). Overall, 63 (90.0%) suspected case-patients had diagnostic tests. Two (3.6%) were treated presumptively. All 31 confirmed and 10 (33.3%) of the test negative case-patients received Artemisinin-based Combination Therapies (ACTs). However, only 12 (27.9%) of the 43 case-patients treated with ACT received Artesunate-Amodiaquine (AA). Only three (18.8%) of the under-fives were examined for non-malarial causes of fever. Mean number of drugs per patient was 3.7 drugs (± 1.1). Only 45 (64.3%) patients received at least one counseling message.

CONCLUSION

Conformity of malaria case-management practices to guidelines in KSD was suboptimal. Apart from high rate of diagnostic testing and ACT use, prescription of AA, physical examination and counseling needed improvement.

Does enrollment status in community-based insurance lead to poorer quality of care? Evidence from Burkina Faso

INTRODUCTION

In 2004, a community-based health insurance (CBI) scheme was introduced in Nouna health district, Burkina Faso, with the objective of improving financial access to high quality health services. We investigate the role of CBI enrollment in the quality of care provided at primary-care facilities in Nouna district, and measure differences in objective and perceived quality of care and patient satisfaction between enrolled and non-enrolled populations who visit the facilities.

METHODS

We interviewed a systematic random sample of 398 patients after their visit to one of the thirteen primary-care facilities contracted with the scheme; 34% (n = 135) of the patients were currently enrolled in the CBI scheme. We assessed objective quality of care as consultation, diagnostic and counselling tasks performed by providers during outpatient visits, perceived quality of care as patient evaluations of the structures and processes of service delivery, and overall patient satisfaction. Two-sample t-tests were performed for group comparison and ordinal logistic regression (OLR) analysis was used to estimate the association between CBI enrollment and overall patient satisfaction.

RESULTS

Objective quality of care evaluations show that CBI enrollees received substantially less comprehensive care for outpatient services than non-enrollees. In contrast, CBI enrollment was positively associated with overall patient satisfaction (aOR = 1.51, p = 0.014), controlling for potential confounders such as patient socio-economic status, illness symptoms, history of illness and characteristics of care received.

CONCLUSIONS

CBI patients perceived better quality of care, while objectively receiving worse quality of care, compared to patients who were not enrolled in CBI. Systematic differences in quality of care expectations between CBI enrollees and non-enrollees may explain this finding. One factor influencing quality of care may be the type of provider payment used by the CBI scheme, which has been identified as a leading factor in reducing provider motivation to deliver high quality care to CBI enrollees in previous studies. Based on this study, it is unlikely that perceived quality of care and patient satisfaction explain the low CBI enrollment rates in this community.

Assessment of providers' referral decisions in rural Burkina Faso: a retrospective analysis of medical records

BACKGROUND

A well-functioning referral system is fundamental to primary health care delivery. Understanding the providers' referral decision-making process becomes critical. This study's aim was to assess the correctness of diagnoses and appropriateness of the providers' referral decisions from health centers (HCs) to district hospitals (DHs) among patients with severe malaria and pneumonia.

METHODS

A record review of twelve months of consultations was conducted covering eight randomly selected HCs to identify severe malaria (SM) cases among children under five and pneumonia cases among adults. The correctness of the diagnosis and appropriateness of providers' referral decisions were determined using the National Clinical Guidebook as a 'gold standard'.

RESULTS

Among the 457 SM cases affecting children under five, only 66 cases (14.4%) were correctly diagnosed and of those 66 correctly diagnosed cases, 40 cases (60.6%) received an appropriate referral decision from their providers. Within these 66 correctly diagnosed SM cases, only 60.6% were appropriately referred. Among the adult pneumonia cases, 5.9% (79/1331) of the diagnoses were correctly diagnosed; however, the appropriateness rate of the provider's referral decision was 98.7% (78/79). There was only one case that should not have been referred but was referred.

CONCLUSIONS

The adherence to the National Guidelines among the health center providers when making a diagnosis was low for both severe malaria cases and pneumonia cases. The appropriateness of the referral decisions was particularly poor for children with severe malaria. Health center providers need to be better trained in the diagnostic process and in disease management in order to improve the performance of the referral system in rural Burkina Faso.

"Workhood"-a useful concept for the analysis of health workers' resources? An evaluation from Tanzania

BACKGROUND

International debates on improving health system performance and quality of care are strongly coined by systems thinking. There is a surprising lack of attention to the human (worker) elements. Although the central role of health workers within the health system has increasingly been acknowledged, there are hardly studies that analyze performance and quality of care from an individual perspective. Drawing on livelihood studies in health and sociological theory of capitals, this study develops and evaluates the new concept of workhood. As an analytical device the concept aims at understanding health workers' capacities to access resources (human, financial, physical, social, cultural and symbolic capital) and transfer them to the community from an individual perspective.

METHODS

Case studies were conducted in four Reproductive-and-Child-Health (RCH) clinics in the Kilombero Valley, south-eastern Tanzania, using different qualitative methods such as participant observation, informal discussions and in-depth interviews to explore the relevance of the different types of workhood resources for effective health service delivery. Health workers' ability to access these resources were investigated and factors facilitating or constraining access identified.

RESULTS

The study showed that lack of physical, human, cultural and financial capital constrained health workers' capacity to act. In particular, weak health infrastructure and health system failures led to the lack of sufficient drug and supply stocks and chronic staff shortages at the health facilities. However, health workers' capacity to mobilize social, cultural and symbolic capital played a significant role in their ability to overcome work related problems. Professional and non-professional social relationships were activated in order to access drug stocks and other supplies, transport and knowledge.

CONCLUSIONS

By evaluating the workhood concept this study highlights the importance of understanding health worker performance by looking at their resources and capacities. Rather than blaming health workers for health system failures, applying a strength-based approach offers new insights into health workers' capacities and identifies entry points for target actions.

Can lay community health workers be trained to use diagnostics to distinguish and treat malaria and pneumonia in children? Lessons from rural Uganda

OBJECTIVE

To determine the competence of community health workers (CHWs) to correctly assess, classify and treat malaria and pneumonia among under-five children after training.

METHODS

Consultations of 182 under-fives by 14 CHWs in Iganga district, Uganda, were observed using standardised checklists. Each CHW saw 13 febrile children. Two paediatricians observed CHWs' assessment, classification and prescription of treatment, while a laboratory scientist assessed CHW use of malaria rapid diagnostic tests (RDTs). The validity of CHWs' use of RDTs to detect malaria and respiratory timers to diagnose pneumonia was estimated using a laboratory scientist's RDT repeat reading and a paediatrician's repeat count of the respiratory rate, respectively.

RESULTS

From the 182 consultations, overall CHWs' performance was adequate in taking history (97%), use (following procedures prior to reading result) of timers (96%) and use of RDTs (96%), but inadequate in classification (87%). Breath readings (classified as fast or normal) were 85% in agreement with the paediatrician (κ = 0.665, P < 0.001). All RDT readings were in agreement with those obtained by the laboratory scientist. Ninety-six per cent (85/89) of children with a positive RDT were prescribed an antimalarial drug, 40% (4/10) with fast breathing (gold standard) were prescribed an antibiotic and 91% (48/53) with both were prescribed both medicines.

CONCLUSION

Community health workers can be trained to use RDTs and timers to assess and manage malaria and pneumonia in children. We recommend integration of these diagnostics into community case management of fever. CHWs require enhanced practice in counting respiratory rates and simple job aides to enable them make a classification without thinking deeply about several assessment results.

Community Effectiveness of Artemisinin-Based Combination Therapy for Malaria in Rural Southwestern Nigeria

A descriptive cross sectional survey using an interviewer-administered questionnaire was carried out among 700 caregivers whose children had fever during the previous two weeks. The aim was to determine the community effectiveness of malaria treatment using arthemeter-lumefantrine (AL) among under-5-year-olds in a rural community in southwestern Nigeria. A total of 353 (50.9%) children received AL. About half of these children (49%) were said to have been treated within 24 hours of onset of symptoms; 44% took the drug for the stipulated period of time; 42% received the correct dosage; and only 4% received all the treatment steps. With a drug efficacy of 100%, AL achieved a community effectiveness of 4%. The greatest effort in the home management of malaria strategy should be in reducing delay in treatment and improving dosage and duration of treatment.

Expanding access to primary care without additional budgets? A case study from Burkina Faso

The aim of this study is to demonstrate the impact of increased access to primary care on provider costs in the rural health district of Nouna, Burkina Faso. This study question is crucial for health care planning in this district, as other research work shows that the population has a higher need for health care services. From a public health perspective, an increase of utilisation of first-line health facilities would be necessary. However, the governmental budget that is needed to finance improved access was not known. The study is based on data of 2004 of a comprehensive provider cost information system. This database provides us with the actual costs of each primary health care facility (Centre de Santé et de Promotion Sociale, CSPS) in the health district. We determine the fixed and variable costs of each institution and calculate the average cost per service unit rendered in 2004. Based on the cost structure of each CSPS, we calculate the total costs if the demand for health care services increased. We conclude that the total provider costs of primary care (and therefore the governmental budget) would hardly rise if the coverage of the population were increased. This is mainly due to the fact that the highest variable costs are drugs, which are fully paid for by the customers (Bamako Initiative). The majority of other costs are fixed. Consequently, health care reforms that improve access to health care institutions must not fear dramatically increasing the costs of health care services.

The differences in characteristics between health-care users and non-users: implication for introducing community-based health insurance in Burkina Faso

The purposes of this study are to describe the characteristics of different health-care users, to explain such characteristics using a health demand model and to estimate the price-related probability change for different types of health care in order to provide policy guidance for the introduction of community-based health insurance (CBI) in Burkina Faso. Data were collected from a household survey using a two stage cluster sampling approach. Household interviews were carried out during April and May 2003. In the interviewed 7,939 individuals in 988 households, there were 558 people reported one or more illness episodes; two-thirds of these people did not seek professional care. Health care non-users display lower household income and expenditure, older age and lower perceived severity of disease. The main reason for choosing no-care and self-care was 'not enough money'. Multinomial logistic regression confirms these observations. Higher household cash-income, higher perceived severity of disease and acute disease significantly increased the probability of using western care. Older age and higher price-cash income ratio significantly increased the probability of no-care or self-care. If CBI were introduced the probability of using western care would increase by 4.33% and the probability of using self-care would reduce by 3.98%. The price-related probability change of using western care for lower income people is higher than for higher income although the quantity changed is relatively small. In conclusion, the introduction of CBI might increase the use of medical services, especially for the poor. Co-payment for the rich might be necessary. Premium adjusted for income or subsidies for the poor can be considered in order to absorb a greater number of poor households into CBI and further improve equity in terms of enrollment. However, the role of CBI in Burkina Faso is rather limited: it might only increase utilisation of western health care by a probability of 4%.

Assessing health worker performance in malaria case management of underfives at health facilities in a rural Tanzanian district

OBJECTIVE

To study the quality of malaria case management of underfives at health facilities in a rural district, 2 years after the Tanzanian malaria treatment policy change in 2001.

METHODS

Consultations of 117 sick underfives by 12 health workers at 8 health facilities in Mkuranga District, Tanzania were observed using checklists for history taking, counselling and prescription. Diagnoses and treatment were recorded. Exit interviews were performed with all mothers/guardians and blood samples taken from the underfives for the detection of malaria parasites and antimalarial drugs. Quality of care was measured using indicators adopted from the integrated management of childhood illnesses multi-country evaluation.

RESULTS

Quality of care measured by indicator scores averaged 31% of what was considered optimal. The poorest results were for history taking. Nevertheless, 89% of febrile children were treated with antimalarials, in line with national guidelines for fever treatment. Of these, 61% had a parasitaemia > or =2000/microl. There was no difference in treatment given to those with parasitological malaria compared with those without parasites. Pre-treatment levels of chloroquine and sulphadoxine/pyrimethamine were low and detected in 2% and 13%, respectively.

CONCLUSION

Although most febrile children were given antimalarial treatment, quality of care in terms of history taking and counselling was sub-optimal. Despite this, the study community had changed behaviour from self-treatment to seeking care at health facilities. This is encouraging for introduction of artemisinin-based combination therapies policies as one could focus resources into improving care at health facilities and still reach out with treatment to most febrile children.

Quality of interaction between primary health-care providers and patients with type 2 diabetes in Muscat, Oman: an observational study

Background

A good patient-physician interaction is particularly important in chronic diseases like diabetes. There are so far no published data regarding the interaction between the primary health-care providers and patients with type 2 diabetes in Oman, where diabetes is a major and growing health problem. This study aimed at exploring how health-care providers interact with patients with type 2 diabetes at primary health-care level in Muscat, Oman, focusing on the consultation environment, and some aspects of care and information.

Methods

Direct observations of 90 consultations between 23 doctors and 13 diabetes nurses concerned with diabetes management during their consultations with type 2 diabetes patients in six primary health-care centres in the Muscat region, using checklists developed from the National Diabetes Guidelines. Consultations were assessed as optimal if more than 75% of observed aspects were fulfilled and sub-optimal if less than 50% were fulfilled.

Results

Overall 52% of the doctors' consultations were not optimal. Some important aspects for a positive consultation environment were fulfilled in only about half of the doctors' consultations: ensuring privacy of consultation (49%), eye contact (49%), good attention (52%), encouraging asking questions (47%), and emphasizing on the patients' understanding of the provided information (52%). The doctors enquired about adverse effects of anti-diabetes drugs in less than 10% of consultations. The quality of the nurses' consultations was sub-optimal in about 75% of 85 consultations regarding aspects of consultation environment, care and information.

Conclusion

The performance of the primary health-care doctors and diabetes nurses needs to be improved. The role of the diabetes nurses and the teamwork should be enhanced. We suggest a multidisciplinary team approach, training and education to the providers to upgrade their skills regarding communication and care. Barriers to compliance with the guidelines need to be further explored. Improving the work situation mainly for the diabetes nurses and further improvement in the organizational efficiency of diabetes services such as lowering the number of patients in diabetes clinic, are suggested.

Home and community management of acute respiratory infections in children in eight Ugandan districts

BACKGROUND

Acute respiratory infections (ARI), especially pneumonia, are the second largest child killer in sub-Saharan Africa. Symptoms, including cough and difficult/rapid breathing, frequently overlap those of malaria. In Uganda, the Home-Based Management (HBM) strategy treats all childhood fevers as malaria in the community, ignoring the pneumonia symptom overlap.

AIM

To determine the extent of overlap of fever and ARI symptoms at community level, the timeliness of care-seeking and the treatments sought for ARI with or without fever.

METHODS

From eight districts, 3223 households with 3249 children aged <2 years were randomly selected through two-stage cluster sampling and their primary caretakers were interviewed regarding the child's most recent illness episode using 2-week recall.

RESULTS

Of the 1682 children <2 years who had been sick, 19% reported overlapping symptoms of fever, cough and "difficult/rapid breathing". Of these, 45% were given antimalarials alone. Use of health facilities was low and 42% of antibiotics used were obtained from drug shops or home-stocks.

CONCLUSIONS

Given the large overlap of fever and ARI symptoms and the reported practice of using primarily antimalarials, the implications of HBM might be the continued or increased mismanagement of pneumonia. Community drug distributors' ability to identify rapid breathing and make a presumptive diagnosis of pneumonia based on respiratory rate should be tested.

Inequality in willingness-to-pay for community-based health insurance

The purpose was to provide information for devising community-based health insurance (CBI) policies that reduce inequality in enrolment and further inequality in access to health services. A two-stage cluster sampling was used in the household survey. Inequalities in willingness-to-pay (WTP) for CBI are examined by expenditure quintile using data collected from a household survey. Interviews were conducted with 2414 individuals, 705 of whom were household heads. A bidding game method was used to elicit WTP. Individuals and households were assigned to 6-month expenditure quintiles. We found that mean and median individual WTP for CBI was significantly higher for higher spending quintiles, as was mean and median household WTP. The curves of cumulative percentage of individual and household WTP shifted rightwards for higher quintiles, implying that at any given premium the lower the quintile the lower the uptake of CBI. The Gini coefficient for individual WTP and household WTP was 0.15 and 0.08, respectively, and for individual 6-month expenditure and household 6-month expenditure is 0.68 and 0.63, respectively. The results imply that the premium needs to be adjusted for income; otherwise, a lower proportion of poor people will enrol in CBI and without exemptions or subsidies the poor will have less access to health services than the rich. Thus, exemptions and subsidies for the poor for enrolling in CBI are an important issue for decision-makers with an objective of improving equity of health and helping the poor to break out of the cycle of poverty. Since the distribution of WTP by household is less unequal than the distribution of WTP by individuals, the household might be a better unit of enrolment in terms of equity than the individual.

The feasibility of community-based health insurance in Burkina Faso

To ensure the acceptability of community-based insurance (CBI) by the community and its sustainability, a feasibility study of CBI was conducted in Burkina Faso, including preference for benefit package of CBI, costing of health services, costing of the benefit package and willingness-to-pay (WTP) for the package. Qualitative methods were used to collect information about preferences for the benefit package. Cost per unit health services, health demand obtained from household survey and physician-judged health needs were used to estimate the cost of the benefit package. The bidding game method was used to elicit household head's WTP for the package. We found that there were strong preferences for inclusion of high-cost healthservices such as operation, essential drugs and consultation fees in the benefit package. It is estimated that the cost of the package per capita was 1673 CFA (demand-based) and 9630 CFA (need-based), including 58% government subsidies (euro 1 = 655 CFA). The average household head with eight household members agreed to pay from 7500 (median) to 9769 CFA (mean) to join the CBI for his/her household. The WTP results were influenced by household characteristics, such as location, household size and age composition. Under certain assumptions (household as the enrolment unit, median household head's WTP as premium for the average household, 50% enrolment rate), it would be feasible to run CBI in Nouna, Burkina Faso if enrolees' health demand did not increase by more than 28% or if the underwriting of the initial losses was covered by extra funds.

Willingness-to-pay for community-based insurance in Burkina Faso

PURPOSE

To study the willingness-to-pay (WTP) for a proposed community-based health insurance (CBI) scheme in order to provide information about the relationship between the premium that is required to cover the costs of the scheme and expected insurance enrollment levels. In addition, factors that influence WTP were to be identified.

METHODS

Data were collected from a household survey using a two-stage cluster sampling approach, with each household having the same probability of being selected. Interviews were conducted with 2414 individuals and 705 household heads. The take-it-or-leave-it (TIOLI) and the bidding game were used to elicit WTP.

RESULTS

The average individual was willing to pay 2384 (elicited by the TIOLI) or 3191 (elicited by the bidding game) CFA (3.17 US dollars or 4.25 US dollars) to join CBI for him/herself. The head of household agreed to pay from 6448 (elicited by the TIOLI) or 9769 (elicited by the bidding game) CFA (8.6 US dollars or 13.03 US dollars) to join the health insurance scheme for his/her household. These results were influenced by household and individual ability-to-pay, household and individual characteristics, such as age, sex and education. The two methods yielded similar patterns of estimated WTP, in that higher WTP was obtained for higher income level, higher previous medical expenditure, higher education, younger people and males. A starting point bias was found in the case of the bidding game.

CONCLUSIONS

Both TIOLI and bidding game methods can elicit a value of WTP for CBI. The value elicited by the bidding game is higher than by the TIOLI, but the two approaches yielded similar patterns of estimated WTP. WTP information can be used for setting insurance premium. When setting the premiums, it is important to consider differences between the real market and the theoretical one, and between the WTP and the cost of benefits package. The beneficiaries of CBI should be enrolled at the level of households or villages in order to protect vulnerable groups such as women, elders and the poor.

Case management of malaria in under-fives at primary health care facilities in a Tanzanian district

OBJECTIVE

To study case management of malaria in children under 5 years of age at primary health care facilities in Kibaha district, Tanzania and to evaluate the accuracy of self-reported mothers'/guardians' information on chloroquine use in children.

METHOD

A random sample of 652 mothers/guardians with sick children under 5 years of age attending 10 primary health care facilities was observed and interviewed. Blood samples for determination of chloroquine levels were taken from all children and thick smears for detection of malaria parasites were taken from the children who were prescribed chloroquine. Information on diagnoses and prescriptions was collected from recording books.

RESULTS

Fever and respiratory problems were the most common complaints and accounted for 75% and 46% of the presenting conditions, respectively (some complained of both). Fifty-four per cent of the children received medication at home, most commonly antipyretics and chloroquine, 20% had been taken to another health facility and 3% to traditional healers before coming to the health facilities. There was a significantly higher use of antipyretics among home treated children compared with those taken previously to health facilities (P <or= 0.001). Use of antibiotics was higher among children who had been taken to health facilities previously (P < 0.0001). Nine per cent had received injections. The average consultation time was 3.8 min. Thirty-nine per cent of the children were physically examined, with large interfacility variations. In 71% of the children malaria was diagnosed, either as a single condition or in combination with others, and with respiratory problems as the leading overlapping condition (29%). Malaria parasites were found in 38% of the cases given a malaria diagnosis. A total of 81% of the health facility prescriptions included analgesics, 71% chloroquine and 54% antibiotics. A fourth of all prescriptions were injections. The proportions of chloroquine and antibiotic injections in relation to the total number of prescriptions varied between the facilities. Of the 529 blood samples successfully analysed for chloroquine, 98% had detectable blood drug levels. Ninety-seven per cent of the children without history of prior chloroquine treatment had detectable drug levels in the blood, 11% had high levels (>or= 1000 nmol/l). Of those prescribed chloroquine, 16% already had high blood concentrations of the drug.

CONCLUSION

Health care services, i.e. presumptive malaria diagnosis, consultation time and procedure for physical examination need to be improved.

Prescription practices of public and private health care providers in Attock District of Pakistan

The irrational use of drugs is a major problem of present day medical practice and its consequences include the development of resistance to antibiotics, ineffective treatment, adverse effects and an economic burden on the patient and society. A study from Attock District of Pakistan assessed this problem in the formal allopathic health sector and compared prescribing practices of health care providers in the public and private sector. WHO recommended drug use indicators were used to study prescription practices. Prescriptions were collected from 60 public and 48 private health facilities. The mean (+/- SE) number of drugs per prescription was 4.1 +/- 0.06 for private and 2.7 +/- 0.04 for public providers (p < 0.0001). General practitioners (GPs) who represent the private sector prescribed at least one antibiotic in 62% of prescriptions compared with 54% for public sector providers. Over 48% of GP prescriptions had at least one injectable drug compared with 22.0% by public providers (p < 0.0001). Thirteen percent of GP prescriptions had two or more injections. More than 11% of GP prescriptions had an intravenous infusion compared with 1% for public providers (p < 0.001). GPs prescribed three or more oral drugs in 70% of prescriptions compared with 44% for public providers (p < 0.0001). Prescription practices were analysed for four health problems, acute respiratory infection (ARI), childhood diarrhoea (CD), fever in children and fever in adults. For these disorders, both groups prescribed antibiotics generously, however, GPs prescribed them more frequently in ARI, CD and fever in children (p < 0.01). GPs prescribed steroids more frequently, however, it was significantly higher in ARI cases (p < 0.001). For all the four health problems studied, GPs prescribed injections more frequently than public providers (p < 0.001). In CD cases GPs prescribed oral rehydration salt (ORS) less frequently (33.3%) than public providers (57.7%). GPs prescribed intravenous infusion in 12.3% cases of fever in adults compared with none by public providers (p < 0.001). A combination of non-regulatory and regulatory interventions, directed at providers as well as consumers, would need to be implemented to improve prescription practices of health care providers. Regulation alone would be ineffective unless it is supported by a well-established institutional mechanism which ensures effective implementation. The Federal Ministry of Health and the Provincial Departments of Health have to play a critical role in this respect, while the role of the Pakistan Medical Association in self-regulation of prescription practices can not be overemphasized. Improper prescription practices will not improve without consumer targeted interventions that educate and empower communities regarding the hazards of inappropriate drug use.

Comprehensive community effectiveness of health care. A study of malaria treatment in children and adults in rural Burkina Faso

Malaria is one of the most important causes of morbidity and mortality in children in sub-Saharan Africa, yet community effectiveness of treatment is not well understood. This study presents a quantitative estimate of community effectiveness of malaria treatment in Burkina Faso, based on population surveys, observational studies of health services and user surveys. Analysis of seven steps in the process of treating malaria reveal the following: (1) 21% of people with malaria attend health centres; (2) 31% of them have a sufficient history taken; (3) 69% receive a complete clinical examination; (4) 81% receive the correct dosage of drugs prescribed; (5) 91% purchase the drugs; (6) 68% take the drugs as prescribed; (7) the drugs are estimated to be 85% effective. Taking all the steps into account, overall community effectiveness is estimated to be 3%. Statistically significant differences in age and gender are seen in some steps. Quinine is prescribed too frequently. Critical issues in educating health care workers include complete history-taking and clinical examination, rational indication for quinine and adjusted drug dosages for children. We identify utilization and diagnostic quality as offering the greatest potential for improvement in overall community effectiveness.

Rapid risk household screening by neonatal arm circumference: results from a cohort study in rural Burkina Faso

Neonatal arm circumference (NAC) and other attributes of the newborn and its household were analysed as potential predictors of child death in a cohort of 1367 newborn children representing the majority of births in a rural area of Burkina Faso from 1992 to 1994. During 3872 person years observed 264 children died, resulting in an average mortality rate of 6.8% per year. 90 mm was chosen as the best cut-off to differentiate low NAC associated with high mortality from normal NAC. The hazard ratio of children with low NAC (15.7%) compared to others was 1.7 (P < 0.001) in Cox regression. Kaplan-Meier curves of cumulative survival showed that this higher risk lasted throughout the first two years of life. Multivariate Cox regression comparing NAC with other variables known or suspected to influence child survival yielded a model including mother's death, twin birth, affiliation to a particular health centre, home delivery and birth during the rainy or harvest season as other significant risk factors beside NAC. Protective factors were mother's participation in antenatal care despite considerable distance to the health centre, medium household size (5-7 members) and household cash crop production. We propose a simple risk score for rapid household screening in rural Burkina Faso and comparable settings elsewhere for identifying households at risk of experiencing child death. As much of the other variables' contribution to the explanation of survival pattern is absorbed by NAC in more parsimonious models, even simpler screening strategies based on NAC make sense. In the study area risk households will be offered periodical home visits by the local nurse promoting immunization, treatment of illness and strengthening the mothers' competence to recognize and manage frequent health problems of their children as part of a 'Shared Care' concept.
