The elasticity of demand for health care in Burkina Faso: differences across age and income groups.

Like many other developing countries, Burkina Faso has been exploring how community resources can be tapped to co-finance health services. Although revenue generation is important for the viability of health services, effects on utilization and on equity of access to health care must also be considered. The authors present a logistic regression model to derive price elasticities of demand for health care based on cross-sectional survey data. While demand for health care appears inelastic overall (-0.79), subgroup analysis reveals differences in elasticity across age and income groups. Elasticities of demand for infants and children (-3.6 and -1.7) and for the lowest income quartile (-1.4) are substantially greater than overall elasticity. The method used is unusual in that it allows estimation of elasticities before the introduction of user fees. This increases the value of the information to policy makers.

The economic cost of malaria in Africa.

Although malaria is the major health problem in Africa, there is little research on its economic impact. This study adapts a framework for assessing the economic costs of illness to available data on malaria. Direct costs of illness are the costs of treatment and control activities, and indirect costs are the value of lost time due to morbidity and premature mortality. Direct costs were estimated by applying the average estimated health systems costs per case to the number of cases. Indirect costs were assessed by multiplying adult output per day times the estimated productive time lost through both adult and childhood cases. As data are not available to assess the economic impact of malaria in Africa as a whole, four case studies were performed on countries or regions for which needed data could be found. The four sites (Rwanda, Solenzo medical district of Burkina Faso, Mayo-Kebbi district, Chad, and Brazzaville, Congo) were chosen to illustrate the diversity in kinds of data which can be used (aggregate national health statistics versus household surveys) and in locations (urban versus rural). Costs were calculated for the recent past and were projected to 1995 based on recent epidemiological trends. Estimates for all sub-Saharan Africa were derived from the averages of these sites. In 1987, a case of malaria cost $9.84 (in 1987 US dollars)--$1.83 in direct costs and $ 8.01 in indirect costs. As the average value of goods and services produced per day in Africa was $0.82, this cost is equivalent to 12 days of output.(ABSTRACT TRUNCATED AT 250 WORDS)

Estimating the direct and indirect economic costs of malaria in a rural district of Burkina Faso.

Comprehensive estimates of the direct economic costs of malaria should include not only the costs of care at established health facilities, but also other expenditures, such as travel and out-of-pocket costs of drugs. They should include all episodes of illness, whether or not the patient attended a health facility. Also, the indirect economic costs, which are based on the value of time lost due to illness, consider seasonal variations in the marginal product of labor according to the agricultural season. A 1985 representative survey of 626 households in Solenzo medical district, Burkina Faso, provided household data on health service utilization, expenditures, and agricultural production with which to implement these refinements. Numbers of malaria deaths and cases were estimated by adjusting survey totals according to monthly patterns of reported malaria deaths. The marginal product of labor was valued according to typical activities in each of three agricultural seasons: brewing millet beer during the maintenance period (January-February), growing cotton during the cash crop season (March-April), and growing millet and sorghum during the food crop season (May-December). The resulting values were $0.28, $1.09, and $0.55 per day, respectively. Cost per case averaged $5.96 and cost per capita $1.15. Indirect cost due to mortality was the largest cost component ($0.79 per capita), followed by direct costs incurred by the user (e.g. transportation costs and drug purchases, $0.22 per capita). Direct costs paid by providers were small, only $0.04 per capita. A household survey provides the necessary data for more comprehensive population-based estimates of costs of malaria.

Neonatal mid-upper-arm circumference is a valid proxy for birth-weight.

A survey was carried out on a consecutive sample of 973 newborn babies representative for the city of Ouagadougou to assess the validity of neonatal mid-upper-arm-circumference (MUAC) as an indicator of birth-weight. The optimal cut-off point of neonatal MUAC to differentiate between low (less than 2500 g) and normal (greater than or equal to 2500 g) birth-weight babies was 9.5 cm. High values for sensitivity (91%) and specificity (83%) indicate an excellent validity. A newborn with a MUAC of less than 9.5 cm runs a 23 fold risk of being of low birth-weight (relative risk). The advantages of this simple, locally available and inexpensive indicator, which can be used by trained traditional birth attendants (TBA) and by the mothers themselves as a substitute for birth-weight, are discussed.

Low utilization of community health workers: results from a household interview survey in Burkina Faso.

A representative household survey was carried out in order to study the utilization of community health workers (CHW) in relation to other sources of health care. We found three main results: (1) For mild diseases, villagers consulted their CHW only in 8.8% of mild diseases, in 69% the family remained the main provider of primary care. (2) In the case of serious diseases, which the CHW was supposed to identify and refer, the villagers bypassed the CHW in 96.5%. The professional health worker were consulted directly in the majority of serious disease. (3) Sick infants were not taken to the CHW for treatment. (4) No pattern of referral between professional and CHWs could be traced. Severity of disease and perceived effectiveness of the treatment were the most important determinants of health seeking behavior. Availability, distance, and cost of travel and drugs were important service related determinants. Individual and household characteristics such as income, ethnicity, and household size were only weakly associated with choice of curative care. Reasons for the low utilization of CHWs are outlined and policy implications discussed.

Assessment of MCH services in the district of Solenzo, Burkina Faso. II. Acceptability.

Acceptability of professional MCH services in the district of Solenzo was assessed using the techniques of time and motion study combined with a user survey of attending mothers. A large proportion of mothers said to have difficulty in using the services. Three types of problems were identified and their relevance discussed: (i) wasting mothers' time through inappropriate opening hours, long waiting time in contrast with short contact time; (ii) organizational features, i.e. fragmentation of clinics offering single MCH components at different times; and (iii) staff behaviour, i.e. poor communication with users. While services do little to help mothers to utilize them, mothers were shown to receive little support in their work at home from their families while attending the clinic. Possible ways to increase acceptability of MCH care are outlined.

Assessment of MCH services in the district of Solenzo, Burkina Faso. III. Effectiveness of MCH services in detecting of and caring for mothers and children at risk.

A time and motion study was carried out in all five professional MCH-facilities in the study area. The chain of decision making process--from (i) collecting information, (ii) interpreting it as indicating risk to (iii) action--was followed while taking care not to interfere with it. At each step specific shortcomings were identified: a great number of commonly accepted risk factors was not looked for (e.g. outcome of previous pregnancies in a woman in labour). On the other hand, information indicating risk was collected, but not recognized as such (e.g. weight loss). The most striking feature of both under fives' (UFC), antenatal clinics (ANC) and maternity care was the consistent lack of any action taken as a consequence of a recognized risk factor. The possible underlying causes for the poor functioning of the risk approach in the studied peripheral services are discussed: (i) implementation failure, (ii) inappropriateness of cut-off points for risk definition leading to an unmanageably great proportion of risk clients, and (iii) a conceptual problem, i.e. the reluctance of the auxiliary staff as well as the patients to act on the basis of risk prediction, i.e. something that has not yet happened.

Assessment of MCH services offered by professional and community health workers in the district of Solenzo, Burkina Faso. I. Utilization of MCH services.

A representative household survey of a district of Burkina Faso was carried out in order to study the utilization of trained birth attendants (TBA) versus professional health workers as providers of under fives' (UFC), antenatal (ANC), and maternity care (MC). Overall utilization by the target groups varied between 13 per cent (UFC), 31 per cent (ANC), and 32 per cent (MC). The presence of a village health post did not increase utilization of MCH care. Furthermore, those who did utilize, preferred to choose another source of care: the professional midwife for ANC, the traditional 'old woman' for delivery. Sick infants were generally not taken to the village health worker (VHW), but rather treated by the family itself. The determinants of utilization were assessed by means of multivariate analysis. The level of care offered in the village (health post, dispensary, and medical centre), educational level of both the mother and the husband, and ethnic group were identified as major factors influencing health seeking behaviour in MCH. A strong case is made for improvement of quality of care before extension of geographical coverage. The importance of involving husbands in sensitization for the utilization of MCH-care is stressed and the implications are discussed for the role of the community health workers in caring for mothers and children.

On the existence of 'arrested G2 cells' in mouse epidermis.

It has been postulated that mouse epidermis contains two populations of resting cells, one of which is blocked at the G1-S boundary and the other between G2 and mitosis. The 'arrested G2 cells' were estimated, by the labelled mitosis method, to comprise 5-10% of the epidermal population and presumed to function as a 'reserve pool' which could be activated by wounding. A comprehensive search has now been carried out for arrested G2 cells in mouse epidermis using the direct methods of single cell and flow through cytophotometry. No evidence was obtained which supports the existence of such a cell compartment. Suitable control experiments were carried out to ensure that G2 cells were not lost during the isolation of epidermal nuclei.

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.

[A simple statistical method for achieving reliability in anthropometric measurements].

Most anthropometric studies fail to comment on the reliability of the measures. The authors assume that the complexity of the classical analysis of variance approach is one of the reasons for this. They therefore describe a simpler, yet scientifically sound method which assesses three sources of measurement error: intra and inter-observer as well as instrument errors. The measure of upper-arm-circumference of pregnant women, which has been proposed to be a predictor of birth-weight, is used as an example. Reliability was assessed by calculating agreement of a series of pairs of measurements. Inter and intra-observer-errors were found to be of the same size. Both types of human errors were statistically significantly greater than the error arising from the use of two different types of tapes (instrument error). It is hoped that other authors find this approach useful so that information on reliability in anthropometric studies becomes the rule rather the exception.
