Quality of services and demand for health care in Nigeria: a multinomial probit estimation

This study attempts to empirically answer three important policy questions for a population sample from Ogun State, Nigeria: 1. Would price (fee) increases for health care lead to large reductions of care usage or to shifts across types of care used? 2. Would price increases lead to net increases in revenues for the health system? 3. Would the price increases have larger impacts (in the form of reductions in health care usage) on lower income members of the population? Household data are combined with data on prices and quality of care, collected directly from facilities, to estimate the demand for outpatient health care. Many of the statistical problems of demand estimation with micro level data are avoided by an innovation--the first use of the multinomial probit estimation method for health demand. A separate but related problem, that the price data used in such studies are usually endogenous (in fact usually are expenditures, which are to a great degree determined by the actual care choice) is avoided by the collection of a specific exogenous price variable directly from the health providers. Because the health care 'good'--outpatient health care--can vary to such a degree across providers, quality of care must be controlled in order that the coefficients on prices and other variables will not be biased. A strong circumstantial case can be made that past estimation efforts probably underestimated the impact of prices of care on provider choices, because those providers charging higher prices also tend to provide higher quality care and those charging lower prices to provide care of lower quality. Because of this fear of bias on the extremely important price coefficient, effective control of the quality of the care available at the alternative accessible care providers is almost certainly at this time the most important marginal innovation to demand estimation. Most past researchers simply have not had available to them exogenous quality of care information collected via a facility (provider) survey. This study tried several health care provider quality variables and finally used three distinct variables which were statistically significant: (a) expenditure per person in population served; (b) percentage of times drugs are available; and (c) interviewers evaluation of the physical condition of the facility. Price of a visit to the facility is also included, and also is an exogenous variable collected directly from the alternative available providers. For the variables of most interest for this study, price and quality of care, the results are quite reasonable and much as expected.(ABSTRACT TRUNCATED AT 250 WORDS)     

Cost sharing and the demand for ambulatory mental health services.

Asserts that the results obtained by W. G. Manning et al (see record 1985-28870-001) are premature and should not be interpreted as estimates of the effects of co-insurance on the use of mental health care because the mean dollar expenditure (MDE), an important feature of insurance plans in the Rand Corporation's Health Insurance Study (HIS), was never analyzed. It is argued that the otherwise anomalous pattern of ambulatory mental health expenditures in the HIS can be explained by the MDE effect.

Analysis of the demand for care of the asthmatic child in the emergency room

With the help of an structures observation we detect that 98% of the confined patients come from the emergency service. As a consequence of this, we proceed to go through some of the factors that bore upon the quality of the attention in that level. The medical staff non specialized subject to a survey reflect a diagnostic conviction only with the presence of sibilances. Review important fact its examine the management of the patient with a stay of some hours in the observation area in the emergency service.     

Home birth and short-stay delivery. Lessons in health care financing for providers of health care for women

The current restructuring of the U.S. health care delivery system is driven primarily by economic forces. Although primary care providers may understand the roles of technology and advocacy in fostering fundamental change, they may not be familiar with the issues related to financing of health care and, thus, may not fully appreciate the extent to which economic factors influence the character of their professional lives and the services they provide. Analysis of the loss of the home birth option in the 1950s provides a method for understanding and influencing the factors driving health care restructuring today. In examining short-stay delivery in the 1990s, this article also addresses ways in which managed health care systems may improve or restrict women's access to a variety of primary care services.     

The current state of health care in the former Soviet Union: implications for health care policy and reform

OBJECTIVE: To study planning of movement in Parkinson's disease. METHODS: The spatiotemporal pattern of movement related desynchronisation (MRD) preceding a self paced voluntary wrist flexion was compared between two groups of 10 untreated right and left hemiparkinsonian patients receiving no treatment and 10 control subjects. The MRD was computed in the 9 to 11 Hz frequency band from 11 source derivations covering the frontocentral, central, and parietocentral areas, during two successive left and right experimental conditions. RESULTS: In the two patient groups the desynchronisation appeared over the primary sensorimotor area contralateral to the affected side with a shorter latency (750 ms before movement onset for the right hemiparkinsonian group and 875 ms for the left hemiparkinsonian group) than in the control group (1750 ms), only when the movements were performed with the akinetic hand. For the non-affected hand, the same latency as in the control group was noted (1750 ms). CONCLUSION: The delay of appearance of MRD in Parkinson's disease confirmed that the programming of movement is affected, thus partially explaining akinesia.     

Delivering health and mental health care services to children in family foster care after welfare and health care reform

As the 20th century draws to a close, fundamental changes in the organization, financing, and delivery of health care and welfare services, principally directed at poor families, are likely to result in an increased number of children entering out-of-home care. These children typically have significant physical, mental health, and developmental problems. Whether the quality of health care services they receive will improve as a result of health care reform efforts and new approaches to service delivery remains to be seen. This article addresses some of the major changes wrought by welfare and health care reform and describes the essential features of a health care system that can meet the special needs of children in care.     

Preventive health care for children

This article discusses immunization, development, vision, blood pressure, dentition, behavioral, and environmental screening for preschool children. The authors then discuss screening for children in the early school years. Injury and violence prevention and topics of sexuality for the preadolescent are also presented.     

Price elasticities of demand for curative health care with control for sample selectivity on endogenous illness: an analysis for Sri Lanka

Estimation of demand for health care with samples of only the ill may bias estimates. Additionally, the lack of exogenous information, especially distance, about the alternative care providers causes omitted variable problems. This paper alleviates both problems through geographic mapping of facility information to individuals, combined with joint estimation of illness (health production) and health care demand. The joint estimation full sample demand results are compared to those from one equation estimation for only the ill sample. The results indicate that the selectivity problem is significant, but that for this sample the magnitude of the bias on the price coefficient is small.     

The quest for value in health care

Purchasers and consumers of health care will increasingly refine their definitions of "quality" and the "cost" associated with treatment. The beneficial relationship of these concepts is "value." In the new era of managed care, those providers who offer the best value will succeed. Low-value producers will fail. Understanding buyer perceptions and expectations of value will become increasingly important as markets mature and integrated systems vie for dominance.     

Integration of health care economics for addiction treatment in clinic care

Visceral pain is a substantial, clinical problem but unfortunately few experimental models are available to study this phenomenon in man. In the present study we inserted a stimulation catheter 5-10 cm into the ileo-sigmoidostomy of nine patients. The catheter contained six small, flexible electrodes separated by 4 mm. The gut was stimulated by single burst, repeated burst (five stimuli delivered at 2 Hz), or continuous burst stimuli (4 Hz for 30, 60, 90, and 120 s). The sensation (ST), pain detection (PDT), and pain tolerance (PTT) thresholds to single/repeated burst stimuli were determined. The location/size/sensitivity of referred pain after repeated/continuous stimulation were characterized. The brain potentials to single burst stimuli and to increasing stimulus intensity were measured. ST to single burst stimuli was easy to determine (8 mA) and to reproduce. The patients found it difficult to determine the PDT and PTT to single burst stimuli, however both thresholds were easily determined for repeated burst stimuli. The pain thresholds to single burst stimuli were twice as high as the thresholds to repeated burst stimuli, indicating the importance of central temporal summation for visceral pain. Minor changes in the stimulus location resulted in changes of the referred pain projection site. The words most frequently selected (78%) from the McGill Pain Questionnaire to describe repeated burst stimulations were shooting, pricking, flashing, and boring. The amplitude of the brain potentials increased at increasing stimulus intensity. A stimulus intensity giving an initial pain rating of around 5 on a 0-10 visual analog scale (VAS) was used for continuous stimulation. A general increase of the pain intensity and the area of referred pain was found during this stimulation. It was concluded that electrical stimulation of the human gut provokes pain and especially long sequences of visceral stimuli are adequate to evoke referred pain mimicking pain profiles of pathologic origin.
