The challenge of designing a database for auditing surgical in-patients.

Surgical audit is imperative in modern practice, particularly in the developing world where resources are limited and efficient allocation important. The structure, process and outcome of surgical care can be determined for quality assurance or for research. Improved efficiency and reduction of morbidity and mortality are additional goals which may be accomplished. However, computerization, medical staff cooperation and the availability of dedicated staff are among the hurdles which may be encountered. We report the challenge of designing and establishing a database for auditing surgical inpatients in a developing country and the difficulties which were encountered.

[A nationwide survey in China on prevalence of asthma in urban children].

OBJECTIVE: Asthma is one of the most common chronic disorders in childhood. The prevalence rate of asthma and other atopic diseases have increased steadily in many countries. The present survey was conducted to find out the prevalence of childhood asthma in urban areas in China, and to assess the influence of asthma on patients' social life and their families. METHODS: A nationwide randomized survey, covering 43 cities in 31 provinces, on the prevalence of childhood asthma was carried out by the National Pediatric Cooperative Group on Asthma Research from June to October 2000, including a population of 437,873 children aged 0-14 years. Patients who had asthma, infantile asthma, cough variant asthma and questionable asthma (including asthmatic bronchitis) were chosen as subjects. RESULTS: Totally 10,065 subjects were screened out as asthma associated children by means of questionnaire to the parents, physical examination and case history review. Among them 7401 (73.53%) children, aged 3 years or more, were diagnosed as asthma of children; 1109 (11.02%) infants and young children, aged less than 3 years, as asthma of infants and young children; 785 (7.80%) as cough variant asthma; and 770 (7.65%) as questionable asthma. The prevalence of the average accumulated asthma of all the 0-14 years old asthma population (including asthma of older children and of infants) in the 31 provinces, 43 cities was 1.97%. Male/female ratio was 1.75:1. There was statistically significant difference in asthma prevalence among the 43 cities, with the highest rate in Chongqing (4.63%) and the lowest in Xining (0.25%). Overall, within China, the prevalence rate in North China was relatively lower (0.99%) and was higher in South China (1.54%), the highest was seen in eastern areas of China (2.37%), 4670 patients (70.00%) of the children had their onset before three years of age. The current 2 years prevalence of Chinese urban children was 1.54%. Thirty-six of the 43 cities had received the same kind of asthma prevalence survey 10 years ago, which made a longitudinal comparison of the two surveys available. For 6370 patients (95.47%) the family members' work was affected because of their asthma attacks. One third of the patients had used inhaler corticosteroids. In about 2/3 of patients the diagnosis of asthma was correct, while only 1/3 patients' cough variant asthma was correct compared with their early diagnosis. Sixteen percent of patients were never diagnosed to have asthmatic diseases previously. CONCLUSIONS: There has been a significantly increasing trend of asthma prevalence during the ten years, especially in the older age group. From the data of present survey it was inferred that there has been certain improvement, although not ideal, in the accuracy of diagnosis and in the practice of steroid inhalation therapy by the pediatricians in different cities.

Organ procurement expenditures and the role of financial incentives.

OBJECTIVES: To evaluate the billed charges for organ procurement and to consider the role of financial incentives to encourage organ donation. DESIGN: Observational study. Data were obtained on donor organ acquisition charges from a random sample of kidney, heart, liver, heart-lung, and pancreas transplants. SETTING: The data were based on 28.7% of all transplants performed in the United States in 1988. MAIN OUTCOME MEASURE: Total charges for donor organ acquisition. RESULTS: The median charges (1988 dollars) for donor organs were as follows: kidney, $12,290; heart, $12,578; liver, $16,281; heart-lung, $12,028; and pancreas, $15,400. Since 1983, kidney acquisition charges have increased by 12.9%, heart charges by 64.1%, and liver charges by 61.8%, after adjusting for inflation. Between 9% and 31% of total transplant procedure-specific charges were associated with donor organ acquisition. CONCLUSIONS: There is wide unexplained variation in organ procurement charges. Data on actual costs are required to establish the appropriateness of current charges. Prevailing billing and payment methods should be reevaluated in an effort to address a variety of issues related to reimbursement. Current payment methods may actually contribute to cost inefficiency. Finally, while financial incentives may enhance the efficiency of organ procurement efforts, they will adversely affect the cost-effectiveness of transplantation.

Fast acquisition of cooperation and trust: A two-stage view of trusting behavior.

Trustful behavior was defined in terms of the consecutive numbers of matching-to-sample problems worth money that each subject worked during sessions that ended in an equitable distribution. Two stages of acquisition are inherent in this definition; the first stage requires acquisition of an equitable method of distributing reinforcers (cooperation) to show that the within-session deviations (trust) from equity that develop during the second stage are temporary and are not part of an inequitable method of distributing reinforcers. Previous research has indicated that a contingency to trust is necessary to override the aversiveness of the inequity inherent in trusting and to produce consistent and maximal trust (half of the problems worked consecutively by each subject). The present experiment examined such a contingency. The trust contingency was an increased requirement for changing the direction of problem allocation. Only the subject who had been allocated a problem could change that allocation, by pulling a lever 45 or more times. On the other hand, no separate responses were required to allow the person who worked the last problem to also work the next one (passive trust). Hence, giving a problem was the only way to increase the distribution of problems to the other person and hence prevent oneself from receiving all of the reinforcers. All eight pairs of subjects cooperated from the outset. Trusting behavior developed for all four pairs exposed to the contingency to trust and expanded to maximal levels by the second session for three of the four pairs.

Clomipramine and diazepam in the treatment of agoraphobia and social phobia in general practice.

A multi-centre, double-blind trial was carried out in general practice to compare the effectiveness and tolerability of clomipramine and diazepam in patients with agoraphobia or social phobia. Patients were allocated at random to receive one or other of the trial drugs over a period of 12 weeks and dosage was adjusted to need. During the last 4 weeks daily dosage ranged from 25 to 150 mg clomipramine and from 10 to 30 mg diazepam. Analysis of results from 33 patients (15 clomipramine, 18 diazepam) showed that clomipramine was significantly superior to diazepam in improving and maintaining improvement in situational anxiety, interference in lifestyle, accompanied travel distance and total score on an agoraphobia inventory. Tolerability of clomipramine was comparable to that of diazepam.

Rectal ketamine and midazolam for premedication in pediatric dentistry.

Rectally administered midazolam (0.30 mg/kg) and ketamine (5 mg/kg) were compared for preanesthetic medication in children undergoing dental extractions. Sixty patients between the ages 2 and 9 years were randomly allocated to three groups in this double-blind study. In one group of patients who received ketamine rectally, intravenous midazolam (0.05 mg/kg) also was administered immediately after induction of anesthesia. The results from this trial show that 30 minutes after rectal administration of the two drugs, good anxiolysis, sedation, and cooperation were obtained in most patients. Although midazolam appeared to be marginally more efficacious than ketamine in the majority of assessments made and seemed to have less adverse effects, no statistically significant differences could be shown. Ketamine showed a slight decrease and midazolam a slight increase in average blood pressures after premedication. These blood pressure differences were, however, considered to be of little clinical importance.

[Application of cost-effectiveness analysis of health care interventions in developing countries. A case study in Mauritius].

OBJECTIVE: Cost-effectiveness analysis is a tool to help inform the decision maker of efficient allocation of scarce health care resources and its application has increased in developing countries during the past decade. There are, however, a variety of different approaches used to calculate cost-effectiveness ratios, given the range and the controversies surrounding the use of some components of total cost, depending on the constraints faced by various decision-making bodies. This study is an investigation of cost-effectiveness of both currently delivered and prospective health interventions in Mauritius to set priorities and assess allocative efficiency by taking into account such constraints. METHODS: Resource use and unit cost data were collected from the representative health facilities and the Ministry of Health to estimate costs of each health intervention per person. Effectiveness of each intervention was estimated from the results of the national burden of disease study and the efficacy database compiled for this exercise. Several types of cost-effectiveness were calculated for each intervention according to its characteristics and the constraints imposed by the existing infrastructures and other health interventions. RESULTS: Cost-effectiveness ratios with and without the decision maker's constraints differed significantly. Infrastructure-constrained average cost-effectiveness of thirteen currently delivered and twenty one prospective interventions ranged from $127 to $92,949 and from $77 to $66,302 per DALY averted, respectively. Incremental cost-effectiveness of the prospective interventions was from $83 to $70,553. Among the currently delivered interventions, those for perinatal disorders, mental illness, and ischemic heart disease were particularly less cost-effective than the prospective interventions. Sensitivity analysis of both effectiveness and discount rates did not change the cost-effectiveness ranking significantly. CONCLUSION: The present study showed that cost-effectiveness ratios differ significantly depending on the decision maker's constraints and that an interpretation of each cost-effectiveness study should be made with great caution when implementing its results in practice. Both average cost-effectiveness of the currently delivered interventions and incremental cost-effectiveness of the prospective interventions suggest that there is an allocative inefficiency among the currently delivered health interventions in Mauritius and a possibility of enhancing allocative efficiency through introducing alternative interventions.

Communication of bed allocation decisions in a critical care unit and accountability for reasonableness.

BACKGROUND: Communication may affect perceptions of fair process for intensive care unit bed allocation decisions through its impact on the publicity condition of accountability for reasonableness. METHODS: We performed a qualitative case study to describe participant perceptions of the communication of bed allocation decisions in an 18-bed university affiliated, medical-surgical critical care unit at Sunnybrook and Women's College Health Sciences Centre. Interviewed participants were 3 critical care physicians, 4 clinical fellows in critical care, 4 resource nurses, 4 "end-users" (physicians who commonly referred patients to the unit), and 3 members of the administrative staff. Median bed occupancy during the study period (Jan-April 2003) was 18/18; daily admissions and discharges (median) were 3. We evaluated our description using the ethical framework "accountability for reasonableness" (A4R) to identify opportunities for improvement. RESULTS: The critical care physician, resource nurse, critical care fellow and end-users (trauma team leader, surgeons, neurosurgeons, anesthesiologists) functioned independently in unofficial "parallel tracks" of bed allocation decision-making; this conflicted with the official designation of the critical care physician as the sole authority. Communication between key decision-makers was indirect and could exclude those affected by the decisions; notably, family members. Participants perceived a lack of publicity for bed allocation rationales. CONCLUSION: The publicity condition should be improved for critical care bed allocation decisions. Decision-making in the "parallel tracks" we describe might be unavoidable within usual constraints of time, urgency and demand. Formal guidelines for direct communication between key participants in such circumstances would help to improve the fairness of these decisions.

Oral versus rectal midazolam as a pre-anaesthetic sedative in children receiving dental treatment under general anaesthesia.

UNLABELLED: Dental treatment in children who are too young or too apprehensive to cooperate is often performed under sedation. In Sweden, the tradition has been to administer sedatives rectally in small children, but oral liquid sedation is now increasingly used. AIM: To compare the sedative effects of oral and rectal administration of midazolam in children undergoing dental treatment under general anaesthesia and to assess acceptance of sedative administration, acceptance of application of the facemask, and amnesia. METHODS: Fifty children aged 2-7 y were randomly allocated to receive either liquid oral or rectal sedation, with 25 children in each group. RESULTS: The sedative effect of rectal administration was higher, but not statistically significantly, than that of oral administration (p = 0.07). No significant differences in acceptance of sedative administration, acceptance of mask application or amnesia were found between the groups. CONCLUSION: Both the oral and the rectal routes can in most cases be appropriate. However, the better sedative effect of rectal administration of midazolam makes it a more favourable route in pre-cooperative and non-compliant children.
