To each according to need: a community-based approach to allocating health care resources.

OBJECTIVE: To develop a method of allocating publicly funded health care resources among communities according to their relative levels of need for health care independent of their current patterns of use. DESIGN: For each health care program population mean levels of resource allocation were calculated and were adjusted for age and sex to produce a national age- and sex-adjusted share of program resources. Indices of relative need for health care (for most programs the standardized mortality ratio) were derived from existing data on aspects of illness and death and were then used to weight the age- and sex-adjusted shares for between-community differences in health risks and health care needs. SETTING: The populations of the 49 counties in Ontario were used as the communities among which resources were allocated. Health care expenditures in 1988-89 by the Ontario Ministry of Health were used as the "budget." MAIN RESULTS: Age- and sex-adjusted resource allocations weighted for between-community differences in health care needs differed from allocations based on population size, in certain cases by up to 100%. CONCLUSION: Existing data can be used to propose allocations of health care resources that relate to relative levels of need for care across communities.     

EFFICACY OF SUCRALFATE IN PREVENTING GASTROINTESTINAL SIDE EFFECTS OF NSAIDs

To find out the efficacy of sucralfate in preventing gastrointestinal side effects of non-steroidal anti-inflammatory drugs (NSAIDs) a prospective, randomised single blind study was conducted from 1989 to 1992. Patients with osteoarthritis, rheumatoid arthritis and other long standing painful conditions, who were expected to receive NSAIDs for over three months, were recruited into the study. All medicines were discontinued for a period of 10–15 days prior to initial endoscopic assessment. NSAID therapy was started and the patients were randomised to receive either placebo (group A) or sucralfate (group B) in addition. Patient were reassessed clinically every week and an endoscopic examination was repeated after 6–8 weeks of follow-up. A total of 176 patients were studied in group A (n=91) and group B (n=85). At the end of 8 weeks gastrointestinal symptoms were present in 30.6% and 26.4% patients of group A and B respectively. Endoscopic assessment showed superficial lesions in 36.5% and 18.7% while endoscopic ulcer in 2.4% and 1.1% patients of groups A and B respectively. Thus in patients receiving chronic NSAID therapy, simultaneous administration of sucralfate reduces the incidence of superficial gastric lesions but has no significant effect on symptoms or ulcer formation.KEY WORDS: Gastropathy, Sucralfate, Nonsteroidal anti-inflammatory drugs     

The PLDD registry

The rapid acceptance of minimally invasive surgery in the United States has largely occurred without statistical proof of its superiority over traditional methods. All players in the healthcare field now see the need for valid outcome studies supporting the efficacy of new treatment techniques. Percutaneous laser disc decompression (PLDD) will gain wide acceptance only if it is statistically shown to be a safe and effective alternative treatment of a lumbar disc herniation. To that end, a central PLDD registry has been developed and implemented into clinical practice at several centers. This article reviews healthcare trends that motivated the creation of this data repository and discusses the history of its development. The currently used PLDD evaluation form is outlined and its utility is discussed. Most importantly, preliminary PLDD results and complications based on the data received are presented and analyzed.     

THE ROLE OF RAPID SLIDE CULTURE IN THE DIAGNOSIS AND MANAGEMENT OF PULMONARY TUBERCULOSIS

Rapid slide culture method using human blood medium was utilized for the primary culture of Mycobacterium tuberculosis and the results obtained were compared with results of smear examination of sputum specimens from fresh cases of pulmonary tuberculosis. Smear and rapid slide culture results of a total of 320 patients were analyzed. Slide culture was positive in 104 cases whereas smears were positive in 90 cases. Early culture confirmation in 7 days coupled with positivity better than smear examination, makes rapid slide culture a better method for diagnosis.KEY WORDS: Mycobacterium tuberculosis, Rapid slide culture, Bacteriological techniques, Colony count microbial     

Heel pain in children. Diagnosis and treatment

Heel pain in children is common, and its evaluation is challenging. Medical history and physical examination may be unrevealing owing to children's limited communication skills. Often, advanced laboratory and imaging studies are required to make an accurate diagnosis. The most common causes of heel pain in children are apophysitis, enthesopathy, and overuse syndromes such as tendinitis. Juvenile rheumatoid arthritis is relatively uncommon. In very active children, occult fractures must also be evaluated. Pain unrelated to activity may indicate tumors, infection, or congenital problems. In general, heel pain in children is treated nonoperatively. For fractures in particular, children are less likely than adults to receive surgical treatment.     

The effect of intravenous tenoxicam on pruritus in patients receiving epidural fentanyl

In this prospective randomised study, pruritus and pain were evaluated in patients undergoing abdominal surgery during which epidural fentanyl was administered. All patients had an epidural catheter inserted at the time of surgery. Epidural fentanyl 100 micrograms was administered intra-operatively and infused at a concentration of 2 micrograms.ml-1 for 48 h postoperatively. All patients received a standard anaesthetic and, in addition, the study group had a 20 mg bolus of tenoxicam intravenously, intra-operatively. Patients receiving tenoxicam demonstrated significantly lower pruritus and pain scores at 30 min, 2, 4, 8 and 24 h postoperatively as well as reduced pethidine requirements for breakthrough pain in the first 24 h. In conclusion, tenoxicam 20 mg significantly reduces the incidence and severity of postoperative pruritus in patients who received peri-operative epidural fentanyl. In addition, it significantly reduces pain and further analgesic requirements postoperatively.     

The effect of valproic acid on blood loss in patients with cerebral palsy

Valproic acid (VPA) is used in the treatment of seizure disorders often present in patients with cerebral palsy. The charts of 114 patients with cerebral palsy were reviewed to evaluate the effect of VPA on blood loss during spine surgery. Forty-one patients had seizure disorders. Of these, 18 were taking VPA as monotherapy (group III) and the remaining 23 patients were taking other antiseizure medications, including two taking VPA (group II). There was a significant increase in the number of patients with abnormal bleeding times and a significant difference (p < 0.001) in blood loss (ml/kg) in patients taking VPA as monotherapy (38.6 ml/kg vs. 30.0 ml/kg). There was also increased blood-product administration postoperatively in the VPA monotherapy patients. Physicians should be aware of this potential association between VPA use and increased blood loss. The routine laboratory tests of complete blood count, prothrombin time, and partial thromboplastin time will not adequately screen for the platelet-mediated effects of VPA.
