A multicentre, retrospective study of resource utilization and costs associated with glaucoma management in France and Sweden.

PURPOSE: To assess resource utilization and costs associated with glaucoma management in France and Sweden. METHODS: A total of 267 patient records (121 in France, 146 in Sweden) with diagnoses of primary open-angle glaucoma (POAG) and ocular hypertension (OH), treated medically, were reviewed for a 2-year period (beginning during 1997-99) for relevant clinical and resource utilization data. Economic data were applied to estimate treatment costs. RESULTS: The annual cost of treating glaucoma was estimated at SEK5305 (531 euro )/patient in Sweden and 390 euro/patient in France. In both countries, medication costs comprised about half of the total costs. Surgical procedures and hospitalizations represented greater proportions of total cost in France (7.0% and 9.6%, respectively) than in Sweden (3.7% and 0.6%, respectively). CONCLUSION: Medication costs represent a high proportion of total treatment costs. These findings highlight the relative importance of medical therapy and of assessing the cost-effectiveness of medications in glaucoma.

NIKE: a new clinical tool for establishing levels of indications for cataract surgery.

PURPOSE: The purpose of this study was to construct a new clinical tool for establishing levels of indications for cataract surgery, and to validate this tool. METHODS: Teams from nine eye clinics reached an agreement about the need to develop a clinical tool for setting levels of indications for cataract surgery and about the items that should be included in the tool. The tool was to be called 'NIKE' (Nationell Indikationsmodell för Kataraktextraktion). The Canadian Cataract Priority Criteria Tool served as a model for the NIKE tool, which was modified for Swedish conditions. Items included in the tool were visual acuity of both eyes, patients' perceived difficulties in day-to-day life, cataract symptoms, the ability to live independently, and medical/ophthalmic reasons for surgery. The tool was validated and tested in 343 cataract surgery patients. Validity, stability and reliability were tested and the outcome of surgery was studied in relation to the indication setting. RESULTS: Four indication groups (IGs) were suggested. The group with the greatest indications for surgery was named group 1 and that with the lowest, group 4. Validity was proved to be good. Surgery had the greatest impact on the group with the highest indications for surgery. Test-retest reliability test and interexaminer tests of indication settings showed statistically significant intraclass correlations (intraclass correlation coefficients [ICCs] 0.526 and 0.923, respectively). CONCLUSIONS: A new clinical tool for indication setting in cataract surgery is presented. This tool, the NIKE, takes into account both visual acuity and the patient's perceived problems in day-to-day life because of cataract. The tool seems to be stable and reliable and neutral towards different examiners.

[Awareness of the risk of air bag-associated injuries essential].

Restraint systems, such as air bags and seat belts with pretensioners, reduce effectively the risk of serious injuries of car occupants. However, this equipment may have some adverse effects. In a frontal air bag deployment the cushion expands with a speed of about 200 km/h towards the driver. A person within the expansion zone, i.e. within 20 centimetres from the steering wheel hub, may experience a considerable injury risk. Short people, pregnant women and people "out of normal position" are especially at risk, as well as paramedics exposed for accidentally deployed air bags during rescue work. The gas generator in the air bag produces nitrogen in a chemical process. However, small amounts of NaOH (caustic soda) may leak out of the gas generator and may contaminate eyes and wounds and cause injuries and delay healing. The air bag gases may provoke an asthmatic attack in sensible individuals and a few will experience a hearing loss, often in the range of 4,000-6,000 Hz, from the sound impulse that may reach a level of 170 dB. Correct handling, based on a familiarity of the effects and side effects of modern restraint systems, would minimise the risk of adverse effects of this safety equipment.
