Primary prevention of drink driving by the large-scale use of alcolocks in commercial vehicles.

Unlabelled: Alcolocks are commercial breath test devices that prevent a motor vehicle from starting when a driver's blood alcohol concentration (BAC) is elevated. This report is an evaluation of the experiences and BAC data from the first use of alcolocks in commercial vehicles as a primary prevention strategy. In most applications, the alcolock is imposed only after an impaired driving conviction.

Is an alcohol ignition interlock programme a useful tool for changing the alcohol and driving habits of drink-drivers?

Unlabelled: This study evaluates whether the completion of an alcohol ignition interlock programme (AIIP) results in lasting changes of the behaviour of drink drivers and whether such a programme is more effective than a conventional licence revocation followed by an approved doctor's assessment. In Sweden, DWI offenders can voluntarily select a 2-year AIIP in lieu of a 12-month licence revocation. The AIIP includes regular medical checkups designed to alter alcohol use habits.

Positive health-care effects of an alcohol ignition interlock programme among driving while impaired (DWI) offenders.

Aims: To compare the costs of hospital care and sick leave/disability pensions between two groups of driving while impaired (DWI) offenders: participants in an alcohol ignition interlock programme (AIIP) and controls with revoked licences, but with no comparable opportunity to participate in an AIIP.

Setting: As an alternative to licence revocation DWI offenders can participate in a voluntary 2-year AIIP permitting the offender to drive under strict regulations entailing regular medical check-ups. The participants are forced to alter their alcohol habits and those who cannot demonstrate sobriety are dismissed from the programme.

A Swedish alcohol ignition interlock programme for drink-drivers: effects on hospital care utilization and sick leave.

Aims: This project evaluates health outcomes following an alcohol ignition interlock programme (AIIP) by assessing hospital care utilization and sick-leave register data relative to controls with revoked licences, but with no comparable opportunity to participate in an AIIP.

Setting: In Sweden, driving while impaired (DWI) offenders can now select voluntarily a 2-year AIIP in lieu of 12 months' licence revocation. The AIIP includes regular medical check-ups designed to alter alcohol use.

An evaluation of the Swedish ignition interlock program.

The Swedish alcohol ignition interlock program for driving while intoxicated (DWI) offenders, both first-time as well as multiple offenders, was launched as a pilot project in 1999. It is a volunteer program and differs in some respects from other programs: It covers a period of 2 years, it includes very strict medical regulations entailing regular checkups by a physician, it does not require a prior period of hard suspension, and it focuses strongly on changes in alcohol habits. Records from the 5 years prior to the offence showed that DWI offenders are generally in a high-risk category long before their offense, with a four to five times higher accident rate (road accidents reported by the police) and a three to four times higher rate of hospitalization due to a road accident.

Primary and secondary prevention of drink driving by the use of alcolock device and program: Swedish experiences.

To prevent drinking and driving, alcolock (or alcohol-interlock) devices and programs were introduced in Sweden in 1999. Two types of prevention programs were begun. A primary prevention strategy was initiated to prevent alcohol impaired driving by individuals not pre-selected for having prior DWI offences.

[Only 1 out of 1 000 patients with alcohol dependence problems are reported according to the Driver's Licence Act. Physicians estimate to increase the number of reports some 70 times with a two-year ignition interlock program].

This poll, aimed at general practitioners and dependence specialists, shows that only one out of 1,000 patients diagnosed alcohol-dependent are reported to the county administrative board in accordance with the Swedish Driver's Licence Act. The anticipated negative effect on continued doctor-patient contact stands out as the predominant obstacle to filing a report. Among general practitioners an uncertainty about diagnosing alcohol dependence and alcohol abuse also was an important obstacle.

Effect of mouse submaxillary gland and NGF preparations on competent chick ectodermin vitro, studied by the immunofluorescence method.

The submaxillary gland of the male mouse, but not the female, was shown to act strongly neuralizing on competent chick ectoderm, recorded as frequency of neural antigen producing cultures. NGF preparations from mouse submaxillary gland were shown to cause a high frequency of neural antigen producing cultures. The effect of the NGF preparations diminished with time and ceased after storage at -90° C for 17 days.
