In 1992, a cross‐sectional questionnaire study of package truck drivers in one company was conducted at four widely scattered sites throughout the US; 317 drivers participated, representing 82% of those eligible. The package truck drivers scored significantly above the US working population comparison norm on all summary and individual scales derived from the SCL 90‐R, indicating a substantial increase in psychologic distress for this group. The Global Severity Index, the best single summary measure of psychological distress in the SCL 90‐R, revealed a mean T score for the drivers of 64.20, 91st percentile of the normative population. The group perceived significantly more daily stressful events than the average working adult, and their sensitivity to these events was also increased. Role overload, a component of the Occupational Stress Inventory, was the most consistent factor associated with symptoms of psychological distress on multiple regression analysis. This study suggests that job stress is a psychological health hazard for these drivers. Am. J. Ind. Med. 31:202–210, 1997. © Wiley‐Liss, Inc.

Purpose Rapid accessibility of (intensive) medical care can make the difference between life and death. Initial care in case of strokes is highly dependent on the location of the patient and the traffic situation for supply vehicles. In this methodologically oriented paper we want to determine the inequivalence of the risks in this respect. Methods Using GIS we calculate the driving time between Stroke Units in the district of Münster, Germany for the population distribution at day- & nighttime. Eight different speed scenarios are considered. In order to gain the highest possible spatial resolution, we disaggregate reported population counts from administrative units with respect to a variety of factors onto building level. Results The overall accessibility of urban areas is better than in less urban districts using the base scenario. In that scenario 6.5% of the population at daytime and 6.8% at nighttime cannot be reached within a 30-min limit for the first care. Assuming a worse traffic situation, which is realistic at daytime, 18.1% of the population fail the proposed limit. Conclusions In general, we reveal inequivalence of the risks in case of a stroke depending on locations and times of the day. The ability to drive at high average speeds is a crucial factor in emergency care. Further important factors are the different population distribution at day and night and the locations of health care facilities. With the increasing centralization of hospital locations, rural residents in particular will face a worse accessibility situation.
