Trends in Health Care in Industrial Plants.
Cluster analysis was used to investigate trends in the provision of medical care in industrial facilities over the years. The analysis was conducted at group facilities which employed in/house physicians. Separate analyses were performed using responses from each of two occupational surveys conducted 10 years apart. The clusters resulting from each survey were then compared for differences in physician hours per employee per week and occupational injury rates per 1000 employees. Industries with high injury rates in each survey were identified. Each survey revealed four distinct clusters. As the mean number of employees increased in each cluster in each survey, the number of physician hours per week per 10,000 employees decreased. Clusters in the National Occupational Hazard Survey (NOES) survey included facilities with more employees. The mean number of physician hours per week per 10,000 employees decreased most between clusters 1 and 2 in each survey. The overall percentages of unionized facilities were similar in both surveys. A higher percentage of facilities in the NOES had arrangements with outside physicians or clinics for medical care. The percentage of facilities in the NOES with arrangements with outside physicians or clinics for medical care decreased across clusters. Mean rates of reported occupational injuries per year per 1,000 employees decreased in each cluster and in each survey. Facilities in cluster number 1 had the highest rates of occupational injuries in each survey, particularly those in the Standard Industrial Classification 35 which includes the manufacture of machinery, except electrical.
