A facilitated early return to work program at a large urban medical center.

An Early Return to Work Program was initiated at The Johns Hopkins Hospital and Associated Schools of Medicine, Hygiene and Nursing in Baltimore, Maryland, in April 1992 as part of a comprehensive effort to control the incidence and costs of work-related illnesses and injuries. The program was similar to others that incorporate employee and supervisory training and job accommodation, but it also included an industrial hygienist trained in ergonomics to facilitate the placement of individuals with restrictions. The return to work program was studied over a 10-year period, comparing the number of lost workday cases, lost workdays, and restricted duty days before (1989 to 1992) and after (1993 to 1999) initiation of the program. A significant decrease (55%) was observed in the rate of lost workday cases before versus after the return to work program. Furthermore, the number of lost workdays decreased from an average of 26.3 per 100 employees before, to 12.0 per 100 employees after, the return to work initiative, and the number of restricted duty days went from an average of 0.63 per 100 employees to 13.4 per 100 employees (a twentyfold increase). The study suggests that a well-structured early return to work program is an integral part of a comprehensive effort to control the duration of disability associated with occupational injuries and illness. It also indicates that to be most effective, an early return to work program must include participation by medical providers, safety professionals, injured employees, and supervisors. Our work suggests that even with these elements in place, the effectiveness of return to work programs may be increased by including an individual trained in ergonomics to facilitate the job placement process.

An ergonomics program designed to reduce the incidence of upper extremity work related musculoskeletal disorders.

In 1992, the Johns Hopkins Hospital and University initiated a program aimed at the early diagnosis and treatment of potential upper extremity work related musculoskeletal disorders (UEWMSDs), ergonomic assessment and abatement of work areas where individuals with UEWMSDs are employed, as well as the identification and correction of areas throughout the hospital and university where UEWMSDs could possibly occur. The program resulted in an initial increase in the number and cost for the treatment of UEWMSDs. Subsequently, there was a significant decrease in the number of UEWMSDs reported and virtual elimination of the need to use surgical procedures to correct these conditions. This article suggests that a coordinated program of medical care, ergonomic assessment, and intervention can be efficacious in the primary, secondary, and tertiary prevention of UEWMSD.

Repeated latex aeroallergen challenges employing a hooded exposure chamber: safety and reproducibility

Background: Bronchial, nasal, and conjunctival challenges are useful for clarifying discordant clinical history (Hx) and skin and/or serologic tests and in assessing semiquantitative changes in biologic sensitivity over time. The objective of this study was to determine the safety and reproducibility of repeated latex‐allergen challenges with a hooded exposure chamber (HEC).
