KU activity: a method for calculating histopathologists' workloads.

An attempt to model activity of individual histopathologists or departments is illustrated, in which specimen numbers and types are weighted to produce an overall Kim unit (KU) activity. By cross referencing this numerical score against individual pathologists and clinicians, it is not only possible to interrogate departmental activity retrospectively, but also to predict and cost the impact of any change in service. The advantages over Welcans and Korner Units are illustrated.

Profiling outpatient workload: practice variations between consultant firms and hospitals in south west England.

OBJECTIVES: To describe the variation in outpatient new to old ratios between consultants and between providers for seven high volume specialties (four surgical, three medical). DESIGN: This was a descriptive study at consultant and provider unit level based upon patient administration system data from the South and West Regional Health Authority for the financial year 1992-93. Additional components of variance analysis was used to distinguish individual consultant effects from host institution effects. SETTING: The former South Western Regional Health Authority area from Gloucestershire to Cornwall. SUBJECTS: Altogether 345 consultant firms in seven specialties grouped into 13 provider unit groups. MAIN MEASURES: New to old ratio, omitting elective inpatients followed up as outpatients. RESULTS: Variation between consultants is greater in surgical than in medical specialties, while absolute levels of new to old ratios tend to be higher in surgical specialties than in medical. Variation between provider unit groups is also greater in surgical specialties. Analysis of variance shows that more total variance is attributable to provider unit group in gynaecology than in other specialties. CONCLUSIONS: Within individual specialties there is evidence of substantial variation that is not attributable to underlying differences in morbidity patterns. There is evidence of marked variation in terms of both individual consultants and institutions, a finding that provides the springboard for further analytical work. Published routine outpatient activity statistics should distinguish between new referrals, inpatient follow up, and clinic rebookings.

The role of physical workload and pain related fear in the development of low back pain in young workers: evidence from the BelCoBack Study; results after one year of follow up.

AIMS: To study the influence of work related physical and psychosocial factors and individual characteristics on the occurrence of low back pain among young and pain free workers. METHODS: The Belgian Cohort Back Study was designed as a prospective cohort study. The study population of this paper consisted of 716 young healthcare or distribution workers without low back pain lasting seven or more consecutive days during the year before inclusion. The median age was 26 years with an interquartile range between 24 and 29 years. At baseline, these workers filled in a questionnaire with physical exposures, work related psychosocial factors and individual characteristics. One year later, the occurrence of low back pain lasting seven or more consecutive days and some of its characteristics were registered by means of a questionnaire. To assess the respective role of predictors at baseline on the occurrence of low back pain in the following year, Cox regression with a constant risk period for all subjects was applied. RESULTS: After one year of follow up, 12.6% (95% CI 10.1 to 15.0) of the 716 workers had developed low back pain lasting seven or more consecutive days. An increased risk was observed for working with the trunk in a bent and twisted position for more than two hours a day (RR 2.2, 95% CI 1.2 to 4.1), inability to change posture regularly (RR 2.1, 95% CI 1.3 to 3.5), back complaints in the year before inclusion (RR 1.7, 95% CI 1.1 to 2.8), and high scores of pain related fear (RR 1.8, 95% CI 1.0 to 3.1). Work related psychosocial factors and physical factors during leisure time were not predictive. CONCLUSION: This study highlighted the importance of physical work factors and revealed the importance of high scores of pain related fear in the development of low back pain among young workers.
