The attrition rate of licensed chiropractors in California: an exploratory ecological investigation of time-trend data.

Foreman SM, Stahl MJ - Chiropr Osteopat (2010)

Bottom Line: The 10-year attrition rate rose from 10% for those graduates licensed in 1970 to a peak of 27.8% in 1991.The 10-year attrition rate has since remained between 20-25% for the doctors licensed between 1992-1998.Available evidence supports the hypothesis that the attrition rate for licensed chiropractors in the first 10 years of practice has risen in the past several decades.

ABSTRACT

Background: The authors hypothesized the attrition rate of licensed chiropractors in California has gradually increased over the past several decades. "Attrition" as determined for this study is defined as a loss of legal authority to practice chiropractic for any reason during the first 10 years after the license was issued. The percentage of license attrition after 10 years was determined for each group of graduates licensed in California each year between 1970 and 1998. The cost of tuition, the increase in the supply of licensed chiropractors and the ratio of licensed chiropractors to California residents were examined as possible influences on the rate of license attrition.

Methods: The attrition rate was determined by a retrospective analysis of license status data obtained from the California Department of Consumer Affairs. Other variables were determined from US Bureau of Census data, survey data from the American Chiropractic Association and catalogs from a US chiropractic college.

Results: The 10-year attrition rate rose from 10% for those graduates licensed in 1970 to a peak of 27.8% in 1991. The 10-year attrition rate has since remained between 20-25% for the doctors licensed between 1992-1998.

Conclusions: Available evidence supports the hypothesis that the attrition rate for licensed chiropractors in the first 10 years of practice has risen in the past several decades.

Percentage of license attrition, 1970-1998. A graphical depiction of the percentage of chiropractors without practice rights 10 years after the license was issued. The range was 10% in 1970 and a peak of 27.8% in 1991. The 10-year attrition rate has since remained between 20-25% for the doctors licensed between 1992-1998.

Figure 1: Percentage of license attrition, 1970-1998. A graphical depiction of the percentage of chiropractors without practice rights 10 years after the license was issued. The range was 10% in 1970 and a peak of 27.8% in 1991. The 10-year attrition rate has since remained between 20-25% for the doctors licensed between 1992-1998.

Mentions: The authors obtained data from the DCA database for each chiropractor licensed between January 1, 1970 and November 7, 1998 (n = 14,922). The doctors licensed during 1970 (n = 126) were grouped and sorted according to the date their license expired and was listed as other than "valid." Analysis of the group licensed during 1970 revealed 12 doctors listed as other than "valid" for an attrition rate of 10% between 1/1/70 and 12/31/79. This grouping and sorting process was repeated for those graduates licensed each year until 1998. The 10-year attrition percentage was calculated for each yearly license group and the results were plotted (Figure 1). Analysis of the DCA database revealed a higher attrition rate for those doctors licensed in the 1980s and 1990s compared to their counterparts licensed in the 1970s. Attrition after 10 years for those licensed during 1970 was 10% and this rate continued to trend upward to a peak of 27.8% by 1991, an increase of 178%. The 10-year attrition rate since 1991 has reduced from its peak but remained between 20-25% for the doctors licensed between 1992-1998.
