A pharmacist asked me if I could do a test for trend over time from this
table:
Year Pharm Clin
1997 400 44
1998 221 54
1999 187 69
2000 123 63
2001 74 42
2002 145 149
The table represents the number of reports of adverse events made by
pharmacists (Pharm) and by clinicians (Clin), respectively. She observes
that the number of reports declined until 2002 (there was an intervention at
the beginning of 2002), and that the proportion of reports made by
pharmacists seems to dwindle. She wants a test statistic for either of
these observations.
Do I need to -expand- by pharm and clin? Or is there an immediate test that
might work? I am having trouble seeing how to approach this.
All ideas are welcome!
Thank you,
Laurel
