Prevalence Thresholds

In a comment on my prevalence day post it was suggested that I could publish exactly what the cut off levels were for each area in each country. These are simply 5% of the maximum prevalence in each area. Always happy to oblige - and the table is below for 2005/6.

(if you have no idea what I am talking about it might be worth reading the original article first)

	England	N. Ireland	Scotland	Wales
STROKE	1.19%	0.3%	0.25%	0.56%
LVD	0.27%	0.09%	0.17%	0.18%
CHD	1.43%	0.43%	0.57%	1.14%
BP	2.51%	1.1%	1.36%	2.85%
DM	0.81%	0.31%	0.38%	0.96%
COPD	0.87%	0.33%	0.39%	0.63%
EPILEPSY	0.23%	0.09%	0.14%	0.18%
THYROID	0.8%	0.28%	0.79%	1.56%
CANCER	0.16%	0.08%	0.12%	0.35%
MH	1.77%	0.19%	0.27%	0.21%
ASTHMA	1.07%	0.59%	0.69%	1.95%

Also interesting is the number of practices that fell beneath the threshold in each area. What is particularly interesting in that the seems almost exclusively English problem. Being so much larger than the other countries an 'outlier' practice is more likely. In the smallest country - Northern Ireland - there are virtually no practices below the threshold at all. The number in the table are the proportion of practices below the threshold who will be rounded up.

	England	N. Ireland	Scotland	Wales
STROKE	34%	0%	2%	6%
LVD	29%	5%	7%	9%
CHD	5%	0%	1%	6%
BP	1%	0%	0%	6%
DM	1%	0%	1%	6%
COPD	27%	1%	3%	9%
EPILEPSY	3%	0%	5%	6%
THYROID	5%	0%	1%	9%
CANCER	4%	1%	5%	11%
MH	97%	3%	16%	13%
ASTHMA	0%	0%	1%	5%
