Can morbidity be inferred from prescription drug use? Results from a nation-wide prison population study.
To estimate psychiatric and somatic morbidity in a nation-wide prison population, as inferred from detailed medication sheets. ⋯ This study has demonstrated high psychiatric and somatic morbidity in a nation-wide population of prison inmates receiving adequate health services. As the morbidity estimates are inferred from prescription drug use they must be interpreted with caution. However, we do believe that our study, utilizing this unconventional but readily available source of information, has yielded valuable knowledge regarding the physical and mental health of a nation-wide prison population.

Mortality in the USA has been shown to spike on Christmas and New Year's Day. No comparable analyses are available for European data despite recognised seasonal mortality variations. ⋯ No disturbance of trend was seen at Easter. The causes of the 'holiday phenomenon' are not understood, but absence of a Christmas spike in NNT may indicate that it is preventable.
