The rate coefficients (k) for reactions of OH with acetone, methyl ethyl ketone (MEK) and dimethyl ether (DME) have been measured in the temperature range 86-112 K using a pulsed Laval nozzle apparatus. Large increases in k at lower temperatures were observed, with k(86K)/k(295K) = 334 for acetone, and k(93K)/k(295K) = 72 and 3, for MEK and DME respectively. A mechanism involving the formation of a hydrogen bonded complex prior to an overall barrier on the potential energy surface is proposed to explain this behaviour.

Prescribing by pharmacists in a collaborative manner has been occurring in the UK for several years. There are minimal studies involving pharmacist prescribing in Australia. In the present audit, 34 medication charts (17 each from the pharmacist prescriber and medical officer) were reviewed for safety and accuracy. Medication charts written by a pharmacist were more accurate than those written by a medical officer when compared to the medication history. Discrepancies and omissions had more potential for patient harm in the charts written by the medical officer. In all, 146 orders prescribed by pharmacists and 145 orders prescribed by medical officers were reviewed for safety. Of these, 90% of orders written by the pharmacist were error free, compared with 26% written by medical officers. The incorporation of pharmacist prescribers into the admissions process has the potential to improve patient safety and decrease medication errors.
