Fretheim and colleagues' study confirms  yet agaiI now work for a pharmaceutical company  where the ability to change practice is a key skill. When I compare the pharmaceutical company approach to that of the health authority, there are some key differences. It is easy to deride industry’s glossy advert approach, but this is simply the tip of the communications iceberg. In addition to the glossy adverts, there is immense attention by drug companies to detail. The key evidence-based messages are tested, honed, and polished and are then delivered via several channels repetitively. The channels include face-to-face delivery by the “detailers”. Progress is tracked meticulously.This expensive but effective industry effort contrasts with the typical approach taken by the health authorities and other non-industry groups. The process of creating such guidelines has usually been so slow and difficult in the gestation that their credibility among GPs is low even before the rather dull photocopied paper is issued  and meets its predictable fate.Fretheim and colleagues say “Key components were an educational outreach visit with audit and feedback, and computerized reminders linked to the medical record system. Pharmacists conducted the visits”. This feels a bit like a policing approach (another profession watching the GP) allied to computer direction, none of which feel particularly user-friendly. A non-audit nurse (or ex-drug-rep) calling briefly but frequently using the usual pens/mugs/Post-its reminder freebies might get a better response.One study by Eve et al  did look

The distorted square-pyramidal coordination of each CuII atom is made up of four O atoms of the four fenoprofenate units and another O atom from a dimethylformamide molecule. The two enantiomeric forms of the fenoprofenate anions are present in the complex, in an optically inactive centrosymmetric arrangement.The title compound, [Cu DOI: 10.1107/S1600536808038786/bg2218Isup2.hkl            Structure factors: contains datablocks I.

The O atoms of the perchlorate anions are disordered with occupancies in the ratio 0.593 (10):0.407 (10). In the crystal, molecules are stabilized by two N—H⋯O hydrogen bonds, forming zigzag chains along the a axis, which are further interconnected by N—H⋯O hydrogen bonds and π–π interactions [centroid–centroid distance = 3.50 (1) Å] into a three-dimensional network.In the cation of the title compound, [Mn(C DOI: 10.1107/S1600536809029195/tk2501Isup2.hkl            Structure factors: contains datablocks I.

Cd⋯O secondary bonding links one of the two imidazole rings and the anion into ion pairs. The free and bound cations form layers between which the [CdCl4]2− anions are sandwiched. The CdII atom adopts a distorted trigonal-bipyramidal geometry in which the Cd⋯O bond is axial. Intermolecular N—H⋯Cl hydrogen bonds form a two-dimensional network parallel to (001) which ensures the junction between creatininium cations and [CdCl4]2− anions.In the title compound, (C DOI: 10.1107/S1600536809026944/bt2978Isup2.hkl            Structure factors: contains datablocks I.

The Zn atom is four-coordinate in a distorted tetrahedral geometry, binding to a phenolate O and an imine N atom of the Schiff base ligand, the O atom of a methanol molecule and one I− anion.

The geometry is distorted towards skew-trapezoidal-bipyramidal owing to the proximity of the double-bond S atoms [Sn—S = 2.521 (2) and Sn⋯S = 2.933 (2) Å]. The Sn atom lies on a special position of mm2 site symmetry and the tin-bound n-butyl chain is disordered about a mirror plane. The ethyl and n-butyl groups of the dithiocarbamate unit are disordered about another mirror plane.The Sn atom in the title compound, [Sn(C DOI: 10.1107/S1600536809014883/tk2428Isup2.hkl            Structure factors: contains datablocks I.
