27.3.2 Interfaces<br />

Interfaces connect the central database to other <strong>in</strong>formation systems and to users<br />

(<strong>in</strong>clud<strong>in</strong>g patients). Selection of pharmacy <strong>in</strong>formation systems may be based <strong>in</strong><br />

part on the <strong>in</strong>terfaces that are provided or that are possible (that may be negotiated<br />

with a vendor). Interfaces may provide:<br />

Physical access to pharmacy <strong>in</strong>formation for users<br />

� <strong>Computer</strong> workstations (onl<strong>in</strong>e access to drug libraries, handbooks)<br />

� Telephone (direct consultation with an on-site pharmacist <strong>in</strong> the case of<br />

standalone databases)<br />

� Mobile devices (handheld/wireless)<br />

Pr<strong>in</strong>t media (handbooks, brochures)<br />

Functional tools to help users locate <strong>in</strong>formation<br />

� Search eng<strong>in</strong>es<br />

� Calculators for doses, body surface area<br />

� Reference charts to normal values<br />

Integration with cl<strong>in</strong>ical <strong>in</strong>formation and workflows<br />

� Electronic medical records<br />

� <strong>Computer</strong>ized provider order entry<br />

� Electronic medication adm<strong>in</strong>istration records<br />

Interoperability with external <strong>in</strong>formation systems<br />

� F<strong>in</strong>ancial <strong>in</strong>formation systems<br />

� Benefits <strong>in</strong>formation systems<br />

� Commercially available data dictionaries<br />

Specific configurations for <strong>in</strong>terfaces between a PharmIS and CPOE <strong>in</strong>clude:<br />

complete <strong>in</strong>tegration of the two systems, a bidirectional <strong>in</strong>terface, a unidirectional<br />

<strong>in</strong>terface or not us<strong>in</strong>g an <strong>in</strong>terface. Each has advantages and disadvantages and<br />

these should be considered carefully when decid<strong>in</strong>g on a system. 2<br />

27.3.3 Cl<strong>in</strong>ical Decision Support<br />

Cl<strong>in</strong>ical decision support (CDS) provides “cl<strong>in</strong>icians, patients or <strong>in</strong>dividuals with<br />

knowledge and person-specific or population <strong>in</strong>formation, <strong>in</strong>telligently filtered or<br />

presented at appropriate times, to foster better health processes, better <strong>in</strong>dividual<br />

patient care.” 5 Functionalities of PharmIS CDS <strong>in</strong>clude:<br />

Check<strong>in</strong>g doses based on allowed dose ranges<br />

Detect<strong>in</strong>g known allergy and drug <strong>in</strong>teractions<br />

Identify<strong>in</strong>g and flagg<strong>in</strong>g duplicate orders/therapies<br />

Provid<strong>in</strong>g patient and drug-specific warn<strong>in</strong>gs<br />

Intercept<strong>in</strong>g drug <strong>in</strong>compatibilities (<strong>in</strong>travenous admixtures)
