IMS or WK (now Symphony) buy and package the data for Pharma. Some Pharma/biotech sell direct to SP's most cases however, SP acquire product from wholesaler. Biggest issue straight away is a Pharma company that buys only Symphony data, not IMS- and in a certain geography there is a SP that gets a huge amount of business from some big providers and they only report to IMS, not Symphony. If that's the case, better beg your company to either buy both or swap to IMS. Symphony was crying about a monopoly that IMS had, yet at same time was having issues - telling SP's they couldn't handle their additional business ans took them an incredibly long time. Even then, when an SP just starts to report to either, there is a period of time typically a month and a half, when the data stream is sent to IMS/Symphony but all the bugs are getting ironed out etc before it's officially accepted and then reported to Pharma. One of the requirements is a minimum number of scripts sent in that time period- so if a tiny pharmacy, might not even have enough business to get accepted.
Other issue obv is the standard.. MD swears they are Rxing your product, ask the SP rep, perhaps md is just telling you what you want to hear. Some provide insight to Pharma reps, others don't bc providers ask them not to, some just don't want to give out info on the doc and have the doc get pissed when the rep runs back and tells the provider that they are not actually writing their product per the SP rep.
Even if a certain SP gets "all" of the business from a certain office, depending on the disease state and that SP's contracts, they can actually only fill anywhere from @35-70% of what they receive.
There are also many, small SP's, or start up pharmacies that call themselves SP's or dabble a bit, that simply do not report at all.
Ask office what SP's they send to. Then contact the local rep and ask if their pharmacy reports, to whom they report, and how often- some weekly, some monthly, some just once a quarter.
