Missouri’s unusual statewide Prescription Drug Monitoring software (PDMP) may quiet exist operational later this summer time, the state’s birthright fitness legit informed government expertise — and should no longer conflict with the continued activation of county PDMPs.
Gov. Eric Greitens waded into the statehouse debate that had blocked a statewide PDMP for approximately 12 years — making Missouri the lone ultimate state devoid of its personal software — signing government Order (EO) 17-18 on Tuesday, July 17.
The state’s PDMP is anticipated as a ally car to increasing local efforts spearheaded by using St. Louis County that total started prior this year and already cowl nearly total of the state, Dr. Randall Williams, director of fitness and senior features, instructed govt expertise.
After so decades with out a routine to comprehensively computer screen opiates in a state that has roughly 89,000 narcotics prescriptions for each one hundred,000 residents, Williams pointed out Missouri will “focus on doctor purchasers by using going to the very source of who they’re looking with” — activating its PDMP in under two months and doubtlessly serving for example to different states.
State statute forbids Missouri to directly resolve patients through the utilize of their information, Williams talked about, so the state is partnering with so-referred to as “pharmacy odds management organization” categorical Scripts protecting Co. to investigate other tips.
The pharmacy odds administration trade, he talked about, customarily handles prescriptions and prescribed drugs for insurers. amongst its obligations, a company may negotiate with the manufacturer of a reputation-manufacturer drug to gain a cheaper ordinary on behalf of an insurer.
“something that I mediate may exist a national prototype, how are you able to draw that together in five weeks, and the retort is categorical Scripts, and these prescription drug monitors [that] are already doing this in the private sector. specific Scripts is already doing this for 7 million lives in the united states,” Williams observed.
The EO’s can saturate to this point is $425,000, he talked about: $250,000 to shrink with express Scripts, and $175,000 to rent 4 unusual staffers to scrutinize information the commerce gives.
County efforts, which bask in increased to comprise round 30 counties and more than 60 percent of the state’s inhabitants, are extra concentrated towards affected person records. by contrast, the state will drudgery on choosing physicians who may well exist overprescribing and doubtlessly alerting medical boards or legislation enforcement.
“What I saw was that they are competent, through sophisticated statistics analytics, to actually in front of your eyes exhibit you the doctors, dispensers and sufferers who're of real, excessive-possibility concern for the utilize of, misusing or converting from narcotics,” Williams talked about.
He described the recognition of the probability within the records from categorical Scripts and others as a “Eureka second,” and a way to avert the time calls for and forms that a timehonored PDMP may carry with it.
The opioid calamity is “the No. 1 public fitness calamity in the united states,” the state health arm director said, “so for many of us here's knowledgeable as well as very own.”
presently neither state nor county PDMPs bask in sunset clauses after which either would expire, or statistics purge deadlines, at which point tips gathered could exist eradicated. each issues had been sticking aspects for contributors of the state Legislature.
State, commerce and aboriginal officers expressed hope and difficulty remaining week following the invoice’s passage. state Rep. Holly Rehder, R-Sikeston, added residence bill 90, which might bask in created a statewide PDMP in accordance with facts from prescribing physicians.
It ran aground in may also, but Rehder, who continues to assist efforts to cowl the state via county-level PDMPs, instructed government expertise she’s enthusiastic in regards to the governor’s EO, calling it “out-of-the-container pondering” for concentrated on so-known as “tablet mills” and medical doctors who overprescribe.
Rehder, whose members of the family bask in struggled with dependancy, additionally expressed hope that her fellow legislators may pick a quite kinder, gentler strategy to fixing the state’s drug problem.
“My hope with future legislative classes is we’ll behold greater cash toward long-term medication than penitentiary,” referred to Rehder, stating that the state of Tennessee has taken such an strategy. “lengthy-time era medication has improved effects and it’s much less lofty priced."
The Missouri state scientific affiliation (MSMA) joined other groups in may additionally in withdrawing advocate from Rehder’s invoice as amended, involved it could restrict county PDMPs if passed.
Jeff Howell, MSMA director of executive family members, told government know-how presently after the governor’s EO that his community changed into nevertheless digesting it, however said the statewide draw looks to exist more helpful to legislations enforcement than for patient treatment.
“We want to feel section of the cause to bask in a PDMP is to bask in a clinical implement that subscribers can utilize to deal sufferers,” Howell stated.
Dr. Sam page, a St. Louis County Council member who testified in January to a state Senate committee in advocate of Rehder’s bill, praised the governor for making an attempt to remedy the state’s opiate and prescription drug issue.
but page moreover advised GovTech that gaps within the EO’s insurance may additionally quiet remain, and its enforcement could bring unintended consequences.
“What you don’t wish to finish is bask in the state kicking down the door of a doctor’s workplace the region they’re caring for individuals who've cancer,” page mentioned.
Williams talked about the state hopes to shrink fantastically abruptly with two extra pharmacy improvement administration companies, conveniently blanketing the state with this category of PDMP coverage.
He described it as “complementary,” adding: “I admiration it’s two different tools attempting to glean to the identical area, and they advocate those. I’m jubilant to bound communicate to any city council it truly is on the grounds that this.”

This is section 1 of a two-part train on Oracle XML capabilities in Oracle Database 11gR2. In section 1, McCormick introduces the reader to XML capabilities in Oracle Database and sets up a scenario where a commerce wants to draw XML documents into its database. section 2 details how that XML data can then exist used and queried to gain commerce information.
The utilize of XML data continues to extend across enterprises, and databases will play a role in XML data management. Yet many Oracle database professionals bask in been reluctant to adopt Oracle XML capabilities into their management practices.
That should change with Oracle Database 11gR2. Oracle XML features in the newest version of its database product compose it easier to introduce XML into your data management practices with minimal disruption to SQL applications. In this data integration utilize case, they will demonstrate relational access of XML data while pointing out unusual Oracle Database 11gR2 improvements along the way.
Relational access of XML data from Oracle Database 11gR2
XML data integration, which has become increasingly more common in IT shops, is relatively simple to implement in the database. It is quiet timehonored to find XML documents shredded into relational tables for SQL application access. Shredding is expensive, time consuming and oftentimes unnecessary. A better approach may exist to liquidate the shredding step by directly ingesting the XML data into the database and placing relational views over the XML structures.
The following fictitious example demonstrates the utilize of aboriginal Oracle XML database capabilities supporting relational access of XML data.
The ABC Gum Company’s data integration hub receives source system purchase orders as XML documents, as shown below. The company is looking for a simple solution within Oracle Database to accept well-formed XML documents and present them relationally. Its SQL-based hub maintenance application can then perform data manipulation operations prior to the data being published to downstream XML applications, archived and eventually purged.
'<?xml version="1.0"?><PurchaseOrder><OrderNumber>11111</OrderNumber><OrderDate>2010-01-15</OrderDate><CustomerName>Joe Smith</CustomerName><User>JSMIT</User><SpecialInstructions>Air Mail</SpecialInstructions><LineItems><LineItem ItemNumber="1"><Description>Bubble Gum</Description><Part Id="7155" UnitPrice="19.95" Quantity="2"/></LineItem><LineItem ItemNumber="2"><Description>Blow Pops</Description><Part Id="3742" UnitPrice="15.95" Quantity="2"/></LineItem></LineItems></PurchaseOrder>'
Notice the XML document contains a LineItem collection (repeating elements) analogous to a master-detail model.
Create XML table, relational view and indexes
We’ll originate by creating a solitary schema-less XML table to store their tangled purchase order structure.Notice the table is created as an XML type data type. You can moreover create a table with an XML type column. So far so good, as we’ve already simplified a multi-table relational data model to a solitary physical table.
create table abc_purchase_order of xmltype(constraint abc_purchase_order_pk primary key (order_number))xmltype store as securefile binary xml(compress high)virtual columns(order_number as (xmlcast(xmlquery('/PurchaseOrder/OrderNumber' passing object_value returning content) as number (5))),order_date as (xmlcast(xmlquery('/PurchaseOrder/OrderDate' passing object_value returning content) as date)))partition by range (order_date)(partition yr_2010 values less than(to_date('01/01/2011','mm/dd/yyyy')),partition yr_2011 values less than (to_date('01/01/2012','mm/dd/yyyy')));
Notable Oracle XML 11gR2 enhancements comprise the utilize of SECUREFILE for large object (LOB) storage, binary XML type storage and partitioning. SECUREFILE is preferred over BASICFILE for LOB storage for several reasons: de-duplication, compression, encryption, caching, logging and piecewise updates. Binary XML type storage (persistence) is a post-parsed format providing flexibility, storage optimization and performance improvement. Partitioning, enabled by virtual columns, provides manageability, availability and advocate for information lifecycle management (ILM).
Next, we’ll expose their purchase order relationally for SQL access by creating a relational view over the XML data structure. Here is where views provide and shroud the translation from XML data structures (i.e., elements) to relational constructs (i.e., columns) allowing SQL applications to read XML data.
create view abc_po_master_detail_view asselect m.order_number, m.order_date, m.customer_name, m.userid, m.special_instructions, d.*from abc_purchase_order po,xmltable('/PurchaseOrder' passing po.object_valuecolumnsorder_number number(5) path 'OrderNumber',order_date date path 'OrderDate',customer_name varchar2(30) path 'CustomerName',userid varchar2(10) path 'User',special_instructions varchar2(80) path 'SpecialInstructions',lineitem xmltype path 'LineItems/LineItem') m,xmltable('LineItem' passing m.lineitemcolumnsitemno number(10) path '@ItemNumber',description varchar2(25) path 'Description',partno varchar2(14) path 'Part/@Id',quantity number(12,2) path 'Part/@Quantity',unitprice number(8,4) path 'Part/@UnitPrice') d;
Then we’ll add structured and unstructured indexes on commonly queried portions of their XML document to provide increased performance. unusual to Oracle 11gR2, structured XMLIndex components utilize relational content tables (relational index structures) to organize structured XML content. For non-partitioned tables, defining a XMLIndex index to comprise total fields in a relational view will ensure that a query result of a relational view query will compass entirely from the underlying XMLIndex content table, theoretically achieving relational performance. Additionally, touchstone relational secondary indexes can exist created on the columns of the structured index effectively indexing the index for even faster performance.

There are a number of ways that you can identify blocking that is occurring in your SQL instance. You can Run the undocumented sp_who2 stored procedure but that will only give you the session that is being blocked. You could download the excellent sp_whoisactive, written by Adam Machanic, which will give you the session_id and the SQL script that is causing the blocking. However both of these methods will only expose you blocking sessions when you Run it (obviously). If you want to capture historical blocking information then another routine is needed. If you suspect that blocking is occurring in your system, the best way to capture the information is to utilize Extended Events.
In order to finish this, first enable the blocked process report:-
EXEC sp_configure 'Show Advanced Options', 1
EXEC sp_configure 'blocked process threshold (s)', 1
EXEC sp_configure 'Show Advanced Options', 0
N.B. – I’ve set the threshold circumscribe here to one second. Depending on your environment you may wish to change it.
Then create an extended event to capture the information from the report:-
CREATE EVENT SESSION [BlockedProcesses] ON SERVER
ADD EVENT sqlserver.blocked_process_report
ADD TARGET package0.event_file(SET filename=N'C:\SQLServer\XEvents\BlockedProcesses\BlockedProcesses.xel',max_file_size=(128))
N.B. – Don’t forget to change the file path.
Then start the session:-
ALTER EVENT SESSION [BlockedProcesses] ON SERVER
state = START;
Now that the session is running you can query it:-
[XML DATA] AS [Raw XML],
[XML Data].value('(/event[@name=''blocked_process_report'']/@timestamp)','DATETIME') AS [TimeStamp],
[XML Data].value('(/event/data[@name=''database_name'']/value)','SYSNAME') AS [Database Name],
[XML Data].value('(/event/action[@name=''username'']/value)','SYSNAME') AS [Username],
[XML Data].value('(/event/data[@name=''transaction_id'']/value)','BIGINT') AS [Transaction ID],
[XML Data].value('(/event/data[@name=''lock_mode'']/text)','SYSNAME') AS [Lock Mode],
[XML Data].value('(/event/data[@name=''duration'']/value)','BIGINT')/1024 AS [Duration (ms)],
[XML Data].value('(/event/data[@name=''blocked_process'']/value/blocked-process-report/blocked-process/process/inputbuf)','SYSNAME') AS [Blocked Query],
[XML Data].value('(/event/data[@name=''blocked_process'']/value/blocked-process-report/blocked-process/process/@waitresource)','SYSNAME') AS [Wait Resource],
[XML Data].value('(/event/data[@name=''blocked_process'']/value/blocked-process-report/blocking-process/process/inputbuf)','SYSNAME') AS [Blocking Query]
(SELECT OBJECT_NAME AS [Event],
CONVERT(XML, event_data) AS [XML Data]
sys.fn_xe_file_target_read_file('C:\SQLServer\XEvents\BlockedProcesses\BlockedProcesses*.xel',NULL,NULL,NULL)) AS v
ORDER BY [XML Data].value('(/event[@name=''blocked_process_report'']/@timestamp)','DATETIME') DESC
EDIT:- It’s been pointed out in the comments by Jason that the value for username will recrudesce as NULL because no action was defined for this value in the CREATE EVENT script. Adding the following piece of code will allow the username to exist returned:-
ADD EVENT sqlserver.blocked_process_report(Action (sqlserver.Username))
This piece of code will output the time of the block, the blocked query, the blocking query, the duration of the obscure and the resource that the blocked query is waiting on. I’ll Run through a quick example now to expose what information is retrieved when a obscure is recorded. So first I’ll create a demo database with one table (I bask in already Run the setup scripts above):-
CREATE DATABASE [BlockingExample];
CREATE TABLE dbo.[BlockedTable]
(RecordID INT IDENTITY(1,1) PRIMARY KEY,
INSERT INTO dbo.BlockedTable
Then I’ll open two sessions, the first will exist an update in a transaction that I’ll leave open (my blocker):-
SET ColA = 'BlockingTEST1';
The second will exist a simple SELECT against the table (my blocked query):-
SELECT * FROM dbo.BlockedTable;
I’ll Run this for a while, cancel it and relegate the first query. Then I queried the extended event, here’s the results:- As you can see, The SELECT is showing up as the blocked query and the update as the blocker. But we’ve moreover got the resource the SELECT is waiting on:- KEY: 14:72057594039042048 (8194443284a0) Using this information they can identify the exact row in the table. The 14 is the database_id:-
SELECT cognomen from sys.databases WHERE database_id = 14
This gives the cognomen of the test database “BlockingExample”. Next 72057594039042048 is the hobt_id of the table, they can glean the table cognomen by running:-
FROM sys.objects o
INNER unite sys.partitions p ON o.object_id = p.object_id
WHERE p.hobt_id = 72057594039042048
This outputs the cognomen of the test table “Blocked Table”. Finally they can utilize (8194443284a0) to identify the exact row in the table by running:-
WHERE %%LOCKRES%% = '(8194443284a0)'
This will output the test record that was inserted and then locked by the UPDATE statement. A very contrived example, I know, but it does expose how verbose Extended Events are when capturing blocking. Not only can they identity the blocker and blockee but the exact record that the blockee was waiting on.
