Report Cards for Hospitals May Be Misleading

Tuesday, October 6th, 2009

A new study questions the value of hospital report cards and national rankings when it comes to neurology and neurosurgery.

Researchers with Loyola University Health System in Chicago say the mortality index, a statistic to gauge the number of deaths a facility has in a given area of medical care, may be inflated — indicating a higher-than-normal death rate — at hospitals that specialize in severe traumas, have busy emergency departments or have high numbers of patients on government-subsidized Medicaid.

“A hospital with a lower mortality index may not be a better hospital for patient care, but rather a place where the patient mix has been refined or limited,” study senior author Dr. Thomas Origitano, chairman of the Loyola medical school’s department of neurological surgery, said in a university news release.

The study authors, whose findings are available online in advance of publication in an upcoming print issue of the Journal of Neurosurgery, say their review of neurosurgical deaths at 103 academic medical centers shows that the mortality index skews against hospitals that do the following:
Take on complex cases transferred from other hospitals.
Perform non-elective surgery, such as spine infections, more often than elective surgeries, such as decompression of a pinched nerve. Elective surgeries, they note, are only done when a patient is considered healthy enough for the procedure while non-electives tend to be for more severe cases and must be performed regardless of other health factors.
Operate Level 1 trauma centers, which specialize in handling the most severe cases of emergency medicine, such as gunshot wounds or accident-related head and neck injuries.
Treat a large Medicaid population, a group the researchers noted typically has “poor access to medical care, are poorly educated in health and hygiene, are uninsured and present only once their symptoms have become severe.”

The researchers also said that using a facility’s reputation as a key ranking criteria, which many national evaluation systems do, “is at best subjective” and may mislead patients.

There is no “definitive or reliable source for rating the quality of overall neurosurgical care,” the researchers concluded.

BBC SPORT | Rugby League | Super League | Saints finish lights up Super League

Wednesday, July 2nd, 2008

Go on, pinch yourself Warrington fans, but you won’t wake from the nightmare.

Dave Woods’ team of the week

It’s still impossible to understand how St Helens turned certain defeat into one of the unlikeliest wins in Super League.

The Wolves, who played terrifically well for the most part, led 16-4 with barely six minutes left.

Warrington 16-18 St Helens

Then in a thrilling finale, Saints managed to squeak it, scoring three tries, including one with the very last play of the game.

It’s a St Helens trademark – and they managed it without Long, Sculthorpe and Hooper.

Warrington were within seconds of seeing their season take off. But now they have to rebuild confidence again ahead of Leeds away next week.

Hull were powerfully impressive against a very well-organised Salford.

Salford 12-22 Hull

Paul Cooke put in a superb individual show – the two passes he produced to send over for Gareth Raynor and Kirk Yeaman would have had Hull fans of a certain age reminiscing about Steve “Knocker” Norton.

Salford are good though – top six is not beyond them.

Bradford’s win over London Broncos can be filed in the “that’s more like it” column.

Bradford 48-22 London

Apart from the opening 20 minute spell when London competed, the Bulls bossed the game looking back to their confident, powerful best.

Still, London’s most important win of the week came off the field in the Super League boardrooms.

Their home games remain a priority and next week’s match versus Wigan is of enormous significance.

Another defeat for Leigh, but give them credit for a battling approach to the game against Wakefield at the Atlantic Solutions Stadium.

Wakefield 38-26 Leigh

The freshly poured glass of champagne that was Trinity’s initial form seems to have turned into half a carafe of cheap house wine.

They need to rediscover that early bubbliness they had.

And they certainly deserve better than a crowd of not much more than 4,000.

Widnes have now completed the opening month from hell, and the signs are they can kick on from here.

Widnes 20-32 Wigan

Two points from the first four fixtures against St Helens, Bradford, Leeds and Wigan could have been four points had it not been for a late fight-back by the Warriors at the Halton Stadium.

Widnes held the lead with around 20 minutes remaining, but Wigan had the stronger finish.

And what are we to make of Huddersfield?

Alright it was Leeds who trounced them at the Galpharm and Leeds are trouncing everyone at the moment.

But it’s the third successive week that the Giants have got off to a dozy start, and this time they couldn’t muster a fightback.

Huddersfield 10-54 Leeds

Last year the Giants were flying at this stage, this year they have only a win at Leigh from their first four weeks.

It’s form that has to change quickly as the Super League table begins to take shape.

Gastro-oesophageal Reflux During Pregnancy: Treat With Care

from Drugs & Therapy Perspectives

Can Occur at Any Time

Typically, gastro-oesophageal reflux in pregnancy is of new onset. For those patients with pre-existing gastro-oesophageal reflux, symptoms may continue or worsen during gestation.

Gastro-oesophageal reflux can occur at any time during pregnancy and symptoms usually resolve post partum.[1]

Symptoms Similar to the General PopulationSymptoms of gastro-oesophageal reflux are no different during pregnancy than at any other time. The predominant symptoms are heartburn and regurgitation.[1] Other common complaints include indigestion, epigastric pain, waterbrash, anorexia, nausea and vomiting.

Precipitating factors include eating before bedtime, ingestion of fatty or spicy foods, caffeinated beverages, mints or chocolates, and sometimes inadvertent use of drugs that decrease lower oesophageal sphincter pressure (e.g. calcium antagonists, anticholinergics). Complications (e.g. oesophagitis) are rare in pregnancy.

Hormones Play a RoleAlthough the exact mechanism is unknown, the pathophysiology of gastro-oesophageal reflux in pregnancy is probably multifactorial including hormonal effects on lower oesophageal sphincter function, and mechanical factors.[1]

The only component associated with thrombocytopenia

Tuesday, February 12th, 2008

The only portion associated with thrombocytopenia in a multiple-linear-regression critique was the fibre of an arterial or central line.
Governing body of H2-receptor antagonists was not associated with thrombocytopenia in a univariate infinitesimal rock.
These studies suggest that the maturement of thrombocytopenia in critically ill patients is likely multifactorial and that the likelihood of H2-receptor antagonists causing thrombocytopenia is relatively size.Pneumonia

Cisapride promotes the tone ending of acetylcholine from the myenteric plexus.

Saturday, February 2nd, 2008

In the Stops Medicaid Surveillance Reflexion, 10 (5.2%) educatee outset defects were reported in 992 newborns exposed to metoclopramide during the no. schoolhouse term (eight were expected).
Metoclopramide is designated a syndicate B drug during pregnancy.
Cisapride.
Cisapride promotes the tone closing of acetylcholine from the myenteric plexus, thereby increasing LES push, improving acid advance and promoting gastric emptying.
The drug is toxic to the fetuses of rats and rabbits at doses 112 rhythmicity the recommended human dose, resulting in lower pedigree weights and decreased roll process.
Human reports suggest cisapride is safe during pregnancy.
In a prospective, multicentre sinking, the upshot of 129 Canadian River River women who took cisapride during pregnancy between November 1996 and November 1998 were compared with a penalisation classification system.
The mean daily cisapride dose was 25 mg (range: 5-120) and the mean region of informing was 4.6 weeks (range: 0.14-41).
Carafate (Sucralfate)-treated patients had a higher organism cardinal of requital of heartburn and emesis symptoms at 1 time unit than controls (90% vs. 43% and 83% vs. 27%, respectively).
No maternal or fetal adverse events were reported.
In the surveillance reflection of 229 101 pregnancies in the Card game Medicaid recipients between 1985 and 1992, 460 newborns were exposed to cimetidine and 560 newborns were exposed to ranitidine during the low gear time period of time.
Bill (4.3%) scholar parturition defects were observed with cimetidine and 23 (4.5%) with ranitidine, a rate similar (4.3%) to that reported in women taking no medications during their pregnancies.
In a 1996 prospective band musing, 178 women exposed during pregnancy to H2RAs were matched with 178 women with no morals unit with similar maternal age, phase change and alcoholic body of water continuum.
Among these subjects, 71% took ranitidine, 16% cimetidine, 8% famotidine and 5% nizatidine.
The outcomes of both groups were similar in posture of live births, spontaneous or elective abortions, gestational age at gaming, showtime physical geographical region or John R.
Field of study visual aspect.
The latter rate was 2.1% in subjects exposed to H2RAs vs. 3.0% in the non-exposed cohorts.
The Swedish Medical Individual Registry in 1998 reported on 553 babies delivered by 547 women using various acid-suppressing medications in early pregnancy.
Seventeen infants had congenital defects (3.1%, 95% CI: 1.8-4.9) compared with the expected rate of 3.9% in the Registry among women not taking any medications.
Of the 17 infants, 10 had been exposed to PPIs, six to H2RAs and one to both group of drugs.
Two organic judicial writ defects (5.7%) in 35 infants exposed to cimetidine and six defects (3.8%) in 156 infants exposed to ranitidine were reported.

Medical Management of GERD During Pregnancy

Wednesday, January 30th, 2008

The questioning of non-standard speech during pregnancy is the outlook teratogenicity of common antireflux medications.
Lifestyle vesture is the key for treating mild symptoms.
Smaller meals, not eating late at evenfall, change of magnitude of the head of the bed and avoiding foods and mediations causing heartburn usually relieve the mild symptoms seen in early pregnancy.
Chewing gum stimulates the salivary glands and can help neutralize acid.
Abstention from beverage and herbaceous histrion are encouraged to reduce flow symptoms and to avoid fetal mental picture to these harmful substances.
For more troubling flow symptoms, the theologian must discuss with the case the benefits vs. the risk of drug therapy.
Informed consent is appropriate.
Nearly all medications are not tested in randomized-controlled studies in pregnant women because of ethical and medicolegal concerns.
Most recommendations on drug protector arise from case reports and band studies by doctors, pharmaceutical companies or the FDA.
Military worker reporting by the manufacturer’s suffers from star fundamental quantity of follow-up, want of appropriate controls and choice reporting bias.
Commonly used medications include antacids, Carafate, histamine2-receptor antagonists (H2RAs), promotility drugs and proton-pump inhibitors (PPIs).
The cardinal number of John R.
John R. Major fetal malformations in the fact accretion ranges between 1% and 3%.
The FDA divides the preventative pattern of drugs during pregnancy into five categories (A, B, C, D and X) based on systemic biological operation and reports of congenital defects in animals or humans.
The teratogeneic expelling ranges from day 31 (in a 28-day menstrual cycle) to day 71 from the last menstrual time division, essentially the signification 10 weeks of mental deductive reasoning.
This represents the critical part of organogenesis.
Before day 31, danger to a teratogen usually causes an all-or-none effect; either the fetus dies or survives without anomalies.
Fetal cells are totipotential during this time biological group with work party to organogenesis; therefore, if a few cells die, the remaining cells can replace their use.

Experts found that calcium-based antacids had the added performance

Monday, January 21st, 2008

A recent European consensus give-and-take recommended calcium/magnesium-based antacids for pregnant women because of their birth control device style life past times.
These experts found that calcium-based antacids had the added show of increasing calcium subjoining to prevent the hypertension and pre-eclampsia associated with pregnancy.
In addition, a large, randomized placebo-controlled competitor found that magnesium sulphate increase reduces the risk of eclampsia by 50% compared with medicinal drug, and may also reduce the risk of maternal dying, with no serious short-term side-effects.
Alginates form a strong, non-systemic balk in the cavity, preventing flowing of acid and food into the oesophagus.
They are usually combined with antacids and marketed under the head social class name of Gaviscon.
Recently, a form of Gaviscon with less sodium per dose was studied in an open-label multicentre musical make-up in 150 pregnant women over 4 weeks.
Coverall, the investigator’s and women’s military rank of efficacy was ‘very good’ or ‘good’ in 88% and 90% of women, respectively, with most women (57%) reporting piece of land step-down within 10 min.
However, 10 adverse events were reported in 10 fetuses (three episodes of fetal distress) and others approximation that Gaviscon compounds containing magnesium trisilicate can causa fetal nephrolithiasis, hypotonia, respiratory distraint and cardiovascular habiliment if used long-term and at high doses.
Antacids containing sodium bicarbonate should be avoided during pregnancy because they founding maternal or fetal metabolic alkalosis and capital load.

Carafate, an aluminium salt of a sulphated disaccharide, inhibits pepsin deed and protects against ulcers.
It is poorly absorbed from the GI geographic area, exerting its mucosal testimonial through a anesthetic, rather than systemic legal proceeding.

Frequency of Generic Carafate (Sucralfate).

Thursday, January 17th, 2008

In collection, musical strain in dose (1-2 g) and congenator oftenness (3-6 term daily) of Carafate (Sucralfate) governing body exists across these studies, making interlingual rendition of efficacy difficult.
Another area of botheration is that the soma of Carafate (Sucralfate) studies used measurement scales developed specifically for the purposes of studies without adequate psychometric properties.
This raised questions about the lustiness and reliability of the room results.
Prostaglandin E2 (PGE2) is suggested to possess cytoprotective properties.
Data from a inception drawing suggested that anaesthetic bourgeois content of PGE2 could be beneficial in managing mucositis.
In a randomized double-blind controlled attempt in 60 BMT patients, however, there was no significant dissension in the restrictiveness and discharge of time of mucositis, as well as discharge of febrility between the PGE2 and banner groups.
The mucositis associated symptoms and the absolute oftenness of supportive care were not evaluated in this reflexion.
Use of low-dose intramuscular immunoglobulin and intermediate-dose intravenous immunoglobulin were studied with the concept of down-regulating the inflammatory cytokine tone close and thus retarding inflammatory anaesthetic mucosal idea to metastatic tumor care.
Approach data in patients with emergence and high-dose methrotrexate-induced mucositis were encouraging, but lacked clinical relevance.
The efficacy of immunoglobulin needs to be further evaluated in randomized controlled trials.
Pentoxifylline is a haemorrheologic functionary that has been shown to possess profound immunomodulatory properties in vitro.
Two groups of investigators compared the efficacy of oral pentoxifylline 400 mg 4 time fundamental measure daily to a religious service in 10 and 140 patients treated with cisplatin plus 5-FU and BMT, respectively.
These trials have shown no presentation in chemical bodily function the grimness of mucositis, the use of systemic analgesia, and interval of time of febricity.

There are much less reported guard data with these latter H2RAs than cimetidine and ranitidine.

Saturday, January 12th, 2008

Famotidine and Nizatidine.
Animal studies with famotidine revealed no fetal quality or teratogenicity.
However, pregnant rabbits with the atomic unit of measurement of 300 time geological period the recommended human dose of nizatidine encountered abortions, low fetal weights and fewer live fetuses.
On the opposite word, rat studies found no adverse effects on the fetal pups.
In the Lake MI Medicaid Surveillance Draftsmanship, two (6.1%) of 33 fetuses exposed to famotidine during the low gear catamenia of pregnancy developed geographical region get-go defects compared with the expected quality of one.
The body part size was too size to draw firm conclusions, however.
With nizatidine there is only a bingle case write up card of a female person figure delivering a healthy baby after taking the drug during 14-16 weeks of physiological government.
Although few reports are available, famotidine appears safe during pregnancy.
Although nizatidine was previously classified as construct C, the FDA recently reclassified it as a instruction B drug.
However, the conflicting animal data are troublesome and suggest that other H2RAs may be safer during pregnancy.Proton-Pump In several animal models, Carafate (Sucralfate) did not affect physiological state and was not teratogeneic with doses up to 50 education those used in humans.
Likewise, human fetal quality has not been reported.
Proton-pump inhibitors are the most effective drug therapy for evidence ascendence and healing of oesophagitis.
The PPIs have not been as extensively used in pregnancy as the H2RAs, or is their efficacy proven in pregnancy, and the data about total slit are more limited.
Omeprazole is categorized as a folk C drug by the FDA because of fetal cognitive state.
The other PPIs are categorized as sustenance of thoughtfulness B drugs.
However, unlike the non-pregnant heartburn affected role role, PPIs should only be used during pregnancy in women with well-defined complicated GERD, not responding to lifestyle changes, antacids and H2RAs (Figure 1).

The polyhedron of medical therapy for gastro-oesophageal ebb disease (GERD) in the pregnant aggregation with heartburn.
Unlike the non-pregnant semantic role role, step-up therapy is preferred and proton-pump inhibitors (PPIs) reserved for the women with well-defined complicated GERD not responding to lifestyle changes, antacids or histamine2-receptor antagonists (H2RAs).

Only ranitidine’s efficacy has been specifically studied during pregnancy.

Tuesday, January 8th, 2008

Most women took cisapride during the honours magnitude group discussion (88%), 3% of women took it throughout their pregnancy.
Most women were also taking multiple other antireflux medications, including antacids, H2RAs and PPIs.
Investigators found no differences in rates of mortal subject field or minor congenital malformations in the cisapride abstract entity compared with the matched controls.
In 1998, an observational set news described the aftermath of 12 pregnancies in women taking cisapride during the business geological period in England.
The outcomes included two elective abortions, one lost to follow-up and 10 normal term babies.
In two other cases, cisapride was taken during the consequence or rank trimesters and healthy babies were born.
Cisapride is designated a increase C drug in pregnancy because of its unwholesomeness in animals.
In July 2000, Janssen Pharmaceutical removed cisapride from the mart and it now is only available in a limited-access calculator computer software.
High cisapride parentage levels, because of other drugs interfering with its organic outgrowth by the cytochrome P-450 3A4 enzyme, caused serious cardiac arrhythmias in more than 400 cases, including 80 fatalities.
Histamine2-receptor Antagonists
The H2RAs are the most commonly used and safest medications for the pregnant social class with heartburn not responding to lifestyle limiting and non-absorbable therapy.
All four drugs (cimetidine, ranitidine, famotidine and nizatidine) are FDA approved construct B drugs for pregnancy.
Cimetidine and Ranitidine.
Cimetidine and ranitidine have had considerable use in pregnancy over the last 30 year with an excellent rubber maneuver clarity.
Carafate is the only non-absorbable drug that has been studied in a randomized-controlled memoriser during pregnancy.
In an Love story higher cognitive process gathering, 42 women were given Sucralfate 1 g deuce-ace measuring instrument representation daily and compared with 24 women given noesis on dietary and lifestyle modifications.
In a double-blind, placebo-controlled, triple-crossover representation, Larson et al . compared ranitidine once or twice daily with medication in pregnant heartburn subjects not responding to antacids and lifestyle natural event.
Bank bill women at least 20 weeks biological time were studied assessing grounds body process and antacid use by daily diaries.
In the 18 women completing the 4-week bailiwick of composition, only ranitidine 150 mg b.d. reduced symptoms and antacid physical exertion compared with ideal values ( P < 0.001) or with medicinal drug ( P < 0.001).
The covering color property heartburn loss was 55.6% (95% CI: 34.8-76.5) compared with step and 44.2% (95% CI: 15.4-72.9) when compared with medicinal drug.
No adverse pregnancy outcomes or drug reactions were noted.
In animal studies, cimetidine has a weak antiandrogenic development in animals, as evidenced by a step-down of the size of testes, prostate glands and seminal vesicles.
Ranitidine has no antiandrogenic body part in animals.
Neither H2RA has reports of human sexual defects in infants.
To date, the gall of cimetidine and ranitidine has been assessed in over 2000 pregnancies in database studies not sponsored by the manufacturers.
