- Services and programs organized around a particular
diagnosis, disease, need, or age group
2. Overall infection prevention
- Hospital commitment to reducing infection risk
(tracking infections, immunization reporting, etc.)
3. Commitment to best practices
- Includes participating in conferences, safety procedure
guidelines, database tracking, etc.
4. Success in reducing ICU infections
- Rates of infection in ICUs

Findings:
1. Termination rates higher after Magnet Status
2. After Magnet Status more experienced nurses leaving more often
3. Overall termination decreases with experience, especially Involuntary termination
Nurses’ Turnover Trends, Cont.Nurses’ Turnover Trends, Cont.
4. Termination higher for VPs A & E, lower for others
5. Higher termination for nurses living in Seattle
6. No difference in termination for night versus day shifts
MethodsMethods
For this initial look, we broke down nurses’ turnover into 3 categories: Active, Involuntary, and Voluntary terminations.
We initially looked at differences in age, gender, years since hired, whether they had been rehired, department, ethnicity, and FTE.
We have added comparisons on reporting VP, Seattle residency status, and shift.
We also compared 2 time periods:Before and After Magnet Status
Methods, Cont.Methods, Cont.
For all comparisons except time period, odds ratios (with
95% Confidence Interval) were calculated for each variable:Odds = P(termination)/P(active)Odds Ratio (OR)=odds(Male)/odds(Female), e.g.
Hence, an OR = 1 implies no difference in termination rates, OR > 1, Males (or whatever category) has higher termination rate, OR < 1 lower termination rate
Analyses were done unadjusted as well as with
an adjustment for age and adjustments for age and
experience (years since hire).

Helmet HeadwindAmerican kids need more exercise, but are helmet laws making them ride their bicycles less?Two economists say that could be the case. Helmet laws, they found, are associated not only with fewer bike-related head injuries for children but also with fewer non-head biking injuries. More than 20 states have laws requiring bike helmets, with various age limits, as do localities."For 5-19 year olds," the researchers write, "we find the helmet laws are associated with a 13% reduction in bicycle head injuries, but the laws are also associated with a 9% reduction in non-head bicycle related injuries and an 11% increase in all types of injuries from the wheeled sports."The increase in injuries from other wheeled sports suggests young riders might be shifting to skateboards and roller skates instead of bicycling.

MARKETING (WSJ Feb. 15, Week in Ideas: Daniel Akst)
Buying ConservativelyBringing a new product to market? You'll have a harder time in conservative parts of the country, a paper implies.A trio of business professors studied six years of supermarket purchases in counties covering nearly half the U.S. population and found that, when it comes to groceries, conservatives like established national brands—and are significantly less likely to try new items."These tendencies," the researchers wrote, "correspond with other psychological traits associated with a conservative ideology, such as preference for tradition and the status quo, avoidance of ambiguity and uncertainty, and skepticism about new experiences."Conservative ideology was measured in the study by Republican voting behavior and religiosity. In counties high on both measures, generic products fared worse and new products had lower penetration.

CRIMINAL JUSTICE (WSJ Feb. 15, Week in Ideas: Daniel Akst)
Unreliable, Sober or NotIntoxicated eyewitnesses are no less reliable than sober ones—but neither is very good at picking culprits out of a lineup.Researchers in Sweden gave screwdrivers to two groups of presumably eager volunteers with the aim of a 0.04 blood alcohol concentration in one, and 0.07 in the other—both above the 0.02 Swedish limit for driving but below the 0.08 level that is standard in the U.S.Then the participants, along with an alcohol-free control group, were shown a staged kidnapping on video. A week later the volunteers were asked to pick the kidnappers out of a lineup.All three groups of participants performed about the same—better than chance but poorly nonetheless. The poor showing was in keeping with prior studies.
