In today’s data-driven age, healthcare is transitioning from opinion-based decisions to informed decisions based on data and analytics. Analyzing the data reveals trends and knowledge that may run contrary to our assumptions causing a shift in ultimate decisions that in turn will better serve both patients and healthcare enterprises. Abstract
Helmet laws “helmet laws are associated with a 13% reduction in bicycle-related head injuries, a 9% reduction in non-head bicycle-related injuries, and an 11% increase in all types of injuries from the wheeled sports.“ Buying habits “conservatives like established national brands—and are significantly less likely to try new items” Sober vs. intoxicated eye witnesses “Intoxicated eyewitnesses are no less reliable than sober ones, and neither is very good at picking kidnappers out of a lineup” WSJ Data news: Last weekend, Feb

This talk illustrates our collaborative work with key stakeholders, including executive leadership, and describes a few representative, data-driven, and cost-effective projects. Abstract, Cont.
US News & World Report (USNWR) Metrics Sponsors: David Fisher, SVP, Medical Director and Tom Hansen, CEO Objective: to prioritize enterprise-wide improvements based on USNWR Metrics (utilized as Hospital & Departmental Metrics) Prioritized Improvements
Prioritized Improvements, Cont. Three key recommendations: 1. Focus on care and outcomes for A1 and A2 Departments (medical service lines) 2.A1 and A2 Department-specific Marketing 3.Implement 1-Day Immunization Reporting This work is described in Kolker E. & Kolker E., Chief Data Officer in Healthcare: Predictive Analytics Transforms Data to Knowledge to Action, In: Chief Data Officer: Enterprise Data Solution for Business Challenges, MIT Press, 2013, in press. Since 2007, SC moved from 11th to 6th rank

2. Implement 1-Day Immunization Reporting All categories have both general & departmental measurements 1. Advanced clinical services -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
Nurses’ Turnover Trends Sponsors: Lisa Brandenburg, Hospital President and Steven Hurwitz, VP, HR ASK: something is happening with nurses WHAT? WHY? and HOW to deal with it? 3. Personnel + Reduction of Waste
Nurses’ Turnover Trends 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. 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
Methods 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. 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).
Conclusion 6: SHIFT (Night vs. Day) Termination looks higher on night shift, but the difference gone after adjusting for age and experience.
Conclusion 5: ZIP in Seattle (Seattle vs. Other areas) Termination higher for nurses living in Seattle.
Conclusion 4: VPs (vs. other VPs) Involuntary Termination Involuntary termination higher for A and E. Note – OR = 1 for D (Unadj. and Age Adj.). UnadjustedAge Adj.Age and Exp. Adj A E D C B
29 Conclusion 2: Before and After Magnet Status Experience of Terminated Nurses Experience of terminated nurses is higher After Magnet Status (Age Adj.). Mean Experience Involuntary Termination Voluntary Termination Before Magnet After Magnet0.81.5
3. Three Follow-up Actions 1.Discussions with (experienced) nurses 2.Bringing external consultant in-house (psychology, sociology, nursing) 3. Hiring re-adjustments
Bottom Line for 2. & 3. Do you want to: A: Improve the health of your patients B: Cut huge amounts of waste C: Increase your rankings? How about all three?

Radom representation of data today: REGULATION (WSJ Feb. 15, Week in Ideas: Daniel Akst) Helmet Headwind American 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. "Effects of Bicycle Helmet Laws on Children's Injuries," Pinka Chatterji and Sara Markowitz, National Bureau of Economic Research Working Paper (February) American kids need more exercise, but are helmet laws making them ride their bicycles less?
Radom representation of data today: MARKETING (WSJ Feb. 15, Week in Ideas: Daniel Akst) Buying Conservatively Bringing 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.

Radom representation of data today: CRIMINAL JUSTICE (WSJ Feb. 15, Week in Ideas: Daniel Akst) Unreliable, Sober or Not Intoxicated 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. "Do Sober Eyewitnesses Outperform Alcohol Intoxicated Eyewitnesses in a Lineup?" Angelica Hagsand and four other authors, The European Journal of Psychology Applied to Legal Context (January) Intoxicated eyewitnesses are no less reliable than sober ones—but neither is very good at picking culprits out of a lineup.
