About us PICU at Children’s Hospital at the University of Oklahoma in OKC 25 beds ~1600 admissions per year Developing CTS program New surgeon January 2014 ~300 cases 2014

About us Staff 7 full time attendings 1 part time 2 on service during day, 1 on service at night Advance Practice Team 7 full time 2 part time 3 Physician Assistants 6 Acute Care Nurse Practitioners 12 hour shifts

Vision of the APP Provide exceptional patient care with emphasis on continuity education and research

Dilemma With busier cardiac unit and only one physician on at night, how staff APP team most effectively? Meet vision of excellent patient care and continuity Asked AP team recommended a swing shift Looked at VPS data

Extracting Data from MyReports View Report ICU Summary – Here we looked at the which days and time of day the PICU had the most admissions Swing Shift recommended by APP.

APP “Swing Shift” Started August 1, 2014 From 1pm to 1am, Tues-Thurs One APP Predominantly to assist with new admissions and evening coverage in CVICU APP team loved this additional coverage But was it truly helpful with providing excellent patient care?

Study Objective Determine if the addition of the APPs for a “swing shift” three nights per week led to 1. Decreased length of stay (LOS) for pediatric post-operative cardiac patients admitted to the PICU and 2. Decrease in mortality, length of intubation, duration of chest tubes, arterial lines, or central venous lines.

Study Design R etrospective chart review all pediatric post-operative cardiac patients March 1-July 31, before “swing shift” (Group 1) August 1-December 31, after “swing shift” (Grop 2) Data from our Virtual PICU Systems database and Meditech

Using MyReports, a query was built using a population of: Admission dates from March 1, 2014-July 31, 2014 (before swing shift) and Admission dates from August 1, December 31, 2014 (after swing shift). Had a cardiac procedure = yes

Variables included: Age Gender LOS PIM2 ROM score PRISM3 score Disposition Outcome

Extraction of procedure duration for: Endotracheal tubes Chest tubes Arterial Catheters Percutaneous Central Venous Catheters STS procedures divided into Single Ventricle physiology vs not.

Statistics The two groups were compared using: Descriptive statistics (Table 1) Fisher’s exact for categorical variables (Table 2) Wilcoxon-Mann-Whitney for non-normal continuous variables (Tables 2&3) A multiple regression model comparing the “swing shift” with LOS as the dependent variable

Results Group 1 (before “swing shift”) similar to Group 2 (after “swing shift” ) Groups not normally distributed No statistically significant change in LOS after addition of APP “swing shift” (p=0.5423) However, multiple regression analysis revealed trend toward shorter LOS Estimated change in LOS when “swing shift” was available was 0.87 days, or 21 hours Accounted for factors such as patient disposition, PIM 2, age at ICU admission, mortality, single ventricle physiology No significant difference between groups regarding secondary outcomes

Conclusions Trend toward shorter LOS has positive impact Financially (average cost of one PICU day $8,200) PICU resources Families emotionally and psychologically Lack of significance may be related to Small sample size “Swing shift” only 3/7 nights Some patients are transferred back to NICU prior to lines and tubes being removed

Future Studies As the APP team expands, night coverage will increase Just recently expanded to include Monday night swing Team will eventually have full coverage of nights Inotropes Patient satisfaction
