Measuring teamwork and safety culture (climate) across 3 adult intensive care units of a single hospital cluster in Hong Kong Sammei Tam 18 Oct 2009 1
Why study this topic? • Patient safety is an important component in health care quality • Many errors are potentially preventable • Communication breakdown is a common cause of serious adverse events • Encourage to improve patient safety culture and promote team functioning in current healthcare practice (Institute of Medicine Report 1999) 2
Overseas experience • Huang, et al. , Critical Care Medicine (2007) – Significant safety culture variation existed across ICUs of a single institution – Nurses had lower mean scores than Doctors 3
Overseas experience • Kaissi, et al. , Nursing Economics (2003) – Measured teamwork and patient safety attitudes in high-risk areas – No significant difference between 4 hospitals – Nurses favoured team approach, but • Teamwork in departments not very advanced • Problematic communication with some key team members 4
Overseas experience • Thomas, et al. , Critical Care Medicine (2003) – Discrepancy in attitudes on teamwork amongst critical care nurses and physicians – Physicians: more satisfied with physician-nurse collaboration than nurses – Nurses: difficulty in speaking up, disagreements not appropriately resolved – Individuals ranking lower in a hierarchy: often not being asked for comments or information in relation to patient safety 5
This Study • Aims and Objectives – Primary objective : to determine whether teamwork and safety culture (climate) vary between different units in the NTEC cluster – Ultimate aim : to improve team work and patient safety in ICUs • A self-completed structured questionnaire with a few semi-structured questions – Anonymous, voluntary • Subjects and Target Population – All doctors and nurses working in the 3 ICUs – ICU Doctors n = 25 – Nurses n = 184 6
Methodology – Questionnaire Design • Adapted from …Original SAQ-ICU…included 64 items and assessed six safety culture factors. (Sexton, et al. , 2006) • For this study purposes, only the teamwork climate and safety climate factors were used • Each factor is made up of a set of individual questions (10 items in a set for safety and 10 items in a set for teamwork) • When taken together, they comprised a respondent’s perception of the factor • Some of the SAQ-ICU items were rewritten to suit the Chinese language 7
Methodology – Questionnaire Design Factor Definition Example Items Teamwork Climate Perceived quality of collaboration between ICU Doctors and ICU Nurses I have the support I need from other staff to care for patients Safety Climate Perceptions of strong and proactive organizational commitment to patient safety This unit is putting effort to ensure patient safety Modified from Sexton, et al. , . BMC Health Services Research, (2006) 8
Methodology – Questionnaire Design • Final questionnaire contained 30 items • Section A : 2 demographic questions • Section B : 20 Likert scale questions for Culture Factors • Section C : 2 Likert scale questions for impression of collaboration and communication • Section D : 3 multiple-choice (yes or no) questions for incident reporting • Section E : 3 open-ended questions for other comments 9
Pilot study • 5 senior nurses were asked to participate in a content validity exercise to rank the questionnaire in terms of comprehension and appropriateness, and whether the questionnaire retained original meanings 10
Methodology • Ethical Approval from the Joint CUHK-NTEC Clinical Research Ethics Committee • Approval obtained from CCE and senior hospital management • Questionnaire distributed and collected between January and February 2008 11
Methodology • Analysis – Descriptive analysis to determine the frequency of response for each survey item – Compare mean factor scores by ANOVA – Compare percent-favourable scores by Chi-square between each unit and between doctors and nurses • Mean factor score provides a rough point estimate about the factor score of the relevant group • Percent-favourable score is a measure of the % of respondents that gave positive response, i. e. mean score of higher or equal than 75 12
Results • Response Rates – 209 questionnaires handed out – A total of 135 questionnaires were received – One questionnaire was excluded because more than half of the data missing – Total valid questionnaires were then counted as 134 – An overall response rate was 64. 11% Response Rates Respondents Doctors Nurses Unit Rec.

Results Differences of Perception across ICUs • The safety factor scores among the three ICUs were very close to each other and also the teamwork factors scores • ICUs did not uniformly have high factor scores or low factor scores • The percentages of staff members of a given group with favourable scores > 75 on safety and teamwork factors were less than half Mean Score Teamwork % favourable Score Safety Unit A 69. 86 63. 63 38. 03 14. 08 Unit B 68. 87 63. 00 32. 08 22. 64 Unit C 68. 51 65. 00 40. 00 10. 00 P value 0. 836 0. 921 0. 978 0. 269 Safety Teamwork 14
Results Differences of Perception between Staff Groups • Discrepancies in perceptions between doctors and nurses • Doctors tended to perceive the factors more positively than nurses • Ratings for safety factor by all nurses and doctors were higher than for teamwork factor Mean Score Safety Teamwork 70. 39 % favourable Score Safety Teamwork All Doctors 72. 31 46. 15 30. 77 All Nurses 69. 05 62. 87 34. 71 13. 43 P value 0. 276 0. 032* 0. 588 0. 496 *Statistically significant 15
Results Differences of Perception between Staff Groups for individual ICUs • Significant differences found in Unit A & Unit C; Dr perceived more positively • Nurses at Unit B had a higher rating on safety factor than doctors; Highest % on Teamwork among nurses • None of the nurses in Unit C responded favourably towards teamwork Unit A Doctor Nurse P value Unit B Doctor Nurse P value Unit C Doctor Nurse P value Mean Score Safety Teamwork 79. 50 69. 13 0. 018* 67. 15 69. 29 0. 493 80. 00 67. 22 0. 137 76. 50 62. 65 0. 014* 63. 93 63. 21 0. 887 85. 00 62. 28 0. 017* % favourable Score Safety Teamwork 60. 00 36. 40 0. 049* 28. 57 32. 61 0. 656 100. 0 33. 33 0. 046* 40. 00 12. 12 0. 125 28. 57 21. 74 0. 569 100. 00 - *Statistically significant 16
Results Response to Incidents Reporting • Only 130 out of 134 respondents had answered • 52 (Nurse n=47, Dr n=5) out of 130 have involved in patient safety related incidents • 14 out of 52 did not report incidents provided reasons: – may not be blame free – not anonymous – near miss incidents and immediately corrected by colleagues 17
Results Perceptions on Communications • Discrepant attitudes about collaboration and communication between doctors and nurses • Doctors perceived more satisfactory in communication than nurses • All differences reported were not statistically significant 18

Conclusions • Minimal differences on safety and teamwork climate exist across the ICUs within the cluster • Doctors were more positive in their perceptions of safety and teamwork than nurses in their working units • Doctors perceived communication more satisfactory than nurses • Findings were consistent with previous studies using SAQ in ICU • Reluctance to report incidents to supervisors 21
Recommendations 1. Repeat survey periodically to monitor culture change 2. Efforts should better direct to team-based training 3. Promote a positive working environment, result in good teamwork, enhance job satisfaction and improve nurse morale 4. Provide a starting point for understanding patient safety culture issues to leaderships in future planning of improvement programme 22
