Study design
We applied the explanatory sequenced mixed method design and followed the good reporting of a mixed method study (GRAMMS) framework to report this study (Appendix 1)(19). First, we conducted quantitative research to obtain a general understanding of near miss organizational learning. Then, we selected key informants from the high-, middle- and low-performance nursing units for interviews to perform data triangulation and enrich the previous stage’s research results.
Setting and participants
The study was conducted in a Chinese nursing organization of a tertiary hospital from October 2020 to January 2021. This nursing organization contains 61 nursing units and 1132 nurses. The registered nurses who worked in the front-line clinic were eligible participants. Those who worked in positions other than nursing or on sick leave were excluded. In the quantitative study, the minimum sample size is recommended to range from 285 to 291 based on the size of the organization’s population (1100-1200), and with the estimation of an approximately 50% validation questionnaire rate, the sample size was determined to be 600(20). The participants were identified by the staff list and recruited through random sampling. In the qualitative study, we enrolled participants from high-, middle- and low-performance nursing units by purposive sampling. Data collection and content analysis were conducted at the same time, and the interview was stopped until data saturation.
Data collection
Researchers distributed the survey link, name list and a detailed explanation of the research to head nurses, and they delivered the survey link to respondents. Since the survey contained two questionnaires (85 items), we conducted the survey in two consecutive weeks.
After the completion of the survey, we applied purposive sampling to recruit participants for semi-structured interviews. We divided the surveyed nursing units into high-, middle- and low-scored groups and selected one unit as a representative in each group. Then, we interviewed nurses from various managerial levels from selected units. Interviewers were offered informed consent and asked for permission before audiotaping the interview. The audiotapes were transcribed verbatim, checked for accuracy and imported into NVivo 11.0 after the completion of the interview.
Measures
According to the research questions and the 4I Framework of Organizational Learning, we measured two outcomes: organizational learning behaviour and near miss organizational learning(Table 1).

The Chinese version of Strategic Learning Assessment Map
The Strategic Learning Assessment Map is an instrument built on the 4I Framework of Organizational Learning. It can offer an overall description of organizational learning and diagnose the existing problems (15). It contains six domains: individual-level learning stocks (II), group-level learning stocks (GG), organizational-level learning stocks (OO), feed-forward learning flows (FF), feedback learning flows (FB) and organizational performance (PERF). Each domain has 10 items. All items are rated on a 7-point Likert scale (1=strongly disagree, 7= strongly agree), and the higher the score is, the better the performance. In addition, we can use an equation to calculate the misalignment. The misalignment can reflect the learning absorption, and the equation is Misalignment= (`xII+`xGG+`xOO)/3-(`xFF+`xFB)/2. This instrument has been used in North America and European countries(13, 15); it has already been translated and culturally adapted into Chinese. The Cronbach’s α for the overall scale and its subscales ranged from 0.97 to 0.99, the I-CVI was 0.87 and the S-CVI/Ave was 0.98(21).
Quiz about near miss definition
Researchers developed an item by asking them to select the correct definition among four choices, including definitions of near miss, adverse event, hazard and sentinel event; the higher the accuracy, the better the intuition (4).
The Scale for Second-order Problem Solving Behavioural Intention following Near Miss
Intention for behaviours following near miss can be grouped into two categories: the intention for the first- and second-order problem solving behaviour following near miss(22), among which only the second-order problem solving behaviour can promote the near miss organizational learning and reduce future risk. Researchers applied the Scale for Second-Order Problem Solving Behavioural Intention following Near Miss to test nurses’ intention of near miss coping behaviours (22, 23). Its S-CVI/Ave is 1.0, the overall Cronbach’s a is 0.909 and the Cronbach’s a for its subscales ranges from 0.799 to 0.875. It contains five dimensions: reporting intention, sharing intention among colleagues, intention for cause exploration, practice changing intention and continuous improvement intention. It has 23 items, and all items are rated on a 5 Likert scale, 1=strongly disagree, 5 = strongly agree; the higher the score is, the more likely nurses are to engage in second-order problem solving behaviour.
Problem solving behaviours following near miss
It is widely acknowledged that problem solving behaviours generally include first- and second-order problem solving behaviours. First-order problem solving behaviour occurs when nurses do a quick fix and continue to finish a task that is blocked or interrupted. Whereas second-order problem solving behaviour occurs when nurses do a quick fix, take action to address underlying causes and bring the problem to managers’ attention, error reporting can generally be regarded as a sign of second-order problem solving behaviour(23). Researchers evaluated reporting behaviour following near miss by a self-reported item borrowed from the Hospital Survey on Patient Safety Culture(24). This item is ‘when a mistake is made in your hospital work area/unit, but is caught and corrected before affecting the patient, how often is this reported?’, the participants can choose never, rarely, sometimes, most of the time, or always to describe their reporting behaviours. Their choice can reflect their preference for different types of problem-solving behaviour.
Semi-structured interview guideline
Qualitative interviews were jointly performed through individualized interviews and focus group interviews to avoid power differentials and their negative influence. The interview guideline (Table 2) was developed based on the 4I Framework of Organizational Learning. Researchers conducted individualized interviews with nurse leaders (N=4) and three focus group interviews with 12 nurses at the non-managerial level.

Data analysis
Statistical analysis
Quantitative data analysis Quantitative data were imported and analysed by SPSS 24.0. Means, standard deviations and percentiles were used for statistical description. The hypothesis testing of the Strategic Learning Assessment Map were analysed by structural equation modelling (SEM) using AMOS 25.0. In addition, alpha level was set at p<0.05.
Qualitative analysis Qualitative data were analysed using content analysis (deductive and inductive) by two independent researchers with the following steps: (1) build an analysis matrix under the 4I Framework of Organizational Learning(see Appendix 2); (2) researchers reviewed the transcribed text thoroughly and repeatedly, therefore to be familiar with the text content; (3) researchers analysed and compared their coding with the initial three interviews, then they discussed the discrepancies and developed the initial version of codebook; (4) researchers analysed the following interview and categorized all the codes into the analysis matrix;(5) researchers went through the text for another circle and conducted inductive content analysis, deciding whether there are new codes or categories should be added and then decided the final version of codebook(25).
Integration of data and emergent themes
To integrate qualitative and quantitative data, the findings are displayed together and merged under the analysis matrix.
Validity and reliability/Rigor
We applied various methods to guarantee the credibility, dependability, confirmability and transferability of our research(26).
Credibility ① The qualification of researchers is essential to ensure the credibility of research. All researchers were experienced nursing researchers in quantitative studies and qualitative studies, thus ensuring the credibility of our research. ② In this research, we applied both quantitative and qualitative research to investigate near miss organizational learning (methodological triangulation); in addition, our data were collected from various sources, including surveys, interviews and records in the Adverse Event Reporting System (data triangulation); furthermore, two researchers participated and discussed the coding work until a consensus was made during content analysis (investigator triangulation).
Dependability & Confirmability Researchers recorded every research procedure and all the details on a computer, and research members checked these audits regularly.
Transferability Researchers provided detailed information about the nursing organization, the theory and instruments we applied in this survey; therefore, risk managers in other similar healthcare organizations can easily apply our research results.
Ethical considerations
The study was reviewed and approved by the Ethics Committee of the School of Nursing, Chinese Academy of Medical Sciences & Peking Union Medical College (IRB approval number:201902). All participants were voluntarily participating in this research and we obtained their informed consent before the survey and interview.
