The Effect of the Close Collaboration With Parents Intervention - Estonian Study

Materials and Methods: Design A quasi-experimental, before and after intervention, design is used to test the effect of the intervention, where the impact mechanisms are treated as mediators of the change.

Sample: The subjects are employees of five neonatal units of three Estonian hospitals participating in the Close Collaboration with Parents intervention (hereinafter: staff) and newborns cared for in the units and their parents (hereinafter: families). Three of the units are at Tallinn: West-Tallinn Maternity Hospital (NICU and neonatal unit), the Department of Anesthesiology and Intensive Care (PICU/level IIIB), and the Department of Neonatal and Infant Medicine (NICU/level II) at the Children's Hospital. Another two units are located in Tartu University Hospital: the Department of Neonatal and Pediatric Intensive Care (PNICU, level IIIC) and a step-down unit (level II).

Families are recruited during a four-month period before and after the intervention, with the aim to recruit at least 50 families per participating hospital in both periods. Some newborns may be treated in a different hospital or in different units of the same hospital. In the case of a transfer, the family is asked to fill in only the Family Center questionnaire if the newborn has been in that unit for more than 72 hours.

A log will be kept of all infants discharged home from the unit i.e. to evaluate drop-out rate and biases. The log includes the patient's gestational age, birth weight, diagnosis, type of feeding at discharge, and length of hospital stay. If there is missing information in the log, it is completed with the information from the medical records. A log is also kept to follow the units' restrictions related to Covid-19 and concerning family visitation and participation policies.

Outcomes:

The fidelity is analyzed by tracking the participants' behavior in the e-learning module with analytic software, such as Google Analytics, Hotjar, and Vimeo. The participants are informed about this and they are asked for their written consent and agreement when entering the module for the first time. Furthermore, a log is kept about the practices the mentors are carrying out with their colleagues in the units.

Staff outcomes Background questionnaire A questionnaire is used to collect background information on staff members Collaboration competence questionnaire A questionnaire is used to assess the collaboration competence of the staff at the beginning of the intervention, in the middle of the implementation, and at the end. The questionnaire is specifically created to assess competencies that are relevant to the Close Collaboration with Parents training program. The questionnaire includes 21 questions that are evaluated with a scale from 1 to 10 (1=not competent at all, 10=extremely competent). If the question does notably the daily work role of the professional option, "Doesn't belong to my role" can be used.

The reflective thinking The level of reflective thinking of the staff is measured using the Reflective Thinking Measure. The 16-question measure determines whether an individual engages in reflective thinking and to what extent s/he does that. The questions are answered with options varying from strongly agree, which is scored as 5, to strongly disagree, which is scored as 1. The 16 questions form four factors: 1) Habitual Actions, 2) Understanding, 3) Reflection, and 4) Critical reflection. The structural validity of the scale has been tested on healthcare professionals and it has been shown to be good.

The level of reflective thinking is also assessed with questions related to a fictitious case. The case represents a so-called 'critical incident' that the staff is asked to describe from three perspectives: (a) how they would normally act in a similar situation in their unit; (b) a general meaning and reflect how the general meaning resonates with their own experience; and (c) potential new ways of acting in the situation that would provide better support for the family The FCC care provision The perception of multi-professional staff members on parent support they have given that day is measured with DigiFCC web questions. The question will reflect the staff's point of view on the support provided for parents in the following dimensions: 1) active listening, 2) parent participation in infant care, 3) individualized parent education, 4) parent participation in decision-making, 5) the parent trust staff in infant care, 6) the staff feel the parents trust them in infant care, 7) participation in medical round/medical care decision making, 8) information sharing, and 9) emotional support. Staff members answer the questions through a website that is always open on the research computer in the unit. Every staff member (regardless of qualifications) working in the participating units is asked to answer a daily question through a website after each work shifts for a 3-month period. There are 9 questions that are randomized in 3-question blocks. Answers are numbers from 1 to 5 or 0 if the staff member hasn't been working with the parents on that shift or didn't participate in the medical round.

Regarding the same 4-month period, the researcher/administrator collects the number of nursing staff working shifts in the unit to calculate the response rate. The research will create a questionnaire for each unit through the Master account website. The responsible researcher will have access to the research account to collect the answers.

Family outcomes Infant-parent background questionnaire A questionnaire is used to collect background information on infants/parents Parents' depressive symptoms The depressive symptoms of parents are measured with Edinburgh Postnatal Depression Scale (EPDS). The 10-question EPDS is a valid method to measure depressive symptoms both in mothers and fathers. The 10-question scale includes symptoms such as insomnia, mood, tearfulness, and thoughts of self-harm. The scale asks how the parent has felt during the previous week. The parents rate each question on a scale from 0 to 3. The EPDS is easy to administer and has high sensitivity as a screening tool.

Parent's anxiety symptoms The anxiety symptoms of the parents are assessed with State and Trait Anxiety Inventory (STAI). State anxiety is an emotional reaction that varies from one situation to another, whereas trait anxiety is a personality characteristic. The STAI measurement provides separate scores for both types of anxiety. There are 20 questions about state anxiety that are rated with a 4-point scale (1=not at all, 4=very much) and 20 questions about trait anxiety that are also rated with a 4-point scale (1=almost never, 4=almost always). The recommended cut-off for postnatal anxiety measured with STAI-S is 34/80.

The research assistant will calculate the parent's scores of EPDS and STAI-S when the questionnaires are returned. She informs the responsible researcher of the unit if the total score of the EPDS is >12 or if the parent has suicidal thoughts and if the total score of STAI-S is >33.

Parenting self-efficacy scale Parenting self-efficacy is measured Perceived Maternal Parenting Self-Efficacy (PMP S-E) instrument. The PMP S-E instrument consists of 20 items (scoring ranges 20-80) with four subscales: 1) care-taking procedures, 2) evoking behaviors, 3) reading behaviors or signaling, and 4) situational beliefs. The items are rated with a four-point Likert scale ranging from 'strongly disagree' (score 1) to 'strongly agree' (score 4). The PMP S-E tool is a psychometrically robust, reliable, and valid measure of parenting self-efficacy in mothers of relatively healthy hospitalized preterm neonates.

Parent's readiness for discharge The readiness for discharge is measured with the Readiness for Hospital Discharge Scale (RHDS). The questionnaire includes 23 items. Four attributes of readiness for discharge are measured within the subscales: Personal Status (7 items), Knowledge (7 items), Coping Ability (4 items), and Expected Support (5 items). Answers are on a 10-point scale from 0 to 10 (not at all - totally). The RHDS has been shown to be a reliable and valid measure of patients' perception of readiness for discharge.

Parent's perceived FCC The parent participation and the support parents feel they receive from the staff is measured using a questionnaire modified from DigFCC SMS questions. The questionnaire includes 9 questions covering the following aspects of staff support 1) active listening, 2) parent participation in infant care, 3) individualized parent education, 4) parent participation in decision-making, 5) the parent trust staff in infant care, 6) the parent feel the staff trust them in infant care, 7) participation in medical round/medical care decision making, 8) received information, and 9) emotional support. They are asked to answer the question with the Likert scale from 1 to 7 (1=not at all-7=very much; 0= if they did not visit the unit).

Data management The investigators will utilize REDcap (Research Electronic Data Capture) for data transfers from Estonia to Finland and for data storage. REDcap is an electronic tool for data collection that is provided from the server facilities owned and operated by the University of Turku IT Services, which also means all data collected to the system is stored and kept at the University of Turku. When the data is stored in the online file storage of Turku University it is automatically copied to three independent servers that also function as data backup systems.

Data security description:

• Centralized administration by separate administration accounts and compartmentalized user privileges
• Use of current and reliable hardware, and software which is updated continuously
• Centralized identity management (IDM)
• Locally administered industry-standard network infrastructure and services
• Common server platforms with minimal tailoring
• Continuous monitoring of network traffic patterns and service statistics
• Widely deployed security software and other monitoring tools The principal investigator (PI) controls access to the data. The co-researchers can approach the PI to request access to the data. The PI will apply to the University of Turku IT Services to provide the access to the online storage. If a co-researcher is not working at the University of Turku, the PI can ask the IT services to give that person a visitor status and, thereby, access to the online file storage. All new users are identified using government-issued identification documents or by citizens' identification and payment service. The IP will keep a record of those who have active access to the data.

All the data will be handled anonymously. The participants will get an ID code that is used when data is stored and analyzed. The recruitment log of the parents and staff members are used to undo the ID codes and, therefore, they are kept separately from the data files. The analytic software (Google Analytics, Hotjar, and Vimeo) also track anonymously participants' behavior on the e-learning module's website. The personal details (password, email, etc) are not recorded and the IP addresses are anonymized by cutting out the last few digits, so only the rough geographical area of access to the e-learning module is identified. The logs and all the data will be destroyed five years after the last publication of the data.

Ethical considerations Ethical approval for the study protocol was given by the Research Ethics Committee of the University of Tartu on the 10th of February 2021 (no: 3331T-21). Written informed consent will be obtained from each staff member and parent before study participation. The analytic software (Google Analytics, Hotjar, and Vimeo) will be activated only after consent has been obtained from a participant. The application for ethics includes an opportunity to complete the information received from the parents (infant and family characteristics questionnaire) using patient medical records.
