The goal of this observational study is to evaluate an innovative pediatric transitional care unit called the Jeroen Pit Huis (JPH). The primary objective of our study is to investigate whether an intermediate stay between hospital and home in the JPH have a favourable effect on healthcare consumption, patient, parent and family-relevant quantitative outcome measures, compared to discharge directly from a hospital ward. Parents will be asked to complete several questionnaires on three different time points (at discharge, 3 and 12 months of follow up).

Rationale: Children with Medical Complexities (CMC) often require 24/7 expert care for which often prolonged (re)admissions in a university medical centre (UMC) are necessary which, in turn, impedes discharge home. Hospital to home transitions of CMC is a multi-faceted process with many challenges and obstacles. This protocol describes the evaluation of an innovative Transitional Care Unit (TCU) called the Jeroen Pit Huis (JPH), that aims to supports this transition.

Hypothesis: We hypothesize that an intermediate stay between hospital and home in the JPH will have a favourable effect on healthcare consumption, patient, parent and family-relevant quantitative outcome measures, compared to discharge directly from a hospital ward.

Objective: The primary objective of our study is to investigate whether an intermediate stay between hospital and home in the JPH lowers parental distress compared to discharge directly from a hospital ward. Furthermore, the effect on quality of life (QoL) in children and parents, growth, family functioning, impact on parental employment, parental self-efficacy, anxiety, depression, sleep disturbance, posttraumatic stress (PTSD), care satisfaction, and healthcare consumption will be assessed with and without an intermediate stay in the JPH.

Study design: Multicenter quasi-experimental prospective cohort study

Study population: Patients (term newborns up to the age of 18 years) who; (1) are admitted in the hospital with (a deterioration of) a chronic complex condition (CCC) and/or have (expected) continuous dependence on technology after discharge; (2) require specialized medical and/or allied health care after discharge; (3) are medically stable and/or have a set treatment regime and; (4) are not yet ready to be discharged home due organization-, care- or family circumstances.

Intervention (if applicable): Not applicable, since the JPH is the standard of transitional care in the Amsterdam UMC.

8. Satisfaction of the parents with the received care at JPH/hospital discharge

9. Healthcare consumption during 12 months of follow-up

Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Subjects do not benefit personally from study participation. This non-therapeutic research with minors will have negligible risks. The main burden of participation in this study is the need to complete several questionnaires in total on three different time points. The expected required time-investment of the children and their caregivers is approximately 2.5 hours in total (around 50 minutes at 3 different time points). Furthermore, it requires time and effort from physicians to screen and patients for inclusion.

Subject eligibility (or inclusion) criteria for this are as follows:

1. Age: at term (older than 37 weeks corrected gestational age) and younger than 18 years
2. Admitted to the hospital with (a deterioration of) a chronic complex condition (CCC) [30] and/or (expected) continuous dependence on technology after discharge (see ad 2 below).
3. Expected need of specialized medical and/or allied health care after discharge
4. A stable medical condition and/or a set treatment regimen (see below ad 4)
5. Discharge home not yet possible due to organization-, care- or family circumstances (see below ad 5)
6. Have given informed consent (consenting process is described in chapter 11.2 recruitment and consent)

Ad 2 chronic complex condition Fulfils criteria of a chronic complex condition (CCC) [30] and/or (expected) continuous dependence on technology after discharge.

A complex chronic condition (CCC) is defined according to Feudtner et al. (1) as "any medical condition that can be reasonably expected to last at least 12 months (unless death intervenes) and to involve either several different organ systems or one organ system severely enough to require specialty pediatric care and probably some period of hospitalization in a tertiary care center." Verlaat et al., updated the CCC list based on expert opinion [31]. A table of diagnosis classified as CCC can be found in appendix 1. An unknown but suspected complex and chronic condition, such as a child born with multiple congenital anomalies but lacking a unifying diagnosis, will be included.

Ad 4 stable medical condition

The patient is defined as being in a stable medical condition if there is:

1. A patent, safe airway to remain in the home situation, whether or not by means of a trachea cannula
2. Adequate respiration, whether or not by means of (intermittent) support with oxygen, non-invasive ventilation or invasive ventilation via a trachea cannula
3. A neurologically stable condition that may include temporary neurological impairments (such as seizures) not interfering (potentially life-threatening) with other vital functions such as respiration or circulation
4. Drug treatment that can be given at home where (if applicable): a nasogastric, duodenal or jejunal tube and/or a percutaneous endoscopic gastrostomy (PEG) tube is in situ, or if necessary, a 'home-proof' intravenous access is guaranteed
5. In case of enteral tube feeding, the nasogastric, duodenal or jejunal tube and/or a percutaneous endoscopic gastrostomy (PEG) tube is in situ, and the feeding schedule may be built up, reduced or variable if there are no contraindications for this. In case of parenteral feeding, the parenteral nutrition home program must be organized according to the home situation.

Ad 5 organization-, care- or family circumstances include the lack of 1 or more of the following requirements for safe discharge home:

1. A sustainable care plan using the four 'Medische Kindzorg Systeem' domains (medical, safety, development and social) has been drawn up that includes all four domains such as among others (Medical Child care System that is used in The Netherlands to structure medical child care in the home situation):

   • care needs
   • clear coordination of tasks and responsibilities of parents and healthcare professionals (primary, secondary and tertiary care).

2. The necessary medical and nursing care support (such as a feeding pump, adequate home care).

3. Parents know who to contact with questions about the organization of care (e.g. financial issues, wheelchair, municipality)

4. Essential medical technology is available at home and can be used for care.

5. Reimbursement of care at home is adequately arranged.

6. The house is located and furnished in such a way that the child can stay in it safely (accessibility for emergency services, telephone contact with parents, technical facilities)

   Parents/informal carers are adequately trained to take care of the child in the home situation, that means that they:

7. Master care in all areas (medical, nursing, technical, psychosocial)

8. Obtain declaration of care competencies, in particular:

   • assessment for somatic deterioration
   • acting in emergency situations (e.g. seeking help, resuscitation and if applicable: cannula dislocation, PEG probe problems, docking of a seizure)
   • realizing when to call for help and whom to call for help

9. Can obtain adequate telephone assistance (working telephone, English/Dutch speaking)

10. Are psychologically and emotionally ready to deal with new home situation (according to care professionals)

A potential subject will be excluded from participation in this study if:

1. The patient is in need of end-of-life care
2. Existence of predominantly social/family issues without serious medical problems in the index child
3. Patient with behavioural/psychiatric problems necessitating other type of care
4. Patient requiring rehabilitation medical care
5. Patients who are not directly discharged home from the hospital (except for the JPH (e.g. via de Boeg, Villa Expert Care))
6. Contagious disease that requires strict isolation

The population exists of all children admitted to one of the four UMCs. The population will be predominantly CMC. CMC have one or more chronic conditions, functional limitations, high family identified needs, and a high use of healthcare resources [1]. Eligible participants fulfil all inclusion and no exclusion criteria.
