Abstract

Introduction Chronic diseases among children are associated with lower health-related quality of life (HRQOL) and higher utilisation of healthcare services. Integrating Patient-Reported Outcomes Measures (PROMs) in routine clinical care has been shown to reduce utilisation of healthcare services while improving patient outcomes. The objectives of our study are to: (1) identify previously implemented and evaluated PROMs for chronic conditions in paediatric settings; (2) consolidate the evidence to evaluate the impact of using PROMs on HRQOL, healthcare utilisation, patient outcomes (eg, symptoms control) and quality of care among paediatric patients with chronic conditions. The findings from this review will inform the future integration of PROMs in paediatric clinical practice.

Methods and analysis We will systematically search the following electronic databases: MEDLINE, EMBASE, CINAHL, PsychINFO and Cochrane library. Reference lists of included studies will also be searched in Web of Science (Thomson Reuters) database to ensure more complete coverage. Two reviewers will independently screen the studies and abstract the data using standardised form. Extracted data will be analysed and synthesised. Finally, a narrative synthesis of summarised data will be presented.

Ethics and dissemination Ethical approval is not required, as the proposed systematic review will use data from published research articles. The results of this study will be disseminated through publication in peer-reviewed journals, scientific conferences and meetings, and the lead author’s doctoral dissertation.

Strengths and limitations of this study

  • A key strength of this study is that it is a first systematic review to evaluate the impact of Patient-reported Outcome Measures on the Health-related Quality of Life , utilisation of healthcare services, patient outcomes and quality of care among paediatric patients with chronic conditions.

  • The findings of this study will provide crucial evidence for integration of PROMs in paediatric clinical care.

  • Another strength of this systematic review is that patient-partners will be consulted to assess the face validity of the included studies to verify if the extracted data is meaningful from patients’ perspective.

  • Exclusion of studies that are not published in English is a potential limitation of this systematic review.

Introduction  

Children with chronic diseases report having a lower health-related quality of life (HRQOL) and higher utilisation of healthcare services compared with their healthy peers; they require complex care.1 Higher utilisation of healthcare services, including higher rates of hospitalisation for these populations, poses a challenge for healthcare systems to provide quality care to children with chronic diseases.2 3 According to the WHO’s definition, chronic diseases are those that are not passed from person to person, they are of long duration and generally have slow progression.4

Patient-reported outcome (PRO) are defined as ‘the measurement of any aspect of a patient’s health status that comes directly from the patient (ie, without the interpretation of the patient’s responses by a physician or anyone else)’.5 Patient-reported outcome measures (PROMs) are the tools or instruments used to measure PROs. Evidence from adult populations suggests that the integration of PROMs in clinical care enhances patient-clinician communication by increasing the frequency of discussion of patient outcomes during consultations.6 Among patients with metastatic cancer, integration of PROMs in routine clinical care was associated with increased survival compared with usual care,7 among patients with arthritis, it improved self-perceived health and disease activity.8 It also reduces the use of healthcare services by improving symptom control, increasing patient satisfaction ultimately improves HRQOL.6 9–12 PROMs are mostly self-completed questionnaires that measure the patient’s health status by asking them about outcomes, such as their symptoms and aspects that may be affected by the disease(s) and/or treatment, including physical, psychological, social, overall well-being and HRQOL.5 13 14 PROMs are standardised and validated questionnaires that are either generic or condition-specific. Generic PROMs can be used for all patients which allows comparison of outcomes between different patient groups.15 On the other hand, condition-specific PROMs are used for specific conditions, making it more sensitive to outcomes associated with that particular condition. This systematic review aims to identify previously implemented and evaluated generic or condition-specific PROMs in paediatric settings including home, community, outpatient and inpatient healthcare settings.

PROMs also generate ‘patient-centred data’, so PROMs are increasingly being used as organisational performance measures by clinicians and healthcare administrators to enhance the quality of care.16 17 Although PROMs are being used to assess the effectiveness of new treatment regimens or surgical procedures, or improve quality of care, evidence around their effectiveness in paediatric clinical care are still scarce.18 Due to the scarcity of evidence, they have not been systematically integrated into clinical care.19 20 To fill this evidence gap, the current systematic review aims to evaluate the impact of PROMs on HRQOL, utilisation of healthcare services, patient outcomes and quality of care among paediatric patients with chronic conditions.

Health-related quality of life

According to the WHO, HRQOL is ‘individual’s perception of their position in life in the context of the culture and value systems in which they live and in relation to their goals, expectations, standards and concerns’.21 Chronic conditions pose a greater risk for psychosocial issues among children,22 so the use of PROMs in clinical care may be helpful in identifying, discussing and eventually resolving aspects associated with HRQOL for these populations. Therefore, it is important to consolidate evidence on the use of PROMs and assess whether their implementation in clinical care can feasibly improve HRQOL and outcomes among children with chronic diseases.

Healthcare utilisation

Chronic diseases among children are associated with higher use of healthcare services including higher hospitalisation rates and length of stay in comparison to healthy children.23 24 Evidence from adult patient populations suggests that the lower scores on PROMs were strongly associated with higher risk of death and hospitalisation.25 The use of PROMs is associated with improved symptom control and increased supportive care measures.6 Further, using PROMs in clinical care enables patients in the self-management of their long-term chronic conditions.26 For the parents of paediatric patients, caring for their hospitalised child often results in lost income and additional strain.22 This is in addition to the detrimental impacts hospitalisation can have on the social and economic status for the child in adulthood.27 28 Considering the potential of PROMs to identify patients at greater risk for healthcare utilisation,7 it is essential to gather evidence regarding the role of PROMs on healthcare utilisation.

Quality of care

Researchers are increasingly utilising PROMs to assess performance of healthcare providers to improve the quality of care and patient satisfaction.29 PROMs can play an important role in providing patient-centred care by focusing on the patient’s health goals and guiding therapeutic decisions.30 Healthcare systems have been incorporating advanced electronic platforms to support and simplify the implementation of PROMs in the clinical setting.18 31 32 The use of PROMs data in an integrated manner would enable healthcare systems to orient evidence-based and patient-centred care. Evidence gathered through this systematic review will help healthcare systems to support quality improvement initiatives and develop effective strategies to further enhance quality of care.

Objectives

The objectives of our study are to: (1) identify previously implemented and evaluated generic or condition-specific self-reported PROMs for chronic conditions in paediatric settings; (2) consolidate the evidence to evaluate the impact of using PROMs on HRQOL, healthcare utilisation, patient outcomes (eg, symptoms control) and quality of care among paediatric patients with chronic conditions.

Methods and analysis

Design

This protocol was developed according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols(PRISMA-P) checklist,33 while the administration of the review and reporting will be carried out according to the PRISMA guidelines.34 The protocol for this review has been registered with PROSPERO, an international database of prospectively registered systematic reviews in health and social care.

Patient and public involvement 

Patient-partners will be consulted to assess face validity of the included studies. The patient-partners are five individuals (three patients and two family-caregivers) that are members of the larger patient and family advisory group at the Alberta Children’s Hospital. They will not be involved in developing research question, design and conduct of this review.

Search strategy

Our search strategy was developed according to the research question and guided by the study objectives. Keywords used for each key domains of the research question are as follows:

Population: Keywords ‘child’, ‘adolescent’ and ‘pediatric care’ will be used to identify studies focusing on paediatric populations (18 years or younger).

Intervention: The interventions of interest for this review are PROMs, so keywords ‘patient-reported outcomes’, ‘patient outcome assessment’ and combination of ‘outcome’ and ‘measures’ along with the associated abbreviations (PRO, PROM) will be used to capture studies implementing these measures in clinical care.

Outcomes: The medical outcomes of interest for the systematic review are the impact of PROMs on HRQOL, healthcare utilisation, patient outcomes and quality of care. Keywords associated with the use of healthcare services including ‘visits to emergency services’, ‘length of stay’, ‘patient admission’ and ‘patient readmission’ nurse-patient relations’ and ‘physician-patient communication’ are used to capture studies focusing on the overall utilisation of these services. Keywords associated with patient outcomes—‘HRQoL’, ‘quality of life’ and the indicators for the quality of healthcare will be used to build a robust search strategy which will include studies reporting these outcomes. The Boolean operator ‘OR’ will be used to combine terms within each outcome category. Finally, the Boolean operator ‘AND’ will be used to combine these concepts. English language filter will be applied on the final search results.

Information sources

We will systematically search MEDLINE (Ovid interface, 1950 onwards), EMBASE (Ovid Interface, 1974 onwards), CINAHL Plus with Full Text (EBSCOhost interface, 1982 onwards), PsycINFO (Ovid interface, 1803 onwards) and Cochrane Library (Ovid Interface, 1991 onwards). In addition to these electronic bibliographic databases, the reference lists of included studies will be searched in Web of Science (Thomson Reuters) database to ensure more complete coverage of the literature.

The search strategy for MEDLINE was developed iteratively with input from this systematic review team and support from a medical sciences librarian who has expertise in systematic review searching at the University of Calgary. As part of this iterative process, a primary search strategy was applied and 100 randomly chosen abstracts were reviewed by the systemic review team. These randomly chosen abstracts helped to specify the search strategy to ensure that it retrieves a high proportion of the eligible and key studies in this area. This revised search strategy was finalised after consulting again with the medical sciences librarian at the University of Calgary, and again after reviewing it with the senior researchers on the systemic review team with expertise in patient-oriented research.

Study design limits will not be imposed on the search. Implementation of PROMs in routine clinical practice mainly started after the year 2000, so we will apply the time limit to exclude studies before the year 2000. Due to limited capacity in translating non-English articles, our literature search will be limited to the English language. Based on the recent evidence,35 we do not expect to introduce a systematic bias due the use of language restrictions in our systematic review. The MEDLINE strategy (see online supplementary appendix for the full MEDLINE [Ovid interface, 1950 onwards] search strategy) will be tested and adapted to the syntax of all other databases.

Supplemental material

Selection of studies

Specific inclusion and exclusion criteria outlined below was developed after reviewing 100 randomly chosen abstracts by the members of the systematic review team (BM, AC and SB) and through consultations with the librarian (DL) and senior researchers (M-JS and LH).

Inclusion criteria:

  1. Studies including paediatric population and questionnaires completed by paediatric patients with chronic conditions (up to 18 years old).

  2. Studies focusing primarily on the implementation and use of PROMs in paediatric chronic diseases.

  3. Studies reporting primary data.

  4. At least one of the following outcomes was reported: HRQOL, symptom control, mortality, healthcare utilisation, quality of care.

Exclusion criteria:

  1. Studies reporting the use of PROMs for acute conditions, dental problems, pharmaceutical drug testing or surgical outcomes assessment.

  2. Studies utilising secondary or retrospective data on PROMs.

  3. Studies validating PROMs or testing methods for collecting/analysing PROMs.

  4. Descriptive studies and reviews on PROMs to describe burden of disease and treatment

  5. Studies reporting findings in languages other than English.

  6. Studies published prior to the year 2000.

Data management

Literature search results will be uploaded to EndNote Reference Management Software V.8. EndNote will be used to remove duplicate references, screen and manage all the references throughout the review process. A PRISMA flow diagram will be constructed to summarise the selection process.

Selection process

For the primary screening stage, titles and abstracts of the studies retrieved will be independently screened in duplicate by two reviewers working in pairs (SB, AC and BM) using the pre-determined eligibility criteria. This will reduce the potential for individual bias and the possibility of excluding relevant articles. Following the primary screening of the abstracts, full-text articles will be retrieved for studies meeting eligibility criteria or where titles or abstracts do not provide sufficient information to warrant their exclusion. Disagreements between reviewers will be resolved through discussion, and a third reviewer will be approached if the disagreement persists. Neither of the reviewers will be blind to the journal titles, study authors or the institutions. At the full-text review stage, reasons for excluding studies will be recorded.

Data extraction

Two reviewers (SB and AC) will independently extract data from the included studies using a standardised data extraction form to reduce errors in data extraction. This form will be pilot tested by two reviewers (SB and AC). The data extraction form will include definitions of the variables to be extracted.

The following data will be extracted:

  1. Summary data of included studies including author, year of publication, paediatric setting (tertiary, community care), location, patient population characteristics, chronic condition under study.

  2. Type of PROM identified with descriptive statistics summarising general characteristics (Including name of the PROM, generic vs condition-specific and mode of administration, collection and reporting).

  3. Reported outcome(s) of interest (Including impact on HRQOL, healthcare utilisation, patient outcomes and quality of care).

Extracted data from included studies will be presented to the whole research team to ensure consistency in data extraction. At this stage, patient partners will be consulted to verify if the extracted data is meaningful from the patients’ perspective, ensuring that our study conforms to patient-oriented research. Consultation sessions will be organised with the patient-partners, where they will be briefed on the process of synthesising evidence through systematic review. The process and extracted data will be presented to them in lay terms. Then, face validity will be assessed by asking them if this systematic review measures what it purports to measure and if those findings make sense from patient’s perspective.

Data synthesis

Finally, a PRISMA flow diagram will be presented to report the number of studies identified, screened and included in the final synthesis. Extracted data including participant characteristics, type of PROMs, geographical location, type of healthcare setting will be summarised in a table. Considering the scarcity of studies assessing the effectiveness of PROMs in routine clinical care of paediatric patients with chronic conditions, we do not anticipate conducting a subgroup analysis of generic versus condition-specific PROMs intervention. Post hoc analysis will be conducted to explore the effectiveness of PROMs on each outcome of interest. Narrative synthesis of the summarised data will be conducted to present the results of the review. Meta-analysis will be conducted using a random-effects model if there is sufficient homogeneity in terms of study design, type of intervention, comparators and outcomes among included studies. Publication bias will be assessed using funnel plot. Risk of bias in individual studies will be assessed independently by two reviewers (SB and AC) using the COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN) guideline for systematic reviews of PROMs.36 Assessing the methodological quality of included studies is important, but it is also recommended to assess the quality of PROMs included in the studies.36 This review might identify studies which used unvalidated PROMs, so we plan to use COSMIN checklist to assess the risk of bias for both methodological quality of studies and PROMs included in those studies. Discrepancies will be resolved by discussion and/or involvement of a third reviewer. In addition, the strength of body of evidence will be assessed as high, moderate or low using Grading of Recommendations Assessment, Development and Evaluation guidelines.37

Dissemination

The findings of this review will be disseminated through peer-reviewed publications, conference presentations and included in the lead author’s doctoral dissertation.

Discussion

Potential limitations of this study relate to the inability of predicting the strength of the evidence from the systematic review, however we will try to overcome this limitation by following a rigorous methodology and capitalise on our team members’ expertise in knowledge synthesis.

This systematic review serves as a crucial step in the direction of integrating PROMs in paediatric clinical care. It will also reveal the extent to which PROMs were successful in affecting HRQOL, healthcare services utilisation, patient outcomes and quality of care for chronic diseases in paediatric population. Results of this review will guide healthcare policy and clinical care practices to incorporate paediatric patients’ perspectives to deliver patient-centred care.
