Relevance and use of health policy, health systems and health services research for strengthening rehabilitation in real-life settings: methodological considerations.

Research on health policy, systems, and services (HPSSR) has seen significant growth in recent decades and received increasing attention in the field of rehabilitation. This growth is driven by the imperative to effectively address real-life challenges in complex healthcare settings. A recent resolution on 'Strengthening rehabilitation in health systems' adopted by the World Health Assembly emphasizes the need to support societal health goals related to rehabilitation, particularly to promote high-quality rehabilitation research, including HPSSR. This conceptual paper, discussed with the participants in the 5th Cochrane Rehabilitation Methodological Meeting held in Milan on September 2023, outlines study designs at diverse levels at which HPSSR studies can be conducted: the macro, meso, and micro levels. It categorizes research questions into four types: those framed from the perspective of policies, healthcare delivery organizations or systems, defined patient or provider populations, and important data sources or research methods. Illustrative examples of appropriate methodologies are provided for each type of research question, demonstrating the potential of HPSSR in shaping policies, improving healthcare delivery, and addressing patient and provider perspectives. The paper concludes by discussing the applicability, usefulness, and implementation of HPSSR findings, and the importance of knowledge translation strategies, drawing insights from implementation science. The goal is to facilitate the integration of research findings into everyday clinical practice to bridge the gap between research and practice in rehabilitation.

The Family Needs Questionnaire-Revised: a Rasch analysis of measurement properties in the chronic phase after traumatic brain injury.

PURPOSE: The main aim was to evaluate the measurement properties of the Family Needs Questionnaire-Revised (FNQ-R) in family members of individuals living with severe traumatic brain injury (TBI). METHODS: A total of 309 family members of individuals with severe TBI from Colombia, Denmark, Mexico, Norway and Spain participated. Rasch analysis of the FNQ-R and its 6 subscales was conducted. RESULTS: The Rasch analysis indicated a lack of fit of the 37-item FNQ-R to one single underlying construct of needs, and less than half of the items were invariant across the countries. Misfit of single items was revealed in the Need for Health Information, Need for Emotional Support, Need for Instrumental Support, Need for Professional Support and Need for Community Support Network subscales. Fit to the Rasch model was obtained after removal of misfitting items. The Involvement in Care subscale had too few items to be adequately assessed by the Rasch approach. CONCLUSION: The FNQ-R is a well-targeted instrument for assessing the unmet needs of caregivers regarding the need for health information, emotional support, professional support and a community support network after some scoring adjustment and the removal of misfitting items. Caution should be taken when comparing responses across countries.
