Integrated Psychosocial Care in Intensive Care (IPS-Pilot): Protocol for the Systematic, Multimethod Development of a Complex Intervention (Phase A).

BACKGROUND

There is a high, co-dependent strain on health care professionals (HCPs), patients, and their relatives in intensive care units (ICUs), leading to long-term mental, physical, and occupational consequences. To date, there is no systematic intervention to address this growing problem.

OBJECTIVE

The aim of the IPS-Pilot (German: Integrierte Psychosoziale Versorgung; English: "Integrated Psychosocial Care") project is the development (phase A) and pilot testing (phase B) of an integrated and complex psychosocial care intervention for HCPs, patients, and their relatives in ICUs. This study protocol focuses on phase A. A separate protocol for phase B will be published later.

METHODS

A structured, multimethod approach was used to gather evidence from the target groups mentioned above on the needs, expected benefits, and necessary conditions for implementation. These methods included (1) a scoping umbrella review conducted by 2 researchers, who independently screened and selected reviews and meta-analyses in the field of needs and demands in the ICU setting, following the Levac framework; (2) web-based and face-to-face interviews and focus group discussions, which were coded independently by 2 researchers and analyzed using qualitative content analysis; the identified categories and codes were then quantified by (3) an online survey conducted with former ICU patients, their relatives, HCPs working in ICUs, and members of the general population. Synthesized results-complemented by the theories of Psychosocial Safety Climate and Conservation of Resources, as well as online and face-to-face stakeholder workshops-were used for intervention development, which was guided by the Intervention Mapping framework.

RESULTS

Through the 4 substudies, we aim to gain insights into the psychosocial needs of the aforementioned target groups. Intermediate analyses were conducted to develop both a model of the problem and a model illustrating how these needs can be effectively addressed through a psychosocial intervention that involves integrating a clinically trained psychologist into the HCP team. Data collection and analysis for the intervention development were completed by June 2024, including substudy 1 (n=104 included articles), substudy 2 (n=22 interviews and n=18 participants in focus groups), substudy 3 (n=237 survey participants), and substudy 4 (n=11, n=15, and n=20 participants in 3 consecutive workshops), with further analyses still ongoing beyond the scope of intervention development. The results of the substudies, as well as the final needs-based intervention design, will be published separately. These findings form the basis for the feasibility study (phase B), conducted from July 2024 to July 2025, during which the intervention will be implemented in randomly selected ICU wards and evaluated in terms of feasibility.

CONCLUSIONS

Phase B will assess the feasibility of the IPS intervention. The findings will be incorporated into the intervention design and serve as the basis for a future randomized controlled trial to evaluate its efficacy.
