Healthcare professionals' opinions, barriers and facilitators towards low-value clinical practices in the hospital setting.

To explore healthcare professionals' opinions about low-value practices, identify practices of this kind possibly present in the hospital and barriers and facilitators to reduce them. Low-value practices include those with little or no clinical benefit that may harm patients or lead to a waste of resources. Using a mixed methodology, we carried out a survey and two focus groups in a tertiary hospital. In the survey, we assessed doctors' agreement, subjective adherence and perception of usefulness of 134 recommendations to reduce low-value practices from local and international initiatives. We also identified low-value practices possibly present in the hospital. In the focus groups with professionals from surgical and medical fields, using a phenomenological approach, we identified additional low-value practices, barriers and facilitators to reduce them. 169 doctors of 25 specialties participated (response rate: 7%-100%). Overall agreement with recommendations, subjective adherence and usefulness were 83%, 90% and 70%, respectively. Low-value practices form 22 recommendations (16%) were considered as possibly present in the hospital. In the focus groups, the professionals identified seven more. Defensive medicine and scepticism due to contradictory evidence were the main barriers. Facilitators included good leadership and coordination between professionals. High agreement with recommendations to reduce low-value practices and high perception of usefulness reflect great awareness of low-value care in the hospital. However, there are several barriers to reduce them. Interventions to reduce low-value practices should foster confidence in decision-making processes between professionals and patients and provide trusted evidence.
