RESUMEN
INTRODUCTION: Patient safety is a high priority in the Danish health care system, including that hospital patients get the proper nutrition during their stay. A Nutrition Committee at Odense University Hospital is responsible for policy regarding nourishment at the hospital. If patients experience suboptimal treatment, i.e. improper nourishment, in the Danish health care system, they have the right to file a complaint. These complaints enable the improvement potentials based on the patients' first hand experiences. Therefore, our aim was to examine the nutrition complaint pattern and to get a deeper understanding of the context surrounding nutrition problems, allowing the extraction of learning potentials. METHODS: We analysed complaints submitted to Odense University Hospital between 2018 and 2022 using the Healthcare Complaint Analysis Tool. The complaints were categorised into categories, levels of severity and overall patient harm. The complaints containing a high-severity nutrition problem were read through and thematised into aspects not defined in the Healthcare Complaint Analysis Tool. RESULTS: Between 2018 and 2022, 60 complaint cases containing 89 nutrition problems were filed to Odense University Hospital. Most (58.3%) of these were filed by the patients' relatives. The nutrition problems were mostly of low severity (56.2%), while 23.6% were severe, and 20.2% were very severe. The reading of 18 very severe nutrition complaints revealed a cascade of problems triggered by the nutrition problem in six cases. Moreover, we saw that two high-severity nutrition problems led to catastrophic harm. DISCUSSION: A low proportion of nutrition problems may express an underestimation regarding nourishment at the hospital. A patient's threshold may not be exceeded by suboptimal nutrition and therefore does not file a complaint. However, complaints contain important insights contributing to wider learning, given that improvements at the hospital so far are based on clinicians' reporting, overlooking the patient perspective.
