Hypothesis : At hospital discharge for home, the medical prescription of ONS according to the official criteria of SSNC and the legal regulations (completed prescription according to health's insurance and homecare delivery) dictates the compliance of the patient and the reimbursement of the ONS.

Rationale : At hospital admission, patients with an acute or chronically impaired nutritional balance are at nutritional risk. These patients can be identified by the Nutritional Risk Score 2002 (NRS 2002). Oral Nutritive Supplements (ONS) represent the first line of nutrition intervention. ONS are frequently prescribed during the hospital stay, and should be continued or discontinued after the hospital discharge. This latter decision should be based on officials criteria, defined by the Swiss Society for Clinical Nutrition (SSNC). To allow ONS reimbursement according to the legal regulations, all required administrative actions should be completed at the time of ONS prescription until the end of the treatment.

Center : Geneva University Hospital (HUG), site of Cluse-Roseraie.

Design : Quality control prospective observational survey.

Population : Hospitalized adults patients with Oral Nutritive Supplements (ONS). Four hundred patients to be included.

Duration : Inclusion from April to December 2015 (9 months).

Hypothesis : At hospital discharge for home, the medical prescription of ONS according to the official criteria of SSNC and the legal regulations (completed prescription according to health's insurance and homecare delivery) dictates the compliance of the patient and the reimbursement of the ONS.

Aims : The primary aim is to document the existence of an ONS medical prescription during the hospitalization and at hospital discharge for home.

The secondary aims are to describe :

• NRS 2002 score when prescribing ONS during the hospitalization, at hospital discharge for home and one month after hospital discharge for home
• Indications for ONS prescription at hospital discharge for home according to the official criteria of SSNC
• Type of ONS prescription at hospital discharge for home
• Number of ONS consumed one month after hospital discharge compared to prescription at hospital discharge
• Timing of the discontinuation of the ONS treatment
• Reasons for stopping the ONS intake.

Methods : Included are all hospitalized adults patients with ONS prescription at the HUG. Excluded are patients with ONS delivery by a homecare before the admission at the HUG or patients refusing to consume ONS or patients with major disorders of consciousness (ex : dementia) or patients unable to consume ONS (ex : dysphagia, dysfunction of upper limbs, etc.) or patients refusing to participate to the survey.

At inclusion, the comorbidities will be assessed by the Charlson Comorbidity Index. ONS prescription and nutritional risk by the NRS 2002 score will be described at hospital and at hospital discharge for home. One month after hospital discharge for home, patient's compliance to ONS will be assessed as nutritional risk by the NRS 2002 score.

Statistics : Data will be presented as mean ± standard deviation or as numbers and percentages according to the relevance, and analyzed using Chi-squared test or unpaired t-test as required.

• Age > 18 years
• Hospitalization in medical and surgical wards of the Geneva University Hospital, site of Cluse-Roseraie
