Background Rheumatology Day-Care Hospital Unit (DHU) is defined as a hospital care for a few hours with the objective to do diagnosis, clinical trials and/or multiple test, patient education and treatments that cannot be done in the outpatient clinic, but which do not justify the complete stay in the hospital

Objectives Analyze the number of visits that one patient needs in the Rheumatology-DHU to learn the self-administration of a subcutaneous drug.

To evaluate if there are differences between the numbers of visits made in Rheumatology-DHU for the different drugs, and between the different age groups of the patients.

Methods All patients who were prescribed a subcutaneous drug (except denosumab) during the period January 2015 - December 2016 were referred to Rheumatology-DHU. The nurse gave instructions, she supervised the patient's learning and she decided if the patients needed a new control in Rheumatology-DHU.

The following data were recorded: sex, age, diagnosis, drug, number of visits each patient made in Rheumatology-DHU, reason for new visit to Rheumatology-DHU in patients who had already been discharged and adherence to treatment.

Results 101 patients were visited in Rheumatology-DHU (8 were referred twice for education of different drugs). 79 were women (78%) and 22 men (22%). Mean age (MA) of 65 +/- 17 years (SD).

A total of 238 visits were made in Rheumatology-DHU.

Adherence to treatment was 98.2%.

Six patients (5.5%) required a new referral to Rheumatology-DHU: 1 for poor adherence to treatment (ADA), 3 for skin lesions (2 MTX and 1 GOL), 2 supervise the treatment (1 CER and 1 MTX).

In 9% of the patients, the education was done to a reference person and not to the patient himself.

The number of visits in the Rheumatology-DHU were: 1 in 26 patients (MS of 66 +/- 19.6 years), 2 in 59 patients (MS 65 +/- 18); 3 in 13 patients (MS 64 +/- 13); 4 in 6 patients (MS 67 +/- 14); 5 in 2 patients (MS 68 +/- 17), 6 in 2 patients (MS 70 +/- 22), 9 in 1 patient (47 years).

We analyzed PTH and MTX groups (because they had the highest number of patients) and we observed that in the PTH group 82% required ≤2 visits, 18%> of 2 visits. Patients in MTX group: 77% ≤2 visits and 23%>2 education visits. There weren't significant differences between the two groups (p=0.576).

Conclusions Adherence to treatment in patients who are referred to Rheumatology-DHU to learn the self-administration of a subcutaneous drug is very high.

The new visits in Rheumatology-DHU for doubts or side effects were few.

Patients on PTH treatment, who were older, didn't require a higher number of visits or more new referrals to Rheumatology-DHU. Therefore, age is not a limiting factor for the right learning of patients.

The patient's education by nurse in Rheumatology-DHU is necessary for the right control of our patients
