Assessment of Loneliness (ESTE II Scale) [24].

Percentage of patients who improve loneliness. The total score of the scale ranges between 0 and 30 and is obtained by adding the score of each of the items on the scale. There are 3 levels of Social Loneliness depending on the score obtained: Low → 0 to 10 points; Medium → 11 to 20 points; High → 21 to 30 points.

Quality-of-Life Assessment (EUROQOL-5D) [25].

Percentage of patients with improved quality of life. Percentage of patients with improved anxiety/depression. In each dimension of the EUROQOL-5D scale, the severity levels are coded 1 if the response option is “(I have) no problems”; with a 2 if the answer option is «some or moderate problems»; and with a 3 if the answer option is «many problems». The second part of the EUROQOL-5D provides a complementary score to the descriptive system of the self-assessment of the individual’s state of health, using a vertical VAS scale of 20 cm and millimeters, ranging from 0 (worst state of health imaginable) to 100 (best imaginable state of health). The combination of the values of all the dimensions generates a 5-digit number, with 243 possible combinations of health states, which can be used as profiles. The average quality of life is obtained, among all these combinations.

Main Caregiver Burden (Reduced Zarit Scale) [26].

Number of main caregivers with burden/not burdened in the initial and final evaluation. Number of main caregivers who improve their burden in the final assessment. The maximum possible score is 35 points. An equal result, or less than 17 points, would indicate that there is no burden, and a value bigger than 17 is the opposite.

Family satisfaction.

Satisfaction with the community intervention process. The satisfaction scale is conducted by a person other than the one who conducted the intervention process. It is conducted via a telephone survey of 8 items to the caregivers of deceased patients in which the caregiver responds to the survey by answering each of the questions with the scores: No, never (1), A few times (2), Sometimes (3), Quite a few times (4), Yes, always (5).
