When someone is blowing Shofar for a patient at a retirement home, is it preferable to gather a minyan for this mitzva?

Although in general it is better to perform a mitzva ‘Berov Am’ or with a significant group of participants, there is no essential need for having a minyan present for Tekias Shofar. (Nitei Gavriel 1: 45: 7). However, Mikroei Kodesh (p. 59) quotes the Meiri’s opinion that it is indeed preferable.
