Objective:

To assess the efficacy of music therapy in reducing anxiety in patients undergoing interventional technique (IT) in the Pain Unit (UD) of the University Hospital Sagrat Cor in Barcelona.

Material and method:

Quasi-experimental study with a control group, prospective, pre-and post-intervention, transversal, non-randomized. Approved by the Research Ethics Committee IDC Salud Catalunya. Study population: patients scheduled to perform IT in the UD. Inclusion criteria: > 18 years old. IT indication. Exclusion criteria: psychiatric disorder, inability to answer study variables. Intervention group: IT has been performed by randomly playing the chosen music, free of noise pollution. Control group: IT has been performed without music therapy.

The modified analog visual scale has been used as a measuring instrument to assess the level of anxiety.

Results:

80 patients (71.6 % women, mean age 66.7 (SD 14) years, 49.4 % average studies, 64.2 % pensioners). 60.5 % do not perform treatment with anxiolytics. 59 % have low back pain, caudal epidural block is performed. 33.3 % underwent interventional technique for the first time.

In the control group the value of intra VAS is 5.83 (SD 3.2) and in the music therapy group 5.0 (SD 2.2), this difference is not statistically significant (F = 1.614, p = 0.208). The same happens in the value of post-intervention EVA.

In the control group the value of post VAS is 3.7 (SD 3.3) and in the music therapy group 3.1 (SD 2.4), this difference is not statistically significant (F = 0.755, p = 0.387).

In the control group the value of the intra analog visual scale is 4.3 (SD 3.1) and in the music therapy group 3.0 (SD 2.0), this difference is statistically significant (F = 4, 83 p = 0.031).

In the control group the value of the post analog visual scale is 2.7 (SD 2.8) and in the music therapy group 1.3 (SD 1.5), this difference is also statistically significant (F = 7.427, p = 0.008).

81.5 % consider that they have received enough information about the interventionist technique and 18.5 % are satisfied.

95.1 % consider that the professionals have given him confidence and security and the remaining 4.9 % are considered satisfied.

Of those who have assessed (40 patients) if music has created a relaxed atmosphere, 80% are considered very satisfied and the remaining 20 % satisfied.

Conclusion:

Although pain is not significantly improved in the interventionist group, anxiety does in both the intra and post-IT phases.

Patients feel very satisfied about the information received and consider the confidence and security provided by professionals very satisfactory. In addition, the music therapy group considers, in general, the relaxed atmosphere created by the music.

Music therapy is an excellent therapeutic tool, easy to use, accessible and economical, which can be used as an adjunct in IT in the UD.
