nrelieved postoperative pain

remains a common problem

despite advances in pain

management. Lack of sleep, often

caused by environmental noise in

hospitals, can contribute to irritabili-

ty, anxiety, and increased pain.

While analgesia is capable of modify-

ing many of the pathophysiological

responses to pain (Layzell, 2008),

pain in the postoperative patient is

of ten unre l ieved. Complementary

music therapy can create a distrac-

tion ftom pain, anxiety, worry, and

sadness, thereby increasing patient

satisfaction with the postoperative

experience (Koelsch, 2009).

Background

Our Lady of the Lake Regional

Medical Center (OLOLRMC) is a

M agne t®-d esigna ted, DAISY® Hos-

pital Partner with surgical volume of

11,270 cases annually. Postopera-

tively, patients are admitted primari-

ly to the inpatient surgical unit

(SURG). SURG is a 27-bed inpatient

uni t with two wings (A ha ll= ll beds;

B hall=1 6 beds) . Its staff ma nag es

care of patients after planned surgi-

cal procedures, predominately ab-

dominal , vascular , and oncology

diagnoses. In fiscal year 2010, 2,191

patients were discharged ftom SURG

with an average length of stay of

3.57 days.

Theoretical Model

As part of the professional model

of care at OLOLRMC, principles

inherent to Relationship-Based Care®

Postoperative pain is difficult to m anage with analgesia alone.

Com plementary interventions such as music therapy provide a level o f

distraction thus prom oting com fort. In this study  decreased  pain and

environmental noise were demonstrated without diminishing state

  nxiety in a group of postoperative patients.

(RBC) delivery model supported the

study. Three crucial relafionships in

RBC include care of  self care of col-

leagues, and care of patients and fam-

ilies.  Nurses convey caring and com-

passion thro ugh touch, kindness, clin-

ical interventions, active listening,

and und erstandin g of the pafient s

experience (Koloroutis, 2009). The

purpose of this study was to deter-

mine if the use of music therapy was

an effective adjunct to decrease state

anxiety while increasing pain man-

agement and environmental noise

satisfaction in the postoperative

pafient.

Research  or  ractice

Introduction

Unrelieved postoperative pain remains

 a

 com mo n p roblem despite advances

 in

pain management. Complementary music has been suggested as an adjuvant

 to

the standard

 of

 care treatm ent fo r postoperative

  pain.

Purpose

The purpose of this s tudy was to determine if  music therapy was

 an

 effective

adjunct to decrease state anxiety,  and increase pain m anagem ent and environ -

mental noise satisfaction

 in

 the postoperative patient.

Method

A quasi-experimental non-equivalent control group design was used

 in

 this study

with participants assigned based

 on

  room assignment rather than randomly. The

control group, which consisted of participants admitted  to the A hallway, received

the standard of care.

 The

 intervention grou p, wh ich consisted of  participants

admitted

 to

 the B hallway, received comp lemen tary music therapy

 in

 the form

 of

pre-programmed MP3 players, in addition  to the standard  of care. Based  on the

premise

 of

 a non-equivalent c ontrol design, neither analgesia ty pe

 nor

 route was

controlled.  Each participant was enrolled

 for

 a total

 of

 3

 days

 or

 until discharge,

whichever came first. Outcome measures were collected upon enrollment (Time

One) and for the next 2 consecutive days (Time Two and Time Three). Participants

in

 the

 intervention group were encouraged

 to

  listen

 to a

 selection

 of

  non-lyrical

low decibel (less than

 60 db

pre-programmed music,

 for at

 least

 30

 minutes via

a

 MP3

 player after their prescribed analgesia was adm inistered . Non-lyrical

 low

decibel m usic was chosen for  this study because previous research supported  its

effectiveness. State trait anxiety as well as pain and environmental noise satisfac-

tion were assessed using

 the

  State-Trait Anxiety Inventory and

 two

 standardized

questions f ro m the Press Ganey® survey.

Findings

Before the intervention was implemented, both groups were the same related

 to

their average level

 of

 state  and  trait anxiety,

  pain,

 and  noise perception. The

patient s state anxiety, pain perception ,

 and

  noise perception were measured 

day after

 the

  intervention was

 in

 place.

 A

  significant difference was found from

Time One to Time Two in pain managem ent (t=3.938,  p<0 001 ) and environmen-

tal noise satisfaction (t=3.457, p=0.001), while there was

 no

 change

 in

 state anx-

iety (t=0.373, p= 0 .7 n ). The intervention group experienced improved pain man-

agement (t=7.385, p<0.011)

  and

  environm ental noise satisfaction over tim e

(t=4.371; p<0.001); however, there was no improvement in state anxiety (t=1.47;

p=0.159). The findings suggest music therapy decreases pain and environmental

noise perception, although there was

 no

 effect on state anxiety.

Conclusions

Use of music therapy improves patients postoperative experience

 by

 increasing

their pain ma nagem ent and w hite noise satisfaction. Because the intervention w as

tested on a busy post-surgical unit with  a  short inpatient stay (mean=3.57),  the

effect

 of

 music therapy over more than

 2

 days could not be m easured. This inter-

ventio n was inexpensive a nd easy

 to

 implement

 in

 the clinical setting, and the re-

fore recommended

 to

 improve postoperative outcom es in othe r facilities.

 It

 is rec-

om me nde d the study be replicated wit h a larger sample size and different p atient

populations

 to

 validate these findings .

increased postoperative morbidity,

delayed recovery and return

 to

 nor-

mal daily living, and reduced patient

satisfaction (Macintyre, Schug, Scort,

Visser,

 

Walker, 2010).

  ffect

 of

 Music Therapy

Research indicates music therapy

provides distraction, promotes relax-

ation, and decreases anxiety (Engwall

 

Duppils, 2009). Music therapy has

a beneficial effect

 on a

 patient's per-

ceived pain, relaxation, respiratory

rate,

  self-reported anxiety level,

 and

the amount

 of

 analgesia required

 for

eftective pain management (Ameri-

can Music Therapy Association,

2010).  When used

 in

  conjunction

with pharmacologie pain manage-

ment strategies, music therapy pro-

motes

 a

 sense

 of

 well-being

 and an

overall positive patient experience

(Walworth, Rumana, Nguyen,

 

Jarred, 2008). While music therapy

has

 the

 propensity

 to

 promote

 dis-

traction

  and

  relaxation, limited

research has focused on the effective-

ness

 of

 music therapy

 for

 pain m an-

agement

  in

  postoperative patients

outside

  a

  controlled environmen t

Goanna Briggs Institute, 2009).

Relationship hetween Pain

and nxiety

Postoperative pain, while

 an ex-

pected consequence

  of a

  surgical

procedure,

 is

 infiuenced

 by

 psycho-

logical factors, such as fear and anxi-

ety (Engwall

 

Duppils, 2009).

  Be-

cause trait anxiety inherently is indi-

vidualized

 and

 aftects

 the

 ability

 to

address

 a

  perceived threat, persons

wit

heightened anxiety may experi-

ence more postoperative pain than

those who are less prone

 to

 anxiety

(Lin, Lin, Huang, Hsu, Lin, 2011).

Conversely, patients with

  low

 trait

anxiety may

 be

  more pain tolerant

than those with high trait anxiety.

Researchers recommend interven-

tions should

  be

  stratified based

 on

the participant's trait anxiety score

(Binns-Turner, 2008; Nilsson, 2008).

Contrary

 to

 trait anxiety, state anxi-

ety refers

 to

 feeling nervous

 or

 anx-

ious when faced

  vnt an

 imm ediate

danger

  or

  stressful situation.

  It is

transient, fiuctuates over time,

 and

varies in intensity (Lin et al., 2011).

The Effect of Complem entary Music Therapy on the Patient's Postoperative State Anxiety, Pain C ontrol, and Environmental Noise Satisfaction

Environmental Noise

Reduction

Environmental noise  is a  signifi-

cant barrier  to  sleep for  hospitalized

patients; research supports sleep

  as

therapeutic

 to

  overall health, wound

heal ing,  and  recovery (Gardner,

Col l ins, Osborne, Henderson, 

Eastwood, 2009). Noise  in and

around

  the

  nurses' station

  can be

especially problem atic (Haupt, 2012).

Music therapy functions  as a dis-

tracter ftom hospital noise, thereby

reduc ing emot iona l anx ie ty  and

pain (Gardner

 et al.,

 2009).

 To pro-

m ote relaxation, music should: (a) be

non-lyrical,  ti) have predom inant ly

low tones,  (c)  have m inima l brass

and percussion,

 and (d)

  have

 a

 max-

imum dec ibe l vo lume

  of 60 db

(Nilsson, 2008).

Purpose and ypothesis

The purpose  of  this study was to

determine the eftect  of  music thera-

py  on  state anxiety, postoperative

pain,  and environm ental noise per-

cep t ion .  The  hypo thes i s  for  this

study was as  follows: Music therapy

will decrease state anxiety, increase

pain management eftectiveness,

 and

increase environmental noise satis-

faction in postoperative patients.

Method

The first 41 data sets collected to

test the efficacy and feasibility of the

study methods  are  reported here.

The larger study, which is still o ngo -

ing, consists of three grou ps: (a) con-

trol, (b) music the rapy, and (c) wh ite

noise therapy.  The  pilot study and

the larger s tudy were provided

exempt status  by  bo th  the  Nursing

Research Council  and  Clinical Re-

search Steering Co mm ittee of OLOL-

RMC.  An

  implied con sent process

was used because  a wriften consen t

would have t ied  the  participant  to

the study, thereby precluding

exempt criteria definition. Providing

complementary music therapy

  via

pre-programmed  MP3  players  was

an inexpensive intervent ion that

was implemented easily to  enhance

the patient's postoperative experi-

ence.

Sample and Setting

All patients adm itted to the surgi-

cal unit

  who met the

  following

inclusion criteria were asked

 to par-

ticipate in the  study: anticipated 3-

day hospital length of stay, alert and

oriented, age  18 or older, able to read

and write English, and hematology-

oncology diagnosis . Par t ic ipants

were  not  assigned randomly to the

in tervent ion  but  rather placed into

groups based on the  hallway assign-

me nt. P articipants admifted  to the A

hallway received the standard of care

(control group), while participants

admifted

  to the B

 hallway received

complementary music therapy  (in-

terve ntion group) (see Table 1). Both

groups received the provider-ordered

analgesia. Participants  in the  inter-

vention group were encouraged  to

listen  to a  selection  of  non-lyrical

p re -p rogrammed music  via MP3

players for 30 minutes following the

administration

  of

  prescribed analge-

sia. Each participant was enrolled

 in

the study  for 3  consecutive days

(Time

 One,

 Time Two, Time Three)

or until discharge, whichever came

first.

  e sures

The State-Trait Anxiety Inventory

(STAI)

 was

 used

 to

  evaluate anxiety.

The STAI is divid ed in to the two sub-

scales: STAI Form  Y-1 and STAI F orm

Y-2.  The  20-item STAI Form  Y-1

(Chronb ach's a lpha = 0.62) was used

to m easure state anxiety (Spielberger,

Gorsuch,  Luschene, 1970). The

STAI Form

  Y-1

  (range score 20-80)

measures  the  participant 's current

emotional feeling, such  as  calm  or

nervous. Participants rated  the de-

gree  to  which  the  item represented

how they  currently felt  using  a 4-

po int Likert scale ranging ftom not at

all to  very much so,

 with

  the

  higher

score indicating greater state anxiety

(Spielberger et al., 1970).

The 20-item STAI Form  Y-2

(Chronbach's alpha = 0.86) was used

to measure trait anxiety.  The  STAI

Form

 Y-2

 (range score

 of

 20-80) mea s-

ures participants' usual emotional

feelings, s uch as feelings of  inadequa-

cy  or  happiness (Spielberger  et al.,

1970). Parücipants rated  the  degree

to which

  the

  item represented

 how

they  generally felt  using  a  4-point

Likert scale with responses ranging

ftom   almost never to  almost always;

the higher score indicated higher

trait anxiety (Spielberger

 et

 al., 197 0).

Two standardized items concern-

ing patient satisfaction, which were

developed and used extensively by a

national vendor, measured  the par-

ticipant's satisfaction with pain man-

agement  and  environm ental noise.

Participants were asked to  rate each

item:

  (a)

  During

  the

  previous

  24

hours,  I am  satisfied with  my  pain

control, (r2 = 0.72)  (Press Ganey,

2010) and (b)  Dur ing the previous

24 hours,  I am  satisfied with  the

noise level in and a round my r o o m

(r̂  = 0.74) (Press Ganey, 2 010), on a

4-point Likert scale ranging ftom  1

  no t  t

 all

to 4

 {very

 much so), with a

higher score indicating greater satis-

faction.

Findings

At Time One, no significant dif-

anxiety, or pain management or

environmental noise satisfaetion

between groups (see Table 2). The

partieipant s state anxiety, pain ma n-

agement satisfaetion, and noise satis-

faetion were measured again 1 day

after the intervenfion was in plaee

(Time Two). At Time Two, a signifi-

eant inerease was found in pain

management (t=3.938; p<0.001) and

environmental noise satisfaetion

(t=3.457; p=0.001), while n o ehange

was found in state anxiety (t=0.373;

p=0.711)(seeTable3).

The efteetiveness of the interven-

fion was analyzed over time. For the

eontrol group, no difterenee existed

in state anxiety (t=0.149; p=0.883),

pain m anagem ent (t=0.237;p=0.815),

or environmental noise (t=0.568;

p=0.576) satisfaetion ftom Time One

to Time Two (see Table 4). The inter-

vention group experieneed a signifi-

eant improvement in pain manage-

pain and environmental noise satis-

faction indicated participants gener-

ally were not satisfied with pain.

management or with noise levels in

and around their rooms. During the

Time One measurement, all partici-

pants reported being only somewhat

satisfied with pain m anagem ent over

the previous 24 hours (music group

li=2.42;

  control group ]i=2.74), sug-

gesting participants were not satis-

fied with the standard of care alone.

At Time One, environmental noise

satisfaction was slightly higher in

the control group (p=3.14) than w ith

the music group (p=2.74). The differ-

ence in noise perception can be

attributed to renovations on the A

hallway, placing the bed behind a

double wall, further away from the

doorway, along with the installation

of acoustic tiles in each room .

The difference between groups at

Time Two revealed no significant

change in state anxiety (t=0.373,

p=0.711), suggesting music therapy

did not decrease situational anxiety

levels as previously predicted. Be-

cause the majority of the patients on

this un it had surgical oncology diag-

noses,

  the lack of relationship bet-

ween music and state anxiety may

be understandable. Results of this

study partially supported the hypo-

thesis that music therapy is effecfive

as a non-pharmacological adjunct to

analgesia in increasing pain m anage-

ment and environmental noise satis-

faction; however, state anxiety re-

mained unchanged.

Nursing Implications

In th is study, use of musi therapy

improved pain management and

environmental noise satisfaction

when used as a com plementary ther-

apy. Therefore, distraction from neg-

ative experiences through use of

music therapy can increase satisfac-

tion in patients recovering from sur-

gery. This interv ention was inexpen-

sive and easy to implement in the

clinical setting, and therefore recom-

mended for use to improve postoper-

ative outcom es. MP3 player techno l-

ogy decreased in cost, providing a

viable option for hospitals. The play-

ers can be cleaned easily, patients

can be given their own ear buds to

keep,

 and music discs are a one-time

purchase. Nurse leaders may consid-

er purchasing MP3 players inscribed

with their hospital logo for the

patients to keep, thus promoting the

intervention after discharge.

Findings ftom this study can be

incorporated easily in to the nurse s

practice. The medical-surgical nurse

could encourage family members to

bring the patient s favorite music

ftom home to augment analgesia.

Portable CD players, MP3 players,

and cell phones are all viable por-

table options to provide music.

Family members also should be

reminded to bring earphones or ear

buds to prevent disrupting other

patients. The nurse can encourage

the patient to listen to the music

immediately after analgesia adminis-

tration for a period of at least 30

minutes. Not only will the patient s

favorite music decrease anxiety, but

it also masks routine hospital noise

that patients often find annojáng.

Limitations and

Recommendations for

Future Research

Preliminary analysis identified

some limitations in the study. First,

patients were not assigned random-

ly to the intervention; although

room assignments were non-predic-

tive, they were not random . In addi-

tion, use of personal distraction may

have confounded the findings of

this study. Patients in the control

group also reported listening to

music. Patients may have brought

their own music with them or lis-

tened to music provided on the tel-

evision network. Because no manip-

ulation occurred to change usual

care, some unanticipated crossover

eftect m ay have o ccurred. While th e

sample size is small, the significant

difference observed may have

occurred by chance; however, find-

ings ftom the larger study support

the findings reported here. The

study should be replicated with a

larger sample size and w ith difterent

patient po pulations to validate these

findings. Data collected at Time

Three were limited due to the unit s

average length of stay or partici-

pants failure to complete the ques-

tionnaire on the day of discharge.

The

 ST I

 Qu estionnaire was tedious,

somewhat repetitive, and upsetting

for some, especially those with new

cancer diagnoses. Beginning the

intervention earlier in the preopera-

tive period also may be helpful so

the patient could benefit ftom the

intervention through the surgical

experience and hospitalization.

Conclusion

Findings of this study suggest

music therapy improves the postop-

erative experience through en-

hanced pain management and envi-

ronmental noise satisfaction. The

intervention was inexpensive and

easy to imp lement in the clinical set-

ting, and therefore is recommended

for use in improving postoperative

outcom es in other facilities.
