6. BRIEF RESUME OF THE INTENTED WORK
6.1INTRODUCTION
“Prevention is better than cure”
One the most common infections especially among women is an infection of the urinary tract. About
40% of women develop a urinary tract infection (UTI) at some point in their life. The condition is
uncommon in boys and young men. Serious consequences can occur if a urinary tract infection affects the
kidneys. Infections of the urinary tract are usually treated with antibiotics1.
Women are especially prone to urinary tract infection. This is due to the shortness of the female
urethra. A count of 100,000 bacteria per milliliter in a woman without symptoms indicates asymptomatic
bacteriuria. In addition, women are at particular risk of recurrent UTIs after menopause because of decreased
levels of oestrogen, which reduces the number of lactobacilli. Lactobacilli are 'friendly' bacteria that inhibit
the vagina of fertile women and prevent other bacteria from invading the urethra. Also, after menopause, the
mucous lining of the urinary tract 'thins out' and its ability to resist bacteria invasion is reduced2.
An infection of the urinary tract usually occurs when bacteria from the digestive tract attaches to the
outer opening of the urethra and begins to multiply. Most infections originate from a type of bacteria called
Escherichia coli (E. coli), which normally lives in the colon. However, other types of bacteria such as
Chlamydia and Mycoplasma can cause UTIs in both men and women, although these infections tend to
remain limited to the urethra and the reproductive system. The primary risk factor for developing a UTI is
gender. Simply, many women suffer from frequent UTIs. Women tend to get urinary tract infections more
often than men because bacteria can reach the bladder more easily in women. The urethra is shorter in
women than in men, so bacteria have a shorter distance to travel. The outer opening of the urethra is also
located near the rectum in women. Bacteria from the rectum can easily travel up the urethra and cause
infection3.
The sooner UTI symptoms are treated the better. Nearly 20 per cent of people who have a UTI will
have another, and 30 per cent of those will have yet another. Usually, the latest infection stems from a strain
or type of bacteria that is different from the infection before it, indicating a separate infection. It's impossible
3
to predict whether a urinary tract infection will strike again, however knowing what symptoms to be aware
of can help4.
Catheter-induced urinary tract infections are very common, and preventive measures are extremely
important. Catheters should not be used unless absolutely necessary and they should be removed as soon as
possible. Reducing the risk for infections during long-term catheter use, however, remains problematic. If a
catheter is required for long periods, it is best to use it intermittently if possible (as opposed to an indwelling
catheter). Doctors recommend replacing it every 2 weeks to reduce the risk of infection and irrigating the
bladder with antibiotics between replacements5.
The most important prevention measures of UTI are adequate education, patient compliance, the use
of appropriate catheter type and material, consistent catheterization technique and proper catheter care. Daily
hygiene is very important. A typical catheter is one that has been pre connected and sealed and uses a
drainage bag system. To prevent infection, advise the client to drink plenty of fluids, including 3 glasses of
cranberry juice a day. The catheter tube should be free of any knots or kinks. Clean the catheter and the area
around the urethra with soap and water daily and after each bowel movement. (Women should be sure to
clean front to back.).Wash hands before touching the catheter or surrounding area. Never disconnect the
catheter from the drainage bag without careful instructions from a health professional on strict methods for
preventing infection. Keep the drainage bag off the floor. Stabilize the bag against the leg using tape or some
other system. Since UTI is caused mostly by E. coli organisms, the various predisposing/associated factors
responsible for UTI, if present, have to be simultaneously investigated and treated6.
The long-term indwelling urethral catheter continues to be a major cause of morbidity in patients in
hospitals, nursing homes and home care. These hospital-acquired infections can increase hospital costs,
length of stay, and mortality rates. Many authorities have recommended that wherever possible, alternative
techniques should be considered for the management of patients with urinary retention or incontinence7.

6.2 NEED FOR THE STUDY
Women are significantly more likely to experience UTI than men because of the length of their
urethra - the longer the urethra, the more protection you have. In women the urethra is fairly short and
straight making it easier for germs to travel into the bladder. Nearly 1 in 3 women will have had at least 1
episode of UTI requiring antimicrobial therapy by the age of 24 years. Almost half of all women will
experience 1 UTI during their lifetime. Specific subpopulations at increased risk of UTI include infants,
pregnant women, the elderly, patients with spinal cord injuries and/or catheters, patients with diabetes or
multiple sclerosis, patients with acquired immunodeficiency disease syndrome/human immunodeficiency
virus, and patients with underlying urologic abnormalities8.
Catheter-associated UTI is the most common nosocomial infection, accounting for >1 million cases
in hospitals and nursing homes. The risk of UTI increases with increasing duration of catheterization. In no
institutionalized elderly populations, UTIs are the second most common form of infection, accounting for
nearly 25% of all infections9.
Urinary tract infections account for approximately 40 percent of all hospital-acquired
infections annually, with fully 80 percent of these hospital-acquired urinary tract infections attributable to
indwelling urethral catheters. It is well established that the duration of catheterization is directly related to
risk for developing a urinary tract infection (UTI). With a catheter in place, the daily risk of developing a
UTI ranges from 3 percent to 7 percent10.
Urinary tract infection is the most common non-intestinal infection in women worldwide. The
pathogens causing UTI are consistent across the globe. The pathogenesis of urinary tract infection involves
ascending infection with coliform bacteria colonizing the perineum in susceptible women (80–
90% Escherichia coli, 5–10% Staphylococcus saprophyticus with the remainder caused by Proteus and other
Gram negative rods).Lower urinary tract symptoms which accompany UTI include bothersome sensations
such as urinary urgency, frequency, painful urination, hesitancy, and the sense of incomplete bladder
emptying.
Most of these UTI are uncomplicated and managed on an outpatient basis with simple antibiotic
regimens. In low and middle income countries with reduced access to medical care, UTI may be expected to
cause more morbidity and incur greater risk of adverse outcomes when women are unable to get appropriate
treatments early in the course of disease. A total of 100 urine samples were collected and analyzed for the
5
presence of bacteria. 75 (75.0%) were found to be positive for bacterial UTI. The distribution of infection on
the basis of age revealed prevalence rates of 100.0%, 94.4% and 64.0% for age groups 30-39, 20-29 and 40-
49 respectively. The prevalence rates for the groups were found to be significantly high (P> 0.05). One
hundred and ten bacterial agents were isolated, characterized and identified. . Klebsiella spp showed the
highest frequency of occurrence of 43 (39.1%) and followed in descending order by Escherichia coli,
Staphylococcus aureus, Proetus vulgaris, Pseudomonas aeruginosa and Salmonella spp with 31 (28.2%), 23
(20.9%), 11(10.0%) 1 (0.9%) and 1 (0.9%) respectively. The study revealed a high prevalence of bacterial
UTI in the study area for all the age groups investigated. The result underscores the need for the
implementation of a control program in the area11.
The purpose of this study was to compare the incidence of urinary infection using clean intermittent
catheterization with the incidence of infection using sterile intermittent catheterization in patients
hospitalized with spinal cord injury who were not receiving prophylactic antibiotics. Forty-six patients were
assigned randomly to a clean (n = 23) or sterile (n = 23) study group. Catheterizations were done at least
every six hours. Infection was defined as bacteriuria greater than or equal to 100,000 organisms/mL or
greater than or equal to 10,000 organisms per mL with fever of 100 degrees F or greater. Results of urinary
dipslides were recorded daily. Twenty-eight subjects (60.9%) converted to greater than or equal to 100,000
organisms per mL. Method of catheterization was neither associated significantly with development of
greater than or equal to 100,000 organisms per mL. (X2[1,46] = .36, p = .55) nor with symptomatic
infections (X2[1,46] = .15, p = .70). Data support the use of clean intermittent catheterization under the
conditions used in this study, including the use of a sterile catheter each day and careful monitoring of
infection and technique12.
If the patient have any signs and symptoms of urinary tract infection that definitely is the
responsibility of the nurses to take all measures to prevent urinary tract infection. Hence, owing to the
detailed background mentioned above, it is in the interest of the investigator to compare the effect of sterile
versus clean catheter care technique for preventing catheter associated urinary tract infection and the risk of
its complications.

6.3 REVIEW OF LITERATURE
According to Polit and Hunglar, “Review Of Literature” is considered as an essential step of research
process. It involves systematic identification, location, scrutiny and summary of written materials that
contain information in a research problem13. The review is described as follows.
Literature related to the effectiveness of sterile and clean technique to prevent catheter related
UTI.
A comparative study was conducted in Nehru hospital, PIGMER, Chandigarh, on the effectiveness of
sterile versus clean technique for indwelling catheter care. A total of 53 subjects were studied, 27 subjects
were in group I (sterile technique) and 26 were included in group II (clean technique). A quasi-experimental
design was adopted and the tools for data collection comprised of identification data sheet, nursing
assessment tool to detect urinary tract infection (questionnaire, observational checklist, patient’s record sheet
and laboratory investigation proforma and indwelling catheter care procedures for sterile and clean
technique). Simple random sampling technique was used for assigning the subjects in intervention group I
and group II. Data analysis was done using independent t test and chi square tests. The findings of the study
are both the techniques were effective in preventing catheter associated bacteriuria was observed evidence by
X2 =1.17 d.f. 1p>0.05. It was concluded that both the techniques are equally effective if carried out
correctly14.
A comparative study on Povodine-Iodine versus savlon for precatheterization cleansing and association
of bacteriuria with duration of catheterization was analyzed in surgical ward at Kasturba Medical College
Hospital, Manipal. The study includes age groups of 19 years to 60 years were included in the period from
November 2005 to July 2006.The study group was divided into group “A” and “B”. Group “A” consists of
50 patients with 25 females and 25 males and Group “B” consists of 50 patients with 24 females and 26
males. Group “A” patients were directed to use Povodine-Iodine IP5% W/V (available Iodine 0.5% W/V)
(Wockhard limited, Aurangabad, India) and Group “B” was directed to savlon 1% (chlorhexidine IP 0.75%
and cotrimide IP 0.15%, Isopropile alcohol IP 0.04%, purified water QS) for precatheterization cleansing.
Urine cultures and urine analysis were carried out immediately after catheterization in the third day and fifth
day of insertion of the catheter, with a total of 3 samples from each patient. Findings showed that the females
in group “A” had higher rate of bacteriuria than males and 16% in group “B” using savlon as disinfectant for
precatheterization cleansing, developed bacteriuria15.

A comparative study was conducted in Yazd in Iran, rates of bacteriuria and UTIs when water and
povidone-iodine solution were used for periurethral cleaning prior to catheterization in women who had
indwelling catheters inserted prior to gynecologic surgery. A single-blinded prospective randomized trial
was performed. The sample for this study was 60 women undergoing inpatient gynecology surgery who
required urinary catheterization as part of their routine care and were expected to have their catheter in place
for 24 to 48 hours. Overall, 18.3% of the 60 subjects had bacteriuria at the time of catheter removal, but the
rates were not statistically significantly different in the water (20%) and povidone - iodine (16.7%) groups.
None of the subjects met the criteria (colony count greater than 105) for a UTI. The findings of the current
study, suggest that compared to water, the use of topical antiseptics for cleaning the peri-urethral area prior
to catheter insertion does not significantly reduce the incidence of bacteriuria and UTIs16.
A comparative study on sterile and nonsterile urethral catheterization in patients with spinal cord injury
was designed in Ortho-Rehab-Neuro Hospital Center, Jackson Memorial Hospital, Miami , FL 33136-1094,
USA to determine the effect of sterile and nonsterile intermittent catheterization on the incidence of urinary
tract infection (UTI) in patients after spinal cord injury. The study included 29 patients with neurogenic
bladder dysfunction treated with intermittent catheterization. One group of 14 patients was on sterile
catheterization; another group of 15 patients was on nonsterile catheterization. Prospective single centre
randomized controlled trial. The mean ages of patients in the non-sterile and sterile catheterization groups
respectively were 38 (SD +/- 22) and 34 (SD +/- 14). In the non sterile group 60% were men and 60% of
patients were tetraplegic with the remainder being paraplegic. In the sterile group 50% of patients were men
and 64% were tetraplegic with the remainder being paraplegic. 66 urinary cultures were taken from the non
sterile group and 56 from the sterile group. On a weekly basis, urine samples were obtained and analyzed. A
total of 122 urine samples were analyzed. The patients on sterile catheterization had a 28.6% UTI incidence;
the group using a nonsterile catheterization technique had a UTI incidence of 42.4%. 17
A comparative study of sterile versus non-sterile urethral catheterization in Kent and Sussex Hospital,
Tunbridge Wells, Kent. In a prospective study, 156 patients underwent preoperative urethral catheterization,
randomly allocated to 'sterile' or 'clean/non-sterile' technique groups. There was no statistical difference
between the two groups with respect to the incidence of UTI. There was a considerable cost difference
between the two groups, the 'sterile' method being over twice as expensive as the 'clean' method. Strict
sterility is not necessary in preoperative short-term urethral catheterization and is more expensive and time
consuming18.
A four-group experimental study was done with 97 adult patients who had urinary catheters over 2 days
in three ICUs between April and July 2008.The purpose of this study was to compare the catheter –
8
associated urinary tract infection (CAUTI) rates resulting from the use of four perineal care agents (soap-and
–water, skin cleansing foam, 10% povidone-iodine, and normal saline) among patients in intensive care units
(TCUs). The patients received one of the four perineal cares. Data collected included the incidence of
CAUTI at baseline (prior to perineal care) and 1 week , 2 weeks, and 4 weeks after beginning perineal care
the patients were divided into UTI and non UTI groups. The hazard ratio (HR) and 95% confidence intervals
were calculated by Cox’s proportional hazard analysis. The results shows that the cumulative incidence of
CAUTIs per 100 urinary catheter days were 3.18 episodes during 1 week with urinary catheter, 3.31 episodes
during 2 weeks, and 3.04 episodes during 4 weeks after beginning perineal care. Interval incidence of
CAUTIs per 100 urinary catheter days for soap-and-water was 3.15, 4.39, and 3.62 episodes during week
1,2, and 4 after beginning perineal care respectively.Interval incidence of CAUIs per 100 urinary catheter
days for skin cleansing foam was 1.92, 4.44, and 5.26 episodes during week 1, 2, and 2-4, respectively.
Interval incidence of CAUTIs per urinary catheter days for 10% povidone-iodine solution was 5.3, 1.54, and
0 episodes during week 1, 2, and 2-4, respectively. Interval incidence of CAUTI per 100 urinary catheter
days for normal saline was 2.36, 0, and 2.13 episodes during week 1, 2, and 2-4 , respectively and the
cumulative incidence of CAUTI per 100 urinary catheter days for soap-and-water was 2.36, 1.72, and 1.81
episodes during week 1, 2, and 4 after beginning perineal care, respectively. Kaplan Meier analyses showed
no statistical difference in the cumulative incidences of CAUTI by agents at 1 week (X2 by log-rank = 1.617,
p = .655), 2 weeks (X2 by log-rank = 2.238, p = .525), and 4 weeks (X2 by log-rank = 2.046, p = .563). There
were no statistical differences among the agents after controlling for age, antibiotic use, fecal incontinence,
consciousness, fever and diabetes, which are known risk factors of CAUTI in patients with indwelling
urinary catheters19.
An experimental study on two techniques for cleansing the periurethral area immediately prior to
catheterization in a randomized clinical trial of 436 women undergoing obstetric care. Both groups were
catheterized using what the authors described as clean technique. Specifically, nurses washed their hands
using a detergent-based hand cleanser, opened a sterile pack for catheterization, donned sterile gloves, and
inserted the catheter using a “no-touch” technique. (These techniques qualify as “sterile” based on CDC
criteria.) However, subjects were randomly assigned to undergo periurethral cleansing, using a chlorhexidine
solution or tap water. The main outcome measure of the study was bacteriuria, dichotomized as high
bacterial colony counts (>=10 6 CFU/ mL) versus low colony counts (<10 6 CFU/mL). Urine specimens
were obtained within 24 hours of catheterization or immediately before removal if the catheter remained in
place for less than 24 hours. Data were analyzed on an intention-to-treat basis. Seventy subjects (14%) did
not have complete data because a urine specimen was not obtained when the catheter was removed. No
9
statistically significant differences were found when the frequency of bacteriuria was compared between
subjects cleansed with chlorhexidine versus tap water20.
A comparative study on the effect of water vs. povidone-iodine solution for periurethral cleaning in
women requiring an indwelling catheter prior to gynecologic surgery. This study compared rates of
bacteriuria and urinary tract infections in 60 women randomized to periurethral area cleansing with water or
povidone-iodine solution prior to insertion of an indwelling urinary catheter. A urine specimen was collected
immediately before and 24 hours after catheter insertion. There were no significant differences in the rate of
bacteriuria or urinary tract infections in the water and povidone-iodine groups.21
A comparative study of sterile versus non-sterile urethral catheterization. In a prospective study, 156
patients underwent preoperative urethral catheterization, randomly allocated to 'sterile' or 'clean/non-
sterile' technique groups. There was no statistical difference between the two groups with respect to the
incidence of UTI. There was a considerable cost difference between the two groups, the 'sterile' method
being over twice as expensive as the 'clean' method. Strict sterility is not necessary in preoperative short-term
urethral catheterization and is more expensive and time consuming22.
A comparative study of clean and sterile technique in intermittent catheterization in the spinal cord
rehabilitation units in western Canada. Thirty-six patients with cervical spinal cord injuries requiring
intermittent catheterization by nursing staff were recruited. None had a previous history of voiding
dysfunction or urinary tract infections. They used randomized controlled design and the subjects were
randomized to either clean or sterile intermittent catheterization technique. Protocols for both clean and
sterile techniques were standardized and followed by nursing staff and caregivers. Primary outcome measure
was symptomatic urinary tract infection as diagnosed by urine culture > or = 10(5) colony-forming units/mL,
pyuria (> or =10 leukocytes on high-power field), and accompanying symptoms. A total of 189 urine
specimens from 36 subjects were cultured. Of the 36 subjects, 15 (43%) developed a symptomatic urinary
tract infection: 6/16 (37%) from the clean group; 9/20 (45%) from the sterile group (P> 0.05). Mean time to
onset for symptomatic urinary tract infection for the clean group was 3.0 (standard deviation (SD) 2.4) weeks
and for the sterile group, 3.6 (SD 1.3) weeks (P> 0.05). The most common urinary organisms at onset of
symptomatic urinary tract infection were Enterococcus species followed by Klebsiella. Clean intermittent
catheterization in the rehabilitation setting does not appear to place the patient with spinal cord injury at
increased risk for developing symptomatic urinary tract infection, and has significant cost and time saving
benefits for the health care system, as well as enhancing the transition for the patient from rehabilitation to
community23.
10
A comparative study on sterile water versus 10% povidone-iodine in periurethral cleaning prior to
urinary catheterization in children Objective is to compare urinary infection rate in children cleaned with
sterile water versus a 10% povidone-iodine before bladder catheterization. Prospective randomized
controlled study of children requiring bladder catheterization in the emergency department whose parents
consented to the study were randomly assigned to either of 2 groups, in which sterile water (the “sterile
water” group) or 10% povidone-iodine (the “10% povidone-iodine” group) was to be used for peri-urethral
cleansing prior to catheterization. Result shows the sterile water group had 92 patients and the povidone-
iodine group had 94. Most children (87%) were under 12 months of age. Urine cultures were positive in 16%
of children in the povidone-iodine group and in 18% in the water group. There was no significant difference
in signs and symptoms between the 2 groups. There was no significant association between solution
preparation and cultures on univariate regression analysis. The conclusion shows cleaning the periurethral
area of children with sterile water prior to catheterization is not inferior to cleaning with povidone-iodine24.
A comparative study on water versus antiseptic periurethral cleansing before catheterization among
home care patients. The purpose of this study was to compare the risk of acquiring symptomatic urinary tract
infections through the conventional practice of using 0.05% chlorhexidine gluconate (CHG) versus sterile
water for periurethral cleansing before insertion of an indwelling urinary catheter. A randomized controlled
trial was used, and subjects were randomly allocated to either the sterile water group or the 0.05% CHG
group. Urine specimens for culture were collected 4 times for each subject within 2 weeks. Seventy-four
urine samples were collected in 20 subjects (sterile water group, 8; 0.05% CHG group, 12). There was no
significant difference in colonization count between the 2 groups. In addition, none of the subjects in the 2
groups developed symptomatic bacteriuria. Using sterile water to clean the periurethral area before
catheterization among home care patients will not increase the risk for urinary tract infections25.
A comparative study on the effect of sterile versus clean reused catheters in intermittent
catheterization for bacteriuria. Monthly urine cultures were analyzed at the University of Alberta Department
of Medical Microbiology and Infectious Diseases to determine whether single-use sterile catheters and clean
technique reduced the incidence of bacterial colonization in those using long-term intermittent self-
catheterization. Thirty subjects with spina bifida, ages 3 years to 16 years, entered a crossover study with
random assignment to 6 months of sterile single-use catheters or clean reused catheters. Seventeen subjects
were catheterized by a parent or caregiver; 13 were responsible for self-catheterization and cleaning of the
catheters. Six months of descriptive data were also collected at Alberta Children's Hospital from a similar
group of subjects with spina bifida who used sterile catheters only. In the crossover group, 38% of all urine
cultures were positive regardless of whether sterile single-use or clean reused catheters were employed. The
other group using only sterile catheters had a 36% positive culture rate. No difference in positive cultures 11
was found between males and females or between children who catheterized themselves and children whose
parents catheterized them. The authors concluded that plastic urethral catheters may be reused26.
An experimental study on clean intermittent self-catheterization (CISC) for quadriplegic patients--a
five year follow-up in Royal Brisbane Hospital, Australia. The findings of clean intermittent self-
catheterization as a long term method of bladder management for 36 quadriplegic spinal cord injured
patients, primarily at C6/C7 level, who were taught CISC between 1983 and 1987.Success in CISC was
assessed by a mail survey, a telephone interview, and current sterile urine status. Twenty nine (81%) of 36
patients continued to use CISC after a mean discharge period of 2.9 years (p less than 0.001) with high levels
of acceptance. Rao's V discriminant analysis showed success in CISC was affected by the interval between
injury and initial self-catheterization (Canonical Correlation Co-efficient = 1.34). Results of urinalysis for
patients continuing CISC were obtained for 18 (62%) patients, 16 (88%) of whom had sterile urine.
Implications of these and other findings along with reasons for cessation of CISC are discussed27.
A prospective comparison of urinary tract infections a one-year prospective study was carried out
comparing short-term patient morbidity, infection rates, and bacterial organisms in 33 children with
meningomyelocele. Twenty-four of the children were treated with clean intermittent catheterization (CIC)
whereas nine children had an interstitial lung disease (ILD). A minimum of four cultures per year were
obtained on each patient. Patients maintained on CIC had 36.8% of their cultures positive for bacteriuria
whereas children with (ILD) had 61.8% of their cultures positive (P less than .001). The incidence of
bacteriuria associated with clinical signs and symptoms was similar in both groups. Four of 24 children
treated with CIC had sterile urine whereas none of the children with ILD were persistently free from
bacteriuria. Only five of 24 children receiving CIC had 50% or more of their cultures positive as contrasted
with seven of nine children with an ILD (P less than .01). Escherichia coli accounted for approximately one
third of organisms recovered from infected urine in both groups. Although the short-term morbidity
associated with both treatment modalities is similar, the incidence of asymptomatic bacteriuria in children
maintained on CIC is significantly less than in children with ILD. Whether this factor plays a role in
determining long-term morbidity is a subject for further studying patients treated with either clean
intermittent catheterization or urinary diversion28.
