● Higher dependence in performing basic and instrumental activities of daily living increases the risk of pressure ulcer.
● Basic activities of daily living is more important than instrumental activities in the development of pressure ulcer.
● All subscales of basic and instrumental activities of daily living are associated with the development of pressure ulcer.
●The degree of dependence in basic and instrumental activities of daily living can be one of the predictors of pressure ulcer development.
Plain Language Summary
Daily living activities like bathing, dressing, and instrumental daily activities like shopping or housekeeping decrease the risk of bed sore. It is particularly important in patients aged above 45 years with chronic diseases. The degree of dependence in daily activities can be one of the predictors of bed sore development. Therefore, in the field of education, it is necessary to hold training classes and methods for nursing staff in order that they teach empowerment techniques to their patients. Also training programs for patients, public community, especially older people should be held with respect to strategies for increasing their independence. Family members of at-risk patients should plan appropriately to increase the independency of the patients in performing such activities. Most importantly, patients who are at risk must try to manage their activities independently as far as they can.

1. Background
According to The National Pressure Ulcer Advisory Panel (NPUAP), Pressure Ulcer (PU) is defined as a local damage to the skin and its underlying tissues. It usually develops around bony prominences because of pressure or combination of pressure and friction (Amirifar et al. 2013). Pressure ulcer is a significant index of poor quality of patient care and one of the most crucial challenges encountered in the current health and medical treatment (Seong-Hi & Lee 2016). Health care team staff spend a lot of time and energy managing the physical, emotional, and economic challenges of treating this disease (Mehrabani, Hosseini & Karimloo 2012). About 10% of hospitalized patients and 5% of community-living patients have varying degrees of PUs. In a review study of Karimian et al. On 5973 patients in Iran during 1998-2015, the incidence of PUs among hospitalized patients was reported as 19% (Karimian et al. 2016)
About 95% of the pressure ulcers can be prevented (Fu Shaw et al. 2014), and nursing staff are responsible for direct care and ongoing prevention and treatment of pressure ulcers (Miyazaki, Caliri & Santos 2010). Thus, in clinical care, the main emphasis is on awareness and understanding of the risk factors for PUs and appropriate preventive interventions (Coleman et al. 2013). Prevention of PUs is a priority in nursing care and a key indicator of nursing care quality (Soozani et al. 2012). General evaluation and in particular, risk assessment, is an essential part of nursing care (Dijkstra, Kazimier & Halfens 2015). In the evidence-based guidelines for PU management, risk assessment is the most important issue (Balzer et al. 2014). Physical inactivity and lack of movement are considered the main cause of PU (Chaboyer et al. 2015)
The concept of daily living activities is often used to determine the level of self-care (Hilgenkamp, Van Wijck & Evenhuis 2011). Daily living activities are defined as activities that a person normally performs on a daily basis to run an independent life (van het Bolscher-Niehuis et al. 2016). The Roper-Logan-Tierney Model for Nursing is a theory of nursing care introduced in 2000 based on Activities of Daily Living (ADL). It includes the biophysical activities needed to sustain life and activities that increase the quality of life. This model helps determine the measures needed for those who are physically or mentally dependent or unable to perform activities. In this regard, it helps nurses to plan and apply the care processes needed for patients to prevent secondary complications such as PUs (Aydın & Mucuk 2015). 
Activities of daily living are divided to Basic Activity of Daily Living (BADL) such as bathing and grooming, and Instrumental Activity of Daily Living (IADL) such as shopping and money management (Seitz et al. 2014). Nurses as health care professionals have an important role in determining the care needs of patients, and they must be sure that the patients perform their ADLs at the highest possible level (Cerit 2014)
Natural changes due to aging, acute illness, exacerbation of chronic diseases, and hospitalization can reduce the ability of individuals to perform ADLs (Graf 2013). Caring plans involve continuous assessment by nurses to regain the performance and prevent further reduction through actions such as using physical or occupational therapies, if needed (Wallace & Shelkey 2008).
Because of the multifactorial nature of the PU, effect of various factors on its incidence, and consistent with the Braden scale, researchers are highly interested in investigating all the factors associated with its creation and how they enhance the prediction of PU (Raju et al. 2015). In particular, those who are not active, have a poor sensory function and cannot perform their ADLs well are at higher risk of developing PU (Mostoufian 2015). Since the development of a PU is multifactorial and poorly understood, systematic monitoring of its incidence, risk assessment and preventive measures are essential (Raju et al. 2015). In addition, the extent of dependency to other family members may prepare the ground for development of PU.
The current study aims at investigating the relationship of BADL and IADL with the risk of developing PU among patients referred to teaching hospitals affiliated to Iran University of Medical Sciences (IUMS) in 2016. The results may help nurses and families make proper planning to increase the independency of these patients.

2. Materials and Methods
It is a descriptive, cross-sectional study. Research population consists of all patients referred to medical and surgical clinics affiliated to Iran University of Medical Sciences in 2017. The sample included patients aged above 45 years with rheumatoid, endocrine, cardiovascular, and pulmonology diseases referred to medical clinics and also patients with neurologic and orthopedic diseases referred to surgical clinics. 
The sample was recruited using convenience cluster sampling method; the clusters were each teaching centers of Firouzgar and Rasool-e-Akram hospitals. Sampling from these hospitals was done in equal proportions. The sample size was calculated as 200 based on 95% confidence level, 80% test power, and assuming that the correlation coefficient of BADL and IADL with the risk of developing PU should be at least 0.2 (to have a statistically significant relationship between them).
Data collection tool was a Persian-language questionnaire having four parts that was completed by the researcher. Part one surveys demographic characteristics, including gender, age, diagnosis, education level, weight, height, body mass index, presence or absence of pressure ulcer, degree and location of pressure ulcer if any, use or non-use of air mattresses, presence or absence of disability and underlying diseases, number and type of underlying diseases if any, and specific drug use. Part two includes Katz Index of BADL which assesses six subscales: Bathing, dressing, toileting, transferring, continence, and feeding. Each subscale is scored from 0-1.
A score of 6 indicates full independency, 3-5 moderate dependency, and 2 or less indicates severe dependency. Part 3 contains Lawton IADL Scale, which evaluates eight functions: Ability to use telephone, shopping, food preparation, housekeeping, laundry, mode of transportation, responsibility for own medications, and ability to manage finances. Patients are scored according to their highest level of functioning in that category. Score ranges from 0 (low function, dependent) to 8 (high function, independent) for women, and 0 through 5 for men. Finally, Part 4 includes Braden Scale for predicting pressure ulcer risk by examining six subclasses: Sensory perception, moisture, activity, mobility, and nutrition rated on a scale of 1 to 4, and friction and shear subscale rated on a scale of 1 to 3.
The total score ranges between 6 and 23. Higher score indicates a lower risk of developing pressure ulcer and vice versa. Based on this scale, pressure ulcer risks are divided into five groups: Very high risk (total score 9 or less), high risk (total score 10-12), moderate risk (total score 13-14), mild risk (total score 15-18), and no risk (total score 19-23). 
To determine the reliability of the screening tools, after explaining the process to the caregivers or the patients, the first examiner completed the questionnaires through interview with the patients. After an interruption on the same day, the second examiner completed them again. The agreement between two examiners were tested by measuring the interclass correlation coefficient which were reported 0.959 for Katz Index, 0.963 for Lawton IADL scale, and 0.983 for Braden Scale.
The collected data were analyzed in SPSS-PC V. 24. Descriptive analyses were done by calculating percentage, mean, standard deviation, and frequency distribution tables. With regard to inferential statistics, Kolmogorov-Smirnov test was used for testing the normality of data distribution. The results indicated that all three variables of BADL, IADL, and pressure ulcer risk were normally distributed.
The Independent T test, ANOVA, and Tukey’s Test were used for examining the relationship between demographic characteristics and the mean pressure ulcer risk score. Next, the Pearson correlation test was done for examining the correlation of BADL and IADL scores with pressure ulcer risk score. Finally, the Spearman correlation test was employed for assessing the correlation between the BADL and IADL subscale scores with pressure ulcer risk score.

3. Results
Based on the results, more than half of participants were male (55%). The mean age of the participants was 61.96 years. In terms of educational level, 54% of the participants had a high school diploma and 46% were illiterate. The mean weight of participants was 75.5 kg, while their mean height and Body Mass Index (BMI) were 165.14 cm and 27.73 kg/m2, respectively. 
The most involved system was the neurological system (28%). About half of the participants had underlying disease (45.5%). Of the participants with underlying disease, 65.94% had one underlying disease. Among the underlying diseases, high blood pressure (24%) and diabetes (10.5%) had the highest incidence. Seven percent of participants had disabilities, and 35.5% were under specific medications, including non-steroidal anti-inflammatory drugs, beta-blockers, blood diluents, inotropes, chemotherapeutic and radiotherapy drugs. Seven percent of the participants had pressure ulcers, and 78.5% of the pressure ulcers were grade 1. None of the participants had grade 3, 4 or ungradable ulcers. Furthermore, 42.8% of the pressure ulcers were observed in sacral region and 35.7% in the buttocks. None of the patients used air mattresses (Table 1).
According to the findings, 66% of the subjects were independent in performing BADL, while 22% were moderately dependent and 12% dependent. The mean BADL score was reported 5.08. In performing IADLs, 17.5% were dependent, 41.5% moderately dependent and 41% were independent. The mean IADL score was 5.65 (Table 2). 
According to the Braden scale, 2.5% were at high pressure ulcer risk, 3.5% at moderate risk, 10.5% at mild risk, and 83.5% at no risk. None of them was at very high pressure ulcer risk status (Table 2). The mean score of PU risk was 20.45. According to the results in Table 3, higher dependence in performing BADLs (r=0.720, P<001) and IADLs (r=0.741, P<001), increased the risk of developing pressure ulcers, also the effect of IADLs was higher than BADLs.
Age, underlying disease, disability and drug use had a significant positive relationship with the risk of developing pressure ulcers (P<0.001). The results of Tukey’s post hoc test showed that patients over the age of 70 were at higher pressure ulcer risk compared to other age groups (P<0.01). There was a significant and negative relationship between educational level and the risk of developing pressure ulcer (P<0.001). Patients with a high school diploma or higher degree education were at lower risk of developing pressure ulcers (P<0.01) compared to lower levels of education. There was no statistically significant relationship between variables of “gender” and “BMI” with pressure ulcer risk (P<0.05). Since none of the participants had used air mattresses, the relationship between this variable and the pressure ulcer risk was not examined (Table 3).
Dependence in all subscales of BADL and IADL had a significant relationship with pressure ulcer risk (P<0.01), where dependence in transferring (r=0.685) and toileting (r=0.626) as BADLs, and housekeeping (r=0.687) and mode of transportation (r=0.591) as IADLs showed higher correlation (Table 4). 

4. Discussion
Many pressure ulcers are reasonably preventable through evidence-based care, but prevention requires knowledge of the associated factors with pressure ulcer development (Bergquist-Beringer & Gajewski 2011). The results of the current study showed that most participants were independent in their BADL performance, but moderately dependent in performing their IADL. 
In the study of Bourne (2009), most subjects were independent in performing BADL and IADL. Our results and Bourne’ were the same in BADL part. The disagreement in terms of IADL results may be reasonable, because Bourne’s study sample consisted of community people, but our study samples consisted of patients referred to the clinics. The findings of different studies are different in this regard (Karakurt et al. 2017). 
With respect to pressure ulcer risk and according to the findings, most participants were at no risk group of developing pressure ulcer, and none of them was at very high-risk group. In the studies of Akca et al. (2015) and Cremasco et al. (2013), most individuals were at very high risk group of developing pressure ulcer, which are contrary to our results. The difference may be because of difference in subjects. The subjects in Akca et al. Study were hospitalized patients who stayed a long time in a rehabilitation care center, and in Cremasco et al. Study, the samples were hospitalized in intensive care units.
The current study results indicate that dependence in BADL and IADL has a strong and direct relationship with the risk of developing pressure ulcer (P<0.01). Similarly, the results of Aydın and Mucuk in a rehabilitation center in Turkey also showed that individuals who were more dependent in BADLs and IADLs were at increased risk for the development of pressure ulcers (P<0.01) (Aydin & Mucuk 2015). The results of Inan and Öztunç study entitled “Incidence of pressure ulcer in Turkey: A case study in an educational university” and findings of Kwong et al. Study entitled “Development of pressure ulcers in the elderly in nursing and home care centers: the impact of factors” similar to our study indicate that there is a significant relationship between pressure ulcer and independence level (Inan & Öztunç 2012; Kwong et al. 2009)

 


 


 


 

Bergquist-Beringer and Gajewski study findings showed a direct correlation between the level of dependence in BADL and IADL and pressure ulcer risk (Bergquist-Beringer & Gajewski, 2011). The results of this study is similar to the results of Dijkstra et al. Study entitled “Using the care dependency scale for identifying patients at risk for pressure ulcer”. They found out that dependency level can distinguish between patients at risk for pressure ulcer development and those who are not at risk (Dijkstra, Kazimier & Halfens 2015).
In this study, there were significant correlations between the risk of pressure ulcer development and variables of age, underlying diseases, disability, and specific drug use (P<0.001). The results of review and meta-analysis study of Karimian et al. Entitled “The incidence of pressure ulcer in Iran: A systematic review study and meta-analysis” in 2014 indicate that the prevalence of pressure ulcer increases with the increase of age (Karimian et al. 2016).
Raju et al. (2015) In their study entitled “Investigating factors associated with pressure ulcer development: An analytical method” found out that age had a statistically significant and positive correlation with pressure ulcer development (P<0.001). In the review study of Sedghi Goyaghaj et al. (2016) entitled “the underlying factors of pressure ulcer and its treatment and prevention”, the patient’s age along with several other factors was identified as the most important predictors of pressure ulcers.
 These study findings are in agreement with our study that could be due to lower movement in the elderly people. Akbari Sari et al. (2011) Concluded that age and some of underlying diseases like diabetes and high blood pressure had a correlation with the pressure ulcer risk, which is consistent with our results. Keller et al. (2002)Also proved the effect of impaired blood circulation and diabetes on pressure ulcer development. Underlying diseases with their associated problems such as inactivity or decreased tissue hypoperfusion can increase the risk of pressure ulcer. Disability can also increase the risk of pressure ulcer development by restricting mobility and taking medications such as non-steroidal anti-inflammatory drugs and beta-blockers altering the metabolism of the body. 

 


 


 


 
In this study, a negative correlation was found between the level of education and the risk of developing pressure ulcer (P<0.001). It seems that increasing knowledge and awareness of people can have a positive effect on their performance in preventing diseases and complications such as pressure ulcers. 
In this study, gender and BMI factors had no statistically significant relationship with the pressure ulcer development risk (P>0.05). This is consistent with the findings of Raju et al. (2015) (P<0.05) and Keller et al. (2002) who also found no relationship between gender and pressure ulcer risk. Based on the results of some studies, individuals with BMI of less than 18.5 are at higher risk of developing pressure ulcers (P<0.001) (Akca, Aydin & Gümüs 2015). This finding disagrees with our finding. The different results might be due to different study samples. Aydın and Mucuk (2015) found that people with a lower BMI had a higher risk of developing pressure ulcer. This study was conducted in a rehabilitation center that its different results with ours were due to different samples. 
The findings of this research can be useful in education, service delivery, and management areas. In the field of education, it is necessary to hold training classes and methods for nursing staff in order to teach them patients’ empowerment techniques. Also training programs for patients, public community, especially older people should be held with respect to strategies for increasing independence, performing ADLs, and decreasing dependence to care givers. In the area of service delivery, nursing staff can play different roles in the daily living of people; for example, they can provide individuals with step-by-step instructions for performing activities. In addition, nurses can substitute activities that do not encourage independency and physical activity with proper activities, or in order to reduce dependency, recommend using mechanical appliances such as crutches, canes, or walkers for the elderly. 
In the field of management, the most important aspect of optimizing management plans is the active and desirable presence of patients in care management. Nursing managers, by using individual-based care models, can increase the participation of patients in daily living activities and reduce their dependence in these activities. In this regard, they improve the self-care of individuals and help them prevent complications such as PUs by creating a stimulating environment. It should be noted that due to the descriptive and cross-sectional nature of the study and the self-reporting assessment tools, the results of the study should be used with caution.
