Samuriwo, Ray (PhD. Student) October 2010,


Effects of education and experience on nurses’ value of ulcer prevention,


British Journal of Nursing (Tissue Viability Supplement) volume 19 Number 20 (2010)

What value do nurses place on pressure ulcer prevention? /To determine the value that nurses place on pressure ulcer prevention.






Welsh Straussian grounded theory study Female Nurses ranging from second year nursing student to senior nurse managers recruited from a non-acute medical ward of 14 hospitals in one NHS trust and a university


-Convenience sampling. No specific information given.

-Indirect measures with, semi-structured focus group interviews.

-Instrument reliable because values are ambiguous and mean different things to different people.

-Nurses talked about their experiences about looking after patients with pressure ulcers, and the researcher elicited their values from what they said.

-Data was collected in a two stage process and interpreted through the Straussian grounded theory.

-Results were positive, as all the participants revealed how the value they placed on pressure ulcer prevention had gone from low to high.

-All identified the same key landmarks even though they had different levels of education and experience, become more proactive in preventing pressure ulcers

-The key point in the transition being an encounter with a patient with a high-grade pressure ulcer caused the nurses to reappraise their values.

-Education that nurses receive on pressure ulcer, prevention only appears to alter their value when they have some experience of looking after patients with pressure ulcer.


-Sample size small, non- randomized  not statistically significant, high concern for bias, minimum requirement is 20-30 individuals

-Lack of hands on of the participants, most interventions delegated to health care assistants and students.

-Values are primarily established by personal experience, an old weaker derived source of evidence. -Researcher is a student not an expert on the subject.

-Gender exclusive participants all women in.

-No statistical information given provided for comparison of high or low values.

Development of the inter RAI (Resident Assisted Instrument) Pressure Ulcer Risk Scale (PURS) for use in long-term care and home setting,


BioMed Central (BMC) doi:10.1186/1471-2318-10-67








The purpose of this study was to examine the potential of Minimum Data Set (MDS) assessment, mandated for use in Ontario LTC homes, to inform the risk of Pressure Ulcers (PU).





Quasi-experimental non-equivalent group design study.





Comparative correlations design, using independent and dependent variables





-Included an admission or baseline MDS assessment of residents having a stay of 14 days or longer (median time 91 days)

-Three LTC homes with n=257 with MDS and Braden Scale assessments; n=12,896 from eight LTC homes with baseline/ reassessment of MDS data, n=13,062 from Complex Continuing Care Hospital (CCC) and n=73,183 from long stay home care clients. All assessed during the same time, restricted to those with no recorded pressure ulcer.

-All assessments were done by trained clinical staff.







-Assessment using the RAI, data collection and analysis

-spearman Rank Correlation (all significant at p<0.0001

Logistic regression of new Pressure ulcers was used to determine those MDS items was statistically significant (at p=0.05 or below) in a multivariable, parsimonious model.

MDS items higher numbers more impairment


Instrument was valid but unreliable according to previously collected data





-LTC homes the Braden scale was tested for its predictive ability with PU down to 1%from 9% with a c-statistic of

0.676. In CCC patients, distribution skewed towards the high-risk end of 9.7% with a c-statistic 0.607. In long stay home care, inter RAI PURS leaned more towards low risk much lower that, in LTC and CCC at 2.6% with c-statistic of 0.629 data analyzed using the   SAS and SAS enterprise Miner Tree Desktop version 9.1.3 were used for all data analyses

-consistent with other literatures such as quality improvement in nursing homes (Abel RL 2005) and A longitudinal study of risk factors associated with the formation of PU (Brandeis GH et al 1994





-Risk assessment tools, including the Braden Scale, have been criticized for their generally

weak properties

D. Anthony et al (JCN 2008)

-No information available for palliative and hospital

Study not randomized controlled

-Demographic information was unavailable for Braden scale sample.

-Sample presented predominantly elder female residents.

Possibility of under reporting pressure ulcers such as stage I

Grading Category: Assignments


You will be starting your own literature review matrix (Word) this week. Based on your investigation of the literature from the library and online resources, you will identify two articles that you will use to support your research question and work towards development of your Evidence-Based Practice Project Proposal due in Week 15.

Assignment Instructions

  • Using your two selected journal articles, you will complete the first two rows in the literature matrix using the template provided.
  • Read your two journal articles and extract the necessary information needed to complete each row for each article.
  • Thus, at the end of this week, you will have two out of the eight rows of the literature review matrix completed. You will return to the literature review matrix in future weeks.

Please refer to the Grading Rubric for details on how this activity will be graded.
