session overview 1
Session Overview (1)
  • Basics of Research and Evaluation Design
  • Defining Meaningful Objectives
  • Identifying data relevant to patient handling/movement program implementation
session overview 2
Session Overview (2)
  • Methods of collecting data
  • Getting to Outcomes: analyzing and presenting results from your data
  • Examples from the New York State Safe Patient Movement and Handling Demonstration Project
defining terms
Defining Terms
  • Research means a systematic investigation, including development, testing, and evaluation, designed to develop or contribute to generalizable knowledge. (45 CFR46.102(d)).
    • Definition of research used by US government (e.g., Institutional Review Boards, human subjects)
defining evaluation
Defining Evaluation
  • Program evaluation is defined as follows: A systematic assessment of the results or outcomes of program efforts to measure actual outcomes against the intended outcomes of the program; to discover achievement and results; to discover deviations from planned achievements; to judge the worth of the program; to identify unintended consequences; and to recommend expansion, contraction, elimination, or modification of the program. (DOJ)
  • Evaluation is a specialized form of research
rationale for evaluation
Rationale for Evaluation
  • Broad options
    • Summative: outcomes
    • Formative: processes, implementation issues
    • Long-term sustainability
  • Make specific to your project and needs
  • Be inclusive in planning the evaluation
    • Get feedback from array of participants/constituencies
defining meaningful objectives
Defining Meaningful Objectives
  • Scope of the project
    • How large (1 facility, 100 facilities, number of residents/clients)
    • Type of facility (acute, long-term, home care)
    • Type of clients/residents/patients
    • Number of staff
purpose of data collection
Purpose of Data Collection
  • Write down your program objectives
  • Share them with others (get feedback)
  • Link the objectives to specific data
    • Project milestones and specific dates
    • Worker injury data
    • Staff retention
    • Lost time
access to relevant data
Access to Relevant Data
  • Simple but not easy!!!
  • Can you truly get the information you need
  • Reasonableness as initial assessment of access (Does it exists, Can it be accessed, In what format)
quantitative qualitative data
Quantitative/Qualitative Data
  • Quantitative data: something that is measureable as a number
    • such as a count of events, rate of injury, costs, scale
    • Instrument-based questions
    • Usually analyzed using statistical techniques
    • Focus is on outcomes/summative evaluation
quantitative qualitative data11
Quantitative/Qualitative Data
  • Qualitative data: non-numerical measures
    • Verbal feedback, narratives, open-ended feedback
    • Analyzed from a context viewpoint
    • Usually informs process evaluation
  • Mixed methods evaluations utilize quantitative and qualitative data
data for safe patient handling projects
Data for Safe Patient Handling Projects
  • Workplace data
    • Occupational injuries (back, strains, shoulder, etc)
    • Time off/lost time
    • Worker retention/turnover
  • Patient Data
    • Injuries, satisfaction
  • Systems/environment data
    • Ergonomic/safety committees
    • Training/updates
data collection methods
Data Collection Methods
  • Record data
    • Injuries/OSHA/DOL logs, sheets etc.
    • HR data
    • Business office data
    • Patient injury data
  • May be more challenging than anticipated!!!!
  • Need specific protocol for each type of record data
  • Issues with validity/data quality
data collection methods14
Data Collection Methods
  • Surveys/Questionnaires
    • Self-report of injuries to compare with record data
    • Staff assessment of program
    • Implementation issues
    • Key knowledge assessment
    • Staff satisfaction/Patient satisfaction
    • Open-ended feedback
data collection methods15
Data Collection Methods
  • Key informants
    • Specific questions regarding the program
    • Interview with persons knowledgeable about program
    • Can be done with group of informants
  • Focus groups
    • Group process
    • Questions with a group of similar people
data quality issues
Data Quality Issues
  • Validity and reliability
    • Validity is whether something is an accurate measure
    • Reliability is whether the measure is stable (test-retest, internal consistency for scales)
  • Data quality is variable
    • Biases
    • Need for convergent information from multiple sources
getting to outcomes
Getting to Outcomes
  • Methods of analyzing your data
    • Simple non-statistical techniques
    • Comparisons, interpretations of qualitative data, assessment of milestones
  • Statistical methods
    • Allows one to assess the probability that changes are real versus being due to chance
    • Usually requires training in methods
getting to outcomes18
Getting to Outcomes
  • Statistical considerations
    • Need for adequate sample size and valid measures
  • Need to use statistical methods appropriate for the data sources
    • Pre-/post tests, trends overtime, comparison of local data with state and national data
    • Descriptive statistics (frequencies, means) often used for survey data
getting to outcomes19
Getting to Outcomes
  • Match your data analysis and presentation to the needs of your audience!!
    • Scientific publication
    • Internal reports
    • Funding agencies
  • Safe Patient Handling and Movement Project
  • NYS demonstration project
    • Three long-term care facilities
    • Two hospitals
  • Evaluate impact (summative eval)
  • Assess issues that impede/assist implementation (formative eval)
data sources
Data sources
  • Record data
    • Worker injuries
    • Days lost
    • Type of injury
    • Calculated costs
    • For period of three years prior to project and three years during project
    • Adding patient injury data
lessons and recommendations
Lessons and Recommendations
  • Getting data is harder than it sounds!
    • Key staff turnover
  • Data quality is a major issue for record data
    • Potential biases, changes in record methods over time
  • Even “required” data may not be readily available
lessons and recommendations34
Lessons and Recommendations
  • Need to build rapport/relationship
    • With your team
    • With key administrators
    • With union reps
    • With key nursing and training staff
  • Be persistent
  • Develop procedures for contacts and follow ups
lessons and recommendations35
Lessons and Recommendations
  • Baseline data provides useful insights
    • Tremendous variability in some measures (e.g., days lost)
    • Small populations and the impact of a single major injury can skew the data
    • Adds more degree of difficulty for single sites and demonstration projects
    • Formative: processes, implementation issues
lessons and recommendations36
Lessons and Recommendations
  • Surveys and staff feedback are critically important
    • Showed that staff doesn’t recognize importance of ergo teams
    • Differences in perceptions regarding program between floor staff and administrators
    • Injury reports from survey indicates that many injuries and near misses are not reported
