2008 Virginia Elder Oral Health Survey Logistics & Lessons Learned Elizabeth Barrett, DMD, MSPH Virginia Department of Health August 18, 2009
Logistics Why do a Statewide Survey? Purpose of Survey Populations Surveyed Survey Design & Administration Analysis (pending)
Why Do a Statewide Survey? • Minimal national and Virginia-specific oral health data regarding older adults • Limitations to Virginia BRFSS • Limited number and type of dental indicators • Limited ability to reach all elder populations • Inadequate data regarding homebound or high-risk elders of low SES • Virginia has not addressed oral health issues among the elderly or the need to increase access to dental services through improved dental coverage
Purpose of Survey • To collect specific oral health indices and information about self-care, medical conditions, access and utilization of oral health services • To document the oral health status of several elder sub-populations across the state, including Nursing Home (NH) residents and homebound seniors • To utilize results for policy and program planning purposes to address disparities in access to dental care and oral health outcomes among the elderly
Study Population • Virginia elders (65+ years) • Nursing home residents • Homebound • Attendees of senior meal congregates • Sample estimates calculated for each category based on statewide population estimates to obtain significant results at the state level • 3-5% error and a 95% confidence level were used • For NHs, used total bed capacity as a proxy to estimate this population in Virginia • Did not anticipate any problems obtaining a significant sample size within each category
Sampling: Nursing Home Residents • 274 facilities • Stratified population by health planning region to ensure geographic representation • Sample size calculated to reflect proportion of NH beds by region • Within each region, NHs stratified according to facility payment type and randomly selected from each category • NHs selected using this sampling scheme until an adequate sample size was obtained for each region
Sampling: Well Elders at Congregate Centers • Used a sampling scheme to select senior groups across the state • Stratified population by the 5 health planning regions • Sample size calculated from the statewide estimate of attendees to reflect the proportion of enrolled seniors by region • Senior congregates then randomly selected within each region until an adequate sample size had been obtained for each area
Sampling: Homebound Elders • Identified from a private corporation that provides home care for adults • 9 locations across the Commonwealth providing care to homebound individuals • Due to the smaller population, surveyed all seniors (no sampling)
Survey Design • Based on Kentucky Elder Oral Health Survey • Two components: Questionnaire and Clinical • Questionnaire variables • Demographics, risk factors, oral hygiene habits, access to dental services, oral health conditions • Clinical variables • Modified Basic Screening Survey (BSS) • Caries, soft tissue and gum disease, tooth loss, denture use • Oral Hygiene Index (OHI)
Questionnaire Variables • Demographics: age, sex, race, education, income • Health conditions: paralysis/stroke, diabetes, heart problems, dementia • Demonstration of dexterity/mobility • Tobacco and alcohol use
Questionnaire (continued) • Daily care: brushing, flossing, dentures • Satisfaction with oral health: ability to chew, speak, appearance • Presence of pain • Dental services: visited a dentist in past year (if no, why not; if yes, why)
Survey Administration • Survey conducted primarily by 3 hygienists • 2 public health dentists – congregate meal sites in their localities • A nurse, trained to recognize oral health indicators, surveyed the homebound population • Trained and calibrated • One full day of training provided followed by calibration in facilities on survey participants • Anticipated 6 months for data collection
Survey Administration • Contacted facility administrators and group directors for approval • Written individual informed consent required • Each participant assigned an ID number • No names recorded except on consent form
Survey Administration • Supplies needed for clinical survey • Headlamp, mirror, tongue depressor, gauze and floss • All examiners wore masks and gloves and were instructed to hand sanitize before and after each exam • Residents were given OH supplies tailored to their specific needs upon completion of the survey
Analysis (pending) • Clean and weight data across each subgroup • Analyze data separately for each elder subgroup • Descriptive statistics • Bi-variable analyses to determine associations between demographic predictors/risk factors and specific oral health outcomes • Multi-variable analyses to assess the predictive capability of known demographics and risk factors with regard to oral health outcomes
Lessons Learned What Worked? What Didn’t Work?
Lessons Learned What Worked? • Exceeded our expectation in numbers • Surveyed 1448 seniors • Clinical exam was easy to use • Worked well for the surveyors • Obtained the most valuable information • Selection process was clear • Epidemiologist’s sample process and lists for contacting facilities were easy to follow and made planning more efficient
Lessons Learned What Worked? • Congregate Meal Sites wanted to participate • No problem with getting approval to participate • Sites not selected called us to see if they could participate • Able to provide educational program during visit • Homebound interested in improved oral care • Stated many times to surveyor that they were grateful to know the status of their oral health • Many were unable to get to the dentist for exams • Grateful for hygiene supplies we provided
Lessons Learned What Didn’t Work? • Difficulty gaining approval in NHs • Facilities not interested in survey • Concern that the “state” would be in the facility • Questionnaire for NH Residents • Residents unable or unwilling to answer the questions in the survey • Family members not available to answer questions • Facility staff too busy to answer questions • Limited access to charts to obtain information
Lessons Learned What Didn’t Work? • Collecting data from homebound individuals took a lot of resources • Examiner averaged about 5 exams per 8 hour day in areas that were geographically challenging • Some homebound individuals were reluctant to let examiners in and answer questions • The examiner found it hard to leave because they wanted to talk to someone (loneliness)
Lessons Learned What Didn’t Work? • Initial estimate of congregate site participation was inflated • Each individual counts as a participant even if they attend just 1 day per year • Had to go to more congregate meal sites than initially anticipated • Project took a lot of coordination • A lot of time on calls to facilities • Preparing and approving travel for multiple individuals • Filling requests for supplies to examiners • Tracking and monitoring surveys • Scheduling support staff to record for examiners
Lessons Learned What Didn’t Work? • No identifying information on forms • Made it impossible to go back and obtain missing information after the survey • Consistent monitoring of multiple examiners • Although examiners were calibrated and forms were reviewed for completeness, final cleaning of data indicated that some questions were consistently missed as time progressed • Need to maintain ongoing monitoring of examiners
Lessons Learned What Didn’t Work? • Contracting for examiners • Process was long and tedious • Using an agency is extremely costly • Hard to manage examiners that are not compliant to procedures and deadlines set by survey coordinator • If possible, use existing staff
Conclusions • Survey method is a viable way to reach our target senior populations • In future, continue to use clinical component with slight changes and simplify questionnaire particularly with respect to NH residents • Survey took a lot of coordination, money, and other resources but it was worth it • Survey will provide valuable data regarding oral health status of Virginia elders • We look forward to analyzing the data and using it to develop new programs for Virginia’s seniors
