The agency says it responds to 99 percent of the most serious complaints within 24 hours. About a third of lower-level complaints don't get a response within 14 days as required.
The agency says it will complete about 1,550 nursing home investigations during a two-week statewide blitz this month. The new investigators will be hired in March.
The agency regulates 1,196 Texas nursing homes and investigated 16,200 complaints and incidents in fiscal year 2009.
