Effects of a computerized decision support system on pressure ulcers and malnutrition in nursing homes for the elderly.

BACKGROUND: Computerized decision support systems (CDSSs) have been shown to help health care professionals to avoid errors and improve clinical practice and efficiency in health care. Little is known about its influence on nursing practice and outcomes for residents in nursing homes.

AIM: The aim of this study was to evaluate the effects on the risk for and prevalence of pressure ulcers (PUs) and malnutrition of implementing a CDSS to improve prevention and care of PUs and also to improve nutrition in the elderly in nursing homes.

DESIGN SETTING AND PARTICIPANTS: The study used a quasi-experimental design with two intervention groups and one control group. A convenience sample of residents from 46 units in 15 nursing homes in rural areas in Norway was included. A total of 491 residents participated at baseline in 2007 and 480 residents at follow-up in 2009.

METHODS: The intervention included educational sessions in prevention of PUs and malnutrition for registered nurses (RNs) and nursing aides (NAs) in the two intervention groups. In addition, one intervention group (intervention group 1) had a CDSS integrated into the electronic healthcare record (EHR) based on two research-based risk assessment instruments: the Risk Assessment Pressure Scale (RAPS) for PU risk screening and the Mini Nutritional Assessment (MNA(®)) scale for screening nutritional status. In each participating nursing home trained RNs and NAs examined all residents who consented to participate on the RAPS and the MNA(®) scale. This examination included a skin assessment and details about PUs were collected.

RESULTS: The proportion of malnourished residents decreased significantly in intervention group 1 between the two data collection periods (2007 and 2009). No other significant effects of the CDSS on resident outcomes based on the RAPS and MNA(®) scores were found.

CONCLUSION: CDSSs used by RNs and NAs in nursing homes are still largely unexplored. A CDSS can be incorporated into the EHR to increase the meaningful use of these computerized systems in nursing home care. The effects of CDSS on healthcare provider workflow, clinical decision making and communication about preventive measures in nursing home practice still need further exploration. Based on results from our study, recommendations would be to increase both sample size and the number of RNs and NAs who participate in CDSS education programs.
