RESUMO
The authors identified individual randomized controlled trials from previous meta-analyses and additional searches, and then performed meta-analyses on cardiovascular disease outcomes and all-cause mortality. The authors assessed publications from 2012, both before and including the U.S. Preventive Service Task Force review. Their systematic reviews and meta-analyses showed generally moderate- or low-quality evidence for preventive benefits (folic acid for total cardiovascular disease, folic acid and B-vitamins for stroke), no effect (multivitamins, vitamins C, D, ß-carotene, calcium, and selenium), or increased risk (antioxidant mixtures and niacin [with a statin] for all-cause mortality). Conclusive evidence for the benefit of any supplement across all dietary backgrounds (including deficiency and sufficiency) was not demonstrated; therefore, any benefits seen must be balanced against possible risks.

OBJECTIVES: Unsafe household conditions could adversely affect safety and quality in home health care. However, risk identification tools and procedures that can be readily implemented in this setting are lacking. To address this need, we developed and tested a new household safety checklist and accompanying training program. METHODS: A 50-item, photo-illustrated, multi-hazard checklist was designed as a tool to enable home healthcare paraprofessionals (HHCPs) to conduct visual safety inspections in patients' homes. The checklist focused on hazards presenting the greatest threat to the safety of seniors. A convenience sample of 57 HHCPs was recruited to participate in a 1-hour training program, followed by pilot testing of the checklist in their patients' households. Checklist data from 116 patient homes were summarized using descriptive statistics. Qualitative feedback on the inspection process was provided by HHCPs participating in a focus group. RESULTS: Pretesting and posttesting determined that the training program was effective; participating HHCPs' ability to identify household hazards significantly improved after training (P<0.001). Using the checklist, HHCPs were able to identify unsafe conditions, including fire safety deficiencies, fall hazards, unsanitary conditions, and problems with medication management. Home healthcare paraprofessionals reported that the checklist was easy to use and that inspections were well accepted by patients. Inspections took roughly 20 minutes to conduct. CONCLUSIONS: Home healthcare paraprofessionals can be effectively trained to identify commonplace household hazards. Using this checklist as a guide, visual household inspections were easily performed by trained HHCPS. Additional studies are needed to evaluate the reliability of the checklist and to determine if hazard identification leads to interventions that improve performance outcomes.
