DECREASING HOSPITALIZATION RATES FOR OLDER HOME CARE PATIENTS WITH SYMPTOMS OF DEPRESSION

OBJECTIVE: To target medically ill older home care patients with sympt oms of depression in order to reduce their rate of hospitalization. DE SIGN: A case-control study. SETTING: A private, nonprofit home care or ganization, the Visiting Nurse Association of St. Louis. PARTICIPANTS: Home care patients 65 years of age and older with symptoms of depress ion who were participants of a Total Quality Management (TQM) interven tion (n = 81) were compared with an historical control of home care pa tients 65 years of age and older with symptoms of depression (n = 69). INTERVENTION: Utilization of TQM principles to develop a plan includi ng: (a) an educational seminar on depression for home care staff invol ved in the project; (b) letters to physicians introducing the TQM proj ect; (c) use of the Geriatric Depression Scale (GDS) for screening; (d ) recommendation to the primary physician of a home social service (SS ) consultation for patients with a GDS of 10 to 14; (e) recommendation to the primary physician of three interventions for patients with a G DS greater than or equal to 15: home SS consultation + mental health ( MH), or gerontological nurse (GN) consultation + antidepressant medica tion (a pharmacotherapeutic algorithm sent by facsimile to the primary physician upon request). OUTCOME MEASURES: Hospitalization rates of t he control group compared with the TQM intervention group, the degree to which part (e) of the plan was implemented, and the effect this had on hospitalization rates. RESULTS: The TQM intervention patients had a higher mean age than the historical control patients but were not di fferent in percent female, percent white race, percent with a caregive r in the home, functional status, and in 15 of 16 diagnostic categorie s. Overall, the TQM intervention group had a hospitalization rate of 2 3.5% (19/81) compared with a rate of 40.6% (28/69) for the historical control group (P = .024). For part (e) of the plan (56/81 patients had a GDS greater than or equal to 15), 29/56 (52%) received the recommen ded SS consultation, 50/56 (89%) received the recommended MH or GN con sultation, and 32/56 (57%) received antidepressant medication. One typ e of intervention did not seem to lower hospitalization rates more tha n another although having received the MH or GN visits approached sign ificance (12/50, 24%; P = .052) when compared with the control group. CONCLUSION: Utilization of TQM principles and the development of an in tervention such as the one described here can decrease hospitalization rates for medically ill older home care patients with symptoms of dep ression.
