Instruction of hospitalized patients by respiratory therapists on metered-dose inhaler use leads to decrease in patient errors Song WS; Mullon J; Regan NA; Roth BJRespir Care 2005[Aug]; 50 (8): 1040-5BACKGROUND: Hospitalized patients have been shown to make several errors in using metered-dose inhalers (MDIs), which can lead to poor medication delivery. METHODS: This study was designed to look at the potential benefit of a respiratory therapist (RT) giving instruction on the use of MDIs to hospitalized patients with obstructive lung disease. A baseline group of 58 patients was observed by a physician while performing 2 actuations of their MDI and the number of errors they committed, based on the National Institutes of Health's recommended 8 steps for proper MDI use, was recorded. After a program of MDI instruction (which included encouragement to use a spacer) by an RT was performed, a second group of hospitalized patients was again observed by a physician to determine if their error rate was reduced. RESULTS: The baseline error rate was 6.72 (out of 15 possible) errors per patient, and improved to 2.43 errors per patient after RT-provided instruction (p < 0.001). This improvement was still significant after controlling for an increased use of spacers in the post-instruction group of patients (27.6% and 91.7% spacer use before and after education). CONCLUSIONS: Instruction of hospitalized patients with obstructive lung disease by an RT improves their correct use of MDIs and increases their use of spacers while in the hospital.|*Allied Health Personnel[MESH]|*Inpatients[MESH]|*Metered Dose Inhalers[MESH]|*Respiratory Therapy[MESH]|Administration, Inhalation[MESH]|Adult[MESH]|Aged[MESH]|Aged, 80 and over[MESH]|Asthma/drug therapy[MESH]|Equipment Failure[MESH]|Female[MESH]|Humans[MESH]|Male[MESH]|Middle Aged[MESH]|Patient Education as Topic/*methods[MESH]|Pulmonary Disease, Chronic Obstructive/drug therapy[MESH]|Washington[MESH] |
