Clinical Trial Summary

Patients meeting eligibility criteria will be randomized into two groups, one receiving pharmacogenetic testing and the other not receiving pharmacogenetic testing. In this open-label trial, a pharmacist will make medication therapy recommendations using YouScript® Personalized Prescribing System for patients who receive genetic testing and standard drug information resources per usual for patients who do not undergo pharmacogenetic testing.


Description:

Both groups will be followed for 60 days. The number of re-hospitalizations and emergency department (ED) visits will be recorded as well as time to first re-hospitalization and time to first ED visit. Select Outcome and Assessment Information Set (OASIS) metrics (e.g. M1034, M1242, M1710, M1720, M1745, M2110) and Patient Health Questionnaire (PHQ)-2 will be evaluated and documented at time of admission to home health, at 30 days, and at 60 days for improvement in overall status, pain, confusion, anxiety, depression, disruptive behavior, and the need for assistance with activities of daily living (ADLs) and instrumental activities of daily living (IADLs). The number of falls will be collected as well as the proportion of YouScript® recommendations accepted by study pharmacist and passed on to clinicians and the proportion of recommendations accepted by clinicians.

Outcome

Type Measure Description Time frame Safety issue
Primary Number of Re-hospitalizations at 30 and 60 Days The primary outcomes included the number of re-hospitalizations at 30 and 60 days. 30 days, 60 days post discharge
Primary The Primary Outcomes Included the Number of Emergency Department Visits at 30 and 60 Days. Assessed the number of Emergency Department visits at 30 and 60 days post discharge with pharmacogenetic testing and YouScript® Personalized Prescribing system. 30 days, 60 days post discharge
Secondary Time to 1st Re-hospitalization To assess time to first re-hospitalization, we compared the exploratory time-to-event outcomes between the tested and untested groups at 30 days and 60 days. These outcomes were measured using cumulative percentage events at 30 and 60 days, referring to the percentage of subjects re-hospitalized before or at 30 and 60 days. 30 days, 60 days
Secondary Time to 1st Emergency Department Visit To assess time to first emergency department visit, we compared the exploratory time-to-event outcomes (time to 1st ED visit) between the tested and untested groups at 30 days and 60 days. These outcomes were measured using cumulative percentage events at 30 and 60 days, referring to the percentage of subjects who visited the emergency department before or at 30 and 60 days. 30 days, 60 days
Secondary Overall Status as Measured by Outcome and Assessment Information Set (OASIS) Scale We assessed the impact of genetic testing on overall status according to OASIS M1034 at 30 and 60 days post discharge. OASIS measures various data items to assess home health care quality and performance. OASIS M1034, one data point in the OASIS system, measures overall patient status on a scale of 0 to 3, with a lower score indicating better overall status. 30 days, 60 days post discharge
Secondary Pain as Measured by OASIS Scale We assessed the impact of genetic testing on patient pain frequency according to OASIS M1242 at 30 and 60 days post discharge. OASIS measures various data items to assess home health care quality and performance. OASIS M1242, one data point in the OASIS system, measures patient pain frequency on a scale of 0 to 4, with a lower score indicating less frequent pain. 30 days, 60 days post discharge
Secondary Confusion as Measured by OASIS Scale We assessed the impact of genetic testing on frequency of confusion according to OASIS M1710 at 30 and 60 days post discharge. OASIS measures various data items to assess home health care quality and performance. OASIS M1710, one data point in the OASIS system, measures patient confusion frequency on a scale of 0 to 4, with a lower score indicating less frequent confusion. 30 days, 60 days post discharge
Secondary Anxiety as Measured by OASIS Scale We assessed the impact of genetic testing on frequency of anxiety according to OASIS M1720 at 30 and 60 days post discharge. OASIS measures various data items to assess home health care quality and performance. OASIS M1720, one data point in the OASIS system, measures patient confusion frequency on a scale of 0 to 3, with a lower score indicating less frequent confusion. 30 days, 60 days post discharge
Secondary Depression as Measured by Patient Health Questionnaire (PHQ)-2 Scale We assessed the impact of genetic testing on frequency of depressive mood according to PHQ-2 at 30 and 60 days post discharge. PHQ-2 evaluates patient depression by assessing two factors: frequency of little interest or pleasure in doing things and frequency of feeling down, depressed, or hopeless. This outcome measure assessed the second factor, frequency of feeling down or depressed. The scale for this factor ranges from 0 to 3, with a lower score represented less frequent depressive feelings. 30 days, 60 days post discharge
Secondary Disruptive Behavior as Measured by OASIS Scale We assessed the impact of genetic testing on frequency of disruptive behavior according to OASIS M1745 at 30 and 60 days post discharge. OASIS measures various data items to assess home health care quality and performance. OASIS M1745, one data point in the OASIS system, measures frequency of disruptive behavior by patient on a scale of 0 to 5, with a lower score indicating less frequent disruptive behavior. 30 days, 60 days post discharge
Secondary Activities of Daily Living as Measured by OASIS Scale We assessed the impact of genetic testing on the frequency of activities of daily living (ADL) and instrumental activities of daily living (IADL) assistance according to OASIS M2110 at 30 and 60 days post discharge. OASIS measures various data items to assess home health care quality and performance. OASIS M2110, one data point in the OASIS system, measures frequency of receiving ADL/IADL assistance on a scale of 0 to 5, with a lower score indicating less frequent assistance. 30 days, 60 days post discharge
Secondary Number of Falls as Measured by Tabulation To assess whether YouScript® testing decreases falls 60 days
Secondary Number of Pharmacist-accepted of Recommendations as Measured by Tabulation To assess the proportion of YouScript® Personalized Prescribing System recommendations accepted by the study pharmacist and passed on to clinicians. 60 days
Secondary Number of Clinician-accepted of Recommendations as Measured by Tabulation To assess the proportion of study pharmacist recommendations acted on by clinicians. 60 days
