Discussion
No previous literature exists that reviews adherence to recommended metabolic monitoring guidance up to 1 year after antipsychotic initiation in a previously antipsychotic-naïve cohort within the VHA. Metabolic monitoring was overall incomplete with 0.2% of the cohort completing all recommended monitoring time points. Weight was the parameter that was least completed. Based on these findings, the authors concluded that efforts are needed to improve completion rates of atypical antipsychotic metabolic monitoring. In the final cohort, 6% of patients were noted to have progressed to T2DM in the first year after atypical antipsychotic initiation. The actual number of patients progressing to T2DM may be larger because not all received adequate blood glucose monitoring. For comparison, the Centers for Disease Control and Prevention released information in 2015 that stated that the US population has an annual T2DM incidence of about 1% for adults aged 45 to 64 years.7
We understand that individuals with mental health disorders are at increased risk of T2DM compared with that of the general population and hope that this comparison only serves to drive home the point that appropriate metabolic monitoring is vital for this subgroup. The strengths of this project include identification of an area for improvement and encouraging evidence-based monitoring. Utilization of clinical data is a cost-effective and efficient method to improve patient care.
Limitations
Limitations of this study include the data’s dependence on accuracy of entry by the end-user and a lack of available data regarding prescriptions dispensed outside of the VHA. Vital signs data may have been entered into patient notes and not documented in the vitals section of the current medical record causing the appearance of missing data. Access to VHA health services and patient adherence to follow-up appointments were not assessed in this project and could affect patient ability to complete follow-up. The final analysis included only patients who remained on 1 atypical antipsychotic for a year and were considered adherent with an MPR > 80% and did not consider less adherent patients. It is also possible that health care providers who closely monitor metabolic parameters after atypical antipsychotic initiation more frequently switch patients to an alternative atypical antipsychotic while others who monitor less also switch medications less frequently. This could lead to selection of patients with health care providers who are less adherent to metabolic monitoring recommendations.
Conclusions
As a result of this study, in VISN 21 several strategies will be implemented to improve monitoring. First, the results of this project will be shared with the subject matter experts of the VISN 21 Mental Health Task Force. This task force serves as a venue for clinicians to meet virtually, discuss clinical topics, as well as to create and distribute strategies to improve patient care. Clinicians at this forum will be encouraged to implement monitoring protocols into routine practice, share best practices with colleagues, and increase patient awareness about the importance of metabolic monitoring. Second, modifications may be applied to the electronic health record to guide metabolic monitoring order entry at the time of prescription entry, which includes development of clinical reminders and laboratory order sets. Third, the clinical data manager team may be leveraged to create an electronic report identifying patients currently receiving suboptimal monitoring in the first year after antipsychotic initiation. The patients identified in this report will be discussed at the recurring VISN 21 Mental Health Task Force meeting, and strong practices will be shared with the medical centers across VISN 21. Other strategies under consideration include requiring proof of metabolic monitoring completion prior to allowing further atypical antipsychotic refills and providing direct provider education regarding the ADA/APA metabolic monitoring recommendations via the academic detailing service in effort to standardize clinical care.
