Abstract
Background Integration of behavioural health into primary care clinics is an established model of care and important approach to eliminating mental health disparities, but demands on provider time is a barrier to mental health screening. The purpose of this study was to determine the feasibility of using a kiosk placed in a primary care clinic to screen for multiple mental health disorders.
Methods Quality improvement initiative with Plan-Do-Study-Act implementation and time series monitoring of utilisation outcomes.
Results A total of 281 screens were completed identifying positive screens for depression (30%) and bipolar disorder (17%). Post-traumatic stress disorder and concerning substance use were less common.
Conclusions Development of health information technology to facilitate behavioural health assessment in primary care is a promising approach to integrated care and provides additional benefits of population health monitoring.

Background
It has been 15 years since the 16th Surgeon General’s landmark report on mental health, which conveyed a central message that mental health is fundamental to health and that mental disorders are real health conditions. Yet, patients and providers continue to struggle with stigma and systems of care that make addressing mental health a challenge and eliminating disparities an elusive aim. Routine screening for depression in primary care is recommended when staff-assisted supports are in place.1 Health care professionals are also advised to ask adults about their drinking habits and provide counselling to those who drink at a risky or hazardous level.2 Comorbid mental health conditions are also prevalent in primary care and concerning in settings with high rates of unmet mental health needs.
Assessment of mental health is challenging in part because providers have a limited amount of time with each patient to collect important clinical data and provide preventive medical services.3,4 Social history and behavioural health information are among commonly missed preventive screens.5 This may in part be due to the perceived extended time to assess these domains, and the fact that it may represent more sensitive data. Relying on existing staff to interview patients is time consuming, and research has shown that patients are more likely to disclose sensitive information to a computer.6 Freely available standardised, validated self-assessments exist that can accurately detect depression (Patient Health Questionnaire, PHQ-2 & PHQ-9), substance abuse (Drug Abuse Screening Test, DAST-10, Alcohol Use Disorders Identification Test, AUDIT- 10), risk for bipolar disorder (Mood Disorders Questionnaire, MDQ) and post-traumatic stress disorder (Posttraumatic Stress Disorder-Primary Care, PTSD-PC). Having self-service kiosks that patients can engage for ‘wellness assessment’ and screening for risky use of substances and highly prevalent mood disorders in primary care is both patient-centred and promotes efficiency in patient flow as patients spend valuable time waiting during the clinic visit. Patients’ wait time can be used to collect important clinical information that providers could use to aid their decision-making and prioritisation of issues.
Grady Health System is one of the nation’s largest public hospitals. The Asa G. Yancey, Sr. M.D. Health Center (Asa Yancey), was the first of six neighbourhood health centres with comprehensive primary care services in the greater Atlanta community.
Asa Yancey provides primary and preventive health care to adult and paediatric patients. Additional services on site include nutrition, pharmacy, radiology and laboratory, social services, and family planning. Physicians employed with Grady Health System provide medical care with nurse practitioners and midwives on site. The clinic is located approximately five miles from the main campus, and in 2012, it had over 20,000 patient encounters, of which almost 15,000 were for adult patients. Consistent with the mission of the health system, the clinic provides primary care services to individuals regardless of their ability to pay. Of the patient population, within the clinic, 45% is uninsured; Medicare covers 20%, and 15% of the population is covered by Medicaid. The clinic population is predominantly English speaking (99%), non-Hispanic (91%) and African-American (96%). Of the patients, 68% are women, and the mean age is 52 years. Most of the patients are unmarried (56%) or divorced (17%). The clinic is staffed by six adult providers who provide 4.6 full-time equivalent (FTE) staffing for adult primary care services. Providers were previously trained in the use of paper versions of these standardised, validated instruments and were also trained in the use of treatment algorithms to respond to assessment results. Providers also participated in SBIRT (screening, brief intervention, referral and treatment) training, which included exposure to motivational interviewing techniques.
A quality improvement project was designed to pilot the feasibility and acceptability of a self-service kiosk in a primary care waiting room, and later, in triage areas. Prior to this improvement project, only some behavioural health domains were assessed routinely. When these data were collected, paper forms were completed and then scanned into electronic health record (EHR), or written within the progress note. This prohibited tracking of progress or outcomes at the individual patient or system level. Although there were some clinician-administered surveys that could have been written into the health system’s EHR with significant cost investment, this would also require more provider/staff time, and the benefits were perceived as limited due to the length of assessment time within the context of patient visits. The current report describes the kiosk pilot implementation and presents results from screening efforts.
Methods
The Institutional Review Board of Morehouse School of Medicine and the Office of Research Administration of Grady Health System approved this quality improvement project. The kiosk project involved development of an ‘EHR Ready’ application with customised software developed by project staff that would allow patients to complete behavioural health ‘wellness assessments’ while waiting for their appointments. The purpose of this software design was to facilitate interface and EHR integration if the health system decided to invest in patient portal software. The software was designed by a psychiatrist (GW) who developed the algorithm from standardised assessments previously validated for use in primary care7–14 in collaboration with Slabb, Inc., a kiosk vendor. A user flow with decision rules was created to enable algorithm administration on a kiosk platform (Figure 1).
No protected health information was collected for the pilot, and patients were prompted by the kiosk to print out their results to give to their provider in order to be used for patient care on the day of self-assessment (Images 1-7). Anonymous data were stored on the kiosk and periodically downloaded for use in performance improvement. The primary care kiosk pilot employed a comprehensive behavioural health screen where patients completed an algorithm-driven screening and assessment for depression, substance abuse, bipolar disorder, and PTSD; and if being treated within primary care for depression, they could complete symptom severity assessments at each follow-up visit. While the kiosk did not prevent users from repeating the assessment at multiple time points, patients were instructed at check in to complete the survey only if they had not done so before. In addition, prior to full implementation, staff and patients were invited to use the kiosk and provide feedback on ease of use and to observe self-administration. Those data were excluded from the analysis.
Results
During the pilot period, 281 wellness assessments were completed (Table 1). Depression was the most common condition identified (30%), with bipolar and hazardous drinking at high rates as well. As this was the first exposure to computerised screening for both clinic patients and providers, we expected a lag in technology adoption, which is reflected in the low overall number of screens (N = 281).
Plan-Do-Study-Act (PDSA) improvement methods were used to review monthly utilisation data and problem-solve strategies to engage patients. Screening and positive depression results from the pilot period along with major PDSA interventions are depicted in Figure 1. Representatives from front desk, nursing and provider staff were engaged as champions of the effort, and several challenges from patients (unplugging the kiosk to charge their phone, thinking it was an ATM) were overcome. As shown in Figure 2, upward trends in kiosk use occurred following efforts to engage nursing leadership, but based on feedback from clinic meetings, physician champions primarily drove use by encouraging their patients to complete the screen prior to their next visit, or the same day if a concern was identified. In addition to initial depression assessments, 94 follow-up depression screens were conducted and 25% were positive for depression. The followup assessment kiosk option was used for active management, and unique users could not be identified, limiting data interpretation.
Discussion
This was a pilot project that emerged from provider input into practice improvement preferences in the process of implementing integrated care. Current implementation models rely on staff-administered screening, usually limited to one or two behavioural health domains. This pilot study suggests that a patient-engaged screening method can detect more comprehensive behavioural health needs. Our PDSA findings stress the importance of implementation planning and additional strategies to encourage new technology adoption. In this case, more robust efforts to educate patients (signage and informational flyers) could have improved utilisation. Use of the kiosk did enable cliniclevel assessment of behavioural health needs with relatively minimal cost of new technology investment. This is a model that other clinics within the health system can adopt to encourage patients’ active engagement in addressing behavioural health needs within primary care settings and convey a message that their providers value attention to behavioural health concerns.
Conclusions
These results are preliminary and generalisability to other populations with differing comfort levels with technology is limited. Future research will require improved patient and provider education about the purpose of the kiosks. Adaptation to more discreet devices (i.e. tablets) could increase patient use. Replication in other clinics is possible at the cost of hardware and a software user license. Additional improvements are planned based on pilot results, including addition of an anxiety assessment and translation to Spanish.
