Patient Partnership Tools to Support Medication Safety in Community-Dwelling Older Adults: Protocol for a Nonrandomized Stepped Wedge Clinical Trial.

BACKGROUND: Preventable harms from medications are significant threats to patient safety in community settings, especially among ambulatory older adults on multiple prescription medications. Patients may partner with primary care professionals by taking on active roles in decisions, learning the basics of medication self-management, and working with community resources. OBJECTIVE: This study aims to assess the impact of a set of patient partnership tools that redesign primary care encounters to encourage and empower patients to make more effective use of those encounters to improve medication safety. METHODS: The study is a nonrandomized, cross-sectional stepped wedge cluster-controlled trial with 1 private family medicine clinic and 2 public safety-net primary care clinics each composing their own cluster. There are 2 intervention sequences with 1 cluster per sequence and 1 control sequence with 1 cluster. Cross-sectional surveys will be taken immediately at the conclusion of visits to the clinics during 6 time periods of 6 weeks each, with a transition period of no data collection during intervention implementation. The number of visits to be surveyed will vary by period and cluster. We plan to recruit patients and professionals for surveys during 405 visits. In the experimental periods, visits will be conducted with two partnership tools and associated clinic process changes: (1) a 1-page visit preparation guide given to relevant patients by clinic staff before seeing the provider, with the intention to improve communication and shared decision-making, and (2) a library of short educational videos that clinic staff encourage patients to watch on medication safety. In the control periods, visits will be conducted with usual care. The primary outcome will be patients' self-efficacy in medication use. The secondary outcomes are medication-related issues such as duplicate therapies identified by primary care providers and assessment of collaborative work during visits. RESULTS: The study was funded in September 2019. Data collection started in April 2023 and ended in December 2023. Data was collected for 405 primary care encounters during that period. As of February 15, 2024, initial descriptive statistics were calculated. Full data analysis is expected to be completed and published in the summer of 2024. CONCLUSIONS: This study will assess the impact of patient partnership tools and associated process changes in primary care on medication use self-efficacy and medication-related issues. The study is powered to identify types of patients who may benefit most from patient engagement tools in primary care visits.

Understanding the Information Needs of Pharmacy Staff Using CancelRx: A Qualitative Study of the Use of Prescription E-cancellation.

Background: Although electronic prescription cancellation such as via CancelRx can facilitate critical communication between prescribers and pharmacy staff about discontinued medications, there is little work that explores whether CancelRx meets the needs of pharmacy staff users. Objective: This study leverages qualitative interviews with pharmacy staff to address the following question: When medication changes are made by a prescriber using CancelRx, what information is needed by pharmacy staff to make correct and effective decisions in their roles in medication management? Methods: We conducted an inductive thematic analysis of interviews with 11 pharmacy staff members (pharmacists and pharmacy technicians) across three outpatient community pharmacy sites within an academic health care system. Results: Three information needs themes were consistently identified by both pharmacists and pharmacy technicians: prescriber intent when initiating the CancelRx, clinical rationale for the medication change, and intended medication regimen. Notably, both pharmacists and pharmacy technicians often reported seeking multiple information needs not fully addressed by CancelRx in the electronic health record (EHR) to achieve the shared goals of correct dispensing of medications and supporting patient self-management. Conclusions: Our qualitative analysis reveals that outpatient community pharmacy staff in an academic health care system often seek additional information from the (EHR) following medication changes communicated by CancelRx to meet their information needs. Ideally, the prescriber would provide sufficient information through CancelRx to automatically identify all discontinued prescriptions. These limitations highlight the need for design features that support routine communication of needed information at the time of a medication change, such as structured data elements.

Pharmacy e-Prescription Dispensing Before and After CancelRx Implementation.

Importance: An estimated 1.5% to nearly 5% of medications are dispensed after discontinuation in the electronic health record (EHR), with 34% meeting criteria for high risk of potential harm. Objective: To evaluate the association of the implementation of e-prescription cancellation messaging (CancelRx) with medication dispensing after discontinuation of e-prescriptions in the EHR. Design, Setting, and Participants: This case series with interrupted time series analysis included patients who had at least 1 medication e-prescribed in ambulatory care to a health system pharmacy and discontinued in the 2-year study period from 1 year prior to approximately 1 year after CancelRx implementation (January 15, 2018, to December 7, 2019). Prior to CancelRx implementation, changes to e-prescribed medications within the EHR were not electronically communicated to health system pharmacies, which used separate pharmacy management software. Statistical analysis was performed from November 2020 to June 2023 (primary analysis from March 2021 to May 2022). Exposure: Implementation of CancelRx. Main Outcomes and Measures: The primary outcome was the proportion of e-prescribed medications dispensed and sold to patients by pharmacies within 6 months after discontinuation in the EHR. A medication was defined as dispensed after discontinuation if the timestamp of dispensing was at least 1 minute and less than 6 months after the timestamp of discontinuation in the EHR. A secondary outcome was the proportion of discontinued medications that was reordered within 120 days. Results: A total of 53 298 qualifying e-prescriptions that were discontinued were identified for 17 451 unique patients (mean [SD] age, 50.6 [18.2] years; 9332 women [53.5%]). After CancelRx implementation, 22 443 (85.9%) of the 26 127 discontinued e-prescriptions resulted in a CancelRx transaction. In interrupted time series analysis, the proportion of prescriptions dispensed after discontinuation decreased from a baseline of 8.0% (2162 of 27 171) to 1.4% (369 of 26 127; P < .001), without a significant week-to-week trend (ß = 0.000158; P = .37). Conclusions and Relevance: In this case series with interrupted time series analysis, findings suggest that CancelRx implementation was associated with an immediate and persistent reduction in the proportion of e-prescriptions sold after discontinuation in the EHR. Widespread implementation of CancelRx may significantly improve medication safety through the reduction of medication dispensing after discontinuation by prescribers.

Discontinuation of outpatient medications: implications for electronic messaging to pharmacies using CancelRx.

Electronic communication of prescription discontinuation, or CancelRx, has the potential to improve medication safety. We aimed to describe the proportion of discontinued outpatient medications that would result in a CancelRx message to understand its impact on medication safety. We used a data report to identify all outpatient medications discontinued in the electronic health record (EHR) of an academic health system in 1 month (October 2018). Among all 63 485 medications discontinued, 23 118 (36.4%) were e-prescribed, 25 982 (40.9%) were patient-reported or reconciled, and the remainder prescribed nonelectronically. Discontinued high-risk medications were more likely to be e-prescribed (2768 of 5896, 47.0%). A discontinuation reason was specified in 37 353 (58.9%) of all discontinued medications. Approximately one-third to one-half of discontinued medications were e-prescribed within the same EHR and would result in a CancelRx message to the pharmacy. Extension of this functionality to medications reconciled in the EHR could significantly expand the impact of CancelRx on medication safety. In addition, complete and accurate discontinuation reasons are needed to optimize CancelRx implementation.

The Impact of Electronic Communication of Medication Discontinuation (CancelRx) on Medication Safety: A Pilot Study.

OBJECTIVES: This study aimed to evaluate the impact of electronic communication of medication discontinuation from prescribers to pharmacies (CancelRx) on medication safety. METHODS: We used electronic health record (EHR) data to identify medications that were e-prescribed from a pilot practice to a health system pharmacy and subsequently discontinued before or after CancelRx implementation (January 16-April 15, 2018 versus 2019). We matched these EHR data to pharmacy management software data to identify medications that were sold to patients in the 6 months after discontinuation. As a surrogate for unintended cancellation, we also identified medications refilled within 120 days of discontinuation. We conducted a medical record review to identify documentation of prescriber intent to discontinue these medications. RESULTS: CancelRx implementation prevented prescriptions from being sold after discontinuation in the EHR (42 of 392 [10.7%] versus 0 of 387 [0.0%], P < 0.0001), but only 15 of 42 (35.7%) had documented intent to discontinue the medication (15 of 392, or 3.8% overall). There was a nonsignificant increase in the proportion of discontinued medications reordered within 120 days (10.0% versus 12.7%, P = 0.23). Medical record review of reordered prescriptions after CancelRx implementation found that 10 of 49 (10 of 387, or 2.6% overall) might have been unintentionally canceled. CONCLUSIONS: Implementation of CancelRx eliminated the sale of e-prescribed medications after discontinuation in the EHR but might result in the unintentional cancellation of some prescriptions. Strategies to increase situational awareness of providers and pharmacy staff, including increased visibility of CancelRx, clear distinctions between active and expired prescriptions, and transmission of the reason for discontinuation, might reduce the risk of unintentional cancellations.

Utility of an Electronic Health Record Report to Identify Patients with Delays in Testing for Poorly Controlled Diabetes.

BACKGROUND: Reducing hemoglobin A1c (HbA1c) is essential for patients with poorly controlled diabetes. However, delays in HbA1c testing are common, and incomplete electronic health record (EHR) reports hinder identification of patients who are overdue. This study sought to quantify how often an EHR report correctly identifies patients with HbA1c testing delays and to describe potential contributing factors. METHODS: Using an EHR report, the researchers identified adult patients who had an HbA1c > 9.0% between October 2017 and March 2018 and a suspected delay (for example, another HbA1c had not resulted within six months). A retrospective chart review of 200 randomly selected records was performed to confirm delays in testing. Secondary measures were collected from 93 charts to evaluate associated factors. RESULTS: A total of 685 patients with suspected delays were identified. On chart review (N = 200), 82.0% were confirmed. Nine percent of patients had a timely repeat result, but the result was not in a discrete field within the EHR. Another 8.5% were never expected to return. Among a subset of confirmed delays, patients often received lifestyle counseling, but less than half had documented discussions about repeat glycemic testing. Also, 74.2% had a timely follow-up appointment scheduled but the majority (85.5%) were missed. CONCLUSION: Most suspected delays in HbA1c testing were confirmed; however, a substantial minority were misclassified due to missing data or follow-up care outside the health system. Current solutions to improve data quality for HbA1c are labor intensive and highlight the need for better integration of health care data. Missed appointments were commonly noted among patients with delays in care and are a potential target for improvement.

Impact of CancelRx on discontinuation of controlled substance prescriptions: an interrupted time series analysis.

BACKGROUND: Prescription opioid misuse is a serious national crisis; in 2018 the top drugs involved in prescription overdose deaths included pain medications (opioids), benzodiazepines, and stimulants. Health information technology (health IT) provides a means to address this crisis through technologies that streamline the prescribing and discontinuation process. CancelRx is a health IT function that communicates when medications, such as controlled substances, are discontinued at the clinic and therefore should not be filled at the pharmacy. Prior to CancelRx, the communication of discontinued medications was a manual process, requiring the patient or a clinic staff member to personally contact the pharmacy to inform them of the change. The objective of this study was to assess how controlled substance medication discontinuations were communicated over time, before and after the implementation of CancelRx. METHODS: Secondary data from a midwestern academic health system electronic health record and pharmacy platform were collected 12-months prior to CancelRx implementation and for 12-months post implementation. The study utilized an interrupted time series analysis (ITSA) to capture the percentage of controlled substance medications that were discontinued in the clinic's electronic health record and discontinued in the pharmacy's dispensing software. The ITSA plotted the percentage of successful discontinuation messages over time, particularly after the health system's implementation of CancelRx, a novel technology. RESULTS: After CancelRx implementation there was an immediate (change = 77.7 percentage point) and significant (p < 0.001) increase in the number of controlled substance medications that were successfully discontinued at the pharmacy after being discontinued in the clinic. This change was sustained in the year following CancelRx (slope = 0.03 pp, 95% CI - 0.050 to 0.110) and did not revert to pre-CancelRx levels. The health IT functionality was able to effectively complete discontinuation tasks and potentially reduce workload for clinic staff. CONCLUSIONS: Overall, this study demonstrates the role that technology can play in promoting communication between clinics and pharmacies, especially when medications such as controlled substances are discontinued.

High Concurrent Use of Sulfonylureas and Antimicrobials With Drug Interactions Causing Hypoglycemia.

OBJECTIVES: Sulfonylureas, the second most common oral diabetes treatment, have interactions with antimicrobials that substantially increase the risk of hypoglycemia. The objectives of this study are to quantify the concurrent use of sulfonylureas and interacting antimicrobial in U.S. ambulatory care and to examine whether interacting antimicrobials are used for an appropriate indication. METHODS: We analyzed the 2006-2016 National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey, annual probability samples of visits to U.S. office-based physicians. We determined nationally representative estimates of visits for adults with concurrent use of sulfonylureas and 7 antimicrobials with established interactions. We examined whether visit diagnoses included appropriate indications for antibiotics according to national guidelines. RESULTS: There were 2.5 million visits per year (95% confidence interval [CI] 2.2-2.9) in which sulfonylureas were used with systemic antimicrobials, of which 1 million (95% CI, 0.8-1.2) or 38.0% (95% CI, 32.3%-44.0%) were interacting antimicrobials. Sulfonylurea users had similar odds of interacting antimicrobial use as patients using diabetes medications without antimicrobial interactions (adjusted odds ratio, 1.07; 95% CI, 0.82-1.40). The most common interacting antimicrobials used with sulfonylureas were fluoroquinolones, accounting for 59.9% (95% CI, 50.7%-68.2%) of antimicrobials, and sulfamethoxazole-trimethoprim, accounting for 21.1% (95% CI, 14.8%-29.2%). There was no appropriate antibiotic indication in 69.7% (95% CI, 55.2%-81.1) of visits with interacting antibiotic use. CONCLUSIONS: Sulfonylureas and antimicrobials with potentially hazardous interactions are frequently used together. To reduce resultant hypoglycemic events, there is a need for interventions to increase physician awareness and promote antibiotic stewardship.

Are Mental Health and Substance Use Disorders Risk Factors for Missed Acute Myocardial Infarction Diagnoses Among Chest Pain or Dyspnea Encounters in the Emergency Department?

STUDY OBJECTIVE: To assess if having a mental health and/or substance use disorder is associated with a missed acute myocardial infarction diagnosis in the emergency department (ED). METHODS: This was a retrospective cohort analysis (2009 to 2017) of adult ED encounters at Kaiser Permanente Southern California. We used the validated symptom-disease pair analysis of diagnostic error methodological approach to "look back" and "look forward" and identify missed acute myocardial infarctions within 30 days of a treat-and-release ED visit. We use adjusted logistic regression to report the odds of missed acute myocardial infarction among patients with a history of mental health and/or substance use disorders. RESULTS: The look-back analysis identified 44,473 acute myocardial infarction hospital encounters; 574 (1.3%) diagnoses were missed. The odds of missed diagnoses were higher in patients with mental health disorders (odds ratio [OR] 1.48, 95% confidence interval [CI] 1.23 to 1.77) but not in those with substance abuse disorders (OR 1.22, 95% CI 0.91 to 1.62). The highest risk was observed in those with co-occurring disorders (OR 1.90, 95% CI 1.30 to 2.76). The look-forward analysis identified 325,088 chest pain/dyspnea ED encounters; 508 (0.2%) were missed acute myocardial infarctions. No significant associations of missed acute myocardial infarction were revealed in either group (mental health disorder: OR 0.92, 95% CI 0.71 to 1.18; substance use disorder: OR 1.22, 95% CI 0.80 to 1.85). CONCLUSION: The look-back analysis identified patients with mental illness at increased risk of missed acute myocardial infarction diagnosis, with the highest risk observed in those with a history of comorbid substance abuse. Having substance use disorders alone did not increase this risk in either cohort. The look-forward analysis revealed challenges in prospectively identifying high-risk patients to target for improvement.

Patient perceptions of safety in primary care: a qualitative study to inform care.

Patients' perspectives on patient safety have rarely been incorporated into quality initiatives in primary care. Our objective was to understand the patient perspective on patient safety in patient-centered medical homes (PCMHs). We conducted 12 patient focus groups/interviews in nine sites with 65 patients at a geographically diverse sample of National Committee on Quality Assurance Level 3 recognized PCMHs across three states. Using a patient safety framework, we coded and analyzed interviews for overarching themes and subthemes across patient safety domains. Overarching themes focused on (1) both clear and timely communication with and between clinicians and (2) trust in the care team, including being heard, respected, and treated as a whole person. Other themes important to specific patient safety domains included sharing of and access to information, patient education and patient-centered medication reconciliation process, clear documentation for the diagnostic process, patient-centered comprehensive visits, and timeliness of care. Communication and trust are key to patient perceptions of safe primary care. Focusing on these themes across safety domains may help to make primary care both more patient-centered and safer, and should be considered in future ambulatory safety initiatives.

Rate of sepsis hospitalizations after misdiagnosis in adult emergency department patients: a look-forward analysis with administrative claims data using Symptom-Disease Pair Analysis of Diagnostic Error (SPADE) methodology in an integrated health system.

OBJECTIVES: Delays in sepsis diagnosis can increase morbidity and mortality. Previously, we performed a Symptom-Disease Pair Analysis of Diagnostic Error (SPADE) "look-back" analysis to identify symptoms at risk for delayed sepsis diagnosis. We found treat-and-release emergency department (ED) encounters for fluid and electrolyte disorders (FED) and altered mental status (AMS) were associated with downstream sepsis hospitalizations. In this "look-forward" analysis, we measure the potential misdiagnosis-related harm rate for sepsis among patients with these symptoms. METHODS: Retrospective cohort study using electronic health record and claims data from Kaiser Permanente Mid-Atlantic States (2013-2018). Patients ≥18 years with ≥1 treat-and-release ED encounter for FED or AMS were included. Observed greater than expected sepsis hospitalizations within 30 days of ED treat-and-release encounters were considered potential misdiagnosis-related harms. Temporal analyses were employed to differentiate case and comparison (superficial injury/contusion ED encounters) cohorts. RESULTS: There were 4,549 treat-and-release ED encounters for FED or AMS, 26 associated with a sepsis hospitalization in the next 30 days. The observed (0.57%) minus expected (0.13%) harm rate was 0.44% (absolute) and 4.5-fold increased over expected (relative). There was a spike in sepsis hospitalizations in the week following FED/AMS ED visits. There were fewer sepsis hospitalizations and no spike in admissions in the week following superficial injury/contusion ED visits. Potentially misdiagnosed patients were older and more medically complex. CONCLUSIONS: Potential misdiagnosis-related harms from sepsis are infrequent but measurable using SPADE. This look-forward analysis validated our previous look-back study, demonstrating the SPADE approach can be used to study infectious disease syndromes.

Patient and family engagement strategies for children and adolescents with chronic diseases: A review of systematic reviews.

OBJECTIVE: Patient and family engagement is important for family-centered care, particularly for children and adolescents with chronic disease. We aimed to 1) identify available evidence from systematic reviews on engagement strategies used to help children, adolescents, and their caregivers manage chronic conditions, and 2) identify gaps in the literature. METHODS: We searched PubMed and CINAHL from January 2015 to January 2020 for systematic reviews on patient and family engagement strategies in the pediatrics population (<18 years). Strategies were categorized by direct patient care, health system, and community policy levels. We excluded reviews if interventions were unidirectional or without comparison. RESULTS: We identified 25 systematic reviews. Twenty-two evaluated direct patient care, with 14 (279 unique studies) exclusively in pediatrics and 8 (24 unique studies) that included pediatric results with adults. Three reviews (9 unique studies) evaluated health system strategies. Direct patient care reviews focused on self-management support (n = 16) and shared decisionmaking (n = 6). Asthma was the most frequently evaluated condition (n = 14). CONCLUSIONS AND PRACTICE IMPLICATIONS: Engagement strategies for children and adolescents with chronic disease are focused on direct patient care, particularly for asthma. More research is needed to address engagement for broader populations, expanded outcomes, and at health system and community levels.

Antecedent treat-and-release diagnoses prior to sepsis hospitalization among adult emergency department patients: a look-back analysis employing insurance claims data using Symptom-Disease Pair Analysis of Diagnostic Error (SPADE) methodology.

OBJECTIVES: The aim of this study was to identify delays in early pre-sepsis diagnosis in emergency departments (ED) using the Symptom-Disease Pair Analysis of Diagnostic Error (SPADE) approach. METHODS: SPADE methodology was employed using electronic health record and claims data from Kaiser Permanente Mid-Atlantic States (KPMAS). Study cohort included KPMAS members ≥18 years with ≥1 sepsis hospitalization 1/1/2013-12/31/2018. A look-back analysis identified treat-and-release ED visits in the month prior to sepsis hospitalizations. Top 20 diagnoses associated with these ED visits were identified; two diagnosis categories were distinguished as being linked to downstream sepsis hospitalizations. Observed-to-expected (O:E) and temporal analyses were performed to validate the symptom selection; results were contrasted to a comparison group. Demographics of patients that did and did not experience sepsis misdiagnosis were compared. RESULTS: There were 3,468 sepsis hospitalizations during the study period and 766 treat-and-release ED visits in the month prior to hospitalization. Patients discharged from the ED with fluid and electrolyte disorders (FED) and altered mental status (AMS) were most likely to have downstream sepsis hospitalizations (O:E ratios of 2.66 and 2.82, respectively). Temporal analyses revealed that these symptoms were overrepresented and temporally clustered close to the hospitalization date. Approximately 2% of sepsis hospitalizations were associated with prior FED or AMS ED visits. CONCLUSIONS: Treat-and-release ED encounters for FED and AMS may represent harbingers for downstream sepsis hospitalizations. The SPADE approach can be used to develop performance measures that identify pre-sepsis.

Patient Safety in Primary Care: Conceptual Meanings to the Health Care Team and Patients.

INTRODUCTION: Patient safety in primary care is an emerging priority, and experts have highlighted medications, diagnoses, transitions, referrals, and testing as key safety domains. This study aimed to (1) describe how frontline clinicians, administrators, and staff conceptualize patient safety in primary care; and (2) compare and contrast these conceptual meanings from the patient's perspective. METHODS: We conducted interviews with 101 frontline clinicians, administrators and staff, and focus groups with 65 adult patients at 10 patient-centered medical homes. We used thematic analysis to approach coding. RESULTS: Findings indicate that frontline personnel conceptualized patient safety more in terms of work functions, which reflect the grouping of tasks or responsibilities to guide how care is being delivered. Frontline personnel and patients conceptualized patient safety in largely consistent ways. DISCUSSION: Function-based conceptualizations of patient safety in primary care may better reflect frontline personnel and patients' experiences than domain-based conceptualizations, which are favored by experts.

Social Support Moderates the Negative Association Between Reduced Driving and Life Satisfaction in Older Adults.

When older adults reduce their driving, there can be subsequent decreases in life satisfaction. In this cross-sectional study, we used baseline data from the multi-site Longitudinal Research on Aging Drivers (LongROAD) study to examine whether social support moderates the negative association between reduced driving and life satisfaction. The outcome variable was life satisfaction, and the main predictor variable was past-year reduced driving (yes/no). Emotional, instrumental, and informational social support were measured using PROMIS v2.0 (Patient-Reported Outcomes Measurement Information System) items. We used generalized linear regression models to examine how social support moderated the association between reduced driving and life satisfaction. Statistical adjustment for social support attenuated the negative effect of reduced driving on life satisfaction by ~10% for all three types of social support.

Understanding CancelRx: Results of End-to-End Functional Testing, Proactive Risk Assessment, and Pilot Implementation.

BACKGROUND: CancelRx allows prescribers to send electronic cancellation messages to pharmacies when medications are discontinued. Little is known about its functionality and impact on clinical workflows. OBJECTIVES: To understand CancelRx functionality, its potential impact on workflows and medication safety risks, and to develop mitigating strategies for risks introduced by implementation. METHODS: We conducted direct observations and semi-structured interviews to develop CancelRx use cases and assessed CancelRx in an end-to-end test environment, proactive risk assessment, and pilot implementation from April 16 to July 15, 2018. RESULTS: E-cancellations were sent upon discontinuation of e-prescriptions written within the electronic health record (EHR), but not other medications (e.g., printed prescriptions) and could be initiated by nonprescribers. In our proactive risk assessment, CancelRx implementation eliminated five of seven failure modes in outpatient prescribing to Johns Hopkins pharmacies, but introduced new risks, including (1) failure to act if an e-cancellation was not sent or was unsuccessful; (2) failure to cancel all prescriptions for a medication; (3) errors in manual matching; and (4) erroneous medication cancellations. We identified potential mitigation strategies for these risks. During pilot implementation, 92.4% (428/463) of e-cancellations had confirmed approval by the receiving pharmacy, while 4.5% (21/463) were denied, and 3.0% (14/463) had no e-cancellation response. Among e-cancellations received by the pilot pharmacy, 1.7% (7/408) required manual matching by pharmacy staff. Based on performance in testing, 73.4% (340/463) of completed e-cancellations would be expected to generate an in-basket message, including 21 (6.2%) denials and 319/340 (93.8%) approvals with a note from the pharmacy. CONCLUSION: CancelRx is an important functionality with the potential to decrease adverse events due to medication errors. However, changes in implementation in our EHR and pharmacy software and enhancements in the CancelRx standard are needed to maximize safety and usability. Further studies are needed to evaluate the impact of e-cancellation on medication safety.

Preparing Older Patients With Serious Illness for Advance Care Planning Discussions in Primary Care.

CONTEXT: Little is known about how to prepare older patients for advance care planning (ACP) discussions in primary care. OBJECTIVES: The objective of the study was to explore older patients' perspectives and experiences on ACP discussions with family members and/or primary care clinicians. METHODS: We conducted a qualitative interview study with 20 older patients who were involved in the clinic's ACP quality improvement initiative. We used an inductive approach to generate a coding scheme and used thematic analysis alongside a constant comparative methodology to iteratively refine emergent themes after coding the data. We used the transtheoretical behavior change model to conceptualize the process of ACP discussions, focusing on the contemplation, preparation, and action stages. RESULTS: Four key themes emerged from our analyses: 1) the relevance/importance of ACP as a whole; 2) independently conceptualizing wishes and preferences for the future; 3) the process of engagement in ACP discussions; and 4) different outcomes of ACP discussions. While patients contemplated having an ACP discussion, they needed time to conceptualize their wishes on their own before documenting wishes or engaging with others. Moving to the preparation stage, patients shared their perspectives about how to engage family members and primary care clinicians in ACP discussions and reported different outcomes of these discussions, which varied according to patients' goals for ACP. CONCLUSION: Understanding how to best prepare patients for ACP discussions from patients enrolled in an ACP primary clinic quality improvement initiative may assist primary care practices in developing interventions to improve the occurrence and effectiveness of such discussions.

Obesity, Diabetes, and the Risk of Invasive Group B Streptococcal Disease in Nonpregnant Adults in the United States.

BACKGROUND: Rates of invasive group B Streptococcus (GBS) disease, obesity, and diabetes have increased in US adults. We hypothesized that obesity would be independently associated with an increased risk of invasive GBS disease. METHODS: We identified adults with invasive GBS disease within Active Bacterial Core surveillance during 2010-2012 and used population estimates from the Behavioral Risk Factor Surveillance System to calculate invasive GBS incidence rates. We estimated relative risks (RRs) of invasive GBS using Poisson analysis with offset denominators, with obesity categorized as class I/II (body mass index [BMI] = 30-39.9 kg/m2) and class III (BMI ≥ 40.0 kg/m2). RESULTS: In multivariable analysis of 4281 cases, the adjusted RRs of invasive GBS disease were increased for obesity (class I/II: RR, 1.52; 95% confidence interval [CI], 1.14-2.02; and class III: RR, 4.87; 95% CI, 3.50-6.77; reference overweight) and diabetes (RR, 6.04; 95% CI, 4.77-7.65). The adjusted RR associated with class III obesity was 3-fold among persons with diabetes (95% CI, 1.38-6.61) and nearly 9-fold among persons without diabetes (95% CI, 6.41-12.46), compared with overweight. The adjusted RRs associated with diabetes varied by age and BMI, with the highest RR in young populations without obesity. Population attributable risks of invasive GBS disease were 27.2% for obesity and 40.1% for diabetes. CONCLUSIONS: Obesity and diabetes were associated with substantially increased risk of infection from invasive GBS. Given the population attributable risks of obesity and diabetes, interventions that reduce the prevalence of these conditions would likely reduce the burden of invasive GBS infection.

Team-Based Health Information Exchange Use Increased Mammography Documentation and Referral in an Academic Primary Care Practice: An Interrupted Time Series.

BACKGROUND: Few studies have examined the impact of health information exchanges (HIE) on quality in ambulatory settings. METHODS: From September 29, 2014, to September 4, 2015, we conducted an interrupted time series analysis of query-based use of the state HIE as part of team-based care to improve mammography screening in an academic primary care practice. Women aged 50-74 years with a practice visit and who were eligible for mammography were included. We conducted non-parametric data analysis using LOESS, followed by ARIMA analysis. RESULTS: During the study period, there were 2020 visits among 904 eligible patients, including 648 visits among 485 patients during 16 baseline weeks, and 1372 visits by 755 patients during 33 intervention weeks. During the intervention period, 16.0% of eligible women who were not up to date in our EHR had a mammogram in the HIE. Of eligible women, the proportion who had a documented up-to-date mammogram at the time of their visit increased by 11.3%, from 73.4% at baseline to 84.7% (p < 0.0001), the proportion who had mammography addressed at the time of their visit increased by 42.7%, from 32.7% at baseline to 75.4% (p < 0.0001), and the proportion who were up to date at 8 weeks post-visit increased by 11.7%, from 76.3% at baseline to 88.0% (p < 0.0001). DISCUSSION: Query-based use of the state HIE as part of team-based care improved documentation of mammography and led to an increase in the proportion of eligible women who received counseling on mammography screening in one primary care practice. These results suggest that HIE use in primary care could lead to improved delivery of other preventive services.

Implementing the Comprehensive Unit-Based Safety Program (CUSP) to Improve Patient Safety in an Academic Primary Care Practice.

BACKGROUND: While there is growing awareness of the risk of harm in ambulatory health care, most patient safety efforts have focused on the inpatient setting. The Comprehensive Unit-based Safety Program (CUSP) has been an integral part of highly successful safety efforts in inpatient settings. In 2014 CUSP was implemented in an academic primary care practice. METHODS: As part of CUSP implementation, staff and clinicians underwent training on the science of safety and completed a two-question safety assessment survey to identify safety concerns in the practice. The concerns identified by team members were used to select two initial safety priorities. The impact of CUSP on safety climate and teamwork was assessed through a pre-post comparison of results on the validated Safety Attitudes Questionnaire. RESULTS: Ninety-six percent of staff completed science of safety training as part of CUSP implementation, and 100% of staff completed the two-question safety assessment. The most frequently identified safety concerns were related to medications (n = 11, 28.2), diagnostic testing (n = 9, 25), and communication (n = 5, 14). The CUSP team initially prioritized communication and infection control, which led to standardization of work flows within the practice. Six months following CUSP implementation, large but nonstatistically significant increases were found for the percentage of survey respondents who reported knowledge of the proper channels for questions about patient safety, felt encouraged to report safety concerns, and believed that the work setting made it easy to learn from the errors of others. CONCLUSION: CUSP is a promising tool to improve safety climate and to identify and address safety concerns within ambulatory health care.
