The Prevalence of Chronic Diseases and Multimorbidity in Primary Care Practice: A PPRNet Report

Introduction: Multimorbidity (multiple chronic illnesses) greatly affects the delivery of health care and assessment of health care quality. There is a lack of basic epidemiologic data on multimorbidity in the United States. This article addresses the prevalence of 24 chronic illnesses and multimorbidity from primary care practices across the United States. Methods: This cross-sectional study was conducted in the PPRNet, a practice-based research network among 226 practices in 43 states that maintains a clinical database derived from a common electronic health record. Practices providing data as of October 1, 2011, and their active adult patients comprised the population used for analyses. The prevalence of each chronic illness and multimorbidity were calculated. Results: Included in these analyses were 148 practices with 667,379 active patients. Median prevalence across practices ranged from 35.8% for hypertension to 0.23% for Parkinson disease, with wide variability among practices for all conditions. Multimorbidity increased steeply with age, leveling off at age 80; overall, 45.2% of patients had more than one chronic illness. Conclusion: Multimorbidity is a prevalent problem in primary care practice, a finding with implications for health care delivery and payment, quality assessment, and research.

The Use of Clinical Decision‐Support Tools to Facilitate Geriatric Education

Innovative methods are needed to incorporate effective geriatric education into internal medicine residency programs. The purpose of this report is to describe the development and use of clinical decision‐support (CDS) tools to facilitate geriatric education and improve the care delivered to older adults in an academic internal medicine residency ambulatory care clinic. Starting in 2009, CDS tools were implemented as a major strategy of an initiative to improve resident physician clinical competencies in geriatrics and improve the quality of care and quality of life of older adults. These tools, designed to improve resident assessment and action for each of three educational modules (falls, vision, and dementia) were embedded within the ambulatory electronic medical record (EMR) and provided a method of point‐of‐care training to residents caring for older adults. One hundred internal medicine residents supervised by 17 general internal medicine faculty members participated. Data regarding CDS use and associated outcomes were recorded and extracted from the ambulatory clinic EMR. Residents screened between 67% and 88% of eligible patients using CDS algorithms; rates of additional assessment and referral or further examination reflected the prevalence of the condition in the patient population. Although further development may be necessary, CDS tools are a promising modality to supplement geriatric postgraduate education while simultaneously improving patient care.

Preventive Services Delivery in Patients With Chronic Illnesses: Parallel Opportunities Rather Than Competing Obligations

PURPOSE Whether patients with 1 or more chronic illnesses are more or less likely to receive recommended preventive services is unclear and an important public health and health care system issue. We addressed this issue in a large national practice-based research network (PBRN) that maintains a longitudinal database derived from electronic health records. METHODS We conducted a cross-sectional study as of October 1, 2011, of the association between being up to date with 10 preventive services and the prevalence of 24 chronic illnesses among 667,379 active patients aged 18 years or older in 148 member practices in a national PBRN. We used generalized linear mixed models to assess for the association of being up to date with each preventive service as a function of the patient’s number of chronic conditions, adjusted for patient age and encounter frequency. RESULTS Of the patients 65.4% had at least 1 of the 24 chronic illnesses. For 9 of the 10 preventive services there were strong associations between the odds of being up to date and the presence of chronic illness, even after adjustment for visit frequency and patient age. Odds ratios increased with the number of chronic conditions for 5 of the preventive services. CONCLUSIONS Rather than a barrier, the presence of chronic illness was positively associated with receipt of recommended preventive services in this large national PBRN. This finding supports the notion that modern primary care practice can effectively deliver preventive services to the growing number of patients with multiple chronic illnesses.

Quality indicators for primary care: an example for chronic kidney disease.

Although clinical guidelines exist for the management of chronic kidney disease, there is some evidence that care provided by primary care physicians is not concordant with these guidelines. To translate guidelines into practice, a set of quality indicators that are valid and feasible is needed. In this study, which was conducted in PPRNet in 2011, a consensus process was used to develop a set of 12 face valid and reliable quality indicators that can be utilized by primary care physicians to measure and improve chronic kidney disease management.

Medication Safety in Primary Care Practice Results From a PPRNet Quality Improvement Intervention

Reducing medication errors is a fundamental patient safety goal; however, few improvement interventions have been evaluated in primary care settings. The Medication Safety in Primary Care Practice project was designed to test the impact of a multimethod quality improvement intervention on 5 categories of preventable prescribing and monitoring errors in 20 Practice Partner Research Network (PPRNet) practices. PPRNet is a primary care practice–based research network among users of a common electronic health record (EHR). The intervention was associated with significant improvements in avoidance of potentially inappropriate therapy, potential drug-disease interactions, and monitoring of potential adverse events over 2 years. Avoidance of potentially inappropriate dosages and drug-drug interactions did not change over time. Practices implemented a variety of medication safety strategies that may be relevant to other primary care audiences, including use of EHR-based audit and feedback reports, medication reconciliation, decision-support tools, and refill protocols.
