Impact of electronic health record clinical decision support on diabetes care: a randomized trial

PURPOSE We wanted to assess the impact of an electronic health record–based diabetes clinical decision support system on control of hemoglobin A_1c (glycated hemoglobin), blood pressure, and low-density lipoprotein (LDL) cholesterol levels in adults with diabetes.METHODS We conducted a clinic-randomized trial conducted from October 2006 to May 2007 in Minnesota. Included were 11 clinics with 41 consenting primary care physicians and the physicians’ 2,556 patients with diabetes. Patients were randomized either to receive or not to receive an electronic health record (EHR)–based clinical decision support system designed to improve care for those patients whose hemoglobin A_1c, blood pressure, or LDL cholesterol levels were higher than goal at any office visit. Analysis used general and generalized linear mixed models with repeated time measurements to accommodate the nested data structure.RESULTS The intervention group physicians used the EHR-based decision support system at 62.6% of all office visits made by adults with diabetes. The intervention group diabetes patients had significantly better hemoglobin A_1c (intervention effect −0.26%; 95% confidence interval, −0.06% to −0.47%; P=.01), and better maintenance of systolic blood pressure control (80.2% vs 75.1%, P=.03) and borderline better maintenance of diastolic blood pressure control (85.6% vs 81.7%, P =.07), but not improved low-density lipoprotein cholesterol levels (P = .62) than patients of physicians randomized to the control arm of the study. Among intervention group physicians, 94% were satisfied or very satisfied with the intervention, and moderate use of the support system persisted for more than 1 year after feedback and incentives to encourage its use were discontinued.CONCLUSIONS EHR-based diabetes clinical decision support significantly improved glucose control and some aspects of blood pressure control in adults with type 2 diabetes.     

The relationship between primary health care organization and quality of diabetes care

Abstract

Background: Despite many quality improvement trials, diabetes care often remains suboptimal. Few studies in a primary care setting have investigated the ‘real life’ association between organizational differences and quality of diabetes care. Methods: Observational study among ten health care centres with a total of 45 general practitioners (GP). We investigated health care organization and related this to quality of care in a total of 1849 electronic patient records. Results: There were large differences among health care centres in the percentage of patients receiving optimal care (range: 8–67%). The odds to receive good quality of care was higher if the health care centre had a diabetes education program (OR: 4.3; CI: 3.4–5.4), when yearly medical check-ups were done by both the GP and nurse practitioner (NP) (OR: 5.5; CI: 4.2–7.3), planned that after the patient visited the NP the patient is discussed with the GP (OR: 1.8; CI: 1.6–2.0), and had structured follow-up measures for compliance to check-ups (OR: 0.7; CI: 0.5–0.9 and OR: 0.59; CI: 0.5–0.7 for respectively one and two active measures compared to three active measures).

Conclusion: Also in real life, quality of care for type 2 diabetic patients is related to health care organization.     

Problems with the electronic health record

One of the most significant changes in modern healthcare delivery has been the evolution of the paper record to the electronic health record (EHR). In this paper we argue that the primary change has been a shift in the focus of documentation from monitoring individual patient progress to recording data pertinent to Institutional Priorities (IPs). The specific IPs to which we refer include: finance/reimbursement; risk management/legal considerations; quality improvement/safety initiatives; meeting regulatory and accreditation standards; and patient care delivery/evidence based practice. Following a brief history of the transition from the paper record to the EHR, the authors discuss unintended or contested consequences resulting from this change. These changes primarily reflect changes in the organization and amount of clinician work and clinician‐patient relationships. The paper is not a research report but was informed by an institutional ethnography the aim of which was to understand how the EHR impacted clinicians and administrators in a large, urban hospital in the United States. The paper was also informed by other sources, including the philosophies of Jacques Ellul, Don Idhe, and Langdon Winner.

An educational intervention to improve data recording in the management of ischaemic heart disease in primary care

BACKGROUND: Gaps in computerized medical records and a lack of a systematic approach to data recording make progress towards achieving quality standards in primary care difficult to demonstrate. The aim of this study was to examine the effect of an educational intervention on data quality in primary care. METHODS: A before-and-after study of key data quality measures was carried out in 87 general practices in eight primary care organizations in England in phase 1 and 84 general practices in phase 2. The subjects were 19,470 patients with ischaemic heart disease in phase 1 and 19,784 patients in phase 2. The main outcome measures were improvement in the completeness and quality of the computerized medical record. Anonymized data were extracted from clinical information systems and processed to produce comparative information on each practice. Data quality workshops were arranged, in which reflection can take place, backed up by summary statistics. Practice visits provided training and personalized feedback of patients needing intervention. RESULTS: In the patients with heart disease, nearly 16,000 new clinical entries were made in the key improvement areas. The percentage of patients advised to quit smoking increased by 49.3 per cent, from 23.6 per cent to 61.9 per cent. There were also significant improvements in many other aspects of management. CONCLUSION: Focused interventions that provide targeted and relevant clinical information can be implemented in primary care. Such interventions can lead to a rise in data quality in primary care, but their effectiveness needs to be further tested in more rigorous research settings such as randomized controlled trials.

Research evidence on strategies enabling integration of electronic health records in the health care systems of low‐ and middle‐income countries: A literature review

Integration of electronic health records (EHRs) in the national health care systems of low‐ and middle‐income countries (LMICs) is vital for achieving the United Nations Sustainable Development Goal of ensuring healthy lives and promoting well‐being for all people of all ages. National EHR systems are increasing, but mostly in developed countries. Besides, there is limited research evidence on successful strategies for ensuring integration of national EHRs in the health care systems of LMICs. To fill this evidence gap, a comprehensive survey of literature was conducted using scientific electronic databases—PubMed, SCOPUS, Web of Science, and Global Health—and consultations with international experts. The review highlights the lack of evidence on strategies for integrating EHR systems, although there was ample evidence on implementation challenges and relevance of EHRs to vertical disease programs such as HIV. The findings describe the narrow focus of EHR implementation, the prominence of vertical disease programs in EHR adoption, testing of theoretical and conceptual models for EHR implementation and success, and strategies for EHR implementation. The review findings are further amplified through examples of EHR implementation in Sierra Leone, Malawi, and India. Unless evidence‐based strategies are identified and applied, integration of national EHRs in the health care systems of LMICs is difficult.     

Variation in how mothers, health visitors and general practitioners use the personal child health record

BACKGROUND: In the UK, a national personal child health record (PCHR) with local adaptations is in widespread use. Previous studies report that parents find the PCHR useful and that health visitors use it more than other health professionals. This study was carried out in Nottingham, where the local PCHR is similar to the national PCHR. OBJECTIVES: To explore variation in use of the PCHR made by mothers with differing social characteristics, to compare heath visitors' and general practitioners' (GPs') use of the PCHR, and to compare health visitors' and GPs' perceptions of the PCHR with those of mothers for whose children they provide care. METHODS: Questionnaires to 534 parents registered with 28 general practices and interviews with a health visitor and GP at each practice. A score per mother for perceived usefulness of the PCHR was developed from the questionnaire, and variation in the score was investigated by linear regression adjusted for clustering. RESULTS: Four hundred and one (75%) questionnaires were returned. Three hundred and twenty-five (82%) mothers thought the PCHR was very good or good. Higher scores for usage of the PCHR were significantly associated with teenage and first-time mothers, but no association was found with mother's social class, education or being a single parent. There was no association between variation in the score and practice, health visitor or GP characteristics. Mothers, health visitors and GPs reported that mothers took the PCHR to baby clinic more frequently than when seeing their GP, and that health visitors wrote in the PCHR more frequently than GPs. Eighteen (67%) health visitors and 20 (71%) GPs said they had difficulty recording information in the PCHR. CONCLUSION: The PCHR is used by most mothers and is important for providing health promotion material to all families with young children. It may be particularly useful for first-time and teenage mothers.     

Electronic health records vs Medicaid claims: completeness of diabetes preventive care data in community health centers

PURPOSE Electronic Health Record (EHR) databases in community health centers (CHCs) present new opportunities for quality improvement, comparative effectiveness, and health policy research. We aimed (1) to create individual-level linkages between EHR data from a network of CHCs and Medicaid claims from 2005 through 2007; (2) to examine congruence between these data sources; and (3) to identify sociodemographic characteristics associated with documentation of services in one data set vs the other.METHODS We studied receipt of preventive services among established diabetic patients in 50 Oregon CHCs who had ever been enrolled in Medicaid (N = 2,103). We determined which services were documented in EHR data vs in Medicaid claims data, and we described the sociodemographic characteristics associated with these documentation patterns.RESULTS In 2007, the following services were documented in Medicaid claims but not the EHR: 11.6% of total cholesterol screenings received, 7.0% of total influenza vaccinations, 10.5% of nephropathy screenings, and 8.8% of tests for glycated hemoglobin (HbA_1c). In contrast, the following services were documented in the EHR but not in Medicaid claims: 49.3% of cholesterol screenings, 50.4% of influenza vaccinations, 50.1% of nephropathy screenings, and 48.4% of HbA_1c tests. Patients who were older, male, Spanish-speaking, above the federal poverty level, or who had discontinuous insurance were more likely to have services documented in the EHR but not in the Medicaid claims data.CONCLUSIONS Networked EHRs provide new opportunities for obtaining more comprehensive data regarding health services received, especially among populations who are discontinuously insured. Relying solely on Medicaid claims data is likely to substantially underestimate the quality of care.     

Failure of Internet-based audit and feedback to improve quality of care delivered by primary care residents.

OBJECTIVE: To determine the effectiveness of Internet-based audit and feedback to physicians to improve care for diabetes and hypertension. DESIGN: Time-series analysis of an intervention. METHODS: The study setting was Harvard Vanguard Medical Associates, a 14-site multispecialty group in greater Boston. The study period was July 1997-June 1999. PARTICIPANTS: were 12 primary care internal medicine residents who provided care to adult patients with diabetes (n = 76 pre-intervention and n = 88 post-intervention), hypertension (n = 329 pre-intervention and n = 338 post-intervention), or both (n = 62 pre-intervention and n = 71 post-intervention). We determined the proportion of each resident's patients whose care fulfilled national guidelines for quality (i.e. diabetes patients had hemoglobin testing in the previous 6 months or hypertension patients received a beta-blocker or diuretic in the same time period). After meeting individually with each resident to obtain informed consent and to encourage participation, we sent each resident information for accessing his or her practice profile on a secure website. The main outcome measures were (i) the proportion of resident physicians who accessed their profiles and (ii) change following the intervention in the proportion of patients whose care followed national guidelines. RESULTS: Over a 1-year period, only four of the 12 residents accessed their websites. One of the residents visited her site three times, while the other three residents visited their sites once each. In interrupted time-series analyses, the intervention had no discernible effect on adherence to practice guidelines for diabetes or hypertension. CONCLUSION: The lack of participation in this Internet-based intervention may have important implications for the development of future programs that require physicians to interact with technology to improve quality of care.     

Quality of life among diabetic patients in Swedish primary health care and in the general population: comparison between 1992 and 1995

To assess change over time in health-related quality of life (HRQoL) in diabetic patients in primary health care and differences to general Swedish population samples, 341 diabetic subjects in 1992 and 413 in 1995, aged 20–84 years, were chosen from three community health centres (CHCs) in the Metropolitan Stockholm area and compared to controls matched by age and sex in randomly selected samples of 2,366 subjects in 1991 and 2,500 in 1995 from the general population. HRQoL was assessed by the Swedish Health-Related Quality of Life Survey (SWED-QUAL), adapted from the Medical Outcomes Study, which measures aspects of physical, mental, social and general health in 13 scales. Information on diabetic and general medical data were extracted from the medical records at the CHCs. HRQoL was lower in diabetic subjects compared with the general population in both 1992 and 1995 in all scales except family functioning and marital functioning. The level of HRQoL did not change significantly between the diabetic samples, but decreased in the population samples, making the difference compared to diabetic patients smaller in five of the scales. The most significant predicting factors for the SWED-QUAL results in diabetic patients in 1995 were the vascular and non-vascular co-morbidity.

Assessing the quality of preschool child health surveillance in primary care: a pilot study in one health district

OBJECTIVE: To develop a framework for measuring the quality of preschool child health surveillance acceptable to primary health care teams and measurable at individual primary health care team level. DESIGN: Published research evidence was identified and criteria developed by a local multidisciplinary expert group. The criteria were discussed with primary health care teams. How well they were achieved was assessed. SETTING: Twenty-eight general practices in one health authority area. METHODS: Data collection included observation of baby clinics, interviews with health visitors and general practitioners (GPs), questionnaires to parents, collation of child health surveillance reviews recorded in personal child health records and immunization rates. RESULTS: The criteria for assessing preschool child health surveillance were thought to be acceptable and achievable by primary health care teams. Fifteen of the 22 criteria used to assess baby clinics were met by over 90 of practices. Almost all practices completed child health surveillance reviews within a standard time and achieved 90 coverage for primary immunizations. At many practices, less than 90 of parents felt welcome at the baby clinic, usually had enough time to talk to their health visitor or had the purpose or results of the 6 to 8 week child health surveillance review explained to them. GPs were less likely than health visitors to discuss health promotion at child health surveillance reviews (chi(2) 11.52, P = 0.0007). Few practices had a call-up and recall system for all reviews. CONCLUSION: The framework that we developed for assessing preschool child health surveillance was acceptable and achievable by primary health care teams.
