Requiring physicians to respond to computerized reminders improves their compliance with preventive care protocols

Value of Electronic Health Records Measured Using Financial and Clinical Outcomes: Quantitative Study

BACKGROUND

The Health Information Technology for Economic and Clinical Health Act of 2009 was legislated to reduce health care costs, improve quality, and increase patient safety. Providers and organizations were incentivized to exhibit meaningful use of certified electronic health record (EHR) systems in order to achieve this objective. EHR adoption is an expensive investment, given the resources and capital that are invested. Due to the cost of the investment, a return on the EHR adoption investment is expected.

OBJECTIVE

This study performed a value analysis of EHRs. The objective of this study was to investigate the relationship between EHR adoption levels and financial and clinical outcomes by combining both financial and clinical outcomes into one conceptual model.

METHODS

We examined the multivariate relationships between different levels of EHR adoption and financial and clinical outcomes, along with the time variant control variables, using moderation analysis with a longitudinal fixed effects model. Since it is unknown as to when hospitals begin experiencing improvements in financial outcomes, additional analysis was conducted using a 1- or 2-year lag for profit margin ratios.

RESULTS

A total of 5768 hospital-year observations were analyzed over the course of 4 years. According to the results of the moderation analysis, as the readmission rate increases by 1 unit, the effect of a 1-unit increase in EHR adoption level on the operating margin decreases by 5.38%. Hospitals with higher readmission payment adjustment factors have lower penalties.

CONCLUSIONS

This study fills the gap in the literature by evaluating individual relationships between EHR adoption levels and financial and clinical outcomes, in addition to evaluating the relationship between EHR adoption level and financial outcomes, with clinical outcomes as moderators. This study provided statistically significant evidence (P<.05), indicating that there is a relationship between EHR adoption level and operating margins when this relationship is moderated by readmission rates, meaning hospitals that have adopted EHRs could see a reduction in their readmission rates and an increase in operating margins. This finding could further be supported by evaluating more recent data to analyze whether hospitals increasing their level of EHR adoption would decrease readmission rates, resulting in an increase in operating margins. Hospitals would incur lower penalties as a result of improved readmission rates, which would contribute toward improved operating margins.

Testing the Accuracy of a Bedside Screening Tool Framework to Clinical Records for Identification of Patients at Risk of Malnutrition in a Rural Setting: An Exploratory Study

This study aimed to explore the diagnostic accuracy of the Patient-Generated Subjective Global Assessment (PG-SGA) malnutrition risk screening tool when used to score patients based on their electronic medical records (EMR), compared to bedside screening interviews. In-patients at a rural health service were screened at the bedside (n = 50) using the PG-SGA, generating a bedside score. Clinical notes within EMRs were then independently screened by blinded researchers. The accuracy of the EMR score was assessed against the bedside score using area under the receiver operating curve (AUC), sensitivity, and specificity. Participants were 62% female and 32% had conditions associated with malnutrition, with a mean age of 70.6 years (SD 14.9). The EMR score had moderate diagnostic accuracy relative to PG-SGA bedside screen, AUC 0.74 (95% CI: 0.59–0.89). The accuracy, specificity and sensitivity of the EMR score was highest for patients with a score of 7, indicating EMR screen is more likely to detect patients at risk of malnutrition. This exploratory study showed that applying the PG-SGA screening tool to EMRs had enough sensitivity and specificity for identifying patients at risk of malnutrition to warrant further exploration in low-resource settings.

Interventions targeted at women to encourage the uptake of cervical screening

BACKGROUND

This is an update of the Cochrane review published in Issue 5, 2011. Worldwide, cervical cancer is the fourth commonest cancer affecting women. High-risk human papillomavirus (HPV) infection is causative in 99.7% of cases. Other risk factors include smoking, multiple sexual partners, the presence of other sexually transmitted diseases and immunosuppression. Primary prevention strategies for cervical cancer focus on reducing HPV infection via vaccination and data suggest that this has the potential to prevent nearly 90% of cases in those vaccinated prior to HPV exposure. However, not all countries can afford vaccination programmes and, worryingly, uptake in many countries has been extremely poor. Secondary prevention, through screening programmes, will remain critical to reducing cervical cancer, especially in unvaccinated women or those vaccinated later in adolescence. This includes screening for the detection of pre-cancerous cells, as well as high-risk HPV. In the UK, since the introduction of the Cervical Screening Programme in 1988, the associated mortality rate from cervical cancer has fallen. However, worldwide, there is great variation between countries in both coverage and uptake of screening. In some countries, national screening programmes are available whereas in others, screening is provided on an opportunistic basis. Additionally, there are differences within countries in uptake dependent on ethnic origin, age, education and socioeconomic status. Thus, understanding and incorporating these factors in screening programmes can increase the uptake of screening. This, together with vaccination, can lead to cervical cancer becoming a rare disease.

OBJECTIVES

To assess the effectiveness of interventions aimed at women, to increase the uptake, including informed uptake, of cervical screening.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), Issue 6, 2020. MEDLINE, Embase and LILACS databases up to June 2020. We also searched registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field.

SELECTION CRITERIA

Randomised controlled trials (RCTs) of interventions to increase uptake/informed uptake of cervical screening.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed risk of bias. Where possible, the data were synthesised in a meta-analysis using standard Cochrane methodology.

MAIN RESULTS

Comprehensive literature searches identified 2597 records; of these, 70 met our inclusion criteria, of which 69 trials (257,899 participants) were entered into a meta-analysis. The studies assessed the effectiveness of invitational and educational interventions, lay health worker involvement, counselling and risk factor assessment. Clinical and statistical heterogeneity between trials limited statistical pooling of data. Overall, there was moderate-certainty evidence to suggest that invitations appear to be an effective method of increasing uptake compared to control (risk ratio (RR) 1.71, 95% confidence interval (CI) 1.49 to 1.96; 141,391 participants; 24 studies). Additional analyses, ranging from low to moderate-certainty evidence, suggested that invitations that were personalised, i.e. personal invitation, GP invitation letter or letter with a fixed appointment, appeared to be more successful. More specifically, there was very low-certainty evidence to support the use of GP invitation letters as compared to other authority sources' invitation letters within two RCTs, one RCT assessing 86 participants (RR 1.69 95% CI 0.75 to 3.82) and another, showing a modest benefit, included over 4000 participants (RR 1.13, 95 % CI 1.05 to 1.21). Low-certainty evidence favoured personalised invitations (telephone call, face-to-face or targeted letters) as compared to standard invitation letters (RR 1.32, 95 % CI 1.11 to 1.21; 27,663 participants; 5 studies). There was moderate-certainty evidence to support a letter with a fixed appointment to attend, as compared to a letter with an open invitation to make an appointment (RR 1.61, 95 % CI 1.48 to 1.75; 5742 participants; 5 studies). Low-certainty evidence supported the use of educational materials (RR 1.35, 95% CI 1.18 to 1.54; 63,415 participants; 13 studies) and lay health worker involvement (RR 2.30, 95% CI 1.44 to 3.65; 4330 participants; 11 studies). Other less widely reported interventions included counselling, risk factor assessment, access to a health promotion nurse, photo comic book, intensive recruitment and message framing. It was difficult to deduce any meaningful conclusions from these interventions due to sparse data and low-certainty evidence. However, having access to a health promotion nurse and attempts at intensive recruitment may have increased uptake. One trial reported an economic outcome and randomised 3124 participants within a national screening programme to either receive the standard screening invitation, which would incur a fee, or an invitation offering screening free of charge. No difference in the uptake at 90 days was found (574/1562 intervention versus 612/1562 control, (RR 0.94, 95% CI: 0.86 to 1.03). The use of HPV self-testing as an alternative to conventional screening may also be effective at increasing uptake and this will be covered in a subsequent review. Secondary outcomes, including cost data, were incompletely documented. The majority of cluster-RCTs did not account for clustering or adequately report the number of clusters in the trial in order to estimate the design effect, so we did not selectively adjust the trials. It is unlikely that reporting of these trials would impact the overall conclusions and robustness of the results. Of the meta-analyses that could be performed, there was considerable statistical heterogeneity, and this should be borne in mind when interpreting these findings. Given this and the low to moderate evidence, further research may change these findings. The risk of bias in the majority of trials was unclear, and a number of trials suffered from methodological problems and inadequate reporting. We downgraded the certainty of evidence because of an unclear or high risk of bias with regards to allocation concealment, blinding, incomplete outcome data and other biases.

AUTHORS' CONCLUSIONS

There is moderate-certainty evidence to support the use of invitation letters to increase the uptake of cervical screening. Low-certainty evidence showed lay health worker involvement amongst ethnic minority populations may increase screening coverage, and there was also support for educational interventions, but it is unclear what format is most effective. The majority of the studies were from developed countries and so the relevance of low- and middle-income countries (LMICs), is unclear. Overall, the low-certainty evidence that was identified makes it difficult to infer as to which interventions were best, with exception of invitational interventions, where there appeared to be more reliable evidence.

Design, development, and deployment of an indication- and kidney function-based decision support tool to optimize treatment and reduce medication dosing errors

Delivering clinical decision support (CDS) at the point of care has long been considered a major advantage of computerized physician order entry (CPOE). Despite the widespread implementation of CPOE, medication ordering errors and associated adverse events still occur at an unacceptable level. Previous attempts at indication- and kidney function-based dosing have mostly employed intrusive CDS, including interruptive alerts with poor usability. This descriptive work describes the design, development, and deployment of the Adult Dosing Methodology (ADM) module, a novel CDS tool that provides indication- and kidney-based dosing at the time of order entry. Inclusion of several antimicrobials in the initial set of medications allowed for the additional goal of optimizing therapy duration for appropriate antimicrobial stewardship. The CDS aims to decrease order entry errors and burden on providers by offering automatic dose and frequency recommendations, integration within the native electronic health record, and reasonable knowledge maintenance requirements. Following implementation, early utilization demonstrated high acceptance of automated recommendations, with up to 96% of provided automated recommendations accepted by users.

Digitizing U.S. Air Force Medical Standards for the Creation and Validation of a Readiness Decision Support System

INTRODUCTION

Deployment-limiting medical conditions are the primary reason why service members are not medically ready. Service-specific standards guide clinicians in what conditions are restrictive for duty, fitness, and/or deployment requirements. The Air Force (AF) codifies most standards in the Medical Standards Directory (MSD). Providers manually search this document, among others, to determine if any standards are violated, a tedious and error-prone process. Digitized, standards-based decision-support tools for providers would ease this workflow. This study digitized and mapped all AF occupations to MSD occupational classes and all MSD standards to diagnosis codes and created and validated a readiness decision support system (RDSS) around this mapping.

MATERIALS AND METHODS

A medical coder mapped all standards within the May 2018 v2 MSD to 2018 International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) codes. For the publication of new MSDs, we devised an automated update process using Amazon Web Service's Comprehend Medical and the Unified Medical Language System's Metathesaurus. We mapped Air Force Specialty Codes to occupational classes using the MSD and AF classification directories. We uploaded this mapping to a cloud-based MySQL (v5.7.23) database and built a web application to interface with it using R (v3.5+). For validation, we compared the RDSS to the record review of two subject-matter experts (SMEs) for 200 outpatient encounters in calendar year 2018. We performed four separate analyses: (1) SME vs. RDSS for any restriction; (2) SME interrater reliability for any restriction; (3) SME vs. RDSS for specific restriction(s); and (4) SME interrater reliability for categorical restriction(s). This study was approved as "Not Human Subjects Research" by the Air Force Research Laboratory (FWR20190100N) and Boston Children's Hospital (IRB-P00031397) review boards.

RESULTS

Of the 709 current medical standards in the September 2019 MSD, 631 (89.0%) were mapped to ICD-10-CM codes. These 631 standards mapped to 42,810 unique ICD codes (59.5% of all active 2019 codes) and covered 72.3% (7,823/10,821) of the diagnoses listed on AF profiles and 92.8% of profile days (90.7/97.8 million) between February 1, 2007 and January 31, 2017. The RDSS identified diagnoses warranting any restrictions with 90.8% and 90.0% sensitivity compared to SME A and B. For specific restrictions, the sensitivity was 85.0% and 44.8%. The specificity was poor for any restrictions (20.5%-43.4%) and near perfect for specific restrictions (99.5+%). The interrater reliability between SMEs for all comparisons ranged from minimal to moderate (κ = 0.33-0.61).

CONCLUSION

This study demonstrated key pilot steps to digitizing and mapping AF readiness standards to existing terminologies. The RDSS showed one potential application. The sensitivity between the SMEs and RDSS demonstrated its viability as a screening tool with further refinement and study. However, its performance was not evenly distributed by special duty status or for the indication of specific restrictions. With machine consumable medical standards integrated within existing digital infrastructure and clinical workflows, RDSSs would remove a significant administrative burden from providers and likely improve the accuracy of readiness metrics.

Designing, Conducting, and Reporting Clinical Decision Support Studies: Recommendations and Call to Action

By enabling more efficient and effective medical decision making, computer-based clinical decision support (CDS) could unlock widespread benefits from the significant investment in electronic health record (EHR) systems in the United States. Evidence from high-quality CDS studies is needed to enable and support this vision of CDS-facilitated care optimization, but limited guidance is available in the literature for designing and reporting CDS studies. To address this research gap, this article provides recommendations for designing, conducting, and reporting CDS studies to: 1) ensure that EHR data to inform the CDS are available; 2) choose decision rules that are consistent with local care processes; 3) target the right users and workflows; 4) make the CDS easy to access and use; 5) minimize the burden placed on users; 6) incorporate CDS success factors identified in the literature, in particular the automatic provision of CDS as a part of clinician workflow; 7) ensure that the CDS rules are adequately tested; 8) select meaningful evaluation measures; 9) use as rigorous a study design as is feasible; 10) think about how to deploy the CDS beyond the original host organization; 11) report the study in context; 12) help the audience understand why the intervention succeeded or failed; and 13) consider the financial implications. If adopted, these recommendations should help advance the vision of more efficient, effective care facilitated by useful and widely available CDS.

Manually-generated reminders delivered on paper: effects on professional practice and patient outcomes

BACKGROUND

Health professionals sometimes do not use the best evidence to treat their patients, in part due to unconscious acts of omission and information overload. Reminders help clinicians overcome these problems by prompting them to recall information that they already know, or by presenting information in a different and more accessible format. Manually-generated reminders delivered on paper are defined as information given to the health professional with each patient or encounter, provided on paper, in which no computer is involved in the production or delivery of the reminder. Manually-generated reminders delivered on paper are relatively cheap interventions, and are especially relevant in settings where electronic clinical records are not widely available and affordable. This review is one of three Cochrane Reviews focused on the effectiveness of reminders in health care.

OBJECTIVES

1. To determine the effectiveness of manually-generated reminders delivered on paper in changing professional practice and improving patient outcomes. 2. To explore whether a number of potential effect modifiers influence the effectiveness of manually-generated reminders delivered on paper.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, CINAHL and two trials registers on 5 December 2018. We searched grey literature, screened individual journals, conference proceedings and relevant systematic reviews, and reviewed reference lists and cited references of included studies.

SELECTION CRITERIA

We included randomised and non-randomised trials assessing the impact of manually-generated reminders delivered on paper as a single intervention (compared with usual care) or added to one or more co-interventions as a multicomponent intervention (compared with the co-intervention(s) without the reminder component) on professional practice or patients' outcomes. We also included randomised and non-randomised trials comparing manually-generated reminders with other quality improvement (QI) interventions.

DATA COLLECTION AND ANALYSIS

Two review authors screened studies for eligibility and abstracted data independently. We extracted the primary outcome as defined by the authors or calculated the median effect size across all reported outcomes in each study. We then calculated the median percentage improvement and interquartile range across the included studies that reported improvement related outcomes, and assessed the certainty of the evidence using the GRADE approach.

MAIN RESULTS

We identified 63 studies (41 cluster-randomised trials, 18 individual randomised trials, and four non-randomised trials) that met all inclusion criteria. Fifty-seven studies reported usable data (64 comparisons). The studies were mainly located in North America (42 studies) and the UK (eight studies). Fifty-four studies took place in outpatient/ambulatory settings. The clinical areas most commonly targeted were cardiovascular disease management (11 studies), cancer screening (10 studies) and preventive care (10 studies), and most studies had physicians as their target population (57 studies). General management of a clinical condition (17 studies), test-ordering (14 studies) and prescription (10 studies) were the behaviours more commonly targeted by the intervention. Forty-eight studies reported changes in professional practice measured as dichotomous process adherence outcomes (e.g. compliance with guidelines recommendations), 16 reported those changes measured as continuous process-of-care outcomes (e.g. number of days with catheters), eight reported dichotomous patient outcomes (e.g. mortality rates) and five reported continuous patient outcomes (e.g. mean systolic blood pressure). Manually-generated reminders delivered on paper probably improve professional practice measured as dichotomous process adherence outcomes) compared with usual care (median improvement 8.45% (IQR 2.54% to 20.58%); 39 comparisons, 40,346 participants; moderate certainty of evidence) and may make little or no difference to continuous process-of-care outcomes (8 comparisons, 3263 participants; low certainty of evidence). Adding manually-generated paper reminders to one or more QI co-interventions may slightly improve professional practice measured as dichotomous process adherence outcomes (median improvement 4.24% (IQR -1.09% to 5.50%); 12 comparisons, 25,359 participants; low certainty of evidence) and probably slightly improve professional practice measured as continuous outcomes (median improvement 0.28 (IQR 0.04 to 0.51); 2 comparisons, 12,372 participants; moderate certainty of evidence). Compared with other QI interventions, manually-generated reminders may slightly decrease professional practice measured as process adherence outcomes (median decrease 7.9% (IQR -0.7% to 11%); 14 comparisons, 21,274 participants; low certainty of evidence). We are uncertain whether manually-generated reminders delivered on paper, compared with usual care or with other QI intervention, lead to better or worse patient outcomes (dichotomous or continuous), as the certainty of the evidence is very low (10 studies, 13 comparisons). Reminders added to other QI interventions may make little or no difference to patient outcomes (dichotomous or continuous) compared with the QI alone (2 studies, 2 comparisons). Regarding resource use, studies reported additional costs per additional point of effectiveness gained, but because of the different currencies and years used the relevance of those figures is uncertain. None of the included studies reported outcomes related to harms or adverse effects.

AUTHORS' CONCLUSIONS

Manually-generated reminders delivered on paper as a single intervention probably lead to small to moderate increases in outcomes related to adherence to clinical recommendations, and they could be used as a single QI intervention. It is uncertain whether reminders should be added to other QI intervention already in place in the health system, although the effects may be positive. If other QI interventions, such as patient or computerised reminders, are available, they should be preferred over manually-generated reminders, but under close evaluation in order to decrease uncertainty about their potential effect.

Prevalence of pain reports in pediatric primary care and association with demographics, body mass index, and exam findings: a cross-sectional study

BACKGROUND

Pediatric pain is associated to patient weight and demographics in specialized settings, but pain prevalence and its associated patient attributes in general pediatric outpatient care are unknown. Our objective was to determine the rate of positive pain screenings in pediatric primary care and evaluate the relationship between reported pain and obesity, demographics, and exam findings during routine pediatric encounters.

METHODS

Cross-sectional observational study of 26,180 patients ages 2 to 19 seen in five urban pediatric primary care clinics between 2009 and 2016. Data were collected from systematic screening using a computerized clinical decision support system. Multivariable logistic regressions were used to analyze the association between pain reporting and obesity (body mass index), age, sex, race, season, insurance status, clinic site, prior pain reporting, pain reporting method, and exam findings.

RESULTS

Pain was reported by the patient or caregiver in 14.9% of visits. In adjusted models, pain reporting was associated with obesity (Odds Ratio (OR) 1.23, 95% Confidence Intervals (CI) 1.11-1.35) and severe obesity (OR 1.32, CI 1.17-1.49); adolescents (OR 1.47, CI 1.33-1.61); and females (OR 1.21, CI 1.12-1.29). Pain reported at the preceding visit increased odds of pain reporting 2.67 times (CI 2.42-2.95). Abnormal abdominal, extremity, ear, nose, throat, and lymph node exams were associated with pain reporting. Pain reporting increased in minority races within clinics that predominantly saw a concordant race.

CONCLUSIONS

Pain is common in general pediatric encounters, and occurs more frequently in obese children and those who previously reported pain. Pain reporting may be influenced by seasonal variation and clinic factors. Future pediatric pain screening may be guided by associated risk factors to improve identification and targeted healthcare interventions.

Primary care colorectal cancer screening correlates with breast cancer screening: implications for colorectal cancer screening improvement interventions

Objective

National colorectal cancer (CRC) screening rates have plateaued. To optimize interventions targeting those unscreened, a better understanding is needed of how this preventive service fits in with multiple preventive and chronic care needs managed by primary care providers (PCPs). This study examines whether PCP practices of other preventive and chronic care needs correlate with CRC screening.

Methods

We performed a retrospective cohort study of 90 PCPs and 33,137 CRC screening-eligible patients. Five PCP quality metrics (breast cancer screening, cervical cancer screening, HgbA1c and LDL testing, and blood pressure control) were measured. A baseline correlation test was performed between these metrics and PCP CRC screening rates. Multivariable logistic regression with clustering at the clinic-level estimated odds ratios and 95% confidence intervals for these PCP quality metrics, patient and PCP characteristics, and their relationship to CRC screening.

Results

PCP CRC screening rates have a strong correlation with breast cancer screening rates (r = 0.7414, p < 0.001) and a weak correlation with the other quality metrics. In the final adjusted model, the only PCP quality metric that significantly predicted CRC screening was breast cancer screening (OR 1.25; 95% CI 1.11–1.42; p < 0.001).

Conclusions

PCP CRC screening rates are highly concordant with breast cancer screening. CRC screening is weakly concordant with cervical cancer screening and chronic disease management metrics. Efforts targeting PCPs to increase CRC screening rates could be bundled with breast cancer screening improvement interventions to increase their impact and success.

Effect of reminders mailed to general practitioners on colorectal cancer screening adherence: a cluster-randomized trial

Reminders have been used in various settings, but failed to produce convincing evidence of benefits on patient adherence to colorectal cancer (CRC) screening. The aim of this study was to assess the effectiveness of sending general practitioners (GPs) printed reminders about CRC screening. We conducted a cluster-randomized controlled trial involving 144 GPs in the Val-de-Marne district (France), who provided care for any reason to 20 778 patients eligible for CRC screening between June 2010 and November 2011. Data were collected from the main statutory health-insurance programme and local cancer screening agency. GPs were randomly assigned in a 1 : 1 proportion to the intervention or the control group. Every 4 months, intervention-group GPs received a computer-generated printed list of patients who had not performed scheduled faecal occult blood test (FOBT) screening. The primary outcome was patient adherence to FOBT screening or exclusion from CRC screening for medical reasons. The screening adherence rate was 31.2% [95% confidence interval (CI) 30.3-32.1] in the control group and 32.9% (95% CI 32.0-33.8) in the intervention group [crude relative risk, 1.05 (95% CI 1.01-1.09), P<0.01]. This rate was not significantly different between groups by multilevel modelling accounting for clustering and confounding variables [adjusted relative risk, 1.07 (95% CI 0.95-1.20), P=0.27]. Computer-generated printed reminders sent to GPs did not significantly improve patient adherence to organized CRC screening by the FOBT.

Computer-generated reminders delivered on paper to healthcare professionals: effects on professional practice and healthcare outcomes

BACKGROUND

Clinical practice does not always reflect best practice and evidence, partly because of unconscious acts of omission, information overload, or inaccessible information. Reminders may help clinicians overcome these problems by prompting them to recall information that they already know or would be expected to know and by providing information or guidance in a more accessible and relevant format, at a particularly appropriate time. This is an update of a previously published review.

OBJECTIVES

To evaluate the effects of reminders automatically generated through a computerized system (computer-generated) and delivered on paper to healthcare professionals on quality of care (outcomes related to healthcare professionals' practice) and patient outcomes (outcomes related to patients' health condition).

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, six other databases and two trials registers up to 21 September 2016 together with reference checking, citation searching and contact with study authors to identify additional studies.

SELECTION CRITERIA

We included individual- or cluster-randomized and non-randomized trials that evaluated the impact of computer-generated reminders delivered on paper to healthcare professionals, alone (single-component intervention) or in addition to one or more co-interventions (multi-component intervention), compared with usual care or the co-intervention(s) without the reminder component.

DATA COLLECTION AND ANALYSIS

Review authors working in pairs independently screened studies for eligibility and abstracted data. For each study, we extracted the primary outcome when it was defined or calculated the median effect size across all reported outcomes. We then calculated the median improvement and interquartile range (IQR) across included studies using the primary outcome or median outcome as representative outcome. We assessed the certainty of the evidence according to the GRADE approach.

MAIN RESULTS

We identified 35 studies (30 randomized trials and five non-randomized trials) and analyzed 34 studies (40 comparisons). Twenty-nine studies took place in the USA and six studies took place in Canada, France, Israel, and Kenya. All studies except two took place in outpatient care. Reminders were aimed at enhancing compliance with preventive guidelines (e.g. cancer screening tests, vaccination) in half the studies and at enhancing compliance with disease management guidelines for acute or chronic conditions (e.g. annual follow-ups, laboratory tests, medication adjustment, counseling) in the other half.Computer-generated reminders delivered on paper to healthcare professionals, alone or in addition to co-intervention(s), probably improves quality of care slightly compared with usual care or the co-intervention(s) without the reminder component (median improvement 6.8% (IQR: 3.8% to 17.5%); 34 studies (40 comparisons); moderate-certainty evidence).Computer-generated reminders delivered on paper to healthcare professionals alone (single-component intervention) probably improves quality of care compared with usual care (median improvement 11.0% (IQR 5.4% to 20.0%); 27 studies (27 comparisons); moderate-certainty evidence). Adding computer-generated reminders delivered on paper to healthcare professionals to one or more co-interventions (multi-component intervention) probably improves quality of care slightly compared with the co-intervention(s) without the reminder component (median improvement 4.0% (IQR 3.0% to 6.0%); 11 studies (13 comparisons); moderate-certainty evidence).We are uncertain whether reminders, alone or in addition to co-intervention(s), improve patient outcomes as the certainty of the evidence is very low (n = 6 studies (seven comparisons)). None of the included studies reported outcomes related to harms or adverse effects of the intervention.

AUTHORS' CONCLUSIONS

There is moderate-certainty evidence that computer-generated reminders delivered on paper to healthcare professionals probably slightly improves quality of care, in terms of compliance with preventive guidelines and compliance with disease management guidelines. It is uncertain whether reminders improve patient outcomes because the certainty of the evidence is very low. The heterogeneity of the reminder interventions included in this review also suggests that reminders can probably improve quality of care in various settings under various conditions.

Barriers to evidence-based physician decision-making at the point of care: a narrative literature review

We conduct a narrative literature review using four real-world cases of clinical decisions to show how barriers to the use of evidence-based medicine affect physician decision-making at the point of care, and where adjustments could be made in the healthcare system to address these barriers. Our four cases constitute decisions typical of the types physicians make on a regular basis: diagnostic testing, initial treatment and treatment monitoring. To shed light on opportunities to improve patient care while reducing costs, we focus on barriers that could be addressed through changes to policy and/or practice at a particular level of the healthcare system. We conclude by relating our findings to the passage of the Medicare Access and Children's Health Insurance Program Reauthorization Act in April 2015.

Use of a Glucose Algorithm to Direct Diabetes Therapy Improves A1C Outcomes and Defines an Approach to Assess Provider Behavior

Purpose

The purpose of this study was to determine whether an algorithm that recommended individualized changes in therapy would help providers to change therapy appropriately and improve glycemic control in their patients.

Methods

The algorithm recommended specific doses of oral agents and insulin based on a patient's medications and glucose or A1C levels at the time of the visit. The prospective observational study analyzed the effect of the algorithm on treatment decisions and A1C levels in patients with type 2 diabetes.

Results

The study included 1250 patients seen in pairs of initial and follow-up visits during a 7-month baseline and/or a subsequent 7-month algorithm period. The patients had a mean age of 62 years, body mass index of 33 kg/m2, duration of diabetes of 10 years, were 94% African American and 71% female, and had average initial A1C level of 7.7%. When the algorithm was available, providers were 45% more likely to intensify therapy when indicated (P = .005) and increased therapy by a 20% greater amount (P < .001). A1C level at follow-up was 90% more likely to be <7% in the algorithm group, even after adjusting for differences in age, sex, body mass index, race, duration of diabetes and therapy, glucose, and A1C level at the initial visit (P < .001).

Conclusions Use of an algorithm that recommends patient-specific changes in diabetes medications improves both provider behavior and patient A1C levels and should allow quantitative evaluation of provider actions for that provider's patients.

Improved Resident Adherence to AAA Screening Guidelines via an Electronic Reminder

The 2014 United States Preventive Services Task Force systematic review found abdominal aortic aneurysm (AAA) screening decreased related mortality by close to half. Despite the simplicity of screening, research suggests poor adherence to the recommended AAA screening guidelines. Using the quality improvement plan-study-do-act cycle, we retrospectively established poor adherence to AAA screening and poor documentation of smoking history in our resident clinic. An electronic reminder was prospectively implemented into our electronic medical record (EMR) with the goal of improving screening rates. After 1 year, a retrospective chart review was conducted. Comparisons of the pre- and post-electronic reminder intervention data were made using chi-square tests and odds ratios (OR). The purposeful AAA screening rate improved 27.8% during the intervention, 40.3% (95% confidence interval [CI]: 28.6-52.0%) versus 12.5% (95% CI: 3.1-21.9%), p = .002, suggesting patients were more likely to be screened as a result of the electronic reminder, OR = 4.73 (95% CI: 1.77-12.65). This improvement translates to a large effect size, Cohen's d = 0.86 (95% CI: 0.31-1.40). Electronic reminders are a simple EMR addition that can provide evidence-based education while improving adherence rates with preventive health screening measures.

Interventions in Physician-Elderly Patient Interactions

Currently, most research in the area of physician-elderly patient interactions relates to either outcome, context, or interaction styles. There are limited data in the area of intervention studies. The authors recognize five specific areas of interventional research to consider: communication during encounters, characteristics of older patients, physical impairments, physician attributes, and the team approach to health care. Also highlighted are recognition and evaluation of the special needs of elderly patients through geriatric assessment. The authors recognize the need for more intervention studies that attempt to change patient or physician behaviors and the applicability of the classic randomized controlled model of research. Overall, the authors contend that the formation of strong, meaningful relationships between elderly patients and their physicians is best achieved through effective medical communication and care, and thus should be the function of appropriate interventions.

Electronic Health Records: Then, Now, and in the Future

OBJECTIVES

Describe the state of Electronic Health Records (EHRs) in 1992 and their evolution by 2015 and where EHRs are expected to be in 25 years. Further to discuss the expectations for EHRs in 1992 and explore which of them were realized and what events accelerated or disrupted/derailed how EHRs evolved.

METHODS

Literature search based on "Electronic Health Record", "Medical Record", and "Medical Chart" using Medline, Google, Wikipedia Medical, and Cochrane Libraries resulted in an initial review of 2,356 abstracts and other information in papers and books. Additional papers and books were identified through the review of references cited in the initial review.

RESULTS

By 1992, hardware had become more affordable, powerful, and compact and the use of personal computers, local area networks, and the Internet provided faster and easier access to medical information. EHRs were initially developed and used at academic medical facilities but since most have been replaced by large vendor EHRs. While EHR use has increased and clinicians are being prepared to practice in an EHR-mediated world, technical issues have been overshadowed by procedural, professional, social, political, and especially ethical issues as well as the need for compliance with standards and information security. There have been enormous advancements that have taken place, but many of the early expectations for EHRs have not been realized and current EHRs still do not meet the needs of today's rapidly changing healthcare environment.

CONCLUSION

The current use of EHRs initiated by new technology would have been hard to foresee. Current and new EHR technology will help to provide international standards for interoperable applications that use health, social, economic, behavioral, and environmental data to communicate, interpret, and act intelligently upon complex healthcare information to foster precision medicine and a learning health system.

Utilizing an integrated infrastructure for outcomes research: a systematic review

OBJECTIVE

To explore the ability of an integrated health information infrastructure to support outcomes research.

METHODS

A systematic review of articles published from 1983 to 2012 by Regenstrief Institute investigators using data from an integrated electronic health record infrastructure involving multiple provider organisations was performed. Articles were independently assessed and classified by study design, disease and other metadata including bibliometrics.

RESULTS

A total of 190 articles were identified. Diseases included cognitive, (16) cardiovascular, (16) infectious, (15) chronic illness (14) and cancer (12). Publications grew steadily (26 in the first decade vs. 100 in the last) as did the number of investigators (from 15 in 1983 to 62 in 2012). The proportion of articles involving non-Regenstrief authors also expanded from 54% in the first decade to 72% in the last decade. During this period, the infrastructure grew from a single health system into a health information exchange network covering more than 6 million patients. Analysis of journal and article metrics reveals high impact for clinical trials and comparative effectiveness research studies that utilised data available in the integrated infrastructure.

DISCUSSION

Integrated information infrastructures support growth in high quality observational studies and diverse collaboration consistent with the goals for the learning health system. More recent publications demonstrate growing external collaborations facilitated by greater access to the infrastructure and improved opportunities to study broader disease and health outcomes.

CONCLUSIONS

Integrated information infrastructures can stimulate learning from electronic data captured during routine clinical care but require time and collaboration to reach full potential.

Lack of impact of electronic health records on quality of care and outcomes for ischemic stroke

BACKGROUND

Electronic health records (EHRs) may be key tools for improving the quality of health care, particularly for conditions for which guidelines are rapidly evolving and timely care is critical, such as ischemic stroke.

OBJECTIVES

The goal of this study was to determine whether hospitals with EHRs differed on quality or outcome measures for ischemic stroke from those without EHRs.

METHODS

We studied 626,473 patients from 1,236 U.S. hospitals in Get With the Guidelines-Stroke (GWTG-Stroke) from 2007 through 2010, linked with the American Hospital Association annual survey to determine the presence of EHRs. We conducted patient-level logistic regression analyses for each of the outcomes of interest.

RESULTS

A total of 511 hospitals had EHRs by the end of the study period. Hospitals with EHRs were larger and were more often teaching hospitals and stroke centers. After controlling for patient and hospital characteristics, patients admitted to hospitals with EHRs had similar odds of receiving "all-or-none" care (odds ratio [OR]: 1.03; 95% CI: 0.99 to 1.06; p=0.12), of discharge home (OR: 1.02; 95% CI: 0.99 to 1.04; p=0.15), and of in-hospital mortality (OR: 1.01; 95% CI: 0.96 to 1.05; p=0.82). The odds of having a length of stay>4 days was slightly lower at hospitals with EHRs (OR: 0.97; 95% CI: 0.95 to 0.99; p=0.01).

CONCLUSIONS

In our sample of GWTG-Stroke hospitals, EHRs were not associated with higher-quality care or better clinical outcomes for stroke care. Although EHRs may be necessary for an increasingly high-tech, transparent healthcare system, as currently implemented, they do not appear to be sufficient to improve outcomes for this important disease.

Educational interventions for primary healthcare professionals to promote the early diagnosis of cancer: a systematic review

BACKGROUND

Primary healthcare professionals seem to lack knowledge and skills in the area of diagnosing cancer which may lead to more advanced stage at diagnosis, poorer cancer survival figures and increased morbidity. The aim of this study was to examine the evidence of effectiveness of educational interventions for primary healthcare professionals to promote the early diagnosis of cancer.

METHODS

We searched bibliographic databases, the grey literature and reference lists for randomised controlled trials (RCTs) of educational interventions delivered at an individual clinician and practice level.

RESULTS

We found sufficient evidence that interactive education, computerised reminder systems and audit and feedback delivered to clinicians may significantly increase several cancer detection measures in the short term and some evidence that they promote early diagnosis. Whilst educational outreach and local opinion leaders had some effect, formal education alone seemed ineffectual.

CONCLUSION

Certain educational interventions delivered at a clinician as well as at a practice level may promote the early diagnosis of cancer in primary care. There is currently limited evidence for their long-term sustainability and effectiveness.

Effects of facilitated team meetings and learning collaboratives on colorectal cancer screening rates in primary care practices: a cluster randomized trial

PURPOSE

The purpose of this study was to evaluate a primary care practice-based quality improvement (QI) intervention aimed at improving colorectal cancer screening rates.

METHODS

The Supporting Colorectal Cancer Outcomes through Participatory Enhancements (SCOPE) study was a cluster randomized trial of New Jersey primary care practices. On-site facilitation and learning collaboratives were used to engage multiple stakeholders throughout the change process to identify and implement strategies to enhance colorectal cancer screening. Practices were analyzed using quantitative (medical records, surveys) and qualitative data (observations, interviews, and audio recordings) at baseline and a 12-month follow-up.

RESULTS

Comparing intervention and control arms of the 23 participating practices did not yield statistically significant improvements in patients' colorectal cancer screening rates. Qualitative analyses provide insights into practices' QI implementation, including associations between how well leaders fostered team development and the extent to which team members felt psychologically safe. Successful QI implementation did not always translate into improved screening rates.

CONCLUSIONS

Although single-target, incremental QI interventions can be effective, practice transformation requires enhanced organizational learning and change capacities. The SCOPE model of QI may not be an optimal strategy if short-term guideline concordant numerical gains are the goal. Advancing the knowledge base of QI interventions requires future reports to address how and why QI interventions work rather than simply measuring whether they work.

The effect of electronic medical record system sophistication on preventive healthcare for women

OBJECTIVE

To observe the effect of electronic medical record (EMR) system sophistication on preventive women's healthcare.

MATERIALS AND METHODS

Providers in the National Ambulatory Medical Care Survey (NAMCS), 2007-8, were included if they had at least one visit by a woman at least 21 years old. Based on 16 questions from NAMCS, the level of a provider's EMR system sophistication was classified as non-existent, minimal, basic, or fully functional. A two-stage residual-inclusion method was used with ordered probit regression to model the level of EMR system sophistication, and outcome-specific Poisson regressions to predict the number of examinations or tests ordered or performed.

RESULTS

Across the providers, 29.23%, 49.34%, 15.97%, and 5.46% had no, minimal, basic, and fully functional EMR systems, respectively. The breast examination rate was 20.27%, 34.96%, 37.21%, and 44.98% for providers without or with minimal, basic, and fully functional EMR systems, respectively. For breast examinations, pelvic examinations, Pap tests, chlamydia tests, cholesterol tests, mammograms, and bone mineral density (BMD) tests, an EMR system increased the number of these tests and examinations. Furthermore, the level of sophistication increased the number of breast examinations and Pap, chlamydia, cholesterol, and BMD tests.

DISCUSSION

The use of advanced EMR systems in obstetrics and gynecology was limited. Given the positive results of this study, specialists in women's health should consider investing in more sophisticated systems.

CONCLUSIONS

The presence of an EMR system has a positive impact on preventive women's healthcare; the more functions that the system has, the greater the number of examinations and tests given or prescribed.

Computer-generated reminders delivered on paper to healthcare professionals; effects on professional practice and health care outcomes

BACKGROUND

Clinical practice does not always reflect best practice and evidence, partly because of unconscious acts of omission, information overload, or inaccessible information. Reminders may help clinicians overcome these problems by prompting the doctor to recall information that they already know or would be expected to know and by providing information or guidance in a more accessible and relevant format, at a particularly appropriate time.

OBJECTIVES

To evaluate the effects of reminders automatically generated through a computerized system and delivered on paper to healthcare professionals on processes of care (related to healthcare professionals' practice) and outcomes of care (related to patients' health condition).

SEARCH METHODS

For this update the EPOC Trials Search Co-ordinator searched the following databases between June 11-19, 2012: The Cochrane Central Register of Controlled Trials (CENTRAL) and Cochrane Library (Economics, Methods, and Health Technology Assessment sections), Issue 6, 2012; MEDLINE, OVID (1946- ), Daily Update, and In-process; EMBASE, Ovid (1947- ); CINAHL, EbscoHost (1980- ); EPOC Specialised Register, Reference Manager, and INSPEC, Engineering Village. The authors reviewed reference lists of related reviews and studies. 

SELECTION CRITERIA

We included individual or cluster-randomized controlled trials (RCTs) and non-randomized controlled trials (NRCTs) that evaluated the impact of computer-generated reminders delivered on paper to healthcare professionals on processes and/or outcomes of care.

DATA COLLECTION AND ANALYSIS

Review authors working in pairs independently screened studies for eligibility and abstracted data. We contacted authors to obtain important missing information for studies that were published within the last 10 years. For each study, we extracted the primary outcome when it was defined or calculated the median effect size across all reported outcomes. We then calculated the median absolute improvement and interquartile range (IQR) in process adherence across included studies using the primary outcome or median outcome as representative outcome.

MAIN RESULTS

In the 32 included studies, computer-generated reminders delivered on paper to healthcare professionals achieved moderate improvement in professional practices, with a median improvement of processes of care of 7.0% (IQR: 3.9% to 16.4%). Implementing reminders alone improved care by 11.2% (IQR 6.5% to 19.6%) compared with usual care, while implementing reminders in addition to another intervention improved care by 4.0% only (IQR 3.0% to 6.0%) compared with the other intervention. The quality of evidence for these comparisons was rated as moderate according to the GRADE approach. Two reminder features were associated with larger effect sizes: providing space on the reminder for provider to enter a response (median 13.7% versus 4.3% for no response, P value = 0.01) and providing an explanation of the content or advice on the reminder (median 12.0% versus 4.2% for no explanation, P value = 0.02). Median improvement in processes of care also differed according to the behaviour the reminder targeted: for instance, reminders to vaccinate improved processes of care by 13.1% (IQR 12.2% to 20.7%) compared with other targeted behaviours. In the only study that had sufficient power to detect a clinically significant effect on outcomes of care, reminders were not associated with significant improvements.

AUTHORS' CONCLUSIONS

There is moderate quality evidence that computer-generated reminders delivered on paper to healthcare professionals achieve moderate improvement in process of care. Two characteristics emerged as significant predictors of improvement: providing space on the reminder for a response from the clinician and providing an explanation of the reminder's content or advice. The heterogeneity of the reminder interventions included in this review also suggests that reminders can improve care in various settings under various conditions.

Improving delivery of EPSDT well-child care at acute visits in an academic pediatric practice

BACKGROUND AND OBJECTIVE

Many patients with Medicaid do not receive timely, comprehensive well-child care through the Early and Periodic Screening, Diagnosis, and Treatment (EPSDT) program. Missed opportunities for EPSDT well-child check-ups (WCCs) at acute visits contribute to this problem. The authors sought to reduce missed opportunities for WCCs at acute visits for patients overdue for those services.

METHODS

A quality improvement team developed key drivers and used a people-process-technology framework to devise 3 interventions: (1) an electronic indicator based on novel definitions of EPSDT status (up-to-date, due, overdue, no EPSDT), (2) a standardized scheduling process for acute visits based on EPSDT status, and (3) a dedicated nurse practitioner to provide WCCs at acute visits. Data were collected for 1 year after full implementation.

RESULTS

At baseline, 10.3 acute visits per month were converted to WCCs. After intervention, 86.7 acute visits per month were converted. Of 13801 acute visits during the project, 31.2% were not up-to-date. Of those overdue for WCCs, 51.4% (n = 552) were converted to a WCC in addition to the acute visit. Including all patients who were not up-to-date, a total of 1047 acute visits (7.6% of all acute visits) were converted to comprehensive WCCs. Deferring needed WCCs at acute visits resulted in few patients who scheduled or completed future WCC visits.

CONCLUSIONS

Implementation of interventions focused on people-process-technology significantly increased WCCs at acute visits within a feasible and practical model that may be replicated at other academic general pediatrics practices.

Changing clinical practice through patient specific reminders available at the time of the clinical encounter: systematic review and meta-analysis

OBJECTIVE

To synthesise current evidence for the influence on clinical behaviour of patient-specific electronically generated reminders available at the time of the clinical encounter.

DATA SOURCES

PubMed, Cochrane library of systematic reviews; Science Citation Index Expanded; Social Sciences Citation Index; ASSIA; EMBASE; CINAHL; DARE; HMIC were searched for relevant articles.

STUDY ELIGIBILITY CRITERIA, PARTICIPANTS AND INTERVENTIONS

We included controlled trials of reminder interventions if the intervention was: directed at clinician behaviour; available during the clinical encounter; computer generated (including computer generated paper-based reminders); and generated by patient-specific (rather than condition specific or drug specific) data.

STUDY APPRAISAL AND SYNTHESIS METHODS

Systematic review and meta-analysis of controlled trials published since 1970. A random effects model was used to derive a pooled odds ratio for adherence to recommended care or achievement of target outcome. Subgroups were examined based on area of care and study design. Odds ratios were derived for each sub-group. We examined the designs, settings and other features of reminders looking for factors associated with a consistent effect.

RESULTS

Altogether, 42 papers met the inclusion criteria. The studies were of variable quality and some were affected by unit of analysis errors due to a failure to account for clustering. An overall odds ratio of 1.79 [95% confidence interval 1.56, 2.05] in favour of reminders was derived. Heterogeneity was high and factors predicting effect size were difficult to identify.

LIMITATIONS

Methodological diversity added to statistical heterogeneity as an obstacle to meta-analysis. The quality of included studies was variable and in some reports procedural details were lacking.

CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS

The analysis suggests a moderate effect of electronically generated, individually tailored reminders on clinician behaviour during the clinical encounter. Future research should concentrate on identifying the features of reminder interventions most likely to result in the target behaviour.

Secondary uses of electronic health record data: benefits and barriers

In the primary use of health data, patient health information in electronic health records (EHRs) directly informs each individual's care. In secondary use, patient data would be aggregated to improve health care delivery, yet several technological and policy barriers may slow implementation-but may be amenable to intervention.

Users' satisfaction with the primary health care information system in Croatia: a cross-sectional study

Aim

To evaluate the primary health care information system from the general practitioner's (GP) point of view.

Methods

Sixty-seven Croatian GPs were distributed a questionnaire about characteristics of the GP’s office, overall impression of the application, handling of daily routine information, more sophisticated information needs, and data security, and rated their satisfaction with each component from 1 to 5. We also compared two most frequently used applications – application with distantly installed software (DIS) and that with locally installed software (LIS, personal computer-based application).

Results

GPs were most satisfied with the daily procedures and the reminder component of the health information system (rating 4.1). The overall impression ranked second (3.5) and flexibility of applications followed closely (3.4). The most questionable aspect of applications was data security (3.0). LIS system received better overall rate than DIS (4.2 vs 3.2).

Conclusion

Applications received better ratings for daily routine use than for overall impression and ability to get specific information according the GPs’ needs. Poor ratings on the capability of the application, complaints about unreliable links, and doubts about data security point to a need for more user-friendly interfaces, more information on the capability of the application, and a valid certificate of assessment for every application.

Measurement-based care for unipolar depression

This article outlines the role of measurement-based care in the management of antidepressant treatment for patients with unipolar depression. Using measurement-based care, clinicians and researchers have the opportunity to optimize individual treatment and obtain maximum antidepressant treatment response. Measurement-based care breaks down to several simple components: antidepressant dosage, depressive symptom severity, medication tolerability, adherence to treatment, and safety. Quick and easy-to-use, empirically validated assessments are available to monitor these areas of treatment. Utilizing measurement-based care has several steps-screening and antidepressant selection based upon treatment history, followed by assessment-based medication management and ongoing care. Electronic measurement-based care systems have been developed and implemented, further reducing the burden on patients and clinicians. As more treatment providers adopt electronic health care management systems, compatible measurement-based care antidepressant treatment delivery and monitoring systems may become increasingly utilized.

A role for regulatory focus in explaining and combating clinical inertia

RATIONALE, AIMS AND OBJECTIVES

It is well established that clinical inertia generates suboptimal care in patients with chronic diseases, and policies and interventions have yet to satisfactorily address the problem.

METHODS

This paper integrates the relevant literatures on clinical inertia and Regulatory Focus Theory (RFT) from psychology to identify an actionable explanatory mechanism.

RESULTS

We review RFT and show that it provides a mechanism that may explain key provider contributions to clinical inertia. We then identify two general intervention strategies based on RFT: one that changes individual sensitivity to positive/negative outcomes and another that maintains the sensitivity to positive/negative outcome but frames how information is provided to match the sensitivity.

CONCLUSIONS

We conclude that RFT is a plausible explanation to guide the development of policies and interventions for mitigating clinical inertia.

Factors Affecting IT-Based Knowledge Management Strategy in UK Healthcare System

The technological development by the beginning of the 21st century is making it humanly impossible for unaided healthcare professionals to possess all the knowledge needed to deliver medical care with the efficacy and safety made possible by current scientific knowledge. Several healthcare organizations are adopting rigorous methods and technologies for KM as a potential solution to the knowledge predicament. However, awareness and understanding of such methods are not widespread with critics claiming that these technologies are not designed to be compatible with others neither are they interoperable.

This paper describes an effort by the NHS for individuals, organizations and partners (commercial companies supplying services to the NHS) to demonstrate their belief in the importance of improving KM in medicine and show that this can be best achieved through collaboration and consensus. It looks at National Knowledge Service, set up to provide a range of services, through one or more open-access web sites.

There is an asymmetry in most of the discussion of the field. KM, in this paper, is primarily discussed from the point of view of the user of medical knowledge. The motivation is seen to be the enhancement capabilities, and the utilization of knowledge to increase healthcare effectiveness.

The role of physician reminders in faecal occult blood testing for colorectal cancer screening

BACKGROUND

Colorectal cancer screening in the form of faecal occult blood (FOB) testing can significantly reduce the burden of this disease and has been used as early as the 1970s. Effective involvement of GPs along with reminding physicians prior to seeing a patient may improve uptake.

OBJECTIVE

This article is a systematic review of published literature examining the uptake of FOB testing after physician reminders as part of the colorectal cancer screening process.

METHODS

Electronic databases were searched from January 1975 to October 2010. All studies comparing physician reminders (Rem) with controls (NRem) were identified. A meta-analysis was performed to obtain a summary outcome.

RESULTS

Five comparative studies involving 25 287 patients were analyzed. There were 12 641 patients were in the Rem and 12 646 in the NRem group. All five studies obtained a higher percentage uptake when physician reminders were given. However, in only two of the studies were the percentage uptake significantly higher. There was significant heterogeneity among trials (I2 = 95%). The combined increase in FOB test uptake was not statistically significant (random effects model: risk difference = 6.6%, 95% CI: -2-14.7%; z = 1.59, P = 0.112).

CONCLUSION

Reminding physicians about those patients due for FOB testing may not improve the effectiveness of a colorectal cancer screening programme. Further studies are required and should focus on areas where there is a lower baseline uptake and areas with high levels of deprivation.

Interventions targeted at women to encourage the uptake of cervical screening

BACKGROUND

World-wide, cervical cancer is the second most common cancer in women. Increasing the uptake of screening, alongside increasing informed choice is of great importance in controlling this disease through prevention and early detection.

OBJECTIVES

To assess the effectiveness of interventions aimed at women, to increase the uptake, including informed uptake, of cervical cancer screening.

SEARCH STRATEGY

We searched the Cochrane Gynaecological Cancer Group Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL), Issue 1, 2009. MEDLINE, EMBASE and LILACS databases up to March 2009. We also searched registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field.

SELECTION CRITERIA

Randomised controlled trials (RCTs) of interventions to increase uptake/informed uptake of cervical cancer screening.

DATA COLLECTION AND ANALYSIS

Two review authors independently abstracted data and assessed risk of bias. Where possible the data were synthesised in a meta-analysis.

MAIN RESULTS

Thirty-eight trials met our inclusion criteria. These trials assessed the effectiveness of invitational and educational interventions, counselling, risk factor assessment and procedural interventions. Heterogeneity between trials limited statistical pooling of data. Overall, however, invitations appear to be effective methods of increasing uptake. In addition, there is limited evidence to support the use of educational materials. Secondary outcomes including cost data were incompletely documented so evidence was limited. Most trials were at moderate risk of bias. Informed uptake of cervical screening was not reported in any trials.

AUTHORS' CONCLUSIONS

There is evidence to support the use of invitation letters to increase the uptake of cervical screening. There is limited evidence to support educational interventions but it is unclear what format is most effective. The majority of the studies are from developed countries and so the relevance to developing countries is unclear.

Randomized clinical trial of a customized electronic alert requiring an affirmative response compared to a control group receiving a commercial passive CPOE alert: NSAID--warfarin co-prescribing as a test case

BACKGROUND

Studies that have looked at the effectiveness of computerized decision support systems to prevent drug-drug interactions have reported modest results because of low response by the providers to the automated alerts.

OBJECTIVE

To evaluate, within an inpatient computerized physician order entry (CPOE) system, the incremental effectiveness of an alert that required a response from the provider, intended as a stronger intervention to prevent concurrent orders of warfarin and non-steroidal anti-inflammatory drugs (NSAIDs).

DESIGN

Randomized clinical trial of 1963 clinicians assigned to either an intervention group receiving a customized electronic alert requiring affirmative response or a control group receiving a commercially available passive alert as part of the CPOE. The study duration was 2 August 2006 to 15 December 2007.

MEASUREMENTS

Alert adherence was compared between study groups.

RESULTS

The proportion of desired ordering responses (ie, not reordering the alert-triggering drug after firing) was lower in the intervention group (114/464 (25%) customized alerts issued) than in the control group (154/560 (28%) passive alerts firing). The adjusted OR of inappropriate ordering was 1.22 (95% CI 0.69 to 2.16).

CONCLUSION

A customized CPOE alert that required a provider response had no effect in reducing concomitant prescribing of NSAIDs and warfarin beyond that of the commercially available passive alert received by the control group. New CPOE alerts cannot be assumed to be effective in improving prescribing, and need evaluation.

Improving colonoscopy referral rates through computer-supported, primary care practice redesign

This quality improvement project was designed to improve rates of referral for colonoscopy screening in the Utah Health Research Network, University of Utah Community Clinics. This study was conducted between October 2004 and June 2007 with the main intervention being a clinic workflow modification using computerized screening reminders embedded in the electronic medical record (EMR). The intervention led to sustained improvement, largely driven by the performance of two network clinics. This study demonstrates that a robust EMR, with decision prompts, accompanied by clinic workflow changes and feedback to providers, can lead to sustained change in the rates of colonoscopy referral.

Early telephone intervention for psychiatric outpatients starting antidepressant treatment

BACKGROUND

The article addresses the hypothesis that early telephone intervention for psychiatric outpatients starting antidepressant treatment would increase compliance with pharmacological treatment and retention time in the study, and thus allow for a more favourable clinical outcome.

METHODS

The study focuses on 131 depressed outpatients who participated in a study aiming to obtain full remission. Patients who benefited from three early structured telephone interventions (n=81) were compared with participants who benefited from the usual care (n=50) with no clinical contact before the first clinical assessment at 2 weeks.

RESULTS

The intervention proved to have no significant effect on treatment adherence, attrition rate, exclusion rate for adverse events or improvement of depression severity. It was nevertheless associated with increased retention time in the present study.

CONCLUSIONS

These results suggest that motivational phone calls may reinforce adhesion in psychiatric patients and provide early opportunities to adapt treatment to individual needs.

CLINICAL IMPLICATION

These results suggest that motivational phone calls may reinforce adhesion in psychiatric patients and provide early opportunities to adapt treatment to individual needs.

Documentation of preventive screening interventions by general practitioners: a retrospective chart audit

Background

Screening and early diagnosis has been shown to reduce the morbidity and mortality associated with certain conditions such as cervical cancer. The role of general practitioners in promoting primary prevention of diseases is particularly important given that they have frequent contact with a large proportion of the population. This study assessed the extent to which general practitioners documented recommended preventive screening interventions among eligible patients.

Methods

We used a retrospective chart audit to assess patient visits to primary care clinics in Calgary, Canada from 2002-2004. We included fee for service physicians who practiced ≥ 2 days per week at their current location and excluded those whose primary practice was at walk-in clinics, community health centers, hospitals or emergency rooms. We included charts of patients who during the study period were age 35 years or older and had at least 2 visits to a clinic. We randomly selected and reviewed charts (N = 600) from 12 primary care clinics and abstracted information on 6 conditions recommended for preventive screening. Opportunities for preventive screening were determined based on recommendations of the Canadian Task Force on Preventive Health Care, the American College of Physicians, and the Canadian Cancer Society. Our main outcome measures included cancer screening (mammography and pap smears), immunization (influenza and pneumococcal), and risk factor assessment (cholesterol measurement and smoking cessation consultation).

Results

Patient visits to GP clinics present opportunities for preventive screening. However, we found that documentation of interventions was low, ranging from 40.3% (cholesterol measurement) to 0.9% (pneumococcal vaccination) within 1 year, and from 67.4% to 1.8% within the prior 3 years.

Conclusions

Documentation of preventive screening interventions by general practitioners was relatively low compared to the number of patients eligible for preventive screening. Some physicians opt to screen for PSA and DRE which is not recommended by the Canadian Task Force on Preventive HealthCare.

Intervention to increase recommendation and delivery of screening for breast, cervical, and colorectal cancers by healthcare providers a systematic review of provider reminders

Most major medical organizations recommend routine screening for breast, cervical, and colorectal cancers. Screening can lead to early detection of these cancers, resulting in reduced mortality. Yet, not all people who should be screened are screened regularly or, in some cases, ever. This report presents results of systematic reviews of effectiveness, applicability, economic efficiency, barriers to implementation, and other harms or benefits of provider reminder/recall interventions to increase screening for breast, cervical, and colorectal cancers. These interventions involve using systems to inform healthcare providers when individual clients are due (reminder) or overdue (recall) for specific cancer screening tests. Evidence in this review of studies published from 1986 through 2004 indicates that reminder/recall systems can effectively increase screening with mammography, Pap, fecal occult blood tests, and flexible sigmoidoscopy. Additional research is needed to determine if provider reminder/recall systems are effective in increasing colorectal cancer screening by colonoscopy. Specific areas for further research are also suggested.

Improving preventive foot care for diabetic patients participating in group education

BACKGROUND

Diabetic foot care has yet to be enhanced in a universal health-care system in which specialized podiatric medical services are unavailable. This baseline assessment surveyed diabetic patients attending group education to improve current foot-care practices.

METHODS

Of 302 diabetic patients receiving usual outpatient care, 155 received group patient education on general diabetes-related information, which included foot care and an annual checkup by a diabetes association during the previous 2 years, and 147 did not. Patient foot-care behaviors, physician practice patterns, and patient self-perceived foot risk as cross-checked with the neurologic and vascular assessments were investigated by conducting retrospective medical record reviews and structured interviews.

RESULTS

More than half of the patients in both groups reported inappropriate self-care behaviors (eg, walking barefoot and heating or soaking their feet). The percentages of patients receiving documented examinations and referrals for foot problems were low in both groups and were not significantly different. Among at-risk patients, 56% of the diabetes association group but only 30% of the non-diabetes association group perceived themselves to be at risk for future foot problems (P<.01).

CONCLUSIONS

Many diabetic patients were not offered adequate foot-specific information during group lectures, even those with high-risk foot problems. To improve this, combining caregiver and patient education in foot-care practices is important, and systems of networked multidisciplinary professionals are believed to be needed, particularly in delivering customized interventions to at-risk patients based on the initial evaluation.

Home-based blood pressure interventions for blacks

Efforts to increase blood pressure (BP) control rates in blacks, a traditionally underserved high-risk population must address both provider practice and patient adherence issues. The home-based BP Intervention for blacks study is a 3-arm randomized controlled trial designed to test 2 strategies to improve hypertension management and outcomes in a decentralized service setting serving a vulnerable and complex home care population. The primary study outcomes are systolic BP, diastolic BP, and BP control; secondary outcomes are nurse adherence to hypertension management recommendations and patient adherence to medication, healthy diet, and other self-management strategies. Nurses (n=312) in a nonprofit Medicare-certified home health agency are randomized along with their eligible hypertensive patients (n=845). The 2 interventions being tested are (1) a "basic" intervention delivering key evidence-based reminders to home care nurses and patients while the patient is receiving traditional postacute home health care; and (2) an "augmented" intervention that includes that same as the basic intervention, plus transition to an ongoing Hypertension Home Support Program that extends support for 12 months. Outcomes are measured at 3 and 12 months after baseline interview. The interventions will be assessed relative to usual care and to each other. Systems change to improve BP management and outcomes in home health will not easily occur without new intervention models and rigorous evaluation of their impact. Results from this trial will provide important information on potential strategies to improve BP control in a low-income chronically ill patient population.

A national clinical decision support infrastructure to enable the widespread and consistent practice of genomic and personalized medicine

BACKGROUND

In recent years, the completion of the Human Genome Project and other rapid advances in genomics have led to increasing anticipation of an era of genomic and personalized medicine, in which an individual's health is optimized through the use of all available patient data, including data on the individual's genome and its downstream products. Genomic and personalized medicine could transform healthcare systems and catalyze significant reductions in morbidity, mortality, and overall healthcare costs.

DISCUSSION

Critical to the achievement of more efficient and effective healthcare enabled by genomics is the establishment of a robust, nationwide clinical decision support infrastructure that assists clinicians in their use of genomic assays to guide disease prevention, diagnosis, and therapy. Requisite components of this infrastructure include the standardized representation of genomic and non-genomic patient data across health information systems; centrally managed repositories of computer-processable medical knowledge; and standardized approaches for applying these knowledge resources against patient data to generate and deliver patient-specific care recommendations. Here, we provide recommendations for establishing a national decision support infrastructure for genomic and personalized medicine that fulfills these needs, leverages existing resources, and is aligned with the Roadmap for National Action on Clinical Decision Support commissioned by the U.S. Office of the National Coordinator for Health Information Technology. Critical to the establishment of this infrastructure will be strong leadership and substantial funding from the federal government.

SUMMARY

A national clinical decision support infrastructure will be required for reaping the full benefits of genomic and personalized medicine. Essential components of this infrastructure include standards for data representation; centrally managed knowledge repositories; and standardized approaches for leveraging these knowledge repositories to generate patient-specific care recommendations at the point of care.

Patient and physician reminders to promote colorectal cancer screening: a randomized controlled trial

BACKGROUND

Screening reduces colorectal cancer mortality, but effective screening tests remain underused. Systematic reminders to patients and physicians could increase screening rates

METHODS

We conducted a randomized controlled trial of patient and physician reminders in 11 ambulatory health care centers. Participants included 21 860 patients aged 50 to 80 years who were overdue for colorectal cancer screening and 110 primary care physicians. Patients were randomly assigned to receive mailings containing an educational pamphlet, fecal occult blood test kit, and instructions for direct scheduling of flexible sigmoidoscopy or colonoscopy. Physicians were randomly assigned to receive electronic reminders during office visits with patients overdue for screening. The primary outcome was receipt of fecal occult blood testing, flexible sigmoidoscopy, or colonoscopy over 15 months, and the secondary outcome was detection of colorectal adenomas.

RESULTS

Screening rates were higher for patients who received mailings compared with those who did not (44.0% vs 38.1%; P < .001). The effect increased with age: +3.7% for ages 50 to 59 years; +7.3% for ages 60 to 69 years; and +10.1% for ages 70 to 80 years (P = .01 for trend). Screening rates were similar among patients of physicians receiving electronic reminders and the control group (41.9% vs 40.2%; P = .47). However, electronic reminders tended to increase screening rates among patients with 3 or more primary care visits (59.5% vs 52.7%; P = .07). Detection of adenomas tended to increase with patient mailings (5.7% vs 5.2%; P = .10) and physician reminders (6.0% vs 4.9%; P = .09).

CONCLUSIONS

Mailed reminders to patients are an effective tool to promote colorectal cancer screening, and electronic reminders to physicians may increase screening among adults who have more frequent primary care visits.

Electronic result viewing and quality of care in small group practices

BACKGROUND

There is a paucity of data on the effectiveness of commercially available electronic systems for improving health care in office practices, where the majority of health care is delivered. In particular, the effect of electronic laboratory result viewing on quality of care, including preventive care, chronic disease management, and patient satisfaction, is unclear.

OBJECTIVE

To determine whether electronic laboratory result viewing is associated with higher ambulatory care quality.

METHODS

We conducted a cross-sectional study of primary care physicians (PCPs) in the Taconic IPA in New York, all of whom have the opportunity to use a free-standing electronic portal for laboratory result viewing. We analyzed 15 quality measures, reflecting preventive care, chronic disease management, and patient satisfaction, which were collected in 2005. Using generalized estimating equations, we determined associations between portal usage and quality, adjusting for adoption of electronic health records and 10 other physician characteristics, including case mix.

MAIN RESULTS

One-third of physicians (54/168, 32%) used the portal at least once over a 6-month period. Use of the portal was associated with higher quality overall (adjusted odds ratio [OR] 1.25; 95% confidence interval [CI] 1.003, 1.57). In stratified analyses, portal usage was associated with higher quality on those performance measures expected to be impacted by result viewing (adjusted OR 1.34; 95% CI 1.00, 1.81; p = 0.05), but not associated with quality for measures not expected to be impacted by result viewing (adjusted OR 1.03; 95% CI 0.72, 1.48; p = 0.85).

CONCLUSION

Electronic laboratory result viewing was independently associated with higher ambulatory care quality. Longitudinal studies are needed to confirm this association.

Prompting clinicians about preventive care measures: a systematic review of randomized controlled trials

Preventive care measures remain underutilized despite recommendations to increase their use. The objective of this review was to examine the characteristics, types, and effects of paper- and computer-based interventions for preventive care measures. The study provides an update to a previous systematic review. We included randomized controlled trials that implemented a physician reminder and measured the effects on the frequency of providing preventive care. Of the 1,535 articles identified, 28 met inclusion criteria and were combined with the 33 studies from the previous review. The studies involved 264 preventive care interventions, 4,638 clinicians and 144,605 patients. Implementation strategies included combined paper-based with computer generated reminders in 34 studies (56%), paper-based reminders in 19 studies (31%), and fully computerized reminders in 8 studies (13%). The average increase for the three strategies in delivering preventive care measures ranged between 12% and 14%. Cardiac care and smoking cessation reminders were most effective. Computer-generated prompts were the most commonly implemented reminders. Clinician reminders are a successful approach for increasing the rates of delivering preventive care; however, their effectiveness remains modest. Despite increased implementation of electronic health records, randomized controlled trials evaluating computerized reminder systems are infrequent.

WITHDRAWN: Mefloquine for preventing malaria in non-immune adult travellers

BACKGROUND

Mefloquine is commonly prescribed to prevent malaria in travellers, and has replaced other drugs because Plasmodium falciparum is commonly resistant to them. However, mefloquine may be associated with neuropsychiatric harmful effects.

OBJECTIVES

To assess the effects of mefloquine in adult travellers compared to other regimens in relation to episodes of malaria, withdrawal from prophylaxis, and adverse events.

SEARCH STRATEGY

We searched the Cochrane Infectious Diseases Group specialized trials register (September 2002), The Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 3, 2002), MEDLINE (1966 to September 2002), EMBASE (1980 to September 2002), LILACS (September 2002), Science Citation Index (1981 to September 2002), and bibliographies in retrieved papers and standard textbooks. We contacted researchers in the subject of malaria chemoprophylaxis, and pharmaceutical companies.

SELECTION CRITERIA

Randomised trials comparing mefloquine with other standard prophylaxis or placebo in non-immune adult travellers, and in non-travelling volunteers. For adverse events, any published case reports were collected.

DATA COLLECTION AND ANALYSIS

We independently assessed trial quality and extracted data. Adverse events from observational studies were categorised by the study type. We also contacted study authors.

MAIN RESULTS

We included 10 trials involving 2750 non-immune adult participants. Five of these were field trials, and of these all were in mainly male soldiers. One trial comparing mefloquine with placebo showed mefloquine prevented malaria episodes in an area of drug resistance (Peto odds ratio 0.04, 95% confidence interval 0.02 to 0.08). Withdrawals in the mefloquine group were consistently higher in four placebo controlled trials (odds ratio 3.56, 95% confidence interval 1.67 to 7.60). In five trials comparing mefloquine with other chemoprophylaxis, no difference in tolerability was detected. We found 516 published case reports of mefloquine adverse effects. 63 per cent of these published reports involved tourists and business travellers. There were four fatalities attributed to mefloquine.

AUTHORS' CONCLUSIONS

Mefloquine prevents malaria, but has adverse effects that limit its acceptability . There is evidence from non-randomised studies that mefloquine has potentially harmful effects in tourists and business travellers, and its use needs to be carefully balanced against this. Trials of comparative effects of antimalarial prophylaxis should include episodes of malaria and withdrawal from prophylaxis as outcomes.
