Association between primary care practice characteristics and emergency department use in a medicaid managed care organization

Comparing Emergency Department Use Among Medicaid and Commercial Patients Using All-Payer All-Claims Data

The high rate of emergency department (ED) use by Medicaid patients is not fully understood. The objective of this paper is (1) to provide context for ED service use by comparing Medicaid and commercial patients' differences across ED and non-ED health service use, and (2) to assess the extent to which Medicaid-commercial differences in ED use can be explained by observable factors in administrative data. Statistical decomposition methods were applied to ED, mental health, and inpatient care using 2011-2013 Medicaid and commercial insurance claims from the Oregon All Payer All Claims database. Demographics, comorbidities, health services use, and neighborhood characteristics accounted for 44% of the Medicaid-commercial difference in ED use, compared to 83% for mental health care and 75% for inpatient care. This suggests that relative to mental health and inpatient care, a large portion of ED use cannot be explained by administrative data. Models that further accounted for patient access to different primary care physicians explained an additional 8% of the Medicaid-commercial difference in ED use, suggesting that the quality of primary care may influence ED use. The remaining unexplained difference suggests that appropriately reducing ED use remains a credible target for policy makers, although success may require knowledge about patients' perceptions and behaviors as well as social determinants of health.

Does the extension of primary care practice opening hours reduce the use of emergency services?

Overcrowding in emergency departments generates potential inefficiencies. Using regional administrative data, we investigate the impact that an increase in the accessibility of primary care has on emergency visits in Italy. We consider two measures of avoidable emergency visits recorded at list level for each General Practitioner. We test whether extending practices' opening hours to up to 12 hours/day reduces the inappropriate utilization of emergency services. Since subscribing to the extension program is voluntary, we account for the potential endogeneity of participation in a count model for emergency admissions in two ways: first, we use a two-stage residual inclusion approach. Then we exploit panel methods on data covering a three-year period, thus accounting directly for individual heterogeneity. Our results show that increasing primary care accessibility acts as a restraint on the inappropriate use of emergency departments. The estimated effect is in the range of a 10-15% reduction in inappropriate admissions.

Federally Qualified Health Center Access and Emergency Department Use Among Children

OBJECTIVE

To determine whether increasing access to federally qualified health centers (FQHCs) in California was associated with decreased rates of emergency department (ED) use by children without insurance or insured by Medicaid.

METHODS

We combined several data sets to longitudinally analyze 58 California counties between 2005 and 2013. We defined access to FQHCs by county using 2 measures: FQHC sites per 100 square miles between 2005 and 2012 and percentage of Medicaid-insured and uninsured children served by FQHCs from 2008 to 2013. Our outcome was rates of ED use by uninsured or Medicaid-insured children ages 0 to 18 years. To determine the effect of changes in FQHC access on the outcome within a county over time, we used negative binomial models with county fixed effects and controls for preselected time-varying county characteristics and secular trends.

RESULTS

Increased geographic density of FQHC sites was associated with ≤18% lower rates of ED visits among Medicaid-insured children and ≤40% lower ED utilization among uninsured children (P = .05 and P < .01, respectively). However, the percentage of Medicaid-insured and uninsured children seen at FQHCs was not associated with any significant change in ED visit rates among Medicaid-insured or uninsured children.

CONCLUSIONS

Whereas increased geographic FQHC access was associated with lower rates of ED use by uninsured children, all other measures of FQHC access were not associated with statistically significant changes in pediatric ED use. These results provide community-level evidence that expanding FQHCs may have a limited impact on pediatric ED use, suggesting the need to explore additional factors driving ED utilization.

Can increased primary care access reduce demand for emergency care? Evidence from England's 7-day GP opening

Restricted access to primary care can lead to avoidable, excessive use of expensive emergency care. Since 2013, partly to alleviate overcrowding at the Accident & Emergency (A&E) units of hospitals, the UK has been piloting 7-day opening of General Practitioner (GP) practices to improve primary care access for patients. We evaluate the impact of these pilots on patient attendances at A&E. We estimate that 7-day GP opening has reduced A&E attendances by patients of pilot practices by 9.9% with most of the impact on weekends which see A&E attendances fall by 17.9%. The effect is non-monotonic in case severity with most of the fall occurring in cases of moderate severity. An additional finding is that there is also a 9.9% fall in weekend hospital admissions (from A&E) which is entirely driven by a fall in admissions of elderly patients. The impact on A&E attendances appears to be bigger among wealthier patients. We present evidence in support of a causal interpretation of our results and discuss policy implications.

Validation of an algorithm to determine the primary care treatability of emergency department visits

OBJECTIVES

We propose a new claims-computable measure of the primary care treatability of emergency department (ED) visits and validate it using a nationally representative sample of Medicare data.

STUDY DESIGN AND SETTING

This is a validation study using 2011-2012 Medicare claims data for a nationally representative 5% sample of fee-for-service beneficiaries to compare the new measure's performance to the Ballard variant of the Billings algorithm in predicting hospitalisation and death following an ED visit.

OUTCOMES

Hospitalisation within 1 day or 1 week of an ED visit; death within 1 week or 1 month of an ED visit.

RESULTS

The Minnesota algorithm is a strong predictor of hospitalisations and deaths, with performance similar to or better than the most commonly used existing algorithm to assess the severity of ED visits. The Billings/Ballard algorithm is a better predictor of death within 1 week of an ED visit; this finding is entirely driven by a small number of ED visits where patients appear to have been dead on arrival.

CONCLUSIONS

The procedure-based approach of the Minnesota algorithm allows researchers to use the clinical judgement of the ED physician, who saw the patient to determine the likely severity of each visit. The Minnesota algorithm may thus provide a useful tool for investigating ED use in Medicare beneficiaries.

Factors associated with choosing the emergency department as the primary access point to health care: a Canadian population cross-sectional study

Objective

Approximately 4.3 million Canadians are without a primary care physician, of which 13% choose the emergency department (ED) as their regular access point to health care. We sought to identify factors associated with preferential ED use over other health services. We hypothesized that socioeconomic barriers (i.e., employment, health status, education) to primary care would also prevent access to ED alternatives.

Methods

Data from the Canadian Community Health Survey, 2007 to 2008, were analysed (N=134,073; response rate 93.5%). Our study population comprised 14,091 individuals identified without a primary care physician. Socioeconomic variables included employment, health, and education. Covariates included chronic health conditions, immigrant status, gender, age, and mental health. Prevalence estimates and 95% confidence intervals (CIs) for each variable were calculated. Weighted logistic regression models were constructed to evaluate the importance of individual risk factors and their interactions after adjustment for relevant covariates.

Results

The sample comprised 57.2% males from across Canada. Employment (OR 0.73 [95% CI: 0.59-0.90]), good health (OR 0.73 [95% CI 0.57-0.88]), and post-secondary education (OR 0.68 [95% CI 0.53-0.88]) reduced respondents use of the ED. The reduced odds of ED use were independent of chronic conditions, mental health, gender, poor mobility, province, and age.

Conclusions

Low socioeconomic status dictates preferential ED use in those without a primary care physician. Specific policy and system development targeting this at-risk population are indicated to alter ED use patterns in this population.

Determinates of Throughput Times in the Emergency Department

This article studies factors that affect throughput times in a level 1 inner city emergency department (ED) in Chicago, USA. Previous research has shown increased throughput times are related to non-urgent patient use of the ED and lack of coordination of auxiliary hospital departments. Knowledge of these factors will allow for an improvement in patient flow and a reduction in wait times. This is a retrospective study of all factors that contribute to throughput times. Data was collected on a monthly basis for a four-year period that included presenting illness, triage level, wait times, time taken for laboratory results, radiology, bed availability, admitted or sent home, Fast Track availability, age, gender and race. The results show that factors affecting throughput are influenced by numerous determinants often beyond the ED itself. The two most influential are: the numbers of presenting illnesses that require in-patient beds, and the ability of the hospital's auxiliary departments, such as the lab, to meet the needs of the ED in a timely fashion. Based on these findings, the way to reduce throughput times is to focus on auxiliary hospital systems, such as laboratory, psychiatry and medicine, which support the ED.

Emergency Department Utilization Report to Decrease Visits by Pediatric Gastroenterology Patients

BACKGROUND AND OBJECTIVES

Emergency department (ED) utilization is a major driver of health care costs. Specialist physicians have an important role in addressing ED utilization, especially at highly specialized, academic medical centers. We sought to investigate whether reporting of ED utilization to specialist physicians can decrease ED visits.

METHODS

This study analyzed an intervention to reduce ED utilization among ED patients who were followed by pediatric gastroenterologists. In May 2013, each pediatric gastroenterologist began receiving reports with rates of ED use by their patients. The reports generated discussion that resulted in a cultural and process change in which patients with urgent gastrointestinal (GI)-related complaints were preferentially seen in the office. Using control charts, we examined GI-related and all-diagnoses ED use over a 2-year period.

RESULTS

The rate of GI-related ED visits decreased by 60% after the intervention, from 4.89 to 1.95 per 1000 office visits (P < .001). Similarly, rates of GI-related ED visits during office hours decreased by 59% from 2.19 to 0.89 per 1000 (P < .001). Rates of all-diagnoses ED visits did not change.

CONCLUSIONS

Physician-level reporting of ED utilization to pediatric gastroenterologists was associated with physician engagement and a cultural and process change to preferentially treat patients with urgent issues in the office.

Personal Characteristics and Experience of Primary Care Predicting Frequent Use of Emergency Department: A Prospective Cohort Study

OBJECTIVE

A small number of patients frequently using the emergency department (ED) account for a disproportionate amount of the total ED workload and are considered using this service inappropriately. The aim of this study was to identify prospectively personal characteristics and experience of organizational and relational dimensions of primary care that predict frequent use of ED.

METHODS

This study was conducted among parallel cohorts of the general population and primary care patients (N = 1,769). The measures were at baseline (T1), 12 (T2) and 24 months (T3): self-administered questionnaire on current health, health behaviours and primary care experience in the previous year. Use of medical services was confirmed using administrative databases. Mixed effect logistic regression modeling identified characteristics predicting frequent ED utilization.

RESULTS

A higher likelihood of frequent ED utilization was predicted by lower socioeconomic status, higher disease burden, lower perceived organizational accessibility, higher number of reported healthcare coordination problems and not having a complete annual check-up, above and beyond adjustment for all independent variables.

CONCLUSIONS

Personal characteristics such as low socioeconomic status and high disease burden as well as experience of organizational dimensions of primary care such as low accessibility, high healthcare coordination problems and low comprehensiveness of care are prospectively associated with frequent ED utilization. Interventions developed to prevent inappropriate ED visits, such as case management for example, should tailor low socioeconomic status and patients with high disease burden and should aim to improve experience of primary care regarding accessibility, coordination and comprehensiveness.

Population Health: A New Paradigm for Medicine

Healthcare delivery system reform has become a dominant topic of conversation throughout the United States. Driven in part by ever-higher national expenditures on health, an increasing number of payers and provider organizations are working to reduce the costs and improve the quality of healthcare. In this article, we demystify the term "Population Health," review some of the larger payer initiatives currently in effect and discuss specific provider group efforts to improve the quality and cost of healthcare for patients.

Targeting frequent users of emergency departments: Prominent risk factors and policy implications

This study investigates the characteristics of frequent users of accident and emergency departments (AEDs) and recommends alternative medical services for such patients. Prominent demographic and clinical risk factors for individuals accessing seven AEDs located in the metropolitan area of Genoa, Italy are identified and analysed. A truncated count data model is implemented to establish the determinants of access, while a multinomial logistic regression is used to highlight potential differences among different user categories. According to previous studies, empirical findings suggest that despite the relevance of demographic drivers, vulnerability conditions (e.g. abuse of alcohol and drugs, chronic conditions, and psychological distress) are the main reasons behind frequent AED use; the analysis seems to confirm an association between AED frequent use and lower level of urgency. Since frequent and highly frequent users are found responsible for disproportionate resource absorption with respect to total amount of AED costs (they represent roughly 10% of the total number of patients, but contribute to more than 19% of the total annual AED cost), policies aiming to reduce frequent use of AEDs could bring significant savings in economic resources. Thus, efficient actions could be oriented toward extending primary care services outside AED and toward instituting local aid services specifically addressed to people under the influence of substances or in conditions of mental distress.

Demographic factors influencing nonurgent emergency department utilization among a Medicaid population

To use administrative medical encounter data to examine nonurgent emergency department (ED) utilization as it relates to member characteristics (i.e., age, gender, race/ethnicity, urbanicity and federal poverty level (FPL)). This 1 year cross-sectional study used medical claims from a managed care organization for Medicaid members enrolled from October 1, 2010 - September 30, 2011. ED encounters occurring during the study period were classified as either urgent or nonurgent using ICD-9 diagnosis codes obtained from medical claims. Examples of urgent diagnoses include head traumas, burns, allergic reactions, poisonings, preterm labor or maternal/fetal distress. A total of 187,263 members aged 2 to 65 years were retained for study. A zero-inflated Poisson regression model examined the influence of member-level characteristics on nonurgent ED utilization, while simultaneously adjusting for all factors. Females were 41 % more likely to have a nonurgent ED visit (p ≤ 0.0001). Members ages 50-65 were least likely to have a nonurgent ED visit (p ≤ 0.0001). White members had higher odds of having at least one nonurgent ED visit (p ≤ 0.0002). Rural members were 7.7 % less likely to have a nonurgent ED visit. Members in the 400 % + FPL category were less likely to seek nonurgent care from an ED (p ≤ 0.0001). A nonurgent ED visit occurs when care is sought at an ED that could have been handled in a primary care setting. Approximately 30-50 % of all ED visits in the United States are considered nonurgent. This study supports the need to determine factors associated with misuse of ED services for nonurgent care. Demographic factors significantly impacting nonurgent ED utilization include gender, age, race/ethnicity, urbanicity and percent of the FPL. Results may be useful in ED utilization management efforts.

Accessible and continuous primary care may help reduce rates of emergency department use. An international survey in 34 countries

BACKGROUND

Part of the visits to emergency departments (EDs) is related to complaints that may well be treated in primary care.

OBJECTIVES

(i) To investigate how the likelihood of attending an ED is related to accessibility and continuity of primary care. (ii) To investigate the reasons for patients to visit EDs in different countries.

METHODS

Data were collected within the EU Seventh Framework project Quality and Costs in Primary Care (QUALICOPC) in 31 European countries, Australia, New Zealand and Canada. The data were collected between 2011 and 2013 and contain survey data from 60991 patients and 7005 GPs, within 7005 general practices.

OUTCOME MEASURE

whether the patient visited the ED in the previous year (yes/no). Multilevel logistic regression analyses were carried out to analyse the data.

RESULTS

Some 29.4% had visited the ED in the past year. Between countries, the percentages varied between 18% and 40%. ED visits show a significant and negative relation with better accessibility of primary care. Patients with a regular doctor who knows them personally were less likely to attend EDs. Only one-third of all patients who visited an ED indicated that the main reason for this was that their complaint could not be treated by a GP.

CONCLUSIONS

Good accessibility and continuity of primary care may well reduce ED use. In some countries, it may be worthwhile to invest in more continuous relationships between patients and GPs or to eliminate factors that hamper people to use primary care (e.g. for costs or travelling).

Exploring real-time patient decision-making for acute care: a pilot study

Introduction

Research has described emergency department (ED) use patterns in detail. However, evidence is lacking on how, at the time a decision is made, patients decide if healthcare is required or where to seek care.

Methods

Using community-based participatory research methods, we conducted a mixed-methods descriptive pilot study. Due to the exploratory, hypothesis-generating nature of this research, we did not perform power calculations, and financial constraints only allowed for 20 participants. Hypothetical vignettes for the 10 most common low acuity primary care complaints (cough, sore throat, back pain, etc.) were texted to patients twice daily over six weeks, none designed to influence the patient’s decision to seek care. We conducted focus groups to gain contextual information about participant decision-making. Descriptive statistics summarized responses to texts for each scenario. Qualitative analysis of open-ended text message responses and focus group discussions identified themes associated with decision-making for acute care needs.

Results

We received text survey responses from 18/20 recruited participants who responded to 72% (1092/1512) of the texted vignettes. In 48% of the vignettes, participants reported they would do nothing, for 34% of the vignettes participants reported they would seek care with a primary care provider, and 18% of responses reported they would seek ED care. Participants were not more likely to visit an ED during “off-hours.” Our qualitative findings showed: 1) patients don’t understand when care is needed; 2) patients don’t understand where they should seek care.

Conclusion

Participants were unclear when or where to seek care for common acute health problems, suggesting a need for patient education. Similar research is necessary in different populations and regarding the role of urgent care in acute care delivery.

An Interrupted Time-Series Analysis to Assess Impact of Introduction of Co-Payment on Emergency Room Visits in Cyprus

INTRODUCTION

A co-payment fee of EUR10 was introduced in Cyprus, in order to cope with overcrowding of emergency room services. The scope of this paper is the assessment of the short-term impact of this measure.

METHODS

We used an interrupted time-series autoregressive integrated moving average model, and we analyzed official data from Cyprus' largest emergency room facility for three years.

RESULTS

Co-payment is associated with a 16% statistically significant reduction of emergency room visits. No impact was observed in categories of teenagers, children, infants, and people over 70 years old.

CONCLUSIONS

Co-payment was proven to be effective in Cyprus' emergency room setting and is expected to lessen congestion in the emergency room. The price insensitivity of people aged over 70 years, teenagers, children and infants, merits additional research for the identification of the underlying reasons.

Access to primary care and the route of emergency admission to hospital: retrospective analysis of national hospital administrative data

Background

The UK government is pursuing policies to improve primary care access, as many patients visit accident and emergency (A and E) departments after being unable to get suitable general practice appointments. Direct admission to hospital via a general practitioner (GP) averts A and E use, and may reduce total hospital costs. It could also enhance the continuity of information between GPs and hospital doctors, possibly improving healthcare outcomes.

Objective

To determine whether primary care access is associated with the route of emergency admission—via a GP versus via an A and E department.

Methods

Retrospective analysis of national administrative data from English hospitals for 2011–2012. Adults admitted in an emergency (unscheduled) for ≥1 night via a GP or an A and E department formed the study population. The measure of primary care access—the percentage of patients able to get a general practice appointment on their last attempt—was derived from a large, nationally representative patient survey. Multilevel logistic regression was used to estimate associations, adjusting for patient and admission characteristics.

Results

The analysis included 2 322 112 emergency admissions (81.9% via an A and E department). With a 5 unit increase in the percentage of patients able to get a general practice appointment on their last attempt, the adjusted odds of GP admission (vs A and E admission) was estimated to increase by 15% (OR 1.15, 95% CI 1.12 to 1.17). The probability of GP admission if ≥95% of appointment attempts were successful in each general practice was estimated to be 19.6%. This probability reduced to 13.6% when <80% of appointment attempts were successful. This equates to 139 673 fewer GP admissions (456 232 vs 316 559) assuming no change in the total number of admissions. Associations were consistent in direction across geographical regions of England.

Conclusions

Among hospital inpatients admitted as an emergency, patients registered to more accessible general practices were more likely to have been admitted via a GP (vs an A and E department). This furthers evidence suggesting that access to general practice is related to use of emergency hospital services in England. The relative merits of the two admission routes remain unclear.

Tailoring interventions: identifying predictors of poor asthma control

BACKGROUND

Determining the factors that will predict long-term asthma control is essential for improving health outcomes and decreasing the burden on the health care system. Patient-reported outcomes (PROs) on health behaviors can provide valuable information about future asthma control but have rarely been considered in previous analyses.

OBJECTIVE

To develop statistical models for evaluating the predictors of long-term asthma control using PROs such as scores of the Asthma Control Test and the Asthma Self-Efficacy Scale.

METHODS

Of 1,437 individuals contacted, 566 (39%) at baseline and 486 (34%) at follow-up completed the questionnaires, including 4 PROs (Asthma Control Test, Asthma Self-Efficacy Scale, Mini-Asthma Quality of Life Questionnaire, and Beliefs about Medication Questionnaire). Long-term asthma control was evaluated by assessing overuse of rescue medication and emergency department visits. A multivariate logistic generalized estimating equation model was fitted to evaluate the possible effect of the studied factors on asthma control.

RESULTS

The complete case generalized estimating equation analysis included 286 participants who had complete PROs at the 2 evaluation times. After adjusting for socioeconomic status and smoking status, the Mini-Asthma Quality of Life Questionnaire was a significant predictor of asthma exacerbation. For each 1-point increase on the Mini-Asthma Quality of Life Questionnaire, there was a 0.25 decrease in the odds of a patient's asthma getting out of control.

CONCLUSION

These findings suggest opportunities to decrease the burden on health care by tailoring interventions that combine PROs with other clinical and sociodemographic variables.

Improving adherence to asthma therapies

PURPOSE OF REVIEW

Adherence to asthma therapies is poor leading to unnecessary morbidity and increased use of emergency and hospital resources. Strategies to improve adherence have not been successful.

RECENT FINDINGS

Asthma adherence disease management is a clinical method to improve adherence for asthma patients. The method includes: diagnosing adherence status; identifying patient barriers leading to nonadherence; selecting specific strategies for the clinician for each barrier identified; use of patient-centered communication skills to enhance the effectiveness of the strategies employed. This approach is now being tested in multiple controlled trials.

SUMMARY

Clinicians may want to consider these strategies, in whole or in part, to improve asthma patient adherence.

Emergency Department Non-Urgent Visits and Hospital Readmissions Are Associated with Different Socio-Economic Variables in Italy

Objective

The aim of this paper was to evaluate socio-economic factors associated to poor primary care utilization by studying two specific subjects: the hospital readmission rate, and the use of the Emergency Department (ED) for non-urgent visits.

Methods

The study was carried out by the analysis of administrative database for hospital readmission and with a specific survey for non-urgent ED use.

Results

Among the 416,698 sampled admissions, 6.39% (95% CI, 6.32–6.47) of re-admissions have been registered; the distribution shows a high frequency of events in the age 65–84 years group, and in the intermediate care hospitals (51.97%; 95%CI 51.37–52.57). The regression model has shown the significant role played by age, type of structure (geriatric acute care), and deprivation index of the area of residence on the readmission, however, after adjusting for the intensity of primary care, the role of deprivation was no more significant. Non-urgent ED visits accounted for the 12.10%, (95%CI 9.38–15.27) of the total number of respondents to the questionnaire (N = 504). The likelihood of performing a non-urgent ED visit was higher among patients aged <65 years (OR 3.2, 95%CI 1.3–7.8 p = 0.008), while it was lower among those perceiving as urgent their health problem (OR 0.50, 95%CI 0.30–0.90).

Conclusions

In the Italian context repeated readmissions and ED utilization are linked to different trajectories, besides the increasing age and comorbidity of patients are the factors that are related to repeated admissions, the self-perceived trust in diagnostic technologies is an important risk factor in determining ED visits. Better use of public national health care service is mandatory, since its correct utilization is associated to increasing equity and better health care utilization.

Pre-emergency-department care-seeking patterns are associated with the severity of presenting condition for emergency department visit and subsequent adverse events: a timeframe episode analysis

Background

Many patients treated in Emergency Department (ED) visits can be treated at primary or urgent care sectors, despite the fact that a number of ED visitors seek other forms of care prior to an ED visit. However, little is known regarding how the pre-ED activity episodes affect ED visits.

Objectives

We investigated whether care-seeking patterns involve the use of health care services of various types prior to ED visits and examined the associations of these patterns with the severity of the presenting condition for the ED visit (EDVS) and subsequent events.

Methods

This retrospective observational study used administrative data on beneficiaries of the universal health care insurance program in Taiwan. The service type, treatment capacity, and relative diagnosis were used to classify pre-ED visits into 8 care types. Frequent pattern analysis was used to identify sequential care-seeking patterns and to classify 667,183 eligible pre-ED episodes into patterns. Generalized linear models were developed using generalized estimating equations to examine the associations of these patterns with EDVS and subsequent events.

Results

The results revealed 17 care-seeking patterns. The EDVS and likelihood of subsequent events significantly differed among patterns. The ED severity index of patterns differ from patterns seeking directly ED care (coefficients ranged from -0.05 to 0.13), and the odds-ratios for the likelihood of subsequent ED visits and hospitalization ranged from 1.18 to 1.86 and 1.16 to 2.84, respectively.

Conclusions

The pre-ED care-seeking patterns differ in severity of presenting condition and subsequent events that may represent different causes of ED visit. Future health policy maker may adopt different intervention strategies for targeted population to reduce unnecessary ED visit effectively.

Travel distances, socioeconomic characteristics, and health disparities in nonurgent and frequent use of Hospital Emergency Departments in South Carolina: a population-based observational study

BACKGROUND

Nonurgent use of hospital emergency departments (ED) is a controversial topic. It is thought to increase healthcare costs and reduce quality, but is also considered a symptom of unequal access to health care. In this article, we investigate whether convenience (as proxied by travel distances to the hospital ED and to the closest federally qualified health center) is associated with nonurgent ED use, and whether evidence of health disparities exist in the way vulnerable populations use the hospital ED for medical care in South Carolina.

METHODS

Our data includes 6,592,501 ED visits in South Carolina between 2005 and 2010 from the South Carolina Budget Control Board and Office of Research and Statistics. All ED visits by South Carolina residents with unmasked variables and nonmissing urgency measures, or approximately 76% of all ED visits, are used in the analysis. We perform multivariable linear regressions to estimate correlations between (1) travel distances and observable sociodemographic characteristics and (2) measures of nonurgent ED use or frequent nonurgent ED use, as defined by the New York University ED Algorithm.

RESULTS

Patients with commercial private insurance, self-pay patients, and patients with other payment sources have lower measures of nonurgent ED use the further away the ED facility is from the patients' home address. Vulnerable populations, particularly African American and Medicaid patients, have higher measures of nonurgent ED scores, and are more frequent users of the ED for both nonurgent and urgent reasons in South Carolina. At the same time, African Americans visit the hospital ED for medical conditions with higher primary care-preventable scores.

CONCLUSIONS

Contrary to popular belief, convenient access (in terms of travel distances) to hospital ED is correlated with less-urgent ED use among privately insured patients and self-pay patients in South Carolina, but not publicly insured patients. Unequal access to primary care appears to exist, as suggested by African American patients' use of the hospital ED for primary care-treatable conditions while experiencing more frequent and more severe primary care-preventable conditions.

Association between general practice characteristics and use of out-of-hours GP cooperatives

Background

The use of out-of-hours healthcare services for non-urgent health problems is believed to be related to the organisation of daytime primary care but insight into underlying mechanisms is limited. Our objective was to examine the association between daytime general practice characteristics and the use of out-of-hours care GP cooperatives.

Methods

A cross-sectional observational study in 100 general practices in the Netherlands, connected to five GP cooperatives. In each GP cooperative, we took a purposeful sample of the 10 general practices with the highest use of out-of-hours care and the 10 practices with the lowest use.

Practice and population characteristics were obtained by questionnaires, interviews, data extraction from patient registration systems and telephone accessibility measurements. To examine which aspects of practice organisation were associated with patients’ use of out-of-hours care, we performed logistic regression analyses (low versus high out-of-hours care use), correcting for population characteristics.

Results

The mean out-of-hours care use in the high use group of general practices was 1.8 times higher than in the low use group. Day time primary care practices with more young children and foreigners in their patient populations and with a shorter distance to the GP cooperative had higher out-of-hours primary care use. In addition, longer telephone waiting times and lower personal availability for palliative patients in daily practice were associated with higher use of out-of-hours care. Moreover, out-of-hours care use was higher when practices performed more diagnostic tests and therapeutic procedures and had more assistant employment hours per 1000 patients.

Several other aspects of practice management showed some non-significant trends: high utilising general practices tended to have longer waiting times for non-urgent appointments, lower availability of a telephone consulting hour, lower availability for consultations after 5 p.m., and less frequent holiday openings.

Conclusions

Besides patient population characteristics, organisational characteristics of general practices are associated with lower use of out-of-hours care. Improving accessibility and availability of day time primary day care might be a potential effective way to improve the efficient use of out-of-hours care services.

Evaluation of the influence of a pharmacist-led patient-centered medication therapy management and reconciliation service in collaboration with emergency department physicians

BACKGROUND

The implementation of the Patient Protection and Affordable Care Act is anticipated to increase the frequency of emergency department (ED) visits. Therefore, there is a critical need to improve the quality of care transitions among ED patients from ED to outpatient services. 

OBJECTIVE

To evaluate the effect of systematic implementation of a pharmacist-led patient-centered approach to medication therapy management and reconciliation service (MRS) in the ED on patient utilization of available health care services.

METHODS

A single institution prospective randomized cohort study with 90-day postvisit observation randomized patients into 2 groups: (1) medication therapy management reconciliation service following a patient-centered approach (MRS) or (2) usual care provided by the institution (non-MRS). To align patient enrollment with availability of other primary care services, subjects were enrolled during weekday daytime hours. Data for the 90 days before and after the index ED visit were matched in all analyses. Generalized estimating equations evaluated any primary care (PC), urgent care (UC), and ED visits during the 90 days post-index ED visit, adjusted by age and sex and weighted by survival time. Generalized linear models evaluated the average number of ED visits during that period, adjusted by age and sex and weighted by survival time. Data were analyzed for all adult patients (ADLTS), aged ≥ 18 years, and the subpopulation taking 1 or more prescribed daily medication at the time of the index ED visit (ADLTS1+)-the patients expected to receive greatest benefit from an MRS program.

RESULTS

ADLTS MRS patients were 1.9 more likely than non-MRS patients to visit their PC providers (mean difference 0.15, P  less than  0.001). Similarly, ADLTS1+ MRS patients were 1.5 times more likely to visit their PC providers (mean difference 0.10, P = 0.026). Although ADLT MRS patients were less likely to visit the UC, this was not significant. However, ADLTS1+ MRS patients were significantly less likely than non-MRS patients (OR = 0.5, 95% CI = 0.3-0.9) to visit the UC. No significant difference was seen in ED visits.

CONCLUSIONS

The implementation of a patient-centered approach to medication therapy management and reconciliation improved the odds of patients visiting their PC providers, a positive first step in transitioning patients toward an appropriate use of PC services.

Travel distance and sociodemographic correlates of potentially avoidable emergency department visits in California, 2006-2010: an observational study

INTRODUCTION

Use of the hospital emergency department (ED) for medical conditions not likely to require immediate treatment is a controversial topic. It has been faulted for ED overcrowding, increased expenditures, and decreased quality of care. On the other hand, such avoidable ED utilization may be a manifestation of barriers to primary care access.

METHODS

A random 10% subsample of all ED visits with unmasked variables, or approximately 7.2% of all ED visits in California between 2006 and 2010 are used in the analysis. Using panel data methods, we employ linear probability and fractional probit models with hospital fixed effects to analyze the associations between avoidable ED utilization in California and observable patient characteristics. We also test whether shorter estimated road distances to the hospital ED are correlated with non-urgent ED utilization, as defined by the New York University ED Algorithm. We then investigate whether proximity of a Federally Qualified Health Center (FQHC) is correlated with reductions in non-urgent ED utilization among Medicaid patients.

RESULTS

We find that relative to the reference group of adults aged 35-64, younger patients generally have higher scores for non-urgent conditions and lower scores for urgent conditions. However, elderly patients (≥65) use the ED for conditions more likely to be urgent. Relative to male and white patients, respectively, female patients and all identified racial and ethnic minorities use the ED for conditions more likely to be non-urgent. Patients with non-commercial insurance coverage also use the ED for conditions more likely to be non-urgent. Medicare and Medicaid patients who live closer to the hospital ED have higher probability scores for non-emergent visits. However, among Medicaid enrollees, those who live in zip codes with an FQHC within 0.5 mile of the zip code population centroid visit the ED for medical conditions less likely to be non-emergent.

CONCLUSIONS

These patterns of ED utilization point to potential barriers to care among historically vulnerable groups, observable even when using rough estimates of travel distances and avoidable ED utilization.

Children's emergency department use for asthma, 2001-2010

OBJECTIVES

Although the emergency department (ED) provides essential care for severely ill or injured children, past research has shown that children often visit the ED for potentially preventable illnesses, including asthma. We sought to determine how children's rate of ED visits for asthma has changed over the last decade and to analyze what factors are associated with a child's potentially preventable ED visit for asthma.

METHODS

We retrospectively analyzed ED visits by children aged 2 to 17 from 2001 to 2010 using data from the National Hospital Ambulatory Medical Care Survey. Visits were classified as potentially preventable asthma visits by mapping ICD-9-CM diagnosis codes to the Agency for Healthcare Research and Quality's asthma pediatric quality indicator. We examined trends in the annual rate of ED visits for asthma per 1000 children using a weighted linear regression model. Finally, we used multivariate logistic regression to determine what demographic, clinical, and structural factors were associated with a child's ED visit being for a potentially preventable asthma crisis.

RESULTS

The rate of children's ED visits for asthma increased 13.3% between 2001 and 2010, from 8.2 to 9.3 visits per 1000 children (P = .26). ED visits by children who were younger, male, racial or ethnic minorities, insured with Medicaid/Children's Health Insurance Program, and visiting between 11 pm and 7 am were more likely to be for potentially preventable asthma crises.

CONCLUSIONS

Although the overall rate of potentially preventable ED visits for asthma did not significantly change over the last decade, racial, insurance-based, and other demographic disparities in the likelihood of a preventable asthma-related ED visit persist.

Distance effects on the accessibility to emergency departments in Portugal

Distance patients have to travel has shown to influence demand for several health services. Our work looks at this effect on the utilization of Emergency Departments (ED) in Portugal. We build upon previous works by taking into account both the severity of emergency visits and the type of ED and by including a set of other variables that have shown to influence ED utilization. Overall, we find distance-elasticity for emergency care that ranges from -1 to -2 (a 10% increase in distance to ED results in a 10-20% decrease in ED utilization), with low-severity demand having the highest distance-elasticity and high-severity demand the lowest. We also show that Primary Health Care, and particularly some new typology of health centers in Portugal, negatively affects ED utilization. Our results provide evidence that distance enters in the budget constraints patients face when seeking health care.

Identification, summary and comparison of tools used to measure organizational attributes associated with chronic disease management within primary care settings

RATIONALE, AIMS AND OBJECTIVES

Given the increasing emphasis being placed on managing patients with chronic diseases within primary care, there is a need to better understand which primary care organizational attributes affect the quality of care that patients with chronic diseases receive. This study aimed to identify, summarize and compare data collection tools that describe and measure organizational attributes used within the primary care setting worldwide.

METHODS

Systematic search and review methodology consisting of a comprehensive and exhaustive search that is based on a broad question to identify the best available evidence was employed.

RESULTS

A total of 30 organizational attribute data collection tools that have been used within the primary care setting were identified. The tools varied with respect to overall focus and level of organizational detail captured, theoretical foundations, administration and completion methods, types of questions asked, and the extent to which psychometric property testing had been performed. The tools utilized within the Quality and Costs of Primary Care in Europe study and the Canadian Primary Health Care Practice-Based Surveys were the most recently developed tools. Furthermore, of the 30 tools reviewed, the Canadian Primary Health Care Practice-Based Surveys collected the most information on organizational attributes.

CONCLUSIONS

There is a need to collect primary care organizational attribute information at a national level to better understand factors affecting the quality of chronic disease prevention and management across a given country. The data collection tools identified in this review can be used to establish data collection strategies to collect this important information.

Clinic type and patient characteristics affecting time to resolution after an abnormal cancer-screening exam

BACKGROUND

Research shows that multilevel factors influence healthcare delivery and patient outcomes. The study goal was to examine how clinic type [academic medical center (AMC) or federally qualified health center (FQHC)] and patient characteristics influence time to resolution (TTR) among individuals with an abnormal cancer-screening test enrolled in a patient navigation (PN) intervention.

METHODS

Data were obtained from the Ohio Patient Navigation Research Project, a group-randomized trial of 862 patients from 18 clinics in Columbus, Ohio. TTR of patient after an abnormal breast, cervical, or colorectal screening test and the clinics' patient and provider characteristics were obtained. Descriptive statistics and Cox shared frailty proportional hazards regression models of TTR were used.

RESULTS

The mean patient age was 44.8 years and 71% of patients were white. In models adjusted for study arm, FQHC patients had a 39% lower rate of resolution than AMC patients (P = 0.004). Patient factors of having a college education, private insurance, higher income, and being older were significantly associated with lower TTR. After adjustment for factors that substantially affected the effect of clinic type (patient insurance status, education level, and age), clinic type was not significantly associated with TTR.

CONCLUSIONS

These results suggest that TTR among individuals participating in PN programs are influenced by multiple socioeconomic patient-level factors rather than clinic type. Consequently, PN interventions should be tailored to address socioeconomic status factors that influence TTR.

IMPACT

These results provide clues regarding where to target PN interventions and the importance of recognizing predictors of TTR according to clinic type.

Association of Medicare and Medicaid insurance with increasing primary care-treatable emergency department visits in the United States

OBJECTIVES

Policymakers have increasingly focused on emergency department (ED) utilization for primary care-treatable conditions as a potentially avoidable source of rising health care costs. The objective was to determine the association of health insurance type and arrival time, as indicators of limited availability of primary care, with primary care-treatable classification of ED visits.

METHODS

This was a retrospective analysis of a nationally representative sample of 241,167 ED visits from the 1997 to 2009 National Hospital Ambulatory Medical Care Surveys (NHAMCS). Probabilities of ED visits being primary care-treatable were categorized based on the primary International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) code. The association of health insurance type and arrival time was determined with the average probability of the primary diagnosis being primary care-treatable using multivariable linear regression.

RESULTS

Compared to privately insured visits, Medicaid visits had a 1.7% (95% confidence interval [CI] = 1.2% to 2.2%) and uninsured visits a 2.4% (95% CI = 1.9% to 3.0%) higher probability of primary care-treatable classification, while Medicare visits had a 1.4% (95% CI = 0.7% to 2.0%) lower probability during the overall study period. Compared to business hours, weekend visits had a 1.5% (95% CI = 1.0% to 2.0%) higher probability of being primary care-treatable during the overall study period. From 1997 to 2009, the overall adjusted probability of ED visits being primary care-treatable increased by 0.19% (95% CI = 0.10 to 0.28) per year. This probability increased at a rate of 0.52% per year for Medicare visits (95% CI = 0.38% to 0.65%), more than double that of Medicaid visits (0.25% per year, 95% CI = 0.13% to 0.37%). By contrast, there was no significant change from 1997 to 2009 in the average probability of ED visits being primary care-treatable by privately insured (0.05% per year, 95% CI = -0.07 to 0.16) or uninsured (0.00% per year, 95% CI = -0.12 to 0.13) individuals.

CONCLUSIONS

These findings add to prior work that implicates insurance type and arrival time in the variation of primary care-treatable ED visits. Although primary care-treatable classification of ED visits was most associated with uninsured or Medicaid visits, this classification increased most rapidly among Medicare visits during the study period.

Toward a strategy of patient-centered access to primary care

Patient-centered access (PCA) to primary care services is rapidly becoming an imperative for efficiently delivering high-quality health care to patients. To enhance their PCA-related efforts, some medical practices and health systems have begun to use various tactics, including team-based care, satellite clinics, same-day and group appointments, greater use of physician assistants and nurse practitioners, and remote access to health services. However, few organizations are addressing the PCA imperative comprehensively by integrating these various tactics to develop an overall PCA management strategy. Successful integration means taking into account the changing competitive and reimbursement landscape in primary care, conducting an evidence-based assessment of the barriers and benefits of PCA implementation, and attending to the particular needs of the institution engaged in this important effort. This article provides a blueprint for creating a multifaceted but coordinated PCA strategy-one aimed squarely at making patient access a centerpiece of how health care is delivered. The case of a Wisconsin-based health system is used as an illustrative example of how other institutions might begin to conceive their fledgling PCA strategies without proposing it as a one-size-fits-all model.

Primary care access and emergency room use among older veterans

BACKGROUND

Patient access to primary care is often noted to be poor. Improving access may reduce emergency room (ER) visits.

OBJECTIVE

To examine the relationship between primary care access and ER use and to test whether this relationship is moderated by having a continuous relationship with a Primary Care Provider (PCP) (or if the PCP is the near-sole provider of care for patients).

DESIGN AND PATIENTS

A longitudinal retrospective study of 627,276 patients receiving primary care from 6,398 primary care providers (PCPs) nationally within the Veterans Health Administration (VHA) in 2009. We tracked weekly changes in PCP-level appointment availability.

MEASUREMENTS

The number of a PCP's patients who went to the ER in a given week.

RESULTS

Among all PCPs, being absent from patient care for the week had no effect on whether that PCP's patients used the ER in that week (incident rate ratio (IRR) 0.997, p = 0.70). However, among PCPs who were near-sole providers of care, a PCP's absence for a week or more had a statistically significant effect on ER visits (IRR 1.04, p = 0.01). The percentage of a PCP's weekly appointment slots that were fully booked (booking density) had no significant effect on whether their patients used the ER in that week among all PCPs. However, among near-sole providers of care, a 10-percentage point increase in the booking density changed the IRR of ER visits in that week by 1.005 (p = 0.08) and by 1.006 on weekdays (p = 0.07).

CONCLUSIONS

Patients' access to their PCP had a small effect on whether those patients used the ER among PCPs whose patients rarely saw another PCP. Among other PCPs, there was no effect of PCP access on ER use. These results suggest that sharing patient-care responsibilities across PCPs may be effective in improving access to care and decreasing unnecessary ER use.

Which features of primary care affect unscheduled secondary care use? A systematic review

OBJECTIVES

To conduct a systematic review to identify studies that describe factors and interventions at primary care practice level that impact on levels of utilisation of unscheduled secondary care.

SETTING

Observational studies at primary care practice level.

PARTICIPANTS

Studies included people of any age of either sex living in Organisation for Economic Co-operation and Development (OECD) countries with any health condition.

PRIMARY AND SECONDARY OUTCOME MEASURES

The primary outcome measure was unscheduled secondary care as measured by emergency department attendance and emergency hospital admissions.

RESULTS

48 papers were identified describing potential influencing features on emergency department visits (n=24 studies) and emergency admissions (n=22 studies). Patient factors associated with both outcomes were increased age, reduced socioeconomic status, lower educational attainment, chronic disease and multimorbidity. Features of primary care affecting unscheduled secondary care were more complex. Being able to see the same healthcare professional reduced unscheduled secondary care. Generally, better access was associated with reduced unscheduled care in the USA. Proximity to healthcare provision influenced patterns of use. Evidence relating to quality of care was limited and mixed.

CONCLUSIONS

The majority of research was from different healthcare systems and limited in the extent to which it can inform policy. However, there is evidence that continuity of care is associated with reduced emergency department attendance and emergency hospital admissions.

Do difficulties in accessing in-hours primary care predict higher use of out-of-hours GP services? Evidence from an English National Patient Survey

Introduction

It is believed that some patients are more likely to use out-of-hours primary care services because of difficulties in accessing in-hours care, but substantial evidence about any such association is missing.

Methods

We analysed data from 567 049 respondents to the 2011/2012 English General Practice Patient Survey who reported at least one in-hours primary care consultation in the preceding 6 months. Of those respondents, 7% also reported using out-of-hours primary care. We used logistic regression to explore associations between use of out-of-hours primary care and five measures of in-hours access (ease of getting through on the telephone, ability to see a preferred general practitioner, ability to get an urgent or routine appointment and convenience of opening hours). We illustrated the potential for reduction in use of out-of-hours primary care in a model where access to in-hours care was made optimal.

Results

Worse in-hours access was associated with greater use of out-of-hours primary care for each access factor. In multivariable analysis adjusting for access and patient characteristic variables, worse access was independently associated with increased out-of-hours use for all measures except ease of telephone access. Assuming these associations were causal, we estimated that an 11% relative reduction in use of out-of-hours primary care services in England could be achievable if access to in-hours care were optimal.

Conclusions

This secondary quantitative analysis provides evidence for an association between difficulty in accessing in-hours care and use of out-of-hours primary care services. The findings can motivate the development of interventions to improve in-hour access.

Emergency department waiting room: many requests, many insured and many primary care physician referrals

Background

Increase in waiting time often results in patients leaving the emergency department (ED) without being seen, ultimately decreasing patient satisfaction. We surveyed low-acuity patients in the ED waiting room to understand their preferences and expectations.

Methods

An IRB approved, 42-item survey was administered to 400 adult patients waiting in the ED waiting room for >15 min from April to August 2010. Demographics, visit reasons, triage and waiting room facility preferences were collected.

Results

The mean age of patients was 38.9 years (SD = 14.8), and 52.5% were females. About 53.8% of patients were employed, 79.4% had access to a primary care physician (PCP), and 17% did not have any medical insurance. The most common complaint was pain. A total of 44.4% respondents reported that they believed their problems were urgent and required immediate attention, prompting them to come to the ED, while 14.6% reported that they could not get a timely PCP appointment, and 42.9% were actually referred by their PCP to come to the ED. About 57.7% of patients considered leaving the ED if the waiting times were too long. The mean acceptable waiting time before leaving ED was 221 min (SD = 194; median 180 min, IQR 120–270). A total of 39.1% survey respondents reported being most comfortable being triaged by a physician. Respondents were least comfortable being triaged by residents. On analyzing waiting room expectations for the survey respondents, we found that 70% of the subjects wanted a better estimate of waiting time and 43.5% wanted better information on reasons for the long wait.

Conclusion

Contrary to popular belief, at our ED a large proportion of low-acuity patients has a PCP and is medically insured. Providing patients with appropriate reasons for the wait, an accurate estimate of waiting time and creating separate areas to examine minor illness/injuries would increase patient satisfaction within our population subset.

Access to primary care and visits to emergency departments in England: a cross-sectional, population-based study

BACKGROUND

The number of visits to hospital emergency departments (EDs) in England has increased by 20% since 2007-08, placing unsustainable pressure on the National Health Service (NHS). Some patients attend EDs because they are unable to access primary care services. This study examined the association between access to primary care and ED visits in England.

METHODS

A cross-sectional, population-based analysis of patients registered with 7,856 general practices in England was conducted, for the time period April 2010 to March 2011. The outcome measure was the number of self-referred discharged ED visits by the registered population of a general practice. The predictor variables were measures of patient-reported access to general practice services; these were entered into a negative binomial regression model with variables to control for the characteristics of patient populations, supply of general practitioners and travel times to health services. MAIN RESULT AND CONCLUSION: General practices providing more timely access to primary care had fewer self-referred discharged ED visits per registered patient (for the most accessible quintile of practices, RR = 0.898; P<0.001). Policy makers should consider improving timely access to primary care when developing plans to reduce ED utilisation.

The impact of unstable housing on emergency department use in a cohort of HIV-positive people in a Canadian setting

The social-structural challenges experienced by people living with HIV (PHA) have been shown to contribute to increased use of the emergency department (ED). This study identified factors associated with frequent and nonurgent ED use within a cohort of people accessing antiretroviral therapy (ART) in a Canadian setting. Interviewer-administered surveys collected socio-demographic information; clinical variables were obtained through linkages with the provincial drug treatment registry; and ED admission data were abstracted from the Department of Emergency Medicine database. Multivariate logistic regression was used to compute odds of frequent and nonurgent ED use. Unstable housing was independently associated with ED use (adjusted odds ratio [AOR] =1.94, 95% confidence interval [CI] 1.24-3.04]), having three or more ED visits within 6 months of the interview date [AOR: 2.03 (95% CI: 1.07-3.83)] and being triaged as nonurgent (AOR = 2.71, 95% CI: 1.19-6.17). Frequent and nonurgent use of the ED in this setting is associated with conditions requiring interventions at the social-structural level. Supportive housing may contribute to decreased health-care costs and improved health outcomes amongst marginalized PHA.

Primary care: current problems and proposed solutions

In 2005, approximately 400,000 people provided primary medical care in the United States. About 300,000 were physicians, and another 100,000 were nurse practitioners and physician assistants. Yet primary care faces a growing crisis, in part because increasing numbers of U.S. medical graduates are avoiding careers in adult primary care. Sixty-five million Americans live in what are officially deemed primary care shortage areas, and adults throughout the United States face difficulty obtaining prompt access to primary care. A variety of strategies are being tried to improve primary care access, even without a large increase in the primary care workforce.

After-hours access to primary care practices linked with lower emergency department use and less unmet medical need

One goal of the Affordable Care Act is to improve patients' access to primary care and the coordination of that care. An important ingredient in achieving that goal is ensuring that patients have access to their primary care practice outside of regular business hours. This analysis of the 2010 Health Tracking Household Survey found that among people with a usual source of primary care, 40.2 percent reported that their practice offered extended hours, such as at night or on weekends. The analysis also found that one in five people who attempted after-hours contact with their primary care provider reported it was "very difficult" or "somewhat difficult" to reach a clinician. Those who reported less difficulty contacting a clinician after hours had significantly fewer emergency department visits (30.4 percent compared to 37.7 percent) and lower rates of unmet medical need (6.1 percent compared to 13.7 percent) than people who experienced more difficulty. The findings provide a valuable baseline on after-hours access, especially as patient-centered medical homes and accountable care organizations expand. Increasing support to primary care practices to offer or coordinate after-hours care may help reduce rates of emergency department use and unmet medical need.

Comparison of primary physician patterns of and attitudes on emergency department use

OBJECTIVE

This study aimed to compare physician viewpoints and clinic patterns between primary care providers (PCPs) with high patient emergency department (ED) use (HU) and PCPs with low patient ED use (LU).

METHODS

We conducted a mixed methods descriptive study of quantitative and qualitative data of 22 practices. We compared admission rates, American Academy of Pediatrics guideline adherence, efficiency, medical complexity, and patient satisfaction. Primary care provider interviews regarding ED use practices and perspectives were coded and inductively analyzed using Atlas 6.0 for themes.

RESULTS

Compared with LU, the HU group had a higher admission rate (92 vs 41 admissions per 1000 members, P = 0.005), lower scores in adherence to American Academy of Pediatrics guidelines, and higher scores in satisfaction overall. There were no significant differences in efficiency, medical complexity, PCP communications, timeliness for appointment, satisfaction with after-hour care or likelihood of PCP referral. All PCPs described the EDs' purpose as for things they "cannot handle." The LU group was more likely to identify the ED for emergencies, whereas the HU group had a broader, more ambiguous definition of what they "cannot handle," with parental anxiety identified as a significant factor. In addition, the LU group recognized the need for more parental education about ED use.

CONCLUSIONS

Primary care providers with low patient ED use were more likely to describe the EDs' purpose as being for emergencies and to recognize a need for more parental education about the use of the ED. All physicians struggled with reassuring parents.

After-hours care and its coordination with primary care in the U.S

BACKGROUND

Despite expectations that medical homes provide "24 × 7 coverage" there is little to guide primary care practices in developing sustainable models for accessible and coordinated after-hours care.

OBJECTIVE

To identify and describe models of after-hours care in the U.S. that are delivered in primary care sites or coordinated with a patient's usual primary care provider.

DESIGN

Qualitative analysis of data from in-depth telephone interviews.

SETTING

Primary care practices in 16 states and the organizations they partner with to provide after-hours coverage.

PARTICIPANTS

Forty-four primary care physicians, practice managers, nurses and health plan representatives from 28 organizations.

APPROACH

Analyses examined after-hours care models, facilitators, barriers and lessons learned.

RESULTS

Based on 28 organizations interviewed, five broad models of after-hours care were identified, ranging in the extent to which they provide continuity and patient access. Key themes included: 1) The feasibility of a model varies for many reasons, including patient preferences and needs, the local health care market supply, and financial compensation; 2) A shared electronic health record and systematic notification procedures were extremely helpful in maintaining information continuity between providers; and 3) after-hours care is best implemented as part of a larger practice approach to access and continuity.

CONCLUSION

After-hours care coordinated with a patient's usual primary care provider is facilitated by consideration of patient demand, provider capacity, a shared electronic health record, systematic notification procedures and a broader practice approach to improving primary care access and continuity. Payer support is important to increasing patients' access to after-hours care.

Extended office hours and health care expenditures: a national study

PURPOSE

A key component of primary care improvement efforts is timely access to care; however, little is known regarding the effects of extended (evening and weekend) office hours on health care use and outcomes. We examined the association between reported access to extended office hours and both health care expenditures and mortality.

METHODS

We analyzed data from individuals aged 18 to 90 years responding to the 2000-2008 Medical Expenditure Panel Surveys reporting access or no access to extended hours via a usual source of care in 2 successive years (year 1 and year 2; N = 30,714). Dependent variables were year 2 total health care expenditures and, for those enrolled in 2000-2005, all-cause mortality through 2006. Covariates were year 1 sociodemographics and health care use, and year 2 health insurance, health status, and chronic conditions. We conducted further analyses, progressively adjusting for year 2 use, to explore mechanisms.

RESULTS

Total expenditures were 10.4% lower (95% confidence interval, 7.2%-13.4%) among patients reporting access to extended hours in both years vs neither year. Adjustment for year 2 prescription drug expenditures, and to a lesser extent, office visit-related expenditures (but not total prescriptions or office visits, or emergency and inpatient expenditures) attenuated this relationship. Extended-hours access was not statistically associated with mortality.

CONCLUSIONS

Respondents reporting a usual source of care offering evening and weekend office hours had lower total health care expenditures than those without extended-hours access, an association related to lower prescription drug and office visit-related (eg, testing) expenditures, without adverse effects on mortality. Although requiring further study, extended office hours may be associated with more judicious use of health care resources.

Risk factors for increased ED utilization in a multinational cohort of children with sickle cell disease

OBJECTIVES

The objective was to identify clinical, social, and environmental risk factors for increased emergency department (ED) use in children with sickle cell disease (SCD).

METHODS

This study was a secondary analysis of ED utilization data from the international multicenter Silent Cerebral Infarct Transfusion (SIT) trial. Between December 2004 and June 2010, baseline demographic, clinical, and laboratory data were collected from children with SCD participating in the trial. The primary outcome was the frequency of ED visits for pain. A secondary outcome was the frequency of ED visits for acute chest syndrome.

RESULTS

The sample included 985 children from the United States, Canada, England, and France, for a total of 2,955 patient-years of data. There were 0.74 ED visits for pain per patient-year. A past medical history of asthma was associated with an increased risk of ED utilization for both pain (rate ratio [RR] = 1.28, 95% confidence interval [CI] = 1.04 to 1.58) and acute chest syndrome (RR = 1.60, 95% CI = 1.03 to 2.49). Exposure to environmental tobacco smoke in the home was associated with 73% more ED visits for acute chest syndrome (RR = 1.73, 95% CI = 1.09 to 2.74). Each $10,000 increase in household income was associated with 5% fewer ED visits for pain (RR = 0.95, 95% CI = 0.91 to 1.00, p = 0.05). The association between low income and ED utilization was not significantly different in the United States versus countries with universal health care (p = 0.51).

CONCLUSIONS

Asthma and exposure to environmental tobacco smoke are potentially modifiable risk factors for greater ED use in children with SCD. Low income is associated with greater ED use for SCD pain in countries with and without universal health care.

Effectiveness of organizational interventions to reduce emergency department utilization: a systematic review

Background

Emergency department (ED) utilization has dramatically increased in developed countries over the last twenty years. Because it has been associated with adverse outcomes, increased costs, and an overload on the hospital organization, several policies have tried to curb this growing trend. The aim of this study is to systematically review the effectiveness of organizational interventions designed to reduce ED utilization.

Methodology/Principal Findings

We conducted electronic searches using free text and Medical Subject Headings on PubMed and The Cochrane Library to identify studies of ED visits, re-visits and mortality. We performed complementary searches of grey literature, manual searches and direct contacts with experts. We included studies that investigated the effectiveness of interventions designed to reduce ED visits and the following study designs: time series, cross-sectional, repeated cross-sectional, longitudinal, quasi-experimental studies, and randomized trial. We excluded studies on specific conditions, children and with no relevant outcomes (ED visits, re-visits or adverse events). From 2,348 potentially useful references, 48 satisfied the inclusion criteria. We classified the interventions in mutually exclusive categories: 1) Interventions addressing the supply and accessibility of services: 25 studies examined efforts to increase primary care physicians, centers, or hours of service; 2) Interventions addressing the demand for services: 6 studies examined educational interventions and 17 examined barrier interventions (gatekeeping or cost).

Conclusions/Significance

The evidence suggests that interventions aimed at increasing primary care accessibility and ED cost-sharing are effective in reducing ED use. However, the rest of the interventions aimed at decreasing ED utilization showed contradictory results. Changes in health care policies require rigorous evaluation before being implemented since these can have a high impact on individual health and use of health care resources.

National study of barriers to timely primary care and emergency department utilization among Medicaid beneficiaries

STUDY OBJECTIVE

We compare the association between barriers to timely primary care and emergency department (ED) utilization among adults with Medicaid versus private insurance.

METHODS

We analyzed 230,258 adult participants of the 1999 to 2009 National Health Interview Survey. We evaluated the association between 5 specific barriers to timely primary care (unable to get through on telephone, unable to obtain appointment soon enough, long wait in the physician's office, limited clinic hours, lack of transportation) and ED utilization (≥1 ED visit during the past year) for Medicaid and private insurance beneficiaries. Multivariable logistic regression models adjusted for demographics, socioeconomic status, health conditions, outpatient care utilization, and survey year.

RESULTS

Overall, 16.3% of Medicaid and 8.9% of private insurance beneficiaries had greater than or equal to 1 barrier to timely primary care. Compared with individuals with private insurance, Medicaid beneficiaries had higher ED utilization overall (39.6% versus 17.7%), particularly among those with barriers (51.3% versus 24.6% for 1 barrier and 61.2% versus 28.9% for ≥2 barriers). After adjusting for covariates, Medicaid beneficiaries were more likely to have barriers (adjusted odds ratio [OR] 1.41; 95% confidence interval [CI] 1.30 to 1.52) and higher ED utilization (adjusted OR 1.48; 95% CI 1.41 to 1.56). ED utilization was even higher among Medicaid beneficiaries with 1 barrier (adjusted OR 1.66; 95% CI 1.44 to 1.92) or greater than or equal to 2 barriers (adjusted OR 2.01; 95% CI 1.72 to 2.35) compared with that for individuals with private insurance and barriers.

CONCLUSION

Compared with individuals with private insurance, Medicaid beneficiaries were affected by more barriers to timely primary care and had higher associated ED utilization. Expansion of Medicaid eligibility alone may not be sufficient to improve health care access.

Primary care attributes and mortality: a national person-level study

PURPOSE

Research demonstrates an association between the geographic concentration of primary care clinicians and mortality in the area, but there is limited evidence of a mortality benefit of primary care at the individual patient level. We examined whether patient-reported access to selected primary care attributes, including some emphasized in the medical home literature, is associated with lower individual mortality risk.

METHODS

We analyzed data from 2000-2005 Medical Expenditure Panel Survey respondents aged 18 to 90 years (N = 52,241), linked to the National Death Index through 2006. A score was constructed from 5 yes/no items assessing whether the respondent's usual source of care had 3 attributes: comprehensiveness, patient-centeredness, and enhanced access. Scores ranged from 0 to 1 (higher scores = more attributes). We examined the association between the primary care attributes score and mortality during up to 6 years of follow-up using Cox survival analysis, adjusted for social, demographic, and health-related characteristics.

RESULTS

Racial/ethnic minorities, poorer and less educated persons, individuals without private insurance, healthier persons, and residents of regions other than the Northeast reported less access to primary care attributes than others. The primary care attributes score was inversely associated with mortality (adjusted hazard ratio = 0.79; 95% confidence interval, 0.64-0.98; P = .03); supplementary analyses showed mortality decreased linearly with increasing score.

CONCLUSIONS

Greater reported patient access to selected primary care attributes was associated with lower mortality. The findings support the current interest in ensuring that patients have access to a medical home encompassing these attributes.

Primary care access and its relationship with emergency department utilisation: an observational, cross-sectional, ecological study

BACKGROUND

Recent health service policies in the UK have focused on improving primary care access in order to reduce the use of costly emergency department services, even though the relationship between the two is based on weak or little evidence. Research is required to establish whether improving primary care access can influence emergency department attendance.

AIM

To ascertain whether a relationship exists between the degree of access to GP practices and avoidable emergency department attendances in an inner-London primary care trust (PCT).

DESIGN AND SETTING

Observational, cross-sectional ecological study in 68 general practices in Brent Primary Care Trust, north London, UK.

METHOD

GP practices were used as the unit of analysis and avoidable emergency department attendance as the dependent variable. Routinely collected data from GP practices, Hospital Episode Statistics, and census data for the period covering 2007-2009 were used across three broad domains: GP access characteristics, population characteristics, and health status aggregated to the level of the GP practice. Multiple linear regression was used to ascertain which variables account for the variation in emergency department attendance experienced by patients registered to each GP practice.

RESULTS

None of the GP access variables accounted for the variation in emergency department attendance. The only variable that explained this variance was the Index of Multiple Deprivation (IMD). For every unit increase in IMD score of the GP practice, there would be an increase of 6.13 (95% CI = 4.56, 7.70) per 1000 patients per year in emergency department attendances. This accounted for 47.9% of the variance in emergency department attendances in Brent.

CONCLUSION

Avoidable emergency department attendance appears to be mostly driven by underlying deprivation rather than by the degree of access to primary care.
