Knowledge and practices of generalist and specialist physicians regarding drug therapy for acute myocardial infarction

Barriers Impact the Primary Healthcare Providers When Dealing With Emergency Cases: A Cross-Sectional Study in Al-Ahsa, Saudi Arabia

Introduction Being the first in-line care providers, primary healthcare (PHC) physicians may encounter all forms of medical emergencies, ranging from minor complaints to major life-threatening events; therefore, this study aims to assess the PHC physicians' knowledge and attitude related to the diagnosis and management of emergency cases as well as their preferences for emergency medicine training courses and their preferred methods of training. Methods A descriptive cross-sectional study was conducted among physicians working at PHC in Al-Ahsa, Saudi Arabia, between November and December 2023, excluding those who do not work at PHC. The minimum required sample size was 192. A self-administered online questionnaire was developed using Google Forms and distributed conveniently through social media platforms. It consists of 22 items categorized into four sections: The first section focused on demographic information; the second section assessed knowledge related to the diagnosis and management of emergency cases commonly encountered in PHC, along with actual management experiences; the third section gauged physicians' attitudes, and the fourth section explored participants' preferences for emergency medicine courses and their preferred methods of training in this field. The Kruskal-Wallis rank sum and Wilcoxon rank sum tests were employed to identify predictors of knowledge and attitude. Results The study involved 193 participants, with 96 (50%) females and a median age of 30 years. The participants included 43 (22%) consultants, 69 (36%) family residents, 30 (16%) general practitioners, and 50 (26%) specialists. Participants reported a median of 4.0 years of experience in PHC in Saudi Arabia. The majority, 69 (36%), reported working in the hospital emergency department, with a reported median duration of three months. Roughly 84% of PHC physicians had a positive attitude toward emergency cases diagnosis and management, while 92% showed fair diagnostic knowledge of emergency cases, and 73% showed fair management knowledge. Higher knowledge in the diagnosis and management of PHC was linked to increasing age, being consultants, being employed in the emergency department, and having higher years of experience in PHC (p < 0.05). A positive attitude toward PHC was found to be associated with working as a consultant and being employed in the emergency department (p < 0.05). Approximately 133 (68.9%) expressed a preference for a course in wound care trauma, followed by central nervous system emergencies (n = 124, 64.2%), coronary artery disease emergencies (n = 116, 60.1%), and obstetrics/gynecologic emergencies (n = 114, 59.1%) with 160 (82.9%) favored training through practice in PHC under supervision of qualified staff. Conclusion While many PHC centers are well equipped and prepared for early stabilization and management of emergency cases, PHC physicians showed low competency in dealing with emergency cases. This indicates a great need for enhancing physician's knowledge and skills regarding emergency situations. Nevertheless, courses like basic life support (BLS) and advanced trauma life support (ATLS) should be the bare minimum requirements for PHC physicians. Mote advance training and lectures should be organized to enhance PHC physician competencies to deal with different emergencies.

The Effectiveness of Mobile Cloud 12-Lead Electrocardiogram Transmission System in Patients with ST-Segment Elevation Myocardial Infarction

Backgroundand Objectives: Delay of reperfusion therapy is related to high mortality in cases of ST-segment elevation myocardial infarction (STEMI). Guidelines emphasize that the first-medical-contact-to-balloon (FMCTB) time should be within 90 min. A mobile cloud-based 12-lead electrocardiogram (MC-ECG) transmission system might be useful in such cases, especially in rural areas. Materials and Methods: From April 2019 to June 2021, both an MC-ECG transmission system and the conventional method in which a physician checks the ECG in a hospital (Conventional) were used for transport by emergency medical services in Shin-Yukuhashi Hospital, Fukuoka, Japan. During this period, 8684 consecutive patients were transported to this hospital. Among them, we investigated 48 STEMI patients. The MC-ECG group (n = 23) and the Conventional group (n = 25) were enrolled. Results: There was no significant difference in FMCTB time between the MC-ECG and Conventional groups (MC-ECG: 72.0 (60.5–107) min vs. Conventional: 80.0 (63.0–92.0) min, p = 0.77). The length of hospital stay in the MC-ECG group was significantly shorter than that in the Conventional group (12.0 (10.0–15.0) days vs. 16.0 (12.0–19.0) days, p = 0.039). The logistic regression model showed that patients’ non-use of MC-ECG was associated with a risk of more than 15-day length of hospital stay with an adjusted odd ratio of 0.08 (95% CI: 0.013–0.55, p = 0.0098). Conclusions: Using the MC-ECG, the length of hospital stay in patients with STEMI was significantly reduced.

Trends in Post-Acute Care in US Nursing Homes: 2001-2017

OBJECTIVE

To describe recent trends in post-acute care provision within nursing homes, focusing specifically on nursing homes' degree of specialization in post-acute care.

DESIGN

Retrospective cohort study.

SETTING AND PARTICIPANTS

All US nursing homes between 2001 and 2017 and all fee-for-service Medicare admissions to nursing homes for post-acute care during that time.

METHODS

We measured post-acute care specialization as annual Medicare admissions per bed for each nursing home and examined changes in the distribution of specialization across nursing homes over the study period. We described the characteristics of nursing homes and the patients they serve based on degree of specialization.

RESULTS

The average number of Medicare admissions per bed increased from 1.2 in 2001 to 1.6 in 2017, a relative increase of 41%. This upward trend in the number of Medicare admissions per bed was largest among new nursing homes (those established after 2001), increasing 68% from 2001 to 2017. In contrast, nursing homes that eventually closed during the study period experienced no meaningful growth in the number of admissions per bed. Over time, the number of Medicare admissions per bed increased among highly specialized nursing homes. The number of Medicare admissions per bed grew by 66% at the 95th percentile and by 25% at the 99th percentile. Nursing homes delivering the most post-acute care were more likely to be for-profit or part of a chain, had higher staffing levels, and were less likely to admit patients who were Black, Hispanic, or dually enrolled in Medicare and Medicaid.

CONCLUSIONS AND IMPLICATIONS

Over the last 2 decades, post-acute care has become increasingly concentrated in a subset of nursing homes, which tend to be for-profit, part of a chain, and less likely to serve racial and ethnic minorities and persons on Medicaid. Although these nursing homes may benefit financially from higher Medicare payment, it may come at the expense of equitable access and patient care.

Mismatch of corneal specialists' expectations and keratoconus knowledge in general ophthalmologists - a prospective observational study in Switzerland

BACKGROUND

To assess whether Swiss general ophthalmologists have the minimal keratoconus knowledge that corneal specialists would expect them to have.

METHODS

Corneal specialists defined "minimal keratoconus knowledge" (MKK) with respect to definition, risk factors, symptoms and possible treatment options of keratoconus. A telephone interview survey was conducted among one hundred ophthalmologists (mean age 51.9 years (SD 9.5), 60 % male) from the German-speaking part of Switzerland. For each participant, years of work experience, number of keratoconus patients seen per year and access to a topography device were obtained. We calculated the proportion of MKK and examined in multivariate analyses whether ophthalmologists with access to topography and with greater work experience performed better than other groups.

RESULTS

No single ophthalmologist had MKK. The mean MKK was 52.0 %, and the range was 28.6-81.0 %. Per 10 years of working in private practice, the MKK decreased by 8.1 % points (95 % CI: -14.2, -2.00; p = 0.01). Only 24 % of participants correctly recalled the definition of keratoconus, 9 % all risk factors, 5 % all symptoms and 20 % all treatment modalities. The MKK values were not associated with the number of keratoconus patients seen per year and the availability of topography to diagnose keratoconus.

CONCLUSIONS

There is a substantial mismatch between corneal specialist' expectations and general ophthalmologists' knowledge about keratoconus. The low recall of symptoms and risk factors may explain why ophthalmologists diagnose relatively few cases of keratoconus, resulting in inefficient care delivery and delayed intervention.

Models of generalist and specialist care in smaller hospitals in England: a mixed-methods study

Background

The increasing number of older, complex patients who require emergency admission to hospital has prompted calls for better models of medical generalist care, especially for smaller hospitals, whose size constrains resources and staffing.

Objective

To investigate the strengths and weaknesses of the current models of medical generalism used in smaller hospitals from patient, professional and service perspectives.

Methods

The design was a mixed-methods study. Phase 1 was a scoping and mapping exercise to create a typology of models of care, which was then explored further through 11 case studies. Phase 2 created a classification using the Hospital Episode Statistics of acute medical ‘generalist’ and ‘specialist’ work and described differences in workload and explored the links between case mix, typology and length of stay and between case mix and skill mix. Phase 3 analysed the relationships between models of care and patient-level costs. Phase 4 examined the strengths and weaknesses of the models of care through focus groups, a discrete choice experiment and an exploration of the impact of typology on other outcomes.

Results

In total, 50 models of care were explored through 48 interviews. A typology was constructed around generalist versus specialist patterns of consultant working. Twenty-five models were deployed by 48 hospitals, and no more than four hospitals used any one model of care. From the patient perspective, analysis of Hospital Episode Statistics data of 1.9 million care episodes found that the differences in case mix between hospitals were relatively small, with 65–70% of episodes accounted for by 20 case types. The skill mix of hospital staff varied widely; there were no relationships with case mix. Patients exhibited a preference for specialist care in the discrete choice experiment but indicated in focus groups that overall hospital quality was more important. From a service perspective, qualitative work found that models of care were contingent on complex constellations of factors, including staffing, the local hospital environment and policy imperatives. Neither the model of care nor the case mix accounted for variability in the length of stay (no associations were significant at p < 0.05). No significant differences were found in the costs of the models. Professionally, the preferences of doctors for specialist versus generalist work depended on their experiences of providing care and were associated with a healthy organisational culture and a co-operative approach to managing emergency work. Concepts of medical generalism were found to be complex and difficult to define, with theoretical models differing markedly from models in action.

Limitations

Smaller hospitals in multisite trusts were excluded, potentially leading to sample bias. The rapidly changing nature of the models limited the analysis of typology against outcomes.

Conclusions

The case mix of smaller hospitals was dominated by patients with presentations amenable to generalist approaches to care; however, there was no evidence to support any particular pattern of consultant working. Matching hospital staff to better meet local need and the creation of more collaborative working environments appear more likely to improve care in smaller hospitals than changing models.

Future work

The exploration of the relationships between workforce, measures of hospital culture, models of care, costs and outcomes in both smaller and larger hospitals is urgently required to underpin service reforms.

Implementation and Impact of a Risk-Stratified Prostate Cancer Screening Algorithm as a Clinical Decision Support Tool in a Primary Care Network

BACKGROUND

Implementation methods of risk-stratified cancer screening guidance throughout a health care system remains understudied.

OBJECTIVE

Conduct a preliminary analysis of the implementation of a risk-stratified prostate cancer screening algorithm in a single health care system.

DESIGN

Comparison of men seen pre-implementation (2/1/2016-2/1/2017) vs. post-implementation (2/2/2017-2/21/2018).

PARTICIPANTS

Men, aged 40-75 years, without a history of prostate cancer, who were seen by a primary care provider.

INTERVENTIONS

The algorithm was integrated into two components in the electronic health record (EHR): in Health Maintenance as a personalized screening reminder and in tailored messages to providers that accompanied prostate-specific antigen (PSA) results.

MAIN MEASURES

Primary outcomes: percent of men who met screening algorithm criteria; percent of men with a PSA result. Logistic repeated measures mixed models were used to test for differences in the proportion of individuals that met screening criteria in the pre- and post-implementation periods with age, race, family history, and PSA level included as covariates.

KEY RESULTS

During the pre- and post-implementation periods, 49,053 and 49,980 men, respectively, were seen across 26 clinics (20.6% African American). The proportion of men who met screening algorithm criteria increased from 49.3% (pre-implementation) to 68.0% (post-implementation) (p < 0.001); this increase was observed across all races, age groups, and primary care clinics. Importantly, the percent of men who had a PSA did not change: 55.3% pre-implementation, 55.0% post-implementation. The adjusted odds of meeting algorithm-based screening was 6.5-times higher in the post-implementation period than in the pre-implementation period (95% confidence interval, 5.97 to 7.05).

CONCLUSIONS

In this preliminary analysis, following implementation of an EHR-based algorithm, we observed a rapid change in practice with an increase in screening in higher-risk groups balanced with a decrease in screening in low-risk groups. Future efforts will evaluate costs and downstream outcomes of this strategy.

Assessment of family and internal medicine physicians knowledge and practice of bronchial asthma at Riyadh city

Background:

The prevalence of bronchial asthma (BA) is increasing in the Kingdom of Saudi Arabia. The knowledge and adherence to guidelines by physicians can play a major role in controlling asthma.

Aim:

To assess the knowledge and practice of family medicine and internal medicine physicians about BAat King Saudi University medical city in Riyadh, Kingdom of Saudi Arabia.

Methodology:

A cross-sectional survey study was conducted. All family and internal medicine physicians at King Khalid University Hospital were included. A total of 180 physicians participated. The questionnaire was developed according to the Global Initiative for Asthma (GINA) guideline to assess the knowledge and practice of physicians towards bronchial asthma, included questions (diagnosis, severity classification, management, and referral).

Results:

All participated physicians knowledge and practice level about BAwaslow; the average scores were around 50%. The comparison between family and internal medicine physicians' knowledge shows insignificant differences. The only exception is the management part; family medicine physicians show better results than internal medicine physicians. The years of experience and higher qualification show significant improvement in the level of the knowledge scores.

Conclusion:

The knowledge of physicians about the diagnosis, assessment of severity, management, and referral of BA was unsatisfactory. We recommend an adoption of a special asthma clinic for teaching, supervising, and managing purposes assigned to an expert consultant.

Predictors of NOAC versus VKA use for stroke prevention in patients with newly diagnosed atrial fibrillation: Results from GARFIELD-AF

INTRODUCTION

A principal aim of the Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) was to document changes in treatment practice for patients with newly diagnosed atrial fibrillation during an era when non-vitamin K antagonist oral anticoagulants (NOACs) were becoming more widely adopted. In these analyses, the key factors which determined the choice between NOACs and vitamin K antagonists (VKAs) are explored.

METHODS

Logistic least absolute shrinkage and selection operator regression determined predictors of NOAC and VKA use. Data were collected from 24,137 patients who were initiated on AC ± antiplatelet (AP) therapy (NOAC [51.4%] or VKA [48.6%]) between April 2013 and August 2016.

RESULTS

The most significant predictors of AC therapy were country, enrolment year, care setting at diagnosis, AF type, concomitant AP, and kidney disease. Patients enrolled in emergency care or in the outpatient setting were more likely to receive a NOAC than those enrolled in hospital (OR 1.16 [95% CI: 1.04-1.30], OR: 1.15 [95% CI: 1.05-1.25], respectively). NOAC prescribing seemed to be favored in lower-risk groups, namely, patients with paroxysmal AF, normotensive patients, and those with moderate alcohol consumption, but also the elderly and patients with acute coronary syndrome. By contrast, VKAs were preferentially used in patients with permanent AF, moderate to severe kidney disease, heart failure, vascular disease, and diabetes and with concomitant AP.

CONCLUSION

GARFIELD-AF data highlight marked heterogeneity in stroke prevention strategies globally. Physicians are adopting an individualized approach to stroke prevention where NOACs are favored in patients with a lower stroke risk but also in the elderly and patients with acute coronary syndrome.

A comparison of one-year treatment utilization for shoulder osteoarthritis patients initiating care with non-orthopaedic physicians and orthopaedic specialists

Background

In this paper we investigate patients seeking care for a new diagnosis of shoulder osteoarthritis (OA) and the association between a patient’s initial physician specialty choice and one-year surgical and conservative treatment utilization.

Methods

Using retrospective data from a single large regional healthcare system, we identified 572 individuals with a new diagnosis of shoulder OA and identified the specialty of the physician which was listed as the performing physician on the index shoulder visit. We assessed treatment utilization in the year following the index shoulder visit for patients initiating care with a non-orthopaedic physician (NOP) or an orthopaedic specialist (OS). Descriptive statistics were calculated for each group and subsequent one-year surgical and conservative treatment utilization was compared between groups.

Results

Of the 572 patients included in the study, 474 (83%) received care from an OS on the date of their index shoulder visit, while 98 (17%) received care from a NOP. There were no differences in baseline patient age, gender, BMI or pain scores between groups. OS patients reported longer symptom duration and a higher rate of comorbid shoulder diagnoses. Patients initiating care with an OS on average received their first treatment much faster than patients initiating care with NOP (16.3 days [95% CI, 12.8, 19.7] vs. 32.3 days [95% CI, 21.0, 43.6], Z = 4.9, p < 0.01). Additionally, patients initiating care with an OS had higher odds of receiving surgery (OR = 2.65, 95% CI: 1.42, 4.95) in the year following their index shoulder visit.

Conclusions

Patients initiating care with an OS received treatment much faster and were treated with more invasive services over the year following their index shoulder visit. Future work should compare patient-reported outcomes across patient groups to assess whether more expensive and invasive treatments yield better outcomes for patients with shoulder OA.

Number of Board-Certified Cardiologists and Acute Myocardial Infarction-Related Mortality in Japan - JROAD and JROAD-DPC Registry Analysis

BACKGROUND

The appropriate number of board-certified cardiologists (BCC) for the treatment of acute myocardial infarction (AMI) has not been thoroughly examined in Japan. This study investigated whether the number of BCC/50 cardiovascular beds affects acute outcome in AMI treatment. Methods and Results: Data on 751 board-certified teaching hospitals and 63,603 patients with AMI were obtained from the Japanese Registry Of All cardiac and vascular Diseases (JROAD) and JROAD Diagnosis Procedure Combination (JROAD-DPC) databases between 1 April 2012 and 31 March 2014. The hospitals were categorized into 3 groups based on the median number of BCC/50 cardiovascular beds: first tertile, 5.0 (IQR, 4.0-5.7); second, 8.3 (IQR, 7.4-9.8); third, 15.3 (IQR, 12.5-22.7), and the patients with AMI admitted to the categorized hospitals were compared (first tertile, 12,002 patients; second, 23,930; third, 27,671). On hierarchical logistic modeling, the adjusted OR for 30-day mortality were 0.86 (95% CI: 0.74-1.00) for the second tertile and 0.75 (95% CI: 0.65-0.88) for the third tertile.

CONCLUSIONS

Patients with AMI admitted to hospitals with a large number of BCC/50 cardiovascular beds had a lower 30-day mortality rate. This tendency was independent of patient and hospital characteristics. This is the first study to provide new information on the association between the number of BCC and in-hospital AMI-related mortality in Japan.

Treatment for Rotator Cuff Tear Is Influenced by Demographics and Characteristics of the Area Where Patients Live

Background:

Atraumatic rotator cuff tear is a common orthopaedic complaint for people >60 years of age. Lack of evidence or consensus on appropriate treatment for this type of injury creates the potential for substantial discretion in treatment decisions. To our knowledge, no study has assessed the implications of this discretion on treatment patterns across the United States.

Methods:

All Medicare beneficiaries in the United States with a new magnetic resonance imaging (MRI)-confirmed atraumatic rotator cuff tear were identified with use of 2010 to 2012 Medicare administrative data and were categorized according to initial treatment (surgery, physical therapy, or watchful waiting). Treatment was modeled as a function of the clinical and demographic characteristics of each patient. Variation in treatment rates across hospital referral regions and the presence of area treatment signatures, representing the extent that treatment rates varied across hospital referral regions after controlling for patient characteristics, were assessed. Correlations between measures of area treatment signatures and measures of physician access in hospital referral regions were examined.

Results:

Among patients who were identified as having a new, symptomatic, MRI-confirmed atraumatic rotator cuff tear (n = 32,203), 19.8% were managed with initial surgery; 41.3%, with initial physical therapy; and 38.8%, with watchful waiting. Patients who were older, had more comorbidity, or were female, of non-white race, or dual-eligible for Medicaid were less likely to receive surgery (p < 0.0001). Black, dual-eligible females had 0.42-times (95% confidence interval [CI], 0.34 to 0.50) lower odds of surgery and 2.36-times (95% CI, 2.02 to 2.70) greater odds of watchful waiting. Covariate-adjusted odds of surgery varied dramatically across hospital referral regions; unadjusted surgery and physical therapy rates varied from 0% to 73% and from 6% to 74%, respectively. On average, patients in high-surgery areas were 62% more likely to receive surgery than the average patient with identical measured characteristics, and patients in low-surgery areas were half as likely to receive surgery than the average comparable patient. The supply of orthopaedic surgeons and the supply of physical therapists were associated with greater use of initial surgery and physical therapy, respectively.

Conclusions:

Patient characteristics had a significant influence on treatment for atraumatic rotator cuff tear but did not explain the wide-ranging variation in treatment rates across areas. Local-area physician supply and specialty mix were correlated with treatment, independent of the patient’s measured characteristics.

Factors affecting primary health-care physicians' emergency-related practice; Eastern Province, KSA

BACKGROUND

Being the first in-line care providers, primary health-care (PHC) physicians may encounter all forms of emergencies, ranging from minor complaints to life-threatening events. This wide variation of cases challenges the physicians to be competent in emergency medicine. Informative literature describing and assessing the factors affecting PHC physicians' emergency medical services (EMS)-related practice is deficient (nationally and internationally). The aim of this study is to assess PHC physicians' practice related to EMS, the factors affecting it, as well as their learning needs and preferred methods of continuous training in emergency medicine.

METHODS

All physicians working in the selected centers were invited to complete a self-administered questionnaire addressing their EMS-related practice. Moreover, physicians were invited to participate in face-to-face semi-structured interviews and focus group discussions.

RESULTS

The study revealed that 87.3% of physicians had a good diagnostic knowledge score while only 47.6% had a good management score. Nonetheless, 63.5% of physicians had a neutral attitude toward EMS. The most common reported emergencies encountered are bronchial asthma (86.51%), cut wounds (83.33%), and burns (76.19%). About 62% of participants reported that their greatest needs for further training were in cardiovascular and central nervous system emergency management, preferably by practical training in hospital emergency department (80%).

CONCLUSIONS

Dammam PHC physicians have a good knowledge, neutral attitude, and fair practice concerning the emergency cases encountered. The majority of physicians reported their need for further hands-on training in emergency medicine.

SETTINGS AND DESIGN

A cross-sectional, mixed methods study was conducted in 13 out of 26 PHC centers of Dammam, Saudi Arabia.

Attitudes of Non-Oncology Physicians Dealing with Cancer Patients. A Survey Based on Clinical Scenarios in Ancona Province, Central Italy

Aims and Background

With this study we attempted to determine to what extent recent acquisitions in clinical oncology had reached categories of physicians involved in the management of patients with cancer, namely general surgeons, internists and family doctors.

Methods

A questionnaire was prepared with scenarios based on the following clinical situations: Scenario A, Adjuvant therapy in colon cancer; Scenario B, Treatment of small-cell lung cancer; Scenario C, Adjuvant therapy in high-risk, node-negative breast cancer; Scenario D, Treatment of early stage breast cancer; Scenario E, Asymptomatic transient myelosuppression during chemotherapy. Questionnaires were mailed to 365 family doctors, 54 general surgeons and 61 internists of the Province of Ancona in central Italy.

Results

A total of 198 completed questionnaires were returned (41%). Respondents were 36.7% of family doctors, 54.1% of internists and 57.4% of surgeons. Less than half of respondents selected an adequate approach such as adjuvant chemotherapy for colon cancer and high-risk, node-negative breast cancer or chemotherapy as first-line treatment for small-cell lung cancer. Conservative surgery plus radiotherapy (QUART) for early stage breast cancer was indicated by 69% of respondents. Over three quarters of physicians would give treatment for asymptomatic transient chemotherapy-induced leukopenia. In most of the scenarios, significant differences were detected in the distribution of preferences according to category of physicians. Family doctors and young physicians (<40 years) generally performed worse than hospital-based physicians (general surgeons and internists) and older physicians.

Conclusions

Non-oncology physicians showed insufficient awareness of currently available knowledge in cancer treatment. Basic concepts in cancer management should be part of the professional knowledge of all medical doctors, and key advances in clinical oncology should spread outside the oncologic environment more promptly, with a wide circulation among all physicians who care for cancer patients.

What does physicians' clinical expertise contribute to oncologic decision-making? A qualitative interview study

BACKGROUND

Physicians' clinical expertise forms an exclusive body of competences, which helps them to find the appropriate diagnostics and treatment for each individual patient. Empirical evidence, however, suggests that there is an inverse relationship between the number of years in practice and the quality of care provided by a physician. Knowledge and adherence to professional standards (such as clinical guidelines) are often used as indicators in previous research.

METHODS

Semistructured interviews and the Q method were used for an explorative study on oncologists' views on the interplay between their own clinical expertise, intuition, and the external evidence incorporated in clinical guidelines. The interviews were audio recorded, transcribed ad verbatim, and analysed using qualitative content analysis.

RESULTS

Data analysis shows the complex character of clinical expertise with respect to experience, professional development, and intuition. An irreplaceable role is attributed to personal and bodily experience during the providing of care for a patient. Professional experience becomes important, particularly in those situations that lie out of the focus of "guideline medicine." Intuition is regarded as having a strong emotional component and helps for deciding which therapeutic option the patient can deal with.

CONCLUSIONS

Using measurable knowledge and adherence to standards as indicators does not account for the complexity of clinical expertise. Other factors, such as the importance of bodily experience and physicians' intuitive knowledge, must be considered, also with respect to the occurrence of treatment biases.

Endoscopic and Clinical Factors Affecting the Prognosis of Colorectal Endoscopic Submucosal Dissection-Related Perforation

Background/Aims

Although colorectal endoscopic submucosal dissection (ESD)-related perforation is not uncommon, the factors affecting clinical outcomes after perforation have not been investigated. This study was designed to investigate the factors influencing the clinical course of ESD-related colon perforation.

Methods

Forty-three patients with colorectal ESD-related perforation were evaluated. The perforations were classified as endoscopic or radiologic perforations. The patients’ medical records and endoscopic pictures were analyzed.

Results

The clinical outcomes were assessed by the duration of nil per os, intravenous antibiotics administration, and hospital stays, which were 2.7±1.5, 4.9±2.3, and 5.1±2.3 days, respectively. Multivariate analyses revealed that a larger tumor size, ESD failure, specific endoscopists, and abdominal pain were independently related to a poorer outcome. The time between perforation and clipping was 15.8±25.4 minutes in the endoscopic perforation group. The multivariate analysis of this group indicated that delayed clipping, specific endoscopists, and abdominal pain were independently associated with poorer outcomes.

Conclusions

Tumor size, ESD failure, abdominal pain, and the endoscopist were factors that affected the clinical outcomes of patients with colorectal ESD-related perforation. The time between the perforation and clipping was an additional factor influencing the clinical course of endoscopic perforation. Decreasing this time period may improve outcomes.

Current Trends for ST-segment Elevation Myocardial Infarction during the Past 5 Years in Rural Areas of China's Liaoning Province: A Multicenter Study

Background:

Since 2010, two versions of National Guidelines aimed at promoting the management of ST-segment elevation myocardial infarction (STEMI) have been formulated by the Chinese Society of Cardiology. However, little is known about the changes in clinical characteristics, management, and in-hospital outcomes in rural areas.

Methods:

In the present multicenter, cross-sectional study, participants were enrolled from rural hospitals located in Liaoning province in Northeast China, during two different periods (from June 2009 to June 2010 and from January 2015 to December 2015). Data collection was conducted using a standardized questionnaire. In total, 607 and 637 STEMI patients were recruited in the 2010 and 2015 cohorts, respectively.

Results:

STEMI patients in rural hospitals were older in the second group (63 years vs. 65 years, P = 0.039). We found increases in the prevalence of hypertension, prior percutaneous coronary intervention (PCI), and prior stroke. Over the past 5 years, the cost during hospitalization almost doubled. The proportion of STEMI patients who underwent emergency reperfusion had significantly increased from 42.34% to 54.47% (P < 0.0001). Concurrently, the proportion of primary PCI increased from 3.62% to 10.52% (P < 0.0001). The past 5 years have also seen marked increases in the use of guideline-recommended drugs and clinical examinations. However, in-hospital mortality and major adverse cardiac events did not significantly change over time (13.01% vs. 10.20%, P = 0.121; 13.34% vs. 13.66%, P = 0.872).

Conclusions:

Despite the great progress that has been made in guideline-recommended therapies, in-hospital outcomes among rural STEMI patients have not significantly improved. Therefore, there is still substantial room for improvement in the quality of care.

Acute coronary syndrome patients admitted to a cardiology vs non-cardiology service: variations in treatment & outcome

Background

Specialized cardiology services have contributed to reduced mortality in acute coronary syndromes (ACS).  We sought to evaluate the outcomes of ACS patients admitted to non-cardiology services in Southern Alberta.

Methods

Retrospective chart review performed on all troponin-positive patients in the Calgary Health Region identified those diagnosed with ACS by their attending team. Patients admitted to non-cardiology and cardiology services were compared, using linked data from the Alberta Provincial Project for Outcomes Assessment in Coronary Heart Disease (APPROACH) registry and the Strategic Clinical Network for Cardiovascular Health and Stroke.

Results

From January 1, 2007 to December 31, 2008, 2105 ACS patients were identified, with 1636 (77.7%) admitted to cardiology and 469 (22.3%) to non-cardiology services. Patients admitted to non-cardiology services were older, had more comorbidities, and rarely received cardiology consultation (5.1%). Cardiac catheterization was underutilized (5.1% vs 86.4% in cardiology patients (p < 0.0001)), as was evidence-based pharmacotherapy (p < 0.0001). Following adjustment for baseline comorbidities, 30-day through 4-year mortality was significantly higher on non-cardiology vs. cardiology services (49.1% vs. 11.0% respectively at 4-years, p < 0.0001).

Conclusion

In a large ACS population in the Calgary Health Region, 25% were admitted to non-cardiology services. These patients had worse outcomes, despite adjustment for baseline risk factor differences. Although many patients were appropriately admitted to non-cardiology services, the low use of investigations and secondary prevention medications may contribute to poorer patient outcome. Further research is required to identify process of care strategies to improve outcomes and lessen the burden of illness for patients and the health care system.

Evidence-Based Practice: Attitude and Knowledge of Social Workers across Geographic Regions

The objective of the author in this article was to examine possible differences in knowledge and attitudes toward evidence-based practice (EBP) among social workers across geographic regions. A random national sample of 180 NASW members was obtained from mail and Internet groups. MANOVA analysis was performed to determine possible differences in knowledge and attitudes toward EBP among these social workers. Findings suggest that knowledge and attitude toward EBP did not differ among these practitioners. Despite increasing efficacy and widespread knowledge of EBPs, there is little or no empirical evidence to support any differences in attitudes and knowledge of EBP among social workers across geographic regions.

Condition-specific Streaming versus an Acuity-based Model of Cardiovascular Care: A Historically-controlled Quality Improvement Study Evaluating the Association with Early Clinical Events

BACKGROUND

Ensuring optimal evidence translation is challenging when health-service design has not kept pace with developments in care. Differences in patient outcomes were evident when specific cardiac conditions were discordant with the subspecialty of the cardiologists managing their care. We prospectively explored the clinical and health service implications of a "condition-based" redesign in cardiac care delivery, rather than acuity-based, within a tertiary hospital.

METHODS

Prospective evaluation of a disease-specific streaming model of care compared to propensity-matched historical controls, among cardiac patients admitted to a tertiary hospital cardiology unit was undertaken. The outcome measures of 30-day death, and readmission for myocardial infarction, cardiac arrhythmia, and heart failure were explored.

RESULTS

In total, 2018 patients admitted subsequent to the implementation of the streaming model were compared with 1830 patients admitted prior. The median age was 68.9 years, and 39.5% were female. There was no significant difference in the overall proportion of patients admitted with an acute coronary syndrome, arrthythmia or heart failure, nor their Charlson index before and after streaming. Subsequent to the implementation, there was a reduction in the use of angiography (pre: 35.4% vs. post: 31.2%, p=0.007) and echocardiography (pre: 59.4% vs. post: 55.6%, p=0.007). A reduction in length of length-of-stay was observed in the entire cohort (pre: 2.7 (range: 1.2-5.0) days vs. post: 2.3 (range 1.0-4.5) days, p=0.0003). By 30 days, the propensity-adjusted hazard ratio for major adverse cardiac events and death or any cardiovascular admission was 0.76 (95% C.I. 0.59-0.97, p=0.026).

CONCLUSION

Cardiac service redesign that streams cardiac patients by presenting diagnosis into teams designed to treat that condition may provide capacity and productivity gains for health services striving to improve outcome and efficiency.

The effect of an evidence-based medicine curriculum on breast cancer knowledge and satisfaction of surgical residents

OBJECTIVE

The current study was performed to determine if evidence-based medicine (EBM) curriculum would affect education of surgical residents.

DESIGN

A 5-year prospective study was designed to determine if EBM curriculum could improve residents' satisfaction and understanding of breast cancer management during a breast surgical oncology rotation. During the first 2 years, 45 journal articles were used. During the subsequent 3 years, journal articles were not used. The proportion of patients seen in clinic was collected as an objective measure of the "effort" made by the resident. The final assessment was a 120-question examination.

SETTING

Maricopa Medical Center, Phoenix, AZ. Safety net institution with General Surgery residency program.

PARTICIPANTS

Postgraduate year 2 general surgery residents.

RESULTS

Over 5 years, 30 postgraduate year 2 residents were involved. Univariate analysis showed that female sex (p = 0.04), residents with peer-reviewed publications (p = 0.03), younger age (p = 0.04), American Board of Surgery in-service training examination score (p = 0.01), and clinical effort (p < 0.01) were associated with higher scores. Although residents taught using the journal articles scored 7 points higher on the final examination, this was not significant (p = 0.10). Multivariate analysis showed that American Board of Surgery in-service training examination score and clinic efficiency remained statistically significant. Residents who were taught using the EBM curriculum had significantly higher satisfaction (4.4 vs 3.5, p = 0.001) compared with those who did not go through the EBM curriculum.

CONCLUSIONS

The current study demonstrates that an EBM curriculum significantly improved resident satisfaction with the rotation. The EBM curriculum may improve residents' breast cancer knowledge. The most important predictor of resident performance was the effort of resident.

National trends in hospitalizations for sickle cell disease in the United States following the FDA approval of hydroxyurea, 1998-2008

BACKGROUND

Patients with sickle cell disease (SCD) can suffer frequent hospital admissions for painful vasoocclusive crises. Hydroxyurea was approved by the FDA in 1998 to decrease the morbidity of SCD, but nationwide hospitalizations for SCD in the United States since 1998 have not been evaluated. We hypothesized that the availability of hydroxyurea for SCD would be associated with a decrease in hospitalizations for SCD over time.

OBJECTIVE

To assess trends in hospitalization and length-of-stay in hospital for SCD in the United States, 1998 through 2008.

RESEARCH DESIGN

Retrospective cohort study of SCD-related hospital discharges in the Nationwide Inpatient Sample of US hospital discharges.

SUBJECTS

All discharges in the Nationwide Inpatient Sample associated with a principal diagnosis of SCD in blacks, 1998 through 2008.

MEASURES

Trends in hospitalization rates and average length-of-stay in hospital for SCD.

RESULTS

We found 216 (95% confidence interval, 173.3-258.7) SCD-related hospitalizations per 100,000 US blacks in 1998 and 178.4 (95% confidence interval, 144.2-212.5) in 2008, but no consistent yearly decrease, 1998 through 2008 (P=0.30). Conversely, the length-of-stay in hospital in 1998 was 5.38 days and in 2008 was 5.18 days, an absolute change of 0.2 days and a downward trend that was statistically significant.

CONCLUSIONS

Between 1998 and 2008, there was not a steady decrease in hospitalization rates for the population of SCD in the United States. On the contrary, there was a decline in length-of-stay in hospital over this time. Hydroxyurea underuse is well documented. Efforts to increase hydroxyurea use may help to reduce hospitalization rates.

Beliefs of Vocational Rehabilitation Counselors About Competitive Employment for People With Severe Mental Illness in Belgium

Vocational rehabilitation (VR) counselors do not always focus on competitive employment for people with severe mental illness (SMI). Based on the Theory of Planned Behavior (TPB), this study examines how three types of VR counselors (i.e., gatekeepers, case managers, and specialists) vary in their underlying beliefs about competitive employment. VR counselors ( N = 286) from Belgium completed an online TPB survey measuring behavioral, normative, control, and self-efficacy beliefs. Differences in beliefs were analyzed by one-way ANOVAs and post hoc comparisons using Bonferroni correction. Results indicate that counselors differ in their beliefs regarding competitive employment for people with SMI. Specialized counselors are stronger convinced that competitive employment results in latent benefits (e.g., increased integration and self-confidence). In contrast, gatekeepers consider income as the most recurrent and positive effect. The more specialized VR counselors are, the more often they perceive significant others valuing competitive employment and the more often they may comply with these norms. Finally, specialized counselors experience fewer barriers, more control, and more self-efficacy in dealing with problems compared with less specialized counselors. The differences in beliefs determining the focus on competitive employment may result in a lack of an integrated approach. Training, outcome feedback, and intersectoral communication can enhance consistency between different VR services.

The influence of surgeon age on distal radius fracture treatment in the United States: a population-based study

PURPOSE

This study attempted to determine the extent to which surgeon age influences treatment patterns for distal radius fractures (DRFs). We hypothesized that younger surgeons perform open reduction internal fixation (ORIF) for DRFs among elderly individuals more frequently than older surgeons, who employ a wider range of treatment modalities.

METHODS

We identified 61,314 Medicare beneficiaries who experienced DRFs and the 12,823 surgeons who performed ORIF, external fixation, pinning, or closed reduction on them during 2007. We examined the effect of surgeon age on DRF treatment pattern, controlling for patient characteristics and other surgeon factors using multinomial logistic regression. We then stratified our analysis by American Society for Surgery of the Hand membership to more closely examine the influence of surgeon specialization on the association between surgeon age and DRF treatment.

RESULTS

Surgeons aged 40 years and younger were more likely to perform ORIF and less likely to choose external fixation and percutaneous pinning to treat DRFs, compared with older surgeons. Surgeon specialization mitigated this relationship, and American Society for Surgery of the Hand members were more likely to choose ORIF compared with nonmembers. However, surgeon age remained a significant predictor of treatment choice after controlling for other factors and surgeon specialization.

CONCLUSIONS

Younger surgeons are more likely to perform ORIF for DRFs among Medicare beneficiaries over 65 years of age. Given the lack of evidence supporting any single treatment option for DRF, understanding the factors that drive dissemination of operative techniques may provide insight into treatment disparities within the Medicare population.

Hemodialysis patient outcomes: provider characteristics

BACKGROUND/AIMS

Physician characteristics are associated with differential performance on quality measures and patient outcomes in several medical fields. We aimed to determine whether characteristics of physicians who provide care to dialysis patients were associated with patient outcomes.

METHODS

This cohort study used United States Renal Data System data for patients who initiated in-center hemodialysis between October 1, 2003, and September 30, 2006 (n = 91,276). Patient characteristics were defined and physicians identified from Part B Medicare claims for outpatient dialysis services submitted during months 4-6 of hemodialysis. Physician characteristics were obtained from the American Medical Association Physician Master File. Associations of physician characteristics with 1-year patient mortality and first hospitalization were determined using Cox proportional hazards analysis; associations with quality of care (defined by influenza vaccination and waitlisting for kidney transplant) were determined using logistic regression.

RESULTS

Physician characteristics were not associated with patient mortality. After adjustment for patient and other provider characteristics, patients whose physicians had practiced longer or were in administrative, research, or teaching practices were more likely to be hospitalized; patients whose providers practiced in smaller metropolitan statistical areas (MSAs) were less likely. More years since training was associated with greater chance of waitlisting, and practicing in smaller MSAs with less chance. Graduation from a foreign medical school, practicing in smaller MSAs, and travelling farther from office to dialysis unit were associated with greater odds of influenza vaccination.

CONCLUSIONS

Several characteristics of physicians seeing incident outpatient hemodialysis patients were associated with hospitalization and quality of care, but none with mortality.

Rural-urban differences in acute myocardial infarction mortality: Evidence from Nebraska

AIMS

Acute myocardial infarction (AMI) remains a major cause of death and disability in the United States and worldwide. Despite the importance of surveillance and secondary prevention, the incidence of and mortality from AMI are not continuously monitored, and little is known about survival outcomes after 30 days of AMI hospitalization or associated risk factors, especially in the rural areas. The current study examines rural-urban differences in both in- and out-hospital survival outcomes for AMI patients.

METHODS

We performed a retrospective analysis using hospital discharge data in Nebraska for January 2005 to December 2009 and Nebraska death certificate records through October 2011. Multivariate logistic regression was used to estimate the rural-urban difference in 30-day mortality. A Cox proportional hazard model was used to predict out-of-hospital and overall survival rate.

RESULTS

In the 30-day mortality model, after controlling for age, comorbidities, and rehabilitation, patients in urban areas were less likely to die than patients in rural areas (odds ratio: 0.709, 95% confidence interval: 0.626-0.802). In the overall survival model, patients in urban areas had a lower hazard of AMI death (hazard ratio: 0.86, 95% confidence interval: 0.806-0.931) than patients in rural areas. Patients with a previous history of heart failure had a significantly higher likelihood of 30-day mortality, while atrial fibrillation, heart failure, and chronic kidney disease were associated with lower overall survival. Patients who attended at least 1 cardiac rehabilitation session had significantly lower 30-day and overall mortality (p < 0.0001).

CONCLUSIONS

This study confirms previous findings on rural-urban disparities in 30-day mortality following AMI hospitalization, and reports new findings on overall rural-urban mortality disparity. The study also found an association between cardiac rehabilitation and reduced mortality, a finding never before reported at the population level. Further efforts are needed to develop systems in rural hospitals and communities to ensure that AMI patients receive recommended care.

A comprehensive analysis of dyslipidaemia management in a large health care system

RATIONALE, AIMS AND OBJECTIVES

Dyslipidaemia is a cardiovascular risk factor, and national screening and treatment guidelines have been established, but achievement of these remains inadequate. Multidisciplinary approaches, such as the chronic care model, have been applied to other chronic diseases and likely would be applicable to the management of dyslipidaemia. We therefore aimed to comprehensively study the different components of a multidisciplinary management approach to dyslipidaemia in a large health care system for patients at a high risk for cardiovascular events.

METHODS

All patients at a Veterans Affairs Medical Center in the United States over 3 years with diabetes and/or coronary artery disease were included. Various clinical and demographic variables were collected and achievement of national cholesterol goals was determined. Univariate and multivariate analyses were conducted to determine the association of different health care variables with improved patient cholesterol guideline achievement.

RESULTS

There were 3559 patients in the study population and 51.0% had achieved national cholesterol goals. Multivariate analyses showed that patients who had achieved goals were more likely to have attended cardiology clinic [odds ratio (OR) = 1.6, 95% confidence interval (CI) = 1.3-2.01] and nutrition clinic (OR = 1.3, 95% CI = 1.04-1.7) and were more likely to have primary care providers who were nurse practitioners (OR = 1.6, 95% CI = 1.2-2.0), practicing full-time (OR = 1.8, 95% CI = 1.5-2.1) and at the main hospital-based clinics (OR = 1.5, 95% CI = 1.3-1.9).

CONCLUSIONS

Our study identifies different components of a multidisciplinary approach to management of dyslipidaemia that are efficacious and these results may help guide future investment in this area.

Performance measures of the specialty referral process: a systematic review of the literature

BACKGROUND

Performance of specialty referrals is coming under scrutiny, but a lack of identifiable measures impedes measurement efforts. The objective of this study was to systematically review the literature to identify published measures that assess specialty referrals.

METHODS

We performed a systematic review of the literature for measures of specialty referral. Searches were made of MEDLINE and HealthSTAR databases, references of eligible papers, and citations provided by content experts. Measures were eligible if they were published from January 1973 to June 2009, reported on validity and/or reliability of the measure, and were applicable to Organization for Economic Cooperation and Development healthcare systems. We classified measures according to a conceptual framework, which underwent content validation with an expert panel.

RESULTS

We identified 2,964 potentially eligible papers. After abstract and full-text review, we selected 214 papers containing 244 measures. Most measures were applied in adults (57%), assessed structural elements of the referral process (60%), and collected data via survey (62%). Measures were classified into non-mutually exclusive domains: need for specialty care (N = 14), referral initiation (N = 73), entry into specialty care (N = 53), coordination (N = 60), referral type (N = 3), clinical tasks (N = 19), resource use (N = 13), quality (N = 57), and outcomes (N = 9).

CONCLUSIONS

Published measures are available to assess the specialty referral process, although some domains are limited. Because many of these measures have been not been extensively validated in general populations, assess limited aspects of the referral process, and require new data collection, their applicability and preference in assessment of the specialty referral process is needed.

Is patient-perceived severity of a geriatric condition related to better quality of care?

BACKGROUND

Care for falls and urinary incontinence (UI) among older patients is inadequate. One possible explanation is that physicians provide less recommended care to patients who are not as concerned about their falls and UI.

OBJECTIVE

To test whether patient-reported severity for 2 geriatric conditions, falls, and UI, is associated with quality of care.

RESEARCH DESIGN

Prospective cohort study of elders with falls and/or fear of falling (n = 384) and UI (n = 163).

SUBJECTS

Participants in the Assessing Care of Vulnerable Elders-2 Study (2002-2003), which evaluated an intervention to improve the care for falls and UI among older (age, ≥ 75) ambulatory care patients with falls/fear of falling or UI.

MEASURES

Falls Efficacy Scale (FES) and the Incontinence Quality of Life surveys measured at baseline, quality of care measured by a 13-month medical record abstraction.

RESULTS

There was a small difference in falls quality scores across the range of FES, with greater patient-perceived falls severity associated with better odds of passing falls quality indicators (OR: 1.11 [95% CI: 1.02-1.21] per 10-point increment in FES). Greater patient-perceived UI severity (Incontinence Quality of Life score) was not associated with better quality of UI care.

CONCLUSIONS

Although older persons with greater patient-perceived falls severity receive modestly better quality of care, those with more distressing incontinence do not. For both conditions, however, even the most symptomatic patients received less than half of recommended care. Low patient-perceived severity of condition is not the basis of poor care for falls and UI.

The quality of care for adults with epilepsy: an initial glimpse using the QUIET measure

Background

We examined the quality of adult epilepsy care using the Quality Indicators in Epilepsy Treatment (QUIET) measure, and variations in quality based on the source of epilepsy care.

Methods

We identified 311 individuals with epilepsy diagnosis between 2004 and 2007 in a tertiary medical center in New England. We abstracted medical charts to identify the extent to which participants received quality indicator (QI) concordant care for individual QI's and the proportion of recommended care processes completed for different aspects of epilepsy care over a two year period. Finally, we compared the proportion of recommended care processes completed for those receiving care only in primary care, neurology clinics, or care shared between primary care and neurology providers.

Results

The mean proportion of concordant care by indicator was 55.6 (standard deviation = 31.5). Of the 1985 possible care processes, 877 (44.2%) were performed; care specific to women had the lowest concordance (37% vs. 42% [first seizure evaluation], 44% [initial epilepsy treatment], 45% [chronic care]). Individuals receiving shared care had more aspects of QI concordant care performed than did those receiving neurology care for initial treatment (53% vs. 43%; X² = 9.0; p = 0.01) and chronic epilepsy care (55% vs. 42%; X² = 30.2; p < 0.001).

Conclusions

Similar to most other chronic diseases, less than half of recommended care processes were performed. Further investigation is needed to understand whether a shared-care model enhances quality of care, and if so, how it leads to improvements in quality.

A method for estimating relative complexity of ambulatory care

PURPOSE

We wanted to demonstrate a method for calculating the relative complexity of ambulatory clinical encounters.

METHODS

Measures of complexity should reflect the complexity of the typical encounter and across encounters. If inputs represent the information transferred from the patient to the physician, then inputs include history, physical examination, testing, diagnoses, and patient demographics. Outputs include medications prescribed and other therapies used, including education and counseling, procedures performed, and disposition. The complexity of each input/output is defined as the mean input/output quantity per clinical encounter weighted by its inter-encounter diversity (range of possibilities used) and variability (visit-to-visit change). In complex systems, as the information in the input increases linearly, the complexity of the system increases exponentially. To assess the impact of the complexity of the encounter on the physician, we adjusted the estimated complexity by the duration-of-visit.

RESULTS

Using the 2000 NAMCS database, we calculated input and output complexities for 3 specialties. Construct validity was affirmed by comparing the relative rankings of complexity against relative rankings using other complexity-related measures. Although total relative complexity was similar for family medicine (44.04 +/- 0.0024 SE) and cardiology (42.78 +/- 0.0004 standard error [SE]), when adjusted for duration-of-visit, family medicine had a greater complexity density per hour (167.33 +/- 0.0095 SE) than either cardiology (125.4 +/- 0.0117 SE) or psychiatry (31.21 +/- 0.0027 SE).

CONCLUSIONS

This method estimates complexity based on the amount of care provided weighted by its diversity and variability. Such estimates could have broad use for interphysician comparisons as well as longitudinal applications.

Clipping Versus Coiling for Ruptured Intracranial Aneurysms

OBJECTIVE

Patients with intracranial aneurysms, both ruptured and unruptured, are frequently eligible for both open surgery (“clipping”) and endovascular repair (“coiling”). Although results of randomized trials have informed this decision, the actual choice of clipping or coiling for individual patients remains complex. At the 2007 Congress of Neurological Surgeons (CNS) Annual Meeting, a novel active learning process called Integrated Medical Learning (IML) was applied to education about this critical treatment choice.

METHODS

CNS members received an electronically distributed premeeting survey and educational materials about the clipping versus coiling decision and related topics. At the Annual Meeting, participants used handheld devices to choose clipping or coiling for treatment of individual aneurysms, both before and after expert opinion presentations. After the meeting, members who had answered premeeting surveys received a follow-up questionnaire.

RESULTS

In the premeeting poll, respondents with self-described specialties of “vascular,” Cerebrovascular Section members, surgeons with active cerebrovascular practices, and surgeons in practice for less than 20 years had higher levels of baseline knowledge of cerebrovascular literature (P &lt; .03). Surgeons' clinical volumes of clipping and coiling strongly influenced their vote for clipping or coiling for a hypothetical patient (P &lt; .01). At the meeting, in 6 of 8 cases of ruptured aneurysms the audience was split 75%:25% or closer to “clinical equipoise” (50:50 split). Surgeons with vascular specialty, academic surgeons, and residents were more likely to recommend clipping for individual cases (P &lt; .05). After experts' presentations, in 6 of 8 cases the audience opinion changed significantly. Vascular specialists and younger surgeons were less likely to change their opinion (P &lt; .03). The 2 cases with no shift in opinion were the most-clippable and most-coilable cases. Postmeeting surveys showed evidence of retained knowledge from the meeting, and respondents thought IML had been helpful.

CONCLUSIONS

Using IML, we were able to study baseline knowledge and practice patterns for an important cerebrovascular treatment decision. Evidence suggested that expert presentations were effective in changing audience opinion, at least in cases where preexisting opinion was close to clinical equipoise.

Self-reported and actual beta-blocker prescribing for heart failure patients: physician predictors

Background

Beta-blockers reduce mortality among patients with systolic heart failure (HF), yet primary care provider prescription rates remain low.

Objective

To examine the association between primary care physician characteristics and both self-reported and actual prescription of beta-blockers among patients with systolic HF.

Design

Cross-sectional survey with supplementary retrospective chart review.

Participants

Primary care providers at three New York City Veterans Affairs medical centers.

Measurements

Main outcomes were: 1) self-reported prescribing of beta-blockers, and 2) actual prescribing of beta-blockers among HF patients. Physician HF practice patterns and confidence levels, as well as socio-demographic and clinical characteristics, were also assessed.

Results

Sixty-nine of 101 physicians (68%) completed the survey examining self-reported prescribing of beta-blockers. Physicians who served as inpatient ward attendings self-reported significantly higher rates of beta-blocker prescribing among their HF patients when compared with physicians who did not attend (78% vs. 58%; p = 0.002), as did physicians who were very confident in managing HF patients when compared with physicians who were not (82% vs. 68%; p = 0.009). Fifty-one of these 69 surveyed physicians (74%) were successfully matched to 287 HF patients for whom beta-blocker prescribing data was available. Physicians with greater self-reported rates of prescribing beta-blockers were significantly more likely to actually prescribe beta-blockers (p = 0.02); however, no other physician characteristics were significantly associated with actual prescribing of beta-blockers among HF patients.

Conclusions

Physician teaching responsibilities and confidence levels were associated with self-reported beta-blocker prescribing among their HF patients. Educational efforts focused on improving confidence levels in HF care and increasing exposure to teaching may improve beta-blocker presciption in HF patients managed in primary care.

Depression and the cardiovascular system: increasing evidence of a link and therapeutic implications

This review explores the epidemiological evidence for the relationship between depression and cardiovascular disease from a mechanistic standpoint. It is important to examine the biological, behavioral and social mechanisms to improve outcomes for depressed cardiac patients. A number of plausible biobehavioral mechanisms linking depression and cardiovascular disease have been identified. Tricyclic antidepressants have various effects on the cardiovascular system, while selective serotonin reuptake inhibitors are not associated with adverse cardiac effects and should, therefore, be the preferred choice for the treatment of most patients with comorbid depression and cardiovascular disease.

Differences in initial benign prostatic hyperplasia management between primary care physicians and urologists

PURPOSE

The introduction of efficacious pharmacotherapies has effectively transformed benign prostatic hyperplasia into a chronic disease that requires ongoing medical care. With this transformation primary care physicians have become more involved in the management of benign prostatic hyperplasia. The impact of the increasing role of the primary care physician on the use of benign prostatic hyperplasia related health services remains unknown.

MATERIALS AND METHODS

We performed a retrospective cohort study using medical claims from a nonprofit managed care organization. Between 1997 and 2005 we identified incident cases of benign prostatic hyperplasia and the provider responsible for the initial care. We fitted logistic regression models to measure the association between subject receipt of an evaluative process and the treating physician specialty. Furthermore, we examined differences between primary care physicians and urologists with respect to the use of medical therapy.

RESULTS

Less than a third of incident cases received initial care from a urologist. Use of office based procedures and urodynamic tests was exclusive to urology. Urologists performed urinalysis testing and transrectal ultrasonography more frequently than primary care physicians (p <0.001). The odds of having a laboratory study doubled with treatment by a urologist (OR 2.03, 95% CI 1.51-2.74). Men seen by a urologist were also more likely to be prescribed a benign prostatic hyperplasia medication (p <0.001). Among those who received medical therapy, prescription of selective alpha-adrenergic blockers, 5alpha-reductase inhibitors and combination therapy was higher among urologists (p = 0.002).

CONCLUSIONS

On average, urologists had a higher intensity practice style for benign prostatic hyperplasia than primary care physicians. Further studies are needed to determine how these practice style differences relate to patient clinical outcomes.

Intervention to improve adherence to ACC/AHA recommended adjunctive medications for the management of patients with an acute myocardial infarction

BACKGROUND

The most recent published guidelines regarding management of patients surviving an acute myocardial infarction (AMI) advocate the administration of aspirin (ASA), beta blockers (BB), and angiotensin-converting enzyme inhibitors (ACEi) and discourages the use of calcium-channel blockers (CCB). Previous data collected in our region from the National Registry (NR) showed a dismal compliance with these guidelines. In an attempt to increase physician awareness and to optimize implementation of recommended guidelines, a cardiac and pharmacy steering committee was created.

METHODS

The pharmacist assigned to the project identified all patients admitted with an AMI using troponin-I and creatine kinase-MB (CK-MB) reports. The pharmacist then contacted physicians to make recommendations if an adjunctive medication was not prescribed for a patient with no apparent contraindications. Administration rates for ASA, BB, ACEi, and CCB were then assessed and compared with the previously obtained baseline data from the NR.

RESULTS

At admission, the use of ASA increased from 70 to 72%, BB from 45 to 72%, and ACEi from 12 to 44%. In terms of medications at discharge, ASA use increased from 74 to 88%, BB from 55 to 76%, and ACEi from 30 to 40%. In addition, the prescription rates for CCB at discharge decreased from 36 to 21%.

CONCLUSIONS

An interdisciplinary approach for disease management is an effective method for improving adherence to treatment guidelines simply with pharmacy intervention. The percentage of patients receiving the recommended adjunctive medications increased significantly. We propose that these guidelines should be periodically inserviced to physicians. Furthermore, patient counseling sessions should also be instituted to help reinforce the importance of compliance with the medications after discharge, as well as lipid management and smoking cessation.

Treatment of Suspected Cardiac Ischemia with Aspirin by Paramedics in an Urban Emergency Medical Services System

BACKGROUND

Aspirin (ASA) has unquestioned benefit to patients with cardiac ischemia. Previous studies indicate health care providers may not adequately treat patients experiencing cardiac ischemia with ASA.

OBJECTIVE

To determine the rate of ASA use for patients being treated for chest pain suggestive of cardiac ischemia in the prehospital setting.

METHODS

This was a retrospective study of paramedic encounters identified through billing records for all patients receiving the combination of an intravenous catheter, supplemental oxygen, and cardiac monitoring from November 2001 to January 2002. Prehospital medical records were reviewed in order to determine the proportion of patients with suspected cardiac ischemia who received ASA. The setting was a single prehospital emergency medical services system serving an urban population.

RESULTS

A total of 2,457 paramedic encounters were reviewed over a three-month period. Two hundred thirty-two patients were assessed as having cardiac ischemia, of whom 169 (73%) had no absolute or relative contraindication to ASA. Of the 169 patients, only 92 (54%) received ASA. Of the 99 patients, who received nitroglycerin for presumed cardiac ischemia and had no contraindication to receiving ASA, only 78 (79%) received ASA. Of the 453 patients complaining of nontraumatic chest pain and without a contraindication, 157 (35%) received ASA.

CONCLUSIONS

Paramedics do not use ASA optimally and may choose therapies with less proven benefit.

Differences in specialist consultations for cardiovascular disease by race, ethnicity, gender, insurance status, and site of primary care

BACKGROUND

Consultation with cardiologists may improve the quality of ambulatory care and reduce disparities for patients with heart disease. We assessed the use of cardiology consultations and the associated quality by race/ethnicity, gender, insurance status, and site of care.

METHODS AND RESULTS

In a retrospective cohort, we examined electronic records of 9761 adults with coronary artery disease or congestive heart failure (CHF) receiving primary care at practices affiliated with 2 academic medical centers during 2000 to 2005. During this period, 79.6% of patients with coronary artery disease and 90.3% of patients with CHF had a cardiology consultation. In multivariate analyses, women were less likely to receive a consultation than men for both conditions (coronary artery disease: hazard ratio, 0.89; 95% CI, 0.85 to 0.93; CHF: hazard ratio, 0.93; 95% CI, 0.87 to 0.99). Women also had 15% fewer follow-up consultations than men (P<0.001). Similarly, patients at community health centers were less likely to receive a consultation (coronary artery disease: hazard ratio, 0.79; 95% CI, 0.74 to 0.84; CHF: hazard ratio, 0.77; 95% CI: 0.71 to 0.84) and had 20% fewer follow-up consultations (P<0.001) relative to those at hospital-based practices. Black and Hispanic patients with CHF had 13% fewer follow-up consultations than white patients (P=0.01 and P=0.04, respectively). In adjusted analyses, consultation was associated with better processes of care compared with no consultation (P<0.001), particularly for women (P<0.001 for interaction between consultation and gender).

CONCLUSIONS

Among ambulatory patients with coronary artery disease or CHF, women and those at community health centers have less access to cardiologists. Consultation is associated with better quality of care and narrows the gender gap in quality.

A brief retrospective review of medical records comparing outcomes for inpatients treated via telehealth versus in-person protocols: is telehealth equally effective as in-person visits for treating neutropenic fever, bacterial pneumonia, and infected bacterial wounds?

The incidence of infectious diseases in the United States has been increasing since 1980. Re-emergent conditions, multidrug-resistant bacteria, newly identified infections, and bioterrorism have prompted public health surveillance and control initiatives, including the use of telehealth technology. Infectious diseases, such as West Nile Virus, pose a particular threat to rural areas, where access to infectious disease specialists (IDS) is limited. Initial, in-patient IDS consultations are reimbursed by Centers for Medicare & Medicaid Services for in-person and for telehealth services. Follow-up consultation and subsequent care visits are reimbursed when delivered via in-person care, but not reimbursed when delivered via telehealth. The purpose of this study is to investigate the efficacy of telehealth technology (interactive videoconferencing) in providing timely, efficient, and prudent infectious disease care for rural patients. We conducted a retrospective, comparative review of medical records (n = 107) from inpatients at a metropolitan hospital (n = 59) in a rural state who received in-person IDS treatment, with records from inpatients at nonmetropolitan, rural, and frontier hospitals (n = 48) in the same state who received telehealth IDS treatment. Outcome measures, including number of days hospitalized, number of days receiving intravenous antibiotic, survival, and transfer to another hospital, were compared for three commonly occurring infectious diseases: neutropenic fever, bacterial pneumonia, or bacterial wound infection. Patients treated via telehealth had fewer days on antibiotics and fewer days hospitalized than patients treated via in-person intervention. Survival rates did not differ significantly between groups, but were lower for telehealth patients. Fewer in-person patients required transfer to hospitals offering a higher level of care. Ninety percent of telehealth patients were able to remain at their local hospital for treatment. Results were statistically significant only for selected outcomes and conditions. IDS treatment for the conditions studied is equally effective when delivered via telehealth as when delivered via in-person methods.

A comparison of costs among patients with type 2 diabetes mellitus who initiated therapy with exenatide or insulin glargine

BACKGROUND

Exenatide (Byetta) and insulin glargine (Lantus) are antidiabetic agents that are typically used after lack of response to an oral antidiabetic agent(s). Although previous research has examined the impact of these medications on glycaemic control, there is little information about the relative costs associated with the medications.

OBJECTIVE

To compare costs among patients with type 2 diabetes mellitus treated with exenatide or insulin glargine from a US third-party payer perspective.

METHODS

Data from a large, national administrative claims database were used in this study. The intent-to-treat (ITT) cohort included adults who were diagnosed with type 2 diabetes and initiated therapy with either exenatide (n = 4090) or insulin glargine (n = 1660). In addition, included patients were required to have no diagnoses of type 1 diabetes, to have received at least two prescriptions for an oral antidiabetic agent in the 6 months prior to first use of either exenatide or insulin glargine and to have continuous insurance coverage from 6 months before, to 12 months after, initiation on ITT medication. Annual total medical costs and total diabetes-related medical costs, in $US, year 2007 values, were estimated using stepwise multivariate regressions. Major cost components were also examined using either stepwise multivariate regressions or a two-part model that controlled for the probability of using the service. Smearing estimates were used to transform estimated log costs into costs. The analysis controlled for the potential impact of patient demographics, general health, prior resource use, co-morbidities and complications, and timing of treatment initiation.

RESULTS

Compared with insulin glargine, initiation of exenatide was associated with significantly lower total direct medical costs ($US19,293 vs $US23,782; p < 0.0001), inpatient costs ($US4121 vs $US7532; p < 0.0001), outpatient costs ($US9501 vs $US12,885; p < 0.0001), emergency department (ED) costs ($US82 vs $US131; p < 0.0001), total diabetes-related medical costs ($US7833 vs $US8536; p < 0.0001), diabetes-related inpatient costs ($US2172 vs $US3538; p < 0.0001) and diabetes-related outpatient costs ($US2739 vs $US3249; p < 0.0001). Initiation of exenatide was associated with significantly higher total overall drug costs ($US6885 vs $US5936; p < 0.0001) and diabetes-related drug costs ($US3160 vs $US2422; p < 0.0001).

CONCLUSIONS

Compared with the use of insulin glargine, use of exenatide was associated with significantly lower annual total direct medical costs and significantly lower total diabetes-related medical costs, despite higher total drug costs and higher diabetes-related drug costs. In addition, exenatide was associated with significantly lower total inpatient, outpatient, ED, and diabetes-related inpatient and outpatient costs.

Physician attitudes toward end-stage heart failure: a national survey

BACKGROUND

Despite recent improvements in medical therapies, heart failure remains a prevalent condition that places significant burdens on providers, patients, and families. However, there is a paucity of data published describing physician beliefs about heart failure management, especially in its advanced stages.

METHODS

In order to better understand physician decision-making in end-stage heart failure, we used a stratified random sampling of physicians obtained from the Master File of the American Medical Association to survey cardiologists (n=600), geriatricians (n=250), and internists/family practitioners (n=600).

RESULTS

Response rate was 59.6% (highest among geriatricians). The vast majority (>90%) of respondents cited similarities between the clinical trajectory of end-stage heart failure and lung cancer or chronic obstructive pulmonary disease; however, only 15.7% stated that they could predict death at 6 months "most of the time" or "always." Inpatient volume was a predictor of confidence in predicting mortality (odds ratio=1.38, 95% confidence interval, 1.36-1.40). Less than one quarter of respondents formally measure quality of life. The experience with deactivation of implantable cardioverter defibrillators was limited: 59.8% of cardiologists, 88.0% of geriatricians, and 95.1% of internal medicine/family practice physicians have had 2 or fewer conversations with patients and families about this option.

CONCLUSIONS

Significant gaps in knowledge about and experience with end-stage heart failure exist among a large proportion of physicians. The growing prevalence and highly symptomatic nature of heart failure highlight the need to further evaluate and improve the way in which care is delivered to patients dying from the disease.

The diagnoses and co-morbidity encountered in the hospital practice of acute internal medicine

BACKGROUND

The exact medical conditions that every internist needs to know how to diagnose and treat have seldom been explicitly stated. This paper reports an analysis of the conditions, as identified by ICD9 coding, cared for by general internists working in a representative Irish hospital.

METHODS

In this observational study covering the period from February 17, 2000 to January 29, 2004, the ICD9 codes and mortality of 9214 consecutive patients admitted as acute medical emergencies were examined.

RESULTS

The mean number of ICD9 codes per patient was 4.0+/-1.8 (median 4.0 codes); 935 patients (10.1%) had one ICD9 code and 2972 (32.3%) had six ICD9 codes recorded at the time of discharge. As the number of ICD9 codes recorded increased, so did patient age, 30-day mortality and length of hospital stay. Thirty-four conditions were found to be associated with a statistically significant increased risk of 30-day mortality, and eight with a significantly reduced risk. Of the remaining conditions (i.e. those with neither an increased nor reduced risk of mortality), 32 were observed in 1% or more of all patients.

DISCUSSION

Nearly all of the clinical presentations encountered are encompassed within an average of four combinations of 74 conditions, 34 of which are associated with an increased risk of death.

Inpatient and follow-up cardiology care and mortality for acute coronary syndrome patients in the Veterans Health Administration

BACKGROUND

The impact of inpatient and follow-up cardiology care on patient outcomes after acute coronary syndrome (ACS) hospital discharge is unknown.

METHODS

This was a retrospective cohort study of all patients with ACS discharged from Veterans Health Administration facilities from 2003 to 2004. Patients were stratified into 2 categories of cardiology care: (1) inpatient and follow-up cardiology care within 60 days after discharge and (2) other levels of cardiology care (inpatient only, outpatient only, and neither inpatient nor outpatient). Multivariable regression assessed the association between inpatient and follow-up cardiology care with all-cause mortality, adjusting for demographics, comorbidities, hospital presentation and treatment variables, and clustering by site.

RESULTS

Of 4933 patients with ACS, the majority (71.6%) had inpatient and follow-up cardiology care. Patients with inpatient and follow-up cardiology care were more likely to have prior coronary disease and diabetes and to present with myocardial infarction (vs unstable angina). All-cause mortality was lower for patients with inpatient and follow-up cardiology care (18.8% vs 22.1%, P = .009). In multivariable analysis, patients with inpatient and follow-up cardiology care remained at lower mortality risk (hazard ratio 0.73, 95% CI 0.62-0.87) compared with patients with other levels of cardiology care. The findings were consistent when cardiology follow-up was defined as 30 or 90 days after hospital discharge.

CONCLUSIONS

Patients with inpatient and follow-up cardiology care have lower mortality risk after ACS. Future studies should identify mediators of this potential benefit and determine if interventions enhancing continuity of care in general, and continuity of subspecialty care in particular, after ACS will improve patient outcomes.
