Diagnostic error rates and associated factors for lower gastrointestinal perforation.

Lower gastrointestinal perforation is rare and challenging to diagnose in patients presenting with an acute abdomen. However, no study has examined the frequency and associated factors of diagnostic errors related to lower gastrointestinal perforation. This large-scale multicenter retrospective study investigated the frequency of diagnostic errors and identified the associated factors. Factors at the level of the patient, symptoms, situation, and physician were included in the analysis. Data were collected from nine institutions, between January 1, 2015 and December 31, 2019. Timely diagnosis was defined as diagnosis at the first visit in computed tomography (CT)-capable facilities or referral to an appropriate medical institution immediately following the first visit to a non-CT-capable facility. Cases not meeting this definition were defined as diagnostic errors that resulted in delayed diagnosis. Of the 439 cases of lower gastrointestinal perforation identified, delayed diagnosis occurred in 138 cases (31.4%). Multivariate logistic regression analysis revealed a significant association between examination by a non-generalist and delayed diagnosis. Other factors showing a tendency with delayed diagnosis included presence of fever, absence of abdominal tenderness, and unavailability of urgent radiology reports. Initial misdiagnoses were mainly gastroenteritis, constipation, and small bowel obstruction. In conclusion, diagnostic errors occurred in about one-third of patients with a lower gastrointestinal perforation.

Clinician Specialty, Access to Care, and Outcomes Among Patients with Peripheral Artery Disease.

BACKGROUND: Understanding the relationship between patterns of peripheral artery disease and outcomes is an essential step toward improving care and outcomes. We hypothesized that clinician specialty would be associated with occurrence of major adverse vascular events (MAVE). METHODS: Patients with at least 1 peripheral artery disease-related encounter in our health system and fee-for-service Medicare were divided into groups based on the specialty of the clinician (ie, cardiologist, surgeon, podiatrist, primary care, or other) providing a plurality of peripheral artery disease-coded care in the year prior to index encounter. The primary outcome was MAVE (a composite of all-cause mortality, myocardial infarction, stroke, lower extremity revascularization, and lower extremity amputation). RESULTS: The cohort included 1768 patients, of whom 30.0% were Black, 23.9% were Medicaid dual-enrollment eligible, and 31.1% lived in rural areas. Patients receiving a plurality of their care from podiatrists had the highest 1-year rates of MAVE (34.4%, P <.001), hospitalization (65.9%, P <.001), and amputations (22.6%, P <.001). Clinician specialty was not associated with outcomes after adjustment. Patients who were Medicaid dual-eligible had higher adjusted risks of mortality (adjusted hazard ratio [HRadj] 1.54, 95% confidence interval [CI] 1.11-2.14) and all-cause hospitalization (HRadj 1.20, 95% CI 1.03-1.40) and patients who were Black had a higher adjusted risk of amputation (HRadj 1.49, 95% CI 1.03-2.15). CONCLUSIONS: Clinician specialty was not associated with worse outcomes after adjustment, but certain socioeconomic factors were. The effects of clinician specialty and socioeconomic status were likely attenuated by the fact that all patients in this study had health insurance; these analyses require confirmation in a more representative cohort.

Herbal medicines from the industry in the unified health system: challenge faced by medical professionals

Abstract The World Health Organization recognized the use of herbal medicines as a therapeutic resource and its application in the primary attention to heath. The begin of this expansion was in 2006, with the National Policy on Integrative and Complementary practices of the Unified Health System (SUS). This research aimed to evaluate the questionnaires applied to doctors, who may have prescribed industrialized herbal medicines and to identify the difficulties involved with the implementation of this therapy as an integrative and complementary practice. It is a quantitative, observational and transversal study conducted in the municipality of Pinhais/Brazil. The questionnaire applied had as themes the experience of personal use of industrialized herbal medicines, improvement after their use. Forty-four individuals from four different nationalities: Brazilian (88.64%), Cuban (6.82%), Mexican (2.27%) and Argentinian (2.27%), ages between 25 and 69 years, mainly male sex (54.55%) answered the questionnaire. According to the study, the doctors consider herbal medicines an alternative to the conventional treatment and these medical professionals have already prescribed some industrialized herbal medications. Despite the difficulties faced by medical doctors with the prescription of herbs, it is possible to define strategies to assist these professionals, such as the incentive the actions by the governments.

Incidence of Medication Errors in King Fahad Hospital Madina Saudi Arabia

Abstract This study aimed to evaluate the incidence of medication errors over a period of one year in King Fahad Hospital Madina Saudi Arabia. This retrospective, cross-sectional study was conducted over a period of one year from 2018 January to 2018 December using patient's records. King Fahad Hospital in Madina was selected for the study center. Data collected include the number and types of errors, severity, location of errors, errors by profession, and errors occurred in the medical wards. Statistical analysis was carried out using statistical package for social science version22. A total of twenty- six hundred and fifty-eight medication errors were reported during the study period. Among the reports 2567(96.5%) of the errors were due to near misses, followed by transcribing errors 1597(60%), ordering errors 928(34.9%), duplicative therapy 765(28.7%), wrong dose 454(%). The most common procedures involve medication errors were wrong documentation 442(16.6%), duration 168(6.3%) wrong quantity 162(6.4%). Majority of the medication errors were contributed by physicians (99.2%) and 0.7% of them were due to the pharmacist. In conclusion study findings reported that yet some kind of medication errors has been under reported and it was common in most hospital, further studies with intervention programs needed to control the incidence of medication errors in a Saudi hospital

Collaborative attitudes between pharmacists and physicians in Brazil

Abstract Pharmacist-physician collaboration is a strategy for optimizing patient care and improving health outcomes. Nevertheless, there is a lack of information in Brazil about collaborative practices among these professionals. The aim of this study was to measure collaborative attitude of pharmacists and physicians who were working together in a teaching hospital. A cross-sectional study was conducted from June 2018 to January 2019 with pharmacists and physicians working in a teaching hospital in Northeastern Brazil. These professionals were invited to provide responses to the Brazilian version of the "Scale of Attitudes Towards Pharmacist-Physician Collaboration" (SATP2C); their scores ranged between 16 and 64 points. The software Epi Info TM (version 3.5.4) was used for data analysis, and data were expressed in means. Forty-four professionals participated in this study. The mean age was 33.5 (DP = 7.1) years. More than half of participants were male (n = 25, 56.8%). The means from the SATP2C for pharmacists and physicians were 54.20 and 50.91, respectively, indicating good collaborative attitudes. There was no statistical difference between the mean scores of pharmacists and physicians. Participants showed a predisposition for collaborative teamwork. Future studies should focus on understanding the process by which collaboration translates into clinical practice

HIV Pre-exposure Prophylaxis (PrEP): Knowledge, attitudes and counseling practices among physicians in Germany - A cross-sectional survey.

BACKGROUND: German statutory health insurance began covering the costs associated with HIV PrEP in September 2019; however, to bill for PrEP services, physicians in Germany must either be certified as HIV-specialists according to a nationwide quality assurance agreement, or, if they are non-HIV-specialists, have completed substantial further training in HIV/PrEP care. Given the insufficient implementation of PrEP, the aim of our study was to explore the potential to increase the number of non-HIV-specialists providing PrEP-related services. METHODS: We conducted an anonymous survey among a random sample of internists, general practitioners, dermatologists and urologists throughout Germany using a self-developed questionnaire. We calculated a knowledge score and an attitudes score from individual items in these two domains. Both scores ranged from 0-20, with high values representing good knowledge or positive attitudes. We also asked participants about the proportion of PrEP advice they provided proactively to men who have sex with men (MSM) and trans-persons who met the criteria to be offered PrEP. RESULTS: 154 physicians completed the questionnaire. Self-assessed knowledge among HIV-specialists was greater than among non-HIV-specialists [Median knowledge score: 20.0 (IQR = 0.0) vs. 4.0 (IQR = 11.0), p<0.001]. Likewise, attitudes towards PrEP were more positive among HIV-specialists than non-HIV-specialists [Median attitudes score: 18.0 (IQR = 3.0) vs. 13.0 (IQR = 5.25), p<0.001]. The proportion of proactive advice on PrEP provided to at-risk MSM and trans-persons by HIV-specialists [Median: 30.0% (IQR = 63.5%)] was higher than that provided by non-HIV-specialists [Median: 0.0% (IQR = 11.3%), p<0.001]. However, the results of our multiple regression suggest the only independent predictor of proactive PrEP advice was the knowledge score, and not whether physicians were HIV-specialists or non-HIV-specialists. CONCLUSIONS: These findings point to opportunities to improve PrEP implementation in individuals at risk of acquiring HIV. Targeted training, particularly for non-HIV-specialists, and the provision of patient-centered information material could help improve care, especially in rural areas.

SUDEP classification: Discordances between forensic investigators and epileptologists.

We compared sudden unexpected death in epilepsy (SUDEP) diagnosis rates between North American SUDEP Registry (NASR) epileptologists and original death investigators, to determine degree and causes of discordance. In 220 SUDEP cases with post-mortem examination, we recorded the epileptologist adjudications and medical examiner- and coroner- (ME/C) listed causes of death (CODs). COD diagnosis concordance decreased with NASR's uncertainty in the SUDEP diagnosis: highest for Definite SUDEP (84%, n = 158), lower in Definite Plus (50%, n = 36), and lowest in Possible (0%, n = 18). Rates of psychiatric comorbidity, substance abuse, and toxicology findings for drugs of abuse were all higher in discordant cases than concordant cases. Possible SUDEP cases, an understudied group, were significantly older, and had higher rates of cardiac, drug, or toxicology findings than more certain SUDEP cases. With a potentially contributing or competing COD, ME/Cs favored non-epilepsy-related diagnoses, suggesting a bias toward listing CODs with structural or toxicological findings; SUDEP has no pathognomonic features. A history of epilepsy should always be listed on death certificates and autopsy reports. Even without an alternate COD, ME/Cs infrequently classified COD as "SUDEP." Improved collaboration and communication between epilepsy and ME/C communities improve diagnostic accuracy, as well as bereavement and research opportunities.

Definitions of Physician Certification Used in the North American Literature: A Scoping Review.

INTRODUCTION: The authors sought to identify how physician specialty certification is defined in the North American literature. METHODS: A rigorous, established six-stage scoping review framework was used to identify the North American certification literature published between January 2006 and May 2016 relating to physician specialty certification. Data were abstracted using a charting form developed by the study team. Quantitative summary data and qualitative thematic analysis of the purpose of certification were derived from the extracted data. RESULTS: A two stage screening process identified 88 articles that met predefined criteria. Only 14 of the 88 articles (16%) contained a referenced purpose of certification. Eighteen definitions were identified from these articles. Definitional concepts included lifelong learning and continuous professional development, assessment of competence and performance, performance improvement, public accountability, and professional standing. DISCUSSION: Most articles identified in this scoping review did not define certification or describe its purpose or intent. Future studies should provide a definition of certification to further scholarly examination of its intent and effects and inform its further evolution.

Opioid prescribing patterns among medical providers in the United States, 2003-17: retrospective, observational study.

OBJECTIVE: To examine the distribution and patterns of opioid prescribing in the United States. DESIGN: Retrospective, observational study. SETTING: National private insurer covering all 50 US states and Washington DC. PARTICIPANTS: An annual average of 669 495 providers prescribing 8.9 million opioid prescriptions to 3.9 million patients from 2003 through 2017. MAIN OUTCOME MEASURES: Standardized doses of opioids in morphine milligram equivalents (MMEs) and number of opioid prescriptions. RESULTS: In 2017, the top 1% of providers accounted for 49% of all opioid doses and 27% of all opioid prescriptions. In absolute terms, the top 1% of providers prescribed an average of 748 000 MMEs-nearly 1000 times more than the middle 1%. At least half of all providers in the top 1% in one year were also in the top 1% in adjacent years. More than two fifths of all prescriptions written by the top 1% of providers were for more than 50 MMEs a day and over four fifths were for longer than seven days. In contrast, prescriptions written by the bottom 99% of providers were below these thresholds, with 86% of prescriptions for less than 50 MMEs a day and 71% for fewer than seven days. Providers prescribing high amounts of opioids and patients receiving high amounts of opioids persisted over time, with over half of both appearing in adjacent years. CONCLUSIONS: Most prescriptions written by the majority of providers are under the recommended thresholds, suggesting that most US providers are careful in their prescribing. Interventions focusing on this group of providers are unlikely to effect beneficial change and could induce unnecessary burden. A large proportion of providers have established relationships with their patients over multiple years. Interventions to reduce inappropriate opioid prescribing should be focused on improving patient care, management of patients with complex pain, and reducing comorbidities rather than seeking to enforce a threshold for prescribing.

A Structured Compensation Plan Results in Equitable Physician Compensation: A Single-Center Analysis.

OBJECTIVE: To assess adherence to and individual or systematic deviations from predicted physician compensation by gender or race/ethnicity at a large academic medical center that uses a salary-only structured compensation model incorporating national benchmarks and clear standardized pay steps and increments. PARTICIPANTS AND METHODS: All permanent staff physicians employed at Mayo Clinic medical practices in Minnesota, Arizona, and Florida who served in clinical roles as of January 2017. Each physician's pay, demographics, specialty, full-time equivalent status, benchmark pay for the specialty, leadership role(s), and other factors that may influence compensation within the plan were collected and analyzed. For each individual, the natural log of pay was used to determine predicted pay and 95% CI based on the structured compensation plan, compared with their actual salary. RESULTS: Among 2845 physicians (861 women, 722 nonwhites), pay equity was affirmed in 96% (n=2730). Of the 80 physicians (2.8%) with higher and 35 (1.2%) with lower than predicted pay, there was no interaction with gender or race/ethnicity. More men (31.4%; 623 of 1984) than women (15.9%; 137 of 861) held or had held a compensable leadership position. More men (34.7%; 688 of 1984) than women (20.5%; 177 of 861) were represented in the most highly compensated specialties. CONCLUSION: A structured compensation model was successfully applied to all physicians at a multisite large academic medical system and resulted in pay equity. However, achieving overall gender pay equality will only be fully realized when women achieve parity in the ranks of the most highly compensated specialties and in leadership roles.

Plantar fasciitis in physicians and nurses: a nationwide population-based study.

Physicians and nurses in Taiwan have heavy workload and long working hours, which may contribute to plantar fasciitis. However, this issue is unclear, and therefore, we conducted this study to delineate it. We conducted a nationwide population-based study by identifying 26,024 physicians and 127,455 nurses and an identical number of subjects for comparison (general population) via the National Health Insurance Research Database. The risk of plantar fasciitis between 2006 and 2012 was compared between physicians and general population, between nurses and general population, and between physicians and nurses. We also compared the risk of plantar fasciitis among physician subgroups. Physicians and nurses had a period prevalence of plantar fasciitis of 8.14% and 13.11% during the 7-yr period, respectively. The risk of plantar fasciitis was lower among physicians (odds ratio [OR]: 0.660; 95% confidence interval [CI]: 0.622-0.699) but higher among nurses (OR: 1.035; 95% CI: 1.011-1.059) compared with that in the general population. Nurses also had a higher risk than the physicians after adjusting for age and sex (adjusted odds ratio [AOR]: 1.541; 95% CI: 1.399-1.701). Physician subspecialties of orthopedics and physical medicine and rehabilitation showed a higher risk. Female physicians had a higher risk of plantar fasciitis than male physicians. This study showed that nurses, physician specialties of orthopedics and physical medicine and rehabilitation, and female physicians had a higher risk of plantar fasciitis. Improvement of the occupational environment and health promotion are suggested for these populations.

Approaches for identifying U.S. medicare fraud in provider claims data.

Quality and affordable healthcare is an important aspect in people's lives, particularly as they age. The rising elderly population in the United States (U.S.), with increasing number of chronic diseases, implies continuing healthcare later in life and the need for programs, such as U.S. Medicare, to help with associated medical expenses. Unfortunately, due to healthcare fraud, these programs are being adversely affected draining resources and reducing quality and accessibility of necessary healthcare services. The detection of fraud is critical in being able to identify and, subsequently, stop these perpetrators. The application of machine learning methods and data mining strategies can be leveraged to improve current fraud detection processes and reduce the resources needed to find and investigate possible fraudulent activities. In this paper, we employ an approach to predict a physician's expected specialty based on the type and number of procedures performed. From this approach, we generate a baseline model, comparing Logistic Regression and Multinomial Naive Bayes, in order to test and assess several new approaches to improve the detection of U.S. Medicare Part B provider fraud. Our results indicate that our proposed improvement strategies (specialty grouping, class removal, and class isolation), applied to different medical specialties, have mixed results over the selected Logistic Regression baseline model's fraud detection performance. Through our work, we demonstrate that improvements to current detection methods can be effective in identifying potential fraud.

Association of Physician Characteristics With Perceptions and Experiences of Gender Equity in an Academic Internal Medicine Department.

Importance: The persistence of inequities that disadvantage women physicians remains empirically underexplained. Understanding the cultural factors that are associated with disparities in harassment, discrimination, remuneration, and career trajectory are critical to addressing inequities. Objectives: To explore how physicians perceive the climate for women physicians and compare perceptions and experiences of gender inequity among physicians based on characteristics including gender, faculty status, parental status, and years in practice. Design, Setting, and Participants: This sequential, explanatory, mixed-methods qualitative study used the Culture Conducive to Women's Academic Success (CCWAS; range 45-225, with higher scores indicating better perceived culture toward women), followed by individual semistructured interviews with physicians at the Department of Medicine of the University of Calgary. All 389 physician members of the Department of Medicine, including academic and clinical physicians and those of any gender, were invited to participate in the survey and interview phases. Main Outcomes and Measures: The culture within the department for women physicians was assessed using the CCWAS score. Scores were compared between respondents' gender and years in practice. Interviews with physicians were used to further explore findings from the CCWAS and to understand experiences and perceptions of gender disparities. Results: A total of 169 of 389 physicians completed the survey (response rate, 43.4%; 102 [59.9%] women; 65 [38.9%] men; and 2 [1.2%] who did not disclose gender); 28 participants (7.2%) elected to participate in an interview (22 [78.6%] women; 6 [21.4%] men). Women physicians perceived the culture of the department toward women as significantly worse than men physicians (median [interquartile range] CCWAS score, 137.0 [118.0-155.0] vs 164.5 [154.0-183.4]; P < .001). Physicians with more than 15 years in practice perceived the culture toward women as significantly more favorable than physicians with 15 years or less in practice (median [interquartile range] CCWAS score, 157.0 [138.8-181.3] vs 147.0 [127.5-164.3]; P = .02). Qualitative data demonstrated that experiences of junior women (ie, physicians who graduated medical school after 1996, when an equal number of men and women in medical school was achieved in Canada) and perceptions of senior men (ie, those who graduated before 1996) were most different; junior women reported high rates of discrimination and harassment, while senior men perceived that the Department of Medicine had achieved gender equity. Conclusions and Relevance: In this study, senior men physicians' perceptions of gender equity were different from lived experiences of gender inequity reported by junior women physicians. This demographic mismatch between perceptions and experiences of gender equity in medicine may explain the lack of action by leaders and decision-makers in medicine to mitigate disparities.

Association of Specialist Physician Payment Model With Visit Frequency, Quality, and Costs of Care for People With Chronic Disease.

Importance: Specialist physicians are key members of chronic care management teams; to date, however, little is known about the association between specialist payment models and outcomes for patients with chronic diseases. Objective: To examine the association of payment model with visit frequency, quality of care, and costs for patients with chronic diseases seen by specialists. Design, Setting, and Participants: A retrospective cohort study using propensity-score matching in patients seen by a specialist physician was conducted between April 1, 2011, and September 31, 2014. The study was completed on March 31, 2015, and data analysis was conducted from June 2017 to February 2018 and finalized in August 2019. In a population-based design, 109 839 adults with diabetes or chronic kidney disease newly referred to specialists were included. Because patients seen by independent salary-based and fee-for-service (FFS) specialists were significantly different in observed baseline characteristics, patients were matched 1:1 on demographic, illness, and physician characteristics. Exposures: Specialist physician payment model (salary-based or FFS). Main Outcomes and Measures: Follow-up outpatient visits, guideline-recommended care delivery, adverse events, and costs. Results: A total of 90 605 patients received care from FFS physicians and 19 234 received care from salary-based physicians. Before matching, the patients seen by salary-based physicians had more advanced chronic kidney disease (2630 of 14 414 [18.2%] vs 6627 of 54 489 [12.2%]), and a higher proportion had 5 or more comorbidities (5989 of 19 234 [31.3%] vs 23 326 of 90 605 [25.7%]). Propensity-score matching resulted in a cohort of 31 898 patients (15 949 FFS, 15 949 salary-based) seeing 489 specialists. In the matched cohort, patients were similar (mean [SD] age, 61.3 [18.2] years; 17 632 women [55.3%]; 29 251 residing in urban settings [91.7%]). Patients seen by salary-based specialists had a higher follow-up visit rate compared with those seen by FFS specialists (1.74 visits; 95% CI, 1.58-1.92 visits vs 1.54 visits; 95% CI, 1.41-1.68 visits), but the difference was not significant (rate ratio, 1.13; 95% CI, 0.99-1.28; P = .06). There was no statistical difference in guideline-recommended care delivery, hospital or emergency department visits for ambulatory care-sensitive conditions, or costs between patients seeing FFS and salary-based specialists. The median association of physician clustering with health care use and quality outcomes was consistently greater than the association with the physician payment, suggesting variation between physicians (eg, median rate ratio for follow-up outpatient visit rate was 1.74, which is greater than the rate ratio of 1.13). Conclusions and Relevance: Specialist physician payment does not appear to be associated with variation in visits, quality, and costs for outpatients with chronic diseases; however, there is variation in outcomes between physicians. This finding suggests the need to consider other strategies to reduce physician variation to improve the value of care and outcomes for people with chronic diseases.

The Influence of Physician Information on Patients' Choice of Physician in mHealth Services Using China's Chunyu Doctor App: Eye-Tracking and Questionnaire Study.

BACKGROUND: Mobile health (mHealth) is becoming more popular as a way of sharing medical information. For the patient, it saves time, reduces the need for travel, reduces the cost of searching for information, and brings medical services "to your fingertips." However, it also brings information overload and makes the patient's choice of physician more difficult. OBJECTIVE: This study aimed to identify the types of physician information that play a key role in patients' choice of physician and to explore the mechanism by which this information contributes to this choice. METHODS: Based on the stimulus-organism-response (SOR) model and online trust theory, we proposed a research model to explain the influence of physician information on patients' choice of physician. The model was based on cognitive trust and affective trust and considered the moderating role of patient expertise. Study 1 was an eye-tracking experiment (n=42) to identify key factors affecting patients' choice of physician. Study 2 was a questionnaire study (n=272); Partial Least Squares Structural Equation Modeling was used to validate the research model. RESULTS: The results of Study 1 revealed that seven types of physician information played a key role in patients' choice of physician. The results of Study 2 revealed that (1) physicians' profile photo information affected patients' choice of physician by positively influencing affective trust (P<.001); (2) physicians' nonprofile photo information affected patients' choice of physician by positively influencing cognitive trust (P<.001); (3) patient-generated information affected patients' choice of physician by positively affecting cognitive trust (P<.001) and affective trust (P<.001), and patient expertise played a positive moderating role on both (P=.04 and P=.01, respectively); and (4) cognitive trust and affective trust both positively affected patients' choice of physician, with affective trust playing a more significant role (P<.001 and P<.001, respectively). CONCLUSIONS: Seven types of physician information were mainly used by patients when choosing physicians offering mHealth services; trust played an important role in this choice. In addition, the level of patient expertise was an important variable in moderating the influence of physician information and patients' trust. This paper supports the theoretical basis of information selection and processing by patients. These findings can help guide app developers in the construction of medical apps and in the management of physician information in order to facilitate patients' choice of physician.
