Coronary computed tomography angiography versus invasive coronary angiography: medical staff perceptions and diagnostic interest in Gaza-Palestine.

BACKGROUND: Invasive coronary angiography (ICA) and coronary computed tomography angiography (CCTA) are used in the diagnosis of coronary artery disease (CAD). The medical benefits, as well as the ethical and logistical implications, should be explored, particularly in the scarcity of medical resources. We explore the perception of medical staff toward the interest of CCTA and ICA in diagnosis CAD to maximize the utility of both procedures. METHODS: A triangulated observational, analytical prospective cohort study carried out among patients suspected with CAD who underwent CCTA and ICA. The quantitative part included 381 patients (250 underwent ICA and 131 underwent CCTA). The qualitative part included a purposive sample of two radiologists, three cardiologists, and two medical imaging specialists. RESULTS: Low diagnostic yield of the ICA through 31.3% and 39.7% diagnosed without CAD and non-significant CAD, respectively. Risk factors such as the family history of heart disease, obesity, high cholesterol, and diabetes were with high frequency in the patients with significant CAD. The sensitivity, specificity, PPV, and NPV of CCTA technique was 94.74%, 94.23%, 92.31%, and 96.08% respectively. Cardiologist's perceptions focused on radiation concerns and difficulties for convincing patients to perform the CCTA procedure. Radiologists and medical imaging specialists focused on complete cooperation from the cardiologist to better preparation of patients to perform optimal CCTA procedures. CONCLUSION: Efficient diagnostic benefits of CCTA and overuse of ICA for stable CAD are documented. Clear diagnostic strategy with medical, ethical, and logistical issues should be considered when selecting the CCTA or ICA for diagnosis CAD.

[How did the private labs fit onto COVID-19 crisis?] / Comment les laboratoires de biologie médicale privés français se sont adaptés à la crise de la COVID-19 ?

Confronted with the COVID-19 crisis, healthcare professionals have had to tackle an epidemic crisis of a huge magnitude for which they were not prepared. Medical laboratories have been on the front line, from collecting samples to performing the analysis required to diagnose this new pathology. Responding to the needs and to the urgency of the situation, the authorities relied on the network of private laboratories. In France, private laboratory medicine represents 70% of overall activity, and with a network of more than 4,000 local laboratories, private laboratory medicine has been the cornerstone of the « screen-trace-isolate ¼ strategy. This article gives feedback from private laboratory medicine professionals, directly involved in the reorganization carried out at the pre-analytical, analytical and post-analytical stages, during the crisis from March to October 2020.

Determinants of improved data consistency across routine immunization data tools for health facilities in Kano State, Nigeria.

INTRODUCTION: in this study, determinants of improved data consistency for routine immunization information at health facilities was measured to identify associated factors. METHODS: between June and August 2015, 1055 HFs were visited across 44 Local Government Areas in Kano state. We assessed data consistency, frequency of supportive supervision visits, availability of trained staff and attendance to monthly LGA RI review meetings. We compared RI monthly summary forms (MSF) versus national health management information system summary form (NHMIS) and vaccine management form 1a (VM1a) versus HF vaccine utilization summary monthly summary (HFVUM) for consistency. Data consistency at HF was determined at <+10% between number of children reportedly immunized, and doses of vaccine opened using 3 antigens (BCG, Penta and Measles). Levels of discrepancy <10% were considered as good data consistency. Bivariate and multivariate analysis used to determine association. RESULTS: data Consistency was observed in 195 (18.5%) HFs between (MSF vs NHMIS) and 90 (8.5%) HFs between (VM1a vs HFVUM). Consistency between MSF vs NHMIS was associated with receiving one or more SS visits in the previous month (p=0.001), data collection tools availability (p=0.001), recent attendance to monthly LGA RI review meeting and availability of trained staff. Data consistency between VM1a form and the HF VU summary was associated with a recent documented SS visit (p=0.05) and availability of trained staff (p=0.05). CONCLUSION: low level of data consistency was observed in Kano. Enhanced SS visits and availability of trained staff are associated with improved data quality.

Minimum standards for practices offering assisted reproductive technologies: a committee opinion.

This document is designed to provide a framework for assisted reproductive technology (ART) programs that meet or exceed the requirements suggested by the Centers for Disease Control and Prevention (CDC) for certification of ART laboratories. This document replaces the document, "Revised Minimum Standards for Practices Offering Assisted Reproductive Technologies: A Committee Opinion," published in 2014.

[The interplay between isolation and precariousness, and hospitalization duration in French Guiana]. / Calcul de l'IP-DMS en Guyane : prendre en compte le poids réel de la précarité et de l'isolement.

BACKGROUND: French Guiana faces singular health challenges: poverty, isolation, structural lag, difficulties in attracting health professionals. Hospital stays exceed the recommended durations. The present study aimed to model the impact of precariousness and geographic isolation on the hospital duration performance indicator and to recalculate the indicator after incrementing severity by 1 unit when patients were socially precarious. METHODS: Cayenne hospital data for 2017 were used to model the hospital duration performance indicator (IP-DMS) using quantile regression to study the impact of geographic and social explanatory variables. This indicator was computed hypothesizing a 1 unit increment of severity for precarious patients and by excluding patients from isolated regions. RESULTS: Most excess hospitalization days were linked to precariousness: the sojourns of precarious patients represented 47% of activity but generated 71% of excess days in hospital. Quantile regression models showed that after adjustment for potential confounders, patients from western French Guiana and Eastern French Guiana, precarious patients and the interactions terms between residence location and precariousness were significantly associated with IP-DMS increases. Recalculating the IP-DMSafter exclusion of patients from the interior and after increasing severity by 1 notch if the patient was precarious led to IP-DMS levels close to 1. CONCLUSION: The results show the nonlinear relationship between the IP-DMS and geographical isolation, poverty, and their interaction. These contextual variables must be taken into account when choosing the target IP-DMS value for French Guiana, which conditions funding and number of hospital beds allowed in a context of rapid demographic growth.

Intensivists' Direct Management without Residents May Improve the Survival Rate Compared to High-Intensity Intensivist Staffing in Academic Intensive Care Units: Retrospective and Crossover Study Design.

BACKGROUND: Medical staff members are concentrated in the intensive care unit (ICU), and medical residents are essentially needed to operate the ICU. However, the recent trend has been to restrict resident working hours. This restriction may lead to a shortage of ICU staff, and there is a chance that regional academic hospitals will face running ICUs without residents in the near future. METHODS: We performed a retrospective observational study (intensivist crossover design) of medical patients who were transferred to two ICUs from general wards between September 2017 and February 2019 at one academic hospital. We compared the ICU outcomes according to the ICU type (ICU with resident management under high-intensity intensivist staffing vs. ICU with direct management by intensivists without residents). RESULTS: Of 314 enrolled patients, 70 were primarily managed by residents, and 244 were directly managed by intensivists. The latter patients showed better ICU mortality (29.9% vs. 42.9%, P = 0.042), lower cardiopulmonary resuscitation (CPR) (10.2% vs. 21.4%, P = 0.013), lower continuous renal replacement therapy (CRRT) (24.2% vs. 40.0%, P = 0.009), and more advanced care planning decisions before death (87.3% vs. 66.7%, P = 0.013) than the former patients. The better ICU mortality (hazard ratio, 1.641; P = 0.035), lower CPR (odds ratio [OR], 2.891; P = 0.009), lower CRRT (OR, 2.602; P = 0.005), and more advanced care planning decisions before death (OR, 4.978; P = 0.007) were also associated with intensivist direct management in the multivariate cox and logistic regression analysis. CONCLUSION: Intensivist direct management might be associated with better ICU outcomes than resident management under the supervision of an intensivist. Further large-scale prospective randomized trials are required to draw a definitive conclusion.

Sonologist's characteristics related to a higher quality in fetal nuchal translucency measured in primary antenatal care centers.

OBJECTIVE: To assess the quality of nuchal translucency (NT) measurements in primary care and the sonologist's characteristics related with a higher quality. METHODS: The median NT expressed in multiples of the median (MoM) was calculated for each sonologist of 14 participating antenatal primary care centers of the Catalan Institute of Health. A survey to the sonologists was used to establish variables related to higher-quality measurements. RESULTS: The median NT MoM obtained in 16 448 NT measurements, performed by 102 sonologists, was 0.94 MoM. NT underestimation was observed in 46% of the sonologists. Underestimation were less frequent among professionals who performed more than 230 ultrasounds per year (26% vs 53%;p = .022), those who completed the online Fetal Medicine Foundation (FMF) course (22% vs 54%; p = .021), and those who were subject to periodic audits (24% vs 56%; p = .021). Underestimation rate decreased from 60%, to 33% and 14% with the increase of the years of experience from less than 5 years, to 6 to 15 years and more than 15 years of experience, respectively (p = .029). CONCLUSIONS: Higher-quality measurements were demonstrated in sonologists who performed more ultrasounds per year, those with more years of scanning experience, those who completed the online FMF course, and those periodically audited.

[Staff and organizational requirements for pain services in hospitals : A recommendation from the German Society for Anaesthesiology and Intensive Care Medicine]. / Personelle und organisatorische Voraussetzungen für Schmerzdienste in Krankenhäusern : Empfehlung der Deutschen Gesellschaft für Anästhesiologie und Intensivmedizin e. V.

Although pain services have been established in many hospitals, there is considerable heterogeneity among them with respect to organization of service, staff and qualifications of staff, and treatment approaches.With this recommendation, the German Society for Anesthesiology and Intensive Care Medicine defines requirements for pain services in hospitals with respect to organizational standards and staff qualifications. The therapy offered by pain services supplements the treatment provided by the other departments involved, ensuring the high quality of specialized pain management in all areas of the hospital. Pain services shall oversee treatment with specialized analgesia techniques as well as the involvement of consultants, bringing together in-hospital pain medicine expertise in one service with availability 24 h and 7 days per week via a single contact. The medical head of the pain service shall be a qualified provider of pain medicine as defined by the German Medical Association and as a minimum should also have undergone additional training in basic psychosomatic medicine. Further members of the medical staff should possess the credentials of a medical specialist: non-medical staff should have completed continuing education in the treatment of pain. Minimal guidelines for personnel resources were defined: these included a specific time frame for first contacts (20 min) and follow-up (10 min) for specific analgesic techniques and for the involvement of consultants (first contact 45 min, follow-up 20 min), with additional time for travel, set-up, training and quality management. In addition to definition of the space and equipment needed, each service should draft its own budget, and this should be adequate and plannable. Written agreements between the disciplines and transparent documentation, including patient-reported outcomes, are recommended to ensure quality. The provision of specialized pain therapy should have high priority over all disciplines or departments.

Does an all-condition case management program for high-risk patients reduce health care utilization in medicaid and medicare beneficiaries with diabetes?

OBJECTIVE: To assess whether an all-condition case management program can improve health care utilization and clinical outcomes in patients with diabetes. RESEARCH DESIGN AND METHODS: 1342 patients with diabetes were enrolled in the Johns Hopkins Community Health Partnership (J-CHiP) Case Management program for high-risk patients with any chronic disease. We categorized participants into two intervention exposure categories based on the number of contacts with case manager (CM) and community health worker (CHW) per month: low contact (≤1 contact/month), and high contact (>1 contacts/month). The primary outcomes were rates of emergency department (ED) visits, hospitalizations, and 30-day hospital readmissions. RESULTS: In analyses adjusted for age, sex, race, risk score, and baseline health utilization rate, Medicaid participants in the high contact group had 42% (rate ratio (RR): 1.42; 95% CI: 1.08-1.86) and 64% (RR: 1.64; 95% CI: 1.08-2.48) higher risks for hospital admission and readmission, respectively, than the low contact group. Similar increases were seen in the Medicare participants with 20% (RR: 1.20; 95% 1.02-1.42) and 42% (RR:1.42; 95% 1.09-1.84) higher risks for admission and readmission, respectively. The associations were not statistically significant for ED visits. Subsidiary analysis of a subset with HbA1c available (n = 545) revealed a statistically significant decrease in HbA1c among Medicare participants (mean (SD): -0.17% (1.50%)), with a larger decrease in the high contact group (mean (SD): -0.23% (1.59%)). CONCLUSION: In an all-condition case management program for high-risk patients, the higher intensity of contacts with CHW and CM was not associated with a reduced health care utilization in adults with diabetes.

[Evaluation of the knowledge of intermittent preventive treatment during pregnancy (IPTp) with sulfadoxine-pyrimethamine in Ivory Coast]. / Évaluation de la connaissance du traitement préventif intermittent au cours de la grossesse (TPIg) par la sulfadoxine-pyriméthamine en Côte d'Ivoire.

In 2006, because of the chloroquine-resistance and following the World Health Organization (WHO) recommendations, Côte d'Ivoire adopted a new policy for the prevention of malaria during pregnancy by intermittent preventive treatment in pregnancy with sulfadoxine-pyrimethamine (IPTp-SP). However, its implementation remains limited. Objectives of this study were to evaluate the knowledge of the TPIp-SP regimen and prescribers opinion concerning this protocol. It was a knowledge attitude and pratices (KAP) cross-sectional descriptive study. We used a two-stage stratified sounding. The study took place in 12 health facilities in the health region of Abidjan 2 from march to august 2016 and involved 187 health professionals. We performed descriptive analysis, univariate and bivariate comparative analysis. The study found that half of the prescribers surveyed actually knew the ITPp program (SP - 3 doses - 2nd and 3rd trimesters). Knowledge was better among practitioners with more than 5 years of exercise (P=0.011) and at the level of first contact of health institution (P=0.001). Half of the prescribers were in favor of applying the protocol. The level of knowledge of prescribers has changed little in 2016 compared to 2008 for physicians (Pr (|Z|<|z|)=0.4861) or midwives Pr (|Z|<|z|)=0.4786). Prescribers remained faithful to the old 2-dose protocol. The opinion on the protocol was better in 2016 compared to 2008 Pr (Z

The impact of patient feedback on the medical performance of qualified doctors: a systematic review.

BACKGROUND: Patient feedback is considered integral to quality improvement and professional development. However, while popular across the educational continuum, evidence to support its efficacy in facilitating positive behaviour change in a postgraduate setting remains unclear. This review therefore aims to explore the evidence that supports, or refutes, the impact of patient feedback on the medical performance of qualified doctors. METHODS: Electronic databases PubMed, EMBASE, Medline and PsycINFO were systematically searched for studies assessing the impact of patient feedback on medical performance published in the English language between 2006-2016. Impact was defined as a measured change in behaviour using Barr's (2000) adaptation of Kirkpatrick's four level evaluation model. Papers were quality appraised, thematically analysed and synthesised using a narrative approach. RESULTS: From 1,269 initial studies, 20 articles were included (qualitative (n=8); observational (n=6); systematic review (n=3); mixed methodology (n=1); randomised control trial (n=1); and longitudinal (n=1) design). One article identified change at an organisational level (Kirkpatrick level 4); six reported a measured change in behaviour (Kirkpatrick level 3b); 12 identified self-reported change or intention to change (Kirkpatrick level 3a), and one identified knowledge or skill acquisition (Kirkpatrick level 2). No study identified a change at the highest level, an improvement in the health and wellbeing of patients. The main factors found to influence the impact of patient feedback were: specificity; perceived credibility; congruence with physician self-perceptions and performance expectations; presence of facilitation and reflection; and inclusion of narrative comments. The quality of feedback facilitation and local professional cultures also appeared integral to positive behaviour change. CONCLUSION: Patient feedback can have an impact on medical performance. However, actionable change is influenced by several contextual factors and cannot simply be guaranteed. Patient feedback is likely to be more influential if it is specific, collected through credible methods and contains narrative information. Data obtained should be fed back in a way that facilitates reflective discussion and encourages the formulation of actionable behaviour change. A supportive cultural understanding of patient feedback and its intended purpose is also essential for its effective use.

Absolute clinical skill decay in the medical, nursing and allied health professions: a scoping review protocol.

REVIEW QUESTIONS/OBJECTIVES: The objective of this scoping review is to examine and map absolute clinical skill decay in the medical, nursing and allied health professions and to map the range of approaches used to address decay of clinical skills in these professions.Specifically, the review questions are: which clinical skills, performed by which professional groups, are reported to be most susceptible to absolute clinical skill decay, and what approaches have been reported for addressing absolute clinical skill decay in the medical, nursing and allied health professions?In addressing the review questions, the following sub-questions will also be addressed:It is anticipated that this scoping review will inform further systematic review/s on the topic of addressing clinical skill decay in the medical, nursing and allied health professions, as well as identify gaps in the research knowledge base that will inform further primary research.

End of life care for people with dementia: The views of health professionals, social care service managers and frontline staff on key requirements for good practice.

BACKGROUND: Evidence consistently shows that people with advanced dementia experience suboptimal end of life care compared to those with cancer; with increased hospitalisation, inadequate pain control and fewer palliative care interventions. Understanding the views of those service managers and frontline staff who organise and provide care is crucial in order to develop better end of life care for people with dementia. METHODS AND FINDINGS: Qualitative interviews and focus groups were conducted from 2013 to 2015 with 33 service managers and 54 staff involved in frontline care, including doctors, nurses, nursing and care home managers, service development leads, senior managers/directors, care assistants and senior care assistants/team leads. All were audio recorded and transcribed verbatim. Participants represented a diverse range of service types and occupation. Transcripts were subject to coding and thematic analysis in data meetings. Analysis of the data led to the development of seven key themes: Recognising end of life (EOL) and tools to support end of life care (EOLC), Communicating with families about EOL, Collaborative working, Continuity of care, Ensuring comfort at EOL, Supporting families, Developing and supporting staff. Each is discussed in detail and comprise individual and collective views on approaches to good end of life care for people with dementia. CONCLUSIONS: The significant challenges of providing good end of life care for people with dementia requires that different forms of expertise should be recognised and used; including the skills and knowledge of care assistants. Successfully engaging with people with dementia and family members and helping them to recognise the dying trajectory requires a supportive integration of emotional and technical expertise. The study strengthens the existing evidence base in this area and will be used with a related set of studies (on the views of other stakeholders and observations and interviews conducted in four services) to develop an evidence-based intervention.

Interobserver agreement using Goldmann applanation tonometry and dynamic contour tonometry: comparing ophthalmologists, nurses and technicians.

PURPOSE: To compare agreement between ophthalmologists and non-ophthalmologists (nurses and ophthalmic technicians) when measuring the intraocular pressure (IOP) using Goldmann applanation tonometry (GAT) and Pascal dynamic contour tonometry (DCT). METHODS: Patients attending for their routine glaucoma outpatient appointment were invited to participate. IOP was measured in one eye by either two ophthalmologists (observer group 1), two non-ophthalmologists (observer group 2) or one ophthalmologist and one non-ophthalmologist (observer group 3). All were experienced in using GAT and some experienced in using the DCT. The order of tonometer and staff was randomised. Agreement was calculated by Bland-Altman analysis, with the mean difference and 95% limits of agreement (LoA) of measurements calculated for each observer group. RESULTS: One hundred eyes were measured within each observer group. The mean difference (95% LoA) in IOP measurements were GAT: group 1=-0.20 (4.9) mm Hg, group 2=0.6 (5.4) mm Hg and group 3=0.0 (3.7) mm Hg; DCT: group 1=0.8 (7.7) mm Hg, group 2=0.3 (4.2) and group 3=0.0 (5.2) mm Hg. The DCT consistently over-read the GAT for all observer groups. DISCUSSION/CONCLUSIONS: Ophthalmologists show good levels of agreement with each other when using GAT, while technicians/nursing staff show better agreement when using the DCT. The DCT may be a better tonometer to use if permanently delegating IOP measurements to non-ophthalmologists, but measurements cannot be interchanged with the GAT.

Surgical team composition has a major impact on effectiveness and costs in laparoscopic donor nephrectomy.

PURPOSE: Limited evidence exists that optimization of surgical team composition may improve effectiveness of laparoscopic donor nephrectomy (LDN). METHODS: A retrospective cohort study with 541 consecutive LDNs. From 2003 to 2012, surgical team composition was gradually optimized with regard to the surgeons' experience, proficient assistance and the use of fixed teams. RESULTS: Multivariable analysis showed that a surgical team with an experienced surgeon had a significantly shorter operation time (OT) (-18 min, 95% CI -28 to -9), less estimated blood loss (EBL) (-64 mL, 95% CI -108 to -19) and shorter length of stay (LOS) (-1 day, 95% CI -1.6 to 0). Proficient assistance was also independently associated with a shorter OT (-43 min, 95% CI -53 to -33) and reduced EBL (-58 mL, 95% CI -109 to -6), whereas those procedures performed by fixed teams were related to a shorter operation (-50 min, 95% CI -59 to -43) and warm ischemia time (-1.8, 95% CI -2.1 to -1.5), a reduced mean complication grade (-0.14 per patient, 95% CI -0.3 to -0.02) and a shorter LOS (-1.1 day, 95% CI -1.7 to -05). Health care costs for LDN by one staff surgeon with unproficient assistance were 7.707 Euro, whereas costs for LDN by two staff surgeons in fixed teams were 5.614 Euro. CONCLUSIONS: Surgical team composition has a major impact on variables that reflect the effectiveness of LDN from the donors' perspective. Health care costs are lower for LDNs performed by two experienced surgeons in fixed team composition. We advocate the use of two experienced surgeons in fixed team composition for LDN.

Substance abuse-specific knowledge transfer or loss? Treatment program turnover versus professional turnover among substance abuse clinicians.

This longitudinal study investigated the extent to which substance abuse (SA) clinician turnover is associated with SA-specific knowledge loss due to change in professions (professional turnover) versus SA-specific knowledge transfer due to movement from one SA clinical setting to another (treatment program turnover). For this study, clinicians had to have voluntarily left their current treatment program. Eligible clinicians completed a quantitative survey while employed and a qualitative post-employment exit interview 1 year later. Compared to those that exited the SA profession (n = 99), clinicians who changed treatment programs (n = 120) had greater SA-specific formal knowledge and were more likely to be personally in recovery. No differences were found between the two groups in terms of SA-specific practical knowledge.

A cross-sectional study showing differences in the clinical diagnosis of pelvic inflammatory disease according to the experience of clinicians: implications for training and audit.

OBJECTIVES: Pelvic inflammatory disease (PID) generates diagnostic difficulty even for experienced doctors. Junior doctors and nurses also assess women with symptoms suggestive of PID. We aimed to determine if and how PID diagnoses vary between clinicians with different experience levels. METHODS: Cross-sectional study conducted in U.K. sexual health clinic, nested within a Chlamydia trachomatis (CT), and Neisseria gonorrhoea diagnostic test accuracy study. Proportions and characteristics of women diagnosed clinically with PID by clinicians with varying experience were compared. Outcomes included demographics, presenting symptoms and signs and CT, and CT and/or gonococcal (GC) (CT/GC) positivity. RESULTS: In 3804 women assessed by 36 clinicians, rates of PID, CT and GC were 4.4%, 10.5%, and 2.5%, with no differences between experienced and inexperienced clinicians (p=0.84, p=0.13 and p=0.07, respectively). 63.7% of PID diagnosed by experienced clinicians met Centers for Disease Control and Prevention (CDC) key clinical criteria versus 41.2% by inexperienced; experienced versus inexperienced OR 2.51; 95% CI 1.16 to 5.40). Proportions of CT (CT/GC)-positive PID increased with experience (5.9% (11.8%) to 31.9% (34.1%)); experienced versus inexperienced (OR 3.90; 95% CI 1.12 to 13.5). Percentages of women with CT (CT/GC) who were diagnosed with PID also rose with experience (2.2% (3.9%) to 14.2% (13.7%)), but CT prevalence in PID cases diagnosed by inexperienced clinicians (8.8%) was no greater than in all women they assessed (9.0%), suggesting poorer discriminative skills. CONCLUSIONS: Clinical diagnostic acumen for PID improves with experience. Inexperienced clinicians should focus on the presence of lower abdominal pain with pelvic tenderness and consider additional supportive symptoms, to improve specificity of their diagnoses.
