Assessing patient-centred communication in teaching: A systematic review of instruments

Context Patient-centred communication is a key component of patient centredness in medical care. Therefore, adequate education in and assessment of patient-centred communication skills are necessary. In general, feedback on communication skills is most effective when it is provided directly and is systematic. This calls for adequate measurement instruments. Objectives The aim of this study was to provide a systematic review of existing instruments that measure patient centredness in doctor–patient communication and can be used to provide direct feedback. Methods A systematic review was conducted using an extensive validated search strategy for measurement instruments in PubMed, EMBASE, PsycINFO and CINAHL. The databases were searched from their inception to 1 July 2016. Articles describing the development or evaluation of the measurement properties of instruments that measure patient centredness (by applying three or more of the six dimensions of a published definition of patient centredness) in doctor–patient communication and that can be used for the provision of direct feedback were included. The methodological quality of measurement properties was evaluated using the COSMIN checklist. Results Thirteen articles describing 14 instruments measuring patient centredness in doctor–patient communication were identified. These studies cover a wide range of settings and patient populations, and vary in the dimensions of patient centredness applied and in methodological quality on aspects of reliability and validity. Conclusions This review gives a comprehensive overview of all instruments available for the measurement of patient centredness in doctor–patient communication that can be used for the provision of direct feedback and are described in the literature. Despite the widely felt need for valid and reliable instruments for the measurement of patient-centred communication, most of the instruments currently available have not been thoroughly investigated. Therefore, we recommend further research into and enhancement of existing instruments in terms of validity and reliability, along with enhancement of their generalisability, responsiveness and aspects of interpretability in different contexts (real patients, simulated patients, doctors in different specialties, etc.). Comprehensibility and feasibility should also be taken into account.this study was supported by Radboud University Medical Centre (IWOO [EKO project R0002432]

Assessment of medical students' integrated clinical communication skills: Development of a tailor-made assessment tool

Background Since patient-centered communication is directly connected to clinical performance, it should be integrated with medical knowledge and clinical skills. Therefore, clinical communication skills should be trained and assessed as an integral part of the student’s clinical performance. We were unable to identify a tool, which helps when assessing patient-centered communication skills as an integrated component of medical history taking (‘the integrated medical interview’). Therefore, we decided to design a new tailor-made assessment tool, the BOCC (BeOordeling Communicatie en Consultvoering (Dutch), Assessment of Communication and Consultation (English) to help raters assess students’ integrated clinical communication skills with the emphasis on patient-centred communication combined with the correct medical content. This is a first initiative to develop such a tool, and this paper describes the first steps in this process. Methods We investigated the tool in a group of third-year medical students (n = 672) interviewing simulated patients. Internal structure and internal consistency were assessed. Regression analysis was conducted to investigate the relationship between scores on the instrument and general grading. Applicability to another context was tested in a group of fourth-year medical students (n = 374). Results PCA showed five components (Communication skills, Problem clarification, Specific History, Problem influence and Integration Skills) with various Cronbach’s alpha scores. The component Problem Clarification made the strongest unique contribution to the grade prediction. Applicability was good when investigated in another context. Conclusions The BOCC is designed to help raters assess students’ integrated communication skills. It was assessed on internal structure and internal consistency. This tool is the first step in the assessment of the integrated medical interview and a basis for further investigation to reform it into a true measurement instrument on clinical communication skills.This study was supported by the Radboud University Medical Center Nijmegen (EKO grant)

Kidney and vascular function in adult patients with hereditary fructose intolerance

Objective: Previous studies have shown that patients with hereditary fructose intolerance (HFI) are characterized by a greater intrahepatic triglyceride content, despite a fructose-restricted diet. The present study aimed to examine the long-term consequences of HFI on other aldolase-B-expressing organs, i.e. the kidney and vascular endothelium. Methods: Fifteen adult HFI patients were compared to healthy control individuals matched for age, sex and body mass index. Aortic stiffness was assessed by carotid-femoral pulse wave velocity (cf-PWV) and endothelial function by peripheral arterial tonometry, skin laser doppler flowmetry and the endothelial function biomarkers soluble E-selectin [sE-selectin] and von Willebrand factor. Serum creatinine and cystatin C were measured to estimate the glomerular filtration rate (eGFR). Urinary glucose and amino acid excretion and the ratio of tubular maximum reabsorption of phosphate to GFR (TmP/GFR) were determined as measures of proximal tubular function. Results: Median systolic blood pressure was significantly higher in HFI patients (127 versus 122 mmHg, p = .045). Pulse pressure and cf-PWV did not differ between the groups (p = .37 and p = .49, respectively). Of all endothelial function markers, only sE-selectin was significantly higher in HFI patients (p = .004). eGFR was significantly higher in HFI patients than healthy controls (119 versus 104 ml/min/1.73m2, p = .001, respectively). All measurements of proximal tubular function did not differ significantly between the groups. Conclusions: Adult HFI patients treated with a fructose-restricted diet are characterized by a higher sE-selectin level and slightly higher systolic blood pressure, which in time could contribute to a greater cardiovascular risk. The exact cause and, hence, clinical consequences of the higher eGFR in HFI patients, deserves further study.</p

Risk factors and causes of ischemic stroke in 1322 young adults

Background:Identification of risk factors and causes of stroke is key to optimize treatment and prevent recurrence. Up to one-third of young patients with stroke have a cryptogenic stroke according to current classification systems (Trial of ORG 10172 in Acute Stroke Treatment [TOAST] and atherosclerosis, small vessel disease, cardiac pathology, other causes, dissection [ASCOD]). The aim was to identify risk factors and leads for (new) causes of cryptogenic ischemic stroke in young adults, using the pediatric classification system from the IPSS study (International Pediatric Stroke Study).Methods:This is a multicenter prospective cohort study conducted in 17 hospitals in the Netherlands, consisting of 1322 patients aged 18 to 49 years with first-ever, imaging confirmed, ischemic stroke between 2013 and 2021. The main outcome was distribution of risk factors according to IPSS classification in patients with cryptogenic and noncryptogenic stroke according to the TOAST and ASCOD classification.Results:The median age was 44.2 years, and 697 (52.7%) were men. Of these 1322 patients, 333 (25.2%) had a cryptogenic stroke according to the TOAST classification. Additional classification using the ASCOD criteria reduced the number patients with cryptogenic stroke from 333 to 260 (19.7%). When risk factors according to the IPSS were taken into account, the number of patients with no potential cause or risk factor for stroke reduced to 10 (0.8%).Conclusions:Among young adults aged 18 to 49 years with a cryptogenic ischemic stroke according to the TOAST classification, risk factors for stroke are highly prevalent. Using a pediatric classification system provides new leads for the possible causes in cryptogenic stroke, and could potentially lead to more tailored treatment for young individuals with stroke.Neurological Motor Disorder

Trigger factors for stroke in young adults: a case-crossover study

Background and ObjectivesCauses of stroke in young adults differ from those in the elderly individuals, and in a larger percentage,no cause can be determined. To gain more insight into the etiology of (cryptogenic) stroke in theyoung population, we investigated whether trigger factors, such as short-lasting exposure to toxins orinfection, may play a role.MethodsPatients aged 18–49 years with a first-ever ischemic stroke or intracerebral hemorrhage (ICH) in 17participating centers in the Netherlands completed a questionnaire about exposure to 9 potentialtrigger factors in hazard periods and on a regular yearly basis. A case-crossover design was used toassess relative risks (RRs) with 95% confidence intervals (95% CIs) by the Mantel-Haenszel case-crossover method, for any stroke (ischemic stroke and ICH combined) and for different etiologicsubgroups of ischemic stroke.ResultsOne thousand one hundred forty-six patients completed the questionnaire (1,043 patients withan ischemic stroke and 103 with an ICH, median age 44.0 years, 52.6% men). For any stroke, anincreased risk emerged within 1 hour of cola consumption (RR 2.0, 95% CI 1.5–2.8) and vigorousphysical exercise (RR 2.6, 95% CI 2.2–3.0), within 2 hours after sexual activity (RR 2.4, 95% CI1.6–3.5), within 4 hours after illicit drug use (RR 2.8, 95% CI 1.7–4.9), and within 24 hours afterfever or flu-like disease (RR 14.1, 95% CI 10.5–31.2; RR 13.9, 95% CI 8.9–21.9). Four triggerfactors increased the risk of other determined and cryptogenic ischemic stroke, 3 that of car-dioembolic stroke, 2 that of large vessel atherosclerosis and likely atherothrombotic strokecombined and stroke with multiple causes, and none that of stroke due to small vessel disease.DiscussionWe identified cola consumption, vigorous physical exercise, sexual activity, illicit drug use, fever, andflu-like disease as potential trigger factors for stroke in the young population and found differencesin the type and number of trigger factors associated with different etiologic subgroups of ischemicstroke. These findings might help in better understanding the pathophysiologic mechanisms of(cryptogenic) stroke in the young population.Paroxysmal Cerebral Disorder

Intrathecal Baclofen Overdose: Report of 7 Events in 5 Patients and Review of the Literature

This study is intended to alert the clinician to the insidious symptoms of baclofen overdose, its prevention and treatment. In a group of 43 patients suffering from previously intractable spasticity and a total treatment time of 2,422 weeks, 7 events of intrathecal baclofen overdose happened in 5 patients. On two occasions, a bolus injection caused an overdose (dose 50 and 280-mu-g). The 5 events during continuous infusion intoxication only happened in high dosed patients. The overdose symptoms occurred in one patient when she was lying in supine position (800-mu-g/24 h), in another patient after repair of CSF leakage by an autologous epidural bloodpatch (1,920-mu-g/24 h) and in tolerant patients, once during maximal dose adjustments (2,400-mu-g/24 h) and twice ca. 6 hours following reinitiation of the intrathecal baclofen infusion after a "drug holiday" treatment (27 and 55-mu-g/h). We could not confirm the reported similarity of baclofen overdose with the anticholinergic syndrome. Especially, the bradycardia and hypotension are more in accord with the reported clinical picture of oral baclofen overdose. In the absence of a pure baclofen antagonist and the varying symptoms of intrathecal baclofen, intoxication make rational treatment difficult. We observed that the advised physostigmine therapy is not always effective and safe. The occasionally doubtful antidotal benefits of physostigmine must be weighed against major side-effects. The classical approach of decreasing the absorption of a drug by lowering baclofen levels in the CSF by lumbar puncture drainage was successful. This approach together with conservative symptomatic treatment in an intensive care environment is probably a better and safer alternative than physostigmine alone as an antidote
