Hospital clinical research activity, rather than staff motivational engagement, significantly links effective staff communication and favourable patient feedback; a cross-sectional study.

OBJECTIVES: Healthcare staff behaviour can impact on the performance of hospitals. Staff involvement in clinical research can have a wider positive effect on patients and hospital performance. The aim of this study was to further assess the putative positive effect of clinical research activity on patient feedback with a more recent dataset, and if staff's motivational engagement levels may impact on aspects of in-patient feedback. METHODS: A retrospective cross-sectional study was conducted with (survey) data from 2019; the sample was 129 English National Health Service hospital Trusts. Sources were the national in-patient survey, national staff survey (for staff motivational engagement), and research activity (based on Trust size-corrected National Institute for Health Research records data). Spearman correlation analyses were conducted (minimum rho value 0.25, p-value<0.005), followed by principal component analysis (score cut-off 0.2). RESULTS: Initial correlation analyses identified eleven in-patient survey questions where better in-patient feedback was associated with increased clinical research activity, and only three questions linked with higher degree of staff motivational engagement. Subsequent principal component analysis confirmed that increased staff engagement is mainly linked to overall Trust performance such as staff levels, whereas staff in research-active hospitals provided in-patients with sufficient information - including on medication - and did well answering patient questions. CONCLUSIONS: Staff involvement in clinical research is associated with better patient feedback. Clear and thorough information provision to patients, may be a mechanism for improved patient outcomes including mortality.

Relationship between staff thriving, through engagement and research activity, and hospital-related outcome measures: A retrospective cross-sectional study.

INTRODUCTION AND OBJECTIVES: Both the standardised hospital mortality index (SHMI) and Care Quality Commission (CQC) ratings are used by the National Health Service (NHS) to monitor performance in English hospitals. We assessed if staff thriving, the concept of vitality and learning at work, through application of the surrogate measures engagement and research activity is associated with more favourable hospital performance outcomes. METHODS: This concerned a retrospective cross-sectional study using data for 129 English NHS hospital Trusts from the year 2019. Outcome measures were SHMI (linear regression, unstandardised coefficient beta) and CQC (binary logistic regression, odds ratio [OR]), whereas the independent variables considered were hospital location, degree of patient deprivation, research activity (drawn from National Institute for Health Research records and controlled for hospital size), and staff engagement scores (based on three survey questions corresponding to validated engagement factors). RESULTS: Staff engagement accounted for over half of the 13% variance R2 for the whole model related to improved CQC rating (OR 13.75, p-value 0.002). Increased research activity was associated with a lower SHMI score (unstandardized beta -0.024, p-value 0.007, R2 5% for each point change in research activity quotient), but independently from the higher SHMI seen for Northern hospital Trusts (beta 0.063, p-value 0.003, R2 11.6%). The degree of patient deprivation did not influence SHMI or CQC outcomes in the regression models. CONCLUSION: Increased staff thriving exhibits a modest, yet significantly, association with improved hospital performance; this was observed despite an underlying regional dichotomy in mortality rates.

Hospital Workforce Engagement and Inpatient Mortality Rate: Findings from the English National Health Service Staff Surveys.

BACKGROUND: Healthcare workforce engagement may represent a proactive approach against provider burnout, a widely prevalent condition that is associated with poor patient outcomes. OBJECTIVE: We examine whether workforce engagement is associated with better hospital performance, measured as lower inpatient mortality, in English National Health Services (NHS) acute Trusts. DESIGN: Panel study using cross-lagged regression, applying an optimally time-lagged value of the dependent variable as covariate to account for unmeasured Trust characteristics. PARTICIPANTS: NHS acute Trusts and respondents to the NHS Staff Surveys, 2012-2018. MAIN MEASURES: We measured engagement using three survey questions corresponding to validated engagement factors, and hospital performance using the Summary Hospital-level Mortality Indicator (SHMI). In the first analyses, associations of SHMI (dependent variable) with workforce engagement in the current, prior, and subsequent years were studied to find the optimum lag period for lagged regression analysis. In the subsequent cross-lagged regression analysis, bi-directional associations between SHMI and engagement were studied. Heterogeneity in engagement components across Trusts was studied in detail for the year 2017. KEY RESULTS: In the first analyses, current SHMI was negatively associated with engagement in the current year (ß = - 0.044; p = 0.035) more than with the prior year (ß = - 0.037; p = 0.049). In the second analysis, (a) engagement predicted same-year SHMI after controlling for prior-year SHMI (ß = - 0.044; p = 0.035). A 1-unit higher engagement score was associated with 4.4% lower SHMI. (b) SHMI predicted engagement in the same year (ß = - 0.066; p = 0.001) after controlling for prior-year engagement. More in-depth analysis showed high inter-trust heterogeneity on all three engagement factors (I2 > 85%). CONCLUSION: Higher workforce engagement predicts lower mortality which in turn predicts engagement. Heterogeneity in workforce well-being suggests an opportunity to foster mutual learning across Trusts.

Teaching clinical informatics to third-year medical students: negative results from two controlled trials.

BACKGROUND: Prior educational interventions to increase seeking evidence by medical students have been unsuccessful. METHODS: We report two quasirandomized controlled trials to increase seeking of medical evidence by third-year medical students. In the first trial (1997-1998), we placed computers in clinical locations and taught their use in a 6-hour course. Based on negative results, we created SUMSearch, an Internet site that automates searching for medical evidence by simultaneous meta-searching of MEDLINE and other sites. In the second trial (1999-2000), we taught SUMSearch's use in a 5(1/2)-hour course. Both courses were taught during the medicine clerkship. For each trial, we surveyed the entire third-year class at 6 months, after half of the students had taken the course (intervention group). The students who had not received the intervention were the control group. We measured self-report of search frequency and satisfaction with search quality and speed. RESULTS: The proportion of all students who reported searching at least weekly for medical evidence significantly increased from 19% (1997-1998) to 42% (1999-2000). The proportion of all students who were satisfied with their search results increased significantly between study years. However, in neither study year did the interventions increase searching or satisfaction with results. Satisfaction with the speed of searching was 27% in 1999-2000. This did not increase between studies years and was not changed by the interventions. CONCLUSION: None of our interventions affected searching habits. Even with automated searching, students report low satisfaction with search speed. We are concerned that students using current strategies for seeking medical evidence will be less likely to seek and appraise original studies when they enter medical practice and have less time.

Case-finding for depression in primary care: a randomized trial.

PURPOSE: Depression is a highly prevalent, morbid, and costly illness that is often unrecognized and inadequately treated. Because depression questionnaires have the potential to improve recognition, we evaluated the accuracy and effects on primary care of two case-finding instruments compared to usual care. SUBJECTS AND METHODS: The study was conducted at three university-affiliated and one community-based medical clinics. Consecutive patients were randomly assigned to be asked a single question about mood, to fill out the 20-item Center for Epidemiologic Studies Depression Screen, or to usual care. Within 72 hours, patients were assessed for Diagnostic and Statistical Manual of Mental Disorders Third Revised Edition (DSM-III-R) disorders by an assessor blinded to the screening results. Process of care was assessed using chart audit and administrative databases; patient and physician satisfaction was assessed using Likert scales. At 3 months, depressed patients and a random sample of nondepressed patients were re-assessed for DSM-III-R disorders and symptom counts. RESULTS: We approached 1,083 patients, of whom 969 consented to screening and were assigned to the single question (n = 330), 20-item questionnaire (n = 323), or usual care (n = 316). The interview for DSM-III-R diagnosis was completed in 863 (89%) patients; major depression, dysthymia, or minor depression was present in 13%. Both instruments were sensitive, but the 20-item questionnaire was more specific than the single question (75% vs 66%, P = 0.03). The 20-item questionnaire was less likely to be self-administered (54% vs 90%) and took significantly more time to complete (15 vs 248 seconds). Case-finding with the 20-item questionnaire or single question modestly increased depression recognition, 30/77 (39%) compared with 11/38 (29%) in usual care (P = 0.31) but did not affect treatment (45% vs 43%, P = 0.88). Effects on DSM-III-R symptoms were mixed. Recovery from depression was more likely in the case-finding than usual care groups, 32/67 (48%) versus 8/30 (27%, P = 0.03), but the mean improvement in depression symptoms did not differ significantly (1.6 vs 1.5 symptoms, P = 0.21). CONCLUSIONS: A simple question about depression has similar performance characteristics as a longer 20-item questionnaire and is more feasible because of its brevity. Case-finding leads to a modest increase in recognition rates, but does not have consistently positive effects on patient outcomes.

Treatment of depression--newer pharmacotherapies.

OBJECTIVES: Depressive disorders are persistent, recurring illnesses that impose enormous personal suffering on individuals and their families. Major depression alone is estimated as the fourth most important cause of worldwide loss in disability-adjusted life years and is likely to become the second most important within 20 years. A continued quest for more effective treatments has spawned newer antidepressants and herbal treatments, which have contributed to explosive growth in antidepressant prescribing, increasing pharmacy costs, and wider but sometimes confusing choices for clinicians and patients. This evidence report provides a comprehensive evaluation of the benefits and adverse effects of newer pharmacotherapies and herbal treatments for depressive disorders in adults and children. SEARCH STRATEGY: Pertinent literature from 1980 to January 1998 was identified from a specialized registry of controlled trials, meta-analyses, and experts. The registry contained trials addressing depression that had been identified from multiple electronic bibliographic databases, hand searches of journals, and pharmaceutical companies. The search, which yielded 1,277 records, combined terms "depression," "depressive disorder," or "dysthymic disorder" with a list of 32 specific "newer" antidepressant and herbal treatments. SELECTION CRITERIA: Randomized controlled trials were reviewed if they (1) were at least 6 weeks in duration; (2) compared a "newer" antidepressant with another antidepressant (newer or older), placebo, or psychosocial intervention; (3) involved participants with depressive disorders; and (4) had a clinical outcome. Two or more independent reviewers identified 315 trials that met these criteria. DATA COLLECTION AND ANALYSIS: Two persons independently abstracted data from each trial. Data were synthesized descriptively, paying attention to participant and diagnostic descriptors, intervention characteristics, study designs and clinical outcomes. Some data were analyzed quantitatively using an empirical Bayes random-effects estimator method. Primary outcomes were response rate, total discontinuation rates (dropouts), and discontinuation rates due to adverse events. Response rates were defined as a 50 percent or greater improvement in symptoms as assessed by a depression symptoms rating scale or a rating of much or very much improved as assessed by a global assessment method. MAIN RESULTS: There were 264 trials that evaluated antidepressants in patients (adults and children) with major depression. Of these, 81 compared newer agents with placebo, 150 newer with older agents, 32 newer agents with newer agents, and 1 newer agent with psychotherapy. There were 14 trials evaluating hypericum (St. John's wort), 27 trials each in primary care patients and older adults, 10 trials limited to patients with specific concomitant illnesses, 9 trials in patients with dysthymia, 3 trials each in patients with mixed anxiety depression and subsyndromal depression, 2 trials in adolescents, and 1 in the postpartum setting. Most trials were conducted in outpatients and examined only acute phase treatment of less than 12 weeks' duration. Newer antidepressants were more effective than placebo in treating major depression (risk ratio 1.6, 95% CI 1.5 to 1.7) and dysthymia (risk ratio 1.7, 95% CI 1.3 to 2.3). They were effective among older adults and in primary care patients. In general, there were no significant differences in efficacy among individual newer agents or between newer and older agents. Hypericum (St. John's wort) was more effective than placebo in treating mild to moderately severe depressive disorders (risk ratio 1.9, 95% CI 1.2 to 2.8). Whether hypericum (St. John's wort) is as effective as standard antidepressant agents given in adequate doses was not established. No significant differences were found between newer and older antidepressants in overall discontinuation rates. Selective serotonin reuptake inhibitors (SSRIs), reversi

Is screening for chronic obstructive pulmonary disease justified?

BACKGROUND: Many experts recommend spirometry to screen for chronic obstructive pulmonary disease (COPD) in asymptomatic patients; however, evidence for this recommendation has not been systematically reviewed. METHODS: We examined whether screening spirometry meets standard criteria for effective screening. We performed structured searches of MEDLINE, followed by a selective search of the CITATION index, to locate randomized trials of interventions for asymptomatic patients with COPD. In regard to smoking cessation, we included all controlled trials of smoking cessation programs that used spirometry. We also included all studies that assessed the ability of spirometry to predict successful smoking cessation by comparing baseline lung function in smokers who subsequently quit versus those who did not. RESULTS: With the exception of smoking cessation, all interventions for COPD have only been proven effective in symptomatic patients. Two studies found that multifaceted smoking cessation programs that included spirometry were efficacious. There was no effect in a third study that isolated the role of spirometry. Smokers with abnormal spirometric results are less likely than other smokers to quit over the ensuing year. CONCLUSIONS: There is no evidence that spirometry, as an isolated intervention, aids smoking cessation.

Can the clinical examination diagnose left-sided heart failure in adults?

We systematically reviewed the literature to ascertain how well clinicians determine the probability and type of left-sided heart failure in their patients. Left-sided heart failure is characterized by decreased left ventricular ejection fraction or increased filling pressure. The type of heart failure determines optimal treatment. Systolic dysfunction exists when ejection fraction is reduced. Diastolic dysfunction is presumed to be present when filling pressure is increased with a normal ejection fraction and without another explanatory diagnosis. Many findings are associated with heart failure, and wide variation exists in clinicians' ability to detect these findings. The best findings for detecting increased filling pressure are jugular venous distention and radiographic redistribution. The best findings for detecting systolic dysfunction are abnormal apical impulse, radiographic cardiomegaly, and q waves or left bundle branch block on an electrocardiogram. Diastolic dysfunction is especially difficult to diagnose, but is associated with an elevated blood pressure during heart failure.

Using systematic reviews in clinical education.

Traditional educational methods change clinical practice only with considerable effort and difficulty. In particular, the teaching of critical appraisal in the setting of journal clubs does not increase the amount of medical research read by trainees. Experiential learning theory, corroborated by the success of problem-based learning, encourages us to link learning to the numerous medical questions that physicians generate while providing patient care. Systematic reviews can link these questions with the results of research that would otherwise be difficult to locate, read, and appraise. Systematic reviews are a uniquely powerful mechanism for teaching, and they offer teachers a new opportunity to model rational and effective use of information. Systematic reviews should be made available at clinical sites for use during "teachable moments." Resistance to the use of systematic reviews can be reduced by using existing journal clubs to teach about the strengths and limitations of these reviews. The point that systematic reviews are meant to assist, not replace, clinical decision making deserves emphasis in such teaching.

Knowledge and attitudes about depression among non-generalists and generalists.

BACKGROUND: The purpose of this study was to learn more about barriers to managing depression by comparing knowledge and attitudes about depression among physicians, internists, obstetrician-gynecologists, and a reference group of psychiatrists. Among the non-psychiatrists, we hypothesized that generalist physicians would have more favorable attitudes and greater knowledge about depression than non-generalists. METHODS: Survey questionnaires were sent to resident and faculty physicians (N = 375) of two university-affiliated medical centers. The physicians were classified as non-generalists (medicine subspecialists, transitional year interns, and obstetrician-gynecologists), generalists (general internists and family physicians), and psychiatrists. A 33-item written questionnaire assessed knowledge and three attitudinal dimensions: attitudes attributed by physicians to patients; physicians' confidence in managing depression; and physicians' psychosocial orientation. A knowledge scale and an attitudes scale were scored by adding the number of knowledge items answered correctly and the more favorable attitudinal responses. Multivariable regression was used to identify physician characteristics among non-generalists and generalists associated with higher knowledge and attitudinal scores. RESULTS: Response rate was 82%. Sixty percent of the respondents were male, 63% were resident physicians, and 14% had advanced psychosocial training. Non-generalists and generalists had similar demographic characteristics, but psychiatrists were significantly more experienced. Psychiatrists had the most favorable attitudes, followed by generalists and non-generalists. Compared with non-generalists, generalists were more confident in prescribing antidepressants (62% vs 25%), more likely to report that treating depression is rewarding (71% vs 39%), and less likely to refer to a psychiatrist (58% vs 79%). Generalist classification, increased experience, and higher levels of psychosocial training were associated with more favorable attitudes. Knowledge scores were significantly higher for psychiatrists than for non-generalists and generalists. Among non-psychiatrists, correct responses for knowledge items were: treatment efficacy (61%), treatment duration (59%), > or = 5 DSM-III-R criteria (52%), and prevalence of depression (30%). Among those with incorrect responses, both non-generalists and generalists overestimated the prevalence (52%) and underestimated the efficacy of drug therapy (30%). CONCLUSIONS: Generalists and non-generalists have similar and relatively good basic knowledge about depression. Misperceptions about treatment efficacy, and attitudinal barriers, particularly among non-generalists, may compromise the physician's ability to diagnose and manage depression.

How well can the chest radiograph diagnose left ventricular dysfunction?

OBJECTIVES: To review the diagnostic utility of the chest radiograph for left ventricular dysfunction. DATA SOURCES: Structured MEDLINE searches, citation reviews of relevant primary research, review articles, and textbooks, personal files, and data from experts. STUDY SELECTION: Studies of patients without valvular disease that allowed calculation of the sensitivity and specificity of selected radiographic signs compared with a criterion standard of increased left ventricular preload or reduced ejection fraction. DATA EXTRACTION: Two independent readers reviewed 29 studies. Studies were pooled after stratification by radiographic finding, criterion standard, and clinical setting. MAIN RESULTS: Redistribution best diagnosed increased preload with a sensitivity of 65% (95% confidence interval [CI] 55%, 75%) and specificity 67% (95% CI 53%, 79%). Cardiomegaly best diagnosed decreased ejection fraction with a sensitivity of of 51% (95% CI 43%, 60%) and specificity of 79% (95% CI 71%, 85%). Interrater reliability was fair to moderate for redistribution and moderate for cardiomegaly. The clinical setting affected results by decreasing the specificity of cardiomegaly to 8% in detecting increased preload in patients with severe systolic dysfunction. The absence of redistribution could only exclude increased preload in situations in which the suspicion (pretest probability) of disease was less than 9%, whereas redistribution could confirm increased preload when the pretest probability was greater than 91%. The absence of cardiomegaly could only exclude a reduced ejection fraction if the pretest probability was less than 8%, whereas cardiomegaly could confirm a reduced ejection fraction if the pretest probability was greater than 87%. CONCLUSIONS: Redistribution and cardiomegaly are the best chest radiographic findings for diagnosing increased preload and reduced ejection fraction, respectively. Unfortunately, neither finding alone can adequately exclude or confirm left ventricular dysfunction in usual clinical settings. Redistribution is not always reliably interpreted.

Medical student career choice: do physical diagnosis preceptors influence decisions?

The authors attempted to measure the influence of a physical diagnosis course and its preceptors on the career decisions of second-year medical students. They designed pre- and post-course questionnaires for 204 second-year medical students in a University of Texas Health Science Center at San Antonio Advanced Physical Diagnosis course. They found that 48% of students changed their career choice during the study period, 75% believed their preceptor was a very good role model, and 39% thought their preceptor influenced their career choice. Students who believed their preceptor was a good role model were 31 times more likely to consider their preceptors' career (confidence interval [CI] 95, 4.1-236). In results from students precepted by primary care physicians, there was a nonsignificant trend toward choosing a primary care career (Odds Ratio [OR]) 1.6 [CI95, 0.7-3.3]). Factors associated with a final career choice of primary care were a primary care career choice at baseline (OR 8.5 [CI95, 3.8-19.0]) and a belief that physical diagnosis skills would be important to a future career (OR 4.7 [CI95, 1.1-20.0]). By multivariable analysis, only a primary care career choice at baseline remained significant (OR 8.7 [CI95, 3.5-21.3]). The authors concluded that good role models can influence students to consider alternative career choices, but this effect is still overshadowed by a student's baseline career choice.(ABSTRACT TRUNCATED AT 250 WORDS)

Safety belt nonuse by internal medicine patients: a missed opportunity in clinical preventive medicine.

BACKGROUND: The United States Preventive Services Task Force recommends that physicians routinely counsel all patients to wear safety belts. We undertook this study to determine the prevalence of the nonuse of safety belts among internal medicine patients, to measure the association of nonuse with other health risk factors, and to ascertain the safety belt counseling practices of physicians. PATIENTS AND METHODS: A total of 492 consecutive patients attending a university-based general medicine clinic were given a validated, self-administered questionnaire, and 94% responded. A medical chart review was performed in a blinded fashion on 94% of the eligible charts. RESULTS: Of the 454 patients who provided safety belt information, 243 (54%) did not wear safety belts. Nonusers were more likely to be problem drinkers, inactive, obese, and to have a low income (adjusted odds ratios 1.8 to 2.0). Of patients with all four of these characteristics, 91% did not use safety belts. The leading reasons for safety belt nonuse were discomfort (35%), short driving distances (24%), and forgetfulness (13%). Obese patients were more likely to report discomfort as their reason for nonuse (odds ratio 2.4; 95% confidence limit 1.4 to 4.3). Eighteen patients (3.9%) reported that a physician had ever counseled them about safety belt use. Only two of 314 medical records (0.6%) noted physician questioning or counseling about safety belt use. CONCLUSIONS: The majority of patients attending an internal medicine clinic do not wear safety belts. Nonusers are more likely to be problem drinkers, inactive, obese, and to have a low income. Patients with multiple health risk factors are at significant risk of nonuse. The most common reason for nonuse is physical discomfort, especially among obese patients. Finally, physicians rarely counsel patients to use safety belts.

The clinical evaluation for diagnosing obstructive airways disease in high-risk patients.

OBJECTIVE: We measured the ability of the medical history, physical examination, and peak flowmeter in diagnosing any degree of obstructive airways disease (OAD). DESIGN: Prospective comparison of historical and physical findings with independently measured spirometry. SETTING: University outpatient clinic. PATIENTS: Ninety-two adult consecutive outpatient volunteers with a self-reported history of smoking, asthma, chronic bronchitis, or emphysema. MEASUREMENTS: All subjects completed a pulmonary history questionnaire and received peak flow (PF) and spirometric testing. The subjects were independently examined for 12 pulmonary physical signs by four internists blinded to all other results. Multivariable analysis was used to create a diagnostic model to predict OAD as diagnosed by spirometry (FEV1 < 80 percent of predicted not secondary to restrictive disease, or FEV1/FVC less than 0.7). RESULTS: The best model diagnosed OAD when any of three variables were present--a history of smoking more than 30 pack-years, diminished breath sounds, or peak flow less than 350 L/min. This model had a sensitivity of 98 percent and specificity of 46 percent. In addition, the model detected all subjects with probable restrictive lung disease. Thirty-one percent of subjects had none of these variables and were at very low (3 percent) risk of OAD. Fifty percent of subjects with one or more abnormal variables had OAD. CONCLUSIONS: The history, physical examination, and peak flowmeter can be used to screen high-risk patients for OAD. Using this diagnostic model, 31 percent of subjects could be classified at very low risk of OAD while half of those referred for spirometry would have abnormal results.

Clinical and sociocultural determinants of gallstone treatment.

Cholecystectomy remains the principal treatment for gallstones. Many gallstone patients do not undergo surgery within 6 months of diagnosis. To determine factors associated with cholecystectomy, treated and untreated patients were compared with respect to clinical and sociodemographic factors. The study population was comprised of outpatients of a public system evaluated in an emergency room or at a community health center. All were interviewed in English or Spanish before completing imaging studies. Of 121 found to have gallstones, 75 underwent early cholecystectomy. Patients reporting episodes of prolonged abdominal pain more often had surgery (p < 0.003). Patients evaluated in the emergency room underwent surgery more often than those from the community health center (p < 0.04). Patient ethnicity was unrelated to treatment, but Mexican Americans who requested interviews in Spanish were less likely to undergo cholecystectomy (p < 0.05). After logistic regression, prolonged abdominal pain was the only significant predictor of surgical management, although relationships with language use and site of diagnosis persisted. It was concluded that clinical presentation largely determines surgical treatment for gallstones but site of diagnosis is also a factor. Patients with poor English language skills undergo cholecystectomy less often. This may be due to poor doctor-patient communication, or it may be a reflection of cultural factors linked to language use.
