There is a growing evidence base on methods to improve response rates in surveys among patients. This study aimed to determine the additional effect of two intensive follow-up procedures compared to a simple follow-up procedure.
                Randomized controlled trial that compared repeated mailing of the questionnaire and a request to explain nonparticipation with a simple reminder card. The study population comprised 955 elderly adults registered with 26 general practitioners in The Netherlands.
                A total of 530 adults (56%) returned the questionnaire within 3 weeks and a total of 640 (67%) after follow-up. Repeated mailing of the questionnaire had additional effect compared to the simple reminder card in the group of initial nonresponders (relative risk=1.60, 95% confidence interval: 1.11-2.31), but not regarding the overall response rate. A request to explain nonparticipation did not have additional effect.
                Repeated mailing of the questionnaire increased the effectiveness of follow-up among initial nonresponders. To determine whether alternative methods of presenting a contrast between the same two quantities in descriptions of research results could lead to different treatment decisions by physicians.
                We conducted a survey of practicing physicians and of faculty and fellows in training programs in clinical epidemiology and social science research methods. Each questionnaire presented results from a published study of either hypertension or hypercholesterolemia in two different ways: once as the relative change in the outcome rate and once as the absolute change in the outcome rate. We asked respondents to read each summary and indicate how the information contained in the summary would influence decisions about treatment.
                Of the 235 physicians who completed the questionnaire, 108 (46%) gave different responses to the same results presented in different ways. Of these, 97 (89.8%) indicated a stronger inclination to treat patients after reading of the relative change in the outcome rate (p less than 0.0001).
                The manner of presentation of results can influence physicians' judgments about the treatment of patients. Family psychoeducation has a well-documented effect on the short-term prognosis in schizophrenia. Less is known about the effectiveness of shorter programmes with the main focus on information for patients (patient education) or for patients and relatives (family education).
                A randomized study of the effectiveness of an eight-session psychoeducational programme for patients with schizophrenia and for their relatives was conducted in two community mental health centres, in Arhus and Viborg (Denmark). Patient outcome measures were knowledge, relapse, compliance, insight and satisfaction, and relative outcome measures were knowledge and satisfaction. Post-intervention outcome and follow-up evaluation 1 year after the start of the intervention are presented.
                A statistically significant increase in knowledge of schizophrenia in both relatives and patients was demonstrated at postintervention and a non-significant trend at 1-year follow-up. Statistically significant changes in the Verona Service Satisfaction Scale Scores in the subdimension of satisfaction with Relatives involvement were demonstrated both for patients and relatives postintervention and for patients at 1-year follow-up. There was a tendency that time-to-relapse increased in the intervention group at postintervention and that the schizophrenia subscore of the Brief Psychiatric Rating Scale was reduced in the intervention group at 1-year follow-up. No differences were found between the groups regarding compliance, insight into psychosis, psychosocial function (General Assessment of Function) or in relatives' expressed emotion scores postintervention or at 1-year follow-up.
                A short patient and relative education programme seems to be able to influence knowledge and some aspects of satisfaction, but does not seem to be sufficient to influence important variables such as relapse, compliance, psychopathology, insight or psychosocial functioning. To evaluate and compare the effects of two types of continuing medical education (CME) programs on the communication skills of practicing primary care physicians.
                Fifty-three community-based general internists and family practitioners practicing in the Portland, Oregon, metropolitan area and 473 of their patients.
                For the short program (a 4 1/2-hour workshop), 31 physicians were randomized to either the intervention or the control group. In the long program (a 2 1/2-day course), 20 physicians participated with no randomization. A research assistant visited all physicians' offices both one month before and one month after the CME program and audiotaped five sequential visits each time. Data were based on analysis of the content and the affect of the interviews, using the Roter Interactional Analysis Scheme.
                Based on both t-test analysis and analysis of covariance, no effect on communication was evident from the short program. The physicians enrolled in the long program asked more open-ended questions, more frequently asked patients' opinions, and gave more biomedical information than did the physicians in the short program. Patients of the physicians who attended the long program tended to disclose more biomedical and psychosocial information to their physicians. In addition, there was a decrease in negative affect for both patient and physician, and patients tended to demonstrate fewer signs of outward distress during the visit.
                This study demonstrates some potentially important changes in physicians' and patients' communication after a 2 1/2-day CME program. The changes demonstrated in both content and affect may have important influences on both biologic outcome and physician and patient satisfaction. Mailed questionnaires are an economical method of data collection for epidemiologic studies, but response tends to be lower than for telephone or personal interviews. As part of a follow-up study of volunteers who provided a brief health history and blood sample for a blood specimen bank in 1989, the authors conducted a controlled trial of the effect of length, incentives, and follow-up techniques on response to a mailed questionnaire. Interventions tested included variations on length of the questionnaire, effect of a monetary incentive, and effect of a postcard reminder versus a letter accompanied by a second questionnaire. Response was similar for the short (16-item, 4-page) and long (76-item, 16-page) questionnaire groups. The non-monetary [corrected] incentive did not improve the frequency of response. The second mailing of a questionnaire was significantly better than a postcard reminder in improving responses (23% vs. 10%). It is important to systematically test marketing principles to determine which techniques are effective in increasing response to mailed questionnaires for epidemiologic studies. Despite evidence of high psychological distress and unmet needs, evaluated interventions for informal caregivers in palliative care are few. This study involved an observational outcome evaluation of attendees, and a comparison group, in specialist home palliative care. The measures included carer psychological status and patient physical status at baseline, 8 weeks, and 20 weeks. Qualitative data were collected regarding content, satisfaction with, and impact of intervention. Process data described the uptake, resources, and group activity. The intervention combined informal multiprofessional teaching with facilitated peer exchange and support, and was delivered over 6 sessions of 90 minutes per week. The uptake rate was 25%; carers were less likely to accept if they were in paid employment (OR=0.26, P=0.06), and more likely to accept if they utilized avoidance coping (OR=1.13, P=0.04) or their patient had worse physical status (OR=2.1, P=0.03). Attendees described significant support and knowledge gains from the multiprofessional input and peer group. Most relied on social comparison processes to appraise their situation. Potential detection of significant effects on global psychological scores (i.e. anxiety, depression, and burden) using multivariate analysis was disallowed due to attrition. This acceptable and accessible intervention provided information and support; further outcome studies are needed for a range of interventions. Short-term interventions are unlikely to affect global psychological scores, and future evaluations should include additional time points of data collection to demonstrate support during attendance. To determine if a relationship exists between structured, informative in-home teaching concerning infant behavior and primiparous mothers' perceptions of their newborn, 30 primiparas completed Broussard's Neonatal Perception Inventories I and II. The sample--30 women between the ages of 18 and 30 who had had no chronic disorders and had experienced normal pregnancy, labor, delivery, and postpartal course--was deliberately selected from a 489-bed community teaching hospital; 15 women were assigned randomly to a control group and 15 to an experimental group. All participants completed NPI I on their first or second postpartum day. Experimental participants received structured, informative teaching concerning infant behavior two to four days after discharge. All subjects were again visited at one month to complete NPI II. Data were analyzed by t test; significance was set at p = .05. No significant difference was found between the groups in NPI I perceptions. On NPI II a significantly positive change in perception was found for the experimental group, but not for the control group. To investigate the relationship between industry- vs nonindustry-funded publications comparing the efficacy of topical prostaglandin analogs by evaluating the correspondence between the statistical significance of the publication's main outcome measure and its abstract conclusions.
                Retrospective, observational cohort study.
                English publications comparing the ocular hypotensive efficacy between any or all of latanoprost, travoprost, and bimatoprost were searched from the MEDLINE database. Each article was reviewed by three independent observers and was evaluated for source of funding, study quality, statistically significant main outcome measure, correspondence between results of main outcome measure and abstract conclusion, number of intraocular pressure outcomes compared, and journal impact factor. Funding was determined by published disclosure or, in cases of no documented disclosure, the corresponding author was contacted directly to confirm industry funding. Discrepancies were resolved by consensus. The main outcome measure was correspondence between abstract conclusion and reported statistical significance of the publications' main outcome measure.
                Thirty-nine publications were included, of which 29 were industry funded and 10 were nonindustry funded. The published abstract conclusion was not consistent with the results of the main outcome measure in 18 (62%) of 29 of the industry-funded studies compared with zero (0%) of 10 of the nonindustry-funded studies (P = .0006). Twenty-six (90%) of the industry-funded studies had proindustry abstract conclusions.
                Twenty-four percent of the industry-funded publications had a statistically significant main outcome measure; however, 90% of the industry-funded studies had proindustry abstract conclusions. Both readers and reviewers should scrutinize publications carefully to ensure that data support the authors' conclusions. We studied two methods to reduce the ordering of laboratory and radiologic tests by medical residents in their first postgraduate year. Dividing the residents into three groups, we compared the effect of concurrent chart review and discussion in one group with the effect of a moderate financial incentive for limited ordering of tests in a second group. The third group of residents served as a concurrent control, and data on the testing patterns of residents at the same hospital during the year before the study provided a retrospective control.
The small number of participants and the short follow-up period impede definitive conclusions on comparative effects.
