PurposeAlthough an adult model of patient-provider mutual exchange of information has been proposed, there is no guiding model for adolescents or measurement methodology. Our purpose was to develop a new scale of patient-provider interaction for adolescents accessing reproductive health care and at risk for sexually transmitted diseases (STDs) and human immunodeficiency virus (HIV), and assess the reliability and validity of the scale.MethodsThe Adolescent Patient-Provider Interaction Scale (APPIS) was developed from the Roter and Hall theory of doctor-patient relationships, previously validated adolescent satisfaction and communication scales, and focus group and individual elicitation interviews. To assess construct validity, the new nine-item APPIS was compared with the satisfaction scale used by the Young Adult Health Care Survey (YAHCS), and Kahn’s Provider Communication Scale. Pearson correlation coefficients were used to examine convergence across scales, and factor analysis of the APPIS was performed.ResultsThe study recruited 192 African American girls aged 17.9 ± 1.7 years (range 15–21 years) from three sites: a county STD clinic (n = 51), urban adolescent clinic (n = 99), and a family planning clinic (n = 42). Most participants (85%) rated their overall health care highly (≥ 7 on a 10-point scale); 49% felt that both the provider and patient were “in charge” of the visit, and 88% “strongly agreed” or “agreed” that there was an equal “exchange of information” during the visit. The APPIS showed good internal consistency (Cronbach alpha = .75), and moderate convergence with the six-item YAHCS scale (r = .57, p < .001) and seven-item Kahn scale (r = .48, p < .001). Three factors emerged from exploratory factor analyses, supporting our conceptualization of patient-provider interaction as being multi-dimensional.ConclusionsA new theory-based scale of adolescent patient-provider interaction compares favorably with previous scales of health care satisfaction and communication. The new APPIS may be useful for evaluating approaches to improve health care outcomes for adolescents at-risk for STDs and HIV.  相似文献

Potential advantages of paediatric day-surgery are cost saving, improved utilization of staff and hospital facilities, and reduction of stress for the paediatric patient and their family. A successful programme requires careful case selection, full operating and anaesthetic facilities and good follow-up. Current practice is reviewed with regard to initial assessment, preparation for surgery and overall management during the day admission. To provide information on how patients and their parents experience essential aspects of daycare paediatric surgery, a questionnaire-based study on parental satisfaction of paediatric day-surgery was performed. Most children were back to normal, within a few days. Recovery from paediatric day-surgery was rapid and the overall level of parent satisfaction was high.  相似文献

The aim of this study was to investigate factors associated with life dissatisfaction in symptomatic patients (n = 144) with chest pain subsequently diagnosed as coronary heart disease (CHD) by coronary angiography. Life dissatisfaction was assessed with a four-item life satisfaction scale (LS), depression with the 21-item Beck Depression Inventory (BDI) and other psychiatric symptoms with the symptom check list (SCL). DSM-III-R Axis I and Axis II psychiatric diagnoses were performed by means of the Structured Clinical Interview. All assessments took place one day before angiography. Twenty-four per cent of CHD patients were dissatisfied with their lives. Life dissatisfaction was associated with being unmarried. Dissatisfied patients had Axis I mental disorders and Axis II personality disorders more frequently than others. Psychiatric and depressive symptoms according to the SCL and BDI, respectively, were also higher among dissatisfied patients. In multiple logistic regression analyses, mental disorders were related to life dissatisfaction when age, sex, employment status, New York Heart Association class, duration of chest pain symptoms and work load were controlled in the model. Married subjects had a lower probability of being dissatisfied with their lives than other subjects (Odds Ratio, OR: 0.23). When BDI scores were included in the model, the only factor independently associated with life dissatisfaction was the severity of depressive symptoms (OR: 1.81). To conclude, life dissatisfaction is not primarily determined by the severity of CHD but by the existence of depressive symptoms.  相似文献

A survey by questionnaire was carried out to examine the level of nursing staff satisfaction with the acute psychiatric services. Comparisons were made between views of older psychiatric hospitals and newer district general hospital units, and before and after the closure of Friern Barnet Hospital, London, England when the service was reorganized to include fewer beds. The importance of nurses having their say is emphasized, and areas in which improvements can be made are suggested.  相似文献

This study describes mortality rates and predictors of mortality among late-middle-aged and older (55+) substance abuse inpatients ( n = 21, 139) in Department of Veterans Affairs (VA) Medical Centers in the 4 years after an index episode of care. A total of 24% of the patients died; this mortality rate was 2.64 times higher than expected. Predictors of earlier mortality included older age and nonmarried status, alcohol psychosis and organic brain disorder diagnoses, and several medical diagnoses, including neoplasms, liver cirrhosis, respiratory, endocrine and metabolic, and blood system disorders. Three proxy indicators of illness severity also predicted mortality: more prior inpatient and outpatient medical care and an index episode in an extended care unit. In contrast, more prior outpatient mental health care and remitted status predicted lower mortality. These diagnostic and treatment indicators can be used to identify patients at heightened risk for premature mortality. Moreover, they show that intensive mental health aftercare and remission of substance abuse may delay mortality, even among older patients who have longstanding substance abuse problems.  相似文献

This paper reflects on a research project funded by a consortium of leading sheltered housing (SH) providers and their regulatory body, the Housing Corporation. The project aimed to ascertain which aspects of SH older people perceived to be central to their satisfaction and the methods they judged most appropriate to measuring this. We outline key policy developments of importance to SH (specifically the development of performance measurement regimes), and changes in the nature of SH, which are driving providers to re‐evaluate how they measure user satisfaction. We discuss the aims of the project, our methodology and findings, and conclude by raising critical questions about the process of measuring satisfaction within an increasingly managerialised housing system. We argue that this favours standardised methods of information gathering (such as questionnaires) rather than engage with clients in order to develop methods and systems capable of eliciting qualitative issues of concern to them. Our conclusions are, we believe, applicable to health and social care provision, where similar tensions exist around performance measurement and user satisfaction.  相似文献

OBJECTIVES: To examine patient satisfaction with and recommendation of a hospital, with a special focus on the correlation of these measures to patient ratings of interpersonal and technical performance of the hospital. DESIGN: Telephone survey of patients with four specific conditions after their discharge from hospitals. SETTING: Accredited district teaching hospitals and above, nationwide in Taiwan. PARTICIPANTS: A total of 4945 patients from 126 hospitals diagnosed with or undergoing procedures related to stroke, diabetes mellitus, Caesarean section, or appendectomy were interviewed by telephone. MAIN OUTCOME MEASURES: Overall patient satisfaction and recommendation were measured by single-item questions. Interpersonal skills were measured by three items: doctors' explanation, attitude, and caring. Technical skills were measured by another three items: hospital equipment, clinical competence, and outcome of treatment. RESULTS: Interpersonal skills were as influential or more influential than clinical competence on patient satisfaction for three of the four disease categories. In contrast, technical competence was a more influential predictor for recommendation for patients in all four disease categories. CONCLUSION: The preliminary results imply that a hospital with high percentage of patient satisfaction does not necessarily receive a high level of recommendation. This finding provides new insights for researchers and for hospital managers who devote resources exclusively for achieving the highest possible levels of patient satisfaction.  相似文献
