Application of a classical model of competitive business strategy to orthodontic practice.

This study explored how market forces might affect the business aspects of orthodontic practices; in particular, profitability. The forces identified were (1) intensity of rivalry, (2) threat of new entrants, and (3) bargaining power of buyers and suppliers. A mail survey instrument was used to collect the data. Results showed that more than half the surveyed practices show an increase in new case starts despite weak economic conditions. Although satellite offices and marketing increase the overhead, they do not add to net profit. New entrants are a threat to existing practices, as are the substitute discretionary spending by the consumer. Interestingly, while some orthodontic practices have joined the managed care programs, a majority of them realize neither increased patient load nor profit. Our data seem to indicate that orthodontic practices have not been successful in "cost containment" with their marketing, number of employees, computerization or inventory. Collectively, the results of this study suggest that success in an orthodontic office is primarily dependent on the practitioner's personality traits, rather than rigidly applied business principles.

Importance-satisfaction discrepancies are associated with health-related quality of life in five-year survivors of endocrine gastrointestinal tumours.

BACKGROUND: Little is known about the health-related-quality of life (HRQoL) of patients with endocrine gastrointestinal tumours. In this study, HRQoL was investigated in long-term survivors of endocrine GI tumours. PATIENTS AND METHODS: A questionnaire including the EORTC QLQ-C30 and ratings of importance of and satisfaction with a variety of HRQoL aspects was mailed to patients with carcinoid tumours (n = 64), or endocrine pancreatic tumours (EPT, n = 55). Median time since diagnosis was 120 months (range 60-360). The majority of patients (77 of 119) had ongoing treatment. RESULTS: The EORTC QLQ-C30 ratings suggest that in spite of a long disease duration and treatment, patients perceived their HRQoL as relatively good. There were no major differences in HRQoL ratings between patients with carcinoid tumours and those with EPT. Patients whose ratings of importance was higher than their ratings of satisfaction with a specific HRQoL aspect also evidenced a low HRQoL for that aspect. CONCLUSIONS: The results indicate that survivors of endocrine GI tumours enjoy a relatively good HRQoL and suggest that importance > satisfaction discrepancies identify patients with a low quality of life.

Violent events and security programs in California Emergency Departments before and after the 1993 Hospital Security Act.

INTRODUCTION: Health care workers have long been recognized as having a high risk of work-related assault. In response to a growing threat of violence in hospitals, California implemented the Hospital Security Act (AB508) in 1993. This study compares surveys of emergency nurses before and after implementation of AB508. METHODS: In 1990, the CAL/ENA surveyed emergency departments in California to enumerate violent events and describe security programs. Using the CAL/ENA membership directory, hospitals were resurveyed in 2000 to identify changes from the original survey. Surveys were mailed to the ED nurse manager or equivalent. Survey responses were anonymous. RESULTS: Most hospitals reported fewer violent episodes after the implementation of AB508. However, 32% of hospitals reported that 5 or more verbal threats occurred monthly, and 5% reported that 5 or more violent injuries occurred monthly. Overall, hospitals reported improvements in security programs. The most notable increase was in employee training, which rose from 34% to 95.6% of reporting hospitals. However, almost a quarter of hospitals reported not having general violence prevention policies, and many believed that security personnel were inadequate. DISCUSSION: Although results reported here cannot be directly attributed to AB508, the increase in security program components suggests that hospitals are responding positively to reduce violence. The high prevalence of threats and violent events reported indicates a persistent risk of violence against health care workers.

Swedish midwives' awareness of, attitudes to and use of selected research findings.

Members of a county division of the Midwives' Association of Sweden were surveyed to examine their awareness of, attitudes to and use of selected research findings. A total of 14 findings from research within the midwifery field were identified from midwives' dissertations and the journal Jordemodern using the criterion of physical availability. Questionnaires were mailed according to the membership list (n = 146). The response rate was 74% (n = 118). The results demonstrated that 75% of the midwives were aware of research findings, 65% were convinced of their usefulness and 63% used findings at least sometimes. According to the stages of Rogers' innovation-decision model the midwives were in the 'persuasion' stage, which is consistent with the result in Brett's 1987 study. The results indicate that research findings are used when midwives believe that the findings provide good care for mothers and babies. Even though the midwife in Sweden is considered to be an independent practitioner she is a member of a limiting social system. With regard to the interests influencing the health care system there is a need to examine the innovation-decision process from an organizational perspective to effectively improve the quality of care.

Patient Internet use for health information at three urban primary care clinics.

OBJECTIVE: To survey a cross section of patients presenting to three urban primary care clinics to understand online health information search behaviors. DESIGN AND ANALYSIS: At three urban primary care clinics affiliated with University at Buffalo, School of Medicine, 315 patients were interviewed. Interview questions included items on education, demographic information, employment, number of current prescriptions, insurance, online access, and specifics of health-searching behaviors. Chart review determined patient body mass index and number of chronic illnesses. Logistic regression and chi2 statistics were used to investigate the relationship between patient characteristics and the proportion of patients who use the Web for seeking health information. RESULTS: Approximately 53% of respondents reported using Web or e-mail in the past year and 68% (33% of total sample) of those who accessed the Web used it to search for health information. The two most commonly cited search areas included information about a physical illness and nutrition/fitness. Education and race significantly predicted online health-seeking behavior when considering all factors in the study. Many patients (22%) relied on friends and family to navigate the Web, and 45% of patients reported that the information that they sought was unrelated to their clinical visit. CONCLUSION: Current use of the Internet for health information was limited among more disadvantaged patient groups. More research is needed to examine the relationship between health-seeking behavior and patients' management of their health and well-being.

Percutaneous coronary intervention-associated nephropathy foreshadows increased risk of late adverse events in patients with normal baseline serum creatinine.

In patients with chronic renal insufficiency, further decline in renal function (DRF) after percutaneous coronary intervention (PCI) is accompanied not only by adverse in-hospital events but also by increased risk of mortality and myocardial infarction at 1 year. This analysis was undertaken to determine if patients with normal renal function who develop DRF after PCI have a comparable increase in risk of death and myocardial infarction at 1 year, and whether this risk is independent of in-hospital complications (death, myocardial infarction, urgent coronary artery bypass grafting). We performed a retrospective analysis of all patients from a single center who underwent successful PCI with no major in-hospital complications who had pre-PCI serum creatinine (SCr) </= 1.2 mg/dl and no history of renal insufficiency. One-year follow-up was obtained by mail or telephone. There were 5,967 consecutive patients who met the inclusion criteria. Of these, 208 (3.5%) developed DRF (an increase in SCr >/= 50% of baseline). They were more likely to be older, female, non-Caucasian, diabetic and/or hypertensive. They reported more prior cerebral or peripheral vascular events. They had undergone more complex PCI and were exposed to more radiographic contrast than the 96.5% who did not develop DRF. After adjustment for baseline variables, DRF remained an independent predictor of 1-year mortality, myocardial infarction, and target vessel revascularization. In patients without prior renal impairment, DRF post-PCI is rare but is associated with an increased risk of late adverse cardiac events similar to that in chronic renal insufficiency patients.

Increased plasma homocysteine after menopause.

Besides genetic defects in the enzymes involved in homocysteine metabolism and nutritional deficiencies in vitamin cofactors, sex steroid hormones may modulate plasma homocysteine levels. The post-menopausal state has been found to be associated with higher plasma homocysteine levels, but data are inconsistent and studies published so far did not adjust for age, which is an important confounding factor in studying the effect of menopause. In the present study total plasma homocysteine levels were measured in a meticulously selected population in which the contrast in estrogen status between pre- and postmenopausal women of the same age was maximized. The study comprised 93 premenopausal and 93 postmenopausal women of similar age (range 43-55 years). Women were selected from respondents to a mailed questionnaire on menopause, which was sent to all women aged 40-60 years in the Dutch town of Zoetermeer (n = 12675). Postmenopausal women who were at least three years after menopause or whose menses had stopped naturally before age 48 were age-matched with premenopausal women with regular menses and without menopausal complaints. Plasma homocysteine levels in the fasting state were related to menopausal status; the age-adjusted geometric mean was 10.7 micromol/l in premenopausal and 11.5 micromol/l in postmenopausal women (difference of 7%, 95% confidence interval 0.3-14%, P = 0.04). Additional adjustment for plasma creatinine, body mass index, smoking habit (yes, no) and alcohol intake did not influence this difference. The results of this population-based study indicate that plasma homocysteine is affected by menopause.

Do normal findings at biliary endoscopic ultrasonography obviate the need for endoscopic retrograde cholangiography in patients with suspicion of common bile duct stone? A prospective follow-up study of 238 patients.

BACKGROUND AND STUDY AIMS: Biliary endoscopic ultrasonography (EUS) and endoscopic retrograde cholangiography (ERC) are equally accurate for the diagnosis of common bile duct (CBD) stone. The aim of this prospective 1-year follow-up study was to determine whether normal findings at initial EUS obviated the need for ERC. PATIENTS AND METHODS: During a 17-month period, all patients referred for biliary EUS because of suspicion of CBD stone, in whom EUS findings were normal were included in the study. Early (1-month) and late (1-year) follow-up details were obtained by mail or telephone. The clinical course and need for ERC were recorded. RESULTS: 238 patients were enrolled. During follow-up, 59 (25 %) patients underwent cholecystectomy, with (n=31) or without (n=28) cholangiography, and 30 patients underwent ERC (13 %). CBD stone was found in 14 (6 %) patients. Of these 30 patients, ERC was done in 15 cases in the first week after EUS, because of persistent suspicion of a CBD stone which was found in 10 patients. The 15 late ERC procedures (carried out more than 1 week after EUS) revealed only one CBD stone. The negative predictive value of EUS for the diagnosis of CBD stones was 95.4 %. CONCLUSIONS: Patients with suspicion of CBD stones but normal EUS findings have a low risk of needing ERC in a 1-year period.

How effective is email communication for patients requiring elective surgery?

BACKGROUND: Patients increasingly use the Internet for communication as well as to obtain information, but there are few published reports on either the utilization or effectiveness of email as a means of communication between patient and surgeon. The aim of the present study is to examine the effectiveness of email communication by patients prior to undergoing elective surgery. METHODS: This is a retrospective cohort study of 306 patients undergoing thyroid or parathyroid surgery at a tertiary referral centre who had been provided with an information sheet promoting email communication compared to 352 patients in a control group who had not been provided with the same information. RESULTS: In the study group 50 of 306 patients (16%) utilized email communication. There was a statistically significant difference (P = 0.0004) in the age distribution between those who did (mean: 46.2, 95% confidence interval (CI): 42.0-50.4) and those who did not (mean: 54.6, 95%CI: 52.7-56.4) utilize emails, with the email users representing a younger population. In the control group, only 10 of 352 (3%) used email, a significantly lower percentage (P = 0.0001) than in the study group. A total of 101 emails were sent by 50 patients in the study group. Of these, the majority did so only once (n = 28-56%), with one patient sending seven separate emails. Most emails sent focused on only one issue, but some patients raised multiple issues with the most being seven issues in a single email. CONCLUSIONS: Despite concerns about potential medicolegal issues and other disadvantages, routine email communication between physician and patient provides an effective means of communication for patients undergoing elective surgery.

Recruitment methods for community-based screening for diabetic retinopathy.

Regular screening of all people with diabetes is the most efficient and cost-effective way to detect early stages of diabetic retinopathy so that laser treatment can be performed at the optimal time. A major aim of the Program for the Early Detection of Diabetic Retinopathy was to increase compliance with guidelines for screening for diabetic retinopathy. This community-based screening program used non-mydriatic retinal photography and was initiated in four areas of Victoria, Australia from 1996-1998. Recruitment strategies included targeted mail-outs, provision of the program brochure in English and the main languages spoken in the areas and media promotion in ethnic newspapers and on ethnic radio stations. In Victoria, only 55% of the population with diabetes currently access eye care services at the recommended intervals. This program was able to increase compliance with guidelines to 70% among people with diabetes that had not had a recent eye examination. A total of 1,197 people with diabetes were screened for diabetic retinopathy. Of the 1,197 people who were screened, 620 (15% of the estimated number of people with diabetes) had not had their eyes examined in the past two years. This pilot study identified strategies to encourage people with diabetes to have their eyes examined at the recommended intervals.

Are international medical graduates a factor in residency program selection? A survey of fourth-year medical students.

PURPOSE: To examine whether the proportions of international medical graduates (IMGs) enrolled in certain residency programs would affect students' selection of those programs during the match, and to determine the importance of this factor relative to other established program-selection factors. METHOD: A sample of 702 fourth-year students at 18 geographically diverse U.S. medical schools during March and April of 1994 were mailed a confidential survey asking them to rank and rate hypothetical programs and to rate the importance of selected characteristics in their rankings of programs during the match. The students were asked to rank five hypothetical programs described by nine characteristics. One-third of the students received additional information about the programs' reputations; another third, information about the percentages of IMGs in the programs. The control group received no information about these two characteristics. Comparisons of the mean rankings and ratings of the five programs between the control and intervention groups were made using the Mann-Wilcoxon rank-comparison statistical test. RESULTS: The response rate was 44%, with 291 survey forms returned completed (45 were returned due to no forwarding address). When the rankings and ratings of the control and intervention groups were compared, the programs with higher numbers of IMGs worsened significantly in rank and rating (p < .001 for both), whereas the programs with better reputations improved in rank (p < .001) and rating (p < .005). CONCLUSION: The results suggest that the proportion of IMGs in a residency program is a significant factor in program selection and is as important as previously established factors such as program reputation. Students, however, do not acknowledge the importance of this factor. Program directors and governing bodies may want to consider these findings when evaluating the impact and distribution of IMGs in U.S. training programs.

Contributions of maternal identity and lifestyle to young children's adjustment.

Early child behavior problems have been related to later child adjustment. Therefore, it is important to study factors, such as maternal characteristics, which may affect early child behavior. Existing science stresses the import of maternal identity formation as a key aspect of the early mother-child relationship; however, recent evidence also shows that mothers' health-related lifestyles are salient to preschool children's healthy adjustment. The relative contributions of these two influences on children's behavioral adjustment were compared in a longitudinal mail study of new mothers. The sample consisted of two cohorts of mothers (6 or 12 months postpartum at recruitment) systematically selected (every third name) from published birth announcements in a midwestern newspaper. Maternal identity and lifestyle were both measured when children were 6 to 12 months and were used to predict child behavioral problems 2 years later (N = 122). Using path analysis, the influence of maternal identity and lifestyle on child behavior problems was tested within one model with maternal age, education, family income, and social desirability statistically controlled. The model provided an acceptable fit to the data. The hypothesis that maternal identity would be related to child behavior problems was not supported; however, maternal lifestyle was significantly related to child behavior problems. These findings support the relationship between the mother's health-related lifestyle and her young child's adjustment.

Prostate cancer early detection practices among men with a family history of disease.

OBJECTIVES: Genetic studies of familial prostate cancer, which is often asymptomatic until advanced stages, rely on correct designation of affection status. In this pilot study, we set out to determine the proportion of unaffected men whose families are participating in a study of hereditary prostate cancer who have been tested for prostate cancer with serum prostate-specific antigen (PSA) measurement and digital rectal examination (DRE). METHODS: Participants were identified from the University of Michigan Prostate Cancer Genetics Project, a family-based study of inherited prostate cancer susceptibility. Of the 141 eligible affected and unaffected sons of men with prostate cancer, 124 (88%) completed a mailed questionnaire regarding serum PSA testing and DRE history. RESULTS: Among unaffected men, 95% reported ever having had a PSA test, and 97% ever having had a DRE, with most initial tests occurring between the ages of 40 and 60 years. No significant difference in the mean age at first PSA test or DRE between the affected and unaffected men was observed. Affected men were significantly more likely than unaffected men to have a first PSA level greater than 2.5 ng/mL (P = 0.006), but not greater than 4.0 ng/mL (P = 0.614). CONCLUSIONS: Most men with a family history of prostate cancer are undergoing early detection testing. The differences in early detection testing practices do not appear to account for the difference in affection status among the sons of men with prostate cancer.

Readmission of patients after coronary artery bypass graft surgery.

OBJECTIVE: To assess rates, reasons, and predictors of hospital readmission after coronary artery bypass grafting (CABG). METHODS: In this prospective, descriptive, correlational study, 124 subjects responded to a mailed questionnaire 6 weeks after undergoing CABG at Yale New Haven Hospital. RESULTS: The sample was 79% male, 94% white, and had a mean age of 66 +/- 10 years and a mean length of stay of 5.7 +/- 1.8 days. A total of 14.5% had unplanned cardiac-related readmissions (44% to their community hospital). Chest pain with or without shortness of breath was the primary reason for readmission (33%), followed by incisional problems (17%) and analgesic reactions (17%). Logistic regression analysis, based on bivariate analyses, revealed that female sex (odds ratio 4.7; 95% confidence interval, 1. 5-14.6; P =.007) and obesity (odds ratio 3.7; 95% confidence interval, 1.2-11.6; P =.026) predicted hospital readmission. CONCLUSIONS: Effective follow-up, with particular focus on women and the obese, may decrease readmissions. (Heart Lung((R)) 1999;28:243-50).

Nutrition and other risk factors for renal cell carcinoma in postmenopausal women.

Among 35,192 postmenopausal, predominantly white women in Iowa age 55-69 years and free of cancer, we collected baseline history, dietary information, and anthropometric data by mail in 1986. We ascertained the 8-year incidence (62 new cases) of renal cell carcinoma using the Iowa Surveillance, Epidemiology, and End Results (SEER) register, the National Death Index, and mail follow-up. Risk factors for renal cell carcinoma included increasing age, increasing weight (either current, maximum adult weight, or weight at ages 18, 30, or 50 years), greater waist-to-hip ratio, and a history of blood transfusion. Total dietary calcium was associated independently with a reduced risk of renal cell carcinoma. No other dietary micro- or macronutrients or food groups were predictive of the development of renal cell carcinoma. Other previously identified risk factors were not confirmed: most notably, there was no increased risk from a history of hypertension, after adjustment for diuretic use. History of ever-use of diuretics was associated with a twofold increased risk of renal cancer, although the strength of association was markedly reduced after adjustment for age, weight, waist-to-hip ratio, and calcium intake.

Prevalence of assault and perception of risk of assault in urban public service employment settings.

This study describes the prevalence and correlates of physical assaults, threats of assault, and workers' perceptions of safety in selected urban employment settings. Questionnaires were mailed to a random sample of 1,763 persons working at various jobs and sites throughout Los Angeles County. Workers were asked to describe their work environments, their perceptions of personal safety at work, and physical assaults and threats they had experienced. Three percent of the respondents reported being assaulted within the previous year and 14% reported being threatened within the previous 30 days. Younger workers, more educated workers, and those who worked with clients or patients were more likely to report assaults. Approximately one third of those who reported threats or assaults described the perpetrator(s) as clients, patients, or persons in legal custody, and one third described the perpetrator(s) as co-workers or supervisors. Fifty-two percent of the workers reported being concerned about their safety at work.

Physician-assisted suicide in Connecticut: physicians' attitudes and experiences.

OBJECTIVE: This study examined aspects of physician attitudes toward physician-assisted suicide (PAS) not fully examined to date: evaluation of risks related to PAS, particularly the presence of depression, and the influence of religious and professionally-based values. DESIGN: Anonymous, self-administered mailed questionnaire using Dillman methodology. PARTICIPANTS: Targeted sample of physicians licensed by the Connecticut Department of Public Health in 1997 (n = 2,805 completed surveys; 40% response rate). DATA INCLUDE: Physician and patient characteristics, attitudes toward physician assisted suicide, and confidence in treating depression. RESULTS: Religious affiliation, religiosity, ethnicity and medical specialty were strongly associated with views on PAS. Seven percent of respondents had been asked to write a lethal prescription during the past year, 15% of whom (n = 24) had complied with at least one request. CONCLUSIONS: Most respondents expressed concern regarding certain risks associated with PAS, including movement toward involuntary euthanasia and the influence of undetected depression. Findings raise practical issues to be addressed through statutory or professional safeguards if PAS were to be legalized.

Using the Cancer Rehabilitation Questionnaire in patients with colorectal cancer.

This article describes the development and testing of the Cancer Rehabilitation Questionnaire (CRQ) in patients with colorectal cancer. A descriptive, correlational survey was conducted in a sample of patients with colon or rectal cancer who received care at an outpatient cancer clinic at a large, northeastern U.S. academic medical center. Patients were identified from the Tumor Registry (N = 327) and received a mailed questionnaire. One hundred and three patients with colorectal cancer completed the demographic questionnaire, the CRQ developed by the investigators, and the Quality of Life Index (QLI). Significant differences were found between individuals with colon cancer and individuals with rectal cancer on the total CRQ (p < .005) and the physical, future orientation, and role-relationship subscales. For the QLI, significantly lower scores were reported on the family subscale for patients with rectal cancer in comparison with those with colon cancer. More attention to rehabilitation issues and quality of life is required across the trajectory of the cancer experience. With the increasing incidence of colorectal cancer, nurses in rehabilitation practice must address the issues affecting patients with this disease as they progress from diagnosis to treatment and rehabilitation.
