Reliability of the VCM1 Questionnaire when administered by post and by telephone.

PURPOSE: To assess the reliability of different methods of administration of the VCM1 vision-related quality-of-life questionnaire by: a) comparing responses obtained by post to responses obtained in a research clinic and b) comparing responses obtained by telephone to responses obtained in a research clinic. METHOD: Questionnaire responses given in advance by post (96 subjects) or by telephone (92 subjects) were compared to those subsequently given at a visit to a research clinic. The questionnaire included the VCM1 and two other questions commonly used in surveys of visual impairment (reading small print and recognising a face across the street). RESULTS: Similar levels of vision-related quality-of-life (VR-QOL) impairment were reported by post and in the research clinic. However, the participants in the telephone test group reported less VR-QOL impairment by telephone than they subsequently reported in the clinic (P = 0.0001). The mean score difference between telephone and clinic administration was 3.2% of the VCM1 questionnaire scale. Lower social class (P = 0.002) and increasing duration of interview (P = 0.003) were associated with a tendency to under-report VR-QOL impairment by telephone. Interference with reading small print (P = 0.0001) and recognising a face across the street (P = 0.0001) were also under-reported by telephone. CONCLUSIONS: Telephone interviewing caused a general bias towards under-reporting of visual problems which was not confined to the VCM1. Care is required when planning outcome studies and questionnaire surveys to ensure that different methods of questionnaire administration produce comparable results.

Cellular telephone use and cancer risk: update of a nationwide Danish cohort.

BACKGROUND: The widespread use of cellular telephones has heightened concerns about possible adverse health effects. The objective of this study was to investigate cancer risk among Danish cellular telephone users who were followed for up to 21 years. METHODS: This study is an extended follow-up of a large nationwide cohort of 420,095 persons whose first cellular telephone subscription was between 1982 and 1995 and who were followed through 2002 for cancer incidence. Standardized incidence ratios (SIRs) were calculated by dividing the number of observed cancer cases in the cohort by the number expected in the Danish population. RESULTS: A total of 14,249 cancers were observed (SIR = 0.95; 95% confidence interval [CI] = 0.93 to 0.97) for men and women combined. Cellular telephone use was not associated with increased risk for brain tumors (SIR = 0.97), acoustic neuromas (SIR = 0.73), salivary gland tumors (SIR = 0.77), eye tumors (SIR = 0.96), or leukemias (SIR = 1.00). Among long-term subscribers of 10 years or more, cellular telephone use was not associated with increased risk for brain tumors (SIR = 0.66, 95% CI = 0.44 to 0.95), and there was no trend with time since first subscription. The risk for smoking-related cancers was decreased among men (SIR = 0.88, 95% CI = 0.86 to 0.91) but increased among women (SIR = 1.11, 95% CI = 1.02 to 1.21). Additional data on income and smoking prevalence, primarily among men, indicated that cellular telephone users who started subscriptions in the mid-1980s appeared to have a higher income and to smoke less than the general population. CONCLUSIONS: We found no evidence for an association between tumor risk and cellular telephone use among either short-term or long-term users. Moreover, the narrow confidence intervals provide evidence that any large association of risk of cancer and cellular telephone use can be excluded.

Satisfaction with telephone advice from an accident and emergency department: identifying areas for service improvement.

OBJECTIVES: Members of the public often telephone general practice, accident and emergency departments, and other health services for advice. However, satisfaction related to telephone consultation has received relatively little attention. This study aimed to describe the views of callers to an accident and emergency department who expressed any element of dissatisfaction about their telephone consultation. This was part of a larger study intended to help identify areas for service improvement. METHODS: A telephone consultation record form was used to document details of advice calls made to the accident and emergency department over a three month period. Callers who provided a telephone number were followed up within 72 hours. The interviews were tape recorded, transcribed, and explored using content analysis for emerging themes related to dissatisfaction. RESULTS: 203 callers were contacted within 72 hours of their call, of which 197 (97%) agreed to participate. 11 (5.6%) expressed global dissatisfaction, and a further 34 (17%) callers expressed at least one element of dissatisfaction at some point during the interview. Sources of dissatisfaction fell into four broad categories, each of which included more specific aspects of dissatisfaction: 36 (80%) callers were dissatisfied with advice issues, 31 (69%) with process aspects, such as the interpersonal skills of the staff member who took the call, 23 (51%) due to lack of acknowledgement of physical or emotional needs, and 11 (24%) due to access problems. CONCLUSIONS: This study supports the findings of other work and identifies three issues for particular consideration in improving the practice of telephone consultation: (a) training of health professionals at both undergraduate and specialist levels should cover telephone communication skills, (b) specific attention needs to be given to ensuring that the information and advice given over the phone is reliable and consistent, and (c) organisational change is required, including the introduction of departmental policies for telephone advice which should become the subject of regular audit.

Cellular telephone interference with medical equipment.

OBJECTIVE: To assess the potential electromagnetic interference (EMI) effects that new or current-generation cellular telephones have on medical devices. MATERIAL AND METHODS: For this study, performed at the Mayo Clinic in Rochester, Minn, between March 9, 2004, and April 24, 2004, we tested 16 different medical devices with 6 cellular telephones to assess the potential for EMI. Two of the medical devices were tested with both new and old interface modules. The 6 cellular telephones chosen represent the different cellular technology protocols in use: Code Division Multiple Access (2 models), Global System for Mobile communications, Integrated Digital Enhanced Network, Time Division Multiple Access, and analog. The cellular telephones were tested when operating at or near their maximum power output. The medical devices, connected to clinical simulators during testing, were monitored by observing the device displays and alarms. RESULTS: Of 510 tests performed, the incidence of clinically important interference was 1.2%; EMI was Induced in 108 tests (21.2%). Interference occurred in 7 (44%) of the 16 devices tested. CONCLUSIONS: Cellular telephones can interfere with medical equipment. Technology changes in both cellular telephones and medical equipment may continue to mitigate or may worsen clinically relevant interference. Compared with cellular telephones tested in previous studies, those currently in use must be closer to medical devices before any interference is noticed. However, periodic testing of cellular telephones to determine their effects on medical equipment will be required.

Safe use of cellular telephones in hospitals: fundamental principles and case studies.

Many industries and individuals have embraced cellular telephones. They provide mobile, synchronous communication, which could hypothetically increase the efficiency and safety of inpatient healthcare. However, reports of early analog cellular telephones interfering with critical life-support machines had led many hospitals to strictly prohibit cellular telephones. A literature search revealed that individual hospitals now are allowing cellular telephone use with various policies to prevent electromagnetic interference with medical devices. The fundamental principles underlying electromagnetic interference are immunity, frequency, modulation technology, distance, and power Electromagnetic interference risk mitigation methods based on these principles have been successfully implemented. In one case study, a minimum distance between cellular telephones and medical devices is maintained, with restrictions in critical areas. In another case study, cellular telephone coverage is augmented to automatically control the power of the cellular telephone. While no uniform safety standard yet exists, cellular telephones can be safely used in hospitals when their use is managed carefully.

Payment for telephone care.

Telephone care in pediatrics requires medical judgment, is associated with practice expense and medical liability risk, and can often substitute for more costly face-to-face care. Despite this, physicians are infrequently paid by patients or third-party payors for medical services provided by telephone. As the costs of maintaining a practice continue to increase, pediatricians are increasingly seeking payment for the time and work involved in telephone care. This statement reviews the role of telephone care in pediatric practice, the current state of payment for telephone care, and the practical issues associated with charging for telephone care services, a service traditionally provided gratis to patients and families. Specific recommendations are presented for appropriate documenting, reporting, and billing for telephone care services.

Telephone subsidy: an effective incentive for successful participation in home memory monitor study.

CONTEXT: The Collaborative Home Infant Monitoring Evaluation (CHIME) study enrolled healthy term infants and 3 groups of infants considered to be at increased risk for sudden infant death syndrome to evaluate apnea and bradycardia events in the home. Mother-infant pairs without a telephone were ineligible for enrollment. OBJECTIVE: To determine whether mother-infant pairs who were offered a telephone subsidy would agree to enroll in CHIME and achieve protocol compliance rates comparable with those of matched subjects able to afford telephones. DESIGN: Thirty-one telephone subsidy subjects were retrospectively compared with 55 control subjects matched for study group, site, birth weight, and maternal race, age, and education. SETTING: Collaborative Home Infant Monitoring Evaluation clinical research centers in Honolulu, Hawaii, and Toledo, Ohio. INTERVENTION: Provision of telephone subsidy to otherwise eligible enrollees for CHIME. MAIN OUTCOME MEASURES: Frequency of compliance with protocol requirements for follow-up evaluations and for extent of home monitoring. RESULTS: Subsidy subjects achieved protocol completion rates that were comparable with those of control subjects, for developmental assessments at 56 and 92 weeks postconceptional age (PCA), and for the polysomnogram. Unexpectedly, however, subsidy subjects were more likely to have a developmental assessment at 44 weeks PCA (P =.02), as well as a cry analysis (P =.04). They were also more likely to use the CHIME home monitor for more hours during weeks 2 through 5 (P =.004), have a higher percentage using the monitor for 10 or more hours per week during weeks 2 through 5 (P =.009), and have a higher total number of days of monitor use throughout 6 months (P <.001). Mean cost of the subsidy was $3.25 per day of monitor use, and monitor use per day was directly related to total cost of the subsidy (P =.02). CONCLUSIONS: Telephone subsidy is an effective financial incentive. At least within the context of the CHIME study, telephone subsidy enhanced access to health care, and in some categories it resulted in enhanced protocol compliance.

An assessment of pediatric after-hours telephone care: a 1-year experience.

BACKGROUND: Pediatric after-hours telephone triage by call center nurses is an important part of pediatric health care provision. OBJECTIVES: To use a computerized database including the after-hours telephone calls for 90% of the pediatricians in Colorado to examine: (1) the epidemiology of after-hours calls during a 1-year period including the volume, seasonality, and timing of after-hours calls, the age of the patients, the presenting complaint, the triage dispositions, and mean rates of calls per pediatrician; (2) the process of care measures at the call center, including waiting times for nurse telephone call-backs, the length of triage calls, and how these factors varied by season; and (3) the frequency and content of calls requesting information but not requiring triage. DESIGN: Descriptive study. SETTING AND PARTICIPANTS: All telephone calls from the After-Hours Telephone Care Program, Denver, Colo, received between June 21, 1999, and June 20, 2000, were retrieved from a computerized database and categorized by age, season, triage disposition, and algorithm. MAIN OUTCOME MEASURES: The volume, seasonality, timing, age distribution, algorithms used, and triage dispositions of after-hours calls. The reasons for calls requesting information. RESULTS: During the 1-year period 141 922 calls were returned by the call center. Of the total calls, 88% were for a clinical illness; 5%, for information or advice; 5%, for calls in which the parent could not be recontacted; 1%, for duplicate calls, and 1%, for miscellaneous reasons. Listed in rank order for the year, the 10 most common algorithms used for illness calls were vomiting, colds, cough, earache, sore throat, fever, diarrhea, croup, head trauma, and eye infection. Of illness calls, 21% of callers were told to go in for urgent evaluation, 30% were told to contact their primary care physician either the next day or at a later time, 45% were given home care instructions, and 4% were referred to call the on-call physician. CONCLUSIONS: This study describes the epidemiology of after-hours telephone calls regarding children in 90% of the private practices in Colorado. Data provided are useful in guiding the planning of health care provision, providing staffing of after-hours facilities, and planning for the educational training of telephone care staff. They also highlight opportunities for patient education that might decrease unnecessary after-hours calls.

Asymptomatic telephone ECG transmissions as an outpatient surveillance system of ventricular arrhythmias: relationship to quantitative ambulatory ECG recordings.

Although ambulatory ECG recordings provide quantitative information in the follow-up of patients with ventricular arrhythmias, they are performed infrequently, potentially missing serious arrhythmias in the unmonitored periods. Telephone ECG systems offer "real-time" ECG information, theoretically functioning as an arrhythmia surveillance system. Thus we incorporated frequent telephone ECG transmissions in two antiarrhythmic drug protocols. The first investigation was designed to show the relationship of telephone and ambulatory ECGs in patients with frequent ventricular tachycardia (VT). The second protocol selected patients with "nonlife-threatening" frequent premature ventricular complexes (PVCs) in whom a second placebo period was instituted to simulate the clinical situation of asymptomatic arrhythmia increase. In both drug trials there was a strong linear relationship between the log-transformed PVC counts of telephone ECG and concomitant PVC, couplet, and VT frequencies on ambulatory ECG. In the VT population, greater than or equal to 1 PVC on telephone ECG reflected the presence of VT on ambulatory ECG (sensitivity 87%; specificity 77%). In the second study, telephone ECG transmissions with PVCs on three consecutive transmissions reflected the change from less than or equal to 10 PVCs/hour to greater than or equal to 40 PVCs/hour on ambulatory ECG within 48 hours. These data support the concept that daily surveillance by means of telephone ECG provides arrhythmia information of qualitative clinical relevance.

The influence of a structured telephone call on orthodontic pain and anxiety.

INTRODUCTION: This purpose of this study was to examine the effects of a structured telephone call after orthodontic appliance placement on self-reported pain and anxiety. METHODS: One hundred-fifty orthodontic patients were randomly assigned to 1 of 3 groups and matched for age, sex, and ethnicity. The subjects completed baseline questionnaires to assess their levels of pain (on a 100-mm visual analog scale) and anxiety (Spielberger's State-Trait Anxiety Inventory) before orthodontic treatment. After the initial archwires were placed, all subjects completed the pain questionnaire and state-anxiety inventory at the same time daily for 1 week. One group also received a structured telephone call demonstrating care and reassurance; the second group received an attention-only telephone call, thanking them for participating in the study; the third group served as a control. RESULTS: Although both telephone groups reported significantly less pain (P = .005) and state-anxiety (P = .033) than the control group, there was no difference between the 2 telephone groups (P > .12 for pain; P > .81 for state-anxiety). CONCLUSIONS: A telephone call from a health-care provider reduced patients' self-reported pain and anxiety; the content of the telephone call was not important.

Evaluating the utility and accuracy of a reverse telephone directory to identify the location of survey respondents.

PURPOSE: To investigate the utility and positional accuracy of a reverse telephone directory to enhance geocoding using self-reported street addresses. METHODS: This cross-sectional study used 2001 self-reported survey data from 2636 participants in three Missouri areas. When available, street addresses were appended to participant telephone numbers using a reverse telephone directory. The odds of finding a telephone number in the reverse directory and the positional accuracy between self-reported addresses and those obtained from the reverse directory were calculated. We also determined the quality of self-reported address information and that obtained by means of the reverse telephone directory. RESULTS: Rural respondents, younger respondents, women, African Americans, and respondents with less than a high school education were less likely to have their telephone number present in the reverse directory. Using the reverse directory increased the overall percentage of respondents whose addresses were geocoded from 51.5% to 72.0%. Eighty-one percent of addresses were geocoded to the same US Census Block Group and 89% were geocoded to the same Census Tract as the self-reported addresses. CONCLUSIONS: The street address of survey participants obtained through the reverse directory can be used to augment the unknown location of telephone survey respondents but specific groups of people are less likely to be found in the directory.

The effect of a scheduled telephone intervention on outcome after moderate to severe traumatic brain injury: a randomized trial.

OBJECTIVE: To measure the effectiveness of a scheduled telephone intervention offering counseling and education to people with traumatic brain injury (TBI) on behavioral outcomes compared with standard follow-up at 1 year postinjury. DESIGN: Two-group randomized, prospective clinical trial throughout the first year after injury. SETTING: Subjects' homes via telephone in an urban-rural catchment area from a level I trauma center. PARTICIPANTS: Subjects (N=171; age range, 18-70 y) with a primary diagnosis of TBI who were discharged from an acute rehabilitation unit. They were randomly assigned to the telephone intervention (n=85) or to standard follow-up (n=86) groups at discharge. Of these, 79 participated in the intervention and completed the outcome assessment (3 withdrew; 3 were lost to follow-up), and 78 participated in usual care and completed the outcome assessment (8 were lost to follow-up). INTERVENTIONS: Subjects were randomly assigned to receive telephone calls at 2 and 4 weeks and 2, 3, 5, 7, and 9 months after discharge. The calls consisted of brief motivational interviewing, counseling, and education, plus facilitating usual care or usual care alone through follow-up appointments and therapy prescriptions. MAIN OUTCOME MEASURES: A composite outcome was used as the primary endpoint on an intent-to-treat basis. Secondary analyses were conducted with individual measures, including the FIM instrument, Disability Rating Scale, Community Integration Questionnaire, Neurobehavioral Functioning Inventory, Functional Status Examination, Glasgow Outcome Scale-Extended, Medical Outcomes Study 36-Item Short-Form Health Survey, Brief Symptom Inventory, EuroQol, and Modified Perceived Quality of Life scale. The primary analysis was a blocked Mann-Whitney U test. RESULTS: At 1-year follow-up, those who had received scheduled telephone intervention fared significantly better on the primary composite outcome index ( P =.002). In addition, this group fared better on specific composites such as functional status ( P =.003) and quality of well-being ( P =.006). There were no significant differences on vocational status ( P =.08) or community integration status ( P =.13). CONCLUSIONS: Scheduled telephone counseling and education resulted in improved overall outcome, particularly for functional status and quality of well-being, when compared with usual outpatient care. Telephone counseling shows promise as a low-cost, widely available rehabilitation intervention for TBI.

Telephone first post-intervention follow-up for men who have had radical radiotherapy to the prostate: evaluation of a novel service delivery approach.

The increasing prevalence of prostate cancer places pressure on services, leading to questions about how best to configure services, so as to maintain quality and best utilise the skills of the multi-disciplinary team. There have been positive evaluations of specialist nursing roles, nurse-led service provision and telephone consultations, leading us to consider whether telephone follow-up led by a specialist nurse might be an acceptable alternative to traditional follow-up in hospital-based out-patient clinics for patients receiving radical radiotherapy for prostate cancer. Thirty-six men were included in a pilot introduction of telephone follow-up, evaluated via a questionnaire survey. The evaluation explored patients' satisfaction with practical arrangements; satisfaction with the nurse; acceptability of telephone follow-up and acceptability of this being nurse-led. Patients reported high levels of satisfaction with practical arrangements. Thirty-five patients considered the nurse to be knowledgeable and found nurse-led care acceptable. Only one patient was unhappy with telephone follow-up, whilst 27 were "very happy". Only one patient felt that telephone follow-up was poorer than traditional follow-up, whilst 27 found it "as good" and three "better". Particular advantages were reported in terms of convenience and time savings. Telephone follow-up appears to have potential for this patient group and merits wider, research-based consideration.

Telephone-based counseling improves dietary fat, fruit, and vegetable consumption: a best-evidence synthesis.

Eating more fruits/vegetables and less dietary fat rank among the most important nutrition recommendations for health improvement. Telephone counseling is an increasingly popular means of delivering support for diet modification. Using a best-evidence synthesis, the purpose of this review was to assess the effectiveness of telephone-based counseling on improving dietary fat, fruit, and vegetable consumption for adults. Online databases and article bibliographies were searched to produce relevant randomized-controlled trials published during the past 5 years. Nine studies were ultimately included and the weight of the evidence indicated that telephone-based counseling promotes significantly greater improvements in fruit/vegetable consumption (median effect size=0.41) and dietary fat intake (median effect size=0.22) relative to usual care. Improvements were especially pronounced among women with (or at high risk for developing) cancer. In some studies, telephone-based counseling was also associated with greater improvement in blood lipid levels and weight. Based on these findings, several design considerations (eg, population focus, counseling intensity) for program managers are proposed. Telephone-based counseling was found to be a moderately effective intervention, but there are not enough studies yet to draw conclusions on other research questions, such as how advantageous telephone-based counseling is over traditional forms of dietary counseling. At present, telephone-based counseling may best be used as a complement to clinical care and a means to broaden the outreach of nutrition services.

[Speech discrimination through telephone in patients implanted with a Combi 40+].

OBJECTIVE: To assess speech discrimination through line and mobile telephone in cochlear implanted patients. MATERIAL AND METHODS: Eighteen patients implanted with a Combi 40+ went through different speech discrimination tests with a line telephone and three mobile telephones, in quiet and noisy environment. RESULTS: Mean scores for telephonic speech discrimination were 84-92% using CID sentences, 27-58% using bisyllabic words in quiet environment and 15-41% using bisyllabic words in noisy environment. Among the mobile telephones tested, the Siemens M55 reached the best scores. CONCLUSIONS: Telephonic speech discrimination is achieved by a significant number of cochlear implanted patients. Certain mobile telephone models appear to be more advisable for these patients.

In-person vs telephone-administered multiple-pass 24-hour recalls in women: validation with doubly labeled water.

OBJECTIVE: To determine the accuracy of energy intakes estimated with the multiple-pass 24-hour recall method in women by conducting in-person and telephone interviews. Doubly labeled water measurements of total energy expenditure were used for validation. SUBJECTS: Thirty-five weight-stable women (mean age = 30 years, range = 19 to 46 years) participated. DESIGN: Total energy expenditure was measured over a 14-day period using the doubly labeled water method. During this time, 4 multiple-pass 24-hour recalls were obtained from the women (2 in-person, 2 by telephone) who were provided 2-dimensional food models to estimate portion sizes. The Food Intake Analysis System was used to analyze recall data. STATISTICAL ANALYSES: Paired t tests were conducted to examine differences between energy intake estimated from the telephone and in-person interviews. Agreement between the energy intake estimates from the telephone recalls and the in-person recalls was assessed using the technique of Bland and Altman. Paired t tests were used to compare energy intake estimated from the telephone and in-person recalls to total energy expenditure. RESULTS: No significant difference in mean daily energy intake was found between the telephone (2,253 +/- 688 kcal) and in-person (2,173 +/- 656 kcal) interviews (P = .36). However, the mean energy intake from each interview method was significantly lower than total energy expenditure (2,644 +/- 503 kcal) (P = .006 and .001, respectively). APPLICATIONS/CONCLUSIONS: Underreporting of energy intake was widespread in the sample. Although the multiple-pass 24-hour recall method did not generate a group measure of energy intake that was accurate or unbiased, the telephone-administered multiple-pass 24-hour recall was just as effective in estimating energy intake as the recall administered in-person. Dietetics professionals should be aware of the pervasive and serious problem of under-reporting of self-reported food intakes.

The use of telephone interview methodology to obtain 24-hour dietary recalls.

OBJECTIVE: To compare 24-hour dietary recalls collected over the telephone to in-person recalls collected in the 1994-1996 Continuing Survey of Food Intakes by Individuals (CSFII). DESIGN: Trained interviewers collected 24-hour dietary recalls over the telephone using the multiple-pass approach. These results were compared to in-person interviews from a pooled subsample of CSFII respondents. SUBJECTS/SETTING: List-assisted random-digit dialing was used to identify 700 women between the ages of 20 and 49 years. One eligible woman per household was selected to participate. STATISTICAL ANALYSES: Approximate t tests to examine differences in average nutrient and energy intakes were conducted on weighted data. RESULTS: The reported intakes of most nutrients in the current 24-hour dietary recalls collected over the telephone were significantly higher than those reported in the 1994 and 1995 CSFII, but there were no significant differences between the telephone survey and 1996 CSFII results. The 24-hour dietary recalls collected over the telephone yielded consistently greater mean nutrient intake per respondent compared with a comparable pooled subsample from the 1994, 1995, and 1996 CSFII. Generally, no significant differences were found in the food group data between the telephone survey and the CSFII survey. Mean dietary intakes reported by the comparable CSFII subsample increased from 1994 to 1996. APPLICATIONS: Collecting 24-hour dietary recalls over the telephone is a practical and valid data collection tool for use in national food consumption surveys.

Assessment of vulvovaginal complaints: accuracy of telephone triage and in-office diagnosis.

OBJECTIVE: To examine the agreement between telephone and office management of vulvovaginal complaints and to assess the accuracy of diagnosis of vulvovaginitis. METHODS: Prospective structured telephone nurse interviews of all patients with vulvovaginal complaints who called the Kaiser Permanente Telephone Call Center were conducted. Patients were appointed to a physician, nurse midwife, or physician's assistant for office evaluation. Both groups (nurses and practitioners) made independent diagnosis and treatment decisions. kappa coefficients were used to evaluate the interexaminer agreement between telephone nurses and practitioners, and practitioners and traditional diagnostic tests. RESULTS: A total of 485 patients underwent telephone interviews, and 253 (52%) completed the study protocol. kappa values showed poor agreement between nurses and practitioners for bacterial vaginosis (0.12), candidiasis (0.22), and trichomoniasis (-0.05). Practitioners failed to accurately diagnose vaginitis when kappa values were analyzed. There was also poor agreement between telephone nurses and practitioners regarding the necessity of an office visit (0.14). CONCLUSION: This prospective study challenges the notion that the telephone is an effective tool to diagnose and treat vulvovaginal complaints. Moreover, given the poor agreement between practitioners' diagnoses and microbiologic and microscopic data, further study into optimal diagnosis of vulvovaginitis is needed.
